Incidence Rate of Advanced Chronic Kidney Disease Among Privately Insured Adults with Neurodevelopmental Disabilities.

ABSTRACT: Purpose:Due to complex medical profiles, adults with neurodevelopmental disabilities (NDDs) may have a heightened risk for early development of chronic kidney disease (CKD) and accelerated CKD progression to advanced stages and kidney failure. The purpose of this study was to estimate the incidence rate of advanced CKD for adults with NDDs and compare the incidence rate to adults without NDDs. Patients and Methods:Data were used from the Optum Clinformatics® Data Mart to conduct this retrospective cohort study. The calendar year 2013 was used to identify eligible participants: individuals ?18 years of age and without advanced CKD. Participants were followed from 01/01/2014 to advanced CKD, loss to follow-up, death, or end of the study period (12/31/2017), whichever came first. Diagnostic, procedure, and diagnosis-related group codes identified NDDs (intellectual disabilities, cerebral palsy, autism spectrum disorders), incident cases of advanced CKD (CKD stages 4+), diabetes, cardiovascular diseases, and hypertension present in the year 2013. Crude incidence rates (IR) of advanced CKD and IR ratios (IRR), comparing adults with vs without NDDs (with 95% CI) were estimated. Then, Cox regression estimated the hazard ratio (HR and 95% CI) for advanced CKD, comparing adults with NDDs to adults without NDDs while adjusting for covariates. Results:Adults with NDDs (n=33,561) had greater crude IR of advanced CKD (IRR=1.32; 95% CI=1.24-1.42) compared to adults without NDDs (n=6.5M). The elevated rate of advanced CKD among adults with NDDs increased after adjusting for demographics (HR=2.19; 95% CI=2.04-2.34) and remained elevated with further adjustment for hypertension and diabetes (HR=2.01; 95% CI=1.87-2.15) plus cardiovascular disease (HR=1.84; 95% CI=1.72-1.97). Stratified analyses showed that the risk of advanced CKD was greater for all NDD subgroups. Conclusion:Study findings suggest that adults with NDDs have a greater risk of advanced CKD than do adults without NDDs, and that difference is not explained by covariates used in our analysis.

Project description:OBJECTIVE:Individuals with paediatric-onset disabilities (PoDs) have complex healthcare needs and are susceptible to adverse health outcomes, which may impose a higher strain on healthcare resources. The burden of healthcare resource utilisation and costs attributed to the population of adults with PoDs is not clearly established. The objective here was to compare healthcare resource utilisation and costs between adults with versus without PoDs. DESIGN:Cohort. SETTING:Data were from the 2016 Optum Clinformatics Data Mart, a de-identified nationwide claims database of beneficiaries from a single private payer in the USA. PARTICIPANTS:International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes were used to identify beneficiaries with PoDs that were between 18 and 64 years of age. PRIMARY AND SECONDARY OUTCOME MEASURES:Annual all-cause healthcare resource utilisation and total healthcare costs were compared between adults with and without PoDs before and after adjusting for sociodemographics and several costly non-communicable diseases. RESULTS:Adults with PoDs (n=121 446) had greater annual mean counts of service utilisation for all service types (eg, inpatient, outpatient, emergency visits) compared with adults without PoDs (n=5 415 475) before and after adjustments (all p<0.001). Adults with PoDs had greater unadjusted total standardised reimbursement costs (US$26 702 vs US$8464; mean difference=US$18 238; cost ratio (CR)=3.16; 95% CI=3.13 to 3.18) and total patient out-of-pocket costs (US$2226 vs US$1157; mean difference=US$1069; CR=1.88; 95%CI=1.86 to 1.89). After adjustments, total standardised reimbursement costs were 2.32 times higher (95% CI=2.30 to 2.34) and total patient out-of-pocket costs were 1.65 times higher (95% CI=1.64 to 1.66) compared with adults without PoDs. CONCLUSION:Adults with PoDs had greater healthcare utilisation and costs, even after accounting for costly diseases. Future research is needed to identify the cost drivers for adults with PoDs.

