Pain in dementia

Development and Validation of a Short Version (PAIC6) of the Pain Assessment in Impaired Cognition Scale

BACKGROUND

Observer pain scales are commonly used to assess pain in individuals with impaired cognition. However, nursing staff have highlighted that extremely tight time schedules and increasing workload demands prevent regular use. With the development of a short version of the Pain Assessment in Impaired Cognition (PAIC15), we aimed to reduce implementation barriers in everyday clinical practice.

METHODS

We developed a new 6-item short version (PAIC6) in a first sample (N = 59) and validated its psychometric properties in a second sample (N = 250) of older individuals with cognitive impairments. The item reduction and evaluation involved four steps. First, we used Sample 1 to exclude items based on item quality statistics (e.g., difficulty, reliability). Second, the Partial Credit Model (PCM) was utilised for further reduction using again Sample 1. Third, an expert panel evaluated the preceding steps and suggested a draft short version with six items (PAIC6). Fourth, psychometric properties of the short version were evaluated in the independent Sample 2. Thereafter, the final short version was approved.

RESULTS

The new PAIC6 showed a high correlation with the total scale PAIC15 (r = 0.870), good reliability (Cronbach's α = 0.684), and high convergent construct validity, as observed by a high correlation with the established Pain Assessment in Advanced Dementia (r = 0.602).

CONCLUSIONS

Overall, we developed a valid, reliable, and clinically valuable PAIC6 that allows a more time-efficient pain assessment, by reducing the assessment time from 5 min to approximately 2 min (60% time saving).

SIGNIFICANCE

Observer pain scales are commonly used to assess pain in individuals with impaired cognition. However, nursing staff have highlighted that extremely tight time schedules and increasing workload demands prevent regular use. To address this, we developed PAIC6, a short version of the Pain Assessment in Impaired Cognition 15 (PAIC15). PAIC6 includes six items and takes 2 min for completion after training, realising a 60%-time reduction compared to the original scale while keeping the psychometric quality high.

Dementia Medications and Their Association with Pain Medication Use in Medicare Beneficiaries with Alzheimer's Disease/Alzheimer's Disease-Related Dementias and Chronic Pain

INTRODUCTION

Chronic pain is prevalent among older adults with Alzheimer's disease (AD) and Alzheimer's disease-related dementias (ADRD). Memantine and acetylcholinesterase inhibitors (ACHEI; donepezil, rivastigmine, and galantamine) are approved for the treatment of dementia symptoms and may also have analgesic properties. However, findings on the clinical utility of these dementia medications for chronic pain treatment are mixed, and little is known about differences in the use of pain medication according to whether an older adult with AD/ADRD is using dementia medications.

METHODS

We selected a 20% national sample of Medicare enrollees with a diagnosis of AD/ADRD and chronic pain in 2020. We calculated the odds of having any pain management prescription (opioids, serotonin and norepinephrine reuptake, gapapentinoids, or non-steroidal anti-inflammatory drugs), having an opioid prescription, and having a long-term (≥ 90 days) opioid prescription, by dementia medication (none, memantine, ACHEI, or memantine and ACHEI).

RESULTS

Among 103,564 patients, 5.5% received a memantine prescription, 14.4% received an ACHEI prescription, and 8.6% received a prescription for both. Over 70% of all patients had a pain management prescription. The percentage of patients who had an opioid prescription ranged from 54.5% for those without a dementia medication prescription to 44.0% for those with a prescription for both memantine and ACHEI. Similarly, the percentage of patients who had a long-term opioid prescription was highest for those without a dementia medication prescription (12.2%) and lowest for those with a prescription for both memantine and ACHEI (8.8%). Having a prescription for memantine only was associated with lower odds of any pain management prescription (odds ratio [OR]: 0.94; 95% confidence interval [CI]: 0.88-1.00; p < 0.05). Having a prescription for either memantine (OR: 0.79; 95% CI 0.75-0.84), ACHEI (OR: 0.85; 95% CI 0.82-0.89), or both (OR: 0.75; 95% CI 0.72-0.79) was associated with lower odds of having an opioid prescription (p < 0.05). Lastly, having a prescription for either memantine (OR: 0.85; 95% CI 0.77-0.94), ACHEI (OR: 0.92; 95% CI 0.86-0.98), or both (OR: 0.83; 95% CI 0.77-0.90) was associated with lower odds of having a long-term opioid prescription.

DISCUSSION

Older adults with co-occurring AD/ADRD and chronic pain who were on dementia medications had lower odds of being prescribed opioid analgesics. Memantine and ACHEIs should be explored as potential opioid-sparing medications for older adults with AD/ADRD, given their relatively safe profiles. Future studies are needed to examine repurposing dementia medications for pain treatment.

The process of pain assessment in people with dementia living in nursing homes: a scoping review

Background

Pain is a common symptom in people with dementia living in nursing homes, but cognitive impairment, including language and communication difficulties, challenges pain assessment and the ability to self-report pain.

Objectives

This study aimed to identify and summarize patterns, advances, and gaps in research literature describing pain assessment in people with dementia living in nursing homes.

Design

We conducted a scoping review following Arksey and O'Malley's methodological framework.

Methods

Systematic searches were conducted in CINAHL, Embase, MEDLINE, and PsycINFO. We included studies describing pain expressions in people with dementia and/or healthcare personnel assessment of pain in people with dementia, in a nursing home context. Charted data included demographics, methodological descriptions, ethical and quality assessment and relevant findings. Relevant findings were summarized using thematic analysis, and an overview of patterns, advances, and gaps in the research literature is presented.

Results

Thirty-nine studies were included. The results describe three patterns: (1) pain awareness; (2) suspected pain and (3) pain mapping. Collectively, these patterns constitute a process of pain assessment, integrating pain expressions of people with dementia. Important perspectives on self-reporting are touched upon in several of the included studies, though direct descriptions of attempts to capture the residents' own experience of pain are sparse.

Conclusion

This scoping review provides a comprehensive description of pain assessment in people with dementia living in nursing homes as a process in three steps. We identified several knowledge gaps in the understanding of this process and provide concrete recommendations for further research. The results underpin the importance of pain assessment approaches that incorporate the flexibility to meet residents' varying and potentially fluctuating ways of communicating pain.

Trial registration

This scoping review is registered in the Open Science Framework (https://osf.io/8kaf5/).

Real-time evaluation of an automated computer vision system to monitor pain behavior in older adults

Regular use of standardized observational tools to assess nonverbal pain behaviors results in improved pain care for older adults with severe dementia. While frequent monitoring of pain behaviors in long-term care (LTC) is constrained by resource limitations, computer vision technology has the potential to mitigate these challenges. A computerized algorithm designed to assess pain behavior in older adults with and without dementia was recently developed and validated using video recordings. This study was the first live, real-time evaluation of the algorithm incorporated in an automated system with community-dwelling older adults in a laboratory. Three safely-administered thermal pain tasks were completed while the system automatically processed facial activity. Receiver Operating Characteristic curves were used to determine the sensitivity and specificity of the system in identifying facial pain expressions using gold standard manual coding. The relationship between scoring methods was analyzed and gender differences were explored. Results supported the potential viability of the system for use with older adults. System performance improved when more intense facial pain expressiveness was considered. While average pain scores remained homogenous between genders, system performance was better for women. Findings will be used to further refine the system prior to future field testing in LTC.

