Lage-Hansen PR, Chrysidis S, Amris K, Fredslund-Andersen S, Christensen R, Ellingsen T. Prevalence of survey-based criteria for fibromyalgia and impact on hospital burden: a 7 year follow-up study from an outpatient clinic. Scand J Rheumatol 2023; 52:539-548. [PMID: 36503382 DOI: 10.1080/03009742.2022.2145703] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 11/07/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVES To evaluate the prevalence of survey-based criteria for fibromyalgia (FM) among newly referred patients in a rheumatic outpatient clinic, and to compare the use of secondary healthcare services between survey-based FM and non-FM cases. METHOD Newly referred patients to an outpatient clinic were screened for the fulfilment of the 2011 FM survey criteria during a 6 month period in 2013 in this observational cohort study. Demographic data were obtained at baseline. Patients' medical files were evaluated and comparisons between groups were made regarding the use of hospital healthcare facilities during the 7 year observation period. RESULTS Out of 300 invited patients, 248 (83%) completed the questionnaire; 90 patients (36%) fulfilled survey-based criteria for FM at enrolment. FM cases were primarily women (80% vs 54% of non-FM cases), and received more medications (median 4 vs 3 drugs) and public economic support (62% vs 20%). At the 7 year follow-up, crude analyses showed that FM cases had a higher number of hospital courses (median 10 vs 8) and had undergone more invasive procedures (78% vs 60%). Neurologists (42% vs 28%), gastroenterologists (30% vs 13%), endocrinologists (40% vs 21%), pain specialists (13% vs 3%), psychiatrists (20% vs 7%), and abdominal surgeons (43% vs 30%) were consulted more often by FM than by non-FM cases. CONCLUSION Fulfilment of FM survey criteria among newly referred patients to a rheumatic outpatient clinic is frequent. Our study findings show that FM continues to present a challenge for healthcare professionals as well as for patients. RESEARCH HIGHLIGHTS ● Fulfilment of FM survey criteria among newly referred patients to a rheumatic outpatient clinic is frequent.● The burden on the secondary healthcare system for these patients is significant.● This study suggests the need for increased awareness about the diagnosis of FM among certain medical and surgical specialties.

Health, Psychological and Demographic Predictors of Depression in People with Fibromyalgia and Osteoarthritis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19063413. [PMID: 35329109 PMCID: PMC8950397 DOI: 10.3390/ijerph19063413] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 03/09/2022] [Accepted: 03/10/2022] [Indexed: 02/04/2023]
Abstract
Depression is common in people with fibromyalgia (FM) and osteoarthritis (OA) and has been linked to adverse health outcomes in these conditions. The purpose of this study was to examine differences in predictors of depression among individuals with FM and OA using a range of health, demographic, and psychological variables. Of the total 963 participants, 600 were diagnosed with FM, and 363 with OA. The Quality of Well-Being Scale (QWB) was used to assess health status. The Fibromyalgia Impact Questionnaire (FIQ) and the Arthritis Impact Measurement Scale (AIMS) were used to measure disease-specific impact. Additionally, participants completed self-efficacy and helplessness assessments. Depression was measured using the Center for Epidemiological Studies Scale (CES-D). The results of a moderated linear regression showed that higher depression scores were associated with lower health status and a greater condition impact, especially in the FM group. Self-efficacy and helplessness predicted depression in both groups, but more strongly in FM. White participants with OA were more depressed than their non-White counterparts, while the opposite was true for FM. These findings indicate that improving health status and psychological well-being might alleviate depression in both FM and OA.

Abstract
BACKGROUND Despite a national focus on achieving health equity, limited attention has been paid to behavioral and pediatric health disparities. As the most common pediatric neurobehavioral disorder, attention-deficit/hyperactivity disorder (ADHD) provides an opportunity to assess the status of pediatric behavior health disparities. The purpose of this literature review is to provide a synthesis of existing research on ADHD diagnostic and treatment disparities between African American and White children. METHODS Studies were systematically identified through searches in PubMed, CINAHL, and APA PsycInfo using the terms attention-deficit/hyperactivity disorder, disparity, race, ethnicity, diagnosis, medication, and treatment. Summary calculations were conducted to report the proportions of studies with statistically significant differences in ADHD diagnosis and treatment between White and African American children, and to describe trends in disparities over time. RESULTS Forty-one studies were included in this review. The majority of studies identified significant disparities in ADHD diagnosis and medication treatment between African American and White children. While diagnostic disparities show a trend toward reduction over time, a similar trend was not observed in medication treatment disparities. This synthesis provides a critique of the existing literature and recommendations for practice and future research.

J Clin Med 2021; 10:2706. [PMID: 34205244 PMCID: PMC8235706 DOI: 10.3390/jcm10122706] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 06/15/2021] [Accepted: 06/18/2021] [Indexed: 12/27/2022] Open
Abstract
OBJECTIVES Acceptance and commitment therapy (ACT) is considered by the American Psychological Association as an evidence-based treatment for a variety of disorders, including chronic pain. The main objective of the present systematic review was to determine the effectiveness of ACT in patients with central pain sensitization syndromes (CPSS). METHODS This systematic review was conducted according to the guidelines of the Cochrane Collaboration and PRISMA statements. The protocol was registered in advance in the Prospective Register of Systematic Reviews (PROSPERO) international database. The selected articles were evaluated using the Cochrane risk of bias (ROB) assessment tool. The PubMed, Scopus, and Web of Science databases were searched. RESULTS The literature search identified 21 studies (including investigations of fibromyalgia syndrome, irritable bowel syndrome, and migraine) eligible for the systematic review. There were no studies regarding the effectiveness of ACT for chronic tension-type headache (CTTH), interstitial cystitis (IC), or temporomandibular disorder (TMD). The evaluation of ROB showed that 12 of the selected studies were of low quality, 5 were of moderate quality, and 4 were high quality. ACT reduces some clinical symptoms, such as anxiety, depression, and pain. This positive effect of ACT might be mediated by pain acceptance, psychological flexibility, optimism, self-efficacy, or adherence to values. ACT showed better results in comparison to non-intervention (e.g., "waiting list") conditions, as well as pharmacological and psychoeducational interventions. It is not entirely clear whether extended ACT treatments are more advantageous than briefer interventions. CONCLUSIONS There are few studies about the effectiveness of ACT on CPSS. However, ACT seems to reduce subjective CPSS symptoms and improve the health-related quality of life of these patients. The absence of studies on the effectiveness of ACT in CTTH, IC, and TMD, indicate the pressing need for further ACT studies in these CPSS.

Abstract
[Purpose] The aim of this study was to compare Visual Analog Scale (VAS) values with the
Shear Wave Elastography (SWE) values of rhomboid major muscles in fibromyalgia (FM)
patients with those of a normal healthy population. [Participants and Methods] Evaluation
was made of 53 female patients diagnosed with FM according to the American Collage of
Rheumatology criteria, and a control group of 47 healthy volunteers with a VAS score of 0.
All the patients were applied with ultrasonography. The severity of pain was measured
using a VAS. [Results] Mean age was calculated as 39 years (range, 23–60 years) in the
patient group and 37 years (range, 21–58 years) in the control group. The mean SWE value
of the rhomboid major muscle of the patients was 4.74 m/sn and 70.21 kPa on the right side
and 4.46 m/sn and 58.78 kPa on the left side. In the control group, these values were
4.18m/sn and 55.03 kPa on the right side and 3.78 m/sn and 44.21 kPa on the left side. The
mean VAS score of the patients was 7.3. [Conclusion] The use of SWE values could be more
objective than the subjective parameter of the VAS score in the evaluation of the severity
of pain in fibromyalgia.

