Variables recorded: clinical characteristics, pleural fluid features, risk categorization for a poor outcome in patients with parapneumonic effusions and empyema, surgical treatment as outcome and its associated risk factors.Results217 patients were included, of these 52 (24%) had parapeumonic effusion and 165 (76%) had empyema. 163 (75.11%) were men, 72 (33.17%) had diabetes. 100 cases (46%) had two or more loculations, 32 of these cases did not proceed to surgical treatment. 116 (53.45%) were risk category 4 and 105 (48.38%) required surgical treatment.Mutivariate analysis revealed an increasing likelihood for surgical treatment with two or more loculations OR 2.94(IC 95% 1.54-5.63 p=0.001), more than 12000 leukocytes RM 2.30(IC 95% 1.23-4.31 p=0.009), diabetes RM 2.23(IC 95% 1.12–4.46 p=0.023), risk categorization for a poor outcome in empyema RM 9.59(IC 95% 1.12–8.23 p=0.000) and age RM 0.98(IC 95% 0.96–0.99 p=0.046).ConclusionsSurgical treatment decision is based on local protocols, institutional experience and individual case management with a flexible sequence of procedures.However, two or more loculations, risk categorization for a poor outcome in parapneumonic effusion and empyema, diabetes and leukocytosis are good predictors for surgical treatment.
