The COVID-19 surge led to a significant increase in inpatient falls. An automated predictive analytic model showed promise for accurately assessing patient fall risk in resource-limited settings.
Area of Science:
- Healthcare Management
- Patient Safety
- Epidemiology
Background:
- The COVID-19 pandemic necessitated significant changes in hospital operations, including nurse staffing and workflows.
- These changes occurred in resource-constrained environments, potentially impacting patient care delivery.
- Patient falls are a critical safety concern in hospitals, especially during public health crises.
Purpose of the Study:
- To investigate the rate of inpatient falls during the initial COVID-19 surge compared to the pre-surge period.
- To evaluate the performance of an automated predictive analytic algorithm against the established Johns Hopkins Fall Risk Assessment tool.
- To determine the utility of predictive models for fall risk assessment in resource-limited healthcare settings.
Main Methods:
- A retrospective review of patient falls was conducted, comparing a 3-month period before the COVID-19 surge with the first 3 months of the surge.
- Data collected included the total number of falls, overall fall rates per 1000 patient-days, and fall risk assessment scores.
- The accuracy, sensitivity, and specificity of the Johns Hopkins Fall Risk Assessment and an automated predictive analytic model were compared.
Main Results:
- A statistically significant increase in the inpatient fall rate was observed during the first 3 months of the COVID-19 surge (2.48/1000 patient-days) compared to the preceding 3 months (1.89/1000 patient-days; P = .041).
- The Johns Hopkins instrument demonstrated higher sensitivity (78.9%) than the predictive analytic model (57.0%).
- However, the automated predictive analytic model exhibited superior specificity (71.3%) and accuracy (71.2%) compared to the Johns Hopkins instrument (54.1% and 54.3%, respectively).
Conclusions:
- The COVID-19 surge was associated with a higher rate of inpatient falls, highlighting a critical patient safety issue.
- While the Johns Hopkins Fall Risk Assessment had higher sensitivity, the automated predictive analytic model offered better specificity and overall accuracy.
- The findings suggest that automated predictive analytic models can be effectively utilized for accurate patient fall risk classification, particularly in resource-constrained environments.

Residuals and Least-Squares Property
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
