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

Improving Safety and Satisfaction in the Safety Monitoring Unit

ABSTRACT

BACKGROUND: The safety monitoring unit (SMU) is a 4-bed unit designated for patients who require continual observation. Most experience some form of dementia, and agitation and aggression are not uncommon. When deescalation techniques do not work, request for help may be necessary. Referred to as Security Alert: Behavioral Assist (SABA), this system-wide message requires response from designated personnel. An increase in SABA events prompted this quality improvement project. METHODS: A survey sent to all unit staff members identified a need for specialized training on the care and management of SMU patients. Education on dementia care and deescalation techniques was provided by a certified dementia specialist and a psychiatry advanced practice registered nurse. Staff expressed a need for defined SMU admission criteria and the establishment of patient care guidelines. Patient care guidelines were developed. A structured schedule was implemented, and dedicated staff were hired to provide familiarity for patients. RESULTS: A postproject survey indicated a nonsignificant increase in staff satisfaction. Security Alert: Behavioral Assist events in the SMU decreased from an average of 3.6 to 1.75 episodes per month. CONCLUSION: Caring for SMU patients creates unique challenges to staff. Staff confidence and satisfaction were higher after implementing new SABA policies. This project could be replicated on similar units with ongoing leadership support and staff education.

Pain Prevalence and Pain Management in Nursing Home Residents With Cognitive Impairment. Results From Five Multicenter Cross-Sectional Surveys in Germany Between 2014 and 2018

BACKGROUND

Pain management depends on continuous pain assessment and a pain concept. In particular, pain assessment and treatment are major challenges for nursing home residents (NHR) with cognitive impairment (CI). Many caregivers often lack the knowledge to recognize and appropriately treat pain in this vulnerable group. Little is known about the proportion of NHR who are fundamentally dependent on external assessment for pain due to CI.

OBJECTIVE

The aim of the study was to determine pain prevalence and management among NHR with and without CI. A second objective was to determine the proportion of NHR who are dependent on external assessment for pain.

METHODS

Information on pain was collected from 3,437 NHR in multicenter cross-sectional surveys in 51 German nursing homes between 2014 and 2018. The presence of current pain in one-to-one interviews was determined as well as dependencies on third-party information, number of daily pain recordings, and administration of medication for pain. The analysis included a contingency table and log regression analyses.

RESULTS

Pain prevalence was 24.9% among NHR with severe CI and 40.4% among NHR without CI. Overall, 19.8% of all NHRs relied on a third-party assessment of pain. Significantly, NHR with severe CI were less likely to be classified as having pain (OR 0.51), to be assessed for pain several times a day (OR 0.53) or to receive pain medication (OR 0.55) compared with NHR without CI. No influence on pain management was shown for the type of pain assessment.

CONCLUSIONS

The study provides evidence of significant deficits in pain management among NHR with moderate and severe CI in nursing homes in Germany. NHR with moderate and severe CI are significantly less likely to be observed for pain or classified as pain sufferers and receive significantly less pain medication than NHR without CI. Intensive training of staff on pain management of NHR with severe CI is recommended.

Determinants of received care time among Finnish home care clients and assisted living facility residents: a time-motion study

BACKGROUND

Ageing populations and care workforce shortages across Europe are causing challenges for care services for older people. Therefore, it is paramount that limited care resources are allocated optimally, based on the clients' care needs. Multiple functioning-related factors have been identified that determine the amount of care time clients receive, while organizational and other factors remain largely unexplored. The aim was to examine how various individual and organizational factors are associated with clients' received care time in different care settings.

METHODS

Cross-sectional observational study design with data from time and motion study, registers, and surveys was used. In total, 1477 home care clients and 1538 residents from assisted living facilities with 24/7 service participated, from 61 Finnish care units. Linear mixed-effect modeling was used to examine the association between individual and organizational-level variables and received care time.

RESULTS

Physical functioning was the strongest predictor of received care time in both care settings. In home care, greater pain, more unstable health, and higher team autonomy were associated with increased care time. In assisted living, depressive mood and higher staffing level of the organization were associated with care time. Clients who received informal care also received significantly more care time from nurses in both care settings.

