, unlike the other databases we use, includes a variable indicating whether the admission was "Elective," "Urgent," or an "Emergency.
We used the 2000 Census of Population and Housing to obtain more age specificity, and then corrected the 2000 Census figures so that the total population equaled the total for 1999 forecasted by NHDS
A similar trio of indexes produced from NHDS
data is presented in the second panel of chart 1.
For 1995, NHDS
estimates less than 5000 generally have a relative standard error of more than 30% or are based on a sample of fewer than 30 cases.
During 2000-2006, mean annual rates of hospitalization for acute gastroenteritis were 203 hospitalizations per 100,000 persons according to NHDS
data, 187 per 100,000 according to NIS data, and 109 per 100,000 according to NAMCS and NHAMCS data.
Moreover, the NHDS
data comprise hospital inpatient codes, which are unlikely to include a diagnosis of metabolic syndrome (Diabetes Care 2005;28:1831-2).
In the NHDS
, data were collected from a sample of inpatient records acquired from a national probability sample of non-Federal short-stay hospitals.
Characteristics of CDI-related and nonrelated hospitalizations in the NHDS
are shown in Table 2.
Estimates from the NHDS
were obtained for 1996 (NCHS 2004d).
Coronary Arteriography and Coronary Bypass Survey among Caucasians and Other Racial Groups Relative to Hospital-based Incidence Rates for Coronary Artery Disease: Findings from NHDS
For 1993-94, discharge rates from the NHDS
for injury among persons under age 25 were 737 per 100,000 for males, 414 per 100,000 for females, and 576 per 100,000 for all persons in this age group (U.
covers [approximately equal to] 270,000 patients and 500 short-stay hospitals by using a stratified, multistage survey to create a nationally representative annual sample of discharge records.
