Hospital organizational change and financial status: costs and outcomes of care in Philadelphia.

Two recent changes in Philadelphia-area hospital organizations are consolidation into systems and acquisition of 2 medical school hospitals by a for-profit chain. This study explored whether such consolidation and conversion affected costs and outcomes of care. The analysis included 1,617,581 discharges from 49 acute-care hospitals from 1997 to 1999. Analyses within and between medical school hospitals examined trends in discharges, case mix, length of stay, and mortality. The study addressed 2 questions: whether, as hospitals consolidate into medical school hospital-based systems, volume, severity, length of stay, and mortality increase in those hospitals; and whether for-profit conversion redistributes complex, high-cost admissions to nonprofit hospitals. The 2 medical school hospitals that became for-profit experienced decreases in volume and resource intensity, coupled at one with an increase in severity. However, these patterns were produced more by the system's financial instability than by consolidation or conversion.

Outpatient quality improvement in academic faculty practice plans: does it exist?

The purpose of this study was to (a) investigate the extent to which academic faculty practice plans (FPPs) are currently involved in ambulatory care quality improvement (QI), (b) describe the structure of QI initiatives at outpatient FPPs, and (c) delineate facilitators and barriers to development of FPP outpatient QI initiatives. Members of the Steering Committee of the Group Practice Council of the University HealthSystem Consortium (UHC), representing the leadership of 88 FPPs, were asked to respond to a 38-item Web-based questionnaire during February and March 2003. The survey elicited information on the organizational characteristics of FPPs, their current degree of engagement in outpatient QI activities, and factors driving interest and barriers impeding efforts to conduct outpatient QI initiatives. Descriptive statistics for all variables of interest were performed. Responses were received from 33 participants believed to represent at least 28 of the total 88 FPP members of the UHC. Nearly all respondents indicated that some types of outpatient QI initiatives were currently taking place in their FPP. However, only 12% of respondents met 4 or more of the 6 criteria deemed to be essential to having a robust outpatient QI program. Among key QI indicators, one third of respondents reported that their FPP had a separate and distinct outpatient quality committee, and some one fifth had a budget for outpatient QI or financial incentives for outpatient clinics to engage in QI (or both). The majority of respondents stated that at least some departments in their FPP were collecting quality data. Most respondents reported that patient safety and external demand for outpatient QI were the "more important" factors driving QI efforts, whereas lack of human resources and other resources were the "more significant" barriers hindering QI initiatives. The results of the study suggest that, although FPPs showed a strong interest in outpatient QI initiatives, FPPs' efforts are still in an infancy phase and lag far behind inpatient performance measurement activities. Without appropriate resources, it appears unlikely that FPPs will be able to move the agenda forward to develop a quality culture and robust program of self-assessment and improvement in the outpatient setting.

Factors related to physicians' adoption of electronic prescribing: results from a national survey.

Electronic prescribing (E-RX) is a component of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA). The objective of this study was to identify factors related to physicians' adoption of E-RX for outpatients. This study employed an electronic survey of US physicians who subscribe to the Physicians Online Internet service. Electronic prescribers were compared to traditional prescribers in terms of demographics, practice type and location, technology use, and beliefs about E-RX. A total of 1104 physicians responded, 19% of whom prescribed electronically. Electronic prescribers were more likely to be generalists practicing in academic or publicly funded centers, have fewer years in practice, and work in technology-equipped offices. They also held different beliefs versus traditional prescribers in terms of E-RX limitations and its potential to improve medication safety and prescribing efficiency. In addition to financial incentives established by MMA, adoption can be stimulated by improvements in the technology and on organizational commitment.

Clinical vignette-based surveys: a tool for assessing physician practice variation.

