Introduction Noncommunicable diseases (NCD) (cardiovascular disease, cancer, diabetes, and chronic respiratory diseases) are leading causes of deaths and disabilities worldwide. NCD accounts for 63% of global deaths (37 million annually), with 80% occurring in low and middle income countries. Almost a third of deaths from NCD in poor countries occurred prematurely in population under 60 years old. Monitoring the progress that countries are making with reducing the burden of NCD is a key function of the Public Health Surveillance for NCDs prevention and control. 2
Challenge Assessing and monitoring the level and trends of premature mortality from NCDs requires several large and heterogeneous data sources: 1. Registered death data (Vital Statistics) from death certificates reported by national authorities (official data) from 48 countries of the Americas 2. Population estimates by country, year, sex and age groups 3. Other reference data (e.g. world standard population, catalogue of causes of deaths, country, sex, and age groups).

Title of the Presentation
Conclusions • In the past, data were prepared using Excel and coding SQL sentences in MS Management Studio. • A lot of time expended with this approach, less control and transparency • Data preparation and integration using Alteryx allows us to improve: o The efficiency of processes. 60% reduction of data prep time o Transparency and gain more control over the data prep processes o Reutilization and automation of processes o Documentation of data preparation processes 12
