HSX offers its members and participants a variety of services today to promote health information exchange across the Greater Philadelphia region. During implementation, HSX members and participants work with HSX engagement and adoption staff to ensure services will be deployed in ways that meet organizational needs and promote patient-centered care.
Direct Secure Messaging (Direct)
Provides secure routing of clinical information to providers’ direct addresses using the national Direct Project standards — an email-based protocol for confidential transmission of patient health information between trusted entities. Includes sending of continuity of care (C-CDA) documents with discharge information and referrals for transitions of care.
Provider Directory (PD)
The provider directory contains direct addresses for physicians and other healthcare providers who actively participate with HSX. Members and participants use the directory to send secure messages containing transition-of-care documents to primary care providers and specialists to update them about care their patients have received.
Clinical Activity History (CAH)
Collects recent clinical history about a patient from the patient’s healthcare insurer, based on the patient’s member identification within the health plan and translates this claims/utilization data to a clinical care document — returning this information to the requesting provider or emergency department using Direct secure messaging.
Automated Care Team Finder (ACTF)
Uses the patient’s member identification with his or her healthcare insurer to identify providers involved in the patient’s recent medical care and uses this information to route continuity of care (C-CDA) documents, containing discharge information, to the patient’s identified primary care provider using Direct secure messaging.
Encounter Notification Service (ENS)
Delivers providers and payers who subscribe to the service a notification via Direct secure messaging when one of their patients or members is hospitalized or presents to an emergency department. Subscribing providers and payers can also be notified when their patients or members are discharged from emergency departments or hospitals that participate with HSX.
Clinical Data Repository (CDR)
Collects and retains medical records data about patients, permitting a patient’s provider or care team to query the exchange for clinical information. Large database of health information also becomes a valuable tool for population health tracking, management, and research.
Urgent Patient Activity Liaison Service (uPAL)
The Urgent Patient Activity Liaison service (uPAL) is a patient locator capability. For this resource, HSX uses admission discharge transfer (ADT) data feeds from its member hospitals as a database of locations for patients who have arrived for or completed care at regional hospitals. When HSX member hospitals receive an inquiry seeking information on one or more patients who may have required medical care, they can query HSX for information on where patients may have entered the regional healthcare system in order to find these individuals. May be used in mass crisis scenarios or more routine, individual cases. Assists both families and authorities.
Master Patient Index (MPI)
The master patient index is a database of patients in the HSX service area, against which HSX applies sophisticated matching algorithms to confirm the identity of a patient who comes into care within the regional health system. The MPI supports function of other services such as Clinical Data Repository.
Patient Opt Out Service
As a service to consumers, as well as to provider and insurer members, HSX provides an easy option for patients to request that their clinical information not be shared on the regional exchange. Through the HSX website, consumers or providers can access an online, fax, or mail form permitting patients to remove themselves (opt out) or reinstate themselves (opt back in) to the exchange.
Attendees at The Delaware Valley and New Jersey Health Information Management and Systems Society saw a demonstration of health information exchange between two of the Philadelphia area’s health systems, using a system that will improve everyone’s care in the 21st century.
