Determining patient attendance, access to interventions and clinical outcomes in a publicly funded obesity programme: Results from the Canberra Obesity Management Service.

Multi-disciplinary specialist services have a crucial role in the management of patients with obesity. As demand for these services increases, so too does the need to monitor individual service performance and compare outcomes across multiple sites. This paper reports on results from the publicly funded Canberra Obesity Management Service. A descriptive observational study was conducted on new patients who attended an initial medical review from July 2016 to June 2017. Baseline characteristics, comorbidities, attendance, service utilization and outcomes were collated until June 2018. Of the 162 patients identified, 64% continued to attend beyond initial medical review. Dietetics was the most commonly accessed allied health service, followed by exercise physiology and psychology. Very low-energy diet was the most commonly trialled intensive intervention, followed by pharmacotherapy and bariatric surgery. Mean baseline weight for those who continued beyond initial medical review was 142.0 kg (SD 26.6 kg), with a mean weight change of -6.2 kg (SD 10.2 kg) and a mean change in percentage body weight of -5% (SD 7%). Clinically significant weight loss was achieved in 36% of these patients, with a further 47% achieving weight stabilization. Mean Depression, Anxiety and Stress Scale scores reduced from 8-6-8 to 7-5-5, and mean Epworth Sleepiness Scale scores decreased from 8/24 to 6/24. Polysomnography referrals were made for 37% of all new patients, 87% of whom were diagnosed with varying degrees of obstructive sleep apnoea. We present these findings in the hope that they may serve as an example for data collection, individual service monitoring and comparison across multiple obesity services.
