Each year, more than million people in the United States develop pressure ulcers.  In acute care settings in the United States, the incidence of bedsores is % to 38%; within long-term care it is % to %, and in home care, it is 0% to 17%. Similarly, there is wide variation in prevalence : 10% to 18% in acute care, % to 28% in long-term care, and 0% to 29% in home care. There is a much higher rate of bedsores in intensive care units because of immunocompromised individuals, with 8% to 40% of those in the ICU developing bedsores.  However, pressure ulcer prevalence is highly dependent on the methodology used to collect the data. Using the European Pressure Ulcer Advisory Panel (EPUAP) methodology there are similar figures for pressure ulcers in acutely sick people in the hospital. There are differences across countries, but using this methodology pressure ulcer prevalence in Europe was consistently high, from % (Italy) to % (Sweden).  A recent study in Jordan also showed a figure in this range.  Some research shows differences in pressure-ulcer detection among white and black residents in nursing homes.
