This shows the latest covid and pandemic articles as they are indexed, or click on the 'Best' tab to see the highest quality and most important articles – many of which have metajournal summaries.

If you want to stay up to date with the latest COVID-19 articles, make sure to follow the relevant coronavirus topics by clicking on the red topic tags at the top of the page. Relevant articles will then be included in your weekly metajournal email if you are a metajournal subscriber.

There are already over 1,000 peer-reviewed covid articles indexed.

If you are looking specifically for articles covering Personal Protective Equipment (PPE) in the time of covid, the PPE article index along with the "Anaesthesiology, Personal Protective Equipment (PPE) and COVID" collection, has you covered. 😷

Biased thinking in a time of COVID

The 2020 coronavirus pandemic for all it's horror and challenge, has highlighted certain uncomfortable truths about the human condition. One of these has been the impact of our cognitive short-comings: our difficulty understanding the non-linear and non-binary, and our susceptibility to cognitive biases.

Many of these problems led to missteps at the beginning of the pandemic response, and now early in the fight continue to impede our decisions. By better understanding these cognitive traps we can at least be more alert to our blind spots and alter our actions in response.

As early data seeped out of China in January, quickly followed by cases appearing in global travel hubs, many national governments along with their populations refused to acknowledge the pandemic threat. Even as Northern Italy's health system first bent then broke, surpassing China's own COVID death count a mere 47 days after Italy's first confirmed case, world governments continued to water-down the threat.

The importance of non-inferiority and equivalence

Three papers from the first BJA of the new decade highlight the importance of non-inferiority: protective ventilation strategies, dexamethasone for prolonging interscalene blocks, and high inspired oxygen and surgical site infections.

Although none investigated new questions, they all represent studies into areas of ongoing uncertainty. They are each a useful reminder that most perioperative interventions do not significantly improve outcomes, although the majority of these probably do not ever make it to publication.

Lung-protection and atelectasis

Généreux et al. investigated the atelectasis-preventing benefit of a common protective ventilation strategy (PEEP and regular recruitment manoeuvres). Notable not just because there was no difference in atelectasis after extubation, but because the use of ultrasound to measure atelectasis helped to better track the intraoperative and post-extubation changes between the intervention and control groups.

Small Changes & Protection: antihypertensives, cognitive decline and ischaemic preconditioning

Metajournal on Small Changes & Protection: antihypertensives, cognitive decline and ischaemic preconditioning

Three interesting articles that appeared in the past few months, all following a common theme of ‘protection with small changes’. Although only one is itself practice changing, together they challenge us to continue to look to how small practice changes may have significant protective and preventative effects in the lives of our patients.

Antihypertensives evening dosing

Hermida et al. (2019) published impressive results from the massive, 10-year Hygia Project, which randomised almost 20,000 patients to take anti-hypertensive medications at bedtime or awakening.

Not only did patients who took antihypertensives (of any class) in the evenings have better blood pressure control, they also received a 45% reduction in major cardiovascular outcomes, including CVD death, infarct, coronary revascularisation, heart failure and stroke!

Given that many critical care doctors briefly touch on the medications their patients are taking, a simple “you should ask your primary physician about when its best to take your blood pressure tablets” could have a disproportionately large impact on patient health.

The problem with Electronic Medical Records

Doctors spending too much time using computers and electronic medical records

It is not so much that all Electronic Medical Records are terrible, but rather that it is so close to true that the occasional net-positive EMR roll-out does not move the needle much on its own. The greater challenge is that the reasons why the EMR experience is so poor also make it unlikely that EMRs will get dramatically better in the short-term.

The root of the EMR problem, fundamental to their very nature, ensures that EMRs will get worse before they get better.

I'm yet to be impressed by a hospital-wide monolithic EMR – one that is intuitive to use, enhances safety and reduces clinician workload rather than adding to it. An EMR that offloads administrative burden from healthcare providers, and enhances authentic interactions with patients. Where are the truly efficient EMRs that are true improvements to the paper-based systems they replace?

“Show me an [EMR that] only triples my work and I will kiss [their] feet.” – House of God1

Many EMRs are frustrating and inefficient, though tolerable in a necessary-evil kind of way. Clinicians put up with the many small EMR-inflicted aggravations because of the promises made for improved safety, efficiency and lowered costs. Yet the modern EMRs of today have largely failed to live up to even these low-bar aspirations.2

  1. Shamelessly stolen and adapted from Samuel Shem's (Stephen Bergman) classic House of God

  2. I use ‘EMR’ (Electronic Medical Record) in the strictest sense here, meaning a system for managing medical records in a hospital or group of hospitals. In North America ‘EMR’ is sometimes used interchangeably with ‘EHR’ (Electronic Health Record) which is more accurately a population-wide record of health, such as Australia’s imperilled My Health Record. In this example the EHR is an aggregator of health summaries, not a hospital medical record. At a medical-practice level, it is more accurate to talk about ‘practice management software’ than EMRs.
