Geriatricians, general internists, and potentially inappropriate medications for a national sample of older adults.

BACKGROUND: Older adults are often prescribed medications that are potentially dangerous and geriatricians have specialized training in treating polypharmacy that may benefit these patients. To examine this, we compared potentially inappropriate medication (PIM) prescribing rates between geriatricians and similar general internists in the United States. METHODS: Using national cross-sectional data from 2013 to 2019, we compared annual PIM prescribing rates between 2815 outpatient geriatricians certified by the American Board of Internal Medicine in 1994-2018 and general internists matched 1:1 on IM certification exam score and year, residency exam pass rate, gender, and US birth and/or US medical school. PIM prescribing was based on the Healthcare Effectiveness Data and Information Set (HEDIS) PIM physician annual prescribing measures which consider medications flagged as potentially inappropriate in the American Geriatric Society Beers Criteria® guideline. We also examined prescribing of appropriate alternative medications. Prescribing rates were calculated as the percentage a physician's patients with Medicare fee-for-service part D enrollment seen in the outpatient setting in a given year (mean: 150 patients per physician) with a PIM prescription they prescribed. RESULTS: Across 30,677 physician-year observations, geriatricians were 16.7% less likely (95% confidence interval (CI): -19.8 to -13.7, p < 0.001) to prescribe a PIM (7.2% versus 8.7% of patients respectively) and 2.7% more likely (95% CI: 0.8 to 4.5, p = 0.004) to prescribe an appropriate alternative medication (52.0% versus 50.7% of patients respectively). Lower PIM prescribing was observed for most medication sub-types including central nervous system, anticholinergic, pain, and endocrine medications. In sensitivity analyses, differences in prescribing were similar when comparing recently trained physicians with more experienced physicians. CONCLUSION: Findings suggest geriatricians in the United States prescribe PIMs at lower rates than general internists. This highlights the value geriatricians provide as well as opportunities to embed key principles of geriatric care into internal medicine training and health care delivery systems.

Associations between initial American Board of Internal Medicine certification and maintenance of certification status of attending physicians and in-hospital mortality of patients with acute myocardial infarction or congestive heart failure: a retrospective cohort study of hospitalisations in Pennsylvania, USA.

OBJECTIVE: To determine whether internists' initial specialty certification and the maintenance of that certification (MOC) is associated with lower in-hospital mortality for their patients with acute myocardial infarction (AMI) or congestive heart failure (CHF). DESIGN: Retrospective cohort study of hospitalisations in Pennsylvania, USA, from 2012 to 2017. SETTING: All hospitals in Pennsylvania. PARTICIPANTS: All 184 115 hospitalisations for primary diagnoses of AMI or CHF where the attending physician was a self-designated internist. PRIMARY OUTCOME MEASURE: In-hospital mortality. RESULTS: Of the 2575 physicians, 2238 had initial certification and 820 were eligible for MOC. After controlling for patient demographics and clinical characteristics, hospital-level factors and physicians' demographic and medical school characteristics, both initial certification and MOC were associated with lower mortality. The adjusted OR for initial certification was 0.835 (95% CI 0.756 to 0.922; p<0.001). Patients cared for by physicians with initial certification had a 15.87% decrease in mortality compared with those cared for by non-certified physicians (mortality rate difference of 5.09 per 1000 patients; 95% CI 2.12 to 8.05; p<0.001). The adjusted OR for MOC was 0.804 (95% CI 0.697 to 0.926; p=0.003). Patients cared for by physicians who completed MOC had an 18.91% decrease in mortality compared with those cared for by MOC lapsed physicians (mortality rate difference of 6.22 per 1000 patients; 95% CI 2.0 to 10.4; p=0.004). CONCLUSIONS: Initial certification was associated with lower mortality for AMI or CHF. Moreover, for patients whose physicians had initial certification, an additional advantage was associated with its maintenance.

