Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Review question
| Element | Planned (methods) | Found (results) |
|---|---|---|
| Population | No population-level exclusions: all ages, all ability types and all locations. Only English-language, peer-reviewed research studies included. | 49 studies; populations included children, pregnant women, older adults in residential/aged care, people with disabilities and general primary care patients; predominantly high-income countries (USA n=20, Australia n=10, Canada n=5, Belgium n=3). WHO region: Americas n=27, Western Pacific n=11, Europe n=9, South-East Asia n=3, Eastern Mediterranean n=0. Setting: primary care n=28, plus community, schools and aged-care facilities |
| Intervention | Any strategy or intervention to integrate oral health into primary care (policies, guidelines, frameworks, funding mechanisms and insurance schemes, interprofessional training/education, interprofessional practice, common performance indicators, and local/international networks) | Integration strategies (n=49): oral healthcare provided by non-dental primary care professionals in primary care (n=24, mainly via training/education and/or policy change); training/education of facility/nursing/midwifery staff; policy/financing changes including insurance coverage/reimbursement (n=5 policy-related); colocation of dental and medical services; interprofessional and community-health-worker collaboration; teledentistry; integrated oral health assessment tool; school-based activities |
| Comparison | Not specified (no comparator restriction; controlled and uncontrolled study designs eligible) | Varied; many included studies uncontrolled. Controlled designs: quasi-experimental/non-randomised trial n=8 and RCT n=2; uncontrolled/other: qualitative n=12, retrospective n=8, pre-post n=5, mixed-method n=5, pilot n=4, cross-sectional n=3 |
| Outcomes | Any indicator of strategy effectiveness: (A) uptake of guidelines/policies; (B) fidelity of implementation of guidelines/policies/programmes; (C) provider/clinician-related (scope of practice, improved knowledge, service-delivery efficiencies); (D) patient-related (oral health outcomes, oral health-related quality of life, oral-health knowledge/behaviours/attitudes, cost savings, increased access to care); cost-effectiveness | Access to oral healthcare (n=19); knowledge/attitudes/perceptions of staff and patients (n=16); oral disease outcomes (n=9, of which dental caries n=7); barriers and facilitators to implementation (qualitative); staff/patient experience and satisfaction. Economic/cost-effectiveness outcomes were a planned outcome but a major evidence gap (lack of studies) |
| Study designs | Any study design evaluating integration strategies (no design restriction) | Qualitative n=12, retrospective n=8, quasi-experimental/non-randomised controlled trial n=8, pre-post intervention n=5, mixed-method n=5, pilot n=4, cross-sectional n=3, RCT n=2 |
| Timing | Not specified | Not specified (varied follow-up; e.g., a 1-year follow-up was noted as too short for caries outcomes) |
Search date: No date limits, until the third week of June 2022. Databases: MEDLINE (principal), CINAHL, Embase, Scopus, ProQuest, Cochrane and Google Scholar; reference lists of eligible studies; experts in the field and existing professional networks consulted
Questions and results
Strategies to integrate oral health into primary care (e.g., training/education of non-dental primary care professionals, policy/financing and health-insurance changes, colocation of dental and medical services, interprofessional and community-health-worker collaboration, teledentistry, integrated oral health assessment tools, school-based activities) vs No integration / usual care (or pre-integration baseline; many included studies uncontrolled)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Access to oral healthcare (referral pathways, documentation processes, operating efficiencies, staffing, visits for oral health issues, uptake of fluoride varnish/other preventive treatment, and visits to an oral health professional) Most strategies to integrate oral health into primary care were associated with improved access to oral healthcare (19 studies, narrative synthesis; ungraded). Source: Abstract; Results (Figure 3 'Summary of outcomes and key findings'); Discussion · same question in other reviews | Access to oral healthcare was the primary outcome most studied (n=19). Most studies reported results favouring the integration strategy, including improvements in referral pathways, documentation processes, operating… | 19 studies | Ungraded |
Knowledge, attitudes and perceptions of staff and patients regarding oral health Integration strategies were generally associated with positive oral health knowledge, attitudes and perceptions among staff and patients (16 studies, narrative synthesis; ungraded). Source: Results (Figure 3 'Summary of outcomes and key findings'); Discussion · same question in other reviews | Knowledge/attitudes/perceptions of staff and patients was the second most studied outcome (n=16). Patient and staff perceptions on various aspects of the integration strategy were usually reported as positive.… | 16 studies | Ungraded |
Barriers and facilitators to implementation of the integration strategy (qualitative) Key barriers to implementing integration strategies were time/staff/resource constraints and lack of organisational support, while facilitators were professionals' knowledge and attitudes and supportive governance/leadership (qualitative; ungraded). Source: Results ('The most commonly studied qualitative outcomes were barriers and facilitators'); Discussion · same question in other reviews | The most commonly studied qualitative outcomes were barriers and facilitators related to the strategy implementation process. Reported barriers were time and staff constraints, resource limitations and lack of… | 15 studies | Ungraded |
Dental caries estimates Population: People receiving or providing primary care; all ages, ability types, and locations Seven studies measured change in dental caries estimates. Source: Results · same question in other reviews | 6 of 7 studies reported improved dental caries outcomes; 1 (Vichayanrat 2012) reported no change | 7 studies | Ungraded |
Oral disease outcomes, including dental caries estimates Most studies reported improved oral disease outcomes with integration strategies (8 of 9 studies improved, 1 no change; 9 studies, narrative synthesis; ungraded). Source: Results (Figure 3 'Summary of outcomes and key findings'); Discussion ('only nine studies ... reported oral disease outcomes') · same question in other reviews | Nine studies reported oral disease outcomes, seven of which measured change in dental caries estimates. Eight of the nine studies reported improved oral disease outcomes; one (Vichayanrat 2012) reported no change in… | 9 studies | Ungraded |
