Incorporating Persistent Pain in Phenotypic Frailty Measurement and Prediction of Adverse Health Outcomes

Temporal association between chronic pain and frailty occurrence, and the modifiable role of a healthy lifestyle in Chinese middle-aged and older population: a community based, prospective cohort study

BACKGROUND

While western studies suggest a temporal association between chronic pain and frailty, as well as the impacts of healthy lifestyle interventions, these relationships remain underexplored in the Chinese population.

METHODS

We conducted a longitudinal study with 13,601 participants from the China Health and Retirement Longitudinal Study, covering 2011-2018. Pain was assessed via self-report, and frailty was evaluated using a 29-item deficit-accumulation frailty index. Five lifestyle factors, such as physical activity, alcohol consumption, smoking, body mass index, and sleep duration, were assessed, and the participants were categorized into favorable, intermediate, and unfavorable lifestyle groups.

RESULTS

During the 7-year follow-up, 3,356 cases of frailty were discerned. Participants who reported pain at baseline assessment had a higher risk of developing frailty compared to those without pain (hazard ratio [HR] = 1.10; 95%confidence interval [CI], 1.03-1.19). This association was particularly evident in middle-aged individuals (HR = 1.13; 95% CI, 1.01-1.26). Participants with severe pain at baseline assessment had a 1.16-fold higher risk of frailty (95%CI, 1.05-1.28, Ptrend= 0.0067). Among the participants with mild or moderate pain at baseline assessment, the risk of developing frailty was significantly reduced by a favorable lifestyle (HR = 0.62; 95% CI, 0.51-0.76) or intermediate lifestyle (HR = 0.83; 95% CI, 0.70-0.98). Additionally, a favorable lifestyle was significantly associated with a decreased risk of developing frailty in the participants with severe pain at baseline assessment (HR = 0.75; 95%CI, 0.59-0.96). Mediation analysis indicated that a healthy lifestyle could mitigate 2.97% of frailty risk associated with chronic pain.

CONCLUSIONS

Chronic pain is strongly associated with an increased risk of developing frailty in Chinese older population, but the implementation of healthy lifestyles can significantly reduce this risk.

Association of chronic pain with frailty and pre-frailty in older adults: A systematic review and meta-analysis

PURPOSE

Frailty has been demonstrated to correlate with chronic pain (CP). This study aimed to estimate the risk of frailty/pre-frailty and evaluate the potential bidirectional relationship between frailty/pre-frailty and CP.

METHODS

A systematic search was conducted across ten databases, covering literature from their inception through November 23, 2024. Two independent reviewers screened relevant studies, assessed study quality, and extracted data. All analyses were performed using R software, version 4.3.1.

RESULTS

A total of 25,904 participants aged ≥ 60 years were included in 33 studies. CP significantly increased the risk of frailty (OR = 1.91, 95 % CI: 1.47-2.47; I2 = 82 %, p < 0.01), whereas no significant association was found between frailty/pre-frailty and CP risk (OR = 1.52, 95 % CI: 0.66-3.50; I2 = 98 %, p < 0.01). Eleven studies were classified as high quality, and the remainder as moderate quality.

CONCLUSIONS

No evidence supports a bidirectional relationship between frailty/pre-frailty and CP. Nonetheless, addressing and managing CP in older adults may mitigate the risk of frailty and promote healthy aging.

Risk factors for falls in older people with pre-frailty: A systematic review and meta-analysis

BACKGROUND

Frailty is considered highly prevalent among the elderly, and falls are a severe adverse event that occurs at a significantly higher rate in frail elderly patients, leading to serious consequences. The pre-frailty stage represents a reversible transitional state between health and frailty, and targeted interventions for pre-frail older adults can effectively reduce the incidence of falls in this population. Existing studies have not definitely identified the risk factors for falls in pre-frail older adults. This paper explores the relevant risk factors for falls in pre-frail older adults.

METHODS

PubMed, Embase, Web of Science, Cochrane Library, CBM, CNKI, Wan fang, and VIP databases were searched for studies published from inception to 2023, without language restrictions. Observational studies were included in this systematic review that analyzed risk factors for accidental falls in pre-frail older adults. The NOS scale was used to evaluate the quality of cohort studies and case-control studies, while the AHRQ scale was used to evaluate the quality of the cross-sectional study. We utilized odds ratios (OR) and their corresponding 95 % confidence intervals (CI) to describe the statistical indicators. OR and 95 % CI values were directly extracted and organized in Excel. In cases where OR and CI values were not directly available, we extracted β and p values, calculated Exp using functions, and subsequently derived OR and 95 % CI using formulas. Finally, data pertaining to each risk factor were incorporated into RevMan 5.4 software for statistical analysis and effect size synthesis. We performed tests for heterogeneity and evaluated publication bias.

RESULTS

A total of 14,370 studies were initially identified, and 26 studies were included in the systematic review. Among these studies, 14 were of high quality, while the remaining 12 were of moderate quality. A total of 16 risk factors were identified as potential risk factors for falls in pre-frail older adults. Significant risk factors were peripheral neuropathy(OR = 3.18, 95 %CI:3.02-3.35), decreased gait speed(OR = 1.90, 95 %CI:1.60-2.27), decreased ability to perform activities of daily living(OR = 1.57, 95 % CI:1.42-1.75), grip strength decreases(OR = 1.53, 95 % CI:1.17-2.00), gender (female)(OR = 1.51, 95 % CI:1.39-1.64), pain(OR = 1.47, 95 %CI:1.41-1.54), history of falls(OR = 1.20, 95 %CI:1.13-1.28) and age(OR = 1.10, 95 %CI:1.07-1.14).

CONCLUSIONS

The occurrence of falls in pre-frail older adults is associated with multiple risk factors. These risk factors can provide clinical nursing staff with specific focal points for monitoring this population and devising targeted fall prevention measures, with the aim of reducing the incidence of falls in pre-frail older adults.

REGISTRATION

The systematic review was registered on the International Prospective Register of Systematic Review (CRD42023450670).

The vicious cycle of frailty and pain: a two-sided causal relationship revealed

Background

The decline in physiological functions in the older people is frequently accompanied with pain and frailty, yet the causal connection between frailty and pain remains uncertain. In this study, we utilized a two-sample Mendelian randomization (MR) approach to investigate the potential causal association between frailty and pain.

Methods

Two-sample bidirectional MR was conducted using summary data from genome-wide association studies to examine the potential causal relationship between frailty (defined by the frailty index and frailty phenotype) and pain. Summary genome wide association statistics were extracted from populations of European ancestry. We also investigated the causal relationship between frailty and site-specific pain, including joint pain, limb pain, thoracic spine pain and low back pain. Causal effects were estimated using the inverse variance weighting method. Sensitivity analyses were performed to validate the robustness of the results.

Results

Genetic predisposition to frailty was associated with an increased risk of pain (frailty phenotype odds ratio [OR]: 1.73; P = 3.54 × 10-6, frailty index OR: 1.36; P = 2.43 × 10-4). Meanwhile, individuals with a genetic inclination toward pain had a higher risk of developing frailty. Regarding site-specific pain, genetic prediction of the frailty phenotype increased the occurrence risk of joint pain, limb pain and low back pain. Reverse MR analysis further showed that limb pain and low back pain were associated with an increased risk of frailty occurrence.

