Journal Club: Changing therapeutic geographies

We had a very different sort of research paper in journal club three weeks ago, and I was too busy to jot it down until now. Dewachi et al, Changing therapeutic geographies of the Iraqi and Syrian wars. This is certainly not our usual metrics-heavy approach, so it was good exercise to try to understand it.

Journal Club: Repeat Bone Mineral Density Screening and Prediction of Hip and Major Osteoporotic Fracture

Last week we read Repeat Bone Mineral Density Screening and Prediction of Hip and Major Osteoporotic Fracture by Berry et al. It argues that repeat screening does not improve predictions. But I think the world needs a better way to measure the quality of predictions like these. Area-under-the-curve doesn’t cut it when you are predicting the unpredictable.

Journal Club: Racial Discrimination & Cardiovascular Disease Risk

Tomorrow is journal club, starting up again for the winter quarter. We are reading Racial Discrimination & Cardiovascular Disease Risk: My Body My Story Study of 1005 US-Born Black and White Community Health Center Participants (US) by Krieger et al.

One exposure paper uses is measured with the Implicit Association Test, which I was trying to explain and couldn’t remember the details of. So I checked online, and learned you can take one yourself! It takes about ten minutes, and may reveal surprising things about you: https://implicit.harvard.edu/implicit/takeatest.html

Journal Club: Meat, fish, and esophageal cancer risk: a systematic review and dose-response meta-analysis

For our final journal club paper of last semester, we read Meat, fish, and esophageal cancer risk: a systematic review and dose-response meta-analysis. I am a vegetarian.

That brings me up to date for fall quarter, and the winter quarter is just finishing its first week. Good!

Journal Club: Investigating health system performance: An application of data envelopment analysis to Zambian hospitals

I’m almost caught up on recording last quarter’s journal club papers, with this second to last topic: Investigating health system performance: An application of data envelopment analysis to Zambian hospitals by Felix Masiye.

This data envelopment analysis (DEA) is an approach I’ve been hearing a lot about recently, and it seems to work through quite an operations-research lens. I hope I’ll be looking into it more in the near future.

Journal Club: Wireless Substitution: State-level Estimates From the National Health Interview Survey, January 2007–June 2010

This National Health Statistics Report that we read toward the end of last quarter’s journal club has one of the driest names we’ve seen. But the topic is a fascinating glimpse into the limits of our knowledge about society. How many households in USA have given up their landline phone entirely and only have a cell phone? Well, we answer most questions like that with a telephone survey. Uh-oh. Fortunately the National Health Interview Survey (in my experience, pronounced most commonly as “en-hiss”) is a health survey were enumerators visit households in person, and even though it is about population health, it can also answer this pressing question about technology use (and the potential invalidity of all of the surveys that do not visit households in person, but just call on the phone).

Journal Club: Parental income and health inequality

Continuing to catch up on my record of journal club topics, just under a month ago we read Parental income and the dynamics of health inequality in early childhood–evidence from the UK. There was a discussion of whether this was typical for a health economics paper.

Journal Club: Prognosis of patients with HIV-1 infection

Oh, how the quarter gets away. What happened in our journal club since I last recorded a paper? Well, I will start catching up now. The first thing that happened was just over a month ago we read a paper on prognosis for lovers of survival curves: Prognosis of patients with HIV-1 infection starting antiretroviral therapy in sub-Saharan Africa: a collaborative analysis of scale-up programmes. The author’s interpretation of their results:

INTERPRETATION:
Prognostic models should be used to counsel patients, plan health services, and predict outcomes for patients with HIV-1 infection in sub-Saharan Africa.

Journal Club: Assessment of statistical models

This week in journal club, we will be reading Green et al, Use of posterior predictive assessments to evaluate model fit in multilevel logistic regression. I like posterior predictive checks, here are some of the stats papers that we might read in the future if my students do, too:
