Development and Evaluation of a Novel Patient Information System

A comprehensive patient information datafile of 320 topics has been developed, subserving the domains of medicine, surgery, gynaecology and paediatrics. The system was designed as loose-leaf sheets capable of being photocopied, as well as a computer-based datafile. In a four-practice study, 73% of consecutive general practice attenders could be issued with the relevant disorder or procedure information sheet. With a questionnaire return rate of 79%, 886 patients rated the three criteria of readability, understandability and usefulness of their leaflets as very or quite easy and very or quite useful in more than 94% of instances. This system could be a valuable adjunct to patient education in both general and hospital practice settings.

Transdisciplinary translational science and the case of preterm birth

Medical researchers have called for new forms of translational science that can solve complex medical problems. Mainstream science has made complementary calls for heterogeneous teams of collaborators who conduct transdisciplinary research so as to solve complex social problems. Is transdisciplinary translational science what the medical community needs? What challenges must the medical community overcome to successfully implement this new form of translational science? This article makes several contributions. First, it clarifies the concept of transdisciplinary research and distinguishes it from other forms of collaboration. Second, it presents an example of a complex medical problem and a concrete effort to solve it through transdisciplinary collaboration: for example, the problem of preterm birth and the March of Dimes effort to form a transdisciplinary research center that synthesizes knowledge on it. The presentation of this example grounds discussion on new medical research models and reveals potential means by which they can be judged and evaluated. Third, this article identifies the challenges to forming transdisciplines and the practices that overcome them. Departments, universities and disciplines tend to form intellectual silos and adopt reductionist approaches. Forming a more integrated (or 'constructionist'), problem-based science reflective of transdisciplinary research requires the adoption of novel practices to overcome these obstacles.

State welfare reform policies and maternal and child health services: a national study

OBJECTIVES

Welfare reform (Personal Responsibility and Work Opportunity Reconciliation Act of 1996) resulted in dramatic policy changes, including health-related requirements and the administrative separation of cash assistance from Medicaid. We were interested in determining if changes in welfare and health policies had had an impact on state MCH services and programs.

METHODS

We conducted a survey in fall 1999 of state MCH Title V directors. Trained interviewers administered the telephone survey over a 3-month period. MCH directors from all 50 states, Washington, DC, and Puerto Rico participated (n = 52; response rate = 100%).

RESULTS

Among the most noteworthy findings is that similar proportions of respondents reported that welfare policy changes had either helped (46%) or hindered (42%) the agency's work, with most of the positive impact attributed to increased funding. MCH data linkages with welfare and other social programs were low. Despite welfare reform's emphasis on work, limited services and exemptions were available for mothers with CSHCN. Almost no efforts have been undertaken to specifically address the needs of substance abusers in the context of new welfare policies.

CONCLUSIONS

Few MCH agencies have developed programs to address the special needs of women receiving TANF who either have health problems themselves or have children with health problems. Recommendations including increased MCH and family planning funding and improved coordination between TANF and MCH to facilitate linkages and services are put forth in light of reauthorization of PRWORA.

State income inequality, household income, and maternal mental and physical health: cross sectional national survey

OBJECTIVE

To examine the association of state income inequality and individual household income with the mental and physical health of women with young children.

DESIGN

Cross sectional study. Individual level data (outcomes, income, and other sociodemographic covariates) from a 1991 follow up survey of a birth cohort established in 1988. State level income inequality calculated from the income distribution of each state from 1990 US census.

SETTING

United States, 1991.

PARTICIPANTS

Nationally representative stratified random sample of 8060 women who gave birth in 1988 and were successfully contacted (89%) in 1991.

MAIN OUTCOME MEASURES

Depressive symptoms (Center for Epidemiologic Studies depression score >15) and self rated health

RESULTS

19% of women reported depressive symptoms, and 7.5% reported fair or poor health. Compared with women in the highest fifth of distribution of household income, women in the lowest fifth were more likely to report depressive symptoms (33% v 9%, P<0.001) and fair or poor health (15% v 2%, P<0. 001). Compared with low income women in states with low income inequality, low income women in states with high income inequality had a higher risk of depressive symptoms (odds ratio 1.6, 95% confidence interval 1.0 to 2.6) and fair or poor health (1.8, 0.9 to 3.5).

CONCLUSIONS

High income inequality confers an increased risk of poor mental and physical health, particularly among the poorest women. Both income inequality and household income are important for health in this population.

State welfare reform policies and declines in health insurance

OBJECTIVES

This study sought to determine whether there is a relationship between state policies on Temporary Assistance to Needy Families (TANF), declines in both TANF and Medicaid caseloads, and the rise in the number of uninsured.

METHODS

Extant data sources of state TANF policies, TANF and Medicaid participation, and uninsurance rates were analyzed, with the state as the unit of analysis. The independent variables included state TANF policies that directly address receipt of benefits or relate to health; dependent variables included changes in state TANF enrollment, Medicaid enrollment, and health insurance status since the enactment of the law.

