Published earlier this year, two UK hospices looked at the issues relating to virtual visits including clinical issues, ethical, logistical, and relating to the Covid-19 lockdown. They found a number of areas to help guide longer term service design, but concluded a one size fits all approach was a poor fit. They concluded virtual visits have great potential but not in any way a complete solution.