Clinical vignette-based surveys have been used for more than 30 years to measure variation in physicians' approaches to the diagnosis and treatment of patients with similar health problems. Vignettes offer advantages over medical record reviews, analysis of claims data, and standardized patients. A vignette-based survey can be completed more quickly than a record review or standardized patient program. Research has shown that vignette-based surveys produce better measures of quality of care than medical record reviews when used to measure differential diagnosis, selection of tests, and treatment decisions. Although standardized patients are preferred when measuring communication and physical examination skills, vignettes are more cost-effective than standardized patients when assessing clinical physicians' decision making. Vignettes offer better opportunities to isolate physicians' decision making and to control case-mix variation than do analyses of claims data sets. Clinical vignette-based surveys are simple and economical tools that can be used to characterize physicians' practice variation.

Interactive voice response reminder effects on preventive service utilization.

This study evaluated the effects of interactive voice response (IVR) system reminders to managed care organization (MCO) members to obtain mammograms, Papanicolaou (Pap) tests, and influenza immunizations. The MCO identified 3 member cohorts and sent IVR reminders to get preventive services. Analyses employed claims data to examine relationships between IVR reminders and preventive service use 5 to 9 months post-intervention among members without prior utilization. Multivariate logistic regressions controlling for age, gender (for influenza immunizations), and risk stratum confirmed hypothesized relationships between intervention and preventive services: mammograms, odds ratio (OR) = 1.263 (95% confidence interval [CI] = 1.104, 1.444); Pap tests, OR = 1.241 (1.107, 1.391); influenza immunizations, OR = 2.072 (1.665, 2.580). IVR reminders are associated with higher rates of mammograms, Pap tests, and influenza immunizations. Study limitations include unknown generalizability of results and possible self-selection. There is justification for more IVR interventions and research to enhance MCO members' preventive service utilization.

Health care provider use of private sector internal error-reporting systems.

The purpose of this study was to review the state of the art of private sector internal error-reporting systems and to begin to develop a classification system for comparing systems. Interviews were conducted to research and examine 9 systems currently on the market. Analysis resulted in the following observations: (1) 7 of the systems are stand-alone, while 2 are part of larger hospital information systems; (2) most of the systems have been in existence for less than 5 years; (3) acute care hospitals are the primary clients; (4) systems are capable of interfacing with other information systems and root-cause analysis programs; and (5) systems are browser based and accessible via the Internet and/or the provider's intranet. Additional studies are needed to determine the impact of these systems on health outcomes. However, one fact is clear: tracking incidents will not improve patient safety unless administrators close the feedback loop on quality.

Mandatory state-based error-reporting systems: current and future prospects.

The magnitude of medical errors documented in the 1999 Institute of Medicine report "To Err Is Human" encouraged health care leaders across the country to evaluate and improve current systems of care. To aid in this effort, the authors recommended and provided guidelines for establishing state-based mandatory error-reporting systems. This repository for medical errors would allow experts to categorize, trend, and analyze data, generating institutional responsibility and increasing knowledge about medical mistakes. To be effective, these systems must employ efficient data collection methods, techniques for analysis, and feedback mechanisms. They must also engage institutional leaders in fostering a culture of safety and encourage multidisciplinary collaboration to learn from mistakes and improve microsystem-level processes. A review of current systems reveals extreme variation across states in each of these areas. However, initial successes do exist, suggesting the true potential of these systems and the need for continued evaluation as systems progress in future efforts.

Development and evaluation of a 1-day interclerkship program for medical students on medical errors and patient safety.

Medical students need to be well informed about medical errors and patient safety. Pursuant to a needs assessment and pilot program, 229 third-year students participated in a 1-day program on patient safety including a plenary session and workshops. Attitudes and beliefs were measured by a survey at the beginning and end of the program. Completed surveys were returned by 124 (54%) students. Their level of agreement with 14 of 21 rating scale items changed in the expected direction. There were 7 items in which the students' baseline responses were already positive and did not change significantly. A 1-day program on patient safety in the third year of medical school can change students' attitudes and beliefs. There may be a subset of students needing closer attention. The findings provide evidence for the validity of the attitude survey and reinforce the effectiveness of interclerkship programs in medical schools.
