Electronic Health Records

Worried about having to enter immunization information twice? You don't like extra work and neither do we.


The Colorado Immunization Information System can eliminate double-data entry for your practice. CIIS currently has the ability to receive and process electronic information from Electronic Health Record systems (EHRs) in the following Health Level 7 (HL7) formats:


Interface Implementation Process for Healthcare Providers

Is your office interested in establishing an electronic interface with the immunization registry?  Please review our Provider Interface Guidance Document for more details about the phases of interface implementation and how to get started.


Interface Implementation Process for EHR Vendors

Is your EHR company interested in testing an electronic interface with the immunization registry?  Please review our EHR Vendor Interface Guidance Document for more details about the phases of interface implementation and how to get started.


In the market for an EHR? Make sure it's certified! The Office of the National Coordinator for Health Information Technology (ONC) named the Certification Commission for Health Information Technology (CCHIT), the Drummond Group, Inc., and InfoGard Laboratories, Inc. as the first technology review bodies that have been authorized to test and certify EHR systems for compliance. Read more about ONC-Authorized Testing and Certification Bodies.


Contact CIIS today at cdphe.ciis@state.co.us or (888) 611-9918 #1 to begin the process of electronic batch messaging from your EHR directly to the registry!



In July 2010, the Centers for Medicare and Medicaid Services (CMS) published the final rules to implement the provisions of the American Recovery and Reinvestment Act (ARRA), allowing for incentive payments to healthcare providers and hospitals who demonstrate the meaningful use of certified Electronic Health Record (EHR) technology. Certified EHR technology used in a meaningful way is one piece of a broader health information technology infrastructure needed to reform the health care system and improve health care quality, efficiency, and patient safety.


The Medicare and Medicaid Programs Electronic Health Record Incentive Program Final Rule 1 contains the following objective and measure relating to immunization information systems in its Stage 1 criteria for meaningful use:


  • Objective: Capability to submit electronic data to immunization registries or immunization information systems and actual submission in accordance with applicable law and practice.

  • Measure: Performed at least one test of certified EHR technology's capacity to submit electronic data to immunization registries and follow up submission if the test is successful


This capability to submit electronic data to immunization information systems using HL7 (Health Level 7) messaging standards and CVX message vocabulary for identifying vaccines is one of three public health objectives that can help a provider achieve meaningful use. For more information about other objectives as well as details about the EHR incentive payment programs, please visit the CMS website.



Is your office ready to attest to attaining Meaningful Use of Electronic Health Record (EHR) Technology?

Starting in February 2011, CIIS instituted a waiting list for new providers who want to participate in the immunization registry and attest to Meaningful Use. We are moving down the list in the order in which offices were added to the queue.  It is nearly impossible for us to give you an exact timeline for when your office will be able to access CIIS as several steps in the implementation process are dependent upon providers and EHR vendors responding to us in a timely manner. Please know that we are working as expeditiously as possible, and we thank you for your continued patience.


There are several steps that you can take NOW to prepare your office for Meaningful Use attestation while CIIS works through its long waiting list.


  • Contact your CO-REC Partner Organization and ensure that they know you have selected "Submit Electronic Data to Immunization Registries" as your Public Health Objective.


  • Get on our waiting list by sending us an email.


  • Download, complete, sign and submit all required CIIS paperwork, including the CIIS Letter of Agreement, CIIS Clinic Information Form and Clinic Administrator Form. Fax the completed and signed documents to 303-758-3640 or scan and email them.



  • Download the latest version of the CIIS Health Level 7 (HL7) Version 2.3.1 Implementation Guide. It is critical that your test file be developed to meet these specifications!


Health Level Seven, or HL7, is an American National Standards Institute (ANSI) standard for healthcare specific data exchange between computer applications. "Level 7" refers to the seventh level of the International Organization for Standardization (ISO) seven-layer communications model for Open Systems Interconnection (OSI) - the application level. HL7 version 2.x (v.2.x) collectively defines a series of electronic messages to support administrative, logistical, financial as well as clinical processes. The v.2.x standards are backwards compatible, i.e. a message based on HL7 version 2.3 will be understood by an application that supports HL7 version 2.6.


The CIIS HL7 Version 2.3.1 Implementation Guide describes the content and HL7 message mapping specifications for the set of data elements utilized to communicate information to the immunization registry.


The CIIS Flat File Specifications contain information to assist you with creating an export of data from your EHR to CIIS.  We currently accept data in the following file formats: Access database, delimited text files, Excel and HL7.  Please review the Data Tables and Code Descriptions Tables included in the CIIS Flat File Specifications carefully as they answer frequently asked questions regarding the creation of flat data files as well as describe the specific data definitions that must be included in an export file for batch upload into the registry.  CIIS uses a Client table which contains demographic information and a Services table which contains information about each immunization a patient receives.
