ABSTRACT

This study measured the amount of time women spent obtaining prenatal care, and related that time spent to satisfaction with care. Women with Medicaid coverage (n = 364) were interviewed about several parameters related to their most recent prenatal visit: (1) how long it took them to get to the visit; (2) how long they waited upon arrival; and (3) how much time they spent with practitioners during the visit. Women were asked questions regarding satisfaction with the most recent visit, and with their care in general. They received care from four sources: private practitioners, community health centres (CHCs), hospital clinics and health department clinics. Women's satisfaction with care decreased as time spent with practitioners decreased, relative to time spent travelling and waiting. Those obtaining care from CHCs were more likely to have shorter waiting times and longer visit times than women obtaining care from other sources. Women spent approximately 3 h during pregnancy in face-to-face contact with practitioners. Satisfaction with care is closely associated with women's relative time investment in obtaining care. Both satisfaction and time investment parameters vary widely by source of prenatal care.

ABSTRACT

OBJECTIVES: To compare language development in infants and young children with human immunodeficiency virus (HIV) infection to language development in children who had been exposed to HIV but were uninfected, and (among subjects with HIV infection) to compare language development with cognitive and neurologic status. DESIGN: Prospective evaluation of language development in infected and in exposed but uninfected infants and young children. SETTING: Pediatric Infectious Disease Clinic, State University of New York-Health Science Center at Syracuse. SUBJECTS: Nine infants and young children infected with HIV and 69 seropositive but uninfected infants and children, age 6 weeks to 45 months. RESULTS: Mean Early Language Milestone Scale, 2nd edition (ELM-2) Global Language scores were significantly lower for subjects with HIV infection, compared with uninfected subjects (89.3 vs 96.2, Mann-Whitney U test). The proportion of subjects scoring >2 SD below the mean on the ELM-2 on at least one occasion also was significantly greater for subjects with HIV infection, compared with uninfected subjects (4 of 9 infected subjects, but only 5 of 69 uninfected subjects; Fisher's exact test). Seven of the 9 subjects with HIV infection manifested deterioration of language function. Four manifested unremitting deterioration; only 1 of these 4 demonstrated unequivocal abnormality on neurologic examination. Three subjects with HIV infection and language deterioration showed improvement in language almost immediately after the initiation of antiretroviral drug treatment. Magnetic resonance imaging or computed tomography of the brain were performed in 6 of 7 infected subjects with language deterioration, and findings were normal in all 6. ELM-2 Global Language scaled scores showed good agreement with the Bayley Mental Developmental Index or the McCarthy Global Cognitive Index (r = 0. 70). Language deterioration, or improvement in language after initiation of drug therapy, coincided with or preceded changes in global cognitive function, at times by intervals of up to 12 months. CONCLUSIONS: Language deterioration occurs commonly in infants and young children with HIV infection, is seen frequently in the absence of abnormalities on neurologic examination or central nervous system imaging, and may precede evidence of deterioration in global cognitive ability. Periodic assessment of language development should be added to the developmental monitoring of infants and young children with HIV infection as a means of monitoring disease progression and the efficacy of drug treatment.

ABSTRACT

OBJECTIVE: To evaluate the prognostic significance of the Bethesda system's cytologic categories in patients with endometrial malignancy. METHODS: Patients with biopsy or hysterectomy-proven endometrial malignancy and a Papanicolaou smear result reported using the Bethesda system within 1 year of diagnosis were identified through retrospective review of our computerized database. RESULTS: After introduction of the Bethesda system in our laboratory on November 1, 1992, until January 1, 1997, 112 eligible patients were identified (108 with carcinomas and four with carcinosarcomas). Patients with cytologic diagnoses of malignancy (n = 17) were significantly more likely to have International Federation of Gynecology and Obstetrics (FIGO) grade 3 tumors and high-risk histology (serous, clear cell, and adenosquamous carcinoma and carcinosarcoma) than those with atypical glandular cells of uncertain significance (n = 33) or those with cytology not suspicious for malignancy (n = 63). Patients with malignant smears were also significantly more likely to have cervical extension, malignant peritoneal cytology, and FIGO stage II, III, or IV than those with atypical glandular cells of uncertain significance or those with cytology not suspicious for malignancy. CONCLUSION: Papanicolaou smears obtained within 1 year of histologic diagnosis of endometrial malignancy and interpreted using the Bethesda system were suspicious for (atypical glandular cells of uncertain significance) or diagnostic of malignancy in nearly half of all cases (29 and 15%, respectively). Patients having malignant glandular cells were more likely to have poor prognostic pathologic findings.

