Abstract Purpose Home hospital programs are rapidly becoming a more common patient care model in the market. The impact on hospital pharmacy practices is not well defined. This article describes the development of pharmacy services in a home hospital program in an attempt to help other organizations create their own home hospital pharmacy programs. Summary Caring for acutely ill patients in their home was a novel idea when Mayo Clinic began considering this in January 2020. Since then, the coronavirus disease 2019 (COVID-19) pandemic has rapidly escalated interest in and pursuit of these programs. One question we asked ourselves, and many colleagues are asking us today, is “How does pharmacy fit in?” Through 2 years of active engagement, innovation, and persistence, our team has developed a robust pharmacy presence in the home hospital care team and a well-articulated approach to medication management for our patients. We have tightly aligned and blended our clinical efforts to mirror our typical inpatient and ambulatory care clinical activities. We have also developed and modified our dispensing functions to serve the unique needs of the care model. Conclusion Home hospital medication management is both complex and ripe with opportunities for pharmacy engagement.

BCG vaccine has been used for 100 years to prevent tuberculosis. Not all countries, including the United States, adopted the initial World Health Organization recommendation to use BCG. Moreover, many Western countries that had routinely used BCG have discontinued its use. Recent population studies demonstrate lower prevalence of Alzheimer’s disease (AD) in countries with high BCG coverage. Intravesicular instillation of BCG is also used to treat bladder cancer that has not invaded the bladder muscle wall and has been shown to reduce recurrence. Several retrospective studies of bladder cancer patients demonstrated that BCG treatment was associated with a significantly reduced risk of developing AD. Plasma amyloid β assessment has become a fertile area of study for an AD biomarker that is predictive of a positive amyloid PET scan. Mass spectrometry-based plasma amyloid 42/40 ratio has proven to be accurate and robust, and when combined with age and ApoE, is shown to accurately predict current and future brain amyloid status. These parameters, amyloid 42/40 ratio, age and ApoE genotype are incorporated into an Amyloid Probability Score (APS)–a score that identifies low, intermediate or high risk of having a PET scan positive for cerebral amyloid. Community recruitment was used for this open-label pilot study. Forty-nine BCG-naïve, immunocompetent individuals completed our study: prior to BCG prime and boost, as determined by the APS, 34 had low risk (APS 0–35), 5 had intermediate risk (APS 36–57) and 10 had high risk (APS 58–100). The APS range for the participant group was 0 to 94. Follow-up plasma amyloid testing 9 months after vaccination revealed a reduction in the APS in all the risk groups: low risk group (p = 0. 37), intermediate risk group (p = 0.13) and the high-risk group (statistically significant, p = 0.016). Greater benefit was seen in younger participants and those with the highest risk. The small number of participants and the nascent status of plasma amyloid testing will rightfully temper embracement of these results. However, both the favorable direction of change after BCG as well as the utility of the APS—a valuable surrogate AD biomarker—may prompt a definitive large-scale multicenter investigation of BCG and AD risk as determined by plasma amyloid peptide ratios and APS.
