Who Suffers Most? Dementia and Pain in Nursing Home Patients: A Cross-sectional Study

The effect of a music-based caregiving intervention on pain intensity in nursing home patients with dementia: a cluster-randomized controlled study

ABSTRACT

Treatment of chronic pain in patients with dementia is challenging because they have reduced ability to report pain and are particularly vulnerable to side effects of analgesics. Different types of music-based therapy have been recommended and are used as an alternative to analgesics, but the evidence is lacking. Therefore, we performed a cluster-randomized controlled study (RCT) to reduce pain intensity using music-based caregiving (MBC) over 8 weeks in nursing home patients with dementia and chronic pain. We also investigated if the amount of MBC and different chronic pain syndromes would impact on the effect. Of the 645 patients, 498 patients from 36 wards in 12 nursing homes were screened for dementia and pain. Using the Clinical Dementia Rating Scale and the Mobilization-Observation-Behavior-Intensity-Dementia Pain Scale (range 0-10), 279 (71% females, 42% severe dementia) nursing home patients were randomized to intervention group (n = 134, 18 wards) or control group (n = 145, 18 wards). The main outcome was change in pain intensity before and after the intervention. The study did not reveal any effect of MBC on pain intensity when compared with the control group (B = -0.15, 95% CI [-0.72 to 0.43]). No significant difference was found within the intervention group analyzing the impact of intervention time (B = 0.73, 95% CI [-0.55 to 2.02]) or chronic primary vs secondary pain syndromes (B = 0.45, 95% CI [-0.05 to 0.96]). Our data from this first RCT on music and pain intensity in patients with dementia and chronic pain did not find an effect of MBC on pain.

Impact of Pain and Neuropsychiatric Symptoms on Activities in Nursing Home Residents (COSMOS Trial)

OBJECTIVE

This study aims to identify whether pain and dementia-related behavior are associated with different types of activities in nursing home residents, controlled for dementia severity.

DESIGN

Cross-sectional baseline data from the multicomponent cluster randomized controlled COSMOS trial (acronym for Communication, Systematic pain treatment, Medication review, Organization of activities, and Safety).

SETTING AND PARTICIPANTS

A total of 723 patients from 33 Norwegian nursing homes with 67 units (clusters). Participants aged ≥65 years, with a life expectancy of >6 months, and with valid data on activity were eligible for inclusion.

METHODS

Activity was operationalized in time (hours per week) and type (cognitive, social, physical, and no activity). Cognitive function was assessed using the Mini-Mental State Examination (MMSE), pain with the Mobilization-Observation-Behavior-Intensity-Dementia-2 Pain Scale (MOBID-2), and behavior with the Neuropsychiatric Inventory Nursing Home version (NPI-NH). Analyses were performed using linear and logistic regression. Sensitivity analyses for dementia severity were performed to account for effect modification.

RESULTS

A total of 289 participants were included (mean age 86.2 [SD 7.6]; 74% female). A higher pain score was associated with less time spent on activity in participants with severe dementia (estimate 0.897, P = .043). A higher score for the NPI-NH mood cluster (depression and anxiety) was associated with a higher likelihood of participation in cognitive activities (odds ratio [OR], 1.073; P = .039). Apathy (OR, 0.884; P = .041) and lack of inhibition (OR, 0.904; P = .042) were associated with a lower likelihood of participation in social activities as well as no engagement in activities (apathy OR, 0.880; P = .042; lack of inhibition OR, 0.894; P = .034).

CONCLUSION AND IMPLICATIONS

Pain and dementia-related behavior may influence the participation in activities in the nursing home. There is an urgent need to investigate what type of activity stimulates people in different stages of dementia.

The association between cognitive ability and opioid prescribing in vulnerable older adults with chronic pain in ambulatory care: a secondary data analysis using the Medical Expenditure Panel Survey

BACKGROUND

Vulnerable older adults living with Alzheimer's disease or Alzheimer's disease and related dementia (AD/ADRD) and chronic pain generally receive fewer pain medications than individuals without AD/ADRD, especially in nursing homes. Little is known about pain management in older adults with AD/ADRD in the community. The aim of the study was to examine opioid prescribing patterns in individuals with chronic pain by levels of cognitive ability in ambulatory care.

METHODS

We used the Medical Expenditure Panel Survey (MEPS), years 2002-2017, and identified three levels of cognitive impairment: no cognitive impairment (NCI), individuals reporting cognitive impairment (CI) without an AD/ADRD diagnosis, and individuals with a diagnosis of AD/ADRD. We examined any receipt of an opioid prescription and the number of opioid prescriptions using a logistic and negative binomial regression adjusting for sociodemographic and health characteristics and stratifying by three types of chronic pain (any chronic pain, severe chronic pain, and chronic pain identified through ICD 9/10 chronic pain diagnoses).

RESULTS

Among people with any chronic pain, adjusted odds of receiving an opioid for people with CI (OR 1.41, 95% confidence interval 1.31-1.52) and AD/ADRD (OR 1.23, 95% confidence interval 1.04-1.45) were higher compared to NCI. Among people with chronic pain ICD 9/10 conditions, the odds of receiving an opioid were also higher for those with CI (OR 1.43, 95% confidence interval 1.34-1.56) and AD/ADRD (OR 1.48, 95% confidence interval 1.23-1.78) compared to NCI. Among those with severe chronic pain, people with CI were more likely to receive an opioid (OR 1.17, 95% confidence interval 1.07-1.27) relative to NCI (OR 0.89, 95% confidence interval 0.75-1.06). People with AD/ADRD experiencing severe chronic pain were not more likely to receive an opioid compared to the NCI group. Adjusted predicted counts of opioid prescriptions showed more opioids in CI and AD/ADRD in all chronic pain cohorts, with the largest numbers of opioid prescriptions in the severe chronic pain and ICD 9/10 diagnoses groups.

CONCLUSIONS

The results suggest increased opioid use in people living with CI and AD/ADRD in the ambulatory care setting and potentially indicate that these individuals either require more analgesics or that opioids may be overprescribed. Further research is needed to examine pain management in this vulnerable population.

A systematic review of prevalence of pain in nursing home residents with dementia

BACKGROUND

The prevalence of dementia in nursing home (NH) residents is high, and pain is a troublesome symptom for them. Several studies since 2010 have focused on pain in NH residents with dementia, but there is a lack of systematic reviews on the prevalence of pain in NH residents with dementia.

AIM

To systematically review observational studies published from 2010 to 2023 on how pain is assessed and prevalence of pain found in NH residents with dementia.

METHODS

A systematic search was conducted in the MEDLINE, PubMed, PsycINFO, Embase, CINAHL, AgeLine, and Cochrane databases for studies published from January 2010 to August 2023. Studies were included if they were observational studies with a quantitative design where self-report, staff assessment, and/or chart review were used to define the prevalence of pain in samples or subsamples of NH residents with dementia.

RESULTS

Of 184 studies considered, 25 were included. The studies assessed pain as daily, present, clinically relevant, chronic, intermittent, persistent pain and/or if pain affected quality of life. The prevalence of pain was high in most studies of NH residents with dementia independent of whether pain was reported as presence of pain or clinically relevant pain, but the prevalence varied from 8.6% to 79.6%. This prevalence was quite stable across the NH stay, but higher towards the end of life (up to 80.4%). Study designs and methodologies differed considerably. About half relied on an observational assessment inventory.

CONCLUSION

The number of studies focusing on pain in NH residents with dementia was restricted and methodologies differed considerably. Relatively few studies used an observational assessment inventory. In view of the fact that residents with dementia may have difficulties communicating pain, clinicians should pay attention to pain in these residents, systematically and reliably uncover pain by use of observational inventories, and subsequently treat pain to secure high quality care.

Nursing-sensitive quality indicators for quality improvement in Norwegian nursing homes - a modified Delphi study

BACKGROUND

Use of nursing-sensitive quality indicators (QIs) is one way to monitor the quality of care in nursing homes (NHs). The aim of this study was to develop a consensus list of nursing-sensitive QIs for Norwegian NHs.

METHODS

A narrative literature review followed by a non-in-person, two-round, six-step modified Delphi survey was conducted. A five-member project group was established to draw up a list of nursing-sensitive QIs from a preliminary list of 24 QIs selected from Minimum Data Set (2.0) (MDS) and the international Resident Assessment Instrument for Long-Term Care Facilities (interRAI LTCF). We included scientific experts (researchers), clinical experts (healthcare professionals in NHs), and experts of experience (next-of-kin of NH residents). The experts rated nursing-sensitive QIs in two rounds on a seven-point Likert scale. Consensus was based on median value and level of dispersion. Analyses were conducted for four groups: 1) all experts, 2) scientific experts, 3) clinical experts, and 4) experts of experience.

RESULTS

The project group drew up a list of 20 nursing-sensitive QIs. Nineteen QIs were selected from MDS/interRAI LTCF and one ('systematic medication review') from the Norwegian quality assessment system IPLOS ('Statistics linked to individual needs of care'). In the first and second Delphi round, 44 experts (13 researchers, 17 healthcare professionals, 14 next-of-kin) and 28 experts (8 researchers, 10 healthcare professionals, 10 next-of-kin) participated, respectively. The final consensus list consisted of 16 nursing-sensitive QIs, which were ranked in this order by the 'all expert group': 1) systematic medication review, 2) pressure ulcers, 3) behavioral symptoms, 4) pain, 5) dehydration, 6) oral/dental health problems, 7) urinary tract infection, 8) fecal impaction, 9) depression, 10) use of aids that inhibit freedom of movement, 11) participation in activities of interest, 12) participation in social activities, 13) decline in activities of daily living, 14) weight loss, 15) falls, and 16) hearing loss without the use of hearing aids.

