Why the Data You See Is Only Half the Story

Needlestick injuries (NSIs) remain one of the most prevalent occupational hazards in healthcare, yet institutional data captures only a fraction of their true frequency. The reason? Underreporting. Despite well-documented risks and formal protocols, frontline clinicians often choose not to report NSIs, whether due to workflow barriers, fear of professional consequences, or cultural normalization of risk. This silent epidemic threatens the safety of providers and hinders meaningful prevention efforts.

The Hidden Epidemic: How Big Is the Problem?

In a large study of healthcare workers in China, 28.5% of all NSIs went unreported, despite a 32.9% incidence rate across the surveyed cohort [1]. These findings mirror international data. Across a range of hospital systems, underreporting rates reach as high as 64.7%, often driven by poor familiarity with reporting procedures, time pressure, and a lack of perceived importance [2].

Physicians are among the most likely to underreport. In one hospital system, 42.7% of doctors performing invasive procedures failed to report NSIs, even though physicians accounted for nearly 59% of all underreported cases [3]. These statistics suggest that what appears as low incidence in institutional dashboards may, in fact, reflect systemic silence rather than true safety.

Why So Many NSIs Go Unreported

Clinicians often dismiss NSIs when the exposure seems minor or the patient appears to pose low risk for bloodborne disease. Even in environments with clear reporting protocols, the required documentation process is frequently cumbersome, lengthy forms, required follow-ups, and disruptions to clinical workflow can discourage even motivated staff from reporting.

‍

Beyond practical hurdles, psychological and cultural barriers play a role. Fear of being judged, concerns about professional reputation, and the belief that an incident reflects carelessness all suppress disclosure. In many healthcare environments, especially those that normalize risk—reporting may be perceived as unnecessary or even career-damaging.

Consequences of Underreporting

When NSIs go unreported, post-exposure prophylaxis may be delayed or missed altogether, especially in high-risk exposures where timing is critical. Institutional blind spots in data collection mean unsafe behaviors or practices may go uncorrected. Without accurate statistics, health systems fail to plan, train, or procure safety devices appropriately. The financial and legal consequences also mount, untracked exposures can translate to unbudgeted expenses, increased liability, and lost opportunities for safety improvement.

Breaking the Silence: What Works

The first step toward reversing underreporting is simplifying the process. When reporting tools are embedded into electronic health records (EHRs), mobile devices, or clinical dashboards, the burden of documentation is reduced. Creating a non-punitive culture around injury reporting is equally essential. Confidentiality must be preserved, and transparency should be rewarded, not penalized.

‍

Education remains a key driver. Staff must be reminded that all NSIs matter, whether superficial or deep, whether involving high-risk patients or not. Training should emphasize that reporting is not an admission of failure but an act of protection, for the individual, their colleagues, and the broader system.

‍

Leadership must also play a visible role. By reviewing trends, sharing anonymized insights, and acting on feedback, clinical and administrative leaders signal that reporting drives action.  Engineering controls should complement this effort. Intuitive devices like HypoHolder, a Class I FDA-registered tool designed for one-handed hypodermic needle handling, can reduce exposure risk during recapping, uncapping, and disposal, while fitting seamlessly into existing workflows.

Reporting Is the First Line of Defense

Unreported NSIs are not isolated oversights, they are systemic vulnerabilities. Without full visibility, healthcare institutions cannot identify failure points, deploy effective solutions, or protect their staff. It is only through cultural transformation, simplified processes, and consistent deployment of innovative tools that organizations can fully address this risk.

When healthcare professionals speak up, systems learn. And when systems learn, safety improves, for everyone.
