Ask the practice whether you need a referral from a GP before the first appointment. Ask what is billed separately, such as the study, the report, or a follow-up appointment. Ask which sleep study the practice would use — home testing or an overnight study in a lab — and what each involves. Ask whether appointment confirmations and any forms can be sent before the visit. Ask what to bring: a medication list, any referral letter, a sleep diary, and results from earlier studies. It is worth asking whether the practice deals with the kind of sleep problem you have, since some clinics focus on particular conditions. Find out whether the practice runs a structured sleep program and how many sessions it involves. Because listing data can lag behind the practice, check the essentials by phone before booking.
