Interpersonal ethnic-racial discrimination and tobacco products: The moderating role of critical action

OBJECTIVE

The present study aimed to understand the role of critical action, sociopolitical participation, an essential form of consciousness in the relationship between interpersonal discrimination and the use of tobacco products.

METHOD

The present study was part of a more extensive longitudinal study on students' genetic and environmental experiences. To examine these associations, 164 racially minoritized college students (Mage = 19.86, SD = 0.28) were surveyed for this study.

RESULTS

Findings indicated that the relation between interpersonal ethnic-racial discrimination (IERD) and tobacco products was moderated by critical action. Specifically, IERD was associated with greater use of tobacco products when students had low critical consciousness-critical action. The relation between IERD and the use of tobacco products became nonsignificant when students had high critical action.

CONCLUSIONS

Critical action was protective in mitigating increased tobacco use in the context of discrimination experiences. Research, clinical, and policy implications are discussed in efforts to reduce tobacco-related disparities among racially minoritized college students.

Protective factors for adverse childhood experiences: Scoping review and evidence gap map

OBJECTIVE

Adverse childhood experiences (ACES) negatively impact mental, physical, and behavioral health of adults. To develop empirically supported interventions to reduce the impact of ACES, we need to have a strong empirical base of research on modifiable protective factors that reduce the link between ACES and health outcomes. The current review is focused on assessing the state of the literature on modifiable protective factors on the ACE-health outcome relationship in adults.

METHOD

We conducted a scoping review in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. A systematic search for peer-reviewed literature published in English was conducted in Medline, Embase, PsycINFO, CINAHL, and Web of Science from inception of the databases to January 5, 2023. We then constructed an evidence gap map to provide an innovative, visual approach to guide research prioritization.

RESULTS

Seventy-seven articles met inclusion criteria. Findings indicated that the majority focused on mental health outcomes (59%), and investigated individual (52%) and general social support (23%) protective factors. Also, the majority of the work was done in North America (65%) with predominantly female samples.

CONCLUSIONS

Future studies should focus on addressing gaps in our understanding of what factors may buffer the influence of ACES on physical health outcomes and risky health behaviors and our understanding of family and nonfamily relationships and community and cultural protective factors on the ACE-health outcome relationship in adults. Additionally, research is needed that focuses on samples that are more gender diverse and from countries outside of North America. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Assessing the dimensionality and construct validity of the military stigma scale across current service members

US service members are at elevated risk for distress and suicidal behavior, compared to the general US population. However, despite the availability of evidence-based treatments, only 40% of Service members in need of mental health care seek help. One potential reason for the lower use of services is that service members experience stigma or concerns that the act of seeking mental health care from a mental health provider carries a mark of disgrace. The Military Stigma Scale (MSS) was designed to assess two theoretical dimensions of help-seeking stigma (public and self), specifically among service members. The goal of the current study was to further examine the validity of the MSS among 347 active duty service members. Examination of unidimensional, two-factor, and bifactor models revealed that a bifactor model, with a general (overall stigma), two specific factors (public and self-stigma), and one method factor (accounting for negatively worded items) provided the best fit to the data. Ancillary reliability analyses also supported the MSS measuring a broad stigma factor associated with seeking mental health care in the military. Subsequent model analyses showed that the MSS was associated with other stigma-related constructs. Overall, findings suggest that the MSS is a reliable and validated scale that can be used to assess military help-seeking stigma and to evaluate results of programs designed to reduce stigma.

e-Consent in UK academic-led clinical trials: current practice, challenges and the need for more evidence

BACKGROUND

During the COVID-19 pandemic, in-person healthcare visits were reduced. Consequently, trial teams needed to consider implementing remote methods for conducting clinical trials, including e-Consent. Although some clinical trials may have implemented e-Consent prior to the pandemic, anecdotes of uptake for this method increased within academic-led trials. When the increased use of this process emerged, representatives from several large academic clinical trial groups within the UK collaborated to discuss ways in which trialists can learn from one another when implementing e-Consent.

METHODS

A survey of UKCRC-registered Clinical Trials Units (CTUs) was undertaken in April-June 2021 to understand the implementation of and their views on the use of e-Consent and experiences from the perspectives of systems programmers and quality assurance staff on the use of e-Consent. CTUs not using e-Consent were asked to provide any reasons/barriers (including no suitable trials) and any plans for implementing it in the future. Two events for trialists and patient and public involvement (PPI) representatives were then held to disseminate findings, foster discussion, share experiences and aid in the identification of areas that the academic CTU community felt required more research.

RESULTS

Thirty-four (64%) of 53 CTUs responded to the survey, with good geographical representation across the UK. Twenty-one (62%) of the responding CTUs had implemented e-Consent in at least one of their trials, across different types of trials, including CTIMPs (Clinical Trial of Investigational Medicinal Product), ATIMPs (Advanced Therapy Medicinal Products) and non-CTIMPs. One hundred ninety-seven participants attended the two workshops for wide-ranging discussions.

CONCLUSION

e-Consent is increasingly used in academic-led trials, yet uncertainties remain amongst trialists, patients and members of the public. Uncertainties include a lack of formal, practical guidance and a lack of evidence to demonstrate optimal or appropriate methods to use. We strongly encourage trialists to continue to share their own experiences of the implementation of e-Consent.

Incidence and sociodemographic, living environment and maternal health associations with stillbirth in a tertiary healthcare setting in Kano, Northern Nigeria

Background

Almost two million stillbirths occur annually, most occurring in low- and middle-income countries. Nigeria is reported to have one of the highest stillbirth rates on the African continent. The aim was to identify sociodemographic, living environment, and health status factors associated with stillbirth and determine the associations between pregnancy and birth factors and stillbirth in the Murtala Mohammed Specialist Hospital, Kano, Nigeria.

Methods

A three-month single-site prospective observational feasibility study. Demographic and clinical data were collected. We fitted bivariable and multivariable models for stillbirth (yes/no) and three-category livebirth/macerated stillbirth/non-macerated stillbirth outcomes to explore their association with demographic and clinical factors.

Findings

1,998 neonates and 1,926 mothers were enrolled. Higher odds of stillbirth were associated with low-levels of maternal education, a further distance to travel to the hospital, living in a shack, maternal hypertension, previous stillbirth, birthing complications, increased duration of labour, antepartum haemorrhage, prolonged or obstructed labour, vaginal breech delivery, emergency caesarean-section, and signs of trauma to the neonate following birth.

Interpretation

This work has obtained data on some factors influencing stillbirth. This in turn will facilitate the development of improved public health interventions to reduce preventable deaths and to progress maternal health within this site.

Development of a core outcome set for the evaluation of interventions to enhance trial participation decisions on behalf of adults who lack capacity to consent: a mixed methods study (COnSiDER Study)

BACKGROUND

Trials involving adults who lack capacity to provide consent rely on proxy or surrogate decision-makers, usually a family member, to make decisions about participation. Interventions to enhance proxy decisions about trial participation are now being developed. However, a lack of standardised outcome measures limits evaluation of these interventions. The aim of this study was to establish an agreed standardised core outcome set (COS) for use when evaluating interventions to improve proxy decisions about trial participation.

