Record linkage was used to identify births in 1974 to patients who had received contraceptive services from public family planning clinics in metropolitan Atlanta. The record linkage methodology is described. Results indicated that patient educational level, age. contraceptive choice, and race were the factors most associated with subsequent patient fertility. Black teenage patients experienced the highest fertility. Patients age 20 years and over with some education beyond high school experienced approximately one-third the fertility of less-educated patients. The program effectiveness of the IUD and the Pill was substantially better than that of foam and condoms. Excluding teenagers, the program effectiveness of the IUD was better than the Pill, Changes in family planning services for high-risk patients may help them achieve their- fertility control objectives. Linking family planning clinic records to official birth records as described in this study can help determine clinic success in meeting patient objectives. Other applications of record linkage are discussed briefly. [ABSTRACT FROM AUTHOR]

Widespread publicity in the mass media about the dangers of leaving an IUD in place in a pregnant uterus was apparently more effective than traditional scientific publication and drug package inserts in getting doctors to remove devices from pregnant patients. This suggests that such publicity could be effective in improving clinical practice and the public health in other instances, such as getting doctors to prescribe and women to request birth control pills with lower doses of estrogen, and persuading women to obtain early rather than the riskier midtrimester abortions.

The Center for Disease Control (CDC), Atlanta, Georgia implemented an eight-month prospective surveillance system in 24 hospitals distributed among states with and without public funding for abortion. Out of 3,157 visits for abortion-related complications, only 10 women gave a history of non-physician or self-induced abortion and none were Medicaid recipients. The small number of hospitals located in non-funded states and the smaller numbers of women served in these hospitals than in the funded states limited the power of out study. Women living along the Texas-Mexico border appeared more likely to have complications after illegal abortions than women from other areas of the country.

We reviewed the neonatal outcome of 3,369 infants who weighed less than or equal to 1500 grams and who were born in Georgia during the years 1974--76. We matched 1,465 of these infants with a death certificate registered in the State's Vital Records. Upon review of the hospital records of the remaining infants, we identified 453 infants that died during the neonatal period without a death certificate being registered. Subsequently, we compared the hospital death registries for 1977 in Georgia and death certificates registered in Vital Records during 1977. We identified an additional 236 infants who died without a death certificate being registered. Forty per cent of these infants weighed greater than 1500 grams. Two major procedural errors regarding the filing of death certificates in Georgia at the local level contributed to this 21 per cent underregistratioon of neonatal deaths in 1974--77. The underregistration occurred disproportionately for rural areas, for unmarried mothers, and for Black infants. The reason for underregistration included failure of hospitals and morticians to file death certificates with the county registrars.

From July 1975 through December 1979, the Georgia Department of Protective Services Central Registry recorded population-based data on confirmed, non-confirmable, and ruled-out child abuse reports. We propose that reporting biases are reflected in the differential characteristics of confirmed and ruled-out reports of child abuse. Characteristics, households, or groups equally or more prevalent in the latter category cannot necessarily be considered associated with increased risk of child abuse, even if they are represented in the confirmed abuse population more than in the general public. Important examples of factors or categories for which an association was suggested in other studies but which are not supported by this analysis are: urban residence, teenage motherhood, infancy, and mothers and other female perpetrators. These are conditions or categories associated with greater surveillance; therefore, risk assessment is not possible using the data in this registry. Certain households do appear to be at increased risk for child abuse. These include large families, families without a biological mother or biological father, and families ever needing Aid to Families with Dependent Children (AFDC). This increased risk, however, is slight. Improved surveillance requires identification of reporting biases. A comparison of confirmed and ruled-out reports is an inexpensive and system-specific step toward achieving this aim.

Homicide rates for infants dropped suddenly between 1967 and 1969. The abrupt nature of this decline suggested the change was artifactual. Investigation suggests that two classification revisions instituted at this time were causes of this decline: changes in related codes set forth in the Eighth Revision of the International Classification of Diseases, Adapted, and revision of the standard certificate of death in 1968. Infant homicides may have been disproportionately underrecorded after 1968. (Am J Public Health 1983; 73:195-197.)

In 1983, the State Epidemiologists in 46 States completed a survey questionnaire describing the professional qualifications, training, and experience of State health department epidemiologists and the scope of participation by the State Epidemiologists and their staffs in public health programs. The survey identified 224 State health department epidemiologists (estimated U.S. ratio 1.1 per million population). A State health department epidemiologist was most often male (80 percent), frequently (57 percent) was a physician, had an average age of 41 years, and had worked as an epidemiologist for 9 years. Participation in public health programs (either by supervising or providing consultation) by the State Epidemiologists and their staffs focused mainly on general epidemiology and communicable disease programs; fewer than half had participated in programs relating to the health of women and children, chronic diseases, injuries, or in other programs directed towards preventing premature mortality. Recently, the State Epidemiologists have been trying to broaden their activities into these areas; however, the demands created by the acquired immunodeficiency syndrome (AIDS) will mostly likely slow this process. Based on the overall findings and collective experience, it was concluded that State health departments have too few epidemiologists to address the wide variety of important public health problems facing our communities. It was proposed that each State health department have at least four epidemiologists (including one or more physician epidemiologists) and at least one master's level biostatistician and that the epidemiologists-per-population ratio not be less than 1 per million.

Using a national sample of hospital discharges, we found identical seasonal patterns for spontaneous abortions and conceptions but no significant seasonal variation in the rate of spontaneous abortions per 1,000 conceptions. The differences between our findings and those of previous investigators of spontaneous abortion may reflect our more comprehensive definition of spontaneous abortion, our more complete estimate of the monthly number of conceptions, and our more rigorous statistical analysis. The periodic regression analysis (PRA) reported in our study may be useful in other studies that monitor short-term trends.

At hospitals in three cities where public funding for legal abortions had been restricted, we reviewed the records of women with complications of all types of abortions. We compared the number of complications in the year before funding restriction with the number in the following year, during restriction. For complications of illegal and spontaneous abortions, we found no significant change in either the number or proportion of publicly funded hospitalizations. For complications of legal abortions, we found a decrease in both the number and proportion of publicly funded hospitalizations. For poor women, it appears that restriction of public funding for legal abortions has not markedly increased the number of illegal abortions, but has reduced the number of legal abortions, especially those at later gestational ages, which would have cost more and been at greater risk of complications.
