In 2005, only 1 in 10 healthcare workers felt comfortable speaking up when they witnessed a colleague doing something potentially harmful. Today, that number has tripled.
A national survey of more than 3,500 clinicians and healthcare administrators, published in the American Journal of Critical Care, found that 32% of respondents now say they speak up when witnessing dangerous behavior among colleagues — up from just 10% two decades ago. The study, "Silence Kills 2.0: How Communication Failures Stifle Innovation and Harm Patients," was co-sponsored by Crucial Learning and the American Association of Critical-Care Nurses (AACN).
"Speaking up continues to be the vehicle for shaping the norms that govern behavior and results in health care," said Vicki Good, AACN's chief clinical officer and co-lead researcher. "Conversely, a failure to speak up indicates an absence of healthy norms that will inevitably impact patient safety and staff outcomes."
The findings reveal that this shift toward candor carries real weight. Researchers discovered that healthcare workers who speak up fully and directly — rather than hinting or staying silent — report better patient safety outcomes, improved patient experiences, and stronger clinical results. Perhaps just as importantly, those who communicate openly are significantly less likely to consider leaving their organization within the next six months, a finding that speaks to both workforce retention and the emotional toll of swallowed concerns.
But the study also surfaces work still ahead. Forty percent of healthcare workers report witnessing colleagues break rules at least weekly, and 22% witness outright mistakes in patient care with the same frequency. Of those who see these problems, only about half directly confront the person and fully express their concerns.
The research went further, probing how honesty affects innovation adoption. Teams with the highest candor scores — those in the top decile — are dramatically more likely to embrace new technology and clinical practices. Eighty-nine percent of these high-candor teams actively look for ways to improve patient outcomes and quality of care, compared with just 32% of lower-scoring teams. In an era when healthcare systems are racing to integrate AI and machine learning, the data suggests that cultural readiness may matter as much as technological readiness.
Joseph Grenny, co-founder of Crucial Learning and co-lead researcher, said the implications are clear for hospital and health system leaders. "Teams that routinely speak up appear more likely to quickly adopt new practices and technology," he said. "Leaders who create cultures where clinicians are both motivated and able to speak up in these common but costly situations will reap significant short- and long-term improvement."
The journey from 10% to 32% took twenty years. The researchers hope the next leap — toward environments where every voice is heard — won't take as long.