METHODS

We used established methods to develop the COS including a consensus study with key stakeholder groups comprising those who will use the COS in research (researchers and healthcare professionals) and patients or their representatives. Following a scoping review to identify candidate items, we used a modified two-round Delphi survey to achieve consensus on core outcomes, with equivocal items taken to a consensus meeting for discussion. The COS was finalised following an online consensus meeting in October 2020.

RESULTS

A total of 28 UK stakeholders (5 researchers, 10 trialists, 3 patient/family representatives, 7 recruiters and 3 advisors/approvers) participated in the online Delphi survey to rank candidate items from the scoping review (n = 36) and additional items proposed by participants (n = 1). Items were broadly grouped into three categories: how family members make decisions, their experiences of making decisions, and the personal aspects that influence the decision. Following the Delphi survey, 27 items were included and ten items exhibited no consensus which required discussion at the consensus meeting. Sixteen participants attended the meeting, including additional patient/family representatives invited to increase representation from this key group (n = 2). We reached consensus for the inclusion of 28 outcome items, including one selected at the consensus meeting.

CONCLUSIONS

The study identified outcomes that should be measured as a minimum in all evaluations of interventions to enhance proxy decisions about trials. These relate to the process of decision-making, proxies' experience of decision-making, and factors that influence decision-making such as understanding. Further work with people with impairing conditions and their families is needed to explore their views about the COS and to identify appropriate outcome measures and timing of measurement.

A qualitative focus group study concerning perceptions and experiences of Nigerian mothers on stillbirths

Objective

To explore the experiences and perceptions of stillbirth among mothers from a tertiary medical centre in Kano, Northern Nigeria.

Design

Qualitative, interpretative.

Setting

Tertiary healthcare facility, Murtala Muhammad Specialist Hospital (MMSH), Kano, Northern Nigeria.

Sample

Mothers who had given birth to a liveborn baby at the MMSH in the prior 6 months (n = 31). In order to capture the experiences and perception of stillbirth within this cohort we approached mothers who had in a previous pregnancy experienced a stillbirth. Of the 31 who attended 16 had a previous stillbirth.

Methods

Semi-structured Focus Group Discussions, consisting of open-ended questions about stillbirth, beliefs, experiences and influences were held in MMSH, conducted over 1 day.

Results

Our findings highlight that this is a resource-poor tertiary facility serving an ever-growing population, increasing strain on the hospital and healthcare workers. Many of the participants highlighted needing permission from certain family members before accessing healthcare or medical treatment. We identified that mothers generally have knowledge on self-care during pregnancy, yet certain societal factors prevented that from being their priority. Judgement and blame was a common theme, yet a complex area entwined with traditions, superstitions and the pressure to procreate with many mothers described being made to feel useless and worthless if they did not birth a live baby.

Conclusions

As access to healthcare becomes easier, there are certain traditions, family and social dynamics and beliefs which conflict with scientific knowledge and act as a major barrier to uptake of healthcare services. The findings highlight the need for investment in maternity care, appropriate health education and public enlightenment; they will help inform appropriate interventions aimed at reducing stigma around stillbirth and aide in educating mothers about the importance of appropriate health seeking behaviour. Stillbirths are occurring in this area of the world unnecessarily, globally there has been extensive research conducted on stillbirth prevention. This research has highlighted some of the areas which can be tackled by modifying existing successful interventions to work towards reducing preventable stillbirths.

The Use of Posturography in Investigating the Risk of Falling in Frail or Prefrail Older People with Diabetes

BACKGROUND

In older people, diabetes is associated with an increased risk of falls and frailty. The value of using posturography for evaluating the risk of falling is unclear. In theory, a time-scale analysis should increase the metrological properties of the posturography assessment.

OBJECTIVES

This study aimed to determine which posturographic parameters can be used to identify fall-risk patients in a frail diabetic older population and to assess their interest in comparison to usual clinical trials for gait and balance.

DESIGN

This is a prospective observational cohort.

SETTINGS

frail or pre-frail diabetic patients, in Bordeaux, France.

PARTICIPANTS

84 patients were included in the study (mean age 80.09 years, 64.5% of men).Criteria for inclusion were: age over 70 years, diabetes mellitus for over 2 years, and at least one of the Fried's frailty criteria.

MEASUREMENTS

Gait and balance assessments were undertaken at baseline: Static posturography, the timed up and go test, short physical performance battery, and (gait) walking speed. Raw data from posturography were used for wavelet analysis. Data on self reported new falls were collected prospectively during 6 months.

RESULTS

The posturography parameter most useful was area of 90% confidence ellipse of statokinesigram (COP90area): area under the ROC curve AUC = 0.617 (95% CI, 0.445-0.789) and OR=1.003 (95%CI 1.000-1.005) p =0.05. The optimum clinical test was the time to walk over 4m AUC=0.735 (95%CI, 0.587-0.882) and OR=1.42 (95%CI 1.08-1.87) p= 0.013.

CONCLUSION

Posturography has limited utility for assessment of falls risk in frail older people with diabetes. Gait and balance clinical assessments such as walking speed continue to retain their value.

What the public think about participation in medical research during an influenza pandemic: an international cross-sectional survey

OBJECTIVES

The public and patients are primary contributors and beneficiaries of pandemic-relevant clinical research. However, their views on research participation during a pandemic have not been systematically studied. We aimed to understand public views regarding participation in clinical research during a hypothetical influenza pandemic.

STUDY DESIGN

This is an international cross-sectional survey.

METHODS

We surveyed the views of nationally representative samples of people in Belgium, Poland, Spain, Ireland, the United Kingdom, Canada, Australia and New Zealand, using a scenario-based instrument during the 2017 regional influenza season. Descriptive and regression analyses were conducted.

RESULTS

Of the 6804 respondents, 5572 (81.8%) thought pandemic-relevant research was important, and 5089 (74.8%) thought 'special rules' should be applied to make this research feasible. The respondents indicated willingness to take part in lower risk (4715, 69.3%) and higher risk (3585, 52.7%) primary care and lower risk (4780, 70.3%) and higher risk (4113, 60.4%) intensive care unit (ICU) study scenarios. For primary care studies, most (3972, 58.4%) participants preferred standard enrolment procedures such as prospective written informed consent, but 2327 (34.2%) thought simplified procedures would be acceptable. For ICU studies, 2800 (41.2%) preferred deferred consent, and 2623 (38.6%) preferred prospective third-party consent. Greater knowledge about pandemics, trust in a health professional, trust in the government, therapeutic misconception and having had ICU experience as a patient or carer predicted increased willingness to participate in pandemic-relevant research.

CONCLUSIONS

Our study indicates current public support for pandemic-relevant clinical research. Tailored information and initiatives to advance research literacy and maintain trust are required to support pandemic-relevant research participation and engagement.

Assessing patient-reported outcomes for automated insulin delivery systems: the psychometric properties of the INSPIRE measures

AIM

Participants in clinical trials assessing automated insulin delivery systems report perceived benefits and burdens that reflect their experiences and may predict their likelihood of uptake and continued use of this novel technology. Despite the importance of understanding their perspectives, there are no available validated and reliable measures assessing the psychosocial aspects of automated insulin delivery systems. The present study assesses the initial psychometric properties of the INSPIRE measures, which were developed for youth and adults with Type 1 diabetes, as well as parents and partners.

