    Impact of early postoperative oral nutritional supplement utilization on clinical outcomes in colorectal surgery.
    (Perioperative medicine (London, England), 2020-01) Williams, David GA; Ohnuma, Tetsu; Krishnamoorthy, Vijay; Raghunathan, Karthik; Sulo, Suela; Cassady, Bridget A; Hegazi, Refaat; Wischmeyer, Paul E
    Background:Small randomized trials of early postoperative oral nutritional supplementation (ONS) suggest various health benefits following colorectal surgery (CRS). However, real-world evidence of the impact of early ONS on clinical outcomes in CRS is lacking. Methods:Using a nationwide administrative-financial database (Premier Healthcare Database), we examined the association between early ONS use and postoperative clinical outcomes in patients undergoing elective open or laparoscopic CRS between 2008 and 2014. Early ONS was defined as the presence of charges for ONS before postoperative day (POD) 3. The primary outcome was composite infectious complications. Key secondary efficacy (intensive care unit (ICU) admission and gastrointestinal complications) and falsification (blood transfusion and myocardial infarction) outcomes were also examined. Propensity score matching was used to assemble patient groups that were comparable at baseline, and differences in outcomes were examined. Results:Overall, patients receiving early ONS were older with greater comorbidities and more likely to be Medicare beneficiaries with malnutrition. In a well-matched sample of early ONS recipients (n = 267) versus non-recipients (n = 534), infectious complications were significantly lower in early ONS recipients (6.7% vs. 11.8%, P < 0.03). Early ONS use was also associated with significantly reduced rates of pneumonia (P < 0.04), ICU admissions (P < 0.04), and gastrointestinal complications (P < 0.05). There were no significant differences in falsification outcomes. Conclusions:Although early postoperative ONS after CRS was more likely to be utilized in elderly patients with greater comorbidities, the use of early ONS was associated with reduced infectious complications, pneumonia, ICU admission, and gastrointestinal complications. This propensity score-matched study using real-world data suggests that clinical outcomes are improved with early ONS use, a simple and inexpensive intervention in CRS patients.

    The rising tide of opioid use and abuse: the role of the anesthesiologist.
    (Perioperative medicine (London, England), 2018-01) Koepke, Elena J; Manning, Erin L; Miller, Timothy E; Ganesh, Arun; Williams, David GA; Manning, Michael W
    Opioid use has risen dramatically in the past three decades. In the USA, opioid overdose has become a leading cause of unintentional death, surpassing motor vehicle accidents. A patient's first exposure to opioids may be during the perioperative period, a time where anesthesiologists have a significant role in pain management. Almost all patients in the USA receive opioids during a surgical encounter. Opioids have many undesirable side effects, including potential for misuse, or opioid use disorder. Anesthesiologists and surgeons employ several methods to decrease unnecessary opioid use, opioid-related adverse events, and side effects in the perioperative period. Multimodal analgesia, enhanced recovery pathways, and regional anesthesia are key tools as we work towards optimal opioid stewardship and the ideal of effective analgesia without undesirable sequelae.
