Psychometric Evaluation of a Pain Intensity Measure for Persons with Dementia

Perception, behavior and experience of nursing assistants towards pain of older adults with dementia: A qualitative study

Nursing assistants are strategically positioned to detect and interpret behavioral alterations indicative of pain in residents suffering from dementia. Despite this, extant literature is scarce regarding their experiences in administering pain care to this demographic. Utilizing a phenomenological approach, this study engaged 17 nursing assistants selected via purposive sampling for semi-structured interviews. Data analysed by the Colaizzi 7-step method. Four emergent themes were discerned: perception of pain; strategies for coping with pain; emotional and psychological responses to pain-related caregiving; challenges and needs in pain-related caregiving. Nursing assistants play a unique and crucial role in the identification of pain, reporting and providing feedback to healthcare professionals, and implementing non-pharmacological interventions. However, these roles have not been fully utilized. Enhancements in pain management could be facilitated by decreasing staff turnover, augmenting educational and training programs, and incorporating empathy-focused situational training. The provision of mental health services is also recommended to ameliorate caregiving-induced stress.

Association between pain and cognitive and daily functional impairment in older institutional residents: a cross-sectional study

BACKGROUND

Pain is often neglected in disabled older population, especially in Taiwan where the population of institutional residents is rapidly growing. Our study aimed to investigate pain prevalence and associated factors among institutional residents to improve pain assessment and management.

METHODS

This nationwide study recruited 5,746 institutional residents in Taiwan between July 2019 and February 2020. Patient self-report was considered the most valid and reliable indicator of pain. A 5-point verbal rating scale was used to measure pain intensity, with a score ranging from 2 to 5 indicating the presence of pain. Associated factors with pain, including comorbidities, functional dependence, and quality of life, were also assessed.

RESULTS

The mean age of the residents was 77.1 ± 13.4 years, with 63.1% of them aged over 75 years. Overall, 40.3% of the residents reported pain, of whom 51.2% had moderate to severe pain. Pain was more common in residents with comorbidities and significantly impacted emotions and behavior problems, and the mean EQ5D score, which is a measure of health-related quality of life (p < .001). Interestingly, pain was only related to instrumental activities of daily living (IADL) and not activities of daily living (ADL). On the other hand, dementia was significantly negatively associated with pain (p < .001), with an estimated odds of 0.63 times (95% CI: 0.53-0.75) for the presence of pain when compared to residents who did not have dementia.

CONCLUSIONS

Unmanaged pain is common among institutional residents and is associated with comorbidities, IADL, emotional/behavioral problems, and health-related quality of life. Older residents may have lower odds of reporting pain due to difficulty communicating their pain, even through the use of a simple 5-point verbal rating scale. Therefore, more attention and effort should be directed towards improving pain evaluation in this vulnerable population .

Pain in older adults with dementia: Brazilian validation of Pain Intensity Measure for Persons with Dementia (PIMD)

BACKGROUND

Although there are several ways to assess pain in dementia, there is still a need for tools with better items to assess the presence of pain intensity in these individuals.

OBJECTIVE

To validate to Brazilian version of the "Pain Intensity Measure for Persons with Dementia - PIMD-p.

METHODS

Older adults, all demented with impaired verbal communication and exposed to potentially painful situations, were selected from an outpatient clinic and long-term care facility (LTCF). The PIMD-p was applied independently by 2 researchers (E1 and E2) on the same day. Within 14 days, the instrument was reapplied by one of the 2 researchers (E3). The pain intensity reported by participants' caregivers and LTCF nurses were recorded on a verbal numeric pain scale. For the statistical analysis, Cronbach's Alpha, Spearman's Coefficient and intraclass correlation Index were calculated.

RESULTS

A total of 50 older individuals were selected (mean age 86 years), majority with musculoskeletal pain. The PIMD-p demonstrated good internal consistency according to Cronbach's α (0.838), excellent intra and interobserver reproducibility (0.927 and 0.970, respectively; p < 0.001), and convergent validity (strong significant correlations between reported pain intensities and pain indicators on the PIMD-p (except for expressive eyes; corr = 0.106 and p = 0.462). A ROC curve was plotted to determine the best cut-off for the PIMD-P, and a score of 7.5 predicted moderate-to-severe pain, with 77.8% sensitivity and 95.7% specificity (p < 0.001).

CONCLUSION

The PIMD-p showed satisfactory psychometric properties for measuring intensity of pain in demented older adults with impaired verbal communication.

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.

Pain trajectories of nursing home residents

BACKGROUND

Understanding changes in nursing home (NH) resident pain over time would provide a more informed perspective, allowing opportunities to alter the course of illness, plan care, and set priorities. Therefore, the purpose of this analysis was to identify and characterize clinically meaningful, dynamic pain trajectories in NH residents.

