Background: Previous estimates for the prevalence of musculoskeletal conditions (MSK) and chronic pain in Australia have been based on self-report. We aimed to determine the prevalence and distribution of arthritis, chronic back pain, gout, osteoporosis, spondyloarthropathies and rheumatoid arthritis and current consultations for chronic pain among adults attending Australian general practice, and describe their distribution according to sociodemographic characteristics and presence of co-morbidities. Methods: We investigated 1,501,267 active adult patients (57.6% females; 22.5% >= 65y) evaluated between 2013 and 2016 and included in the MedicineInsight database (a National Prescribing Service MedicineWise program), a large general practice data program that extracts longitudinal de-identified electronic medical record data from 'active' patients in over 550 practices. Three main groups of outcomes were investigated: 1) prevalence of arthritis, chronic back pain, gout, osteoporosis, spondyloarthropathies, and/or rheumatoid arthritis between 2000 and 2016; 2) current diagnosis/encounter for the same conditions occurring between 2013 and 2016, and; 3) current consultations for chronic pain of any type occurring between 2013 and 2016. Results: The combined prevalence of the investigated MSK (diagnosis between 2000 and 2016) among adults attending Australian general practice was 16.8% (95% CI 15.9; 17.7) with 21.3% (95% CI 20.2; 22.4) of the sample consulting for chronic pain between 2013 and 2016. The investigated MSK with the highest prevalence were arthritis (9.5%) and chronic back pain (6.7%). Patients with some of these MSK attended general practices more frequently than those without these conditions (median 2.0 and 1.0 contacts/year, respectively). The prevalence of the investigated MSK and current consultations for chronic pain increased with age, especially in women, but chronic pain remained stable at 22% for males aged > 40 years. The investigated MSK and chronic pain were more frequent among those in lower socioeconomic groups, veterans, Aboriginal and Torrent Strait Islanders, current and ex-smokers, and patients with chronic obstructive pulmonary disease or heart failure. Conclusions: The investigated MSK are more frequent among lower socioeconomic groups and the elderly. Based on information collected from adults attending Australian general practices, MedicineInsight provided similar estimates to those obtained from population-based studies, with the advantage of being based on medical diagnosis and including a national sample.
