Importance: Routine preoperative blood tests and electrocardiograms before low-risk surgery do not prevent adverse events or change management but waste resources and can cause patient harm. Given this, multispecialty organizations recommend against routine testing before low-risk surgery.

Objective: To determine whether a multicomponent deimplementation strategy (the intervention) would reduce low-value preoperative testing before low-risk general surgery operations.

Nasotracheal intubation is crucial for many oral and maxillofacial surgery procedures; however, it presents more challenges than orotracheal intubation and requires a higher level of training, along with various execution options. The routine use of an endotracheal tube (ETT)-first nasal fiberoptic intubation protocol is recommended, specifically in cases where orotracheal intubation is not possible or feasible. In this proposed technique, 137 randomly selected patients underwent fiberoptic nasotracheal intubation for general anesthesia utilizing a strict ETT first protocol.

Background: Federal rules mandate that hospitals publish payer-specific negotiated prices for all services. Little is known about variation in payer-negotiated prices for surgical oncology services or their relationship to clinical outcomes. We assessed variation in payer-negotiated prices associated with surgical care for common cancers at National Cancer Institute (NCI)-designated cancer centers and determined the effect of increasing payer-negotiated prices on the odds of morbidity and mortality.

Importance: Minimum volume standards have been advocated as a strategy to improve outcomes for certain surgical procedures. Hospital networks could avoid low-volume surgery by consolidating cases within network hospitals that meet volume standards, thus optimizing outcomes while retaining cases and revenue. The rates of compliance with volume standards among hospital networks and the association of volume standards with outcomes at these hospitals remain unknown.

Article Synopsis
  • Vertical integration of skilled nursing facilities (SNFs) within healthcare networks can enhance care coordination and quality, but it may also lead to increased utilization and costs since SNFs are paid per day.
  • The study assessed the impact of SNF integration on Medicare beneficiaries undergoing elective hip replacements, focusing on SNF utilization, readmissions, and spending.
  • Findings indicated that patients in integrated networks had higher SNF utilization rates and slightly lower 30-day readmission rates compared to those not in integrated systems.
