Development of a Nursing Risk Inventory and Evaluation of Efficiency in Transurethral Resection of the Prostate Syndrome.

Purpose: To develop a nursing risk assessment inventory and evaluate its effectiveness in transurethral resection of the prostate (TUR-P) syndrome.

Design: A cross-sectional methodological study using inventory development and verification phases.

Methods: A methodological research study within the scope of a PhD thesis was performed in 3 phases between December 2019 and September 2021 with 154 patients in the Urology Operating Room of Aydın Adnan Menderes University Hospital in Turkey. The first phase involved inventory development-according to expert opinions-and data collection. The second phase involved performing validity and reliability analyses. The third phase involved translation of the inventory from Turkish to English. TUR-P Syndrome Risk Evaluation Inventory, preoperative, postoperative period neurological, and circulatory features were examined in terms of TUR-P syndrome according to blood results at risk patients were identified. In content validity analysis, Fleiss' kappa statistic was performed according to Lawshe's technique that was used to study the construct validity.

Findings: Content and reliability analysis revealed that the nursing risk assessment inventory is a valid and reliable scale. The content validity ratio was determined as 0.81. According to the construct validity analysis, Wilk's lambda value was 0.77 (χ = 36.68, degree of freedom = 13, P = .001). Inventory risk score calculation formula was determined according to results from the discriminant analysis. The risk status of a patient for TUR-P syndrome can be decided according to the absolute value of the discriminant function. Reliability analysis based on expert opinions showed that Fleiss kappa value was k = 0.812 (z = 31.846, P = .00) and risk/no risk classification kappa value was k = 0.724 (z = 28.424, P = .00).

Conclusions: The nursing risk assessment inventory for TUR-P syndrome is a valid, reliable, and objective measurement tool. Using this 14-item inventory with 2 categories (7 items in the circulation and neurology scales each), nurses can evaluate the patient's risk status during TUR-P surgery and take postoperative precautions.