METHODS

Data from 292 youth, 159 adults, 150 parents of youth and 149 partners of individuals recruited from the Type 1 Diabetes Exchange Registry were analysed. Participants completed INSPIRE questionnaires and measures of quality of life, fear of hypoglycaemia, diabetes distress, glucose monitoring satisfaction. Exploratory factor analysis assessed factor structures. Associations between INSPIRE scores and other measures, HbA_1c , and technology use assessed concurrent and discriminant validity.

RESULTS

Youth, adult, parent and partner measures assess positive expectancies of automated insulin delivery systems. Measures range from 17 to 22 items and are reliable (α = 0.95-0.97). Youth, adult and parent measures are unidimensional; the partner measure has a two-factor structure (perceptions of impact on partners versus the person with diabetes). Measures showed concurrent and discriminant validity.

CONCLUSIONS

INSPIRE measures assessing the positive expectancies of automated insulin delivery systems for youth, adults, parents and partners have meaningful factor structures and are internally consistent. The developmentally sensitive INSPIRE measures offer added value as clinical trials test newer systems, systems become commercially available and clinicians initiate using these systems.

The acceptability of fluoride varnish and fissure sealant treatments in children aged 6-9 delivered in a school setting

OBJECTIVE

To assess the acceptability of fluoride varnish and fissure sealant treatments for children. To investigate the acceptability of delivering this treatment in a school setting for children, parents, clinicians and school staff.

BASIC RESEARCH DESIGN

Semi-structured interviews (with children, parents, clinicians and school staff) and a questionnaire (for school staff) as part of a two-arm, randomised clinical trial.

PARTICIPANTS

Children aged 6-9, their parents, clinical staff and school staff.

INTERVENTIONS

Fluoride varnish or fissure sealant was delivered to children from the ages of 6 to 9 years for 36 months, by a community dental service in a school setting. Fluoride varnish was re-applied every 6 months; fissure sealant was applied once to first permanent molars and re-applied as required.

RESULTS

Interviews with children a few days after treatment indicated little difference in preference; acceptability at this point was driven by factors such as finding it fun to visit 'the van' (i.e. mobile dental unit) and receiving a "sticker" rather than specific treatment received. Interviews with parents, clinicians and school staff indicated high acceptability of delivering this type of intervention in a school setting; this may have been partly due to the service being delivered by a well-established, child-oriented community dental service which delivered the clinical trial.

CONCLUSIONS

Preventive fluoride varnish and fissure sealant treatments in a school setting has high overall acceptability.

Frailty and Brain-Muscle Correlates in Older People With Type 2 Diabetes: A structural-MRI Explorative Study

OBJECTIVES

Muscle alterations, mainly functional alterations are frequently observed in older people with type 2 diabetes (T2DM). Sarcopenia may be one mechanism of transition to frailty in these people. Thus, we aim to explore the characteristics of muscle and its association with cerebral grey matter volumes within this group.

METHODS

Single center study nested within the international MID-Frail (a randomized clinical trial to evaluate the effectiveness of a multi-modal intervention in older people with T2DM on frailty and quality of life) trial participants underwent both brain and muscle T1 MRI, nutritional and functional assessments. Muscle areas were measured in rectus femoris (RF). Relationships between MRI grey matter volumes and muscle areas or function tests were described using positive and negative regressions.

RESULTS

Twenty-six subjects (7 female, mean age 78.2 y, SD 5.0), 6 frail and 20 pre-frail were explored in this sub-study. Frail subjects had lower Mini Nutritional Assessment (MNA), Short Physical Performance Battery (SPPB), hip flexor strength than pre-frail ones but similar BMI and balance. Total SPPB was positively related with hip flexor strength and maximal RF area. Balance SPPB sub-score was unrelated to strength or RF area. MNA score was correlated with hip flexor strength and to global grey matter but not to SPPB. Hip flexor strength was correlated with grey matter areas involved in motor control. Walking time was negatively and rising chair sub-score was positively associated with grey matter volumes of motor areas.

CONCLUSIONS

Sarcopenia features were more frequent in frail than prefrail subjects and were associated with decrease in grey matter volumes involved in motor control.

Diabetes technology: improving care, improving patient-reported outcomes and preventing complications in young people with Type 1 diabetes

With the evolution of diabetes technology, those living with Type 1 diabetes are given a wider arsenal of tools with which to achieve glycaemic control and improve patient-reported outcomes. Furthermore, the use of these technologies may help reduce the risk of acute complications, such as severe hypoglycaemia and diabetic ketoacidosis, as well as long-term macro- and microvascular complications. In addition, diabetes technology can have a beneficial impact on psychosocial health by reducing the burden of diabetes. Unfortunately, diabetes goals are often unmet and people with Type 1 diabetes too frequently experience acute and long-term complications of this condition, in addition to often having less than ideal psychosocial outcomes. Increasing realization of the importance of patient-reported outcomes is leading to diabetes care delivery becoming more patient-centred. Diabetes technology in the form of medical devices, digital health and big data analytics have the potential to improve clinical care and psychosocial support, resulting in lower rates of acute and chronic complications, decreased burden of diabetes care, and improved quality of life.

Levels of wound calprotectin and other inflammatory biomarkers aid in deciding which patients with a diabetic foot ulcer need antibiotic therapy (INDUCE study)

AIMS

Deciding if a diabetic foot ulcer is infected in a community setting is challenging without validated point-of-care tests. Four inflammatory biomarkers were investigated to develop a composite algorithm for mildly infected diabetic foot ulcers: venous white cell count, C-reactive protein (CRP) and procalcitonin, and a novel wound exudate calprotectin assay. Calprotectin is a marker of neutrophilic inflammation.

METHODS

In a prospective study, people with uninfected or mildly infected diabetic foot ulcers who had not received oral antibiotics in the preceding 2 weeks were recruited from community podiatry clinics for measurement of inflammatory biomarkers. Antibiotic prescribing decisions were based on clinicians' baseline assessments and participants were reviewed 1 week later; ulcer infection was defined by clinicians' overall impression from their two assessments.

RESULTS

Some 363 potential participants were screened, of whom 67 were recruited, 29 with mildly infected diabetic foot ulcers and 38 with no infection. One participant withdrew early in each group. Ulcer area was 1.32 cm² [interquartile range (IQR) 0.32-3.61 cm² ] in infected ulcers and 0.22 cm² (IQR 0.09-1.46 cm² ) in uninfected ulcers. Baseline CRP for mild infection was 9.00 mg/ml and 6.00 mg/ml for uninfected ulcers; most procalcitonin levels were undetectable. Median calprotectin level in infected diabetic foot ulcers was 1437 ng/ml and 879 ng/ml in uninfected diabetic foot ulcers. Area under the receiver operating characteristic curve for a composite algorithm incorporating calprotectin, CRP, white cell count and ulcer area was 0.68 (95% confidence intervals 0.52-0.82), sensitivity 0.64, specificity 0.81.

