Chronic low back pain in older adults: What physicians know, what they think they know, and what they should be taught

Chronic low back pain (CLBP) is a common and debilitating problem in older adults. Little exists in the literature about primary care physicians' (PCPs') knowledge of and confidence in managing this problem. A self-administered survey was mailed to PCPs in western Pennsylvania to measure knowledge of the evaluation and treatment of common contributors to CLBP in older adults, confidence in diagnosing these contributors through physical examination, and the association between confidence levels and knowledge. The survey combined items with an ordinal scale on which PCPs ranked their confidence in detecting various contributors to CLBP (e.g., fibromyalgia) using physical examination and patient vignettes followed by multiple choice questions designed to assess knowledge. One hundred fifty-three of 634 surveys were returned (24.1%). Overall, the majority of PCPs did not feel "very confident" in their ability to diagnose any of the contributors of CLBP listed (most items <40%). PCPs felt most confident in detecting scoliosis and least confident detecting myofascial pain of the piriformis muscle. There was a wide range in the number of respondents answering all questions related to a particular topic correctly (3.9% for sacroiliac joint syndrome to 70.4% for hip osteoarthritis). There was no relationship between knowledge scores and confidence ratings (P > .05 for all comparisons). The results point to a need for more PCP education about CLBP in older adults. It also suggests that accurate needs assessment should not rely on physician confidence ratings alone.     

The prevalence of back pain in patients in one Australian tertiary hospital population

Objectives

The aims of the present study were to provide back pain (BP) point prevalence data from inpatients at an Australian tertiary hospital on one day, and compare this with Australian non‐hospitalized population prevalence data; to collect data around the development of BP throughout hospital admission; and to analyse the association between BP and past history of BP, gender, age, admission specialty and hospital length of stay (LOS).

Methods

This was a single‐site, prospective, observational study of hospitalized inpatients on one day during 2016, with a subsequent survey over the following 11 days (unless discharge or death occurred sooner).

Results

Data were collected from 343 patients (75% of the hospitalized cohort). A third of patients (n = 108) reported BP on admission, and almost a fifth (n = 63) developed new BP during their hospitalization. Patients who described BP at any time during their hospital stay had a higher chance of having had a history of BP, with odds increasing after adjustment for age and gender (odds ratio 5.89; 95% confidence interval (CI) 3.0 to 11.6; p < 0.001). After adjusting for age and gender, those experiencing BP had a significantly longer LOS (median 13 days; CI 10.8 to 15.3) than those who did not (median 10 days; CI 8.4 to 11.6; p = 0.034).

Conclusions

Hospital LOS for patients who complained of BP at any time during their admission was 3 days longer than those who had no BP, and a history of BP predicted a higher likelihood of BP during admission. Screening of patients on admission to identify any history of BP, and application of a package of care including early mobilization and analgesia may prevent the onset of BP and reduce LOS.     

Evaluating and managing acute low back pain in the primary care setting

Acute low back pain is a common reason for patient calls or visits to a primary care clinician. Despite a large differential diagnosis, the precise etiology is rarely identified, although musculoligamentous processes are usually suspected. For most patients, back symptoms are nonspecific, meaning that there is no evidence for radicular symptoms or underlying systemic disease. Because episodes of acute, nonspecific low back pain are usually self-limited, many patients treat themselves without contacting their primary care clinician. When patients do call or schedule a visit, evaluation and management by primary care clinicians is appropriate. The history and physical examination usually provide clues to the rare but potentially serious causes of low back pain, as well as to identify patients at risk for prolonged recovery. Diagnostic testing, including plain x-rays, is often unnecessary during the initial evaluation. For patients with acute, nonspecific low back pain, the primary emphasis of treatment should be conservative care, time, reassurance, and education. Current recommendations focus on activity as tolerated (though not active exercise while pain is severe) and minimal if any bed rest. Referral for physical treatments is most appropriate for patients whose symptoms are not improving over 2 to 4 weeks. Specialty referral should be considered for patients with a progressive neurologic deficit, failure of conservative therapy, or an uncertain or serious diagnosis. The prognosis for most patients is good, although recurrence is common. Thus, educating patients about the natural history of acute low back pain and how to prevent future episodes can help ensure reasonable expectations.     

