Preventable hospitalizations among children in California counties after child health insurance expansion initiatives

Association Between the COI and Excess Health Care Utilization and Costs for ACSC

BACKGROUND AND OBJECTIVES

The authors of previous work have associated the Childhood Opportunity Index (COI) with increased hospitalizations for ambulatory care sensitive conditions (ACSC). The burden of this inequity on the health care system is unknown. We sought to understand health care resource expenditure in terms of excess hospitalizations, hospital days, and cost.

METHODS

We performed a retrospective cross-sectional study of the Pediatric Health Information Systems database, including inpatient hospitalizations between January 1, 2016 and December 31, 2022 for children <18 years of age. We compared ACSC hospitalizations, mortality, and cost across COI strata.

RESULTS

We identified 2 870 121 hospitalizations among 1 969 934 children, of which 44.5% (1 277 568/2 870 121) were for ACSCs. A total of 49.1% (331 083/674 548) of hospitalizations in the very low stratum were potentially preventable, compared with 39.7% (222 037/559 003) in the very high stratum (P < .001). After adjustment, lower COI was associated with higher odds of potentially preventable hospitalization (odds ratio 1.18, 95% confidence interval [CI] 1.17-1.19). Compared with the very high COI stratum, there were a total of 137 550 (95% CI 134 582-140 517) excess hospitalizations across all other strata, resulting in an excess cost of $1.3 billion (95% CI $1.28-1.35 billion). Compared with the very high COI stratum, there were 813 (95% CI 758-871) excess deaths, with >95% from the very low and low COI strata.

CONCLUSIONS

Children with lower neighborhood opportunity have increased risk of ACSC hospitalizations. The COI may identify communities in which targeted intervention could reduce health care utilization and costs.

Effects of the Children's Health Insurance Reauthorization Act on immigrant children's healthcare access

OBJECTIVE

To estimate the effects of Children's Health Insurance Reauthorization Act (CHIPRA), a policy that provided states the option to extend Medicaid/CHIP eligibility to immigrant children who have not been legal residents for five years or more, on insurance coverage, access, utilization, and health outcomes among immigrant children.

DATA SOURCES

Restricted use 2000-2016 National Health Interview Survey (NHIS).

STUDY DESIGN

We used a difference-in-differences design that compared changes in CHIPRA expansion states to changes in non-expansion states.

DATA COLLECTION

Our sample included immigrant children who were born outside the US, aged 0-18 with family income below 300% of the Federal Poverty Level (FPL). Subgroup analyses were conducted across states that did and did not have a similar state-funded option prior to CHIPRA (state-funded vs. not state-funded), by the length of time in the US (5 years vs. 5-14 years), and global region of birth (Latin American vs. Asian countries).

PRINCIPLE FINDINGS

We found that CHIPRA was associated with a significant 6.35 percentage point decrease in uninsured rates (95% CI: -11.25, -1.45) and an 8.1 percentage point increase in public insurance enrollment for immigrant children (95% CI: 1.26, 14.98). However, the effects of CHIPRA became small and statistically not significant 3 years after adoption. Effects on public insurance coverage were significant in states without state-funded programs prior to CHIPRA (15.50 percentage points; 95% CI:8.05, 22.95) and for children born in Asian countries (12.80 percentage points; 95% CI: 1.04, 24.56). We found no significant changes in health care access and utilization, and health outcomes, overall and across subgroups due to CHIPRA.

CONCLUSIONS

CHIPRA's eligibility expansion was associated with increases in public insurance coverage for low-income children, especially in states where CHIPRA represented a new source of coverage versus a substitute for state-funded coverage. However, we found evidence of crowd-out in certain subgroups and no effect of CHIPRA on access to care and health. Our results suggest that public coverage may be an important tool for promoting the well-being of immigrant children but other investments are still needed.

Parent and Physician Qualitative Perspectives on Reasons for Pediatric Hospital Readmissions

OBJECTIVES

One in 5 parents report a problem in their child's hospital-to-home transition, leading to adverse events, dissatisfaction, and readmissions. Although researchers in several studies have explored parent insights into discharge needs, few have explored perceptions of causes for pediatric readmissions. We sought to investigate factors contributing to pediatric readmissions, from both parent and physician perspectives.

METHODS

We conducted a qualitative study using semistructured interviews with parents, discharging and readmitting physicians, and subspecialist consultants of children readmitted within 30 days of initial discharge from the pediatric ward at an urban nonfreestanding children's hospital. Participants were interviewed during the readmission and asked about care transition experiences during the initial admission and potential causes and preventability of readmission. Data were analyzed iteratively by using a constant-comparative approach. We identified major themes, solicited feedback, and inferred relationships between themes to develop a conceptual model for preventing readmissions.

RESULTS

We conducted 53 interviews from 20 patient readmissions, including 20 parents, 20 readmitting physicians, 11 discharging physicians, and 3 consulting subspecialists. Major themes included the following: (1) unclear roles cause lack of ownership in patient care tasks, (2) lack of collaborative communication leads to discordant understanding of care plans, and (3) incomplete hospital-to-home transitions result in ongoing reliance on the hospital.

CONCLUSIONS

Clear definition of team member roles, improved communication among care team members and between care teams and families, and enhanced care coordination to facilitate the hospital-to-home transition were perceived as potential interventions that may help prevent readmissions.

