Dental service patterns among private and public adult patients in Australia

Background While the majority of dental care in Australia is provided in the private sector those patients who attend for public care remain a public health focus due to their socioeconomic disadvantage. The aims of this study were to compare dental service profiles provided to patients at private and public clinics, controlling for age, sex, reason for visit and income. Methods Data were collected in 2004–06, using a three-stage, stratified clustered sample of Australians aged 15+ years, involving a computer-assisted telephone interview (CATI), oral examination and mailed questionnaire. Analysis was restricted to those who responded to the CATI. Results A total of 14,123 adults responded to the CATI (49% response) of whom 5,505 (44% of those interviewed) agreed to undergo an oral epidemiological examination. Multivariate analysis controlling for age, sex, reason for visit and income showed that persons attending public clinics had higher odds [Odds ratio, 95%CI] of extraction (1.69, 1.26–2.28), but lower odds of receiving oral prophylaxis (0.50, 0.38–0.66) and crown/bridge services (0.34, 0.13–0.91) compared to the reference category of private clinics. Conclusion Socio-economically disadvantaged persons who face barriers to accessing dental care in the private sector suffer further oral health disadvantage from a pattern of services received at public clinics that has more emphasis on extraction of teeth and less emphasis on preventive and maintenance care.David S Brennan, Liana Luzzi and Kaye F Roberts-Thomso

Factors influencing the use of public dental services: An application of the Theory of Planned Behaviour

Background There is limited evidence of the influence of psychosocial factors and health beliefs on public dental patient's patterns of service use in Australia. The research aims were to examine associations between dental attitudes and beliefs of public dental service users and dental visiting intention and behaviour using the Theory of Planned Behaviour. Methods 517 randomly selected adult public dental patients completed a questionnaire assessing dental attitudes and beliefs which was matched with electronic records for past and future dental service use. A questionnaire measured intentions, attitudes, subjective norms and perceptions of behavioural control and self-efficacy in relation to visiting public dentists. A measure of dental attendance at public dental clinics was obtained retrospectively (over 3 1/2 years) and prospectively (over a one year period following the return of the questionnaire) by accessing electronic patient clinical records. Results Participants had positive attitudes, subjective norms and self-efficacy beliefs towards dental visiting but perceived a lack of control over visiting the dentist. Attitudes, subjective norms, self-efficacy and perceived control were significant predictors of intention (P < 0.05). Intentions, self-efficacy and past dental attendance were significant predictors of actual dental attendance (P < 0.05). Conclusion Public dental patients held favourable attitudes and beliefs but perceived a lack of control towards dental visiting. Reducing structural barriers may therefore improve access to public dental services.Liana Luzzi and A John Spence

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Psychosocial factors, dentist-patient relationships, and oral health-related quality of life: a structural equation modelling

Abstract Background Psychosocial factors and dentist-patient relationships (DPR) have been suggested to be associated with oral health outcomes. This study aimed to test a conceptual model which hypothesised relationships among psychosocial factors, DPR variables, and oral health-related quality of life (OHRQoL) in the ‘distal-to-proximal’ framework. Methods A total of 12,245 adults aged 18 years or over living in South Australia were randomly sampled for the study. Data were collected from self-complete questionnaires in 2015–2016. The outcome variable of Oral Health Impact Profile was used to measure OHRQoL. Psychosocial domain consisted of psychological well-being, social support, and health self-efficacy. DPR domain included trust in dentists, satisfaction with dental care, and dental fear. The hypothesised model was tested using the two-step approach in structural equation modelling. Results Data were analysed from 3767 respondents after the screening/preparing process (adjusted valid response rate 37.4%). In the first step of the analysis, confirmatory factor analyses produced acceptable measurement models for each of the six latent variables (GFI = 0.95, CFI = 0.98, RMSEA = 0.04). The final structural model indicated that better well-being, higher self-efficacy, and more satisfaction were associated with lower oral health impact (β = − 0.12, − 0.07, − 0.14, respectively) whereas fear was positively associated (β = 0.19). Among intermediates, support was positively associated with satisfaction within a small effect size (β = 0.06) as compared to self-efficacy with trust (β = 0.22). The invariance of the final model was also confirmed on participants’ SES and dental service characteristics except the variable of ‘last dental visit’. Conclusions Psychosocial factors and DPR variables were associated with oral health impact in both direct and indirect paths. The framework of ‘distal-to-proximal’ actions is empirically supported from psychosocial factors via DPR variables to OHRQoL

Trust in dentist-patient relationships: mapping the relevant concepts

© 2020 Eur J Oral SciTrust has a central role in healthcare encounters. This review explored concepts relevant to trust in dentist-patient relationships. The findings were demonstrated by drawing visual system maps for better understanding of the inherent complexity. A pragmatic approach was employed to search for evidence. The approach was initiated with a systematised searching protocol and followed by an iterative process of drawing maps and complementing references. The analysis-synthesis process found relevant key concepts and sub-concepts presented within three frameworks: the continuum of studying trust (utilisation, measurement, and establishment); beneficiaries of trust utilisation (patients, dentists, and oral health system); and a transformational model of trust development (identification-based, knowledge-based, and deterrence/calculus-based trust). Trust in dentist-patient relationships needs to be assessed in a multidisciplinary approach for interconnectedness among relevant concepts. The findings are represented in patient-centred care and quality of care with common underlying values. Despite the centrality of trust in medical/dental contexts, empirical evidence is insufficient beyond normative suggestions from previous studies. Based on the implications of thematic analysis and interpretation of the system maps, this paper can serve as a guide and source of information for further research of trust in dentist-patient relationships.N

Dentist-patient relationships and oral health impact in Australian adults

© 2020 John Wiley & Sons A/S. Published by John Wiley & Sons LtdObjectives: Dentist-patient relationships (DPRs) are a key component in clinical encounters with potential benefits for oral health outcomes. This study aimed to investigate whether better DPR variables are associated with higher oral health-related quality of life (OHRQoL). Methods: A total of 12 245 adults aged 18 years or over were randomly sampled from South Australia in 2015-2016. Data were collected from self-complete questionnaires and analysed as a cross-sectional design. The outcome variable was the Oral Health Impact Profile (OHIP-14). Explanatory DPR variables included trust in dentists, satisfaction with dental care, and dental fear. Covariates comprising oral health behaviours, dental services, demographics, and socioeconomic status were included as potential confounding variables. Bivariate correlation analyses and multivariable linear regression were performed for the associations among explanatory, outcome variables and other covariates. Results: Response data were analysed from 4220 participants (response rate = 41.9%). Unadjusted mean total scores of DPR variables and OHIP-14 were associated with most of the study participants' characteristics (P <.05). Bivariate correlations among DPR variables and OHIP-14 showed a diverse range of coefficients (|r| or |ρ|=0.22-0.67). Multivariable regression analyses in both individual/clustered block entry and full model indicated that higher satisfaction and less dental fear (B = –0.039 and 0.316, respectively in the full model) were associated with lower OHIP-14 after adjusting for possible confounders (P <.01). Conclusions: This study found that favourable DPR variables, mainly greater satisfaction and less dental fear are positively associated with better OHRQoL. Further studies are warranted to investigate the causality and mediation/moderation of DPR variables on oral health outcomes.N
