Management of benign paroxysmal positional vertigo with the canalith repositioning maneuver in the emergency department setting

Vertigo is a common clinical manifestation in the emergency department (ED). It is important for physicians to determine if the peripheral cause of vertigo is benign paroxysmal positional vertigo (BPPV), a disorder accounting for 20% of all vertigo cases. However, the Dix-Hallpike test—the standard for BPPV diagnosis—is not common in the ED setting. If no central origin of the vertigo is determined, patients in the ED are typically treated with benzodiazepine, antihistamine, or anticholinergic agents. Studies have shown that these pharmaceutical treatment options may not be the best for patients with BPPV.

The authors describe a case of a 38-year-old woman who presented to the ED with complaints of severe, sudden-onset vertigo. The patient's BPPV was diagnosed by means of a Dix-Hallpike test and the patient was acutely treated in the ED with physical therapy using the canalith repositioning maneuver.

A multi-institutional quality improvement initiative to transform education for chronic illness care in resident continuity practices

BACKGROUND: There is a gap between the need for patient-centered, evidence-based primary care for the large burden of chronic illness in the US, and the training of resident physicians to provide that care.

OBJECTIVE: To improve training for residents who provide chronic illness care in teaching practice settings.

DESIGN: US teaching hospitals were invited to participate in one of two 18-month Breakthrough Series Collaboratives-either a national Collaborative, or a subsequent California Collaborative-to implement the Chronic Care Model (CCM) and related curriculum changes in resident practices. Most practices focused on patients with diabetes mellitus. Educational redesign strategies with related performance measures were developed for curricular innovations anchored in the CCM. In addition, three clinical measures-HbA1c <7%, LDL <100 mg/dL, and blood pressure <or=130/80-and three process measures-retinal and foot examinations, and patient self-management goals-were tracked.

PARTICIPANTS: Fifty-seven teams from 37 self-selected teaching hospitals committed to implement the CCM in resident continuity practices; 41 teams focusing on diabetes improvement participated over the entire duration of one of the Collaboratives.

INTERVENTIONS: Teaching-practice teams-faculty, residents and staff-participated in Collaboratives by attending monthly calls and regular 2-day face-to-face meetings with the other teams. The national Collaborative faculty led calls and meetings. Each team used rapid cycle quality improvement (PDSA cycles) to implement the CCM and curricular changes. Teams reported education and clinical performance measures monthly.

RESULTS: Practices underwent extensive redesign to establish CCM elements. Education measures tracked substantial development of CCM-related learning. The clinical and process measures improved, however inconsistently, during the Collaboratives.

CONCLUSIONS: These initiatives suggest that systematic practice redesign for implementing the CCM along with linked educational approaches are achievable in resident continuity practices. Improvement of clinical outcomes in such practices is daunting but achievable.

Using the Teamlet Model to improve chronic care in an academic primary care practice

BACKGROUND: Team care can improve management of chronic conditions, but implementing a team approach in an academic primary care clinic presents unique challenges.

OBJECTIVES: To implement and evaluate the Teamlet Model, which uses health coaches working with primary care physicians to improve care for patients with diabetes and/or hypertension in an academic practice.

DESIGN: Process and outcome measures were compared before and during the intervention in patients seen with the Teamlet Model and in a comparison patient group.

PARTICIPANTS: First year family medicine residents, medical assistants, health workers, and adult patients with either type 2 diabetes or hypertension in a large public health clinic.

INTERVENTION: Health coaches, in coordination with resident primary care physicians, met with patients before and after clinic visits and called patients between visits.

MEASUREMENTS: Measurement of body mass index, assessment of smoking status, and formulation of a self-management plan prior to and during the intervention period for patients in the Teamlet Model group. Testing for LDL and HbA1C and the proportion of patients at goal for blood pressure, LDL, and HbA1C in the Teamlet Model and comparison groups in the year prior to and during implementation.

RESULTS: Teamlet patients showed improvement in all measures, though improvement was significant only for smoking, BMI, and self-management plan documentation and testing for LDL (p = 0.02), with a trend towards significance for LDL at goal (p = 0.07). Teamlet patients showed a greater, but non-significant, increase in the proportion of patients tested for HbA1C and proportion reaching goal for blood pressure, HgbA1C, and LDL compared to the comparison group patients. The difference for blood pressure was marginally significant (p = 0.06). In contrast, patients in the comparison group were significantly more likely to have had testing for LDL (P = 0.001).

