Missed and delayed diagnoses in the ambulatory setting: a study of closed malpractice claims.

BACKGROUND: Although missed and delayed diagnoses have become an important patient safety concern, they remain largely unstudied, especially in the outpatient setting. OBJECTIVE: To develop a framework for investigating missed and delayed diagnoses, advance understanding of their causes, and identify opportunities for prevention. DESIGN: Retrospective review of 307 closed malpractice claims in which patients alleged a missed or delayed diagnosis in the ambulatory setting. SETTING: 4 malpractice insurance companies. MEASUREMENTS: Diagnostic errors associated with adverse outcomes for patients, process breakdowns, and contributing factors. RESULTS: A total of 181 claims (59%) involved diagnostic errors that harmed patients. Fifty-nine percent (106 of 181) of these errors were associated with serious harm, and 30% (55 of 181) resulted in death. For 59% (106 of 181) of the errors, cancer was the diagnosis involved, chiefly breast (44 claims [24%]) and colorectal (13 claims [7%]) cancer. The most common breakdowns in the diagnostic process were failure to order an appropriate diagnostic test (100 of 181 [55%]), failure to create a proper follow-up plan (81 of 181 [45%]), failure to obtain an adequate history or perform an adequate physical examination (76 of 181 [42%]), and incorrect interpretation of diagnostic tests (67 of 181 [37%]). The leading factors that contributed to the errors were failures in judgment (143 of 181 [79%]), vigilance or memory (106 of 181 [59%]), knowledge (86 of 181 [48%]), patient-related factors (84 of 181 [46%]), and handoffs (36 of 181 [20%]). The median number of process breakdowns and contributing factors per error was 3 for both (interquartile range, 2 to 4). LIMITATIONS: Reviewers were not blinded to the litigation outcomes, and the reliability of the error determination was moderate. CONCLUSIONS: Diagnostic errors that harm patients are typically the result of multiple breakdowns and individual and system factors. Awareness of the most common types of breakdowns and factors could help efforts to identify and prioritize strategies to prevent diagnostic errors.

Missed and delayed diagnoses in the emergency department: a study of closed malpractice claims from 4 liability insurers.

STUDY OBJECTIVES: Diagnostic errors in the emergency department (ED) are an important patient safety concern, but little is known about their cause. We identify types and causes of missed or delayed diagnoses in the ED. METHODS: This is a review of 122 closed malpractice claims from 4 liability insurers in which patients had alleged a missed or delayed diagnosis in the ED. Trained physician reviewers examined the litigation files and the associated medical records to determine whether an adverse outcome because of a missed diagnosis had occurred, what breakdowns were involved in the missed diagnosis, and what factors contributed to it. Main outcome measures were missed diagnoses, process breakdowns, and contributing factors. RESULTS: A total of 79 claims (65%) involved missed ED diagnoses that harmed patients. Forty-eight percent of these missed diagnoses were associated with serious harm, and 39% resulted in death. The leading breakdowns in the diagnostic process were failure to order an appropriate diagnostic test (58% of errors), failure to perform an adequate medical history or physical examination (42%), incorrect interpretation of a diagnostic test (37%), and failure to order an appropriate consultation (33%). The leading contributing factors to the missed diagnoses were cognitive factors (96%), patient-related factors (34%), lack of appropriate supervision (30%), inadequate handoffs (24%), and excessive workload (23%). The median numbers of process breakdowns and contributing factors per missed diagnosis were 2 and 3, respectively. CONCLUSION: Missed diagnoses in the ED have a complex cause. They are typically the result of multiple breakdowns in the diagnostic process and several contributing factors.

Claiming behaviour in a no-fault system of medical injury: a descriptive analysis of claimants and non-claimants.

OBJECTIVES: (i) To determine the proportion of patients in New Zealand who claim compensation from the national no-fault compensation program after experiencing a compensable injury; and (ii) to identify characteristics of injured patients who are least likely to claim despite having sustained a compensable injury. DESIGN: We estimated the percentage of eligible patients who claim no-fault compensation by linking a national claims database (Accident Compensation Corporation) to records reviewed in the New Zealand Quality of Healthcare Study (NZQHS). Bivariate and multivariate analyses were used to investigate socioeconomic and sociodemographic differences between claimants and injured non-claimants. PARTICIPANTS AND SETTING: Patients who experienced an adverse event associated with care in NZ public hospitals in 1998 and claimed compensation with the ACC, the national no-fault insurer (n = 741). Patients identified by the NZQHS as having sustained an adverse event associated with hospital care in the same year who did not file a compensation claim (n = 839). MAIN OUTCOME MEASURES: Adverse events, compensable adverse events, and compensation claims. RESULTS: Among patients judged by NZQHS reviewers to be eligible for compensation, 2.9% (6/210) claimed. Odds of claiming after an adverse event were significantly lower for patients who were elderly (odds ratio [OR], 0.20; 95% CI, 0.14-0.28), from the most deprived areas (OR, 0.36; 95% CI, 0.23-0.57), or of Ma ori or Pacific ethnicity (OR, 0.47; 95% CI, 0.32-0.69 and OR, 0.26, 95% CI, 0.11-0.58). CONCLUSIONS: Despite few apparent institutional or economic barriers, the proportion of injured patients in NZ who seek compensation after sustaining a compensable injury is very low. Hence, substantial underclaiming occurs in both negligence and no-fault systems. The disproportionately low propensity of elderly, poor and minority patients to seek compensation also appears to be pervasive.

