Abstract
Chronic opioid prescribing (COP) for noncancer pain is highly restricted in Taiwan, but tramadol is not listed in the regulation on chronic prescribing. This study investigated the trajectories of COP in noncancer pain when considering tramadol in Taiwan and identified the risk of serious adverse events. This population-wide longitudinal cohort study used the Taiwan National Health Insurance claims records from 2001 to 2016. Adults prescribed opioids (including tramadol) and without cancer were selected. Patients who received COP (opioid supply days for 28 days or continuous opioid supply for 14 days) in the first patient quarter were included, and serious adverse events were identified. Group-based trajectory models were applied to identify patients with a similar trajectory of quarterly COP. The Cox proportional hazard model was applied to assess the association between adverse events and patients' trajectories. Of the 2,360,358 noncancer opioid users, 476,934 (20.2%) received COP in the first quarter. Four groups of COP trajectory were identified, and 59,310 (12.8%) patients received COP quarterly over 2 years. Patients categorized into the trajectory of long-term COP had a significantly higher crude incidence rate of cardiovascular death, seizure, and hypoglycemia. Still, there is no newly developed opioid use disorder. There was a substantial underestimate in COP in Taiwan when tramadol was not considered. Notably, 10% of them could receive COP for over 2 years. The result raises concern about unmet pain management needs and the limited accessibility of alternative treatments for noncancer pain.

Can Baseline Characteristics Predict Successful Outcomes after Individual, Physiotherapist-Led Rehabilitation in Patients with Chronic Musculoskeletal Pain? Pain Res Manag 2023; 2023:5182996. [PMID: 37360748 PMCID: PMC10289872 DOI: 10.1155/2023/5182996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 05/24/2023] [Accepted: 06/02/2023] [Indexed: 06/28/2023]
Abstract
Background No strong and consistent variables to predict outcome after pain rehabilitation have been reported in patients with chronic musculoskeletal pain. The aim of the present study was to clarify if baseline variables could predict successful outcome after a unique, individualized, physiotherapist-led rehabilitation of nine sessions. Methods In 274 individuals with severe chronic musculoskeletal pain, the risk ratio (RR) and 95% confidence intervals (CIs) were estimated for potentially predictive baseline variables on successful outcomes of pain management, overall health, and pain rating. Results Statistically significant results show that patients rating moderate or severe baseline pain were in both cases 14% less likely to improve pain management compared to patients rating mild baseline pain (RR = 0.86; 95% CI 0.77-0.97, RR = 0.86; 95% CI 0.74-1.00). Patients with the shortest pain duration were 1.61 times more likely to improve overall health (RR = 1.61; 95% CI 1.13-2.29) compared to patients reporting the longest pain duration (>5 years). Patients reporting anxiety/depression or severe pain were in both cases 1.48 times more likely to improve overall health compared to better baseline presentations (RR = 1.48; 95% CI 1.16-1.88, RR = 1.48; 95% CI 1.03-2.15). Patients with regional/generalized pain were 36% less likely to rate pain reduction (RR = 0.64; 95% CI 0.41-1.00) compared to patients rating localized baseline pain. Of 17 potentially predictive baseline variables, four reached statistical significance for at least one of the three outcomes; although none of them for all three outcomes. Conclusions Of 17 potentially predictive baseline variables, mild pain ratings, short pain duration, and localized baseline pain were statistically significantly associated with improvements after individual, physiotherapist-led rehabilitation for patients with chronic musculoskeletal pain. This suggests that this type of rehabilitation probably should be offered early in the pain process. Reporting anxiety/depression or severe pain at the baseline did not hinder the improvements of overall health.

