The Power of Connections: AAP COVID-19 ECHO Accelerates Responses During a Public Health Emergency.

CONTEXT: Pediatric providers across the United States have sought guidance on how to care for the nation's children during the uncertain historic times of the COVID-19 pandemic. The health care community has been challenged by the unprecedented burden of caring for patients when they have evolving guidelines and limited information about the effects of the virus on children. PROGRAM: In response, the American Academy of Pediatrics (AAP) rapidly launched a national initiative to increase child health professionals' knowledge, skills, and self-efficacy. This COVID-19 ECHO (Extension for Community Healthcare Outcomes) program created communities of learners among child health professionals and subject matter expert faculty using didactic and case-based presentations that foster an "all-teach, all-learn" approach. IMPLEMENTATION: The initial AAP COVID-19 ECHO program hosted more than 900 participants in 127 individual virtual sessions, with approximately 25 participants per session. The evolving nature of the pandemic necessitated dynamic and continuous bidirectional flow of concerns and information relevant to participants. Session topics were selected in a "just-in-time" fashion based on participant feedback from the prospective postsession surveys and faculty recommendations; speakers brought data and expert recommendations. EVALUATION: To assess impact, the AAP used a mixed-methods approach to evaluate the program's effectiveness in meeting its educational objectives. The 2-phase evaluation collected quantitative and qualitative data through an integrated feedback structure that utilized prospective postsession and retrospective postprogram surveys, along with postprogram focus groups. DISCUSSION: As the COVID-19 pandemic surges and another influenza season is upon us, the ECHO model is an effective strategy for facilitating bidirectional communication and education to build child health professionals' knowledge, skills, and self-efficacy during an unprecedented and ongoing public health emergency. KEY POINTS: The ECHO model is an effective strategy for health care organizations to facilitate bidirectional communication and education in building health professionals' clinical knowledge, skills, and self-efficacy during the unprecedented and ongoing public health emergency of the COVID-19 pandemic.

Combination therapy with infliximab and azathioprine is superior to monotherapy with either agent in ulcerative colitis.

BACKGROUND & AIMS: The comparative efficacy and safety of infliximab and azathioprine therapy alone or in combination for ulcerative colitis (UC) have not been evaluated previously. METHODS: This randomized, double-blind trial evaluated the efficacy and safety of 16 weeks of treatment with infliximab monotherapy, azathioprine monotherapy, or the 2 drugs combined in tumor necrosis factor-a antagonist-naive adults with moderate to severe UC. Patients were assigned randomly to receive intravenous infusions of infliximab 5 mg/kg at weeks 0, 2, 6, and 14 plus daily oral placebo capsules; oral azathioprine 2.5 mg/kg daily plus placebo infusions on the infliximab schedule; or combination therapy with the 2 drugs. Corticosteroid-free clinical remission (primary end point, week 16) was evaluated at weeks 8 and 16. The study was terminated before the enrollment target was reached. RESULTS: A total of 239 patients were included in efficacy analyses. Baseline characteristics were similar between treatment groups. Corticosteroid-free remission at week 16 was achieved by 39.7% (31 of 78) of patients receiving infliximab/azathioprine,compared with 22.1% (17 of 77) receiving infliximab alone(P =.017) and 23.7% (18 of 76) receiving azathioprine alone(P =.032). Mucosal healing at week 16 occurred in 62.8% (49 of 78) of patients receiving infliximab/azathioprine, compared with 54.6% (42 of 77) receiving infliximab (P = .295) and 36.8% (28 of 76) receiving azathioprine (P =.001). Serious infections occurred in 2 patients (1 patient receiving infliximab,and 1 patient receiving azathioprine). CONCLUSIONS: Anti­tumor necrosis factor-a­naive patients with moderate to severe UC treated with infliximab plus azathioprine were more likely to achieve corticosteroid-free remission at 16 weeks than those receiving either monotherapy. Combination therapy led to significantly better mucosal healing than azathioprine monotherapy. ClinicalTrials.gov number, NCT00537316.
