13 Surgical audit and research ANAL YSING A SCIENTIFIC ARTICLE ANAL YSING A SCIENTIFIC ARTICLE The simplest way to analyse an article from a scientific journal is to look at the checklist of requirements for good scientific research. A group of scientists and editors developed the Consolidated Standards of Reporting Trials (CONSORT) statement to improve the quality of reporting of RCTs. Looking in detail at the study design is often the best way of deciding whether a trial is of value. The CONSORT document includes a checklist for the conduct of good RCTs ( Table 13.3 ). Often clinicians overlook biases that others find obvious to detect, which can have a profound influence on the outcome of any study . Even the randomised design does not always guarantee quality , and a core component of systematic review is the grading of trial quality; several scoring systems have been developed (e.g. Jadad score). Recent guidelines have been published formalising the methods of systematic review and meta-analysis (Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA] guidelines), and also many other types of article. These can be found in the instruc tions to authors of most surgical journals, which will now only accept articles that follow those rules.

AUDIT AND SERVICE EVALUATION AUDIT AND SERVICE EVALUATION Clinical audit is a process used by clinicians who seek to improve patient care. The process involves comparing aspects of care (structure, process and outcome) against explicit criteria and defined standards. Keeping track of personal that a surgeon’s own performance is monitored continuously and can be compared with a national data set to ensure compliance with agreed standards. Involvement in active audit processes is also an essential component of revalidation for the individual surgeon in the UK. If care falls short of the guidance standard being compared against, some change in the way that care is organised should be proposed. This change may be required at one of many levels. It might be an individual who needs training or surgical equipment that needs replacing. At times, the change may need to take place at the team level. Sometimes, the only appropriate action is change at an institutional level (e.g. a new antibiotic policy), regional level (provision of a tertiary referral centre) or, indeed, national level (screening programmes and health education campaigns). There are two main types of audit in common practice – single site/local audits and multisite regional, national or international audits. Both are designed to improve the quality of care. In an ideal world local audits might identify needs closest to the patient, which can then be further investig in multisite larger scale audits. For example, hospital topics are often identified at departmental morbidity and mortality meetings, where issues relating to patient care are discussed. The reporting process might identify a possible national issue, and a national or international audit could be designed to be delivered by local surgical teams. Audits are formal processes that require a structure. The following steps are essential to establish an audit cycle: 1 Define the audit question in a multidisciplinary team. 2 Identify the body of evidence and current standards. 3 Design the audit to measure performance against agreed standards based on strong evidence. Seek appropriate advice (local audit department in the UK) and ensure insti tutions have agreed to undertake the audit. 4 Measure over an agreed interval. 5 Analyse results and compare performance against agreed standards. 6 Undertake gap analysis: a if all standards are reached, reaudit after an agreed interval; b if there is a need for improvement, identify possible interventions such as training, and agree with the involved parties. 7 Reaudit. A new type of audit that has developed significant trac tion in surgery over recent years is the ‘multicentre snapshot audit’, whereby many collaborators across multiple hospitals prospectively collate anonymised patient-level data for a spe cific condition, presentation or intervention over a short time period of normally around 6–8 weeks. This allows explora tion of di ff er ences in patients, techniques and management across the cohort to identify areas of practice variability that may result in apparent di ff erences in outcome.

Key advantages of these snapshot audits are their easy accessibility and the fact that they can be conducted at almost zero cost, so they can be an excellent means of bringing a new group together to collaborate and create contemporaneous and ‘real-world’ data together.