METHODS

Retrospective longitudinal analysis of NH resident pain scores with a length of stay >100 days (N = 4864). Group-based trajectory modeling was applied to Minimum Data Set 3.0 assessments to identify pain trajectories. Trajectories were then characterized using unadjusted and adjusted cross-sectional associations between residents' demographic and clinical characteristics and their pain trajectory.

RESULTS

We identified four distinct trajectories: (1) consistent pain absence (48.9%), (2) decreasing-increasing pain presence (21.8%), (3) increasing-decreasing pain presence (15.3%), and (4) persistent pain presence (14.0%). Demographics of younger age and living in a rural area were associated with the persistent pain presence trajectory. Clinical variables of obesity and intact cognition were associated with being in the persistent pain presence trajectory. A smaller proportion of residents with moderately or severely impaired cognition were in any of the trajectory groups with pain.

CONCLUSIONS

We identified and characterized four pain trajectories among NH residents, including persistent pain presence which was associated with demographic characteristics (younger, female, rural) and clinical factors (obese, fracture, contracture). Moreover, residents with a diagnosis of Alzheimer's disease or dementia were less likely to be in any of the three trajectories with pain, likely representing the difficulty in evaluating pain in these residents. It is important that NH staff understand, recognize, and respond to the factors associated with the identified pain trajectories to improve mitigation of potentially persistent pain (e.g., hip fracture, contracture) or improve proxy pain assessment skills for residents at risk for under reporting of pain (e.g., Alzheimer's Disease).

CE: Assessing Movement-Evoked Pain

ABSTRACT

One of the most common and nuanced tasks that nurses perform is pain assessment, particularly in acute postoperative settings where frequent reassessments are needed. Most assessments are limited to obtaining a pain intensity score with little attention paid to the conditions necessitating the assessment or the factors contributing to the pain. Pain is frequently assessed during rest, but seldom during periods of movement or activity, which is a crucial omission given that acute postoperative movement-evoked pain (MEP) is intense and a common barrier to healing and restoration of function. In addition to physical limitations, MEP can impede cognitive, emotional, and social functioning in ways that can contribute to chronic pain, mood disorders, and disability. Professional and regulatory standards are moving away from a focus on pain intensity to an emphasis on its context, impact on function, and associated distress. Thus, there are many driving forces compelling nurses to integrate MEP assessments into practice to expedite the restoration of biopsychosocial functioning in postoperative patients. The authors discuss the clinical significance of a MEP assessment as well as protocols and tools for completing such assessments.

Are Chronic Pain Patients with Dementia Being Undermedicated?

In dementia, neuropathological changes alter the perception and expression of pain. For clinicians and family members, this knowledge gap leads to difficulties in recognizing and assessing chronic pain, which may consequently result in persons with dementia receiving lower levels of pain medication compared to those without cognitive impairment. Although this situation seems to have improved in recent years, considerable geographical variation persists. Over the last decade, opioid use has received global attention as a result of overuse and the risk of addiction, while the literature on older persons with dementia actually suggests undertreatment. This review stresses the importance of reliable assessment and the regular evaluation and monitoring of symptoms in persons with dementia. Based on current evidence, we concluded that chronic pain is still undertreated in dementia.

A Paradigm Shift for Movement-based Pain Assessment in Older Adults: Practice, Policy and Regulatory Drivers

BACKGROUND

The profession of nursing has been on the front line of pain assessment and management in older adults for several decades. Self-report has traditionally been the most reliable pain assessment method, and it remains a priority best practice in identifying the presence and intensity of pain. Although advances in technology, biomarkers, and facial cue recognition now complement self-report, it is still important to maximize self-report of pain and to gather understanding of the total pain experience directly from patients. Practices in pain assessment in older adults have evolved over the past 25 years, and current research and quality improvement studies seek not only to detect the presence of pain, but also to determine the best protocol for assessment and most important pain characteristics to assess. Increasing data are now supporting two emerging practices: (1) consistently assessing the impact of pain on function, and (2) measuring pain during movement-based activities rather than at rest.

OBJECTIVE

The purpose of this article is thus to discuss the shifting paradigm for movement-based pain assessment in older adults, as well as the practice, policy, and regulatory drivers that support this practice change.

Pain assessment for cognitively impaired older adults: Do items of available observer tools reflect pain-specific responses?

BACKGROUND

A number of observational tools are available to assess pain in cognitively impaired older adults, however, none of them can yet be regarded as a "gold standard". An international research initiative has created a meta-tool compiling the facial, vocalization and body movement items of the majority of available tools. Objective of this study was to investigate the pain specificity and the validity of these items.

