In mixture experiments, estimation of the parameters is generally based on ordinary least squares (OLS). However, in the presence of multicollinearity and outliers, OLS can result in very poor estimates. In this case, effects due to the combined outlier-multicollinearity problem can be reduced to certain extent by using alternative approaches. One of these approaches is to use biased-robust reg...

With hospital services comprising an important part of care related to acquired immunodeficiency syndrome (AIDS), and all Medicaid programs becoming major payers of these services, Medicaid policies affect the care that Medicaid recipients with AIDS receive. Many States pay hospitals on the basis of prospective payments that do not vary with patient diagnosis. In contrast, Medicaid programs usi...

BackgroundLaparoscopic cholecystectomy (LC) is a common procedure for cholelithiasis paid by diagnostic-related groups (DRGs) systems. However, acute cholecystitis (AC) patients usually have heterogeneous conditions that compromise the successful implementation of DRGs. We evaluated quality/efficiency treating AC under DRG system in Taiwan.MethodsAll who underwent LC between October 2015 and De...

Cost estimation is important in assessing a health system’s performance. However, most of the costing system that presently exists presumes that all patients consume exactly the same amount of resources, and little attention is paid to costs at the patient level. Thailand has used Thai DRG for the prospective payment of inpatient care with a closed end, but there is a growing need to have patie...

Background . In 2021, new clinical guidelines for the treatment of chronic hepatitis C virus (HCV) in adults were published that did not contain interferon drug therapy regimens. Current HCV is based on modern drugs direct-acting antivirals (DAA). this regard, model diagnosis-related groups (DRG) with use interferon-containing as etiotropic therapy, which has been effect until now, lost its rel...

In order to provide tailor-made care, governments are considering the implementation of output-pricing based on hospital case-mix measures, such as diagnosis related groups (DRG). The question is whether the current DRG classification system can provide a satisfactory prediction of the variance of costs in stroke patients and if not, in what way other variables may enhance this prediction. In t...

BACKGROUND There is a need to develop other casemix classifications, apart from DRG for sub-acute and non-acute inpatient care payment mechanism in Thailand. OBJECTIVE To develop a casemix classification for sub-acute and non-acute inpatient service. MATERIAL AND METHOD The study began with developing a classification system, analyzing cost, assigning payment weights, and ended with testing...
