40% Fewer Readmissions Through Predictive Patient Intelligence
Transforming Preventive Healthcare with AI-Driven Risk Prediction
Client Overview
A regional NHS trust in England partnered with Prakash Software Solutions Pvt. Ltd. to address one of the most persistent challenges in healthcare operations — preventable patient readmissions.
As they handled over 120,000 patient episodes per year, they were constantly faced with patients being readmitted back into the hospital 30 days after their discharge, with many times their condition deteriorating during that time. The clinical teams handling such cases had a lot of patient data available at their disposal, which, unfortunately, was scattered around. The client needed a solution where they would leverage artificial intelligence for developing a predictive tool for determining which patients would possibly be admitted back into the hospital soon, better follow-up planning, and improved continuity of care.

The Challenge
Hospital readmission rate was creating problems in terms of operations, increasing treatment costs, and, above all, affecting patient outcomes.
The discharge system at the trust was very dependent on clinical expertise and manual assessment. Although healthcare experts were very competent, they were working under great time constraints, which made it impossible for them to review each and every factor before discharging a patient. There were many critical factors including past admissions, patient’s history of medication, laboratory reports, risks to social care, and lack of follow-ups.
Some of the major challenges included:
- Fragmented patient data that is dispersed across several healthcare providers
- Discharge process that involves manual procedures with little predictability
- Challenges in recognizing high-risk patients before discharging them
- Inability to provide real-time clinical decision support
- Higher risk of readmission among vulnerable patient populations
- Requirements of full compliance with NHS data governance policies
The solution needed to be something that would function silently in the background, analyzing vast amounts of data from patients automatically, providing clinicians with the necessary information just at the right time when discharge decisions had to be made.
One of the biggest priorities for this project was making the technology useful in real clinical environments. Healthcare professionals already work under significant pressure, so the AI had to support decision-making without adding complexity to their workflow.
Our collaboration with the clinical teams ensured that our predictions would be actionable and trustworthy throughout the development process. The combination of knowledge about the healthcare sector along with predictive analytics enabled us to develop a model that will help care teams intervene early enough for their patients.

How PSSPL Helped
An AI-based platform for predictive patient intelligence was developed which was expected to seamlessly integrate itself into the process of discharging patients from hospitals without interfering with the clinical process.
Both structured and unstructured data available from various hospital systems like electronic health records, pathology records, pharmacy records, and social service records were used in order to determine patient’s risk of being readmitted after being discharged from hospital.
The predictive model was trained using four years of historical admission and readmission data. More than 40 patient variables were analyzed, including diagnosis history, medication changes, lab trends, previous admissions, referral activity, and social vulnerability indicators.
In order to enhance clinician acceptance, the AI insights were incorporated into the existing EPR software. This allowed healthcare professionals to gain access to the information without changing software or platform.

Implementation Journey
Lorem We build an deep learning models for industries aligned with an analysis of their needs. Each solution is built to reduce manual effort, improve customer experience, scale, stay compliant, and integrate seamlessly with existing systems.
Discovery & Clinical Assessment
The NHS stakeholders, clinical teams, and operational managers were engaged in order to study the current discharge procedures, patterns of readmissions, and associated risk factors. The relevant data sets were then explored for meaningful predictors.
AI Model Development
Our data science team created gradient boosting algorithms based on historical admissions and patient outcomes. The capability of generating explanations of AI predictions was added in order to provide transparency.
Workflow Integration
The predictive tool was integrated into the current EPR systems at the trust level by leveraging FHIR APIs and other messaging standards in the field.
Testing & Optimization
Intensive testing and validation were done through patient groups and hospital departments. The AI systems were constantly optimized for a perfect balance between prediction accuracy, model explainability, and usability.
Key Outcomes
40% Reduction in 30-Day Readmissions
The trust achieved a significant reduction of readmissions by high-risk patients within six months of implementation.
83% Predictive Model Precision
The AI system correctly predicted high-risk patients before discharging them from hospital.
Faster Post-Discharge Follow-Up
High-risk patients received GP follow-up and support planning 2.4x faster compared to previous workflows.
Estimated Annual Savings of £1.1M
Avoidance of unnecessary readmissions led to decreased costs and better management of resources.
Improved Clinical Visibility
Access to patient risk information was provided directly within care team workflow.
Transforming Healthcare Decision-Making with AI
This project showed the potential for predictive AI to help healthcare practitioners by identifying risks for patients in advance, aiding in discharge planning, and offering proactive care. This was not about replacing medical judgment; rather, it augmented that judgment by giving the healthcare teams the insight they required to act early and avoid preventable issues.
In time, the same predictive capabilities will be applied to inpatient deterioration detection, frailty identification, and long-term patient engagement initiatives at the NHS trust.
Let’s build healthcare solutions that are intelligent, scalable, and designed around better patient outcomes.
