The overall project aim is to study risk and outcomes following thoracic surgery by cross-linking high-quality national Swedish health-data registers for population-based investigations of individual level clinically relevant patient data.

The purpose of this research project is to study risks and outcomes in patients who underwent thoracic surgery, primarily for lung cancer. We aim to establish a fundament for the conduct of nationwide population-based studies by linking patient-level data from the Swedish quality register for thoracic surgery (ThoR) and other national health-data registers maintained by the government agencies Statistics Sweden and the National Board of Health and Welfare. Cross-linking patient-level data is possible through the Personal Identity Number assigned to every individual who has resided in Sweden on a permanent basis. The Swedish Personal Identity Number is the unique identifier in all national registers.

Specifically, we aim:

1. To analyze the association between socioeconomic factors and prognosis in patients undergoing pulmonary resection for lung cancer.
2. To investigate the implementation of minimally invasive surgery for lung cancer in Sweden.

Inclusion Criteria:

Exclusion Criteria:

-

There is no plan to make individual participant data available to other researchers.
