德國漢諾瓦醫學院Sam Razaeian團隊比較了人和獼猴在肱骨近端骨折治療中的非一致性。2020年12月14日,該研究發表在《英國醫學雜誌》上。
為了比較地中海獼猴與一組外科醫生,在選擇治療方案和預測肱骨近端骨折預後方面的可信度,研究組設計了一項非對照、雙盲、比較的行為分析研究,招募了10位來自德國和美國的骨科創傷外科領域專家,尤其擅長上肢外科手術,以及5隻半自由放養的地中海獼猴。主要結局是衡量評分者之間協議的可靠性。
與專家相比,地中海獼猴在選擇治療方法(非手術或手術)方面的評分可靠性似乎較低,但對於最常受肱骨近端骨折影響的老年獼猴組,它們在選擇治療方法和手術方式方面的表現與專家組相似。
獼猴和專家對預測結果的共識都很差。所有專家幾乎總是錯誤地預測結果,並傾向於低估它。在90位專家的預測中,只有4位(4.4%)是正確的,而在45隻獼猴的預測中,有13隻(28.9%)是正確的。
結果表明,人們對於肱骨近端骨折的治療和預期結果缺乏共識,甚至在人類以外的物種亦是如此。儘管地中海獼猴傾向於更準確地預測臨床結局,但它們協助外科醫生做出一致決定的可靠性受到限制。未來需要進行高質量的研究,以指導外科醫生對這種常見損傷的最佳治療方法做出決策。

Abstract:
Objective To investigate the inter-rater reliability of Barbary macaques compared with an expert group of surgeons for the choice of treatment and predicted outcome of proximal humerus fractures.
Design Uncontrolled, blinded, comparative behavioural analysis.
Setting Germany and United States.
Participants 10 blinded experts in the field of orthopaedic trauma surgery (Homo chirurgicus accidentus), with special focus on upper extremity surgery from Germany and the US, and five Barbary macaques (Macaca sylvanus) from a semi-free range enclosure.
Main outcome measures The reliability of agreement between raters assessed with Fleiss』 .
Results Barbary macaques seem to have inferior inter-rater reliability in comparison with experts for choice of treatment (non-surgical v surgical), but for the geriatric age group most frequently affected by proximal humeral fractures, they performed similarly to the experts in their choices of treatment and choice of surgical procedure. Agreement about predicted outcome was poor among the macaques and slight among the experts. All experts almost always predicted the outcome incorrectly and tended to underestimate it. While only 4 (4.4%) of 90 experts』 predictions were correct, 13 (28.9%) of 45 macaques』 predictions were correct.
Conclusions Consensus on treatment and expected outcomes of proximal humeral fractures is lacking even beyond the human species. Although Barbary macaques tend to predict the clinical outcome more accurately, their reliability to assist surgeons in making a consistent decision is limited. Future high quality research is needed to guide surgeons』 decision making on the optimal treatment of this common injury.
