Longitudinal comparison of factors influencing choice of dental treatment by private general practitioners

The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.Background: Service rate variations and appropriateness of care issues have focused attention on factors that influence treatment decisions. The aims of this study were to examine what factors dentists consider in choosing alternative treatments, the stability of these factors over time and whether stability of treatment choice was related to age of dentist. Methods: Baseline data were collected by mailed self-complete questionnaires from a random sample of Australian dentists (response rate=60.3 per cent, n=345 private general practitioners provided service data from a typical day) in 1997–1998 and followup data were collected in 2004 (response rate=76.8 per cent, n=177 matched longitudinal cases). Results: The most frequent factors considered important across six alternative treatment pair choice scenarios were caries rate for ‘exam v. x-ray’, age of patient for ‘preventive v. restorative intervention’, cost of treatment for ‘crown v. buildup’, ‘root canal v. extraction’ and ‘bridge v. denture’, and calculus for ‘prophylaxis v. scaling’. The only differences over time were (t-test, P<0.05): higher proportions of responses in the mouth status group at follow-up for ‘exam v. x-ray’; higher proportions of responses in the visit history group at follow-up for ‘preventive v. restorative intervention’; a lower proportion of responses in the caries group at follow-up for ‘crown v. build-up’; and a higher proportion of responses in the treatment constraints group at follow-up for ‘prophylaxis v. scaling’. Conclusions: While a wide range of responses were offered as factors influencing the choice of alternative treatments, cost of treatment was a major consideration in situations where significantly cheaper alternatives existed, while patient preference was commonly included as a secondary consideration across a wide range of treatment choice scenarios. The treatment choice responses showed a high degree of stability over time across all age groups of dentists, suggesting that if routines are developed these are established before or soon after graduation as a dentist.DS Brennan, AJ Spence

Job satisfaction of registered dental practitioners

The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.Background: This study was designed to measure job satisfaction among registered clinical dentists so as to identify issues which may influence recruitment and retention of dentists in active clinical practice. Methods: A questionnaire measuring dimensions of job satisfaction was mailed to a stratified random sample of 80 private and 80 public sector dentists selected from the 1999 Victorian Dental Register. Results: An adjusted response rate of 60 per cent was achieved (n=87). Analyses showed significant differences (ANOVA; p<0.05) in levels of satisfaction for various dimensions of job satisfaction by gender, age group and practice type. Differences in job satisfaction between male and female dentists related to the personal time dimension. Differences in satisfaction between dentists of different age groups were attributable to six dimensions: relationships with colleagues, relationships with patients, relationships with staff, personal time, community and administrative responsibilities. Differences between levels of satisfaction among private and public dentists related to the autonomy, relationships with patients, pay and resources dimensions. Conclusion: There are various dimensions of job satisfaction that may be pertinent to issues influencing recruitment and retention of dentists. Differences that exist between levels of job satisfaction among private and public sector dentists, between male and female dentists and dentists of different age groups need to be addressed in order to improve recruitment and retention rates of dentists in active clinical practice in different sectors of the dental care system.L.

Practice profiles of Australian private general dental practitioners

The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.In Australia, the vast majority of dental practitioners are in the private sector (83 per cent). The provision of oral health services is dominated by general practitioners (85 per cent), with a small percentage of practitioners in specialist and restricted practice (12 per cent), and the remainder in areas such as administration, teaching and research. This paper describes the profile of patients and their presenting conditions among private general dental practitioners in 2003–2004.Prepared by David S Brennan and A John Spence

Responsibility loadings for dental services by general dentists

Extent: 6p.BACKGROUND: Responsibility loadings determine relative value units of dental services that translate services into a common scale of work effort. The aims of this paper were to elicit responsibility loadings for a subset of dental services and to relate responsibility loadings to ratings of importance of the components of responsibility. METHODS: Responsibility loadings and ratings of components of responsibility were collected using mailed questionnaires from a random sample of Australian private general practice dentists in 2007 (response rate = 77%). RESULTS: Median responsibility loadings were 1.25 for an initial oral examination and for a 3+-surface amalgam restoration, 1.50 for a simple extraction and for root canal obturation (single canal), and 1.75 for subgingival curettage (per quadrant). Across the five services coefficients from a multivariate logit model showed that ratings of importance of knowledge (0.34), dexterity (0.24), physical effort (0.28) and mental effort (0.48) were associated with responsibility loadings (P < 0.05). CONCLUSIONS: The elicited median responsibility loadings showed agreement with previous estimates indicating convergent validity. Components of responsibility were associated with loadings indicating that components can explain and predict responsibility aspects of dental service provision.David S. Brennan and A. John Spence

