    EVIDENCE SYNTHESIS: Appropriateness of using a symbol to identify dementia and/or delirium

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 3 2010
    Sonia Hines RN BN
    Abstract Aim, The main objective of this systematic review was to evaluate any published and unpublished evidence regarding the appropriateness of developing a symbol for dementia and/or delirium, which could be used in a variety of settings to indicate that a person has dementia and/or delirium. Methods, Using the methods of the Joanna Briggs Institute, we conducted a systematic search of a wide range of databases, Internet resources and unpublished literature. Papers meeting the inclusion criteria were critically appraised by two independent reviewers. Data were extracted, using the standardised tool from the Joanna Briggs Institute, from those papers considered to be of sufficient quality. Because of significant methodological heterogeneity, no meta-analysis was possible and results are presented narratively instead. Results, From a total of 37 retrieved papers, 18 were found to be of sufficient relevance and quality to be included in the review. There was general consensus among the literature that a symbol for dementia is appropriate in the acute care setting. It was also clear from the research that an abstract symbol, as opposed to one that explicitly attempts to depict dementia, was most acceptable to staff, people with dementia and their carers. Conclusions, Both staff and health consumers seem to have largely positive perceptions and attitudes towards the use of a symbol for dementia. Families and carers of people with dementia are frequently concerned about their loved one wandering away and becoming lost and unable to identify themselves, and these concerns seem to outweigh any reservations they hold about the use of a symbol or some other identifier. In healthcare settings the use of symbols to indicate special needs seems well established and widely accepted. However, regarding the use of a symbol for dementia in the broader community, there remain concerns about issues such as stigmatisation and the potential for victimisation of this vulnerable population and so further research is indicated.

    The effectiveness of Cognitive,Behavioural Therapy with hopeful elements to prevent the development of depression in young people: a systematic review

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 1 2009
    Anthony Venning B Hth Sci (Hons), B Soc
    Abstract Background, The onset of depression during adolescence can adversely impact future functioning. Cognitive,Behavioural Therapy (CBT) has been suggested to prevent depression in adolescence by providing an individual with the ability to interpret and the tools to deal with the impact of negative life events. Objective, Examine the best available evidence to determine the effectiveness of CBT to prevent the onset of depression in young people, and assess whether the incorporation of hopeful elements makes CBT more effective. Search strategy, A comprehensive three-step search strategy was developed to find both published and unpublished studies in English from 1987 to March 2007. Papers selected for retrieval were then assessed for methodological validity by two independent reviewers. Selection criteria, Papers that used a randomised controlled design and investigated the efficacy of CBT to prevent the onset of depression in young people between the age of 10 years and 16 years were included. Papers were included if the CBT involved between four and 15 sessions, a follow-up period of between 3 and 24 months and included typical strategies, such as the identification of negative and irrational beliefs, the establishment of links between thoughts, feelings and behaviours, and provided tools so participants could self-monitor these. Data analysis, Data were extracted using the standard tool from the Joanna Briggs Institute, pooled in a meta-analysis, and then grouped and analysed according to the amount of hopeful elements the CBT was judged to contain. Results and conclusion, Limited evidence was found to indicate that CBT, regardless of its content (i.e. with or without hopeful elements), is effective at preventing the onset of clinical levels of depression in young people on a sustained basis. Nonetheless, given the devastating impact that depression can have on young people's future functioning, further research is needed to develop effective interventions to equip young people with the cognitive skills to buffer its onset on a more sustained basis and to enable them to reach and sustain mental health.

    Effectiveness of simulation on health profession students' knowledge, skills, confidence and satisfaction

