TB elimination was not achieved by any intervention scenario. The most aggressive strategy, 10-fold in all Californians, achieved a case rate of 8 (95% UI 4-16) per million by 2050. Of scenarios that reached pre-elimination, the incremental net cost was $20 billion (non-USB and MRF) to $48 billion. These had an incremental cost per QALY of $657,000 to $3.1 million. A more efficient but somewhat less effective single-lifetime test strategy reached as low as $80,000 per QALY.
Substantial gains can be made in TB control in coming years by scaling-up current testing and treatment in non-USB and those with medical risks.</description><identifier>ISSN: 1932-6203</identifier><identifier>EISSN: 1932-6203</identifier><identifier>DOI: 10.1371/journal.pone.0214532</identifier><identifier>PMID: 30964878</identifier><language>eng</language><publisher>United States: Public Library of Science</publisher><subject>Age ; Algorithms ; Antitubercular agents ; Antitubercular Agents - therapeutic use ; Biology and Life Sciences ; Calibration ; California - epidemiology ; Computer Simulation ; Consortia ; Cost-Benefit Analysis ; Costs ; Critical care ; Data buses ; Diagnosis ; Disease control ; Disease eradication ; Disease Eradication - methods ; Disease prevention ; Epidemics ; Epidemiology ; Fees & charges ; Gold ; Health ; Health care policy ; Health risks ; Hepatitis ; Historical metallurgy ; HIV ; Human immunodeficiency virus ; Humans ; Incidence ; Infections ; Inflammatory bowel disease ; Isoniazid ; Isoniazid - pharmacology ; Laboratories ; Mass Screening - economics ; Medical research ; Medicine ; Medicine and Health Sciences ; People and places ; Physical sciences ; Population ; Prevention ; Public health ; Quality-Adjusted Life Years ; Research and analysis methods ; Rheumatoid arthritis ; Rifampin - analogs & derivatives ; Rifampin - pharmacology ; Rifapentine ; Risk analysis ; Risk Factors ; Scaling ; Social Sciences ; Stochastic models ; Stochastic Processes ; Stochasticity ; Strategy ; Transplants & implants ; Tuberculin Test - economics ; Tuberculosis ; Tuberculosis - epidemiology ; Tuberculosis - prevention & control ; Tumor necrosis factor-TNF ; USB (Universal serial bus) ; World Health Organization</subject><ispartof>PloS one, 2019-04, Vol.14 (4), p.e0214532-e0214532</ispartof><rights>COPYRIGHT 2019 Public Library of Science</rights><rights>This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Pre-elimination was achieved by 2065 in three scenarios: a 10-fold increase in the non-USB and persons with MRF (by 2052), and 4- or 10-fold increase in all Californians (by 2058 and 2035, respectively). TB elimination was not achieved by any intervention scenario. The most aggressive strategy, 10-fold in all Californians, achieved a case rate of 8 (95% UI 4-16) per million by 2050. Of scenarios that reached pre-elimination, the incremental net cost was $20 billion (non-USB and MRF) to $48 billion. These had an incremental cost per QALY of $657,000 to $3.1 million. A more efficient but somewhat less effective single-lifetime test strategy reached as low as $80,000 per QALY.
Substantial gains can be made in TB control in coming years by scaling-up current testing and treatment in non-USB and those with medical risks.</abstract><cop>United States</cop><pub>Public Library of Science</pub><pmid>30964878</pmid><doi>10.1371/journal.pone.0214532</doi><tpages>e0214532</tpages><orcidid>https://orcid.org/0000-0002-2324-5858</orcidid><oa>free_for_read</oa></addata></record> |