The use of photovoice to explore the physical disability experience in older adults with mild cognitive impairment/early dementia

Although co-occurring cognitive impairment and physical disability in older adults is common, there is little understanding of how this group perceives their ability to do their daily activities. This study used photovoice to explore how older adults with MCI/early dementia and physical disability without and with care partners (dyads) perceive challenges with their daily activities. Photovoice is a visual research methodology to capture participants' insight on aspects of their daily lives. No known studies have taken this approach to explore the experiences of older adults with MCI/early dementia and co-occurring physical disability. We used a cross-sectional, exploratory research design to understand participants' (n = 12) experiences in their home environment. Photos and participant thoughts on the photos were categorized based on the Blackfoot Breath of Life Theory and the Hierarchy Model of Needs in Dementia, an adaptation of Maslow's Model. Notable findings included: awareness of physical/cognitive difficulties by older adults, solutions for ADL difficulty in persons with MCI/early dementia, care partners' difficulty recognizing pain without the presence of severe emotional or physical responses, reducing mood severity, and self-esteem needs met with structured, memory-issue adapted, meaningful activities. Older adults with co-occurring physical disability and MCI/early dementia identified both physiological and psychological needs despite challenges impacting their cognition. Photovoice evoked daily situations of these individuals and revealed the importance of developing individualized intervention elements for older adults with dementia and physical disability.

Protocol for a usability and pilot implementation study of a digital medical device to assess pain in non-verbal people with dementia in Portuguese residential care facilities

Objective

People living with moderate to severe dementia (PLWD) are often unable to self-report pain. This matter is of particular concern given that up to 80% experience chronic pain. Mistreated or untreated pain in PLWD is associated with symptoms such as agitation and aggression, and unnecessary use of antipsychotic agents. Further, it can also engender mental burden in formal caregivers. The PainChek® App, a regulatory cleared class I medical device, enables the assessment and monitoring of pain in people who cannot verbalise it, such as those with moderate to severe dementia. To date there are no data on the real-world use of the PainChek® App in Portugal. To address this gap, we report the protocol of a pilot study, which combines usability evaluation and implementation research.

Methods

Usability evaluation of the PainChek® (Portuguese) App will be guided by the ISO framework, focused on effectiveness, efficiency and user satisfaction. Implementation research will combine qualitative interviews to inform the implementation process, a longitudinal study of formal caregivers' psychological variables, implementation outcomes, plus qualitative interviews to explore the 'hows' and 'whys' of implementation. The NASSS framework will be used as an implementation framework, together with the COM-B model and the Theoretical Domains Framework.

Results

The usability and implementation studies have received ethics approval from the Egas Moniz Ethics Committee, under numbers 1367 and 64/24, respectively.

Conclusion

This study is expected to inform the scale-up of the PainChek® (Portuguese) App in real-world settings and establish a foundation for a larger effectiveness and implementation study.

Are orofacial pain assessment tools for adults who cannot self-report pain suitable for dental practice? A scoping review

INTRODUCTION

This study aims to identify and appraise orofacial pain assessment tools designed to score pain in adults who cannot self-report and rate their suitability for dental practice.

METHODS

A protocolled systematic scoping review, in accordance with Joanna Briggs Institute methods was completed. A development panel (n = 7) reviewed attributes of each tool for suitability for use in dental practice, using predefined criteria.

RESULTS

Nine studies were included. Sample size ranged from n = 22 to n = 348; all participants were 65 years plus and had a cognitive impairment or dementia, excluding controls. Four tools were identified: Facial action coding system (FACS), mobilization-observation-behavior-intensity in dementia pain scale (MOBID I & II) and, orofacial pain scale-non-verbal individuals (OPS-NVI). Tools scored between two and thirteen out of twenty according to modified quality assessment criteria. No tool was deemed suitable for use in dental surgery, with the OPS-NVI scoring most favorably.

CONCLUSIONS

No tools were deemed ideal for use within a dental clinic. Elements of some, particularly the OPS-NVI, may be adaptable for this purpose. Despite the difficulties dental practitioners face trying to assess pain in non-speaking patients, there was no suitable tool identified. Pathways need to be designed to facilitate inclusive orofacial pain assessment for those who cannot self-report pain.

Effects of timely case conferencing between general practitioners and specialist palliative care services on symptom burden in patients with advanced chronic disease: results of the cluster-randomised controlled KOPAL trial

BACKGROUND

Patients with advanced chronic non-malignant conditions often experience significant symptom burden. Therefore, overcoming barriers to interprofessional collaboration between general practitioners (GPs) and specialist palliative home care (SPHC) teams is essential to facilitate the timely integration of palliative care elements. The KOPAL trial aimed to examine the impact of case conferences between GPs and SPHC teams on symptom burden and pain in patients with advanced chronic heart failure, chronic obstructive pulmonary disease, and dementia.

METHODS

The cluster-randomised controlled trial compared a structured palliative care nurse visit followed by an interprofessional case conference to usual care. Data were collected from GPs at baseline and 48 weeks, while standardised patient interviews were conducted at baseline, 6, 12, 24, and 48 weeks.

RESULTS

We analysed 172 patients from 49 German GP practices. Both groups showed marginal improvement in symptom burden; however, no statistically significant between-group difference was found ([Formula: see text]=-0.561, 95% CI: -3.201-2.079, p = .68). Patients with dementia experienced a significant pain reduction ([Formula: see text]=2.187, 95% CI: 0.563-3.812, p = .009). Conversely, the intervention did not have a significant effect on pain severity ([Formula: see text]=-0.711, 95% CI: -1.430 - 0.008, p=.053) or pain interference ([Formula: see text]=-0.036, 95% CI:-0.797 - 0.725, p=.926) in other patient groups.

CONCLUSIONS

The intervention showed promise in the timely introduction of palliative care elements to address pain management in patients with dementia. Further studies are needed to identify and effectively address symptom burden and pain in other patient groups.

Usability Testing of the PACE-App to Support Family Caregivers in Managing Pain for People With Dementia

BACKGROUND AND OBJECTIVES

Pain management is often suboptimal in individuals with dementia, and their family caregivers are tasked with supporting pain management despite limited preparation. The web-based PACE-app (PAin Control Enhancement) was designed to assist caregivers in managing pain for individuals with dementia. This study aimed to evaluate the usability of the PACE-app.

RESEARCH DESIGN AND METHODS

A convergent parallel mixed-methods design was used to evaluate the PACE-app's usability with 16 family caregivers and 6 healthcare professionals. Quantitative data were collected using the Post-Study System Usability Questionnaire (PSSUQ), and qualitative data were gathered through guided-app reviews and semistructured interviews. Quantitative data were analyzed descriptively, and qualitative data were thematically coded.

RESULTS

The PSSUQ results indicated that both family caregivers and healthcare professionals had a highly positive experience with the PACE-app: overall scores (2.01 vs 1.68), system usefulness (1.76 vs 1.68), information quality (1.98 vs 1.80), interface quality (2.30 vs 1.60), and satisfaction (2.00 vs 1.60) were rated on a 1-7 scale (with lower scores indicating better usability). Qualitative findings supported these results, with participants endorsing the PACE-app's usefulness, ease of use, learnability, effective information presentation, aesthetics, clear layout, and overall satisfaction. Participants also provided valuable feedback for improving information quality (enhancing clarity) and interface quality (real-time coaching on pain management).

DISCUSSION AND IMPLICATIONS

The study demonstrated favorable usability and strong satisfaction among family caregivers and healthcare professionals using the PACE-app. Incorporating participants' suggestions will guide enhancements to the app's information and interface, ensuring it better meets users' needs.

Pain Assessment in the Patient Unable to Self- Report: Clinical Practice Recommendations in Support of the ASPMN 2024 Position Statement

Recognizing and managing pain is especially challenging for vulnerable populations who cannot communicate their discomfort. Because there is no valid and reliable objective measure of pain, the American Society for Pain Management Nursing advocates for comprehensive assessment practices articulated in a Hierarchy of Pain Assessment. These practices must gather relevant information to infer the presence of pain and evaluate a patient's response to treatment. Nurses and other healthcare providers must be advocates for those who cannot communicate their pain experience.

Nurses' Beliefs About Pain Assessment in Dementia: A Qualitative Study Informed by the Theory of Planned Behaviour

AIM

To explore registered nurses' beliefs regarding pain assessment in people living with dementia.

