Assessment of Disaster Preparedness at the Household Level in a Pediatric Cardiology Clinic Population.

Natural and human-provoked disasters pose serious health risks to children, particularly children and youth with special healthcare needs, including many cardiology patients. The American Academy of Pediatrics (AAP) provides preparedness recommendations for families, but little is known about recommendation adherence. Caregivers of children seen in a pediatric cardiology clinic network were recruited to complete an electronic survey. Participants self-reported child medical history and their household's implementation of AAP recommended disaster preparedness items. Families received a link to AAP resources and a child ID card. Data were analyzed using descriptive statistics with Fisher's exact and Wilcoxon rank sum tests. 320 caregivers participated in the study, of whom 124 (38.8%) indicated that their child has a diagnosed cardiac condition, and 150 (46.9%) indicated that their child had special healthcare needs. The average preparedness item completion rate was 70.7% for household preparedness, 40.1% for reunification preparedness, and 26.3% for community preparedness. Households of children with medical needs had similar rates of preparedness compared to overall rates. Of all respondents, 27.8% previously received disaster preparedness resources, 67.7% would like resources on discussing disaster preparedness, and 93.0% intend to talk with their household about disaster preparedness after completing the survey. These results demonstrate a gap between AAP recommendations and household-level disaster preparedness, including patients with cardiac conditions and those with special healthcare needs. Families expressed that they were interested in getting resources for disaster preparedness. Pediatric cardiologists may consider asking about disaster preparedness and providing disaster preparedness resources tailored to the needs of their patients.

Utility of apical four-chamber longitudinal strain in the assessment of childhood cancer survivors: A multicenter study.

BACKGROUND: A previous multicenter study showed that longitudinal changes in standard cardiac functional parameters were associated with the development of cardiomyopathy in childhood cancer survivors (CCS). Evaluation of the relationship between global longitudinal strain (GLS) changes and cardiomyopathy risk was limited, largely due to lack of quality apical 2- and 3-chamber views in addition to 4-chamber view. We sought to determine whether apical 4-chamber longitudinal strain (A4LS) alone can serve as a suitable surrogate for GLS in this population. METHODS: A4LS and GLS were measured in echocardiograms with acceptable apical 2-, 3-, and 4-chamber views. Correlation was evaluated using Pearson and Spearman coefficients, and agreement was evaluated with Bland-Altman plots. The ability of A4LS to identify normal and abnormal values compared to GLS as the reference was evaluated. RESULTS: Among a total of 632 reviewed echocardiograms, we identified 130 echocardiograms from 56 patients with adequate views (38% female; mean age at cancer diagnosis 8.3 years; mean follow-up 9.4 years). Correlation coefficients between A4LS and GLS were .89 (Pearson) and .85 (Spearman), with Bland-Altman plot of GLS-A4LS showing a mean difference of -.71 ± 1.8. Compared with GLS as the gold standard, A4LS had a sensitivity of 86% (95% CI 79%-93%) and specificity of 82% (69%-95%) when using normal range cutoffs and 90% (82%-97%) and 70% (58%-81%) when using ±2 standard deviations. CONCLUSION: A4LS performs well when compared with GLS in this population. Given the more recent adoption of apical 2- and 3-chamber views in most pediatric echocardiography laboratories, A4LS is a reasonable stand-alone measurement in retrospective analyses of older study cohorts and echocardiogram biorepositories.
