Chronic heart failure in patients undergoing major head and neck surgery: A hospital-based study

Abstract

ObjectiveTo investigate the effects of chronic heart failure on various post-operative outcomes in head and neck cancer patients undergoing major cancer surgery. Study designFor this retrospective cohort study of patients undergoing major head and neck cancer surgery, a sample of 10,002 patients between 2017 and 2019 were identified through the Nationwide Inpatient Sample. SettingPatients were selected as undergoing major head and neck cancer surgery, defined as laryngectomy, pharyngectomy, glossectomy, neck dissection, mandibulectomy, and maxillectomy, then separated based on pre-surgical diagnosis of chronic heart failure. MethodsThe effects of pre-operative chronic heart failure on post-surgical outcomes in these patients were investigated by univariable and multivariable logistic regression using ICD-10 codes and SPSS. ResultsA diagnosis of chronic heart failure was observed in 265 patients (2.6 %). Patients with chronic heart failure had more preexisting comorbidities when compared to patients without chronic heart failure (mean ± SD; 4 ± 1 vs. 2 ± 1). Multivariable logistic regression showed that chronic heart failure patients had significantly greater odds of dying during hospitalization (OR 2.86, 95 % CI 1.38–5.91) and experiencing non-routine discharge from admission (OR 1.89, 95 % CI 1.41–2.54) after undergoing major head and neck cancer surgery. ConclusionChronic heart failure is associated with greater length of stay and hospital charges among head and neck cancer patients undergoing major head and neck cancer surgeries. Chronic heart failure patients have significantly greater rates of unfavorable post-operative outcomes, including death during hospitalization and non-routine discharge from admission.
