The Clinical Health Economics System Simulation (CHESS): a teaching tool for systems- and practice-based learning.

Academic medical centers face barriers to training physicians in systems- and practice-based learning competencies needed to function in the changing health care environment. To address these problems, at the University of Virginia School of Medicine the authors developed the Clinical Health Economics System Simulation (CHESS), a computerized team-based quasi-competitive simulator to teach the principles and practical application of health economics. CHESS simulates treatment costs to patients and society as well as physician reimbursement. It is scenario based with residents grouped into three teams, each team playing CHESS using differing (fee-for-service or capitated) reimbursement models. Teams view scenarios and select from two or three treatment options that are medically justifiable yet have different potential cost implications. CHESS displays physician reimbursement and patient and societal costs for each scenario as well as costs and income summarized across all scenarios extrapolated to a physician's entire patient panel. The learners are asked to explain these findings and may change treatment options and other variables such as panel size and case mix to conduct sensitivity analyses in real time. Evaluations completed in 2003 by 68 (94%) CHESS resident and faculty participants at 19 U.S. residency programs preferred CHESS to a traditional lecture-and-discussion format to learn about medical decision making, physician reimbursement, patient costs, and societal costs. Ninety-eight percent reported increased knowledge of health economics after viewing the simulation. CHESS demonstrates the potential of computer simulation to teach health economics and other key elements of practice- and systems-based competencies.

Free clinics: a national survey.

OBJECTIVES: To describe the scope and value of services provided by free clinics across the United States. METHODS: Mail survey of directors of free clinics registered in the Free Clinic Directory of the Free Clinic Foundation of America, November 2001, concerning the calendar year 2001. RESULTS: Eighty two percent (281/355) of clinics responded. Seventy five percent of clinics described their target population as the "uninsured" and 23% as "low income". Fifty five percent had income based eligibility criteria of 200% Federal poverty level or less. Clinics provided a mean of 5,989 patient visits/year and 11,202 prescriptions/year to 2,311 unique patients. 61.8% of patients were female, 80.4% between ages 19 to 64, 55.1% white, 21.8% black, and 18.7% Hispanic. Clinics were open 29.7 hours/week, 4.1 days/week, and 32.9% had a licensed pharmacy. The mean annual budget was $458,028 and clinics were staffed by 156.7 volunteers and 6.9 paid employees per clinic. CONCLUSIONS: Free clinics have become an established part of the safety net for the uninsured. The differences among the clinics are striking, supporting the conclusion that a variety of approaches to the care of the underserved can be used. However, despite their efforts, the responding free clinics manage to provide care to only 650,000 of the nation's 41 million uninsured.

Determinants of physician use of an ambulatory prescription expert system.

PURPOSE: To determine whether physician experience with and attitude towards computers is associated with adoption of a voluntary ambulatory prescription writing expert system. METHODS: A prescription expert system was implemented in an academic internal medicine residency training clinic and physician utilization was tracked electronically. A physician attitude and behavior survey (response rate=89%) was conducted six months after implementation. RESULTS: There was wide variability in system adoption and degree of usage, though 72% of physicians reported predominant usage (> or =50% of prescriptions) of the expert system six months after implementation. Self-reported and measured technology usage were strongly correlated (r=0.70, p<0.0001). Variation in use was strongly associated with physician attitude toward issues of system efficiency and effect on quality, but not with prior computer experience, level of training, or satisfaction with their primary care practice. Non-adopters felt that electronic prescribing was more time consuming and also more likely to believe that their patients preferred hand-written prescriptions. CONCLUSION: A voluntary electronic prescription system was readily adopted by a majority of physicians who believed it would have a positive impact on the quality and efficiency of care. However, dissatisfaction with system capabilities among both adopters and non-adopters suggests the importance of user education and expectation management following system selection.

The association between diabetes metabolic control and drug adherence in an indigent population.