Analysis of Performance Trends from 2010-2019 on the American Board of Internal Medicine Nephrology Certifying Exam.

BACKGROUND: The pass rate on the American Board of Internal Medicine (ABIM) nephrology certifying exam has declined and is among the lowest of all internal medicine (IM) subspecialties. In recent years, there have also been fewer applicants for the nephrology fellowship match. METHODS: This retrospective observational study assessed how changes between 2010 and 2019 in characteristics of 4094 graduates of US ACGME-accredited nephrology fellowship programs taking the ABIM nephrology certifying exam for the first time, and how characteristics of their fellowship programs were associated with exam performance. The primary outcome measure was performance on the nephrology certifying exam. Fellowship program pass rates over the decade were also studied. RESULTS: Lower IM certifying exam score, older age, female sex, international medical graduate (IMG) status, and having trained at a smaller nephrology fellowship program were associated with poorer nephrology certifying exam performance. The mean IM certifying exam percentile score among those who subsequently took the nephrology certifying exam decreased from 56.7 (SD, 27.9) to 46.1 (SD, 28.7) from 2010 to 2019. When examining individuals with comparable IM certifying exam performance, IMGs performed less well than United States medical graduates (USMGs) on the nephrology certifying exam. In 2019, only 57% of nephrology fellowship programs had aggregate 3-year certifying exam pass rates ≥80% among their graduates. CONCLUSIONS: Changes in IM certifying exam performance, certain trainee demographics, and poorer performance among those from smaller fellowship programs explain much of the decline in nephrology certifying exam performance. IM certifying exam performance was the dominant determinant.

The association between physician knowledge and inappropriate medications for older populations.

BACKGROUND: Older patients are often prescribed potentially inappropriate medications (PIMs) given their age. We measured the association between a physician's general knowledge and their PIM prescribing. METHODS: Using a 2013-2017 cross-sectional design, we related a general internist's knowledge (n = 8196) to their prescribing of PIMs to fee-for-service Medicare beneficiaries, age ≥ 66 years with part D coverage, which they saw in the outpatient setting the year after their exam (n = 875,132). Physician knowledge was based on the American Board of Internal Medicine's (ABIM) Internal Medicine Maintenance of Certification (IM-MOC) exam scores. Medications included 72 PIMs from the American Geriatric Society's Beers Criteria and appropriate alternatives to these medications. Logistic regressions controlled for physicians practice/training characteristics and patient-risk factors. RESULTS: Annually, 11.0% of patients received a PIM and 57.2% received an appropriate alternative medication. Patients seen by physicians scoring in the top versus bottom quartile were 8.6% less likely (95% confidence interval [CI]: -12.7 to -4.5, p < 0.001) to be prescribed a PIM and 4.7% more likely (95% CI: 1.7 to 7.6, p = 0.001) to be prescribed an appropriate alternative medication. The difference in PIM prescribing grew to 12.1% fewer (95% CI: -15.1 to -9.1) patients when limiting the sample to the 58.9% of patients being prescribed a PIM or appropriate alternative medication. Among patients receiving any medication, this was similar to the percent difference in PIM prescribing between solo and large practices (≥50 physicians, -10.2%, 95% CI: 13.6-6.5, p < 0.001) or between group and academic practices (-11.7%, 95% CI: -15.3 to -7.9, p < 0.001). PIM prescribing was more positively associated with patient characteristics including age, gender, and total number of medications prescribed. CONCLUSIONS: Better physician general knowledge, as measured by an ABIM exam, was associated with fewer PIM prescriptions. Future research should examine whether general educational interventions, such as MOC, effect PIM prescribing.

Clinical Knowledge and Trends in Physicians' Prescribing of Opioids for New Onset Back Pain, 2009-2017.

