Yes, MDLinx panel members are used exclusively for online market research.
Physicians/healthcare professionals are the most difficult group to reach online and even more difficult are the specialists. This is an area where MDLinx excels and focuses its recruitment efforts. All recruited physicians are verified prior to starting an online market research study. Our primary sources are via our proprietary 24 Professional healthcare specialty portals.
Members are given free subscriptions to online journal article newsletters related to their specialty and subspecialty. Members are processed through verification and are then invited to participate in market research opportunities for honoraria (monetary incentives) based on the length of interview and area of expertise.
PANEL RECRUITMENT
-
MDLinx evaluates the email addresses of its panel members daily. We have a 7% attrition rate per year due to bad email addresses and opt-outs, which are removed in real time to ensure the best feasibility predictions.
-
Opt-in to market research is primarily through email newsletter. After becoming a member and opting in for newsletters, new members are verified then sent a confirmation of membership. Only then are verified physicians given opportunity to participate in Market Research.
-
MDLinx uses a three step verification process before, during, and after a market research study. Initially we use the DEA, NPI, or Medical Education number to review a physician's registration information. In Japan we use the DCF number as approved by their government. We have identified and verified 96% of the physicians on our panel. Only verified physicians are invited with a unique encrypted key to participate that excludes duplicates in the panel. The respondent provides information for the honoraria once thay have completed the survey. The information from initial verification and final confirmation must match perfectly otherwise the staff receives a fraud alert. All clients are informed if fraudulent responders are found and they are replaced at no cost to the client. Our current fraud rate is .12% or 1 in 800 respondents. All projects go through Quality Assurance and the physician sample is certified.
At the close of each survey campaign, several cross checks (email address, name, mailing address, length of interview participation time) are verified. Those respondents who are evaluated to be fraudulent are removed from the database with a strict one strike policy.

PANEL AND SAMPLE MANAGEMENT
-
Sample is pulled based upon the parameters in the clients insertion order (specialty, subspecialty, geography, etc…). During survey launch, the MDLinx Invite system allows the Project Manager to access any part of the sample population and send invitations to each targeted group either randomly or as required by the project. The MDLinx Invite system has the capacity to perform a "soft" or partial launch in the event that the client would like to see data and make adjustments to the survey based on early results. Future invitations can be issued in batches without duplication.
-
MDLinx panel members are invited to participate through an email invitation (see example):

The default language always includes Length of Interview , honorarium amount, survey link and deadline. Wording is included that there are qualifiers that might lead to disqualification and subsequent termination from the survey. Additional language can be added to the text if special instructions are necessary for more complex surveys. Reminders are also sent to those panel members who have not yet accessed the survey.
-
Participating MDLinx members are awarded only monetary incentives for successfully completing the survey. The incentive varies between two to three dollars per minute based upon specialty and length of survey.
Other conditions exist that may drive up the incentive include a low incidence rate or the urgency to complete a study. Our honoraria are issued by check and are audited prior to distribution. Also, our company's financials are audited every year by an external third party.
-
We have been keeping data on physician behavior and participation for the past 2 years and it allows us to better determine who will participate in a survey. Physicians are limited to one completed survey every 30 days and a maximum of 12 surveys per year to eliminate professional survey takers from the panel. Physicians are are also timed out prior to hitting the federal IRS 1099 tipping point of $600.
-

We will not sell or share this information with outsiders. For comprehensive information about the steps that MDLinx takes to respect this privacy please read our Privacy Policy.
Related to Market Research Studies:

Routine backups are preformed, encrypted, copied to an offsite server farm and written to tape before being transported to a secure offsite location to facilitate disaster recover. All information released needs to be cleared by our Chief Privacy Officer.
-
Quality is a continuum that begins with recruitment/verification, is protected during the survey with our patented system that eliminates duplicates, fraud, and abuse and ends with a certified sample. All clients are informed if fraudulent responders are found and they are replaced at no cost to the client. Our current fraud rate is .12% or 1 in 800 respondents. All projects go through Quality Assurance and the physician sample is certified for all clients.
-
No, we do not.
PARTNERSHIPS AND MULTIPLE PANEL MEMBERSHIP
-
MDLinx uses its own panel exclusively for the studies in the United States or Japan and does not supplement it with sample from other providers. Because we 100% own the sample from these countries we have already de-duped the panel and verified the physicians. Our company only recruits respondents that are members of MDLinx.
We do supplement our non-USA and non-Japan sample via other providers for international studies.
For partnered studies, MDLinx does give advance notification, at the quote stage, to clients when using a third party provider. Third party providers are vetted and are members of ESOMAR and other respected international organizations.
-
MDLinx is the largest panel of specialists in the USA and the largest healthcare panel in Japan. With our 100% ownership we verify and dedup the panel. The limit of no more than 1 completed survey every 30 days eliminates professional survey takers across the board. Ideally MDLinx would be the only provider of physician studies however, we will work with clients to dedup surveys that may be fielded with more than one panel.
DATA QUALITY AND VALIDATION
-
Start rate and participation (or response) rate are metrics that we track for each study and differ according to specialty, as well as the complexity of the study. In order to assure then highest response rate, we can target sample based on sub-specialty to get as close to the correct target group as possible. Dropout rate would be calculated by the company hosting the study.
-
MDLinx collects very detailed behavioral and participation information about an individual then applies panel rules to that information. We also use the participation information to drive predictions of future interest in studies for feasibility. The technology used for this predictability is within our feasibility calculator which is a patented piece of technology.
-
The hosting company that is running the survey and collecting data typically perform the data quality analysis. MDLinx limits our involvement to providing verified physicians and monitoring for duplicates, fraud, and abuse throughout the survey process. We do however perform a validation check at the conclusion of each project, confirming all respondents are verified and acceptable. Addiaiotnaly we work with our clients as project data is reviewed and remove speeders and straight liners. These respondents are removed from the any Market Research participation; we have a one strike policy.
-
MDLinx has a hotline set up for physicians to call with their survey number and get immediate assistance as well as an email address that goes to our dedicated customer service team to assist members.
-
MDLinx provides the number of starts, number of screenouts, number of overquotas, number of completes, average length of interview, and certifies the sample is made up of unique qualified individuals who have been triple verified for the highest quality.
