Mobile Marketing - Connecting With Potential Subjects On the Go

The adoption of mobile devices is advancing at an astounding pace. The overall global mobile advertising market more than doubled in 2013 to almost $18 billion and is set to hit $42 billion by 2017!

According to Pew Research, 52% of smartphone owners have used their phones to look up health or medical information and 19% have downloaded an app specifically to track or manage their health.  People have made these devices an integral part of their lives and they utilize them for everything from communication to entertainment to navigation to retail and most importantly to search for information.

The following provides an overview of the major players in the market.

This exciting media channel presents many opportunities to attract and engage potential patients and can play an important role in your patient recruitment plan.

Let’s look at how your potential subjects are spending their time on their mobile devices at any given time. A patient suffering from migraines residing in Los Angeles is performing a Google search on “best treatments for migraines” from her iPhone. A recently diagnosed Crohn’s patient in Boston just hopped on mayoclinic.org to educate himself about his disease from his HTC One Android phone. A senior in White Plains, NY just joined an online support community for depression from her Surface tablet. A type 2 diabetic living in West Palm Beach just logged into his Glucose Buddy app to help him manage his glucose levels from his Samsung Galaxy. A cancer patient in DesMoines just liked a Thyroid Cancer Awareness community page on Facebook from his BlackBerry. A mother in Dallas just viewed an animated YouTube video about asthma with her child from her iPad.

The possibilities are endless. People are doing more and more from their mobile devices while on the go. This presents an ideal opportunity to connect with potential subjects as they use their smartphones and tablets throughout the day.

Mobile advertising has a place in every patient recruitment media plan.  Are you capitalizing on this exciting and rapidly growing medium for your recruitment efforts? Let the media team at CSSi provide you with a strategic media plan that is tailored to your study goals, location, and patient population using the right mix of traditional and new media.  Contact us to learn more!

CSSi Appoints Dr. William E. Gannon, Jr. to Newly Formed Medical and Clinical Advisory Board

August 18, 2014

Glen Burnie, MD—CSSi, the leader in patient recruitment solutions for the clinical research industry, recently announced the formation of the company’s Medical and Clinical Advisory Board (“MCAB”) and is pleased to announce the addition of Dr. William E. Gannon, Jr. to the MCAB.

  •    It was a long journey, and we are all delighted at the successful outcome. We appreciate the support [the CSS] team provided along the way. Hopefully, we can work together again in the future.

  •    You have made our advertising so much easier and taken time off my plate, which is always appreciated. We look forward to a prosperous relationship ahead!

    -Investigative Site
  •    …greatly appreciate your help throughout the year. You have taken a significant burden off my shoulders over the past several years.

    -Investigative Site
  •    I cannot begin to express my appreciation for a job well done and the continued efforts you place to ensure that this study was a success! Our candor and transparency has been refreshing and I am fortunate to have partnered with such a great group of patient recruitment and retention experts! You are wonderful!

  •     I wanted to take a moment and say thank you for continuing to do a great job and meeting our expectations. I could not be more pleased with the teamwork and efficiency in which you both approach (our) study!

  •    To begin with, please let yourteam know that everyone is doing a FANTASTIC job with compiling the information for this difficult study.

    -Top 10 CRO
  •    I would not hesitate to use CSS again! Your team has been an absolute pleasure to work with and I consider us friends as well. If you are ever in the Raleigh area, please let me know.

  •    We had the phones ringing off the hook for a few days, and we ended with approximately 60 individuals who sounded like viable screeners from the contact list. They are spread out over the next six weeks. Up to this time we have only screened about 30 others (before campaign) had 16 that were cultured and four successfully enrolled, so we are running about 11% from screen appointment to successfully enrolled! By the way, overall this is the best ad response we have ever had!

    -Dermatology Investigator
  •    If this sounds like a "paid advertisement" for CSS, it's not. I just can't say enough good things about how they have helped us grow as a site by putting our name out there in a very professional way. To me it only makes sense to use CSS or a company like them (I just think they are the best one). We are in the business of research, not advertising. Let the experts in advertising handle that job for your site and put your energy into doing what you do best…research.

    -Multi-specialty Investigative Site
  •    It is a PLEASURE working with the CSS team! I could not be more pleased with the progress thus far and feel that the communication and team oriented approach is EXACTLY what we are looking for.