Abstract
BACKGROUND Health-related quality of life (hrQoL) is a core outcome in evaluating interdisciplinary pain rehabilitation (IPR). This systematic review aimed to identify prognostic factors for hrQoL at least six months after IPR in chronic pain patients. METHODS A systematic search was conducted in MEDLINE, PsycINFO, EMBASE, CINAHL, Web of Science and Cochrane CENTRAL until September 2020. Included were prognostic studies on the outcome hrQoL in adults aged 18 to 67 years with chronic pain (excluding malignancies, systemic-, inflammatory or degenerative joint diseases) who had undergone IPR. Studies were assessed with The Quality in Prognostic Studies-tool. Potential prognostic factors at baseline for the domains pain, psychological and physical functioning were qualitatively synthesized for hrQoL. Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the level of evidence. RESULTS Fourteen studies on 6,668 participants (mean age 37.4-52.8 y), with musculoskeletal pain/fibromyalgia and a pain duration ranging between 13.1 and 177.4 months were considered eligible. With a very low certainty of evidence, pain intensity, emotional distress, and physical functioning at baseline were inconsistent for prediction of hrQoL and pain duration was not predictive. With low certainty of evidence, fewer pain sites, lower levels of negative cognitive behavioral factors, and higher levels of positive cognitive behavioral factors predicted a better outcome. CONCLUSIONS The overall certainty of evidence was low to very low, making it difficult to reach definitive conclusions at present. Future studies with a predefined core set of predictors investigating hrQoL in patients with chronic pain after IPR are needed.

Abstract
OBJECTIVES This systematic review aimed to identify and evaluate prognostic factors for long-term (≥6 mo) physical functioning in patients with chronic musculoskeletal pain following multidisciplinary rehabilitation (MDR). MATERIALS AND METHODS Electronic searches conducted in MEDLINE, PsycINFO, EMBASE, CINAHL, Web of Science, and Cochrane CENTRAL revealed 25 original research reports, published 1983-2016, (n=9436). Potential prognostic factors relating to initial pain and physical and psychological functioning were synthesized qualitatively and quantitatively in random effects meta-analyses. The level of evidence (LoE) was evaluated with Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS Pain-related factors (intensity and chronicity) were not associated with function/disability at long-term follow-up, odds ratio (OR)=0.84; 95% confidence interval (CI), 0.65-1.07 and OR=0.97; 95% CI, 0.93-1.00, respectively (moderate LoE). A better function at follow-up was predicted by Physical factors; higher levels of initial self-reported functioning, OR=1.07; 95% CI, 1.02-1.13 (low LoE), and Psychological factors; low initial levels of emotional distress, OR=0.77; 95% CI, 0.65-0.92, low levels of cognitive and behavioral risk factors, OR=0.85; 95% CI, 0.77-0.93 and high levels of protective cognitive and behavioral factors, OR=1.49; 95% CI, 1.17-1.90 (moderate LoE). DISCUSSION While pain intensity and long-term chronicity did not predict physical functioning in chronic pain patients after MDR, poor pretreatment physical and psychological functioning influenced the prognosis negatively. Thus, treatment should further target and optimize these modifiable factors and an increased focus on positive, psychological protective factors may perhaps provide an opening for yet untapped clinical gains.

Use of pain medication before and after inpatient musculoskeletal rehabilitation: longitudinal analysis of a nationwide cohort. Int J Rehabil Res 2017; 41:159-165.

Abstract
The objective of this study was to identify subgroups among the participants in inpatient multidisciplinary musculoskeletal rehabilitation based on the differences in the shapes of trajectories of pain medication consumption during the 9 years around the time of intervention. A register-based study among 4578 public sector employees was conducted. Group-based trajectory analysis was done on the purchase of prescribed pain medications during the 9 years around the time of rehabilitation. The participants were on an average 50.7 (SD=6.6) years of age, and 2955 (86%) were women. Average yearly purchase of pain medications increased during the follow-up period from 73.4 (SD=193.0) to 163.3 (SD=295.7) defined daily doses. The analysis suggested six-cluster model. The shapes of the trajectories of three clusters did not show any steep slopes, one trajectory demonstrated nonstop rising through the entire follow-up, and one trajectory was closed to the trajectory average of medication use. One trajectory (11% of the sample) demonstrated a steep growth before the intervention and steep drop after it. When comparing this cluster with all other clusters combined, odds ratios were 0.40 [95% confidence interval (CI): 0.19-0.85] for age group (older vs. younger), 0.78 (95% CI: 0.61-1.01) for sex (women vs. men), and 1.44 (95% CI: 1.09-1.90) for occupational status (lower vs. higher). In other words, the participants belonged to this cluster were younger employees with a lower occupational grade. It seems that younger employees in manual jobs benefitted of the studied multidisciplinary musculoskeletal rehabilitation the most, especially when the timing of intervention is bounded to the substantial rise of pain severity.

