Pressure ulcer development in patients treated for acute ischaemic stroke.

OBJECTIVE

The aim of this study was to determine the incidence of pressure ulcers (PUs) in patients treated for acute ischaemic stroke (AIS) and to evaluate comorbid/confounding factors.

METHOD: The study included patients treated for AIS who were divided into three treatment groups: those receiving intravenous tissue plasminogen activator therapy (tPA); patients receiving mechanical thrombectomy (MT); and those receiving both tPA and MT. PUs were classified according to the international classification system and factors that may influence their development were investigated.

RESULTS

A total of 242 patients were included in this study. The incidence of PUs in patients treated for AIS was 7.4%. Most PUs were located on the sacrum (3.7%), followed by the gluteus (3.3%) and trochanter (2.9%). With regards to PU classification: 29% were stage I; 34% were stage II; and the remainder were stage III. Age was not a significant factor in the development of PUs (p=0.172). Patients in the tPA group had a lower PU incidence (2.3%) than patients in the tPA+MT group (15.7%) and MT group (12.1%) (p=0.001). Patients with PUs had a longer period of hospitalisation (18.5±11.92 days) than patients without a PU (8.0±8.52 days) (p=0.000). National Institute of Health Stroke Scale (NIHSS) scores at admission were higher in patients with PUs than in patients without a PU (14.33±4.38 versus 11.08±5.68, respectively; p=0.010). The difference in presence of comorbidities between patients with and without PUs (p=0.922) and between treatment groups (p=0.677) were not statistically significant. The incidence of PUs was higher in patients requiring intensive care, but this difference was not statistically significant (p=0.089).

CONCLUSION

In this study, patients treated for AIS with high NIHSS scores at admission and/or receiving MT were at higher risk for PUs, and so particular attention should be given to these patients in order to prevent PU development.
