Evaluation of Service-Oriented Nursing Supervisor Strategy Based on Data Envelopment Analysis (DEA)

Abstract

Background: This study introduced a service-oriented nursing supervisor strategy to increase the performance efficiency of different hospital wards. The efficiency of this strategy in 12 wards under the supervision of 12 supervisors was evaluated using Data Envelopment Analysis (DEA).

Materials and Methods: The efficiency of the service-oriented nursing supervisor strategy was evaluated using DEA. This study aims to evaluate the relative efficiency of hospital wards before and after implementing the service-oriented nursing supervisor strategy at Milad hospital. Data were evaluated using two basic models of data envelopment analysis technique, i.e., CCR and BCC output-oriented methods. Then, the relative performance efficiencies of 12 wards in 2 periods, including the first half of 2020 (before service-oriented nursing supervisor strategy) and the second half of 2020 (after service-oriented nursing supervisor strategy) were analyzed. Finally, efficient wards were ranked using the Anderson-Peterson method based on the results.

Results: According to the CCR output-oriented method, after implementing service-oriented nursing supervisor strategy, Urology, Gastroenterology, and Neurosurgery wards, as well as ENT, had the highest and lowest efficiency rates, respectively. Based on the BCC output-oriented method, Urology, Renal Transplant, Neurosurgery, and Gynecology wards had the highest efficiency in performance, while ENT had the lowest efficiency.

Conclusion: In conclusion, the findings of this study offer a service-oriented nursing supervisor strategy that improves the efficiency of different wards of the hospital.
