The patient-centered medical home model of primary care has received considerable attention for its potential to improve outcomes and reduce health care costs. Yet little information exists about the model's ability to achieve these goals for Medicaid patients. We sought to evaluate the effect of patient-centered medical home certification of Louisiana primary care clinics on the quality and cost of care over time for a Medicaid population. We used a quasi-experimental pre-post design with a matched control group to assess the effect of medical home certification on outcomes. We found no impact on acute care use and modest support for reduced costs and primary care use among medical homes serving higher proportions of chronically ill patients. These findings provide preliminary results related to the ability of the patient-centered medical home model to improve outcomes for Medicaid beneficiaries. The findings support a case-mix-adjusted payment policy for medical homes going forward.

Medical school deanship in the US has evolved during the past 200 years as the complexity of the US health care system has evolved. With the introduction of Medicare and Medicaid and the growth of the National Institutes of Health, the 19th-century and first half of the 20th-century role of the medical school dean as guild master transformed into that of resource allocator as faculty practice plans grew in scope and grew as an important source of medical school and university revenue. By 2000, the role of the medical school dean had transformed into that of CEO, with the dean having control over school mission and strategy, faculty practice plans, education, research dollars, and philanthropy. An alternative path to the Dean/CEO model has developed-the System Dean, who functions as a team player within a broader health system that determines the mission for the medical school and the related clinical enterprise. In this paper, the authors discuss the evolution of the medical school dean with respect to scope of authority and role within the health care system.

Object This study analyses inappropriate use of emergency department (ED) services among type 2 diabetics under an evidence-based management programme. Methods Using 1999-2006 databases of Louisiana Health Care Services Division (HCSD) eight public hospitals ED visits among the uninsured and other patients in Louisiana, we termed urgent ED visits appropriate and less-urgent visits inappropriate. Eliminating weekend ED visits, 17 458 urgent and 22 395 less-urgent visits by 8596 patients were analysed, using generalized estimating equation methods. Results Caucasians were 0.82 times (95% CI: 0.751–0.889) less likely to use the ED inappropriately compared with African Americans. Patients with commercial insurance, Medicaid and Medicare used the ED more inappropriately than uninsured, with odds ratios of 1.28, 1.32 and 1.28, respectively. Patients hospitalized the prior year were 0.84 times (95% CI: 1.08–1.31) less likely for inappropriate. Patients in larger hospitals used the ED more inappropriately, with an odds ratio of 1.44 (95% CI: 1.32–1.56). Conclusions The study suggests that inappropriate use of the ED among diabetic patients in an evidence-based management programme is more likely to occur among African American, patients with insurance coverage and those seeking care in larger hospitals. Reinforcing the regular use of clinic services for diabetes management, providing clinic access in off-hours, and engaging the health plans in providing incentives for more appropriate use of the ED might reduce inappropriate ED visits. Notably, uninsured patients with diabetes from HCSD were more efficient users of the ED.

Objective Determine the degree of congruence between several measures of adverse events. Design Cross-sectional study to assess frequency and type of adverse events identified using a variety of methods. Setting Mayo Clinic Rochester hospitals. Participants All inpatients discharged in 2005 ( n = 60 599). Interventions Adverse events were identified through multiple methods: (i) Agency for Healthcare Research and Quality-defined patient safety indicators (PSIs) using ICD-9 diagnosis codes from administrative discharge abstracts, (ii) provider-reported events, and (iii) Institute for Healthcare Improvement Global Trigger Tool with physician confirmation. PSIs were adjusted to exclude patient conditions present at admission. Main outcome measure Agreement of identification between methods. Results About 4% (2401) of hospital discharges had an adverse event identified by at least one method. Around 38% (922) of identified events were provider-reported events. Nearly 43% of provider-reported adverse events were skin integrity events, 23% medication events, 21% falls, 1.8% equipment events and 37% miscellaneous events. Patients with adverse events identified by one method were not usually identified using another method. Only 97 (6.2%) of hospitalizations with a PSI also had a provider-reported event and only 10.5% of provider-reported events had a PSI. Conclusions Different detection methods identified different adverse events. Findings are consistent with studies that recommend combining approaches to measure patient safety for internal quality improvement. Potential reported adverse event inconsistencies, low association with documented harm and reporting differences across organizations, however, raise concerns about using these patient safety measures for public reporting and organizational performance comparison.

