in diagnosing bacterial meningitis?</p><div id="niceng240er5.s1.1.1"><h4>Introduction</h4><p>Bacterial meningitis is a rare but serious infection, which can occur in any age group. Early recognition of the condition requires a high index of suspicion.</p><p>Accurately diagnosing bacterial meningitis in a timely manner ensures that appropriate antibiotic therapy can be initiated, and subsequently adjusted according to the bacterial aetiology and antibiotic sensitivity results. There are a number of tests that may be used to assist in the diagnosis of bacterial meningitis. It is therefore important to determine which tests are the most accurate and cost-effective for use in clinical practice.</p><p>The aim of this review (B1) is to evaluate these tests and determine which are the most effective for the diagnosis of bacterial meningitis.</p></div><div id="niceng240er5.s1.1.2"><h4>Summary of the protocol</h4><p>See <a href="/books/NBK604179/table/niceng240er5.tab1/?report=objectonly" target="object" rid-ob="figobniceng240er5tab1">Table 1</a> for a summary of the Population, Index tests, Reference standard and Target condition characteristics of this review.</p><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figniceng240er5tab1"><a href="/books/NBK604179/table/niceng240er5.tab1/?report=objectonly" target="object" title="Table 1" class="img_link icnblk_img" rid-ob="figobniceng240er5tab1"><img class="small-thumb" src="/corehtml/pmc/css/bookshelf/2.26/img/table-icon.gif" alt="Table Icon" /></a><div class="icnblk_cntnt"><h4 id="niceng240er5.tab1"><a href="/books/NBK604179/table/niceng240er5.tab1/?report=objectonly" target="object" rid-ob="figobniceng240er5tab1">Table 1</a></h4><p class="float-caption no_bottom_margin">Summary of the protocol. </p></div></div><p>For further details see the review protocol in <a href="#niceng240er5.appa">appendix A</a>.</p></div><div id="niceng240er5.s1.1.3"><h4>Methods and process</h4><p>This evidence review was developed using the methods and process described in <a href="https://www.nice.org.uk/process/pmg20/chapter/introduction-and-overview" ref="pagearea=body&amp;targetsite=external&amp;targetcat=link&amp;targettype=uri">Developing NICE guidelines: the manual</a>.

Thresholds ranged from 0.12 ng/ml to 2.13 ng/ml, with the majority of studies using a threshold of 0.5ng/ml.</p></div><div id="niceng240er5.s1.1.6.5"><h5>Polymerase chain reaction (PCR)</h5><p>Overall, polymerase chain reaction (PCR) for N. meningitides, S. pneumonia, and H. influenzae was highly specific and moderately to highly sensitive in an undefined age. PCR for S. pneumonia in babies and children was very sensitive and moderately specific.

They considered the impact of true positives (correctly identifying bacterial meningitis and starting the appropriate management), true negatives (reassuring patients and carers that the person does not have bacterial meningitis), false positives (potentially promoting further investigations that are unnecessary, such as lumbar puncture, or starting unnecessary treatments) and false negatives (failing to identify people that require further interventions and intensive management) and noted that false negatives could be particularly impactful as they could lead to treatment being delayed until condition worsens, which would likely result in worse outcomes for the person affected &#x02013; hence a particular need to focus on the sensitivity of tests. The committee considered the positive and negative predictive values as additional information alongside sensitivity and specificity to allow them to understand what the impact of a system that recommended a certain action for all positive or negative test results would have.</p></div><div id="niceng240er5.s1.1.9.2"><h5>The quality of the evidence</h5><p>The quality of the evidence was assessed with GRADE and was rated as high to very low. Generally, evidence was downgraded due to imprecision of effect estimates (95% confidence intervals crossing decision making thresholds) and risk of bias (for example, non-consecutive patient selection, lack of details on population, two-gate study design, lack of information about whether thresholds for index tests were pre-specified, and differences between the reference standard used and the gold standard specified in the protocol). Despite there being a significant body of evidence, meta-analyses could not be conducted because of heterogeneity between studies (for example, different populations included in the studies and different criteria for diagnosing bacterial meningitis).</p><p>The committee noted that no evidence was available for urine detection of bacterial pathogens, blood culture of bacterial pathogens or any molecular diagnosis techniques apart from PCR.</p></div><div id="niceng240er5.s1.1.9.3"><h5>Benefits and harms</h5><p>The committee noted that all the evidence was based on individual blood tests and agreed that none of these blood tests alone would be sufficient to make a diagnosis of bacterial meningitis, nor should any of these tests be used to rule out bacterial meningitis. However, the committee agreed that blood tests can be an important tool when used alongside clinical features and lumbar puncture results, and these tests are simple, cheap, and widely used in current practice. The committee considered the evidence on sensitivity and specificity, together with their clinical knowledge and experience, to recommend blood tests that might support a diagnosis of bacterial meningitis.