CONCLUSIONS

Multidisciplinary experts were able to reach consensus on 16 nursing-sensitive QIs. The results from this study can be used to implement QIs in Norwegian NHs, which can improve the quality of care.

Pain and quality of life in nursing home residents with dementia after admission - a longitudinal study

BACKGROUND

Pain in nursing home (NH) residents with dementia is commonly reported and may affect Quality of Life (QoL) negatively. Few longitudinal studies have explored how pain and QoL develop in NH residents with dementia starting from their admission to the NH.

AIM

The aim was to explore pain, QoL, and the association between pain and QoL over time in persons with dementia admitted to a NH.

METHODS

A convenience sample, drawn from 68 non-profit NHs, included a total of 996 Norwegian NH residents with dementia (mean age 84.5 years, SD 7.6, 36.1% men) at NH admission (A1), with annual follow-ups for two years (A2 and A3). Pain and QoL were assessed using the Mobilization-Observation-Behavior-Intensity-Dementia-2 (MOBID-2) Pain Scale and the Quality of Life in Late-Stage Dementia (QUALID) scale, respectively, at all assessments. Severity of dementia, personal level of activities of daily living, general medical health, neuropsychiatric symptoms, and the prescription of psychotropic drugs and analgesics (opioids and/or paracetamol) were also assessed at all assessments.

RESULTS

Mean (SD) MOBID-2 pain intensity scores were 2.1 (2.1), 2.2 (2.2), and 2.4 (2.1) at A1, A2, and A3, respectively. Participants who were prescribed analgesics had higher pain intensity scores at all assessments than participants not prescribed analgesics. The mean (SD) QUALID scores at each assessment were 19.8 (7.1), 20.8 (7.2), and 22.1 (7.5) at A1, A2, and A3, respectively. In the adjusted linear mixed model, higher pain intensity score, prescription of opioids, and prescription of paracetamol were associated with poorer QoL (higher QUALID total score and higher scores in the QoL dimensions of sadness and tension) when assessed simultaneously. No time trend in QoL was found in these adjusted analyses.

CONCLUSION

NH residents with dementia who have higher pain intensity scores or are prescribed analgesics are more likely to have poorer QoL. Clinicians, NH administrators, and national healthcare authorities need to look into strategies and actions for pharmacological and non-pharmacological pain treatment to reduce pain intensity while simultaneously avoiding negative side effects of pain treatment that hamper QoL.

Prevalence and persistent prescription of analgesic drugs in persons admitted with dementia to a nursing home - A longitudinal study

The overall aim was to explore the prevalence and persistent regular prescription of opioids and paracetamol among nursing home (NH) residents with dementia at admission and over time. A total of 996 residents with dementia, mean (SD) age 84.5 (7.6) years and (36.1% men), were included at admission (A1). Yearly assessments were performed for two years (A2 and A3) or until death. Pain was assessed using the Mobilization-Observation-Behavior-Intensity-Dementia-2 (MOBID-2) Pain Scale. Information regarding prescription of analgesics, general physical health, personal activities of daily living, severity of dementia, neuropsychiatric symptoms, and prescription of psychotropic drugs was collected. A generalized linear mixed model was used to explore whether pain severity was associated with persistent and persistent prescription of opioids and/or paracetamol across timepoints. At A1, 495 of 996 (49.7%) NH residents were prescribed analgesics and prevalence increased at the follow-ups (A2: n = 630, 65.1%; A3: n = 382, 71.2%). Paracetamol was the most frequently prescribed analgesic at all assessments (A1: 45.5%; A2: 59.5%; A3: 67.1%). Opioid prescriptions were quite prevalent (A1: 18.1%; A2: 25.1%; A3: 28.3%), with odds approximately 13 times (OR = 13.3, 95% CI 6.8-26.0) and 9 times (OR = 8.6, 95% CI 3.7-20.3) higher for prescription at follow-up A2 and A3, respectively, relative to prescription at A1. In adjusted analyses, higher pain intensity and poor physical health were associated with prescription and persistent prescription of opioids and paracetamol. In conclusion, prevalence and persistent prescription of analgesics were high in NH residents with dementia. The odds for the prescription of opioids at follow-up were high if prescribed at baseline. Interdisciplinary collaboration, routine assessment of pain at admission and regularly thereafter, and systematic drug reviews are essential to adequately assess and treat pain in NH residents with dementia.

Pain in nursing home residents with dementia and its association to quality of life

OBJECTIVES

We aimed to describe pain, use of analgesics and quality of life (QoL) in people with dementia admitted to a Norwegian nursing home (NH), and to explore if and how pain was associated with their QoL when adjusting for sociodemographic characteristics, other health conditions and use of analgesics.

METHOD

A total of 953 Norwegian NH residents with dementia (mean age 84.0, SD 7.5 years, 35.8% men) were included at admission to the NH. Pain and QoL were assessed using the Mobilization-Observation-Behavior-Intensity-Dementia-2 (MOBID-2) Pain Scale and the Quality of Life in Late-Stage Dementia (QUALID) scale, respectively. Severity of dementia, personal level of activities of daily living, general medical health, neuropsychiatric symptoms, and the use of psychotropic drugs and analgesics were assessed.

RESULTS

In total, 36% of the participants had clinically relevant pain intensity (MOBID-2 ≥ 3) and 52% received analgesics. Paracetamol was most frequently prescribed (45%). In an adjusted linear mixed model, more severe pain was associated with higher QUALID total scores, indicating poorer QoL (regression coefficient 0.52, 95% CI 0.36-0.69).

CONCLUSION

Pain prevalence at NH admission was high in residents with dementia; half used analgesics, particularly paracetamol. More severe pain was associated with poorer QoL when adjusting for sociodemographic characteristics, other health conditions, and use of analgesics. The routine assessment of pain at NH admission can uncover undiagnosed and untreated pain and allow for adequate non-pharmacological and pharmacological pain management and likely increased QoL.

Opioid administration trends among long-stay community living centers residents with dementia

BACKGROUND

Pain assessment and management of Veterans with Alzheimer's disease and Related Dementia (ADRD) living in Community Living Centers (CLCs) is challenging. Safe and effective use of opioids in the treatment of pain is of great concern to patients and providers promulgating national policies and guidelines.

METHODS

This study examined long-stay CLC Veterans with ADRD identified in three regulatory periods (period 1: 10/2012-6/2013, n = 3347; period 2: 1/2014-11/2015, n = 4426; period 3: 1/2017-9/2018, n = 4444; Total N = 12,217).This population-based observational study used CLC Minimum Data Set (MDS) data in Fiscal Years (FYs) 2013-2018 and VA bar-code medication administration (BCMA) data. Opioid administration measures included: any opioids, long-term opioids, high-dose opioids, and co-administration with benzodiazepine. Measures were modeled using negative binomial regression with length of stay in CLC as offset adjusting for Veteran predisposing, enabling and need measures from the MDS.

RESULTS

Compared to period 1, any opioid administration was 26% lower in period 2, and 34% lower in period 3. Among Veterans who received any opioid medications over the three regulatory periods, high-dose and long-term opioid administration were more than 40% lower in periods 2 and 3 compared to period 1. Co-administration of opioid with benzodiazepine versus no opioid was 11% lower in period 2 and 34% lower in period 3 after adjusting for patient level covariates.

CONCLUSIONS

All patterns of opioid administration decreased over the four opioid regulations periods when guidelines were promulgated across the VA health system. Further research should clarify whether decreasing opioids among patients with ADRD impacted health outcomes.

Understanding Pain and Agitation Through System Analysis Algorithms in People With Dementia. A Novel Explorative Approach by the DIGI.PAIN Study

Background

Many people with dementia (PwD) live and die with undiagnosed and untreated pain and are no longer able to report their suffering. Several pain assessment tools have been developed, tested, and implemented in clinical practice, but nursing home patients are reported to be still in pain. Clinicians and research groups worldwide are seeking novel approaches to encode the prediction, prevalence, and associations to pain in PwD.

Participants

The data in this analysis are acquired from the COSMOS study, a cluster-randomized controlled trial (2014 to 2015), aimed to improve the quality of life in nursing home patients (N = 723) through the implementation of a multicomponent intervention. We utilize baseline data of PwD (N = 219) with complete datasets of pain and agitation.

Method

Systems analysis explores the relationship between pain and agitation using the Mobilization-Observation-Behavior-Intensity-Dementia (MOBID-2) Pain Scale, Cohen-Mansfield Agitation Inventory (CMAI), and Neuropsychiatric Inventory-Nursing Home version (NPI-NH). For each patient, the individualized continuous time trajectory, and rates of change of pain and agitation are estimated. We determine the relationship between these rates by analyzing them across the entire group.

Results

We found that the new analysis method can generate individualized estimations for pain and agitation evolution for PwD, as well as their relationship. For 189 of 219 PwD, results show that whenever pain increases or decreases, agitation does too, with the same rate. The method also identifies PwD for whom pain or agitation remains constant while the other varies over time, and patients for whom agitation and pain do not change together. The algorithm is scalable to other variables and compatible with wearable devices and digital sensors.

Conclusion

We presented a new approach to clinical data analysis using systems concepts and algorithms. We found that it is possible to quantify and visualize relationships between variables with a precision only dependent on the precision of measurements. This method should be further validated, but incipient results show great potential, especially for wearable-generated continuous data.

