Section Three: A Look Back
The Regionalized Perinatal Care Program

Editors'
Introduction
| In this chapter, Marguerite
Holloway, a contributing editor for Scientific
American and an adjunct professor of journalism
at Columbia University, looks back at the efforts
of The Robert Wood Johnson Foundation in the 1970s
and 1980s to encourage the regionalization of perinatal
services—the care delivered to mother and child shortly
before and after birth. The development of high-technology
care delivered in neonatal intensive care units made
it possible to save the lives of low-birthweight babies
who previously might have died. But not every hospital
could have the sophisticated equipment and specialized
staff to care for the small percentage of infants
requiring intensive care. It made sense, in the eyes
of many maternal and child health experts, to organize
services along geographic lines in a pyramid fashion.
Pregnant women at risk of delivering a low-birthweight
baby would be identified early and transferred up
the pyramid to a hospital capable of offering the
care necessary. At the top of the pyramid would be
a level III hospital—often at an academic medical
center—that would treat the most needy newborns in
a high-tech neonatal intensive care unit.

Building on regional arrangements
to provide care for specific illnesses in the United
States and reports of success with regional perinatal
care networks in Canada, the Foundation funded an
eight-site demonstration program—the Regionalized
Perinatal Care Program—to determine whether the regionalization
of perinatal services would work on a large scale
and with heterogeneous populations.
As Holloway observes, the path has
been rocky, and long-term successes have been elusive.
While the grantees funded under the program—as well
as the comparison sites—made progress toward regionalization
and lowering neonatal mortality rates, these achievements
often evaporated after funding ended. And from the
mid-1980s on, managed care organizations seemed to
be directing people to their own networks rather than
to networks built along geographical lines.
What is most disturbing about the
story is that while infant and neonatal mortality
rates have declined over the past 30 years, severe
racial, economic, and class differences in low-birthweight,
preterm delivery, and infant mortality rates persist.
Even though this is a retrospective review of past
programs, the hope is that it will stimulate new thinking
on strategies that the nation can pursue to improve
perinatal care. |

Chapter 8
Two or three times a week,
David A. Yost, clinical director at the Whiteriver Indian
Hospital in Arizona, transfers a pregnant patient by plane
or helicopter to the Good Samaritan Hospital in Phoenix, some
200 miles away. "It is for a wide variety of causes:
from a teenage mother with early labor, or twins, to complications
from trauma or diabetes," he says. "We have a lot
of preeclampsia, infectious disease, and diabetes, and a lot
of that leads to prematurity. We also have a lot of alcoholism,
fetal alcohol syndrome, and trauma from car accidents in our
pregnant patients." Because the Whiteriver Indian Hospital,
which is on the Fort Apache Indian Reservation in the eastern
part of the state, does not have a neonatal intensive care
unit, or NICU, these women and their babies—90 percent of
whom are covered by Medicaid—would be in danger unless they
could be quickly moved to a fully equipped center.
To try to ensure that Yost
and his counterparts in remote areas throughout Arizona have
access to university hospitals and large medical centers with
perinatologists or NICUs, the state maintains a voluntary
perinatal referral and transportation network called the Arizona
Perinatal Trust. "The system works," Yost says—except,
he adds, sometimes in the winter. "This is a high area
and there is lots of snow and in bad weather, if you can’t
get the airplane on the ground or the patient out the door,
you are stuck. But that is just part of living rural."
The
Emergence of Perinatal Care
The Arizona Perinatal Trust
arose out of a program funded by The Robert Wood Johnson Foundation
in the 1970s to regionalize administration of perinatal care—that
is, the care offered to a mother and child just before and
just after birth. Perinatal intensive care is a relatively
young field, one that emerged in the 1950s and 1960s as a
result of technological innovations. The development of ventilation
machines and better incubators led to the creation of modern
NICUs. In addition, ultrasound, amniocentesis, electronic
monitoring of fetal circulation during labor, and various
biochemical tests could reveal whether the baby’s growth was
slow, whether it was in distress, and whether it would be
able to breathe on its own. Armed with this detailed information
and new technology, pediatricians were able to identify high-risk
mothers and infants and make a difference.
The results of these interventions
were dramatic. Reports from several researchers showed that
the interventions had a powerful effect on mortality and morbidity.
