The assessment and management of pain in the demented and non-demented elderly patient

Chronic Pain in the Elderly: Mechanisms and Perspectives

Chronic pain affects a large part of the population causing functional disability, being often associated with coexisting psychological disorders, such as depression and anxiety, besides cognitive deficits, and sleep disturbance. The world elderly population has been growing over the last decades and the negative consequences of chronic pain for these individuals represent a current clinical challenge. The main painful complaints in the elderly are related to neurodegenerative and musculoskeletal conditions, peripheral vascular diseases, arthritis, and osteoarthritis, contributing toward poorly life quality, social isolation, impaired physical activity, and dependence to carry out daily activities. Organ dysfunction and other existing diseases can significantly affect the perception and responses to chronic pain in this group. It has been proposed that elderly people have an altered pain experience, with changes in pain processing mechanisms, which might be associated with the degeneration of circuits that modulate the descending inhibitory pathways of pain. Aging has also been linked to an increase in the pain threshold, a decline of painful sensations, and a decrease in pain tolerance. Still, elderly patients with chronic pain show an increased risk for dementia and cognitive impairment. The present review article is aimed to provide the state-of-art of pre-clinical and clinical research about chronic pain in elderly, emphasizing the altered mechanisms, comorbidities, challenges, and potential therapeutic alternatives.

Determining the frailty status in patients who apply for home health care

Background To examine the relationship between an institutionally prepared standardized patient evaluation form and the Edmonton Frail Scale (EFS) in patients receiving home health care. Material and Methods Our prospective, observational study included 200 patients over the age of 18 who requested home health care, regardless of gender. The EFS and institutional data collection forms were applied consecutively on the same day to all patients included in the study. Results Among the 200 individuals recruited for the study, 59% were female and 41% were male; the overall average age was 80 years. According to the EFS results, 4.5% of the patients were classified as non-frail, 6% were vulnerable, and 89.5% had varying degrees of frailty (mild, moderate and severe). There was a significant positive correlation between EFS score and age (p

Care home residents’ quality of life and its association with CQC ratings and workforce issues: the MiCareHQ mixed-methods study

Background

Care home staff have a critical bearing on quality. The staff employed, the training they receive and how well they identify and manage residents’ needs are likely to influence outcomes. The Care Act 2014 (Great Britain. The Care Act 2014. London: The Stationery Office; 2014) requires services to improve ‘well-being’, but many residents cannot self-report and are at risk of exclusion from giving their views. The Adult Social Care Outcomes Toolkit enables social care-related quality of life to be measured using a mixed-methods approach. There is currently no equivalent way of measuring aspects of residents’ health-related quality of life. We developed new tools for measuring pain, anxiety and depression using a mixed-methods approach. We also explored the relationship between care home quality, residents’ outcomes, and the skill mix and employment conditions of the workforce who support them.

Objectives

The objectives were to develop and test measures of pain, anxiety and depression for residents unable to self-report; to assess the extent to which regulator quality ratings reflect residents’ care-related quality of life; and to assess the relationship between aspects of the staffing of care homes and the quality of care homes.

Design

This was a mixed-methods study.

Setting

The setting was care homes for older adults in England.

Participants

Care home residents participated.

Results

Three measures of pain, anxiety and low mood were developed and tested, using a mixed-methods approach, with 182 care home residents in 20 care homes (nursing and residential). Psychometric testing found that the measures had good construct validity. The mixed-methods approach was both feasible and necessary with this population, as the majority of residents could not self-report. Using a combined data set (n = 475 residents in 54 homes) from this study and the Measuring Outcomes in Care Homes study (Towers AM, Palmer S, Smith N, Collins G, Allan S. A cross-sectional study exploring the relationship between regulator quality ratings and care home residents’ quality of life in England. Health Qual Life Outcomes 2019;17:22) we found a significant positive association between residents’ social care-related quality of life and regulator (i.e. Care Quality Commission) quality ratings. Multivariate regression revealed that homes rated ‘good/outstanding’ are associated with a 12% improvement in mean current social care-related quality of life among residents who have higher levels of dependency. Secondary data analysis of a large, national sample of care homes over time assessed the impact of staffing and employment conditions on Care Quality Commission quality ratings. Higher wages and a higher prevalence of training in both dementia and dignity-/person-centred care were positively associated with care quality, whereas high staff turnover and job vacancy rates had a significant negative association. A 10% increase in the average care worker wage increased the likelihood of a ‘good/outstanding’ rating by 7%.

