COVID-19 research has overall low methodological quality thus far: case in point for chloroquine/hydroxychloroquine
|
This article examines recent hydroxychloroquine-azithromycin research, and finds that it is underpinned by very low-quality methodology. The authors, who include researchers from Health Research Methods, Evidence and Impact and the GUIDE Research Methods Group at McMaster University, consider the overall body of recent COVID-19 research to be unreliable. Flawed methodology and sub-optimal reporting of research findings could lead to biased estimates of effect. This could lead to substandard treatment decisions, and may be detrimental to patients. The article provides specific suggestions for improving on COVID-19 research methods and reporting, with a focus on issues that researchers must consider in their methodology and reporting if we are to have confidence in the estimates of effect.

Surviving Sepsis Campaign: Guidelines on the management of critically ill adults with COVID-19
|
A panel of 36 experts from 12 countries, proposed 53 questions relevant to the management of COVID-19 in critically ill patients in the ICU. All panel members completed the World Health Organization conflict of interest disclosure form. They identified relevant and recent systematic reviews on most questions relating to supportive care. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. The panel then generated recommendations based on the balance between benefit and harm, resource and cost implications, equity, and feasibility. Recommendations were either strong or weak, or in the form of best practice recommendations. No recommendation was provided for the following topics: infection control, laboratory diagnosis and specimens, hemodynamic support, ventilatory support, and COVID-19 therapy. When available, the panel will provide new recommendations in further releases of the guidelines.

How safe are library books?
|
Current research says that in ideal lab conditions, the COVID-19 virus can survive for up to 24 hours on cardboard and up to 2-3 days on plastic and stainless steel. We want to help you stay safe in the library – so we’ve implemented book quarantines, social distancing, and regular cleaning of surfaces such as tables, door handles and computer keyboards and mice.

COVID-19: get the latest research
|
Coronaviruses are important human and animal pathogens. At the end of 2019, a novel coronavirus was identified as the cause of a cluster of pneumonia cases in Wuhan, a city in the Hubei Province of China. It rapidly spread, resulting in an epidemic throughout China, with sporadic cases reported globally. In February 2020, the World Health Organization (WHO) designated the disease COVID-19, which stands for coronavirus disease 2019. Previously, this virus was referred to as 2019-nCoV.
The COVID-19 update presented to interns on 11 March 2020 is now available via the Library website. Presenters included: Dr Tony Merritt (Public Health Physician, Population Health), Dr Catherine Berry (Staff Specialist, Immunology and Infectious Diseases Unit, JHH), and Assoc Prof Chris Grainge (Staff Specialist, Respiratory and General Medicine, JHH)

MJA RESEARCH SKILLS – Stepped wedge cluster randomised trials
|
The basic premise of a stepped wedge cluster randomised trial (SW-CRT) is that all clusters start in the control condition, and they switch to the intervention condition in an order determined by randomisation. SW-CRTs differ from cluster crossover trials in that the switch is only in one direction, from control to intervention condition.

The health effects of fine particulate air pollution (bush fire smoke)
|
Short term exposure to fine particulate matter with diameter less than 2.5 µm (PM2.5) - bush fire smoke - has previously been associated with increased risk of mortality and hospital admissions due to cardiovascular and respiratory diseases, diabetes mellitus, neurological diseases, and deep vein thrombosis. A recent US study published in the BMJ, including data from 95,277,169 participants (aged 65 or older admitted to hospital), found short term exposure to PM2.5 was also positively associated with risks of several prevalent but rarely studied causes of hospital admissions, such as septicemia, fluid and electrolyte disorders, and acute and unspecified renal failure. These associations remained even at a daily PM2.5 concentration below the WHO 24 hour guideline. Substantial economic costs were linked to a small increase in short term PM2.5.

