Measles, mumps, rubella prevention: how can we do better?

INTRODUCTION: Measles, mumps, and rubella incidence decreased drastically following vaccination programs' implementation. However, measles and mumps' resurgence was recently reported, outbreaks still occur, and challenges remain to control these diseases. AREAS COVERED: This qualitative narrative review provides an objective appraisal of the literature regarding current challenges in controlling measles, mumps, rubella infections, and interventions to address them. EXPERT OPINION: While vaccines against measles, mumps, and rubella (including trivalent vaccines) are widely used and effective, challenges to control these diseases are mainly related to insufficient immunization coverage and changing vaccination needs owing to new global environment (e.g. traveling, migration, population density). By understanding disease transmission peculiarities by setting, initiatives are needed to optimize vaccination policies and increase vaccination coverage, which was further negatively impacted by COVID-19 pandemic. Also, awareness of the potential severity of infections and the role of vaccines should increase. Reminder systems, vaccination of disadvantaged, high-risk and difficult-to-reach populations, accessibility of vaccination, healthcare infrastructure, and vaccination services management should improve. Outbreak preparedness should be strengthened, including implementation of high-quality surveillance systems to monitor epidemiology. While the main focus should be on these public health initiatives to increase vaccination coverage, slightly more benefits could come from evolution of current vaccines.

PLAIN LANGUAGE SUMMARYWhat is the context?Measles, mumps, and rubella are highly contagious diseases associated with significant medical and societal burden. Effective vaccines against these diseases are available, and the implementation of vaccination programs drastically reduced disease incidence globally. However, reports of measles and mumps outbreaks in the last few years highlight remaining challenges to eliminate these diseases.What does the review highlight?We conducted a literature review to identify challenges associated with controlling measles, mumps, and rubella infections, and interventions needed to address them. We identified 11 challenges mainly related to low immunization coverage and vaccine characteristics. Societal challenges could be addressed by increasing awareness of disease severity and vaccines impact, targeting high-risk, unvaccinated, and under-vaccinated populations, improving vaccination access, setting up clear outbreak preparedness plans, and implementing country-specific vaccination policies. System weaknesses could be addressed through improving vaccination services and health infrastructure, implementing high-quality surveillance, patient invite, and reminder systems, ensuring vaccine implementation and long-term supply. Interventions related to vaccine characteristic challenges could include adaptation of vaccination schedules (shorter interval between doses, administration of a third dose) and development of vaccines against emerging strains.What is the take-home message?Policymakers should support the following strategies to increase vaccination coverage and reach elimination of measles, mumps, and rubella: strengthening health systems and vaccination access; raising awareness of disease severity and vaccination impact; limiting disease propagation owing to global changing environment and population dynamics (traveling, migration); improving surveillance systems to rapidly address the immunity gaps against disease resurgence.

Delivering routine immunisations in London during the COVID-19 pandemic: lessons for future vaccine delivery. A mixed-methods study.

BACKGROUND: General practices in England have continued to care for patients throughout the COVID-19 pandemic by instigating major changes to service delivery. Immunisations have continued, although the number of vaccines delivered initially dropped in April 2020. AIM: To evaluate how COVID-19 impacted the delivery of immunisations in London and identify innovative practices to inform future delivery, including for COVID-19 vaccines. DESIGN & SETTING: A mixed-methods study of immunisation delivery in London, UK. METHOD: An online survey of London general practices was undertaken in May 2020 to produce a descriptive analysis of childhood immunisation delivery and identify innovative delivery models. Semi-structured interviews were conducted between August and November 2020 to explore innovative immunisation models, which were analysed thematically. RESULTS: Sixty-eight per cent (n = 830) of London practices completed the survey and 97% reported having continued childhood immunisation delivery. Common delivery adaptations included spaced-out appointments, calling parents beforehand, and having only one parent attend. Forty-three practices were identified as having innovative models, such as delivering immunisations outside practice buildings or offering drive-through services. The thematic analysis of 14 semi-structured interviews found that, alongside adaptations to immunisation delivery within practices, existing local networks collaborated to establish new immunisation delivery models. Local population characteristics affected delivery and provide insights for large-scale vaccine deployment. CONCLUSION: Immunisations continued during 2020 with practices adapting existing services. New delivery models were developed by building on existing local knowledge, experiences, and networks. Immunisation delivery during the pandemic, including for COVID-19 vaccines, should be tailored to local population needs by building on primary care immunisation expertise.