Claims, errors, and compensation payments in medical malpractice litigation.

BACKGROUND: In the current debate over tort reform, critics of the medical malpractice system charge that frivolous litigation--claims that lack evidence of injury, substandard care, or both--is common and costly. METHODS: Trained physicians reviewed a random sample of 1452 closed malpractice claims from five liability insurers to determine whether a medical injury had occurred and, if so, whether it was due to medical error. We analyzed the prevalence, characteristics, litigation outcomes, and costs of claims that lacked evidence of error. RESULTS: For 3 percent of the claims, there were no verifiable medical injuries, and 37 percent did not involve errors. Most of the claims that were not associated with errors (370 of 515 [72 percent]) or injuries (31 of 37 [84 percent]) did not result in compensation; most that involved injuries due to error did (653 of 889 [73 percent]). Payment of claims not involving errors occurred less frequently than did the converse form of inaccuracy--nonpayment of claims associated with errors. When claims not involving errors were compensated, payments were significantly lower on average than were payments for claims involving errors (313,205 dollars vs. 521,560 dollars, P=0.004). Overall, claims not involving errors accounted for 13 to 16 percent of the system's total monetary costs. For every dollar spent on compensation, 54 cents went to administrative expenses (including those involving lawyers, experts, and courts). Claims involving errors accounted for 78 percent of total administrative costs. CONCLUSIONS: Claims that lack evidence of error are not uncommon, but most are denied compensation. The vast majority of expenditures go toward litigation over errors and payment of them. The overhead costs of malpractice litigation are exorbitant.

Health industry practices that create conflicts of interest: a policy proposal for academic medical centers.

Conflicts of interest between physicians' commitment to patient care and the desire of pharmaceutical companies and their representatives to sell their products pose challenges to the principles of medical professionalism. These conflicts occur when physicians have motives or are in situations for which reasonable observers could conclude that the moral requirements of the physician's roles are or will be compromised. Although physician groups, the manufacturers, and the federal government have instituted self-regulation of marketing, research in the psychology and social science of gift receipt and giving indicates that current controls will not satisfactorily protect the interests of patients. More stringent regulation is necessary, including the elimination or modification of common practices related to small gifts, pharmaceutical samples, continuing medical education, funds for physician travel, speakers bureaus, ghostwriting, and consulting and research contracts. We propose a policy under which academic medical centers would take the lead in eliminating the conflicts of interest that still characterize the relationship between physicians and the health care industry.

Analysis of surgical errors in closed malpractice claims at 4 liability insurers.

BACKGROUND: The relative importance of the different factors that cause surgical error is unknown. Malpractice claim file analysis may help to identify leading causes of surgical error and identify opportunities for prevention. METHODS: We retrospectively reviewed 444 closed malpractice claims, from 4 malpractice liability insurers, in which patients alleged a surgical error. Surgeon-reviewers examined the litigation file and medical record to determine whether an injury attributable to surgical error had occurred and, if so, what factors contributed. Detailed descriptive information concerning etiology and outcome was recorded. RESULTS: Reviewers identified surgical errors that resulted in patient injury in 258 of the 444 (58%) claims. Sixty-five percent of these cases involved significant or major injury; 23% involved death. In most cases (75%), errors occurred in intraoperative care; 25% in preoperative care; 35% in postoperative care. Thirty-one percent of the cases had errors occurring during multiple phases of care; in 62%, more than 1 clinician played a contributory role. Systems factors contributed to error in 82% of cases. The leading system factors were inexperience/lack of technical competence (41%) and communication breakdown (24%). Cases with technical errors (54%) were more likely than those without technical errors to involve errors in multiple phases of care (36% vs 24%, P = .03), multiple personnel (83% vs 63%, P < .001), lack of technical competence/knowledge (51% vs 29%, P < .001) and patient-related factors (54% vs 33%, P = .001). CONCLUSIONS: Systems factors play a critical role in most surgical errors, including technical errors. Closed claims analysis can help to identify priority areas for intervening to reduce errors.