Working in the 1960s in Quebec, Mary Ellen Avery, currently
at Harvard University, showed that state-of- the-art intervention
reduced the incidence of neurosensory damage—such as mental
retardation, cerebral palsy, and epilepsy—in very low-birthweight
babies from between 75 and 70 percent to between 20 and 15
percent.1
A 1973 paper in the British Medical Journal reported
that among 500 high-risk births at St. Thomas’ Hospital in
London there were no cases of mental retardation if modern
methods were used; normally, 10 such cases would have been
expected.2
Reports from various other areas—including Arizona and Ohio—also
pointed to increased survival when newborns were given access
to special care.3
But "the study that
had really excited the attention of pediatricians and pediatric
nurses was a report from Toronto," recalls Kenneth G.
Johnson, a physician who directed the Foundation-funded Regionalized
Perinatal Care Program. "There were two very good perinatal
networks, and they showed that it was just the access to specialized
care that was needed."
Thus by the late 1960s and
the early 1970s, it had become clear to the medical community
that neonatal mortality could be dramatically curtailed if
patients had access to specialists, to newly proven technologies,
and to NICUs. These things were in short supply at the time,
however, and it seemed apparent to many people practicing
and studying perinatal care that one cost-effective way to
improve access for parents in need would be to establish regional
networks. In such systems, hospitals with different capabilities
would coordinate care. A rural or community health center
such as Whiteriver Indian Hospital could transfer a mother
whom doctors deemed to be at high risk for premature delivery
to a facility that had the requisite NICU. Ideally, such regional
organizations would permit every mother and infant access
to the right level of care. And they would contain medical
costs, because hospitals would not have to build NICUs or
recruit perinatologists if they were part of a network with
a center that was already so equipped.
The medical community responded
quickly. In 1971, the American Medical Association issued
a statement on the benefits of regionalized perinatal care.
The following year, experts from the American Academy of Pediatrics,
the American Academy of Family Physicians, the American Medical
Association, the American College of Obstetricians and Gynecologists,
and the March of Dimes Birth Defects Foundation (then the
National Foundation-March of Dimes) met in San Francisco to
discuss regionalization. The participants formed a Committee
on Perinatal Health, and agreed that implementing systems
of community or regionalized perinatal care was imperative.
Other changes soon followed: the American College of Obstetricians
and Gynecologists formed a maternal-fetal medicine sub-board
in 1972; the American Academy of Pediatrics established a
specialization in neonatology-perinatology in 1973, and in
1975, neonatal-perinatal medicine became a board-certified
subspecialty.
The growing consensus of
the medical community was gathered in what has come to be
called by many the bible of perinatal care: "Toward Improving
the Outcome of Pregnancy: Recommendations for the Regional
Development of Maternal and Perinatal Health Services."
Published in 1976 by the March of Dimes Birth Defects Foundation,
the report outlined the need for a consistent system to screen
mothers and infants to determine who was at high risk; it
defined levels, or types, of hospitals and the care that was
appropriate to receive at each; it emphasized the need for
a uniform data system, and it stressed the importance of education
and outreach within the medical community.
The Regional Perinatal
Network
Regionalization of care
was not a new idea. Certain areas in the United States had
coordinated aspects of their medical services during the 1940s.
And in 1965, the federal government had authorized the funding
of so called Regional Medical Programs to increase the access
of heart disease, stroke, and cancer patients to new equipment
and procedures.4
But opposition by elements of the medical profession was fierce,
and the results of these efforts were ambiguous. For the most
part regionalization remained untested. "At that time,
there was a lot of disbelief," recalls George A. Little,
a neonatologist at the Dartmouth-Hitchcock Medical Center
in Lebanon, New Hampshire. "People needed to be convinced
about applying care in a regional fashion. It was not the
way that acute care was practiced."
As the groundswell of national
interest was emerging, The Robert Wood Johnson Foundation
began to explore whether regional perinatal networks were
indeed feasible, whether they could reduce neonatal mortality,
and if so, whether decreasing mortality resulted in an increase
in developmental or other problems as low-birthweight babies
survived. One of the principle catalysts for the Foundation’s
involvement was Irwin R. Merkatz, now chairman of the Department
of Obstetrics and Gynecology at the Albert Einstein College
of Medicine of Yeshiva University in the Bronx, and then at
Case Western Reserve University in Cleveland, Ohio. During
1972 and 1973, Merkatz spoke with Walsh McDermott, special
adviser to the Foundation, and David E. Rogers, president
of the Foundation, about the importance of undertaking a perinatal
demonstration project. It was an opportunity, they agreed,
to do widely what had been shown in only a few places as workable.
