Actigraphy can be used to Quantify Sleep in the Perioperative Period in Women Undergoing Breast Cancer Surgery: A Validation Study
Background: Sleep disturbances after surgery are frequent and a valid tool to quantify these is warranted. We set out to make an epoch by epoch validation of actigraphy against polysomnography (PSG) for detection of sleep and wake in women undergoing surgery for breast cancer. Methods: Twelve patients, 30-70 years, undergoing a lumpectomy were included. Patients simultaneously wore an actigraph and a polysomnograph on the preoperative night (PREOP), the first postoperative night (PO1), and the fourteenth postoperative night (PO14). The outcome measures were sensitivity (i.e. the amount of correctly scored sleep) and specificity (i.e. the amount of correctly scored wake).
