Background Clinical practice guidelines are developed to assist in patient care but the evidence basis for many guidelines has been called into question. Methods We conducted a literature review using PubMed and analyzed the overall quality of evidence and made strength of recommendation behind 8 Institute of Health Care (IHI) guidelines for prevention of central line associated blood stream infection (CLABSI). Quality of evidence was assessed by the American Thoracic Society (ATS) levels of evidence (levels I through III). We also examined data from our intensive care units (ICUs) for evidence of a correlation between guideline compliance and the development of VAP.Results None of the guidelines was graded at level I. Two of the guidelines were graded at level II and the remaining 6 at level III. Despite the lack of evidence, 2 of the guidelines (hand hygiene, sterile gloves) were given a strong recommendation. Chlorhexidine and use of nonfemoral sites were given a moderate recommendation. In our ICUs compliance with the use of chlorhexidine correlated with a reduction in CLABSI (p

Introduction: Increased nursing staffing levels have previously been associated with improved patient outcomes. However, the effects of physician staffing and other clinical care costs on clinical outcomes are unknown.Methods: Databases from the Department of Veterans Affairs were searched for clinical outcome data including 30-day standardized mortality rate (SMR), observed minus expected length of stay (OMELOS) and readmission rate. These were correlated with costs including total, drug, lab, radiology, physician (MD), and registered nurse (RN), other clinical personnel costs and non-direct care costs.Results: Relevant data were obtained from 105 medical centers. Higher total costs correlated with lower intensive care unit (ICU) SMR (r=-0.2779, p

Health care organizations have been using performance measures to compare hospitals. However, it is unclear if compliance with these performance measures results in better healthcare outcomes. We examined compliance with acute myocardial infarction, congestive heart failure, pneumonia and surgical process of care measures with traditional outcome measures including mortality rates, morbidity rates, length of stay and readmission rates using the Veterans Healthcare Administration Quality and Safety report. Disappointingly, increased compliance with the performance measures was not correlated with better outcomes with the single exception of improved mortality with higher rates of compliance with echocardiography. We also evaluated the hospital level of care and found that higher levels of complexity of care correlated with the acute myocardial infarction performance measure, but not with the congestive heart failure, pneumonia, or surgical process of care performance measures. However, level of complexity of care strongly correlated with all cause mortality (p

Previous studies have suggested that an arterial ammonia level greater than 150 mmol/L is highly sensitive for predicting subsequent development of cerebral edema in patients with fulminant liver failure. We performed a prospective cohort study to confirm this relationship. We enrolled 22 consecutive patients who presented to our transplant hepatology service with grade 3-4 encephalopathy associated with fulminant liver failure. All patients underwent placement of an intraparenchymal ICP monitor, and every 12 hourly arterial ammonia levels. The prevalence of intracranial hypertension (IHTN) in our population was 95% (21/22 patients), with 82 discrete episodes recorded. The sensitivity of arterial ammonia levels to predict the onset of IHTN was 62% (95% CI: 40.8 to 79.3) at a cut point of 150 mmol/L. Arterial ammonia levels preceding the first intracranial hypertension event were less than 150 mmol/L in 8 of 21 patients (39%). Fifty nine of 82 episodes of IHTN (73%) occurred when arterial ammonia levels were less than 150 mmol/L. We conclude that the arterial ammonia level is not useful in making decisions regarding management related to cerebral edema in patients with fulminant liver failure. In fact, since almost all our study patients with grade III or IV encephalopathy secondary to fulminant liver failure went on to develop intracranial hypertension, our study supports the contention that all such patients might benefit from ICP monitoring regardless of arterial ammonia levels.

Introduction Prolonged length of labor is associated with increased maternal and neonatal complications. Therefore, great attention has been given to interventions aimed at reducing the length of labor. One such intervention is the peanut ball, a large elongated exercise ball placed between a woman’s legs during labor. Objective The aim of this systematic review and meta-analysis of randomized controlled trials (RCTs) was to assess the effect of the use of peanut ball in reducing length of labor. Study Design Data sources: MEDLINE, EMBASE, Web of Sciences, Scopus, ClinicalTrial.gov, OVID and Cochrane Library were searched from inception until January 2019. Selection criteria: Selection criteria included RCTs of laboring women with singleton gestations in cephalic presentation at term (≥37weeks) who were randomized to either use of peanut ball or control group (no peanut ball). Data Collection and Analysis: Four trials with 648 nulliparous and multiparous women in spontaneous or induced labor were identified and included. 330 women were randomized to the intervention (peanut ball between the knees during labor) and 318 women to the control. Summary measures were reported as mean difference (MD) with 95% of confidence interval (CI) using the random effects model of DerSimonian and Laird. The primary outcome was total length of labor. PROSPERO Registration Number: CRD42018082438 Results Total length of labor was 79 min shorter in the peanut ball group, but this was not significant (MD −79.1 min, 95% CI −204.9, 46.7). Peanut ball use showed trends toward higher incidence of spontaneous vaginal deliveries (RR 1.1, 95% CI 1.0, 1.2) and lower incidence of cesarean deliveries (RR 0.8, 95% CI 0.6, 1.0). Conclusions Peanut ball use was not associated with a significant decrease in total length of labor. Since there were trends toward reductions in length of labor, an increased incidence in spontaneous vaginal deliveries, and lower incidence of cesarean deliveries, more research is needed.
