Pattern of utilization, disease presentation, and medication prescribing and dispensing at 51 primary healthcare centers during the Hajj mass gathering.

BACKGROUND: The majority of pilgrims seeking healthcare during Hajj are seen at primary healthcare centers (PHCCs). Data on the utilization of these facilities during Hajj can aid in directing optimal health services delivery and allocation of resources during the pilgrimage. METHOD: We investigated the pattern of disease presentation, caseload, and medication prescribing and dispensing at 51 PHCCs during the 2019 Hajj. Data on patients' demographics, diagnoses, and prescribed medications were retrieved from each PHCC's electronic records and analyzed. Data were also used to calculate six of the World Health Organization (WHO) indicators for drug use at these facilities. RESULTS: Data were captured for 99,367 patients who were mostly Hajj pilgrims (95.4%), male (69.1%) from the Eastern Mediterranean (60.8%) and had a mean age of 46.6 years (SD = 14.9). Most patients (85.2%) were seen in Mina and towards the end of Hajj. The majority of patients (96.0%) had a single diagnosis; most commonly, respiratory (45.0%), musculoskeletal (17.2%), and skin (10.5%) diseases. Patients were prescribed 223,964 medications, mostly analgesics (25.1%), antibacterials for systemic use (16.5%), anti-inflammatory and antirheumatic products (16.4%), and cough and cold preparations (11.9%). On average, 2.25 (SD = 0.94) medications were prescribed per consultation, with low (1.3%) prevalence of polypharmacy. An antibiotic and an injectable were prescribed in 43.6 and 2.67% of patient encounters, respectively. Most (92.7%) of the prescribed drugs were actually dispensed, in an average time of 8.06 min (SD = 41.4). All PHCCs had a copy of the essential drugs list available, on which all the prescribed drugs appeared. CONCLUSION: Respiratory illnesses are the main reason for PHCCs visits during Hajj, and analgesics and antibiotics are the most common medications prescribed to pilgrims. Our results, including the calculated WHO drug use indicators, contribute to evidence-based optimization of primary healthcare services during Hajj.
