Obstetric care,Medicaid, and family physicians. How policy changes affect physicians' attitudes.

Recent expansion of Medicaid eligibility for pregnant women and increased reimbursement to physicians who provide perinatal services were designed to improve access to care. Family physicians provide a relatively high proportion of care to pregnant women on Medicaid, especially in rural areas. We surveyed all family physicians who provide obstetric services in 26 northern California counties regarding these changes and perceived barriers to providing obstetric care to women on Medicaid. Of surveyed physicians who limited the number of their Medicaid obstetric patients, 58% stated that recent Medicaid policy changes had increased their willingness to accept new Medicaid obstetric patients. Despite these policy changes, administrative issues and poor reimbursement were cited as the two most notable barriers to providing obstetric care to women on Medicaid. Fear of being sued by Medicaid patients is still seen as a barrier by physicians who have recently discontinued practicing obstetrics and by those who continue to care for a large number of Medicaid obstetric patients.     

The safety of obstetric services in small communities in northern Ontario.

The safety of the obstetric care system in the small hospitals of northern Ontario was assessed by analysing the outcomes of all obstetric cases over a 2-year period. Information was retrieved by place of residence rather than hospital of delivery so that the overall perinatal system, including the referral patterns, would be assessed. There was little difference in perinatal loss rate (stillbirths and neonatal deaths up to 28 days per 1000 births) for residents of areas served by different levels of obstetric care. Areas served by units where cesarean sections are done regularly but which do not have specialists in obstetrics or pediatrics had a perinatal loss rate of 10.43, whereas areas served by units staffed with two or more specialists in both obstetrics and pediatrics and handling more than 1000 deliveries per year had a perinatal loss rate of 12.13. Although many of the smaller hospitals did not have the minimum capabilities suggested for obstetric units relatively safe care was being provided. These results do not support the need for further centralization of obstetric services in northern Ontario.     

Evaluating perinatal mortality rates: effects of referral and case mix.

OBJECTIVE--To evaluate perinatal mortality rates as a method of auditing obstetric and neonatal care after account had been taken of transfer between hospitals during pregnancy and case mix. DESIGN--Case-control study of perinatal deaths. SETTING--Leicestershire health district. SUBJECTS--1179 singleton perinatal deaths and their selected live born controls among 114,362 singleton births to women whose place of residence was Leicestershire during 1978-87. MAIN OUTCOME MEASURE--Crude perinatal mortality rates and rates adjusted for case mix. RESULTS--An estimated 11,701 of the 28,750 women booked for delivery in general practitioner maternity units were transferred to consultant units during their pregnancy. These 11,701 women had a high perinatal mortality rate (16.8/1000 deliveries). Perinatal mortality rates by place of booking showed little difference between general practitioner units (8.8/1000) and consultant units (9.3-11.7/1000). Perinatal mortality rates by place of delivery, however, showed substantial differences between general practitioner units (3.3/1000) and consultant units (9.4-12.6/1000) because of the selective referral of high risk women from general practitioner units to consultant units. Adjustment for risk factors made little difference to the rates except when the subset of deaths due to immaturity was adjusted for birth weight. CONCLUSION--Perinatal mortality rates should be adjusted for case mix and referral patterns to get a meaningful result. Even when this is done it is difficult to compare the effectiveness of hospital units with perinatal mortality rates because of the increasingly small subset of perinatal deaths that are amenable to medical intervention.     

Planned and unplanned deliveries at home: implications of a changing ratio.

The observation that perinatal mortality among babies delivered at home has tended to increase beyond that among babies delivered in consultant obstetric units has caused alarm and prompted recommendations that delivery at home should be further phased out. With data derived from the Cardiff Births Survey the possibility was investigated that this trend might reflect a changing ratio of planned to unplanned domiciliary births. At the beginning of the 1970s deliveries at home that were planned to be so outnumbered those that were not by nearly five to one. By 1979 unplanned deliveries at home outnumbered planned deliveries. The characteristics of the mothers, the health care they received, and the outcome of delivery differed strikingly between planned and unplanned deliveries at home. It is concluded, firstly, that every year the maternity services must try to meet the various needs of about 2000 women in England and Wales who give birth at home without planning to do so; and, secondly, that the heterogeneity of births at home and in hospital will continue to obstruct the search for unbiased estimates of the risks attributable to delivery in specialist obstetric units, general practitioner units, and at home.     

Short term outcome in babies refused perinatal intensive care.

