TED: The big-data revolution in health care | Joel Selanikio

The video discusses the challenges of data collection in global health, highlighting the inefficiencies of paper-based methods. It introduces the concept of using digital tools like PalmPilots and later cloud-based software, Magpi, to streamline data collection and analysis. The speaker emphasizes the need for scalable solutions that do not rely on individual consultants, drawing inspiration from the self-service model of cloud services like Hotmail. The impact of these innovations is illustrated through various global applications, demonstrating significant improvements in efficiency and data accessibility.

What is the main challenge associated with 'big data' as mentioned in the introduction?

• Lack of data on the internet

• High cost of data storage

• Limited access to data

• Organizing the vast amount of information

Why is paper-based data collection considered inefficient in global health?

• It is too expensive

• It leads to delays and errors

• It requires advanced technology

• It is not accepted by health organizations

What was the initial digital solution proposed to improve data collection?

• Using tablets

• Using laptops

• Using PalmPilots

• Using smartphones

What was identified as the main obstacle in scaling the initial digital solution?

• Resistance from health workers

• Technical difficulties

• Dependence on a single individual

• Lack of funding

What inspired the development of cloud-based solutions like Magpi?

• The success of PalmPilots

• The popularity of Hotmail

• The need for more consultants

• The rise of social media

How did the development of Magpi change the approach to data collection?

• It allowed users to create forms without training

• It made data collection more expensive

• It limited data collection to smartphones

• It required more consultants

What is one of the benefits of using cloud-based data collection systems?

• They are only available in developed countries

• They provide instant data analysis

• They are more expensive than traditional methods

• They require extensive training

How did the use of Magpi impact the International Rescue Committee's work?

• It limited data collection to urban areas

• It increased the cost of data collection

• It provided real-time data on births and deaths

• It required more staff for data entry

What was the cost comparison between traditional consultation and using Magpi for Camfed?

• Both had similar costs

• Magpi was significantly cheaper

• Traditional consultation was cheaper

• Magpi was more expensive

What is the overall impact of digital data collection on global health?

• It has increased the need for paper forms

• It has limited data collection to specific regions

• It has made data collection more complex

• It has improved efficiency and saved lives
