Dialysis Treatment Days measures DaVita's reported count of U.S. dialysis treatment days used to interpret annual activity.

DaVita reported 313.0 days in its 2025 disclosures.

Treatment days and daily volume reconcile almost exactly to annual treatments

DaVita reported 91,802 average treatments per day.

Multiplying 313.0 days by 91,802 treatments per day gives 28,734,026 treatments, just 46 above the reported 28,733,980 annual treatments because of rounding.

A single day of average activity represented about 0.32% of annual treatment volume

Dividing 91,802 by 28,733,980 gives approximately 0.32%.

Use Dialysis Average Treatments per Day to pair the calendar denominator with activity.

Treatment days are not ordinary calendar days

Weekday mix matters because dialysis schedules are not uniform across all seven days.

DaVita therefore also uses normalized treatment-day concepts when discussing organic growth.

Where this concept fits

Treatment volume, patient base, and network footprintCurrent relationship
Treatment volume, average daily treatments, treatment days, patient count, outpatient centers, hospital service contracts, market share, and normalized non-acquired growth show the operating scale and underlying demand base. Center count and patient count are point-in-time measures, while treatments are period activity.

Reimbursement, payor mix, and care setting
Average patient service revenue per treatment shows blended reimbursement, government and commercial revenue mix show payor economics, and outpatient, home-based, and hospital inpatient revenue mix show where care is delivered. Revenue shares are not interchangeable with patient or treatment shares.

Cost, collections, and segment profitability
Patient care cost per treatment frames direct operating cost, days sales outstanding shows collections efficiency, and segment operating income shows the resulting GAAP segment contribution after the issuer's reported expense structure.
