Psychometric evaluation of the Orofacial Pain Scale for Non-Verbal Individuals as a screening tool for orofacial pain in people with dementia

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.

Pain in Dementia: An Empirical Test of a Common Assumption

Numerous, and often largely overlapping, observational pain assessment tools have been developed specifically to assess pain in older adults with dementia under the assumption that a specialized approach is necessary to evaluate pain in this population. However, this assumption has never been tested empirically. As an empirical test of this implicit assumption, our goal was to compare existing tools for people living with dementia (with respect to psychometric properties), not only against each other, but also against a tool developed for a different population with cognitive impairments. Videos of older adults with severe dementia recorded in long-term care settings were coded for pain behaviors in the laboratory. Trained coders coded pain behaviors in video segments of older adults with dementia during a quiet baseline condition as well as during a physical examination (designed to identify painful areas), using various observational pain assessment tools. An observational measure of agitation was employed to facilitate the assessment of discriminant validity. Consistent with our expectations, all pain tools (including the tool developed for younger people with cognitive impairments) successfully differentiated between painful and nonpainful states, with large effect sizes. This was the first study to compare tools specifically developed to assess pain in people living with dementia to a tool developed for a different population. Given that all tools under study showed satisfactory psychometric properties when tested on persons with dementia, this study suggests that the assumption that different tools are necessary for different populations with cognitive impairments cannot be taken for granted. PERSPECTIVE: This article challenges an implicitly held assumption that specialized tools are needed to assess pain in different populations with cognitive impairments. Given commonalities in pain expression across populations, further research is needed to determine whether population-specific tools are needed.

Oral Health Problems Among Flemish and Dutch Nursing Home Residents Assessed by Nondental Caregivers Using the Novel Oral Health Section for Inclusion in interRAI

Background and Objectives

Oral health of older adults in nursing homes is poor, which can negatively affect general health and well-being. Most oral health problems are preventable with good oral hygiene and regular dental check-ups. Caregivers can help improve residents' oral health through regular oral health assessments. The interRAI instrument used in Long-Term Care Facilities to evaluate older adults' health and well-being, has the potential to integrate oral care into general care planning. The recently optimized Oral Health Section for inclusion in the interRAI instruments (OHS-interRAI) enables nondental caregivers to identify residents requiring help with oral hygiene and/or a dental referral. This study reports the first data obtained using the OHS-interRAI, describing the oral health situation of older adults in Flemish and Dutch nursing homes.

Research Design and Methods

In this cross-sectional study, interRAI Long-Term Care Facilities data, including OHS-interRAI data, were collected from October 2020 to January 2023 and analyzed from 417 and 795 persons aged 65 years or older in Flemish and Dutch nursing homes, respectively.

Results

Most common oral health problems were poor oral hygiene and compromised teeth. Differences in oral health were found between Flemish and Dutch residents. Flemish residents had significantly more problems with chewing, dry mouth, oral and denture hygiene, and tongue condition than their Dutch counterparts. They also had a higher need for help with oral hygiene (19.4% vs 14.0%), and a dental referral (36.8% vs 20.9%). Older adults in Flemish nursing homes (20.3%) had significantly fewer dental check-ups than those in Dutch nursing homes (73.5%).

Discussion and Implications

The use of the OHS-interRAI by nondental caregivers identified at least one-third of the residents requiring help with oral hygiene and/or a dental referral. By means of trigger algorithms (Collaborative Action Points), the OHS-interRAI enables the integration of oral care into general care planning.

Prevalence of orofacial pain in individuals with mild cognitive impairment or dementia: A systematic review and meta-analysis

BACKGROUND

This systematic review investigated the prevalence of orofacial pain in patients with mild cognitive impairment (MCI) or dementia.

MATERIALS AND METHODS

The search was conducted in five databases (Medline (Ovid), Embase (Ovid), CINAHL, Scopus and LILACS), in three grey literature sources and in included articles' reference lists. Three independent reviewers performed study selection, quality appraisal and data extraction. The risk of bias was assessed with the National Institutes of Health tool. Prevalence was calculated using the random-effects model. Subgroup analysis and meta-regression were used to explore the heterogeneity of results.

RESULTS

The database and grey literature search led to 12 246 results, from which nine studies were included; a further four were selected through citation searching. The total sample comprised 6115 patients with dementia and 84 with MCI. All studies had high risk of bias. The overall estimated pooled prevalence of orofacial pain among dementia participants was 19.0% (95% CI, 11.0%-27.0%; I 2, 97.1%, P < .001). Only one study included MCI participants, among which the prevalence of orofacial pain was 20.5%. Subgroup analysis demonstrated that the different sources of diagnosis might explain the heterogeneity. A higher prevalence of orofacial pain was observed in dementia participants aged over 80 years or living in nursing homes. Meta-regression analysis showed a nonlinear relationship between age and the prevalence of orofacial pain.

