10. Health Clinic Project
Business Case
The overall goal of the health clinic is to reduce the prevalence of Sexual Transmitted Diseases (STD). In order to optimize that goal within the clinic, we need to see as many patients as possible within maximum defined wait times while maintaining best practices.
Opportunity Statement
Our current clinician process is capable of only seeing 1.1 pts per hour, with a Full Service Patient Length of Stay (LOS) that exceeds 120 minutes.

Key Current Process Steps

A Lean Six Sigma team was formed utilizing the DMAIC (Define, Measure, Analyze, Improve, Control) methodology using both Lean and Six Sigma tools.
In the Measure phase, the team began by walking the process, then to map out the current process using both a Value Stream Mapping technique and a Spaghetti Map to better understand patient, clinician, information flows, and cycle / lead times. The team collected and validated cycle-time data, and both patient and clinician travel distance by number of steps for analysis. A Value Analysis was conducted by the team to determine and define activities that are customer value added, non-value added, and business value added; the results of this analysis were less than 2% of activities were considered to be customer value added. The customer was defined to be the patient.
Two quick-wins were identified by the value analysis that eliminated 18 minutes in the patient flow. (1) Patients with an appointment no longer went through triage, and (2) Patients forms were revised eliminating obsolete and redundant information.
By analyzing the remaining data, the team determined that the two areas impacting patient flow were in triage and the clinician diagnosis and treatment process. The actual cycle time for these two processes was 55 minutes, with a patient wait time of 82 minutes. The team’s primary focus is to identifying and validates the root cause for patient flow inefficiencies within these two primary areas.
In the Analyze phase a fishbone analysis was performed that identifying three main areas as potential root causes:
- Patient Turnaround Time
- Data Entry, and
- Lack of Clinician Teamwork/Skills
Data was gathered and used to validate these three areas by performing hypothesis testing through ANOVA.
Patient turnaround time – Clinicians that saw at least two patients in parallel, versus Clinicians only are seeing one patient at a time.
Results
Clinicians seeing patents in parallel had a significant time impact on reducing patient time and capacity.
Data Entry – Computer data entry, versus manual entry of data on form. Results: Manual data entry had a significant time impact on reducing patient time and capacity.
Clinician Teamwork/Skills – Developing an employee skills proficiency matrix the team analyzed clinicians who were more skilled / knowledgeable than other clinicians. Results: Clinicians who were more proficient had a significant time impact on reducing patient time and capacity.
Impressive Results
The clinician improvement team reduced significantly patients Length of Stay by 83 minutes. Having clinicians come up with the solutions and buy-in to seeing patients in parallel, utilizing a manual check list form (color coded for male and female), and establishing a skills proficiency matrix to improve teamwork and overall competence lead to positive outcome in identifying diseases.
The clinician’s patients per hours metric improved immediately to 2.0 pts per hour with the parallel patient flow, and progressively over time to meet the original goal of 2.5 pts per hour as clinician skills and teamwork improved. The clinicians meet for 10-15 minutes each morning to review their own dashboard, workload, and document and status issues. This Kaizen Event also establishes a meeting with the clinic leadership team and the clinicians once a month to review strategic goals and evaluate their efforts on identifying and reducing the prevalence of Sexual Transmitted Diseases (STD) in the community.
The STD clinic will be moving to a new facility in 2012 and the spaghetti mapping will be of significant support for the facility layout to reduce walking for both the clinicians and patients. In addition, the cumbersome and time consuming computer system is expected to be overhaul with input from the clinic personnel to eliminate paper forms.
