Evaluation of Medicaid Encounter Data |
| Category |
Medicaid and Managed Care, Information Systems,
Quality Assurance |
| Objectives and Description |
This project will evaluate encounter data
collection and analysis systems for Medicaid programs. Initially, two years of Medicaid
encounter data from a primary test state will be used to develop a baseline. At issue will
be the ability to generate standard managed care performance measures and to evaluate
health-care need and utilization by geographic area from encounter data. Then, the
evaluation will be expanded to include and compare data from other states. Findings will
be used to make recommendations for the overall design of encounter data collection and
analysis systems for Medicaid programs. |

National Hospital Discharge Survey |
| Category |
Information Systems |
| Objectives and Description |
The National Hospital Discharge Survey (NHDS)
provides information on inpatient utilization of non-federal, short-stay hospitals in the
United States. The NHDS collects national data on hospital size, geographic location, type
of ownership, medical conditions diagnosed, surgical and non-surgical procedures
performed, patients' length of stay and expected source(s) of payment, and patients'
demographic characteristics. The survey has been conducted annually since 1965. A category
for HMO/PPO was added under 'Expected Source of Payment' for the 1997 NHDS. |

National Health Interview Survey |
| Category |
Information Systems |
| Objectives and Description |
The National Health Interview Survey (NHIS) is
the nation's largest annual health survey providing information on health status, injuries
and illnesses, access to care and insurance coverage. Beginning in 1997, health insurance
was incorporated into the core questionnaire of the survey; previously the information was
collected in supplements. The survey collects detailed data on health insurance coverage,
costs, type of plan, and details of plan operation. The survey specifically addresses
HMOs, IPAs and other managed care plans (e.g., PPOs and POS). Managed care information is
also obtained for persons covered by Medicaid and Medicare managed care plans. Data on
health status, utilization of health care, disease prevention and health promotion and
other data collected in the survey can be analyzed for those in managed care, as well as
compared to the general population and those with other forms of coverage. The NHIS has
been redesigned and automated and serves as the sampling 'nucleus' for many Department of
Health and Human Services' (DHHS) surveys, including the Medical Expenditures Panel Survey
(MEPS). |

National Ambulatory Medical Care Survey
and National Hospital Ambulatory Medical Care Survey |
| Category |
Information Systems |
| Objectives and Description |
The National Ambulatory Medical Care Survey
(NAMCS) and the National Hospital Ambulatory Medical Care Surveys (NHAMCS) collect data on
patient visits for ambulatory care received in physicians' offices and in hospital
emergency and outpatient departments, respectively. In addition to the usual encounter and
demographic data, the 1997-2000 surveys feature new questions designed to measure the
impact of managed care on physician-patient encounters. Included are whether or not: (1)
the patient is a member of an HMO, (2) the visit is a capitated visit, (3) the visit is to
the patient's primary care physician, and (4) pre-authorization was required for the
visit. |
| Outcomes: |
Multiple. Includes the incidence of managed
care visits to ambulatory medical care settings by age, sex, race, expected source of
payment and provider specialty; diagnostic and counseling services provided; treatment
variations; etc. |

Medicaid Managed Care Data Collection
and Reporting |
| Category |
Medicaid and Managed Care |
| Objectives and Description |
In 1997, The National Committee on Vital and
Health Statistics' (NCVHS) Subcommittee on Populations began evaluating the capacity of
the health system to measure health status and health services delivery for the Medicaid
population during and after the transition to managed care. The project has focused on
existing data sources (including existing Medicaid managed care data collection
processes), and on integrating data collection and analysis.
The Subcommittee held several public hearings on
Medicaid managed care, made site visits to Arizona and Massachusetts, and commissioned an
analysis of Medicaid reporting practices which, when finalized, will: (1) identify State
reporting requirements, (2) delineate the types of data and reports currently available
and (3) highlight best practices for ongoing data collection. A contractor also is
developing 'model' or 'prototype' language to assist State Medicaid agencies in their
development of managed care contracts and data systems. |