Factors associated with daily opioid use among aged home care clients: a cross-sectional analysis of Resident Assessment Instrument data

Aim

To examine which client characteristics and other factors, including possible adverse effects, identified in the Resident Assessment Instrument-Home Care (RAI-HC) are associated with daily opioid use among aged home care clients.

Findings

After adjustment for pain-related diseases, disabilities, depressive symptoms and the estimated severity of pain, daily opioid use was associated with osteoporosis, cancer within previous 5 years and greater disabilities in Instrumental Activities of Daily Living, and cognitive impairment was associated with less frequent opioid use. Constipation was the only adverse effect identified in the RAI-HC associated with daily opioid use.

Message

The pain of home care clients with cognitive impairment may not be treated optimally, whereas there might be prolonged opioid use without a sufficient evaluation of current pain among clients with osteoporosis, cancer within previous 5 years and disabilities in Instrumental Activities of Daily Living.

Purpose

To examine which client characteristics and other factors, including possible adverse effects, identified in the Resident Assessment Instrument—Home Care (RAI-HC) are associated with daily opioid use among aged home care clients.

Methods

The study sample comprised 2584 home care clients aged ≥ 65 years, of which 282 persons used opioids daily. Clients using opioids less than once daily were excluded. The cross-sectional data were gathered from each client’s first assessment with the RAI-HC during 2014. Multivariable logistic regression was used to study associations of daily opioid use with the clients’ characteristics and symptoms.

Results

Cognitive impairment was associated with less frequent opioid use after adjusting for pain-related diseases, disabilities and depressive symptoms (OR 0.43, 95% CI 0.32–0.58). The association was not explained by the estimated severity of pain. Osteoporosis, cancer within previous 5 years and greater disabilities in Instrumental Activities of Daily Living (IADL) were associated with daily opioid use regardless of the estimated severity of pain. Depressive symptoms and Parkinson’s disease were associated with daily opioid use only among clients with cognitive impairment, and disabilities in Activities of Daily Living, cancer, arthritis, fractures and pressure ulcers only among clients without cognitive impairment. Constipation was the only adverse effect associated with daily opioid use.

Conclusion

The pain of home care clients with cognitive impairment may not be treated optimally, whereas there might be prolonged opioid use without a sufficient evaluation of current pain among clients with osteoporosis, cancer within previous 5 years and disabilities in IADLs.

Pain in Dementia: Prevalence and Association With Neuropsychiatric Behaviors

CONTEXT

Pain is linked to behaviors and psychological symptoms of dementia (BPSD); however, it often remains underrecognized in this population.

OBJECTIVES

We aimed to investigate the prevalence and intensity of pain in people living in aged care homes with BPSD and by dementia subtypes and the association between pain intensity and BPSD.

METHODS

A 1-year retrospective cross-sectional analysis was conducted on BPSD and the presence of pain in referrals to a national BPSD support service using the Neuropsychiatric Inventory and PainChek®, respectively. Referrals were categorized into two groups: pain group and no pain group.

RESULTS

Of the 479 referrals (81.9 ± 8.3 years old) included in the analysis, two-thirds (65.6%) had pain identified, with almost half (48.4%) of these categorized as experiencing moderate-severe pain. Pain was highly prevalent (range: 54.6-78.6%) in all subtypes of dementia, particularly in mixed dementia and dementia with Lewy bodies. Compared with the no pain group, the pain group had 25.3% more neuropsychiatric behaviors, 33.6% higher total severity of these behaviors, and 31.4% higher total distress caused to caregivers. For all results, effect sizes were small to medium (η²p = 0.04-0.06). Despite a high prevalence of aggressive or agitated behaviors across the entire group, the pain group was 3.8 times more likely to experience these behaviors than referrals not in pain.

CONCLUSION

There is a strong need to consider the possibility of pain as a contributor to behavioral changes in aged care residents living with dementia.

Pain, Complex Chronic Conditions and Potential Inappropriate Medication in People with Dementia. Lessons Learnt for Pain Treatment Plans Utilizing Data from the Veteran Health Administration

Alzheimer's disease and related dementias (ADRD), pain and chronic complex conditions (CCC) often co-occur leading to polypharmacy and with potential inappropriate medications (PIMs) use, are important risk factors for adverse drug reactions and hospitalizations in older adults. Many US veterans are at high risk for persistent pain due to age, injury or medical illness. Concerns about inadequate treatment of pain-accompanied by evidence about the analgesic efficacy of opioids-has led to an increase in the use of opioid medications to treat chronic pain in the Veterans Health Administration (VHA) and other healthcare systems. This study aims to investigate the relationship between receipt of pain medications and centrally (CNS) acting PIMs among veterans diagnosed with dementia, pain intensity, and CCC 90-days prior to hospitalization. The final analytic sample included 96,224 (81.7%) eligible older veterans from outpatient visits between October 2012-30 September 2013. We hypothesized that veterans with ADRD, and severe pain intensity may receive inappropriate pain management and CNS-acting PIMs. Seventy percent of the veterans, and especially people with ADRD, reported severe pain intensity. One in three veterans with ADRD and severe pain intensity have an increased likelihood for CNS-acting PIMs, and/or opioids. Regular assessment and re-assessment of pain among older persons with CCC, patient-centered tapering or discontinuation of opioids, alternatives to CNS-acting PIMs, and use of non-pharmacological approaches should be considered.

Pain prevalence among residents living in nursing homes and its association with quality of life and well-being

BACKGROUND

Pain is common and often more complex to assess among nursing homes residents with cognitive impairments. Thus, more research is needed of different pain assessment methods in elderly care and how these assessments outcomes are related to quality of life, as there mostly should be a negative relationship. There is a risk that pain are under diagnosed among persons with cognitive impairment.

AIM

The aim was to describe and compare pain prevalence among nursing home residents (1) using different pain assessment methods (2) in relation to cognitive status and to (3) examine associations between pain and quality of life or well-being.

METHODS

A cross-sectional correlational design was used, participants were 213 nursing home residents and data were collected through interviews using standardised protocols. Instrument used were Katz index of ADL, Mini-Mental-State-Examination, Quality of Life in Late-Stage Dementia scale, WHO-5 well-being index, Numeric Rating Scale and Doloplus-2 scale.

RESULTS

The results showed high pain prevalence, but no significant difference based on cognitive level. Pain classification at the individual level varied somewhat when different instruments are used. The results indicated that use of a single-item proxy-measure for pain tends to show higher pain prevalence and was not statistically significant related to quality of life. The relationship with quality of life was statistically significant when self-rated pain instruments or multi-component observation were used.

CONCLUSIONS

The study shows that it is difficult to estimate pain in residents living at nursing homes and that it continues to be a challenge to solve. Self-rated pain should be used primarily to assess pain, and a multi-component observation scale for pain should be used when residents are cognitively impaired. Both self-rated pain and multi-component observation also support the well-known link between pain and quality of life. Single-item proxy assessments should only be used in exceptional cases.

Automated vs. manual pain coding and heart rate estimations based on videos of older adults with and without dementia

Introduction

Technological advances have allowed for the estimation of physiological indicators from video data. FaceReader™ is an automated facial analysis software that has been used widely in studies of facial expressions of emotion and was recently updated to allow for the estimation of heart rate (HR) using remote photoplethysmography (rPPG). We investigated FaceReader™-based heart rate and pain expression estimations in older adults in relation to manual coding by experts.

Methods

Using a video dataset of older adult patients with and without dementia, we assessed the relationship between FaceReader’s™ HR estimations against a well-established Video Magnification (VM) algorithm during baseline and pain conditions. Furthermore, we examined the correspondence between the Facial Action Coding System (FACS)-based pain scores obtained through FaceReader™ and manual coding.

Results

FaceReader’s™ HR estimations were correlated with VM algorithm in baseline and pain conditions. Non-verbal FaceReader™ pain scores and manual coding were also highly correlated despite discrepancies between the FaceReader™ and manual coding in the absolute value of scores based on pain-related facial action coding of the events preceding and following the pain response.

Conclusions

Compared to expert manual FACS coding and optimized VM algorithm, FaceReader™ showed good results in estimating HR values and non-verbal pain scores.

Differences in Staff-Assessed Pain Behaviors among Newly Admitted Nursing Home Residents by Level of Cognitive Impairment

OBJECTIVE

Pain is common among nursing home residents with cognitive impairment and dementia. Pain is often underdiagnosed and undertreated, which may lead to adverse health outcomes. Nonverbal behaviors are valid indicators of pain, but the extent to which these behavioral expressions vary across levels of cognitive impairment is unknown. This study sought to examine differences in the prevalence of pain behaviors among nursing home residents with varying levels of cognitive impairment.

METHODS

The Minimum Data Set, version 3.0, was used to identify newly admitted nursing home residents with staff-assessed pain (2010-2016, n = 1,036,806). Staff-assessed pain behaviors included nonverbal sounds, vocal complaints, facial expressions, and protective body movements or postures over a 5-day look-back period for residents unable or unwilling to self-report pain. The Cognitive Function Scale was used to categorize residents as having no/mild, moderate, or severe cognitive impairment. Modified Poisson models provided adjusted prevalence ratios (aPR) and 95% CIs.

RESULTS

Compared to residents with no/mild cognitive impairments (any pain: 48.1%), residents with moderate cognitive impairment (any pain: 42.4%; aPR: 0.94 [95% CI 0.93-0.95]) and severe cognitive impairment (any pain: 38.4%; aPR: 0.86 [95% CI 0.85-0.88]) were less likely to have any pain behavior documented. Vocal pain behaviors were common (43.5% in residents with no/mild cognitive impairment), but less so in those with severe cognitive impairment (20.1%). Documentation of facial expressions and nonverbal pain behaviors was more frequent for residents with moderate and severe cognitive impairment than those with no/mild cognitive impairment.

