[Monitoring and impact of the disclosure of five health alerts for drugs in Colombia].

Objective: Make the notification and monitoring compliance with five health drug alerts to a group of health care providers in Colombia.

Methods: Quasi-experimental, prospective, before-after study, without control group, by intervening in physician prescribers of ketoconazole, metoclopramide, nimesulide, diacerein, strontium ranelate. The affiliated population of the contributory system of the Colombian Health System was taken as the universe population sample from 13 health promoting entities (EPS) of Colombia. Patients receiving monthly these drugs prior to the alert were identified. An educational intervention was performed and then the rate of change in the dispensation was measured.

Results: About 26 different activities were conducted on 500 prescribers. Out of a total of 4 121 954 people, 13 979 patients were identified monthly in 2013, who received some of the five medications. Likewise, a reduction in 1,470 subjects per month (-10.5%) for 2014 was observed. The drug which achieved the greatest reduction was ketoconazole (-31.1% of cases), followed by strontium ranelate (-30.3%) and metoclopramide (-8.6%). For nimesulide (+ 0.7%) and diacerein (+ 16.4%) no favorable results were obtained.

Conclusions: Patients with potentially risky prescriptions remain in Colombia; educational pharmacovigilance interventions made after the report alerts given by drug regulatory agencies may decrease the proportion of patients using these drugs.
