LONGITUDINAL HEALTH RECORDS

Manifest MedEx provides the expertise public health leaders need to address the social drivers of health (SDOH) that impact 80% of wellbeing. We support counties in two vital ways: powering disease surveillance and population health for public health agencies, and facilitating the cross-sector coordination required for whole person care.

Effective population health management requires collaboration across all levels of care, supported by comprehensive data to identify trends, inform decisions, and enable timely interventions.

Advancing CalAIM and Public Health

Utilize social care data and tools through our MX Engage to coordinate the life-changing services that foster stability and health for those you serve.

Use MX Access to instantly view the health history of individuals who may not have their own records or don’t have a full picture of their health journey.

Use automated notifications (MX Notify) to intervene with testing, education, and outreach in moments that matter.

Get Limited Data Sets collected in near real-time for eight health domains across a geography to generate dashboards and analytics. 

Access the most up-to-date contact information to locate and support those who’ve been lost to follow up.

Manifest MedEx supports counties in two key ways: powering disease surveillance and population health with public health agencies and facilitating the cross-sector coordination needed for whole person care. This includes real-time hospital event notifications, access to longitudinal health records, and social drivers of health (SDOH) data to help address the social factors that impact well-being.

Manifest MedEx’s real-time admission, discharge, and transfer (ADT) notifications, delivered through MX Notify, help counties prevent missed opportunities for communicable disease prevention, enable early intervention and treatment, and enhance case investigation and contact tracing (CICT), especially for populations that are difficult to follow up with.

Yes, at two levels. Some SDOH information, such as Z-codes and referral information documented as part of a person’s care, is already captured within clinical records flowing through MX’s core HIE and is available to users with appropriate clinical access permissions, such as those at clinics. For a broader range of social care data, including care assessments and closed-loop referral tools, counties can participate in MX Engage, Manifest MedEx’s dedicated Social Health Information Exchange (SHIE), giving permitted care teams the consent-based social services data and tools they need to support whole person care and connect residents with needed services.

MX Access is Manifest MedEx’s web-based portal that gives county public health teams instant access to longitudinal health records, including for individuals who may not have their own complete records or full picture of their health history. This supports population health management, case management, and coordination for vulnerable populations.

Yes. Access to data shared within the MX network is tailored to the type of user and their purpose. Public health nurses and other staff involved in providing treatment to patients view identifiable, patient-level longitudinal records through MX Access under clinical-use credentials. Community health workers involved in programs such as home visitation use a dedicated case-file viewer with its own access credentials. Epidemiologists, researchers, and analysts typically use aggregate or deidentified data, such as County Population Health Reports, to understand health trends at a population level rather than the individual level. This tiered approach ensures each user only accesses the level of information appropriate to their role.

Yes. Manifest MedEx offers a series of County Population Health Reports covering key domains such as behavioral health, chronic conditions, immunizations, preventative care, sexual health, social drivers of health, and substance use disorders. These reports, available by zip code and census tract, help counties track resident health and support population stratification alongside their existing public health tools.

Manifest MedEx helps counties better manage the health of CalAIM Populations of Focus through several tools. ADT notifications can be configured by populations, so care teams can target outreach where it’s needed most. Population health reporting and data services help identify gaps in care and opportunities for early intervention. ECM eligibility information available in MX’s longitudinal health records helps providers and care teams learn whether an individual is eligible for Enhanced Care Management, and if so, connect and coordinate care, while clinic users with appropriate access can view an individual’s broader health record to inform that care in the moment. Beyond these tools, Manifest MedEx can also design, build, and facilitate holistic health information exchange between Medi-Cal managed care plans (MCPs) and Third-Party Entities under the Memorandum of Understanding (MOU) requirements of DHCS All Plan Letter (APL) 23-029.

Manifest MedEx supports secure and appropriate data exchange between behavioral health providers and broader care teams, helping close long-standing gaps where behavioral health has often been left out of data exchange, so multidisciplinary care teams have a clearer, more timely understanding of the people in their care.

Manifest MedEx has a bi-directional ADT exchange with the California Mental Health Services Authority (CalMHSA), connecting behavioral health data with the broader MX network. The integration enables real-time ADT messages to flow in both directions: MX sends ADT messages to CalMHSA for individuals with an established relationship with a shared DxF participant, and CalMHSA sends MX inpatient ADT messages for individuals it serves who are also known to MX through a DxF organization. The exchange uses a FHIR API-based matching workflow to ensure notifications are routed accurately and appropriately. This collaboration expands MX’s ability to support care coordination for those receiving behavioral health services, an important capability as California continues to advance integrated care.

Yes, the MX health data network has been part of supporting successful public health initiatives. For example, a real-time notification program supporting congenital syphilis case management in San Bernardino County saved case managers significant time per case and was associated with an 18% decrease in congenital syphilis cases. This model was later expanded to San Joaquin County.
