Objectives: In the past decade, there has been a growing interest in health technology disinvestment. A disinvestment process should involve all relevant stakeholders to identify and deliver the most effective, safe, and cost-effective healthcare interventions. The aim of the present study was to describe the state of the art of health technology disinvestment around the world and to identify parameters that could be associated with the implementation of disinvestment programs.

Methods: A systematic review of the literature was performed from database inception to November 2014, together with the collection of original data on socio-economic indicators from forty countries.

Results: Overall, 1,456 records (1,199 from electronic databases and 257 from other sources) were initially retrieved. After analyzing 172 full text articles, 38 papers describing fifteen disinvestment programs/experiences in eight countries were included. The majority (12/15) of disinvestment programs began after 2006. As expected, these programs were more common in developed countries, 63 percent of which had a Beveridge model healthcare system. The univariate analysis showed that countries with disinvestment programs had a significantly higher level of Human Development Index, Gross Domestic Product per capita, public expenditure on health and social services, life expectancy at birth and a lower level of infant mortality rate, and of perceived corruption. The existence of HTA agencies in the country was a strong predictor (p = .034) for the development of disinvestment programs.

Conclusions: The most significant variables in the univariate analysis were connected by a common factor, potentially related to the overall development stage of the country.

Objectives: The aim of this study was to identify and rank the sources for the detection of potentially obsolete technologies (POTs).

Methods: A specific questionnaire related to the search strategies and sources used for the identification of POTs and also for ineffective, inefficient or harmful health technologies was sent to the Health Technology Assessment International's Information Resources Group (HTAi-IRG) group. With the obtained information and taking into account the sources used for the identification of new and emerging technologies, a second questionnaire was elaborated and sent to EuroScan and International Network of Agencies for Health Technology Assessment (INAHTA) members, who had to select and score them. For the final ranking, the number of votes and the median score were taken into account.

Results: Seven HTAi-IRG members answered to the first questionnaire. Seventeen agencies answered to the second one (thirteen EuroScan members and four more members from INAHTA), but only seven had worked in the identification of POTs and one of them using only experts for it. The remaining six agencies answered the part related to devices, diagnostics, and procedures; five of them did it for settings and programmes and only three for drugs. The Canadian Agency for Drugs and Technologies in Health (5 votes; median = 2), Cochrane Collaboration (5 votes; median = 3), NICE (4 votes; median = 1), Food and Drug Administration (4 votes; median = 1.5), and EuroScan (4 votes, median = 2) were the most relevant sources for devices and diagnostics.

Conclusions: There is little experience on POTs identification. The identified sources provide mostly indirect information and further research should take place to determine the best use of them.
