Contingency Table01:29

Contingency Table

3.9K
A contingency table provides a way of portraying data that can facilitate calculating probabilities. It is a method of displaying a frequency distribution as a table with rows and columns to show how two variables may be dependent (contingent) upon each other; The table helps determine conditional probabilities quite quickly and can help systematically organize, analyze and quantify data. The table displays sample values concerning two variables that may be dependent or contingent on one...

Determination of Expected Frequency01:08

Determination of Expected Frequency

1.7K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

Hazard Ratio

752
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

Survival Tree01:19

Survival Tree

498
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Introduction to Test of Independence01:21

Introduction to Test of Independence

2.1K
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

Hazard Rate01:11

Hazard Rate

525
The hazard rate, also known as the hazard function or failure rate, is a statistical measure used to describe the instantaneous rate at which an event occurs, given that the event has not yet happened. From a probabilistic perspective, it represents the likelihood that a subject will experience the event in a very small time interval, conditional on surviving up to the beginning of that interval. In terms of frequency, the hazard rate can be viewed as the ratio of the number of events to the...

  • Healthcare research
  • Clinical informatics
  • Patient safety

Background:

  • Hospital-acquired bed falls are a significant concern in patient safety.
  • Understanding the complex interplay of contributing factors is crucial for effective prevention.

Purpose of the Study:

  • To analyze the conditional dependency structure of factors contributing to inpatient bed falls.
  • To identify stable configurations of these factors using Bayesian network analysis.

Main Methods:

  • Retrospective analysis of 102 inpatient bed-fall incident reports.
  • Bayesian network structure learning using a hill-climbing algorithm.
  • Structural stability assessed via non-parametric bootstrap resampling.

Main Results:

  • Identified stable directed edges in the Bayesian network.
  • Sudden consciousness changes linked to hypotension and safety measures.
  • Nighttime sedative use associated with toileting and unassisted exits.

Conclusions:

  • Bed falls result from interactions among a limited number of recurrent factor configurations.
  • Bayesian network analysis is valuable for identifying patterns and informing fall prevention.
  • Findings support scenario-based strategies in clinical nursing practice.
