Implementation of Early Intervention Protocol in Australia for 'High Risk' Injured Workers is Associated with Fewer Lost Work Days Over 2 Years Than Usual (Stepped) Care.

Purpose To evaluate whether a protocol for early intervention addressing the psychosocial risk factors for delayed return to work in workers with soft tissue injuries would achieve better long-term outcomes than usual (stepped) care. Methods The study used a controlled, non-randomised prospective design to compare two case management approaches. For the intervention condition, workers screened within 1-3 weeks of injury as being at high risk of delayed returned to work by the Örebro Musculoskeletal Pain Screening Questionnaire-short version (ÖMPSQ-SF) were offered psychological assessment and a comprehensive protocol to address the identified obstacles for return to work. Similarly identified injured workers in the control condition were managed under usual (stepped) care arrangements. Results At 2-year follow-up, the mean lost work days for the Intervention group was less than half that of the usual care group, their claim costs were 30% lower, as was the growth trajectory of their costs after 11 months. Conclusions The findings supported the hypothesis that brief psychological risk factor screening, combined with a protocol for active collaboration between key stakeholders to address identified psychological and workplace factors for delayed return to work, can achieve better return on investment than usual (stepped) care.

Predicting Return to Work in a Heterogeneous Sample of Recently Injured Workers Using the Brief ÖMPSQ-SF.

Purpose (1) to examine the ability of the Örebro Musculoskeletal Pain Screening Questionnaire-short version (ÖMPSQ-SF) to predict time to return to pre-injury work duties (PID) following a work-related soft tissue injury (regardless of body location); and (2) to examine the appropriateness of 50/100 as a suitable cut-off score for case identification. Methods Injured workers (IW) from six public hospitals in Sydney, Australia, who had taken medically-sanctioned time off work due to their injury, were recruited by insurance case managers within 5-15 days of their injury. Eligible participants (N = 213 in total) were administered the ÖMPSQ-SF over the telephone by the case manager. For objective (1) Cox proportional hazards regression analysis was used to predict days to return to PID using the ÖMPSQ-SF. For objective (2) receiver operator characteristic (ROC) analysis was used to determine the ÖMPSQ-SF total score that optimises sensitivity and specificity in detecting whether or not participants had returned to PID within 2-7 weeks. Results The total ÖMPSQ-SF score significantly predicted number of days to return to PID, such that for every 1-point increase in the total ÖMPSQ-SF score the predicted chance of returning to work reduced by 4% (i.e., hazard ratio = 0.96), p < 0.001. Sensitivity and specificity for the ROC analysis comparing ÖMPSQ-SF total score to return to PID within 2-7 weeks suggested 48 as the optimal cut off (sensitivity = 0.65, specificity = 0.79). Conclusion The results provide strong support for the use of the ÖMPSQ-SF in an applied setting for identifying those IW likely to have delayed RTW when administered within 15 days of the injury. While a score of 48/100 was the optimal cut point for sensitivity and specificity, pragmatically, 50/100 should be acceptable as a cut-off in future studies of this type.

Implementation of the Participatory Approach for Supervisors to Increase Self-Efficacy in Addressing Risk of Sick Leave of Employees: Results of a Cluster-Randomized Controlled Trial.

Purpose To study the effectiveness of a multifaceted strategy to implement the participatory approach (PA) for supervisors to increase their self-efficacy in addressing risk of sick leave of employees. Methods Supervisors from three organizations were invited to participate. Randomization was performed at department level. Supervisors (n = 61) in the intervention departments received the implementation strategy consisting of a working group meeting, supervisor training in PA application, and optional supervisor coaching. Supervisors in the control departments (n = 55) received written information on PA. The primary outcome was supervisors' self-efficacy to apply the PA, measured at baseline and 6 months' follow-up. The number of employees with whom supervisors discussed work functioning problems or (risk of) sick leave was also assessed. Effects were tested using multilevel analyses. Results The strategy did not increase self-efficacy to apply the PA. Subgroup analyses showed that self-efficacy increased for supervisors who at baseline reported to have discussed (risk of) sick leave with less than three employees during the last 6 months (B = 1.42, 95 % CI 0.34-2.50). Furthermore, the implementation strategy increased the number of employees with whom supervisors discussed work functioning problems or risk of sick leave (B = 1.26, 95 % CI 0.04-2.48). Conclusion Although the implementation strategy cannot be recommended for all supervisors, for supervisors who less frequently discuss (risk of) sick leave with employees the implementation strategy might be helpful.

