The rheumatoid hand: a predictable disease with unpredictable surgical practice patterns.

OBJECTIVES: To evaluate variation in fusion, arthroplasty, and tenosynovectomy rates among rheumatoid arthritis (RA) patients across states; to evaluate associations between surgery rates and the density of hand surgeons; and to evaluate differences in treatment by sex of the patient. METHODS: Data were obtained from the 1996 and 1997 Healthcare Cost and Utilization Project database. The procedure codes for fusion, arthroplasty, and tenosynovectomy were matched to patients with the diagnostic code of RA, which provided the total number of procedures performed in each state. The smoothed estimates of the RA population for each state were derived from age/sex strata in the 1995 US census using age/sex-adjusted RA prevalence data from the Third National Health and Nutrition Examination Survey. The number of hand surgeons was from the 1996 American Society for Surgery of the Hand. RESULTS: Procedure rates across states varied from 9-fold to 12-fold for all 3 procedures. The rates of the reconstructive procedures-fusion and arthroplasty-were highly correlated in each state, but these 2 procedures were only moderately correlated with tenosynovectomy. Surgeon density and procedure rates were minimally correlated. Procedure rates differed by patient sex, with significantly more arthroplasty and fusion procedures performed in women. More tenosynovectomy procedures were performed in men, and they were also performed at a younger age in men. CONCLUSIONS: Significant large area variations are present in the surgical management of the rheumatoid hand, but the correlations between reconstructive and early intervention procedures are modest. These rate differences are not explained by the number of hand surgeons, disease prevalence, or demographic composition of the states. However, men are more likely to receive more aggressive early surgical interventions, and women are more likely to receive end-stage reconstructive surgery.

Hospitalizations for coronary artery disease among patients with systemic lupus erythematosus.

OBJECTIVE: Although patients with systemic lupus erythematosus (SLE) have an increased risk of coronary artery disease (CAD) compared with persons without SLE, the burden of CAD among SLE patients is unknown. This study was undertaken to estimate this burden. METHODS: We used the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project to estimate the number of hospitalizations for CAD among patients with SLE in the US in 1998. CAD diagnoses included acute myocardial infarction (MI), unstable angina, cardiac catheterization, percutaneous transluminal coronary angioplasty, or coronary artery bypass grafting as the primary reason for hospitalization. We compared these estimates with the frequency of hospitalization for other reasons. RESULTS: There were an estimated 98,217 hospitalizations among patients with SLE in 1998. Of these, 11,947 (12%) were among men, 43,674 (44%) were among women <50 years of age, and 42,596 (43%) were among women > or =50 years of age. There were 4,951 hospitalizations for CAD, with 1,763 of these for acute MI. In women <50 years old, there were an estimated 311 hospitalizations for MI. Hospitalizations for CAD were less common than hospitalizations for SLE itself or for infections, and in young women, were less common than hospitalizations for complications of chronic renal failure. CONCLUSION: CAD is an important comorbid condition in patients with SLE, but is not as common a reason for hospitalization as SLE itself, infections, and, in some patient subgroups, chronic renal failure.

Direct medical costs of polymyalgia rheumatica.

OBJECTIVE: To describe the patterns of care and direct medical costs of polymyalgia rheumatica (PMR) to test the hypothesis that the direct medical costs incurred by patients with PMR are higher than costs incurred by age- and sex-matched population-based controls from the same community. METHODS: The study population comprised 193 Olmsted County, Minnesota residents who were first diagnosed with PMR between January 1, 1987 and December 31, 1999. Inclusion criteria were as follows: age > or = 50 years; bilateral aching and morning stiffness (lasting > or = 30 minutes) persisting for at least 1 month and involving the neck, shoulders, or hip girdle regions; and an erythrocyte sedimentation rate (ESR) > or = 40 mm/hour. In patients who fulfilled the first 2 criteria, but had a normal ESR, a rapid response to low-dose corticosteroids served as the third criterion. A total of 695 age- and sex-matched subjects without PMR served as control subjects. Billing data from the Olmsted County Healthcare Expenditure and Utilization Database (OCHEUD) were used to provide estimates of nationally representative unit costs in the year 2002 inflation-adjusted dollars. All subjects were followed using the OCHEUD records until December 31, 2002 to assess the total direct medical costs. Generalized quantile regression modeling was used to estimate the effect of PMR on direct medical costs, after adjusting for age, sex, Charlson comorbidity score, number of hospital days, and number of radiographs. RESULTS: During the first year following diagnosis, subjects with PMR used a substantially higher number of outpatient services and laboratory tests compared with controls, but during the subsequent 4 years, there were no differences between the 2 groups. In age- and sex-adjusted analysis, PMR was associated with a significant incremental cost of 2,233 dollars at the 10th percentile of costs and 27,712 dollars at the 90th percentile of costs. However, further adjustments for comorbidities, number of hospital days, radiographs, and imaging eliminated the incremental cost difference between the subjects with PMR and control subjects. PMR subjects were significantly more likely to have a history of myocardial infarction (odds ratio [OR] 1.78, 95% confidence interval [95% CI] 1.13, 2.82), peripheral vascular diseases (OR 2.21, 95% CI 1.37, 3.60), and cerebrovascular diseases (OR 1.60, 95% CI 1.08, 2.39) compared with the controls. CONCLUSION: Incremental direct medical costs associated with the management of PMR can be substantial, especially early in the disease course. These incremental costs appear to originate mainly from comorbid cardiovascular conditions that were shown to be more prevalent among subjects with PMR.

