title: The impact of prematurity: a perspective of pediatric intensive care units.
abstract: OBJECTIVE
  To evaluate the relative resource use of pediatric intensive care unit (PICU) patients who had been born prematurely.
  
  
  METHODS
  Nonconcurrent cohort study.
  
  
  METHODS
  Consecutive admissions to 16 voluntary PICUs.
  
  
  METHODS
  A total of 431 formerly premature patients (FPP) and 5,319 nonpremature patients.
  
  
  METHODS
  None
  
  
  METHODS
  Patients with a history of prematurity and a prematurity-related complication or an anatomical deformity were compared for demographic and resource requirements to a group of non-premature patients by a bivariable logistic regression analysis that controlled for age as a co-morbid factor.
  
  
  RESULTS
  Compared with other patients, FPP were younger (34.9 +/- 2.2 months vs. 72.4 +/- 1.0 months; p < .001), readmitted to the PICU more often during the same hospitalization (11.1% vs. 5.5%; p < .001), used more chronic technologies (ventilators, gastrostomy tubes, tracheostomy tubes, and parenteral nutrition; 30.3% vs. 5.6%; p < .001), and had longer lengths of stay (5.98 +/-0.59 days vs. 3.56 +/- 0.12 days; p = .004). FPP had significantly higher use of ventilators (45.5% vs. 35.0%; p < .007) and lower use of arterial catheters (27.8% vs. 35.9%, p = .006) and central venous catheters (16.9% vs. 20.9%, p = .026) than nonprematures. The need for other PICU resources, including vasopressors, were similar.
  
  
  CONCLUSIONS
  FPP used more chronic and acute care resources than patients who were not prematurely born. Continued improvements in neonatal care will influence change in many aspects of the health care system. This will also affect the delivery of care to the current patient base of the PICU.
