1. Pediatric Surgery Clinic
Data Analysis
Are medical scribes effective in the
outpatient setting?
Scribe Impact for providers:
Sanjay Krishnaswami, MD, Mark
Silen, MD and Garret Zallen, MD

2. Analysis & Methods
Utilizing financial data, the analysis pulls from five months of visit/billing data at the Doernbecher
Pediatric Surgery clinic when the scribe was in the office and out of the office. We considered
both new and established patients, and divided the date per provider based on their varying
methods for closing encounters and utilizing the scribe.
• Period of analysis: May 1, 2012 – September 30, 2012
We considered the following questions:
• Are encounters closed faster with a scribe?
• Is the clinic billing at a higher CPT code with a
scribe?
• Has patient volume increased with the scribe?

Considerations
Sanjay Krishnaswami 12.7 patients 3.6 patients
Majority of
Krishnaswami’s patients
seen with the scribe in
clinic, only 9 days of the
five months was he
without the scribe.
Mark Silen 9.3 patients 7.7 patients
Garret Zallen 8.6 patients 8.2 patients

13. Conclusions
• Encounter closures: On average, Zallen and Krishnaswami closed
encounters sooner on days they did not have a scribe. Silen appears to
benefit from the scribe in this respect, closing encounters much later on
days he did not have the scribe.
• CPT Codes: Comparing clinic days with the scribe and without the scribe, it
is apparent that they lead to greater level 3 and level 4 billing (99213,
99214).
• Patient Volume: Daily patient volume was averaged per provider with and
without the scribe. All providers saw more patients on the days that the
scribe was present.
