Compensated Patient Injuries in the Treatment of Abdominal Aortic and Iliac Artery Aneurysms in Finland: A Nationwide Patient Insurance Registry Study.

OBJECTIVES: Patient injury claims data and insurance records provide detailed information on patient injuries. This study aimed to identify the errors and adverse events that led to patient injuries in vascular surgery for the treatments of abdominal aortic aneurysms (AAA) and iliac artery aneurysms (IAA) in Finland. The study also assessed the severity and preventability of the injuries. MATERIALS AND METHODS: A retrospective analysis of Finnish Patient Insurance Centre's insurance charts of compensated patient injuries in the treatment of AAA and IAA. Records of all compensated patient injury claims involving AAA and IAA between 2004 and 2017 inclusive were reviewed. Contributing factors to injury were identified and classified. The injuries were assessed for their preventability by using the WHO Surgical Safety Checklist correctly. The degree of harm was graded by Clavien-Dindo classification. RESULTS: Twenty-six patient injury incidents were identified in the treatment of 23 patients. Typical injuries involved delays in diagnosis or treatment, errors in surgical technique or injuries to adjacent anatomic organs. Three (13.0%) patients died due to patient injury. Two deaths were caused by delays in diagnosis of ruptured abdominal aortic aneurysm (RAAA) and the third death was due to missed diagnosis of post-operative myocardial infarction. Retained foreign material caused injuries to two (8.7%) patients. One (4.3%) patient had a severe postoperative infection. Three (13.0%) patients experienced an injury to an adjacent organ. One patient had a bilateral and another a unilateral above-the-knee amputation due to patient injury. Three injuries were considered preventable. Most harms were grade IIIb Clavien-Dindo classification in which injured patients required a surgical intervention under general anesthesia. CONCLUSIONS: Compensated patient injuries involving the treatment of AAA and IAA are rare, but are often serious. Injuries were identified during all stages of care. Most injuries involved open surgical procedures.

Low-frequency avoidable errors during transcarotid artery revascularization.

OBJECTIVE: Transcarotid artery revascularization (TCAR) seems to be a safe and effective alternative to carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TF-CAS). The TCAR system represents a paradigm shift in the management of carotid artery stenosis with potential for a significant decrease in periprocedural morbidity. However, as with CEA or TF-CAS, TCAR is associated with infrequent complications related to user technical error, most of which are preventable. Our goal is to describe these low-frequency events, and to provide guidelines for avoiding them. METHODS: The U.S. Food and Drug Administration (FDA) requires that all medical device manufacturers create a system for receiving, reviewing, and evaluating complaints (Code 21 of Federal Regulations 820.198). Silk Road Medical, Inc (Sunnyvale, Calif), has established a process by which all feedback, including complaints that may not meet FDA criteria, is captured and stored in a database for detailed analysis. More than 13,300 cases have been performed; submitted complaints were reviewed for incidents of serious injury and periprocedural complications, above and beyond the device-related events that must be reported to the FDA. RESULTS: A total of 13,334 patients have undergone TCAR worldwide between early 2011 and December 2019 using the SilkRoad device. Reported complications included 173 dissections (1.4% overall rate) of the common carotid artery at the access point, of which 22.5% were managed without intervention or with medical therapy alone and 24.3% were converted to CEA (considered failing safely). Errors in the location of stent deployment occurred in 16 cases (0.13%), with the most common site being the external carotid artery (75%). One wrong side carotid artery stent was placed in a patient with a high midline pattern of the bovine arch. Cranial nerve injury was reported in 11 cases (0.08%), only one of which persisted beyond 3 months. There have been three reported pneumothoraces and one reported chylothorax. Many of these errors can be recognized and prevented with careful attention to detail. CONCLUSIONS: In high-risk patients requiring treatment for carotid artery stenosis, TCAR has been proven as an alternative to TF-CAS with an excellent safety profile. As with CEA or TF-CAS, this procedure has the potential for infrequent complications, often as a result of user technical error. Although significant, these events can be avoided through a review of the collective experience to date and recognition of potential pitfalls, as we have described.

