World Health Day, observed every April 7th, is a global reminder that health is a fundamental human right — and that health means far more than the absence of disease. It encompasses emotional well-being, dignity, connection, and the ability to thrive, even in the most difficult circumstances.

For the seriously ill children and families we serve, health isn’t only measured in lab results and treatment milestones. It’s also measured in a child’s smile during a bedside music session or a moment of laughter with a trusted mentor. Joy, it turns out, is not a luxury. It is a vital and measurable part of a child’s well-being.

The Weight of a Hospital Stay

Hospitalization is profoundly hard for children who experience anxiety, fear, and social isolation in a formative time of their lives. Research shows that prolonged hospital stays disrupt a child’s emotional development, erode social connections, and can have lasting psychosocial consequences.

A 2025 study examined twelve randomized controlled trials and found that music interventions significantly reduced anxiety, fear, and pain levels in hospitalized children, concluding that music interventions are “safe and practical” supportive strategies that healthcare teams should consider integrating into pediatric care. These aren’t abstract findings — they reflect what our JoyRx Music Specialists witness every day. A child who was withdrawn and silent an hour ago is now requesting a favorite song. A parent who hadn’t exhaled in days finally does. The research and the real-world experience align.

A Physician’s Perspective on the Power of Joy

Few people understand the intersection of joy and healing more intimately than Lesley Otto, MD — a Physician & Surgeon at Providence Health and former member of the Children’s Cancer Association Board of Directors. With over thirty years of medical practice, Dr. Otto brings both clinical expertise and profound compassion to her role as a dedicated advocate for JoyRx Programs.

Her connection to the organization began with witnessing its work firsthand. The tangible difference she witnessed drew her in immediately.

“We as doctors recognize how critical well-being is to the healing process. Children’s Cancer Association is dedicated to bringing that joy to children.”
-Lesley Otto, MD

Dr. Otto served on the Board from 2018 to 2024, a period of significant growth for our programs. But her commitment didn’t end with her board tenure. She remains a devoted donor, supporter, and advocate — because she has seen, with her own eyes, what joy can do for a child navigating a serious illness. “A child’s smile says it all. The calmness says it all,” she shared.

What Our Own Data Shows

Children’s Cancer Association doesn’t just believe in the power of joy — we measure it. Over the past several years, we’ve partnered with expert evaluation consultants to develop custom assessment tools that capture the psychosocial impact of our JoyRx Music program from multiple perspectives: pediatric patients, parents and caregivers, healthcare staff, and our own music specialists.

Our approach was built on an extensive literature review and a needs assessment with pediatric healthcare administrators, resulting in a suite of digital surveys that assess well-being across domains, including youth social connection, emotional regulation, caregiver relief and empowerment, and staff support. Today, we achieve a 60% response rate on those surveys — a strong foundation for meaningful data.

The results are striking:

99% of hospital staff observe improved emotional regulation for youth

95% of hospital staff report a strong sense of child empowerment

97% of caregivers report a strong sense of relief during their JoyRx Music sessions

98% of hospital staff report that JoyRx Music positively contributes to their own emotional state

These numbers reflect something profound: joy is not just felt by the child in the room. It radiates and reaches everyone in the space experiencing a difficult moment.

Addressing Who Needs Joy Most

Our commitment to reaching children goes beyond the walls of any single hospital. In 2021, we partnered with graduate students from the University of California, Berkeley to analyze where our expansion could have the greatest impact. The research identified 10 states with the largest, most diverse, and highest at-need child populations, recognizing that patients of color make up a significant portion of inpatient populations, yet face persistent disparities in access to supportive care. That analysis now guides our growth strategy.

Over the past five years, JoyRx Music has reached 128% more children, spanning more than 20 states. As we grow, we are also developing site-specific PULSE reports for each of our healthcare partners while providing detailed, localized data on the reach and outcomes of JoyRx Music at their facility.

What World Health Day Means for Seriously Ill Children

This World Health Day, we invite you to think about what “health” means for a child who spends weeks or months in a hospital room. For these children, health means having agency and being able to request an instrument or decide what game to play with a mentor. It means feeling like a child, not just a patient.

Our JoyRx Music, Mentorship, and Nature programs are designed with this broader definition of health in mind. Each program is trauma-informed, grounded in research and best practices, and aligned with pediatric healthcare goals, addressing the emotional dimensions of a child’s health journey.

“These programs reinforce the beauty of human connection and a loving community’s values. We need to take care of our most vulnerable. We need to make people feel safe. To help others find that calmness and, maybe, even joy. Through music, friendship, and nature, Children’s Cancer Association achieves that — and what’s more beautiful than that?” – Dr. Otto
