Costs and charges associated with three alternative techniques of hysterectomy.

BACKGROUND: Many hysterectomies are now performed by a laparoscopically assisted vaginal technique. This procedure is controversial, partly because of concern about cost. We studied hospital charges and costs for the procedure as compared with those for total abdominal hysterectomy and total vaginal hysterectomy in clinically similar groups of patients. METHODS: From hospital-discharge data and patients' charts, we identified hysterectomies performed in 1993 and 1994 by 96 surgeons at a community teaching hospital to treat benign conditions. The patients were grouped according to the surgical procedures performed in conjunction with the hysterectomy. Data on hospital charges and cost-to-charge ratios for 64 hospital cost centers were used to assess charges and costs for specific resources, as well as for the hospitalization overall. RESULTS: Of 1049 patients studied, 26 percent underwent laparoscopically assisted vaginal hysterectomy, 54 percent underwent abdominal hysterectomy, and 20 percent underwent vaginal hysterectomy. The average hospital stays were 2.6, 3.9, and 2.9 days, respectively, and the mean total charges (facility charges plus professional fees) for the hospitalizations were $6,116, $5,084, and $4,221 (P<0.001 for the comparison of the laparoscopic technique with both other techniques). The mean facility costs were $4,914, $3,954, and $3,116, respectively (P<0.001 for the same comparison), with similar findings in all subgroups. The higher charges and costs for laparoscopically assisted vaginal hysterectomy were due to higher supply costs, particularly when disposable supplies were used, and to longer operating-room time. CONCLUSIONS: Despite shorter hospital stays, in-hospital charges and costs for laparoscopically assisted vaginal hysterectomy are higher than for either alternative procedure, because of the disposable supplies that are typically used and the longer operating-room time.

Economic savings and costs of periodic mammographic screening in the workplace.

This article discusses the costs and benefits of mammographic screening in the workplace. The cost of mammography itself and of diagnostic work-up are two of the largest costs involved. Therefore, the most efficient approach to providing mammography depends on the number of employees receiving mammography; and the diagnostic accuracy of mammography and underlying incidence of breast cancer in the screened population strongly influence the number of suspicious mammograms that are not associated with breast cancer. The health benefit of mammographic screening is due to reduced mortality and morbidity through early detection and more effective treatment, which may also result in economic savings if early-stage cancer is less expensive to treat. However, the total lifetime cost of treating early-stage cancer may be greater than treating late-stage cancer because of improved survival of early-stage patients. Thus, although periodic mammographic screening is not likely to result in overall economic savings, in many populations of working-age women, especially those with identifiable risk factors, screening is cost-effective because the expenditure required to save a year of life through early detection of breast cancer is low compared to other types of health services for which employers commonly pay.

Vaginal birth after cesarean. Physicians' perceptions and practice.

OBJECTIVE: To determine physician's perceptions about vaginal birth after cesarean section and compare them to the physicians' actual practice experience. STUDY DESIGN: Physicians responded to a questionnaire on their perceptions of vaginal birth after cesarean section. Between July 1, 1991, and June 30, 1992, all attempts at vaginal birth after cesarean section were reviewed. All cesarean deliveries were also reviewed to determine which repeat cesarean sections could have been avoided. RESULTS: One hundred twenty-four patients attempted vaginal birth after cesarean section, and 95 (76.6%) were successful. Physician perceptions revealed a success rate of 73.6%. Those patients whose labor was induced in their attempt at vaginal birth after cesarean section were less successful (41.9%) than those who did not require induction (88.2%) (P < .001). Upon review, 47% of patients who underwent elective repeat cesarean section did not have a contraindication to a trial of labor. CONCLUSION: Physicians had an accurate perception of the success of vaginal birth after cesarean section in their practices. Vaginal birth after cesarean section success rates were consistent with those reported in the literature. Despite a high attempt rate (72.5%) among those eligible for vaginal birth after cesarean section, almost half the patients undergoing a repeat elective cesarean section did not have a contraindication to a trial of labor.

Adolescent development and transitions to motherhood.

