Self- and Carer-Rated Pain in People With Dementia: Influences of Pain in Carers

Physical pain among family caregivers to older adults: A scoping review of the literature

BACKGROUND AND OBJECTIVES

Scholarship on the health of family caregivers to older adults continues to expand. Although existing research suggests that many family caregivers experience pain, which impacts their ability to perform caregiving tasks and is associated with care recipients' unmet needs, the scope of research on family caregivers' pain remains poorly characterized. We conducted a scoping review of research on pain among family caregivers to older adults to characterize existing evidence and identify knowledge gaps.

METHODS

We searched multiple databases spanning from January 2012 to July 2023, identified eligible studies using predefined inclusion/exclusion criteria, and extracted key data (e.g., study design/methodology, pain measurement, caregiver pain type, and major findings).

RESULTS

We identified 46 eligible studies conducted in the United States (n = 19) and internationally (n = 27). Studies often focused on caregivers for older adults with specific health conditions, such as cancer (n = 11), dementia (n = 8), or stroke (n = 3). The most commonly employed pain measure was a single-item dichotomous question about pain (n = 16), followed by a visual numeric or visual analog scale (n = 11). Nine studies (five randomized controlled trials) reported on five caregiver pain management interventions, including yoga/exercise programs and caregiver education programs.

DISCUSSION

Existing research on family caregivers' pain offers an important foundation. However, more robust research designs are necessary. We identify possibilities for future studies in addition to opportunities for systematic investigations to support the family caregivers being relied upon to care for the increasing number of older adults.

Factors influencing the psychosocial well-being of people with dementia and their informal caregivers: A systematic review of dyadic studies

Individuals with dementia and their informal caregivers face significant challenges to their psychosocial well-being, necessitating immediate attention. In spite of the prevalence of this problem, there is limited data regarding the factors that influence the dyadic psychosocial well-being and potential actor-partner influencing mechanisms. Therefore, this review was conducted to synthesise the factors associated with the psychosocial well-being of people with dementia and their informal caregivers. MEDLINE via EBSCOhost, CINAHL, PsycINFO, Embase and Scopus were systematically searched to identify relevant studies. Quantitative, qualitative or mixed-method studies examining the factors influencing dyadic psychosocial well-being outcomes were included. The quality of included studies was assessed using Joanna Briggs Institute Critical Appraisal checklists. A narrative synthesis approach was employed for data analysis. A total of 3217 records were yield, out of which 26 studies were included in the analysis. Quality of life emerged as the most extensively investigated dyadic psychosocial well-being outcome, followed by depression. The interrelation between the quality of life for people with dementia and caregivers was observed, where individual members' quality of life was influenced by their own, partner and dyadic factors. However, there is a dearth of research exploring the mechanisms through which one member's factors exert influence on both their own and partner's quality of life within the dyad. This gap also exists for other psychosocial well-being outcomes, such as depression and anxiety. Further research is warranted to elucidate the underlying mechanisms through which dyadic members influence their own and their partner's psychosocial well-being.

Mechanisms of pain in aging and age-related conditions: Focus on caregivers

Pain is a complex, subjective experience that can significantly impact quality of life, particularly in aging individuals, by adversely affecting physical and emotional well-being. Whereas acute pain usually serves a protective function, chronic pain is a persistent pathological condition that contributes to functional deficits, cognitive decline, and emotional disturbances in the elderly. Despite substantial progress that has been made in characterizing age-related changes in pain, complete mechanistic details of pain processing mechanisms in the aging patient remain unknown. Pain is particularly under-recognized and under-managed in the elderly, especially among patients with Alzheimer's disease (AD), Alzheimer's disease-related dementias (ADRD), and other age-related conditions. Furthermore, difficulties in assessing pain in patients with AD/ADRD and other age-related conditions may contribute to the familial caregiver burden. The purpose of this article is to discuss the mechanisms and risk factors for chronic pain development and persistence, with a particular focus on age-related changes. Our article also highlights the importance of caregivers working with aging chronic pain patients, and emphasizes the urgent need for increased legislative awareness and improved pain management in these populations to substantially alleviate caregiver burden.

