Health-related quality of life and its determinants in patients with chronic low back pain at a tertiary hospital in Cameroon: a cross-sectional study

Health-Related Quality of Life in Chronic Pain Treated With Tapentadol Versus Oxycodone/Naloxone and Its Determinants: A Real-World, Single-Center Retrospective Cohort Study in Spain

OBJECTIVES

A substantial proportion of patients with chronic noncancer pain (CNCP) are treated with tapentadol (TAP) or oxycodone/naloxone (OXN) to improve their perceived physical and mental health over time.

METHODS

A cross-sectional study was conducted in 135 CNCP outpatients with usual prescribing (TAP: n = 58, OXN: n = 77) at a tertiary-care Spanish Hospital to compare health-related quality-of-life (HRQoL) records. Health utility was derived from the EQ-5D-3L. Regression models were performed to search for other HRQoL determinants. Pain intensity, relief, analgesic prescription, adverse events, inpatient stays, emergency department visits, and change to painkiller prescriptions were registered from electronic records.

RESULTS

Health utility (0.43 ± 0.24 scores, from -0.654 to 1) was similar for both opioids, although TAP showed a significantly low daily opioid dose requirement, neuromodulators use, and constipation side effect compared with OXN. After multivariable adjustment, the significant predictors of impaired HRQoL were pain intensity (β = -0.227, 95% CI -0-035 to -0.005), number of adverse events (β = -0.201, 95% CI -0.024 to -0.004), and opioid daily dose (β = -0.175, 95% CI -0.097 to -0.012). Male sex (β = -0.044) and pain relief (β = 0.158) should be taken into account for future studies.

CONCLUSIONS

HRQoL was similar for TAP and OXN in real-world patients with CNCP, albeit with a TAP opioid-sparing effect. More work is needed to explore HRQoL determinants in relation to long-term opioid use in CNCP.

Influence of Physical Activity, Physical Fitness, Age, Biological Maturity and Anthropometric Variables on the Probability of Suffering Lumbar, Neck and Shoulder Pain in Spanish Adolescents from the Region of Murcia

Background: Back pain in adolescents is a common injury, mainly affecting the lumbar, cervical and sometimes shoulder region. This has been related to various factors, such as lifestyle habits or physical capacity, but no previous research has shown conclusive results. The aims of this study was to analyze the risk of suffering lumbar, neck and shoulder pain according to anthropometric and physical fitness variables, physical activity level, age and biological maturity in adolescents, as well as the influence of sex in the study results. Methods: A descriptive cross-sectional study was performed, including a sample of 2015 adolescents (boys: n = 1006, mean age = 14.41 ± 1.35 years-old; girls: n = 1009, mean age = 14.48 ± 1.41 years-old). The participants underwent an anthropometric evaluation and physical fitness tests were carried out, including a 20 m shuttle run, a counter movement jump, a horizontal jump, a 20 m sprint and push-up tests, followed by the completion of lumbar, neck and shoulder pain questionnaires. Results: Higher values in age and peak height velocity (PHV) showed an increase in the risk of suffering lumbar, neck and shoulder pain (OR = 0.79-1.55; p = 0.000-0.025). The anthropometric variables related to adiposity showed an increase in the risk of suffering back pain, with significant incidence in the lumbar region (OR = 1.32-1.60; p = 0.000); while muscle mass showed a protective effect (OR = 0.59; p = 0.000). Regarding the fitness tests, a better physical fitness seemed to protect adolescents from suffering from the analyzed back pains in the general sample and in the boys sample (OR = 0.56-1.60; p = 0.000), while in the girls sample the influence of the physical fitness was less relevant. Conclusions: Both anthropometry and physical fitness may influence the occurrence of back pain in adolescents, with some variations in their importance according to sex.

Quality of Life in Patients with Chronic Low Back Pain and Differences by Sex: A Longitudinal Study

BACKGROUND

The experience of chronic low back pain has a significant impact on the quality of life of affected people, resulting in difficulties in performing basic activities of daily living.

AIM

To study the perceived quality of life of people affected by chronic low back pain and the associated factors by sex.

METHODS

A prospective, longitudinal and observational design was used.

