Prone position pressure sores in the COVID-19 pandemic: The Madrid experience.

BACKGROUND

In the context of the COVID-19 pandemic, prone position (PP) has been frequently used in the intensive care units to improve the prognosis in patients with respiratory distress. However, turning patients to prone imply important complications such as pressure ulcers. The aim of this paper is to describe the prevalence and characteristics of prone-positioning pressure sores (PPPS) and analyze the related risk factors.

METHODS

A case-control study was performed in Gregorio Maranon hospital in Madrid during the COVID-19 pandemic between April and May 2020. We enrolled 74 confirmed COVID-19 patients in critical care units with invasive mechanical ventilation who were treated with pronation therapy. There were 57 cases and 17 controls. Demographic data, pronation maneuver characteristics and PPPS features were analyzed.

RESULTS

In the case group, a total number of 136 PPPS were recorded. The face was the most affected region (69%). Regarding the severity, stage II was the most frequent. The main variables associated with an increased risk of PPPS were the total number of days under pronation cycles, and PP maintained for more than 24 h. The prealbumin level at admission was significantly lower in the case group. All of the ulcers were treated with dressings. The most frequent acute complication was bleeding (5%).

CONCLUSIONS

According to our study, PPPS are related to the characteristics of the maneuver and the previous nutritional state. The implementation of improved positioning protocols may enhance results in critical patient caring, to avoid the scars and social stigma that these injuries entail.
