Applications of implementation science frameworks, models and theories in disparities-focused cancer screening interventions: a scoping review protocol

BACKGROUND

Implementation science (IS) frameworks, models and theories (FMTs) have gained popularity in guiding the implementation and evaluation of evidence-based interventions (EBIs) for cancer screening. However, there are significant research gaps in understanding their applications in cancer health disparities contexts. This paper outlines a scoping review protocol designed to explore the utilisation of IS FMTs in cancer screening EBIs to inform intervention designs and adaptations.

METHODS AND ANALYSIS

This scoping review protocol adheres to Arksey and O'Malley's five-step methodological framework for conducting scoping studies. Search strategies were conducted in five bibliographic databases: Ovid MEDLINE, PubMed, Scopus, Web of Science and EMBASE. The search was run on 22 June 2023 with an English language filter and a date limit of 2001-current. Two reviewers will independently screen studies for inclusion and exclusion criteria. A third reviewer will be consulted, where appropriate at any of the review stages, to achieve consensus or resolve conflicts. Data will be collected, managed and analysed using Covidence. A narrative synthesis, based on Popay et al's methodology, will guide reporting and summarisation of results. The review will adhere to the PRISMA Extension for Scoping Reviews guidelines.

ETHICS AND DISSEMINATION

This scoping review is a novel approach for examining a growing corpus of research literature on IS FMT applications used in cancer screening EBIs. As a secondary analysis, this scoping review does not require approval from an institutional review board. We anticipate the review will produce insightful information (eg, challenges, key areas for future directions) on the applications of IS TMFs in designing, deploying and testing EBIs for populations experiencing cancer screening disparities. We will disseminate the results through journals and conferences targeting IS and cancer prevention researchers and practitioners.

Exploring factors associated with preferences for human papillomavirus (HPV) self-sampling among racially- and ethnically-diverse women in Minnesota: A cross-sectional study

Pap tests are still underutilized by minority women due to limited awareness of cervical cancer screening (CCS), inadequate health care access, and cultural or religious beliefs. Human papillomavirus (HPV) self-sampling, a new CCS tool, has demonstrated potential to overcome some of these barriers. In 2021, women aged 30-65 years old were recruited across Minnesota to complete an online survey. The survey assessed five outcome measures related to HPV self-sampling: (1) awareness of test; (2) self-efficacy to conduct test; (3) location preference of test (clinic vs. home); 4) collector preference (self vs. clinician); and (5) preference of CCS strategy (HPV self-sampling vs. Pap test). Modified Poisson regressions tested associations between sociodemographic variables and outcomes. A total of 420 women completed the survey, of which 32.4% identified as Non-Hispanic white, 22.2% as Hispanic, 12.6% as Black/African-American, 28.3% as Asian, 1.9% as American Indian/Alaskan Native, and 1.4% as more than two races. Few women had heard of HPV self-sampling (6.5%), but a majority reported high self-efficacy to perform self-sampling (75.3%). Women also reported higher preferences for completing an HPV test in the clinic (52.2%) and for performing a self-collected HPV test themselves (58.7%), yet would choose a traditional Pap test over HPV self-sampling (56.0%). The low level of HPV self-sampling awareness, across all racial/ethnic groups, suggests a strong opportunity to promote widespread educational efforts around this new tool. Future HPV self-sampling research efforts should examine educational interventions targeted at healthcare providers to educate and encourage women on the importance of self-collection options.

Asian American adolescent e-cigarette use and associated protective factors: Heterogeneity in a statewide sample

OBJECTIVES

This study characterized variation in e-cigarette use patterns and related protective factors by ethnicity among Asian American adolescents.

METHODS

Multivariable logistic regressions modelled associations between ethnic group, 6 protective factors (college aspirations, internal developmental assets, positive teacher engagement, family caring, and peer and parent anti-smoking norms), and past 30-day e-cigarette use, adjusting for covariates among 10,482 8th, 9th, and 11th grade Asian American respondents to the 2019 Minnesota Student Survey. Interaction terms (protective factor × ethnic group) were used in 6 subsequent regression models to examine whether the association between each protective factor and e-cigarette use differed as a function of ethnic group.

