Background: Liver disease is an increasing cause of morbidity and mortality in the United Kingdom and can be challenging to live with in the advanced stages. There has been little research exploring the healthcare experiences of UK individuals with decompensated disease when the liver cannot carry out its functions properly. A PhD research project was developed with people who have liver disease to explore care experiences in decompensated advanced liver disease. Public involvement (PI) is an essential aspect of meaningful health research, and this paper reports on the progression of our PI approach in this ongoing study. Objective: To embed PI throughout the research project to ensure that the study is meaningful to individuals with liver disease and the people who support them. Methods: The research adopts a Constructivist Grounded Theory methodology to develop a theory of care experience. Various PI approaches were considered in developing the PI strategy for this qualitative study. Initially, Embedded consultation was the preferred model, which has evolved to include aspects of collaboration and coproduction. A PI group was set up to oversee the project through the national public engagement website VOICE, and reflections on PI from three members of the group are included in this paper to illuminate the PI process. Results: Six individuals with liver disease and three carers from across the United Kingdom are part of an ongoing PI group. Their role includes commenting on the findings of the systematic literature review for this project and contributing to decisions about recruitment, data collection and data analysis. Additionally, they had a direct impact on changing the focus of the research. The PI group will continue involvement until the completion of the project. Conclusion: Successfully embedding PI into doctoral research, as demonstrated in this project, requires commitment, planning and dedication to reciprocal working for the benefit of PI contributors as well as the research. This approach could be adopted by other postgraduate researchers. Patient or Public Contribution: This project is overseen by the PI group, whose contribution is described throughout, including reflections from three PI group members. [ABSTRACT FROM AUTHOR]

Background: Treatment fidelity refers to the degree to which an intervention is implemented as intended. Promoting treatment fidelity is important to achieve a valid comparison in intervention research. However, it is often underreported: few studies detail the use and development of fidelity measures. This study aims to promote the treatment fidelity of a modified version of the Derbyshire Language Scheme (M‐DLS), a manualised intervention for children with language difficulties, by exploring participants' opinions on training and intervention delivery. Results inform development of a checklist and scoring system to monitor and promote treatment fidelity in a comparison trial. Method: Ten student speech and language therapists (SLTs) and two research assistants (RAs) participated in the study. All received training on the M‐DLS, and 10 were video‐recorded completing role‐plays of an M‐DLS session in small groups. Feedback was gathered after training and role‐plays in focus groups and interviews. Feedback was interpreted using the constructs of the Theoretical Domains Framework (TDF). A treatment fidelity checklist was then developed using the feedback. The first author and two RAs rated role‐play videos using the checklist to trial it to inform amendments and to promote interrater reliability. Interrater agreement was calculated using Spearman's test of correlation. Results: Participants discussed the importance of having clear materials and time to practise sessions. They suggested amendments to the materials and training to promote treatment fidelity. The checklist and scoring system accounted for participants' suggestions, with amendments detailed in a log. Spearman's correlation results suggested agreement between the raters was strong. Conclusions: Results emphasise the importance of training quality, practice and reflective opportunities and clear materials to promote treatment fidelity. The construction of the checklist and scoring system was described in detail, informing the development of future checklists. After further trialling, the checklist can be used to ensure the M‐DLS is delivered with high treatment fidelity in the comparison trial. What this paper adds: What is already known on this subject: Treatment fidelity is an essential component of intervention effectiveness and efficacy studies, ensuring the intervention is delivered as intended. It is also an essential component of evidence-based clinical practice. However, few research studies report the treatment fidelity process or publish the checklists used, depriving clinicians of useful information for implementation. What this study adds: This study describes in detail the iterative process of treatment fidelity checklist development, engaging those implementing the intervention in development. This ensured clarity and interrater reliability of the checklist. Furthermore, a novel scoring system was developed so that accuracy of implementation can be easily compared across users and across practice attempts. What are the clinical implications of this work?: The importance of treatment fidelity when implementing effective and efficacious interventions cannot be overstated. The treatment fidelity checklist developed for research can be easily adopted to support accurate implementation in clinical practice through an audit process. [ABSTRACT FROM AUTHOR]