Telephone-delivered CBT can provide lasting benefits for people with IBS
|
This NIHR-funded study published in the Lancet is the 24-month follow-up to an earlier publication of 12-month outcomes for 558 people with irritable bowel syndrome (IBS) receiving usual care alone or additional telephone or web-based cognitive behavioural therapy (CBT). The former paper showed that both therapies helped people deal with their IBS. This longer-term follow-up shows that CBT continues to benefit patients months after therapy sessions have stopped. IBS can be a very debilitating and difficult condition to treat. The present study helps strengthen the case for the provision of remote talking therapies, particularly telephone-based therapy (71% of study participants experienced a clinically significant improvement in their IBS symptoms), as a way to improve access and outcomes for patients.

Diagnosis and management of Guillain-Barre Syndrome in 10 steps
|
Guillain–Barré syndrome (GBS) is a rare, but potentially fatal, immune-mediated disease of the peripheral nerves and nerve roots that is usually triggered by infections. The incidence of GBS can therefore increase during outbreaks of infectious diseases, as was seen during the Zika virus epidemics in 2013 in French Polynesia and 2015 in Latin America. Diagnosis and management of GBS can be complicated as its clinical presentation and disease course are heterogeneous, and no international clinical guidelines are currently available. To support clinicians, the authors have developed a globally applicable guideline for the diagnosis and management of GBS. The guideline, published in Nature reviews. Neurology, is based on current literature and expert consensus, and has a ten- step structure to facilitate its use in clinical practice.

How long does a hip replacement last?
|
Total hip replacement is a common and highly effective operation. All hip replacements eventually fail if in-situ long enough and it is important that patients understand when this might happen. This meta-analysis published in the Lancet, included 44 case series that reported long-term outcomes of 13,212 hip replacement procedures. The authors also carried out a meta-analysis of data taken from national joint replacement registries in Australia and Finland. These provided 215,676 procedures, with outcomes at 15, 20 and 25 years. After 15 years, 89.4% of hip replacements had survived (data from Australian and Finnish registries). After 25 years, 57.9% were still intact (but data only available from the Finnish registry).

Reducing the use of broad spectrum antibiotics may help to cut rates of hospital-acquired VRE
|
In a research letter published recently in the Medical Journal of Australia, researchers from John Hunter Hospital reported that a global shortage of piperacillin/tazobactam in 2017 had prompted the hospital to shift to the use of intravenous amoxicillin/clavulanate (IVAC). Researchers noted that the number of hospital-acquired cases of vancomycin-resistant enterococcus (VRE) almost halved, dropping from 191 in the 12 months before the shortage to 101 in the 12 months afterwards (down 47%). The rate of methicillin-resistant staphylococcus aureus (MRSA) also fell from 53 to 31 (down 42%), but this was not statistically significant.

Review of patient relevant outcomes of partial vs. total knee replacement
|
Partial (or unicompartmental) and total knee replacement are both viable surgical options for treating partial knee osteoarthritis, but most patients with this condition currently undergo total knee replacement. This recent study from the BMJ attempts to provide evidence to improve shared decision making. Partial knee replacement has several advantages over total knee replacement, including shorter time in hospital, fewer serious medical complications, lower mortality, lower deep infection rate, and better functional outcome. Revision surgery is less likely after total knee replacement, but reoperation for other causes occurs at the same rate for both procedures.

UpToDate Practice Changing Update: Use TAVI in patients with aortic stenosis and low surgical risk
|
In this recent Practice Changing Update from UpToDate, the authors recommend transfemoral transcatheter aortic valve implantation (TAVI) rather than surgical aortic valve replacement (SAVR) (Grade 1B evidence), for most patients with symptomatic severe aortic stenosis who are at low surgical risk. However, SAVR is preferred to TAVI for patients with one or more of the following features: bicuspid or unicuspid aortic valve, poor transfemoral access, severe left ventricular outflow tract calcification, or an adverse aortic root.

ICARUSS is superior to usual care in achieving best-practice recommendations for traditional risk factors, as well as behavioural and functional outcomes, in stroke survivors
|
Local authors undertook a double-blind randomized controlled trial (n=249) in three Australian cities, testing a new model that implements best-practice recommendations for risk factor management in stroke survivors who have been admitted to stroke units to prevent stroke recurrence, and discharged from hospital to return to their primary care physicians. The Integrated Care for the Reduction of Secondary Stroke (ICARUSS) model is a shared care, multifaceted integrated program that includes bidirectional feedback between general practitioner and specialist unit, education, and engagement of patient and carer in self-management with ongoing input from a multidisciplinary team.

