Properly executed order caverta 100 mg with amex erectile dysfunction causes alcohol, Internet applications can help health Health Plans 141 plans rebuild their relationships with hospitals and physicians by reducing or eliminating paperwork and bureaucratic interference with medical practice discount caverta 50mg mastercard does erectile dysfunction cause infertility. Information technology enabled by the Internet can, again if properly executed, bring tangible benefits to consumers that will help them make constructive use of the choice they have demanded. In addition, information systems strategies can help health plans offset a significant percentage of the present cost rise with improved productivity and efficiency and more responsible consumer choices. Connectivity makes all organizations more transparent and ac- countable to customers. Health plans that embrace the need for openness and responsiveness will find their position in the health system strengthened in future years. The health plans that succeed in the digital transformation will not only survive, but also prosper. How government responds to these political pressures and how it structures payment for health services under the Medicare and Medicaid programs will affect both the speed and universality of the changes discussed in this book. Changing healthcare payment methodology Each of these issues will be discussed below. Personal health informa- tion is the most intimate documentary information that exists in the 145 U. Someone with access to this information knows a person’s most carefully guarded secrets—personal medical and psy- chiatric history, sexual orientation and history, lifestyles and their risks, drug history, and a lot of things about relationships with others. Insurers who see the totality of someone’s healthcare use can use that information to estimate how good or bad an insurance risk he or she may be in the future and decide not only if they wish to provide coverage, but also how much to charge for it. That patients disclose this information to physicians is vital to ensuring optimal care. Physicians require it because making intel- ligent treatment decisions is based on understanding medical and personal history and the impact of those decisions on health. If physicians cannot be trusted with intimate personal knowledge, the opportu- nity for injury or death escalates alarmingly. Yet this intimate doctor-patient relationship is really a three-way relationship, in which only two of the parties are physically present. Despite its intimacy, medical information is also among the most widely distributed and poorly protected personal information in our society. Thanks to federal legislation passed in the wake of the highly publicized Congressional hearings of Supreme Court Justice Clarence Thomas, video rental records were actually safer from dis- closure than a patient’s medical records. The main reason is that health costs have grown to the point that they are no longer an affordable personal respon- sibility. As a direct consequence, third parties, typically employers and the health insurers they hire to manage their health costs, de- mand access to this information. With the growth in managed care, health plans use personal health information to establish whether the healthcare they pay for is necessary and appropriate. Because insurers and employers have an economic incentive to minimize their outlays, their interest in obtaining personal medical information has acquired a pungent adversarial odor. Employers with access to employees’ health history may decide they no longer 146 Digital Medicine wish to employ someone or invest in training or promoting that person into a leadership position to avoid being responsible for their medical costs. When someone sees a physician or visits a hospital, he or she is typically required to sign a release that authorizes the provider to release whatever information the health insurer may require to review the medical claim arising from the visit. The result is a legal authorization for the physician to breach medical confidentiality in order to get paid. The information patients authorize physicians to release is not only compared to the health plan’s contract to ensure that the service is covered by the health plan. It is also compared to the informa- tion provided about the employee’s medical history when he or she enrolled in the health plan. The purpose of this review is to determine if the condition for which the patient is being treated predates enrollment in the health plan. If it does, but the employee did not disclose that precondi- tion, the plan can not only refuse to pay the claim, but it may also move to invalidate coverage on the grounds that the employee misrepresented his or her health status. Employees may even be sued for fraud if the health plan can prove that they willfully withheld information and lied when attesting to the completeness of their health history. Because people frequently switch health plans, an individual health plan may not have a complete picture of their medical his- tory and claims experience.