Abstract
Background Chronic pain conditions, such as fibromyalgia, adversely affect individuals’ abilities to work. Aim The aim of this study was to examine, from the perspective of patients, the effects that fibromyalgia symptoms had on their ability to work, the challenges that they encountered in the workplace that did not foster their continued employment, and the types of modifications to their work or workplace that they thought would facilitate their productivity and ability to work. Methods A scoping review method, applying techniques of systematic review, was used to conduct a research synthesis of the literature regarding fibromyalgia and work that looked at this issue from the patient perspective. Results A variety of themes emerged from the analysis and could be broadly categorized into (1) the work experience was a challenging one with which to cope; (2) relationships were strained at work; (3) clinical symptoms had repercussions on subjects’ attitudes toward work and the relation to life outside of work; and (4) a variety of possible solutions were considered to help subjects better cope with fibromyalgia and work. Conclusions Strategies that potentially could foster continued employment of patients with fibromyalgia include those at the micro, meso, and macro levels. Health care providers can support patients’ employment goals by collaborating with patients and their employers, dispelling stigma regarding the illness, and providing practical and specific advice regarding workplace accommodations.

Abstract
BACKGROUND Somatic symptom disorder (SSD) is characterized by a persistent and distressing psychological reaction to somatic symptoms. In pain disorders, the preoccupation with physical symptoms is associated with poor long-term outcomes. SSD may therefore be of use to identify and help chronic pain patients with particular needs. OBJECTIVE To test the hypothesis that in fibromyalgia, SSD is associated with higher anxiety sensitivity, health anxiety, and reactivity to pain, in addition to lower nonreactivity to inner experiences. In addition, to investigate if individuals with SSD report a larger impact of fibromyalgia core symptoms, more somatic symptoms, and higher psychiatric comorbidity. METHODS Using data from a clinical trial involving self-referred individuals with fibromyalgia, we compared participants with SSD to participants without SSD using t-tests and logistic regression. RESULTS Forty-nine out of 140 participants (35%) had SSD. Most findings corroborate that individuals with fibromyalgia who also meet criteria for SSD are worse off in terms of traits previously found to be predictive of a poor course in pain disorders. Post hoc analyses indicated that this could not be explained merely by a higher level of fibromyalgia core symptoms. CONCLUSION SSD appears to be associated with a higher symptom burden in fibromyalgia, but further research is needed to draw firm conclusions regarding the reliability, acceptability, and utility of the SSD diagnosis in the clinic.

Abstract
Abstract
Background
The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 is a generic instrument to assess disability. Pain and psychological factors seem to play a pronounced disabling role in fibromyalgia (FM). There are few studies that investigate the factors associated with disability in patients with fibromyalgia from the patient’s perspective. Information about FM disability using self-reported questionnaires is limited. This study aimed to assess the relationship between the ordinal response variable (degree of disability), and four explanatory variables: pain intensity, depression, anxiety, and alexithymia.
Methods
One hundred fifteen women with FM were enrolled in the cross-sectional study. For the assessment of disability the WHODAS 2.0 (36-item version) was used. Univariate and multivariate (ordinal logistic regression) analyses were performed to assess the relationship between pain (Visual Analogue Scale), depression and anxiety (Hospital Anxiety and Depression Scale), alexithymia (Modified Toronto Alexithymia Scale) and disability.
Results
Disability was detected by global WHODAS score in 114 patients (99%), with the corresponding percentages for mild, moderate and severe disability being 11.3, 46.96 and 40.87%, respectively. Global WHODAS score was more severe among subjects with depression (50 vs 36.4, p < 0.001, effect size = 0.33) and alexithymia (50 vs 33.6, p < 0.001, effect size = 0.38). Pain intensity mean scores for mild, moderate and severe disability were 5.0, 6.1 and 7.3, respectively (p < 0.001, omega-squared = 0.12). Pain intensity explained the global disability degree and its domains except for the cognitive one. Whereas, depression explained cognitive and personal relation domains. On the other hand, alexithymia explained global disability degree and all domains of WHODAS 2.0 questionnaire.
Conclusions
Most of the patients with fibromyalgia perceived themselves with moderate to severe disability. The main explanatory variables of the perceived disability were the pain intensity and psychological factors (alexithymia and depression).

ASIA-PACIFIC JOURNAL OF SPORT MEDICINE ARTHROSCOPY REHABILITATION AND TECHNOLOGY 2018; 15:23-28. [PMID: 30581756 PMCID: PMC6289903 DOI: 10.1016/j.asmart.2018.11.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/18/2018] [Revised: 11/16/2018] [Accepted: 11/20/2018] [Indexed: 01/03/2023]
Abstract
Objectives The role of arthroscopic debridement in the painful degenerative knee is controversial. Studies have shown that arthroscopic surgery for knee osteoarthritis provides no additional benefit to optimized physical and medical therapy. There are however, limited studies on the management of the subgroup of significantly symptomatic patients who remain refractory to maximal conservative treatment and are poor candidates for knee replacement surgery.We propose that with careful patient selection, arthroscopic debridement can provide good symptomatic relief with sustained benefits in the degenerative knee. Methods We performed a retrospective, single-surgeon study of 180 consecutive knee arthroscopies performed in 169 patients, aged 40 years and above, who had mechanical symptoms affecting their daily lives and underwent arthroscopic debridement after failure of a minimum 2 months of optimized medical and physical therapy. Severity of the knee osteoarthritis on plain radiographs was assessed using the Kellgren-Lawrence classification.Functional and satisfaction scores were assessed using Oxford Knee Score, Koos Knee Survey, Short Form-36, Numeric Pain Rating Scale, and questions adapted from the North American Spine Society Questionnaire. Results Excellent functional outcomes and patient satisfaction were reported in the majority of patients over the follow-up timeframe of 2-8 years. The mean pre-operative Kellgren-Lawrence score was 2.02 (SD 0.580). Significant improvements compared to pre-operative scores were seen across all scoring systems tested. 90% of patients reported good to excellent results. Conclusion Arthroscopic knee debridement can provide good symptomatic relief and sustained benefits in significantly symptomatic patients with early degenerative knees who have failed conservative management. This is most useful in patients with mechanical symptoms secondary to degenerative meniscal tears or chondral flaps, and those with symptomatic patellofemoral osteoarthritis.