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 3 2008
    Susan Laschinger
    Abstract Background, Despite the recent wave of interest being shown in high-fidelity simulators, they do not represent a new concept in healthcare education. Simulators have been a part of clinical education since the 1950s. The growth of patient simulation as a core educational tool has been driven by a number of factors. Declining inpatient populations, concerns for patient safety and advances in learning theory are forcing healthcare educators to look for alternatives to the traditional clinical encounter for skill acquisition for students. Objective, The aim of this review was to identify the best available evidence on the effectiveness of using simulated learning experiences in pre-licensure health profession education. Inclusion criteria,Types of studies: This review considered any experimental or quasi-experimental studies that addressed the effectiveness of using simulated learning experiences in pre-licensure health profession practice. In the absence of randomised controlled trials, other research designs were considered for inclusion, such as, but not limited to: non-randomised controlled trials and before-and-after studies. Types of participants: This review included participants who were pre-licensure practitioners in nursing, medicine, and rehabilitation therapy. Types of intervention(s)/phenomena of interest: Studies that evaluated the use of human physical anatomical models with or without computer support, including whole-body or part-body simulators were included. Types of outcome measures, Student outcomes included knowledge acquisition, skill performance, learner satisfaction, critical thinking, self-confidence and role identity. Search strategy, Using a defined search and retrieval method, the following databases were accessed for the period 1995,2006: Medline, CINAHL, Embase, PsycINFO, HealthSTAR, Cochrane Database of Systematic Reviews and ERIC. Methodological quality, Each paper was assessed by two independent reviewers for methodological quality prior to inclusion in the review using the standardised critical appraisal instruments for evidence of effectiveness, developed by the Joanna Briggs Institute. Disagreements were dealt with by consultations with a third reviewer. Data collection, Information was extracted from each paper independently by two reviewers using the standardised data extraction tool from the Joanna Briggs Institute. Disagreements were dealt with by consultation with a third reviewer. Data synthesis, Due to the type of designs and quality of available studies, it was not possible to pool quantitative research study results in statistical meta-analysis. As statistical pooling was not possible, the findings are presented in descriptive narrative form. Results, Twenty-three studies were selected for inclusion in this review including partial task trainers and high-fidelity human patient simulators. The results indicate that there is high learner satisfaction with using simulators to learn clinical skills. The studies demonstrated that human patient simulators which are used for teaching higher level skills, such as airway management, and physiological concepts are useful. While there are short-term gains in knowledge and skill performance, it is evident that performance of skills over time after initial training decline. Conclusion, At best, simulation can be used as an adjunct for clinical practice, not a replacement for everyday practice. Students enjoyed the sessions and using the models purportedly makes learning easier. However, it remains unclear whether the skills learned through a simulation experience transfer into real-world settings. More research is needed to evaluate whether the skills acquired with this teaching methodology transfer to the practice setting such as the impact of simulation training on team function. [source]


    Effectiveness of interventions that assist caregivers to support people with dementia living in the community: a systematic review

