Practice based education to improve delivery systems for prevention in primary care: randomised trial

Abstract Objective To examine the effectiveness of an intervention that combined continuing medical education with process improvement methods to implement “office systems” to improve the delivery of preventive care to children. Design Randomised trial in primary care practices. Setting Private paediatric and family practices in two areas of North Carolina. Participants Random sample of 44 practices allocated to intervention and control groups. Intervention Practice based continuing medical education in which project staff coached practice staff in reviewing performance and identifying, testing, and implementing new care processes (such as chart screening) to improve delivery of preventive care. Main outcome measure Change over time in the proportion of children aged 24-30 months who received age appropriate care for four preventive services (immunisations, and screening for tuberculosis, anaemia, and lead). Results The proportion of children per practice with age appropriate delivery of all four preventive services changed, after a one year period of implementation, from 7% to 34% in intervention practices and from 9% to 10% in control practices. After adjustment for baseline differences in the groups, the change in the prevalence of all four services between the beginning and the end of the study was 4.6-fold greater (95% confidence interval 1.6 to 13.2) in intervention practices. Thirty months after baseline, the proportion of children who were up to date with preventive services was higher in intervention than in control practices; results for screening for tuberculosis (54% v 32%), lead (68% v 30%), and anaemia (79% v 71%) were statistically significant (P < 0.05). Conclusion Continuing education combined with process improvement methods is effective in increasing rates of delivery of preventive care to children.

Otitis media, hearing loss, and language learning: Controversies and current research

ABSTRACT. This article reviews research on the possible linkage of otitis media with effusion (OME) to childrens hearing and development, identifies gaps, and directions for research, and discusses implications for healthcare practices. About half of children with an episode of OME experience a mild hearing loss while about 5-10% of children have moderate hearing loss. Recent prospective and randomized clinical trials suggest none to very small negative associations of OME to childrens later language development. Based on both retrospective and prospective longitudinal studies, associations between OME and perceiving speech in noise and tasks that require equal binaural hearing have been reported but have not been adequately studied with regard to functional outcomes. Thus, on average, for typically developing children, OME may not be a substantial risk factor for later speech and language development or academic achievement. However, these conclusions should be interpreted cautiously, since most of these studies used OME rather than hearing loss as the independent variable (although hearing loss rather than OME is hypothesized to affect language development) and many studies did not control for important confounding variables such as socioeconomic status (SES).

Improving clinical breast examination training in a medical school: a randomized controlled trial

To evaluate a new program for teaching clinical breast examination, a class of 156 second-year medical students were randomized into an experimental group (practice and feedback on silicone breast models and women volunteers) and a control group (lecture only). During a simulated practical clinical examination routinely conducted at the end of the second year, the experimental group students used more suggested palpation techniques during a patient examination (4.6 vs 2.0; p<0.0001) and found more simulated lumps in a silicone model (4.7 vs 4.4; p<0.05). Practice with immediate feedback is more effective than lecture alone in teaching clinical breast examination.

Health literacy and quality: focus on chronic illness care and patient safety.

Despite a heightened focus on improving quality, recent studies have suggested that children only receive half of the indicated preventive, acute, or chronic care. Two major areas in need of improvement are chronic illness care and prevention of medical errors. Recently, health literacy has been identified as an important and potentially ameliorable factor for improving quality of care. Studies of adults have documented that lower health literacy is independently associated with poorer understanding of prescriptions and other medical information and worse chronic disease knowledge, self-management behaviors, and clinical outcomes. There is also growing evidence to suggest that health literacy is important in pediatric safety and chronic illness care. Adult studies have suggested that addressing literacy can lead to improved patient knowledge, behaviors, and outcomes. Early studies in the field of pediatrics have shown similar promise. There are significant opportunities to evaluate and demonstrate the importance of health literacy in improving pediatric quality of care. Efforts to address health literacy should be made to apply the 6 Institute of Medicine aims for quality-care that is safe, effective, patient centered, timely, efficient, and equitable. Efforts should also be made to consider the distinct nature of pediatric care and address the “4 Ds” unique to child health: the developmental change of children over time; dependency on parents or adults; differential epidemiology of child health; and the different demographic patterns of children and their families.

Anatomy of a patient safety event: a pediatric patient safety taxonomy

Background: Idiosyncratic terminology and frameworks in the study of patient safety have been tolerated but are increasingly problematic. Agreement on standard language and frameworks is needed for optimal improvement and dissemination of knowledge about patient safety. Methods: Patient safety events were assessed using critical incident analysis, a method used to classify risks that has been more recently applied to medicine. Clinician interviews and clinician reports to a web based reporting system were used for analysis of hospital based and ambulatory care events, respectively. Events were classified independently by three investigators. Results: A pediatric patient safety taxonomy, relevant to both hospital based and ambulatory pediatric care, was developed from the analysis of 122 hospital based and 144 ambulatory care events. It is composed of four main categories: (1) problem type; (2) domain of medicine; (3) contributing factors in the patient (child-specific), environment (latent conditions) and care providers (human factors); and (4) outcome or result of the event and level of harm. A classification of preventive mechanisms was also developed. Inter-rater reliability of classifications ranged from 72% to 86% for sub-categories of the taxonomy. Conclusions: This patient safety taxonomy reflects the nature of events that occur in both pediatric hospital based and ambulatory care settings. It is flexible in its construction, permits analysis to begin at any point, and depicts the relationships and interactions of elements of an event.

