Polypharmacy 1 Flashcards
Sources of information for drug history of a patient in rehab community hospital
- Letter from GP
- SystemOne - see GP records and what medications their on
- Summary care record on the spine - check repeat meds, allergy information
- Northamptonshire care record - similar to summary care record
- D/C letter from hospital
- Copy of drug chart
- Repeat prescription slip
- Actual medication from home
- Ask patient/carer
What do make sure you document?
- Indication for anticoagulant drugs
- Reason for stopping medications
- Reaction to allergies
- Document if on warfarin - on seperate chart
Writing doses on prescription
- Can use g or mg
- But must write microgram, nanogram, units
Prescribing times per day
- If prescribe QDS ensure circle 4 times in the aministration time column
How to cancel prescription
Cross through on L side
Cross through on R hand side where nurses sign
What can you do with dose in PRN?
Can do dose range eg 15-30mg
What does community hospital have?
- List of medications that can be signed by doctor if patient needs them
- Basic things like paracetamol, lactulose, gaviscon
Prescribing insulin
- Prescribe by brand name and type (eg humulin M3)
- Prescribe concentration too eg 100 units/ml
- Can prescribe rapid acting novorapid PRN if at risk of hyperglycaemia
What to think re creatinine clearance?
Decreases 8mls/decade after age 30
Measuring renal function in patients
- U&E - gives eGFR - rough estimate based on age, gender and creatinine level - doesn’t take into account size of patient
- Cockcroft-Gault equation - calculates creatinine clearance (estimates eGFR) (use for age 75 and over if dosing for DOACs, nephrotoxic, meds cleared renally with narrow TI)
Key meds to be aware of risk in older patients
- NSAIDs - sodium, renal impairement, GI bleeding (need PPI at least), use topical ibuprofen/diclofenac instead
- Hypoglycaemics - gliclazide
- Antidepressants - hyponatraemia, postural hypotension (withdraw gradually). Max daily dose citalopram for over 65s is less
- Z drugs and benzodiazepines - falls, confusion, cognitive impairement
- Anticoagulants - indication, are they on correct dose for indication? weight? renal function? age?
- Opioids - good for acute/palliative care pain, not good for long term pain - confusion, constipation
Problem with polypharmacy
- 10 or more medicines =. 300% more likely to be admitted to hospital
- Can cause admissions to hospital - adverse reactions
What to first check if new symptoms of person?
Could it be side effect of new medication prescribed - CHECK THIS FIRST before prescribing anything
