Medical Operations Console Procedure Evaluation: BME Response to Crew Call Down for an Emergency

International Space Station (ISS) Mission Operations are managed by multiple flight control disciplines located at the lead Mission Control Center (MCC) at NASA-Johnson Space Center (JSC). ISS Medical Operations are supported by the complementary roles of Flight Surgeons (Surgeon) and Biomedical Engineer (BME) flight controllers. The Surgeon, a board certified physician, oversees all medical concerns of the crew and the BME provides operational and engineering support for Medical Operations Crew Health Care System. ISS Medical Operations is currently addressing the coordinated response to a crew call down for an emergent medical event, in particular when the BME is the only Medical Operations representative in MCC. In this case, the console procedure BME Response to Crew Call Down for an Emergency will be used. The procedure instructs the BME to contact a Surgeon as soon as possible, coordinate with other flight disciplines to establish a Private Medical Conference (PMC) for the crew and Surgeon, gather information from the crew if time permits, and provide Surgeon with pertinent console resources. It is paramount that this procedure is clearly written and easily navigated to assist the BME to respond consistently and efficiently. A total of five BME flight controllers participated in the study. Each BME participant sat in a simulated MCC environment at a console configured with resources specific to the BME MCC console and was presented with two scripted emergency call downs from an ISS crew member. Each participant used the procedure while interacting with analog MCC disciplines to respond to the crew call down. Audio and video recordings of the simulations were analyzed and each BME participant's actions were compared to the procedure. Structured debriefs were conducted at the conclusion of both simulations. The procedure was evaluated for its ability to elicit consistent responses from each BME participant. Trials were examined for deviations in procedure task completion and/or navigation, in particular the execution of the Surgeon call sequence. Debrief comments were used to analyze unclear procedural steps and to discern any discrepancies between the procedure and generally accepted BME actions. The sequence followed by BME participants differed considerably from the sequence intended by the procedure. Common deviations included the call sequence used to contact Surgeon, the content of BME and crew interaction and the gathering of pertinent console resources. Differing perceptions of task priority and imprecise language seem to have caused multiple deviations from the procedure s intended sequence. The study generated 40 recommendations for the procedure, of which 34 are being implemented. These recommendations address improving the clarity of the instructions, identifying training considerations, expediting Surgeon contact, improving cues for anticipated flight control team communication and identifying missing console tools

Psychosocial correlates, outcome, and stability of abnormal adolescent eating behavior in community samples of young people

OBJECTIVE: The current study investigated psychosocial correlates of abnormal adolescent eating behavior at three times during adolescence and young adulthood and its association with psychiatric diagnosis in young adulthood in a community sample. METHOD: Sixty-four (10.5%) high-risk subjects (mean age 15 years) with abnormal eating behavior were identified at Time 1, another 252 (16.9%) were identified at Time 2 (mean age 16.2 years), and 164 (16.9%) were identified at Time 3 (mean age 19.7 years) and compared with three control groups matched for age and gender. Dependent measures included emotional and behavioral problems, life events, coping capacities, self-related cognition, social network, and family functions. Outcome was measured additionally by structured psychiatric interviews, and stability of abnormal eating behavior was studied in a longitudinal sample of 330 subjects. RESULTS: Few subjects showed more than one of five criteria of abnormal eating behavior. High-risk subjects shared a very similar pattern at all three times. They were characterized by higher scores for emotional and behavioral problems, more life events including more negative impact, less active coping, lower self-esteem, and less family cohesion. Among 10 major psychiatric disorders, only clinical eating disorders at Time 3 shared a significant association with abnormal eating disorder at the same time whereas high-risk status at Times 1 and 2 did not predict any psychiatric disorder at Time 3. Stability of abnormal eating behavior across time was very low. Stability of abnormal eating behavior across time was very low. DISCUSSION: Abnormal eating behavior in adolescence and young adulthood is clearly associated with various indicators of psychosocial maladaption. In adolescence, it does not significantly predict any psychiatric disorder including eating disorder in young adulthood and it is predominantly a transient feature
