A Comparison of Techniques for Detecting Cross-Cultural Inequivalence at the Item Level

This paper uses a Monte Carlo study to compare some DIFdetection techniques with respect to their ability to detect uniform aswell as nonuniform item bias.The techniques that are used in the comparison are the loglinearmodel, the logistic regression model, the signed and the unsignedarea between the item characteristic curves, the SOS1 and theSOS3 measure. A first Monte Carlo study was set up to assess theempirical distributions of the unsigned area (in the 2-PLM), theSOS1 and the SOS3 measures. A second simulation study compares all these techniques with respect to their ability to detect DIF. It was alsoinvestigated whether using a two-stage approachyields better results.     

Burden of illness associated with sinusoidal obstruction syndrome/veno-occlusive disease in patients with hematopoietic stem cell transplantation

Aims: Sinusoidal obstruction syndrome (SOS) is a life-threatening complication of hematopoietic stem cell transplantation (HSCT) associated with significant morbidity and mortality. Healthcare utilization, costs, and mortality were assessed in HSCT patients diagnosed with SOS, with and without multi-organ dysfunction (MOD).

Materials and methods: This retrospective observational study identified real-world patients undergoing HSCT between January 1, 2009 and May 31, 2014 using the Premier Healthcare Database. In absence of a formal ICD-9-CM diagnostic code, SOS patients were identified using a pre-specified definition adapted from Baltimore and Seattle criteria and clinical practice. Severe SOS (SOS/MOD) and non-severe SOS (SOS/no-MOD) were classified according to clinical evidence for MOD in the database.

Results: Of the 5,418 patients with a discharge diagnosis of HSCT, 291 had SOS, with 134 categorized as SOS/MOD and 157 as SOS/no-MOD. The remaining 5,127 patients had HSCT without SOS. Overall SOS incidence was 5.4%, with 46% having evidence of MOD. Distribution of age, gender, and race were similar between the SOS cohorts and non-SOS patients. After controlling for hospital profile and admission characteristics, demographics, and clinical characteristics, the adjusted mean LOS was 31.0 days in SOS/MOD compared to 23.9 days in the non-SOS cohort (medians?=?26.9 days vs 20.8 days, p?SOS/MOD patients was $140,653, which was $41,702 higher than the non-SOS cohort (medians?=?$105,749 vs $74,395, p?SOS/MOD compared to the non-SOS cohort (odds ratio?=?5.88; 95% CI?=?3.45–10.33).

Limitations: Limitations of retrospective observational studies apply, since the study was not randomized. Definition for SOS was based on ICD-9 diagnosis codes from a hospital administrative database and reliant on completeness and accuracy of coding.

Conclusions: Analysis of real-world data shows that SOS/MOD is associated with significant increases in healthcare utilization, costs, and inpatient mortality.     

The Performance of Some Observed and Unobserved Conditional Invariance Techniques for the Detection of Differential Item Functioning

The current research investigates the performance of some conditional and unconditional invariance measures of differential item functioning (DIF), namely: the log-linear model, the logistic regression model, the signed and the unsigned area, the SOS1 and the SOS3. A simulation study is used to evaluate their ability to detect uniform as well as nondirectional nonuniform DIF under several test conditions. The factors that were subject to experimental manipulation in the simulation study are the size of the DIF, the ability distribution of the focal and the reference group, the sample size, the proportion of DIF items and the length of the test.