Efficacy of percutaneous electrical nerve stimulation for the treatment of chronic low back pain in older adults

OBJECTIVES: To determine the efficacy of a complementary analgesic modality, percutaneous electrical nerve stimulation (PENS), for the treatment of chronic low back pain (CLBP) in community-dwelling older adults. DESIGN: Randomized, controlled clinical trial. SETTING: University of Pittsburgh Pain Evaluation and Treatment Institute. PARTICIPANTS: Thirty-four English speaking, community-dwelling adults aged 65 and older with CLBP of at least moderate intensity experienced every day or almost every day. INTERVENTION: Subjects were randomized to receive twice-weekly PENS and physical therapy (PT) or sham PENS and physical therapy for 6 weeks. MEASUREMENTS: At baseline, immediately after the 6-week intervention period, and 3 months later, the primary outcome measures pain intensity and pain-related disability were assessed. The secondary outcome measures physical performance (timed chair rise, functional reach, gait speed, static and isoinertial lifting), psychosocial factors (mood, sleep, and life control), and cognitive function (measures of attention, concentration, and mental flexibility) were also collected. RESULTS: Subjects randomized to PENS plus PT displayed significant reductions in pain intensity measures from pre- to posttreatment (P <.001), but the sham PENS plus PT group did not (P =.94). These pain reduction effects were maintained at 3-month follow-up. Similarly, significant reductions in pain-related disability were observed at posttreatment (P =.002) for the PENS plus PT group and were maintained at follow-up, but the sham PENS plus PT group did not show reductions in pain-related disability (P =.81). Of the secondary outcome measures, psychosocial function, timed chair rise, and isoinertial lifting endurance also improved significantly at posttreatment for the PENS plus PT group, and their improvement was sustained at 3-month follow-up, but the sham PENS plus PT did not display significant changes on these measures after treatment. CONCLUSION: This preliminary study suggests that PENS may be a promising treatment modality for community-dwelling older adults with CLBP, as demonstrated by reduction in pain intensity and self-reported disability, and improvement in mood, life control, and physical performance. Larger studies with longer duration of follow-up are needed to validate these findings and support the use of PENS in clinical practice.     

Utilization of medical services for the treatment of acute low back pain

Objective:To assess the utilization of diagnostic and therapeutic medical services for the management of acute low back pain in a primary care setting, and to determine whether such utilization conforms to suggested guidelines for the management of this condition. Study design:A retrospective chart audit of consecutive cases of acute low back pain. Specific elements of the diagnostic and therapeutic approach were judged appropriate or inappropriate based on comparison with published recommendations supported by the medical literature. Setting:The primary care adult practice of a university-affiliated health maintenance organization. Patients:One hundred eighty-three patients presenting with acute low back pain of musculoskeletal origin. Measurements and main results:According to suggested guidelines for the care of acute low back pain, 26% of plain lumbar x-rays (10/38), 66% of computed tomography (CT) and magnetic resonance imaging (MRI) scans (12/18), and 82% (23/28) of subspecialty referrals were categorized as inappropriate. Among patients without indications for these services, 12% (10/85) had received lumbar x-rays, 7% (12/168) had received lumbar MRI or CT scans, and 14% (23/168) had received subspecialty referrals. Underutilization of these services had occurred in 71% (70/98) of patients with an indication for plain lumbar radiography, and 47% (7/15) of patients with potential indications for surgical referral or CT/MRI scanning. Neither overutilization nor underutilization had led to adverse outcomes or delays in diagnosis in this small sample. Conclusions:According to guidelines from the medical literature, the primary care physicians in this study both overutilized and underutilized diagnostic and referral services in cases of acute low back pain. It is necessary to determine whether underutilization of plain lumbar radiography adversely affects diagnostic accuracy and whether overutilization of other services improves important clinical outcomes, given the generally benign natural history of this condition.

