Introduction: Multidisciplinary tumor boards (TBs) are crucial for decision-making and management of patients diagnosed with complex malignancies. The social distancing conditions imposed by coronavirus disease 2019 presented an opportunity to compare virtual versus in-person TBs., Methods: A retrospective analysis of attendance data from an National Cancer Institute-designated cancer center's gastrointestinal (GI) TB participant data from September 2019 to October 2020. In addition, an online survey assessing the virtual TB experience was sent to participants of all TBs. Interrupted time series analyses were performed to evaluate preintervention and postintervention GI TB attendance only., Results: The overall mean attendance for GI TB was 30 participants; turnout was higher for virtual format compared to in-person (32 versus 23 attendees, P < 0.001). This increase was seen across all participant categories: attending physicians (15 versus 11 attendees, P < 0.001), trainees (11 versus 8, P < 0.001), and support staff (6 versus 3, P < 0.001). There was no significant difference in the mean number of cases discussed between TB formats. The majority of the 141 survey respondents (across all TB) were attending physicians with >20-year experience. Most supported a permanent virtual or hybrid TB format, 72.5% found this format to be more time efficient and with similar productivity, and 85.8% found it easier to attend. The majority (89.9%) felt confident that the decision-making process was not affected by virtual interactions., Conclusions: A virtual platform for multispecialty TBs allows for greater attendance without sacrificing the decision-making process. This survey supports continuing with a virtual or hybrid format, which may increase attendance and facilitate access to multidisciplinary discussions leading to improved patient care., (Copyright © 2022 Elsevier Inc.

Background: Multiple neoadjuvant therapy protocols have been proposed in the treatment of pancreatic adenocarcinoma, including chemotherapy (CT), chemoradiation (CRT), and total neoadjuvant therapy (TNT), defined as a CT plus CRT. A pathologic complete response (pCR) can be achieved in a minority of cases. We hypothesize that TNT is more likely to confer pCR than other neoadjuvant therapies, which may improve overall survival (OS)., Methods: A retrospective review of the National Cancer Database (NCDB) from 2006 to 2016 was performed, identifying patients who underwent any neoadjuvant therapy followed by definitive pancreatic resection for locally advanced or borderline resectable pancreatic adenocarcinoma. A pathologic complete response was defined as down-staging from any clinical stage to pathologic stage 0., Results: A total of 5402 patients who received neoadjuvant therapy followed by resection were identified. 177 patients (3.3%) achieved a pCR. Of the patients who achieved a pCR, 57 received CT, 41 CRT and 79 received TNT. On multivariate analysis, TNT was more likely to confer a pCR than CRT (OR 1.67, CI 1.13-2.46, p = 0.0103) or CT (OR 2.61, CI 1.83-3.71, p < 0.0001). Patients who achieved pCR had a significantly higher OS, with median survival of 64.9 months, compared to 21.6 months in patients who did not achieve pCR (p < 0.0001)., Conclusion: TNT may be more likely to achieve a pCR than CT or CRT. Patients who achieve a pCR have a significant OS benefit as compared to those who have residual disease. TNT should be considered for patients requiring neoadjuvant therapy, as it may increase the likelihood of achieving a pCR, thus potentially improving OS., (Copyright © 2021.

Tumor mutational burden (TMB) has recently been identified as a biomarker of response to immune checkpoint inhibitors in many cancers, including melanoma. Co-assessment of TMB with inflammatory markers and genetic mutations may better predict disease outcomes. The goal of this study was to evaluate the potential for TMB and somatic mutations in combination to predict the recurrence of disease in advanced melanoma. A retrospective review of 85 patients with stage III or IV melanoma whose tumors were analyzed by next-generation sequencing was conducted. Fisher's exact test was used to assess differences in TMB category by somatic mutation status as well as recurrence locations. Kaplan-Meier estimates and Cox-proportional regression model were used for survival analyses. The most frequently detected mutations were TERT (32.9%), CDKN2A (28.2%), KMT2 (25.9%), BRAF V600E (24.7%), and NRAS (24.7%). Patients with TMB-L + BRAFWT status were more likely to have a recurrence [hazard ratio (HR), 3.43; confidence interval (CI), 1.29-9.15; P = 0.01] compared to TMB-H + BRAF WT. Patients with TMB-L + NRASmut were more likely to have a recurrence (HR, 5.29; 95% CI, 1.44-19.45; P = 0.01) compared to TMB-H + NRAS WT. TMB-L tumors were associated with local (P = 0.029) and in-transit (P = 0.004) recurrences. Analysis of TMB alone may be insufficient in understanding the relationship between melanoma's molecular profile and the body's immune system. Classification into BRAFmut, NRASmut, and tumor mutational load groups may aid in identifying patients who are more likely to have disease recurrence in advanced melanoma., (Copyright © 2022 Wolters Kluwer Health, Inc.

