What are we going to do?

• A quick run through core principles and challenges in Polypharmacy Management

• Example from the receiving unit

Disclaimers

• Stopping drugs is not the primary goal

• Thinking openly and carefully is the goal

Three overlapping areas

So how old is your patient?

• Lots of old folk who are physiologically younger than years

– Most of whom will be rich

• Lots of younger folk who are physiologically older than years

– Many of whom be deprived

prophylaxis

Emergency admission

• Crushing central chest pain at home

• Sweaty and clammy

• Resolved after morphine

• Now up and about on the ward. Confused looking for husband

Tests

• Troponin >> lots

• ECG > Deep inverted anterior T waves/ AF (old)

• Chest X ray > mild congestion (but poor film)

• BP 98/40

• Urea 10 Creat 132

– Baseline Urea 8 / Creat 124

• WBC 8.6 Hb 98 MCV 92 Plat 140

Diagnosis

• Acute Coronary Syndrome

• Delirium

Management

• Cardiology

– Medical Management would not angio

– ECHO if tolerated

• Nursing

– Up and about a lot increasingly distressed

So what is ‘medical management’ here ?

• Fondaparinux /Clopidogrel /Aspirin /Apixiban

– NO!

• Aspirin and Clopidogrel and Fondaparinux

• Clopidogrel and Apixiban

• Aspirin and Apixiban

• Aspirin and Clopidogrel

• Clopidogrel

• Aspirin

• ????

How do guidelines help us manage these groups?

Honesty about Guidelines

• Done with a SINGLE disease in mind

• Based on studies in non- frail

• Are not made with the frail or multimorbid in mind

• They are GUIDElines but– Can be VERY hard to ‘defy’ them

• Almost no trial evidence in frail adults

– Different pharmacology

– Huge comorbidity

• Use the best we have ie younger adults

– Different Absolute Risk

– Different Harm rates.

• Almost no trial evidence in frail adults

– Different pharmacology

– Huge comorbidity

• Use the best we have ie younger adults

– Different Absolute Risk

– Different Harm rates.

Why did you jump off a cliff?

Because the Guideline told me to.

Game changing concepts

If guideline says Prescribe X drug it is GUIDANCE not INSTRUCTION and not prescribing may well be acceptable (and often desirable) in a range of situations

One size does not fit all.....

Medication in the Frailest Adults

• Blood pressure - avoid blood pressure < 130 systolic and or < 65 diastolic [except in LVSD]

• Blood sugar control - avoid lowering HbA1c < 65

• Treatments to maintain renal function and avoid progression of proteinuria - avoid treating unless considered to have sufficient life expectancy to see benefit

• Use of blood thinners - avoid the use of combination blood thinners

• Heart rate control - reduce or stop heart rate limiting medication if pulse < 60

This lady

• Aspirin or Clopidogrel alone

• A lot less of her other medication….

Facts and figures• BP 106/56

• HbA1c 40 mmmol/mol 5.8%

• Urine Albumin/Creat ratio – trace microalbuminuria

• Creatinine 124 eGFR 45

Three Take Home Messages

• Addressing Polypharmacy begins and ends with individualised patient defined goals

• Frailty is a more useful concept than chronological age

• Better knowledge of efficacy and risk can aid decision making
