Reporting Inpatient Hospitalizations to OSHA: Common Misunderstandings and Mistakes


By Eric J. Conn

The regulatory requirement at 29 C.F.R. 1910.39, OSHA’s Fatality and Serious Injury Reporting Rule, which requires employers to report to OSHA certain inpatient hospitalizations, may seem straightforward, but there are several nuances employers routinely miss that affect the determination of whether a hospitalization is actually reportable to OSHA.

Although failing to timely report a reportable hospitalization can be cited, and could set up an employer for costly “Repeat” violations, over-reporting has its own significant consequences. Reporting hospitalizations very often triggers an on-site enforcement inspection, and OSHA issues a citation at least 75 percent of the time it conducts an inspection (an even higher percentage for incident inspections). Moreover, at least 85 percent of OSHA citations are characterized as “Serious,” “Repeat” or “Willful,” and OSHA’s civil penalty authority has skyrocketed by 80 percent in the past two years.

It is critical that employers understand the intricacies of what makes an employee’s visit to the hospital a reportable event, and conversely, what does not, so as to avoid unnecessary and costly reports to OSHA.

Accordingly, it is critical that employers understand the intricacies of what makes an employee’s visit to the hospital a reportable event, and conversely, what does not, so as to avoid unnecessary and costly reports to OSHA.

Under the current reporting requirements, employers must:

“within 24 hours after the in-patient hospitalization of one or more employees [that occurs within 24 hours of the work-related incident] . . . report the in-patient hospitalization . . . to OSHA.”

This is a significant change from the prior reporting rule, which required a report to OSHA only if three or more employees were hospitalized overnight. It was extraordinarily rare that a single workplace incident resulted in the overnight hospitalization of three or more workers, and so the instances of reporting under that rule were infrequent. The new rule, however, requires a report to OSHA for the hospitalization of a single employee, which has opened the door to thousands more incidents that must be evaluated for possible reporting.

Although the current regulation has increased the number of employee hospitalizations that are being reported to OSHA, many of those incidents reported to OSHA did not actually meet the criteria for reporting, based on a very particular definition of hospitalization and a limited time period for when the hospitalization must occur. In other words, many incidents are being reported to OSHA (effectively inviting OSHA to conduct a site enforcement inspection) that should not have been reported at all.

What Is an “Inpatient Hospitalization”?

Under the old requirement to report the hospitalization of three or more workers, the operative analysis was whether the employees stayed overnight at the hospital. The new regulation lowers the employee count from three or more to just a single employee, but more importantly, redefines the term hospitalization from an overnight stay to the “inpatient hospitalization . . . for care or treatment.” Let’s take that in parts.

First, as defined by the regulation, an inpatient hospitalization occurs only upon:

“formal admission into the in-patient service of the hospital or clinic for care or treatment.”

Based on the plain language of the regulation and guidance issued by OSHA about what it means, there are two limiting elements that must be present for a visit to the hospital to be an “inpatient hospitalization”:

  • Formal admission to the inpatient service of a medical facility; and
  • Delivery of medical care or treatment after formal admission.

Therefore, to meet the definition of an inpatient hospitalization, the employee must move beyond the emergency room and emergency status at the hospital to a formal admission to the inpatient service. On top of that, medical care or treatment must be provided after that formal admission to the inpatient service. For instance, if an employee loses consciousness at work and is admitted to the inpatient service of the hospital for an MRI to diagnose what caused the loss of consciousness and for observation for additional symptoms, but no medical treatment is provided, that hospitalization is not reportable.

Importantly, in the context of evaluating an inpatient hospitalization, the language of the standard does not limit “care or treatment” to “medical treatment beyond first aid,” as it does for recording injuries on the 300 Log, and OSHA clarified in FAQs for the reporting requirements that an inpatient hospitalization “involving any treatment,” even if just first aid, must be reported to OSHA.

Does Timing and the Sequence of Events Matter?