Both BRAF/MEK targeted agents and immunotherapy are approved for the treatment of advanced melanoma. BRAF testing is recommended at the time of advanced melanoma diagnosis. In addition, little is known regarding the treatment trends for patients with BRAF mutated tumors. This investigation aims to assess the real-world prevalence of molecular testing and treatment trends for patients with BRAF mutated tumors. Using a de-identified database, patients of age ≥18 years with advanced melanoma from 2013 to 2018 were examined. Molecular testing performed within 3 months of advanced diagnosis was considered to have the test performed at the time of diagnosis. Test prevalence was calculated and compared in groups stratified by the patient, tumor and treatment factors. In total 4459 patients were included; 1936 (43.4%) stage III, 1191 (26.7%) stage IV and 1332 (29.9%) recurrent. Totally 50.4% of patients received systemic treatment; 76.4% stage IV, 71% recurrent patients and 26.7% stage III patients. However, 73.5% received first-line immunotherapy. In total 73.8% of patients had molecular testing, and 50.5% had tested at the time of advanced diagnosis. Of those tested 42% had a BRAF mutated tumor. In total 48% of these patients received first-line immunotherapy whereas 43% received a BRAF inhibitor, with increasing immunotherapy use seen over time. The majority of patients with advanced melanoma undergo molecular testing at the time of advanced diagnosis. Immunotherapy is the most commonly prescribed treatment regardless of BRAF mutational status. These results provide real-world data on the frequency of molecular testing and treatment trends for patients with advanced melanoma., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: Opioids are prescribed excessively following surgery. As many urologic oncology procedures are performed minimally invasively, an opportunity exists to push forward initiatives to minimize postoperative opioid use., Materials and Methods: A quality improvement initiative to reduce inpatient opioid prescribing was launched at a tertiary cancer center. In Phase I (December 2019-July 2020), providers were instructed to start standing acetaminophen. In Phase II (beginning August 2020), education was provided to the entire care team and ordersets were modified to an opioid sparing protocol (OSP). We analyzed the proportion of minimally invasive surgery (MIS) prostatectomy and nephrectomy patients that adhered to an OSP during each phase and compared them to controls from the preceding 2 years., Results: A total of 303, 153, and 839 patients underwent MIS during the Phase I, Phase II, and control periods respectively. The proportion of patients adhering to an OSP increased from 16% at the beginning of Phase I to 76% at the end of Phase II (p-trend < 0.001). The median total oral morphine equivalents for oral opioids declined from 20 mg and 40 mg at baseline for prostatectomy and nephrectomy patients respectively to 0 mg for both groups (p-trends < 0.001). Multivariable analysis found that patients received 22% and 81% less oral morphine equivalents during Phase I and II respectively compared to the control period (P < 0.001)., Conclusions: Adherence to an OSP is most effective when initiatives incorporate the entire team and are supported by nudge theory-based structural changes. Using these strategies, most patients following urologic MIS can dramatically reduce opioid use postoperatively., Competing Interests: Conflict of interest The authors have no conflicts of interest to disclose., (Copyright © 2021.