CONCLUSIONS

Physical functioning was the main driver of received care time. Interventions that maintain or improve physical functioning can help restrain the growing need of care resources, although it is important to ensure that each client receives care according to their holistic care needs.

Psychometric of the Persian version of Quality of Life in Late-Stage Dementia (QUALID) in the elderly with Alzheimer's disease

BACKGROUND

Improving the quality of life (QoL) is a significant healthcare priority, and it is an important health outcome for elderly individuals with Alzheimer's disease. Quality of Life in Late-Stage Dementia (QUALID) is a specific scale used to measure the QoL in elderly individuals with Alzheimer's. So far, limited quantitative research has been conducted on the psychometric properties of this scale.

AIMS

This study was conducted to translate the QUALID Scale into Persian and evaluate its psychometric properties among family and professional caregivers of elderly individuals with Alzheimer's disease in Tehran.

METHODS

A cross-sectional methodological study was conducted among family and professional caregivers of elderly individuals with Alzheimer's in Tehran, Iran in 2022. The questionnaire was translated into Persian using the forward-backward method. Face and content validity were assessed. Additionally, construct validity was examined using exploratory factor analysis (EFA) with Equamax rotation (n=210) and confirmatory factor analysis (CFA) (n=155). Cronbach's alpha and interclass correlation coefficient (ICC) were estimated to determine reliability.

RESULTS

A total of 365 caregivers with a mean age of 14.18±42.60 years participated in this study. In the face and content validity phase, all 11 items were retained. To determine the construct validity, two factors were extracted in the EFA phase, including behavioural signs of discomfort and behavioural signs of social interaction. The findings of the CFA also indicated that all goodness of fit indices supported the final model. The Cronbach's alpha was excellent for both factors (0.814), and the ICC was calculated as 0.98.

CONCLUSION

Based on the findings of this study, it can be concluded that the Persian version of the QUALID Scale has sufficient validity and reliability for measuring the QoL in elderly Iranian individuals with Alzheimer's.

Longitudinal associations between subjective cognitive impairment, pain and depressive symptoms in home-dwelling older adults: Modelling within-person effects

OBJECTIVES

Cognitive impairment, pain and depressive symptoms are common and interrelated factors in older adults. However, the directionality and specificity of their association remains unclarified. This study explored whether these factors prospectively increase reciprocal risk and examined the longitudinal association between these factors and quality of life (QoL).

METHODS

This study used longitudinal data from The Older Persons and Informal Caregivers Survey Minimal Data Set (TOPICS-MDS; the Netherlands). Older adults self-reported cognitive impairment, pain, depressive symptoms and QoL at baseline and after 6 and 12 months of follow-up. The Random Intercept Cross-Lagged Panel Model was used to assess the prospective association between the three factors, while a multilevel linear regression analysis in a two-level random intercept model was used to examine the longitudinal associations between the three factors and QoL at the within-person level.

RESULTS

The data of 11,582 home-dwelling older adults with or without subjective cognitive impairment were analysed. At the within-person level, pain at 6 months was associated with subsequent depressive symptoms (β = 0.04, p = 0.024). The reverse association from depression to pain, and longitudinal associations between pain and subjective cognitive impairment and between depressive symptoms and subjective cognitive impairment were non-significant. Pain, depressive symptoms and subjective cognitive impairment showed a significant association with poor QoL 6 months later.

CONCLUSIONS

A directional relationship was observed from pain to depressive symptoms. Pain reduction holds a potential benefit in the prevention of depressive symptoms, ultimately optimising the QoL of older adults.

Examining pain, function, behavioral symptoms and associations with engagement in meaningful activity for residents with dementia in assisted living

OBJECTIVES

The purpose of this study was to examine factors associated with engagement in meaningful activity among residents with dementia in assisted living. We hypothesized that greater functional independence, less pain, and lower behavioral and psychological symptom severity would be associated with higher engagement in meaningful activity after controlling for residents' age, gender, comorbidities, and cognition. Understanding factors associated with engagement in meaningful activity can help to inform strategies for optimizing engagement among residents with dementia in assisted living.

