Objective To explore measures of potentially avoidable general practitioner (PAGP)-type presentations to the emergency department (ED) of a large regional hospital in northern Queensland. Methods Linkage of an ED administrative dataset to a face-to-face patient survey of local residents (n=1000); calculation of Australian Institute of Health and Welfare (AIHW) and Australasian College of Emergency Medicine (ACEM) measures of PAGP-type presentations to the ED; and exploration of these measures with patient-perspective linked data. Results PAGP-type presenters to the ED were younger in age (median age in years: total cohort: 49; AIHW 38, P<0.001; ACEM 36, P<0.001); with the odds of having a chronic condition being less likely for AIHW PAGP-type presenters than other ED presenters (OR (95% CI) 0.54 (0.38-0.77): P=0.001)) after adjustment for age. PAGP-type presenters nominated reasons of convenience rather than urgency as their rationale for attending the ED, irrespective of measure. The number of PAGP-type presentations to the ED identified by the AIHW measure was more than three-fold higher than the ACEM measure (AIHW: n=227; ACEM: n=67). Influencing factors include the low proportion of ED attendees who had a medical consultation time of <1h at this hospital site (1-month survey period: 17.8%); and differences between the patient self-report and ED administrative record for 'self-referral to the ED' (Self-referred: Survey 71% vs EDIS 93%, P<0.001). Conclusions Identification of PAGP-type presentations to the ED could be enhanced with improvements to the quality of administrative processes when recording patient 'self-referral to the ED', along with further consideration of hospital site variation for the length of medical consultation time. What is known about the topic? PAGP-type presentations to the ED are an Australian National Healthcare Agreement progress indicator. Methods of measuring this indicator have been under review since 2012 and debate remains on how to accurately determine the measure. What does this paper add? By using patient perspective-linked data to explore different measures of PAGP-type presentations to EDs, this paper identifies issues with measure elements and suggests ways to improve these measures. What are the implications for practitioners? Measure elements of patient 'self-referral to the ED' and 'medical consultation time' require further consideration if they are to be used to measure PAGP-type presentations to the ED.

Objective The aims of this study were to: (1) use local health data to examine potentially preventable hospitalisations (PPHs) as a proportion of total hospital separations and estimated costs to a large regional hospital in northern Queensland, including differences associated with Indigenous status; and (2) identify priority conditions and discuss issues related to strategic local primary health intervention. Methods A cross-sectional analysis was conducted using Queensland Hospital Admitted Patient Data Collection data (July 2012-June 2014) restricted to 51087 separations generated by 29485 local residents. PPHs were identified from the International Statistical Classification of Diseases and Related Health Problems 10th Revision Australian Modification (ICD-10-AM) and procedure codes using National Healthcare Agreement definitions. Age-standardised separation rates were calculated using Australian 2001 reference population and associated economic costs were estimated using Australian-refined diagnosis related groups. Results Eleven per cent (n=5488) of all hospital separations were classified as PPH, and most were for common chronic (n=2486; 45.3%) and acute (n=2845; 51.8%) conditions. Because many acute presentations reflect chronic underlying disease, chronic conditions account for up to 76.5% of all PPHs. Age-standardised PPH rates were 3.4-fold higher for Indigenous than non-Indigenous people. Associated 2-year costs were AU$32.7million, which was 10.7% of estimated total health care expenditure for hospital separations, and were higher for Indigenous (14.9%) than non-Indigenous (9.7%) people. Conclusions High hospitalisation rates and costs for common preventable chronic conditions represent opportunities for primary healthcare interventions. In particular, community-level health services need to be more responsive to the needs of local Indigenous families. What is known about the topic? PPH rates are used as a measure of timely access to quality primary health care, and are incrementally higher in regional and remote areas than in major cities. Investment in primary healthcare services has been shown to significantly reduce costs associated with avoidable hospitalisations. What does this paper add? This study used local health data to identify the most common PPH conditions presenting to a large regional hospital in northern Queensland, including estimation of costs and differences associated with Indigenous status. Recommendations are made to strengthen primary healthcare and reduce hospital-related costs. What are the implications for practitioners? Interventions to address high PPH rates should be tailored to meet the needs of the local population. Primary health strategies targeting common chronic conditions provide the greatest opportunity to reduce avoidable hospitalisations and costs in this regional area. Investment in collaborative, evidence-based interventions is recommended and justified, especially for Indigenous Australians.
