Antimicrobial use at a university hospital: appropriate or misused? A qualitative study

OBJECTIVE: To evaluate the quality of antimicrobial drug use in a university hospital medical department (Department of Medicine, University Hospital Rijeka, Croatia) with 279 hospital-beds in wards containing patients from endocrinology, gastroenterology, hematology, clinical immunology, cardiology and coronary care unit, nephrology and pulmonology sections of the hospital. METHODS: The appropriateness of antimicrobial treatment for all in-patients in the Department of Medicine was assessed in a prospective, longitudinal survey carried out during a 21-week period using Kunin's criteria where Categories I and II indicate "appropriate therapy", Categories III and IV indicate major deficiency in the choice or use of antimicrobials. Category V indicates unjustified antimicrobial administration. RESULTS: During the study period, a total of 438 patients were treated with antimicrobials in the Department of Medicine. Of these, 159 (36%) received antimicrobials appropriately (Category I and II), 180 (41%) needed antimicrobials (Category III and IV) but they should have been prescribed differently. The main reason for inappropriate antimicrobial treatment was the wrong choice of antimicrobials (broad-spectrum where a narrow spectrum antibiotic would have been sufficient). In the case of 99 patients (23%) an indication for antimicrobial therapy did not exist (Category V). CONCLUSION: The main reason for suboptimal use of antimicrobials was the over-prescribing of broad-spectrum antimicrobials. This situation should be corrected e.g. by changes in the post-graduate medical teaching program.     

Application of ATC/DDD methodology to evaluate perioperative antimicrobial prophylaxis

Objective To evaluate quality of perioperative antibiotic prophylaxis (PAP) and to calculate the cost per procedure in a Turkish university hospital. Setting A 352-bed teaching hospital in Denizli, Turkey. Method An prospective audit was performed between July and October 2010. All clean, clean-contaminated and contaminated elective surgical procedures in ten surgical wards were recorded. Antimicrobial use was calculated per procedure using the ATC-DDD system. The appropriateness of antibiotic use for each procedure was evaluated according to international guidelines on PAP. In addition, the cost per procedure was calculated. Results Overall, in 577 of the 625 (92.3%) of the studied procedures, PAP was used. PAP was indicated in 12.5% of the group where it was not used, and not indicated in 7.1% of the group where it was used. Unnecessarily prolonged antimicrobial prophylaxis was observed in 56.9% of the procedures, mean duration was 2.6?±?2.7?days. The most frequently used antimicrobials were cefazolin (117.9 DDD/100-operation) and sulbactam/ampicillin (102.2 DDD/100-operation). The timing of the starting dose was appropriate in 545 procedures (94.5%). In the group that received PAP, only 80 (13.7%) of the procedures were found to be fully appropriate and correct. The density of antimicrobial use per operation was 2.8 DDD. The mean cost of the use of prophylactic antimicrobials ?18.6 per procedure. Conclusion The density of antimicrobial use in PAP was found to be very high in our hospital. Antibiotic overuse extended into the postoperative period.     

Advances in pharmacovigilance initiatives surrounding antimicrobial resistance-Indian perspective

ABSTRACT

Introduction: In recent years the development of antimicrobial resistance has been accelerating, the discovery of new antimicrobial agents has slowed substantially in past decades.

Area covered: This review mainly focuses on the problem of antimicrobial resistance(AMR); the various contributor mechanisms, consequences and future of AMR. The review also highlights the irrational use of antimicrobials, improving their usage and problems associated with pharmacovigilance of antimicrobial resistance.

Expert opinion: Pharmacovigilance in the form of surveillance of antibiotic use is being done in 90% of the countries worldwide through the WHONET program developed by WHO. However, the data comes from a limited area of the globe. Data from every part of the world is required, so that there is geographical representation of every region. A major hurdle in quantifying the extent of antimicrobial resistance is the fact that there are several known microbes, that may turn out to be resistant to one or more of the several known antimicrobial agents. The global action plan initiated by WHO, if implemented successfully will definitely reduce AMR and will help in evaluating treatment interventions.     

