Barriers and facilitators to implementing screening and brief intervention for alcohol misuse: a systematic review of qualitative evidence

BACKGROUND This review aimed to synthesize qualitative evidence for barriers and facilitators to effective implementation of screening and brief intervention for alcohol misuse in adults and children over 10 years. METHODS A search of medical and social science databases was carried out and augmented by hand-searching of reference lists and contents of key journals. Qualitative evidence was synthesized thematically. RESULTS A total of 47 papers varying in design and quality were included in the review. Most evaluated implementation in primary care settings. Implementation was reported to be limited by lack of resources, training and support from management, as well as workload. The appropriateness of context in which discussions take place was reported as an acceptability factor for patients and practitioners. Health professionals require sufficient knowledge about alcohol guidelines and risk in order to implement screening and intervention to those most in need. CONCLUSIONS Whilst brief screening and brief intervention have been shown to be effective in some settings, this review has identified a number of barriers and facilitators to implementation. Adequate resources, training and the identification of those at risk without stereotyping are the main facilitators in primary care. More research is needed to assess implementation in other settings.

Behavioural interventions for weight management in pregnancy: A systematic review of quantitative and qualitative data

BackgroundThere is a rising prevalence of excessive weight gain in pregnancy and an increasing number of pregnant women who are overweight or obese at the start of the pregnancy. Excessive weight gain during pregnancy is associated with adverse maternal and neonatal consequences and increases the risk of long-term obesity. Pregnancy therefore may be a key time to prevent excessive weight gain and improve the health of women and their unborn child. This systematic review sought to assess the effectiveness of behavioural interventions to prevent excessive weight gain in pregnancy and explore the factors that influence intervention effectiveness.MethodsWe undertook a systematic review of quantitative and qualitative evidence. This included a meta-analysis of controlled trials of diet and physical activity interventions to prevent excessive weight gain during pregnancy and a thematic synthesis of qualitative studies that investigated the views of women on weight management during pregnancy. A thorough search of eleven electronic bibliographic databases, reference lists of included studies, relevant review articles and experts in the field were contacted to identify potentially relevant studies.Two independent reviewers extracted data. RevMan software was used to perform the meta-analyses. Qualitative data was subject to thematic analysis. Both quantitative and qualitative data were aligned using a matrix framework.ResultsFive controlled trials and eight qualitative studies were included. The overall pooled effect size found no significant difference in gestational weight gain amongst participants in the intervention group compared with the control group (mean difference -0.28 95% CI -0.64 to 0.09). The study designs, participants and interventions all varied markedly and there was significant heterogeneity within this comparison in the meta-analysis (I2 67%). Subgroup and sensitivity analysis did not identify contextual elements that influenced the effectiveness of the intervention.In a thematic analysis of the qualitative studies, three major themes emerged relating to womens views of weight management in pregnancy: pregnancy as a time of transition and change, conflicting and contradictory messages and a perceived lack of control. When the results of both quantitative and qualitative data were aligned it was clear that some of the barriers that women described in achieving healthy weight gain in pregnancy were not addressed by the interventions evaluated. This may have contributed to the limited effectiveness of the interventions.ConclusionsDespite intense and often tailored interventions there was no statistically significant effect on weight gain during pregnancy. Inadequate and often contradictory information regarding healthy weight management was reported by women in qualitative studies and this was addressed in the interventions but this in itself was insufficient to lead to reduced weight gain. Multiple types of interventions, including community based strategies are needed to address this complex health problem.

The role of advanced practice nurses in knowledge brokering as a means of promoting evidence-based practice among clinical nurses.

AIM To identify approaches used by advanced practice nurses to promote evidence-based practice among clinical nurses. BACKGROUND Barriers encountered at individual and organizational levels hinder clinical nurses in their ability to deliver evidence-based practice. Advanced practice nurses are well placed to promote evidence-based practice through interactions with clinical nurses. However, little is understood about how advanced practice nurses might realize this potential. METHOD A multiple instrumental case study of 23 advanced practice nurses from hospital and primary care settings across seven Strategic Health Authorities in England was undertaken in 2006. Data collection comprised interviews and observation of advanced practice nurses and interviews with clinical nurses and other healthcare professionals. Data were analysed using the Framework approach. FINDINGS Advanced practice nurses acted as knowledge brokers in promoting evidence-based practice among clinical nurses. Knowledge management and promoting the uptake of knowledge were key components of knowledge brokering. Knowledge management involved generating different types of evidence, accumulating evidence to act as a repository for clinical nurses, synthesizing different forms of evidence, translating evidence by evaluating, interpreting and distilling it for different audiences and disseminating evidence by formal and informal means. Advanced practice nurses promoted the uptake of evidence by developing the knowledge and skills of clinical nurses through role modelling, teaching, clinical problem-solving and facilitating change. CONCLUSION The role of advanced practice nurses in knowledge brokering is complex and multi-faceted. It extends beyond the knowledge management, linkage and capacity building identified in the literature to include active processes of problem-solving and facilitating change.