Within the Foundation, McDermott developed the idea of funding
a demonstration to test the feasibility of establishing regional
perinatal networks.
In 1974, the Foundation
issued a Call for Proposals. "The nuts and bolts were
pretty straightforward," Johnson says. "All the
hospitals in a defined area had to come together. And the
level I, level II, and level III hospitals had to agree to
follow a protocol and the use of a systematic problem-oriented
risk assessment system." Although definitions can vary
by state, in general, level I refers to a facility that can
care for normal or mildly ill newborns; level IIs can deal
with infants at moderate risk; and level IIIs have NICUs and
can tend to very sick infants. The networks also had to establish
a system of referral and maternal or infant transportation,
and had to conduct outreach
and education. In other words, the project would test the
major
elements that were being discussed in the perinatal community—and
that came to be enumerated in the March of Dimes report.
After reviewing 34 applications,
the Foundation selected eight sites (see Table 8.2 ) and awarded
$17.6 million in grants between 1975 and 1979. The grantees
were chosen because they were geographically, socially, and
economically diverse: the state of Arizona, Cleveland, Dallas
County in Texas, three contiguous areas in Los Angeles, Manhattan’s
Upper West Side, and a 15-county area around Syracuse, New
York. The thought was that if the demonstrations of regional
networks worked in these very different places, they would
serve as models for similar regions elsewhere.
Although there were vast
differences among the sites, many of the challenges
they faced in implementing networks were the same. According
to Johnson, friction between the community hospitals and the
level IIIs sometimes became debilitating. Doctors often did
not want to lose their patients; for some, it was simply a
matter of ego. In other places, reimbursement
for transportation expenses became a source of conflict.
Record keeping also proved
to be a challenge. Merkatz and Calvin J. Hobel, who served
as director of the Los Angeles South Bay Regional Perinatal
Project, designed a record-keeping system called The Problem
Oriented Perinatal Risk ssessment System, or POPRAS. POPRAS
enabled every participating institution and health care provider
to assess and record risk factors, medical information, and
care in a consistent way—a crucial need since patients were
going to be moving around. All pregnant women were to be evaluated
at least twice during the prenatal period, again during delivery,
and after birth. "It was a kind of sea change in the
whole movement," comments David E. Gagnon, president
of the National Perinatal Information Center in Providence,
Rhode Island. was an extensive risk identification system
that many later imitated."
Although POPRAS was designed
to be the centerpiece of the program—Kenneth Johnson recalls
that 60 to 70 percent of the grant money was spent on this
aspect—many of the participants had trouble initially setting
up the system. It was adopted by four of the sites. Moreover,
for some physicians, the uniform risk identification system
was threatening. They were worried that if a mother’s risk
score was high and they decided not to transfer her, they
would be vulnerable to malpractice action. "It was very
difficult to get the hospitals and the physicians used to
the assessment system," Johnson says. "They just
hated it." Other health care workers were concerned about
the privacy of their patients, an issue that still resonates
today. Johnson recalls that the program attempted to deal
with both concerns—by getting informed consent from the patients
and by showing that the scoring system was not perfect and
that physician judgment remained an important part of risk
assessment.
Despite the kinks, most
participants reported that the networks functioned well,5
and that regional involvement was between
80 and 100 percent except in some of the rural areas, such
as Arizona and upstate New York, where facilities were far-flung
and only about 60 to 70 percent of the hospitals in the region
became partners.6
It was also apparent that the identification of high-risk
mothers led to many more instances of maternal, as opposed
to neonatal, transfer—a sign of success to perinatologists.
"There was a shift from the emphasis on the transport
of the infant into the referral center to the transport of
the mother prior to birth," Gagnon says. "The whole
idea was that the best transport unit is the mother’s uterus."
Wendy Reynolds of Cleveland
agrees that this approach probably saved one of her children.
In July of 1977, her daughter, Alicia, was born two-and-a-half
months early. "She was in a hurry. She was going to come
whether we wanted her to or not," Reynolds says. "It
was fairly early in the morning, around 1 a.m., and I woke
up because I had to sneeze, and when I sneezed, my water broke.
