The current “Pharmaceutical Benefits Scheme (PBS) community awareness campaign” explicitly
links the difficulties facing the PBS to patient behaviour and “waste”. The campaign suggests that
patients are taking advantage of affordable access to prescription medicines, and emphasises that
patient responsibility is “the prescription for a healthy PBS”. By neglecting to inform the public that
the pressures facing the PBS also include doctors’ prescribing habits and intensive pharmaceutical
industry marketing, the campaign has missed an opportunity to initiate a balanced and constructive
debate about the future viability of the PBS. (MJA 2003; 179: 544-545)
IT HAS BECOME SOMETHING of an axiom that increasing
cost is endangering the Pharmaceutical Benefits Scheme
(PBS), and that something must be done about it. Typically,
policy responses have been to target the prescription end-
user — the patient. Successive governments have increased
patients’ out-of-pocket charges as a means of containing
drug costs. The present federal Government, thwarted thus
far by the Senate in its attempt to increase the patient co-
payment, is trying an alternative — appealing to patients’
moral sensibilities rather than their hip-pocket nerve.
The current “PBS community awareness campaign”,
1
an
initiative of the National Strategy for Quality Use of Medi-
cines (QUM)
2
has been launched at a reputed cost of $27
million through a nationwide advertising strategy.

The
objective of informing the Australian public about the
operation, strengths and costs of the PBS is laudable.
However, the tone of the campaign is morally charged, with
the suggestion that many Australian patients are not acting
responsibly in their use of prescription medicines. The two
main mediums of the campaign — a series of television
advertisements and an information booklet — emphasise an
association between patient behaviour, “waste”, and the
increasing financial pressure on the PBS, a pressure which
imperils the future viability of the scheme. It appears that
patient responsibility is “the prescription for a healthy PBS”.
As part of the National Medicines Policy, the strategy for
QUM is underpinned by a set of principles, the first of
which is “the primacy of consumers”. The strategy claims to
recognise “the wisdom of consumers” and states “consumer
involvement in all aspects of the Strategy is critical”.

Far
from incorporating the wisdom of patients, the present
campaign appears to selectively choose more extreme exam-
ples of misuse of medicines to establish a moral position and
place the responsibility for increasing prescription demand
on patients.
The campaign booklet states “some people like to get a
prescription every time they visit a doctor”. This statement
implies that patients drive the demand for prescriptions and
that the low cost of prescription medicines promotes waste-
ful behaviour. The campaign repeatedly advises patients to
take note of the full cost of the prescription that is borne by
the Scheme (this is now highlighted on prescription labels).
With such information, patients can “use the PBS responsi-
bly” and minimise “waste”. Patients are also exhorted to
consider their need for repeat prescriptions, but are not
advised of the dangers of stopping treatment for some
serious disorders (eg, diabetes and heart failure).
The National Medicines Policy document raises the con-
cern that “easy access can work against the quality use of
medicines”, offering the common anecdote of patients’ stock-
ing up unnecessarily on prescription medicines “.. . because
they are available free or at low cost”. While patients probably
do initiate a certain amount of unnecessary prescription
demand, the relationship of this to the cost of a prescription is
not clear in the available evidence.
4
Further, there is no
substantial evidence to show that such behaviour is common
enough to be a major contributor to rising drug expenditure.
The emphasis on patient responsibility reveals a conviction
that prescription subsidy through the PBS results in signific-
ant “moral hazard”. In other words, low out-of-pocket cost
generates unnecessary prescription demand or “waste”.
Arguments for the operation of a “moral hazard” rest not
on direct observations of patient behaviour, but on studies
of aggregate prescribing data.
5
Rather than drawing on the
wisdom of patients, fluctuations in use of prescription
medicines after changes to out-of-pocket costs are used to
make inferences about patients’ motivations. Differences in
rates of use of “essential” therapies compared with “discre-
tionary” therapies are taken as proxies for “necessary” and
“unnecessary” patient behaviours.
6
However, prescribing
data cannot show whether the changes in pharmaceutical
use reflect appropriate or inappropriate patient responses to
increased cost; nor can they reveal the motives of patients
who have received prescriptions. Increased demand when
drugs are affordable does not itself mean that patients are
using medicines unnecessarily.

how helpful is blaming patients?