Importance: Opioid musculoskeletal pain overprescribing was widespread in the mid-2000s. The degree to which prescribing changed as awareness of the danger grew among physicians with different levels of clinical knowledge remains unstudied. Objective: To compare the association of clinical knowledge with opioid prescribing from 2009 to 2011 when prescribing peaked nationally with 2015 to 2017 when guidelines shifted away from opioid prescribing. Design, Setting, and Participants: This cross-sectional study included 10 246 midcareer general internal medicine physicians in the United States who saw patients who were Medicare beneficiaries with Part D enrollment from 2009 to 2017. Main Outcomes and Measures: Any opioid prescription and high dosage or long duration (HDLD) (>7 days or >50 daily morphine milligram equivalents) opioid prescriptions filled within 7 days of applicable visits for new low back pain concerns. Associations between opioid prescribing for new low back pain concerns during outpatient visits and clinical knowledge measured by prior year American Board of Internal Medicine (ABIM) Maintenance of Certification examination performance were estimated using serial cross-sectional logit regressions. Regression covariates included yearly examination quartile (ie, knowledge quartile) interacted with 3-year group dummies (ie, early: 2009-2011; middle: 2012-2014; late: 2015-2017), state and year dummies, physician, practice, patient characteristics, and state opioid regulations. Results: Of the 55 387 low back pain visits included in this study, 37 185 (67.1%) were visits with female patients, 41 978 (75.8%) were with White patients, and the mean (SE) age of patients was 76.2 (<0.01) years. The rate of opioid prescribing was 21.6% (11 978) for any opioid prescription and 17.6% (9759) for HDLD prescriptions. From 2009 to 2011, visits with physicians in the highest and lowest knowledge quartiles had similar adjusted opioid prescribing rates with a 0.5 (95% CI, -1.9 to 3.0) percentage point difference. By 2015 to 2017, visits with physicians in the highest knowledge quartile prescribed opioids less frequently that physicians in the lowest knowledge quartile (4.6 percentage point difference; 95% CI, -7.5 to -1.8 percentage points). Visits in which HDLD opioids were prescribed showed no difference in the early period but showed a difference in the late period when comparing physicians in the highest and lowest knowledge quartiles (early period: difference -0.1; 95% CI, -2.4 to 2.2 percentage points; late period difference: 4.8; 95% CI, -7.4 to -2.1 percentage points). Conclusions and Relevance: In this cross-sectional study, when the standard of care shifted away from routine opioid prescribing, physicians who performed well on an ABIM examination were less likely to prescribe opioids for back pain than physicians who performed less well on the examination.

Protective effect of Corynoline on the CFA induced Rheumatoid arthritis via attenuation of oxidative and inflammatory mediators.

Rheumatoid arthritis (RA) is a long-standing and growing autoimmune disease. Therefore, the present study was intended to investigate the effect of Corynoline (COR) on CFA induced rheumatoid arthritis in a rat model. Results suggested that COR causes significant reduction in paw swelling, edema, arthritis score, thymus and spleen indexes and neutrophil infiltration (p < 0.01). Moreover, the levels of inflammatory cytokines (interleukin- 1ß, -6, and -17, and TNF-α) and anti-collagen II-specific immunoglobulins (IgG1 and IgG2a) were decreased significantly (p < 0.01) together with increase in antioxidant enzymes (SOD, CAT, and GSH) (p < 0.01) in COR-treated group in dose-dependent manner. In western blot analysis, COR-treated group showed concentration-dependent reduction of expression of COX-2, 5-LOX and NF-p65 as compared to CFA rats. Moreover, COR-treated group showed mild inflammation of cartilage with fewer cartilage erosion and synovititis with most significant reversal of arthritic features in the rats treated with 30 mg/kg. It has been concluded that, COR alleviates oxidative stress and inflammation in arthritic rats, thus verifying its anti-rheumatoid arthritis property.

Association of Regional Practice Environment Intensity and the Ability of Internists to Practice High-Value Care After Residency.

