Clinical correlates of small area variations in population-based admission rates for diabetes.
To verify and elucidate the results of a previous study that documented four-fold variations in small area admission rates for diabetes mellitus in Washington state, the authors examined the hospital records of a sample of diabetes discharges from hospitals in high-, medium-, and low-rate counties. Hospitals in high-rate counties were generally smaller than those in medium- and low-rate counties and admitted a greater proportion of patients with mild illness. Also, physicians in hospitals in high-rate counties tended to be less vigorous in the diagnosis and treatment of diabetes. Variations in admission rates were not explained by coding errors or by differences in selected sociodemographic characteristics of admitted patients. The authors conclude that small area variations in hospitalization rates for diabetes were related to clinical differences in admission criteria and may also reflect differences in the medical management of hospitalized patients.

Ambiguities in the selection of the principal diagnosis: impact on data quality, hospital statistics and DRGs.
A statewide stratified, random sample of diabetes-related hospital discharges for Medicare and Medicaid recipients was reviewed to assess principal diagnosis coding validity. After reabstracting, only 60 percent of the sample were found to be unequivocally correct. In another 23 percent, the correct principal diagnosis could not be determined with certainty. Furthermore, ten percent of the cases where diabetes mellitus was coded as another diagnosis were ambiguous as to whether diabetes actually was the principal diagnosis. The potential impacts of these ambiguities on measures of admission rates, average length of stay, and hospital payment are examined.

Diabetes mortality in persons under 45 years of age.
A detailed review of death certificates in Washington State for the years 1968-1979 was undertaken to analyze diabetes mortality for persons under 45 years of age. Diabetics in this age group had a mortality rate from medical causes eight times higher than that of the comparable general population. Almost one-third of the deaths were due to acute complications for which there is definitive medical therapy. Over the 12-year period there was no consistent decline in mortality rates or in deaths from acute complications, nor was there evidence of increased survivorship as reflected in the average age at death. Although residence in areas of sparse medical resources was not associated with high mortality rates, a significant proportion of deaths in all geographical areas occurred at home or before arrival at a hospital. Mortality rates and the proportion of deaths from acute, potentially preventable causes were higher in this study than in other recently published series, suggesting that early diabetes mortality may be a more serious problem than has been previously recognized. Diabetes mortality in this age group can be considered a "sentinel health event" and should call attention to potential problems in health care delivery.

Hospitalization of medicaid children: analysis of small area variations in admission rates.
Population-based hospitalization rates were computed and analyzed for AFDC children among 14 small area subdivisions of the State of Washington. Medical-surgical admission rates ranged from 65.3 to 161.7 per 1,000 person-years among the 14 areas. Surgical admission rates were significantly higher in urban areas; medical admission rates were significantly higher in rural areas. The majority of variance in overall rates was accounted for by admissions for four diagnostic categories: gastroenteritis (18-fold differences), lower respiratory infections (15-fold differences), upper respiratory infections (8-fold differences), and ear, nose, and throat (ENT) surgery (6-fold differences). Secondary analysis indicates that these differences in admission rates were not associated with: medical need or demographic factors, epidemic patterns of disease, physician supply, hospital bed supply or occupancy rates, or severity of disease or delay in seeking medical care as reflected by average length of stay. It is possible that the observed variations may reflect either differences in the propensity of local physicians to hospitalize or differences in the use or adequacy of community, ambulatory, and preventive care.

Rh hemolytic disease. Epidemiologic surveillance in the United States, 1968 to 1975.
Nationwide surveillance of Rh hemolytic disease of the newborn showed that associated infant mortality decreased from 941 deaths in 1968 to 269 deaths in 1975, or from 2.7 to 0.9 per 10,000 live births. The incidence of Rh hemolytic disease declined from 45 per 10,000 total births in 1970 to 21 per 10,000 in 1975. In 1970, an estimated 16,000 infants were affected, whereas in 1975, the number was 6,000. Several state-based Rh disease surveillance programs reported declining mortality and incidence and increasing use of Rh immune globulin. Rh immune globulin was administered to an estimated 80% of eligible Rh-negative women in 1974, eighty-one percent in 1975, and 82% in 1976. More concerted efforts are needed to determine the frequency of maternal sensitization and to identify and correct gaps in postpartum and postabortion use of Rh immune globulin.

