Q Bulletin, Volume 1, No. 32 (Supplement 1), Jan - Dec 202412th National QA Convention, 8 %u2013 10 October 2024PP-31Increasing the Percentage of Patients Completed CT Scan within 90 Minutes inTaiping HospitalMohainy MW, Khaizuran KA1, Tan LS11Department of Radiology, Taiping HospitalSELECTION OF OPPORTUNITIES FOR IMPROVEMENT:Computed Tomography (CT) scan is a useful imaging technique for diagnosis of many diseases. Longwaiting time for CT scan can cause public dissatisfaction. Our pilot study in 2022 showed only 57%patients had CT examination completed within 90 minutes.KEY MEASURES FOR IMPROVEMENT:The indicator is calculated by dividing the number of patients completed CT scan within 90 minutes overtotal number of patients underwent elective CT scan. A standard of %u226570% is agreed upon duringdepartment-level discussions.PROCESS OF GATHERING INFORMATION:This QA study commenced in January 2023 and completed in December 2023. The total number ofpatients were calculated via random sampling to assess the percentage of long waiting time and to identifythe contributing factors. Implementation of remedial measures was done from April to October 2023.ANALYSIS AND INTERPRETATION:The main factor is imbalanced distribution of complex CT cases (35%). Other factors include waitingtime for image reconstruction (27%), late planning for scanning protocol (15%) and inadequate patient%u2019spreparation (15%).STRATEGY FOR CHANGE:Block system was implemented to control the number of complex scans. Radiologists started to planscanning protocol with simultaneous %u2018check and go%u2019 to eliminate waiting for image reconstruction withgood communication with the radiographers.EFFECT OF CHANGE:Percentage of patients who completed CT scans within 90 minutes had increased from 57% to 70%. Thisproject had successfully improved the service in CT scan.THE NEXT STEP:In the future, the percentage of completed CT scan within 90 days can be increased to 75%. Continuouseffort is needed to improve remedial measures and ensure sustainability.84 | Page
