Abstract

Background: Radiation therapy consists of many steps for treating the cancer patient. The patient’s data transfer is very important. In order to prevent any errors in data transfer, such as radiation dose, number of treatment fraction, beam energy, the data checklist is necessary and will benefit in treating patients.

Objective: The purpose was to examine the data from the checklist verification document and analyze the cause of the treatment error. 

Materials and methods: Six-hundred-ninety-one patients’ checklists from Division of Radiation Oncology, King Chulalongkorn Memorial Hospital, were retrospectively reviewed from November 2018 to May 2019. The prescribed dose from the radiation oncologist and the treatment plan sheet from medical physicist were checked by radiation therapist before treatment.  The frequency and percentage of the incidence of errors were classified as man, machine, material, method, and environment. Once an error was detected, it could be immediately corrected.  The incidence was collected and analyzed to find out the causes of errors.

Results: Fitty-two events were detected from the checklist documents. These errors could be classified as a man for 30 events (57.70%), machine for 9 events (17.31%), material for 4 events (7.69%), method for 8 events (15.38%) and environmental error for 1 event (1.92%).

Conclusion: The major cause of treatment error was from human. The checklist verification document is an essential tool for treatment quality control and it is the radiation therapists responsibilities guide to do a pre-treatment verification. It helps to prevent and correct the errors before treatment delivery.