The challenge of pain identification, assessment, and management in people with dementia: a qualitative study

BACKGROUND

Painful conditions are common in older adults, including people with dementia. The symptoms associated with dementia (for example, diminished language capacity, memory impairment, and behavioural changes), however, may lead to the suboptimal identification, assessment, and management of pain. Research has yet to qualitatively explore pain management for community-dwelling people with dementia.

AIM

To explore pain identification, assessment, and management for community-dwelling people with dementia.

DESIGN & SETTING

A qualitative study was undertaken, set in England.

METHOD

Semi-structured interviews took place with people with dementia, family caregivers, GPs, and old-age psychiatrists. Data were analysed thematically.

RESULTS

Interviews were conducted with eight people with dementia, nine family caregivers, nine GPs, and five old-age psychiatrists. Three themes were identified that related to pain identification and assessment: gathering information to identify pain; the importance of knowing the person; and the use of pain assessment tools. A further three themes were identified that related to pain management: non-drug strategies; concerns related to analgesic medications; and responsibility of the caregiver to manage pain.

CONCLUSION

Identifying and assessing the pain experienced by people with dementia was challenging. Most people with dementia, family caregivers, and healthcare professionals supported non-drug strategies to manage pain. The minimal concerns associated with non-drug strategies contrasted the multifactorial concerns associated with analgesic treatment for people with dementia. Given the complexity of pain identification, assessment, and management, primary care should work together with family caregivers and community services, with case finding for pain being considered in all assessment and management plans.

Patient Versus Informal Caregiver Proxy Reports of Pain Interference in Persons With Dementia

Objectives: Pain assessment and treatment is challenging among persons with dementia (PWDs). To better understand reports of pain interference, we examined ratings made by PWDs, as well as corresponding ratings about PWDs, as reported by the caregiver. We aimed to assess alignment between and predictors of caregiver and PWD report of pain interference. Methods: The sample consisted of 203 veterans with pain and mild to moderately severe dementia and an informal caregiver. Results: Most PWDs and their caregivers reported at least some pain interference and similar levels of pain interference. PWDs with greater cognitive impairment reported less pain interference, whereas caregivers who perceived the PWD to have greater depression reported more pain interference. Conclusions: PWD and caregiver characteristics were differentially associated with PWD versus caregiver report of pain interference. Results suggest the importance of caregiver reports to inform assessment, as well as factors complicating assessment. Pain in Dementia As one ages, the risk of developing both dementia and pain increases substantially (Scherder et al., 2009). It is estimated that 30% to 50% of persons with dementia (PWDs) experience persistent pain, a complex multifactor problem (Corbett et al., 2014). Despite the high prevalence of pain among older adults with dementia, and major advances in pain management, pain often remains unrecognized or undertreated (Hodgson et al., 2014).

Pain assessment and pain treatment for community-dwelling people with dementia: A systematic review and narrative synthesis

OBJECTIVES

To describe the current literature on pain assessment and pain treatment for community-dwelling people with dementia.

METHOD

A comprehensive systematic search of the literature with narrative synthesis was conducted. Eight major bibliographic databases were searched in October 2018. Titles, abstracts, and full-text articles were sequentially screened. Standardised data extraction and quality appraisal exercises were conducted.

RESULTS

Thirty-two studies were included in the review, 11 reporting findings on pain assessment tools or methods and 27 reporting findings on treatments for pain. In regard to pain assessment, a large proportion of people with moderate to severe dementia were unable to complete a self-report pain instrument. Pain was more commonly reported by informal caregivers than the person with dementia themselves. Limited evidence was available for pain-focused behavioural observation assessment. In regard to pain treatment, paracetamol use was more common in community-dwelling people with dementia compared with people without dementia. However, non-steroidal anti-inflammatory drugs (NSAIDs) were used less. For stronger analgesics, community-dwelling people with dementia were more likely to receive strong opioids (eg, fentanyl) than people without dementia.