Limitations

No care homes rated as inadequate were recruited to the study.

Conclusions

The most dependent residents gain the most from homes rated ‘good/outstanding’. However, measuring the needs and outcomes of these residents is challenging, as many cannot self-report. A mixed-methods approach can reduce methodological exclusion and an over-reliance on proxies. Improving working conditions and reducing staff turnover may be associated with better outcomes for residents.

Future work

Further work is required to explore the relationship between pain, anxiety and low mood and other indicators of care homes quality and to examine the relationship between wages, training and social care outcomes.

Correlation between biomarkers of pain in saliva and PAINAD scale in elderly people with cognitive impairment and inability to communicate: descriptive study protocol

INTRODUCTION

Pain is an under-diagnosed problem in elderly people, especially in those with cognitive impairment who are unable to verbalise their pain. Although the Pain assessment in advanced dementia scale (PAINAD) scale is a tool recognised for its clinical interest in this type of patients, its correlation with the saliva biomarkers reinforced its utility. The aim of this research will be to correlate the scores of this scale with the levels of biomarkers of pain found in saliva samples of patients with cognitive impairment and inability to communicate.

METHODS AND ANALYSIS

This is an observational study. The level of pain will be evaluated using the PAINAD scale. Moreover, pain biomarkers, in particular secretory IgA and soluble tumour necrosis factor receptor type II, will be determined in saliva. Both assessments will be conducted in 75 patients aged over 65 years with advanced cognitive impairment and inability to communicate. The PAINAD scores will be correlated with the levels of these biomarkers of pain. A control group consisting of 75 healthy subjects aged over 65 years will be included in the study. Moreover, sociodemographic variables and variables related to pain, dementia and other clinical conditions will be recorded. The analysis will be performed with the statistical package SPSS V.22 and the software R.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the Andalusian Human Research Ethics Committee. In addition, this study has been financed by the Junta de Andalucía through a regional health research fund (Research code: PI-0357-2017). The results will be actively disseminated trough a high-impact journal in our study area, conference presentations and social media.

Persistent pain is a risk factor for frailty: a systematic review and meta-analysis from prospective longitudinal studies

Background

pain is prevalent in frail older adults; however, the association of pain and frailty has not been evaluated yet by a systematic assessment of prospective longitudinal studies.

Objective

we aimed to assess the association of persistent pain as a risk factor for frailty incidence, using data from longitudinal studies in a systematic review and meta-analysis.

Methods

publications were identified using a systematic search on PubMed, Embase, Cochrane Library and clinicaltrials.gov databases from inception to October 2017. Since heterogeneity across studies was high, we used random-effects meta-analysis to calculate the pooled relative risk for the association between persistent pain and the incidence of frailty. We investigated sources of heterogeneity among studies using meta-regression and stratified analyses.

Results

we included five prospective longitudinal studies with 13,120 participants (46% women, mean age from 59 to 85 years old). Participants with persistent pain at baseline had twice the risk of developing frailty during the follow-up (pooled RR = 2.22, 95% CI = 1.14-4.29). No variables were related to study heterogeneity in sensitivity analyses.

Conclusion

persistent pain was a risk factor for the development of frailty in a meta-analysis of longitudinal studies. Better understanding of the association between pain and frailty with proper evaluation of potential confounders could allow the development of targeted interventions.

Pain: The Neglect Issue in Old People's Life

BACKGROUND

As the elderly population increases dramatically, the chronic age-related disease should be noted. In the elderly, chronic pain is a common health problem.

METHODS

This search was performed in 3 databases (PubMed, Google Scholar, Embase). We have reviewed articles related to pain management in the elderly.

RESULT

The prevalence of pain in people aged above 60 is twice that in younger people. Pain is estimated to be 45-85 per cent in the elderly. Pain is not a part of the ageing process, but many older people can experience it. Perception of pain can be affected by environmental, emotional, cultural and cognitive factors. Pain in the elderly often remains untreated and misdiagnosed.

CONCLUSION

Pain management in elderly needs different approach because of unreported pain in this population, and usually they have multiple problems and comorbidities that complicate evaluation and treatment.

On the feasibility of accessing acute pain-related facial expressions in the human fetus and its potential implications: a case report

Supplemental Digital Content is Available in the Text.

Introduction:

Although pain facial assessment is routinely performed in term and preterm newborns by the use of facial expression–based tools such as the Neonatal Facial Coding System, the assessment of pain during the intrauterine life has not been extensively explored.

