This manual is arranged by symptoms (e.g. vaginal bleeding in early pregnancy). Because this symptom-based approach is different from most medical texts, which are arranged by disease, a corresponding diagnosis table is provided. Links have been used extensively to facilitate navigation between symptoms and diagnoses. The clinical action steps are based on clinical assessment with limited reliance on laboratory or other tests and most can be performed in a variety of clinical settings (e.g. district hospital or health centre).
