Mission and Vision


The mission of CSSi is to provide innovative patient enrollment and retention planning and performance designed to exceed our client's expectations. We achieve this mission by addressing the key factors in a successful patient recruitment campaign: the right strategy for the protocol and the right tools to complete enrollment on time and on budget.

Our goal is to help our clients conduct efficient and quality clinical trials while reducing enrollment timelines and cost by delivering strategic solutions that utilize our expertise in developing site-specific patient recruitment plans.

We Believe In Clinical Research.

We Believe In Clinical Research.


Today, Team CSSi is celebrating International Clinical Trials Day!  CSSi is proud to honor the extraordinary contributions of clinical researchers each year on May 20th, as we commemorate the day in 1747 that Scottish naval physician and pioneer in clinical trials, James Lind, began his famous trial in the treatment of scurvy.  The 20th of May marks the 268th anniversary of Lind’s clinical trial and is a day to recognize the contributions of organizations, clinical research professionals, and the public to the profound life changing achievements that result from the work performed by clinical researchers.

Lind's experiments in 1747 were run under very different conditions than what is done today. His trial was carried out at sea as he was serving as a surgeon on the HMS Salisbury. His trial consisted of just 12 men, grouped into pairs and given a variety of dietary supplements from cider to oranges and lemons. The trial only lasted six days but, within that time, there was a noticeable improvement in the group eating the fruit, providing Lind with evidence of the link between citrus fruits and scurvy. Clinical trials have developed a great deal since Lind's discovery, but today we remember his work and the importance of research in healthcare and he is regarded as the father of clinical trials.

Clinical researchers impact lives every day with their contributions to public health and medicine, and today we thank them for all they do for the advancement of clinical research. We also thank those medical heroes who take part in these trials for the greater good. 

Clinical research is something we fully embrace here at CSSi. Plain and simple, it can offer hope to those who may not have it.

Study Enrolls Three Months Ahead of Schedule when CSSi Goes the Extra Step in Special Population Recruitment

May 14, 2015

Glen Burnie, MD – CSSi, (www.CSSiEnroll.com) the leader in patient recruitment solutions for the clinical research industry, recently partnered with a major pharmaceutical company to support the recruitment and enrollment of a special population study. The overall enrollment goal was 1,200 patients using 110 sites within 12 months. The protocol required at least 15% (180) Hispanic and 20% (240) African American patients.

There were many challenges with this study, including competition for patients within this indication, lack of awareness about clinical trials, fragmented implementation of tools and tactics, need for education about the study, maintenance issues with screening activities at the site, and lack of study coordinator bandwidth to complete recruitment activities.

CSSi worked with each site to develop the most appropriate recruitment plan based on their patient population, local community demographics, and overall recruitment needs. CSSi developed a recruitment strategy for each of the different target audiences along with race specific messaging to be used with sites where the demographics were highly weighted toward the group. They utilized best practices in recruiting these special populations, including involving the investigators in the community, focusing on community-based outreach as it is a proven tactic for reaching people of Hispanic heritage.  Also, targeting African American patients with radio advertising, as it has been the most successful tactic for this population. Northern urban sites focused on African American populations while Southern sites focused on the higher density of Hispanic populations within these regions.

While targeting special populations with customized tools and tactics, CSSi contributed 634 non Hispanic/Caucasian patients representing 52 % of enrolled patients. 220 of the 180 patients who identified themselves as Hispanic were enrolled, and 346 of the required 240 African American patients were enrolled. There were high screening rates at 75% of the sites, due to custom enrollment planning, and this was the main reason for finishing the study three months early – meeting recruitment goals in nine months time.

  •    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.
