Classification of Recommendations and Levels of Evidence A recommendation with Level of Evidence B or C does not imply that the recommendation is weak. Many important clinical questions addressed in the guidelines do not lend themselves to clinical trials. Although randomized trials are unavailable, there may be a very clear clinical consensus that a particular test or therapy is useful or effective. Ofcial Medicare Program legal guidance is contained in the relevant statutes, regulations, and rulings. It includes information on how and when you can get these benefts and how much you?ll pay. If you have a question about a test, item, or service that isn?t listed in this booklet, visit Medicare. If you have a Medicare Advantage Plan or other Medicare health plan, you have the same basic benefts as people who have Original Medicare, but the rules vary by plan. Some services and supplies may not be listed because the coverage depends on where you live. In 2020, you pay a yearly $198 deductible for Part B-covered services and supplies before Medicare begins to pay its share, depending on the service or supply. Assignment is an agreement by your doctor, provider, or supplier to be paid directly by Medicare, to accept the payment amount Medicare approves for the service, and not to bill you for any more than the Medicare deductible and coinsurance. Depending on the service or supply, actual amounts you pay may be higher if doctors, other health care providers, or suppliers don?t accept assignment. Doctors who don?t accept assignment may charge you more than the Medicare-approved amount for a service, but they can?t charge more than 15% over the Medicare-approved amount for non participating doctors. Your doctor or other health care provider may recommend you get services more ofen than Medicare covers. For more information on how to fle an appeal, see your Medicare & You handbook, download and read the booklet Medicare Appeals at Medicare.

Section 2: Items & services 9 Alcohol misuse screenings & counseling Part B covers an alcohol misuse screening if you?re an adult (including pregnant women) who uses alcohol, but you don?t meet the medical criteria for alcohol dependency. If your primary care doctor or other primary care practitioner determines you?re misusing alcohol, you can get up to 4 brief face-to-face counseling sessions each year (if you?re competent and alert during counseling). Costs You pay nothing if your qualifed primary care doctor or other primary care practitioner accepts assignment. Ambulance services Part B covers ground ambulance transportation when you need to be transported to a hospital, critical access hospital, or skilled nursing facility for medically necessary services, and transportation in any other vehicle could endanger your health. Medicare may pay for emergency ambulance transportation in an airplane or helicopter to a hospital if you need immediate and rapid ambulance transportation that ground transportation can?t provide. In some cases, Medicare may pay for limited, medically necessary, non-emergency ambulance transportation if you have a written order from your doctor stating that ambulance transportation is medically necessary. Costs You pay the Part B deductible and 20% of the Medicare-approved amount to both the ambulatory surgical center and the doctor who treats you. You pay nothing for certain preventive services if the doctor or other health care provider accepts assignment.

Part B covers anesthesia services provided by a hospital if you?re an outpatient or by a freestanding ambulatory surgical center if you?re a patient.
In the event of poor enrollment blood pressure kits at walgreens buy indapamide 1.5mg with amex, sites may be asked to blood pressure 00 order indapamide 1.5mg overnight delivery provide comparable information about patients referred to heart attack information quality 2.5mg indapamide cath without prior ischemia testing blood pressure facts discount indapamide 2.5 mg with amex. The goal of this effort will be to describe the characteristics of patients who are screened but not enrolled and to document the major reasons for exclusion. For analysis, we will compare baseline characteristics and treatment plan of patients who were screened and met inclusion criteria but were not randomized with those who were randomized. This information will provide insight into any potential bias in trial enrollment. Liver transaminases should only be obtained if not available before starting statin therapy. An attempt will be made to coordinate participant follow-up visits so that they occur close in time to routine follow-up visits with their physicians when routine blood tests are performed. At 6 month follow-up visits, if lipid tests (and HbA1c at annual visits for diabetics) are not available within specified time windows they will be obtained by the study coordinator or participants will be referred to their treating physicians for the tests. Participants who give informed consent will be asked to allow storage of samples of their blood in two biorepository protocols, one for biomarkers and one for genetic analysis. Participants who decline participation in one or both of the biorepository protocols are still eligible to participate in the main trial. Although no specific scientific proposals are put forth in the present protocol, we anticipate a wealth of opportunities for ancillary studies and sharing of resources with other investigators. If a site is unable to process blood samples they may still participate in the genetic biorepository; in this case saliva samples may be collected from participants. Blood will be drawn for the biorepository at the time of randomization, and may be drawn after 3 months of follow-up. Strict confidentiality and maintenance of the chain of custody will be observed in the collection and storage of biospecimens. Responses to these brief surveys will be used to tailor counseling for lifestyle change. These assessments will occur at randomization, 3 months, 12 months, annually, and at the closeout visit. We will use these data to analyze the health status of participants in both groups over time to quantify both the magnitude and trajectory of health status recovery as a function of randomized management strategy. The schedule of assessments (Table 2) specifies the preferred method of contact for each visit. In the event that a scheduled clinic visit is not possible, to ensure participant follow-up other forms of contact should be used, such as telephone, email, communication from a personal physician, other allied health professional, or family member, or review of