| Scientific title | Randomised controlled trial for evaluating the prescribing impact of information meetings led by pharmacists and of new information formats in General Practice in Italy: INFANT 2 |
| Study acronym | INFANT 2 (INformazione sui FArmaci e Nuove Terapie) |
| Study objectives | Information meetings with single physicians, led by pharmacists and organised by Local Health Authorities within a large scale independent information program involving local General Practitioners (GPs), can be effective in changing physicians prescribing behaviour. |
| Ethics approval(s) | Between November 2006 and March 2007, the protocol was sent to the Local Ethics Committees (LEC) of the Health Authorities involved. Some of the LEC have already approved the protocol (Olbia, Carbonia, Sassari, Nuoro), some specifying that it was unnecessary to analyse it formally since no ethical problems arise in carrying out a randomisation differentiating the kind of information actively discussed during the outreach visits. |
| Health condition(s) or problem(s) studied | Information to physicians |
| Intervention | Three groups of single physicians will be provided with one of the following: 1. One information meeting led by a pharmacist and supported by a bulletin developed ad hoc 2. One information meeting led by a pharmacist and supported by information already available (e.g., from the Italian translation of Medical Letter, or the Drug and Therapeutics Bulletin [DTB], etc) 3. No intervention The information meetings will last half to one hour. The process described above will be repeated a second time with different topics, so that the number of comparisons and indicators is doubled and more qualitative and quantitative data are available. |
| Intervention type | Other |
| Primary outcome measure | Difference (%) in NHS prescription of drugs under scrutiny (expressed as Defined Daily Dose [DDD] per thousand inhabitants/day), comparing those who have/ have not received the specific information. Prescriptions within six months after the intervention will be evaluated. |
| Secondary outcome measures | 1. Difference in the % of patients who were prescribed the specific drug(s) 2. Difference in the % of patients who were prescribed the specific drug(s) for the first time (in the previous 12 months) 3. Difference in expenditure for the specific drug (per 1000 patients/day) 4. Difference in NHS prescription of drugs under scrutiny (expressed as DDD per thousand inhabitants/day), comparing those who have received the traditional versus enriched format, and any information versus no information 5. Differences in the main and secondary outcomes according to the number of assisted population in the related PCG 6. Adjusted difference in prescribed DDD per 1000 patients/day according to a statistical model, considering as possible covariates: 6.1. Overall prescription in DDD per 1000 patients day at baseline 6.2. Number of assisted population 6.3. Geographical location (mountain, hill, plain, urban centre according to definitions given by the Italian Statistics Institute) 6.4. Age distribution of assisted population (in quartiles) 6.5. % females in the assisted population 6.6. Physician age 6.7. Total physician drug expenditure (excluding drugs under scrutiny) 6.8. % assisted population with polyprescription (greater than or equal to three drugs of different classes) 6.9. Number of new prescriptions (in the last 12 months) 6.10. Month of evaluation 6.11. Participation to the information meetings 6.12. % exact answers to the questionnaire testing knowledge 7. Difference in knowledge (measured through the number of correct answers to a specific questionnaire) 8. Difference in attitudes (measured through the answers to a specific anonymous questionnaire) Prescriptions within six months after the intervention will be evaluated. |
