Here is what my MacBook dictionary gives for the word CLINICAL.

clinical | ˈklɪnɪkl | adjective

1 relating to the observation and treatment of actual patients rather than theoretical or laboratory studies: clinical medicine | clinical drug trials. • (of a disease or condition) causing observable and recognizable symptoms: clinical depression. 

2 very efficient and without feeling; coldly detached: nothing was left to chance—everything was clinical. • (of a room or building) bare, functional, and clean: the room was white and clinical. ORIGIN late 18th century: from Greek klinikē ‘bedside’ (see clinic) + -al.

And in the design of its Founder-Acarya, His Divine Grace A.C. Bhaktivedanta Swami Prabhupada, ISKCON temples are meant to be the “clinics”, where the medicine of

and the diet of Krishna prasadam (sanctified food ) are administered for the best healing chances of all patients.

This can also be done anywhere else indeed, provided the participants have proper Krishna conscious information as to the processes to follow. Best is the get proper information from Srila Prabhupada Himself in his His books or from His representatives, whom He has thoroughly trained over the years.
