7 steps: Person specific issues to address

1.  Aims: What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice 

Ask person to complete PROMs (Questions to answer before medicines review) before their review

Person specific issues to address

  • Wants to be on the best medication for all her current conditions as does not want them to worsen. However, she does wonder if she needs all the medication to achieve this

 

2.  Need: Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine) 
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure) 

Person specific issues to address

  • Levothyroxine: for hypothyroidism

 

3. Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • what is medication for?
  • with temporary indications
  • with higher than usual maintenance doses
  • with limited benefit/evidence for use
  • with limited benefit in the person under review (see Drug efficacy & applicability (NNT) table)

Person specific issues to address

  • Gabapentin in pain management check indication - neuropathic pain or mechanical back pain. Query co-codamol or paracetamol and need for NSAID
  • Citalopram: check ongoing indication
  • Omeprazole: high dose, check indication, e.g. active peptic ulcer, oesophagitis, GI protection (clopidogrel, aspirin, diclofenac, citalopram)

 

4.  Effectiveness: Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?

Person specific issues to address

  • Secondary prevention of coronary events: likely to derive macrovascular benefit from tight glycaemic control; consider statin and BP control
  • Stroke prevention in AF: CHA2DS2-VASc score 4, consider replacing aspirin with anticoagulant; check rate control
  • COPD management: check symptom control (including exacerbation rate) and inhaler technique. Review ICS (single ICS not licensed in COPD) and/or escalate bronchodilation
  • Pain management: review symptoms, pain score and expectations. If gabapentin prescribed for back pain, then consider withdrawal; review NSAID
  • Depression: review duration of treatment and ongoing need
  • Hypothyroidism: check TFT result
  • CKD: check and monitor for proteinuria
  • Diabetes: HbA1c high despite three antidiabetics; check adherence.
  • Pioglitazone use is cautioned in those with CVD, consider stopping and starting an SGLT-2i

 

5. Safety: Does the individual have or is at risk of ADR/ side effects? Does the patient know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day guidance

  • Ensure discussion and clear information on which medicines to withhold at times of dehydrating illness

Person specific issues to address

  • Ankle swelling: potential ADR of amlodipine or pioglitazone. Query if furosemide still indicated.
  • GI bleeding risk: NSAID, citalopram and aspirin (or anticoagulant if added)
  • Acute kidney injury risk:
    • NSAID with CKD (eGFR 55ml/min), consider stopping NSAID
    • co-prescribed diuretic, ACE inhibitor/ARB and NSAID (‘triple whammy’)
    • co-prescribed thiazide and loop diuretic, thiazide and ACEI not appropriate
  • Metformin: reduce to maximum daily dose of 2g
  • Increase U&E monitoring
  • Cardiac events risk: NSAID and CVD – diclofenac (ibuprofen and naproxen preferred); pioglitazone (ankle swelling and ischaemic heart disease)
  • Risk of arrhythmia: QTc prolongation: omeprazole, citalopram and gabapentin
  • Medication Sick Day Guidance given for metformin, furosemide, bendroflumethiazide, lisinopril, gliclazide, diclofenac and SGLT-2i

 

6.  Sustainability: Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution 

Person specific issues to address

  • Opportunities for cost minimisation by changing liquid levothyroxine to tablets
  • Change ICS MDI (no exacerbations recently) to long-acting bronchodilator in a lower carbon emission formulation e.g. tiotropium soft mist inhaler (Respimat®)
  • Advised to dispose of medicines through the community pharmacy 
  • Advised to only order what is needed, do not stockpile medicines  

 

7.  Person-centredness: Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask person to complete PROMs (Questions to answer after medicines review) after their review

Agreed plan

  • Stop: aspirin, diclofenac, gabapentin, Clenil® MDI, pioglitazone
  • Start: statin, DOAC for AF; tiotropium Respimat®, SGLT-2i (counsel accordingly)
  • Reduce: metformin dose to 2g daily
  • Change: co-codamol to paracetamol; levothyroxine liquid to tablets
  • COPD management: check they understand how to monitor breathlessness score, advise regarding use of new inhaler and check inhaler technique and suitability
  • Lifestyle management: smoking cessation, weight reduction, increased physical activity
  • Non-medication interventions: signpost to social support, e.g. Alzheimer’s Scotland
  • Pulmonary rehabilitation may be appropriate depending on breathlessness score
  • Ensure regular review: diabetes, COPD, CVD, BP, pain management

 

Key concepts in this case

  • Large number of medications are likely to be needed and effective, however more support may be required as adherence could be an issue
  • Identifying untreated indications (in this case atrial fibrillation)
  • Identifying high risk drug combinations particularly in those on multiple medications
  • Effect of reduced renal function on medication dose, e.g. metformin
  • Link with non-pharmacological management
  • A longer consultation may be required to ensure that there is time to cover any concerns and issues and focus on medication and deprescribe where appropriate, with appropriate follow-up
  • The need for a multidisciplinary approach
