Patients with chronic pain: One-year follow-up of a multimodal rehabilitation programme at a pain clinic

Healthcare-related factors influencing symptom persistence, deterioration, or improvement in patients with persistent somatic symptoms: A scoping review of European studies

OBJECTIVE

This scoping review explored healthcare-related factors associated with symptom persistence, deterioration, or improvement in patients with persistent somatic symptoms (PSS) across Europe.

METHODS

Articles were systematically searched in PubMed, Web of Science, Cochrane Library, and PsycINFO by combining terms of PSS and healthcare-related factors. Studies published in English, German, Polish, or Dutch between 2000 and 2022 were included. Healthcare-related factors associated with PSS symptom course were investigated, and study quality assessed (Center for Evidence-Based Medicine Checklist, Newcastle-Ottawa Scale).

RESULTS

Of 8386 identified studies, 56 were included in the analysis. A significant knowledge gap was evident, as most studies lacked comprehensive healthcare descriptions with particularly unclear definitions of "treatments as usual" in RCTs. The only extractable healthcare factor according to Andersen's Behavioral Model was the treatment setting. Rates of PSS improvement split by care-levels were 38% in primary, 44% in secondary, 25% in mixed, and 71% in specialized care. Persistence rates were 57%, 50%, 75%, and 29% respectively. Deterioration was observed in 5% of primary and 6% of secondary care studies. Studies were skewed toward the United Kingdom, Germany, and the Netherlands.

CONCLUSIONS

This scoping review shed light on the association between care levels and symptom outcomes in PSS patients. However, limited information in the current studies constrained our exploration of associations with other factors and symptom outcomes. Important aspects, like care availability, referral processes, and insurance coverage, are yet to be elucidated. Addressing these gaps is pivotal for developing targeted treatments across Europe, ultimately enhancing PSS patients' outcomes.

Change over time in functional capacity and self-perceived health status for patients with chronic musculoskeletal pain: a registry-based longitudinal study

BACKGROUND AND AIMS

Chronic musculoskeletal pain is a major public health problem worldwide. Both self-reported functional capacity and self-perceived health status are reduced in patients with chronic musculoskeletal pain. Previous studies mostly assessed functional capacity through self-reported questionnaires instead of objective measurements. The aim of this study, therefore, is to assess the amount of change over time and its clinical meaningfulness in functional capacity and self-perceived health status of patients with chronic musculoskeletal pain undergoing Bern Ambulatory Interprofessional Rehabilitation (BAI-Reha).

METHODS

The registry-based longitudinal cohort study with prospectively collected data from a rehabilitation programme took place in a real-life setting. Patients (n = 81) with chronic musculoskeletal pain took part in the BAI-Reha. The main outcomes were the six-minute-walk test (6MWT), the safe maximum floor-to-waist lift (SML) and the European Quality of Life and Health measure visual analogue scale (EQ VAS). Timepoints of measurement were at baseline and post-BAI-Reha (i.e., at 4 months). The quantity of interest was the adjusted time effect (point estimate, 95% confidence interval, and p-value for testing the null hypothesis of no change over time). Statistical significance (α = 0.05) and clinical meaningfulness of the mean value change over time were assessed using predefined thresholds (six-minute-walk test 50 m, SML 7 kg, and EQ VAS 10 points).

RESULTS

The linear mixed model analysis showed a statistically significant change over time for the six-minute-walk test (mean value change 56.08 m, 95% CI [36.13, 76.03]; p <0.001), SML (mean value change 3.92 kg, 95% CI [2.66, 5.19]; p <0.001), and EQ VAS (mean value change 9.58 points, 95% CI [4.87, 14.28]; p <0.001). Moreover, the improvement in the six-minute-walk test is clinically meaningful (mean value change 56.08 m) and almost clinically meaningful (mean value change 9.58 points) in the EQ VAS.

CONCLUSION

Patients walk further, lift more weight, and feel healthier after interprofessional rehabilitation when compared to baseline measurement. These findings confirm and add to previous results.

IMPLICATIONS

We encourage other providers of rehabilitation for patients with chronic musculoskeletal pain to measure functional capacity with objective outcome variables and to use self-reported outcome measures in addition to self-perceived health status. The well-established assessments used in this study are suitable for this purpose.

Association between sense of coherence and depression in patients with chronic pain: A systematic review and meta-analysis

BACKGROUND

Chronic pain is a common complaint having distressing consequences for those that suffer from it. Pain and depression concur within the context of comorbidity, and both share underlying stress conditions. Sense of coherence (SOC) is a factor that determines how well an individual manages stress and stays healthy. Its relationship with depression has been frequently reported in the literature. Our objective was to assess the amount of evidence available regarding the association between SOC and depression in patients suffering from chronic pain.

METHODS

A systematic review and meta-analysis were performed. Searches were conducted between November 01 and December 31, 2020 in PubMed, Web of Science, Embase, PsycINFO, Psicodoc, ScienceDirect and Dialnet. There were no restrictions regarding the date of publication of the study. Evidence related to the relationship between SOC and depression in patients with chronic pain was summarized and compared.

