UPDATE: Flint map randomization

See all emails with these participants
>; Stanbury, Martha (DHHS) <stanburym@rnichiganeov> Martha and Bob, Attached is a new rnap of EBLL cases in Flint randomized by a method used by Ed Hartwick. It’s better than the previous man | generated where cases were scattered at randarn throughout the city. in the revised mas, cases were shifted slightly fram their original point so some of the clustering stl holes up. This is probably the final map that GCHD could use for their presentation. Let me know if you have any questions or if you want to discuss. Thank you, Junaid

Flint map with randomized points

See all emails with these participants
EBSD BOv> Martha and Bob, Attached is the map of Flint with points randomized by zip code, meaning | calculated the # of cases with BLL between 5 and 9 ug/dL (inclusive) and with BLL 210 ug/dL for each zip code and plotted the same number of cases per zip code in random locations within the zip code boundary. Unfortunately, as we originally suspected, the clustering of cases depicted in the original map (also attached) is lost with this randomization. Junaid xxxEND_PAGE:dhhs03_b0797_2896_2897_2

RE: Tom Talbot's Geographic Masking Tool

Thanks Tom. What you're saying makes a lot of sense. From the map, it seerns like GCHD wants to highlight the nurnber of cases with BLL between 5 and 9 ug/di {inclusive} and thase with BLL 10 ug/di or greater. This would be difficult to portray ina single choronleth map. i'm not entirely sure what message GCHD warts to get across with the map but two chorapleth rnaps would be a shripler solution to randomizing the points across the city af Flint.

This portion of what’s written under “Geographic Aggregation Tool” - join neighboring geographic areas together until a user defined population and/or number of cases is reached — is what | was getting at during our meeting this morning. That is, you expand a geographic area until a certain minimal number of cases are contained, then indicate the number of cases within that section (or have a variety of ranges of cases and create a choropleth map).

>; pen Thomas W. (DHHS) <i, i ‘>; Stanbury, Martha xxxEND_PAGE:dhhs03_b0472_1717_1718_1 001718 Hi Junaid, | can’t locate my copy of Tom’s tools that he handed out at CSTE a few years back, but they are described at his web page under “Geographic Aggregation and Masking Tools” . | was thinking the GAT would be useful for the lead data, and it looks like there is both R and SAS code. Hope this is helpful. Lorri PS if you can’t download them from his website | bet they are in the Tracking website. xxxEND_PAGE:dhhs03_b0472_1717_1718_2

Status of Child EBL Services Database

See all emails with these participants
Oy. Hi All, Here are the next tasks on our DEH Flint Coordination Team (Martha named us!}) collaboration to create the Child EBL Services Database: 1. Hotlink to the draft data dictionary £:\£84 fnvestigat a. Bobis checking and adding nurse case management variables (CM). (DONE) b. Need to check EBL Investigation (El) variables. (Ask Courtney) c. Need to finalize the data dictionary (Review by Junaid) 2. Need to determine the common variable ID between the CM and El spreadsheets a. Based ona discussed between Martha and | — the suggestion is using the HUD EBL ID for a home. 3. Need a list of questions that we want to be able to answer with this database. a. Kory will talk with Linda, Wes, Courtney (already talked with Martha) about the questions they want to be able to answer with this database. Kory will compile the questions and send around for review. c. Compare the questions to the variables in the data dictionary and consider if we have the correct variables to answer our questions. (TO BE DETERMINED — how and who is best to do that — may be a group effort) 4. Once all variable are entered in the data dictionary and Junaid says the dictionary is done, then he start working on Access Database. Thank you for your attention.

RE: EPHT Childhood Lead Poisoning algorithm

xxxEND_PAGE:dhhs02_b0517_1995_1997_2 001997 We are using the highest test and following AAP guidelines as this has clinical irnplications. Yan and |reviewed outout and modified our plan. We are using specimen date and not report date, which means the tables will be dynamic. When we used report date to define the cohort we found some records with specimen dates fram as far back as 2012 and 2013, the mean and sd were astronomical, which is another quality improvement analysis for a later time. Only 22 records reported on 10-30-14 were fram the week ending 10/30/14. Interestingly all 22 records were <5 meg/dl. Ry changing te specimen date to select the cohort ,we find mean interval between specimen and report is 12.4 days, so we are examining other reporting intervals such that we have sufficient n, and feel that we have most of the tests. Also the latest record that we found for the week reported 10/30 was on 10/27, will need to comrnunicate some of the fags in reporting. We have table shells, we have the datasets created to do what we need te do, and are new analyzing the data te determine the suitable reporting interval. Then we will fill the tables and review everything. I'm working on a ‘technical specs’ to explain what we did. anticipate that we will have something for the group te look at later this week, hopefully within a day or two, if all goes as planned.
