Incidence and trends of pediatric ovarian torsion hospitalizations in the United States, 2000-2006.

OBJECTIVE: There is significant variation in the literature regarding the characteristics that are associated with pediatric ovarian torsion and its management. National data regarding the demographics and management of pediatric ovarian torsion are lacking. Our objective was to describe the epidemiology of pediatric ovarian torsion and the rate of oophorectomy by using nationally representative data. Demographic factors and hospital characteristics that are associated with rates of oophorectomy were also explored. METHODS: This was a cohort analysis of the Healthcare Cost and Utilization Project Kids' Inpatient Database (KID) 2000, 2003, and 2006. All females aged 1 to 20 years who were hospitalized with ovarian torsion in states participating in KID 2000, KID 2003, and KID 2006 representing 900, 1224, and 1232 ovarian torsion-related hospitalizations, respectively, were included. Primary outcome measures included the incidence of ovarian torsion and rate of associated oophorectomy. Multivariable regression was used to control for patient and hospital characteristics. RESULTS: Among females aged 1 to 20 years, there were 1232 cases of ovarian torsion in KID 2006, an estimated incidence of 4.9 per 100000. A total of 713 (58%) were treated with oophorectomy. The rate of ovarian torsion-associated oophorectomy remained unchanged from 2000 to 2006. The adjusted odds of having an oophorectomy decreased by 0.95 for every increasing year of age. Residing in a lower quartile of household income by zip code increased the adjusted odds of oophorectomy. A diagnosis of benign neoplasm increased the adjusted odds of oophorectomy by 2.16. Fewer than 0.5% of ovarian torsion hospitalizations were associated with malignant neoplasm. CONCLUSIONS: Nationally representative hospital data indicate that ovarian torsion is uncommon but occurs in all ages and is typically associated with normal ovaries or benign lesions. Improved awareness of the epidemiology may help to guide management. Ongoing analysis to identify factors that are associated with successful conservative management is warranted.

Parental preferences for boarding locations when a children's hospital exceeds capacity.

STUDY OBJECTIVE: Our objective is to determine parental preferences for boarding locations when a children's hospital is at full capacity. We also assess parental interest in transfer to a general hospital when a children's hospital is experiencing crowding. METHODS: Eligible patients were surveyed within 24 hours of admission. Surveys were completed in emergency department (ED) and inpatient areas. Previous admission was not required; children with chronic illnesses were included. Parents were asked whether they would prefer their child to board in an ED hallway or inpatient hallway or whether they had no preference. Parents were also asked the maximum acceptable waiting time for an inpatient bed and whether they would prefer to be transferred to another hospital should the children's hospital not have a bed available. Responses were hypothetical and confidential and did not affect care. RESULTS: A total of 382 patients met enrollment criteria and 359 (94%) were enrolled; 58.8% (95% confidence interval [CI] 53.5% to 63.9%) preferred boarding on inpatient hallways, 11.1% (95% CI 8.2% to 15.0%) preferred ED hallways, and 30.1% (95% CI 25.4% to 35.2%) had no preference. Seventy percent (95% CI 65.2% to 74.9%) of parents preferred to wait at a children's hospital despite crowding. Most parents believed that the maximum acceptable waiting time was less than or equal to 3 hours. CONCLUSION: Parents of pediatric patients prefer boarding on inpatient hallways over ED hallways. The majority of parents prefer to remain at a children's hospital despite crowded conditions, but some parents may be amenable to transfer. These results may help institutions develop strategies to improve patient satisfaction when hospital capacity is exceeded.

End-tidal carbon dioxide measurements in children with acute asthma.

OBJECTIVES: A noninvasive method to assess ventilation may aid in management of children with acute asthma. The purpose of this study was to evaluate the association between end-tidal carbon dioxide (EtCO2) values and disease severity among children with acute asthma. METHODS: This was a prospective, blinded, observational study of children 3-17 years old treated for acute asthma in a pediatric emergency department (ED). EtCO2 measurements were taken before the initiation of therapy and after each nebulization treatment (maximum of three). Peak expiratory flow rate (PEFR), Pediatric Asthma Severity Score (PASS), oxygen saturation, and disposition were recorded. Treating physicians, unaware of the EtCO2 results, made all treatment decisions, including disposition. RESULTS: One hundred children were enrolled. The mean initial EtCO2 value was 35 mm Hg (95% confidence interval = 34.3 to 36.1 mm Hg). The mean disposition EtCO2 value was 33.3 mm Hg (95% confidence interval = 32.6 to 34.4 mm Hg). PEFR measures were completed on 43 patients and PASS recorded on 100 patients. There was an overall trend toward lower EtCO2 values during treatment (p < 0.01). Sixteen patients were admitted. Initial EtCO2 values were lower among children admitted to the hospital (35.6 mm Hg vs. 32.9 mm Hg; Mann-Whitney U test; p < 0.02). EtCO2 values at disposition did not differ between groups based on PEFR, PASS, or hospital admission. CONCLUSIONS: Noninvasive bedside measurement of EtCO2 values among children with acute asthma is feasible. EtCO2 values did not distinguish children with mild disease from those with more severe disease. Further data are needed to clarify the association between EtCO2 values and other indicators of disease severity, particularly in children with more severe disease.
