Abstract
To verify the effectiveness of the educational intervention through the evaluation of nurses' knowledge about prevention of pressure injury. A quasi-experimental study with a single group, carried out with 95 nurses from a teaching hospital in the interior of Minas Gerais, in August and September 2017. As a teaching strategy, the active methodology and hybrid teaching were used, based on the reference of the Method of the Arch of Charles Maguerez. Data were collected from a validated instrument, called the Pieper Knowledge Test, and analyzed by descriptive statistics and Student's t-test with significance level of p <0.001. The mean number of correct answers obtained by the nurses was 78.8% in the pre-test and 88.8% in the post-test, and the difference was statistically significant (p <0.001). The educational intervention developed was effective, since it contributed to the improvement of nurses' knowledge.
Highlights
Pressure ulcers (PU) are one of the main adverse events found in health services, being one of the most common consequences of long stay in hospitals[1]
When considering the average of right answers before the intervention and the professional’s training, those having only graduation reached an average of 76.6% right answers; those with specialization, and average of 79.7% right answers; masters, an average of 76.1%; and doctors, an average of 73.2%
In relation to the average of right answers, the nurses who have another job reached a score of 81% in the pre-intervention test and, after the training, it increased to 89.7%
Summary
Pressure ulcers (PU) are one of the main adverse events found in health services, being one of the most common consequences of long stay in hospitals[1]. Its occurrence is associated with care failures, and with the factors inherent in the individual cared for, which increases the risks of developing the injury[3]. A study[4] carried out in a university hospital with 77 patients admitted to the intensive care unit (ICU) pointed that the incidence of PU was 22%. Other studies[5,6] showed incidence of PU ranging from 25.8% to 50%. The high incidence is directly related to the patients’ high risk of developing the PU, according to the Braden scale[7], and the first week of hospitalization is the period in which most of the injuries arise[8]
