Impacts of State-Level Opioid Review Programs on Injured Workers and Their Health Care Providers: A Qualitative Study in Washington and Ohio.

Policy Points Workers' compensation agencies have instituted opioid review policies to reduce unsafe prescribing. Providers reported more limited and cautious prescribing than in the past; both patients and providers reported collaborative pain-management relationships and satisfactory pain control for patients. Despite the fears articulated by pharmaceutical companies and patient advocates, opioid review programs have not generally resulted in unmanaged pain or reduced function in patients, anger or resistance from patients or providers, or damage to patient-provider relationships or clinical autonomy. Other insurance providers with broad physician networks may want to consider similar quality-improvement efforts to support safe opioid prescribing. CONTEXT: Unsafe prescribing practices have been among the central causes of improper reception of opioids, unsafe use, and overdose in the United States. Workers' compensation agencies in Washington and Ohio have implemented opioid review programs (ORPs)-a form of quality improvement based on utilization review-to curb unsafe prescribing. Evidence suggests that such regulations indeed reduce unsafe prescribing, but pharmaceutical companies and patient advocates have raised concerns about negative impacts that could also result. This study explores whether three core sets of problems have actually come to pass: (1) unmanaged pain or reduced function among patients, (2) anger or resistance to ORPs from patients or providers, and (3) damage to patient-provider relationships or clinical autonomy. METHODS: In-depth semistructured interviews were conducted with 48 patients (21 from Washington, 27 from Ohio) and 32 providers (18 from Washington, 14 from Ohio) who were purposively sampled to represent a range of injury and practice types. Thematic coding was conducted with codebooks developed using both inductive and deductive approaches. FINDINGS: The consequences of opioid regulations have been generally positive: providers report more limited prescribing and a focus on multimodal pain control; patients report satisfactory pain control and recovery alongside collaborative relationships with providers. Participants attribute these patterns to a broad environment of opioid caution; they do not generally perceive workers' compensation policies as distinctly impactful. Both patients and providers comment frequently on the difficult aspects of interacting with workers' compensation agencies; effects of these range from simple inconvenience to delays in care, unmanaged pain, and reduced potential for physical recovery. CONCLUSIONS: In general, the three types of feared negative impacts have not come to pass for either patients or providers. Although interacting with workers' compensation agencies involves difficulties typical of interacting with other insurers, opioid controls seem to have generally positive effects and are generally perceived of favorably.

Workplace Wellness Program Interest and Barriers Among Workers With Work-Related Permanent Impairments.

BACKGROUND: Nearly half of U.S. workers have access to workplace wellness programs (WWPs), 58% of workers with access participate. The aim of this study was to assess interest in WWP participation and identify reasons for lack of interest among workers with work-related permanent impairments-a population at elevated risk of adverse health outcomes. METHODS: Workers who returned to work after a work-related permanent impairment were interviewed 11 to 15 months after workers' compensation claim closure. Qualitative content analysis methods were used to code open-ended responses. FINDINGS: Of 560 respondents, 51.4% expressed interest in WWP participation. Numerous adverse health and economic characteristics were associated with WWP interest, for example, interest was expressed by 63.3% of workers reporting fair/poor health status versus 47.1% reporting good/excellent; 56.9% of workers reporting moderate/severe pain versus 41.4% reporting mild/no pain; 64.7% of workers without health insurance versus 50.1% with health insurance; 69.0% of workers reporting depression versus 47.2% without depression; 70.4% of workers reporting obesity versus 48.0% without obesity; and 63.2% of workers often worried about expenses versus 46.9% reporting sometimes/never worried. Specific participation barriers were described by 34.2% of the 272 workers who were not interested. CONCLUSIONS/APPLICATIONS TO PRACTICE: A majority of workers with work-related permanent impairments-particularly those with adverse health and economic characteristics-were interested in WWPs. Many workers who reported no interest cited participation barriers. Further research is needed to determine whether addressing such barriers would enhance equitable access. Those undertaking WWP planning, implementation, and outreach should ensure that WWPs are inclusive and serve workers with disabilities.

Workplace Organizational and Psychosocial Factors Associated with Return-to-Work Interruption and Reinjury Among Workers with Permanent Impairment.