OBJECTIVE: Studies of the association between diabetes metabolic control and adherence to drug therapy have yielded conflicting results. Because low socioeconomic and minority populations have poorer diabetes outcomes and greater barriers to adherence, we examined the relationship between adherence and diabetes metabolic control in a large indigent population. RESEARCH DESIGN AND METHODS: The study population consisted of patients receiving medical care from a university-based internal medicine clinic serving a low-income population in rural central Virginia. The sample comprised 810 patients with type 2 diabetes who received oral diabetes medications from the clinic pharmacy and had at least one HbA(1c) determination during the study period. Multiple linear regression was used to examine the association of HbA(1c) level as well as change in HbA(1c) level with medication adherence, demographic, and clinical characteristics. RESULTS: Better metabolic control was independently associated with greater medication adherence, increasing age, white (versus African-American) race, and lower intensity of drug therapy. For each 10% increment in drug adherence, HbA(1c) decreased by 0.16% (P < 0.0001). Controlling for other demographic and clinical variables, the mean HbA(1c) of African-Americans was 0.29% higher than that of whites (P = 0.04). Additionally, the intensity of diabetes drug therapy for African-Americans was lower, as was their measured adherence to it. There was no association between metabolic control and gender, income, encounter frequency, frequency of HbA(1c) testing, or continuity of care. CONCLUSIONS: Adherence to medication regimens for type 2 diabetes is strongly associated with metabolic control in an indigent population; African-Americans have lower adherence and worse metabolic control. Greater efforts are clearly needed to facilitate diabetes self-management behaviors of low-income populations and foster culturally sensitive and appropriate care for minority groups.

Can prescription refill feedback to physicians improve patient adherence?

BACKGROUND: Although adherence to long-term drug therapy is an important issue, the means to facilitate its assessment and improvement in clinical practice remain a challenge. OBJECTIVE: To evaluate the impact of prescription refill feedback and adherence education provided to primary care physicians. METHODS: We provided 83 resident and attending physicians at a university-based general internal medicine practice with refill adherence reports on each of 340 diabetic patients. An educational session on adherence assessment and improvement techniques was held, and all physicians received a written outline on this topic. Physician attitude toward the intervention and 6-month change in refill adherence (doses filled/doses prescribed) of their patient panels were assessed. A nonrandomized comparison group of patients receiving hypertension medications for whom the physicians did not receive feedback was also evaluated. RESULTS: The overall improvement in mean refill adherence was not significant (83.9% vs 86.0%, P=0.18). The educational session was attended by 53% of the physicians. The patient refill adherence of physicians attending the educational session improved by 5.0% (P<0.0009) with no significant change among patients of physicians not attending the session. There was no adherence change among patients for whom physicians did not receive refill feedback data, regardless of educational session attendance. CONCLUSIONS: Patients of physicians that received refill feedback and attended an educational session improved their refill adherence. After replication of these results in a randomized trial, broad implementation of this approach could have substantial impact from a public health perspective, given the ubiquity of prescription claims data.

The effect of physician feedback and an action checklist on diabetes care measures.

The objective was to evaluate whether physician feedback accompanied by an action checklist improved diabetes care process measures. Eighty-three physicians in an academic general medicine clinic were provided a single feedback report on the most recent date and result of diabetes care measures (glycosylated hemoglobin [A1c], urine microalbumin, serum creatinine, lipid levels, retinal examination) as well as recent diabetes medication refills with calculated dosing and adherence on 789 patients. An educational session regarding the feedback and adherence information was provided. The physicians were asked to complete a checklist accompanying the feedback on each of their patients, indicating requested actions with respect to follow-up, testing, and counseling. The physicians completed 82% of patient checklists, requesting actions consistent with patient needs on the basis of the feedback. Of the physicians, 93% felt the patient information and intervention format to be useful. The odds of urine microalbumin testing, serum creatinine, lipid profile, A1c, and retinal examination increased in the 6 months after the feedback. The increase was sustained at 1 year only for microalbumin and retinal exams. There was no significant change in refill adherence for the group overall after the feedback, although adherence did improve among patients of physicians attending the educational session. No significant change was noted in lipid or A1c levels during the study period. In conclusion, a simple physician feedback tool with action checklist can be both helpful and popular for improving rates of diabetes care guideline adherence. More complex interventions are likely required to improve diabetes outcomes.

Prevalence and functionality of electronic health records in internal medicine continuity clinics.