CONCLUSIONS

A composite algorithm including CRP, calprotectin, white cell count and ulcer area may help to distinguish uninfected from mildly infected diabetic foot ulcers. Venous procalcitonin is unhelpful for mild diabetic foot ulcer infection.

Fissure Seal or Fluoride Varnish? A Randomized Trial of Relative Effectiveness

Fissure sealant (FS) and fluoride varnish (FV) are effective in preventing dental caries when compared with a no-treatment control. However, the relative clinical effectiveness of these interventions is uncertain. The objective of the study was to compare the clinical effectiveness of FS and FV in preventing dental caries in first permanent molars (FPMs) in 6- to 7-y-olds. The study design was a randomized clinical trial, with 2 parallel arms. The setting was a targeted-population program that used mobile dental clinics in schools located within areas of high social and economic deprivation in South Wales. A total of 1,016 children were randomized 1:1 to receive either FS or FV. Resin-based FS was applied to caries-free FPMs and maintained at 6-mo intervals. FV was applied at baseline and at 6-mo intervals for 3 y. The main outcome measures were the proportion of children developing caries into dentine (D_4-6MFT) on any 1 of up to 4 treated FPMs after 36 mo. At 36 mo, 835 (82%) children remained: 417 in the FS arm and 418 in the FV arm. A smaller proportion of children who received FV ( n = 73, 17.5%) versus FS ( n = 82, 19.6%) developed caries into dentine on at least 1 FPM (odds ratio [OR] = 0.84; 95% CI, 0.59 to 1.21; P = 0.35), a nonstatistically significant difference between FS and FV treatments. The results were similar when the number of newly decayed teeth (OR = 0.86; 95% CI, 0.60 to 1.22) and tooth surfaces (OR = 0.85; 95% CI, 0.59 to 1.21) were examined. In a community oral health program, semiannual application of FV resulted in caries prevention that was not significantly different from that obtained by applying and maintaining FS after 36 mo (EudraCT: 2010-023476-23; ISRCTN: ISRCTN17029222).

Measuring Alcohol Marketing Engagement: The Development and Psychometric Properties of the Alcohol Marketing Engagement Scale

Ample evidence exists in support of the influence of media, both traditional and electronic, on perceptions and engagement with alcohol marketing. We describe the development, calibration, and evidence for technical quality and utility for a new measure, the Alcohol Marketing Engagement Scale. Using two samples of college undergraduates (n1 = 199, n2 = 732), we collected field test responses to a total of 13 items. Initial support for scale validity is presented via correlations with attributes previously shown to be related to alcohol engagement. While the joint map of estimated scale locations of items and respondents indicates the need for further scale development, the results of the present analyses are promising. Implications for use in research are discussed.

The societal cost of Huntington's disease: are we underestimating the burden?

Background and purpose

Approximately 9000 people in the UK are affected by Huntington's disease (HD). People with HD require ongoing health and social care support. There is a knowledge gap about costs of health and social care use associated with HD in the UK. This paper estimates the economic cost in the UK.

Methods

Data on UK patients for the year 2013 were extracted from the European Huntington's Disease Network REGISTRY study, a full clinical dataset, including the full medical history and medication history for patients with HD. National unit costs for the price year 2013 were applied to health and social care services.

Results

Data were available for 131 people. The mean annual cost per person with HD was £21 605. The largest proportion of this cost (65%) was due to informal care (£14 085).

Conclusions

Informal care was the largest driver of costs across all stages of HD; thus there is a need to also consider the needs of carers when planning services for people with HD.

Interventions for hidradenitis suppurativa: a Cochrane systematic review incorporating GRADE assessment of evidence quality

More than 50 interventions have been used to treat hidradenitis suppurativa (HS), and so therapy decisions can be challenging. Our objective was to summarize and appraise randomized controlled trial (RCT) evidence for HS interventions in adults. Searches were conducted in Medline, Embase, CENTRAL, LILACS, five trials registers and abstracts from eight dermatology conferences until 13 August 2015. Two review authors independently assessed study eligibility, extracted data and assessed methodological quality. Primary outcomes were quality of life and adverse effects of the interventions. Twelve trials, from 1983 to 2015, investigating 15 different interventions met our inclusion criteria. The median trial duration was 16 weeks and the median number of participants was 27. Adalimumab 40 mg weekly improved the Dermatology Life Quality Index (DLQI) by 4·0 points, which equates to the minimal clinically important difference for the scale, compared with placebo (95% confidence interval -6·5 to -1·5 points). Evidence quality was reduced to 'moderate' because the results are based on only a single study. Adalimumab 40 mg every other week was ineffective in a meta-analysis of two studies comprising 124 participants. Infliximab 5 mg kg(-1) improved the DLQI score by 8·4 points after 8 weeks in a moderate-quality study completed by 33 of 38 participants. Etanercept 50 mg twice weekly was ineffective. Inclusion of a gentamicin sponge prior to primary closure did not improve outcomes. Other interventions, including topical and oral antibiotics, were investigated by relatively small studies, preventing treatment recommendations due to imprecision. More, larger RCTs are required to investigate most HS interventions, particularly oral treatments and surgical therapy. Moderate-quality evidence suggests that adalimumab given weekly and infliximab are effective, whereas adalimumab every other week is ineffective.

'It's made all of us bond since that course…' - a qualitative study of service users' experiences of a CBT anger management group intervention

BACKGROUND

People with intellectual disabilities (ID) are rarely asked about their experiences as users of psychological services and little is known about the views of clients with ID who have undergone cognitive behavioural therapy (CBT). This study aimed to gather the views of adults with ID who had recently taken part in a cluster randomised control trial (RCT) of a staff-delivered manualised CBT anger management group intervention.

METHOD

A qualitative method, Interpretative Phenomenological Analysis (IPA), was employed and eleven participants were interviewed. The interviews took place after the intervention, within two weeks of the end of the group, to gain an understanding of service users' experiences of participating in a CBT group.

RESULTS

IPA of the interview transcripts indicated that the intervention was experienced as effective and enjoyable and a number of themes were identified including: 'the importance of relationships', 'a new me', 'new and improved relationships', 'presenting myself in a positive light' and 'what the group didn't change'.

CONCLUSIONS

The results will be discussed in the context of applying group CBT for adults with ID and implications for service development.

Cognitive behavioural anger management intervention for people with intellectual disabilities: costs of intervention and impact on health and social care resource use

BACKGROUND

Anger and aggression among adults with intellectual disability (ID) are associated with a range of adverse consequences for their well-being and that of their family or staff carers. The aims were to evaluate the effectiveness of an anger management intervention for adults with mild to moderate ID and to evaluate the costs of the intervention and its impact on health and social care resource use. This paper is concerned with the latter aim.

METHODS

A cluster-randomised controlled trial was conducted involving day services for adults with ID in Scotland, England and Wales. Incremental costs of delivering the intervention and its impact on subsequent total health and social care package costs were calculated. Full data comparing costs between baseline and follow-up 10 months later were collected for 67 participants in the intervention arm and 62 participants in the control arm. Cost differences between the groups at follow-up, adjusted for baseline levels, were calculated using non-parametric bootstrapping controlling for clustering.