electronic health record or public records. After the first year, participants will be followed every 6 months until the end of the trial, at which time sites will be notified to perform a closeout visit. Dependent on additional funding, telephone or email follow-up every 6 months or ascertainment of database information on vital status may continue after all clinic visits have been completed, unless prohibited by local regulations. At these long-term follow-up contacts, information on current health and medications, and interval hospitalizations will be collected. It may include up to 5 visits over the first 18 months and up to 2 visits per year thereafter until the study ends. Withdrawal from the Study: Complete and accurate follow-up is extremely important for the duration of the study. The participant, however, may decline to continue with their assigned management strategy at any time. If at any time the subject refuses to continue with study visits, every attempt will be made to continue contact by telephone, written communication, email, by proxy contact with family, friends, or allied health care providers, or record review to determine if outcome events have occurred, unless the subject specifically refuses such follow-up. National databases that record deaths will be used to ascertain vital status, unless prohibited by local regulations. The reason for (and the level of) withdrawal will be documented for all subjects withdrawn from the study or for those having limited follow-up. The subject must specify in writing what follow-up (s)he will allow, if any, at the time of withdrawal discussion. B 6, 18, and 30 month visits may be via telephone, email, or in clinic depending on participant stability, risk factor control, and geography. C Following the 36 month visit, follow-up visits should be in clinic visits at least every 12 months. Clinic visits can be replaced by email or phone depending on participant stability, risk factor control, and geography. E Send ischemia test images (immediately following enrollment and before randomization), technical worksheets, and site interpretations/local reports from qualifying ischemia tests to core labs. H Height is only needed at randomization, assessments only required if visit is completed in clinic. I Required labs include: lipids (preferably fasting) at 3 month visit then semiannually only, and HbA1c (at visit 4, 6, 8 and annually thereafter for diabetic participants. Q At every follow-up visit the research team, in collaboration with the treating physician(s), will evaluate effectiveness of medical therapy and optimize as needed according to guideline recommendations and study algorithms. Catheterization and optimal revascularization treatment should be targeted within 30 days after randomization in the Invasive strategy group. In the Conservative group, catheterization and optimal revascularization is reserved for participants with refractory angina symptoms or acute ischemic events. Endpoints to be adjudicated include death (including cause), myocardial infarction, resuscitated cardiac arrest, hospitalization for unstable angina, hospitalization for heart failure, and stroke. Care will be taken to blind reviewers to any information that could identify the participant or could reveal the randomized management strategy assignment. After careful consideration of these and other factors, the sample size was formulated to provide high power to detect a 15% relative reduction. The final sample size was chosen to provide adequate power, even if our current assumptions prove to be optimistic. Loss of power due to protocol non-adherence was reflected in the sample size analysis by computing power with a relatively modest assumed treatment effect (20% vs. Ideally, with perfect protocol adherence, a larger treatment effect would be plausible. Thus we have excellent power even with a more conservative effect size projection. Thus, we have excellent power even with a more conservative estimate of the incidence of the primary endpoint. Power and precision under other assumptions are summarized in Table 3 and Table 4 below. Assumptions: Based on a univariable Cox model with a binary treatment indicator and Wald-type 95% confidence intervals. A statistical analysis plan will be finalized before trial completion and data analysis. The Cox proportional hazards will be the primary analytic tool for assessing outcome differences between the two randomized groups. To preserve power in the face of participant heterogeneity, the overall comparison may be adjusted for a selected set of prognostically important baseline covariates that will be carefully defined and pre specified in the statistical analysis plan. In addition to Cox regression, event-free survival probabilities will be estimated as a function of follow-up time in each treatment group using the Kaplan-Meier method and presented with point wise 95% confidence intervals. If the data provide evidence of an overall difference in outcome between management strategy groups, we will further examine whether the therapeutic effect is similar for all participants, or whether it varies according to specific participant characteristics, which will be pre-specified in the statistical analysis plan. Plans for the analysis of the quality of life and economic endpoints are addressed below in Sections 11. For other secondary endpoints, analysis will be similar to the primary endpoint, using time from randomization until the first occurrence of the specific secondary endpoint as the response variable. Unambiguous operational definitions of each study endpoint will be documented in the Clinical Event Committee Charter and statistical analysis plan before performing unblinded analysis. Although we believe the projected rate is reasonably conservative, an acceptably precise estimate of the true event rate of the primary endpoint will not be known until substantial participant recruitment and follow-up have been accrued. To ensure that the primary analysis is well-powered and useful, a prospective plan to allow extending follow-up and/or changing the primary endpoint based on aggregate event rate data will be established prior to the first review of unblinded trial data. At a designated time during the trial, an analysis will be conducted to estimate the overall aggregate primary endpoint event rate and project the final number of observed events. Members of this panel will not have access to unblinded data by treatment group or other data 62, 63 that may bias their recommendation. First, we will provide simple descriptive and comparative analyses by intention-to-treat.

