A characterization of the inventory of equipment from seven pilot areas was carried out first (including 264 medical devices). The characterization study concluded that the inventory on a whole is old [exploitation time (ET)/useful life (UL) average is 0.78] and has high maintenance service costs relative to the original cost of acquisition (service cost /acquisition cost average 8.61%). A monitoring of the performance of maintenance service providers was then conducted. The variables monitored were response time (RT), service time (ST), availability, and turnaround time (TAT). Finally, the study grouped maintenance service providers into clusters according to performance. The study grouped maintenance service providers into the following clusters. Cluster 0: Identified with the best performance, the lowest values of TAT, RT, and ST, with an average TAT value of 1.46 days; Clusters 1 and 2: Identified with the poorest performance, highest values of TAT, RT, and ST, and an average TAT value of 9.79 days; and Cluster 3: Identified by medium-quality performance, intermediate values of TAT, RT, and ST, and an average TAT value of 2.56 days.","PeriodicalId":50391,"journal":{"name":"IEEE Engineering in Medicine and Biology Magazine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MEMB.2009.935708","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29147171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phototherapy exposes the infants to light in the range of 400-500 nm to isomerize unconjugated bilirubin in the skin. Any light source that produces this wavelength can be used, including the sun (though there is a risk of sunburn), fluorescent or halogen lamps, or, more recently, light-emitting diodes. Despite the well-established efficacy of phototherapy devices and their relative simplicity-being not much more than a floor lamp-phototherapy devices are too expensive for developing world hospitals to purchase, with typical hospital models ranging from US$3,000 to US$5,000. In addition, the resource-poor setting presents a more challenging engineering problem than most. Phototherapy devices are frequently donated to developing world hospitals. However, donated phototherapy devices typically run for no more than a few months once donated and, even then, offer little value to some hospitals. Given this background, we set out to design a phototherapy device specifically for use in the developing world. As a minimum, we knew that it had to have a light source with an extraordinarily long life span and have battery backup so that it could run during frequent power outages. Our design uses LEDs and is powered by a car or motorcycle battery. In this article, we present the full engineering design cycle, staring with needs identification and continuing through several cycles of engineering field trials and results with comments on the differences between the engineering design cycle executed in, and for, the developing world.","PeriodicalId":50391,"journal":{"name":"IEEE Engineering in Medicine and Biology Magazine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MEMB.2010.936453","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29149444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the process is fraught with obstacles and may appear to be a distraction from more important work in the laboratory, application of technology is crucial to the furthering of the field and to public health in general. A given inventor may not want to take over the administrative tasks of protecting IP, developing a regulatory strategy, and developing a business model, and he or she does not necessarily have to; however, the inventor needs to at least know about the strategies and know there are people to turn to for leadership and guidance outside of the laboratory early in the process. And that can be all an inventor wants to do or can do: to simply turn the invention over to someone else and move on to more research in the hopes that the invention will help improve patients' health and perhaps afford the inventor and the research institution some financial reward. However, in turning an invention over completely, an inventor also loses power over how, for whom, and at what price the invention will be offered, and that is a reason to become more informed about the process, to know what you can ask for, and to stand by your invention's side in whatever capacity you are equipped to do so throughout the entire technology transfer process.","PeriodicalId":50391,"journal":{"name":"IEEE Engineering in Medicine and Biology Magazine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MEMB.2010.936452","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29149442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a high number of lymph nodes are often resected during sentinel and lymph-node dissections, only a relatively small percentage of nodes are found to be metastatic, a fact that must be weighed against potential complications such as lymphedema. Without a real-time in vivo or in situ intraoperative imaging tool to provide a microscopic assessment of the nodes, postoperative paraffin section histopathological analysis currently remains the gold standard in assessing the status of lymph nodes. This paper investigates the use of optical coherence tomography (OCT), a high-resolution real-time microscopic optical-imaging technique, for the intraoperative ex vivo imaging and assessment of axillary lymph nodes. Normal (13), reactive (1), and metastatic (3) lymph nodes from 17 human patients with breast cancer were imaged intraoperatively with OCT. These preliminary clinical studies have identified scattering changes in the cortex, relative to the capsule, which can be used to differentiate normal from reactive and metastatic nodes. These optical scattering changes are correlated with inflammatory and immunological changes observed in the follicles and germinal centers. These results suggest that intraoperative OCT has the potential to assess the real-time node status in situ, without having to physically resect and histologically process specimens to visualize microscopic features.","PeriodicalId":50391,"journal":{"name":"IEEE Engineering in Medicine and Biology Magazine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/MEMB.2009.935722","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29147244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
