建設(shè)更加智能的醫(yī)院：

醫(yī)院為何迅速采用射頻識別的醫(yī)療柜

智能醫(yī)院正在減少醫(yī)療保健方面的浪費(fèi)

全球醫(yī)療體系面臨的壓力比以往任何時(shí)候都要大。盡管需求在增加，但強(qiáng)制執(zhí)行更嚴(yán)格的預(yù)算，推動(dòng)醫(yī)療保健機(jī)構(gòu)尋找任何可能改善的來源，以降低成本、節(jié)省時(shí)間和提高患者安全性。改進(jìn)的一個(gè)潛在來源是采用新技術(shù)，特別是在自動(dòng)化和可追溯性方面，例如條形碼掃描儀、機(jī)器視覺和射頻識別(RFID)。

RFID已經(jīng)成為實(shí)現(xiàn)這項(xiàng)任務(wù)的關(guān)鍵角色，使醫(yī)院能夠無線追蹤物品和人員。從手術(shù)器械到血液樣本，rfid正被用在“智能醫(yī)院”中建立智能設(shè)備網(wǎng)絡(luò)。RFID技術(shù)支持耗材追蹤，病人和工作人員身份識別，錯(cuò)誤預(yù)防和防偽的藥物跟蹤以及資產(chǎn)/設(shè)備跟蹤。這些解決方案最終可以改善病人護(hù)理，優(yōu)化工作流程，降低運(yùn)營成本，避免錯(cuò)誤并減少昂貴的盜竊。對于原始設(shè)備制造商（OEM）而言，能夠?yàn)榭蛻籼峁?ldquo;智能產(chǎn)品”是成功的關(guān)鍵，在某些情況下，甚至有助于保護(hù)可消費(fèi)的收入來源。

RFID智能醫(yī)療柜

被稱為“智能櫥柜”的rfid醫(yī)療柜是智能醫(yī)院生態(tài)系統(tǒng)的一個(gè)組成部分。它們在醫(yī)療保健機(jī)構(gòu)中越來越受歡迎，因?yàn)樗鼈儍?yōu)化了工作流程，提高了病人的安全性，并降低了成本。他們通過各種手段實(shí)現(xiàn)這一目標(biāo)，例如庫存和寄售庫存管理、跟蹤高價(jià)值醫(yī)療設(shè)備，以及藥品的安全使用。他們允許醫(yī)院人員快速、安全和準(zhǔn)確地分發(fā)藥物。此外，曾經(jīng)是手動(dòng)，乏味的任務(wù)現(xiàn)在已經(jīng)實(shí)現(xiàn)了自動(dòng)化：每個(gè)被移除或添加的物品都會被醫(yī)療柜自動(dòng)記錄下來，節(jié)省時(shí)間并消除人為錯(cuò)誤。

隨著美國面臨阿片類流行病，“藥物轉(zhuǎn)移”已成為醫(yī)療機(jī)構(gòu)面臨的一個(gè)重大問題。澄清：藥物轉(zhuǎn)移涉及將任何法律規(guī)定的受管制物質(zhì)從其開處的個(gè)人轉(zhuǎn)移給另一人以供任何非法使用。智能醫(yī)療柜可以防止醫(yī)護(hù)人員盜竊麻醉藥品。RFID通過對機(jī)柜進(jìn)行實(shí)時(shí)盤點(diǎn)確保操作人員只獲取他們被授權(quán)的數(shù)量。

智能醫(yī)療柜在哪里被采用?

任何部門都采用智能醫(yī)療柜，有效的庫存管理和消費(fèi)品跟蹤至關(guān)重要。這包括：

- 組織蛋白酶實(shí)驗(yàn)室

- 手術(shù)室和ICU

- 急診科

- 介入放射學(xué)實(shí)驗(yàn)室

- 藥房與診所

- 病人樓層

智能櫥柜如何工作？

1. 每個(gè)柜子都配有一個(gè)讀取器，記錄每個(gè)事務(wù)（即，什么被移除并且是誰操作的移除）。支持RFID的機(jī)柜可以采用標(biāo)準(zhǔn)的EPC Gen 2超高頻（UHF）無源RFID標(biāo)簽和閱讀器，但機(jī)柜也可以使用高頻。

2. 柜中的每一個(gè)項(xiàng)目都用一個(gè)小型RFID標(biāo)簽來標(biāo)記，標(biāo)簽包含了有關(guān)物品的基本信息。在一些醫(yī)院里，物品會被預(yù)先貼上標(biāo)簽。

3. 所有相關(guān)人員攜帶一張RFID識別卡訪問機(jī)柜。這可能是他們現(xiàn)有的徽章（通常是高頻）或?qū)ｉT針對機(jī)柜的獨(dú)立訪問卡（可以使用高頻或超高頻）。