DESIGN

A descriptive exploratory qualitative study informed by the Theory of Planned Behaviour.

METHODS

Online semi-structured in-depth interviews were conducted from January to April 2023 with a purposive sample of 15 registered nurses caring for people with dementia. Following transcription, data were analysed using direct content analysis.

FINDINGS

Registered nurses believe pain assessment improves the well-being of people with dementia and informs and evaluates practice. However, there is a possibility of misdiagnosing pain as agitation or behavioural problems, leading to inaccurate pain management. Interpersonal factors, such as registered nurses' knowledge and experience, beliefs and motivation to improve care provision, were the primary facilitators of pain assessment. Physical and behavioural dimensions of the pain of the dementia syndrome were the most reported barriers to pain assessment. Registered nurses reported that multidisciplinary team members expect them to do pain assessments. Most did not experience disapproval when performing pain assessments.

CONCLUSION

Registered nurses hold beliefs about pain assessment benefits, consequences, enablers, barriers, approvals and disapprovals regarding dementia. The findings could inform interventions to enhance pain assessment practices.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Policymakers should provide education opportunities for registered nurses to improve their knowledge, skills and beliefs about pain assessment in dementia. Future research should develop and implement multidisciplinary, multifaceted pain assessment protocols to enhance the accuracy of pain assessment practices.

IMPACT

Pain is underassessed in dementia, and this could stem from registered nurses' beliefs about pain assessment in dementia. The findings could inform interventions to enhance pain assessment beliefs and practices.

REPORTING METHOD

This study adhered to the COREQ criteria.

PATIENT OR PUBLIC CONTRIBUTION

Registered nurses caring for people living with dementia participated as interview respondents.

Antidementia and Psychotropic Drug Use in Older People with Dementia in Australia: A National Data Linkage Study

OBJECTIVES

To estimate the national prevalence of antidementia and psychotropic medication use, and sociodemographic factors associated with their use, in Australians living with dementia.

DESIGN

Retrospective cross-sectional study.

SETTING AND PARTICIPANTS

Nationwide data linkage study using 2021 Census and Pharmaceutical Benefits Scheme (PBS) data. All people aged 65 or older with dementia (self-reported in the Census or dispensed an antidementia drug subsidized by the PBS) were included.

METHODS

Medication use was defined as at least 1 dispensing during the 3-month period following the Census (August-October 2021). Prevalence of antidementia and psychotropic medication use, including antipsychotics, benzodiazepines and Z-drugs, antiepileptics, opioids, and psychostimulants, was calculated. Sociodemographic factors associated with medication use were explored using multivariable logistic regression models.

RESULTS

Of the 177,809 older people living with dementia included, 58.6% were using at least 1 psychotropic medication. Antidepressants were the most commonly used psychotropics (41%), followed by opioids (20%) and antipsychotics (13%). Antidementia medications were used by a quarter of people with dementia (26%). People with dementia living in the highest socioeconomic area were more likely to use antidementia medications [adjusted odds ratio (OR), 1.22; 95% CI, 1.17-1.28] and less likely to use psychotropics (OR, 0.91; 95% CI, 0.88-0.95) compared with people living in the lowest socioeconomic area. Conversely, those living in inner regional areas were more likely to use psychotropics (OR, 1.06; 95% CI, 1.03-1.10) and less likely to use antidementia medications (OR, 0.79; 95% CI, 0.77-0.82) compared with people living in metropolitan areas.

CONCLUSIONS AND IMPLICATIONS

Psychotropics were commonly used in people with dementia in Australia. Disparities in access to health care due to socioeconomic status or remoteness may have influenced the use of antidementia and psychotropic medications. Further strategies to allow more equitable access to resources and medications are needed.

Minimising Harm and Managing Pain: Deprescribing Opioids in Older Adults

Approximately one in three older adults (aged 65 years and over) experience pain, negatively impacting their quality of life. Opioid analgesics are commonly prescribed to manage pain; however, balancing the benefits and harms of these high-risk analgesics can be challenging for both healthcare professionals and patients. This is particularly true for older adults, as factors such as polypharmacy, age-related physiological changes and cognitive decline may impact upon opioid safety and efficacy. Deprescribing is the patient-centred process of reducing or discontinuing a medication that is no longer appropriate, or where the risks of continuation are deemed to outweigh the anticipated benefits. Opioid deprescribing has been proposed as a mechanism to reduce individual and societal opioid-related harm; however, to date, research has predominantly focused on the general adult population, rather than older adults. This current opinion aims to summarise the existing opioid deprescribing literature, discussing its applicability for older adults. Drawing on a non-systematic review of the literature, it identifies unique challenges and considerations for this population, highlights international initiatives to enhance opioid deprescribing in clinical practice and proposes future directions to advance the field.

Clinical and Market Analysis of NanoBEO: A Public-Worth, Innovative Therapy for Behavioral and Psychological Symptoms of Dementia (BPSD)-Emerging Evidence and Its Implications for a Health Technology Assessment (HTA) and Decision-Making in National Health Systems

BACKGROUND

According to scientific literature, some 99% of patients affected by Alzheimer's disease (AD) suffer from behavioral and psychological symptoms of dementia (BPSD), also known as neuropsychiatric symptoms (NPSs). In particular, agitation is one of the most difficult disorders to treat. States of agitation represent a very serious problem as they make these subjects dangerous for themselves and others and worsen as the disease advances. To date, there are no specific solutions for treating agitation. The only authorized drug is risperidone (as well as brexpiprazole, approved by the FDA on 11 May 2023), which can be used for no longer than 6-12 weeks because it increases the risk of death-owing to cardiocerebrovascular accidents-by 1.6-1.7 times.

METHODS

In order to address the latter noteworthy unmet medical need, NanoBEO was produced. The aim of the present work is to generate the health technology assessment (HTA) of this nanotechnological device. The latter consists of a controlled release system, based on solid lipid nanoparticles loaded with bergamot essential oil (BEO).

RESULTS

The results of the present research assessed the current evidence in the field of non-pharmacological treatments for this condition, including relevant primary preclinical and clinical data studies supporting the use of this device and the production of the operative plan for its launch on the market. The findings offer recommendations for decision-making on its implementation in dementia.

CONCLUSIONS

NanoBEO represents a public-worth innovation in this neglected area, marking a significant advancement in the history of dementia, moving from academic research to product development.

An alternative theoretical approach to develop a new conception about pain in people with dementia

The theoretical approach presented in this paper describes a novel experimental-theoretical methodology to conceptualise pain in people with dementia. Existing procedures for assessment of pain rely on subjective self-report using pain questionnaires and rating scales that have proven to be highly problematic where a person has dementia. Consequently, pain in people with dementia can be undetected and/or undertreated. To address that, we have developed an alternative experimental approach that builds on theoretical and methodological precedents from the arts, humanities and social sciences, for instance, visual thinking strategies, creative thinking or two-step flow of communication. Based on this approach, we designed an experimental workshop setting to ingrate these methodologies to explore pain and its expression in people with dementia. This had led to a new definition of pain as an interruption of the socially mediated process of bodily meaning-making. Furthermore, our experimental methodology could equally well be applied as a training method, where professional staff can intervene into existing implicit meanings and understandings of medical issues. These results emphasise that the future of pain research needs to consider the relational aspects of pain more seriously.