Epidemiology of low back pain in the United Arab Emirates

Aims: Low back pain (LBP), a common presenting problem in general practice in the United Arab Emirates (UAE), has received increasing attention in recent decades. We seek to investigate the prevalence of LBP and associated risk factors among people living in the typically hot, humid desert environment of the UAE. Methods: A cross‐sectional questionnaire survey was conducted. The setting was the Primary Health Care (PHC) Clinics in Al‐Ain, UAE. The subjects were a multistage stratified sample of 1304 UAE nationals, 15–70 years of age, who attended PHC clinics for any reason. All subjects were invited to participate. The questionnaire used in the survey is a modified version of the Roland‐Morris scale for evaluating low back pain. The questionnaires were administered during face‐to‐face interviews conducted in Arabic by qualified nurses. Results: Of the total 1304 subject, 1103 (84.5%) living in both urban and rural areas agreed to participate and responded to the study; 586 (53.1%) were men and 517 (46.9%) women. The mean ages and SD of the subjects were 34.9 ± 13.4 years for the men and 33.5 ± 11.8 years for the women. The prevalence of LBP in the present study was 64.6% (95% CI = 60.7–68.5). The results revealed that there were statistically significant differences between men and women with respect to LBP and body mass index (BMI) (P < 0.001), marital status (P < 0.001), occupational status (P < 0.001), housing condition (P < 0.001), and smoking habits (P < 0.001). Back pain had a greater influence on the lifestyle habits of the women than men. Stepwise multiple regression analysis showed that only BMI (OR = 2.54, 95% CI = 2.30–281; P < 0.001), prolonged standing (OR = 6.22, 95% CI = 4.01–9.67; P < 0.0001), weakness in leg (OR = 2.11, 95% CI = 1.16–3.85; P = 0.0142), lifting heavy weights (OR = 6.34, 95% CI = 4.09–9.84; P = 0.019) regular exercise (OR = 12.47, 95% CI = 7.50–20.71; P < 0.001) and smoking habits (OR = 1.61, 95% CI = 1.08–2.38; P < 0.05) had a significant effect on the presence of LBP in these patients. Conclusions: The study showed that the prevalence of back‐related disability was higher among women than men in the UAE. Also, low socio‐economic status and adverse lifestyle habits may constitute risk factors and predictors of LBP.     

Disability,depression and somatization in a low back pain population

Objective: The aim of this study was to determine the prevalence of low back pain (LBP) in a primary care setting population and examine its association with the symptoms of depression and somatization. Methods: This is a cross‐sectional study, utilising a survey carried out in primary health care clinics (PHCs) in Al‐Ain, United Arab Emirates (UAE). A multistage stratified sampling design was used and a representative sample of 1304 UAE nationals aged 18–65 years who attended PHC clinics for any reason were included and 1103 (84.5%) subjects agreed to participate and responded to the questionnaire during a period from June 2001 to January 2002. A specially designed questionnaire with three parts was used for the data collection: socio‐demographic information of the studied subjects, modified version of the Roland‐Morris scale for evaluating back‐related functional disability and SCL‐90 R for depression and somatization subscales was used to assess depressive and somatic symptoms. Results: Of the total number of subjects surveyed (1103), 586 (53.1%) were men and 517 (46.9%) women. The mean age was 34.9 ± 13.4 years for men and 33.5 ± 11.8 years for women. The prevalence of LBP in the studied subjects was 64.7% (95% CI, 60.7–68.5] with 46.7% among men and 53.3% among women. There were a significant differences between the subjects with LBP and without LBP with respect to gender (P < 0.001), body mass index (BMI) (P < 0.001), occupational status (P < 0.001) and living environment (P = 0.016). Functional disability was higher in patients with LBP. Young patients in aged 15–34 years, patients with preparatory/secondary educational level and students showed higher depressive symptoms. A similar pattern was found in patients with somatic symptoms. Factor analysis revealed a strong association between depression and somatization in LBP patients. Conclusions: Functional disability was higher in with LBP. Furthermore, symptoms of depression and somatization are prevalent among LBP patients.

Development of a booster intervention for graded sensorimotor retraining (RESOLVE) in people with persistent low back pain: A nested,randomised, feasibility trial

Introduction

Low back pain contributes to an increasing global health burden exacerbated by unsustained improvements from current treatments. There is a need to develop, and test interventions to maintain initial improvements from low back pain treatments. One option is to implement a booster intervention. This study aimed to develop and test the feasibility of implementing a booster intervention delivered remotely to supplement the benefits from a complex intervention for chronic low back pain.

Method

This study was nested in the RESOLVE trial. The booster intervention was developed by an expert group, including a clinical psychologist, exercise physiologist and physiotherapists, and based on a motivational interviewing framework. We developed a conversational flow chart to support the clinician to guide participants towards achieving their pre-specified personal goals and future low back pain self-management. Participants with chronic low back pain who were aged over 18 years and fluent in English were recruited. The booster intervention was delivered in one session, remotely, by telephone. The intervention was considered feasible if: participants were able to be contacted or <3 contacts were necessary to arrange the booster session; there were sufficient willing participants (<15% of sample unwilling to participate); and participants and research clinicians reported a perceived benefit of >7/10.

