Physical activity with person-centered guidance supported by a digital platform or with telephone follow-up for persons with chronic widespread pain: Health economic considerations along a randomized controlled trial.

OBJECTIVES: The aim was to investigate the resource use and costs associated with the co-creation of a physical activity plan for persons with chronic widespread pain (CWP) followed by support through a digital platform, compared to telephone follow-up. METHODS: In this 12-month cost comparison study following up results after a randomized controlled trial, individuals with CWP, aged 20-65 years, were recruited at primary healthcare units in Western Sweden. All participants developed a person-centered health-enhancing physical activity plan together with a physiotherapist. Participants were then randomized to either an intervention group (n = 69) who had a follow-up visit after 2 weeks and was thereafter supported through a digital platform, or an active control group (n = 70) that was followed up through one phone call after a month. Costs to the health system were salary costs for the time recorded by physiotherapists when delivering the interventions. RESULTS: The reported time per person (2.8 h during the 12 months) corresponded to costs of SEK 958 (range: 746-1,517) for the initial visits and follow-up (both study groups), and an additional 2.5 h (corresponding to a mean SEK 833; range: 636-1,257) for the time spent in the digital platform to support the intervention group. CONCLUSION: After co-creation of a physical activity plan, it was more costly to support persons through a digital platform, compared to telephone follow-up.

Patients' willingness to pay for naloxone: A national cross-sectional survey of prescription opioid users with chronic pain in the United States.

BACKGROUND: Millions of U.S. people have been heavily affected by opioids. In March 2023, the Food and Drug Administration approved naloxone as an over-the-counter medication. This has allowed more access to patients at high risk of opioid overdose. However, the patient's willingness to pay for naloxone at the pharmacy counter has not been assessed. OBJECTIVES: This study aimed to characterize factors associated with the willingness to pay for naloxone among the patient group. METHODS: A cross-sectional Qualtrics online panel survey instrument was developed. This survey was distributed to patients in the United States, aged ≥ 18 years, with any chronic pain and taking opioids. The survey included demographics, and clinical characteristics (pain assessment, opioid use, and knowledge of naloxone). In addition, willingness to pay was assessed using a 7-point Likert scale ranging from strongly disagree to strongly agree. An ordinal logistic regression model was used to examine demographic and clinical characteristics. RESULTS: A total of 549 subjects completed the survey (women [53.01%], white or Caucasian (83.61%), age mean [SD] 44 [13]). Women were associated with less willingness to pay (adjusted odds ratio [aOR] 0.685 [95% CI 0.478-0.983], P = 0.0403). Compared with the high household income group (≥ $150,000), low household income ≤ $25,000 (aOR 0.326 [95% CI 0.160-0.662], P = 0.0020) or income between $25,000 and 74,999 (aOR 0.369 [95% CI 0.207-0.657], P = 0.0007) was associated with less likelihood of willing to pay. Patients with a previous diagnosis of obstructive sleep apnea were associated with a higher likelihood of willingness to pay (aOR 1.685 [95% CI 1.138-2.496], P = 0.0092). Each unit increase in pain was also associated with a higher likelihood of willingness to pay (aOR 1.247 [95% CI 1.139-1.365], P < 0.0001). CONCLUSIONS: Demographics and clinical factors were associated with willingness to pay for naloxone. This study's findings are useful in the development of interventions to address pharmacy-based naloxone distribution programs.

Predictors of Sickness Absence in a Clinical Population With Chronic Pain.

Chronic pain-related sickness absence is an enormous socioeconomic burden globally. Optimized interventions are reliant on a lucid understanding of the distribution of social insurance benefits and their predictors. This register-based observational study analyzed data for a 7-year period from a population-representative sample of 44,241 chronic pain patients eligible for interdisciplinary treatment (IDT) at specialist clinics. Sequence analysis was used to describe the sickness absence over the complete period and to separate the patients into subgroups based on their social insurance benefits over the final 2 years. The predictive performance of features from various domains was then explored with machine learning-based modeling in a nested cross-validation procedure. Our results showed that patients on sickness absence increased from 17% 5 years before to 48% at the time of the IDT assessment, and then decreased to 38% at the end of follow-up. Patients were divided into 3 classes characterized by low sickness absence, sick leave, and disability pension, with eight predictors of class membership being identified. Sickness absence history was the strongest predictor of future sickness absence, while other predictors included a 2008 policy, age, confidence in recovery, and geographical location. Information on these features could guide personalized intervention in the specialized healthcare. PERSPECTIVE: This study describes sickness absence in patients who visited a Swedish pain specialist interdisciplinary treatment clinic during the period 2005 to 2016. Predictors of future sickness absence are also identified that should be considered when adapting IDT programs to the patient's needs.

