Insights
A new Patient Information Based Algorithm (PIBA) estimates COVID-19 death rates in real-time using daily case data. This method analyzes patient information patterns to provide accurate, dynamic mortality rate calculations.
Area of Science:
- Epidemiology
- Public Health
- Data Science
Background:
- The COVID-19 pandemic necessitated accurate real-time monitoring of disease spread and mortality.
- Estimating the true death rate of emerging infectious diseases like COVID-19 presents significant challenges due to data lags and reporting variations.
Purpose of the Study:
- To introduce and validate a novel algorithm, the Patient Information Based Algorithm (PIBA), for real-time estimation of COVID-19 death rates.
- To apply PIBA using early outbreak data from China and South Korea to assess its effectiveness.
Main Methods:
- Collected daily COVID-19 confirmed cases and death data from official sources in China and South Korea.
- Adapted the Patient Information Based Algorithm (PIBA), assuming patient-to-death durations follow a normal distribution.
- Calculated real-time death rates by weighting individual rates based on lagging days and their probabilities, validated against current case fatality ratios.
Main Results:
- The PIBA methodology was illustrated with six tables using data from China and South Korea.
- The study presented a figure showing estimated infection rates, serious patient conditions, and retrospective estimation of COVID-19's initial occurrence.
- The PIBA method demonstrated a viable approach for estimating dynamic COVID-19 death rates.
Conclusions:
- The Patient Information Based Algorithm (PIBA) provides a robust method for real-time COVID-19 death rate estimation.
- PIBA's adaptability to early outbreak data from China and South Korea highlights its potential utility in public health surveillance.
- Further application of PIBA can aid in understanding disease dynamics and informing public health interventions.
Abstract:
The data of COVID-19 disease in China and then in South Korea were collected daily from several different official websites. The collected data included 33 death cases in Wuhan city of Hubei province during early outbreak as well as confirmed cases and death toll in some specific regions, which were chosen as representatives from the perspective of the coronavirus outbreak in China. Data were copied and pasted onto Excel spreadsheets to perform data analysis. A new methodology, Patient Information Based Algorithm (PIBA) [1], has been adapted to process the data and used to estimate the death rate of COVID-19 in real-time. Assumption is that the number of days from inpatients to death fall into a pattern of normal distribution and the scores in normal distribution can be obtained by observing 33 death cases and analysing the data [2]. We selected 5 scores in normal distribution of these durations as lagging days, which will be used in the following estimation of death rate. We calculated each death rate on accumulative confirmed cases with each lagging day from the current data and then weighted every death rate with its corresponding possibility to obtain the total death rate on each day. While the trendline of these death rate curves meet the curve of current ratio between accumulative death cases and confirmed cases at some points in the near future, we considered that these intersections are within the range of real death rates. Six tables were presented to illustrate the PIBA method using data from China and South Korea. One figure on estimated rate of infection and patients in serious condition and retrospective estimation of initially occurring time of CORID-19 based on PIBA.
