Quality of Care for Patients With Multiple Sclerosis-A Review of Existing Quality Indicators

Background: The care of patients with multiple sclerosis (MS) calls for a lifelong guidance and treatment and results in a high resource utilization. Therefore, strategies for the assessment and improvement of the care process are crucial. Quality indicators have become a widely used instrument to determine quality in many areas of the healthcare system. The currently available sets of indicators for the quality of MS care are summarized in this review.

Methods: A literature search was conducted for reports that include statements on quality indicators for the care of people with MS. For the determination of the strength of the underlying evidence of the identified publications appropriate criteria of the PRISMA and AGREE-Statements were used. A further prioritization of the eligible indicators was based on the internal grading by the initial authors.

Results: Of the 465 included records in the search, 6 sources were finally identified, 3 demonstrating a high and the others a medium strength of evidence. In total, these six reports described 226 quality indicators for the treatment of MS. Of them, 147 were further included in the assessment due to the scope of this article. Among the 101 indicators that originated from reports with a high strength of evidence, 6 also had a high initial internal grading. These six identified quality indicators describe five important characteristics of a high-quality care of MS.

Conclusion: The search led to a scientifically evident set of six quality indicators for the assessment of care for patients with MS. These should be seen as starting points in the development of comprehensive sets of quality indicators in MS that addresses the individual objective of their use.

Multiple Sclerosis, Disease-Modifying Therapies and COVID-19: A Systematic Review on Immune Response and Vaccination Recommendations

Understanding the risks of COVID-19 in patients with Multiple Sclerosis (MS) receiving disease-modifying therapies (DMTs) and their immune reactions is vital to analyze vaccine response dynamics. A systematic review on COVID-19 course and outcomes in patients receiving different DMTs was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Emerging data on SARS-CoV-2 vaccines was used to elaborate recommendations. Data from 4417 patients suggest that MS per se do not portend a higher risk of severe COVID-19. As for the general population, advanced age, comorbidities, and higher disability significantly impact COVID-19 outcomes. Most DMTs have a negligible influence on COVID-19 incidence and outcome, while for those causing severe lymphopenia and hypogammaglobulinemia, such as anti-CD20 therapies, there might be a tendency of increased hospitalization, worse outcomes and a higher risk of re-infection. Blunted immune responses have been reported for many DMTs, with vaccination implications. Clinical evidence does not support an increased risk of MS relapse or vaccination failure, but vaccination timing needs to be individually tailored. For cladribine and alemtuzumab, it is recommended to wait 3-6 months after the last cycle until vaccination. For the general anti-CD20 therapies, vaccination must be deferred toward the end of the cycle and the next dose administered at least 4-6 weeks after completing vaccination. Serological status after vaccination is highly encouraged. Growing clinical evidence and continuous surveillance are extremely important to continue guiding future treatment strategies and vaccination protocols.

Information provision for people with multiple sclerosis

BACKGROUND

People with multiple sclerosis (MS) are confronted with a number of important uncertainties concerning many aspects of the disease. These include diagnosis, prognosis, disease course, disease-modifying therapies, symptomatic therapies, and non-pharmacological interventions, among others. While people with MS demand adequate information to be able to actively participate in medical decision making and to self manage their disease, it has been shown that patients' disease-related knowledge is poor, therefore guidelines recommend clear and concise high-quality information at all stages of the disease. Several studies have outlined communication and information deficits in the care of people with MS. However, only a few information and decision support programmes have been published.

OBJECTIVES

The primary objectives of this updated review was to evaluate the effectiveness of information provision interventions for people with MS that aim to promote informed choice and improve patient-relevant outcomes, Further objectives were to evaluate the components and the developmental processes of the complex interventions used, to highlight the quantity and the certainty of the research evidence available, and to set an agenda for future research.