Results

Fifty participants with chronic non-specific low back pain were recruited to test the feasibility of implementing the booster intervention. Less than three contact attempts were necessary to arrange the booster session, only one participant declined to participate. Participants perceived the session to be beneficial; on a 0 to 10 scale of perceived benefit, the average score recorded was 8.3 (SD 2.0). Clinicians also reported a moderate perceived benefit to the participant; the average score recorded by clinicians was 6.3 (SD 1.6).

Conclusion

We developed a step by step, simple booster intervention that was perceived to be beneficial to participants with chronic low back pain. The booster can feasibly be delivered remotely following a complex intervention.     

Patterns and determinants of multiple provider use in patients with acute low back pain

OBJECTIVE: To describe the patterns of provider use associated with an acute episode of nonspecific low back pain and their impact on cost. METHODS: The analysis is based on a prospective cohort study of patients with acute low back pain followed until they recovered completely or to 6 months. Patients were followed after an initial visit to one of four provider types: private primary care physician, chiropractor, orthopedic surgeon, or HMO primary care physician. Follow-up interviews were conducted at baseline, 2, 4, 8, 12, and 24 weeks; 1,580 (97%) of the participants completed the 6-month follow-up. MAIN RESULTS: Seventy-nine percent of patients saw only the initial provider who began their care for low back pain. Logistic regression revealed that duration of pain prior to initial visit, sciatica, higher Roland disability score, days to functional recovery, interval to complete recovery, referral by initial provider, disk attribution, satisfaction, and the type of index provider were significantly (p<.05) associated with seeking care from multiple provider types. Age, race, gender, and education were not significant. The adjusted proportions of multiple provider type use were 14% (95% confidence interval [CI] 11%, 17%) for the private primary care provider stratum; 19% (95% CI 16%, 23%) for the chiropractic stratum; 30% (95% CI 23%, 37%) for the orthopedic stratum; and 9% (95% CI 5%, 14%) for the HMO primary care physician stratum. Cost of seeing only the index provider was $439 (95% CI $404, $475), and cost of seeing multiple provider types was $1,137 (95% CI $1, 064, $1,211) based on the adjusted model. CONCLUSIONS: Use of multiple provider types, is associated with several factors, one of which is the initial provider type. The cost of such use is significant.

Function and back symptoms in older adults

OBJECTIVES: To determine the relationship between back symptoms and limitations in nine specific functional activities. DESIGN: A cross-sectional study. SETTING: This study was conducted as part of the Framingham Heart Study, a population-based study performed on a representative sample of community-living residents of Framingham, Massachusetts. PARTICIPANTS: Subjects consisted of 1,007 surviving members of the original cohort who participated in the 22nd Biennial Examination in 1992-93. Ages ranged from 70 to 100. MEASUREMENTS: Subjects were asked whether they experienced pain, aching, or stiffness in their back on most days and whether they had difficulty performing nine specific functional skills. Odds ratios (ORs) and confidence intervals are reported for the entire sample and within categories of sex. The proportion of functional limitations attributable to back symptoms and the proportion of limitations ascribed by subjects to back symptoms among subjects with these limitations are also reported. RESULTS: The results provide evidence of a relationship between back symptoms and functional limitations. ORs were highest for difficulty standing in one place for about 15 minutes, pushing or pulling a large object, and walking half a mile. Of those with back symptoms, 43% to 63% of limitations in activities were due to back symptoms. Among all subjects, back symptoms were so prevalent that 18% to 34% of all functional limitations were attributable to back symptoms. The association between back symptoms and functional limitations was especially strong in women. CONCLUSION: Back symptoms account for a large percentage of functional limitations in older adults, especially in women.     

Clin-STAR corner: 2021 update in musculoskeletal pain in older adults with a focus on osteoarthritis-related pain

Chronic musculoskeletal (MSK) pain remains a leading cause of disability and functional impairment among older adults and is associated with substantial societal and personal costs. Chronic pain is particularly challenging to manage in older adults because of multimorbidity, concerns about treatment-related harm, as well as older adults' beliefs about pain and its management. This narrative review presents data on nine high-quality, peer-reviewed clinical trials published primarily over the past two years that focus on MSK pain management in older adults, of which four were comprehensively reviewed. These studies address contributors to knee osteoarthritis (OA) pain (insomnia), provide evidence for digital delivery or artificial intelligence driven behavioral interventions and potentially more efficient/equally effective modes of delivering glucocorticoids for OA; each of the selected studies have potential for scalability and meaningful impact in the care of older adults.
