Comorbid Dementia and Cancer in Residents of Nursing Homes: Secondary Analyses of a Cross-Sectional Study

Good Death and Quality of End-of-Life Care in Patients with Coexisting Cancer and Dementia: Perspective of Bereaved Families

Background

Patients with coexisting cancer and dementia often have complex health care needs and face challenges in achieving a good death.

Objectives

To evaluate good death achievement and end-of-life (EOL) care in patients with coexisting cancer and dementia from the perspective of bereaved families.

Design

Cross-sectional nationwide postal survey.

Setting/Subjects

Bereaved families of patients with cancer who died in hospice and palliative care units across Japan.

Measurements

Bereaved families completed an anonymous, self-reported questionnaire. Their perspective on achieving a good death was assessed using the Good Death Inventory (GDI) (total score: 18-126). The Revised Care Evaluation Scale-short version (CES2) was used to assess EOL care (total score: 10-60). We examined the Brief Grief Questionnaire (BGQ) (total score: 0-10) and Patient Health Questionnaire 9 (PHQ9) (total score: 0-27).

Results

Data from 670 participants were analyzed, including 83 (12.4%) bereaved families of patients with coexisting cancer and dementia. No statistical differences were observed in the total GDI score for 18 items (dementia comorbidity vs. nondementia comorbidity groups, mean ± standard deviation, respectively, 78.4 ± 17.7 vs. 80.0 ± 15.5, adjusted [adj] P = 0.186), CES2 score (49.70 ± 9.22 vs. 48.82 ± 8.40, adj P = 0.316), BGQ score (3.40 ± 2.41 vs. 4.36 ± 2.28, adj P = 0.060), and PHQ9 score (4.67 ± 4.71 vs. 5.50 ± 5.37, adj P = 0.788).

Conclusions

GDI, CES2, BGQ, and PHQ9 scores did not differ significantly between groups, regardless of the presence of dementia in hospice and palliative care units. Patients with coexisting cancer and dementia can achieve a good death by high-quality EOL care.

Towards an improved dementia care experience in clinical radiography practice: A state-of-the-art review

INTRODUCTION

The increasing global incidence rate of dementia and associated co/multimorbidity has consequently led to a rise in the number of people with dementia (PwD) requiring clinical radiography care services. This review aims to explore and integrate findings from diverse settings with a focus on the experiences of PwD and stakeholders, towards the development of a holistic approach for dementia care and management within the context of radiography services.

METHOD

An electronic search was performed across the following databases: PUBMED, CINAHL, Medline, SCOPUS, and ScienceDirect for articles published from January 2009 and June 2023. Articles were included if they fulfilled a predefined criteria mainly focused on experiences of PwD and/or other stakeholders when using the radiography services. Data obtained from the included studies were analysed using a result-based convergent synthesis.

RESULT

Eleven studies from diverse settings met the inclusion criteria. A mix of both positive and negative experiences of PwD and stakeholders were reported following visits to radiology and radiotherapy departments were highlighted across settings. The findings were themed around the need for: person-centred care, effective communication, attitudinal changes of staff, specialised and improved clinical environment and inclusion of caregivers for the care of PwD.

DISCUSSION

This study emphasise the critical importance of adopting holistic approaches to caring for PwD. This involves adopting a person-centred approach, actively involving caregivers, effective communication, and adequate training for radiographers to provide quality services, all in dementia-friendly environments.

CONCLUSION

The experiences of various stakeholders highlight the need for a more holistic approach and strategy for the care and management of PwD within the context of the radiography services. This calls for an urgent need for a comprehensive strategy that includes awareness creation of staff to enhance the quality of care and the overall experience for PwD using the radiography services.

Exploring the Holistic Needs of People Living with Cancer in Care Homes: An Integrative Review

Up to 26% of individuals residing in care homes are impacted by cancer. This underscores the importance of understanding the holistic needs of care home residents living with cancer to enhance the quality of their care. The primary objective of this integrative literature review was to consolidate the available evidence concerning the comprehensive needs of people living with cancer in care home settings, providing valuable insights into addressing their diverse needs. An integrative literature review was conducted using a systematic approach. Extensive searches were conducted in three databases, complemented by a thorough examination of grey literature and reference lists of relevant papers. The review focused on literature published between 2012 and 2022. The screening process involved two independent reviewers, with a third reviewer resolving any discrepancies. The review identified twenty research papers that met the eligibility criteria. These papers shed light on three primary themes related to the holistic needs of care home residents with cancer: physical, psychological, and end-of-life needs. Physical needs encompassed pain management, symptom control, and nutrition, while psychological needs involved social support, emotional well-being, and mental health care. End-of-life needs addressed end-of-life care and advance care planning. These themes highlight the multifaceted nature of cancer care in care homes and underscore the importance of addressing residents' holistic needs in a comprehensive and integrated manner. Improving care home education about cancer and integrating palliative and hospice services within this setting are vital for addressing the diverse needs of residents with cancer.