ABSTRACT

Gestational diabetes mellitus (GDM) is the most common medical complication of pregnancy. Women with GDM are at elevated for numerous maternal health complications, and their infants are at elevated risk for death and morbidity. Management of GDM has traditionally been through diet and close monitoring of glucose levels, with initiation of insulin therapy when diet alone fails to maintain euglycemia. Recently, however, it has been suggested that alternative treatment modalities, such as exercise, may overcome a peripheral resistance to insulin, thus preventing GDM or controlling hyperglycemia in women with GDM. In this study, conducted from October 1995 to July 1996, the authors used a population-based birth registry to determine whether exercise has a preventive role in the development of GDM in women living in central New York State. They used contingency tables and chi-square statistics to examine bivariate differences among maternal and demographic variables and the occurrence of GDM. When stratified by prepregnancy body mass index category, exercise was associated with reduced rates of GDM only among women with a body mass index greater than 33 (odds ratio = 1.9, 95% confidence interval 1.2-3.1). The effect of exercise in obese women was further complicated by insurance status. When the data were stratified by insurance status, it appeared that women of higher socioeconomic status who were obese and did not exercise were at a significantly elevated risk of GDM compared with their counterparts of lower socioeconomic status. The results of this study suggest that for some women exercise may play a role in reducing the risk that they will develop GDM during pregnancy.

ABSTRACT

OBJECTIVES: Histologic findings in biopsy specimens obtained from patients with atypical glandular cells of uncertain significance were studied to define the utility and limitations of this category. STUDY DESIGN: Computerized records over a 3-year period were retrospectively analyzed. The most significant histologic diagnosis from all biopsy specimens submitted was compared with the subcategory of the first Papanicolaou smear obtained showing atypical glandular cells of uncertain significance. RESULTS: Biopsy results were available for 531 of 1117 patients with atypical glandular cells of uncertain significance (48%). Biopsy-proved preinvasive (83%) or invasive (17%) lesions were present in 191 patients (36%). Eighty-nine percent of the preinvasive lesions were squamous, whereas 97% of the invasive lesions were glandular. Glandular lesions were more likely to be invasive, whereas squamous lesions were more likely to be preinvasive (p < 0.001). Twenty-eight patients had endometrial carcinoma, which represents 88% of all invasive carcinomas detected. CONCLUSIONS: Almost three fourths of patients with atypical glandular cells of uncertain significance and with lesions have squamous lesions, not glandular as suggested by the name of the category. Unlike patients with atypical squamous cells of uncertain significance, patients with atypical glandular cells of uncertain significance have a significant risk of malignant lesions, which are nearly all glandular and predominantly arise from the endometrium.

ABSTRACT

OBJECTIVE: To establish the frequency of the atypical glandular cells of uncertain significance (AGCUS) category, and its subcategories, as defined by the Bethesda System (TBS). METHODS: Our computerized records of cervical/vaginal cytology specimens submitted from January 1, 1993, through December 31, 1995, were retrospectively reviewed for specimens diagnosed as AGCUS. When appropriate, our subcategory of "AGCUS favor premalignant/malignant lesion" was further qualified as "favor endocervical adenocarcinoma in situ" or "suspicious for endometrial carcinoma." The number of specimens and patients diagnosed for each subcategory were grouped by calendar year. Differences in frequency between time periods were tested for statistical significance using chi 2 analysis. RESULTS: AGCUS was diagnosed in 1181 of 177,715 submitted specimens (0.66%). The frequency of subcategories was as follows: "favor reactive" (65%), "unable to further classify" (30%), "favor premalignant/malignant" (2.9%), "suspicious for endometrial carcinoma" (1.9%), and "favor endocervical adenocarcinoma in situ" (0.4%). From 1993 to 1995 there was an increase in the rate of diagnosis of AGCUS (0.55 to 0.73%; P < 0.001) and a decrease in the percentage of specimens with AGCUS subclassified as "favor premalignant/malignant" (6.2 to 0.5%; P < 0.001). Other subcategories showed no significant change in frequency over this time period. The rate of biopsy-proven preinvasive or invasive lesions in AGCUS patients also showed no significant change from year to year over this time period. CONCLUSION: The AGCUS diagnosis can be anticipated at a low but consistent rate from a cytology laboratory using TBS. Any comparison of laboratories should take into consideration the change in reporting frequencies that occurs as part of the "learning curve" following introduction of TBS reporting. Uniform diagnostic criteria and additional reports with large numbers of cytologic specimens will be needed to establish the expected frequency of AGCUS and its subcategories.