The patient died: What about involvement in the investigation process?

Patient and family involvement is high on the international quality and safety agenda. In this paper, we consider possible ways of involving families in investigations of fatal adverse events and how their greater participation might improve the quality of investigations. The aim is to increase awareness among healthcare professionals, accident investigators, policymakers and researchers and examine how research and practice can develop in this emerging field. In contrast to relying mainly on documentation and staff recollections, family involvement can result in the investigation having access to richer information, a more holistic picture of the event and new perspectives on who was involved and can positively contribute to the family's emotional satisfaction and perception of justice being done. There is limited guidance and research on how to constitute effective involvement. There is a need for co-designing the investigation process, explicitly agreeing the family's level of involvement, supporting and preparing the family, providing easily accessible user-friendly language and using different methods of involvement (e.g. individual interviews, focus group interviews and questionnaires), depending on the family's needs.

Morbidity and mortality conferences in general surgery: a narrative systematic review.

Background: In medical and surgical departments around the world, morbidity and mortality conferences (MMC) serve dual roles: they are cornerstones of quality-improvement programs and provide timely opportunities for education within the urgent context of clinical care. Despite the widespread adoption of MMCs, adverse events and preventable errors remain high or incompletely characterized, and opportunities to learn from and adjust to these events are frequently lost. This review examines the published literature on strategies to improve surgical MMCs. Methods: We searched OVID Medline, PubMed, Embase and CENTRAL. We defined our combination of search terms using a PICO (population, intervention, comparison, outcome) model, focusing on the use of MMCs in general surgery. Results: The MMC literature focused on 5 themes: educational value, error analysis, case selection and representation, attendance and dissemination. Strategies used to increase educational value included limiting case presentation time to 15-20 minutes, mandatory brief literature reviews, increasing audience interaction, and standardizing presentations using a PowerPoint template or SBAR (situation, background, assessment, recommendation) format. Interventions to improve error analysis included focused discussion on causative factors and taxonomic error analysis. Case selection was improved by using an electronic clinical registry, such as the National Surgery Quality Improvement Program, to better capture incidence of morbidity and mortality. Attendance was improved with teleconferencing. Dissemination strategies included MMC newsletters, incorporating MMCs into plan-do-check-act cycles, and surgeon report cards. Conclusion: Greater standardization of best practices may increase the quality improvement and educational impact of MMCs and provide a baseline to measure the effect of new MMC format innovations on the clinical and educational performance of surgical systems.

Contexte: Dans les services de médecine et de chirurgie du monde entier, les conférences sur la morbidité et la mortalité (CMM) jouent 2 rôles : elles forment la pierre angulaire des programmes d'amélioration de la qualité de soins et fournissent l'occasion de faire de l'enseignement dans le contexte même des soins cliniques immédiats. Malgré la popularité grandissante des CMM, le nombre d'événements indésirables et d'erreurs évitables demeure élevé ou mal caractérisé et on perd beaucoup d'occasions d'apprendre de ces événements et d'apporter les changements qui s'imposent. La présente revue analyse la littérature publiée sur les stratégies d'amélioration des CMM en chirurgie. Méthodes: Nous avons interrogé OVID Medline, PubMed, Embase et CENTRAL. Nous avons défini nos combinaisons de mots clés à l'aide du modèle PICO (population, intervention, comparaison et résultat [outcome]), en mettant l'accent sur l'utilisation des CMM en chirurgie générale. Résultats: La littérature sur les CMM se concentrait sur 5 thèmes : valeur didactique, analyse des erreurs, sélection et représentation des cas, participation et dissémination. Les stratégies utilisées pour accroître la valeur didactique incluaient limiter la durée des présentations de cas à 15­20 minutes, présenter de brèves revues de la littérature, favoriser les interactions avec l'auditoire et standardiser les présentations au moyen de modèles PowerPoint ou SBAR (situation, background, assessment, recommendation). Les interventions visant à améliorer l'analyse des erreurs incluaient une discussion sur les facteurs causaux et l'analyse des erreurs taxonomiques. La sélection des cas a été améliorée au moyen d'un registre clinique électronique comme le National Surgery Quality Improvement Program, pour mieux suivre l'incidence de la morbidité et de la mortalité. Les systèmes de téléconférences ont amélioré la participation. Parmi les stratégies de dissémination, mentionnons les bulletins sur les CMM, leur intégration aux cycles planifier/faire/vérifier/agir et les relevés de notes des chirurgiens. Conclusion: Une meilleure standardisation des pratiques optimales pourrait améliorer davantage la qualité des soins et augmenter l'impact didactique des CMM en plus d'offrir une base de référence pour mesurer l'effet des nouvelles mesures appliquées aux CMM sur le rendement clinique et didactique des systèmes chirurgicaux.

