Are Language Barriers Associated With Serious Medical Events in Hospitalized Pediatric Patients

Objective. Language barriers may lead to medical errors by impeding patient-provider communication. The objective of this study was to determine whether hospitalized pediatric patients whose families have language barriers are more likely to incur serious medical errors than patients whose families do not have language barriers. Methods. A case-control study was conducted in a large, academic, regional childrens hospital in the Pacific Northwest. Case patients (n = 97) included all hospitalizations of patients who were younger than 21 years and had a reported serious medical event from January 1, 1998, to December 31, 2003. Control patients (n = 475) were chosen from hospitalizations without a reported serious medical event and were matched with case patients on age, admitting service, admission to intensive care, and date of admission. The main exposure was a language barrier defined by self- or provider-reported need for an interpreter. Serious medical events were defined as events that led to unintended or potentially adverse outcomes identified by the hospitals quality improvement staff. Results. Fourteen (14.4%) of the case patients and 53 (11.2%) of the control patients were assigned an interpreter during their hospitalization. Overall, we found no increased risk for serious medical events in patients and families who requested an interpreter compared with patients and families who did not request an interpreter (odds ratio: 1.36; 95% confidence interval: 0.73–2.55). Spanish-speaking patients who requested an interpreter comprised 11 (11.3%) of the case patients and 26 (5.5%) of the control patients. This subgroup had a twofold increased risk for serious medical events compared with patients who did not request an interpreter (odds ratio: 2.26; 95% confidence interval: 1.06–4.81). Conclusions. Spanish-speaking patients whose families have a language barrier seem to have a significantly increased risk for serious medical events during pediatric hospitalization compared with patients whose families do not have a language barrier.

Variation in inpatient diagnostic testing and management of bronchiolitis

Objectives. We know little about the variation in diagnosis and management of bronchiolitis. The objectives of this study were (1) to document variations in treatment and diagnostic approaches, lengths of stay (LOSs), and readmission rates and (2) to determine which potentially modifiable process of care measures are associated with longer LOSs and antibiotic usage. Methods. We used the Pediatric Health Information System, which includes demographic, diagnostic, and detailed patient-level data on 30 large childrens hospitals. We examined infants who were younger than 1 year and hospitalized for bronchiolitis (October 2001–September 2003). Multivariate analysis of variance was used to determine whether the variance in the outcomes was hospital related after controlling for other covariates. Linear regression was used to model predictors of increased LOS. Logistic regression was used to model antibiotic usage. Analyses were stratified by age group (<3 months and 3–11 months). Results. A total of 17397 patients were included in the analysis. The mean LOS was 2.97 days; 72% of patients received chest radiographs, 45% received antibiotics, and 25% received systemic steroids. The mean LOS varied considerably across hospitals (range: 2.40–3.90 days), and hospital remained a significant contributor to LOS variation after controlling for our covariates. Variations in the use of diagnostic tests and medications as well as readmission rates also existed and also remained significant after controlling for covariates. The factors associated with the greatest increases in LOS in the regression analyses included higher severity scores and use of antibiotics, bronchodilators, and corticosteroids. The strongest predictors of antibiotic use in the logistic regression analyses were higher severity scores and receipt of a blood or cerebrospinal fluid culture. Receiving a chest radiograph was a significant predictor of antibiotic use in older but not younger infants. Conclusions. Considerable, unexplained variation exists in the inpatient management of bronchiolitis. The development of national guidelines and controlled trials of new therapies and different management approaches are indicated.

Social Marketing as a Strategy to Increase Immunization Rates

Today in the United States, outbreaks of vaccine-preventable disease are often traced to susceptible children whose parents have claimed an exemption from school or child care immunization regulations. The origins of this immunization hesitancy and resistance have roots in the decline of the threat of vaccine-preventable disease coupled with an increase in concerns about the adverse effects of vaccines, the emergence of mass media and the Internet, and the intrinsic limitations of modern medicine. Appeals to emotion have drowned out thoughtful discussion in public forums, and overall, public trust in immunizations has declined. We present an often overlooked behavior change strategy-social marketing-as a way to improve immunization rates by addressing the important roots of immunization hesitancy and effectively engaging emotions. As an example, we provide a synopsis of a social marketing campaign that is currently in development in Washington state and that is aimed at increasing timely immunizations in children from birth to age 24 months.

