Applying workflow analysis tools to assess immunization delivery in outpatient primary care settings.
BACKGROUND
As health care organizations face increasing pressure to institute quality assurance activities, the already-underfunded community clinics that treat the poor and underserved are challenged to perform these activities within tight constraints of human and financial resources. With pediatric immunizations as a marker, a workflow observation tool was used to identify causal processes affecting immunization delivery.


METHODS
Ten clinics and five private practices, located in areas designated as health professional shortage areas, participated in the study, gaining access to a tool that would have been unaffordable to them from the private sector. Trained observers followed families through the clinic, using a 127-item workflow observation form--the Observational Checklist of Patient Encounters (OCPE)--assessing discrete activities that families encountered during the checkin/pre-exam, exam, discharge, and billing processes. A convenience sampling of the targeted population--children younger than three years of age--included observations of scheduled acute, scheduled well-child, follow-up, and walk-in visits. In the feedback session, a summary of each clinic's immunization delivery patterns was presented, with an emphasis on the individual health center's operational issues.


RESULTS
The workflow observation tool was used to identify operational errors affecting both clinical and fiscal processes in each of the clinics that had not been previously apparent to either clinic management or the quality improvement (QI) teams.


CONCLUSIONS
Feedback addressed and encouraged process-oriented improvements in response to the workflow observations, which were incorporated into the clinics' QI procedures. Twelve of the 15 clinics have formed process action teams to address QI issues on an ongoing basis.
