1、“知情同意書審查”和“倫理學新觀點”,無錫市人民醫(yī)院倫理委員會 時間： 2013年10月29日16:00,要點,一、知情同意書審查 J Karbwang SIDCER 協(xié)調(diào)員二、 涉及人的研究的倫理學新觀點Daniel Wikler, Ph.D.哈佛公共衛(wèi)生學院教授,一、知情同意書審查,J Karbwang SIDCER 協(xié)調(diào)員,如何審查知情同意書,1.

2、Step1: 審查知情同意過程：誰？何時？哪里？怎么做？2.Step2: 審查內(nèi)容是否符合指南要求？3. Step3：審查語言的可理解性4. Step4：評判知情同意是否有效,Step1:知情同意過程,誰？ 合適的人選，例如沒有不正當?shù)挠绊?、脅迫什么時候? 在篩選/入組前 再次知情同意，如：急診病人，無意識病人，知情同意修改等什么地點？ 醫(yī)院：急診室、門診、病房 社區(qū)：學校、家庭、村莊等,知情同

3、意過程：怎樣進行？,足夠的時間寬敞的環(huán)境ICF和招募廣告中簡單充分的信息法定代理人、弱勢群體贊同，弱勢群體需要口頭同意文盲受試者需要見證人,Step2 內(nèi)容：指南要求的審查內(nèi)容,總體：研究/試驗背景；資料保密；誰能接觸受試者的信息；受試者責任；聯(lián)系人科學性：試驗目的和受試者入選條件；研究期限；樣本量；隨機分組情況；研究過程；備選方案及過程自愿參加：可以拒絕參加；有退出權(quán)利；及時獲取新信息權(quán)利，這些新信息決定受試者是否繼續(xù)參與

4、研究,Step3:知情同意書的語言,非專業(yè)性用語：通俗易懂簡潔：以簡潔的語言恰到好處抓到重點考慮當時的環(huán)境,Step4:評判知情同意書的有效性,自愿受試者的權(quán)利相關(guān)信息,知情同意書常見問題,沒有告知受試者為什么適合該研究太長，信息超負荷備選治療及過程信息不充分風險信息不充分（尤其是與受試者相關(guān)的風險）研究過程過于復雜，太多專業(yè)術(shù)語不恰當?shù)脑囼灪螳@益過度保證的語言補償和賠償不清晰,影響自主選擇的因素,研究結(jié)束后支付補

5、償補償金額：過高、過低家庭困難，慢性病（無備選治療）迫于壓力不當影響（主治醫(yī)師）,改進理解,建立一個普遍的名詞解釋制作一個本地的知情同意模板使用海報、流程圖解釋研究過程知情同意過程中使用影像資料預測知情同意工具與受試者群體進行問答,改進理解,病人參觀研究機構(gòu)，熟悉研究過程對病人進行研究過程的教育培訓研究者和工作人員如何使用知情同意書培訓倫理委員會改進審查知情同意書質(zhì)量咨詢社區(qū)人員改進知情同意過程,A New P

6、erspective on the Ethics of Research with Human Subjects涉及人的研究的倫理學新觀點,Daniel Wikler, Ph.D.,注意：PPT中的觀點僅代表作者自己的觀點，不代表哈佛公共衛(wèi)生學院的觀點,1.The Conventional View is based on a series of fictions傳統(tǒng)觀點是基于一系列的杜撰,Does research ethics r

7、equire us to give the highest priority to the individual research subject? 研究倫理是否要求我們將研究受試者個體至于首位？We owe research subjects our best effort to provide the care they need, consistent with the goal of conducting research.

8、我們應盡最大的努力向受試者提供他們需要的醫(yī)護，這與開展研究的目標相一致。But research often requires that the interest of patients be balanced against the requirements of scientific method.但研究常要求患者的利益應平衡與科學方法的要求。Example: the last patient enrolled in a dou

9、ble-blinded randomized clinical trial 例：隨機雙盲研究中最后一名納入的受試者,Research as an unavoidable social obligation研究是不可避免的社會責任,We all want health care that is safe and effective 我們都希望衛(wèi)生保健是安全有效的Safe and effective health care require

10、s research that in some cases may involve discomfort or moderate risk 安全有效的衛(wèi)生保健需要研究，某種情況下會有不適或中度的風險It is unfair to ask others to accept the risk so that you may benefit 要求他人承擔風險而你獲益是不公平的Analogy: the medical student’s f

