The World Health Organization:The World Health Organization:
Adherence:
- the degree to which the person’s behavior corresponds with the agreed
recommendations from a healthcare provider.
Compliance:
- the degree to which a patient correctly follows medical advice.
- patient is passively following the physician’s orders, while adherence
acknowledges that the patient is part of the decisionmaking process,
making this the preferred term.
Persistence:
the duration of time over which a patient continues to fill the prescription.
Non-acceptance:
- some patients may never start treatment (a type of non-adherence)
Concordance:
- the degree of accordance of therapeutic goals of patient and therapist is
defined as ‘concordance

OMS/WHO:
• ,,poor adherence is the primary reason for suboptimal
clinical benefit in many circumstances.
• ,,medication non-adherence has been associated with
increased hospitalizations, loss of productivity,
premature deaths, and increased treatment costs”.
Non-adherence to medications is widely recognized as a major public health
concern and contributes to patient morbidity, mortality and healthcare costs

CONCLUSIONS:
• Adherence to statin therapy, (as reflected by MPR), is closely related to LDL
cholesterol goal attainment in patients with diabetes and dyslipidemia.
• The probability of goal achievement appears to increase substantially when
the MPR is 0.80.
• Pharmacy records can be used to identify patients who are poorly compliant
with statin therapy and at high risk for failure to attain LDL cholesterol
goals.

• In spite of being indicated, statins were not prescribed in 33%
patients
• Of 26% patients, nonadherent to statins,
- 67% did not use the drug due to its high cost,

Patients With and Without Acute Coronary

JAMA. 2002;288(4):462-467.
Conclusions:
Elderly patients with and without recent ACS have low rates of adherence
to statins.
This suggests that many patients initiating statin therapy may receive no
or limited benefit from statins because of premature discontinuation.

Conclusions
• Adherence to diabetes medication remains an ongoing problem.
• Of the 27 studies included in the present review, the prevalence of adherence
ranged from 38.5 to 93.1%.
• Only six out of 27 studies (22.2%) reported prevalence of adherence of ≥ 80%
among their study population.
• Depression and medication cost were found to be consistent and
potentially modifiable predictors for diabetes medication-taking behaviour.

• The pharmaceutical care program (frequent counseling
sessions - every 3 months) resulted in a significantly
lower rate of discontinuation within 6 months after
initiating therapy versus usual care.
• Median MPR was very high (>99%)!
Some studies suggest that long-term adherence of chronically prescribed CV medications such as anti-hypertensives or statins may be as low as 50%.
All we know about the value of these chronic medications in reducing untoward outcomes are usually based on rigorous RCT that involve frequent visits, free medications, and pill counts to verify adherence.
The actual benefit of CV medications when they are taken only intermittently or for a short period of time and then stopped is not known for sure, but is thought to be worse based on observational studies in routine practice.
As would be hypothesized, not taking one’s chronic medications has important clinical consequences.
In this observational study in a high-risk cohort of patients with established but stable coronary artery disease, a single question was asked to examine the extent to which they were taking their medications as prescribed (adherence). Patients were followed for an average follow-up period of four years.
Those taking their medications as prescribed only 75% of the time, or less, had a more than four times the increased risk of stroke and almost a four-fold increased risk of death.
