Predictive and Protective Factors Related to the Occurrence of Pressure Injuries Among Critically-ill Surgery Patients: A Retrospective, Case-Control Study

Critically-ill surgical patients are at risk for developing pressure injuries. This retrospective, case-control design study was aimed to explore predictive and protective factors associated with the occurrence of pressure injuries among critically-ill surgical patients. The data of 285 critically-ill surgical patients were collected between 2015 and 2020 in a hospital in Ubon Ratchathani Province, Thailand. They were purposively recruited based on having (n = 95), or not having (n = 190), a pressure injury. The data were collected using the Factors Related to the Occurrence of Pressure Injury Record Form. The instrument’s content validity was approved by three clinical experts and its content validity index was 1.0. Data were analyzed using descriptive statistics and multiple logistic regressions. Results showed that most of the participants were male (61.8%) with an average age of 65.83 years (SD =14.53). The predictive factor of developing a pressure injury was higher Body Mass Indexes (BMI). Those who had higher BMI were at 1.37 times (OR = 1.37, 95 % Cl [1.06, 1.77]) greater risk for developing a pressure injury than those who had a normal BMI. It also revealed that moisture (OR = 0.51, 95 % Cl [0.27, 0.98]), mobility (OR = 0.11, 95 % Cl [ 0.04, 0.25]), and friction or shearing (OR = 0.42, 95 % Cl [0.19, 0.91]) were protective factors preventing pressure injuries. When the score for any one of these three factors increase 1 point, the potential to develop a pressure injury is likely to decrease. Therefore, care for critically-ill surgical patients with a high BMI, decreasing level of consciousness, immobilization, and having moist skin or poor skin sensation should be more focus.
