General The following general screening criteria can be applied to screen available standards for implementation with within a solution. It is assumed that the standards in use with existing systems participating in the solution will be evaluated as part of the initial screening, as well as options for resolving any differences between existing, implemented standards and those selected.

Fit for purpose criteria is used to evaluate the appropriateness of the a standard for within the intended business, clinical and technical context by considering whether the standard: aligns .
Aligns to the
eHealth Blueprint; is an existing standard; supports the business requirements; supports the technical requirements; is likely to be adopted; and supports coded and free text content. [Office1]
Table 1 - Fit for Purpose Criteria
Criteria
Description
Rationale
Alignment to the eHealth Blueprint
The purpose of this criterion is to assess whether the standard supports the exchange of information between two or more components of the EHR. The standard should also be intended to be used in a federated approach to EHR architecture where multiple organizations are expected to build, operate and/or host the various applications.
The standard supports eHealth mandate in providing a single, harmonized, coherent province-wide EHR.
Existing Standard [RB2]
This criterion assesses whether the standard is adopted/adapted from existing standards, and whether it is intended for international, pan- Canadian.
Digital Health Blueprint
Selection of existing interoperability specifications and terminology subsets which have been deployed to support similar use cases improves compatibility between solutions, supports rapid project delivery and decreases speed to value.
Selection of standards which are health care delivery setting independent can be reused across multiple health care delivery settings.

Reuses an Existing, Shared Standard
Reuse of widely adopted standards across different interoperability specifications or terminology subsets allows reuse of code,
Re-use of existing standards allows implementers to re-use code (i.e. in point of service /Health Information Access Layer (HIAL)applications, conformance testing environments, etc.
). ItThis also allows reuse of existing tools/skills/knowledge sets to establish the standard.
Supports Business Requirements

---|---|---|
| ||
|
Business Requirement Support
Selected standards must address all in-scope business requirements or be adapted to meet project needs.
Expand | ||
---|---|---|
| ||
|
This criterion assesses whether the standard expresses all information required by the business/clinical domain. While the exact business requirements are project specific, example questions may include:
Does the messaging standard
|
To ensure that the standard addresses the health care business requirements.
The standard should be health care delivery setting independent to enable use across multiple health care delivery settings.
Supports Technical Requirements
This criterion assesses the degree to which the standard isStandards selected must be feasible to adopt and implement according to the technical requirements and constraints of the project.
While the exact technical requirements are project specific, example questions may include:Expand | ||
---|---|---|
| ||
|
To enable successful implementation of the standard.
Likely to be Adopted[Office3]
Likelihood of Adoption
Standards that are adopted and incorporated into solutions, either by vendors or other implementers, have better staying power in the market and offer a greater opportunity to provide value back to implementers through future integrations. Implementation costs associated with widely adopted standards may also be lower.
Expand | ||
---|---|---|
|
|
|
To ensure success of the implementation. If the standard is not widely implemented or supported by vendors, it will result in increased time, cost, and effort.
Appropriately supports coded, structured and free text content
Different standards support different data structures and levels of terminology coding. These difference entail trade-offs to application developers and users. At one extreme, end users may resist using an application which forces them to enter data in too many fields, increasing their time/effort to produce documentation. At the other extreme, just capturing free text can contribute to privacy breaches and present a barrier to implementing decision support.

Supports coded and free text content.
This criterion assesses the degree to which coded data is required.
Some questions to ask when assessing whether there is a need for coded data versus free text, may include:
|
|
|
At one extreme, end users may reject using the application because it forces them to enter data in too many fields, increasing their time/effort to do so. At the other extreme, just capturing free text can cause privacy breaches and be a barrier to implementing decision support.

Stewardship criteria facilitate support comparison of the standard‘s potential standard’s steward in terms of governance structure, licensing and intellectual property rights, and defined maintenance process.
Table 2 - Stewardship Criteria
Criteria
Description
Rationale
These criteria are associated with total costs of ownership and the future availability of the standards selected.
Costs and Benefits of Implementation
This criterion assesses whetherIs the cost of implementation and disruption to current business
isaffordable given the expected benefits
. It? It is important to consider not only the initial cost but the on-going cost for maintenance as well. Cost is not only measured in currency, but can be in time or effort as well.
Some sample questions to ask when assessing the costs and benefits of implementation, include:
Expand | ||
---|---|---|
|
|
|
|
|
|
|
|
|
|
To take into consideration any cost constraints when adopting a standard, as well as initial implementation and longer-term maintenance costs.
Governance Structure
The purpose of this criterion is to assess whether or not the standard is governed appropriately. When assessing if a governance structure is in place, it is important to consider whether there are:
|
Governance Structure
Well governed standards have processes in place for the voting, maintenance and changing of the standard amongst its various stakeholders; as well as certification and other capabilities of the standards development or maintenance organization.

