What the study found
The review identified 21 unique numerical scoring systems for diagnosing tuberculous meningitis (TBM), a severe form of tuberculosis affecting the brain and surrounding tissues. Of these, 4 scoring systems had been externally validated.
Why the authors say this matters
The authors conclude that Thwaites (2002) and Marais (2010) may be useful as first-line TBM screening tests because of their high sensitivities and extensive external validation. They also say clinicians should consider scores that fit their patient population.
What the researchers tested
The researchers conducted a systematic review by searching PubMed and EMBASE from inception to 21 March 2024. They included cross-sectional studies with numerical TBM scoring systems and excluded non-human studies, single diagnostic tests, papers without a gold standard diagnosis, and non-English papers.
What worked and what didn't
The review described the features of the identified scores, including clinical, laboratory, microbiological, histopathological, and radiological criteria, as well as their interpretation. It also summarized sensitivity, specificity, and study population details. The abstract states that only 4 of the 21 scores had external validation.
What to keep in mind
The abstract does not provide the detailed sensitivity and specificity values for each score. It also notes that clinicians should consider scores specific to their patient population, which suggests performance may vary by setting.
Key points
- Tuberculous meningitis is described as a severe extrapulmonary complication of tuberculosis.
- The review found 21 unique numerical TBM scoring systems.
- Only 4 of those scoring systems had external validation.
- Thwaites (2002) and Marais (2010) are suggested as first-line screening tests.
- The authors advise considering patient-population-specific scores.