RESULTS

A total of 163 articles were identified. We included 9 papers in the qualitative and quantitative synthesis. The pooled correlation coefficient was -0.55 (95%: -0.70; -0.41) and was not modified after removing any study. The heterogeneity across the studies was considerable (I2 = 94.8%; p < 0.001). The random-effects meta-regression models for the association between SOC and depression showed that age (p = 0.148) and percentage of women (p = 0.307) were not related to heterogeneity across studies. No publication bias was detected (p = 0.720).

CONCLUSIONS

At first glance, the included studies give the impression that SOC is an important factor in depression levels of patients with chronic pain. Most of the included studies revealed a moderate association between SOC and depressive symptoms.

Longitudinal outcome evaluations of Interdisciplinary Multimodal Pain Treatment programmes for patients with chronic primary musculoskeletal pain: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVES

Although Interdisciplinary Multimodal Pain Treatment (IMPT) programmes share a biopsychosocial approach to increase the wellbeing of patients with chronic pain, substantial variation in content and duration have been reported. In addition, it is unclear to what extent any favourable health outcomes are maintained over time. Therefore, our first aim was to identify and analyse the change over time of patient-related outcome measures in cohorts of patients who participated in IMPT programmes. Our second aim was to acquire insight into the heterogeneity of IMPT programmes.

DATABASES AND DATA TREATMENT

The study protocol was registered in Prospero under CRD42018076093. We searched Medline, Embase, PsycInfo and Cinahl from inception to May 2020. All study selection, data extraction and risk of bias assessments were independently performed by two researchers. Study cohorts were eligible if they included adult patients with chronic primary musculoskeletal pain for at least 3 months. We assessed the change over time, by calculating pre-post, post-follow-up and pre-follow-up contrasts for seven different patient-reported outcome domains. To explore the variability between the IMPT programmes, we summarized the patient characteristics and treatment programmes using the intervention description and replication checklist.

RESULTS

The majority of the 72 included patient cohorts significantly improved during treatment. Importantly, this improvement was generally maintained at follow-up. In line with our expectations and with previous studies, we observed substantial methodological and statistical heterogeneity.

CONCLUSIONS

This study shows that participation in an IMPT programme is associated with considerable improvements in wellbeing that are generally maintained at follow-up. The current study also found substantial heterogeneity in dose and treatment content, which suggests different viewpoints on how to optimally design an IMPT programme.

SIGNIFICANCE

The current study provides insight into the different existing approaches regarding the dose and content of IMPT programs. This analysis contributes to an increased understanding of the various approaches by which a biopsychosocial perspective on chronic pain can be translated to treatment programs. Furthermore, despite theoretical and empirical assertions regarding the difficulty to maintain newly learned health behaviors over time, the longitudinal analysis of health outcomes did not find a relapse pattern for patients who participated in IMPT programs.

Maintenance of quality of life improvement for patients with chronic pain and obesity after interdisciplinary multimodal pain rehabilitation - A study using the Swedish Quality Registry for Pain Rehabilitation

BACKGROUND

Throughout the world many people have both obesity and chronic pain, comorbidities that decrease Health-Related Quality of Life (HRQoL). It is uncertain whether patients with comorbid obesity can maintain improved HRQoL after Interdisciplinary Multimodal Pain Rehabilitation (IMMPR).

METHODS

Data from 2016, 2017, and 2018 were obtained from a national pain database for Swedish specialized pain clinics and collected at three time points: Pre-IMMPR; Post- IMMPR; and 12-month follow-up (FU-IMMPR). Participants (N = 872) reported body weight, height, pain aspects, and HRQoL (RAND 36-Item Health Survey). Severe obesity (Body Mass Index, BMI ≥35 kg/m² ) was defined according to WHO classifications. We used linear mixed regression models to examine BMI group differences in HRQoL over time.

RESULTS

More than 25% of patients (224/872) were obese and nearly 30% (63/224) of these were severely obese. All BMI groups improved significantly in both physical and mental composites of HRQoL after IMMPR (Pre- vs. Post-IMMPR, p < .001). The improvements were maintained at a 12-month follow-up (Post- vs. FU-IMMPR, p > .05). The severe obesity group had the lowest physical health score and least improvement (pre- vs. FU-IMMPR, Cohen's d = o.422, small effect size). Severe obesity had negative impact on physical health (β = -4.39, p < .05) after controlling for sociodemographic factors and pain aspects.

CONCLUSION

Improvements in HRQoL after IMMPR were achieved and maintained across all weights, including patients with comorbid obesity. Only severe obesity was negatively associated with physical health aspects of HRQoL.

