In 2012, about 50 000 Australians had a stroke (cerebrovascular accident (CVA)).1 The risk of stroke is associated with increased age, previous stroke or transient ischaemic attack, hypertension, smoking, diabetes mellitus (DM), hypercholesterolaemia and atrial fibrillation/flutter (AF).2 Australian general practice data from the national BEACH program between April 2000 and March 2013 inclusive (1 276 200 GP–patient encounters) were analysed to determine the patient characteristics, associated conditions and management options at those encounters where a CVA was recorded, and detect changes in the annual management rates of CVA, AF, lipid disorders (LD), DM and hypertension. 

During this period, the sex-specific proportion of CVA managed (% encounters) was significantly lower in women (0.16%; 95% CI: 0.15–0.17) than in men (0.24%; 0.23–0.26). The age-specific proportions of CVA managed were 0.68% (0.63–0.73) for patients aged ≥75 years and 0.35% (0.32–0.38) for those aged 65–74 years, compared with 0.19% (0.18–0.20) for the whole sample. Comorbidities most often managed with CVA were hypertension (17.6% of other problems), DM (7.4%), LD (4.7%), depression (4.0%) and AF (2.7%).

On average, for every 100 CVA problems managed at an encounter, 60.2 medications (56.2 prescribed, including 9.0 vitamin K antagonists), 18.2 clinical treatments (including counselling), 5.1 medical specialist referrals (including 2.2 to neurologists) and 4.7 allied health referrals were recorded. Figure 1 shows that the percentage of encounters at which a CVA was recorded was constant: 0.2% for each year throughout the period 2000–2013, despite the significant increase in the proportion of older patients in the population over the past decade.3 Over the same period there were significant increases in the proportion of encounters where AF or DM were managed, whereas the proportion with LD or hypertension was variable. These findings are consistent with the effective prevention and management of CVA in Australian general practice.
