The CMS Acute Hospital Care at Home programme established that hospital-level care can be delivered in a patient's home without sacrificing clinical quality — and that CMS will reimburse it at inpatient rates when specific programme requirements are met. The technology stack required to qualify for and sustain programme approval is substantially more demanding than a standard telehealth deployment.
Health systems that have attempted Hospital at Home programmes with standard telehealth infrastructure quickly discover the gap. The CMS requirements for patient monitoring frequency, clinical response times, and escalation protocols are specific, measurable, and audited. Technology that cannot produce the documentation trail required to demonstrate compliance with each requirement creates both CMS compliance risk and clinical safety risk.
CMS Programme Requirements: What Technology Must Demonstrate
CMS Hospital at Home waiver requirements specify that participating health systems must conduct nurse visits (in-person or remote) at minimum twice daily, provide on-demand audio and video capability for clinician communication, and dispatch in-person clinical resources within 30 minutes in emergency situations. Each of these requirements must be documented per patient per day in a format that survives CMS programme review.
The twice-daily monitoring requirement can be satisfied through a combination of automated vital sign monitoring and nurse telehealth visits, but the documentation must show the timing, clinical assessment performed, and nurse identity for each monitoring event. Automated monitoring alone does not satisfy the nurse visit requirement. The technology platform must support structured nursing assessment documentation with timestamp capture, not free-text visit notes.
The 30-minute in-person response requirement is a logistics and dispatch capability, not just a technology capability. However, the technology platform must integrate with the health system's dispatch mechanism and generate a timestamp record of dispatch initiation and on-scene arrival for every activation.
Remote Monitoring Device Requirements for Hospital-Level Care
Hospital at Home programmes require continuous or near-continuous vital sign monitoring. The device set typically includes continuous pulse oximetry, intermittent blood pressure monitoring, and cardiac rhythm monitoring. These are FDA-regulated Class II devices. Consumer-grade wearables do not satisfy clinical-grade monitoring requirements and create both patient safety risk and CMS compliance risk if used as the primary monitoring modality.
Clinical-grade RPM devices must transmit data to a clinical monitoring centre with defined alert response protocols. The monitoring centre must have defined escalation protocols for each alert type and must document alert response times. This documentation becomes part of the CMS programme compliance record.
EHR Integration: Hospital-Level Documentation in a Home Setting
Hospital at Home patients must be documented as inpatients in the health system's EHR. Admission, daily assessments, medication administration, nursing notes, and discharge documentation must follow inpatient clinical documentation standards — not ambulatory or telehealth standards. This creates an EHR integration requirement that most clinical informatics teams have not previously encountered: generating inpatient documentation workflows that operate when the care team and the patient are in different physical locations.
Medication management in the home setting requires a closed-loop medication administration process. Medications are dispensed by pharmacy and delivered to the patient's home; nurses document administration remotely after patient self-administration. The EHR medication administration record must support remote-administration documentation with nurse attestation, satisfying the health system's medication error reporting requirements.
Clinical Decision Support Alerts in the Home Monitoring Context
Alert thresholds designed for monitored inpatient units are not appropriate for Hospital at Home. An inpatient cardiac monitor alert that triggers nursing assessment within 2 minutes requires a different response in a home setting where the nearest nurse may be 20 minutes away. Alert logic must be tuned for the home monitoring context — with earlier warning thresholds and patient-facing notifications for conditions where patient self-management is appropriate.
The CDS configuration for Hospital at Home requires clinical governance. Physician and nursing leadership must define alert thresholds, escalation protocols, and patient self-management criteria for each monitored parameter. This governance work is a prerequisite for safe technology deployment, not an afterthought.
The Algorithm Approach: Hospital at Home Technology Architecture
The Algorithm designs Hospital at Home technology stacks that treat CMS programme requirements as engineering specifications. We map each CMS documentation requirement to a specific platform capability, identify gaps between current telehealth and RPM infrastructure and programme compliance requirements, and design the integration architecture that closes those gaps. Our clinical informatics team defines the CDS alert logic and escalation protocols safe for home monitoring contexts. The result is a technology architecture that generates compliant programme documentation automatically rather than depending on manual documentation by care coordinators.
