The Open Path Warehouse is designed to aggregate records from multiple Homeless Management Information System (HMISs). The software can assist a community that has agencies using multiple HMIS systems within a CoC, providing an up-to-date view of individual client situations. It can also be used across a large geographic region, helping to coordinate services and perform analyses.
The system is designed to:
Process client record updates daily from multiple sources
Store information beyond the HUD HMIS specification, including assessments
Support coordinated care efforts, giving service providers a (permissions-managed) view of comprehensive client histories
Identify vulnerable and chronically homeless individuals throughout a community
Generate HUD-required reports
Monitor data quality across multiple agencies
The Open Path HMIS Warehouse supports multiple ways of gathering data, frequently, with minimal labor. HMIS CSV export files are uploaded nightly, and HMIS APIs are called for additional data (including assessments, case manager information, and photos). The platform can be readily customized to access third-party structured data (like calendar appointments and medication lists). A dashboard provides administrators a clear view of the status of all import processes.
Records merging and de-duplication is sophisticated, and is handled in three ways:
Records that are clear matches, sharing a combination of name, birthdate, and SSN, are automatically merged
Records that are probable matches, based on statistically calculated similarity, are presented to an administrator for confirmation
Any two records can be merged (or un-merged) at any time by an administrator
Merge decisions are preserved indefinitely and are not affected by subsequent data loads. No client information is overwritten during a merge. Rather, multiple records are flagged as one for viewing and reporting.
