Learning curve analysis of thoracic endovascular aortic repair in relation to credentialing guidelines.
(33/115)
OBJECTIVE: Recently, practice guideline documents have recommended the completion of different levels of interventional experience and 5 or 10 thoracic endovascular aortic cases prior to surgeon credentialing. This study's purpose was to determine whether these requirements are valid by reviewing three surgeons' learning curves with thoracic aortic endovascular repairs. METHODS: Between 1998 and 2006, 67 patients underwent emergent or elective endovascular repair of thoracic aortic pathologies by one of three vascular surgeons with extensive experience with catheter manipulation and abdominal aortic endografts. Following standard retrospective review, each surgeon's learning curve was analyzed using the cumulative sum failure method with a target success rate of 95% derived from the literature. The main outcome variable was primary technical success. RESULTS: These 67 patients presented with several pathologies including elective (n = 31) and ruptured (n = 11) thoracic aortic aneurysms, acute dissections or aortic ulcers (n = 10), and acute blunt thoracic aortic trauma (n = 15). The mean age was 65 (range: 20 to 90) and the early (30 day) mortality rate was 19.4% in urgent cases (n = 36) and 0% in elective cases (n = 31). Paraplegia occurred in two patients (3%). Primary technical success was achieved in 62 cases (92.5%) and did not differ between surgeons (92.6%, 91.3%, 94.1%, respectively; P = .9). Each surgeon's cases were plotted sequentially and the resulting learning curves were similar. Although acceptable outcomes were obtained throughout the study period, improved results, compared with the target success rate, were not achieved until each surgeon treated 5 to 10 patients. CONCLUSION: This study supports the case volume requirements of the Society for Vascular Surgery credentialing guidelines, which also requires extensive catheter and guidewire experience. With this background in catheter manipulation and endovascular abdominal aortic repair, surgeons can achieve optimal outcomes with thoracic aortic lesions following 5 to 10 cases. (+info)
The National Board of Public Health Examiners: credentialing public health graduates.
(34/115)
The National Board of Public Health Examiners (NBPHE, the Board) is the result of many years of intense discussion about the importance of credentialing within the public health community. The Board is scheduled to begin credentialing graduates of programs and schools of public health accredited by the Council on Education for Public Health (CEPH) in 2008. Among the many activities currently underway to improve public health practice, the Board views credentialing as one pathway to heighten recognition of public health professionals and increase the overall effectiveness of public health practice. The process underway includes developing, preparing, administering, and evaluating a voluntary certification examination that tests whether graduates of CEPH-accredited schools and programs have mastered the core knowledge and skills relevant to contemporary public health practice. This credentialing initiative is occurring at a time of heightened interest in public health education, and an anticipated rapid turnover in the public health workforce. It is fully anticipated that active discussion about the credentialing process will continue as the Board considers the many aspects of this professional transition. The Board wishes to encourage these discussions and welcomes input on any aspects relating to implementation of the credentialing process. (+info)
Comparing credentialing requirements of substance abuse treatment staff by funding source.
(35/115)
Studies have found that clinicians with higher education and/or attainment of national certification have a more favorable outlook regarding the adoption of evidence-based practices. However, staff hiring decisions may be based on a multitude of factors, including available resources and demands stemming from different funders. Using a mixed-methods case study approach with 34 agencies within one state, we assessed administrators' perspectives of the most important funding source, views on clinical hiring practices, and current staffing. We found that funding source predicted views and actual staff level of credentialing and education. Those agencies citing a criminal justice entity as the most important funder had the lowest requirements for credentialing and education. As the substance abuse treatment delivery system evolves and expands, we must ensure that vulnerable groups have access to more highly--rather than less--skilled workers to assess and facilitate recovery.

Assessing dual-role staff-interpreter linguistic competency in an integrated healthcare system.
