Adapting the HCUP QIs for hospital use: the experience in New York State.

BACKGROUND: The Agency for Healthcare Research and Quality developed the Healthcare Cost and Utilization Project (HCUP) quality indicators (QIs) in 1994. The Healthcare Association of New York State (HANYS; Albany), which represents more than 500 nonprofit and public hospitals, long-term care facilities, and home health care agencies, has adapted the HCUP QIs since 1997 to produce annual comparative reports for its member hospitals. Specifically designed for internal use, the reports have been well received and have drawn interest from other hospital associations and state health departments. METHODS: The HCUP QIs were applied to the New York State hospital discharge abstract. A risk adjustment model was constructed for each complication measure. Measures of utilization and access to care were adjusted for differences in patient demographics and payer status by indirect standardization. Data are presented in graphic format. Each hospital receives its own report (in both paper copy and CD-ROM) with comparisons to statewide norms, regional averages, and peer group averages. Report prepared for hospital systems include data for each affiliated hospital. CONCLUSIONS: When used appropriately, the HCUP QIs provide valuable information for individual hospitals to assess quality of care and target potential areas for improvement. The HCUP QIs also give hospitals a broad perspective to look beyond their own institutions and develop community-based quality improvement initiatives. Nevertheless, given the limitations that commonly exist with administrative databases and the lack of standard risk adjustment systems, the HCUP QIs are best used for internal purposes and not for public reporting.

Factors affecting innovation in pediatric surgery: hospital type and appendectomies.

BACKGROUND: There are little data on whether patient or hospital characteristics affect utilization of innovative surgical techniques in children, especially with respect to laparoscopic appendectomy (LA), whose benefit over existing treatment remains unproven. This study examines the patterns of LA using a national database, focusing on variations in care between children's and general hospitals. METHODS: Using data from the 2000 Healthcare Costs and Utilization Project Kid's Inpatient Database for patients aged 5 to 20 years with a discharge diagnosis of appendectomy, we analyzed the relationship between LA and patient demographic and hospital characteristic variables. RESULTS: The Healthcare Costs and Utilization Project Kid's Inpatient Database included 50,825 pediatric appendectomies (26% LA) representing 97,205 cases in the nation. Children's hospitals and children's units were significantly more likely to provide LA (36% and 28%, respectively) than general hospitals (25%). Higher LA rates were also associated with greater patient age, female sex, nonperforated appendicitis, private insurance, and white patient race. The children's hospital effect compared to general hospitals (adjusted odds ratio, 2.11; 95% confidence interval, 1.88-2.38) and all other relationships remained significant in the multivariate model. CONCLUSION: Utilization of LA is significantly higher in children's hospitals. Children's hospitals appear more likely to adopt innovative surgical procedures, such as LA, even when clear benefit over standard treatment has not yet emerged.

Capitating home health care.

Managed care is beginning to make inroads into home health care, and more home healthcare providers are signing capitation contracts. Unfortunately, a lack of home healthcare cost and utilization data has made it difficult to set reasonable capitation rates. In addition, home healthcare providers currently have little control over care management and, therefore, cannot effectively manage utilization under capitation. They also are unused to thinking in terms of controlling utilization and guaranteeing services for a predetermined population at a preset price. In the long run, however, home healthcare providers and payers that develop cooperative working relationships will find ways to collect and share the information they need to make these arrangements mutually successful.

The effect of increases in HMO penetration and changes in payer mix on in-hospital mortality and treatment patterns for acute myocardial infarction.