Abstract
Background and aims Despite the enormous body of literature spanning more than 50 years describing results of pain experiments, very few have used qualitative methods to explore subjects' thoughts while scoring experimental painful stimuli, and none in the available literature have used qualitative interviews to do so. The current study examined how participants in experimental pain research delineate pain ratings to better understand the unique influences of the experimental setting on pain scores. An additional aim was to highlight how individuals with fibromyalgia and healthy volunteers are differently influenced by characteristics of the experimental setting. Methods This was an inductive, qualitative study in which individual, semi-structured interviews were performed with 31 fibromyalgia patients and 44 healthy volunteers. Participants had taken part in a pain experiment during which a thermode was used to induce painful heat stimuli on two skin areas. There were two primary interview questions analyzed for this report: (1) "Thinking back to when you were getting the heat pain on your leg, what were you thinking about when deciding on your pain score?" and (2) Participants who said that it was difficult to decide on a pain score were asked to, "Describe what made it difficult to choose a number." Thematic analysis was used to generate conceptual categories from textual data and find common themes. Results Three notable differences were found between fibromyalgia patients and healthy volunteers: (1) using current daily pain as a benchmark was seen more in patients, (2) wanting to appear strong in front of the study investigators was more common in healthy volunteers, and (3) becoming mentally fatigued from rating many stimuli was more common for fibromyalgia patients. Thoughts while scoring pain included: (1) comparing with previous or current pain, (2) self-monitoring of one's ability to endure the pain, (3) focusing on the physical aspects of the pain, (4) knowing the experimental setting is safe, (5) focusing on the pain scale as an anchor, and (6) desire to appear strong. Additionally, five difficulties in scoring experimental pain were identified: (1) falling asleep, (2) mentally fatigued, (3) feeling as though they were guessing, (4) having to make a quick decision, and (5) difficulty in being consistent. Conclusions This study provides insights into the thoughts of participants in experimental pain research studies. Participants were distracted and influenced by the experimental setting and some factors differed for fibromyalgia patients versus healthy volunteers. Implications Understanding the ways in which the experimental setting influences pain ratings may help pain researchers better design and interpret studies. Researchers can use these findings to mitigate difficulties for participants in experimental research to add to its validity.

Abstract
OBJECTIVE To examine medication adherence and healthcare costs for combination prescription initiators (duloxetine/milnacipran/venlafaxine with pregabalin) vs. monotherapy initiators (duloxetine, milnacipran, venlafaxine, and pregabalin) among patients with fibromyalgia syndrome (FMS). METHODS Our retrospective cohort study used claims data for the South Carolina Blue Cross Blue Shield State Health Plan (SHP). Patients with FMS ≥ 18 years of age, with prescription initiation from July 1, 2007, through June 30, 2010, and SHP enrollment for 12 months pre- and post-index periods were included (combination: n = 100; pregabalin: n = 665; duloxetine: n = 713; milnacipran: n = 131; venlafaxine: n = 272). Medication adherence measures included high adherence (medication possession ratio ≥ 80%) and total supply days. Healthcare costs comprised direct medical expenditures. Propensity score methods of inverse probability of treatment weights were used to control for selection bias due to differing pre-index characteristics. RESULTS Odds ratios for high adherence were significantly increased (P < 0.05) among the combination cohort vs. the venlafaxine (2.15), duloxetine (1.39), and pregabalin (2.20) cohorts. Rate ratios for total supply days were significantly higher (P < 0.05) for combination vs. venlafaxine (1.23), duloxetine (1.08), and pregabalin (1.32) cohorts. Expenditures for total health care were significantly higher (P < 0.05) for combination vs. duloxetine ($26,291 vs. $17,190), milnacipran ($33,638 vs. $22,886), and venlafaxine ($26,586 vs. $16,857) cohorts. CONCLUSIONS Medication adherence was considerably better for combination prescription initiators; however, expenditures for total health care were higher. Still, our findings suggest important clinical benefits with the use of combination prescription therapy, and prospective studies of medication adherence are warranted to examine causal relationships with outcomes not captured by healthcare claims databases.

Abstract
AIM This study was conducted to evaluate the effects of local cold application on pain when applied to the trapezius muscles of patients with fibromyalgia. METHOD A one-group, pre-test/post-test, pre-experimental model was applied in this study, which was conducted with 55 fibromyalgia patients who presented to a rheumatology outpatient clinic. A 10-min cold application was administered to one trapezius muscle of each patient. The participants' pain was evaluated, in total, four times (before the cold application and 10 min, 1.5 h and 24 h after the cold application). The visual analogue scale (VAS) for pain was used to collect data for the study, and Friedman and Wilcoxon tests were used to assess the data. RESULTS The patients' pain mean score before (6.45, SD:1.27) the cold applications was found to be significantly higher than the scores noted 10 min (2.75, SD:1.73), 1.5 h (2.45, SD:1.29), and 24 h (3.36, SD:1.30) after the application (P < 0.001). CONCLUSION The study found that local cold applications performed on the trapezius muscles of patients with fibromyalgia significantly decreased their pain. With its discovery of a new method of pain control in fibromyalgia patients, this study will significantly contribute to science and will serve as a guide for pain management, especially in nursing practice. Further studies to evaluate the maximum effect duration and effect mechanisms of local cold applications to the trapezius muscles of FM patients are indicated.

Abstract
BACKGROUND Fibromyalgia (FM) is characterized by persistent widespread pain, increased pain sensitivity and tenderness. People with FM also report activity limitations and impaired work ability. OBJECTIVE This article aims to compile the findings of recently published research on work ability in people with fibromyalgia, and to present how work ability is influenced by various aspects. METHODS A systematic search of the literature published from the year 2000 and onwards was conducted. Thirtyfour articles were included in the review. RESULT Symptom severity was found to influence work ability in people with FM. Physically demanding jobs and work tasks were especially troublesome and were reported to constitute higher risks pof work disability. Working people with FM seemed to hold a careful balancing act to manage the risk of overload where well-functioning strategies such as making a career change, working part-time, and developing personal skills were necessary for managing work, in the short- and long term. The support of management and colleagues enabled people with FM to manage the risk of overload at work. Treatment studies evaluating work disability as outcome in FM are scarce. None of the included studies presented any effects on measures of sick-leave or work disability compared with a control group. CONCLUSION More studies of treatment effects on outcomes related to work ability in people with FM, and more longitudinal studies to explore long-term effects of symptoms on work ability and sick leave, are needed in order to be able to plan evidence based rehabilitation to improve or maintain work ability in people with FM.

Abstract
BACKGROUND Osteoarthritis (OA) consumes a significant amount of healthcare resources, and impairs the health-related quality of life (HRQoL) of patients. Previous reviews have consistently found substantial variations in the costs of OA across studies and countries. The comparability between studies was poor and limited the detection of the true differences between these studies. OBJECTIVE To review large sample studies on measuring the economic and/or humanistic burden of OA published since May 2006. METHODS We searched MEDLINE and EMBASE databases using comprehensive search strategies to identify studies reporting economic burden and HRQoL of OA. We included large sample studies if they had a sample size ≥1000 and measured the cost and/or HRQoL of OA. Reviewers worked independently and in duplicate, performing a cross-check between groups to verify agreement. Within- and between-group consolidation was performed to resolve discrepancies, with outstanding discrepancies being resolved by an arbitrator. The Kappa statistic was reported to assess the agreement between the reviewers. All costs were adjusted in their original currency to year 2015 using published inflation rates for the country where the study was conducted, and then converted to 2015 US dollars. RESULTS A total of 651 articles were screened by title and abstract, 94 were reviewed in full text, and 28 were included in the final review. The Kappa value was 0.794. Twenty studies reported direct costs and nine reported indirect costs. The total annual average direct costs varied from US$1442 to US$21,335, both in USA. The annual average indirect costs ranged from US$238 to US$29,935. Twelve studies measured HRQoL using various instruments. The Short Form 12 version 2 scores ranged from 35.0 to 51.3 for the physical component, and from 43.5 to 55.0 for the mental component. Health utilities varied from 0.30 for severe OA to 0.77 for mild OA. CONCLUSION Per-patient OA costs are considerable and a patient's quality of life remains poor. Variations in costing methods are a barrier to understanding the true differences in the costs of OA between studies. Standardizing healthcare resource items, the definition of OA-relevant costs, and productivity loss measures would facilitate the comparison.

