CoRONERS CONCERNS During the course of the inquest the evidence revealed matters giving rise to concern: In my opinion there is a risk that future deaths could occur unless action is taken. In the circumstances it is my statutory duty to report to you. The MATTERS OF CONCERN are as follows_ It became apparent in the course of the evidence that (1) There is a potential for Miconazole Gel to have an interaction with Warfarin such as to increase the blood clotting time and hence a higher INR reading than should be expected. This could lead to significant uncontrolled bleeding: (2) There is a significant lack of knowledge of the interaction among health professionals andlor (3) The resources available to check the interaction may not be entirely clear on this issue or readily straight forward to locate.

In my opinion action should be taken to prevent future deaths and believe your organisation has the power to take such action.