Abstract
BACKGROUND AND AIMS Multimodal rehabilitation (MMR) programmes, including, physical training, educational and psychological interventions by an interdisciplinary team are found to be more successful for patients with disabling chronic pain compared with less comprehensive treatments. MMR programmes are based on the biopsychosocial model and the goal is usually to improve function, quality of life and facilitate and enable return to work. As pain clinics traditionally offer conventional medical pain treatment, there is limited knowledge about MMR given in this context. The aim of our study was to describe characteristics of patients with chronic pain, treated with a MMR programme at a conventional pain clinic, to evaluate patient-reported outcome measures (PROM) from start to one year after, and to study possibly associated factors for the improvement of health-related quality of life after one year. METHODS A prospective, observational study with a one-year follow-up was performed. SUBJECTS A total of 42 individuals (38 females, age 44.0±12.3 years and 4 men age 40±8.5 years) with different pain diagnoses were included. After a team assessment, the patients began a programme that lasted about three months. The MMR programme contained coordinated, individually adapted treatments administered individually or in groups, and was based on cognitive behavioural principles. Questionnaires regarding health-related quality of life (HRQoL) (EQ-5D), insomnia (ISI), mental health (HADS), pain-related disability (PDI), kinesiophobia (TSK), current pain intensity (VAS) and sense of coherence (SOC) were used at the start of the MMR and at follow-up. Demographic data were collected from the patient records. RESULTS The PROM at baseline showed substantial pain problems with low HRQoL (EQ-5D index of 0.1±0.282, and EQ VAS of 32.67±20.1), moderate insomnia (ISI 18.95±6.7), doubtful cases of depression and anxiety (HADS-depression 9.35±4.1 and HADS-anxiety 9.78±3.95), presence of pain-related disability (PDI 39.48 ±12.64), kinesiophobia (TSK 40.8±9.8), as well as moderate current pain (VAS 61.31±20.4). The sense of coherence was weak (SOC of 51.37±14). At one-year follow-up, significant (p≤0.05) improvement occurred on the EQ-5D index, EQ VAS, ISI, PDI and TSK. In the logistic regression analysis, no significant associations could be identified. CONCLUSIONS MMR for patients with complex pain problems can be a successful treatment alternative at conventional pain clinics. IMPLICATIONS Since access to rehabilitation clinics in Sweden may be limited, the availability of MMR can increase by providing this type of intervention in pain clinics. Increased knowledge of MMR in different settings can also contribute to increased understanding and collaboration between pain clinics and rehabilitation units.

Abstract
PURPOSE The present study aimed to identify predictors of rehabilitation outcome for patients with chronic musculoskeletal pain (CMP) and psychological problems. METHODS A retrospective cohort study including 230 adult patients with CMP admitted for multidisciplinary pain rehabilitation. Potential predictors were patient characteristics, duration of complaints, baseline functioning, pain, personality, coping style, fear of movement, psychological distress and type of treatment. Outcome measures were physical functioning, mental health, pain and patient-reported effect. Multiple (logistic) regression models were used to identify predictors. RESULTS Patients who were more disabled and patients with more pain benefitted more from the rehabilitation treatment than less disabled patients or those with less pain. Age, work status, vitality, depression and coping style also predicted outcomes significantly. The models explained between 27 and 80% of the outcomes. There was an interaction between type of treatment, work status and the baseline pain score as regards the outcome in terms of pain. CONCLUSIONS No strong predictors of treatment outcome were found other than the baseline scores of the respective outcome variables. More disabled patients and patients with more pain benefitted more from the rehabilitation program. Other predictors improved the prediction models slightly. Implications for Rehabilitation It remains challenging to correctly predict the outcome of treatment from patients' baseline sociodemographic and psychological characteristics; predictors other than baseline scores of the outcome variables are only slightly associated with treatment outcome. Patients with chronic musculoskeletal pain and poor physical functioning or mental health benefit most from pain rehabilitation. Older patients benefit less from a pain rehabilitation program than younger patients in terms of physical functioning. Pain reduction during a pain rehabilitation program is greatest in patients with high pain intensity who are not at work at the start of the rehabilitation program. Coping style influences the outcome of rehabilitation of patients with chronic musculoskeletal pain.

