Why pharmacists should manage pre-operative opioid use

Written by | 15 Sep 2024 | 'In Discussion With'

Patients are “crying out” for help with opioid dose reduction according to evidence gathered during the OpioidHALT study and the impressive results have led to funding of $1.5 million to run the definitive trial, researchers Shania Liu and Jonathan Penm say.

Some 575 patients were screened for inclusion in the OpioidHALT study and 442 were excluded because of low opioid use. “That is the reality of clinical trials for you”, says Dr Shania Liu. “We know that approximately a quarter of patients in [this] population don’t use opioids on a regular basis”, she adds. Nevertheless, dosage tapering is still important for the many patients who are using opioids regularly.

OpioidHALT II

As a result of the impressive results from the OpioidHALT study Dr Jonathan Penm has now received funding of $1.5 million to run the definitive trial (OpioidHALT II). Recruitment started two months ago.  “What’s great about it is all of the pilot sites were so impressed by the pilot that they’ve all stayed on for this definitive trial. Other sites have also expressed interest because they’ve been so excited about it”, says Dr Penm. “We’re going to have more pharmacists, a lot more patients – and [it] will be primarily powered to look at those pain and quality of life outcomes”, he explains.

Pharmacists often improve medication regimens but rarely find out how much of an impact the changes have on patients’ lives. One of the useful and important findings in the OpioidHALT study was that the early benefits of reduced opioid use were sustained for three months. “It just shows you the value that pharmacists can provide to their patients – that when we improve their medicines we could be improving it for much, much longer than you realise and having much, much stronger impact”, says Dr Penm.

All the opioid-tapering consultations were recorded and patients’ reactions made a profound impact on Dr Penm.

“Many of them were just so grateful to have someone listen to them,  to validate what they’ve been going through with their pain and to support them through the opioids. In fact, most of them said, “I’ve never had any benefit from these but I just don’t know how to get off them – and I really would love some help”,  so I think we’ve got patients who are crying [out] to have pharmacists to be more involved in their care, to be more present, to listen to them, to validate what they’re going through – and that’s something that a lot of pharmacists can do”, he says.

In summary Dr Penm says:

“Any work of this calibre is extremely difficult to do with one person and we have a very large team. One of the unique aspects is how multidisciplinary it was – we have pharmacists, we have nurses, we have GPs, we have anaesthetists, we have physiotherapists, we have orthopaedic surgeons – and we know how rare it is to get all these people together in one spot and for all of them to say, “This is a really good intervention, we should be doing this, pharmacists should be leading it”. It’s just beautiful to hear. You don’t always hear that the pharmacist is the most obvious choice but in this case they are. They’re happy, they’re competent, they’re capable – and everyone else doesn’t want to do this because it is not their area of expertise. Well, with pharmacy we’re very comfortable because we know this, we know opioids, we see tapering, we know how to taper, we know what to expect”.

About Dr Shania Liu and Dr Jonathan Penm

Dr Shania Liu  BPharm (Hons), GradCertEdStud (Higher Ed), PhD, FSHP, FHEA completed her PhD at the University of Sydney looking at a pharmacist-led opioid tapering program for patients undergoing total hip and knee arthroplasty. Currently, she is a post-doctoral research fellow working at the University of Alberta in Canada where she is leading two large randomised trials looking at pharmacist-partnered management of chronic conditions such as cardiovascular disease. She also  continues to be involved in the pharmacist-led opioid tapering work looking at the impacts of opioid tapering before hip and knee replacement surgery.

Dr Jonathan Penm BPharm (Hons), GradCertEdStud (Higher Ed), PhD, FFIP, FSHP, FPS, FHEA, FANZCAP (PainMgmt, Research) is a senior lecturer at the University of Sydney School of Pharmacy in Australia. He is involved in both teaching and research and is also affiliated with the Prince of Wales Hospital, where he is involved in research with the pain team. His area of interest is evaluating hospital pharmacy services to reduce patient harm and the need for hospital care.  He currently runs several randomised controlled trials and is the Principal Investigator for OpioidHALT II.
