Observational StudyElectronic Audit and Feedback With Positive Rewards Improve Anesthesia Provider Compliance With a Barcode-Based Drug Safety System.
We implemented a previously described barcode-based drug safety system in all of our anesthetizing locations. Providers were instructed to scan the barcode on syringes using our Anesthesia Information Management System before drug administration, but the rate of provider adherence was low. We studied an implementation intervention intended to increase the rate of scanning. ⋯ Feedback of individual provider performance data from the anesthesia information system to providers can be used in conjunction with other measures to improve performance. Despite improved average performance, there was marked variation in performance between individuals, and some individuals had marked oscillation of their performance over time.

Contemporary Academic Contributions From Anesthesiologists in Adult Critical Care Medicine.
Anesthesiology has a long relationship with critical care medicine (CCM). However, US anesthesiologists are less likely to practice CCM than non-US anesthesiologists. To date, no studies have compared academic contributions in CCM between US anesthesiologists and non-US anesthesiologists. The objective of our study was to use recent trends in critical care publications as a surrogate for academic contribution among US and non-US anesthesiologists. ⋯ When compared to non-US anesthesiologists, US anesthesiologists had more CCM publications in anesthesiology journals and fewer publications in multidisciplinary CCM journals. The number of anesthesiology CCM publications decreased for both US and non-US anesthesiologists throughout the study period.

Segmented Regression and Difference-in-Difference Methods: Assessing the Impact of Systemic Changes in Health Care.
Perioperative investigators and professionals increasingly seek to evaluate whether implementing systematic practice changes improves outcomes compared to a previous routine. Cluster randomized trials are the optimal design to assess a systematic practice change but are often impractical; investigators, therefore, often select a before-after design. In this Statistical Grand Rounds, we first discuss biases inherent in a before-after design, including confounding due to periods being completely separated by time, regression to the mean, the Hawthorne effect, and others. ⋯ Difference-in-difference methods add a concurrent control, enabling yet stronger inference. When done well, the discussed methods permit robust inference on the effect of an intervention, albeit still requiring assumptions and having limitations. Methods are demonstrated using an interrupted time series study in which anesthesiologists took responsibility for an adult medical emergency team from internal medicine physicians in an attempt to improve outcomes.

Comparative Study Observational StudyHeterogeneity Among Hospitals in the Percentages of All Lumbosacral Epidural Steroid Injections Where the Patient Had Received 4 or More in the Previous Year.
Current guidelines for the administration of therapeutic epidural injections suggest that these be limited to a maximum of 4 per year. We sought to gain an understanding of the proportion of lumbosacral epidural injections administered to patients who had received ≥4 such injections during the preceding 364 days, and whether these proportions varied among hospitals. ⋯ Although most patients received only 1 lumbosacral steroid injection within 1 year, 1.27% of patients received 5 or more, and 1.91% of injections were the fifth or greater. Several hospitals had significantly greater than the overall average percent of steroid injections which were fifth or more. This heterogeneity warrants study of whether annual steroid injections per patient should be a clinical quality measure for the care received by patients with lower back pain or whether payment should be greater when injections are in accordance with guidelines.

Observational StudyThe Migration of Caudally Threaded Thoracic Epidural Catheters in Neonates and Infants.
The migration of pediatric thoracic epidural catheters via a thoracic insertion site has been described. We assessed the migration of caudally threaded thoracic epidural catheters in neonates and infants at our institution. ⋯ Epidural catheter migration occurs commonly in neonates and infants. Postoperative imaging is crucial to confirm catheter tip location after epidural catheter placement, as failure to assess catheter migration might result in suboptimal analgesia or other undesirable outcomes.