Safety and effectiveness of thromboprophylaxis use in hospitalized elderly medical patients at a Saudi tertiary care center

IntroductionAppropriate prescribing of thromboprophylaxis according to guidelines’ recommendations can heighten over- or underutilization risk. The study intended to evaluate the safety and effectiveness of appropriate/inappropriate thromboprophylaxis use among hospitalized elderly medical patients.MethodsA retrospective observational cohort study was conducted, including patients who were ≥60 years old, hospitalized for an acute medical illness that required hospitalization in a medical ward for >48 h, and received thromboprophylaxis. Against the American College of Chest Physicians guidelines, the thromboprophylaxis use appropriateness was assessed.ResultsA total of 370 patients met the inclusion criteria, in 71.9% of whom thromboprophylaxis use was appropriate. The mean age of the included patients was 75 years (±9.1), and 72.4% of them were at high risk of venous thromboembolism (VTE), and almost all these patients received appropriate thromboprophylaxis. The occurrence of bleeding was significantly higher in the appropriate use group during hospitalization than the inappropriate use group (11.7% vs. 2.9%, p = 0.009); the majority of these bleeding events were classified as major. There were no differences in VTE events during hospitalization or 90 days all-cause mortality between the two groups.ConclusionThe study demonstrates high prescribers’ compliance with recommendations in high-risk patients. In patients at low risk for VTE, the overutilization of thromboprophylaxis did not increase their bleeding risk. This study suggests that the benefits of thromboprophylaxis in elderly patients, regardless of their VTE risk, may outweigh the risk of bleeding.     

Discontinuation of antimicrobial therapy in adult neutropenic haematology patients: A prospective cohort

ObjectivesAntibiotics for febrile neutropenia (FN) in acute myeloid leukaemia (AML) patients undergoing intensive chemotherapy are usually maintained until neutropenia resolution, because of the risk of uncontrolled sepsis in this vulnerable population. This leads to unnecessarily prolonged antimicrobial therapy.MethodsBased on ECIL-4 recommendations, we modified our management strategy and discontinued antibiotics after a pre-established duration in patients treated for a first episode of FN between August 2014 and October 2017.ResultsAntibiotics were stopped during 62 FN episodes, and maintained in the control group (n = 13). Median age of patients was 54 years. A total of 39 (63%) patients received induction and 23 (37%) consolidation chemotherapy; 36 (58%) patients had fever of unknown origin. Median neutropenia length was 26 days (IQR 24–30). Antibiotics were started at day 9 (IQR 5–13). Most patients received piperacillin-tazobactam (56%) or cefepime (32%). Antimicrobial therapy was longer in the control group than in the policy compliant group, 10 (IQR 7–16) vs. 19 days (IQR 15–23), P = 0.0001. After antibiotics discontinuation, 20% patients experienced fever recurrence, within 5.5 days (IQR 3–7.5). None of these febrile episodes were severe and 80% patients remained afebrile, with neutrophil recovery occurring within 5 days (IQR 2–8.5). Overall, 287 antibiotics days were spared; this represents 49% of all days with antibiotics. No patient had died at day 30 from intervention; six died during late follow-up, two from graft-versus-host disease and four from relapsed or refractory leukaemia.ConclusionsDiscontinuing antibiotics in neutropenic AML patients treated for a first episode of FN is safe, and results in significant antibiotic sparing.     

Antimicrobial stewardship solutions with a smart innovative tool

BackgroundAntimicrobial consumption has been increasing lately. Hence, effective strategies are required to control antimicrobial use and decrease the development of antimicrobial resistance.ObjectiveTo evaluate the impact of the use of a mobile app on the implementation of antimicrobial stewardship program (ASP) interventions.MethodsThis was a longitudinal study conducted at El-Nile Badrawi Hospital in Cairo, Egypt, on inpatients receiving antimicrobials from January 2018 to December 2019. The study included 2 phases: the preimplementation phase, which included a paper-based ASP developed according to the Centers for Disease Control and Prevention Core Elements of Hospital Antibiotic Stewardship Programs 2014, and the mobile app phase where the MEDIcare Pro mobile app was developed and used in ASP intervention implementation. The study outcomes were antimicrobial consumption and cost, length of hospital and intensive care unit (ICU) stay, 30-day mortality rate and readmission rate, and detection of drug-related problems (DRPs).ResultsThe mobile app statistically significantly decreased antimicrobial consumption from 75.1 defined daily dose (DDD)/100 bed-days in the preimplementation phase to 64.65 DDD/100 bed-days in the mobile app phase, with a total cost savings of E£1,237,476. There was a significant reduction in the length of ICU stay, with a mean difference of 1.63 days between the 2 phases, but no significance was detected regarding length of hospital stay or readmission rate. There was a statistically significant decrease in mortality rate from 1.17% in the preimplementation phase to 0.83% in the mobile app phase (P = 0.02). The frequency of DRPs detected by pharmacists statistically significantly increased from 0.54/100 bed-days in the preimplementation phase to 3.23/100 bed-days in the mobile app phase.ConclusionThe use of a mobile app was found to be effective, applicable, and usable in guiding health professionals on rational antimicrobial use.