Importance: Use of health care services and physician practice patterns have been shown to vary widely across the United States. Although practice patterns-in particular, physicians' ability to provide high-quality, high-value care-develop during training, the association of a physician's regional practice environment with that ability is less well understood. Objective: To examine the association between health care intensity in the region where physicians practice and their ability to practice high-value care, specifically for physicians whose practice environment changed due to relocation after residency. Design, Setting, and Participants: This cohort study included a national sample of 3896 internal medicine physicians who took the 2002 American Board of Internal Medicine initial certification examination followed approximately 1 decade (April 21, 2011, to May 7, 2015) later by the Maintenance of Certification (MOC) examination. At the time of the MOC examination, 2714 of these internists were practicing in a new region. Data were analyzed from March 6, 2016, to May 21, 2018. Exposures: Intensity of care in the Dartmouth Atlas hospital referral region (HRR), measured by per-enrollee end-of-life physician visits (primary) and current practice type (secondary). Main Outcomes and Measures: The outcome, a physician's ability to practice high-value care, was assessed using the Appropriately Conservative Management (ACM) score on the MOC examination, measuring performance across all questions for which the correct answer was the most conservative option. The exposure, regional health care intensity, was measured as per-enrollee end-of-life physician visits in the Dartmouth Atlas HRR of the physician's practice. Results: Among the 3860 participating internists included in the analysis (2030 men [52.6%]; mean [SD] age, 45.6 [4.5] years), those who moved to regions in the quintile of highest health care intensity had an ACM score 0.22 SD lower (95% CI, -0.32 to -0.12) than internists who moved to regions in the quintile of lowest intensity, controlling for postresidency ACM scores. This difference reflected scoring in the 44th compared with the 53rd percentile of all examinees. This association was mildly attenuated (0.18 SD less; 95% CI, -0.28 to -0.09) after adjustment for physician and practice characteristics. Conclusions and Relevance: This study found that practice patterns of internists who relocate after residency training appear to migrate toward norms of the new region. The demands of practicing in high-intensity regions may erode the ability to practice high-value conservative care.

Role of Critical Care Medicine Training in the Cardiovascular Intensive Care Unit: Survey Responses From Dual Certified Critical Care Cardiologists.

Background Cardiovascular intensive care units ( CICUs ) have evolved from coronary care wards into distinct units for critically ill patients with primary cardiac diseases, often suffering from illnesses that cross multiple disciplines. Mounting evidence has demonstrated improved survival with the incorporation of dedicated CICU providers with expertise in critical care medicine ( CCM ). This is the first study to systematically survey dual certified physicians in order to assess the relevance of CCM training to contemporary CICU care. Methods and Results Utilizing American Board of Internal Medicine data through 2014, 397 eligible physicians had obtained initial certification in both cardiovascular disease and CCM . A survey to delineate the role of critical care training in the CICU was provided to these physicians. Among those surveyed, 120 physicians (30%) responded. Dual certified physicians reported frequent use of their CCM skills in the CICU , highlighting ventilator management, multiorgan dysfunction management, end-of-life care, and airway management. The majority (85%) cited these skills as the reason CCM training should be prioritized by future CICU providers. Few (17%) agreed that general cardiology fellowship alone is currently sufficient to care for patients in the modern CICU . Furthermore, there was a consensus that there is an unmet need for cardiologists trained in CCM (70%) and that CICU s should adopt a level system similar to trauma centers (61%). Conclusions Citing specific skills acquired during CCM training, dual certified critical care cardiologists reported that their additional critical care experience was necessary in their practice to effectively deliver care in the modern CICU .

Effects of gender in resident evaluations and certifying examination pass rates.

