Randomised clinical trial of a motivational interviewing intervention to improve oral health education amongst older adults in Philadelphia: 12‐month evaluation of non‐clinical outcomes

Abstract

ObjectivesWe conducted a trial to assess the treatment fidelity of an individual‐based oral health education intervention utilising motivational interviewing (MI) techniques and its efficacy when compared to a group‐based traditional oral health education intervention (TOHE) and a standard of care group (SC) in a sample from Philadelphia during a 12‐month follow‐up.BackgroundThere is lack of information on how different types of oral health educational interventions affect older adults on non‐clinical outcomes including changes in oral health‐related quality of life (OHRQoL), oral health self‐efficacy (SE) and oral health knowledge (OHK).Materials and methodsOne hundred and eighty patients were randomly allocated to TOHE, MI and SC groups. Treatment fidelity was measured in 16 non‐study patients. The MI intervention was administered by a public health dental hygienist (PHDH). All interviews were audio‐recorded and coded by an expert using the Motivational Interviewing Treatment Integrity (MITI) Code. Multivariable longitudinal regression analyses accounting for baseline demographics and correlated errors due to repeated measures via generalised estimating equation were conducted following an intention to treat approach.ResultsOver the 1‐year follow‐up, SE and OHRQoL scores significantly improved amongst the MI group whereas both outcomes worsened amongst the SC group. During the same period, SE and OHRQoL did not change in the TOHE group.ConclusionFindings from the study support the fidelity of this intervention and the improvement of all non‐clinical outcomes after 12 months amongst the MI group.

The effect of clinical interventions on the oral health‐related quality of life in older adults

“…Further, a study incorporating a MI intervention had demonstrated significant improvements in the outcome measure compared to both group education and standard care frameworks. 18 The methodological quality for the included studies varied (Fig. 2).…”

Reducing Time to Discharge after Chemotherapy by Standardizing Workflow and Providing Outpatient Intravenous Hydration

“…Due to time and resource limitations, the team decided not to explore causes and interventions for patients who were uncomfortable with outpatient hydration. Several tools and interventions to help understand and improve patients’ comfort level with self-management include shared decision-making models, 20 , 21 motivational interviewing, 22 , 23 face-to-face support, 24 and supervised practice. 25 Some of these interventions could be tested and explored in future quality improvement projects.…”

A feasibility and acceptability study of using an intra-oral camera and an asynchronous tele-mentoring protocol to detect and identify oral lesions

“…Strategies to decrease the incidence and mortality of oral and oropharyngeal cancers include evidence-based prevention strategies such as motivational interviewing (MI) to improve oral health education 4 and HPV vaccination to prevent infections and cancers of oropharynx, tonsils, and base of the tongue in both women and men. 5 – 7 Visual and tactile screening by dentists at chairside during routine examinations for the discovery of pre- and cancerous lesions or other conditions that may benefit from treatment or close follow-up is also recommended.…”
