The Calda class utility hospital is a vital structure present on colonies of the Romulan Star Empire. They, however, seem to have more in common with a vehicular production yard then a hospital.
This is because of the Romulan belief that an injured colonist does not contribute to the colony and, thus, must be treated enough for them to work again. That is the purpose of the Calda class utility hospital which is to heal, treat and mend wounds to the extent that will allow a colonist to be physically functional.
This ensures that the Calda utility hospital has all the basic, general medical facilities for a quick rapid treatment of wounded. Many of the treatments are extreme and quite ethically questionable but this does not deter its use on Romulan worlds. Several upgrades are available that improve the facilities use on the planet.