RESULTS

A total of 129 people (58.1% women) with chronic low back pain were studied. The mean pain intensity scores were of moderate severity (6.42 points), with a modest improvement at follow-up (6.17 points). Epidural nerve blocks were the most effective therapeutic intervention in reducing the intensity of pain. Participants described a negative perception of their health with regard to quality of life, with low scores for the two constructs both at baseline (health index, 0.444; perception of health, 38.76 points) and at follow-up (health index, 0.447; perception of health, 40.43 points). Participants had severe functional limitation scores (50.79 points). The results were significantly better among men. There was an inverse relationship between the average pain intensity (β = -0.304; p < 0.001), functional limitation (β = -0.466; p < 0.001) and mental health (β = -0.565; p < 0.001) and quality of life.

CONCLUSIONS

The chronification of low back pain complicates people's biopsychosocial adaptation to life. There is a longitudinal inverse association between pain and functional limitation and health-related quality of life.

Fear-Avoidance Beliefs Associated with Non-Specific Chronic Low Back Pain in College Athletes

Purpose

This study aimed to determine the psychosocial factors associated with non-specific chronic low back pain (NS-CLBP) among college athletes.

Material and Methods

A cross-sectional study was performed at one university. A non-anonymous, self-administered online questionnaire was collected from each athlete. Participants with a history of orthopaedic spine disease or surgery were excluded. Online responses from 368 college athletes belonging to 18 clubs were collected, among which 263 were included in the analysis. In the 263 responses, 41 individuals were identified as having NS-CLBP. Multivariate logistic regression analyses were performed to determine factors associated with presence of NS-CLBP. Independent variables included the Fear-Avoidance Beliefs Questionnaire physical activity subscale (FABQ-PA) score, Tampa Scale for Kinesiophobia-11 (TSK-11) score, Roland-Morris Disability Questionnaire (RDQ) score, and body mass index (BMI). Additionally, the Mann-Whitney U-test was utilized to compare FABQ-PA, TSK-11, RDQ scores, and BMI between the NS-CLBP and non-NS-CLBP groups.

Results

The FABQ-PA (odd ratio = 1.096, P = 0.003) was significantly associated with NS-CLBP. No significant association was observed between NS-CLBP and TSK-11 (P = 0.776), RDQ (P = 0.074), and BMI (P = 0.296). The scores for FABQ-PA, TSK-11, RDQ, and BMI in the group with NS-CLBP were found to be significantly higher compared to the group without NS-CLBP (P < 0.001, P = 0.034, P < 0.001, and P = 0.022, respectively).

Conclusion

The present study revealed a significant relationship between higher FABQ-PA scores and NS-CLBP among college athletes. Conversely, TSK-11 and BMI values showed no significant association with NS-CLBP presence. The findings suggest that addressing fear-avoidance beliefs may be crucial in managing NS-CLBP among college athletes.

The Uptake of the Core Outcome Set for Non-Specific Low Back Pain Clinical Trials is Poor: A Meta-Epidemiological Study of Trial Registrations

We conducted a meta-epidemiological study on all non-specific low back pain (NSLBP) trial registrations on the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov. We aimed to 1) assess the uptake of the core outcome set (COS) for NSLBP in clinical trials; 2) assess the uptake of the core outcome measurement set for NSLBP in clinical trials; and 3) determine whether specific study characteristics are associated with the COS uptake. After applying the relevant filters for the condition, study type, and phase of the trial, 240 registry entries were included in this study. Only 50 (20.8%) entries showed a full COS uptake, and this rate did not increase over time. Most registry entries that planned to measure physical functioning (n = 152) used the Roland-Morris Disability Questionnaire (n = 74; 48.7%); a small percentage used the numeric rating scale (n = 60; 27.3%) or Short Form-12 (n = 5; 8.3%) if they planned to measure pain intensity (n = 220) or health-related quality of life (n = 60), respectively. Only the planned sample size (OR = 1.02; 95% CI = 1.01, 1.03) showed a significant but small association with COS uptake. The uptake of the COS for NSLBP is poor. Only 21% of the randomized controlled trials aimed to measure all COS domains in their study registration and COS uptake is not increased over time. Great heterogeneity in measurement instruments was also observed, revealing poor core outcome measurement set uptake. PERSPECTIVE: The Core Outcome Set (COS) for non-specific low back pain was published more than 20 years ago. We evaluated whether trial registrations are using this set of outcomes when testing interventions for low back pain. Full uptake was found only in 21% of the sample, and this is not increasing over time. Researchers should use the COS to ensure that trials measure relevant outcomes consistently.

