Assessment of a Geriatric Evaluation and Management in the Home (GEMITH) Service at a Quaternary Hospital: A Retrospective Observational Study.

Background: The increasing aging population in Australia has created a higher demand for specialist geriatric services within hospitals. A Geriatric Evaluation and Management in the Home (GEMITH) service was implemented at a quaternary Queensland hospital. The GEMITH service was unique as it incorporated a specialist pharmacist into the multidisciplinary team. Objective: To determine the medication safety and quality impact of the GEMITH service by evaluating the type and clinical significance of specialist pharmacist interventions. Methods: This was retrospective observational study of clinical interventions made by the GEMITH pharmacist for patients admitted to the service between October 2020 to April 2021. All pharmacist interventions were rated for their clinical significance using the Society of Hospital Pharmacists of Australia (SHPA) risk classification system. The ratings were undertaken by a panel of three pharmacists that independently assessed the interventions, coming together for final discussion. A narrative analysis of the interventions were derived through group consensus. Results: There was a total of 119 admissions to the GEMITH service, with 132 clinical interventions made by the specialist geriatric pharmacist. The majority (47%) of interventions were considered as low risk interventions, although high- (21%) and extreme-risk (2%) interventions still occurred. The most common type of intervention (32%) involved medication reconciliation. Other intervention types included monitoring recommendations, dosing interventions, and deprescribing suggestions. Conclusion: Multiple clinical interventions were made by the GEMITH pharmacist, which prevented possible and significant medication-related harm. This demonstrated the quality impact of the specialist pharmacist in improving medication safety for geriatric patients.