RESULTS

Respondents included 9.0% Indian, 0.3% Burmese, 7.9% Chinese, 2.5% Filipino, 25.0% Hmong, 3.2% Karen, 4.6% Korean, 2.7% Laotian, 8.2% Vietnamese, 7.5% other, 7.5% multi-ethnic, and 21.6% multi-racial adolescents. E-cigarettes were the predominant form of tobacco use. Laotian and multi-racial groups reported the highest e-cigarette use (16.6% and 16.3%), whereas Chinese and Asian Indians reported the lowest (4.7% and 5.0%). Strong peer anti-smoking norms, higher internal developmental assets scores, and positive teacher engagement were associated with lower odds of e-cigarette use across groups, with significant interactions for internal developmental assets by ethnicity.

CONCLUSIONS

E-cigarettes are the most prevalent tobacco product used by Asian adolescents in Minnesota, with notable heterogeneity by ethnicity. While most established protective factors appeared to function similarly for Asian adolescents, others differed, underscoring the importance of disaggregating data by ethnicity to inform the tailoring of prevention and control strategies for these ethnic groups.

Abstract P026: Exploring factors associated with preferences for human papillomavirus (HPV) self-sampling among racially-and ethnically-diverse women: a cross-sectional study

Background: Cervical cancer rates have declined since the implementation of cervical cancer screening methods such as Pap tests. However, Pap tests are still underutilized by many minority women due to limited awareness about human papillomavirus (HPV) and cervical cancer, difficulties accessing health care services, and cultural or religious beliefs. HPV self-sampling has been proposed as an alternative to overcome some of these barriers. This study aimed to assess awareness, self-efficacy, and preferences of HPV self-sampling among racially- and ethnically-diverse women. Methods: From May – November 2021, women, ages 30-65 years old, were recruited in person and virtually to complete an online survey. The survey included 15 sociodemographic questions and five outcome measures related to HPV self-sampling: (1) awareness of test; (2) self-efficacy to conduct test; (3) location preference of test (clinic vs. home); 4) collector preference for screening strategy (self-collected vs. clinician-collected); and 5) preference of cervical cancer screening strategy (HPV self-sampling vs. Pap test). Modified Poisson regression was conducted to assess exploratory associations between sociodemographic variables and each outcome measure; relative risks were adjusted for age. Results: A total of 420 women completed the online survey, of which 32.4% identified as non-Hispanic white, 22.2% as Hispanic, 12.6% as Black/African American, 28.3% as Asian, 1.9% as American Indian/Alaskan Native, and 1.4% as more than two races. The majority of women had not heard of HPV self-sampling (93.5%) but reported high self-efficacy (75.3%). Women also reported higher preferences for completing an HPV test in the clinic (52.2%) and for performing a self-collected HPV test themselves (58.7%) yet would choose a traditional Pap test over HPV self-sampling (56.0%). Conclusion: The low level of HPV self-sampling awareness, across all racial and ethnic groups, suggests a strong opportunity to promote widespread educational efforts around this new tool. While many women, including those that are racially- and ethnically-diverse, still prefer the Pap test, the biggest barrier to their potential uptake of HPV self-sampling is a strong reliance on provider expertise. Future research should leverage the provider role in HPV self-sampling interventions as well as explore the feasibility of home-based or clinic-based HPV self-sampling approaches.

Health care personnel's perspectives on human papillomavirus (HPV) self-sampling for cervical cancer screening: a pre-implementation, qualitative study

BACKGROUND

Persistent infection with high-risk human papillomavirus (hrHPV) types is a well-documented cause of cervical cancer. Since the implementation of cervical cancer screening methods (e.g., Pap tests), cervical cancer rates have declined. However, Pap tests are still unacceptable to many women and require complex infrastructure and training. Self-sampling techniques for collecting HPV specimens (or "HPV self-sampling") have been proposed as a possible alternative to overcome these barriers. The objective of this study was to capture perspectives from health care personnel (providers, leaders, and clinic staff) across primary care systems on the potential implementation of an HPV self-sampling practice.