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 2 2008
    Deborah Parker BA, MSocSci
    Executive summary Objectives, The objective of this review was to assess the effectiveness of interventions that assist caregivers to provide support for people living with dementia in the community. Inclusion criteria, Types of participants, Adult caregivers who provide support for people with dementia living in the community (non-institutional care). Types of interventions, Interventions designed to support caregivers in their role such as skills training, education to assist in caring for a person living with dementia and support groups/programs. Interventions of formal approaches to care designed to support caregivers in their role, care planning, case management and specially designated members of the healthcare team , for example dementia nurse specialist or volunteers trained in caring for someone with dementia. Types of studies, This review considered any meta-analyses, systematic reviews, randomised control trials, quasi-experimental studies, cohort studies, case control studies and observational studies without control groups that addressed the effectiveness of interventions that assist caregivers to provide support for people living with dementia in the community. Search strategy, The search sought to identify published studies from 2000 to 2005 through the use of electronic databases. Only studies in English were considered for inclusion. The initial search was conducted of the databases, CINAHL, MEDLINE and PsychINFO using search strategies adapted from the Cochrane Dementia and Cognitive Improvement Group. A second more extensive search was then conducted using the appropriate Medical Subject Headings (MeSH) and keywords for other available databases. Finally, hand searching of reference lists of articles retrieved and of core dementia, geriatric and psycho geriatric journals was undertaken. Assessment of quality, Methodological quality of each of the articles was assessed by two independent reviewers using appraisal checklist developed by the Joanna Briggs Institute and based on the work of the Cochrane Collaboration and Centre for Reviews and Dissemination. Data collection and analysis, Standardised mean differences or weighted mean differences and their 95% confidence intervals were calculated for each included study reported in the meta-analysis. Results from comparable groups of studies were pooled in statistical meta-analysis using Review Manager Software from the Cochrane Collaboration. Heterogeneity between combined studies was tested using standard chi-square test. Where statistical pooling was not appropriate or possible, the findings are summarised in narrative form. Results, A comprehensive search of relevant databases, hand searching and cross referencing found 685 articles that were assessed for relevance to the review. Eighty-five papers appeared to meet the inclusion criteria based on title and abstract, and the full paper was retrieved. Of the 85 full papers reviewed, 40 were accepted for inclusion, three were systematic reviews, three were meta-analysis, and the remaining 34 were randomised controlled trials. For the randomised controlled trials that were able to be included in a meta-analysis, standardised mean differences or weighted mean differences and their 95% confidence intervals were calculated for each. Results from comparable groups of studies were pooled in statistical meta-analysis using Review Manager Software and heterogeneity between combined studies was assessed by using the chi-square test. Where statistical pooling was not appropriate or possible, the findings are summarised in narrative form. The results are discussed in two main sections. Firstly it was possible to assess the effectiveness of different types of caregiver interventions on the outcome categories of depression, health, subjective well-being, self-efficacy and burden. Secondly, results are reported by main outcome category. For each of these sections, meta-analysis was conducted where it was possible; otherwise, a narrative summary describes the findings. Effectiveness of intervention type, Four categories of intervention were included in the review , psycho-educational, support, multi-component and other. Psycho-educational Thirteen studies used psycho-educational interventions, and all but one showed positive results across a range of outcomes. Eight studies were entered in a meta-analysis. No significant impact of psycho-educational interventions was found for the outcome categories of subjective well-being, self-efficacy or health. However, small but significant results were found for the categories of depression and burden. Support Seven studies discussed support only interventions and two of these showed significant results. These two studies were suitable for meta-analysis and demonstrated a small but significant improvement on caregiver burden. Multi-component Twelve of the studies report multi-component interventions and 10 of these report significant outcomes across a broad range of outcome measures including self-efficacy, depression, subjective well-being and burden. Unfortunately because of the heterogeneity of study designs and outcome measures, no meta-analysis was possible. Other interventions Other interventions included the use of exercise or nutrition which resulted in improvements in psychological distress and health benefits. Case management and a computer aided support intervention provided mixed results. One cognitive behavioural therapy study reported a reduction in anxiety and positive impacts on patient behaviour. Effectiveness of interventions using specific outcome categories, In addition to analysis by type of intervention it was possible to analyse results based on some outcome categories that were used across the studies. In particular the impact of interventions on caregiver depression was available for meta-analysis from eight studies. This indicated that multi-component and psycho-educational interventions showed a small but significant positive effect on caregiver depression. Five studies using the outcome category of caregiver burden were entered into a meta-analysis and findings indicated that there were no significant effects of any of interventions. No meta-analysis was possible for the outcome categories of health, self-efficacy or subjective well-being. Implications for practice, From this review there is evidence to support the use of well-designed psycho-educational or multi-component interventions for caregivers of people with dementia who live in the community. Factors that appear to positively contribute to effective interventions are those which: ,,Provide opportunities within the intervention for the person with dementia as well as the caregiver to be involved ,,Encourage active participation in educational interventions for caregivers ,,Offer individualised programs rather than group sessions ,,Provide information on an ongoing basis, with specific information about services and coaching regarding their new role ,,Target the care recipient particularly by reduction in behaviours Factors which do not appear to have benefit in interventions are those which: ,,Simply refer caregivers to support groups ,,Only provide self help materials ,,Only offer peer support [source]


    The psychosocial spiritual experience of elderly individuals recovering from stroke: a systematic review

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 2 2008
    Marianne Lamb RN
    Abstract Objectives, The objective of this review was to appraise and synthesise best available evidence on the psychosocial spiritual experience of elderly individuals recovering from stroke. Inclusion criteria, This review considered qualitative studies whose participants were adults, mean age of 65 years and older, and who had experienced a minimum of one stroke. Studies were included that described the participant's own experience of recovering from stroke. Search strategy, The search strategy sought to find both published and unpublished studies and papers, not limited to the English language. An initial limited search of MEDLINE and CINAHL was undertaken followed by an analysis of text words contained in the title and abstract, and of index terms used to describe the article. A second extensive search was then undertaken using all identified key words and index terms. Methodological quality, Each paper was assessed by two independent reviewers for methodological quality prior to inclusion in the review using the Qualitative Assessment and Review Instrument (QARI) developed by the Joanna Briggs Institute. Disagreements were resolved through consultation with a third reviewer. Data collection, Information was extracted from each paper independently by two reviewers using the data extraction tool from QARI developed by the Joanna Briggs Institute. Disagreements were resolved through consultation with a third reviewer. Data synthesis, Data synthesis aimed to portray an accurate interpretation and synthesis of concepts arising from the selected population's experience during their recovery from stroke. Results, A total of 35 studies were identified and of those 27 studies were included in the review. These qualitative studies examined the perceptions of elderly individuals who had experienced a stroke. Findings were analysed using JBI-QARI. The process of meta-synthesis using this program involved categorising findings and developing synthesised topics from the categories. Four syntheses were developed related to the perceptions and experiences of stroke survivors: sudden unexpected event, connectedness, reconstruction of life and life-altering event. Conclusion, The onset and early period following a stroke is a confusing and terrifying experience. The period of recovery involves considerable psychological and physical work for elderly individuals to reconstruct their lives. For those with a spiritual tradition, connectedness to others and spiritual connection is important during recovery. The experience of stroke is a life-altering one for most elderly individuals, involving profound changes in functioning and sense of self. [source]