Prevalence and health outcomes in community-dwelling older adults with comorbid cancer and dementia: a longitudinal analysis

OBJECTIVES

To examine health outcomes in community-dwelling older adults with: dementia only, cancer only, and comorbid cancer and dementia.

METHODS

Longitudinal analysis was conducted using data from 2010 to 2016 waves of the Health and Retirement Study. Health outcomes included mortality, limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL), nursing home utilization, hospital stay, homecare use, self-rated health, and out-of-pocket medical expenditure. Panel regression was used for statistical analysis.

RESULTS

The prevalence of comorbid cancer and dementia ranged from 2.56% to 2.97%. Individuals with comorbid cancer and dementia demonstrated a higher likelihood of nursing home utilization and poorer self-rated health but a lower likelihood of hospital stay, homecare use, and out-of-pocket expenditures, compared to the cancer only or dementia only groups. The differences in mortality and ADL and IADL limitations were not statistically significant.

CONCLUSION

Comorbid cancer and dementia predicted longer nursing home utilization and poorer self-rated health. The results help guide care planning for individuals with comorbid cancer and dementia.

Cancer care for people with dementia: Literature overview and recommendations for practice and research

As many countries experience population aging, patients with cancer are becoming older and have more preexisting comorbidities, which include prevalent, age-related, chronic conditions such as dementia. People living with dementia (PLWD) are vulnerable to health disparities, and dementia has high potential to complicate and adversely affect care and outcomes across the cancer trajectory. This report offers an overview of dementia and its prevalence among patients with cancer and a summary of the research literature examining cancer care for PLWD. The reviewed research indicates that PLWD are more likely to have cancer diagnosed at an advanced stage, receive no or less extensive cancer treatment, and have poorer survival after a cancer diagnosis. These cancer disparities do not necessarily signify inappropriately later diagnosis or lower treatment of people with dementia as a group, and they are arguably less feasible and appropriate targets for care optimization. The reviewed research indicates that PLWD also have an increased risk of cancer-related emergency presentations, lower quality processes of cancer-related decision making, accessibility-related barriers to cancer investigations and treatment, higher experienced treatment burden and higher caregiver burden for families, and undertreated cancer-related pain. The authors propose that optimal cancer care for PLWD should focus on proactively minimizing these risk areas and thus must be highly person-centered, with holistic decision making, individualized reasonable adjustments to practice, and strong inclusion and support of family carers. Comprehensive recommendations are made for clinical practice and future research to help clinicians and providers deliver best and equitable cancer care for PLWD and their families.

Characteristics and general practice resource use of people with comorbid cancer and dementia in England: a retrospective cross-sectional study

Background

Cancer and dementia are common in older people and management of the conditions as comorbidities can be challenging, yet little is known about the size or characteristics of this group. We aimed to estimate the prevalence, characteristics and general practice resource usage of people living with both conditions in England.

Methods

Anonymised electronic healthcare records from 391 National Health Service general practices across England using the TPP SystmOne general practice system were obtained from ResearchOne. Data included demographic and clinical characteristics, and general practice healthcare useage (appointments, prescriptions, referrals and secondary care contacts) for people aged 50 and over with a cancer and/or dementia diagnosis consistent with the Quality and Outcomes Framework between 2005 and 2016. Multi-level negative binomial regression was used to analyse the association between having cancer and/or dementia and the number of general practice appointments.

Results

Data from 162,371 people with cancer and/or dementia were analysed; 3616 (2.2%) people were identified as having comorbid cancer and dementia. Of people with cancer, 3.1% also had dementia, rising to 7.5% (1 in 13 people) in those aged 75 and over. Fewer people with both conditions were female (50.7%) compared to those with dementia alone (65.6%) and those with comorbid cancer and dementia were older than those with cancer alone [mean ages 83 (sd = 7), 69 (sd = 12) respectively]. Those with both conditions were less likely to have lung cancer than those with cancer alone (7.5% vs. 10.3%) but more likely to have prostate cancer (20.9% vs. 15.8%). Additional comorbidities were more prevalent for those with both conditions than those with cancer or dementia alone (68.4% vs. 50.2% vs. 54.0%). In the year following the first record of either condition, people with cancer and dementia had 9% more general practice appointments (IRR:1.09, 95% CI:1.01–1.17) than those with cancer alone and 37% more appointments than those with dementia alone (IRR: 1.37, 95% CI: 1.28–1.47).

