PURPOSE: To determine the prevalence and causes of pleural effusions in inpatients and outpatients evaluated at a tertiary care hospital.

METHODS: We reviewed 300 consecutive patients from our pleural fluid database at MUSC from 2001 to 2003, who had complete pleural fluid analysis. Age, gender, and patient location were documented.

RESULTS: 223(74%) of the 300 were inpatients and 77(26%) outpatients. Of the inpatients, 153(69%) were exudates and 70(31%) transudates. The most common diagnoses in inpatient exudates were malignancy/paramalignant 59(39%) and parapneumonic/empyema 43(29%). Lung 14(32%), breast 8(18%), and lymphoma 5(11%) were the most common malignancies. The most common inpatient transudate was congestive heart failure(CHF) 41(59%), followed by hepatic hydrothorax 17(24%). 67(87%) of 77 outpatients were exudates and 10(13%) were transudates. Malignancy/paramalignant effusions were the most common outpatient exudates 27(40%), followed by non-malignant chylothorax 10(15%). 4(40%) of 10 outpatient transudates were trapped lung and 2(20%) CHF. Of 153 inpatient exudates, 82(56%) were <60 years of age; these effusions were most commonly malignant/paramalignant 33(40%) and parapneumonic/empyema 20(30%). Of 71 inpatient exudates ≥60 years, 27(38%) were malignant/paramalignant and 17(24%) were parapneumonic/empyema. In inpatient females, 38(50%) of 76 exudates were malignant/paramalignant, and 17(22%) were parapneumonic/empyema; in males 28(35%) of 80 exudates were parapneumonic/empyema and 25(31%) were malignant/paramalignant. In outpatient females 15(50%) of 30 exudates were malignant/paramalignant, and 5(17%) were chylothorax; in males 15(50%) of 30 were malignant/paramalignant and 4(13%) chylothorax.

CONCLUSION: Malignant/paramalignant effusions represent the most common exudates in both inpatients and outpatients at a tertiary care university hospital. Furthermore, they were the most common exudates in <60 years of age. Malignant/paramalignant effusions were more frequently seen in females and parapneumonic effusions/empyema in males. CHF was the most common transudate in inpatients and trapped lung in outpatients.

CLINICAL IMPLICATIONS: Effusions due to malignancy are highly prevalent in both inpatients and outpatients, even in patients <60 years of age. Patients with malignant/paramalignant effusions may be seen in any age group and are often referred to tertiary care centers that offer expertise in diagnosis and management of malignancies.
