Tort reform and the obstetric access crisis. The case of the WAMI states.

The states of Washington, Alaska, Montana, and Idaho (WAMI) have all had declines in the proportion of physicians offering obstetric services during the past few years, a decline precipitated by rising medical malpractice premiums. One response to the problem of rising liability premiums has been the passage of extensive tort reform legislation. We present the results of recent studies of physicians'' obstetric practices in the WAMI states and summarize the major changes in tort legislation and regulation that have occurred in these states. Most general and family physicians in the WAMI region no longer provide obstetric care; by contrast, more than 80% of the obstetrician-gynecologists in the WAMI states are still practicing obstetrics. Despite the fact that only a minority of family physicians are still active in obstetrics, most rural family physicians in all four states still deliver babies. Most physicians in all four states limit the amount of care they provide to those covered by Medicaid, which suggests that significant barriers to care exist for medically indigent persons. All four states have adopted significant tort reforms. Despite these changes in the legal environment, the cost of malpractice premiums and concerns over the likelihood of being sued continue to limit the number of physicians willing to provide obstetric care. Although it cannot be inferred from these data that tort reform has decreased the rate at which physicians give up obstetric practice, the evidence is compatible with such a conclusion.     

Factors influencing family physicians to continue providing obstetric care.

To determine the reasons some family physicians continue to practice obstetrics when most of their colleagues do not, we surveyed family physicians in 26 counties of northern California whose practices include obstetrics and those who have recently discontinued it. In all, 70% of family physicians practicing obstetrics cited enjoying it as a reason for continuing this practice. Over a third of family physicians practicing obstetrics thought that obstetric practice was a responsibility to the community. Only 1 in 6 reported obstetrics to be important in terms of financial implications. Despite this, family physicians practicing obstetrics had a mean gross income derived from obstetric practice of $30,000 above the cost of their total malpractice premium. In contrast, a comparison group of family physicians who had recently discontinued obstetrics cited malpractice insurance costs most frequently as the reason for discontinuing it. Nearly 40% of these physicians indicated that they would be willing to return to obstetrics if circumstances were to change substantially. The most frequently cited change necessary for these physicians to return to obstetrics was a reduction in malpractice insurance rates.     

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.     

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.     

There is an obstetrical dilemma: Misconceptions about the evolution of human childbirth and pelvic form

Compared to other primates, modern humans face high rates of maternal and neonatal morbidity and mortality during childbirth. Since the early 20th century, this “difficulty” of human parturition has prompted numerous evolutionary explanations, typically assuming antagonistic selective forces acting on maternal and fetal traits, which has been termed the “obstetrical dilemma.” Recently, there has been a growing tendency among some anthropologists to question the difficulty of human childbirth and its evolutionary origin in an antagonistic selective regime. Partly, this stems from the motivation to combat increasing pathologization and overmedicalization of childbirth in industrialized countries. Some authors have argued that there is no obstetrical dilemma at all, and that the difficulty of childbirth mainly results from modern lifestyles and inappropriate and patriarchal obstetric practices. The failure of some studies to identify biomechanical and metabolic constraints on pelvic dimensions is sometimes interpreted as empirical support for discarding an obstetrical dilemma. Here we explain why these points are important but do not invalidate evolutionary explanations of human childbirth. We present robust empirical evidence and solid evolutionary theory supporting an obstetrical dilemma, yet one that is much more complex than originally conceived in the 20th century. We argue that evolutionary research does not hinder appropriate midwifery and obstetric care, nor does it promote negative views of female bodies. Understanding the evolutionary entanglement of biological and sociocultural factors underlying human childbirth can help us to understand individual variation in the risk factors of obstructed labor, and thus can contribute to more individualized maternal care.     

High Risk Perinatal Care in California

Rates of perinatal mortality are still too high in California. Mortality and morbidity, particularly for high risk pregnancies, can be reduced by the use of modern technology in the hands of highly trained personnel. New goals for perinatal care have been published by the California Medical Association reflecting these changes. This kind of care is too costly to be developed in all the small obstetric units presently providing services in California. Consolidation of obstetric and neonatal units into fewer hospitals can make it economically possible for these units to meet present-day standards.     

