Importance of a comprehensive geriatric assessment in prediction of complications following thoracic surgery in elderly patients.
BACKGROUND The prevalence of comorbidities and functional impairment among elderly patients may enhance the risk of operation-related complications , but the importance of these conditions in elderly patients undergoing thoracic surgery remains unclear . METHODS One hundred twenty patients > /= 60 years of age who underwent thoracic surgery  were registered prospect ively and examined . A comprehensive geriatric assessment ( CGA ) that evaluated such diverse areas as functional status ( ie , performance status and activities of daily living [ ADLs ] using the Barthel index ) , comorbidity , nutrition ( ie , body mass index , arm-muscle circumference , albumin level , transferrin level , lymphocyte count , and cholinesterase level ) , and cognitive function ( ie ,  mini-mental state examination [ MMSE ] and negative emotions for operation )  was performed in the 2 weeks before patients underwent the operation . RESULTS The diseases of the 120 patients were as follows : lung cancer , 85 patients ; mediastinal tumor , 14 patients ; bullas , 12 patients ; and other diseases , 9 patients .  Postoperative complications developed in 20 patients ( 16.7 % ) . The patients with dependence for performing the ADLs , and dementia were more likely to develop postoperative complications ( p = 0.041 , and p = 0.0065 , respectively ) . The patients who experienced longer operation times ( ie , > /= 300 min ; p = 0.018 ) were more likely to have complications . The incidence of prolonged air leak in the patients with malnutrition increased seven-fold ( p = 0.045 ) and that of postoperative infectious diseases in those patients with obesity increased 24-fold ( p = 0.0013 ) , while all patients who developed delirium had low scores in the MMSE preoperatively ( p = 0.0003 ) . Using multiple logistic regression , the best model was obtained with a combination of MMSE ( p = 0.031 ) and the Barthel index ( p = 0.04 ) . When the operation variables were added to this model , the operation time had the strongest effect ( p = 0.016 ) . CONCLUSIONS Dependence for the performance of ADLs and impaired cognitive conditions are important predictors of postoperative complications , especially when the operation time is long . CGA is necessary in addition to the conventional cardiopulmonary functional assessment in elderly patients