Background: Surgical delays are associated with invasive cancer for patients with ductal carcinoma in situ (DCIS). During the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) pandemic, neoadjuvant endocrine therapy (NET) was used as a bridge until postponed surgeries resumed. This study sought to determine the impact of NET on the rate of invasive cancer for patients with a diagnosis of DCIS who have a surgical delay compared with those not treated with NET., Methods: Using the National Cancer Database, the study identified women with hormone receptor-positive (HR+) DCIS. The presence of invasion on final pathology was evaluated after stratifying by receipt of NET and by intervals based on time from diagnosis to surgery (≤30, 31-60, 61-90, 91-120, or 121-365 days)., Results: Of 109,990 women identified with HR+ DCIS, 276 (0.3%) underwent NET. The mean duration of NET was 74.4 days. The overall unadjusted rate of invasive cancer was similar between those who received NET ((15.6%) and those who did not (12.3%) (p = 0.10). In the multivariable analysis, neither the use nor the duration of NET were independently associated with invasion, but the trend across time-to-surgery categories demonstrated a higher rate of upgrade to invasive cancer in the no-NET group (p < 0.001), but not in the NET group (p = 0.97)., Conclusions: This analysis of a pre-COVID cohort showed evidence for a protective effect of NET in HR+ DCIS against the development of invasive cancer as the preoperative delay increased, although an appropriately powered prospective trial is needed for a definitive answer., (© 2021.

Purpose: Breast cancer outcomes are impaired by both delays and disparities in treatment. This study was performed to assess their relationship and to provide a tool to predict patient socioeconomic factors associated with risk for delay., Methods: The National Cancer Database was reviewed between 2004 and 2017 for patients with non-metastatic breast cancer managed with upfront surgery. Times to treatment were measured from the date of diagnosis. Patient, tumor, and treatment factors were assessed with attention paid to sociodemographic variables., Results: 514,187 patients remained after exclusions, with 84.3% White, 10.8% Black, 3.7% Asian, and Hispanics comprising 5.6% of the cohort. Medicaid and uninsured patients had longer mean adjusted time to surgery (≥ 46 days) versus private (36.7 days), Medicare (35.9 days), or other governmental insurance (39.8 days). After adjustment, Black race and Hispanic ethnicity were most impactful, adding 6.0 and 6.4 preoperative days, 10.9 and 11.5 days to chemotherapy, 11.1 and 9.1 days to radiation, and 12.5 and 8.9 days to endocrine therapy, respectively. Income, education, and insurance, among other factors, also affected delay. A nomogram, including race and sociodemographic factors, was created to predict the risk of preoperative delay., Conclusion:  Significant disparities exist in timeliness of care for factors, including but not limited to, race and ethnicity. Although exact causes cannot be discerned, these data indicate population subsets whose intervals of care risk being longer than those specified by national quality standards. The nomogram created here may help direct resources to those at highest risk of incurring a treatment delay., (© 2021.

Background: The COVID crisis hit during the interview season for the Complex General Surgical Oncology (CGSO) fellowship. With minimal time to adapt, all programs transitioned to virtual interviews. Here we describe the experience of both program directors (PDs) and candidates with virtual interviews, and provide guidelines for implementation based on the results., Methods: Surveys regarding interview day specifics and perceptions were created for CGSO fellowship PDs and candidates. They were distributed at the conclusion of the season, prior to match., Results: Thirty (94%) PDs and 64 (79%) candidates responded. Eighty-three% of PDs and 79% of candidates agreed or strongly agreed that they felt comfortable creating a rank list. If given the choice, 60% of PDs and 45% of candidates would choose virtual interviews over in-person interviews. The majority of candidates found PD overviews, fellows only sessions and pre-interview materials helpful., Conclusion: Overall, the majority of PDs and candidates felt comfortable creating a rank list; however, more PDs preferred virtual interviews for the future. Our results also confirm key components of a virtual interview day., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Purpose: LGBTQ+ individuals experience multiple challenges receiving quality care at the end of life, such as lack of confidence in the healthcare system to address their needs and lack of knowledge about advance care planning. Important gaps remain about the needs of LGBTQ+ individuals in the provider-patient relationship and how critical discussions about the end of life occur or do not occur in that relationship. The purpose of this study is to explore patients' narratives of their relationship with their provider and their experiences discussing end-of-life care with their providers, among patients who do and do not identify as LGBTQ+., Methods: Twenty-nine attendants of an event devoted to LGBTQ+ health, 15 of which identified as LGBTQ+, completed an altered version of the CAHPS® Patient Narrative Elicitation Protocol. We used inductive content analysis to qualitatively analyze the data., Results: Respondents described wanting to be heard, finding safety and trust, and valuing competency in their relationship with their provider. Respondents who identified as LGBTQ+ additionally 1) valued providers who avoided making assumptions, 2) looked for cues of safety to indicate they would be accepted by the provider, and 3) sought providers competent in LGBTQ+ care needs. Few respondents had discussed end-of-life care with their provider, although some assumed that their provider may or may not be able to meet their needs based on aspects of their provider-patient relationship., Conclusions: Strengthening patient-provider relationships may help improve the care of LGBTQ+ populations, particularly for the end of life.