OBJECTIVE--To compare the mortality in babies refused admission to a regional perinatal centre with that in babies accepted for intensive care in the centre. DESIGN--Retrospective study with group comparison. SETTING--Based at the Royal Maternity Hospital, Belfast, with follow up of patients in all obstetric units in Northern Ireland. PATIENTS--Requests for transfer of 675 babies to the regional perinatal centre (prenatally and postnatally) were made from hospitals in Northern Ireland between January 1984 and December 1986. In all, 343 babies were refused admission to the centre, and complete data were available for 332 of them. These babies were either admitted to other neonatal intensive care units (261 babies) or remained in hospitals with only special care cots (71 babies). MAIN OUTCOME MEASURE--Short term mortality. RESULTS--Seventy of the 332 babies refused admission to the centre died compared with 51 of the 333 who were admitted. Multivariate analysis based on a logistic model showed a non-significant increase in mortality among babies treated in other intensive care units compared with babies treated in the centre (relative odds 1.2; 95% confidence interval 0.7 to 1.9). The increase in mortality in babies who remained in a special care baby unit, however, was significant (3.5; 1.7 to 7.0). This increase was particularly significant in babies born at less than or equal to 32 weeks'' gestation and who weighed less than 1500 g (8.4; 2.5 to 28.1). CONCLUSIONS--The results of the study confirm the benefits of neonatal intensive care and its particular value in improving survival in babies of low birth weight. As the babies were refused admission to the regional perinatal centre because intensive care cots were not available this deficiency should be corrected.     

Specialized perinatal care: impact on perinatal mortality.

A neonatal intensive care unit was established at one hospital in 1972 when the neonatal mortality was 7.6 and the perinatal mortality 20.9 per 1000 deliveries. In 1973, with full operation of that unit and partial introduction of a high-risk pregnancy unit for fetal monitoring, the rates decreased to 6.4 and 14.9, respectively. With full operation of both units the rates decreased further, to 3.4 and 9.0 in 1974 and 3.8 and 8.9 in 1975. The frequency of cesarean section was 10.1% in 1972-73 and 11.6% in 1974-75. It is concluded that the centralization of obstetric and neonatal care, together with the development of qualified medical and nursing teams, had a major impact in reducing perinatal mortality, and that the frequency of cesarean section was not affected by the introduction of fetal monitoring, although the indications for this precedure became more specific.     

National census of availability of neonatal intensive care. British Association for Perinatal Medicine

ObjectiveTo determine whether availability of neonatal intensive care cots is a problem in any or all parts of the United Kingdom.DesignThree month census from 1 April to 30 June 1999 comprising simple data sheets on transfers out of tertiary units.SettingThe 37 largest high risk perinatal centres in the United Kingdom.ParticipantsOne obstetric specialist and one neonatal specialist in each centre.ResultsAll units provided data. The number of intensive care cots in each unit was between five and 16. During the three months 309 transfers occurred (equivalent to 1236 per year), of which 264 were in utero and 45 postnatal. Sixty five in utero transfers involved multiple births, hence the census related to 382 babies (1528 per year). There was considerable regional variation. The reason for transfer in most cases was “lack of neonatal beds”.ConclusionsCurrently most major perinatal centres in the United Kingdom are regularly unable to meet in-house demand; this has implications for the service as a whole. The NHS has set no standards to help health authorities and primary care groups develop services relating to this specialty; such a step may well be an appropriate lever for change.     

A Survey of Newborn Intensive Care Centers in California

Newborn intensive care has come of age in California. Twenty-one newborn intensive care centers and 11 community level units are now approved by Crippled Children Services in California. In 1973 there were more than 6,863 patients admitted to the 20 centers surveyed, over half requiring transport from referring hospitals. This paper provides information on the distribution, admission and occupancy rates, length of stay, costs and admission diagnoses for these high risk infants.     

Place of the General Practitioner in the Obstetric Service

A survey of perinatal mortality in Northern Ireland has shown that despite a progressive fall in the proportion of deliveries at home the perinatal mortality rate in domiciliary practice has risen in recent years. Overall, however, the perinatal mortality rate for all deliveries compares well with English figures. It seems that as the proportion of deliveries in hospital and general-practitioner obstetric unit rises a hard core of high risk patients is left who insist on delivery at home. Three prerequisites for good general-practice obstetrics are careful selection of cases, intelligent antenatal care, and close co-operation between the general practitioner and the consultant.     

General practitioner obstetrics in Bradford.