Academic Health Sciences Centres (AHSCs) have long been viewed much as the historic battleship - possessing great force, power and bulk, but increasingly vulnerable to forays of lighter and more agile competitors. This commentary reviews the efforts of leaders of AHSCs in the United States to reposition their institutions at the centre of integrated delivery systems, partly as a result of greatly increased reliance on clinical revenue to support the historic teaching mission. While Lozon and Fox point to increased involvement of AHSCs in broad regional systems of care financed through a coordinated strategy, integrated systems in the United States may be fragmenting as marketplace-driven financial schemes actually discourage integrated care. From the perspective of organizational theory, the future seems to imply a diversification of organizational forms for the AHSCs in the United States, with a corresponding strategy of lessening reliance on clinical revenues through enhancement of research funding.

Leadership theory has identified leadership as a process or skill of transformation of organizations and society. Managerial theorists have seen leadership as a role within management, and have argued from a distinctly organizational perspective. During the last decade, mental health executives have gravitated from the leadership is policy emphasis to one of management accommodation to major changes in the health environment. The most noteworthy of these changes has been the dominance of private markets in health and the introduction throughout the mental health services sector of management techniques of managed care. Leadership is once again ascendant as a result of the failure of several of these initiatives, notably prior authorization of care, and a renewed public policy emphasis on needs of persons who are mentally ill. Major opportunities confronting the contemporary leader/manager include advocacy, diversity, and information management.

Jinan Liu,1 Lizheng Shi,2,3 Oliver Sartor,3 Richard Culbertson2,31HealthCore, Wilmington, DE, USA; 2School of Public Health and Tropical Medicine, Tulane University, New Orleans, LA, USA; 3School of Medicine, Tulane University, New Orleans, LA, USABackground: The most recent randomized controlled trial in a predominantly prostate-specific antigen-detected prostate cancer (PC) population found a nonsignificant reduction in mortality from radical prostatectomy (RP) compared to conservative management. The optimal treatment for clinically localized prostate cancer is anything but clear. The PC-specific mortality and all-cause mortality were compared between primary androgen-deprivation treatment (PADT) and RP, both as monotherapy, among clinically localized PC patients.Methods: A retrospective cohort study among PC patients in Surveillance, Epidemiology and End Results-Medicare data with a median follow up of 2.87 years in the PADT cohort and 2.95 years in the RP cohort. Propensity score-matching was employed to adjust for the observed selection bias. PC-specific mortality and all-cause mortality were modeled using the Fine and Gray competing risk model and Cox proportional hazards model, respectively. The independent variables in these models included age, race, Gleason score risk groups, T-score, prostate-specific antigen, Charlson comorbidity, and index year of treatment initiation.Results: After propensity score-matching, there were 1624 in the PADT cohort and 1624 in the RP cohort. All baseline values were comparable (all P-values >0.35). There were a total of 266 deaths (16.38%) and 60 (3.69%) PC-specific deaths among PADT recipients, while there were 56 (3.45%) deaths and four (0.25%) PC-specific deaths among RP recipients. According to the Kaplan–Meier estimation, the 8-year survival rate was 43.39% in the PADT cohort and 79.62% in the RP cohort. PADT was associated with increased risk of overall mortality (hazard ratio = 2.98, 95% confidence interval 2.35–3.79; P < 0.001) and increased risk of PC-specific mortality (hazard ratio = 12.47, 95% confidence interval 4.48–34.70; P < 0.001).Conclusion: With adjustment for the observed selection bias, PADT was associated with increased all-cause mortality and PC-specific mortality when compared to RP.Keywords: prostate cancer, primary androgen-deprivation treatment, radical prostatectomy, survival

