A Comparison of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC) and Pain Assessment in Advanced Dementia Scale (PAINAD)

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.

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.

Level of implementation of pain management and early mobilization strategies to prevent delirium in geriatric trauma patients: A mixed-methods study

BACKGROUND

Pain management and early mobilization strategies are recommended in clinical practice guidelines for the prevention of delirium in older adults. However, available data on the implementation of these strategies in trauma are limited.

AIMS

To describe the use of pain management and early mobilization strategies in older adults at a level I trauma center, as well as the facilitators and barriers to their implementation.

METHODS

A convergent mixed methods study was used. Quantitative data were collected from sixty medical records. Qualitative data was collected through a focus group with healthcare providers to explore their perspectives regarding the use of the target practices and on barriers and facilitators to their implementation. Descriptive statistics were calculated, and a thematic analysis using an inductive and deductive interpretative descriptive approach was undertaken.

RESULTS

A question on the presence/absence of pain was the most frequently documented pain assessment method. Pain assessment was poorly documented. Frequencies of non-opioid and opioid administrations were similar, but non-pharmacological strategies were not widely used. The first mobilization was performed quickly and was most commonly to a chair. The focus group discussion confirmed many of the data collected in the medical records. Barriers to implementing the targeted strategies were primarily related to organizational context and facilitation processes.

CONCLUSIONS

Areas for improvement were identified including pain assessment, the use of non-pharmacological pain management strategies and ambulation as a mobilization strategy. Our findings will serve as a starting point for optimizing and adapting practices for geriatric trauma patients and evaluating their impact.

Association Between Documented Severe Pain and Cognitive Impairment in Home Health Care Patients: Results from the National Outcome and Assessment Information Set Data

Background: Despite the growing importance of home health care (HHC) in the care of older adults with cognitive impairment, limited evidence exists about factors associated with documented severe pain among older adults receiving HHC. Methods: This secondary data analysis used a 5% random national sample of the 2017 national Outcome and Assessment Information Set (OASIS) data. Multivariable Poisson regression model was used to examine the association between documented severe pain, cognitive impairment, and a range of sociodemographic, clinical, and cognitive factors. Results: HHC patients (n = 183,038) were mean age 79.7 years, 61.7% female, and 78.6% non-Hispanic White. In multivariable models, cognitive impairment was associated with lower likelihood of documented severe pain (prevalence ratio [PR] = 0.96, confidence interval [CI] = [0.94-0.98]). Other factors independently associated with less documented severe pain included Hispanic ethnicity (PR = 0.92, CI = [0.89-0.95]), the oldest (≥85 years) groups (PR = 0.65, CI = [0.63-0.66]), male patients (PR = 0.83, CI = [0.82-0.85]), those with a formal diagnosis of Alzheimer's Disease Related Dementias (PR = 0.67, CI = [0.65-0.69]), and patients with verbal- and speech-related difficulty (PR = 0.83, CI = [0.80-0.86]). Patients with history of falls (PR = 1.18, CI = [1.16-1.20]), positive screen on the Patient Health Questionnaire-2 (PR = 1.36, CI = [1.31-1.41]), shortness of breath (PR = 1.14, CI = [1.12-1.14]), anxiety daily (PR = 1.16, CI = [1.14-1.18]), and anxiety daily or more often (PR = 1.40, CI = [1.37-1.43]) were more likely to have documented severe pain. Conclusions: HHC patients with cognitive impairment were less likely to have documented severe pain even with a range of sociodemographic, clinical, functional, and cognitive characteristics were considered. These findings may reflect a link between cognitive impairment missed opportunities for clinicians to provide pain management. Tailored interventions are needed to better assess and manage pain in this vulnerable group of HHC patients.

Pain Management in the Postoperative Period for People With Dementia: An Integrative Review

Objective

With the increased global prevalence of older people with dementia, more will present for surgery over the coming decades. Therefore, the objective of this study was to synthesize the existing research about how pain in managed for people with dementia in the postoperative period and discuss the implications for clinical practice.