Purpose: Performance status (PS) is a subjective assessment of patients' overall health. Quantification of physical activity using a wearable tracker (Fitbit Charge [FC]) may provide an objective measure of patient's overall PS and treatment tolerance., Materials and Methods: Patients with colorectal cancer were prospectively enrolled into two cohorts (medical and surgical) and asked to wear FC for 4 days at baseline (start of new chemotherapy [± 4 weeks] or prior to curative resection) and follow-up (4 weeks [± 2 weeks] after initial assessment in medical and postoperative discharge in surgical cohort). Primary end point was feasibility, defined as 75% of patients wearing FC for at least 12 hours/d, 3 of 4 assigned days. Mean steps per day (SPD) were correlated with toxicities of interest (postoperative complication or ≥ grade 3 toxicity). A cutoff of 5,000 SPD was selected to compare outcomes., Results: Eighty patients were accrued over 3 years with 55% males and a median age of 59.5 years. Feasibility end point was met with 68 patients (85%) wearing FC more than predefined duration and majority (91%) finding its use acceptable. The mean SPD count for patients with PS 0 was 6,313, and for those with PS 1, it was 2,925 (122 and 54 active minutes, respectively) ( P = .0003). Occurrence of toxicity of interest was lower among patients with SPD > 5,000 (7 of 33, 21%) compared with those with SPD < 5,000 (14 of 43, 32%), although not significant ( P = .31)., Conclusion: Assessment of physical activity with FC is feasible in patients with colorectal cancer and well-accepted. SPD may serve as an adjunct to PS assessment and a possible tool to help predict toxicities, regardless of type of therapy. Future studies incorporating FC can standardize patient assessment and help identify vulnerable population.

The coronavirus crisis hit at the beginning of the Complex General Surgical Oncology Fellowship (CGSO) and Breast Oncology Fellowship interview cycles. Within 2 weeks, nearly all programs, including ours, switched to a virtual platform for the remainder of the season. Given that social distancing will remain in place for the foreseeable future, it is possible that all residency and fellowship interviews will need to be conducted virtually. Our methods and shared experience can assist other programs faced with this task for their upcoming interview cycle. We recommend using a virtual meeting platform in which staff have the most comfort; we chose Zoom as our platform. Information on the program traditionally included in the welcome packet, research opportunities, details on the institution, hospital and staff, and detailed interview instructions were distributed prior to the interview day. A virtual "happy hour" was conducted to provide an opportunity for candidates and current trainees to interact. Our virtual interview day schedule mimicked our traditional in person interview day, and we always had a back-up plan for completing the interview if the virtual platform became unstable. While many programs would not choose to perform virtual interviews, we felt that by conducting them in the methods we describe, we were able to closely replicate our traditional interview day and appreciate the candidacy of the applicants., (Copyright © 2020 Association of Program Directors in Surgery.

Importance: Most states have adopted the routine use of a prescription drug monitoring program (PDMP) to curb overprescribing of opioids. The American College of Surgeons promotes the use of these programs as a "guiding principle to curb the opioid epidemic." However, there is a paucity of data on the effects of the use of these programs for surgical patient populations., Objective: To determine the association of the mandatory use of a PDMP with the opioid prescribing practices for patients undergoing general surgery., Design, Setting, and Participants: A prospective observational cohort study was conducted at an academic hospital in New Hampshire among 1057 patients undergoing representative elective general surgical procedures from July 1, 2016, to June 30, 2017., Exposures: New state legislation mandated the use of a PDMP and opioid risk-assessment tool for all patients receiving an outpatient opioid prescription in New Hampshire beginning January 1, 2017. The electronic medical prescribing system was modified to facilitate and support compliance with the new requirements., Main Outcomes and Measures: Change in opioid prescribing practices after January 1, 2017, and time to complete PDMP requirements., Results: Among the 1057 patients (569 women [53.8%] and 488 men [46.2%]; mean [SD] age, 56.8 [15.4] years), the percentage of patients prescribed opioids after surgery did not decrease significantly (429 of 536 [80.0%] before the new requirements vs 401 of 521 [77.0%] after the requirements; P = .29). The mean number of opioid pills prescribed decreased from 30.8 to 24.0 (22.1%) in the 6 months prior to the mandatory PDMP requirement; the rate of decrease was actually less (from 22.8 to 21.9 pills [3.9%]) in the 6 months after the legislation. These new requirements did not identify any high-risk patients who subsequently were not prescribed opioids. The query and opioid abuse risk calculator together took a median time of 7 minutes (range, 2-17 minutes) to complete., Conclusions and Relevance: A mandatory PDMP query requirement was not significantly associated with the overall rate of opioid prescribing or the mean number of pills prescribed for patients undergoing general surgical procedures. In no cases was a high-risk patient identified, leading to avoidance of an opioid prescription. A PDMP can be a useful adjunct in certain settings, but this study found that it did not have the intended effect in a population undergoing elective surgical procedures. Legislative efforts to mandate PDMP use should be targeted to populations in which benefit can be demonstrated.

