Review of risk factors and prediction models for multidrug-resistant bacterial pulmonary infections in patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease is a prevalent chronic respiratory disorder that often coexists with multidrug-resistant bacterial infections in the lungs, significantly increasing treatment complexity and patient mortality. Consequently, research on the prevention and management of chronic obstructive pulmonary disease complicated by pulmonary multidrug-resistant bacterial infections has attracted increasing attention. Establishing predictive models for chronic obstructive pulmonary disease complicated by multidrug-resistant bacterial infections based on clinical risk factors has become a crucial direction in current clinical research. This narrative review summarizes the limitations of currently available predictive models, particularly in the selection of major risk factors and model construction. It aims to provide guidance for the selection and optimization of future predictive model development methods. The goal is to enhance the predictive performance and clinical applicability of these models while laying a theoretical foundation for the transformation of diagnostic and therapeutic paradigms.