RESULTS

In the bivariate analysis, declines in Medicaid were associated with sanction for work noncompliance, lack of a child care guarantee, and strategies to deter TANF enrollment; this last factor was also associated with increased uninsurance. In the multivariate analysis, lack of a child care guarantee and deterrent strategies predicted TANF declines; deterrent strategies predicted Medicaid decline and uninsurance increases.

CONCLUSIONS

This analysis suggests that policies deterring TANF enrollment may contribute to declines in Medicaid and increased uninsurance. To maintain health insurance for the poor, policymakers should consider revising policies that deter TANF enrollment.

The impact of managed care insurance on use of lower-mortality hospitals by children undergoing cardiac surgery in California

CONTEXT

Managed care plans aggressively seek to contain costs, but few data are available regarding their impact on access to high quality care for their members.

OBJECTIVE

To assess the impact of managed care health insurance on use of lower-mortality hospitals for children undergoing heart surgery in California.

DESIGN

Retrospective cohort study using state-mandated hospital discharge datasets.

SETTING

Pediatric cardiovascular surgical centers in California.

PATIENTS

Five thousand seventy-one children admitted for open cardiac surgical procedures during 1992-1994.

RESULTS

Hospitals were divided into lower- and higher-mortality groups according to adjusted surgical mortality. Using multivariate logistic regression analysis to control for medical, socioeconomic, demographic, and distance factors, children with managed care insurance were less likely to be admitted to a lower-mortality hospital for surgery relative to children with indemnity insurance (odds ratio:.53; 95% confidence interval:.45,.63). Similar findings resulted when the analysis was stratified by race/ethnicity. In addition, length of stay, a correlate of health care costs, was no longer for children admitted to lower-mortality centers than for those at higher-mortality centers (adjusted difference:.54 days shorter at lower-mortality centers; 95% confidence interval: -1.50,. 41).

CONCLUSIONS

During this study, children with managed care insurance had significantly reduced use of lower-mortality hospitals for pediatric heart surgery in California compared with children with indemnity insurance. Further study is necessary to determine the mechanisms of this apparent insurance-specific inequity.

Implementation of Fetal and Infant Mortality Review (FIMR): experience from the national Healthy Start program

OBJECTIVES

The implementation of the Fetal and Infant Mortality Review (FIMR) process was examined as part of the evaluation of the national Healthy Start program, a federal program designed to reduce infant mortality in several communities. The implementation of the FIMR process over the 5-year funding period is described in terms of productivity, barriers and facilitators to implementation, and project expenditures.

METHODS

Data were derived from grant continuation applications and personal interviews with program staff to produce a qualitative description.

RESULTS

As of the summer of 1996, 14 of the 15 Healthy Start sites in the national evaluation had successfully implemented the FIMR process. Most sites had developed a two-tiered review process for examination of case data in which a review by health and social services professionals was followed by community review. In the period 1993 to 1995, the percentage of fetal and infant deaths reviewed had a median of 34% with a range of 4-79% across the sites at a cost of $600 to $3400 per death reviewed. Recommendations were variably implemented.

CONCLUSIONS

The FIMR process provides an important opportunity to contribute to the knowledge base regarding infant mortality in these communities. The process, however, has important logistical requirements and may require substantial financial resources that may affect implementation of confidential inquiries into infant mortality and other health problems.

The scope of unmet maternal health needs in pediatric settings

OBJECTIVE

Previous work has focused attention on the prevalence of specific maternal health problems known to affect children, such as smoking or depression. However, the cumulative health burden experienced by mothers and the potential for a practical pediatric health services response have not been examined. The aims of this study were to characterize: 1) the prevalence and cumulative burden of maternal health behaviors and conditions, 2) maternal access to a source of comprehensive adult primary care, and 3) maternal perceptions of a pediatric role in screening and referral.

METHODS

We surveyed 559 consecutive women bringing a child 18 months of age or less to one of four pediatric primary care sites between July 1996 and May 1997. The pediatric sites included one outpatient program in an academic hospital, one in a community health center, and two in-staff model practices of a managed care organization (these last two were combined for analysis). The self-administered questionnaire contained previously validated questions to assess health behaviors and conditions (smoking, alcohol abuse, depression, violence, risk for unintended pregnancy, serious illness, self-reported health) and access to care (regular source, regular provider, health insurance, care delayed or not received). Maternal attitudes toward a pediatric role in screening and referral were also elicited.

RESULTS

In the three settings, response rates ranged from 75% to 84%. The average age of the women ranged from 25.1 to 32. 1 years and the average age of the children ranged from 6.5 to 8.0 months. Across the settings, the percentage of women reporting at least one health condition (66%-74%) was similarly high, despite significant demographic differences among sites. Many women reported more than one condition (31%-37%); among all women who smoked, 33% also screened positive for alcohol abuse, 31% for emotional or physical abuse, and 48% for depression. Access to comprehensive adult primary care was variable with 23% to 58% of women reporting one or more barriers depending on the site. Across all sites, >85% of mothers reported they would "not mind" or "would welcome" a pediatric role in screening and referral.