Pain in non-communicative older adults beyond dementia: a narrative review

Aging is associated with an increased risk of developing pain, especially in the presence of concurrent chronic clinical conditions. Similarly, multimorbidity can affect the perception and ability of older adults to appropriately respond to and communicate pain, and there is a clinical heterogeneity in the processing of painful sensations in different neurological conditions. The present narrative review is aimed at assessing the prevalent diseases associated with poor communication and pain in older adults, together with the available diagnostic instruments for the clinical assessment of pain in such a vulnerable population. Dementia was the most described pathology identified in the current literature associated with poor communication in older adults affected by pain, along with Parkinson's disease and stroke. Notably, a common pattern of pain behaviors in these neurological disorders also emerged, indicating potential similarities in the clinical presentation and appropriate diagnostic workout. At the same time, there are many differences in the way patients express their pain according to their main neurological pathology. In addition to this, although a plethora of observation-based tools for pain in patients with dementia have been developed, there is no gold standard, and the clinical utility of such measurements is still largely unaddressed. Meanwhile, there is substantially no standardized observation-based tool for pain in non-communicative patients with Parkinson's disease, and only a few for stroke. Overall, the present narrative review provides an update on the prevalent diseases beyond dementia associated with a communicative disability and a painful condition in older adults.

Differences in Staff-Resident Care Interactions by Nursing Home Racial Composition: a Preliminary Analysis

Limited research has examined racial differences in the quality of staff-resident care interactions in long-term care settings. The quality of care interactions can significantly affect resident quality of life and psychological well-being among nursing home residents living with dementia. Limited research has assessed racial or facility differences in the quality of care interactions. The purpose of the present study was to determine if there were differences in the quality of care interactions among nursing home residents with dementia between Maryland nursing home facilities with and without Black residents. It was hypothesized that after controlling for age, cognition, comorbidities, and function, the quality of care interactions would be better in facilities with Black residents versus those in which there were only White residents. Baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) intervention study was used and included 276 residents. The results indicated that facilities in Maryland with Black residents had a 0.27 increase (b = 0.27, p < .05) in the quality of care interaction score compared to facilities without Black residents. The findings from this study will be used to inform future interventions to aid in reducing quality of care disparities in nursing home facilities with and without Black nursing home residents. Future work should continue to examine staff, resident, and facility characteristics associated with the quality of care interactions to improve quality of life among all nursing home residents regardless of race or ethnicity.

Clinical and Adverse Outcomes Associated With Concomitant Use of CYP2D6-Metabolized Opioids With Antidepressants in Older Nursing Home Residents : A Target Trial Emulation Study

BACKGROUND

Limited evidence exists on the safety of pharmacokinetic interactions of cytochrome P450 (CYP) 2D6 (CYP2D6)-metabolized opioids with antidepressants among older nursing home (NH) residents.

OBJECTIVE

To investigate the associations of concomitant use of CYP2D6-metabolized opioids and antidepressants with clinical outcomes and opioid-related adverse events (ORAEs).

DESIGN

Retrospective cohort study using a target trial emulation framework.

SETTING

100% Medicare NH sample linked to Minimum Data Set (MDS) from 2010 to 2021.

PARTICIPANTS

Long-term residents aged 65 years and older receiving CYP2D6-metabolized opioids with a disease indication for antidepressant use.

INTERVENTION

Initiating CYP2D6-inhibiting versus CYP2D6-neutral antidepressants that overlapped with use of CYP2D6-metabolized opioids for 1 day or more.

MEASUREMENTS

Clinical outcomes were worsening pain, physical function, and depression from baseline to quarterly MDS assessments and were analyzed using modified Poisson regression models. The ORAE outcomes included counts of pain-related hospitalizations and emergency department (ED) visits, opioid use disorder (OUD), and opioid overdose and were analyzed with negative binomial or Poisson regression models. All models were adjusted for baseline covariates via inverse probability of treatment weighting.

RESULTS

Among 29 435 identified residents, use of CYP2D6-metabolized opioids concomitantly with CYP2D6-inhibiting (vs. CYP2D6-neutral) antidepressants was associated with a higher adjusted rate ratio of worsening pain (1.13 [95% CI, 1.09 to 1.17]) and higher adjusted incidence rate ratios of pain-related hospitalization (1.37 [CI, 1.19 to 1.59]), pain-related ED visit (1.49 [CI, 1.24 to 1.80]), and OUD (1.93 [CI, 1.37 to 2.73]), with no difference in physical function, depression, and opioid overdose.

LIMITATION

Findings are generalizable to NH populations only.

CONCLUSION

Use of CYP2D6-metabolized opioids concomitantly with CYP2D6-inhibiting (vs. CYP2D6-neutral) antidepressants was associated with worsening pain and increased risk for most assessed ORAEs among older NH residents.

Nurses' knowledge and beliefs on pain management practices with hospitalised persons living with dementia: A qualitative descriptive study

AIM

To understand nurses' knowledge, beliefs and experiences affect pain management practices in hospitalised persons living with dementia (PLWD).

DESIGN

Naturalistic inquiry using qualitative descriptive design.

METHODS

Semi-structured interviews were conducted with 12 registered nurses who worked in one acute care hospital in Southern California from October to November 2022. Data were analysed using content analysis to identify themes.

RESULTS

Two themes were developed: improvising pain assessment, which included how pain was documented, and administration hesitancy referring to nurse's concerns about PLWD's confusion. Nurses described the challenges of assessing pain in hospitalised PLWD particularly if they were non-verbal and/or demonstrating responsive behaviours. Nurse's years of experience, dementia stigma, and their unconscious biases affected nurses' pain management practices.

CONCLUSIONS

The study findings highlight the complex challenges of pain management in hospitalised PLWD that are exacerbated by nurses' knowledge deficits, negative stereotypical beliefs, dementia stigma and unconscious biases towards older people that contributes to undermanaged pain in hospitalised PLWD.

IMPLICATIONS

A comprehensive strategy using an implementation framework is needed to address nurse's knowledge gaps, unconscious bias, dementia stigma and techniques that enhance communication skills is suggested. Building a foundation in these areas would improve pain management in hospitalised PLWD.

IMPACT

Improving pain management in hospitalised PLWD would improve the quality of life, decrease hospital length of stay, prevent readmissions, and improve nurse satisfaction.

REPORTING METHOD

The study adhered to the Consolidated Criteria for Reporting Qualitative Research (COREQ).

PATIENT CONTRIBUTIONS

Improving pain management in hospitalised PLWD would prevent long term confusion, episodes of delirium and improve quality of life as they recover from their acute illness for which they required hospital care.

Pain prevalence and pain relief in end-of-life care - a national registry study

BACKGROUND

Despite pain control being a top priority in end-of-life care, pain continues to be a troublesome symptom and comprehensive data on pain prevalence and pain relief in patients with different diagnoses are scarce.

METHODS

The Swedish Register of Palliative Care (SRPC) was used to retrieve data from 2011 to 2022 about pain during the last week of life. Data were collected regarding occurrence of pain, whether pain was relieved and occurrence of severe pain, to examine if pain differed between patients with cancer, heart failure, chronic obstructive pulmonary disease (COPD) and dementia. Binary logistic regression models adjusted for sex and age were used.

RESULTS

A total of 315 000 patients were included in the study. Pain during the last week of life was more commonly seen in cancer (81%) than in dementia (69%), heart failure (68%) or COPD (57%), also when controlled for age and sex, p < 0.001. Severe forms of pain were registered in 35% in patients with cancer, and in 17-21% in non-cancer patients. Complete pain relief (regardless of pain intensity) was achieved in 73-87% of those who experienced pain, depending on diagnosis. The proportion of patients with complete or partial pain relief was 99.8% for the whole group.

CONCLUSIONS

The occurrence of pain, including severe pain, was less common in patients with heart failure, COPD or dementia, compared to patients with cancer. Compared with cancer, pain was more often fully relieved for patients with dementia, but less often in heart failure and COPD. As severe pain was seen in about a third of the cancer patients, the study still underlines the need for better pain management in the imminently dying.

TRIAL REGISTRATION

No trial registration was made as all patients were deceased and all data were retrieved from The Swedish Register of Palliative Care database.

