Trends in diagnosis rates for autism and ADHD at hospital discharge in the context of other psychiatric diagnoses.

OBJECTIVE: Concerns have been raised over observed increases in the number of children who are given a diagnosis of a neurodevelopmental disorder. The goal of this study was to examine trends by age and calendar year in the diagnosis of two of these disorders, autism and attention-deficit hyperactivity disorder (ADHD), in the context of other psychiatric disorders in a sample of hospitalized children. METHODS: Data from the Healthcare Cost and Utilization Project (HCUP) were used for descriptive analyses of secular trends of diagnosed psychiatric disorders between 1989 and 2000. Changes over time in rates of diagnosis of autism, ADHD, affective disorders, and substance-related disorders were examined and compared. RESULTS: Substance-related disorders were the most common mental disorders recorded at hospital discharge and increased by 39 percent between 1989 and 2000. Affective disorder was the next most common diagnosis and increased by 138 percent. Although autism and ADHD were far less common, their diagnosis rates nearly quadrupled over the course of the study. Although rates of diagnosis of affective and substance-related disorders generally increased over the lifespan, diagnosis of autism and ADHD followed a very different pattern, with peaks in rates at ages seven and 12. CONCLUSIONS: Increases in rates of diagnosis of etiologically unrelated mental disorders suggest that there have been changes in diagnostic practices over time, increases in community prevalence of these disorders, and increased likelihood of hospitalizations for different mental disorders.

Incidence and characteristics of total stroke in the United States.

BACKGROUND AND PURPOSE: Stroke, increasingly referred to as a "brain attack", is one of the leading causes of death and the leading cause of adult disability in the United States. It has recently been estimated that there were three quarters of a million strokes in the United States in 1995. The aim of this study was to replicate the 1995 estimate and examine if there was an increase from 1995 to 1996 by using a large administrative claims database representative of all 1996 US inpatient discharges. METHODS: We used the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, release 5, which contains approximately 20 percent of all 1996 US inpatient discharges. We identified stroke patients by using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes from 430 to 438, and we compared the 1996 database with that of 1995. RESULTS: There were 712,000 occurrences of stroke with hospitalization (95% CI 688,000 to 737,000) and an estimated 71,000 occurrences of stroke without hospitalization. This totaled 783,000 occurrences of stroke in 1996, compared to 750,000 in 1995. The overall rate for occurrence of total stroke (first-ever and recurrent) was 269 per 100,000 population (age- and sex-adjusted to 1996 US population). CONCLUSIONS: We estimate that there were 783,000 first-ever or recurrent strokes in the United States during 1996, compared to the figure of 750,000 in 1995. This study replicates and confirms the previous annual estimates of approximately three quarters of a million total strokes. This slight increase is likely due to the aging of the population and the population gain in the US from 1995 to 1996.

Regional variation in hospitalization for stroke among Asians/Pacific Islanders in the United States: a nationwide retrospective cohort study.

BACKGROUND: In Asia, stroke incidence varies dramatically from country to country. Little is known about stroke incidence in Asians/Pacific Islanders in the US, where regional heterogeneity in Asian/Pacific Islander sub-populations is great. We sought to characterize both the national and regional incidences of first and recurrent hospitalized acute ischemic stroke, subarachnoid hemorrhage, and intracerebral hemorrhage in Asians/Pacific Islanders compared to non-Hispanic whites. METHODS: We used the National Inpatient Sample of the 1997 Healthcare Cost and Utilization Project. It is a 20% stratified sample of hospitalizations to nonfederal hospitals in the US. National and regional projections were made using sampling weights specific for patients and hospitals. We identified stroke subtypes using previously validated ICD-9 codes. Age-adjusted incidence rates were calculated using the direct method with the US population in 2000 as the standard. RESULTS: There were 169,386 stroke hospitalizations in the database. Nationally, compared to whites, Asians/Pacific Islanders were more likely to have subarachnoid hemorrhage (incidence rate ratio {RR} female: 1.53, 95% CI 1.41-1.65; male RR: 1.13, 95% CI 1.00-1.27) and intracerebral hemorrhage (female RR 1.29, 95% CI 1.22-1.36; male RR: 1.58, 95% CI 1.50-1.67). However, when examined by geographic regions, Asians/Pacific Islanders had higher incidence rates of subarachnoid hemorrhage and intracerebral hemorrhage predominantly in the West, and lower rates of stroke elsewhere. CONCLUSION: Stroke incidence varies 3-fold among Asians/Pacific Islanders residing in different US regions. Geographic variation is less dramatic in whites. Whether genetic or cultural differences are responsible for dramatic heterogeneity among Asian/Pacific Islander populations is unclear and deserves further study.

