Prenatal cystic fibrosis carrier testing: designing an information leaflet to meet the specific needs of the target population.

A questionnaire was given to 180 patients in an antenatal clinic, who were eligible to enter a pilot trial of cystic fibrosis (CF) carrier testing, seeking their views on the information leaflet inviting them to participate; 161 patients (89%) entered the trial and 145 patients (81%) responded to the questionnaire, including 10 who did not enter the trial. Ninety-six percent of these found the leaflet easy to understand, and 97% of those partners who read the leaflet also found it easy to understand. Fifteen percent of patients thought the leaflet should give additional information. Most (92%) had heard of CF before reading the leaflet, television being the most common source of information. Although avoiding the birth of a child with CF was the reason most patients gave for wishing to be screened, almost as many were interested to know their carrier status. The decision to accept or decline testing was taken in conjunction with their partner by 63% of women. Of those who were screened, 59% stated that taking the test made them feel reassured, while 38% felt slightly apprehensive. It was concluded that, with a number of minor amendments, the leaflet met the specific needs of the target patient population.
