This study estimated the extent of and factors associated with adherence to acute and continuation phase antidepressant treatment among older adults with dementia and newly diagnosed MDD.Methods: We conducted a retrospective cohort study using the Medicare 5% sample claims data (2012– 2013) among older adults (age≥ 65 years) with dementia who were newly diagnosed with MDD. Intake period of our study was from 01-May-2012 through 30-April-2013. The dependent variables of this study were acute and continuation phase depression treatment adherence. Factors associated with acute and continuation phase antidepressant treatment adherence were identified using multiple logistic regression analyses.Results: The final study sample consisted of 6239 [adherent: N=4644 (74.44%)] and 5617 [adherent: N=3584 (63.81%)] older adults with dementia and MDD during the acute and continuation phase treatment, respectively. During the acute phase, only race/ethnicity was significantly associated with adherence to depression treatment, whereas race/ethnicity and baseline antipsychotic use were significantly associated with adherence to depression treatment during the continuation phase.Conclusion: Approximately, 74% and 64% older adults with dementia and MDD were adherent to acute and continuation phase antidepressant treatment in this nationally representative sample of Medicare beneficiaries, and we identified several modifiable and non-modifiable factors associated with adherence.Keywords: dementia, depression, antidepressants, adherence, acute phase depression, continuation phase depression

Josie Acuña,1 Elaine H Situ-LaCasse,1 Asad E Patanwala,1 Lori A Stolz,2 Richard Amini,1 Lucas Friedman,3 Srikar Adhikari11Department of Emergency Medicine, University of Arizona, Tucson, AZ, USA; 2Department of Emergency Medicine, University of Cincinnati, Cincinnati, OH, USA; 3Department of Emergency Medicine, University of California-Riverside, Riverside, CA, USAObjectives: Prior literature suggests that incongruities between male and female resident’s procedural competency may be explained by gender bias during the evaluation process. There are no known studies investigating gender differences in the assessment of ultrasound-based procedural skills among emergency medicine (EM) residents. The purpose of this study was to evaluate for gender differences in ultrasound milestone assessments among EM residents.Methods: This is a retrospective study including EM residents. Milestone assessment data were collected from a total of 3 Accreditation Council for Graduate Medical Education (ACGME) EM residency programs representing a 3-year period The outcome measures included mean milestone levels, milestone levels at baseline and graduation and differences in milestone achievement between female and male EM residents. An unpaired Student’s t-test was used to compare milestone scores between female and male residents.Results: A total of 456 ultrasound milestone evaluations were collected from 91 EM residents (34 females [37%] and 57 males [63%]). No significant differences were noted in the overall mean milestone level between females (2.3±0.6) and males (2.2±0.6) (P=0.387). There were no significant differences noted in the ultrasound milestone level between females (0.8±0.6) and males (0.7±0.7) at baseline (P=0.754). Although it did not reach statistical significance (P=0.197), the increase in the mean ultrasound milestone level from baseline to graduation was greater in males (3.4±0.7) compared to females (3.1±0.7).Conclusion: Overall, there were no statistically significant differences in the mean ultrasound milestone levels between females and males. The rate of ultrasound milestone level achievement during EM residency training at our institution had a slight tendency to be higher for males than females in the observed residency programs; however, this also did not reach statistical significance. Possible gender bias while evaluating ultrasound milestone levels needs to be further studied on a larger scale.Keywords: ultrasound, gender, assessment, milestones, emergency medicine

STUDY OBJECTIVE: The primary objective of this study is to determine the activities of pharmacists that lead to medication error interception in the emergency department (ED). METHODS: This was a prospective, multicenter cohort study conducted in 4 geographically diverse academic and community EDs in the United States. Each site had clinical pharmacy services. Pharmacists at each site recorded their medication error interceptions for 250 hours of cumulative time when present in the ED (1,000 hours total for all 4 sites). Items recorded included the activities of the pharmacist that led to medication error interception, type of orders, phase of medication use process, and type of error. Independent evaluators reviewed all medication errors. Descriptive analyses were performed for all variables. RESULTS: A total of 16,446 patients presented to the EDs during the study, resulting in 364 confirmed medication error interceptions by pharmacists. The pharmacists' activities that led to medication error interception were as follows: involvement in consultative activities (n=187; 51.4%), review of medication orders (n=127; 34.9%), and other (n=50; 13.7%). The types of orders resulting in medication error interceptions were written or computerized orders (n=198; 54.4%), verbal orders (n=119; 32.7%), and other (n=47; 12.9%). Most medication error interceptions occurred during the prescribing phase of the medication use process (n=300; 82.4%) and the most common type of error was wrong dose (n=161; 44.2%). CONCLUSION: Pharmacists' review of written or computerized medication orders accounts for only a third of medication error interceptions. Most medication error interceptions occur during consultative activities. [ABSTRACT FROM AUTHOR]

PURPOSE: The case of a patient who developed aseptic meningitis, hemolytic anemia, hepatitis, and orthostatic hypotension simultaneously during treatment with trimethoprim-sulfamethoxazole is described. BACKGROUND: A healthy 37-year-old African- American man was receiving treatment with trimethoprim-sulfamethoxazole double strength. This was the patient's first experience with trimethoprim- sulfamethoxazole, and he was not taking any other medications during the treatment period. He had been taking trimethoprim-sulfamethoxazole for approximately eight days when he revisited his family physician, complaining of headaches, dizziness, difficulty with speech, weakness, and itching on the trunk of his body and legs, where a maculopapular rash was noted. Orthostatic hypotension was also noted at that visit, with a standing blood pressure measurement of 95/80 mm Hg. Based on these findings and since the patient had no signs of infection, his physician instructed him to discontinue the drug. The patient was admitted to the emergency department of a local hospital within two days due to ongoing headache, elevated temperature, and nuchal rigidity, symptoms suggestive of meningitis. Because of the presence of hemolysis, the patient underwent testing for glucose-6-phosphate dehydrogenase (G6PD) deficiency, for which he tested positive. The patient was discharged five days after admission and referred to a hematology clinic for follow-up. The patient has since returned to his routines of daily living and has reported no fatigue or other lingering adverse symptoms. CONCLUSION: A 37-year-old African- American man with G6PD deficiency developed hemolytic anemia, hepatitis, orthostatic hypotension, and aseptic meningitis simultaneously after using trimethoprim-sulfamethoxazole.

OBJECTIVE: This decision-analytic study was intended to determine the expected cost-effectiveness of linezolid compared to vancomycin for treating surgical site infections (SSIs) caused by methicillin-resistant Staphyloccocus aureus (MRSA) from the perspective of a tertiary-care academic medical center. RESEARCH DESIGN AND METHODS: This study is a cost-effectiveness analysis based on a modeling approach for the treatment of MRSA SSIs. Three clinical scenarios were considered in the decision analysis: (1) treatment with intravenous (IV) vancomycin during hospitalization and after discharge with home-care follow-up; (2) treatment with IV vancomycin during hospitalization, followed by oral linezolid after discharge; (3) treatment with oral linezolid during hospitalization and after discharge. Cost data was obtained from internal and external sources. Cure rate probabilities for MRSA SSIs were obtained from records at the medical center and from results of a randomized, multicenter trial. Healthcare costs for each scenario were obtained from the medical center, healthcare buying groups, and national databases. The robustness of the baseline cost-effectiveness determination was evaluated using sensitivity analyses over a broad range of costs and probabilities. RESULTS: Treatment with oral linezolid during hospitalization and after discharge (scenario 3) was associated with lower costs (8923, 11,479, and 12,481 dollars, respectively) and greater effectiveness (0.867, 0.787, and 0.707, respectively) compared to the IV vancomycin/oral linezolid switch (scenario 2) and IV vancomycin (scenario 1), so it dominated the latter options in the base-case, incremental cost-effectiveness analysis (10,292, 14,486, and 17,653 dollars per MRSA SSI cure, respectively). Furthermore, the sensitivity analysis demonstrated that the IV vancomycin/oral linezolid (scenario 2) option would be the expected cost-effective choice only if the length of hospitalization for this scenario was less than 6 days or if the probability of cure with oral linezolid (scenario 3) was less than or equal to 0.72; otherwise, the oral linezolid option was dominant. A major limitation of this study is the utilization of probability estimates from both institutional and published research sources. Additionally, the success rates for linezolid were obtained from one relatively small randomized, open-label trial. CONCLUSIONS: Using decision-analytic modeling, treatment with oral linezolid during hospitalization and after discharge is expected to be the most cost-effective approach for treating SSIs caused by MRSA.

