Better Drug ComplianceBetter Drug Compliance
• If patient believes treatment is important and beneficial, it often is more effective.

Outcomes of PharmacotherapyOutcomes of Pharmacotherapy
• Influenced by:– Past experiences with medications– Acceptability of taking medication in
social environment– Certain drugs carry social stigma– Patient's attitude toward personal health– Patient's expectations of
pharmacotherapy
Pharmacology for Nursing: A Pathophysiology Approach, Fourth EditionMichael Patrick Adams | Leland N. Holland | Carol Urban
Ethnicity and CutlureEthnicity and Cutlure
• Ethnicity– Biologic and genetic similarities
• Culture– Set of beliefs, values, and norms that
provide meaning for an individual or group
• Both have influence on medication outcomes.
Pharmacology for Nursing: A Pathophysiology Approach, Fourth EditionMichael Patrick Adams | Leland N. Holland | Carol Urban
Cultural CompetenceCultural Competence
• Ability to provide care to people with diverse values, beliefs, and behaviors, including ability to adapt delivery of care to meet needs of these patients– Dietary considerations– Alternative therapies– Beliefs about health and disease
Pharmacology for Nursing: A Pathophysiology Approach, Fourth EditionMichael Patrick Adams | Leland N. Holland | Carol Urban
Variables of Culture and Ethnicity That Variables of Culture and Ethnicity That Impact PharmacotherapyImpact Pharmacotherapy
• Diet• Alternative therapies• Beliefs of health and illness• Genetic differences

Figure 9.1 Holistic model of pharmacotherapy: For pharmacotherapy to be successful, the nurse must consider psychosocial, cultural, environmental and biologic variables that could affect drug response.

Obstacles to Access to Health Care Obstacles to Access to Health Care
• Inadequate health insurance• Cost of treatment and drugs• Limited medical care in rural areas

Influence of Illiteracy on Health Influence of Illiteracy on Health CareCare
• 48% of English-speaking population is functionally illiterate
• Prevents patient from being able to read drug labels
• Prevents understanding of written treatment instructions
• Prevents reading of brochures regarding medication or disease

Influence of Illiteracy on Health Influence of Illiteracy on Health CareCare
• Prevents understanding of importance of pharmacotherapy

Genetic PolymorphismsGenetic Polymorphisms
• Two or more versions of the same enzyme
• Caused by single-base mutation in DNA• Amino acid change in enzyme• Enzyme function changes• Pharmacogenetics—study of genetic
variations that cause differences in the way patients handle medications