Abstract
BACKGROUND This study aimed at describing pain-related health care resource use, direct costs, and productivity loss among patients suffering from fibromyalgia syndrome (FMS). METHODS A cost-of-illness study with a sample of 57 adults having a diagnosis of FMS was conducted in the province of Quebec (Canada). Data regarding FMS-related direct costs and productivity loss from paid and unpaid work over a three-month period were collected using a standardized structured telephone interview protocol. Direct costs were valued in 2009 Canadian dollars using a societal perspective. RESULTS Results showed that average direct costs over a three-month period added up to $951 per patient (SD: $710), which could be translated in a mean annual cost of $3804. The purchase of prescribed medications led to the highest costs (mean: $329, SD: $321), followed by consultations to health care professionals other than physicians (mean: $129, SD: $222) and physicians consultations (mean: $98, SD: $116). Results further showed a high economic burden for patients themselves, aside from costs covered by public or private insurers. Among the subsample of participants who had a paid job (45.6%), an average of 5.6 days (SD: 13.2) were lost due to pain during the past three months. Among those who were not employed (54.4%), an average of 25.1 days in household productivity (SD: 24.8) were lost. CONCLUSIONS FMS is associated with a substantial socioeconomic burden. Further research is clearly needed to improve the management of this type of disorder and make better decisions regarding resource allocation.

Abstract
A substantial amount of healthcare and costs are attributable to arthritis, which is a very common chronic disease. This paper presents the results of a systematic review of arthritis cost studies published from 2008 to 2013. MEDLINE, Embase, EconLit databases were searched, as well as governmental and nongovernmental organization websites. Seventy-one reports met the inclusion/exclusion criteria, and 24 studies were included in the review. Among these studies, common methods included the use of individual-level data, bottom-up costing approach, use of both an arthritis group and a control group to enable incremental cost computation of the disease, and use of regression methods such as generalized linear models and ordinary least squares regression to control for confounding variables. Estimates of the healthcare cost of arthritis varied considerably across the studies depending on the study methods, the form of arthritis and the population studied. In the USA, for example, the estimated healthcare cost of arthritis ranged from $1862 to $14,021 per person, per year. The reviewed study methods have strengths, weaknesses and potential improvements in relation to estimating the cost of disease, which are outlined in this paper. Caution must be exercised when these methods are applied to cost estimation and monitoring of the economic burden of arthritis.

Abstract
OBJECTIVE To provide an accurate representation of the economic burden of arthritis by estimating the adjusted incremental healthcare cost of arthritis at multiple percentiles and reporting the cost trends across time. METHODS A healthcare cost study based on health survey and linked administrative data, where costs were estimated from the government's perspective in dollars per person per year. Quantile regression was used to estimate the adjusted incremental cost at the 25th, 50th, 75th, 90th, and 95th percentiles. RESULTS Data from 4287 older Australian women were included. The median incremental healthcare cost of arthritis was, in 2012 Australian dollars, $480 (95% CI: $498-759) in 2009; however, 5% of individuals had 5-times higher costs than the 'average individual' with arthritis. Healthcare cost of arthritis did not increase significantly from 2003 to 2009. CONCLUSION Healthcare cost of arthritis represents a substantial burden for the governments. Future research should continue to monitor the economic burden of arthritis.

Abstract
BACKGROUND Adjudication of disability claims related to fibromyalgia (FM) syndrome can be a challenging and complex process. A commentary published in the current issue of Pain Research & Management makes suggestions for improvement. The authors of the commentary contend that: previously and currently used criteria for the diagnosis of FM are irrelevant to clinical practice; the opinions of family physicians should supersede those of experts; there is little evidence that trauma can cause FM; no formal instruments are necessary to assess disability; and many FM patients on or applying for disability are exaggerating or malingering, and tests of symptoms validity should be used to identify malingerers. OBJECTIVES To assess the assertions made by Fitzcharles et al. METHODS A narrative review of the available research literature was performed. RESULTS Available diagnostic criteria should be used in a medicolegal context; family physicians are frequently uncertain about FM and⁄or biased; there is considerable evidence that trauma can be a cause of FM; it is essential to use validated instruments to assess functional impairment; and the available tests of physical effort and symptom validity are of uncertain value in identifying malingering in FM. CONCLUSIONS The available evidence does not support many of the suggestions presented in the commentary. Caution is advised in adopting simple solutions for disability adjudication in FM because they are generally incompatible with the inherently complex nature of the problem.

Abstract
OBJECTIVE To examine the factors associated with higher healthcare cost in women with arthritis, using generalized linear models (GLMs) and quantile regression (QR). METHODS This is a cross-sectional healthcare cost study of individuals with arthritis that focused on older Australian women. Cost data were drawn from the Medicare Australia datasets. RESULTS GLM results show that healthcare cost was significantly associated with various socio-demographic and health factors. Although QR analysis results show the same direction of association between these factors and healthcare cost as in the GLMs, they indicate progressively increased effect sizes at the 50th, 75th, 90th and 95th percentiles. CONCLUSION Findings suggest traditional regression models such as GLMs that assume a single rate of change to accurately describe the relationships between explanatory variables and healthcare costs across the entire distribution of cost can produce biased results. QR should be considered in future healthcare cost research.

Abstract
OBJECTIVE The burden of illness that can be attributed to osteoarthritis is considerable and ever increasing. The aim of this systematic review is to analyze currently available data derived from cost-of-illness studies on the healthcare and non-healthcare costs of osteoarthritis. METHODS PubMed, Index Medicus Español (IME), and the Spanish Database of Health Sciences [Índice Bibliográfico Español en Ciencias de la Salud (IBECS)] were searched up to the end of April 2013. This study adhered to the PRISMA guidelines. Articles were reviewed and the study quality assessed by two independent investigators with consensus resolution of discrepancies. RESULTS We identified 39 studies that investigated the socio-economic cost of osteoarthritis. Only nine studies took a social perspective. Rather than estimating the incremental cost of osteoarthritis, nine studies estimated the total cost of treating patients with osteoarthritis without a control for comorbidity. The other 30 studies determined the incremental cost with or without a control group. Only nine studies assessed a comprehensive list of healthcare resources. The annual incremental healthcare costs of generalized osteoarthritis ranged from €705 to €19,715. The annual incremental non-healthcare-related costs of generalized osteoarthritis ranged from €432 to €11,956. CONCLUSIONS The study concludes that the social cost of osteoarthritis could be between 0.25% and 0.50% of a country׳s GDP. This should be considered in order to foster studies that take into account both healthcare and non-healthcare costs.