OBJECTIVE: To determine whether changes in health maintenance organization (HMO) penetration or payer mix affected in-hospital mortality and treatment patterns of patients with acute myocardial infarction (AMI). STUDY DESIGN: Observational study using patient-level logistic regression analysis and hospital and year fixed effects of data from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project Nationwide Inpatient Sample, a geographically diverse sample of 20% of the hospitalized patients in the United States. PATIENTS AND METHODS: Discharges of patients (n = 340,064) with a primary diagnosis of acute myocardial infarction who were treated in general medical or surgical hospitals that contributed at least 2 years of data to the HealthCare Cost and Utilization Project Nationwide Inpatient Sample from 1989 to 1996. In-hospital mortality and rates of cardiac catheterization, angioplasty, or coronary artery bypass grafting for Medicare patients or non-Medicare patients were the main outcome measures. RESULTS: Among Medicare patients, increases in HMO penetration were associated with reduced odds of receiving cardiac catheterization, angioplasty, or coronary artery bypass grafting of 3% to 16%, but were not associated with any change in mortality risk. Increases in the number of HMOs within a metropolitan statistical area, our measure of HMO competition, were associated with small but significant increases in the odds of cardiac catheterization and angioplasty of about 2%. There was no pattern of changes in cardiac procedure rates or in-hospital mortality among non-Medicare patients. CONCLUSION: Increases in HMO penetration reduced cardiac procedure rates by statistically significant but small amounts among Medicare patients with AMI, without affecting mortality rates.

Patterns of care as a risk factor for the development of vision-threatening diabetic retinopathy: a population-based matched case-control study using insurance claims (Medicare) data.

OBJECTIVES: To evaluate systematically the effectiveness of the primary healthcare system in Australia in preventing the development of advanced diabetes complications. METHODS: Diabetes patients (n = 4632) who had received their first laser photocoagulation treatment in 2000 were compared with a random sample of diabetes patients who had never received this treatment (n = 4632). Patterns of health care utilization were compared over a 7-year period (1993-1999) using the Australian Medicare database. RESULTS: There were significant differences in levels of healthcare utilization: cases were less likely to attend a general practitioner, from odds ratio (OR) = 0.21 (P < 0.0001) in 1993 to 0.53 (P < 0.0001) in 1999; less likely to be tested for HbA(1c), from OR = 0.24 in 1997 (P < 0.0001) to 0.38 in 1999 (P < 0.0001); for HDL-cholesterol, from OR = 0.017 (P < 0.0001) in 1999 to 0.04 (P < 0.0001) in 1993; and to attend specialists and consultant physicians, from OR = 0.25 (P < 0.0001) in 1994 to 0.44 (P < 0.0001) in 1999. The multivariate analysis emphasized the importance of timely diagnosis, HDL-cholesterol testing and optometry attendances in the prevention of advanced diabetes complications. CONCLUSIONS: The study supports the contention that healthcare utilization may be as important a determinant of health outcomes as clinical risk factors such as blood glucose control. This highlights the importance of early diagnosis and the need to address systemic barriers so as to increase primary care utilization for people at risk of advanced diabetes complications.

Conducting research on the Medicare market: the need for better data and methods.

OBJECTIVE: To highlight data limitations, the need to improve data collection, the need to develop better analytic methods, and the need to use alternative data sources to conduct research related to the Medicare program. Objectives were achieved by reviewing existing studies on risk selection in Medicare HMOs, examining their data limitations, and introducing a new approach that circumvents many of these shortcomings. DATA SOURCES: Data for years 1995-97 for five states (Arizona, Florida, Massachusetts, New York, and Pennsylvania) from the Healthcare Cost and Utilization Project (HCUP) State Inpatient Databases (SIDs), maintained by the Agency for Healthcare Research and Quality; and the Health Care Financing Administration's Medicare Managed Care Market Penetration Data Files and Medicare Provider Analysis and Review Files. STUDY DESIGN: Analysis of hospital utilization rates for Medicare beneficiaries in the traditional fee-for-service (FFS) Medicare and Medicare HMO sectors and examination of the relationship between these rates and the Medicare HMO penetration rates. PRINCIPAL FINDINGS: Medicare HMOs have lower hospital utilization rates than their FFS counterparts, differences in utilization rates vary across states, and HMO penetration rates are inversely related to our rough measure of favorable selection. CONCLUSIONS: Substantial growth in Medicare HMO enrollment and the implementation of a new risk-adjusted payment system have led to an increasing need for research on the Medicare program. Improved data collection, better methods, new creative approaches, and alternative data sources are needed to address these issues in a timely and suitable manner.

