What is Compliance?
Defined by Haynes et al. (1979) as the extent to which a patient’s behavior, concerning medications, diets, or lifestyle changes, coincides with medical advice.
Studies estimate that about half of chronic illness patients (e.g., diabetes, hypertension) are non-compliant.
Even simple behaviors, such as using an inhaler for asthma, show low compliance rates (Dekker et al., 1992).
Predicting Compliance: The Work of Ley
Ley (1981, 1989) proposed the Cognitive Hypothesis Model of Compliance:
Patient Satisfaction: Linked to the consultation process and can predict compliance.
Understanding & Recall: Patients must comprehend and remember the information provided during consultations.
Patient Satisfaction
Ley (1988) reviewed 21 studies:
41% of hospital patients were dissatisfied with treatment.
28% of general practice patients expressed dissatisfaction.
Factors influencing satisfaction:
Affective aspects: Emotional support, understanding.
Behavioral aspects: Comprehensive explanations and prescription practices.
Competence: Appropriateness of referral and diagnosis.
Patients often prefer full disclosure, even with negative findings (e.g., cancer diagnosis).
Effect of Personalized vs. Non-Personalized Information
Study by Berry et al. (2003):
Personalized information about medications led to higher satisfaction and lower perceived risks than generalized information.
Patient Understanding
Poor understanding of health conditions affects compliance:
If patients do not understand their illness or treatment, compliance is likely to decline.
Studies Indicating Poor Patient Comprehension
Boyle (1970): Examined patient definitions of illnesses:
Definitions of illnesses like arthritis and jaundice showed significant misunderstanding.
Roth (1979): Explored beliefs about peptic ulcers and lung cancer, revealing misconceptions about causes and prognosis.
Patient Recall/Memory
Ley argued various factors (anxiety, medical knowledge, etc.) influence recall but age does not seem to affect it.
Bain (1977): Found 37% of patients failed to remember the name of their prescribed drug post-consultation.
Improving Compliance
Compliance is essential for patient well-being; factors that can enhance it include:
The role of information: Giving clear and comprehensible information improves compliance.
Mullen et al. (1985): Found instructional information increased compliance in 64% of cases, while Haynes noted behavioral instructions raised compliance to 75%.
Recommendations for Improving Compliance
Oral Information
Ley (1989): Suggested factors to enhance communication:
Primacy effect: Emphasize initial information.
Simplicity: Simplify messages for clarity.
Repetition: Encourage retention through repeated messages.
Follow-up interviews post-consultation can also bolster compliance.
Written Information
Ley & Morris (1984): Use of written information enhances knowledge (90% of studies), compliance (60%), and outcomes (57%).
Pre-operative information reduces post-operative stress (Janis, 1958).
Using Information to Improve Recovery
Correct, clear communication from health professionals is crucial to managing post-operative anxiety and promoting recovery.
Types of Information Affecting Recovery
Sensory Information: Helps individuals manage feelings.
Procedural Information: Educates patients about processes.
Coping Skills Information: Teaches coping strategies.
Behavioral Instructions: Guides patients on behaviors like coughing.
Role of Knowledge in Doctor/Patient Communication
Ley’s model positions doctor-patient communication as an educational exchange, where expertise transfers from professionals to patients.
Problems with Traditional Doctor-Patient Communication
Assumptions of expert knowledge overlook patient beliefs:
Patients often have personal health beliefs impacting their responses and compliance.
The Adherence Model of Communication (Stanton, 1987)
Emphasizes patient knowledge and belief systems in enhancing adherence, highlighting factors like locus of control and perceived support.
Doctor Variability
Variability among doctors is evident in clinical practices and decision-making processes due to differing knowledge, biases, and influences.
Explaining Variability in Clinical Decisions
Problem-solving models (Newell & Simon, 1972) highlight:
The nature of the issue determines strategies employed.
Heuristics vs. algorithms impact problem-solving approaches.
Clinical Decision-Making Stages
Accessing patient information helps formulate hypotheses, test these against attributes, leading to management decisions that evolve based on reassessment (Weinman, 1987).
Factors Affecting Hypotheses Formation
Health professionals’ beliefs about health.
Predictions based on disease prevalence.
Personal knowledge of the patient.
Stereotypes influencing perception.
Health professionals' mood affecting judgments.
Patient Centeredness
Emphasizes negotiation and agreement in consultations for better health outcomes.
Agreement Impacts Outcomes
Disagreements in beliefs about health can lead to poor compliance and dissatisfaction in treatment.
Conclusion
Understanding the dynamics of doctor-patient communication, compliance, and the role of health beliefs is essential for improving health outcomes and patient satisfaction.
