An interventional study of Telephone reminder call in Asthma, Sleep Apnea Syndromes and Tuberculosis, sponsored by Imperial College London. Completed at 1 site in United Kingdom. Open to participants aged 18 Years to 90 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-02-05.
Sponsored by Imperial College London · Not applicable, Interventional, and Health services research
Many studies have shown a high non-attendance rate in hospital outpatient clinics. The investigators have found a non-attendance rate of 25% in their asthma clinics and would like to investigate whether a reminder phone call will improve attendance rates. Patients will be randomised into two groups; one group will receive a reminder phone call one week prior to their hospital consultation and the other group will be managed in the standard manner (i.e. no reminder of any sort). The phone calls will be carried out on a Friday afternoon by a respiratory nurse specialist and a research officer for two asthma clinics based on a Wednesday morning and a Thursday afternoon.

To have an 80% chance of detecting a 10% reduction in non-attendance rates (at 5%) 500 patients are required for this study. The rate of non-attendance will be monitored for all the patients in both groups and some demographic information will be recorded for each patient(age, sex, diagnosis and home postcode).
