The 5L provided stronger validity evidence than the 3L, especially for dimensions relevant to this patient population-mobility, usual activities, and pain/discomfort.
PURPOSE. To compare morbidity and mortality after hip fracture surgery in patients withholding clopidogrel for 3 to 6 days versus ≥7 days or more. METHODS. Records of 16 men and 31 women aged 49 to 92 (mean, 80.2) years who underwent hip fracture surgery after withholding clopidogrel for 3 to 6 days (n=24) versus ≥7 days or more (n=23) were compared. The patients were taking clopidogrel owing to ischaemic heart disease (n=37), cerebrovascular disease (n=7), and intolerance to aspirin (n=3). Patient demographics, American Society of Anesthesiologists status, preoperative delay, length of hospital stay, perioperative haemoglobin reduction, receipt of blood and platelet transfusions, morbidity, and mortality were recorded. RESULTS. Respectively in the early-surgery and delayed-surgery groups, the mean surgical delay was 4.2 and 8.0 days, the mean length of hospital stay was 21.1 and 28.7 days, the mean peri-operative haemoglobin reduction was 1.5 and 1.1 g/dl, the mean units of blood transfusion per patient was 0.8 and 0.7. No severe intra-operative bleeding or wound haematoma was encountered in either group. Two patients in each group died within one month, and 2 more in the delayed-surgery group died within 3 months. The main cause of death was cardiovascular. CONCLUSION. Withholding clopidogrel for <7 days before surgery conferred no increased risk in hip fracture patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
