Background: Clinical pharmacy activities in healthcare facilities are increasingly receiving attention because they contribute to safe, rational, and effective medication use and patient safety.
Objective: To describe the current status of clinical pharmacy activities, medication-order errors, pharmacist interventions, and to explore selected factors associated with medication-order errors at Tien Giang General Hospital in 2025.
Methods: A retrospective cross-sectional descriptive study was conducted using 259 inpatient medication orders from 2025. The study also summarized data from 8 clinical pharmacists and 50 treating physicians. Medication-order data were extracted and analyzed during January–March 2026. Systematic random sampling with allocation across clinical departments was applied. Descriptive statistics, 95% confidence intervals, and appropriate exploratory association tests were used.
Results: Among 259 inpatient medication orders, 6 errors or potential medication-related problems were identified, accounting for 2.32% (95% CI: 0.85–4.97). The 6 recorded cases were intervened by clinical pharmacists and accepted by physicians. Medication orders containing ≥7 drugs were associated with errors in exploratory analysis (OR = 6.23; 95% CI: 1.22–31.85; p = 0.03). Lack of clinical-pharmacy training among physicians (OR = 13.82; 95% CI: 2.48–76.92; p < 0.01) and general-practitioner level without postgraduate specialty training (OR = 3.16; 95% CI: 1.58–17.30; p = 0.04) were also associated with errors. The mean intervention time was 7.5 minutes.
Conclusion: Clinical pharmacy activities at Tien Giang General Hospital showed an initial role in detecting and intervening in inpatient medication-order errors. However, conclusions about effectiveness should be interpreted cautiously because this was a cross-sectional study and only 6 error events were identified. Priority should be given to reviewing high-drug-count medication orders, strengthening physician training in clinical pharmacy, standardizing error-classification criteria, and shortening intervention time.
