Abstract:
Objective:To take a broad overview of the current allocation of diagnosis and treatment resources and management for patients with tuberculous meningitis (TBM) in 49 hospitals in China.Methods:A cross-sectional survey about TBM was carried out in 49 hospitals from 27 provinces across China, by means of electronic questionnaire.The electronic questionnaire was filled by doctors in charge of the departments where TBM patients were routinely admitted from September to December 2018. The availability of medical resources, diagnosis, evaluation, treatment and surveillance in these hospitals were analyzed from the questionnaire. The count data were expressed as percentage.Results:Among the 49 participating hospitals, 37(75.5%) hospitals had less than 50 admissions of suspected TBM per year. Less than 20 TBM patients were confirmed by etiological diagnosis per year in 42(85.7%) participating hospitals.The availability of conventional medical imaging including computed tomography (CT), magnetic resonance imaging (MRI), enhanced MRI, cerebral angiography and magnetic resonance angiography (MRA) were 100.00%(49/49), 95.92%(47/49), 91.84%(45/49), 61.22%(30/49) and 67.35%(33/49), respectively. The rate of access to classic etiological diagnostic methods including acid-fast bacilli smear, mycobacterial culture and T cell spot test of tuberculosis infection were 77.55%(38/49), 95.92%(47/49) and 83.67%(41/49), respectively. Rifampin (100.0%, 49/49), isoniazid (100.0%, 49/49), pyrazinamide (98.0%, 48/49) and ethambutol (95.9%, 47/49) were most commonly used in initial anti-tuberculosis treatment of non-severe patients with TBM. The course of anti-tuberculosis treatment was 18 months in 25(51.0%) hospitals, and 12 months in 17(34.7%) hospitals. Intrathecal glucocorticoid and isoniazid were used in 39(79.6%) hospitals. Dexamethasone was used as part of treatment in 24(49.0%) hospitals, and the duration of glucocorticoid was about two months in 28(57.1%) hospitals. As for hyponatremia, 32(65.3%) hospitals didn′t investigate the cause, and hypertonic saline (83.7%, 41/49) and oral rehydration salts (71.4%, 35/49) were considered as the most common treatment strategy. Lumbar puncture was most commonly used for intracranial pressure surveillance in 48(98.0%) hospitals.Conclusions:The TBM cases admitted to the investigation hospitals are characterized by scattered sources and few confirmed cases of etiology. There are obvious heterogeneities in the diagnosis and treatment of TBM and the management of complications.The standardized plan for diagnosis and treatment of TBM are needed to improve the management.