RESULTS

The mean hourly excess cost of intervention over treatment as usual was £12.34. A mean adjusted cost difference of £22.46 per person per week in favour of the intervention group was found but this was not statistically significant.

CONCLUSIONS

The baseline-adjusted cost difference at follow-up would result in a fairly immediate compensation for the excess costs of intervention, provided the difference is not a statistical artefact. Further research is needed to clarify the extent to which it might represent a real saving in service support costs.

Calculated globulin (CG) as a screening test for antibody deficiency

Calculated globulin (total protein - albumin) is usually tested as part of a liver function test profile in both primary and secondary care and determines the serum globulin concentration, of which immunoglobulins are a major component. The main use hitherto of calculated globulin is to detect paraproteins when the level is high. This study investigated the potential to use low levels of calculated globulin to detect antibody deficiency. Serum samples with calculated globulin cut-off < 18 g/l based on results of a pilot study were collected from nine hospitals in Wales over a 12-month period. Anonymized request information was obtained and the samples tested for immunoglobulin levels, serum electrophoresis and, if appropriate, immunofixation. A method comparison for albumin measurement using bromocresol green and bromocresol purple was undertaken. Eighty-nine per cent (737 of 826) samples had an immunoglobulin (Ig)G level of < 6 g/l using the bromocresol green methodology with a cut-off of < 18 g/l, and 56% (459) had an IgG of < 4 g/l. Patients with both secondary and primary antibody deficiency were discovered and serum electrophoresis and immunofixation showed that 1·2% (10) had previously undetected small paraproteins associated with immune-paresis. Using bromocresol purple, 74% of samples had an IgG of < 6 g/l using a cut-off of < 23 g/l. Screening using calculated globulin with defined cut-off values detects both primary and secondary antibody deficiency and new paraproteins associated with immune-paresis. It is cheap, widely available and under-utilized. Antibody-deficient patients have been discovered using information from calculated globulin values, shortening diagnostic delay and time to treatment with immunoglobulin replacement therapy.

MAGNEsium Trial In Children (MAGNETIC): a randomised, placebo-controlled trial and economic evaluation of nebulised magnesium sulphate in acute severe asthma in children

BACKGROUND

There are few data on the role of nebulised magnesium sulphate (MgSO4) in the management of acute asthma in children. Those studies that have been published are underpowered, and use different methods, interventions and comparisons. Thus, no firm conclusions can be drawn.

OBJECTIVES

Does the use of nebulised MgSO4, when given as an adjunct to standard therapy in acute severe asthma in children, result in a clinical improvement when compared with standard treatment alone?

DESIGN

Patients were randomised to receive three doses of MgSO4 or placebo, each combined with salbutamol and ipratropium bromide, for 1 hour. The Yung Asthma Severity Score (ASS) was measured at baseline, randomisation, and at 20, 40, 60 (T60), 120, 180 and 240 minutes after randomisation.

SETTING

Emergency departments and children's assessment units at 30 hospitals in the UK.

PARTICIPANTS

Children aged 2-15 years with acute severe asthma.

INTERVENTIONS

Patients were randomised to receive nebulised salbutamol 2.5 mg (ages 2-5 years) or 5 mg (ages ≥ 6 years) and ipratropium bromide 0.25 mg mixed with either 2.5 ml of isotonic MgSO4 (250 mmol/l, tonicity 289 mOsm; 151 mg per dose) or 2.5 ml of isotonic saline on three occasions at approximately 20-minute intervals.

MAIN OUTCOME MEASURES

The primary outcome measure was the ASS after 1 hour of treatment. Secondary measures included 'stepping down' of treatment at 1 hour, number and frequency of additional salbutamol administrations, length of stay in hospital, requirement for intravenous bronchodilator treatment, and intubation and/or admission to a paediatric intensive care unit. Data on paediatric quality of life, time off school/nursery, health-care resource usage and time off work were collected 1 month after randomisation.

RESULTS

A total of 508 children were recruited into the study; 252 received MgSO4 and 256 received placebo along with the standard treatment. There were no differences in baseline characteristics. There was a small, but statistically significant difference in ASS at T60 in those children who received nebulised MgSO4 {0.25 [95% confidence interval (CI) 0.02 to 0.48]; p = 0.034} and this difference was sustained for up to 240 minutes [0.20 (95% CI 0.01 to 0.40), p = 0.042]. The clinical significance of this gain is uncertain. Assessing treatment-covariate interactions, there is evidence of a larger effect in those children with more severe asthma exacerbations ( p = 0.034) and those with a shorter duration of symptoms ( p = 0.049). There were no significant differences in the secondary outcomes measured. Adverse events (AEs) were reported in 19% of children in the magnesium group and 20% in the placebo group. There were no clinically significant serious AEs in either group. The results of the base-case economic analyses are accompanied by considerable uncertainty, but suggest that, from an NHS and Personal Social Services perspective, the addition of magnesium to standard treatment may be cost-effective compared with standard treatment only. The results of economic evaluation show that the probability of magnesium being cost-effective is over 60% at cost-effectiveness thresholds of £1000 per unit decrement in ASS and £20,000 per quality-adjusted life-year (QALY) gained, respectively; it is noted that for some parameter variations this probability is much lower, reflecting the labile nature of the cost-effectiveness ratio in light of the small differences in benefits and costs shown in the trial and the relation between the main outcome measure (ASS) and preference based measures of quality of life used in cost-utility analysis (European Quality of Life-5 Dimensions; EQ-5D).

CONCLUSIONS

This study supports the use of nebulised isotonic MgSO4 at the dose of 151 mg given three times in the first hour of treatment as an adjuvant to standard treatment when a child presents with an acute episode of severe asthma. No harm is done by adding magnesium to salbutamol and ipratropium bromide, and in some individuals it may be clinically helpful. The response is likely to be more marked in those children with more severe attacks and with a shorter duration of exacerbation. Although the study was not powered to demonstrate this fully, the data certainly support the hypotheses that nebulised magnesium has a greater clinical effect in children who have more severe exacerbation with shorter duration of symptoms.

A cluster randomised controlled trial of a manualised cognitive behavioural anger management intervention delivered by supervised lay therapists to people with intellectual disabilities

BACKGROUND

Anger is a frequent problem for many people with intellectual disabilities, and is often expressed as verbal and/or physical aggression. Cognitive-behaviour therapy (CBT) is the treatment of choice for common mental health problems, but CBT has only recently been adapted for people with intellectual disabilities. Anger is the main psychological presentation in which controlled trials have been used to evaluate CBT interventions for people with intellectual disabilities but these do not include rigorous randomised studies.

OBJECTIVES

To evaluate (1) the impact of a staff-delivered manualised CBT anger management intervention on (a) reported anger among people with mild to moderate intellectual disabilities, and (b) anger coping skills, aggression, mental health, quality of life and costs of health and social care; (2) factors that influence outcome; and (3) the experience of service users, lay therapists and service managers.

DESIGN

A cluster randomised controlled trial based on 30 day centres (15 intervention and 15 control). Intention-to-treat comparisons of outcomes used a two-level linear regression model to allow for clustering within centres with baseline outcome levels as a covariate. Comparison of cost data used non-parametric bootstrapping. Qualitative analysis used interpretative phenomenological analysis and thematic analysis.