CONCLUSIONS

The prevalence of behaviors indicative of pain differs by level of cognitive impairment. Pain evaluation and management plays an important role in treatment and care outcomes. Future work should examine how practitioners' perceptions of pain behaviors influence their ratings of pain intensity and treatment choices.

Prescription analgesia and adjuvant use by pain severity at admission among nursing home residents with non-malignant pain

OBJECTIVE

We estimated the use of prescribed analgesics and adjuvants among nursing home residents without cancer who reported pain at their admission assessment, in relation to resident-reported pain severity.

METHODS

Medicare Part D claims were used to define 3 classes of analgesics and 7 classes of potential adjuvants on the 21st day after nursing home admission (or the day of discharge for residents discharged before that date) among 180,780 residents with complete information admitted between January 1, 2011 and December 9, 2016, with no cancer diagnosis.

RESULTS

Of these residents, 27.9% reported mild pain, 46.6% moderate pain, and 25.6% reported severe pain. The prevalence of residents in pain without Part D claims for prescribed analgesic and/or adjuvant medications was 47.3% among those reporting mild pain, 35.7% among those with moderate pain, and 24.8% among those in severe pain. Among residents reporting severe pain, 33% of those ≥ 85 years of age and 35% of those moderately cognitively impaired received no prescription analgesics/adjuvants. Use of all classes of prescribed analgesics and adjuvants increased with resident-reported pain severity, and the concomitant use of medications from multiple classes was common.

CONCLUSION

Among nursing home residents with recognized pain, opportunities to improve the pharmacologic management of pain, especially among older residents, and those living with cognitive impairments exist.

LIVE@Home.Path-innovating the clinical pathway for home-dwelling people with dementia and their caregivers: study protocol for a mixed-method, stepped-wedge, randomized controlled trial

BACKGROUND

The global health challenge of dementia is exceptional in size, cost and impact. It is the only top ten cause of death that cannot be prevented, cured or substantially slowed, leaving disease management, caregiver support and service innovation as the main targets for reduction of disease burden. Institutionalization of persons with dementia is common in western countries, despite patients preferring to live longer at home, supported by caregivers. Such complex health challenges warrant multicomponent interventions thoroughly implemented in daily clinical practice. This article describes the rationale, development, feasibility testing and implementation process of the LIVE@Home.Path trial.

METHODS

The LIVE@Home.Path trial is a 2-year, multicenter, mixed-method, stepped-wedge randomized controlled trial, aiming to include 315 dyads of home-dwelling people with dementia and their caregivers, recruited from 3 municipalities in Norway. The stepped-wedge randomization implies that all dyads receive the intervention, but the timing is determined by randomization. The control group constitutes the dyads waiting for the intervention. The multicomponent intervention was developed in collaboration with user-representatives, researchers and stakeholders to meet the requirements from the national Dementia Plan 2020. During the 6-month intervention period, the participants will be allocated to a municipal coordinator, the core feature of the intervention, responsible for regular contact with the dyads to facilitate L: Learning, I: Innovation, V: Volunteering and E: Empowerment (LIVE). The primary outcome is resource utilization. This is measured by the Resource Utilization in Dementia (RUD) instrument and the Relative Stress Scale (RSS), reflecting that resource utilization is more than the actual time required for caring but also how burdensome the task is experienced by the caregiver.

DISCUSSION

We expect the implementation of LIVE to lead to a pathway for dementia treatment and care which is cost-effective, compared to treatment as usual, and will support high-quality independent living, at home.

Psychometric Evaluation of a Pain Intensity Measure for Persons with Dementia

OBJECTIVE

The goal of this study was to conduct initial psychometric analyses of a seven-item pain intensity measure for persons with dementia (PIMD) that was developed using items from existing pain observational measures.

DESIGN AND METHODS

We evaluated validity by examining associations with an expert clinician's pain intensity rating (ECPIR) and an established pain observation tool (Mobilization Observation Behaviour Intensity Dementia [MOBID]). We also examined correlations between the PIMD and known correlates of pain: depression, sleep disturbances, agitation, painful diagnoses, and caregiver pain reports. We examined the differences between PIMD scores for "at rest" and "during movement" observations. We assessed reliability by calculating Cronbach's alpha and estimating inter-rater reliability using intraclass correlations (ICCs). Finally, we examined whether six additional "recent changes in behavior" items improved the PIMD's ability to predict expert clinicians' pain ratings.

SETTING

Sixteen nursing homes located in Alabama, Georgia, Pennsylvania, and New Jersey.

PARTICIPANTS

One hundred ninety residents with moderate to severe cognitive impairment, mean age of 84 years, 49.5% female, and 70% white.

RESULTS

PIMD during movement scores were highly correlated with the ECPIR and overall MOBID scores. As expected, there were large differences between at rest and during movement PIMD scores. Associations of PIMD with known correlates of pain were generally low and statistically nonsignificant. Internal consistency was supported with a Cronbach alpha of 0.72 and an inter-rater ICC of 0.82 for during movement PIMD scores.

CONCLUSIONS

Initial evaluation of the PIMD supports its validity and reliability. Additional testing is needed to evaluate the tool's sensitivity to changes in pain intensity.

Opioid Use After Hospital Care due to Hip Fracture Among Community-Dwelling Persons With and Without Alzheimer's Disease

BACKGROUND

Hip fractures are common among persons with Alzheimer's disease (AD), but problems in pain assessment may lead to insufficient analgesia after hospitalization.

OBJECTIVE

We investigated the prevalence of opioid use in the 6 months after discharge from hospital care due to hip fracture among community-dwellers with and without AD.

SETTING AND METHOD

The Medication use and Alzheimer's disease (MEDALZ) cohort was used for this study, consisting of all community-dwelling persons newly diagnosed with AD during 2005-2011 in Finland and their comparison persons without AD matched on age, sex, and region of residence at the time of AD diagnosis. Data were collected from nationwide healthcare registers.

MAIN OUTCOME MEASURES

We investigated opioid use versus non-use in persons with and without AD in the 6 months after discharge from hospital care due to hip fracture.

RESULTS

Altogether 2342 persons with AD and 1615 persons without AD, discharged to community settings within ≤ 120 days after a hip fracture, were included. A higher percentage of persons with AD used opioids compared to those without AD, 39.5% [95% confidence interval (CI) 37.5-41.5] versus 31.2% (95% CI 28.9-33.5). Persons with AD used more frequently strong opioids during the first 3 months and buprenorphine during the 6-month period, and used weak opioids less frequently after the first month after discharge compared to those without AD.

CONCLUSIONS

Frequent opioid use after hospital care due to hip fracture may indicate increased attention to pain among persons with AD. Nevertheless, the benefits and harms of opioid use should be evaluated regularly in community-dwelling older persons.

Effects of age and cognitive function on data quality of standardized surveys in nursing home populations

Background

Data quality is of special concern when it comes to survey research in nursing homes. Very little is known about specifics of cognitively impaired elderly in responding to survey questions. This study examines effects of cognitive impairment, age, gender, and interview duration on the data quality in a sample of 659 nursing home residents (NHR).

Methods

Within a cross-sectional design, survey methodology was used to evaluate the pain situation in 13 nursing homes. Residents were stratified into NHR with no/mild (Mini-Mental State Examination MMSE: 18–30) and NHR with moderate (MMSE: 10–17) cognitive impairment. Data quality is measured by item nonresponse (INR). Correlation analyses, ANCOVA, linear and logistic regression models are applied.

Results

Neither interview duration nor gender have effects on item nonresponse. Age accounts for higher INR (β = 0.12, p < 0.001). Cognitive impairment strongly predicts INR (β = − 0.40, p < 0.001). INR significantly differs between NHR with no/mild (3.98%) and moderate cognitive impairment (11.85%). The likelihood of INR > 5% for residents with moderate cognitive impairment is 3.8-times (p < 0.001) of that for those with no/mild impairment.

Conclusions

Surveys are adequate for residents with no/mild cognitive impairment but data quality is threatened in residents with moderate impairments. Precision and validity of responses from NHR with progressed cognitive impairment are potentially limited and results may be biased. The results clearly do support the need for a multidisciplinary ‘general theory’ of the question−/answer-process which has to be also inclusive for cognitively impaired elderly persons.

Before Hospice: Symptom Burden, Dementia, and Social Participation in the Last Year of Life

Background: Little is known about clinical symptom burden, dementia, and social isolation in the last year of life among older adults. Objective: To describe and contrast the type and severity of symptom burden for older decedents with and without dementia, and whether specific symptoms and presence of dementia are associated with limitations in social participation in the last year of life. Design: Cross-sectional logistic regression analysis of a population-based study. Setting/Subjects: A total of 1270 community-dwelling adults of age ≥65 years in the United States participated in the 2011 National Health and Aging Trends Study and died by 2015. Measurements: Dementia status, 13 clinical symptoms, and limitations in 6 social activities were drawn from the interview preceding death. Severity of sensory, physical, and psychiatric symptom burden was examined in tertiles. Results: Decedents with dementia (37.3%) had higher prevalence of all symptoms (p's < 0.05), except insomnia and breathing problems. Dementia was associated with greater likelihood of high versus low burden of sensory (odds ratio [OR] 4.52 [95% confidence interval {CI} 3.08-6.63]), physical (OR 3.49 [95% CI 2.48-4.91]), and psychiatric (OR 2.80 [95% CI 1.98-3.95]) symptoms. Dementia and physical symptoms (problems with speaking, leg strength/movement, and balance) were independently associated with limitations in at least three social activities (p's < 0.05 for adjusted ORs). Conclusion: Symptom burden is higher in patients with dementia. Dementia and physical symptoms are associated with social activity limitations. Older patients with dementia or physical symptoms may benefit from earlier emphasis on palliative care and quality of life.

