20 A systematic approach to prescribing Gathering relevant information
Medication history Prescribed medicines - Name, strength, dose, frequency. - Duration of treatment. - Medication knowledge. - Adherence - Adverse effect. For relevant medications during the past 6 months

21 A systematic approach to prescribing Gathering relevant information
Medical history OLDCARTS Onset: when did it start? (acute vs gradual) Location: where is it/ what part of the body does it affect? Duration: how long did it last? How often does it occur? Characteristics: what it is like? How bad is it? Associated signs and symptoms: Does anything else accompany the problem? (severity) Relieving or aggravating factors: Does anything make it better or worse? Treatment: what treatment have been tried already? Summarize: repeat your understanding of all the situations to ensure all necessary facts are obtained.

Characteristics: what it is like? How bad is it? Aggravating factors: Does anything make it worse? Relieving factors: Does anything make it better? Treatment: what treatment have been tried already? Severity: How the symptoms are severe?

23 A systematic approach to prescribing Prescribing
Main aims of prescribing Cure the symptoms. Cure the conditions. Aid the diagnosis.

24 A systematic approach to prescribing Prescribing
Medication selection What is the drug? (optimum dose, duration) What is the drug used for? How effective is the drug? (Evidence-based) How safe is the drug? (ADR, D-D, monitoring) Who should not receive the drug? Does the drug provide value for money?

25 A systematic approach to prescribing Prescribing
Medication review Undertaking a medication review before prescribing medicines for long term treatment. NO TEARS

26 A systematic approach to prescribing Prescribing
NO TEARS N: Need and indication If the treatment is still indicated. Whether the diagnosis is confirmed. Is the medication is inappropriately continued. Is there is a need to change the dose

27 A systematic approach to prescribing Prescribing
NO TEARS O: Open question Identify what the patient understands about his medications. Which medicine he is taking appropriately. Ask by indirect questions!

NO TEARS T: Test and monitoring The prescriber should explore whether the disease is under control and symptoms are relieved adequately. Tests that may be required to assess disease control.

29 A systematic approach to prescribing Prescribing
NO TEARS E: evidence and guidelines New guidelines and new evidence based practice.

30 A systematic approach to prescribing Prescribing
NO TEARS A: adverse effects Avoid prescribing cascade: Don’t treat an avoidable ADR.

31 A systematic approach to prescribing Prescribing
NO TEARS R: risk reduction and prevention. This is an opportunistic session for screening for alcohol, smoking, obesity, family history. Identify patients at risk to develop ADR.

32 A systematic approach to prescribing Prescribing
NO TEARS S: simplification and switching Switch to more simple regimen (sustained release).
