Advantages Of Edc Systems: How Electronic Data Capture Improves Data Quality In Clinical Research Studies

An electronic data capture, or EDC, system benefits independent medical investigators, as well as clinical research organizations. It provides a great solution for different concerns with clinical data management.

Depending on a particular brand, an electronic capture system is composed of different elements. Regardless of design variations in these electronic systems, the integral components remain. These are a validation tool, a graphical user interface, and a reporting tool. In the field of clinical research, these systems are behind processes that are more efficient. As opposed to data collection in paper form, it is inarguable that electronic data collection is done faster. Beyond convenience, they seem to bring more advantages, too. Learn more about electronic data capture software in the video below:

A Brief Look at Different Kinds of Clinical Research

There are different kinds of clinical research. Electronic capture systems are supportive of each kinds design.

Different kinds of clinical research:

- Diagnostic the practice of looking at alternative ways of identifying medical subjects

- Treatment research also called clinical trial; utilizes a clinical trial management system for data collection with regard to general intervention (e.g. psychotherapy, medication, introduction of new devices)

- Screening the primary aim is to determine the most practical way of identifying medical subjects

- Prevention the primary aim is to determine preventive measures for particular medical subjects

- Genetic studies the primary is for the improvement of a medical subjects predictability with regard to genetics

- Supportive care the exploration of various ways of providing comfort for medical subject; provides discussion about the improvement in the quality of life

- Epidemiological studies the primary aim is to identify causes and patterns in particular medical subjects

The Goal of EDC Systems in Clinical Data Management

An electronic data capture system is a tool that provides support for the collection of data. It also uses automated support for relevant tasks. These tasks include query resolution, coding, supply management, validation, reporting, and randomization.

Electronic capture systems are designed to collect data from different sources. These sources are usually health records, imaging data sources, and laboratory reports.

You can also refer to these data capture systems as clinical trial management software, remote data capture, and eClinical solutions. Since these systems are usually web-based, data is accessible from a device with a web browser. It is also a plus that a thin client is utilized. This means that you can access data with the use of a simple web browser.

The Use of EDC Systems Offers Better Data Access

With an electronic data capture system, data access can be accomplished easily - and more reliably, too. It provides assistance for both simple and complex medical investigations. It is designed to collect in a secure and uncorrupted manner.

As mentioned in the introduction, data collection via electronic capture systems can be done much faster. The concern is not just on the speed of the task, but also rather on its accuracy. So far, the use of electronic systems is commendable since they return accurate data. Since they reduce the time for data input by more than half, they also reduce the total time necessary for the studies completion. Usually, research that would take weeks to finish can be done within 2-3 days with the use of these tools.

These systems allow real-time data access, and they support adaptive clinical trial designs. This is especially beneficial to clinical researchers with ongoing projects; they can take advantage of real-time data for better decision-making.

The Use of EDC Systems Results to Error-Free Clinical Data Solutions

The effectiveness of clinical trial software programs in the enforcement of high quality data is unquestionable. Once programmed, you can utilize them to meet desired goals prior to acceptance in databases.

Clinical software tools are designed to execute error-free processes. They are programmable to follow particular rules. Some of these rules include formatting requirements and ranges.

The Use of EDC Systems Results to Better Rate of Productivity

Better rate of productivity can be expected with an electronic data capture system. As it accelerates productivity, it decreases the cost of research. This is due to the reduction of the number of in-person visits during a clinical process.

These systems are designed to function to enhance productivity. They can resolve minor discrepancies and enable seamless processes.

Consequently, more work is accomplishable.

Granted that the data capture systems are programmed accordingly, instructions for your medical investigation will be followed. There will no longer be a need to facilitate and keep close monitoring during general procedures.

Conclusion: Are the Advantages of EDC Systems Worth Acknowledging?

In conclusion, the adoption of EDC systems is worth considering. They are very effective in lowering costs, without sacrificing the quality of the study. Other than accelerate their progress, these systems are known to improve research project feasibility.

Gps Helps Protect Your Car At Night

When a person parks their automobile in the driveway for the evening they probably don't think much about the possibility of that vehicle being targeted by car thieves. Unfortunately, a vehicle is stolen in the United States approximately every 40 seconds. This means a car owner can become a victim auto-theft literally any minute. So what can those concerned about automotive safety do to safeguard their vehicles from potential thieves at night? The answer is preparation.

Preparation is quite the ambiguous word but when it comes to auto security preparation this can be accomplished by three (3) simple things:

1. Locking The Doors On A Vehicle

2. Parking In Well Lit Areas

3. Utilizing GPS Tracking Technology

Most people know that locking the doors to their vehicle is a smart thing. But everyday people leave their vehicles unattended with the car windows down or with the doors unlocked at night. Hell some people might even leave a spare key inside that vehicle or attached to the outside frame via magnetic casing. So the simplest way to enhance auto security during the evening is to always lock the car doors!

Locking the car doors is a simple task that can prevent automotive theft but sometimes locked doors are a small hurdle for the opportunistic car thief. If a car door is locked but the vehicle is parked in a area that is dimly light or dark, that might be all a car thief needs. In the darkness many car thieves feel safety and with safety comes the potential for them to try and bypass a locked car. The easiest way to prevent this is if a person is planning on parking in the street that they park near a street light or some other area that's well lit. If a vehicle owner leaves their car parked in the driveway overnight they should invest in a motion detection light that will illuminate when movement is sensed. Motion lights can be very helpful in spooking a potential car thief. And for those looking to take their security to the next level they can invest in motion lights that also have hidden camera systems built in them so the moment movement is detected the spy camera will begin recording the property.

Every law enforcement officer or security expert will advise those concerned about automobile safety during the evening to lock their doors and park near a well-lit location. In fact, some people might say this is common knowledge, but what isn't common knowledge is using GPS tracking to boost security. GPS tracking devices can provide vehicle owners real-time updates on where their automobile is moving every 10 seconds! In fact, GPS auto trackers offer a cool feature known as the geo-fence that is essentially a virtual boundary. When the vehicle moves outside of this boundary an alert is sent out to notify the vehicle owner. This means if a car thief bypasses a locked door, doesn't care if the vehicle is parked in well-lit area and gets away inside the stolen automobile, the story isn't over. Although the thief may believe they got away with the perfect crime the reality is a GPS tracker will be sending real-time updates on the movement of that stolen vehicle. This data can be used by police to quickly locate the stolen vehicle and recover it safely.

By diligently remembering to lock car doors, parking in well-lit areas and using GPS car tracking technology, those with automobiles can sleep safe at night knowing their property is safe.