Practice activity trends among oral and maxillofacial surgeons in Australia

BACKGROUND: The aim of this study was to describe practice activity trends among oral and maxillofacial surgeons in Australia over time. METHODS: All registered oral and maxillofacial surgeons in Australia were surveyed in 1990 and 2000 using mailed self-complete questionnaires. RESULTS: Data were available from 79 surgeons from 1990 (response rate = 73.8%) and 116 surgeons from 2000 (response rate = 65.1%). The rate of provision of services per visit changed over time with increased rates observed overall (from 1.43 ± 0.05 services per visit in 1990 to 1.66 ± 0.06 services per visit in 2000), reflecting increases in pathology and reconstructive surgery. No change over time was observed in the provision of services per year (4,521 ± 286 services per year in 1990 and 4,503 ± 367 services per year in 2000). Time devoted to work showed no significant change over time (1,682 ± 75 hours per year in 1990 and 1,681 ± 94 hours per year in 2000), while the number of visits per week declined (70 ± 4 visits per week in 1990 to 58 ± 4 visits per week in 2000). CONCLUSIONS: The apparent stability in the volume of services provided per year reflected a counterbalancing of increased services provided per visit and a decrease in the number of visits supplied

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

Household income modifies the association of insurance and dental visiting

BACKGROUND Dental insurance and income are positively associated with regular dental visiting. Higher income earners face fewer financial barriers to dental care, while dental insurance provides partial reimbursement. The aim was to explore whether household income has an effect on the relationship between insurance and visiting. METHODS A random sample of adults aged 30–61 years living in Australia was drawn from the Electoral Roll. Data were collected by mailed survey in 2009–10, including age, sex, dental insurance status and household income. RESULTS Responses were collected from n = 1,096 persons (response rate = 39.1%). Dental insurance was positively associated with regular visiting (adjusted prevalence ratio (PR) = 1.18; 95% CI: 1.01-1.36). Individuals in the lowest income tertile had a lower prevalence of regular visiting than those in the highest income group (PR = 0.78; 95% CI: 0.65-0.93). Visiting for a check-up was less prevalent among lower income earners (PR = 0.65; 95% CI: 0.50-0.83). Significant interaction terms indicated that the associations between insurance and visiting varied across income tertiles showing that income modified the effect. CONCLUSIONS Household income modified the relationships between insurance and regular visiting and visiting for a check-up, with dental insurance having a greater impact on visiting among lower income groups.Olga Anikeeva, David S Brennan and Dana N Teusne

Contextual and individual factors associated with dental services utilisation by Brazilian adults: A multilevel analysis

BACKGROUND: Inequalities in the utilisation of dental services in Brazil are remarkable. The aim of this study was to evaluate the association of contextual and individual factors with the utilisation of dental services by Brazilian adults using the Andersen's behavioural model. METHODS: Individual-level data from 27,017 adults residents in the State capitals who were interviewed in the 2013 Brazilian National Health Survey were pooled with contextual city-level data. The outcomes were non-utilisation of dental services and last dental visit over 12 months ago. Individual predisposing variables were age, sex, race/skin colour, schooling and social network. Individual enabling variables included income, health insurance and registration in primary health care. Individual need variables were self-perceived dental health and self-reported missing teeth. Multilevel logistic regression models were performed to estimate odds ratio (OR) and 95% confidence intervals (95% CIs) of the association of contextual and individual predisposing, enabling and need-related variables with dental services outcomes. RESULTS: Predisposing (OR = 0.89; 95% CI 0.81-0.97) and enabling (OR = 0.90; 95% CI 0.85-0.96) contextual factors were associated with non-utilisation of dental services. Individual predisposing (sex, race/skin colour, schooling), enabling (income, health insurance) and need (self-perceived oral health, missing teeth) were associated with non-utilisation of dental services and last dental visit over 12 months ago. The latter was also associated with other individual predisposing (age, social network) and need (eating difficulties due to oral problems) characteristics. CONCLUSIONS: Individual and contextual determinants influenced dental services utilisation in Brazilian adults. These factors should be on the policy agenda and considered in the organisation of health services aiming to reduce oral health inequalities related to access and utilisation of dental services