BACKGROUND: Though the proportion of female Internal Medicine (IM) residents and faculty has increased, there is minimal large scale modern data comparing resident performance by gender. This study sought to examine the effects of resident and faculty gender on resident evaluations. METHODS: Retrospective observational study over 5 years in a single IM program. IM certifying examination pass rates were obtained from the American Board of IM. RESULTS: Four hundred eighty-eight residents (195 women, 293 men), evaluated by 430 attending physicians (163 women, 270 men) were included. Twelve thousand six hundred eighty-one evaluations between 2007 and 2012 were analyzed. Female residents scored higher in two domains (Medical Interviewing, and Interpersonal and Communication Skills) (p < 0.01 for each), with no significant difference between genders for the other domains (Medical Knowledge, Overall Patient Care, Physical Examination, Procedural Skills, Professionalism, Practice Based Learning and Improvement, System Based Practices and Overall score). There were no differences in scoring between female and male attending physicians. There were no differences in certifying examination scores between women and men among graduating residents. National pass rates for women were not statistically different to pass rates for men from 1987 to 2015. CONCLUSIONS: Data from one large academic medical center demonstrate higher ratings for female residents on performance domains reflecting bedside care and interpersonal skills, with similar scores for medical knowledge and remaining domains. No significant difference was seen locally in certifying examination scores, nor in recent national pass rates, an objective measure of medical knowledge. Despite imbalanced female representation in areas of medicine, our data suggest that gender-based disparities in Internal Medicine resident medical knowledge and physician competency are no longer present.

Do State Continuing Medical Education Requirements for Physicians Improve Clinical Knowledge?

OBJECTIVE: To evaluate the effect of state continuing medical education (CME) requirements on physician clinical knowledge. DATA SOURCES: Secondary data for 19,563 general internists who took the Internal Medicine Maintenance of Certification (MOC) examination between 2006 and 2013. STUDY DESIGN: We took advantage of a natural experiment resulting from variations in CME requirements across states over time and applied a difference-in-differences methodology to measure associations between changes in CME requirements and physician clinical knowledge. We measured changes in clinical knowledge by comparing initial and MOC examination performance 10 years apart. We constructed difference-in-differences estimates by regressing examination performance changes against physician demographics, county and year fixed effects, trend-state indicators, and state CME change indicators. DATA COLLECTION: Physician data were compiled by the American Board of Internal Medicine. State CME policies were compiled from American Medical Association reports. PRINCIPAL FINDINGS: More rigorous CME credit-hour requirements (mostly implementing a new requirement) were associated with an increase in examination performance equivalent to a shift in examination score from the 50th to 54th percentile. CONCLUSIONS: Among physicians required to engage in a summative assessment of their clinical knowledge, CME requirements were associated with an improvement in physician clinical knowledge.

Assessing the Quality of Osteoporosis Care in Practice.

BACKGROUND: Patients with osteoporosis can sustain fractures following falls or other minimal trauma. This risk of fracture can be reduced through appropriate diagnostic testing, pharmacologic therapy, and other readily measured standards of care. OBJECTIVES: Our aim was to develop a credible clinical performance assessment to measure physicians' quality of osteoporosis care, and determine reasonable performance standards for both competent and excellent care. DESIGN: This was a retrospective cohort study. PARTICIPANTS: Three hundred and eighty one general internists and subspecialists with time-limited board certification were included in the study. MAIN MEASURES: Performance rates on eight evidence-based measures were obtained from the American Board of Internal Medicine (ABIM) Osteoporosis Practice Improvement Module® (PIM), a web-based tool that uses medical chart reviews to help physicians assess and improve care. We applied a patented methodology, using an adaptation of the Angoff standard-setting method and the Dunn-Rankin method, with an expert panel skilled in osteoporosis care to form a composite and establish standards for both competent and excellent care. Physician and practice characteristics, including a practice infrastructure score based on the Physician Practice Connections Readiness Survey (PPC-RS), were used to examine the validity of the inferences made from the composite scores. KEY RESULTS: The mean composite score was 67.54 out of 100 maximum points with a reliability of 0.92. The standard for competent care was 46.87, and for excellent care it was 83.58. Both standards had high classification accuracies (0.95). Sixteen percent of physicians performed below the competent care standard, while 22 % met the excellent care standard. Specialists scored higher than generalists, and better practice infrastructure was associated with higher composite scores, providing some validity evidence. CONCLUSIONS: We developed a rigorous methodology for assessing physicians' osteoporosis care. Clinical performance feedback relative to absolute standards of care provides physicians with a meaningful approach to self-evaluation to improve patient care.

