GERIATRIC EMERGENCIES • Introduction: Why? • Pathophysiology • Principles of Geriatric Emergency Medicine • Geriatric Competencies for EM Residents • Specific Important Acute Geriatric Illness • Conclusions and Summary Emergency Medicine Clinics of North America, May 2006.
INTRODUCTION: WHY? • The Graying of America • The Elderly Are Special • Need for Education
The Graying of America • The elderly (>65) are 12% of the population • By 2050 they will be 21% • The very elderly (>85) are the fastest-growing age group • They use 50% of the federal health care budget • They spend the most on drugs
ED RESOURCE USEBY THE ELDERLY (1 of 2) • More than 15% of all ED patients • 40% of all EMS arrivals • More emergent and urgent • More comorbidities • More complicated work-ups • More labs and x-rays
ED RESOURCE USEBY THE ELDERLY (2 of 2) • Greater rate of admissions • 50% of ICU admissions • Stay longer in the ED • Higher rate of mortality and morbidity • More misdiagnoses • More ED bouncebacks
THE ELDERLY ARE SPECIAL They are not just old adults! • Own physiology • Own presentations • Own diseases: AAA, temporal arteritis, mesenteric ischemia, dementia, etc. • Own special management
Need for Education • Lack of educational materials • 69% of emergency physicians — insufficient CME • 53% — lack of training in residency • 40% of residency directors — training inadequate Ann Emerg Med. 1992;21:796-801. Ann Emerg Med. 1992;21:825-829.
SAEM Geriatric Emergency Medicine Task Force • Director of GEM Subdivision —Dr. Gernsheimer • Chairman of GEM Task Force —Dr. Rinnert • Director of GEM Research —Dr. Baron • Director of GEM Grants —Dr. Stetz • Director of GEM Simulations —Dr. Gillett • Liaison for GEM Resident Education —Dr. Doty • Director of GEM Disaster Planning —Dr. Arquilla SAEM = Society for Academic Emergency Medicine
PATHOPHYSIOLOGY (1 of 3) • Decline in physiologic systems • Loss of reserves • Decreased ability to exert homeostatic control • Accumulation of life’s stresses • Diseases • Environmental hazards — toxins • Drugs
PATHOPHYSIOLOGY (2 of 3) • Renal • Hepatic • Immunologic • Pulmonary • Cardiovascular • CNS and sensory • Musculoskeletal • Body habitus
PATHOPHYSIOLOGY (3 of 3) • More diseases • More complicated • Less ability to cope • Greater severity • More adverse drug reactions (ADRs)
Dr. Gernsheimer’sABC’sfor the Elderly A —Attentive & Aggressive B —Be Nice & Be Patient C —Careful & Compassionate S —Suspicious & Supportive
BE NICE! “When I was young I appreciated cleverness but when I became old I appreciated kindness much more” —Margaret Mead
Principles of Geriatric Emergency Medicine (1 of 2) • The patient’s presentation is complex • Diseases present atypically, making diagnosis more difficult • Comorbidities and impairments have confounding effects • Polypharmacy is common and often causes problems • The risk of ADRs is increased
Principles of Geriatric Emergency Medicine (2of 2) • The elderly may decompensate rapidly • It is important to recognize cognitive impairment • Expect decreased functional reserve • Functional status is important • Social issues are extremely important • The ED visit is an opportunity!
Geriatric Competenciesfor EM Residents • Atypical presentation of disease • Trauma, including falls • Medication management • Effect of comorbid conditions • Cognitive and behavioral disorders • Palliative care and end-of-life issues • Emergent intervention modifications • Transitions of care
Acute myocardial infarction Pulmonary embolism Pneumonia Acute abdomen Hyperthyroidism Hypothyroidism Alcoholism Depression Drug therapy Sepsis Physical abuse CLINICAL SITUATIONS WITH ATYPICAL PRESENTATIONSIN THE ELDERLY
Altered Mental Status • AMS may be subtle and missed • Differential diagnosis of AMS is broad • Dementia may mask acute AMS • Delirium: acute and fluctuating mental status • Cause of delirium can be life-threatening • Causes: Sepsis, ADR, cardiovascular, neurologic
Neurologic: CVA, SDH Infections: UTI, pneumonia Cardiovascular: atrial fibrillation, CHF, MI ADR Metabolic: dehydration, elect., HHNK Abdominal events: perforation, bleeding Psychiatric: depression, abuse ETIOLOGIES:RAPID FUNCTIONAL DECLINE
Medications in Elderly PEOPLE • Average 4.5 prescription drugs, 2.1 over-the-counter drugs • Adverse reactions twice as likely • Half of hospital admissions for ADRs involve elderly people
Altered Pharmacokinetics & Pharmacodynamics • Decreased functional reserve • Changes in volume of distribution • Drug clearance impaired • Paradoxical reactions occur
Drugs to Consider Avoidingin Elderly Persons • Drugs with: • Long half-life • Prominent anticholinergic side effects • Low therapeutic-to-toxicity ratio • Muscle relaxants • Certain NSAIDs
Digitalis Sedatives Antidepressants Steroids Alcohol Barbiturates Anticonvulsants Neuroleptics Antihistamines Diuretics Antihypertensives DRUGS IMPLICATED IN DELIRIUM
Atypical Presentationsof Infections • Vague symptoms, altered mental status, functional decline • Serious infection without fever • Pneumonia without cough • UTI without flank pain or dysuria • Intra-abdominal infection “without pain” • Invasive cellulitis without pain
Infections in ElderlyNursing Home Patients • Pneumonia • UTI • Skin infection • Intra-abdominal infection • Meningitis • Endocarditis
Increased Mortality fromInfections in Elderly Patients Pneumonia 300% Upper UTI 750% Sepsis 300% Appendicitis 1750% Cholecystitis 500% Tuberculosis 1000% Endocarditis 250% Meningitis 300%
Abdominal Pain (1 of 2) Very dangerous but easy to miss! • >50% require admission • 33%42% require surgery • Mortality 9 that of younger patients • Overall mortality 10%14%
Abdominal Pain (2 of 2) • Diagnosis of abdominal pain in the elderly is difficult • High rate of admission and surgery • Red flags: upper abdominal pain (MI?), ill appearance, and abnormal vital signs • Syncope or hypotension — think AAA • Severe pain — think mesenteric ischemia • Symptoms and signs are subtle! • Be very careful — “over-test”
ACUTE CORONARY SYNDROME • AMI is the leading cause of death in the elderly • The elderly commonly present without classic pain • AMI should be suspected with atypical pain, CHF, syncope, SOB, acute confusion, or functional decline • History alone is sufficient to admit a patient • Normal ECG and labs do not rule out ACS in the ED • The elderly may tolerate medications poorly • Decisions should be based on patient’s physiologic age, functional status, and wishes, not on age in years
Summary To optimize care, need a comprehensive model that considers: • Complexity of chief complaint • Atypical disease presentation • Comorbidities • Polypharmacy ― ADRs • Cognitive impairment • Decreased functional reserve • Assessment of functional status • Need for social and psychological support
