Havana Syndrome: Better Patient Communication and Monitoring of Key DOD Tasks Needed to Better Ensure Timely Treatment

What GAO Found

U.S. government employees and family members in several countries have experienced a sudden onset of symptoms referred to as anomalous health incidents (AHI). GAO interviewed 65 AHI patients, who reported a variety of challenges in accessing the Military Health System (MHS). They included inconsistent support from home agencies before seeking MHS treatment, limited information and unclear points of contact upon entering the MHS, and difficulty scheduling appointments when using the MHS. According to officials, civilian AHI patients are not as familiar with the MHS as active-duty military and need additional support to navigate the system. In addition, the Department of Defense (DOD) lacks an official mechanism to communicate authoritative information to AHI patients, which led some to use informal support groups to navigate the MHS. While some patients found these groups valuable, other patients and DOD officials noted these groups sometimes communicated inaccurate information. For example, some officials reported misinformation in the groups about the availability of appointments in the MHS. Without an official DOD mechanism to communicate with AHI patients, this situation can perpetuate inaccuracies, fuel perceptions of inequity, and lessen trust in MHS providers.

Challenges Reported by Anomalous Health Incident Patients Accessing the Military Health System

DOD has created a plan to address some access concerns of AHI patients, but it contains uncertain timeframes and lacks monitoring provisions. For example, the plan produced a new approval process for AHI patients to enter the MHS and calls for an enhanced AHI Care Coordination Cell to centralize administrative and clinical processes. However, the timeframe for implementing the care cell has been delayed. Moreover, the plan does not contain components for monitoring these two key tasks, which could undercut its success.

DOD has developed a registry as required by law to include certain data on AHI patients assessed or treated by DOD. However, the AHI Registry data fields remain under development. Moreover, delays in obtaining individual consent for inclusion have limited the number of patients contained in the AHI Registry. DOD did not initially seek consent from individuals to be included in the registry when they entered the MHS, limiting the number of participants. Of 334 AHI patients who had qualified for care in the MHS in January 2024, only 33 had been entered in the AHI Registry as of May 2024. According to DOD, key agencies also have not signed memorandums of agreement with DOD, which has contributed to the slow inclusion of AHI patients. Without a plan to gather consent from AHI patients who have left the MHS, DOD will have a limited number of patients in the AHI Registry to analyze, which could limit its usefulness for supporting AHI analysis and research activities.

Why GAO Did This Study

In 2016, Department of State staff at the U.S. Embassy in Havana, Cuba, began experiencing a sudden onset of symptoms, usually following a loud sound. These included head pain, tinnitus, vision problems, vertigo, and cognitive difficulties. These events, first labeled “Havana Syndrome,” are now referred to as AHIs and have affected employees (and their families) of various federal agencies overseas and domestically. Federal law requires DOD to provide treatment to U.S. government employees (current and former) and their family members diagnosed with AHI conditions or related afflictions at an appropriate military treatment facility.

GAO was asked to review DOD's efforts to facilitate AHI patients' access to the MHS and develop an AHI Registry. This report examines (1) the challenges AHI patients have faced accessing care in the MHS, (2) how DOD is facilitating AHI patients' access to the MHS, and (3) the extent to which DOD has developed a registry to facilitate AHI research. GAO reviewed DOD planning documents and interviewed officials. GAO also interviewed, both in-person and virtually, 65 AHI patients from various federal entities on their experiences accessing the MHS.
