Adjusting Medicare Capitation Payments Using Prior Hospitalization Data, Arlene Ash, Frank Porell, Leonard Gruenberg, Eric Sawitz, Alexa Beiser

Frank Porell

The diagnostic cost group approach to a reimbursement model for health maintenance organizations is presented. Diagnostic information about previous hospitalizations is used to create empirically determined risk groups, using only diagnoses involving little or no discretion in the decision to hospitalize. Diagnostic cost group and other models (including Medicare's current formula and other prior-use models) are tested for their ability to predict future costs, using R2 values and new measures of predictive performance. The diagnostic cost group models perform relatively well with respect to a range of criteria, including administrative feasibility, resistance to provider manipulation, and statistical accuracy.

Patient Education About Anticoagulant Medication: Is Narrative Evidence Or Statistical Evidence More Effective?, Kathleen Mazor, Joann Baril, Elizabeth Dugan, Frederick Spencer, Pamela Burgwinkle, Jerry Gurwitz

Elizabeth Dugan

OBJECTIVE: To determine the relative impact of incorporating narrative evidence, statistical evidence or both into patient education about warfarin, a widely used oral anticoagulant medication.

METHODS: 600 patients receiving anticoagulant therapy were randomly assigned to view one of three versions of a video depicting a physician-patient encounter where anticoagulation treatment was discussed, or usual care (no video). The videos differed in whether the physician used narrative evidence (patient anecdotes), statistical evidence, or both to highlight key information. 317 patients completed both the baseline and post-test questionnaires. Questions assessed knowledge, beliefs and adherence to medication and laboratory monitoring regimens.

RESULTS: All …

Charles Weijer

This article is part of a series of papers examining ethical issues in cluster randomized trials (CRTs) in health research. In the introductory paper in this series, we set out six areas of inquiry that must be addressed if the cluster trial is to be set on a firm ethical foundation. This paper addresses the second of the questions posed, namely, from whom, when, and how must informed consent be obtained in CRTs in health research? The ethical principle of respect for persons implies that researchers are generally obligated to obtain the informed consent of research subjects. Aspects of CRT …

Talk, Trust And Time: A Longitudinal Study Evaluating Knowledge Translation And Exchange Processes For Research On Violence Against Women, C. Wathen, Shannon Sibbald, Susan Jack, Harriet Macmillan

Shannon L. Sibbald

BACKGROUND: Violence against women (VAW) is a major public health problem. Translation of VAW research to policy and practice is an area that remains understudied, but provides the opportunity to examine knowledge translation and exchange (KTE) processes in a complex, multi-stakeholder context. In a series of studies including two randomized trials, the McMaster University VAW Research Program studied one key research gap: evidence about the effectiveness of screening women for exposure to intimate partner violence. This project developed and evaluated KTE strategies to share research findings with policymakers, health and community service providers, and women's advocates. METHODS: A longitudinal cross-sectional …

Peter J. Huckfeldt

In the National Pilot Program on Payment Bundling, a subset of Medicare providers will receive a single payment for an episode of acute care in a hospital, followed by postacute care in a skilled nursing or rehabilitation facility, the patient’s home, or other appropriate setting. This article examines the promises and pitfalls of bundled payments and addresses two important design decisions for the pilot: which conditions to include, and how long an episode should be. Our analysis of Medicare data found that hip fracture and joint replacement are good conditions to include in the pilot because they exhibit strong potential …

Taiwanese American Identity In The U.S. Census. Taipei Times., Chiehwen Ed Hsu

Chiehwen Ed Hsu

The U.S. Census announced that close to a quarter million Taiwan expatriates self identified as 'Taiwanese' in the Census 2010, nearly doubling the figure from a decade ago, with most Taiwanese community so identified in the state of California, New York and Texas. Both politically and substantively significant, the statistic does not only suggest a concerted self identity of Taiwanese expatriates, but also signals an expanded health and social service needs of this growing community to be met. The growing number of self-identifying Taiwanese in the U.S. is politically important, as the increased constituents of Taiwanese Americans representing an even …

Only recently has knowledge management been receiving attention by the health care sector, in part due to the ever growing amount of information that health care practitioners must handle. It has become essential to develop a way to manage the information coming in to and going out of a health care organization. The purpose of this paper was to summarize previous studies from the business literature that explored specific knowledge management tools, with the aim of extracting lessons that could be applied in the health …

