Multicenter HIV and hepatitis B seroprevalence study.
Prior single institutional investigations have found unrecognized HIV seroprevalence in emergency department (ED) patients to range from 0.38% to 4%. A prospective, anonymous study of HIV and hepatitis B (HB) seroprevalence was performed on excess serum of all ED patients over two 48-hour periods in May and August, 1988, from 7 hospitals in the Portland metropolitan area. Demographics were known for 338/444 (76%) of patients. Forty-six percent were male, 85% white, with a median age group of 30-39 years. Ambulance transport, trauma, external blood, presentations requiring ED procedure(s), and acuity resulting in ICU admission were present on 21%, 7%, 10%, 34%, and 14% of patients, respectively. Two of 444 (.45%) patients were HIV +, one previously undiagnosed. Fifty-five of the 444 (12%) and 3 of 444 (0.6%) samples were positive for HBcAB and HBsAG respectively. Risk factor assessment was possible on 180/444 (40%) patients. HBcAB seroprevalence correlated with race (P less than 0.01), IV drug use (P less than 0.0001), and hospital location, (P less than 0.006) but were sensitive in detecting only 14%, 18%, and 38%, respectively, of HBcAB+ patients. HBcAB was not associated with the following factors: sex, area of residence, presence of blood externally, trauma, acuity of illness, ED procedures, or mode of transport. This data strongly support the use of universal body fluid precautions. Hepatitis B poses a significant and distinct risk to all emergency care providers. HB vaccination should be strongly advocated for all ED health care workers (HCWs). Emergency medicine multicenter studies are both desirable and feasible.

Racial differences in newborn intensive care morbidity in Alaska.
Birthweight-specific neonatal mortality for Alaska Natives is higher than for non-natives for the years 1987-1996. We investigated the reasons for this based on Level III Neonatal Intensive Care Unit information available from 1991-1996. We also investigated whether differences in mortality extended to measures of morbidity. There were less Native patients born at the tertiary care center for babies with birthweight < 1500 grams and 1500-2499 grams (64% for Natives and 87% for non-natives, p = .000). Differences in antenatal referral were only apparent for the population residing within the Anchorage/Mat-Su area. There were also less cesarean deliveries for Native infants that were born outside of the tertiary care center for both birthweight categories (25% for Native vs. 53% for non-native infants < 1500 grams, p = .01; 27% for Native vs. 48% for non-native infants 1500-2499 grams, p = .01). For Alaska Native babies < 1500 grams there was more necrotizing enterocolitis (13% in Native vs. 4.9% in non-native, p = .01), more severe retinopathy of prematurity (12% in Native vs. 4.6% in non-native, p = .01), and more bronchopulmonary dysplasia (49% in Native vs. 34% in non-native, p = .04). For Alaska Native babies 1500-2499 grams that needed ventilatory assistance there was more intraventricular hemorrhage (19% in Native vs. 7.4% in non-native, p = .003), more severe (grade 3-4) intraventricular hemorrhage (9.5% in Native vs. 0.9% in nonnative, p = .001), and more acquired sepsis (7.1% in Native vs. 1.7% in non-native, p = .02). Differences in access to Level III perinatal care and intrapartum care (cesarean delivery rates) are likely factors that contribute to the worse outcomes in the Alaska Native population.

