Occupational health patients' parallel use of primary- and secondary-care services and linkage to work disability: A follow-up study in Finland.

AIMS: This study aimed to investigate occupational health (OH) primary-care patients' use of other health-care services and whether parallel use affects their likelihood to have sickness absences (SA) or disability pensions (DP). METHODS: Primary-care services in Finland are provided through three parallel health-care sectors, all available to the working population: public, private and OH sectors. Patients may also be referred to secondary care. This follow-up study combines real-world medical record data containing SA data from a nationwide OH provider with health-care attendance data from public and private primary-care sectors and public secondary care, sociodemographic data and DP decisions. Patients between 18 and 68 years of age who used OH primary care at least once during the study years 2014-2016 were included. The total study population comprised 59,650 patients. Odds ratios were used to analyse association between parallel service use and SA or DP. RESULTS: Females and patients with a lower educational level were more likely to use services in other health-care sectors in addition to OH than others. Those patients who used any other health-care sector in addition to OH primary care had an increased likelihood of having long SA or receiving DP. CONCLUSIONS: OH primary-care patients using the services of several health-care sectors in parallel have an increased likelihood of receiving disability benefits - either SA or DP. There is need for care coordination to ensure adequate measures for work-ability support.

Parallel use of primary and secondary healthcare by frequent attenders in occupational health and their work disability: a longitudinal study in Finland.

OBJECTIVES: To investigate occupational health frequent attenders' (FAs) use of other healthcare sector services and whether parallel use affects their likelihood to receive a disability pension. DESIGN: Longitudinal study combining routine medical record data with register data. SETTING: Primary care in Finland is provided through three parallel healthcare sectors, all available to the working population. Additionally, patients can be referred to secondary care. This study combines medical record data from a nationwide occupational healthcare provider, with healthcare attendance data from private care and from public primary and secondary care attendance, sociodemographic data and disability pension decisions. PARTICIPANTS: Patients between 18 and 68 years of age who used occupational health primary care at least once during the study years 2014-2016 were included. The total study population was 59 650 patients. They were divided into three groups (occasional and persistent FAs and non-FAs) for analysis. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was FAs parallel use of private care and public primary and secondary care. The secondary outcome was work disability pension granted to FAs who used several healthcare sectors. RESULTS: Both FA groups were more likely to use other healthcare service sectors more than non-FAs did. Persistent FAs were likely to use public secondary care services in particular (OR 4.31 95% CI 3.46 to 5.36). FAs using all healthcare sectors were also more likely to receive a disability pension than those FAs using only occupational health services (OR 4.53 (95% CI 1.54 to 13.34). This association was strengthened by attendance in public secondary care. CONCLUSIONS: FAs using several healthcare sectors in parallel have an increased likelihood to receive a disability pension. There is need for care coordination to ensure adequate measures for work ability support.

Sociodemographic characteristics and disability pensions of frequent attenders in occupational health primary care - a follow-up study in Finland.

BACKGROUND: Work disability is a complex issue that requires preventive efforts from healthcare systems and individuals, and that too often results in disability pensions (DP). While many studies have attempted to characterize risk factors of work disability, many showing for example a link between socioeconomic positions, working conditions and frequent attendance to OH primary care it is not known if frequent attendance is associated with DP despite the sociodemographic factors. This study aims to address this gap and examine the association between frequent attendance to OH primary care and DP, when adjusted by sociodemographic factors. METHODS: This study combines routine medical record data of an occupational health service provider with comprehensive national registers. Medical record data were used to define groups of frequent attenders to OH primary care (FA) (1-year-FA, 2-year-FA, persistent-FA and non-FA) from 2014 to 2016. The sociodemographic factors (including i.e. educational level, occupational class, unemployment periods) were derived from Statistic Finland and DP decisions were derived from Finnish Centre for Pensions. Association of frequent attendance to OH primary care with DP decisions were analyzed and adjusted by sociodemographic factors. RESULTS: In total, 66,381 patients were included. Basic and intermediate education along with manual and lower non-manual work predicted frequent attendance to OH primary care. Unemployment in 2013 did not predict frequent attendance to OH primary care. Frequent attendance to OH primary care was associated with DP within next two years, even when adjusted for sociodemographic factors. The association of frequent attendance to OH primary care with DP grew stronger as high service use persisted over time. CONCLUSIONS: Frequent attendance to OH primary care is associated with DP risk in the near future despite the underlying sociodemographic differences. Patients using OH primary care services extensively should be identified and rehabilitative needs and measures necessary to continue in the work force should be explored. Sociodemographic issues that co-exist should be explored and considered when planning interventions.

