Understanding a health problem and even having the technological capab
ility to solve it are often not enough to lead to changes in health po
licy. To help accomplish such policy changes, we propose a five-step a
pproach that involves (1) specifying the disciplines; (2) developing m
ultidisciplinary hypotheses; (3) investigating the hypotheses; (4) dev
eloping a policy 'story'; and (5) advocating these solutions to policy
makers. We use the example of neonatal hypothermia in Eastern China t
o illustrate this approach. We found that the approach both better inf
ormed policy and better motivated policy change. Using the approach ex
tended our involvement from the hospital to a wider population; in add
ition our initial solutions expanded from clinical interventions to br
oader public health approaches that proved to be quite different from
our original recommendations.
