Readiness for return to work following injury or illness: conceptualizing the interpersonal impact of health care,workplace, and insurance factors

Return to work after injury or illness is a behavior influenced by physical, psychological, and social factors. Disability research lacks a conceptual framework for combining these factors in the study of the return-to-work process. Two extant theoretical models withinthe social context are considered as they apply to the behavior of returning to work: 1) the Readiness for Change Model originating from the field of health promotion and addressing the issue of motivation for behavior change, and 2) the Phase Model of Disability developed for the epidemiological study of occupational disability addressing the developmental and temporal aspects of disability. A new Readiness for Return-to-Work Model is proposed focusing on the interpersonal context of the work-disabled employee. Employee interactions with the workplace, the health care, and insurance systems are considered as they impact the three defining dimensions of change—decisional balance, self-efficacy, and change processes. The evidence for their impact on return-to-work is examined within the framework of the Phase Model of Disability, which puts forth the phase-specificity of symptoms, risks, and interventions for disability. The Readiness for Return-to-Work Model has the potential to account for individual variation in optimal stage-specific timing of interventions based on an individual's readiness for return-to-work. The model therefore complements the Phase Model of Disability by allowing for an individual-level staging of the disability and recovery process within the broader group-level-derived framework of occupational disability phases. This link between the two models needs to be empirically tested in future research.

A prospective study of limiting longstanding illness in early adulthood

BACKGROUND: Chronic illness and disability are of increasing public health importance but little is known about the lifetime influences involved in their onset and progression. We aim to (i) establish whether an individual's rating of limiting illness is stable over a 10-year period from age 23 to 33; (ii) assess the relationship between childhood and adult disability; and (iii) identify lifecourse influences on limiting illness in early adulthood. METHODS: Data were from the 1958 British birth cohort, including the original birth survey and follow-ups at ages 7, 11, 16, 23 and 33 years. Limiting longstanding illness was the outcome at both ages 23 and 33. Potential predictors included childhood health and physical development, socioeconomic conditions in early life and adulthood, and behavioural factors. We estimated the effect of potential explanatory factors using logistic regression, in both univariate and multivariate analyses, separately for limiting illness at 23 and 33 years. RESULTS: Prevalence of limiting illness increased from 5.1% (men) and 4.1% (women) at age 23 to 6% for both sexes at age 33. Risk of limiting illness at age 33 was greater for those reporting an illness at age 23 (29.4%, compared with 4.7% of those without illness), though the majority (66%) of 33-year limiting illnesses had no previous record at age 23 or for childhood. Multivariate analysis of limiting illness at age 23 confirmed the high risk for those with childhood disability and also established two further major predictors, namely, injury (adjusted odds ratio [OR] = 1.42, 95% CI: 1.09-1.86) and intermediate socio-emotional status (adjusted OR = 1.73, 95% CI: 1.29-2.31). Additional risks were identified for limiting illness at age 33, including: (i) injury in the preceding 10 years (adjusted OR = 1.55, 95% CI : 1.18-2.04); (ii) body mass index (BMI), for which the relationship was non-linear, with elevated risks for the underweight (adjusted OR = 1.53, 95% CI: 1.03-2.26) and overweight (OR = 1.28, 95% CI: 0.87-1.89); (iii) childhood disadvantage at either or both ages 7 and 11 (adjusted OR = 1.53, 95% CI : 1.07-2.17); and (iv) height at age 7, with a significant non-linear relationship (the adjusted OR for height less than 15th percentile was 1.43 and for height more than the 85th percentile, 1.30). CONCLUSIONS: Both childhood and adult factors predict limiting illness in early adulthood. Childhood is important because some adult illnesses originate in early life, and also because childhood environment influences the risk of adult limiting illness several years later. Our findings suggest that studies seeking to understand the causes of limiting illness, that currently tend to focus exclusively on contemporary factors, need also to consider the contribution of environment in early life.     

Disability in young adults: the role of injuries.

