The epidemiology of malpractice claims in primary care: a systematic review

Triage Versus Obstetric Emergency Department and Main Emergency Department: Best Practices

An obstetric emergency department (OBED) allows for timely, standardized and quality care by a clinician for pregnant patients presenting unscheduled to a hospital. Understanding the differences between a traditional labor and delivery triage model and an OBED are important in developing a successful, safe, and quality obstetric program that meets the needs of the community with appropriate resource allocation. The benefits in an OBED of every patient seen in a timely fashion by a clinician, and ultimately the impact on outcomes are noteworthy and should be considered when developing a labor and delivery unit.

Role of knowledge and reasoning processes as predictors of resident physicians' susceptibility to anchoring bias in diagnostic reasoning: a randomised controlled experiment

BACKGROUND

Diagnostic errors have been attributed to reasoning flaws caused by cognitive biases. While experiments have shown bias to cause errors, physicians of similar expertise differed in susceptibility to bias. Resisting bias is often said to depend on engaging analytical reasoning, disregarding the influence of knowledge. We examined the role of knowledge and reasoning mode, indicated by diagnosis time and confidence, as predictors of susceptibility to anchoring bias. Anchoring bias occurs when physicians stick to an incorrect diagnosis triggered by early salient distracting features (SDF) despite subsequent conflicting information.

METHODS

Sixty-eight internal medicine residents from two Dutch university hospitals participated in a two-phase experiment. Phase 1: assessment of knowledge of discriminating features (ie, clinical findings that discriminate between lookalike diseases) for six diseases. Phase 2 (1 week later): diagnosis of six cases of these diseases. Each case had two versions differing exclusively in the presence/absence of SDF. Each participant diagnosed three cases with SDF (SDF+) and three without (SDF-). Participants were randomly allocated to case versions. Based on phase 1 assessment, participants were split into higher knowledge or lower knowledge groups.

MAIN OUTCOME MEASUREMENTS

frequency of diagnoses associated with SDF; time to diagnose; and confidence in diagnosis.

RESULTS

While both knowledge groups performed similarly on SDF- cases, higher knowledge physicians succumbed to anchoring bias less frequently than their lower knowledge counterparts on SDF+ cases (p=0.02). Overall, physicians spent more time (p<0.001) and had lower confidence (p=0.02) on SDF+ than SDF- cases (p<0.001). However, when diagnosing SDF+ cases, the groups did not differ in time (p=0.88) nor in confidence (p=0.96).

CONCLUSIONS

Physicians apparently adopted a more analytical reasoning approach when presented with distracting features, indicated by increased time and lower confidence, trying to combat bias. Yet, extended deliberation alone did not explain the observed performance differences between knowledge groups. Success in mitigating anchoring bias was primarily predicted by knowledge of discriminating features of diagnoses.

Prevalence and clinical significance of incidental findings in chest and abdominopelvic CT scans of trauma patients; A cross-sectional study

BACKGROUND

Imaging may inadvertently reveal pathologies unrelated to their performing purpose, known as incidental findings (IF). This study aimed to assess the prevalence, clinical significance, and documentation of IFs in chest and abdominopelvic computed tomography (CT) scans of trauma patients.

METHODS

This observational study was conducted at two urban level-1 trauma centers from March 2019 through April 2022. Official radiology reports of trauma patients who underwent chest and/or abdominopelvic CT scans at the emergency department (ED) were explored, and IF were extracted. Predictive factors of the presence of IFs and their documenting were investigated.

RESULTS

Out of 656 chest and 658 abdominopelvic CT scans, 167 (25.37%) and 212 (32.31%) scans harbored at least one IF, respectively. Patients with IFs tended to be of higher age and female in both chest (age: 48 [IQR: 35-62] vs. 34 [IQR: 25-42.5]; female: 31.14% vs 14.66%, p < 0.001 for both) and abdominopelvic CT scans (age: 41 [IQR: 30-57.5] vs 33 [IQR: 25-43], female: 26.42% vs. 13.96%, p < 0.001 for both). As for documentation of significant IFs, only 49 of 112 chest IFs (43.8%) and 55 of 176 abdominopelvic IFs (31.3%) were documented. Investigating factors associated with documentation of clinically significant IFs, shorter length of hospital stay (1.5 (IQR: 0-4) vs. 3 (IQR: 2-8), p = 0.003), and discharging by ED physicians (documentation rate: 13.2% vs 42.6%, p < 0.001) were associated with poorer documentation of IFs only in abdominopelvic scans.

CONCLUSION

CT imaging in ED trauma patients often reveals incidental findings, especially in older patients. Over 50% of these findings are clinically significant, yet they are frequently ignored and not documented. Physicians need to be more vigilant in recognizing and documenting these incidental findings and informing patients of the need for further evaluation.

Effects of interacting with a large language model compared with a human coach on the clinical diagnostic process and outcomes among fourth-year medical students: study protocol for a prospective, randomised experiment using patient vignettes

INTRODUCTION

Versatile large language models (LLMs) have the potential to augment diagnostic decision-making by assisting diagnosticians, thanks to their ability to engage in open-ended, natural conversations and their comprehensive knowledge access. Yet the novelty of LLMs in diagnostic decision-making introduces uncertainties regarding their impact. Clinicians unfamiliar with the use of LLMs in their professional context may rely on general attitudes towards LLMs more broadly, potentially hindering thoughtful use and critical evaluation of their input, leading to either over-reliance and lack of critical thinking or an unwillingness to use LLMs as diagnostic aids. To address these concerns, this study examines the influence on the diagnostic process and outcomes of interacting with an LLM compared with a human coach, and of prior training vs no training for interacting with either of these 'coaches'. Our findings aim to illuminate the potential benefits and risks of employing artificial intelligence (AI) in diagnostic decision-making.

METHODS AND ANALYSIS

We are conducting a prospective, randomised experiment with N=158 fourth-year medical students from Charité Medical School, Berlin, Germany. Participants are asked to diagnose patient vignettes after being assigned to either a human coach or ChatGPT and after either training or no training (both between-subject factors). We are specifically collecting data on the effects of using either of these 'coaches' and of additional training on information search, number of hypotheses entertained, diagnostic accuracy and confidence. Statistical methods will include linear mixed effects models. Exploratory analyses of the interaction patterns and attitudes towards AI will also generate more generalisable knowledge about the role of AI in medicine.

ETHICS AND DISSEMINATION

The Bern Cantonal Ethics Committee considered the study exempt from full ethical review (BASEC No: Req-2023-01396). All methods will be conducted in accordance with relevant guidelines and regulations. Participation is voluntary and informed consent will be obtained. Results will be published in peer-reviewed scientific medical journals. Authorship will be determined according to the International Committee of Medical Journal Editors guidelines.

Lessons learnt on patient safety in dentistry through a 5-year nationwide database study on iatrogenic harm

Safe delivery of care is a priority in dentistry, while basic epidemiological knowledge of patient safety incidents is still lacking. The objectives of this study were to (1) classify patient safety incidents related to primary dental care in Denmark in the period 2016-2020 and study the distribution of different types of dental treatment categories where harm occurred, (2) clarify treatment categories leading to "nerve injury" and "tooth loss" and (3) assess the financial cost of patient-harm claims. Data from the Danish Dental Compensation Act (DDCA) database was retrieved from all filed cases from 1st January 2016 until 31st December 2020 pertaining to: (1) The reason why the patient applied for treatment-related harm compensation, (2) the event that led to the alleged harm (treatment category), (3) the type of patient-harm, and (4) the financial cost of all harm compensations. A total of 9069 claims were retrieved, of which 5079 (56%) were found eligible for compensation. The three most frequent categories leading to compensation were "Root canal treatment and post preparation"(n = 2461, 48% of all approved claims), "lack of timely diagnosis and initiation of treatment" (n = 905, 18%) and "surgery" (n = 878, 17%). Damage to the root of the tooth accounted for more than half of all approved claims (54.36%), which was most frequently a result of either parietal perforation during endodontic treatment (18.54%) or instrument fracture (18.89%). Nerve injury accounted for 16.81% of the approved claims. Total cost of all compensation payments was €16,309,310, 41.1% of which was related to surgery (€6,707,430) and 20.4% (€3,322,927) to endodontic treatment. This comprehensive analysis documents that harm permeates all aspects of dentistry, especially in endodontics and surgery. Neglect or diagnostic delays contribute to 18% of claims, indicating that harm does not solely result from direct treatment. Treatment harm inflicts considerable societal costs.