Patient enablement and health-related quality of life for patients with chronic back and knee pain: a cross-sectional study in primary care

BACKGROUND

Chronic back and knee pain impairs health- related quality of life (HRQoL) and patient enablement can improve HRQoL.

AIM

To determine whether enablement was a moderator of the effect of chronic back and knee pain on HRQoL.

DESIGN AND SETTING

A cross-sectional study of Chinese patients with chronic back and knee problems in public primary care clinics in Hong Kong.

METHOD

Each participant completed the Chinese Patient Enablement Instrument-2 (PEI-2), the Chinese Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Pain Rating Scale (PRS). Multivariable regression examined the effects of PRS score and PEI-2 score on WOMAC total score. A moderation regression model and simple slope analysis were used to evaluate whether the interaction between enablement (PEI-2) and pain (PRS) had a significant effect on HRQoL (WOMAC).

RESULTS

Valid patient-reported outcome data from 1306 participants were analysed. PRS score was associated with WOMAC total score (β = 0.326, P<0.001), whereas PEI-2 score was associated inversely with WOMAC total score (β = -0.260, P<0.001) and PRS score. The effect of the interaction between PRS and PEI-2 (PRS × PEI-2) scores on WOMAC total score was significant (β = -0.191, P<0.001) suggesting PEI-2 was a moderator. Simple slope analyses showed that the relationship between PRS and WOMAC was stronger for participants with a low level of PEI-2 (gradient 3.056) than for those with a high level of PEI-2 (gradient 1.746).

CONCLUSION

Patient enablement moderated the impact of pain on HRQoL. A higher level of enablement can lessen impairment in HRQoL associated with chronic back and knee pain.

Chronic Low Back Pain: Prevalence, Impact on Quality of Life, and Predictors of Future Disability

BACKGROUND

In primary healthcare settings, chronic low back pain (cLBP) is a widespread health issue with a great global impact.

METHODS

A cross-sectional analytical study was performed on 918 adults attending primary healthcare settings in Makkah, Saudi Arabia, to estimate the cLBP prevalence, its effect on health-related quality of life (QOL), and predictors of subsequent disability. The visual analog scale of pain (VAS), World Health Organization Quality of Life Scale (WHO-QOL), and Oswestry low back pain disability index (ODI) were used to assess back pain severity, impact on QOL, and physical disability, respectively.

RESULTS

The prevalence of cLBP among adults attending primary care settings in Makkah City was 25.9%, and 88.6% of them had a limited range of motion of the spine. About 58.1% had abnormal radiological findings detected by MRI. Based on the VAS scale, most patients (83.8%) had mild pain. The median (IQR) QOL score was 70 (60-80). Minimal and moderate disability scores were prevalent among 16.2% and 65.7% of patients, respectively. Disability scores were independently predicted by a lower QOL score (beta = -0.39, 95%CI = -0.49 to -0.29, p < 0.001) and higher VAS scores (beta = 0.47, 95%CI = 0.38-0.56, p < 0.001). Furthermore, disability was independently associated with having post-void residual volume (PVRV) (beta = 5.84, 95%CI = 1.97-9.72, p = 0.004) and abnormal X-ray findings (beta = 7.10, 95%CI = 1.77-12.4, p = 0.010).

CONCLUSION

cLBP is common among adults attending primary care settings in Makkah City; it is associated with moderate disability and lower health-related QOL.

Burden of disease and impact on quality of life in chronic back pain - a comparative cross-sectional study of 150 axial spondyloarthritis and 150 orthopedic back pain patients

Objective

Chronic back pain (CBP) constitutes one of the most common complaints in primary care and a leading cause of disability worldwide. CBP may be of mechanical or inflammatory character and may lead to functional impairment and reduced quality of life. In this study, we aimed to assess and compare burden of disease, functional capacity, quality of life and depressive symptoms in axial spondyloarthritis (axSpA) patients with orthopedic chronic back pain patients (OBP). We further aimed to identify factors associated with quality of life.

Methods

Cross-sectional survey of a cohort of 300 CBP patients including 150 patients from a University Hospital Orthopedic Back Pain Outpatient Clinic with OBP and 150 patients with confirmed axSpA from a University Hospital Rheumatology Outpatient Clinic. Questionnaire-based assessment of pain character (Inflammatory Back Pain, MAIL-Scale), functional status (FFbH, BASFI), quality of life (WHOQOL-Bref) and depressive symptoms (Phq9) and retrospective medical chart analysis.

