Naturalistic Observations

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Hazard Ratio

Hazard Ratio

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 evaluating a...

Observational Studies

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One example of...

Data Collection by Observations

Data Collection by Observations

Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Case Studies

Case Studies

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.

Humanistic Psychology

Humanistic Psychology

Humanistic psychology emerged in the mid-20th century as a response to the deterministic and pessimistic nature of behaviorism and psychoanalysis. While behaviorism focused on observable behaviors influenced by the environment and psychoanalysis delved into unconscious motivations, both theories suggested that human actions lacked free will. In contrast, humanistic psychology offers a perspective that emphasizes the innate potential for goodness and growth within every individual.
This approach...

Area of Science:

Human Factors Engineering
Medical Safety
Surgical Performance Analysis

Background:

Human reliability analysis (HRA) methods are crucial for predicting safety in high-risk industries.
Traditional HRA has evolved to incorporate cognitive factors and human failure event (HFE) dependencies, yet remains probabilistic.
Applying HRA to clinical surgery presents challenges due to the higher incidence of human errors compared to industries like nuclear or aerospace.

Purpose of the Study:

To review the evolution and application of Human Reliability Analysis (HRA) methods.
To introduce and explain the Observational Clinical-HRA (OC-HRA) method for surgical safety.
To highlight OC-HRA's capacity for objective assessment of surgical proficiency and safety.

Main Methods:

Review of existing Human Reliability Analysis (HRA) techniques and their development.
Description of the Observational Clinical-HRA (OC-HRA) methodology.
Prospective data capture and analysis of human failure events (HFEs) in clinical settings.

Main Results:

HRA methods have become less subjective through the inclusion of cognitive factors and dependency levels.
Observational Clinical-HRA (OC-HRA) offers an objective approach to assessing HFEs in surgery, overcoming limitations of traditional HRA.
OC-HRA facilitates prospective study of errors and objective determination of surgeon proficiency.

Conclusions:

OC-HRA provides a valuable, objective tool for evaluating surgical safety and individual surgeon proficiency.
The OC-HRA method is adaptable for assessing safety and proficiency across various clinical activities, including pre- and postoperative periods.
This approach enhances the reliability and objectivity of safety assessments in the high-incidence error environment of clinical surgery.
