Message from Dr Rosmarin Zacher, anaesthetic lead for preadmission clinic (PAC) and high-risk perioperative care at Coffs Harbour Health Campus:
Preadmission anaesthetic clinic (PAC) and high-risk perioperative medicine update
Dear colleagues; it is a pleasure to introduce myself as the new anaesthetic lead for preadmission clinic (PAC) and high-risk perioperative care at Coffs Harbour Health Campus. In the coming months, you can expect there to be some small changes to PAC in general, and in particular how high-risk patients are managed perioperatively.
In response to our perioperative services review, and a recent district-wide analysis of hospital-associated complications (HACs), there is ongoing the need for a more comprehensive approach to perioperative care, especially in our patients who are at higher risk for complications. I am grateful for executive support to work in this space with the aim of improving outcomes for our shared patients.
Partnering with our local general practitioners is an important part of this enhanced perioperative care, and it is hoped that ongoing collaboration will allow us to provide the best care possible for our patients and community.
 Information required to expedite the triaging process for your patients
To ensure the effective and efficient triaging process, PAC will be transitioning to an enhanced triaging model. This additional level of triaging may require more information than we currently obtain from the Request for Admission (RFA). As such we kindly request that referrals for surgery at CHHC include:
Essential: Consider providing a copy for the patient to include with their RFA that they submit their form to the hospital to book surgery (or faxing directly to Pre-Admission Clinic)
- Copy of your GP Summary (for Patients who have comorbidities, including for BMI >35 and potential untreated OSA). This is used to screen the RFA on arrival at CHHC and determine the likely need for PAC, and whether patients can be offered an OT date prior to anaesthetic review.
Desirable (where available):
- Any additional investigations including imaging reports, and
- Specialist correspondence (such as cardiology, respiratory, endocrine, renal, or other).
In addition, we ask that, especially for patients being referred for urgent surgery, that you check if they are due or overdue for specialist reviews and prompt the patient to attend as soon as possible.
Please ensure, for new referrals that results/correspondence are copied to the CHHC Pre-admission clinic: Pre-Admission Clinic CHHC (Fax: 02 6656 7491; email MNCLHD-CHHC-PAC-Clinic@health.nsw.gov.au).
High risk patients and shared decision-making pathways
We are aiming to streamline the flow of patients through their pre-operative assessment, optimisation and preparation for surgery. Your assistance in this process is critical in helping us all to improve efficiency and reduce unnecessary delays to surgery.
Elderly patients often have elements of frailty or cognitive dysfunction, and are at increased risk for perioperative complications. As such, please consider referral for a comprehensive geriatric assessment pre-operatively. Your expertise in helping patients to navigate Advance Care Planning is also invaluable in this setting.
Changes to perioperative GLP1-agonists, anticoagulants and antiplatelets – Implementation 4 August 2025 – in line with two new clinical practice guidelines
- Clinical Practice Recommendations regarding patients taking GLP-1 receptor agonists and dual GLP-1/GIP receptor co-agonists prior to anaesthesia or sedation for surgical and endoscopic procedures. A consensus clinical practice recommendation endorsed by the Australian Diabetes Society (ADS), National Association of Clinical Obesity Services (NACOS), Gastroenterological Society of Australia (GESA), and Australian and New Zealand College of Anaesthetists (ANZCA). Published April 2025
- Patients will continue taking their GLP1-a regardless of the indication (ie. For weight loss or diabetes)
- These patients must undertake an extended 24-hour modified (clear) fluid diet to mitigate the risk of aspiration of gastric contents with anaesthesia and sedation (including for endoscopy)
- Guidelines on Periprocedural Management of Anticoagulant and Antiplatelet Agents. ​ Sydney: Clinical Excellence Commission NSW. Published March 2025.
- There are minor changes especially in relation to last dose preoperatively for DOACs, and when to restart based on bleeding risk of the procedure
Changes to bowel prep in Coffs Harbour – implementation September 2025
PlenVu bowel preparation has now been approved for use at CHHC. The main change is that dose timing depends on whether a patient is booked on a morning or afternoon list. It is hoped that our renal and heart failure patients will have less fluid shifts in association with this bowel prep.
I look forward to sharing more about perioperative processes as they develop, and welcome stakeholder engagement by inviting all craft groups to collaborate in this space. Please do not hesitate to reach out should you wish to be involved more closely. I would also be very happy to present on perioperative-related topics at craft group meetings, upon invitation.
Many thanks in advance for your assistance in providing high value care to our patients and community.