ABSTRACT

OBJECTIVES: This study assessed the effect of unintended pregnancy on breast-feeding behavior. METHODS: All women delivering a live birth between January 1, 1995, and July 31, 1996 (n = 33,735), in the 15-county central New York region were asked whether they had intended to become pregnant and their breast-feeding plans. RESULTS: Women with mistimed pregnancies, and pregnancies that were not wanted were significantly less likely to breast-feed than were women whose pregnancies were planned. After adjustment for confounding variables and contraindications for breast-feeding, the odds ratios of not breast-feeding remained significant. CONCLUSIONS: Promoting breast-feeding among women with unintended pregnancies is important to improve health status.

ABSTRACT

OBJECTIVES: The authors examine 58,441 obstetric deliveries in New York State outside New York City to test for the existence of defensive medicine in obstetrics. METHODS: The data consist of merged vital statistics and hospital discharge records from the New York State Department of Health, together with other merged variables. Physician fear of malpractice is proxied by cumulative obstetric malpractice suits by county for 1975 through 1986. A generalized probit analysis is used. RESULTS: Malpractice exposure is shown to influence slightly the use of the electronic fetal monitor (EFM), a major diagnostic tool. Use of the EFM is shown to influence the diagnosis of fetal distress; fear of malpractice influences this diagnosis both directly and through the EFM. The diagnosis of fetal distress significantly affects the choice of cesarean section (c-section) as a method of delivery; hence, fear of malpractice influences the choice of a c-section both directly and through the diagnosis of fetal distress. Failure to include indirect effects via diagnostic procedures and diagnosis would result in an underestimate of the effect of fear of malpractice. Of an overall c-section rate of 27.6% in the data set, fear of malpractice accounts for an estimated 6.6 percentage points, of which 4.4 percentage points reflect a direct effect, and the remaining 2.2 percentage points reflect the effect of malpractice exposure on the use of the EFM and, directly and indirectly, the diagnosis of fetal distress. CONCLUSIONS: The results appear to confirm the existence of defensive medicine in obstetrics. Whether this is a desirable or undesirable effect remains ambiguous, but it is costly.

ABSTRACT

OBJECTIVE: To explore the relationship between pre-pregnancy obesity and the risk for cesarean delivery. METHODS: The population studied included 20,130 women with live births after 20 weeks' gestation in central New York state between June 1, 1994, and May 31, 1995. Women who were obese before pregnancy were compared with nonobese women with regard to mode of delivery. Obesity was defined as body mass index (BMI) greater than 29. Separate analyses were conducted on the entire sample and on a subset of women with singleton pregnancies and no prior cesarean deliveries, as an estimate of the risk of primary cesarean delivery in obese women. Statistical analyses included chi 2 test, crude odds ratio (OR) with 95% confidence interval (CI), and adjusted OR with 95% CI, using logistic regression to control for confounding variables. RESULTS: The adjusted OR was 1.64 (95% CI 1.46, 1.83) for obese women with singleton pregnancies and no prior cesarean deliveries to undergo cesarean delivery. The adjusted OR was 1.66 (95% CI 1.51, 1.82) for obese women in the entire sample to undergo cesarean delivery. In addition, increasing BMI was associated with increased risk for cesarean delivery. CONCLUSION: Compared with nonobese women, women who are obese before pregnancy are at increased risk for cesarean delivery. Preconceptional counseling regarding dietary and life-style modifications may alter this pattern.

ABSTRACT

We evaluated the cost impact of implementing a perinatal data system (PDS) on birth certificate (BC) processing and perinatal quality improvement (QI) reporting. Relevant staff in all birthing hospitals in the 15-county Central New York region (N = 23) were interviewed at baseline prior to implementation of the PDS and one year after implementation of the PDS to ascertain the time and costs of BC processing and of QI report generation. The average time and cost to collect and complete BCs did not change significantly from baseline to year 1. The time and costs to complete QI reports decreased significantly by 70 percent during this same period. Hospitals fully using the PDS for QI reporting purposes took, on average, six percent of the time it took other hospitals to generate comparable QI reports. The PDS significantly reduced the time and cost of generating perinatal reports from a consolidated database over what hospitals had done previously. Given the richness of the reports and the efficiency with which they are produced, hospitals are encouraged to adopt electronic means of BC processing and accessing these data for QI reporting purposes.