CONCLUSIONS

Two-thirds of women bringing their children for pediatric care had health problems regardless of the site of care. Many women also reported substantial barriers to comprehensive health care. Most women reported acceptance of a pediatric role in screening and referral. Given the range and depth of maternal health needs, strategies to connect or reconnect mothers to comprehensive adult primary care from a variety of pediatric settings should be explored.

Policies towards pregnancy and addiction. Sticks without carrots

Throughout this century in the United States, tension has existed between those who believe drug abuse is best combatted through the criminal justice system and those who emphasize a medical/public health model of prevention and treatment. In the last decade this debate has centered around the person of the pregnant addict. The former have construed her addiction as willful harm to the fetus punishable on criminal and child abuse grounds. The latter have countered that pregnancy is a moment of increased motivation for treatment and focused on expansion and improvement of treatment options. Both managed care and welfare reform have exacerbated conditions between these opposing policy approaches. The addicted woman is increasingly caught between policies that punish her drug use without options for overcoming addiction.

Vitamin D replacement in Asians with diabetes may increase insulin resistance

We report three cases of vitamin D replacement in British Asians with vitamin D deficiency and non-insulin-dependent diabetes mellitus. In all cases, replacement resulted in an increase in insulin resistance and a deterioration of glycaemic control.

National survey of the states: policies and practices regarding drug-using pregnant women

OBJECTIVES

This study assessed the impact of national policy shifts on state policies and practices regarding substance-using mothers.

METHODS

A 1995 telephone survey of substance abuse and child protective services directors in all 50 states and the District of Columbia was compared with a similar 1992 survey.

RESULTS

There have been significant increases in state interventions for drug-using pregnant women (e.g., criminal prosecution, toxicology testing of women and neonates). Federal resources for treatment and oversight are being replaced by state control of reduced funds for treatment.

CONCLUSIONS

The earlier policy of expanding treatment for addicted women is being replaced by reduction of services and increased state intervention.

Treatment of vitamin D deficient osteomalacia may unmask autonomous hyperparathyroidism

Two cases of vitamin D deficient osteomalacia with secondary hyperparathyroidism are presented. In both cases treatment with vitamin D replacement therapy resulted in elevated calcium levels and a failure of parathormone levels to normalise, indicating autonomous parathyroid activity. Subsequent surgery in one case resulted in removal of a parathyroid adenoma. The importance of osteomalacia and its complications are discussed.

War experiences and distress symptoms of Bosnian children

OBJECTIVE

The war in Bosnia has had a tremendous impact on civilians. Little is known about the impact of modern warfare on children. This survey documents the nature and frequency of war-related experiences among Bosnian children and describes their manifestations of selected psychological sequelae.

METHODS

A cross-sectional survey of 364 internally displaced 6- to 12-year-old children and their parents living in central Bosnian collectives was conducted during the war. Parents were surveyed for their children's war experiences; the children were surveyed for war-related distress symptoms.

RESULTS

The children were exposed to virtually all of the surveyed war-related experiences. The majority had faced separations from family, bereavement, close contact with war and combat, and extreme deprivation. The prevalence and severity of experiences were not significantly related to a child's gender, wealth, or age, but were related to their region of residence, with children from the region of Sarajevo having the highest prevalence of experiences. Almost 94% of the children met Diagnostic and Statistical Manual of Mental Disorders, 4th ed, criteria for posttraumatic stress disorder. Significant life activity affecting sadness and anxiety were reported by 90.6% and 95.5% of the children, respectively. High levels of other symptoms surveyed were also found. Children with greater symptoms had witnessed the death, injury, or torture of a member of their nuclear family, were older, and came from a large city.

CONCLUSIONS

The war-related experiences of the children studied were both varied and severe, and were associated with a variety of psychological sequelae. This experience underscores the vulnerability of civilians in areas of conflict and the need to address the effects of war on the mental health of children.

Fertility therapy and the risk of very low birth weight

OBJECTIVE

To test the hypothesis of an association between maternal infertility therapy and the risk of very low birth weight (VLBW), defined as birth weight less than 1500 g, independent of the risk of multiple births, and to estimate the contribution of infertility therapy to the national incidence of VLBW.

METHODS

The National Maternal and Infant Health Survey conducted in 1988 was used to develop statistics describing outcomes among this birth cohort and to construct logistic regression models evaluating fertility therapy as an independent risk factor for VLBW.

RESULTS

An estimated 10.1% of live births and 18.2% of VLBW births nationally were associated with either maternal subfertility or infertility therapy (6.8% and 11.4%, respectively). The risk of VLBW among women concerned with subfertility (i.e., receiving diagnostic testing or advice on timing intercourse) was 1.4 (95% confidence interval [CI] 1.1, 1.9), whereas that for women undergoing therapeutic interventions (ie, ovarian stimulation, surgery, in vitro fertilization, or artificial insemination) was 2.6 (95% CI 2.1, 3.2). Accounting for effects of multiple gestation, maternal age, and a history of miscarriage, the odds ratios for the concerned and therapy groups were 1.5 (95% CI 1.1, 1.9) and 2.0 (95% CI 1.5, 2.5), respectively. Black women were less likely to use fertility therapy but more likely to experience a therapy-related VLBW.