CONCLUSIONS

The pooled data from the primary studies revealed that 2 out of 10 patients with dementia have orofacial pain. Further research is needed to clarify the magnitude in individuals with MCI.

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.

An umbrella review on the association between factors of oral health and cognitive dysfunction

An increasing number of systematic reviews and meta-analyses have been published on the association between oral health and cognitive dysfunction, also known as oral-cognitive links. However, there is great diversity in the oral and cognitive factors included in these studies, with different opinions for clinical practice drawn from the evidence. To understand which oral and cognitive factors are involved in those associations, we conducted an umbrella review of 28 systematic reviews, including 12 meta-analyses, on oral-cognitive links. We found that (a) periodontal diseases, oral microbiome, and dementia were frequently studied, while other factors, such as mastication and mild cognitive impairment, were less commonly investigated, and (b) severe deterioration of oral health, such as severe periodontitis or extensive tooth loss, rather than the presence of oral diseases alone, was strongly associated with cognitive dysfunction. In conclusion, the diversity of oral and cognitive factors included in the review studies reflects the complexity of oral-cognitive links. Clarifying the factors helps to form evidence-based clinical advice for healthcare.

Oral health care services for community-dwelling older people with dementia: A scoping review

OBJECTIVE

To assess whether, and if so, which oral health care services for community-dwelling older people with dementia are available.

BACKGROUND

Oral health in people with dementia is poor compared with people without dementia. Although multiple oral health care interventions have previously been studied for older people living in nursing homes, little is known about interventions or services for community-dwelling older people with dementia.

MATERIALS AND METHODS

A literature search was performed in the databases Pubmed, Embase and CINAHL. The following search terms were used: "Dementia", "Oral health", "Dental health services" and "Older person". The term "dental health services" was intended to be an as broad as possible construct because limited search results were expected.

RESULTS

The search generated 1624 unique references, of which seven studies were eligible for inclusion (four cohort studies, one cross-sectional study, and two qualitative studies). The included studies described two actual oral health care services: a telephone help line on oral health and dementia, and a mobile geriatric dental programme in adult day health centres. A need was found for services and strategies specific to community-dwelling older people with dementia. One identified solution was an intervention with individually tailored daily oral hygiene self-care supported by the informal caregiver. Furthermore, increasing accessibility of oral health care professionals with treatment at other locations than their own practices, better collaboration between health care professionals and preventive oral health care are highly necessary.

CONCLUSION

There is limited evidence on the availability of oral health care services for community-dwelling older people with dementia, while a need was found for oral health care services that focus on good accessibility, oral hygiene self-care, preventive strategies and collaboration among health care professionals.

Dental Pain in Care Homes: Is It a Phenomenon? A Systematic Review of the Literature

Background: Evidence suggests that 80% of residents living in nursing homes have moderate to severe pain, could dental causes be an under reported contributory factor. The evidence suggests that this is an under-researched area. Our project aims were to explore and consolidate the current literature and conduct some stakeholder groups with care home managers and dentists. Our stakeholder group will be reported elsewhere. Methods: We used the SPIDER framework to set out key search terms. Which included “dementia” OR “cognitively-impaired” OR “carehome residents” AND “dental pain” OR “oralfacial pain” OR “mouth pain” AND “pain assessment” OR “pain identification”. A literature search was carried out on 8 and 9 March 2022 in the electronic databases: Cochrane, PubMed, Medline, Dental & Oral Sciences Source, CINAHL, Global Health, SocINDEX, Ovid (Medline) and Scopus. Restrictions were placed on dates and language (2012–2022 and English only). Results: The search yielded 775 papers up to the year 2020. After screening and exclusion, we were left with five papers: four quantitative and one qualitative. Conclusions: This review demonstrates that there has been very little research into oral health and/or dental pain in adults with dementia. Furthermore, the recommendations have yet to be taken forward. Identifying pain in older adults with dementia remains challenging. There is a need to develop an algorithm in conjunction with care home staff and dental practitioners in order to identify and address the pain associated with dental disease in adults with dementia.

Measurement properties, interpretability and feasibility of instruments measuring oral health and orofacial pain in dependent adults: a systematic review

Background

Dependent adults have been shown to have a greater experience of oral health deterioration and orofacial pain. This is partly because their non-dental caregivers may not easily identify oral health problems and orofacial pain experienced by them. Thus, this systematic review aimed to investigate measurement properties, interpretability and feasibility of instruments assessing oral health and orofacial pain in dependent adults, which can be used by the non-dental caregivers to establish oral care plans for those who are dependent upon them.

