Auto-translate said:National Board of Health and Welfare rejects WHO evidence base on post-covid
Despite widespread criticism, the National Board of Health and Welfare will not update its knowledge base on post-infectious conditions.
‘Perhaps the most serious thing is that they do not recognise the WHO's red flags,’ infectious disease physician and researcher Judith Bruchfeld told F&F.
The National Board of Health and Welfare's knowledge support on post-infectious conditions was presented in August this year and was heavily criticised by doctors, researchers and patient associations - who felt it did not take sufficient account of new knowledge in the field.
The knowledge support was commissioned by the government and aims to help primary care physicians choose the right interventions when complications arise after infections. It covers the diagnoses post-covid, post-influenza, post-sepsis, post-intensive care syndrome, ME/chronic fatigue syndrome and PANS/Pandas (neuropsychiatric disorders).
Evidence is lacking according to the National Board of Health and Welfare
In the support, the National Board of Health and Welfare writes that there is no ‘evidence-based way’ to treat and rehabilitate the patient group. The advice given is mostly about relieving symptoms.
Judith Bruchfeld, a researcher at Karolinska Institutet and a specialist in infectious diseases at Karolinska University Hospital in Solna, agrees that there is a lack of good treatment studies in the field.
- ‘But that's not surprising, as the underlying mechanisms behind the diseases are still being discussed,’ she says.
However, Bruchfeld believes that there are plenty of well-designed studies based on clinical experience.
These include observational studies examining subgroups of post-COVID patients, or studies describing how the sequelae of COVID-19 can be diagnosed, alleviated and rehabilitated.
Red flag for physical exercise
The National Board of Health and Welfare's advice that patients with post-infectious symptoms can be offered rehabilitation in the form of gradually increasing physical activity was particularly harshly criticised.
This is despite the fact that, for example, the WHO in its clinical guidelines for COVID-19 shows red flags to warn doctors against recommending physical exercise for conditions such as exercise-induced low oxygenation or exercise-induced heart problems. The latter include POTS syndrome, which causes a sharp increase in heart rate when sitting or standing up.
The National Board of Health and Welfare's advice may therefore pose patient safety risks in some cases, according to critics.
- This is serious because, according to the WHO, doctors must rule out the possibility that the patient has suffered dangerous complications from COVID-19 before giving advice on physical exercise,’ Judith Bruchfeld told F&F.
Lisa Norén, a doctor and spokesperson for the Swedish Covid Association, also calls for more information in the knowledge support.
- ‘The National Board of Health and Welfare should include the WHO's red and also the yellow warnings,’ says Lisa Norén.
‘The red flag means a strong recommendation and the yellow a limited recommendation.
Judith Bruchfeld also calls for knowledge about how POTS can be diagnosed, and for doctors to be recommended to investigate respiratory problems such as dyspnoea before starting rehabilitation. This is because breathing problems may be due to chronic pulmonary embolisation or hypoxia due to impaired gas exchange in the lungs, she says.
National Board of Health and Welfare: no need for revision
In early November, Judith Bruchfeld and Lisa Norén, among others, met with representatives of the National Board of Health and Welfare to discuss the support. The agency's director general, cardiologist Björn Eriksson, also attended. At the meeting, they were told that there will be no revision of the knowledge support at present. Something that Sofia von Malortie, head of unit at the National Board of Health and Welfare, confirmed to Forskning & Framsteg.
During the meeting, the Swedish Covid Association criticised the fact that the National Board of Health and Welfare does not rely on international bodies such as the WHO or the US National Institute for Health and Care Excellence (NICE).
- The National Board of Health and Welfare's representatives stated that their ambition was to look at international sources of knowledge, but that they could not assess the WHO's evidence base, for example,’ says Lisa Norén.
National Board of Health and Welfare rejects WHO warnings
According to the Swedish Patient Act, healthcare professionals must carry out their work in accordance with both science and proven experience. Sofia von Malortie at the National Board of Health and Welfare says that the agency used the GRADE evidence grading scale to determine whether there is scientific support for recommending different medical interventions.
However, as the WHO's red warning flags are based on experts' proven experience, and as the WHO has not used GRADE, the National Board of Health and Welfare considers that the assessments have a weak evidence base.
‘We chose not to make recommendations based on such a basis, but instead to provide guidance by encouraging the recipient to make their own assessments and follow up their efforts,’ writes Sofia von Malortie in an email to Research & Progress.
In practice, this means that the National Board of Health and Welfare rejects the WHO's red flags. This is despite the fact that the WHO clearly states its evidence base in its guidelines under the heading ‘Justifications’ and provides a number of scientific references.
- Unless the evidence base is updated, it may be difficult for primary care doctors to diagnose serious complications and decide on the best course of action, including the need for referrals to secondary and tertiary care, says Judith Bruchfeld.
