Recognizing and managing post-exertional malaise in primary care

Abstract:

Post-exertional malaise (PEM) is a syndrome characterized by a worsening of symptoms after physical, cognitive, or emotional exertion. It presents as increased fatigue, usually accompanied by other clinical symptoms, such as muscle pain or cognitive impairment. First described in patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), PEM is now recognized as a hallmark of post-infectious syndromes that have received increasing attention through the emergence of long COVID. PEM is a distinguishing symptom of these conditions, and its early detection and appropriate management are essential to prevent long-term functional decline of affected patients. This review describes the definition and clinical impact of PEM and summarizes current recommendations for its management.

Virtual reality education on myalgic encephalomyelitis for medical students and healthcare professionals: a pilot study

Abstract:

Introduction: Myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS) is a chronic condition which may be characterised by debilitating fatigue, post-exertional malaise, unrefreshing sleep, and cognitive difficulties. ME/CFS has significant negative impact on quality of life for those living with the condition. This may be exacerbated by a lack of knowledge within healthcare regarding the condition. Previous research has found that immersive virtual reality (VR) educational experiences within healthcare education can increase knowledge and empathy.

Methods: The present study employed a quasi-experimental pre-test-post-test design to investigate the impact of a short immersive VR educational experience on knowledge of ME/CFS and empathy for those living with the condition. The VR experience placed participants into a virtual scene which told real life stories of the experience of people living with ME/CFS and their families. 43 participants completed in this pilot study: 28 medical students and 15 primary care health professionals. Participants completed measures of knowledge of ME/CFS and empathy before and after engagement with the experience.

Results: A statistically significant increase was found for levels of knowledge (p < .001, d = 0.74) and empathy (p < .001, d = 1.56) from pre-VR experience levels to post-VR experience levels with a medium and large effect size, respectively. Further analysis revealed no statistically significant difference between baseline levels of knowledge of ME/CFS between healthcare professionals and medical students.

Discussion: The present study is the first to explore the use of this short immersive VR experience as an education tool within healthcare to increase knowledge of ME/CFS, and empathy for those living with the condition. Findings allude to the previously established lack of knowledge of ME/CFS within healthcare although promisingly the increases in knowledge and empathy found suggest that this immersive VR experience has potential to address this. Such changes found in this small-scale pilot study suggest that future research into the use of VR as an educational tool within this setting may be beneficial. Use of a control group, and larger sample size as well as investigation of retention of these changes may also enhance future research.

First insights from patients presenting with long/post-COVID syndrome in primary care: an exploratory report

Abstract:

Background: Following the global pandemic of coronavirus disease 2019 (COVID-19), the long COVID or post-COVID syndrome refers to a relatively complex novel clinical entity. We conducted this study to assess the primary epidemiological features, main symptoms, and comorbidities probably related to this syndrome in patients referred to our long/post-COVID primary care unit during the initial months of its operation.

Methods and material: This single-center prospective observational study was conducted between April 2022 and December 2022 and enrolled 71 patients (33 men, 38 women) who were examined due to persisting symptoms after recovering from COVID-19 infection, with the mean time of the first visit estimated at 3.12 ± 2.41 months from their acute COVID-19 illness. A thorough medical history, clinical examination, laboratory, and any other tests were performed on all patients when necessary.

Results: The most common symptoms of long/post-COVID reported were fatigue (63.4 %), a persistent cough (45.1 %), stress manifestations (42.3 %), arthralgia or myalgia (33.8 %), tachycardia (32.4 %), depression manifestations (29.6 %), exertional dyspnea (28.2 %), and sleep disorders (25.4 %). Hypertension (in about 40 %) and the presence of five or more symptoms during the acute COVID-19 illness (in approximately 52 %) could be regarded as factors increasing the long/post-COVID appearance. The long/post-COVID syndrome affects even patients not experiencing severe COVID-19 illness. Unvaccinated patients are at higher risk of severe COVID-19 (p =0.014), higher risk of hospitalization (p =0.002), and in higher need of respiratory support with high flow (p =0.017) when compared to vaccinated ones. Hospitalized patients appear to be older than outpatients (59 ± 12.42 vs 52.78 ± 11.48 years of age; p =0.032.

Conclusion: The long/post-COVID syndrome is an established clinical entity, and several clinical features, symptoms, and patient profiles have to be assessed from the initial medical contact in primary care to exclude early any other clinical conditions and offer guided therapeutic strategies to those patients.