Results

Both, OBP and axSpA patients reported on average intermediate pain levels of mostly mixed pain character. Both groups demonstrated a reduced health-related quality of life and the presence of depressive symptoms. However, axSpA patients reported a significantly better subjective quality of life, more satisfaction with their health status and better functional capacity compared to OBP patients (all p < 0.001). In a multivariate regression model, depressive symptoms, mechanical back pain, pain level and age were negative predictors of subjective quality of life, whereas functional capacity was a positive predictor.

Conclusion

Chronic back pain was associated with a high morbidity and reduced quality of life regardless of pain character. We identified multiple factors associated with reduced quality of life. Awareness and addressing of these factors may help to overcome unmet needs and improve quality of life for these patients.

The Impact of Low Back Pain on the Quality of Life of Children between 6 and 12 Years of Age

This study aimed to evaluate the impact of low back pain on the perceived health-related quality of life of children between 6 and 12 years of age. This is a cross-sectional study of three hundred seventy-seven students from three schools (two private and one public) located in the city of Botucatu, São Paulo. Data were collected using the Pediatric Quality of Life Inventory (PedsQL, version 4.0), a questionnaire comprising questions on personal background, sociodemographic and socioeconomic information, and a questionnaire about quality of life. Comparisons were made between groups with and without low back pain. The chi-squared test was used for analyzing categorical variables, and the non-parametric Mann–Whitney test was used for continuous variables. According to the findings obtained in this study, it was observed that low back pain in the last month was reported by 27.3% of the total participants. The perceived health-related quality of life was lower among individuals who had low back pain, and the scores of physical and emotional functioning domains were also lower in the presence of low back pain. The prevalence of low back pain among children and adolescents is relatively high. Furthermore, the repercussions of low back pain may lead to a lower overall perception of the health-related quality of life in this population and affect aspects of physical and emotional functioning.

Health-related quality of life among spondyloarthritis and chronic low back pain patients: results from a nationwide population-based survey

PURPOSE

Both spondyloarthritis and chronic low back pain (CLBP) significantly impact health-related quality of life (HRQoL). It is important to clarify whether these disorders have different impacts on the several domains of HRQoL as different mechanisms may necessitate different treatment interventions. Moreover, the factors associated with HRQoL can inform more targeted group interventions to promote HRQoL.

METHODS

We used data from EpiReumaPt, a population-based survey conducted from September 2011 to December 2013. HRQoL was assessed with EuroQoL-5-Dimensions (EQ-5D). Spondyloarthritis was diagnosed by expert opinion (rheumatologist) and predefined criteria. CLBP was diagnosed if low back pain was present on the day of the interview and persisted for > 90 days. Univariable and multivariable linear regression analyses compared HRQoL among subjects with spondyloarthritis, CLBP, and no rheumatic diseases. Multivariable linear regression analyses evaluated HRQoL factors in spondyloarthritis and CLBP subjects.

RESULTS

We included 92 spondyloarthritis patients, 1376 CLBP patients, and 679 subjects without rheumatic diseases. HRQoL was similarly affected in spondyloarthritis and CLBP (ß =  - 0.03, 95% CI [- 0.08; 0.03]) in all EQ5D dimensions. A much lower HRQoL was found in spondyloarthritis and CLBP patients compared with subjects without rheumatic diseases (ß =  - 0.14, 95% CI [- 0.19; - 0.10]; ß =  - 0.12, 95% CI [- 0.14; - 0.09], respectively). In spondyloarthritis subjects, multimorbidity and active disease were associated with worse HRQoL (ß =  - 0.18; 95% CI [- 0.24; 0.03]; ß =  - 0.13; 95% CI [- 0.29; - 0.05], respectively), and regular physical exercise was associated with better HRQoL (ß = 0.18; 95% CI [0.10; 0.30]). In CLBP subjects, multimorbidity (β =  - 0.11; 95% CI [- 0.14; - 0.08]), obesity (β =  - 0.04; 95% CI [- 0.08; - 0.01]), and low back pain intensity (β =  - 0.02; 95% CI [- 0.03; - 0.02]) were associated with worse HRQoL, and regular physical exercise (β = 0.08; 95% CI [0.05; 0.11]) was significantly associated with better HRQoL.