Health care utilization among Medicare-Medicaid dual eligibles: a count data analysis.

BACKGROUND: Medicare-Medicaid dual eligibles are the beneficiaries of both Medicare and Medicaid. Dual eligibles satisfy the eligibility conditions for Medicare benefit. Dual eligibles also qualify for Medicaid because they are aged, blind, or disabled and meet the income and asset requirements for receiving Supplement Security Income (SSI) assistance. The objective of this study is to explore the relationship between dual eligibility and health care utilization among Medicare beneficiaries. METHODS: The household component of the nationally representative Medical Expenditure Panel Survey (MEPS) 1996-2000 is used for the analysis. Total 8,262 Medicare beneficiaries are selected from the MEPS data. The Medicare beneficiary sample includes individuals who are covered by Medicare and do not have private health insurance during a given year. Zero-inflated negative binomial (ZINB) regression model is used to analyse the count data regarding health care utilization: office-based physician visits, hospital inpatient nights, agency-sponsored home health provider days, and total dental visits. RESULTS: Dual eligibility is positively correlated with the likelihood of using hospital inpatient care and agency-sponsored home health services and the frequency of agency-sponsored home health days. Frequency of dental visits is inversely associated with dual eligibility. With respect to racial differences, dually eligible Afro-Americans use more office-based physician and dental services than white duals. Asian duals use more home health services than white duals at the 5% statistical significance level. The dual eligibility programs seem particularly beneficial to Afro-American duals. CONCLUSION: Dual eligibility has varied impact on health care utilization across service types. More utilization of home healthcare among dual eligibles appears to be the result of delayed realization of their unmet healthcare needs under the traditional Medicare-only program rather than the result of overutilization in response to the expanded benefits of the dual eligibility program. The dual eligibility program is particularly beneficial to Asian and Afro-American duals in association with the provision of home healthcare and dental benefits.

Admission to acute care hospitals for adolescent substance abuse: a national descriptive analysis.

BACKGROUND: Use of alcohol and illicit drugs by adolescents remains a problem in the U.S. Case identification and early treatment can occur within a broad variety of healthcare and non-healthcare settings, including acute care hospitals. The objective of this study is to describe the extent and nature of adolescent admissions to the acute inpatient setting for substance abuse (SA). We use the Agency for Healthcare Research and Quality (AHRQ) 2000 Healthcare Cost and Utilization Project Kids Inpatient Database (HCUP-KID) which includes over 2.5 million admissions for youth age 20 and under to 2,784 hospitals in 27 states in the year 2000. Specifically, this analysis estimates national number of admissions, mean total charges, and mean lengths of stay for adolescents between the ages of 12 and 17 admitted to an acute care hospital for the following diagnostic categories from the AHRQ's Clinical Classifications Software categories: "alcohol-related mental disorders" and "substance-related mental disorders". Frequency and percentage of total admissions were calculated for demographic variables of age, gender and income and for hospital characteristic variables of urban/rural designation and children's hospital designation. RESULTS: SA admissions represented 1.25 percent of adolescent admissions to acute care hospitals. Nearly 90 percent of the admission occurred in non-Children's hospitals. Most were for drug dependence (38%) or non-dependent use of alcohol or drugs (35%). Costs were highest for drug dependence admissions. Nearly half of admissions had comorbid mental health diagnoses. Higher rates of admission were seen in boys, in older adolescents, and in "self-pay" patients. Alcohol and drug rehabilitation/detoxification, alone or in combination with psychological and psychiatric evaluation and therapy, was documented for 38 percent of admissions. Over 50 percent of cases had no documentation of treatment specific to substance use behavior. CONCLUSION: General acute care hospitals have a significant and important opportunity to recognize, treat, and refer adolescents with substance abuse problems. These results suggest that inpatient facilities should develop and implement policies and processes to ensure that adolescent substance abusers admitted to their institutions receive appropriate care during the admission and appropriate referral to community care resources.