The effect of continuity of care on medical costs in patients with chronic shoulder pain.

Unnecessary surgery could be prevented through continuity of care (COC). The present study aimed to investigate the relationships between COC, surgery and cost associated with chronic shoulder pain. We used the Health Insurance Review and Assessment Service national patient sample (HIRA-NPS) in 2017. A total of 1717 patients were included. Bice-Boxerman Continuity of Care Index was used as the indicator for measuring the COC. Occurrence of surgery, associated costs, and direct medical costs were analysed. Logistic regression, a two-part model with recycled predictions and generalized linear model with gamma distribution were used. The majority of patients were 40-65 years old (high COC: 68.4%; low COC: 64.4%). The odds ratio (OR) for surgery was 0.41 in the high-COC group compared to the low COC group (95% CI, 0.20 to 0.84). Direct medical cost was 14.09% (95% CI, 8.12% to 19.66%) and 58.00% lower in surgery cost (95% CI, 57.95 to 58.05) in the high-COC group. Interaction with COC and shoulder impingement syndrome was significant lower in direct medical cost (15.05% [95% CI, 1.81% to 26.51%]). High COC was associated with low medical cost in patients diagnosed with chronic shoulder pain.

The contemporary management of neck pain in adults.

Neck pain is a common condition with a high prevalence worldwide. Neck pain is associated with significant levels of disability and is widely considered an important public health problem. Neck pain is defined as pain perceived between the superior nuchal line and the spinous process of the first thoracic vertebra. In some types of neck conditions, the pain can be referred to the head, trunk and upper limbs. This article aims to provide an overview of the available evidence on prevalence, costs, diagnosis, prognosis, risk factors, prevention and management of patients with neck pain.

A Cost-effectiveness Analysis of an Internet-delivered Pain Management Program Delivered With Different Levels of Clinician Support: Results From a Randomised Controlled Trial.

There is growing interest in the potential of internet-delivered pain management programs (PMPs) to increase access to care for people with chronic pain. However, very few economic evaluations of these interventions have been reported. Using existing data, the current study examined the cost-effectiveness of an internet-delivered PMP for a mixed group chronic pain patients (n = 490) provided with different levels of clinician support. The findings indicated that each additional clinical outcome (defined as a ≥ 30% reduction in disability, depression, anxiety, and pain) was associated with cost-savings when the intervention was provided in a self-guided format (ICER range: -$404--$808 AUD) or an optional-guided format (ICER range: -$314--$541 AUD), and a relatively small fixed cost when provided in the clinician-guided format (ICER range: $88-$225 AUD). The results were driven by a reduction in service use costs among the treatment groups, which offset the costs of providing the internet-delivered PMP in the self-guided and optional-guided formats. The same general pattern of results was found when more stringent clinical outcomes (defined as a ≥ 50% reduction) were employed. These findings suggest that carefully developed and administered internet-delivered PMPs, provided with different levels of clinician support, can be highly cost effective for patients with a broad range of pain conditions. PERSPECTIVE: This study examines the cost-effectiveness of an internet-delivered PMP provided to adults with a broad range of chronic pain conditions. Evidence of cost-effectiveness was found across a broad range of clinical outcomes and with different levels of clinician support.

The (cost-)effectiveness and cost-utility of a novel integrative care initiative for patients with chronic musculoskeletal pain: the pragmatic trial protocol of Network Pain Rehabilitation Limburg.

