Sampling Procedures for the Collection of Electronic Health Record Data From Federally Qualified Health Centers, 2021-2022 National Ambulatory Medical Care Survey.

As part of modernization efforts, in 2021 the National Ambulatory Medical Care Survey (NAMCS) began collecting electronic health records (EHRs) for ambulatory care visits in its Health Center (HC) Component. As a result, the National Center for Health Statistics (NCHS)needed to adjust the approaches used in the sampling design for the HC Component. This report provides details on these changes to the 2021-2022 NAMCS.

National Hospital Care Survey Demonstration Projects: Severe Maternal Morbidity in Inpatient and Emergency Departments.

Objective-This report demonstrates the ability of the National Hospital Care Survey (NHCS) to examine delivery hospitalizations involving severe maternal morbidity (SMM). These data are unweighted and not nationally representative, so the results are intended to illustrate the unique capability of NHCS to track patients across hospitalizations and emergency department (ED) visits rather than provide nationally representative estimates of these outcomes.

Hospitalization for Total Knee Replacement Among Inpatients Aged 45 and Over: United States, 2000-2010.

In 2010, total knee replacement was the most frequently performed inpatient procedure on adults aged 45 and over. In the 11-year period from 2000 through 2010, an estimated 5.2 million total knee replacements were performed. Adults aged 45 and over comprised 98.1% of those surgeries. This report uses data from the National Hospital Discharge Survey (NHDS) to present trends in the rate of hospitalizations for total knee replacement, mean age at hospitalization, and discharge status for inpatients aged 45 and over from 2000 through 2010.

Inpatient care for septicemia or sepsis: a challenge for patients and hospitals.

Septicemia and sepsis are serious bloodstream infections that can rapidly become life-threatening. They arise from various infections, including those of the skin, lungs, abdomen, and urinary tract. Patients with these conditions are often treated in a hospital's intensive care unit. Early aggressive treatment increases the chance of survival. In 2008, an estimated $14.6 billion was spent on hospitalizations for septicemia, and from 1997 through 2008, the inflation-adjusted aggregate costs for treating patients hospitalized for this condition increased on average annually by 11.9%. Despite high treatment expenditures, septicemia and sepsis are often fatal. Those who survive severe sepsis are more likely to have permanent organ damage, cognitive impairment, and physical disability. Septicemia is a leading cause of death. The purpose of this report is to describe the most recent trends in care for hospital inpatients with these diagnoses.

National Hospital Discharge Survey: 2007 summary.

OBJECTIVES: This report presents national estimates of hospital inpatient care in the United States during 2007 and selected trend data. Numbers and rates of discharges, diagnoses, and procedures are shown by age and sex. Average lengths of stay are presented for all discharges and for selected diagnostic categories by age and by sex. METHODS: The estimates are based on data collected through the 2007 National Hospital Discharge Survey, an annual national probability sample survey of discharges from nonfederal, general, and short-stay hospitals. Sample data are weighted to produce annual estimates of inpatient care, excluding newborns. Diagnoses and procedures are coded using the International Classification of Diseases, Ninth Revision, Clinical Modification. RESULTS: In 2007, there were an estimated 34.4 million hospital discharges, excluding newborns. The total hospitalization rate leveled off from 1995 to 2007 after declining during the period from 1980 to 1995. Throughout the period from 1970 to 2007 the rates for those aged 65 years and over were significantly higher than the rates for the younger groups. Although those aged 65 years and over accounted for only 13 percent of the total population, they comprised 37 percent of hospital discharges and 43 percent of hospital days. One-quarter of inpatients under age 15 years were hospitalized for respiratory diseases. There were 45 million inpatient procedures during 2007 and 15 percent of these were cardiovascular. Males aged 45-64 and 65 years and over had higher cardiac catheterization rates than females in these age groups each year from 1997 to 2007. From 2002 to 2007 the rate of inpatient cardiac catheterization procedures declined.
