Measuring Quality Improvement in Healthcare: A Guide to Statistical Process Control Applications. Explorations in Quality Assessment and Monitoring, Volume I: the Definition of Quality and Approaches to Its Assessment and Monitoring. Explorations in Quality Assessment and Monitoring, Volume II: the Criteria and Standards of Quality. And what about health plan claims databases—are they even accurate at all? What is the best source for inpatient data that reflect the quality of patient care from both a process and an outcome perspective? When working in the out- patient environment, where and how would you obtain data reflecting the level of quality delivered in physician office practices? These are some of the questions that challenge many healthcare leaders as they struggle to develop quality improvement and measurement programs. This chapter clarifies these issues and some myths commonly held by the industry and provides a practical framework for obtaining valid, accurate, and useful data for quality improvement work. Categories of Data: Case Example Quality measurements can be grouped into four categories, or domains: clinical quality (including both process and outcome measures), financial performance, patient satisfaction, and functional status. To report on each of these categories, several separate and distinct data sources may be required. In fact, the challenge is often to collect as many data elements from as few data sources as possible, with the objective of consistency and continuity in mind. For most large and mature quality improvement projects, teams will want to report their performance in all four domains. A clinical outcome report (COR) from Spectrum Health, a large inte- grated healthcare system in Grand Rapids, Michigan, illustrates this point. The Spectrum Health system consists of nine hospitals, a 400,000-mem- ber health plan, and more than 130 service locations throughout western Michigan. This example provides a complete picture of the care delivered to several distinct patient populations by one of the inpatient hospitalist groups, Michigan Medical, a multispecialty group practice with more than 170 healthcare providers in 30 locations across West Michigan. To produce this COR, a variety of data sources was required, including extracts from 117 118 the Healthcare Quality Book the finance and medical record systems. The data were then processed by a third-party vendor who applied a series of rigorous data cleanup algo- rithms and added severity adjustment and industry benchmarks. The result- ing report, or dashboard, contains information for patients with congestive heart failure, ischemic stroke, community-acquired pneumonia, and gas- trointestinal bleeding. The report contains measures of the clinical processes (use of angiotension converting enzyme [ACE] inhibitors, beta-blockers, digoxin, coumadin, natrecor, and echocardiograms), financial performance (length of stay, total patient charges, pharmacy charges, lab charges, X-ray charges, and IV therapy charges), and clinical outcomes (acute renal failure, mor- tality rate, and readmission within 31 days). The measures were selected by the hospitalist team from more than 200 indicators available in the data- base as the most important in assessing the quality and cost of care deliv- ered. The measures also include some of the Joint Commission on Accreditation of Healthcare Organizations (Joint Commission) Core Measures.

SURGICAL STAGING BY SENTINEL LYMPH Radiologic studies–computed tomography (CT) NODE BIOPSY and positron emission tomography (PET)–are also available to clinically stage the regional nodes.

The NCG is hybrid- ized to the multiplexer using indium bump bonds; again blood pressure chart 80 year old purchase hytrin us, this is similar to hybridiza- tion techniques used in IRFPAs. The image is serially input onto the multiplexer through a very narrow, flexible microcable. The ceramic carrier with gold via holes (conducting wires penetrating from the front to the back) provides a mechanically convenient means of routing interconnects from the top side of the device to the back side. By designing the ceramic carrier so that the via holes are in close proxim- ity to the bond pads on the silicon multiplexer, the interconnection can be made with conventional tab bonds (thin gold ribbons fused to interconnects with mechanical pressure). This keeps all the interconnects from protruding above the spherical curved envelope defined by the polished NCG surface and therefore protects the ret- ina from damage and reduces the risk of breaking a tab bond. As discussed later, a critical issue for any neural prosthesis is biocompatiblilty and safety. Because the durations of any tests with the IRP are very short (less than an Stimulation of Large Retinal Tissue Areas 23 channel glass with indium bumps microwires retina silicone microcable silicon multiplexer encapsulation Figure 2. The nanochannel glass (NCG) is hybridized to the multixplexer using indium bump bonds similar to the hybridization tech- niques used in infrared focal plane arrays (IRFPAs). However, as with any electronic medical instrumentation, a major safety issue is electrical shock hazard. The objective of the device is to provide minimal electrical stimulation of retinal tissue using very low vol- tages and the smallest currents possible. During this procedure, the patient must be coupled to the external instrumentation. To protect the patient from any electrical shock, the patient is isolated from high voltages using optocouplers that are powered by low-voltage batteries. Neurophysiology of an IRP Many questions and concerns arise when interfacing an electronic device to neural tissue. One fundamental concern is that because the retina is a thin-layered structure, more than one layer may respond to electrical stimulation. Other questions involve electrode configurations, electrical currents, and pulse shapes, as well as the impor- tant issues of safety and biocompatibility. Preferential Stimulation of Retinal Cell Layers the advantage of stimulating retinal cells other than ganglions was mentioned ear- lier. Experimentally, it has been shown that phosphenes could be elicited in patients with advanced outer retinal degeneration via electrical stimulation (Potts and Inoue, 1970; Weiland et al. These electrically elicited responses require and indicate the presence of functioning retinal cells. As the human RGC axons exit the eye, they become myelinated and form the optic nerve. The cell bodies (somas) of these ganglion cells are mapped over the surface of the retina in a manner that approximates the projection of the visual world onto the surface of the retina. However, at any particular location on the sur- face of the retina, axons from distant sites overlay the individual ganglion cell bodies. If these superficial passing axons were preferentially stimulated, groups of ganglion cells from large areas of the retina would be excited. One might expect the visual perception of such a stimulus to appear as a wedge. On the other hand, if the gan- glion cell bodies or deeper retinal cells were stimulated, one would expect the visual perceptions to be focal spots. RP patients that were stimulated with 50–200-mm- diameter platinum disk electrodes reported seeing spots, not wedges, of light (Humayun et al.
