RESUMEN
OBJECTIVES: To introduce the Laboratory Quality Stepwise Implementation (LQSI) tool and provide data about its roll-out, usage and effectiveness in assisting laboratories with quality improvement. METHODS: The LQSI tool, a freely available stepwise guide, was developed by WHO to assist laboratories with efficiently implementing a quality management system. RESULTS: Since the tool's launch in 2014, it has been accessed by 130 986 unique users from 195 of 206 listed states. Of 35 respondents to a survey, 12 (34%) indicated that their laboratory had been able to achieve accreditation/certification/licensing as a result of using the tool. CONCLUSIONS: The LQSI tool, currently being used worldwide and available in English, French, Russian, Spanish, Arabic and Turkish, positively impacts the quality of services provided by clinical and public health laboratories, leading to improved clinical care and disease surveillance capacity as required by the IHR (2005) and envisioned by the Global Health Security Agenda.
