The influence of observation and setting on community health workers' practices.

OBJECTIVE: To determine whether results from an evaluation that involved observation of community health workers while they performed patient consultations in a hospital reflected normal everyday practices. DESIGN: Comparison of two samples of ill-child consultations: (i) consultations performed during an evaluation in which we observed community health workers in a hospital in-patient and outpatient department from February to March 2001 and (ii) consultations performed under no observation in villages and documented in clinical registers within the 90 days before the hospital evaluation. SETTING: Siaya District Hospital and villages in Kenya. STUDY PARTICIPANTS: Community health workers. MAIN OUTCOME MEASURE: Treatment error indicator, defined as the percentage of consultations where at least one recommended treatment (where recommended treatments were those that were indicated based on community health worker assessments of the child's condition) was not prescribed. RESULTS: We analyzed data on 1132 consultations (372 from the hospital evaluation and 760 from the community) performed by 103 community health workers. For all types of consultations combined, the difference between treatment error indicators (hospital minus community) was -16.4 [95% confidence interval (CI): -25.6, -7.1]. CONCLUSIONS: We found that community health workers made treatment errors less frequently when they were observed in a hospital in-patient or outpatient department than when they were not observed in the community. Evaluations that involve the observation of community health workers in a hospital setting might overestimate the quality of care that they normally give in their villages.

The check box: determining pregnancy status to improve maternal mortality surveillance.

OBJECTIVE: More than half of pregnancy-related deaths are not identified through routine surveillance methods. The purpose of this study was to evaluate the effectiveness of the pregnancy check box on death certificates in ascertaining pregnancy-related deaths. METHODS: Data derived from the Centers for Disease Control and Prevention's ongoing Pregnancy Mortality Surveillance System were used to identify states that included a check box on the death certificate in 1991 and 1992. Death certificates from those states were evaluated to determine the number and proportion of pregnancy-related deaths identified by a marked check box. Characteristics of death were also examined. RESULTS: Sixteen states and New York City included a check box or question specifically asking about pregnancy of the decedent. Of the 425 pregnancy-related deaths identified in the 17 reporting areas, 124 (29%) were determined to be pregnancy-related deaths only because of the pregnancy status information provided in the check box. The proportion of deaths identified only by a marked check box ranged from less than 5% for four states to 40% or more for seven states. CONCLUSIONS: The availability of pregnancy status information on death certificates is a simple and effective aid in ascertaining a pregnancy-related death, when no other indicators of pregnancy appear on the death certificate. Routine use of the pregnancy check box for all states would lead to substantially increased classification of maternal deaths and more accurate classification of the causes of and risk factors for maternal deaths.

Trends and predictors of infant sleep positions in Georgia, 1990 to 1995.

BACKGROUND: In recent years, the prone sleeping position has emerged as the strongest modifiable risk factor for sudden infant death syndrome, the leading cause of infant mortality between 1 month and 1 year of age in the United States. Since April 1992, sudden infant death syndrome risk-reduction strategies have included the promotion of the back or side sleeping position (nonprone) for healthy infants younger than 1 year of age. Most recently, the back position has been advocated as the best sleeping position and the side position as an alternative. METHODS: To evaluate trends in prevalence of the prone position from 1990 to 1995, we used data available from the Georgia Women's Health Survey, a random digit-dialed telephone survey of 3130 women 15 to 44 years of age. We examined the position in which women put their infant to sleep in the first 2 months of life for their most recent live birth (N = 868) and determined independent predictors of prone sleep position among women who consistently used the prone or the back/side position (n = 636) using multiple logistic regression. RESULTS: The prevalence of mothers who put their infant to sleep in the prone position significantly decreased, from 49% in 1990 to 15% in 1995. This decrease is primarily attributable to a major shift to the side position rather than to the back. Using multiple logistic regression, we found the prone sleeping position to be significantly higher among women who entered prenatal care after the first trimester (odds ratio [OR], 3.6; 95% confidence interval [CI], 1.4-9.2), were black (OR, 2.1; 95% CI, 1.4-3.1), had less than a high school education (OR, 2.2; 95% CI, 1.4-3.4), and were living in rural Georgia (OR, 1.9; 95% CI, 1.3-2.7). For the period after April 1992, women who had previous children were 2.6 (OR, 95% CI, 1.7-4.1) times more likely to use the prone sleep position than were first-time mothers. CONCLUSIONS: The prevalence of the use of the prone sleep position for infants decreased significantly over the study period. This decrease coincided with national efforts to promote the back or side sleeping position. Increased efforts should target groups who are more likely to use the prone position to attain the national goal of </=10% of prone position prevalence by the year 2000, with emphasis on placing the infant on the back.

National trends in the incidence of abruptio placentae, 1979-1987.

Premature separation of the normally implanted placenta is a serious complication of pregnancy and a leading cause of maternal and perinatal morbidity and mortality. Using data from the National Hospital Discharge Survey, we estimated rates of abruptio placentae in the United States for the years 1979-1987 and examined the association of this condition with several demographic risk factors and coexisting obstetric conditions. In 1987, the national rate was 11.5 cases per 1000 deliveries. The rate of abruptio placentae increased significantly between the years 1979-1987 among women of all racial groups. The increase in the rate of placental abruption occurred mainly among women under the age of 25, unmarried women, and women on Medicaid compared with those who had private insurance. Women with placental abruption were 54 times more likely to have coagulopathies and 11 times more likely to have stillbirths than those without placental abruption. Twin gestations, preterm premature rupture of membranes, chorioamnionitis, chronic hypertension, and preeclampsia/eclampsia were also associated with placental abruption. Although the cause for the increase in the incidence of abruptio placentae is not known, most of the increase occurred among women likely to be financially and socially disadvantaged.

