OBJECTIVE: To determine the factors associated with an increasing rate of nosocomial infections in infants with very low birth weights. METHODS: Retrospective review of clinical and nosocomial infection databases for all infants with birth weights of 1500 g or less admitted to an academic neonatal intensive care unit between January 1, 1991, and December 31, 1997 (N = 1184). Two study periods were compared: 1991-1995 and 1996-1997. RESULTS: Among the 1085 infants who survived beyond 48 hours, the proportion who developed nosocomial infections increased from 22% to 31% (P =.001) and the infection rate increased from 0.5 to 0.8 per 100 patient-days (P<.001) during the period from 1996 to 1997. In that same period, the median duration of indwelling vascular access increased from 10 to 16 days (P<.001), and the median duration of mechanical ventilation increased from 7 to 12 days (P<.001). Although the device-specific rate of bloodstream or respiratory infections did not change, the increase in infections was directly attributable to the increasing proportion of infants who required these devices. In both study periods, the peak incidence of initial infection occurred between 10 and 20 days of age. For the entire sample, proportional hazard models identified birth weight, duration of vascular access, and postnatal corticosteroid exposure as significant contributors to the risk of infection. CONCLUSIONS: The increasing number of technology-dependent infants was the primary determinant in the increase of nosocomial infections. Because these infections occur in a small proportion of infants, understanding the host factors that contribute to this vulnerability is necessary to decrease nosocomial infections in neonatal intensive care units. 相似文献

The occurrence of congenital and nosocomial bacterial septicaemia has been documented by identifying the number of positive blood cultures by reviewing the laboratory and clinical records of 394 very low birth weight infants who were consecutively admitted to a neonatal intensive care unit over a 40-month period. The incidence of congenital septicaemia was 6% and of nosocomial septicaemia 17%. The commonest causes of congenital infection wereStreptococcus agalactiae Staphylococcus epidermidis andEnterococcus faecalis (each in 18% of cases). The commonest cause of nosocomial infection wasS. epidermidis (51% of cases), except in infants of birth weight less than 750 g. Risk factors for nosocomial infection were extremely low birth weight, very preterm birth and prolonged ventilation. Nosocomial infection was associated with significantly lengthened hospital admission. 相似文献

The use of CRIB (clinical risk index for babies) score in auditing the performance of one neonatal intensive care unit 总被引:1,自引:0,他引:1
PI Kaaresen G Døhlen HP Fundingsrud LB Dahl 《Acta paediatrica (Oslo, Norway : 1992)》1998,87(2):195-200
The CRIB (clinical risk index of babies) score was developed to overcome the disadvantages of birthweight-specific comparisons between neonatal units. The aims of this study were to assess the ability of CRIB score compared to birthweight and gestational age to predict hospital mortality in very low birthweight infants and to use CRIB score in auditing one unit's performance during a prolonged time period. The charts of 335 infants with birthweight ≤ 1500 g born between 1980 and 1995 were reviewed retrospectively. CRIB predicted hospital mortality significantly better than birthweight and gestation and performed equally well, whether the infants were treated with synthetic surfactant or not. When adjusting for CRIB score there was a significant improvement in the unit's performance, probably owing to the introduction of surfactant. As small samples tend to be associated with wide confidence intervals, use of CRIB is recommended in comparing risk adjusted mortality in a single unit over several years, as in this study, or between large groups of neonatal units over shorter periods. 相似文献

We investigated infants with respiratory distress within 4 days of birth whose mothers had not received antibiotic prophylaxis to evaluate the frequency and etiology of bacterial infection and associated risk factors. The study was conducted on 261 infants suffering respiratory distress admitted to a Brazilian neonatal intensive care unit, 94 per cent of whom were born prematurely. Gestational and delivery history; bacteriological cultures of blood, cerebrospinal fluid, tracheal aspirates and urine; complete and differential blood counts; a urinary group B streptococcal latex antigen test; and a chest radiograph were analysed. Indications of infection were found in 38.7 per cent and confirmed in 11.9 per cent of the neonates. Gram-positive (70.9 per cent) and gram-negative bacteria (29.1 per cent) were found in 31 cases of confirmed early bacteremia. Group B Streptococcus was the predominant causative agent (19.4 per cent) in infants exhibiting confirmed infection. Culture-proven infection was more frequent among infants delivered vaginally (adjusted OR = 2.53, p = 0.05) or born to mothers with signs of intra-amniotic infection (adjusted OR = 2.83, p = 0.04). Preventive measures against early bacterial infection in preterm infants from this population are strongly warranted. 相似文献

