Avoiding Inadequate Intrapartum Antibiotic Prophylaxis for Group B Streptococci.

OBJECTIVE: To estimate the frequency and reasons for inadequate group B streptococci (GBS) prophylaxis at our institution and to estimate what proportion of cases can be avoided with perfect protocol adherence. METHODS: This was a retrospective cohort study of neonates born to GBS-colonized women who received inadequate prophylaxis between April 30, 2013, and May 1, 2014. The maternal chart was analyzed to categorize each case as avoidable (adequate time on labor and delivery to receive antibiotics 4 hours before birth and ß-lactam antibiotic-eligible) or unavoidable and to determine whether a violation of the 2010 Centers for Disease Control and Prevention (CDC) protocol (delayed or incorrect antibiotics) occurred. RESULTS: A total of 197 of 488 (40.4%, 95% confidence interval 36.1-44.8%) newborns of group B-colonized women received inadequate prophylaxis. Of these, 157 cases (79.7%, 73.4-84.8%) were unavoidable and would have occurred even with perfect protocol adherence. The 40 (20.3%, 15.3-26.5%) avoidable cases due to protocol violations resulted from delayed antibiotic administration (first dose of antibiotics more than 1 hour after admission [median 9.33 hours, range 3.83-25 hours] in 25 patients; no antibiotics in four patients; total 29 patients, 72.5%) or incorrect antibiotic selection (11 patients, 27.5%). CONCLUSIONS: Forty percent of patients received inadequate prophylaxis, and four of five cases are unavoidable with our current labor management and the 2010 CDC guidelines. Timeliness and selection of antibiotics remain areas for improvement, but the overall effects on sepsis prevention will be modest.

Perinatal High-Grade Cervical Cytology: A Case Series From a Safety Net Institution.

OBJECTIVE: To describe the outcomes of women with high-grade cervical cytology in pregnancy and to identify factors that predict completion of appropriate postpartum follow-up. METHODS: We describe a case series of all patients with high-grade cervical cytology collected during pregnancy between 2007 and 2011 at a single institution. Patients were considered adherent with follow-up if they received any kind of postpartum evaluation or treatment for their cervical dysplasia at our institution within 9 months of delivery. RESULTS: Of 138 women with high-grade cervical cytology in pregnancy, 87 (63%) had high-grade squamous intraepithelial lesion, 47 (34%) had atypical squamous cells that cannot rule out high-grade (ASC-H), and 4 (3%) had atypical glandular cells (AGC). Most patients (81%) underwent colposcopy during pregnancy. A total of 48 patients (43%) had biopsies performed, 26 (54%) were CIN 2 or 3, and one (2%) was adenocarcinoma in situ (AIS). A total of 97 (70%) of 138 patients completed recommended postpartum follow-up, resulting in the detection of one additional case of AIS and one case of invasive adenocarcinoma. Hispanic ethnicity (odds ratio [OR], 3.6; confidence interval [CI], 1.4-9.1), being married (OR, 4.5; CI, 1.6-12.4), being employed (OR, 3.7; CI, 1.3-10.5), and CIN2 or 3 on antenatal biopsy (OR, 9.8; CI, 2.0-47.9) were all significantly associated with completion of postpartum follow-up. CONCLUSION: Colposcopy during pregnancy resulted in the detection of one case of AIS. Postpartum evaluation and treatment detected an additional case of AIS as well as one case of invasive cervical adenocarcinoma. Whereas certain demographic characteristics were associated with completion of recommended follow-up, the strongest association is with a high-grade biopsy during pregnancy.