Purpose. The interventions of a clinical pharmacist on an emergency department (ED) trauma response team were studied. Methods. The study site was an academic, tertiary care hospital designated as a level 1 trauma center, with a clinical pharmacist present in the ED 40 hours per week. For a two-month period, interventions by the pharmacist in trauma cases were documented in an electronic qualityimprovement database. Results. A total of 304 interventions were recorded; the most common were dosage recommendations (60%) and provision of drug information (27%). The top five drug classes involved were analgesics, sedatives, antimicrobials, vaccines, and fluids. In 83% of the interventions, the pharmacist documented involvement in facilitating drug administration. Conclusion. A pharmacist participating on the ED trauma response team commonly provided dosage recommendations and drug information, facilitated drug administration, and optimized sedation, analgesia, and antimicrobial therapy.

Background: Opioid analgesic use before total hip or knee arthroplasty has been associated with worse postoperative outcomes. This pilot study aimed to examine the feasibility of a telehealth-based pharmacist-partnered opioid tapering intervention before elective primary hip or knee arthroplasty and its potential effectiveness compared with usual care., Methods: This study was conducted at seven hospitals in New South Wales, Australia. Eligible patients were those aged ≥ 18 years, scheduled to undergo primary hip or knee arthroplasty for osteoarthritis and taking opioid analgesics pre-operatively. The intervention group participated in an opioid tapering telehealth service, a partnership between a pharmacist and general practitioner, for 3 months pre-operatively up to the day of surgery, while the control group received usual care. The primary outcomes of the study were to investigate the feasibility of the intervention (i.e. adherence to treatment) and potential effectiveness in decreasing baseline daily opioid dose by > 50% before surgery., Results: Between December 2021 and June 2023, 70 patients were recruited and assigned randomly to the intervention group (n = 35) or control group (n = 35). Baseline characteristics were similar between groups. Thirty patients in each group completed their allocated treatment. All patients allocated to the intervention group completed at least one appointment with a pharmacist, with the median (IQR [range]) being 2 (1-4 [1-6]) appointments. The number of patients who successfully decreased their baseline daily opioid dose by ≥ 50% before surgery was 27/30 in the intervention group compared with 5/30 in the usual care group (p < 0.001)., Conclusions: The findings of this pilot study support the feasibility of a telehealth-delivered, pharmacist-partnered opioid tapering service for patients scheduled for primary hip or knee arthroplasty. A broader multicentre study to examine the effectiveness of this intervention on clinical outcomes is warranted., (© 2024 The Author(s).

Background: Albumin infusions may be renally protective or harmful in patients with septic shock who have kidney impairment. This can affect the need for renal replacement therapy (RRT) and in-hospital mortality., Research Question: Does the early use of albumin mitigate the need for RRT or in-hospital mortality in patients with septic shock and kidney impairment on hospital admission., Study Design and Methods: This was a retrospective, multicenter, inverse probability-of-treatment weighted cohort study conducted in 220 geographically diverse community and teaching hospitals across the U.S. Adult patients were included if they had septic shock and kidney impairment on hospital admission. Patients were categorized as those who received albumin (within 24h of admission) or no albumin during hospitalization. Proportion of patients with RRT or in-hospital mortality were compared between groups., Results: Of the 9988 patients included in the final cohort, 7929 did not receive albumin and 2059 received albumin. Patients had a mean (SD) age of 67.8 years (14.8), 46.3% were female, and mean (SD) eGFR was 32 (12) ml/min/1.73m 2 on the day of admission. In the weighted cohort, the composite outcome of RRT or in-hospital mortality occurred in 33.8% without albumin and 39.7% with albumin (OR 1.29, 95% CI 1.14 - 1.47, p<0.001). There was no significant difference with 5% albumin (OR 1.07, 95% CI 0.84 - 1.37), but there was a significantly increased risk with 25% albumin (OR 1.43, 95% CI 1.16 - 1.76)., Interpretation: In patients with septic shock and kidney impairment on hospital admission, early albumin use may be associated with an increased composite outcome of RRT or in-hospital mortality. This increased risk is most associated with hyperoncotic rather than iso-oncotic albumin., (Copyright © 2024. Published by Elsevier Inc.)

Objectives: COVID-19 treatment guidelines recommend baricitinib or tocilizumab for the management of hospitalized patients with COVID-19. We compared the effectiveness of baricitinib vs. tocilizumab on mortality and clinical outcomes among hospitalized patients with COVID-19., Design: Multicenter, retrospective, propensity-weighted cohort study using a target trial emulation approach., Setting: The National COVID Cohort Collaborative (N3C), which is the largest electronic health records data on COVID-19 in the United States. The setting included 75 hospitals., Patients: Adults who were hospitalized for COVID-19., Interventions: Newly initiated on baricitinib or tocilizumab., Measurements and Main Results: Our primary outcome was 28-day mortality. We used propensity scores with inverse probability of treatment weights (IPTWs) to control bias and confounding while comparing treatments. Among 10,661 individuals included in the study, 6,229 (58.4%) received baricitinib and 4,432 (41.6%) tocilizumab. Overall, the mean age of the cohort was 60.0 ± 15.1 years, 6429 (60.3%) were male, and 19.2% received invasive mechanical ventilation. After IPTW adjustment, baricitinib use was associated with lower 28-day mortality (odds ratio [OR], 0.91; 95% CI, 0.85-0.98) and hospital (OR, 0.88; 95% CI, 0.82-0.94) mortality compared with tocilizumab. Baricitinib was also associated with shorter hospital length of stay (incident rate ratio, 0.92; 95% CI, 0.90-0.94) and lower rates of hospital-acquired infections (OR, 0.86; 95% CI, 0.75-0.99), although no difference in ICU length of stay was noted between the two groups., Conclusions: In this large, diverse cohort of U.S. hospitalized adults with COVID-19, baricitinib was associated with significantly lower 28-day mortality, hospital mortality, shorter hospital length of stay, and less hospital-acquired infections compared with tocilizumab., Competing Interests: Dr. Higgins is supported by a National Health and Medical Research Council Investigator Grant (GNT2008447).