Opening The Industry Playbook: Myths And Truths In The Debate Over Bpa Regulation, Thomas Mcgarity, Rena Steinzor, Matthew Shudtz, Lena Pons

Rena I. Steinzor

For the last two decades, scientists have amassed evidence that bisphenol A (BPA) poses a threat to human health. Although scientists have targeted BPA as a public health concern, plastics industry lobbyists have attempted to thwart the efforts of federal, state, and local authorities to reduce exposure to BPA. This paper reviews the major arguments advanced by the plastics industry and debunks them as “myths” that public health officials must reject. The five topics covered include: the myth of scientific consensus on safety; the myth that only studies complying with “Good Laboratory Practices” guidelines are adequate for making regulatory decisions; …

Working Off The Record: Physicians' And Nurses' Transformations Of Electronic Patient Record-Based Patient Information, Lara Varpio, Catherine Schryer, Pascale Lehoux, Lorelei Lingard

Lorelei Lingard

BACKGROUND: Electronic patient records (EPRs) are increasingly being used in health care, but little is known about how EPR-based patient information is used in daily care activities, nor about its potential influence on novice training.

METHOD: Seventy-two physicians and nurses participated in an eight-month study on a single pediatric ward. Eighty hours of nonparticipant observations and 20 interviews were conducted. Data were analyzed using constructivist grounded theory and visual rhetoric.

RESULTS: Three main features of participant interactions with EPR-based information were identified: (1) EPR-based information was routinely transformed into paper documents; (2) these transformations were organized by profession-specific guiding principles; …

Techne Or Artful Science And The Genre Of Case Presentations In Healthcare Settings, Catherine Schryer, Lorelei Lingard, Marlee Spafford

Lorelei Lingard

This paper presents a qualitative study that investigated the role of case presentations in the socialization of medical and optometry students. Using the debate from classical rhetoric around the term techne (art or science), we observed that genre theory helps explain the way case presentations mediate the development of professional identity through the interaction of certain knowledge (techne 1), “savvy” knowledge (techne 2), and ethical reflection (phronesis). We noted that these mediated scenes of learning are necessary but problematic because they can lead students to yearn for certainty and to exclude outsiders (other healthcare providers, patients). Finally, our research challenges …

Look Who’S Talking: Teaching And Learning Using The Genre Of Medical Case Presentations, Marlee Spafford, Catherine Schryer, Marcellina Mian, Lorelei Lingard

Lorelei Lingard

In a pediatric teaching hospital, the authors examined 16 novice medical case presentations that were classified as instances of a hybrid apprenticeship genre. In contrast to strict school and workplace genres, an apprenticeship genre results from the sometimes competing activity systems of student education and patient care. The authors examined these novice case presentations for the amount and patterns of time devoted to student learning and expert teaching, the difficulties created for participants, the sometimes misunderstood implicit messages delivered by experts, and the opportunities to address educational objectives. This study offers professional communication researchers a model that combines quantitative and …

Error Or "Act Of God"? A Study Of Patients' And Operating Room Team Members' Perceptions Of Error Definition, Reporting, And Disclosure, Sherry Espin, Wendy Levinson, Glenn Regehr, G. Baker, Lorelei Lingard

Lorelei Lingard

BACKGROUND: Calls abound for a culture change in health care to improve patient safety. However, effective change cannot proceed without a clear understanding of perceptions and beliefs about error. In this study, we describe and compare operative team members' and patients' perceptions of error, reporting of error, and disclosure of error. METHODS: Thirty-nine interviews of team members (9 surgeons, 9 nurses, 10 anesthesiologists) and patients (11) were conducted at 2 teaching hospitals using 4 scenarios as prompts. Transcribed responses to open questions were analyzed by 2 researchers for recurrent themes using the grounded-theory method. Yes/no answers were compared across groups …

Factors Influencing Perioperative Nurses' Error Reporting Preferences, Sherry Espin, Glenn Regehr, Wendy Levinson, G. Baker, Christina Biancucci, Lorelei Lingard

Lorelei Lingard

To explore the influence of scope of practice and patient outcomes on error reporting, 13 nurses were interviewed after they reviewed four "error" scenarios ranging in both scope of practice and seriousness of outcome. Of 52 theoretical incidents, only 30 were identified as errors. The nurses indicated they would formally report errors for only eight of the incidents. For another 10 incidents, the nurses would have reported using an informal reporting system only. Qualitative analysis of the interviews revealed that perceived scope of practice influenced reporting preferences, and seriousness of outcome was only a secondary consideration. Selective error reporting and …