Neurobehavioral sequelae of traumatic brain injury: evaluation and management

Traumatic brain injury (TBI) is a worldwide public health problem. Over the last several decades, improvements in acute care have resulted in higher survival rates. Unfortunately, the majority of survivors of moderate and severe TBI have chronic neurobehavioral sequelae, including cognitive deficits, changes in personality and increased rates of psychiatric illness. These neurobehavioral problems are understandable in the context of the typical profile of regional brain damage associated with trauma. This paper presents an overview of the neurobehavioral sequelae of TBI and outlines issues to consider in the evaluation and management of these challenges.     

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.     

Neonatal resuscitation in Canadian hospitals.

A survey of Canadian hospitals providing obstetric care was undertaken to assess preparation, protocols, training and staff availability for neonatal resuscitation. Of the 721 hospitals contacted 577 (80%) responded. The reported availability of written guidelines for resuscitation varied greatly, depending on hospital size and proximity to a tertiary care centre. Many hospitals, especially those with 300 births or fewer annually, reported that they depend on family physicians or nurses to start and to continue neonatal resuscitation. Approximately one third of the hospitals had written guidelines for summoning personnel for additional help, and one third used a list of maternal or fetal indications for the presence of a physician specifically for the care of the infant at birth. Of 200 hospitals 138 (69%) had to summon additional medical help from outside the institution, 60% at all times. A neonatal resuscitation team in which members'' roles were defined was established in 22% of the hospitals. Few hospitals held rehearsals for resuscitation. Nurses were permitted to perform intubation in 21 hospitals (4%), 7 of them in Alberta. National professional bodies should develop guidelines for training and skill maintenance, and hospitals should develop protocols for maintaining equipment and for neonatal resuscitation team activities, including regular practice. Training should be improved in family practice and obstetrics programs, and consideration should be given to training senior obstetric nurses and respiratory therapists in intubation of neonates.     

"Short report" staffing in practice: five years' experience of a consultant based service in obstetrics and neonatal paediatrics.

Recent government plans include the concept of a core of doctors of intermediate grade providing 24 hour emergency cover in hospital departments. Hinchingbrooke Hospital has, since its opening in 1983, been run on a two tier basis, with consultants and a part time senior registrar supported only by senior house officers in their first post, usually on general practice vocational training schemes. With a planned rate of around 2000 deliveries per year all high risk obstetric and neonatal paediatric procedures, including ventilation of very small babies, have been carried out within the hospital. A study of the first five complete years of operation of the obstetric and paediatric departments showed that the perinatal mortality rate was low (hospital rate 4.7/1000 in 9149 deliveries during 1984-8 v district rate 5.1/1000 during 1986-8), and patient satisfaction seemed to be high. In a separate prospective study of out of hours work performed by consultants in paediatrics (four weeks) and obstetrics (20 days) three consultants in paediatrics spent 71 hours working out of hours; for the obstetricians, of the 56 request for advice and 38 interventions, only five and six respectively occurred between midnight and 9 am. Although successful at this hospital, the two tier system would be expensive under the Royal College of Obstetricians'' guidelines of one consultant to a maximum of 500 deliveries. An equal mixture of two tier and three tier systems might be the best solution for patient care and training of junior doctors.     

Oxytocin and the augmentation of labor

At least a third of the women giving birth in the United States receive intravenous oxytocin for the induction and augmentation of labor. The problem of inactive or ineffective labor remains a major challenge for birth attendants, midwives, and physicians who practice obstetrics. Before the discovery of oxytocin, traditional approaches to augmentation ranged from magical and folk interventions to extensive bloodletting. Despite its wide use the effectiveness of oxytocin augmentation has not been well studied, and current research raises new questions about its effect on the brain.     

