Pharmacist-led interventions during transitions of care of older adults admitted to short term geriatric units: Current practices and perceived barriers.

Background: During transitions of care, older adults are at risk of adverse drug events which could lead to avoidable hospital visits. Pharmacists are increasingly involved in care teams at various stages of the continuum of care. The types and frequency of clinical interventions performed by pharmacists in the geriatric practice setting remain poorly documented. Objectives: This study aimed to describe the current integration of pharmacist interventions during transitions of care of older adults admitted in short-term geriatric units (STGUs) and to explore barriers and facilitators to their implementation in clinical practice. The secondary objective was to explore associations between certain patient characteristics and pharmacist-led interventions during transitional care. Methods: A mixed methods study was conducted with pharmacists practicing in STGUs in the Montreal area, Canada. The application of 8 pharmaceutical interventions was assessed using a self-administered questionnaire, along with as a retrospective chart review. Four semi-structured group interviews were conducted in order to identify perceived barriers and facilitators. Results: Thirteen pharmacists participated in the study. In the questionnaire, medication reconciliation on admission and at discharge was reported as being performed at least half the time by 12 (92%) and 7 (54%) pharmacists, respectively. The retrospective chart review revealed that these interventions were documented in 95 (98%) and 25 (26%) files, respectively. While 35% of patients had a documented pharmaceutical care plan on admission, none was documented at discharge. Several barriers to implementing clinical interventions were identified such as lack of time, technical support, communication and standardization. Conclusions: Pharmacists are involved at different periods of transitional care; however, certain barriers should be addressed in order to expand their role in discharge planning. Providing guidelines on what is expected at discharge and post-discharge, and having a practice focused on delegation and collaboration would help pharmacists increase their role throughout the transition of care of older adults.

Impact of pharmacist interventions during transition of care in older adults to reduce the use of healthcare services: A scoping review.

BACKGROUND: Current literature has shown increasing risk of error in transition of care between different healthcare settings, especially in the older population. Moreover, drug-related hospital readmission has been reported due to lack of appropriate communication. However, the literature is not clear about the impact of pharmacist interventions during transition of care of older adults on the reduction in use of healthcare services. OBJECTIVE: The goal of the scoping review was to describe the impact of pharmacist interventions during transitions of care for older adults on the use of healthcare services. METHODS: MEDLINE was searched for randomized controlled trials and controlled studies that analyzed pharmacist interventions during transition of care of older adults with regard to use of healthcare services. Four reviewers, grouped in pairs, independently screened all references published from 1990 to 2019 and extracted and analyzed the data. A pharmaceutical model of 8 pharmacist-led interventions was adapted from literature to compare the included studies. RESULTS: There were 1527 publications screened, 17 of which met inclusion criteria. Pharmacist-led interventions decreased the use of healthcare services in 11 of these studies. The majority of studies were of very good or good quality based on Mixed Methods Appraisal Tool. Pharmacist were implicated at all times during the transition of care process (i.e. admission/during stay, discharge and post-discharge) in 4 of the effective studies, whereas none did in the not effective studies. More interventions were accomplished by pharmacists in studies with positive outcomes. CONCLUSION: By diversifying their interventions at different moments throughout transition of care, pharmacists can reduce the use of healthcare services for older adults during transition of care. This scoping review also shows the need to better understand key components of post-discharge interventions and to have a dynamic pharmaceutical model accepted by the scientific community.

Human Gut Microbiota: Toward an Ecology of Disease.

Composed of trillions of individual microbes, the human gut microbiota has adapted to the uniquely diverse environments found in the human intestine. Quickly responding to the variances in the ingested food, the microbiota interacts with the host via reciprocal biochemical signaling to coordinate the exchange of nutrients and proper immune function. Host and microbiota function as a unit which guards its balance against invasion by potential pathogens and which undergoes natural selection. Disturbance of the microbiota composition, or dysbiosis, is often associated with human disease, indicating that, while there seems to be no unique optimal composition of the gut microbiota, a balanced community is crucial for human health. Emerging knowledge of the ecology of the microbiota-host synergy will have an impact on how we implement antibiotic treatment in therapeutics and prophylaxis and how we will consider alternative strategies of global remodeling of the microbiota such as fecal transplants. Here we examine the microbiota-human host relationship from the perspective of the microbial community dynamics.
