| Abstract |
At the national level, IgA vasculitis-related hospitalizations among children in the USA are scarce. Furthermore, nationwide epidemiology and hospital course of children with IgA vasculitis have not been fully described in the USA, and disparities by race/ethnicity remain unknown. Hospital discharge records of patients aged 19 years or younger were obtained from the 2003, 2006, 2009, and 2012 Kids' Inpatient Database, and they were weighted to estimate the annual hospitalization rates with respect to age, gender, and race/ethnicity in the USA. Annual hospitalization rates were calculated using weighted case estimates and US census data. Negative binomial regression was used to ascertain the factors associated with length of hospital stay. Total annual hospitalization rates showed a significant decreasing trend, ranging from 2.45 per 100,000 children in 2003 to 1.89 per 100,000 children in 2012 (p < 0.001). The peak ages of the hospitalized children with IgA vasculitis were 2 and 7 years, and male-to-female ratios were 1.38-1.44. Factors associated with length of hospital stay were patients' ages (10-14 and 15-19 years), race/ethnicity (Hispanic, Asian, and Pacific Islander), comorbid electrolyte abnormality, GI hemorrhage, intussusception, renal symptoms, and GI symptoms. The annual hospitalization rates for IgA vasculitis are declining in the USA across multiple age groups. GI and renal manifestations are associated with increased length of hospital stay. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 September 2016.
All research outputs
#12,847,207
of 22,886,568 outputs
Outputs from Clinical Rheumatology
#1,546
of 3,012 outputs
Outputs of similar age
#168,486
of 335,711 outputs
Outputs of similar age from Clinical Rheumatology
#21
of 52 outputs
Altmetric has tracked 22,886,568 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,012 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.9. This one is in the 48th percentile – i.e., 48% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 335,711 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 52 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 59% of its contemporaries.
