Definitions – “CCP model”
• Medical discipline which provides community based, continuing, comprehensive, preventative primary care
![Page 3: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/3.jpg)
Definitions - RACGP
General Practice is the provision of primary continuing comprehensive whole-patient care to individuals, families and their communities
![Page 4: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/4.jpg)
Scope of Family Medicine
• Interface between medicine and the community – good communication is vital
• Defined by the doctor – patient relationship rather than by a disease process. The commitment to the patient as a person is prior to any particular health problem
• must take responsible action on any problem the patient presents – scope is unlimited
• Point of first contact, enable access to health care
![Page 5: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/5.jpg)
Scope
• Management of many common conditions• Preventative care and health promotion• Early diagnosis• Acute illness and medical emergencies• Psychological care• Chronic disease management• Palliative care
![Page 6: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/6.jpg)
Scope
• Health Care Coordination – make appropriate referral to other doctors as well as health and community services. Assist patient in accessing health care
![Page 7: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/7.jpg)
Nature of Family Medicine
• Patients presenting in community settings have very different problems to patients referred to hospitals
• FP’s see well patients for health promotion and preventative management
• When patients are not well they often present with vague, undifferentiated symptoms
• Multiple pathologies
![Page 8: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/8.jpg)
Nature of Family Medicine
• Role of Family Physician to identify serious and life threatening diseases early
• Also to allay anxiety and health fears when there is no serious pathology
• 25-50% of presentations have no disease specific diagnosis even after thorough investigation
• Family Physicians need to be able to work with uncertainty and diagnostic dilemma
![Page 9: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/9.jpg)
Illness and Disease
• Illness is a personal experience of physical or psychological disturbance encompassing sensations, feelings, disabilities and effects on activities and relationships
• Disease is the biological process physicians use to categorise and define illness.
![Page 10: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/10.jpg)
Different Agenda
• Patients present with problems or illnesses• Patients are looking for advice, reassurance,
solutions• Doctors are interested in diseases,
classifications, diagnoses and treatments• The role of the Family Physician is to respond
to illness and recognise disease
![Page 11: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/11.jpg)
Doctor Centered Approach
• Where management occurs according to traditional medical models of disease
• Often seen in Tertiary hospitals where patients usually have a clearly defined disease and where full range of diagnostic and treatment options are located
![Page 12: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/12.jpg)
Patient Centered Approach
• Understanding the patient first• Understanding the patient’s disease• Negotiating a management plan with the
patient
![Page 13: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/13.jpg)

Undifferentiated Illness
• Tiredness / fatigue• Sleeping problems• Anxiety and stress• Dizziness• Headache• Anorexia / nausea• Weight loss or gain• Pain – abdominal, chest, musculoskeletal• Sexual dysfunction
![Page 15: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/15.jpg)
Diagnostic Strategy
Family Physicians need to develop a strategy to deal with undifferentiated illness
• Address patient’s agenda • Early Recognition of disease state• Avoid mistakes and litigation• Reduce doctor stress
![Page 16: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/16.jpg)
Patients Agenda
Important to explore what outcome the patient desires from bringing their complaint to the doctor. May be different to Doctors agenda of diagnosis and cure
• Someone to talk to• Fears and anxieties about meaning of symptoms• Concern about a particular disease• Conflict in interpersonal relationships (advocacy)
![Page 17: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/17.jpg)
Diagnostic Model (Murtagh)
• Probability diagnosis• Serious Disorders not to miss• What is often missed – pitfalls• Masquerades• Hidden Agendas
![Page 18: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/18.jpg)
Probability Diagnosis
• The most likely diagnosis, not necessarily disease state
• Based on epidemiological knowledge acquired within a particular community about common illnesses
• Requires experience in community medicine
![Page 19: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/19.jpg)
Serious Disorders
particularly those where the prognosis is changed by early diagnosis
• Neoplasia, esp malignancies• Infections (HIV/AIDS, bacterial sepsis, infective
endocarditis, tuberculosis, malaria, dengue)• Coronary Disease• Imminent or potential suicide• Intracranial lesions – SAH, SDH• Ectopic pregnancy and endometritis
![Page 20: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/20.jpg)
Pitfalls
Non life-threatening problems that are easily overlooked, learnt by experience
• UTI• Allergy• Drugs and alcohol• Menopausal symptoms• Early pregnancy• Faecal impaction• Depression, esp with somatisation
![Page 21: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/21.jpg)
Masquerades
Conditions which cause a non-specific “shopping list” of symptoms, sometimes with a normal physical examination
• Anaemia• UTI• Depression• Diabetes• Hypothyroidism• Chronic Renal Failure• Infections eg CMV, hepatitis, EBV• Neurological d/o – Parkinson’s, Guilliain- Barre, MS• Connective Tissue Disorders - SLE
![Page 22: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/22.jpg)
Masquerades
• Ward Tests-Urinalysis, pregnancy test, blood sugar,
Hb• Consider pathology screen
-Full blood count, iron, electrolytes, urea, creatinine, TSH, relevant antibodies
![Page 23: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/23.jpg)
Hidden Agendas
• “ticket of entry” where a symptom justifies attendance
• Patient may or may not have insight into this• Plea for help• Doctors need to provide an opportunity for
patients to communicate freely – listening, being non -judgmental, empathising
![Page 24: Introduction to Family Medicine](https://reader033.fdocuments.in/reader033/viewer/2022061200/5477d3f35906b55f318b468e/html5/thumbnails/24.jpg)