The standard of obstetrics care by general practitioners in Bradford was assessed by reviewing the case records of all women who in 1988 were booked for delivery under their general practitioner but subsequently required transfer to consultant care. A total of 5885 women were delivered in Bradford during 1988. Of 1289 booked under their general practitioner, 637 required transfer to consultant care. In 259 cases transfer occurred during labour; only 37 of these women were visited by their general practitioner. Many of the problems that precipitated transfer were predictable and some were considered preventable: 263 of the women transferred were considered unsuitable for booking by general practitioners. The perinatal mortality among women booked under their general practitioner was 10.1/1000 and the stillbirth rate 7.8/1000. These figures are high and suggest a need for tighter controls over the qualifications and experience of doctors participating in a fully integrated system of obstetric care.     

Northern obstetrics: a 5-year review of delivery among Inuit women.

There are over 18,000 Inuit in the Northwest Territories. As a group they have the highest birth rate, the lowest cesarean section rate and one of the highest perinatal death rates in Canada. We reviewed the obstetric experience of 512 Inuit women who either gave birth at Stanton Yellowknife Hospital or were referred from Yellowknife and gave birth at a southern facility between January 1981 and December 1985. Our experience is consistent with that documented in earlier reviews, which concluded that Inuit women tend to have efficient uterine action, to endure labour well and to rarely have dystocia. During the periods covered by these reviews delivery was frequently in the settlements; now hospital delivery is the norm. Substantial improvements in perinatal outcome are evident, but there remains a considerable gap between the northern and southern experience. Those attempting further progress must recognize that the need for obstetric care away from the home community is not fully appreciated by Inuit women, their families or their communities.     

An audit of antenatal care: the value of the first antenatal visit.

A critical analysis of the events recorded at the first antenatal visits in a city where all pregnant women are seen by specialist obstetricians for booking for antenatal care and confinement showed that many women attended too late for optimal care. The selection of women for their risk of complications was not very effective, partly because of failure to take account of information that was available, but mainly because many obstetric complications cannot be predicted, except by classifying large proportions of pregnant women as high risk. Even with the greatest care, inappropriate bookings are made at the first visit, and reappraisal of booking for continuing care and confinement is necessary during pregnancy.     

Quality of obstetric care provided for Asian immigrants in Leicestershire.

Between 1976 and 1981 some 939 perinatal deaths occurred to women living in Leicestershire, of which 128 (14%) were to Asian women. The qualifications of the general practitioners, the gestation at which women start antenatal care, and perinatal death were used as structural, process, and outcome measures for evaluating the services provided to Asian immigrants within this population. Perinatal deaths were divided into four groups: congenital malformation, macerated stillbirth, asphyxia in labour, and immaturity. Asian mothers had one and a half times the risk of perinatal mortality when social class, parity, height, legitimacy, and the general practitioner''s qualifications were taken into account. Asian and non-Asian mothers with general practitioners who were not on the obstetric list had more than twice the risk of a perinatal death when a similar adjustment was made. Recommendations include priority allocation of community midwives to practitioners not on the obstetric list, the establishment of postgraduate courses for such doctors, and the continued evaluation of the effect of such proposals on perinatal mortality.     

Prognosis for infants born at 23 to 28 weeks' gestation.

The survival and neurodevelopmental outcome of 356 extremely preterm infants born at 23 to 28 weeks'' gestation were reported by week of gestation. Their corrected 1 year survival improved from 7% at 23 weeks to 75% at 28 weeks. The overall incidence of impairment was 19% and of major disability 12%. Boys had a significantly lower normal survival than girls. Multiple births had a significantly lower survival and higher incidence of impairment than singleton births. Predictions of outcome were made before delivery, after resuscitation, and at 1 week to aid the development of guidelines on when perinatal intensive care is justified, whether obstetric intervention for fetal reasons is warranted, and what initial and ongoing prognoses to give to parents. Intensive care for progressively smaller and more immature infants, many of whom were previously considered non-viable, needs to be carefully monitored by every perinatal centre.     

