Sickness presenteeism today, sickness absenteeism tomorrow? : A prospective study on sickness presenteeism and future sickness absenteeism

Objective: To prospectively investigate whether sickness presenteeism (SP), ie, going to work despite illness, has an impact on future sickness absenteeism. Methods: Two study populations were used, one female dominated from the public sector that included 3757 employees, and one male dominated from the private sector comprising 2485 employees. Results: SP on more than five occasions during the baseline year (2000) was a statistically significant risk factor for future sick leave (2002 and 2003) of more than 30 days among both populations even after adjusting for previous sick leave, health status, demographics, lifestyle, and work-related variables (2002, public sector, relative risk = 1.40; private sector, relative risk = 1.51). Conclusions: SP may be an important phenomenon to consider when evaluating measures aimed at decreasing sickness absenteeism because more SP may lead to future sickness absence.

Workplace expansion, long-term sickness absence, and hospital admission

BACKGROUND Downsizing has in previous studies, as well as in public debate, been associated with increased sickness absence. No studies have, however, looked at the long-term relation between workplace expansion and morbidity. METHODS We investigated exposure to personnel change during 1991-96 in relation to long-term (90 days or longer) medically certified sickness absence and hospital admission for specified diagnoses during 1997-99 in 24?036 participants with a complete employment record in the biennial national Swedish Work Environment Surveys from 1989 to the end of 1999. FINDINGS Accumulated exposure to large expansion (> or =18% per year) was related to an increased risk of long-term sickness absence (odds ratio 1.07 [95% CI 1.01-1.13], p=0.013) and hospital admission (1.09 [1.02-1.16], p=0.017). In this context, odds ratio signifies the change in odds for each additional year of exposure, varying from 0 to 6. Moderate expansion (> or =8% and <18% per year), was associated with a decreased risk of admission (0.91 [0.84-0.98], p=0.012). Moderate downsizing (> or =8% and <18% per year) was associated with an increased risk of sickness absence (1.07 [1.02-1.12], p=0.003). The strongest association between large expansion and sickness absence was in women in the public sector (1.18 [1.08-1.30], p=0.0002), corresponding to an odds ratio of 2.77 [1.62-4.74] between full exposure (all 6 years) and no exposure. INTERPRETATION This study confirms earlier findings that downsizing is associated with health risks. It also shows that repeated exposure to rapid personnel expansion, possibly connected with centralisation of functions, statistically predicts long-term sickness absence and hospital admission. Although no conclusions about causal pathways can be drawn from our results, this exposure should be considered in future studies, policy making, and occupational health care practice.

Frequency and nature of problems associated with sickness certification tasks: A cross-sectional questionnaire study of 5455 physicians

Objective. To study the frequency and nature of problems associated with physicians’ sickness certification practices. Design. Cross-sectional questionnaire study. Setting. Stockholm and Östergötland Counties in Sweden. Subjects. Physicians aged ≤64 years, n =7665, response rate 71% (n =5455). Main outcome measures. The frequency of consultations involving sickness certification, the frequency and nature of problems related to sickness certification. Results. A total of 74% (n =4019) of the respondents had consultations including sickness certification at least a few times a year. About half of these physicians had sickness certification cases at least six times a week, and 1 out of 10 (9.4%) had this more than 20 times a week. The items that the highest percentage of physicians rated as very or fairly problematic included: handling conflicts with patients over certification, assessing work ability, estimating optimal length and degree of absence, and managing prolongation of sick leave initially certified by another physician. There were large differences in frequency and nature of problems between different types of clinics/practices. General practitioners had the highest frequency of problems concerning sickness certification while the lowest was found among specialists in internal medicine and surgery. Conclusion. Sickness certification should be recognized as an important task also for physicians other than general practitioners. The physicians experienced problems with numerous tasks related to sickness certification and these varied considerably between types of clinics. The high rate of problems experienced may have consequences for the physicians’ work situation, for patients, and for society.

Diagnosis-specific sick leave as a risk marker for disability pension in a Swedish population

Objective: To investigate diagnosis-specific sick leave as a risk marker for subsequent disability pension. Design: A prospective population based cohort study. Exposure to a new medically certified sick leave episode of more than seven days by diagnosis during 1985 was examined in relation to incident cause-specific disability pension through 1996. Participants: The total non-retired population of one Swedish county aged 16 to 49 years, alive and not in receipt of a disability pension at the end of 1985 (176 629 persons; 51% men). Main results: To eliminate confounding by sick leaves that translate into a disability pension, the follow up period for disability pension was started five years after the assessment of sick leave. After adjustment for demographic characteristics, the risk of disability pension from mental disorders was 14.1 times higher (95% confidence interval (CI), 12.1 to 16.4) for those with sick leave for mental disorders than for those with no sick leave. The corresponding hazard ratio for sick leave and disability pension within diagnostic category was 5.7 (95% CI, 5.3 to 6.2) for musculoskeletal diseases and 13.0 (7.7 to 21.8) for gastrointestinal diseases. Irrespective of diagnoses, the hazard ratio for sick leave and disability pension was 3.0 (2.9 to 3.1). Conclusions: Sick leave may provide an important risk marker for identifying groups at high risk of a disability pension, especially for psychiatric diagnoses.