Variations in central venous catheter-related infection risks among Canadian neonatal intensive care units 总被引:6,自引:0,他引:6
Chien LY Macnab Y Aziz K Andrews W McMillan DD Lee SK;Canadian Neonatal Network 《The Pediatric infectious disease journal》2002,21(6):505-511
BACKGROUND: The objective of this study was to examine central venous catheter (CVC)-related nosocomial blood stream infection risks of umbilical venous, percutaneous and Broviac catheters, as well as variations in CVC use and CVC-related risk for nosocomial blood stream infection in the neonatal intensive care unit (NICU). METHODS: A cohort study was performed based on 19,507 infants admitted to 17 NICUs in the Canadian Neonatal Network from January, 1996, through October, 1997. Information on these subjects was prospectively collected by trained abstractors. Incidence of infection was measured as infection episodes per 1000 patient days. The risk ratio (RR) of CVC use for nosocomial blood stream infection was calculated as the infection rate during catheter days divided by the infection rate during noncatheter days. Using a Poisson regression model we examined the adjusted RR of CVC use for nosocomial blood stream infection, controlling for patient characteristics and illness severity at admission. Interinstitutional variations in CVC-related infection risks were examined by stratified analyses. RESULTS: CVC were used in 22.5% of patients. The incidence of nosocomial blood stream infection was 2.9 per 1000 noncatheter days, 7.2 per 1000 umbilical venous catheter days, 13.1 per 1000 percutaneous catheter days and 12.1 per 1000 Broviac catheter days. The RR for nosocomial blood stream infection, adjusted for differences in patient characteristics and admission illness severity, was 2.5 for umbilical venous catheter, 4.6 for percutaneous catheter and 4.3 for Broviac catheter (P < 0.05). There were significant (P < 0.05) risk-adjusted variations in CVC-related infection risks among NICUs. CONCLUSIONS: CVC use increased the risk of nosocomial blood stream infection. The risk of nosocomial blood stream infection in percutaneous and Broviac catheters was 70 to 80% higher than in umbilical venous catheters. There was significant variation in CVC-related infection risks among Canadian NICUs. 相似文献

Aims: To examine the frequency of and risk factors for bacteraemia in children hospitalised with respiratory syncytial virus (RSV) infection; and to determine current use of antibiotics in hospitalised children with RSV infection. Methods: Retrospective study of all children, aged 0–14 years, admitted to a tertiary children''s hospital with proven RSV infection over a four year period. Children with concurrent bacteraemia and RSV infection were identified, and risk factors examined for bacteraemia. The case notes of a randomly selected comparison sample of 100 of these RSV infected children were examined to assess antibiotic use and population incidence of risk factors for severe RSV infection. Results: A total of 1795 children had proven RSV infection, and blood cultures were sent on 861 (48%). Eleven (0.6%) of the 1795 RSV positive children had bacteraemia. RSV positive children had a significantly higher incidence of bacteraemia if they had nosocomial RSV infection (6.5%), cyanotic congenital heart disease (6.6%), or were admitted to the paediatric intensive care unit (2.9%). Forty five (45%) of the random comparison sample of RSV infected children received antibiotics. Conclusions: Bacteraemia is rare in RSV infection. Children with RSV infection are more likely to be bacteraemic, however, if they have nosocomial RSV infection, cyanotic congenital heart disease, or require intensive care unit admission. 相似文献

Neonatal neutropenia associated with maternal hypertension poses a risk for nosocomial infection 总被引:2,自引:0,他引:2
One hundred and six neonates of 24–32 weeks gestation born to hypertensive mothers and 106 concurrent control infants of
normotensive mothers were evaluated to determine the relationship between maternal hypertension and neonatal neutropenia and
the risk of nosocomial infection developing in neutropenic infants.. Complete blood counts were performed on both cohorts
and retrospectively evaluated. Neutropenia was diagnosed using published reference ranges for infants with birth weight ≤1500 g
and >1500 g. Evidence of nosocomial infection based on a positive blood culture with supportive clinical signs of sepsis was
documented. The incidence of neutropenia among infants of hypertensive mothers was not significantly different from that among
infants of normotensive mothers (21% vs 24%), but the duration of neutropenia was significantly longer in the infants of hypertensive
mothers (P = 0.0001). Nosocomial infection was more frequent in neutropenic than the non-neutropenic hypertensive mothers' infants (55%
vs 12%, P = 0.0002).
Conclusion Although there is no difference in the incidence of neonatal neutropenia between infants of hypertensive mothers and those
of normotensive mothers, the former group has an increased risk of nosocomial infection in neutropenic infants of hypertensive
mothers. This may be related to prolonged neutropenia which was found in these infants in the present study.