Enoxaparin is dosed according to actual body weight in treatment of arterial and venous thrombosis. Due to its hydrophilic nature, it distributes according to lean body mass which may be problematic when dosing obese patients as this may increase the risk of bleeding events in this population. The aim was to evaluate current therapeutic enoxaparin dosing strategies, including Antifactor Xa (AFXa) level monitoring, in obese patients and to identify factors that contribute to treatment failure and excess anticoagulation. A retrospective cohort study was conducted reviewing patients administered therapeutic enoxaparin between May 2020 and April 2021. Data were collected on patient characteristics, enoxaparin therapy, AFXa monitoring, and outcomes. Regression models were constructed to assess variables of interest to estimate any association with AFXa levels. In total 762 patients were included in the analysis. The mean initial weight-based dose was 0.95 mg/kg twice daily (SD: ± 0.12, IQR 0.92-1.01) and 1.04 mg/kg once daily (SD: ± 0.26, IQR 0.93-1.12) and 14.4% of patients had AFXa monitoring. Treatment failure was experienced by 2.2%, 5% experienced bleeding. There was no association between the mean actual milligram per kilogram weight-based twice daily doses and subtherapeutic, therapeutic and supratherapeutic AFXa levels (P = 0.135). Obesity was not included in the final regression models due to lack of significance. At a mean therapeutic enoxaparin dose of 0.95 mg/kg twice daily and 1.04 mg/kg once daily no excess in treatment failure or bleeding events were observed in obese patients compared to the product information. Obesity was not an independent variable that affected the achievement of target AFXa levels., (© 2024. Crown.)

Background: There is little known about antibiotic de-escalation (ADE) practices in the intensive care unit (ICU)., Objective: The objective was to determine the proportion of patients who received ADE within 24 hours of actionable cultures and identify predictors of timely ADE., Methods: Multicenter cohort study in ICUs of 15 hospitals in Australia and New Zealand. Adult patients were included if they were started on broad-spectrum antibiotics within 24 hours of ICU admission. The ADE was defined as switching from a broad-spectrum agent to a narrower-spectrum agent or antibiotic cessation. The primary outcome was ADE within 24 hours of an actionable culture, where ADE was possible., Results: The 446 patients included in the study had a mean age of 63 ± 16 years, 60% were male, 32% were mechanically ventilated, and 19% were immunocompromised. Of these, 161 (36.1%) were not eligible for ADE and 37 (8.3%) for whom ADE within 24 hours of actionable culture could not be determined. In the remaining 248 patients, ADE occurred ≤24 hours in 60.5% (n = 150/248) after actionable cultures. In the multivariable logistic regression analysis, ADE was less likely to occur within 24 hours for patients with negative cultures (odds ratio [OR] = 0.48, 95% confidence interval [CI] = 0.25-0.92, P = 0.03)., Conclusion and Relevance: Timely ADE may not occur in 40% of patients in the ICU and is less likely to occur in patients with negative cultures. Timely ADE can be improved, and patients with negative cultures should be targeted as part of antimicrobial stewardship efforts., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: National Personal Health Records (PHRs) have been proposed to improve the transfer of medication-related information during transition of care. Objective: To evaluate the concordance between the medications captured in the Australian national PHR, My Health Record (MyHR), and the pharmacist obtained best possible medication history (BPMH) for patients upon hospital admission. Method: This prospective observational study used a convenience sample of hospital patients. For newly admitted patients, the investigating pharmacist obtained a BPMH and then compared it to the medication list captured in MyHR. Upon comparison, the medications were categorised into either complete match, partial match or mismatch. Medications with a complete or partial match were grouped together. Medications with deviations were then assessed for risk based on their potential consequence, and reported descriptively. A multivariable logistic regression was conducted to assess the factors associated with a drug being mismatched. Results: A total of 82 patients were recruited, with a cumulative total of 1,207 medications documented. Of the 1,207 medications, 714 (59.2%) medications were documented as a complete/partial match. The remaining 493 (40.8%) medications were mismatched. Of the 493 mismatched medications, 442 (89.7%) were deemed low-risk deviations and 51 (10.3%) were deemed high-risk. A medication was more likely to be mismatched, rather than completely/partially matched, if it was a regular non-prescription medication, or "when-required" prescription medication, or "when required" non-prescription medication, or if it was administered parenterally. Conclusion: National PHRs may be a secondary source to either confirm a patient's medication history or be used as a starting point for a BPMH., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

Background: Surgical site infection (SSI) after liver transplant (LT) is common, but no studies have been conducted in Australia. The purpose of this study was to determine the proportion of patients who developed an SSI post-LT in Australia's largest LT unit., Methods: This was a single-center retrospective cohort study. We included all LT recipients who were aged 18 years or more and received their transplant between March 1, 2018 and April 1, 2023. The primary outcome was to determine the proportion of LT recipients who developed an SSI within 30 days of transplantation., Results: There were 404 LTs performed during the study period, and 375 met inclusion criteria. Of these, 8% (n = 31/375) developed an SSI and were classified as superficial (3%, n = 12/375) or deep/organ space (5%, n = 19/375). The most common antibiotics used for prophylaxis were amoxicillin/clavulanate (75%, n = 281/375), followed by piperacillin/tazobactam (17%, n = 62/375). Independent risk factors associated with the development of SSI were Roux-en-Y hepaticojejunostomy (aOR 3.16, 95% CI 1.17-8.28, p = .02), operative time (per 60-min increment) (aOR 1.23, 95% CI 1.02-1.48), and re-operation (aOR 4.16, 95% CI 1.81-9.58, p < .01). Type of antibiotic received perioperatively was not significantly associated with SSI., Conclusion: SSI occurred in 8% of LT recipients and was predominantly related to operation-related factors rather than patient- or antibiotic-related factors., (© 2024 The Authors.

Background: Multimodal analgesia regimens are recommended for the postoperative period after hip and knee replacement surgeries. However, there are no data on practice patterns for analgesic use in the immediate postoperative period after hip and knee replacements in Australia., Objectives: To describe analgesic prescribing patterns in the inpatient postoperative phase for patients undergoing hip and knee replacement., Methods: Retrospective study of electronic medical record data from two major hospitals in Sydney, Australia. We identified analgesic medication prescriptions for all patients aged 18 years and older who underwent hip or knee replacement surgery in 2019. We extracted data on pain medications prescribed while in the ward up until discharge. These were grouped into distinct categories based on the Anatomical Therapeutic Chemical classification. We described the frequency (%) of pain medications used by category and computed the average oral morphine equivalent daily dose (OMEDD) during hospitalisation., Results: We identified 1282 surgeries in 1225 patients. Patients had a mean (SD) age of 69 (11.8) years; most (57.1%) were female. Over 99% of patients were prescribed opioid analgesics and paracetamol during their hospital stay. Most patients (61.4%) were managed with paracetamol and opioids only. The most common prescribed opioid was oxycodone (87.3% of patients). Only 19% of patients were prescribed nonsteroidal anti-inflammatories (NSAIDs). The median (IQR) average daily OMEDD was 50.2 mg (30.3-77.9)., Conclusion: We identified high use of opioids analgesics as the main strategies for pain control after hip and knee replacement in hospital. Other analgesics were much less frequently used, such as NSAIDs, and always in combination with opioids and paracetamol., (© 2024. The Author(s).)

Due to variability in pharmacokinetics and pharmacodynamics, clinical outcomes of antimicrobial drug therapy vary between patients. As such, personalised medication management, considering both pharmacokinetics and pharmacodynamics, is a growing concept of interest in the field of infectious diseases. Therapeutic drug monitoring is used to adjust and individualise drug regimens until predefined pharmacokinetic exposure targets are achieved. Minimum inhibitory concentration (drug susceptibility) is the best available pharmacodynamic parameter but is associated with many limitations. Identification of other pharmacodynamic parameters is necessary. Repurposing diagnostic biomarkers as pharmacodynamic parameters to evaluate treatment response is attractive. When combined with therapeutic drug monitoring, it could facilitate making more informed dosing decisions. We believe the approach has potential and justifies further research.

