A confidential consultation is the essence of family practice. That co
nfidentiality is currently under attack from a number of disruptive in

fits of each of these is analysed to elucidate why they have been allo
wed into consultations. Their drawbacks in the light of current publis
hed evidence is presented. Conditions which make intrusions permissibl
e are proposed and practical suggestions are made about how to minimis
e their impact.
