- Brief Summary
Labor induction is one of the most common obstetric procedures performed in the U.S. In 2012, the last year for which data is available, 23.7% of all deliveries were the result of inductions. Labor induction first requires cervical ripening, which can be accomplished by several different methods. Vaginal or oral prostaglandins, extra amniotic saline infusion, osmotic dilators and transcervical Foley catheters are all widely used instruments for pre-induction cervical ripening. The ideal cervical ripening tool is safe for both mother and fetus, incurs low cost, does not require extensive monitoring, and causes minimal maternal discomfort. The Foley catheter has been found to be both safe and effective, but little is known about patient satisfaction with the device in an in-patient and out-patient setting. The proposed study will investigate patient satisfaction in a randomized controlled trial of in-patient versus out-patient use of Foley catheters.
- Detailed Description
Labor induction is one of the most common obstetric procedures performed in the U.S. In 2013, the last year for which data is available, 23.1% of all deliveries were the result of inductions. Labor induction often first requires cervical ripening, which can be accomplished by several different methods.
Pharmacologic cervical ripening approaches include vaginal or oral prostaglandin administration. Mechanical cervical ripening methods include osmotic dilators such as laminaria, and transcervical Foley catheters with or without extra amniotic saline infusion. The ideal cervical ripening tool is effective, safe for both mother and fetus, incurs low cost, does not require extensive monitoring, and causes minimal maternal discomfort.
Several recent meta-analyses have demonstrated both the safety and efficacy of the Foley catheter for pre-induction cervical ripening. When compared to prostaglandins, studies have shown that use of the transcervical Foley catheter for pre-induction cervical ripening results in either shortened or no statistically significant difference in vaginal delivery rates at 24 hours. No studies have demonstrated longer duration to vaginal delivery and cesarean delivery rates are equivalent. In addition, women with Foley catheters experience less uterine hyper-stimulation resulting in fetal heart rate changes as compared to those who receive prostaglandins. Other than one study suggesting increased risks of chorioamnionitis and neonatal infection, the vast majority of research suggests Foley catheters are overwhelming safe with little risk of severe maternal or neonatal morbidity.
Due to its safety profile and the ongoing desire to reduce healthcare costs, many institutions have initiated outpatient cervical ripening protocols. Studies suggest that outpatient cervical ripening with transcervical Foley catheter is both safe and effective. In addition, some studies demonstrate women who underwent outpatient cervical ripening spent less time in the hospital during their labor induction, sometimes resulting in significant cost savings at those institutions. The combination of safety, ease of use and cost savings potential make outpatient cervical ripening with a Foley catheter an appealing tool for both clinicians and patients. However, data on patient satisfaction with almost all methods of cervical ripening is sparse. Existing data on patient satisfaction of outpatient versus inpatient induction of labor stems from prior studies which used vaginal misoprostol gel or isosorbide mononitrate as induction agents. While one study suggests overall satisfaction with outpatient Foley catheter cervical ripening, a randomized controlled trial on this topic has yet to be performed.

Group Intervention Description Inpatient Inpatient Cervical Ripening Subjects randomized to this group will receive the same intervention as the outpatient group -- cervical ripening with Foley catheter -- but remain within the hospital. Subjects will be asked to complete a survey assessing their fears, opinions, anxiety, satisfaction and hours of sleep before and after the catheter is placed and removed, respectively. The intervention: randomization to inpatient cervical ripening Inpatient Foley catheter placement Subjects randomized to this group will receive the same intervention as the outpatient group -- cervical ripening with Foley catheter -- but remain within the hospital. Subjects will be asked to complete a survey assessing their fears, opinions, anxiety, satisfaction and hours of sleep before and after the catheter is placed and removed, respectively. The intervention: randomization to inpatient cervical ripening Outpatient Outpatient Cervical Ripening Subjects randomized to this group will receive the same intervention as the inpatient group -- cervical ripening with Foley catheter -- but will be discharged home. Subjects will be asked to return to the hospital when the catheter falls out or if 24 hours has elapsed. They will be given detailed instructions and provided a 24 hour phone number to call should they have any concerns.

- Primary Outcome Measures
Name Time Method Patient satisfaction scores Through study completion - expected to be one year The primary outcome will be the total score on Part A of the survey, giving an overall rating of the patients' experience with treatment. Means and standard deviations of the total score will be calculated and reported by treatment group among nulliparous and multiparous patients separately. To address the main hypothesis, an ANOVA (analysis-of-variance) will be performed on an intention-to-treat basis and the stratum (nulliparous vs multiparous) will be controlled for in the analysis. The mean difference between treatment groups will be calculated and reported with a 95% confidence interval for the population difference. A two-sample t-test will be used to test for a significant difference in overall rating between in-patient versus out-patient treatment groups.
- Secondary Outcome Measures
Name Time Method Multiparous versus Nulliparous subjects Through study completion - expected to be one year Mean differences between in-patient and out-patient treatment will be calculated and reported with 95% confidence intervals among nulliparous and multiparous patients separately. An ANOVA test of interaction will be made in order to address whether multiparous patients rate their experience with the Foley catheter differently than do nulliparous patients.