My husband was home, thank God, and he took me to the hospital
then. And they monitored me for a little while. They were
trying to see if I was really going to give birth. And when
they determined I was, they transferred me." Reynolds
was moved by ambulance from a level I hospital to a nearby
university hospital. Twelve hours later, Reynolds gave birth
to Alicia, who stayed in the NICU until she was out of danger.
She finally came home in September—almost exactly to the day
that she was originally due.
Evaluating
the Program
Once the Regionalized Perinatal
Care Program ended, the next step was to quantify the project’s
effects, and, in particular, to address a concern that had
been raised at the outset. "The Foundation had many critics
at the time we announced the program," Johnson notes.
"One serious criticism was that we would reduce mortality,
but that these kids would have other problems and that we
were not addressing root causes."
In 1980, the Foundation
awarded $2.8 million to three researchers for a two-year evaluation
of the project. Marie C. McCormick, who was then at Johns
Hopkins University (and who is currently a professor of pediatrics
at Harvard University) and her colleagues Sam Shapiro and
Barbara H. Starfield set out to determine whether infant mortality
had fallen at the eight sites and, if so, whether that decline
was due to increased survival of high-risk infants or to a
decrease in the number of low-birthweight babies, to regionalization,
or to other factors. Their review ultimately appeared in The
Journal of the American Medical Association in 1985.
The team found that so much
had been happening to improve perinatal health nationally
that it was hard to see any effect at the eight projects that
differed from effects that were occurring in the rest of the
country. Neonatal mortality rates had fallen not only at the
eight sites but also in the comparison regions: an 18-county
area around Albany; six health districts in Brooklyn, New
York; a six-county area around Buffalo, New York; Harris and
Tarrant counties in Texas; an 11-county area around Rochester,
New York; San Diego county; and, finally, Wayne County, Michigan.
Between 1974 or 1975 and 1978 or 1979, neonatal mortality
in the funded areas fell an average of 19 percent, while it
dropped by 25 percent in the comparison areas.7
The evaluators attributed two-thirds of the decline to the
increased survival of low-birthweight babies. This increased
survival was due, in turn, the authors noted, to the early
identification of at-risk mothers and to the increased delivery
of high-risk infants in tertiary centers—that is, level IIIs.
Regionalization had clearly shifted the location of delivery:
by the end of the decade, 50 percent of low-birthweight babies
and 60 percent of very low-birthweight babies were being delivered
in level III centers in the foundation-funded areas. And,
according to Johnson, whereas before the program about 90
percent of the transfers were made after the baby was born,
about half of the transfers were now made before birth.
Again, in the comparison
areas, the same shift had occurred. "The centralization
of high-risk deliveries appeared so widespread that the special
effect of the RWJF program could not be detected," the
authors concluded. They noted that although the degree of
change in the comparison areas could not have been predicted
at the start of the program, the March of Dimes recommendations
published in 1976 and the publicity given to the Foundation’s
program "may have encouraged regionalization in the absence
of specific funding."
The evaluation also
addressed the issue of morbidity. The study found that, at
one year of age, there was no increased incidence of congenital
anomalies or developmental delays among low-birthweight babies.
Developmental delays and congenital anomalies actually decreased
by about 15 percent, and most dramatically in the very low-birthweight
group: by about 22 percent.8This
was not, however, the final word on low birthweight and child
health.
The Regionalized Perinatal
Care Program was followed by a study of long-term development
in babies of varying weights, to see how they fared at 8 to
10 years of age, and by a study of the effects of educational
intervention.9
Marie McCormick, the leader of the evaluation team, and several
colleagues continued to monitor some of the babies
born at the eight sites. They—and other researchers—found
that low-birthweight babies are at increased risk for behavioral
and learning disorders, asthma, and other health problems,
and that the incidence and severity of those problems increases
as birthweight falls.10
The findings from the evaluation
of the Regionalized Perinatal Care Program indicated that
a national trend toward regionalization of perinatal services
had emerged, to the degree that the Foundation-funded sites
represented, as L. Joseph Butterworth, a pediatrician at the
Children’s Hospital in Denver, Colorado, remarked many years
ago, "eight large boulders in a landslide."11
Yet the Foundation’s role was not insignificant, "What
the Foundation did was, in a sense, to support something that
was emerging at a critical time," says the National Perinatal
Information Center’s Gagnon. "They tested it and drew
attention to it."