Aggregate analysis of sentinel events as a strategic tool in safety management can contribute to the improvement of healthcare safety.

OBJECTIVE: To examine if clustering of root causes of sentinel events (SEs) can contribute to organisational improvement of healthcare and patient safety by providing insight into organisational risk factors, patterns and trends. DESIGN: Retrospective, cross-sectional review of SEs from a hospital database reported to the Board of directors in 2016. SETTING: A regional teaching hospital in the Netherlands. INTERVENTION(S): Clustering of characteristics and variables of SEs to establish vulnerabilities and patterns of failure factors of the organisation. MAIN OUTCOME MEASURE(S): Characteristics and contributory causes of failure of SEs identified via root cause analysis (RCA). Outcomes reported using descriptive statistics. RESULTS: A total of 21 events were included involving 21 patients. Mean age was 56.7 years (SD 24.4), 71.4% were above 50 years of age. In 81.8%, the care was multi-disciplinary and in 76.2% the event resulted in permanent harm or injury. Of the 132 identified contributory root causes, most were related to human factors (53.8%) and organisational factors (40.2%). Technical and patient-related factors were identified in 3.0%. Organisational improvement strategies focused on the care of elderly patients, patients subjected to multi-disciplinary care and on improving knowledge, protocols and coordination of care. CONCLUSION: Clustering variables of SEs and contributory factors of failure through RCA helps to delineate a hospital-specific profile by providing a detailed insight into risk factors, patterns and trends in an organisation and to determine the best strategies for improvement by drawing lessons across events.

Deaths in Incorrectly Identified Low-Surgical-Risk Patients.

BACKGROUND: The American Society of Anesthesiologists (ASA) physical classification system was developed for assessing anaesthetic risk, but is often also used to estimate surgical death risk. Patients with low ASA grades (ASA 1 or 2) are expected to have better surgical outcomes than patients with higher ASA grades (ASA ≥ 4). This study examined the course to death in patients classified as ASA 1 or 2 was examined, to investigate possible factors in unexpected deaths, in addition to evaluating the use of ASA grades by clinicians. METHODS: Patient data from the national surgical mortality audit of Australian hospitals were examined. The patient group was listed as ASA grade 1 or 2 by surgeons. Patients over 60 or under 20 were excluded in the final analysis, as were cases from New South Wales due to data not being available. A total of 357 cases were examined. Assessor summaries of the cases were examined, and ASA score reassessed to determine accuracy. RESULTS: More than 95% (n = 339) of cases listed as ASA 1 or 2 were found to have an incorrectly low grade, with 17.6% (n = 63) of cases listed as "expected" deaths. CONCLUSION: ASA grades appear to be misunderstood in the reporting of patient surgical risk. Many patient summaries list patients with severe systemic disease or expected deaths as ASA 1 or 2, contrary to the intended use of this classification system. Improved education on the use of the ASA grading system would be beneficial to clinicians.

An evaluation by the Norwegian Health Care Supervision Authorities of events involving death or injuries in maternity care.

