Polypharmacy Flashcards
How and why does Polypharmacy occur?
It is often due to the patient experiencing more than one health condition, we call these people complex patients. such as Diabetes, stroke and Depression
What is multi-morbidity?
the co-occurrence of two or more chronic medical conditions in one person.
What is Polypharmacy?
The use of many medicines together (often more than four or five medicines), or a medicine not matching a diagnosis.
What is hyperpolypharmacy?
Use of ten or more regular medicines by an individual. This is also sometimes Called major polypharmacy or excessive polypharmacy.
Define Appropriate polypharmacy
Multiple medicines, all of which are clinically indicated and accepted by the individual as improving their wellbeing and achieving the health outcomes that are important to them.
Some medical conditions are best treated with multiple medicines, for example, congestive heart failure, HIV infection or diabetes.
What is Oligopharmacy?
The deliberate avoidance of polypharmacy, ie, using fewer than five regular medicines and minimising the number of doses an individual has to take in their day.
This approach is growing in popularity in end-of-life care but may also be useful for individuals who place a high value on taking fewer medicine
Define Problematic PolyPharmacy
Also referred to as inappropriate polypharmacy. More medicines than an individual needs to achieve the health outcomes that are achievable and important to them, medicines that are having a negative impact on the individual’s wellbeing, medicines that are not adding any value, medicines that result in drug-drug or drug-food interactions or any other negative impact on the individual’s lifestyle that could be avoided
Problematic medicines can be changed to an appropriate alternative or solved by….
Deprescribing
Define Deprescribing
The process of stopping or reducing medicines with the aim of eliminating problematic polypharmacy, and then monitoring the individual for unintended adverse effects or worsening of disease.
It is essential to involve the individual (and their carer) closely in deprescribing decisions in order to build and maintain their confidence in the process.
Define Pseudopolypharmacy
The healthcare record suggests polypharmacy but the individual does not take all the medicines on their prescription/medicines list.
This can occur when medicines are stopped by the individual or a prescriber but, for a number of reasons, not removed from the repeat prescription.
Ms F (89 years old) has terminal pancreatic cancer and is under an end of life pathway. Her regular medication regime has been adapted to feature less than five medications. What type of polypharmacy is this?
Oligopharmacy
Mr S (47 years old) suffers from diabetes and is prescribed metformin 500mg TDS with food, gliclazide 80mg BD with food, ramipril 5mg OD, bendroflumethiazide 2.5mg OM and simvastatin 40mh ON. What type of pharmacy is this?
Polypharmacy
Mrs Q (62 years old) suffers from diabetes, heart failure and atrial fibrillation. She is prescribed a total of 12 different medicines to be taken through-out the day. What type of Pharmacy is this?
Hyperpolypharmacy
How transfer of care could lead to polypharmacy?
Moving between care settings has been shown to result in polypharmacy, for example, a patient may transfer between hospital, general practice and a care home, with new medicines being added at each stage3. There is evidence that patients are discharged from hospital with an average of one-and-a-half more medicines than they were admitted with4. When patients transfer between different care providers there is a greater risk of poor communication and unintended changes to medicines.
When patients move from one care setting to another, between 30 and 70 percent have an error or unintentional change to their medicines
What is reflex prescribing?
The prescribing cascade occurs when an adverse drug reaction is misinterpreted as a new medical condition. New medicines are started in order to manage the unrecognised side-effects of an existing medicine2.
Alternatively, a patient may end up in a situation where a prescribing vortex has occurred, in which each medicine causes a side-effect that is treated by the next.
