Demanding immediate intervention by the police, a spokesman of the association said, "We did not block any OPD. We did not resort to trade unionism, we did not ask our members to stop work, but our members responded by not attending OPDs."
"This is against increasing attacks on members of medical fraternity in the city, vandalisation of properties and refusal to pay bill for medical treatment," he said adding that over 4000 doctors affiliated to the association stayed away from OPDs in around 10 private hospitals.
The cease work was triggered by alleged intimidation by relatives of a patient at CMRI Hospital last week who had refused to pay the hospital bill amounting to Rs 75,000 for a patient under treatment for one month.
The agitating doctors, however, assured emergency services and claimed care of admitted patients "were not affected".
The protesting doctors expressed "complete solidarity with their CMRI colleagues".
An Indian Medical Association (IMA) official said, "We do not support any strike in medical establishments. We support the recent bill introduced by the state government aimed at improving facilities at the private health care sector but we also oppose hooliganism."
Mr Saibal Biswas, a Bangladeshi patient was furious after finding no doctor at an OPD at a private super specialty hospital off E M Bypass and said, "Why should patients suffer! I had prior appointment today but as I called my doctor he advised me to come next week."
Members of another patients' family said doctors can't go on agitation in this way, after running from one private hospital to another, finally finding a doctor at a third hospital.