The timing and timeline of an inpatient hospitalization is critical in determining whether a visit to the hospital is reportable to OSHA. First, medical treatment or care given prior to formal admission into inpatient services does not constitute a reportable hospitalization under 29 C.F.R. 1910.39(a)(2). Not only must an employee be admitted to the inpatient service for an injury to be reportable; the hospitalization is only reportable to OSHA if medical treatment is provided after the admission. Major medical care provided to an injured worker only in the emergency setting is not reportable.

For example, if an employee breaks his or her leg and is taken to the emergency room (i.e., not the inpatient service of the hospital), where he or she receives emergency surgery to set the leg and prescription drugs for pain before being released, this incident is not reportable because there was no admission to the inpatient service. This is also true where an employee receives substantial medical care in the emergency service prior to being formally admitted inpatient, if the subsequent admission involves only observation. In the same broken leg scenario as before, if rather than being released from the emergency service, that employee is admitted to the inpatient service but only for observation for potential infection from the surgery, that incident is also not reportable to OSHA, because the employee did not receive medical care beyond observation after being admitted inpatient.

Major medical care provided to an injured worker only in the emergency setting is not reportable.

Second, the reporting rule limits employers’ duty to report inpatient hospitalizations to those hospitalizations that occur within 24 hours of the work-related incident. More specifically, for a hospitalization to be reportable to OSHA, an injured employee must move beyond the emergency service to a formal admission to the inpatient service, and then receive medical treatment while in the inpatient service, all within 24 hours of the incident. Surprisingly, that has turned out to be a very limiting criterion.

Without getting too cynical, let’s just say that our healthcare system in the U.S., or more specifically, our health insurance payment/reimbursement system, creates unusual incentives. Medical providers are reimbursed by insurers at a higher rate for the same medical service, if that service is delivered in the emergency context, as opposed to in the inpatient service. Accordingly, hospitals tend to keep patients in emergency status as long as they are permitted under the insurance scheme. Time from the site of an injury and wait times at emergency rooms can also be surprisingly long.

Accordingly, it is shockingly common for the formal admission to the inpatient service to occur more than 24 hours after the incident that caused the injury. In those circumstances, the injury is not reportable to OSHA regardless of the scope of medical treatment provided to the injured employee after admission to the inpatient service.

Likewise, instances where medical treatment is deferred for a day or two after an incident (e.g., surgery delayed until swelling reduces) is not reportable provided no other medical treatment was provided in the inpatient setting during the delay.

When Do the Various Reporting Time Clocks Start Ticking?

Similar to reporting fatalities or amputations, an inpatient hospitalization must be reported to OSHA within 24 hours. A key question (and a particularly tricky issue in the context of hospitalizations) is what triggers that 24-hour reporting window. The 24-hour time clock to report to OSHA begins when the employer, or any agent of the employer (i.e., any supervisory employee), obtains knowledge that a reportable event has occurred. The regulation recognizes that an employer may not always have immediate knowledge that an injury meets the reporting criteria, especially hospitalizations.

Knowledge of a fatality or amputation are usually self-evident at the workplace when the incident occurs. However, because of the nuances discussed above about whether a hospitalization is reportable, and the fact that key circumstances for determining whether a hospitalization is reportable occur outside the workplace, the precise moment in time when an injury becomes a reportable hospitalization and when an employer attains actionable knowledge of that fact, are often not immediately available after an incident has occurred.

Obviously if an injury and hospitalization occur without the employer being notified, the employer’s reporting obligation would not kick in until it is notified or otherwise becomes aware after reasonable inquiry/investigation by the employer. For instance, if two employees are working in a shipping area, one cuts open his hand trying to open a box, and, without notifying management, his co-worker drives him to the hospital where he is admitted for treatment, the 24-hour reporting clock does not start at the moment of the incident. Rather, the employer would have 24 hours to report the injury to OSHA from the time the employer is either notified or independently becomes aware of both the injury and the resulting inpatient admission for treatment.

