Description of intervention(s) / exposure
A prospective randomised two-arm study of opioid-naïve surgical patients consented and enrolled to the Nellie persona-based text message post-operative self-management service by the clinical pharmacy team compared to a control cohort.
This study will take place in the surgical units of an Australian Major Hospital (Frankston hospital Surgical Short Stay Unit, Acute Medical and Surgical Unit and 5GN) with real-time follow-up and monitoring at home for 30 days post-discharge via SMS .
We will compare the ‘Nellie intervention’, a persona-based, interactive and automated text messaging service with a ‘Nellie control’ arm, randomized in a 1:1 ratio.

Nellie Intervention population will be invited to accept self-management smart messaging service with timed protocol text reminders on medication management, education on pain and reminders to return unused opioid medication. Education resource links are form betterhealth available at https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/pain-and-pain-management-adults

Real time data is collected on the Nellie dashboard once patients participate in the messaging.

If a patient request further support or information they will be directed to their GP. There is no direct patient contact follow-up with phone calls beyond standard care.

Message schedule for intervention group
Day 0 Welcome message,
"Hi, I'm Nellie, your self-care service. I wish to confirm if you want to join in. Get started by replying "accept". Don't reply if you didn't ask to join in."
Evening message triggered by patient replying with 'accept"
"Hi, it's Nellie. Thanks for joining. I'm here to help you manage your own health better. At times I'll send advice for you to act on. You can opt out at any time by replying STOP."
Day 1 to 7, 14,21 and 30 "HowRu? Survey" references (1-6).
Day 1 to 4 at 10:30 and 18:00 information to limit opioid use examples include:
"Hi, Okay, keep taking your anti-inflammatory (if prescribed) along with regular paracetamol for now. Only use the Oxycodone, Tramadol or Tapentadol if required for severe pain not managed by your simple pain relief. The aim of pain relief medicine is to give you more function – you may not become 100% pain free. For more tips to help with your pain, you can text the word PAIN at any time, Nell"

"Hi again, please avoid taking your pain medication at a dose higher than prescribed, as you may get more side effects like dizziness, drowsiness or constipation. Take care, Nell."

"Remember, your body will continue to recover & the need for pain medication will gradually decrease. If you need some ideas about how to help with your pain, you can text the word Pain at any time. Take it easy, Nellie"

"Hi, it's important that you know that you don't need to complete all of the pain medication you've been given. Only take it while you need it, Nell."

"Hey, when you feel that your pain is controlled, stop your anti-inflammatory (if prescribed) & take paracetamol as required."

"Hi there, it's really important that you only use your pain medication to relieve pain. There's a high risk of them causing you harm if you take it for other reasons, Nell."

"Morning! If you're still in pain after you've finished your supplied medications, see your GP for advice. You can get some ideas about how to manage pain by replying to this message with the word PAIN, Nell."

Pain extra information message optionally triggered by the patient replying with the word "pain".
"Physical therapies can help to relieve pain. Gentle walking, stretching, strength or aerobic exercises may help to relieve pain. They can also help you stay mobile and improve your mood. Start slowly at first and gradually build up over a few days."

"Relaxation is known to help with pain. Examples are meditation and yoga. Try it now, sit or lie down in a quiet spot and focus on breathing in and out deeply for at least a minute. How does that feel? Other ways to do this are to listen to relaxing music, read a book or watch something good on TV.
For more information about how to manage pain, go to betterhealthpain"

Day 7, 14, 21 and 30 Check-in message for reducing opioid use at 14:00
"Hi, strong opioids are not normally needed for more than a week. It's important to reduce your use as soon as your pain improves.
Are you still taking Oxycodone, Tapentadol or Tramadol for your pain? Reply for Y or N (if you haven't)"
If patient replies Y
"Okay, there is a risk of addiction developing to opioids like Oxycodone, Tapentadol or Tramadol especially if taken for more than a few days. It's important to be careful & to switch to other ways of managing your pain as soon as you can. For more information about how to manage your pain see betterhealthpain"
If patient replies N
"Okay thanks. If you have any leftover Oxycodone, Tapentadol or Tramadol it is wise to return them to your local pharmacy for safe disposal. Your medication should not be shared with anyone. This may result in serious harm, Nell."

Day 7 Advice to return unused medicines
"If you have any leftover Oxycodone, Tapentadol or Tramadol it is wise to return them to your local pharmacy for safe disposal. Your medication should not be shared with anyone. This may result in serious harm, Nell."

