Did you hear the one about the unstamped patient recruitment postcard? Oh, never mind. You wouldn’t get it …

But all joking aside, we know that “getting it” is the most important part of any patient recruitment effort. In a media universe that includes television, radio, and print, as well as social networking with Facebook and Google, it’s easy to overlook the most basic recruitment tool available: Direct Mail.

Unlike large-scale marketing offered by broadcast and the internet which reach broad populations, Direct Mail is highly targeted to the individual. After all, it’s delivered right to the patient’s home. Mail is hard to ignore, since a person checks for its delivery every day. Mail is also sorted almost immediately, so your message is directly in the hands of your prospective patient.

More importantly, the real key to a successful direct mail campaign is fresh, quality data. That data includes not only a patient’s address and zip code and key demographics such as gender and age, but possibly a raft of other customized data, such as self-reported lifestyle clues (e.g. smoker/non-smoker, enrolled in a weight-loss program) as well as self-reported medical conditions (e.g. asthma, arthritis). The opportunity for customized patient recruitment targeting is impressive.

And lest you think that a direct mail postcard via snail mail is terribly old-school and boring, well there is always Direct Email. The data is just as highly targeted to individuals who have opted-in to receive electronic notices. In addition, permission-based email recruitment allows for unique follow-up messages to likely patients. One caveat, however, is that this marketing tool is still fairly new and unproven for all patient recruitment, with the biggest hurdle simply being unable to target populations with specific medical conditions. The big data currently available might work best with large chronic conditions like double chins, cat allergies, or headaches as opposed to rare and/or genetic diseases.

At CSSi, we craft compelling and persuasive recruitment messages for your Direct Mail campaign. Our data resources are current and detailed. Give us a call to discuss if Direct Mail is the right option for your next clinical trial.

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

  •    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!

  •    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.
