Dental schools establish quality assurance (QA) programs that are intended to improve patient care, comply with requirements of liability carriers and regulatory agencies, and maintain accreditation. Data collection, trend analysis, and interventions are typically used in QA programs to monitor and improve compliance. The purpose of this article is to discuss unfavorable trends and examine the effect of targeted interventions in three clinical operations: infection control, removable prosthodontics, and case reviews of students' patient care in progress (interim case reviews) at a U.S. dental school. Infection control compliance was evaluated and interventions were implemented beginning in 2002 to correct unfavorable trends in two protocols: placement of students' mobile supply cart and the use of overgloves. A predelivery esthetic consent was introduced in spring 2004 to decrease esthetic failures in removable prosthodontics. For interim case reviews, two areas received interventions going back to 2003: reevaluation following initial periodontal therapy and orthodontic screening. The data presented are not meant to show conclusive success of particular interventions, but to display broad trends and suggest methods to manage quality assurance parameters. These trends suggest we had better success with the interventions that were simple, valuable, measurable, and repeatable than with interventions that less fit these criteria.