Background: Few Australian studies have examined the incidence of prescribed opioid use prior to primary total knee or total hip arthroplasty (TKA, THA) and whether it predicts post-surgery outcomes. A recent Australian study demonstrated that the prevalence of pre-arthroplasty opioid use was approximately 16%. In the United States, approximately 24% of people undergoing TKA or THA are chronic opioid users preoperatively., Purpose: This study aimed to determine (i) the proportion of TKA and THA patients who use prescribed opioids regularly (daily) before surgery (i.e., opioid use reported between the time of waitlisting and any time up to 3 months before surgery), (ii) if opioid use before surgery predicts (a) complication/readmission rates to 6-months post-surgery, and (b) patient-reported outcomes to 6-months post-surgery., Methods: A retrospective cohort study of patients who underwent TKA or THA between January 2013 and June 2018 from two Australian public hospitals was undertaken utilizing linked individual patient-level data from two prospectively collected independent databases comprising approximately 3,500 and 9,500 people (database contained known opioid usage data within the 5-year time frame). Inclusion criteria included (i) primary diagnosis of osteoarthritis of the index joint, (ii) primary elective THA or TKA, and (iii) age ≥ 18 years. Exclusion criteria included (i) revision arthroplasty, (ii) non-elective arthroplasty, (iii) hip hemiarthroplasty, (iv) uni-compartmental knee arthroplasty, and (v) previous unilateral high tibial osteotomy., Results: Analysis was completed on 1,187 study participants (64% female, 69% TKA, mean (SD) age 67 [9.9]). 30% were using regular opioids preoperatively. Adjusted regression analyses controlling for multiple co-variates indicated no significant association between preoperative opioid use and complications/readmission rates or patient-reported outcomes to 6 months post-surgery. Model diagnostics produced poor discrimination for area under the curves and non-significant goodness of fit tests. Pre-arthroplasty opioid use was associated with lower health-related quality of life (EuroQol-Visual Analogue Scale) compared to non-opioid users undergoing primary THA (mean difference -5.04 [-9.87, -0.22], P = 0.04, Adjusted R 2 = 0.06) CONCLUSION: In this study, 30% of patients were using prescribed opioids daily prior to primary TKA or THA. Pre-arthroplasty opioid use was not associated with postoperative adverse events or patient-reported pain, function, or global perceived improvement up to six months post-surgery., (© 2024.

Abstract: Management of heart failure (HF) requires the use of loop diuretics to relieve congestion and improve symptoms. When loop diuretics alone fail to induce adequate diuresis, albumin has been proposed to enhance loop diuretic delivery and promote redistribution of fluid for excretion by the kidneys. Despite the theoretical benefits of albumin, studies suggesting its benefit in HF are scarce and the co-administration of loop diuretics and albumin remains controversial. This retrospective, observational study evaluated patients with HF 18 years or older who received concomitant intravenous loop diuretic and albumin administration. The primary objective was to evaluate the association of serum albumin level with urine output (UOP) in hospitalized patients with HF who received concomitant albumin and loop diuretic therapy. Secondary endpoints included total weight loss after 72 hours, and ICU and hospital lengths of stay. In total, 276 patients were included for analysis. There was no association between initial serum albumin level and 72-hour UOP (coefficient -623.1, 95% confidence interval -1558.6 to 312.4; P = 0.191) or weight difference at 72 hours (coefficient -1.0, 95% confidence interval -2.4 to 0.3; P = 0.131). Lower albumin levels were associated with longer ICU ( P = 0.034) and hospital ( P = 0.039) lengths of stay. Concomitant thiazide diuretic use and increasing loop diuretic doses were associated with increased 72-hour UOP. The results of our study suggests that providers should avoid using baseline albumin levels as guidance for albumin dosing in HF. Given the lack of comparator groups, larger randomized controlled trials should be done to provide a definitive role for albumin to enhance diuresis in patients with HF on intravenous loop diuretics., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Oxycodone is a commonly prescribed opioid for postoperative pain. However, there has been a marked increase in the use of tapentadol over the previous decade due to a perceived superior safety profile of tapentadol compared to oxycodone. There is limited real-world evidence on the safety of tapentadol compared to oxycodone after surgery. The primary objective was to examine the impact of tapentadol compared to oxycodone use on the incidence of opioid-related adverse drug events after surgery. Data for adult surgical patients receiving tapentadol or oxycodone during hospitalization between January 1, 2018, and December 31, 2021, were collected from electronic medical records of 3 tertiary metropolitan hospitals in Australia. The primary outcome was the incidence of opioid-related adverse events. Patients receiving tapentadol or oxycodone were matched using nearest-neighbour propensity score matching. In the matched cohorts (n = 1,530 vs n = 2,775; mean [standard deviation] age 62.3 [17.0] years vs 61.9 [standard deviation 17.9] years; 43% vs 45% male for the tapentadol vs oxycodone groups, respectively), patients given tapentadol experienced a similar incidence of adverse events overall (14.4%, 220/1,530 vs 12.6%, 349/2,775; P = .100; 95% CI -.35% to 3.95%). Secondary outcomes included an increased risk of delirium (2.7%, 41/1,530 vs 1.3%, 37/2,775), arrhythmias (3.4%, 52/1,530 vs 2.2%, 62/2,775), and length of hospital stay (5 [range 1-201] vs 4 [range 1-226] days) compared with oxycodone use. Further real-world studies are warranted to determine the impact of tapentadol use on a broad range of patient outcomes. PERSPECTIVE: This study provides an early signal that tapentadol use may be associated with an increased risk of some adverse events and a longer length of stay. Further research is needed to examine the impact of tapentadol use on a broad range of patient outcomes in clinical practice settings., (Copyright © 2024 United States Association for the Study of Pain, Inc.

Objectives: The objective of this study was to compare pain control and opioid consumption in critically ill patients who were treated with buprenorphine sublingual or oxycodone oral/enteral during ICU admission., Design: This was a retrospective, parallel, cohort study., Setting: General medical or surgical ICUs of a quaternary, urban hospital in Sydney, NSW, Australia., Patients: Data were obtained for all patients admitted to two general medical or surgical ICU from January 2019 to January 2023. Patients were grouped as those who received buprenorphine sublingual versus oxycodone oral/enteral., Interventions: None., Measurements and Main Results: Pain control was compared between a propensity score matched cohort of patients who received buprenorphine versus oxycodone. The primary outcome was the probability of significant pain. A significant pain score was defined as greater than or equal to 4 on the 0-10 Numeric Rating Scale or greater than or equal to 6 on the Behavioral Pain Scale. The study cohort included 1,070 patients (288 buprenorphine and 782 oxycodone). After propensity score matching, there were 288 patients in each group. The mean age of the matched cohort was 64 ± 16 years, 295 (51%) were male, and 359 (62%) had a surgical admission. The median probability of significant pain was 0.16 with buprenorphine and 0.17 with oxycodone (median difference, 0.01; 95% CI, -0.02 to 0.04; p = 0.50). Median opioid consumption in oral morphine milligram equivalents (MMEs) was 65 with buprenorphine and 70 with oxycodone (median difference, -1 mg; 95% CI, -10 to 10 mg; p = 0.73). Median MME per ICU day was 22 with buprenorphine and 22 with oxycodone (median difference, 1 mg; 95% CI, -2 to 5 mg; p = 0.38)., Conclusions: Buprenorphine sublingual is as effective as oxycodone oral/enteral with regard to pain control and opioid consumption in the ICU. Buprenorphine sublingual is an appropriate option for patients in the ICU who are unable to take oral/enteral medications., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2023 by the Society of Critical Care Medicine and Wolters Kluwer Health, Inc.