METHOD

This descriptive study used baseline data from a randomized controlled trial, Meaningful Activity for Managing Behavioral Symptoms of Distress (MAC-4-BSD). Linear regression was used to examine factors associated with engagement in meaningful activity.

RESULTS

A total of 71 residents from 5 assisted living settings were included in the sample. Most participants were female (n = 52, 73%), White (n = 62, 87%), and mean age was 85 years old (SD = 8.2). Controlling for age, gender, comorbidities, and cognition, pain was significantly associated with engagement in meaningful activity (b= -2.09, p < 0.05). There were no associations found between function and behavioral symptoms with engagement in meaningful activity.

CONCLUSION

Findings from this study show that pain is a significant factor that is negatively associated with residents' engagement in meaningful activity. Ongoing research is needed to help improve pain management for residents with dementia in assisted living and support their engagement in meaningful activity.

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.

Identifying Residents Who May Benefit from an Analgesic Review: Applying Analgesic Indicators in Residential Aged Care Services

BACKGROUND

Ensuring safe and effective analgesic use in residential aged care services is important because older adults are susceptible to analgesic-related adverse drug events (ADEs).

OBJECTIVE

The aim of this study was to identify the proportion and characteristics of residents of aged care services who may benefit from analgesic review based on indicators in the 2021 Society for Post-Acute and Long-Term Care Medicine (AMDA) Pain Management Guideline.

METHODS

Cross-sectional analyses of baseline data from the Frailty in Residential Sector over Time (FIRST) study (N = 550 residents) across 12 South Australian residential aged care services in 2019 were conducted. Indicators included the proportion of residents who received > 3000 mg/day of acetaminophen (paracetamol), regular opioids without a documented clinical rationale, opioid doses > 60 mg morphine equivalents (MME)/day, more than one long-acting opioid concurrently, and a pro re nata (PRN) opioid on more than two occasions in the previous 7 days. Logistic regression was performed to investigate factors associated with residents who may benefit from analgesic review.

RESULTS

Of 381 (69.3%) residents charted regular acetaminophen, 176 (46.2%) were charted > 3000 mg/day. Of 165 (30%) residents charted regular opioids, only 2 (1.2%) had no prespecified potentially painful conditions in their medical record and 31 (18.8%) received > 60 MME/day. Of 153 (27.8%) residents charted long-acting opioids, 8 (5.2%) received more than one long-acting opioid concurrently. Of 212 (38.5%) residents charted PRN opioids, 10 (4.7%) received more than two administrations in the previous 7 days. Overall, 196 (35.6%) of 550 residents were identified as potentially benefiting from analgesic review. Females (odds ratio [OR] 1.87, 95% confidence interval [CI] 1.20-2.91) and residents with prior fracture (OR 1.62, 95% CI 1.12-2.33) were more likely to be identified. Observed pain (OR 0.50, 95% CI 0.29-0.88) was associated with a lower likelihood of being identified compared with residents with no observed pain. Overall, 43 (7.8%) residents were identified based on opioid-related indicators.

CONCLUSIONS

Up to one in three residents may benefit from a review of their analgesic regimen, including 1 in 13 who may benefit from a specific review of their opioid regimen. Analgesic indicators represent a new approach to target analgesic stewardship interventions.

[Postoperative pain experience after proximal femur fracture in dementia]

BACKGROUND

The present study aimed to assess the postoperative pain experience in cognitive deficit patients with special reference to sensory or affective pain quality.

METHODS

Nineteen patients with normal cognition up to cognitive impairments according to the DemTect screening-tool were studied regarding their postoperative pain experience after proximal femur fracture. The numerical rating scale (NRS), the cognitive DemTect questionnaire, the pain sensation questionnaire (SES), and a quantitative sensory test (QST) were used as examination instruments.