Long COVID as a never-ending puzzle: the experience of primary care physicians

Abstract:

Background: Long COVID provides a new context in which primary healthcare needs to be reexamined, especially because it has health and social dimensions. The experiences of care for patients with long COVID and primary care physicians’ perceptions are an unexplored area.

Aim: To explore the experiences of Slovenian primary care physicians in management and treatment of patients with long COVID.

Design & setting: A qualitative interview study in Slovenian primary care was carried out between November 2021 and April 2022.

Method: Semi-structured interviews were held with physicians that had treated patients with long COVID until saturation was reached. Qualitative content analysis (QCA) was used to analyze the data collected.

Results: Seventeen participants were interviewed. Six categories were defined based on the coding process: the definition and symptoms of long COVID; social exclusion, sick leave, returning to the work environment, cooperation with rehabilitation centers and the importance of trust and good communication with the patient.

Conclusion: The study shows the experiences of Slovenian primary care physicians in the management and treatment of long COVID. The problems related to long COVID were divided into two groups: health problems and psycho-social problems. Slovenian physicians have the greatest problems with dealing with the patient’s ability to work. It was found that adequate communication and trust between physicians and patients are two important indicators for an integrated model of managing long COVID.

Long COVID: An approach to clinical assessment and management in primary care

Abstract:

Long COVID is an emerging public health threat, following swiftly behind the surges of acute infection over the course of the COVID-19 pandemic. It is estimated that there are already approximately 100 million people suffering from Long COVID globally, 0.5 million of whom are South African, and for whom our incomplete understanding of the condition has forestalled appropriate diagnosis and clinical care. There are several leading postulates for the complex, multi-mechanistic pathogenesis of Long COVID. Patients with Long COVID may present with a diversity of clinical phenotypes, often with significant overlap, which may exhibit temporal heterogeneity and evolution.

Post-acute care follow-up, targeted screening, diagnosis, a broad initial assessment and more directed subsequent assessments are necessary at the primary care level. Symptomatic treatment, self-management and rehabilitation are the mainstays of clinical care for Long COVID. However, evidence-based pharmacological interventions for the prevention and treatment of Long COVID are beginning to emerge. This article presents a rational approach for assessing and managing patients with Long COVID in the primary care setting.

The cost of primary care consultations associated with long COVID in non-hospitalised adults: a retrospective cohort study using UK primary care data

Abstract:

Objectives To assess incremental costs of primary care consultations associated with post-Covid-19 condition or long COVID, to estimate associated national costs for the United Kingdom population, and to assess risk factors associated with increased costs.

Design A retrospective cohort study using a propensity score matching approach with an incremental cost method to estimate primary care consultation costs associated with long COVID.

Setting UK based primary care general practitioner (GP), nurse and physiotherapist consultation data from the Clinical Practice Research Datalink Aurum primary care database from 31st January 2020 to 15th April 2021.

Participants 472,173 non-hospitalised adults with confirmed SARS-CoV-2 infection were 1:1 propensity score matched to a pool of eligible patients with the same index date, the same number of prior consultations, and similar background characteristics, but without a record of COVID-19. Patients diagnosed with Long COVID (3,871) and those with World Health Organisation (WHO) defined symptoms of long COVID (30,174) formed two subgroups within the cohort with confirmed SARS-CoV-2 infection.

Main outcome measures Costs were calculated using a bottom-up costing approach with consultation cost per working hour in pound sterling (£) obtained from the Personal Social Services Research Unit’s Unit Costs of Health and Social Care 2021. The average incremental cost in comparison to patients with no record of COVID-19 was produced for each patient group, considering only consultation costs at least 12 weeks from the SARS-CoV-2 infection date or matched date for the comparator group (from 15th April 2020 to 15th April 2021). A sensitivity analysis was undertaken which restricted the study population to only those who had at least 24 weeks of follow-up. National costs were estimated by extrapolating incremental costs to the cumulative incidence of COVID-19 in the UK Office for National Statistics COVID-19 Infection Survey. The impacts of risk factors on the cost of consultations beyond 12 weeks from SARS-CoV-2 infection were assessed using an econometric ordinary least squares (OLS) regression model, where coefficients were interpreted as the percentage change in cost due to a unit increase in the specific factor.