CONCLUSION

Fertility therapy is associated with an important portion of all VLBW and with an elevated risk of VLBW, related only in part to an increased risk of multiple gestations. Women expressing concern about subfertility but not receiving therapy are also at increased risk of VLBW, suggesting that a history of infertility may mediate part of the risk associated with fertility therapy.

Maternal and infant health: effects of moderate reductions in postpartum length of stay

BACKGROUND

The Newborns' and Mothers' Health Protection Act of 1996 prohibits payers from restricting "benefits for any hospital length of stay in connection with childbirth for the mother or newborn child, following a normal vaginal delivery, to less than 48 hours." The law recognizes the basic right of women and physicians to make decisions about aptness of discharge timing.

OBJECTIVE

To provide data as a basis for decisions about aptness of discharge timing by studying the effect of voluntary, moderate reductions in length of postpartum hospital stay on an array of maternal and infant health outcomes.

DESIGN

A prospective cohort study. Patients were surveyed by telephone at 3 and 8 weeks postpartum.

SETTING

A teaching hospital where 38% of the patients are in a managed care health plan with a noncompulsory reduced stay program offering enhanced prepartum and postpartum services, including home visits.

PATIENTS

Consecutive mothers discharged after vaginal delivery during a 3-month period.

MAIN OUTCOME MEASURES

The outcomes were health services use within 21 days, breast-feeding, depression, sense of competence, and satisfaction with care. Multivariate analyses adjusted for sociodemographic factors, payer status, services, and social support.

RESULTS

Of 1364 eligible patients, 1200 (88%) were surveyed at 3 weeks; of these 1200, 1015 (85%) were resurveyed at 8 weeks. The mean length of stay was 41.9 hours (SD, 12.2 hours). Of patients going home in 30 hours or less, 60.8% belonged to a managed care health plan. The length of stay was not related to the outcomes, except that women hospitalized shorter than 48 hours had more emergency department visits than those staying 40 to 48 hours (adjusted odds ratio, 5.78; 95% confidence interval, 1.19-28.05).

CONCLUSIONS

When adequate postpartum outpatient care is accessible, a moderately shorter length of postpartum stay after an uncomplicated vaginal delivery had no adverse effect on an array of outcomes. Researchers and policy makers should seek to better define the content of postpartum services necessary for achieving optimal outcomes for women and newborns; funding should be available to provide such services, regardless of the setting in which they are provided.

Risk status at discharge and cause of death for postneonatal infant deaths: a total population study

OBJECTIVES

To obtain population-based, clinical information regarding potentially modifiable factors contributing to death during the postneonatal period (28 to 364 days), we examined all postneonatal infant deaths in four areas of the United States to determine: (1) the cause of death from clinical and autopsy data rather than vital statistics, (2) whether death occurred during initial hospitalization or after discharge, and (3) the portion of postneonatal mortality attributable to infants who left the hospital with identified high-risk medical conditions.

DESIGN AND SETTING

Retrospective medical record review of all postneonatal infant deaths with birth weights greater than 500 g (total N = 386) born to mothers residing in: (1) the city of Boston (1984 and 1985, N = 55), (2) the city of St Louis and contiguous areas (1985 and 1986, N = 123), (3) San Diego County (1985, N = 112), and (4) the state of Maine (1984 and 1985, N = 96). Deaths were identified using linked birth and death vital statistics, and medical record audits of infants' and mothers' charts were performed. Causes of death were obtained from medical record review in conjunction with autopsy if performed (72%, N = 278), medical record alone (17%, N = 67), or vital statistics if no other source was available (11%, N = 41). The medical conditions at the time of discharge for each infant were reviewed and, if judged to confer an increased risk of morbidity or mortality, were classified as high risk.

RESULTS

The causes of death were sudden infant death syndrome (47%, N = 181), congenital conditions (20%, N = 77), prematurity-related conditions (11%, N = 43), infections (9%, N = 34), external causes (including injuries, drownings, ingestions, and burns) (7%, N = 25), and other (6%, N = 23). In 24% of congenital and 25% to 44% of prematurity-related deaths, infection was the acute or associated cause of death. Infants born to black mothers were more likely than those born to white mothers to die during the postneonatal period of all major causes of death (7.3 per 1000 vs 3.0 per 1000). Overall, 18% (N = 68) of deaths occurred to infants who never left the hospital; 79% (N = 305) of the infants were discharged before death; and discharge status was unknown in 3% (N = 13). Eighty-one percent of all infants with prematurity-related postneonatal deaths were never discharged, and of the total infants who were initially discharged, only 1% (N = 4) subsequently died of prematurity-related causes. Of all postneonatal deaths, only 16% (N = 62) left the hospital with identified high-risk medical conditions.