BACKGROUND: Rehabilitation care for patients with chronic musculoskeletal pain (CMP) is not optimally organized. The Network Pain Rehabilitation Limburg 2.0 (NPRL2.0) provides integrated care with a biopsychosocial approach and strives to improve the Quadruple Aim outcomes: pain-related disability of patients with CMP; experiences of care of patients with CMP; meaning in the work of healthcare professionals; and healthcare costs. Firstly, in this study, the effectiveness (with regard to the functioning and participation of patients) of primary care for patients with CMP will be assessed, comparing care organized following the NPRL2.0 procedure with usual care. Secondly, the cost-effectiveness and cost-utility with regard to health-related quality of life and healthcare costs will be assessed. And thirdly, the effect of duration of participation in a local network in primary care will be studied. METHODS: In this pragmatic study, it is expected that two local networks with 105 patients will participate in the prospective cohort study and six local networks with 184 patients in the stepped-wedge based design. Healthcare professionals in the local networks will recruit patients. INCLUSION CRITERIA: age ≥ 18 years; having CMP; willing to improve functioning despite pain; and adequate Dutch literacy. EXCLUSION CRITERIA: pregnancy; and having a treatable medical or psychiatric disease. Patients will complete questionnaires at baseline (T1), 3 months (T2), 6 months (T3), and 9 months (T4). Questionnaires at T1 and T4 will include the Pain Disability Index and Short Form Health Survey. Questionnaires at T1, T2, T3, and T4 will include the EQ-5D-5L, and iMTA Medical Consumption and Productivity Cost Questionnaires. Outcomes will be compared using linear mixed-model analysis and costs will be compared using bootstrapping methods. DISCUSSION: NPRL2.0 is a multidimensional, complex intervention, executed in daily practice, and therefore needing a pragmatic study design. The current study will assess NPRL2.0 with respect to the Quadruple Aim outcomes: patient health and costs. This will provide more information on the (cost-) effectiveness of the organization of care in a network structure regarding patients with CMP. The other two Quadruple Aim outcomes will be examined alongside this study. Trial registration Netherlands Trial Register: NL7643. https://www.trialregister.nl/trial/7643 .

Critical NIH Resources to Advance Therapies for Pain: Preclinical Screening Program and Phase II Human Clinical Trial Network.

Opioid-related death and overdose have now reached epidemic proportions. In response to this public health crisis, the National Institutes of Health (NIH) launched the Helping to End Addiction Long-term InitiativeSM, or NIH HEAL InitiativeSM, an aggressive, trans-agency effort to speed scientific solutions to stem the national opioid public health crisis. Herein, we describe two NIH HEAL Initiative programs to accelerate development of non-opioid, non-addictive pain treatments: The Preclinical Screening Platform for Pain (PSPP) and Early Phase Pain Investigation Clinical Network (EPPIC-Net). These resources are provided at no cost to investigators, whether in academia or industry and whether within the USA or internationally. Both programs consider small molecules, biologics, devices, and natural products for acute and chronic pain, including repurposed and combination drugs. Importantly, confidentiality and intellectual property are protected. The PSPP provides a rigorous platform to identify and profile non-opioid, non-addictive therapeutics for pain. Accepted assets are evaluated in in vitro functional assays to rule out opioid receptor activity and to assess abuse liability. In vivo pharmacokinetic studies measure plasma and brain exposure to guide the dose range and pretreatment times for the side effect profile, efficacy, and abuse liability. Studies are conducted in accordance with published rigor criteria. EPPIC-Net provides academic and industry investigators with expert infrastructure for phase II testing of pain therapeutics across populations and the lifespan. For assets accepted after a rigorous, objective scientific review process, EPPIC-Net provides clinical trial design, management, implementation, and analysis.

Update of Markov Model on the Cost-effectiveness of Nonpharmacologic Interventions for Chronic Low Back Pain Compared to Usual Care.