Cost effectiveness of two rehabilitation programmes for neck and back pain patients: A seven year follow-up

ABSTRACT The cost effectiveness of work‐oriented rehabilitation for persons on long‐term sick leave needs to be assessed. This prospective observational study presents a follow‐up seven years after rehabilitation using two different evidence‐based work‐oriented regimens. Individuals on sick leave for neck and back pain were referred to two rehabilitation programmes in Sweden. The first programme was a relatively low‐intensity programme based on orthopaedic manual therapy and exercise programme (OMTP). The second programme was a full‐time multidisciplinary programme (MDP). The primary outcome was sickness absence seven years after intervention. Cost effectiveness was calculated on the basis of loss of production due to sickness absence. The results show that participants referred to MDP and with less than 60 sick days before rehabilitation have reduced sickness absence after intervention as compared to matched controls. This corresponds to a cost reduction of about 94,494 EUR per referred individual. Further, the results indicate that participants of the OMTP who have more than 60 sick days before rehabilitation have a statistically significant increased risk of disability pension. This means increased cost in terms of loss of production of 44,593 EUR per referred individual. The results of this study show that MPD but not OMTP achieves the goal of working life‐oriented rehabilitation. A direct comparison between the rehabilitation programmes strengthened the assumption that long‐term sickness absence prior to rehabilitation is associated with more days on sick leave after rehabilitation. This analysis also indicated the importance of participants’ pain self‐efficacy beliefs and recovery beliefs on rehabilitation outcome.

Dealing with sickness certification – a survey of problems and strategies among general practitioners and orthopaedic surgeons

BackgroundIn order to get sickness benefit a sick-listed person need a medical certificate issued by a physician; in Sweden after one week of self-certification. Physicians experience sick-listing tasks as problematic and conflicts may arise when patients regard themselves unable to work due to complaints that are hard to objectively verify for the physician. Most GPs and orthopaedic surgeons (OS) deal regularly with sick-listing issues in their daily practice. The aim of this study was to explore perceived problems and coping strategies related to tasks of sickness certification among general practitioners (GP) and orthopaedic surgeons (OS).MethodsA cross-sectional study about sickness certification in two Swedish counties, with 673 participating GPs and 149 OSs, who answered a comprehensive questionnaire. Frequencies together with crude and adjusted (gender and working years) Odds ratios were calculated.ResultsA majority of the GPs and OSs experienced problems in sickness certification every week. To assess the patients work ability, to handle situations when they and the patient had different opinions about the need for sickness absence, and to issue prolongation certificates when the previous was issued by another physician were reported as problematic by a majority in both groups. Both GPs and OSs prolonged sickness certifications due to waiting times in health care or at Social Insurance Office (SIO). To handle experienced problems they used different strategies; OSs issued sickness certificates without personal appointment more often than the GPs, who on the other hand reported having contact with SIO more often than the OSs. A higher rate of GPs experienced support from management and had a common strategy for handling sickness certification at the clinic than the OSs.ConclusionMost GPs and OSs handled sickness certification weekly and reported a variety of problems in relation to this task, generally GPs to a higher extent, and they used different coping strategies to handle the problems.

Does a Change in Psychosocial Work Factors Lead to a Change in Employee Health

Objective: The aim was to identify psychosocial factors at work that promote positive changes in employee health and factors that prevent negative changes in employee health. Method: This study is part of a large longitudinal study and includes 1212 employees. Data for psychosocial work factors and self rated health was collected in 2000 and 2003. A modified Poisson regression was used to find factors of relevance for positive and negative changes in health. Results: A negative change in leadership, organizational commitment and reporting job strain increased the risk for negative change in health. Improved leadership and social climate increased the chance for positive changes in health. Conclusion: By improving psychosocial factors at work, it is possible to promote employee health as well as prevent employee ill-health.

