What is an Experiment?

17.5K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Thomson's e/m Experiment

6.6K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments

16.2K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Crossover Experiments01:16

Crossover Experiments

Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Area of Science:

  • Orthopaedic surgery
  • Medical device surveillance
  • Public health registries

Background:

  • The Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) began data collection in 1999 and nationwide implementation in 2003.
  • An established system for identifying prostheses with a higher than anticipated rate of revision (HTARR) was introduced in 2004.

Purpose of the Study:

  • To enhance the quality of care for patients undergoing joint replacement surgery.
  • To provide specific data beyond published annual reports for stakeholders.
  • To monitor implant performance and patient outcomes.

Main Methods:

  • Utilizing data from the AOANJRR, established in 1999.
  • Implementing a system to identify prostheses with a higher than anticipated rate of revision (HTARR) since 2004.
  • Analyzing trends in hip and knee replacement revisions.

Main Results:

  • The ASR Hip Resurfacing System's higher revision rate was identified in 2007 through the HTARR process.
  • A reduction in revision hip and knee replacement rates has been observed over the Registry's operational period.
  • The integration of Patient Reported Outcome Measures (PROMs) and data linkage is planned for future analysis.

Conclusions:

  • The AOANJRR plays a crucial role in monitoring joint replacement outcomes and improving surgical quality.
  • Proactive identification of implant issues, such as the ASR hip, is facilitated by registry surveillance.
  • Future enhancements, including PROMs and data linkage, will allow for more comprehensive analysis of joint replacement surgery effectiveness.