INTRODUCTION: We aimed to determine how serious adverse events in obstetrics were assessed by supervision authorities. MATERIAL AND METHODS: We selected cases investigated by supervision authorities during 2009-2013. We analyzed information about who reported the event, the outcomes of the mother and infant, and whether events resulted from errors at the individual or system level. We also assessed whether the injuries could have been avoided. RESULTS: During the study period, there were 303 034 births in Norway, and supervision authorities investigated 338 adverse events in obstetric care. Of these, we studied 207 cases that involved a serious outcome for mother or infant. Five mothers (2.4%) and 88 infants (42.5%) died. Of the 207 events reported to the supervision authorities, patients or relatives reported 65.2%, hospitals reported 39.1%, and others reported 4.3%. In 8.7% of cases, events were reported by more than 1 source. The supervision authority assessments showed that 48.3% of the reported cases involved serious errors in the provision of health care, and a system error was the most common cause. We found that supervision authorities investigated significantly more events in small and medium-sized maternity units than in large units. Eighteen health personnel received reactions; 15 were given a warning, and 3 had their authority limited. We determined that 45.9% of the events were avoidable. CONCLUSIONS: The supervision authorities investigated 1 in 1000 births, mainly in response to complaints issued from patients or relatives. System errors were the most common cause of deficiencies in maternity care.

"Doctors Killed My Baby": Argumentative Patterns in Medical Disputes in China.

The recent surge in medical disputes requires that more attention be paid to the voices of laypeople. This article explores the argumentative nature of the public discourse of the reported "malpractice mobs" that strive to convince members of the public (in the place of health or legal experts) that they have been victims of medical errors and injustice. This case-based qualitative empirical study uses a pragma-dialectical approach to suggest a prototypical pattern of such public appeals that contains a basic argumentative pattern and various types of extensions. The presence and influence of cultural factors are identified and discussed. The results of the analysis indicate that "malpractice mobs" largely display a tendency to target certain drugs, treatments or therapeutic methods based on folk interpretations of medical phenomena among individual ethnic groups, which may be regarded as cultural preferences in the medical domain. Although these preferences have little coercive power, in the absence of institutional restraints, they may have a powerful impact. The introduction of cultural preferences into pragmatic argumentation explains not only why some critical questions are emphasized (whereas others are invariably ignored) but also why certain types of support are repeatedly demanded in public appeals. The findings suggest the importance of paying greater attention to the argumentation of laypeople in medical disputes in China and the essential role of a culturally sensitive model of argumentation theory in improving health communication.

The development of search filters for adverse effects of surgical interventions in medline and Embase.

BACKGROUND: Search filter development for adverse effects has tended to focus on retrieving studies of drug interventions. However, a different approach is required for surgical interventions. OBJECTIVE: To develop and validate search filters for medline and Embase for the adverse effects of surgical interventions. METHODS: Systematic reviews of surgical interventions where the primary focus was to evaluate adverse effect(s) were sought. The included studies within these reviews were divided randomly into a development set, evaluation set and validation set. Using word frequency analysis we constructed a sensitivity maximising search strategy and this was tested in the evaluation and validation set. RESULTS: Three hundred and fifty eight papers were included from 19 surgical intervention reviews. Three hundred and fifty two papers were available on medline and 348 were available on Embase. Generic adverse effects search strategies in medline and Embase could achieve approximately 90% relative recall. Recall could be further improved with the addition of specific adverse effects terms to the search strategies. CONCLUSION: We have derived and validated a novel search filter that has reasonable performance for identifying adverse effects of surgical interventions in medline and Embase. However, we appreciate the limitations of our methods, and recommend further research on larger sample sizes and prospective systematic reviews.

[Safety of patients and adverse events related thereto in medicine]. / Bezopasnost' patsientov i sviazannye s nei neblagopriiatnye sobytiia v meditsine.

