Ambulatory and inpatient procedures in the United States, 1995.

OBJECTIVES: This report presents estimates of surgical and nonsurgical procedures performed in the United States during 1995. 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 263,000 discharges from 466 non-Federal short-stay hospitals (92 percent response rate). For NSAS, data were collected for approximately 122,000 ambulatory surgery discharges from 489 hospitals and freestanding ambulatory surgery centers (80 percent response rate). RESULTS: An estimated 69.2 million procedures were performed on 38.7 million discharges from hospitals and freestanding ambulatory surgery centers during 1995: 39.8 million procedures were for inpatients, and 29.4 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 endoscopy of small intestine, arteriography and angiocardiography, extraction of lens, and endoscopy of large intestine.

Detailed diagnoses and procedures, National Hospital Discharge Survey, 1997.

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).

Ambulatory and inpatient procedures in the United States, 1996.

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.

Hospitalizations for injury: United States, 1996.

OBJECTIVES: This report presents national estimates of the 1996 hospitalizations for injury in the United States. Numbers and rates of discharges are shown within sex, age, and racial groups by type of injury. Average lengths of stay and days of care data by injury type are also included. METHODS: Estimates are based on medical abstract data collected in the National Hospital Discharge Survey. Diagnoses are coded according to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). Injuries are defined as ICD-9-CM codes 800-999. External causes of injury are defined as codes E800-E999 (E-codes). RESULTS: In 1996, there were 2.6 million hospitalizations for injury. Fractures resulted in over a million hospitalizations; medical injuries, including adverse effects and complications, were responsible for 666,000 hospitalizations. The medical records for 64 percent of the patients hospitalized for injuries had an external cause-of-injury code (E-code). Elderly people had the largest number and rate of injuries. CONCLUSIONS: Data on injuries requiring hospitalization and characteristics of patients differentially affected can be used to design and target more effective injury prevention programs. Preventing injuries would decrease the considerable pain, disability, and economic impact associated with these conditions.

1995 summary: National Hospital Discharge Survey.

OBJECTIVES: This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 1995. Numbers and rates of discharges, diagnoses, and procedures are shown by age and sex. Discharges are also shown by geographic region of hospital. Average lengths of stay are presented for discharges and selected diagnostic categories. METHODS: The estimates are based on medical abstract data collected through the National Hospital Discharge Survey for 1995. The survey has been conducted annually by the National Center for Health Statistics since 1965. Diagnoses and procedures presented are coded according to the International Classification of Diseases, 9th Revision, Clinical Modification, or ICD-9-CM.

1996 summary: National Hospital Discharge Survey.

OBJECTIVES: This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 1996. Numbers and rates of discharges, diagnoses, and procedures are shown by age and sex. Discharges are also shown by geographic region of hospital. Average lengths of stay are presented for discharges and selected diagnostic categories. METHODS: The estimates are based on medical abstract data collected through the National Hospital Discharge Survey for 1996. The survey has been conducted annually by the National Center for Health Statistics since 1965. Diagnoses and procedures presented are coded according to the International Classification of Diseases, 9th Revision, Clinical Modification, or ICD-9-CM. RESULTS: In 1996, there were an estimated 30.5 million discharges of inpatients, excluding newborn infants, from non-Federal, short-stay hospitals in the United States. The discharge rate was 116 per 1,000 population and the average length of stay was 5.2 days. Five diagnostic categories accounted for more than a million discharges. These were heart disease, delivery, malignant neoplasms, pneumonia, and psychoses. There were 40.4 million procedures performed on hospital inpatients during the same year. About three-fourths of all procedures were in four ICD-9-CM chapters: miscellaneous diagnostic and therapeutic procedures, obstetrical procedures, operations on the cardiovascular system, and operations on the digestive system.

Relationships among states' fiscal and demographic data and the implementation of P.L. 94-142.

This study examined the relationships between state-level fiscal and demographic variables and identification rates and cumulative placement rates for certain categories of special education students in 1976, 1980, and 1983. The study explored the feasibility of using extant national data to study implementation of special education programs. Identification rates for students with learning disabilities and emotional disturbance were associated with level of state per-capita income and proportion of rural school-age population. States with higher per-capita income tended to have higher cumulative placement rates in special classes and all more restrictive settings.