Asian/Pacific Islander American women: age and death rates during hospitalization for breast cancer.

PURPOSE/OBJECTIVES: To investigate whether differences in age and death rates exist between hospitalized Asian/Pacific Islander American (APIA) women and women of other racial groups. DESIGN: Secondary data analysis of a national data set. SETTING: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample, Release 6, was used to obtain hospitalization data on women with breast cancer based on racial status. A total of 20,507 hospitalization records met the study criteria. SAMPLE: All women who were hospitalized with a primary diagnosis of breast cancer, were older than 18, and did not die during hospitalization, plus all women who met the criteria stated above but died during hospitalization. METHODS: Secondary data analysis. Post hoc analysis was used to identify significant differences among racial groups. FINDINGS: Significant differences were found between APIA and Caucasian and Latino women. Significant differences based on race were found between subjects who had died during hospitalization. On average, APIA women were the youngest to die. CONCLUSIONS: APIA women with breast cancer were among the youngest women being hospitalized and the youngest to die during hospitalization. IMPLICATIONS FOR NURSING: Cultural awareness by nurses is critical when discussing methods for prevention and early detection of breast cancer with minority women. Targeting new immigrants is a priority for those who screen and educate women about detection and treatment of breast cancer.

Predictors of hospital length of stay and cost in patients with intracerebral hemorrhage.

We used the 2002 Healthcare Cost and Utilization Project Nationwide Inpatient Sample to assess hospital length of stay (LOS) and cost among adults with a principal diagnosis of intracerebral hemorrhage (n = 13,239). Sixty-nine percent of patients were aged > or =65 years, and 31% died during hospitalization. Mean LOS (cost) was 7.7 days (15,256 dollars) (survivors: 9.6 days, 17,442 dollars). Patient, hospital, and payer characteristics accounted for 69.1% of variation in cost per discharge.

In-hospital mortality following carotid endarterectomy.

OBJECTIVES: To determine population-based estimates of in-hospital mortality following carotid endarterectomy (CEA) and identify potential risk factors for in-hospital death. METHODS: Data from the Healthcare Cost and Utilization Project (HCUP-3) were analyzed for the year 1993. Nationally representative estimates of risk were calculated by age, sex, race, income, census region, hospital location (urban versus rural), teaching status of hospital, number of hospital beds, hospital ownership, third-party payer, principal procedure, and presence of surgical complications. Multivariate models were developed using stepwise logistic regression and a logit model fit by generalized estimating equations. RESULTS: There were 228 deaths among 18,510 CEAs performed in 17 states of the United States in 1993, yielding an estimated in-hospital mortality rate of 1.2%. Multivariate analysis showed that age, principal procedure, and presence of any surgical complication were significant predictors of in-hospital mortality. Mortality increased with increasing age (from 0.9% in those younger than 65 years to 1.7% in those age 75 and older) and was markedly higher with CEA performed as a secondary procedure (6.1% versus 0.9%) or with any surgical complication (5.9% versus 0.9%). CONCLUSIONS: Increasing age, CEA performed as a secondary procedure, and surgical complications are important predictors of in-hospital mortality following CEA.

Point-of-care testing: an introduction.

OBJECTIVE: To review available literature and provide perspective on point-of-care testing, focusing on the impact it has on treatment outcomes in patient care, the impact it has on the costs of patient care, and the role it has in the delivery of pharmaceutical care. DATA SOURCES: Information was retrieved from MEDLINE English literature searches using PubMed (1965-August 2003) and included search terms of point-of-care testing, near patient testing, pharmaceutical care, pharmacists, outcomes, and economics. Additionally, references from retrieved articles were reviewed to identify literature not detected by literature searches. STUDY SELECTION AND DATA EXTRACTION: Comparative studies, demonstration project reports, and systematic reviews were selected. Other related resources, such as government documents, relevant legislation, and government regulations, were included. Emphasis was placed on comparative studies and demonstration project reports. In the absence of these data, other resources were included. DATA SYNTHESIS: Point-of-care testing devices and technology are increasingly used in the delivery of care and therapeutic decision making. No studies have evaluated the impact of point-of-care testing, by itself, on patient care and outcomes. All studies have incorporated point-of-care testing with changes in the way patient care is delivered and have shown significant improvements when this approach is taken. The cost of point-of-care testing is greater than traditional laboratory testing, but the increased cost may be offset by improvements in the management of patient care, improvements in patient outcomes, and decreased utilization of the healthcare system. Point-of-care testing has been used successfully by pharmacists in disease management programs. Various government regulations and legislation impact the use of point-of-care testing. CONCLUSIONS: Limited data indicate that point-of-care testing, when combined with changes in healthcare delivery systems, may improve patient outcomes and decrease the overall cost of health care. Pharmacists have used point-of-care testing in programs designed to improve patient care but must carefully consider regulations and laws that govern the use of these devices. There is a great need for additional investigation into the use of point-of-care testing in patient care.

