Prevalence and Etiology of Pleural Effusions in Hospitalized Patients: An Analysis of HCUP-NIS 2012
Disorders of the Pleura SESSION TITLE: Pleural Disease SESSION TYPE: Original Investigation Poster PRESENTED ON: Wednesday, November 1, 2017 at 01:30 PM - 02:30 PM
Prevalence and Etiology of Pleural Effusions in Hospitalized Patients: An Analysis of HCUP-NIS 2012 Niloofar Taghizadeh* Marc Fortin Benjamin Shieh and Alain Tremblay Division of Respiratory Medicine and Charbonneau Cancer Research Institute, University of Calgary, Calgary, AB, Canada PURPOSE: Pleural effusions are a common problem associated with a multitude of other conditions. The prevalence and etiology of pleural effusions have not been examined on a population level. METHODS: We conducted a retrospective analysis of pleural effusion associated hospitalizations using the Healthcare Cost and Utilization Project -Nationwide Inpatient Sample, Agency for Healthcare Research and Quality (HCUP-NIS 2012). Cases were included if a specific type of pleural effusion was coded, or an unspecified pleural effusion coded in addition to diagnosis of congestive heart failure, kidney failure, infection, malignancy, pulmonary embolism, and any other major conditions associated with pleural effusion, with either of these being the primary diagnosis. Descriptive analyses were used to report the characteristics of pleural effusion hospitalizations.
CONCLUSIONS: Pleural effusions are found in 2% of hospitalized patients, most often in association with renal failure, CHF, infection or malignancy. CLINICAL IMPLICATIONS: These national estimates provide strong population based information on the prevalence and etiology of pleural effusions not previously available. Additional work is warranted to determine the attributable impact of these effusions on outcomes and costs.

DISORDERS OF THE PLEURA
RESULTS: A weighted sample of 751,150 (2%) admissions associated with pleural effusion were identified among the 36,484,846 weighted admissions included in the database in 2012. Of these admissions, 385,670 (51.3%) were for female patients. The median (interquartile range (IQR)) age at admission was 69.4 years (57.1-80.5). Renal failure (33.6%), pneumonia/empyema (32.0%), congestive heart failure (CHF) (26.7%), malignancy (16.9%), cirrhosis (9.4%), pulmonary embolus (3.3%), peritonitis and intestinal abscess (2.4%), and pancreatitis (2.3%) were the most common diseases associated with pleural effusion. In 14% of cases, both renal failure and CHF were noted. The median (IQR) length of stay was 6.4 (3.3-11.7) days and the inpatient mortality rate was 8.5%. Median (IQR) hospitalization total charges were US $48,278 (23.693-105,076).