Objective:

Describe for the first time, an experimental model to assess and quantify responses due to acute pain in fetuses undergoing anaesthesia for intrauterine surgery recorded by high-resolution 4D ultrasound machines.

Methods/results-case report:

A 33-year-old pregnant woman had congenital left diaphragmatic hernia of poor prognosis diagnosed, and her fetus was treated by fetoscopic endotracheal occlusion. Later, during the removal of the fetal endotracheal balloon by ultrasound-guided puncture, we have recorded facial expressions of the foetus before and after the anaesthetic puncture by the use of 4D ultrasound recordings, which were presented to 3 blinded coders instructed to use the Neonatal Facial Coding System for acute pain facial coding. The procedure was safe and feasible.

Conclusion:

This is the first description of a recordable acute pain model in the human fetus by the use of a facial expression–based tool. The possibility to assess pain-related intrauterine behaviours would allow not only for the monitoring of the efficacy of anaesthetic procedures in the fetus but would also open the way to explore the evolution of pain-related facial responses during the fetal neurodevelopment. This method may pave the way for objective assessments of pain in fetuses, should it endure the steps of formal validation studies.

N-of-1 Randomized Trials of Ultra-Micronized Palmitoylethanolamide in Older Patients with Chronic Pain

BACKGROUND

Ultra-micronized palmitoylethanolamide (um-PEA) represents an attractive option for chronic pain control in complex older patients at higher risk of adverse effects with traditional analgesics.

OBJECTIVE

The aim of this study was to determine the effectiveness of um-PEA versus placebo on chronic pain intensity and function in individual geriatric patients.

DESIGN

We performed randomized, blinded N-of-1 trials with two 3-week um-PEA versus placebo comparisons, separated by 2-week washout periods.

PARTICIPANTS

The study included outpatients aged ≥ 65 years with chronic, non-cancer, non-ischemic pain in the back, joints, or limbs.

INTERVENTION

Patients were randomized to Um-PEA 600 mg or placebo twice daily.

MEASUREMENTS

Pain intensity was measured using an 11-point visual numeric scale. Functional impairment was measured using a Back Pain Functional Scale. Impact of each N-of-1 trial was measured on the clinician's intention to treat and confidence.

RESULTS

Ten of 11 eligible patients consented over 7 months [all female, mean age 83.2 years (SD 4.6)]. Three patients interrupted the trial: one had diarrhea (under placebo), one for low adherence, and one for intercurrent pneumonia. A small statistically significant effect in favor of um-PEA was seen at the mixed method analyses in two patients (effect size equal to 8% of the baseline pain). A statistically significant impact on function was found in one patient. After the trial, um-PEA was prescribed to four patients; in two patients the clinician changed their pre-trial intention to treat; the clinician confidence in the treatment plan either increased (5) or remained the same (2).

CONCLUSIONS

Our experience confirmed that N-of-1 trials may help make personalized evidence-based decisions in complex older patients, with special feasibility considerations. CLINICALTRIALS.GOV: NCT02699281.

Towards improved decision support in the assessment and management of pain for people with dementia in hospital: a systematic meta-review and observational study

Background

Pain and dementia are common in older people, and impaired cognitive abilities make it difficult for them to communicate their pain. Pain, if poorly managed, impairs health and well-being. Accurate pain assessment in this vulnerable group is challenging for hospital staff, but essential for appropriate management. Robust methods for identifying, assessing and managing pain are needed.

Aims and objectives

Two studies were undertaken to inform the development of a decision support tool to aid hospital staff in the recognition, assessment and management of pain. The first was a meta-review of systematic reviews of observational pain assessment instruments with three objectives: (1) to identify the tools available to assess pain in adults with dementia; (2) to identify in which settings they were used and with what patient populations; and (3) to assess their reliability, validity and clinical utility. The second was a multisite observational study in hospitals with four objectives: (1) to identify information currently used by clinicians when detecting and managing pain in patients with dementia; (2) to explore existing processes for detecting and managing pain in these patients; (3) to identify the role (actual/potential) of carers in this process; and (4) to explore the organisational context in which health professionals operate. Findings also informed development of health economics data collection forms to evaluate the implementation of a new decision support intervention in hospitals.