STUDY DESIGN: Markov model. OBJECTIVE: Further validity test of a previously published model. SUMMARY OF BACKGROUND DATA: The previous model was built using data from ten randomized trials and examined the 1-year effectiveness and cost-effectiveness of 17 nonpharmacologic interventions for chronic low back pain (CLBP), each compared to usual care alone. This update incorporated data from five additional trials. METHODS: Based on transition probabilities that were estimated using patient-level trial data, a hypothetical cohort of CLBP patients transitioned over time among four defined health states: high-impact chronic pain with substantial activity limitations; higher (moderate-impact) and lower (low-impact) pain without activity limitations; and no pain. As patients transitioned among health states, they accumulated quality-adjusted life-years, as well as healthcare and productivity costs. Costs and effects were calculated incremental to each study's version of usual care. RESULTS: From the societal perspective and assuming a typical patient mix (25% low-impact, 35% moderate-impact, and 40% high-impact chronic pain), most interventions-including those newly added-were cost-effective (<$50,000/QALY) and demonstrated cost savings. From the payer perspective, fewer were cost-saving, but the same number were cost-effective. Results for the new studies generally mirrored others using the same interventions-for example, cognitive behavioral therapy (CBT) and physical therapy. A new acupuncture study had similar effectiveness to other acupuncture studies, but higher usual care costs, resulting in higher cost savings. Two new yoga studies' results were similar, but both differed from those of the original yoga study. Mindfulness-based stress reduction was similar to CBT for a typical patient mix but was twice as effective for those with high-impact chronic pain. CONCLUSION: Markov modeling facilitates comparisons across interventions not directly compared in trials, using consistent outcome measures after balancing the baseline mix of patients. Outcomes also differed by pain impact level, emphasizing the need to measure CLBP subgroups. LEVEL OF EVIDENCE: N/A.

Trends of Expenditures and Utilization of Facet Joint Interventions in Fee-For-Service (FFS) Medicare Population from 2009-2018.

BACKGROUND: The trends of the expenditures of facet joint interventions have not been specifically assessed in the fee-for-service (FFS) Medicare population since 2009. OBJECTIVE: The objective of this investigation is to assess trends of expenditures and utilization of facet joint interventions in FFS Medicare population from 2009 to 2018. STUDY DESIGN: The study was designed to analyze trends of expenditures and utilization of facet joint interventions in FFS Medicare population from 2009-2018 in the United States. In this manuscript: • A patient was considered as undergoing facet joint interventions throughout the year. • A visit included all regions treated during the visit. • An episode was considered as one per region utilizing primary codes only. • Services or procedures were considered all procedures (multiple levels). Data for the analysis was obtained from the standard 5% national sample of the Centers for Medicare & Medicaid Services (CMS) physician outpatient billing claims for those enrolled in the FFS Medicare program from 2009 to 2018. All the expenditures were presented with allowed costs and also were inflation adjusted to 2018 US dollars. RESULTS: This analysis showed expenditures increased by 79% from 2009 to 2018 in the form of total cost for facet joint interventions, at an annual rate of 6.7%. Cervical and lumbar radiofrequency neurotomy procedures increased 185% and 169%. However, inflation-adjusted expenditures with 2018 US dollars showed an overall increase of 53% with an annual increase of 4.9%. In addition, using inflation-adjusted expenditures per procedures increased, the overall 6% with an annual increase of 0.7%. Overall, per patient costs, with inflation adjustment, decreased from $1,925 to $1,785 with a decline of 7% and an annual decline of 0.8%. Allowed charges per visit also declined after inflation adjustment from $951.76 to $849.86 with an overall decline of 11% and an annual decline of 1.3%. Staged episodes of radiofrequency neurotomy were performed in 23.9% of patients and more than 2 episodes for radiofrequency neurotomy in 6.9%, in lumbar spine and 19.6% staged and 5.1% more than 2 episodes in cervical spine of patients in 2018. LIMITATIONS: This analysis is limited by inclusion of only the FFS Medicare population, without adding utilization patterns of Medicare Advantage plans, which constitutes almost 30% of the Medicare population. CONCLUSIONS: Even after adjusting for inflation, there was a significant increase for the expenditures of facet joint interventions with an overall 53% increase. Costs per patient and cost per visit declined. Inflation-adjusted cost per year declined 7% overall and 0.8% annually from $1,925 to $1,785, and inflation-adjusted cost per visit also declined 11% annually and 1.3% per year from $952 in 2009 to $850 in 2018. KEY WORDS: Facet joint interventions, facet joint nerve blocks, facet joint neurolysis, facet joint injections, Medicare expenditures.

