This degree of standardization would not eliminate competition in the clinical software industry buy cheap malegra fxt 140 mg. Vendors would be free to compete generic malegra fxt 140 mg overnight delivery, as they do today, not only on price, but ease and speed of instal- lation, latency (speed of system response), stability and reliability, user friendliness, and most importantly, depth and sophistication of “knowledgeware”—clinical decision support. Vendors have many opportunities to differentiate their offerings while conforming to a set of minimal technical standards. Medical Error Reporting Because physician order information would be entered in a standard format and the resulting clinical outcomes recorded in a standard format, it would be easy for institutions to track (and therefore to report and disclose publicly) the level of medication errors and other medical errors in healthcare institutions of all types on a uniform basis. They could be reported “blinded” as to practitioner to protect them from malpractice litigation. It is likely that accrediting bod- ies such as the Joint Commission of Accreditation of Healthcare Organizations will require the use of clinical software to monitor and evaluate care patterns as a condition of hospitals obtaining accreditation. Having speciﬁed a minimal clinical information infrastructure for a safer health system, federal law should provide a malpractice “safe harbor” for institutions and practitioners who use these tools, including clinical outcome guidelines. There is precedent here, in the decision by malpractice insurers to rate those anesthesiologists who used pulse oximetry to monitor patient conditions in surgery as safer and eligible for lower rates. More than 85 percent of all Medicare claims are presently ﬁled in electronic form, but much of this is in tape format, which is not fully interactive. The ability to verify coverage and obtain payment quickly, as well as to resolve Medicare billing problems in real time, rather than through paper and telephone interactions, will save the federal government and providers a small fortune in reduced clerical expenses. The lack of standardization of health plans’ data requirements is a major lingering source of unnecessary administrative expense for healthcare providers. Thousands of small hospitals and practitioners will not have the cash, credit, or technical staff to make the transition from paper to electronic charts and billing systems. They will need federal assistance, perhaps in the form of a Hill-Burton-type program. Wealthy institutions should perhaps receive some token federal assistance to underscore the timeliness of needed information sys- tem renovations. But it is not sensible to substitute tax dollars for private dollars that would voluntarily have been spent digitizing hospitals’ clinical and operating systems. Other Challenges and Considerations Earlier, it was argued that hospitals and physicians ought not to maintain the present balkanized medical information structure, with separate and nonlinkable medical records in the hospital and the physician’s ofﬁce. Even where the climate of collaboration be- tween hospitals and physicians would permit a common record system to emerge, present federal laws raise barriers. Hospitals that provided connection by physicians to a clinical record system could be construed as violating federal fraud and abuse regulations, which forbid hospitals from offering services or payment to physicians for using their facilities (the modern variant of an ancient and ethically indefensible practice known as “fee splitting”). Moreover, for the 85 percent of all hospitals that are presently not-for-proﬁt, federal and state tax laws forbid them from providing physicians anything of value. If inurement provisions did not exist, many not-for-proﬁt institutions would function as mere front or- ganizations for proﬁt-making enterprises, funneling tax-free dollars into individuals’ and businesses’ pockets. However, changes in federal law could work to minimize these risks in the public beneﬁt. If clinical information systems by differ- ent vendors all used common formats, medical vocabularies, and coding schemes, no provider could achieve market leverage by “lock- ing in” physicians to using their proprietary medical records system, and the fraud and abuse risk could be alleviated. On the not-for- 164 Digital Medicine proﬁt issue, one could reasonably argue for exempting clinical in- formation systems from inurement provisions on the grounds of markedly improved patient safety resulting from the free ﬂow of clinical information among all the diverse actors in medicine. Moreover, an ethos of personal responsibility for health and health costs is vital to containing future health cost increases. However, the present policy climate in clinical information, on both the ven- dor and provider sides, approaches anarchy. Tens of thousand of lives are needlessly lost every year because of inadequate or poorly coordinated care. Creating the infrastructure and decision support to improve standards of care is a legitimate job for government. Current Medicare and private pay- ment policy contains inappropriate incentives, not only to maximize provider income by doing more, perhaps, than patients may need to care for them, but, by implication, to wait until a disease progresses far enough to justify more lucrative, high-technology intervention. Maintenance of health, disease management, advice and coun- seling—these are not the focus of the current healthcare payment schemes.
They experience substance use disorders just particularly prone to cause dependency buy malegra fxt 140mg on line, are a special case that as others do buy malegra fxt 140 mg. An important Physicians who are experiencing substance abuse problems sel- facet of addressing the issue is learning how to recognize dom receive assistance early in the course of their illness. They substance use problems in medical colleagues, intervening deny the magnitude of the problem, just as others—in their on their behalf, and directing them to the excellent treatment discomfort and uncertainty about how to help—deny what resources that do exist. They fear that reaching out for help might follow-up and monitoring is more constructive than a punitive, result in a report to their training program or to regulatory or disciplinary approach. They are needlessly trapped in their fear and Substance use disorders in physicians shame. Meanwhile, the bystanders who do nothing become Neither epidemic nor inconsequential, the prevalence of seri- part of the problem. This means that, over Recognition the course of a lifetime in practice, nearly one doctor in 10 will There is rarely a single observation that will clearly identify a experience a problem with drug or alcohol abuse or depen- substance-abusing colleague, at least not early in the progres- dence that will have a signifcant and potentially serious impact sion of their illness.