Impact of placental Plasmodium falciparum malaria on pregnancy and perinatal outcome in sub-Saharan Africa: II: effects of placental malaria on perinatal outcome; malaria and HIV

Placental malaria is recognized as a common complication of malaria in pregnancy in areas of stable transmission, and, as a consequence, serious health problems arise for the mother and especially her baby [1]. Although malaria in pregnancy is a major factor associated with adverse perinatal outcome, the link between malaria and perinatal morbidity/mortality is less clear in areas with stable endemic malaria where pregnant women have acquired immunity [2]. Histological examination of the placenta is a predictor of fetal morbidity, as well as being the most sensitive detector of maternal infection [3]. Adverse perinatal outcome has been described as an important indicator of poor quality of obstetric care and social development [4]. A variety of adverse perinatal outcomes associated with placental malaria have been described, including low birth weight, preterm delivery, intrauterine growth retardation, fetal anemia, congenital malaria, and fetal mortality. The most common clinical features in 80 percent of perinatal cases are fever, anemia, and splenomegaly [5]. Other signs and symptoms include hepatomegaly, jaundice, regurgitation, loose stools, poor feeding, and, occasionally, drowsiness, restlessness, and cyanosis also can be seen [5,6].A review of studies that investigated these poor fetal outcomes associated with placental malaria in sub-Saharan Africa is presented here.     

Options for Optimal Coverage of Free C-Section Services for Poor Mothers in Indian State of Gujarat: Location Allocation Analysis Using GIS

Background

Gujarat, a western state of India, has seen a steep rise in the proportion of institutional deliveries over the last decade. However, there has been a limited access to cesarean section (C-Section) deliveries for complicated obstetric cases especially for poor rural women. C-section is a lifesaving intervention that can prevent both maternal and perinatal mortality. Poor women bear a disproportionate burden of maternal mortality, and lack of access to C-section, especially for these women, is an important contributor for high maternal and perinatal mortality in resource limited settings. To improve access for this underserved population in the context of inadequate public provision of emergency obstetric services, the state government of Gujarat initiated a public private partnership program called “Chiranjeevi Yojana” (CY) in 2005 to increase the number of facilities providing free C-section services. This study aimed to analyze the current availability of these services in three districts of Gujarat and to identify the best locations for additional service centres to optimize access to free C-section services using Geographic Information System technology.

Methodology

Supply and demand for obstetric care were calculated using secondary data from sources such as Census and primary data from cross-sectional facility survey. The study is unique in using primary data from facilities, which was collected in 2012–13. Information on obstetric beds and functionality of facilities to calculate supply was collected using pretested questionnaire by trained researchers after obtaining written consent from the participating facilities. Census data of population and birth rates for the study districts was used for demand calculations. Location-allocation model of ArcGIS 10 was used for analyses.

Results

Currently, about 50 to 84% of populations in all three study districts have access to free C-section facilities within a 20km radius. The model suggests that about 80–96% of the population can be covered for free C-section services with addition of 4–6 centres in critical but underserved regions. It was also suggested that upgrading of public sector facilities with minimal investment can improve the services.

Conclusion

This study highlights utility of Geographic Information System technology for planning service centres to optimize access to vital lifesaving procedure such as C-section. Although the location allocation methodology has been available for decades, it has been used sparsely by public health professionals. This paper makes an important contribution to the literature for use of the method for planning in resource limited settings.     

Time trends in twin perinatal mortality in northern England, 1982-94. Northern Region Perinatal Mortality Survey Steering Group.

The dynamics of perinatal mortality rates (PNMR) and causes of death in twin pregnancies over 13 years in the Northern Region of the National Health Service in England is described. All twin perinatal deaths occurring between 1982-1994 were identified from the Northern Region Perinatal Mortality Survey. The twinning rate increased from 9.9 per 1000 maternities in 1982 to 12.0 in 1994. There was a total of 10,734 twin pregnancies and of these 421 resulted in 530 perinatal deaths. The perinatal mortality rate in twins significantly decreased over time (1982-87, 55.4 per 1000; 1988-94, 44.4 per 1000; P = 0.01). The PNMR was significantly higher for twins from like-sexed than from unlike-sexed pairs (53.5 and 34.4 per 1000 respectively, P < 0.001). Despite no improvement in birthweight distribution in the twin population, birthweight-specific perinatal mortality rates for both like and unlike-sexed twins decreased for each birthweight category in 1988-94 compared with 1982-87. Twins with very low birthweight (< 1500 g) comprised 69%, and preterm twins (< 37 completed weeks of gestation) 74.9% of all twin perinatal deaths. The major immediate cause of early neonatal death was pulmonary immaturity (63%); antepartum anoxia caused 76.9% of antenatal deaths. Unexplained preterm labour and intrauterine death were the leading obstetric factors underlying death in twins. Despite a decrease over the 13 years, the perinatal mortality rate in twins in the Northern Region remains high. Continued monitoring of trends in twinning and mortality rates is needed to inform health care planning.     