CONCLUSION

Spondyloarthritis and CLBP subjects reported similar levels of impairment in the mental, physical, and social domains of HRQoL. Future health plans should address modifiable factors associated with HRQoL in these conditions to achieve better outcomes.

Global perceived improvement and health-related quality of life after physical therapy in Lebanese patients with chronic non-specific low back pain

BACKGROUND

The effectiveness of physical therapy (PT) in patients with chronic non-specific low back pain (CNSLBP) is mainly evaluated through pain, disability, and health-related quality of life (HRQOL). However, recent studies have recommended the consideration of improvement from patients' perspectives.

OBJECTIVE

This study aimed to investigate the relationship between the global perception of improvement in Lebanese patients with CNSLBP who have undergone PT, the HRQOL levels, as well as pain intensity.

METHODS

132 patients with CNSLBP who have undergone PT completed a questionnaire consisting of sociodemographic and CNSLBP characteristics questions, pain intensity numeric scale (NRS), 12-Item Short-Form Health Survey (SF-12), and the Global Perceived Effect scale (GPE). Binary logistic regressions and Pearson correlation coefficient were used for analyses.

RESULTS

Global perceived improvement of PT varies according to HRQOL levels. A significant correlation was found between pain intensity after PT, perceived improvement from PT, and HRQOL. Educational level and pain irradiation have been shown to be predictive factors of perceived improvement after PT.

CONCLUSION

Pain and HRQOL are interrelated and contributed to elucidating the global perception of improvement after PT in patients with CNSLBP. The findings suggest that patients' global perception of improvement should be considered in evaluating the benefits of physical therapy in addition to pain and HRQOL.

Prevalence of and factors associated with long-term sick leave in working-age adults with chronic low back pain in Germany

OBJECTIVE

There are little data on the impact of chronic low back pain (CLBP) on long-term sick leave. Thus, the aim was to investigate the prevalence of and the factors associated with long-term sick leave in working-age adults with CLBP in Germany.

METHODS

This retrospective study included adults aged 18-65 years diagnosed for the first time with CLBP in one of 1193 general practices in Germany between 2000 and 2019. CLBP was defined as the presence of two diagnoses of low back pain with > 90 days between them. Long-term sick leave was assessed in the year following the first diagnosis of low back pain, and was defined as > 42 days of absence from work for health-related reasons. In Germany, employees on sick leave lasting > 42 days are not paid by the employer anymore but by the health insurance fund. Finally, an adjusted logistic regression model was used to assess the association between predefined variables (e.g., age, sex, and comorbidities) and long-term sick leave.

RESULTS

A total of 59,269 working-age adults were included in this study [mean (SD) age 32.8 (11.5) years; 41.4% women]. The prevalence of long-term sick leave in the sample was 49.1%. Long-term sick leave was significantly associated with young age, male sex, and several physical and psychiatric comorbidities (e.g., reaction to severe stress and adjustment disorder, gastritis and duodenitis, and depression).

CONCLUSIONS

Based on these results, public health measures are urgently needed to mitigate the deleterious effects of CLBP on work participation in Germany.

Determinants of quality of life in individuals with chronic low back pain: a systematic review

OBJECTIVE

Chronic low back pain (CLBP) is a prominent medical condition that can affect an individual at some point in their life time which could lead to poor quality of life (QOL). Low back pain has affected approximately 577 million individuals globally by 2017. The aim of the current systematic review is to synthesise the existing evidence on the factors influencing the QOL in individuals with CLBP and to identify strategies to improve their QOL.

METHOD

PubMed, ScienceDirect, PsychNet and Google Scholar were used to extract studies reporting quantitative relationships between QOL and its possible determinants in individuals having CLBP and the intervention strategies to improve QOL.

RESULTS

10,851 studies were initially identified and twenty-six studies which met the inclusion criteria were selected for the review. 21 studies reported relationship between QOL and potential determinants and five studies assessed the influence of interventions on QOL. Determinants were classified as kinesiophobia, fear avoidance belief, or pain belief; occupation-related factors; pain and disability; activity; personal factors including age, gender, employment status; and other psychological factors including anxiety, quality of sleep, and health locus of control. Intervention strategies including MBSR, Pilates method and Back School Programme improved QOL in individuals with CLBP.

CONCLUSION

Psychosocial factors as well as the physical status of the individual contributed to the QOL in individuals having CLBP.