Severity of illness, race, and choice of local versus distant hospitals among the elderly.

This study examines travel patterns for hospitalization among elderly patients to address whether there are differences by age and race/ethnicity, and whether the differences persist even when a severe illness occurs. Using the Healthcare Cost and Utilization Project (HCUP) State Inpatient database (SID) of the Agency for Healthcare Research and Quality, the study focuses on New York residents in the 65-and-over age group who are hospitalized in New York or neighboring states. Two types of hospital admissions are used: referral-sensitive admissions (fairly discretionary, high-technology procedures) and ambulatory care-sensitive admissions (avoidable with appropriate primary care). The study found that, after adjusting for other covariates, travel progressively declines with age among the elderly. Travel patterns across elderly age cohorts were not significantly different when patients were more severely ill. Members of racial/ethnic minority groups were less likely to travel than whites, and this gap persisted even when a severe illness occurred.

Health care for children and youth in the United States: 2002 report on trends in access, utilization, quality, and expenditures.

OBJECTIVE: To examine changes in insurance coverage, health care utilization, perceived quality of care, and expenditures for children and youth in the United States using data from 1987-2001. METHODS: Three national health care databases serve as the sources of data for this report. The Medical Expenditure Panel Survey (1996-2001) provides data on insurance coverage, utilization, expenditures, and perceived quality of care. The National Medical Expenditure Survey (1987) provides additional data on utilization and expenditures. The Nationwide Inpatient Sample (1995-2000) from the Healthcare Cost and Utilization Project provides information on hospitalizations. RESULTS: The percent of children uninsured for an entire year declined from 10.4% in 1996 to 7.7% in 1999. Most changes in children's health care occurred between 1987 and the late 1990s. Overall utilization of hospital-based services has declined significantly since 1987, especially for inpatient hospitalization. Several of the observed changes from 1987 varied significantly by type of health insurance coverage, poverty status, and geographic region. Quality of care data indicate some improvement between 2000 and 2001, which varies by insurance coverage. Overall, mean length of stay of hospitalizations did not change significantly from 1995 to 2000, but changes in the prevalence of hospitalizations and the length of stay associated with age-specific diagnoses were evident during this time period. CONCLUSIONS: Health care for children and youth has changed significantly since 1987, with most of the changes occurring between 1987 and 1996. Insurance coverage has improved, the site of care has shifted toward ambulatory sites, hospital utilization has declined, and expenditures on children as a proportion of total expenditures have decreased. Variation in these changes is evident by insurance status, poverty, and region.

Development and validation of a psychiatric case-mix system.

BACKGROUND: Although difficulties in applying risk-adjustment measures to mental health populations are increasingly evident, a model designed specifically for patients with psychiatric disorders has never been developed. OBJECTIVE: Our objective was to develop and validate a case-mix classification system, the "PsyCMS," for predicting concurrent and future mental health (MH) and substance abuse (SA) healthcare costs and utilization. SUBJECTS: Subjects included 914,225 veterans who used Veterans Administration (VA) healthcare services during fiscal year 1999 (FY99) with any MH/SA diagnosis (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] codes 290.00-312.99, 316.00-316.99). METHODS: We derived diagnostic categories from ICD-CM codes using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition definitions, clinical input, and empiric analyses. Weighted least-squares regression models were developed for concurrent (FY99) and prospective (FY00) MH/SA costs and utilization. We compared the predictive ability of the PsyCMS with several case-mix systems, including adjusted clinical groups, diagnostic cost groups, and the chronic illness and disability payment system. Model performance was evaluated using R-squares and mean absolute prediction errors (MAPEs). RESULTS: Patients with MH/SA diagnoses comprised 29.6% of individuals seen in the VA during FY99. The PsyCMS accounted for a distinct proportion of the variance in concurrent and prospective MH/SA costs (R=0.11 and 0.06, respectively), outpatient MH/SA utilization (R=0.25 and 0.07), and inpatient MH/SA utilization (R=0.13 and 0.05). The PsyCMS performed better than other case-mix systems examined with slightly higher R-squares and lower MAPEs. CONCLUSIONS: The PsyCMS has clinically meaningful categories, demonstrates good predictive ability for modeling concurrent and prospective MH/SA costs and utilization, and thus represents a useful method for predicting mental health costs and utilization.

