3. Patient = adherent if they take 80% of their prescribed
medicine(s).

80% compliance = General chronic disease medicines

Importance of Adherence?
50%–75% of chronically ill patients take their medication as prescribed.
Adherence comprises three aspects:
1- initiation,
2- implementation, and
3- discontinuation/persistence
Nonadherence to treatment may pose serious PROBLEMS,
1- medical,
2- social, and
3- economic .
6. Negative impact of Non- Adherence?
6
• Waste of medication
• Side – effects (Always exist- Normal flora)
• Drug Resistance-Development (1987- lipopeptides - Polymyxin-B)
• Disease progression (Negatively improved)
• Increased use of medical resources (sehat Card)
• Increase hospital visits & load
• Disease spread (Herd immunity)
• Increase disease burden
• Affect Quality of life (QoL)
• Cost effectiveness (Harm)
• Cost of treatment (?) (Fuel, Paper, Staff, Beds, Electricity)

Indicators
7. Possible Reasons of Non-adherence
• Poly pharmacy & pill burden (Regular use 5 Med)
• Inconvenient route of administration
• Frequency of taking the medication
• Side effects (ADDs- Estrogen receptors)
• Complexity of the treatment process
• Economic factors (767 % difference in Ecip-151-brands)
• Stigma & social factors
• Psychological health issues
• Cognitive impairment
• Lack of conviction (yaqeen) as to the purpose
• Less- effectiveness of treatment
• Poor relationships B/W patients & health care professionals 7

SELF REPORTs
OR
PATIENT REPORTED OUTCOMES (PROs)
“Any report of the status of a patient's health condition
coming directly from the patient, without
interpretation of the patient's response by a clinician or
anyone else”.
11. 11
PATIENT-REPORTED OUTCOMES (PROs)
SCOPE
• Adherence to treatment (GMAS-general medication adherence scale)
• Disease & its severity measurement (for example PHQ-9 for Depression)
• Quality of Life (QoL)
• Treatment Response Measurement (Quantifiable*)
• Disease Remission Measurement
12. 12
Various adherence measurement instruments
available.
Deciding which tools to use depends on,
• Healthcare setting (1,2 or Tertiary?)
• Budget
• Type of disease
• Staffing &
• Patient population.
A combination of tools will ensure the best results.
13. 13
Ideal measurement instruments.
• Easy to understand
• Short (PHQ-2)
• Native language (translation-available)
• Free
• Statistically valid
• Cover scope of disease under observation
• Likert scale
• Can Rule-out disease & measure its severity

OTHER METHODS OF CALCULATING ADHERENCE
Drug adherence rate (DAR): pills to be counted by a staff person. This creates a
proportional value between 0 and 100. The goal is over 80% for chronic disease, 90%
for tuberculosis, and 100% in antiretroviral therapy for HIV-AIDS.
Medication diaries: A written/electronic record kept with the date & time.
Pill counts: Counting doses B/W two scheduled visits. The patient provides the
medication, and they are then counted by a healthcare provider.
Prescription/Pharmacy records: Assessing adherence by tracking refills can be done
by obtaining pharmacy records. These records show the number of days between
refills and when the medication was picked up.
Direct observed Therapy (DOTs): Observer to monitor medication use. A trained
individual physically watches or dispenses the medication to the patient at each
dose. Tuberculosis/HIV.
Collecting biomarkers: Samples of urine, or blood are collected from an individual
and then tested to measure the amount of drug present in the person’s body.

25. ACTION PLAN ?
Check Which Segment of GMAS is responsible for Non-Adherence?
1) Patients personal issues?
2) Poly pharmacy or Comorbidities
3) Cost relevant issues
Address his problem.
Keep on getting GMAS, PHQ-9 and VAS questionnaire filled more frequently.
Contact physician and discuss the strategy.
26. ACTION PLAN ?
Check Which Segment of GMAS is responsible for Non-Adherence?
1) Patients personal issues?
Set An Alarm.
Use A Pillbox. (Morning evening dose labels)