Obstetric hospitalizations in the United States for women with systemic lupus erythematosus and rheumatoid arthritis.

OBJECTIVE: To estimate the national occurrence of pregnancies in women with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) and to compare pregnancy outcomes in these patients with those in women with pregestational diabetes mellitus (DM) and with the general obstetric population. METHODS: We studied the 2002 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project to estimate the number of obstetric hospitalizations, deliveries, and cesarean deliveries in women with SLE, RA, pregestational DM, and the general obstetric population. Pregnancy outcomes included length of hospital stay, hypertensive disorders including preeclampsia, premature rupture of membranes, and intrauterine growth restriction. RESULTS: Of an estimated 4.04 million deliveries, 3,264 occurred in women with SLE, 1,425 in women with RA, and 13,574 in women with pregestational DM. Women with SLE, RA, and pregestational DM had significantly increased rates of hypertensive disorders compared with the general obstetric population (23.2%, 11.1%, 27.4%, and 7.8%, respectively), longer hospital stays, and significantly higher risk of cesarean delivery. Although women with SLE, RA, and pregestational DM were significantly older than women in the general obstetric population, disparities in the risk of adverse outcomes of pregnancy remained statistically significant after adjustment for maternal age. CONCLUSION: To our knowledge, this is the first study to examine national data on pregnancy outcomes in women with common rheumatic diseases. As with underlying pregestational DM, women with SLE and RA appear to have a higher age-adjusted risk of adverse outcomes of pregnancy and longer hospital stays than do pregnant women in the general population, and careful antenatal monitoring should be performed.

National rates of birth defects among hospitalized newborns.

BACKGROUND: The Healthcare Cost and Utilization Project (HCUP) family of hospital discharge databases offer an unprecedented opportunity to generate national estimates of newborn infants with birth defects. This report estimates national hospital admissions for newborn infants diagnosed with birth defects computed from HCUP and compares them to pooled prevalence figures computed from state birth defect surveillance systems. METHODS: HCUP-derived rates of 36 birth defects from 1997 through 2001 were compared to rates derived from pooled data reported by 26 state-based surveillance systems stratified by inclusion of elective terminations in case definitions. Rate ratios (RRs) were calculated for each birth defect by dividing the rate derived from HCUP by the rate derived from the relevant surveillance systems. RESULTS: HCUP newborn hospitalization rates for birth defects closely approximate pooled birth defect rates for surveillance systems that do not include elective terminations. HCUP rates were not significantly different for 35 of 36 defects. Overall, 20 HCUP rates were within 10% of state rates, 11 more were within 20% of state rates, and only 1 differed by more than 50%. HCUP rates compared most closely to state rates for cardiovascular (VSD RR = 0.98, ASD = 0.96, pulmonary valve atresia and stenosis = 0.92), orofacial (cleft palate RR = 1.10, cleft lip = 1.06), and genitourinary defects (obstructive genitourinary RR = 1.01, bladder exstrophy = 0.97). HCUP rates compared less favorably to rates derived from surveillance systems that included elective terminations. CONCLUSIONS: HCUP data approximate state-based surveillance system data for defects that are easily recognized in the newborn period and infrequently a cause for elective termination. HCUP data can be used to examine the impact of public health efforts on the number of infants born with birth defects as well as the cost and consequences of variations in the hospital management of birth defects.

Morbidity and mortality of colorectal carcinoma surgery differs by insurance status.

