O052 Patient Preference and Acceptability of Sleep Diagnostic Tests during early Pregnancy

INTRODUCTION: A range of test options are available to diagnose OSA. Test acceptability is measured via successful completion, though this fails to capture the patient preference. There is a paucity of data on acceptability particularly in pregnancy. We thus developed questionnaires to assess test preference and acceptability of Apnealink-Air, Somte and Grael tests, in pregnancy till 24 weeks gestation. METHODS: Eighty-four pregnant women by 24 weeks gestation were invited to complete home Apnealink-Air, unattended-self-applied-Somte-PSG and attended-Grael-PSG. Questionnaires were beta-tested by hospital staff (unaffiliated with study). Using a 5-point Likert scale, questionnaires assessed ease of use, convenience and acceptability of repeating test. A ranking scale was used to determine test preference. Following completion of tests, participants completed questionnaires. RESULTS: Of 59 participants that completed any test, 35 completed any questionnaire (Apnealink(n=33), Somte(n=33), Grael(n=30), preferred test (n=29)). Ranking of test preference demonstrated Apnealink ranked 1st/72.4%, Grael 2nd/20.7% and Somte 3rd/6.9%. Apnealink, Somte and Grael questionnaire data responses were assessed for ease of use (very easy (51.6%), easy / neutral (34.4/34.4%) and very easy (33.3%) respectively), convenience (very convenient (51.6%)), neutral (36.7%) and convenient (50%) respectively), and acceptability to repeat test (very acceptable (41.9%), neutral (43.3%) and neutral(43.3%)), respectively. DISCUSSION: Pregnant women being assessed for OSA by 24 weeks gestation preferred Apnealink to Somte and Grael PSG. Participants reported Apnealink easiest to use, most convenient and most acceptable to repeat in a future pregnancy. Patient autonomy is an important principle; womens’ preferences should be taken into consideration in clinical sleep services and research.