Purpose: The primary objective was to determine the proportion of hospitals that administered norepinephrine peripheral vasopressor infusions (PVIs) in critically ill adult patients. Secondary objectives were to describe how norepinephrine is used such as the maximum duration, infusion rate and concentration, and to determine the most common first-line PVI used by country., Materials and Methods: An international multi-centre cross-sectional survey study was conducted in adult intensive care units in Australia, US, UK, Canada, and Saudi Arabia., Results: Critical care pharmacists from 132 institutions responded to the survey. Norepinephrine PVIs were utilised in 86% of institutions (n = 113/132). The median maximum duration of norepinephrine PVIs was 24 h (IQR 24-24) (n = 57/113). The most common maximum norepinephrine PVI rate was between 11 and 20 μg/min (n = 16/113). The most common maximum norepinephrine PVI concentration was 16 μg/mL (n = 60/113). Half of the institutions had a preference to administer another PVI over norepinephrine as a first-line agent (n = 66/132). The most common alternative PVI used by country was: US (phenylephrine 41%, n = 37/90), Canada (dopamine 31%, n = 5/16), UK (metaraminol 82%, n = 9/11), and Australia (metaraminol 89%, n = 8/9)., Conclusions: There is variability in clinical practice regarding PVI administration in critically ill adult patients dependent on drug availability and local institutional recommendations., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 The Authors.

Background: Total hip and knee arthroplasties are common surgeries performed worldwide, but the management of pain during the subacute period (defined as hospital discharge to 3 months postoperatively) is poorly understood. This study aimed to determine patients' experiences, facilitators and barriers to subacute pain management following total hip or knee arthroplasty., Methods: Semi-structured interviews with a purposive sample of patients following total hip or knee arthroplasty were conducted between June and August 2022. Participants were recruited from two tertiary metropolitan hospitals. Interviews were audio-recorded and transcribed verbatim. Data were analysed using an inductive thematic approach to identify common themes., Results: In total, 30 interviews were conducted with patients following hip or knee arthroplasty. Four main themes were identified: (i) Physical constitution before surgery (joint condition, analgesic use, age, and hearing); (ii) Attitude and knowledge (motivation, outlook on life, attitude towards taking medications, individual benchmarking, and knowledge); (iii) Socio-ethno-cultural factors (family and community connection, language, and religion), and (iv) Health-system support (health-professional delivered education, medications, services, staff, and costs)., Conclusions: Participants' experiences of subacute pain following hip or knee arthroplasty were shaped by multidimensional factors. Strategies to empower patients through increased education and support during postoperative opioid tapering as well as a shift to a biopsychosocial approach to pain management during the subacute period may improve patient and health-system outcomes., (© 2023 The Authors.

Transdermal buprenorphine (TBUP) may have some advantages for the management of acute postoperative pain. The aim of this systematic review and meta-analysis was to investigate the efficacy and safety of TBUP compared to other analgesics or placebo for acute postoperative pain. A systematic search was conducted using Embase, MEDLINE, and Cochrane Central Register of Controlled Trials (CENTRAL) until December 26, 2022. The search included randomized controlled trials comparing TBUP versus other analgesics or placebo for acute postoperative pain. A certainty assessment was conducted using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. The protocol for this review was registered on Prospective Register of Systematic Reviews (CRD42022318601). In total, 15 studies involving 1,205 participants were included that compared TBUP versus fentanyl (n = 2), celecoxib (n = 3), placebo (n = 2), tramadol (n = 5), diclofenac (n = 3), parecoxib (n = 1), and flurbiprofen (n = 1). Meta-analyses were conducted for 3 comparators that involved 2 studies each. There was no significant difference in pain between TBUP 10 mcg/h versus fentanyl 25 mcg/h (standardized mean difference [SMD] -.03, 95% confidence interval [CI] -.86 to .81, P = .95, I 2 = 85%). TBUP 10 mcg/h was associated with less pain compared to celecoxib 200 mg twice daily (SMD -.32, 95% CI -.58 to -.05, P = .02, I 2 = 0%) and placebo (SMD -2.29, 95% CI -4.32 to -.27, P = .03, I 2 = 94%). The GRADE assessment showed a very low certainty of evidence for all comparisons. There is insufficient evidence that TBUP improves pain control compared to other analgesics for acute postoperative pain. PERSPECTIVE: This systematic review and meta-analysis compared the use of TBUP to other analgesics for postoperative pain. The results showed that there is insufficient evidence to recommend the use of TBUP in this setting. The findings will help clinicians select the most appropriate opioid regimens for postoperative pain., (Copyright © 2023 United States Association for the Study of Pain, Inc.

Rationale: Controversies and practice variations exist related to the pharmacologic and nonpharmacologic management of the airway during rapid sequence intubation (RSI)., Objectives: To develop evidence-based recommendations on pharmacologic and nonpharmacologic topics related to RSI., Design: A guideline panel of 20 Society of Critical Care Medicine members with experience with RSI and emergency airway management met virtually at least monthly from the panel's inception in 2018 through 2020 and face-to-face at the 2020 Critical Care Congress. The guideline panel included pharmacists, physicians, a nurse practitioner, and a respiratory therapist with experience in emergency medicine, critical care medicine, anesthesiology, and prehospital medicine; consultation with a methodologist and librarian was available. A formal conflict of interest policy was followed and enforced throughout the guidelines-development process., Methods: Panelists created Population, Intervention, Comparison, and Outcome (PICO) questions and voted to select the most clinically relevant questions for inclusion in the guideline. Each question was assigned to a pair of panelists, who refined the PICO wording and reviewed the best available evidence using predetermined search terms. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework was used throughout and recommendations of "strong" or "conditional" were made for each PICO question based on quality of evidence and panel consensus. Recommendations were provided when evidence was actionable; suggestions, when evidence was equivocal; and best practice statements, when the benefits of the intervention outweighed the risks, but direct evidence to support the intervention did not exist., Results: From the original 35 proposed PICO questions, 10 were selected. The RSI guideline panel issued one recommendation (strong, low-quality evidence), seven suggestions (all conditional recommendations with moderate-, low-, or very low-quality evidence), and two best practice statements. The panel made two suggestions for a single PICO question and did not make any suggestions for one PICO question due to lack of evidence., Conclusions: Using GRADE principles, the interdisciplinary panel found substantial agreement with respect to the evidence supporting recommendations for RSI. The panel also identified literature gaps that might be addressed by future research., Competing Interests: Dr. Mosier is currently the National Course Director for the Difficult Airway Course: Critical Care. Dr. Heffner received funding as an advisor/speaker. Drs. Mosier, Hirsch, Heffner, and Gunnerson have served as expert witness.

Modified-release opioids are often prescribed for the management of moderate to severe acute pain following total hip and knee arthroplasty, despite recommendations against their use due to increasing concerns regarding harm. The primary objective of this multicentre study was to examine the impact of modified-release opioid use on the incidence of opioid-related adverse events compared with immediate-release opioid use, among adult inpatients following total hip or knee arthroplasty. Data for total hip and knee arthroplasty inpatients receiving an opioid analgesic for postoperative analgesia during hospitalisation were collected from electronic medical records of three tertiary metropolitan hospitals in Australia. The primary outcome was the incidence of opioid-related adverse events during hospital admission. Patients who received modified with or without immediate-release opioids were matched to those receiving immediate-release opioids only (1:1) using nearest neighbour propensity score matching with patient and clinical characteristics as covariates. This included total opioid dose received. In the matched cohorts, patients given modified-release opioids (n = 347) experienced a higher incidence of opioid-related adverse events overall, compared with those given immediate-release opioids only (20.5%, 71/347 vs. 12.7%, 44/347; difference in proportions 7.8% [95%CI 2.3-13.3%]). Modified-release opioid use was associated with an increased risk of harm when used for acute pain during hospitalisation after total hip or knee arthroplasty., (© 2023 The Authors.