Medical malpractice in Oman: A 12-year retrospective record review

BACKGROUND

There is a paucity of studies documenting medical malpractice litigation in countries of the Arabian Gulf, such as Oman.

OBJECTIVES

To describe the characteristics of malpractice claims, the outcomes decided by the medical liability committee, and predictors of medical errors.

METHODS

This is a retrospective observational study that reviewed medical malpractice cases registered in Oman over a 12-year period (2010-2021) with the medical liability committee, known as the Higher Medical Committee (HMC). Descriptive and inferential statistical techniques, including multiple logistic regression techniques, were used for data analysis.

RESULTS

Between 2010 and 2021, the HMC registered 1284 medical malpractice cases, out of which 1048 were fully investigated. The number of registered cases increased during this period. These cases included those raised by Omani nationals and expatriates, with a majority (86%) raised by Omani complainants. Two-thirds (67%) of the cases involved adult complainants aged 18-60 years. About 43% of the cases were from the urban Muscat region, and 68% were related to public hospitals. The most common specialties involved were obstetrics and gynecology (20.1%), internal medicine (19.7%), surgery (17.6%) and orthopedics (13.8%). Half (51%) of the appeals or grievances were dismissed because they were not preceded by medical negligence or malpractice. The average waiting time to initiate the investigation was 10 months. Errors were more common among non-Omani complainants and cases related to private hospitals. Significant predictors of errors included nationality (i.e. Omani vs. non-Omani), the referring institution, the medical specialty and the type of health institution involved, and the waiting time to initiate the investigation.

CONCLUSION

To date, the number of cases of medical malpractice in Oman is lower compared to international trends, although there has been an upsurge in recent years. More research using a more robust methodology is warranted to contextualise the factors that contribute to this upward trend, as well as the preponderance in urban settings and among certain demographic populations.

Critical Review of Oncologic Medical Malpractice Claims Against Orthopaedic Surgeons

INTRODUCTION

The purpose of this study was to determine the most common allegations for malpractice litigation brought against orthopaedic surgeons for oncologic matters and the resulting verdicts.

METHODS

The Westlaw Legal research database was queried for malpractice cases filed against orthopaedic surgeons for oncologic matters in the United States after 1980. Plaintiff demographics, state of filing, allegations, and outcomes of lawsuits were recorded and reported accordingly.

RESULTS

A total of 36 cases met the inclusion and exclusion criteria and were subsequently included in the final analysis. The overall rate of cases filed remained consistent through the past four decades and was primarily related to a primary sarcoma diagnosis in adult women. The primary reason for litigation was failure to diagnose a primary malignant sarcoma (42%) followed by failure to diagnose unrelated carcinoma (19%). The most common states of filing were primarily located in the Northeast (47%), where a plaintiff verdict was also more commonly encountered as compared with other regions. Damages awarded averaged $1,672,500 with a range of $134, 231 to $6,250,000 and a median of $918,750.

CONCLUSION

Failure to diagnose primary malignant sarcoma and unrelated carcinoma was the most common reason for oncologic litigation brought against orthopaedic surgeons. Although most of the cases ruled in favor of the defendant surgeon, it is important for orthopaedic surgeons to be aware of the potential errors that not only prevent litigation but also improve patient care.

Diagnostic consistency between admission and discharge of pediatric cases in a tertiary teaching hospital in China

BACKGROUND

Patient-centered, high-quality health care relies on accurate and timely diagnosis. Diagnosis is a complex, error-prone process. Prevention of errors involves understanding the cause of errors. This study investigated diagnostic discordance between admission and discharge in pediatric cases.

METHODS

We retrospectively reviewed the electronic medical records of 5381 pediatric inpatients during 2017-2018 in a tertiary teaching hospital. We analyzed diagnostic consistency by comparing the first 4 digits of admission and discharge ICD-10 codes of the cases and classified them as concordant for "complete and partial match" or discordant for "no match".

RESULTS

Diagnostic discordance was observed in 49.2% with the highest prevalence in infections of the nervous and respiratory systems (Ps < 0.001). Multiple (multivariable) logistic regression analysis predicted a lower risk of diagnostic discordance with older children (aOR, 95%CI: 0.94, 0.93-0.96) and a higher risk with infectious diseases (aOR, 95%CI: 1.49, 1.33-1.66) and admission by resident and attending pediatricians (aOR, 95%CI: 1.41, 1.30-1.54). Discordant cases had a higher rate of antibiotic prescription (OR, 95%CI: 2.09, 1.87-2.33), a longer duration of antibiotic use (P = 0.02), a longer length of hospital stay (P < 0.001), and higher medical expenses (P < 0.001).

CONCLUSIONS

This study denotes a considerably high rate of discordance between admission and discharge diagnoses with an associated higher and longer prescription of antibiotics, a longer length of stay, and higher medical expenses among Chinese pediatric inpatient cases. Infectious diseases were identified as high-risk clinical conditions for discordance. Considering potential diagnostic and coding errors, departmental investigation of preventable diagnostic discordance is suggested for quality health care and preventing potential medicolegal consequences.

Identifying and prioritizing educational content from a malpractice claims database for clinical reasoning education in the vocational training of general practitioners

Diagnostic reasoning is an important topic in General Practitioners' (GPs) vocational training. Interestingly, research has paid little attention to the content of the cases used in clinical reasoning education. Malpractice claims of diagnostic errors represent cases that impact patients and that reflect potential knowledge gaps and contextual factors. With this study, we aimed to identify and prioritize educational content from a malpractice claims database in order to improve clinical reasoning education in GP training. With input from various experts in clinical reasoning and diagnostic error, we defined five priority criteria that reflect educational relevance. Fifty unique medical conditions from a malpractice claims database were scored on those priority criteria by stakeholders in clinical reasoning education in 2021. Subsequently, we calculated the mean total priority score for each condition. Mean total priority score (min 5-max 25) for all fifty diagnoses was 17,11 with a range from 13,89 to 19,61. We identified and described the fifteen highest scoring diseases (with priority scores ranging from 18,17 to 19,61). The prioritized conditions involved complex common (e.g., cardiovascular diseases, renal insufficiency and cancer), complex rare (e.g., endocarditis, ectopic pregnancy, testicular torsion) and more straightforward common conditions (e.g., tendon rupture/injury, eye infection). The claim cases often demonstrated atypical presentations or complex contextual factors. Including those malpractice cases in GP vocational training could enrich the illness scripts of diseases that are at high risk of errors, which may reduce diagnostic error and related patient harm.

Concordance with urgent referral guidelines in patients presenting with any of six 'alarm' features of possible cancer: a retrospective cohort study using linked primary care records

BACKGROUND

Clinical guidelines advise GPs in England which patients warrant an urgent referral for suspected cancer. This study assessed how often GPs follow the guidelines, whether certain patients are less likely to be referred, and how many patients were diagnosed with cancer within 1 year of non-referral.

METHODS

We used linked primary care (Clinical Practice Research Datalink), secondary care (Hospital Episode Statistics) and cancer registration data. Patients presenting with haematuria, breast lump, dysphagia, iron-deficiency anaemia, post-menopausal or rectal bleeding for the first time during 2014-2015 were included (for ages where guidelines recommend urgent referral). Logistic regression was used to investigate whether receiving a referral was associated with feature type and patient characteristics. Cancer incidence (based on recorded diagnoses in cancer registry data within 1 year of presentation) was compared between those receiving and those not receiving referrals.

RESULTS

48 715 patients were included, of which 40% (n=19 670) received an urgent referral within 14 days of presentation, varying by feature from 17% (dysphagia) to 68% (breast lump). Young patients (18-24 vs 55-64 years; adjusted OR 0.20, 95% CI 0.10 to 0.42, p<0.001) and those with comorbidities (4 vs 0 comorbidities; adjusted OR 0.87, 95% CI 0.80 to 0.94, p<0.001) were less likely to receive a referral. Associations between patient characteristics and referrals differed across features: among patients presenting with anaemia, breast lump or haematuria, those with multi-morbidity, and additionally for breast lump, more deprived patients were less likely to receive a referral. Of 29 045 patients not receiving a referral, 3.6% (1047) were diagnosed with cancer within 1 year, ranging from 2.8% for rectal bleeding to 9.5% for anaemia.