Evaluation of the efficacy of an internet-based pain education and exercise program for chronic musculoskeletal pain in comparison with online self-management booklet: a protocol of a randomised controlled trial with assessor-blinded, 12-month follow-up, and economic evaluation.

BACKGROUND: Chronic musculoskeletal pain is one of the main causes of years lived with disability and generates the highest cost of health care among chronic pain conditions. Internet-based treatments have been shown to be an alternative for the treatment of musculoskeletal conditions, in addition to reducing barriers such as travel, high demands on the public health system, lack of time, lack of insurance coverage for private care, and high costs for long-term treatment. The aim of this clinical trial is to develop and test the effectiveness and cost-effectiveness of, an internet-based self-management program based on pain education and exercise for people with chronic musculoskeletal pain. METHODS: This is a prospectively registered, assessor-blinded, two-arm randomised controlled trial with economic evaluation comparing the Internet-based pain education and exercise intervention with a control group that will receive an online booklet. One hundred and sixty patients will be recruited from Sao Paulo, Brazil. Follow-ups will be conducted in post-treatment, 6 and 12 months after randomisation. The conduct of the study, as well as the evaluations and follow-ups will be carried out entirely remotely, through online platforms and telephone calls. The primary outcome will be pain intensity at post-treatment (8 weeks) measured using the 11-item Pain Numerical Rating Scale. Secondary outcomes will be biopsychosocial factors presents in the chronic musculoskeletal pain condition. Costs due to chronic musculoskeletal pain will be also measured, and cost-effectiveness analysis from a societal perspective will performed. DISCUSSION: Our hypothesis is that internet-based pain education and exercise will be better than an online booklet in reducing pain and improving biopsychosocial outcomes in patients with chronic musculoskeletal pain. In addition, we believe that there will be good acceptance of patients for the internet-based intervention and that internet-based intervention will be more cost effective than the online booklet. TRIAL REGISTRATION: The study was prospectively registered at ClinicalTrials.gov ( NCT04274439 , registered 18 February 2020).

Effects of participating in community assets on quality of life and costs of care: longitudinal cohort study of older people in England.

OBJECTIVES: Improving outcomes for older people with long-term conditions and multimorbidity is a priority. Current policy commits to substantial expansion of social prescribing to community assets, such as charity, voluntary or community groups. We use longitudinal data to add to the limited evidence on whether this is associated with better quality of life or lower costs of care. DESIGN: Prospective 18-month cohort survey of self-reported participation in community assets and quality of life linked to administrative care records. Effects of starting and stopping participation estimated using double-robust estimation. SETTING: Participation in community asset facilities. Costs of primary and secondary care. PARTICIPANTS: 4377 older people with long-term conditions. INTERVENTION: Participation in community assets. PRIMARY AND SECONDARY OUTCOME MEASURES: Quality-adjusted life years (QALYs), healthcare costs and social value estimated using net benefits. RESULTS: Starting to participate in community assets was associated with a 0.017 (95% CI 0.002 to 0.032) gain in QALYs after 6 months, 0.030 (95% CI 0.005 to 0.054) after 12 months and 0.056 (95% CI 0.017 to 0.094) after 18 months. Cumulative effects on care costs were negative in each time period: £-96 (95% CI £-512 to £321) at 6 months; £-283 (95% CI £-926 to £359) at 12 months; and £-453 (95% CI £-1366 to £461) at 18 months. The net benefit of starting to participate was £1956 (95% CI £209 to £3703) per participant at 18 months. Stopping participation was associated with larger negative impacts of -0.102 (95% CI -0.173 to -0.031) QALYs and £1335.33 (95% CI £112.85 to £2557.81) higher costs after 18 months. CONCLUSIONS: Participation in community assets by older people with long-term conditions is associated with improved quality of life and reduced costs of care. Sustaining that participation is important because there are considerable health changes associated with stopping. The results support the inclusion of community assets as part of an integrated care model for older patients.

[Chronic pain in children and adolescents: an economic perspective]. / Chronischer Schmerz bei Kindern und Jugendlichen: eine ökonomische Betrachtung.

