Strategies to integrate oral health into primary care: a systematic review

Abstract

ObjectivesIntegration of oral health into primary care has been proposed as a primary healthcare approach for efficient and sustainable delivery of oral health services, and the effective management of oral diseases. This paper aimed to synthesise evidence on the effectiveness of strategies to integrate oral health into primary care.DesignSystematic review.Data sourcesMEDLINE, CINAHL, Embase, Scopus, ProQuest, Cochrane and Google Scholar were searched without date limits until the third week of June 2022. Reference lists of eligible studies were also searched. Experts in the field and existing professional networks were consulted.Eligibility criteriaOnly studies that evaluated integration strategies were included in the review. Eligibility was restricted to English language studies published in academic peer-reviewed journals.Data extraction and synthesisTwo reviewers independently extracted data and performed the risk of bias assessments. A narrative synthesis approach was used to report review findings. Heterogeneity among included studies precluded a meta-analysis.ResultsThe search identified 8731 unique articles, of which 49 were included in the review. Majority of the studies explored provision of oral healthcare by primary care professionals in primary care settings, where integration was primarily via training/education and/or policy changes. Most studies reported results favouring the integration strategy, such as improvements in referral pathways, documentation processes, operating efficiencies, number of available health staff, number of visits to non-dental primary care professionals for oral health issues, proportion of children receiving fluoride varnish applications/other preventive treatment, proportion of visits to an oral health professional and dental caries estimates.ConclusionThe findings from this review demonstrate that the majority of identified strategies were associated with improved outcomes and can be used to inform decision-making on strategy selection. However, more research and evaluation are required to identify best practice models of service integration.PROSPERO registration numberCRD42020203111.

Oral health system strengthening in fragile and conflict-affected states: A systematic review

“…The review also stresses the necessity for adaptability in oral health care services, showcasing the potential of various platforms, including mobile services, where health care is brought directly to the public, and the use of innovative technologies to enhance access even in challenging circumstances. Integrated care is recognised as a vital strategy for enhancing access and optimising resource utilisation, with the integration of oral health into primary health care services being an ongoing subject of discussion [ 75 – 77 ]. Whilst the evidence supporting integration is limited, this review showcases instances where oral health initiatives were presented either as independent programmes or integrated into broader health care services, either from their inception or as an addition to existing initiatives.…”

Influence of School Type and Class Level on Mean Caries Experience in 12-Year-Olds in Serial Cross-Sectional National Oral Health Survey in Germany—Proposal to Adjust for Selection Bias

“…These strategies to promote oral health are important, especially for children who are difficult to reach outside of the school in contrast to children and adolescents who regularly attend dental visits including individual caries prophylaxis anyway [31]. Moreso, valid caries data are important for the assessment of the efficacy of integrating oral health preventive measures [32,33].…”

Consenting on essential oral health care benefit basket

“…In addition, a framework on how to define an essential benefits basket is still lacking (Jashni et al, 2023). A systematic review found that having an OH benefits package is a precondition to integrate OH into primary care (Christian et al, 2023), but it does not specify how to set or define this package. The WHO defined a "basic package for OH" two decades ago (2002), focusing on low-income countries (Frencken et al, 2003).…”
