OASIS E1: A Step Toward Improved Patient Outcomes

The 2025 release of OASIS E1 marks an update to the previous OASIS E, incorporating changes that reflect ongoing improvements in healthcare delivery and the increased focus on a comprehensive view of patient health. These changes aim to enhance the accuracy of assessments, streamline the documentation process, and improve overall reporting.

With the shift to OASIS E1, home health agencies will need to adjust how they collect, document, and use patient data. This article will provide an in-depth look at the differences between OASIS E and OASIS E1, focusing on how these changes will impact documentation practices, reimbursement, and patient outcomes. Agencies will learn how to adapt to the new system and ensure they remain compliant while optimizing the quality of care provided.

The Shift Toward Holistic Patient Assessments

One of the primary changes introduced by OASIS E1 is its broader scope in assessing patient characteristics. While previous versions of the OASIS primarily focused on a patient’s clinical condition, OASIS E1 takes a more holistic approach, requiring home health agencies to document not only medical conditions but also functional, cognitive, and social aspects of a patient’s health. This comprehensive approach provides a more complete picture of a patient’s overall well-being, enabling providers to create more tailored and effective care plans.

Comprehensive Documentation of Functional Status

Functional status has always been a key component of the OASIS assessment, as it helps determine the level of care a patient requires. However, OASIS E1 introduces more detailed documentation requirements for functional status, allowing providers to better assess a patient’s ability to perform various activities of daily living (ADLs) and instrumental activities of daily living (IADLs). For instance, in addition to basic tasks like bathing, dressing, and feeding, OASIS E1 asks providers to document a patient’s ability to manage more complex activities such as handling finances, preparing meals, or managing medications.

By capturing a more nuanced view of a patient’s functional status, OASIS E1 enables home health agencies to develop more personalized care plans. For example, if a patient is able to complete some activities independently but requires assistance with others, the care plan can be adjusted to address these specific needs. This individualized approach not only enhances the patient experience but also contributes to better outcomes, as patients are more likely to engage with care that is tailored to their specific abilities and challenges.

Social Determinants of Health (SDOH)

The inclusion of social determinants of health (SDOH) in OASIS E1 is one of the most impactful changes for home health providers. SDOH refer to the social, economic, and environmental factors that influence health outcomes, such as access to healthcare, housing stability, transportation, and food security. While these factors have long been known to affect health, they have not always been adequately documented in home health assessments.

OASIS E1 now requires home health providers to assess and document SDOH, offering a more holistic view of a patient’s health. For instance, if a patient lives in an area with limited access to grocery stores or transportation, this may affect their ability to manage chronic conditions, take medications as prescribed, or attend follow-up appointments.

Cognitive and Mental Health Function

Another significant update in OASIS E1 is the enhanced focus on cognitive and mental health function in home health patients. Previously, cognitive function was only assessed to a limited degree, but OASIS E1 now requires more detailed documentation of a patient’s memory, orientation, and ability to perform tasks. This change acknowledges that cognitive impairments, such as dementia or delirium, can have a profound impact on a patient’s ability to follow care plans, manage medications, and engage in rehabilitation.

Documenting cognitive and mental health function helps home health agencies better understand the challenges patients may face in managing their health. If a patient shows signs of cognitive decline, the care plan can be adjusted to include strategies for promoting safety, memory aids, and caregiver support. Additionally, this more detailed documentation allows for better coordination with other healthcare providers, such as physicians or neurologists, to ensure that the patient receives the appropriate interventions. 

Improved Accuracy in Outcome Measurement

One of the key objectives of OASIS E1 is to improve the accuracy of outcome measurement. Accurate outcome measurements are essential for evaluating the effectiveness of home health services, ensuring quality care, and determining reimbursement rates. With the enhanced documentation requirements introduced by OASIS E1, home health providers can capture a more precise picture of a patient’s needs, abilities, and health status, which in turn leads to more accurate outcome measurements.

Better Tracking of Functional Outcomes

With the more detailed documentation of functional status, OASIS E1 enables home health agencies to track a patient’s progress in managing daily activities more effectively. For example, if a patient initially requires full assistance with bathing and dressing but, over the course of treatment, becomes more independent in these activities, the improvement can be documented and tracked.

This more accurate tracking of functional outcomes allows home health agencies to demonstrate the effectiveness of their services and showcase the improvements patients have made under their care. It also provides valuable data for quality assurance and performance improvement efforts, as agencies can identify areas where patients may require additional support or where certain interventions have led to significant improvements.

Enhancing Communication and Coordination of Care

The updates introduced by OASIS E1 also have the potential to improve communication and coordination among healthcare providers. With the expanded documentation of cognitive function, social factors, and functional status, home health agencies are better equipped to share relevant information with physicians, specialists, and other members of the care team. This improved communication ensures that all providers are on the same page when it comes to a patient’s care plan and health status, ultimately leading to better patient outcomes.

Home health software can play a key role in enhancing communication and coordination. Integrated homecare software systems allow for the seamless exchange of patient data across providers, ensuring that all team members have access to the most up-to-date information. This reduces the risk of errors or missed information and enables the care team to make more informed decisions about patient care.

Adapting to OASIS E1 for Improved Patient Outcomes

Adapting to the changes introduced by OASIS E1 is essential for home health agencies to maximize the benefits of the new assessment requirements. Agencies must ensure that their staff is well-trained and equipped to handle the more detailed documentation requirements, and that they have systems in place to track and manage the expanded data collection.

Staff Training and Education

Staff education is a key component of successful adaptation to OASIS E1. Home health agencies provide training for staff on the new documentation requirements, including how to assess and document functional status, cognitive function, social determinants of health, and medication management. Regular training sessions and refreshers are essential to ensure that all team members are up to date with the changes and can accurately complete the OASIS E1 assessments.

Leveraging Homecare Software for Efficiency and Accuracy

Homecare software can be a valuable tool in streamlining the documentation process and ensuring accuracy in OASIS E1 assessments. Software that is integrated with OASIS E1 can help automate certain aspects of the documentation process, flag potential errors, and ensure that all required fields are completed. This reduces the risk of missed information or incorrect documentation, which can impact patient care and reimbursement.

It can also help agencies track patient progress over time, enabling them to identify trends and make adjustments to care plans as needed. 

Conclusion

The introduction of OASIS E1 marks a significant advancement in patient-centered care for home health agencies. Home health providers can now create more tailored care plans, track patient progress more effectively, and foster improved communication within care teams.

These changes enhance the precision of outcome tracking, allowing agencies to better evaluate the impact of both medical and non-medical influences on patient health. OASIS E1 signifies a forward-thinking shift toward a holistic approach to patient care in the home health sector.