METHODS

Between May and July 2021, a study invitation was emailed to various health care professional networks across the Midwest, including a snowball sampling of these networks. Eligible participants were invited to a 45-60-min Zoom-recorded interview session and asked to complete a pre-interview survey. The survey collected sociodemographics on age, occupation, level of educational attainment, race/ethnicity, gender, and awareness of HPV self-sampling. The semi-structured interview was guided by the Consolidated Framework for Implementation Research and asked participants about their views on HPV self-sampling and its potential implementation. All interviews were audio-recorded, transcribed, and analyzed using NVivo 12.

RESULTS

Key informant interviews were conducted with thirty health care personnel-13 health care providers, 6 clinic staff, and 11 health care leaders-from various health care systems. Most participants had not heard of HPV self-sampling but reported a general enthusiasm for wanting to implement it as an alternative cervical cancer screening tool. Possible barriers to implementation were knowledge of clinical evidence and ease of integration into existing clinic workflows. Potential facilitators included the previous adoption of similar self-sampling tools (e.g., stool-based testing kits) and key decision-makers.

CONCLUSION

Although support for HPV self-sampling is growing, its intervention's characteristics (e.g., advantages, adaptability) and the evidence of its clinical efficacy and feasibility need to be better disseminated across US primary care settings and its potential adopters. Future research is also needed to support the integration of HPV self-sampling within various delivery modalities (mail-based vs. clinic-based).

Belonging to Three Worlds: Somali Adolescent-Parent Relationships in the United States and Implications for Tobacco Prevention

Immigrant family relationships help to buffer the adolescent adoption of health risk behaviors but can be strained by post-immigration structural and cultural barriers. This study qualitatively examines how Somali adolescent-parent relationship factors influence Somali adolescent tobacco use and identifies areas for further family support to prevent Somali adolescent tobacco use. We conducted fifteen key informant interviews with professionals serving the Somali community in clinical, educational, religious, or other community organization roles in one Minnesota metropolitan region. Data were collected and analyzed using approaches rooted in Grounded Theory. Key informants contrasted parenting experiences in Somalia with those in the United States and described how four key factors-structural and cultural barriers, multicultural identity formation, evolving parental expectations and responsibilities, and shifting family resources and support-have influenced Somali parent-child relationship quality and function following immigration. Informants shared the implications of these factors on parental ability to address adolescent tobacco use and discussed potential strategies to support parents that fell into two categories: assisting parents in adapting their parenting approaches to a new context and supporting knowledge and skill development in addressing tobacco use prevention specifically. Incorporating strategies that support Somali parents in their evolving parental roles and attend to structural and cultural barriers to tobacco prevention are essential to consider when developing family-centered tobacco prevention interventions in this population.

Applying the Healthy Eating Index-2015 in a Sample of Choice-Based Minnesota Food Pantries to Test Associations Between Food Pantry Inventory, Client Food Selection, and Client Diet

BACKGROUND

Food pantry clients are at a high risk for diet-related chronic disease and suboptimal diet. Relatively little research has examined diet quality measures in choice-based food pantries where clients can choose their own food.

OBJECTIVE

This study tested whether the diet quality scores for food at the pantry were associated with client food selection scores, and whether client food selection scores at the pantry were associated with client diet intake scores.

DESIGN

This cross-sectional regression analysis, part of a larger evaluation study (SuperShelf), used baseline data from client and food pantry surveys, food pantry inventories, assessments of client food selections ("client carts"), and single 24-hour client dietary recalls.

PARTICIPANTS/SETTING

The analysis includes 316 clients who completed a survey (282 of whom completed a dietary recall measure) from one of 16 choice-based Minnesota food pantries during 2018-2019. Adult English, Spanish, or Somali-speaking clients were eligible in the case that they had selected food on the day of recruitment at their food pantry visit.