Subjective cognitive complaints and permanent work disability: a prospective cohort study.

PURPOSE: Work disability (WD) is a medico-legal concept that refers to disability benefits (DB) granted due to diseases. We assessed whether subjective cognitive complaints (SCC)-presenting as self-rated difficulties of concentration, memory, clear thinking, and decision making-predict permanent WD in knowledge-intensive occupations. METHODS: In this prospective cohort study with up to 7-year follow-up, we combined the SCC questionnaire results with reliable registry data on the DBs of 7161 professional/managerial employees (46% females). We excluded employees who were on long-term sickness absence (SA) or had received a DB at baseline. The exposure variable was the presence of SCC. Age and SA before the questionnaire as a proxy measure of general health were treated as confounders and the analyses were conducted by gender. The outcome variable was a granted DB. The cumulative incidence function illustrates the difference between SCC categories, and the Fine-Gray model estimates the predictors of WD during the 8-year follow-up. RESULTS: The annual incidence of DB was 0.15% in the entire cohort: 0.18% among the females, and 0.12% among the males (p = 0.795). The most common primary reasons for permanent WD were mental (36%) and musculoskeletal (20%) disorders. SCC predicted DB in both genders when controlling for age and prior SA. Hazard ratios were 2.9 with a 95% confidence interval 1.4-6.0 for the females and 3.7 (1.8-7.9) for the males. CONCLUSION: Subjective cognitive complaints predict permanent WD in knowledge-intensive occupations. This finding has implications for supporting work ability and preventing work disability among employees with cognitively demanding tasks.

Subjective cognitive complaints and sickness absence: A prospective cohort study of 7059 employees in primarily knowledge-intensive occupations.

Knowledge-intensive work requires capabilities like monitoring multiple sources of information, prioritizing between competing tasks, switching between tasks, and resisting distraction from the primary task(s). We assessed whether subjective cognitive complaints (SCC), presenting as self-rated problems with difficulties of concentration, memory, clear thinking and decision making predict sickness absence (SA) in knowledge-intensive occupations. We combined SCC questionnaire results with reliable registry data on SA of 7743 professional/managerial employees (47% female). We excluded employees who were not active in working life, on long-term SA, and those on a work disability benefit at baseline. The exposure variable was the presence of SCC. Age and SA before the questionnaire as a proxy measure of general health were treated as confounders and the analyses were conducted by gender. The outcome measure was the accumulated SA days during a 12-month follow-up. We used a hurdle model to analyse the SA data. SCC predicted the number of SA days during the 12-month follow-up. The ratio of the means of SA days was higher than 2.8 as compared to the reference group, irrespective of gender, with the lowest limit of 95% confidence interval 2.2. In the Hurdle model, SCC, SA days prior to the questionnaire, and age were additive predictors of the likelihood of SA and accumulated SA days, if any. Subjective cognitive complaints predict sickness absence in knowledge-intensive occupations, irrespective of gender, age, or general health. This finding has implications for supporting work ability (productivity) among employees with cognitively demanding tasks.

Self-reported health problems in a health risk appraisal predict permanent work disability: a prospective cohort study of 22,023 employees from different sectors in Finland with up to 6-year follow-up.

PURPOSE: Work disability (WD) as a medico-legal concept refers to disability benefits (DB) that are granted due to diseases that permanently reduce work ability. We studied whether an occupational healthcare instrument for the prediction of sickness absence (SA) risk-a health risk appraisal (HRA)-also predicts permanent WD. METHODS: HRA results were combined with registry data on DB of 22,023 employees from different industry sectors. We analysed how the HRA risk categories predict DB and considered occupational group, gender, age, and prior SA as confounding variables. Cumulative incidence function illustrates the difference between the HRA risk categories, and the Fine-Gray model estimates the predictors of WD during 6-year follow-up. RESULTS: The most common primary reasons for permanent WD were musculoskeletal (39%) and mental disorders (21%). Self-reported health problems in the HRA, labelled as "WD risk factors", predicted DB when controlling for age and prior SA. Hazard ratios were 10.9 or over with the lower limit of the 95% confidence interval 3.3 or over among those with two simultaneous WD risk factors. 14% of the females and 17% of the males with three or more simultaneous WD risk factors had received a DB, whereas the respective figures among those without findings were 1.9% and 0.3%. CONCLUSIONS: Self-reported health problems in the HRA, especially multiple simultaneous WD risk factors, predict permanent WD among both genders across occupational groups. Screening WD risk with a self-administered questionnaire is a potential means for identifying high-risk employees for targeting occupational healthcare actions.

