Evidence for Nursing: new evidence and resources – March 2022

The latest evidence and resources for nurses and clinical support staff. You can either scroll through this page or click on any of the links below to jump to the relevant section.

Please note, unlike the rest of our blogs, our Evidence for Nursing: new evidence and resources blogs will not be updated.



This year, Cochrane is continuing to produce new and updated reviews in response to the pandemic. We have blogged about many of them and this blog COVID-19 evidence: a Cochrane round-up brings together a large collection of evidence and resources, starting from when this evidence was first being produced in spring 2020. Plus, we have two blogs on COVID-19 treatments: 1) Treatments for mild COVID-19 and 2) Treatments for moderate to severe COVID-19: Cochrane evidence. Like the reviews themselves, all our blogs are updated to reflect new evidence.

School nurses in particular may be interested in this Featured Review Measures implemented in the school setting to contain the COVID-19 pandemic: a rapid review (January 2022). There is also a Cochrane Clinical Answer Do measures implemented in the school setting help contain the COVID‐19 pandemic? 

Cochrane Special Collections

Cochrane Special Collections bring together a collection of Cochrane Reviews on important topics for the prevention and treatment of COVID-19. They are developed with experts from our global Cochrane network. They are based on World Health Organization interim guidance, and continuously updated. You can find Coronavirus (COVID-19) Special Collections here. Those updated in January 2022 include Coronavirus (COVID-19): evidence relevant to critical care and Coronavirus (COVID-19): infection control and prevention measures.

Cochrane Podcasts

Cochrane COVID-19 podcasts offer short summaries of Cochrane COVID-19 reviews from the authors themselves. A good way to hear the latest Cochrane evidence in under 5 minutes each. Podcasts released in January 2022 include:

Cochrane Clinical Answers

Cochrane Clinical Answers (CCAs) provide a readable, digestible, clinically-focused entry point to rigorous research from Cochrane Reviews. They are designed to be actionable and to inform point-of-care decision-making. Each CCA contains a clinical question, a short answer, and data for the outcomes from the Cochrane Review deemed most relevant to practising healthcare professionals.

You can find Cochrane Clinical Answers related to COVID-19 here.

Care of the newborn, including preterm infants

Continuous glucose monitoring for the prevention of morbidity and mortality in preterm infants

The Cochrane Review Continuous glucose monitoring for the prevention of morbidity and mortality in preterm infants (December 2021) highlights an evidence gap, with the effects of continuous glucose monitoring (CGM) on preterm infant mortality or morbidities remaining uncertain.

Cuffed versus uncuffed endotracheal tubes for neonates

The Cochrane Review Cuffed versus uncuffed endotracheal tubes for neonates (January 2022) has highlighted an evidence gap on the benefits and harms of cuffed (inflated or non-inflated) endotracheal tubes (ETTs) compared with uncuffed ETTs for respiratory support in neonates.  

Feeding intervals for bolus feeding in very preterm infants

Cochrane Clinical Answer: How do short feeding intervals compare with long feeding intervals for bolus feedings in very preterm infants?

Cochrane Clinical Answer: How do opioids compare with placebo/no treatment for newborn infants receiving mechanical ventilation? 

Indomethacin for treating symptomatic patent ductus arteriosus (PDA) in infants

Cochrane Clinical Answer: What are the benefits and harms of indomethacin for treating symptomatic patent ductus arteriosus (PDA) in infants? 


Chronic obstructive pulmonary disease (COPD)

Podcast: Integrated disease management for people with chronic obstructive pulmonary disease.



Podcast: Omega-3 fatty acids for depression in adults 


Hip fracture

Following the publication of a suite of Cochrane Reviews, you can read this Interview with authors of Hip Fracture reviews and from there link to the reviews themselves.


Low-carbohydrate versus balanced-carbohydrate diets

 A Cochrane Review Low‐carbohydrate versus balanced‐carbohydrate diets for reducing weight and cardiovascular risk (January 2022) has found that, both in people with and people without Type 2 diabetes:

  • “There is probably little to no difference in the weight lost by people following low-carbohydrate weight-reducing diets (also known as ‘low-carb diets’) compared to the weight lost by people following balanced-carbohydrate weight-reducing diets, for up to two years.
  • Similarly, there is probably little to no difference between the diets for changes in heart disease risks, like diastolic blood pressure, glycosylated haemoglobin (HbA1c, a measure of blood sugar levels over 2-3 months) and LDL cholesterol (‘unhealthy’ cholesterol) up to two years.”

You can read more about it in this article Featured review: Low-carbohydrate versus balanced-carbohydrate diets for reducing weight and cardiovascular risk.


Patient-reported outcome measures feedback

Cochrane Clinical Answer: How does feedback to people receiving care and/or healthcare professionals of patient‐reported outcome measures (PROMs) impact outcomes of care? 


Pressure ulcer prevention

Cochrane Clinical Answer: How do alternating pressure (active) air surfaces compare with other surfaces for preventing pressure ulcers? 


Preventing deep vein thrombosis and pulmonary embolism after surgery

Cochrane Podcast: Are inflatable sleeves and medication effective to prevent deep vein thrombosis and pulmonary embolism after surgery? 


Smoking cessation

The bottom line of the new Cochrane Review Heated tobacco products for smoking cessation and reducing smoking prevalence (January 2022) is that “heated tobacco probably exposes people to fewer toxins than cigarettes, but possibly more than not using any tobacco.” “No studies reported on cigarette smoking cessation, so the effectiveness of heated tobacco for this purpose remains uncertain.”



Cochrane Clinical Answer: For adults post stroke, how does more time spent in rehabilitation impact outcomes? 


Trial recruitment

Challenging  misinformation

In this free Lifeology course, you can learn what you can do to slow and prevent the spread of misinformation: What is an infodemic and how can we prevent it?: a Lifeology and Cochrane collaboration. 

Trusted information needs to be protected on social media as much as misinformation needs to be challenged. Read about the recent removal of Cochrane’s Instagram post and shadowban which highlight the realities of Cochrane’s call against misinformation.

Call to action

Millions of lives could be saved if health evidence and communication is put at forefront of pandemic preparedness. The New Cochrane Convenes report recommends urgent action among those who fund, generate and use evidence to ensure the world is better prepared.

In a call to action, Cochrane is “encouraging other organizations who produce, use, fund or communicate about evidence to join us and support the call to action as a way of helping spread the recommendations further and acting on them”.

“If you lead or are part of an organization, please consider supporting the call to action, or encourage leadership to do so. If you are not affiliated with an organization, you can help by asking your local political leaders, research funders and institutions to support the call to action and by spreading the recommendations.”