STUDY OBJECTIVES--To describe the prevalence of disability in young adults and estimate the contribution that injuries make to disability. DESIGN--The study uses data from a British longitudinal survey, the National Child Development Study (1958 cohort). Disability at age 23 was ascertained from three questions asked in an interview with cohort members in 1981: these related to longstanding illness that limits activity, permanent disability following an accident after age 16, and registered disability. Lower and upper estimates of the contribution of injuries to disability were derived from ICD-9 codes allocated to the disabilities. SUBJECTS--These comprised 12,537 subjects, representing 76% of the target population, cohort members still alive and resident in Britain in 1981. MAIN RESULTS--Prevalence of disability according to the three definitions was: 46 per 1000 with limiting longstanding illness; 28 per 1000 with a permanent accident related disability of onset after age 16; and 10 per 1000 registered disabled. Combining all three definitions, the overall prevalence of disability was 68 per 1000, with men reporting more disability than women. It was estimated that an injury caused the disability for 16.7% of subjects, at the lower estimate, and 26.0% at the upper estimate (23.1% to 32.1% for men and 8.6% to 18.4% for women). For limiting longstanding illness of onset after 16, between 33.5% and 47.8% was due to an injury. Road accidents caused 31% of permanent accident related disability. Over one half of men and nearly three quarters of women reporting permanent accident related disability had not been admitted to hospital for their injury. CONCLUSIONS--Injuries are an important cause of disability in young adults, particularly injuries resulting from accidents after age 16. Accident prevention in the 16-24 group has the potential to reduce the prevalence of disability substantially.     

Sexuality, Identity and Women with Spinal Cord Injury

Sexuality is an integral component of every individual’s identity. The literature offers limited information about the sexuality and sexual identity of women with spinal cord injury (SCI), beyond the physiological and neurological aspects. The qualitative study described in this paper aimed to explore the experiences and perceptions of a small sample of adult women with SCI regarding their sexuality post-injury. Semi-structured interviews were conducted with four women, which were audio-taped and then transcribed. Thematic analysis was adopted for analyzing the narrative data. Themes that were identified include: factors facilitating positive sexual adjustment, barriers to sexuality post-injury and lack of sexual education in the rehabilitation process. Women with SCI echoed the need to be recognized as sexual beings, despite disability. Health professionals must be willing to discuss issues of a sexual nature and need an understanding of how illness or disability may impact on sexuality, in order to adequately assist individuals with physical disabilities address sexual and intimacy issues.     

Quantifying social consequences of occupational injuries and illnesses: state of the art and research agenda

BACKGROUND: Quantitative methods for describing the social effects of occupational injury and illness are evaluated including surveys of prevalence and ratings of severity of social role disability. METHODS: The reliability and validity for the injured worker population of the most commonly used general and condition-specific role disability measures is reviewed and summarized. This review is used to support the development of a prototype strategy for quantifying the social consequences of occupational injuries and to identify areas of need for further research and development. CONCLUSIONS: Research is needed to: (a) determine which of existing measures is most precise in describing the severity of dysfunction due to a specific illness or injury, (b) expand the development of measures of specific role functioning (including paid work), and (c) develop item banks to support the construction of computer adaptive assessments of role functioning.     

The error of using returns-to-work to measure the outcomes of health care

This article uses data from The Survey of Ontario Workers With Permanent Impairments, the world's largest survey of injured workers, to show that, as currently used, return-to-work is a misleading measure of the effectiveness of health care. The article discusses examples of two serious limitations on the use of return-to-work to measure the outcomes of health care, where health care refers to all the medical and rehabilitative services provided to a worker following a workplace injury. The first limitation is that return-to-work, like many other outcomes of health care, is influenced by factors that are not directly related to health care. Using a logit model to estimate the determinants of first absences from work after an injury, we find that socioeconomic characteristics, economic incentives, and job characteristics have a significant influence on return-to-work. The second limitation on return-to-work as an outcome measure is that the first return-to-work after an injury, like a hospital discharge, frequently marks the end of only the first of several episodes of work disability caused by the original injury. Using first post-injury returns-to-work as a proxy for recovery, we would assume that 85% of the Ontario workers recovered from their injury when, in fact, 61% had subsequent spells of work disability. We identified four mutually exclusive patterns of post-injury work and work disability. Multinomial logit estimates of the determinants of the patterns show that health care is only one of several influences on return-to-work. The results also demonstrate that if return-to-work is used to measure outcomes, it must be evaluated over a time horizon that permits multiple spells of work disability. © 1996 Wiley-Liss, Inc.     

