公元前560——前480年，在佛陀釋迦牟尼教導(dǎo)下設(shè)立古印度醫(yī)院。而中國最早的醫(yī)院則始于宮廷御醫(yī)出現(xiàn)的秦漢前期（公元前221年——前220年）。民間醫(yī)院首先起源于社會撫恤組織的建立。

在東方萌芽后一千多年，西方才建立了可以被稱作醫(yī)院的機(jī)構(gòu)；350年醫(yī)院雛形在東羅馬帝國出現(xiàn)。

西方前期醫(yī)院的設(shè)立，與歐洲中世紀(jì)公元476年東羅馬賈斯廷朝代（the

Justinian）與1347年奪去歐洲四分之一人口生命的兩次鼠疫大流行相關(guān)，時疫促進(jìn)了前期醫(yī)院的誕生。

公元4世紀(jì)在羅馬有教會醫(yī)院，屬于修道院。6世紀(jì)以后，西歐開始建立醫(yī)院。542年在法國里昴641年在巴黎建立醫(yī)院。醫(yī)院當(dāng)初兼做旅店，是患病的教徒、旅客和香客的醫(yī)務(wù)所或避難所。由于教會日益把持社會的醫(yī)療組織，特別在中世紀(jì)早期，醫(yī)院的組織與工作都具有宗教性質(zhì)；它的護(hù)理重于醫(yī)療，主要目的在于洗凈病人的靈魂。醫(yī)院的最高理想是對上帝的虔誠，根本不考慮醫(yī)學(xué)科學(xué)技術(shù)的發(fā)展問題。此時的醫(yī)院因其目的不同，名稱各異，例如，照料病人者稱醫(yī)院，接收病人者稱為收容院(asylum)，收容窮人者稱為濟(jì)貧院(hospice)，收容婦女及女孩者稱為婦嬰院(WomenandChildrenCareInstitution)。在整個中世紀(jì)，除在9世紀(jì)出現(xiàn)產(chǎn)科醫(yī)院外，醫(yī)院幾乎不分?？啤?2世紀(jì)后，收容病人的機(jī)構(gòu)進(jìn)一步獨(dú)立，正式醫(yī)院開始興起。第一個正式醫(yī)院是1204年建于羅馬的圣靈醫(yī)院(HospitaloftheHolyGhost)。
