Article Synopsis
- The study aimed to map conditions from a multimorbidity-weighted index (MWI) to ICD-10 codes, creating a new MWI-ICD10 and updating MWI-ICD9 for consistency assessment.
- Conducted at a large medical center from 2013 to 2017, the research involved adults aged 18 and older, analyzing their health encounters over a four-year period.
- Results showed that MWI-ICD10 closely mirrored the prevalence of chronic conditions found in MWI-ICD9, with minimal differences during the transition from ICD-9 to ICD-10, suggesting this new index effectively measures multimorbidity in health records.
Significance Statement: Hispanic patients are known to have a higher risk of kidney failure and lower rates of home dialysis use and kidney transplantation than non-Hispanic White patients. However, it is unknown whether these outcomes differ within the Hispanic community, which is heterogeneous in its members' places of origins. Using United States Renal Data System data, the authors found similar adjusted rates of home dialysis use for patients originating from places outside the United States and US-born Hispanic patients, whereas the adjusted risk of mortality and likelihood of transplantation differed depending on place (country or territory) of origin.

Many of these interventions are modeled after practice-level complex care management (CCM) programs. The authors hypothesized that a national CCM program may be effective for some subgroups of HNHC patients, and the overall null effect may obfuscate subgroup-level impact.
View Article and Find Full Text PDFBackground: High-cost high-need patients are typically defined by risk or cost thresholds which aggregate clinically diverse subgroups into a single 'high-need high-cost' designation. Programs have had limited success in reducing utilization or improving quality of care for high-cost high-need Medicaid patients, which may be due to the underlying clinical heterogeneity of patients meeting high-cost high-need designations.
Methods: Our objective was to segment a population of high-cost high-need Medicaid patients (N = 676,161) eligible for a national complex case management program between January 2012 and May 2015 to disaggregate clinically diverse subgroups.
Background: Medical, behavioral, and social determinants of health are each associated with high levels of emergency department (ED) visits and hospitalizations.
Objective: The objective of this study was to evaluate a care coordination program designed to provide combined "whole-person care," integrating medical, behavioral, and social support for high-cost, high-need Medicaid beneficiaries by targeting access barriers and social determinants.
Research Design: Individual-level interrupted time series with a comparator group, using person-month as the unit of analysis.
