A stop-smoking telephone help line that nobody called.

The purpose of this study was to evaluate the reach of a smoker's hotline that provided a variety of services to over 2100 health maintenance organization members. Formative evaluation procedures identified topics of concern, and repeated promotions advertised the service via multiple channels. Excluding a special giveaway promotion, an average of less than three calls per month were made during the 33 months of operation. To be cost-effective, smoker's hotlines should be offered to large populations and should be consistently and intensively publicized.