Conclusions

A significant number of people are living with comorbid cancer and dementia in England. This group have additional comorbidity and higher general practice usage than those with cancer/dementia alone. The needs of this group should be considered in future general practice care planning and research.

Equal receipt of specialized palliative care in breast and prostate cancer: a register study

PURPOSE

There are inequalities in cancer treatment. This study aimed to investigate whether receipt of specialized palliative care (SPC) is affected by typical female and male diagnoses (breast and prostate cancer), age, socioeconomic status (SES), comorbidities as measured by the Charlson Comorbidity Index (CCI), or living arrangements (home vs nursing home residence). Furthermore, we wanted to investigate if receipt of SPC affects the place of death, or correlated with emergency department visits, or hospital admissions.

METHODS

All breast and prostate cancer patients who died with verified distant metastases during 2015-2019 in the Stockholm Region were included (n = 2516). We used univariable and stepwise (forward) logistic multiple regression models.

RESULTS

Lower age, lower CCI score, and higher SES significantly predicted receipt of palliative care 3 months before death (p = .007-p < .0001). Patients with prostate cancer, a lower CCI score, receiving palliative care services, or living in a nursing home were admitted to a hospital or visited an emergency room less often during their last month of life (p = .01 to < .0001). Patients receiving palliative care services had a low likelihood of dying in an acute care hospital (p < .001). Those who died in a hospital were younger, had a lower CCI score, and had received less palliative care or nursing home services (p = .02- < .0001).

CONCLUSION

Age, comorbidities, and nursing home residence affected the likelihood of receiving SPC. However, the diagnosis of breast versus prostate cancer did not. Emergency room visits, hospital admissions, and hospital deaths are registered less often for patients with SPC.

Right at Home: Living with Dementia and Multimorbidities

Dementia is recognised as the biggest health crisis of our time in terms of high personal and social costs and wider impact on health and social care systems. Increases in people living with dementia and multimorbidities presents critical challenges for homecare worldwide. Healthcare systems struggle to provide adequate home-care services, delivering limited care restricted to a single-condition focus. This study explored the experiences and expectations of homecare from the multiple perspectives of people living with dementia and multimorbidities and homecare workers providing support. Findings draw from qualititative semi-structured interviews with people with dementia (n=2), their partners (n=2), other partners or family carers (n=6) and homecare workers (n=26). Three themes are idenfiifed: (a) the preference for and value of home; (b) inadequate homecare provision and enhanced care-burden; (c) limited training and education. Despite continued calls for homecare investment, the focus on reduction in costs hides key questions and further dialogue required exploring how people with dementia can be supported to live independendently and flourish at-home. This study considers these complex experiences and care requirements through the prism of disability and human rights frameworks. This paper concludes with consideration of more recent human social rights debate. We critically dicuss what this may mean for people living with dementia and consider the implications for corequisite policy development to optimise available homecare support.

Do Cognitively Impaired Elderly Patients with Cancer Respond Differently on Self-reported Symptom Scores? A 5-Year Retrospective Analysis

Objectives:

An increasing number of elderly subjects with cancer were admitted to the palliative care unit and they have suffered both distressing symptoms and cognitive impairment. We aim to identify the prevalence of cognitive impairment among elderly cancer patients receiving in-patient palliative care and to examine any difference between patients with cognitive impairment on self-reported symptoms.

Materials and Methods:

Subjects’ age ≥65 admitted to a palliative care unit from 01 September 2015 to 31 August 2020 was included in the study. Exclusion criteria were those with an impaired conscious state, severe cognitive impairment, or language problems that were non-communicable. Variables collected included baseline demographics, cancer diagnosis, cancer stage, mobility state using the modified Barthel index (mBI), and performance status as measured by the palliative performance scale. Cognitive impairment was defined by abbreviated mental test ≤6. Self-reported symptoms scales were measured by the Chinese version of MD Anderson Symptom Inventory and EORTC QLQ C-30 (European Organisation for Research and Treatment of Cancer, Quality of Life Core Questionnaire 30).