SETTING

Recruited day centres had four-plus service users with problem anger who were prepared to participate, two-plus staff willing to be lay therapists, a supportive manager and facilities for group work, and no current anger interventions.

PARTICIPANTS

A total of 212 service users with problem anger were recruited. Thirty-three were deemed ineligible (30 could not complete assessments and three withdrew before randomisation). Retention at follow-up was 81%, with 17 withdrawals in each arm. Two to four staff per centre were recruited as lay therapists. Eleven service users, nine lay therapists and eight managers were interviewed.

INTERVENTIONS

The manualised intervention comprised 12 weekly 2-hour group sessions supplemented by 'homework'. Lay therapists received training and ongoing supervision from a clinical psychologist. Treatment fidelity, group attendance and resources used in intervention delivery were monitored.

MAIN OUTCOME MEASURES

The primary outcome was the service user-rated Provocation Index (PI), a measure of response to hypothetical situations that may provoke anger. Secondary trial outcomes were the key worker-rated PI; the service user- and key worker-rated Profile of Anger Coping Skills (PACS); the service user-rated PACS imaginal provocation test (PACS-IPT), a measure of response to actual situations known to provoke anger; aggression; mental health; self-esteem; quality of life; and health and social care resource use. Assessments were administered before randomisation and at 16 weeks and 10 months after randomisation.

RESULTS

Fourteen treatment groups were delivered, each with 12 sessions lasting an average of 114 minutes, with a mean of 4.9 service users and 2.0 lay therapists. The mean hourly cost per service user was £ 25.26. The mean hourly excess cost over treatment as usual was £ 12.34. There was no effect of intervention on the primary outcome - self-rated PI. There was a significant impact on the following secondary outcomes at the 10-month follow-up: key worker-rated PI, self-rated PACS-IPT and self- and key worker-rated PACS. Key workers and home carers reported significantly lower aggression at 16 weeks, but not at 10 months. There was no impact on mental health, self-esteem, quality of life or total cost of health and social care. Service users, key workers and service managers were uniformly positive.

CONCLUSIONS

The intervention was effective at changing anger coping skills and staff-rated anger. Impact on self-rated anger was equivocal. With hindsight there are reasons, from an analysis of factors influencing outcomes, to think that self-rated PI was not a well-chosen primary outcome. Widespread implementation of manualised lay therapist-led but psychologist-supervised anger management CBT for people with mild to moderate intellectual disabilities is recommended.

An observational study of cognitive function in patients with irritable bowel syndrome and inflammatory bowel disease

BACKGROUND

Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) are associated with several risk factors for developing cognitive impairment. These include altered cytokine levels, concurrent mood disorders, and the presence of chronic pain. This observational study aimed to explore the cognitive profile of patients with these conditions.

METHODS

Participants completed the Cardiff Cognitive Battery, a series of computerized neuropsychological performance tests that examine a range of cognitive function including psychomotor speed, memory, and intelligence. A progressive analysis of covariance model was used with demographic details, anxiety and depression scores entered as covariates. Fecal calprotectin levels were measured in IBD patients to determine disease activity.

KEY RESULTS

In total 231 participants were recruited (150 IBD patients, 40 IBS patients, and 41 healthy controls). IBD patients had significantly lower scores on fluid (p = 0.01) and crystalline intelligence tests (p = 0.028) compared to healthy volunteers, however, this reflected differences in concurrent mood disorder and level of education. When these factors were added as covariates, there was no significant difference between the groups. Duration and activity of disease did not affect cognitive function in IBD patients. Severity of symptoms had no impact on cognition in patients with IBS.

CONCLUSIONS & INFERENCES

The results of this observational study do not support the hypothesis that IBS or IBD have an intrinsic disease process that is associated with cognitive dysfunction. It is possible that concurrent mood disorders, in particular depression, may affect the cognitive performance of patients with IBD in specific tasks.

Symptoms of irritable bowel syndrome in patients with inflammatory bowel disease: examining the role of sub-clinical inflammation and the impact on clinical assessment of disease activity

BACKGROUND

Symptoms compatible with irritable bowel syndrome (IBS) are frequently present in patients with inflammatory bowel disease (IBD); however, the cause of this phenomenon is unclear.

AIM

To determine the different contributions of 'true IBS' and sub-clinical inflammation in producing IBS-type symptoms in IBD patients, and to ascertain the impact these symptoms have on the clinical assessment of IBD activity.

METHODS

In this cross-sectional study, 169 IBD patients completed questionnaires to assess disease activity, presence of IBS-type symptoms, and levels of anxiety and depression. Stool samples were collected for analysis of faecal calprotectin (FC).

RESULTS

IBS-type symptoms were significantly more common in female patients (OR = 4.64, 1.55-13.88) and were associated with higher levels of anxiety (OR = 1.11, 1.01-1.21). There was no statistical difference between the FC levels of patients in clinical remission with IBS-type symptoms compared with those without (median values = 111 μg/g vs. 45.5 μg/g respectively, P = 0.171). The prevalence of IBS-type symptoms in patients with a normal FC level was 31%.

CONCLUSIONS

A substantial number of IBD patients with normal faecal calprotectin level experience IBS-type symptoms. These patients exhibit similar features to people diagnosed with IBS in the general community, suggesting that the conditions are not mutually exclusive and may coexist in a considerable number of IBD patients. A systematic diagnostic approach is required to assess IBD patients with IBS-type symptoms as sub-clinical inflammation may play a role in a proportion of cases.

How death anxiety impacts nurses' caring for patients at the end of life: a review of literature

Nurses are frequently exposed to dying patients and death in the course of their work. This experience makes individuals conscious of their own mortality, often giving rise to anxiety and unease. Nurses who have a strong anxiety about death may be less comfortable providing nursing care for patients at the end of their life. This paper explores the literature on death anxiety and nurses’ attitudes to determine whether fear of death impacts on nurses’ caring for dying patients. Fifteen quantitative studies published between 1990 and 2012 exploring nurses’ own attitudes towards death were critically reviewed. Three key themes identified were: i). nurses’ level of death anxiety; ii). death anxiety and attitudes towards caring for the dying, and iii). death education was necessary for such emotional work. Based on quantitative surveys using valid instruments, results suggested that the level of death anxiety of nurses working in hospitals in general, oncology, renal, hospice care or in community services was not high. Some studies showed an inverse association between nurses’ attitude towards death and their attitude towards caring for dying patients. Younger nurses consistently reported stronger fear of death and more negative attitudes towards end-of-life patient care. Nurses need to be aware of their own beliefs. Studies from several countries showed that a worksite death education program could reduce death anxiety. This offers potential for improving nurses’ caring for patients at the end of their life.

