Age-Related Differences in Clinical Outcomes of Patients with Pleural Empyema: A Retrospective Single-Center Study.

: Pleural empyema remains a serious clinical condition with high morbidity and mortality, especially in elderly patients. As life expectancy increases, a growing number of older individuals require surgical treatment. This retrospective single-center study investigated age-related differences in clinical presentation, perioperative features, and postoperative outcomes in patients undergoing surgery for pleural empyema. : We conducted this retrospective study at Helios University Hospital Wuppertal, Witten Herdecke University in Germany, from December 2019 to May 2024. We stratified the patients into two age groups: <65 and ≥65 years. We compared baseline characteristics, American Society of Anesthesiologists (ASA) physical status classification, empyema stage, hospital stay, drainage duration, complication rates, and in-hospital mortality. : A total of 103 patients were included, of whom 43 (41.7%) were aged ≥ 65 years. Older patients had significantly higher ASA scores and presented with more advanced empyema stages. Hospital stay was significantly longer in this group. However, complication rates (60.0% vs. 44.9%; = 0.25), drainage duration, ICU admissions (91.4% vs. 83.7%; = 0.48), and in-hospital mortality (0% in both groups) did not differ significantly. : Although older patients had higher perioperative risks, their surgical outcomes were similar to those of younger patients. Chronological age alone should not be a limiting factor for surgical treatment of pleural empyema. Surgical decisions should be based on clinical condition rather than chronological age.
