Quality of Refractive Error Care in Dali, China, 2024 Standardized Patient Study

259 unannounced standardized patient visits to 67 optical services in Dali, China, in 2024, evaluating the quality of spectacles and prescriptions. Only 25.7% of dispensed spectacles and 38.8% of written prescriptions met optimal criteria. The study was conducted by Ling Lee and uses logistic regression to analyze factors like gender and service location associated with care quality.

Use Cases

• Analyzing disparities in eye care quality based on patient gender and service location (rural vs. urban) as identified in the regression analysis.
• Benchmarking the proportion of optimal spectacles and prescriptions against quality improvement targets.
• Studying the methodology and outcomes of unannounced standardized patient studies in a real-world clinical setting.

Strengths

• Includes data from 259 standardized patient visits to 67 distinct optical services, providing a multi-site assessment.
• Reports specific, calculated proportions for quality outcomes, such as 25.7% of spectacles and 38.8% of prescriptions meeting optimal criteria.
• Provides regression analysis results with odds ratios and confidence intervals, such as the reduced odds for male patients (OR:0.42).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Geographic scope is limited to Dali, China, which may limit generalizability to other regions.
• Row count is unknown, which may limit suitability assessment for certain analytical tasks.
