263 participants completing a randomised controlled trial comparing telephone vs. face-to-face asthma consultations were asked about preferences for future reviews. Qualitative analysis of data from 209 respondents identified divergent views. Clear opinions were expressed about the respective roles of the two modes of consulting; telephone consultations were considered convenient for reviewing 'well controlled' asthma, whereas face-to-face consultations were perceived as allowing in-depth assessment of problems in those with more symptomatic asthma. Practices may consider offering patients the choice of a telephone or face-to-face review.