BACKGROUND: Uninsured and underinsured patients are reported to be at an increased risk for impaired access to healthcare, delayed medical treatment, and the receipt of substandard care. These differences in care may result in disparities in surgical outcomes among patients with different types of insurance. In the current study, the authors examined associations between the insurance provider and short-term surgical outcomes after surgery for colorectal carcinoma and evaluated the extent to which two risk factors (comorbid disease and admission type) might explain any observed association. METHODS: The authors conducted a nationally representative retrospective cohort study of 13,415 adults ages 40-64 years who were admitted for surgery for colorectal carcinoma to hospitals that participated in the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project National Inpatient Sample, releases 6 and 7, in 1997 and 1998. Multivariate logistic regression models were developed to describe the correlations between insurance status and the risks of a postoperative complication or postoperative death after adjustment for socioeconomic factors, comorbid conditions, and admission type. RESULTS: Uninsured and Medicaid patients were found to have more emergent admissions and more comorbid disease compared with patients with private health insurance. Patients without private health insurance had higher rates of postoperative complications and in-hospital death compared with those patients with private insurance. After adjusting for patient and hospital characteristics, patients with Medicaid were found to be 22% more likely to develop a complication during their hospital admission (odds ratio [OR] of 1.22; 95% confidence interval [95%CI], 1.06-1.40) and 57% more likely to die postoperatively (OR of 1.57; 95% CI, 1.01-2.42) compared with patients with private insurance. CONCLUSIONS: The current study findings suggest that the uninsured and Medicaid populations are at greater risk of developing postoperative complications and dying than the privately insured population due only in part to preexisting medical comorbidities and emergent admission type.

Trends in health care resource use for hepatitis C virus infection in the United States.

Chronic hepatitis C virus (HCV) infection affects approximately 3 million people in the United States and places tremendous demands on the health care system. As many observers have predicted, the disease burden continues to grow as the infected population ages. In this study, we analyzed inpatient data from the Healthcare Cost and Utilization Project, outpatient data from the National Ambulatory Medical Care Survey, and drug data from the Verispan Source Prescription Audit. We examined recent growth in the use of health care resources among HCV patients by age group and found average annual increases of 25% to 30% for hospitalizations, charges, hospital days, and physician visits. Corresponding time-trend coefficients were positive (P < .001). From 1994 to 2001, the HCV burden increased among patients aged 40 to 60 years, reflecting the natural history of disease progression. In sensitivity analysis, HCV outcome growth rates remained significant, unless more than 3 out of 4 cases were initially underreported. Also, patients co-infected with HIV and HCV in 2001 constituted 7.5 times as many hospitalizations and incurred 2.9 times the charges in 1994, relative to all HIV hospitalizations and charges. Our findings highlight the urgency concerning HCV outcomes. In conclusion, as patients continue to age and disease burden progresses, suboptimal decisions regarding HCV treatments will bring increasing opportunity costs for the health care system and society.

Variation in hospitalizations and hospital length of stay in children with vaso-occlusive crises in sickle cell disease.

OBJECTIVE: As a measure of morbidity of vaso-occlusive crises (VOC) in sickle cell disease, we used a national hospital discharge database, the Kids' Inpatient Database (KID), to determine the number of hospitalizations and hospital length of stay (LOS) by age. PROCEDURE: Nationally weighted hospital discharges for VOC in children with sickle cell disease were analyzed using data from 2,500 hospitals in the Healthcare Cost and Utilization Project (HCUP) KID. Number of discharges and hospital LOS by age group were analyzed. Multiple linear regression was performed to analyze the effect of age on hospital LOS. RESULTS: There were 20,271 hospital discharges for children with sickle cell disease and VOC. Mean age (SD) at time of admission was 10.6 (5.38) years with 49% being males. The overall average LOS was 4.4 days. There were differences in the number of hospital discharges by age group (P < 0.001). In addition, there was a difference in LOS by age group (P < 0.0001). After controlling for potential confounders, older age was associated with a longer LOS (P < 0.0001). CONCLUSIONS: Older children with sickle cell disease and VOC have increased hospitalizations and longer LOS. This age effect should be considered when measuring the effect of an intervention on hospital utilization in these children.

The near absence of osteoporosis treatment in older men with fractures.