Underreporting of work-related injury or illness to workers' compensation: individual and industry factors

OBJECTIVE: We quantified the underreporting of work-related injury or illness to workers' compensation (WC). METHODS: Using data from 2612 wage-earning respondents who participated in the 2002 Washington State Behavioral Risk Factor Surveillance System, we assessed work-related injury or illness in the previous year and identified the factors associated with WC claim filing by logistic regression. RESULTS: The self-reported rate of work-related injury or illness of respondents was 13%. Among those who had a work-related injury or illness, 52% filed a WC claim. After adjustment for age, gender, and race, those who filed WC claims were more likely to be overweight and married. WC claim filing varies considerably across industry and occupation groups holding all other measured factors constant. CONCLUSIONS: Individual and industry/occupation factors are related to underreporting of work-related injury or illness to the WC system.

Association between workers’ compensation claim processing times and work disability duration: Analysis of population level claims data

Delays in workers’ compensation claim processing (CP) times have been associated with reduced recovery and delayed return-to-work. This study aimed to (1) determine the injury, worker, and workplace factors associated with CP delays and (2) investigate whether CP delays are associated with longer disability duration after adjusting for these factors. Retrospective cohort analysis of Australian workers’ compensation claims was conducted from 1st July 2009 to 30th June 2016 for objective (1) and to 30th June 2014 for objective (2). CP times were derived by calculating differences in days between: injury and lodgement dates (lodgement); lodgement and decision dates (decision) and; injury and decision dates (total). All CP times were shorter for younger workers and those with fractures or traumatic injury, and longer for those with neurological or mental health conditions, and other diseases. Claims from self-insured employers had shorter decision times. With increasing lodgement, decision and total time there was significantly higher hazard of longer disability duration. Findings suggest the need for more efficient claims management to ensure fewer barriers to claim lodgement or approval. This in turn should reduce disability duration and ensure improved return-to-work outcomes.     

Baseline chronic disease risk factors in a racially heterogeneous elementary school population: The "Know Your Body" program, Los Angeles

The Los Angeles "Know Your Body" (KYB) program is an organized health education activity for children designed to encourage positive health behavior and discourage or interrupt behavioral patterns that are linked to illness, injury, disability, or death. Components of KYB include a 20-week curriculum; a survey of health knowledge, attitudes, and behaviors; in-service training for elementary school teachers; and a clinical screening that provides feedback to students on selected indices. As part of a KYB field demonstration in Los Angeles conducted by the UCLA Division of Cancer Control, Jonsson Comprehensive Cancer Center, 1,503 Los Angeles and Santa Monica-Malibu children ages 9-11 in grades 4 and 5 underwent baseline health screening evaluations in March 1981, measuring height, weight, triceps skinfold thickness, serum cholesterol, pulse rate recovery following exercise, and blood pressure. The population mean for serum cholesterol was 182.6 mg/dl, with no significant racial/ethnic, sex, or age differences. Significant racial/ethnic differences were found in obesity, with Hispanics having the highest prevalence, Asians the lowest. Black students scored significantly higher in pulse rate recovery following exercise, suggesting better relative cardiovascular fitness, and Asians scored lowest. Blacks were more likely to exceed the 95th percentile in diastolic and systolic blood pressure. Overall, 48% of the children had one or more chronic disease risk factors.     

