This section provides additional guidance on the relationship between the associated profiles and the structure of the interoperable transitions of care document.
Post-acute transitions of care are critical for ensuring continuity, safety, and quality of care as patients move from one healthcare setting to another, such as from a skilled nursing facility to home health care, or rehabilitation center. Effective PAC transitions reduce the risk of adverse events, rehospitalizations, and gaps in care. Below are the important aspects of post-acute care transitions.
LTPAC transition planning is essential to ensure that patients leaving one setting and transitioning to another have a clear plan for managing their health. This includes medication reconciliation, follow-up appointments, and instructions for self-care.
Clear communication between healthcare providers across settings is critical to avoid information gaps that can lead to errors or delays in care.
Ensuring accurate medication lists and reconciling changes made prior to care transition is vital to prevent medication errors, which are common during transitions.
Patients and their caregivers must understand the care plan, including medications, follow-up care, warning signs, and how to access resources. Education empowers patients to manage their health effectively.
Timely follow-up appointments with primary care providers or specialists are crucial to monitor progress, address complications, and reinforce the care plan. Interoperable exchange of patient data across the care team is essential for care team communication and follow up.
Evidence-based transitional care models, such as the Transitional Care Model (TCM) or Project RED (Re-Engineered Discharge), provide structured approaches to improving care transitions.
Social determinants such as transportation, housing, and access to food can impact a patient’s ability to adhere to the care plan. Identifying and addressing these factors is essential.
Technology, such as electronic health records (EHRs) and telehealth, facilitates communication and monitoring during transitions, especially for patients in remote or underserved areas. Critically important technology and the impetus for this IG is human- and machine-readable interoperability from endpoint to endpoint across a national framework of networks such as TEFCA and the QHINs.
Ongoing evaluation of transition processes, including patient outcomes and satisfaction, allows healthcare organizations to identify gaps and implement improvements.
Effective post-acute care transitions requires interoperability across a national framework of networks, such as TEFCA, facilitating a multidisciplinary approach that emphasizes communication (requiring human and machine readable interoperability), patient education, medication safety, follow-up care, and addressing social determinants. Evidence-based models and interventions, such as the Transitional Care Model and Care Transitions Intervention, have demonstrated their ability to improve outcomes and reduce rehospitalizations.
By defining a standard of human- and machine-readable interoperable documentation for post-acute care transitions this IG enables healthcare providers to ensure smoother transitions, better patient outcomes, and reduced healthcare costs.
The Transitions of Care Document is structured as a container that packages the clinical information needed to support a patient's transition into a single, transmissible unit. The Transition of Care Bundle provides the linkage between the searchable document and the clinical content included in the compositor. The Transitions of Care Composition is the core of the clinical content, serving as the document's index and organizes the clinical content into a set of named sections, each covering a distinct domain of patient information. The sections defined below represent the full scope of the Composition, along with their associated LOINC codes, clinical descriptions, and usage notes to guide implementation.
Section Code: LOINC 42348-3 Advance healthcare directives
Description: Declarations by individuals made in advance of a situation in which they may be unable to decide about or articulate their wishes for their own care, stating their treatment preferences and limitations on treatment. Examples include Personal Advance Care Plans, Portable Medical Orders, Mental Health Advance Directives, Episodic Advance Directives, POLST/MOLST forms.
Usage Notes: No additional guidance beyond the description above.
Section Code: LOINC 48765-2 Allergies and adverse reactions Document
Description: List of any responses to medication, food, and topical, ingested or inhaled agent occurring with normal use that are unintended, potentially harmful, and unwanted by the individual. Allergic reactions involve the activation of the immune system in the response. Examples of adverse reactions include low blood pressure from opiates, confusion and dry mouth from anticholinergics. Examples of allergic reactions include hives, rash, and anaphylaxis.
Usage Notes: No additional guidance beyond the description above.
Section Code: local code: Behavioral Health Summary
Description: Observations, assessments, and interventions regarding the impact of behaviors on mental and physical well being. Examples of behaviors include reactions to stress, habits, substance use disorders, eating disorders, as well as mental health conditions such as anxiety, depression, psychosis, and personality disorders. Interventions include education, counseling, pharmacological and non-pharmacological treatments. Impacts on physical and mental health include legal, social, and occupational issues, as well as physical impacts from behaviors such as sedentary lifestyles.
Usage Notes:
This section should not include diagnoses or medications. Diagnoses should all be in the TOC Problems section. Medications should all be included in the TOC Medications section. Ideally, Medications should be linked to the problem for which they are indicated. The diagnosis “Depression” is listed in the US Core Plan, but should not be included here.
Section Code: LOINC 47420-5 Functional status assessment note
Description: Observation, assessments, and interventions regarding basic physical and cognitive activities and their impact on mental and physical well being. Examples of observations and assessments include those of mental status, mobility, activities of daily living, speech, and swallowing. Examples of interventions include devices, therapy, and modification of the environment including personal assistance.
Usage Notes:
This section should not include diagnoses or medications. Diagnoses should all be in the TOC Problems section. Medications should all be included in the TOC Medications section. Ideally, Medications should be linked to the problem for which they are indicated. Within the US Core Procedure, several diagnoses are listed — Delirium, Depression, and Psychosis — and should not be included.
Section Code: LOINC 82593-5 Immunization summary report
Description: List of immunizations an individual has received and when. May also include a schedule for future immunizations.
Usage Notes: No additional guidance beyond the description above.
Section Code: LOINC 69730-0 Instructions
Description: Directions given to an individual designed to teach about prevention, diagnosis, monitoring, or treatment of conditions or functional impairments.
Usage Notes: Education/instructions provided at discharge should be included.
