Evaluating the Impact of a Collaborative Medication Therapy Management (MTM) Program Led by Pharmacy and Nursing Technicians on Preventing Adverse Drug Events and Improving Medication Safety in Elderly Patients in KSA: A Cross-Sectional Study

Abstract

Medication safety is a critical concern for elderly patients who often take multiple medications for various chronic
conditions. Adverse drug events (ADEs) are a significant cause of morbidity and mortality in this population. This
cross-sectional study aimed to evaluate the impact of a collaborative medication therapy management (MTM)
program led by pharmacy and nursing technicians on preventing ADEs and improving medication safety in elderly
patients in KSA. A sample of 500 elderly patients (aged ≥65 years) was recruited from various healthcare settings in
KSA. Data were collected using a structured questionnaire and medical record review. The main outcome measures
were the incidence of ADEs, medication adherence, and patient satisfaction with the MTM program. Descriptive
and inferential statistics were used to analyze the data. The results showed that the MTM program significantly
reduced the incidence of ADEs (from 25% to 10%, p<0.001), improved medication adherence (from 60% to 85%,
p<0.001), and enhanced patient satisfaction (from 70% to 95%, p<0.001) compared to the standard care group. The
findings suggest that a collaborative MTM program led by pharmacy and nursing technicians can effectively prevent
ADEs and improve medication safety in elderly patients. Healthcare providers should consider implementing such
programs to optimize medication use and improve patient outcomes in this vulnerable population.