Methods

For the meta-review of systematic reviews, 12 databases were searched. Reviews of observational pain assessment instruments that provided psychometric data were included. Papers were quality assessed and data combined using narrative synthesis. The observational study used an ethnographic approach in 11 wards in four UK hospitals. This included non-participant observation of 31 patients, audits of patient records, semistructured interviews with 52 staff and four carers, informal conversations with staff and carers and analysis of ward documents and policies. Thematic analysis of the data was undertaken by the project team.

Results

Data from eight systematic reviews including 28 tools were included in the meta-review. Most tools showed moderate to good reliability, but information about validity, feasibility and clinical utility was scarce. The observational study showed complex ward cultures and routines, with variations in time spent with patients, communication patterns and management practices. Carer involvement was rare. No pain decision support tools were observed in practice. Information about pain was elicited in different ways, at different times, by different health-care staff and recorded in separate documents. Individual staff made sense of patients’ pain by creating their own ‘overall picture’ from available information.

Limitations

Grey literature and non-English-language papers were excluded from the meta-review. Sample sizes in the observational study were smaller than planned owing to poor documentation of patients’ dementia diagnoses, gatekeeping by staff and difficulties in gaining consent/assent. Many patients had no or geographically distant carers, or a spouse who was too unwell and/or reluctant to participate.

Conclusions

No single observational pain scale was clearly superior to any other. The traditional linear concept of pain being assessed, treated and reassessed by single individuals did not ‘fit’ with clinical reality. A new approach enabling effective communication among patients, carers and staff, centralised recording of pain-related information, and an extended range of pain management interventions is proposed [Pain And Dementia Decision Support (PADDS)]. This was not tested with users, but a follow-on study aims to codesign PADDS with carers and clinicians, then introduce education on staff/patient/carer communications and use of PADDS within a structured implementation plan. PADDS will need to be tested in differing ward contexts.

Efficacy of ultra-micronized palmitoylethanolamide (um-PEA) in geriatric patients with chronic pain: study protocol for a series of N-of-1 randomized trials

BACKGROUND

Chronic pain in older people is highly prevalent, often underestimated, and associated with adverse outcomes. Most available analgesic drugs are often either ineffective or not tolerated, with many side effects. Palmitoylethanolamide (PEA) is an endogenous widely distributed N-acylethanolamina involved in neuroinflammation and pain-generating processes. Formulations containing ultra-micronized palmitoylethanolamide (um-PEA) are available but their effectiveness on chronic pain in highly heterogeneous geriatric patients is not clear and probably not generalizable. We planned to adopt the N-of-1 trial approach to test the effectiveness of um-PEA objectively at the individual level in our older outpatients.

METHODS/DESIGN

Persons 65 years or older referring to the Geriatric Unit of the Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico of Milan complaining of noncancer chronic pain of any origin will be eligible. Each trial will be a placebo-controlled randomized crossover trial including two um-PEA (600 mg twice a day) and placebo treatment pairs. The um-PEA or placebo 3-week periods will be separated by 2-week washout intervals to overcome possible carryover effects. Pain intensity, need of on-demand analgesic medications, and impact on daily activities will be evaluated. Cognitively impaired patients will be eligible as long as an expression of pain can be recognized and its frequency assessed by a caregiver. Trial results will be discussed with the patient or caregiver and the treating physician to decide whether to continue the treatment. The impact of the N-of-1 approach on the physician's management plan and confidence will be assessed. We will secondarily meta-analyze the performed N-of-1 trials to obtain an estimate of the average effect of um-PEA compared with placebo using a frequentist and Bayesian approach.

DISCUSSION

While pursuing an ultimate clinical objective, i.e. to empirically and objectively decide the best treatment choice for an individual older patient with chronic pain, these series of geriatric N-of-1 trials on PEA will bring the principles of evidence-based medicine into the care of patients not usually represented in conventional randomized controlled trials, and realize a patient-centered outcome approach necessary to improve appropriate prescribing in elderly patients with multimorbidity and polypharmacy.

The type and prevalence of the use of analgesics among inpatients in a geriatric psychiatry department

OBJECTIVES

The association between the presence of pain and mental disorder is well known. The extent of pain treatment in psychiatric patients is estimated to be high, but there is a lack of recent studies focusing on analgesic treatment in patients with mental disorders. The use of analgesics can be associated with side effects, and it is possible that analgesics are not the correct treatment for chronic pain among patients with mental disorders.

METHODS

Data were obtained among inpatients in a geriatric psychiatry department at Aarhus University Hospital, Risskov, Denmark, between 1 April 2013 and 1 October 2013. The study examines the extent of analgesic use by patients at admission with a follow up at discharge to note any change during hospitalization.