Background: Surgery for anorectal diseases is thought to cause significant pain postoperatively. There is little known regarding standardized opioid-prescribing trends and patient use following surgery for anorectal diseases. We aimed to evaluate and analyze opioid-prescribing trends and patient use for outpatient anorectal operations., Materials and Methods: All patients who underwent outpatient anorectal surgery performed over a 1-y period at a single institution were eligible. Procedures included hemorrhoidectomy, anal fistula repair/seton, anal fissure treatment with sphincterotomy, and transanal excision of rectal tumors. Demographic, operative, and postoperative data were obtained. Patients were given a survey to determine postoperative pain control with opioid and non-narcotic analgesia use; respondents were included in analysis., Results: Forty-two outpatient anorectal surgery patients were included: 13 had hemorrhoidectomy, 22 had anal fistula repair/seton, one had sphincterotomy, and six had transanal excisions. All patients had multimodality treatment with either an anal block and/or postoperative nonopioid analgesics. Ninety percent were prescribed opioids postoperatively with a median of 20 pills (range: 0-120 pills). Forty-three percent (18/42) did not fill their prescription. For those who used opioids, the median number of pills taken was four. Eighty percent of pills prescribed were not used. One patient required a refill. Greater than 60% of respondents reported good to excellent pain control on a five-point scale., Conclusions: Most patients had adequate pain control after anorectal surgery with little to no use of opioids and that more than 80% of opioid pills prescribed were not consumed. We intend to standardize our prescribing opioid quantities for outpatient anorectal operations to reflect this reduced use., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: There is a paucity of data to inform appropriate opioid prescribing for patients who are discharged after a hospital admission for a surgical procedure., Study Design: We studied 333 inpatients discharged to home after bariatric, benign foregut, liver, pancreas, ventral hernia, and colon surgery. Chronic opioid users or patients who had complications were excluded. Home opioid usage was quantified in 90% of the remaining patients by questionnaires and phone surveys., Results: Eighty-five percent of patients were prescribed an opioid and 38% of prescribed opioid pills were taken. Fifteen opioid pills satisfied the opioid needs of 88% of patients discharged on postoperative day (POD) 1. For patients discharged after POD 1, in multivariate analysis, the number of opioid pills used at home was associated with the number taken the day before discharge (p < 0.0001) and patient age (p = 0.006), but not the type of surgery. Forty-one percent of patients took no opioids the day before discharge, 33% took 1 to 3, and 26% took more than 4 pills. Eighty-five percent of patients' home opioid requirements would be satisfied using the following guideline: if no opioid pills are taken the day before discharge, no prescription is needed; if 1 to 3 opioid pills are taken the day before discharge, then a prescription for 15 opioid pills is given at discharge; and if 4 or more pills are taken the day before discharge, then a prescription for 30 opioid pills is given at discharge. If these guidelines were used, the number of opioid pills prescribed would decrease by 40%., Conclusions: For patients admitted after surgical procedures, post-discharge opioid use is best predicted by usage the day before discharge. Use of this guideline could decrease opioid prescriptions substantially and effectively treat patients' pain., (Copyright © 2017 American College of Surgeons. Published by Elsevier Inc.