Methods

For this integrative review, the Cumulative Index to Nursing and Allied Health literature, Medline/Pubmed, ProQuest, ERIC, and Health Source Nursing were searched to identify original empirical research published between 2000 and 2021. Tasks were divided between reviewers to ensure independent study selection, data extraction, and risk of bias assessment.

Results

Eleven articles were eligible. The evidence is incompletely developed therefore the review focused on pain assessment, the types and amount of pain relief, that people with dementia receive less analgesia than people without dementia and the challenges for effective pain management. Most studies were surgery for hip fracture so there is scope to look at outcomes for other types of surgery. Analgesia was administered but it was noted that even over a 20-year period, people with dementia received less than cognitively intact people. Pain management could have a stronger evidence-base with more psychometric development of pain assessment tools. Challenges are due to the impaired ability of the person with dementia to communicate pain and that clinicians have difficulty understanding pain behavior in people with dementia.

Conclusion

Adequate pain management for people with dementia in the postoperative period is important for a faster and better recovery.

A Descriptive Study of Treatment of Pain in Acute Care for Patients Living With Dementia

BACKGROUND

During the hospital stay pain is very common among patients living with dementia.

METHODS

Descriptive data was obtained from chart review and included age, gender, race, comorbidities and admitting diagnosis.

AIMS

The purpose of this study was to describe pain among patients living with dementia, the use of pharmacologic and nonpharmacologic treatment, and to compare treatments among those with and without pain.

DESIGN

This was a descriptive study using baseline data from the first 233 participants from the study "Testing the Implementation of Function Focused Care for Acute Care Using the Evidence Integration Triangle (FFC-AC-EIT)".

PARTICIPANTS/SUBJECTS

The mean age of participants was 83 (SD=5) and the majority was female (65%) and White (67%) with evidence of dementia (based on a mean Saint Louis University Mental Status Test = 7.23, SD=5.85).

RESULTS

Overall 98 (42%) participants had pain and 135 (58%) no pain. Only 14 (6%) participants received no nonpharmacologic or pharmacologic interventions for pain and five of these individuals had pain. The most frequently used pharmacologic intervention among all participants was acetaminophen (n = 121, 52%), then tramadol (n = 19, 8%). Comfort measures and general nonpharmacologic approaches were the most frequently used non-pharmacologic approaches, then physical activity and therapeutic communication. From admission to discharge, there was a trend towards a decrease in pain. There was more use of opioids, physical activity, and therapeutic communication in the no pain group versus the pain group.

CONCLUSIONS

The majority of hospitalized medical patients living with dementia were treated for pain, but an ongoing focus is needed to assure optimal pain management for all patients.

Measuring Pain in Aphasia: Validity and Reliability of the PACSLAC-D

BACKGROUND

Post-stroke pain in patients with an inability to communicate is not systematically assessed and therefore not sufficiently treated. This stresses the need to study pain assessment instruments that do not require good communication skills.

AIM

To examine the validity and reliability of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate - Dutch version (PACSLAC-D) in stroke patients with aphasia.

METHOD

Sixty stroke patients (mean age 79.3 years, standard deviation [SD] 8.0), of whom 27 had aphasia were observed during rest, activities of daily living (ADL), and physiotherapy using the Pain Assessment Checklist for Seniors with Limited Ability to Communicate - Dutch version (PACSLAC-D). The observations were repeated after two weeks. To examine convergent validity, correlations between the PACSLAC-D, self-report pain scales, and the clinical judgment of a health care professional (pain present yes/no) were used. To examine discriminative validity, differences in pain were investigated between rest and ADL, in patients who use pain medication and those who do not, and in patients with and without aphasia. Internal consistency and test-retest reliability were assessed to determine reliability.