The burden of osteoporotic fractures in older men is significant. The objectives of our study were to: (1) characterize older men with fractures associated with osteoporosis, (2) determine if medication treatment rates for osteoporosis are improving and (3) identify patient, healthcare benefit and utilization, and clinician characteristics that are significantly associated with treatment. This retrospective cohort study assessed 1,171 men aged 65 or older with any new fracture associated with osteoporosis between 1 January 1998 and 30 June 2001 in a non-profit health maintenance organization in the United States. Multiple logistic regression was used to evaluate pre-fracture factors for their association with osteoporosis treatment in the 6-month post-fracture period. The main outcome measure was pharmacologic treatment for osteoporosis in the 6 months after the index fracture. Subjects' average age was 76.7 years; 3.3% had a diagnosis of osteoporosis and 15.2% a diagnosis or medication associated with secondary osteoporosis. Only 7.1% of the study population and 16.0% of those with a hip or vertebral fracture received a medication for osteoporosis following the index fracture, and treatment rates did not improve over time. In the multivariate model, factors significantly associated with drug treatment were a higher value on the Charlson Comorbidity Index (odds ratio 1.26, 95% confidence interval 1.05-1.51), having an osteoporosis diagnosis (odds ratio 8.11, 95% confidence interval 3.08-21.3), chronic glucocorticoid use (odds ratio 5.37, 95% confidence interval 2.37-12.2) and a vertebral fracture (odds ratio 16.6, 95% confidence interval 7.8-31.4). Bone mineral density measurement was rare (n =13, 1.1%). Our findings suggest that there is under-ascertainment and under-treatment of osteoporosis and modifiable secondary causes in older men with fractures. Information systems merging diagnostic and treatment information can help delineate gaps in patient management. Interventions showing promise in other conditions should be evaluated to improve care for osteoporosis.

Do patient or hospital demographics predict cholecystectomy outcomes? A nationwide study of 93,578 patients.

BACKGROUND: The purpose of this study was to examine the influence of patient and hospital demographics on cholecystectomy outcomes. METHODS: Year 2000 data from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database was obtained for all patients undergoing inpatient cholecystectomy at 994 nationwide hospitals. Differences (p < 0.05) were determined using standard statistical methods. RESULTS: Of 93,578 cholecystectomies performed, 73.4% were performed laparoscopically. Length of hospital stay (LOS), charges, morbidity, and mortality were significantly less for laparoscopic cholecystectomy (LC). Increasing patient age was associated with increased LOS, charges, morbidity, mortality, and a decreased LC rate. Charges, LOS, morbidity, and mortality were highest for males with a lower LC rate than for females Mortality and LOS were higher, whereas morbidity was lower for African Americans than for whites. Hispanics had the shortest LOS, as well as the lowest morbidity and mortality rates. Laparoscopic cholecystectomy was performed more commonly for Hispanics than for whites or African Americans, with lower charges for whites. Medicare-insured patients incurred longer LOS as well as higher charges, morbidity, and mortality than Medicaid, private, and self-pay patients, and were the least likely to undergo LC. As median income decreases, LOS increases, and morbidity decreases with no mortality effect. Teaching hospitals had a longer LOS, higher charges, and mortality, and a lower LC rate, with no difference in morbidity, than nonteaching centers. As hospital size (number of beds) increased, LOS, and charges increased, with no difference in morbidity. Large hospitals had the highest mortality rates and the lowest incidence of LC. Urban hospitals had higher LOS and charges with a lower LC rate than rural hospitals. After control was used for all other covariates, increased age was a predictor of increased morbidity. Female gender, LC, and intraoperative cholangiogram all predicted decreased morbidity. Increased age, complications, and emergency surgery predicted increased mortality, with laparoscopy and intraoperative cholangiogram having protective effects. Patient income, insurance status, and race did not play a role in morbidity or mortality. Academic or teaching status of the hospital also did not influence patient outcomes. CONCLUSIONS: Patient and hospital demographics do affect the outcomes of patients undergoing inpatient cholecystectomy. Although male gender, African American race, Medicare-insured status, and large, urban hospitals are associated with less favorable cholecystectomy outcomes, only increased age predicts increased morbidity, whereas female gender, laparoscopy, and cholangiogram are protective. Increased age, complications, and emergency surgery predict mortality, with laparoscopy and intraoperative cholangiogram having protective effects.

Long-term morbidity and mortality among a sample of cocaine-dependent black and white veterans.

