格林維爾醫(yī)院系統(tǒng)大學醫(yī)學中心(Greenville Hospital System University Medical Center)橫跨5個醫(yī)院設施，共有1110個床位和32間手術室，占地9萬平方英尺，為南卡羅來納州的市民提供服務。在該醫(yī)院的7,500名員工中，約有1,000名醫(yī)生。每年，這些醫(yī)生執(zhí)行超過33,000次住院和門診手術大約5200萬美元的費用，約占整個系統(tǒng)總費用的一半。

 

在這種規(guī)模下，昂貴的手術器械（探針）和其他設備錯位或丟失的情況并不少見，因此格林維爾醫(yī)院的材料服務小組力求最大限度地減少資產損失并減少定位OR材料的時間。雖然有無線網絡，但材料服務執(zhí)行總監(jiān)John Mateka認為它不足以滿足醫(yī)院的所有資產跟蹤需求，因此他和他的員工開始研究集成的Wi-Fi，UHF RFID，條形碼和移動計算解決方案。

 

Mateka和他的團隊咨詢了幾個IT集成供應商，最終選擇并開始與位于南卡羅來納州哥倫比亞市的集成業(yè)務系統(tǒng)和服務公司(IBSS)合作。為了提供解決方案的UHF RFID組件，IBSS求助于Jamison Door的工業(yè)門戶部門，該公司通過與領先的RFID技術和解決方案公司ThingMagic的合作，該公司非常熟悉RFID資產跟蹤和損失預防解決方案。

 

“節(jié)省時間和提高生產率是該系統(tǒng)的重要優(yōu)勢。因為我們實施了醫(yī)療保健的SynTrack和RFID門戶網站同步，沒有標簽設備丟失......”

- John Mateka，格林維爾醫(yī)院系統(tǒng)大學醫(yī)療中心材料服務執(zhí)行主任

 

解決方案 

IBSS與Jamison Door合作，設計了一個重型RFID門戶，用于OR亞麻車出口到洗衣房和凈化室。出口門戶包括ThingMagic Mercury6 RFID讀取器和用于讀取標記設備的天線，例如35,000美元至50,000美元的手術器械（探頭），由于其體積小巧，可能會丟失在笨重的亞麻布和擦洗衣物中或垃圾?，F(xiàn)在，當標記項目 - 例如“節(jié)省時間和提高生產力”是該系統(tǒng)的顯著優(yōu)勢時。自從我們實施SynTrack for Healthcare和RFID門戶網站以來，沒有任何標記設備丟失......”

此外，格林維爾醫(yī)院正在整個主要設施部署ThingMagic Astra UHF RFID閱讀器，利用IBSS SynTrack醫(yī)療保健解決方案的RTLS和UHF RFID組合功能，跟蹤近5,000件移動醫(yī)療設備（例如輸液泵）。RFID門戶，Astra讀卡器和RTLS跟蹤技術通過SynTrack應用程序集成，使Greenville的員工不僅能夠知道標記設備的位置，而且具有同等重要性，狀態(tài)，使用效率和使用歷史。

 

SynTrack系統(tǒng)為格林維爾員工提供了掌上電腦和應用軟件，可以定位和映射任何類型的標記資產，然后通過RTLS技術和ThingMagic Astra讀卡器進行跟蹤。通過位置和利用率信息的這種組合，系統(tǒng)生成詳細說明資產使用和歷史的定制報告。Greenville系統(tǒng)還為醫(yī)院管理提供與用于提供與標記資產相關的醫(yī)療服務的流程和資源相關的效率報告。

 

“我們預算有限，我們想要利用現(xiàn)有的思科無線網絡，我們不想被任何可能過時的東西鎖定，”Mateka說。“現(xiàn)在系統(tǒng)已經到位，授權的醫(yī)院工作人員可以通過網絡瀏覽器或移動計算設備訪問SynTrack應用程序，并找到任何類型的標記設備。RTLS技術和/或Jamison Door出口門戶隨時跟蹤OR中的所有內容通過我們的802.11b無線網絡轉發(fā)的信息。用戶可以選擇找到的部分或全部項目，然后在顯示地圖上查看包含位置，對象描述和照片的項目。”