A thirty-year review of maternal mortality in Oklahoma, 1950 through 1979.

Oklahoma's Maternal Mortality Committee has been active since 1941. During the 30-year period 1950 through 1979, the committee reviewed in detail 75.9% of the pregnancy-related deaths that occurred in Oklahoma. The maternal mortality ratio in 1950 was 95.1/100,000 live births, and for 1979 it was 8.1/100,000 live births, a decrease of 91.5%. The risk of death from childbearing remained greater for black women than for American Indian or white women throughout the three decades. For American Indian women, the risk of death associated with pregnancy has decreased and is almost equal to the risk for white women. The Maternal Mortality Committee estimated that two thirds of Oklahoma's maternal deaths were preventable. The proportion of deaths judged preventable did not vary substantially during the study period. We conclude that maternal mortality in Oklahoma can be reduced to fewer than three deaths per 100,000 live births. Intensive monitoring and investigation of deaths and their causes by local maternal mortality committees continues to be an important mechanism for obtaining information to assist health workers in the prevention of deaths.

[Alcoholism and society: secondary and tertiary prevention by directly concerned persons].

Alcohol (especially wine) production and consumption is very much ingrained in the culture and behaviors in Switzerland, especially in the French speaking part. This makes the fate of people with an alcohol problem particularly difficult, as they have to face their addiction, and an attitude of society which is very tolerant for drinking but rather hostile to them. Giving up alcohol means tremendous loss for the drinker, in various ways. With objectives of secondary and especially tertiary prevention, a private association was created in the 1960's, offering to alcoholics opportunities for meeting, discussing their problems, playing. A country house is used for holding retreats. And a home, l'Esterelle, was opened in Vevey in 1966, to house abstinent alcoholics during the rehabilitation phase. Leadership role in these endeavours are assumed by former drinkers.

The Food and Drug Administration and medroxyprogesterone acetate. What are the issues?

In 1978, the Food and Drug Administration denied approval of the three-month injectable contraceptive depot medroxyprogesterone acetate for use in the United States. This decision goes against the advice of the FDA's own scientific advisory panels, as well as the rulings of the World Health Organization and the drug regulation institutions of more than 70 developed and developing countries. In response to protest from the manufacturer of depot medroxyprogesterone acetate and from many health professionals, the FDA took the unusual step of scheduling a public board of inquiry to review its decision in January 1983. Reviewing the scientific literature on the risks and benefits of depot medroxyprogesterone acetate, we find no reason to deny depot medroxyprogesterone acetate approval, provided that studies of its possible side effects are continued and that women use it only after having made an informed choice between this and other methods of contraception.

Epidemiologic differences between sexual and physical child abuse.

Sexual and physical child abuse are assumed to differ; however, these differences have not been well characterized epidemiologically. Furthermore, despite assumed differences, these types of abuse are often analyzed as one entity. This can have significant effects on assessment of risk and recommendations for intervention. We compared 735 cases of sexual abuse and 3,486 cases of nonsexual physical abuse confirmed by the Georgia Department of Protective Services. Sexual and physical child abuse cases differed in age, sex, and relationship of perpetrators and victims; demographic and socioeconomic characteristics of families at risk; and morbidity and mortality caused by the event. The most important recommendation based on these findings is that epidemiologically distinct forms of child abuse must be analyzed separately before intervention measures are proposed.

The epidemiology of neonatal death in twins.

The epidemiology of twin pregnancies was studied with the use of data on 7,001 live-born twins from the Georgia neonatal surveillance network for the period 1974-1978. A cesarean section did not appreciably reduce the risk of neonatal death for a twin with a vertex presentation. The relative risk of such a neonatal death was 1.4 after adjustment was made for birth weight. A cesarean section did improve the outcome for breech and other presentations. Twins had a sixfold higher neonatal mortality rate than had singleton infants (p less than 0.001), which can be explained on the basis of distribution of birth weights. Twins had a weight-specific mortality rate equivalent to or significantly less than that for singletons after adjustment was made for birth weight. The relative risk of neonatal death for Twin 2 compared with Twin 1 was not significant. Breech presentation was more common in twins than in singletons, and for Twin 2 more than for Twin 1. As birth weight increased, the number of breech presentations decreased for Twin 2 but not for Twin 1. To reduce the high neonatal mortality rate for twins, the objective should be to reduce the incidence of low-birth-weight twins, rather than to increase the cesarean section rate for them.

Reproductive mortality in Lusaka, Zambia, 1982-1983.

In this study, age- and parity-specific birth data were used to estimate maternal mortality rates for 1982-83 at University Teaching Hospital in Lusaka, Zambia. Overall, 60 maternal deaths occurred during pregnancy or within 42 days after pregnancy termination, and four pregnancy-related deaths occurred more than 42 days after pregnancy termination. Nine of the 60 maternal deaths were caused by induced abortion, one by spontaneous abortion, twelve by hypertensive disease of pregnancy, ten by hemorrhage, nine by puerperal sepsis, and four by ectopic pregnancy. Of the 12 women who died from nonobstetric causes, one committed suicide because of an unwanted pregnancy. Women aged 35 years and older or who had had four previous pregnancies had a higher risk of dying than other women, especially by hemorrhage. The chief risk factors included not using an effective method of contraception, using an unsafe means to terminate unintended pregnancies, lack of prenatal care, refusing a blood transfusion (for religious reasons), and inadequately treating hypertensive disease of pregnancy. Overall, 31 of 60 women who died lacked adequate or appropriate medical care and 19 failed to obtain available health care. Medical management problems appeared to occur more frequently during the night-time medical shift.
