RESUMO
BACKGROUND: Antibiotics are commonly prescribed to patients as they leave the hospital. We aimed to create a comprehensive metric to characterize antibiotic overuse after discharge among hospitalized patients treated for pneumonia or urinary tract infection (UTI), and to determine whether overuse varied across hospitals and conditions. METHODS: In a retrospective cohort study of hospitalized patients treated for pneumonia or UTI in 46 hospitals between 1 July 2017-30 July 2019, we quantified the proportion of patients discharged with antibiotic overuse, defined as unnecessary antibiotic use, excess antibiotic duration, or suboptimal fluoroquinolone use. Using linear regression, we assessed hospital-level associations between antibiotic overuse after discharge in patients treated for pneumonia versus a UTI. RESULTS: Of 21 825 patients treated for infection (12â¯445 with pneumonia; 9380 with a UTI), nearly half (49.1%) had antibiotic overuse after discharge (56.9% with pneumonia; 38.7% with a UTI). For pneumonia, 63.1% of overuse days after discharge were due to excess duration; for UTIs, 43.9% were due to treatment of asymptomatic bacteriuria. The percentage of patients discharged with antibiotic overuse varied 5-fold among hospitals (from 15.9% [95% confidence interval, 8.7%-24.6%] to 80.6% [95% confidence interval, 69.4%-88.1%]) and was strongly correlated between conditions (regression coefficient = 0.85; P < .001). CONCLUSIONS: Antibiotic overuse after discharge was common and varied widely between hospitals. Antibiotic overuse after discharge was associated between conditions, suggesting that the prescribing culture, physician behavior, or organizational processes contribute to overprescribing at discharge. Multifaceted efforts focusing on all 3 types of overuse and multiple conditions should be considered to improve antibiotic prescribing at discharge.

IMPORTANCE: Antibiotic therapy is the cornerstone of medical management for community-acquired pneumonia. OBJECTIVE: To assess the associations between 3 key aspects of antibiotic therapy (optimal time to antibiotic initiation, initial antibiotic selection, and criteria for the transition from intravenous to oral therapy) and short-term mortality in adults hospitalized with community-acquired pneumonia. EVIDENCE REVIEW: Bibliographic databases of MEDLINE, EMBASE, and the Cochrane Collaboration were searched for studies of adults hospitalized with radiographically confirmed community-acquired pneumonia published from January 1, 1995, until November 5, 2015. FINDINGS: Twenty studies (17 observational and 3 randomized trials) met eligibility criteria. Among 8 observational studies identified, the 4 largest (study populations of 2878 to 1,170,022) found that antibiotic initiation within 4 to 8 hours of hospital arrival was associated with relative reductions of 5% to 43% in mortality; the 4 smallest studies (study populations of 451 to 2076) found no associations between the timing of antibiotic initiation and mortality. One cluster randomized trial (n = 1737) demonstrated noninferiority of ß-lactam monotherapy (n = 506) vs ß-lactam plus macrolide combination therapy (n = 566), with an absolute adjusted difference of 2.5% (90% CI, -0.6% to 5.2%) in 90-day mortality favoring ß-lactam monotherapy. A second randomized trial (n = 580) failed to demonstrate noninferiority of ß-lactam monotherapy vs ß-lactam plus macrolide combination therapy, with an absolute difference of 7.6% (1-sided 90% CI upper limit, 13.0%) in attainment of clinical stability on hospital day 7 favoring ß-lactam plus macrolide combination therapy. Six of 8 observational studies (study populations of 1188 to 24,780) found that ß-lactam plus macrolide combination therapy was associated with relative reductions of 26% to 68% in short-term mortality and all 3 observational studies (study populations of 2068 to 24,780) reported that fluoroquinolone monotherapy was associated with relative reductions of 30% to 43% in mortality compared with ß-lactam monotherapy. One randomized trial (n = 302) reported significantly reduced hospital length of stay (absolute difference, 1.9 days; 95% CI, 0.6 to 3.2 days), but no differences in treatment failure when objective clinical criteria were used to decide when to transition patients from intravenous to oral therapy. CONCLUSIONS AND RELEVANCE: In adults hospitalized with community-acquired pneumonia, antibiotic therapy consisting of ß-lactam plus macrolide combination therapy or fluoroquinolone monotherapy initiated within 4 to 8 hours of hospital arrival was associated with lower adjusted short-term mortality, supported predominantly by low-quality observational studies. One randomized trial supports the use of objective clinical criteria to guide the transition from intravenous to oral antibiotic therapy.