Factors associated with increased resource utilization for congenital heart disease.

OBJECTIVE: To identify patient, institutional, and regional factors that are associated with high resource utilization for congenital heart surgery. METHODS: We used hospital discharge data from the Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database (KID) year 2000 (data from 27 states). Patients who had congenital heart surgery and were younger than 18 years were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes. High resource utilization admissions were defined as those in the highest decile for total hospital charges. Univariate and multivariate analyses with and without deaths were used to determine demographic and hospital predictors for cases of high resource use. Case-mix severity was approximated using Risk Adjustment for Congenital Heart Surgery risk groups. Regional and state differences were also examined. RESULTS: Among 10,569 cases of congenital heart surgery identified, median total hospital charges were 53,828 dollars. Statewide differences in the number of high resource use admissions were present; California, Colorado, Florida, Hawaii, Pennsylvania, and Texas were more likely to have high resource use cases, and Maine and South Carolina were less likely. Subsequent analyses were performed adjusting for baseline state effects. Multivariate analyses using generalized estimating equations models revealed Risk Adjustment for Congenital Heart Surgery risk category (odds ratio [OR]: 1.66-14.1), age (OR: 3.81), prematurity (OR: 4.85), the presence of other major noncardiac structural anomalies (OR: 2.53), Medicaid insurance (OR: 1.48), and admission during a weekend (OR: 1.62) to be independent predictors of a higher odds of high cost cases. Although some institutional differences were noted in univariate analyses, gender, race, bed size, teaching and children's hospital status, hospital ownership, and hospital volume of cardiac cases were not independently associated with greater odds of high resource utilization. CONCLUSIONS: States varied in the frequency of high resource utilization for congenital heart surgery. Patients who had greater disease complexity, younger age, prematurity, other anomalies, and Medicaid and were admitted during a weekend were more likely to result in high resource utilization. Institutions of various types did not differ in high cost admissions, regardless of children's hospital or teaching status.

Hospital stays, hospital charges, and in-hospital deaths among infants with selected birth defects--United States, 2003.

Birth defects (BDs) are conditions that 1) result from a malformation, deformation, or disruption in one or more parts of the body; 2) are present at birth; and 3) have a serious, adverse effect on health, development, or functional ability. BDs are leading causes of pediatric hospitalizations, medical expenditures, and infant mortality. To estimate national hospital charges and rates of in-hospital deaths for a greater number of specific BDs than estimated in previous reports, investigators at the University of Arkansas for Medical Sciences and CDC used the Healthcare Cost and Utilization Project 2003 Kids' Inpatient Database (KID), developed and distributed by the Agency for Healthcare Research and Quality. KID is a 10% sample of hospital discharges after uncomplicated births and an 80% sample of all other pediatric discharges from 36 participating states. Data are weighted to represent all pediatric hospitalizations in the United States. The investigators analyzed hospital stays during 2003 for newborn infants with any of 35 BDs. This report describes the results of that analysis, which indicated substantial variation among BDs regarding average length of stay, average hospital charge, and the incidence of in-hospital deaths. Average length of stay was greatest for infants with surgically repaired gastroschisis or omphalocele. Average hospital charges were highest for infants with hypoplastic left heart syndrome and common truncus arteriosus. Although anencephaly, trisomy 13, and trisomy 18 were associated with the highest rates of in-hospital death, the largest total numbers of deaths associated with neonatal hospitalizations occurred in infants with diaphragmatic hernia and renal agenesis. Further studies are needed to distinguish outcomes for infants with isolated and multiple defects and to assess longer-term outcomes.

