Burden of endemic health-care-associated infection in developing countries: systematic review and meta-analysis

BACKGROUND Health-care-associated infection is the most frequent result of unsafe patient care worldwide, but few data are available from the developing world. We aimed to assess the epidemiology of endemic health-care-associated infection in developing countries. METHODS We searched electronic databases and reference lists of relevant papers for articles published 1995-2008. Studies containing full or partial data from developing countries related to infection prevalence or incidence-including overall health-care-associated infection and major infection sites, and their microbiological cause-were selected. We classified studies as low-quality or high-quality according to predefined criteria. Data were pooled for analysis. FINDINGS Of 271 selected articles, 220 were included in the final analysis. Limited data were retrieved from some regions and many countries were not represented. 118 (54%) studies were low quality. In general, infection frequencies reported in high-quality studies were greater than those from low-quality studies. Prevalence of health-care-associated infection (pooled prevalence in high-quality studies, 15·5 per 100 patients [95% CI 12·6-18·9]) was much higher than proportions reported from Europe and the USA. Pooled overall health-care-associated infection density in adult intensive-care units was 47·9 per 1000 patient-days (95% CI 36·7-59·1), at least three times as high as densities reported from the USA. Surgical-site infection was the leading infection in hospitals (pooled cumulative incidence 5·6 per 100 surgical procedures), strikingly higher than proportions recorded in developed countries. Gram-negative bacilli represented the most common nosocomial isolates. Apart from meticillin resistance, noted in 158 of 290 (54%) Staphylococcus aureus isolates (in eight studies), very few articles reported antimicrobial resistance. INTERPRETATION The burden of health-care-associated infection in developing countries is high. Our findings indicate a need to improve surveillance and infection-control practices.

Patient participation: current knowledge and applicability to patient safety.

Patient participation is increasingly recognized as a key component in the redesign of health care processes and is advocated as a means to improve patient safety. The concept has been successfully applied to various areas of patient care, such as decision making and the management of chronic diseases. We review the origins of patient participation, discuss the published evidence on its efficacy, and summarize the factors influencing its implementation. Patient-related factors, such as acceptance of the new patient role, lack of medical knowledge, lack of confidence, comorbidity, and various sociodemographic parameters, all affect willingness to participate in the health care process. Among health care workers, the acceptance and promotion of patient participation are influenced by other issues, including the desire to maintain control, lack of time, personal beliefs, type of illness, and training in patient-caregiver relationships. Social status, specialty, ethnic origin, and the stakes involved also influence patient and health care worker acceptance. The London Declaration, endorsed by the World Health Organization World Alliance for Patient Safety, calls for a greater role for patients to improve the safety of health care worldwide. Patient participation in hand hygiene promotion among staff to prevent health care-associated infection is discussed as an illustrative example. A conceptual model including key factors that influence participation and invite patients to contribute to error prevention is proposed. Further research is essential to establish key determinants for the success of patient participation in reducing medical errors and in improving patient safety.

The Top Patient Safety Strategies That Can Be Encouraged for Adoption Now

Over the past 12 years, since the publication of the Institute of Medicines report, “To Err is Human: Building a Safer Health System,” improving patient safety has been the focus of considerable public and professional interest. Although such efforts required changes in policies; education; workforce; and health care financing, organization, and delivery, the most important gap has arguably been in research. Specifically, to improve patient safety we needed to identify hazards, determine how to measure them accurately, and identify solutions that work to reduce patient harm. A 2001 report commissioned by the Agency for Healthcare Research and Quality, “Making Health Care Safer: A Critical Analysis of Patient Safety Practices” (1), helped identify some early evidence-based safety practices, but it also highlighted an enormous gap between what was known and what needed to be known.

Advancing the science of patient safety

Despite a decades worth of effort, patient safety has improved slowly, in part because of the limited evidence base for the development and widespread dissemination of successful patient safety practices. The Agency for Healthcare Research and Quality sponsored an international group of experts in patient safety and evaluation methods to develop criteria to improve the design, evaluation, and reporting of practice research in patient safety. This article reports the findings and recommendations of this group, which include greater use of theory and logic models, more detailed descriptions of interventions and their implementation, enhanced explanation of desired and unintended outcomes, and better description and measurement of context and of how context influences interventions. Using these criteria and measuring and reporting contexts will improve the science of patient safety.

Clean Care is Safer Care: a worldwide priority

At any time more than 1.4 million people worldwide are afflicted by infections acquired in hospitals. Between 5% and 10% of patients admitted to modern hospitals in developed countries acquire one or more infections; 15–40% of those admitted to critical care are affected. The risk is two to 20 times higher in developing than in developed countries. The burden of disease outside hospital is practically unknown owing to the absence of surveillance. Importantly no health-care setting no hospital no country in the world can claim to have solved the problem. On Oct 13 2005 the WHO World Alliance for Patient Safety launches the first biennial Global Patient Safety Challenge “Clean Care is Safer Care” which targets infection associated with health care and will cover 2005–06. But why has this area been targeted when so many other diseases are vying for investment-priority status and public attention? (excerpt)

Paediatric mortality related to pandemic influenza A H1N1 infection in England: an observational population-based study

