Statistical analysis turns operational hospital data into actionable decisions. This case study presents calculations and KPIs you can implement today — from patient wait-time percentiles to ARIMA forecasting for inventory. Use the interactive sections to copy snippets for implementation.
Patient wait time is one of the most visible metrics for patients. Calculate mean, median and percentiles (P75, P90, P95). Use time-series decomposition to identify weekly daily patterns and queueing models to design service capacity.
Track Bed Occupancy Rate (occupied beds / total beds). Use ALOS and arrival distributions to forecast bed demand. Apply scenario analysis for seasonal surges (e.g. dengue, influenza).
| Metric | Value | Action |
|---|---|---|
| Bed Occupancy Rate | 78% | Monitor weekly; open surge beds at 90% |
| Average Length of Stay | 4.6 days | Discharge planning to reduce ALOS |
| Turnover Interval | 2.4 hours | Improve cleaning throughput |
Use logistic regression or gradient boosting models to compute readmission risk. Feature examples: comorbidities, medication adherence, LOS, discharge destination.
Deploy: risk score > threshold → schedule tele-follow-ups; med adherence program.
Match staffing to predicted patient arrivals using regression or queuing simulation. Key outputs: predicted required nurses per shift, overtime forecasts, burnout risk index.
Track moving averages of infection incidence per ward; use control charts to detect out-of-control signals. Spatial heatmaps help detect clustering.
Forecast drug demand with ARIMA/Holt-Winters. Implement ABC/VED classification to prioritize stock. Alerts for reorder point based on lead time and safety stock.
| KPI | Formula | Target |
|---|---|---|
| Avg Wait | mean(wait_minutes) | < 30 mins |
| P95 Wait | percentile(wait_minutes,95) | < 90 mins |
| Bed Occupancy | occupied / total | 75%-85% |
| 30d Readmission | count(readmit within 30d)/discharges | < 10% |