Adapting an Intervention to Address Barriers to Pain Management in Hospice: Formative Research to Inform EMPOWER-D for Dementia Caregivers

Background

Nearly half of more than 1.7 million older Americans who receive hospice care each year have a primary or comorbid diagnosis of dementia. Pain is often undertreated in this patient population owing to myriad factors, including unmet informational needs among family caregivers.

Objective

We sought to inform the adaptation of a pain education intervention for hospice family caregivers to the context of dementia by eliciting feedback on the educational content covered in adapted intervention materials.

Design

We conducted a multimethod, formative research study to inform the adaptation of an existing, evidence-based intervention.

Setting/Subjects

The study included a purposively recruited sample (n = 33) of hospice professionals (n = 18) and family caregivers (n = 15) from across the United States.

Measurements

Participants quantitatively rated the importance of each of the eight pain concerns presented in the adapted intervention materials (1 = not important to 3 = very important) and provided qualitative feedback via Zoom interview on the acceptability, clinical accuracy, and potential benefits of the adapted content. We analyzed quantitative data via descriptive statistics and qualitative data via content analysis.

Results

Participants rated the adapted educational content as highly important (rangemean = 2.56-3.00), particularly regarding concerns about caregivers' pain assessment, communicating with the hospice team about pain, and addressing misinformation regarding pain medication outcomes. Participants also provided suggestions to strengthen specific educational messages to improve comprehension and uptake.

Conclusions

Findings support the continued development and testing of the adapted intervention.

Unraveling the Tapestry of Pain: A Comprehensive Review of Ethnic Variations, Cultural Influences, and Physiological Mechanisms in Pain Management and Perception

The medical management of pain is a nuanced challenge influenced by sociocultural, demographic, and ethical factors. This review explores the intricate interplay of these dimensions in shaping pain perception and treatment outcomes. Sociocultural elements, encompassing cultural beliefs, language, societal norms, and healing practices, significantly impact individuals' pain experiences across societies. Gender expectations further shape these experiences, influencing reporting and responses. Patient implications highlight age-related and socioeconomic disparities in pain experiences, particularly among the elderly, with challenges in managing chronic pain and socioeconomic factors affecting access to care. Healthcare provider attitudes and biases contribute to disparities in pain management across racial and ethnic groups. Ethical considerations, especially in opioid use, raise concerns about subjective judgments and potential misuse. The evolving landscape of placebo trials adds complexity, emphasizing the importance of understanding psychological and cultural factors. In conclusion, evidence-based guidelines, multidisciplinary approaches, and tailored interventions are crucial for effective pain management. By acknowledging diverse influences on pain experiences, clinicians can provide personalized care, dismantle systemic barriers, and contribute to closing knowledge gaps, impacting individual and public health, well-being, and overall quality of life.

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.

A Scoping Review on Nurse's Pain Management of Older Patients with Dementia in a Hospital Environment

OBJECTIVES

Hospitalized persons living with dementia often experience unrelieved pain. Unmanaged pain during hospitalization has a significant negative effect on quality of life for persons living with dementia. Despite the central role of nurses in pain management, little is known about how nurses manage pain in this patient population in the hospital environment.

DESIGN

A scoping review explored the nurses' pain management practices when caring for persons living with dementia in a hospital setting.

DATA SOURCES AND REVIEW/ANALYSIS METHODS

After an extensive search for all available evidence on how nurses manage pain in hospitalized persons living with dementia, data were extracted on pain management methods that included assessment, intervention, effectiveness of pain management, and the barriers nurses encountered when managing pain. A descriptive content analysis was used to extract data from qualitative studies.

RESULTS

Six articles published between 2016 and 2021 met the inclusion criteria; four utilized qualitative methods, and the others used mixed-methods and quantitative study designs. A narrative description of the findings was summarized after data were categorized into pain management data elements and barriers nurses encountered when managing pain. Barriers were grouped into the subcategories of communication challenges (nurse to patient), information sharing (nurse to nurse), lack of knowledge, time constraints, and nursing stressors.

CONCLUSION

We identified six articles that met our inclusion criteria, highlighting a noticeable gap in the literature. Managing pain in this population is complex and lacks organizational support. Review findings indicate that pain management methods lack consistency and standardization, making it difficult to assess their effectiveness. Nurses also described knowledge deficits resulting in practice gaps that, when combined with barriers and challenges, result in underrecognized and undermanaged pain.

Burden of Chronic and Heavy Opioid Use Among Elderly Community Dwellers in the U.S

Introduction

Opioid overprescribing may fuel the opioid epidemic and increase the risk of complications of opioid misuse. This study examined trends and determinants of chronic and heavy opioid use among elderly community dwellers in the U.S.

Methods

Medicare Current Beneficiary Surveys data from 2006 to 2019 were used. Common opioid medications were identified in the prescription medication files (n=47,264). Patients with Chronic users were defined as those receiving 6 or more opioid prescriptions within a year or on medication for 3 or more months, and heavy users were those having an average daily dose of 90 or more morphine milligram equivalents or 3,780 morphine milligram equivalents or more per continuous treatment episode.

Results

One in 6 elderly community dwellers ever used opioids during the study period. Chronic users were more likely to be women than men (68.9% vs 31.1%, p<0.001). Of all survey participants, 4.3% were chronic users, and 2.8% were heavy users. Among ever users, 27.7% were chronic users, and 18.1% were heavy users. The rate of opioid use rose from 12.1% in 2006, peaked at 22.8% in 2013, and decreased to 11.7% in 2019. Chronic use was 5.1%, 10.7%, and 7.6%, respectively. Heavy use was 5.5%, 10.7%, and 7.6%, respectively. However, for chronic and heavy users, there was no significant difference in the median opioid dosage and opioid duration between males and females.

Conclusions

Among elderly Medicare beneficiaries, opioid prescriptions have been decreasing since 2013. However, a substantial number of elderly people were chronic and heavy users, calling for better opioid management among them.

Pilot testing implementation of the pain management clinical practice guideline in nursing homes

Pain is a common symptom for older adults living with dementia in nursing homes. Unfortunately, there are many challenges to pain assessment, diagnosis and management for these individuals. The purpose of this study was to pilot test the implementation of the newly published Pain Management Clinical Practice Guideline from AMDA: The Society of Post Acute and Long-Term Care using our theoretically based Pain-CPG-EIT approach. Implementation was provided by a research nurse facilitator and included four components: Component I: Establishing and working with a stakeholder team monthly; Component II: Education of the staff; Component III: Mentoring and motivating the staff; and Component IV: Ongoing monitoring of pain assessment, diagnosis and management for residents. Findings provide some preliminary support for the feasibility and effectiveness of our implementation approach.

Short- and long-term safety of discontinuing chronic opioid therapy among older adults with Alzheimer's disease and related dementia

BACKGROUND

Limited evidence exists on the short- and long-term safety of discontinuing versus continuing chronic opioid therapy (COT) among patients with Alzheimer's disease and related dementias (ADRD).

METHODS

This cohort study was conducted among 162,677 older residents with ADRD and receipt of COT using a 100% Medicare nursing home sample. Discontinuation of COT was defined as no opioid refills for ≥90 days. Primary outcomes were rates of pain-related hospitalisation, pain-related emergency department visit, injury, opioid use disorder (OUD) and opioid overdose (OD) measured by diagnosis codes at quarterly intervals during 1- and 2-year follow-ups. Poisson regression models were fit using generalised estimating equations with inverse probability of treatment weights to model quarterly outcome rates between residents who discontinued versus continued COT.

RESULTS

The study sample consisted of 218,040 resident episodes with COT; of these episodes, 180,916 residents (83%) continued COT, whereas 37,124 residents (17%) subsequently discontinued COT. Discontinuing (vs. continuing) COT was associated with higher rates of all outcomes in the first quarter, but these associations attenuated over time. The adjusted rates of injury, OUD and OD were 0, 69 and 60% lower at the 1-year follow-up and 11, 81 and 79% lower at the 2-year follow-up, respectively, for residents who discontinued versus continued COT, with no difference in the adjusted rates of pain-related hospitalisations or emergency department visits.

