Developing checklists to prevent diagnostic error in Emergency Room settings.

BACKGROUND: Checklists have been shown to improve performance of complex, error-prone processes. To develop a checklist with potential to reduce the likelihood of diagnostic error for patients presenting to the Emergency Room (ER) with undiagnosed conditions. METHODS: Participants included 15 staff ER physicians working in two large academic centers. A rapid cycle design and evaluation process was used to develop a general checklist for high-risk situations vulnerable to diagnostic error. Physicians used the general checklists and a set of symptom-specific checklists for a period of 2 months. We conducted a mixed methods evaluation that included interviews regarding user perceptions and quantitative assessment of resource utilization before and after checklist use. RESULTS: A general checklist was developed iteratively by obtaining feedback from users and subject matter experts, and was trialed along with a set of specific checklists in the ER. Both the general and the symptom-specific checklists were judged to be helpful, with a slight preference for using symptom-specific lists. Checklist use commonly prompted consideration of additional diagnostic possibilities, changed the working diagnosis in approximately 10% of cases, and anecdotally was thought to be helpful in avoiding diagnostic errors. Checklist use was prompted by a variety of different factors, not just diagnostic uncertainty. None of the physicians used the checklists in collaboration with the patient, despite being encouraged to do so. Checklist use did not prompt large changes in test ordering or consultation. CONCLUSIONS: In the ER setting, checklists for diagnosis are helpful in considering additional diagnostic possibilities, thus having potential to prevent diagnostic errors. Inconsistent usage and using the checklists privately, instead of with the patient, are factors that may detract from obtaining maximum benefit. Further research is needed to optimize checklists for use in the ER, determine how to increase usage, to evaluate the impact of checklist utilization on error rates and patient outcomes, to determine how checklist usage affects test ordering and consultation, and to compare checklists generally with other approaches to reduce diagnostic error.

Advancing infection control in dental care settings: factors associated with dentists' implementation of guidelines from the Centers for Disease Control and Prevention.

BACKGROUND AND OVERVIEW: The authors set out to identify factors associated with implementation by U.S. dentists of four practices first recommended in the Centers for Disease Control and Prevention's Guidelines for Infection Control in Dental Health-Care Settings-2003. METHODS: In 2008, the authors surveyed a stratified random sample of 6,825 U.S. dentists. The response rate was 49 percent. The authors gathered data regarding dentists' demographic and practice characteristics, attitudes toward infection control, sources of instruction regarding the guidelines and knowledge about the need to use sterile water for surgical procedures. Then they assessed the impact of those factors on the implementation of four recommendations: having an infection control coordinator, maintaining dental unit water quality, documenting percutaneous injuries and using safer medical devices, such as safer syringes and scalpels. The authors conducted bivariate analyses and proportional odds modeling. RESULTS: Responding dentists in 34 percent of practices had implemented none or one of the four recommendations, 40 percent had implemented two of the recommendations and 26 percent had implemented three or four of the recommendations. The likelihood of implementation was higher among dentists who acknowledged the importance of infection control, had practiced dentistry for less than 30 years, had received more continuing dental education credits in infection control, correctly identified more surgical procedures that require the use of sterile water, worked in larger practices and had at least three sources of instruction regarding the guidelines. Dentists with practices in the South Atlantic, Middle Atlantic or East South Central U.S. Census divisions were less likely to have complied. CONCLUSIONS: Implementation of the four recommendations varied among U.S. dentists. Strategies targeted at raising awareness of the importance of infection control, increasing continuing education requirements and developing multiple modes of instruction may increase implementation of current and future Centers for Disease Control and Prevention guidelines.

Cognitive interventions to reduce diagnostic error: a narrative review.

BACKGROUND: Errors in clinical reasoning occur in most cases in which the diagnosis is missed, delayed or wrong. The goal of this review was to identify interventions that might reduce the likelihood of these cognitive errors. DESIGN: We searched PubMed and other medical and non-medical databases and identified additional literature through references from the initial data set and suggestions from subject matter experts. Articles were included if they either suggested a possible intervention or formally evaluated an intervention and excluded if they focused solely on improving diagnostic tests or provider satisfaction. RESULTS: We identified 141 articles for full review, 42 reporting tested interventions to reduce the likelihood of cognitive errors, 100 containing suggestions, and one article with both suggested and tested interventions. Articles were classified into three categories: (1) Interventions to improve knowledge and experience, such as simulation-based training, improved feedback and education focused on a single disease; (2) Interventions to improve clinical reasoning and decision-making skills, such as reflective practice and active metacognitive review; and (3) Interventions that provide cognitive 'help' that included use of electronic records and integrated decision support, informaticians and facilitating access to information, second opinions and specialists. CONCLUSIONS: We identified a wide range of possible approaches to reduce cognitive errors in diagnosis. Not all the suggestions have been tested, and of those that have, the evaluations typically involved trainees in artificial settings, making it difficult to extrapolate the results to actual practice. Future progress in this area will require methodological refinements in outcome evaluation and rigorously evaluating interventions already suggested, many of which are well conceptualised and widely endorsed.

System-related interventions to reduce diagnostic errors: a narrative review.

