The Canadian Adverse Events Study: the incidence of adverse events among hospital patients in Canada

Background: Research into adverse events (AEs) has highlighted the need to improve patient safety. AEs are unintended injuries or complications resulting in death, disability or prolonged hospital stay that arise from health care management. We estimated the incidence of AEs among patients in Canadian acute care hospitals. Methods: We randomly selected 1 teaching, 1 large community and 2 small community hospitals in each of 5 provinces (British Columbia, Alberta, Ontario, Quebec and Nova Scotia) and reviewed a random sample of charts for nonpsychiatric, nonobstetric adult patients in each hospital for the fiscal year 2000. Trained reviewers screened all eligible charts, and physicians reviewed the positively screened charts to identify AEs and determine their preventability. Results: At least 1 screening criterion was identified in 1527 (40.8%) of 3745 charts. The physician reviewers identified AEs in 255 of the charts. After adjustment for the sampling strategy, the AE rate was 7.5 per 100 hospital admissions (95% confidence interval [CI] 5.7– 9.3). Among the patients with AEs, events judged to be preventable occurred in 36.9% (95% CI 32.0%–41.8%) and death in 20.8% (95% CI 7.8%–33.8%). Physician reviewers estimated that 1521 additional hospital days were associated with AEs. Although men and women experienced equal rates of AEs, patients who had AEs were significantly older than those who did not (mean age [and standard deviation] 64.9 [16.7] v. 62.0 [18.4] years; p = 0.016). Interpretation: The overall incidence rate of AEs of 7.5% in our study suggests that, of the almost 2.5 million annual hospital admissions in Canada similar to the type studied, about 185 000 are associated with an AE and close to 70 000 of these are potentially preventable.

Progressive Independence in Clinical Training: A Tradition Worth Defending?

Background Progressive independence is a traditional premise of clinical training. Recently, issues such as managed care, work hours limitation, and patient safety have begun to impact the degree of autonomy afforded to clinical trainees. This article reviews empirical evidence and theory pertaining to the role of progressive autonomy in clinical learning. Method A computerized literature search was performed using Medline, PsycINFO, Social Sciences Citation Index, and Educational Resources Information Center. This article presents a synthetic review of relevant empirical and theoretical concepts from the domains of medicine, psychology, education, kinesiology, and sociology. Results The clinical psychology and medical education literatures provide evidence that clinical trainees act more independently as their training progresses, but have not yet evaluated the educational efficacy of providing progressive independence, or the consequences of failing to do so. The expertise and motor learning literatures provide some theoretical evidence (as yet untested in complex clinical environments) that the provision of too much guidance or feedback to trainees could be educationally detrimental in the long term. The sociology literature provides insight into the cultural values underlying the behavior of clinical teachers and trainees relating to issues of supervision and independence. Conclusions There is limited empirical support for the current model of progressive independence in clinical learning; however, diverse theoretical perspectives raise concern about the potential educational consequences of eroding progressive independence. These perspectives could inform future research programs that would create a creative and effective response to the social and economic forces impacting clinical education.

Preserving professional credibility: grounded theory study of medical trainees’ requests for clinical support

Objective To develop a conceptual framework of the influences on medical trainees’ decisions regarding requests for clinical support from a supervisor. Design Phase 1: members of teaching teams in internal and emergency medicine were observed during regular clinical activities (216 hours) and subsequently completed brief interviews. Phase 2: 36 in depth interviews were conducted using videotaped vignettes to probe tacit influences on decisions to request support. Data collection and analysis used grounded theory methods. Setting Three teaching hospitals in an urban setting in Canada. Participants 124 members of teaching teams on general internal medicine wards and in the emergency department, comprising 31 attending physicians, 57 junior and senior residents, 28 medical students, and eight nurses. Purposeful sampling to saturation was conducted. Results Trainees’ decisions about whether or not to seek clinical support were influenced by three issues: the clinical question (clinical importance, scope of practice), supervisor factors (availability, approachability), and trainee factors (skill, desire for independence, evaluation). Trainees perceived that requesting frequent/inappropriate support threatened their credibility and used rhetorical strategies to preserve credibility. These strategies included building a case for the importance of requests, saving requests for opportune moments, making a plan before requesting support, and targeting requests to specific team members. Conclusions Trainees consider not only clinical implications but also professional credibility when requesting support from clinical supervisors. Exposing the complexity of this process provides the opportunity to make changes to training programmes to promote timely supervision and provides a framework for further exploration of the impact of clinical training on quality of care of patients.

Nurse staffing models as predictors of patient outcomes.

Background. Little research has been conducted that examined the intended effects of nursing care on clinical outcomes. Objective. The objective of this study was to evaluate the impact of different nurse staffing models on the patient outcomes of functional status, pain control, and patient satisfaction with nursing care. Research Design. A repeated-measures study was conducted in all 19 teaching hospitals in Ontario, Canada. Subjects. The sample comprised hospitals and adult medical–surgical and obstetric inpatients within those hospitals. Measures. The patient’s functional health outcomes were assessed with the Functional Independence Measure (FIM) and the Medical Outcome Study SF-36. Pain was assessed with the Brief Pain Inventory and patient perceptions of nursing care were measured with the nursing care quality subscale of the Patient Judgment of Hospital Quality Questionnaire. Results. The proportion of regulated nursing staff on the unit was associated with better FIM scores and better social function scores at hospital discharge. In addition, a mix of staff that included RNs and unregulated workers was associated with better pain outcomes at discharge than a mix that involved RNs/RPNs and unregulated workers. Finally, patients were more satisfied with their obstetric nursing care on units where there was a higher proportion of regulated staff. Conclusions. The results of this study suggest that a higher proportion of RNs/RPNs on inpatient units in Ontario teaching hospitals is associated with better clinical outcomes at the time of hospital discharge.