Employees' Perceptions of Social Norms as a Result of Implementing the Participatory Approach at Supervisor Level: Results of a Randomized Controlled Trial.

Purpose A multifaceted implementation strategy was targeted at supervisors to encourage them to apply a participatory approach (PA) in dealing with employees' work functioning problems due to health concerns. This paper assesses the effect on employees' perceived social norms regarding the use of the PA to deal with work functioning problems. Methods Three organizations participated in a cluster randomized controlled trial, with randomization at the department level. Supervisors in the PA intervention departments received the implementation strategy consisting of a working group meeting, supervisor training, and optional coaching. Supervisors in the control departments received written information about the PA only. In two of the organizations, employees were invited to complete surveys at baseline and at 6-month follow-up. The primary outcome was perceived social norms regarding the use of the PA to deal with work functioning problems. Secondary measures included attitudes and self-efficacy, and intention regarding joint problem solving, and sick leave data. Effects were analyzed using multilevel analyses to account for nesting of cases. Results At baseline, 273 employees participated in the survey, with follow-up analyses of 174 employees. There were no statistically significant group effects on employee outcome measures. The intervention group showed a larger reduction in mean sick days (from 4.6 to 2.4 days) versus the control group (from 3.8 to 3.6 days), but this difference did not reach statistical significance (p > .05). Conclusion The multifaceted strategy to implement the participatory approach for supervisors did not show effects on outcomes at the employee level. To gain significant effects at the employee level, may require that an implementation strategy not only targets management and supervisors, but also employees themselves.

Self-reported social functioning among older patients with schizophrenia.

The purpose of this study was to evaluate the utility of a self-report measure of social functioning as an outcome measure for older schizophrenia patients. Sixty-five schizophrenia patients and 39 healthy controls, ranging in age from 45 to 81 years, were evaluated using a modified Social Adjustment Scale (SAS-M), Scales for Assessment of Positive and Negative Symptoms, Depression Subscale of the Brief Symptom Inventory, Mini-Mental State Examination, Dementia Rating Scale, measures of social support, and measures of background variables. Compared with controls, fewer patients with schizophrenia engaged in social roles, were married, were parents, or held jobs. Moreover, patients were more impaired in overall functioning, specifically in the domains of social/leisure, extended family, and marital roles than controls. Impairments in most roles were correlated with greater severity of symptoms, but not with degree of cognitive impairment, social environment, or background characteristics. The SAS-M is a useful addition to psychosocial batteries; however, the self-report format may not reflect others' perception of functioning.

Predicting health care use among older osteoarthritis patients in an HMO.

OBJECTIVE: To determine factors that predict health care use among members of Health Maintenance Organizations (HMOs). Demographic, health, and psychological factors were examined simultaneously. METHODS: Participants were HMO members 60 years of age or older who had osteoarthritis (OA). All participants reported symptoms of OA, with 90% of the diagnoses confirmed by evaluation of physician records. RESULTS: Age, the presence of other medical conditions, quality of well-being, and the Health Worries subscale from the Arthritis Impact Measurement Scales accounted for 11.2% of the total variance in health care contacts. A model including prior health care use, age, quality of well-being, physical impairment, and pain accounted for 29.5% of the variance in utilization rates. CONCLUSION: The best single predictor of health care utilization was prior use of the system. Being older, more impaired, and having lower well-being scores were also predictors of health care use.

Predictors of attrition in health intervention research among older subjects with osteoarthritis.

Attrition in an experimental osteoarthritis intervention was studied among 364 (130 male) volunteers (ages 60-87). Subjects were randomly assigned to control, social support, education, or combined treatment groups. A series of discriminant function analyses showed that the final intervention groups were more homogeneous than the original samples. The most robust predictor of attrition was having either high or very low depression scores. Social support variables were predictors of poor attendance in the social support group, indicating possible attrition bias in evaluating this treatment. The results indicate that psychosocial variables may be the best predictors of attrition in health intervention research among older subjects, and that variables related to attrition can be related to the content of the intervention.