Background No outcome studies have longitudinally and systematically compared the effects of hospital and surgeon volume on breast cancer surgery costs in an Asian population. This study purposed to evaluate the use of hospital and surgeon volume for predicting breast cancer surgery costs. Methods This cohort study retrospectively analyzed 97,215 breast cancer surgeries performed from 1996 to 2010. Relationships between volumes and costs were analyzed by propensity score matching and by hierarchical linear regression. Results The mean breast cancer surgery costs for all breast cancer surgeries performed during the study period was $1485.3 dollars. The average breast cancer surgery costs for high-volume hospitals and surgeons were 12% and 26% lower, respectively, than those for low-volume hospitals and surgeons. Propensity score matching analysis showed that the average breast cancer surgery costs for breast cancer surgery procedures performed by high-volume hospitals ($1428.6 dollars) significantly differed from the average breast cancer surgery costs of those performed by low-/medium-volume hospitals ($1514.0 dollars) and that the average breast cancer surgery costs of procedures performed by high-volume surgeons ($1359.0 dollars) significantly differed from the average breast cancer surgery costs of those performed by low-/medium-volume surgeons ($1550.3 dollars) (P Conclusions The factors significantly associated with hospital resource utilization for this procedure included age, surgical type, Charlson co-morbidity index score, hospital type, hospital volume, and surgeon volume. The data indicate that analyzing and emulating the treatment strategies used by high-volume hospitals and by high-volume surgeons may reduce overall breast cancer surgery costs.

The purpose of this study was to validate the use of artificial neural network (ANN) models for predicting quality of life (QOL) after breast cancer surgery and to compare the predictive capability of ANNs with that of linear regression (LR) models. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and its supplementary breast cancer measure were completed by 402 breast cancer patients at baseline and at 2 years postoperatively. The accuracy of the system models were evaluated in terms of mean square error (MSE) and mean absolute percentage error (MAPE). A global sensitivity analysis was also performed to assess the relative significance of input parameters in the system model and to rank the variables in order of importance. Compared to the LR model, the ANN model generally had smaller MSE and MAPE values in both the training and testing datasets. Most ANN models had MAPE values ranging from 4.70 to 19.96 %, and most had high prediction accuracy. The ANN model also outperformed the LR model in terms of prediction accuracy. According to global sensitivity analysis, pre-operative functional status was the best predictor of QOL after surgery. Compared with the conventional LR model, the ANN model in the study was more accurate for predicting patient-reported QOL and had higher overall performance indices. Further refinements are expected to obtain sufficient performance improvements for its routine use in clinical practice as an adjunctive decision-making tool.

Introduction: In 2006, the Association of American Medical Colleges (AAMC) issued a recommendation that medical schools increase the supply of physicians by 30% to meet the patient needs of the new millennium. Objective: To provide financial analysis of the cost of increasing class size. Methods: To determine the financial consequences of increasing medical student enrollment and in the absence of nationally published cost data for medical schools, adjusted secondary revenue data was analyzed using AAMC and Liaison Committee on Medical Education (LCME) financial data from 2009. Linear regression analysis was used to determine average fixed costs and variable cost per student in USD. Results: In USD, $62,877 represents the best point estimate of the annual variable cost of educating a medical student. Conclusion: Comparing this cost to current tuitions and fees of LCME-accredited medical schools suggests that revenues other than tuition are needed to cover increases in class size. Tuition and fees revenue from increasing enrollment will not increase overall revenue to medical schools.

The objective was to investigate the effect of admission health status on hospital adverse events and added costs. Secondary data were from merged administrative and clinical sources for Mayo Clinic Rochester, Minnesota hospital discharges in 2005 (N = 60,599). This was a retrospective cross-sectional study of the effect of demographics, diagnosis group, comorbidity, and admission illness severity on adverse events, incremental costs, and length of stay (LOS) using the Agency for Healthcare Research and Quality Patient Safety Indicators and provider-reported events with harm. Estimates are derived from generalized linear models. Admission severity increased the likelihood of all types of adverse events (7.2% per unit acute physiology score for any event); 7 specific comorbidities were associated with increased events and 2 with decreased events. High admission severity increased incremental costs and LOS. Selected comorbidities increased incremental LOS but had no significant effect on incremental costs. Adverse event reporting should incorporate comorbidity and admission severity. Reimbursement incentives to improve patient safety should consider adjustment for admission health status.

Board accountability for quality and patient safety is widely accepted but the science for how to measure it is immature, and differences between measuring performance, identifying hazards, and monitoring progress are often misunderstood. Hospital leaders often provide scorecards to assist boards with their oversight role yet, in the absence of national standards, little evidence exists regarding which measures are valid and useful to boards to assess quality improvement. The authors describe results of a cross-sectional board study, identifying the measures used to monitor quality. The measures varied widely and many were of uncertain validity, generally identifying hazards rather than measuring rates. This article identifies some important policy implications regarding boards' oversight of quality and acknowledges existing limits to how we can measure quality and safety progress on the national or hospital level. If boards and their hospitals are to monitor progress in improving quality, they need more valid outcome measures.