Psychosis symptoms in nursing home residents with and without dementia-Cross-sectional analyses from the COSMOS study

OBJECTIVE

To investigate the characteristics of nursing home residents with psychosis and the association with potential underlying factors, such as pain, sleep disturbances, and antipsychotic medication.

METHOD

Five hundred forty-five residents with and without dementia from 67 Norwegian nursing home units were included in the cross-sectional analyses. Psychosis was the main outcome measure in our study; other outcome measures include quality of life (QoL), activities of daily living (ADL) function, cognitive function, pain, and antipsychotic medication.

RESULTS

One hundred twelve residents had one or more symptoms of psychosis, and compared with residents without psychosis, they had lower QoL (p < 0.001), ADL function (p = 0.003), and cognitive functioning (p = 0.001). Adjusted logistic regression analyses showed that psychosis was associated with the prevalence of pain (OR: 3.19; 95% CI, 1.94-5.24), sleep disturbances (OR: 4.51; 95% CI, 2.91-6.99), and total number of medication (OR: 1.10; 95% CI, 1.03-1.17). Residents with psychosis but without antipsychotic medication had better QoL (p = 0.005) compared with residents receiving any antipsychotics.

CONCLUSION

Psychosis in NH residents is associated with pain, sleep disturbances, and number of medications. Residents with psychosis have poor QoL, although better QoL was observed among those who did not use antipsychotic medication.

Do Nursing Home Residents With Dementia Receive Pain Interventions?

This study compares pain interventions received by nursing home residents with and without dementia. Secondary data analyses of cross-sectional data from 50,673 nursing home residents in New York State were collected by the Minimum Data Set 3.0. Frequency distributions and bivariate analyses with χ2 tests were used to organize and summarize the data. Logistic regression analyses were performed to quantify the relationship between dementia and pain interventions. Our results show that residents with dementia had significantly fewer pain assessments and less reported pain presence than their counterparts. After adjusting for covariates, the results indicate that residents with dementia were significantly less likely to receive pro re nata and nonmedication pain intervention. However, there were no significant differences in scheduled pain medication between the 2 groups. To address the gap, we need more research to design a pain assessment tool that can differentiate severity of pain so that appropriate interventions can be applied.

Quality of Life and Pain Medication Use in Persons With Advanced Dementia Living in Long-Term Care Facilities

OBJECTIVES

In residents with dementia living in a long-term care facility (LTCF), un(der)treated pain may trigger behavioral disturbances, mood syndromes, and deterioration of physical functioning and self-maintenance. Because these factors can have considerable impact on the quality of life (QoL), this study aimed to (1) compare characteristics of persons with advanced dementia living in LTCFs with and without pain medication; (2) compare QoL in these persons with and without pain, stratified by type of pain medication use; and (3) explore associations between the use of paracetamol and QoL in persons with advanced dementia living in LTCFs.

DESIGN AND SETTING

This study analyzed baseline data from the Communication, Systematic Assessment and Treatment of Pain, Medication Review, Occupational Therapy, and Safety Study; a multicenter, cluster-randomized effectiveness-implementation clinical hybrid trial in 67 Norwegian LTCF clusters.

PARTICIPANTS

In total, 407 LTCF residents (rural and urban areas) aged ≥65 years, with Functional Assessment Staging scores of 5-7 (ie, moderate to advanced dementia).

MAIN OUTCOME MEASURE

QoL as assessed by the 6 QUALIDEM (validated questionnaire to measure QoL in persons with dementia living in LTCF) domains applicable to persons with moderate to severe dementia. The association between QoL and paracetamol was estimated using linear mixed-effect models, adjusting for confounding variables.

RESULTS

62.0% used pain medication (paracetamol, opioids, or both). QoL was lower in residents using pain medication, compared with those without pain medication [mean QUALIDEM score 68.8 (standard deviation 17.4 vs) 75.5 (standard deviation 14.6), respectively, P < .001). Multilevel analysis showed that paracetamol use was not associated with QoL.

CONCLUSIONS AND IMPLICATIONS

Persons with advanced dementia living in LTCF using pain medication have a lower QoL compared with those not using pain medication. These results are of key importance for the clinician because they stress the need for regular medication review and pain management. When measured cross-sectionally, use of paracetamol is not associated with increased QoL.

Pain Expressions in Dementia: Validity of Observers' Pain Judgments as a Function of Angle of Observation

Facial expressions of pain are important in assessing individuals with dementia and severe communicative limitations. Though frontal views of the face are assumed to allow for the most valid and reliable observational assessments, the impact of viewing angle is unknown. We video-recorded older adults with and without dementia using cameras capturing different observational angles (e.g., front vs. profile view) both during a physiotherapy examination designed to identify painful areas and during a baseline period. Facial responses were coded using the fine-grained Facial Action Coding System, as well as a systematic clinical observation method. Coding was conducted separately for panoramic (incorporating left, right, and front views), and a profile view of the face. Untrained observers also judged the videos in a laboratory setting. Trained coder reliability was satisfactory for both the profile and panoramic view. Untrained observer judgments from a profile view were substantially more accurate compared to the front view and accounted for more variance in differentiating non-painful from painful situations. The findings add specificity to the communications models of pain (clarifying factors influencing observers' ability to decode pain messages). Perhaps more importantly, the findings have implications for the development of computer vision algorithms and vision technologies designed to monitor and interpret facial expressions in a pain context. That is, the performance of such automated systems is heavily influenced by how reliably these human annotations could be provided and, hence, evaluation of human observers' reliability, from multiple angles of observation, has implications for machine learning development efforts.

A retrospective review of pain management in Tasmanian residential aged care facilities

Background

The management of pain by GPs for residents of aged care facilities (ACFs) is very common.

Aim

To measure the prevalence and assess the management of pain in ACF residents, particularly those with dementia.

Design & setting

A retrospective review of ACF residents' medical records was undertaken at five southern Tasmanian (Australia) ACFs.

Method

Data extracted included results of the most recent assessment of pain and its management, frequency and treatment of pain incidents in the previous 7 days, demographics, and medical and medication history. Univariate analysis was used to identify variables associated with increased frequency of pain episodes.

Results

The final analysis included 477 residents. At least one episode of pain in the preceding 7 days was documented in 25.6% (n = 122) of residents' notes. Pain episodes were most commonly managed by analgesics (45.5%), massage (40.7%), and heatpacks (13.8%). Residents with dementia were not less likely to have pain identified during the past week (14% versus 20%; P = 0.09), but they were much less likely to have pain identified on their most recent pain assessment (P = 0.03).

Conclusion

GPs should carefully consider the suitability of using 'as required' analgesics. Furthermore, on admission to an ACF, GPs need to ensure a patient's medical history includes all pain or potentially pain-causing conditions, to ensure that a resident's pain assessment is complete. This is especially necessary for those with dementia, to ensure that staff remain vigilant about the possibility of the resident experiencing pain.

Pain, aging and dementia: Towards a biopsychosocial model

Dementia is a progressive disease associated with irreversible impairment and loss of cognitive abilities. About half of older people with dementia experience pain. In this paper, we propose that pain in older people with dementia can be conceptualized as the final result of the interaction of three heterogeneous phenomena, pain, aging, and dementia, which are created and influenced by the interactions of predisposing, lifelong, and current biopsychosocial factors. We review pain assessment in people with dementia using both self-report and observational/behavioral measures. We then review the biological/sensory, psychological (cognitive and affective) and social dimensions of pain in dementia. The available data suggest that dementia does not impact pain threshold or tolerance. To date, there is little research on the social dimension of pain in dementia. Changes in the affective domain in response to experimental pain have been contradictory with evidence supporting both increased and decreased unpleasantness and emotional responsiveness in people with dementia compared to healthy controls. Clinically, depression is a significant burden for older people with dementia and chronic pain. The relationship between pain and other neuropsychiatric symptoms is controversial, and there is insufficient evidence on which to base conclusions. Some of the most important dementia-related changes may arise in the cognitive domain, including impairments of semantic and episodic memory for pain, executive function, and pain anticipation. Changes in brain activation and interconnectivity support many of these conclusions. Despite methodological limitations, we conclude there are compelling preliminary data to support a biopsychosocial framework of pain and dementia. Future research directions, especially the need for improved assessment tools, are highlighted.

Opioid use and the presence of Alzheimer's disease and related dementias among elderly Medicare beneficiaries diagnosed with chronic pain conditions

Introduction

There is scant literature on the use of opioids among community-dwelling elderly with Alzheimer's disease and related dementias (ADRD).

Methods

We adopted a retrospective, cross-sectional study design using Medicare Current Beneficiary Survey data from 2006 to 2013. The study sample included elderly community-dwelling Medicare beneficiaries who were diagnosed with chronic pain conditions and had Medicare fee-for-service plans for the entire year. We conducted bivariate χ² test and multivariate logistic regression to examine the relationship between opioid use and ADRD status.

Results

The study sample included 19,347 Medicare beneficiaries; 7.7% of them had ADRD. We found no statistically significant difference in opioid use by ADRD status in the unadjusted analysis; however, controlling for various factors, those with ADRD had lower odds of opioid use (adjusted odds ratio = 0.81, 95% confidence interval = 0.71, 0.93) than those without ADRD.