RESULTS

Convergent validity failed to meet the acceptable threshold during rest but was adequate during ADL and physiotherapy. Discriminative validity was only adequate during ADL. The internal consistency was 0.33 during rest, 0.71 during ADL, and 0.65 during physiotherapy. Test-retest reliability varied from poor during rest (intraclass correlation coefficient [ICC] = 0.07; 95% confidence interval [CI]: -0.40-0.51) to excellent during physiotherapy (ICC = 0.95; 95% CI: 0.83-0.98).

CONCLUSIONS

The PACSLAC-D captures pain in patients with aphasia who are unable to self-report, during ADL and physiotherapy, but may be less accurate during rest.

Psychometric evaluation of the Pain Assessment in Advanced Dementia scale in an acute general hospital setting

BACKGROUND

People with dementia are at risk of unplanned hospital admissions and commonly have painful conditions. Identifying pain is challenging and may lead to undertreatment. The psychometric properties of the Pain Assessment in Advanced Dementia (PAINAD) scale, in medical inpatients with dementia have not been evaluated.

METHODS

A secondary data analysis from a longitudinal study of 230 people with dementia admitted to two acute general hospitals in London, UK. Internal consistency, inter-rater reliability, test-retest reliability, concurrent validity, construct validity and discriminant validity of PAINAD were tested at rest and in movement.

RESULTS

This predominantly female (65.7%) sample had a mean age of 87.2 (Standard Deviation; SD = 5.92) years. Inter-rater reliability showed an intra-class correlation (ICC) of 0.92 at rest and 0.98 in movement, test-retest reliability ICC was 0.54 at rest and 0.66 in movement. Internal consistency was 0.76 at rest and 0.80 in movement (Cronbach's α). Concurrent validity was weak between PAINAD and a self-rating level of pain (Kendall's Tau; τ = 0.29; p > 0.001). There was no correlation between PAINAD and a measure of behavioural and psychological symptoms of dementia, suggesting no evidence of convergent validity. PAINAD scores were higher during movement than rest, providing evidence of discriminant validity (z = -8.01, p < 0.001).

CONCLUSIONS

We found good inter-rater reliability and internal consistency. The test-retest reliability was modest. This study raises concerns about the validity of the PAINAD in general acute hospitals. This provides an insight into pain assessment in general acute hospitals which may inform further refinements of the PAINAD.

Facial Expressions Based Automatic Pain Assessment System

Pain assessment is used to improve patients’ treatment outcomes. Human observers may be influenced by personal factors, such as inexperience and medical organizations are facing a shortage of experts. In this study, we developed a facial expressions-based automatic pain assessment system (FEAPAS) to notify medical staff when a patient suffers pain by activating an alarm and recording the incident and pain level with the date and time. The model consists of two identical concurrent subsystems, each of which takes one of the two inputs of the model, i.e., “full face” and “the upper half of the same face”. The subsystems extract the relevant input features via two pre-trained convolutional neural networks (CNNs), using either VGG16, InceptionV3, ResNet50, or ResNeXt50, while freezing all convolutional blocks and replacing the classifier layer with a shallow CNN. The concatenated outputs in this stage is then sent to the model’s classifier. This approach mimics the human observer method and gives more importance to the upper part of the face, which is similar to the Prkachin and Soloman pain intensity (PSPI). Additionally, we further optimized our models by applying four optimizers (SGD/ADAM/RMSprop/RAdam) to each model and testing them on the UNBC-McMaster shoulder pain expression archive dataset to find the optimal combination, InceptionV3-SGD. The optimal model showed an accuracy of 99.10% on 10-fold cross-validation, thus outperforming the state-of-the-art model on the UNBC-McMaster database. It also scored 90.56% on unseen subject data. To speed up the system response time and reduce unnecessary alarms associated with temporary facial expressions, a select but effective subset of frames was inspected and classified. Two frame-selection criteria were reported. Classifying only two frames at the middle of 30-frame sequence was optimal, with an average reaction time of at most 6.49 s and the ability to avoid unnecessary alarms.

