Impaired oral health associations with cognitive and motor decline in activities of daily living independence during hospitalization: insights from a post-stroke cohort

PURPOSE

Evidence is scarce on the associations between impaired oral health and cognitive level related to independence in activities of daily living (ADLs) among hospitalized older patients. We aimed to evaluate the associations between baseline oral problems and changes in cognitive level in post-stroke patients.

METHODS

A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients. Revised Oral Assessment Guide (ROAG) as a measure of oral health and function was assessed at admission. Primary outcomes included discharge scores for cognitive function assessed by the cognitive domain of the Functional Independence Measure (FIM-cognition) and the corresponding change in FIM-cognition during hospitalization. Another outcome measure was the motor domain of FIM (FIM-motor). Multivariate linear regression analyses were employed to assess the association between baseline ROAG and the designated outcomes, adjusting for potential confounding factors.

RESULTS

Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median ROAG was 10 [9, 12], with 811 patients (84.9%) presenting oral problems. After fully adjusting for confounding factors, the ROAG was significantly and negatively associated with FIM-cognition at discharge (β = -0.107, p = 0.031) and FIM-cognition gain (β = -0.093, p = 0.018). Further, the ROAG was independently and negatively associated with FIM-motor at discharge (β = -0.043, p = 0.013) and FIM-motor gain (β = -0.065, p = 0.013).

CONCLUSION

Oral problems were associated with compromised cognitive levels and a decline in physical function during the hospitalization in post-stroke patients. These results underscore the critical importance of addressing oral health in this patient population.

Coexistence of low body mass index and poor oral health negatively affects activities of daily living, swallowing, and cognition after stroke

AIM

Low body mass index (BMI) and poor oral health are prevalent among older stroke patients and associated with adverse outcomes. However, their combined impact on functional recovery after stroke remains unclear. This study investigated the synergistic effects of low BMI and poor oral health on activities of daily living (ADL) independence, swallowing function, and cognitive status in post-stroke older patients.

METHODS

A retrospective cohort study was conducted on 708 hospitalized post-stroke patients aged ≥70 years. Low BMI was defined as <20 kg/m2, and poor oral health was assessed using the Revised Oral Assessment Guide (ROAG) with a score ≥13 indicating oral problems. The primary outcome was ADL independence (Functional Independence Measure-motor score >78) at discharge. Secondary outcomes included swallowing level (Food Intake Level Scale) and cognitive status (Functional Independence Measure-cognition score). Multiple regression analyses were performed to examine the associations of low BMI, poor oral health, and their combination with outcomes of interest.

RESULTS

The coexistence of low BMI and poor oral health was independently associated with lower odds of achieving ADL independence (odds ratio 0.130, 95% confidence interval [CI] 0.023-0.718), worse swallowing level (B = -0.878, 95% CI -1.280 to -0.476), and poorer cognitive status (B = -1.872, 95% CI -2.960 to -0.784) at discharge, after adjusting for confounders. The combined impact was stronger than either condition alone.

CONCLUSIONS

The coexistence of low BMI and poor oral health exerts a synergistic negative impact on functional recovery in older stroke inpatients. Comprehensive interventions integrating nutritional support, oral management, and rehabilitation are crucial to optimizing outcomes in this vulnerable population.

A preventive care approach for oral health in nursing homes: a qualitative study of healthcare workers' experiences

BACKGROUND

Oral health problems are common among care-dependent older adults living in nursing homes. Developing strategies to prevent the deterioration of oral health is therefore crucial to avoid pain and tooth loss. A standardized work widely used in nursing homes in Sweden is the quality register Senior Alert (SA), which assesses age-related risks concerning e.g. pressure sores, falls, malnutrition and oral health. The oral health assessment is performed with the Revised Oral Assessment Guide-Jönköping (ROAG-J), which also includes planning and implementation of preventive oral care interventions with the goal of achieving good quality care. However, what facilitates and hinders healthcare workers in working with oral health in SA remains unexplored. The aim of this study was to describe healthcare workers' experiences of assessing oral health with the ROAG-J, planning and performing preventive oral health care actions in accordance with SA in nursing homes.

METHODS

Healthcare workers (n = 28) in nursing homes in two Swedish municipalities participated and data was collected through six focus group interviews. Reflexive thematic analysis was used to identify patterns of meaning in the data.

RESULTS

Themes generated in the analysis were: (1) A structured process promotes communication and awareness and stresses the importance of oral health; (2) Oral care for frail older adults is challenging and triggers ethical dilemmas; (3) Unclear responsibilities, roles and routines in the organization put oral health at risk; (4) Differences in experience and competence among healthcare staff call for educational efforts.

