Recruitment, Randomization, and Allocation
The study principal investigator (I.M.K.) met with the medical directors of all 8 potentially eligible practices to invite their practice to participate, and each agreed. The 8 practices were then matched in pairs according to practice size and patient and clinician characteristics (ie, 2 practices that care for people living with HIV; 2 smaller internal medicine practices without trainees; 2 larger internal medicine practices with trainees; and 2 remaining practices—family medicine and geriatrics—without obvious pairings). Randomization was generated by the study’s (blinded) biostatistician (J.E.S.), using a random number generator to assign one practice within each matched pair to the intervention.