Influences on childhood immunisation decision-making in London's Gypsy and Traveller communities.

AIMS: Uptake of childhood immunisations is lower among Gypsy, Roma and Traveller (GRT) communities than in the general UK population. This small-scale study aimed to elicit insights from GRT mothers on their interaction with health services in London around childhood immunisations. The purpose was to inform a larger piece of work by the NHS England and Improvement (London) Public Health Commissioning Team to inform their planning to improve access to vaccination services for GRT communities in London. STUDY DESIGN: An exploratory qualitative study using semi-structured interviews and a focus group. METHODS: There was purposive sampling of mothers from any GRT background from south-west London using snowballing methods. One focus group and three interviews were conducted. A thematic analysis approach was used. RESULTS: A total of nine women were recruited and seven participated between March and April 2018. Five themes were identified: adherence with antenatal care, self-declared parenting expertise, family support, childhood immunisations, keep children healthy but 'they say wait on the MMR until they are talking'. CONCLUSION: Compliance with antenatal care, strong parenting beliefs and cohesive family support are strong influences on decision-making regarding immunisations. The women interviewed emphasised their own expertise in child rearing. This was occasionally at odds with the health advice provided by health professionals. The women widely shared their experiences of health professionals with other family and community members and this impacted on others' intention to vaccinate. These are key issues that should be considered when trying to improve uptake of immunisations in GRT families in a face-to-face manner. Equally, it warrants further exploration in a larger-scale study to see whether this reflects the wider community and in order to tailor supplementary immunisation activities to improve uptake.

Factors Affecting Delivery of the HPV Vaccination: A Focus Group Study With NHS School-Aged Vaccination Teams in London.

This study sought to identify barriers and facilitators to delivery of human papillomavirus (HPV) vaccination in schools. Four focus groups were conducted with 28 staff members, from four National Health Service school-aged vaccination (SAV) teams in London. Data were analyzed using thematic analysis. School engagement and support, and understanding and education about the vaccination (or conversely, a lack of) were identified as both barriers and facilitators. Limited school and team resources, fear of the vaccination, and poor consent form return were identified as barriers. Explanations for why some girls do not complete the vaccination series were provided. Individualizing approaches used to promote and encourage the vaccination was identified as a facilitating factor. Optimal delivery of the HPV vaccination program is dependent on school engagement and the allocation of time for SAV teams to promote vaccination uptake. Immunization program providers should work with schools to improve understanding and support of the HPV vaccination program.

Is partnership the answer? Delivering the national immunisation programme in the new English health system: a mixed methods study.

BACKGROUND: The English national health system experienced a major reorganisation in April 2013. This mixed methods study examined how staff managed to deliver the national immunisation programme within a new health infrastructure and explored the role and contribution of 'partnership working' to programme implementation. METHODS: A cross-sectional online questionnaire survey and a qualitative evaluation of an urban immunisation board were conducted in 2016. The questionnaire included 38 questions about immunisation responsibilities, collaboration, service evaluation and programme support. It was completed by 199 immunisation providers and 70 people involved in the management of the immunisation programme. The evaluation involved 12 semi-structured interviews, 3 observations of forum meetings and the review of forum meeting minutes. Descriptive statistical analysis of the survey data was performed using SPSS version 23 and qualitative data from both study components were uploaded to NVivo 11 and analysed thematically. RESULTS: Screening and Immunisation Teams were cited as responsible for programme leadership by 56% of survey respondents, but concerns were raised about their capacity to oversee larger geographies and a case made for decentralised accountability mechanisms. Only 44% of immunisation managers stated that poor performance was addressed adequately, and half of respondents thought that support given to providers was inadequate. Managers reported that partnership working improved the organisation (83%) and performance (78%) of immunisation, but stated it was more beneficial for information-sharing than implementation. A preference for a "locality working approach" with committees covering smaller health economies rather than larger commissioning areas was voiced. The immunisation board examined in the qualitative evaluation sought to achieve this by forging links with locally based steering committees, but also had to address internal challenges related to the role of the board and contribution of members to programmatic decision-making. CONCLUSIONS: Key challenges in delivering the immunisation programme were rooted in the new health infrastructure, which had created greater distance between commissioners and providers and resulted in the fragmentation of programme responsibilities. Partnership working bridged gaps but more needs to be done to strengthen accountability mechanisms and ensure that collaborative activities are outcome oriented and sustainable in the shifting environment of reorganisation.

