Clinical and Economic Benefits of Antimicrobial Stewardship Programs in Hemodialysis Facilities: A Decision Analytic Model.

ABSTRACT: BACKGROUND AND OBJECTIVES:Infections caused by multidrug-resistant organisms and Clostridium difficile are associated with substantial morbidity and mortality as well as excess costs. Antimicrobial exposure is the leading cause for these infections. Approximately 30% of antimicrobial doses administered in outpatient hemodialysis facilities are considered unnecessary. Implementing an antimicrobial stewardship program in outpatient hemodialysis facilities aimed at improving prescribing practices would have important clinical and economic benefits. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS:We developed a decision analytic model of antimicrobial use on the clinical and economic consequences of implementing a nationwide antimicrobial stewardship program in outpatient dialysis facilities. The main outcomes were total antimicrobial use, infections caused by multidrug-resistant organisms and C. difficile, infection-related mortality, and total costs. The analysis considered all patients on outpatient hemodialysis in the United States. The value of implementing antimicrobial stewardship programs, assuming a 20% decrease in unnecessary antimicrobial doses, was calculated as the incremental differences in clinical end points and cost outcomes. Event probabilities, antimicrobial regimens, and health care costs were informed by publicly available sources. RESULTS:On a national level, implementation of antimicrobial stewardship programs was predicted to result in 2182 fewer infections caused by multidrug-resistant organisms and C. difficile (4.8% reduction), 629 fewer infection-related deaths (4.6% reduction), and a cost savings of $106,893,517 (5.0% reduction) per year. The model was most sensitive to clinical parameters as opposed to antimicrobial costs. CONCLUSIONS:The model suggests that implementation of antimicrobial stewardship programs in outpatient dialysis facilities would result in substantial reductions in infections caused by multidrug-resistant organisms and C. difficile, infection-related deaths, and costs.

Project description:The implementation of antimicrobial stewardship programs (ASPs) is a promising strategy to help address the problem of antimicrobial resistance. We sought to determine the efficacy of ASPs and their effect on clinical and economic parameters. We searched PubMed, EMBASE, and Google Scholar looking for studies on the efficacy of ASPs in hospitals. Based on 26 studies (extracted from 24,917 citations) with pre- and postimplementation periods from 6 months to 3 years, the pooled percentage change of total antimicrobial consumption after the implementation of ASPs was -19.1% (95% confidence interval [CI] = -30.1 to -7.5), and the use of restricted antimicrobial agents decreased by -26.6% (95% CI = -52.3 to -0.8). Interestingly, in intensive care units, the decrease in antimicrobial consumption was -39.5% (95% CI = -72.5 to -6.4). The use of broad-spectrum antibiotics (-18.5% [95% CI = -32 to -5.0] for carbapenems and -14.7% [95% CI = -27.7 to -1.7] for glycopeptides), the overall antimicrobial cost (-33.9% [95% CI = -42.0 to -25.9]), and the hospital length of stay (-8.9% [95% CI = -12.8 to -5]) decreased. Among hospital pathogens, the implementation of ASPs was associated with a decrease in infections due to methicillin-resistant Staphylococcus aureus (risk difference [RD] = -0.017 [95% CI = -0.029 to -0.005]), imipenem-resistant Pseudomonas aeruginosa (RD = -0.079 [95% CI = -0.114 to -0.040]), and extended-spectrum beta-lactamase Klebsiella spp. (RD = -0.104 [95% CI = -0.153 to -0.055]). Notably, these improvements were not associated with adverse outcomes, since the all-cause, infection-related 30-day mortality and infection rates were not significantly different after implementation of an ASP (RD = -0.001 [95% CI = -0.009 to 0.006], RD = -0.005 [95% CI = -0.016 to 0.007], and RD = -0.045% [95% CI = -0.241 to 0.150], respectively). Hospital ASPs result in significant decreases in antimicrobial consumption and cost, and the benefit is higher in the critical care setting. Infections due to specific antimicrobial-resistant pathogens and the overall hospital length of stay are improved as well. Future studies should focus on the sustainability of these outcomes and evaluate potential beneficial long-term effects of ASPs in mortality and infection rates.