Purpose: To analyze longitudinal changes in each subscale of a quality of life (QOL) measure and to explore their relationships to effective QOL predictors in breast cancer surgery patients. Patients and methods: This prospective study analyzed 172 patients at two tertiary academic hospitals. All patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its supplementary breast cancer measure (QLQ-BR23) at baseline and at 1 and 2 years postoperatively. The 95% confidence intervals for differences in responsiveness estimates were derived by bootstrap estimation. Scores derived by these instruments were interpreted by generalized estimating equation (GEE) before and after surgery. Results: A 2-year follow-up survey of the examined population revealed significant (P < 0.05) improvement in each QOL subscale. In both postoperative surveys, effect size was largest in the QLQ subscales for patients who had received mastectomy with reconstruction and lowest in those who had received modified radical mastectomy. After adjusting for time effects and baseline predictors, GEE approaches revealed the following explanatory variables for QOL: time, type of surgical procedure, age, chemotherapy, radiotherapy, hormone therapy, and preoperative functional status. Conclusions: When evaluating QOL after breast cancer surgery, several factors other than the surgery itself should be considered. Patients should also be advised that their postoperative QOL might depend not only on the success of their operations, but also on their preoperative functional status.

This article presents a framework for the analysis of the development of gerontology since 1945. Three distinct historical periods and several forces that have shaped the field are examined. These forces reside in the political, economic, sociocultural, technological, and knowledge realms of society. An analysis of the continuities and discontinuities over time provides a contrast between the historical periods identified. Despite the ideology of a continuous linear disciplinary progression, we find that discontinuities have been increasingly significant in shaping the experience of aging. Yet the field of gerontology lags in reflecting many of these changes. This incongruity calls the field to reassess its paradigmatic foundations and the empirical and theoretical work conducted within them. The implications for the disciplines and practice of gerontology are explored through a review of C. Wright Mills' contribution to a revival of the “gerontological imagination.”

This study applied the generalised estimating equations (GEE) in a large-scale prospective cohort study of predictors of health-related quality of life (HRQoL) in a Taiwan population. The study population included all patients who had undergone primary total hip replacement (THR) performed between March 1998 and December 2002 by either of two orthopaedic surgeons in two hospitals. The SF-36 was used in pre- and postoperative assessments of 335 patients. Young age, male gender, minimal comorbidity, use of epidural anaesthesia, lack of readmission within the previous 30 days, and higher preoperative functional status were positively associated with HRQoL (P

The voluntary hospital trustee has traditionally seen issues of medical care, including those of patient safety, as falling within the delegated sphere of the medical staff. This customary distancing of the trustee from direct involvement in patient safety issues is now challenged by unprecedented scrutiny of hospital safety results through voluntary disclosure or mandatory public reporting. This new climate, fostered by the Institute of Medicine's To Err is Human and the Institute for Healthcare Improvement's 100,000 Lives campaign, has complicated the role of the trustee in satisfying the traditional “prudent person” test for meeting fiduciary obligation as the trustee's breadth of involvement expands. Viewed theoretically, Mintzberg models the hospital as a case of a professional bureaucracy, in which the professional staff is responsible for standard setting and regulation. This traditional role of the professional staff is potentially assumed by others lacking technical background. Trustees are now asked to examine reports identifying physician compliance in attaining safety standards without education in the practice supporting those standards. Physician board members, whose numbers have increased in the past decade, are often sought to take the lead on interpretation of patient safety standards and results. The very public nature of patient safety reporting and its reflection on the reputation of the organization for which the trustee is ultimately accountable create a new level of tension and workload that challenges the dominant voluntary model of trusteeship in the United States health system.

Innovation in health administration education stimulates administrators and faculty to identify unmet educational needs within the health sector. In 1997, the inaugural class of the Master of Medical Management (MMM) at Tulane University graduated, signaling an individual achievement for all graduates and an accomplishment in innovation and collaboration in health administration education. Tulane University, in partnership with The American College of Physician Executives (ACPE), designed a unique health administration degree to meet the distinctive needs of physicians serving in executive and managerial roles or seeking to serve in such roles in the future. Since 1997, there are nearly 700 MMM graduates who hail from Carnegie Mellon, Tulane University, and the University of Southern California. ACPE administered a survey to 500 MMM alumni in the fall of 2005. The response rate was 47% (235 of 500). The findings from this survey describe the reasons why physicians decided to enroll in the MMM, their experiences as MMM students, and their perceptions of how the MMM had an impact on their careers. Moreover, in this article, recommendations are offered related to the design and delivery of innovative educational programs for emerging disciplines within the health sector.