CONCLUSIONS

The structured way of working increases staff awareness and prioritization of oral health in nursing homes. The main challenges for the healthcare workers were residents' reluctance to participate in oral care activities and oral care being more complicated since most older adults today are dentate. Organizational challenges lay in creating good routines and clarifying staff roles and responsibilities, which will require continuous staff training and increased management involvement.

Dual burden of sarcopenia and impaired oral status on activities of daily living, cognition and swallowing outcomes in post-stroke patients

BACKGROUND AND AIMS

Sarcopenia and poor oral health are common in older patients and are associated with negative outcomes. However, evidence of their combined impact on post-stroke rehabilitation outcomes is limited. This study aimed to investigate the combined impact of sarcopenia and impaired oral health on activities of daily living (ADL), cognition, and swallowing outcomes in post-stroke patients.

METHODS

A retrospective cohort study was conducted using 1,012 post-stroke patients (median age 75.6 years; 54.1 % men). Sarcopenia was diagnosed using the Asian Working Group for Sarcopenia 2019 criteria. Poor oral health was assessed using the Revised Oral Assessment Guide (ROAG) with a score ≥13 indicating impaired oral status. Functional outcomes were measured using the Functional Independence Measure (FIM) for ADL and cognition, and the Food Intake Level Scale (FILS) for swallowing status.

RESULTS

The prevalence of sarcopenia was 45.6 % (492/1,080), impaired oral health was 27.5 % (297/1,080), and the coexistence of both conditions was 12.0 % (130/1,080). The coexistence of sarcopenia and impaired oral health was associated with poorer outcomes compared to either condition alone. After adjusting for confounders, the combination of sarcopenia and impaired oral status showed the strongest negative impact on FIM-motor (B=-8.666, 95 % CI -11.484 to -5.847), FIM-cognition (B=-1.122, 95 % CI -1.987 to -0.256), and FILS (B=-0.785, 95 % CI -1.055 to -0.514) scores at discharge.

CONCLUSION

The dual burden of sarcopenia and impaired oral health significantly impacts functional recovery in post-stroke patients. Comprehensive assessments and interventions targeting both conditions may optimize rehabilitation outcomes in this population.

Effective Oral Indicators With Medical and Dental Collaboration in Open Heart Surgery: A Representative Survey

Purpose Postoperative infections pose an important problem for patients with cardiac disease. Moreover, oral health status is associated with the risk of longer hospital stays. Therefore, the oral health status of patients was assessed before open-heart surgery. This study aimed to determine the relationship between oral health status and postoperative status. Methods The study included 25 patients who underwent open-heart surgery at our university hospital in 2020. Upon admission, dentists conducted an oral examination and assessed the oral health status of the patients, also using the Japanese version of the Oral Health Assessment Tool (OHAT-J), Revised Oral Assessment Guide (ROAG), oral moisture level, oral bacteria, and other relevant factors. The study investigated the association with postoperative status. Findings Significant postoperative infections were found in patients aged ≥70 years, with an OHAT-J score of ≥5, OHAT-J lip score of ≥1, Streptococcus γ count of 1.0 × 10^6 or higher (CFU/mL), and increased Streptococcus γ before and after surgery. The duration of hospitalization correlated with the OHAT-J, OHAT-J gum and tissue, and ROAG scores. The duration of intensive care unit (ICU) stays correlated with the OHAT-J score. Conclusions The study demonstrates that OHAT-J scores are linked with predicting not just postoperative infection but also the length of hospitalization and ICU stay. As OHAT-J scores do not necessitate specialized dental instruments, they are straightforward and beneficial for healthcare professionals outside of dentistry.

Impaired oral status is associated with sarcopenic obesity in post-stroke patients

PURPOSE

Oral problems and muscle health are indeed significant concerns in ageing populations. However, there is limited evidence concerning the association between these issues. The study's focus was to investigate the association between oral problems and sarcopenic obesity, wherein sarcopenia and obesity coexist concurrently, in post-stroke patients.

METHODS

This retrospective, observational, cross-sectional study included patients hospitalised for post-stroke rehabilitation. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). Sarcopenic obesity was diagnosed according to the European Society of Clinical Nutrition and Metabolism/European Association for the Study of Obesity criteria. Multiple linear regression analysis was used to examine the association between the ROAG and sarcopenic obesity after adjusting for confounding factors.