CONCLUSIONS

Guideline recommendations for action are not followed for the majority of patients presenting with common possible cancer features. A significant number of these patients developed cancer within 1 year of their consultation, indicating scope for improvement in the diagnostic process.

'I guess I'll wait to hear'- communication of blood test results in primary care a qualitative study

BACKGROUND

Rates of blood testing in primary care are rising. Communicating blood test results generates significant workload for patients, GPs, and practice staff.

AIM

To explore GPs' and patients' experience of systems of blood test communication.

DESIGN AND SETTING

Qualitative interviews with patients and GPs in UK primary care in both urban and rural practices in the West of England.

METHOD

A total of 28 patients and 19 GPs from six practices were recruited, with a range of socioeconomic and demographic characteristics. Patients were interviewed at two time points: a) at or soon after their blood test and b) after they had received their test results. The GPs who requested the tests were also interviewed (they could complete a maximum of two interviews about different patients). Eighty qualitative interviews were undertaken; 54 patient interviews and 26 GP interviews.

RESULTS

Methods of test result communication varied between doctors and were based on habits, unwritten heuristics, and personal preferences rather than protocols. Doctors expected patients to know how to access their test results. In contrast, patients were often uncertain and used guesswork to decide when and how to access their tests. Patients and doctors generally assumed that the other party would make contact, with potential implications for patient safety. Text messaging and online methods of communication have benefits, but were perceived by some patients as 'flippant' or 'confusing'. Delays and difficulties obtaining and interpreting test results can lead to anxiety and frustration for patients.

CONCLUSION

Current systems of test result communication are complex and confusing, and mostly based on habits and routines rather than clear protocols. This has important implications for patient-centred care and patient safety.

Analysis of prescribing error and pharmacist's intervention on obstetrics and gynaecology outpatient prescriptions in a Malaysian tertiary hospital

Prescribing error in obstetrics and gynaecology (O&G) poses harm to women and potentially to the foetus and new born. Pharmacists' interventions have been reported to prevent prescribing error from reaching the patients. Little is reported on the magnitude of prescribing error and pharmacist intervention in a subspecialised outpatient O&G setting. This study aimed to identify the prevalence of prescribing error and pharmacists' interventions at the O&G outpatient setting. This retrospective study involved screening of prescriptions for commission and omission errors. Acceptance, clinical significance and rationale for pharmacists' interventions were analysed. Of the 3883 prescriptions screened, 359 (9.2%) prescriptions contained prescribing error, mainly (52.4%) due to commission errors. Among the 395 interventions performed by the pharmacists, 207 (52.4%) were recorded for omission errors. All the interventions were accepted by the prescribers with 65.1% were categorised as 'very significant'. About 54% of the interventions were conducted to optimise treatment outcome. The prevalence of prescribing error and pharmacists' interventions on O&G outpatient prescriptions was found to be substantial in this study. Standard prescription writing guideline should be routinely regulated, monitored and educated among healthcare professionals. Impact StatementWhat is already known on this subject? Prescribing error rate in O&G was found lowest in outpatient setting as compared to inpatient and high risk settings. Pharmacists' intervention performed at the centralised inpatient pharmacy unit or on-ward has shown to reduce prescribing error in inpatient settings.What do the results of this study add? This study identified that the prescribing error rate in a subspecialised outpatient O&G setting was within the range reported in high risk O&G settings. The number of prescriptions to pharmacists' intervention ratio of 9.8:1 was reported.What are the implications of these findings for clinical practice and/or further research? Further research, preferably qualitative in nature, is recommended to explore, identify and address the factors that may hinder clear, accurate and complete prescription writing practices.

The Personal and Professional Impact of Patients' Complaints on Doctors-A Qualitative Approach

Background: Complaints regarding medical practice represent a harsh reality of the current world. Patients have the right to receive explanations and compensation when they are injured during the medical act, but the increased potential for exposure to complaints determines personal and professional consequences for the doctors, with significant impact on their health and practice. Thus, the aim of our research was to analyze in depth the impact of complaints on the doctors involved. Materials and methods: The authors conducted a qualitative study, using a semi-structured interview, addressed to doctors who had complaints from patients. The participants in our research were identified using an adapted version of the snowball method. Results: After the analysis of the interviews using the inductive method, nine themes resulted, seven of which are addressed in this paper: injustice, personal impact, professional impact, difficulties, supportive factors, the attitude of the hospital management and the attitude of colleagues. At the personal level, the doctors were overwhelmed by insomnia, nightmares, stress and anxiety, and at the professional level by doubts about medical decisions, fear, anxiety and the tendency to avoid patients with severe diseases. Conclusions: The study revealed that physicians who had complaints from patients are deeply affected by the complaint itself and the associated investigation procedure, even if, to a lesser extent, some of the participants found motivation for a better management of the situation. The study also showed the need for changes in the legal and medical systems in order to create mechanisms to support the doctors during the investigation process.

Improving Patient Safety in Public Hospitals: Developing Standard Measures to Track Medical Errors and Process Breakdowns

OBJECTIVE

The aim of the study was to develop standards for tracking patient safety gaps in ambulatory care in safety net health systems.

METHODS

Leaders from five California safety net health systems were invited to participate in a modified Delphi process sponsored by the Safety Promotion Action Research and Knowledge Network (SPARKNet) and the California Safety Net Institute in 2016. During each of the three Delphi rounds, the feasibility and validity of 13 proposed patient safety measures were discussed and prioritized. Surveys and transcripts from the meetings were analyzed to understand the decision-making process.

RESULTS

The Delphi process included eight panelists. Consensus was reached to adopt 9 of 13 proposed measures. All 9 measures were unanimously considered valid, but concern was expressed about the feasibility of implementing several of the measures.

CONCLUSIONS

Although safety net health systems face high barriers to standardized measurement, our study demonstrates that consensus can be reached on acceptable and feasible methods for tracking patient safety gaps in safety net health systems. If accompanied by the active participation key stakeholder groups, including patients, clinicians, staff, data system professionals, and health system leaders, the consensus measures reported here represent one step toward improving ambulatory patient safety in safety net health systems.

The status of medical malpractice litigations in Saudi Arabia: Analysis of the annual report

Context:

Medical malpractice is a leading cause of morbidity and mortality worldwide. Analyzing the current number of lawsuits and comparing it to previous years will help assess the status of medical malpractice litigations in Saudi Arabia.

Subjects and Methods:

A review and analysis of the annual statistics book of the Medico-Legal Committees (MLCs) in Saudi Arabia over the years (1437–1439 H) was conducted.

Results:

Over the 3-year study period, the total number of lawsuits was 3,684. The percentage of increase of malpractice lawsuits from 1437 until 1439 Hijri (2016–2018) was 26% (1,097–1,379 lawsuits). Obstetrics and Gynecology consistently had the highest number lawsuits compared to other specialties (25.6%), followed by dentistry (13.5%). Similarly, the rate of compensation after a lawsuit was highest in Obstetrics and Gynecology claims (62.7%), followed by dentistry (60%). The private healthcare sector consistently showed the highest number of lawsuits when compared to other healthcare providers, with a 73% increase over 3 years. The Ministry of Health showed an overall reduction in the number of lawsuits by 6.6% over the course of the study period.

Conclusions:

The number of lawsuits in Saudi Arabia is increasing rapidly. Understanding the reason for this is very important especially given the high rates of lawsuits for certain specialties and healthcare sectors. A root cause analysis cannot be conducted without a detailed reporting system for malpractice lawsuits; the development of which would help in research and the generation of solutions in this field.

Factors associated with potentially missed acute deterioration in primary care: cohort study of UK general practices

Background

In the UK, while most primary care contacts are uncomplicated, safety incidents do occur and result in patient harm, for example, failure to recognise a patient’s deterioration in health.

Aim

To determine the patient and healthcare factors associated with potentially missed acute deterioration in health.

Design and setting

Cohort of patients registered with English Clinical Practice Research Datalink general practices between 1 April 2014 and 31 December 2017 with linked hospital data.