Discussion

This population-based study suggests that elderly Medicare beneficiaries with ADRD and chronic pain conditions may have undertreatment of pain.

The knowledge and attitudes of general practitioners to the assessment and management of pain in people with dementia

BACKGROUND

Pain in people with dementia is underdiagnosed and undertreated. General practitioners (GPs) play a pivotal role in dementia care but their perspectives on pain in people with dementia remains under-researched. The aim of this study was to explore GPs' knowledge and attitudes towards pain assessment and management in people with dementia.

METHODS

This was a descriptive cross-sectional study. A questionnaire was adapted from a previous study and piloted with 5 GPs. The questionnaire was posted to a census sample of all GPs in Cork city and county in the southern region of Ireland. The questionnaire collected demographic information, responses to a series of Likert-type statements assessing GPs' knowledge and attitudes, and provided an opportunity for the GP to give qualitative feedback on their experiences of managing pain in dementia. SPSS v25 was used for statistical analysis. Qualitative responses were thematically analysed.

RESULTS

Of the 320 questionnaires posted, 157 completed questionnaires were returned (response rate of 49%). The sample was representative of GPs nationally in terms of years in GP practice and practice location. Over two-thirds (108/157) of respondents had a nursing home commitment. Only 10% of respondents (16/157) were aware of any dementia-specific pain assessment tools. The larger the nursing home commitment of the GP the more likely they were to be familiar with these tools (p = 0.048). The majority of respondents (113/157) believed people with dementia could not self-report pain. Respondents were uncertain about the safety of using opioid medications to treat pain in people with dementia with only 51.6% agreeing that they were safe. The qualitative comments highlighted the importance the GPs placed on surrogate reports of pain, GPs' uncertainty regarding the value of formal pain assessment tools and the challenges caused by under-resourcing in general practice.

CONCLUSION

This study has highlighted aspects of pain assessment and management in dementia that GPs find challenging. Guidance on pain assessment and management in people with dementia do not appear to be translating into clinical practice. The findings will inform educational interventions being developed by our research team as part of the implementation of the Irish national dementia strategy. The knowledge and attitudes of general practitioners to the assessment and management of pain in people with dementia.

Quebec physicians' perspectives on medical aid in dying for incompetent patients with dementia

OBJECTIVES

To elicit Quebec physicians' attitudes towards extending medical aid in dying (MAiD) to incompetent patients and to compare the attitudes of family physicians to those of other medical specialists.

METHODS

We conducted a postal survey among physicians caring for patients with dementia. We used hypothetical vignettes to elicit their attitudes towards MAiD and continuous deep sedation (CDS) to relieve suffering at end of life. Two patients were depicted in the vignettes: one with cancer eligible for MAiD and one with dementia. The generalized estimating equation approach was used to investigate factors associated with attitudes, including the stage of the illness (advanced vs terminal dementia) and the presence or absence of a prior written request.

RESULTS

A total of 136 physicians out of 653 returned the questionnaire. Physicians favoured CDS over MAiD for relieving suffering in the cancer vignette (93% vs 79%; p = 0.002). In advanced dementia, 45% of physicians supported giving the patient access to MAiD with a written request and 14% without such request. At the terminal stage of dementia, these proportions increased to 71% and 43%, respectively (p < 0.001), reaching 79% and 52% among family physicians. Support for CDS in terminal dementia was lower than in end-stage cancer (68% vs 93%; p < 0.001) and equal to MAiD with a written request (68% vs 71%; p = 0.623).

CONCLUSION

Many Quebec physicians support extending MAiD to incompetent patients with dementia to relieve suffering at the terminal stage. This finding will inform current deliberations as to whether MAiD should be extended to these patients.

Behavioral Problems and Dementia

Behavioral problems decrease quality of life of people with dementia and their care providers. Three main consequences of dementia are functional impairment and in some cases also mood disorders and psychosis. These consequences, alone or in combination, result in 3 main behavioral problems: apathy, agitation, and rejection of care/aggression. Nonpharmacologic management strategies include meaningful activities and individualized comfort care, for example, Namaste Care. If needed, pharmacologic management should concentrate on treatment of main dementia consequences, especially depression, instead of treating secondary symptoms, for example, insomnia. Use of antipsychotics should be minimized but antipsychotics may be necessary for augmentation of antidepressants.

A novel pain assessment tool incorporating automated facial analysis: interrater reliability in advanced dementia

OBJECTIVES

Regardless of its severity, dementia does not negate the experience of pain. Rather, dementia hinders self-reporting mechanisms in affected individuals because they lose the ability to do so. The primary aim of this study was to examine the interrater reliability of the electronic Pain Assessment Tool (ePAT) among raters when assessing pain in residents with moderate-to-severe dementia. Secondly, it sought to examine the relationship between total instrument scores and facial scores, as determined by automated facial expression analysis.

STUDY DESIGN

A 2-week observational study.

SETTING

An accredited, high-care, and dementia-specific residential aged care facility in Perth, Western Australia.

PARTICIPANTS

Subjects were 10 residents (age range: 63.1-84.4 years old) predominantly with severe dementia (Dementia Severity Rating Scale score: 46.3±8.4) rated for pain by 11 aged care staff. Raters (female: 82%; mean age: 44.1±12.6 years) consisted of one clinical nurse, four registered nurses, five enrolled nurses, and one care worker.

MEASUREMENTS

ePAT measured pain using automated detection of facial action codes and recordings of pain behaviors.

RESULTS

A total of 76 assessments (rest =38 [n=19 pairs], movement =38 [n=19 pairs]) were conducted. At rest, raters' agreement was excellent on overall total scores (coefficient of concordance =0.92 [95% CI: 0.85-0.96]) and broad category scores (κ=1.0). Agreement was moderate (κ=0.59) on categorical scores upon movement, while it was exact in 68.4% of the cases. Agreement in actual pain category scores gave κw=0.72 (95% CI: 0.58-0.86) at rest and κw=0.69 (95% CI: 0.50-0.87) with movement. All raters scored residents with higher total scores post-mobilization compared to rest. More facial action unit codes were also detected during pain (mean: 2.5 vs 1.9; p<0.0012) and following mobilization (mean: 2.5 vs 1.7; p<0.0001) compared to no pain and rest, respectively.

CONCLUSIONS

ePAT, which combines automated facial expression analysis and clinical behavioral indicators in a single observational pain assessment tool, demonstrates good reliability properties, which supports its appropriateness for use in residents with advanced dementia.

Providing care for a person with late-stage dementia at home: What are carers’ experiences?

Background

It is widely reported that carers who provide care for a family member with dementia endure physical and psychological burdens. Not only do they fulfil an important role for the person with dementia but also for the wider society. This study aims to explore the experiences of carers who provide end-of-life care for a person with late-stage dementia at home.

Method

Semi-structured interviews were conducted with 17 current carers and 6 past carers of a family member with late-stage dementia. Data was analysed using interpretative phenomenological analysis.

Results

Four super-ordinate themes were identified which described the challenges faced by carers at different stages of their care giving journey: (1) The experience of dementia grief; (2) Parenting the parent; (3) Seeking support; (4) Death, dying and life after death.

Conclusion

Dementia grief was experienced by carers as a result of a relationship change and an inability to recognise the person with dementia as their mother, father or spouse. A role transition ensued resulting in the carer adopting the role of parent. Carers expressed a desire to provide care for the person with dementia at home until the time of death; however, support is required in this area at both individual and community level. Family carers require education to help identify the dying phase which will assist to minimise the shock of death. Strong evidence suggests that the burden of care may leave family carers poorly equipped to adapt to life after the death of the person with dementia. Greater pre-death support is required to facilitate a better post bereavement adjustment.

Evaluation of the impact of telementoring using ECHO© technology on healthcare professionals' knowledge and self-efficacy in assessing and managing pain for people with advanced dementia nearing the end of life

Background

Pain assessment and management in advanced and end-stage dementia are challenging; patients are at risk of under-diagnosis, under-assessment and under-treatment. Previous research has highlighted the importance of needs-driven training and development in this area for physicians, nurses and healthcare assistants (HCAs) across specialties, disciplines and care settings. This study used teleconferencing technology to connect healthcare professionals across multiple settings and disciplines in real-time clinics, based on the Project ECHO© model. This paper reports the evaluation of the clinics by physicians, nurses and HCAs, including their knowledge and self-efficacy in pain assessment and management for patients with advanced and end-stage dementia.

Methods

A mixed method evaluation comprising quantitative survey of self-reported knowledge and self-efficacy pre- and post-ECHO clinic participation, and qualitative exploration of experiences of the clinics using focus group interviews. A census approach to sampling was undertaken. Pre- and post-ECHO evaluations were administered electronically using Survey Monkey software. Mann-Whitney U tests were used to explore differences in knowledge and self-efficacy scores pre- and post-ECHO clinic participation. Statistical significance was set a-priori at p = 0.05. Focus groups were video- and audio-recorded, transcribed verbatim and analysed using Braun & Clarke’s model of thematic analysis.

Results

Eighteen healthcare professionals [HCPs] (physicians [n = 7], nurses [n = 10], HCA [n = 1]) and twenty HCPs (physicians [n = 10], nurses [n = 10]) completed pre- and post-ECHO evaluations respectively, reporting improvements in knowledge and self-efficacy on participation in ECHO clinics and perceived utility of the clinics. Seven HCPs (physicians [n = 2], nurses [n = 5]) participated in two focus groups. Four themes emerged: knowledge and skills development and dissemination; protected time; areas for improvement; and the future of ECHO.

