response: SELECT AVG(intakeoutput.cellvaluenumeric) FROM intakeoutput WHERE intakeoutput.patientunitstayid IN (SELECT patient.patientunitstayid FROM patient WHERE patient.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.uniquepid = '015-91239') AND patient.unitdischargetime IS NULL) AND intakeoutput.celllabel = 'urinary catheter output: indwelling/continuous ure' AND intakeoutput.cellpath LIKE '%output%' GROUP BY STRFTIME('%y-%m-%d', intakeoutput.intakeoutputtime)