Abstract
We examined the relative impact of baseline anxiety, depression and fear of movement on health related quality of life at 12-month follow-up after a multidisciplinary pain management programme. One hundred and eleven patients who had chronic musculoskeletal pain (mean age 45 years, 65% women) attended during 2003–2005 a multidisciplinary three-phase pain management programme with a total time frame of six to seven months, totalling 19 days. The Beck Anxiety Inventory was used to rate anxiety, the Beck Depression Inventory depression, the Tampa Scale of Kinesiophobia fear of movement. The generic 15D questionnaire was used to assess health related quality of life. Baseline data were collected at admission, follow-up data at 12 months. Mean health related quality of life increased significantly from baseline to 12-month follow-up. Anxiety at baseline predicted significant negative change in the health related quality of life, depression predicted significant positive change in the health related quality of life. Fear of movement did not predict any significant change in the health related quality of life. We concluded that patients with chronic musculoskeletal pain and mild to moderate depression benefit from a multidisciplinary pain management programme in contrast to anxious patients. The findings imply further research with bigger sample sizes, other than HRQoL outcome measures as well as with other groups of patients.

Abstract
BACKGROUND Long-term sick leave due to mental health problems, especially among women, is a substantial problem in many countries, and a major reason for this is thought to be psychosocial stress. The recovery period of different patient groups with stress-related mental health problems can differ considerably. We have studied the course of mental health symptoms during 18 months of multimodal treatment in relation to sex and age in a group of patients with stress-related exhaustion. METHODS The study group includes 232 patients (68% women) referred to a stress clinic and who fulfilled the criteria for Exhaustion Disorder (ED). The majority also fulfilled diagnostic criteria for depression and/or anxiety; this was similar among women and men. Symptoms were assessed at baseline, three, six, 12 and 18 months by the Shirom-Melamed Burnout Questionnaire (SMBQ) and the Hospital Anxiety and Depression scale (HAD). A total SMBQ mean score of ≥ 4 was used to indicate clinical burnout, which correlates well with the clinical diagnosis of ED. RESULTS There were no statistically significant differences between women and men or between young and old patients in the self-reported symptoms at baseline. The proportion that had high burnout scores decreased over time, but one-third still had symptoms of clinical burnout after 18 months. Symptoms indicating probable depression or anxiety (present in 34% and 65% of the patients at baseline, respectively) declined more rapidly, in most cases within the first three months, and were present only in one out of 10 after 18 months. The course of illness was not related to sex or age. The duration of symptoms before seeking health care, but not the level of education or co-morbid depression, was a predictor of recovery from symptoms of burnout after 18 months. CONCLUSIONS The course of mental illness in patients seeking specialist care for stress-related exhaustion was not related to sex or age. The burden of mental symptoms is high and similar for men and women, and at the 18 month follow-up, one-third of the study group still showed symptoms of burnout. A long duration of symptoms before consultation was associated with a prolonged time of recovery, which underlines the importance of early detection of stress-related symptoms.

