Vital and health statistics. Series 13, Data from the National Health Survey最新文献

Objective: The 1995 National Nursing Home Survey (NNHS) was conducted to collect data on nursing homes and their current residents. This report presents detailed data on the characteristics of the nursing homes including ownership, certification, bed size, location, affiliation, and services provided. Data on current residents are presented by basic demographics, living arrangement prior to admission, functional status, and other health and personal characteristics of the residents.

Methods: The 1995 NNHS is a sample survey consisting of a two-stage design with a probability sample of 1,500 nursing facilities in the first stage and up to six current residents from each facility in the second stage.

Results: About 1.5 million residents were receiving care in an estimated 16,700 nursing homes in 1995. Nearly 1.8 million beds were available and facilities operated at about 87 percent of their capacity. Nearly 90 percent of the residents were 65 years and over. They were predominantly female and white with a large portion needing assistance in the activities of daily living (ADL's) and instrumental activities of daily living (IADL's).

Objectives: This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 1997. Estimates of first-listed diagnoses, all-listed diagnoses, days of care for first-listed diagnoses, and all-listed procedures are shown by sex and age of patient and geographic region of hospital.

Methods: The estimates are based on data collected through the National Hospital Discharge Survey for 1997. The survey has been conducted annually by the National Center for Health Statistics since 1965. In 1997 data were collected for approximately 300,000 discharges from 474 non-Federal short-stay hospitals. Diagnoses and procedures are presented according to their code number in the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM).

Objectives: This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 1997 and selected trend data. Estimates are provided by demographic characteristics of patients discharged, geographic region of hospitals, conditions diagnosed, and surgical and nonsurgical procedures performed. Measurements of hospital use include number and rate of discharges and days of care, and the average length of stay.

Methods: The estimates are based on data collected through the National Hospital Discharge Survey. The survey has been conducted annually by the National Center for Health Statistics since 1965. In 1997, data were collected for approximately 300,000 discharges. Of the 501 eligible non-Federal short-stay hospitals in the sample, 474 (95 percent) responded to the survey. Diagnoses and procedures were coded according to the International Classification of Diseases, 9th Revision, Clinical Modification, or ICD-9-CM.

Objective: This report describes ambulatory medical care visits to nonfederally employed, office-based physicians in the United States during 1995 and 1996. Statistics are presented on selected physician, patient, and visit characteristics.

Methods: The data in this report were collected in the 1995 and 1996 National Ambulatory Medical Care Surveys (NAMCS). The NAMCS is part of the ambulatory care component of the National Health Care Survey (NHCS), which measures health care utilization across a variety of providers. The NAMCS is a national probability sample survey of visits to nonfederally employed, office-based physicians in the United States. Sample data were weighted to produce annual estimates. Estimates are presented in this report as annual averages unless otherwise noted.

Results: During 1995-96, an estimated 1.4 billion visits were made to physician offices in the United States, an annual average of 715.8 million visits. The visit rate was 2.7 visits per person per year. This rate did not differ significantly from visit rates observed in any previous survey year. Females made 59.4 percent of the visits, or 3.2 visits per person annually. This was higher than the visit rate for males. White persons had a higher visit rate than black persons. Six of every 10 visits were to primary care providers. Injury-related visits accounted for 11.8 percent of all office visits, or 84.6 million per year. The annual rate of injury-related office visits was 32.2 visits per 100 persons. The most frequent reason for visiting the physician was for a general medical examination (6.8 percent). Cough was the most frequent symptomatic reason. Acute respiratory infections and essential hypertension were the diagnoses reported most frequently.

Objective: This report describes ambulatory care visits in the United States across three ambulatory care settings--physician offices, hospital outpatient departments, and hospital emergency departments. Statistics are presented on selected patient and visit characteristics for all ambulatory care visits and separately for each setting.

Methods: The data presented in this report are from the 1997 National Ambulatory Medical Care Survey (NAMCS) and the 1997 National Hospital Ambulatory Medical Care Survey (NHAMCS). These surveys are part of the ambulatory care component of the National Health Care Survey that measures health care utilization across a variety of health care providers. NAMCS and NHAMCS are national probability sample surveys of visits to office-based physicians (NAMCS) and visits to the outpatient departments and emergency departments of non-Federal, short-stay and general hospitals (NHAMCS) in the United States. Sample data are weighted to produce annual estimates.