Abstract
Fibromyalgia (FM) is a debilitating chronic condition that often affects women in midlife with widespread pain that interrupts attempts to exercise. The purpose of this pilot study was to test the efficacy of calf muscle pump (CMP) stimulation as an adjuvant therapy for FM by (1) assessing the correlation of the level of symptoms, as measured by the revised Fibromyalgia Impact Questionnaire (FIQR), and blood pressure (BP), (2) measuring change in mean FIQR scores for subjects who use a CMP-stimulation device for 12 weeks, and (3) measuring the correlation of total device usage and the level of symptoms as measured by the FIQR. The 29 male and female participants (mean age = 47.3 years) were screened using the Widespread Pain Index (WPI), Symptom Severity (SS) score, and the FIQR. Participants were contacted weekly, and progress was assessed using the WPI, SS score, and the FIQR as well as general questions regarding responses to CMP stimulation. The attrition rate was high, which is not uncommon in studies of patients with FM. We found that diastolic BP was significantly inversely correlated with baseline FIQR scores during quiet sitting. Further, 12 weeks of CMP stimulation was associated with significant improvement in average FIQR scores at a rate of approximately -1.5 points per week (R (2) = .9; p ≤ .0001). Total device usage was strongly and inversely correlated with baseline FIQR scores (R (2) = .43; p = .02). These findings suggest that CMP stimulation may provide an additional treatment option for individuals with FM who are challenged to perform traditional forms of exercise.

Abstract
Fibromyalgia (FM) is a complex disorder that affects up to 5% of the general population worldwide, more frequently in women than in men. In addition to chronic widespread pain, patients with FM usually experience other characteristic symptoms, including fatigue, disturbed sleep, stiffness, reduced functioning, dyscognition, and depressed mood. Many patients also have comorbid conditions such as depression, irritable bowel syndrome, temporomandibular disorder, or migraine. Although the etiology of FM remains unclear, evidence suggests that biologic, genetic, and environmental factors are involved. The variability of symptoms and the frequency of comorbidities among patients with FM make this a difficult disorder to diagnose. Diagnosis may be further complicated by the stigmatization of this disorder among treatment providers, the health insurance industry, and the general population. Treating chronic pain disorders such as FM can be time consuming and costly, and other issues such as polypharmacy, treatment adherence, and access to treatment often need to be addressed. The aim of this article is to provide physicians with a general overview of FM, including a brief review of the pathophysiology that explains the biologic and genetic bases of this disorder. Also included is a synopsis of new diagnostic criteria and other useful diagnostic tools and a discussion of various treatment challenges and strategies.

Abstract
PURPOSE To examine and describe the factors promoting sustainable work in women with fibromyalgia (FM). METHODS A qualitative interview study. Twenty-seven gainfully employed women with FM participated in five focus group interviews. Their median age was 52 years, ranging from 33 to 62. The interviews were recorded, transcribed verbatim and analysed by qualitative latent content analysis. RESULTS Four categories were identified describing factors promoting sustainable work: the meaning of work and individual strategies were individual promoters while a favourable work environment and social support outside work were environmental promoters. The meaning of work included individual meaning and social meaning. The individual strategies included handling symptoms, the work day and long-term work life. A favourable work environment included the physical and psychosocial work environment. Social support outside work included societal and private social supports. CONCLUSIONS Promoting factors for work were identified, involving individual and environmental factors. These working women with FM had developed advanced well-functioning strategies to enhance their work ability. The development of such strategies should be supported by health-care professionals as well as employers to promote sustainable work in women with FM. IMPLICATIONS FOR REHABILITATION Work disability is a common consequence of fibromyalgia (FM). Working women with FM appear to have developed advanced well-functioning individual strategies to enhance their work ability. The development of individual strategies should be supported by health-care professionals as well as employers to promote sustainable work and health in women with FM.

Abstract
OBJECTIVE To estimate the annualized differences in direct medical and indirect costs associated with improvement in fibromyalgia (FM) severity among pregabalin-treated patients. METHODS Data from three clinical trials of pregabalin in patients with FM were modeled; efficacy results were extrapolated. Mean annual costs (direct and indirect) were assigned based on FM severity levels (mild: $10,219; moderate: $26,217; severe: $42,456). FM severity levels were defined using established cut-points on the Fibromyalgia Impact Questionnaire (FIQ). Mean annualized costs at end-point were estimated for all patients within each cohort and the mean differences in costs were compared using a regression model. RESULTS Relative to placebo, there was a significantly higher proportion of subjects with mild FM at end-point with pregabalin 450 mg and a significantly lower proportion of subjects with severe FM. Mean total costs were lower with pregabalin (300 mg, $25,721; 450 mg, $24,103) than placebo ($26,162). The difference in mean annual costs was $2059 lower for pregabalin 450 mg (p = 0.003) and $441 lower for pregabalin 300 mg (p = 0.52). Mean direct medical costs were higher with pregabalin (300 mg, $4962; 450 mg, $4820) than placebo ($4364). The difference in mean annual direct medical costs was significantly higher for pregabalin 450 mg by $456 (p < 0.0001) and by $599 for pregabalin 300 mg (p < 0.0001). Mean indirect costs for pregabalin (300 mg, $20,783; 450 mg, $19,306) were lower than placebo ($21,735). The difference in mean annual indirect costs for pregabalin 450 mg was lower by $2429 (p < 0.0001); pregabalin 300 mg was lower by $951 (p = 0.12). LIMITATIONS Use of 13-week end-point data from clinical trials to extrapolate to annual costs and an assumption of continuous therapy over the course of 1 year. CONCLUSIONS Improvements in FM severity were associated with overall reductions in cost. Reductions in indirect costs may offset the costs of treatment with pregabalin.

Abstract
OBJECTIVE To systematically review the literature to date applying repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) for patients with fibromyalgia syndrome (FMS). METHOD Electronic bibliography databases screened included PubMed, Ovid MEDLINE, PsychINFO, CINAHL, and Cochrane Library. The keyword "fibromyalgia" was combined with ("transcranial" and "stimulation") or "TMS" or "tDCS" or "transcranial magnetic stimulation" or "transcranial direct current stimulation". RESULTS Nine of 23 studies were included; brain stimulation sites comprised either the primary motor cortex (M1) or the dorsolateral prefrontal cortex (DLPFC). Five studies used rTMS (high-frequency-M1: 2, low-frequency-DLPFC: 2, high-frequency-DLPFC: 1), while 4 applied tDCS (anodal-M1: 1, anodal-M1/DLPFC: 3). Eight were double-blinded, randomized controlled trials. Most (80%) rTMS studies that measured pain reported significant decreases, while all (100%) tDCS studies with pain measures reported significant decreases. Greater longevity of significant pain reductions was observed for excitatory M1 rTMS/tDCS. CONCLUSION Studies involving excitatory rTMS/tDCS at M1 showed analogous pain reductions as well as considerably fewer side effects compared to FDA apaproved FMS pharmaceuticals. The most commonly reported side effects were mild, including transient headaches and scalp discomforts at the stimulation site. Yearly use of rTMS/tDCS regimens appears costly ($11,740 to 14,507/year); however, analyses to apapropriately weigh these costs against clinical and quality of life benefits for patients with FMS are lacking. Consequently, rTMS/tDCS should be considered when treating patients with FMS, particularly those who are unable to find adequate symptom relief with other therapies. Further work into optimal stimulation parameters and standardized outcome measures is needed to clarify associated efficacy and effectiveness.