Conclusion

This study presented evidence supporting a bidirectional causal relationship between frailty and pain. We highlighted the significance of addressing pain to prevent frailty and recommend the inclusion of pain assessment in the evaluation system for frailty.

Association between persistent musculoskeletal pain and incident sarcopenia in China: the mediating effect of depressive symptoms

Objective

To evaluate the association between musculoskeletal pain and incident sarcopenia and further explore the mediating effect of depressive symptoms among middle-aged and older Chinese adults.

Methods

Using the data from the China Health and Retirement Longitudinal Study 2011 and 2015, we included 12,788 participants in the cross-sectional analysis and 8,322 for the longitudinal analysis. Musculoskeletal pains located in the neck, back, waist, shoulder, arm, wrist, leg, knee, and ankle were self-reported at baseline and follow-up. The diagnosis criteria of sarcopenia was based on the Asian Working Group for Sarcopenia 2019. Multivariable logistic regression models were used to evaluate the association between musculoskeletal pain, and the Karlson-Holm-Breen (KHB) method was used to explore the mediating effect of depressive symptoms.

Results

Over the 4-year follow-up, 445 participants were identified with incident sarcopenia. In the longitudinal analysis, participants with baseline musculoskeletal pain (adjusted odds ratio (OR): 1.37, 95% confidence interval (CI): 1.07-1.76), persistent musculoskeletal pain (OR:1.68, 95%CI: 1.28-2.24), and persistent waist pain (OR:1.46, 95%CI: 1.04-2.03) were significantly associated with increased the risk of incident sarcopenia. Furthermore, depressive symptoms were found to partially mediate the association between musculoskeletal pain and incident sarcopenia.

Conclusion

Persistent musculoskeletal pain, especially in waist area, was positively associated with a higher risk of sarcopenia among the middle-aged and older Chinese. Depressive symptoms played a partial mediating role in this association.

Patients' strategies for numeric pain assessment: a qualitative interview study of individuals with hypermobile Ehlers-Danlos Syndrome

PURPOSE

Chronic pain is a common feature of hypermobile Ehlers-Danlos Syndrome (hEDS), yet how patients assess and communicate their pain remains poorly understood. The objective of the present study was to explore the use of numeric pain assessment in individuals with hEDS, from a patient-centered perspective.

MATERIALS AND METHODS

Our analysis is based on in-depth qualitative interviews. The interviews were conducted over the phone. Our participants were patients living with hEDS (N = 35). Interviews were recorded, transcribed, and analyzed to identify factors related to their use of these pain assessment instruments.

RESULTS

Three primary themes emerged from these data, namely, (1) confusion around the quantification of multidimensional pain, (2) the subjectivity of pain experience, and (3) a strategic use of assessments for practical purposes beyond the accurate representation of pain.

These results demonstrate the need for caution in relying exclusively on numeric pain assessment instruments. We conclude with a brief proposal for a clinical communication strategy that may help to address the limitations of numeric pain assessment that were identified in our interviews.

Assessment of relationships between frailty and chronic pain: a bidirectional two-sample Mendelian randomisation study

BACKGROUND

Previous observational studies have indicated a complex association between chronic pain and frailty. This study aimed to examine the bidirectional causal relationship between frailty and chronic pain and to quantify mediating effects of known modifiable risk factors.

METHODS

A bidirectional two-sample Mendelian randomisation (MR) analysis was applied in this study. Summary genome-wide association statistics for frailty, as defined by both frailty index (FI) and Fried Frailty Score (FFS), pain at seven site-specific chronic pain (SSCP) (headache, facial, neck/shoulder, stomach/abdominal, back, hip and knee) and multisite chronic pain (MCP) were extracted from populations of European ancestry. Genetic instrumental variables strongly correlated with each exposure were selected. The inverse-variance-weighted method was the primary method used in the MR, supplemented by a range of sensitivity and validation analyses. Two-step MR analysis was undertaken to evaluate the mediating effects of several proposed confounders.

RESULTS

Genetically predicted higher FI and FFS were associated with an increased risk of MCP and specific types of SSCP, including neck/shoulder pain, stomach/abdominal pain, back pain, hip pain and knee pain. In the reverse direction analysis, genetic liability to MCP was found to be associated with increased FI and FFS. These results remained consistent across sensitivity and validation assessments. Two-step MR suggested a mediating role for body mass index, smoking initiation, physical inactivity, educational attainment and depression.

CONCLUSIONS

Our research provided genetic evidence that the association between frailty and chronic pain was bidirectional where the coexistence of both conditions will exacerbate each other.

Relationship between chronic pain, depressive symptoms, and functional disability in community-dwelling older adults: mediating role of frailty

BACKGROUND

Borim et al. showed that older adults with chronic pain exhibited more depressive symptoms and frailty components. Depressive symptoms were associated with more frailty components, and those with more depressive symptoms and frailty faced greater limitations in IADL performance. Frailty appears to mediate the pathway from chronic pain to functional impairment Chronic pain is directly associated with depressive symptoms and frailty. Chronic pain is not directly associated with functional disability. Depression and frailty are both directly associated with functional disabilities. Frailty mediates the association between chronic pain and functional disability. Depression; Disability evaluation; Frailty; Frail elderly.

OBJECTIVE

To evaluate the direct and indirect effects of chronic pain, depressive symptoms, frailty components, and functional disability through a pathway analysis approach in a sample of community-dwelling older adults.

METHODS

Data of 419 participants were cross-sectionally evaluated for the presence of depressive symptoms (Geriatric Depression Scale [15 items]), physical frailty components (phenotype criteria), chronic pain, and limitations in performing instrumental activities of daily living (functional disability scale by Lawton and Brody). Structural equation modeling via path analysis was used to explore the direct and indirect effects among these four variables. Statistical significance was set at p<0.05.

RESULTS

Of the total participants, 69.8% were women and 59.3% had low education (1-4 years); the mean age was 80.3±4.6 years. Chronic pain and depressive symptoms were directly related and were associated to frailty. The number of frailty components and depressive symptoms were directly associated with functional disability. Frailty had an indirect effect on the association between chronic pain, depressive symptoms, and functional disabilities.

CONCLUSION

The pathway from chronic pain and depressive symptoms to functional disability is potentially mediated by the number of frailty components.

Managing Musculoskeletal Pain in Older Adults Through a Digital Care Solution: Secondary Analysis of a Prospective Clinical Study

BACKGROUND

Aging is closely associated with an increased prevalence of musculoskeletal conditions. Digital musculoskeletal care interventions emerged to deliver timely and proper rehabilitation; however, older adults frequently face specific barriers and concerns with digital care programs (DCPs).

OBJECTIVE

This study aims to investigate whether known barriers and concerns of older adults impacted their participation in or engagement with a DCP or the observed clinical outcomes in comparison with younger individuals.

