Park Column lifts hygiene throughput where used.

The Headline

+2.7%

hygiene visits per day across the 47 GP rollout offices, year-to-date 2026 vs 2025 — measured from the PBI, not the manual form.

YTD hygiene VpD (47 GP offices)

+2.7%

21.15 to 21.72 visits per operating day. 25 of 47 offices improved.

May 2026 vs May 2025

-0.6%

Essentially flat for the month. The gain is in the YTD trend, not the latest month.

Daily-form compliance

Why we measure from PBI. The offices won't keep the manual tracking form.

What it means — in plain English

Hygiene throughput is up where the Park Column is actually used, but adoption is the ceiling.

Across the 47 GP offices that rolled out the Park Column, hygiene visits per operating day rose +2.7% year-to-date (21.15 to 21.72) and held flat in May vs last year. The biggest gains sit in the portfolios using the column most: Kassie DeCorte (+12.9%) and Nessreen Hagopian (+13.7%).

This mirrors the SGA East risk-score pilot, up year-to-date and flat-to-down for the month, two different methods landing the same way. The workflow recovers hygiene chair time where it's worked; the limiting factor now is consistent daily use across all 56 offices.

Hygiene VpD also moves with staffing and demand. This shows direction at the rollout offices, not clean attribution to the column alone.

Methodology

Step-by-step

Step 1

Take the 56 live Park Column offices (SGA West) with go-live dates from the Implementation Tracker.

Step 2

Pull completed hygiene visits and operating days per office from the Gen4 / SGA West Power BI, matched by practice name.

Step 3

Define Hygiene Visits per Day = completed hygiene visits (provider User Type = HYG) / office operating days (distinct dates with a completed visit).

Step 4

Compare May 2026 vs May 2025 and YTD Jan-May 2026 vs 2025; roll the cohort up volume-weighted.

Step 5

Segment GP vs periodontics; exclude 3 offices with no usable PBI hygiene data.

Without CDT-level appointment data we can't yet prove offices moved the right appointments, only that throughput is up where the column is used.
