Study summary

Background: Patients with suspected brain infections pose major challenges to low and middle income countries, including their disproportionately high burden, diverse causes with inadequate surveillance, requirement for invasive and expensive tests, and the difficulty of management without a clear diagnosis. This is all compounded by resource and system constraints. Few studies have attempted to improve the care of these people in resource-limited settings.

Aim: This study sets out to improve the diagnosis and early management of people with suspected acute (\<28 days of symptoms) brain infections in low and middle income countries, using a coordinated thematic approach.

Outcomes: The primary outcome will be proportion of people with suspected acute brain infection receiving a diagnosis. Secondary outcomes will include mortality, length of stay in hospital, quality of life, degree of disability, and proportion having a lumbar puncture test.

Participants: Children and adults with features consistent with an acute brain infection, including meningitis and encephalitis, will be recruited at a variety of hospitals in Brazil, India and Malawi.

Study procedures: An assessment of current practice and capabilities at each hospital, including patient and sample journey observations and interviews with healthcare staff, will identify barriers to optimal care. Using this, a sustainable pragmatic multi-component intervention will be produced, with components modifiable to each hospital's needs. Outcomes will be reassessed post-intervention.

Study population

Patients presenting to a study hospital with symptoms and/or signs suggestive of an acute brain infection.

Inclusion criteria

  1. Adults, infants and children presenting to a study hospital with symptoms and/or signs suggestive of acute brain infection, which could be suspected encephalitis, suspected meningitis, or alternative features raising suspicion of brain infection.
  2. Symptom duration of less than 4 weeks.

Exclusion criteria

Exclusion Criteria:

  1. Neonates, i.e. children under the age of 28 days.
  2. People with pre-existing indwelling ventricular devices (e.g. extra-ventricular drains, ventriculo-peritoneal shunts) or other implants in contact with the meninges or brain (e.g. deep brain stimulators).
  3. People without an indwelling device, having undergone neurosurgical procedures within the preceding 12 months.

What researchers measure

Primary outcomes

  1. Microbiological diagnosis

    Proportion of patients achieving microbiological diagnosis

    Time frame: During hospital admission, or at 30 days if participant still in hospital

  2. Syndromic diagnosis

    Proportion of patients achieving syndromic diagnosis

    Time frame: During hospital admission, or at 30 days if participant still in hospital

Secondary outcomes

  1. Proportion receiving, and time to lumbar puncture

    Proportion of study participants receiving a lumbar puncture, and time to lumbar puncture

    Time frame: During hospital admission, or at 30 days if participant still in hospital

  2. Proportion having appropriate cerebrospinal fluid investigations

    All of: cell count, total and differential; CSF protein concentration; CSF glucose concentration; paired serum/blood glucose concentration; microscopy and culture for bacteria

    Time frame: During hospital admission, or at 30 days if participant still in hospital

  3. Mortality

    All-cause

    Time frame: At 30 days

  4. Length of stay in hospital

    Duration of hospital admission

    Time frame: During hospital admission, or at 30 days if participant still in hospital

  5. Time to appropriate empirical therapy

    Time to appropriate empirical anti-infective therapy

    Time frame: During hospital admission, or at 30 days if participant still in hospital

  6. Time to appropriate definitive therapy

    Time to appropriate definitive anti-infective therapy

    Time frame: During hospital admission, or at 30 days if participant still in hospital

  7. Quality of life score

    Using EuroQol EQ-5D questionnaires scoring 5 domains at levels 1-3 each, and an overall health state from 0 to 100.

    Time frame: At hospital discharge, or at 30 days if participant still in hospital

  8. Quality of life score

    Using EuroQol EQ-5D questionnaires scoring 5 domains at levels 1-3 each, and an overall health state from 0 to 100.

    Time frame: At 30 days after presentation to hospital

  9. Liverpool Outcome Score

    Score measuring neurological function after brain infection, reporting a lowest score of 15 domains between 2 and 5, and a total score with range 33-75.

    Time frame: At hospital discharge, or at 30 days if participant still in hospital

  10. Liverpool Outcome Score

    Score measuring neurological function after brain infection, reporting a lowest score of 15 domains between 2 and 5, and a total score with range 33-75.