Context: Many attempts to identify hospital complications rely on secondary diagnoses from billing data. To be meaningful, diagnosis codes must distinguish between diagnoses after admission and those existing before admission. Objective: To assess the influence of diagnoses at admission on patient safety, comorbidity, severity measures, and case mix groupings for Medicare reimbursement. Design: Cross-sectional association of various diagnosis-based clinical and performance measures with and without diagnosis present on admission. Setting: Hospital discharges from Mayo Clinic Rochester hospitals in 2005 (N = 60,599). Patients: All hospital inpatients including surgical, medical, pediatric, maternity, psychiatric, and rehabilitation patients. About 33% of patients traveled more than 120 miles for care. Main Outcome Measures: Hospital patient safety indicators, comorbidity, severity, and case mix measures with and without diagnoses present at admission. Results: Over 90% of all diagnoses were present at admission whereas 27.1% of all inpatients had a secondary diagnosis coded in-hospital. About one-third of discharges with a safety indicator were flagged because of a diagnosis already present at admission, more likely among referral patients. In contrast, 87% of postoperative hemorrhage, 22% of postoperative hip fractures, and 54% of foreign bodies left in wounds were coded as in-hospital conditions. Severity changes during hospitalization were observed in less than 8% of discharges. Slightly over 3% of discharges were assigned to higher weight diagnosis-related groups based on an in-hospital complication. Conclusions: In general, many patient safety indicators do not reliably identify adverse hospital events, especially when applied to academic referral centers. Except as noted, conditions recorded after admission have minimal impact on comorbidity and severity measures or on Medicare reimbursement.

OBJECTIVE Attempts to provide information to consumers about patient safety on specific hospitals have conflicted with organization self-perceptions and led to confusion among the general public. This article presents organizational theory framework and criteria to classify organizations as single versus multiple reporting entities. PARTICIPANTS AND METHODS Operational definitions are presented. A case study comparing institutions both within and across state boundaries in the Mayo Clinic Health System is used to demonstrate their utility. The study includes analysis of an employee survey on employee satisfaction and patient safety climate in 2004 among nurses and physicians at the 2 Mayo Clinic hospitals in Rochester, Minn. RESULTS AND CONCLUSIONS The criteria for a single organization are more strongly supported for the Mayo Clinic hospitals located in the same city than for hospitals in the same system but separated geographically. Although there is debate about the measurement of organizational culture, employee surveys provide some evidence of a commonality across hospitals in the same city. The case study comparing institutions both within and across state boundaries in the Mayo Clinic Health System demonstrate the utility of the proposed criteria.

Great governance is an effective and efficient process to develop policies that set the strategic directions for the healthcare enterprise, and then help assure that resources are assembled and allocated for the successful implementation of the plans, in compliance with the ethical and regulatory framework of the industry. Given the growing legal and political emphasis on governance, it is crucial that undergraduate and graduate health administration programs adequately prepare students in the fundamental aspects of governance. This paper will present the ten building blocks of effective governance as well as other theories and frameworks applicable to teaching governance in a healthcare management program.

Today's competitive health care markets demand innovation and risk taking on the part of organizations. However, increased government regulation and stiffer penalties enacted in the wake of recent high-profile corporate scandals and the resulting Sarbanes–Oxley legislation, may render boards less willing to undertake entrepreneurial ventures. This article extends the typology of corporate entrepreneurship (CE) developed by Covin and Miles (1999) by extending the CE types to address governance activities in the health care sector. Four case studies are presented that illustrate each of the typology's forms. In addition, the implications of the typology for health care executives and trustees are discussed and areas for future research are recommended.

