Tools and methods for assessing data quality have advanced significantly over the past ten years, driven in part by the need for good HIV/AIDS data to inform programs. However, most of the existing tools focus on aggregate data at sub-national levels with very few measuring the quality of data at the primary source— at the individual patient record level.
The LQAS Triage System, a tool and guidelines for district level supervisors to facilitate checks at health facilities to determine the quality of a set of records (e.g., for a given health intervention at a health facility) based on a small sample of those records. Using a ‘classification’ method, Lot Quality Assurance Sampling or LQAS, a small subset of records are sampled and evaluated for coherence/completeness. The results are then compared with a predetermined threshold of quality to identify ‘acceptable’ or ‘unacceptable’ quality for the larger record set, or ‘lot.’