Background: Very young children from lower socioeconomic status (SES) backgrounds often show poorer language development. Whilst there have been attempts to provide early intervention programmes, these sometimes miss the most disadvantaged groups. Aims: This report presents preliminary feasibility and effectiveness data for a novel language intervention designed for parents of toddlers in the United Kingdom. Methods and Procedures: In total, 43 UK families of 2–4‐year‐olds were recruited to the study, half of whom completed an 8‐week course (Tots Talking) focussed on parent interaction, and half of whom acted as wait‐list controls. Results and Outcomes: Results suggest that such programmes are feasible for families with 86% staying in the intervention. In addition, greater changes in underlying communication skills such as joint attention and gesture were evident compared to wait‐list controls. Conclusions and Implications: We conclude that pre‐verbal skills may be more important to measure as initial outcomes than language or vocabulary change in this population. What This Paper Adds: What is already known on the subject: Children from lower socioeconomic status (SES) backgrounds are at higher risk of communication difficulties and there is a need for community intervention programmes for very young children. What this study adds: This study suggests that such programmes can be feasible and effective, but that very early/basic communicative skills (such as joint attention) may be boosted first rather than language or vocabulary. What are the clinical implications of this work?: Children's centres and other community services could feasibly run short parent facing courses emphasising contingent communication in low SES families and other diverse groups. These may be more successful run with younger preschoolers. Joint attention may be a better focus of intervention before expecting vocabulary or language change. Community health professionals may find this information useful in referring and supporting families in need. [ABSTRACT FROM AUTHOR]

Previous research has found that music brings back more vivid and emotional autobiographical memories than various other retrieval cues. However, such studies have often been low in ecological validity and constrained by relatively limited cue selection and predominantly young adult samples. Here, we compared music to food as cues for autobiographical memories in everyday life in young and older adults. In two separate four‐day periods, 39 younger (ages 18–34) and 39 older (ages 60–77) adults recorded their music‐ and food‐evoked autobiographical memories in paper diaries. Across both age groups, music triggered more frequent autobiographical memories, a greater proportion of involuntary memories, and memories rated as more personally important in comparison to food cues. Age differences impacted music‐ and food‐evoked memories similarly, with older adults consistently recalling older and less specific memories, which they rated as more positive, vivid, and rehearsed. However, young and older adults did not differ in the number or involuntary nature of their recorded memories. This work represents an important step in understanding the phenomenology of naturally occurring music‐evoked autobiographical memories across adulthood and provides new insights into how and why music may be a more effective trigger for personally valued memories than certain other everyday cues.

Background: Developmental language disorder (DLD) has clear functional ramifications in the areas of social competency, emotion recognition, emotional well‐being and literacy skill, which have been found to persist from childhood to adolescence. These domains are important factors during the transition from primary to secondary school in typical development (TD). Nevertheless, there is a paucity of research on the transition from primary to secondary school for adolescents with DLD and low language (LL) ability. Aims: To investigate the association between psychosocial domains, literacy skill and concerns about school during the transition to secondary school for adolescents with DLD, LL and their TD peers. The first research question examined whether levels of social competency, emotion recognition, emotional well‐being and literacy skill predicted school concern for the three groups. The second research question explored the longitudinal relationship between school concern and psychosocial and literacy indicators over the transition. Methods & Procedures: Participants (aged 10–11 years) with DLD (n = 30), LL ((n = 29) and TD (n = 42) were recruited for this longitudinal study from eight UK primary schools. Standardized language and psychosocial assessments were administered in the spring and summer terms of the final year of primary school, and the autumn and summer terms of the first year in secondary school. Outcomes & Results: Regression analyses showed pre‐transition school concern to be predicted by emotion recognition for the DLD group, by social competence and emotional well‐being for the LL group, and by social competence for the TD group. Post‐transition concern was predicted by emotional well‐being for the LL group; with no significant predictors for the DLD/TD groups. Path analyses revealed an association between literacy skill and emotion recognition for the DLD group. A developmental cascade illustrated a relationship between social competence and emotional well‐being for the TD group. Conclusions & Implications: This study concludes that transition interventions must be differentiated according to language ability; support for DLD adolescents should focus on emotion recognition skill, provision for LL adolescents should centre on emotional well‐being, and TD participants should be particularly supported in the domain of social competence in advance of the move to secondary school. Additionally, this study emphasizes the importance of the inclusion of a LL group, as their outcomes cannot be predicted using DLD/TD research. WHAT THIS PAPER ADDS: What is already known on the subject: There is limited research exploring the transition from primary school to secondary for adolescents with DLD or LL ability. Research on TD has highlighted vulnerable domains at this time. As these key areas are evidenced spheres of difficulty in DLD and LL, there was a strong impetus for this study. What this paper adds to existing knowledge: This study reveals differences between language ability groups in the predictors of school concern both pre‐ and post‐transition. Concerns of adolescents with DLD were predicted by emotion recognition, those of adolescents with LL were predicted by emotional well‐being, and a longitudinal link between social competence and emotional well‐being was evidenced for TD adolescents. What are the potential or actual clinical implications of this work?: This study has implications for researchers and clinicians, as a need has been identified for a new clinical group. It also has practical implications for transition support planning for educational practitioners, families and adolescents. [ABSTRACT FROM AUTHOR]