CONCLUSIONS

These findings suggest that the etiology of postneonatal mortality is heterogeneous, with significant complexity in attributing specific causes of death and making designations of "preventability." The vast majority of infants who died of prematurity-related postneonatal causes never left the hospital, and only a small percentage of all infants that left the hospital before death were identified as being at high medical risk. Therefore, strategies for further decreasing postneonatal mortality must link high-risk follow-up programs to more comprehensive strategies that address risk throughout pregnancy and early childhood.

High variability of glycated hemoglobin concentrations in patients with IDDM followed over 9 years. What is the best index of long-term glycemic control?

OBJECTIVE

To determine variability of long-term glycemic control in patients with IDDM.

RESEARCH DESIGN AND METHODS

A retrospective analysis of HbA1 among 122 IDDM patients followed over 9 years.

RESULTS

Annual group mean HbA1 ranged from 8.4 to 9.3% with large standard deviations (1.7-2.0%), indicating marked variability among individuals. Fluctuations of more than +/- 1% HbA1 occurred in 50% of the patients year to year, and over 9 years the minimum-maximum range was > 3 and > 5% HbA1 in 55 and 11% of patients, respectively. In any one year, 22-43% of patients had HbA1 < 8%, but over 9 years only 3.3% were consistently < 8%. Groups divided according to baseline HbA1 of < 8, 8-10, and > 10% were significantly separated over 9 years by frequency distribution analysis of individual mean HbA1 but were indistinguishable when analyzed by individual HbA1 interquartile range (measure of variability).

CONCLUSIONS

High variability of long-term glycemic control is a marked feature of IDDM, the extent of which may be relevant to microvascular risk.

Inadequate hepatitis B vaccination of adolescents and adults at an urban community health center

Hepatitis B remains a major public health problem in the United States, but public vaccination policy has targeted infants rather than the high-risk adults who constitute the vast majority of patients at imminent risk of infection. The effects of this policy were studied at a community health center in Boston. Adolescents and adults who attended a community health center between January 1, 1992 and May 31, 1993 and had human immunodeficiency virus (HIV) or another sexually transmitted disease (STD)--indications for vaccination according to the Centers for Disease Control and Prevention--were identified through chart review. The vaccination rate and missed opportunities were determined. In addition, directors of Boston health centers were surveyed on hepatitis B vaccine at their clinics. Of 178 individuals with HIV or another STD and without serologic evidence of prior exposure to hepatitis B, two (1.1%) received the vaccine. There were 342 missed opportunities. Only two of 14 medical directors said their clinics routinely offered vaccine to individuals with STDs. The medical directors rated financial barriers as more important obstacles to hepatitis B vaccination than nonfinancial barriers. These results indicate that many high-risk adolescents and adults do not receive a preventive intervention that is federally recommended, potentially life saving, and cost effective. Inadequate public funding for vaccine may be a key barrier for this population.

Home uterine activity monitoring in the prevention of very low birth weight

OBJECTIVES

Despite controversy regarding the efficacy of home uterine activity monitoring (HUAM), it is currently licensed for detection of preterm labor in women with previous preterm deliveries. In practice, however, it is being more widely utilized in an effort to prevent preterm delivery. This study seeks to determine which group of mothers delivering very low birth weight (VLBW) infants would have qualified for HUAM given three different sets of criteria and in which women it could have been used to help prolong gestation.

METHODS

The authors reviewed the medical records of mothers of VLBW infants born in five U.S. locations (N = 1440), retrospectively applying three sets of eligibility criteria for HUAM use: (a) the current FDA licensing criterion for use of HUAM, a previous preterm birth; (b) indication for HUAM commonly cited in published reports; (c) a broad set of criteria based on the presence of any reproductive or medical conditions that might predispose to premature delivery. The authors then analyzed the conditions precipitating delivery for each group to determine whether delivery might have been prevented with HUAM and tocolytic therapy.

RESULTS

Only 4.4% of the total group of women delivering VLBW infants would have been eligible for HUAM under the FDA criterion and might potentially have benefited from this technology. If extremely broad criteria had been applied to identify those eligible for monitoring, under which almost 80% of all women who delivered VLBW infants would have been monitored, only 20.3% of the total group would have been found eligible and would potentially have benefited. If such broad criteria were applied to all pregnant women, a sizable proportion of pregnancies would be monitored at great expense with small potential clinical benefit.

CONCLUSIONS

Because VLBW births are usually precipitated by conditions that are unlikely to benefit from HUAM, this technology will have little impact on reducing VLBW and neonatal mortality rates. More comprehensive preventive strategies should be sought.

The first injustice: socioeconomic disparities, health services technology, and infant mortality

"Infant mortality has long been viewed as a synoptic indicator of the health and social condition of a population. In this article we examine critically the structure of this reflective capacity with a particular emphasis on how new health care technologies may have altered traditional pathways of social influence.... Current patterns of infant mortality in the United States provide a useful illustration of the dynamic interaction of underlying social forces and technological innovation in determining trends in health outcomes. We review the implications of this perspective for [future] sociological research into disparate infant mortality...."

