"Sound Diagnosis" to the rescue – a little prompt at the bedside, when you need sound guidance to see through a hazy clinical picture and make sense of a problem in the most lucid and confident way. How will you benefit from this diagnosticum? As your bedside companion it will: shed bright light on unclarified diagnostic pictures; encourage use of a systematic method of diagnosis; structure and simplify diagnosis; help you define a problem; make you notice and respond to diagnostic key pointers; direct your energies to the core of the problem; give your knowledge an opportunity to surface; make you more aware and open to reading signs of disease; serve as a ward-round guide; keep you fresh and motivated with each case; and, tie up the loose ends, enabling you to complete a diagnosis.
