Clinical trials remain the backbone of medical innovation, yet the industry continues to face a persistent and costly paradox: despite unprecedented scientific advancement, most trials struggle to enroll and retain participants. The data is sobering. Nearly 80% of clinical trials experience delays or premature termination due to recruitment challenges, and 37% of research sites fail to enroll an adequate number of volunteers with 11%enrolling none (Clinical Trials.gov).
At Sikara, we believe the industry must shift from reactive enrollment tactics to proactive, system‑level readiness. This requires rethinking feasibility, redesigning workflows, and elevating research as a strategic asset within health systems.
Why Patients Disengage
Modern protocols are more ambitious than the infrastructure meant to support them. Limited resources, financial constraints and operational burden make it challenging to meet enrollment targets for many sites.
- Randomized Clinical Trials are more complex with restrictive criteria, complex assessment and multiple amendments.
- Hyper restrictive eligibility criteria: Challenging inclusion and exclusion criteria shrinks the pool of qualified patients and forces sites to screen out large numbers of interested individuals.
- Complicated visit schedules and assessments: Oten requires multiple specialists, advanced imaging, or long appointment blocks that sites cannot accommodate.
- Multiple protocol amendments: This is a burden that forces sites to retrain staff, rescreen patients, and reconfigure workflows mid trial.
Most patients never enter the pipeline because they never hear about the trial in the first place as there is little to no awareness of clinical trials or research in communities.
- Limited clinical trial awareness campaigns: Health systems don’t invest in campaigns leading to lack of awareness in the community. Digital marketing is underutilized, despite being the most efficient way to reach diverse, geographically dispersed populations.
- Shallow community partnerships: Limited presence of research individuals in trusted spaces like churches, mosques, barbershops, cultural centers, and local clinics creates gaps.
- Cultural issues: Messaging is often not culturally sensitive thereby failing to resonate with communities historically excluded from research.
Underrepresented communities face structural barriers that are rarely addressed upstream.
- Inconsistent language access: Translated materials are often unavailable or poorly adapted.
- Varied cultural competence: Cultural insensitivity leads to unintentionalmicro exclusions in communication and care.
- Unrecognized health literacy: A challenge especially when materialsassume a high baseline understanding of medical terminology.
- Historical mistrust: Ignoring mistrust in clinical trials leaves patientswithout the reassurance they need to feel safe participating.
CRC burnout is at an all-time high,driven by unrealistic workloads and administrative burden. When staff areoverwhelmed, patient engagement inevitably suffers.
- Fragmented workflows: Slow process from prescreening to scheduling to documentation.
- Inconsistencies creating delays in clarifications, approvals, and decision making.
- Staff turnover: Site staff attrition can be high, forcing sites torebuild institutional knowledge.
- Low System Investment: Sites are not fully resourced or financed to besustainable.
Technology should streamline research. Instead, it often complicates it. Fragmentation creates friction at every step of the upstream journey.
- Sites juggle multiple platforms: eConsent, eReg, ePRO, CTMS, EHR system with its own login, training, and workflow.
- Disparate systems: Lack of integrated systems requires duplicative dataentry and manual reconciiation, creating unneeded work and errors.
- Inadequate Training: Education and Training programs are insufficient, leaving staff unsurehow to use tools efficiently. efficiently.
- Disjointed platforms: Patients must use multiple clunky portals andconfusing apps to make decisions and enter data.
Retention begins long before the first study visit, but most strategies start too late.
- Transportation challenges: When unaddressed, especially for elderly orlow income patients, these are real challenges.
- Family needs: Family is critical for sustained participation, but needsare overlooked.
- Patient fatigue: Complex protocols, long screening periods and multiplepre-enrollment steps lead to tiredness and fatigue.
- Follow up: If not properly done, it leaves patients feeling forgotten orundervalued.
The Sikara Framework for Clinical Trial Success
Most enrollment failures can be traced back to feasibility decisions made months before the first patient is approached. True readiness requires a multidimensional assessment and not a checkbox exercise.
- Staffing and Workload Mapping: Evaluate coordinator to trial ratios,acuity productivity models, competing studies, turnover risk, and protectedresearch time.