Invariance of the PAINAD Scale Between the Black and White Residents Living With Dementia

The purpose of this study was to test the reliability and validity of the Pain Assessment in Advanced Dementia (PAINAD) and particularly consider whether or not this measure was invariant when used among the Black and White residents. Baseline data from an implementation study testing that included a sample of 553 residents, 30% of who were Black, from 55 nursing were included in this study. The Winsteps statistical program was used to perform the Rasch analysis and evaluate the reliability and validity of the measure based on internal consistency, infit and outfit statistics, mapping, and a differential item functioning (DIF) analysis. The AMOS statistical program was used for confirmatory factor analysis. The findings supported the reliability and validity of the PAINAD when used with these individuals and demonstrated that there was no evidence of invariance between the Black and White residents. All the items fit the model, but there was not a good spread of the items across the pain level of the participants. The majority of the participants (75%) were so low in pain signs or symptoms that they could not be differentiated. Based on the clinical practice and observations, it is recommended that additional items can be added to the measure such as observing the individual for evidence of resisting care, retropulsion when trying to stand, hitting or kicking when turning in bed, hitting or kicking when transferring from bed to chair, hitting or kicking when ambulating, or hitting or kicking when raising arms, less engagement with others, and decreased participation in the activities previously enjoyed.

Insights to Identifying and Managing Pain in Persons With Dementia in Long-Term Care: A Mixed Methods Study Comparing the Abbey Pain Scale and Pain Assessment in Advanced Dementia Scale

Pain is usually identified by specific behaviors driven by the need for relief; however, persons with dementia present a unique challenge for nurses in assessing and managing pain. The aim of this mixed methods study was to explore the relationship between two observational pain scales, expressed need-driven behaviors, and likelihood of medication administration for persons with dementia. The qualitative strand examined nurses' perceptions regarding facilitators and barriers to pain scale use. Quantitative data analysis indicated the Abbey Pain Scale was significantly correlated with behaviors (r[26] = 0.41, p < 0.05) and approached significance with medication administration (r[26] = 0.35, p = 0.067). Qualitative analysis identified three core themes: (a) Challenges in Assessing Persons With Dementia for Pain; (b) Facilitators and Barriers to Pain Management; and (c) Difficulty Caring for Persons With Dementia. Clinical implications suggest the need for a systematic, consistent method of observing pain-related behaviors in persons with dementia. [Journal of Gerontological Nursing, 47(2), 21-30.].

Probable Pain on the Pain Assessment in Impaired Cognition (PAIC15) Instrument: Assessing Sensitivity and Specificity of Cut-Offs against Three Standards

Observational pain scales can help to identify pain in persons with dementia who may have difficulty expressing pain verbally. The Pain Assessment in Impaired Cognition-15 (PAIC15) covers 15 items that indicate pain, but it is unclear how probable pain is, for each summed score (range 0–45). We aimed to determine sensitivity and specificity of cut-offs for probable pain on the PAIC15 against three standards: (1) self-report when able, (2) the established Pain Assessment in Advanced Dementia (PAINAD) cut-off of 2, and (3) observer’s overall estimate based on a series of systematic observations. We used data of 238 nursing home residents with dementia who were observed by their physician in training or nursing staff in the context of an evidence-based medicine (EBM) training study, with re-assessment after 2 months in 137 residents. The area under the ROC curve was excellent against the PAINAD cut-off (≥0.8) but acceptable or less than acceptable for the other two standards. Across standards and criteria for optimal sensitivity and specificity, PAIC15 scores of 3 and higher represent possible pain for screening in practice, with sensitivity and specificity against self-report in the 0.5 to 0.7 range. While sensitivity for screening in practice may be too low, a cut-off of 4 is reasonable to indicate probable pain in research.