Racial disparities in outcomes of military and civilian births in California

OBJECTIVE

To examine racial disparities in prenatal care utilization, birth weight, and fetal and neonatal mortality in a population for whom financial barriers to health care services are minimal.

STUDY-DESIGN

Using linked birth, fetal death, and infant death certificate files, we examined prenatal care utilization, birth weight distribution, and fetal and neonatal mortality rates for all white and black births occurring in military hospitals in California from January 1, 1981, to December 31, 1985. These patterns were compared with the experience of their civilian counterparts during the same time period.

RESULTS

Black mothers had higher percentages of births occurring in teenaged and unmarried mothers than did white mothers in military and civilian populations. First-trimester prenatal care initiation was lower for blacks in the military (relative risk, 0.79; 95% confidence interval, 0.75-0.82) and civilian (relative risk, 0.51; 95% confidence interval, 0.50-0.52) populations. However, the scale of the disparity in prenatal care utilization was significantly smaller (P < .001) in the military group. Rates of low birth weight and fetal and neonatal mortality among blacks were elevated in the military and civilian groups. However, the racial disparity in low birth weight was significantly smaller in the military group (P < .01 and P < .001, respectively).

CONCLUSIONS

In populations with decreased financial barriers to health care, racial disparities in prenatal care use and low birth weight were reduced. However, the persistence of significant disparities suggests that more comprehensive strategies will be required to ensure equity in birth and neonatal outcome.

The influence of the wider use of surfactant therapy on neonatal mortality among blacks and whites

BACKGROUND

Surfactant therapy reduces morbidity and mortality among premature infants with the respiratory distress syndrome (RDS). Fetal pulmonary surfactant matures more slowly in white than in black fetuses, and therefore RDS is more prevalent among whites than among blacks. We reasoned that the increased use of surfactant after its approval by the Food and Drug Administration (FDA) in 1990 might have reduced neonatal mortality more among whites than among blacks.

METHODS

We merged vital-statistics information for all 1563 infants with very low birth weights (500 to 1500 g) born from 1987 through 1989 or in 1991 and 1992 to residents of St. Louis with clinical data from the four neonatal intensive care units in the St. Louis area; we then compared neonatal mortality during two periods, one before and one after the FDA's approval of surfactant for clinical use (1987 through 1989 and 1991 through 1992).

RESULTS

The use of surfactant increased by a factor of 10 between 1987 through 1989 and 1991 through 1992. The neonatal mortality rate among all very-low-birth-weight infants decreased 17 percent, from 220.3 deaths per 1000 very-low-birth-weight babies born alive (in 1987 through 1989) to 183.9 per 1000 (in 1991 through 1992; P = 0.07). This decrease was due to a 41 percent reduction in the mortality rate among white newborns with very low birth weights (from 261.5 per 1000 to 155.5 per 1000; P = 0.003). In contrast, among black infants, the mortality rate for very-low-birth-weight infants did not change significantly (195.6 per 1000 and 196.8 per 1000). The relative risk of death among black newborns with very low birth weights as compared with white newborns with similar weights was 0.7 from 1987 through 1989 and 1.3 from 1991 through 1992 (P = 0.02). The differences in mortality were not explained by differences in access to surfactant therapy, by differences in mortality between black and white infants who received surfactant, or by differences in the use of antenatal corticosteroid therapy.

CONCLUSIONS

After surfactant therapy for RDS became generally available, neonatal mortality improved more for white than for black infants with very low birth weights.

The importance of extreme prematurity and low birthweight to US neonatal mortality patterns: implications for prenatal care and women's health

OBJECTIVE

In order to frame the appropriateness of neonatal mortality reduction efforts that begin only after pregnancy is recognized, this study examined the relative contributions of different gestational age and birthweight groups to total neonatal mortality and to racial disparities in neonatal mortality in the United States.

METHODS

Using the national linked birth/infant death data set for the 1988 cohort, the relative contributions of different birthweight and gestational age groups to national neonatal mortality rates were calculated. The relative contributions of these groups to the racial disparity in neonatal mortality were also assessed.

RESULTS

Very low birthweight infants (< 1,500 g) accounted for 1.2% of all births, but 64.2% of all neonatal deaths. The very low birthweight rate for whites was 0.93%, while that for blacks was 2.79% with the contribution of this group to neonatal mortality higher for blacks than whites. Infants less than 1,000 g contributed more than 80% of the racial disparity in neonatal mortality.

CONCLUSION

Neonatal mortality patterns in the United States have become highly dependent on infants with gestational ages that approach the second trimester. Preventing neonatal mortality by enhancing care only after pregnancy has been recognized, therefore, may be limited. Strategies that link prenatal care to broader initiatives to improve the health of women regardless of pregnancy status may be more effective.

Mortality rates among 15- to 44-year-old women in Boston: looking beyond reproductive status

Mortality rates were examined for Boston women, aged 15 to 44, from 1980 to 1989. There were 1234 deaths, with a rate of 787.8/100,000 for the decade. Leading causes were cancer, accidents, heart disease, homicide, suicide, and chronic liver disease. After age adjustment, African-American women in this age group were 2.3 times more likely to die than White women. Deaths at least partly attributable to smoking and alcohol amounted to 29.8% and 31.9%, respectively. Mortality was found to be related more directly to the general well-being of young women than to their reproductive status, and many deaths were preventable. African-American/White disparities were most likely linked to social factors. These findings suggest that health needs of reproductive-age women transcend reproductive health and require comprehensive interventions.

