Clinical evidence & health system impact

Evidence for post-discharge monitoring

The clinical rationale for structured post-discharge monitoring is well-established in the literature:

• Readmission rates: 5–15% of patients are readmitted within 30 days across most surgical and medical cohorts
• Preventability: Retrospective analyses consistently estimate 30–50% of readmissions are potentially preventable
• Timing: Most preventable readmissions occur in the first 7–14 days post-discharge, when monitoring is most valuable
• Intervention points: Early identification of deterioration allows management through outpatient review, community care, or telephone advice—avoiding emergency presentation

Projected health system impact

Conservative modeling based on published literature suggests the following impact at a typical large hospital:

Economic value

The recovered bed capacity translates to significant operational value:

• Direct cost avoidance: Each avoided readmission saves the direct cost of the admission episode
• Throughput improvement: Freed bed-days can be reutilized at approximately 70% efficiency
• Combined value: $8.1M+ in projected annual operational value for a single high-volume surgical unit

These projections are conservative estimates based on published literature. Actual outcomes will be measured through structured clinical evaluation.

Our approach to evaluation

Aescia engages with health services through scoped, time-limited clinical evaluations with:

• Predefined endpoints and success criteria
• Transparent outcome reporting
• Site-specific ethics and governance approvals
• Comparison against matched historical cohorts where appropriate

We do not seek routine clinical deployment without appropriate evidence. Our commercial model is aligned with demonstrated outcomes.

Regulatory posture

Aescia is positioned as Software as a Medical Device (SaMD):

• Current use is limited to approved evaluation contexts
• Development follows IEC 62304 software lifecycle practices
• Risk classification and regulatory pathway completion is in progress
• All clinical outputs are advisory and require clinician review
