  ABSTRACT: Enrolling in clinical trials could be time-sensitive and time-demanding tasks for the research site, especially if it is a private research organization compared to the research conducted at an academic or medical center. Every study differs in various aspects, such as phases, study indication, eligibility criteria, etc. In terms of meeting the enrollment deadline, typically, the study indication and availability of the patient’s population at the geographical area of the research site would decide if the trial could be time-consuming. Patient recruitment and retention are critical for the success of every clinical trial; however, worldwide, this area is facing tremendous pressure and challenges. Globally 55% of clinical trials terminated due to low recruitment, with an average enrollment success rate of 40% for Phase III and IV trials. Over 80% of clinical trial attempts fail to enroll, extending the study and adding new study sites. In the United States, more than 80% of clinical trials fail to achieve targeted patient enrollment, and 30% of study participants discontinue participation. This article reviewed various factors hindering clinical trial recruitment and retention and suggested strategies to make the research site successful.