OBJECTIVES: Roughly 10% of occupational injuries result in permanent impairment and a permanent partial disability (PPD) award. After initial return to work (RTW) following a work injury, many workers with permanent impairment face RTW interruption (breaks in ongoing employment due to reinjury, poor health, disability, lay-off, etc.). Most RTW and reinjury research has focused on worker-level risk factors, and less is known about contextual factors that may be amenable to workplace or workers' compensation (WC)-based interventions. The aim of this study was to identify modifiable organizational and psychosocial workplace factors associated with (i) RTW interruption and (ii) reinjury among workers with a permanent impairment. METHODS: This retrospective cohort study included WC claims data and survey data for 567 injured workers who RTW at least briefly after a work-related injury that resulted in permanent impairment. Workers were interviewed once by phone, 11-15 months after WC claim closure with a PPD award. Logistic regression models were used to estimate associations between each workplace factor of interest and each outcome, controlling for whole body impairment percentage, gender, age, nativity, educational level, State Fund versus self-insured WC coverage, employer size, union membership, industry sector, and employment duration of current/most recent job. RESULTS: Twelve percent of workers had been reinjured in their current or most recent job, 12% of workers were no longer working at the time of interview, and <1% of workers reported both outcomes. The most frequently reported reason for RTW interruption was impairment, disability, and/or pain from the previous work injury. Lower reported levels of safety climate, supervisor support, and ability to take time off work for personal/family matters were significantly associated with both RTW interruption and reinjury. Inadequate employer/health care provider communication, perceived stigmatization from supervisors and/or coworkers, and lower levels of coworker support were significantly associated with RTW interruption but not with reinjury. Discomfort with reporting an unsafe situation at work, absence of a health and safety committee, and higher job strain were significantly associated with reinjury, but not with RTW interruption. Inadequate safety training and lack of needed job accommodations were not significantly associated with either outcome. There were no notable or statistically significant interactions between workplace factors and degree of impairment, and no consistent direction of association. CONCLUSIONS: This study provides evidence that several potentially modifiable organizational and psychosocial factors are associated with safe and sustained RTW among injured workers with work-related permanent impairment. The lack of interaction between any of these workplace factors and degree of impairment suggests that these findings may be generalizable to all workers, and further suggests that workplace interventions based on these findings might be useful for both primary and secondary prevention. Though primary prevention is key, secondary prevention efforts to sustain RTW and prevent reinjury may reduce the considerable health, economic, and social burden of occupational injury and illness.

Estimating time to reinjury among Washington State injured workers by degree of permanent impairment: Using state wage data to adjust for time at risk.

BACKGROUND: Many injured workers are reinjured, but reinjury risk is challenging to quantify. Because many injured workers face delayed return-to-work, or return to part-time or intermittent jobs, a calendar timescale may overestimate actual work-time at risk, yielding underestimated reinjury rates. Objectives included determining: (1) reinjury risk by degree of permanent impairment and other factors, and (2) how choice of timescale affects reinjury estimates. METHODS: This retrospective cohort study included Washington State workers' compensation (WC) claims for 43,114 injured workers, linked to state wage files (2003-2018). Three timescales were used to define at-risk denominators: (1) calendar quarters; (2) quarters with any wages; and (3) full-time equivalent (FTE) quarters, defined as cumulative work hours ÷ 520. Associations between reinjury outcomes and worker, injury, job, and WC vocational rehabilitation program participation characteristics were assessed using Cox proportional hazards regression. RESULTS: Overall reinjury rates were 5.9 per 100 worker-years using a calendar timescale (95% confidence interval [CI]: 5.8-6.0), 10.0 using any-wage quarters (95% CI: 9.9-10.2), and 12.5 using FTE quarters (95% CI: 12.3-12.7). Reinjury rates were highest in the first two quarters after initial injury, remaining elevated for about 4 years. Using FTE quarters, workers with ≥10% whole body impairment had a 34% higher risk of reinjury relative to workers with no permanent partial disability award (95% CI: 1.25-1.44); no difference was detected using calendar time. CONCLUSIONS: Timescale substantially affects reinjury estimates and comparisons between groups with differential return-to-work patterns. Linking wage data to WC claims facilitates measurement of long-term employment, yielding more accurate reinjury estimates.

Workforce Reintegration After Work-Related Permanent Impairment: A Look at the First Year After Workers' Compensation Claim Closure.

