Pediatric Critical Care-Associated Parental Traumatic Stress: Beyond the First Year.

OBJECTIVES: Perform a longitudinal analysis of parental traumatic stress up to 30 months after PICU discharge. DESIGN: Prospective observational cohort study. SETTING: Two tertiary care children's hospitals with mixed medical/surgical/cardiac PICUs. SUBJECTS: Parents of patients unexpectedly admitted to the PICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Two hundred sixty-five parents of 188 children were enrolled. Of the 195 parents who completed the 3-9-month assessments, 29 (14.8%) met posttraumatic stress disorder (PTSD) qualification on the PTSD Symptom Scale Interview for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Multivariable analysis showed parents who met acute stress disorder (ASD) qualification (odds ratio [OR] 8.01; 95% CI 2.64-24.3), parents of children with Pediatric Overall Performance Category score of severe or coma at discharge (OR 5.21; 95% CI 1.65-16.4), parents who had concerns for their child's permanent injury (OR 1.82; 95% CI 1.36-2.43), and parents who reported increased knowledge of child illness during admission (OR 1.82; 95% CI 1.13-2.93) had increased odds of developing parental PTSD. Of the 175 parents (66%) who completed the 18-30-month assessments, 22 (12.5%) met PTSD qualification. Multivariable analysis showed parents who met ASD qualification (OR 4.19; 95% CI 1.12-15.7), parents who had a history of a family member or themselves being admitted to ICU (OR 6.51; 95% CI 1.43-29.6), and parents who had concerns of child's susceptibility to death post discharge (OR 1.58; 95% CI 1.19-2.09) had increased odds of developing parental PTSD. At 18-30 months post discharge, parents who met the PTSD qualification were more likely to report a decrease in household income following discharge (OR 9.23; 95% CI 1.71-49.9). CONCLUSIONS: Parental PTSD remains a significant morbidity of PICU admission for a subgroup of parents greater than 18 months post admission. Identifiable risk factors will inform the development of targeted interventions.

Decreased Antibiotic Exposure for Suspected Early-Onset Sepsis in the Neonatal Intensive Care Unit Through Implementation of an Antimicrobial Time-out.

Antimicrobials are among the most frequently prescribed drugs in the neonatal intensive care unit (NICU), although most neonates exposed lack a bacterial infection. Overuse of antimicrobials carries risk to the patient and fosters the development of resistant organisms. Strategic and systematic processes hold promise to limit the unnecessary use of these drugs in this population. This study reports a quality improvement initiative in which 2 antimicrobial stewardship strategies were implemented in a large, regional NICU setting: an automatic stop order and an antimicrobial time-out. Antimicrobial use was compared before and after implementation. These 2 simple strategies were associated with a nearly 30% reduction in antibiotic use (31 days per 1000 patient days).

Serum Decorin, Biglycan, and Extracellular Matrix Component Expression in Preterm Birth.

Preterm birth is a leading cause of infant morbidity and mortality. Decorin and biglycan are proteoglycans that play key roles in maintaining the connective tissue matrix and tensile strength of human fetal membranes and have been previously linked to PPROM. Extracellular matrix proteins, such as matrix metalloproteinase 2 (MMP-2), matrix metalloproteinase 9 (MMP-9), TIMP metallopeptidase inhibitor 1 (TIMP-1), TIMP metallopeptidase inhibitor 2 (TIMP-2), and collagen VI (COL-6), have also been linked to PPROM and may have utility in a serum-based screening model for this condition. To define the natural course of serum decorin and biglycan expression throughout the duration of healthy pregnancy, to explore patterns of serum decorin and biglycan expression in serum of asymptomatic women who go on to develop spontaneous preterm labor, and to investigate the potential role for matrix metalloproteinases, their inhibitors, and collagen VI in a serum-based screening model to predict PPROM. Serum decorin level decreases less than 1% per week, and serum biglycan decreases by 2.9% per week over the duration of healthy pregnancy. Serum decorin and biglycan concentrations do not differ in spontaneous preterm labor cases compared with those in controls. Mean concentrations of MMP-2, MMP-9, TIMP-1, TIMP-2, and COL-6 do not differ in PPROM cases compared with those in controls. We have demonstrated that serum decorin and biglycan concentrations remain stable throughout the duration of normal pregnancy and are not early indicators of preterm labor, while common MMPs, TIMPs, and collagen VI are not early indicators of PPROM.
