Service provision by patient and visit characteristics in Australian oral and maxillofacial surgery: 1990 to 2000

This study was set-up to describe main areas of service by patient and visit characteristics and compare trends in services between 1990 and 2000. All registered oral and maxillofacial surgeons in Australia were surveyed in 1990 and 2000 using mailed self-complete questionnaires. Service provision data were collected from a one-week log. Data were available from 79 surgeons from 1990 (response = 73.8%) and 116 surgeons from 2000 (response = 65.1%). Service distributions were dominated by dentoalveolar surgery in 1990 (66.6%) and 2000 (63.5%). Multivariate analysis showed: patient age, location of visit (office/theatre/inpatient facility) and referral source (general/specialist and dental/medical) were associated with all five main areas of service; type of visit (consult/operation/review) was associated with four main areas; patient sex and place of visit (private/public) was associated with three main areas; the only significant change over time was an increased percentage of orthognathic surgery, odds ratio = 1.4 (95% CI: 1.1-1.7) times higher in 2000 compared to 1990. Main areas of service were associated with a range of explanatory variables such as age and sex of patients, and place, location and type of visit, and referral source. However, the distribution of services remained relatively stable over time.
