In the United States, influenza and pneumonia account significantly to emergency room use and hospitalization of adults >65 y. The Centers for Disease Control and Prevention recommends use of the annual influenza vaccine and 2 pneumococcal vaccines for older adults to decrease risks of morbidity and mortality. However, actual vaccine up-take is estimated at 61.3% for pneumococcal vaccines and 65% for influenza vaccine in the 2013-2014 season. Vaccine up-take is affected by multiple socio-cultural and economic factors including general healthcare access and utilization, social networks and norms, communication with health providers and health information sources, as well as perceptions related to vaccines and targeted diseases. In this study, 8 focus group discussions (total N = 48) were conducted with adults 65+ years living in urban and suburban communities in the Detroit Metropolitan Area. The research objective was to increase understanding of barriers and facilitators to vaccine up-take in this age cohort within the context of general healthcare availability and accessibility, social networks, information sources, and personal perceptions of diseases and vaccines. The data suggest the need to integrate broader health care service experiences, concepts of knowledge of one's own well-being and vulnerabilities, and self-advocacy as factors associated with older adults' vaccine-use decisions. These data also support recognition of multiple levels of vaccine acceptance which can be disease specific. Implications include potential for increasing vaccine up-take through general improvement in health care delivery and services, as well as specific vaccine-focused patient and provider education programs.

Objective:Antimicrobial stewardship programs (ASPs) are effective in developed countries. In this study, we assessed the effectiveness of an infectious disease (ID) physician–driven post-prescription review and feedback as an ASP strategy in India, a low middle-income country (LMIC).Design and setting:This prospective cohort study was carried out for 18 months in 2 intensive care units of a tertiary-care hospital, consisting of 3 phases: baseline, intervention, and follow up. Each phase spanned 6 months.Participants:Patients aged ≥15 years receiving 48 hours of study antibiotics were recruited for the study.Methods:During the intervention phase, an ID physician reviewed the included cases and gave alternate recommendations if the antibiotic use was inappropriate. Acceptance of the recommendations was measured after 48 hours. The primary outcome of the study was days of therapy (DOT) per 1,000 study patient days (PD).Results:Overall, 401 patients were recruited in the baseline phase, 381 patients were recruited in the intervention phase, and 379 patients were recruited in the follow-up phase. Antimicrobial use decreased from 831.5 during the baseline phase to 717 DOT per 1,000 PD in the intervention phase (P < .0001). The effect was sustained in the follow-up phase (713.6 DOT per 1,000 PD). De-escalation according to culture susceptibility improved significantly in the intervention phase versus the baseline phase (42.7% vs 23.6%; P < .0001). Overall, 73.3% of antibiotic prescriptions were inappropriate. Recommendations by the ID team were accepted in 60.7% of the cases.Conclusion:The ID physician–driven implementation of an ASP was successful in reducing antibiotic utilization in an acute-care setting in India.

Objective: To assess the impact of antimicrobial stewardship programs (ASPs) in adult medical–surgical intensive care units (MS-ICUs) in Latin America. Design: Quasi-experimental prospective with continuous time series. Setting: The study included 77 MS-ICUs in 9 Latin American countries. Patients: Adult patients admitted to an MS-ICU for at least 24 hours were included in the study. Methods: This multicenter study was conducted over 12 months. To evaluate the ASPs, representatives from all MS-ICUs performed a self-assessment survey (0–100 scale) at the beginning and end of the study. The impact of each ASP was evaluated monthly using the following measures: antimicrobial consumption, appropriateness of antimicrobial treatments, crude mortality, and multidrug-resistant microorganisms in healthcare-associated infections (MDRO-HAIs). Using final stewardship program quality self-assessment scores, MS-ICUs were stratified and compared among 3 groups: ≤25th percentile, >25th to <75th percentile, and ≥75th percentile. Results: In total, 77 MS-ICU from 9 Latin American countries completed the study. Twenty MS-ICUs reached at least the 75th percentile at the end of the study in comparison with the same number who remain within the 25th percentile (score, 76.1 ± 7.5 vs 28.0 ± 7.3; P < .0001). Several indicators performed better in the MS-ICUs in the 75th versus 25th percentiles: antimicrobial consumption (143.4 vs 159.4 DDD per 100 patient days; P < .0001), adherence to clinical guidelines (92.5% vs 59.3%; P < .0001), validation of prescription by pharmacist (72.0% vs 58.0%; P < .0001), crude mortality (15.9% vs 17.7%; P < .0001), and MDRO-HAIs (9.45 vs 10.96 cases per 1,000 patient days; P = .004). Conclusion: MS-ICUs with more comprehensive ASPs showed significant improvement in antimicrobial utilization.
