Opinions of lung cancer clinicians on shared decision making in early-stage non-small-cell lung cancer

Abstract

OBJECTIVES: To investigate the opinions of lung cancer clinicians concerning shared decision making (SDM) in early-stage non-small-cell lung cancer patients. METHODS: A survey was conducted among Dutch cardiothoracic surgeons and lung surgeons, pulmonologists and radiation oncologists. The opinions of clinicians on the involvement of patients in treatment decision making was assessed using a 1-5 Likert-type scale. Through open questions, we queried barriers to and drivers of SDM in clinical practice. Clinicians were asked to review 7 hypothetical cases and indicate which treatment strategy they would choose using a 1-7 Likert-type scale. RESULTS: Twenty-six percent of surgeons, 20% of pulmonologists and 12% of radiation oncologists indicated that they always engage in SDM (16% missing; P-value = 0.10). Most respondents stated that, ideally, doctors and patients should decide together (surgeons 52%, pulmonologists 67% and radiation oncologists 35%; P-value = 0.005). Thirty percent of surgeons, 27% of pulmonologists and 44% of radiation oncologists indicated that doctors are not properly trained to implement SDM in clinical practice (P-value = 0.37). SDM may not always be feasible due to low patient education level and minimal knowledge about lung cancer. Wide variations in the clinicians' lung cancer treatment preferences were observed in the responses to the hypothetical cases. CONCLUSIONS: In current clinical decision making in lung cancer treatment, a majority of clinicians agree that it is important to involve lung cancer patients in treatment decision making but that time constraints and the inability of some patients to make a weighted decision are important barriers. The observed variation in lung cancer treatment preferences among clinicians suggests that for most patients both surgery and radiotherapy are suitable options, and it underlines the sensitive nature of treatment choices in early-stage non-small-cell lung cancer.