AUDIT OR RESEARCH AUDIT OR RESEARCH? Health professionals are expected to undertake audit and service evaluation as part of quality assurance. These usually involve minimal additional risk, burden or intrusion for partici pants. It is important to determine at an early stage whether a project is audit or research, and sometimes that is not as easy as it seems. T he decision will determine the framework in which the study is undertaken. In the UK, the Health Research Authority (HRA) has developed a decision tool to help decide whether your project is classified as research (http://www .hra-decisiontools.org.uk/research/). This tool crystallises the di ff erentiation between audit and research to three overarching questions: 1 Are the participants in your study randomised to di ff erent groups? 2 Does your study protocol demand changing treatment/ care/services from accepted standards for any of the patients/service users involved? 3 Is your study designed to produce generalisable or trans - ferable findings? - Although the first two questions are simple to comprehend, the third can create some confusion at times. The HRA states that, in this context, ‘generalisable’ means the findings can be reliably extrapolated from the study to a br oader population of patients/service users and/or applied to settings or con - - texts other than those in which they were tested. The majority of audits can be assumed to be hypothesis generating as they would require subsequent prospective testing in a new popula - tion before findings could be considered as new ‘evidence’ – as . The such they do not fulfil this generalisability criterion. Finally , in this context, ‘transferable’ means that the findings of a qualita - tiv e study can be assumed to be applicable to a similar context or setting. Most qualitative studies are not usually generalisable - but can quite often be considered to be transferable. Further useful information on classifying your proposed project can be found in the HRA leaflet ‘Di ff er entiating clinical audit, service evaluation, research and usual practice/surveil - lance work in pub lic health’ (http://www .hra-decisiontools. org.uk/research/docs/DefiningResearchTable_Oct2017-1. pdf). - How to review a journal article and determine • its value AUDIT OR RESEARCH?

EVIDENCE-BASED SURGERY EVIDENCE-BASED SURGERY Surgical practice has been considered an art: ask 50 surgeons how to manage a patient and you will probably get 50 di ff erent answers. There is so much clinical information available that no surgeon can know it all. Evidence-based surgery is a move to find the best ways of managing patients using clinical evidence from collected studies. It was estimated that su ffi cient evidence to justify routine myocardial thrombolysis for heart attacks was available years before the randomised clinical studies that finally made it clinically acceptable; no one had gathered all the available information together. Centres such as the Cochrane Collaboration have been collecting randomised trials and reviews to provide up-to-date information for clinicians. The Cochrane Library presently includes a database of systema tic reviews, reviews of surgical e ff ectiveness and a register of controlled trials. The BJS been collecting surgical randomised trials on its website archive for 20 years (www .bjs.co.uk) . As evidence accumulates, it is expected that this will gradually smooth out the di ff erences between clinicians as the best way of managing patients becomes mor e obvious. Collecting published evidence together and analysing it often requires reviews of multiple randomised designed to interpret multiple findings and synthesise the - results of multiple studies.

Eliminating bias Eliminating bias It is important to imagine how a study could be invalidated by thinking of things that could go wrong. One way to eliminate any bias inherent in the data collection is to have observers or recorders who do not know which treatment has been used (blinded observer). It might also be possible to ensure that the patient is unaware of the treatment allocation (single blind). In the best randomised studies, neither patient nor researcher is aware of which therapy has been used until after the study has finished (double blind). Randomised trials are essential for testing new drugs. In practice, however, in some surgical trials, randomisation may not be possible or ethical.

Ethics Ethics In the first instance, common sense is the best guide to whether or not a study is ethical. It is still important to seek advice from an independent research ethics committee whenever research is contemplated. In the UK the requirement is that an NHS Research Eth - ics Committee (NHS REC) provides an independent ethical review of all health and social care research if it involves - patients and/or carers. The Go vernance arrangements for - Research Ethics Committees (GafREC) provides detailed guid - ance about NHS REC review requirements. The application for NHS REC review is made using the Integrated Research Application System (IRAS). IRAS enables entry of informa - - tion about the pr oject once, instead of duplicating information in separate application forms for regulators. If the study does not require review b y an NHS REC, the need for an independent ethical review should still be con - sidered. Universities have developed their own ethical review infrastructure and this will be institute specific and loca tion specific. For collaborative research, local ethical review should be obtained wher e possible, and developing a local ethics infrastructure should be considered if it does not already exist. Duplication of ethical review should be avoided. Ethics committee forms may seem long and detailed, but it is important that these are filled in correctly as this helps to All dealings with ethics committees should be intelligent and courteous. It is important to attend the meeting at which the study will be discussed, if invited, as it provides a forum for direct communication in relation to the study . It can save time as possible concerns of the ethics committee can be addressed at the time, avoiding lengthy correspondence.

