ANALYSIS OF THE EFFICIENCY OF DENTAL HISTORY TAKING USING A DIGITAL SYSTEM WITH INTEGRATED DATA QUALITY CONTROL

Relevance. Dental history taking, regulated by Order No. 834n of the Russian Ministry of Health and Federal Law No. 323-FZ, is traditionally performed using paper questionnaires, which is associated with incomplete data entry (up to 40–60 % of clinically relevant items missing), failure to identify anesthetic risk factors, and the absence of mechanisms to verify the reliability of self-reported data. The introduction of electronic documentation systems in Russian dental practice remains fragmentary, and multi-level psychometric tools for validating patient responses in clinical questionnaires have not previously been applied. Aim. To analyse the efficiency of an interactive electronic questionnaire for dental history taking with an integrated data quality control system and automatic ASA anesthetic risk classification. Materials and methods. For the purposes of the study, an electronic multi-level health questionnaire synchronized with a medical information system was developed. The questionnaire was created with handwritten code; data storage, processing, and transmission were carried out using Russian software on servers located in the Russian Federation. A randomized controlled pilot study (n = 251) was conducted at a dental clinic in St. Petersburg: a control group (n = 124, paper questionnaire) and an experimental group (n = 127, electronic questionnaire). The primary endpoint was the total time of history taking. Secondary endpoints included data completeness, disease detection rate, patient satisfaction, and the composite validity index (CVI). Results. The electronic questionnaire reduced the total history-taking time by 36–43 % (p < 0.001), increased completeness from 61.3 % to 94.5 %, doubled disease detectability, and increased medication detectability 2.5-fold. Mean CVI was 78.4 (SD 14.2); 73.2 % of questionnaires were deemed valid. The completion rate was 94.5 %.