Results:

Nine hundred and ninety-one subjects with 1174 admissions were retrieved. Eight hundred and seventy-three admission episodes were included in this study. Three hundred and eight (35%) have cognitive impairment. Cognitively impaired subjects were older, showed worse physical function and performance status, and more often residing in old age homes. Independent predictors of cognitive impairment were age (OR 1.09), mBI (OR 0.96), chair/bed bound state (OR 1.79), and presence of brain metastasis (OR 2.63). They reported lower scores in pain (P < 0.001), distress (P < 0.001), sleep disturbance (P < 0.001) and nausea and vomiting (P = 0.012) in the self-reported symptoms scale.

Conclusion:

Elderly cancer patients with cognitive impairment were older with poorer performance status. They have reported a lower level of pain, distress, and sleep disturbance. Clinicians should be alerted to this phenomenon to tackle the unmet concomitant symptoms.

Cultural and Ethical Barriers to Cancer Treatment in Nursing Homes and Educational Strategies: A Scoping Review

(1) Background: The aging of the population, the increase in the incidence of cancer with age, and effective chronic oncological treatments all lead to an increased prevalence of cancer in nursing homes. The aim of the present study was to map the cultural and ethical barriers associated with the treatment of cancer and educational strategies in this setting. (2) Methods: A systematic scoping review was conducted until April 2021 in MEDLINE, Embase, and CINAHL. All articles assessing continuum of care, paramedical education, and continuing education in the context of older cancer patients in nursing homes were reviewed. (3) Results: A total of 666 articles were analyzed, of which 65 studies were included. Many factors interfering with the decision to investigate and treat, leading to late- or unstaged disease, palliative-oriented care instead of curative, and a higher risk of unjustified transfers to acute care settings, were identified. The educational strategies explored in this context were generally based on training programs. (4) Conclusions: These results will allow the co-construction of educational tools intended to develop knowledge and skills to improve diagnostic and therapeutic decision-making, the consistency of care, and, ultimately, the quality of life of older cancer patients in nursing homes.

Measuring the prevalence of sleep disturbances in people with dementia living in care homes: a systematic review and meta-analysis

Study Objectives

Sleep disturbances are a feature in people living with dementia, including getting up during the night, difficulty falling asleep, and excessive daytime sleepiness and may precipitate a person with dementia moving into residential care. There are varying estimates of the frequency of sleep disturbances, and it is unknown whether they are a problem for the individual. We conducted the first systematic review and meta-analysis on the prevalence and associated factors of sleep disturbances in the care home population with dementia.

Methods

We searched Embase, MEDLINE, and PsycINFO (29/04/2019) for studies of the prevalence or associated factors of sleep disturbances in people with dementia living in care homes. We computed meta-analytical estimates of the prevalence of sleep disturbances and used meta-regression to investigate the effects of measurement methods, demographics, and study characteristics.

Results

We included 55 studies of 22,780 participants. The pooled prevalence on validated questionnaires of clinically significant sleep disturbances was 20% (95% confidence interval, CI 16% to 24%) and of any symptom of sleep disturbance was 38% (95% CI 33% to 44%). On actigraphy using a cutoff sleep efficiency of <85% prevalence was 70% (95% CI 55% to 85%). Staff distress, resident agitation, and prescription of psychotropic medications were associated with sleep disturbances. Studies with a higher percentage of males had a higher prevalence of sleep disturbance.

Conclusions

Clinically significant sleep disturbances are less common than those measured on actigraphy and are associated with residents and staff distress and the increased prescription of psychotropics. Actigraphy appears to offer no benefit over proxy reports in this population.

An Overview of Treating People with Comorbid Dementia: Implications for Cancer Care

With increasing prevalence of both cancer and dementia in the UK, due to an ageing population, oncology healthcare professionals will experience higher numbers of people with both conditions. As dementia is highly heterogeneous and symptoms vary from individual to individual, it presents specific challenges for healthcare professionals, people with dementia and caregivers alike. This overview will describe current theories that explain the association between cancer and dementia, report prevalence rates and highlight the evidence on the impact of having a diagnosis of dementia on outcomes along the cancer pathway from cancer symptom detection to cancer treatment outcomes. It suggests that although prevalence rates of cancer and dementia are typically lower than other comorbidities, people with cancer and dementia have poorer cancer-related outcomes. This includes later stage cancer diagnoses, fewer cancer treatment options and an increased risk of death compared with people who have cancer alone or other comorbid conditions. Considerations for cancer treatment decision making and management are proposed to improve patient experience for this group.

