This dataset assesses the efficacy of Chloe SED®, a novel device for administering analgesia during manual vacuum aspiration (MVA), through a multisite, randomized controlled non-inferiority trial aimed at comparing its effectiveness to the standard spinal needle in providing humane care for abortion or miscarriage procedures in low-resource Kenyan healthcare settings. Data captures patient pain tolerance and experiences with Chloe SED® versus the spinal needle, gestational age, prior MVA experiences, reasons for MVA, as well as healthcare providers’ perceptions of pain control and their experience with MVA procedures. The dataset enables a comprehensive comparison of pain control outcomes between Chloe SED® and the standard method, providing insight into the device's potential for improving care quality.
