The Cerberus of science – dealing with ethics committees

We asked a colleage, Hannah Rosebrock, to write a blog for us, thank you Hannah.

In Greek mythology, Cerberus guards the gate of the underworld to prevent the dead from leaving. In social and clinical science, this role is fulfilled by ethics committees who stand as guardian between researchers and Cerberusparticipants and prevent the latter to be exploited by the former for the sake of science. The role of the Cerberus is a necessary one – although not very flattering, Cerberus is depicted as a three-headed beast. In the context of ethics committees, its three heads are called bureaucracy, officialdom and inefficiency.

According to the National Health and Medical Research Council (NHMRC) there are more than 200 HRECs operating in organisations and institutions throughout Australia (find a list of human Research Ethics Committees registered with NHMRC here). Although all HRECs base their decisions on the same principles deprived from the same National Statement on Ethical Conduct in Human Research, every HREC has its own application procedures, forms and processes. Further, gaining approval from one ethics committee is no vouch for approval from another ethics committee.

This lack of standardisation specifically affects multi-site projects which led to the founding of the National Mutual Acceptance Scheme (NMA) in 2013. Under the NMA scheme, multi-site research projects do not have to gain ethics approval from every site the project is conducted at but only once, from a NMA certified HREC. As of August 2017 the scope of the NMA scheme covers all human research conducted at a public health organisation in Queensland, New South Wales, the Australian Capital Territory, Victoria, South Australia, and – the latest addition to the scheme – Western Australia. Note: Northern Territory, Tasmania, and private health organisations are not included in the NMA scheme. Still, you might be tempted to think, that the NMA scheme has de-bureaucratised the ethics application process, and to some extent, this is true. There is certainly less duplication (if you don’t count private health organisations, Northern Territory and Tasmania). However, researchers are still fighting with a lack of standardisation, as every state has multiple NMA certified HRECs[1] and application procedures vary between and within states. This multitude in ethics committees, applications processes and forms, seems unnecessarily confusing, given that they are all assessed and certified by the same body (the NHMRC) for their compliance with the same criteria based on the same National Statement of Responsible Conduct in Human Research.

Independent of the HREC approval, researchers have to seek approval from the relevant Research Governance office (RGO) for each site the project is conducted at. There is no such thing as a mutual acceptance scheme for research governance approval, every site has its own assessing criteria for determining the site’s suitability for conducting a given research project. This adds to the generally labour-some and tedious process of gaining ethics approval.  In terms, this uses resources, and most commonly tax payer funded resources. In one Australian study, the cost of obtaining ethics and relevant approvals was $348,000 or 38% of study budget.

Applications for HREC approval are often no less than 63 pages; applications for Research Governance approval encompass about 23 pages – exclusive the extensive supporting documentation required, which can be up to another 150+ pages. Applications to both, HREC and RGO’s vary, with some still requiring submission in hardcopy by snail-mail, (additionally to email, USB and online forms) and will only be assessed, once received in hardcopy. This method is unnecessarily prone to error. To simplify, you must take steps away, rather than adding additional steps. The entire process is so focussed on detail that researchers, as well as assessing HREC and RGO officials can’t see the wood for the trees anymore. So much information is requested that even low-risk research projects that involve none to minimal involvement with participants, and thus hardly justify the use of the term ‘participants’, seem to turn into a second Stanford prison experiment throughout the process.

#A Trawl for Trends

In the lead up to the ACIPC conference in Canberra next week, I thought it might be timely to write something about the use of Twitter at infection control conferences. Thanks to Gabby Milgate for assisting with this blog.

Some of you might know that last year, a group of us reviewed tweets from four infection control/ID conferences – UK Infection Prevention Society, ID Week2016, The Federation of Infectious Society/Hospital Infection Society and the Australasian College for Infection Prevention and Control. Read the article here . 

Twitter as a medium for infection control content has grown from 181 Tweets at IPS2011 to 11,457 tweets at IPS2016. This rapid growth seems to suggest the twitter epidemic is contagious! The analysis of tweets from these four conferences identified trends in conference-related twitter activity.

Here are some evidence-based trends to help your infection prevention tweeimagests fly!

  1. Tweets with web-links are more likely to be retweeted, all things considered
  2. Picture are out – these are less likely to be re-tweeted, all things considered
  3. Tweeting on topics such as ‘Cleaning’, “Media@, ‘Clostridium Difficile’, ‘Antiseptic’, ‘Infection prevention and control’ and ‘Hand hygiene’ are more often retweeted.

