Define the problem

Taking measurements

Analyze collected data

Recommend improvements

Discuss control methods

Abstracts for quality auditing from patients with the following conditions:

CHF, AMI, Stroke, CAP, SCIP, VTE, outpatient SCIP, outpatient AMI/Chest Pain

Time from patient discharge to complete chart abstraction is known to exceed requirements.

◦ Board of Directors interested in getting more timely quality reporting.

◦ Patient care cannot adapt quickly if reporting is delayed.

Requirements

Cycle time requested: 30 days

Maximum time: Abstracts completed by the 15th day of the month following discharge. (Maximum 45 days)

Allowances

Papers scanned into charts 2 days

Physicians to sign-off charts 30 days

IS to send reports to QR 30 days

Designed small Ad-hoc query in quality

database system.

Exported needed data to Excel showing date

stamps of discharge date and completed

Cycle time is outside of required limits

July ◦ Median days 60

◦ Maximum days 84

August ◦ Median days 56

◦ Maximum days 79

Nothing is happening within 30 days

It was determined earlier that IS ran the reports sending the data from the charts into the reporting system only once per month.

Improvement: Increase frequency of reporting to once per week by pulling data from another system.

Cycle time is just outside of required limits

August ◦ Median days 56

◦ Maximum days 79

September ◦ Median days 35

◦ Maximum days 54

21 day increase in cycle time

In order to accurately chart and control this process the following 5 data points must be available to the Quality Department. ◦ Discharge date

◦ Paper charts scanned date

◦ Chart sign-off date

◦ Reports run / available for abstraction date

◦ Abstraction complete date

Currently only discharge date, and abstraction date are available to Quality Reporting.

Institute checks of process using newly available data points to check for future conformance, and greatest bottleneck.

Six Sigma Future Project: ◦ Collect future data based on 5 data points, create

and maintain control and distribution and pareto charts.

◦ Identify any processes that need improvement to eliminate or smooth saw-tooth pattern based on future data collection.
