| Annotation | The Trial of Nonpharmacologic Intervention in the Elderly (TONE) is a multi-centre, randomised, controlled experimental investigation designed to evaluate the efficacy and safety of weight loss and sodium reduction in patients treated with a prescription drug for control of hypertension. The effectiveness of different approaches to participant enrolment in this behaviour modification trial were compared in men and women aged 60 to 80: mass mailing; advertising; community-based screening; participant referrals; screening in clinical practice; and other recruitment approaches. Visit counts were assessed at each stage of the screening and randomisation process. Logistic regression was used to contrast the randomisation yields for different recruitment strategies, and to explore the impact of socio-demographic characteristics and geographic location of recruitment yields. Overall randomisation yields from a pre-screen contact and a first screening visit to enrolment in the trial were 11% and 31%, respectively. Randomisation yields varied significantly by participant age, education, and marital status. Recruitment for trials of non-pharmacological interventions in older people using media campaigns is feasible. (RH). |
