May 2017 Show Surgeries in Hospital-Based Ambulatory Surgery and Hospital Inpatient Settings, 2014 Claudia A. Steiner, M.D., M.P.H., Zeynal Karaca, Ph.D., Brian J. Moore, Ph.D., Melina C. Imshaug, M.P.H., and Gary Pickens, Ph.D. Introduction Ambulatory surgery (AS), or outpatient surgery, is a planned operation for which the patient is not expected to be admitted to the hospital. Comparison of ambulatory surgery with inpatient surgery is essential for understanding utilization patterns for specific surgical procedures, including changing trends and estimates of total surgical volumes. As the number of surgical procedures capable of being safely performed in an ambulatory setting increases, comparisons of ambulatory surgery with inpatient surgery can also be useful in the evaluation of post-surgical complications, hospital cost savings, and patient experience of care surveys. Self-reported facility estimates from the American Hospital Association suggest that a growing share of all surgeries at community hospitals in the United States are performed in the AS setting (66 percent in 2014, up from 57 percent in 1994),1 although an ambiguous definition for AS introduces variation across facility volume estimates. Recent reports on specific surgical procedure trends in a subset of States also point to a shift from the inpatient surgical setting to the AS setting.2,3 Nationally representative AS estimates for a broad group of surgical procedures do not yet exist. This Healthcare Cost and Utilization Project (HCUP) Statistical Brief presents national data on surgeries performed in two hospital settings: hospital inpatient and hospital-based AS settings. The findings in this Statistical Brief represent an update and expansion of 2012 statistics previously reported.4 Procedures performed in freestanding (non-hospital-owned) AS centers were not included because many State AS data sources do not include these types of centers. The analysis was limited to visits for an invasive surgery commonly performed for therapeutic purposes (i.e., to treat disease or injury); excluded were noninvasive surgeries and surgeries typically used for diagnostic or exploratory purposes (e.g., colonoscopy). The HCUP Surgery Flag Software for the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM)5 and the HCUP Surgery Flag Software for Services and Procedures6 were used to identify invasive, therapeutic surgeries based on a narrow and targeted definition.7 This report presents characteristics of outpatient surgery visits and hospital inpatient stays for invasive, therapeutic surgical procedures. All references to surgeries, outpatient surgeries, or ambulatory surgeries refer to this subset of surgeries. We also present the distribution of outpatient surgeries compared with inpatient surgical procedures by payer, body system, and the most common surgical procedures performed in an outpatient setting overall and by payer. In addition, ambulatory and inpatient volume and procedure rates are compared for each procedure. Unless otherwise noted, volumes and rates are based on all-listed procedure codes.

Abbreviations: AS, ambulatory surgery; CCS, Clinical Classifications Software; OR, operating room; GI, gastrointestinal Data Source The estimates in this Statistical Brief are based upon data from the Healthcare Cost and Utilization Project (HCUP) 2014 National Inpatient Sample (NIS) and 2014 nationwide ambulatory surgery analytic file created from the State Ambulatory Surgery and Services Databases (SASD), weighted for national estimates. This report evaluates both inpatient and outpatient surgery data. SASD from 22 States were used to create the nationwide ambulatory surgery analytic file: California, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Maryland, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New York, North Carolina, North Dakota, Oklahoma, Oregon, Pennsylvania, South Dakota, and Texas. The ambulatory surgery analytic file included 2.0 million unweighted discharges. The study population in the ambulatory surgery analytic file includes discharges with invasive, therapeutic surgeries from community, nonrehabilitation hospitals with a service type of either general acute care or children's hospital. Weights for national estimates were developed using stratification on hospital characteristics (census region, bed size, location/teaching status, ownership). Supplemental sources included population denominator data for use with HCUP databases, derived from information available from the Bureau of the Census.8 Definitions
Procedures, ICD-9-CM, Current Procedural Terminology (CPT®), and Clinical Classifications Software (CCS) Procedures on inpatient hospitalization records are coded using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM); procedures on ambulatory surgery and services records can be coded using either ICD-9-CM or the CPT. ICD-9-CM and CPT both assign numeric codes to procedures; ICD-9-CM is limited to procedures in the inpatient setting. There are approximately 4,000 ICD-9-CM procedure codes and 9,600 CPT procedure codes. CCS categorizes ICD-9-CM procedure codes into a manageable number of clinically meaningful categories.9 This clinical grouper makes it easier to quickly understand patterns of procedure use. When CPT was used on ambulatory surgery records, the CCS for Services and Procedures10 was used to classify procedures into groupings comparable to the CCS. Case definition
