Photographic records and dressings
We obtained a total of 7446 baseline photographic-records (average of 10.8 per patient) from all body areas under study at baseline of the study and 6740 photographic-records of body areas at the end of the study (average of 9.7 per patient). One thousand three hundred and forty-four (1344) dressings were used to cover 312 supine patients, 72 were used to cover 18 prone patients, and 24 were used to cover seven lateral-position patients (lateral right or left). For each patient in the supine position, we used three HCDs of 15 × 15 cm and one HCD of 20 × 25 cm (a total of 3425 HCDs); for prone patients, we used four HCDs of 15 × 15 cm (a total of 180 HCDs); and for patients in position lateral position, we used four HCDs of 15 × 15 cm (total 42 HCDs). The areas that received MC were 3633 in the supine position, 100 in the prone position, and 66 in the lateral/SIM position, the same areas covered by dressings.