SIGNIFICANCE

Patients with chronic pain and comorbid obesity achieve sustained Health-Related Quality of Life (HRQoL) improvements from Interdisciplinary Multimodal Pain Rehabilitation (IMMPR). This finding suggests that rehabilitation professionals should consider using IMMPR for patients with comorbid obesity even though their improvement may not reach the same level as for non-obese patients.

Is the word "osteoporosis" a reason for kinesiophobia?

BACKGROUND

Osteoporosis is a systemic skeletal disease that causes weakening of the bones which increases the risk of fractures. Especially hip fractures lead to substantial physical, psychological, social and economic burden both for the patients and the governments. Exercises and physically active life style are essential preventive and therapeutic approaches for osteoporosis. Kinesiophobia is an irrational fear of movement due to the belief of susceptibility to injury. It is associated with lower levels of physical activity. Having a diagnosis of osteoporosis without an adequate education about the disease may lead to kinesiophobia in patients due to an illogical belief about increasing possibility of falls and related fractures during physical activity.

AIM

To evaluate relationship between the diagnosis of osteoporosis and kinesiophobia.

DESIGN

Case-control study.

SETTING

Division of Rheumatology, Department of Rehabilitation, University Hospital.

POPULATION

Fifty-four subjects with osteoporosis and fifty-four healthy subjects who were age- and gender-matched.

METHODS

Demographic data of subjects (age, gender, weight, height, body mass index, disease duration) were recorded. The Tampa Kinesiophobia Scale (TKS) was applied to determine the level of fear of movement. Hospital Anxiety and Depression Scale (HADS) was used to evaluate mood status. The Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) was performed to assess health related quality of life. Scores were compared between groups by Mann Whitney U test. Correlation between kinesiophobia and QUALEFFO-41 scores was performed by Spearman rank correlation.

RESULTS

Subjects with osteoporosis had higher level of kinesiophobia than healthy control subjects. There was no significant difference in HADS scores between the groups. QUALEFFO-41 total score was worse in subjects with osteoporosis than those in healthy subjects. There was a significant correlation between QUALEFFO-41 total score and kinesiophobia score in subjects with osteoporosis.

CONCLUSIONS

Subjects with osteoporosis have higher levels of kinesiophobia compared to age and gender-matched healthy subjects. Kinesiophobia may affect the quality of life in subjects with osteoporosis.

CLINICAL REHABILITATION IMPACT

As physical activity is essential for bone and general health, individuals should be educated and counseled about osteoporosis and the importance of physical activity to overcome kinesiophobia.

Assessment and treatment at a pain clinic: A one-year follow-up of patients with chronic pain

BACKGROUND AND AIMS

Pain is one of the most common reasons for patients to seek primary health care. Pain relief is likely to be achieved for patients suffering from acute pain, but for individuals with chronic pain it is more likely that the condition will persist. These patients have the option of being referred to specialised pain clinics. However, the complexity surrounding chronic pain patients is not well studied in these settings. This study aimed to describe patients with chronic pain referred to a pain clinic by using the information submitted during their first visit and one year later and also to identify associations between baseline characteristics and improvements in health-related quality of life in the follow-up.

METHODS

This was a longitudinal observational study of a sample consisting of 318 patients referred to a pain clinic. One group of patients containing 271 individuals (median age 48, 64% females) was assessed and received conventional pain treatment (CPT group) and a second group of 47 patients (median age 53, 64% females) was assessed by a pain specialist and referred back to their physician with a treatment recommendation (assessment only, AO group). Patient-reported outcome measures in health-related quality of life (EQ-5D), pain intensity (VAS), mental health (HADS), insomnia (ISI), pain-related disability (PDI), kinesiophobia (TSK) and sense of coherence (SOC) were collected at the first visit and one year later.

RESULTS

At baseline, the CPT group reported a low EQ-5D Index (median (md) 0.157) and EQ VAS (md 40) as well as considerable high, current pain intensity VAS (md 58), HADS anxiety (md 8), ISI (md 17), PDI (md 36) and TSK (md 39). The AO group showed similar problems (no significant differences compared to the CPT group), except for ISI, where the AO group reported less severe problems. At the one-year follow-up, the CPT group had a statistically significant improvement in EQ-5D, VAS, ISI, PDI and TSK. In the AO group no significant changes were observed. In the CPT group there was an association between a high ISI level at baseline and an improved EQ-5D Index in the follow-up.

CONCLUSIONS

The study describes rarely explored groups of patients with chronic pain at a pain clinic. Severe pain problems were present in both groups at their first visit. A statistically significant improvement could be seen in the group that was conventionally treated while this was not the case among those subjects who were assessed and referred. The results imply, that relatively limited treatment strategies were helpful for the patients' health-related quality of life. Despite these improvements, the patients were not fully recovered, pointing to the chronicity of pain conditions and the need of support for many patients.

IMPLICATIONS

Increased knowledge about assessment, selection and treatment at pain clinics is important to improve the quality of the work performed at these clinics. Despite limited resources, further efforts should be made to collect comparable, valid data on a regular base from pain clinics in order to develop recommendation models.
