Final answer:
Blanca, an OT supervisor, uses a histogram and cumulative percent calculations to create a Pareto chart for identifying the primary sources of discharge planning documentation issues.
Step-by-step explanation:
The core issue described involves Blanca, an OT supervisor, who is looking to address the high number of complaints regarding the OT team's discharge planning documentation. By creating a histogram to see the frequency of missed documentation and then calculating the cumulative percent, Blanca is employing a Pareto chart, a tool that helps prioritize problems by identifying the few critical ones that contribute to the majority of the issue. This chart will allow Blanca to determine if a specific unit, like the neuro unit she suspects, is responsible for most of the missed documentation, thus enabling targeted intervention strategies for improvement.