The impact of extreme prematurity and congenital anomalies on the interpretation of international comparisons of infant mortality

OBJECTIVE

To identify the potential impact that different definitions of live births and practice patterns have on infant mortality rates in England and Wales, France, Japan, and the United States.

METHODS

United States data were obtained from the 1986 linked national birth-infant death cohort, and those for the other countries came from either published sources or directly from the Ministries of Health.

RESULTS

In 1986 in the United States, infants weighing less than 1 kg accounted for 36% of deaths (32% white and 46% black); 32% resulted from fatal congenital anomalies. These rates were much higher in both categories than in England and Wales in 1990 (24 and 22%, respectively), France in 1990 (15 and 25%, respectively), and Japan in 1991 (9% for infants weighing less than 1 kg, percentage of fatal congenital anomalies unknown). These cases are more likely to be excluded from infant mortality statistics in their countries than in the United States.

CONCLUSIONS

In 1990, the United States infant mortality rate was 9.2 per 1000 live births, ranking the United States 19th internationally. However, infant mortality provides a poor comparative measure of reproductive outcome because there are enormous regional and international differences in clinical practices and in the way live births are classified. Future international and state comparisons of reproductive health should standardize the definition of a live birth and fatal congenital anomaly, and use weight-specific fetal-infant mortality ratios and perinatal statistics.

The accessibility of drug treatment for pregnant women: a survey of programs in five cities

Through simulated calls to 294 drug treatment programs in five cities, this study investigated access for pregnant women and compared New York City's provision of services in 1989 to that in 1993. In all sites, the majority of programs accepted pregnant women. There was also a marked improvement in the availability of services in New York City. Yet options were more limited for Medicaid recipients and women needing child care, and an appointment or referral for prenatal care was usually not offered. Although the door for treatment may be opening for pregnant women, institutional barriers still remain.

Effect of advertising on awareness of symptoms of diabetes among the general public: the British Diabetic Association Study

OBJECTIVE

To determine the impact of posters advertising symptoms of diabetes on public knowledge of these symptoms.

DESIGN

Structured street interviews of members of the general public before, at the end of, and 10 weeks after a campaign advertising the main symptoms of diabetes.

SETTING

Basingstoke and Wolverhampton.

SUBJECTS

Three samples of 1000 members of the general public were interviewed. Samples were selected randomly but stratified to match the local population's age (20-75), sex, social class, and racial characteristics.

MAIN OUTCOME MEASURES

Knowledge of symptoms of diabetes; perceived seriousness of diabetes; and induction of anxiety about symptoms in the target population.

RESULTS

Advertising significantly raised knowledge (without prompting) of symptoms: thirst, 245 before v 411 at end of campaign (P < 0.0001) v 341 after (P = 0.0012 v before); polyuria, 72 v 101 (P = 0.0211) v 92 (P = 0.5169); lethargy, 180 v 373 (P < 0.0001) v 298 (P < 0.0001); knowledge of weight loss and visual disturbance was unaffected. The number of subjects lacking knowledge of any symptoms was reduced from 550 to 388 (P < 0.0001). The perceived seriousness of diabetes was unaffected (mean 7.6 in each phase on a scale of 1 (not) to 10 (very). Before advertising, 449 (45%) claimed to have one or more symptoms of diabetes, but this number fell at the end of the campaign (403; P = 0.0419) and 10 weeks afterwards (278; P < 0.0001).

CONCLUSIONS

An advertising campaign raised public knowledge of diabetes symptoms without inducing fear of diabetes or anxiety about symptoms. Its potential for achieving earlier detection of non-insulin dependent diabetes should be evaluated.

Finding common ground: the necessity of an integrated agenda for women's and children's health

During the past decade, a new term has entered the medical/legal lexicon : maternal-fetal conflict. Implicit in the terminology is the assumption that a pregnant woman and her fetus have separate and competing rights. This concept has stimulated extensive legal and ethical debate, primarily in the context of medical interventions (cesarean sections and blood transfusions) forced on unwilling pregnant women, and in corporate efforts to bar fertile women from hazardous jobs. On one side of the debate are the proponents of the future child's right to be born of sound mind and body, and society's interest in the delivery of healthy newborns. On the other side, are advocates of a woman's right to reproductive autonomy, bodily integrity, due process, confidential medical treatment, and freedom from gender discrimination. Neither side has challenged the formulation of the problem, or has examined its permeation into public health policy.