RESULTS

The mean ± SD age of the patients was 83.8 ± 10.0 years. Of the 19 patients, 6 (31.6%) had normal cognitive abilities. In 4 patients (21.1%) there were indications of mild cognitive impairments, and in 9 patients (47.4%) the suspicions of the presence of dementia arose. The mean postoperative pain intensity (NRS) was 4.0 (1.6). With comparable analgesic therapy, the reported pain intensities did not differ between the three patient groups with different cognitive impairments and the first three postoperative treatment days. There were no statistically significant differences between the groups for the sensory or affective total scores of the pain sensation scale. The QST parameters deep pain (PPT), superficial mechanical pain after needle stimulation (MPT), and the superficial sensitivity to light touch stimuli (MDT) showed a significantly increased sensitivity of the operated side. For the sensation of vibration (VDT) no differences between operated and healthy extremities could be proven.

DISCUSSION

The postoperative pain experience does not differ between patients with normal and limited cognition. The quantitative sensory testing showed mechanical hyperalgesia in the operated area. The study points to the importance of adequate postoperative pain management even in those with dementia.

Process of pain assessment in people with dementia living in nursing homes: a scoping review protocol

INTRODUCTION

Pain is a common symptom in people with dementia; untreated, it reduces quality of life and causes suffering. People with dementia living in nursing homes most often have dementia in moderate to severe stages. The cognitive impairment, including language and communication difficulties, challenges pain assessment. Since pain is a subjective experience, self-reporting is the gold standard of assessment methods. Healthcare professionals are advised to help people with dementia communicate about their pain. The proposed scoping review is the first step in the development of a systematic pain assessment model for people with dementia living in nursing homes. The scoping review aims to identify, categorise and summarise knowledge on how pain assessment processes in this population are described in the literature, with a special focus on self-reporting.

METHODS AND ANALYSIS

The scoping review will be conducted following the six-stage framework developed by Arksey and O'Malley, in addition to recent methodological developments. Systematic searches in CINAHL, Embase, Medline and PsycInfo will be conducted. The protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklists, and the scoping review will adhere to the PRISMA-ScR checklist. The review will include research that concerns assessment of pain in people with dementia living in nursing homes. Studies will be evaluated for quality and ethical standards. The analysis process will follow Bradbury-Jones et al's PAGER framework. Patterns will be formed using thematic analysis. An overview of advances, gaps, evidence for practice and research recommendations associated with each pattern will be prepared. The research questions and results will be presented to and discussed in a reference group comprising nursing home residents, relatives, healthcare professionals and nursing home managers.

ETHICS AND DISSEMINATION

The scoping review aims to collect and summarise data from available publications and does not require ethical approval. The final manuscript will be submitted to a peer-reviewed, open-access journal. REGISTRATION IN OPEN SCIENCE FRAMEWORK: https://osf.io/8kaf5/.

Correlates of Opioid Use Among Ontario Long-Term Care Residents and Variation by Pain Frequency and Intensity: A Cross-sectional Analysis

Background

Chronic non-cancer pain is common among older residents of long-term care (LTC) homes and often poorly recognized and treated. With heightened concerns regarding opioid prescribing in recent years, it is important to examine the current prevalence of opioid use and its association with resident characteristics to help identify those potentially at risk of medication harms as well as suboptimal pain management.

Objectives

The aims were to estimate the prevalence and correlates of opioid use among non-palliative LTC residents and explore variation in opioid prevalence and correlates across strata defined by pain frequency and intensity.

Methods

We conducted a population-based cross-sectional study of all older (aged > 65 years) LTC residents (excluding those with cancer or receiving palliative care) in Ontario, Canada during 2018–2019. Health administrative databases were linked with standardized clinical assessment data to ascertain residents’ health and pain characteristics and their opioid and other medication use. Modified Poisson regression models estimated unadjusted and adjusted associations between residents’ characteristics and opioid use, overall and across strata capturing pain frequency and intensity.