Background: Teenagers represent a small proportion of patients on paediatric intensive care units (PICU) in the United Kingdom. During a time when their development is rapidly changing, an admission to PICU causes additional disruption. The impact of critical illness on psychological health after discharge has not been widely reported within this population. Aim and objectives: To measure anxiety that teenagers report 48‐96 hours and 4 weeks after discharge from PICU. To explore teenagers' experiences of being admitted onto PICU. Design: Two‐phase mixed methods, explanatory sequential design. Methods: This single‐site study was conducted between February and July 2018. An NHS Ethics committee approved the study. Teenagers were screened if they were aged 13‐18 years old and had an elective or emergency admission to PICU for longer than 24 hours. Hospital Anxiety and Depression Scale, Anxiety subscale (HADS‐A) was administered on paper and completed with the researcher present. Semi‐structured interviews were conducted in‐person and over the telephone, audio‐recorded and transcribed verbatim. Data were analysed using inductive thematic analysis. Results: Nine of eighteen participants (50%) obtained scores indicating levels of anxiety which were mild (n = 3; 17%), moderate (n = 2; 11%), or severe (n = 4; 22%) 48‐96 hours after PICU discharge. Four weeks later, all participants scored below the clinically significant cut‐off level for the HADS‐A‐1 Teenagers described their experiences on PICU within three themes:Memories of treatments, side effects, and the PICU environmentLosing a sense of selfFeeling cared for Conclusions: Measured levels of anxiety had resolved in this small sample, 4 weeks after PICU discharge. This finding was not consistent with qualitative data that indicated that many experiences shared by participants were anxiety provoking. Relevance to clinical practice: Support for teenagers after PICU discharge should be available to meet individual needs; screening teenagers to identify support needs would be beneficial.

Learning analytics (LA) has demonstrated great potential in improving teaching quality, learning experience and administrative efficiency. However, the adoption of LA in higher education is often beset by challenges in areas such as resources, stakeholder buy‐in, ethics and privacy. Addressing these challenges in a complex system requires agile leadership that is responsive to pressures in the environment and capable of managing conflicts. This paper examines LA adoption processes among 21 UK higher education institutions using complexity leadership theory as a framework. The data were collected from 23 interviews with institutional leaders and subsequently analysed using a thematic coding scheme. The results showed a number of prominent challenges associated with LA deployment, which lie in the inherent tensions between innovation and operation. These challenges require a new form of leadership to create and nurture an adaptive space in which innovations are supported and ultimately transformed into the mainstream operation of an institution. This paper argues that a complexity leadership model enables higher education to shift towards more fluid and dynamic approaches for LA adoption, thus ensuring its scalability and sustainability.

Background: Comparative optimism, the belief that negative events are more likely to happen to others rather than to oneself, is well established in health risk research. It is unknown, however, whether comparative optimism also permeates people's health expectations and potentially behaviour during the COVID‐19 pandemic. Objectives: Data were collected through an international survey (N = 6485) exploring people's thoughts and psychosocial behaviours relating to COVID‐19. This paper reports UK data on comparative optimism. In particular, we examine the belief that negative events surrounding risk and recovery from COVID‐19 are perceived as more likely to happen to others rather than to oneself. Methods: Using online snowball sampling through social media, anonymous UK survey data were collected from N = 645 adults during weeks 5‐8 of the UK COVID‐19 lockdown. The sample was normally distributed in terms of age and reflected the UK ethnic and disability profile. Findings: Respondents demonstrated comparative optimism where they believed that as compared to others of the same age and gender, they were unlikely to experience a range of controllable (eg accidentally infect/ be infected) and uncontrollable (eg need hospitalization/ intensive care treatment if infected) COVID‐19‐related risks in the short term (P <.001). They were comparatively pessimistic (ie thinking they were more at risk than others for developing COVID‐19‐related infection or symptoms) when thinking about the next year. Discussion: This is one of the first ever studies to report compelling comparative biases in UK adults' thinking about COVID‐19. [ABSTRACT FROM AUTHOR]

