Assessing pain in older people with normal, mildly impaired or severely impaired cognition

Pain is a relatively common experience among older people, but unrelieved pain has significant functional, cognitive and emotional consequences for this population. A comprehensive and accurate pain assessment is essential for effective pain management. Self-report tools are suitable to assess pain in older people with normal or mildly impaired cognition, while observational tools are suitable for use with those with significant cognitive impairment or communication difficulties. However, pain assessment in older people can be challenging. The use of one tool on its own is rarely sufficient and it is crucial to involve family carers in assessment of pain in older people with severe cognitive impairment. This article discusses different tools and strategies, including the benefits and limitations, for assessing pain in older people.

Pain in People with Advanced Dementia: The Opinions of Kazakh Medical Students

Purpose

The medical students’ attitude toward pain in people with advanced dementia, while constituting an important factor in care, has rarely been assessed to date. The aim of our study was thus to perform such assessment in medical students in Kazakhstan, to enable an improvement of the existing curriculum (like we previously did in Poland).

Materials and Methods

We analyzed the knowledge about pain using a short anonymous questionnaire, which was completed by 112 students of the Medical University of Aktobe, Kazakhstan.

Results

On average, students listed symptoms of 1.4 ± 1.2 (out of 6 analyzed) pain areas (median 2.0). The symptoms related to changes in mental status were suggested the most often (57 students: 50.9%). The students who indicated these symptoms also listed a higher number of symptoms from the remaining domains (1,1 ± 1.0 [median 1.0] vs 0.6 ± 0.8 [median 0.0]; p<0.01). Observational methods in the assessment of the severity of pain in people with dementia were indicated by 44 students (39.3%), but only one participant (0.9%) was able to name an observational scale for pain assessment. Correct answers regarding pain treatment rules were presented by 18 students (16.0%), and the answers of the next 47 participants (42.0%) were very general but suggested the same treatment no matter what the cognitive status.

Conclusion

The study revealed gaps in the knowledge of Kazakh medical students regarding pain in advanced stages of dementia. Demographic changes, combined with the coexistence of pain with dementia, indicate that medical students worldwide must have sufficient knowledge and skills to adequately care for the continually growing number of people with these conditions. It is imperative in countries like Kazakhstan, where the dementia burden was unrecognized until now, but it will blow up in the near future.

Pain in Advanced Stages of Dementia: The Perspective of Medical Students

Background and objective: The number of studies related to medical students' attitude toward pain is limited. The aim of our study was, thus, to assess the medical students' knowledge of pain assessment and treatment in advanced stages of dementia in order to improve the existing curriculum in this area. Material and methods: We analyzed the medical students' knowledge about pain in advanced dementia based on a short questionnaire. The research was anonymous. The questionnaire was completed by 147 students. Results: The students most often suggested that pain in patients with advanced dementia could be manifested via body language and facial expression (107 students-72.8% and 100 students-68.0%, respectively). Vocalization was the third most frequently reported pain manifestation (84-57.1%). Other groups of pain symptoms (changes in activity patterns, changes in interpersonal interactions, and mental status changes) were indicated less often (p < 0.0001). Only five students (3.4%) listed the DOLOPLUS behavioral pain scale as an assessment tool for patients with advanced dementia, and 16 (10.9%) indicated observational scale elements or a necessity to observe the patient. Still, 110 students (74.5%) correctly characterized pain treatment in patients with advanced dementia. Conclusions: To the best of our knowledge, our study is pioneering in defining the deficits of medical students' knowledge on pain assessment and treatment in patients with advanced dementia. We highlighted knowledge gaps in the area of pain assessment which might make medical students incapable of proper pain treatment. Following the International Association for the Study of Pain considerations regarding the need for excellence in pain education, these results can contribute to the improvement of existing medical curricula in Poznan University of Medical Sciences to include pain management in dementia in a more "patient-centered" way in order to increase future staff's competency and to assure a better quality of care.

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.

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.

Pain and dementia: an overview of the literature

This paper discusses how pain and its undertreatment impacts upon older people with dementia. It outlines how the contributing factors to the underassessment of pain are numerous and includes dementia-related factors (such as loss of communication ability) and health professional-related factors (such as inappropriate or non-application of a pain-assessment tool and deficit knowledge regarding pain mechanisms and/or dementia). Pharmacological and non-pharmacological treatment options for pain are noted as important but are not the focus of this paper.

Pain assessment in the recovery room

The assessment and management of pain in the acute hospital setting is an important issue for practitioners (Layman Young et al 2005). Despite advances in pain management (Fotiadis et al 2004, Powell et al 2004, Wu & Richman 2004) and the use of multimodal analgesic techniques in the theatre/recovery environment (Jin & Chung 2001), for a variety of reasons (Turk & Okifuji 1999, Pasero 2003), patients' reports of pain following surgery suggest that it remains problematic (Rawal 2002, Brown 2004, Coll et al 2004). In the recovery room disorientation, anxiety, fear and nausea may add to and alter patients' perception of pain, making it crucial that recovery room practitioners understand pain and pain assessment. This article outlines and critiques pain assessment tools that may be used to enhance pain management practices in the recovery room.