Teaching professionalism to residents.

The need to teach professionalism during residency has been affirmed by the Accreditation Council for Graduate Medical Education, which will require documentation of education and evaluation of professionalism by 2007. Recently the American Academy of Pediatrics has proposed the following components of professionalism be taught and measured: honesty/integrity, reliability/responsibility, respect for others, compassion/empathy, self-improvement, self-awareness/knowledge of limits, communication/collaboration, and altruism/advocacy. The authors describe a curriculum for introducing the above principles of professionalism into a pediatrics residency that could serve as a model for other programs. The curriculum is taught at an annual five-day retreat for interns, with 11 mandatory sessions devoted to addressing key professionalism issues. The authors also explain how the retreat is evaluated and how the retreats topics are revisited during the residency, and discuss general issues of teaching and evaluating professionalism.

Vaccines and immunization

Publisher Summary Immunization has fundamentally altered the global infectious disease ecology. Powerful pathogens, once so prevalent that they toppled empires and laid waste to communities and cultures, are now only a distant memory. Smallpox today only exists in laboratories, and its danger now comes from its perceived threat if employed as a biological weapon. Polio persists in only a few corners of the world just 50 years after development of a vaccine. The indigenous transmission of measles has been drastically reduced throughout the Western Hemisphere. Congenital rubella has been eliminated from the United States and, in much of the world, entire organizations and institutions no longer exist as a result of successful disease elimination through immunization. In developed nations, orthopedic and rehabilitation hospitals have evolved into acute care childrens hospitals or have gone out of business altogether, and charitable institutions that were once solely dedicated to fighting infectious diseases like polio have now branched out into other efforts, such as the prevention of birth defects. For many today, deadly infectious diseases are a historic relic without a personal memory or current face. However, the emergence and spread of HIV and its resulting devastation in the latter part of the last century, and the recent emergence of a virulent new strain of avian influenza, coupled with the recognition that the deadly 1918 influenza pandemic, was due to an avian influenza strain that adapted to human-to-human transmission, has made clear mankinds continued vulnerability to epidemic infectious disease.

Vaccine safety--vaccine benefits: science and the public's perception.

The development of cowpox vaccination by Jenner led to the development of immunology as a scientific discipline. The subsequent eradication of smallpox and the remarkable effects of other vaccines are among the most important contributions of biomedical science to human health. Today, the need for new vaccines has never been greater. However, in developed countries, the publics fear of vaccine-preventable diseases has waned, and awareness of potential adverse effects has increased, which is threatening vaccine acceptance. To further the control of disease by vaccination, we must develop safe and effective new vaccines to combat infectious diseases, and address the publics concerns.

Vaccine knowledge and practices of primary care providers of exempt vs. vaccinated children

Objectives: Compare vaccine knowledge, attitudes, and practices of primary care providers for fully vaccinated children and children who are exempt from school immunization requirements. Methods: We conducted a mailed survey of parent-identified primary care providers from four states to measure perceived risks and benefits of vaccination and other key immunization beliefs. Frequencies of responses were stratified by type of provider, identified by exempt versus vaccinated children. Logistic regression was used to calculate odds ratios for responses by provider type. Results: 551 surveys were completed (84.3% response rate). Providers for exempt children had similar attitudes to providers for non-exempt children. However, there were statistically significant increased concerns among providers for exempt children regarding vaccine safety and lack of perceived individual and community benefits for vaccines compared to other providers. Conclusions: The great majority of providers for exempt children had similar attitudes about vaccine safety, effectiveness, and benefits as providers of non-exempt children. Although providers for exempt children were more likely to believe that multiple vaccines weaken a child’s immune system and were concerned about vaccine safety and less likely to consider vaccines were beneficial, a substantial proportion of providers of both exempt and vaccinated children have concerns about vaccine safety and believe that CDC underestimates the frequency of vaccine side effects. Effective continuing education of providers about the risks and benefits of immunization and including in vaccine recommendations more information on pre and post licensing vaccine safety evaluations may overcome some of these perceptions.

