"Why must my granddaughter wait?"

Recently, my granddaughter unfortunately lost her baby so had to go to hospital, and was told to go back the following Sunday for a scan. She waited and waited only to be told that nobody had booked a scan, the Dr that was there on Sunday was very good with her but at the end of the day she had just lost her baby and she now has to go back again for her scan. Surely this is far too long? I would like to know why when we have a perfectly good hospital in High Wycombe we can't use it. Stoke Mandeville is obviously over stretched and some thing needs to be done to address this.
