Top 30: Why you should listen to TayTay without taking drugs

Taylor_Swift_112_(18119055110)

 

Presenting for prescription is the 2nd most common reason for encounter in General Practice.

As a new GP Registrar you will inevitably be tested out by the local drug seeking community to see if they can get their medications from you. Whilst you can approach this empathetically, your eventual ‘no’ may still feel ‘Mean,’ but as Taylor Swift will say- ‘Shake it off’- check out this video parody to remind you why:

I wanted to start this post by highlighting the best prescribing is sometimes NO prescribing at all. This goes for drugs of dependence but also a whole range of medications.

In fact, Choosing Wisely has PPIs, antihypertensives, and statins in mind, as well as benzodiazepines.

After NO prescribing, is DE-prescribing. Yes, the most useful thing you can learn is how not to write scripts and how to stop writing scripts. Especially in the elderly, who have increased drug-related adverse events, hospitalisations and mortality with increased medication.

AFP: Thinking through the medication list. Appropriate prescribing and deprescribing in robust and frail older patients.

Deprescribing is a really important skill to learn, but remains a new concept as evidenced by the fact its the only word that spell check doesn’t recognise in this entire article.

Ok, so step number 1- consider if your patient actually needs this prescription. The World Health Organisation has developed a Guide to Good Prescribing. If you still decide yes, you want to prescribe a medication for this patient, then there are a few more things you need to know.

If you are completely new to the PBS in private practice, you must go to the Medicare site and complete their online learning modules ‘PBS for new health professionals’ and ‘Prescribing in private practice’. This will give you an overview of the things you must include on your prescriptions, which ones you need to handwrite, what authority and streamlined authority are, and PBS safety net information. regulations 22 and 24, and prescriber bag supplies.

Now its likely you will at some stage prescribe some medications in the top ten lists. Did you notice that the Choosing Wisely medications (statins, antihypertensives and PPIs) make up 50-90% of those lists? As well as Australian Prescriber, the NPS website is another good source of information. If you can get your hands on eTG (Therapeutic Guidelines), the AMH (Australian Medicines Handbook), and/or Paediatric Pharmacopoeia– they are also often useful resources.

Ok ok, I know you still have TayTay stuck in your head, and you want to know more about prescribing S8’s and other controlled medications.

Its really important to know the legislation for prescribing in YOUR State or Territory. Like Advanced Care Directives, motor vehicle insurance, worker’s compensation, drivers licence medicals, and many other important areas of your work, it is different in different parts of Australia. You think that sounds silly? So did someone else, so they wrote an article on it for the MJA this year:

Hua, Shen, Ge, State-based legal requirements for Schedule 8 prescriptions: why so complicated? Med J Aust 2015; 203 (2): 64-66.

But that’s how it is for now, so here are some other places to find some tips:

RACGP: Prescribing drugs of dependence in general practice

QLD: Drugs of DependencePills

VIC: Drugs and poisons regulation

NSW: Pharmaceutical services

TAS: Pharmaceutical services

WA: Medicines and poisons

NT: Medicine and Poisons Control

ACT: Pharmaceutical services

Prescribing an addictive medication can be necessary at times, and there are many people in the community who use them for various indications at various doses for various lengths of time quite appropriately. There is a big responsibility for you to decide whether or not it is appropriate to prescribe this medication to this person under these circumstances. The Opioid risk website has some additional tools to aid with your assessment of appropriateness.

So whilst there might initially be some ‘Bad Blood’ between you and your patient who didn’t get exactly what they wanted, its best that you don’t have to think ‘Should’ve said no.’

REMINDER: Don’t forget to comment with any other tips or resources you use- this resource is ‘Ours,’ not ‘Mine.’

Oxycodone 10mg; 1 tablet prn

Panadol Osteo 665mg; 2 tablets tid

Omeprazole 40mg; 1 tablet daily

Temazepam 10mg; 1-2 tablets nocte prn
