Systematic review of the effects of antimicrobial cycling on bacterial resistance rates within hospital settings.

AIMS: Antimicrobial resistance is an evolving phenomenon with alarming public health consequences. Antibiotic cycling is a widely known antimicrobial stewardship initiative that encompasses periodical shifts in empirical treatment protocols with the aim of limiting selective pressures on bacterial populations. We present a review of the evidence regarding the actual impact of antimicrobial cycling on bacterial resistance control within hospitals. METHODS: A systematic literature review was conducted using the PubMed/MedLine, Embase, CINAHL Plus and Global Health databases. RESULTS: A systematic search process retrieved a sole randomised study, and so we broadened inclusion criteria to encompass quasi-experimental designs. Fifteen studies formed our dataset including seven prospective trials and eight before-and-after studies. Nine studies evaluated cycling vs. a control group and produced conflicting results whilst three studies compared cycling with antibiotic mixing, with none of the strategies appearing superior. The rest evaluated resistance dynamics of each of the on-cycle antibiotics with contradictory findings. Research protocols differed in parameters such as the cycle length, the choice of antibiotics, the opportunity to de-escalate to narrow-spectrum agents and the measurement of indicators of collateral damage. This limited our ability to evaluate the replicability of findings and the overall policy effects. CONCLUSION: Dearth of robust designs and standardised protocols limits our ability to reach safe conclusions. Nonetheless, in view of the available data we find no reason to believe that cycling should be expected to improve antibiotic resistance rates within hospitals.

Minimizing sample bias due to stigmatized behaviours: the representativeness of participants in a cohort study of alcohol in pregnancy.

BACKGROUND: Stigmatized behaviours are often underreported, especially in pregnancy, making them challenging to address. The Alcohol and Child Development Study (ACDS) seeks to inform prevention of foetal alcohol harm, linking self-report as well as a maternal blood alcohol biomarker with child developmental outcomes. Samples were requested using passive, generic consent. The success of this approach at minimizing bias is presented comparing characteristics of women who provided samples to those who did not. METHODS: All pregnant women in the study city were sent a Patient Information Sheet (PIS) with their first NHS obstetric appointment letter. The PIS informed them that the NHS would like to take an extra blood sample for research purposes, unless they opted out. Neither the women nor the midwives were informed that the samples might be tested for an alcohol biomarker. This paper examines the extent to which women who provided the extra sample were representative of women where no sample was provided, in terms of routinely collected information: age; body mass index; area-based deprivation; previous pregnancies, abortions and caesarians; smoking status and carbon monoxide level; self-reported alcohol use, gestation and birth weight of their baby. Chi-square and Mann-Whitney U tests were used to compare groups. RESULTS: 3436 (85%) of the 4049 pregnant women who attended their appointment provided the extra sample. Women who did not were significantly younger (p < 0.001), more materially deprived (p < 0.001), and less likely to be considered for intervention based on self-reported alcohol use (p < 0.001). There were no significant differences between the two groups on other routine data. CONCLUSIONS: The use of passive consent without disclosure of the specific research focus resulted in a high level of sample provision. There was no evidence that study blinding was breached, and women who provided a sample were more likely to report alcohol consumption. Passive consent to draw additional blood for research purposes at routine antenatal venipuncture reduced sampling bias compared to asking women to give blood for an alcohol study. This methodology may be useful for other stigmatised behaviours.

Validation of US cerebral palsy growth charts using a UK cohort.