4. 通常，需要外部讀取器來檢查進(jìn)出柜子的物品，作為對輸入或移除物品的雙重驗(yàn)證。

與醫(yī)院的信息系統(tǒng)集成后，實(shí)時(shí)數(shù)據(jù)可以直接發(fā)送給供應(yīng)商，分銷商和制造商，從而使整個(gè)供應(yīng)鏈能夠準(zhǔn)確查看庫存水平和使用情況。這樣可以在庫存量不足時(shí)自動(dòng)重新訂購耗材。

痛點(diǎn)

任何醫(yī)療機(jī)構(gòu)過期或召回的藥物，空貨架，放錯(cuò)產(chǎn)品和庫存缺失都是重大的問題。無法追蹤和管理個(gè)別項(xiàng)目可能會導(dǎo)致效率低下和患者護(hù)理不足。設(shè)備和供應(yīng)商需要實(shí)時(shí)數(shù)據(jù)到項(xiàng)目級別的庫存位置和當(dāng)前狀態(tài)。這是RFID技術(shù)提供最大價(jià)值的地方。以下是智能醫(yī)療柜旨在緩解的幾個(gè)主要難點(diǎn)：

為什么醫(yī)院要采用智能櫥柜?

具有RFID功能的醫(yī)療柜可以以最少的時(shí)間和IT資源投入即時(shí)提供投資回報(bào)。以下是通過RFID智能機(jī)柜可以實(shí)現(xiàn)的一些主要優(yōu)勢：

RFID醫(yī)療

智能醫(yī)療柜的使用實(shí)例

通過智能機(jī)柜托管庫存是庫存管理最好的例子。例如，一家骨科植入物制造商已安排在醫(yī)院代銷他們的植入物。因?yàn)樗麄冎辉谑褂煤蛨?bào)告產(chǎn)品時(shí)才得到報(bào)酬，所以他們在使用和收入以及高昂的運(yùn)輸成本之間會有明顯的滯后。由于手工存貨盤點(diǎn)，錯(cuò)位產(chǎn)品和高額庫存成本導(dǎo)致了損失，因此，大多數(shù)大型分銷商和制造商正在尋找獲得自動(dòng)化、實(shí)時(shí)庫存和定單的方式并不奇怪。

這樣的公司將獲得嵌入RFID讀取器的定制安全柜，負(fù)責(zé)存儲和分類植入物。除了跟蹤使用的植入物之外，讀者還可以驗(yàn)證并記錄訪問該單元的任何個(gè)人的身份。當(dāng)連接到制造商的訂單和履行系統(tǒng)時(shí)，醫(yī)院可以確保他們將在正確的時(shí)間擁有合適的產(chǎn)品，同時(shí)制造商可以在產(chǎn)品檢索后立即開票。這種情況也適用于擁有自己庫存的醫(yī)院，例如手術(shù)用品和其他消耗品。

結(jié)論

減少浪費(fèi)和消除醫(yī)療系統(tǒng)的低效是一個(gè)全球性的挑戰(zhàn)。通過減少手動(dòng)定位和供應(yīng)監(jiān)控中的手工勞動(dòng)和人為錯(cuò)誤，RFID功能的醫(yī)療柜已被證明是主要的改進(jìn)來源; 減少錯(cuò)放和被盜物品; 有效使用可能過期的時(shí)效藥物; 并消除潛在危險(xiǎn)的召回藥物。盡管智能櫥柜可用于多種行業(yè)，但由于與這一行業(yè)相關(guān)的獨(dú)特挑戰(zhàn)，它們在醫(yī)療保健系統(tǒng)中尤其有價(jià)值。例如：

- 高價(jià)值的醫(yī)療器械和產(chǎn)品

- 由于患者可變性導(dǎo)致的高度不可預(yù)測的產(chǎn)品消耗

- 由于醫(yī)療程序的緊急性，難以追蹤庫存

- 在寄售過程中管理的產(chǎn)品缺乏問責(zé)制而導(dǎo)致的產(chǎn)品到期和追蹤問題

BUILDING A SMARTER HOSPITAL:

WHY HOSPITALS ARE RAPIDLY ADOPTING RFID-ENABLED MEDICAL CABINETS

SMART HOSPITALS ARE REDUCING WASTE IN HEALTHCARE

Pressures on the global healthcare system are more profound than ever. Mandates are enforcing stricter budgets even though demand is increasing, driving healthcare facilities to seek out any source ofpotential improvement that will reduce costs, save time, and improve patient safety. One potential source of improvement is the adoption of new technologies, especially in automation and traceability, such as barcode scanners, machine vision, and radio frequency identification (RFID).

RFID has established itself as a key player in achieving this task by enabling hospitals to wirelessly track both items and people. From surgical instrument to blood samples, RFID is being used to createa network of smart devices throughout these “Smart Hospitals”. RFID-enabled technologies allow for consumable tracking, patient and staff identificationⁱ, medication tracking for error prevention and anti-counterfeitingⁱⁱ, and asset/device trackingⁱⁱⁱ. These solutions ultimately improve patient care, optimize workflow, reduce operating costs, avoid error, and reduce costly thefts. For Original Equipment Manufacturers(OEMs), being able to offer customers “smart products” is crucial to success, and in some cases it even lends to the protection of consumable revenue streams.

