Factors Affecting Cost of Patients with Severe Community-Acquired Pneumonia in Intensive Care Unit

OBJECTIVES: The aim of this study is to investigate the factors affecting cost in patients with severe community-acquired pneumonia (CAP) who were admitted to the intensive care unit (ICU).

MATERIALS AND METHODS: This retrospective cohort study was conducted between January 2013 and December 2016. A total of 291 sequential patients with severe CAP were included in the study. Patients’ demographic and clinical data; the need for invasive mechanical ventilation or non-invasive mechanical ventilation; intensive care severity (ICU) scores, including Acute Physiology and Chronic Health Evaluation (APACHE II), Sepsis-related Organ Failure Assessment, Quick SOFA, pneumonia severity index (PSI); and Confusion, Urea, Respiratory Rate, and Blood Pressure-65 (CURB-65) scores were obtained from medical records and recorded for all cases.

RESULTS: The mean age of 291 patients was 68.4±16.8 years, and 61% were female. The median length of ICU stay was 7 days. Forty-six percent of patients had chronic obstructive pulmonary disease (COPD), and 42% had hypertension. The mean cost of each hospitalization was US$ 2722 (TL 5578). The highest cost was found in the group of patients aged 50–59 years, and the lowest cost was found in the patients aged <50 years. A statistically significant relationship was found between ICU severity scores and health cost. The cost of patients in PSI class V, APACHE II (>20 points), and CURB-65 score were higher. The presence of COPD, atrial fibrillation, congestive heart failure, hypoalbuminemia, mental state deterioration, in-hospital mortality, severe sepsis, septic shock, mechanical ventilation requirement, and haloperidol and vasopressor usage were associated with higher cost, while the use of florokinolon was associated with lower cost.
 

CONCLUSION: The presence of certain comorbidities and high disease severity in patients with severe CAP hospitalized in ICU increase the cost of inpatient treatment. The need for mechanical ventilation during treatment and the presence of sepsis/septic shock are additional factors that increase the cost.
