Evaluation of service provision patterns during a public-funded dental program

Area of Science:

• Public Health
• Dental Health Services Research
• Health Policy Analysis

Background:

• The Commonwealth Dental Health Program (CDHP) was established in 1994 to address barriers to dental care for adult health card holders.
• The program aimed to improve access to timely and appropriate dental services.

Purpose of the Study:

• To compare the patterns of dental service provision during the initial three years of the CDHP (1994-1996).
• To analyze changes in the types and rates of dental services utilized by public-funded patients.

Main Methods:

• Cross-sectional surveys of adult public-funded dental patients in Australia.
• Data collected for 1994 (17,653 visits), 1995 (80,098 visits), and 1996 (69,159 visits).
• Statistical analyses including chi-square tests and Poisson regression were used to identify trends and associations.

Main Results:

• A reduction in emergency dental visits was observed, decreasing from 38.9% in 1994 to 33.6% in 1995, then slightly increasing to 35.6% in 1996.
• Significant changes in service rates included increases in restorative (1.27) and endodontic (1.88) services, and decreases in prosthodontic (0.90), periodontic (0.72), and preventive (0.43) services.
• The overall number of dental services provided per visit declined over the study period.

Conclusions:

• The CDHP led to a shift in service patterns, characterized by higher rates of restorative and endodontic treatments.
• Rates of preventive and periodontic services decreased, and there was no significant reduction in extraction rates.
• Sustained improvements in dental care patterns, particularly a shift towards prevention and maintenance, may necessitate longer program durations and structural modifications.