Preventable hospitalization and medicaid managed care: does race matter?

This study examines the preventable hospitalization patterns of Medicaid patients by race/ethnicity to determine whether Medicaid managed care (MMC) has been more effective in some subgroups than others. It uses logistic models for three states, comparing preventable hospitalizations with marker admissions (urgent admissions, insensitive to primary care). Hospital discharge data from the Healthcare Cost and Utilization Project State Inpatient database of the Agency for Health Care Research and Quality for New York, Pennsylvania, and Wisconsin residents aged 20-64 years is used. In a more urban state, New York, MMC was effective for Whites but not for minorities. In a more rural state, Wisconsin, MMC was effective for minorities. Overall, the evidence is not strong that any particular racial group consistently benefited from MMC, or that any state consistently showed a favorable impact of MMC across racial groups. However, racial/ethnic disparity associated with the risk of preventable hospitalization is significantly lower among Medicaid patients than among private fee-for-service patients.

Charges for childhood asthma by hospital characteristics.

BACKGROUND: The ownership, location, and teaching status of hospitals affect their missions, policies, finances, and operations. OBJECTIVE: This study assesses the relationship of hospital ownership, location, and teaching status with charges and length of stay for children with asthma, the most common reason for pediatric admission after birth. METHODS: All 28 545 complete records of patients </=18 years of age with the principal diagnosis asthma in 1994 were extracted from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample, providing a stratified sample of 735 nonfederal, acute-care hospitals in 17 states. Multiple regression analysis on log transformed data was used to calculate mean total charges and average length of stay (ALOS) after adjusting for illness severity and mortality risk (four All Patient Refined-Diagnosis Related Group classes based on secondary diagnoses and procedures); payer (Medicaid, private, uninsured, other); patient age, sex, income (four categories based on ZIP code of residence); state; bed size (three categories varying by location); hospital ownership; location; teaching status; and admission month. RESULTS: Asthma severity did not differ significantly by hospital location or teaching status. Nonprofit hospitals treated a slightly higher proportion of children with major or extreme severity asthma than either public or for-profit hospitals. Urban teaching hospitals treated more children with asthma who lived in low-income neighborhoods, were uninsured, or received Medicaid coverage than urban nonteaching hospitals. For-profit hospitals admitted fewer children with asthma from low-income areas than did public hospitals. The ALOS was 2.5 days and did not differ significantly by hospital ownership, location, or teaching status. However, the mean total charges, after adjusting for all other significant covariates, was higher at for-profit ($4203) than at nonprofit ($3640) or public hospitals ($3620). Average charges also were higher at urban teaching ($4230) and lower at rural institutions ($2910) compared with urban nonteaching hospitals ($3424). CONCLUSIONS: Despite similar ALOS, mean charges for childhood asthma varied significantly by hospital ownership, location, and teaching status. Implications. Additional clinical and outpatient data are needed to study variations in quality of care by hospital characteristics. With the proliferation of investor-owned hospitals, both the reasons for and the impact of higher average charges at for-profit institutions require additional investigation. With the expanding needs of the medically underserved, socially just policies are required for financing hospitals that care for a disproportionate share of economically disadvantaged children.

Hospital-reported medical errors in children.

