Musculoskeletal pain in older adults at the end-of-life: a systematic search and critical review of the literature with priorities for future research

Home Ultrasound: A Contemporary and Valuable Tool for Palliative Medicine

This narrative review explores the application of point-of-care ultrasound (POCUS) in palliative care and its feasibility in home care settings. POCUS has the potential to streamline diagnostic strategies without patient transfer to the hospital, expedite timely symptomatic relief, and reduce complications from specific palliative interventions. The advent of handheld ultrasound devices has made it an attractive diagnostic and interventional adjunct in acute palliative care. POCUS has gained widespread acceptance as part of routine care in emergency medicine and intensive care, guiding certain procedures and increasing their safety. The modernization and miniaturization of ultrasound equipment have made ultra-portable devices available, allowing for better-quality images at affordable prices. Handheld devices have the potential to revolutionize everyday clinical practice in home-based palliative care, contributing to important bedside clinical decisions. Palliative care patients often require diagnostic examinations in the last months of their lives, with CT being the most frequently performed imaging procedure. However, CT imaging is associated with high costs and burdens, leading to increased suffering and impaired quality of life. Clinical ultrasound, a dialogic imaging modality, offers a safer and more efficient approach to palliative care. POCUS applications, which are cost-effective, non-invasive, and well-tolerated, can be used to improve patient satisfaction and diagnostic understanding. POCUS is a valuable tool in palliative care, improving diagnostic accuracy and reducing the time to diagnosis for various pathologies. It is a standard of care for many procedures and improves patient safety. However, there are limitations to POCUS in palliative care, such as operator-dependent examination variability and limited availability of trained professionals. To overcome these limitations, palliative care physicians should receive mandatory training in POCUS, which can be incorporated into the core curriculum. Additionally, ultrasound teleconsulting can assist less experienced examiners in real-time examinations. The literature on POCUS in palliative care is limited, but research on patient-oriented outcomes is crucial. POCUS should be considered a supplement to good clinical reasoning and regulated radiological evaluations.

Development, refinement, and validation of an equine musculoskeletal pain scale

Musculoskeletal disease is a common cause of chronic pain that is often overlooked and inadequately treated, impacting the quality of life of humans and horses alike. Lameness due to musculoskeletal pain is prevalent in horses, but the perception of pain by owners is low compared with veterinary diagnosis. Therefore, this study aims to establish and validate a pain scale for chronic equine orthopaedic pain that is user-friendly for horse owners and veterinarians to facilitate the identification and monitoring of pain in horses. The newly developed musculoskeletal pain scale (MPS) was applied to 154 horses (mean age 20 ± 6.4 years SD) housed at an equine sanctuary, of which 128 (83%) suffered from chronic orthopaedic disease. To complete the MPS, the horses were observed and videotaped from a distance while at rest in their box or enclosure. In addition, they received a complete clinical and orthopaedic exam. The need for veterinary intervention to address pain (assessed and executed by the sanctuary independent from this study) was used as a longitudinal health outcome to determine the MPS's predictive validity. To determine the interrater agreement, the MPS was scored for a randomly selected subset of 30 horses by six additional blinded raters, three equine veterinary practitioners, and three experienced equestrians. An iterative process was used to refine the tool based on improvements in the MPS's correlation with lameness evaluated at the walk and trot, predictive validity for longitudinal health outcomes, and interrater agreement. The intraclass correlation improved from 0.77 of the original MPS to 0.88 of the refined version (95% confidence interval: 0.8-0.94). The refined MPS correlated significantly with lameness at the walk (r = 0.44, p = 0.001) and trot (r = 0.5, p < 0.0001). The refined MPS significantly differed between horses that needed veterinary intervention (mean MPS = 8.6) and those that did not (mean MPS = 5.0, p = 0.0007). In summary, the MPS showed good interrater repeatability between expert and lay scorers, significant correlation with lameness at the walk and trot, and good predictive validity for longitudinal health outcomes, confirming its ability to identify horses with orthopaedic health problems.

Overcoming Barriers to the Implementation of Integrated Musculoskeletal Pain Management Programs: A Multi-Stakeholder Qualitative Study

Integrated pain management (IPM) programs can help to reduce the substantial population health burden of musculoskeletal pain, but are poorly implemented. Lessons learned from existing programs can inform efforts to expand IPM implementation. This qualitative study describes how health care systems, payers, providers, health policy researchers, and other stakeholders are overcoming barriers to developing and sustaining IPM programs in real-world settings. Primary data were collected February 2020 through September 2021 from a multi-sector expert panel of 25 stakeholders, 53 expert interviews representing 30 distinct IPM programs across the United States, and 4 original case studies of exemplar IPM programs. We use a consensual team-based approach to systematically analyze qualitative findings. We identified 4 major themes around challenges and potential solutions for implementing IPM programs: navigating coverage, payment, and reimbursement; enacting organizational change; making a business case to stakeholders; and overcoming regulatory hurdles. Strategies to address payment challenges included use of group visits, linked visits between billable and nonbillable providers, and development of value-based payment models. Organizational change strategies included engagement of clinical and administrative champions and co-location of services. Business case strategies involved demonstrating the ability to initially break even and potential to reduce downstream costs, while improving nonfinancial outcomes like patient satisfaction and provider burnout. Regulatory hurdles were overcome with innovative credentialing methods by leveraging available waivers and managed care contracting to expand access to IPM services. Lessons from existing programs provide direction on to grow and support such IPM delivery models across a variety of settings. PERSPECTIVE: Integrated pain management (IPM) programs face numerous implementation challenges related to payment, organizational change, care coordination, and regulatory requirements. Drawing on real-world experiences of existing programs and from diverse IPM stakeholders, we outline actionable strategies that health care systems, providers, and payers can use to expand implementation of these programs.