The article deals with the analysis of retrospective and prospective studies dedicated to examining patient safety regarding epidemiology, frequency and severity of adverse events associated with rendering medical care. Electronic retrieval was carried out over the period from 1990 to 2017 using the following databases: MEDLINE, Cochrane Collaboration, EMBASE, SCOPUS, ISI Web of Science. The carried out meta-analysis made it possible to determine that cases of doing harm (adverse events) while rendering medical care are registered in 10.6% of patients. More than 80% of adverse events occur in hospital, with more than half of them revealed in the operating room and about third in a patient ward. While rendering medical care outside hospital, more often cases of doing harm are observed due to medical errors made in the physician's office and due to the patient's behaviour at home. The majority of adverse events appeared to be associated with performing an operation, manipulation, carrying out drug therapy, late or inappropriate treatment and diagnosis. Unexpected death secondary to unfavourable events is observed in 5.3% of patients. In the structure of in-hospital mortality, the proportion of deaths associated with rendering medical care accounts for 24.9% and in the structure of overall population mortality - for 9.7%, ranking third amongst all causes.

A Contemporary Medicolegal Analysis of Outpatient Medication Management in Chronic Pain.

BACKGROUND: Opioids are frequently used in chronic pain management but are associated with significant morbidity and mortality in some patient populations. An important avenue for identifying complications-including serious or rare complications-is the study of closed malpractice claims. The present study is intended to complement the existing closed claims literature by drawing on claims from a more recent timeframe through a partnership with a large malpractice carrier, the Controlled Risk Insurance Company (CRICO). The goal of this study was to identify patient medical comorbidities and aberrant drug behaviors, as well as prescriber practices associated with patient injury and malpractice claims. Another objective was to identify claims most likely to result in payments and use this information to propose a strategy for reducing medicolegal risk. METHODS: The CRICO Strategies Comparative Benchmarking System is a database of claims drawing from >350,000 malpractice claims from Harvard-affiliated institutions and >400 other academic and community institutions across the United States. This database was queried for closed claims from January 1, 2009, to December 31, 2013, and identified 37 cases concerning noninterventional, outpatient chronic pain management. Each file consisted of a narrative summary, including expert witness testimony, as well as coded fields for patient demographics, medical comorbidities, the alleged damaging event, the alleged injurious outcome, the total financial amount incurred, and more. We performed an analysis using these claim files. RESULTS: The mean patient age was 43.5 years, with men representing 59.5% of cases. Payments were made in 27% of cases, with a median payment of $72,500 and a range of $7500-$687,500. The majority of cases related to degenerative joint disease of the spine and failed back surgery syndrome; no patients in this series received treatment of malignant pain. Approximately half (49%) of cases involved a patient death. The use of long-acting opioids and medical conditions affecting the cardiac and pulmonary systems were more closely associated with death than with other outcomes. The nonpain medical conditions present in this analysis included obesity, obstructive sleep apnea, chronic obstructive pulmonary disease, hypertension, and coronary artery disease. Other claims ranged from alleged addiction to opioids from improper prescribing to alleged abandonment with withdrawal of care. The CRICO analysis suggested that patient behavior contributed to over half of these claims, whereas deficits in clinical judgment contributed to approximately 40% of the claims filed. CONCLUSIONS: Claims related to outpatient medication management in pain medicine are multifactorial, stemming from deficits in clinical judgment by physicians, noncooperation in care by patients, and poor clinical documentation. Minimization of both legal risk and patient harm can be achieved by carefully selecting patients for chronic opioid therapy and documenting compliance and improvement with the treatment plan. Medical comorbidities such as obstructive sleep apnea and the use of long-acting opioids may be particularly dangerous. Continuing physician education on the safest and most effective approaches to manage these medications in everyday practice will lead to both improved legal security and patient safety.

Maternal mortality audit in Suriname between 2010 and 2014, a reproductive age mortality survey.