Racial minorities generally exhibit worse health status than do whites. To assess the presence of similar phenomena among long-term cocaine-using veterans, this study examined racial variations in mortality and health status among cocaine-dependent men who were originally recruited at their admissions to cocaine treatment in 1988-1989 and were interviewed approximately 12 years later in 2002-2003. Mortality was higher among whites (15%) than blacks (6%), particularly due to drug overdose. Controlling for socioeconomic factors, cocaine severity, and depression, the racial difference was still significant in the survival analysis. Racial differences were examined in the health status of those interviewed in the 12-year follow-up study (178 blacks and 65 whites), after confirmation of their comparable socioeconomic backgrounds and levels of healthcare access and utilization. Contrary to expectations, few racial differences were found on most health indicators, although the level of cocaine use was higher among blacks. Furthermore, fewer blacks reported having hepatitis or sexually transmitted diseases than did whites. The study results suggest that black cocaine-dependent veterans do not have worse health status when compared with white veterans on most health indicators.

Gender inequalities of health in the Third World.

This paper examines gender inequalities of health in Third World Countries. Health hazards are present at every stage of a woman's life cycle. Health problems which pose the greatest hardship to women in these countries include: reproductive health problems, excess female mortality in childhood, violence against girls and women, occupational and environmental hazards, and cervical and breast cancer. Many of these lead to maternal mortality which was the most focussed upon indicator of women's health in the literature. Gender inequalities of health originate in the traditional society where definitions of health status and traditional medical practices all reflect the subordinate social status of women. Gender inequalities in health are manifested in traditional medical practices which attribute women's illnesses to behavioral lapses by women; differential access to and utilization of modern healthcare services by women and girls, including maternal care, general healthcare, family planning and safe abortion services. Reasons for gender inequalities in health include--emphasis on women's childbearing roles resulting in early and excessive childbearing; sex preference manifested in discrimination against female children in health and general care; women's workloads which not only expose them to health hazards but also make it difficult for them to take time off for healthcare; lack of autonomy by women leading to lack of decision-making power and access to independent income; early marriage which exposes women to the complications of early and excessive childbearing. Gender inequality in health is one of the social dimensions in which gender inequality is manifested in Third World societies. Strategies to eradicate gender inequalities in health must therefore involve efforts to improve the status of women.

Characteristics of motorcycle-related hospitalizations: comparing states with different helmet laws.

This study compares U.S. motorcycle-related hospitalizations across states with differing helmet laws. Cross-sectional analyses of hospital discharge data from 33 states participating in the Healthcare Cost and Utilization Project in 2001 were conducted. Results revealed that motorcyclists hospitalized from states without universal helmet laws are more likely to die during the hospitalization, sustain severe traumatic brain injury, be discharged to long-term care facilities, and lack private health insurance. This study further illustrates and substantiates the increased burden of hospitalization and long-term care seen in states that lack universal motorcycle helmet use laws.

Motorcycle-related hospitalizations in the United States, 2001.

OBJECTIVES: To estimate the prevalence of motorcycle-related hospitalization in the United States in 2001 and to describe the demographic, clinical, hospital, and financial characteristics associated with these injuries. METHODS: Cross-sectional analysis of the 2001 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project was conducted in 2003. RESULTS: There were an estimated 30,505 (confidence interval=26,566-34,445) motorcycle-related hospital discharges in 2001. Approximately 62% of cases were aged > or =30 years, and males accounted for 89% of cases. The most common principal diagnoses were fractures of the lower limb (29.4%), fractures of the upper limb (13.1%), and intracranial injuries (12.3%). The mean length of stay was 5 days, the median hospital charge was $15,404, and the total estimated hospital charges were >$841 million. The majority of patients (56.5%) were admitted to large urban teaching hospitals, and these hospitals accounted for nearly 70% of all hospital charges. Approximately 26% of cases were self-pay or listed public insurance as the expected payer. CONCLUSIONS: These findings shed light on the substantial morbidity and financial impact of motorcycle-related injuries. Renewed and strengthened prevention efforts are warranted.

Community health workers as interventionists in the prevention and control of heart disease and stroke.

A considerable body of research indicates that community health workers (CHWs) are effective in improving chronic disease care and health outcomes. Much of the focus of cardiovascular research involving CHWs has been on hypertension because of its high prevalence and because it is a major risk factor for cardiovascular, cerebrovascular, and renal diseases. Adding CHWs to the patient-provider team has a beneficial effect on the quality of care for populations most in need. CHWs have contributed to significant improvements in community members' access to and continuity of care and adherence to treatment for the control of hypertension. CHWs assume multiple roles, including patient and community education, patient counseling, monitoring patient health status, linking people with health and human services, and enhancing provider patient communication and adherence to care. Current recommendations for CHWs to be interventionists on healthcare teams and in community-based research increase opportunities for CHWs to play an important role in eliminating disparities in heart disease and stroke. Adequate translation of research into clinical practice remains a major challenge, however. Addressing this issue, which has national implications, will require sustainable funding; appropriate reimbursement; enhanced efforts to incorporate CHWs into healthcare teams; better utilization of their skills; improved CHW supervision, training, and career development; policy changes; and ongoing evaluation, including a reporting of costs.