Exercise prevents falls in older people living in the community

A recent Cochrane Review including 23,407 participants -
mostly women, average age 76, from across 25 countries – found high-certainty evidence that exercise programmes reduce the rate of falls and the number of people
experiencing falls in older people living in the community. Exercise programmes that reduce falls primarily involve balance and functional exercises,
while programmes that reduce falls include multiple exercise categories - typically balance and functional exercises, plus resistance exercises.

MJA RESEARCH SKILLS – Cluster randomised trials
|
Cluster randomised trials randomise groups of individuals, rather than individuals themselves, to interventions. The groups might be communities, schools, workplaces, hospitals, or patients treated by a particular doctor. There are a number of reasons for the use of cluster trials as opposed to individually randomised trials. They may be the only available choice, as when a city is randomised to a mass intervention. Another reason is that the investigators may wish to reduce the risk of contamination, or it may be more effective, more convenient or cheaper to deliver an intervention to a group rather than to an individual.

Clinical Practice Guideline for the management of Infantile Hemangiomas (aka strawberry birthmarks)
|
Infantile hemangiomas (IHs) occur in as many as 5% of infants, making
them the most common benign tumour of infancy. Most IHs are small, innocuous, self-resolving, and require no treatment. However, because of their
size or location, a significant minority of IHs are potentially problematic. This clinical practice guideline, published recently in Pediatrics
, defines those IHs that are potentially higher risk and discusses their specific growth characteristics. Early intervention (ideally by
1 month of age) is recommended. When systemic treatment is indicated, propranolol is the drug of choice. Topical timolol may be used to treat select
small, thin, superficial IHs. Surgery and/or laser treatment are most useful for the treatment of residual skin changes after involution.

Glucocorticoids for croup in children
|
The findings of this high quality Cochrane review
(n=4,565 children) reinforce current recommendations and practice with a moderate degree of certainty. They suggest that corticosteroids rapidly
reduce symptoms of croup in children, within about 2 hours and that the effect lasts for at least 24 hours. Corticosteroids included beclomethasone,
betamethasone, budesonide, dexamethasone, fluticasone, and prednisolone. Most studies compared corticosteroids to placebo, although some compared
them to adrenaline, to another corticosteroid, or combination of corticosteroids; or compared corticosteroids given in different ways, or amounts.
The findings may support earlier escalation of therapy. Shorter hospital stays and the reduction in readmission rates from about 20% to 10% are
important outcomes. Few studies had a low overall risk of bias, and many biases were unclear from the reporting. However, using the GRADE system
the certainty of evidence was thought to be moderate meaning that readers can be moderately confident in the effect estimate.

MJA RESEARCH SKILLS – Network meta-analysis in health care decision making
|
Network meta-analysis (NMA) represents an extension of pairwise meta-analysis that allows for the simultaneous comparison of three or more interventions
by considering both direct and indirect evidence. NMA provides an estimate of the relative effectiveness of all pairs of comparisons for both benefits and harms and represents the best way of deciding which available treatments
remain viable options and which should no longer be considered. The authors of this recent instalment of MJA Research Skills point out that all ranking interventions have limitations, and evaluation
of the certainty of evidence, using tools such as GRADE, is imperative.

This systematic review by Australian authors found moderate-quality
evidence that additional physical therapy services reduced length of stay by 3 days in subacute settings, and low-quality evidence that it
reduced length of stay by 0.6 days in acute settings. Published in Archives of physical medicine and rehabilitation,
the review also found that additional physical therapy led to small improvements in self-care, activities of daily living, and health-related
quality of life, with no increases in adverse events. There was no significant change in walking ability. Methodological quality was assessed
using the PEDro scale, and the GRADE approach was applied to each meta-analysis.