Abstract
OBJECTIVE To estimate direct and indirect economic costs among private-sector employees with osteoarthritis (OA). METHODS Using a large US employer benefits database, we identified all employees with evidence of OA during calendar year 2007, and compared their costs of health care and work loss to age-and-sex-matched employees without evidence of OA in that year. RESULTS Private-sector employees with OA (n = 2399) averaged 62.9 days of absenteeism versus 36.7 days among matched comparators (n = 2399) (P < 0.01). Mean total direct costs among these persons were $17,751 and $5057, respectively (P < 0.01); 34% of health care costs among persons with OA arose from medical encounters with listed diagnoses of OA. Mean total indirect costs were two-fold higher among persons with OA ($5002 versus $2120 for those without OA; P < 0.01). CONCLUSIONS Private-sector employees with OA have higher direct and indirect costs than those without this condition.

Abstract
Background Although osteoarthritis (OA) often affects older persons, it has a profound effect on individuals actively employed. Despite reports of reduced productivity among workers with OA, data are limited regarding the impact of OA among workers. The objective of this study was to evaluate the impact of self-rated OA severity on quality of life, healthcare resource utilization, productivity and costs in an employed population relative to employed individuals without OA. Methods This cross-sectional analysis used data derived from the 2009 National Health and Wellness Survey (NHWS). Multivariable analyses characterized outcomes and costs (direct medical costs and indirect) among workers (full-time, part-time, or self-employed) ≥ 20 years of age who were diagnosed with OA and who self-rated their OA severity as mild, moderate, or severe relative to workers without OA. Evaluated outcomes included productivity, assessed using the Work Productivity and Impairment (WPAI) scale; health-related quality of life, using the SF-12v2 Health Survey; and healthcare resource utilization. Results 4,876 workers reported being diagnosed with OA (45.0% mild, 45.9% moderate, and 9.1% severe); 34,896 workers comprised the non-OA comparator cohort. There was a greater proportion of females in the OA cohort (55.5% vs 45.6%; P < 0.0001) and more individuals in the 40-64 year and ≥ 65 year age ranges (P < 0.0001). As OA severity increased, workers reported more frequent pain, poorer quality of life, greater use of specific healthcare resources (hospitalizations) and reduced productivity. All outcomes indicated a significantly greater burden among workers with OA relative to those without OA (P < 0.0001). Estimated total annual costs per worker were $9,801 for mild OA, $14,761 for moderate OA, $22,111 for severe OA compared with $7,901 for workers without OA (P < 0.0001). Conclusions Workers with OA were characterized by significant disease and economic burdens relative to workers without OA that substantially increased with greater self-rated OA severity. Greater levels of OA severity were associated with reductions in quality of life and productivity, and increases in healthcare resource utilization and costs.

Abstract
BACKGROUND The data available on the types of treatment delivered and healthcare costs of fibromyalgia syndrome (FMS) patients in Germany are currently not representative. MATERIAL AND METHODS The data from all 6,897,846 insured persons of the German statutory health insurance company Barmer Ersatzkasse (BEK) before the fusion with the Gmünder Ersatzkasse (GEK) were analyzed if more than 2 billing cases with the diagnosis M79.7 were found (FMS cases) in the 8 consecutive quarter years of 2007-2008. In these cases the types and costs of out-patient treatment as well as the operation and procedure key (OPS) classification of in-patient treatment in cases of any discharge diagnosis of FMS were analyzed. RESULTS A diagnosis of FMS was recorded in 14,870 insured persons in out-patient care and in 6130 in-patients from 1(st) January 2008 to 31(st) December 2009. The 1-year prevalence of FMS diagnosis was 19,592 of the patients (0.3%). Non-steroidal agents were prescribed in 48%, weak opioids in 21% and strong opioids in 11% of the out-patients with FMS. Out-patient psychotherapy was conducted in 8% of the FMS cases. In 31% of the cases hospital treatment was carried out of which 14% received multicomponent therapy. The average healthcare costs were 4,331 <euro> per year. CONCLUSION The data of the BEK document high healthcare costs and treatment which is mainly not in line with the recommendations of the German guidelines on the management of FMS.

Abstract
OBJECTIVE To assess comorbidities, pain-related pharmacotherapy, and healthcare resource use among patients with fibromyalgia (FM) newly prescribed pregabalin or duloxetine (index event) in usual care settings. METHODS Using the LifeLink™ Health Plan Claims Database, patients with FM (International Classification of Diseases, Ninth Revision, Clinical Modification code 729.1X) were identified. Patients initiated on duloxetine were propensity score-matched with patients initiated on pregabalin (n = 826; mean age [standard deviation] of 48.3 [9.3] years for both groups). Prevalence of comorbidities, pain-related pharmacotherapy, and healthcare resource use/costs were examined during the 12-month pre-index and follow-up periods. RESULTS Both patient groups had multiple comorbidities and a substantial pain-related and adjuvant medication burden. In the pregabalin group, use of other anticonvulsants decreased significantly (31.6% vs 24.9%), whereas use of serotonin-norepinephrine reuptake inhibitors (SNRIs; 16.5% vs 22.5%) and topical agents (10.1% vs 13.2%) increased in the follow-up period (p < 0.01). In the duloxetine group, there were significant decreases in the use of other SNRIs (13.0% vs 5.7%), selective serotonin reuptake inhibitors (41.3% vs 21.7%), and tricyclic antidepressants (18.8% vs 13.2%), and an increase in the use of anticonvulsants (28.6% vs 40.1%; p < 0.0001). There were significant increases (p < 0.0001) in pharmacy and total healthcare costs in both cohorts, and a significant increase in outpatient costs (p = 0.0084) in the duloxetine cohort from pre-index to follow-up. There were no significant differences in median total healthcare costs between the pregabalin and duloxetine groups in both the pre-index ($10,159 vs $9,556) and follow-up ($11,390 vs $11,746) periods. LIMITATIONS Limitations of this study are typical of those associated with retrospective database analyses. CONCLUSIONS Patients with FM prescribed pregabalin or duloxetine were characterized by a significant comorbidity and pain/adjuvant medication burden. Although healthcare costs increased in both groups, there were no statistically significant differences in direct healthcare costs between the two groups.