METHODS

We conducted a secondary analysis of a single-arm investigation assessing the recovery of patients with musculoskeletal conditions following a DCP for up to 12 weeks. Patients were categorized according to age: ≤44 years old (young adults), 45-64 years old (middle-aged adults), and ≥65 years old (older adults). DCP access and engagement were evaluated by assessing starting proportions, completion rates, ability to perform exercises autonomously, assistance requests, communication with their physical therapist, and program satisfaction. Clinical outcomes included change between baseline and program end for pain (including response rate to a minimal clinically important difference of 30%), analgesic usage, mental health, work productivity, and non-work-related activity impairment.

RESULTS

Of 16,229 patients, 12,082 started the program: 38.3% (n=4629) were young adults, 55.7% (n=6726) were middle-aged adults, and 6% (n=727) were older adults. Older patients were more likely to start the intervention and to complete the program compared to young adults (odds ratio [OR] 1.72, 95% CI 1.45-2.06; P<.001 and OR 2.40, 95% CI 1.97-2.92; P<.001, respectively) and middle-aged adults (OR 1.22, 95% CI 1.03-1.45; P=.03 and OR 1.38, 95% CI 1.14-1.68; P=.001, respectively). Whereas older patients requested more technical assistance and exhibited a slower learning curve in exercise performance, their engagement was higher, as reflected by higher adherence to both exercise and education pieces. Older patients interacted more with the physical therapist (mean 12.6, SD 18.4 vs mean 10.7, SD 14.7 of young adults) and showed higher satisfaction scores (mean 8.7, SD 1.9). Significant improvements were observed in all clinical outcomes and were similar between groups, including pain response rates (young adults: 949/1516, 62.6%; middle-aged adults: 1848/2834, 65.2%; and older adults: 241/387, 62.3%; P=.17).

CONCLUSIONS

Older adults showed high adherence, engagement, and satisfaction with the DCP, which were greater than in their younger counterparts, together with significant clinical improvements in all studied outcomes. This suggests DCPs can successfully address and overcome some of the barriers surrounding the participation and adequacy of digital models in the older adult population.

The bidirectional relationship between chronic joint pain and frailty: data from the Investigating Musculoskeletal Health and Wellbeing cohort

BACKGROUND

Pain and frailty are associated, but this relationship is insufficiently understood. We aimed to test whether there is a unidirectional or bidirectional relationship between joint pain and frailty.

METHODS

Data were from Investigating Musculoskeletal Health and Wellbeing, a UK-based cohort. Average joint pain severity over the previous month was assessed using an 11-point numerical rating scale (NRS). Frailty was classified as present/absent using the FRAIL questionnaire. Multivariable regression assessed the association between joint pain and frailty, adjusted for age, sex, and BMI class. Two-wave cross-lagged path modelling permitted simultaneous exploration of plausible causal pathways between pain intensity and frailty at baseline and 1-year. Transitions were assessed using t-tests.

RESULTS

One thousand one hundred seventy-nine participants were studied, 53% female, with a median age of 73 (range 60 to 95) years. FRAIL classified 176 (15%) participants as frail at baseline. Mean (SD) baseline pain score was 5.2 (2.5). Pain NRS ≥ 4 was observed in 172 (99%) of frail participants. Pain severity was associated with frailty at baseline (aOR 1.72 (95%CI 1.56 to 1.92)). In cross-lagged path analysis, higher baseline pain predicted 1-year frailty [β = 0.25, (95%CI 0.14 to 0.36), p < 0.001] and baseline frailty predicted higher 1-year pain [β = 0.06, (95%CI 0.003 to 0.11), p = 0.040]. Participants transitioning to frailty over one year had higher mean pain scores (6.4 (95%CI 5.8 to 7.1)) at baseline than those who remained non-frail (4.7 (95%CI 4.5 to 4.8)), p < 0.001.

CONCLUSIONS

The bidirectional relationship between pain and frailty could lead to a vicious cycle in which each accelerates the other's progression. This justifies attempts to prevent frailty by addressing pain and to include pain measures as an outcome in frailty studies.

Does depression mediate the pain-frailty relationship? Latent variables approach

Frailty is highly prevalent among older adults. This study aims to add evidence to the mediational role of depression in the pain-frailty relationship. Data came from a sample of 2578 Spanish older adults recruited from the Survey of Health, Aging, and Retirement in Europe (SHARE). A set of competing structural equation models were performed: (a) independent prediction, (b) full mediation, and (c) partial mediation. Results showed a better fit for the partial mediation model. This model was extended including covariates. The effects of pain and depression remained relevant in the final model, which explained 91% of the frailty variance. These findings support the relevance of the pain-depression dyad in frailty development. Although the pain shows a direct impact on frailty, this association is partially mediated by depression. The interplay of these conditions could be crucial for treatment effectiveness.

The role of frailty in the association between depression and fall risk among older adults

OBJECTIVES

Although there is a recognized association between depression and greater fall risk among older adults, the mechanisms explaining this association are unclear. This study evaluated the role of frailty, a common geriatric syndrome, in determining greater risk of falls among older adults with depression.

METHOD

We used longitudinal data from three biennial waves of the Health and Retirement Study (HRS; 2010-2014). The sample included community-dwelling survey respondents age ≥ 65 who participated in objective physiological measures. Major Depression (MD) was measured using Composite International Diagnostic Interview for depression short form. Frailty was measured using criteria outlined in the frailty phenotype model. Causal mediation analysis was used to differentiate the direct effect of depression and indirect effect mediated by frailty on falls, fall injuries, and multiple falls.

RESULTS

Major depression was associated with significantly greater odds of experiencing a fall (OR: 1.91; 95% CI: 1.31, 2.77), fall injury (OR: 1.86; 95% CI: 1.17, 2.95), and multiple falls (OR: 2.26; 95% CI: 1.52, 3.37) over a two-year period. Frailty was a significant mediator of the effects of depression on falls and multiple falls, accounting for approximately 18.9% and 21.3% of the total effects, respectively. We found no evidence of depression-frailty interaction. Sensitivity analyses showed that results were robust to unmeasured confounding and alternative operationalizations of depression.

CONCLUSION

Frailty explains a significant proportion of increased likelihood of falls among older adults with depression. Treatment and management of frailty symptoms may be an important components of fall prevention among older adults with depression.

Pain and the Alzheimer's Disease and Related Dementia Spectrum in Community-Dwelling Older Americans: A Nationally Representative Study

CONTEXT

Pain is a significant concern among older adults with Alzheimer's disease and related dementias (ADRD).

OBJECTIVES

Examine the association between cognitive impairment across the ADRD spectrum and pain assessment and treatment in community-dwelling older Americans.

METHODS

This cross-sectional, population-based study included 16,836 community-dwelling participants ≥ 50 years in the 2018 Health and Retirement Study. ADRD, assessed by validated cognitive measures, was categorized into "dementia," "cognitive impairment, no dementia (CIND)" and "intact cognition." Pain assessment included pain presence (often being troubled with pain), pain severity (degree of pain most of the time [mild/moderate/severe]), and pain interference (pain making it difficult to do usual activities). Pain treatment included recent use of over-the-counter pain medications and opioids (past 3 months), and regular intake of prescriptions for pain.

