Genetic Counseling Practice Flashcards
History of Genetic Counseling
speculation on inheritance -> return of Mendel -> eugenics movement -> human subject protections -> medical-preventive era -> patient’s rights movements -> shared decision-making -> human behavior research -> psychotherapeutic model
Sheldon Reed’s 3 Requirements of Genetic Counseling
- knowledge of human genetics
- teach and provide genetic information to full extent known
- respect for sensitivities, attitudes, and reactions of clients
Case Preparation
- patient demographics
- indication/reason for referral
- intake notes
- family history questionnaire
- relatives’ medical records
- patient’s medical records
- differential diagnoses
- inheritance, features, management of conditions
- testing options
- referrals
- resources
- anticipating patient questions
Contracting
- agenda, building rapport, working relationship, therapeutic alliance, goals
- process of bidirectional evaluation of knowledge, emotions, expectations, and goal-setting conducted by client and counselor to arrive at mutual understanding, respect, trust, consent, which is subject to adaptation as relationship progresses
Family History
- constructing relevant, targeted, and comprehensive personal and family histories and pedigrees
- assess individuals’ and their relatives’ probability of conditions with a genetic component or carrier status based on pedigree
Medical History
- general: overall health/chronic illnesses, medical concerns, medications, hospitalizations/surgeries
- prenatal: RPL, infertility, drug and alcohol exposures, birth defects
- pediatric: pregnancy and delivery, APGARs, neonatal course, when concerns arose and of what kind, developmental history, cognition and socialization in school
- cancer: details of diagnosis and treatment, current screening practices, environmental exposures
Patient Education
- effectively educate clients about a wide range of genetic and genomics information based on their needs, their characteristics, and circumstances of encounter
- write concise and understandable clinical and scientific information for audiences of varying educational backgrounds
- several influences may affect patient comprehension and engagement
Risk Assessment
- centers on genetic condition, differentials, impact of condition, symptoms, management, impact for other relatives
Influences on Perception of Risk
- internal factors: personal attributes, beliefs about illness, perception of vulnerability, level and accuracy of knowledge
- external factors: aspects of disorder, family experience, experience in genetic counseling
- numeric probability, context, perceived severity, heuristics also influence risk perception