"Health courts" and accountability for patient safety.

Proposals that medical malpractice claims be removed from the tort system and processed in an alternative system, known as administrative compensation or "health courts," attract considerable policy interest during malpractice "crises," including the current one. This article describes current proposals for the design of a health court system and the system's advantages for improving patient safety. Among these advantages are the cultivation of a culture of transparency regarding medical errors and the creation of mechanisms to gather and analyze data on medical injuries. The article discusses the experiences of foreign countries with administrative compensation systems for medical injury, including their use of claims data for research on patient safety; choices regarding the compensation system's relationship to physician disciplinary processes; and the proposed system's possible limitations.

Defensive medicine among high-risk specialist physicians in a volatile malpractice environment.

CONTEXT: How often physicians alter their clinical behavior because of the threat of malpractice liability, termed defensive medicine, and the consequences of those changes, are central questions in the ongoing medical malpractice reform debate. OBJECTIVE: To study the prevalence and characteristics of defensive medicine among physicians practicing in high-liability specialties during a period of substantial instability in the malpractice environment. DESIGN, SETTING, AND PARTICIPANTS: Mail survey of physicians in 6 specialties at high risk of litigation (emergency medicine, general surgery, orthopedic surgery, neurosurgery, obstetrics/gynecology, and radiology) in Pennsylvania in May 2003. MAIN OUTCOME MEASURES: Number of physicians in each specialty reporting defensive medicine or changes in scope of practice and characteristics of defensive medicine (assurance and avoidance behavior). RESULTS: A total of 824 physicians (65%) completed the survey. Nearly all (93%) reported practicing defensive medicine. "Assurance behavior" such as ordering tests, performing diagnostic procedures, and referring patients for consultation, was very common (92%). Among practitioners of defensive medicine who detailed their most recent defensive act, 43% reported using imaging technology in clinically unnecessary circumstances. Avoidance of procedures and patients that were perceived to elevate the probability of litigation was also widespread. Forty-two percent of respondents reported that they had taken steps to restrict their practice in the previous 3 years, including eliminating procedures prone to complications, such as trauma surgery, and avoiding patients who had complex medical problems or were perceived as litigious. Defensive practice correlated strongly with respondents' lack of confidence in their liability insurance and perceived burden of insurance premiums. CONCLUSION: Defensive medicine is highly prevalent among physicians in Pennsylvania who pay the most for liability insurance, with potentially serious implications for cost, access, and both technical and interpersonal quality of care.

Iatrogenic events resulting in intensive care admission: frequency, cause, and disclosure to patients and institutions.

PURPOSE: To identify the frequency and type of iatrogenic medical events requiring admission to an intensive care unit. To assess the consequences of iatrogenic medical events for patients and institutions. To assess the prevalence of disclosure of iatrogenic medical events to patients, surrogates, and institutions. METHODS: The project on Care Improvement for the Critically Ill enrolled 5727 patients to 8 intensive care units at 4 Boston teaching hospitals. To determine the nature, consequences, and disclosure of iatrogenic medical events, we did a retrospective chart review on all patients whose admission to an intensive care unit was precipitated by an iatrogenic event. RESULTS: Sixty-six patients (1.2 %) were identified by an intensive care unit's clinical team as having an iatrogenic medical event as the primary reason for admission to the unit. The majority (29, or 45%) of iatrogenic medical events were secondary to technical error, but a high percentage (21, or 33%) was due to iatrogenic drug events. Twenty-two (34%) cases were assessed by the investigators to have been preventable. In 60 (94%) cases there was no documentation in the patient's chart of communication to the patient regarding the reason for admission to the intensive care unit. In 11 (17%) cases there was documentation of a discussion with the surrogate about the reason for admission to the unit. In only 3 (5%) cases was there documentation that the patient or surrogate was informed that an iatrogenic medical event was the reason for admission to the intensive care unit. Incident reports or malpractice claims were filed in only 4 (6 %) cases. CONCLUSION: The frequency of iatrogenic medical events resulting in admission to intensive care units is lower than previous studies have reported. Iatrogenic drug events continue to be an important source of error. A considerable percentage of iatrogenic events may be preventable. Health care professionals rarely document disclosure of iatrogenic events to patients and surrogates.

Advising patients about patient safety: current initiatives risk shifting responsibility.