RESULTS

Dementia were associated with lower likelihood of reporting pain presence (Odds Ratio [OR]= 0.61, P = 0.01), pain interference (OR = 0.46, P < 0.001), reporting lower pain severity (e.g., moderate vs. no: Relative Risk Ratio = 0.38, P < 0.001), and lower likelihood of receiving pain treatment, that is, recent use of over-the-counter pain medications (OR = 0.60, P = 0.02) and opioids (OR = 0.33, P < 0.001), and regular intake of prescriptions for pain (OR = 0.461, P = 0.002). CIND was associated with reporting lower pain severity (e.g., moderate vs. no: Relative Risk Ratio = 0.75, P = 0.021), lower likelihood of reporting pain interference (OR = 0.79, P = 0.045) and recent over-the-counter pain medication use (OR = 0.74, P = 0.026).

CONCLUSION

CIND and dementia increased the risk of under-report and under-treatment of pain. Systematic efforts are needed to improve pain recognition and treatment among older adults with cognitive impairment, regardless of dementia diagnosis.

Frailty Risks of Prescription Analgesics and Sedatives across Frailty Models: the Health and Retirement Study

INTRODUCTION

Limited evidence for incident frailty risks associated with prescription analgesics and sedatives in older (≥ 65 years) community-living adults prompted a more comprehensive investigation.

METHODS

We used data from older Health and Retirement Study respondents and three frailty models (frailty index, functional domain, frailty phenotype with 8803, 10,470, and 6850 non-frail individuals, respectively) and estimated sub-hazard ratios of regular prescription drug use (co-use, analgesic use, and sedative use), by frailty model. We addressed confounding with covariate adjustment and propensity score matching approaches.

RESULTS

The baseline prevalence of analgesic and sedative co-use, analgesic use, and sedative use among non-frail respondents was 1.8%, 12.8%, and 4.7% for the frailty index model, 4.2%, 16.2%, and 5.3% for the functional domain model, and 4.3%, 15.4%, and 6.1% for the frailty phenotype model, respectively. Cumulative frailty incidence over 10 years was 39.3%, 36.1%, and 14.2% for frailty index, functional domain, and frailty phenotype models, respectively; covariate-adjusted sub-hazard ratio estimates were 2.00 (1.63-2.45), 1.83 (1.57-2.13), and 1.68 (1.21-2.33) for co-use; 1.72 (1.56-1.89), 1.38 (1.27-1.51), and 1.51 (1.27-1.79) for analgesic use; and 1.46 (1.24-1.72), 1.25 (1.07-1.46), and 1.31 (0.97-1.76) for sedative use. Frailty risk ranking (co-use > analgesic use > sedative use) persisted across all model sensitivity analyses.

DISCUSSION

Consistently significant frailty risk estimates of regular prescription analgesic and sedative co-use and of prescription analgesic use support existing clinical, public health, and regulatory guidance on opioid and benzodiazepine co-prescription, on opioid prescription, and on NSAID prescription. Frailty phenotype measurement administration limited power to detect significant frailty risks. Research into specific pharmaceutical exposures and comparison of results across cohorts will be required to contribute to the deprescribing evidence base.

Chronic Conditions, Persistent Pain, and Psychological Distress Among the Rural Older Adults: A Path Analysis in Shandong, China

Psychological distress were found to be associated with chronic conditions and persistent pain. However, few studies explored the underlying pathways between them. This study aimed to analyze the path of chronic conditions and persistent pain on psychological distress through sleep quality and self-rated health. A total of 2,748 rural older people in Shandong, China were included in this study. Path analysis was performed by using Mplus 8.3 to examine the associations between chronic conditions, persistent pain, sleep quality, self-rated health, and psychological distress after adjusting for age, gender, education, and household income. The prevalence of psychological distress among the older adults in this study was 47.49%. Chronic conditions and persistent pain were indirectly associated with psychological distress through six mediating pathways: (1) the path from chronic conditions to psychological distress through sleep quality (β = 0.041, 95%CI: 0.015-0.067) and self-rated health (β = 0.064, 95%CI: 0.038-0.091), respectively, and a chain mediation existed (β = 0.007, 95% CI: 0.000-0.014); (2) the path of persistent pain and psychological distress through sleep quality (β = 0.058, 95% CI: 0.014-0.102) and self-rated health (β = 0.048, 95% CI: 0.000-0.096), respectively, also the chain mediation found (β = 0.009, 95% CI: 0.005-0.014). Psychological distress was associated with chronic conditions and persistent pain through decreased sleep quality and self-rated health among Chinese rural older people. Multi-pronged targeted intervention should be taken for older adults with chronic conditions and persistent pain.

Barriers and facilitators to older adults' use of nonpharmacologic approaches for chronic pain: a person-focused model

ABSTRACT

In the context of the opioid epidemic and the growing population of older adults living with chronic pain, clinicians are increasingly recommending nonpharmacologic approaches to patients as complements to or substitutes for pharmacologic treatments for pain. Currently, little is known about the factors that influence older adults' use of these approaches. We aimed to characterize the factors that hinder or support the use of nonpharmacologic approaches for pain management among older adults with multiple morbidities. We collected semistructured qualitative interview data from 25 older adults with multiple morbidities living with chronic pain for 6 months or more. Transcripts were coded to identify factors that hindered or supported participants' use of various nonpharmacologic approaches. We used the constant comparative method to develop a person-focused model of barriers and facilitators to participants' use of these approaches for chronic pain management. Participants described a wide range of factors that influenced their use of nonpharmacologic approaches. We grouped these factors into 3 person-focused domains: awareness of the nonpharmacologic approach as relevant to their chronic pain, appeal of the approach, and access to the approach. We propose and illustrate a conceptual model of barriers and facilitators to guide research and clinical care. This study identifies numerous factors that influence patients' use of nonpharmacologic approaches, some of which are not captured in existing research or routinely addressed in clinical practice. The person-centered model proposed may help to structure and support patient-clinician communication about nonpharmacologic approaches to chronic pain management.

Development and Psychometric Validation of a New Scale for Assessment and Screening of Frailty Among Older Indians

Background

Frailty is a major challenge for healthcare systems in ageing societies. This dynamic state of health is a reflection of reduced reserve in various organ systems and enhanced vulnerability to stressors. Research in this area of geriatrics and gerontology is limited in low- and middle-income countries (LMICs) like India. This study is directed at development of a culturally appropriate and validated assessment scale for frailty among older Indians.

Methods

After extensive review of the literature on existing scales, a preliminary draft scale was formed. This draft was pre- and pilot-tested to check feasibility and modified accordingly. The final scale was validated on 107 older adults by confirmatory factor analysis and was named the Frailty Assessment and Screening Tool (FAST). The Fried’s frailty phenotype was also administered on the same 107 older adults and scores of both were co-related. Suitable cut-off scores were found for frail and pre-frail older adults.

Results

The final version of the FAST consisted of 14 questions pertaining to 10 domains. It has good reliability. Cronbach’s alpha co-efficient was 0.99; test–retest reliability was 0.97 and validity by confirmatory factor analysis was adequate. The Kaiser–CMeyer–Olkin (KMO) of sampling adequacy was 0.699, and Bartlett’s test of sphericity was significant (χ² = 353.471, p < 0.001). FAST scores had a cut-off of ≥ 7/14 for frail and ≥ 5/14 for pre-frail elderly.

Conclusion

The FAST is a validated tool with good psychometric properties. It is expected that it will be helpful in screening pre-frail and frail older adults in India and other LMICs and guide in clinical decision making for intervention.