Using social media as a strategy to address 'sophomore slump' in second year nursing students: A qualitative study.

INTRODUCTION: An important contributing factor to the shortfall in the nursing workforce is the high attrition rate of students from nursing programmes. Recently, researchers have begun to examine the 'sophomore slump' phenomenon, related to students' sense of low self-efficacy associated with learning in their second year of study, that may be related to attrition. BACKGROUND: Academic success is heavily influenced by self-efficacy, or a student's belief in their ability to be successful. Strategies that enhance self-efficacy include peer learning, which increases students' engagement and reinforces self-regulated learning. Social networking sites such as Facebook provide students the opportunity to take part in peer learning and may promote students' self-efficacy. AIM: The aim of the study was to develop a Facebook forum that utilised peer learning, to build self-efficacy related to learning, of students commencing into the second year of a three year nursing programme. METHODS: Students commencing into year two of a Bachelor of Nursing programme were invited to join a Facebook forum to support their study. One hundred and ninety-eight students accepted the invitation. Data was collected over a twelve-week period. Text from the Facebook forum was downloaded and analysed thematically. FINDINGS: Analysis suggests that Facebook forums may be a useful peer learning strategy to build students' self-efficacy related to study in the second year of nursing study. Students shared mastery experiences, provided modelling experiences, and used verbal persuasion to reframe problems which suggested that it helped build students' self-efficacy, and alleviated some of the physiological response associated with stress. CONCLUSION: The findings suggest that social media platforms are important tools by which students can engage in peer learning to build self-efficacy around their nursing studies. This may in part help address the 'sophomore slump' phenomenon, enhance students' learning experiences more widely, and impact on students' decisions to remain in nursing programmes.

Educational and skills-based interventions for preventing relationship and dating violence in adolescents and young adults.

BACKGROUND: Educational and skills-based interventions are often used to prevent relationship and dating violence among young people. OBJECTIVES: To assess the efficacy of educational and skills-based interventions designed to prevent relationship and dating violence in adolescents and young adults. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, PsycINFO, six other databases and a trials register on 7 May 2012. We handsearched the references lists of key articles and two journals (Journal of Interpersonal Violence and Child Abuse and Neglect). We also contacted researchers in the field. SELECTION CRITERIA: Randomised, cluster-randomised and quasi-randomised studies comparing an educational or skills-based intervention to prevent relationship or dating violence among adolescents and young adults with a control. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed study eligibility and risk of bias. For each study included in the meta-analysis, data were extracted independently by GF and one other review author (either CH, JN, SH or DS). We conducted meta-analyses for the following outcomes: episodes of relationship violence, behaviours, attitudes, knowledge and skills. MAIN RESULTS: We included 38 studies (15,903 participants) in this review, 18 of which were cluster-randomised trials (11,995 participants) and two were quasi-randomised trials (399 participants). We included 33 studies in the meta-analyses. We included eight studies (3405 participants) in the meta-analysis assessing episodes of relationship violence. There was substantial heterogeneity (I(2) = 57%) for this outcome. The risk ratio was 0.77 (95% confidence interval (CI) 0.53 to 1.13). We included 22 studies (5256 participants) in the meta-analysis assessing attitudes towards relationship violence. The standardised mean difference (SMD) was 0.06 (95% CI -0.01 to 0.15). We included four studies (887 participants) in the meta-analysis assessing behaviour related to relationship violence; the SMD was -0.07 (95% CI -0.31 to 0.16). We included 10 studies (6206 participants) in the meta-analysis assessing knowledge related to relationship violence; the results showed an increase in knowledge in favour of the intervention (SMD 0.44, 95% CI 0.28 to 0.60) but there was substantial heterogeneity (I(2) = 52%). We included seven studies (1369 participants) in the meta-analysis assessing skills related to relationship violence. The SMD was 0.03 (95% CI -0.11 to 0.17). None of the included studies assessed physical health, psychosocial health or adverse outcomes. Subgroup analyses showed no statistically significant differences by intervention setting or type of participants. The quality of evidence for all outcomes included in our meta-analysis was moderate due to an unclear risk of selection and detection bias and a high risk of performance bias in most studies. AUTHORS' CONCLUSIONS: Studies included in this review showed no evidence of effectiveness of interventions on episodes of relationship violence or on attitudes, behaviours and skills related to relationship violence. We found a small increase in knowledge but there was evidence of substantial heterogeneity among studies. Further studies with longer-term follow-up are required, and study authors should use standardised and validated measurement instruments to maximise comparability of results.

