Cervical assessment certification and its impact on performance quality in the context of universal cervical screening.

OBJECTIVE: To assess the impact of the introduction of universal transvaginal cervical screening and certification on the quality of cervical length ultrasound images. METHODS: The present study included a retrospective cohort of singleton pregnancies that underwent transvaginal cervical length measurement at the anatomical scan (180/7 and 236/7 weeks) before (period A, 2015-2017) and after (period B, 2017-2019) the introduction of universal transvaginal cervical length screening. Independent observers blindly evaluated the images obtained for cervical length using a qualitative scoring method based on five criteria, according to the Fetal Medicine Foundation. RESULTS: In all, 6013 patients met the inclusion criteria, 3333 in period A and 2680 in period B. Maternal characteristics and risk factors for preterm birth were similar between the two periods. The acceptance of transvaginal cervical length measurement in period B was 95.5% in the overall cohort and 100% in the subgroup of high-risk patients. The quality score was significantly higher in period B than in period A. Among the image quality criteria, the anterior/posterior ratio, the correct magnification of the images, and the calipers' placement contributed significantly to the improved quality score in period B. Most of the sonographers performed better in period B, irrespective of the years of experience, but certificate holders obtained higher scores than non-certified sonographers, particularly those in mid-career. The identification of short cervix was significantly higher in period B than in period A. CONCLUSION: The implementation of universal transvaginal cervical length screening and the certification process are associated with improved quality of cervical length images, even among expert sonographers and in the presence of anatomical pitfalls.

Unanticipated consequences of COVID-19 pandemic policies on pediatric acute appendicitis surgery.

BACKGROUND: Global pandemics may limit access to specialized care, delaying diagnosis and treatment of common acute surgical diseases. We analyzed the impact of the novel coronavirus disease 2019 (COVID-19) pandemic on acute appendicitis at an urban tertiary care center. We hypothesize that pandemics are associated with delayed presentation and worsened clinical sequelae, specifically, higher incidences of perforation in children. METHODS: We retrospectively assessed patients admitted to our institution with acute appendicitis in pre-pandemic control (February 2018-June 2019) and COVID-19 (February 2020-June 2021) cohorts. Primary outcomes included complicated appendicitis rates (perforation/abscess/bowel obstruction), COVID-19 status, complications and travel distance to our institution. 1107 patients met inclusion criteria: 491 (44.4%) during the control period and 616 (55.6%) in the COVID-19 cohort. Statistical analysis involved t-tests, contingency tables and logistic regression modelling for key variables. RESULTS: A larger proportion of complicated appendicitis occurred during COVID-19 compared to controls (28.3% vs 38.8%, p < 0.001). Symptom duration at presentation and length of stay were not significantly different. Duration of antibiotic treatment, surgery length, readmission rate and travel distances were significantly higher during COVID-19. The pre-pandemic cohort had a significantly younger age distribution. CONCLUSION: Pediatric appendicitis was significantly impacted during COVID-19, demonstrated by increased rates of complicated appendicitis, surgery duration and antibiotic duration. This may be an unintended secondary consequence of patients avoiding healthcare facilities for non-pandemic related illnesses or lockdown policies. Government policies directing all provincial pediatric appendicitis cases to pediatric institutions increased travel distances for our patients and had unanticipated consequences and resource requirements on tertiary healthcare. LEVEL OF EVIDENCE: Level III for "Treatment Studies".

Comparison of sonographic fetal weight estimation formulas in patients with preterm premature rupture of membranes.

BACKGROUND: Estimation of fetal weight (EFW) by ultrasound is useful in clinical decision-making. Numerous formulas for EFW have been published but have not been validated in pregnancies complicated by preterm premature rupture of membranes (PPROM). The purpose of this study is to compare the accuracy of EFW formulas in patients with PPROM, and to further evaluate the performance of the most commonly used formula - Hadlock IV. METHODS: A retrospective cohort study of women with singleton gestations and PPROM, admitted to a single tertiary center between 2005 and 2017 from 220/7-330/7 (n = 565). All women had an EFW within 14 days of delivery by standard biometry (biparietal diameter, head circumference, abdominal circumference and femur length). The accuracy of previously published 21 estimated EFW formulas was assessed by comparing the Pearson correlation with actual birth weight, and calculating the random error, systematic error, proportion of estimates within 10% of birth weight, and Euclidean distance. RESULTS: The mean gestational was 26.8 ± 2.4 weeks at admission, and 28.2 ± 2.6 weeks at delivery. Most formulas were strongly correlated with actual birth weight (r > 0.9 for 19/21 formulas). Mean systematic error was - 4.30% and mean random error was 14.5%. The highest performing formula, by the highest proportion of estimates and lowest Euclidean distance was Ott (1986), which uses abdominal and head circumferences, and femur length. However, there were minimal difference with all of the first 10 ranking formulas. The Pearson correlation coefficient for the Hadlock IV formula was strong at r = 0.935 (p < 0.001), with 319 (56.5%) of measurements falling within 10%, 408 (72.2%) within 15% and 455 (80.5%) within 20% of actual birth weight. This correlation was unaffected by gender (r = 0.936 for males, r = 0.932 for females, p < 0.001 for both) or by amniotic fluid level (r = 0.935 for mean vertical pocket < 2 cm, r = 0.943 for mean vertical pocket ≥2 cm, p < 0.001 for both). CONCLUSIONS: In women with singleton gestation and PPROM, the Ott (1986) formula for EFW was the most accurate, yet all of the top ten ranking formulas performed quite well. The commonly used Hadlock IV performed quite similarly to Ott's formula, and is acceptable to use in this specific setting.
