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. Like the reviews themselves, all our blogs are updated to reflect new evidence.
Cochrane Special Collections
Cochrane Special Collections assemble You can find Coronavirus (COVID-19) Special Collections here. 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. on important topics for the prevention and
Those updated in July include:
- Coronavirus (COVID-19): remote care through telehealth
- Coronavirus (COVID-19): infection control and prevention measures
- Coronavirus (COVID-19): evidence relevant to critical care
Cochrane COVID-19 Podcasts offer short summaries of Cochrane COVID-19 reviews from the authors themselves. A good way to hear the latest in under 5 minutes each.
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 from the Cochrane Review deemed most relevant to practising healthcare professionals. The evidence is displayed in a user-friendly tabulated format that includes narratives, data, and links to graphics. for the

Care of the newborn, including preterm infants
Early postnatal discharge from hospital
Cochrane Clinical Answer: What are the effects of early postnatal discharge from hospital for healthy mothers and term infants?
Opioid withdrawal in newborns
The Cochrane Review Opioid treatment for opioid withdrawal in newborn infants was updated in July 2021 with new trials added and conclusions changed.
Patent ductus arteriosus
Cochrane Clinical Answers:
- How does very early (within three days) treatment compare with expectant management of hemodynamically significant patent ductus arteriosus (PDA) in preterm infants?
- How does early (within 7 days) treatment compare with expectant management of hemodynamically significant patent ductus arteriosus (PDA) in preterm infants?
Tube feeding of preterm and low birth weight infants
The authors of a Cochrane Review Push versus gravity for intermittent bolus gavage tube feeding of preterm and low birth weight infants (August 2021) found a single small study with 31 infants and conclude that “we do not have sufficient evidence to determine the effects of intermittent bolus gavage feeding for preterm and low birth weight infants.”
The authors of the Cochrane Review Slow advancement of enteral feed volumes to prevent necrotising enterocolitis in very low birth weight infants (August 2021) found that “advancing enteral feed volumes slowly (daily increments up to 24 mL/kg) compared with faster rates probably does not reduce the risk of necrotising enterocolitis, death, or feed intolerance in very preterm or very low birth weight infants. Advancing the volume of enteral feeds at a slow rate may slightly increase the risk of invasive infection.”
The authors of the Cochrane Review Short versus long feeding interval for bolus feedings in very preterm infants (August 2021) conclude that “The low‐certainty evidence we found in this review suggests that there may be no clinically important differences between two‐ and three‐hourly feeding intervals. There is insufficient information about potential feeding complications and in particular necrotising enterocolitis. No studies have looked at the effect of other feeding intervals and there is no long‐term data on neurodevelopment or growth.”
Cochrane Clinical Answer: What are the effects of exercise‐based cardiac rehabilitation for adults after heart valve surgery?
Delirium is common in hospitalised patients. The authors of a Cochrane Review on Non‐pharmacological interventions for preventing delirium in hospitalised non‐ICU patients (July 2021) have concluded:
- “There is moderate‐certainty evidence regarding the benefit of multicomponent non‐pharmacological interventions for the prevention of delirium in hospitalised adults, estimated to reduce incidence by 43% compared to usual care.
- We found no evidence of an effect on mortality.
- There is emerging evidence that these interventions may reduce hospital length of stay, with a trend towards reduced delirium duration, although the effect on delirium severity remains uncertain.”

Dietary salt for people with chronic kidney disease
Dietary salt for people with chronic kidney disease
The authors of a Cochrane Review Altered dietary salt intake for people with chronic kidney disease (June 2021) found high certainty evidence that salt reduction reduced blood pressure in people with chronic kidney disease (CKD), and albuminuria in people with earlier stage CKD in the short‐term. They state that “if such reductions could be maintained long‐term, this effect may translate to clinically significant reductions in CKD progression and cardiovascular events. Research into the long‐term effects of sodium‐restricted diet for people with CKD is warranted.”

In a blog for nurses, Support surfaces for managing pressure ulcers: which to choose?, Chunhu Shi, a nurse and lead author of a Cochrane Overview Beds, overlays and mattresses for preventing and treating pressure ulcers: an overview of Cochrane Reviews and network meta-analysis, shares what the latest evidence tells us about support surfaces for managing pressure ulcers, and what we still don’t know.
Reducing sedentary behaviour in older adults
In a Cochrane news item Get up, stand up: new review looks at reducing sedentary behaviour in older adults the lead author of the review Interventions for reducing sedentary behaviour in community‐dwelling older adults (June 2021) discusses the findings.
Spatial neglect/inattention following stroke or adult brain injury
The authors of a Cochrane Review Non‐pharmacological interventions for spatial neglect or inattention following stroke and other non‐progressive brain injury (July 2021) have concluded that “no rehabilitation approach can be supported or refuted based on current evidence from RCTs. As recommended by a number of national clinical guidelines, clinicians should continue to provide rehabilitation for neglect that enables people to meet their rehabilitation goals. Clinicians and stroke survivors should have the opportunity, and are strongly encouraged, to participate in research.”
Urethral catheters – strategies for removal
The Cochrane Review Strategies for the removal of short‐term indwelling urethral catheters in adults was updated in June 2021. The authors conclude “There is some evidence to suggest the removal of indwelling urethral catheters late at night rather than early in the morning may reduce the number of people who require recatheterisation.
It appears that catheter removal after shorter compared to longer durations probably reduces the risk of symptomatic catheter‐associated urinary tract infection (CAUTI) and may reduce the risk of dysuria. However, it may lead to more people requiring recatheterisation. The other evidence relating to the risk of symptomatic CAUTI and dysuria is too uncertain to allow us to draw any conclusions.”
The review is one of several included in the blog Short-term catheterisation: considerations for best practice.
Based on evidence from systematic reviews, Cochrane Effective Practice and Organisation of Care (EPOC) has prepared three information leaflets for health systems planners and implementers involved in developing vaccine communication strategies. You can read more and find the leaflets in Communicating to the public about vaccines and using digital strategies to promote vaccine uptake: information for planners and implementers.
Venous leg ulcers
A Cochrane Review Compression bandages or stockings versus no compression for treating venous leg ulcers (July 2021) has found that:
- “If using compression bandages or stockings, people with venous leg ulcers probably experience complete wound healing more quickly, and more people have wounds completely healed.
- The use of compression bandages or stockings probably reduces pain and may improve disease‐specific quality of life.
- There is uncertainty about adverse effects, and cost effectiveness.”
