Conclusion While defining indicators and collecting data play key roles in the quality measurement journey, it should be clear by now that indicators and data serve little purpose unless they are used to test theories and make improve- ments. Focusing on one or even two of the components will guarantee suboptimal performance. Provide an example of a vague operational definition, and then describe what you would do to make the definition more specific and clear. Provide an example of when you would use stratification and when it is appropriate to develop a sampling strategy. Select one sampling method- ology and describe how you would apply it to a quality improvement initiative. Acknowledgments I want to acknowledge the assistance of several colleagues who helped me research information for this section and reviewed initial drafts of the dis- cussion. Karen did a wonderful job of tracking down information on the MDS topic and the numerous components related to this diverse issue. Tina was able to masterfully cut through the extensive detail surrounding the Joint 114 The Healthcare Quality Book Commission Core Indicators and boil it down to a few key points. Lou Ann, who is a nationally recognized expert in the area of coding and med- ical records, was able to narrow this extremely complex field down into a short history with major data sources (e. Finally, Cheryl was able to summarize the essence of the OASIS initiative into an extremely cogent set of points. This form, UB-92, and several other standard forms used by CMS can be found at www. Additional information on the RAI MDS can be found at the CMS web site: www. Information on the OASIS system can be obtained at the CMS web site: www. Additional detail on the Joint Commission Core Measures project can be found at www. Several years ago, I had the opportunity to observe a team that for- got to note when they changed the operational definition of a key indicator. The shift in their data was so dramatic that I asked if they had done anything different when they collected their data. Frequently, a change in the operational definition or sampling plan can produce such a large shift in the data. As I continued asking the staff if anything was being done differently, I finally found a data analyst who recalled a slight modification in the operational definition. Interestingly, this change in the way the indicator was defined coincided with the shift in the results. If the old operational definition had been applied to the more recent data, the results would not have shown a change. Similarly, if the new definition had been applied to the old data, the improved performance would have been observed previously. Wheeler (1993) states this conclusion in a slightly different fashion: When people are pressured to meet a target value there are three ways they can proceed: (1) they can work to improve the system, (2) they can distort the system, (3) or they can distort the data. The exception occurs under one or more of the following condi- tions: (1) small volume of patients, (2) low response rate, or (3) short data collection period. For example, if your hospital has an average daily census of 72 patients and you know historically that the average response rate to the survey was only 10 percent, you would probably send a survey to every patient. Similarly, if you were only going to survey one week out of the entire quarter, you would want to give a survey to every patient. Remember that sampling is an extremely useful tool, but it is not always needed. Do not feel that you have to go out and buy the most recent books on sampling or statistical methods. The basic principles behind mod- ern sampling techniques have been around since the 1940s. Many of the books I have on this subject, for example, are 20 to 30 years old.

An implanted IRP would need to allow photons to pass through its back side. Note that because there is no need for any multiplexing functions, that is, input of imagery onto the chip from an external camera, the design of the silicon chip becomes much simpler. There are no ancillary electronics, as was needed in the case of the test device. Although there are no multiplexing requirements, there are two new requirements. Specifically, these are external power and a command link to ad- just the operation of the IRP. Power and signals can be transmitted to the IRP with an inductively driven coil or antenna (Liu et al. The major on-chip electronic controls needed are adjustments of bias supplies and the biphasic pulse generator, plus the standard digital electronics that supply timing for simultaneous operation of the unit cell sequences. Along with issues of biocompatiblilty is the question of operational lifetime. Similar requirements exist for other electronic implants, such as cardiac pacemakers and cochlear prostheses. Summary The hope of restoring vision to the blind is now believed to be a real possibility using neural prostheses. However, many technical problems remain and many engineering issues must be resolved before complete clinical success is achieved. Not the least of these problems is solving the issues of biocompatibility and the reliability of a device that will be implanted and expected to function without degradation for decades. Ul- timately, the true measure of success will be the acceptance of this approach by the blind community. It is hoped that this success will parallel that of the cochlear im- plant, which although initially slow, continues to grow exponentially each year and is now a fully commercialized medical product.

Imaging Two-Dimensional Neural Activity Patterns in the Cat Visual 3 Cortex using a Multielectrode Array David J. Normann, and Alexei Koulakov The neural mechanisms that mediate each of the complex process of sensory encod- ing, volition, perception, cognition, and memory are distributed over large numbers of individual neurons that in turn are distributed over di¤erent functional centers in the brain. A reasonable hypothesis advanced by systems-level neuroscientists is that the expression of these higher-order brain functions is a direct consequence of and is directly reflected in the coordinated spatiotemporal activity patterns of distributed neuronal ensembles. This hypothesis is beginning to be validated in studies of record- ings of activity patterns in neural ensembles in the visual pathways excited by patterned visual stimuli (Singer, 1993; Warland et al. One of the most challenging problems confronting contemporary systems-level neuroscientists is how to gain access to the responses of large numbers of neurons in order to study this distributed information processing. Two general approaches are being applied in animal models today: (1) direct visualization of neural structures that have intrinsic or extrinsically augmented optical properties that correlate with the activity patterns of neural ensembles (Blasdel and Salama, 1986; Grinvald et al. Localized regions of neural activity are expected to subtlety alter regional optical features, mediated by such factors as blood flow requirements. Accordingly, di¤erential recording of the optical properties of the cerebral cortex at two di¤erent wavelengths provides a signature that is altered by specific neural activity in a fashion that appears to be consistent with maps made with single-electrode electrophysiological techniques. Koulakov These optical visualization techniques provide virtually continuous images from the cortical surface, but these approaches su¤er from shortcomings in temporal reso- lution that today can be mitigated only by multielectrode recording techniques. Spe- cifically, single-microelectrode recordings allow the systems neuroscientist to record the responses of individual neurons (single units) with submillisecond time resolution and with single-neuron spatial resolution. This spatiotemporal resolution cannot be achieved with contemporary optical techniques. In order to extend this capability, electrophysiologists have developed arrays of electrodes that allow one to record simultaneously from large numbers of single units.

