OBJECTIVES: Patients with pleural infections frequently have several comorbidities and inferior long-term survival. We hypothesized that these patients represent a vulnerable cohort with high rates of hospitalization and frequent use of healthcare services. This study aims to ascertain the need for and causes of treatment episodes after pleural infections during long-term follow-up. METHODS: Patients treated for pleural infections at Tampere University Hospital between January 2000 and December 2008 (n = 191, 81% males, median age 58 years) were included and compared to a demographically matched population-based random sample of 1910 controls. Seventy percent of the pleural infections were caused by pneumonias and 80% of the patients underwent surgery. Information regarding later in-hospital periods and emergency room and out-patient clinic visits, as well as survival data, was obtained from national registries and compared between patients and controls. RESULTS: Patients treated for pleural infections had significantly higher rates of hospitalizations (8.19 vs 2.19), in-hospital days (88.5 vs 26.6), emergency room admissions (3.18 vs 1.45), out-patient clinic visits (41.1 vs 11.8) and procedures performed (1.26 vs 0.55) per 100 patient-months when compared to controls during 5-year follow-up, in addition to having increased mortality (30% vs 11%), P-value <0.00001 each. Particularly, episodes due to respiratory and digestive diseases, malignancies and mental disorders were more frequent. The patients' comorbidities, such as alcoholism or chronic pulmonary disease, were associated with more frequent use of healthcare services. CONCLUSIONS: Patients treated for pleural infections have high rates of hospitalizations, emergency room admissions and out-patient clinic visits during follow-up.