Results

Among 75,020 eligible residents (mean age 85.1 years; 70% female), the prevalence of opioid use was 18.5% and pain was 29.4%. Opioid use ranged from 12.2% for residents with no current pain to 55.7% for those with severe pain. In adjusted models, residents newly admitted to LTC (adjusted risk ratio [aRR] = 0.60, 95% confidence interval [CI] 0.57–0.62) and with moderate to severe cognitive impairment (aRR = 0.69, 95% CI 0.66–0.72) or dementia (aRR = 0.76, 95% CI 0.74–0.79) were significantly less likely to receive an opioid, whereas residents with select conditions (e.g., arthritis, aRR = 1.37, 95% CI 1.32–1.41) and concurrently using gabapentinoids (aRR = 1.80, 95% CI 1.74–1.86), benzodiazepines (aRR = 1.33, 95% CI 1.28–1.38), or antidepressants (aRR = 1.31, 95% CI 1.27–1.35) were significantly more likely to receive an opioid. The associations observed for residents newly admitted, with dementia, and concurrently using gabapentinoids, benzodiazepines, or antidepressants were largely consistent across all pain strata.

Conclusions

Our findings describe resident sub-groups at potentially higher risk of adverse health outcomes in relation to both opioid use and non-use. LTC clinical and policy changes informed by research are required to ensure the appropriate recognition and management of non-cancer pain in this setting.

Efficacy of non-pharmacological interventions to reduce pain in people with dementia: A systematic review and meta-analysis

AIMS AND OBJECTIVES

To identify the efficacy of non-pharmacological interventions designed to reduce pain in people with dementia.

BACKGROUND

Pain is prevalent among patients with dementia but frequently remains untreated. Although non-pharmacological interventions have been used to reduce pain in people with dementia, the efficacy of these interventions for pain management in people with dementia has not been thoroughly synthesised.

DESIGN

Systematic review and meta-analysis.

METHODS

The study was conducted in accordance with PRISMA guidelines and Cochrane criteria for systematic reviews. A comprehensive search was performed using the Academic Search Complete, CINAHL, Cochrane Library, EMBASE, MEDLINE, PubMed, OVID and Web of Science databases, from databases inception to 13 March 2022. The modified Cochrane risk-of-bias tool (ROB-2) was used to evaluate the methodological quality of each included study. Standardised mean differences (SMDs) with 95% confidence intervals (CIs) were synthesised using a random-effects model to assess the efficacy of non-pharmacological interventions for reducing pain in people with dementia (using Stata 16.0).

RESULTS

The final analysis assessed 12 studies, including 989 persons with dementia. Non-pharmacological interventions were found to reduce pain in 4-8 weeks after the interventions (SMD: -0.32; 95% CI: -0.62 to -0.02). However, the effects of intervention frequency and patient age remain unknown.

CONCLUSIONS

Non-pharmacological interventions are effective for reducing pain in people with dementia. Further investigations remain necessary to explore the effectiveness of specific non-pharmacological therapies for pain reduction in people with dementia (e.g. aromatherapy, play activity, singing or robotic care).

RELEVANCE TO CLINICAL PRACTICE

The findings of this study can guide healthcare practitioners when considering the use of non-pharmacological pain management methods for people with dementia and may improve the implementation of these methods in clinical practice.

PATIENT OR PUBLIC CONTRIBUTIONS

The study suggests non-pharmacological interventions to reduce pain and underlines the relevance of health provider's viewpoints. The types, duration and length of follow-up of non-pharmacological interventions can be offered based on patient's conditions and the standard of clinical practice.

The short-term effect of a modified comprehensive geriatric assessment and regularly case conferencing on neuropsychiatric symptoms in nursing homes: a cluster randomized trial

Aims

To investigate the short-term effect of implementing a modified comprehensive geriatric assessment and regularly case conferencing in nursing homes on neuropsychiatric symptoms.

Background

Neuropsychiatric symptoms are common and may persist over time in nursing home residents. Evidence of effective interventions is scarce.

Design

A parallel cluster-randomised controlled trial.

Methods

The intervention was monthly standardised case conferencing in combination with a modified comprehensive geriatric assessment. The control group received care as usual.

Main outcome measure.

The total score on the short version of the Neuropsychiatric Inventory (NPI-Q, 12-items).