Conclusions

Telementoring clinics for HCP education and training in pain assessment and management in advanced and end-stage dementia demonstrate a positive impact on knowledge and self-efficacy of HCPs and highlight the value of a cross-specialty network of practice which spans across disciplines/HCP types, care settings and geographical areas. Further development of ECHO services in this and in other clinical areas, shows significant potential to support delivery of high-quality care to complex patient populations.

[Restricted mobility in nursing home residents : The role of pain and cognitive capacity]

BACKGROUND

Pain, restriction of mobility and cognitive impairment are often present in old age and intensify each other.

OBJECTIVES

Is there a relationship between mobility, pain, cognitive capacity, diagnoses and number of prescribed medication for residents of nursing homes?

METHODS

Subgroup analysis of the baseline data from an intervention study for optimization of the medication safety of 120 nursing home residents.

RESULTS

Pain was presumed in 77.8% of the residents. Persons with cognitive impairment were more frequently affected. The results of the observational and self-reported pain assessment in cognitively impaired patients did not agree for two-thirds of the cases. A correlation between prevalence of pain, pain intensity and mobility could only be shown for persons without cognitive impairment. Half of the persons were unable to walk; 80% of the residents with analgesics as a permanent medication were more restricted in their mobility.

CONCLUSIONS

Cognitive impairment is associated with pain and reduced mobility, whereby self-rated pain did not concur with the observational pain assessment for two-thirds of the residents with cognitive impairment. This illustrates the difficulty of observational pain assessment.

Algoplus® Scale in Older Patients with Dementia: A Reliable Real-World Pain Assessment Tool

Pain is still a neglected clinical issue in elderly people with dementia and/or communicative disorders, with an unacceptable higher rate of under diagnosis and under treatment. Cognitive deficit and emotional and psychological disturbances entangle pain symptoms, affecting patient self-report. So far, observational pain tools do not have fully adequate clinimetric properties and quality requirements for easy-to-use daily rating. Older patients with dementia represent a clinical challenge. The assessment of pain is important for improving clinical outcomes, such as functional status, frailty trajectories, comorbidity, and quality of life. The PAINAID scale appears to be the most accurate pain tool in people with dementia along with the Algoplus® scale, a recently developed tool to rapidly assess acute pain in hospitals settings. The present study aimed to assess the clinimetric properties of the Algoplus®, as compared to PAINAID, for detecting acute pain in a real-world cohort of hospitalized older patients with dementia.

A painful experience of limited understanding: healthcare professionals' experiences with palliative care of people with severe dementia in Norwegian nursing homes

BACKGROUND

People dying with dementia have significant healthcare needs, and palliative care, with its focus on comfort and quality of life, should be made available to these patients. The aim of this study was to explore and increase knowledge of healthcare professionals' experiences with palliative care to people with severe dementia in nursing homes.

METHODS

To describe the phenomenon under investigation, we used a phenomenological research approach grounded in the philosophy of Husserl. Data were collected using in-depth interviews with 20 healthcare professionals from four Norwegian nursing homes.

RESULTS

The general meaning structure of the healthcare professionals' experiences with providing palliative care to people with severe dementia is painfulness, due to their limited understanding of patients' individual modes of expression. The painfulness is illustrated by the following themes: challenges related to "reading" the patients' suffering, coming up short despite occasional success, handing the patients over to strangers, and disagreeing on the patients' best interests. The healthcare professionals struggled to understand patients by "reading" their suffering. Occasionally, they succeeded and were able to calm the patients, but they often had the feeling of coming up short in situations related to pain relief and coping with behavioural symptoms, such as aggression and rejection of care. They also found it painful when the weakest patients were moved from the sheltered unit to a somatic long-term unit and were handed over to strangers who did not know the patients' ways of expression. Although the healthcare professionals emphasized the importance of good collaboration with the patients' relatives to ensure the best possible palliative care, they frequently found themselves in difficult situations when they disagreed with the family on the patients' best interests.

CONCLUSIONS

We found healthcare professionals' experiences of providing palliative care to people with severe dementia to be painful. To be able to understand the patients better, long-term familiarity and knowledge of how to "read" and observe patients with severe dementia are necessary. Openness in cooperation with the patients' relatives and with the professional team may increase healthcare professionals' understanding of the patients' situations and hence improve the quality of care.

Pain in severe dementia: A comparison of a fine-grained assessment approach to an observational checklist designed for clinical settings

Background

Fine‐grained observational approaches to pain assessment (e.g. the Facial Action Coding System; FACS) are used to evaluate pain in individuals with and without dementia. These approaches are difficult to utilize in clinical settings as they require specialized training and equipment. Easy‐to‐use observational approaches (e.g. the Pain Assessment Checklist for Limited Ability to Communicate‐II; PACSLAC‐II) have been developed for clinical settings. Our goal was to compare a FACS‐based fine‐grained system to the PACSLAC‐II in differentiating painful from non‐painful states in older adults with and without dementia.

Method

We video‐recorded older long‐term care residents with dementia and older adult outpatients without dementia, during a quiet baseline condition and while they took part in a physiotherapy examination designed to identify painful areas. Videos were coded using pain‐related behaviours from the FACS and the PACSLAC‐II.

Results

Both tools differentiated between painful and non‐painful states, but the PACSLAC‐II accounted for more variance than the FACS‐based approach. Participants with dementia scored higher on the PACSLAC‐II than participants without dementia.

Conclusion

The results suggest that easy‐to‐use observational approaches for clinical settings are valid and that there may not be any clinically important advantages to using more resource‐intensive coding approaches based on FACS. We acknowledge, as a limitation of our study, that we used as baseline a quiet condition that did not involve significant patient movement. In contrast, our pain condition involved systematic patient movement. Future research should be aimed at replicating our results using a baseline condition that involves non‐painful movements.

Significance

Examining older adults with and without dementia, a brief observational clinical approach was found to be valid and accounted for more variance in differentiating pain‐related and non‐pain‐related states than did a detailed time‐consuming fine‐grained approach.

A Review of Pain Prevalence in Alzheimer's, Vascular, Frontotemporal and Lewy Body Dementias

BACKGROUND

Numerous studies have reported on pain in dementia. It has been hypothesized that pain perception differs between dementia subtypes, and therefore, the prevalence of pain differs between dementia subtypes. However, there remains a paucity of evidence on the differences in the prevalence of pain in different dementia subtypes. This review aimed to determine the prevalence of pain for the major dementia subtypes: Alzheimer's disease (AD), vascular dementia (VaD), frontotemporal dementia (FTD) and dementia with Lewy bodies (DLB).

SUMMARY

We found 10 studies that met our inclusion criteria. Most of these studies reported on AD; studies reporting the prevalence of pain in people with DLB were scarce, and for FTD, we found no studies. The sample-weighted prevalence of pain could only be calculated for AD, VaD and mixed dementia: AD 45.8% (95% confidence interval, CI: 33.4-58.5%), VaD 56.2% (95% CI: 47.7-64.4%) and mixed dementia 53.9% (95% CI: 37.4-70.1%).

KEY MESSAGES

Studies investigating the prevalence of pain in dementia subtypes were scarce; however, we found a high prevalence of pain in dementia without significant differences between the dementia subtypes. More studies are required to draw firm conclusions on the differences in the prevalence of pain between dementia subtypes.

'There's a Catch-22' - The complexities of pain management for people with advanced dementia nearing the end of life: A qualitative exploration of physicians' perspectives

BACKGROUND

Pain management is a cornerstone of palliative care. The clinical issues encountered by physicians when managing pain in patients dying with advanced dementia, and how these may impact on prescribing and treatment, are unknown.

AIM

To explore physicians' experiences of pain management for patients nearing the end of life, the impact of these on prescribing and treatment approaches, and the methods employed to overcome these challenges.

DESIGN

Qualitative, semi-structured interview study exploring barriers to and facilitators of pain management, prescribing and treatment decisions, and training needs. Thematic analysis was used to elicit key themes.

SETTING/PARTICIPANTS

A total of 23 physicians, responsible for treating patients with advanced dementia approaching the end of life, were recruited from primary care ( n = 9), psychiatry ( n = 7) and hospice care ( n = 7).

RESULTS

Six themes emerged: diagnosing pain, complex prescribing and treatment approaches, side effects and adverse events, route of administration, importance of sharing knowledge and training needs. Knowledge exchange was often practised through liaison with physicians from other specialities. Cross-speciality mentoring and the creation of knowledge networks were believed to improve pain management in this patient population.

CONCLUSION

Pain management in end-stage dementia is complex, requiring cross-population of knowledge between palliative care specialists and non-specialists, in addition to collateral information provided by other health professionals and patients' families. Regular, cost- and time-effective mentoring and ongoing professional development are perceived to be essential in empowering physicians to meet clinical challenges in this area.

Can an observational pain assessment tool improve time to analgesia for cognitively impaired older persons? A cluster randomised controlled trial

OBJECTIVE

The primary objective of the study was to measure the impact of an observational pain assessment dementia tool on time from ED arrival to first dose of analgesic medicine.

METHODS

A multisite cluster randomised controlled trial was conducted to test the Pain Assessment in Advanced Dementia (PAINAD) tool. Patients aged 65 years or older suspected of a long bone fracture were screened for cognitive impairment using the Six-Item Screening (SIS) tool. Patients scoring 4 or less on SIS (intervention sites) were assessed for pain using PAINAD. Control sites, assessed pain using standard methods. The primary outcome was time to first dose of analgesia and was analysed on an intention-to-treat basis with a sensitivity analysis.