CONTEXT: Medical errors are an important problem for hospitalized adult inpatients. However, medical errors in children remain comparatively understudied, and published research has been relatively limited. OBJECTIVES: To investigate the national rates of hospital-reported medical errors in pediatric inpatients over the period 1988-1997; and to determine the association of patient and hospital characteristics with the occurrence of hospital-reported medical errors in children. DESIGN, SETTING, AND PATIENTS: A nonconcurrent cohort study of hospitalized nonnewborn pediatric patients in the United States <or=18 years of age. Data from the Healthcare Cost and Utilization Project for the years 1988, 1991, 1994, and 1997 were used for these analyses. MAIN OUTCOME MEASURE: The occurrence of hospital-reported medical errors. RESULTS: The national rate of hospital-reported medical errors in hospitalized children ranged from 1.81 to 2.96 per 100 discharges. These medical error rates were statistically lower in 1988, with the years 1991, 1994, and 1997 not being statistically different from each other. There were no consistent differences in the rates of medical errors when stratified by gender, race, payor status, or median household income of the patient's zip code across years. There was, however, a statistically significant relationship between higher median household income and increasing medical error rates; this trend was consistent across all 4 years. Similarly, children with special medical needs or dependence on a medical technology also had significantly higher rates of hospital-reported medical errors. Although hospital size did not seem to be related to the rate of medical errors, private for-profit hospitals consistently reported lower rates, whereas urban teaching hospitals in all years but 1997 reported higher rates of medical errors. CONCLUSIONS: These data highlight both the strengths and limitations of administrative data in the investigation of medical errors. Substantively, they suggest fruitful areas for additional and more detailed study, notably children with special medical needs.

Patient safety events during pediatric hospitalizations.

OBJECTIVE: Our objective was to describe potential patient safety events for hospitalized children, using the patient safety indicators (PSIs), and examine associations with these events. METHODS: PSI algorithms, developed by researchers at the Agency for Healthcare Research and Quality to identify potential in-hospital patient safety problems using administrative data, were applied to 3.8 million discharge records for children under 19 years from 22 states in the 1997 Healthcare Cost and Utilization Project. Prevalence of PSI events and associations with patient-level and hospital-level characteristics, length of stay, in-hospital mortality, and total charges were examined. RESULTS: The prevalence of pediatric patient safety events is significant with the highest rate found for birth trauma at 1.5 cases per every 100 births. The majority of these events for birth trauma consist of long bone and skull fractures, excluding the clavicle. Compared with records without PSI events, discharges with PSI events had 2- to 6-fold longer lengths of stay, 2- to 18-fold higher rates of in-hospital mortality, and 2- to 20-fold higher total charges. Bivariate and multivariate analyses found that all PSI events except birth trauma were directly associated with factors related to greater severity of illness and large urban teaching institutions. Birth trauma, however, was directly associated with black and Hispanic ethnicity but was not consistently associated with technologically sophisticated teaching institutions. CONCLUSIONS: The prevalence of birth trauma and other potential patient safety events for hospitalized children is high and comparable to hospitalized adults. These events are associated with increased length of stay, in-hospital mortality, and total charges. Associated factors differ significantly for birth trauma compared with other PSI events. Institutional application of the PSIs may be useful to identify processes of care that warrant further evaluation as the health care industry tackles the problem of patient safety, particularly for children.

Pediatric patient safety in hospitals: a national picture in 2000.

OBJECTIVE: To describe potential patient safety events for hospitalized children, examine associated factors, and explore impacts of safety events. METHODS: The newly released Patient Safety Indicators (PSIs), developed by researchers at the Agency for Healthcare Research and Quality to identify potential in-hospital patient safety problems using administrative data, were applied to hospital discharge data. All 5.7 million discharge records for children younger than 19 years from 27 states in the 2000 Healthcare Cost and Utilization Project were analyzed for PSI events. Prevalence of PSI events and associations with patient-level and hospital-level characteristics were examined. Multivariate regression adjusting for patient severity of illness was used to estimate impacts of safety events in terms of excess length of stay, charges, and in-hospital mortality. RESULTS: The prevalence of pediatric patient safety events is significant. PSI events occurred more frequently in the very young and those on Medicaid insurance, some of the most vulnerable hospitalized children. Regression analysis found that almost all PSIs are associated with significant and substantial increases in length of stay, charges, and in-hospital death. Using the estimates derived here and the actual number of cases identified in the 2000 data, we estimate that patient safety events incurred >1 billion dollars in excess charges for children alone in 2000. CONCLUSIONS: Patient safety problems for hospitalized children occur frequently and with substantial impacts to our health care industry. Unmeasurable by this study are the additional "costs" and "burdens" of safety events that our patients are forced to handle. Additional work to describe and quantify better these outcomes in addition to ones measured here can help solidify the "business case" for patient safety efforts.