 

IBSS首席執(zhí)行官喬治·門登霍爾博士說：“OR包裝盒必須無菌且隨時可用，SynTrack為員工提供所有推車的可見性，包括狀態(tài)，位置和案例分配。”“經過授權的醫(yī)院人員還可以通過受污染的推車存放，去污和消毒，圍手術期分期和病例分期區(qū)域監(jiān)測設備流量的每個階段。這種對案例推車流程和其他類型支持流程的自動可視性，通過減少搜索設備和手動記錄流程所花費的時間，節(jié)省了寶貴的員工時間。這種可視性還可以提高程序吞吐量并自動化文檔化過程以進行分析和持續(xù)改進。”

 

患者安全

除了確保格林維爾醫(yī)院能夠跟蹤OR內及其整個設施中的標記資產外，關鍵考慮因素還在于確保所選擇的RFID技術不會干擾任何醫(yī)療設備或現(xiàn)有IT基礎設施。

 

“根據JCAHO程序，醫(yī)院進行了自己的獨立測試，以確保系統(tǒng)不會干擾任何其他醫(yī)院設備，包括手術室中使用的所有電子醫(yī)療設備。 我們還進行了一項研究，以確保UHF RFID門戶不會引起心臟起搏器的任何問題，或者危及患者安全。我們的正式測試使我們有信心在醫(yī)院的所有區(qū)域安全地部署主動和被動標簽和讀卡器，以便日常使用，”Mateka說。

 

結果

鑒于醫(yī)院的人工節(jié)省，預防損失，醫(yī)生滿意度和提高生產力，Mateka預計一年內可獲得投資回報。“節(jié)省時間和提高生產率是該系統(tǒng)的重要優(yōu)勢。自從我們實施SynTrack for Healthcare和RFID門戶網站以來，沒有標記設備丟失在垃圾箱中。 最終，我們還希望能夠通過減少損失和我們的利用率歷史報告來減少我們的設備采購，”他說。

 

隨著系統(tǒng)的成功，IBSS和格林維爾醫(yī)院系統(tǒng)正在共同努力，將解決方案擴展到校園的其他區(qū)域，以跟蹤其他重癥監(jiān)護設備。 

 

 

Greenville Hospital Deploys Integrated RFID Solution for Operating Room Asset Tracking

 

The Greenville Hospital System University Medical Center spans five hospital facilities, with 1,110 beds and 32 surgical suites across 90,000 square feet of physical facilities, serving the citizens of upstate South Carolina. Of the hospital?s 7,500 employees, approximately 1,000 are physicians. Each year, these physicians perform over 33,000 inpatient and outpatient procedures, incurring about $52 million in expenses, or about half the total for the entire system.

 

At this size, it was not uncommon for expensive surgical instruments (probes) and other equipment to be misplaced or lost, so Greenville Hospital?s materials services group sought to minimize asset loss and reduce the time spent locating OR materials. Though a wireless network was in place, John Mateka, executive director, materials services, determined it was insufficient to meet all of the hospital?s asset tracking needs, so he and his staff began investigating an integrated Wi-Fi, UHF RFID, bar coding and mobile computing based solution. 

 

Mateka and his team consulted with several IT integration vendors and ultimately selected and began working with Integrated Business Systems and Services, Inc (IBSS) of Columbia, South Carolina. To deliver the UHF RFID component of the solution, IBSS turned to the Industrial Portals Division of Jamison Door, a company very familiar with RFID asset tracking and loss prevention solutions through its work with leading RFID technology and solutions company ThingMagic. 

