You work for Broncoville General Hospital and are in charge of
tracking patient falls throughout the hospital. Recently, you have
noticed a sharp increase in the number of falls across all
departments. Upon further investigation, you have been unable to
pinpoint a single common theme other than staff under-estimating
the severity of fall risk.

The 2006 Johns’ Hopkins Fall Risk Assessment Tool is considered
the “gold” standard in hospital-based health care for fall
assessment. Broncoville General is currently using the Fall Risk
Assessment and Screening Tool (FRAST). In light of your
investigation into recent falls, you choose to compare your data to
the 2006 Johns’ Hopkins Tool.

You review your fall data for the last six months from January
2012 to June 2012. There were 76 falls hospital wide. You
investigate each incident and reassess using the 2006 Johns’
Hopkins Fall Risk. You find the following: Of the 64 patients who
were truly high fall risk and fell, the FRAST tool positively
identified 22. Of the 12 patients who were truly not high risk and
fell, the FRAST tool correctly identified five patients as truly
negative (not high fall risk). Develop a 2 x 2 table.

Calculate the Positive Predictive Value (PPV) _____

Calculate the Negative Predictive Value (NPV) _____

Calculate the sensitivity _____

Calculate the specificity _____

Would you recommend keeping the FRAST? Answer YES or NO (all