National hospitalization impact of pediatric all-terrain vehicle injuries.

OBJECTIVE: All-terrain vehicle (ATV) injuries among children represent a significant and growing problem. Although state-level analyses have characterized some aspects of pediatric ATV-related injuries, little information on the national impact on hospitalization is available. This study was designed to characterize more fully the patterns of injury, hospital length of stay, and hospital charges associated with ATV-related injuries, with a nationally representative sample. METHODS: Analyses were based on the 1997 and 2000 Healthcare Cost and Utilization Project Kids' Inpatient Database (KID). The KID is the only national, all-payer database of hospital discharges for children. KID data were weighted to represent all discharges from general hospitals in the United States. Discharges with external cause-of-injury codes consistent with off-road ATV-related injuries were selected, and the affected population was described. Nationally representative rates of ATV-related injuries were calculated, and changes between 1997 and 2000 were documented. RESULTS: An estimated 5292 children were hospitalized because of ATV-related injuries during the 2-year period, and hospitalizations increased 79.1% between 1997 and 2000. Rates of ATV-related hospitalization were highest among adolescent white male subjects, consistent with previous studies. Most patients had hospital lengths of stay of <4 days (68%), but 10% had stays of >8 days. Injury severity varied considerably, with more than one third of patients sustaining moderate to severe injuries. Approximately 1% of hospitalizations resulted in in-hospital deaths. Total hospital charges for this injury mechanism were 74367677 dollars for the 2-year study period. Most of these charges were paid by private insurers. CONCLUSIONS: This study provides evidence supporting recent substantial increases in childhood ATV-related injuries. The hospitalization impact of ATV-related injuries among children is considerable. Our data support the need for ongoing creative attempts to identify effective strategies to decrease ATV injuries among children.

Lengths of stay and costs associated with children's hospitals.

OBJECTIVE: Because of the unique mission of freestanding children's hospitals, higher costs have generally been accepted; however, increasing health care costs and the impetus for outcomes data demand more accountability. For common diagnoses, with respect to quality care indicators, length of stay (LOS), and total charges, we propose to compare freestanding children's hospitals and other hospitals. Our hypothesis is that, for similar diagnoses, freestanding children hospitals will have longer LOSs and higher costs than other hospitals. METHODS: Data were analyzed from the Healthcare Cost and Utilization Project Kids' Inpatient Database 2000. Encounters qualified for evaluation when 1 of the top 3 discharge codes was consistent with pneumonia, gastroenteritis, respiratory syncytial virus, dehydration, or asthma. Our outcomes were LOS and total charges per hospital admission; hospitals were categorized as children's hospitals and nonchildren's hospitals. We adjusted for the following potential confounders: number of diagnoses, insurance information, patient age in years, race of patient, admission source, procedures, teaching status of hospital, and hospital location. Because of the right skew of the outcomes, our primary analyses consisted of robust median regression; to support our final models, we also performed sensitivity analyses. RESULTS: Of 252262 total inpatient encounters, 24322 met the inclusion criteria. There were 3408 encounters from 23 different freestanding children's hospitals and 20914 encounters from 1749 nonchildren's hospitals. Freestanding children's hospitals provided care to a higher risk population with more children transferred from other hospitals, a higher percentage of minorities, increased number of co-diagnoses, and a higher percentage on Medicaid. There was no statistically significant difference in LOS by hospital type. However, there was a significant difference in total costs, with the median cost of an admission at freestanding children's hospitals 1294 dollars more per hospitalization than at nonchildren's hospitals, after adjusting for confounders. CONCLUSION: We found no significant difference in median LOS among freestanding children's hospitals and nonchildren's hospitals, but freestanding children's hospitals had higher total charges per admission, even after adjusting for differences in population characteristics. Additional studies are needed to elucidate whether these increased costs result in better health outcomes or are simply attributable to other characteristics of children's hospitals, in which not all patients may benefit.

