Hospital neonatal services in the United States: variation in definitions, criteria, and regulatory status, 2008.

OBJECTIVE: The purpose of this study was to describe variation among states in designations of hospital neonatal services levels. STUDY DESIGN: We systematically searched all 50 states and District of Columbia governmental web sites and extracted definitions and levels terminology, functional and utilization criteria, regulatory compliance and funding measures, and citation of American Academy of Pediatrics (AAP) documents on levels of neonatal care. RESULT: Thirty-three states designate multiple graduated levels of neonatal services. Two to six levels were designated by numbers, titles, or both. Regulatory sources include hospital licensure, Certificate of Need or State Health Plan (CON/SHP), State Health Department, or an affiliated non-governmental entity (SHD/affiliate). Twenty-four states have a single source and nine have two or more. Functional criteria include population characteristics, respiratory care capabilities, and neonatal and cardiac surgery in 25 states. Utilization criteria include capacity, volume, occupancy, or case mix. Compliance mechanisms include license renewal, CON/SHP approval, and/or SHD/affiliate certification. Thirteen states link funding for the highest level of care through Medicaid, Maternal Child Health Title V funds or regional programs. AAP documents are cited or incorporated by reference in 22 states. CONCLUSION: All states regulate health care services and facilities. Definitions, criteria, compliance mechanisms, and regulatory source and status of neonatal levels of service vary widely. A consistent national approach would facilitate comparisons in neonatal outcomes and resource use and be informative to parents, providers, and policy makers. AAP documents could serve as a mechanism to foster such consistency.

Nosocomial sepsis in the neonatal intensive care unit.

During a 12-month study of the causes of and risk factors for nosocomial sepsis in a neonatal intensive care unit (NICU), we detected 23 episodes of nosocomial sepsis in 20 of the 155 infants at risk who were hospitalized in the NICU for at least one week. The associated mortality was 20%. Gram-positive organisms accounted for 15 (65%) of the episodes. Low birth weight, multiple gestation, and prolonged hospitalization were significant risk factors for nosocomial sepsis by univariate analysis; together, these three factors correctly predicted 80% of the infants with sepsis and 82% of the control subjects. By logistic regression analysis, however, length of stay was not a significant risk factor, but rather a confounding variable that was highly associated with birth weight. Analysis of risk factors for nosocomial sepsis showed that previous antibiotic therapy placed an infant at risk for candidemia; assisted ventilation was a risk factor for sepsis caused by group D Streptococcus and Candida albicans. Sepsis was related to infected or malfunctioning intravascular catheters in nine of the 20 infants with sepsis. Further investigation to determine strategies for preventing nosocomial septicemia in the low birth weight infant is warranted.

The association of Chlamydia trachomatis, Neisseria gonorrhoeae, and group B streptococci with preterm rupture of the membranes and pregnancy outcome.

There is conflicting evidence regarding a possible causal role for Chlamydia trachomatis in the development of preterm premature rupture of the membranes. We investigated the relative prevalence of endocervical infection with C. trachomatis and group B streptococci in patients with preterm premature rupture of membranes compared with a control group taken from the same obstetric population. C. trachomatis was isolated from 23/52 (44%) patients with preterm premature rupture of membranes versus 13/84 (15%) women in the control group (p less than 0.001). This association was independent of infection with group B streptococci or Neisseria gonorrhoeae. Group B streptococci were isolated from 16% of the patients with preterm premature rupture of membranes versus 4% of the control population (p less than 0.05). The risk of preterm premature rupture of membranes associated with group B streptococcal infection was independent of infection with C. trachomatis and N. gonorrhoeae. Endocervical infection with C. trachomatis did not significantly affect early maternal complication rates after delivery.

Localized pulmonary interstitial emphysema: treatment by bronchial occlusion.

Selective bronchial occlusion for the treatment of localized cystic pulmonary interstitial emphysema (PIE) offers a means to facilitate weaning from ventilatory support and to preserve potentially functional lung parenchyma. We employed a commercially manufactured balloon catheter, placed under direct visualization to occlude a left mainstem bronchus in two cases of localized PIE. This is the safest method for selective bronchial occlusion so far reported. Therapeutic success was achieved with either continuous or intermittent bronchial occlusion. Evaluation of pulmonary function with nuclear scintigraphy aids in determining the most appropriate position for the occluding catheter and permits assessment of the resultant improvements in pulmonary function.

The Fogarty balloon catheter as an aid to management of the infant with esophageal atresia and tracheoesophageal fistula complicated by severe RDS or pneumonia.

Early ventilatory failure in an infant with EA/TEF may prove difficult to manage because of the low resistance "vent" provided by the TEF. In this Case Report Fogarty balloon occlusion of the vent was possible and aided management of the patient who was not a candidate for primary repair of the anomaly.

Hypotension and bradycardia associated with airblock in the neonate. Preliminary report.

The hospital courses of 19 infants were analyzed retrospectively to determine if there was a relationship between hypotension and extra-alveolar air: interstitial emphysema, pneumomediastinum, and penumothorax. Of the 16 infants who subsequently developed PT, 12 had hypotension with IE/PM from one to 86 hours prior to the onset of PT (median 6.5 hours). When compared to blood pressure values obtained before the development of IE/PM, the decrease was statistically significant (p less than 0.001). Four of the six infants of greater than or equal to 38 weeks' gestation had bradycardia throughout the duration of EAA. Hypotension and bradycardia appear to be associated with airblock and thus may alert the physician to those infants who are at greatest risk for developing PT.