Self-reported health problems and obesity predict sickness absence during a 12-month follow-up: a prospective cohort study in 21 608 employees from different industries.

OBJECTIVES: To study whether self-reported health problems predict sickness absence (SA) from work in employees from different industries. METHODS: The results of a health risk appraisal (HRA) were combined with archival data of SA of 21 608 employees (59% female, 56% clerical). Exposure variables were self-reported health problems, labelled as 'work disability (WD) risk factors' in the HRA, presence of problems with occupational well-being and obesity. Age, socioeconomic grading and the number of SA days 12 months before the survey were treated as confounders. The outcome measure was accumulated SA days during 12-month follow-up. Data were analysed separately for males and females. A Hurdle model with negative binomial response was used to analyse zero-inflated count data of SA. RESULTS: The HRA results predicted the number of accumulated SA days during the 12-month follow-up, regardless of occupational group and gender. The ratio of means of SA days varied between 2.7 and 4.0 among those with 'WD risk factors' and the reference category with no findings, depending on gender and occupational group. The lower limit of the 95% CI was at the lowest 2.0. In the Hurdle model, 'WD risk factors', SA days prior to the HRA and obesity were additive predictors for SA and/or the accumulated SA days in all occupational groups. CONCLUSION: Self-reported health problems and obesity predict a higher total count of SA days in an additive fashion. These findings have implications for both management and the healthcare system in the prevention of WD.

Effect of comorbidity on the risk of death associated with antipsychotic use among community-dwelling older adults.

BACKGROUND: Antipsychotics are associated with adverse events and mortality among older adults with dementia. The objective of this study was to evaluate the risk of death associated with antipsychotic use among community-dwelling older adults with a range of comorbidities. METHODS: This was a population-based cohort study of all 2,224 residents of Leppävirta, Finland, aged ≥65 years on 1 January 2000. Records of all reimbursed drug purchases were extracted from the Finnish National Prescription Register and diagnostic data were obtained from the Special Reimbursement Register. All-cause mortality was evaluated over a nine-year follow-up period. Time-dependent Cox proportional hazard models were used to compute unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of mortality of antipsychotic use compared to non-use. RESULTS: In total, 332 residents used antipsychotics between 2000 and 2008. The unadjusted HR for risk of death associated with antipsychotic use was 2.71 (95% CI = 2.3-3.2). After adjusting for baseline age, sex, antidepressant use, and diagnostic confounders, the HR was 2.07 (95% CI = 1.73-2.47). The adjusted HR was the highest among antipsychotic users with baseline respiratory disease (HR = 2.21, 95% CI = 1.30-3.76). CONCLUSIONS: The increased risk of death associated with antipsychotic use was similar across diagnostic categories, the highest being among those with baseline respiratory disease. However, the results should be interpreted with caution, as the overall sample size of antipsychotic users was small. As in other observational studies, residual confounding may account for the higher mortality observed among antipsychotic users. Further research is needed to confirm these findings.

Mortality associated with benzodiazepines and benzodiazepine-related drugs among community-dwelling older people in Finland: a population-based retrospective cohort study.

OBJECTIVE: To investigate the association between the use of benzodiazepines (BDZs) and BDZ-related drugs and mortality among community-dwelling people aged 65 years and older in Finland. METHOD: This was a population-based retrospective cohort study. Records of all reimbursed drugs purchased by all 2224 residents of Leppävirta, Finland, aged 65 years and older in 2000 were extracted from the Finnish National Prescription Register. Diagnostic data were extracted from the Special Reimbursement Register. All-cause mortality was assessed after 9 years using national registers. Cox proportional hazards models were used to compute unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals for mortality among prevalent users of BDZs and BDZ-related drugs in 2000 (n = 325), compared with nonusers of BDZs and BDZ-related drugs between 2000 and 2008 (n = 1520). RESULTS: BDZs and BDZ-related drugs were used by 325 out of the 2224 residents (14.6%) in 2000. The 9-year mortality was 50.2% among BDZ and BDZ-related drug users in 2000 and 36.3% among BDZ and BDZ-related drug nonusers between 2000 and 2008 (HR 1.53; 95% CI 1.28 to 1.82). After adjusting for baseline age, sex, antipsychotic drug use, and diagnostic confounders, the HR was 1.01 (95% CI 0.84 to 1.21). CONCLUSIONS: Use of BDZs and BDZ-related drugs was associated with an increased mortality hazard in unadjusted analyses. However, after adjusting for age, sex, antipsychotic drug use, and diagnostic confounders, the use of BDZs and BDZ-related drugs was not associated with excess mortality.
