Feasibility, implementation, and outcomes of in situ simulation-based curriculum to manage common emergencies in the pediatric post-anesthesia care unit.

PURPOSE: Studies have shown that most critical events that occur in the post-anesthesia care unit (PACU), including cardiac arrests, are preventable and respiratory in origin. Admission to the PACU necessitates transfer of care from anesthesiology staff to PACU nurses. The aim of the study is to assess a) feasibility in implementing an in-situ curriculum for PACU nurses to manage common pediatric emergencies, b) the effectiveness of the curriculum in improving self-confidence of the PACU nurses in performing essential skills c) nurses'' perception of such an offering. DESIGN AND METHODS: This was a single center curricular evaluation study. Anonymous surveys were used to assess curriculum effectiveness by comparing self-reported confidence in the execution of key technical skills and application of knowledge in a real clinical environment at three time points: baseline, immediately post-simulation, and 3 months later. RESULTS: Of 50 PACU nurses, 80%, 98% and 58% responded to the targeted needs assessment, post-simulation and follow up (at 3 months) survey respectively. Self-reported confidence levels for most of the essential skills were significantly increased immediately after simulation and at 3 months. Most of the participants responded that the simulation training helped them improve care of hypoxic (83%) and hypotensive (62%) patients in the PACU. CONCLUSION: Implementation of in situ curriculum for PACU nurses was feasible. The self-reported confidence in performing essential skills increased significantly and the nurses could apply these skills in real clinical environment. PRACTICE IMPLICATIONS: Interprofessional simulation should be implemented in all high risk units to optimize safety of children.

Agreement of urine specific gravity measurements between manual and digital refractometers.

CONTEXT: Urine specific gravity (Usg), measured by a handheld manual refractometer (MAN), has been recognized as a valid and practical means of assessing hydration status. Newer, digital refractometers are faster and more user friendly but have not been validated against the traditional MAN. OBJECTIVE: To compare the reliability and validity of 2 digital refractometer models and a MAN. DESIGN: Descriptive laboratory study. SETTING: Research laboratory. PATIENTS OR OTHER PARTICIPANTS: Sample of convenience was recruited from the local university and surrounding community (n = 82). INTERVENTION(S): Participants provided multiple urine samples (n = 124) over a 5-month period under various hydration conditions. MAIN OUTCOME MEASURE(S): Urine specific gravity was compared among a MAN, a digital refractometer requiring the prism to be dipped (DIP) into a urine sample, and a digital refractometer that requires urine to be pipetted (PIP) onto its prism for analysis. RESULTS: The MAN measurements were strongly correlated with the DIP (r = 0.99, P < .001) and PIP (r = 0.97, P < .001) measurements. Bland-Altman analyses revealed slight mean underestimation (95% upper and lower levels of agreement) between MAN and DIP (-0.0012 [0.0028] and PIP -0.0011 [0.0035], respectively) and trends toward increased underestimation at higher Usg. Measurement error ≥ .005 was greater for PIP (4/124, 3.2%) than for DIP (2/124, 1.6%). CONCLUSIONS: Negligible differences were exhibited between PIP and DIP, with both displaying acceptable reliability and validity compared with the MAN. However, the Bland-Altman analysis suggests underestimation bias for the DIP and PIP as Usg increases, with the potential for rare but substantial underestimation when using PIP that should be recognized by clinicians, particularly when used as a screening measure in weight-class sports.

Protective role of resting heart rate on all-cause and cardiovascular disease mortality.

OBJECTIVE: To study the protective role of lower resting heart rate (RHR) in cardiovascular disease (CVD) and all-cause mortality. PATIENTS AND METHODS: Patients (n=53,322) who received a baseline medical examination between January 1, 1974, and December 31, 2002, were recruited from the Cooper Clinic, Dallas, Texas. They completed a medical questionnaire and underwent clinical evaluation. Patients with CVD or cancer or who had less than 1 year of mortality follow-up were excluded from the study. Relative risks and 95% CIs for all-cause and CVD mortality across RHR categories were estimated using Cox proportional hazards models. RESULTS: Highest cardiorespiratory fitness with lower mortality was found in individuals with an RHR of less than 60 beats/min. Similarly, patients with a higher RHR (≥80 beats/min) were at greater risk for CVD and all-cause mortality compared with an RHR of less than 60 beats/min. This analysis was followed by stratification of the data by hypertension, where hypertensive individuals with high RHRs (≥80 beats/min) were found to be at greater risk for CVD and all-cause mortality compared with those with hypertension and lower RHRs (<60 beats/min). In addition, unfit individuals with high RHRs had the greatest risk of CVD and all-cause mortality. The unfit with low RHR group had a similar risk for CVD and all-cause mortality as the fit with high RHR group. CONCLUSION: Lower cardiorespiratory fitness levels and higher RHRs are linked to greater CVD and all-cause mortality.