    Effects of music listening on adult patients' pre-procedural state anxiety in hospital

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 1 2008
    Elizabeth Gillen MSc
    Executive summary Background Anticipation of an invasive procedure in hospital is likely to provoke feelings of anxiety and stress in patients. An unfamiliar environment, loss of control, perceived or actual physical risk, dependence on strangers and separation from friends and family are all factors that can contribute to the development of such feelings. Recently, there has been considerable interest in the anxiolytic potential of music listening in a variety of clinical settings, yet thus far, little is known about the impact of music listening on the pre-procedural patient population. A systematic review of all literature to date was indicated to improve understanding of outcomes and impact of music listening on pre-procedural anxiety, thus helping nurses decide whether or not to incorporate music listening into practice and to highlight a need, or otherwise, for a related primary research agenda. Objective The objective of this review was to determine the best available evidence on the effectiveness of music listening in reducing adult hospital patients' pre-procedural state anxiety. Inclusion criteria Types of studies This review included randomised controlled trials and quasi-experimental research designs that examined the efficacy of music listening in reducing state anxiety among pre-procedural hospital patients published between January 1985 and February 2006. The search was limited to publications after 1985 to coincide with the increasing interest and use of complementary therapies within health care during the 1980s and 1990s. Types of participants Participants of interest to the review were adult day patients, ambulatory patients and inpatients who were about to undergo any type of clinical procedure. Types of intervention The review focused on studies that investigated pre-procedural music listening employed and prescribed as a potentially therapeutic activity. It excluded any other form of music therapy. Types of outcome measures The primary outcome measures examined were alterations in state anxiety and a variety of physiological variables such as blood pressure and respiration and heart rates. Search strategy A search for published and unpublished literature between January 1985 and February 2006 was conducted using all major electronic databases. A three-step search strategy was devised which consisted of using high-precision MeSH terminology and keywords to ensure that all material relevant to the review was captured. Critical appraisal The methodological quality of included studies was assessed by two reviewers, who appraised each study independently, using the standard Joanna Briggs Institute (JBI) critical appraisal tools. Data extraction and synthesis Data were extracted from the studies that were identified as meeting the criteria for methodological quality using a data-extraction tool developed for the review. Studies were grouped by outcome measure and summarised using tabular and narrative formats. Results The review demonstrated that state anxiety is defined and measured using both psychological and physiological parameters. Music listening had a consistently positive and statistically significant effect on reducing psychological parameters of pre-procedural state anxiety. However, the results from the measurement of various pre-procedural physiological parameters failed to reveal any consistent positive changes in patients who had listened to music. This calls into question the adequacy of the theories in this area which link anxiety and the automated and central nervous systems and the effect that music listening may have on these processes and physiological responses. Conclusions/implications for practice 1,In order to reduce anxiety, it is likely that patients will benefit psychologically from having the opportunity to listen to music in the immediate pre-procedural period. 2,Patients do not appear to experience any alteration in physiological status as a result of listening to music. 3,Further research is indicated in order to replicate existing studies, to strengthen the evidence to support such interventions and to establish intervention parameters. 4,Further research is needed analysing the physiological mechanisms by which music listening is believed to reduce state anxiety and the contribution of the automated and other nervous systems to this reduction.