I’ll be talking more about this at the ACIPC conference next week – the abstract is here

Not only has Twitter been used to broaden conference exposure and encourage attendees to further engage with content but the Royal Society of Chemistry hosted an entire conference on Twitter. The conference had an audience of 380,000 online users, without a ‘face-to-face’ component.  The conference was both cost-effective and far-reaching.  Additionally, its virtual delivery eliminated risks of airborne or droplet transmission of infections!

Twitter may serve as a useful tool for infection control professionals and enthusiasts to broaden their networks, providing a platform for infection related discourse and a mode of communication for health promotion and education to the general public of social media users.

Perhaps a future trending topic: ‘Twitterer’s twiddling their thumbs on their devices practice excellent hand hygiene’.

Australian HAI point prevalence survey – update

As you might know, I am leading a team of investigators to conduct the first national HAI point prevalence survey in Australia in over 30 years.

We are grateful to have received so many expressions of interest from hospitals across Australia. Of course if we had endless resources we would survey all hospitals, however as you would appreciate, we have limited funding, and therefore are focussing on 20 public hospitals classified as either Principal Referral or Group A hospitals (AIHW peer group).

Data collection in our study will be undertaken by two trained research assistants, who will collect data from each participating site. This will avoid the burden of data collection  from hospital resources, and importantly add consistency to application of definitions and data collection processes (a current gap in Australian HAI surveillance).

On top of HAI data, we are also looking to estimate device usage and explore some issues around single rooms and MRO’s, and so have developed some secondary objectives specific for these.

Primary objectives

  1. To estimate the total prevalence of HAIs among inpatients aged ≥18 in public acute care hospitals in Australia
  2. To describe the HAIs by site, type of patient, specialty, type of facility and geographical location

Secondary objectives

  1. To determine the prevalence of patients:
    • managed under transmission based precautions isolation in a single room
    • with an indwelling urinary catheter device
    • with vascular access device(s)
    • with a multi drug resistance organism (infection or colonisation)

Ethics submission is close, and we are working hard on ensuring this is processed efficiently so we can turn our attention to Site Specific Assessments and Research Collaborative Agreements.

Finally a welcome to Bridey Saultry who will be commencing soon as Project Manager for our study. Bridey will be working with us half time to ensure we keep on track with this exciting study.

Outside the box: Infection prevention beyond the hospital walls

The recent article published in the MJA by Agostino and colleagues from the Hunter New England area provided data that could be described as not so startling, but nevertheless alarming. Their study aimed to identify groups at risk of MRSA infection, as well as the proportion of patients with MRSA but no history of recent hospitalisation (previous 12 months).

In their large cohort, they found that “young people, Indigenous Australians, and residents of aged care facilities, are disproportionally affected by CA-MRSA infections”.

Two comments in their Discussion caught my eye. The authors call for:

  • the focus of control measures to move from the healthcare setting to the community
  • national surveillance of MRSAphotodune-598972-think-outside-the-box-xl

The results of this study are not so startling because the findings are consistent with previous studies, alarming because this is another piece of evidence highlighting the deficits of our local knowledge.

This brings me to my next point. I am excited to be part of a team conducting a large study exploring infection prevention in Australian residential and aged care facilities. Led by Prof Brett Mitchell, together with Prof Ramon Shaban and Dr Deborough MacBeth, we aim to mimic a recent program of work  that generated so much rich information about infection prevention in our hospital facilities. Here are links to a sample of some of papers from this work:

This cross sectional study aims to explore governance, education, practice, surveillance and competency and capability – five key domains relating to infection prevention and control. All aged care homes in Australia are in the process of being contacted.

The findings of this study will be significant, they will:

  • further support ACIPC to refine the role and scope of practice of ICPs and better target education strategies,
  • inform decision-makers faced with accessing and planning infection control resources in settings outside hospitals.
  • guide future research priorities in this area
  • understand priorities and gaps in infection control services

If you receive an invitation to participate, I strongly encourage you to do so.

We look forward to sharing our findings with you during 2018.

Not peeling grapes…

Standard 3.2.1 of the The National Safety and Quality Health Service Standards in Australia states “Surveillance systems for healthcare associated infections are in place”.

If I could wave the magic wand, the standard I woulrainbow-star-magic-wand-6834-pd like to see would say something like this, “Electronic surveillance systems for healthcare associated infections are in place in alignment with the national surveillance program” (it’s a big wand).

It’s a fact that very few healthcare facilities have dedicated HAI surveillance software, which means that for much of it, surveillance continues to be a manual, labour intensive activity. Not only is this burdensome, we also know it influences data quality. Why don’t we all use electronic surveillance software (ESS)? Capital expenditure aside, maybe its because ICPs (and others) aren’t convinced of their value i.e. what effect does it have on day to day practice, how does it influence the overall infection prevention program?

