BACKGROUND: The diagnostic and treatment approaches for schistosomiasis in individual patients, outside endemic areas, are not standardised. This study aimed to appraise the reference documents that the experts from the TropNet and GeoSentinel networks use in practice as guidance for the clinical management of their patients with (suspect) schistosomiasis. METHODS: We systematically appraised the following data from the referenced guidance documents: i) document type, ii) case definitions, iii) diagnostic techniques envisaged
iv) treatment recommendations
v) follow-up recommendations
vi) screening recommendations, and vii) symptom-based diagnostic suspicion. RESULTS: Twenty-two of the 30 responders (73.3%) indicated 19 reference documents, three of which were WHO material not intended for individual clinical management. Only 4/19 (21.1%) documents were national recommendations
no international guideline was indicated. Case definitions were explicitly presented in only one document (1/19
5.3%). Diagnostic tools were detailed in 11/16 (68.8%) and follow-up guidance in 8/16 (50%) documents. Treatment guidance was provided in 14/16 (87.5%) documents. CONCLUSIONS: Heterogeneity in clinical guidance was evident, although with noticeable overlap at least for chronic schistosomiasis. This confirms the need to formalise case definitions, which should be used to design trials to rigorously assess diagnostic tools and treatment schemes, and eventually come to harmonisation of clinical management guidance.
