Study type
Description of intervention(s) / exposure
The intervention arm is a shared decision making multidisciplinary team meeting. The MDT includes the patient along with any support persons they would like, an anaesthetist, surgeon, and social worker or Clinical Nurse Consultant relevant to the surgical area. Consultation with any appropriate health care professionals including the participant’s GP will occur as appropriate to each individual patient.
Shared decision involves 'choice', 'option' and 'preference' talk:
1. ‘Choice’ talk
a. Ensure there is agreement on the nature of the problem
b. Introduce the concept that more than one option exists to investigate, manage or treat the problem. There is an acknowledgement that a choice may be a non-interventional option. Explicitly acknowledging uncertainty in medicine and unpredictable outcomes is essential.
c. A key component of this section is to highlight that patient’s beliefs, values and preferences are important in working out best options
d. It is also essential to check if the patient has understood the choice talk
e. It is important at this initial stage to defer closure of the conversation so that the clinician and patient can move to ‘option talk’.
2. ‘Option’ talk
a. This may begin by checking for existing knowledge as a starting point for listing options
b. A summary list of options may be used, before exploring each option in more detail. This is a way of making sure that the patient does not miss the opportunity to learn about options that they may already have discounted.
c. The clinicians may then start by describing what each option entails. This helps to separate the description of each option from the discussion of the risks and benefits of each.
d. An essential component of this section is to then explore risks, benefits and consequences and the chances (likelihoods) of these benefits and risks actually occurring. This can take the form of, for example, describing the most relevant and common risk or consequence before describing the benefit. Part of the multidisciplinary preparation for the SDM meeting will be to individualise (as far as possible) this particular patient’s risks.
e. The option talk often includes a check by the clinicians that the patient understands what has been discussed about the options and the relevant risk/benefit explanations.
f. As above, patient preference should be woven throughout this section
3. ‘Preference’ talk
a. Whilst patient preferences/values happen throughout the SDM process, it is essential to actively enquire about the patient’s values and preferences as they assimilate information about options. This section refers to values and attitudes of the patient and not directly to the preference for a particular option.
b. At this stage, it is sometimes useful to summarise what has been done and state that it may be appropriate to make a decision at this time
c. It is important to recognise that patients may need time for deliberation before a decision is made. Some patients may wish to access more information etc
d. It may also be appropriate to help the patient to explore the options in terms of what is important to them.
e. If appropriate, patients can, at this point, state their preferences and move to make a decision

a. The MDT aims to occur as soon as possible post referral and will varied. This is due to the complexity of gathering the people that are important to attend this meeting.

b. Content of the meeting: As above - patient values, risks and benefits for ALL management options including 'do nothing'

c. The meeting will be planned for 1 hour and will be 1 face to face with phone follow up and further face to face if necessary for follow up questions

d. As above (mode of administration)

e. MDT with surgeon, anaesthetist, and social worker

f. formal training with follow up training once started. visits to other centers performing SDM. Adherence to SDM protocol (including necessary pre-work, attendance, consultations etc) will be monitored

Other interventions
Comparator / control treatment
Control group
The control is usual peri-operative care – either Consultation or Preadmission clinic depending upon referral process as described above.
No singular John Hunter Guideline exists to describe 'Usual Peri-operative care'. If a patient has a 'request for admission' submitted (ie. a request for surgery), they receive a Pre-admission appointment unless considered (after review by a Perioperative Nurse) as low risk. Various components of this Pre-admission process may involve one of many guidelines in existence such as management of diabetes.

Consultation occurs if a surgeon subjectively feels that an anaesthetist review is warranted before listing a patient for surgery.

Statistical methods / analysis
Statistical analysis- Results will be analysed using the intention to treat principle. For continuous outcomes (QoL, patient and clinician satisfaction ratings, acceptance and engagement in process) obtained at multiple time points (7, 30 and 90 days) a linear mixed model will be used to compare the repeated measures across the 2 groups, avoiding the need for multiple comparisons at each time point; mixed models are also able to handle missing data in the event that a participant does not complete a questionnaire at a given follow-up time point. The models will also include a time x group interaction term to check if the effect of the intervention differs over time, and a term for randomisation strata.
For count outcomes (days alive and out of hospital, and ICU days) a Poisson or negative binomial regression model will be used with a term accounting for randomisation strata; depending on the distribution of values, a zero-inflated model may also have to be used.
For surgery types (initial, modified, cancelled) a logistic regression will be used to compare intervention and control groups, accounting for randomisation strata.
For the Modified Glasgow Outcome scale, an ordinal regression mixed model will be used to detect if there is shift towards better functional status in the intervention vs control group at each time point adjusting for strata.
For readmissions/representations and mortality, a time to event analysis will be done using Kaplan-Meier curves, with a Wilcoxon test for early differences and a log rank test for late differences. In the event that only readmissions/representations are used as the outcome, then mortality will be used in a competing risk analysis.
Economic analysis – A within trial cost-utility analyses (CUA) will be undertaken. The analysis will be conducted from the perspective of Hunter New England Health, as the key decision maker. Resource utilisation will account for the cost of implementing and delivering the intervention, as well as patient utilisation of HNEH services. Results will be expressed via an assessment of the incremental costs and outcomes of the intervention against usual care. Quality adjusted life years (QALYs) will be calculated using the EQ-5D or ICECAP-O outcome measures, and appropriate preference-based utility weights. The analysis will report the incremental cost-effectiveness ratio (ICER). Bootstrapping will estimate the uncertainty surrounding the ICER. Uncertainty will be graphically represented on cost-effectiveness planes. Cost-effectiveness acceptability curves (CEACs) will be derived to illustrate the probability that the intervention is cost effective in comparison with usual care for commonly-accepted thresholds. The analysis will be presented alongside additional economic considerations, such as differences in patient residence within aged care institutions and any impacts upon primary or allied health service utilisation.

Brief summary
The purpose of this study is to determine if shared decision making involving the patient, medical team and their support person will be of benefit to a patient in order to identify what is really important in their life. This initially involves approximately a 15 minute telephone conversation talking about the study and what to expect at the multidisciplinary shared decision making meeting. If an inpatient, a bedside conversation will occur to discuss surgical risks and benefits and the next steps. The study centres around informed decisions about their surgery and how they would like to be cared for.

Who is it for?
You may be eligible for this study if you are older than 65 or older than 45 (if Aboriginal or Torres Strait Islander) and undergoing Major General or Vascular Elective or Semi-urgent surgery.

Study details
Patients in this study will be randomly assigned to either the control group (standard treatment) or the intervention group. Participants in the intervention group will be involved in a 'shared decision making' team meeting, involving relevant medical professionals and support persons of the patient. Part of involvement in the study will include a variety of questionnaires about surgery decision making and quality of life.

It is hoped that this research will help determine how comfortable patients feel about making decision about their healthcare and also assist the medical community in developing strategies for shared decision making.
