Patient preferences regarding possible outcomes of lung resection: what outcomes should preoperative evaluations target?
BACKGROUND
Lung resection can lead to significant postoperative complications: Although many reports describe the likelihood of postoperative problems, such as atelectasis, pneumonia, and prolonged ventilator dependence, it is unclear whether patients perceive these outcomes as sufficiently severe to influence their decisions about surgery.


OBJECTIVE
To assess patients' preferences regarding possible outcomes of lung resection, including traditional complications reported in the lung surgery literature and outcomes that describe functional limitation.


METHODS
Utility analysis.


METHODS
A community hospital internal medicine clinic, a private internal medicine practice, and a private pulmonary practice.


METHODS
Sixty-four patients, aged 50 to 75 years, who were awaiting appointments at the designated clinic sites.


METHODS
Patients' strength of preference regarding potential outcomes of lung resection as derived from health utility scores.


RESULTS
Common postoperative complications were assigned high utility scores by patients. On a scale for which 1.0 represents perfect health and 0 represents death, postoperative atelectasis, pneumonia, and 3 days of mechanical ventilation were all rated >0.75. Scores describing limited physical function were strikingly low. Specifically, activity limited to bed to chair movement and the need for complete assistance with activities of daily living were all assigned utility scores <0.2. Twenty-four-hour oxygen dependence was scored at 0.33. Presence or absence of pulmonary illness did not predict scores for any outcome.


CONCLUSIONS
Whether patients suffer from chronic lung disease or not, they do not regard the postoperative outcomes reported in the lung surgery literature as sufficiently morbid to forego important surgery. However, physical debility is perceived as extremely undesirable, and anticipation of its occurrence could deter surgery. Therefore, identification of preoperative predictors of postoperative physical debility would be invaluable for counseling patients who face difficult decisions about lung resection.
