Age and number of drugs prescribed
However, the number of prescribed drugs was correlated to the age in our sample (r=0.42; p<0.00001) (data not shown). After adjusting for number of prescribed drugs, the proportion of patients reaching the therapeutic goals was the same, whatever their age or study group for patients who took less than five different drugs (Table 3). Conversely, for polypharmacy patients, the proportions are higher in the intervention group. The difference between the control and the intervention group is non-significant for patients under 60 (20.0%vs. 66.7%; p=0.242) and significant for patients over 60 (15.8%vs. 57.1%; p=0.024).

Number of chronic disease

The proportion of patients achieving therapeutic goals decreased with the number of pathologies in both groups (Table 2). This proportion stay higher in the intervention group than in the control group, whether patients had one (50.0% vs. 77.7%), two (33.3% vs.70.0%) or more (27.3% vs. 46.7%) chronic diseases, although no significant differences were retrieved.

Socio-economic level

In the control group, the proportion of patients achieving therapeutic goals decreased as the socio-economic level increased (37.5% to 29.4%) (Table 2). It seemed to be the opposite in the intervention group, in which it increased with the socio-economic level (37.5% to 68.8%) (Table 2). There was no difference between the two groups for lower education levels (37.5%). The difference appeared for middle education levels (33.3% vs 70.0%; p=0.302) and get significant for higher education levels (29.4% vs 68.8%; p=0.024).

Main pathology involved

The increase of the proportion of patients reaching the therapeutic goals in the intervention group seemed to be the same order of magnitude (+24% and +23%) in hypertension (38.5% vs. 62.5% p=0.089) and type 2 diabetes (10.0% vs. 33.3%; p=0.303), and more important (+42%) in hypercholesterolemia (37.5% vs. 80.0%; p=0.266) (Table 2).
