Business Challenge
Situation
A leading healthcare organization faced significant challenges in managing its Predictive Census application. Predictive Census is crucial for forecasting the number of patients or beds in a hospital at a future time to optimize resource planning, staff allocation, and scheduling.
However, the existing system struggled with:
Complex and Fragmented Architecture
- The data pipelines contained extensive ETL logic embedded in MongoDB, making maintenance challenging and increasing the risk of errors.
- The reliance on multiple technologies and teams slowed down development and support.
Limited Scalability and Agility
- The current infrastructure lacked flexibility, restricting the ability to scale and adapt to fluctuating healthcare demands.
Operational Inefficiencies
- Heavy dependence on manual processes resulted in high operational overhead and human errors.
- Inadequate monitoring and alerting capabilities hindered proactive issue resolution.
Integration Challenges
- Complex integration with other client systems required significant effort.
- Adapting to evolving client needs and regulatory requirements was difficult.
Why is Predictive Census Important?
Accurate patient census predictions drive efficiency and better healthcare outcomes by enabling:
- Patient safety – Ensuring hospitals have adequate staff and resources.
- Improved health outcomes – Allowing proactive interventions.
- Optimized resource planning – Efficient use of hospital resources and reduced wastage.
- Hospital sizing – Ensuring facilities are neither overcrowded nor underutilized.
⠀
As healthcare demand grows, the organization needed a future-ready solution to enhance accuracy, efficiency, and scalability in Predictive Census forecasting.
Goals
The key objectives were:
- Simplify architecture to improve maintainability and development speed.
- Enhance scalability using cloud-native solutions.
