How Electronic Data Capture Improves Data Quality In Clinical Research Studies?

Electronic Data Capture (EDC) is increasingly used across the world as the preferred means of recording clinical trial results. The system evolved from the RDC or Remote Data Capture system of the 1990s. During their time, RDCs were difficult to use. Check out the video below to learn more:

They often required extensive training when using the specialized devices. Today, the wide availability of computers made for a more universally accessible tool.

While some studies still use pen-and-paper recording and analysis, this is not advisable for larger setups. Clinical research is usually rigorous, relying on the timely and exact capture of important data.

After capture, several stages of processing are involved. Manual processes increase your margin for error. Also, both RDCs and pen-and-paper systems do not allow for easy interoperability between different systems and studies. The EDC addresses this concern.

What is the EDC?

The EDC is a type of software, which stores the data collected and processed during clinical trials. It plays an important part in clinical data management. It is important in different parts of the trials, since it provides you a facility for information input.

It also allows for a means to process and report this information easily. EDCs have a lot of advantages over the usual manual operations. These include the following:

Ease of Access - Getting the data is as easy as entering keywords into the system. When configured, EDCs allow for real-time access and monitoring. Upon the completion of trials, an EDCs interface also allows easy access of data for analysis.

Security - EDCs are often credential-based, letting only those with proper access look into the database. This protects the privacy of any person involved in the study.

Encryption measures can also be in place to avoid compromising the clinical trial management system. Unlike pen-and-paper systems, EDCs can also back the data up in remote servers.

Clinical trial software often allows this option for a secure upload to the cloud, without reducing the availability of data. This makes sure no data is lost even if your primary database is corrupted.

Cleanliness of data - Erroneous and irrelevant data may sometimes end up in manual processes due to the different ways individual researchers interpret entry fields.

In an EDC, the input may be restricted only to a specific set of values. This also allows the interface to search through all your records at a moments notice.

Cost - Just like most eClinical solutions, EDCs can range from the expensive, enterprise solutions to the free, open-source projects. The type of EDC installed depends on your requirements, but any expense in this part will be an investment in the efficiency of clinical processes.

Trends in the EDC and in Clinical Data Management

Especially in technologically advanced countries, EDC has been widely adopted across the world. For example, Canada has been using EDCs in more than 41% of its clinical trials. This was just back in 2009.

Most of the studies reported using an EDC are those in larger-scale, industry-related studies.

Flexible setups

In most developing regions, one of the major blockers of EDC adoption is the workflow. Most practitioners are used to working with the pen-and-paper systems they have been using for so long.

In fact, a study found out that more than half of the practitioners consider it improper to enter data into EDCs while still conversing with the patient.

To get past this, newer EDCs are adopting pen-and-paper like devices such as digital pens, tablets, and the like. This allows for a modernized point-of-contact system without compromising workflow.

EDCs can also be connected with other clinical trial management software to ensure a synergized setup. Adverse event reporting tools, supply management software, and similar others can be synced. Data can also be imported from one resource to another.

Standards

Because Electronic Data Capture software are already being widely adopted, standards have also cropped up to regulate their use. Such standards enforce technical controls to ensure your datas integrity.

For example, the Code of Federal Regulations mandate a set of requirements for EDCs under Title 21.

Another trend is the appearance of independent data sharing standards. One of the most prominent is the CDISC. The standard encourages the interoperability of information, spanning different software that handle clinical research data.

The standard promotes a platform-independent and a vendor-neutral environment to allow for better information exchange. If your EDC follows the CDISC standard, clinical trial information can be accessed from a different study -- even if it uses a different system.

Clinical Data Solutions -- Evolving

While the immense potential of EDCs has not yet been fully realized, it is growing close. It is poised to be the Internet of the healthcare world, allowing the fast, accurate and unlimited transfer of information. This data can then be processed at any time.

The results of the processes can be exported, then imported by another study. Such a setup allows researchers to build up from the works of others easily by getting their raw data directly.

This technology has the potential to change the global healthcare scene by inviting more participation and synergy from its many components.

Prevent Aggressive Driving With Gps Tracking Devices.



Even for the best drivers, there is some risk involved in just driving down the freeway during the course of your normal day. There is the chance you may encounter bad weather, poorly maintained roads, and rubber necking drivers in rush hour traffic. The risk can become even greater when adding an aggressive driver into the mix.



How many occasions have you seen reports on the news of an accident where a semi-truck was involved? How many times have drivers been absolutely terrified when encountering and overly aggressive trucker on the freeway? Perhaps you have not heard about this, but in the fleet management business, this is unfortunately not that uncommon. For a business owner that runs a fleet of trucks, the last thing they want to find out is that the driver of one of their vehicles was involved in and caused an accident causing injury or death. One way for fleet owners and managers to prevent this is using GPS tracking technology. While it cannot prevent all instances of something like this happening, it can certainly help.



Business owned vehicles are like endorsements on wheels. Almost any commercial vehicle you see on the road will be covered in the logo of the business, which is great marketing. The trouble is when those vehicles are driven by aggressive drivers who are cutting off other drivers, weaving in and out of traffic, speeding, disregarding the laws of the road and the safety of other drivers.



Even if a driver does not actually cause an accident it is important to remember that they are ambassadors of the business while out on the road. The last thing a business owner would want is for their company to receive a poor reputation due to their drivers not obeying the traffic laws. Fortunately a GPS tracker can identify some of these poor driving habits by giving fleet managers some insight to what their drivers are doing. By using a GPS tracking system fleet managers can get the following info:



1.The speed at which the vehicle is moving and if it is in excess of the posted speed limit. This is very important, especially if a driver is excessively speeding in order to make deliveries on time.



2.Alerts of abrupt or quick braking. While this can occur naturally for any number of reasons, if it is a regular occurrence there is a good chance the driver is being too aggressive.



3.The times at which the vehicle is operating. If a driver takes the vehicle home and is driving all over town after hours then this might be a serious problem.
While a GPS device does not allow owners to know everything their drivers are doing they surely can give them some insight into whether their drivers are speeding and driving in a dangerous manner.