Method

A potentially missed acute deterioration was defined as a patient having a self-referred admission to hospital having been seen in primary care by a GP in the 3 days beforehand. All diagnoses and subsets of commonly-reported missed conditions were analysed..

Results

A total of 116 097 patients contacted a GP 3 days before an emergency admission. Patients with sepsis (adjusted odds ratio [aOR] 1.09, 95% confidence interval [CI] = 1.01 to 1.18) or urinary tract infections (aOR 1.09, 95% CI = 1.04 to 1.14) were more likely to self-refer. The duration of GP appointments was associated with self-referral. On average, a 5-minute increase in appointment time resulted in a 10% decrease in the odds of self-referred admissions (aOR 0.90, 95% CI = 0.89 to 0.91). Patients having a telephone consultation (compared with face-to-face consultation) (aOR 1.14, 95% CI = 1.11 to 1.18) previous health service use, and presence of comorbidities were also associated with self-referred admission.

Conclusion

Differentiating acute deterioration from self-limiting conditions can be difficult for clinicians, particularly in patients with sepsis, urinary tract infections, or long-term conditions. The findings of this study support the call for longer GP consultations and caution against reliance on telephone consultations in primary care; however, more research is needed to understand the underlying mechanisms.

Doctors in Chinese public hospitals: demonstration of their professional identities

BACKGROUND

An increase in the number of medical disputes and violence against doctors indicates a lack of trust in the medical profession by society in Chinese public hospitals. Empirical evidence confirms that one cause is the lack of professional identity demonstrated by doctors. Medical professionals are required to maintain high standards of competence and moral responsibility, and demonstrate qualities such as respect, compassion, integrity, responsiveness to needs, and commitment to sound ethical practice in order to maintain professional privilege. These principles and appropriate professional conduct are the foundation of the professional identity of the medical profession.

METHODS

A quantitative approach was adopted by distributing paper-based questionnaires to doctors and patients in two hospitals (Level III and Level II) in Jinan, Shandong province, China.

FINDINGS

In total, 614 doctors and 1184 inpatients on discharge from the surgical and internal medicine units of the two hospitals participated in the survey yielding 90% response rates. The study confirmed the variation amongst doctors in demonstrating their professionalism in terms of respecting patients' views and preferences when determining diagnostic procedures and treatment plans, and when making ethical decisions. Although 90% patients indicated that they showed respects to doctors, close to 20% of the doctors disagreed that they received high respect from patients. About 12% of doctors prescribed unnecessary diagnostic procedures to patient for the purpose of generating profit and more than 20% of patients indicated that they gave gifts to doctors in order to receive better treatment.

CONCLUSIONS

Although about 80% of doctors demonstrated certain aspects of professionalism required by practitioners, the inconsistency across the medical workforce may exacerbate tense doctor-patient relationships. A review of medical curricula and focus of the internship program is required in order to assist medical graduates with forming required professional identity in order to improve patient satisfaction and better clinical outcomes. To be effective, a more systematic approach is recommended.

Breakdowns in the initial patient-provider encounter are a frequent source of diagnostic error among ischemic stroke cases included in a large medical malpractice claims database

Background Misdiagnosis of dangerous cerebrovascular disease is a substantial public health problem. We sought to identify and describe breakdowns in the diagnostic process among patients with ischemic stroke to facilitate future improvements in diagnostic accuracy. Methods We performed a retrospective, descriptive study of medical malpractice claims housed in the Controlled Risk Insurance Company (CRICO) Strategies Comparative Benchmarking System (CBS) database from 1/1/2006 to 1/1/2016 involving ischemic stroke patients. Baseline claimant demographics, clinical setting, primary allegation category, and outcomes were abstracted. Among cases with a primary diagnosis-related allegation, we detail presenting symptoms and diagnostic breakdowns using CRICO's proprietary taxonomy. Results A total of 478 claims met inclusion criteria; 235 (49.2%) with diagnostic error. Diagnostic errors originated in the emergency department (ED) in 46.4% (n = 109) of cases, outpatient clinic in 27.7% (n = 65), and inpatient setting in 25.1% (n = 59). Across care-settings, the most frequent process breakdown was in the initial patient-provider encounter [76.2% (n = 179 cases)]. Failure to assess, communicate, and respond to ongoing symptoms was the component of the patient-provider encounter most frequently identified as a source of misdiagnosis in the ED. Exclusively non-traditional presenting symptoms occurred in 35.7% (n = 84), mixed traditional and non-traditional symptoms in 30.6% (n = 72), and exclusively traditional in 23.8% (n = 56) of diagnostic error cases. Conclusions Among ischemic stroke patients, breakdowns in the initial patient-provider encounter were the most frequent source of diagnostic error. Targeted interventions should focus on the initial diagnostic encounter, particularly for ischemic stroke patients with atypical symptoms.

Frequency, Recognition, and Potential Risk Factors of Incidental Findings on Trauma Computed Tomography Scans: A Cross-Sectional Study at an Urban Level One Trauma Center

Background

Computed tomography (CT) use in injured patients has continuously increased in the past decades. We designed and undertook this study to evaluate the frequency, and potential risks of incidental findings (IFs), and how they were processed in trauma patients receiving CT scans.

Methods

We retrospectively reviewed CT scans, official CT reports, and basic demographics in trauma patients who received CT scans at our emergency department in 2016. Scans with IFs prompted a detailed review of medical records to determine clinical significance and how they were processed. IFs were classified into three categories: category I (potentially severe condition, in-time management required), category II (not urgent, follow-up needed), and category III (of minor concern). Multivariable logistic regression models were fitted to determine patient characteristics associated with IFs.

Results

In the 4,092 scans enrolled, IFs were identified in 649 (15.9%). There were 13 (2.0%) category I, 306 (47.2%) category II, and 330 (50.8%) category III IFs. Patients with IFs were older than those without. No sex-based difference was found. Most (61.5%) of the scans were performed for the head; however, the abdomen had the highest IF prevalence (26.2%). Documentation about IFs was poor; 31% of category I, 91.9% of category II, and 97.0% of category III have no related record. Old age remains the risk predicting the presence of IFs, and every year of increasing age was independently associated with a higher prevalence of IFs (OR: 1.019; 95% CI: 1.015-1.024).

Conclusions

IFs are common in trauma CT scans; however, recognition and management remain poor. Abdomen and chest scans, and CT in older patients should remind us of increasing risks of IFs.

A systematic review of patient complaints about general practice

BACKGROUND

Health care complaints are an underutilized resource for quality and safety improvement. Most research on health care complaints is focused on secondary care. However, there is also a need to consider patient safety in general practice, and complaints could inform quality and safety improvement.

OBJECTIVE

This review aimed to synthesize the extant research on complaints in general practice.

METHODS

Five electronic databases were searched: Medline, Web of Science, CINAHL, PsycINFO and Academic Search Complete. Peer-reviewed studies describing the content, impact of and motivation for complaints were included and data extracted. Framework synthesis was conducted using the Healthcare Complaints Analysis Tool (HCAT) as an organizing framework. Methodological quality was appraised using the Quality Assessment Tool for Studies with Diverse Designs (QATSDD).

RESULTS

The search identified 2960 records, with 21 studies meeting inclusion criteria. Methodological quality was found to be variable. The contents of complaints were classified using the HCAT, with 126 complaints (54%) classified in the Clinical domain, 55 (23%) classified as Management and 54 (23%) classified as Relationships. Motivations identified for making complaints included quality improvement for other patients and monetary compensation. Complaints had both positive and negative impacts on individuals and systems involved.

CONCLUSION

This review highlighted the high proportion of clinical complaints in general practice compared to secondary care, patients' motivations for making complaints and the positive and negative impacts that complaints can have on health care systems. Future research focused on the reliable coding of complaints and their use to improve quality and safety in general practice is required.

