Background: Routine oral examination (ROE) refers to periodic monitoring of the general and oral health status of patients. In most developed Western countries a decreasing prevalence of oral diseases underpins the need for a more individualised approach in assigning recall intervals for regular attendees instead of systematic decision making of fixed intervals. From a quality of care perspective as well, one can also question the effectiveness of the widespread prophylactic removal of mandibular impacted asymptomatic third molars (MIM) in adolescents and adults. It is as yet unclear how quality of oral care can be improved. Research data on effectiveness of interventions to promote continuing professional development for dentists are rare.
Methods/Design: This implementation study is a cluster randomised controlled trial with groups of GDPs as the unit of randomisation. The aim of the study is to determine the effectiveness and efficiency of small group quality improvement on professional decision making of general dental practitioners (GDPs) in daily practice. Six peer groups ('IQual-groups') shall be randomised either to the intervention group I or group II. Groups of GDPs allocated to either of these arms act as each other's control group. An IQual peer group consists of 8-10 GDPs who attend in monthly structured sessions scheduled for discussion on practice related topics.
GDPs in both trail arms receive recent developed evidence-based CPG on ROE or MIM respectively. The implementation strategy consists of 1 interactive IQual circle meeting of mostly 2-3 hours. In addition, both groups of GDPs receive feedback on personal and group characteristics and are invited to make use of web-based patient vignettes for further individual training on risk assessment policy. A few weeks after the interactive meeting reminders (flow charts) will be send by mail.
The main outcome measure for the ROE-study and control group is the use and appropriateness of individualised risk assessment in assigning recall intervals and for the MIM-study the use and appropriateness of individualised mandibular impacted third molar risk management.
Measurements (pre-intervention data collection) will take place in months 1-3, starting in September 2006. Post-intervention data collection will be performed after 9 months.
Discussion: In most developed Western countries a decreasing prevalence of oral diseases underpins the need for a more individualised approach in assigning recall intervals for regular attendees. If the evaluation of this multifaceted implementation study reveals a shift in individual performance of GDPs in assessing risks for oral disease, further research questions and efforts to a risk-based professional education could be promoted.
Scientific hypothesis Multifaceted implementation of consensus based clinical practice guidelines (CPGs) for GDPs on ROEs and the management of asymptomatic impacted third molars (MIM) in daily dental practice is more effective and efficient compared to only dissemination of CPGs.