    Systematic review on embracing cultural diversity for developing and sustaining a healthy work environment in healthcare

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 1 2007
    Alan Pearson RN, FRCN, FRCNA
    Abstract Objectives, The objective of this review was to evaluate evidence on the structures and processes that support development of effective culturally competent practices and a healthy work environment. Culturally competent practices are a congruent set of workforce behaviours, management practices and institutional policies within a practice setting resulting in an organisational environment that is inclusive of cultural and other forms of diversity. Inclusion criteria, This review included quantitative and qualitative evidence, with a particular emphasis on identifying systematic reviews and randomised controlled trials. For quantitative evidence, other controlled, and descriptive designs were also included. For qualitative evidence, all methodologies were considered. Participants were staff, patients, and systems or policies that were involved or affected by concepts of cultural competence in the nursing workforce in a healthcare environment. Types of interventions included any strategy that had a cultural competence component, which influenced the work environment, and/or patient and nursing staff in the environment. The types of outcomes of interest to this review included nursing staff outcomes, patient outcomes, organisational outcomes and systems level outcomes. Search strategy, The search sought both published and unpublished literature written in the English language. A comprehensive three-step search strategy was used, first to identify appropriate key words, second to combine all optimal key words into a comprehensive search strategy for each database and finally to review the reference lists of all included reviews and research reports. The databases searched were CINAHL, Medline, Current Contents, the Database of Abstracts of Reviews of Effectiveness, The Cochrane Library, PsycINFO, Embase, Sociological Abstracts, Econ lit, ABI/Inform, ERIC and PubMed. The search for unpublished literature used Dissertation Abstracts International. Methodological quality, Methodological quality was independently established by two reviewers, using standardised techniques from the Joanna Briggs Institute (JBI) System for the Unified Management, Assessment and Review of Information (SUMARI) package. Discussion with a third reviewer was initiated where a low level of agreement was identified for a particular paper. Following inclusion, data extraction was conducted using standardised data extraction tools from the JBI SUMARI suite for quantitative and qualitative research. Data synthesis was performed using the JBI Qualitative Assessment and Review Instrument and JBI Narrative, Opinion and Text Assessment and Review Instrument software to aggregate findings by identifying commonalities across texts. Quantitative data were presented in narrative summary, as statistical pooling was not appropriate with the included studies. Results, Of the 659 identified papers, 45 were selected for full paper retrieval, and 19 were considered to meet the inclusion criteria for this review. The results identified a number of processes that would contribute to the development of a culturally competent workforce. Appropriate and competent linguistic services, and intercultural staff training and education, were identified as key findings in this review. Conclusions, The review recommends that health provider agencies establish links with organisations that can address needs of culturally diverse groups of patients, include cultural competence in decision support systems and staff education as well as embed them in patient brochures and educational materials. The review also concluded that staff in-service programs consider the skills needed to foster a culturally competent workforce, and recruitment strategies that also explicitly address this need.

    Factors associated with constructive staff,family relationships in the care of older adults in the institutional setting