Point-of-care Assessment of Medical Trainee Competence for Independent Clinical Work

Background Clinical supervisors make frequent assessments of medical trainees’ competence so they can provide appropriate opportunities for trainees to experience clinical independence. This study explored context-specific assessments of trainees’ competence for independent clinical work. Method In Phase One, 88 teaching team members from internal and emergency medicine were observed during clinical activities (216 hours), and 65 participants completed brief interviews. In Phase Two, 36 in-depth interviews were conducted using video vignettes. Data collection and analysis employed grounded theory methodology. Results Supervisors’ assessments of trainee trustworthiness for independent clinical work involved consideration of four dimensions: knowledge/skill, discernment of limitations, truthfulness, and conscientiousness. Supervisors’ reliance on language cues as a source of trustworthiness data was revealed. Conclusions This study provides an initial exploration of context-specific competence assessments, which affect both patient safety and education, and provides a novel framework for study of the links between language use and competence.

Quantification of the Hawthorne effect in hand hygiene compliance monitoring using an electronic monitoring system: a retrospective cohort study

Background The Hawthorne effect, or behaviour change due to awareness of being observed, is assumed to inflate hand hygiene compliance rates as measured by direct observation but there are limited data to support this. Objective To determine whether the presence of hand hygiene auditors was associated with an increase in hand hygiene events as measured by a real-time location system (RTLS). Methods The RTLS recorded all uses of alcohol-based hand rub and soap for 8 months in two units in an academic acute care hospital. The RTLS also tracked the movement of hospital hand hygiene auditors. Rates of hand hygiene events per dispenser per hour as measured by the RTLS were compared for dispensers within sight of auditors and those not exposed to auditors. Results The hand hygiene event rate in dispensers visible to auditors (3.75/dispenser/h) was significantly higher than in dispensers not visible to the auditors at the same time (1.48; p=0.001) and in the same dispensers during the week prior (1.07; p<0.001). The rate increased significantly when auditors were present compared with 1–5 min prior to the auditors’ arrival (1.50; p=0.009). There were no significant changes inside patient rooms. Conclusions Hand hygiene event rates were approximately threefold higher in hallways within eyesight of an auditor compared with when no auditor was visible and the increase occurred after the auditors’ arrival. This is consistent with the existence of a Hawthorne effect localised to areas where the auditor is visible and calls into question the accuracy of publicly reported hospital hand hygiene compliance rates.

'It's a cultural expectation...' The pressure on medical trainees to work independently in clinical practice.

Context  Medical trainees demonstrate a reluctance to ask for help unless they believe it is absolutely necessary, a situation which could impact on the safety of patients. This study aimed to develop a theoretical exploration of the pressure on medical trainees to be independent and to generate theory‐based approaches to the implications for patient safety of this pressure towards independent working.

Silence, Power and Communication in the Operating Room

Title. Silence, power and communication in the operating room Aim This paper is a report of a study conducted to explore whether a 1- to 3-minute preoperative interprofessional team briefing with a structured checklist was an effective way to support communication in the operating room. Background Previous research suggests that nurses often feel constrained in their ability to communicate with physicians. Previous research on silence and power suggests that silence is not only a reflection of powerlessness or passivity, and that silence and speech are not opposites, but closely interrelated. Methods We conducted a retrospective study of silences observed in communication between nurses and surgeons in a multi-site observational study of interprofessional communication in the operating room. Over 700 surgical procedures were observed from 2005–2007. Instances of communication characterized by unresolved or unarticulated issues were identified in field notes and analysed from a critical ethnography perspective. Findings We identified three forms of recurring ‘silences’: absence of communication; not responding to queries or requests; and speaking quietly. These silences may be defensive or strategic, and they may be influenced by larger institutional and structural power dynamics as well as by the immediate situational context. Conclusions There is no single answer to the question of why ‘nobody said anything’. Exploring silences in relation to power suggests that there are multiple and complex ways that constrained communication is produced in the operating room, which are essential to understand in order to improve interprofessional communication and collaboration.

A Balanced Scorecard for Canadian Hospitals

Managing a health care organization on the basis of one set of information alone (e.g., financial information) does not give a full view of the impact of changes on the organization. A balanced scorecard approach can provide management with a comprehensive framework that turns an organizations strategic objectives into a coherent set of performance measures. This approach has been used extensively in industry, but seldom in health care organizations. By developing a scorecard approach, these organizations could obtain feedback providing a balanced view of organizational performance, letting them see if improvements in one area may have been achieved at the expense of another. It also demands that managers translate their general mission statement on customer service into specific measures that reflect the factors that really matter to customers.

Downsizing, reengineering, and restructuring: long-term implications for healthcare organizations.

Summary This article provides a framework for analyzing how downsizing and reengineering have affected healthcare organizations. These approaches are reviewed, and key tools that have been used, such as across‐the‐board cuts, reorganizing, and redesigning, are described. Examples are drawn from healthcare as well as other business sectors. The consequences of cost reduction strategies for an organizations performance in terms of costs, quality of services, and satisfaction of consumers and employees are explored. The case is made that an organizations context‐that is, its culture, level of trust, and leadership‐is an important factor that influences the effect of cost‐cutting strategies. Characteristics of organizations where downsizing has a better chance of succeeding also are described.