The objective of this study was to examine and predict the time trend of health-related quality of life (HRQoL) after total hip replacement (THR). A total of 383 patients receiving primary THR at two medical centers in Taiwan during 1997 to 2000 were enrolled for the study. Face-to-face interviews were conducted by using physician-rated Harris hip score and patient-reported short-form 36-item health survey (SF-36) immediately before the surgery and at 3, 6, 12, 24, and 60 months after surgery. Data analysed by piecewise linear regression revealed remarkable improvements in HRQoL dimensions at the third month after surgery and kept improving until the threshold level of from 39 months to 81 months, at which it reached a plateau. Role limitations due to physical and emotional problems and social functioning after surgery saw the most remarkable improvements, which appear to be related to improvements in functioning in many other dimensions of health. Such interdependence of the dimensions should be examined carefully to see if improvements in social roles can help improve the overall HRQoL in a more effective manner. The results should be applicable to other hospitals in Taiwan and in other countries with similar social and cultural practices.

Changes in the organization, financing, and delivery of health care services have prompted medical school leaders to search for new organizational models for linking medical schools, faculty practice groups, affiliated hospitals, and insurers-models that better meet the contemporary challenges of governance and decision making in academic medicine. However, medical school leaders have relatively little information about the range of organizational models that could be adopted, the extent to which particular organizational models are actually used, the conditions under which different organizational models are appropriate, and the ramifications of different organizational models for the academic mission. In this article, the authors offer a typology of eight organizational models that medical school leaders might use to understand and manage their relationships with physicians, hospitals, and other components of clinical delivery systems needed to support and fulfill the academic mission. In addition to illustrating the models with specific examples from the field, the authors speculate about their prevalence, the conditions that favor one over another, and the benefits and drawbacks of each for medical schools. To conclude, they discuss how medical school and clinical enterprise leaders could use the organizational typology to help them develop strategy and manage relationships with each other and their other partners.

This study compares the perspectives of eighteen managed care executives and twenty-four faculty practice executives on critical policy issues related to the managed care marketplace. Market sites studied in 1994 included four major metropolitan areas: Minneapolis–St. Paul, Los Angeles, Philadelphia, and Atlanta. These markets were selected as being representative of communities with descending degrees of managed care involvement, but with significant market activity. Study participants from both managed care systems and faculty practices examined five policy issues: (1) the importance of including academic medical centers in current and future health care plans for marketing purposes; (2) the provision of clinical services that are unique to the academic medical center, that is, unavailable elsewhere in the community; (3) the degree of financial supplement that employers might pay for including an academic medical center; (4) future restructuring of organizations to sustain the educational mission of academic faculty within a viable delivery system; (5) satisfaction of managed care providers with graduates of academic medical centers, as measured by the clinical skills of graduate physicians. The study findings showed little support among managed care plans for paying supplements to include faculty practices in a health care network. Most study participants from managed care systems and academic faculty practices identified limited competencies that are unique to academic centers. Moreover, managed care organizations were only willing to undertake limited restructuring at best to include faculty practices within their networks. General concern about the preparation of resident physicians (especially those in primary care disciplines) for practice within contemporary managed care organizations existed among managed care informants. The results of the study indicate that as traditional funding sources for medical education are reduced, schools require greater integration with managed care plans to enable academic medical centers and their faculties to continue promoting clinical enterprise.

e15130 Background: We examined whether primary androgen deprivation therapy (PADT), as compared to radical prostatectomy (RP), was associated with cardiovascular disease and death. Methods: Male patients with localized prostate cancer were identified in the SEER-Medicare (01/1998-12/2007). PADT patients were matched to the RP patients via propensity score. Cardiovascular risks ((i.e., ischemic heart disease (IHD), congestive heart failure (CHF), or cerebrovascular disease) were examined by Cox (PH) model; cardiovascular death by Fine & Gray competing risk. Important independent variables were controlled for. Results: The baseline variables were comparable. For the sample without cardiovascular disease (CVD) history, significantly increased risks for IHD, CHF, and aggregate risk of CVD were found in PADT group (all p-values 0.05); for the sample with CVD history, all the risks aforementioned were significantly increased in PADT group (all p-values

