INTRODUCTION
Medication Adherence:
 The patient’s conformance with the provider’s
recommendation with respect to timing, dosage and
frequency of medication-taking during the prescribed
length of time.
 It is a factors that determines the therapeutic out comes,
in a patient suffering from chronic illness/diseases.
Compliance:
How well the patient follows the instruction of when and
how to take the medication
Persistence:
Duration of time patient takes medication, from initiation
to discontinuation of therapy 2
CAUSES OF MEDICATION NON-ADHERENCE
 Socio-economic
 Poor socioeconomic status, illiteracy, unemployment
 Lack of family or social support
 lack of financial resources
 Busy work schedules
 High cost of medication
 Health care system related
 Relationship of doctor-patient
 Poor or lack of proper communication regarding the
beneficial effect of taking medication, instructions for
use and side effects
 Poor medication distribution
3
 Therapy related
 Complexity of medical regimens,
duration of treatments
 Lack of immediate benefit of therapy and treatment
interferes with lifestyle
 Condition related
 Severity of symptoms (chronic illness requires long
term drugs administration OR few or no symptoms)
 Patient related
 Impairments such as visual, hearing and cognitive
impairments and swallowing problems
 Lack of motivation, apprehension about possible
adverse side effects
 Stress, anxiety 4
PHARMACISTS ROLE IN MEDICATION ADHERENCE
 Pharmacists can improve medication
adherence because they can actually show
the medication to the patient and relate any information
to the medication itself.
 Educate patients regarding medication adherence
 Pharmacists can impart the information that patients
need to know such as-
 Name and purpose of the drug,
 When and how to take the medication,
 Possible side effects, Precautions, Interaction with
food or other drugs,
 Duration of therapy,
 Action to take if a dose is missed etc.

 A pharmacist can advice to prescribers on the
simplification of drug regimens and reinforcing factors
which may contribute towards medication non-
adherence.
 A pharmacists can assess the
patient’s knowledge of their
drug therapy and usual medication
habits
 The pharmacists can also assess the patient’s ability to
comprehend and recall information, and if an adverse
drug reaction may discourage medication adherence. 6
Strategies to improve the pharmacist-patient
relationship:
 Be friendly and approachable to the patient.
 Improve communication skills.
 Take into account the spiritual and psychological needs
of the patient.
 Improving patient education.
 Give clear explanation.
 Check the patient understanding.
 Simplify the therapeutic regimes.
 Monitor the side effects.
 Monitor the beneficial effects.
 Speak the same language of patient.
 Involvement of patient treatment discussion.

MONITORING OF MEDICATION ADHERENCE
 Assessment, quantification,
measurement and evaluation
of adherence
 Direct and Indirect methods
 The direct measurement includes –
 drug monitoring
 detection of the drug or its metabolites in biological
fluid
 direct observation therapy
 Most accurate methods of adherence measurement
but are expensive 8
 The Indirect measurement includes –
 self reports,
 pill counts,
 rates of prescription refills,
 assessment of the patient’s clinical response
 measurement of physiologic markers as well as
patient diaries
9
Direct Measurement:-
 Home finger prick sampling
 Biological markers
 Directly observed therapy
Indirect Measurements:-
 Self-report measures (using questionnaires)
 Morisky’s medication adherence scale
 Medical outcome adherence study scale
 Brief Adherence Rating Scale
 Electronic Adherence monitoring