11、irst spinal tap 類推：醫(yī)學生的第一次腰穿,Justice, Groups, and Individuals (1)公平，群體，個人（1）,Research ethics should require: 研究倫理應該要求Protection from unnecessary risk 保護，以免不必要的風險Informed, voluntary consent to any necessary risk 告知必要的風

12、險，自愿同意Subjects endorse the goal of obtaining knowledge 受試者對獲得知識這個目標表示贊同All risk to subjects must be justified by potential gains to future patients 受試者的所有風險相對于將來患者的潛在獲益是合理的Concern for subjects; humane standards; no br

13、utality 對受試者的關(guān)心，人道標準，沒有暴行,Justice, Groups, and Individuals (2): Some Principles公平，群體，個人（2）：一些原則,No one is “expendable” or less important 沒有人是“可犧牲”或不那么重要的Everyone should bear a fair share of the risks of research, and sh

14、ould receive a fair share of the benefits對每個人應該公平分配研究風險和研究獲益Patients may be asked to endure some discomfort or moderate risk if: 患者應該被征求承受一些不適或適度的風險，如果The research is needed to relieve significant suffering 研究是為了減輕嚴重的苦

15、痛The risk or discomfort is at most moderate 風險和不適至多是中度的All unnecessary risk has been avoided 所有不必要的風險已被避免Patients are fully informed and free to refuse 患者被充分告知并可自由地拒絕,2.Risk-Benefit Ratio 風險-獲益比,Must all risks to part

16、icipants be smaller than expected benefits to participants? 是否受試者所有的風險都應小于受試者預期的獲益?Estimating Risk and Benefit 估算風險和獲益Determining the ethically acceptable ratio 確定倫理可接受的比例Distinguishing between: 區(qū)別在于Research that may

17、 yield benefits to future patients 研究可能對將來的患者帶來獲益Poorly designed research 設計不充分的研究Research performed chiefly for commercial purposes 研究主要是出于商業(yè)目的,Ethics Committees should:倫理委員會應該,Protect human subjects from unnecessar

18、y, inhumane, or unreasonable risk 保護受試者免受不必要，不人道，或是不合理的風險Ensure that any risk is justified by potential benefits to future patients (note: this is an ethical judgment) 確保任何風險相對于將來患者的潛在獲益是合理的Ensure that any patients ask

19、ed to endure risk understand fully what is being asked of them and that they are free to say “no” and to withdraw at any time 確保任何一個被要求承受風險的受試者對風險充分理解并能自由地說“不”，能夠隨時退出。,Ethics committees should not…倫理委員會不應該…,Insist that

20、in all cases, all net expected benefits to individual human subjects always outweigh expected risks. 在任何情況下堅持對受試者個體的凈獲益必須大于預期的風險Fail to estimate potential benefits of research for future patients as well as risks to par

21、ticipants, and make an ethical judgment on whether the risk-benefit ratio is justified. 未能評估研究對未來患者可能帶來的獲益以及對受試者的風險，沒有針對該風險-獲益比進行倫理判斷,Ethics committees should not…倫理委員會不應該…,Judge all research the same way regardless of

22、scientific and humanitarian merit 采取同樣的方法評判所有的研究，忽視科學和人道價值Research performed for commercial purposes with little social value does not justify risks to subjects 出于商業(yè)目的的研究，且沒有什么社會價值，對受試者的風險是不正當?shù)腁ct primarily to protect

23、their institutions from bad publicity or financial or legal difficulty. 采取行動，首先為了保護所在機構(gòu)免受負面宣傳或財務/法律困境。,3.Declaration of Helsinki, #29:赫爾辛基宣言：#29,“ The benefits, risks, burdens and effectiveness of a new method should be

25、ethod exists.”獲益，風險，負擔和一個新方法的有效性必須與那些當今最好的預防，診斷，治療方法進行對照測試。這并不排除一些研究，當沒有已被證明的預防，診斷和治療方法時，使用安慰劑或空白治療。,Three Standards of Care三種標準療法,Helsinki: All receive best current care 所有人都獲得現(xiàn)今最好的治療Helsinki alternative: 赫爾辛基替代選擇A

26、ll are offered care that is no worse than what they would have received had the study not been done 提供給所有人的治療將不差于不參加研究所獲得的治療New proposal: 新的建議All are offered care that is no worse than what they should have received h