MAIN OUTCOME MEASURES

A Healthy Eating Index-2015 (HEI-2015) Total score and 13 subcomponent scores were calculated for: pantry food inventories of food available on the shelf, client carts, and a 24-hour client dietary recall.

STATISTICAL ANALYSIS

Descriptive statistics were generated for client and food pantry characteristics, and for HEI-2015 Total score and subcomponent scores. Linear regression models tested the association between HEI-2015 Total score and subcomponent scores for food pantry inventory and client carts, and for client carts and dietary recalls, adjusted for covariates.

RESULTS

Food pantry inventory HEI-2015 Total score averaged 65.1, client cart Total score averaged 60.8, and dietary recall Total score averaged 50.9. The diet quality scores for inventory were not associated with client cart scores, except for Added Sugars (P = .005). Client cart HEI-2015 Total score was positively associated with client diet HEI-2015 Total score (P = .002) and associations for Total Fruits, Whole Fruits, Total Vegetables, Greens and Beans, Whole Grains, Seafood and Plant Proteins, and Added Sugars subcomponents were statistically significant.

CONCLUSIONS

In choice-based Minnesota food pantries, the diet quality of food selected by clients was positively associated with client diet quality.

Key Informant Perspectives on Somali Adolescent Tobacco Use: Contextualizing Influences and Prevention Opportunities

INTRODUCTION

Somali American adolescent tobacco use has increased over the past decade amid a high prevalence of tobacco use among Somali American adults. While established adolescent tobacco use determinants may apply for Somali youth, a deeper understanding of these influences is imperative to the development of effective prevention strategies for this population. This study aimed to identify risk and protective factors influencing Somali American adolescent tobacco use decision making and potential family and community roles in tobacco prevention.

METHOD

We conducted 15 semistructured, in-depth interviews with 12 Somali and 3 non-Somali professionals serving Minnesotan metropolitan Somali communities in clinical, educational, religious, and other community organizations. Grounded Theory informed our data collection and analysis.

RESULTS

Key informants cited three major influences on Somali adolescent tobacco use: evolving norms and increasing exposure to tobacco products in the United States, low risks perception, especially for waterpipes, and conflicting interpretations of faith. Informants highlighted the important roles of families in Somali youth tobacco prevention while acknowledging areas where families would benefit from greater support. Proposed sources of support included faith communities and nonparental, ethnically similar adult mentors. Informants acknowledged challenges to addressing youth tobacco prevention in clinics and underscored the importance of youth involvement in developing prevention strategies.

CONCLUSIONS

Our results indicate Somali adolescent tobacco prevention efforts should address the evolving tobacco use exposures and norms, low risk perceptions, and clarify faith messaging. Effective strategies may include strengthening family-based tobacco prevention approaches that also engage faith and other community leaders along with youth themselves.

Personal respiratory protection and tuberculosis: national evidence-based guidelines in England and Wales

In our review published in the previous issue, we noted that contradictory infection prevention and control recommendations have resulted in confusion in practice and inconsistent use of personal respiratory protection when caring for patients with infectious respiratory tuberculosis in hospitals and other healthcare facilities. Recent national evidence-based guidelines in England and Wales have sought to clarify this issue by making firm recommendations for tuberculosis infection prevention and control. We describe and discuss this guidance, focusing on our concerns over the illogical recommendations for the use of personal respiratory protection.

Tuberculosis and infection control: a review of the evidence

xposure to patients with infectious tuberculosis is a well-recognised hazard of health care and although the risks associated with this hazard cannot be completely eliminated, they can be controlled and minimised. Risk reduction strategies rely upon a hierarchy of control measures to prevent the nosocomial transmission of tuberculosis in healthcare settings. In this article, the authors discuss the background to these strategies and review the evidence that underpins clinically effective administrative and engineering controls and personal respiratory protection. The authors conclude with recommendations and guide readers to further sources of reliable information.