Results The incremental cost of primary care consultations potentially associated with long COVID was £2.44 per patient with COVID-19 per year. This increased to £5.72 in the sensitivity analysis. Extrapolating this to the UK population produced a cost estimate of £23,382,452 (90% credible interval: £21,378,567 to £25,526,052) or £54,814,601 (90% credible interval: £50,116,967 to £59,839,762) in the sensitivity analysis. Among patients with COVID-19 infection, a long COVID diagnosis and longer-term reporting of symptoms were associated with a 43% and 44% increase in primary care consultation costs respectively, compared to patients without long COVID symptoms. Older age (49% relative increase in costs in those aged 80 years or older compared to those aged 18 to 29 years), female sex (4% relative increase in costs compared to males), obesity (4% relative increase in costs compared to those of normal weight), comorbidities and the number of prior consultations were all associated with an increase in the cost of primary care consultations. By contrast, those from black ethnic groups had a 6% reduced relative cost compared to those from white ethnic groups.

Conclusions The costs of primary care consultations associated with long COVID in non-hospitalised adults are substantial. Costs are significantly higher among those diagnosed with long COVID, those with long COVID symptoms, older adults, females, and those with obesity and comorbidities.

What is already known on this topic?

  • Long COVID is a global public health challenge, with millions of people affected worldwide.

  • People with a history of long COVID use health services, including primary care, at a higher rate than uninfected individuals even beyond the period of acute infection.

  • The cost of this increased healthcare use is unknown, impeding planning and forecasting of resource requirements needed to adequately support people with long COVID.

What this study adds?

  • Beyond 12 weeks from acute infection, non-hospitalised adults with a history of SARS-CoV-2 infection cost primary care services an additional £2.44 per patient per year greater on average than patients with no prior evidence of infection.

  • Due to the high incidence of COVID-19, this represents a substantial cost to primary care services, in the UK exceeding £20 million for consultations associated with long COVID.

  • These incremental costs are greater in those with a formal diagnosis of long COVID, those reporting related symptoms, older adults, females, and those with obesity.

What Primary Care Practitioners Need to Know about the New NICE Guideline for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome in Adults

Abstract:

The new NICE guideline for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), published in October 2021, makes significant changes in treatment recommendations. It acknowledges the complexity of this chronic medical condition, which always impacts quality of life and can be profoundly disabling, recognising the prejudice and stigma that people with ME/CFS often experience in the absence of any specific diagnostic test.

The guideline outlines steps for accurate diagnosis, recognising post-exertional malaise as a core symptom; importantly, ME/CFS can now be diagnosed after just 3 months in a bid to improve long-term health outcomes. It recommends the need for individual, tailored management by a multi-disciplinary team, ensuring that the wellbeing of the individual is paramount. The guideline makes clear that any programme based on fixed incremental increases in physical activity or exercise, for example graded exercise therapy (GET), should not be offered as a treatment for ME/CFS and emphasises that cognitive behavioural therapy (CBT) should only be offered as a supportive intervention.

Because of the rigorous methodology required by NICE Committee review and the inclusion of the testimony of people with lived experience as committee members, this guideline will influence the future diagnosis and management of ME/CFS in the UK and beyond.

Prevalence of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) in Australian primary care patients: only part of the story?

Abstract:

Background: ME/CFS is a disorder characterized by recurrent fatigue and intolerance to exertion which manifests as profound post-exertional malaise. Prevalence studies internationally have reported highly variable results due to the 20 + diagnostic criteria. For Australia, the prevalence of ME/CFS based on current case definitions is unknown.

Objectives: To report prevalence of ME/CFS in patients aged ≥ 13 years attending Australian primary care settings for years 2015-2019, and provide context for patterns of primary care attendance by people living with ME/CFS.

Methodology: Conducted in partnership with the Patient Advisory Group, this study adopted a mixed methods approach. De-identified primary care data from the national MedicineInsight program were analyzed. The cohort were regularly attending patients, i.e. 3 visits in the preceding 2 years. Crude prevalence rates were calculated for years 2015-2019, by sex, 10-year age groups, remoteness and socioeconomic status. Rates are presented per 100,000population (95% confidence intervals (CI)). Qualitative data was collected through focus groups and in-depth 1:1 interview.

