Public health surveillance data: legal, policy, ethical, regulatory, and practical issues
Bernstein AB , Sweeney MH . MMWR Suppl 2012 61 (3) 30-4 In the United States, data systems are created by the ongoing, systematic collection of health, demographic, and other information through federally funded national surveys, vital statistics, public and private administrative and claims data, regulatory data, and medical records data. Certain data systems are designed to support public health surveillance and have used well-defined protocols and standard analytic methods for assessing specific health outcomes, exposures, or other endpoints. However, other data systems have been designed for a different purpose but can be used by public health programs for surveillance. Several public health surveillance programs rely substantially on others' data systems. An example of data used for surveillance purposes but collected for another reason is vital statistics data. CDC's National Center for Health Statistics (NCHS) purchases, aggregates, and disseminates vital statistics (birth and death rates) that are collected at the state level. These data are used to understand disease burden, monitor trends, and guide public health action. Administrative data also can be used for surveillance purposes (e.g., Medicare and Social Security Disability data that have been linked to survey data to monitor changes in health and health-care use over time). |
Emergency department visitors and visits: who used the emergency room in 2007?
Garcia TC , Bernstein AB , Bush MA . NCHS Data Brief 2010 (38) 1-8 Since 1996, demand for emergency services in the United States has been rising (1). While the number of emergency departments (EDs) across the country has decreased, the number of ED visits has increased (1). As a result, EDs are experiencing higher patient volume and overcrowding, and patients seeking care are experiencing longer wait times (2,3). As national health care costs continue to rise and policymakers become increasingly interested in ways to make the health care system more efficient, it is important to understand the characteristics of those individuals who use EDs--often in place of other sources of ambulatory care. |
Health care utilization among adults aged 55-64 years: how has it changed over the past 10 years?
Freid VM , Bernstein AB . NCHS Data Brief 2010 (32) 1-8 KEY FINDINGS: The percentage of physician office and hospital outpatient department (OPD) visits during which an MRI/CT/PET scan was ordered doubled, to 4%, and the percentage of hospital emergency department visits with an MRI/CT scan more than tripled, to 16%. The percentage of physician office and OPD visits with at least five drugs prescribed more than doubled, to 25%. Inpatient hospitalization rates were similar in 2006 and 1996, but the types of procedures and surgeries performed have changed. Hospitalization rates for coronary artery stent insertions, hip replacements, and knee replacements rose sharply, while rates for some other procedures declined. Ambulatory surgery visit rates were almost twice as high in 2006 as in 1994-1996, and for some types of ambulatory procedures, such as colonoscopies, the increase was even greater. |