Background & objectives: The comparative uses of different types of patient experience (PE) feedback as data within quality improvement (QI) are poorly understood. This paper reviews what types are currently available and categorizes them by their characteristics in order to better understand their roles in QI. Methods: A scoping review of types of feedback currently available to hospital staff in the UK was undertaken. This comprised academic database searches for "measures of PE outcomes" (2000‐2016), and grey literature and websites for all types of "PE feedback" potentially available (2005‐2016). Through an iterative consensus process, we developed a list of characteristics and used this to present categories of similar types. Main results: The scoping review returned 37 feedback types. A list of 12 characteristics was developed and applied, enabling identification of 4 categories that help understand potential use within QI—(1) Hospital‐initiated (validated) quantitative surveys: for example the NHS Adult Inpatient Survey; (2) Patient‐initiated qualitative feedback: for example complaints or twitter comments; (3) Hospital‐initiated qualitative feedback: for example Experience Based Co‐Design; (4) Other: for example Friends & Family Test. Of those routinely collected, few elicit "ready‐to‐use" data and those that do elicit data most suitable for measuring accountability, not for informing ward‐based improvement. Guidance does exist for linking collection of feedback to QI for some feedback types in Category 3 but these types  are not routinely used. Conclusion: If feedback is to be used more frequently within QI, more attention must be paid to obtaining and making available the most appropriate types. [ABSTRACT FROM AUTHOR]

When appraising research papers, how much understanding is enough? More specifically, in deciding whether research results can inform practice, do appraisers need to substantively understand how findings are derived or is it sufficient simply to grasp that suitable analytic techniques were chosen and used by researchers? The degree or depth of understanding that research appraisers need to attain before findings can legitimately/sensibly inform practice is underexplored. In this paper it is argued that, where knowledge/justified beliefs derived from research evidence prompt actions that materially affect patient care, appraisers have an epistemic duty to demand high (maximal) rather than low (minimal) levels of understanding regards finding derivation (i.e. appraisers have a duty to seek a superior epistemic situation). If this argument holds assumptions about appraiser competence/ability and the feasibility of current UK conceptions of evidence based practice are destabilized. [ABSTRACT FROM AUTHOR]

Little research so far has been devoted to understanding the diffusion of grassroots innovation for sustainability across space. This paper explores and compares the spatial diffusion of two networks of grassroots innovations, the Transition Towns Network ( TTN) and Gruppi di Acquisto Solidale ( Solidarity Purchasing Groups - GAS), in Great Britain and Italy. Spatio-temporal diffusion data were mined from available datasets, and patterns of diffusion were uncovered through an exploratory data analysis. The analysis shows that GAS and TTN diffusion in Italy and Great Britain is spatially structured, and that the spatial structure has changed over time. TTN has diffused differently in Great Britain and Italy, while GAS and TTN have diffused similarly in central Italy. The uneven diffusion of these grassroots networks on the one hand challenges current narratives on the momentum of grassroots innovations, but on the other highlights important issues in the geography of grassroots innovations for sustainability, such as cross-movement transfers and collaborations, institutional thickness, and interplay of different proximities in grassroots innovation diffusion.

Aims and objectives: The aim of this paper is to determine the influence of do not attempt cardiopulmonary resuscitation (DNACPR) orders and the Universal Form of Treatment Options (‘UFTO’: an alternative approach that contextualizes the resuscitation decision within an overall treatment plan) on nurses' decision making about a deteriorating patient. Methods: An online survey with a developing case scenario across three timeframes was used on 231 nurses from 10 National Health Service Trusts. Nurses were randomised into three groups: DNACPR, the UFTO and no‐form. Statements were pooled into four subcategories: Increasing Monitoring, Escalating Concern, Initiating Treatments and Comfort Measures. Results: Reported decisions were different across the three groups. Nurses in the DNACPR group agreed or strongly agreed to initiate fewer intense nursing interventions than the UFTO and no‐form groups (P < 0.001) overall and across subcategories of Increase Monitoring, Escalate Concern and Initiate Treatments (all P < 0.001). There was no difference between the UFTO and no‐form groups overall (P = 0.795) or in the subcategories. No difference in Comfort Measures were observed (P = 0.201) between the three groups. Conclusion: The presence of a DNACPR order appears to influence nurse decision making in a deteriorating patient vignette. Differences were not observed in the UFTO and no‐form group. The UFTO may improve the way nurses modulate their behaviours towards critically ill patients with DNACPR status. More hospitals should consider adopting an approach where the resuscitation decisions are contextualised within overall goals of care. [ABSTRACT FROM AUTHOR]