OBJECTIVE: Estimating the risk of in-hospital mortality in the neonatal intensive care unit provides important information for health care providers, and several neonatal illness severity scores have been developed. Histologic chorioamnionitis (HCA) is a known cause of neonatal morbidity and mortality. To date, the relationship between HCA and neonatal illness severity scores has not been rigorously tested. In this study, the relationships among HCA, initial illness severity, and neonatal outcomes were analyzed in very low birth weight (VLBW) newborns admitted to the neonatal intensive care unit. DESIGN: Prospective. SETTING: Neonatal intensive care unit. PATIENTS: A total of 116 VLBW inborn infants (gestational age, 28.1 +/- 2.82 wks; birth weight, 1009 +/- 312 g) were categorized as HCA-positive (n = 67) and HCA-negative (n = 49). INTERVENTIONS: Placental histology was performed to identify HCA. Illness severity evaluation included several different neonatal illness severity scores-Clinical Risk Index for Babies (CRIB), CRIB-II, Score for Neonatal Acute Physiology-II (SNAP-II), and Score for Neonatal Acute Physiology Perinatal Extension-II (SNAPPE-II)-as well as the recording of severe morbidity and in-hospital mortality. MEASUREMENTS AND MAIN RESULTS: HCA-positive VLBW newborns showed significantly lower gestational age (p < .0001) and birth weight (p = .0010), together with higher CRIB, CRIB-II, SNAP-II, and SNAPPE-II scores at admission to the NICU (p = .0001) and mortality rate (p = .0018) than HCA-negative infants. After adjustment for gender and gestational age in a multivariable logistic regression analysis, HCA was found to be an independent predictor of high illness severity: CRIB > 5 (odds ratio [OR], 21.37; 95% confidence interval [CI], 6.24-73.21); CRIB-II > 10 (OR, 56.17; 95% CI, 6.75-467.2); SNAP-II > 22 (OR, 43.05; 95% CI, 11.9-155.7), and SNAPPE-II > 42 (OR, 48.95; 95% CI, 10.18-235.4) (all p values <.0001). CONCLUSIONS: Our findings indicate that HCA is a major predictor of morbidity and mortality in VLBW newborns. 相似文献

Our purpose was to determine mortality and morbidity rates and selected outcome variables for infants weighing less than 1500 g, who were admitted to the neonatal intensive care unit of our hospital from 1997 to 2000. The ultimate goal of the study was to define a model for developing a regional database. Information on all very low birth weight (VLBW) admissions to a tertiary level neonatal intensive care unit (NICU) in Ankara between January 1997 and December 2000 was prospectively collected by three neonatologists using a standard manual of operation and definitions. The data consisted of patient information including sociodemographic characteristics; antenatal history; mode of delivery; APGAR scores; need for resuscitation; admission illness severity (Clinical Risk Index for Babies-CRIB) and therapeutic intensity (Neonatal Therapeutic Intensity Scoring System-NTISS); selected NICU parameters and procedures such as respiratory support, surfactant therapy, and postnatal corticosteroid therapy; and selected patient outcomes such as intraventricular hemorrhage, septicemia, necrotizing enterecolitis, retinopathy of prematurity, and chronic lung disease. The number of VLBW admissions to the NICU was 133, with 51 (28.6%) referrals from other maternity centers. The mean birth weight and gestational age of the infants were 1175 +/- 252 g and 30.3 +/- 2.9 weeks, respectively. One hundred and seventeen of 133 cases (88.7%) received at least one antenatal care visit. The median CRIB and NTISS scores were 4.5 and 31, respectively. Antenatal steroids had been given to 74 (55.6%) infants. Surfactant treatment and respiratory support were given to 33 (24.8%) and 73 (54.8%) infants, respectively. Among selected outcomes, chronic lung disease (CLD), threshold retinopathy of prematurity (ROP), severe intraventricular hemorrhage (IVH > or = grade III), nosocomial infection and necrotizing enterocolitis (NEC) were encountered in 14 (12.6%), 9 (8.1%), 3 (2.2%), 34 (25.5%) and 35 (26.3%) of the infants, respectively. Overall survival rate was 83.5% (111/133); most of the deceased cases were under 750 g (12/22). It was prospectively shown that 111 (100%) of the surviving infants could be regularly followed in a newborn follow-up clinic to provide health maintenance, developmental assessment and support. Compared with reports from other developing countries, VLBW infants at our center had higher survival rates. Compared to developed countries, survival rate was lower, especially for extremely very low birth weight infants. There is interaction between birth weight and survival rate. Among selected neonatal outcomes, chronic lung disease, threshold retinopathy, severe intraventricular hemorrhage (IVH > or = grade III) and nosocomial infection rates at this center were comparable with some reports from developed nations. 相似文献