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2006
    Emily Haesler BN PGradDipAdvNsg
    Abstract Background, Modern healthcare philosophy espouses the virtues of holistic care and acknowledges that family involvement is appropriate and something to be encouraged due to the role it plays in physical and emotional healing. In the aged care sector, the involvement of families is a strong guarantee of a resident's well-being. The important role family plays in the support and care of the older adult in the residential aged care environment has been enshrined in the Australian Commonwealth Charter of Residents' Rights and Responsibilities and the Aged Care Standards of Practice. Despite wide acknowledgement of the importance of family involvement in the healthcare of the older adult, many barriers to the implementation of participatory family care have been identified in past research. For older adults in the healthcare environment to benefit from the involvement of their family members, healthcare professionals need an understanding of the issues surrounding family presence in the healthcare environment and the strategies to best support it. Objectives, The objectives of the systematic review were to present the best available evidence on the strategies, practices and organisational characteristics that promote constructive staff,family relationships in the care of older adults in the healthcare setting. Specifically this review sought to investigate how staff and family members perceive their relationships with each other; staff characteristics that promote constructive relationships with the family; and interventions that support staff,family relationships. Search strategy, A literature search was performed using the following databases for the years 1990,2005: Ageline, APAIS Health, Australian Family and Society Abstracts (FAMILY), CINAHL, Cochrane Library, Dare, Dissertation Abstracts, Embase, MEDLINE, PsycINFO and Social Science Index. Personal communication from expert panel members was also used to identify studies for inclusion. A second search stage was conducted through review of reference lists of studies retrieved during the first search stage. The search was limited to published and unpublished material in English language. Selection criteria, The review was limited to studies involving residents and patients within acute, subacute, rehabilitation and residential settings, aged over 65 years, their family and healthcare staff. Papers addressing family members and healthcare staff perceptions of their relationships with each other were considered for this review. Studies in this review also included those relating to interventions to promote constructive staff,family relationships including organisational strategies, staff,family meetings, case conferencing, environmental approaches, etc. The review considered both quantitative and qualitative research and opinion papers for inclusion. Data collection and analysis, All retrieved papers were critically appraised for eligibility for inclusion and methodological quality independently by two reviewers, and the same reviewers collected details of eligible research. Appraisal forms and data extraction forms designed by the Joanna Briggs Institute as part of the QARI and NOTARI systematic review software packages were used for this review. Findings, Family members' perceptions of their relationships with staff showed that a strong focus was placed on opportunities for the family to be involved in the patient's care. Staff members also expressed a theoretical support for the collaborative process, however, this belief often did not translate to the staff members' clinical practice. In the studies included in the review staff were frequently found to rely on traditional medical models of care in their clinical practice and maintaining control over the environment, rather than fully collaborating with families. Four factors were found to be essential to interventions designed to support a collaborative partnership between family members and healthcare staff: communication, information, education and administrative support. Based on the evidence analysed in this systematic review, staff and family education on relationship development, power and control issues, communication skills and negotiating techniques is essential to promoting constructive staff,family relationships. Managerial support, such as addressing workloads and staffing issues; introducing care models focused on collaboration with families; and providing practical support for staff education, is essential to gaining sustained benefits from interventions designed to promote constructive family,staff relationships.

    Association between pacifier use and breast-feeding, sudden infant death syndrome, infection and dental malocclusion

