Bedsores (NDNQI)

A bedsore is also known as a pressure sore or pressure ulcer. A bedsore is an area of skin injury or breakdown that can occur when people lie in one position for an extended period of time – as little as a few hours - without shifting positions. These wounds are not only uncomfortable, but they can also become infected, leading to further complications. If identified early, many bedsores can be successfully treated to avoid complication.

Not all bedsores can be prevented, but many can, so it’s important for hospital staff to make sure that bedridden patients are moved or turned regularly. While some patients have higher risks than others, some of these complications may be preventable. A lower rate may indicate that a hospital provides a higher level of patient care.

About this measure

This measure tracks the number of patients who were identified with bedsores based on a systematic review of all patients in the hospital on a given date (a “prevalence” study) each quarter.

Please note:  NDNQI database is proprietary and we cannot display the comparison data, but we receive reports quarterly which indicate how our hospital compares to the database. 

That comparison is expressed as "observed" vs. "expected." The pressure ulcer rate for this measure is expressed as the observed (actual) rate of pressure ulcers compared to the expected rate of pressure ulcers. A value of 1.0 would mean that the rate of pressure ulcers was exactly as expected. A rate higher than 1.0 means that the rate was higher (worse) than expected, and a rate below 1.0 means that the rate was lower (better) than expected. In some quarters, our observed rate was below 1.0, or better than expected, and in some quarters, our observed rate was above 1.0, or worse than expected.

Note: In this case, a lower number is better.
