Abstract
Bakground
The quality of information from the Hospital Cancer Records (HRC) needs to be evaluated regarding coverage, completeness and agreement between the underlying cause (UC) as registered in the HRC and the Mortality Information System (SIM).
Objective
To assess the quality of the HRC in the two Instituto Mário Penna hospitals: Mário Penna (HMP) and Luxemburgo (HL) in Belo Horizonte, Minas Gerais, between 2016-2017.
Method
By capture-recapture (RHC x RHC), we assessed coverage, completeness of the “cancer death” variable and agreement between underlying cause (UC) with the cause of the research (CR), in each hospital. Deterministic relationship (RHC x SIM) was used to asses UC coverage and agreement between systems.
Results
The coverage of deaths at the HRC was good/excellent (88.8% and 95.3%); completeness was poor (34.6% and 32.6%) in HMP and HL respectively; per ICD-10 chapter, there was no agreement between CB and CP. Excellent coverage (94.7%) and agreement (94.5%) of CR and SIM were observed; 38 neoplasms were under-reported in the SIM, with reclassification of less useful causes.
Conclusion
Applying capture-recapture and deterministic linkage techniques contributed in improving the quality of information in the HRC, with a reduction in incompleteness in the HRC and correction of the UC in both HRC and SIM.
