What are the factors that cause pressure ulcers in our ICU. The list examines all patients admitted to our ICU from 01/01/2019 to 31/12/2019 with age >18 years who remained at least 72 hours, without pressure ulcers on admission. the first two columns contain the patient ID Column C gender Column D Days in ICU Column F Diabetes Col G Ulcer on admission Col H Patients who developed lesions during hospital stay Col I Day of hospitalisation when ulcer appeared J area of body where lesion developed K stage of lesion found L patient's age M Weight in Kg of patient N Height in Metres of patientw O Body Mass Index Columns P to U type of admission Column W to Z comorbidities present on patient Column AA days of Amine administration (norepinephrine, epinephrine or dobutamine) Column AB days of administration of Midazolam Column AC days of administration of Propofol Col AD days of administration of Rocuronium Col AE AF AG describe feeding AE Whether administered or not AF How many days it was administered AG The percentage of feeding days out of the total number of days of hospitalisation. Feeding was only considered effective if at least 15Kcal /kg/24h was administered Column AH if the patient had dialysis Column AI how many days the patient was connected by orotracheal tube to the ventilator Column AJ the percentage of days of invasive ventilation out of the total number of days of hospitalisation. Column AK value of SAPS II on admission Column AL value of albumin on admission Column AM Haemoglobin value on admission Column AN Blood Sodium value on admission Column AO Haemoglobin value on day 7 of admission Column AP Blood sodium value on day 7 of hospitalisation Column AQ Haemoglobin value on day 14 of hospitalisation Column AR Blood sodium value at day 14 of hospitalisation The data were collected during the 2020s by analysing the computerised medical records via Dragher's Innovian softwere by the ward nursing staff. The second word file shows the statistical analysis of the data, which were compared in relation to the occurrence of pressure ulcers by means of univariate and multivariate analysis. The data show that age, length of stay, dialysis, vasopressors, SAPS II and the presence of albumin were the most influential risk factors for the development of pressure ulcers in our intensive care unit.


Steps to reproduce

The data were collected by analysing the medical records of patients admitted in 2019 retrospectively during 2020. The data were stored on the Innovian® softwere owned by our intensive care unit and developed by Dräger. During the described period, 256 medical records were evaluated. All recorded variables were analysed using the appropriate statistics (frequency, mean, standard deviation, median, range and percentiles). The statistical relationship between the different factors and the outcome (occurrence of injury) was studied by means of the chi-square test, the t-test for independent groups and the Kruskal-Wallis test as a non-parametric method, depending on the type of variable under study. Variables that were significantly associated with the outcome in the univariate analysis were evaluated within a univariate logistic regression model to check for confounding factors. The results are presented in terms of odds ratios (OR) with relative 95% confidence intervals. For all statistical tests, the significance threshold was 0.05. The analysis was performed with the statistical software STATA 14.2.