Evidence A Cochrane systematic review has evaluated the effectiveness of multiple risk factor interven- tions for the primary prevention of cardiovascular disease in adults from general populations generic caverta 100 mg line erectile dysfunction at age of 30, occupational groups and high-risk groups (106) discount caverta 100mg on-line erectile dysfunction clinics. Eighteen randomized controlled trials involving counselling and/or health education, with or without pharmacological treatment, which aimed to affect more than one cardiovascular risk factor (smoking, diet, physical activity, blood pressure and blood cholesterol) were included. Overall, modest reductions in smoking prevalence, systolic blood pressure, diastolic blood pressure, and blood cholesterol were observed. The studies with the highest baseline levels of smoking prevalence, diastolic blood pressure or cholesterol levels demonstrated greater intervention-related reductions in these risk factors. The pooled effects of the ten trials with clinical event endpoints showed no significant effect on total or cardiovascular disease mortality; this is consistent with the extent of changes in risk factors. However, trials that focused on participants with elevated blood pressure, and those that used drug treatment, demon- strated significant reductions in coronary heart disease mortality and total mortality. Interventions using personal or family counselling and education, with or without drug treatment, were more effective in modifying risk factors and reducing mortality in people at high risk because of raised blood pressure. These results argue in favour of multiple risk factor interventions for prevention of cardiovascular disease in multifactorial high-risk groups. For the general low-risk population, policy measures that create a conducive environment which facilitates behavioural change may have a greater impact at lower cost than individual counselling and therapeutic approaches. Blood pressure lowering Issue Does lowering blood pressure reduce cardiovascular risk? Evidence Raised blood pressure is estimated to cause about 7 million premature deaths throughout the world, and 4. It is a major risk factor for cerebrovascular disease, coronary heart disease, and cardiac and renal failure. Treating raised blood pressure has been associated with a 35–40% reduction in the risk of stroke and at least a 16% reduction in the risk of myocardial infarction (264). Raised blood pressure often coexists with other cardiovascular risk factors, such as tobacco use, overweight or obesity, dyslipidaemia and dysglycaemia, which increase the cardiovascular risk attributable to any level of blood pressure. Worldwide, these coexisting risk factors are often inadequately addressed in patients with raised blood pressure, with the result that, even if their blood pressure is lowered, these people still have high cardiovascular morbidity and mortality rates (265–267). Almost all clinical trials have confirmed the benefits of antihypertensive treatment at blood pres- sure levels of 160 mmHg (systolic) and 100 mmHg (diastolic) and above, regardless of the pres- 40 Prevention of cardiovascular disease ence of other cardiovascular risk factors (264, 268). Observational data support lowering of these systolic and diastolic thresholds (269, 270). Several trials in patients at high cardiovascular risk (271–273) have confirmed these observational data, showing reductions in cardiovascular morbidity and mortality in people whose blood pres- sure is reduced to levels significantly below 160 mmHg systolic and 90 mmHg diastolic. These trials support the view that, in patients at high cardiovascular risk, with blood pressures in the range 140–160 mmHg (systolic) and 90–100 mmHg (diastolic), lowering blood pressure reduces the number of cardiovascular events. These trial results suggest that treatment for such high-risk patients should begin at the lower blood pressure thresholds. Although women are at lower total risk of cardiovascular disease for a given level of blood pressure, and randomized controlled trials generally include a greater proportion of men than women, the treat- ment thresholds for systolic and diastolic pressure should be the same in men and women (274). Total risk of cardiovascular disease for any given level of blood pressure rises with age. For now, the treatment threshold should be unaffected by age, at least up to 80 years. Thereafter, decisions should be made on an individual basis; in any case, therapy should not be withdrawn from patients over 80 years of age (275, 276). Clinic and population-based survey data continue to suggest that the lower the blood pressure achieved, the lower the rate of cardiovascular events (278–280). In people over 55 years of age, the systolic blood pressure is more important (281), so the primary goal of therapy is to lower systolic blood pressure to 140 mmHg or less. Several trials (277, 282–285) have shown that, in patients with diabetes, reduction of diastolic blood pressure to about 80 mmHg and of systolic blood pressure to about 130 mmHg is accom- panied by a further reduction in cardiovascular events or diabetes-related microvascular complica- tions, in comparison with patients with less stringent blood pressure control (277, 284, 285). In patients with high or very high cardiovascular risk, including diabetes or established vascular or renal disease, therefore, blood pressure should be reduced to 130/80 mmHg or less. These trials have demonstrated reductions in both cardiovascular mortality and morbidity with all three drug classes.