A Stepwise Pharmacist-Led Medication Review Service in Interdisciplinary Teams in Rural Nursing Homes

Background: The provision of responsible medication therapy to old nursing home residents with comorbidities is a difficult task and requires extensive knowledge about optimal pharmacotherapy for different conditions. We describe a stepwise pharmacist-led medication review service in combination with an interdisciplinary team collaboration in order to identify, resolve, and prevent medication related problems (MRPs). Methods: The service included residents from four rural Norwegian nursing homes during August 2016–January 2017. All residents were eligible if they (or next of kin) supplied oral consent. The interdisciplinary medication review service comprised four steps: (1) patient and medication history taking; (2) systematic medication review; (3) interdisciplinary case conference; and (4) follow-up of pharmaceutical care plan. The pharmacist collected information about previous and present medication use, and clinical and laboratory values necessary for the medication review. The nurses collected information about possible symptoms related to adverse drug reactions. The pharmacist conducted the medication reviews, identified medication-related problems (MRPs) which were discussed at case conferences with the responsible physician and the responsible nurses. The main outcome measures were number and types of MRPs, percentage agreement between pharmacists and physicians and factors associated with MRPs. Results: The service was delivered for 151 (94%) nursing home residents. The pharmacist identified 675 MRPs in 146 (97%) medication lists (mean 4.0, SD 2.6, range 0–13). The MRPs most frequently identified concerned ‘unnecessary drug’ (22%), ‘too high dosage’ (17%) and ‘drug interactions’ (16%). The physicians agreed upon 64% of the pharmacist recommendations, and action was taken immediately for 32% of these. We identified no association between the number of MRPs and sex (p = 0.485), but between the number of MRPs, and the number of medications and the individual nursing homes. Conclusion: The pharmacist-led medication review service in the nursing homes was highly successfully piloted with many solved and prevented MRPs in interdisciplinary collaboration between the pharmacist, physicians, and nurses. Implementation of this service as a standard in all four nursing homes seems necessary and feasible. If such a service is implemented, effects related to patient outcomes, interdisciplinary collaboration, and health economy should be studied.

Association of Comorbid Burden and Patient Outcomes of Residents With Dementia in Jordanian Nursing Homes

Medical and psychiatric comorbidity in individuals with dementia is often associated with serious adverse health outcomes. Using a convenience sample of 76 residents with dementia in Jordanian nursing homes, the current study aimed to examine the relationship among comorbid burden, ability to verbally self-report symptoms, severity of dementia, and patient outcomes of pain and agitation. Comorbid burden and ability to verbally self-report symptoms were found to be significant predictors of patient outcomes of pain and agitation. However, the ability to verbally self-report symptoms did not explain the relationship between comorbid burden and patient outcomes. Nurses must understand the impact of comorbid burden and the ability to verbally self-report symptoms regarding pain and agitation in individuals with dementia.

Effects of pain treatment on sleep in nursing home patients with dementia and depression: A multicenter placebo-controlled randomized clinical trial

OBJECTIVE

To investigate the effects of pain treatment on sleep in nursing home (NH) patients with dementia and depression.

METHODS

A multicenter, 2-armed, double-blinded, placebo-controlled, randomized clinical trial conducted between August 2014 and September 2016. One hundred six long-term patients from 47 NHs in Norway with dementia and depression according to the Mini-Mental State Examination and the Cornell Scale for Depression in Dementia were included. Patients received stepwise pain treatment in which those who did not use analgesics were randomized to receive either paracetamol (3 g/day) or placebo tablets; those who already used pain treatment were allocated to buprenorphine transdermal system (max. 10 μg/h/7 days) or placebo transdermal patches. Sleep was assessed continuously for 14 days by actigraphy, 1 week of baseline measurement, and 1 week of ongoing treatment. The following sleep parameters were evaluated: total sleep time, sleep efficiency (SE), sleep onset latency (SOL), wake after sleep onset, early morning awakening (EMA), and number of wake bouts.

RESULTS

In the intervention group (paracetamol/buprenorphine), SE (70%-72%), SOL (32-24 min), and EMA (50-40 min) improved compared with the control group (SE, 70%-67%; SOL, 47-60 min; EMA, 31-35 min). Treatment effects were significant (P < .01, P < .05, and P < .05, respectively).

CONCLUSION

Compared with placebo, pain treatment improved sleep as measured with actigraphy. This implies that sleep, pain, and depression in NH patients should be critically evaluated and that pain treatment should be considered to be a potentially beneficial treatment.