Prevalence of frailty and pain in hospitalised adult patients in an acute hospital: a protocol for a point prevalence observational study

INTRODUCTION

Frailty and pain are associated with adverse patient clinical outcomes and healthcare system costs. Frailty and pain can interact, such that symptoms of frailty can make pain assessment difficult and pain can exacerbate the progression of frailty. The prevalence of frailty and pain and their concurrence in hospital settings are not well understood, and patients with cognitive impairment are often excluded from pain prevalence studies due to difficulties assessing their pain. The aim of this study is to determine the prevalence of frailty and pain in adult inpatients, including those with cognitive impairment, in an acute care private metropolitan hospital in Western Australia.

METHODS AND ANALYSIS

A prospective, observational, single-day point prevalence, cross-sectional study of frailty and pain intensity of all inpatients (excluding day surgery and critical care units) will be undertaken. Frailty will be assessed using the modified Reported Edmonton Frail Scale. Current pain intensity will be assessed using the PainChek smart-device application enabling pain assessment in people unable to report pain due to cognitive impairment. Participants will also provide a numerical rating of the intensity of current pain and the worst pain experienced in the previous 24 hours. Demographic and clinical information will be collected from patient files. The overall response rate of the survey will be reported, as well as the percentage prevalence of frailty and of pain in the sample (separately for PainChek scores and numerical ratings). Additional statistical modelling will be conducted comparing frailty scores with pain scores, adjusting for covariates including age, gender, ward type and reason for admission.

Suffering in silence: a qualitative study of older adults' experiences of living with long-term musculoskeletal pain at home

Long-term musculoskeletal pain is a major, disabling, and often undertreated health problem among the increasing number of older adults worldwide. However, there is limited knowledge of community-dwelling older adults' experiences of living with this type of pain. The aim of the study was to deepen the understanding of the phenomenon: how older adults experience living with long-term musculoskeletal pain at home. The study design was an inductive qualitative Reflective Lifeworld Research approach grounded in phenomenological epistemology. Data were obtained from 20 community-dwelling older adults, aged 72-97 years. Data were collected through open-ended interviews and analyzed to understand the meanings of the phenomenon. The essence of the phenomenon entailed suffering in silence and encompassed the following constituents: loneliness and restrictions in daily living; ways to endure and distract from pain; not being taken seriously; fear of the future; and valuing joy and meaning in life. Living with long-term musculoskeletal pain restricts access to the world and leads to a suffering in silence. Finding ways to endure and distract from pain and to focus on issues that give joy and meaning in life is predominant in efforts to balance restraints from pain in life. Suffering is reinforced by loneliness, a sense of not being taken seriously by health care providers and fear of an uncertain future. It is necessary to foster increased attentiveness and sensitivity in meeting the needs of each older adult and provide a care that alleviates suffering and preserves and promotes health and well-being.

Frailty Phenotype and Cause-Specific Mortality in the United States

BACKGROUND

Frailty is a common condition among older adults increasing risk of adverse outcomes including mortality; however, little is known about the incidence or risk of specific causes of death among frail individuals.

METHODS

Data came from the Health and Retirement Study (HRS; 2004-2012), linked to underlying cause-of-death information from the National Death Index (NDI). Community-dwelling HRS participants aged 65 and older who completed a general health interview and physical measurements (n = 10,490) were included in analysis. Frailty was measured using phenotypic model criteria-exhaustion, low weight, low energy expenditure, slow gait, and weakness. Underlying causes of death were determined using International Classification of Diseases, Version 10 codes. We used Cox proportional hazards and competing risks regression models to calculate and compare incidence of cause-specific mortality by frailty status.

RESULTS

During follow-up, prefrail and frail older adults had significantly greater hazard of all-cause mortality compared to individuals without symptoms (adjusted hazard ratio [HR] prefrail: 1.85, 95% CI: 1.51, 2.25; HR frail: 2.75, 95% CI: 2.14, 3.53). Frailty was associated with 2.96 (95% CI: 2.17, 4.03), 2.82 (95% CI: 2.02, 3.94), 3.48 (95% CI: 2.17, 5.59), and 2.87 (95% CI: 1.47, 5.59) times greater hazard of death from heart disease, cancer, respiratory illness, and dementia, respectively.

CONCLUSIONS

Significantly greater risk of mortality from several different causes should be considered alongside the potential costs of screening and intervention for frailty in subspecialty and general geriatric clinical practice. Findings may help investigators estimate the potential impact of frailty reduction approaches on mortality.

Chronic Post-Surgical Pain in the Frail Older Adult

Older adults are the fastest growing segment of the population and surgical procedures in this group increase each year. Chronic post-surgical pain is an important consideration in the older adult as it affects recovery, physical functioning, and overall quality of life. It is increasingly recognized as a public health issue but there is a need to improve our understanding of the disease process as well as the appropriate treatment and prevention. Frailty, delirium, and cognition influence post-operative outcomes in older adults and have been implicated in the development of chronic post-surgical pain. Further research must be conducted to fully understand the role they play in the occurrence of chronic post-surgical pain in the older adult. Additionally, careful attention must be given to the physiologic, cognitive, and comorbidity differences between the older adult and the general population. This is critical for elucidating the proper chronic post-surgical pain treatment and prevention strategies to ensure that the older adult undergoing surgical intervention will have an appropriate and desirable post-operative outcome.

Revisiting the hypothesis of syndromic frailty: a cross-sectional study of the structural validity of the frailty phenotype

BACKGROUND

Fried's Phenotype Model of Frailty (PMF) postulates that frailty is a syndrome. Features of a syndrome are a heterogeneous population that can be split into at least two classes, those presenting and those not presenting the syndrome. Syndromes are characterized by a specific mixture of signs and symptoms which increase in prevalence, from less to more severe classes. So far, the null hypothesis of homogeneity - signs and symptoms of frailty cannot identify at least two classes - has been tested using Latent Class Analysis (LCA) on the five dichotomized components of PMF (unintentional weight loss, exhaustion, weakness, slowness, and low physical activity). The aim of this study is to investigate further the construct validity of frailty as a syndrome using the extension offered by Factor Mixture Models (FMM).

METHODS

LCA on dichotomized scores and FMM on continuous scores were conducted to test homogeneity on the five PMF components in a sample of 1643 community-dwelling older adults living in Québec, Canada (FRéLE).

RESULTS

With dichotomized LCA, three frailty classes were found: robust, prefrail and frail, and the hypothesis of homogeneity was rejected. However, in FMM, frailty was better represented as a continuous variable than as latent heterogeneous classes. Thus, the PMF measurement model of frailty did not meet the features of a syndrome in this study.

CONCLUSION

Using the FRéLE cohort, the PMF measurement model validity is questioned. Valid measurement of a syndrome depends on an understanding of its etiological factors and pathophysiological processes, and on a modelling of how the measured components are linked to these processes. Without these features, assessing frailty in a clinical setting may not improve patient health. Research on frailty should address these issues before promoting its use in clinical settings.

