Is it cost-beneficial to society? Measuring the economic worth of dental residency training

Abstract

This study estimated whether continued programming of a highly specialized four-year dentistry residency training in Saudi Arabia was cost-beneficial. We utilized a purposive sampling to administer a survey to trainees in major cities. Additionally, we used publically available market information about general practitioners. We employed Benefit-Cost Analysis accounting approach as a conceptual framework. Using general practitioners as the base category, we grouped overall social analytical perspectives into resident trainees and rest of society. The residency program was cost-beneficial to trainees, realizing an estimated return of SR 4.07 per SR 1 invested. The overall societal return was SR 0.98 per SR 1 invested, slightly shy of a bang for the buck, in part because the public sector largely runs the training. Benefits included increased earnings and enhanced restorative dentistry skills accruing to trainees; increased charitable contributions and programming-related payments accruing to programs and the public; and practice-related payments accruing to governmental, professional, and insurance agencies. Rest of society, notably government underwrote much of the cost of programming. A sensitivity analysis revealed the results were robust to uncertainties in the data and estimation. Our findings offer evidence to evaluate whether continued residency training is cost-beneficial to trainees and potentially to overall society.