Racial differences in birthweight-specific neonatal mortality in Alaska: 1987-1996.
OBJECTIVES: This study compared the neonatal mortality in the Alaska Native and non-native (primarily white) population in Alaska for a 10-year period (1987-1996). METHODS: Natality, mortality, and cause of death data were obtained from the State of Alaska's Bureau of Vital Statistics (BVS). Birthweight-specific and preventable birthweight-specific mortality were analyzed for babies < 1500 grams, 1500-2499 grams, and > or = 2500 grams birthweight. RESULTS: The low birthweight (LBW) and very low birthweight (VLBW) rates were similar for the Alaska Native and non-native populations. The neonatal mortality rate for the Alaska Native population was higher than for the non-native population (6.4 per 1,000 live births for Alaska Native vs. 4.1 for non-native for 1987-1991; 5.5 for Alaska Native vs. 3.5 for non-native for 1992-1996). Birthweight-specific mortality was higher in the Alaska Native population for all birthweight groups. The exclusion of non-preventable conditions accentuated the differences in mortality rates between the Alaska Native and non-native population for infants < 2500 grams birthweight. CONCLUSION: The higher neonatal mortality in the Alaska Native population is associated with a higher overall and preventable birthweight-specific neonatal mortality. The differences are therefore likely to reflect differences in access to and quality of perinatal care.

Determinants of blood pressure in infants admitted to neonatal intensive care units: a prospective multicenter study. Philadelphia Neonatal Blood Pressure Study Group.
There are few blood pressure (BP) data reported for premature and term newborn infants after 24 hours of age. To determine BP levels and BP trends in a representative population of infants admitted to neonatal intensive care units (NICUs), this study was conducted in 14 NICUs in the greater Philadelphia area. All infants admitted to the 14 NICUs during a 3-month period were entered into the study. BP data, along with data on clinical conditions and therapeutic interventions (independent variables), were prospectively collected by a uniform protocol. Systolic BP (SBP) and diastolic BP (DBP) were measured indirectly by oscillometry and recorded every 8 hours. Data from 608 infants followed up for 1 to 99 days after delivery generated 9911 infant-day records and 24,052 individual BP measurements. On day 1, birth weight and gestational age were strong correlates of SBP (r = 0.68, p < 0.0001 and r = 0.66, p < 0.0001, respectively) and DBP (r = 0.48, p < 0.0001 and r = 0.47, p < 0.001, respectively). During the first 5 days of life there was a progressive rise in SBP (2.23 to 2.67 mm Hg/day) and DBP (1.58 to 2.02 mm Hg/day) regardless of gestational age or weight at birth. After day 5 there was a more gradual increment in the daily SBP (0.24 to 0.27 mm Hg/day) and DBP (0 to 0.15 mm Hg/day). Stepwise linear multiple regressions were used to examine the multiple correlations among the independent variables and to build a regression model for BP. Gestational age and day of life emerged in the first two steps of the multiple regression analysis (multiple R = 0.463 and 0.655, respectively; p < 0.0001 for both). The multiple R values for day of life and gestational age were virtually identical to that for postconceptional age (day of life + gestational age at birth). Although other common diagnosis and treatment variables contributed a small amount to the total variance in BP, postconceptional age was the primary determinant of BP in this population of infants.

The next challenge for newborn intensive care in Alaska: improving the survival of the larger neonate.
Using information from our database, a review of mortality for the Newborn Intensive Care Unit at Providence Alaska Medical Center was conducted for 1987-1996. There has been a significant decline in mortality over the last decade (p = 0.003). An analysis of mortality by birthweight and gestational age groups demonstrated a decline in mortality (p = 0.005) for infants with birthweight < 2 kg and infants < or = 34 weeks gestation, but no change for infants > or = 2 kg and > or = 35 weeks gestation. As a result, larger and more mature babies now account for an increasing proportion of NICU deaths. For 1995 and 1996 the major contributors to mortality for the smaller neonates were respiratory distress syndrome and congenital and nosocomial sepsis/pneumonia. The major contributors to mortality for larger neonates were persistent pulmonary hypertension of the newborn, congenital heart disease, congenital diaphragmatic hernia, and primary birth asphyxia. A majority of deaths in the larger neonates were due to non-lethal causes. We contend that improved survival in the larger neonate is an important and achievable goal. The introduction of ECMO (Extracorporeal Membrane Oxygenation) for the NICU and a focused review of the neonatal cardiac program offers the best possible potential for achieving this goal.