Methods

Seven bibliographic databases were searched: MEDLINE, Embase, CINAHL, CENTRAL, HTA, OATD and OpenGrey. Citations and reference lists of the included studies were also manually searched. Two authors independently screened titles and abstracts, and then full texts. A quality assessment of included studies was conducted independently by two authors using the COSMIN Risk of Bias checklist. The best evidence synthesis method was used to synthesise results from different studies for each measurement property per measurement instrument by integrating the overall rating for each measurement property per measurement instrument with its quality level of evidence.

Results

Nineteen eligible studies were included, which reported the development, measurement properties’ evaluation, interpretability and feasibility of nine oral health and three orofacial pain measurement instruments. Methodological quality of the included studies ranged from very good to inadequate. None of the identified measurement instruments has been adequately and comprehensively tested.

Conclusions

While several measurement instruments were identified in this systematic review, more evidence is needed to be able to more comprehensively evaluate these instruments. Among those identified, the OPS-NVI demonstrated sufficient construct validity, while the OHAT and the THROAT demonstrated sufficient reliability. These instruments therefore have potential for future use with more confidence once other measurement properties, interpretability and feasibility have been sufficiently tested and evaluated.

Faces of Pain during Dental Procedures: Reliability of Scoring Facial Expressions in Print Art

BACKGROUND

Observational tools have been developed to assess pain in cognitively impaired individuals. It is not known, however, whether these tools are universal enough so that even pain depicted in print art can be assessed reliably. Therefore, the aim of this study was to assess the reliability in scoring facial expressions of pain in dental print art from the 17th, 18th, and 19th century, using a Short Form of the 15-item Pain Assessment in Impaired Cognition (PAIC15-SF) tool.

METHODS

Seventeen prints of patients undergoing dental procedures were scored twice by two inexperienced observers and an expert and once by a Gold Standard observer.

RESULTS

All observers achieved high intra-observer reliability for all four items of the category "facial expressions" and for three items of the category "body movements" (ICC: 0.748-0.991). The remaining two items of the category "body movements", viz., "rubbing" and "restlessness", were excluded from further research because it was not possible to calculate a reliable ICC. Overall, the intra-observer reliability of the expert was higher than that of the inexperienced observers. The inter-observer reliability scores varied from poor to excellent (ICC: 0.000-0.970). In comparison to the Gold Standard, the inter-observer reliability of the expert was higher than that of the inexperienced observers.

CONCLUSION

The PAIC15-SF tool is universal enough even to allow reliable assessment of facial expressions of pain depicted in dental print art.

Oral Health Assessment Tool (OHAT) deputized to informal caregivers: Go or no go?

OBJECTIVE

Investigating the usability of the Dutch version of the Oral Health Assessment Tool (OHAT-NL) with informal caregivers of community-dwelling older people with suspected dementia, without specific training.

MATERIALS AND METHODS

In accordance with guidelines for establishing the cultural equivalency of instruments, the OHAT was translated into Dutch. Fifteen informal caregivers of community-dwelling older people with suspected dementia and, as a reference standard, a dentist assessed the oral health of the older people using the OHAT-NL. The caregivers' scores were compared with the dentist's scores. The usability of the OHAT-NL was rated on a 10-point scale (0 = incomprehensible, and 10 = very user friendly) and investigated further through short structured interviews.

RESULTS

There were differences between the dentist's and caregivers' assessments of the individual categories of the OHAT-NL. The specificity of the need to visit an oral health care professional was 100.0%, while the sensitivity was 78.6%. The informal caregivers concluded that the tool made them more aware of different aspects of oral health. The tool was rated with a mean score of 7.7 (SD 1.7).

CONCLUSION

The OHAT-NL could be a useful tool for informal caregivers without specific training to indicate whether the person they care for should visit an oral health care professional.

Assessment of oral health in older adults by non-dental professional caregivers-development and validation of a photograph-supported oral health-related section for the interRAI suite of instruments

OBJECTIVES

An optimized oral health-related section and a video training were developed and validated for the interRAI suite of instruments. The latter is completed by professional non-dental caregivers and used in more than 40 countries to assess care needs of older adults.

METHODS

The optimized oral health-related section (ohr-interRAI) consists of nine items and a video training that were developed in consecutive phases. To evaluate psychometric properties, a study was conducted in 260 long-term care residents. Each resident was assessed by a dentist and by four caregivers (two who received the video training, two who did not).

