Healthcare attracts family capital for good reasons. Demand is structural rather than cyclical, the asset is defensive in a downturn, and for many families there is a genuine wish to own something that does obvious good.
It is also the most regulated thing you can buy. A hospital carries clinical licensing, biomedical waste authorisation, radiology and radiation clearances, pharmacy licensing, fire and building compliance, and empanelment relationships with insurers and government schemes that may or may not survive a change of ownership.
The commercial diligence and the clinical diligence cannot be run separately, because in healthcare they are the same question. A hospital's revenue is a function of which doctors practise there, and doctors are not assets that transfer with a share purchase agreement.