BACKGROUND: The fifth Millennium Development Goal (MDG-5) aimed to improve maternal health, targeting a maternal mortality ratio (MMR) reduction of 75% between 1990 and 2015. The objective of this study was to identify all maternal deaths in Suriname, determine the extent of underreporting, estimate the reduction, audit the maternal deaths and assess underlying causes and substandard care factors. METHODS: A reproductive age mortality survey was conducted in Suriname (South-American upper-middle income country) between 2010 and 2014 to identify all maternal deaths in the country. MMR was compared to vital statistics and a previous confidential enquiry from 1991 to 1993 with a MMR 226. A maternal mortality committee audited the maternal deaths and identified underlying causes and substandard care factors. RESULTS: In the study period 65 maternal deaths were identified in 50,051 live births, indicating a MMR of 130 per 100.000 live births and implicating a 42% reduction of maternal deaths in the past 25 years. Vital registration indicated a MMR of 96, which marks underreporting of 26%. Maternal deaths mostly occurred in the urban hospitals (84%) and the causes were classified as direct (63%), indirect (32%) or unspecified (5%). Major underlying causes were obstetric and non-obstetric sepsis (27%) and haemorrhage (20%). Substandard care factors (95%) were mostly health professional related (80%) due to delay in diagnosis (59%), delay or wrong treatment (78%) or inadequate monitoring (59%). Substandard care factors most likely led to death in 47% of the cases. CONCLUSION: Despite the reduction in maternal mortality, Suriname did not reach MDG-5 in 2015. Steps to reach the Sustainable Development Goal in 2030 (MMR ≤ 70 per 100.000 live births) and eliminate preventable deaths include improving data surveillance, installing a maternal death review committee, and implementing national guidelines for prevention and management of major complications of pregnancy, childbirth and puerperium.

Medical morbidity and mortality conferences: past, present and future.

Morbidity and mortality conferences (MMCs) have three potential aims-to improve patient safety by reducing adverse events and preventable deaths, to improve overall quality of care as part of the hospital governance structure and as educational learning events. At present, medical MMCs vary widely in format and attendance from hospital to hospital. The evidence for MMCs actually reducing adverse events and preventing avoidable deaths is disappointing. There is better evidence for their educational role. The majority of medical deaths in hospitals are frail older people with poor life expectancy in whom inadequate care is more likely to be due to errors of omission rather than commission. Medical MMCs should be multidisciplinary and led by a senior clinician to encourage discussion and reflection in a 'blame-free' environment. They should be learning events for both clinicians and the organisation as a whole with a structure to support this.

Prevalence and preventability of sentinel events in Saudi Arabia: analysis of reports from 2012 to 2015.

This study aimed to assess the pattern of sentinel events reported to Ministry of Health of Saudi Arabia from January 2012 to June 2015. Sentinel event reports were examined for patient characteristics, type of event, outcome, cause and preventability. There were 433 sentinel events: 58.2% were deaths, 14.8% were unexpected loss of a limb or a function, 7.4% major medication errors and 7.4% retained instruments or sponges. Among the reported events, 44% were associated with surgical interventions and most were classified as preventable (91.6%). Age 19-64 years was significantly associated with death as an outcome (P = 0.02). Non-preventable sentinel events were significantly more likely among women than men (P = 0.01). Unavailability of policy and procedures and/ or failure to implement them (55%), and lack of proper communication (35%) and training (33%) were the main causes for the adverse events. Efforts should focus on enhancing the National Sentinel Events Reporting System, adopting criteria for effective reporting and ensuring availability and implementation of policies and procedures.

Occurrence of "never events" after major open vascular surgery procedures.