For this report, records from the NIS meeting the following criteria were included:
Therefore, the implied hierarchy of surgeries can be considered as follows:
Types of hospitals included in the HCUP National Inpatient Sample Types of hospitals included in HCUP State Ambulatory Surgery and Services Databases Unit of analysis Hospital location Payer
Hospital stays billed to the State Children's Health Insurance Program (SCHIP) may be classified as Medicaid, Private Insurance, or Other, depending on the structure of the State program. Because most State data do not identify patients in SCHIP specifically, it is not possible to present this information separately. For this Statistical Brief, when more than one payer is listed for a hospital discharge, the first-listed payer is used. About HCUP The Healthcare Cost and Utilization Project (HCUP, pronounced "H-Cup") is a family of healthcare databases and related software tools and products developed through a Federal-State-Industry partnership and sponsored by the Agency for Healthcare Research and Quality (AHRQ). HCUP databases bring together the data collection efforts of State data organizations, hospital associations, and private data organizations (HCUP Partners) and the Federal government to create a national information resource of encounter-level healthcare data. HCUP includes the largest collection of longitudinal hospital care data in the United States, with all-payer, encounter-level information beginning in 1988. These databases enable research on a broad range of health policy issues, including cost and quality of health services, medical practice patterns, access to healthcare programs, and outcomes of treatments at the national, State, and local market levels. HCUP would not be possible without the contributions of the following data collection Partners from across the United States: Alaska Department of Health and Social Services About Statistical Briefs HCUP Statistical Briefs are descriptive summary reports presenting statistics on hospital inpatient, ambulatory surgery, and emergency department use and costs, quality of care, access to care, medical conditions, procedures, patient populations, and other topics. The reports use HCUP administrative healthcare data. About the NIS The HCUP National Inpatient Sample (NIS) is a national database of hospital inpatient stays. The NIS is nationally representative of all community hospitals (i.e., short-term, non-Federal, nonrehabilitation hospitals). The NIS includes all payers. It is drawn from a sampling frame that contains hospitals comprising more than 95 percent of all discharges in the United States. The vast size of the NIS allows the study of topics at the national and regional levels for specific subgroups of patients. In addition, NIS data are standardized across years to facilitate ease of use. Over time, the sampling frame for the NIS has changed; thus, the number of States contributing to the NIS varies from year to year. The NIS is intended for national estimates only; no State-level estimates can be produced. The 2012 NIS was redesigned to optimize national estimates. The redesign incorporates two critical changes:
The new sampling strategy is expected to result in more precise estimates than those that resulted from the previous NIS design by reducing sampling error: for many estimates, confidence intervals under the new design are about half the length of confidence intervals under the previous design. The change in sample design for 2012 necessitates recomputation of prior years NIS data to enable analysis of trends that uses the same definitions of discharges and hospitals. About the SASD The HCUP State Ambulatory Surgery and Services Databases (SASD) include encounter-level data for ambulatory surgeries and may also include various types of outpatient services such as observation stays, lithotripsy, radiation therapy, imaging, chemotherapy, and labor and delivery. The specific types of ambulatory surgery and outpatient services included in each SASD vary by State and data year. All SASD include data from hospital-owned ambulatory surgery facilities. In addition, some States include data from facilities not owned by a hospital. The designation of a facility as hospital-owned is specific to its financial relationship with a hospital that provides inpatient care and is not related to its physical location. Hospital-owned ambulatory surgery and other outpatient care facilities may be contained within the hospital, physically attached to the hospital, or located in a different geographic area. In order to provide information that is comparable across all States, analysis was restricted to hospital-owned ambulatory surgery.