Laparoscopic cholecystectomy reduces the rate of major complications in high risk patients with acute cholecystitis – compared to percutaneous catheter drainage
|
The CHOCOLATE multicentre clinical superiority trial randomised high-risk patients
with acute calculous cholecystitis (APACHE II score of 7 or more) to either laparoscopic cholecystectomy or percutaneous catheter drainage. The trial was
concluded early after a planned interim analysis. This study, published in the BMJ, provides strong evidence that laparoscopic
cholecystectomy is superior to percutaneous catheter drainage in the treatment of high risk patients with acute calculous cholecystitis. Cholecystectomy not
only reduced the rate of major complications (ie, infectious and cardiopulmonary complications, or need for reintervention, or recurrent biliary disease), but also
reduced utilisation of healthcare resources and costs by more than 30 percent.

CLINICAL PRACTICE GUIDELINE: Atraumatic vs. conventional needles for lumbar puncture
|
Is the needle tip configuration important when performing a lumbar puncture
for any indication? A systematic review published in the Lancet earlier this year suggests that it is. The review – which
was highlighted in Health News (22.05.2018) – found that using atraumatic (pencil-point) lumbar puncture needles instead
of conventional lumbar puncture needles reduced the risk of post-dural-puncture headache and of return to hospital for additional pain control.
This BMJ clinical practice guideline, following GRADE methodology standards, makes a strong recommendation for the use of
atraumatic needles for lumbar puncture in all patients regardless of age (adults and children) or indication instead of conventional needles.

evidence supporting medical interventions and develop recommendations. Since then, the group has published a six-part series for clinicians
using GRADE guidelines, and a series of articles supporting systematic review authors and guideline groups using GRADE in their work. Over
100 organisations worldwide — including the World Health Organization, the Cochrane Collaboration, the Joanna Briggs Institute, the American
College of Physicians, DynaMed Plus and UpToDate — have endorsed or adopted GRADE.

Effect of aspirin on cardiovascular events and bleeding in the healthy elderly: ASPREE clinical trials
|
Aspirin is a well-established therapy for the secondary prevention of
cardiovascular events. However, its role in the primary prevention of cardiovascular disease is unclear, especially in older persons, who have
an increased risk. This trial published in the New England Journal of Medicine (NEJM) enrolled 19,114 community-dwelling
men and women in Australia and the United States who were 70 years of age or older and did not have cardiovascular disease, dementia, or disability.
9525 participants received 100 mg of enteric-coated aspirin, and 9589 received placebo. After a median of 4.7 years of follow-up, the rate of
cardiovascular disease was 10.7 events per 1000 person-years in the aspirin group and 11.3 events per 1000 person-years in the placebo group.
The rate of major haemorrhage was 8.6 events per 1000 person-years and 6.2 events per 1000 person-years, respectively.

MJA RESEARCH SKILLS – Survival studies: competing risks, immortality & censoring

If time is an integral part of a study, then a key issue is what else
happened to the participants during the time between their recruitment and the time at which we tried to record their outcomes. If we did not
find them, is that because they emigrated or died? If they died, was their death related to their original illness? Did they take some other
therapy in the interim? Time complicates all studies, but most complications can be managed by collecting detailed data on participants over
time and using survival analysis. Find out about survival analysis in this recent latest instalment of the MJA Research Skills series.

Increasing omega-6 fats reduces total serum cholesterol, but not other blood fat fractions or adiposity
|
This recent Cochrane review assessed the effects
of increasing omega-6 fats (linoleic acid, gamma-linolenic acid, dihomo-gamma-linolenic acid and arachidonic acid) on cardiovascular health, mortality,
lipids and adiposity, using previously unpublished data. 19 RCTs, including 6461 participants who were followed for one to eight years, were included.
The authors found no evidence that increasing omega-6 fats reduces cardiovascular outcomes other than myocardial infarction (MI) – where 53 people may
need to increase omega-6 fat intake to prevent 1 person from experiencing MI. High-quality evidence suggests increasing omega-6 fats reduces total serum
cholesterol, but not other blood fat fractions or adiposity.

identified 31 trials providing moderate to high-quality evidence. The benefits were small but could make a meaningful difference to the patient’s experience and
outcomes. Earlier mobilisation combined with less need for opioids and their associated risk of respiratory depression may have contributed to reduced risk of pneumonia.