Health Technology Assessment for Vaccines Against Rare, Severe Infections: Properly Accounting for Serogroup B Meningococcal Vaccination's Full Social and Economic Benefits

The high price of new generations of vaccines relative to their predecessors has become an important consideration in debates over whether the benefits of the new vaccines justify their costs. An increasingly central line of inquiry in the literature on valuing vaccination surrounds accounting for the full social and economic benefits of vaccination. This paper applies this emerging perspective to the particular case of vaccination against serogroup B meningococcal disease (MenB). We explore key issues involved in health technology assessments of MenB vaccination, which have led to pronounced heterogeneity in evaluation methods and recommendation outcomes across countries such as France, Germany, the US, and the UK. Accounting for typically neglected sources of socioeconomic benefit could potentially impact recommendation and reimbursement decisions. We propose a taxonomy of such benefits built around four dimensions: (i) internalized health benefits, (ii) internalized non-health benefits, (iii) externalized health benefits, and (iv) externalized non-health benefits. This approach offers a systematic, comprehensive evaluation framework that can be used in future assessment of MenB vaccines as well as other health technologies.

Consistency of safety monitoring using routine national databases: results using a quality of care interpretative model

Background

In the framework of targeted action for continuous safety monitoring, we aimed to evaluate the consistency of indicators derived from available databases for regular reporting.

Methods

We used a quality of care interpretative model to select characteristics from five national databases, aggregated and linked by homogeneous groups of providers. The target population included all subjects admitted to public hospitals for acute care in four regions of Italy between 2011 and 2013. The association between structures, processes and safety-related outcomes was investigated using odds ratios from generalized estimating equations logistic regression. Outcome measures included claims of malpractice and five patient safety indicators calculated from discharge abstracts using standardized algorithms.

Results

Over 3 years, claims of malpractice and sepsis increased, whereas deep vein thrombosis and pulmonary embolism decreased. Hospitals with high vs. low volume of discharges were associated with −16% lower rates of claims, but +12% increased risk of sepsis. Compared with research institutes, university clinics had −17% lower rates of claims and −41% cases of dehiscence, with a +32% increased risk of deep vein thrombosis. Local health care authorities recorded −49% deep vein thrombosis, −26% pulmonary embolism, −40% sepsis and +37% risk of claims. Hospitals submitting cases of safe practices and implementing safety recommendations showed significantly higher rates for most outcome measures.

Conclusions

Indicators from regular databases can be conveniently used to develop a national safety monitoring system for hospital care. Although deeper analysis is needed, institutions with a higher propensity to implement safe practices and recommendations consistently showed higher rates of adverse events.

Reasons for and Facilitating Factors of Medical Malpractice Complaints. What Can Be Done to Prevent Them?

Background and objectives. Medical malpractice is an increasing phenomenon all over the world, and Romania is not spared. This matter is of concern as it has a significant impact on the physicians and the patients involved, as well as on the health care system and society in general. The purpose of our study was to perform an insight analysis on the reasons for medical malpractice complaints as well as the factors that facilitate the complaints to identify specific ways to prevent them and, implicitly, to improve the medical practice. Materials and Methods. The authors conducted a retrospective study of the medical malpractice complaints registered in the period 2006–2019 at the Commission for monitoring and professional competence for malpractice cases in the region of Moldova, Romania, collecting data on both the patients and the medical professionals involved. Results. The authors analyzed 153 complaints directed against 205 medical professionals and identified 15 categories of reasons for complaints, the most significant being related to the occurrence of complications, and to the doctor–patient interaction (e.g., communication, behavior, informed consent). The most frequently reported medical specialties were obstetrics and gynecology, emergency medicine, general surgery, and orthopedics and traumatology. Emergency medicine was often involved in complaints suggesting an over utilization of this department in our country and the need for health policies, which could divert the large number of patients accessing emergency medicine towards primary care. Conclusions. Regarding the dysfunctions in the doctor–patient relationship frequently claimed by patients, the authors concluded that doctors need special undergraduate training and periodic updating during their practice for them to be able to adequately address the challenges of interacting with their patients.

MicroRNA Ratios Distinguish Melanomas from Nevi

The use of microRNAs as biomarkers has been proposed for many diseases, including the diagnosis of melanoma. Although hundreds of microRNAs have been identified as differentially expressed in melanomas as compared to benign melanocytic lesions, a limited consensus has been achieved across studies, constraining the effective use of these potentially useful markers. In this study, we applied a machine learning-based pipeline to a dataset consisting of genetic features, clinical features, and next-generation microRNA sequencing from micro-dissected formalin-fixed paraffin embedded melanomas and their adjacent benign precursor nevi. We identified patient age and tumor cellularity as variables that frequently confound the measured expression of potentially diagnostic microRNAs. By employing the ratios of microRNAs that were either enriched or depleted in melanoma compared to the nevi as a normalization strategy, we developed a model that classified all the available published cohorts with an area under the receiver operating characteristic curve of 0.98. External validation on an independent cohort classified lesions with 81% sensitivity and 88% specificity and was uninfluenced by the tumor content of the sample or patient age.

Measures to Improve Diagnostic Safety in Clinical Practice

Timely and accurate diagnosis is foundational to good clinical practice and an essential first step to achieving optimal patient outcomes. However, a recent Institute of Medicine report concluded that most of us will experience at least one diagnostic error in our lifetime. The report argues for efforts to improve the reliability of the diagnostic process through better measurement of diagnostic performance. The diagnostic process is a dynamic team-based activity that involves uncertainty, plays out over time, and requires effective communication and collaboration among multiple clinicians, diagnostic services, and the patient. Thus, it poses special challenges for measurement. In this paper, we discuss how the need to develop measures to improve diagnostic performance could move forward at a time when the scientific foundation needed to inform measurement is still evolving. We highlight challenges and opportunities for developing potential measures of "diagnostic safety" related to clinical diagnostic errors and associated preventable diagnostic harm. In doing so, we propose a starter set of measurement concepts for initial consideration that seem reasonably related to diagnostic safety and call for these to be studied and further refined. This would enable safe diagnosis to become an organizational priority and facilitate quality improvement. Health-care systems should consider measurement and evaluation of diagnostic performance as essential to timely and accurate diagnosis and to the reduction of preventable diagnostic harm.

An analysis of general practitioners' perspectives on patient safety incidents using critical incident technique interviews

BACKGROUND

General practitioners report difficulty in knowing how to improve patient safety.

OBJECTIVES

To analyse general practitioners' perspectives of contributing factors to patient safety incidents by collecting accounts of incidents, identifying the contributory factors to these incidents, assessing the impact and likelihood of occurrence of these incidents and examining whether certain categories of contributory factors were associated with the occurrence of high-risk incidents.

METHODS

Critical incident technique interviews were carried out with 30 general practitioners in Ireland about a patient safety incident they had experienced. The Yorkshire Contributory Factors Framework was used to classify the contributory factors to incidents. Seven subject matter experts rated the impact and likelihood of occurrence of each incident.

RESULTS

A total of 26 interviews were analysed. Almost two-thirds of the patient safety incidents were rated as having a major-to-extreme impact on the patient, and over a third were judged as having at least a bimonthly likelihood of occurrence. The most commonly described active failures were 'Medication Error' (34.6%) and 'Diagnostic Error' (30.8%). 'Situational Domain' was identified as a contributory domain in all patient safety incidents. 'Communication' breakdown at both practice and other healthcare-provider interfaces (69.2%) was also a commonly cited contributory factor. There were no significant differences in the levels of risk associated with the contributory factors.

CONCLUSIONS

Critical incident technique interviews support the identification of contributory factors to patient safety incidents. There is a need to explore the use of the resulting data for quality and safety improvement in general practice.

Adverse drug reactions in primary care: a scoping review protocol

REVIEW QUESTION/OBJECTIVE

The objective of the scoping review is to examine the types of adverse drug reactions experienced by patients in the primary care setting and to map the classes of medications associated with adverse drug reactions.

Patient Harm in Cataract Surgery: A Series of Adverse Events in Massachusetts

Massachusetts state agencies received reports of 37 adverse events (AEs) involving cataract surgery from 2011 to 2015. Fifteen were anesthesia related, including 5 wrong eye blocks, 3 cases of hemodynamic instability, 2 retrobulbar hematoma/hemorrhages, and 5 globe perforations resulting in permanent loss of vision. While Massachusetts' reported AEs likely underrepresent the true number of AEs that occur during cataract surgery, they do offer useful signal data to indicate the types of patient harm occurring during these procedures.

