Weekly links April 3: scaling up in perspective, surveying with mobile apps, and more…

This page in:
  • Pew research on “what we learned about surveying with mobile apps”: “Immediate responses and feedback can be helpful and revealing” but “App response rates were lower than Web rates overall and for each of the 14 surveys we conducted”
  • Freakonomics asks “How do we know what really works in healthcare?” – a podcast about RCTs. I like this comment from a doctor about scaling up “I think Medicare’s comment was that it’s really hard to do. We’re not sure we could scale it. Well, we f***ing scaled open heart surgery. We scaled separating Siamese twins. We scaled transplanting hearts and lungs, curing complex cancers. We’re sequencing the human genome. You’re telling me we can’t have a nurse go out and check on your mom or grandmother in a highly organized, well-structured, well-trained intervention for which someone’s already doing it for hundreds and hundreds of patients every day?”
