The script concordance test (SCT) is used in health professions education to assess a specific facet of clinical reasoning competence: the ability to interpret medical information under conditions of uncertainty. Grounded in established theoretical models of knowledge organization and clinical reasoning, the SCT has three key design features: (1) respondents are faced with ill-defined clinical situations and must choose between several realistic options; (2) the response format reflects the way information is processed in challenging problem-solving situations; and (3) scoring takes into account the variability of responses of experts to clinical situations. SCT scores are meant to reflect how closely respondents' ability to interpret clinical data compares with that of experienced clinicians in a given knowledge domain. A substantial body of research supports the SCT's construct validity, reliability, and feasibility across a variety of health science disciplines, and across the spectrum of health professions education from pre-clinical training to continuing professional development. In practice, its performance as an assessment tool depends on careful item development and diligent panel selection. This guide, intended as a primer for the uninitiated in SCT, will cover the basic tenets, theoretical underpinnings, and construction principles governing script concordance testing.

All women with pre-existing type 1 or type 2 diabetes should receive preconception care to optimize glycemic control, assess complications, review medications and begin folate supplementation. Care by an interdisciplinary diabetes healthcare team composed of diabetes nurse educators, dietitians, obstetricians and diabetologists, both prior to conception and during pregnancy, has been shown to minimize maternal and fetal risks in women with pre-existing type 1 or type 2 diabetes. Gestational Diabetes MellitusThe diagnostic criteria for gestational diabetes mellitus (GDM) remain controversial; however, the committee has chosen a preferred approach and an alternate approach. The preferred approach is to begin with a 50 g glucose challenge test and, if appropriate, proceed with a 75 g oral glucose tolerance test, making the diagnosis of GDM if !1 value is abnormal (fasting !5.3 mmol/L, 1 hour !10.6 mmol/L, 2 hours !9.0 mmol/L). The alternate approach is a 1-step approach of a 75 g oral glucose tolerance test, making the diagnosis of GDM if !1 value is abnormal (fasting !5.1 mmol/L, 1 hour !10.0 mmol/L, 2 hours !8.5 mmol/L). Untreated GDM leads to increased maternal and perinatal morbidity, while treatment is associated with outcomes similar to control populations. Preconception carePreconception care for women with pregestational diabetes is associated with better outcomes (10,11). Although multidisciplinary clinics improve outcomes, <50% of women receive such care. Women who are heavier, younger and smokers, and who have a lower socioeconomic status, lower health literacy and a poor relationship with their healthcare provider, are less likely to receive preconception care (11e14). Some, but not all, have shown that women with type 2 diabetes are also less likely to receive preconception care (7,15). Higher glycated hemoglobin (A1C) levels are associated with poorer outcomes, but even women who achieve tight glycemic control (A1C <7.0%) have an increased risk of complications, which may be caused, in part, by maternal obesity (16,17). By discussing pregnancy prior to conception, healthcare providers may be able to improve outcomes by educating women Contents lists available at SciVerse ScienceDirect Canadian Journal of Diabetes j o u r n a l h o m e p a g e : w w w . c a n a d ia n j o u r n a l o f d i a b e t e s . c o m

Compared with the neonatal growth standards, the fetal growth standards are better in identifying increased risk of respiratory morbidity and IVH among preterm SGA infants.
