Evaluation of Turnaround Time and the Associated Factors in CT at the Palestinian Hospitals: A Comprehensive Analysis رسالة ماجستير

Abstract

Introduction: The rising demand for computed tomography scans has put pressure on radiology departments to optimize workflows and reduce turnaround times. Turnaround times encompass the entire process from scan order to report finalization. Optimizing the turnaround time is an important factor in improving patient satisfaction and facilitating the workflow at hospitals. This study examines the average turnaround time from the computed tomography order to accept, order to result, and from accept to result at Palestinian hospitals and determines the factors influencing these times. Methods: A cross-sectional retrospective study, approved by the IRB, using data from 8,220 computed tomography scan orders from three Palestinian hospitals was carried out. Descriptive and non-parametric statistical analyses were employed to explore the association between turnaround times and variables such as order source (inpatient, outpatient, or emergency department), scan day and shift, and the utilization of contrast media. Results: The median turnaround time for order to accept, from order to result, and from acceptance to result were 78, 837, and 462 minutes, respectively. The study identified notable differences in turnaround times among the studied hospitals. The Ibn Sina Specialized had generally shorter turnaround times compared to Specialized Arab Hospital and Istishari Arab Hospital. Turnaround times vary significantly depending on working shifts, the day of the week, encounter type, and the use of contrast media. Outpatient computed tomography scans had shorter turnaround times than inpatient or emergency scans, the use of contrast media increased turnaround times, and scans performed during the weekend showed increased turnaround times. Conclusion: Computed tomography scan turnaround times are important indicators of the radiology department's productivity at the hospital. The turnaround times are significantly influenced by several factors including the order day, the working shift, the ordering source, and the use of contrast media. To enhance computed tomography scan efficiency and patient outcomes, strategies should focus on optimiz