OBJECTIVE: To assess association of pharmacist gender with acceptance of antibiotic stewardship recommendations. DESIGN: A retrospective evaluation of the Reducing Overuse of Antibiotics at Discharge (ROAD) Home intervention. SETTING: The study was conducted from May to October 2019 in a single academic medical center. PARTICIPANTS: The study included patients receiving antibiotics on a hospitalist service who were nearing discharge. METHODS: During the intervention, clinical pharmacists (none who had specialist postgraduate infectious disease residency training) reviewed patients on antibiotics and led an antibiotic timeout (ie, structured conversation) prior to discharge to improve discharge antibiotic prescribing. We assessed the association of pharmacist gender with acceptance of timeout recommendations by hospitalists using logistic regression controlling for patient characteristics. RESULTS: Over 6 months, pharmacists conducted 295 timeouts: 158 timeouts (53.6%) were conducted by 12 women, 137 (46.4%) were conducted by 8 men. Pharmacists recommended an antibiotic change in 82 timeouts (27.8%), of which 51 (62.2%) were accepted. Compared to male pharmacists, female pharmacists were less likely to recommend a discharge antibiotic change: 30 (19.0%) of 158 versus 52 (38.0%) of 137 (P < .001). Female pharmacists were also less likely to have a recommendation accepted: 10 (33.3%) of 30 versus 41 (8.8%) of 52 (P < .001). Thus, timeouts conducted by female versus male pharmacists were less likely to result in an antibiotic change: 10 (6.3%) of 158 versus 41 (29.9%) of 137 (P < .001). After adjustments, pharmacist gender remained significantly associated with whether recommended changes were accepted (adjusted odds ratio [aOR], 0.10; 95%confidence interval [CI], 0.03-0.36 for female versus male pharmacists). CONCLUSIONS: Antibiotic stewardship recommendations made by female clinical pharmacists were less likely to be accepted by hospitalists. Gender bias may play a role in the acceptance of clinical pharmacist recommendations, which could affect patient care and outcomes.

BACKGROUND: Antibiotic overuse at hospital discharge is common and harmful; however, methods to improve prescribing during care transitions have been understudied. We aimed to pilot a pharmacist-facilitated antibiotic timeout prior to discharge. METHODS: From May 2019 to October 2019, we conducted a single-center, controlled pilot study of a pharmacist-facilitated antibiotic timeout prior to discharge. The timeout addressed key elements of stewardship (eg, duration) and was designed and implemented using iterative cycles with rapid feedback. We evaluated implementation outcomes related to feasibility, including usability, adherence, and acceptability, using mixed methods. Pre versus postintervention antibiotic use at discharge in intervention versus control groups was assessed using logistic regression models controlling for patient characteristics. RESULTS: Pharmacists conducted 288 antibiotic timeouts. Timeouts were feasible (mean 2.5 minutes per timeout) and acceptable (85% [40/48] of hospitalists believed timeouts improved prescribing). Pharmacists recommended an antibiotic change in 25% (73/288) of timeouts with 70% (51/73) of recommended changes accepted by hospitalists. Barriers to adherence included unanticipated and weekend discharges. Compared to control services, there were no differences in antibiotic use after discharge during the intervention. CONCLUSIONS: A pharmacist-facilitated antibiotic timeout at discharge was feasible and holds promise as a method to improve antibiotic use at discharge.
