Transatlantic editorial: Institutional investigations of ethically flawed reports in cardiothoracic surgery journals

Year: 2020

Type: editorial

Abstract: A growing body of evidence suggests that research misconduct has been rising steadily over the last few decades. The mass media have sensationalized high profile cases of scientific fraud. Several surveys have attempted to define the incidence of scientific misconduct, but the available evidence is unreliable owing mostly to underreporting of misconduct [1]. An indirect indication of the extent of research misconduct is the incidence of article retractions from the scientific literature, which is tracked by the Retraction Watch database. Among science journals the number of retractions rose from 114 in the 5-year period 1990–1994 to 10 738 in the corresponding period 2010–2014, a 94-fold increase [2]. A well-known survey of early- and mid-career scientists found that 33% said they had engaged in serious misconduct in the previous 3 years [3]. The apparent growth in misconduct may be merely an artefact of increased focus on the issue or it may be real, but the question of a recent surge is not as important as the fact that misconduct is widespread and undermines the foundation of science, which is built on honest and transparent investigation. The federal definition of research misconduct includes 3 topics: fabrication of data, falsification of data and plagiarism. The integrity of science is endangered by many other major and minor adverse practices, however, such as ignoring important aspects of human-subject requirements, failing to present data that contradict one’s own previous research, changing the design, methodology or results of a study in response to pressure from a funding source, submitting the same information to more than 1 publication and giving authorship credit inappropriately [3]. Peer-reviewed professional journals are one of the main channels for conveying scientific information, and they are responsible for ensuring the quality and integrity of the information they publish. The major journals in the field of cardiothoracic surgery have identified more publication misconduct in recent years than they had earlier, reflecting the evidence that suggests increasing misconduct throughout scientific disciplines. Allegations of misconduct come from several sources, including, for example, peer reviewers who find evidence of possible wrongdoing, authors who allege wrongdoing by co-authors and colleagues who charge misconduct by co-workers or competitors. The most common ethics violations in cardiothoracic journals have been redundant publication, but have also included plagiarism, misallocation of authorship and the most serious infractions: fabrication or falsification of data. We have previously described how cardiothoracic journals respond to proven misconduct [4, 5]. When the infraction is redundant (duplicate) publication, sanctions range from a letter of reprimand to a 1- or 2-year ban on publication in the journal, depending on the severity of redundancy. The editor may notify the authors’ home institutions and the editors of other relevant journals. For more serious offences that undermine the veracity of the literature, such as falsification or fabrication of data, the article will be retracted, and the editor may ban publication for 2 or more years, up to a permanent ban, again depending on the severity of the infraction. Notification of the sanction may be sent to the authors’ specialty society organization for further disciplinary action. The editorial staffs of scientific journals take allegations of misconduct seriously, and respond with appropriate sanctions if they are proven true, up to and including prohibition from publishing for a specified time in the offended journal (and sister journals when they are notified), as well as the most serious sanction, retraction of the article from the scientific literature. The operative term here is ‘proven true’, which is more difficult to achieve than it might seem. Some allegations can be investigated and resolved by journal editors, such as redundant publication, failure to obtain required institutional review committee approval and plagiarism. Others, such as fabrication and falsification of data, however, require extensive inquiries that demand fact-finding resources beyond those available to journals. In such cases the journals must rely on the responsible institutions, usually universities, to carry out in-depth investigations to determine the facts of each case and report their findings to relevant entities, such as funding institutions, including federal agencies, and offended journals. Institutions often fail to carry out adequate investigations and reach objectively sound conclusions, even when these are mandated by government agencies that have funded the study in question [6]. The need for a national body to oversee misconduct investigations has been recognized for decades, yet still does not exist [7]. Universities in particular may have incentives to downplay transgressions by members of their faculties, such as potentially adverse financial effects of research funding losses, damage to the reputations of well-known researchers and consequently of the university itself, and loss of publications in high-impact journals [8]. Most likely, however, the reported widespread inadequacy of institutional investigations is related to factors such as the absence of any standardized format, peer review of inquiries, and quality control or oversight for investigations. In an attempt to ameliorate this unfortunate circumstance, a group of experts in research misconduct representing a wide range of disciplines and agencies met recently and developed a checklist for evaluating institutional investigations in the hope that investigating institutions would use the document to ensure that their inquiries were thorough and executed appropriately [6]. Cardiothoracic journals have been hampered in dealing appropriately with some allegations of misconduct when institutional investigations have been poorly managed, have reached ambiguous or unsupported decisions or have conducted their investigation extremely slowly, often extending over several years. Journal editors recognize that when acting alone they are likely to have little influence on correcting institutional malfeasance in investigating allegation of misconduct. Nevertheless, journals can attempt to help institutions provide reports that editors find helpful in making appropriate decisions about submitted or published manuscripts that may be seriously flawed. To that end, the major cardiothoracic surgery journals have developed a checklist against which universities and other institutions can measure their own investigational processes before or after sending their investigational reports to an affected journal (see Appendix). This document is modified from the supplement to Gunsalus et al. [6]. When a cardiothoracic surgery journal receives an allegation of misconduct and communicates those allegations to the responsible institution, it will include a note that specifies the allegations, along with relevant additional materials, and a recommendation that the institution uses the checklist to ensure that their report is as useful as possible to the journal. Whether or not the responsible institution changes or improves its investigational process is up to the institution, of course, but at a minimum the journal will have deployed a potentially effective tool in its efforts to protect the integrity of the cardiothoracic surgery literature.

Conflict of interest: Authors have nothing to disclose with regard to commercial support. Cardiothoracic surgery journals have the responsibility to ensure the integrity of the scientific information they publish. Recent decades have seen a substantial increase in the number of allegations of scientific misconduct throughout science, and surgery journals are no exception. Lacking the required resources, we must rely on the institutions in which such research has taken place to investigate the allegations and determine the facts of the case. Investigations of misconduct allegations often suffer from lack of clear guidance for their conduct, so we have taken the liberty of constructing a checklist designed to aid the evaluation and reporting of your investigation. We hope you find this checklist helpful, as it will help the journal to better assess the nature of the investigation and the conclusions. Adapted from Gunsalus et al. [6].