Background: Public involvement in research (PIR) can improve research design and recruitment. Less is known about how PIR enhances the experience of participation and enriches the data collection process. In a study to evaluate how UK care homes and primary health‐care services achieve integrated working to promote older people's health, PIR was integrated throughout the research processes. Objectives: This paper aims to present one way in which PIR has been integrated into the design and delivery of a multisite research study based in care homes. Design: A prospective case study design, with an embedded qualitative evaluation of PIR activity. Setting and participants: Data collection was undertaken in six care homes in three sites in England. Six PIR members participated: all had prior personal or work experience in care homes. Data collection: Qualitative data collection involved discussion groups, and site‐specific meetings to review experiences of participation, benefits and challenges, and completion of structured fieldwork notes after each care home visit. Results: PIR members supported recruitment, resident and staff interviews and participated in data interpretation. Benefits of PIR work were resident engagement that minimized distress and made best use of limited research resources. Challenges concerned communication and scheduling. Researcher support for PIR involvement was resource intensive. Discussion and conclusions: Clearly defined roles with identified training and support facilitated involvement in different aspects of the data collection process. This can also ensure that vulnerable older people who participate in research have a positive experience that reinforces the value of their views. [ABSTRACT FROM AUTHOR]

Background: Despite the availability of effective evidence‐based treatments for depression and anxiety, many ‘harder‐to‐reach’ social and patient groups experience difficulties accessing treatment. We developed a complex intervention, the AMP (Improving Access to Mental Health in Primary Care) programme, which combined community engagement (CE), tailored (individual and group) psychosocial interventions and primary care involvement. Objectives: To develop and evaluate a model for community engagement component of the complex intervention. This paper focuses on the development of relationships between stakeholders, their engagement with the issue of access to mental health and with the programme through the CE model. Design: Our evaluation draws on process data, qualitative interviews and focus groups, brought together through framework analysis to evaluate the issues and challenges encountered. Setting & participants: A case study of the South Asian community project carried out in Longsight in Greater Manchester, United Kingdom. Key findings: Complex problems require multiple local stakeholders to work in concert. Assets based approaches implicitly make demands on scarce time and resources. Community development approaches have many benefits, but perceptions of open‐ended investment are a barrier. The time‐limited nature of a CE intervention provides an impetus to ‘do it now’, allowing stakeholders to negotiate their investment over time and accommodating their wider commitments. Both tangible outcomes and recognition of process benefits were vital in maintaining involvement. Conclusions: CE interventions can play a key role in improving accessibility and acceptability by engaging patients, the public and practitioners in research and in the local service ecology.

Current policy in UK health services emphasizes that, where possible, people with intellectual disabilities should access the same services as people without intellectual disabilities. One of the barriers to this is the confidence of clinicians and therapists. In this paper, we report on the development of a scale to describe the confidence of therapists in working with people with intellectual disabilities (the Therapy Confidence Scale-Intellectual Disabilities [TCS-ID]). One-hundred and eighty-one therapists who provided talking therapies but who did not work primarily with people with intellectual disabilities completed the scale; 43 people completed the scale twice for test-retest reliability purposes. One-hundred and seven people also completed a scale of general therapy self-efficacy. The TCS-ID has a single factor structure accounting for 62% of the variance, Cronbach's alpha for the scale is 0.93 and test-retest reliability is 0.83. There are significant differences in confidence based upon participants experience in working with people with intellectual disabilities and their therapeutic orientation, and there is a significant association between the TCS-ID and the General Therapy Self-efficacy Scale. Sixty clinicians working in mainstream mental health services received training on adapting their therapeutic approaches to meet the needs of people with intellectual disabilities. The TCS-ID was used pre-training and post-training and demonstrated a significant increase in confidence for all group. We suggest that the scale has good psychometric properties and can be used to develop an understanding of the impact of training for mainstream therapist in working with people with intellectual disabilities. Copyright © 2014 John Wiley & Sons, Ltd. Key Practitioner Message There is increasing emphasis on people with intellectual disabilities receiving services from mainstream mental health services., There is no research describing the experiences and outcomes of people with intellectual disabilities receiving mainstream talking therapy services., The confidence that clinicians have in working with people with intellectual disabilities may be a barrier to them receiving mainstream services., The Therapy Confidence Scale-Intellectual Disabilities is a psychometrically sound scale for measuring the confidence of therapists in working with people with intellectual disabilities and is a useful outcome measure for training clinicians to work with people with intellectual disabilities.