RESULTS

A total of 89 patients aged 68 years or older were included (56 women, 33 men). At admission, 51.7% used analgesics, and this number did not change significantly from admission to discharge. A statistically significant increased risk of analgesic use was found in females (odds ratio 4.0). The indications for analgesic use were not present in 34.5% of the pain-treated patients at admission. At discharge, this number had been reduced to 23.1%. Paracetamol was the drug most frequently used, followed by opioids.

CONCLUSIONS

The use of analgesics among aged psychiatric inpatients is high. An increased focus on this topic is recommended.

Pain assessment for people with dementia: a systematic review of systematic reviews of pain assessment tools

BACKGROUND

There is evidence of under-detection and poor management of pain in patients with dementia, in both long-term and acute care. Accurate assessment of pain in people with dementia is challenging and pain assessment tools have received considerable attention over the years, with an increasing number of tools made available. Systematic reviews on the evidence of their validity and utility mostly compare different sets of tools. This review of systematic reviews analyses and summarises evidence concerning the psychometric properties and clinical utility of pain assessment tools in adults with dementia or cognitive impairment.

METHODS

We searched for systematic reviews of pain assessment tools providing evidence of reliability, validity and clinical utility. Two reviewers independently assessed each review and extracted data from them, with a third reviewer mediating when consensus was not reached. Analysis of the data was carried out collaboratively. The reviews were synthesised using a narrative synthesis approach.

RESULTS

We retrieved 441 potentially eligible reviews, 23 met the criteria for inclusion and 8 provided data for extraction. Each review evaluated between 8 and 13 tools, in aggregate providing evidence on a total of 28 tools. The quality of the reviews varied and the reporting often lacked sufficient methodological detail for quality assessment. The 28 tools appear to have been studied in a variety of settings and with varied types of patients. The reviews identified several methodological limitations across the original studies. The lack of a 'gold standard' significantly hinders the evaluation of tools' validity. Most importantly, the samples were small providing limited evidence for use of any of the tools across settings or populations.

CONCLUSIONS

There are a considerable number of pain assessment tools available for use with the elderly cognitive impaired population. However there is limited evidence about their reliability, validity and clinical utility. On the basis of this review no one tool can be recommended given the existing evidence.

Instruments for assessing pain in persons with severe dementia

Through an integrative literature review involving the CINAHL, Cochrane, Embase, LILACS, PsycINFO, PubMed databases, tools available in the literature for assessing pain in individuals with severe dementia were identified along with versions validated for use in Brazil. We found 1501 relevant articles which, after selection of abstracts and full reading, yielded a final sample of 33 articles. The analysis enabled the identification of 12 instruments: ABBEY PAIN SCALE; ADD; CNPI; CPAT; DOLOPLUS-2; MOBID and MOBID-2; MPS; NOPPAIN; PACSLAC; PADE; PAINAD and PAINE. Despite the wide variety of tools for assessing pain in individuals with severe dementia worldwide, it was observed that only four are available in Portuguese, of which two are culturally adapted for Brazilian Portuguese (NOPPAIN and PACSLAC) and two validated for Portuguese of Portugal (DOLOPLUS and PAINAD), pointing to the need for further validation of instruments for use in Brazil.

Post-operative pain management practices in patients with dementia - the current situation in Finland

The aim of this study is to describe current post-operative pain management practices for patients with dementia and hip fracture in Finland. Older adults with hip fracture are at high risk of under treatment for pain, especially if they also have a cognitive disorder at the stage of dementia. Previous studies have provided limited information about the quality of acute pain treatment for persons with dementia. In this study data concerning current pain management practices was collected by questionnaire from 333 nursing staff. They worked in surgical wards of seven universities and ten city-centre hospitals. The response rate to the questionnaire was 53%. The data was analysed using factor analysis and parametric methods. Half the respondents (53%) considered that post-operative pain management was sufficient for patients with dementia. Less than one third of respondent nurses reported that pain scales were in use on their unit: the most commonly used scale was VAS. The use of pain scales was significantly related to the respondents' opinion of the sufficiency of post-operative pain management in this patient group (p<0.001). The findings can be utilised in nursing practice and research when planning suitable complementary educational interventions for nursing staff of surgical wards. Further research is needed to explain the current situation of pain management practices from the viewpoint of patients with dementia.
