Our team is comprised of experts in healthcare, business, and technology.

We continue to improve patient outcomes, increase patient satisfaction, and reduce cost of care through technology.

Highlighted Project

A post-surgical monitoring application tested at Women’s College Hospital showed strong clinical outcomes and cost savings.

Women’s College Hospital was focused on reducing the total length of stay in their hospital while at the same time minimizing readmissions, increasing patient engagement in their own care, and increasing levels of satisfaction. The expedited discharge and at-home patient recovery left them with an absence of outcome data. This had become a barrier to quality improvement.

As such, Women’s College Hospital conducted a research study using a post-surgical monitoring application developed by QoC Health and achieved the following outcomes:


Emerging Complications Detected


Cost Savings


Patient Satisfaction


Reduction in Average Patient Travel