Aims To investigate the extent of and factors associated with adherence to Type 2 diabetes medication. Methods The CINAHL, Embase, International Pharmaceutical Abstracts, Medline, PubMed and Psych INFO databases were searched for the period January 2004 to July 2013. Papers were included in the present review if they reported the prevalence of adherence (the percentage of the study population that is classified as adherent) to Type 2 diabetes medication and used validated adherence measures with a defined cut-off point to indicate adherence. Reported factors were classified as potential predictors if the studies that examined that particular variable reported consistent findings. Results Of the 27 studies included in the present review, the prevalence of adherence ranged from 38.5 to 93.1%. Only six out of 27 studies (22.2%) reported prevalence of adherence of ≥ 80% among their study population. Depression and medication cost were found to be consistent and potentially modifiable predictors for diabetes medication-taking behaviour. The associations between adherence and other factors were inconsistent among the reviewed studies. Conclusions Adherence to diabetes medication remains an ongoing problem. This review has highlighted the urgent need to develop consensus about what constitutes good adherence in diabetes. Further research is needed to clarify modifiable factors, in addition to depression and medication cost, that influence adherence and may provide a focus for targeted interventions to promote adherence, optimize diabetes control and limit the progression of diabetes.

Background Mindfulness-based interventions have been shown to be effective in the treatment of a range of health and psychological disorders in adults and young people without intellectual disabilities ( ID). Clinical studies are emerging reporting on the efficacy of mindfulness-based interventions as a stand-alone treatment for common clinical disorders in adults with ID. Method This paper aims to evaluate the efficacy of an innovative structured mindfulness-based cognitive therapy ( MBCT) group programme adapted for adults with ID with a diagnosis of either recurrent depression, anxiety or both clinical conditions and a history of deliberate self-harm behaviour. Two groups ran consecutively consisting of a total of fifteen participants and seven carers. All participants were recorded as having either a borderline, mild, or moderate ID. The group programme ran over a period of 9 weeks with a follow-up session at 6 weeks post group intervention. Outcome measures included the Hospital Anxiety and Depression Scale and two sub-scales from the Self- Compassion Scale administered at baseline, post therapy and at 6-week follow-up. Results The evaluation showed that participants reported an improvement in their experience of depression, anxiety, self-compassion and compassion for others. The most significant impact was in the reduced levels of anxiety reported. Improvements across all outcomes were maintained at 6-week follow-up. Conclusion The results of the evaluation suggest that people with intellectual disabilities benefit from a structured MBCT group intervention and the results are maintained at 6-week follow-up.

Background Statements or commitments making use of numbers have an important place in government policy. They appear at all stages of the policy process: campaigning, formulation, monitoring and evaluation. Many types of source are involved including research studies, national survey information, routine operational data collections and special systems devised to monitor particular initiatives. Method The paper presents examples of policy uses of numerical evidence, and some sources of data that have been used to support them in the field of care for people with intellectual developmental disability in England. Conclusions Different levels of precision or coverage are required at different stages of the process. Different types of numerical data are appropriate at the various stages of the policy process.

Rationale, aims and objectives Differences in the performance of medical care may be due to variation in the introduction and diffusion of medical innovations. The objective of this paper is to compare seven European countries ( United Kingdom, the Netherlands, West Germany, France, Spain, Estonia and Sweden) with regard to the year of introduction of six specific pharmaceutical innovations (antiretroviral drugs, cimetidine, tamoxifen, cisplatin, oxalaplatin and cyclosporin) that may have had important population health impacts. Methods We collected information on introduction and further diffusion of drugs using searches in the national and international literature, and questionnaires to national informants. We combined various sources of information, both official years of registration and other indicators of introduction (clinical trials, guidelines, evaluation reports, sales statistics). Results and conclusions The total length of the period between first and last introduction varied between 8 years for antiretroviral drugs and 22 years for cisplatin. Introduction in Estonia was generally delayed until the 1990s. The average time lags were smallest in France (2.2 years), United Kingdom (2.8 years) and the Netherlands (3.5 years). Similar rank orders were seen for year of registration suggesting that introduction lags are not only explained by differences in the process of registration. We discuss possible reasons for these between-country differences and implications for the evaluation of medical care. [ABSTRACT FROM AUTHOR]