---|---|---|
| ||
|
|
|
|
Intellectual Property and Licensing
CostsThis criterion assesses whether the intellectual property and licensing terms for the standard allows the wide use of the standard. Example questions may include:Intellectual property policies, licencing terms and licensing costs can impact standards uptake.
Expand | ||
---|---|---|
| ||
|
|
|
|
To ensure that the standard is vendor neutral and allows for the wide use of the standard. Openness and intellectual property policies affect the status, uptake and implementability of specifications, especially in the long term.
Defined Maintenance Process
Maintenance Process
Business requirements and technology change over time and, as such, standards need to evolve to meet changing needs. It is therefore important to ensure the selected standard has defined maintenance processes in order to evolve. There are also costs and benefits associated with the frequency of maintenance cycles and content changes.
Expand | ||
---|---|---|
| ||
|
This criterion assesses whether or not the standard custodian has processes in place to accept requests for change to address errors or new needs in the standard. When assessing if a maintenance process is in place, it is important to consider the following:

Standard quality criteria evaluate relate to the overall calibre of the standard and are not related to the standard content itself. They must enable measure the level of interoperability, be adaptable, and stable. Additional implementation resources must exist, adaptability, and stability provided by the standard as well as the availability of supporting resources such as training, implementation guides, and software to support development, conformance testing, and maintenance of the standard.[Office1]
Table 3 - Standard Quality Criteria
Criteria
Description
Rationale
Implementation Support and Education
[Office2]To assess the degree to which resources are able to assist with appropriate use and implementation of the standard. Some key questions to consider when assessing this criteria are:
Services which support implementers may help increase the rate of adoption and/or decrease the implementation and ownership costs for projects who would otherwise have to provide support services to adopters directly. These services may be provided by the custodian or service providers for a fee or free of charge.

Enables Interoperability
The purpose of this criterion is to assess whether the standard is complementary toExisting and new clinical solutions will need to exchange information in a seamless manner. Standards which are complementary to – or strategically positioned to work with – existing interoperability standards implementations
. When assessing this criterion, the following should be considered:may offer greater flexibility or long term benefit.
(Note that greater flexibility can also increase solution complexity. It is important to consider how different components of an integrated solution will interoperate with one another and requirements for supporting services when evaluating this criterion.)
Expand | ||
---|---|---|
| ||
|
|
To enable existing and new clinical solutions and provide the capability of exchanging information in a seamless manner. To ensure that previous data and legacy systems are compatible with the standard and can be upgraded if necessary.
Implementation and Maintenance Tools
This criterion assesses the availabilityThe existence of tools
,and code libraries
, and/or COTS products to support implementation and maintenance of the standard. The following are questions that may be asked:that are easily accessible or commercially available can reduce the effort and cost required to implement and maintain a particular standard.

Conformance Testing Methodologies and Tools
This criterion assesses if the standard has well defined conformance testing processes and supporting tools. Examples questions may include:Conformance criteria and profiles are used to test whether a standard has been implemented correctly. Process to measure solution conformance may already be in place and available to support the project.
Expand | ||
---|---|---|
| ||
|
In order to test whether a standard has been implemented correctly, a set of conformance criteria and profiles against which a standard can be measured is important. Ideally, a process to measure conformance should be in place to publicly notify those vendors that are certified (meet testing criteria).
|
Stability
Standards which are stable and widely implemented are more attractive for other implementers to adopt. Less mature standards may be more volatile and fragile.
Expand | ||
---|---|---|
|
Proven Stability [Office5]
|
|
|
|
If a standard is stable and widely implemented it is more attractive for other implementers to adopt it.
If a standard is still in inception, it is more volatile and fragile, which will likely lead to increased risks (e.g. increased implementation costs and timeline delays) for initial implementers.
|
Adaptability
Different standards allow implementers different levels of flexibility to make modifications to support local needs.
(Note that greater flexibility can also increase solution complexity. It is important to consider how different components of an integrated solution will interoperate with one another and requirements for supporting services when evaluating this criterion.)

For every interoperability standard, it is essential to describe how tightly the aspects defined in the standard constrain the options for the implementation, and which aspects are left for the implementation-specific or customer-specific conventions.