AIM: Growth charts for cerebral palsy (CP) have been constructed using data for 24 920 Californian patients, covering ages 2 to 20 years, with separate charts for the five severity levels of the Gross Motor Function Classification System (GMFCS). Our aim was to test how the data for British children with CP fit these charts, compared with conventional local charts. METHOD: US CP growth reference was reanalysed using the lambda-mu-sigma (LMS) method to allow calculation of standard deviation z-scores. Growth data for 195 children with CP in Glasgow, UK, were retrieved and converted to z-scores using the CP reference as well as the combined World Health Organization and UK 1990 growth reference (UK-WHO). RESULTS: Compared to the UK-WHO reference, measurements diverged progressively with increasing severity, with mean height for GMFCS level V being close to the second UK-WHO centile. Compared with the CP reference, mean height and weight z-scores were between the 50th and 75th centiles for all severity levels, while body mass index was just below the 50th centile. INTERPRETATION: British children with severe CP seem relatively very small when their growth data are plotted on non-CP charts, but their data for weight and body mass index fit well to US CP charts and reasonably well for height. The LMS look-up tables will make it possible to calculate z-scores and produce charts in local formats.

Awareness, attitudes and perceptions regarding HIV and PMTCT amongst pregnant women in Guinea-Bissau- a qualitative study.

BACKGROUND: The human immunodeficiency virus (HIV) continues to be a major cause of maternal and infant mortality and morbidity in sub-Saharan Africa. Prevention of mother-to-child transmission of HIV (PMTCT) strategies have proven effective in decreasing the number of children infected in utero, intrapartum and during the breastfeeding period. This qualitative study explores knowledge and perceptions of HIV amongst pregnant women, healthcare workers' experiences of the national PMTCT services, and barriers to PMTCT, during a period of programme scale-up in urban Guinea-Bissau (2010-11). METHODS: In-depth interviews were undertaken amongst 27 women and 19 key informants at local antenatal clinics and the national maternity ward in Bissau, Guinea-Bissau. RESULTS: Amongst women who had been tested for HIV, awareness and knowledge of HIV and PMTCT remained low. Testing without informed consent was reported in some cases, in particular when the test was performed around the time of delivery. Possible drivers of inadequate counselling included lack of confidentiality, suboptimal healthcare worker training, lack of time, and perceived occupational risk. Demand-side barriers to PMTCT included lack of HIV and PMTCT knowledge, customary and cultural beliefs associated with HIV and ill-health, HIV stigma and discrimination, and fear of partnership dissolution. CONCLUSIONS: Socio-cultural and operational challenges, including HIV testing without informed consent, present significant barriers to the scale-up of PMTCT services in Bissau. Strengthening local capacity for effective counselling and testing in the antenatal setting is paramount. Further research into local customary beliefs relating to HIV is warranted.

Assessing the impact of multidrug-resistant tuberculosis in children: an exploratory qualitative study.

BACKGROUND: While the prevalence of multidrug-resistant (MDR) tuberculosis (TB) is high among children in the Western Cape of South Africa, the psychosocial implications of treatment for children with MDR-TB remain poorly understood. We sought to explore how MDR-TB and its treatment impact children on an individual, familial, and social level. METHODS: Semi-structured interviews were conducted with 20 children and caregivers purposively sampled from a prospective clinical cohort of children. The sample was stratified by age at the start of treatment (children >10 years, and 5-10 years). Caregiver proxy interviews were conducted with younger children, supplemented with child interviews; older children were interviewed directly, supplemented with caregiver proxy interviews. Data were analysed using grounded theory. RESULTS: Findings revealed pill volume and adverse effects produced significant physical, psychological and academic disturbances in children. Adverse effects related to the medication were important obstacles to treatment adherence. While there appear to be no long-lasting effects in younger children, a few older children showed evidence of persisting internalised stigma. Caregivers suffered important treatment-related financial and psychological costs. Community support, notably through the continued involvement of children in strong social networks, promoted resilience among children and their families. CONCLUSIONS: We found that the current treatment regimen for childhood MDR-TB has significant psychological, academic, and financial impacts on children and their families. There is a need for psychosocial support of children and caregivers to mitigate the negative effects of community stigma, and to manage the stressors associated with chronic illness.

"Home is where the patient is": a qualitative analysis of a patient-centred model of care for multi-drug resistant tuberculosis.

