Impact of prolonged carbapenem use-focused antimicrobial stewardship on antimicrobial consumption and factors affecting acceptance of recommendations: a quasi-experimental study.

ABSTRACT: This study aimed to assess the impact of a prolonged carbapenem use-focused antimicrobial stewardship program (ASP) on antimicrobial consumption and clinical outcomes and to analyze factors affecting adherence to interventions. Patients prescribed carbapenems for ≥ 2 weeks received intervention. Interrupted time-series analysis was performed to compare antimicrobial consumption before and after intervention. Factors associated with non-adherence to intervention were investigated. Of 273 patients who were eligible for intervention, discontinuation or de-escalation was recommended in 256 (94.1%) and intervention was accepted in 136 (53.1%) patients. Before intervention, carbapenem consumption significantly increased to 1.14 days of therapy (DOT)/1000 patient days (PD)/month (P = 0.018). However, it significantly declined by - 2.01 DOT/1000 PD/month without an increase in other antibiotic consumption (P < 0.001). Factors affecting non-adherence to intervention were younger age (odds ratio [OR] = 0.98; 95% confidence interval [CI] 0.96-1.00), solid organ malignancy (OR = 2.53, 95% CI 1.16-5.50), and pneumonia (OR = 2.59, 95% CI 1.08-6.17). However, ASP intervention was not associated with clinical outcomes such as length of hospital stay or mortality. Prolonged carbapenem prescription-focused ASP significantly reduced carbapenem consumption without adverse outcomes. Non-adherence to interventions was attributed more to prescriber-related factors, such as attitude, than patient-related factors including clinical severity.

Project description:Abstract Background Telehealth-based antimicrobial stewardship programs (TeleASPs) have led to reduced broad-spectrum antimicrobial utilization. Data on factors associated with acceptance of stewardship recommendations are limited. Methods A TeleASP, facilitated by remote infectious disease physicians and local pharmacists, was implemented in 2 community hospitals from February 2018 through July 2020. Variables potentially affecting acceptance of TeleASP recommendations were tracked. Odds ratios of acceptance were determined utilizing multiple logistic regression. Results During the 30-month period, 4863 (91.2%) of the total 5333 recommendations were accepted. Factors associated with a higher odds of acceptance in multivariable analysis were recommendations for antimicrobial dose/frequency adjustment (odds ratio [OR], 2.63; 95% CI, 1.6–4.3) and order for labs/tests (OR, 3.30; 95% CI, 2.1–5.2), while recommendations for antimicrobial de-escalation (OR, 0.75; 95% CI, 0.60–0.95) and antimicrobial discontinuation (OR, 0.57; 95% CI, 0.42–0.76) were associated with lower odds of acceptance. Female physicians were more likely to accept recommendations compared with males (93.1% vs 90.3% acceptance; OR, 1.65; 95% CI, 1.3–2.2). Compared with physicians with <3 years of experience, who had the highest acceptance rate (96.3%), physicians with ≥21 years of experience had the lowest (87.1%; OR, 0.26; 95% CI, 0.15–0.45). Conclusions TeleASP recommendations were accepted at a high rate. Acceptance rates were higher among female physicians, and recommendations to stop or de-escalate antimicrobials led to lower acceptance. Recommendations made to the most experienced physicians were the least accepted, which may be an important factor for stewardship programs to consider in education and intervention efforts. We evaluated variables impacting acceptance of stewardship recommendations at two community hospitals. Recommendations to stop or de-escalate antimicrobials led to lower acceptance Female physicians were more likely to accept recommendations, and recommendations to the most experienced physicians were least accepted.