RESULTS

A total of 760 patients were included, with a mean (SD) age of 71 (9) years, of whom 408 (54.7%) were male. The median (interquartile range, 25th and 75th percentiles) ROAG was 11 [9, 13]. Sarcopenic obesity was diagnosed in 16 (3.9%) men, 18 (5.1%) women, and 34 (4.5%) patients overall. Multivariate linear analysis showed that ROAG was significantly and positively associated with sarcopenic obesity (β = .091, P = .023), followed by obesity alone (β = .084, P = .044), and sarcopenia alone (β = .081, P = .037).

CONCLUSION

Oral problems were associated with sarcopenic obesity in post-stroke. Oral assessment and intervention may have a positive impact on ADL and QOL in post-stroke patients with sarcopenic obesity.

The association between oral health status and physical function in elderly patients with acute heart failure

OBJECTIVES

Oral health problems are common and are associated with various geriatric conditions in older adults. The importance of oral health has not been fully highlighted in the assessment and management of patients with heart failure. Here, we investigated the association between oral health status and the decline in physical function during hospitalization in elderly patients with acute heart failure.

MATERIALS AND METHODS

We evaluated oral health using the revised oral assessment guide in 77 patients aged 65 years or older who were admitted to hospital for acute heart failure. Oral health problems were defined as a revised oral assessment guide score ≥9.

RESULTS

Oral health problems were identified in 66.2% of the patients. Patients with oral health problems had high prevalence of decreased physical function, undernutrition, and cognitive impairment. A reduction in the Barthel Index, as an indicator of activities of daily living during hospitalization, was significant in the enrolled patients. The Barthel Index decreased more in patients with oral health problems than those with normal oral health. Furthermore, the revised oral assessment guide score on admission was found to be the only independent predictor of changes in the Barthel Index during hospitalization in the multivariate analyses.

CONCLUSIONS

Oral assessment using the revised oral assessment guide during hospitalization could provide useful information for the management of elderly heart failure patients.

Association of poor oral health status and faecal incontinence in patients with dysphagia: A cross-sectional analysis from the Sarcopenic Dysphagia Database

BACKGROUND

Poor oral health status may alter oral and gut microbiota. Previous studies have shown that poor oral health can exacerbate gut inflammation. Therefore, poor oral health status may be related to faecal incontinence via changes in the gut.

OBJECTIVE

To investigate the association between poor oral health status and faecal incontinence in inpatients with dysphagia.

METHODS

This multicentre cross-sectional study included 423 patients (mean age 79.8 ± 11.5 years, 48.2% female) with dysphagia. Oral health status was assessed at each facility using the Oral Health Assessment Tool (OHAT) or the Revised Oral Assessment Guide (ROAG). Poor oral health status was defined as an OHAT score of ≥3 or a ROAG score of ≥13. A multivariate logistic model was used to analyse the association between poor oral health status and faecal incontinence.

RESULTS

A total of 351 (83.0%) patients had poor oral health and 97 (22.7%) had faecal incontinence. Patients with poor oral health status had a higher proportion of faecal incontinence than those with normal oral health status (25.4% vs. 11.1%, p = .009). A multivariate logistic model revealed an association between faecal incontinence and poor oral health status (adjusted odds ratio = 2.501, 95% confidence interval = 1.065-5.873, p = .035).

CONCLUSIONS

Poor oral health status assessed by OHAT or ROAG in inpatients with dysphagia may adversely affect faecal incontinence. Further studies are needed to determine the causal relationship between poor oral health status and faecal incontinence.

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.

Improvement in Oral Health Enhances the Recovery of Activities of Daily Living and Dysphagia after Stroke

OBJECTIVE

Oral problems affect rehabilitation outcomes. This study aimed to examine the association between improvement in oral health and functional outcomes in patients after stroke.

MATERIALS AND METHODS

This retrospective cohort study included post-acute rehabilitation patients who presented with oral problems at admission. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). The ROAG score change during hospitalization was calculated by subtracting the score at admission from the score at discharge; oral problems were defined as "improved", when the score change value was lower than the median value. Study outcomes were the activities of daily living assessed by the motor domain of the Functional Independence Measure (FIM-motor) scores and dysphagia as assessed by the Food Intake Level Scale (FILS). Multivariate regression analyses were used to determine whether improved oral problems were associated with study outcomes. P-values of <0.05 were considered statistically significant.

RESULTS

This study included 300 patients (mean age, 72.0 years; 51.7% men). The median [IQR] baseline ROAG score and its change value during hospitalization were 11 [10, 14] and -1[-3, 0] points, respectively. Multivariate analyses showed that improved oral problems was independently associated with FIM-motor score (β = 0.144, p = 0.001) and FILS score (β = 0.227, p < 0.001) at discharge, after adjusting for potential confounders.

