Scattered, Siloed, and Lost: The Case for a Portable TB Screening Record Every American Can Own

A Record That Belongs to No One

Somewhere in a filing cabinet at a college health center, a tuberculosis skin test result sits untouched. The student who received it graduated years ago, moved across three states, changed insurance twice, and has since visited a new primary care physician, an occupational health clinic, and an urgent care center — each of which had no way of knowing that test ever happened.

This is not an unusual scenario. It is, in fact, the norm for millions of Americans whose tuberculosis screening history exists somewhere in the healthcare ecosystem but remains practically inaccessible — to them, to their doctors, and to the public health professionals charged with preventing TB transmission. The result is a system that simultaneously overtests some patients while leaving others entirely unscreened.

The fragmentation of TB screening records is not a minor administrative inconvenience. It is a structural vulnerability that undermines the United States' capacity to identify latent tuberculosis infection, track high-risk individuals over time, and respond effectively when exposure occurs.

Why Continuity Matters in Tuberculosis Screening

Understanding why a portable TB screening record matters requires understanding how tuberculosis behaves in the body. Unlike many infectious diseases, TB can remain latent for years or even decades before progressing to active disease. A person exposed today may not develop symptoms for years. A positive tuberculin skin test result from a decade ago carries clinical significance that a new provider, seeing a patient for the first time, simply cannot access without documentation.

For patients in high-risk occupational categories — healthcare workers, corrections officers, teachers, social workers — annual or biennial TB screening is standard practice. Yet when these individuals change employers or providers, their prior results rarely follow them. Clinicians, unable to verify previous findings, often repeat baseline testing from scratch. This creates redundancy in some cases and dangerous lapses in others, particularly when a patient's most recent test was positive and that information never transferred to the new care setting.

The consequences extend beyond individual patients. Contact tracing efforts — already strained in many US jurisdictions — depend on knowing whether exposed individuals have been previously tested and what those results showed. Without that historical baseline, public health investigators are working blind.

What Other Countries Have Built

The concept of a patient-controlled health record is not novel, and several countries have moved well beyond the United States in implementing portable documentation systems that include infectious disease screening histories.

In France, the carnet de santé — a personal health booklet — has long served as a portable record that patients carry and present at each clinical encounter. More recently, digital adaptations in several European Union member states have created interoperable electronic health records that allow providers across institutions to access a patient's screening and vaccination history with appropriate consent.

Australia's My Health Record system, while imperfect and subject to legitimate privacy debates, demonstrates that a population-scale digital health record infrastructure is achievable within a federated healthcare environment. Patients can access their records, share them with providers, and maintain a longitudinal view of their health history — including diagnostic test results.

These models are not without flaws, and direct transplantation to the US context would require significant adaptation. But they demonstrate a fundamental truth: the technical capacity to build portable screening records exists. What has been lacking in the United States is the policy architecture and political will to implement it.

The American Barriers Are Real — But Not Insurmountable

The United States faces genuine structural challenges that complicate the creation of any national health record system. The healthcare landscape is fragmented across thousands of independent providers, hospital systems, insurance networks, and public health agencies, each operating on different electronic health record platforms with limited interoperability.

Privacy concerns, particularly under the Health Insurance Portability and Accountability Act, create legitimate caution around centralized data systems. Patients and advocates have historically raised valid objections to health data aggregation, citing risks of discrimination and surveillance.

Yet these barriers are not arguments against a portable TB screening record — they are arguments for designing one carefully. A patient-controlled model, in which individuals hold their own screening history and choose when and with whom to share it, sidesteps many of the centralization concerns. Several digital health platforms already allow patients to aggregate and share portions of their medical records. Expanding this to include standardized TB screening documentation is a technical challenge, not a conceptual impossibility.

Federal investment in this area has been modest. The HITECH Act and subsequent Meaningful Use regulations pushed healthcare systems toward electronic records but did not prioritize infectious disease screening continuity as a specific interoperability goal. A targeted policy intervention — requiring standardized, exportable TB screening documentation as part of federally funded health programs — could shift that calculus without requiring a wholesale overhaul of the existing system.

What a Portable Record Would Actually Look Like

A functional TB screening passport need not be a complex document. At its core, it would contain the date of each tuberculin skin test or interferon-gamma release assay, the result, the administering provider, and any follow-up actions taken. For patients with a history of positive results, it would include documentation of chest imaging, clinical evaluation, and treatment if applicable.

This information, stored in a standardized format and accessible via a secure patient portal or even a printable document, would allow any provider to immediately understand a patient's TB history without repeating baseline testing unnecessarily or, more critically, without missing a prior positive result that demands clinical attention.

For occupational health settings, where TB screening is legally mandated in certain industries, such a record would reduce administrative burden and improve compliance tracking. For public health departments managing contact investigations, it would provide an immediate baseline for exposed individuals. For patients themselves, it would represent something the American healthcare system rarely offers: genuine ownership of a piece of their own health history.

The Urgency of Getting This Right

Tuberculosis rates in the United States have risen in recent years following decades of progress. The populations at highest risk — recent immigrants, unhoused individuals, incarcerated persons, and those with immunocompromising conditions — are also those most likely to move between healthcare systems and least likely to maintain continuous relationships with a single provider.

For these populations, a portable TB screening record is not a convenience. It is a potential lifeline. When a person experiencing homelessness presents at a clinic they have never visited before, a provider who can immediately access that individual's TB screening history is far better positioned to make sound clinical decisions than one who must start from zero.

The technology exists. The models exist. The clinical rationale is clear. What remains is the institutional commitment to treat TB screening records as the essential public health infrastructure they are — and to build a system that ensures those records travel with the patients who need them most.