Pediatric eye injury-related hospitalizations in the United States.

OBJECTIVE: An estimated 2.4 million eye injuries occur in the United States each year, with nearly 35% of injuries among persons aged 17 years or less. Although previous research has identified some of the characteristics of pediatric eye injuries, many studies focused only on a specific patient population or type of eye injury or relied on self-reported data. In addition, little information has been reported on the total charges associated with treating pediatric eye injuries. Using a large national database, our aim was to examine hospitalizations for the treatment of pediatric eye injuries in the United States, including the demographic, medical care, and financial characteristics associated with major categories of eye injury. METHODS: Cross-sectional data were derived from the 2000 Kids' Inpatient Database of the Healthcare Cost and Utilization Project. Eye injury-related hospitalizations were identified by using International Classification of Disease, Ninth Revision, Clinical Modification codes. Discharges were selected if the eye injury was the principal or secondary diagnosis. Guidelines from the Centers for Disease Control and Prevention were used to group external-cause-of-injury codes into broader categories to allow meaningful comparison with previous studies. The reported charges for the treatment of eye injuries and the expected primary payer were determined. Cases were statistically weighted to produce national estimates of hospitalizations for pediatric eye injuries and to determine the characteristics of these injuries. RESULTS: Data were collected by the Kids' Inpatient Database for 3834 actual eye injury-related hospitalizations. These records represent an estimated 7527 eye injury-related hospitalizations among children aged 20 years or less in the United States during 2000. Inpatient charges for the treatment of these injuries were more than $88 million. The rate of hospitalization for pediatric eye injuries in the United States in 2000 was 8.9 per 100,000 persons aged 20 years or less. Young adults aged 18 to 20 years accounted for the highest percentage of hospitalizations (23.7%). Males accounted for 69.7% of hospitalizations. A majority of hospitalizations were for open wounds of the ocular adnexa. Motor vehicle crash was the most common cause of injury, followed by being struck by or against an object and being cut or pierced. CONCLUSIONS: These findings illustrate the considerable morbidity, financial burden, and proximal causes for pediatric eye injury-related hospitalizations. Our data support the need for eye injury prevention efforts that consider the age, gender, and developmental stage of children. Educating parents and children about the potential for eye injuries at home and during hazardous activities is an important public health goal. In addition, promoting the use of appropriate protective eyewear by children during activities with a high risk of ocular trauma will help prevent future eye injuries.

Hospitalizations of newborns with folate-sensitive birth defects before and after fortification of foods with folic acid.

CONTEXT: The prevalence of neural tube defects is reduced in populations of women who receive folic acid supplementation. Since 1998, grain products in the United States have been fortified with folic acid. Fortification may have additional benefits by reducing the national prevalence of newborn hospitalizations for other folate-sensitive birth defects. OBJECTIVE: Our purpose with this work was to compare rates of hospitalizations of newborns with folate-sensitive birth defects before and after implementation of fortification of grains. METHOD: National hospital discharge data from the Healthcare Cost and Utilization Project were used to compute rates of newborn hospitalizations for selected birth defects per 10,000 live births in the United States. Newborn hospitalization rates involving congenital anomalies recognizable at birth were analyzed for 5 years before fortification of grains and 5 years after fortification. Additional analyses compared changes in newborn hospitalization rates for birth defects by race/ethnicity, income, insurance status, and region of the country. RESULTS: Newborn hospitalization rates for spina bifida decreased 21% from 1993-1997 to 1998-2002. Newborn hospitalization rates also decreased for anencephaly (20%) and limb-reduction defects (4%). Decline in hospitalizations for spina bifida occurred more often among Hispanic newborns (33%) than among white (13%) or black (21%) newborns. Decline in limb-reduction defects was seen primarily among blacks (11%). Findings using hospitalization data were similar to recent reports using birth defect surveillance systems with the exception of findings for orofacial clefts and conotruncal heart defects. No reductions were noted in newborn hospitalizations for these anomalies. CONCLUSIONS: Results from this ecological study fail to demonstrate substantial declines in newborn hospitalizations beyond those anticipated from a reduction in neural tube defects. The society-wide impact of the fortification program on birth defects and other health conditions should continue to be monitored.