PURPOSE: Health information technology (HIT), particularly electronic health records (EHRs), will become universal in ambulatory practices, but the current roles and functions that HIT and EHRs play in the ambulatory clinic settings of internal medicine (IM) residents are unknown. METHOD: The authors conducted a Web-based survey from July 2007 to January 2008 to ascertain HIT prevalence and functionality. Respondents were directors of one or more ambulatory clinics where IM residents completed any required outpatient training, as identified by directors of accredited U.S. IM residencies. RESULTS: The authors identified 356 clinic directors from 264 accredited U.S. programs (70%); 221 directors (62%) completed the survey, representing 185 accredited programs (49%). According to responding directors, residents in 121 of 216 clinics (56%) had access to EHRs, residents in 147 of 219 clinics (67%) used some type of electronic data system (EDS) to manage patient information, and residents in 62 clinics (28% of 219 responding) used an EDS to generate lists of patients needing follow-up care. Compared with smaller IM training programs, programs with > or =50 trainees were more likely to have an EDS (67% versus 53%, P = .037), electronic prescription writer (57% versus 42%, P = .026), or EHR (63% versus 45%, P = .007). CONCLUSIONS: Resident ambulatory clinics seem to have greater adoption of HIT and EHRs than practicing physicians' ambulatory offices. Ample room for improvement exists, however, as electronic systems with suboptimal patient data, limited functionality, and reliance on multiple (paper and electronic) systems all hinder residents' ability to perform important care coordination activities.

Changing conversations: teaching safety and quality in residency training.

Improving patient safety and quality in health care is one of medicine's most pressing challenges. Residency training programs have a unique opportunity to meet this challenge by training physicians in the science and methods of patient safety and quality improvement (QI).With support from the Health Resources and Services Administration, the authors developed an innovative, longitudinal, experiential curriculum in patient safety and QI for internal medicine residents at the University of Virginia. This two-year curriculum teaches the critical concepts and skills of patient safety and QI: systems thinking and human factors analysis, root cause analysis (RCA), and process mapping. Residents apply these skills in a series of QI and patient safety projects. The constructivist educational model creates a learning environment that actively engages residents in improving the quality and safety of their medical practice.Between 2003 and 2005, 38 residents completed RCAs of adverse events. The RCAs identified causes and proposed useful interventions that have produced important care improvements. Qualitative analysis demonstrates that the curriculum shifted residents' thinking about patient safety to a systems-based approach. Residents completed 237 outcome assessments during three years. Results indicate that seminars met predefined learning objectives and were interactive and enjoyable. Residents strongly believe they gained important skills in all domains.The challenge to improve quality and safety in health care requires physicians to learn new knowledge and skills. Graduate medical education can equip new physicians with the skills necessary to lead the movement to safer and better quality of care for all patients.This article is part of a theme issue of Academic Medicine on the Title VII health professions training programs.

Patient safety in the ambulatory setting. A clinician-based approach.

BACKGROUND: Voluntary reporting of near misses/adverse events is an important but underutilized source of information on errors in medicine. To date, there is very little information on errors in the ambulatory setting and physicians have not traditionally participated actively in their reporting or analysis. OBJECTIVES: To determine the feasibility and effectiveness of clinician-based near miss/adverse event voluntary reporting coupled with systems analysis and redesign as a model for continuous quality improvement in the ambulatory setting. DESIGN: We report the initial 1-year experience of voluntary reporting by clinicians in the ambulatory setting, coupled with root cause analysis and system redesign by a patient safety committee made up of clinicians from the practice. SETTING: Internal medicine practice site of a large teaching hospital with 25,000 visits per year. MEASUREMENTS AND MAIN RESULTS: There were 100 reports in the 1-year period, increased from 5 in the previous year. Faculty physicians reported 44% of the events versus 22% by residents, 31% by nurses, and 3% by managers. Eighty-three percent were near misses and 17% were adverse events. Errors involved medication (47%), lab or x-rays (22%), office administration (21%), and communication (10%) processes. Seventy-two interventions were recommended with 75% implemented during the study period. CONCLUSION: This model of clinician-based voluntary reporting, systems analysis, and redesign was effective in increasing error reporting, particularly among physicians, and in promoting system changes to improve care and prevent errors. This process can be a powerful tool for incorporating error reporting and analysis into the culture of medicine.