Electronic Health Record-Related Events in Medical Malpractice Claims

BACKGROUND

There is widespread agreement that the full potential of health information technology (health IT) has not yet been realized and of particular concern are the examples of unintended consequences of health IT that detract from the safety of health care or from the use of health IT itself. The goal of this project was to obtain additional information on these health IT-related problems, using a mixed methods (qualitative and quantitative) analysis of electronic health record-related harm in cases submitted to a large database of malpractice suits and claims.

METHODS

Cases submitted to the CRICO claims database and coded during 2012 and 2013 were analyzed. A total of 248 cases (<1%) involving health IT were identified and coded using a proprietary taxonomy that identifies user- and system-related sociotechnical factors. Ambulatory care accounted for most of the cases (146 cases). Cases were most typically filed as a result of an error involving medications (31%), diagnosis (28%), or a complication of treatment (31%). More than 80% of cases involved moderate or severe harm, although lethal cases were less likely in cases from ambulatory settings. Etiologic factors spanned all of the sociotechnical dimensions, and many recurring patterns of error were identified.

CONCLUSIONS

Adverse events associated with health IT vulnerabilities can cause extensive harm and are encountered across the continuum of health care settings and sociotechnical factors. The recurring patterns provide valuable lessons that both practicing clinicians and health IT developers could use to reduce the risk of harm in the future. The likelihood of harm seems to relate more to a patient's particular situation than to any one class of error.

Canadian and UK/Ireland practice patterns in lumbar puncture performance in febrile neonates with bronchiolitis

BACKGROUND

Serious bacterial infections in young infants with bronchiolitis are rare. Febrile infants <1 month old with bronchiolitis often receive a lumbar puncture (LP), despite limited data for this practice and lack of clinical practice guidelines for this population. The primary objective was to investigate practice patterns in performance of LPs in the ED management of febrile infants aged ≤30 days with bronchiolitis.

METHODS

A cross-sectional survey of two national paediatric emergency research networks (PediatricEmergency Research Canada (PERC) and the PediatricEmergency Research UK/Ireland (PERUKI)) was conducted January to November 2017 using a modified Dillman technique. The survey was preceded by a clinical vignette describing a well appearing, 21-day-old infant with low-grade fever, respiratory findings typical of bronchiolitis and no perinatal serious bacterial infection (SBI) risk features.

RESULTS

The response rate from PERC was 169/250 (68%) and 172/201 (86%) from PERUKI. Nine physicians in training were excluded, leaving 332 eligible participants. Although most physicians believe that neonates with bronchiolitis rarely have meningitis (PERC 141/161 (87.6%); PERUKI 154/171 (90%)) and feel comfortable diagnosing bronchiolitis in this group (PERC 136/161 (84.5%); PERUKI 143/171 (83.6%)), there was significant variation in the proportion who would be likely/very likely to perform an LP (PERC 100/161 (62.1%); PERUKI 15/171 (8.8%)) (p<0.0001). Practice in Canada, <10 years in practice and lack of comfort with diagnosing bronchiolitis represent multivariable predictors of LP; OR 23.7 (95% CI 11.7 to 47.9), 2.3 (95% CI 1.2 to 4.2) and 2.5 (95% CI 1.1 to 5.0), respectively. Rapid knowledge of respiratory syncytial virus positivity would decrease LP probability from 35.4% to 20.2%.

CONCLUSION

Estimated probability of performing LPs and other interventions in otherwise healthy febrile neonates with bronchiolitis is highly variable between emergency physicians in Canada and the UK/Ireland. Network, <10 years in ED practice and comfort level with diagnosing bronchiolitis in newborns constitute independent predictors of the likelihood of LP performance.

Potential value of patient record review to assess and improve patient safety in general practice: A systematic review

Background: There is limited research, and guidance, on how to address safety in general practice proactively.

Objectives: This review aimed to synthesize the literature describing the use of patient record review (PRR) to measure and improve patient safety in primary care. The PRR methodologies utilized and the resulting outcomes were examined.

Methods: Searches were conducted using Medline, Embase, CINAHL and PsycINFO in February 2017. Reference lists of included studies and existing review papers were also screened. English language, peer-reviewed studies that utilized PRR to identify patient safety incidents (PSIs) occurring in general practice were included. Two researchers independently extracted data from articles and applied the Quality Assessment Tool for Studies with Diverse Designs.

Results: A total of 3265 studies were screened, with 15 included. Trigger tools were the most frequent method used for the PRRs (n = 6). The mean number of safety incidents per 100 records was 12.6. Within studies, a mean of 30.6% of incidents were associated with severe harm (range 8.6–50%), and a mean of 55.6% of incidents was considered preventable (range 32.7–93.5%). The most commonly identified types of PSIs related to medication and prescribing, diagnosis, communication and treatment. Three studies reported on improvement actions taken after the PRRs.

Conclusion: This review suggests that PRR may be a promising means of proactively identifying patient safety incidents and informing improvements.

Medical Data Management on Blockchain with Privacy

Medical data are important in diagnosis, treatment, recovery, and medical accident investigation. The integrity and availability of medical data are the basic guarantee for the smooth operation of these activities. The privacy of medical data is a natural demand from the sensitivity of medical data. At present, there are mainly two ways to protect the privacy of medical data. One way is to store medical data in a local database and set up an access control strategy of the database. The other way is to encrypt medical data with the patient's key and to share the key when needed. The problem with the first method is that the data in the local database may be modified or deleted. The problem with the second method is that the key cannot be shared when the patient dies during the diagnosis and treatment. These two problems will damage the availability of data. This paper proposes to establish a shared key that could be reconstructed by the legitimate parties before the process of diagnosis and treatment begins. The data in the diagnosis and treatment process is encrypted and stored in a blockchain using the shared key. The proposal meets the integrity, availability and privacy requirements of medical data. It uses the sibling intractable function families (SIFF) to establish a shared key, and uses the Hyperledger Fabric to store encrypted data. The simulation shows that the system has good efficiency. Additionally, it is the first time to introduce SIFF to a blockchain application.

Characterising patient complaints in out-of-hours general practice: a retrospective cohort study in Ireland

BACKGROUND

Patient complaints can provide valuable insights into the quality and safety of clinical care. Studies examining the epidemiology of complaints in out-of-hours general practice internationally are limited.

AIM

To characterise patient complaints in an out-of-hours general practice setting.

DESIGN AND SETTING

Retrospective cohort study of patient complaints to an out-of-hours service provider in Dublin, Ireland, over a 5-year period (2011-2016). This comprises nurse-led telephone triage and GP consultations for patients with urgent problems.

METHOD

A modified version of the UK Healthcare Complaints Analysis Tool (HCAT) was utilised to code complaints, which were reviewed independently in duplicate by two academic GPs.

RESULTS

Of 445 598 telephone contacts, 303 085 resulted in face-to-face GP consultations. Of 234 patients who made 298 complaints, 185 (79%) related to GP care. The remainder related to nurse triage, other staff, and management issues. A total of 109 (46%) related to children aged ≤18 years, and 134 (58%) of complainants were female. There were 0.61 complaints per 1000 GP consultations. Most complaints (n = 126, 42%) were in relation to clinical care problems, largely diagnosis and prescribing. Common themes included unmet management expectations and clinical examination dissatisfaction. Inter-rater reliability was 90% (κ statistic 0.84, 95% confidence interval = 0.80 to 0.88). Following internal investigation, 158 (85%) of GP-related complaints were managed effectively by the out-of-hours service.

CONCLUSION

The majority of complaints related to clinical care problems and were successfully managed locally. Expectation management may be an important way to mitigate the risk of complaints.

Evidence of a positive association between malpractice climate and thyroid cancer incidence in the United States

The incidence of thyroid cancer has risen dramatically in the past few decades. The cause of this is unclear, but several lines of evidence indicate it is largely due to overdiagnosis, the diagnosis of tumors that would have never manifest clinically if untreated. Practices leading to overdiagnosis may relate to defensive medicine. In this study, we evaluated the association between malpractice climate and incidence of thyroid, breast, prostate, colon, and lung cancer in U.S. states from 1999-2012 using publicly available government data. State-level malpractice risk was quantified as malpractice payout rate, the number of malpractice payouts per 100,000 people per state per year. Associations between state-level cancer incidence, malpractice payout rate, and several cancer risk factors were evaluated. Risk factors included several social determinants of health, including factors predicting healthcare access. States with higher malpractice payout rate had higher thyroid cancer incidence, on both univariate analysis (r = 0.51, P = 0.009, Spearman) and multivariate analysis (P<0.001, multilevel model). In contrast, state-level malpractice payout rate was not associated with incidence of any other cancer type. Malpractice climate may be a social determinant for being diagnosed with thyroid cancer. This may be a product of greater defensive medicine in states with higher malpractice risk, which leads to increased diagnostic testing of patients with thyroid nodules and potential overdiagnosis. Alternatively, malpractice risk may be a proxy for another, unmeasured risk factor.