RESULTS

Mean kappa values and percent agreement between caregivers and dentist ranged between κ = 0.60 (80.2%) for dry mouth and κ = 0.13 (54.0%) for oral hygiene. The highest inter-caregiver agreement was found for dry mouth with κ = 0.63 [95% CI: 0.56-0.70] (81.6%), while for the item palate/lips/cheeks only κ = 0.27 [95% CI: 0.18-0.36] (76.7%) was achieved. Intra-caregiver agreement ranged between κ = 0.93 [95% CI: 0.79-1.00] (96.4%) for dry mouth and κ = 0.45 [95% CI: 0.06-0.84] (82.8%) for gums. Logistic regression analysis showed only small differences between caregivers who watched the video training and those who did not.

CONCLUSIONS

Psychometric properties of the optimized ohr-interRAI section were improved compared to previous versions. Nevertheless, particularly the items based on inspection of the mouth require further refinement and caregiver training needs to be improved.

CLINICAL RELEVANCE

Valid assessment of oral health by professional caregivers is essential due to the impaired accessibility of regular dental care for care-dependent older adults.

The Impact of Dementia on Oral Health and Dental Care, Part 1: Setting the Scene for Dental Care Provision

There are over 850,000 people living with dementia in the UK and this figure is expected to rise to over a million by 2021. Increasingly, oral healthcare professionals in primary care will see more patients affected by dementia at varying stages of the disease, and it is therefore crucial that they have a basic understanding of the disease and how these patients can be managed in a primary care environment. The first article in this series of two provides a definition of dementia and describes the symptoms of the disease along with the key issues related to oral health, such as oral pain. Oral pain can have far reaching consequences, but identifying it can be problematic, particularly in the latter stages of the disease. This article will therefore cover how to diagnose pain in patients with dementia. Information is also provided about how to make dental surgeries more 'dementia friendly'.

Prevalence and associations of orofacial pain and oral health factors in nursing home residents with and without dementia

OBJECTIVES

determine and compare the prevalence of orofacial pain in older nursing home residents with and without dementia and explore the association between orofacial pain and health factors.

METHODS

cross-sectional study conducted in four UK nursing homes. We used the Orofacial-Pain Scale for Non-Verbal Individuals (OPS-NVI) to identify orofacial pain in residents with dementia. Residents who were able to communicate self-reported orofacial pain. A brief oral examination was conducted. Information on demographics, Clinical Dementia Rating, Charlson Comorbidity Index, Cohen Mansfield Agitation Inventory, Barthel Index, 5-level Euroqol 5 Dimension, Oral Health Impact Profile 14, Mini Nutritional Assessment Short Form and medication was collected. Chi-squared tests, independent sample t-tests and Mann-Whitney U-tests were used to compare outcomes between groups. Multivariable logistic regression was used to evaluate predictors of orofacial pain.

RESULTS

orofacial pain, assessed with the OPS-NVI, was present in 48.8% (95% confidence interval [C.I.] 36.1-50.7) of residents with dementia. Self-reported orofacial pain was present in 37.8% (95% C.I. 20.4-53.7) of residents with dementia and in 14.8% (95% C.I. 0.5-30.4) residents without dementia. Orofacial pain was significantly more prevalent in residents with dementia than those without (OPS-NVI; P = 0.002, self-report; P = 0.04). Having a soft diet, xerostomia, being dentate, and poor oral hygiene in dentate residents were significant predictors of orofacial pain in residents with dementia.

CONCLUSION

orofacial pain was more prevalent in residents with dementia. Oral health care should be part of routine care for residents, especially for those with dementia, to improve oral health and decrease the risk of developing orofacial pain.

Orofacial pain and its potential oral causes in older people with mild cognitive impairment or dementia

Background

The number of people with dementia and natural dentition is growing. As dementia progresses, the degree of self‐care decreases and the risk of oral health problems and orofacial pain increases.

Objectives

To examine and compare the presence of orofacial pain and its potential causes in older people with Mild Cognitive Impairment (MCI) or dementia.

Methods

In this cross‐sectional observational study, the presence of orofacial pain and its potential causes was studied in 348 participants with MCI or dementia with all levels of cognitive impairment in two outpatient memory clinics and ten nursing homes.

Results

Orofacial pain was reported by 25.7% of the 179 participants who were considered to present a reliable pain self‐report (Mini‐Mental State Examination score ≥14 points), while it could not be determined in people with more severe cognitive impairment. The oral health examination of the 348 participants indicated that potential painful conditions, such as coronal caries, root caries, tooth root remnants or ulcers were present in 50.3%. There was a significant correlation between the level of cognitive impairment and the number of teeth, r = 0.185, P = 0.003, teeth with coronal caries, r = −0.238, P < 0.001, and the number of tooth root remnants, r = −0.229, P = 0.004, after adjusting for age.

Conclusions

This study indicated that orofacial pain and its potential causes were frequently present in participants with MCI or dementia. Therefore, a regular oral examination by (oral) healthcare providers in people with MCI or dementia remains imperative, even if no pain is reported.
