Compliance with Evidence-Based Guidelines in Acute Pancreatitis: an Audit of Practices in University of Toronto Hospitals.

Despite existing evidence-based practice guidelines for the management of acute pancreatitis, clinical compliance with recommendations is poor. We conducted a retrospective review of 248 patients admitted between 2010 and 2012 with acute pancreatitis at eight University of Toronto affiliated hospitals. We included all patients admitted to ICU (52) and 25 ward patients from each site (196). Management was compared with the most current evidence used in the Best Practice in General Surgery Management of Acute Pancreatitis Guideline. Fifty-six patients (22.6 %) had only serum lipase tested for biochemical diagnosis. Admission ultrasound was performed in 174 (70.2 %) patients, with 69 (27.8 %) undergoing ultrasound and CT. Of non-ICU patients, 158 (80.6 %) were maintained nil per os, and only 18 (34.6 %) ICU patients received enteral nutrition, commencing an average 7.5 days post-admission. Fifty (25.5 %) non-ICU patients and 25 (48.1 %) ICU patients received prophylactic antibiotics. Only 24 patients (22.6 %) with gallstone pancreatitis underwent index admission cholecystectomy. ERCP with sphincterotomy was under-utilized among patients with biliary obstruction (16 [31 %]) and candidates for prophylactic sphincterotomy (18 [22 %]). Discrepancies exist between the most current evidence and clinical practice within the University of Toronto hospitals. A guideline, knowledge translation strategy, and assessment of barriers to clinical uptake are required to change current clinical practice.

Compliance with a massive transfusion protocol (MTP) impacts patient outcome.

BACKGROUND: About 5% of civilian trauma requires massive transfusion. Protocolized resuscitation with blood products to achieve high plasma:RBC ratio has been advocated to improve survival. Our objectives were to measure compliance to our institutional MTP, to identify quality assurance activities that could improve protocol compliance and to determine if protocol compliance was related to patient outcome. METHODS: The investigators determined 13 compliance criteria based upon our institutional protocol. We measured compliance in 72 consecutive MTP activations between January 2010 and September 2011 at a Level I trauma centre. Data elements were retrospectively retrieved from blood bank, trauma registry and clinical records. Patients were stratified into three groups based on compliance level, and mortality differences were compared. RESULTS: Average compliance for the cohort (n=72) was 66%. The most common cause of non-compliance was failure to send a complete haemorrhage panel from the trauma bay (96%). Failure to monitoring blood work every 30min occurred in 89% of cases. Delay in activation and deactivation occurred in 50% and 50% respectively. Non-compliance to protocol-based administration of blood products happened in 47%. The cohort was stratified into three groups based on compliance, A: <60%, B: 60-80% and C: >80% (low, moderate and high compliance groups). There was no statistical significance with regard to median age, median ISS, ED SBP, ED GCS and AIS of the head/spine, chest and abdomen. The mortality rates in each group were 62%, 50% and 10% in the low, moderate and high compliance groups respectively. Mortality differences were compared using adjusted logistic regression. The OR for mortality between Groups A and B=1.1 [95% CI 0.258-4.687 (P=0.899)] while the OR for mortality between Groups C and B=0.02 [95% CI <0.001-0.855 (P=0.041)]. CONCLUSIONS: Measures should be directed towards provider and system factors to improve compliance. In this study, there was an association between survival and higher level of compliance.

Epidemiology of Acinetobacter spp.-associated healthcare infections and colonization among children at a tertiary-care hospital in Saudi Arabia: a 6-year retrospective cohort study.

A retrospective cohort study was conducted among hospitalized children less than 12 years of age who had Acinetobacter spp. isolated from ≥1 cultures between October 2001 and December 2007 at King Abdulaziz Medical City in Riyadh, Saudi Arabia. Children with multidrug-resistant (MDR) Acinetobacter spp. healthcare-associated infections (HAIs) were compared to children with antimicrobial-susceptible Acinetobacter spp. HAIs and to children colonized with Acinetobacter. Children with MDR Acinetobacter spp. HAIs were older (p = 0.01), more likely to be admitted to an intensive care unit (ICU) (p = 0.06), and had a higher mortality rate (p = 0.02) than colonized children. Children with MDR Acinetobacter spp. HAIs were older than children with antimicrobial-susceptible Acinetobacter spp. HAIs (p = 0.0004), but their mortality rates were similar. Among children with MDR Acinetobacter spp. HAIs, burn injuries were the most common underlying illness. HAIs caused by MDR or susceptible Acinetobacter spp. occurred after prolonged hospitalization, suggesting nosocomial acquisition. Patients infected with MDR Acinetobacter spp. frequently received inappropriate empiric therapy (73.9 %). Further studies are needed in order to identify effective strategies to prevent nosocomial transmission and effective ways of improving patient outcomes.

Follow-up of HIV western blot indeterminate results.

Indeterminate results obtained with the Western blot (WB) confirmatory test on HIV enzyme immunoassay (EIA)-positive samples, constituted 15.6% (444/2849) over a 2.5-year period at the referral laboratory for the Western region at the King Fahd General Hospital, Jeddah. Two hundred and fourteen WB-indeterminate samples were followed up by repeat WB testing of subsequent samples from the same patients over a 3-12 month period. One hundred and forty-two samples (66.4%) gave negative results. Sixty-five samples (30%) remained indeterminate. Only seven samples (3.3%) not initially meeting WHO criteria for positivity turned clear-cut positive, with high EIA readings on follow-up. It was discovered initally that a significant proportion of indeterminates was due to low-grade cross-contamination between samples as a result of aerosol backflow during aspiration in the washing procedure. This was eliminated by rinsing the lines between samples, separating samples with high EIA from those with low EIA, and rerunning indeterminate samples. A reduction of indeterminates from 21% to 8.5% subsequently followed. After this improvement, most of the samples that remained indeterminate had low EIA readings, and few bands of mainly anti-gag (p55, p24 or p18) or anti-pol (p51) antibodies, while the few turning positive all had anti-gp160, in addition to anti-p24 or p55. Interestingly, over the last year and a half of the study, 1.4% of the total samples (21/1506) had repeatedly high EIA readings but were negative by WB. In addition, 16 samples (1.1%) were positive for HIV-2. A separate computer-based system for the storage of data was very helpful in ascertaining proper follow-up of indeterminate WB results.