The Characteristics of Physicians Who are Re-Disciplined by Medical Boards: A Retrospective Cohort Study

BACKGROUND

Physician misconduct adversely affects patient safety and is therefore of societal importance. Little work has specifically examined re-disciplined physicians. A study was conducted to compare the characteristics of re-disciplined to first-time disciplined physicians.

METHODS

A retrospective review of Canadian physicians disciplined by medical boards between 2000 and 2015 was conducted. Physicians were divided into those disciplined once and those disciplined more than once. Differences in demographics, transgressions, and penalties were evaluated.

RESULTS

There were 938 disciplinary events for 810 disciplined physicians with 1 in 8 (n = 101, 12.5%) being re-disciplined. Re-disciplined physicians had up to six disciplinary events in the study period and 4 (4.0%) had events in more than one jurisdiction. Among those re-disciplined, 94 (93.1%) were male, 34 (33.7%) were international medical graduates, and 88 (87.1%) practiced family medicine (n = 59, 58.4%), psychiatry (n = 11, 10.9%), surgery (n = 9, 8.9%), or obstetrics/gynecology (n = 9, 8.9%). The proportion of obstetrician/gynecologists was higher among re-disciplined physicians (8.9% vs. 4.2%, p = 0.048). Re-disciplined physicians had more mental illness (1.7% vs. 0.1%, p = 0.01), unlicensed activity (19.2% vs. 7.2%, p <0.01), and less sexual misconduct (20.1% vs. 27.9%, p = 0.02). License suspension occurred more frequently among those re-disciplined (56.8% vs. 48.0%, p = 0.02) as did license restriction (38.4% vs. 26.7%, p <0.01). License revocation was not different between cohorts (10.9% vs. 13.5%, p = 0.36).

CONCLUSION

Re-discipline is not uncommon and underscores the need for better identification of at-risk individuals and optimization of remediation and penalties. The distribution of transgression argues for a national disciplinary database that could improve communication between jurisdictional medical boards.

Qualitative evaluation of an educational intervention to reduce medicolegal risks for medical doctors experiencing significantly more cases than their peers in the UK and Ireland

OBJECTIVES

The Medical Protection Society (MPS) is a leading protection organisation for healthcare professionals worldwide. In the UK and Ireland, a small minority of MPS members experience significantly more medicolegal cases than their peers and are invited to participate in a risk education (RE) remediation process. To understand more about this educational intervention, we sought to explore participating doctors' views of their experiences of this process and identify self-reported performance improvements and what elements of the intervention could be improved.

DESIGN

Qualitative semistructured telephone interviews with a convenience sample of doctors with significantly more medicolegal cases than their peers identified by MPS.

SETTING

UK and Ireland MPS members.

PARTICIPANTS

A convenience sample of 20 general medical practitioners and hospital specialists from a total of 79 who completed the RE process (25.3% response rate), with a particular focus on the Member Risk Review programme, between November 2013 and October 2015.

RESULTS

19 participants were male and 16 were based in general medical (office) practice. Three key themes were generated: personal and professional impacts and actions (eg, member has taken action to reduce clinical workload); comprehension and validity of RE interventions (eg, risks were related to wider patient management); and feedback and proposals (eg, the supportive nature of the educational interventions should be clear from the start). A number of recommendations were made by participants to improve the RE process and enhance the educational experience.

CONCLUSIONS

The RE process was largely valued by participants with many reporting that participation led to some positive professional behaviour changes and improvements in practice processes and personal well-being.

Cancer screening recommendations: an international comparison of high income countries

Background

Recommendations regarding cancer screening vary from country to country, and may also vary within countries depending on the organization making the recommendations. The goal of this study was to summarize the cancer screening recommendations from the 21 countries with the highest per capita spending on healthcare.

Main body

Cancer screening guidelines were identified for each country based on a review of the medical literature, internet searches, and contact with key informants in most countries. The highest level recommendation was identified for each country, in the order of national recommendation, cancer society recommendation, or medical specialty society recommendation. Breast cancer screening recommendations were generally consistent across countries, most commonly recommending mammography biennially from ages 50 to 69 or 70 years. In the USA, specialty societies generally offered more intensive screening recommendations. All countries also recommend cervical cancer screening, although there is some heterogeneity regarding the test (cytology or HPV or both) and the age of initiation and screening interval. Most countries recommend colorectal cancer screening using fecal immunochemical (FIT) testing, while only seven countries recommend general or selective screening for prostate cancer, and a similar number explicitly recommend against screening for prostate cancer. Screening for lung and skin cancer is only recommended by a few countries. Greater per capita healthcare expenditures are not associated with greater screening intensity, with the possible exception of prostate cancer.

Conclusions

Guidelines for cancer screening differ between countries, with areas of commonality but also clear differences. Recommendations have important commonalities for well-established cancer screening programs such as breast and cervical cancer, with greater variation between countries regarding prostate, colorectal, lung, and skin cancer screening. Ideally, recommendations should be made by a professionally diverse, independent panel of experts that make evidence-based recommendations regarding screening based on the benefits, harms, and available resources in that country’s context.

A 12-year analysis of closed medical malpractice claims of the Taiwan civil court: A retrospective study

Malpractices lawsuits cause increased physician stress and decreased career satisfaction, which might result in defensive medicine for avoiding litigation. It is, consequently, important to learn experiences from previous malpractice claims. The aim of this study was to examine the epidemiologic factors related to medical malpractice claims, identify specialties at high risk of such claims, and determine clinical which errors tend to lead to medical malpractice lawsuits, by analyzing closed malpractice claims in the civil courts of Taiwan.The current analysis reviewed the verdicts of the Taiwan judicial system from a retrospective study using the population-based databank, focusing on 946 closed medical claims between 2002 and 2013.Among these medical malpractice claims, only 14.1% of the verdicts were against clinicians, with a mean indemnity payment of $83,350. The most common single specialty involved was obstetrics (10.7%), while the surgery group accounted for approximately 40% of the cases. In total, 46.3% of the patients named in the claims had either died or been gravely injured. Compared to the $75,632 indemnity for deceased patients, the mean indemnity payment for plaintiffs with grave outcomes was approximately 4.5 times higher. The diagnosis groups at high risk of malpractice litigation were infectious diseases (7.3%), malignancies (7.2%), and limb fractures (4.9%). A relatively low success rate was found in claims concerning undiagnosed congenital anomalies (4.5%) and infectious diseases (5.8%) group. A surgery dispute was the most frequent argument in civil malpractice claims (38.8%), followed by diagnosis error (19.3%).Clinicians represent 85.9% of the defendants who won their cases, but they spent an average of 4.7 years to reach final adjudication. Increased public education to prevent unrealistic expectations among patients is recommended to decrease frivolous lawsuits. Further investigation to improve the lengthy judicial process is also necessary to relieve the stress of medical malpractice claims on clinicians and practitioners, as well as on the judicial system and rightful claimants.

Twenty-five years of French jurisprudence in criminal medical liability

We report on a comprehensive 25-year study on criminal medical liability in France, undertaken to establish trends in the number of cases being brought before the criminal courts. We did this by interrogating the database on the Légifrance website using a Boolean equation (' pénal' (criminal) AND ' médecin' (physician) OR ' docteur' (doctor)). In total 539 cases were selected, in which the status of the physician either influenced the punishment imposed, or was a prerequisite for the commission of the offence. The results of the search produced two outcomes: offences and the dates of the most recent criminal judgements (which had been left blank). Further data were also collected: references to court cases, hearing dates, offence dates, procedural time limits, numbers of accused parties, types of punishments and physician characteristics. The number of court hearings increased from the 1980s until the late 1990s. Since then, it has remained stable at around 25 cases per year. Of the defendants appearing before the courts, 39.2% have been found guilty. On average, 10 to 13 physicians every year - that is, one per month - are punished. Those most often punished are obstetrician-gynaecologists (13%), followed by intensive care anaesthetists (11%) and then by general practitioners (6.7%). The offences most frequently occurring are manslaughter (36.5%), illegal profits (12%), unintentional injuries (11.5%) and sexual offences (10.1%). The results are most reassuring in terms of the risks posed by the practice of medicine in France. Such a risk does indeed exist; however, it is at a low level and stable.

