To compare a traditional telephone screening method to an enhanced voice recognition software system via a web based platform.
Subject data was extracted retrospectively from telephone screening documents from two investigational smoking cessation studies. Comparison was made of duration of time from the first subject telephone contact to date of on-site screening under the two telephone screening conditions.
360 subjects responded to advertisement for a smoking cessation study from October 2002 to March 2003. 181 subjects were excluded. Prior to Jan 20th 2003 and implementation of the new system, the average time lapse for 60 subjects between the initial response to the advertisement and the date the subject was actually seen at the site for screening and informed consent was 12.6 days. Following the implementation of the software system, 60 subjects were seen an average of 9.7 days between the time of response to the advertisement and the time seen for screening. Although this is not statistically significant, the system has reduced, by 25%, the number of days a potential subject makes contact with the site and the consent form is signed.CONCLUSIONS: The enhanced voice recognition software and the ability to rapidly extract the subjects that respond positively to the critical inclusion/exclusion criteria have reduced the amount of time (required by study personnel) between response to the advertisement and the time the subject is actually screened at the study site. It also drastically reduces the number of attempts to re-contact the individuals who are not available or an answering machine is reached at the initial effort to contact the potential subject thus averting the proverbial “phone tag” phenomenon.
Voice response systems may improve accrual rates for smoking cessation programs.