OBJECTIVE: To use both qualitative and quantitative methods to examine the experience of motherhood during adolescence and to evaluate developmental influences on the concept of maternal role. DESIGN: (1) A grounded theory approach was initially used to generate a hypothesis. Focus groups and individual interviews were analyzed for concept and theme. (2) A quantitative method using correlational analysis was used to test the hypothesis generated by qualitative study. A structured interview using five specific, scored questions about self and about motherhood was used to examine the relationship between developmental complexity of responses to questions about self and questions about motherhood. SETTING AND PARTICIPANTS: The qualitative study involved group and individual interviews with 42 teenage mothers. The quantitative study involved individual interviews with 25 mothers, ages 14 to 18 years, at an innercity clinic for young parents and their infants. Race and ethnicity were heterogeneous, and 100% received Aid to Families With Dependent Children. RESULTS: The major hypothesis generated from the qualitative analysis was that an adolescent mother's conceptualization of her maternal role is related to her own psychosocial and cognitive development. The quantitative study revealed a strong correlation between the developmental complexity of responses to questions about self and the complexity of responses to questions about motherhood (r2 = .81). CONCLUSION: The experience of motherhood and the conceptualization of the maternal role in adolescence is related to young mothers' psychosocial cognitive development.

Developmental outcome as a function of the goodness of fit between the infant's cry characteristics and the mother's perception of her infant's cry.

OBJECTIVE: To determine whether the "goodness of fit" between infant cry characteristics and the mother's perception of the cry is related to developmental outcome at 18 months of age. DESIGN: This was a prospective, longitudinal study from birth to 18 months performed in a blinded manner. SETTING: The study was conducted in a maternity hospital, including normal and special care nurseries and a laboratory for developmental follow-up. PATIENTS: The 121 term and preterm infants and their mothers were selected to meet medical criteria. MEASUREMENT: Acoustic analysis of 1-month infant cry and the mother's perception of the same cry was used to divide subjects into four groups representing matches and mismatches between infant cry characteristics and maternal cry perception. Primary outcome measures of cognitive, language, motor, and neurologic outcome were administered at 18 months. Caretaking environment measures were also recorded. RESULTS: Statistically significant (P < .05) findings showed that matched groups scored higher on measures of language and cognitive performance than infants in the mismatch groups, with a particular advantage for infants in the matched group in which mothers accurately perceived the higher-pitched cries of their infants. There were no differences between the groups in biologic or sociodemographic factors. Group differences were observed in social support and maternal self-esteem. CONCLUSIONS: Matches and mismatches between infant cry characteristics at 1 month and the mother's perception of the cry are related to cognitive and language outcome at 18 months in term and preterm infants. This relation is probably due to transactional processes in which developmental outcome is affected by the clarity of the infants' signals and by the ability of the mother to accurately perceive her infant's signals. The mother's ability to read her infant's cues may be affected by factors such as social support and self-esteem.

The use of a generic, patient-based health assessment (SF-36) for evaluation of patients with anterior cruciate ligament injuries.

The MOS 36-item short-form health survey is a generic, patient-based health assessment tool. It has been used to assess functional outcome for many medical conditions, both acute and chronic. The use of this survey in evaluating the effects of treatment of any specific disease or injury allows comparison of treatments across a broad spectrum of disease categories. The purpose of this study was to see if this assessment tool could 1) be used to identify those patients requiring anterior cruciate ligament reconstruction, 2) detect changes in the patients with treatment over time, and 3) correlate with the commonly used knee assessment scales. The short-form health survey could not identify those patients requiring anterior cruciate ligament reconstructive surgery. However, it did show important and significant changes with treatment (surgical and nonsurgical) over time. There was a significant correlation between the short-form health survey and the Lysholm and International Knee Documentation Committee scores during this study. The addition of the MOS 36-item short-form health survey to our traditional knee ligament evaluation tools is encouraged. Its use will permit the orthopaedic community to demonstrate the value of our treatment of anterior cruciate ligament injuries to health care planners and generalist physicians.