Test-Retest Reliability of Pain Measures in Institutionalized Older Adults: Number of Painful Body Sites, Pain Intensity, and Pain Extent

OBJECTIVE

The reliability of pain assessment in frail and older adults has seldom been assessed. This study aims to assess the test-retest reliability of (1) the number of painful body sites, (2) pain intensity, and (3) pain extent in institutionalized older adults.

METHODS

Seventy-four older adults who were institutionalized were assessed in 2 separate sessions, 2 days to 1 week apart, for pain intensity, number of painful body sites, and pain extent (in pixels) using a vertical pain numeric scale (0 to 10), a body chart divided into 50 body regions, and ImageJ, respectively. Intraclass correlation coefficients (ICCs), standard error of measurement (SEM), and minimal detectable differences (MDDs) were calculated.

RESULTS

In session 1, the mean values (± standard deviation) were 5.54 ± 2.12 points for pain intensity, 4.47 ± 3.27 for number of painful body sites, and 2,726.00 ± 2,322.09 for pain extent. ICCs were 0.82 (95% confidence interval [CI] = 0.72 to 0.89) for pain intensity, 0.89 (95% CI = 0.83 to 0.93) for number of painful body sites, and 0.74 (95% CI = -0.07 to 0.91) for pain area. The MDDs were 2.46 for pain intensity, 3.14 for number of painful body sites, and 4,997.60 for pain extent.

CONCLUSIONS

The vertical pain rating scale and the body chart seem reliable to assess pain intensity and number of pain sites, respectively. The wide CI for the ICC found for pain area and the high measurement error compromise its potential clinical relevance.

Frailty Status Typologies in Spanish Older Population: Associations with Successful Aging

Background: Defining frailty typologies would contribute to guiding specific care interventions. These typologies could additionally be related to different health outcomes. This study aims at identifying subgroups of frail older adults based on the physical frailty phenotype and examining the relationships of these frailty profiles with quality of life and perceived health. Methods: This study relies on data from the SHARE project, namely a representative sample of 1765 Spanish-dwelling older adults identified as frail or pre-frail. Analysis included general descriptive statistics, exploratory latent class analysis (LCA) to determine the number of frailty subgroups, and LCA with covariates to examine differential relationships with markers of successful aging. Results: Statistical criteria and interpretability of the classes suggested that the LCA model with four classes should be retained. Class 1 was identified as the “frail people” group, Class 2 “activity problems” group, Class 3 “fatigued” group, and those belonging to Class 4 “lack of strength” group. Final LCA with covariates showed lower levels of quality of life and perceived health of the “frail” as compared to other frailty subgroups. Conclusion: This study revealed four different patterns of frailty attributes and further offered evidence on individuals’ differential status of health regarding distinct frailty conditions.

Musculoskeletal Pain in Older Adults: A Clinical Review

Persistent pain in older adults is a widely prevalent and disabling condition that is the manifestation of multiple contributing physical, mental, social, and age-related factors. To effectively treat pain, the clinician must assess and address contributing factors using a comprehensive approach that includes pharmacologic and nonpharmacologic therapies within the context of a strong therapeutic relationship among the patient, caregivers, and a multidisciplinary team. This article reviews the current understanding of persistent pain in older adults and suggests a general approach to its assessment and management, followed by specific considerations for musculoskeletal pain conditions commonly seen in older adults.

Association between frailty and chronic pain among older adults: a systematic review and meta-analysis

PURPOSE

Frailty and chronic pain are prevalent among older adults. However, no study has systematically reviewed the association between frailty and chronic pain in older adults. Therefore, we aimed to estimate the prevalence of frailty and prefrailty among older adults with chronic pain and review the longitudinal association between frailty status and chronic pain.

METHODS

Embase, Medline, Pubmed, and Cochrane library were searched from inception to March 2020. The methodological quality of the studies was assessed using the Newcastle Ottawa Scale. Random effect models and Mantel-Haenszel weighting were adopted to synthesize the estimates.

RESULTS

Among the initial 846 articles retrieved, 24 were included in the review (12 cross-sectional, and 12 longitudinal). The pooled prevalence in persons with chronic pain was 18% (95% CI 14-23%; I² = 98.7%) for frailty and 43% (95% CI 36-51%; I² = 98.2%) for prefrailty. The pooled prevalence of chronic pain was 50% (95% CI 45-55%; I² = 88.3%) for individuals with frailty and 37% (95% CI 31-42%; I² = 97.1%) for individuals with prefrailty. Persons with chronic pain were 1.85 (95% CI 1.49-2.28; I² = 93.2%) times more likely to develop frailty after an average follow-up of 5.8 years compared to those without.

CONCLUSION

Frailty and prefrailty are common in persons with chronic pain. Chronic pain among non-frail older persons significantly predicts the incidence of frailty after an average follow-up of 5.8 years. Future studies should explore the efficacy of different pain management strategies in reducing physical frailty and clarify the association of other types of frailty (cognitive, social and psychological) with chronic pain.

Association between chronic pain and pre-frailty in Japanese community-dwelling older adults: A cross-sectional study

A relationship between chronic pain and frailty has been reported. The early detection and prevention of frailty are recommended, in part because community-dwelling older adults in a pre-frailty state may return to a healthy state. The relationship between chronic pain and pre-frailty is not known. Toward the goal of promoting a reversible return to health from pre-frailty, we investigated the relationship between chronic pain and pre-frailty among community-dwelling older adults. We assessed the frailty and chronic pain of 107 older adults who were participating in community health checks. The status of physical frailty was based on the five components described by Fried (2001): muscle weakness shown by handgrip strength, slowness of gait speed, weight loss, low physical activity, and exhaustion. Chronic pain was assessed based on pain intensity, the Pain Catastrophizing Scale (PCS), the Japanese version of the Geriatric Depression Scale-15 (GDS-15), and the Central Sensitization Inventory (CSI). The prevalence of chronic pain with pre-frailty was 40.2%. A hierarchical analysis revealed that PCS-measured helplessness (odds ratio [OR]: 0.88) and the CSI (OR: 0.87) were significant factors associated with the presence of chronic pain with pre-frailty. The prevalence of chronic pain with pre-frailty was high, and chronic pain and pre-frailty were strongly related. New intervention or prevention programs that take into account both chronic pain and pre-frailty must be created as soon as possible.

Prevalence and Correlates of Frailty in Community-Dwelling Older Adults with Chronic Pain: A Cross-Sectional Study

BACKGROUND

Frailty is a frequent health condition in older adults of decreased functional reserve that leads to vulnerability to internal and external stressors. It has been associated with chronic pain, which is a common, costly and incapacitating condition in older adults.

AIMS

To describe frailty status in a sample of community-dwelling older adults with chronic pain attending a primary health care centre.

DESIGN

Cross-sectional investigation.

PARTICIPANTS

Adults aged 65 years or older with chronic pain.

METHODS

The Survey of Health, Ageing and Retirement in Europe Frailty Instrument (SHARE-FI) was used to assess frailty status and a visual analogue scale to assess pain intensity. Descriptive and analytical statistics were performed.

RESULTS

Among 154 participants recruited, 20.1% were frail, 38.3% pre-frail and 41.6% robust. Women were more likely to be classified as frail or pre-frail (OR: 4.62, 95% CI: 2.23-9.59), as well as participants aged 75 years or older (OR: 3.41, 95% CI: 1.74-6.68) and participants reporting moderate and severe pain (OR: 4.20, 95% CI: 2.10-8.40). These results remained significant after adjustment.