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 6 2005
    Ann Callaghan RN RM BNurs(Hons)
    Executive summary Objective, To critically review all literature related to pacifier use for full-term healthy infants and young children. The specific review questions addressed are: What is the evidence of adverse and/or positive outcomes of pacifier use in infancy and childhood in relation to each of the following subtopics: ,breast-feeding; ,sudden infant death syndrome; ,infection; ,dental malocclusion. Inclusion criteria, Specific criteria were used to determine which studies would be included in the review: (i) the types of participants; (ii) the types of research design; and (iii) the types of outcome measures. To be included a study has to meet all criteria. Types of participants,The participants included in the review were healthy term infants and healthy children up to the age of 16 years. Studies that focused on preterm infants, and infants and young children with serious illness or congenital malformations were excluded. However, some total population studies did include these children. Types of research design, It became evident early in the review process that very few randomised controlled trials had been conducted. A decision was made to include observational epidemiological designs, specifically prospective cohort studies and, in the case of sudden infant death syndrome research, case,control studies. Purely descriptive and cross-sectional studies were excluded, as were qualitative studies and all other forms of evidence. A number of criteria have been proposed to establish causation in the scientific and medical literature. These key criteria were applied in the review process and are described as follows: (i) consistency and unbiasedness of findings; (ii) strength of association; (iii) temporal sequence; (iv) dose,response relationship; (v) specificity; (vi) coherence with biological background and previous knowledge; (vii) biological plausibility; and (viii) experimental evidence. Studies that did not meet the requirement of appropriate temporal sequencing of events and studies that did not present an estimate of the strength of association were not included in the final review. Types of outcome measures,Our specific interest was pacifier use related to: ,breast-feeding; ,sudden infant death syndrome; ,infection; ,dental malocclusion. Studies that examined pacifier use related to procedural pain relief were excluded. Studies that examined the relationship between pacifier use and gastro-oesophageal reflux were also excluded as this information has been recently presented as a systematic review. Search strategy, The review comprised published and unpublished research literature. The search was restricted to reports published in English, Spanish and German. The time period covered research published from January 1960 to October 2003. A protocol developed by New Zealand Health Technology Assessment was used to guide the search process. The search comprised bibliographic databases, citation searching, other evidence-based and guidelines sites, government documents, books and reports, professional websites, national associations, hand search, contacting national/international experts and general internet searching. Assessment of quality, All studies identified during the database search were assessed for relevance to the review based on the information provided in the title, abstract and descriptor/MeSH terms, and a full report was retrieved for all studies that met the inclusion criteria. Studies identified from reference list searches were assessed for relevance based on the study title. Keywords included: dummy, dummies, pacifier(s), soother(s), comforter(s), non-nutritive sucking, infant, child, infant care. Initially, studies were reviewed for inclusion by pairs of principal investigators. Authorship of articles was not concealed from the reviewers. Next, the methodological quality of included articles was assessed independently by groups of three or more principal investigators and clinicians using a checklist. All 20 studies that were accepted met minimum set criteria, but few passed without some methodological concern. Data extraction, To meet the requirements of the Joanna Briggs Institute, reasons for acceptance and non-acceptance at each phase were clearly documented. An assessment protocol and report form was developed for each of the three phases of review. The first form was created to record investigators' evaluations of studies included in the initial review. Those studies that failed to meet strict inclusion criteria were excluded at this point. A second form was designed to facilitate an in-depth critique of epidemiological study methodology. The checklist was pilot tested and adjustments were made before reviewers were trained in its use. When reviewers could not agree on an assessment, it was passed to additional reviewers and discussed until a consensus was reached. At this stage, studies other than cohort, case,control and randomised controlled trials were excluded. Issues of clarification were also addressed at this point. The final phase was that of integration. This phase, undertaken by the principal investigators, was assisted by the production of data extraction tables. Through a process of trial and error, a framework was formulated that adequately summarised the key elements of the studies. This information was tabulated under the following headings: authors/setting, design, exposure/outcome, confounders controlled, analysis and main findings. Results, With regard to the breast-feeding outcome, 10 studies met the inclusion criteria, comprising two randomised controlled trials and eight cohort studies. The research was conducted between 1995 and 2003 in a wide variety of settings involving research participants from diverse socioeconomic and cultural backgrounds. Information regarding exposure and outcome status, and potential confounding factors was obtained from: antenatal and postnatal records; interviews before discharge from obstetric/midwifery care; post-discharge interviews; and post-discharge postal and telephone surveys. Both the level of contact and the frequency of contact with the informant, the child's mother, differed widely. Pacifier use was defined and measured inconsistently, possibly because few studies were initiated expressly to investigate its relationship with breast-feeding. Completeness of follow-up was addressed, but missing data were not uniformly identified and explained. When comparisons were made between participants and non-participants there was some evidence of differential loss and a bias towards families in higher socioeconomic groups. Multivariate analysis was undertaken in the majority of studies, with some including a large number of sociodemographic, obstetric and infant covariates and others including just maternal age and education. As might be expected given the inconsistency of definition and measurement, the relationship between pacifier use and breast-feeding was expressed in many different ways and a meta-analysis was not appropriate. In summary, only one study did not report a negative association between pacifier use and breast-feeding duration or exclusivity. Results indicate an increase in risk for a reduced overall duration of breast-feeding from 20% to almost threefold. The data suggest that very infrequent use may not have any overall negative impact on breast-feeding outcomes. Six sudden infant death syndrome case,control studies met the criteria for inclusion. The research was conducted with information gathered between 1984 and 1999 in Norway, UK, New Zealand, the Netherlands and USA. Exposure information was obtained from a variety of sources including: hospital and antenatal records, death scene investigation, and interview and questionnaire. Information for cases was sought within 2 days after death, within 2,4 weeks after death and in one study between 3 and 11 years after death. Information for controls was sought from as early as 4 days of a nominated sudden infant death syndrome case, to between 1 and 7 weeks from the case date, and again in one study some 3,11 years later. In the majority of the studies case ascertainment was determined by post-mortem. Pacifier use was again defined and measured somewhat inconsistently. All studies controlled for confounding factors by matching and/or using multivariate analysis. Generally, antenatal and postnatal factors, as well as infant care practices, and maternal, family and socioeconomic issues were considered. All five studies reporting multivariate results found significantly fewer sudden infant death syndrome cases used a pacifier compared with controls. That is, pacifier use was associated with a reduced incidence of sudden infant death syndrome. These results indicate that the risk of sudden infant death syndrome for infants who did not use a pacifier in the last or reference sleep was at least twice, and possibly five times, that of infants who did use a pacifier. Three studies reported a moderately sized positive association between pacifier use and a variety of infections. Conversely, one study found no positive association between pacifier use at 15 months of age and a range of infections experienced between the ages of 6 and 18 months. Given the limited number of studies available and the variability of results, no meaningful conclusions could be drawn. Five cohort studies and one case,control study focused on the relationship between pacifier use and dental malocclusion. Not one of these studies reported a measure of association, such as an estimate of relative risk. It was therefore not possible to include these studies in the final review. Implications for practice, It is intended that this review be used as the basis of a ,best practice guideline', to make health professionals aware of the research evidence concerning these health and developmental consequences of pacifier use, because parents need clear information on which they can base child care decisions. With regard to the association between pacifier use and infection and dental malocclusion it was found that, due to the paucity of epidemiological studies, no meaningful conclusion can be drawn. There is clearly a need for more epidemiological research with regard to these two outcomes. The evidence for a relationship between pacifier use and sudden infant death syndrome is consistent, while the exact mechanism of the effect is not well understood. As to breast-feeding, research evidence shows that pacifier use in infancy is associated with a shorter duration and non-exclusivity. It is plausible that pacifier use causes babies to breast-feed less, but a causal relationship has not been irrefutably proven. Because breast-feeding confers an important advantage on all children and the incidence of sudden infant death syndrome is very low, it is recommended that health professionals generally advise parents against pacifier use, while taking into account individual circumstances.

