Purpose: To audit telephone calls concerning general issues in communi
cable disease control and environmental health to a department of publ
ic health medicine. Setting: A department of public health medicine in
a district with a population of 190000 during 1993. Method: A retrosp
ective audit of forms designed to record all calls concerning environm
ental health and communicable disease control. The intervention was a
change in design of forms and education of doctors dealing with the ca
lls. A re-audit was done after these changes had been implemented. Res
ults: The number of recorded calls increased from 1.75 (1992) to 3.29
(mid-1993) per week. Signing of forms increased from 61% to 83% and da
ting from 6% to 72%. All forms filled in by registrars or senior regis
trars were reviewed by the Consultant in Communicable Disease Control
(CCDC). Very few calls were considered to be inappropriate. Discussion
: The increase in the number of calls was probably artefactual owing t
o better recording as a result of the audit. Improved recording will h
elp in future training and audit, and be a medico-legal safeguard.
