Evaluation of a Hub-and-Spoke MoC for the Delivery of Sleep Disorder Services

Aim

To evaluate a Hub-and-Spoke design for providing sleep disorder services in a very remote community. The health service re-design aimed to provide unattended polysomnography at the Spoke site with access to attended laboratory studies at the Hub when clinically indicated.

Outcomes

Main Outcomes Measures: Referral numbers (Reach), travel avoidance and consumer satisfaction (Effectiveness), number of referrers (Adoption), unattended sleep study data quality, timeliness to testing, health service costs (Implementation), and referral numbers beyond initial 12-month pilot (Maintenance).

Background

A public hospital in metropolitan South-East Queensland with a comprehensive accredited sleep disorder service (Hub), networked to a Community Health Centre (Spoke), located in a very remote region defined by the Modified Monash Model in central Queensland.

Discussion

Hub-and-spoke designs for public sleep disorder services are effective at both the individual and organisational levels. Services can be delivered at a lower cost and, importantly, improve access to specialist services in remote and very remote communities.

Results: The Hub-and-Spoke model increased adoption five-fold by local referrers and resulted in a nine-fold increase in reach. Effectiveness was demonstrated through high levels of consumer satisfaction, and all implementation aims were met, including providing services at a lower cost. Sustainability was demonstrated through ongoing referrals and the transition of the model of care to business as usual.