BACKGROUND: Chronic pain is a frequent and disabling health problem in children and adolescents and is associated with high health care utilization and costs. OBJECTIVE: The aim of this study was to analyze the direct and indirect costs of chronic pain in children and adolescents in monetary terms before and after multimodal pain therapy from a societal perspective. MATERIALS AND METHODS: Health care costs 12 months before and after multimodal pain therapy include direct costs from statutory health insurances and parents as well as indirect costs due to working days lost. RESULTS: Direct median costs before multimodal treatment were 5619 € (min-max: 377-35,509 €) per year. In the year after pain therapy, costs decreased to a median of 3262 € (min-max: 142-42,910 €) (p = 0.001). In all, 55% of patients showed a significant cost reduction, while 18% had a cost increase. CONCLUSIONS: An effective multimodal pain therapy may reduce health care costs in children and adolescents. Further economic studies are needed to evaluate long-term effects of pain therapy for children and adolescents with chronic pain in a controlled design.

Clinical- and cost-effectiveness of intensive short-term dynamic psychotherapy for chronic pain in a tertiary psychotherapy service.

OBJECTIVE: The objective of this study is to assess the clinical- and cost-effectiveness of intensive short-term dynamic psychotherapy (ISTDP) for patients with chronic pain. METHOD: A sample of 228 pain patients was drawn from a larger naturalistic study of ISTDP. They received an average of 6.1 sessions delivered by 31 therapists. Psychiatric symptoms and interpersonal problems were assessed at three time points. Healthcare data from baseline year and three years following treatment came from independent governmental databases. RESULTS: Multilevel models indicated significant reductions in symptoms and interpersonal problems during treatment, including a moderate to large pre-post effect size (d = 0.76) for somatization. Further, the sample had successive reductions in yearly healthcare costs, reaching the normal population mean two years post-treatment. CONCLUSION: Within the limitations of the uncontrolled design, our study suggests that ISTDP may be both clinically effective and cost-effective for patients with chronic pain.

Multicentre, double-blind, randomised, sham-controlled trial of 10 khz high-frequency spinal cord stimulation for chronic neuropathic low back pain (MODULATE-LBP): a trial protocol.

INTRODUCTION: Chronic neuropathic low back pain (CNLBP) is a debilitating condition in which established medical treatments seldom alleviate symptoms. Evidence demonstrates that high-frequency 10 kHz spinal cord stimulation (SCS) reduces pain and improves health-related quality of life in patients with failed back surgery syndrome (FBSS), but evidence of this effect is limited in individuals with CNLBP who have not had surgery. The aim of this multicentre randomised trial is to assess the clinical and cost-effectiveness of 10 kHz SCS for this population. METHODS: This is a multicentre, double-blind, randomised, sham-controlled trial with a parallel economic evaluation. A total of 96 patients with CNLBP who have not had spinal surgery will be implanted with an epidural lead and a sham lead outside the epidural space without a screening trial. Patients will be randomised 1:1 to 10 kHz SCS plus usual care (intervention group) or to sham 10 kHz SCS plus usual care (control group) after receiving the full implant. The SCS devices will be programmed identically using a cathodal cascade. Participants will use their handheld programmer to alter the intensity of the stimulation as per routine practice. The primary outcome will be a 7-day daily pain diary. Secondary outcomes include the Oswestry Disability Index, complications, EQ-5D-5 L, and health and social care costs. Outcomes will be assessed at baseline (pre-randomisation) and at 1 month, 3 months and 6 months after device activation. The primary analyses will compare primary and secondary outcomes between groups at 6 months, while adjusting for baseline outcome scores. Incremental cost per quality-adjusted life year (QALY) will be calculated at 6 months and over the lifetime of the patient. DISCUSSION: The outcomes of this trial will inform clinical practice and healthcare policy on the role of high-frequency 10 kHz SCS for use in patients with CNLBP who have not had surgery.

Media representation of chronic pain in Aotearoa New Zealand-a content analysis of news media.