CONCLUSIONS: The Teamlet Model may improve chronic care in academic primary care practices.

Implementation of a chronic illness model for diabetes care in a family medicine residency program

INTRODUCTION: While the Chronic Care Model (CCM) has been shown to improve the care of patients with chronic illnesses, primary care physicians have been unprepared in its use, and residencies have encountered challenges in introducing it into the academic environment.

AIM: Our residency program has implemented a diabetes management program modeled on the CCM to evaluate its impact on health outcomes of diabetic patients and educational outcomes of residents.

SETTING: University-affiliated, community-based family medicine residency program.

PROGRAM DESCRIPTION: Six residents, two faculty clinicians, and clinic staff formed a diabetes management team. We redesigned the outpatient experience for diabetic patients by incorporating elements of the CCM: multidisciplinary team care through planned and group visits; creation of a diabetes registry; use of guidelines-based flow sheets; and incorporation of self-management goal-setting. Residents received extensive instruction in diabetes management, quality improvement, and patient self-management.

PROGRAM EVALUATION: We achieved overall improvement in all metabolic and process measures for patients, with the percentage achieving HbA1c, LDL, and BP goals simultaneously increasing from 5.7% to 17.1%. Educational outcomes for residents, as measured by compliance with review of provider performance reports and self-management goal-setting with patients, also significantly improved.

DISCUSSION: Through a learning collaborative experience, residency programs can successfully incorporate chronic care training for residents while addressing gaps in care for patients with diabetes.

Linking a motivational interviewing curriculum to the chronic care model

BACKGROUND: Unhealthy lifestyle choices frequently cause or worsen chronic diseases. Many internal medicine residents are inadequately trained to provide effective health behavior counseling, in part, due to prioritization of acute care in the traditional model of medical education and to other systemic barriers to teaching psychosocial aspects of patient care.

AIM: To address this gap in training, we developed and piloted a curriculum for a Primary Care Internal Medicine residency program that links a practical form of motivational interviewing (MI) training to the self-management support (SMS) component of the chronic care model.

PARTICIPANTS AND SETTING: All 30 primary care residents at Alameda County Medical Center were trained in the curriculum since it was initiated in 2007 during the California Academic Chronic Care Collaborative.

PROGRAM DESCRIPTION: Residents participated in three modules during which the chronic care model was introduced and motivational interviewing skills were linked to the model's self-management support component. This training was then reinforced in the clinical setting. Case-based interactive instruction, teaching videotapes, group role-plays, faculty demonstration, and observation of resident-patient interactions in the clinical setting were used to teach the curriculum.

PROGRAM ASSESSMENT: A preliminary, qualitative assessment of this curriculum was done from a program standpoint and from the perspective of the learners. Residents reported increased sense of confidence when approaching patients about health behavior change. Faculty directly observed residents during clinical encounters using MI and SMS skills to work more collaboratively with patients and to improve patient readiness for self-management goal setting.

CONCLUSION: A curriculum that links motivational interviewing skills to the chronic care model's self-management support component and is reinforced in the clinical setting is feasible to develop and implement. This curriculum may improve residents' confidence with health behavior counseling and with preparing patients to become active participants in management of their chronic conditions.

The role for clinician educators in implementing healthcare improvement

Clinician educators-who work at the intersection of patient care and resident education-are well positioned to respond to calls for better, safer patient care and resident education. Explicit lessons that address implementing health care improvement and associated residency training came out of the Academic Chronic Care Collaboratives and include the importance of: (1) redesigning the clinical practice as a core component of the residency curriculum; (2) exploiting the efficiencies of the practice team; (3) replacing "faculty development" with "everyone's a learner;" (4) linking faculty across learning communities to build expertise; and (5) using rigorous methodology to design and evaluate interventions for practice redesign.

There has been progress in addressing three thorny academic faculty issues-professional satisfaction, promotion and publication. For example, consensus criteria have been proposed for both faculty promotion as well as the institutional settings that nurture academic health care improvement careers, and the SQUIRE Publication Guidelines have been developed as a general framework for scholarly improvement publications. Extensive curricular resources exist for developing the expert faculty cadre. Curricula from representative training programs include quantitative and qualitative research methods, statistical methodologies appropriate for measuring systems change, organizational culture, management, leadership and scholarly writing for the improvement literature.

