eDHR Completion Rate at 56% right-first-time rate: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop right-first-time rate to 56%, then walk the calculation through step by step. Measure how many electronic Device History Records (eDHRs) are completed and released per review hour, adjusted for the right-first-time rate.

The inputs for this scenario

  • eDHRs completed and released: 120 records (held at the documented default)
  • Total review and approval hours: 80 hr (held at the documented default)
  • Right-first-time rate: 56 % (the input this scenario stresses; the baseline uses 78)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw review throughput = eDHRs released / total review hours.
  • Effective eDHR completion rate works out to 0.84 units/hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 1.5 units/hr at these inputs.
  • Right-first-time rate works out to 56 % at these inputs.
  • Total review hours works out to 80 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where right-first-time rate sits at 78% and the headline result is 1.17 units/hr, this scenario comes in 28.21% below the baseline at 0.84 units/hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to right-first-time rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats all eDHRs as equal effort; a complex implant batch record can take far longer to review than a simple single-component record.

Results at a glance

  • Effective eDHR completion rate: 0.84 units/hr (headline result)
  • Raw throughput: 1.5 units/hr
  • Right-first-time rate: 56 %
  • Total review hours: 80 hr
