The prognosis for individuals on disability retirement An 18-year mortality follow-up study of 6887 men and women sampled from the general population

BackgroundSeveral studies have shown a markedly higher mortality rate among disability pensioners than among non-retired. Since most disability pensions are granted because of non-fatal diseases the reason for the increased mortality therefore remains largely unknown. The aim of this study was to evaluate potential explanatory factors.MethodsData from five longitudinal cohort studies in Sweden, including 6,887 men and women less than 65 years old at baseline were linked to disability pension data, hospital admission data, and mortality data from 1971 until 2001. Mortality odds ratios were analyzed with Poisson regression and Coxs proportional hazards regression models.Results1,683 (24.4%) subjects had a disability pension at baseline or received one during follow up. 525 (7.6%) subjects died during follow up. The subjects on disability pension had a higher mortality rate than the non-retired, the hazards ratio (HR) being 2.78 (95%CI 2.08–3.71) among women and 3.43 (95%CI 2.61–4.51) among men. HR was highest among individuals granted a disability pension at young ages (HR >7), and declined parallel to age at which the disability pension was granted. The higher mortality rate among the retired subjects was not explained by disability pension cause or underlying disease or differences in age, marital status, educational level, smoking habits or drug abuse. There was no significant association between reason for disability pension and cause of death.ConclusionSubjects with a disability pension had increased mortality rates as compared with non-retired subjects, only modestly affected by adjustments for psycho-socio-economic factors, underlying disease, etcetera. It is unlikely that these factors were the causes of the unfavorable outcome. Other factors must be at work.

Sick-leave track record and other potential predictors of a disability pension. A population based study of 8,218 men and women followed for 16 years

BackgroundA number of previous studies have investigated various predictors for being granted a disability pension. The aim of this study was to test the efficacy of sick-leave track record as a predictor of being granted a disability pension in a large dataset based on subjects sampled from the general population and followed for a long time.MethodsData from five ongoing population-based Swedish studies was used, supplemented with data on all compensated sick leave periods, disability pensions granted, and vital status, obtained from official registers. The data set included 8,218 men and women followed for 16 years, generated 109,369 person years of observation and 97,160 sickness spells. Various measures of days of sick leave during follow up were used as independent variables and disability pension grant was used as outcome.ResultsThere was a strong relationship between individual sickness spell duration and annual cumulative days of sick leave on the one hand and being granted a disability pension on the other, among both men and women, after adjustment for the effects of marital status, education, household size, smoking habits, geographical area and calendar time period, a proxy for position in the business cycle. The interval between sickness spells showed a corresponding inverse relationship. Of all the variables studied, the number of days of sick leave per year was the most powerful predictor of a disability pension. For both men and women 245 annual sick leave days were needed to reach a 50% probability of transition to disability. The independent variables, taken together, explained 96% of the variation in disability pension grantings.ConclusionThe sick-leave track record was the most important predictor of the probability of being granted a disability pension in this study, even when the influences of other variables affecting the outcome were taken into account.

Sickness absence and self-reported health a population-based study of 43,600 individuals in central Sweden

BackgroundSickness absence is very high in Sweden. The reasons for this phenomenon are not well known. The aim of this study was to investigate the association between degree of self-reported sickness absence and health. The hypothesis was that individuals with long-term sickness absence would report more symptoms and lower self-rated health. Another hypothesis was that women are more likely to self-rate psychiatric diagnoses compared to men, who are more likely to self-rate musculoskeletal diagnoses.MethodsThe data was obtained with a postal survey questionnaire answered by 43,589 individuals, a Swedish random population sample of men and women aged 18–84 years. The response rate was 65%. This study included 19,826 individuals aged 18–64 years old and still at work. They were divided into four groups, based on the number of reported days of sickness absence during the past year.ResultsApproximately 40% of the individuals at work mentioned that they had been absent due to illness sometime during the past year. Of those who had been absent 90 days or more, two thirds were women. There was a significant difference between the groups in self-rated health (p < 0.05). Every fifth woman (19.4%) and every fourth man (25.9%) in the group with a sickness absence of more than 89 days rated their health as poor or very poor, but a large proportion, 43.5% of the women and 31.6% of the men, rated their health as good. Long-term illnesses and complaints differed between the groups. The correlations between the groups and illness were mostly significant (p < 0.01). Two thirds of the subjects had both psychiatric and musculoskeletal symptoms. There was a significant difference among them, as men more often had musculoskeletal diagnoses. One third had only psychiatric or musculoskeletal symptoms and in those groups there were no significant diagnosis differences between the sexes.ConclusionIndividuals with long-term sickness absence reported more symptoms and lower self-rated health than did those who had not been absent at all, and than those who had been ill 1–28 days. Men and women sick-listed 29 days or more generally reported more illness and complaints. No sex differences among psychiatric and musculoskeletal diagnoses were found, but when reported both psychiatric and musculoskeletal symptoms the musculoskeletal diagnoses were significant among men.

