Mg. Karlowicz et Jl. Mcmurray, Comparison of neonatal nurse practitioners' and pediatric residents' care of extremely low-birth-weight infants, ARCH PED AD, 154(11), 2000, pp. 1123-1126
Objective: To compare outcomes and charges of health care delivery to extre
mely low-birth-weight infants by neonatal nurse practitioners (NNP) and ped
iatric residents.
Design: Retrospective cohort study.
Setting: A 56-bed neonatal intensive care unit (NICU) in a university teach
ing hospital.
Methods: Study population included all infants with birth weights less than
1000 g who were admitted to the NICU during the 2-year period between Sept
ember 1, 1994, and August 31, 1996. Infants who died earlier than 12 hours
of age, or who were admitted after 1 week of age or with major malformation
s, chromosomal abnormalities, or congenital infections were excluded. There
were separate teams of NNPs and residents providing care around the clock.
The study group included 201 infants with birth weights of less than 1000
g. The NNP team cared for 94 infants and the resident team cared for 107 in
fants.
Main Outcome Measures: Survival, length of stay, and total charges.
Results: Survival to discharge occurred for 71 NNP team infants (76%) and 8
2 resident team infants (77%) (P=.87). The median total length of stay was
87 days (range, 39-230 days) for NNP ream infants and 88 days (range, 41-36
5 days) for resident team infants (P=.54). There were no significant differ
ences between NNP infants and resident team infants in the prevalence of se
vere intracranial hemorrhage, threshold retinopathy of prematurity, or chro
nic lung disease at 36 weeks postconceptual age. Median total NICU hospital
charges were $141624 (range, $52020-$693018) for NNP team infants and $139
388 (range, $50178-$990865) for resident team infants (P=.89). There were n
o significant differences between NNP team infants and resident team infant
s in NICU charges for laboratory, radiology, or pharmacy services.
Conclusion: Neonatal nurse practitioners and pediatric residents provided c
omparable patient care to extremely low-birth-weight infants, with similar
outcomes and similar charges.
