Patients who undergo surgery for lung cancer experience a variety of symptoms, such as pain and coughing, which interfere with their postoperative daily functions. However, there may be differences between the perception of symptoms among healthcare providers and patients. This study aimed to investigate patients' experiences after lung cancer surgery and analyze whether the perception of postoperative symptoms among the healthcare providers differed from that reported by patients.Semi-structured qualitative interviews involving 39 patients who underwent lung cancer surgery at the Sichuan Cancer Hospital were conducted between November 2018 and October 2019. In addition, 22 healthcare providers from the Department of Thoracic Surgery at the hospital answered open-ended questions about their perception of symptoms related to lung cancer surgery. The types and frequencies of symptoms reported by the patients and healthcare providers were compared.The most frequent patient-reported symptoms were pain (967 times, 39 patients, 100%), coughing (904 times, 37 patients, 94.87%), shortness of breath (491 times, 35 patients, 89.74%), Disturbed sleep (412 times, 34 patients, 87.18%), and interference while walking (347 times, 36 patients, 92.31%). Of the patient-reported symptoms, the first four were perceived by the healthcare providers, while they interpreted interference while walking as fatigue.Although the healthcare providers and patients had a certain consensus on the main symptoms, there were differences in perception. Healthcare providers need to pay more attention to postoperative interference while walking.© 2021. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