Purpose The purpose of this study was to descriptively quantify experiences of injured workers with permanent impairment during their first year of work reintegration. Methods A representative survey was conducted to characterize health, disability, pain, employment, reinjury, and economic outcomes for 598 workers with permanent impairment who had returned to work during the year after workers' compensation claim closure. Survey responses were summarized by degree of whole body impairment (< 10% vs. ≥ 10%). Results Injured workers who had returned to work reported that permanent impairment made it difficult to get a job (47%) and to keep their job (58%). A year after claim closure, 66% reported moderate to very severe pain; 40% reported pain interference with work. About 13% reported new work injuries; over half thought permanent impairment increased their reinjury risk. Asked to compare current to pre-injury work status, workers with a higher degree of impairment more frequently reported working fewer hours (OR 1.60; 95% CI 1.06, 2.42), earning less (OR 1.56; 95% CI 1.04, 2.36), and being at higher risk of losing their current job due to their impairment (OR 1.66; 95% CI 1.01, 2.71). Conclusions Injured workers with permanent impairment face long-term challenges related to health limitations, chronic pain, work reintegration, and economic impacts. Workers with a higher degree of impairment more frequently reported several economic and job security challenges. Developing workplace and workers' compensation-based interventions that reduce return-to-work interruption and reinjury for workers with permanent impairment should be prioritized as an important public health and societal goal.

Opioid Overdose Hospitalization Trajectories in States With and Without Opioid-Dosing Guidelines.

OBJECTIVES: High-risk opioid-prescribing practices contribute to a national epidemic of opioid-related morbidity and mortality. The objective of this study was to determine whether the adoption of state-level opioid-prescribing guidelines that specify a high-dose threshold is associated with trends in rates of opioid overdose hospitalizations, for prescription opioids, for heroin, and for all opioids. METHODS: We identified 3 guideline states (Colorado, Utah, Washington) and 5 comparator states (Arizona, California, Michigan, New Jersey, South Carolina). We used state-level opioid overdose hospitalization data from 2001-2014 for these 8 states. Data were based on the State Inpatient Databases and provided by the Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality, via HCUPnet. We used negative binomial panel regression to model trends in annual rates of opioid overdose hospitalizations. We used a multiple-baseline difference-in-differences study design to compare postguideline trends with concurrent trends for comparator states. RESULTS: For each guideline state, postguideline trends in rates of prescription opioid and all opioid overdose hospitalizations decreased compared with trends in the comparator states. The mean annual relative percentage decrease ranged from 3.2%-7.5% for trends in rates of prescription opioid overdose hospitalizations and from 5.4%-8.5% for trends in rates of all opioid overdose hospitalizations. CONCLUSIONS: These findings provide preliminary evidence that opioid-dosing guidelines may be an effective strategy for combating this public health crisis. Further research is needed to identify the individual effects of opioid-related interventions that occurred during the study period.

Expanding vocational retraining options for injured workers: An experiment in worker choice.

BACKGROUND: An innovative self-directed vocational retraining alternative (Option 2) has been offered to eligible Washington State injured workers since 2008. OBJECTIVE: We aimed to describe: (1) how frequently Option 2 was selected and by whom, (2) the extent to which Option 2 workers used their reserved retraining funds, and (3) how worker satisfaction and employment outcomes for Option 2 workers compared with those of workers undergoing traditional vocational retraining. METHODS: Five-year cohort study involving workers' compensation data, state wage files, and two worker surveys. RESULTS: Fewer than 25% of Option 2 workers used their retraining funds. Retraining fund use was associated with better employment outcomes. Workers who were older, whose preferred language was not English, or who had lower pre-injury wages or less education, were least likely to use Option 2 retraining funds. Many workers chose Option 2 because they thought the approved traditional retraining plan was not a good fit for them. CONCLUSIONS: Self-directed retraining may benefit workers who have the ability, resources, and motivation to independently identify and complete retraining. Additional efforts may be needed to ensure that traditional retraining plans are well-suited to workers' circumstances, and to identify and remove barriers to use of reserved retraining funds.

Vocational rehabilitation program evaluation: comparison group challenges and the role of unmeasured return-to-work expectations.