AIM: To analyse how the New Zealand news media has reported on chronic pain and identify whether this publicly available information is reflective of best practice. METHODS: A content analysis of news media published between January 2015 and June 2019, with a primary focus on chronic pain was undertaken. The Factiva, EBSCO and ProQuest databases, alongside popular New Zealand news websites were searched. RESULTS: Two hundred and forty news articles were included; the overarching themes identified in content analysis were (1) the lived experience and the impact of chronic pain (n=119/240), (2) pain management strategies with information on pharmacological (ie, opioids and medicinal cannabis) (n=107/240) and non-pharmacological strategies (eg) psychological therapies (36/240), physical activity (34/240), pain education (34/240), (3) the systemic issues influencing chronic pain healthcare pathways (n=79/240). CONCLUSION: Living with chronic pain is predominantly represented as a struggle, with a lesser focus on the ability to successfully self-manage and live a meaningful life. The limited emphasis on each of the non-pharmacological strategies suggest that the reports failed to communicate that these strategies should be a key component of self-managing chronic pain. New Zealand healthcare providers and researchers can collaboratively work with the media to provide evidence-based information on both non-pharmacological and pharmacological pain management strategies.

Valuing pain using the subjective well-being method.

Chronic pain clearly lowers utility, but valuing the reduction in utility is empirically challenging. Here, we use improvements over prior applications of the subjective well-being method to estimate the implied trade-off between pain and income using four waves of the Health and Retirement Study (2008-2014), a nationally representative survey on individuals age 50 and older. We model income with a flexible functional form, allowing the trade-off between pain and income to vary across income groups. We control for individual fixed effects in the life-satisfaction equations and instrument for income in some models. We find values for avoiding pain ranging between 56-145 USD per day. These results are lower than previously reported and suggest that the higher previous estimates may be heavily affected by the highest income level and confounded by endogeneity in the income variable. As expected, we find that the value of pain relief increases with pain severity.

Opioid epidemics.

In this paper, I propose an economic theory that addresses the epidemic character of opioid epidemics. I consider a community in which individuals are heterogenous with respect to the experience of chronic pain and susceptibility to addiction and live through two periods. In the first period they consider whether to treat pain with opioid pain relievers (OPRs). In the second period they consider whether to continue non-medical opioid use to mitigate cravings from addiction. Non-medical opioid use is subject to social disapproval, which depends negatively on the share of opioid addicts in the community. An opioid epidemic is conceptualized as the transition from an equilibrium at which opioid use is low and addiction is highly stigmatized to an equilibrium at which opioid use is prevalent and social disapproval is low. I show how such a transition is initiated by the wrong belief that OPRs are not very addictive. Under certain conditions there exists an opioid trap such that the community persists at the equilibrium of high opioid use after the wrong belief is corrected. Refinements of the basic model consider the recreational use of prescription OPRs and an interaction between income, pain, and addiction.

[Economic evaluation of interdisciplinary pain rehabilitation. One IKR for rehabilitation gives eight IKR back to society].

INTRODUCTION: There is limited research on the long-term benefits of an interdisciplinary pain rehabilitation, even though short-term benefits have been well documented. The present study evaluated the effects of an interdisciplinary pain rehabilitation program with a three-year follow-up. A special emphasis was placed on economic evaluation of the treatment from a societal perspective. MATERIAL AND METHODS: The study was conducted at the chronic pain unit of the Reykjalundur rehabilitation center. Every fifth patient referred to the Reykjalundur Rehabiliation Center pain clinic was randomized to participate in this study. Data was collected over the course of 4,5 years with a three years follow-up. Finally, economic evaluation was conducted at the end of the research. RESULTS: After treatment patients experienced less pain, fear and avoidance, anxiety and depression symptoms and improved social functioning. Work ability increased from 36% to 47% at the end of rehabilitation and continued to rise to 57% at three year follow-up. Economic evaluation from a societal perspective showed that cost associated with the rehabilitation had leveled out in three years and continued throughout life. CONCLUSION: The results indicate that interdisciplinary rehabilitation for chronic pain has a positive impact on function and the experience of pain as well as positive psychosocial effect. An economic evaluation of the treatment shows that the rehabilitation is very cost effective and that each Icelandic krona (IKR) spent is returned eightfold back to society.