Organizational Characteristics and Preventive Service Delivery in Private Practices: A Peek Inside the “Black Box” of Private Practices Caring for Children

Objective. Although privately owned practices provide the majority of primary care for children, little is known about the organizational characteristics of these practices or how these characteristics affect the quality of care for children. The purpose of this study was to describe selected organizational characteristics and preventive service delivery features that might affect the quality of primary care for children in private practices. Methods. A cross-sectional study of 44 private pediatric and family medicine practices in 2 regions of North Carolina was performed. Preventive service performance was assessed through chart abstraction for 60 randomly selected children between 24 and 30 months of age, for evaluation of immunizations and anemia, tuberculosis, and lead screening delivery by 2 years of age. Organizational characteristics were determined through surveys of all physicians and staff members. We used descriptive statistics and scatter plots to describe variations in organizational characteristics and preventive services. Results. Overall, practices demonstrated low levels of preventive service performance, with substantial variation among practices. Only 39% of children received 3 of the 4 recommended preventive services measured (practice range: 2–88%). Few practices demonstrated evidence of a systematic approach to prevention. For example, only 12 (27%) of the 44 practices used >1 of 5 recommended preventive service delivery strategies. Furthermore, practices varied greatly with respect to many of the measured organizational characteristics, which were consistent with organizational stress in some cases. For example, turnover of clinicians and staff members was remarkably high, with practices losing an average of 27% of their clinicians every 4 years (range: 0–170%) and 39% of their office staff members every 2 years (range: 0–170%). Conclusions. Private practices caring for children in North Carolina demonstrated low overall performance for the 4 recommended preventive services examined, with large variations among practices. Few practices had evidence of comprehensive systems for prevention. There was also evidence of substantial variation in many organizational characteristics. Some organizational characteristics were at levels that might impede delivery of high-quality primary care for children. These findings suggest a growing need for research that examines the impact of organizational characteristics on the quality of care in private practices.

Quality Measures for the Care of Children With Otitis Media With Effusion

BACKGROUND: Current national efforts provide an opportunity to integrate performance measures into clinical practice and improve outcomes for children. OBJECTIVE: The goal of this study was to explore issues in developing and testing measures of care for children with otitis media with effusion (OME). METHODS: We assessed compliance with diagnostic, evaluation, and treatment measures for OME adapted from preliminary work of the Physician Consortium for Performance Improvement, using chart data in a convenience sample of practices from 2 primary care networks (Cincinnati Pediatric Research Group and the American Academy of Pediatrics Quality Improvement Innovation Network). Children aged 2 months to 12 years with at least 1 visit with a specified OME code during a 1-year period were included. RESULTS: Of 23 practices, 4 could not locate eligible visits. Nineteen practices submitted 378 abstractions (range: 3–37 per practice) with 15 identifying <30 eligible visits. Performance on diagnosis (33%) and hearing evaluation (29%) measures was low but high on measures of appropriate medication use (97% decongestant/antihistamine, 87% antibiotics, and 95% corticosteroids). Thirty-five percent of records documented antibiotic use concurrent with OME; only 16% of the 94 cases that cited reason for prescribing were appropriate. Using methods that consider appropriate clinical action, a more accurate rate for appropriate use of antibiotics was 68%. CONCLUSIONS: Coding, case finding, and evaluating appropriateness of treatment are some of the issues that will need to be considered to assess the care of children with OME. This study emphasizes the importance of testing proposed quality of care measures in “real-world” settings.

Screening for hypercholesterolemia in children: The missing links

A useful screening program depends on a serious and prevalent disease, an acceptable, valid, and reliable test, and an efficacious and cost-effective intervention in the population of interest. Although coronary heart disease is still the leading cause of death in the United States, screening childrens lipids to detect those at high risk is problematic. Long-term studies starting in childhood have so far revealed less than optimal accuracy of a childs serum cholesterol to predict an adult level. Information regarding reliability of lipid measurements that could improve accuracy is sparse. No interventions have proven beneficial compared to current practice, and the costs of an extensive screening program, including misclassification, side effects, labeling, and treatment, are likely to be high. Until more information regarding these factors is available, widespread screening of serum cholesterol in children cannot be recommended.

Using a network organisational architecture to support the development of Learning Healthcare Systems

The US National Academy of Sciences has called for the development of a Learning Healthcare System in which patients and clinicians work together to choose care, based on best evidence, and to drive discovery as a natural outgrowth of every clinical encounter to ensure innovation, quality and value at the point of care. However, the vision of a Learning Healthcare System has remained largely aspirational. Over the last 13 years, researchers, clinicians and families, with support from our paediatric medical centre, have designed, developed and implemented a network organisational model to achieve the Learning Healthcare System vision. The network framework aligns participants around a common goal of improving health outcomes, transparency of outcome measures and a flexible and adaptive collaborative learning system. Team collaboration is promoted by using standardised processes, protocols and policies, including communication policies, data sharing, privacy protection and regulatory compliance. Learning methods include collaborative quality improvement using a modified Breakthrough Series approach and statistical process control methods. Participants observe their own results and learn from the experience of others. A common repository (a ‘commons’) is used to share resources that are created by participants. Standardised technology approaches reduce the burden of data entry, facilitate care and result in data useful for research and learning. We describe how this organisational framework has been replicated in four conditions, resulting in substantial improvements in outcomes, at scale across a variety of conditions.