RESULTS

We enrolled 602 patients, of which 323 (54%) were at intervention sites (n=4). The median time to analgesia was 82 min (IQR 45-151 min). There was no statistically significant difference in median time to analgesia for intervention 83 (IQR 48-158 min) and non-intervention 82 min (IQR 41-147 min) sites (p=0.414). After adjusting for age, fracture type, arrival mode and triage category, there remained no significant difference in time to analgesia (HR 0.97, 95% CI 0.80 to 1.17, p=0.74). Of the 602 patients enrolled, 273 actually had cognitive impairment. A sensitivity analysis demonstrated patients at intervention sites received analgesia 13 min sooner (90 vs 103 min, p=0.91).

CONCLUSION

Use of the PAINAD was not associated with a shorter time to analgesia, although there was a clinically important but non-significant improvement in the cognitively impaired patient group. Further research is needed to address this clinically important and complex issue.

Prevalence of Pain in Nursing Home Residents: The Role of Dementia Stage and Dementia Subtypes

OBJECTIVES

To study pain prevalence, pain type, and its pharmacological treatment in Dutch nursing home residents in relation to dementia subtype and dementia severity.

DESIGN

Data were collected as part of the PAINdemiA study, an observational cross-sectional study conducted between May 2014 and December 2015.

SETTING

Ten nursing homes in the Netherlands.

PARTICIPANTS

A total of 199 nursing home residents in various stages of dementia.

MEASUREMENTS

We collected data on pain (by observation: MOBID-2 Pain Scale and by self-report scales), pain type, pain medication, dementia subtype, dementia severity (GDS), and demographic features.

RESULTS

In the whole sample, the prevalence of pain was 43% (95% confidence interval 36%-50%) using the MOBID-2 Pain Scale. Regardless of regularly scheduled analgesics, approximately one-third of the residents with pain suffered from moderate to severe pain. Pain assessment with the MOBID-2 Pain Scale showed no difference in pain between dementia subtypes, but residents with more severe dementia experienced pain more often than those with less severe dementia (27% vs 15%). The prevalence of self-reported pain was significantly higher in residents with vascular dementia (VaD) (54%) compared with those with Alzheimer disease (18%) and other dementia subtypes (14%). Nociceptive pain was the predominant type of pain (72%) followed by mixed pain (25%). Acetaminophen was the most prescribed analgesic (80%).

CONCLUSION

Most of the participating nursing home residents had no pain; however, pain was observed more often in residents with severe dementia, whereas residents in the early stages of VaD self-reported pain more often that those with other dementia subtypes. As one-third of the residents with clinically relevant pain had moderate to severe pain regardless of using pain medication, more focus should be on how pain management could use more tailored approaches and be regularly adjusted to individual needs.

Exploring healthcare assistants' role and experience in pain assessment and management for people with advanced dementia towards the end of life: a qualitative study

BACKGROUND

Pain assessment and management are key aspects in the care of people with dementia approaching the end of life but become challenging when patient self-report is impaired or unavailable. Best practice recommends the use of observational pain assessments for these patients; however, difficulties have been documented with health professionals' use of these tools in the absence of additional collateral patient knowledge. No studies have explored the role, perspectives and experiences of healthcare assistants in pain assessment and management in dementia; this study provides insight into this important area.

METHODS

A qualitative approach was adopted, using key informant interviews with healthcare assistants caring for people with advanced dementia approaching the end of life in hospice, nursing home and acute care settings. Thematic analysis was the analytic approach taken to interpretation of interview data. Data were collected between June 2014 and September 2015.

RESULTS

Fourteen participants took part in the study. Participants' average length of caring experience was 15.4 years and most were female. Three key themes emerged: recognising pain, reporting pain, and upskilling. Participants were often the first to notice obvious causes of pain and to detect changes in patient norms which signified hidden causes of pain. Comprehensive knowledge of resident norms enabled participants to observe for behavioural and nonverbal indicators of pain and distinguish these from non-pain related behaviours. Pain reporting was heavily impacted by relationships with professional staff and the extent to which participants felt valued in their role. Positive relationships resulted in comprehensive pain reports; negative relationships led to perfunctory or ambiguous reporting. Participants emphasised a desire for further training and upskilling, including in the use and reporting of basic pain tools.

CONCLUSIONS

Healthcare assistants are frontline staff who have a key role in direct patient care, spending a considerable amount of time with patients in comparison to other health professionals. These staff are often first to notice changes in patients that may signify pain and to alert professional staff. However, to ensure the quality of these reports, further efforts must be made in reversing stigma attached to this role and in upskilling these members of the healthcare team.

Polypharmacy and inappropriate medication use in patients with dementia: an underresearched problem

Multimorbidity and polypharmacy are increasingly prevalent across healthcare systems and settings as global demographic trends shift towards increased proportions of older people in populations. Numerous studies have demonstrated an association between polypharmacy and potentially inappropriate prescribing (PIP), and have reported high prevalence of PIP across settings of care in Europe and North America and, as a consequence, increased risk of adverse drug reactions, healthcare utilization, morbidity and mortality. These studies have not focused specifically on people with dementia, despite the high risk of adverse drug reactions and PIP in this patient cohort. This narrative review considers the evidence currently available in the area, including studies examining prevalence of PIP in older people with dementia, how appropriateness of prescribing is assessed, the medications most commonly implicated, the clinical consequences, and research priorities to optimize prescribing for this vulnerable patient group. Although there has been a considerable research effort to develop criteria to assess medication appropriateness in older people in recent years, the majority of tools do not focus on people with dementia. Of the limited number of tools available, most focus on the advanced stages of dementia in which life expectancy is limited. The development of tools to assess medication appropriateness in people with mild to moderate dementia or across the full spectrum of disease severity represents an important gap in the research literature and is beginning to attract research interest, with recent studies considering the medication regimen as a whole, or misprescribing, overprescribing or underprescribing of certain medications/medication classes, including anticholinergics, psychotropics, antibiotics and analgesics. Further work is required in development and validation of criteria to assess prescribing appropriateness in this vulnerable patient population, to determine prevalence of PIP in large cohorts of people with the full spectrum of dementia variants and severities, and to examine the impact of PIP on health outcomes.

Staff Distress Improves by Treating Pain in Nursing Home Patients With Dementia: Results From a Cluster-Randomized Controlled Trial

CONTEXT

Most people with dementia develop neuropsychiatric symptoms (NPSs), which are distressing for their carers. Untreated pain may increase the prevalence and severity of NPSs and thereby staff burden.

OBJECTIVES

We investigated the association between NPSs and the impact of individual pain treatment on distress in nursing home staff.

METHODS

Nursing home (NH) units were cluster-randomized to an intervention group (33 NH units; n = 175) or control group (27 NH units; n = 177). Patients in the intervention group received individual pain treatment for eight weeks, followed by a four-week washout period; control groups received care as usual. Staff informants (n = 138) used the Neuropsychiatric Inventory-NH version (including caregiver distress) as primary outcome to assess their own distress. Other outcomes were pain (Mobilization-Observation-Behavior-Intensity-Dementia-2 Pain Scale) and cognitive functioning (Mini-Mental State Examination).

RESULTS

Using hierarchical regression analysis, all NPS items at baseline were associated with staff distress (P < 0.01) apart from euphoria; agitation had the largest contribution (β = 0.24). Using mixed models, we found significantly lower staff distress in the intervention group compared to the control group. Moreover, we also found significantly reduced distress in the control group, and there were still effects in both groups throughout the washout period.

CONCLUSION

Individual pain treatment reduced staff distress in the intervention group compared to control group especially in regard to agitation-related symptoms and apathy. Furthermore, our results indicated a multifactorial model of staff distress, in which enhanced knowledge and understanding of NPSs and pain in people with advanced dementia may play an important role.

Differences in analgesic use in community-dwelling persons with and without Alzheimer's disease

BACKGROUND

There are conflicting findings about analgesic use among persons with cognitive impairment compared to cognitively intact older persons. The objective of our study was to investigate the prevalence of analgesic use in community-dwelling persons with and without Alzheimer's disease (AD), within six months after AD diagnosis and to find out factors associated with the use of analgesics and specific analgesic groups.

METHOD

We utilized data from register based MEDALZ (Medication use and Alzheimer's disease) cohort consisting of all community-dwelling persons diagnosed with AD during 2005-2011 in Finland and their matched comparison persons without AD. Altogether, 67,215 persons with AD and one comparison person for each case were included. Drug use data were collected from the Prescription Register and comorbidities from Special Reimbursement and Hospital Discharge Registers.

RESULTS

Statistically significant (p < 0.001) yet mostly small differences were found for analgesics use: analgesics were used by 34.9% and 33.5% of persons with and without AD, respectively. Paracetamol was the most frequently used analgesic both among persons with (25.0%) and without AD (19.1%). Persons with AD used less frequently NSAIDs (Nonsteroidal Anti-inflammatory Drugs) (13.2% vs. 17.3%) and mild opioids (5.0% vs. 7.1%), while the use of strong opioids was more common in comparison to persons without AD (1.3% vs. 1.1%, respectively). Analgesic users were more likely women, aged ≥80 years, had asthma/COPD, cardiovascular disease, diabetes, cancer, hip fracture, osteoporosis, rheumatoid arthritis, and lower socioeconomic position.

CONCLUSION

Further studies are needed to evaluate the adequateness of pain relief in older persons with and without AD.

SIGNIFICANCE

Persons with Alzheimer's disease (AD) used more frequently paracetamol and less frequently NSAIDs and mild opioids. A decreasing trend of NSAID use was observed among persons with AD during the study period.
