Background and study aims
Although primary care dentists are generally aware of problems related to antibiotic resistance, in German dental primary care antibiotics are prescribed too often. Qualitative open-ended interviews and group discussions with primary care dentists showed that there are multiple reasons. Uncertainty (e.g. related to recent changes concerning the prophylaxes of endocarditis), perceived prescription pressure of patients suffering from severe pain (especially during emergency services), and unawareness play a major role here. The DREAM trial will test an intervention that aims at optimizing the prescription of antibiotics in dental care.

Who can participate?
The DREAM trial will include more than 50 dentists of the German region of Mecklenburg-Western Pomerania. Participating dentists will provide data on the amount of patients they take care of as well as on the number of antibiotics prescribed. This information will be derived from dentists practice software systems. All together, information on more than 46,000 patients will be included and scientifically analyzed. In addition, microbiological analyses will be performed within a subgroup of patients suffering from oral infections. These analyses will give insights into the level and development of microbial resistance.

What does the study involve?
During three six-month periods of data collection, information on the number of patients and antibiotic prescriptions will be collected. After the first data collection period, dentists will be randomly allocated to the intervention or control group. Dentists of the intervention group will attend a training session that aims at optimizing antibiotic prescribing. Dentists of the control group will provide care as usual. The antibiotic prescription rates of the two groups will be compared. Further, patients included in the subgroup of microbiological analyses will be asked to provide oral swabs at three different points in time. During a telephone interview, these patients will also be asked to provide information on the duration of treatment, the use of medical services, re-consultation, pain, and adverse effects related to antibiotic treatment.

What are the possible benefits and risks of participation?
Patients of the intervention group might benefit from their doctors increased awareness towards unnecessary antibiotic prescriptions. In the best case, patients benefit from more appropriate antibiotic prescribing. It is unlikely that the trial will harm patients.

Where is the study run from?
Institute of General Practice, the Clinic for Tooth Conservation and Periodontology, and the Department of Medical Microbiology, Virology and Hygiene, all located at the Rostock University Medical Center, Germany. The three institutions form one study centre.

When is the study starting and how long is it expected to run for?
The recruitment of dentists started in September 2012. Data collection started in January 2013 and will be finished by December 2014. The project is expected to run until March 2015.

Who is funding the study?
Funding is provided by the German Federal Ministry of Health (Bundesministerium für Gesundheit, BMG).

Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	GP practice
Study type	Prevention

Scientific title	Dental care REsistance prevention and Antibiotic prescribing Modification A cluster-randomised controlled trial in German dental primary care
Study acronym	DREAM
Study objectives	The DREAM trial will test the effectiveness of a multifaceted educational intervention aiming at the reduction of inappropriate antibiotic prescribing in dental primary care. Care as usual serves as control.
Ethics approval(s)	The ethics protocol was approved by the ethics committee of the University Medical Center Rostock (Ethikkommission an der Medizinischen Fakultät der Universität Rostock) on 18th December 2012. The reference number is A 2012-0147.
Health condition(s) or problem(s) studied	Antibiotic prescribing in dental primary care
Intervention	The intervention involves elements of local consensus formation, antibiotic prescription feedback, and communication training. Training of the intervention group will be organized within small group sessions. Control: Care as usual
Intervention type	Other
Primary outcome measure	Dentists overall antibiotic prescription rate. Data is collected over a six-month baseline period (T0), at T1 (month 10 to 15), and T2 (month 19 to 24)
Secondary outcome measures	Secondary outcomes for the subgroup: 1. Severity of illness 2. Pain (VAS) 3. Duration of treatment 4. Re-consultation rate 5. Use of medical services 6. Adverse effects related to antibiotic treatment
Overall study start date	01/09/2012
Completion date	31/03/2015
