Objectives: To describe patterns of skin checks for potential skin cancers in general practice and subsequent skin-related healthcare, and the associated costs. Study type: Retrospective longitudinal health record linkage. Methods: Patient encounters between 2010 and 2017 were extracted from clinical information systems at 73 general practice sites in Victoria, Australia, including Medicare billing information, from the MedicineInsight primary care dataset. The main outcomes were skin checks, skin-related healthcare up to 3 months after the skin check, and health system costs. Results: There were 59 046 skin check encounters (0.7% of all general practice encounters) identified for 40 014 people with a median age of 52 years (interquartile range 36–67). Of these people, 26% had multiple skin checks. Of the subsequent skin checks, 28% were within 3 months of the initial skin check and 15% were after > 2 years. There was subsequent skin-related healthcare ≤ 3 months after 20% of all skin checks: 8% had a skin biopsy, 11% had a skin excision (of which 2% indicated a melanoma diagnosis, 29% keratinocyte carcinoma and 68% benign or other skin lesion), 2% had skin-related medicine prescribed and 5% had other skin-related treatment such as cryotherapy (not mutually exclusive). Ninety per cent of skin checks were billed as general practitioner (GP) consultations, including 65% as GP consultations of < 20 minutes although the proportion of longer consultations increased over time. The mean 3-month skin-related general practice health system costs for people without and with subsequent skin-related healthcare were A$58 and A$240, respectively, and up to a mean of A$595 for those having a melanoma excised. Conclusions: Skin checks for potential skin cancers occur frequently in Australian general practice and accumulate substantial health system costs, with one in five skin checks resulting in subsequent treatment. This study adds to scarce real-world skin check and cost data in Australia. [ABSTRACT FROM AUTHOR]

The Victorian Comprehensive Cancer Centre Data Connect is a data linkage resource in Australia that combines primary care, hospital, and cancer registry data for health services research. It contains de-identified data on over 3 million primary care patients, including clinical and administrative information such as hospital admissions, GP encounters, prescriptions, pathology test results, and cancer diagnoses. Researchers interested in using this resource can contact Data Connect. The article emphasizes the importance of data linkage in understanding patients' care journeys and mentions other linked data resources in Australia and the UK. Data access is provided by BioGrid Australia, ensuring data governance, ethics, privacy, and security. The article concludes by discussing the data collected in Data Connect and ongoing efforts to expand the resource. [Extracted from the article]