 

“Time saved and increased productivity are significant advantages of this system. Since we implemented SynTrack for Healthcare and the RFID portals, no tagged devices have been lost…”

 

- John Mateka, executive director, materials services, Greenville Hospital System University Medical Center

 

The Solution 

 

Working with Jamison Door, IBSS designed a heavy-duty RFID portal for the OR linen cart exit to the laundry and decontamination rooms. The exit portals include ThingMagic Mercury6 RFID readers and antennas used to read tagged devices, such as $35,000 to $50,000 surgical instruments (probes) that, because of their compact size, have the potential to be lost within bulkybed linens and scrubs sent to the laundry or the trash. Now when a tagged item – such as a “Time saved and increased productivity are significant advantages of this system. Since we implemented SynTrack for Healthcare and the RFID portals, no tagged devices have been lost…”

 

- John Mateka, executive director, materials services, Greenville Hospital System University Medical CenterGreenville Hospital Deploys Integrated RFID Solution for Operating Room Asset Tracking JADAK Case Study probe or other surgical tool – is read by the portal, an audible alarm is sounded and a flashing red light alerts an OR attendant who locates and retrieves the device before it is mistakenly discarded. Data gathered from this automated process helps hospital management continuously improve the activities associated with asset preparation and use. 

 

In addition, Greenville Hospital is in the process of deploying ThingMagic Astra UHF RFID readers throughout its main facility to track nearly 5,000 pieces of mobile medical equipment (e.g.infusion pumps) by utilizing the combined RTLS and UHF RFID capabilities of the IBSS SynTrack for Healthcare solution. The RFID portals, Astra readers, and RTLS tracking technology are integrated via the SynTrack application, allowing Greenville’s staff to not only know the location of the tagged equipment, but of equal importance, its status, utilization efficiency, and history of use. 

 

The SynTrack system provides Greenville staff with handheld computers and application software that can locate and map any type of tagged asset, which is then tracked via the RTLS technology and the ThingMagic Astra Readers. Through this combination of location and utilization information, the system produces customized reports detailing asset usage and history. The Greenville system also provides hospital management with efficiency reporting related to the processes and resources utilized to deliver health services associated with the tagged assets. 

 

“We had a limited budget, an existing Cisco wireless network we wanted to utilize, and we didn’t want to get locked in to anything that might become outdated,” said Mateka. “Now that the system is in place, authorized hospital staff can access the SynTrack application through a web browser or mobile computing device, and locate any type of tagged equipment. Everything in the OR is tracked constantly by the RTLS technology and/or the Jamison Door exit portal, with the information relayed via our 802.11b wireless network. Users can select some or all of the items found, then view those on a display map that includes location, a description of the object, and a photo.” 

 

“It?s essential that OR case carts be sterile and ready to use, and SynTrack provides staff with visibility of all carts, including status, location and case assignment,” said Dr. George Mendenhall, CEO of IBSS. “Authorized hospital personnel can also monitor each stage of equipment flow through contaminated cart storage, decontamination and sterilization, perioperative staging and the case staging area. This automatic visibility to the flow of case carts and other types of support process flows, frees valuable staff time by reducing time spent searching for equipment and manually documenting processes. This visibility can also increase procedure throughput and automate the documenting process for analysis and continuous improvement.”

 

Patient Safety

 

In addition to ensuring that Greenville Hospital could track tagged assets within the OR and throughout their facilities, a critical consideration was making sure the RFID technologies chosen did not interfere with any medical devices or existing IT infrastructure. 

 

“In compliance with JCAHO procedures, the hospital undertook its own independent testing to make sure the system did not interfere with any other hospital equipment, including all of the electronic medical equipment utilized in the operating room. We also conducted a study to make sure the UHF RFID portals did not cause any issue with pacemakers, or otherwise jeopardize patient safety. Our formalized testing gave us the confidence to safely deploy active and passive tags and readers through all areas of the hospital for everyday use,” said Mateka. 

 

The Results 

 

Given the hospital?s labor savings, loss prevention, physician satisfaction and improved productivity, Mateka expects a return on investment within one year. “Time saved and increased productivity are significant advantages of this system. Since we implemented SynTrack for Healthcare and the RFID portals, no tagged devices have been lost in the trash. Eventually, we also expect to be able to reduce our equipment purchases through a combination of reduced loss and our utilization history reporting,” he said. 

 

With the success of the system evident, IBSS and The Greenville Hospital System are now working together on expanding the solution to other areas of the campus to track additional critical care devices.