General practitioner obstetrics in the Northern region in 1983.

In late 1983 a four page questionnaire on general practitioner obstetrics was sent to a 50% random sample of general practitioners in the Northern region of England; 84% responded. Half of them said that they had access to general practitioner facilities for delivery, and half of these used them. A quarter of all respondents had provided intranatal care previously but had given it up, most of them during the late 1970s. Younger general practitioners were more highly qualified in obstetrics than older ones but did not do more intranatal work. Isolated general practitioner maternity units were much more likely to be used than those that were alongside consultant units or integrated with them. Ninety per cent of respondents provided antenatal care, 77% of these at special clinics and 88% with midwives in attendance. Teamwork, however, was not well developed. Increasing general practitioner participation in obstetric care seems feasible but depends heavily on more appropriate training and intranatal facilities being provided for general practitioners in association with specialist units.     

Shortfall of equipment for neonatal intensive care and the introduction of budget holding contracts.

As adequate allowance must be made for the costs of purchasing, maintaining, and updating equipment during the development of contracts the current standing of neonatal units with regard to available equipment was assessed. Data were collected as part of a one year prospective survey of the 17 perinatal units in the Trent region. Adequacy of provision of equipment for recognised intensive care cost was assessed using the recommendations of the British Paediatric Association and British Association of Perinatal Paediatrics. It was assumed that units without recognised intensive care cost had to be able to equip one cot to a standard of intensive care level 1 in the short term. Equipment more than 5 years old was considered likely to warrant replacement or major maintenance within the next two years. With these guidelines over 600,000 pounds would be required to provide sufficient equipment for all recognised level 1 intensive care cost and to allow units without funded cost to provide this level of care in the short term and to replace existing equipment more than 5 years old for these cost alone. This amount could be reduced by 25% by subdividing intensive care cost into levels 1 and 2, thereby reducing equipment requirements, but this would impair the units'' ability to perform level 1 care at funded provision, which has already been shown to need expansion. Neither figure takes account of equipment requirements for infants requiring special care. In addition, no allowance has been made for purchase or update of ultrasound scanners or blood gas analysers. If the government''s proposed reforms are to be implemented clinicians need to revise guidelines regarding essential equipment, and plans must be made to correct any existing shortfalls so that they do not become inherited financial liabilities for future budget holders.     

Perinatal mortality rates in isolated general practitioner maternity units.

OBJECTIVE--To determine the perinatal mortality rate among normally formed, singleton babies with birth weights greater than or equal to 2500 g in Bath health district based on the intended place of delivery at the time of onset of labour or at the time of diagnosis of intrauterine death. DESIGN--The numbers of live births and stillbirths were collected monthly returns from the maternity units concerned. Deaths of infants aged less than or equal to 1 week were collected in the same returns. The intended place of delivery was confirmed at the monthly perinatal mortality meeting, during which maternal and fetal factors were discussed. SETTING--A rural health district of 400,000 population where one third of all deliveries occurred in seven isolated general practitioner maternity units, 8% in the integrated general practitioner unit, and the remainder in the consultant unit. SUBJECTS--All babies of women whose deliveries were booked in the district before the onset of labour or the diagnosis of intrauterine death, excluding twins, babies with lethal congenital malformations, and those less than 2500 g. MAIN OUTCOME MEASURES--Outcome of all deliveries and parity of mothers. RESULTS--14,415 Deliveries were analysed. The perinatal mortality rate was 2.8/1000 births in the consultant unit (7950 deliveries), 4.8 in the isolated general practitioner units (5237 deliveries), and zero in the integrated general practitioner unit (1228 deliveries). Perinatal deaths attributable to asphyxia were more common in the isolated general practitioner units (1.5 per 1000) than the consultant unit (0.6 per 1000). The perinatal mortality rate among babies born to nulliparous women was 3.2/1000 births in the consultant unit and 5.7 in the isolated general practitioner units; for those born to multigravid women it was 2.4 and 4.2 respectively. CONCLUSIONS--The outcome of delivery was not influenced by parity. Both antenatal and intrapartum care were responsible for the higher perinatal mortality rate in the isolated general practitioner units. The integrated unit, which shared midwifery staff with the consultant unit, seemed to work well. Analysis by intended place of delivery at the time of onset of labour or diagnosis of intrauterine death suggested that the care given in isolated units needs to be improved, perhaps by better training of general practitioners and consultant supervision of antenatal care.