CONCLUSIONS

There is an association between frailty status and other variables such as older age, female gender and higher pain intensity.

Persistent, Consistent, and Extensive: The Trend of Increasing Pain Prevalence in Older Americans

OBJECTIVES

Assess trends in pain prevalence from 1992 to 2014 among older U.S. adults and by major population subgroups, and test whether the trends can be explained by changes in population composition.

METHODS

Health and Retirement Study data include information on any pain, pain intensity, and limitations in usual activities due to pain. Average annual percent change in prevalence is calculated for any and for 2 levels of pain-mild/moderate and nonlimiting and severe and/or limiting-across demographic and socioeconomic characteristics, and for those with and without specific chronic conditions. Generalized linear latent and mixed models examine trends adjusting for covariates.

RESULTS

Linear and extensive increases in pain prevalence occurred across the total population and subgroups. The average annual percent increase was in the 2%-3% range depending upon age and sex. Increases were consistent across subgroups, persistent over time, and not due to changes in population composition. Without increases in educational attainment over time, pain prevalence increases would be even higher.

DISCUSSION

The increases in pain prevalence among older Americans are alarming and potentially of epidemic proportions. Population-health research must monitor and understand these worrisome trends.

Linking Persistent Pain and Frailty in Older Adults

OBJECTIVE

In older adults, the impact of persistent pain goes beyond simple discomfort, often contributing to worsening functional outcomes and ultimately frailty. Frailty is a geriatric syndrome that, like persistent pain, increases in prevalence with age and is characterized by a decreased ability to adapt to common stressors such as acute illness, thereby increasing risk for multiple adverse health outcomes. Evidence supports a relationship between persistent pain and both the incidence and progression of frailty, independent of health, social, and lifestyle confounders.

DESIGN AND SETTING

In this article, we synthesize recent evidence linking persistent pain and frailty in an effort to clarify the nature of the relationship between these two commonly occurring geriatric syndromes.

SETTING

We propose an integration of the frailty phenotype model by considering the impact of persistent pain on vulnerability toward external stressors, which can ultimately contribute to frailty in older adults.

RESULTS AND CONCLUSIONS

Incorporating persistent pain into the frailty construct can help us better understand frailty and ultimately improve care for patients with, as well as those at increased risk for, pain and frailty.

A Biopsychosocial Model of Chronic Pain for Older Adults

Population

Comprehensive evaluation of chronic pain in older adults is multifaceted.

Objective and Methods

Research on chronic pain in older adults needs to be guided by sound conceptual models. The purpose of this paper is to describe an adaptation of the Biopsychosocial Model (BPS) of Chronic Pain for older adults. The extant literature was reviewed, and selected research findings that provide the empiric foundation for this adaptation of the BPS model of chronic pain are summarized. The paper concludes with a discussion of specific recommendations for how this adapted model can be used to guide future research.

Conclusions

This adaptation of the BPS model of chronic pain for older adults provides a comprehensive framework to guide future research in this vulnerable population.

Chronic Pain and Frailty in Community-Dwelling Older Adults: A Systematic Review

OBJECTIVE

Our aim was to examine the relationship between chronic pain and frailty in community-dwelling older adults.

DESIGN

A systematic review method following the Joanna Briggs Institute Reviewers' Manual 2015.

DATA SOURCES

MEDLINE, Cochrane Library Plus, Science Direct, Scielo, LILACS, and the Joanna Briggs Institute database of systematic reviews and implementation reports were searched using different combinations of the terms "frail," "frailty," and "pain."

REVIEW/ANALYSIS METHODS

Original publications of nononcologic chronic pain and frailty status in community-dwelling older adults published in English or Spanish were included. Because of the heterogeneity of the studies, a narrative approach was used to summarize the results.

RESULTS

A total of 23 studies were finally selected for the systematic review. Most of them (n = 14) were cross-sectional studies, and there were also longitudinal studies (n = 4), cohort studies (n = 3), and randomized controlled trials (n = 2). Most of the studies found an association between chronic pain and frailty in terms of prevalence; approximately 45% of frail patients had chronic pain, and prevalence can reach 70%.

CONCLUSIONS

The studies analyzed suggest that chronic pain has a predictive effect for frailty in older adults compared with those reporting no pain. Higher pain intensity, chronic widespread pain, and higher pain interference were also related to frailty status. No specific interventions for managing chronic pain in frail or prefrail older adults were found.

Frequency, intensity and localization of pain as risk factors for frailty in older adults

Background

the association between pain characteristics and frailty risk is uncertain.

Objective

to investigate the separate impact of the frequency, intensity and location of pain on frailty risk and its possible mechanisms.

Methods

prospective cohort of 1505 individuals ≥63 years followed between 2012 and 2015 in Spain. In 2012, pain was classified into: lowest pain (Score 0), middle pain (Score 1-4) and highest pain (Score 5-6). Incident frailty was assessed in 2015 as having ≥3 Fried criteria or a Frailty Index (FI) ≥0.30.

Results

in multivariate analyses, the risk of frailty (measured with the Fried criteria or the FI) increased progressively with the frequency of pain, its intensity and the number of pain locations. Compared with those having the lowest pain score, the odds ratio (95% confidence interval) of Fried-based frailty was 1.24 (0.56-2.75) in the middle score and 2.39 (1.34-4.27; P-trend <0.01) in the highest score. Corresponding values for frailty as FI ≥0.30 were 1.39 (0.80-2.42) and 2.77 (1.81-4.24; P-trend <0.01). Odds ratios did not change after adjustment for alcohol intake, Mediterranean diet adherence or sedentary time, but were reduced with adjustment for pain-associated chronic diseases (cardiovascular disease, diabetes, chronic lung disease, osteomuscular disease and depression). A higher pain score was linked to higher risk of exhaustion and low physical activity (two out of five Fried criteria) and to a worse score in all FI domains.

Conclusion

frequency, intensity and location of pain were associated with higher risk of frailty. Study associations were partly explained by pain-associated morbidity.

Persistent pain is a risk factor for frailty: a systematic review and meta-analysis from prospective longitudinal studies

Background

pain is prevalent in frail older adults; however, the association of pain and frailty has not been evaluated yet by a systematic assessment of prospective longitudinal studies.

Objective

we aimed to assess the association of persistent pain as a risk factor for frailty incidence, using data from longitudinal studies in a systematic review and meta-analysis.

Methods

publications were identified using a systematic search on PubMed, Embase, Cochrane Library and clinicaltrials.gov databases from inception to October 2017. Since heterogeneity across studies was high, we used random-effects meta-analysis to calculate the pooled relative risk for the association between persistent pain and the incidence of frailty. We investigated sources of heterogeneity among studies using meta-regression and stratified analyses.

Results

we included five prospective longitudinal studies with 13,120 participants (46% women, mean age from 59 to 85 years old). Participants with persistent pain at baseline had twice the risk of developing frailty during the follow-up (pooled RR = 2.22, 95% CI = 1.14-4.29). No variables were related to study heterogeneity in sensitivity analyses.

