All devices in Sweden that perform ultrasound exams for maternity dating purposes had been expected to accomplish a web-based questionnaire. Healthcare in Sweden is administered in 21 counties, and contact information for the ultrasound devices had been discovered through each county’s official website or through individual associates.
The questionnaire included 30 question things split into four proportions: 1) baseline information on the responder in addition to device; 2) the unit’s present medical training for maternity dating; 3) former training and modifications with time; and 4) evaluation associated with the precision associated with calculated gestational age and exactly how discrepancies involving the last-menstrual-period- and ultrasound-based techniques were managed. Concerns and replies had been printed in Swedish (a translated copy associated with the questionnaire is present on demand). The questionnaire comprised primarily multiple-response questions but included commentary areas. The quoted reviews have already been translated into English.
The questionnaire had been piloted among three other obstetricians and, after changes, had been distributed from a platform that is web-based.
