Putting concordance for taking medicines into practice
When the medicines that doctors prescribe fail to produce the benefit they
expect, they often respond by varying the doseor selecting an
alternative medicine. Thus doctors seem to behaveas though
non-compliance is a problem for other doctors. Althoughwe know that
about half of the medicines prescribed for patientswith long term
conditions are not taken as prescribed,1 theconcerns of health professionals have focused almost exclusivelyon improving the quality of their own prescribing choices. Similarly,attention and resources devoted by pharmaceutical companies to
discovering, developing, and promoting new drugs utterly dwarftheir
efforts to see that medicines are taken by patients. Yet
non-compliance continues to represent a serious therapeutic deficit
at the core of medical practice, with consequent massive personal,
societal, and economiccost.
Patients do not comply with medication for several reasons.2
Non-compliance may be intentional or involuntary. It may relateto
the quality of information given, the impact of the regimenon daily
life, the physical or ental incapacity of patients, ortheir social
isolation. Many interventions to overcome these impedimentshave been
tried, but evidence of sustained success is scant.1
The difficulty for health professionals lies in acknowledging that it is the
patients' agendas and not their own that determinewhether patients
take medicines. Patients have their own beliefsabout their medicines
and medicines in general. They have theirown priorities and their
own rational discourse in relation tohealth and care, risk and
benefit.3 These may differ from and
sometimes contradict those of the doctors. They are, however,no less
cogent, coherent, or important.4
By drawing on these findings and insights a new relationship between
prescriber and patient was described.5 The term
concordancewas introduced. While compliance describes the degree to
whichthe patient follows the prescribed regimen of medicines,
concordancedescribes an agreement between a patient and a healthcare
professionalabout whether, when, and how medicines are to be taken.
Concordancetherefore refers to the creation of an agreement that
respectsthe beliefs and wishes of the patient, and not to compliancethefollowing ofinstructions.
Doctors and patients may not always agree. The implication of concordance is
that when this happens the patient's views takeprecedence. This
poses challenging questions about choice andresponsibility. If the
only treatment to which the patient willagree falls substantially
short of what modern medicine can achievethe doctor may be left with
a burden of responsibility that ishard to manage emotionally,
ethically, andlegally.
Practitioners are constantly urged to be both patient centred and evidence
based. Yet these two goods can conflict. The questis for the best
health outcome, but concordance implies that wemust now redefine
best outcome so as to reconcile what pharmacologycan theoretically
achieve with what the patient desires or canbear.
Non-compliance is a multifactorial problem and requires multifactorial
responses. No single blueprint for concordance exists.Nor will
concordance be achieved by acquiring new communicationskills alone.
Intentions must also change. Concordance cannotbe delivered by the
imposition of top down guidelines. Doctorsand patients must learn
how to "do concordance" not only on thebasis of established evidence
but also from their own reflectiveexperiences and from new
experimentalstudies.
Many questions need to be answered. Few of the usual sociodemographic and
biomedical variables predict non-compliance. Canwe identify some
that do? What does a concordant process looklike in practice? What
difficulties does concordance raise forpatients and how can they be
overcome? How can the ethical issuesfor doctors be addressed? What
needs to change in order to implementconcordance?
A change in the culture of the doctor-patient encounter is needed now.
Concordance presents new challenges for patients, doctors,nurses,
pharmacists, pharmaceutical companies, policy makers,and others.
Crucially, as we move forward, we must learn to createrobust
therapeutic alliances with mutual respect for both thedoctor's
professional opinion and the patient's personaldecisions.
In 2002 the Department of Health endorsed and adopted the principles of
concordance and created the Medicines PartnershipTask Force (www.medicines-partnership.org)
to carry this workforward. The task force comprises representatives
from the medical,nursing, and pharmacy professional bodies,
patients' groups, pharmaceuticalindustry, and academia. Its two year
remit is to look for waysto implement concordance in the NHS so as
to improve health outcomesand satisfaction withcare.
The BMJ will publish a theme issue on "people taking medicines" on
11 October 2003. We, the guest editors, invite contributionsfrom
researchers, patients, health professionals, policy makers,and other
stakeholders, to reach us by 15 April 2003. Submissionsshould be
made to www.submit.bmj.com, and the
editorial contactis Giselle Jones (gjones@bmj.com).
We hope to add to the storeof evidence, experience, and
controversial debate, and to learnmore about what concordance looks
and feels like in practice,how it is being taught to health
professionals and patients, howbarriers to it can be overcome, and
to what extent we can produceevidence of clinical and other benefits
for patients, practitioners,and theNHS.