Abstract
OBJECTIVE To examine treatment patterns and costs among patients with fibromyalgia prescribed pregabalin or tricyclic antidepressants (TCAs). METHODS Using the LifeLink™ Health Plan Claims Database, patients with fibromyalgia (International Classification of Diseases, Ninth Revision, Clinical Modification code 729.1X) newly prescribed (index date) TCAs (n = 898) were identified and propensity score-matched (PSM) with patients newly prescribed pregabalin (n = 898). Pain-related pharmacotherapy, comorbidities, and healthcare resource use/costs were examined during the 12 months, pre-index, and follow-up periods. RESULTS Both patient groups reported multiple comorbidities and received pain medications in the pre-index and follow-up periods. Among patients prescribed pregabalin, use of non-selective non-steroidal anti-inflammatory drugs (43.3% vs 39.8%), other anticonvulsants (28.6% vs 23.3%), and tetracyclic/miscellaneous antidepressants (28.5% vs 25.8%) significantly decreased, and cyclooxygenase 2 (COX-2) inhibitors (7.7% vs 10.4%), TCAs (4.8% vs 7.9%), and topical agents (10.8% vs 15.1%) increased in the follow-up period (p < 0.05). Among patients prescribed TCAs, there were significant decreases in muscle relaxants (42.0% vs 38.4%) and sedative hypnotics (27.4% vs 23.9%), and increases in COX-2 inhibitors (5.8% vs 7.9%) and anticonvulsants (25.1% vs 33.7%; p < 0.05). There were increases (p < 0.0001) in pharmacy costs in both cohorts and total healthcare costs in the pregabalin cohort from pre-index to follow-up. Median total costs were higher (p < 0.05) in the pregabalin group vs TCAs in the pre-index ($9935 vs $8771) and follow-up ($10,689 vs $8379) periods. LIMITATIONS Despite attempts to address bias through PSM, the higher pre-index costs in the pregabalin cohort suggest a channeling of patients with more severe fibromyalgia to pregabalin. CONCLUSIONS Patients with fibromyalgia prescribed pregabalin or TCAs had multiple comorbidities and a sizeable pain medication burden, which increased in the follow-up period for both cohorts. Only 5% of pregabalin initiators had been treated with concomitant TCAs at baseline, suggesting that TCAs were inappropriate for these patients owing to their contraindications.

Abstract
OBJECTIVE To investigate the impact of musculoskeletal pain on health-related quality of life and work productivity losses among US workers. METHODS Data from the 2008 US National Health and Wellness Survey were used. Among those currently employed aged 20 to 64 years (N = 30,868), workers with arthritis (n = 2,670), back (n = 4,920), and fibromyalgia (n = 439) pain were compared with workers without those respective musculoskeletal pain conditions. RESULTS Arthritis, back, and fibromyalgia pain were all associated with significantly lower levels of health-related quality of life, often at clinically meaningful levels. All pain conditions were associated with higher levels of work productivity loss, even after adjusting for demographic and health characteristics. CONCLUSIONS Musculoskeletal pain conditions were highly prevalent and associated with a significant burden. Improved management of these conditions may lead to improved productivity, benefiting both employers and workers alike.

Abstract
OBJECTIVES The evaluation of work ability of patients with FM is difficult. Our aim was to investigate the characteristics of suitable work from the perspective of patients with FM. METHODS Interviews with patients yielded statements about characteristics of suitable work. Patients individually sorted these statements according to similarity. Hierarchical cluster analysis was applied to these sortings. RESULTS The hierarchical structure included 74 characteristics of suitable work. The 10 clusters at the lowest level included (i) recovery opportunities, (ii) pace of work, (iii) not too high workload, (iv) keeping energy for home and free time, (v) match between work and capabilities, (vi) development opportunities, (vii) understanding from colleagues, (viii) help from colleagues, (ix) support from management and (x) work agreements with management. CONCLUSIONS According to patients with FM, suitable work is paced in such a way that one can perform the job well and with satisfaction while keeping energy for home and free time and having acknowledgement and help from management and colleagues. The brief suitable work checklist that is provided can help patients with FM to negotiate with employers and job professionals to improve the match between job demands and capabilities.

Abstract
Background There has been increasing recognition that osteoarthritis (OA) affects younger individuals who are still participants in the workforce, but there are only limited data on the contribution of OA pain to work productivity and other outcomes in an employed population. This study evaluated the impact of OA pain on healthcare resource utilization, productivity and costs in employed individuals. Methods Data were derived from the 2009 National Health and Wellness Survey. Univariable and multivariable analyses were used to characterize employed individuals (full-time, part-time, or self-employed) ≥20 years of age who were diagnosed with OA and had arthritis pain in the past month relative to employed individuals not diagnosed with OA or not experiencing arthritis pain in the past month. Work productivity was assessed using the Work Productivity and Activity Impairment (WPAI) questionnaire; health status was assessed using the physical (PCS) and mental component summary (MCS) scores from the SF-12v2 Health Survey and SF-6D health utilities; and healthcare utilization was evaluated by type and number of resources within the past 6 months. Direct and indirect costs were estimated and compared between the two cohorts. Results Individuals with OA pain were less likely to be employed. Relative to workers without OA pain (n = 37,599), the OA pain cohort (n = 2,173) was significantly older (mean age 52.1 ± 11.5 years vs 41.4 ± 13.2 years; P < 0.0001) and with a greater proportion of females (58.2% vs 45.9%; P < 0.0001). OA pain resulted in greater work impairment than among workers without OA pain (34.4% versus 17.8%; P < 0.0001), and was primarily due to presenteeism (impaired activity while at work). Health status, assessed both by the SF-12v2 and the SF-6D was significantly poorer among workers with OA pain (P < 0.0001), and healthcare resource utilization was significantly higher (P < 0.0001) than workers without OA pain. Total costs were higher in the OA pain cohort ($15,047 versus $8,175; P < 0.0001), driven by indirect costs that accounted for approximately 75% of total costs. Conclusions A substantial proportion of workers suffer from OA pain. After controlling for confounders, the impact of OA pain was significant, resulting in lower productivity and higher costs.

Abstract
OBJECTIVE To compare comorbidities, drug use, benefit costs, absences, medication persistence/adherence between employees with fibromyalgia initiating treatment with pregabalin (PGB) vs. antidepressant Standard of Care ([SOC] amitriptyline, duloxetine, or venlafaxine). METHODS Retrospective study of 240 adults initiating PGB or SOC after 7/1/2007. Multivariate regression models on propensity-score-matched cohorts compared postindex costs, absences, and adherence between cohorts. RESULTS Pregabalin users had significantly more preindex muscle pain and dizziness and less depression than SOC (each P < 0.05). Use of some non-PBG/SOC drugs differed. No differences were found in total medical, drug, or absenteeism cost. PGB had more sick leave (9.8 vs. 6.8 days, P = 0.04), but other absence types were similar. All adherence metrics were nonsignificantly greater for PGB vs. SOC. CONCLUSION Despite several comorbidity and drug use differences, most employee benefit outcomes and adherence did not differ between the cohorts.

