Ucyigit A, et al. - Researchers here examined how the Ambulatory Hyperemesis Unit at an inner-city teaching hospital since its establishment in 2012 has influenced the inpatient admission rate and length of stay for hyperemesis gravidarum. In addition, they sought to provide an estimate of the financial impact of this service on the hospital trust. At King’s College Hospital, London, they conducted a retrospective observational analysis, spanning a 12 year period. They analyzed data obtained from the admissions database, both before and after the unit opened. Findings suggest despite of no effect on the total number of inpatient admissions following establishment of the outpatient services, there were significant reductions in the length of stay per patient admission and total number of inpatient nights per year. This benefit is sustained over many years, and is probably because of the focused and accessible aftercare the ambulatory hyperemesis unit gives. This resulted in a substantial estimated cost-saving to the hospital trust, of almost £100,000 per year.