Addressing perinatal depression in a group of underserved urban women: a focus group study

BACKGROUND

Perinatal mental health problems are common complications of pregnancy that can go undetected and untreated. Research indicated that mental health complications are more prevalent in women from disadvantaged communities, yet women from these communities often experience barriers to accessing treatments and interventions. Untreated depression during pregnancy can lead to poor self-care, increased substance abuse, poor obstetrical outcomes, developmental delay in children, and increased risk of postpartum depression. In this study we investigated the perceived perinatal mental health needs of our participants and they wanted to address their perceived needs.

METHODS

In this qualitative study, we invited women who resided in an underserved, urban community who were pregnant or who delivered within the past year to participate in focus groups.

RESULTS

Thirty-seven women participated in seven focus groups. Thirteen themes emerged which were described in relation to mental health needs, help currently accessed and the type of support wanted. The themes included the various mental health needs including dealing with changing moods, depression, feelings of isolation, worrying and a sense of being burdened. Women described using a limited range of supports and help. Participants expressed a preference for mental health support that was empowerment focused in its orientation, including peer support. Women also described the compounding effect that social and economic stresses had on their mental health.

CONCLUSIONS

Participants wanted access to a greater range of supports for mental health than were currently available to them, including peer support, and wanted assistance in addressing social and economic needs. These findings offer a challenge to further broaden the types of services offered to women, and demonstrate that those services need to be responsive to the challenging contexts of women's lives. Integrating women's views and experiences into the development of services may help to overcome barriers to care.

Impact on staff of improving access to the school breakfast program: a qualitative study

BACKGROUND

Project BREAK! was designed to test the efficacy of an intervention to increase student participation in the reimbursable School Breakfast Program (SBP). Two schools developed grab-n-go menus, added convenient serving locations, and allowed eating in the hallway. This follow-up study investigated faculty and staff perspectives of how the SBP changes influenced schools.

METHODS

Project BREAK! high schools were located near Minneapolis, Minnesota, enrolled over 1200 students each and were 70% to 90% white. Interviews with school personnel (N = 11) and focus groups with teachers (N = 16) from the 2 intervention schools were conducted. The Diffusion of Innovation (DOI) framework guided the question development.

RESULTS

Analysis of the interviews identified the following DOI constructs as most prominently mentioned by school personnel and teachers: advantages for students and faculty/staff, minimal staff time required, communication of the changes, support of social relations between students and faculty/staff and trialability of the program.

CONCLUSION

There appears to be numerous advantages for both students and school personnel to improving SBP access. The relative advantages of Project BREAK! appear to outweigh the negatives associated with extra time and effort required by staff. Communication about the changes is an area that needs strengthening.

epic3: national evidence-based guidelines for preventing healthcare-associated infections in NHS hospitals in England

National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were originally commissioned by the Department of Health and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians. Following extensive consultation, they were first published in January 2001(1) and updated in 2007.(2) A cardinal feature of evidence-based guidelines is that they are subject to timely review in order that new research evidence and technological advances can be identified, appraised and, if shown to be effective for the prevention of HCAI, incorporated into amended guidelines. Periodically updating the evidence base and guideline recommendations is essential in order to maintain their validity and authority. The Department of Health commissioned a review of new evidence and we have updated the evidence base for making infection prevention and control recommendations. A critical assessment of the updated evidence indicated that the epic2 guidelines published in 2007 remain robust, relevant and appropriate, but some guideline recommendations required adjustments to enhance clarity and a number of new recommendations were required. These have been clearly identified in the text. In addition, the synopses of evidence underpinning the guideline recommendations have been updated. These guidelines (epic3) provide comprehensive recommendations for preventing HCAI in hospital and other acute care settings based on the best currently available evidence. National evidence-based guidelines are broad principles of best practice that need to be integrated into local practice guidelines and audited to reduce variation in practice and maintain patient safety. Clinically effective infection prevention and control practice is an essential feature of patient protection. By incorporating these guidelines into routine daily clinical practice, patient safety can be enhanced and the risk of patients acquiring an infection during episodes of health care in NHS hospitals in England can be minimised.