(36/115)
BACKGROUND: Interpreter services for medical care increase physician-patient communication and safety, yet a "formal certification" process to demonstrate interpreter competence does not exist. Testing and training is left to individual health care facilities nationwide. Bilingual staff are often used to interpret, without any assessment of their skills. Assessing interpreters' linguistic competence and setting standards for testing is a priority. OBJECTIVE: To assess dual-role staff interpreter linguistic competence in an integrated health care system to determine skill qualification to work as medical interpreters. DESIGN: Dual-role staff interpreters voluntarily completed a linguistic competency assessment using a test developed by a language school to measure comprehension, completeness, and vocabulary through written and oral assessment in English and the second language. Pass levels were predetermined by school as not passing, basic (limited ability to read, write, and speak English and the second language) and medical interpreter level. Five staff-interpreter focus groups discussed experiences as interpreters and with language test. RESULTS: A total of 840 dual-role staff interpreters were tested for Spanish (75%), Chinese (12%), and Russian (5%) language competence. Most dual-role interpreters serve as administrative assistants (39%), medical assistants (27%), and clinical staff (17%). Two percent did not pass, 21% passed at basic level, 77% passed at medical interpreter level. Staff that passed at the basic level was prone to interpretation errors, including omissions and word confusion. Focus groups revealed acceptance of exam process and feelings of increased validation in interpreter role. CONCLUSIONS: We found that about 1 in 5 dual-role staff interpreters at a large health care organization had insufficient bilingual skills to serve as interpreters in a medical encounter. Health care organizations that depend on dual-role staff interpreters should consider assessing staff English and second language skills. (+info)
Language access services for Latinos with limited English proficiency: lessons learned from Hablamos Juntos.
(37/115)
BACKGROUND: The Robert Wood Johnson Foundation funded Hablamos Juntos (HJ), a $10-million multiyear demonstration to improve access to health care for Latinos with limited English proficiency and to explore cost-effective ways for health care organizations to provide language access services. HABLAMOS JUNTOS: In this manuscript, the authors draw on their experiences in evaluating HJ, provide brief descriptions of innovative interventions, estimate operating costs, and synthesize lessons learned about implementation. A number of barriers and facilitators are documented. CONCLUSION: The experience of HJ grantees provides guidance for organizations contemplating similar efforts. In particular, it highlights the need for health care organizations to involve physicians in the design and adoption of language services. (+info)
The legal framework for language access in healthcare settings: Title VI and beyond.
(38/115)
Over the past few decades, the number and diversity of limited English speakers in the USA has burgeoned. With this increased diversity has come increased pressure--including new legal requirements--on healthcare systems and clinicians to ensure equal treatment of limited English speakers. Healthcare providers are often unclear about their legal obligations to provide language services. In this article, we describe the federal mandates for language rights in health care, provide a broad overview of existing state laws and describe recent legal developments in addressing language barriers. We conclude with an analysis of key policy initiatives that would substantively improve health care for LEP patients. (+info)
Dose specification and quality assurance of radiation therapy oncology group protocol 95-17; a cooperative group study of iridium-192 breast implants as sole therapy.
(39/115)
PURPOSE: The Radiation Therapy Oncology Group (RTOG) protocol 95-17 was a Phase I/II trial to evaluate multicatheter brachytherapy as the sole method of adjuvant breast radiotherapy for Stage I/II breast carcinoma after breast-conserving surgery. Low- or high-dose-rate sources were allowed. Dose prescription and treatment evaluation were based on recommendations in the International Commission on Radiation Units and Measurements (ICRU), Report 58 and included the parameters mean central dose (MCD), average peripheral dose, dose homogeneity index (DHI), and the dimensions of the low- and high-dose regions. METHODS AND MATERIALS: Three levels of quality assurance were implemented: (1) credentialing of institutions was required before entering patients into the study; (2) rapid review of each treatment plan was conducted before treatment; and (3) retrospective review was performed by the Radiological Physics Center in conjunction with the study chairman and RTOG dosimetry staff. RESULTS: Credentialing focused on the accuracy of dose calculation algorithm and compliance with protocol guidelines. Rapid review was designed to identify and correct deviations from the protocol before treatment. The retrospective review involved recalculation of dosimetry parameters and review of dose distributions to evaluate the treatment. Specifying both central and peripheral doses resulted in uniform dose distributions, with a mean dose homogeneity index of 0.83 +/- 0.06. CONCLUSIONS: Vigorous quality assurance resulted in a high-quality study with few deviations; only 4 of 100 patients were judged as representing minor variations from protocol, and no patient was judged as representing major deviation. This study should be considered a model for quality assurance of future trials. (+info)
The emergence of clinical practice guidelines.
(40/115)
Clinical practice guidelines are now ubiquitous. This article describes the emergence of such guidelines in a way that differs from the two dominant explanations, one focusing on administrative cost-cutting and the other on the need to protect collective professional autonomy. Instead, this article argues that the spread of guidelines represents a new regulation of medical care resulting from a confluence of circumstances that mobilized many different groups. Although the regulation of quality has traditionally been based on the standardization of professional credentials, since the 1960s it has intensified and been supplemented by efforts to standardize the use of medical procedures. This shift is related to the spread of standardization within medicine and especially in research, public health, and large bureaucratic health care organizations. (+info)