In a recent systematic review published in the Journal of Hospital Infection, we sought to establish the impact of ESS on infection prevention. We were able to identify 16 papers in a search from 2006 to 2016. The review can be accessed here

DSC_0038-625x415

There was much variation in the studies, so it was difficult make any strong conclusions. However, we did find that every paper described a marked reduction in time taken to collect data and ascertain cases. This is clearly a good thing for the ICP collecting data, but I don’t suspect that saved time is spent sitting around peeling grapes. Its possible that the ESS allowed them to broaden their surveillance activities, provide more accurate and better quality data, respond to outbreaks quicker, undertake local research projects,  enable more detailed reports for the clinicians (and less detailed dashboards for their Executives), not to mention standardise data for public reporting and informing the build of algorithms for greater efficiency.

Unfortunately we cant really be sure how an ESS influences (benefits) infection prevention because we don’t have the data. As we conclude in our paper, we need specific research exploring the effect of ESS on infection prevention as a primary outcome, and whether this has any impact on infection and /or patient outcomes.

It would be very interesting to know if any hospitals with ESS have explored this issue, or if those who are moving towards implementing an ESS have considered some metrics around the benefits.

Variation in hospital cleaning

Hospital cleanliness has a number of implications for patients and staff in addition to simply preventing the spread of infection. Aside from infection, for patients and their families, a tidy and sanitary ward greatly improves comfort and provides assurance of the quality of their treatment. For staff, a hygienic environment means a more appealing workplace.

Throw in numerous studies demostrating and articulating links between the environment and infection [1-5], it’s easy to see why effective cleaning is of utmost importance when it comes to maintaining safe and quality hospital care. In light of this, it is difficult to believe that we have no uniformity across Australian hospitals when it comes to cleaning practices, staff training, products used or even standards by which to evaluate whether a hospital environment is clean and safe.

Variation in hospital cleaning practice and process in Australian hospitals: a structured mapping exercise [6] is the first paper to identify the variations in cleaning practices present among Australian hospitals. It describes in detail a range of discrepancies found in cleaning processes used across the country, in a study of 11 private and public Capturehospitals.

This paper is the latest from The ‘Researching Effective Approaches to Cleaning in Hospitals’ (REACH). The REACH study uses a bundle of standardized interventions in an attempt to combat healthcare-associated infections, with a view of gathering evidence that could be used to inform better and more standardized cleaning methods in the future.

The variation in cleaning practice and processs highlighted in this paper, demonstrates  the need for nationally recognised standards in hospital cleaning and outlines the challenges associated with the current system – or lack thereof.

The burden of HAIs in Australia

Today, we published an article in Infection, Disease and Health estimating the number of HAIs occuring in Australia each year. [1]

To do this, we undertook a systematic review of the peer reviewed literature between 2010 and 2016. We identified 24 articles that reported the incidence of HAIs in Australian hospitals.

Overall, data from these multi centred studies suggested 83,000 HAIs per year in Australia. UTIs are were the most common, followed by C.difficile, SSIs, respiratory infections and Staphylococcus aureus bacteraemia. HAI burden.png

Of course, these numbers are a very  large underestimate given the lack of or incomplete data on common infections. It is also limited to data published in the peer reviewed literature.

Incidence data on infections such as pneumonia, gastroenterological and bloodstream infections (other than SAB) were not identified, thus potentially
missing up to 50% of infections. That being the case, the

PPS blog incidence of HAIs in Australia may be closer to 165,000 per year.

Don’t believe me? Have a look at the results of point prevelance studies in Europe (right). Respiratory tract infections, bloodstream infections and others account for a large proportion of HAIs.  Of course, Australia has not had a PPS undertaken in 30 years, so we don’t really know. However, for readers of this blog, you will know that will soon change.

A figure of 200,000 HAIs per year in Australia is commonly cited, however, this figure was derived from one study undertaken several years ago (a sign of what was available at the time). Our study, may, in part, demonstrate the increasing number of publications on HAIs in Australia. We are certainly not suggesting a reduction in HAIs and any such claim based on the findings of our study should be immediately dismissed.

There are some other equally important findings from our study:

  • There needs to be a determination and action by state and national government bodies to achieve consensus on national HAI definitions
  • We need national approaches to HAI surveillance and transparent regular reporting. Australia is so far behind other countries in this regard [2] [3]
  • In the absence of action by government, we call on those undertaking HAI surveillance (especially incidence) to report your data in the peer reviewed literature

We also found there is little information about healthcare associated respiratory infections, such as pneumonia. Maybe it is in the too hard basket (nice blog by Martin Keirnan which says it all). Well, I think we should do something about healthcare associated pneumonia – at the very least, understand the incidence and risk factors a little better. I am working on it…..