The Regional Networks
After the Program
Over the years, the eight
Foundation-funded networks each went their separate ways.
Some fell apart—including the networks in Los Angeles and
Dallas County, Texas12—while
the others evolved. Arizona, for its part, took the money
left over from its grant, combined it with funds from Samaritan
Health Services and St. Joseph’s Hospital in Phoenix, and
in 1980 established the Arizona Perinatal Regional System,
Inc. This body oversees a voluntary certification system for
participants: the Arizona Perinatal Trust, which David Yost
is part of today. Cleveland and New York, in turn, received
state support to continue the networks in some form.
But Arizona and New York
were not able to keep the records system in place. "One
of the big problems we had was that The Robert Wood Johnson
Foundation had funded a huge statewide data system,"
says Deb Christian, executive director of the Arizona Perinatal
Trust. "After the program ended, entry of that data stopped."
Christian notes that the lack of a continuing record system
hinders the effectiveness of the network. The same holds true
in New York, where the state Department of Health is just
starting a statewide Perinatal Data System.
A dearth of data is something
that many perinatologists around the country are decrying,
particularly as they struggle to understand the persistence
of preterm delivery, low birthweight, and racial differences
in neonatal mortality. "A major barrier to monitoring
neonatal intensive care on a large scale is the lack of adequate
data sources," note Jeffrey D. Horbar and Jerold F. Lucey
in "The Future of Children," a report published
in 1995 by the David and Lucile Packard Foundation.13
The fact that perinatologists
are still calling for a uniform perinatal data system angers
Irwin Merkatz, who argues that POPRAS should have been maintained
and extended—with Foundation money. "There were many
systems that needed not only initial investment but continued
investment," he says. In addition, Merkatz believes that
the Foundation should have worked to get states more focused
on maternal and child health, to leverage the experience of
the networks while it was still hot. "My view is that
the Foundation was uniquely placed to build upon their success
and to make the next level of investment to keep that moving
forward," he says. "Now here we are in 1999, and
we are still lacking a comprehensive system of maternal and
child health."
Within the Foundation, there
is some consensus that there should have been more follow-up
for the Regionalized Perinatal Care Program. "The prevailing
philosophy at that time was that we would absolutely not do
follow-up grants," says Frank Karel, vice-president for
communications at The Robert Wood Johnson Foundation. "We
would plot out what was a reasonable trajectory and then it
was on its own." Today, he says, the Foundation has seen
the error of that rigidity; there is more openness to longer
programs and to follow-on initiatives.
The
Rural Infant Care Program
Although the Foundation
did not sustain its involvement with the eight regional perinatal
networks, it did continue to examine perinatal health through
a variety of programs, trying to identify gaps in the medical
delivery system and to address infant mortality and morbidity.
Between 1980 and 1985, the Foundation, under the Rural Infant
Care Program, gave $8.3 million to 10 medical schools to work
with state and local health departments in rural areas that
were isolated, where poverty was high, and where residents
had poor access to care. The project activities ranged from
organizing meetings among physicians, hospital administrators,
and public health department staff to expanding prenatal services
and instituting regionalization of perinatal care. A later
evaluation found that in funded areas neonatal mortality decreased
by 2.6 per 1,000 births; among blacks, that figure was even
higher: a reduction of 4.5 per 1,000.14
Three groups of comparison areas that did not receive Foundation
funding experienced no significant changes in neonatal mortality
rates. The decrease in mortality was attributed to reduced
mortality among low-birthweight babies—many more of whom were
being born in tertiary centers. The incidence of low-birthweight
deliveries remained the same, however.
The Rural Infant Care Program was intended
to follow up on the insights gleaned during the Regionalized
Perinatal Care Program. "We brought the same approach
to the 10 states with excessive infant mortality," Kenneth
Johnson says. "And there again we were able to form a
partnership between a maternal and child health department
in the state and the hospitals and the practitioners taking
care of their patients."
Regional Perinatal
Services Today
The landslide to which the
Foundation contributed eight boulders in the 1970s continued
into the 1980s. In 1978, the Department of Health and Human
Services issued guidelines mandating that neonatal and maternal
obstetrics be planned on a regional model,15
and by the end of the 1980s, 26 states had established referral
systems or had guidelines for perinatal networks in place.16
Regional networks have been
widely credited as one of the principle reasons for the rapid
decline in neonatal mortality rates in the last several decades.