PURPOSE: Despite the importance and cost of workers' compensation (WC)-based vocational rehabilitation (VR) programs, outcome evaluations are rare, in part due to the scarcity of suitable comparison groups. The aims of this study were to assess (1) the adequacy of a commonly recommended internal comparison group, i.e., workers who were eligible for but did not receive services, and (2) return-to-work (RTW) expectations as a potential source of bias. METHODS: In this prospective cohort study, we used WC claims data and worker-reported RTW expectations to compare workers who received vocational retraining services to eligible workers who did not receive such services. Workers were surveyed after retraining eligibility determination, prior to the initiation of retraining activities. VR progress and RTW wage outcomes were followed for 3 years. The magnitude of confounding contributed by RTW expectations and other covariates was quantified. RESULTS: Workers who were somewhat or very certain they would RTW had significantly better outcomes. RTW expectations played a strong confounding role, reducing the retraining plan effect estimate by about 23 %, while education and physical capacity each changed the effect estimate by <5 %. CONCLUSIONS: RTW expectations predicted long-term RTW outcomes and can play a strong confounding role if unmeasured. We found that the internal comparison group approach, commonly recommended for VR program evaluation, is inappropriate for WC-based VR evaluations. Ultimately, there is no simple solution to the challenge of identifying a comparison group; however, measurement of RTW expectations, an easily-measured multi-dimensional construct, may be a useful addition to the VR evaluation toolbox.

Improving vocational rehabilitation services for injured workers in Washington State.

Workers who incur permanent impairments or have ongoing medical restrictions due to injuries or illnesses sustained at work may require support from vocational rehabilitation programs in order to return to work. Vocational rehabilitation programs implemented within workers' compensation settings are costly, and effective service delivery has proven challenging. The Vocational Improvement Project, a 5.5-year pilot program beginning in 2008, introduced major changes to the Washington State workers' compensation-based vocational rehabilitation program. In the evaluation of this pilot program, set within a large complex system characterized by competing stakeholder interests, we assessed effects on system efficiency and employment outcomes for injured workers. While descriptive in nature, this evaluation provided evidence that several of the intended outcomes were attained, including: (1) fewer repeat referrals, (2) fewer delays, (3) increased choice for workers, and (4) establishment of statewide partnerships to improve worker outcomes. There remains substantial room for further improvement. Retraining plan completion rates remain under 60% and only half of workers earned any wages within two years of completing their retraining plan. Ongoing communication with stakeholders was critical to the successful conduct and policy impact of this evaluation, which culminated in a 3-year extension of the pilot program through June 2016.

Injured workers' assessment of vocational rehabilitation services before and after retraining.

PURPOSE: Workers' compensation-based vocational rehabilitation (VR) programs are costly and challenging to operate effectively. This study aimed to: (1) describe injured workers' assessment of Washington State's VR system before and after vocational retraining, (2) describe the factors affecting injured worker satisfaction with VR services, and (3) gather suggestions for program improvement from injured workers. METHODS: Telephone surveys were conducted in two distinct samples: (1) 361 workers were interviewed after determination of retraining eligibility but before retraining plan development, and (2) 360 workers were interviewed after cessation of vocational services and claim closure. RESULTS: Injured workers interviewed before retraining were more often satisfied with the VR system (69 %) than were those interviewed after VR services ended (46 %). Although 55 % were initially somewhat/very certain they would return to work (RTW) after retraining, only 21 % had RTW 3-6 months after claim closure. Poor health, poor functional ability, and multiple retraining attempts were significantly associated with dissatisfaction. Suggestions for program improvement fell most frequently into the following areas: (1) more training choices, more worker input into the retraining goal, and/or a better fit of the retraining goal with the workers' experience and abilities (25 %); (2) listen to, respect, and/or understand the worker with regard to their interests, goals, and limitations (17 %); and (3) more support with job placement, work re-entry skills, and RTW in general (9 %). CONCLUSIONS: There is substantial room for improvement in worker satisfaction with VR. Injured workers' feedback may facilitate identification of opportunities to improve the VR process and RTW outcomes.

Opioid use disorder in the United States: insurance status and treatment access.

BACKGROUND: In the United States, insurance status and rates of treatment for individuals with opioid use disorder are unknown. METHODS: Cross-sectional survey: 2002-2004 National Survey on Drug Use and Health (NSDUH). Bivariate and multivariate associations between demographics, treatment and insurance status and presence or absence of opioid use disorder were investigated. RESULTS: On unadjusted analysis, young respondents, respondents of Hispanic ethnicity (OR 1.5; 95% CI 1.1-2.2), unemployed respondents (OR 2.6; 95% CI 1.8-3.8) and respondents with Medicaid (OR 4.5; 95% CI 2.5-8.3) or lack of insurance (OR 3.2; 95% CI 1.8-5.9) were more likely to have opioid use disorder. On unadjusted analysis among those with any substance use disorder, 12-16 year olds were more likely to have opioid use disorder (OR 3.4; 95% CI 2.0-5.8) than a non-opioid substance use disorder, as were women (OR for men 0.6; 95% CI 0.5-0.7) and unemployed respondents (OR 1.5; 95% CI 1.02-2.1). Only 15.2% of those with past-year opioid use disorder received treatment in the past year. Respondents treated for opioid use had higher rates of Medicaid (p<0.01), Medicare (p<0.01) and other public assistance (p=0.01) compared with those treated for other substances. Treatments for opioid use were more likely to be hospital (p=0.04) and inpatient rehabilitation (p=0.02) settings compared to treatment for other substance use. Among those with opioid use disorder, not being employed was independently associated with receiving treatment (AOR 3.5; 95% CI 1.4-8.5). CONCLUSIONS: In the U.S., high rates of unemployment, Medicaid and uninsurance among those with opioid use disorder and low rates of treatment suggest that efforts to expand treatment must include policy strategies to help reach a population with significant barriers to treatment access.

