			'''The “Point prevalence survey of healthcare-associated infections and antimicrobial use in European acute care hospitals” protocol adopts the following definition of Central Nervous System Infection (CNS).'''

			'''CNS-IC: intracranial infection (brain abscess, subdural or epidural infection, encephalitis).'''

			;Intracranial infection must meet at least one of the following criteria:
			:* patient has organisms cultured from brain tissue or dura;
			:* patient has an abscess or evidence of intracranial infection seen during a surgical operation or histopathologic examination;
			:* patient has at least two of the following signs or symptoms with no other recognised cause: headache,
			:* dizziness, fever (> 38 °C), localising neurologic signs, changing level of consciousness, or confusion,
			:and at least one of the following:
			:* organisms seen on microscopic examination of brain or abscess tissue obtained by needle aspiration or by biopsy during a surgical operation or autopsy;
			:* positive antigen test on blood or urine;
			:* radiographic evidence of infection, e.g. abnormal findings on ultrasound, CT scan, MRI, radionuclide brain scan, or arteriogram;
			:* diagnostic single antibody titre (IgM) or fourfold increase in paired sera (IgG) for pathogen
			:and
			:* if the diagnosis is made antemortem, the physician institutes appropriate antimicrobial therapy.
			:* if meningitis and a brain abscess are present together, the infection must be reported as CNS-IC.



			'''CNS-MEN: meningitis or ventriculitis.'''

			;Meningitis or ventriculitis must meet at least one of the following criteria:
			:* patient has organisms cultured from cerebrospinal fluid (CSF);
			:* patient has at least one of the following signs or symptoms with no other recognised cause:
			:* fever (> 38 °C), headache, stiff neck, meningeal signs, cranial nerve signs, or irritability,
			:and at least one of the following:
			:* increased white cells, elevated protein, and/or decreased glucose in CSF;
			:* organisms seen on Gram’s stain of CSF;
			:* organisms cultured from blood;
			:* positive antigen test of CSF, blood, or urine;
			:* diagnostic single antibody titre (IgM) or fourfold increase in paired sera (IgG) for pathogen
			:and
			:* if the diagnosis is made antemortem, the physician institutes appropriate antimicrobial therapy.

			Further instructions for reporting:
			* CSF shunt infection must be reported as SSI-O if it occurs <=1 year of placement; if later or after manipulation/access of the shunt, report as CNS-MEN;
			* meningoencephalitis must be reported as CNS-MEN;
			* spinal abscess with meningitis must be reported as CNS-MEN.


			'''CNS-SA: spinal abscess without meningitis.'''

			;An abscess of the spinal epidural or subdural space, without the involvement of the cerebrospinal fluid or adjacent bone structures, must meet at least one of the following criteria:
			:* patient has organisms cultured from an abscess in the spinal epidural or subdural space;
			:* patient has an abscess in the spinal epidural or subdural space seen during a surgical operation or at autopsy or evidence of an abscess seen during a histopathologic examination;
			:* patient has at least one of the following signs or symptoms with no other recognised cause: fever (> 38 °C), back pain, focal tenderness, radiculitis, paraparesis, or paraplegia,
			:and at least one of the following:
			:* organisms cultured from blood;
			:* radiographic evidence of a spinal abscess, e.g. abnormal findings on myelography, ultrasound, CT scan, MRI, or other scans (gallium, technetium, etc.);
			:and
			:* if the diagnosis is made antemortem, the physician institutes appropriate antimicrobial therapy.
			:* Spinal abscess with meningitis must be reported as meningitis.