BACKGROUND Young people (aged 0-18 years) have been disproportionately affected by pandemic influenza A H1N1 infection. We aimed to analyse paediatric mortality to inform clinical and public health policies for future influenza seasons and pandemics. METHODS All paediatric deaths related to pandemic influenza A H1N1 infection from June 26, 2009, to March 22, 2010 in England were identified through daily reporting systems and cross-checking of records and were validated by confirmation of influenza infection by laboratory results or death certificates. Clinicians responsible for each individual child provided detailed information about past medical history, presentation, and clinical course of the acute illness. Case estimates of influenza A H1N1 were obtained from the Health Protection Agency. The primary outcome measures were population mortality rates and case-fatality rates. FINDINGS 70 paediatric deaths related to pandemic influenza A H1N1 were reported. Childhood mortality rate was 6 per million population. The rate was highest for children aged less than 1 year. Mortality rates were higher for Bangladeshi children (47 deaths per million population [95% CI 17-103]) and Pakistani children (36 deaths per million population [18-64]) than for white British children (4 deaths per million [3-6]). 15 (21%) children who died were previously healthy; 45 (64%) had severe pre-existing disorders. The highest age-standardised mortality rate for a pre-existing disorder was for chronic neurological disease (1536 per million population). 19 (27%) deaths occurred before inpatient admission. Children in this subgroup were significantly more likely to have been healthy or had only mild pre-existing disorders than those who died after admission (p=0·0109). Overall, 45 (64%) children had received oseltamivir: seven within 48 h of symptom onset. INTERPRETATION Vaccination priority should be for children at increased risk of severe illness or death from influenza. This group might include those with specified pre-existing disorders and those in some ethnic minority groups. Early pre-hospital supportive and therapeutic care is also important.

The WHO patient safety curriculum guide for medical schools

Background The urgent need for patient safety education for healthcare students has been recognised by many accreditation bodies, but to date there has been sporadic attention to undergraduate/graduate medical programmes. Medical students themselves have identified quality and safety of care as an important area of instruction; as future doctors and healthcare leaders, they must be prepared to practise safe healthcare. Medical education has yet to fully embrace patient safety concepts and principles into existing medical curricula. Universities are continuing to produce graduate doctors lacking in the patient safety knowledge, skills and behaviours thought necessary to deliver safe care. A significant challenge is that patient safety is still a relatively new concept and area of study; thus, many medical educators are unfamiliar with the literature and unsure how to integrate patient safety learning into existing curriculum. Design To address this gap and provide a foothold for medical schools all around the world, the WHOs World Alliance for Patient Safety sponsored the development of a patient safety curriculum guide for medical students. The WHO Patient Safety Curriculum Guide for Medical Schools adopts a ‘one-stop-shop’ approach in that it includes a teachers manual providing a step-by-step guide for teachers new to patient safety learning as well as a comprehensive curriculum on the main patient safety areas. This paper establishes the need for patient safety education of medical students, describes the development of the WHO Patient Safety Curriculum Guide for Medical Schools and outlines the content of the Guide.

Developed-developing country partnerships: Benefits to developed countries?

Developing countries can generate effective solutions for today’s global health challenges. This paper reviews relevant literature to construct the case for international cooperation, and in particular, developed-developing country partnerships. Standard database and web-based searches were conducted for publications in English between 1990 and 2010. Studies containing full or partial data relating to international cooperation between developed and developing countries were retained for further analysis. Of 227 articles retained through initial screening, 65 were included in the final analysis. The results were two-fold: some articles pointed to intangible benefits accrued by developed country partners, but the majority of information pointed to developing country innovations that can potentially inform health systems in developed countries. This information spanned all six WHO health system components. Ten key health areas where developed countries have the most to learn from the developing world were identified and include, rural health service delivery; skills substitution; decentralisation of management; creative problem-solving; education in communicable disease control; innovation in mobile phone use; low technology simulation training; local product manufacture; health financing; and social entrepreneurship. While there are no guarantees that innovations from developing country experiences can effectively transfer to developed countries, combined developed-developing country learning processes can potentially generate effective solutions for global health systems. However, the global pool of knowledge in this area is virgin and further work needs to be undertaken to advance understanding of health innovation diffusion. Even more urgently, a standardized method for reporting partnership benefits is needed—this is perhaps the single most immediate need in planning for, and realizing, the full potential of international cooperation between developed and developing countries.

Religion and culture: Potential undercurrents influencing hand hygiene promotion in health care

Background Health care–associated infections affect hundreds of millions of patients worldwide each year. The World Health Organizations (WHO) First Global Patient Safety Challenge, “Clean Care is Safer Care,” is tackling this major patient safety problem, with the promotion of hand hygiene in health care as the projects cornerstone. WHO Guidelines on Hand Hygiene in Healthcare have been prepared by a large group of international experts and are currently in a pilot-test phase to assess feasibility and acceptability in different health care settings worldwide. Methods An extensive literature search was conducted and experts and religious authorities were consulted to investigate religiocultural factors that may potentially influence hand hygiene promotion, offer possible solutions, and suggest areas for future research. Results Religious faith and culture can strongly influence hand hygiene behavior in health care workers and potentially affect compliance with best practices. Interesting data were retrieved on specific indications for hand cleansing according to the 7 main religions worldwide, interpretation of hand gestures, the concept of “visibly dirty” hands, and the use of alcohol-based hand rubs and prohibition of alcohol use by some religions. Conclusions The impact of religious faith and cultural specificities must be taken into consideration when implementing a multimodal strategy to promote hand hygiene on a global scale.
