A little gushing discount levitra soft 20mg line erectile dysfunction treatment shots, but a stimu- lating look at the creative aspects of writing generic levitra soft 20mg with mastercard erectile dysfunction treatment wikipedia. There are all kinds of non-linear creative thinking, and the technique of mindmapping, as pioneered by Tony Buzan, is one of the most developed. The author has chosen a wide range of comments, from one-liners to longer pieces, that are written by writers on writing. It does not follow that they are doing it in the most effective way (see false feedback loop). Proofreading This is the task of reading a piece of writing that is about to be published, and identifying any errors that may have crept in during the writing and editing processes. The mistake that authors sometimes make is believing this is an opportunity for them to improve what they have written. It is too late for that, and any attempts to overturn previous technical editing will be distracting and dangerous – risking more serious mistakes. Find yourself a quiet corner so that you can give the proof your full attention. Watch particularly for four types: • misspellings of names of people or their titles; • numbers that are inconsistent within the copy (i. Some say that you should read each proof twice, once for major errors and another for minor ones of spelling and punctuation. Others recommend reading backwards, so that you do not become distracted by the meaning. If possible, enlist the help of other readers: a fresh pair of eyes is far more likely to spot errors that you put there in the first place. Some people are better than others at proofreading: if you do find someone good at the task, cherish them. Propaganda A derogatory term used to dismiss a piece of writing that we believe upholds a viewpoint with which we do not 104 PROPAGANDA agree. When we speak we make use of a wide range of visual cues, such as eye contact and stifled yawns, to help us adjust to our audience and put our message across. When we write, we lose sight of the audience, and spend large amounts of time putting on (an unnecessary) posh overcoat. Whenever you come across a particularly impenetrable piece of prose that you have written, apply the pub test: how would you have explained this to your target reader, face to face? This invariably produces a sentence that is simpler and easier to understand. Once this has been agreed, all kinds of other arrangements have to be made, such as reserving time on the printing press, and summoning extra staff to help with the distribution. Postponing these arrangements is tiresome and costly, which is why we need deadlines. Publication planning Many pharmaceutical organizations now spend time and money working out what papers they need to have published where and by when. But it is usually less bad than many people think (see false feedback loop). But these articles are often badly written and hard to read, few take-home messages seem to get through (see CF Kellett et al. Poor recall performance of journal-browsing doctors, Lancet August 17, 1996), and it can take years for findings to be trans- lated into action. In fact the evidence of market research (and commercial success) shows that these publications, which are written in simpler English, are well read and acted upon. This leaves anyone writing for doctors having to choose: do they follow the style of the journal, and risk being ignored, or follow the style of the medical newspaper, and risk being undervalued? Punctuation Marks that make our writing easier to read (see colons; commas; dashes; exclamation marks; full stops; hyphens; quotation marks; semicolons). Puns Using a word with two meanings and making people smile (or even laugh a little). Beware overuse: The write stuff (as a headline on articles about writing courses) has become a tedious cliché. Putting on the posh overcoat It is hard to escape the feeling that when we write we need to impress (see English teachers). There are clear exceptions – when writing for doctors who believe that writing is of value only when they have to struggle over its meaning.

A patient who undergoes a total knee replacement discount 20 mg levitra soft otc erectile dysfunction urinary tract infection, for example cheap 20 mg levitra soft free shipping erectile dysfunction natural supplements, should experience less knee pain when he or she walks, have a good range of motion of the joint, and be able to perform the activities of daily living that most of us take for granted. In summary, it is important to maintain a balanced perspective of the process of care when designing data collection efforts by collecting data in all four categories: clinical quality, financial performance, patient satis- faction, and functional status. Quality improvement teams who fail to main- tain this balance may experience some surprising results of their improvement efforts. For instance, a health system in the Southwest initially reported on a series of very successful quality improvement projects—clinical care had Data Collection 119 improved, patient satisfaction was at an all-time high, and patient outcomes were at national benchmark status. However, subsequent review of the projects identified that some of the interventions had an untoward effect on the financial outcomes of the process under improvement. Several inter- ventions significantly decreased revenue, and others increased the cost of care unnecessarily. If financial measures had been included in the data col- lection and reporting process, the negative financial effect could have been minimized and the same outstanding quality improvements would have resulted. In the end, the projects were considered only marginally successful because of the lack of a balanced approach to process improvement and measurement. Considerations in Data Collection The Time and Cost of Data Collection All data collection efforts take time and money. The key is to balance the cost of data collection versus the value of the data to your improvement efforts. In other words, are the cost and time of data collection worth the effort? Although this cost-benefit analysis may not be quite as tangible as in the world of business and finance, it is still imperative that the value equation be considered. Generally, medical record review and prospective data col- lection are considered the most time-intensive and expensive forms of data collection. Many reserve these for highly specialized improvement projects or to answer questions that have surfaced following review of administra- tive data sets. Administrative data2 are often considered very cost effective, especially as the credibility of administrative databases has improved and continues to improve through the efforts of coding and billing regulations, initiatives,3 and rules-based software development. Additionally, third-party vendors have emerged that can provide data cleanup and severity adjust- ment. Successful data collection strategies often combine both code- and chart-based sources into a data collection plan that capitalizes on the strengths and cost effectiveness of each. The following situation illustrates how the cost effectiveness of an administrative system can be combined with the detailed information avail- able in a medical record review. A data analyst, using a clinical decision support system (administrative database), discovered a higher than expected incidence of renal failure (a serious complication) following coronary artery bypass surgery. The rate was well above 10 percent for the most recent 12 months (more than 800 patients were included in the data set), and had 120 The Healthcare Quality Book slowly increased over the last six quarters. However, the clinical decision support system did not contain enough detail to explain why such a high number of patients were experiencing this complication or whether this was a complication of the coronary artery bypass graft procedure versus a chronic condition present on admission. To get to the why, the data ana- lyst used chart review to (1) verify that the rate of renal failure as reported in the administrative data system was correct, (2) isolate cases represent- ing postoperative incidence, (3) identify the root cause(s) of the renal fail- ure, and (4) answer additional questions about the patient population that were of interest to the physicians. In this example, the analyst used the administrative system to identify unwanted complications in a large patient population (a screening or surveillance function) and reserved chart review for a much smaller, focused review (80 charts) to validate the incidence and answer why the patients were experiencing the complication. This is an excellent example of the effective use of two common data sources and demonstrates how the analyst is able to capitalize on the strengths of both while using each most efficiently. Collecting the Critical Few Rather than Collecting for a Rainy Day Many quality improvement efforts take the approach of collecting every possible data element just in case we need it. This syndrome of stockpiling just in case versus fulfilling requirements just in time has been well studied in supply chain management and proven to be ineffective and inefficient and create quality issues (Denison 2002). Similarly, in terms of data collection, this approach provides little value to the effort and is one of the biggest mistakes quality improvement teams tend to make. Rather than provide a rich source of information, this approach unnecessarily drives up the cost of data collection, slows the data collec- tion process, creates data management issues, and often overwhelms the quality improvement team with too much data.