Tensions Influencing Operating Room Team Function: Does Institutional Context Make A Difference?, Lorelei Lingard, Stacey Garwood, Dan Poenaru

Lorelei Lingard

BACKGROUND: A recent study of operating room (OR) team communication in a large, urban hospital described recurrent tension catalysts and a preliminary theory of team members' interpretive processes. To determine to what extent these findings were transferable to other institutional contexts, we conducted a validation study in 2 small, academic hospitals in a mid-size city. METHODS: Eight focus groups and 8 interviews were conducted with 6 general surgeons, 22 OR nurses, 5 anaesthesiologists and 10 trainees. Observations of 10 surgeons and their team members were conducted over 4 months. Data were analysed by applying thematic codes derived from previous research …

'Talking The Talk': School And Workplace Genre Tension In Clerkship Case Presentations, Lorelei Lingard, C. Schryer, K. Garwood, M. Spafford

Lorelei Lingard

BACKGROUND: Socialisation into a community involves learning sanctioned ways of talking. This study investigates the case presentation genre as a site of socialisation into the clinical community of practice. METHODS: Sixteen oral case presentations and the teaching exchanges surrounding them (involving 11 students and 10 faculty members) were observed by paired researchers during inpatient paediatric medicine rounds. A total of 21 in-depth interviews were conducted with 11 students and 10 faculty. Both data sets were audio-recorded, transcribed and analysed for emergent themes and rhetorical strategies. RESULTS: Students emphasised case presentation as a school genre and described the ideal presentation as …

A Qualitative Study Examining Tensions In Interdoctor Telephone Consultations, Anupma Wadhwa, Lorelei Lingard

Lorelei Lingard

OBJECTIVE: Communication skills have gained increasing attention in medical education. Much of the existing literature and medical curricula addresses issues of doctor-patient communication. The critical importance of communication between health professionals, however, is now coming under the spotlight. The interdoctor telephone consultation is a common health care setting in which health professional communication skills are exercised. Breakdowns in this communication commonly occur and, surprisingly, this skill is not formally addressed in medical training. This study sought to clarify the communication issues that can occur during interdoctor telephone consultations in order to inform future educational initiatives in this domain. METHODS: Data …

What Healthcare Students Do With What They Don't Know: The Socializing Power Of 'Uncertainty' In The Case Presentation, Marlee Spafford, Catherine Schryer, Lorelei Lingard, Patricia Hrynchak

Lorelei Lingard

Healthcare students learn to manage clinical uncertainty amid the tensions that emerge between clinical omniscience and the 'truth for now' realities of the knowledge explosion in healthcare. The case presentation provides a portal to viewing the practitioner's ability to manage uncertainty. We examined the communicative features of uncertainty in 31 novice optometry case presentations and considered how these features contributed to the development of professional identity in optometry students. We also reflected on how these features compared with our earlier study of medical students' case presentations. Optometry students, like their counterparts in medicine, displayed a novice rhetoric of uncertainty that …

Forming Professional Identities On The Health Care Team: Discursive Constructions Of The 'Other' In The Operating Room, Lorelei Lingard, R. Reznick, I. Devito, S. Espin

Lorelei Lingard

BACKGROUND: Inter-professional health care teams represent the nucleus of both patient care and the clinical education of novices. Both activities depend upon the'talk' that team members use to interact with one another. This study explored team members' interpretations of tense team communications in the operating room (OR). METHODS: The study was conducted using 52 team members divided into 14 focus groups. Team members comprised 13 surgeons, 19 nurses, nine anaesthetists and 11 trainees. Both uni-disciplinary (n = 11) and multi-disciplinary (n = 3) formats were employed. All groups discussed three communication scenarios, derived from prior ethnographic research. Discussions were audio-recorded …

Junior Faculty Experiences With Informal Mentoring, Karen Leslie, Lorelei Lingard, Sarah Whyte

Lorelei Lingard

Mentoring is one way in which new faculty can acquire the skills needed for a successful academic career. Little is known about how informal mentoring is operationalized in an academic setting. This study had two main objectives: (1) to determine if junior faculty identify as having an informal mentor(s) and to describe their informal mentoring relationships; and (2) to identify the areas in which these faculty seek career assistance and advice. The study employed a grounded theory approach. Subjects were recruited from the clinical teaching faculty and were 3-7 years into their first faculty position. Theoretical sampling was employed in …
