The New PGY-1 Year: Lessons Learned.

PURPOSE OF REVIEW: Describe the ACGME's changes to the PGY-1 year in urology and discuss the benefits and challenges faced by training programs. RECENT FINDINGS: There are no publications detailing the integration of the PGY-1 year in urology; however, response of other surgical subspecialties to their own integration has been studied. Benefits of integration include earlier exposure to techniques and knowledge specific to urology, potentially leading to increased preparedness for next steps in training and exams. Program directors have more flexibility to select rotations relevant to urology. Resident wellness may be improved as interns are incorporated into the department earlier and can help distribute the workload for senior residents. Challenges include decreased exposure to basic surgical knowledge and skills, decreased camaraderie with general surgery colleagues, and difficulties associated with evaluating interns who are spending limited time with urology departments. Overall, the change seems to have a positive impact on urological training.

Validation of the Innocor device for noninvasive measurement of oxygen consumption in children and adults.

Outpatient measurements of oxygen consumption (VO2) and cardiac output (CO) are valuable in the management of pediatric cardiac disease. Current methods are inaccurate and cumbersome or require invasive procedures. New devices to measure these variables in adults have not been rigorously tested for children. The Innocor system uses a photoacoustic analyzer to measure gas content for noninvasive measurement of VO2 and CO. This study sought to validate Innocor-derived VO2 measurements in children and adults by comparing them against the gold standard Douglas bag method. Subjects were tested in an outpatient setting. Adaptations were made for pediatric patients based on weight. Resting VO2 measurements were obtained simultaneously by the Innocor system and Douglas bag during 3 min. The study enrolled 31 children (mean age, 12.2 years; range, 7-17 years, 17 girls) and 29 adults (mean age, 36.7 years; range, 19-57 years; 17 women). Strong correlation between the two techniques was seen for both the adults (R (2) = 0.88) and the children (R (2) = 0.82). The average discrepancy between the Innocor and Douglas bag measurements was 1.7 % (range, 0.6-19.1 %) for the adults, and 5.4 % (range, 0.1-32.2 %) for the children. The discrepancy was more than 15 % for 17 % of the adults and 22 % of the children, with the Innocor device tending to overestimate VO2 in children compared with the Douglas bag. This trend was not seen in adults. The Innocor system has excellent correlation with the Douglas bag and shows promise for noninvasive measurement of VO2 and CO in the school-age pediatric population.