Experience with Integrating Diagnostic Decision Support Software with Electronic Health Records: Benefits versus Risks of Information Sharing

Introduction:

Reducing misdiagnosis has long been a goal of medical informatics. Current thinking has focused on achieving this goal by integrating diagnostic decision support into electronic health records.

Methods:

A diagnostic decision support system already in clinical use was integrated into electronic health record systems at two large health systems, after clinician input on desired capabilities. The decision support provided three outputs: editable text for use in a clinical note, a summary including the suggested differential diagnosis with a graphical representation of probability, and a list of pertinent positive and pertinent negative findings (with onsets).

Results:

Structured interviews showed widespread agreement that the tool was useful and that the integration improved workflow. There was disagreement among various specialties over the risks versus benefits of documenting intermediate diagnostic thinking. Benefits were most valued by specialists involved in diagnostic testing, who were able to use the additional clinical context for richer interpretation of test results. Risks were most cited by physicians making clinical diagnoses, who expressed concern that a process that generated diagnostic possibilities exposed them to legal liability.

Discussion and Conclusion:

Reconciling the preferences of the various groups could include saving only the finding list as a patient-wide resource, saving intermediate diagnostic thinking only temporarily, or adoption of professional guidelines to clarify the role of decision support in diagnosis.

Requirements and validation of a prototype learning health system for clinical diagnosis

INTRODUCTION

Diagnostic error is a major threat to patient safety in the context of family practice. The patient safety implications are severe for both patient and clinician. Traditional approaches to diagnostic decision support have lacked broad acceptance for a number of well-documented reasons: poor integration with electronic health records and clinician workflow, static evidence that lacks transparency and trust, and use of proprietary technical standards hindering wider interoperability. The learning health system (LHS) provides a suitable infrastructure for development of a new breed of learning decision support tools. These tools exploit the potential for appropriate use of the growing volumes of aggregated sources of electronic health records.

METHODS

We describe the experiences of the TRANSFoRm project developing a diagnostic decision support infrastructure consistent with the wider goals of the LHS. We describe an architecture that is model driven, service oriented, constructed using open standards, and supports evidence derived from electronic sources of patient data. We describe the architecture and implementation of 2 critical aspects for a successful LHS: the model representation and translation of clinical evidence into effective practice and the generation of curated clinical evidence that can be used to populate those models, thus closing the LHS loop.

RESULTS/CONCLUSIONS

Six core design requirements for implementing a diagnostic LHS are identified and successfully implemented as part of this research work. A number of significant technical and policy challenges are identified for the LHS community to consider, and these are discussed in the context of evaluating this work: medico-legal responsibility for generated diagnostic evidence, developing trust in the LHS (particularly important from the perspective of decision support), and constraints imposed by clinical terminologies on evidence generation.

Common evidence gaps in point-of-care diagnostic test evaluation: a review of horizon scan reports

OBJECTIVE

Since 2008, the Oxford Diagnostic Horizon Scan Programme has been identifying and summarising evidence on new and emerging diagnostic technologies relevant to primary care. We used these reports to determine the sequence and timing of evidence for new point-of-care diagnostic tests and to identify common evidence gaps in this process.

DESIGN

Systematic overview of diagnostic horizon scan reports.

PRIMARY OUTCOME MEASURES

We obtained the primary studies referenced in each horizon scan report (n=40) and extracted details of the study size, clinical setting and design characteristics. In particular, we assessed whether each study evaluated test accuracy, test impact or cost-effectiveness. The evidence for each point-of-care test was mapped against the Horvath framework for diagnostic test evaluation.

RESULTS

We extracted data from 500 primary studies. Most diagnostic technologies underwent clinical performance (ie, ability to detect a clinical condition) assessment (71.2%), with very few progressing to comparative clinical effectiveness (10.0%) and a cost-effectiveness evaluation (8.6%), even in the more established and frequently reported clinical domains, such as cardiovascular disease. The median time to complete an evaluation cycle was 9 years (IQR 5.5-12.5 years). The sequence of evidence generation was typically haphazard and some diagnostic tests appear to be implemented in routine care without completing essential evaluation stages such as clinical effectiveness.

CONCLUSIONS

Evidence generation for new point-of-care diagnostic tests is slow and tends to focus on accuracy, and overlooks other test attributes such as impact, implementation and cost-effectiveness. Evaluation of this dynamic cycle and feeding back data from clinical effectiveness to refine analytical and clinical performance are key to improve the efficiency of point-of-care diagnostic test development and impact on clinically relevant outcomes. While the 'road map' for the steps needed to generate evidence are reasonably well delineated, we provide evidence on the complexity, length and variability of the actual process that many diagnostic technologies undergo.

Randomized Trial of Reducing Ambulatory Malpractice and Safety Risk: Results of the Massachusetts PROMISES Project

OBJECTIVE

Evaluate application of quality improvement approaches to key ambulatory malpractice risk and safety areas.

STUDY SETTING

In total, 25 small-to-medium-sized primary care practices (16 intervention; 9 control) in Massachusetts.

STUDY DESIGN

Controlled trial of a 15-month intervention including exposure to a learning network, webinars, face-to-face meetings, and coaching by improvement advisors targeting "3+1" high-risk domains: test result, referral, and medication management plus culture/communication issues evaluated by survey and chart review tools.

DATA COLLECTION METHODS

Chart reviews conducted at baseline and postintervention for intervention sites. Staff and patient survey data collected at baseline and postintervention for intervention and control sites.

PRINCIPAL FINDINGS

Chart reviews demonstrated significant improvements in documentation of abnormal results, patient notification, documentation of an action or treatment plan, and evidence of a completed plan (all P<0.001). Mean days between laboratory test date and evidence of completed action/treatment plan decreased by 19.4 days (P<0.001). Staff surveys showed modest but nonsignificant improvement for intervention practices relative to controls overall and for the 3 high-risk domains that were the focus of PROMISES.

CONCLUSIONS

A consortium of stakeholders, quality improvement tools, coaches, and learning network decreased selected ambulatory safety risks often seen in malpractice claims.

Diagnostic delay for giant cell arteritis - a systematic review and meta-analysis

BACKGROUND

Giant cell arteritis (GCA), if untreated, can lead to blindness and stroke. The study's objectives were to (1) determine a new evidence-based benchmark of the extent of diagnostic delay for GCA and (2) examine the role of GCA-specific characteristics on diagnostic delay.

METHODS

Medical literature databases were searched from inception to November 2015. Articles were included if reporting a time-period of diagnostic delay between onset of GCA symptoms and diagnosis. Two reviewers assessed the quality of the final articles and extracted data from these. Random-effects meta-analysis was used to pool the mean time-period (95% confidence interval (CI)) between GCA symptom onset and diagnosis, and the delay observed for GCA-specific characteristics. Heterogeneity was assessed by I ² and by 95% prediction interval (PI).

RESULTS

Of 4128 articles initially identified, 16 provided data for meta-analysis. Mean diagnostic delay was 9.0 weeks (95% CI, 6.5 to 11.4) between symptom onset and GCA diagnosis (I ² = 96.0%; P < 0.001; 95% PI, 0 to 19.2 weeks). Patients with a cranial presentation of GCA received a diagnosis after 7.7 (95% CI, 2.7 to 12.8) weeks (I ² = 98.4%; P < 0.001; 95% PI, 0 to 27.6 weeks) and those with non-cranial GCA after 17.6 (95% CI, 9.7 to 25.5) weeks (I ² = 96.6%; P < 0.001; 95% PI, 0 to 46.1 weeks).

CONCLUSIONS

The mean delay from symptom onset to GCA diagnosis was 9 weeks, or longer when cranial symptoms were absent. Our research provides an evidence-based benchmark for diagnostic delay of GCA and supports the need for improved public awareness and fast-track diagnostic pathways.
