cx est, cxest = (number of elective surgeries/number of facilities reporting elective surgeries) * (number of facilities reporting enabled elective wards). hrcx, hrcx = total hours occupied in elective surgeries/cxest.. tothabilest, tothabilest = (effective working hours in institutions reporting ward * institutions reporting surgeries)/(institutions reporting staffed wards). hrhabilest: year, hrhabilest = tothabilest/enabled wards/ working days per year.
