Health and Mortality in Korean Healthcare Workers

Abstract

Background To evaluate the health status of healthcare workers (doctors and nurses) compared to those in the general population based on the National Health Insurance Service database and the cause of death data from Statistics Korea. Methods The subjects of this study were 104,484 doctors and 220,310 nurses working in healthcare facilities from 2002 to 2017, and who had undergone at least one general medical examination. Based on the subject definition, the subject data were extracted from the National Health Insurance healthcare facility database and qualification database. We collected medical use details included in the research database, general medical examination results, medical history included in the health examination database, and additional data on the cause of death from the National Statistics database to analyze the main cause of death and mortality. Results In terms of the major causes of death and mortality among healthcare workers, the mortality rate associated with intentional self-harm, injury, transportation accident, heart disease, addiction, and falling was significantly higher than that in the general population. Further, the prevalence of respiratory and gastrointestinal diseases was high. When analyzing the proportional mortality ratio (PMR) by cause of death for healthcare workers, the PMR values for death related to malignant neoplasm was the highest. In terms of diseases, both doctors and nurses had higher rates of infectious diseases such as maternal sepsis, rubella, and measles. Conclusion The health status of healthcare workers differs from that of the general population. Thus, it is important to consider the occupational characteristics of healthcare personnel. This study is unique in that it was conducted based on medical use indicators rather than survey data.

Cancer Incidence in Korean Healthcare Workers in Hospitals

“…Excess SIRs in the breast, mesothelial and soft tissue, and female genital organs were observed only in female HHCWs. This is consistent with the findings of a previous study that the highest causes of cancer-related mortality were bronchial and lung cancer in male HHCWs and breast cancer in female HHCWs [ 8 ]. One possible explanation for this phenomenon is the different job distributions between the sexes.…”

“…Previous studies reported high cancer incidence among HCWs [ 5 , 6 , 7 ]; however, the results were inconsistent. Furthermore, a standardized cancer incidence among HHCWs in South Korea has not been reported, although cancer in HCWs has been consistently focused on and issued in the occupational safety and health area [ 8 , 9 , 10 ]. This study aimed to investigate the high incidence of cancer among HHCWs compared with total workers and public officials.…”

“…Beneficiaries who did not fit into the employee type category were referred to as local-type beneficiaries. Employment status was defined by the Occupational Regulations (INDTP_CD) codes in the qualification database of the NHIS [ 9 ]. If any occupational information was identified, the subject was classified as a “worker” and if not, a “non-worker”.…”

“…Thus, analyzing the mortality rates due to the causes of death of healthcare practitioners, their values asso-ciated with malignant neoplasms were high enough. The prevalence of respiratory and gastrointestinal systems diseases was also higher than in general population (Shin et al 2022). Interviewing doctors in Finland revealed that, on average, they consider their working condi-tions to be good and better than those in representatives of other professional groups.…”