Association of vaccine-related attitudes and beliefs between parents and health care providers.

OBJECTIVES Health care providers influence parental vaccination decisions. Over 90% of parents report receiving vaccine information from their childs health care provider. The majority of parents of vaccinated children and children exempt from school immunization requirements report their childs primary provider is a good source for vaccine information. The role of health care providers in influencing parents who refuse vaccines has not been fully explored. The objective of the study was to determine the association between vaccine-related attitudes and beliefs of health care providers and parents. METHODS We surveyed parents and primary care providers of vaccinated and unvaccinated school age children in four states in 2002-2003 and 2005. We measured key immunization beliefs including perceived risks and benefits of vaccination. Odds ratios for associations between parental and provider responses were calculated using logistic regression. RESULTS Surveys were completed by 1367 parents (56.1% response rate) and 551 providers (84.3% response rate). Parents with high confidence in vaccine safety were more likely to have providers with similar beliefs, however viewpoints regarding disease susceptibility and severity and vaccine efficacy were not associated. Parents whose providers believed that children get more immunizations than are good for them had 4.6 higher odds of holding that same belief compared to parents whose providers did not have that belief. CONCLUSIONS The beliefs of childrens health care providers and parents, including those regarding vaccine safety, are similar. Provider beliefs may contribute to parental decisions to accept, delay or forgo vaccinations. Parents may selectively choose providers who have similar beliefs to their own.

Controversies in Vaccine Mandates

Policies that mandate immunization have always been controversial. The controversies take different forms in different contexts. For routine childhood immunizations, many parents have fears about both short- and long-term side effects. Parental worries change as the rate of vaccination in the community changes. When most children are vaccinated, parents worry more about side effects than they do about disease. Because of these worries, immunization rates go down. As immunization rates go down, disease rates go up, and parents worry less about side effects of vaccination and more about the complications of the diseases. Immunization rates then go up. For teenagers, controversies arise about the criteria that should guide policies that mandate, rather than merely recommend and encourage, certain immunizations. In particular, policy makers have questioned whether immunizations for human papillomavirus, or other diseases that are not contagious, should be required. For healthcare workers, debates have focused on the strength of institutional mandates. For years, experts have recommended that all healthcare workers be immunized against influenza. Immunizations for other infections including pertussis, measles, mumps, and hepatitis are encouraged but few hospitals have mandated such immunizations-instead, they rely on incentives and education. Pandemics present a different set of problems as people demand vaccines that are in short supply. These issues erupt into controversy on a regular basis. Physicians and policy makers must respond both in their individual practices and as advisory experts to national and state agencies. The articles in this volume will discuss the evolution of national immunization programs in these various settings. We will critically examine the role of vaccine mandates. We will discuss ways that practitioners and public health officials should deal with vaccine refusal. We will contrast responses of the population as a whole, within the healthcare setting, and in the setting of pandemic influenza.

A critique of criteria for evaluating vaccines for inclusion in mandatory school immunization programs.

Several new vaccines for children and young adults have been introduced recently and now appear on the Advisory Committee on Immunization Practices’ recommended childhood and adolescent immunization schedule (meningococcal, rotavirus, human papillomavirus). As new vaccines are introduced, states face complex decisions regarding which vaccines to fund and which vaccines to require for school or child care entry. This complexity is evidenced by the current debate surrounding the human papillomavirus vaccine. We present a critique to the approach and criteria for evaluating vaccines for inclusion in mandatory school immunization programs that have been adopted by the Washington State Board of Health by illustrating how these criteria might be applied to the human papillomavirus vaccine. We conclude that these 9 criteria can help ensure a deliberate and informed approach to important public policy decisions, but we argue that several clarifications of the review process are needed along with the addition of a 10th criterion that ensures that a new vaccine mandate relates in some manner to increasing safety in the school environment.
