To treat a cluster of tuberculosis (TB) transmission cases in a long-term care facility for cognitively impaired adults located in Puerto Rico (facility A), the Puerto Rico TB Control Program used a novel video directly observed therapy (VDOT) application. In 2016, active TB disease was diagnosed in 11 residents and latent TB infection (LTBI) was diagnosed in six residents of facility A. Asynchronous VDOT was used to monitor treatment for these 17 residents. One of the patients with active TB disease had received a diagnosis of LTBI during an investigation at facility A during 2011–2012. During 2010–2012, seven residents of facility A received a diagnosis of active TB disease; four of these diagnoses were culture-confirmed, with isolates that had the same rare genotype (1). Drug susceptibility testing indicated sensitivity to the standard first-line regimen of rifampin, isoniazid, pyrazinamide, and ethambutol (RIPE). Three of the seven TB patients died before starting treatment; the other four were prescribed the RIPE regimen under the supervision of personnel from facility A. Two of the four patients who reportedly completed RIPE treatment in 2012 died in 2016 from unrecognized TB-related conditions; both patients were roommates of the 2016 index case patient. For these two patients, evidence of TB discovered during a postmortem medical record review included ineffective antibiotic treatments for putative community-acquired pneumonia and bronchitis and signs of wasting, which were corroborated by interviews with staff members and treating physician. No patients at facility A tested positive for human immunodeficiency virus infection in 2012 or 2016. The contact investigation performed in 2011–2012 identified LTBI in 26 residents and seven nonresidents. All contacts with LTBI were reported by facility staff members as having completed treatment with 4 months of daily rifampin (4R), one of a few standard LTBI regimens, in 2012. On June 20, 2016, a resident of facility A, who was a contact from the 2011–2012 investigation and whose facility records indicated prior treatment for LTBI with 4R, was identified as having advanced cavitary TB disease; the genotype and drug susceptibility testing of this patient’s isolate matched that of the original cases. This resident began treatment with a 6-month course of RIPE; ethambutol was discontinued after drug sensitivities were confirmed. Among 38 residents and 15 staff members, 10 additional cases of active TB disease were diagnosed among residents; these patients were prescribed rifampin, isoniazid, and pyrazinamide (without ethambutol). Six other residents with diagnosed LTBI were prescribed 4R treatment. Because of staffing shortages, Puerto Rico Department of Health (PRDH) TB field personnel were not available to administer daily directly observed therapy (DOT) at facility A and facility A did not have the personnel needed to provide daily patient transport to the PRDH clinic. VDOT uses video and computer equipment that allows public health officials to observe patients taking medications for TB, and it has been successfully used to ensure proper completion of TB treatment (2–5). A standard live VDOT protocol (e.g., using FaceTime) (4) was attempted at facility A but was not sustainable because cell phones or Internet connectivity were not consistently available. An asynchronous VDOT protocol that did not require real-time Internet connection or a cellular plan, complied with the Health Insurance Portability and Accountability Act, and provided a Spanish external-facing application*,† was implemented to ensure proper treatment for TB and LTBI patients. Use of this asynchronous system avoided audio/visual interruption related to poor connectivity, which can be problematic in standard live VDOT applications (4), by capturing and storing videos of patients as they swallowed their TB medications, and automatically uploading the videos after Internet connection became available. Videos were viewed by PRDH staff members at 2–10 times the speed at which they were recorded. In addition to the clinic-to-facility commute, which would have taken 1.5 hours per day, DOT for the 17 severely cognitively challenged men would have required an additional 1.5 hours per day of observation. Use of asynchronous VDOT saved PRDH approximately 240 hours in DOT-related activities, equivalent to 25% of the workload for a full-time epidemiology technician/case manager over 6 months of treatment. As of July 12, 2017, all 11 patients with active TB disease and all six with LTBI had completed treatment with recommended ≥80% compliance (percentage of scheduled doses actually taken) (Table) (6). Active TB disease treatment rates were higher than those for LTBI because protocols exist for