Methodologic issues in pediatric outcomes research.
Clinicians, health services researchers, and third-party payers, among others, are justifiably interested in the outcomes of pediatric medical care and are, therefore, supportive of research in this area. Pediatric populations pose some unique methodologic challenges for health services researchers. To date, however, many of the approaches, models, and techniques used in pediatric outcomes research have been imported uncritically from experience with adult populations. As a result, some of the most interesting and salient aspects of pediatric outcomes research have yet to be fully developed. These include the following: 1) the problems posed by the dynamics of childhood development, 2) an emphasis on health supervision, 3) the need to see children within the context of a family system and to appreciate the interrelatedness of child health domains, 4) the measurement of the effects of interventions that span sectors, and 5) the paucity of available data sources. This article reviews these problematic areas and argues for a broad conceptual definition of pediatric health, a systems approach to assessing outcomes, and increased interdisciplinary collaboration.

Continuity and quality of care for children with diabetes who are covered by medicaid.
BACKGROUND: Poor and minority children with Type 1 diabetes mellitus are at increased risk of severe adverse outcomes as a result of their disease. However, little is known about the quality of care that these children receive and which factors are associated with better quality of care. OBJECTIVES: Our objectives were as follows: 1) to describe the utilization of services associated with quality of care for children with Type 1 diabetes mellitus who are covered by Medicaid and 2) to test the hypothesis that increased continuity of primary care is associated with better care for these children. DESIGN: Retrospective cohort study. METHODS: Washington State Medicaid claims data for 1997 were used to determine what proportion of children with diabetes had 1) an inpatient or outpatient diagnosis of diabetic ketoacidosis (DKA), 2) a glycosylated hemoglobin (HgA1c) level that had been checked, 3) a retinal examination, and 4) thyroid function studies. Continuity of care was quantified using a pre-established index. RESULTS: Two hundred fifty-two eligible patients were identified. During the observation year, 20% had an outpatient diagnosis of DKA, 6% were admitted with DKA, 43% visited an ophthalmologist, 54% had their HgA1c checked, and 21% had their thyroid function assessed. Children with high continuity of care were less likely to have DKA as an outpatient (0.30 [0.13-0.71]). Children with medium continuity of care and high continuity of care were less likely to be hospitalized for DKA (0.22 [0.05-0.87] and 0.14 [0.03-0.67], respectively). For preventive services utilization, high continuity of care was associated only with an increased likelihood of visiting an ophthalmologist (2.80 [1.08-3.88]). CONCLUSIONS: The quality of care for Medicaid children with diabetes can be substantially improved. Low continuity of primary care is an identifiable risk factor for DKA.

Epidemiologic approaches to the identification of problems in diabetes care.
We conducted two epidemiologic studies in Washington state to identify remediable problems in health care for persons with diabetes. In one study, mortality among persons with diabetes under the age of 45 was found to be 8 times higher than that in nondiabetic individuals of the same age. One-third of the deaths may have been preventable; problems in access to care may have contributed to premature mortality for some of these cases. The second investigation found that in counties with high hospital admission rates for diabetes, medical care may have been suboptimal. In these counties there was greater likelihood of hospitalization for mild metabolic problems, and less vigorous diagnostic and therapeutic management of hospitalized patients with similar case urgency. Population-based epidemiologic studies can identify health care problems and help focus interventions to improve diabetes care.

Reproductive and sexual health benefits in private health insurance plans in Washington State.
CONTEXT: Although unintended pregnancy and sexually transmitted diseases (STDs) are considerable problems in the United States, private health insurance plans are inconsistent in their coverage of reproductive and sexual health services needed to address these problems. METHODS: A survey administered to a market-representative sample of 12 health insurance carriers in Washington State assessed benefit coverage for gynecologic services, maternity services, contraceptive services, pregnancy termination, infertility services, reproductive cancer screening, STD services, HIV and AIDS services, and sterilization, as well as for the existence of confidentiality policies. "Core" services in each category were defined based on U.S. Preventive Services Task Force and other recommendations. RESULTS: Of the 91 top-selling plans on which data were collected, 8% were indemnity plans, 14% were point-of-service plans, 21% were preferred-provider organization plans and 57% were health maintenance organization (HMO)-type products; they had a combined enrollment of 1.4 million individuals. Coverage of core services varied widely by type of plan. While a high proportion of plans covered core gynecologic, maternity, reproductive cancer screening, STD and HIV and AIDS services, nearly half of plans did not cover any kind of contraceptive method. Approximately 13% of female enrollees did not have core coverage for gyneco!ogic services, 19% for matemity services, 75% for contraception, 37% for sterilization and 53% for pregnancy termination; 98% of women and men were not covered for infertility treatment. Most carriers did not have specific policies for maintaining privacy of sensitive health information. Overall, benefit coverage was lower for indemnity, preferred-provider organization and HMO plans in Washington State than has previously been seen nationally. CONCLUSIONS: A sizable proportion of women and men in Washington State who rely on private-sector health insurance lack comprehensive coverage for key reproductive and sexual health services.