Physician performance assessment: prevention of cardiovascular disease.

Given the rising burden of healthcare costs, both patients and healthcare purchasers are interested in discerning which physicians deliver quality care. We proposed a methodology to assess physician clinical performance in preventive cardiology care, and determined a benchmark for minimally acceptable performance. We used data on eight evidence-based clinical measures from 811 physicians that completed the American Board of Internal Medicine's Preventive Cardiology Practice Improvement Module(SM) to form an overall composite score for preventive cardiology care. An expert panel of nine internists/cardiologists skilled in preventive care for cardiovascular disease used an adaptation of the Angoff standard-setting method and the Dunn-Rankin method to create the composite and establish a standard. Physician characteristics were used to examine the validity of the inferences made from the composite scores. The mean composite score was 73.88 % (SD = 11.88 %). Reliability of the composite was high at 0.87. Specialized cardiologists had significantly lower composite scores (P = 0.04), while physicians who reported spending more time in primary, longitudinal, and preventive consultative care had significantly higher scores (P = 0.01), providing some evidence of score validity. The panel established a standard of 47.38 % on the composite measure with high classification accuracy (0.98). Only 2.7 % of the physicians performed below the standard for minimally acceptable preventive cardiovascular disease care. Of those, 64 % (N = 14) were not general cardiologists. Our study presents a psychometrically defensible methodology for assessing physician performance in preventive cardiology while also providing relative feedback with the hope of heightening physician awareness about deficits and improving patient care.

Physicians' actions and influence, such as aggressive blood pressure control, greatly improve the health of diabetes patients.

Managing diabetes and preventing its associated morbidities require active partnerships between physicians and patients. Studies to date lack the level of detail to quantify the degree to which interventions that are more controlled by physicians influence outcomes versus those that are more controlled by patients. Using the Archimedes model, we simulated a thirty-year clinical trial and compared the effects of three sets of interventions over which physicians have progressively less control: compliance with process-of-care standards, such as conducting foot and retinal exams and screening for signs of early kidney disease; control of biomarkers, such as hemoglobin A1c and blood pressure; and lifestyle modifications, such as patients' switching to healthier diets and losing weight. We found that if all US adults diagnosed with type 2 diabetes met quality targets in all of these areas, they would experience a nearly 16 percent increase in quality-adjusted life-years and a nearly 23 percent reduction in fifteen-year mortality over the thirty-year simulation period. Meeting aggressive biomarker targets yielded the most benefit. Meeting conservative biomarker targets came next, followed closely by meeting process-of-care standards. The incremental benefits of complying fully with diet and smoking cessation yielded the least benefit. Thus, through measures more readily within their control, and through collaboration with their patients, physicians have a substantial opportunity to improve outcomes. These findings can inform policy makers' rational resource allocation decisions and the design of programs to improve diabetes care.

Gaps in quality of diabetes care in internal medicine residency clinics suggest the need for better ambulatory care training.

To ensure that medical residents will be prepared to deliver consistently high-quality care, they should be trained in settings that provide such care. Residents in internal medicine, particularly, need to learn good care habits in order to meet the needs of patients with diabetes and other common chronic and high-impact illnesses. To assess the strength of such training, we compared the quality of medical care provided in sixty-seven US internal medicine residency ambulatory clinics with the quality of care provided by 703 practicing general internists. We found significant quality gaps in process, intermediate outcome, and patient-experience measures. These inadequacies in ambulatory training for internal medicine residents must be addressed by policy makers and educators-for example, by accelerating the movement toward new residency curricula that emphasize competency-based training.