Conclusion

persistent pain was a risk factor for the development of frailty in a meta-analysis of longitudinal studies. Better understanding of the association between pain and frailty with proper evaluation of potential confounders could allow the development of targeted interventions.

Accounting for frailty when treating chronic diseases

Chronic diseases are considered to be major determinants of frailty and it could be hypothesized that their treatment may counteract the development of frailty. However, the hypothesis that intensive treatment of chronic diseases might reduce the progression of frailty is poorly supported by existing studies. In contrast, some evidence suggests that intensive treatment of chronic diseases may increase negative health outcomes in frail older adults. In particular, if treatment of symptoms related to chronic diseases (i.e. pain in osteoarthritis, dyspnoea in respiratory disease, motor symptoms in Parkinson disease) might potentially reverse frailty, the benefits related to preventive pharmacological treatment of chronic diseases (i.e. antihypertensive treatment) in patients with prevalent frailty is not certain. In particular, several factors might alter the risk/benefit ratio of a given treatment in persons with frailty. These include: exclusion of frail persons from clinical studies, reduced life expectancy in frail persons, increased susceptibility to iatrogenic events, and functional deficits associated with frailty. Therefore, frailty acts as an effect modifier, by modifying the risks and benefits of chronic disease treatments. This hypothesis must be considered and tested in future clinical intervention studies and clinical guidelines should provide specific recommendations for the treatment of frail people, underlining the pros and the cons of pharmacological treatment and possible targets for therapy in this population. Meanwhile, in older patients, the prescribing process should be individualized and flexible.

Chronic pain and geriatric syndromes in community-dwelling patients aged ≥65 years

Background

In growing elderly populations, there is a heavy burden of comorbidity and a high rate of geriatric syndromes (GS) including chronic pain.

Purpose

To assess the prevalence of chronic pain among individuals aged ≥65 years in the Southern District of Israel and to evaluate associations between chronic pain and other GS.

Methods

A telephone interview was conducted on a sample of older adults who live in the community. The interview included the Brief Pain Inventory and a questionnaire on common geriatric problems.

Results

Of 419 elderly individuals who agreed to be interviewed 232 (55.2%) suffered from chronic pain. Of those who reported chronic pain, 136 participants (68.6%) noted that they had very severe or unbearable pain. There were statistically significant associations between the pain itself and decline in patient’s functional status, increased falls, reduced mood, and cognitive decline.

Conclusion

The results of this study show that chronic pain is very common in older adults and that it is associated with other GS. There is a need to increase awareness of chronic pain in older adults and to emphasize the important role that it plays in their care.

Association between pain and the frailty phenotype in older men: longitudinal results from the Concord Health and Ageing in Men Project (CHAMP)

Objectives

to determine whether pain increases the risk of developing the frailty phenotype and whether frailty increases the risk of developing chronic or intrusive pain, using longitudinal data.

Design/Setting

longitudinal data from the Concord Health and Ageing in Men Project (CHAMP), a prospective population based cohort study.

Participants

a total of 1,705 men aged 70 years or older, living in an urban area of New South Wales, Australia.

Measurements

data on the presence of chronic pain (daily pain for at least 3 months), intrusive pain (pain causing moderate to severe interference with activities) and the criteria for the Cardiovascular Health Study (CHS) frailty phenotype were collected in three waves, from January 2005 to October 2013. Data on age, living arrangements, education, smoking status, alcohol consumption, body mass index, comorbidities, cognitive function, depressive symptoms and history of vertebral or hip fracture were also collected and included as covariates in the analyses.

Results

a total of 1,705 participants were included at baseline, of whom 1,332 provided data at the 2-year follow-up and 940 at the 5-year follow-up. Non-frail (robust and pre-frail) men who reported chronic pain were 1.60 (95% confidence interval (CI): 1.02-2.51, P = 0.039) times more likely to develop frailty at follow-up, compared to those with no pain. Intrusive pain did not significantly increase the risk of future frailty. Likewise, the frailty status was not associated with future chronic or intrusive pain in the adjusted analysis.

Conclusions

the presence of chronic pain increases the risk of developing the frailty phenotype in community-dwelling older men.

Impact of frailty on chronic pain, activities of daily living and physical activity in community-dwelling older adults: A cross-sectional study

AIM

The present cross-sectional study investigated the relationship between frailty and chronic pain, activities of daily living (ADL), and physical activity in community-dwelling older adults.

METHODS

Participants were 379 older adults who attended community-based exercise classes. Outcome measures were frailty as determined by the Kihon Checklist, full pain assessment (including the sensory, emotional and cognitive aspects of pain), ADL and physical activity. These outcomes were evaluated using validated tests and instruments. Assessments were carried out before beginning the exercise classes. Outcome measures were compared for participants with and without frailty. Frailty was defined as a total Kihon Checklist score ≥7, and chronic pain as the presence of related symptoms within the past month that had continued for at least 6 months and corresponded with a numerical rating scale score of at ≥5 at the site of maximum pain.

RESULTS

In total, 134 (35.4%) participants met the frailty criteria; 60.4% of this group had chronic pain. The frail group had significantly worse scores for the sensory, emotional and cognitive aspects of pain, ADL and physical activity than the non-frail group (P < 0.05). Logistic regression analysis adjusted for age and sex showed the sensory and emotional aspects of pain were associated with frailty.

CONCLUSIONS

For community-dwelling older adults with frailty, chronic pain can negatively influence sensory, emotional and cognitive aspects of pain, leading to a decline in ADL and lower physical activity. Full pain assessment focused on sensory and emotional aspects of pain is important to identify frailty among older adults. Geriatr Gerontol Int 2018; 18: 1079-1084.

Physical inactivity and cognitive impairment in Korean older adults: gender differences in potential covariates

BACKGROUND

Physical inactivity is one major lifestyle risk factor of mild cognitive impairment with ageing.

AIM

To investigate whether or not potential covariates modulate the association between physical activity (PA) and cognitive impairment in older adults.

SUBJECTS AND METHODS

Data from 10 245 Korean older adults (5817 women) were used.

RESULTS

High PA older adults were younger and longer educated and had lower comorbidity and depression than low PA older adults. Compared with low PA men, moderate PA men only had a significantly lower odds-ratio (OR) and 95% confidence interval (95% CI) (OR = 0.795, 95% CI = 0.654 ∼ 0.965, p = 0.021) for having cognitive impairment, even after adjusting for measured covariates, which was no longer significant when additionally adjusted for comorbidity (OR = 0.862, 95% CI = 0.707 ∼ 1.051, p = 0.143). Compared with low PA women, moderate and high PA women had significantly lower risks of cognitive impairment (OR = 0.830, 95% CI = 0.712 ∼ 0.969, p = 0.018 and OR = 0.784, 95% CI = 0.651 ∼ 0.943, p = 0.010, respectively), even after adjusting for the measured covariates including comorbidity, which was no longer significant when additionally adjusted for depression (OR = 0.897, 95% CI = 0.776 ∼ 1.049, p = 0.173 and OR = 0.919, 95% CI = 0.761 ∼ 1.111, p = 0.385, respectively).

CONCLUSION

These findings suggest that gender differences in the covariates modulate the relationship between physical activity and cognitive decline in older Korean adults.
