Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: a brief intervention for obesity.

This 'brief intervention' will involve a 5-10 minute private conversation between the patient and their doctor in hospital which is integrated into their existing interaction during their hospital admission (timing at the discretion of the doctor) or during the pre-admission clinic consultation. :
1) Informing the patient of their weight and diagnosis of obesity.
2) Providing a pamphlet (developed by the Nutrition and Dietetics Department at The Alfred) which contains educational material on the problem of obesity, basic advice on weight loss and links to community resources (LiveLighter.com and The Alfred website to a page also developed by the Nutrition and Dietetics Department).
3) Advising the patient to see their GP for further support
4) Informing the patient's GP of the diagnosis of obesity via discharge summary or letter

Medical staff involved have been instructed that the objective of the conversation is to prompt the patient to take further steps following up with weight management post-discharge.

Control group will receive standard care during their hospital visit. Patients are routinely weighed by nursing staff so if obesity is identified, they are alerted that this is a risk to their health and advised to seek further support from their GP.

Outcomes
Primary outcome [1] 302226 0
Proportion of participants who have commenced a weight management attempt.

Assessed by online or phone survey asking:

- if patient has newly attempted weight management (yes or no)
- if yes, what strategies they have tried (diet, exercise, referral to allied health such as dietitian/exercise physiologist, pharmacological agents, referral for bariatric surgery, other)

Efficacy
Statistical methods / analysis
Power calculation:
We estimate that if 5% of patients have a discussion with their GP about their weight following discharge in the control group and we are able to increase this to 20% with the brief intervention this would be clinically significant. To detect a difference of this magnitude with a two-sided a of 0.05 and power of 0.8 we would require 75 patients in each arm. Allowing for a 15% drop out rate, we aim to recruit a total of 174 patients.

Data anaylsis:
Standard statistical tests will be used. For primary endpoints categorical outcomes (yes/no) will be analysed using fisher exact or chi-squared test, adjusting for baseline imbalances and potential covariates . Logistic regressions will be used for continuous outcomes (weight).