Abstract
OBJECTIVE To evaluate health care resource utilization and costs 1 year before and 3 years after a fibromyalgia (FM) diagnosis. METHODS This retrospective cohort analysis used claims from Humana to identify newly diagnosed FM patients ≥18 years of age based on ≥2 medical claims for ICD-9 CM code 729.1 and 729.0 between June 1, 2002 and March 1, 2005. Prevalence of comorbidities, as well as utilization and costs of pharmacotherapy and health care services were examined for 12 months preceding (pre-diagnosis) and 36 months following (post-diagnosis) the date of first FM diagnosis. These periods were subdivided into 6-month blocks to better observe patterns of change. RESULTS We identified 2613 FM patients who had a mean age at diagnosis of 58.5 ± 15.3 years and a mean Charlson Comorbidity Index of 0.48 ± 1.05. Of those, 73% were female. The use and costs of pain-related medications rose from pre-diagnosis and remained stable after the 6-month post-diagnosis period, while the use of non-pain-related medications steadily rose from pre-diagnosis to 3 years post-diagnosis. This increase was concomitant with an increase in the presence of conditions that may account for higher resource utilization. The use of recommended FM therapies (i.e., antidepressants and anticonvulsants) increased post-diagnosis but remained less common than other pain-related therapies. Total resource utilization and costs increased during the period up to 6 months after diagnosis. This increase was followed by a decline (7-12 months post-diagnosis), and plateau, with an increase during the final 6 months of the study period. Total mean per patient costs were $3481 for the 6-month post-diagnosis period, and $3588 for the final 6 months. Limitations include potential errors in coding and recording, and an inability of claims analyses to determine causality between resource utilization and the specific diagnosis of interest. CONCLUSIONS An FM diagnosis was associated with increased utilization and pain-related medication cost up to the first 6 months post-diagnosis followed by stabilization over 3 years post-diagnosis. Less use of recommended therapies relative to other therapies suggests that further dissemination of treatment guidelines is needed. An increase in non-pain medications over the observation period accounted for the majority of pharmacy costs. These pharmacy costs may be related to an increasing prevalence of comorbid conditions.

Abstract
OBJECTIVE To evaluate the cost effectiveness of duloxetine when considered as an alternative treatment for patients in the United States (US) being treated for fibromyalgia pain. RESEARCH DESIGN AND METHODS A Markov model was used to evaluate the economic and clinical advantages of duloxetine in controlling fibromyalgia pain symptoms over a 2-year time horizon. A base-case treatment sequence was adopted from clinical guidelines, based on tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, anticonvulsants, and opioids. Treatment response was modeled using changes from baseline in pain severity, and response thresholds: full response (at least a 50% change), response (30-49% change), and no response (less than a 30% change). Clinical efficacy and discontinuation data were taken from placebo- and active-controlled trials identified in a systematic literature review and mixed-treatment comparison. Utility data were based on EQ-5D data. MAIN OUTCOME MEASURES Additional symptom-control months (SCMs), defined as the amount of time at a response level of 30% or less, and quality-adjusted life-years (QALYs) over a 2-year time horizon. RESULTS For every 1000 patients, first-line duloxetine resulted in an additional 665 SCMs and 12.3 QALYs, at a cost of $582,911 (equivalent to incremental cost-effectiveness ratios [ICERs] of $877 per SCM and $47,560 per QALY). Second-line duloxetine resulted in an additional 460 SCMs and 8.7 QALYs, at a cost of $143,752 (equivalent to ICERs of $312 per SMC and $16,565 per QALY). LIMITATIONS Response data for TCAs are limited to 30% improvement levels, reported trials are small, and have low placebo response rates. The model necessarily assumes that response rates are independent of placement in the treatment sequence. CONCLUSIONS The results suggest that the introduction of duloxetine into the standard treatment sequence for fibromyalgia not only provides additional patient benefits, reflected by time spent in pain control, but also is cost effective when compared with commonly adopted thresholds.

Abstract
OBJECTIVE Comorbidities and resource utilization among patients with osteoarthritis (OA) in clinical practice have been infrequently characterized. The purpose of this study was to examine comorbidities, pain-related pharmacotherapy, and direct medical costs of patients with OA in clinical practice. METHOD This retrospective cohort analysis used medical and pharmacy claims data from the LifeLink™ Database. OA patients (ICD-9-CM codes 715.XX) were matched (age, gender, and region) with individuals without OA. Comorbidities, pain-related pharmacotherapy, and direct medical costs (pharmacy, outpatient, inpatient, total) were examined for the calendar year 2008. RESULTS The sample consisted of 112,951 OA patients and 112,951 controls (mean age: 56.9 [SD=9.5] years; 62% female). Relative to controls, OA patients were significantly more likely (p<0.0001) to have comorbidities, including musculoskeletal (84.3 vs. 37.1%) and neuropathic pain (22.0 vs. 6.1%) conditions, depression (12.4 vs. 6.4%), anxiety (6.6 vs. 3.5%), and sleep disorders (11.9 vs. 4.2%). OA patients were significantly more likely (p<0.0001) to receive pain-related medications, including opioids (40.7 vs. 17.1%), NSAIDs (37.1 vs. 11.5%), tramadol (9.8 vs. 1.8%), and adjunctive medications for treating depression, anxiety, and insomnia. Mean [SD] total direct medical costs were more than two times higher among OA patients ($12,905 [$21,884] vs. $5099 [$13,855]; p<0.001) and median costs were more than three times higher ($6188 vs. $1879; p<0.0001). Study limitations include potential errors in coding and recording; overestimation of the comorbidity burden; inability to link condition of interest, OA, with prescribed medications; and possible underestimation of the true costs of OA, because indirect costs were not considered and the direct costs were from a third party payer (commercial insurance) perspective. CONCLUSION The patient burden of OA was characterized by a high prevalence of comorbidities. The payer burden was also substantial, with significantly greater use of pain-related and adjunctive medications, and higher direct medical costs.

Abstract
OBJECTIVE To evaluate changes in health-care resource use and costs after initiating pregabalin or duloxetine in employees with fibromyalgia (FM). METHODS Employees (18 to 64 years old) with at least one claim for an FM-attributable medication within 60 days following an FM diagnosis were identified using the Thomson Reuters MarketScan(®) Commercial Database (2006 to 2008). Patients newly initiated on pregabalin were propensity score matched to patients newly initiated on duloxetine. These treatment cohorts were evaluated for changes between the 6-month pre- and post-initiation periods in health-care utilization including prescriptions, imputed medically related work loss and expenditures. Pre- to post-initiation changes were compared between pregabalin and duloxetine using a difference-in-difference approach based on univariate statistics and multivariable models. RESULTS A total of 731 employees with FM initiated on pregabalin (89.9% female, mean age 47.1±9.7 years) were matched with 731 employees initiated on duloxetine (89.5% female, mean age 47.1±9.8 years); other demographic and clinical characteristics were also comparable between cohorts. The adjusted marginal effects were not statistically significant for pre- to post-changes in opioid utilization (P=0.856), number of FM-attributable (P=0.151) or FM-related medications (P=0.462), and all-cause (P=0.323) or FM-attributable (P=0.991) expenditures. Pregabalin was associated with a significantly lower probability of any medically related work loss of 3.2 percentage points (P=0.030) compared with duloxetine, but changes in indirect costs were not significantly different (P=0.600). CONCLUSIONS The changes in health resource utilization and costs after initiation of pregabalin were not significantly different than the changes observed after initiation of duloxetine. These results not only demonstrate an overall similarity of resource utilization, but also suggest cost neutrality between pregabalin and duloxetine.
