Recent Changes and Improvements in Multidisciplinary Perioperative Management From a Nutritional Perspective: Dental Specialty Should Be Considered Important

Purpose of review
Recently, multidisciplinary strategies on accelerated recovery postoperatively have been provided, and management of the perioperative period has changed and improved dramatically. We summarize the enhanced recovery after surgery (ERAS®) protocol and its outcomes from a nutritional perspective. We established the perioperative management center (PERiO), much of whose work contents conform to ERAS®, but intensive dental staff involvement is characteristic. We also summarize its outcomes.

Recent findings
ERAS® is a multimodal perioperative care pathway designed to achieve early recovery for patients undergoing a major surgery. Nutrition is a key pillar for patient-care. Throughout the perioperative period, oral nutrition is suggested as well as possible. Good outcomes have been reported by a meta-analysis of randomized controlled trials. However, dental staff are not regarded as part of the professional team. PERiO reported good outcomes of care bundles and suggested the importance of dental staff contribution. The Japanese social insurance system began to cover involvements of dental staff for perioperative oral management since 2012. Analysis of the nationwide administrative claims database in Japan concluded that preoperative oral care by a dentist significantly reduced postoperative complications in patients undergoing cancer surgery.

Summary
Currently, dental staff are not regarded as key professionals of ERAS®, although dental staff can contribute to good outcomes in the perioperative period and PERiO, and consequently the Japanese universal health insurance coverage system covering involvements of dental staff for perioperative oral management showed good outcomes. Therefore, further clinical studies involving the dental specialty should be considered important for perioperative management from nutritional perspectives.