Risk and severity of non-back occupational injuries after lumbar laminectomy for degenerative disc disease

An increased risk, after lumbar laminectomy, for lost work time occupational back injury (odds ratio, 5.9; 95% confidence interval, 1.9-18.8) and disability (mean 292.8 days vs. 24.8 for controls) was previously demonstrated. Such differences could be due to physical sequelae of back surgery or to psychosocial factors. Extensive literature addresses the impact of psychosocial factors on the incidence of occupational injury and severity of disability. This study assumes that psychosocial factors would affect both back and non-back injuries, while surgery-related physical factors would not. The odds ratio for non-back lost work time injury for subjects in the same cohort studied previously was 1.5 (0.5-4.5), with no significant increase in duration of disability (mean 27.0 days vs. 24.8 for controls). The increased risk for back injury in the absence of an increased risk for other injuries suggests that physiologic rather than psychosocial factors provide the more likely explanation for the differences in back injuries.     

What every physician needs to know about disability insurance

Physicians and their patients rely on disability insurance to provide economic protection against unforeseen illness or injury. This article discusses various types of disability coverage and issues that arise in disability claims both from the perspective of the physician as treater as well as consumer.     

On the Downplay of Suffering in Nordenfelt’s Theory of Illness

In his influential theory of health Nordenfelt bases the concepts of health and illness on the notions of ability and disability. A premise for this is that ability and disability provide a more promising, adequate, and useful basis than well-being and suffering. Nordenfelt uses coma and manic episodes as paradigm cases to show that this is so. Do these paradigm cases (and thus the premise) hold? What consequences does it have for the theory of health and illness if it they do not? These are the key questions in this article, which first presents the relationship between pain and disability in Nordenfelt’s theory and the paradigm cases he uses to argue for the primacy of disability over pain. Then, Nordenfelt’s concepts of illness are outlined, highlighting its presumptions and arguments. The main point is that if you do not have an action-theoretical perspective, it is not obvious that disability is the core concept for illness. The compelling effect of the paradigm cases presupposes that you see ability as the primary issue. To those who do not share this presumption, people in coma may not be ill. There are alternative well founded arguments for the primacy of first person experiences for the concept of illness. Hence, we need better arguments for the primacy of disability over first person experiences in illness, or first-person experience should be more primarily included in the concept of illness.     

Occupational impairment and disability among applicants for Social Security disability benefits in Pennsylvania.

OBJECTIVE. The study goal was to assess the extent of workplace-related disease and injury among Social Security Disability Insurance applicants. METHODS. A convenience sample of 240 consecutive applicants to the Pennsylvania Bureau of Disability Determination was studied to assess the prevalence of work-related disorders. An applicant had a work-related condition if there was a clear statement of a workplace illness or injury associated with the impairment, or if the applicant had worked at an occupation with a high likelihood of exposures known or suspected to contribute to the condition of interest. RESULTS. Of the 240 applicants, 166 (69%) were awarded disability insurance benefits; a total of 27 (11%) had work-related conditions, including 14 of the 166 (8%) who were found to be disabled. Forty percent of the 27 had a disorder that was musculoskeletal in origin. Of 59 applicants with cancer, 10.2% had some work-related etiological component. Of an estimated 71,680 adult disability insurance applicants in Pennsylvania in 1990, 5134 new insurance beneficiaries had a projected occupationally related disability. CONCLUSIONS. A substantial number of applicants for disability insurance benefits suffer from an impairment caused or exacerbated by prior workplace exposures. These individuals may serve as sentinel events for initiating follow-up surveillance and prevention activities.     