BACKGROUND: Ambulatory, community-based care for multi-drug resistant tuberculosis (MDR-TB) has been found to be effective in multiple settings with high cure rates. However, little is known about patient preferences around models of MDR-TB care. Médecins Sans Frontières (MSF) has delivered home-based MDR-TB treatment in the rural Kitgum and Lamwo districts of northern Uganda since 2009 in collaboration with the Ministry of Health and the National TB and Leprosy Programme. We conducted a qualitative study examining the experience of patients and key stakeholders of home-based MDR-TB treatment. METHODS: We used semi-structured interviews and focus-group discussions to examine patients' perceptions, views and experiences of home-based treatment and care for MDR-TB versus their perceptions of care in hospital. We identified how these perceptions interacted with those of their families and other stakeholders involved with TB. Participants were selected purposively following a stakeholder analysis. Sample size was determined by data saturation being reached within each identified homogenous category of respondents: health-care receiving, health-care providing and key informant. Iterative data collection and analysis enabled adaptation of topic guides and testing of emerging themes. The grounded theory method of analysis was applied, with data, codes and categories being continually compared and refined. RESULTS: Several key themes emerged: the perceived preference and acceptability of home-based treatment and care as a model of MDR-TB treatment by patients, family, community members and health-care workers; the fear of transmission of other infections within hospital settings; and the identification of MDR-TB developing through poor adherence to and inadequate treatment regimens for DS-TB. CONCLUSIONS: Home-based treatment and care was acceptable to patients, families, communities and health-care workers and was seen as preferable to hospital-based care by most respondents. Home-based care was perceived as safe, conducive to recovery, facilitating psychosocial support and allowing more free time and earning potential for patients and caretakers. These findings could contribute to development of an adaptation of treatment approach strategy at national level.

Opening the oyster: the 2010-11 NHS reforms in England.

This opinion paper briefly considers the credibility of the announced rationale behind the current extensive reform of the NHS in light of recent research evidence about performance of the system. The paper outlines the authors' views of the history of the reform, which originates in a set of documents, produced in the late 1980s by the Centre for Policy Studies, which aimed to introduce private sector involvement throughout the NHS, and a brief report by a consultant for a health maintenance organisation in the USA. Tracking of the pro-private sector changes in the NHS demonstrates that the bill is a major step in the implementation of NHS privatisation and also delineates a roadmap for coming developments, which have been explained to corporate providers and investors seeking new profit opportunities but have not yet been debated openly with the electorate in the UK.

Ditching the single-payer system in the national health service: how the English Department of Health is learning the wrong lessons from the United States.

Reforms to the British National Health Service introduce major changes to how health care will be delivered. The core elements include the creation of new purchaser organizations, Clinical Commissioning Groups, which unlike their predecessors will be able to recruit and reject general practices and their patients without geographical restriction. The Clinical Commissioning Groups are to transition from statutory bodies to freestanding organizations, with most of their functions privatized and an increasingly privatized system of provision, In this paper, we explore the likely consequences of these proposals, drawing in particular on the experience of managed care organizations in the United States, whose approach has influenced the English proposals extensively. We argue that the wrong lessons are being learned and the English reforms are likely to fundamentally undermine the principles on which the British National Health Service was founded.

Competition-based reform of the National Health Service in England: a one-way street?

The Conservative-led government in the United Kingdom is embarking on massive changes to the National Health Service in England. These changes will create a competitive market in both purchasing and provision. Although the opposition Labour Party has stated its intention to repeal the legislation when it regains power, this may be difficult because of provisions of competition law derived from international treaties. Yet there is an alternative, illustrated by the decision of the devolved Scottish government to reject competitive markets in health care.

HIV as a chronic disease considerations for service planning in resource-poor settings.