SEARCH METHODS

For this update, we searched the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group Specialised Register, which contains trials from CENTRAL (the Cochrane Library 2017, Issue 11), MEDLINE, Embase, CINAHL, LILACS, PEDro, and clinical trials registries (29 November 2017) as well as other sources. We also searched reference lists of identified articles and contacted trialists.

SELECTION CRITERIA

Randomised controlled trials (RCTs), cluster-randomised controlled trials, and quasi-randomised trials comparing information provision for people with MS or suspected MS (intervention groups) with usual care or other types of information provision (control groups) were eligible.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the retrieved articles for relevance and methodological quality and extracted data. Critical appraisal of studies addressed the risk of selection bias, performance bias, attrition bias, and detection bias. We contacted authors of relevant studies for additional information.

MAIN RESULTS

We identified one new RCT (73 participants), which when added to the 10 previously included RCTs resulted in a total of 11 RCTs that met the inclusion criteria and were analysed (1387 participants overall; mean age, range: 31 to 51; percentage women, range: 63% to 100%; percentage relapsing-remitting MS course, range: 45% to 100%). The interventions addressed a variety of topics using different approaches for information provision in different settings. Topics included disease-modifying therapy, relapse management, self care strategies, fatigue management, family planning, and general health promotion. The active intervention components included decision aids, decision coaching, educational programmes, self care programmes, and personal interviews with physicians. All studies used one or more components, but the number and extent differed markedly between studies. The studies had a variable risk of bias. We did not perform meta-analyses due to marked clinical heterogeneity. All five studies assessing MS-related knowledge (505 participants; moderate-certainty evidence) detected significant differences between groups as a result of the interventions, indicating that information provision may successfully increase participants' knowledge. There were mixed results on decision making (five studies, 793 participants; low-certainty evidence) and quality of life (six studies, 671 participants; low-certainty evidence). No adverse events were detected in the seven studies reporting this outcome.

AUTHORS' CONCLUSIONS

Information provision for people with MS seems to increase disease-related knowledge, with less clear results on decision making and quality of life. The included studies in this review reported no negative side effects of providing disease-related information to people with MS. Interpretation of study results remains challenging due to the marked heterogeneity of interventions and outcome measures.

Mechanisms of action of ACTH in the management of relapsing forms of multiple sclerosis

Acute and subacute inflammation, the mechanisms by which demyelination and axonal loss occur in multiple sclerosis (MS), result from the migration of activated immune cells into the central nervous system parenchyma. The triggering antigen is unknown, but the process involves deregulated immune response of T and B lymphocytes, macrophages, and mediators with expansion of autoreactive T cells creating a shift in the balance of pro- and anti-inflammatory cytokines favoring inflammation. Ongoing disease activity and exacerbations early in the course of relapsing-remitting MS may prevent full remission and propagate future progressive disability. A key strategy of immune therapy is timely initiation of treatment to achieve remission, followed by maintenance of remission. In this context, treatment with high-dose methylprednisolone (MP) is currently recommended to induce a faster recovery from a clinical exacerbation that results from an acute inflammatory attack. Adrenocorticotropic hormone (ACTH or corticotropin) gel is an alternative for patients who do not respond to or do not tolerate corticosteroids. ACTH is a universal agonist in the melanocortin (MC) system and, as such, among other functions, stimulates the adrenal cortex to produce cortisol. MCs are a family of peptides that includes ACTH and other MC peptides. This system has five classes of receptors, all of which show a strong affinity for ACTH, suggesting a more complex and dynamic mechanism than only inducing endogenous corticosteroid production. ACTH and MCs regulate processes relevant to MS, including anti-inflammatory and immunomodulatory functions involving lymphocytes, macrophages, the sympathetic nervous system involved in inflammatory processes, and reduction of pro-inflammatory cytokines. The clinical implications of the mechanistic differences between corticosteroid and ACTH gel treatment remain to be elucidated. Recent data show that patients experiencing an acute exacerbation, who previously had suboptimal response to or were unable to tolerate MP treatment, showed positive clinical outcomes with fewer adverse events with ACTH gel.
