Released today. Some of the highlights
During 2005, an estimated 115.3 million visits were made to hospital EDs, about 39.6 visits per 100 persons. This represents on average roughly 30,000 visits per ED in 2005, a 31 percent increase over 1995 (23,000). Visit rates have shown an increasing trend since 1995 for persons 22–49 years of age, 50–64 years of age, and 65 years of age and over. In 2005, about 0.5 million (0.4 percent) of visits were made by homeless individuals. Nearly 18 million patients arrived by ambulance (15.5 percent). At 1.9 percent of visits, the patient had been discharged from the hospital within the previous 7 days. Abdominal pain, chest pain, fever, and cough were the leading patient complaints, accounting for nearly one-fifth of all visits. Abdominal pain was the leading illness-related diagnosis at ED visits. There were an estimated 41.9 million injury-related visits or 14.4 visits per 100 persons.

The Centers for Disease Control and Prevention today issued a new report, “Ambulatory Medical Care Utilization Estimates for 2005,” which contains information on patient visits to emergency departments, outpatient clinics, and physician offices.
Highlights of the report:
There were over 1.2 billion patient visits to physician offices, hospital outpatient clinics, and emergency rooms in 2005. Over the past decade, rates of visits per population increased for all types of health care settings studied.
In the emergency department, the visit rate for patients with no insurance was about twice that of those with private insurance.
Conversely, patient visits to physician offices were higher for individuals with private health insurance compared with uninsured persons.
Over 29 percent of all ambulatory care visits were for chronic diseases such as heart disease and diabetes, and one in four were for preventive care, including check-ups, prenatal care, and post-surgical care.
There were 2.4 billion medications prescribed or administered at these visits.

We had a question about the number of persons in the United States who die from HIV/AIDS.
Mortality data indicate that in 2004 5,608 whites (rate of 2.4 per 100,000), 7271 blacks (18.8 per 100,000), and 184 persons of other races (rate of 1.1 per 100,000) died of HIV/AIDS.
You can do your own analysis by year at CDC’s public access WONDER database (select ICD 10 codes B20-B24 in section 4) or you can quickly determine where HIV/AIDS ranks in the CDC’s WISQARS Leading Cause of Death Report.

According to the Centers for Disease Control and Prevention publication Morbidity and Mortality Weekly Report:
Chronic kidney disease (CKD) is a serious condition associated with premature mortality, decreased quality of life, and increased health-care expenditures. Untreated CKD can result in end-stage renal disease and necessitate dialysis or kidney transplantation. Risk factors for CKD include cardiovascular disease, diabetes, hypertension, and obesity (1–3). To estimate the prevalence of CKD in the United States (overall and by health risk factors and other characteristics), CDC analyzed the most recent data from the National Health and Nutrition Examination Survey (NHANES).
About 16.8% of the US population aged 20 and older suffer from this condition. Among adults with diabetes that number is 40.2%.

Yesterday the Journal of the American Medical Association published an article entitled Incidence of Diabetes in Youth in the United States. From the JAMA press release:
Non-Hispanic white youth have the highest rate of diabetes of all racial/ethnic groups for children in the U.S., with type 1 being the predominant kind of diabetes among youth, according to a study in the June 27 issue of JAMA, a theme issue on chronic diseases of children.
For children age 0 to 4 years and 5 to 9 years, most DM was type 1, regardless of race/ethnicity. The incidence of type 1 DM was highest among non-Hispanic white children, and lowest among American Indian and Asian-Pacific Islander children. Similarly, for older youth (10-14 years and 15-19 years), the incidence of type 1 DM was highest among non-Hispanic white children, followed by African American and Hispanic youth.
“…taken together [with other studies], these data suggest that the incidence of type 1 DM may be increasing in the United States, consistent with worldwide trends,” the authors write. “We estimate that the annual number of newly diagnosed youth with type 1 DM in the United States is approximately 15,000.”

The sad case of the murder of 26 year old Jessie Davis has gained national media attention.
Though the National Center for Health Statistics tracks deaths, and as a subset of that homicides, the feeder document for the National Vital Statistics System, in this case the death certificate, does not allow us to identify the number of persons murdered by intimate partners.
Our parent agency, the Centers for Disease Control and Prevention, has done some research into the subject. In March 2005, three researchers, Jeani Chang, Cynthia J. Berg, and Joy Herndon from the Division of Reproductive Health, National Center for Chronic Disease Prevention and Health Promotion, published a paper in the American Journal of Public Health entitled Homicide: A Leading Cause of Injury Deaths Among Pregnant and Postpartum Women in the United States, 1991–1999. This paper was reported on by the Washington Post.Currently the National Center for Injury Prevention and Control has a fact sheet with summarizes current research on the subject.
