Effect of implementation of a surgical safety checklist on perioperative and postoperative complications at an academic institution in North America.

OBJECTIVE: To evaluate the efficacy of a surgical safety checklist (SSC) in reducing perioperative and postoperative complications. STUDY DESIGN: Before-and-after intervention study. ANIMALS: Client-owned dogs (n = 633) and cats (n = 44). METHODS: Consecutive surgeries were enrolled in the study. The "before" phase consisted of 267 surgeries performed without an SSC (SSC- ) followed by 75 SSC- surgeries in which a trained observer was in the operating room to detect possible complications. An SSC was then implemented in the operating rooms during 1 week. The "after" phase consisted of 58 surgeries in which a safety checklist (SSC+ ) and an observer were used and 277 SSC+ surgeries without an observer. Complications were prospectively recorded when witnessed by the observer, and all other perioperative complications were retrospectively recorded from veterinary records and client telephone communication. RESULTS: There were more perioperative and postoperative complications when surgeries were performed without an SSC (140/342 [40.9%; 95% CI, 35.7%-46.4%]) than there were when surgeries were performed with an SSC (98/335 [29.3%; 95% CI, 24.4%-34.4%]; P = .002). Surgical checklist use, presence of an observer, American Society of Anesthesiologists score, and anesthesia time were all independently associated with the odds of complications. CONCLUSION: Implementation of an SSC in an academic teaching hospital decreased the odds of perioperative and postoperative surgical complications. CLINICAL SIGNIFICANCE: This study supports the use of an SSC to prevent surgical complications in veterinary teaching hospitals.

Hemochromatosis in Two Female Olive Baboons (Papio anubis).

This report describes hemochromatosis associated with chronic parenteral iron dextran administration in 2 female olive baboons (Papio anubis). These baboons were enrolled on an experimental protocol that induced and maintained anemia by periodic phlebotomy for use in studying potential treatments for sickle cell anemia. The 2 baboons both presented with clinical signs consistent with iron overload, including decreased appetite, weight loss, elevated liver enzymes, and hepatosplenomegaly. Histopathologic findings supported a morphologic diagnosis of systemic hemosiderosis, as evidenced by the overwhelming presence of iron in the reticuloendothelial system and liver after the application of Prussian blue stain. This finding, combined with the clinical presentation, lead to a final diagnosis of hemochromatosis. This case report suggests that providing anemic patients with chronic parenteral iron supplementation in the absence of iron deficiency can result in iatrogenic iron overload and subsequent systemic toxicity. Furthermore, these subjects may present with hemochromatosis and its associated clinical signs many years after cessation of iron supplementation.
