Organization and Representation of Patient Safety Data: Current Status and Issues around Generalizability and Scalability

Recent reports have identified medical errors as a significant cause of morbidity and mortality among patients. A variety of approaches have been implemented to identify errors and their causes. These approaches include retrospective reporting and investigation of errors and adverse events and prospective analyses for identifying hazardous situations. The above approaches, along with other sources, contribute to data that are used to analyze patient safety risks. A variety of data structures and terminologies have been created to represent the information contained in these sources of patient safety data. Whereas many representations may be well suited to the particular safety application for which they were developed, such application-specific and often organization-specific representations limit the sharability of patient safety data. The result is that aggregation and comparison of safety data across organizations, practice domains, and applications is difficult at best. A common reference data model and a broadly applicable terminology for patient safety data are needed to aggregate safety data at the regional and national level and conduct large-scale studies of patient safety risks and interventions.

Neurologic patient safety: An in-depth study of malpractice claims

This in-depth study of neurologic malpractice claims indicated authentic, preventable patient harm in 24 of 42 cases, enabling comparison with larger but administratively abstracted summary reports. Principal findings included the common occurrence of outpatient events, lapses in communication with patients and other providers, the need for follow-through by the consultant neurologist even when not primarily responsible, the frequency of diagnostic errors, and pitfalls associated with imaging.

Morphing as a means of generating variation in visual medical teaching materials

In computer-based medical education, there is frequently a need to present students with pictorial data representative of the natural variation associated with disease presentations as well as the progression of disease within an individual. Because of the difficulty in acquiring such data, image acquisition is often the most resource-intensive phase of multimedia courseware development. In light of the resource demands associated with image content, many courseware designers do not make opportune use of image data, but rely instead upon text descriptions to provide variation in content. The resulting lack of adequate pictorial content often lessens the overall impact of the courseware. To overcome constraints imposed by the difficulty in acquiring pictorial content of sufficient richness, a methodology of generating variation in visual teaching materials has been developed through the use of morphing. These techniques have general applicability in creating variation in pictorial teaching materials in a variety of image-intensive domains.

Four-year impact of an alert notification system on closed-loop communication of critical test results.

OBJECTIVE One of the patient safety goals proposed by the Joint Commission urges hospitals to develop a policy for communicating critical test results and to measure adherence to that policy. We evaluated the impact of an alert notification system on policy adherence for communicating critical imaging test results to referring providers and assessed system adoption over the first 4 years after implementation. MATERIALS AND METHODS This study was performed in a 753-bed academic medical center. The intervention, an automated alert notification system for critical results, was implemented in January 2010. The primary outcome was adherence to institutional policy for timely closed-loop communication of critical imaging results, and the secondary outcome was system adoption. Policy adherence was determined through manual review of a random sample of radiology reports from the first 4 years after the intervention (n = 37,604) compared with baseline outcomes 1 year before the intervention (n = 9430). Adoption was evaluated by quantifying the use of the system overall and the proportion of alerts that used noninterruptive communication as a percentage of all reports generated by 320 radiologists (n = 1,538,059). A statistical analysis of the trend at 6-month intervals over 4 years was performed using a chi-square trend test. RESULTS Adherence to the policy increased from 91.3% before the intervention to 95.0% after the intervention (p < 0.0001). There was a ninefold increase in the critical results communicated via the system (chi-square trend test, p < 0.0001). During the first 4 years after the intervention, 41,445 alerts (41% of the total number of alerts) used the systems noninterruptive process for communicating less urgent critical results, which was substantially unchanged over the 4 years postintervention, thus reducing unnecessary paging interruptions. CONCLUSION An automated alert notification system for communicating critical imaging results was successfully adopted and was associated with increased adherence to institutional policy for communicating critical test results and with reduced workflow interruptions.

Can 360-Degree Reviews Help Surgeons? Evaluation of Multisource Feedback for Surgeons in a Multi-Institutional Quality Improvement Project

BACKGROUND Medical organizations have increased interest in identifying and improving behaviors that threaten team performance and patient safety. Three hundred and sixty degree evaluations of surgeons were performed at 8 academically affiliated hospitals with a common Code of Excellence. We evaluate participant perceptions and make recommendations for future use. STUDY DESIGN Three hundred and eighty-five surgeons in a variety of specialties underwent 360-degree evaluations, with a median of 29 reviewers each (interquartile range 23 to 36). Beginning 6 months after evaluation, surgeons, department heads, and reviewers completed follow-up surveys evaluating accuracy of feedback, willingness to participate in repeat evaluations, and behavior change. RESULTS Survey response rate was 31% for surgeons (118 of 385), 59% for department heads (10 of 17), and 36% for reviewers (1,042 of 2,928). Eighty-seven percent of surgeons (95% CI, 75%-94%) agreed that reviewers provided accurate feedback. Similarly, 80% of department heads believed the feedback accurately reflected performance of surgeons within their department. Sixty percent of surgeon respondents (95% CI, 49%-75%) reported making changes to their practice based on feedback received. Seventy percent of reviewers (95% CI, 69%-74%) believed the evaluation process was valuable, with 82% (95% CI, 79%-84%) willing to participate in future 360-degree reviews. Thirty-two percent of reviewers (95% CI, 29%-35%) reported perceiving behavior change in surgeons. CONCLUSIONS Three hundred and sixty degree evaluations can provide a practical, systematic, and subjectively accurate assessment of surgeon performance without undue reviewer burden. The process was found to result in beneficial behavior change, according to surgeons and their coworkers.