But some mary disorder that, without treatment, can be progressive and clues can be readily apparent to a caring colleague, especially even fatal. It is if they are familiar with the doctor’s baseline behaviour and characterized by a pattern of maladaptive use of substance(s) personality (see textbox).

Waiting until a physician with a substance use problem asks for help, if that time ever comes, can have tragic results. We must pay attention to signs of distress in our colleagues, respecting Case resolution our own visceral empathy and formulating an intervention plan The resident’s colleague alerts the chief resident and as soon as possible. At the least, one or two friendly colleagues program director of her concerns discreetly. They can mediately meet with the resident and request that they make time to talk, offer helpful suggestions and resources, and proceed to the emergency room for an assessment. They can do this without needing to know resident complies, and it becomes clear that the resident with certainty just what the problem might be. The physician health program is notifed, and arrangements are made for an urgent assessment. The If this intervention is rejected or proves to be unhelpful, the resident is placed on medical leave. Two or of treatment, the resident is able to return to work, more individuals, respected by the physician and in a position participate in treatment services and health monitoring, of authority, must intervene in a timely, planned and rehearsed and enjoy a full recovery.

This is the most important reason to use the number needed to treat instead of only P < 0 purchase 140 mg malegra fxt overnight delivery. Two variables with different sample sizes and the most likely have minimal discount 140mg malegra fxt with visa, if any, beneﬁt from the treatment. The area ﬁdence intervals, a larger sample size will lead to narrower 95% conﬁdence under the curves is proportional intervals. The samples on the left with a small sample size are not statistically Effect of effect size on power signiﬁcantly different (p > 0. The ones on the right with Before an experiment is done, effect size is estimated as the difference between a larger sample size have an groups that will be clinically important. The sample size needed to detect the effect size that is statistically predetermined effect size can then be calculated. However, as discussed above, if the sample size is large enough, even a very small effect size may be statistically signiﬁcant but not clinically important. Effect of level of signiﬁcance on power The magnitude of the level of signiﬁcance, α, tells the reader how willing the researchers are to have a result that occurred only by chance. If α is large, the study will have more power to ﬁnd a statistically signiﬁcant difference between 134 Essential Evidence-Based Medicine δ 1 δ 2 P > 0. The results of the group on the left with a small effect size are not statistically signiﬁcantly different (p > 0. The ones on the right with a larger effect size have a result that is statistically signiﬁcant (p < 0. If α is very small, researchers are willing to accept only a tiny likelihood that the effect size found occurred by chance alone. In general, as the level of α increases, we are willing to have a greater likelihood that the effect size occurred by chance alone (Fig. We are more likely to ﬁnd the difference to be sta- tistically signiﬁcant if the level of α is larger rather than smaller. In thecaseontheleftthereisa large standard deviation, while Effect of standard deviation on power on the right there is a small standard deviation. The situation The smaller the standard deviation of the data-sets, the better the power of the on the right will be statistically study. If two samples each have small standard deviations, a statistical test is signiﬁcant (p < 0. When the two normal distributions are compared, the one with the smallest spread will have the most likelihood of being found statistically signiﬁcant (Fig. This is important because a negative result may not be due to the lack of an important effect, but simply because of the inability to detect that effect statistically. From an interpretation perspective, the question one asks is, “For a given β level and a difference that I consider clinically important, did the researcher use a large enough sample size? The three common ways of doing this are through the interpretation of the conﬁdence intervals, by 136 Essential Evidence-Based Medicine using sample size nomograms, and with published power tables. We will discuss the ﬁrst two methods since they can be done most simply without specialized references. For the difference between two groups, it gives the range of the most likely difference between the two groups under consideration. This suggests that a larger study could ﬁnd a difference that was statisti- cally signiﬁcant, although maybe not as large as 25mm. If there were no other evidence available, it might be rea- sonable to use the better drug until either a more powerful study or a well-done meta-analysis showed a clear-cut superiority of one treatment over the other, or showed equivalence of the two drugs. In this case, consider the study to be negative, at least until another and much larger study comes along. Evaluating negative studies using a nomogram There are two ways to analyze the results of a negative study using published nomograms from an article by Young and others. Either method will show, for a study with suf- ﬁcient power, what sample size was necessary or what effect size could be found to produce statistical signiﬁcance. In the ﬁrst method, use the nomogram to determine the effect size that the sample size of the study had the power to ﬁnd. If the effect size that could potentially have been found with this sample size was larger than the effect size that a clinician or patient would consider clinically important, accept the study as negative. In other words, in this study, the clinically important difference could have been found and was not.
