OP45 Study On Effects Of Community-acquired Pneumonia Clinical Pathway On Antibiotics’ Utilization

Abstract

INTRODUCTION:

Drug overuse in healthcare settings is common in China. Clinical pathways are tools that provide the link between the best available evidence and clinical practice. This study aimed to determine if the clinical pathway of community-acquired pneumonia (CAP) had effects on the antibiotic use in patients with CAP.

METHODS:

The study was conducted in Shanghai, Hubei Province, and Gansu Province to represent high, middle, and low levels of socioeconomic status in 2015. In each region, three public tertiary general hospitals and three public secondary general hospitals were selected for chart review of antibiotics’ utilization in the patients with CAP during 2014. A multilevel logistic regression model was used in the study, with a dependent variable of appropriate utilization of antibiotics (right time, right type, and right combined use) and independent variables of hospital adoption of clinical pathway and patient characteristics (sex, age, severity of disease, and number of comorbidities).

RESULTS:

Twelve surveyed hospitals (66.67 percent) adopted CAP clinical pathways and 354 cases (66.29 percent) were from these twelve hospitals (CP group). Among the total utilization of antibiotics (796 times) in eighteen types of antibiotics used in patients with CAP, the five recommended types of antibiotics accounted for 82.16 percent.

The percentages of cases that got initial antibiotics in time were 90.60 percent in the CP group and 76.11 percent in the non-CP group. The compliance rate for appropriate types of antibiotic utilization was 88.36 percent in CP group, much higher than that in non-CP group (70.22 percent). For 244 cases that used combined antibiotics, the compliance rate for the recommended combinations of antibiotics was 20.12 percent in the CP group, but 1.25 percent in the non-CP group. After controlling patients’ characteristics, the patients in the CP group got more appropriate antibiotics than those in the non-CP group.

CONCLUSIONS:

Adoption of the CAP clinical pathway in hospitals can improve antibiotics' utilization.