- Infrastructure and Workflow Maturity: Assess scheduling capacity, accessto imaging and labs, EHR integration, and availability of decentralizedcapabilities.
- Governance and Regulatory Strength: Review IRB turnaround times, SOPmaturity, QA processes, and audit readiness, IRB review- external vs. internal.
- Operational Capacity Forecasting: Move beyond historical enrollmentnumbers to assess real time bandwidth, bottlenecks, and throughput potential.
- Early Site Engagement in Protocol Codesign: Invite sites into feasibilityconversations early to surface operational risks and build ownership
Enrollment projections often reflect optimism rather than operational reality. A modern approach requires precision.
- Balanced Portfolio Strategy: Combine high volume academic centers withagile community sites that reach diverse populations.
- Data Driven Modeling: Use epidemiology, EHR based prevalence data, andhistorical performance trends to set achievable goals.
- Dynamic Target Adjustment: Reassess targets at key milestones - postfirst patient in, after protocol amendments, or when site conditions change.
Risk Adjusted Forecasting: Incorporate variables such as staff turnover,competing trials, and seasonal patient flow.
- Patient engagement must be omnichannel, culturally grounded, and continuous, not episodic.
- Digital Marketing at Scale: Use targeted social media, search optimization, and geofenced campaigns to reach patients where they already are.
- Community Rooted Partnerships: Build trust through collaborations with churches, mosques, barbershops, community health workers, and local clinics.
- Culturally Relevant Messaging: Tailor materials to reflect community values, languages, and lived experiences.
- Multilingual, Accessible Consent Processes: Offer interpreter services,plain language summaries, and multimedia consent tools (videos, infographics, interactive modules).
- Continuous Engagement, Not One Time Outreach: Maintain touchpoints from awareness to pre-screening to enrollment.
Technology should simplify, streamline, and empower and not overwhelm.
- AI Powered Pre Screening and Patient Matching: Automate eligibility checks, reduce manual chart reviews, and accelerate identification of qualified patients. • Unified Digital Patient Experience: Mobile apps that consolidate reminders, educational content, visit schedules, and communication channels.
- Integrated Tech Stacks: Harmonize eConsent, eReg, ePRO, CTMS, and EHRsystems to eliminate duplicative data entry and reduce training fatigue.
- Interoperability as a Core Requirement: Select tools that speak to eachother Human Centered Design: Ensure interfaces are intuitive for both staff andpatient
Coordinators are the backbone of clinical research. Empowering mid-level managers and clinic staff will improve clinical outcomes.
- Continuous Training and Protocol Mastery: Provide structured onboarding,micro learning modules, and scenario based training.
- Cultural Competency and Communication Skills: Equip staff to engagediverse populations with empathy and clarity.
- Decision Making Autonomy: Establish clear escalation pathways so CRCs canresolve issues quickly without waiting for manager or sponsor approval.
- Workload Protection and Burnout Prevention: Implement staffing modelsthat prevent overload and support retention.
- Recognition and Career Pathways: Elevate CRC roles through professionaldevelopment and leadership opportunities.
Patient support services are not “nice to have” but essential infrastructure for equitable participation.
- Transportation Solutions: Rideshare partnerships, vouchers, mileage reimbursement, or mobile units that bring the trial to the patient.
- Patient Navigators: Dedicated guides who help patients understand theprocess, manage logistics, and stay engaged.
- Family and Caregiver Support: Childcare options, flexible visit times,and resources for caregivers.
- Decentralized and Hybrid Options: Telehealth visits, home healthservices, mobile phlebotomy, and remote monitoring to reduce burden.
- Flexible Scheduling: Evening and weekend appointments to accommodate workand family commitments.
The Future of Enrollment Depends on Upstream Excellence
The enrollment crisis is not inevitable. It is the predictable result of fragmented systems, under‑resourced teams, and outdated assumptions about research’s value. The solution lies in readiness, infrastructure, technology, and leadership alignment.
At Sikara, we believe the future belongs to organizations that:
- invest in operational and cultural readiness
- empower their people
- modernize their technology
- elevate research as a strategic pillar of care delivery
These are the systems that will lead in innovation, equity, and patient impact.