Stress Among African American Emerging Adults: The Role of Family and Cultural Factors

The aim of this study was to examine the effects of family and cultural variables on stress among African American emerging adults. Data from this study was collected as part of a larger study that examined cultural, family, and contextual factors and smoking among African American youth in 5th, 8th, and 12th grades. Data were collected from high school seniors at the end of their 12th grade year and 6 months post high school. Multiple regression analyses were conducted to determine whether racial identity, family cohesion, and parental monitoring influence students' perceived frequency of stress. Higher levels of racial identity were associated with more perceived stress. There were no significant main effects for either parental monitoring or family cohesion on stress. There were significant interactions between racial identity and parental monitoring and between parental monitoring and family cohesion. Study implications are discussed regarding the importance of stress reduction programs for African American emerging adults and for parents of these adults.

Abstract PD07-09: Zoledronate versus ibandronate comparative evaluation (ZICE) trial - first results of a UK NCRI 1,405 patient phase III trial comparing oral ibandronate versus intravenous zoledronate in the treatment of breast cancer patients with bone metastases

Introduction Bone metastases in patients with breast cancer have serious effects on health including pain, poor mobility, skeletal fractures, spinal cord compression and the need for radiotherapy/surgery. The introduction of intravenous (IV) bisphosphonates, such as zoledronic acid (Z) has significantly delayed the onset of skeletal-related events (SRE). However, prolonged IV bisphosphonates place burdens upon patient and hospital, and can also cause renal and acute phase toxicities. Ibandronic acid (I), a third generation amino-bisphosphonate in its oral form has previously been compared with placebo and was shown to be well tolerated and effective. Indirect comparisons with IV Z indicated similar efficacy in reducing bone events, but adverse events were overall comparable with placebo. One might therefore assume that oral ibandronate would be more acceptable to patients, and the ZICE Trial is the only large scale direct randomised comparison between IV Z and oral I to report.

Methods Between January 2006 and October 2010, 1405 newly diagnosed metastatic breast cancer patients with proven bone metastases were randomised 1:1 to IV Z (4mg 15 min infusion every 3–4 weeks) or oral I (50mg per day) for up to 96 weeks. All patients were prescribed daily calcium & vitamin D supplementation, and patients with current active dental problems including infection were excluded. Patients also received chemotherapy, and or endocrine therapy as determined by their physician. The primary objective was to demonstrate non-inferiority of oral I in comparison with IV Z in terms of the SRE rate, defined as the number of SREs reported per year (using multiple event analysis). Secondary endpoints included time to 1st SRE, proportion of patients with SRE, Pain Scores, side effect profiles including ONJ and renal toxicities, quality of life and Health resources and overall survival. The trial was run under the auspices of the NCRI, sponsored by Velindre NHS Trust, coordinated by the Wales Cancer Trials Unit, funded by an educational grant from Roche and peer reviewed/endorsed by Cancer Research UK (CRUKE/04/022).

Results At the time of this analysis the last randomised patient had completed 96 weeks of therapy, median follow up was 18.4 months and total number of SREs was 865 (468 in I and 397 in Z). For the primary objective, the SRE rate was 0.543 and 0.444 in I and Z groups respectively (Hazard ratio, 1.22; 95% CI, 1.04 to 1.45; P = .017). Ibandronate failed to meet the criteria for non-inferiority to Zoledronate, but was similar in delaying time to first SRE (hazard ratio, 1.11; 95% CI, 0.94 to 1.31; P = .233). Overall survival (disease progression), was very similar between groups but renal AEs occurred more frequently with Z than I; Compliance with oral therapy was 82%. ONJ rate was very low in both arms (0.71%, I; 1.29%, Z; P = 0.28).

Conclusion Oral I is inferior to Z in terms of the SRE rate in metastatic breast cancer patients with bone metastases, but is similar to Z in delaying time to first SRE. Both drugs had acceptable safety profiles, with adverse events consistent with those reported previously.

The effect of waiting times from general practitioner referral to MRI or orthopaedic consultation for the knee on patient-based outcomes

OBJECTIVES

The purpose of this study was to test for the effect of waiting time from general practitioner (GP) referral to MRI or to orthopaedic consultation on outcomes of patients with knee problems, and to test whether any characteristics of trial participants predicted waiting time to MRI or orthopaedics.

METHODS

We undertook secondary analyses of data on 553 participants from a randomised trial who were recruited from 163 general practices during November 2002 to October 2004.

RESULTS

Of the patients allocated to MRI, 263 (94%) had an MRI, and of those referred to orthopaedics, 236 (86%) had an orthopaedic consultation. The median (interquartile range) waiting time in days from randomisation to MRI was 41.0 (21.0-71.0) and to orthopaedic appointment was 78.5 (54.5-167.5). Waiting time was found to have no significant effect on patient outcome for both the Short Form 36-item (SF-36) physical functioning score (p=0.570) and the Knee Quality of Life 26-item (KQoL-26) physical functioning score (p=0.268). There was weak evidence that males waited less time for their MRI (p=0.049) and older patients waited longer for their orthopaedic referral (p=0.049). For patients who resided in the catchment areas of some centres there were significantly longer waiting times for both MRI and orthopaedic appointment.

CONCLUSION

Where patients reside is a strong predictor of waiting time for access to services such as MRI or orthopaedics. There is no evidence to suggest, however, that this has a significant effect on physical well-being in the short term for patients with knee problems.

Predicting benign course and prolonged illness in lower respiratory tract infections: a 13 European country study

BACKGROUND

Clinicians and patients are often uncertain about the likely clinical course of community-acquired lower respiratory tract infection (LRTI) in individual patients. We therefore set out to develop a prediction rule to identify patients at risk of prolonged illness and those with a benign course.

METHODS

We determined which signs and symptoms predicted prolonged illness (moderately bad symptoms lasting >3 weeks after consultation) in 2690 adults presenting in primary care with LRTI in 13 European countries by using multilevel modelling.

RESULTS

212 (8.1%) patients experienced prolonged illness. Illness that had lasted >5 days at the time of presentation, >1 episode of cough in the preceding year, chronic use of inhaled pulmonary medication and diarrhoea independently predicted prolonged illness. Applying a rule based on these four variables, 3% of the patients with ≤ 1 variable present (n = 955, 37%) had prolonged illness. Patients with all four variables present had a 30% chance of prolonged illness (n = 71, 3%).

CONCLUSIONS

Most patients with acute cough (>90%) recover within 3 weeks. A prediction rule containing four clinical items had predictive value for the risk of prolonged illness, but given its imprecision, appeared to have little clinical utility. Patients should be reassured that they are most likely to recover within three weeks and advised to re-consult if their symptoms persist beyond that period.

Development and evaluation by a cluster randomised trial of a psychosocial intervention in children and teenagers experiencing diabetes: the DEPICTED study

OBJECTIVE

To develop and evaluate a health-care communication training programme to help diabetes health-care professionals (HCPs) counsel their patients more skilfully, particularly in relation to behaviour change.

DESIGN

The HCP training was assessed using a pragmatic, cluster randomised controlled trial. The primary and secondary analyses were intention-to-treat comparisons of outcomes using multilevel modelling to allow for cluster (service) and individual effects, and involved two-level linear models.

SETTING

Twenty-six UK paediatric diabetes services.

PARTICIPANTS

The training was delivered to HCPs (doctors, nurses, dietitians and psychologists) working in paediatric diabetes services and the effectiveness of this training was measured in 693 children aged 4-15 years and families after 1 year (95.3% follow-up).