California's Health4All Kids Expansion And Health Insurance Coverage Among Low-Income Noncitizen Children

More than one-third of US children receive coverage through Medicaid and the Children's Health Insurance Program (CHIP), but undocumented immigrant children are not eligible for public coverage in most states. California's May 2016 Health4All Kids coverage expansion allowed children with qualifying household incomes to enroll in Medi-Cal, California's Medicaid and CHIP program, regardless of their immigration status. We examined the effects of California's expansion on noncitizen children's uninsurance rates and sources of coverage, using data from the 2012-18 American Community Survey. California's expansion was associated with significant increases of about 9 and 12 percentage points in any coverage and public coverage, respectively. The estimated increase in any coverage translates to a 34 percent decline in the uninsurance rate relative to the preexpansion rate among noncitizen children (26 percent). Counties with an existing program to reduce children's uninsurance rates experienced an increase in coverage earlier than those without a program in effect before the statewide expansion.

Pollution, Poverty, and Potentially Preventable Childhood Morbidity in Central California

OBJECTIVE

To measure ecological relationships between neighborhood pollution burden, poverty, race/ethnicity, and pediatric preventable disease hospitalization rates.

STUDY DESIGN

Preventable disease hospitalization rates were obtained from the 2012 California Office of Statewide Health Planning and Development database, for 8 Central Valley counties. US Census Data was used to incorporate zip code level factors including racial diversity and poverty rates. The pollution burden score was calculated by the California Office of Environmental Health Hazard Assessment using 11 indicators. Poisson-based negative binomial regression was used for final analysis. Stratification of sample by age, race/ethnicity, and insurance coverage was also incorporated.

RESULTS

Children experiencing potentially preventable hospitalizations are disproportionately low income and under the age of 4 years. With every unit increase in pollution burden, preventable disease hospitalizations rates increase between 21% and 32%, depending on racial and age subgroups. Although living in a poor neighborhood was not associated with potentially avoidable hospitalizations, children enrolled in Medi-Cal who live in neighborhoods with lower pollution burden and lower levels of poverty, face 32% lower risk for ambulatory care sensitive condition hospitalization. Children living in primary care shortage areas are at increased risk of preventable hospitalizations. Preventable disease hospitalizations increase for all subgroups, except white/non-Hispanic children, as neighborhoods became more racially diverse.

CONCLUSIONS

Understanding the geographic distribution of disease and impact of individual and community level factors is essential to expanding access to care and preventive resources to improve the health of children in California's most polluted and underserved region.

Hospital charges of potentially preventable pediatric hospitalizations

OBJECTIVES

Reducing the number of preventable hospitalizations represents a possible source of health care savings. However, the current literature lacks a description of the extent of potentially preventable pediatric hospitalizations. The study objectives are to (1) identify the charges and (2) demographic characteristics associated with potentially preventable pediatric hospitalizations.

METHODS

Secondary analysis of the 2006 Kids' Inpatient Database (weighted N = 7,558,812). International Classification of Diseases, Ninth Revision, Clinical Modification codes for 16 previously validated pediatric ambulatory care-sensitive (ACS) conditions identified potentially preventable hospitalizations; seven additional conditions reflected updated care guidelines. Outcome variables included number of admissions, hospitalization days, and hospital charges. Demographic and diagnostic variables associated with an ACS condition were compared with regression analyses by the use of appropriate person-level weights.

RESULTS

Pediatric ACS hospitalizations totaled $4.05B in charges and 1,087,570 hospitalization days in 2006. Two respiratory conditions-asthma and bacterial pneumonia-comprised 48.4% of ACS hospital charges and 46.7% of ACS hospitalization days. In multivariate analysis, variables associated with an ACS condition included: male gender (odds ratio [OR] 1.10; 95% confidence interval [95% CI] 1.07-1.13); race/ethnicity of black (OR 1.22; 95% CI 1.16-1.27) or Hispanic (OR 1.12; 95% CI 1.06-1.18); and emergency department as admission source (OR 1.37; 95% CI 1.27-1.48).

CONCLUSIONS

Respiratory conditions comprised the largest proportion of potentially preventable pediatric hospitalizations, totaling as much as $1.96B in hospital charges. Children hospitalized with an ACS condition tend to be male, non-white, and admitted through the emergency department. Future research to prevent pediatric hospitalizations should examine targeted interventions in the primary care setting, specifically around respiratory conditions and minority populations.

Expanding the uses of AHRQ's prevention quality indicators: validity from the clinician perspective

BACKGROUND

The Agency for Healthcare Research and Quality's prevention quality indicators (PQIs) are used as a metric of area-level access to quality care. Recently, interest has expanded to using the measures at the level of payer or large physician groups, including public reporting or pay-for-performance programs. However, the validity of these expanded applications is unknown.

RESEARCH DESIGN

We conducted a novel panel process to establish face validity of the 12 PQIs at 3 denominator levels: geographic area, payer, and large physician groups; and 3 uses: quality improvement, comparative reporting, and pay for performance. Sixty-four clinician panelists were split into Delphi and Nominal Groups. We aimed to capitalize on the reliability of the Delphi method and information sharing in the Nominal group method by applying these techniques simultaneously. We examined panelists' perceived usefulness of the indicators for specific uses using median scores and agreement within and between groups.

RESULTS

Panelists showed stronger support of the usefulness of chronic disease indicators at the payer and large physician group levels than for acute disease indicators. Panelists fully supported the usefulness of 2 indicators for comparative reporting (asthma, congestive heart failure) and no indicators for pay-for-performance applications. Panelists expressed serious concerns about the usefulness of all new applications of 3 indicators (angina, perforated appendix, dehydration). Panelists rated age, current comorbidities, earlier hospitalization, and socioeconomic status as the most important risk-adjustment factors.

CONCLUSIONS

Clinicians supported some expanded uses of the PQIs, but generally expressed reservations. Attention to denominator definitions and risk adjustment are essential for expanded use.
