ABSTRACT Introduction: Acute post-streptococcal glomerulonephritis (APSGN) significantly impacts children, particularly in remote Northern Territory (NT). This audit evaluates the completeness and adherence of public health responses to APSGN cases against local NT guidelines. Methods: A descriptive analysis of APSGN notifications from 2014 to 2023 using the NT Notifiable Diseases System (NTNDS) was conducted. Data from the REDCap database, an ancillary database for the NTNDS, for January 2022 to December 2023 were audited for accuracy and completeness, and to assess the adherence to the public health guidelines. Key metrics included timely notifications to the NT Centre for Disease Control (CDC), data completeness, and public health response accuracy. Results: Between 2014 and 2023, APSGN cases increased overall and now show a consistently higher number of notifications ongoing annually and outbreaks are not as marked a feature. REDCap data mirrored NTNDS demographics, with 80% confirmed cases. However, only 60% of notifications were timely to the NT CDC, and 55% of public health actions were completed. Notable gaps included documentation inconsistencies and incomplete follow-ups. Conclusion: This audit reveals significant trends in APSGN notifications, particularly how the disease disproportionately affects Aboriginal and Torres Strait Islander children and a sustained increase in cases is seen as opposed to periodic outbreaks. The audit has highlighted gaps in the current public health response, particularly around notification timeliness and documentation of contact tracing follow up. Recommendations include improving documentation, data collection processes and the data entry system to optimise response efforts. Addressing these issues is crucial for improving APSGN management and outcomes in at risk populations and will ensure accurate assessment of the impact of APSGN.