Malpractice Risk in Ambulatory Settings An Increasing and Underrecognized Problem

F A GROUP OF PHYSICIANS WERE ASKED TO LIST THE SPEcialties of clinical medicine that carry the highest risk of malpractice, invariably the first responses would includeobstetrics/gynecology,anesthesia,andvarioussurgical specialties. These clinical domains are well recognized to carry risk and have done so for many years. The results of adverse events in these clinical fields tend to be catastrophic and historically have often resulted in highprofilelegalcases,coveredinthemediaandassociatedwith large indemnity payments. It is the rare clinician who will list a general internist or other noninterventional outpatient specialty in the list of high-risk physicians. This unrecognized risk, and the associated absence of risk management programs in ambulatory care settings across the country, is a cause for concern. ThearticlebyBishopandcolleagues 1 inthisissueofJAMA highlights an increasing risk of malpractice in the ambulatory area and makes some tentative initial steps to identify its causes. In this way, the study is a wake-up call for physicians who practice primarily in ambulatory settings and forphysiciansandadministratorswiththeabilitytosetpolicy for these areas. Bishop and colleagues 1 used data from the National Practitioner Data Bank (NPDB), which inventories payments madeonmalpracticeeventsnationally,eitherthroughsettlement or trial resolution. The NPDB also tracks disciplinary actions made against physicians at the state level. Although 71% of the events from 2005 to 2009, the period of the study, included in the database were related to disciplinary actions, there were more than 10000 malpractice payments registered each year, resulting in a large number for the analysis by Bishop et al. 1

Reducing risk with clinical decision support: a study of closed malpractice claims.

OBJECTIVE Identify clinical opportunities to intervene to prevent a malpractice event and determine the proportion of malpractice claims potentially preventable by clinical decision support (CDS). MATERIALS AND METHODS Cross-sectional review of closed malpractice claims over seven years from one malpractice insurance company and seven hospitals in the Boston area. For each event, clinical opportunities to intervene to avert the malpractice event and the presence or absence of CDS that might have a role in preventing the event, were assigned by a panel of expert raters. Compensation paid out to resolve a claim (indemnity), was associated with each CDS type. RESULTS Of the 477 closed malpractice cases, 359 (75.3%) were categorized as substantiated and 195 (54%) had at least one opportunity to intervene. Common opportunities to intervene related to performance of procedure, diagnosis, and fall prevention. We identified at least one CDS type for 63% of substantiated claims. The 41 CDS types identified included clinically significant test result alerting, diagnostic decision support and electronic tracking of instruments. Cases with at least one associated intervention accounted for

40.3 million (58.9%) of indemnity. DISCUSSION CDS systems and other forms of health information technology (HIT) are expected to improve quality of care, but their potential to mitigate risk had not previously been quantified. Our results suggest that, in addition to their known benefits for quality and safety, CDS systems within HIT have a potential role in decreasing malpractice payments. CONCLUSION More than half of malpractice events and over

The Impact of Incident Disclosure Behaviors on Medical Malpractice Claims

OBJECTIVES This paper describes verdicts in court involving injury-producing medical errors in Spain. DESIGN, SETTING AND PARTICIPANTS A descriptive analysis of 1041 closed court verdicts from Spain between January 2002 and December 2012. It was determined whether a medical error had occurred, and among those with medical error (n = 270), characteristics and results of litigation were analyzed. Data on litigation were obtained from the Thomson Reuters Aranzadi Westlaw databases. MAIN OUTCOME MEASURES All verdicts involving health system were reviewed and classified according to the presence of medical error. Among those, contributory factors, medical specialty involved, health impact (death, disability and severity) and results of litigation (resolution, time to verdict and economic compensations) were described. RESULTS Medical errors were involved in 25.9% of court verdicts. The cause of medical error was a diagnosis-related problem in 25.1% and surgical treatment in 22.2%, and Obstetrics-Gynecology was the most frequent involved specialty (21%). Most of them were of high severity (59.4%), one-third (32%) caused death. The average time interval between the occurrence of the error and the verdict was 7.8 years. The average indemnity payment was €239 505.24; the highest was psychiatry (€7 585 075.86) and the lowest was Emergency Medicine (€69 871.19). CONCLUSIONS This study indicates that in Spain medical errors are common among verdicts involving the health system, most of them causing high-severity adverse outcomes. The interval between the medical error and the verdict is excessive, and there is a wide range of economic compensation.