Accelerated risk of hypertensive blood pressure recordings among Alzheimer caregivers.

The purpose of this study was to determine whether the stress of caregiving for the Alzheimer's disease (AD) patient accelerates the likelihood of exceeding hypertensive blood pressure (BP) criteria in periodic longitudinal home assessments. In this cohort study, participants consisted of spousal caregivers of AD patients (n = 144) and demographically equivalent non-caregiving controls (n = 47). Thirty percent of caregivers and 33% of controls were receiving antihypertensive treatment at study entry. Supine systolic and diastolic blood pressure (SBP and DBP) was assessed by semi-automated recordings taken in the home every 6 months for 2 to 6 years. Survival analyses (Cox proportional hazards models) were used to determine whether the hazard for developing hypertension (DBP>140, SBP>90) was greater in caregivers than in controls, and whether increased hazards were related to background characteristics or the extent of caregiving demands. Based on periodic 6-month assessments of BP over 6 years, the hazards of meeting criteria for borderline hypertension were greater for caregivers than for controls (Cox Proportional Hazards, chi2 [1, N = 174] = 4.86, p = 0.03). This difference remained statistically significant (p<0.05) after controlling for age, gender, education, socioeconomic status, body mass index, and use of antihypertensive medications. Increased risk of hypertension was not related to the extent of daily living assistance provided, patient problem behaviors, or caregiver distress. The chronic stress of caring for an AD spouse may have adverse effects on blood pressure; however, the mechanism for this relationship remains unclear.

A cross-cultural validation of coping strategies and their associations with caregiving distress.

Coping strategies were compared among family caregivers of Alzheimer's disease patients in Shanghai, China (n = 110) and San Diego, California (n = 139). Four coping factors were reliably consistent in both samples, supporting their widespread relevance to life adversity; behavioral confronting, behavioral distancing/social support, cognitive confronting, and cognitive distancing. Shanghai and San Diego caregivers endorsed similar rates of coping, but Shanghai caregivers reported fewer symptoms of depression and anxiety. Although coping strategies were similar, cultural ideals promoting family interdependence, veneration of elderly family members, and acceptance of traditional family roles may have reduced the psychological impacts of caregiving in the Shanghai sample.

Use of community support services by middle-aged and older patients with psychotic disorders.

OBJECTIVE: The study sought to determine the degree to which use of community services is related to predisposing, enabling, and need factors among older patients with psychotic disorders who live in the community and to assess whether high use of community services is associated with improving or declining psychopathology. METHODS: The sample consisted of 89 middle-aged and elderly community-dwelling patients with schizophrenia or other psychotic disorders. Assessments at baseline and two follow-ups at six-month intervals included measures of psychopathology, well-being, and social adjustment, in addition to the frequency of use of 17 formal community services in three categories-psychological, social, and daily living services. RESULTS: Ninety-two percent of patients reported use of community support services. The mean number of annual service contacts per patient was 36.6 for psychological services, 81 for social services, and 39.7 for daily living services. High users of psychological services were younger and experienced more severe positive psychotic symptoms and depressive symptoms. High users of social services were of higher socioeconomic status, more likely to be female, and had a longer history of psychosis, more cognitive deficits, and more severe negative psychotic and depressive symptoms. Patients who used daily living services were older, had poorer functional health status and more cognitive deficits, and had more severe negative psychotic and depressive symptoms. A trend was noted for high users of social services to experience relief from depressive symptoms over time. CONCLUSIONS: Use of community services is common among older outpatients with psychotic disorders, but its frequency varies as a function of patient characteristics.

Early prognosis for low back disability: intervention strategies for health care providers.

PURPOSE: Disability following acute occupational low back pain (OLBP) represents a significant and preventable health outcome, yet confusion about prognostic factors have limited the development of effective, targeted interventions for those at greatest risk. The purpose of this study was to synthesize findings from available studies of prognostic factors for OLBP disability in a clinically-relevant framework. METHOD: A systematic search of the MEDLINE database was conducted to identify empirical studies assessing the value of various prognostic factors to predict extended disability after an acute episode of OLBP. Relevant studies were screened based on a number of inclusionary criteria. Prognostic factors were catalogued, summarized, and evaluated based on agreement across studies, and clinical recommendations were developed based on the evidence. RESULTS: Of 361 studies of OLBP disability found, 22 met specific criteria for inclusion. Significant prognostic factors included low workplace support, personal stress, shorter job tenure, prior episodes, heavier occupations with no modified duty, delayed reporting, severity of pain and functional impact, radicular findings and extreme symptom report. Physicians can decrease OLBP disability by using standardized questionnaires, improving communication with patients and employers, specifying return to work accommodations, and employing behavioural approaches to pain and disability management. Future studies should evaluate interventions guided by prognosis.