Long-Term Pain Treatment Did Not Improve Sleep in Nursing Home Patients with Comorbid Dementia and Depression: A 13-Week Randomized Placebo-Controlled Trial

Objective: Previous research indicates that pain treatment may improve sleep among nursing home patients. We aimed to investigate the long-term effect of pain treatment on 24-h sleep patterns in patients with comorbid depression and dementia.

Design: A 13-week, multicenter, parallel-group, double-blind, placebo-controlled randomized clinical trial conducted between August 2014 and September 2016.

Setting: Long-term patients from 47 nursing homes in Norway.

Participants: We included 106 patients with comorbid dementia and depression according to the Mini Mental Status Examination (MMSE) and the Cornell Scale for Depression in Dementia (CSDD).

Intervention: Patients who were not using analgesics were randomized to receive either paracetamol (3 g/day) or placebo tablets. Those who already received pain treatment were randomized to buprenorphine transdermal system (maximum 10 μg/h/7 days) or placebo transdermal patches.

Measurements: Sleep was assessed continuously for 7 days by actigraphy, at baseline and in week 13. Total sleep time (TST), sleep efficiency (SE), sleep onset latency (SOL), wake after sleep onset (WASO), early morning awakening (EMA), and number of wake bouts (NoW) were evaluated. In addition, daytime total sleep time (DTS) was estimated. Pain was assessed with Mobilization-Observation-Behavior-Intensity-Dementia-2 Pain Scale (MOBID-2).

Results: The linear mixed model analyses for TST, SE, SOL, WASO, EMA, NoW and DTS showed no statistically significant differences between patients who received active pain treatment and those who received placebo. Post hoc subgroup analyses showed that there were no statistically significant differences between active treatment and placebo from baseline to week 13 in patients who were in pain (MOBID-2 ≥ 3) at baseline, or in patients who had poor sleep (defined as SE < 85%) at baseline. Patients who received active buprenorphine showed an increase in TST and SE compared to those who received active paracetamol.

Conclusion: The main analyses showed that long-term pain treatment did not improve sleep as measured with actigraphy. Compared to paracetamol, TST and SE increased among patients who received buprenorphine. This could indicate that some patients had beneficial effects from the most potent pain treatment. However, based on the present findings, long-term pain treatment is not recommended as a strategy to improve sleep. Clinical Trial https://clinicaltrials.gov/ct2/show/NCT02267057.

Clinically significant discrepancies between sleep problems assessed by standard clinical tools and actigraphy

Background

Sleep disturbances are widespread among nursing home (NH) patients and associated with numerous negative consequences. Identifying and treating them should therefore be of high clinical priority. No prior studies have investigated the degree to which sleep disturbances as detected by actigraphy and by the sleep-related items in the Cornell Scale for Depression in Dementia (CSDD) and the Neuropsychiatric Inventory – Nursing Home version (NPI-NH) provide comparable results. Such knowledge is highly needed, since both questionnaires are used in clinical settings and studies use the NPI-NH sleep item to measure sleep disturbances. For this reason, insight into their relative (dis)advantages is valuable.

Method

Cross-sectional study of 83 NH patients. Sleep was objectively measured with actigraphy for 7 days, and rated by NH staff with the sleep items in the CSDD and the NPI-NH, and results were compared. McNemar's tests were conducted to investigate whether there were significant differences between the pairs of relevant measures. Cohen's Kappa tests were used to investigate the degree of agreement between the pairs of relevant actigraphy, NPI-NH and CSDD measures. Sensitivity and specificity analyses were conducted for each of the pairs, and receiver operating characteristics (ROC) curves were designed as a plot of the true positive rate against the false positive rate for the diagnostic test.

Results

Proxy-raters reported sleep disturbances in 20.5% of patients assessed with NPI-NH and 18.1% (difficulty falling asleep), 43.4% (multiple awakenings) and 3.6% (early morning awakenings) of patients had sleep disturbances assessed with CSDD. Our results showed significant differences (p<0.001) between actigraphy measures and proxy-rated sleep by the NPI-NH and CSDD. Sensitivity and specificity analyses supported these results.

Conclusions

Compared to actigraphy, proxy-raters clearly underreported NH patients' sleep disturbances as assessed by sleep items in NPI-NH and CSDD. The results suggest that the usefulness of proxy-rater measures of sleep may be questionable and further research is needed into their clinical value. The results highlight the need for NH staff to acquire and act on knowledge about sleep and sleep challenges among NH patients.
