Cancer-related ED visit | patients whose visit was unambiguously related to their cancer, i.e. who visited the ER due to the complications or progression of their cancer |
Oncological care-related ED visit | patients with cancer whose visit was due to the complications/adverse events of some form of oncological care they had received prior and nearest to the ER visit |
New cancer diagnosis-related ED visit | cases where a strong suspicion of cancer arose at the given ER visit, which diagnosis was subsequently confirmed |
Non-cancer related ED visit | patients whose visit to the ER was in no way associated with their cancer illness |
Undetermined ED visit | patients whose medical condition could be a result of either the complication/progression of their cancer or due to completely other causes (e.g. pneumonia in a patient with lung cancer and advanced COPD could be due to either of the latter two illnesses) |
