Table 5 Relative risks and 95% confidence intervals for a laboratory test (LT) being requested in one medical consultation comparing Family physicians and Generalists (adjusted for age, sex, social development index and Charlson comorbidity index) in PHC, the respective Population Attributable Fractions (PAFs) and the change in the absolute numbers of LTs requested in a scenario in which all medical consultations were performed by Family Physicians.

  1. All p-values were smaller than 0.001
  2. Generalists (reference group) are doctors without residency training in Family Medicine
  3. Family physicians are graduated FPs, FM preceptors and residents enrolled in Family Medicine training
