# Best Patient Identity Resolution Software - Page 3

Patient identity resolution software—also referred to as healthcare identity resolution, enterprise master patient index (EMPI), or patient identity management software—facilitates the creation of a single, holistic record view of each patient. Hospital or clinic staff and health care administrators can use patient identity resolution software to deduplicate medical records, minimize errors in patient records, and improve clinical processes. The software pulls patient information from electronic health records (EHRs), hospital systems, pharmacies, and other consumer data sources to coordinate patient data across the health care ecosystem. Patient identity resolution software enables care providers to consolidate patient data that had been historically fragmented across differing systems, facilities, and operations.

There are slight differences between patient identity resolution and [provider data management software](https://www.g2.com/categories/provider-data-management-pdm). Though both systems mine databases to ensure accuracy and updated records, while simultaneously mitigating compliance risks, the latter is focused on qualifying providers, not aggregating and verifying patient information. Additionally, some [identity verification software](https://www.g2.com/categories/identity-verification) and [identity resolution software](https://www.g2.com/categories/identity-resolution) vendors do offer a health care-specific solution; however, these solutions must not be customer-facing and they must be able to evaluate and resolve the patient information found health care-related databases to be included in the Patient Identity Resolution category.

To qualify for inclusion in the Patient Identity Resolution category, a product must:

- Mine, evaluate, and identify the attribute information that resides in the databases of health care (and related) organizations
- Leverage machine learning, fuzzy matching, or other rules-based technology to automate the assessing and performing of identity resolution
- Comply with industry regulation like HIPAA

### VOGSY

Lead-to-cash platform for global professional services organizations, combining PSA capabilities with project-based ERP to manage operations and financial performance. VOGSY is a Professional Services Automation (PSA) and project-based ERP platform designed for global professional services organizations that need to manage the full lead-to-cash lifecycle, including sales opportunities, project delivery, resource planning, project accounting, invoicing, and financial performance in a single operational system. The platform helps consulting firms, agencies, technology services companies, and other project-based businesses coordinate work across teams, offices, and countries while maintaining visibility into operational and financial performance. As a PSA and services ERP platform, VOGSY supports the full lead-to-cash lifecycle, allowing organizations to move from opportunity management and project planning to delivery, billing, and revenue reporting. The platform integrates operational data with financial insights, enabling leadership teams to track utilization, forecast revenue, and analyze project profitability across multiple entities and currencies. VOGSY combines the operational capabilities of PSA software with multi-entity project finance and reporting capabilities of a project-based ERP, enabling organizations to manage both delivery and financial performance. VOGSY is commonly used by professional services firms with 50 to 1,000 employees that operate across multiple regions or legal entities. These organizations often face challenges managing global delivery, aligning project execution with financial reporting, and maintaining visibility into margins and capacity across distributed teams. These organizations often require both operational coordination (PSA) and financial structure (ERP), particularly when managing multiple entities, currencies, and reporting requirements. VOGSY provides a centralized PSA platform that connects project operations with financial outcomes while allowing organizations to retain their existing regional accounting systems. Key capabilities: • End-to-end lead-to-cash workflow management connecting CRM opportunities, project planning, delivery, billing, and revenue recognition • Global resource management and capacity planning for allocating talent across projects, regions, and teams • Multi-currency project accounting across ERP entities and consolidated financial reporting • Time tracking, expense management, and automated billing tied directly to project budgets and contract terms • Project profitability analysis and ERP-level financial reporting, utilization tracking, and revenue forecasting • AI assistant provides profitability, capacity, and client health details (or data or reports) in natural language and automates daily tasks Security, compliance, and infrastructure: • ISO 42001 • ISO 27001 • SOC 1 • ISAE 3402 • Hosted on Google Cloud for global scalability and security • SSO support for Microsoft 365 and Google Workspace Integrations: • HubSpot • Salesforce • Zoho • Pipedrive • Copper • QuickBooks • Xero • Sage • Deltek • Certinia • Oracle NetSuite • Exact • Tally • Datev • Microsoft 365 • Google Workspace • Jira • Other web applications • API-based synchronization By connecting project delivery data with financial reporting and operational planning, VOGSY helps professional services organizations streamline global operations through a unified PSA and project-based ERP platform.

VOGSY brings these capabilities together in a single platform, providing a more connected view of operations, resource utilization, and project profitability. Finance, operations, and delivery teams work from a shared source of operational and financial intelligence while maintaining compatibility with existing accounting systems across different countries.
