Section F.2 / In context

Where this filing sits in Ohio and in 2018

OCR classifies the incident as a hacking or IT incident, with the breached information held in email. Hacking/IT Incident is the type recorded on 162 of the 276 Ohio filings (59%) and on 45% of all filings submitted in 2018. Email appears on 23% of Ohio filings.

No business associate is recorded on the filing; 29% of Ohio filings do involve one. At 42,625 individuals the breach is 15 times the Ohio median filing of 2,763 and 11 times the national median of 4,000 across all 7,884 filings. It sits in the 10,000 to 99,999 band, which holds 1,938 filings.

As of 28 August 2026 the case is listed in the HHS OCR breach portal archive. OCR's closing summary of the case is reproduced in full below.

Ohio's breach notification statute (Ohio Rev. Code 1349.19) requires notice to affected residents within 45 days of discovery or notification of a breach. Its attorney general threshold: no direct AG requirement (reporting agencies at more than 1,000 residents). The HIPAA Breach Notification Rule ran alongside it: notice to affected individuals and to HHS without unreasonable delay and no later than 60 days after discovery, which is the clock that put this filing on the portal.

Multiplying 42,625 individuals by IBM's $160 customer-PII cost per record (Cost of a Data Breach 2025, the figure the site's calculator uses) gives a modelled $6.82M; the 2026 edition's $192 gives $8.18M. Both are modelled estimates with the method shown, not costs disclosed by Aultman Hospital. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 1.2 times the sector average.

Section F.3 / OCR closing summary

The portal's archived description, in full

Written by the Office for Civil Rights when the case was closed and reproduced verbatim from the HHS export.

Aultman Hospital, the covered entity (CE), reported that multiple email accounts were hacked which affected the electronic protected health information (ePHI) of approximately 42, 625 individuals. The ePHI involved included names, mailing and email addresses, dates of birth, Social Security numbers, drivers' license numbers, lab results, diagnoses, medications prescribed, and other treatment information. The CE notified HHS, affected individuals, the media, and provided substitute notice. The CE also provided complimentary credit monitoring services. In its mitigation efforts, the CE implemented additional administrative and technical safeguards and retrained its staff. OCR obtained assurances that the CE implemented the corrective actions noted.

$6.82M

42,625 x $160

IBM 2026 customer PII, $192 per record

42,625 x $192

Method: individuals affected, as reported by Aultman Hospital to HHS, multiplied by IBM's customer-PII cost per record (Cost of a Data Breach 2025 Figure 6 and the 2026 edition). No cost has been disclosed by the entity for this filing; the figure is a planning estimate, not a fact about the breach. IBM's per-record figures come from mid-volume breaches and IBM cautions against applying them to breaches involving millions of records; the site's per-record page explains where the multiplication holds and where it breaks down.

Context: IBM's average cost of a healthcare breach is $6.64M in the 2026 report ($7.42M in 2025); the global average across all sectors was $4.44M in 2025.

Portal: ocrportal.hhs.gov breach report. Statutory basis: HITECH Act section 13402(e)(4): the Secretary must post a list of breaches of unsecured protected health information affecting 500 or more individuals. Breaches affecting fewer than 500 individuals are reported to OCR annually and are not posted, so they are not on this register. Status wording follows the portal's two tabs ("Cases Currently Under Investigation" and "Archive") as of 28 August 2026; a filing moves to the archive when OCR closes the case. Modelled costs on this site are a method applied to the reported count, using IBM Cost of a Data Breach per-record figures, and are never a cost disclosed by the entity.