OBJECTIVE: "Never events" refers to harmful hospital-acquired conditions that the Centers for Medicare and Medicaid Services identified in 2008 as largely preventable and that would no longer be reimbursed. Our goal was to identify the incidence, predictive factors, temporal trend, and associated consequences of never events after major open vascular surgery procedures. METHODS: The Nationwide Inpatient Sample (NIS) (2003-2011) was queried to identify never events applicable to vascular surgery patients, including air embolism, catheter-based urinary tract infections (UTIs), stage 3 and 4 pressure ulcers, falls/trauma, blood incompatibility, vascular catheter infections, complications of poor glucose control, retained foreign objects, and wrong-site surgery. We specifically evaluated open abdominal aortic aneurysm repair, carotid endarterectomy, and lower extremity bypass/femoral endarterectomy. Multivariable logistic regression was used to predict never events based on preoperative variables. Multivariable logistic and gamma regression models were used to study mortality, hospital length of stay (LOS), and charges. RESULTS: Never events were identified in 774 of 267,734 patients. The distribution of never events were falls/trauma (59%), pressure ulcers (19%), catheter-based UTI (9%), vascular catheter infection (6%), complications of poor glucose control (5%), and retained objects (4%). Rates of falls and catheter-based UTIs have increased since 2008. Multivariable predictors of any never event included lower extremity bypass, abdominal aortic aneurysm, weight loss, nonelective admission, paralysis, repair, congestive heart failure, altered mental status, renal failure, weekend admission, diabetes, female gender, and age. Race, insurance, hospital type, income level, geography, July to September admission, and other comorbidities were not predictive. After risk factor adjustment, never events were associated with increased perioperative mortality (odds ratio, 2.7; 95% confidence interval [CI], 1.5-34.8; P < .001), LOS (means ratio, 1.9; 95% CI, 1.7-2.0; P < .001), and total charges (means ratio, 1.7; 95% CI, 1.6-1.8; P < .001). CONCLUSIONS: Never events after major vascular surgery are associated with a number of perioperative factors and are predictive of increased charges, LOS, and mortality. Falls and catheter-based UTIs have increased in frequency since the Centers for Medicare and Medicaid Services announced that it would no longer reimburse for these complications. This study establishes baseline never event rates in the vascular surgery patient population and identifies high-risk patients to target for quality improvement.

A review of patient safety incidents reported as 'severe' or 'death' from critical care units in England and Wales between 2004 and 2014.

We analysed 1743 patient safety incidents reported between 2004 and 2014 from critical care units in England and Wales where the harm had been classified as 'severe' (1346, 77%) or 'death' (397, 23%). We classified 593 (34%) of these incidents as resulting in temporary harm, and 782 (45%) as more than temporary harm, of which 389 (22%) may have contributed to the patient's death. We found no described harm in 368 (21%) incidents. We classified 1555 (89%) of the incidents as being avoidable or potentially avoidable. There were changes over time for some incident types (pressure sores: 10 incidents in 2007, 64 in 2012; infections: 60 incidents in 2007, 10 in 2012) and some changes in response to national guidance. We made a comparison with a dataset of all incidents reported from units in North-West England, and this confirmed that the search strategy identified more severe incidents, but did not identify all incidents that contributed to mortality.

Learning from mistakes in the NHS: a special PHSO report.

John Tingle discusses a special report by the Parliamentary and Health Service Ombudsman (PHSO) into how the NHS failed to investigate properly the death of a 3-year-old child.

[The factors affecting the results of mechanical jaundice management]. / Faktory, vliyayushchie na rezul'taty lecheniya bol'nykh s mekhanicheskoi zheltukhoi.

AIM: To improve the results of obstructive jaundice management by rational diagnostic and treatment strategies. MATERIAL AND METHODS: Outcomes of 820 patients with obstructive jaundice syndrome were analyzed. RESULTS: Diagnostic and tactical mistakes were made at pre-hospital stage in 143 (17.4%) patients and in 105 (12.8%) at hospital stage. Herewith, in 53 (6.5%) cases the errors were observed at all stages. Retrospective analysis of severe postoperative complications and lethal outcomes in patients with obstructive jaundice showed that in 23.8% of cases they were explained by diagnostic and tactical mistakes at various stages of examination and treatment. CONCLUSION: We developed an algorithm for obstructive jaundice management to reduce the number of diagnostic and tactical errors, a reduction in the frequency of diagnostic and tactical errors. It reduced the number of postoperative complications up to 16.5% and mortality rate to 3.0%.