Conscious level, cardiac ischaemia secondary to poor perfusion of the coronary arteries and blood pressure need to be assessed. Patients with bradycardias with adequate perfusion are treated initially with oxygen and observation. Sinus bradycardia not responding to increased oxygenation is treated with atropine. For other bradycardias the two alternatives are to drive the inherent rate with a sympathomimetic drug or to pace the patient with an external or internal pacer. Unconscious patients with wide complex tachycardia should be treated in a standard cardiac arrest approach. Conscious patients in ventricular fibrillation however, can be treated either chemically or with synchronised cardioversion. If a patient is in cardiac arrest the approach is to establish effective resuscitation and early defibrillation as per Australian Resuscitation Council guidelines. Some are probably the best marker of perfusion in this relatively benign and as such are best not addressed situation. Mean arterial pressure is the key measure looking dramatic are still managing to perfuse the of perfusion but unfortunately is not well related to brain and are better than the alternatives that might measured blood pressure particularly at the extremes of result from an attempt to correct them. The hardest decisions regarding intervention to arrhythmias that are still perfusing is to provide are for patients who, while conscious, are obviously support with oxygen and ventilation while observing not perfusing well and for whom the consequences the patient. The alternative approach of more active of intervention may include an even worse rhythm. If in doubt, an approach the criteria for deciding that an arrhythmia of maximising oxygenation, optimising preload and needs intervention vary with the situation adopting an attitude of optimistic expectancy is the and the support available. The degree of bradycardia and the impact upon perfusion determine whether or not intervention should be considered. Conscious level is a good guide of perfusion, as is evidence of ischaemic chest pain secondary to poor perfusion of the coronary arteries. Blood pressure and other indirect measures of perfusion (the ability to provide a pulse wave detected by a pulse oximeter) are useful adjuncts when assessing perfusion status. Evidence of ischaemia in the right coronary artery territory (inferior leads) in a patient who is not yet bradycardic raises the possibility of bradycardia secondary Figure 2. The initial approach to sinus bradycardia should be to increase oxygenation and ensuring an adequate preload (Figure 3). Simply lying the patient down and raising the legs will improve venous return and improve the preload. The dose of atropine should be at least 1 mg as small doses have been known to paradoxically reduce the heart rate by interfering with the sympathetic system. Bradycardia improving with oxygen either a junctional or a ventricular pace maker (Figure 4). If the patient is symptomatic and oxygen and optimising the preload with posture has already been tried, the two alternatives are to drive the inherent rate with a sympathomimetic drug or to pace the patient with Figure 4. The issue here is balancing improved oxygenation of the coronary muscle with increased oxygen demand. Although improving the heart rate improves coronary artery perfusion pressure and thus oxygenation, oxygen demand rises as heart rate and force of contraction increase. Usually the predominant effect is beneficial from the increase in coronary artery perfusion pressure. Supraventricular tachycardia commonplace and can be easily used as an alternative. The self adhesive pads should be placed on the anterior chest wall and between the shoulder blades for optimum current transmission. It is not a good idea to select too high a rate initially as an increase in heart Figure 6. The current delivered should be quickly increased to a point where capture occurs. Capture will be confirmed by the presence of a complex after each pacing spike and hopefully by the presence of a palpable pulse. In a more intensive setting, formal pacing with an internal wire can be considered. Too fast Tachycardias can also reduce cardiac output as ventricular filling becomes ineffective; they also increase myocardial oxygen demand making ischaemia worse. To do this properly the patient should be supine and a forced expiration against a blocked airway needs to be maintained for at least 15 seconds.
