Up, up and away: The growth of after-hours MBS claims.

BACKGROUND: Media reports suggest that growth in urgent, after-hours Medicare Benefits Schedule (MBS) claims has coincided with an increasing number of after-hours medical deputising services (AHMDSs). This article assesses these claims in the context of an increasing presence of AHMDSs.

METHODS: Retrospective analysis of MBS claims data for general practitioner (GP) after-hours items from 2010-11 to 2015-16 was conducted. The Tasmanian experience is presented as a case study.

RESULTS: The number of claims was greatest for MBS item number 597 (urgent, sociable after-hours consultations), increasing by 170% over the study period. For jurisdictions with dates identified for the introduction of AHMDSs, dramatic growth in per capita claims were observed: 1270% for the Australian Capital Territory, 485% for Tasmania and 150% for the Northern Territory. For Tasmania, no decrease in emergency department presentations was observed.

DISCUSSION: Rapid increases in after-hours claims for MBS item number 597 have coincided with the introduction of AHMDSs in three jurisdictions. The impact on patient outcomes and equitable resource distribution requires attention.