</p><p>The evidence showed that, overall, procalcitonin (PCT) was very sensitive and very specific for diagnosing bacterial meningitis in babies, children, and adults. C-reactive protein (CRP) was largely both moderately to highly sensitive and specific for a diagnosis of bacterial meningitis in babies, children, and adults. The committee discussed the higher costs associated with PCT and agreed that the difference in diagnostic accuracy was not sufficient to warrant recommending PCT over CRP. The committee therefore recommended that CRP, or PCT if CRP is not available, should be included in the blood tests performed for people with suspected bacterial meningitis.</p><p>The evidence showed that white cell count (WCC) at a threshold of greater than or equal to 15000 cells/&#x003bc;l was moderately specific for diagnosing bacterial meningitis in babies and children, although estimates of sensitivity varied they were also largely moderately sensitive. There was also some evidence from an undefined age range that abnormal WCC (either below 4000 or above 11000 cells/&#x003bc;l) was moderately sensitive (but not specific) for diagnosing meningococcal meningitis. Neutrophil count was shown to be both moderately sensitive and moderately specific for a diagnosis of bacterial meningitis in babies and children. The committee agreed that white blood cell count (including neutrophils) may be valuable to treatment decisions when considered alongside clinical presentation and could guide healthcare professionals in deciding if further investigations are required, and on this basis the committee recommended that this test should be performed.</p><p>There was limited evidence on the accuracy of polymerase chain reaction (PCR), mainly from an undefined age range. However, the evidence that was available showed that, overall, PCR for N. meningitidis, S. pneumoniae, and H. influenzae were both moderately to highly sensitive and specific for diagnosing bacterial meningitis. PCR for group B streptococcus in babies was both very sensitive and very specific. Based on the evidence, and their clinical knowledge and experience, the committee recommended that whole-blood diagnostic PCR should be included in the battery of blood tests performed. The committee agreed to give examples of PCR for meningococcal and pneumococcal as these are the more widely available tests in clinical practice, however, they did not want to restrict the recommendation to these tests as this is an area of active research and development.</p><p>There was no evidence available on the accuracy of blood culture for diagnosing bacterial meningitis. The committee agreed that it was important to specify that this should be performed as the absence of blood culture from the recommended list of tests could have the unintended consequence that this test would no longer be performed, and the committee agreed the test is important and part of routine practice. Additionally, the committee acknowledged that it is standard practice to take blood sugar and agreed to include blood glucose test to avoid situations where this test could be missed.</p><p>The committee were aware of the <u>Guidance for public health management of meningococcal disease in the UK</u>, and that meningococcal meningitis (without septicaemia) is included in this review. The committee agreed to reflect this guidance and recommend that a bacterial throat swab for meningococcal culture should be performed for people with suspected bacterial meningitis. The committee also noted that this should preferably be performed before starting antibiotics as antibiotics can affect the likelihood of obtaining a positive culture result, and that the request form should be explicit that this is specifically for meningococcal culture.</p><p>The committee also agreed that a HIV test should be performed in adults with suspected bacterial meningitis because HIV is a risk factor for serious infections. This is also in line with current practice.</p><p>No evidence was identified for urine detection of bacterial pathogens, and the committee agreed that it was not appropriate to make recommendations in this area.</p></div><div id="niceng240er5.s1.1.9.4"><h5>Cost effectiveness and resource use</h5><p>This review question was not prioritised for economic analysis and therefore the committee made a qualitative assessment of the likely cost-effectiveness of their recommendations. The committee did not think the clinical evidence was sufficiently strong to conclude that the additional costs of PCT would represent a cost-effective use of NHS resources. Therefore, they only recommended its use when CRP was not available (for example, if a local decision was made to prefer PCT over CRP, this would be acceptable, and it would not be necessary to perform both tests). The committee believed that their recommendations for investigating and diagnosing suspected meningitis are low cost and reflect current NHS practice. Therefore, the committee did not anticipate that their recommendations would result in a significant resource impact to the NHS.</p></div></div><div id="niceng240er5.s1.1.10"><h4>Recommendations supported by this evidence review</h4><p>This evidence review supports recommendations 1.4.2 to 1.4.5.</p></div></div><div id="niceng240er5.rl.r1"><h3>References - included studies</h3><ul class="simple-list"><div id="niceng240er5.rl.r1.1"><h4>Diagnostic</h4><ul class="simple-list"><li class="half_rhythm"><p><div class="bk_ref" id="niceng240er5.ref1"><p id="p-530">
