Vaginal birth after cesarean delivery: an historic cohort cost analysis.

OBJECTIVE: The purpose of this study was to evaluate the relative cost-effectiveness of attempted vaginal birth after cesarean delivery compared with elective repeat cesarean delivery. STUDY DESIGN: We performed an historic cohort analysis of women with a single prior cesarean delivery who were delivered at our institution during 1999. Inclusion criteria were > or =36 weeks' gestation and carrying a live, singleton fetus with no antenatally diagnosed anomalies. The primary outcome variable was mean cost of hospital care for mother-infant pairs, as obtained from the hospital's Clinical Resources Department. RESULTS: The cohort consisted of 204 mother-infant pairs, 65 in the elective repeat cesarean group and 139 in the attempted vaginal birth group. Mean cost of care was higher for mothers ($4155 vs $3675;P <.001), neonates ($1794 vs $1187; P =.03), and mother-infant pairs ($5949 vs $4863; P =.001) for the elective repeat cesarean group compared with the attempted vaginal delivery group. CONCLUSION: In women with a single prior cesarean delivery, a trial of labor is more cost-effective than an elective repeat cesarean delivery.

Antimicrobial susceptibility of Gram-negative uropathogens isolated from obstetric patients.

OBJECTIVE: To evaluate the antimicrobial susceptibility of Gram-negative uropathogens isolated from pregnant women. METHODS: We performed a snapshot cohort study of women receiving care in the University of Florida prenatal clinics during March 2000. Subjects with asymptomatic bacteriuria or cystitis were identified and the antimicrobial susceptibility of each pathogen was recorded. Data were analyzed using chi-square, Fisher's exact test and ninety-five percent confidence intervals, as appropriate. RESULTS: Ninety-five positive cultures were identified. Isolates were more often susceptible to trimethoprim-sulfamethoxazole (TMP-SMX) (87%) and nitrofurantoin (89%) than to ampicillin (72%) (p < 0.03). Escherichia coli accounted for 71 (75%) cases and was more often susceptible to nitrofurantoin (100%) than to TMP-SMX (87%) (p < 0.01). Proteus isolates were all susceptible to TMP-SMX and resistant to nitrofurantoin (p < 0.01). CONCLUSIONS: Both TMP-SMX and nitrofurantoin are superior to ampicillin for empiric treatment of lower urinary tract infection in pregnant women. Nitrofurantoin is superior to TMP-SMX for treatment of infections caused by E. coli. For suspected or confirmed cases caused by Proteus organisms, TMP-SMX is the preferred agent.