The introduction of a healthy reading scheme for people with mental health problems: usage and experiences of health professionals and library staff

Objective This study aimed to explore utilisation of a 'healthy reading' service and to offer further insight into improving the processes and uptake of book prescribing so that more people have the opportunity to access this treatment.Method Semi-structured interviews with librarians and prescribers. Collection of routine library data.Results The scheme was thought to have been well organised, and borrowings by library users were high. A prescription was presented for 17% of borrowings. Health professionals who already used bibliotherapy in their practice were particularly positive about the scheme. There is potential to increase prescribing from other health professionals, especially general practitioners (GPs). Barriers to use included remembering the service, lack of knowledge about resources, concerns that patients would find resources difficult to use, and the time required within the consultation.Conclusion This research showed that the healthy reading scheme provided a useful treatment option for patients with mild mental health problems and was also well used by library members. Regular reminders about the service and training for prescribers have the potential to increase patient access to resources. Further research is required to determine whether this model of bibliotherapy meets the needs of users of healthy reading materials in accessing the service.Healthy reading has a place in stepped care models for improving mental health at both community and primary care levels. As well as being used as an adjunct therapy it could, in some cases, be an alternative to antidepressant prescribing and help reduce waiting lists for more staff-intensive psychological therapies.

Supporting evidence-based infection prevention and control practice in the National Health Service in England. The NHS/TVU/Intuition Approach

All successful strategies for preventing healthcare-associated infections require a multifaceted evidence-based approach that includes providing practitioners with the best evidence for clinically effective practice and then supporting them to understand and use this evidence to minimise infection risks and increase patient safety. This paper describes how national evidence-based guidelines from the Department of Health and the National Institute for Health and Clinical Excellence in England form the foundations for ensuring the availability of best evidence to practitioners, and how the development of an associated e-learning/blended learning programme is now supporting all NHS staff to effectively use this evidence to protect patients from the risk of preventable infections during care.

Uniform: an evidence review of the microbiological significance of uniforms and uniform policy in the prevention and control of healthcare-associated infections. Report to the Department of Health (England)

A systematic search and quality assessment of published literature was conducted to establish current knowledge on the role of healthcare workers uniforms' as vehicles for the transfer of healthcare-associated infections. This review comprised a systematic search of national and international guidance, published literature and data on recent advances in laundry technology and processes. We found only a small number of relevant studies that provided limited evidence directly related to the decontamination of uniforms. Studies concerning domestic laundry processes are small scale and largely observational. Current practice and guidance for laundering uniforms is extrapolated from studies of industrial hospital linen processing. Healthcare workers' uniforms, including white coats, become progressively contaminated in use with bacteria of low pathogenicity from the wearer and of mixed pathogenicity from the clinical environment and patients. The hypothesis that uniforms/clothing could be a vehicle for the transmission of infections is not supported by existing evidence. All components of the laundering process contribute to the removal or killing of micro-organisms on fabric. There is no robust evidence of a difference in efficacy of decontamination of uniforms/clothing between industrial and domestic laundry processes, or that the home laundering of uniforms provides inadequate decontamination.

epic2: National evidence-based guidelines for preventing healthcare-associated infections in NHS hospitals in England

