The conversion implementation consultant is a dynamic project role which includes multiple responsibilities that serve an important function towards the successful execution of a discrete clinical data conversion. It is a versatile role that requires some level of technical and logistical insight to navigate the project effectively and efficiently. The conversion IC is also one of (if not) the frontline project resources that drive to ensure integrity, accuracy, and patient safety are kept in high regard during the conversion process. Not only is the conversion IC responsible for defining, managing, and executing conversion build tasks that are functional in nature, but to also guide and inform the client towards decisions that will assist in adding optimal value and ensure a smooth transition from the legacy system. The following are some functional responsibilities of the conversion IC defined in greater detail with an emphasis on conversions from legacy systems to EHR.
Dataset Mappings
Even though most EMRs set out to fundamentally accomplish the same goals and to some extent offer similar functionality; they are understandably different in many ways. In general, target systems (converting to) do have to accommodate some level of additional build work in order to account for gaps or differential dictionary content that the source system (converting from) could potentially provide or want to convert. Identifying these gaps and helping the client to build their data set translations is a major (if not the primary) function of the conversion IC. These translations or “crosswalk” files are typically manifested in a spreadsheet or flat file and then supplied to the interface and/or integration engineers on the project to install in the inbound interface or database engine.
In general it is recommended that a clinical resource be involved in the data mapping and approval process to ensure that clinical integrity is maintained throughout the conversion process. Data elements that generally require an interface translation or crosswalk from the source system to the target system are:
Allergens (Medication & Non-Medication)
This dataset involves obtaining extracts from both the legacy and EHR system in order to generate a mapping from the legacy system to EHR. It helps to handle the medication and non-medication allergen translations as individual crosswalks. Both types of EHR allergens (medication and non-medication) can be handled as unverified if a translation cannot be established.
Codification values à NDC values can help to automate this process if supplied by the legacy system.
The EHR allergen (non-medication) dictionary can be obtained by running a SSMT extract via the allergen content category. The medication allergen EHR dictionary must be extracted from the EHR database by a technical resource and provided to the conversion IC. Any non-medication allergens provided by the legacy system that do not map or exist in the target system (EHR) would need to be built in EHR.
Medications
This dataset involves obtaining extracts from both the legacy and EHR system in order to generate a mapping from the legacy system to EHR. Due the size and complexity of most EMR medication data dictionaries it is important to consider the amount of time and clinical input required to procure, establish, and test a translation involving medications of a variety of statuses. Medications can be handled as unverified items if a translation cannot be established.
Codification values à NDC values can help to automate this process if supplied by the legacy system.
The EHR medication dictionary must be extracted from the EHR database by a technical resource and provided to the conversion IC.
Problems (includes Active, Past Medical Hx, Past Surgical Hx, Past Social Hx, Past Family Hx)
This dataset involves obtaining extracts from both the legacy and EHR system in order to generate a mapping from the legacy system to EHR. Due to the size and complexity of most EMR problem based data dictionaries it is important to consider the amount of time required to procure, establish, and test a translation involving problem entries and categories of multiple statuses; especially cases where a 1-to-many relationship between the source and target system may exist and needs to be resolved. Problems (all categories) can be handled as unverified items if a translation cannot be established.
Codification values à ICD9, CPT, and/or SnowMed values can help to automate this process if supplied by the legacy system.
The EHR problem dictionary must be extracted from the EHR database by a technical resource and provided to the conversion IC.
Vital Signs
This dataset involves obtaining extracts from both the legacy and EHR system in order to generate a mapping from the legacy system to EHR based on the code values of each vital signs component (orderable and resultable). EHR vital signs are technically enforced findings, but live in the EHR orderable item dictionary.
The EHR vital signs order and associated result codes can be can be manually retrieved from the orderable item dictionary since the number of items is manageable. Obtaining these order and result code values is recommended directly from the orderable item dictionary so that the relationship between orderable item and resultable item is kept intact otherwise this can lead to errors upon filing into EHR.
Documents (Unstructured Notes)
This dataset involves obtaining a list of document type codes from both the legacy and EHR system in order to generating a mapping from the legacy system to EHR. Converted documents are typically filed with a status of “Final – Receipt” since in most cases only finalized or verified documents are migrated from legacy systems.
The EHR document type dictionary can be extracted via the document type SSMT category and filtered to “RTF” manifestation type by the conversion IC to produce a list of potential target EHR unstructured note types. Any document types provided by the legacy system that do not map or exist in the target system (EHR) would need to be built in EHR.
Images (Scanned Images)
This dataset involves obtaining a list of document type codes from both the legacy and EHR system in order to generate a mapping from the legacy system to EHR. Scanned image file types and formats can vary in their manifestation types from system to system so it is important to understand if additional technical manipulation will be required up front to prepare the documents in a format that EHR will accept and properly display.
The EHR document type dictionary can be extracted via the document type SSMT category and filtered to “TIFF” manifestation type by the conversion IC to produce a list of potential target EHR scanned image types. Any document types provided by the legacy system that do not map or exist in the target system (EHR) would need to be built in EHR.
Immunizations
This dataset involves obtaining an extract from both the legacy system and EHR in order to generate a mapping from the legacy system to EHR. Depending on the functionality available to end users in the source system this extract is typically low to medium in terms of size and complexity. Immunizations can be handled as unverified items if a translation cannot be established.
The EHR immunization dictionary must be extracted from the EHR database by a technical resource and provided to the conversion IC. These are essentially medication entries that have entry codes starting with “CV”.
Results
This dataset involves obtaining an extract from both the legacy system and EHR in order to generate a mapping from the legacy system to EHR. Depending on the number of lab vendors and current setup of the target system (i.e., synchronization) it is important to consider time and level of clinical involvement. One of the advantages of executing the Order/Result conversion mapping is the ability for flow sheets to continue to flow historical data in a longitude format. It also prevents from having to build additional and potentially erroneous entries in the orderable and/or resultable item dictionaries just to house converted data. It is generally the case that both the orderable items and resultable items will need to be individually mapped in order to honor to the relationship between the parent orderable item and resultable components.
Codification values à LOINC or CPT codes can help to automate this process if available from the legacy system and if assigned to EHR orderable items in the Orderable Item Dictionary.
The EHR orderable item dictionary and associated resultable items can be obtained by running a SSMT extract on using the Order-Results v11 content category. The resultable item dictionary itself can be obtained by running a SSMT extract using the RID – Resultable Item Dictionary content category.
