A systematic review and meta-analysis of anesthesia type on hip fracture post-surgery outcomes.

ABSTRACT

Objective: To compare technical, clinical, and safety outcomes among hip fracture patients treated with procedures supplemented by general anesthesia (GA) or spinal/regional anesthesia (S/R). Data sources We searched for original studies on PubMed, Ovid MEDLINE, Ovid Embase, and Cochrane databases. Study selection Studies that reported clinical outcomes in patients that underwent hip fracture surgery, had available data on type of anesthesia administered, and clinical follow-up data were selected for data extraction. Data extraction The primary outcomes of interest were odds of mortality, including in-hospital, 30-day, 90-day, and 1-year mortality. Various adverse events (AEs) were also compared. Data synthesis: Twenty-eight studies met our selection criteria, including 190,394 patients. A total of 107,314 (56.4%) patients were treated with procedures involving GA while 83,080 (43.6%) were treated with procedures involving S/R. There was no difference in 30-day or >1-year mortality rates between the GA and SR groups; however, compared to S/R group, the GA group had a significantly higher odds of in-hospital (P = .004) and 90-day mortality (P = .004). There was no difference in odds of adverse events between the GA and the S/R group. Conclusions: Patients administered S/R for hip fracture procedures demonstrate lower risk of in-hospital mortality and 90-day mortality compared to patients administered GA. Level of evidence Therapeutic level III.
