Health Insurance Coverage To provide a complete picture of the uninsured population, the National Health Interview Survey (NHIS) tracks: persons who currently lack coverage; persons uninsured at any time in the previous year; persons who have experienced lack of coverage for more than a year. Health care surveys also report health insurance measures, such as the National Ambulatory Care Survey (NAMCS), which reports expected source of payment from doctor visits.

Health Insurance Coverage: From the NHIS—Lack of Coverage Data are released from NHIS  In ASCII (raw data files)  On the Internet, as an Early Release  In publications (forthcoming)  In Data2010, as a Healthy People 2010 Objective  In a customizable table on the Health Data for All Ages site (update to 2004 forthcoming)  Other sources, such as Health, United States, FASTSTATS etc…

Prescription Drug Use Prescription drug use is in the rise in America… In , 45 percent of Americans used a prescription drug in the last month, while 18 percent used three or more; and use among seniors is much higher.

NCHS Statistics on Prescription Drugs To find out more about drug use in America, we will use the following data tools: National Survey of Children’s Health Data Resource Tool to find statistics on children’s use of prescription drugs Trends in Health and Aging to find statistics on the distribution of drug mentions in doctor offices Ambulatory Care Drug Database System to find the number of drug mentions for a specific drug WISCARS to find the number of drug-related adverse effect deaths

Cesarean Delivery Statistics: Healthy People Objectives, Health Data for All Ages, and SETS Lowering the cesarean rate in the United States has been a goal for the past 25 years. Separate objectives were formulated for low-risk women giving birth for the first time (a subset of all women having a first birth) and for low- risk women who had a prior cesarean birth. The objectives set a target of 15 percent for cesarean delivery and 63 percent for repeat cesarean delivery. From: National Vital Statistics Reports, Vol. 54, No. 4, September 22, 2005, Table 1. Cesarean rates for first births to low- risk women by age and race and Hispanic origin of mother: United States… page 6.

Healthy People Objectives-- Cesarean Delivery Step 1: Type in “cesarean” in the keyword box and the button. The Healthy People Objectives with the word “cesarean” will appear in the objective box below. In this case, there were two objectives with cesarean: Objective 16-09a and 16-09b.

Healthy People Objectives-- Cesarean Delivery Step 2: Choose the Submit button and the 16-09a table with the base line year and percent, the data years and the 2010 target will appear.

Health Data for All Ages produces a table on cesarean rates for low-risk women

Customizing the Cesarean Deliveries Table for To Show Only Prior Cesarean Deliveries Step 1: Click on the Cesarean cell. Step 2: Deselect the default selections by choosing the button. Select “Prior Cesarean” from the list. Choose the table button and the table will only show prior cesarean deliveries.

Customizing for Specific Locations Step 3: To further customize the table, I would only like to look at Maryland, Washington DC, and Virginia. To do this, you need to select Location, deselect the defaults, and check the appropriate boxes for the locations I want to view. Select the table icon again to view your selections.

Looking at Race and Ethnicity Step 4: To look at specific race and ethnicity, we want to further customize our table view. To do this, we need to physically drag and drop the Race/Ethnicity cell into the Cesarean cell. (The Cesarean cell the moves to the old position). Move the cells so the order is Maternal Age, Race/Ethnicity, Location.

Using SETS to Create a Cesarean Delivery Table To match estimates published in our reports, such as the Trends in Cesarean Rates for First Births and Repeat Cesarean Rates for Low-Risk Women: United States, Trends in Cesarean Rates for First Births and Repeat Cesarean Rates for Low-Risk Women: United States, From: National Vital Statistics Reports, Vol. 54, No. 4, September 22, 2005, Table 1. Cesarean rates for first births to low- risk women by age and race and Hispanic origin of mother: United States… page 6.

Using SETS to Create a Cesarean Delivery Table—Getting Started Step 2: Choose the correct drive, and the NCHS folder. Step 3: Choose the Nata2003 file. Step 4: Accept the usage requirements. Step 1: Open the SETS folder and the SETS Interface.

Using SETS to Create a Cesarean Delivery Table—Getting Started Step 3: From the menu, go to Table and Assist. Step 2: Choose the 2003 Natality File in the Data Folder…and Tabulate data. Step 1: Go to file, and select Open, and Set.

Using SETS to Create a Cesarean Delivery Table– Selecting only U.S. Born Residents 1. Go to Records and the choose Select. Click Assist. 2. Double click on the empty Field box. Add choose 4. Choose RESTATUS (Resident Status) from the list and Select. Choose the =! Operator from the pull down list and double click on the Code box and choose 4 (FOREIGN RESIDENTS). 3.

Using SETS to Create a Cesarean Delivery Table– Selecting only Low Risk Pregnancies full-term pregnancy (at least 37 completed weeks of gestation RGEST3=, or “37 Weeks and over”), singleton pregnancy (not a multiple pregnancy ), safe fetal presentation (head in a downward position in the birth canal). 6. To look at only low risk pregnancy, we need to select the our records: Please note: RESTATUS =! 4 was selected previously. We also need to select “Detailed Total Birth Order” or RTBO = 01 (first birth) to recreate the Table 1 in the report, which only includes first births. 7. Accept the record selection and choose Select, when prompted.

Using SETS to Create a Cesarean Delivery Table- Recoding a Field To create the age groups used in the table, we need to create a recode in SETS. To do this: 1.Go to Recodes and Create. 2.Type in the file name of your recode and save to your hard drive (c) and go to Recode and Assist. 3.Double click on the Based on field box, and 4.Type in age and choose OK.

Type in an optional category label, such as, “Under age 20 years.” 3.Double click on the second code box and choose code Continue this process until you’ve created 6 categories to match the ones in the publication.

Using SETS to Create a Cesarean Delivery Table- Creating a Recode 5.Go to Recodes and select Attach. 6. Your age recode will now show up in the fields and recodes list.

Using SETS to Create a Cesarean Delivery Table Step 1: Go to Table and Assist. This brings up the Table Assistance template. Step 2: Select your age recode and the RDELMTH field by highlighting it and selecting the Add button. So they appear in the Table fields box to the right.

Using SETS to Create a Cesarean Delivery Table Step 3. Go to the Nesting options table (2), leave the defaults and go to table 3, Generate Statements. Step 4. Choose the Generate button and go to the Begin tabulation table (4). Select the Begin button.