Project description:Introduction: Antimicrobial resistance (AMR) is a current global health threat and a challenge to the treatment of infectious diseases. The WHO advocates a strategy of antibiotic stewardship programs (ASP) in optimizing antimicrobial use in hospitals. This study aimed at assessing the existence of AMR surveillance and ASP implementation in health facilities in Tanzania in the year following the launch of the National Action Plan (NAP). Methodology: From December 2017 through July 2018, a descriptive cross-sectional study was conducted using a structured questionnaire administered online. A total of 199 health facilities in Tanzania mainland whose contacts was obtained from the Ministry of Health Community Development Gender Elderly and Children (MoHCDGEC) were reached by phone and thereafter, a survey was sent via text or e-mail to focal persons in the corresponding facilities. Results: Only 39 (32.5%) responses from contacted facilities were received and analyzed. Thirty (76.9%) of the facilities were government-owned. Of the 39 respondents surveyed, 13 (35.9%) declared to have implemented some sort of coordinated ASP to promote the rational use of antimicrobials at their facilities. The respondents reported the presence of guidelines for the implementation of ASP at variable proportions, whereas the presence of a committee for Infection Prevention and Control was reported by 27 (69.2%). Twenty-four (61.5%) had a Medical and Therapeutic Committee. Although all 39 (100%) respondents were aware of the presence of AMR in Tanzania, only 26 (66.7%) were aware of the presence of the Tanzanian NAP for AMR. Hospital antibiotic policy document was present in 6 (15.4%) facilities. Only 7 (17.9%) facilities conducted prescription auditing; 9 (23.1%) had a hospital formulary; 14 (35.9%) had standard hospital prescription. 9 (23.1%) had software for data storage about AMR. Only 7 (17.9%) facilities conducted microorganisms' susceptibility tests and kept the record of the microorganism susceptibility testing. Conclusion: Our study found the existence of AMR surveillance activities and ASP implementation in Tanzania, albeit at a low level. The implementation was inconsistent across the surveyed facilities. These data have identified areas of improvement in addressing AMR in Tanzania through the NAP.

Project description:BackgroundInformation about the feasibility, barriers and facilitators of antimicrobial stewardship (AMS) in residential aged care facilities (RACFs) has been scant. Exploring the prevailing perceptions and attitudes of key healthcare providers towards antibiotic prescribing behaviour, antibiotic resistance and AMS in the RACF setting is imperative to guide AMS interventions.MethodsSemi-structured interviews and focus groups were conducted with key RACF healthcare providers until saturation of themes occurred. Participants were recruited using purposive and snowball sampling. The framework approach was applied for data analysis.ResultsA total of 40 nurses, 15 general practitioners (GPs) and 6 pharmacists from 12 RACFs were recruited. Five major themes emerged; perceptions of current antibiotic prescribing behaviour, perceptions of antibiotic resistance, attitude towards and understanding of AMS, perceived barriers to and facilitators of AMS implementation, and feasible AMS interventions. A higher proportion of GPs and pharmacists compared with nurses felt there was over-prescribing of antibiotics in the RACF setting. Antibiotic resistance was generally perceived as an issue for infection control rather than impacting clinical decisions. All key stakeholders were supportive of AMS implementation in RACFs; however, they recognized barriers related to workload and logistical issues. A range of practical AMS interventions were identified, with nursing-based education, aged-care specific antibiotic guidelines and regular antibiotic surveillance deemed most useful and feasible.ConclusionsAreas of antibiotic over-prescribing have been identified from different healthcare providers' perspectives. However, concern about the clinical impact of antibiotic resistance was generally lacking. Importantly, information gathered about feasibility, barriers and facilitators of various AMS interventions will provide important insights to guide development of AMS programs in the RACF setting.