    chan d.n.s., lui l.y.y. & so w.k.w. (2010) Effectiveness of exercise programmes on shoulder mobility and lymphoedema after axillary lymph node dissection for breast cancer: systematic review. Journal of Advanced Nursing,66(9), 1902,1914. Abstract Aim., This article is a report of a review of the effectiveness of exercise programmes on shoulder mobility and lymphoedema in postoperative patients with breast cancer having axillary lymph node dissection, as revealed by randomized controlled trials. Background., Breast cancer is the most common malignancy in women. After surgery, the most common postoperative complications are reduced range of motion in the shoulder, muscle weakness in the upper extremities, lymphoedema, pain and numbness. To reduce these impairments, shoulder exercises are usually prescribed. However, conflicting results regarding the effect and timing of such exercises have been reported. Data sources., Studies were retrieved from a systematic search of published works over the period 2000,2009 indexed in the Cumulative Index to Nursing and Allied Health Literature, Ovid Medline, the British Nursing Index, Proquest, Science Direct, Pubmed, Scopus and the Cochrane Library, using the combined search terms ,breast cancer', ,breast cancer surgery', ,exercise', ,lymphoedema', ,shoulder mobility' and ,randomized controlled trials'. Methods., A quantitative review of effectiveness was carried out. Studies were critically appraised by three independent reviewers, and categorized according to levels of evidence defined by the Joanna Briggs Institute. Results., Six studies were included in the review. Early rather than delayed onset of training did not affect the incidence of postoperative lymphoedema, but early introduction of exercises was valuable in avoiding deterioration in range of shoulder motion. Conclusion., Further studies are required to investigate the optimal time for starting arm exercises after this surgery. Nurses have an important role in educating and encouraging patients to practise these exercises to speed up recovery. [source]


    Pain assessment in older people with dementia: literature review

    Abstract Title.,Pain assessment in older people with dementia: literature review. Aim., This paper is a report of a literature review conducted to identify barriers to successful pain assessment in older adults with dementia and possible strategies to overcome such barriers. Background., Pain is frequently undetected, misinterpreted, or inaccurately assessed in older adults with cognitive impairment. These people are often unable to articulate or convey how they feel and are often perceived as incapable of experiencing or recalling pain. Data sources., Searches were conducted of CINAHL, Medline and other databases for the period 1993,2007 using the search terms pain, dementia, assess*, barrier* and obstacle*. Methods., Studies were critically appraised by two independent reviewers. Data were extracted using instruments specifically developed for the review. Studies were categorized according to levels of evidence defined by the Australian National Health and Medical Research Council and Joanna Briggs Institute. Results., Perceived barriers to successful pain assessment in people with dementia included lack of recognition of pain, lack of sufficient education and/or training, misdiagnosis or late diagnosis, and non-use of assessment tools. Barriers related to people with dementia included insufficient evidence, the possibility of a ,no pain' subset of people with dementia, type of pain, and stoical attitudes. Strategies proposed as means of overcoming these barriers included knowing the person, knowing by diversity/intuitive perception, education and training, and use of adequate tools. Conclusion., More extensive education and training about the relationship between pain and dementia are urgently needed, as is the development and implementation of an effective pain assessment tool specifically designed to detect and measure pain in older adults with all stages of dementia.