CONCLUSIONS

The rates of adverse outcomes were higher in the first quarter but lower or non-differential at 1-year and 2-year follow-ups between COT discontinuers versus continuers among older residents with ADRD.

Prevalence and trend of central nervous system-active medication polypharmacy among US commercially insured adults with vs without early-onset dementia: a multi-year cross-sectional study

BACKGROUND

Limited data exist on the prevalence and trend of central nervous system (CNS)-active medication polypharmacy among adults with early-onset dementia (EOD) and whether these estimates differ for adults without EOD but with chronic pain, depression, or epilepsy, conditions managed by CNS-active medications.

METHODS

A multi-year, cross-sectional study using 2012-2021 MarketScan Commercial Claims data was conducted among adults aged 30 to 64 years with EOD and those without EOD but having a diagnosis of chronic pain, depression, or epilepsy as comparison groups. For each disease cohort, the primary outcome was CNS-active medication polypharmacy defined as concurrent use of ≥ 3 CNS-active medications on the US Beers Criteria list that overlapped for > 30 consecutive days during 12 months following a randomly selected medical encounter with the disease diagnosis. A separate multivariate modified Poisson regression model was used to estimate time trends in CNS polypharmacy in each disease cohort. Differences in trend estimates between EOD and non-EOD disease cohorts were examined by an interaction between EOD status and yearly time.

RESULTS

From 2013 to 2020, the annual crude prevalence of CNS polypharmacy was higher among adults with EOD (21.2%-25.0%) than adults with chronic pain (5.1%-5.9%), depression (14.8%-21.7%), or epilepsy (20.0%-22.3%). The adjusted annual prevalence of CNS polypharmacy among patients with EOD did not significantly change between 2013 and 2020 (adjusted prevalence rate ratio [aPRR], 0.94; 95% CI, 0.88-1.01), whereas a significant decreasing trend was observed among non-EOD cohorts with chronic pain (aPRR, 0.66; 95% CI, 0.63-0.69), depression (aPRR, 0.81; 95% CI, 0.77-0.85), and epilepsy (aPRR, 0.86; 95% CI, 0.83-0.89). The interaction analysis indicated that patients with epilepsy and depression (vs with EOD) had a decreasing probability of CNS-active medication polypharmacy over time (aPRR, 0.98 [95% CI, 0.98-0.99]; P < .001 for interaction for both conditions).

CONCLUSIONS

The prevalence of CNS polypharmacy among US commercially insured adults with EOD (vs without) was higher and remained unchanged from 2013 to 2021. Medication reviews of adults with EOD and CNS polypharmacy are needed to ensure that benefits outweigh risks associated with combined use of these treatments.

Pain intensity, physical function, and depressive symptoms associated with discontinuing long-term opioid therapy in older adults with Alzheimer's disease and related dementias

INTRODUCTION

Limited evidence exists on the associations of discontinuing versus continuing long-term opioid therapy (LTOT) with pain intensity, physical function, and depression among patients with Alzheimer's disease and related dementias (ADRD).

METHODS

A cohort study among 138,059 older residents with mild-to-moderate ADRD and receipt of LTOT was conducted using a 100% Medicare nursing home sample. Discontinuation of LTOT was defined as no opioid refills for ≥ 60 days. Outcomes were worsening pain, physical function, and depression from baseline to quarterly assessments during 1- and 2-year follow-ups.

RESULTS

The adjusted odds of worsening pain and depressive symptoms were 29% and 5% lower at the 1-year follow-up and 35% and 9% lower at the 2-year follow-up for residents who discontinued versus continued LTOT, with no difference in physical function.

DISCUSSION

Discontinuing LTOT was associated with lower short- and long-term worsening pain and depressive symptoms than continuing LTOT among older residents with ADRD.

HIGHLIGHTS

Discontinuing long-term opioid therapy (LTOT) was associated with lower short- and long-term worsening pain. Discontinuing LTOT was related to lower short- and long-term worsening depression. Discontinuing LTOT was not associated with short- and long-term physical function.

Sex and Sleep Disruption as Contributing Factors in Alzheimer's Disease

Alzheimer's disease (AD) affects more women than men, with women throughout the menopausal transition potentially being the most under researched and at-risk group. Sleep disruptions, which are an established risk factor for AD, increase in prevalence with normal aging and are exacerbated in women during menopause. Sex differences showing more disrupted sleep patterns and increased AD pathology in women and female animal models have been established in literature, with much emphasis placed on loss of circulating gonadal hormones with age. Interestingly, increases in gonadotropins such as follicle stimulating hormone are emerging to be a major contributor to AD pathogenesis and may also play a role in sleep disruption, perhaps in combination with other lesser studied hormones. Several sleep influencing regions of the brain appear to be affected early in AD progression and some may exhibit sexual dimorphisms that may contribute to increased sleep disruptions in women with age. Additionally, some of the most common sleep disorders, as well as multiple health conditions that impair sleep quality, are more prevalent and more severe in women. These conditions are often comorbid with AD and have bi-directional relationships that contribute synergistically to cognitive decline and neuropathology. The association during aging of increased sleep disruption and sleep disorders, dramatic hormonal changes during and after menopause, and increased AD pathology may be interacting and contributing factors that lead to the increased number of women living with AD.

Pain Management for Older Adults Across the Cognitive Trajectory

Purpose of review

This review investigated current research on the relationship between chronic pain and cognitive performance, subjective cognitive decline, and dementia. In addition, we reviewed current research on pain management in older adults across the cognitive trajectory.

Recent findings

Chronic pain remains a common problem in older adults. A new, international classification system highlights the complexity of chronic pain syndromes. Research supports relationships between chronic pain and changes in cognitive performance in generally healthy adults. Evidence also supports associations between pain and subjective cognitive decline, which is considered a possible precursor to dementia. The impact of dementia on pain expression is also reviewed. To manage pain in older adults, we present a multimodal pain management hierarchy that includes pharmacological and non-pharmacological treatments. To avoid the risks and side effects of analgesics, non-pharmacological treatment is recommended as the first line therapy for chronic pain. Medical cannabis and music therapy are two non-pharmacological treatments that have been the focus of substantial recent research; evidence supports their effectiveness in reducing pain and both strategies warrant further investigation.

Summary

Chronic pain is associated with different levels of cognitive decline across the cognitive trajectory. Medical cannabis and music therapy are the two emerging non-pharmacological treatment methods. Clinical studies with rigorous research design are needed to further investigate the effects of these two strategies on pain relief in older adults.

Analgesic stewardship in Australian residential aged care facilities: Retrospective audit of a collaborative approach to optimising opioid use

OBJECTIVE

To evaluate retrospectively an analgesic stewardship role of a non-dispensing pharmacist as part of a general practice team providing primary care services to residential aged care facilities (RACF).

METHODS

Our general practice implemented an analgesic stewardship program to optimise and monitor opioid usage for our patients located across 12 RACF in Canberra from March 2019 to September 2020. The primary objective was the development of a multidisciplinary chronic pain care plan to document treatment and monitoring strategies for optimising pain control. The pharmacist reviewed and documented existing pain management strategies in a care plan for each patient and discussed recommendations for optimisation with the general practitioner. The general practitioner implemented accepted recommendations and distributed finalised care plans to the RACF. A retrospective audit of care plans was undertaken to assess the outcomes: mean daily oral morphine equivalence to monitor opioid usage, and pain scores to monitor for any potential harm associated with analgesic stewardship.