Situational and financial barriers to prenatal care in a sample of low-income, inner-city women.
The relationship between the use of prenatal care and factors that may impede access to care was examined in a sample of low-income, inner-city women. Situational and financial barriers to care were not important correlates of utilization. In unadjusted analyses, only insurance status and employment status were associated with utilization. Of the sociodemographic characteristics studied, only parity was strongly associated with the use of prenatal care. When the apparent associations between utilization and insurance status and utilization and employment were analyzed controlling for parity, the estimated strength and statistical significance of these relationships diminished considerably. Multiparous women who were more likely than primiparous women to be underutilizers were also more likely to be on medical assistance and to be unemployed. These findings suggest that situational and financial barriers are not important correlates of utilization for low-income, adult women living in urban areas where there are accessible clinic facilities and public transportation. Efforts to identify and surmount other kinds of barriers may prove to be a more effective approach to prenatal outreach for women in these circumstances.

Outcomes of a diabetes education program.
This study is the first part of an evaluation of a model program of education on diabetes mellitus for diabetic outpatients, currently in progress in Washington State. The program consists of 16 hours of education, covering all aspects of self-care, with an emphasis on the prevention of unnecessary morbidity from poor control of the disorder or from infections. Eighty-eight percent of participants included in this study had not had formal diabetes education since receiving their diagnosis. The average duration of participants' diabetes was more than 7 years, and their average age was 55 years. Participants were evaluated just before and 3 months after the education program. During this interval, they made significant improvements in their knowledge of diabetes and their attitudes toward and skills in managing the disorder, as well as in their degree of satisfaction with control. Moreover, their random blood glucose and glycosylated hemoglobin (Hb Alc) levels were significantly lower at the 3-month followup. The authors suggest that outpatient education offers a significant improvement in diabetic control.

The impact of extended maternity services on prenatal care use among Medicaid women.
The goals of this study were to examine the use of maternity support services (MSS) and maternity case management (MCM) by Medicaid-eligible low-income pregnant women in Washington state, and to determine whether receipt of the services was associated with improved prenatal care use. We obtained data from linked birth certificates and Medicaid eligibility and claims files for women delivering between August 1989 and December 1991. Unconditional logistic regression was used to assess the programs' effects independent of other variables associated with prenatal care adequacy. The percentage of women receiving MSS and MCM was highest among women with demographic risks for adverse birth outcomes. Women receiving prenatal care from health departments or community clinics were more likely to receive MSS and MCM than those seen by private physicians or midwives. After adjustment for multiple confounding factors, we found that recipients of MSS, but not MCM, were significantly less likely than other women to receive an inadequate number of prenatal visits. Our findings suggest that public policies that pay for support services to low-income pregnant women can improve the use of prenatal care.

Adolescent pregnancy and sexual risk-taking among sexually abused girls.
Data on 3,128 girls in grades eight, 10 and 12 who participated in the 1992 Washington State Survey of Adolescent Health Behaviors were used to analyze the association of a self-reported history of sexual abuse with teenage pregnancy and with sexual behavior that increases the risk of adolescent pregnancy. In analyses adjusting for grade level, respondents who had been sexually abused were 3.1 times as likely as those who had not been abused to say they had ever been pregnant; in multivariate analyses, respondents who had experienced abuse were 2.3 times as likely as others to have had intercourse but were not more likely than other sexually active respondents to have been pregnant. However, those with a history of sexual abuse were more likely to report having had intercourse by age 15 (odds ratio, 2.1), not using birth control at last intercourse (2.0) and having had more than one sexual partner (1.4). Thus, an association between sexual abuse and teenage pregnancy appears to be the result of high-risk behavior exhibited by adolescent girls who have been abused.