RFID-ENABLED SMART MEDICAL CABINETS

RFID-enabled medical cabinets, known as “Smart Cabinets”, are an integral part of a smart hospital’s ecosystem. They are becoming popular among healthcare facilities because they optimize workflow, increase patient safety, and reduce cost. They accomplish this through various means, such as inventory and consignment stock management, tracking high value medical devices, and secure access to pharmaceuticals. They allow hospital personnel to dispense medications quickly, safely, and accurately. In addition, what was once a manual, tedious task, is now automated: every item removed oradded to the medical cabinet is recorded automatically, saving time, and eliminating human error.

With America facing an opioid epidemic, “drug diversion” has become a huge issue in medical facilities. To clarify: Drug diversion involves the transfer of any legally prescribed controlled substance from the individual for whom it was prescribed to another person for any illicit use^iv. Smart medical cabinets can prevent the theft of narcotics by healthcare workers. RFID allows for real time inventory ofthe cabinet making sure that the operator only takes the amount for which they are authorized.

Where are smart medical cabinets being adopted?

Smart medical cabinets are being adopted in any department where efficient inventory management and consumable tracking is critical. This includes:

- Cath-labs

- Operating rooms and ICUs

- Emergency departments

- Interventional radiology labs

- Pharmacies and Clinics

- Patient floors

How does a smart cabinet work?

1. Each cabinet is equipped with a reader that records each transaction (i.e., what was removed and who removed it). RFID-enabled cabinets can employ standard EPC Gen 2 Ultra High Frequency (UHF)passive RFID tags and readers, but cabinets can also utilize HF.

2. Each item in the cabinet is labeled with a small RFID tag that contains basic information about the item. In some hospitals, items arrive pre-tagged.

3. All relevant personnel carry an RFID-enabled access card to gain access to the cabinet. This could be their existing badges (which is usually HF) or a separate access card specific to thecabinet only (which could utilize HF or UHF).

4. Often, an external reader is needed to check items in or out of the cabinet as a double verification of items entered or removed.

When integrated with the Hospital’s information system, real-time data can be sent directly to vendors, distributors, and manufacturers giving the entire supply chain an accurate view of inventory levels and usage. This allows supplies to be automatically re-ordered when inventory is running low.

PAIN POINTS

Expired or recalled medications, empty shelves, misplaced product, and missing inventory are significant problems in any medical facility. The inability to track and manage individual items can lead toinefficiencies and inadequate patient care. Facilities and vendors need real-time data into the location and current state of inventory at the item-level. This is where RFID-enabled technologies provide thelargest value. Here are a few of the main pain points smart medical cabinets aim to alleviate:

WHY HOSPITALS ARE ADOPTING SMART CABINETS

RFID-enabled medical cabinets can provide immediate ROI with a minimal investment of time and IT resources. Below are a few of the main benefits that can be achieved through RFID-enabled smart cabinets:

EXAMPLE OF SMART MEDICAL CABINET IN USE

Inventory management is best exemplified through consigned inventory in a smart-cabinet. Take, for instance, an orthopedic implant manufacturer who has arranged to sell their implants on consignment ata hospital. Because they only get paid when the product is used and reported, they experience a significant lag between usage and revenue and high carrying costs. Compound this with lost revenue dueto misplaced/stolen product and high stocking costs associated with manual inventory checking, and it is no surprise that most large distributors and manufacturers are looking for a way to obtainautomated, real- time inventory and order placement.

Such a company would obtain a customized, secure cabinet embedded with an RFID reader responsible for storing and cataloging the implants. In addition to tracking what implants were used, the readerwould also verify and record the identity of any individual accessing the unit. When connected to the manufacturer’s order and fulfillment system, the hospital is assured they will have the right product atthe right time, while the manufacturer can bill immediately upon product retrieval. This scenario also works for Hospitals who own their own inventory, such as surgical supplies and other consumables.

CONCLUSION

Reducing waste and eliminating inefficiencies in healthcare systems is a global challenge. RFID-enabled medical cabinets have proven to be a major source of improvement by reducing manual labor andhuman error involved in manual tacking and monitoring of supplies; reduction of misplaced and stolen items; efficient use of time-sensitive pharmaceuticals that may expire; and elimination of potentiallydangerous recalled drugs. Although smart cabinets can be used in a variety of industries, they are particularly valuable in the healthcare system due to the unique challenges associated with this industry,such as^v:

- High value medical devices and products

- Highly unpredictable product consumption due to patient variability

- Difficult inventory tracking due to urgency of medical procedures

- Product expiration and tracking issues caused by a lack of accountability for products managed under a consignment process^vi

There are many different ways in which RFID can be used to improve processes and increase efficiencies. Smart cabinets are just one component of the “smart hospital” ecosystem.
