[Randomized evaluation of two teaching methods using aerosol dosers].
The administration of antiasthmatic drugs by pressurised aerosols is limited by the difficulties of the inhalation technique. The development of teaching aids may help their use. The aim of this study was to assess and to compare 2 educational methods of inhalation: a standardised inhalation card and a video film. Forty five asthmatic patients who were poor coordinators were separated randomly into 3 groups: education by card, education by video film and a third group served as a positive control and had been educated by video film and also an additional education in a room set aside for teaching inhalation techniques. The FEV1 (VEMS) had been read before the education session and 15 days after, and on each occasion before and after inhalation of a beta-2-mimetic. An inhalation score was measured on the same date. The 2 educational methods enabled an improvement in the score to be shown which was more marked in the video group than in the card group. The VEMS (mean + or - one standard deviation) before inhalation of beta-2-mimetics was significantly superior to J15 in relation to J1 in the video group (2.38 +/- 0.84 and 1.89 +/- 0.61 respectively) and in the control group (2.05 +/- 0.81 and 1.71 +/- 0.66 respectively) whilst the values did not differ in the card group (2.09 +/- 0.63 and 2.01 +/- 0.7 respectively). This study suggests the value of education of these patients and the superiority of video education in relation to reading a standardised card in the optimisation of treatment administered by the inhaled route.
