Standardized Prospective Intervention in Hospitalized Patients with Bacterial Pneumonia

Area of Science:

• Infectious Diseases
• Clinical Medicine
• Healthcare Management

Background:

• Community-acquired pneumonia (CAP) is a major global cause of infectious mortality.
• Variability in CAP diagnosis and management impacts patient outcomes.
• Standardized protocols aim to improve consistency and effectiveness in CAP care.

Purpose of the Study:

• To evaluate the impact of a standardized hospital protocol on clinical outcomes for bacterial CAP.
• To identify factors associated with in-hospital and 30-day mortality in CAP patients.
• To assess the association between protocol implementation and mortality rates.

Main Methods:

• An ambispective before-after study comparing pre-intervention (2019) and intervention (2022-2023) periods.
• Intervention involved a standardized CAP protocol, training, and a checklist.
• Analysis included mortality, length of stay, and antibiotic adequacy; logistic regression identified mortality factors.

Main Results:

• Hospital mortality decreased from 16.6% to 11.3% post-protocol implementation (p=0.002).
• Median length of stay showed a slight reduction (8.1 to 7.9 days; p<0.001).
• Factors associated with in-hospital mortality included therapeutic effort limitation and low SaO2/FiO2; 30-day mortality linked to ARDS, low SaO2/FiO2, age, and low Barthel Index.

Conclusions:

• A standardized CAP protocol implementation correlated with reduced mortality and improved antibiotic adequacy.
• Findings support protocol-driven, multidisciplinary strategies for strengthening CAP management.
• Periodic audit and feedback cycles are recommended for continuous improvement in CAP care.