Background This study analyzed the likelihood of less-urgent emergency department (ED) visits among type 2 diabetic patients receiving care under a diabetes disease management (DM) program offered by the Louisiana State University Health Care Services Division (LSU HCSD). Methods All ED and outpatient clinic visits made by 6,412 type 2 diabetic patients from 1999 to 2006 were extracted from the LSU HCSD Disease Management (DM) Evaluation Database. Patient ED visits were classified as either urgent or less-urgent, and the likelihood of a less-urgent ED visit was compared with outpatient clinic visits using the Generalized Estimating Equation methodology for binary response to time-dependent variables. Results Patients who adhered to regular clinic visit schedules dictated by the DM program were less likely to use the ED for less urgent care with odds ratio of 0.1585. Insured patients had 1.13 to 1.70 greater odds of a less-urgent ED visit than those who were uninsured. Patients with better-managed glycated hemoglobin (A1c or HbA1c) levels were 82 times less likely to use less-urgent ED visits. Furthermore, being older, Caucasian, or a longer participant in the DM program had a modestly lower likelihood of less-urgent ED visits. The patient's Charlson Comorbidity Index (CCI), gender, prior hospitalization, and the admitting facility showed no effect. Conclusion Patients adhering to the DM visit guidelines were less likely to use the ED for less-urgent problems. Maintaining normal A1c levels for their diabetes also has the positive impact to reduce less-urgent ED usages. It suggests that successful DM programs may reduce inappropriate ED use. In contrast to expectations, uninsured patients were less likely to use the ED for less-urgent care. Patients in the DM program with Medicaid coverage were 1.3 times more likely to seek care in the ED for non-emergencies while commercially insured patients were nearly 1.7 times more likely to do so. Further research to understand inappropriate ED use among insured patients is needed. We suggest providing visit reminders, a call centre, or case managers to reduce the likelihood of less-urgent ED visit use among DM patients. By reducing the likelihood of unnecessary ED visits, successful DM programs can improve patient care.

The conflict between the elderly and organized medicine over "mandatory assignment" and "balance billing" is a significant public policy issue. Considerable ideological importance has been attached to this conflict by both sides, despite the relatively modest proportion of total revenue for physician services received through balance billing in payment for care of Medicare beneficiaries. The positions of these two coalitions are examined as well as the efforts of the Physician Payment Review Commission (PPRC) to craft a public policy response. Three alternative resolutions--those adopted by Congress in 1989 on the recommendation of the PPRC, the Canadian solution, and actions taken on a state level--are then contrasted. The concentrated impact on the elderly of balance billing practices is considered as a problem, especially for elderly of limited income and resources. Justification of the practice is typically provided by the profession on the ideological grounds of preservation of professional autonomy rather than economic gain, which also reflects the current relatively limited use of balance billing; a significant majority of all claims submitted in the United States are now assigned to physicians. A continuation of the gradualist strategy of the PPRC is endorsed as the most appropriate short-range solution to these problems, which diminish in significance with a more comprehensive national health financing scheme.

This study was designed to compare the effectiveness of stroke rehabilitation therapy in a specialized Stroke Unit with that provided on the medical service of a general hospital (Rhode Island Hospital). The 8-bed Stroke Unit is staffed by a multidisciplinary team, and a weekly conference is held for evaluation and planning. On the basis of data obtained from the hospital records, two groups of patients were studied: 224 who were treated in the Stroke Unit, and 110 who were evaluated and approved for admission to the Unit but were not accommodated. A rigid “first come, first served” policy for admission to the Unit was observed. Hypothesis testing was performed with reference to the patient's medical condition, socioeconomic status, demographic characteristics, and difficulties during hospital stay to determine whether the groups were comparable. A patient was considered to have improved if his condition decreased in severity between the time of admission to therapy and the time of discharge. Severity was rated as: mild (level one), moderate (level two), severe (level three), and profound (level four). No significant difference in rehabilitation results was found between the two treatment systems at severity levels two (moderate) and four (profound). However, the Stroke Unit attained significantly better results with level-three patients (severe stroke). This group received more sessions of physical therapy and remained in the hospital longer than did the level-three patients treated on the general medical service. Physicians referred patients selectively to the Stroke Unit, although the Unit had no policy of screening patients for admission, and this may have had some influence on the achievement of better results with level-three patients. Level-four patients did not do well in either setting.

A nurselphysician joint practice council, patterned after the activities and recommendations of the National Joint Practice Commission, was developed at a community hospital to provide a forum for nurse-physician dialogue regarding roles and practice issues. Clear objectives, good communications. utilization of resource persons, and equal physician and nurse representation are critical elements of the council's success. In operation, the council's focus is evolving from conflict resolution to a medium for planning and implementing change.
