Institutional-specific smartphone application as a supplemental tool for an antimicrobial stewardship program in 2 large community-based hospitals: Acceptance of physicians and pharmacists

Purpose: Antimicrobial stewardship programs (ASPs) have been a challenge in less resourceful health care settings. Medical smartphone applications (apps) can be accessible tools to support ASPs under such circumstances. A hospital-specific ASP app was prepared and the acceptance and usability of the study ASP app were evaluated by physicians and pharmacists in 2 community-based academic hospitals. Methods: The exploratory survey was conducted 5 months following the implementation of the study ASP app. A questionnaire was developed, and the validity and reliability were analyzed using S-CVI/Ave (scale content validity index/Average) and Cronbach's alpha, respectively. The questionnaire consisted of demographics (3 items), acceptance (9 items), usability (10 items), and barriers (2 items). Descriptive analysis was conducted using a 5-point Likert scale, multiple selections, and free-text responses. Results: Approximately 38.7% of 75 respondents (response rate, 23.5%) used the app. Most scored 4 or higher, indicating that the study ASP app was easy to install (89.7%), use (79.3%), and apply to clinical settings (69.0%). Frequently used contents were dosing (39.6%), the spectrum of activity (7.1%), and intravenous-to-oral conversion (7.1%). Barriers included limited time (38.2%) and insufficient content (20.6%). Users indicated that the study ASP app helped improve their knowledge on treatment guidelines (72.4%), antibiotic use (62.1%), and adverse reactions (69.0%). Conclusion: The study ASP app was well accepted by physicians and pharmacists and it can be useful to supplement ASPs activities in less resourceful hospitals with a large burden of patient care.
