Outcome-based comparison of SMFM and ISUOG definitions of fetal growth restriction.

OBJECTIVE: The recent international guidelines by the Society for Maternal-Fetal Medicine (SMFM) and the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) differ in their definitions of fetal growth restriction (FGR). Our aim was to compare the performance of the two definitions in predicting neonatal small-for-gestational age (SGA) and composite adverse neonatal outcome (ANO). METHODS: This was a secondary analysis of data from a prospective study of women referred for fetal growth ultrasound examination between 26 + 0 and 36 + 6 weeks' gestation. The SMFM and ISUOG guidelines were used to define pregnancies with FGR. The SMFM definition of FGR is estimated fetal weight (EFW) or abdominal circumference (AC) < 10th percentile. The ISUOG-FGR definition follows the Delphi consensus criteria and includes either EFW or AC < 3rd percentile or EFW or AC < 10th percentile combined with abnormal Doppler findings or a decrease in growth centiles. The primary outcome was the prediction of neonatal SGA, defined as birth weight < 10th percentile, and a composite of ANO, which was defined as one or more of: Grade-III or -IV intraventricular hemorrhage, respiratory distress syndrome, neonatal death, cord blood pH < 7.1, seizures and admission to the neonatal intensive care unit. Test characteristics (sensitivity, specificity, positive predictive value (PPV), negative predictive value and positive (LR+) and negative likelihood ratios) and area under the receiver-operating-characteristics curve were determined. The association between FGR detected by each definition and selected adverse outcomes was assessed using logistic regression analysis. RESULTS: Of the 1054 pregnancies that met the inclusion criteria, 137 (13.0%) and 55 (5.2%) were defined as having FGR by the SMFM and ISUOG definitions, respectively. Composite ANO and SGA neonate each occurred in 139 (13.2%) pregnancies. For the prediction of neonatal SGA, the SMFM-FGR definition had a higher sensitivity (54.7%) than did the ISUOG definition (28.8%). The ISUOG-FGR definition had higher specificity (98.4% vs 93.3%), LR+ (18.0 vs 8.2) and PPV (72.7% vs 55.5%) than did the SMFM definition for the prediction of a SGA neonate. The SMFM- and ISUOG-FGR definitions had similarly poor performance in predicting composite ANO, with sensitivities of 15.1% and 10.1%, respectively. CONCLUSIONS: The SMFM definition of FGR is associated with a higher detection rate for SGA neonates but at the cost of some reduction in specificity. The ISUOG-FGR definition has a higher specificity, LR+ and PPV for the prediction of neonatal SGA. Both definitions of FGR performed poorly in predicting a composite ANO. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

The implementation of an integrated information system for substance use screening in general medical settings.

UNLABELLED: The Massachusetts Screening, Brief Intervention and Referral to Treatment (MASBIRT) Program, a substance use screening program in general medical settings, created a web-based, point-of-care (POC), application--the MASBIRT Portal (the "Portal") to meet program goals. OBJECTIVES: We report on development and implementation of the Portal. METHODS: Five year program process outcomes recorded by an independent evaluator and an anonymous survey of Health Educator's (HEs) adoption, perceptions and Portal use with a modified version of the Technology Readiness Index are described. [8] Specific management team members, selected based on their roles in program leadership, development and implementation of the Portal and supervision of HEs, participated in semi-structured, qualitative interviews. RESULTS: At the conclusion of the program 73% (24/33) of the HEs completed a survey on their experience using the Portal. HEs reported that the Portal made recording screening information easy (96%); improved planning their workday (83%); facilitated POC data collection (84%); decreased time dedicated to data entry (100%); and improved job satisfaction (59%). The top two barriers to use were "no or limited wireless connectivity" (46%) and "the tablet was too heavy/bulky to carry" (29%). Qualitative management team interviews identified strategies for successful HIT implementation: importance of engaging HEs in outlining specifications and workflow needs, collaborative testing prior to implementation and clear agreement on data collection purpose, quality requirements and staff roles. DISCUSSION: Overall, HEs perceived the Portal favorably with regard to time saving ability and improved workflow. Lessons learned included identifying core requirements early during system development and need for managers to institute and enforce consistent behavioral work norms. CONCLUSION: Barriers and HEs' views of technology impacted the utilization of the MASBIRT Portal. Further research is needed to determine best approaches for HIT system implementation in general medical settings.