Comparison of paired short Synacthen and insulin tolerance tests soon after pituitary surgery

The cortisol responses to hypoglycaemia (insulin tolerance test, ITT) and tetracosactrin (short Synacthen test, SST) were compared after hypophysectomy to evaluate the SST for the assessment of hypothalamo-pituitary-adrenocortical (HPA) axis function in the immediate post-operative period. In 12 patients who were tested a mean of 21 months postoperatively (range 1-96) peak plasma cortisol in the SST correlated with that in the ITT (r = 0.90). Correlation was also seen in 12 patients tested a mean of 9 days (range 4-18) after hypophysectomy (r = 0.73). Basal-peak cortisol increments did not correlate. The peak plasma cortisol response in each test was classified by comparison with a reference value of 550 nmol/L. On this basis there was a notable discrepancy between the ITT and SST results in only one patient who was tested 4 days after hypophysectomy. The close correlation between ITT and SST responses after pituitary surgery extends into the immediate post operative period and indicates that the latter test can be used to screen HPA axis function at this time.

Confronting racial disparities in infant mortality: reconciling science and politics

The public debate surrounding disparities in infant mortality has resulted from a profound failure to seek a common wisdom. Because of its essential social roots, infant mortality will always remain the province of fundamental ideological and political conflict. However, without a more integrated analytic approach, progress in reducing disparate infant mortality will remain limited by internecine struggles for disciplinary purview and false claims of societal relevance. For in the end, the struggle to address disparate infant mortality will be advanced best by integrated technical and political strategies that recognize that the pursuits of efficacy and justice are inextricably linked.

Infant mortality

Infant mortality continues to be a major public health issue in the United States. Although some preventive strategies for neonatal mortality are emerging for congenital malformations, notably neural tube defects, the prevention of preterm deliveries among disadvantaged populations remains elusive, suggesting the need for different approaches to women's health needs. Despite the lack of success in preventing preterm birth, neonatal mortality rates continued to decline substantially, a decline attributed to improvements in neonatal intensive care associated with surfactant use. The increasing survival of very preterm infants continues to raise questions about their longer term outcomes especially with several recent studies on difficulties in school, and about the need for postdischarge developmental interventions. Attempts to decrease postneonatal mortality received marked attention with the recommendations for specific positioning to prevent sudden infant death syndrome and heightened attention to increased immunization completion rates. The dismal ranking of the United States in infant mortality rates among industrialized countries, however, continues to present a social policy challenge.

Restriction fragment length polymorphisms of the human aldose reductase gene: a preliminary report

Abnormal metabolism through the polyol pathway during episodes of hyperglycaemia is implicated in the development of the chronic complications of diabetes. Since aldose reductase is the first and ratelimiting enzyme of the polyol pathway, it is predicted that restriction fragment length polymorphisms at the aldose reductase gene locus may influence catalytic activity and determine individual susceptibility to the diabetic complications. This paper reports the existence of EcoRI and TaqI restriction fragment length polymorphisms at the human aldose reductase locus.

Prevalence of haemochromatosis amongst patients with diabetes mellitus

Four hundred and six white caucasian patients with diabetes mellitus (243 male, mean age 54 +/- 16 (SD) years) were screened for haemochromatosis. Four patients had a fasting transferrin saturation > 62% and all were HLA A3 positive. Two were probable homozygotes for haemochromatosis and two heterozygotes. Homozygote haemochromatosis prevalence in this diabetic population was therefore 2/406 (0.0049) which is identical to that reported in the general population. These findings do not support a genetic relationship between the two conditions.

Clinical determinants of the racial disparity in very low birth weight

BACKGROUND

Although the risk of very low birth weight (less than 1500 g) is more than twice as high among blacks as among whites in the United States, the clinical conditions associated with this disparity remain poorly explored.

METHODS AND RESULTS

We reviewed the medical records of over 98 percent of all infants weighing 500 to 1499 g who were born in Boston during the period 1980 through 1985 (687 infants), in St. Louis in 1985 and 1986 (397 infants), and in two health districts in Mississippi in 1984 and 1985 (215 infants). The medical records of the infants' mothers were also reviewed. These data were linked to birth-certificate files. During the study periods, there were 49,196 live births in Boston, 16,232 in St. Louis, and 16,332 in the Mississippi districts. The relative risk of very low birth weight among black infants as compared with white infants ranged from 2.3 to 3.2 in the three areas. The higher proportion of black infants with very low birth weights was related to an elevated risk in their mothers of major conditions associated with very low birth weight, primarily chorioamnionitis or premature rupture of the amniotic membrane (associated with 38.0 percent of the excess proportion of black infants with very low birth weights [95 percent confidence interval, 31.3 to 45.4 percent]); idiopathic preterm labor (20.9 percent of the excess [95 percent confidence interval, 16.0 to 26.4 percent]); hypertensive disorders (12.3 percent [95 percent confidence interval, 8.6 to 16.6]); and hemorrhage (9.8 percent [95 percent confidence interval, 5.5 to 13.5]).

CONCLUSIONS

The higher proportion of black infants with very low birth weights is associated with a greater frequency of all major maternal conditions precipitating delivery among black women. Reductions in the disparity in birth weight between blacks and whites are not likely to result from any single clinical intervention but, rather, from comprehensive preventive strategies.