Results

A total of 309 residents at 34 long-term care wards in 17 nursing homes (unit of randomisation) were included. The intervention care units conducted on average two case conference-meetings (range 1–3), discussing a mean of 4.8 (range 1–8) residents. After 3 months, there were no difference of NPI-Q total score between the intervention (-0.4) and the control group (0.5) (estimated mean difference = -1.0, 95% CI -2.4 to 0.5, p = 0.19). There was a difference in favour of the intervention group on one of the secondary outcome measures, the apathy symptoms (-0.5 95% CI: -0.9 to -0.1, p = 0.03).

Conclusion

In this study there were no short-term effect of case conferencing and modified comprehensive geriatric assessments after three months on the total score on neuropsychiatric symptoms. The intervention group had less apathy at 3 months follow-up compared to those receiving care as usual. The findings suggest that a more comprehensive intervention is needed to improve the total Neuropsychiatric symptoms burden and complex symptoms.

Trial registration

Due to delays in the organisation, the study was registered after study start, i.e. retrospectively in Clinicaltrials.gov # NCT02790372 at https://clinicaltrials.gov/; Date of clinical trial registration: 03/06/2016.

Mortality in nursing home residents stratified according to subtype of dementia: a longitudinal study over three years

Background

There are several subtypes of dementia caused by different pathophysiology and with different clinical characteristics. Irrespective subtype, the disease is progressive, eventually leading to the need for care and supervision on a 24/7 basis, often provided in nursing homes (NH). The progression rate and course of the disease might vary according to subtype. The aim of this study was to explore whether the mortality rate for NH residents varied according to the subtype of dementia.

Methods

NH residents were followed from admission to NH over a period of 36 months or until death with annual follow-up examinations. Demographic and clinical data were collected. The diagnosis of dementia and its subtype at baseline (BL) were set according to international accepted criteria. Kaplan-Meier analysis was performed to estimate median survival time. A Cox regression model was estimated to assess the impact of dementia diagnosis and demographic and clinical variables on mortality.

Results

A total of 1349 participants were included. When compared to persons with Alzheimer’s disease (AD), persons with frontotemporal dementia (FTD) and dementia with Lewy bodies or Parkinson’s disease dementia (DLB/PDD) were younger and had more neuropsychiatric symptoms. Median survival for the total sample was 2.3 years (95% confidence interval: 2.2–2.5). When compared to persons with AD, having no dementia or unspecified dementia was associated with higher mortality, while we found similar mortality in other subtypes of dementia. Higher age, male gender, poorer general health, higher dependency in activities of daily living, and more affective symptoms were associated with higher mortality.

Conclusion

Mortality did not differ across the subtypes of dementia, except in persons with unspecified dementia or without dementia, where we found a higher mortality. With a median survival of 2.3 years, NH residents are in the last stage of their lives and care and medical follow-up should focus on a palliative approach. However, identifying the subtype of dementia might help carers to better understand and address neuropsychiatric symptoms and to customize medical treatment.

Algorithm-based pain management for people with dementia in nursing homes

BACKGROUND

People with dementia in nursing homes often experience pain, but often do not receive adequate pain therapy. The experience of pain has a significant impact on quality of life in people with dementia, and is associated with negative health outcomes. Untreated pain is also considered to be one of the causes of challenging behaviour, such as agitation or aggression, in this population. One approach to reducing pain in people with dementia in nursing homes is an algorithm-based pain management strategy, i.e. the use of a structured protocol that involves pain assessment and a series of predefined treatment steps consisting of various non-pharmacological and pharmacological pain management interventions.

OBJECTIVES

To assess the effects of algorithm-based pain management interventions to reduce pain and challenging behaviour in people with dementia living in nursing homes. To describe the components of the interventions and the content of the algorithms.

SEARCH METHODS

We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE, Embase, PsycINFO, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Web of Science Core Collection (ISI Web of Science), LILACS (Latin American and Caribbean Health Science Information database), ClinicalTrials.gov and the World Health Organization's meta-register the International Clinical Trials Registry Portal on 30 June 2021.

