Emergency department visits and admissions due to drug related problems at Riyadh military hospital (RMH), Saudi Arabia

Aim of this study was to prospectively determine the incidence and types of emergency department (ED) visits and admissions due to drug related problems (DRPs) at Riyadh Military Hospital (RMH), to assess the severity and preventability of these drug related admissions or visits, and to identify the drugs and patient groups that are most commonly involved. Patients (n=300) were selected randomly from patients presented to the ED during the study period (one month). Computerized randomization program was used to select ten beds daily on different areas and times. Patient was eligible to be included if either visited ED or admitted through it due to DRPs. During the study period, 300 patients presented to ED were randomly selected with a mean age of 47.8±27.7years. One hundred and forty of them were females (46.67%) and 160 were male patients (53.33%). Of these 300 patients, 56 (18.7%) were presented to ED due to DRPs, and 244 (81.3%) patients were presented to ED due to non-drug related problems (NDRPs). About ninety-three percent (n=52) of the DRP group were exposed to hospital admission while only 7.1% (n=4) were ED visits (Fig. 2). Male to female ratio in ED visits was 3:1 while it was 9.7:8.9 in the ED admission group. The prospective design of this study, sample size, and randomization increases the likelihood that our estimates are accurate and increase the generalizability of our findings. Most DRPs attributed to hospital admissions or visits were avoidable. Direct patient contact with pharmacist and family physician was beneficial in providing a safe and effective therapy. Corrective, preventive and educational strategies should concentrate on the most frequently reported populations, diseases and medications. The study addresses the proper use of medications to ensure the best outcomes of pharmacological interventions. Finally, more studies with longer duration focusing on DRPs in Saudi Arabia are needed.