Economic burden of endometriosis.

OBJECTIVE: To comprehensively review and evaluate the direct costs of endometriosis. DESIGN AND SETTING: We systematically reviewed studies published since 1990, and conducted an analysis of publicly available national databases (Healthcare Cost and Utilization Project and National Ambulatory Medical Care Survey/National Hospital Ambulatory Medical Care Survey) in the United States. We assessed: [1] the overall economic impact of endometriosis; [2] the direct costs associated with specific treatments; and [3] the indirect costs of endometriosis associated with reduced work productivity. RESULTS: Of 13 published studies meeting inclusion criteria, 11 (85%) addressed direct costs, a few studies addressed outpatient costs or indirect costs, and no study quantified the economic impact among adolescents. Direct endometriosis-related costs were considerable and appeared driven by hospitalizations. Our database analysis found: [1] as endometriosis-related hospital length of stay steadily declined from 1993 to 2002, per-patient cost increased 61%; [2] adolescents (aged 10-17 years) had endometriosis-related hospitalizations; [3] approximately 50% of >600,000 endometriosis-related ambulatory patient visits involved specialist care; and [4] females 23 years old or younger constituted >20% of endometriosis-related outpatient visits. CONCLUSIONS: Health economic information for endometriosis is scarce, limiting our understanding of its overall economic impact. Nevertheless, the literature and other available data suggest that endometriosis places a considerable burden on patients and society.

Community health worker training and certification programs in the United States: findings from a national survey.

OBJECTIVE: To analyze trends and various approaches to professional development in selected community health worker (CHW) training and certification programs in the United States. We examined the expected outcomes and goals of different training and certification programs related to individual CHWs as well as the community they serve. METHOD: A national survey of CHW training and certification programs. Data collection was performed through personal interviews, phone interviews and focus groups. Data sources included public health officials, healthcare associations, CHW networks, community colleges, and service providers. Initial screening interviews resulted in in-depth interviews with participants in 19 states. We applied human capital theory concepts to the analysis of the rich qualitative data collected in each state. RESULTS: CHW programs in the U.S. seem to have been initiated mainly due to lack of access to healthcare services in culturally, economically, and geographically isolated communities. Three trends in CHW workforce development were identified from the results of the national survey: (1) schooling at the community college level - provides career advancement opportunities; (2) on-the-job training - improves standards of care, CHW income, and retention; and (3) certification at the state level - recognizes the work of CHWs, and facilitates Medicaid reimbursement for CHW services. CONCLUSION: Study findings present opportunities for CHW knowledge and skill improvement approaches that can be targeted at specific individual career, service agency, or community level goals. Trained and/or certified community health workers are a potential new and skilled healthcare workforce that could help improve healthcare access and utilization among underserved populations in the United States.

Importance of organ dysfunction in determining hospital outcomes in children.

OBJECTIVES: To use measures of organ dysfunction derived from administrative data to assess clinical and economic outcomes in hospitalized children. STUDY DESIGN: We used the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic and procedure codes to evaluate organ dysfunction in all patients, excluding neonates, in the Healthcare Cost and Utilization Project Kids' Inpatient Database (KID). We adapted consensus clinical definitions to characterize organ dysfunction in terms of degree of impairment, type of organ system involvement, and number of dysfunctional organ systems. Univariate and multivariable models were constructed to determine the impact of organ dysfunction on in-hospital mortality and resource use. RESULTS: Patients with organ dysfunction (n=51,386) were younger and more often male than those without organ dysfunction, and they had significantly higher in-hospital mortality and resource use. Organ dysfunction, assessed in terms of degree, type, and number of dysfunctional organ systems, was consistently associated with all hospital outcomes. In multivariable models, types of organ system failures were most predictive of in-hospital mortality, whereas degree of organ system involvement allowed for a better assessment of resource use. CONCLUSIONS: Administrative data can be used to characterize multiple dimensions of organ dysfunction in children. Hospitalizations involving organ dysfunction are associated with significant clinical and economic consequences.