This paper reviews the healthcare issues facing nations which have a substantial caseload of chronic HIV cases. It considers the challenges of extending antiretroviral coverage to an expanding caseload as supplier price rises and international trade agreements come into force to reduce the availability of affordable antiretrovirals just as the economic downturn restricts donor funding. It goes on to review the importance in this context of supporting adherence to drug regimens in order to preserve access to affordable antiretrovirals for those already on treatment, and of removing key barriers such as patient fees and supply interruptions. The demands of those with chronic HIV for health services other than antiretroviral therapy are considered in the light of the fearful or discriminatory attitudes of non-specialist healthcare staff due to HIV-related stigma, which is linked with the weakness of infection control measures in many health facilities. The implications for prevention strategies including those involving criminalisation of HIV transmission or exposure are briefly summarised for the current context, in which the caseload of those whose chronic HIV infection must be controlled with antiretrovirals will continue to rise for the foreseeable future.

Serve the people or close the sale? Profit-driven overuse of injections and infusions in China's market-based healthcare system.

Treatment by injection or infusion is widespread in China. Using the common cold as a tracer condition, we explored the reasons for over-prescription of injections and infusions in Guizhou, China. Interviews with prescribers, patients and key informants were supplemented by focus groups. These revealed how historical ideas encourage unnecessary use of percutaneous treatment: faith in the healing power of needles is locally attributed to association with acupuncture. Many patients and some staff believe that injections per se are therapeutic. However, the structure of health service financing and remuneration now reinforces this irrational faith. Market-based reforms have attempted to control costs and increase productivity with an incentive scheme which rewards prescribers financially for over-prescription in general and for use of injections and infusions in particular. Aggressive marketing has displaced oral treatment from health facilities into independent pharmacies, leaving doctors functioning mainly as injection providers. There is a need for a multi-faceted response encompassing education and reform of financial incentives to reduce the use of unnecessary treatment.

Review of antimicrobial resistance control strategies: low impact of prospective audit with feedback on bacterial antibiotic resistance within hospital settings.

BACKGROUND: Antimicrobial stewardship constitutes an essential element of any concerted effort to tackle bacterial resistance, a rising public health threat both in community as well as hospital settings. The term comprises variable strategies which aim to optimise prescribing practices through either antibiotic restrictions or prospective audits of prescriptions with subsequent feedback to clinicians. Although highly debated, the actual effects of the latter on the antimicrobial susceptibility patterns of hospital flora are uncertain. The present study aims to review and evaluate the literature concerning the impact of persuasive stewardship strategies on antimicrobial resistance within hospitals. MATERIALS AND METHODS: A literature review covering the period to 1st April 2020 was conducted using the PubMed/Medline, Embase, Global Health and CINAHL Plus databases. RESULTS: Fifteen studies were retrieved, including twelve simple before-and-after, and three interrupted time-series studies. Audit frequency and compliance rates varied broadly. The rationale of treatment optimisation is not clear in most cases. Overall, surveillance of sentinel microorganisms through antibiograms indicates ambiguous results, with uncertainty as to whether the few successes are due to a causal effect, random incidence fluctuations, or confounding. The most informative approach targeted solely fluoroquinolones, reporting improvements in relevant Pseudomonas susceptibilities and MRSA, but without sufficient data on other effects of the strategy to assess its overall utility in clinical practice. CONCLUSION: Higher standard research is needed to address the actual effects of persuasive stewardship strategies on antimicrobial susceptibility patterns. At present, they seem inadequate to play a decisive role in bacterial resistance control within hospitals.

Organised crime and the efforts to combat it: a concern for public health.

This paper considers the public health impacts of the income-generating activities of organised crime. These range from the traditional vice activities of running prostitution and supplying narcotics, to the newer growth areas of human trafficking in its various forms, from international supply of young people and children as sex workers through deceit, coercion or purchase from family, through to smuggling of migrants, forced labour and the theft of human tissues for transplant, and the sale of fake medications, foodstuffs and beverages, cigarettes and other counterfeit manufactures. It looks at the effect of globalisation on integrating supply chains from poorly-regulated and impoverished source regions through to their distant markets, often via disparate groups of organised criminals who have linked across their traditional territories for mutual benefit and enhanced profit, with both traditional and newly-created linkages between production, distribution and retail functions of cooperating criminal networks from different cultures. It discusses the interactions between criminals and the structures of the state which enable illegal and socially undesirable activities to proceed on a massive scale through corruption and subversion of regulatory mechanisms. It argues that conventional approaches to tackling organised crime often have deleterious consequences for public health, and calls for an evidence-based approach with a focus on outcomes rather than ideology.

