Abstract

Background: Mortality from multidrug-resistant Acinetobacter baumannii is a crucial health crisis international. At present we do not have any simplified screening tools to forecast the risk of mortality related with multidrug-resistant A. baumannii infection.

Objectives: The objective of this study was to develop a screening tool to forecast mortality in participants with multidrug-resistant A. baumannii infection in Phrae Hospital.

Methods: A retrospective cohort study was conducted by collecting data from electronic database in Phrae Hospital period from October 1st, 2017 to March 31st, 2021. Univariable and multivariable logistic regressions were used to identify potential risk factors. The regression coefficients were transformed into item scores and added up to a total score. The prediction power of the model was determined by the area under the receiver operating characteristic curve (AuROC) and goodness-of-fit. The scoring scheme was applied in validation cohort to test the performance.

Results: Six clinical risk factors, namely immunocompromise host, chronic obstructive pulmonary disease, intensive care unit admission, patients who on Endotracheal tube, septic shock, and use of antibiotics within the past 3 months. The model showed good power of prediction (AuROC 76.21%). The positive likelihood ratio of low risk and high risk were 1.50 (95%CI: 1.27-1.77) and 4.50 (95%CI: 2.65-7.66), respectively.

Conclusion: The screening tool with six risk predictors provided a useful prediction index for mortality in participants with multidrug-resistant A. baumannii infection. However, further external validation of the tool is warranted prior to its utilization in routine clinical practice.