Clinician educators-particularly those in general internal medicine-bear the principal responsibility for both patient care and resident training in academic departments of internal medicine. The intersection of these activities presents a unique opportunity for their playing a central role in implementing health care improvement and associated residency training. However, this role in academic settings will require an unambiguous development strategy both for faculty and their institutions.

Resident education in 2011: three key challenges on the road ahead

Two important changes in the past decade have altered the landscape of graduate medical education (GME) in the U.S. The national restrictions on trainee duty hours mandated by the Accreditation Council for Graduate Medical Education (ACGME) were the most visible and generated much controversy. Equally important is the ACGME Outcome Project, which mandates competency-based training. Both of these changes have unique implications for surgery trainees, who traditionally spent long hours caring for patients in the hospital, and who must be assessed in 2 broad domains: their medical care of pre- and postoperative patients, and their technical skill with procedures in and out of the operating room.

This article summarizes 3 key challenges that lie ahead for surgical educators. First, the changes in duty hours in the past 7 years are summarized, and the conversation about added restrictions planned for July 2011 is reviewed. Next, the current state of the assessment of competency among surgical trainees is reviewed, with an outline of the challenges that need to be overcome to achieve widespread, competency-based training in surgery. Finally, the article summarizes the problems caused by increased reliance on handoffs among trainees as they compensate for decreased time in the hospital, and suggests changes that need to be made to improve safety and efficiency, including how to use handoffs as part of our educational evaluation of residents.

Effect of 16-hour duty periods on patient care and resident education

OBJECTIVE: To measure the effect of duty periods no longer than 16 hours on patient care and resident education.

PATIENTS AND METHODS: As part of our Educational Innovations Project, we piloted a novel resident schedule for an inpatient service that eliminated shifts longer than 16 hours without increased staffing or decreased patient admissions on 2 gastroenterology services from August 29 to November 27, 2009. Patient care variables were obtained through medical record review. Resident well-being and educational variables were collected by weekly surveys, end of rotation evaluations, and an electronic card-swipe system.

RESULTS: Patient care metrics, including 30-day mortality, 30-day readmission rate, and length of stay, were unchanged for the 196 patient care episodes in the 5-week intervention month compared with the 274 episodes in the 8 weeks of control months. However, residents felt less prepared to manage cross-cover of patients (P = .006). There was a nonsignificant trend toward decreased perception of quality of education and balance of personal and professional life during the intervention month. Residents reported working fewer weekly hours overall during the intervention (64.3 vs 68.9 hours; P = .40), but they had significantly more episodes with fewer than 10 hours off between shifts (24 vs 2 episodes; P = .004).

CONCLUSION: Inpatient hospital services can be staffed with residents working shifts less than 16 hours without additional residents. However, cross-cover of care, quality of education, and time off between shifts may be adversely affected.

Duty hour recommendations and implications for meeting the ACGME core competencies

OBJECTIVE: To describe the views of residency program directors regarding the effect of the 2010 duty hour recommendations on the 6 core competencies of graduate medical education.

METHODS: US residency program directors in internal medicine, pediatrics, and general surgery were e-mailed a survey from July 8 through July 20, 2010, after the 2010 Accreditation Council for Graduate Medical Education (ACGME) duty hour recommendations were published. Directors were asked to rate the implications of the new recommendations for the 6 ACGME core competencies as well as for continuity of inpatient care and resident fatigue.

RESULTS: Of 719 eligible program directors, 464 (65%) responded. Most program directors believe that the new ACGME recommendations will decrease residents' continuity with hospitalized patients (404/464 [87%]) and will not change (303/464 [65%]) or will increase (26/464 [6%]) resident fatigue. Additionally, most program directors (249-363/464 [53%-78%]) believe that the new duty hour restrictions will decrease residents' ability to develop competency in 5 of the 6 core areas. Surgery directors were more likely than internal medicine directors to believe that the ACGME recommendations will decrease residents' competency in patient care (odds ratio [OR], 3.9; 95% confidence interval [CI], 2.5-6.3), medical knowledge (OR, 1.9; 95% CI, 1.2-3.2), practice-based learning and improvement (OR, 2.7; 95% CI, 1.7-4.4), interpersonal and communication skills (OR, 1.9; 95% CI, 1.2-3.0), and professionalism (OR, 2.5; 95% CI, 1.5-4.0).