(The other principal reason is the introduction in the late
1980s of surfactant replacement therapy, which reduced the
incidence of lung disease in newborns.) Over the years, several
studies have confirmed the value of transferring high-risk
mothers and infants into level IIIs. For example, Nigel S.
Paneth of Michigan State University found that mortality of
low-birthweight babies was significantly higher in level I
and level II centers than it was in level IIIs—in some areas,
mortality decreased by one third to one half when the babies
were tended to in tertiary centers.
Despite their recognized
effectiveness, however, regional perinatal networks have begun
to fall apart. They began to unravel in the 1980s, and the
process continued with greater velocity in the 1990s. Two
primary reasons explain this: first, the competition for patients
that has developed between level II and level III hospitals
and, second, the effect of managed care, which encourages
the transfer of patients within the managed care company’s
network rather than within geographically constructed networks.
The first of these reasons
stems, paradoxically, from the very recommendations the perinatal
community made in the early 1970s. Because of the new programs
in perinatology, a wealth of specialists began to hit the
job market and, since the level IIIs were filled up, started
working in level II hospitals. At about the same time, in
the 1980s, the number of obstetrical malpractice suits rose,
so more obstetricians started demanding that perinatologists
or neonatologists be in attendance in their hospitals. Currently,
these specialists appear to be in anything but short supply:
by some estimates, there are 3,500 neonatal physicians. "I
always incur a lot of rancor, because my sense is that we
have about twice as many as we need or should have,"
says James Lemons, professor of pediatrics at Indiana University
and chair of the American Academy of Pediatrics Committee
on Fetus and Newborn.
In addition, hospitals began trying
to attract a clientele in an increasingly competitive market,
and having an NICU was one way to do this. Indeed, the proliferation
of neonatal units has been stunning. In 1979, there were about
315 units in the United States; by 1997, there were 1,085.17
And between 1983 and 1997, according to David Gagnon of the
National Perinatal Information Center and his colleague Rachel
M. Schwartz, the number of neonatal beds has grown from 6,893
to 11,908.18
Gagnon estimates that there are twice as many beds as needed.
These changes have meant
that level II hospitals increasingly want to hold on to their
pregnant patients and newborns. The perinatologists, understandably,
want to practice their craft; the hospitals want to get some
return on their NICU or other neonatal investments. As a result,
says George Little of the Dartmouth-Hitchcock Medical Center,
"women with high-risk pregnancies may not be moved as
quickly as they were in the past because of interest in maintaining
these systems." The problem with this trend is that level
IIs still may not always have the volume of patients needed
to keep their practitioners as honed and skilled as they should
be.
Some of the literature seems
to support this conclusion. A recent study conducted in Missouri
found that there had been a shift of deliveries into level
IIs that had designated themselves perinatal centers, but
that neonatal mortality in those centers remained twice that
of the level IIIs.19
Another study found the same thing in South Carolina: "Very
low birthweight infants are more likely to survive if born
in level III hospitals than in level I or level II facilities,
with or without neonatologists."20
And a report by Ciaran S. Phibbs of Stanford University and
his colleagues concluded that "the rapid expansion of
level II and level II+ NICUs in California in the 1980s has
probably resulted in significantly higher risk-adjusted neonatal
mortality than would have occurred if more of the care for
high-risk deliveries had been concentrated in hospitals with
level III NICUs."21
David Gagnon is not sure
he agrees that the proliferation of level IIs inevitably leads
to poorer care. "My own personal feeling is that that
is not necessarily the case," he says. And he notes that
the ability of community and level II hospitals to deal with
high-risk infants is often comforting for mothers, who sometimes
ended up far from their homes, families, and physicians when
they were transferred—which was one of the criticisms of regional
perinatal networks.22
But, he adds, the proliferation "certainly cannot be
justified on an economic basis." Gagnon suspects that
the surplus of beds and specialists will lead to consolidation,
which he is already seeing in places like Minnesota, where
there used to be 10 NICUs in the state and there are now only
four, concentrated in urban areas.