RESULTS

One hundred and sixty-seven residents received an initial care plan. Residents were scheduled for a follow-up care plan after 6 months, which was achieved for 100 residents (60%). Scope for optimising opioid therapy was identified for 47 residents (28%) at baseline and 23 residents (23%) at follow-up. Mean opioid usage and pain scores were reduced at follow-up; 19.4 mg (SD 40.8) versus 13.4 mg (SD 22.8), and 4.2 (SD 2.3) versus 3.9 (SD 2.0), respectively.

CONCLUSIONS

A systematic, multidisciplinary analgesic stewardship approach may optimise pain management plans and reduce opioid usage in RACF residents.

Implementing PainChek and PARO to Support Pain Assessment and Management in Residents with Dementia: A Qualitative Study

BACKGROUND

Pain is a common problem but often undiagnosed and untreated in people with dementia.

AIMS

This study explored the experiences of residents with dementia, family, andformal carers with (1) pain assessment and management for residents with dementia; (2) the use of the PainChek app for pain assessment, and (3) the use of a social robot PARO for pain management in residents with dementia.

DESIGN

A qualitative study.

SETTINGS/PARTICIPANTS

Interviews were conducted with 13 residents withdementia, three family members, and 18 formal carers from a residential aged carefacility.

METHOD

Residents with dementia interacted with PARO for 15 mins, five days perweek for three weeks. The PainChek app assessed pain levels before and after eachsession. After three-week intervention, individual interviews were conducted withresidents, family, and formal carers who experienced or observed the use of PainChekapp and PARO for residents. Interviews were audio-recorded, transcribed, andanalyzed using thematic analysis.

RESULTS

Four themes were identified regarding pain in residents with dementia: (1) the impact, challenges and strategies of pain assessment and management; (2) benefits and barriers of using PainChek app to assess pain; (3) benefits of interacting with PARO to manage pain and behavioral symptoms; and (4) implementing PainChek app and PARO to support pain assessment and management in dementia care.

CONCLUSIONS

Technology, such as PainChek and PARO, is promising to improve painassessment and reduce pain for people with dementia. Barriers to using technologyinclude limited staff training and the implementation of person-centered care.

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.

Nursing assistants' use of best practices and pain in older adults living in nursing homes

BACKGROUND

Inadequate pain management persists in nursing homes. Nursing assistants provide the most direct care in nursing homes, and significantly improving the quality of care requires their adoption of best care practices informed by the best available evidence. We assessed the association between nursing assistants' use of best practices and residents' pain levels.

METHODS

We performed a cross-sectional analysis of data collected between September 2019 and February 2020 from a stratified random sample of 87 urban nursing homes in western Canada. We linked administrative data (the Resident Assessment Instrument-Minimum Data Set [RAI-MDS], 2.0) for 10,093 residents and survey data for 3547 nursing assistants (response rate: 74.2%) at the care unit level. Outcome of interest was residents' pain level, measured by the pain scale derived from RAI-MDS, 2.0. The exposure variable was nursing assistants' use of best practices, measured with validated self-report scales and aggregated to the unit level. Two-level random-intercept multinomial logistic regression accounted for the clustering effect of residents within care units. Covariates included resident demographics and clinical characteristics and characteristics of nursing assistants, unit, and nursing home.

RESULTS

Of the residents, 3305 (30.3%) were identified as having pain. On resident care units with higher levels of best practice use among nursing assistants, residents had 32% higher odds of having mild pain (odds ratio, 1.32; 95% confidence interval, 1.01-1.71; p = 0.040), compared with residents on care units with lower levels of best practice use among nursing assistants. The care units did not differ in reported moderate or severe pain among residents.

CONCLUSIONS

We observed that higher unit-level best practice use among nursing assistants was associated with mild resident pain. This association warrants further research to identify key individual and organizational factors that promote effective pain assessment and management.

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.

Caregiving self-efficacy and pain assessment by family caregivers of people living with dementia

Like other older adults, people living with dementia (PLWD) experience pain, and the task of pain assessment often falls to family caregivers. In this study, we surveyed family caregivers of PLWD to determine the frequency with which they use different elements of pain assessment. We also determined correlations of family caregivers' characteristics (caregiving self-efficacy, relationship duration and type, mood, education level, and health literacy) with their use of the elements of pain assessment. Participants reported frequent use of many pain assessment elements. Statistically significant correlations were found between caregiving self-efficacy for obtaining respite and asking others about noticed behavior change (rho=.0.41, p=.007); and for responding to disruptive patient behaviors for multiple pain assessment elements including observing pain behaviors (rho=0.49, p<.001), asking others about noticed behavior change (rho=0.54, p<.001) and rechecking (rho=0.56, p<.001). Continued efforts are needed to describe pain assessments by family caregivers of PLWD.

Pain and Associated Factors in Nursing Home Residents

BACKGROUND

Understanding factors associated with risk of pain allows residents and clinicians to plan care and set priorities, however, factors associated with pain in nursing home residents has not been conclusively studied.

AIM

To evaluate the association between pain and nursing home (NH) resident demographic and clinical characteristics.

DESIGN

Retrospective analysis of Minimum Data Set 3.0 records of nursing home residents residing in 44 Indiana NHs between September 27, 2011 and December 27, 2019 (N = 9,060).

RESULTS

Pain prevalence in this sample of NH residents was 23.7%. Of those with pain, 28.0% experienced moderate to severe/frequent pain and 54.6% experienced persistent pain. Risk factors for moderate to severe/frequent pain include female sex; living in a rural setting; intact, mildly, or moderately impaired cognition; arthritis; contracture; anxiety; and depression. In contrast, stroke and Alzheimer's disease and Alzheimer's-disease related dementias (AD/ADRD) were associated with decreased risk of reporting moderate to severe/frequent pain, likely representing both the under-assessment and under-reporting of pain among cognitively impaired NH residents. Risk factors for persistent pain included age <70, Black race, living in a rural location, intact cognition, contracture, and depression.

CONCLUSIONS

Pain remains a pressing problem for NH residents. In this study, we identified demographic and clinical factors associated with moderate to severe frequent pain and persistent pain. Residents with a diagnosis of AD/ADRD were less likely to report pain, likely representing the difficulty of evaluating pain in these residents. It is important to note that those with cognitive impairment may not experience any less pain, but assessment and reporting difficulties may make them appear to have less pain. Knowledge of factors associated with pain for NH residents has the potential for improving the ability to predict, prevent, and provide better pain care in NH residents.

Nursing Practice Variations in Pain Management in Older Adults With Dementia Admitted to an Acute Geriatrics Unit During the COVID-19 Pandemic

The current retrospective descriptive study evaluated nursing practice variations on pain management in older adults with dementia admitted to an acute geriatrics unit (AGU) before (2018) and during (2021) the coronavirus disease 2019 (COVID-19) pandemic. Data were gathered from electronic health records. Pain intensity was evaluated a median of 1.9 times per day of stay in the pre-COVID-19 sample, whereas in the COVID-19 sample, the median was 0.7 times per day of stay. Median number of analgesic administrations per day of stay and mean percentage of clinical care records that mentioned pain were higher in patients admitted during the pandemic. Variations in nursing care organization in the AGU due to the COVID-19 pandemic had an impact on the patterns of pain management nursing practice in older adults with dementia.

Abnormal Spontaneous Discharges of Primary Sensory Neurons and Pain Behavior in a Rat Model of Vascular Dementia

Patients with vascular dementia experience more pain than healthy elders, potentially due to the presence of central neuropathic pain. However, the mechanisms underlying neuropathic pain in vascular dementia remain poorly understood, and there is currently a lack of effective treatment available. In this study, a rat model of vascular dementia was induced by permanently occluding the common carotid arteries bilaterally (2-VO). The cognitive impairments in the 2-VO rats were evaluated using the Morris Water Maze test, while HE and LBF staining were employed to assess brain tissue lesions in the hippocampal, cerebral cortex, and white matter regions known to be associated with severe memory and learning deficits. Furthermore, pain-related behavioral tests, including mechanical and thermal stimuli assessments, were conducted, and in vivo electrophysiological recordings of primary sensory neurons were performed. Compared to sham-operated and pre-operative rats, rats with vascular dementia exhibited mechanical allodynia and thermal hyperalgesia 30 days after surgery. Furthermore, in vivo electrophysiology revealed a significant increase in the occurrence of spontaneous activity of Aβ- and C-fiber sensory neurons in the rat model of vascular dementia. These results indicate that neuropathic pain behaviors developed in the rat model of vascular dementia, and abnormal spontaneous discharges of primary sensory neurons may play a crucial role in the development of pain after vascular dementia.

