Table 3 Outcome parameters and instruments

From: A cluster randomised controlled trial in primary dental care based intervention to improve professional performance on routine oral examinations and the management of asymptomatic impacted third molars: study protocol

Outcome parameter

 

Instruments

Primary ROE-outcomes

Clinical Performance/decision-making:

Number of patients per GDP with assigned recall interval (months) based on individual risk profile assessment. For high-risk children and adolescents' intervals less than seven months, in case of low risk profile more than seven months; for low-risk adults' profiles, nine months equal or more, and for high-risk adults' profiles less than nine months.

Patient record, registration form, to analyse risk management

Secondary ROE-outcomes

Clinical Performance/decision-making:

Number of patients per GDP with prescribed individual frequency of BWs (months). For high-risk children and adolescents, frequencies of less than 24 months, and for low-risk profiles, frequencies of more than 36 months; for high-risk adults, prescription frequencies less than 36 months, and for low risk adults, prescription of more than 48 months. Number of patients per GDP with periodontal DPSI-score > 1, and prevalent caries, who have been given feedback, information and preventive advice, registered in patient record or registration form.

Efficacy data/cost-effectiveness scores:

Mean overall length in months of recall intervals per GDP over the past 3 yrs Mean total number of BW(s) and other radiographs over past 3 years

Type of performer GDP/Oral hygienist/others (level of graduation, education)

Total number of additional interventions performed during ROE (polishing, removal of calculus: coded as M50, M55).

Professional attitudes and compliance:

Measured at the beginning and end of the trial, by questionnaire.

Patient record, registration form, questionnaire to analyse additional performance and cost-analysis

Primary MIM-outcome

Clinical performance/decision-making:

Number of patients (between 17 -35 yr of age) with removed versus retained MIMs in accordance with CPG, or with indication for removal.

Number of risk-based assessment radiographs between 17– 35-yrs/per patient with risk-based for assessment of prognosis MIM.

Patient record, registration form to analyse risk management

Secondary MIM-outcome

Professional attitudes/compliance and feedback:

Interviews of patients (17–35 years of age) to confirm risk-based performance.