BACKGROUND: Diagnostic errors (missed, delayed or wrong diagnosis) have recently gained attention and are associated with significant preventable morbidity and mortality. The authors reviewed the recent literature and identified interventions that address system-related factors that contribute directly to diagnostic errors. METHODS: The authors conducted a comprehensive search using multiple search strategies. First, they performed a PubMed search to identify articles exclusively related to diagnostic error or delay published in English between 2000 and 2009. They then sought papers from references in the initial dataset, searches of additional databases, and subject matter experts. Articles were included if they formally evaluated an intervention to prevent or reduce diagnostic error; however, papers were also included if interventions were suggested and not tested to inform the state of the science on the subject. Interventions were characterised according to the step in the diagnostic process they targeted: patient-provider encounter; performance and interpretation of diagnostic tests; follow-up and tracking of diagnostic information; subspecialty and referral-related issues; and patient-specific care-seeking and adherence processes. RESULTS: 43 articles were identified for full review, of which six reported tested interventions and 37 contained suggestions for possible interventions. Empirical studies, although somewhat positive, were non-experimental or quasi-experimental and included a small number of clinicians or healthcare sites. Outcome measures in general were underdeveloped and varied markedly among studies, depending on the setting or step in the diagnostic process. CONCLUSIONS: Despite a number of suggested interventions in the literature, few empirical studies in the past decade have tested interventions to reduce diagnostic errors. Advancing the science of diagnostic error prevention will require more robust study designs and rigorous definitions of diagnostic processes and outcomes to measure intervention effects.

Evaluating efforts to optimize TeamSTEPPS implementation in surgical and pediatric intensive care units.

BACKGROUND: An evidence-based teamwork system, Team-STEPPS, was implemented in an academic medical center's pediatric and surgical ICUs. METHODS: A multidisciplinary change team of unit- and department-based leaders was formed to champion the initiative; develop a customized action plan for implementation; train frontline staff; and identify process, team outcome, and clinical outcome objectives for the intervention. The evaluation consisted of interviews with key staff, teamwork observations, staff surveys, and clinical outcome data. RESULTS: All PICU, SICU, and respiratory therapy staff received TeamSTEPPS training. Staff reported improved experience of teamwork posttraining and evaluated the implementation as effective. Observed team performance significantly improved for all core areas of competency at 1 month postimplementation and remained significantly improved for most of the core areas of competency at 6 and 12 months postimplementation. Survey data indicated improvements in staff perceptions of teamwork and communication openness in both units. From pre- to posttraining, the average time for placing patients on extracorporeal membrane oxygenation (ECMO) decreased significantly. The average duration of adult surgery rapid response team events was 33% longer at postimplementation versus pre-implementation. The rate of nosocomial infections at postimplementation was below the upper control limit for seven out of eight months in both the PICU and the SICU. CONCLUSIONS: The implementation of a customized 2.5-hour version of the TeamSTEPPS training program in two areas--the PICU and SICU--that had demonstrated successful ability to innovate suggests that the training was successful.

Physicians' views on public reporting of hospital quality data.

This article describes physicians' responses to patient questions and physicians' views about public reports on hospital quality. Interviews with 56 office-based physicians in seven states/regions used hypothetical scenarios of patients questioning referrals based on public reports of hospital quality. Responses were analyzed using an iterative coding process to develop categories and themes from data. Four themes describe physicians' responses to patients: (a) rely on existing physician-patient relationships, (b) acknowledge and consider patient perspectives, (c) take actions to follow up on patient concerns, and (d) provide patients' perspectives on quality reports. Three themes summarize responses to hospital quality reports: perceived lack of methodological rigor, content considerations in reports, and attitudes/experience regarding reports. Findings suggest that physicians take seriously patients' questions about hospital-quality reports and consider changing referral recommendations based on their concerns and/or preferences. Results underscore the importance of efforts by report developers and physician outreach/education to address physicians' methodological concerns.

Disparities in immunizations among elderly Medicare beneficiaries, 2000 to 2002.

BACKGROUND: Research reveals that influenza and pneumococcal immunization rates among blacks, Asians, and Hispanics significantly trail those of whites. This 2003 study examines recent trends and disparities for influenza and pneumococcal immunizations among elderly, non-institutionalized Medicare beneficiaries. METHODS: National samples of approximately 179,000 Medicare fee-for-service beneficiaries were surveyed by mail and telephone each year from 2000 to 2002. Outcomes include self-reported influenza immunization in the previous year and receipt of a pneumococcal immunization ever. RESULTS: Influenza immunization dipped in 2001 (69%) and almost rebounded to its 2000 level (73%) in 2002 (72%). Very substantial racial and ethnic disparities in the receipt of this preventive service exist between non-Hispanic blacks and Hispanics relative to non-Hispanic whites. Pneumococcal immunization increased by 2% annually (61%, 63%, and 65%) for the same years. However, very substantial racial and ethnic disparities in the receipt of this preventive service also exist between non-Hispanic blacks, Asians/Pacific Islanders, and Hispanics relative to non-Hispanic whites. CONCLUSIONS: Younger, healthier, elderly persons must be encouraged to receive these immunizations to achieve the 2010 goal of 90% immunization. To reach that goal with no disparities, special efforts will be needed to target racial/ethnic minorities.
