title: Impact of information leaflets on behavior of patients with gastroenteritis or tonsillitis: a cluster randomized trial in French primary care.
abstract: OBJECTIVE
  To assess the impact of four patient information leaflets on patients' behavior in primary care.
  
  
  METHODS
  Cluster randomized multicenter controlled trial between November 2009 and January 2011.
  
  
  METHODS
  French adults and children consulting a participating primary care physician and diagnosed with gastroenteritis or tonsillitis. Patients were randomized to receive patient information leaflets or not, according to the cluster randomization of their primary care physician.
  
  
  METHODS
  Adult patients or adults accompanying a child diagnosed with gastroenteritis or tonsillitis were informed of the study. Physicians in the intervention group gave patients an information leaflet about their condition. Two weeks after the consultation patients (or their accompanying adult) answered a telephone questionnaire on their behavior and knowledge about the condition.
  
  
  METHODS
  The main and secondary outcomes, mean behavior and knowledge scores respectively, were calculated from the replies to this questionnaire.
  
  
  RESULTS
  Twenty-four physicians included 400 patients. Twelve patients were lost to follow-up (3 %). In the group that received the patient information leaflet, patient behavior was closer to that recommended by the guidelines than in the control group (mean behavior score 4.9 versus 4.2, p < 0.01). Knowledge was better for adults receiving the leaflet than in the control group (mean knowledge score 4.2 versus 3.6, p < 0.01). There were fewer visits for the same symptoms by household members of patients given leaflets (23.4 % vs. 56.2 %, p < 0.01).
  
  
  CONCLUSIONS
  Patient information leaflets given by the physician during the consultation significantly modify the patient's behavior and knowledge of the disease, compared with patients not receiving the leaflets, for the conditions studied.
