When you call, ask what referral paperwork is required and whether a GP letter must arrive before the visit. Request the current fee schedule, including any charge for the sleep study itself and for reporting the results. Ask what kind of sleep study is offered, where it takes place, and whether you sleep there overnight. Ask whether appointment confirmations and any forms can be sent before the visit. Confirm the cancellation policy, since missed-appointment fees differ between clinics. 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. Confirm fees, availability and location directly with the practice, as directory listings are not updated in real time.