Prognosis does not change the landscape: palliative home care clients experience high rates of pain and nausea, regardless of prognosis

BACKGROUND

Most individuals who typically receive palliative care (PC) tend to have cancer and a relatively short prognosis (< 6 months). People with other life-limiting illnesses can also benefit from a palliative care approach. However, little is known about those who receive palliative home care in Ontario, Canada's largest province. To address this gap, the goal of this project was to understand the needs, symptoms and potential differences between those with a shorter (< 6 months) and longer prognosis (6+ months) for individuals receiving PC in the community.

METHODS

A cross-sectional analysis was conducted using interRAI Palliative Care (interRAI PC) assessment data collected between 2011 and 2018. Individuals with a shorter prognosis (< 6 months; n = 48,019 or 64.1%) were compared to those with a longer prognosis (6+ months; n = 26,945) across several clinical symptoms. The standardized difference (stdiff), between proportions, was calculated to identify statistically meaningful differences between those with a shorter and longer prognosis. Values of the stdiff of 0.2 or higher (absolute value) indicated a statistically significant difference.

RESULTS

Overall, cancer was the most prevalent diagnosis (83.2%). Those with a shorter prognosis were significantly more likely to experience fatigue (75.3% vs. 59.5%; stdiff = 0.34) and shortness of breath at rest (22.1% vs. 13.4%; stdiff = 0.23). However, the two groups were similar in terms of severe pain (73.5% vs. 66.5%; stdiff = - 0.15), depressive symptoms (13.2% vs. 10.7%; stdiff = 0.08) and nausea (35.7% vs. 29.4%; stdiff = 0.13).

CONCLUSIONS

These results highlight the importance of earlier identification of individuals who could benefit from a palliative approach to their care as individuals with a longer prognosis also experience high rates of symptoms such as pain and nausea. Providing PC earlier in the illness trajectory has the potential to improve an individual's overall quality of life throughout the duration of their illness.

Pain as a predictor of frailty over time among older Mexican Americans

The objective of this study was to examine pain as a predictor of frailty over 18 years of follow-up among older Mexican Americans who were nonfrail at baseline. Data were from a prospective cohort study of 1545 community-dwelling Mexican Americans aged ≥67 years from the Hispanic Established Populations for the Epidemiological Study of the Elderly (1995/1996-2012/2013). Frailty was defined as meeting 2 or more of the following: unintentional weight loss of >10 pounds, weakness, self-reported exhaustion, and slowness. The independent predictor was self-reported pain. Covariates included age, sex, marital status, education, comorbid conditions, body mass index, Mini-Mental State Examination, depressive symptoms, and limitation in activities of daily livings. General equation estimation was performed to estimate the odds ratio of frailty as a function of pain. A total of 538 participants (34.8%) reported pain at baseline. The prevalence of frailty among those with pain ranged from 24.4% in wave 3 to 41% in wave 8. The odds ratio of becoming frail over time as a function of pain was 1.71; 95% confidence interval: 1.41 to 2.09 after controlling for all covariates. Older age, hip fracture, high depressive symptoms, and activities of daily living disability were also associated with higher odds of becoming frail over time. Female participants and those with higher levels of education and high Mini-Mental State Examination scores were less at risk. In conclusion, pain was a significantly predictor of frailty. Early assessment and better management of pain may prevent early onset of frailty in older Mexican Americans.

Point of care ultrasound for rapid assessment and treatment of palliative care patients in acute medical settings

The combination of an ageing population with improving survival in malignant and non-malignant disease processes results in a growing cohort of patients with advanced or end-stage chronic diseases who require acute medical care. Emergency care has historically been stereotyped as the identification and treatment of acute life-threatening problems. Although palliative care may be considered to be new to the formal curriculum of emergency medicine, in many domains the ultrasound skillset of a physician in acute medical care can be efficaciously deployed the benefit of patients with both malignant and non-malignant disease processes that require palliative care in the full breadth of acute healthcare settings. In diagnostic domains (abdominal pain, urinary tract obstruction, dyspnoea, venous thromboembolism and musculoskeletal pain) and for specific intervention guidance (thoracentesis, paracentesis, venous access, regional anaesthesia and musculoskeletal interventions) we suggest that POCUS has the potential to streamline improve patient satisfaction, streamline diagnostic strategies, optimise patient length of stay, expedite timely symptomatic relief and reduce complications in this important patient population. POCUS is a mandatory competence in the European curriculum of internal medicine, and specific training programs which cover applications in the domains of palliative care in acute care settings are available. Supervision, quality assurance and appropriate documentation are required. We expect that as the availability of mobile units suitable for point of care applications increases, these applications should become standard of care in the acute management of patients who require palliative care.