An assessment of patient-based and practice infrastructure-based measures of the patient-centered medical home: do we need to ask the patient?

OBJECTIVE: To examine the importance of patient-based measures and practice infrastructure measures of the patient-centered medical home (PCMH). DATA SOURCES: A total of 3,671 patient surveys of 202 physicians completing the American Board of Internal Medicine (ABIM) 2006 Comprehensive Care Practice Improvement Module and 14,457 patient chart reviews from 592 physicians completing ABIM's 2007 Diabetes and Hypertension Practice Improvement Module. METHODOLOGY: We estimated the association of patient-centered care and practice infrastructure measures with patient rating of physician quality. We then estimated the association of practice infrastructure and patient rating of care quality with blood pressure (BP) control. RESULTS: Patient-centered care measures dominated practice infrastructure as predictors of patient rating of physician quality. Having all patient-centered care measures in place versus none was associated with an absolute 75.2 percent increase in the likelihood of receiving a top rating. Both patient rating of care quality and practice infrastructure predicted BP control. Receiving a rating of excellent on care quality from all patients was associated with an absolute 4.2 percent improvement in BP control. For reaching the maximum practice-infrastructure score, this figure was 4.5 percent. CONCLUSION: Assessment of physician practices for PCMH qualification should consider both patient based patient-centered care measures and practice infrastructure measures.

The association between physicians' cognitive skills and quality of diabetes care.

PURPOSE: To examine the association between physicians' cognitive skills and their performance on a composite measure of diabetes care that included process, outcome, and patient experience measures. METHOD: The sample was 676 physicians from the United States with time-limited certification in general internal medicine between 2005 and 2009. Scores from the American Board of Internal Medicine (ABIM) internal medicine maintenance of certification (MOC) examination were used to measure practicing physicians' cognitive skills (scores reflect fund of medical knowledge, diagnostic acumen, and clinical judgment). Practice performance was assessed using a diabetes composite measure aggregated from clinical and patient experience measures obtained from the ABIM Diabetes Practice Improvement Module. RESULTS: Using multiple regression analyses and controlling for physician and patient characteristics, MOC examination scores were significantly associated with the diabetes composite scores (ß = .22, P < .001). The association was particularly stronger with intermediate outcomes than with process and patient experience measures. Performance in the endocrine disease content domain of the examination was more strongly associated with the diabetes composite scores (ß = .19, P < .001) than the performance in other medical content domains (ß = .06-.14). CONCLUSIONS: Physicians' cognitive skills significantly relate to their performance on a comprehensive composite measure for diabetes care. Although significant, the modest association suggests that there are unique aspects of physician competence captured by each assessment alone and that both must be considered when assessing a physician's ability to provide high-quality care.

Setting a fair performance standard for physicians' quality of patient care.

BACKGROUND: Assessing physicians' clinical performance using statistically sound, evidence-based measures is challenging. Little research has focused on methodological approaches to setting performance standards to which physicians are being held accountable. OBJECTIVE: Determine if a rigorous approach for setting an objective, credible standard of minimally-acceptable performance could be used for practicing physicians caring for diabetic patients. DESIGN: Retrospective cohort study. PARTICIPANTS: Nine hundred and fifty-seven physicians from the United States with time-limited certification in internal medicine or a subspecialty. MAIN MEASURES: The ABIM Diabetes Practice Improvement Module was used to collect data on ten clinical and two patient experience measures. A panel of eight internists/subspecialists representing essential perspectives of clinical practice applied an adaptation of the Angoff method to judge how physicians who provide minimally-acceptable care would perform on individual measures to establish performance thresholds. Panelists then rated each measure's relative importance and the Dunn-Rankin method was applied to establish scoring weights for the composite measure. Physician characteristics were used to support the standard-setting outcome. KEY RESULTS: Physicians abstracted 20,131 patient charts and 18,974 patient surveys were completed. The panel established reasonable performance thresholds and importance weights, yielding a standard of 48.51 (out of 100 possible points) on the composite measure with high classification accuracy (0.98). The 38 (4%) outlier physicians who did not meet the standard had lower ratings of overall clinical competence and professional behavior/attitude from former residency program directors (p = 0.01 and p = 0.006, respectively), lower Internal Medicine certification and maintenance of certification examination scores (p = 0.005 and p < 0.001, respectively), and primarily worked as solo practitioners (p = 0.02). CONCLUSIONS: The standard-setting method yielded a credible, defensible performance standard for diabetes care based on informed judgment that resulted in a reasonable, reproducible outcome. Our method represents one approach to identifying outlier physicians for intervention to protect patients.

