科技將取代醫(yī)生80%的工作？

????目前許多靠醫(yī)生來(lái)完成的工作,，比如檢查,、試驗(yàn)、診斷,、開方,、行為矯正等,，將來(lái)都可以用傳感器、主/被動(dòng)數(shù)據(jù)收集及分析等技術(shù)來(lái)實(shí)現(xiàn),，甚至它們可以比人類醫(yī)生完成得更好,。但這不是說(shuō)醫(yī)生就可以高枕無(wú)憂了，醫(yī)生需要綜合利用所有數(shù)據(jù),，結(jié)合最近在診療中發(fā)現(xiàn)的問題和患者的病史,，找出患者的癥結(jié)所在。許多診斷和開方的工作可以由電腦來(lái)完成,，甚至有可能電腦會(huì)比一般的醫(yī)生做得更好——尤其是電腦會(huì)考慮更多的選擇,，而且犯的錯(cuò)誤也比人類醫(yī)生少。大多數(shù)醫(yī)生都不可能全部讀完最近5,000篇關(guān)于心臟病的研究文章,，更談不上消化理解了,。而大多數(shù)醫(yī)生的醫(yī)療知識(shí)都是從醫(yī)學(xué)院學(xué)來(lái)的，同時(shí)受于人類認(rèn)知的限制,，一般的醫(yī)生也不可能全部記得10,000多種人類可能患上的疾病和療法,。

????相比之下，電腦更擅長(zhǎng)組織和回憶復(fù)雜信息,，這一點(diǎn)連哈佛醫(yī)學(xué)院畢業(yè)的頂尖醫(yī)生也比不上,。電腦也比一般的醫(yī)生更擅長(zhǎng)整合并均衡考慮病人的癥狀、病史,、行為,、環(huán)境因素，以及群體管理等問題,。另外,，別忘了還有50%的醫(yī)生的醫(yī)術(shù)在平均水平線以下！此外,，電腦的另一個(gè)優(yōu)點(diǎn)就是出錯(cuò)率要比人類低得多,。難道我們不應(yīng)該把這個(gè)優(yōu)點(diǎn)用于我們的健康問題上嗎？

????科技可補(bǔ)人力之不足,，同時(shí)強(qiáng)化我們的力量,，解放醫(yī)生以及醫(yī)護(hù)人員的雙手，讓他們做更多的事情,。最終,，電腦可以取代醫(yī)生80%的工作，同時(shí)增強(qiáng)他們的醫(yī)術(shù)水平,。Lifecom公司的數(shù)據(jù)顯示,，醫(yī)生助理們?cè)谑褂昧嗽\斷知識(shí)引擎后，在不使用實(shí)驗(yàn)室,、不做造影,、不做檢查的情況下,，他們的診斷也有91%是準(zhǔn)確的。Lifecom公司的另一項(xiàng)臨床數(shù)據(jù)表明,，在診斷知識(shí)引擎的幫助下,，75%的病例可以安全地交給護(hù)士進(jìn)行診療，剩下的25%才需要?jiǎng)佑冕t(yī)生,。MassGen公司的一項(xiàng)研究發(fā)現(xiàn),，25%的情況下，被醫(yī)生給出“高風(fēng)險(xiǎn)診斷”的病人,，在醫(yī)生最終做出診斷之前,，都有“大信息量的臨床表現(xiàn)”——換句話說(shuō)，就是出現(xiàn)了明顯的拖延,。而如果醫(yī)生使用了臨床決策支持系統(tǒng)來(lái)分析各種檢查結(jié)果的話,，這種拖延是可以避免的！

????新技術(shù)能讓善于接受新事物的醫(yī)生更好,、更快,，而且更擅于在事實(shí)基礎(chǔ)上完成工作。如今海量的數(shù)據(jù)中隱藏著一個(gè)前所未有的巨大機(jī)會(huì),。一旦我們有了足夠大的數(shù)據(jù)基礎(chǔ),，一個(gè)可訪問的醫(yī)學(xué)研究數(shù)據(jù)庫(kù)，我們就能以前所未有的方式,，鑒定病情和病人的生理反應(yīng),。

????隨著時(shí)間的推移,，醫(yī)生將會(huì)越來(lái)越依賴科技來(lái)進(jìn)行分診,、診斷和決策。最終,，我們需要的醫(yī)生數(shù)量會(huì)變得更少,，而每個(gè)患者都會(huì)享受最好的醫(yī)療服務(wù)。診斷和治療計(jì)劃將會(huì)由電腦來(lái)完成,，同時(shí)選擇更加擅于護(hù)理（而不是診斷能力）的醫(yī)護(hù)人員為患者提供人文關(guān)懷,。我們?cè)僖膊恍枰浪贯t(yī)生那樣壞脾氣的診斷天才與病人進(jìn)行直接接觸，而是讓“電腦醫(yī)生”來(lái)提供診斷,，同時(shí)讓最擅長(zhǎng)人文關(guān)懷的醫(yī)護(hù)人員照顧病人,。

Replacing 80% of what doctors do?

????Much of what physicians do (checkups, testing, diagnosis, prescription, behavior modification, etc.) can be done better by sensors, passive and active data collection, and analytics. But, doctors aren't supposed to just measure. They're supposed to consume all that data, consider it in context of the latest medical findings and the patient's history, and figure out if something's wrong. Computers can take on much of that diagnosis and treatment and even do these functions better than the average doctor (while considering more options and making fewer errors). Most doctors couldn't possibly read and digest all of the latest 5,000 research articles on heart disease. And, most of the average doctor's medical knowledge is from when they were in medical school, while cognitive limitations prevent them from remembering the 10,000+ diseases humans can get.

????Computers are better at organizing and recalling complex information than a hotshot Harvard MD. They're also better at integrating and balancing considerations of patient symptoms, history, demeanor, environmental factors, and population management guidelines than the average physician. Besides, 50% of MDs are below average! Computers also have much lower error rates. Shouldn't we take advantage of that when it comes to our health?!

????Technology compensates for human deficiencies and amplifies our strengths – MDs and less-trained medical professionals can do more. Eventually, computers?will?replace 80% of what doctors do and amplify their capabilities. Lifecom showed in clinical trials that medical assistants using a diagnostic knowledge engine were 91% accurate?without using labs, imaging, or exams. Another clinical study by the same company demonstrated that 75% of cases can be safely triaged to be treated by RNs, with the remainder handled by doctors. A MassGen?study?found that 25% of the time, a medical record for patients who wound up with 'high risk diagnoses' had 'high information clinical findings' before a physician finally made the diagnosis — in other words, there was a significant delay that might have been avoided had a clinical decision support system been used to parse the notes!

????New technologies will make the receptive doctors better at their jobs – quicker, more accurate, and more fact-based. There is a tremendous opportunity in the influx of data that has never before been available. Once we have a large enough dataset, and an addressable database of research studies, we'll be able to identify patterns and physiological interactions in ways that weren't possible before.

????Over time, doctors will increase their reliance on technology for triage, diagnosis, and decision-making. Eventually, we'll need fewer doctors, and every patient will receive the best care. Diagnosis and treatment planning will be done by a computer, used in concert with empathetic support from medical personnel selected more for their caring personalities than for their diagnostic abilities. No brilliant diagnostician with bad manners, a la "Dr. House," will be needed in direct patient contact. Instead, we'll use "Dr. Algorithm" to provide the diagnosis, while the most humane humans provide the care.