Objective: The aim of this study was to determine whether an educational intervention was sufficient to decrease opioid prescribing after general surgical operations., Summary of Background Data: We recently analyzed opioid prescription and use for 5 common outpatient operations at our institution: partial mastectomy (PM), PM with sentinel lymph node biopsy (PM SLNB), laparoscopic cholecystectomy (LC), laparoscopic inguinal hernia repair (LIH), and open inguinal hernia repair (IH). We found that opioids were over-prescribed. We formulated guidelines for opioid prescribing that would halve the number of pills prescribed and also satisfy 80% of patients' opioid requirements., Methods: We discussed our findings and opioid-prescribing guidelines with surgeons at our institution. We recommended that surgeons encourage patients to use a nonsteroidal anti-inflammatory drug (NSAID) and acetaminophen before using opioids. We then evaluated opioid prescriptions and use in 246 subsequent patients undergoing these same operations., Results: The mean number of opioid pills prescribed for each operation markedly decreased: PM 19.8 versus 5.1; PM SLNB 23.7 versus 9.6; LC 35.2 versus 19.4; LIH 33.8 versus 19.3, and IH 33.2 versus 18.3; all P < 0.0003. The total number of pills prescribed decreased by 53% when compared with the number that would have been prescribed before the educational intervention. Only 1 patient (0.4%) required a refill opioid prescription. Eighty-five percent of patients used either a NSAID or acetaminophen., Conclusions: By defining postoperative opioid requirements through patient surveys and disseminating operation-specific guidelines for opioid prescribing to surgeons, we were able to decrease the number of opioids initially prescribed by more than half. Decreased initial opioid prescriptions did not result in increased opioid refill prescriptions.

Background: Complicated diverticulitis is associated with a postoperative mortality rate of 20%. We hypothesized that age ≥80 was an independent risk factor for mortality after Hartmann's procedure for diverticular disease when controlling for baseline comorbidities., Methods: Patients who underwent an urgent or emergent Hartmann's procedure (Current Procedural Terminology codes 44143 and 44206) for diverticular disease (International Classification of Diseases-9:562.xx) were identified using the American College of Surgeons National Surgical Quality Improvement Project 2005-2013 user file. Using propensity score matching to control for baseline comorbidities, a group of patients ≥80 years old was matched to a group of those <80 years old. Univariate and multivariable logistic regression were performed. A P value <0.05 was considered statistically significant with a confidence interval (CI) of 95%., Results: From a total of 2986 patients, 464 patients (15.5%) were ≥80 years old. Two groups of 284 patients in each study arm were matched using propensity-matching. The mean age of the ≥80 group and <80 group was 84.4 ± 3.3 versus 63.77 ± 911.8; P < 0.0001, respectively. There was no statistical difference in baseline comorbidities or operative time between the groups. There was a significant difference in mortality with 19% and 9.2% in the >80 group versus <80 groups, respectively (P = 0.001). Factors associated with mortality included ascites (odds ratio [OR] 4.95, confidence interval [CI] 1.64-14.93, P = 0.005), previous cardiac surgery (OR 3.68, CI 1.46-9.26, P = 0.006), partially dependent or fully dependent functional status (OR 2.51, CI 1.12-5.56, P = 0.02), albumin <3 (OR 2.49, CI 1.18-5.29, P = 0.01), and American Society of Anesthesiologist class >3 (OR 2.10, CI 1.10-4.46, P = 0.05)., Conclusions: Octogenarians presenting with complicated diverticulitis requiring an emergent Hartmann's procedure have a higher mortality rate compared to those <80, even after controlling for baseline comorbidities., Study Type: This is a retrospective, descriptive study., (Copyright © 2017 Elsevier Inc.