CONCLUSION

This review identifies a dearth of high-quality studies exploring pain assessment and/or treatment for community-dwelling people with dementia, not least into non-pharmacological interventions. The consequences of this lack of evidence, given the current and projected prevalence of the disease, are very serious and require urgent redress. In the meantime, clinicians should adopt a patient- and caregiver-centred, multi-dimensional, longitudinal approach to pain assessment and pain treatment for this population.

Prevalence of pain-related diagnoses in patients with dementia: a nationwide study

Purposes

To investigate the prevalence of pain-related diagnoses in patients with dementia and evaluate the association of pain-related diagnoses with demographic characteristics and dementia subtypes.

Patients and methods

In this population-based retrospective cohort study, participants were recruited from a cohort of 2 million people randomly sampled from the general population in the National Health Insurance Research Database of Taiwan from 2000 to 2013. The index year was defined as the period of 1 year from the date of the first diagnosis of dementia.

Results

The study group comprised 28,450 patients with the dementia subtypes of vascular dementia, Alzheimer’s disease, or other dementia subtypes. The mean age of patients with dementia was 76.75 years. Of all patients with dementia, 49.07% had at least one pain-related diagnosis documented in their outpatient or inpatient claim records within the index year. The top three pain-related diagnoses were osteoarthritis (29.27%), headache (12.53%), and osteoporosis (11.43%). Musculoskeletal diagnosis was more likely in female patients with vascular dementia. Although patients with vascular dementia had a significantly lower prevalence of pain-related diagnosis, they had a significantly higher risk of 1-year mortality than patients with other dementia subtypes.

Conclusion

During the index year, 49.07% of patients with dementia had at least one pain-related diagnosis. To investigate the differences of the use of pain medication in patients with different dementia subtypes and the difference of pain-related diagnosis and treatment in patients with and without dementia, future studies are recommended.

Acute hospital dementia care: results from a national audit

BACKGROUND

Admission to an acute hospital can be distressing and disorientating for a person with dementia, and is associated with decline in cognitive and functional ability. The objective of this audit was to assess the quality of dementia care in acute hospitals in the Republic of Ireland.

METHODS

Across all 35 acute public hospitals, data was collected on care from admission through discharge using a retrospective chart review (n = 660), hospital organisation interview with senior management (n = 35), and ward level organisation interview with ward managers (n = 76). Inclusion criteria included a diagnosis of dementia, and a length of stay greater than 5 days.

RESULTS

Most patients received physical assessments, including mobility (89 %), continence (84 %) and pressure sore risk (87 %); however assessment of pain (75 %), and particularly functioning (36 %) was poor. Assessment for cognition (43 %) and delirium (30 %) was inadequate. Most wards have access at least 5 days per week to Liaison Psychiatry (93 %), Geriatric Medicine (84 %), Occupational Therapy (79 %), Speech & Language (81 %), Physiotherapy (99 %), and Palliative Care (89 %) Access to Psychology (9 %), Social Work (53 %), and Continence services (34 %) is limited. Dementia awareness training is provided on induction in only 2 hospitals, and almost half of hospitals did not offer dementia training to doctors (45 %) or nurses (48 %) in the previous 12 months. Staff cover could not be provided on 62 % of wards for attending dementia training. Most wards (84 %) had no dementia champion to guide best practice in care. Discharge planning was not initiated within 24 h of admission in 72 % of cases, less than 40 % had a single plan for discharge recorded, and 33 % of carers received no needs assessment prior to discharge. Length of stay was significantly greater for new discharges to residential care (p < .001).

CONCLUSION

Dementia care relating to assessment, access to certain specialist services, staffing levels, training and support, and discharge planning is sub-optimal, which may increase the risk of adverse patient outcomes and the cost of acute care. Areas of good practice are also highlighted.