"Seeing the baby": pleasures and dilemmas of ultrasound technologies for primiparous Australian women

The practice of obstetric ultrasound scans has undergone significant expansion in the last two decades and is now a standard part of many women's antenatal care in Australia as elsewhere. This article reviews recent evidence about the value of obstetric ultrasound, summarizing debates and contradictions in research literature and practitioner guidelines. Pregnant women's interpretations of the significance of ultrasound are examined through multiple interviews with 34 study participants. We find that ultrasound has become an integral part of women's embodied experience of pregnancy, with its own pleasures and dilemmas. The increasing use of the technology has augmented the role of scientific biomedicine in the government of pregnancy. This must be understood in the light of trends toward individualized risk management in which the pregnant woman increasingly takes responsibility for the successful outcome of the pregnancy, in a context where pregnancy is discursively constructed as a risky domain of gendered experience in contemporary Australian society.     

Obstetric implications of neanderthal robusticity and bone density

Neanderthal pelvic morphology is not well understood, despite the recent find and analysis of the Kebara 2 pelvis. Many of the proposed hypotheses focus on the possible need for a larger birth canal. A previously unexplored aspect involves possible direct obstetric implications of bone robusticity and density. These characteristics ocan affect obstetrics in modern humans, especially the molding of the neonate's head during parturition: engineering studies have shown that denser neonate cranial bones undergo less deformation, and thicker (more robust) cranial bones would also be expected to deform less during the birth process. These bone characteristics may also result in a less flexible birth canal. Thus, more robust or denser bones could result in the need for a larger birth canal or a smaller neonate head, due to decreased flexibility. Examples from modern populations are discussed and the conclusions applied to Neanderthals, who are known to have had high bone robusticity and may have had high bone density, given their heavy musculature. (A positive association between muscle mass and bone density has been observed repeatedly in modern humans.) We conclude that bone robusticity and density may have obstetrical implications for Neanderthals, with particular importance for neonate head molding during birth.     

Gynecological Aspects of Obstetrical Delivery

Parturition should be looked upon as a physiological exercise, and ideally the multiparous state should be one of asymptomatic change associated with comfortable function. However, because obstetrics is a field in which serious complications may suddenly occur, the ideal is not always possible. Among the delayed effects of delivery is a group of gynecological complications which may affect the well-being of the woman so involved in later life. Such complications as uterine prolapse, cystocele, rectocele, enterocele, and genital fistula may be the grim aftermath of poor obstetric practice.The article reviews some of the advances in the prevention of maternal mortality and morbidity and emphasizes the important place of intelligent conservative obstetrics in the hands of both general physicians and specialists.     

Ancient DNA: would the real Neandertal please stand up?

Mitochondrial DNA sequences recovered from eight Neandertal specimens cannot be detected in either early fossil Europeans or in modern populations. This indicates that, if Neandertals made any genetic contribution at all to modern humans, it must have been limited, though the extent of the contribution cannot be resolved at present.     

Roles,risks, and responsibilities in maternity care: trainees' beliefs and the effects of practice obstetric training.

OBJECTIVES--To document the content of practice obstetric vocational training, the beliefs of general practitioner trainees about the roles of midwives and general practitioners in maternity care, and the risks of providing such care; and to ascertain if undergoing such training affects their beliefs. DESIGN--Confidential postal questionnaire survey. SUBJECTS--Random one in four sample of all general practitioner trainees in the United Kingdom on vocational training schemes or in training practices in autumn 1990. MAIN OUTCOME MEASURES--Beliefs scored on seven point Likert scales and characteristics of trainer and training practice. RESULTS--Of 1019 trainees sent questionnaires, 765 (75.1% response rate) replied; 638 (83.3%) had done some part of their practice year. Of their trainers, 224 (35.1%) provided full obstetric care. 749 (99%) and 364 (48%) trainees believed that midwives and general practitioners respectively have an important role in normal labour; 681 (91.7%) trainees believed that general practice intrapartum care is a high risk "specialty." Those trainees whose trainers provide full obstetric care were significantly more likely to believe that both midwives and general practitioners have an important role in abnormal labour and to see the provision of intrapartum care as an incentive to join a practice. CONCLUSION--In this series most general practitioner trainees believed that both midwives and general practitioners have important roles in maternity care. Exposure of trainees to the provision of full obstetric care while in their training practice resulted in a more positive attitude towards the provision of such care by general practitioners.     

