ABSTRACT
Pediatric advanced life support (PALS) recertification every two years is inadequate to maintain proficiency. The authors hypothesized that a standardized, recurring curriculum may enhance retention of cardiopulmonary resuscitation (CPR) skills. Monthly in situ mock code training and an annual online self-directed learning module were implemented for pediatric intensive care unit nurses, pediatric residents, and respiratory therapists at a women and children's hospital. The in situ mock codes were linked to PALS training self-efficacy (pre- and post-mock code) and feedback related surveys. CPR knowledge was assessed using an online module with pre- and post-tests. A total of 82 in situ mock code surveys and 137 online modules were completed over a 20-month period. Medical knowledge (P < .05 for 7/10 questions) and self-confidence improved (P < .001. Several staff reported a negative impact on their patient care assignments in order to participate in the mock code. However, a significant number of participants (65%) concurred with the benefits of monthly mock codes. The curriculum improved CPR efficacy by improving knowledge-based retention as well as self-confidence in their skills.

Bicaval dual lumen catheters improve the efficiency of veno-venous extracorporeal membrane oxygenation by minimizing recirculation with an innovative design, which requires precise placement of three catheter ports in the superior vena cava, right atrium, and inferior vena cava, respectively. However, the exact position of these catheter ports is usually not known during placement because they cannot be visualized with conventional radiography. We performed a retrospective review of our experience over the past year using transthoracic echocardiography to evaluate the position of the catheter ports. From a subcostal, sagittal imaging approach, we were able to identify all three catheter ports in 11 of 11 studies. At least one of the catheter ports was incorrectly positioned in 5 of 11 studies. Further prospective evaluation is necessary to determine if catheter repositioning based on transthoracic echocardiography findings can further improve the clinical efficiency of veno-venous extracorporeal membrane oxygenation.

OBJECTIVE: To characterize PubMed usage over a typical day and compare it to previous studies of user behavior on Web search engines. DESIGN: We performed a lexical and semantic analysis of 2,689,166 queries issued on PubMed over 24 consecutive hours on a typical day. MEASUREMENTS: We measured the number of queries, number of distinct users, queries per user, terms per query, common terms, Boolean operator use, common phrases, result set size, MeSH categories, used semantic measurements to group queries into sessions, and studied the addition and removal of terms from consecutive queries to gauge search strategies. RESULTS: The size of the result sets from a sample of queries showed a bimodal distribution, with peaks at approximately 3 and 100 results, suggesting that a large group of queries was tightly focused and another was broad. Like Web search engine sessions, most PubMed sessions consisted of a single query. However, PubMed queries contained more terms. CONCLUSION: PubMed's usage profile should be considered when educating users, building user interfaces, and developing future biomedical information retrieval systems.