The Intersection of Oncology Prognosis and Cancer Rehabilitation

PURPOSE OF REVIEW

This review examines the delivery of rehabilitation care to cancer patients with relation to disease prognosis. This includes the evaluation when patients are referred for rehabilitation services and the effectiveness of rehabilitation interventions across the cancer continuum.

RECENT FINDINGS

Although prognosticating life expectancy is difficult, referrals for rehabilitation interventions appear to be affected by physician attitudes towards patients with advanced disease, in part because of misconceptions about the nature of rehabilitation for oncology patients. Rehabilitation may also be underutilized in long-term survivors with no evidence of disease. Despite this, our review found that rehabilitation in advanced disease, end-of-life, geriatric cancer patients, and in long-term survivors can be beneficial. There is a relative dearth in studies on rehabilitation interventions specifically at the end-of-life.

SUMMARY

Cancer rehabilitation can be helpful to patients along the spectrum of cancer prognoses. Examining more accurate ways to prognosticate life expectancy, improving communication and education between oncologists and rehabilitation team members, and modifying survivorship plans to include patient education on functional changes over time may improve the delivery of rehabilitation care.

The Use of Ultrasound in Palliative Care and Hospice

Palliative care aims to reduce symptom burden and enhance quality of life for those with terminal disease. Ultrasound has become an increasingly popular diagnostic and therapeutic modality due to its low cost, ease of portability, safety, and good patient acceptance. A review of the literature to date shows that as a diagnostic tool, as a therapeutic modality, and as a tool to accurately guide palliative procedures, ultrasound can have many roles in palliative care and hospice. Based on our clinical experience, musculoskeletal ultrasound can be of benefit to patients with terminal disease. Examples include adhesive capsulitis in advanced neurologic disease and chronic osteomyelitis in a patient with metastatic colon cancer. Ideally, further studies investigating the use of ultrasound in the palliative care population will be conducted in the future to enhance the availability of diagnostic and therapeutic capabilities of this particular modality.

Building a Biopsychosocial Conceptual Framework to Explore Pressure Ulcer Pain for Hospitalized Patients

Although pressure ulcers are a prevalent condition, pain associated with pressure ulcers is not fully understood. Indeed, previous studies do not shed light on the association between pressure ulcer stages and the experience of pain. Especially, pain characteristics of suspected deep tissue injury, which is a new category that was recently added by the National Pressure Ulcer Advisory Panel, are yet unknown. This is concerning because the incidence of pressure ulcers in hospitalized patients has increased exponentially over the last two decades, and health care providers are struggling to ensure providing adequate care. Thus, in order to facilitate the development of effective interventions, this paper presents a conceptual framework to explore pressure ulcer pain in hospitalized patients. The concepts were derived from a biopsychosocial model of pain, and the relationships among each concept were identified through a literature review. Major propositions are presented based on the proposed conceptual framework, which integrates previous research on pressure ulcer pain, to ultimately improve understanding of pain in hospitalized patients with pressure ulcers.

The Effect of Age and Gender on Pressure Pain Thresholds and Suprathreshold Stimuli

Objectives:

The study investigates the impact of age and gender on (1) experimental pressure pain detection thresholds (PPDT) and pressure pain tolerance thresholds (PPTolT) and (2) participants' self-reports of pain intensity and unpleasantness at suprathreshold and subthreshold levels.

Methods:

twenty young (20–34, mean age = 24.6 ± 3.6 years, ten female) and twenty elderly (65–88, mean age = 73.6 ± 6.6 years, ten female) healthy volunteers were compared. Mini-Mental State Examination (MMSE 28–30) assessed intact cognitive functioning. Pain thresholds were assessed together with the sensory intensity ratings to 1.3 x PPDT (pain) and 0.2 x PPDT (no pain).

Results:

PPDT and PPTolT significantly decreased with age and were lower in young females as compared with young males. No gender differences were observed in the elderly group. PPDT decreased significantly with age in males but not in females. Conversely, the intensity and unpleasantness of the pain stimulus were significantly rated lower in the elderly as compared with the young. No gender differences were observed in the report of intensity and unpleasantness of the stimulations.

Discussion:

a mismatch in pain sensitivity, tolerance, and pain self-reports was observed. Findings suggest that pain experiences in the elderly differ from the experiences in the young on multiple dimensions: sensory, affective, and cognitive. Findings may also indicate that the elderly appraise pain experiences using different psychological strategies.