Stakeholders' views of UK nurse and pharmacist supplementary prescribing

Objectives: Supplementary prescribing (SP) by pharmacists and nurses in the UK represents a unique approach to improving patients’ access to medicines and better utilizing health care professionals’ skills. Study aims were to explore the views of stakeholders involved in SP policy, training and practice, focusing upon issues such as SP benefits, facilitators, challenges, safety and costs, thereby informing future practice and policy. Method: Qualitative, semi-structured interviews were conducted with 43 purposively sampled UK stakeholders, including pharmacist and nurse supplementary prescribers, doctors, patient groups representatives, academics and policy developers. Analysis of transcribed interviews was undertaken using a process of constant comparison and framework analysis, with coding of emergent themes. Results: Stakeholders generally viewed SP positively and perceived benefits in terms of improved access to medicines and fewer delays, along with a range of facilitators and barriers to the implementation of this form of non-medical prescribing. Stakeholders’ views on the economic impact of SP varied, but safety concerns were not considered significant. Future challenges and implications for policy included SP being potentially superseded by independent nurse and pharmacist prescribing, and the need to improve awareness of SP. Several potential tensions emerged including nurses’ versus pharmacists’ existing skills and training needs, supplementary versus independent prescribing, SP theory versus practice and prescribers versus non-prescribing peers. Conclusion: SP appeared to be broadly welcomed by stakeholders and was perceived to offer patient benefits. Several years after its introduction in the UK, stakeholders still perceived several implementation barriers and challenges and these, together with various tensions identified, might affect the success of supplementary and other forms of non-medical prescribing.

Factors associated with outcomes for looked-after children and young people: a correlates review of the literature.

In 2008, the Department of Health made a referral to the National Institute for Health and Clinical Excellence and the Social Care Institute for Excellence to develop joint public health guidance on improving the physical and emotional health and well-being of children and young people looked after by the local authority/state. To help inform the decision-making process by identifying potential research questions pertinent to the outcomes of looked-after children and young people (LACYP), a correlates review was undertaken. Iterative searches of health and social science databases were undertaken; searches of reference lists and citation searches were conducted and all included studies were critically appraised. The correlates review is a mapping review conducted using systematic and transparent methodology. Interventions and factors that are associated (or correlated) with outcomes for LACYP were identified and presented as conceptual maps. This review maps the breadth (rather than depth) of the evidence and represents an attempt to use the existing evidence base to map associations between potential risk factors, protective factors, interventions and outcomes for LACYP. Ninety-two studies were included: four systematic reviews, five non-systematic reviews, eight randomized controlled trials, 66 cohort studies and nine cross-sectional studies. The conceptual maps provide an overview of the key relationships addressed in the current literature, in particular, placement stability and emotional and behavioural factors in mediating outcomes. From the maps, there appear to be some key factors that are associated with a range of outcomes, in particular, number of placements, behavioural problems and age at first placement. Placement stability seems to be a key mediator of directional associations. The correlates review identified key areas where sufficient evidence to conduct a systematic review might exist. These were: transition support, training and support for carers and access to services.

The Impact of Health Scares on Parents' Information Needs and Preferred Information Sources: A Case Study of the MMR Vaccine Scare.

Health scares are characterized by mass media reporting that generates panic about a particular health issue or intervention, and those involved often require information. This article describes a study that aimed to examine the measles, mumps and rubella (MMR) vaccination scare, its impact on parents of young children, and its effect on their need for information. Seventeen semi-structured interviews were carried out with parents in Sheffield, UK. Analysis of the interview transcripts revealed several categories including the one presented in this article, ‘Information and the MMR vaccine’. The health scare increased parents’ information needs in relation to their decision whether to have their child vaccinated. Parents viewed traditional sources of information critically as they did not consider them to be trustworthy. Parents considered trustworthiness of the information source to be an important factor. Ongoing work in this area is investigating these issues through a large-scale, quantitative study.