National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were commissioned by the Department of Health (DH) and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians. Following extensive consultation, they were published in January 2001. These guidelines describe the precautions healthcare workers should take in three areas: standard principles for preventing HCAI, which include hospital environmental hygiene, hand hygiene, the use of personal protective equipment, and the safe use and disposal of sharps; preventing infections associated with the use of short-term indwelling urethral catheters; and preventing infections associated with central venous catheters. The evidence for these guidelines was identified by multiple systematic reviews of experimental and non-experimental research and expert opinion as reflected in systematically identified professional, national and international guidelines, which were formally assessed by a validated appraisal process. In 2003, we developed complementary national guidelines for preventing HCAI in primary and community care on behalf of the National Collaborating Centre for Nursing and Supportive Care (National Institute for Healthand Clinical Excellence). A cardinal feature of evidence-based guidelines is that they are subject to timely review in order that new research evidence and technological advances can be identified, appraised and, if shown to be effective in preventing HCAI, incorporated into amended guidelines. Periodically updating the evidence base and guideline recommendations is essential in order to maintain their validity and authority. Consequently, the DH commissioned a review of new evidence published following the last systematic reviews. We have now updated the evidence base for making infection prevention and control recommendations. A critical assessment of the updated evidence indicated that the original epic guidelines published in 2001 remain robust, relevant and appropriate but that adjustments need to be made to some guideline recommendations following a synopsis of the evidence underpinning the guidelines. These updated national guidelines (epic2) provide comprehensive recommendations for preventing HCAI in hospitals and other acute care settings based on the best currently available evidence. Because this is not always the best possible evidence, we have included a suggested agenda for further research in each section of the guidelines. National evidence-based guidelines are broad principles of best practice which need to be integrated into local practice guidelines. To monitor implementation, we have suggested key audit criteria for each section of recommendations. Clinically effective infection prevention and control practice is an essential feature of protecting patients. By incorporating these guidelines into routine daily clinical practice, patient safety can be enhanced and the risk of patients acquiring an infection during episodes of healthcare in NHS hospitals in England can be minimised.

A systematic review of the evidence for interventions for the prevention and control of meticillin-resistant Staphylococcus aureus (1996–2004): report to the Joint MRSA Working Party (Subgroup A)

A systematic review was undertaken of the evidence published between 1996 and 2004 on the effectiveness, and associated economic costs, of a range of interventions to prevent and control the transmission of meticillin-resistant Staphylococcus aureus (MRSA) in hospital settings. The review questions focused on screening, patient isolation, use of decolonization strategies, feedback of surveillance data, and environmental hygiene interventions. The reviewers assessed evidence from four recent systematic reviews, 24 non-experimental descriptive studies, five economic evaluations and one recently revised international guideline. The methodological quality of studies retrieved was such that there is currently insufficient high-quality evidence for infection prevention and control interventions in the fields identified for this review. However, evidence from clinically based, non-experimental studies does provide support for the continued use of a range and combination of interventions that contribute to the prevention and control of MRSA within acute hospitals and long-term-care settings. Well-conducted economic evaluations reporting the economic benefits arising from infection prevention and control interventions are lacking.

Kaleidoscope: a 5-year action research project to develop nursing confidence in caring for patients with HIV disease in west India

As the national epidemic of human immunodeficiency virus (HIV) infection and the acquired immune deficiency syndrome (AIDS) epidemic rapidly unfolds in India, nurses have to acquire new competencies in order to provide appropriate care to an increasing number of affected persons. In response, an Indo-British action research collaboration was initiated to build clinical confidence and facilitate relevant changes in nursing practice. During a 10-day educational programme, a change intervention was applied, culminating in the development of individual and partnership action plans focused on bringing about changes in nursing practice within well-defined fields of action. Following implementation of their action plans, participants were reassembled 12 months later for a follow-up workshop to discuss their progress and describe those factors that either helped or hindered them in achieving their objectives. They then developed new action plans for the next 12-month period. This article reports on the results from six cohorts (n = 160) in India who participated in this project between 1995 and 1999. Action plans were frequently focused on infection control, primary prevention, curriculum development in preregistration nursing programmes and in-service nursing education. The majority of participants reported significant achievements in realizing their action-plan objectives. Data analysis revealed that the change intervention itself, together with multidisciplinary support from colleagues, the senior status of the participant, and anticipating and attending the follow-up workshop, were all positively correlated with achievement. The lack of personal authority and resistance from managers were the two major factors negatively correlated with achievement. This method for facilitating changes in nursing practice has been successfully adapted and replicated by our group in other countries.