CONCLUSION: Residency program directors' reactions to ACGME duty hour recommendations demonstrate a marked degree of concern about educating a competent generation of future physicians in the face of increasing duty hour standards and regulation.

The influence of longitudinal mentoring on medical student selection of primary care residencies

Background: The number of students selecting careers in primary care has declined by 41% in the last decade, resulting in anticipated shortages.

Methods: First-year medical students interested in primary care were paired with primary care mentors. Mentors were trained, and mentors and students participated in focus groups at the end of each academic year. Quantitative and qualitative results are presented.

Results: Students who remained in the mentoring program matched to primary care programs at 87.5% in the first year and 78.9% in the second year, compared to overall discipline-specific match rates of 55.8% and 35.9% respectively. Students reported a better understanding of primary care and appreciated a relationship with a mentor.

Conclusions: A longitudinal mentoring program can effectively support student interest in primary care if it focuses on the needs of the students and is supportive of the mentors.

Description of web-enhanced virtual character simulation system to standardize patient hand-offs

INTRODUCTION: The 80-h work week has increased discontinuity of patient care resulting in reports of increased medication errors and preventable adverse events. Graduate medical programs are addressing these shortcomings in a number of ways.

METHODS: We have developed a computer simulation platform called the Virtual People Factory (VPF), which allows us to capture and simulate the dialogue between a real user and a virtual character. We have converted the system to reflect a physician in the process of "checking-out" a patient to a covering physician. The responses are tracked and matched to educator-defined information termed "discoveries." Our proof of concept represented a typical post-operative patient with tachycardia. The system is web enabled.

RESULTS: So far, 26 resident users at two institutions have completed the module. The critical discovery of tachycardia was identified by 62% of users. Residents spend 85% of the time asking intraoperative, postoperative, and past medical history questions. The system improves over time such that there is a near-doubling of questions that yield appropriate answers between users 13 and 22. Users who identified the virtual patient's underlying tachycardia expressed more concern and were more likely to order further testing for the patient in a post-module questionnaire (P = 0.13 and 0.08, respectively, NS).

CONCLUSIONS: The VPF system can capture unique details about the hand-off interchange. The system improves with sequential users such that better matching of questions and answers occurs within the initial 25 users allowing rapid development of new modules. A catalog of hand-off modules could be easily developed. Wide-scale web-based deployment was uncomplicated. Identification of the critical findings appropriately translated to user concern for the patient though our series was too small to reach significance. Performance metrics based on the identification of critical discoveries could be used to assess readiness of the user to carry off a successful hand-off.

Comparison of surgical operative experience of trainees and practicing vascular surgeons

INTRODUCTION: The Vascular Surgery Board (VSB) of the American Board of Surgery sought to answer the following questions: what is the scope of contemporary vascular surgery practice? Do current vascular surgery residents obtain training that is appropriate for their future career expectations and for successful Board certification? How effectively do practicing vascular surgeons incorporate emerging technologies and procedures into practice?

METHODS: We analyzed the operative logs submitted to the VSB by recent vascular surgery residents applying for the Vascular Surgery Qualifying Examination (QE; 2006-2009) or by practicing vascular surgeons applying for the Vascular Surgery Recertification Examination (RE; 1995-2009). The relationship between reported operative experience and performance of the QE and RE was examined.

RESULTS: There has been a threefold increase in the mean number of primary cases reported by both RE and QE applicants over the past 15 years and the increase in case volume has been driven largely by an increase in the number of endovascular procedures. Endovascular procedures have been broadly incorporated into the practice of most vascular surgeons applying for recertification. The number of major open surgical cases reported by recent QE applicants has remained unchanged over the period of observation. For QE applicants, the number of endovascular aneurysm repairs (EVARs) has reached a plateau at approximately 50 cases, whereas the mean number of open infrarenal aneurysm repairs has decreased for both QE and RE applicants, reflecting national trends favoring EVAR. There was a significant association between case volume and performance on the QE but not on the RE.

CONCLUSION: Over the past 15 years, there has been a significant increase in the total number of operative cases reported to the VSB by both QE and RE applicants. Contrary to popular belief, the volume of major open vascular surgery reported by recent vascular surgery residents has remained relatively stable since 1994. Over the same time period, endovascular procedures have been rapidly incorporated into clinical practice by the majority of vascular surgeons applying for recertification by the VSB. Current vascular surgery residents receive a rich operative experience in both open and endovascular procedures that is reflective of contemporary practice.