Neonatal neutropenia occurs in approximately 50% of newborns delivered by women with pregnancy-induced hypertension. It is thought to be transient, independent of birth weight and gestational age, and unassociated with significant risks, including infection. It recently was suggested that neonatal neutropenia occurs primarily in smaller, younger neonates, is related to the severity of pregnancy-induced hypertension, and importantly, may be associated with an increased risk for nosocomial infection. We examined these points in a large inborn population in consecutive years, performing retrospective (n = 110, 1989) and prospective (n = 151, 1990) studies in low birth weight (less than or equal to 2200 g) neonates delivered by women with pregnancy-induced hypertension. Overall, 40% to 50% of neonates studied developed neonatal neutropenia, and they were younger and smaller (P less than .01) than non-neutropenic neonates. In the prospective study, neutropenic neonates were more likely to have mothers with severe pregnancy-induced hypertension (P less than .001), and the incidence of neonatal neutropenia was primarily among neonates less than 30 weeks of gestation and less than 1500 g birth weight, approximately 80% vs 35% to 45% in older, larger neonates or infants (P less than .001). Although nosocomial infection occurred more frequently among the group of neutropenic neonates in the prospective study (P less than .02), the incidence was similar to that in matched non-neutropenic controls delivered of normotensive women. Thrombocytopenia (less than 100,000/mm3) was not more frequent in neutropenic neonates.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

OBJECTIVE: To assess the usefulness of clinical risk index of babies (CRIB score) in predicting neonatal mortality in extremely preterm neonates, compared to birth weight and gestation. METHODS: 97 preterm neonates with gestational age less than 31 weeks or birth weight less than or equal to 1500 g were enrolled for the prospective longitudinal study. Relevant neonatal data was recorded. Blood gas analysis results and the maximum and the minimum FiO2 required by babies in first 12 hours of life were noted. Mortality was taken as death while the baby was in nursery. The prediction of mortality by birth weight, gestational age and CRIB score was done using the Logistic model, and expressed as area under the ROC curve. RESULTS: The area under the ROC curve for birth weight, gestational age and CRIB score was almost the same, the areas being 0.829, 0.819 and 0.823 respectively. Hence CRIB score did not fare better than birth weight and gestational age in predicting neonatal mortality. CONCLUSION: The CRIB score did not improve on the ability of birth weight and gestational age to predict neonatal mortality in the study. 相似文献

AIM: To determine the relation between the level of initial neonatal care and in-hospital mortality of infants born before 33 wk of gestation in the era of surfactant therapy. METHODS: A 1 y prospective population-based survey was conducted in the north of France, as part of the EPIPAGE (Epidemiologie des Petits Ages Gestationnels) survey. Perinatal data were recorded for 585 very premature newborns transferred to a neonatal intensive care unit in 1997. The relation between the level of the neonatal unit that provided care for the first consecutive 48 h and in-hospital mortality was assessed by multivariate logistic regression, and adjusted for perinatal data and initial disease severity, estimated by the Clinical Risk Index for Babies (CRIB). RESULTS: The average gestational age (mean +/- SD) was 31.6 +/- 0.62 wk in level I, 30.7 +/- 0.21 in level II, 29.9 +/- 0.13 in non-teaching level III, and 29.0 +/- 0.15 in the level III teaching unit (p < 0.0001). The mean in-hospital mortality rate was 8.4% and did not differ by level of care (p(trend) = 0.17). After adjustment for perinatal data and CRIB, however, with the teaching unit as the reference, the risk of death was significantly higher in level I-II units [adjusted odds ratio (ORa) = 7.9, 95% confidence interval (95% CI) 2.2-29.1], but not in the non-teaching level III units (ORa = 0.8, 95% CI 0.3-2.1). CONCLUSION: In-hospital mortality in non-teaching level III units was similar to that in a teaching unit, but significantly higher in level I-level II units. Neonatal care of newborns delivered before 33 wk of gestation should initially occur in level III units. 相似文献

AIM—To determine the perinatal factors associated with initial illness severity (measured by the CRIB (clinical risk index for babies) score) and its relation to survival to discharge.
METHODS—A retrospective study was made of intensive care nursing records on 380 inborn babies, of less than 31 weeks gestation or 1501 g birthweight, admitted to one unit between 1984-6 and 1991-4.
RESULTS—Between the two time periods mean initial illness severity score increased significantly from 2.8 to 3.9. This was the result of an increase in the maximum appropriate inspired oxygen concentration in the first 12 hours. Risk adjusted survival did not improve over time after accounting for gestation but was significantly greater after accounting for CRIB score. Illness severity score was also significantly inversely associated with gestation and 1 and 5 minute Apgar scores, using multiple regression analysis. Between the two time periods there was also a 92% increase in the admission rate of babies under 31 weeks gestation, higher median 1 and 5 minute Apgar scores (6 vs 5 and 9 vs 8, respectively), more multiple births, and more caesarean section deliveries.
CONCLUSIONS—The increase in illness severity score and admission rate may reflect changes in obstetric practice. The increase in illness severity score may also reflect changes in early neonatal care. However, after adjusting for CRIB score, risk adjusted mortality fell significantly, suggesting that neonatal care 12 hours from birth onwards had improved with time.