Day 30 at 15:00
"Hi, did you return any leftover Oxycodone, Tapentadol or Tramadol tablets to the local pharmacy? Reply Y (if you did) or No (if you didn't), or ALL USED (if you had none left to return)."
NetPromoter satisfaction survey
"Thanks for participating. The messages from me will now end. Remember, you can speak to your GP if you are concerned - they are there to help. Take care, Nellie."

All patients (control and intervention) will receive standard clinical care and discharge medication counselling by the Pharmacy Team. Both populations will be invited to text responses to patient outcome questions according to the timed protocol via mobile text messages relating to pain, opioid use, satisfaction with Nellie and disposal of unused opioid medications via R-outcomes on the Nellie platform. R-outcomes is a family of short generic patient-reported outcome and experience measures (PROMs and PREMs respectively). PROMs are about the subject of care; PREMs are about the service provided.

The Nellie platform is a web-based dashboard for clinicians to access and manage their patients, as well as being able to be tailored at the individual patient level. Message protocols are carefully designed to promote Nellie’s supportive persona, while delivering evidence-based key messages. The interactive nature of Nellie’s programs require patients to respond to Nellie’s requests for information and reply with algorithm-generated and appropriate responses. Evidence from evaluations of the UK version of the Nellie platform (which is called “Florence”) indicate that the use of smart messaging is more effective in influencing patient behaviour than standard informational text messaging alone.

2. Legal dispensing/supply requirements of prescriptions are followed (this includes checking SafeScript)
3. Provide patient education:
• Discuss the discharge medication plan with the patient, including how long they should expect to be taking analgesia, what duration of pain relief to expect from each analgesic and the aim of therapy (e.g. to allow rehabilitation and mobility).
• Discuss the individual medications and how to take them
• Discuss what to do if they continue to have pain or their pain resolves and they don’t feel they need to take the medications
• Explain how to dispose of unwanted medication
• Provide the patient with the ‘Department of Surgery, Medication Information for Discharge’ leaflet.

Efficacy
Statistical methods / analysis
We have based our primary outcome (the proportion who are still on opioids 30-days post discharge) on previously demonstrated rates of persistent opioid use following surgery which range from 3-10%. We propose a total sample size of 700 (350 people in each arm). This would provide a 90% confidence level with 80% power, of detecting a 3% absolute difference between the groups (e.g. if the rate of opioid use at 30-days post discharge was 6% in the control group and 3% in the active group), with an additional 20% to allow for attrition.

Nellie engagement, return of unused medications, patient comfort levels and any other categorical variables can be compared using Chi squared. The satisfaction with the Nellie system and other continuous variables will be compared using Mann-Whitney U test.

Descriptive statistics will be calculated for patient demographics for comparison between the control and intervention groups.
A two-tailed p-value of less than 0.05 will be considered statistically significant.
Data analysis will be through statistical software SPSS 19.
Analysis will be carried out by study investigators. Where required, assistance from a skilled biostatistician with be employed.
Sample Size
A target of 700 enrolled patients was established using a calculator with a 90% Confidence interval, power of 80%. The reported rate of opioid use beyond 30 days post-operatively is between 3 to 10% in the literature. 350 patients will be randomised to each arm. This allows for an attrition rate of 20%. Up to 1500 surgical patients are admitted to PH per month

Summary
Brief summary
To evaluate the impact of a persona-based text-messaging service “Nellie” post-discharge on pain management and opioid use following surgery compared to standard care.

The null hypothesis is that the use of Nellie does not reduce the use of opioids post-operatively in opioid-naïve patients undergoing surgery.

The primary objective of this study is to evaluate the impact of a persona-based text-messaging service “Nellie” on the patient reported outcomes (PROMs) and opioid use after surgery compared to standard care.
Patients are invited to take part in a research project to understand if SMS text messages could be helpful to them after surgery in understanding and managing their pain. This is because they maybe prescribed strong pain medication(s) to manage pain after surgery.

Patients will receive SMS messages about managing pain once they have returned home from hospital. These messages can be about general pain information or to check-in with a choice for them to reply. The questions will ask about their pain after surgery their pain medication use and if any unused pain medications were returned to the local pharmacy.
The messages will stop at day 30 after returning home.
There will be two groups in the project; each group will be sent SMS messages at different time points. Patients will randomly be assigned to one of the two groups.