Methadone medical maintenance in primary care. An implementation evaluation.

BACKGROUND: Methadone is effective treatment for opioid addiction, but regulations restrict its use. Methadone medical maintenance treats stabilized methadone patients in a medical setting, but only experimental programs have been studied. OBJECTIVE: To evaluate the implementation of the first methadone medical maintenance program established outside a research setting. DESIGN: One-year program evaluation. SETTING: A public hospital and a community opioid treatment program. PARTICIPANTS: Methadone patients with >1 year of clinical stability. Eleven generalist physicians and 4 hospital pharmacists. INTERVENTIONS: Regulatory exemptions were requested. Physicians and pharmacists were trained. Patients were transferred to the medical setting and permitted 1-month supplies of methadone. MEASUREMENTS: Patient eligibility and willingness to enroll, treatment retention, urine toxicology results, change in addiction severity and functional status, medical services provided, patient and physician satisfaction, and physician attitudes toward methadone maintenance. RESULTS: Regulatory exemptions were obtained after a 14-month process, and the program was cited in federal policy as acceptable for widespread implementation. Forty-nine of 684 patients (7.2%) met stability criteria, and 30 enrolled. Twenty-eight were retained for 1 year, and 2 transferred to other programs. Two patients had opioid-positive urine tests and were managed in the medical setting. Previously unmet medical needs were addressed, and the Addiction Severity Index (ASI) medical composite score improved over time (P=.02). Patient and physician satisfaction were high, and physician attitudes toward methadone maintenance treatment became more positive (P=.007). CONCLUSIONS: Methadone medical maintenance is complex to arrange but feasible outside a research setting, and can result in good clinical outcomes.

Childhood immunization registries: gaps between knowledge and action among family practice physicians and pediatricians in Washington state, 1998.

OBJECTIVES: To assess the availability and use of Washington State's CHILD (Children's Health, Immunization, Linkages, and Development) Profile and other computerized immunization tracking systems, to determine physicians' attitudes about these systems, and to identify factors associated with using them. DESIGN: Randomized, population-based, cross-sectional survey. PARTICIPANTS: Washington family physician and pediatrician specialty organization members providing childhood immunizations in 1998 (N = 2472). MAIN OUTCOME MEASURE: Reported CHILD Profile and other computerized systems use. RESULTS: The adjusted response rate was 75% (n = 1331). Overall, 37.7% of respondents had heard of CHILD Profile, 6.3% used it, and 24.9% used other systems. Groups significantly more likely not to use computerized systems than referent pediatricians in areas fully implementing CHILD Profile were family physicians (adjusted odds ratio [aOR], 2.4; 95% confidence interval [CI], 1.4-4.0), private physicians (aOR, 8.0; 95% CI, 3.2-20.1), physicians taking fewest opportunities to immunize (aOR, 2.3; 95% CI, 1.4-3.7), and physicians practicing in local health jurisdiction areas with CHILD Profile marketing activity (aOR, 2.1; 95% CI, 1.2-3.9) or in those areas with little or no registry activity (aOR, 2.6; 95% CI, 1.6-4.4). Those with systems agreed that they save time (71.0%), make status checks easier (87.1%), and increase immunization coverage (88.6%). Those without systems agreed that they help practices (90.3%) and increase efficiency (76.5%), but fewer agreed that they reduce costs (30.2%). CONCLUSIONS: Although most physicians agreed that computerized systems are useful, few had them or used them. Provider-based systems can improve immunization coverage, but the feasibility and effectiveness of communitywide and statewide systems remain unexplored. Because these systems depend on participation, more understanding is needed to help organizations implement them. Interventions to increase availability and use should address provider and health organization needs.
