Recruitment strategy is critical to the success of any clinical trial, as it ensures adequate participation and enables meaningful results to be obtained. This article reviews the key elements of the systematic three-tiered approach that any effective patient recruitment strategy must address: creating awareness of the study to attract the attention of potential participants; fostering the enrollment process; and ensuring retention and engagement.
Most investigators maintain or have access to a database of patients they see on a regular basis. This database/clinic list often is the first place where potential patients are pre-screened against the protocol requirements. In some countries, pre-screening can only be conducted after ethics committee (EC) approval of the study. Therefore, it is important to understand this caveat while reviewing the expected enrollment figures of study sites within these countries. Some examples of techniques used to create clinical trial awareness include:
The Principal Investigator (PI) may decide to approach colleagues (e.g., this maybe in the same department or other hospitals) who work in the same field as the indication under study and request patient referrals. Often, there are clinicians who are interested in conducting the trial and can be added as Sub-Investigators at the study site. In some cases, the PI may be afforded the opportunity to present the study to their colleagues as a means of creating awareness, which may also result in patient referrals. Some examples of techniques used to create awareness are listed below:
The doctor-patient relationship is vital in developing trust and confidence in the study team. This rapport may prove extremely important in whether the patient continues their participation in a study. The Informed Consent process is also an integral part of the clinical research process. This step ensures the patient is given enough time to review the trial information and that their concerns can be properly addressed. The ICF process is completed when both the doctor and the patient have signed the consent form. Subsequently, the patient will interact with the rest of the study team during study visits, until the end of the study.
The level of patient burden or inconvenience experienced by the patient whilst on the study may influence the clinical trial’s retention rate. To alleviate some of this burden, the following techniques can be employed:
Patient recruitment is everyone’s responsibility from CRAs, study nurses, Sponsor, CRO, pharmacy team and Principal Investigators. It is important that CRAs adopt a transparent and collaborative approach when interacting with study site staff. Experience shows that successful study sites are those who openly communicate with the Sponsor representatives about the challenges they are facing with the aim of working as a team to address any potential roadblocks. Thus, in addition to the three-tiered approach, it is vital to increase motivation at the study site level by applying some of the following techniques:
The CRA should always discuss with each study site before implementing some of the techniques suggested to keep in line with local regulations and requirements.
