Abstract

Total hip and knee arthroplasties are two of the most quality of life enhancing orthopedic procedures performed. Enhanced recovery (ER) programs have been implemented in orthopedic surgery and have helped optimize preoperative, perioperative, and postoperative factors to reduce the physiological and psychological stress of surgery. The American Society of Anesthesiologists [ASA] classification system is now the most widely collected system for measuring physical health status by hip and knee arthroplasty registries worldwide. The aim of the study is to determine whether the ASA score is a predictive of length of hospital stay in patients undergoing hip and knee surgeries in elective setting.

American Society of Anaesthesiologists physical status classification

Mohamed Daabiss (2011)

Although the American Society of Anaesthesiologists’ (ASA) classification of Physical Health is a widely used grading system for preoperative health of the surgical patients, multiple variations were observed between individual anaesthetist’s assessments when describing common clinical problems. This article reviews the current knowledge and evaluation regarding ASA Classification of Physical Health as well as trials for possible modification.

Predictors of length of stay and patient satisfaction after hip and knee replacement surgery: fast-track experience in 712 patients.

Gitte Holm, Steffen Jacobsen, Henrik Husted (2008)

Very few studies have focused on patient characteristics that influence length of stay (LOS) in fast-track total hip (THR) and knee arthroplasty (TKR). The aim of this prospective study was to identify patient characteristics associated with LOS and patient satisfaction after total hip and knee replacement surgery. Between September 2003 and December 2005, 712 consecutive, unselected patients (440 women) with a mean age of 69 (31-91) years were admitted for hip and knee replacement surgery at our specialized fast-track joint replacement unit. Epidemiological, physical, and perioperative parameters were registered and correlated to LOS and patient satisfaction. 92% of the patients were discharged directly to their homes within 5 days, and 41% were discharged within 3 days. Age, sex, marital status, co-morbidity, preoperative use of walking aids, pre- and postoperative hemoglobin levels, the need for blood transfusion, ASA score, and time between surgery and mobilization, were all found to influence postoperative outcome in general, and LOS and patient satisfaction in particular. We identified several patient characteristics that influence postoperative outcome, LOS, and patient satisfaction in our series of consecutive fast-track joint replacement patients, enabling further attention to be paid to certain aspects of surgery and rehabilitation.