Purpose: The effect of pre-operative MRI on the in-breast tumor recurrence rate (IBTR) of patients undergoing breast-conservation treatment (BCT) remains uncertain. We began to routinely perform pre-operative MRI in 2006. Our goal was to determine the effect of pre-operative MRI on IBTR., Methods: Retrospective review of a prospective database of all patients undergoing BCT (n = 1396) from 2000 to 2010. IBTR were calculated using Kaplan-Meier estimates., Results: 664 (47.6%) patients underwent pre-operative MRI. The use of MRI increased from 13.9% in 2000-2005 to 80.7% in 2006-2010. Ten percent of patients who underwent MRI were found to have an additional ipsilateral cancer, with a mean diameter of 1.6 cm. The IBTR for patients with and without MRI were 4% vs. 8% at 8 years (p = 0.04). In multivariate analysis, radiation therapy and endocrine therapy were associated with decreased IBTR, but MRI was not (RR 0.77 (0.45-1.28)). For 1030 patients with invasive cancer, the IBTR at 8 years with and without MRI was 4.2% vs. 7.3% (p = 0.28). For 366 DCIS patients with and without MRI, the IBTR was 3.6% vs. 10.9% (p = 0.06). In the subgroup of DCIS patients who did not receive radiation, the IBTR with and without MRI was 0% vs. 18.2% (p = 0.08). Patients with an additional cancer found by MRI had a higher IBTR at 8 years (10.1% vs. 3.3%, p = 0.02)., Conclusions: In a study analyzing BCT patients from one time period who rarely had a pre-operative MRI and a subsequent time period where most patients had MRI, the use of MRI was associated with a decrease in the IBTR on univariate, but not multivariate analysis. Patients who had additional cancers detected had a significantly higher IBTR.

Objective: To examine opioid prescribing patterns after general surgery procedures and to estimate an ideal number of pills to prescribe., Background: Diversion of prescription opioids is a major contributor to the rising mortality from opioid overdoses. Data to inform surgeons on the optimal dose of opioids to prescribe after common general surgical procedures is lacking., Methods: We evaluated 642 patients undergoing 5 outpatient procedures: partial mastectomy (PM), partial mastectomy with sentinel lymph node biopsy (PM SLNB), laparoscopic cholecystectomy (LC), laparoscopic inguinal hernia repair (LIH), and open inguinal hernia repair (IH). Postoperative opioid prescriptions and refill data were tabulated. A phone survey was conducted to determine the number of opioid pills taken., Results: There was a wide variation in the number of opioid pills prescribed to patients undergoing the same operation. The median number (and range) prescribed were: PM 20 (0-50), PM SLNB 20 (0-60), LC 30 (0-100), LIH 30 (15-70), and IH 30 (15-120). Only 28% of the prescribed pills were taken. This percentage varied by operation: PM 15%, PM SLNB 25%, LC 33%, LIH 15%, and IH 31%. Less than 2% of patients obtained refills.We identified the number of pills that would fully supply the opioid needs of 80% of patients undergoing each operation: PM 5, PM SLNB 10, LC 15, LIH 15, and IH 15. If this number were prescribed, the number of opioid initially prescribed would be 43% of the actual number prescribed., Conclusions: There is wide variability in opioid prescriptions for common general surgery procedures. In many cases excess pills are prescribed. Using our ideal number, surgeons can adequately treat postoperative pain and markedly decrease the number of opioids prescribed.

Background: Postoperative infections are a costly and morbid complication. The introduction of perioperative infection prevention bundles have decreased surgical site infections (SSIs) in patients undergoing colorectal and pancreatic surgery., Aim: The purpose of this study was to determine if the implementation of a perioperative bundle would reduce postoperative infectious complications in patients undergoing hepatic surgery., Methods: An evidence-based, low cost, perioperative infection bundle was created, and a retrospective review of a prospectively maintained database was performed on 163 consecutive patients undergoing hepatic surgery. Patient characteristics, operative details, outcomes, and complications were reviewed, and differences pre- and post-bundle were assessed with univariate and multivariate analyses., Results: A total of 113 patients received standard infection prophylaxis, while 50 received the perioperative bundle. Twenty-five patients had infections (16 deep abscesses, 3 superficial SSIs, 4 urinary tract infections, 1 pneumonia, 1 bacteremia). The overall infection rate decreased from 20.4 % (23/133) pre-bundle to 4 % (2/50) post-bundle. The SSI rate also decreased from 15 % (17/113) to 4 % (2/50). Univariate analysis showed that institution of the bundle was associated with a lower overall infection rate (p = 0.008), lower SSI rate (p = 0.06), and lower overall complication rate (p = 0.04). Multivariate analysis confirmed that the use of the bundle was independently associated with a lower infection (p = 0.008) and SSI (p = 0.05) rate. The primary length of stay (LOS) and LOS for 60 days postoperatively both significantly decreased post-bundle (from median of 5-4 days, p ≤ 0.001; 6-4 days, p ≤ 0.001)., Conclusions: Implementation of a perioperative infection prevention bundle significantly decreased overall infections, SSIs, and postoperative LOS in patients undergoing hepatic surgery.
