Risk of mental illness after the diagnosis of occupational injury or disease: a retrospective cohort study.

OBJECTIVES: As studies on mental disorders in victims of occupational injury or disease are limited, this study aims to evaluate the risk of, and factors associated with, the development of mental illness in patients with occupational injury or disease using insurance claims data from Taiwan. METHODS: This retrospective cohort study analyzed insurance records in Taiwan to identify 18,285 adults who experienced occupational injury or disease in 2002-2013 and 18,285 adults without occupational injury or disease who were matched by propensity score. The risks of mental disorders during a follow-up period of up to 2 years were estimated and compared between the two cohorts. RESULTS: After controlling for other variables, the odds of mental illness in patients with occupational injury or disease was significantly higher compared to patients without occupational injury or disease. Additional factors associated with higher odds of mental disorders included female gender, age ≥ 30 years (vs. 20-29 years), Charlson comorbidity index ≥ 1, occupation category of labor union member, soldier, insured by social security, religious group member (vs. private or government employee), lower premium-based monthly salary (≤ 576 US$), treatment at a district hospital or clinic (vs. medical center), treatment at a publically-owned or consortium-owned hospital (vs. private hospital), and central or southeast geographic location (vs. Taipei). The main types of mental illness were anxiety disorder (2.79%) and other psychoses (3.29%). CONCLUSION: The risk of mental illness slightly increased during the 2-year period after the diagnosis of occupational injury or disease.

Assessment of the Risk of Oral Cancer Incidence in A High-Risk Population and Establishment of A Predictive Model for Oral Cancer Incidence Using A Population-Based Cohort in Taiwan.

We aimed to assess the risk of oral cancer incidence in a high-risk population, establish a predictive model for oral cancer among these high-risk individuals, and assess the predictive ability of the constructed model. Individuals aged ≥30 years who had a habit of smoking or betel nut chewing and had undergone oral cancer screening in 2010 or 2011 were selected as study subjects. The incidence of oral cancer among the subjects at the end of 2014 was determined. The annual oral cancer incidence among individuals with a positive screening result was 624 per 100,000 persons, which was 6.5 times that of the annual oral cancer incidence among all individuals screened. Male sex, aged 45-64 years, divorce, low educational level, presence of diabetes, presence of other cancers, high comorbidity severity, a habit of smoking or betel nut chewing, and low monthly salary were high-risk factors for oral cancer incidence (p < 0.05). The area under the curve of the predictive model for oral cancer incidence was 0.73, which indicated a good predictive ability. Therefore, the oral cancer screening policy for the high-risk population with a habit of smoking and/or betel nut chewing is beneficial for the early diagnosis of oral cancer.
