How can practitioners use self-collected data from a diabetic patient to achieve their group practice's goal of measured improvement in care. This is a hypothetical case study used to teach health professions' students about control chart methods.
Previous studies showed that increased QT dispersion (QTd) has been observed during episodes of myocardial ischemia or infarction and identify the patients at risk of arrhythmia or sudden death. The objective of this study is to investigate the relationship between coronary artery disease and QTd during the Valsalva maneuver. The study population included 85 subjects (21 with normal coronary arteries, 35 with stable angina pectoris, and 29 with unstable angina pectoris). Twelve-lead surface ECGs were recorded at 50-mm/sec paper speeds and were obtained before the Valsalva maneuver and during the strain phase. The results indicate a significant difference in mean time increase between the control group and the group with stable angina pectoris (mean difference = 16.10 milliseconds, p<0.000), and between the control group and the group with unstable angina pectoris (mean difference = 35.26 milliseconds, p<0.000). The mean difference in time between these groups was also compared (mean difference = 19.17 milliseconds), and was statistically significant (p<0.000). There are some conditions like constipation, severe coughing spells, nausea, vomiting, and carrying or lifting heavy objects that increase intrathoracic pressure and may increase QT dispersion. Therefore, all these conditions should be treated appropriately and carrying or lifting heavy objects is forbidden, especially in patients with coronary artery disease.
Peer Review Organizations (PROs) are charged by the Health Care Financing Administration (HCFA) to assist in protecting the integrity and solvency of the Medicare program. Recent audits of the Medicare program from the Office of Inspector General (OIG) revealed that more than $12 billion Medicare dollars in 1998 were spent in improper payments, with more than 25% attributed to prospective payment system (PPS) hospitals. The Payment Error Prevention Program (PEPP) is an initiative designed by HCFA in 1999 to assist PROs in meeting the goal of reducing payment errors in PPS hospitals. PEPP is implemented through the development of quality improvement (QI) methodologies. These projects are designed to achieve measurable improvements in processes and outcomes of payment errors. PEPP works to reduce payment errors at PPS hospitals through cooperative efforts with Ohio agencies and licensing boards, federal law enforcement organizations, HCFA contractors, hospital medical staffs, and medical and osteopathic associations.
In 1996 Congress enacted legislation which, among other things, substantially cut off Supplemental Security Income payments and food stamps for present and future legal alien residents of the United States, and made it much harder for them to qualify for Medicaid. For low-income elderly immigrants, who constituted more than two-thirds of aliens on SSI, the adverse and potential impacts were substantial in terms of economic hardship and access to health care. In the months that followed, their plight received significant attention from the media and state and local politicians who now had greater economic and social responsibilities thrust upon them. One year later, Congress restored SSI benefits only for aliens who been receiving them before August 22, 1996 and made it easier for them to qualify for Medicaid. Food stamp benefits, however, were not restored. The limited scope of this restoration of benefits means that many of today's older immigrants, as well as those in the future, will be faced with serious problems in meeting their basic income and health care needs.
