Defining Health Services Research

Multidisciplinary field of scientific inquiry that:

Social Factors

Financing

Organization

Management

Technologies

Individual Factors

Access & Utilization

Quality of Care

Cost of Care

Personal & public health & well being

Examines how: Affect:

For individuals, families, organizations & institutions, and communities & populations

Epidemiological data provide the context for the extent of problems

3

Research questions

Epidemiological questions– Prevalence, incidence, risk factors

Service questions– Facility, workforce, services, finance, cost– Access, utilization, outcome

Monitoring questions & Consequences and correlates

– Morbidity, mortality, crime, HIV/AIDS Quality, process, and outcome questions

– Performance measures– Evaluation studies

5

Dataset Considerations

Type of data– Survey vs. administrative

Reporting level– Person, facility

Unit of data– Case, episode, visit

Time– Recency, frequency

Sampling – Census vs. sample

National Survey on Drug Use and Health (NSDUH)

• Sample– Nationally representative sample of U.S. household residents 12 years and older

(permitting state estimates since 2000, e.g., 68,736 completed survey); sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA). Formerly: National Household Survey on Drug Abuse (NHSDA)

• Data Collection– Self-report survey

• Sampling– Stratified/multistage

• Timeframe– Cross-section every 2-3 years since 1972; annually since 1991

• Relevance to Drug Abuse– Use of alcohol, tobacco, and licit and illicit drugs in the past 30 days, past year,

lifetime; includes DSM-IV diagnostic criteria. Also includes questions on mental health, physical health, treatment and other forms of help-seeking; data can be broken out by state.

• Comments– Refusal Rates 16-33%. No coverage of high risk groups not in households.

National Comorbidity Survey (NCS) NCS-Replication (NCS-R)/NCS-Adolescents (NCS-A)

• Purpose

– The National Comorbidity Survey (NCS) was a collaborative epidemiologic investigation designed to study the prevalence and correlates of DSM III-R disorders and patterns and correlates of service utilization for these disorders. The NCS, conducted in 1991-1992, was the first survey to administer a structured psychiatric interview to a nationally representative sample. Follow-up conducted in 2001-02.

– The NCS-R took place in 2001–2003 and refined categories of treatment utilization

– The NCS-A surveys 10,000 adolescents.

• Sample and Data Collection

– The NCS used a household sample of over 8,000 respondents aged 15 to 54 in the non-institutionalized civilian population in the 48 coterminous U.S. and was based on a stratified multistage area probability sample. The study also included a supplemental sample of students living in campus group housing and a non-respondent survey. Diagnoses were based on a modified version of the Composite International Diagnostic Interview (the UM-CIDI), which was developed for the NCS.

• Relevance to Drug Abuse

– Includes diagnoses for substance use; focus on co-occurring mental and substance use disorders; sponsored by the National Institute on Mental Health (NIMH)

Youth Risk Behavior Surveillance Survey (YRBSS)

• Purpose– YRBSS monitors six categories of priority risk behaviors among youth and young adults: tobacco use, alcohol

and other drug use, sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases, unhealthy dietary behavior, and physical inactivity.

• Sample– Includes national, state, territorial and local school-based surveys of high school students since 1991.

• Data Collection & Sampling– In-school self-administered questionnaire designed to protect student’s privacy. Voluntary.

• Relevance to Drug Abuse– Includes questions of alcohol and other drug use, in addition to other risk factors.

• Comments– Only captures those students in school at time of survey. 1997 data includes separate analysis of data for black

and Hispanic students. Schools with substantial numbers of black and Hispanic students were sampled at a higher rate than other schools.

National Longitudinal Survey of Youth (NLSY79)

• Purpose– Data is used to examine a variety of policy issue relating to employment and the workplace,

education, training, family, mobility, substance use, juvenile delinquency, and fertility. • Sample

in past 30 days of various substances. Data can be used to analyze the relationship between drug use and numerous behaviors such as labor-market outcomes, marital status, and fertility.

• Comments– Breadth of information, event history format, cohort design make data useful for analysis.

Limitations are results are cohort specific and subgroup sample sizes can be small.Website: http://www.bls.gov/nls/