Project description:Importance:To achieve the World Health Organization goal of viral hepatitis elimination by 2030, it is important to estimate current rates of chronic hepatitis B (CHB) diagnosis and treatment. Objective:To provide an accurate accounting of the number of patients with CHB aged 6 years or older who have not yet been diagnosed in the United States. Design, Setting, and Participants:This cross-sectional study used the commercial US Truven Health MarketScan Database (138 634 154 privately insured individuals in January 2007 to December 2014) to identify patients with CHB diagnosis and the National Health and Nutrition Examination Survey to estimate the actual number of privately insured persons with CHB. Based on sex and age distribution derived from the US Census Bureau, we calculated the total population with CHB and the proportion of those who remained undiagnosed among the 198 073 302 privately insured individuals. Next, we identified diagnosed CHB patients who received 1 or more prescription for CHB medications to calculate the treatment rate for those with severe disease states, such as cirrhosis and hepatocellular carcinoma, that would warrant treatment. Analyses were performed from October 2017 to January 2020. Main Outcomes and Measures:The rate and number of patients with CHB who remained undiagnosed and treatment rates for patients with CHB who have cirrhosis or hepatocellular carcinoma. Results:Among the 198 073 302 privately insured individuals (48.55% male; 15.52% aged 6-17 years; 84.48% aged ≥18 years), there were 511 029 (95% CI, 317 733-704 325) individuals with CHB, but only 95 075 of these had been diagnosed, yielding a diagnosis rate of only 18.60% (95% CI, 13.50%-29.92%), meaning that 81.40% (95% CI, 70.08%-86.50%) were undiagnosed. The treatment rates were 34.79% (95% CI, 33.31%-36.27%) for those with cirrhosis and 48.64% (95% CI, 45.59%-51.69%) for those with hepatocellular carcinoma. Conclusions and Relevance:In this study, only approximately 1 in 5 privately insured patients with CHB had been diagnosed. Only one-third of patients with CHB who had cirrhosis and one-half who had hepatocellular carcinoma received antiviral therapy. Further efforts are needed to improve the current situation of poor connection to care for patients with CHB, especially for those with advanced liver disease.

Project description:OBJECTIVE:To analyze utilization of, and payments for, pelvic organ prolapse procedures after the 2011 U.S. Food and Drug Administration (FDA) communication regarding transvaginal mesh. METHODS:This is a retrospective cohort study examining private claims from three insurance providers for inpatient and outpatient prolapse procedures from 2010 to 2013 in the Health Care Cost Institute. Primary outcomes were the change in utilization of prolapse procedures, with and without mesh, before and after the July 2011 FDA communication. Secondary outcomes were the changes in payments and reimbursements for these procedures. Utilization rates and payments were compared using generalized linear models and interrupted time-series analysis. RESULTS:Utilization of prolapse procedures decreased from 12.3 to 9.7 per 10,000 woman-years (P=.027) with a decrease of 30.7% (3.9 in 2010 to 2.7 in 2013, P=.05) in number of mesh procedures and 16.6% (8.4 in 2010 to 7.0 in 2013, P=.011) for nonmesh procedures. Quarterly utilization of mesh procedures was increasing before the FDA communication and then significantly declined after its release (slope=0.024 vs -0.025, P=.002). Nonmesh procedures, however, were already slightly decreasing before July 2011 and continued to decline at a more rapid pace after that time, although not significantly (slope=-0.004 vs -0.022, P=.47). Inpatient utilization decreased 52.2% (P=.002), whereas outpatient utilization increased 18.5% (P=.132). Payments for individual inpatient procedures, with and without mesh, increased by 12.0% ($8,315 in 2010 to $9,315 in 2013, P=.001) and 15.6% ($7,826 in 2010 to $9,048 in 2013, P=.005), respectively, whereas those for outpatient procedures increased by 41% ($4,961 in 2010 to $6,981 in 2013, P=.006) and 30% ($3,955 in 2010 to $5,149 in 2013, P=.004), respectively. CONCLUSION:Use of prolapse surgery declined during the study period. After the 2011 FDA communication regarding transvaginal mesh, there was a significant decrease in the utilization of procedures with mesh but not for those without mesh. A shift toward outpatient surgeries was observed, and payments for both individual inpatient and outpatient cases increased.
