A total of 1252 workers from 21 enterprises were surveyed by means of questionnaires. The survey uncovered grave shortcomings in the delivery of medical care at all levels. In particular, only 58.2 per cent of the interviewed were satisfied with the work of feldshers providing medical care at health posts. An analysis was also made of workers' suggestions regarding the work of shop physicians, chiefs of health units, administration, public organisations at enterprises and their working collectives.
