How to manage meningitis?
To improve patient outcomes, it is best managed by an interprofessional team that includes an infectious disease expert, emergency department physician, laboratory professional, internist, nurse practitioner, and a pediatrician. The key is to start prompt treatment without delay. One should not wait for cultures if suspicion is high of meningitis. The infectious disease specialist should consult with a board-certified infectious disease pharmacist so optimal antimicrobial therapy based on the latest antibiogram data can be initiate empirically, enhancing the chance for successful treatment. These patients need inpatient treatment until all symptoms have disappeared, therefore the nursing staff will be responsible for administration as well as monitoring for therapeutic effectiveness and adverse drug events, reporting any concerns to the team. The outlook for patients with delayed diagnosis or treatment is poor. More important, delays also lead to litigation. [16][17]
What is the CSF for meningitis?
The CSF should be sent for Gram stain, culture, complete cell count (CBC), and glucose and protein levels. Bacterial meningitis typically results in low glucose and high protein levels in the cerebrospinal fluid. As CSF glucose levels are dependent on circulating serum glucose levels, the CSF to serum glucose ratio is considered more reliable parameter for the diagnosis of acute bacterial meningitis than absolute CSF glucose levels. A neutrophil predominance on cell count would be expected.

What to do before lumbar puncture?
The diagnosis would be confirmed with bacteria identified on gram stain or culture. A non-contrast CT scan of the head should be performed before lumbar puncture if the patient has a risk of herniation. Risk factors include papilledema on the exam, new onset seizures, focal neurologic deficits, or is immunocompromised. Consider delaying the lumbar puncture if the patient has unstable vital signs, coagulation abnormalities, or has had a recent seizure. Treat with antibiotics empirically if testing is going to be delayed. Blood cultures should be obtained as 53% of patients have concurrent bacteremia. Elevated C-reactive protein or procalcitonin levels would suggest a bacterial rather than viral etiology. [10][11][12]

Is meningitis more common in children?
Bacterial meningitis was previously more common in pediatric patients. However, as vaccines are developed and utilized, the prevalence of acute bacterial meningitis has decreased and the epidemiology of causative microorganisms has changed. Vaccinations have increased the median age of patients infected. In 2006 there were 72,000 meningitis-related hospitalizations in the United States. The majority of these cases were due to viral infection (54.6%). Bacterial infections accounted for 21.8% of cases, and 7.3% were due to fungi and parasite infections, while 17.2% were due to an unspecified cause. There was an 8% in-hospital mortality rate for patients with bacterial meningitis, and it rose substantially for patients older than 45. [7][8][9] The annual incidence of meningitis in the United States decreased from 2.00 cases per 100,000 population in 1998–1999 to 1.38 cases per 100,000 population in 2006–2007 while the median age of patients increased from 30.3 years in 1998–1999 to 41.9 years in 2006–2007.[4] As per CDC data, rates of meningococcal disease have been declining in the United States since the late 1990s. In 2017, there were about 350 total cases of meningococcal disease reported (incidence rate of 0.11 cases per 100,000 persons).