BACKGROUND: Many health care providers now disseminate advisories telling patients what they can do to avoid errors and harms in their care. METHODS: The content of five leading safety advisories for patients was analyzed and a critique of their development, content, and impact was developed, drawing on published literature and 40 interviews with a diverse sample of 50 key informants. FINDINGS: Very little is known about the effects of the distribution of safety advisories to patients, but several grounds for concern were identified. There was a lack of attention to patients' perspectives during the development of advisory messages, and the advisories say little about what health care providers should do to ensure patient safety. Patients are given little practical support to carry out the recommended actions, and health professionals' responses may render their attempts to act to secure their own safety ineffective. Some messages suggest an inappropriate shifting of responsibility onto patients. Advice that involves checking on or challenging health professionals' actions appears to be particularly problematic for patients. Such behaviors conflict with the expectations many people have--and think health professionals have--of patients' roles. DISCUSSION: A serious commitment to optimizing patients' contributions to safe care requires a research-based understanding of patients' perspectives and more practical facilitation of patient involvement.

Integration of an academic medical center and a community hospital: the Brigham and Women's/Faulkner hospital experience.

Brigham and Women's Hospital (BWH), a major academic tertiary medical center, and Faulkner Hospital (Faulkner), a nearby community teaching hospital, both in the Boston, Massachusetts area, have established a close affiliation relationship under a common corporate parent that achieves a variety of synergistic benefits. Formed under the pressures of limited capacity at BWH and excess capacity at Faulkner, and the need for lower-cost clinical space in an era of provider risk-sharing, BWH and Faulkner entered into a comprehensive affiliation agreement. Over the past seven years, the relationship has enhanced overall volume, broadened training programs, lowered the cost of resources for secondary care, and improved financial performance for both institutions. The lessons of this relationship, both in terms of success factors and ongoing challenges for the hospitals, medical staffs, and a large multispecialty referring physician group, are reviewed. The key factors for success of the relationship have been integration of training programs and some clinical services, provision of complementary clinical capabilities, geographic proximity, clear role definition of each institution, commitment and flexibility of leadership and medical staff, active and responsive communication, and the support of a large referring physician group that embraced the affiliation concept. Principal challenges have been maintaining the community hospital's cost structure, addressing cultural differences, avoiding competition among professional staff, anticipating the pace of patient migration, choosing a name for the new affiliation, and adapting to a changing payer environment.

Effects of a malpractice crisis on specialist supply and patient access to care.

OBJECTIVE: To investigate specialist physicians' practice decisions in response to liability concerns and their perceptions of the impact of the malpractice environment on patient access to care. SUMMARY BACKGROUND DATA: A perennial concern during "malpractice crises" is that liability costs will drive physicians in high-risk specialties out of practice, creating specialist shortages and access-to-care problems. METHODS: Mail survey of 824 Pennsylvania physicians in general surgery, neurosurgery, orthopedic surgery, obstetrics/gynecology, emergency medicine, and radiology eliciting information on practice decisions made in response to rising liability costs. RESULTS: Strong majorities of specialists reported increases over the last 3 years in patients' driving distances (58%) and waiting times (83%) for specialist care or surgery, waiting times for emergency department care (82%), and the number of patients forced to switch physicians (89%). Professional liability costs and managed care were both considered important contributing factors. Small proportions of specialists reported that they would definitely retire (7%) or relocate their practice out of state (4%) within the next 2 years; another third (32% and 29%, respectively) said they would likely do so. Forty-two percent of specialists have reduced or eliminated high-risk aspects of their practice, and 50% are likely to do so over the next 2 years. CONCLUSIONS: Our data suggest that claims of a "physician exodus" from Pennsylvania due to rising liability costs are overstated, but the malpractice situation is having demonstrable effects on the supply of specialist physicians in affected areas and their scope of practice, which likely impinges upon patients' access to care.

Race and family history assessment for breast cancer.

OBJECTIVE: Studies have demonstrated disparities in breast cancer screening between racial and ethnic groups. Knowledge of a woman's family history of breast cancer is important for initiating early screening interventions. The purpose of this study was to determine whether differences exist in the collection of family history information based on patient race. DESIGN: Cross-sectional patient telephone interview and medical record review. SETTING: Eleven primary care practices in the Greater Boston area, all associated with Harvard Medical School teaching hospitals. PARTICIPANTS: One thousand seven hundred fifty-nine women without a prior history of breast cancer who had been seen at least once by their primary care provider during the prior year. MEASUREMENTS AND MAIN RESULTS: Data were collected on patients regarding self-reported race, family breast cancer history information, and breast cancer screening interventions. Twenty-six percent (462/1,759) of the sample had documentation within their medical record of a family history for breast cancer. On multivariate analysis, after adjusting for patient age, education, number of continuous years in the provider's practice, language, and presentation with a breast complaint, white women were more likely to be asked about a breast cancer family history when compared to nonwhite women (odds ratio, 1.68; 95% confidence interval, 1.21 to 2.35). CONCLUSIONS: The majority of women seen by primary care providers do not have documentation of a family breast cancer history assessment within their medical record. White women were more likely to have family breast cancer information documented than nonwhites.
