Background and study aims
Dental therapies are increasingly provided with a focus on individual patient requirements and emotional well-being. Any patient-centered care of this type needs to be grounded in a meaningful relationship between the patient and the dental team, communication being the key to establishing such a relationship. It takes communicative and interpersonal skills on the dentist's part to gather all the patient-specific information that is required for a correct diagnosis and to select an appropriate process that will optimally meet each individual's therapeutic needs. Patient outcomes can be improved further by one-on-one consultations in accordance with the principle of 'shared decision-making' prior to treatment. The aim of this process is to create a trusting relationship that will allow dentists to pinpoint individual needs and raise their patients' knowledge of underlying pathologies to a level enabling them to make informed decisions related to their own health. Patient decision aids (PDAs) can be used to support shared decision-making. PDAs are believed to increase the effectiveness of communication between dentists and patients, thus optimizing patient information and patient care even further. PDAs are designed to inform about clinical problems and outcome probabilities in an easy-to-grasp fashion, usually with examples for illustration, in an effort to make sure that treatment decisions are consistent with personal values. In practice, however, patients are faced with a variety of decision requirements in dental offices, and one-on-one consultations for prosthetic treatment, in particular, will commonly include a wealth of information and treatment options to be discussed. Despite an everyday need for shared decision-making in dentistry, the PDAs which are routinely used to support the oral conversations during consultation visits are not well investigated.

Who can participate?
Patients aged ≥ 20 years old who need prosthodontic treatment

What does the study involve?
This study focused on the patient satisfaction of two different PDAs in prosthodontic consultation. Furthermore, the researchers are interested in how the patients rate the consultation as an adequately intelligible, comprehensive explanation of the treatment steps.

The study involves the usual one-to-one consultation with a dentist and in addition, two different PDAs were used. One PDA is paper-based and the other PDA is computer-based. After these consultations, all patients are asked to complete a questionnaire. Participants should plan approximately one hour of additional time for the consultation.

What are the possible benefits and risks of participating?
Being a study participant enables patients to gain a deeper insight into the possible treatment options for their individual baseline situation and subsequently make more informed decisions about their own health. At the same time, they help to better understand how dental consulations should be designed to be better understood by medical laypeople. There are no harms or risks for the patients who join the study.

Scientific titleImpact of two different patient decision aids in prosthodontic consultations: a prospective randomized clinical study
Study objectivesAs null hypotheses, it was assumed that statistical differences in patient ratings would be observable neither (i) for both PDAs versus shared decision-making by oral conversation only; nor (ii) between consultations supported by either of both PDAs.
Ethics approval(s)

Approved 16/05/2014, Ethics committee Goethe University Frankfurt (Theodor-Stern-Kai 7, Frankfurt, 60596, Germany; +49 (0)6963017239; ethikkommission@kgu.de), ref: 71/14

Health condition(s) or problem(s) studiedIncreasing the understanding of patients in a prosthetic consultation in order to realise the shared decision making process
InterventionPatients are prospectively included and randomized to either a control group involving no consultation aids except intraoral findings and radiographs (no PDA); a test group 1 involving the use of a loose-leaf publication in a cardboard box (paper-based PDA); and a test group 2 involving on-screen demonstrations (software-based PDA). Each patient is then asked to rate the consultation on a questionnaire, six key items of which will be analyzed for this study.
Intervention typeBehavioural
Primary outcome measurePatient satisfaction measured using a Likert scale in a questionnaire after prosthodontic consultations
Secondary outcome measuresOverall time for prosthodontic consultations measured using a timekeeper during the consultations process
