Economic impact of clinical pharmacist interventions in a general tertiary hospital in Qatar

Economic evaluation of clinical pharmacy service using integrated health system in tertiary care hospital

BACKGROUND

Clinical pharmacy services are the specialized practices of pharmacists to provide pharmaceutical care. All these activities are documented as pharmacist interventions to avoid medication errors which occur during prescribing, dispensing, and administration. The purpose of this study is to conduct an economic analysis of the pharmacist interventions using integrated health system.

RESEARCH DESIGN AND METHODS

A retrospective study was conducted in a tertiary care hospital. Pharmacist interventions were analyzed by an independent pharmacist. Cost-saving and cost avoidance analyses were carried out for drug-related interventions. Economic analysis was performed and tabulated both in PKR and USD.

RESULTS

Out of 1330 interventions, 1250 (95%) interventions were accepted and changed the prescription upon the physician-pharmacist consultation while 71 (5%) were not accepted. Interventions related to prescribing and duplication errors were the highest of all (30 and 29% respectively). Pharmacist interventions were recorded with a 95% acceptance rate. Cost analysis showed that pharmacist interventions saved around 105,115.88 US dollars.

CONCLUSION

Clinical pharmacy services provided by integrated health system are a cost saving program. The cost saved per intervention for our study is around USD 37 which is more than another similar study which quoted USD 30.35 per intervention.

Clinical pharmacists' interventions for preventing adverse events in critically ill neonates in Qatar: an economic impact analysis

Objective

This study aimed to assess the overall economic impact of clinical pharmacist interventions in the neonatal ICU (NICU) in Qatar.

Methods

A retrospective review of neonates' records was performed over a 3-month duration in the NICU of Qatar to determine the total economic benefit of clinical pharmacist interventions. The total benefit of interventions was calculated by considering the cost avoidance due to preventable adverse drug events (ADEs) and the cost savings associated with the revised resource use due to interventions. Sensitivity analyses were conducted to ensure the robustness and generalizability of the results.

Results

A total of 513 interventions were analyzed, involving 150 neonates. Most of the drug-related problems were related to therapy dosing, followed by drug choice appropriateness, the addition of prophylactic treatment, and administration frequency. The overall annual benefit was estimated at QAR 4,178,352 (1,147,584), which consisted of cost avoidance of QAR 1,050,680 (USD 288,648) and an overall cost saving of QAR -6091 (USD -1673).

Conclusions

While the clinical pharmacist interventions led to increased resource utilisation and associated costs, when considering the avoided costs of ADEs, the overall clinical pharmacist practices in the NICU setting were economically beneficial.