Effects of self-rated health on sick leave, disability pension, hospital admissions and mortality. A population-based longitudinal study of nearly 15,000 observations among Swedish women and men

BackgroundSimple global self-ratings of health (SRH) have become increasingly used in national and international public health monitoring, and in recent decades recommended as a standard part of health surveys. Monitoring developments in population health requires identification and use of health measures, valid in relation to targets for population health. The aim of the present study was to investigate associations between SRH and sick leave, disability pension, hospital admissions, and mortality, adjusted for effects of significant covariates, in a large population-based cohort.MethodsThe analyses were based on screening data from eight population-based cohorts in southern and central Sweden, and on official register data regarding sick-leave, disability pension, hospital admissions, and death, with little or no data loss. Sampling was performed 1973–2003. The study population consisted of 11,880 women and men, age 25–99 years, providing 14,470 observations. Information on SRH, socio-demographic data, lifestyle variables and somatic and psychological symptoms were obtained from questionnaires.ResultsThere was a significant negative association between SRH and sick leave (Beta −13.2, p<0.0001, and −9.5, p<0.01, in women and men, respectively), disability pension (Hazard ratio 0.77, p<0.0001 and 0.76, p<0.0001, in women and men, respectively), and mortality, adjusted for covariates. SRH was also significantly associated with hospital admissions in men (Hazard ratio 0.87, p<0.0001), but not in women (Hazard ratio 0.96, p0.20). Associations between SRH on the one hand, and sick leave, disability pension, hospital admission, and mortality, on the other, were robust during the follow-up period.ConclusionsSRH had strong predictive validity in relation to use of social insurance facilities and health care services, and to mortality. Associations were strong and robust during follow-up.

Losing independence – the lived experience of being long-term sick-listed

BackgroundSickness absence is a multifaceted problem. Much is known about risk factors for being long-term sick-listed, but there is still little known about the various aftermaths and experiences of it. The aim of this qualitative study was to describe, analyze and understand long-term sickness-absent people’s experiences of being sick-listed.MethodsThe design was descriptive and had a phenomenological approach. Sixteen long-term sickness-absent individuals were purposively sampled from three municipalities in Sweden in 2011, and data were collected through semi-structured, individual interviews. The interview questions addressed how the participants experienced being sick-listed and how the sick-listing affected their lives. Transcribed interviews were analysed using Giorgis phenomenological method.ResultsThe interviews revealed that the participants’ experiences of being sick-listed was that they lost their independence in the process of stepping out of working society, attending the mandatory steps in the rehabilitation chain and having numerous encounters with professionals. The participants described that their life-worlds were radically changed when they became sick-listed. Their experiences of their changing life-worlds were mostly highly negative, but there were also a few positive experiences. The most conspicuous findings were the fact that stopping working brought with it so many changes, the participants’ feelings of powerlessness in the process, and their experiences of offensive treatment by and/or encounters with professionals.ConclusionsSick-listed persons experienced the process of being on long-term sickness absent as very negative. The negative experiences are linked to consequences of stopping to work, consequences of social insurance rules and to negative encounters with professionals handling the sickness absence. The positive experiences of being sick-listed were few in the present study. There is a need to further examine the extent of these negative experiences are and how they affect sick-listed people’s recovery and return to work.

Health care utilisation before and after retirement due to illness. A 13-year population-based follow-up study of prematurely retired men and referents from the general population.

OBJECTIVE To test the hypothesis that prematurely retired men have long-term unspecifically increased health care utilisation, indicating broader health deterioration than reflected by the retirement diagnosis. DESIGN A two-cohort study. SETTING The City of Eskilstuna, Sweden. SUBJECTS 215 men aged 30-54 years who retired early due to illness and a random sample of 620 referents of the same age from the general population. MAIN OUTCOME MEASURES Health care utilisation from 5 years before retirement until 13 years after retirement. RESULTS The retired men had 7.2 times higher utilisation of primary health care during the baseline year and 2-3 times higher rates of hospital admissions than the referents during the 13-year follow-up. The panorama of main hospital discharge diagnoses was the same among retired men and referents irrespective of the retirement diagnoses of the former. Over time, health care utilisation among the retired men decreased, but was constant among the referents. After 13 years, the retired men still had twice the rate of the referents. CONCLUSION Prematurely retired men had high health care utilisation also after retirement. They appear to have broader health deterioration than reflected by the retirement diagnosis.

