Clinical and economic outcomes of hospital pharmaceutical care: a systematic review and meta-analysis

Background Hospital clinical pharmacists have been working in many countries for many years and clinical pharmaceutical care have a positive effect on the recovery of patients. In order to evaluate the clinical effectiveness and economic outcomes of clinical pharmaceutical care, relevant clinical trial studies were reviewed and analysed. Methods Two researchers searched literatures published from January 1992 to October 2019, and screened them by keywords like pharmaceutical care, pharmaceutical services, pharmacist interventions, outcomes, effects, impact, etc. Then, duplicate literatures were removed and the titles, abstracts and texts were read to screen literatures according to inclusion and exclusion criteria. Key data in the literature were extracted, and Meta-analysis was conducted using the literature with common outcome indicators. Results A total of 3299 articles were retrieved, and 42 studies were finally included. Twelve of them were used for meta-analysis. Among the 42 studies included, the main results of pharmaceutical care showed positive effects, 36 experimental groups were significantly better than the control group, and the remaining 6 studies showed mixed or no effects. Meta-analysis showed that clinical pharmacists had significant effects on reducing systolic blood pressure and diastolic blood pressure and shortening hospitalization days ( P < 0.05), but no statistical significance in reducing medical costs ( P > 0.05). Conclusion Clinical pharmacists’ pharmaceutical care has a significant positive effect on patients’ clinical effects, but has no significant economic effect.
