Antibiotics and developments of physical therapy following the two world wars put paid to the formalised notion of 'convalescence' in the UK, the elimination of TB as an endemic disease was the effective end of the convalescent sanatorium: Sanatorium - from the first to the last .
Social change has also played a role, a wealthier society has meant that home for most people is a far more comfortable place that any institution and there's the additional influence of the failure of the 'mental health sanatoria' in the 1950s and 60s which led to the default position of 'care in the community'.
The one area that does still have some convalescent provision in the NHS is post cancer surgery, mostly for frail older patients.
Institutional change should not of course have necessarily led to the the abandonment of the notion of 'convalescence' but connotations of passivity and entitlement have probably led to it becoming a less acceptable term.