Another challenge comes
from managed care, with its financial incentive to refer patients
within its own managed care network rather than to a competing
network. In some areas, hospitals that would have referred
high-risk mothers to a nearby university center are instead
holding on to their patients, hiring perinatologists and upgrading
their facilities—many have gone to the multi-million dollar
expense of building an NICU. Although definitive answers are
not yet available, this situation worries some observers who
fear that managed care is undermining the proven effectiveness
of regional networks and in some cases may be jeopardizing
infant health. ‘There is a basic mismatch between managed
care populations versus geographical populations," notes
Bernard Guyer, a professor and chair of the Department of
Population and Family Health Sciences at Johns Hopkins University.
"From what I am seeing, managed care is changing the
pattern of referral," adds Michigan State’s Nigel Paneth.
"Those patterns clearly have a lot to do with mortality."
What’s Next for Regional
Perinatal Networks
The crumbling of regional
perinatal networks is occurring within a health system that
continues to lag behind those of other developed countries.
Although infant and maternal mortality have declined steadily
since 1900—by more than 90 percent in total—America ranks
25th in the world in terms of infant mortality, with an average
of 7.2 deaths per 1,000 live births in 1997.23
By contrast, Japan has the lowest infant mortality rate, with
4 deaths per 1,000, and Sierra Leone has the highest, with
170 deaths, according to the United Nations.24
A closer look at the statistics
reveals another disturbing trend as well—the persistence of
a severe racial and economic gap in infant mortality rates
despite the overall national decline. In 1997, 13.7 per 1,000
black infants died in the United States as opposed to 6 per
1,000 white infants.25
In 1980, 22.2 per 1,000 black infants died compared to 10.9
per 1,000 white infants.26
Neonatal mortality rates exhibit the same racial and economic
gap.
In addition, neither the
low-birthweight rate nor the preterm delivery rate has improved
in America in the past 30 years.27
Indeed, the rates in the past decade and a half have been
increasing. Preterm deliveries increased from 9.4 per 1.000
in 1981 to 11.4 per 1,000 in 1997 for all newborns.28
Likewise, low-birthweight newborns increased from 6.8 per
1,000 in 1981 to 7.5 per 1,000 in 1997.29
Low-birthweight occurs in 7 percent of births—and those babies
are 40 times as likely to die as are heavier babies. And,
again, the incidence of low-birthweight and preterm delivery
is about two times as high among African Americans as it is
among whites.30
Although African Americans are responsible for 17 percent
of the country’s births, they have 33 percent of low-birthweight
babies and 38 percent of very low-birthweight babies.31
In 1998, for the first time
in decades, the neonatal mortality rate did not fall,32
but it is too early to tell whether this marks a decline in
the quality of perinatal care, and if so, whether that decline
has anything at all to do with the erosion of regional referral
systems and perinatal networks. What does seem clear, however,
is that the regionalized perinatal networks that emerged in
the 1970s introduced the possibility of bringing maternal
and child health into a unified system—and that this approach
powerfully improved health.
Experts agree that even
though the unified record-keeping model and the region-wide
system of communication were never universally adopted, they
are still relevant today: they offer a means of tracking risk
and care in a way that could shed greater light on the persistent
and poorly understood issues of preterm delivery, low birthweight,
and racial differences. So it remains perplexing and upsetting
to many observers—James Lemons and Irwin Merkatz among them—that
by the end of the 1970s the country seemed ideally poised
to build on
the regional perinatal networks and to further improve and
integrate maternal and child health care services, and that
now, at the beginning of the twenty-first century, such a
system is not in place. Given this, the strengths and failings
of the Foundation’s Regionalized Perinatal Care Program have
particular resonance today. The program’s accomplishments
as well as its limitations—and, some would argue, its failings—suggest
that a stronger national mechanism needs to be in place in
order to better protect infant and maternal health.

of Low Birth Weight." The Future of Children,
1995, 5(1), 19–34. Low birthweight and very low birthweight
can mean a host of problems throughout life. These babies
are at risk for neurodevelopmental and other problems such
as asthma, attention deficit disorder and learning disabilities.
Brain injury, including cerebral palsy, occurs in 6 to 8
percent of infants weighing between 1,500 and 2,500 grams
and in 20 percent of infants weighing between 500 and 1,500
grams. Although educational and social intervention can
ameliorate some of the developmental problems associated
with low birthweight, such programs are often expensive
and are not widely available. (return