Clinical tools to facilitate workplace accommodation after treatment for an upper extremity disorder.

Failure to implement work site accommodations for work-related upper extremity disorders (WRUEDs) may be a factor contributing to delayed functional recovery and relapse. The present study describes the use of the 38-item Job Requirements and Physical Demands (JRPD) scale, a self-report measure of ergonomic exposure, and other case management tools to improve accommodation efforts for 101 workers (75 women, 26 men) returning to work after lost time related to a WRUED. Items were categorized into five subscales based on item content: administrative, computer-related, workstation design, environmental, and equipment. Administrative risk factors were elevated among office clerks, whereas postal clerks and letter carriers reported more workstation design risk factors, and letter carriers and electrical/mechanical workers cited more equipment-related risk factors (p < 0.05). All occupational categories rated computer-related risk factors highest. The Integrated Case Management (ICM) approach, which relies on the JRPD scale to guide recommendations, was used with a subgroup of these workers (n = 53), resulting in 1.4 times more workplace accommodations per worker than with a non-ICM approach. Clinical use of the self-reported exposure measure within the overall workplace accommodation process may have been a factor contributing to more frequent accommodation in the ICM group. This study of a subgroup of workers' compensation cases highlights the need for additional investigation of tools to integrate ergonomic approaches within the workplace accommodation process.

Case management services for work related upper extremity disorders. Integrating workplace accommodation and problem solving.

A case manager's ability to obtain worksite accommodations and engage workers in active problem solving may improve health and return to work outcomes for clients with work related upper extremity disorders (WRUEDs). This study examines the feasibility of a 2 day training seminar to help nurse case managers identify ergonomic risk factors, provide accommodation, and conduct problem solving skills training with workers' compensation claimants recovering from WRUEDs. Eight procedural steps to this case management approach were identified, translated into a training workshop format, and conveyed to 65 randomly selected case managers. Results indicate moderate to high self ratings of confidence to perform ergonomic assessments (mean = 7.5 of 10) and to provide problem solving skills training (mean = 7.2 of 10) after the seminar. This training format was suitable to experienced case managers and generated a moderate to high level of confidence to use this case management approach.

When the wind goes out of the sail - declining recovery expectations in the first weeks of back pain.

BACKGROUND: Expectations for recovery are a known predictor for returning to work. Most studies seem to conclude that the higher the expectancy the better the outcome. However, the development of expectations over time is rarely researched and experimental studies show that realistic expectations rather than high expectancies are the most adaptive. This study aims to explore patterns of stability and change in expectations for recovery during the first weeks of a back-pain episode and how these patterns relate to other psychological variables and outcome. METHODS: The study included 496 volunteer patients seeking treatment for work-related, acute back pain. The participants were measured with self-report scales of depression, fear of pain, life impact of pain, catastrophizing and expectations for recovery at two time points. A follow-up focusing on recovery and return to work was conducted 3 months later. A cluster analysis was conducted, categorizing the data on the trajectories of recovery expectations. RESULTS: Cluster analysis revealed four clusters regarding the development of expectations for recovery during a 2-week period after pain onset. Three out of four clusters showed stability in their expectations as well as corresponding levels of proximal psychological factors. The fourth cluster showed increases in distress and a decrease in expectations for recovery. This cluster also has poor odds ratios for returning to work and recovery. CONCLUSION: Decreases in expectancies for recovery seem as important as baseline values in terms of outcome, which has clinical and theoretical implications.

Impact of organizational policies and practices on workplace injuries in a hospital setting.