Effective smoking cessation interventions for COPD patients: a review of the evidence.

OBJECTIVES: To review the effectiveness of smoking cessation interventions offered to chronic obstructive pulmonary disease (COPD) patients, and identify barriers to quitting experienced by them, so that a more effective service can be developed for this group. DESIGN: A rapid systematic literature review comprising computerized searches of electronic databases, hand searches and snowballing were used to identify both published and grey literature. SETTING: A review of studies undertaken in north-western Europe (defined as: United Kingdom, Ireland, France, Germany, Benelux and Nordic countries). PARTICIPANTS: COPD patients participating in studies looking at the effectiveness of smoking cessation interventions in this patient group, or exploring the barriers to quitting experienced by these patients. METHOD: Quantitative and qualitative papers were selected according to pre-specified inclusion and exclusion criteria, critically appraised, and quantitative papers scored against the NICE Levels of Evidence standardized hierarchy. MAIN OUTCOME MEASURE: Percentages of successful quitters and length of quit, assessed by self-report or biochemical analysis. Among qualitative studies, identified barriers to smoking cessation had to be explored. RESULTS: Three qualitative and 13 quantitative papers were finally selected. Effective interventions and barriers to smoking cessation were identified. Pharmacological support with Buproprion combined with counselling was significantly more efficacious in achieving prolonged abstinence than a placebo by 18.9% (95% CI 3.6-26.4%). Annual spirometry with a brief smoking cessation intervention, followed by a personal letter from a doctor, had a significantly higher ≥1 year abstinence rate at three years among COPD patient smokers, compared to smokers with normal lung function (P < 0.001; z = 3.93). Identified barriers to cessation included: patient misinformation, levels of motivation, health beliefs, and poor communication with health professionals. CONCLUSION: Despite the public health significance of COPD, there is a lack of high-quality evidence showing which smoking cessation support methods work for these patients. This review describes three effective interventions, as well as predictors of quitting success that service providers could use to improve quit rates in this group. Areas that would benefit from urgent further research are also identified.

Opportunistic screening for Chlamydia: a pilot study into male perspectives on provision of Chlamydia screening in a UK university.

BACKGROUND: Since 2003, the University of Leeds has been a pilot site for the National Chlamydia Screening Programme (NCSP), which offers opportunistic screening to asymptomatic people under the age of 25. Uptake among men is low. The purpose of this study is to explore perceptions and acceptability of the provision of Chlamydia screening in the University of Leeds among 18-25-year-old male students. METHODS: Using a purposive sample of 15 male students aged between 19 and 24, two focus group sessions were conducted within university grounds. RESULTS: Thematic analysis of the data revealed that male attitudes about Chlamydia screening were affected by: (1) lack of knowledge about Chlamydia and screening; (2) social embarrassment about Chlamydia; (3) reluctance to seek medical help; (4) perception that Chlamydia was a 'woman's disease' and (5) indifference about health promotion campaigns. CONCLUSION: To encourage the uptake of opportunistic screening of Chlamydia, men under 25 years should be made aware of their responsibility for their own sexual health. Emphasis can also be placed on the non-invasiveness, ease and privacy of the test.

After 'Unit 1421': an exploratory study into female students' attitudes and behaviours towards binge drinking at Leeds University.

