Aim: To establish the perceived acceptability of the use of the Denplan/Previser Patient Assessment tool (DEPPA) by patients. The secondary aim was to examine dental practitioners' views about the effects of a DEPPA consultation on patients' future oral health behaviours.Method: Two questionnaire surveys: 365 patients attending general dental practice, who had been assessed using the DEPPA software; 12 dental practitioners who had completed a DEPPA assessment on the patients.
Participants (both patients and GDPs) completed the Treatment EvaluationInventory (TEI) to ascertain their views of the DEPPA assessment.Findings: The overall mean for the Treatment Evaluation Instrument for the patients was 23.81 (SD 5.08), and for GDPs 23.81 (SD 2.99).Conclusion: Participants expressed a high level of expressed acceptability of the DEPPA tool. In particular, the tool is seen as enhancing the relationship between the patient and practitioner and providing information to support behaviour change.
3The Denplan/Previser Patient Assessment tool (DEPPA, 1) is an online tool for the assessment of patients in Denplan Excel accredited practices. It seeks to assess the risk of future disease on the basis of risk factors identified from the patient's medical history, dental history, lifestyle and current clinical condition. DEPPA also produces a score to indicate the patient's current state of oral health. The programme benefits from extensive empirical validation of its evidence based algorithms (2). The disease risk DEPPA provides is personalised, uses risk scores and can incorporate graphs and as such, is set to communicate disease risk using the best available evidence. A recent review of risk assessment tools for periodontal disease (3) identified that five such instruments exist, and further that risk assessment tools such as DEPPA can be used to predict future deterioration in periodontal health in the absence of treatment. However there is little published literature on the effect of risk communication on patient behaviour, and the acceptability of such measure to patients and dental practitioners.
Risk communication of future disease has a long research tradition (4-7).What is clear is that healthcare professionals and patients alike have difficulties conveying and understanding risk information, especially when such information is communicated in general ways (e.g. "you are at risk for gum disease') and uses long future time-frames (8,9). It is now accepted that where disease risk communication takes place this information should be tailored to the individual and communicated using simple risk scores and graphs (6). with care. Though it has been argued that the concept of 'satisfaction' was often used uncritically and without an analysis of the theoretical basis for the construct (11). Furthermore, a review of patient satisfaction studies in dentistry undertaken by Newsome and Wright (12,13) identified that there was a lack of psychometrically sound measures of patient satisfaction with dental services; most studie...
