Improving Quality of Acute Asthma Care in US Hospitals Changes Between 1999-2000 and 2012-2013
BackgroundLittle is known about the longitudinal change in the quality of acute asthma care for hospitalized children and adults in the United States. We investigated whether the concordance of inpatient asthma care with the national guidelines improved over time, identified hospital characteristics predictive of guideline concordance, and determined whether guideline-concordant care is associated with a shorter hospital length of stay (LOS).MethodsThis study was an analysis of data from two multicenter chart review studies of hospitalized patients aged 2 to 54 years with acute asthma during two time periods: 1999-2000 and 2012-2013. Outcomes were guideline concordance at the patient and hospital levels, and association of patient composite concordance with hospital LOS.ResultsThe analytic cohort for the comparison of guideline concordance comprised 1,634 patients: 834 patients from 1999-2000 vs 800 patients from 2012-2013. Over these 15 years, inpatient asthma care became more concordant at the hospital-level, with the mean composite score increasing from 74 to 82 (P < .001). However, during 2012-2013, wide variability in guideline concordance of acute asthma care remained across hospitals, with the greatest variation in provision of individualized written action plan at discharge (SD, 36). Guideline concordance was significantly lower in Midwestern and Southern hospitals compared with Northeastern hospitals. After adjusting for severity, patients who received care perfectly concordant with the guidelines had significantly shorter hospital LOS (-14% [95% CI, -23 to -4]; P = .009).ConclusionsBetween 1999 and 2013, the guideline concordance of acute asthma care for hospitalized patients improved. However, interhospital variability remains substantial. Greater concordance with evidence-based guidelines was associated with a shorter hospital LOS
The proportion of different BCR-ABL1 transcript types in chronic myeloid leukemia. An international overview
There are different BCR-ABL1 fusion genes that are translated into proteins that are different from each other, yet all leukemogenic, causing chronic myeloid leukemia (CML) or acute lymphoblastic leukemia. Their frequency has never been systematically investigated. In a series of 45503 newly diagnosed CML patients reported from 45 countries, it was found that the proportion of e13a2 (also known as b2a2) and of e14a2 (also known as b3a2), including the cases co-expressing e14a2 and e13a2, was 37.9% and 62.1%, respectively. The proportion of these two transcripts was correlated with gender, e13a2 being more frequent in males (39.2%) than in females (36.2%), was correlated with age, decreasing from 39.6% in children and adolescents down to 31.6% in patients ≥ 80 years old, and was not constant worldwide. Other, rare transcripts were reported in 666/34561 patients (1.93%). The proportion of rare transcripts was associated with gender (2.27% in females and 1.69% in males) and with age (from 1.79% in children and adolescents up to 3.84% in patients ≥ 80 years old). These data show that the differences in proportion are not by chance. This is important, as the transcript type is a variable that is suspected to be of prognostic importance for response to treatment, outcome of treatment, and rate of treatment-free remission
