Objectives and Scope of this Discussion

• Stage 1 of meaningful use includes some requirements to exchange identifiable clinical information among providers for treatment purposes -- we expect that the exchange requirements will increase in Stages 2 and 3

• We focused on a trust framework for information exchange between EHR systems

• We need to validate that the organization is who it says it is (digital credentials)– Does the organization really exist, and how can we gain

assurance that someone else isn’t spoofing or assuming the organization’s identity?

3

Objectives and Scope continued

• We are evaluating these trust rules at the organizational or entity level, and as such, the scope of this recommendation does not include authentication of individual users of EHR systems  

• With respect to individual users, provider entities and organizations must develop and implement policies to identity proof and authenticate their individual users (already required under HIPAA Security Rule)

Authentication Environment

5

Authentication Infrastructure

• On the Internet, the identity of an entity is authenticated using a digital certificate– Contains information about the entity– Contains public (freely published) encryption key that, when

used in combination with its paired private key (retained by the entity), can be used to authenticate the identity of the certificate holder

• The process of assigning a digital certificate to an entity is called credentialing

6

Overall Comments

• We want a high level of assurance that the organization is who it says it is– We also want to ensure an appropriate balance between level

of assurance and cost and burden of implementation

• Entity authentication (through digital certificates) is not the sole measure of security – it is necessary but not sufficient

• We assume that recommendations from the Governance workgroup will form the foundation of an accountability infrastructure for assuring adherence to a framework of privacy and security practices and policies

7

Recommendation 1: Which Provider Entities Should be Issued Digital Certificates

• All entities involved in health data exchange should be required to have digital certificates – Examples of these entities might include:

• Covered entities • Business associates• PHR providers• Public health entities• PBMs• Retail pharmacies• DME suppliers• Laboratories• Imaging centers• Non-providers--payers, claims clearinghouses, HIOs

[Note: an entity might have multiple entry points]

8

Recommendation 2: Requirements to be Issued Digital Certificates

9

Recommendation 3: Process for Issuing Digital Certificates and Process for Re-evaluation

10

Recommendation 4: Characteristics of Who Can Credential/Issue Digital Certificates

• Any entity willing to assume attendant risks (i.e., be held accountable for achieving a high level of accuracy/assurance) and meet established standards can issue digital certificates

• We recommend that ONC establish an accreditation program for reviewing and authorizing certificate issuers– Annual credentialing of entities is not enough – credential issuers

must be required to operate with transparency so their operations can be monitored and problems are quickly identified

• This requirement for accreditation should be evaluated in the context of recommendations from the HIT Policy Committee’s Governance Workgroup

11

Recommendation 5: EHR Certification and Standardization of Digital Certificates

• ONC, through the Standards Committee, should select or specify standards for digital certificates (including data fields) in order to promote interoperability among health care organizations.

• EHR certification should include criteria that tests capabilities to retrieve, validate, use, and revoke digital certificates that comply with standards

12

Recommendation 6: Types of Transactions Requiring Certificates

• Authentication is required on any transaction: – When the content of the exchange must be protected (due to

personally identifiable health information)

– When the identity of the sender and/or receiver must be known and validated

– In some cases may only need to authenticate one end versus both

• Examples of transactions that may require authentication of sender and/or receiver need assurance include:– Transactions that contain personally identifiable health information or

may otherwise pose a risk to the patient if the information is not used in an appropriate manner

– Transactions that would normally be authenticated outside of health care

– Bulk transactions used to transfer multiple patient records