Matching supply and demand for blood in Guizhou province, China: an unresolved challenge.

BACKGROUND: Problems with blood supply in China in the 1990s stimulated measures to achieve 100% voluntary donation but supply remains inadequate to meet demand. STUDY DESIGN AND METHODS: Review of official policies, supplemented with observation of practice and interviews with key informants (potential and actual donors and health workers) in Guizhou province in Southern China. RESULTS: Interviewees perceived the transfusion system as a mutual social contract. However, some individuals were unwilling to donate because of concerns about health risks, the idea of transferring blood between people, wastage or profits being made from blood. Inappropriate incentives, including cash, were used to encourage donation. Recent reforms have increased confidence in donation and transfusion safety although concerns persist about misuse. There is a need to reduce unnecessary use of blood and its products. CONCLUSION: China still relies heavily on blood supplies obtained through quota, purchase or use of incentives. There is scope to expand voluntary donation further. However, as a priority it will be necessary to reduce overuse.

Factors influencing antibiotic prescribing in China: an exploratory analysis.

OBJECTIVES: China has very high rates of antibiotic resistance and a health care system that provides strong incentives for over-prescribing. This paper describes the findings of a qualitative study in a province of southern China that seeks to assess knowledge, attitudes, and practices in relation to the use of antibiotics. METHODS: Semi-structured interviews with patients and health workers at provincial, county, township, and village level. Interviews used four probes (common cold, cough, mild diarrhoea and tiredness) where antibiotics were not indicated, supplemented by questions on knowledge, attitudes, and practices. These data were supplemented by two focus groups, with medical students and pharmacists, and discussions with participants at a national conference on antibiotic use. RESULTS: Coughs and diarrhoea are almost universally treated with antibiotics, while the cold is normally treated with antivirals instead or as well. Many physicians are aware that the cold is usually self-limiting but believe that they can speed recovery and that they are responding to patient expectations. Most physicians and many patients are aware of the phenomenon of antibiotic resistance, although it is often seen as a property acquired by the patient and not the micro-organism. Physicians face financial incentives to prescribe, with profit splitting with pharmaceutical suppliers. Sales profits form a major part of a hospital's income. National guidance on use of antibiotics is fragmentary and incomplete. CONCLUSION: The misuse of antibiotics poses considerable risks. Effective action will require a multi-faceted strategy including education, based on an understanding of existing beliefs, the replacement of perverse incentives with those promoting best practice, and investment in improved surveillance. Much of this will require action at national level.

Not Up for Discussion: Applying Lukes' Power Model to the Study of Health System Corruption Comment on "We Need to Talk About Corruption in Health Systems".

This companion paper suggests the potential benefits of applying Steven Lukes' dimensions of power model to the study of corruption in health systems. Lukes' model sets out three "faces of power" classified by their influence on political discourse, resulting in overt, covert and latent discussion of issues depending on the degree of their alignment with the agenda of dominant power interests. His concept that differential access to public discourse varies according to this alignment implies the potential for identifying more serious forms of corruption by the mismatch between their practical importance and the amount of open debate addressing them. These two variables are in practice inversely related, and do not, as might be expected, correlate, with more important topics receiving more public attention. Lukes' model would predict and can explain such inversion of public priorities, which tells us that observed suppression of public debate might efficiently direct the interest of researchers and the efforts of those seeking to further the public good on to the key issues needing discussion and resolution. The commentary goes on to examine whether the most serious and dangerous forms of corruption might therefore also be the most invisible, and suggests that whistleblower reports should be considered a key data source for research into high-level corruption in health systems, including redirection of policy decisions away from those which are in the public interest.