OBJECTIVE: This study aimed to assess relationships between perceptions of organizational practices and policies (OPP), social support, and injury rates among workers in hospital units. METHODS: A total of 1230 hospital workers provided survey data on OPP, job flexibility, and social support. Demographic data and unit injury rates were collected from the hospitals' administrative databases. RESULTS: Injury rates were lower in units where workers reported higher OPP scores and high social support. These relationships were mainly observed among registered nurses. Registered nurses perceived coworker support and OPP as less satisfactory than patient care associates (PCAs). Nevertheless, because of the low number of PCAs at each unit, results for the PCAs are preliminary and should be further researched in future studies with larger sample sizes. CONCLUSIONS: Employers aiming to reduce injuries in hospitals could focus on good OPP and supportive work environment.

What is the prognosis of back pain?

Understanding prognosis is important in managing low back pain. In this article, we discuss the available evidence on low back pain prognosis and describe how prognostic evidence can be used to inform clinical decision making. We describe three main types of related prognosis questions: 'What is the most likely course?' (Course studies); 'What factors are associated with, or determine, outcome?' (Prognostic factor or explanatory studies); and 'Can we identify risk groups who are likely to have different outcomes?' (Risk group or outcome prediction studies). Most low back pain episodes are mild and rarely disabling, with only a small proportion of individuals seeking care. Among those presenting for care, there is variability in outcome according to patient characteristics. Most new episodes recover within a few weeks. However, recurrences are common and individuals with chronic, long-standing low back pain tend to show a more persistent course. Studies of mixed primary care populations indicate 60-80% of health-care consulters will continue to have pain after a year. Important low back pain prognostic factors are related to the back pain episode, the individual and psychological characteristics, as well as the work and social environment. Although numerous studies have developed prediction models in the field, most models/tools explain less than 50% of outcome variability and few have been tested in independent samples. We discuss limitations and future directions for research in the area of low back pain prognosis.

Disability management training for supervisors: a pilot intervention program.

Proactive disability management practices among employers have been associated with reduced frequency and duration of disability. Supervisors have a critical role in disability prevention. However, few studies have evaluated training efforts to modify supervisor responses in order to improve disability outcomes. In this study, 108 supervisors representing seven employers were provided a 1.5-h training session to reinforce a proactive and supportive response to work-related musculoskeletal symptoms and injuries among employees. Pre- and post training results showed improvements in supervisor confidence to investigate and modify job factors contributing to injury, to get medical advice, and to answer employees' questions related to injury and treatment (p < .05). More supervisors reported decreases (38.5%) than increases (9.6%) in lost work time within their departments. These data provide evidence that this approach may improve disability outcomes of work-related musculoskeletal disorders. Controlled trials with disability outcome data are needed to confirm these results.

The social networks of older schizophrenia patients. Clinical Research Center on Late Life Psychosis Research Group.

There is a paucity of research that examines the role of family members and friends in the lives of older schizophrenia patients. This study compared 66 middle-aged and elderly outpatients with 31 normal comparison subjects. Five dimensions of social network were assessed: (a) family composition, geographic proximity, and frequency of contact; (b) instrumental support; (c) emotional support and interpersonal difficulties; (d) role of friends; and (e) use of formal service providers as sources of support and assistance. As compared with normal subjects, the schizophrenia patients were less likely to be married, less likely to have children, more likely to live alone, and had fewer friendships. The patients were, however, similar to comparison subjects on the following family-relationship variables: frequency of contact, instrumental support received, presence of a family confidant, and extent of interpersonal difficulties. These findings do not support the stereotype of older schizophrenia patients as being estranged from family members. The need for developing interventions that use key family members to interface with service providers and to monitor treatment compliance and continuity of care is discussed.

Self-perceived interpersonal competence in older schizophrenia patients: the role of patient characteristics and psychosocial factors.

OBJECTIVE: This study compared older schizophrenia patients with normal subjects in terms of their perceived interpersonal competence. METHOD: A total of 95 middle-aged and elderly schizophrenia patients and 85 age-matched normal subjects completed the Interpersonal Competence Questionnaire. RESULTS: Patients scored significantly lower than normal subjects on initiation, provision of emotional support, and conflict management. Severity of psychiatric symptoms and other patient characteristics were examined as predictors of interpersonal competence among patients. Negative symptoms were inversely related to interpersonal competence, whereas emotional support from others and a positive appraisal coping style both yielded positive associations. CONCLUSION: These findings suggest the need for clinical interventions designed to enhance the interpersonal skills of older schizophrenia patients, particularly those with marked negative symptoms.
