My nearest hospital (Whittington, north London, a new build with plenty of space and a huge forecourt) has quite a few bike stands but they are almost always completely full - both sides. I suspect the vast majority of these are the staff's bikes, which is all fine, but leaves no room for visitors.
In the past I've lobbied my council to get stands installed in other locations, for example outside a re-located main post office. It was a protracted process!