SELECTION CRITERIA

We included randomised controlled trials investigating the effects of algorithm-based pain management interventions for people with dementia living in nursing homes. All interventions had to include an initial pain assessment, a treatment algorithm (a treatment plan consisting of at least two different non-pharmacological or pharmacological treatment steps to reduce pain), and criteria to assess the success of each treatment step. The control groups could receive usual care or an active control intervention. Primary outcomes for this review were pain-related outcomes, e.g. the number of participants with pain (self- or proxy-rated), challenging behaviour (we used a broad definition that could also include agitation or behavioural and psychological symptoms assessed with any validated instrument), and serious adverse events.

DATA COLLECTION AND ANALYSIS

Two authors independently selected the articles for inclusion, extracted data and assessed the risk of bias of all included studies. We reported results narratively as there were too few studies for a meta-analysis. We used GRADE methods to rate the certainty of the results.

MAIN RESULTS

We included three cluster-randomised controlled trials with a total of 808 participants (mean age 82 to 89 years). In two studies, participants had severe cognitive impairment and in one study mild to moderate impairment. The algorithms used in the studies varied in the number of treatment steps. The comparator was pain education for nursing staff in two studies and usual care in one study. We judged the risk of detection bias to be high in one study. The risk of selection bias and performance bias was unclear in all studies. Self-rated pain (i.e. pain rated by participants themselves) was reported in two studies. In one study, all residents in the nursing homes were included, but fewer than half of the participants experienced pain at baseline, and the mean values of self-rated and proxy-rated pain at baseline and follow-up in both study groups were below the threshold of pain that may require treatment. We considered the evidence from this study to be very low-certainty and therefore are uncertain whether the algorithm-based pain management intervention had an effect on self-rated pain intensity compared with pain education (MD -0.27, 95% CI -0.49 to -0.05, 170 participants; Verbal Descriptor Scale, range 0 to 3). In the other study, all participants had mild to moderate pain at baseline. Here, we found low-certainty evidence that an algorithm-based pain management intervention may have little to no effect on self-rated pain intensity compared with pain education (MD 0.4, 95% CI -0.58 to 1.38, 246 participants; Iowa Pain Thermometer, range 0 to 12). Pain was rated by proxy in all three studies. Again, we considered the evidence from the study in which mean pain scores indicated no pain, or almost no pain, at baseline to be very low-certainty and were uncertain whether the algorithm-based pain management intervention had an effect on proxy-rated pain intensity compared with pain education. For participants with mild to moderate pain at baseline, we found low-certainty evidence that an algorithm-based pain management intervention may reduce proxy-rated pain intensity in comparison with usual care (MD -1.49, 95% CI -2.11 to -0.87, 1 study, 128 participants; Pain Assessment in Advanced Dementia Scale-Chinese version, range 0 to 10), but may not be more effective than pain education (MD -0.2, 95% CI -0.79 to 0.39, 1 study, 383 participants; Iowa Pain Thermometer, range 0 to 12). For challenging behaviour, we found very low-certainty evidence from one study in which mean pain scores indicated no pain, or almost no pain, at baseline. We were uncertain whether the algorithm-based pain management intervention had any more effect than education for nursing staff on challenging behaviour of participants (MD -0.21, 95% CI -1.88 to 1.46, 1 study, 170 participants; Cohen-Mansfield Agitation Inventory-Chinese version, range 7 to 203). None of the studies systematically assessed adverse effects or serious adverse effects and no study reported information about the occurrence of any adverse effect. None of the studies assessed any of the other outcomes of this review.

AUTHORS' CONCLUSIONS

There is no clear evidence for a benefit of an algorithm-based pain management intervention in comparison with pain education for reducing pain intensity or challenging behaviour in people with dementia in nursing homes. We found that the intervention may reduce proxy-rated pain compared with usual care. However, the certainty of evidence is low because of the small number of studies, small sample sizes, methodological limitations, and the clinical heterogeneity of the study populations (e.g. pain level and cognitive status). The results should be interpreted with caution. Future studies should also focus on the implementation of algorithms and their impact in clinical practice.
