Secondary prophylaxis and specialist review compliance in paediatric patients with acute rheumatic fever and rheumatic heart disease in a Western Australian metropolitan setting.

AIM

Rheumatic heart disease (RHD), a consequence of acute rheumatic fever (ARF), continues to cause significant morbidity and mortality in susceptible young people. Secondary antibiotic prophylaxis is an effective strategy to prevent ARF recurrence and RHD progression. However, the proportion of patients receiving the recommended minimum benzathine penicillin injections (>80%) remains low. This retrospective cohort study reviews the utility of the Hospital in the Home nursing service in providing secondary prophylaxis for outpatients in a metropolitan state capital.

METHODS

Fifty-eight patients with ARF/RHD receiving secondary prophylaxis through the Hospital in the Home service between 1 July 2012 and 30 June 2020 were included. Compliance of secondary prophylaxis, specialist review and echocardiogram frequency were compared against the recommendations from the Australian RHD guidelines.

RESULTS

Forty-six (79%) patients received >80% of recommended doses, with 36% (n = 21) receiving 100% and a further 29% (n = 17) achieving compliance of 90%-99%. We found that 35% of patients attended all specialist reviews (including echocardiography) at the recommended frequency, with 75% of those not attending all reviews, missing only one or two appointments. Compliance was greater in those with more severe disease. In the 12 (21%) patients who did not meet the >80% target, compliance ranged between 33% and 79% (mean 64.5%) and all had priority 3 disease.

CONCLUSION

Community-based administration of secondary prophylaxis through a registry-based system is an effective strategy of improving compliance within a metropolitan area and should be utilised in a culturally safe and collaborative manner to increase uptake.
