Objectives

Introduce a concept that augments the
admission process by improving:




Admission wait times
Patient satisfaction
Quality
Cost Effective Care
Explain how change was implemented
 Discuss results
 Compare results to current literature

Introduction—Lean Flow

Business concept that is well known and
implemented daily by successful
businesses

Often ignored in the healthcare industry

Gaining recognition in healthcare

Can make healthcare efficient and improve
quality
Introduction

ED overcrowding is associated with worse
quality of care and service delivery quality (1);

Recent studies have shown clearly that wait
time directly affects patient satisfaction (1-9);

Time to evaluation can also influence whether
or not a patient is seen at all (1, 2, 10).
Hypothesis

Utilizing lean flow will improve the admission
process at Sisters of Charity Hospital by:
 Decreasing the total admission process time
 Improving patient satisfaction
 Enhancing quality
 Improving Cost Effective Care
Methodology

Implementation of Lean Flow
 X32 Healthcare ‘Rapid Improvement 3-day
Program’
○ CHS Staff;
○ Four Residents;
○ Lean Flow Education;
○ ‘Front end’ Improvements;
○ Little focus on admission process
Methodology
Applied concepts to improve admission
process
Key Changes:
○ Admission Orders within 30 min;
○ ED Holding Orders in certain situations;
○ Earlier Bed Search;
○ Easier access to order sets, charts and labels
Methodology


Results—Time Variables

Summarized using means and standard
deviations.

An independent two-sample t-test using
assumption of equal variances was used to
test for differences in means.

A multiple regression model was used to
test for differences adjusted for baseline
variables (age, gender, race, Arr Method,
and Bed Type).


Summarized using frequencies and
percentages.

A Pearson chi-square test was used to compare
the proportion of satisfaction between pre and
post.

Odds ratio and corresponding 95% confidence
interval was calculated.

Discussion

Yale-New Haven Hospital utilized lean and
reduced the time from decision to admit [TAPI] to
transfer to floor [departure] by 33% (11)
 Anecdotal recount
 We had a 31% reduction of this time frame.

Lack of studies focus on admitted patients.
 Lack of focus on admission times, affect of overall
hospital rating after admission
 Limited investigation on inpatient quality.
Conclusion

Our study fills void
○ focus on how lean affects the admission process and
subsequent hospital stay.

Implementing Lean Flow at Sisters Hospital




Significantly Improved Admission Times
Significantly Improved Patient Satisfaction
Significantly Enhanced Quality
Facilitated Cost Effective Care
Conclusion

Further improvements are possible
 Focus on specific time intervals
 Re-evaluate processes

Lean Flow works and is an essential tool
implement in healthcare.