CONCLUSIONS

Improvement in oral health was positively associated with recovery of the ADL and dysphagia after stroke. Early detection of oral problems and oral treatment should be implemented in these patients to maximize functional recovery.

Oral health among older adults in nursing homes: A survey in a national quality register, the Senior Alert

Aim

To investigate the extent to which the Revised Oral Assessment Guide–Jönköping (ROAG‐J) is used by nursing staff routinely in nursing homes in Sweden and to describe oral health status of the residents.

Design

An observational, retrospective register‐based study.

Methods

Data from different validated health assessments instruments, including ROAG‐J, for the period 2011–2016 were obtained from the Web‐based national quality register Senior Alert. The basis for the analyses was 190,016 assessments.

Results

About half of all residents had underwent at least one annual ROAG‐J assessment (2014–2016). During the period 2011–2016, 42% of the residents (n = 92,827) were registered to have oral health problems. Significantly more oral health problems were found for men and for those with younger age, poorer physical condition, neurophysiological problems, underweight, impaired mobility and many medications. In conclusion, poorer oral health was found for more care‐dependent individuals, which shows a need of preventive actions.

Association of impaired oral health status with chronic kidney disease in post-acute rehabilitation

BACKGROUND

Despite the growing interest in oral health and chronic disease in geriatric medicine, the evidence of an association between the two variables is limited.

OBJECTIVES

This study sought to examine the association between oral health status and chronic kidney disease (CKD) in this setting.

MATERIALS AND METHODS

This retrospective study included consecutive post-acute patients in a rehabilitation hospital. Oral health status was evaluated using the Revised Oral Assessment Guide (ROAG). Renal function or CKD stage was assessed by measurement of the estimated glomerular filtration rate (eGFR). Multivariate logistic regression analysis was used to determine which subcategories of ROAG were independently associated with advanced CKD stages (vs. early CKD stages). Multiple linear regression analysis was used to clarify whether eGFR on admission was independently associated with ROAG score after adjusting for potential confounders.

RESULTS

A total of 1056 (mean age 70 years; 52% women) were included in the analysis. Slight and moderate-to-severe oral health problems were detected in 57.7% and 15.4% of patients, respectively. Patients with oral problems had a more severe stage of CKD (P = .036) and a lower eGFR (P = .028). Among subitems of ROAG, tongue (OR = 1.40, P = .041), saliva (OR = 1.72, P = .039) and oral cavity mucosa (OR = 1.37, P = .013) status was independently associated with the presence of CKD stages 3, 4 and 5. Furthermore, eGFR was independently associated with ROAG score (β = -0.180, P = .034) after adjusting for possible confounders.

CONCLUSIONS

Impaired oral health status is common and closely associated with CKD in post-acute inpatients.

Intersegmenter Variability in High-Speed Laryngoscopy-Based Glottal Area Waveform Measures

OBJECTIVES/HYPOTHESIS

High-speed videoendoscopy (HSV) has potential to objectively quantify vibratory vocal fold characteristics during phonation. Glottal Analysis Tools (GAT) version 2018, developed in Erlangen, Germany, is software for determining various glottal area waveform (GAW) quantities. Before having GAT analyze HSV videos, segmenters have to define glottis manually across videos in a semiautomatic segmentation protocol. Such interventions are hypothesized to induce variability of subsequent GAW measure computation across segmenters and may attenuate GAT measures' reliability to a certain point. This study explored intersegmenter variability in GAT's GAW measures based on semiautomatic image processing.

STUDY DESIGN

Cohort study of rater reliability.

METHODS

In total, 20 HSV videos from normophonic and dysphonic subjects with various laryngeal disorders were selected for this study and segmented by three trained segmenters. They separately segmented glottis areas in the same frame sets of the videos. Upon analysis of GAW, GAT offers 46 measures related to topologic GAW dynamic characteristics, GAW periodicity and perturbation characteristics, and GAW harmonic components. To address GAT's reliability, intersegmenter-based variability in these measures was examined with intraclass correlation coefficient (ICC).

RESULTS

In general, ICC behavior of the 46 GAW measures across three raters was highly acceptable. ICC of one parameter was moderate (0.5 < ICC < 0.75), good for seven parameters (0.75 < ICC < 0.9), and excellent for 38 parameters (0.9 < ICC).

CONCLUSIONS

Overall, high ICC values confirm clinical applicability of GAT for objective and quantitative assessment of HSV. Small intersegmenter differences with actual small parameter differences suggest that manual or semiautomatic segmentation in GAT does not noticeably influence clinical assessment outcome. To guarantee the software's performance, we suggest segmentation training before clinical application.