Results: Qualitative evidence identified barriers to reaching diagnosis, and limited interactions with primary care due to a lack of available treatments/interventions, stigma and disbelief in ME/CFS as a condition. In each year of interest, crude prevalence in the primary care setting ranged between 94.9/100,000 (95% CI: 91.5-98.5) and 103.9/100,000 population (95%CI: 100.3-107.7), equating to between 20,140 and 22,050 people living with ME/CFS in Australia in 2020. Higher rates were observed for age groups 50-59 years and 40-49 years. Rates were substantially higher in females (130.0-141.4/100,000) compared to males (50.9-57.5/100,000). In the context of the qualitative evidence, our prevalence rates likely represent an underestimate of the true prevalence of ME/CFS in the Australian primary care setting.

Conclusion: ME/CFS affects a substantial number of Australians. Whilst this study provides prevalence estimates for the Australian primary care setting, the qualitative evidence highlights the limitations of these. Future research should focus on using robust case ascertainment criteria in a community setting. Quantification of the burden of disease can be used to inform health policy and planning, for this understudied condition.

From neurasthenia to post-exertion disease: Evolution of the diagnostic criteria of chronic fatigue syndrome/myalgic encephalomyelitis

Abstract:

Changes in the terminology and diagnostic criteria for chronic fatigue syndrome/myalgic encephalomyelitis are explained in this paper. This syndrome is a complex and controversial entity of unknown origins. It appears in the medical literature in 1988, although clinical pictures of chronic idiopathic fatigue have been identified since the nineteenth century with different names, from neurasthenia, epidemic neuromyasthenia, and benign myalgic encephalomyelitis up to the current proposal of disease of intolerance to effort (post-effort). All of them allude to a chronic state of generalised fatigue of unknown origin, with limitations to physical and mental effort, accompanied by a set of symptoms that compromise diverse organic systems.

The International Classification of Diseases (ICD-10) places this syndrome in the section on neurological disorders (G93.3), although histopathological findings have not yet been found to clarify it. Multiple organic alterations have been documented, but a common biology that clarifies the mechanisms underlying this disease has not been established. It is defined as a neuro-immune-endocrine dysfunction, with an exclusively clinical diagnosis and by exclusion.

Several authors have proposed to include CFS/ME within central sensitivity syndromes, alluding to central sensitisation as the common pathophysiological substrate for this, and other syndromes. The role of the family doctor is a key figure in the disease, from the detection of those patients who present a fatigue of unknown nature that is continuous or intermittent for more than 6 months, in order to make an early diagnosis and establish a plan of action against a chronic disease with high levels of morbidity in the physical and mental sphere.

OBJECTIVE: To carry out a bibliographic review of the terminology and diagnostic criteria of the chronic fatigue syndrome/myalgic encephalomyelitis, in order to clarify the pathology conceptually, as a usefulness in the diagnosis of Primary Care physicians.

Experiences of general practitioner continuity among women with chronic fatigue syndrome/myalgic encephalomyelitis: a cross-sectional study

Abstract:

BACKGROUND: Continuity of care is important for patients with chronic illness in need of coordinated healthcare services from multiple providers. Little is known about how patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) experience continuity of GP care. This study explores how women with CFS/ME experience GP care across the three dimensions of continuity: informational, management, and relational continuity.

METHODS: This cross-sectional study uses questionnaire data collected from members of The Norwegian ME Association. Descriptive statistics and logistic regressions were used to estimate experiences of continuity, and associations with age, education, self-rated degree of CFS/ME, duration of the GP relation (GP duration), and number of GP visits for CFS/ME-related issues during the previous year (GP frequency).

RESULTS: Almost two-thirds of participants reported positive experiences across all three dimensions of GP continuity of care; 64.4% for informational, 64.1% for management, and 77.2% for relational continuity. Lower educational attainment was associated with more negative experiences of informational continuity (primary school only compared to university educated: odds ratio [OR] 0.12, confidence interval [CI] 0.03-0.49, p = 0.003). Compared to participants aged 40-59 years, those aged 60+ years were significantly less likely to have experienced poor (negative) management continuity (OR 0.25, CI 0.09-0.76, p = 0.014). A GP relationship of three or more years was associated with positive experiences of relational continuity (OR 2.32, CI 1.09-4.95, p = 0.030). Compared to those with moderate CFS/ME, those who graded their CFS/ME as severe or very severe were significantly more likely to have negative experiences of relational continuity (OR 0.38, CI 0.14-0.99, p = 0.047).

CONCLUSIONS: A large proportion of participants experienced all three aspects of continuity of GP care (especially the relational dimension) positively. Informational and management continuity scores were moderately lower. Our results suggest greater emphasis on information giving, feedback, and better coordination of care to be good strategies for practice improvement for this patient group.