Prescription of modified-release opioids for acute postoperative pain is widespread despite evidence to show their use may be associated with an increased risk of adverse effects. This systematic review and meta-analysis aimed to examine the available evidence on the safety and efficacy of modified-release, compared with immediate-release, oral opioids for postoperative pain in adults. We searched five electronic databases from 1 January 2003 to 1 January 2023. Published randomised clinical trials and observational studies on adults who underwent surgery which compared those who received oral modified-release opioids postoperatively with those receiving oral immediate-release opioids were included. Two reviewers independently extracted data on the primary outcomes of safety (incidence of adverse events) and efficacy (pain intensity, analgesic and opioid use, and physical function) and secondary outcomes (length of hospital stay, hospital readmission, psychological function, costs, and quality of life) up to 12 months postoperatively. Of the eight articles included, five were randomised clinical trials and three were observational studies. The overall quality of evidence was low. Modified-release opioid use was associated with a higher incidence of adverse events (n = 645, odds ratio (95%CI) 2.76 (1.52-5.04)) and worse pain (n = 550, standardised mean difference (95%CI) 0.2 (0.04-0.37)) compared with immediate-release opioid use following surgery. Our narrative synthesis concluded that modified-release opioids showed no superiority over immediate-release opioids for analgesic consumption, length of hospital stay, hospital readmissions or physical function after surgery. One study showed that modified-release opioid use is associated with higher rates of persistent postoperative opioid use compared with immediate-release opioid use. None of the included studies reported on psychological function, costs or quality of life., (© 2023 The Authors.

Purpose: To provide key pharmacological concepts underlying drug-drug interactions (DDIs), a decision-making framework, and a list of DDIs that should be considered in the context of contemporary acutely ill patients with COVID-19., Summary: DDIs are frequently encountered in the acutely ill. The implications of DDIs include either increased risk of drug toxicity or decreased effectiveness, which may have severe consequences in the acutely ill due to lower physiological and neurocognitive reserves in these patients. In addition, an array of additional therapies and drug classes have been used for COVID-19 that were not typically used in the acute care setting. In this update on DDIs in the acutely ill, we provide key pharmacological concepts underlying DDIs, including a discussion of the gastric environment, the cytochrome P-450 (CYP) isozyme system, transporters, and pharmacodynamics in relation to DDIs. We also provide a decision-making framework that elucidates the identification of DDIs, risk assessment, selection of alternative therapies, and monitoring. Finally, important DDIs pertaining to contemporary acute care clinical practice related to COVID-19 are discussed., Conclusion: Interpreting and managing DDIs should follow a pharmacologically based approach and a systematic decision-making process to optimize patient outcomes., (© American Society of Health-System Pharmacists 2023.)

Opioid analgesics prescribed for the management of acute pain following orthopaedic surgery may lead to unintended long-term opioid use and associated patient harms. This study aimed to examine the prevalence of opioid use at 90 days after elective orthopaedic surgery across major city, regional and rural locations in New South Wales, Australia. We conducted a prospective, observational cohort study of patients undergoing elective orthopaedic surgery at five hospitals from major city, regional, rural, public and private settings between April 2017 and February 2020. Data were collected by patient questionnaire at the pre-admission clinic 2-6 weeks before surgery and by telephone call after 90 days following surgery. Of the 361 participants recruited, 54% (195/361) were women and the mean age was 67.7 years (standard deviation 10.1 years). Opioid use at 90 or more days after orthopaedic surgery was reported by 15.8% (57/361; 95% confidence interval (CI) 12.2-20%) of all participants and ranged from 3.5% (2/57) at a major city location to 37.8% (14/37) at an inner regional location. Predictors of long-term postoperative opioid use in the multivariable analysis were surgery performed at an inner regional location (adjusted odds ratio 12.26; 95% CI 2.2-68.24) and outer regional location (adjusted odds ratio 5.46; 95% CI 1.09-27.50) after adjusting for known covariates. Long-term opioid use was reported in over 15% of patients following orthopaedic surgery and appears to be more prevalent in regional locations in Australia.

Opioid analgesics are commonly used by patients awaiting orthopaedic surgery, and preoperative opioid use is associated with a greater burden of postoperative pain, suboptimal surgical outcomes and higher healthcare costs. This study aimed to examine the prevalence of total opioid use before elective orthopaedic surgery with a focus on regional and rural hospitals in New South Wales, Australia. This was a cross-sectional, observational study of patients undergoing orthopaedic surgery conducted between April 2017 and November 2019 across five hospitals that included a mix of metropolitan, regional, rural, private and public settings. Preoperative patient demographics, pain scores and analgesic use were collected during pre-admission clinic visits, held between two and six weeks before surgery. Of the 430 patients included, 229 (53.3%) were women and the mean age was 67.5 (standard deviation 10.1) years. The overall prevalence of total preoperative opioid use was 37.7% (162/430). Rates of preoperative opioid use ranged from 20.6% (13/63) at a metropolitan hospital to 48.8% (21/43) at an inner regional hospital. Multivariable logistic regression showed that the inner regional setting was a significant predictor of opioid use before orthopaedic surgery (adjusted odds ratio 2.6; 95% confidence interval 1.0 to 6.7) after adjusting for covariates. Opioid use prior to orthopaedic surgery is common and appears to vary by geographical location.

Background: Medication reconciliation is an effective strategy to reduce medication errors upon hospital admission. The process involves obtaining a best possible medication history (BPMH), which can be both time-consuming and resource-intensive. During the COVID-19 pandemic, telepharmacy was used to reduce the risk of viral transmission. Telepharmacy is the remote provision of pharmacy-led clinical services, such as obtaining BPMHs, using telecommunications. However, the accuracy of telephone-obtained BPMHs has not yet been evaluated. Therefore, the primary aim of this study was to evaluate the proportion of patients who have an accurate BPMH from the telephone-obtained BPMH compared to an in-person obtained BPMH., Methods: This prospective, observational study took place in a large tertiary hospital. Recruited patients or carers had their BPMH obtained by a pharmacist over the telephone. The same patients or carers then had their BPMH conducted in-person to identify any deviations between the telephone-obtained and in-person obtained BPMH. All telephone-obtained BPMHs were timed with a stopwatch. Any deviations were categorised according to their potential consequence. An accurate BPMH was defined as having no deviations. Descriptive statistics were used to report all quantitative variables. A multivariable logistic regression was conducted to identify risk factors for patients and medications for having medication deviations., Results: In total, 116 patients were recruited to receive both a telephone-obtained and in-person obtained BPMH. Of these, 91 patients (78%) had an accurate BPMH with no deviations. Of the 1104 medications documented across all the BPMHs, 1064 (96%) had no deviation. Of the 40 (4%) medication deviations, 38 were deemed low-risk (3%) and 2 high-risk (1%). A patient was more likely to have a deviation if they are taking more medications (aOR: 1.11; 95% CI: 1.01-1.22; p < 0.05). A medication was more likely to have a deviation if it was regular non-prescription medication (aOR: 4.82; 95% CI: 2.14-10.82; p < 0.001) or 'when required' non-prescription medication (aOR: 3.12; 95% CI: 1.20-8.11; p = 0.02) or a topical medication (aOR: 12.53; 95% CI: 4.34-42.17; p < 0.001)., Conclusions: Telepharmacy represents a reliable and time-efficient alternative to in-person BPMHs., (© 2023.