Uric acid levels and their association with vascular dementia and Parkinson's disease dementia: a meta-analysis

OBJECTIVES

To explore the association between uric acid (UA) levels and vascular dementia (VaD) and Parkinson's disease dementia (PDD), a meta-analysis was conducted.

METHODS

The relevant studies were identified by searching PubMed, Embase, Web of Science, and Cochrane Collaboration Database up to May 2022. Pooled analysis, sensitivity analysis, and publication bias examination were all conducted. All analyses were performed by using STATA 16.

RESULTS

Twelve studies with a total of 2097 subjects were included. The pooled analysis showed that UA levels were not associated with VaD (WMD =  - 10.99 μmol/L, 95% CI (- 48.05, 26.07), P = 0.561) but were associated with PDD (WMD =  - 25.22 μmol/L, 95% CI (- 43.47, - 6.97), P = 0.007). The statistical stability and reliability were evaluated using sensitivity analysis and publication bias outcomes.

CONCLUSION

UA levels are associated with PDD but not with VaD. This study will help to strengthen our knowledge of the pathophysiologies of VaD and PDD, and promote the development of prevention and treatment strategies.

Assessing Pain in Older Adults: Caregivers play a key role in recognizing and documenting pain at home

This article is part of a series, Supporting Family Caregivers: No Longer Home Alone, published in collaboration with the AARP Public Policy Institute. Results of focus groups, conducted as part of the AARP Public Policy Institute's No Longer Home Alone video project, supported evidence that family caregivers aren't given the information they need to manage the complex care regimens of family members. This series of articles and accompanying videos aims to help nurses provide caregivers with the tools they need to manage their family member's health care at home. This new group of articles provides practical information nurses can share with family caregivers of persons living with pain. To use this series, nurses should read the articles first, so they understand how best to help family caregivers. Then they can refer caregivers to the informational tear sheet-Information for Family Caregivers-and instructional videos, encouraging them to ask questions. For additional information, see Resources for Nurses. Cite this article as: Horgas, A.L., et al. Assessing Pain in Older Adults. Am J Nurs 2022; 122 (12): 42-48.

The Functions and Phenotypes of Microglia in Alzheimer's Disease

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease worldwide, but therapeutic strategies to slow down AD pathology and symptoms have not yet been successful. While attention has been focused on neurodegeneration in AD pathogenesis, recent decades have provided evidence of the importance of microglia, and resident immune cells in the central nervous system. In addition, new technologies, including single-cell RNA sequencing, have revealed heterogeneous cell states of microglia in AD. In this review, we systematically summarize the microglial response to amyloid-β and tau tangles, and the risk factor genes expressed in microglia. Furthermore, we discuss the characteristics of protective microglia that appear during AD pathology and the relationship between AD and microglia-induced inflammation during chronic pain. Understanding the diverse roles of microglia will help identify new therapeutic strategies for AD.

Cultural Influence on Nurses' Pain Observations Related to Dementia: An Integrative Review

BACKGROUND

Nurses play a pivotal role in pain observation in people living with dementia. However, currently, there is little understanding of the influence culture may have on the way nurses observe pain experienced by people living with dementia.

AIM

This review explores the influence of culture on nurses... pain observations experienced by people living with dementia.

SETTINGS

Studies were included regardless of the setting (e.g., acute medical care, long-term care, community).

DESIGN

An integrative review.

PARTICIPANTS/SUBJECTS

PubMed, Medline, Psychological Information Database, Cochrane Library, Scopus, Web of Science, Cumulative Index of Nursing and Allied Health Literature, and ProQuest were included in the search.

METHODS

Electronic databases were searched using synonyms for "dementia," "nurse," "culture," and "pain observation." The review included ten primary research papers following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.

RESULTS

Nurses reported that pain observation in people living with dementia is challenging. Four themes were identified by data synthesis: (1) using behaviors for pain observation; (2) information from carers for pain observation; (3) pain assessment tools for pain observation; and (4) role of knowledge, experience, and intuition in pain observation.

CONCLUSIONS

There is a limited understanding of the role of culture on nurses' pain observations. However, nurses take a multifaceted approach to observing pain using behaviors, information from carers, pain assessment tools, and their knowledge, experience, and intuition.

Antidepressant medications in dementia: evidence and potential mechanisms of treatment-resistance

Depression in dementia is common, disabling and causes significant distress to patients and carers. Despite widespread use of antidepressants for depression in dementia, there is no evidence of therapeutic efficacy, and their use is potentially harmful in this patient group. Depression in dementia has poor outcomes and effective treatments are urgently needed. Understanding why antidepressants are ineffective in depression in dementia could provide insight into their mechanism of action and aid identification of new therapeutic targets. In this review we discuss why depression in dementia may be a distinct entity, current theories of how antidepressants work and how these mechanisms of action may be affected by disease processes in dementia. We also consider why clinicians continue to prescribe antidepressants in dementia, and novel approaches to understand and identify effective treatments for patients living with depression and dementia.

Feasibility, Acceptability, and Efficacy of Home-Based Transcranial Direct Current Stimulation on Pain in Older Adults with Alzheimer's Disease and Related Dementias: A Randomized Sham-Controlled Pilot Clinical Trial

Although transcranial direct current stimulation (tDCS) is emerging as a convenient pain relief modality for several chronic pain conditions, its feasibility, acceptability, and preliminary efficacy on pain in patients with Alzheimer's disease and related dementias (ADRD) have not been investigated. The purpose of this pilot study was to assess the feasibility, acceptability, and preliminary efficacy of 5, 20-min home-based tDCS sessions on chronic pain in older adults with ADRD. We randomly assigned 40 participants to active (n = 20) or sham (n = 20) tDCS. Clinical pain intensity was assessed using a numeric rating scale (NRS) with patients and a proxy measure (MOBID-2) with caregivers. We observed significant reductions of pain intensity for patients in the active tDCS group as reflected by both pain measures (NRS: Cohen's d = 0.69, p-value = 0.02); MOBID-2: Cohen's d = 1.12, p-value = 0.001). Moreover, we found home-based tDCS was feasible and acceptable intervention approach for pain in ADRD. These findings suggest the need for large-scale randomized controlled studies with larger samples and extended versions of tDCS to relieve chronic pain on the long-term for individuals with ADRD.

Pain and aging: A unique challenge in neuroinflammation and behavior

Chronic pain is one of the most common, costly, and potentially debilitating health issues facing older adults, with attributable costs exceeding $600 billion annually. The prevalence of pain in humans increases with advancing age. Yet, the contributions of sex differences, age-related chronic inflammation, and changes in neuroplasticity to the overall experience of pain are less clear, given that opposing processes in aging interact. This review article examines and summarizes pre-clinical research and clinical data on chronic pain among older adults to identify knowledge gaps and provide the base for future research and clinical practice. We provide evidence to suggest that neurodegenerative conditions engender a loss of neural plasticity involved in pain response, whereas low-grade inflammation in aging increases CNS sensitization but decreases PNS sensitivity. Insights from preclinical studies are needed to answer mechanistic questions. However, the selection of appropriate aging models presents a challenge that has resulted in conflicting data regarding pain processing and behavioral outcomes that are difficult to translate to humans.