METHOD

N = 34 older adults with or without cognitive impairment were videotaped in three different conditions (one reference, two painful conditions) in their nursing homes. They were further asked to self-report their pain in each condition. The occurrence of non-verbal behaviours was coded as present or absent using the items of the meta-tool.

RESULTS

The majority of non-verbal behaviours was not pain sensitive as they occurred less than three times across participants and conditions. Of the remaining items, two facial items ("pained expression" and "raising upper lip"), one vocalization item ("using pain-related words") and one body movement item ("guarding") were found to be pain specific and valid. One additional item, the vocalization item "gasping", was pain specific, but not associated with pain self-report, and three additional items, the facial items "frowning" and "narrowing eyes" and the vocalization item "mumbling" were correlated with pain self-report but did not help to separate pain from non-pain conditions.

CONCLUSIONS

Systematic evaluation of items of existing observational pain assessment tools under naturalistic conditions seems a promising approach in the process of further investigating and improving tools.

SIGNIFICANCE

Only few items stemming from observational pain assessment tools were found to be pain sensitive and specific as well as valid in this study. The investigation of existing tools not only on tool but additionally on item-level can provide helpful insights and thereby can help to improve the original tools and establish a gold standard for nonverbal pain assessment in older adults with cognitive impairments.

Pain Patterns and Treatment Among Nursing Home Residents With Moderate-Severe Cognitive Impairment

OBJECTIVES

To examine the frequency and severity of pain and use of pain therapies among long-term care residents with moderate to severe dementia and to explore the factors associated with increased pain severity.

DESIGN

Prospective individual data were collected over 1 to 3 days for each participant.

SETTING

Sixteen long-term care facilities in Alabama, Georgia, Pennsylvania, and New Jersey.

PARTICIPANTS

Residents with moderate to severe cognitive impairment residing in a long-term care facility for at least 7 days were enrolled (N = 205). Residents were 47% female, predominantly white (69%), and 84 years old, on average (SD = 10 years).

MEASUREMENTS

A comprehensive pain assessment protocol was used to evaluate pain severity and characteristics through medical record review, interviews with nursing home staff, physical examinations, as well as pain observation tools (Mobilization-Observation-Behavior-Intensity-Dementia Pain Scale and Pain Intensity Measure for Persons With Dementia). Known correlates were also assessed (agitation, depression, and sleep).

RESULTS

Experts' pain evaluations indicated that residents' usual pain was mild (mean = 1.6/10), and most experienced only intermittent pain (70%). However, 45% of residents experienced moderate to severe worst pain. Of residents, 90% received a pain therapy, with acetaminophen (87%) and opioids (32%) commonly utilized. Only 3% had a nondrug therapy documented in the medical record. The only resident characteristic that was significantly associated with pain severity was receipt of an opioid in the past week.

CONCLUSION

Using a comprehensive pain assessment protocol, we found that most nursing home residents with moderate to severe dementia had mild usual, intermittent pain and the vast majority received at least one pain therapy in the previous week. Although these findings reflect improvements in pain management compared with older studies, there is still room for improvement in that 45% of the sample experienced moderate to severe pain at some point in the previous week.

Nurses’ certainty and pain outcomes of nursing home residents with dementia: the mediating effect of pain assessment

Aim: This study aims to examine the associations of pain assessment scope, nurses’ certainty, patient outcomes, and cognitive and verbal characteristics of nursing home (NH) residents. Methods: This study used a descriptive correlational design and a convenience sample of 78 NH residents with dementia. Results: There are significant associations between the severity of dementia and the ability to self report symptoms in NH residents and nurses’ certainty of pain. Also, pain assessment scope does not mediate the relationship between nurses’ certainty and patient outcomes. Conclusion: Pain assessment in NH residents with dementia is very challenging for nurses due to multiple complex factors. Improved understanding of pain assessment in those residents and how it relates to certainty of pain and patient outcomes are crucial.

Pain Assessment in the Patient Unable to Self-Report: Clinical Practice Recommendations in Support of the ASPMN 2019 Position Statement

Pain is a subjective experience, unfortunately, some patients cannot provide a self-report of pain verbally, in writing, or by other means. In patients who are unable to self-report pain, other strategies must be used to infer pain and evaluate interventions. In support of the ASPMN position statement "Pain Assessment in the Patient Unable to Self-Report", this paper provides clinical practice recommendations for five populations in which difficulty communicating pain often exists: neonates, toddlers and young children, persons with intellectual disabilities, critically ill/unconscious patients, older adults with advanced dementia, and patients at the end of life. Nurses are integral to ensuring assessment and treatment of these vulnerable populations.
