This guide breaks down the Bacterial Meningitis Score—a lifesaving tool that aids in quick decision-making for children’s care—into clear, manageable information you can trust.

Understanding Bacterial Meningitis

Bacterial meningitis is a serious infection. It happens when bacteria get into the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord. This disease can hurt or even kill quickly, so doctors need to find it fast.

Signs of bacterial meningitis in kids include fever, headache, stiff neck, and feeling very tired.

There are many types of bacteria that can cause this illness. Streptococcus pneumoniae and Neisseria meningitidis are common culprits. Babies might get sick from group B streptococcus or Haemophilus influenzae type b, but there are vaccines for these now.

Doctors use tests like lumbar punctures to look at CSF and find out if someone has bacterial meningitis. They check for things like CSF protein, glucose levels, and white blood cells.

The right antibiotics can treat the infection if given quickly enough; without them, there could be big problems like hearing loss or learning difficulties later on.

Getting sick with bacterial meningitis is scary because it’s such a critical illness. But knowing about it—how to spot it, what causes it, how doctors diagnose and treat it—helps protect everyone’s health better.

The Bacterial Meningitis Score for Children

Navigating the complexities of diagnosing bacterial meningitis in children, medical professionals have devised a crucial tool — the Bacterial Meningitis Score. This evidence-based scoring system aids physicians in distinguishing bacterial from viral meningitis with greater precision, optimizing patient care and reducing unnecessary antibiotic use.

Purpose And Function

Doctors use the Bacterial Meningitis Score to quickly tell if a child might have bacterial meningitis. It helps them decide fast because this illness can harm kids quickly without the right treatment.

The score looks at different signs and lab results, like how severe the fever is or what’s found in blood tests.

This tool is great for preventing unnecessary antibiotics. It means fewer kids get medicine they don’t need. This reduces the chance of side effects and fights antibiotic resistance.

So, it’s not just good for one sick kid—it helps keep all of us healthier in the long run.

Definition And Calculation

Understanding how the Bacterial Meningitis Score (BMS) works is vital for its correct use. Here is what you need to know about defining and calculating this score:

  • The BMS is a clinical prediction rule developed to identify the risk of bacterial meningitis in children.
  • To calculate the score, doctors look at five key signs that point towards bacterial infection.
  1. Check for seizure activity.
  • If a child has experienced seizures, this counts towards the BMS.
  1. Look at blood test results.
  • Doctors examine blood work for an elevated absolute neutrophil count (ANC).
  • They also check if procalcitonin levels are high, as this can indicate serious bacterial infections.
  1. Study findings from cerebrospinal fluid (CSF).
  • CSF Gram stain that shows bacteria is a major red flag for bacterial meningitis.
  • Low CSF glucose levels compared to blood glucose levels suggest a bacterial cause.
  • CSF pleocytosis or high white blood cell count in spinal fluid adds to the score.
  1. Consider other tests.
  • A positive result on a blood culture signals possible bloodstream infections linked with meningitis.
  1. Add up points from each finding:
  • Each of these factors earns points on the BMS scale.
  • Higher total scores indicate a greater likelihood of bacterial meningitis.
  1. Use thresholds set by medical experts:
  • Specific point totals guide doctors on whether they should treat suspected cases aggressively with antibiotics or not.
  1. Match findings against criteria:
  • Clinicians compare their scoring against established benchmarks to determine the next steps in treatment or further testing.

Limitations and Exclusion Criteria of the Bacterial Meningitis Score

The Bacterial Meningitis Score is not perfect. Sometimes it misses cases, especially in certain children. These kids might have other infections like Lyme disease or viral encephalitis that show similar signs.

Doctors do not use the score for newborns or babies younger than 29 days old because their symptoms and risks are different.

Also, children who have had a VP shunt placed for hydrocephalus may not get accurate results from this score. Kids with recent head trauma, those taking strong antibiotics already, or those with serious diseases that affect the brain can’t rely on this tool either.

The test doesn’t always work well if someone has an immune system problem or has just had a seizure.


Question: Why Do Doctors Use Blood Cultures In The Score?

Doctors test blood cultures to see if bacteria from meningitis have spread into the bloodstream—this shows how serious the infection might be.

Question: Can We Prevent Some Types Of Bacterial Meningitis In Children?

Yes, kids can get vaccines like Hib vaccine and conjugate vaccines to prevent certain bad germs that cause meningitis, like H. influenzae type b and N. meningitidis.

Question: How Does Antibiotic Therapy Fit Into Treating Bacterial Meningitis?

If a doctor thinks it’s bacterial meningitis, they start antibiotic therapy right away to fight off germs like streptococcus spp and stop them quickly before they cause more harm.

Question: What Happens If We Use Antibiotics Too Much For Viral Infections?

Using antibiotics when not needed can lead to antibiotic overuse which makes bacteria stronger and resistant — so it’s important only to use them for bacterial infections!

Question: Are There Any Side Effects Of Treating Bacterial Meningitis In Children?

Treating this kind of sickness often involves strong medicines that come with risks—kids may face adverse effects or problems like epilepsy—but getting care early on helps lower these risks.


Doctors have a critical job: spotting bacterial meningitis in kids fast. That’s where the Bacterial Meningitis Score helps out. With this tool, they can act quickly and save lives.

It’s smart to keep track of new rules or updates—they make diagnosing even better! Remember, using the score right could mean less guesswork and stronger care for our children. Use the Bacterial calculator wisely, if you still have issues then let us know in the comments below!