ABSTRACT

OBJECTIVE: This study tests two hypotheses: that a given delivery is less likely to be by cesarean section (c-section) in an HMO (closed-panel health maintenance organization) or IPA (independent practice association), than in other settings; and that where HMO and IPA penetration is high, the probability of a c-section will be reduced for all deliveries, whether in prepaid groups or not. DATA SOURCES AND STUDY SETTING: A data set consisting of 104,595 obstetric deliveries in New York state in 1986 is analyzed. STUDY DESIGN: A series of probit regressions is estimated, in which the dependent variable is either the probability that a given delivery is by c-section, or that a given delivery will result in a c-section for dystocia or fetal distress. DATA COLLECTION/EXTRACTION METHODS: The Live Birth File is linked with SPARCS hospital discharge data and other variables. PRINCIPAL FINDINGS: HMO setting reduces the probability of a cesarean section by 2.5 to 3.0 percentage points. However, this result is likely to be partly an artifact of offsetting diagnostic labeling and of choice of method of delivery, given diagnosis; a better estimate of the effect of HMO setting is -1.3 percentage points. IPA setting appears to affect the probability of a cesarean section even less, perhaps not at all. And HMO and IPA penetration in a region, as measured by HMO and IPA deliveries, respectively, as a percent of all deliveries, has relatively large depressing effects on the probability of a cesarean section. CONCLUSIONS: Ceteris paribus, the probability of a c-section is lower for an HMO delivery than for a fee-for-service delivery; however, HMO effects are smaller than previously reported in the literature for other types of inpatient care. For IPA deliveries, the effects are still smaller, perhaps nil. However, HMO and IPA penetration, possibly measuring the degree of competition in obstetrics markets, have important effects on c-section rates, not only in HMO/IPA settings, but throughout an area. These results appear to have important implications for public policy.

ABSTRACT

This study examines 65,784 obstetric deliveries occurring in 1986 in New York State, attended by 1740 different physicians. Cesarean section rates, and rates of reporting of dystocia and fetal distress, are calculated by physicians' year of graduation from medical school, U.S. or foreign medical graduate (FMG), physician sex, board certification, and professorial appointment. Probit regressions are estimated, in which the dependent variable is whether an individual delivery is vaginal or cesarean section. Crude cesarean section rates, cross-tabulations, and probit regressions all show physician characteristics to influence cesarean section rates significantly. FMGs are significantly more likely to deliver by cesarean section, both overall and when all other relevant factors are controlled for. Cesarean section rates by FMGs vary somewhat according to U.S. vs non-U.S. birthplace, and country or area where educated. Unlike others, the authors fail to find more recently graduated physicians to have higher cesarean section rates. Indeed, their rates for dystocia are significantly lower, when other factors are controlled for. Women physicians have a slightly lower cesarean section rate overall when other factors are controlled for, but a higher rate for dystocia. Board certified obstetricians have significantly higher, and physicians with professorial appointments lower cesarean section rates, though the direction of causation is not always clear. The authors conclude that the effect of physician characteristics on clinical behavior is a fruitful line of inquiry, and that in particular the results pertaining to FMGs warrant further investigation.

ABSTRACT

This study describes a research project involving economic and noneconomic aspects of the cesarean decision. The study was based on a 1986 data set dealing with 68,847 obstetric deliveries in New York State excluding New York City, and had the largest number of variables known to have been assembled to analyze the cesarean decision. The authors estimated a probit multiple regression in which the dependent variable was the method of delivery. The results diverge from widely held beliefs and research findings in some areas, and are of considerable interest in other areas. Contrary to other findings, the authors did not find a relationship between date of graduation from medical school and the probability of a cesarean section. More importantly, the authors failed to find much support for the idea that obstetricians perform cesareans to enrich themselves from the additional free income. However, our findings are consistent with the idea that obstetricians occasionally perform cesarean sections to manage their time, which does represent a form of economic self-interest. The study developed a proxy measure for fear of malpractice and found a negative relationship between fear of malpractice and cesarean section use. Finally, county cesarean rate and adjusted hospital cesarean section rate strongly and significantly influenced the probability that a given delivery is performed by cesarean section.

ABSTRACT

Approximately one-third of the Irish population receive all medical care services free. GPs (general practitioners) treat both public and private patients, and are remunerated on a fee-for-service basis by the state for public patients, and by the patient, at a higher rate, for private patients. In 1981, the first author conducted a national survey of Irish medical care utilization, asking whether patients' most recent GP visits resulted in a return visit being arranged. This measure of self-referral by GPs is significantly and strongly associated with the ratio of GPs to population, and negatively with the ratio to population of persons eligible for free services, and with area per capita income. All three results are as hypothesized from a theoretical model, and point to significant self-interested physician-induced demand by Irish GPs.