BACKGROUND: Binge drinking has been highlighted as a growing problem in the UK, particularly amongst females aged 18-25 years. University of Leeds is situated within a population that has one of the highest reported statistics of binge drinking in the UK. In September 2006, the 'Unit 1421' campaign was launched at University of Leeds with the aim to promoted sensible drinking amongst students. The aim of this study is to explore female perspectives on binge drinking and on 'Unit 1421' campaign in the University of Leeds. METHODS: Using a purposive sample, two focus groups were conducted with 12 female students aged 18-23 years within university grounds. Participants were recruited via email and poster advertisements on campus. RESULTS: Four main themes emerged from the data: (i) lay perception of binge drinking; (ii) pressures of matching the drinking patterns of male peers; (iii) student rite of passage; (iv) evaluation of the 'Unit 1421' campaign. CONCLUSION: The social context of student life impacts greatly upon students' choices to binge drink. The norms, beliefs and morals governing student culture and the use of alcohol to assert identity should be considered when tailoring health promotion efforts to this target audience. Larger qualitative and ultimately quantitative studies are warranted to extrapolate and test the social pressures on drinking in this age group.

The Parkinson's Disease Questionnaire (PDQ-39): evidence for a method of imputing missing data.

BACKGROUND: The Parkinson's Disease Questionnaire (PDQ-39) is the most widely used Parkinson's specific measure of health status. It is increasingly used in treatment trials, sometimes as a primary end-point, where any missing data can potentially cause difficulties in analyses. OBJECTIVES: The purpose of this article is to evaluate the Expectation Maximisation (EM) algorithm for the imputation of missing dimension scores on the 39-item PDQ-39. METHODS: A postal survey of patients diagnosed with Parkinson's disease (PD). A total of 1,372 patients were surveyed and 839 (61.15%) questionnaires returned completed or partially completed. Of these, complete PDQ data were available in 715 (85.22%) cases. Data were deleted from this complete dataset and a sub-set of 200 respondents from this dataset and then imputed using the EM algorithm; results were then compared to the dataset before data deletion. RESULTS: Results gained from imputation of data closely mirrored that of the complete dataset in each case. Descriptive statistics, mean scores and spread of scores were almost identical between original and imputed datasets. Furthermore, original and imputed datasets were highly correlated [intra-class correlation coefficient (ICC) = 0.93 or greater], and mean differences were small (+/-1.00). CONCLUSIONS: The results suggest that the use of EM for the PDQ-39 provides data that closely mirrors the original when this has been deliberately removed. Consequently, EM is likely to be appropriate for trials using the PDQ that contains missing data points.

Management of respiration in MND/ALS patients: an evidence based review.

This systematic review comprises an objective appraisal of the evidence in regard to the management of respiration in patients with motor neuron disease (MND/ALS). Studies were identified through computerised searches of 32 databases. Internet searches of websites of drug companies and MND/ALS research web sites, 'snow balling' and hand searches were also employed to locate any unpublished study or other 'grey literature' on respiration and MND/ALS. Since management of MND/ALS involves a number of health professionals and care workers, searches were made across multiple disciplines. No time frame was imposed on the search in order to increase the probability of identifying all relevant studies, although there was a final limit of March 2005. Recommendations for patient and carer-based guidelines for the clinical management of respiration for MND/ALS patients are suggested on the basis of qualitative analyses of the available evidence. However, these recommendations are based on current evidence of best practice, which largely comprises observational research and clinical opinion. There is a clear need for further evidence, in particular randomised and non-randomised controlled trials on the effects of non-invasive ventilation and additional larger scale cohort studies on the issues of initial assessment of respiratory symptoms, and management and timing of interventions.

Measuring outcomes for neurological disorders: a review of disease-specific health status instruments for three degenerative neurological conditions.

Health-related quality-of-life measures have been increasingly used in research into neurological disorders in recent years. The aim of this paper is to provide an objective appraisal of the evidence in regard to disease-specific quality-of-life measures used in research on health interventions for three degenerative neurological disorders: multiple sclerosis, motor neurone disease/amyotrophic lateral sclerosis and Parkinson's disease. A comprehensive search strategy was developed to include nine relevant electronic databases. Only studies pertaining to patient-based outcome measurements in multiple sclerosis, motor neurone disease and Parkinson's disease were included. We identified 76 eligible studies. As studies consisted of descriptive and cross-sectional survey study designs, results were reported qualitatively rather than in the form of a meta-analysis. Four disease-specific measures were found for Parkinson's disease, 11 for multiple sclerosis and one for motor neurone disease. We conclude that health-related quality-of-life measures are useful in assessing the impact of treatments and interventions for neurological disorders. However, further research is needed on the development of instruments using psychometric methods and on the validation, utilization and responsiveness of instruments to change.