Novel insights into the interplay between ventral neck muscles in individuals with whiplash-associated disorders

Chronic whiplash-associated disorder (WAD) is common after whiplash injury, with considerable personal, social, and economic burden. Despite decades of research, factors responsible for continuing pain and disability are largely unknown, and diagnostic tools are lacking. Here, we report a novel model of mechanical ventral neck muscle function recorded from non-invasive, real-time, ultrasound measurements. We calculated the deformation area and deformation rate in 23 individuals with persistent WAD and compared them to 23 sex- and age-matched controls. Multivariate statistics were used to analyse interactions between ventral neck muscles, revealing different interplay between muscles in individuals with WAD and healthy controls. Although the cause and effect relation cannot be established from this data, for the first time, we reveal a novel method capable of detecting different neck muscle interplay in people with WAD. This non-invasive method stands to make a major breakthrough in the assessment and diagnosis of people following a whiplash trauma.

Determinants for return to work among sickness certified patients in general practice

BackgroundLong-term sickness absence is one of the main risk factors for permanent exit out of the labour market. Early identification of the condition is essential to facilitate return to work. The aim of this study was to analyse possible determinants of return to work and their relative impact.MethodsAll 943 subjects aged 18 to 63 years, sickness certified at a Primary Health Care Centre in Sweden from 1 January until 31 August 2004, were followed up for three years. Baseline information on sex, age, sick leave diagnosis, employment status, extent of sick leave, and sickness absence during the year before baseline was obtained, as was information on all compensated days of sick leave, disability pension and death during follow-up.ResultsSlightly more than half the subjects were women, mean age was 39 years. Half of the study population returned to work within 14 days after baseline, and after three years only 15 subjects were still on sick leave. In multivariate proportional hazards regression analysis the extent of previous sick leave, age, being on part-time sick leave, and having a psychiatric, musculoskeletal, cardiovascular, nervous disease, digestive system, or injury or poisoning diagnosis decreased the return to work rate, while being employed increased it. Marital status, sex, being born in Sweden, citizenship, and annual salary had no influence. In logistic regression analyses across follow-up time these variables altogether explained 88-90% of return to work variation.ConclusionsReturn to work was positively or negatively associated by a number of variables easily accessible in the GP’s office. Track record data in the form of previous sick leave was the most influential variable.

The Effect of 3 Different Exercise Approaches on Neck Muscle Endurance, Kinesiophobia, Exercise Compliance, and Patient Satisfaction in Chronic Whiplash

OBJECTIVE The purpose of this study was to compare the effects of 3 different exercise approaches on neck muscle endurance (NME), kinesiophobia, exercise compliance, and patient satisfaction in patients with chronic whiplash. METHODS This prospective randomized clinical trial included 216 individuals with chronic whiplash. Participants were randomized to 1 of 3 exercise interventions: neck-specific exercise (NSE), NSE combined with a behavioral approach (NSEB), or prescribed physical activity (PPA). Measures of ventral and dorsal NME (endurance time in seconds), perceived pain after NME testing, kinesiophobia, exercise compliance, and patient satisfaction were recorded at baseline and at the 3- and 6-month follow-ups. RESULTS Compared with individuals in the prescribed physical activity group, participants in the NSE and NSEB groups exhibited greater gains in dorsal NME (P = .003), greater reductions in pain after NME testing (P = .03), and more satisfaction with treatment (P < .001). Kinesiophobia and exercise compliance did not significantly differ between groups (P > .07). CONCLUSION Among patients with chronic whiplash, a neck-specific exercise intervention (with or without a behavioral approach) appears to improve NME. Participants were more satisfied with intervention including neck-specific exercises than with the prescription of general exercise.

Altered ventral neck muscle deformation for individuals with whiplash associated disorder compared to healthy controls : A case-control ultrasound study

Previous studies have shown altered neck muscle function in individuals with chronic whiplash associated disorder (WAD). However, we lack real-time investigations with non-invasive methods that can distinguish between the different ventral neck muscle layers. This study investigated deformations and deformation rates in the sternocleidomastoid (SCM), longus capitis (Lcap), and longus colli (Lco) muscles with real-time ultrasonography. Twenty-six individuals with WAD were compared with 26 controls, matched for age and sex. Ultrasound imaging of the SCM, Lcap, and Lco were recorded during 10 repetitive arm elevations. The first and tenth arm elevations were post-process analyzed with speckle tracking. There were few significant differences in the deformations or deformation rates in the SCM, Lcap, and Lco between the WAD and control group. In controls, deformations and deformation rates showed linear positive relationships between SCM/Lcap, SCM/Lco, and Lcap/Lco which increased from the first arm elevation (R(2) = 0.14-0.70); to the tenth arm elevation (R(2) = 0.51-0.71). The WAD group showed similar or weaker linear relationship (R(2) < 0.19) during the tenth compared to the first (R(2) < 0.44) arm elevation except for deformations in Lcap/Lco (R(2) = 0.13-0.57). This result indicated that deformations and deformation rates in one muscle were correlated by similar deformations and deformation rates in other neck muscles in the control group, but this interplay between muscles was not found in the WAD group.