Effects of illness and disability on job separation

Effects of illness and disability on job separation result from both voluntary and involuntary processes. Voluntary processes range from the reasoned actions of workers who weigh illness and disability in their decision-making, to reactive stress-avoidance responses. Involuntary processes include employer discrimination against ill or disabled workers. Analyses of the effects of illness and disability that differentiate reasons for job separation can illuminate the processes involved. This paper reports on an evaluation of effects of illness and disability on job separation predicted by theories of reasoned action, stress, and employer discrimination against ill and disabled workers. Effects of four illness/disability conditions on the rate of job separation for 12 reasons are estimated using data from a longitudinal study of a representative sample of the Canadian population-the Survey of Labour and Income Dynamics (SLID). Two of the four effects that are statistically significant (under conservative Bayesian criteria for statistical significance) are consistent with the idea that workers weigh illness and disability as costs, and calculate the costs and benefits of continuing to work with an illness or disability: (1) disabling illness increases the hazard of leaving a job in order to engage in caregiving, and (2) work-related disability increases the hazard of leaving a job due to poor pay. The other two significant effects indicate that: (3) disabling illness decreases the hazard of layoff, and (4) non-work disability increases the hazard of leaving one job to take a different job. This last effect is consistent with a stress-interruption process. Other effects are statistically significant under conventional criteria for statistical significance, and most of these effects are also consistent with cost-benefit and stress theories. Some effects of illness and disability are sex and age-specific, and reasons for the specificity of these effects are discussed.     

Injury morbidity in 18-64-year-olds: impact and risk factors

BACKGROUND: Non-fatal injury is an important public health problem but is thought to be difficult to quantify. This study aimed to estimate the extent of disability attributable to injury in the working age population, and its impact on quality of life, as well as identifying factors associated with an increased risk of disabling and non-disabling injury. METHODS: Secondary analysis was carried out of data obtained from a postal questionnaire survey of 8889 18-64-year-olds randomly selected from computerized general practitioner records in Oxfordshire, Buckinghamshire, Berkshire and Northamptonshire. RESULTS: Sixteen per cent of survey respondents reported an injury requiring medical attention in the previous 12 months, 5 per cent reported an injury that had disabled them for more than 1 month, and a further 5 per cent a longstanding disability as a result of injury. The point prevalence of disability as a result of injury was estimated to be 6.4 per cent. SF-36 scores suggest that the quality of life of people reporting injury-related disability was markedly reduced. Social class is associated less with injury morbidity than with injury mortality. Sport was the commonest cause of all injuries, and of disabling injuries. There was a dose-response relationship between vigorous exercise and injury. CONCLUSIONS: Injury is a significant cause of disability in the working age population. It is potentially feasible to monitor injury-related disability in postal questionnaire surveys. Estimates of health gain to be achieved from participation in sport should take account of injury-related disability.     

Adolescent injury risk behavior

Health-risk behaviors that contribute to the leading causes of morbidity and mortality among adolescents and young adults are often established during adolescence and extended into adulthood. Unintentional motor vehicle injury is the leading cause of mortality in childhood and adolescence in developed countries. This review presents some of the risk factors found in research on unintentional injury and death in adolescence, including risk factors for siblings and adolescents with intellectual disability. These findings should be connected with the findings of a recent study that showed that about one third of all unintentional childhood injury deaths in the United States were preventable. For injury prevention to take place and being effective a multidisciplinary approach is needed to identify host, agent and environmental factors using epidemiology research and biomechanics. In the population of adolescents with intellectual disability there has been little research on injury epidemiology or injury prevention and the service provider will need to focus and educate staff on this issue in order to prevent injury that can result in further disability.     

Preventing injury, illness and disability at work

This discussion paper is intended to start a dialogue about prevention among those who are interested in making workplaces safer and healthier. The following four key themes are presented to build a framework for further discussion and activity: theme 1 -- with multiple causes for workplace injury, illness, and disability, preventing these problems requires multiple solutions, operating in synergy; theme 2 -- efforts to reduce workplace injury, illness, and disability must build on both primary and secondary prevention approaches, merging these to create a more effective strategy; theme 3 -- before which strategies work and which do not can be agreed upon, a shared understanding is needed of how the effectiveness of occupational health interventions should be evaluated; and theme 4 -- building relationships between those who do research and those who use research knowledge is important if relevant research is to be produced that is readily taken up and applied to improve occupational health and safety.