FORMING A TEAM FORMING A TEAM One of the most common reasons for the failure of an other wise good research project is failure to involve others. Only the smallest single-centre project can be delivered by an individual researcher working alone; almost any project worth doing will need a team to deliver it. This team can bring the necessary skills and e xperience to help bring the project to fruition but also, and perhaps more importantly , it can provide the momen tum required to keep pushing a project through to completion when the inevitable hurdles are met. There may be local colleagues who form a natural team for a project, perhaps with the oversight of an experienced trainer or mentor. Another solution can be to get involved in a collaborative research gr oup. Surgery has led the way with collaborative research working over recent years. The first trainee-level research collaborative in the UK was formed in 2008 when a group of surgical trainees who shared the same frustrations around the challenges of conducting high-quality research while eng aged in a full-time training programme came together to create the West Midlands Research Collaborative (WMRC). The premise was simple: to create and conduct prospective r esearch projects that simultaneously collate data from across all of the members’ - units and to take advantage of the rotation of trainees’ postings between units to ensure project longevity and thus enable longer term outcome collection. By achieving a critical mass of engaged members in these projects, the collective momentum ensured completion even if individuals were - unable to personally contribute in a consistent manner because of examinations, family life or busy clinical periods. Such research collaboratives can be most e ff ective in undertaking two key types of study: (i) simple randomised controlled trials (RCTs) and (ii) multicentre snapshot audits (see Audit and - service evaluation ). The first RCT undertaken by the WMRC was the ROSSINI trial, which explored the clinical e ff ectiveness of a simple wound-edge protection device in reducing wound infections after abdominal surgery . A network of trainees mobilised 21 units f or the trial and together they completed - the trial 2 /uni00A0 months ahead of schedule, having randomised 760 patients over a 23-month period, completing in January 2013. This achievement galvanised the research collaborative model and stimulated other new groups to form. There are now general surgical research collaboratives in every region of the UK and national collaboratives for each surgical subspeciality area such as neurosurgery and cardiothoracic surgery . Many other countries with rotational surgical training programmes have also formed their own par - allel collaboratives, including Australia, Portugal, Italy , The Netherlands and Canada. The collaborative movement has Coverage Availability Internet PubMed comprises more than 25 million citations for biomedical literature from MEDLINE, life science journals and online books Citations may include links to full-text content from PubMed Central and publisher websites Internet Full-text archive of biomedical and life sciences journal literature at the US National Institutes of Health’s National Library of Medicine Subscription Providing extensive coverage of peer- reviewed biomedical literature, along with indexing, searching and information management tools Cumulated index to nursing and allied health Subscription literature Internet Preparing, updating and promoting the accessibility of Cochrane Reviews published online in The Cochrane Library tice, engaged thousands of surgical trainees and their consul tant mentors and created an active network of research active clinicians at many hospitals across the world. In the UK, trainee collaboratives have, to date, developed at least 10 RCTs and been awar ded competitive grant fund ing worth over £8 /uni00A0 million. The model has also extended to medical student collaboratives (STARSurg), and all 42 medical sc hools in the UK now have an active network student research collaborative. More r ecently , similar research collaboratives have also formed, utilising the established core principles, in non-surgical specialities such as anaesthetics, gastroenterology and elderly care. All of these collaborative groups work on a principle of complete inclusivity – any interested person is very welcome to get involved in the collaborative; both in existing projects and in suggesting new ideas. People can join at any stage fr om medical student to consultant. Anyone interested in sur gical research should seek out their local or national surgical research collaborative group and get involved.

A network of trainees mobilised 21 units f or the trial and together they completed - the trial 2 /uni00A0 months ahead of schedule, having randomised 760 patients over a 23-month period, completing in January 2013. This achievement galvanised the research collaborative model and stimulated other new groups to form. There are now general surgical research collaboratives in every region of the UK and national collaboratives for each surgical subspeciality area such as neurosurgery and cardiothoracic surgery . Many other countries with rotational surgical training programmes have also formed their own par - allel collaboratives, including Australia, Portugal, Italy , The Netherlands and Canada.

All of these collaborative groups work on a principle of complete inclusivity – any interested person is very welcome to get involved in the collaborative; both in existing projects and in suggesting new ideas.