Most times cheap 60pills rumalaya amex medications used for anxiety, it took 20-30 days of taking medicinals to stop the enuresis generic rumalaya 60pills without a prescription medicine 230. Among the 43 patients, the longest a patient took the medicinals was 30 days and the shortest length of time was 10 days. Therefore, the author believes the appropriate treatment to stop enuresis is to strengthen, regulate, and supplement the kidneys and secure and contain. Jin Suo Gu Jing Wan secures the kidneys and astringes the essence and, therefore, can be used to treat enuresis due to kidney vacuity. Jin Suo Gu Jing Wan and Liu Wei Di Huang Wan are available in ready-made form from many different companies in North America and Europe.

Forty-four cases were between 3-5 years old, 69 cases were 6-8 years old, 13 cases were 9-13 years old. The frequency of enuresis ranged from two times per week to five times per night, with the majority of patients having enuresis 1-2 times per night. Eighty-two cases were Chinese Research on the Treatment of Pediatric Enuresis 57 difficult to wake when called, 43 cases had a tongue with red sides, 34 cases had a red tongue, and 14 cases had a pale tongue. The tongue fur was thin and yellow in 57 cases, slimy in 26 cases, and peeled in 12 cases. The pulse was bowstring in 96 cases, fine in 14 cases, and slippery and rapid in 16 cases. Treatment method: The basic formula administered in this study consisted of: Bai Shao (Radix Paeoniae Albae), 15-60g mix-fried Gan Cao (Radix Glycyrrhizae), 9g Fu Pen Zi (Fructus Rubi), 9g Yi Zhi Ren (Fructus Alpiniae Oxyphyllae), 9g Shan Yao (Radix Dioscoreae), 9g Gui Zhi (Ramulus Cinnamomi), 3-6g If there was severe qi vacuity, nine grams of Dang Gui (Radix Angelicae Sinensis) and five grams of Wu Wei Zi (Fructus Schisandrae) were added. If the child was difficult to wake, nine grams of uncooked Ma Huang (Herba Ephedrae) and five grams of mix-fried Yuan Zhi (Radix Polygalae) were added. If there was chronic or severe enuresis, 20 grams of Qian Shi (Semen Euryalis) and 20-30 grams of Ying Su Ke (Pericarpium Papaveris Somniferi) were added. Each day, one packet of these medicinals was decocted in water for 30-60 minutes and administered orally. Study outcomes: One hundred thirteen cases were cured, 10 cases improved, and three cases got no improvement.

Forty-two cases were between 3-5 years old, 31 cases were between 6-8 years old, 15 cases were between 9-11 years old, and 16 cases were between 12-14 years old. The course of disease was 1-3 years in 54 cases, 4-6 years in 37 cases, and 7-9 years in 13 cases. These children were all unable to contain themselves, with enuresis during sleep that was frequent and copious and more than one time each evening. Other signs and symptoms included lack of strength, a somber white facial complexion, fear of cold, cold limbs, lack of warmth in the extremities, low back and knee aching and limpness, somewhat less than normal intelli- gence, usually long, clear urination, a pale tongue with thin, white fur, and a fine, deep or slow, deep pulse.

While taking these medicinals, all other medicinals and treatments were stopped. If there was inability to wake from sleep, five grams of Dan Nan Chinese Research on the Treatment of Pediatric Enuresis 59 Xing (bile-processed Rhizoma Arisaematis) and seven grams of Shi Chang Pu (Rhizoma Acori Tatarinowii) were added in order to transform phlegm and arouse the spirit. If there was devitalized intake and sloppy stools, 10 grams of earth-fried Bai Zhu (Rhizoma Atractylodis Macrocephalae) and five grams of Sha Ren (Fructus Amomi) were added in order to fortify the spleen and harmonize the center. If there was shortness of breath and laziness to speak, 10 grams each of Huang Qi (Radix Astragali) and Tai Zi Shen (Radix Pseudostellariae) were added in order to boost the qi and support the righteous. If there was spontaneous perspiration or night sweats 15 grams each of Ma Huang Gen (Radix Ephedrae) and Fu Xiao Mai (Fructus Levis Tritici) were added in order to secure the interstices and stop sweating. Among these, 23 cases took seven pack- ets of medicinals, 37 cases took 14 packets of medicinals, and nine cases took 21 packets of medicinals.
