Objective: To determine general practitioner (GP) vaccination procedur
es during the first two years of implementation of the National Childh
ood Immunisation Program. Design: Two cross-sectional self-completion
mail surveys of Australian GPs, in October/November 1994 (Survey 1) an
d April/May 1996 (Survey 2). Participants: 1417 systematically selecte
d (Survey 1) and 1482 randomly selected (Survey 2) GPs. Intervention:
Mailing of a package of publications on immunisation to all GPs, a com
munity education campaign, and the introduction of the Australian Chil
dhood Immunisation Register. State and Territory and local initiatives
on immunisation, changes in vaccine distribution and funding, and med
ia coverage of vaccination issues may also have affected GPs' procedur
es. Main outcome measures: Reported vaccination procedures consistent
with National Health and Medical Research Council (NHMRC) recommendati
ons. Results: Response rates were 77% (Survey 1) and 78% (Survey 2). T
here were statistically significant rises in the proportions of GPs wh
o reported vaccination procedures consistent with NHMRC recommendation
s for simultaneous administration of vaccines, injection site, vaccina
tion of children taking antibiotics or those with mild upper respirato
ry tract infection, and vaccine storage. There was a reduction in repo
rted opportunistic vaccination, and no change in reported procedures r
egarding pertussis vaccination. Conclusions: Many factors may have con
tributed to these changes in GP vaccination procedures. While the chan
ges mostly show an improvement in adherence to NHMRC guidelines, furth
er progress needs to be made, particularly in the areas of opportunist
ic vaccination, pertussis vaccination and vaccine storage. The best me
thod of informing GPs of current vaccination recommendations needs to
be explored.
