Pareto Chart00:52

Pareto Chart

7.0K
A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.
The Pareto chart is named after the Italian economist Vilfredo Pareto, who described the Pareto...

Hospitals-I

906
Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Pie Chart01:04

Pie Chart

14.4K
A pie chart (or a pie graph) is a circular graphical chart or a pictorial representation of categorical data. It is divided into slices of pie each indicating numerical proportions. It is also used to show the relative sizes of data in a single chart.
In a pie chart, the central angle, the arc length of each slice, and the area are directly proportional to the quantity or percentage it represents. Some real-world examples that can be depicted using pie charts include marks obtained by students...

Steps in Outbreak Investigation

176
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Issues And Trends In Healthcare Delivery System01:29

Issues And Trends In Healthcare Delivery System

5.8K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Summary

Ohio State University developed a novel Dynamic Survival Analysis (DSA) to predict COVID-19 cases and hospital burden. This method provides accurate epidemic modeling without needing prior population or disease data.

Area of Science:

  • Epidemiology
  • Biostatistics
  • Public Health

Background:

  • The rapid spread of Coronavirus 2019 (COVID-19) in Ohio necessitated advanced epidemic modeling.
  • The Ohio Department of Health (ODH) required accurate predictions for resource allocation and public health interventions.

Approach:

  • A novel Dynamic Survival Analysis (DSA) statistical method was developed for parameter inference, prediction, and uncertainty quantification.
  • A geographic component was integrated to down-project statewide predictions to local hospital catchment areas.
  • The methodology was implemented in Python and made publicly available.

Key Points:

  • DSA models epidemic curves with incomplete data, overcoming limitations of standard methods.
  • The approach does not require prior knowledge of susceptible population size, disease prevalence, or epidemic curve shape.
  • Predictions were generated for COVID-19 case counts and hospital burden in Ohio.

Conclusions:

  • The developed methodology provides a robust framework for epidemic forecasting and hospital burden assessment.
  • This approach supports public health agencies in data-driven decision-making during infectious disease outbreaks.
  • The study successfully demonstrated the application of DSA for real-time COVID-19 response in Ohio.