Similarly, even if the employer knows the employee was taken to the hospital, but does not learn about the formal admission for several hours (or days), either because the admission itself is delayed, or because the employer cannot obtain information from the hospital or the employee, the start of the 24-hour reporting clock does not begin right away. As above, the 24-hour timeframe in which the hospitalization must be reported would not start until the employer learns the hospitalization meets the reporting criteria.

Note, however, employers may not bury their heads in the sand. Reasonable inquiry is required, and employers will need to demonstrate what steps that have taken to learn the circumstances of the hospitalization, whether it be efforts to contact the employee or the hospital.

One final point about timing: It is usually easier to determine whether a qualifying hospitalization has occurred within 24 hours of a work-related injury than it is for a work-related illness. When the impetus for a hospitalization is an illness, determining whether the hospitalization occurred within 24 hours of the incident can be challenging. In that case, the triggering event is the time when the employer can best discern the employee was exposed to the chemical, contagion, bacteria or other work-related condition that caused the illness.

For example, on Oct. 1, Employee 1 worked in close proximity with Employee 2 to develop a training presentation. On Oct. 2, Employee 1 calls out of work with a staph infection. On Oct. 4, Employee 2 is admitted into the inpatient service at a hospital and receives medical care for a staph infection. Employee 2’s staph infection is likely work-related because she worked in close proximity to Employee 1, and that workplace exposure more likely than not contributed to his inpatient hospitalization. However, the employer can reasonably conclude that the triggering exposure that resulted in Employee 2’s hospitalization occurred on Oct. 1, while he worked with Employee 1. Therefore, the hospitalization is not reportable because the admission to the hospital occurred outside the 24-hour window from the work-related incident.

Is the Underlying Injury Work Related?

Another factor in determining whether and when a hospitalization becomes reportable to OSHA is determining whether the underlying injury is work-related. Under OSHA’s reporting rule, which is just a sub-section of OSHA’s broader Injury and Illness Recordkeeping regulation, only work-related fatalities, amputations and inpatient hospitalizations are reportable. If the employer determines that an injury that results in a hospitalization is not work-related, it is not reportable. Likewise, if it takes some time to determine, based on reasonable inquiry and investigation, that an injury resulting in a hospitalization is work related, the reporting clock only begins to tick when the employer learns the information necessary to make that determination.

For example, if an employee has a seizure at work and hits her head on a desk, causing a laceration, and the laceration is treated after admission into inpatient service, the hospitalization is not reportable to OSHA if the employer determines that the seizure was caused by a non-work-related condition, such as epilepsy. Conversely, if the employer learns after three days of investigation, including industrial hygiene testing and consulting with the employee’s treating physician, that something in the work environment contributed in any way to her seizure, the hospitalization would be a reportable work-related hospitalization. However, the 24-hour window to report the incident to OSHA would not start to run until the employer learns the injury is work-related.

Getting It Right

Determining whether an inpatient hospitalization should be reported to OSHA, and by when, is not always clear, and the consequences of getting it wrong, either way, are serious. When an employee experiences an injury or illness that results in a visit to the hospital, an employer must determine, through reasonable inquiry and investigation, whether:

  • The employee was admitted to the inpatient service of the medical facility;
  • The employee received medical treatment beyond observation and diagnosis at the medical facility;
  • The medical treatment was provided after admission to the inpatient service;
  • The admission to the inpatient service and subsequent medical treatment occurred within 24 hours of the incident that caused the injury; and
  • The injury was work-related.

Only if the answer to all of those questions is yes, must OSHA be notified of the hospitalization, and that notification must be made within 24 hours of learning of the relevant information to draw that conclusion.

Accordingly, it is important to educate management representatives, particularly those charged with the responsibility to make reports to OSHA, about the nuances of OSHA’s reporting rule, and to consult with OSHA defense counsel before picking up the phone to call OSHA.