Guidelines for a curriculum in healthcare quality and resource management.

Issues of quality pervade American society. Demands for accountability for the quality of and the resources utilized in delivering healthcare services are coming from consumer advocacy groups, regulatory agencies, third-party payers, and corporate purchasers of healthcare. To date, institutions of higher education do not consistently offer either adequate or coordinated programs to prepare healthcare professionals to assume the regulator role. Promoting quality is both a mandate and a legacy, and each professional will need to be involved to ensure continuing quality care for consumers. Active collaboration between academic, service, and professional organizations, as well as a strong commitment to the development and timely implementation of a suitable curriculum, are imperative.

Utility of dual skin tests to evaluate tuberculin skin test reactions of 10 to 14 mm in healthcare workers.

OBJECTIVE: To define the utility of 10- to 14-mm reactions to a Mycobacterium tuberculosis purified protein derivative (PPD) skin test for healthcare workers (HCWs). DESIGN: Blinded dual skin testing, using PPD and M. avium sensitin, of HCWs at a single medical center who had a 10- to 14-mm reaction to PPD when tested by personnel from the Occupational Health Department as part of routine annual screening. SETTING: A single tertiary-care academic medical center. PARTICIPANTS: Employees of the medical center who underwent routine annual PPD screening and were identified by the Occupational Health Department as having a reaction of 10 to 14 mm to PPD. RESULTS: Nineteen employees were identified as candidates and 11 underwent dual skin testing. Only 4 (36%) had repeat results for PPD in the 10- to 14-mm range, whether read by Occupational Health Department personnel or study investigators. For only 5 (45%) of the subjects did the Occupational Health Department personnel and study investigators concur (+/- 3 mm) on the size of the PPD reaction. Two of the 4 subjects with reactions of 10 to 14 mm as measured by the study investigators were M. avium sensitin dominant, 1 was PPD dominant, and 1 was nondominant. CONCLUSION: A reaction of 10 to 14 mm to PPD should not be used as an indication for the treatment of latent tuberculosis (TB) infection in healthy HCWs born in the United States with no known exposure to TB.

Health care for children and youth in the United States: 2001 annual report on access, utilization, quality, and expenditures.

OBJECTIVES: To provide an update on insurance coverage, use of health care services, and health expenditures for children and youth in the United States and new information on parents' perceived quality of care for their children and to provide information on variation in hospitalizations for children from a 24-state hospital discharge data source. METHODS: The data on insurance coverage, utilization, expenditures, and perceived quality of care come from the Medical Expenditure Panel Survey. The data on hospitalizations come from the Nationwide Inpatient Sample, which is part of the Healthcare Cost and Utilization Project. Both data sets are maintained by the Agency for Healthcare Research and Quality. RESULTS: In 2000, 64.5% of children were privately insured, 21.6% were insured through public sources, and 13.9% were uninsured. Children aged 15-17 years were more likely to be uninsured than children 1-4 years old. Children without health insurance coverage were less likely to use health care services, and when they did, their rates of utilization and expenditures were lower than insured children. Publicly insured children were the most likely to use hospital inpatient and emergency department (ED) care. Being black or Hispanic and living in families with incomes below 200% of the poverty line were associated with lower utilization and expenditures. A small proportion of children account for the bulk of health care expenditures: approximately 80% of all children's health care expenditures are attributable to 20% of children who used medical services. Although most parents report that their experiences with health care for their children are good, there are significant variations by type of insurance coverage. There are substantial differences in average length of hospitalization across the United States, ranging from 2.9-4.1 days, and rates of hospital admission through the ED, which vary across states from 10%-25%. Injuries are a major reason for hospitalization, accounting for 1 in 6 hospital stays among 10- to 14-year-olds. In the 10- to 17-year age group, more than 1 in 7 hospital stays are due to mental disorders. Among 15- to 17-year-olds, more than one third of all hospital stays are related to childbirth and pregnancy. The top 10 most common conditions treated in the hospital account for 40%-60% of all hospital stays. CONCLUSION: Children's use of health care services varies considerably by the type of health insurance coverage, race/ethnicity, and family income. Quality of care, as measured by parents' experiences of care, also varies by type of coverage. There is substantial variation in use of hospital services across states.

