Objective  The aim of this research was to compare the effectiveness of two mattresses used in intensive care unit (ICU) high-risk patients in terms of pressure ulcers (PUs) prevention and healing.  Materials and Methods  The studied sample consisted of 70 consecutive patients aged 18 to 65 years hospitalized in two ICUs of a general hospital in Athens, Greece. Virtuoso Mattress System (LINET, Slaný, Czech Republic) was used in 35 patients, and standard memory foam mattress was used in the rest of participants. Patients were firstly assessed on enrollment and then every 72 hours in order to record the appearance or not of PUs, location of PUs, and stage of PUs, with the maximum follow-up not exceeding the 21 days. A number of clinical and biochemical factors, medical treatment, and vital signs were also recorded at each time point.  Results  Of the 70 patients, 40 (57.1%) were men, and the mean ± standard deviation age of the sample was 46.1 ± 14.5 years. The most common area of PUs was the buttocks (34.3%) followed by the shoulders (22.3%), with no statistically significant difference detected between the two groups. Moreover, the proportion of patients having PUs at stage 2 or higher was 23.8% on the third day after admission and 61.1% on the sixth day, with no difference detected between the two groups. Cox proportional hazard model revealed that the Virtuoso mattress was associated with almost 56% lower risk of developing PUs compared with standard foam mattress (HR [95% CI]: 0.44 [0.20-0.93]). The percentage of patients healed using the Virtuoso mattress was significantly lower compared with the standard foam mattress at all time points, with the results reaching statistical significance only on the 12th day after admission (7.7% vs. 66.7%; p < 0.05).  Conclusions  The Virtuoso mattress seems to be more effective compared with standard foam mattresses in the prevention of PUs, whereas the standard foam mattresses are more effective in PU healing process.
