Anesthesia-Related Closed Claims in Free-Standing Ambulatory Surgery Centers.
As higher acuity procedures continue to move from hospital-based operating rooms (HORs) to free-standing ambulatory surgery centers (ASCs), concerns for patient safety remain high. We conducted a contemporary, descriptive analysis of anesthesia-related liability closed claims to understand risks to patient safety in the free-standing ASC setting, compared to HORs. ⋯ This analysis of medical malpractice claims may indicate higher-than-expected patient and procedural complexity in free-standing ASCs, presenting patient safety concerns and opportunities for improvement. Ambulatory anesthesia practices should consider improving safety culture and communication with families while ensuring that providers have up-to-date training and resources to safely perform routine anesthesia procedures.

Our primary objective was to compare the marginal intraoperative cost of 3 different methods for pedicle screw placement as part of transforaminal lumbar interbody fusions (TLIFs). Specifically, we used time-driven activity-based costing to compare costs between robot-assisted TLIF (RA-TLIF), TLIF with intraoperative navigation (ION-TLIF), and freehand (non-navigated, nonrobotic) TLIF. ⋯ We demonstrate a novel use of time-driven activity-based costing methodology to compare different modalities for executing the same type of lumbar fusion procedure. RA-TLIF entails significantly higher supply cost when compared with other modalities, which explains its association with higher total intraoperative cost. The use of ION, however, does not add extra expense compared with freehand TLIF when accounting for confounders. This might have implications as surgeons and hospitals move toward bundled payments.

We sought to determine if genetically modified porcine kidneys used for xenotransplantation had sufficient tissue integrity to support long-term function in a human recipient. ⋯ The findings of this study suggest kidneys from 10-gene edited porcine donors have sufficient tissue integrity to tolerate xenotransplantation into a living human recipient. There was no evidence of anastomotic complications, and the xenografts tolerated needle biopsy without issue. Xenograft growth occurred but plateaued by the study end; further observation and investigation will be required to confirm this finding and elucidate underlying mechanisms.