The evolutionary history of childbirth

Consideration of the evolutionary and cross-cultural history of childbirth reveals many differences between the ways in which most human females have experienced childbirth and the ways in which most women in contemporary industrialized obstetric settings experience the event. In this paper I review two of these differences: the pain and anxiety of labor and delivery and the discontinuity of care provided for the mother and infant. I argue that much of the dissatisfaction with birth practices in the United States results from the failure of modern obstetric practice to meet the evolved needs of mothers and infants.

Craniocerebral injuries

The postconcussion syndrome is a definite entity, and the patient's complaints are due to legitimate injury. The following three factors contribute to the symptomatology:1. Headaches, caused by the associated sprain of the cervical spine with resultant radiculitis-giving rise to muscle spasm and suboccipital headaches.2. Vertigo, due to trauma of the vestibular and labyrinthine apparatus.3. A vasomotor imbalance and instability resulting from the reaction to "stress."In treatment of an unconscious patient great care must be taken to prevent anoxia and to balance the fluids and electrolytes. If coma develops following brain injury, hemorrhage into the cerebellar fossa as well as above the tentorium must be considered.     

Rehabilitation intervention in animal model can improve neuromotor and cognitive functions after traumatic brain injury: pilot study

The aim of the present study was to quantify the effect of multisensory rehabilitation on rats' cognition after an experimental brain trauma and to assess its possible clinical implications. The complex intermittent multisensory rehabilitation consisted of currently used major therapeutic procedures targeted at the improvement of cognitive functions; including multisensory and motor stimulation and enriched environment. We have confirmed this positive effect of early multisensory rehabilitation on the recovery of motor functions after traumatic brain injury. However, we have been able to prove a positive effect on the recovery of cognitive functions only with respect to the frequency of efficient search strategies in a Barnes maze test, while results for search time and travelled distance were not significantly different between study groups. We have concluded that the positive effects of an early treatment of functional deficits are comparable with the clinical results in early neurorehabilitation in human patients after brain trauma. It might therefore be reasonable to apply these experimental results to human medical neurorehabilitation care.     

Primary paranode demyelination modulates slowly developing axonal depolarization in a model of axonal injury

Neurological sequelae of mild traumatic brain injury are associated with the damage to white matter myelinated axons. In vitro models of axonal injury suggest that the progression to pathological ruin is initiated by the mechanical damage to tetrodotoxin-sensitive voltage-gated sodium channels that breaches the ion balance through alteration in kinetic properties of these channels. In myelinated axons, sodium channels are concentrated at nodes of Ranvier, making these sites vulnerable to mechanical injury. Nodal damage can also be inflicted by injury-induced partial demyelination of paranode/juxtaparanode compartments that flank the nodes and contain high density of voltage-gated potassium channels. Demyelination-induced potassium deregulation can further aggravate axonal damage; however, the role of paranode/juxtaparanode demyelination in immediate impairment of axonal function, and its contribution to the development of axonal depolarization remain elusive. A biophysically realistic computational model of myelinated axon that incorporates ion exchange mechanisms and nodal/paranodal/juxtaparanodal organization was developed and used to study the impact of injury-induced demyelination on axonal signal transmission. Injured axons showed alterations in signal propagation that were consistent with the experimental findings and with the notion of reduced axonal excitability immediately post trauma. Injury-induced demyelination strongly modulated the rate of axonal depolarization, suggesting that trauma-induced damage to paranode myelin can affect axonal transition to degradation. Results of these studies clarify the contribution of paranode demyelination to immediate post trauma alterations in axonal function and suggest that partial paranode demyelination should be considered as another “injury parameter” that is likely to determine the stability of axonal function.