Adherence to antiretroviral therapy: appropriate use of self-reporting in clinical practice

PURPOSE

This study investigated the factors that may affect adherence to antiretroviral therapy in people with HIV infection and compared the use of three self-report tools to determine client adherence.

METHOD

A descriptive, cross-sectional study of 260 HIV-infected clients attending nine HIV outpatient centers in England was conducted using researcher-administered instruments. Self-reports of adherence were assessed using the Morisky Medication Adherence Scale (MMAS), Reported Adherence to Medication Scale (RAM), and the Patient Adjustment to Medication Scale (PAM).

RESULTS

Univariate analysis of clients' self-reports indicated a number of associations with adherence. Significant associations with less adherent behavior identified by two or more self-report tools were the reported use of recreational drugs, p =.001; living alone, p =.041; feeling depressed, p =.02; being influenced by the media, p =.037; and lack of a close confidant, p =.037. Greater adherence was associated with clients reporting a positive mental attitude to HIV infection, p =.038. Principal component analysis (PCA) of each self-report tool identified two well-recognized constructs: intentional nonadherence and unintentional nonadherence. In addition, a third construct of following instructions was identified from PAM, a scale developed by the authors. Subsequent regression analysis failed to confirm the associations with adherence suggested by the univariate analysis.

CONCLUSION

This study suggests that the design and use of self-report tools to identify client's adherence to complex antiretroviral regimens may need to measure individual constructs of adherence to accurately assess adherence behavior.

The epic project: developing national evidence-based guidelines for preventing healthcare associated infections. Phase I: Guidelines for preventing hospital-acquired infections. Department of Health (England)

In 1998, the Department of Health (England) commissioned the first phase of national evidence-based guidelines for preventing healthcare associated infections. These focused on developing a set of standard principles for preventing infections in hospitals together with guidelines for preventing hospital-acquired infections (HAI) associated with the use of short-term indwelling ureteral catheters in acute care and with central venous catheters in acute care. These guidelines are systematically developed broad statements (principles) of good practice that all practitioners can use and which can be incorporated into local protocols. A nurse-led, multi-professional team composed of infection prevention practitioners, clinical microbiologists/retrovirologist, epidemiologists, and researchers developed the guidelines. A rigorous guideline development process was used to inform the systematic reviews, the clinical and critical appraisal of relevant evidence, and linking that evidence to evolving guidelines. Both general and specialist clinical practitioners were involved in all stages of developing these guidelines, as were representatives from relevant Royal Colleges, learned societies, other professional organisations and key stakeholders. The introduction to these guidelines describes a robust and validated guideline development model that can be used by others to develop future guidelines. This model is described in more detail in the associated technical reports that can be found on the project web site http://www.epic.tvu.ac.uk. Locating and appropriately using good quality evidence to inform guideline development in this field is challenging. Evidence from rigorously conducted experimental studies was frequently limited and consequently a range of other types of evidence were systematically retrieved and carefully appraised. The concluding discussion on implementation highlights potential issues for clinical governance and areas for future research and suggests issues that need to be addressed to allow practitioners to successfully incorporate these guidelines into routine clinical practice.

Cutaneous leishmaniasis. An unusual cause of facial swelling

Tropical disease may not figure highly in the differential diagnosis of a facial swelling in the United Kingdom but should be considered in those who have been in a tropical area. This case history documents details of the presentation and investigation of a case of leishmaniasis that appeared as a facial swelling in a 4-year-old boy who had recently returned from the Middle East.

HIV-2:The Implications

In 1983, the aetiological agent of AIDS was discovered by French scientists and was termed the 'lym- phadenopathy-associated virus' (LAV) [ 1 ]. A year later, American researchers also described this retrovirus and termed it the 'Human T-cell leukemia virus, type III' (HTLV-III) [ 2 ], Both LAV and HTLV-III were the same retrovirus and in 1986, it was agreed that the viruses which can cause AIDS be termed the 'human immunodeficiency viruses' (HIV).
