Summary of Trends Across National Quality Strategy Priorities

Number and percentage of all quality measures that are improving, not changing, or worsening through 2012, overall and by NQS priority

Key: n = number of measures.

Note: For most measures, trend data are available from 2001-2002 to 2012. For each measure with at least four estimates over time, weighted log-linear regression is used to calculate average annual percentage change and to assess statistical significance. Measures are aligned so that positive change indicates improved access to care.

• Improving = Rates of change are positive at 1% per year or greater and statistically significant.
• No Change = Rate of change is less than 1% per year or not statistically significant.
• Worsening = Rates of change are negative at -1% per year or greater and statistically significant.

• Nearly half of Patient Safety measures improved compared with 60% of all quality measures.

Summary of Trends Across National Quality Strategy Priorities

Average annual rates of change of quality of care measures through 2012, by National Quality Strategy priority

Key: n = number of measures.

Note: Large red diamonds indicate median values. For each measure with at least four estimates over time, weighted log-linear regression is used to calculate average annual percentage change. Measures are aligned so that positive change indicates improved quality of care.

• Median change in quality was 3.6% per year among measures of Patient Safety.