Abstract
Background and methods Pain Study Tracking Ongoing Responses for a Year (PainSTORY) is a longitudinal study generating some quantitative and limited qualitative data concerning the experiences of individual patients with non-malignant chronic pain. Research was conducted across 13 European countries and a total of 294 patients completed the full evaluation process over 12 months. Adult patients (>18 years old) scoring >4 on an 11-point numeric pain rating scale (NRS-11) for most days during an average week were eligible. Four waves of interviews (W1-W4) were conducted over 12 months and information was recorded regarding pain levels, the impact of pain, pain treatment and treatment-associated side effects. Results At 3 months, 95% of respondents rated their worst pain level over the past week as ≥4. Most respondents had felt this pain level for ≥1 year, with 47% of patients reporting NRS-11 scores of 8-10 for >2 years. At 12 months, 93% of respondents still rated their worst pain level over the past week as ≥4. The overall net percentage of respondents with ≥4 pain intensity did not change substantially over 12 months of follow up. However, 40% (119/294) of patients felt their current pain level increased and 41% (121/294) felt their current pain level decreased during this time, with just 18% (53/294) of respondents reporting no change (1% of respondents not stated). At 3 months, 30% of respondents reported being managed by a pain specialist within the last 3 months, decreasing to 13% 9-12 months later. Patients were typically taking a combination of prescribed and non-prescribed medications; approximately 10% at W1 and 14% at 12 months were prescribed a strong opioid. Among those whose current pain level decreased over the year, a slightly lower proportion of patients were taking prescription medication (78%) at 12 months than in either the group with no change to their current pain level (85%), or the group whose pain level increased over the 12 month period (87%). Pain negatively affected quality of life, with respondents reporting difficulties with daily activities, including sleeping, walking, family and social interaction. Approximately half of respondents taking prescription medication reported suffering from 'constipation and associated symptoms'. In spite of no change in pain intensity, 51% of patients were happy with their pain management at W4. Conclusions The heavy individual and societal burden of uncontrolled chronic pain is demonstrated in this study. This silent epidemic has not attracted the focus of attention that it deserves. Despite the significant negative impact on individual quality of life, patients evolve to a position where they believe that chronic pain is inevitable and untreatable. implications It is clear that there is a real need for a coordinated response by healthcare providers and planners across European countries. Minimum standards of care should be developed and implemented at national level. Healthcare professionals and students of these disciplines must be educated to recognise, assess and manage pain within a reasonable timeframe. Patients who are not responding to standard measures must have rapid and easy access to a comprehensive, inter-disciplinary pain service.

Abstract
BACKGROUND Chronic pain is associated with depression. In rodents, pain is often assessed by sensory hypersensitivity, which does not sufficiently measure affective responses. Low-dose ketamine has been used to treat both pain and depression, but it is not clear whether ketamine can relieve depression associated with chronic pain and whether this antidepressant effect depends on its antinociceptive properties. METHODS The authors examined whether the spared nerve injury model of neuropathic pain induces depressive behavior in rats, using sucrose preference test and forced swim test, and tested whether a subanesthetic dose of ketamine treats spared nerve injury-induced depression. RESULTS Spared nerve injury-treated rats, compared with control rats, showed decreased sucrose preference (0.719 ± 0.068 (mean ± SEM) vs. 0.946 ± 0.010) and enhanced immobility in the forced swim test (107.3 ± 14.6s vs. 56.2 ± 12.5s). Further, sham-operated rats demonstrated depressive behaviors in the acute postoperative period (0.790 ± 0.062 on postoperative day 2). A single subanesthetic dose of ketamine (10 mg/kg) did not alter spared nerve injury-induced hypersensitivity; however, it treated spared nerve injury-associated depression-like behaviors (0.896 ± 0.020 for ketamine vs. 0.663 ± 0.080 for control rats 1 day after administration; 0.858 ± 0.017 for ketamine vs. 0.683 ± 0.077 for control rats 5 days after administration). CONCLUSIONS Chronic neuropathic pain leads to depression-like behaviors. The postoperative period also confers vulnerability to depression, possibly due to acute pain. Sucrose preference test and forced swim test may be used to compliment sensory tests for assessment of pain in animal studies. Low-dose ketamine can treat depression-like behaviors induced by chronic neuropathic pain.
