A conducted analysis of volume and cost of dental care provided in outpatient settings proves the need for harmonization of Russian Ministry of Health's documentation regulating dental checks in adults and children, and the Programme of state guarantees.

IQuaD dental trial; improving the quality of dentistry: a multicentre randomised controlled trial comparing oral hygiene advice and periodontal instrumentation for the prevention and management of periodontal disease in dentate adults attending dental primary care.

BACKGROUND: Periodontal disease is the most common oral disease affecting adults, and although it is largely preventable it remains the major cause of poor oral health worldwide. Accumulation of microbial dental plaque is the primary aetiological factor for both periodontal disease and caries. Effective self-care (tooth brushing and interdental aids) for plaque control and removal of risk factors such as calculus, which can only be removed by periodontal instrumentation (PI), are considered necessary to prevent and treat periodontal disease thereby maintaining periodontal health. Despite evidence of an association between sustained, good oral hygiene and a low incidence of periodontal disease and caries in adults there is a lack of strong and reliable evidence to inform clinicians of the relative effectiveness (if any) of different types of Oral Hygiene Advice (OHA). The evidence to inform clinicians of the effectiveness and optimal frequency of PI is also mixed. There is therefore an urgent need to assess the relative effectiveness of OHA and PI in a robust, sufficiently powered randomised controlled trial (RCT) in primary dental care. METHODS/DESIGN: This is a 5 year multi-centre, randomised, open trial with blinded outcome evaluation based in dental primary care in Scotland and the North East of England. Practitioners will recruit 1860 adult patients, with periodontal health, gingivitis or moderate periodontitis (Basic Periodontal Examination Score 0-3). Dental practices will be cluster randomised to provide routine OHA or Personalised OHA. To test the effects of PI each individual patient participant will be randomised to one of three groups: no PI, 6 monthly PI (current practice), or 12 monthly PI.Baseline measures and outcome data (during a three year follow-up) will be assessed through clinical examination, patient questionnaires and NHS databases.The primary outcome measures at 3 year follow up are gingival inflammation/bleeding on probing at the gingival margin; oral hygiene self-efficacy and net benefits. DISCUSSION: IQuaD will provide evidence for the most clinically-effective and cost-effective approach to managing periodontal disease in dentate adults in Primary Care. This will support general dental practitioners and patients in treatment decision making. TRIAL REGISTRATION: Protocol ID: ISRCTN56465715.

Development of effectiveness of care and use of services measures for dental care plans.

OBJECTIVES: Standardized measures to assess clinical aspects of the performance of managed dental care plans are not available. This project sought to develop and evaluate measures for effectiveness of care and use of services that could be calculated using a plan's administrative data. METHODS: Two panels of stake holders representing dental plans, purchasers, and dental providers participated in a modified Delphi process to refine initial sets of effectiveness of care and use of services measures modeled after HEDIS measures for medical care. The refined measures were then pilot tested in two dental health maintenance organizations. RESULTS: The development process resulted in specification of seven effectiveness of care measures assessing disease activity classification, and prevention and outcomes for caries, periodontal disease, and tooth loss. Six use of services measures focusing on prophylaxes, third molar surgery, preventive, restorative, prosthetic, surgical, and endodontic care also were specified. Pilot testing of the measures indicated reasonable reliability and sensitivity, but also demonstrated the need for supervision or auditing of the process. CONCLUSIONS: These standardized measures for dental care plan performance are available for immediate use. However, because the measures depend on diagnostic information (periodontal probing data and diagnoses associated with restorative treatments) in the administrative data set, their adoption will require changes in most plans' data systems and data collection policies.

Evaluation of audit-based performance measures for dental care plans.

OBJECTIVES: Although a set of clinical performance measures, i.e., a report card for dental plans, has been designed for use with administrative data, most plans do not have administrative data systems containing the data needed to calculate the measures. Therefore, we evaluated the use of a set of proxy clinical performance measures calculated from data obtained through chart audits. METHODS: Chart audits were conducted in seven dental programs--three public health clinics, two dental health maintenance organizations (DHMO), and two preferred provider organizations (PPO). In all instances audits were completed by clinical staff who had been trained using telephone consultation and a self-instructional audit manual. The performance measures were calculated for the seven programs, audit reliability was assessed in four programs, and for one program the audit-based proxy measures were compared to the measures calculated using administrative data. RESULTS: The audit-based measures were sensitive to known differences in program performance. The chart audit procedures yielded reasonably reliable data. However, missing data in patient charts rendered the calculation of some measures problematic--namely, caries and periodontal disease assessment and experience. Agreement between administrative and audit-based measures was good for most, but not all, measures in one program. CONCLUSIONS: The audit-based proxy measures represent a complex but feasible approach to the calculation of performance measures for those programs lacking robust administrative data systems. However, until charts contain more complete diagnostic information (i.e., periodontal charting and diagnostic codes or reason-for-treatment codes), accurate determination of these aspects of clinical performance will be difficult.

The effects of managed care on the quality of dental hygiene care.

PURPOSE: This study examined whether patients insured by a managed dental care plan receive lower quality dental hygiene care than those not enrolled in a managed dental care plan. METHODS: Questionnaire data were gathered from 193 dental hygienists in the Chicago, Illinois area. Managed care was measured by a questionnaire item that assessed the proportion of managed care patients treated by the subject; quality of dental hygiene care was measured by items that assessed the extent to which the subject performed each of 23 dental hygiene tasks. RESULTS: A factor analysis of the 23 items assessing the quality of dental hygiene care indicated four meaningful factors named: periodontal procedures, appointment time, visual examinations, and oral examinations. Measures based on these factors were the dependent variables in regression analysis that included managed care as the primary independent variable and demographic characteristics of the subjects and their practices as control variables. Managed care had a significant (p < .05) negative relationship with appointment time, but did not have a significant relationship with periodontal procedures, visual examinations, or oral examinations. CONCLUSION: This study suggests that managed dental care program patients may have inadequate appointment time with a dental hygienist, which may affect whether they receive important services, such as oral health education. Dental hygienists in managed-care environments should be certain they are making effective use of the scheduled appointment time and procedures to ensure managed-care patients receive adequate time for dental hygiene care.