Anyone interested in sur gical research should seek out their local or national surgical research collaborative group and get involved. FORMING A TEAM One of the most common reasons for the failure of an other wise good research project is failure to involve others. Only the smallest single-centre project can be delivered by an individual researcher working alone; almost any project worth doing will need a team to deliver it. This team can bring the necessary skills and e xperience to help bring the project to fruition but also, and perhaps more importantly , it can provide the momen tum required to keep pushing a project through to completion when the inevitable hurdles are met. There may be local colleagues who form a natural team for a project, perhaps with the oversight of an experienced trainer or mentor. Another solution can be to get involved in a collaborative research gr oup. Surgery has led the way with collaborative research working over recent years. The first trainee-level research collaborative in the UK was formed in 2008 when a group of surgical trainees who shared the same frustrations around the challenges of conducting high-quality research while eng aged in a full-time training programme came together to create the West Midlands Research Collaborative (WMRC). The premise was simple: to create and conduct prospective r esearch projects that simultaneously collate data from across all of the members’ - units and to take advantage of the rotation of trainees’ postings between units to ensure project longevity and thus enable longer term outcome collection. By achieving a critical mass of engaged members in these projects, the collective momentum ensured completion even if individuals were - unable to personally contribute in a consistent manner because of examinations, family life or busy clinical periods.

In addition, few others in the hospital use more technology or devices on a day-to-day basis than surgeons. It is therefore beholden upon all surgeons to be able to critically evaluate both our individual performance and the impact of adaptations in techniques, devices and treatment pathways on the individual and collective outcomes of our patients. Involvement in research and audit activities will form a sta ble cornerstone within a long and successful surgical career. The aim of this chapter is to outline both how to undertake a successful audit cycle and how to design and conduct a surgical research study . Key aspects associated with enhanced chances of a successful project are discussed, including how collabora tion with others can be crucial. Large numbers of clinical papers appear in the surgical literature every year. Many are flawed, and it is important that a surgeon has the skills to examine publications critically best way to develop a critical understanding of the research and audit undertaken by others is to perform studies of one’s own. The hardest part of audit and research is writing it up, and the hardest article to write is the first. This chapter con tains the information required to write a surgical paper and to evaluate the publications of others.

Even when results are negative, they are worth distributing; no project if properly conducted is worthless. Under-reporting of negative outcomes causes a systematic bias in the literature in favour of positive trials. Most studies do not provide dramatic results, and few surgeons publish seminal articles. The key to both presentation and publication is to decide on the message and then aim for an appropriate forum. Big important randomised studies or national audits merit presen tation at national or international meetings and publication in international journals . Small observational studies and audits Alejandro R Jadad Bechara , b.1963, Canadian–Colombian physician, University of Toronto, ON, Canada. - - are more often accepted for presentation at regional meetings and for publication in smaller specialist journals. Help and - advice from clinicians familiar with presentation and publica - tion are invaluable at this stage. The most important piece of advice is to follow accurately the instructions for journal sub - mission. Most international meetings will accept presentations eagerly (especially by poster) as this increases the attendance at a conference . Most surgeons publish research in peer-reviewed journals . The work that is submitted is checked anonymously by other surgeons before publication. If in doubt about whether to sub - mit to a journal, many editors will give advice about the suit - ability of an article for submission to their journal. It is usually free to publish in surgical journals since the cost of refereeing and editing is borne by the journal subscriber. A second model of publication is becoming mor e prevalent: open access, in which the author pays. This ensures that all research is visible to anyone, by pushing the costs of the editorial process onto the - study budget. It may well become standard in future. Convention dictates that articles are submitted in IMRAD form: introduction, methods, results and discussion. Increas - (CONSORT) checklist for authors.

For now , the IMRAD for mat remains inviolable. The length of an article is important: a paper should be as long as the size of the message. Readers of large randomised multicentre trials need to kno w as much detail about the study as possible; reports on small and simple trials should be brief. /uni25CF Introduction . This should always be short. A brief background of the study should be presented and then the aims of the trial or audit outlined. /uni25CF Methods . The methodology and study design should be given in detail. It is important to identify potential biases. New techniques or investigations should be detailed in full; if they are common practice or have been described else where, this should be referenced instead of described. /uni25CF Results . Results are almost always best shown diagram matically using tables and figures. Results shown in the form of a diagram need not then be duplicated in the text. /uni25CF Discussion . It is important not to repeat the introduc tion or reiterate the results in this section. The study should be interpreted intelligently and any suggestions for future studies or changes in management should be made. It is prudent not to indulge in flights of fantasy or wild imagi nation about future possibilities; most journal editors will delete these.