The comprehensive care project: measuring physician performance in ambulatory practice.

OBJECTIVE: To investigate the feasibility, reliability, and validity of comprehensively assessing physician-level performance in ambulatory practice. DATA SOURCES/STUDY SETTING: Ambulatory-based general internists in 13 states participated in the assessment. STUDY DESIGN: We assessed physician-level performance, adjusted for patient factors, on 46 individual measures, an overall composite measure, and composite measures for chronic, acute, and preventive care. Between- versus within-physician variation was quantified by intraclass correlation coefficients (ICC). External validity was assessed by correlating performance on a certification exam. DATA COLLECTION/EXTRACTION METHODS: Medical records for 236 physicians were audited for seven chronic and four acute care conditions, and six age- and gender-appropriate preventive services. PRINCIPAL FINDINGS: Performance on the individual and composite measures varied substantially within (range 5-86 percent compliance on 46 measures) and between physicians (ICC range 0.12-0.88). Reliabilities for the composite measures were robust: 0.88 for chronic care and 0.87 for preventive services. Higher certification exam scores were associated with better performance on the overall (r = 0.19; p<.01), chronic care (r = 0.14, p = .04), and preventive services composites (r = 0.17, p = .01). CONCLUSIONS: Our results suggest that reliable and valid comprehensive assessment of the quality of chronic and preventive care can be achieved by creating composite measures and by sampling feasible numbers of patients for each condition.

Current yardsticks may be inadequate for measuring quality improvements from the medical home.

Health reform legislation grants authority for patient-centered medical home pilot projects to test changes in the way primary care is provided. There is concern that using a measurement tool to qualify medical homes that is solely based on the presence or absence of "system elements" may miss the point conceptually and lead physicians astray in attempts to transform their entire practices. To find out whether and how practice characteristics explain health care quality, we examined risk-adjusted composite measures of quality for common chronic and acute care conditions and preventive care from 202 general internists working primarily in small primary care office settings. We found that current conceptions and measures of what constitutes "successful" practice systems and care are incomplete, and have limited associations with measures of health care quality. Future research should explore more fully the issues around physician competence, including competence in systems and quality improvement; the interactive nature of clinical practice; and other important system elements not captured by current tools.

[The use of a pneumatic tourniquet in total knee arthroplasty: a prospective, randomized study].

OBJECTIVE: To determine the value of the use of a pneumatic tourniquet in total knee arthroplasty. METHODS: Sixty patients were prospectively randomized into 2 groups, one group underwent total knee replacement with a tourniquet (n = 30) and one without (n = 30). Operating time, blood loss, postoperative mean morphine requirement, swelling, ecchymosis, earlier straight-leg raising and postoperative knee flexion were measured in both groups. RESULTS: There was no significant difference in the total blood loss between the 2 groups although the intraoperative blood loss was significantly greater in those without a tourniquet. The mean morphine requirement, postoperative swelling, scope of ecchymosis, earlier straight-leg raising and postoperative knee flexion in the patients that had surgery without a tourniquet were significantly better than those with a tourniquet. CONCLUSION: Knee arthroplasty operation with the use of a tourniquet has only small benefits on the total blood loss, but hinder in patients' early postoperative rehabilitation exercises.