Background: Medication-related hospitalisations present an opportunity for de-prescribing and simplification of medication regimens. The Medication Regimen Complexity Index (MRCI) is a tool for measuring the complexity of medication regimens., Objectives: To evaluate whether MRCI changes following medication-related hospitalisations, and to evaluate the relationship between MRCI, length of stay (LOS) in hospital, and patient characteristics., Methods: A retrospective medical record review of patients admitted to a tertiary referral hospital in Australia for medication-related problems, January 2019 to August 2020. MRCI was calculated using pre-admission medication lists and discharge medication lists., Results: There were 125 patients who met inclusion criteria. The median (IQR) age was 64.0 years (45.0-75.0) and 46.4% were female. Median MRCI decreased by 2.0 following hospitalisation: from median (IQR) 17.0 (7.0-34.5) on admission vs 15.0 (3.0-29.0) on discharge (p < 0.001). Admission MRCI predicted LOS ≥2 days (OR 1.03, 95%CI 1.00-1.05, p = 0.022). Allergic reaction-related hospitalisations were associated with lower admission MRCI., Conclusions: There was a decrease in MRCI following medication-related hospitalisation. Targeted medication reviews for high-risk patients (e.g., those with medication-related hospitalisations) could further reduce the burden of medication complexity following discharge from hospital and possibly prevent readmissions., (Copyright © 2023 The Authors.

Background: Pediatric emergency intubation is a high-acuity, low-occurrence procedure. Despite advances in technology, the success of this procedure remains low and adverse events are very high. Prospective observational studies in children have demonstrated improved success with the use of video laryngoscopy (VL) compared with direct laryngoscopy, although reported first-pass success (FPS) rates are lower than that reported for adults. This may in part be due to difficulty directing the tracheal tube to the laryngeal inlet considering the cephalad position of the larynx in infants. Using airway adjuncts such as the pediatric rigid stylet (PRS) or a tracheal tube introducer (TTI) may aid with intubation to the cephalad positioned airway when performing VL. The objectives of this study were to assess the FPS and time to intubation when intubating an infant manikin with a standard malleable stylet (SMS) compared with a PRS and TTI., Methods: This was a randomized cross-over study performed at an academic institution both with emergency medicine (EM) and combined pediatric and EM (EM&PEDS) residency programs. Emergency medicine and EM&PEDS residents were recruited to participate. Each resident performed intubations on a 6-month-old infant simulator using a standard geometry C-MAC Miller 1 video laryngoscope and 3 different intubation adjuncts (SMS, PRS, TTI) in a randomized fashion. All sessions were video recorded for data analysis. The primary outcome was FPS using the 3 different intubation adjuncts. The secondary outcome was the mean time to intubation (in seconds) for each adjunct., Results: Fifty-one participants performed 227 intubations. First-pass success with the SMS was 73% (37/51), FPS was 94% (48/51) with the PRS, and 29% (15/51) with the TTI. First-pass success was lower with the SMS (-43%; 95% confidence interval [CI], -63% to -23%; P < 0.01) and significantly lower with the TTI compared with PRS (difference -65%; 95% CI, -81% to -49%; P < 0.01). First-pass success while using the PRS was higher than SMS (difference 22%, 7% to 36%; P < 0.01). The mean time to intubation using the SMS was 44 ± 13 seconds, the PRS was 38 ± 11 seconds, and TTI was 59 ± 15 seconds. The mean time to intubation was higher with SMS (difference 15 seconds; 95% CI, 10 to 20 seconds; P < 0.01) and significantly higher with the TTI compared with PRS (difference 21 seconds; 95% CI, 17 to 26 seconds; P < 0.01). Time to intubation with the PRS was lower than SMS (difference -7 seconds; 95% CI, -11 to -2 seconds; P < 0.01). The ease of use was significantly higher for the PRS compared with the TTI when operators rated them on a visual analog scale (91 vs 20 mm)., Conclusions: Use of the PRS by EM and EM&PEDS residents on an infant simulator was associated with increased FPS and shorter time to intubation. Clinical studies are warranted comparing these intubation aids in children., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Linezolid is a broad-spectrum antimicrobial with limited use due to toxicity. This study aimed to evaluate linezolid toxicity in a large multicentre cohort. Secondary objectives were to identify factors contributing to toxicity, including the impact of therapeutic drug monitoring (TDM)., Methods: Patients administered linezolid between January 2017 and December 2019 were retrospectively reviewed. Data were collected on patient characteristics, linezolid therapy and outcomes. Descriptive statistics were performed on all patients, and statistical comparisons were undertaken between those who did and did not experience linezolid toxicity. A multivariable logistic regression model was constructed to identify any covariates that correlated with toxicity., Results: Linezolid was administered to 1050 patients; of these, 381 did not meet the inclusion criteria and 47 were excluded as therapy ceased for non-toxicity reasons. There were 105 of 622 (16.9%) patients assessed to have linezolid toxicity. Patients who experienced toxicity displayed a higher baseline creatinine (96.5 µmol/L vs. 79 µmol/L; P = 0.025), lower baseline platelet count (225 × 10 9 /L vs. 278.5 × 10 9 /L; P = 0.002) and received a longer course (median 21 vs. 14 days; P < 0.001) than those who did not. Linezolid TDM was performed in 144 patients (23%). Multivariable logistic regression demonstrated that TDM-guided appropriate dose adjustment significantly reduced the odds of linezolid toxicity (aOR = 0.45; 95% CI 0.21-0.96; P = 0.038) and a treatment duration > 28 days was no longer significantly associated with toxicity., Conclusions: This study confirmed that linezolid treatment-limiting toxicity remains a problem and suggests that TDM-guided dose optimisation may reduce the risk of toxicity and facilitate prolonged courses beyond 28 days., (Crown Copyright © 2023.

Background: Hospital-acquired venous thromboembolism (VTE) is a major cause of morbidity and mortality., Aims: To determine the proportion of patients with hospital-acquired VTE that are preventable., Methods: This was a retrospective study of patients in two tertiary care hospitals in Sydney, Australia. Data were collected for patients with hospital-acquired VTE based on International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM) coding from January 2018 to May 2020. Patients were classified as low, moderate or high risk of developing a VTE during hospitalisation based on demographic and clinical factors. A hospital-acquired VTE was considered to be potentially preventable if there was suboptimal prophylaxis in the absence of contraindications. Suboptimal therapy included at least one of the following related to VTE prophylaxis: low dose, missed dose (prior to developing a VTE), suboptimal drug and delayed start (>24 h from admission)., Results: There were 229 patients identified with VTE based on ICD-10-AM coding. A subset of 135 patients were determined to have actual hospital-acquired VTE. Of these, there were no patients at low risk, 64% (87/135) at moderate risk and 44% (48/135) at high risk of developing a VTE. Most (65%; n = 88/135) patients had one or more contraindications to receive recommended prophylaxis. Overall, the proportion of patients who received suboptimal prophylaxis was 11% (15/135)., Conclusion: Approximately one out of 10 hospital-acquired VTE are preventable. Hospitals should focus on measuring and reporting VTE that are preventable to provide a more accurate measure of the burden of VTE that can be reduced by improving care., (© 2021 Royal Australasian College of Physicians.)