Regulatory approvals Regulatory approvals Interventional clinical or device trials are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Researchers are encouraged to use an existing and established international register such as ISRCTN or ClinicalTrials.gov to ensure that the public is aware of a trial before recruitment of the first participant. Trials involving sites specifically in EU countries must be registered in the EU Clin ical Trials Register. Trials should be registered before applying to the MHRA for a clinical trial authorisation via the MHRA submissions portal and researc hers must ensure that the registry is kept up to date and trial results are uploaded in the appropriate timeframe. This can be a complicated and trying process, and support should be sought from the investigators’ employing institution. Editors of the major surgical journals now agree that all clinical trials should have been registered before an article relating to a trial can be published.

A confi - dence interval that includes zero usually implies a lack of sta - tistical significance. Scientists usually employ probability ( P -values) to describe statistical chance.

It is important not to forget that P /uni00A0 = /uni00A0 0.05 - simply means that there is only a 1:20 chance that the di ff er - ences between the variables would have happened by chance when in fact there is no real di ff erence.

Confidence intervals are the best guide to the possible - range in which the true di ff erences are likely to lie. A confi - dence interval that includes zero usually implies a lack of sta - tistical significance. Scientists usually employ probability ( P -values) to describe statistical chance. A P -value <0.05 is commonly taken to imply a true di ff erence. It is important not to forget that P /uni00A0 = /uni00A0 0.05 - simply means that there is only a 1:20 chance that the di ff er - ences between the variables would have happened by chance when in fact there is no real di ff erence. If enough variables are .niaid. examined in any study , significant di ff erences will occur simply , 1915–2007, Ohio State University , OH, USA, published their seminal paper more sophisticated analysis to determine the significance of individual risk factors. Univariable or multivariable logistic regression analysis techniques may be appropriate. Statistics simply deal with the chance that observations between populations are di ff erent and should be treated with caution. Clinical results should show clear di ff erences. If sta tistics are required to demonstrate di ff erences betw een results, it is likely that they are unlikely to have major clinical signifi cance.

Sample size Sample size Calculating the number of patients required to perform a satis - factory investigation is an important prerequisite to any study . An incorrect sample size is probably the most frequent reason for research being invalid. Often, surgical trials are marred by the possibility of error caused by the inadequate number of patients investigated. none (false positive). /uni25CF Type II error . Benefit is missed when it was there to be found (false negative). Calculating the number of patients required in the study can overcome this bias. Unfortunately , it often reveals larger number of patients is needed for the study than can pos sibly be obtained from available local resources. This usually means expanding enrolment by running a multicentre study – which has the added benefit of improving the external validity of findings. More patients will need to be randomised than the final sample size to take into account patients who die, drop out or are lost to follow-up; this is known as the attrition rate. A longer time from trial entry to primary outcome assessment will result in an increased attrition rate of participants. The following is an example calculation for a study to recruit patients into two groups. In order to calculate a sam ple size, it is now common practice to set the level of pow for the study at 90% with a 5% significance level. This means that, if there is a di ff erence between study groups, there is a 90% c hance of detecting it. Based on previous studies, realistic expectations of di ff erences between groups (i.e. the magnitude of the e ff ect seen from utilising the intervention under study), according to the best available evidence, should be used to cal culate the sample size. The formula below uses the results of a reduction in event rate from 30% to 20% (e.g. a new treatment expected to reduce the complication rate such as wound infec tion from 30% = r to 20% = s ). [ r (100 − r ) + s (100 − s )] 9 × 2 ( r − s ) [30(100 − 30) + 20(100 − 20)] e.g. 9 × 2 (30 − 20) = 333 needed in each group Sample size Calculating the number of patients required to perform a satis - factory investigation is an important prerequisite to any study .
