The vital role of clinical pharmacy services within the hospital at home interdisciplinary team

Abstract Purpose Hospital at home (HaH) program development, spurred by hospital congestion during the COVID-19 pandemic, is moving from a novel idea to a standard of inpatient practice. Understanding pharmacy’s clinical role in the HaH patient care team is exceedingly important as programs across the country continue to develop, implement, and expand. The purpose of this study is to describe how clinical pharmacy services are currently provided for home hospital patients and to explain the vital role of pharmacists within the HaH care team. Description A descriptive study was designed to evaluate pharmacy services provided for home hospital patients from January 1, 2023, to February 28, 2023. Prior to the study period, a focused group of pharmacists routinely active in HaH patient care met to define a standard process for documenting pharmacy services using an electronic documentation system (i-Vent) within the EHR. During the study period, a total of 221 patients were admitted to home hospital at either site representing 3,258 inpatient medication orders with 2,997 medication administrations. Pharmacists signed 903 progress notes and documented 561 interventions across all types. The top 3 pharmacy intervention types were drug administration change (37%), medication reconciliation (29%), and antimicrobial stewardship (15%). Each of the top 3 types were further evaluated by subtype. Conclusion Documented pharmacy services encompassed a variety of intervention types. The overwhelming majority of patients admitted to the program received pharmacy consultative services, demonstrating how pivotal pharmacists are to the operational success of these programs and clinical care of HaH patients. More research is needed to expose pharmacy potential and facilitate growth for pharmacists practicing in HaH programs.
