Rest home certification audits happen every 1-4 years, and a spot audit (surveillance audit) occurs around the middle of that period. Provisional audits happen after a change of ownership, and partial provisional audits happen when an owner wants to add services, such as a rest home adding hospital-level care. Auditors check a number of standards and criteria, and those that are only partially attained (PA) are graded by potential risk – negligible, low, moderate, or high – and corrective actions are ordered, with a timeframe for completion. The Herald has gathered moderate or high findings for display in this interactive. The Ministry of Health says partially attained grades don't indicate a failure, and most homes will have areas needing improvement. Rest homes must report to their DHB on how they are addressing issues found at audit. These improvements are then verified at the next audit event. The Herald gathered audit information for reports published since 2016 from publicly-available documents on the ministry’s website. This data gathering happened from January to March.