INTERVENTIONS

A blended learning programme was informed by a systematic review of the literature, telephone and questionnaire surveys of professional practice, focus groups with children and parents, experimental consultations and three developmental workshops involving a stakeholder group. The programme focused on agenda-setting, flexible styles of communication (particularly guiding) and a menu of strategies using web-based training and practical workshops.

MAIN OUTCOME MEASURES

The primary trial outcome was a change in glycosylated haemoglobin (HbA1c) levels between the start and finish of a 12-month study period. Secondary trial outcomes included change in quality of life, other clinical [including body mass index (BMI)] and psychosocial measures (assessed at participant level as listed above) and cost (assessed at service level). In addition, patient details (HbA1c levels, height, weight, BMI, insulin regimen), health service contacts and patient-borne costs were recorded at each clinic visit, along with details of who patients consulted with, for how long, and whether or not patients consulted on their own at each visit. Patients and carers were also asked to complete an interim questionnaire assessing patient enablement (or feelings towards clinic visit for younger patients aged 7-10 years) at their first clinic visit following the start of the trial. The cost of the intervention included the cost of training intervention teams.

RESULTS

Trained staff showed better skills than control subjects in agenda-setting and consultation strategies, which waned from 4 to 12 months. There was no effect on HbA1c levels (p = 0.5). Patients in intervention clinics experienced a loss of confidence in their ability to manage diabetes, whereas controls showed surprisingly reduced barriers (p = 0.03) and improved adherence (p = 0.05). Patients in intervention clinics reported short-term increased ability (p = 0.04) to cope with diabetes. Parents in the intervention arm experienced greater excitement (p = 0.03) about clinic visits and improved continuity of care (p = 0.01) without the adverse effects seen in their offspring. The mean cost of training was £13,145 per site or £2163 per trainee. There was no significant difference in total NHS costs (including training) between groups (p = 0.1).

CONCLUSIONS

Diabetes HCPs can be trained to improve consultation skills, but these skills need reinforcing. Over 1 year, no benefits were seen in children, unlike parents, who may be better placed to support their offspring. Further modification of this training is required to improve outcomes that may need to be measured over a longer time to see effects.

Antibiotic prescribing for adults with acute cough/lower respiratory tract infection: congruence with guidelines

European guidelines for treating acute cough/lower respiratory tract infection (LRTI) aim to reduce nonevidence-based variation in prescribing, and better target and increase the use of first-line antibiotics. However, their application in primary care is unknown. We explored congruence of both antibiotic prescribing and antibiotic choice with European Respiratory Society (ERS)/European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines for managing LRTI. The present study was an analysis of prospective observational data from patients presenting to primary care with acute cough/LRTI. Clinicians recorded symptoms on presentation, and their examination and management. Patients were followed up with self-complete diaries. 1,776 (52.7%) patients were prescribed antibiotics. Given patients' clinical presentation, clinicians could have justified an antibiotic prescription for 1,915 (71.2%) patients according to the ERS/ESCMID guidelines. 761 (42.8%) of those who were prescribed antibiotics received a first-choice antibiotic (i.e. tetracycline or amoxicillin). Ciprofloxacin was prescribed for 37 (2.1%) and cephalosporins for 117 (6.6%). A lack of specificity in definitions in the ERS/ESCMID guidelines could have enabled clinicians to justify a higher rate of antibiotic prescription. More studies are needed to produce specific clinical definitions and indications for treatment. First-choice antibiotics were prescribed to the minority of patients who received an antibiotic prescription.

"I have always believed I was at high risk..." The role of expectation in emotional responses to the receipt of an average, moderate or high cancer genetic risk assessment result: a thematic analysis of free-text questionnaire comments

It is well-recognised that receipt of cancer genetic risk information can evoke a mix of both positive and negative emotional responses. Objective risk itself is not necessarily predictive of emotional response to receipt of risk information and the Cue Adaptive Reasoning Account (CARA; Renner, 2004) suggests that that the degree to which level of risk is consistent with expectations may influence emotional responses. This paper reports a thematic analysis of the free-text data structured around responses to the three risk labels: average, moderate or high. Data is reported from both 123 women and 15 men, including those with a past or current cancer diagnosis. Reactions to risk information appear to be dependent upon participants' pre-conceived expectations about their level of cancer risk. Many average risk respondents questioned the accuracy of their result, whereas high risk information was often expected. Findings are discussed in relation to the CARA model and clinical implications.

The development of a cancer genetic-specific measure of coping: the GRACE

OBJECTIVE

Generic measures of coping fail to capture the process of undergoing specific health processes such as cancer genetic risk assessment. The Genetic Risk Assessment Coping Evaluation (GRACE) has been developed to provide greater specificity of measurement.

METHOD

Based upon previous research findings, the GRACE measures the degree of stress associated with 11 recognised sources of stress for individuals undergoing the early stages of cancer genetic risk assessment, and the use of up to eight coping strategies they may elicit. This paper reports preliminary data from the piloting of the GRACE within a randomised trial of a coping intervention.

RESULTS

Of the 265 participants who completed and returned their baseline questionnaire (prior to being informed of their level of genetic risk), 257 completed the GRACE. The most highly endorsed sources of stress involved concerns relating to family members, endorsed by over 60% of respondents, and concerns about how the participants would cope if found to be at increased risk (59%). Participants made use of multiple coping strategies across different sources of stress. The most frequently reported coping strategies were emotion-focused, which may reflect the stage of the assessment process.

CONCLUSION

The completion rates for the matrix and specificity of responses provided suggest that the GRACE may be an acceptable measurement tool. Further data collection and validation is ongoing.

The evolution of worry after breast cancer risk assessment: 6-year follow-up of the TRACE study cohort

OBJECTIVES

There is little evidence regarding the long-term psychological implications of breast cancer risk assessment for women at moderate genetic risk. A follow-up study of a trial cohort was conducted to evaluate psychological outcomes and their predictors at 6-year follow-up. A further aim was to examine threshold scores for high cancer worry.

METHODS

Questionnaires were sent to 384 women assessed as moderate risk during a UK trial of genetic assessment (TRACE). Measures included cancer worry, perceived risk, health behaviours, general anxiety, psychological morbidity, optimism, and background variables assessed during TRACE and at 6-year follow-up.

RESULTS

Reductions from baseline cancer worry and breast self-examination (BrSE) frequency were maintained 6 years after risk assessment, with relatively consistent levels over short- and long-term follow-up. Provision of risk information led to short-term reductions in perceived risk. During the 6-year period, 43% of women reported having made lifestyle changes and 27% had requested a mammogram. Baseline and post-risk cancer worry were the only significant predictors of long-term cancer worry. Greater worry at baseline predicted more frequent BrSE and higher perceived risk, but not lifestyle change or mammogram requests, at 6 years. Eighteen percent of women reported cancer worry above a threshold of 12.5 at long-term follow-up, compared with 30% at baseline.

CONCLUSIONS

Overall reductions in cancer worry following moderate risk assessment were maintained in the long term. However, women at risk of sustained high cancer worry should be identified at an early stage in the risk assessment process for more intensive psycho-educational intervention.
