LeanTaaS

Prediction drives the core modules. iQueue predicts which operating room block time will go unused, surgical demand, infusion peaks and inpatient surges from a hospital's EHR data, and turns those predictions into earlier block releases, chair schedules and discharge priorities; generative AI and workflow assistants handle patient outreach and routine staff tasks.

Around the models sit workflow tools that stand on their own, such as the Exchange marketplace where surgeons release and book open OR time, utilization dashboards, staff rosters, and the implementation and change management team sold as a service.

People act on the predictions. iQueue flags block time likely to go unused and matches open time with surgeons, but release and booking happen in the Exchange, where surgeons and their offices release or claim time themselves, and schedulers use the infusion and bed forecasts to plan. Most EHR workflows are read only; the one write, Push to Epic, sends staff assignments to Epic's Snapboard. Generative AI and automation also take repetitive tasks off staff, such as patient outreach before surgery.

Which of those automated tasks run without a person approving them is not stated.

iQueue is built on predictive and prescriptive analytics: machine learning over a small amount of EHR data, patented optimization that combines lean principles with simulation, and generative AI for staff conversations and workflow assistants. The founders have published a book on the mathematics behind capacity management.

Model types, training data, forecast accuracy and the generative AI's underlying model are not published.

The predictive models are LeanTaaS's own, run in its iQueue service on Amazon Web Services in Virginia and Oregon. A public subprocessor list names nine parties: AWS for hosting, CrowdStrike for security, Datadog for monitoring, Fastly for the web application firewall, Fortra for an SFTP gateway hosted in LeanTaaS's own AWS environment, Mailgun and Postmark for email, Tableau for analytics and Twilio for messaging.

The model provider behind its generative AI features is not named.

Case studies give sites, timelines and results. Children's Nebraska began implementation in September 2021, took one module live system wide in February 2022 and reports a 12 percent increase in surgical volume; OHSU went live in October 2018; Vanderbilt-Ingram Cancer Center reports patient wait times down 30 percent across 126 infusion chairs; Rush's daily completed appointments rose 26 percent and UCHealth's opportunity days fell 8 percent. Across customers the operating room product cites a 5 percent increase in case volume, 40 percent fewer cancellations and 25 percent higher staffed room utilization.

The studies are company reported, with baselines described loosely and no independent evaluation.

LeanTaaS processes patient data for hospitals under its customer agreements, and its privacy policy covers only website visitors and customers' user accounts. The trust center lists data retention and data classification procedures and data encryption among its controls. The schedule and census data iQueue reads identifies who is having which procedure or chemotherapy session.

What the models keep from that data, and whether one hospital's data trains models used for others, is not stated.

LeanTaaS processes personal information on behalf of and at the direction of its hospital customers under its agreements with them, and keeps that information outside its website privacy policy. Its trust center lists HIPAA among its compliance frameworks, alongside SOC 2, HITRUST, TX-RAMP and CCPA.

No business associate agreement or statement of business associate status is public.

LeanTaaS runs a trust center that lists SOC 2, HITRUST, HIPAA, TX-RAMP and CCPA, with a 2026 SOC 2 Type 2 report and a HITRUST r2 certification letter among its resources. Its controls include unique authentication for production databases, accounts and network systems, data encryption, vulnerability and system monitoring, continuity and disaster recovery plans, employee background checks and cybersecurity insurance. LeanTaaS also posts security updates there, such as its September 2025 statement that it was not affected by the Salesloft Drift incident.

The reports sit behind an access request.

iQueue forecasts and allocates operating room time, infusion chairs and beds and supports discharge, staffing and pre op workflows. It does not diagnose or recommend treatment for an individual patient, and its workflow assistants for outreach and readiness review handle scheduling and documentation tasks rather than clinical judgment.

LeanTaaS makes no regulatory claim for iQueue and holds no FDA device listing.

iQueue's models learn from a hospital's own history of block ownership, case lengths, chair use and census to forecast demand and recommend how operating room time, infusion chairs and beds are allocated, and those recommendations feed the Exchange and daily rosters. Allocation built on that history can carry forward whatever pattern of access it holds.

No forecast monitoring, drift review or check on fairness of access across services, surgeons or patient groups is described.

Predictions are reviewed before anything changes. A predicted block release does not happen until a surgeon or scheduler acts in the Exchange, and the Analyze module shows utilization data that stakeholders can check against their own records, so a wrong forecast can be seen and set aside before it moves a case.

No forecast accuracy, warranty, service level or remediation commitment is published.

iQueue connects to Epic, Cerner and other major EHRs through lightweight data feeds, and most workflows are read only. The one write, Push to Epic in Daily Roster, sends staff assignments to Epic's Snapboard. Hospital IQ brought partnerships with Oracle Cerner, Altera Digital Health and Siemens Healthineers, and file transfers run through an SFTP gateway LeanTaaS hosts in its own AWS environment.

No interface specification or marketplace listing is published.

iQueue runs as cloud software as a service on Amazon Web Services in Virginia and Oregon, reached from any computer or mobile device and fed by data from the hospital's EHR. The SFTP gateway for file transfers runs inside LeanTaaS's own AWS virtual private cloud, and Fastly provides the web application firewall for iQueue services.

Tenant isolation and retention periods are not stated.

The value case is set per asset: LeanTaaS puts the return at an additional $100,000 per operating room per year, $20,000 per infusion chair and $10,000 per inpatient bed, and the operating room product cites a return of five to seven times. Product lines are organized around those assets, and a dedicated engagement team implements the software and drives change management under the Transformation as a Service offering.

No price, unit of charge or contract term is published.

iQueue covers three hospital assets and, through acquisitions, the transitions around them: operating rooms (block management, open time, pre op readiness, staffing), infusion centers (chair scheduling) and inpatient flow (surge prediction, discharge prioritization). Hospital IQ added inpatient and surgical workforce management in 2023, and Aidin added post acute placement and referrals in September 2026.

The operating room product runs in more than 550 hospitals across more than 100 health systems. Named case studies include Children's Nebraska, OHSU and Baptist Health for operating rooms and Vanderbilt-Ingram Cancer Center and Rush for infusion.