Lifestyle risk factors predict healthcare costs in an aging cohort.

BACKGROUND: While the U.S. elderly population uses a disproportionate amount of healthcare resources, there is limited knowledge from prospective studies regarding the impact of lifestyle-related factors on costs in this group. The association was examined between smoking, drinking, exercise, body mass index (BMI), and changes in these risk factors, and healthcare costs after 4 years among 68- to 95-year-olds. METHODS: A total of 1323 participants completed annual surveys providing information on lifestyle factors (1986-1994) and health utilization (1994-1998). Healthcare costs in nine categories were ascertained from validated utilization. The relationships between risk factors and costs were examined in 2004 using linear regression models. RESULTS: Fewer cigarette pack-years and lower BMI were the most significant predictors of lower total costs in 1998 (p<0.001), controlling for baseline sociodemographic factors, costs, and conditions. Associations with smoking were strongest for hospitalizations, diagnostic tests, and physician and nursing-home visits. Those who reduced smoking by one pack per day experienced cost savings of 1160 dollars (p<0.05). The costs for normal weight compared to minimally obese seniors were approximately 1548 dollars lower, with diagnostic testing, physician visits, and medications accounting for much of this difference. Daily walking, measured at baseline, also predicted lower costs for hospitalizations and diagnostic testing. CONCLUSIONS: Seniors who were leaner, smoked fewer cigarettes over a lifetime, reduced their smoking, or walked farther had significant subsequent cost savings compared to those with less-healthy lifestyle-related habits.

Annual report on access to and utilization of health care for children and youth in the United States--2000.

OBJECTIVE: This report provides an update on insurance coverage, use of health care services, and health expenditures for children and youth in the United States. In addition, the report provides information on variation in hospitalizations for children from a new 22-state hospital discharge data source. METHODS: The data on insurance coverage, utilization, and expenditures come from the Medical Expenditure Panel Survey. The data on hospitalizations come from the Database for Pediatric Studies, which is part of the Healthcare Cost and Utilization Project. Both data sets have been prepared by the Agency for Healthcare Research and Quality. RESULTS: Few changes in insurance coverage occurred between 1996 and 1998. About two thirds of American children are covered by private insurance and 19% by public sources; the remaining 15% are uninsured. Of the 71.5% of children who have at least 1 doctor's office visit, the average number of visits was 3.9, but this ranged from 2.7 among the uninsured to 4.2 for those with private insurance. Slightly more than half of children had a prescription, and these averaged 5.4 prescriptions. The majority of children (85%) incur medical expenditures, averaging $1019 for children with any expenditure. Private health insurance was by far the largest payer of medical care expenses for children, even more so than among the general population. However, nearly 21% of expenditures for children's health care were paid out of pocket by children's families. The data also show substantial differences in average length of hospitalization across states, ranging from 2.7 to 4.0 days, and rates of hospital admission through the emergency department, which vary across states from 9% to 23%. Injuries are a major reason for hospitalization, accounting for 1 in 6 hospital stays among 10- to 14-year-olds. In the 10-17 age group, 1 in 7 hospital stays are due to mental disorders. Among 15- to 17-year-olds, more than one third of all hospital stays are related to childbirth and pregnancy. CONCLUSION: Children's use of health care services varies considerably by what type of health insurance coverage they have. Expenditures for children entail a substantial out-of-pocket component, which may be quite large for children with major health problems and which may represent a significant burden on lower-income families. Substantial variation in hospitalization exits across states.
