4,000 Clicks Per Shift: What the Research Says About Physicians and the EHR

Emergency physicians average 4,000 mouse clicks during a 10-hour shift. Ambulatory physicians spend more time logged into the EHR than they spend face-to-face with patients. This has been measured, published, and replicated. Here's the data.

The landmark study: 4,000 clicks per shift

In 2013, researchers at St. Luke's University Health Network published a time-and-motion study in the American Journal of Emergency Medicine that would become the defining benchmark for EHR burden research. The study — "4000 Clicks: A Productivity Analysis of Electronic Medical Records in a Community Hospital ED" (Hill, Sears & Melanson) — tracked 16 emergency medicine physicians over 30 hours of observed shifts.

The findings were stark:

Patient volume directly drove click count: physicians averaged 320 clicks per hour at 2.0 patients per hour, rising to 400 clicks per hour at 2.5 patients per hour. The EHR wasn't a tool used during care — it was the primary activity consuming the shift.

The patient-engagement cost

A 2014 study published in the Journal of General Internal Medicine (Street et al., "Keystrokes, Mouse Clicks, and Gazing at the Computer: How Physician Interaction with the EHR Affects Patient Participation") took the question further. Across 32 physicians and 217 outpatient encounters, researchers found a statistically significant relationship between computer interaction and patient silence.

High keyboard and clicking activity directly triggered conversational silence and reduced patient engagement (p=0.02). Every time a physician turned to the keyboard, the patient stopped talking. The data confirmed what physicians already felt: the EHR doesn't just consume time — it interrupts the visit itself.

What "active EHR time" actually means

In 2020, a validation study published in the Annals of Internal Medicine (Melnick, Sinsky et al., "Physician Time Spent Using the Electronic Health Record") established the formal informatics standard for measuring actual computer work vs. idle screen time. Researchers observed 337 physicians across 5 health systems, comparing direct observation against backend audit-log telemetry.

"Active EHR time" was defined as any minute containing:

Using this threshold, a PLOS ONE study (2020) applied the same event-log algorithms across a large community hospital system and found that physicians averaged 3.8 hours per day of active EHR interaction — representing 37% to 45% of their total daily work hours.

What Epic Signal shows in ambulatory practice

Epic Signal — Epic Systems' built-in analytics dashboard — tracks audit-log telemetry across thousands of practices to measure exactly how providers spend their time. Its findings on ambulatory clinicians are consistent with the peer-reviewed literature:

Signal breaks physician EHR time into four buckets: Notes & Letters (35–45% of EHR time), In-Basket inbox management (20–30%), Order entry (15–20%), and Chart Review (10–15%). Notes and inbox tasks account for more than 80% of after-hours logins.

The cognitive cost: navigation loops and workload

A 2017 study published in the Journal of Biomedical Informatics (Calvitti et al., "Physician activity during outpatient visits and subjective workload") tracked keystrokes, click sequences, and screen navigation during outpatient primary care visits. The researchers identified a category of "navigating clicks" — redundant looping across EHR tabs that falls outside standard data entry.

High click counts outside standard entry were strongly associated with higher physician NASA-TLX cognitive workload scores . The clicks weren't just taking time — they were consuming mental resources that should have been directed at the patient.

Where burnout comes from

The AMA's 2025 national benchmarking report — collected from nearly 19,000 physicians across 106 health systems — found that 41.9% of physicians are experiencing at least one symptom of burnout , with 42.9% reporting a "great deal of job stress."

In qualitative feedback, physicians consistently ranked four operational challenges as their primary sources of workplace stress:

The specialties with the highest burnout rates are also the ones with the highest documentation loads: Emergency Medicine (49.8%), Urological Surgery (49.5%), Hematology/Oncology (49.3%), OB/GYN (45.7%), and Family Medicine (45.0%).

What if the note wrote itself during the visit?

NoPajamaTime eliminates the post-visit documentation loop. Dictate during the visit — the note appears when it ends. No inbox to clear at midnight. No clicks reconstructing what happened hours ago.

The click count is settled science. The question is what physicians who've stopped accepting it actually changed — and whether it works.
