• Resumen

  • This is a longitudinal study of the trend and seasonality in unit-level hospital-acquired pressure ulcer (HAPU) rates from 2004 to 2011, for 5447 acute care nursing units in 733 US hospitals. Unit-level HAPU rates decreased significantly during 2004�2007 (OR ¼ 0.91, 95% CI [0.90, 0.91]) and the decreasing trend was much stronger during 2008�2011 (OR ¼ 0.84 [0.83, 0.85]). Seasonal variations in HAPU rates were strong and consistent during 2004�2008, with the highest HAPU rate in Quarter 1 (Jan�Mar) and the lowest rate in Quarter 3 (Jul�Sep). During 2009�2011, the magnitude of this seasonality was greatly reduced, and only HAPU rate in Quarter 1 remained significantly higher than HAPU rates in other quarters.
