PATNA, Aug. 6 -- Resident doctors at the Patna's All India Institute of Medical Sciences (AIIMS) intensified their strike on the fifth day Tuesday by shutting the registration and billing counters, crippling hospital services, as less than 100 new patient registrations were reported at the OPD (outpatient department) against more then five times the patients registering on the Abha mobile application to avail of OPD services, said doctors on Tuesday. While new patient registrations were severely hit, around 400 patients came to the OPD for revisit, against an average daily OPD footfall of 4,000 at AIIMS, Patna. This was the first time the resident doctors forced the hospital administration to unofficially close the registration and billing counters by threatening the staff managing the counters with dire consequences. A motley group of resident doctors forced their way into the registration counters, a restricted zone, at 8.30 am on Tuesday, and asked the staff there to not do any new registration of patients, else face the music. The striking resident doctors had earlier in the day given an ultimatum to completely withdraw from OPD and emergency services from Wednesday as their demand, seeking quashing of FIR registered by RJD MLA Chetan Anand, remained unfulfilled, said a press release by the Resident Doctors Association (RDA) of AIIMS Patna on Tuesday. The number of registration of patients for OPD services has been dwindling every passing day since the resident doctors struck work from August 1, when the total OPD registration was over 2,000, which on Tuesday had come down to less than 500. The trauma and emergency wing of the AIIMS, where the ugly spat took place between the doctors, the legislator, his wife Dr Ayushi Singh and security guards, had reported only one patient admission during the last five days, when on an average around 100 patients are brought for admission in a day, and most are returned citing lack of beds. Hospital operations came to a near standstill, with outpatient services witnessing a drastic decline. OPD registrations fell by nearly 60%, with only around 1,500 patients registering on Monday compared to the usual weekday footfall of 4,000, according to doctors. In-patient admissions also suffered a 45% drop, disproportionately affecting economically disadvantaged patients who rely on the institute for affordable treatment. Emergency services were similarly affected....