Factors relating to the uptake of interventions for smoking cessation among pregnant women: A systematic review and qualitative synthesis

INTRODUCTION The review had the aim of investigating factors enabling or discouraging the uptake of smoking cessation services by pregnant women smokers. METHODS The literature was searched for papers relating to the delivery of services to pregnant or recently pregnant women who smoke. No restrictions were placed on study design. A qualitative synthesis strategy was adopted to analyze the included papers. RESULTS Analysis and synthesis of the 23 included papers suggested 10 aspects of service delivery that may have an influence on the uptake of interventions. These were whether or not the subject of smoking is broached by a health professional, the content of advice and information provided, the manner of communication, having service protocols, follow-up discussion, staff confidence in their skills, the impact of time and resource constraints, staff perceptions of ineffectiveness, differences between professionals, and obstacles to accessing interventions. DISCUSSION The findings suggest variation in practice between services and different professional groups, in particular regarding the recommendation of quitting smoking versus cutting down but also in regard to procedural aspects, such as recording status and repeat advice giving. These differences offer the potential for a pregnant woman to receive contradicting advice. The review suggests a need for greater training in this area and the greater use of protocols, with evidence of a perception of ineffectiveness/pessimism toward intervention among some service providers.

A content analysis of mass media sources in relation to the MMR vaccine scare

In light of the mass media coverage that the MMR (measles, mumps and rubella) vaccine received as a result of questions raised about its safety, a content analysis of mass media articles about the MMR vaccine was undertaken. The analysis examined 227 articles published in five different information sources in a 2 month period. The analysis looked at 94 content-based variables and the key attributes of these articles including word count and date of publication. Descriptive and analytical statistics relating to both article content and format were produced. The analysis showed that the content and format of articles between different information sources varied widely. These differences can be attributed to the information source in which they are published, but the variability in the content of these information sources provides a challenge to parents who were shown to be using the mass media as an information source.

The effectiveness of training and support for carers and other professionals on the physical and emotional health and well-being of looked-after children and young people: a systematic review

Looked-after children and young people (LACYP) are recognized as a high-risk group for behavioural and emotional problems, and additional specialist training for foster carers may reduce such problems. This systematic review aimed to identify and synthesize evidence on the effectiveness of additional training and support provided to approved carers, professionals and volunteers on the physical and emotional health and well-being of LACYP (including problem behaviours and placement stability). Searches of health and social science databases were conducted and records were screened for inclusion criteria. Citation and reference list searches were conducted on included studies. Included studies were synthesized and critically appraised. Six studies were included (five randomized controlled trials and one prospective cohort study), all of which focused on foster carers. Three studies reported a benefit of training and three reported no benefit but no detriment. Those reporting a benefit of training were conducted in the USA, and had longer-duration training, shorter follow-up assessment and recruited carers of younger children than studies that reported no benefit of training, which were conducted in the UK. Whether the difference in results is due to the type of training or to cultural or population differences is unclear. The findings suggest a mixed effect of training for foster carers on problem behaviours of LACYP. The evidence identified appears to suggest that longer-duration training programmes have a beneficial effect on the behaviour problems of LACYP, although future research should examine the impact of training durations and intensity on short-medium and longer-term outcomes of LACYP of different ages. Only training and support for foster carers was identified.

Systematic review and narrative synthesis of the effectiveness of contraceptive service interventions for young people, delivered in educational settings.

STUDY OBJECTIVE This review was undertaken to determine the effectiveness of contraception service interventions for young people that were delivered in educational settings. DESIGN We conducted a systematic review and narrative synthesis. SETTING Interventions were included where they were delivered in educational institutions, including schools, colleges, and pupil referral units. PARTICIPANTS Young people aged 19 and under. Studies of wider age groups were included if the majority of participants were aged under 19 years. INTERVENTIONS We included interventions which consisted of contraceptive service provision, and also interventions to encourage young people to use existing contraceptive services. MAIN OUTCOME MEASURES The main outcome measures used in the studies were: rate of teenage pregnancy, rate of contraceptive use, and sexual behavior. Many outcome measures were self reported. RESULTS Twenty-nine papers were included which reported on interventions to prevent adolescent pregnancy (and repeat pregnancy), school-based health centers, contraceptive use in college students, and multicomponent interventions. Intensive case management intervention conducted by a culturally matched school-based social worker (along with other components including peer education) were shown to be effective in preventing repeat adolescent pregnancy, at least for the duration of the intervention. Also, school-based health centers appear to be most effective when contraception provision is made available on site. CONCLUSIONS The evidence from these papers is limited, in terms of both quality and quantity, along with consistency of findings, but some recommendations in relation to effective interventions can be made.