Background: Medication reconciliation is an effective strategy to prevent medication errors upon hospital admission and requires obtaining a patient's best possible mediation history (BPMH). However, obtaining a BPMH is time-consuming and pharmacy students may assist pharmacists in this task., Aim: To evaluate the proportion of patients who have an accurate BPMH from the pharmacy student-obtained BPMH compared to the pharmacist-obtained BPMH., Method: Twelve final-year pharmacy students were trained to obtain BPMHs upon admission at 2 tertiary hospitals and worked in pairs. Each student pair completed one 8-h shift each week for 8 weeks. Students obtained BPMHs for patients taking 5 or more medications. A pharmacist then independently obtained and checked the student BPMH from the same patient for accuracy. Deviations were determined between student-obtained and pharmacist-obtained BMPH. An accurate BPMH was defined as only having no-or-low risk medication deviations., Results: The pharmacy students took BPMHs for 91 patients. Of these, 65 patients (71.4%) had an accurate BPMH. Of the 1170 medications included in patients' BPMH, 1118 (95.6%) were deemed accurate. For the student-obtained BPMHs, they were more likely to be accurate for patients who were older (OR 1.04; 95% CI 1.03-1.06; p < 0.001), had fewer medications (OR 0.85; 95% CI 0.75-0.97; p = 0.02), and if students used two source types (administration and supplier) to obtain the BPMH (OR 1.65; 95% CI 1.09-2.50; p = 0.02)., Conclusion: It is suitable for final-year pharmacy students to be incorporated into the BPMHs process and for their BPMHs to be verified for accuracy by a pharmacist., (© 2022.

This study aims to summarize the effectiveness of organizational interventions on appropriate opioid prescribing for noncancer pain upon hospital discharge. A systematic search was conducted on 6 electronic databases by 2 independent reviewers. We included original research articles reporting on quantitative outcomes of organizational interventions targeting appropriate opioid prescribing on hospital discharge. Quality assessment was performed by 2 independent reviewers. The protocol for this review was prospectively registered on PROSPERO (ID: CRD42020156104). Out of 173 full texts assessed for eligibility, 43 were included in this review. The majority of studies had a moderate to serious risk of bias (33 out of 43). Most of the studies implemented a multifaceted organizational intervention (16 studies). Other interventions included guideline implementation, prescriber education and default opioid-prescribing quantity changes in electronic medical records. Multiple studies found that the dissemination of patient-specific and procedure-specific guidelines reduced the quantity of opioids prescribed by 44 to 57%. Prescriber education provided with feedback was implemented in 4 studies and resulted in a 33 to 44% decrease in prescribing rates. Lowering the default quantities in the electronic medical records produced a 40% decrease in opioids prescribed in 1 study. Guideline implementation, prescriber education and default opioid-prescribing quantity changes all appear effective in improving the appropriate prescribing of opioids on hospital discharge. However, the extent of reduction of opioid prescribing upon hospital discharge after the implementation of multifaceted intervention strategies appears similar to that of simpler interventions which require fewer resources., (© 2022 The Authors.

Purpose: To assess the agreement in 24-hour area under the curve (AUC 24 ) value estimates between commonly used vancomycin population pharmacokinetic models in the critically ill., Materials and Methods: Adults admitted to intensive care who received intravenous vancomycin and had a serum vancomycin concentration available were included. AUC 24 values were determined using Tucuxi (revision cd7bd7a8) for dosing intervals with a vancomycin concentration using three models (Goti 2018, Colin 2019, and Thomson 2009) previously evaluated in the critically ill. AUC 24 values were categorized as subtherapeutic (<400 mg·h/L), therapeutic (400-600 mg·h/L), or toxic (>600 mg·h/L), assuming a minimum inhibitory concentration of 1 mg/L. AUC 24 value categorization was compared across the three models and reported as percent agreement., Results: Overall, 466 AUC 24 values were estimated in 188 patients. Overall, 52%, 42%, and 47% of the AUC 24 values were therapeutic for the Goti, Colin, and Thomson models, respectively. The agreement of AUC 24 values between all three models was 48% (223/466), Goti-Colin 59% (193/466), Goti-Thomson 68% (318/466), and Colin-Thomson 67% (314/466)., Conclusion: In critically ill patients, vancomycin AUC 24 values obtained from different pharmacokinetic models are often discordant, potentially contributing to differences in dosing decisions. This highlights the importance of selecting the optimal model., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2022 Asad E. Patanwala et al.)

Background: The comparative benefits and harms of opioids for musculoskeletal pain in the emergency department (ED) are uncertain., Purpose: To evaluate the comparative effectiveness and harms of opioids for musculoskeletal pain in the ED setting., Data Sources: Electronic databases and registries from inception to 7 February 2022., Study Selection: Randomized controlled trials of any opioid analgesic compared with placebo or a nonopioid analgesic administered or prescribed to adults in or on discharge from the ED., Data Extraction: Pain and disability were rated on a scale of 0 to 100 and pooled using a random-effects model. Certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework., Data Synthesis: Forty-two articles were included ( n  = 6128). In the ED, opioids were statistically but not clinically more effective in reducing pain in the short term (about 2 hours) than placebo and paracetamol (acetaminophen) but were not clinically or statistically more effective than nonsteroidal anti-inflammatory drugs (NSAIDs) or local or systemic anesthetics. Opioids may carry higher risk for harms than placebo, paracetamol, or NSAIDs, although evidence is very uncertain. There was no evidence of difference in harms associated with local or systemic anesthetics., Limitations: Low or very low GRADE ratings for some outcomes, unexplained heterogeneity, and little information on long-term outcomes., Conclusion: The risk-benefit balance of opioids versus placebo, paracetamol, NSAIDs, and local or systemic anesthetics is uncertain. Opioids may have equivalent pain outcomes compared with NSAIDs, but evidence on comparisons of harms is very uncertain and heterogeneous. Although factors such as route of administration or dosage may explain some heterogeneity, more work is needed to identify which subgroups will have a more favorable benefit-risk balance for one analgesic over another. Longer-term pain management once dose thresholds are reached is also uncertain., Primary Funding Source: None. (PROSPERO: CRD42021275293).

Background: Total knee arthroplasty (TKA) and total hip arthroplasty (THA) surgeries are among the most common elective procedures. Moderate to severe postoperative pain during the subacute period (defined here as the period from hospital discharge to 3 months postoperatively) is a predictor of persistent pain 12 months postoperatively. This review aimed to examine the available postdischarge pharmacological interventions, including educational and prescribing strategies, and their effect on reducing pain during the subacute period after TKA or THA., Methods: We searched seven electronic databases from inception to April 22, 2021. Published randomized controlled trials of adults who underwent TKA or THA and received a pharmacological-based intervention commencing within 1 week after hospital discharge and conducted for up to 3 months postoperatively were compared with any treatment. Two reviewers independently extracted data on the primary outcome, pain intensity. This review was registered prospectively on PROSPERO (ID: CRD42021250384)., Results: Four trials involving 660 participants were included. Interventions included changing analgesic prescribing practices upon hospital discharge and education on analgesic use. Providing multimodal non-opioid analgesia in addition to reduced opioid quantity was associated with lower subacute pain (coefficient -0.81; 95% confidence interval -1.33 to -0.29; P = 0.003). Education on analgesic use during multidisciplinary home visits was effective for reducing pain intensity during the subacute period (6.25 ± 10.13 vs 35.67 ± 22.05; P < 0.001) compared with usual care., Conclusions: Interventions involving the provision of multimodal non-opioid analgesia and education on analgesic use show positive effects on reducing pain intensity during the subacute period after TKA and THA., (© The Author(s) 2022.
