Validity of Data in Thai Cancer-based Registry Compared with Original Data from One Tertiary Care Hospital Database
Keywords:
validity, cancer database, hospital databaseAbstract
Background: Nowadays, cancer patients' data is electronically transferred to the Thai cancer base registry by the Thai Cancer Based Program, but some data were manually input causing data errors in the cancer registry database.
Objectives: This study aims to verify the basic data of cancer patients in the cancer registry database and compare them with the original data from electronic medical record database from the hospital.
Method: The research used the basic cancer data between 2015-2018 from the cancer registry database and basic data from outpatient and inpatient database from one tertiary hospital. The data were linked by using deterministic record linkage. Data were analyzed by the percentage of agreement.
Results: There are 26,138 records from both databases. Of 84 variables analyzed, we found perfect agreement on the pathological card number, recurrent, bilaterality, stage, and extend variables. The validity of personal data variables ranges from 63.29 to 99.99 percent, the tumor-related variables 51.19 to 100 percent, treatment-related variables 63.29 to 96.60 percent, and follow-up data-related variables 17.99 to 96.86 percent.
Conclusion: Basic data of patients from the cancer registry database show various validities. Variables with low agreement should be corrected. In addition, validation process must be implemented.