Results: During 1997, an estimated 959.3 million visits were made to physician offices, hospital outpatient departments, and hospital emergency departments in the United States, an overall rate of 3.6 visits per person. Visits to office-based physicians accounted for 82.1 percent of ambulatory care utilization, followed by visits to emergency departments (9.9 percent) and outpatient departments (8.0 percent). Utilization varied by patient age, sex, and race. Persons 75 years and over had the highest rate of ambulatory care visits. Females had significantly higher rates of visits to physician offices and hospital outpatient departments than males did. White persons utilized physician offices at a higher rate compared with black persons. There were an estimated 123.8 million injury-related ambulatory care visits during 1997, or 46.4 visits per 100 persons.

Objective: This report presents data about agencies providing home and hospice care, their current patients, and their discharges. The data are presented in 159 tables according to standard sets of descriptive variables. The tables are grouped into five categories: agencies, home health care current patients, home health care discharges, hospice care current patients, and hospice care discharges. Data are presented on agency characteristics, demographic characteristics, utilization measures, and health and functional status of current patients and discharges.

Methods: The data used for this report are from the National Center for Health Statistics' 1996 National Home and Hospice Care Survey. This is a sample survey through which data are collected on the use of home health and hospice care agencies in the United States. The data were collected by personal interview using three questionnaires and two sampling lists.

Objectives: This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 1996 and selected trend data. Estimates are provided by demographic characteristics of patients discharged, geographic region of hospitals, conditions diagnosed, and surgical and nonsurgical procedures performed. Measurements of hospital use include number and rate of discharges and days of care, and the average length of stay.

Methods: The estimates are based on data collected through the National Hospital Discharge Survey (NHDS). The survey has been conducted annually by the National Center for Health Statistics (NCHS) since 1965. In 1996, data were collected for approximately 282,000 discharges. Of the 507 eligible non-Federal short-stay hospitals in the sample, 480 (95 percent) responded to the survey. Diagnoses and procedures are coded according to the International Classification of Diseases, 9th Revision, Clinical Modification, or ICD-9-CM.

Objectives: This report presents estimates of surgical and nonsurgical procedures performed in the United States during 1996. Data are presented by characteristics of patients, region of the country, and procedure categories for ambulatory and inpatient procedures separately and combined.

Methods: Estimates in this report are based on data collected from the National Hospital Discharge Survey (NHDS) and the National Survey of Ambulatory Surgery-(NSAS). NHDS provides data on hospital inpatient care, and NSAS provides data on ambulatory surgery in hospitals and in freestanding ambulatory surgery centers. For NHDS, data were collected for approximately 282,000 discharges from 480 non-Federal short-stay hospitals (95 percent response rate). For NSAS, data were collected for approximately 125,000 ambulatory surgery discharges from 488 hospitals and freestanding ambulatory surgery centers (81 percent response rate).

Results: An estimated 71.9 million procedures were performed on 39.9 million discharges from hospitals and freestanding ambulatory surgery centers during 1996: 40.4 million procedures were for inpatients, and 31.5 million were for ambulatory patients. Females had more procedures than males, and the rate of procedures increased with age in ambulatory and inpatient settings. The leading procedures for ambulatory surgery patients and inpatients combined were arteriography and angiocardiography, endoscopy of small intestine, endoscopy of large intestine, and extraction of lens.

Objectives: This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 1996. Estimates of first-listed diagnoses, all-listed diagnoses, days of care for first-listed diagnoses, and all-listed procedures are shown by sex and age of patient and geographic region of hospital.

Objectives: This report presents national estimates of ambulatory health care use by children under 15 years of age according to principal diagnosis, place of visit (physician office, hospital outpatient department, and hospital emergency department), and patient characteristics (age, sex, and race).

Methods: Data were from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. Data were from 1993-95.

Results: In 1993-95 children under 15 years of age made 165.3 million visits per year (289 visits per 100 children). Visit rates were highest among infants and varied inversely with age. Visit rates were 43 percent higher among white children than black children. Three-quarters of ambulatory visits occurred in physician offices, 8 percent in hospital outpatient departments, and 14 percent in hospital emergency departments. Visits by white children were more likely to occur in physician offices than visits by black children (81 percent and 54 percent). Conversely, visits by black children were more likely to occur in hospital outpatient departments (19 percent and 7 percent) and hospital emergency departments (28 percent and 12 percent) than visits by white children. The following principal diagnoses accounted for almost 40 percent of visits: well-child visit, 15 percent; middle ear infection, 12 percent; and injury, 10 percent. Rates for well-child visits were almost 80 percent higher among white infants than black infants. Continued monitoring of these differences in use of ambulatory care among children are needed, particularly in view of the possible impact of changes in the health care system on these differences.
