Orofacial dysfunction after stroke-A multidisciplinary approach

OBJECTIVE

This paper describes the study protocol in an ongoing clinical trial evaluating oral screen training as part of a post-stroke rehabilitation programme. Baseline data were related to four domains: dysphagia, lip function, masticatory performance and patient-related outcome measures (PROM).

BACKGROUND

Stroke is one of the most common causes of disability-adjusted life years, and dysphagia is a common remaining problem after stroke. Rehabilitation using oral screen training has been suggested to improve swallowing, but evidence is still insufficient.

MATERIALS AND METHODS

Patients diagnosed with stroke with persisting objective and/or subjective swallowing dysfunction after primary rehabilitation were assessed for eligibility. In total, 25 patients were included. Objective function was assessed by swallowing capacity test (SCT), lip force and masticatory performance, subjective function by EAT-10 and NOT-S and PROM by LiSat-11 and ESAS.

RESULTS

Baseline data presented a heterogeneous pattern with no significant association between objective and subjective dysfunction. Most of the participants (20/25) showed impaired swallowing capacity in SCT, and 23/24 revealed orofacial dysfunction according to NOT-S. The most common subjective item reported was chewing and swallowing problems (19/24).

CONCLUSION

The heterogenous findings in the included tests and the lack of correlations emphasise the importance of multidisciplinary approaches to identify objective and subjective orofacial post-stroke dysfunction in clinical practice to be able to offer evidence-based individualised care. The included participants were representative of stroke patients with dysphagia, which supports proceeding with the planned intervention.

Are we passing the acceptable? Standard setting of theoretical proficiency tests for foreign-trained dentists

INTRODUCTION

Dentists educated outside the EU, EEA and Switzerland have the option to undergo proficiency testing to practice dentistry in Sweden. A standardised evidence-based procedure for proficiency tests is crucial. This paper explores if the standard setting of the theoretical examination in the Swedish proficiency test for foreign dentists is fit to differentiate candidates who meet the acceptable standard for licensure from those who do not, by analysis of inter-rater reliability and credibility of Angoff panels and the test's ability to differentiate candidates regarding learning outcomes and dental disciplines.

MATERIALS AND METHODS

In a cohort study design, test results were collected from seven examinations during 2018-2019 (n = 316), combined with Angoff judgements and demographic data from The National Board of Health and Welfare. Intraclass correlation, Pearson correlation and linear regression were calculated.

RESULTS

All exams demonstrated substantial judge inter-rater reliability using the Angoff procedure (0.65-0.82). Item difficulty predicted by the expert panels showed significant positive correlations with the item difficulty by candidate results (0.69-0.77). Candidates who did not meet the requirements for pass mark in the theoretical test revealed a significantly reduced performance overall in professional qualifications (i.e., learning outcomes) and reduced performance within dental disciplines.

CONCLUSIONS

The results indicate that a modified Angoff method is a feasible, simple, and defensible method for setting the pass mark for the theoretical examinations. The standard setting appears to differentiate candidates who do not meet the requirements of the professional qualifications of the dental degree. Adjustments could be undertaken to further discriminate for competence within single dental disciplines.

Effects of Domiciliary Professional Oral Care for Care-Dependent Elderly in Nursing Homes - Oral Hygiene, Gingival Bleeding, Root Caries and Nursing Staff's Oral Health Knowledge and Attitudes

Purpose

The primary aim was to describe the effects for nursing home residents of monthly professional cleaning and individual oral hygiene instruction provided by registered dental hygienists (RDHs), in comparison with daily oral care as usual. The secondary aim was to study the knowledge and attitudes among nursing staff regarding oral health care and needs.

Patients and Methods

In this randomised controlled trial (RCT), 146 residents were recruited from nine nursing homes in Regions of Stockholm and Sörmland and were randomly assigned (on nursing home level) to either intervention group (I; n=72) or control group (C; n=74). Group I received monthly professional cleaning, individual oral hygiene instructions and information given by an RDH. Group C proceeded with daily oral care as usual (self-performed or nursing staff-assisted). Oral health-related data was registered with the mucosal-plaque score index (MPS), the modified sulcus bleeding index (MSB), and root caries. The nursing staff’s attitudes and knowledge were analysed at baseline and at six-month follow-up. Statistical analysis was performed by Fisher’s exact test and two-way variance analysis (ANOVA).

Results

Improvements were seen in both Group I and Group C concerning MPS, MSB and active root caries. The nursing staff working with participants in Group I showed significant improvements regarding the Nursing Dental Coping Beliefs Scale (DCBS) in two of four dimensions, oral health care beliefs (p=0.0331) and external locus of control (p=0.0017) compared with those working with Group C. The knowledge-based questionnaire showed improvement (p=0.05) in Group I compared with Group C.

Conclusion

Monthly professional oral care, combined with individual oral health care instructions, seems to improve oral hygiene and may reduce root caries among nursing home residents. This may also contribute to a more positive attitude regarding oral hygiene measures among nursing home staff, as compared with daily oral care as usual.
