For twelve months, Kim took unpaid leave from work to drive her husband three hundred miles to a specialist research facility every other week. The routine became relentless. Long motorway journeys, endless waiting rooms, and overnight stays in the front seat of her car replaced any sense of normal life. Hotel costs were simply too high, so she wrapped herself in a thin blanket and tried to sleep while preparing to do it all again the next morning. Throughout that year, Kim remained a constant presence within the study, yet no one from the research team ever asked how she was managing or whether she needed support herself. She would repeat the experience without hesitation because the trial represented the only remaining source of hope. Kim’s story is not unusual. It reflects a wider system that recognizes the patient but overlooks the person making participation possible. If clinical research genuinely aims to build stronger partnerships with patients, it must also acknowledge the people quietly carrying the process forward behind the scenes.
Behind nearly every successful participant is a caregiver holding the practical and emotional structure together. Caregivers drive patients to sites, manage medications, handle insurance, provide emotional support, and often make the participation decision possible. Yet they are invisible in trial design and operations. By overlooking the physical, emotional, and financial pressures placed on caregivers, clinical trials risk undermining both patient well-being and study continuity. Supporting patients effectively requires recognizing the wider support network that sustains them.
The growing conversation around the clinical trial caregiver highlights the need for a more human approach to research. Patients do not navigate trials in isolation. Their ability to take part often depends entirely on the resilience and availability of another person. Recognizing this reality is essential if the industry wants to improve both patient experience and long-term retention.
The Role of the Clinical Trial Caregiver in Modern Research
The responsibilities of a clinical trial caregiver extend far beyond providing transport to appointments. Caregivers often become the connection between the research site and the realities of daily life at home. They monitor symptoms, help manage side effects, organize medication schedules, and ensure that complicated protocols are followed correctly. In many cases, they also provide emotional stability during periods of stress and uncertainty. Parents of children in rare disease trials face the most intense version of every challenge. They are making life-altering decisions for someone who cannot consent for themselves, often while managing complex care needs and navigating school, work, and family life.
Despite the importance of this role, caregivers are frequently absent from the early planning stages of a trial. Discussions around patient-focused research often concentrate solely on the patient without considering the wider environment supporting them. Yet a truly patient-first study must also account for the practical realities facing spouses, parents, or family members involved in the process.
When caregivers become overwhelmed, the impact extends directly to the patient. Exhaustion, financial strain, and emotional burnout increase the likelihood of missed visits or withdrawal from the study entirely. Including caregivers as active contributors rather than passive observers allows research teams to gain valuable insight into the daily realities of living with illness. Their perspective often reveals challenges that formal protocols alone cannot capture.
Addressing the Financial and Emotional Reality of Caregiving
For many families, the hidden costs of trial participation become one of the greatest barriers to staying enrolled. While patients may occasionally receive compensation for their time, caregivers often absorb the broader financial impact without support. Travel costs, lost wages, childcare, and out-of-pocket expenses can run into the thousands over the course of a trial. Stipends, when they exist, rarely cover actual costs. For rare disease trials requiring cross-country or international travel, the burden is exponentially higher.
Alongside these financial pressures sits the emotional strain of supporting someone through chronic or life-threatening illness. The constant balancing act between caregiving responsibilities and personal wellbeing can become unsustainable. Yet these realities are rarely discussed openly during recruitment or onboarding. Caregivers describe living in constant anxiety, grateful for the trial opportunity but terrified of adverse events, uncertain outcomes, and the possibility the treatment will be taken away at trial’s end. There are almost no mental health resources built into the trial experience for caregivers.
Transparency is critical in addressing this imbalance. Research teams should communicate clearly about available support while actively identifying ways to reduce unnecessary burdens. Assuming that families will simply find a way to cope creates significant inequality, particularly for those already facing financial hardship. Without better support systems, clinical research risks excluding entire groups of people who cannot absorb these hidden costs.
The Impact of Caregiver Burden on Clinical Trials and Retention
Studies of caregiver burden in clinical trials consistently reveal how rigid study structures contribute to stress and burnout. Up to 30% of trial dropouts have caregiver burden as a contributing factor. When the caregiver breaks down, participation becomes impossible. This is a retention problem hiding in plain sight. Long appointments scheduled exclusively during working hours force caregivers into impossible decisions between employment responsibilities and supporting a loved one. Over time, this pressure affects both the caregiver and the patient.
The same research shows that stress within the home environment can influence adherence, emotional well-being, and overall study experience. To keep people in studies to the end, the industry must simplify participation for the entire family unit rather than focusing solely on the patient. Much of that burden is predictable before day one: a family that understands what a study will ask of them, in miles, hours and money, can decide with open eyes rather than discover it visit by visit.
Small operational changes can make a significant difference. Trials should offer dedicated caregiver liaisons, travel and lodging support, mental health resources, flexible scheduling, respite care options, and simple acknowledgment that caregivers exist and matter. Hybrid and decentralized models can dramatically reduce caregiver burden by bringing the trial to the patient. This is a concrete reason to support innovation in trial design. Telemedicine appointments, home-based monitoring, and mobile nursing support can reduce the frequency of exhausting long-distance travel, easing the burden on families already under strain.
Systemic Changes to Support the Patient Support Network
Creating more inclusive clinical trials requires structural change at the design level. One of the most effective ways to achieve this is through co-creation. Including caregivers in focus groups and protocol discussions during trial development helps identify barriers that researchers may never encounter themselves.
A caregiver might highlight how a treatment schedule conflicts with school pickups or explain why repeated long-distance travel is unrealistic for families managing mobility limitations. These insights provide practical guidance that can improve both recruitment and retention. When protocols are designed with real-life circumstances in mind, participation becomes more sustainable for everyone involved.
Measuring trial success should also evolve beyond clinical endpoints alone. The well-being and experience of the support network matter because they directly influence study continuity and data quality. Caregivers who feel informed, respected, and supported are more likely to stay with the study to the end. This creates a more stable environment for patients and strengthens the integrity of the research itself.
The invisible crisis surrounding caregiving in clinical research can no longer remain unaddressed. Every spouse sleeping in a car and every parent missing work to attend appointments represents a gap in the system’s understanding of patient support. By designing trials around the realities of the whole care network, the industry can create a more ethical, compassionate, and effective research environment.
Caregivers have always been essential to the success of clinical trials. The next step is ensuring that research systems begin treating them that way.

About the author
Keith Berelowitz has spent more than twenty years watching clinical trials work on paper and struggle in real life. He has helped run studies, advises sponsors and CROs on how they engage with people, and chairs a UK research ethics committee, where consent forms and participant information sheets cross his desk every month. That vantage point led to one conclusion: most trial problems are not failures of science. They are failures of understanding at the moment a person decides.
He founded trialport, a clinical trial navigation and decision-support platform, to help people weigh a trial in the context of real life rather than on paper alone. Its medifit™ + readifit™ self-reflection tools ask two questions: Is this trial right for my health? Is this trial right for my life? Understanding comes first. Decisions follow.
