Patterns of elective lobectomy for lung cancer

Abstract

BackgroundLobectomy is the recommended treatment for early-stage lung cancer. Little is known about variations of access to health service areas and hospital types for lobectomy overall and according to specific surgical techniques, such as the video-assisted thoracoscopic surgery (VATS). MethodsThe New York Statewide Planning and Research Cooperative System (2007-2012) was queried for lung cancer patients who underwent elective lobectomy. Hospitals were defined as nearest high-volume hospital (nHVH, reference), distant HVH (dHVH), close or distant low-volume hospital (cLVH or dLVH) using lobectomy volume and travel burden by the distance to nHVH. ResultsUtilization of hospitals within patients' health service areas ranged between 44% and 82% for three different geographic units. Approximately 26%, 34%, 31%, and 9% of the 9099 lobectomies were performed in nHVH, dHVH, cLVH, and dLVH, respectively. Patients in nHVH were older and more likely to have private insurance. Patients in dHVH were treated more with VATS and by higher volume surgeons, opposite of what observed in cLVH and dLVH. The use of dHVH was associated with more comorbidities and higher income. The use of dLVH was higher in Hispanics and non-Hispanic blacks than that in non-Hispanic whites. The odds of adverse postoperative events were higher in cLVH and dLVH but lower for patients treated with VATS and by high-volume surgeons. ConclusionsMultiple factors likely resulted in differences in patterns of elective lobectomy among lung cancer patients. These variations should be taken into account when accessing and planning specialized health care delivery services.