Sports nutrition knowledge among collegiate athletes, coaches, athletic trainers, and strength and conditioning specialists.

CONTEXT: Coaches, athletic trainers (ATs), strength and conditioning specialists (SCSs), and registered dietitians are common nutrition resources for athletes, but coaches, ATs, and SCSs might offer only limited nutrition information. Little research exists about sports nutrition knowledge and current available resources for nutrition information for athletes, coaches, ATs, and SCSs. OBJECTIVE: To identify resources of nutrition information that athletes, coaches, ATs, and SCSs use; to examine nutrition knowledge among athletes, coaches, ATs, and SCSs; and to determine confidence levels in the correctness of nutrition knowledge questions within all groups. DESIGN: Cross-sectional study. SETTING: National Collegiate Athletic Association Division I, II, and III institutions across the United States. PATIENTS AND OTHER PARTICIPANTS: The 579 participants consisted of athletes (n = 185), coaches (n = 131), ATs (n = 192), and SCSs (n = 71). MAIN OUTCOME MEASURE(S): Participants answered questions about nutrition resources and domains regarding basic nutrition, supplements and performance, weight management, and hydration. Adequate sports nutrition knowledge was defined as an overall score of 75% in all domains (highest achievable score was 100%). RESULTS: Participants averaged 68.5% in all domains. The ATs (77.8%) and SCSs (81.6%) had the highest average scores. Adequate knowledge was found in 35.9% of coaches, 71.4% of ATs, 83.1% of SCSs, and only 9% of athletes. The most used nutrition resources for coaches, ATs, and SCSs were registered dietitians. CONCLUSIONS: Overall, we demonstrated that ATs and SCSs have adequate sports nutrition knowledge, whereas most coaches and athletes have inadequate knowledge. Athletes have frequent contact with ATs and SCSs; therefore, proper nutrition education among these staff members is critical. We suggest that proper nutrition programming should be provided for athletes, coaches, ATs, and SCSs. However, a separate nutrition program should be integrated for ATs and SCSs. This integrative approach is beneficial for the continuity of care, as both categories of professionals might be developing and integrating preventive or rehabilitative programs for athletes.

Prevalence of eating disorder risk and body image distortion among National Collegiate Athletic Association Division I varsity equestrian athletes.

CONTEXT: Participation in appearance-based sports, particularly at the collegiate level, may place additional pressures on female athletes to be thin, which may increase the likelihood of their resorting to drastic weight control measures, such as disordered eating behaviors. OBJECTIVES: (1) To estimate the prevalence and sources of eating disorder risk classification by academic status (freshman, sophomore, junior, or senior) and riding discipline (English and Western), (2) to examine riding style and academic status variations in body mass index (BMI) and silhouette type, and (3) to examine these variations across eating disorder risk classification type (eg, body image disturbances). DESIGN: Cross-sectional study. SETTING: Seven universities throughout the United States. PATIENTS OR OTHER PARTICIPANTS: A total of 138 participants volunteered (mean age = 19.88 ± 1.29 years). They represented 2 equestrian disciplines English riding (n = 91) and Western riding (n = 47). MAIN OUTCOME MEASURE(S): Participants self-reported menstrual cycle history, height, and weight. We screened for eating disorder risk behaviors with the Eating Attitudes Test and for body disturbance with sex-specific BMI silhouettes. RESULTS: Based on the Eating Attitudes Test, estimated eating disorder prevalence was 42.0% in the total sample, 38.5% among English riders, and 48.9% among Western riders. No BMI or silhouette differences were found across academic status or discipline in disordered eating risk. Overall, participants perceived their body images as significantly larger than their actual physical sizes (self-reported BMI) and wanted to be significantly smaller in both normal clothing and competitive uniforms. CONCLUSIONS: Disordered eating risk prevalence among equestrian athletes was similar to that reported in other aesthetic sports and lower than that in nonaesthetic sports. Athletic trainers working with these athletes should be sensitive to these risks and refer athletes as needed to clinicians knowledgeable about disordered eating. Professionals working with this population should avoid making negative comments about physical size and appearance.