Sickness absence with musculoskeletal or mental diagnoses, transition into disability pension and all-cause mortality: A 9-year prospective cohort study

Aims: Increased early mortality indicates poor health. This study assessed mortality among men and women after long-term sickness absence (LTSA) with musculoskeletal or mental diagnoses. A special focus was on possible differences in mortality among women and men who obtained disability pension (DP) as compared to those who did not. Methods: This was a 9-year prospective cohort study in Hordaland County, Norway, including 1417 women and 1075 men aged 16—62 years with a spell of LTSA 48 weeks, and with a musculoskeletal or mental diagnosis. The endpoint was death from all causes. Age-standardised mortality rates for those who obtained DP and those who did not were calculated and compared. Cox proportional hazards analysis was used to assess DP status and other possible predictors of premature death. All analyses were stratified for gender. Results: Overall, 36% obtained a DP and 3.2% died. Among the men, 7.2% with mental diagnoses and 4.4% with musculoskeletal sick-leave diagnoses died. Among the women, 1.9% died in both groups. Among the men, 5.6% of the DP recipients died, as compared to 4.6% among those without DP. The respective figures for the women were 2.9% and 1.3%. Male gender, increasing age and low income among men increased the mortality risk significantly. After adjustments for these variables, the hazard ratios associated with DP were 2.9 (95% confidence interval (CI) 1.2—7.0) for women and 2.3 (95% CI 1.2—4.5) for men. Conclusions: When monitoring those on LTSA, one should be aware of the high mortality among those who obtain DP and male workers with low income, and preventive actions should be considered.

A multi-component universal intervention to improve diet and physical activity among adults with intellectual disabilities in community residences: A cluster randomised controlled trial §

People with ID have an increased risk for unhealthy diets, physical inactivity and weight disturbances. The aim of the current study was to investigate the effectiveness of a novel and complex intervention to improve diet and physical activity, targeting both caregivers and residents, in community residences for people with ID. A three component intervention based on Social Cognitive Theory was developed, including: (1) appointment of a health ambassador in each community residence attending network meetings, (2) a study circle for caregivers, and (3) a health course for the residents. The intervention lasted for 12-16 months and allowed for some local tailoring. A cluster randomised controlled trial, randomised at residence level, was conducted to evaluate the effects of the intervention. Thirty community residences for people with mild or moderate ID in Stockholm County, Sweden, were included. A total of 130 participants, 74 women and 56 men aged 20-66 years, entered, and 129 participants completed the study. The primary outcome was physical activity, measured by pedometry. Secondary outcomes were BMI, waist circumference, dietary quality measured by digital photography, satisfaction with life assessed with a scale, and work routines assessed with a questionnaire. Outcomes were related to intervention fidelity. A positive intervention effect was found on physical activity, with an average increase of 1608 steps/day among participants in the intervention group (P=0.045). The effect size was 0.29 (Cohens d). The type of residence was found to be an effect moderator. A positive intervention effect was found as well on work routines, with an average increase of 7.1 percentage points on a self-assessment scale among residences in the intervention group (P=0.016). No significant effects were found on BMI, waist circumference, dietary quality, or satisfaction with life. In conclusion, this innovative intervention was effective in improving physical activity and work routines. It is likely that even greater effects could be achieved by improvements in implementation strategies, leading to higher fidelity.

Promoting a healthy diet and physical activity in adults with intellectual disabilities living in community residences: Design and evaluation of a cluster-randomized intervention

BackgroundMany adults with intellectual disabilities have poor dietary habits, low physical activity and weight disturbances. This study protocol describes the design and evaluation of a health intervention aiming to improve diet and physical activity in this target group. In Sweden, adults with intellectual disabilities often live in community residences where the staff has insufficient education regarding the special health needs of residents. No published lifestyle interventions have simultaneously targeted both residents and staff.Methods/DesignThe intervention is designed to suit the ordinary work routines of community residences. It is based on social cognitive theory and takes 12-15 months to complete. The intervention includes three components: 1) Ten health education sessions for residents in their homes; 2) the appointment of a health ambassador among the staff in each residence and formation of a network; and 3) a study circle for staff in each residence. The intervention is implemented by consultation with managers, training of health educators, and coaching of health ambassadors. Fidelity is assessed based on the participation of residents and staff in the intervention activities. The study design is a cluster-randomised trial with physical activity as primary outcome objectively assessed by pedometry. Secondary outcomes are dietary quality assessed by digital photography, measured weight, height and waist circumference, and quality of life assessed by a quality of life scale. Intermediate outcomes are changes in work routines in the residences assessed by a questionnaire to managers. Adults with mild to moderate intellectual disabilities living in community residences in Stockholm County are eligible for inclusion. Multilevel analysis is used to evaluate effects on primary and secondary outcomes. The impact of the intervention on work routines in community residences is analysed by ordinal regression analysis. Barriers and facilitators of implementation are identified in an explorative qualitative study through observations and semi-structured interviews.DiscussionDespite several challenges it is our hope that the results from this intervention will lead to new and improved health promotion programs to the benefit of the target group.Trial registration numberISRCTN33749876
