Recruitment difficulties in a home telecare trial

Abstract

We analysed the difficulties encountered in recruiting predominantly older patients, suffering from an acute exacerbation of a chronic illness, to a randomized controlled trial of home telecare. Of 653 patients approached for study participation, after full assessment, 80% (519) met the trial eligibility criteria. Of these, 104 (20%) consented to study participation and 415 (80%) refused. A logistic regression model was constructed to examine independent effects of patient factors on probability of trial participation. Only two independent variables were associated with decreased likelihood of consent: increasing age (1 year older: odds ratio [OR] = 0.96); and being on inhaled steroid medication (OR = 0.60). The most common reason for refusal to participate, accounting for almost one-third of respondents, was a stated preference for a face-to-face nurse visiting service rather than a telecare service. Perhaps home telecare services should continue to be targeted at the more stable chronically ill population and not at those suffering from acute illness.
