Evaluated the effect of a geriatric-anesthesiologic intervention program (IP) for the prevention and treatment of acute confusional states (ACS) in 103 elderly patients (aged 65–102 yrs) treated for femoral neck fractures. The outcome of the intervention was compared with that of an earlier study by Y. Gustafson et al (1988) comprising 111 patients. The IP included pre- and post-operative geriatric assessments, oxygen therapy and early surgery. The incidence of ACS was lower, less severe, and of shorter duration in the IP. The IP reduced the incidence, severity, and duration of ACS which resulted in a shortened orthopedic ward stay. (PsycINFO Database Record (c) 2013 APA, all rights reserved)
