Diagnostic Imaging: Appropriate and Safe Use.

The use of diagnostic radiography has doubled in the past two decades. Image Gently (children) and Image Wisely (adults) are multidisciplinary initiatives that seek to reduce radiation exposure by eliminating unnecessary procedures and offering best practices. Patients with an estimated glomerular filtration rate less than 30 mL per minute per 1.73 m2 may have increased risk of nephropathy when exposed to iodinated contrast media and increased risk of nephrogenic systemic fibrosis when exposed to gadolinium-based contrast agents. American College of Radiology Appropriateness Criteria can help guide specific diagnostic imaging choices. Noncontrast head computed tomography is the first-line modality when a stroke is suspected. Magnetic resonance imaging stroke protocols and computed tomography perfusion scans can augment evaluation and potentially expand pharmacologic and endovascular therapy timeframes. Imaging should be avoided in patients with uncomplicated headache syndromes unless the history or physical examination reveals red flag features. Cardiac computed tomography angiography, stress echocardiography, and myocardial perfusion scintigraphy (nuclear stress test) are appropriate for patients with chest pain and low to intermediate cardiovascular risk and have comparable sensitivity and specificity. Computed tomography pulmonary angiography is the preferred test for high-risk patients or those with a positive d-dimer test result, and ventilation-perfusion scintigraphy is reserved for patients with an estimated glomerular filtration rate less than 30 mL per minute per 1.73 m2 or a known contrast allergy. Computed tomography with intravenous contrast is preferred for evaluating adults with suspected appendicitis; however, ultrasonography should precede computed tomography in children, and definitive treatment should be initiated if positive. Ultrasonography is the first-line modality for assessing right upper quadrant pain suggestive of biliary disease. Mass size and patient age dictate surveillance recommendations for adnexal masses. Imaging should not be performed for acute (less than six weeks) low back pain unless red flag features are found on patient history. Ultrasonography should be used for the evaluation of suspicious thyroid nodules identified incidentally on computed tomography.

(F)utility of "routine" postprocedural chest radiograph after hemodialysis catheter (central venous catheter) insertion.

A routine postprocedural chest radiograph had been a safe, checklist-based final step of the procedure, since the start of central venous catheter insertion for hemodialysis to check the position of the catheter tip and to rule out complications. However, the chest radiograph is a suboptimal method to rule out complications like pneumothorax and is not a reliable test to confirm its position. Although it is relatively inexpensive, it is labor-intensive and exposes patient to unnecessary radiation exposure, cost, and often results in delayed use of the catheter. Various studies question the value of a routine chest radiograph as a screening test to rule out the mechanical complications of catheter insertion. We, in this brief viewpoint, present evidence to support the futility of a routine postprocedural chest radiograph in majority of asymptomatic patients and support Choosing Wisely Initiative to avoid low-value studies. However, it should be considered under specific indications, as discussed.

Sobrediagnóstico: prejudicando pacientes em nome da saúde / Sobrediagnóstico: daño a las personas en nombre da la salud / Overdiagnosis: harming people in the name of health

À medida que os avanços médico-tecnológicos continuam a se tornar mais facilmente disponíveis, o diagnóstico de pseudo-doenças atingiu o cerne dos sistemas de saúde e tornou-se uma das atividades mais prejudiciais da medicina moderna, tanto individual quanto coletivamente, pois ameaça a sustentabilidade dos sistemas de saúde. Aqui descrevemos um caso hipotético, mas baseado em casos reais, de uma jovem de 36 anos diagnosticada com um carcinoma papilífero de tireoide após ter sido submetida a um check-up excessivo e desnecessário solicitado por um ginecologista em uma consulta de rotina. (AU)

As medical technological advances continue to become more readily available, diagnosis of pseudo-disease has hit the heart of medicine and has become one of the most harmful activities in modern medicine, both individually and collectively speaking as it threatens the sustainability of health systems. Here we describe a hypothetical case (but based on many similar real ones) of a young adult woman in her middle 30's that has been diagnosed with a papillary thyroid cancer after she had been submitted to an excessive and unnecessary check-up elicited by a gynaecologist in a routine medical consultation.

It is feasible to flag 'near end-of-life' status in older patients from routine general practice data.

METHOD: A retrospective chart review was used to assess the feasibility of identifying these indicators in the data (160,897 patients from 464 practices across Australia). Conditional logistic regression was used to assess the independent contribution of nEOL indicators in patients aged 75-84 and ≥85 years using a case-control design matching by practice. RESULTS: The strongest indicators for nEOL status were advanced malignancy, residential aged care, nutritional vulnerability, anaemia, cognitive impairment and heart failure. Other indicators included hospital attendance, pneumonia, decubitus ulcer, chronic obstructive pulmonary disease, antipsychotic prescription, male sex and stroke. DISCUSSION: Consideration of routinely collected patient data may suggest nEOL status and trigger advance care planning discussions.

Does preoperative dipyridamole-thallium scanning reduce 90-day cardiac complications and 1-year mortality in patients with femoral neck fractures undergoing hemiarthroplasty?

BACKGROUND: This study aimed to evaluate the effect of dipyridamole-thallium scanning (DTS) on the rates of 90-day cardiac complications and 1-year mortality in patients with a femoral neck fracture treated with hemiarthroplasty. METHODS: Between 2008 and 2015, 844 consecutive patients who underwent cemented or cementless hemiarthroplasty were identified from the database of a single level-one medical center. One-hundred and thirteen patients (13%) underwent DTS prior to surgery, and 731 patients (87%) did not. Patient characteristics, comorbidities, surgical variables, and length of the delay until surgery were recorded. A propensity score-matched cohort was utilized to reduce recruitment bias in a 1:3 ratio of DTS group to control group, and multivariate logistic regression was performed to control confounding variables. RESULTS: The incidence of 90-day cardiac complications was 19.5% in the DTS group and 15.6% in the control group (p = 0.343) among 452 patients after propensity score-matching. The 1-year mortality rate (10.6% vs 13.3%, p = 0.462) was similar in the two groups. In the propensity score-matched patients, utilization of DTS was not associated with a reduction in the rate of 90-day cardiac complications (matched cohort, adjusted odds ratio [aOR] = 1.32; 95% confidence interval [CI] 0.75-2.33, p = 0.332) or the 1-year mortality rate (aOR = 0.62; 95% CI 0.27-1.42, p = 0.259). Risk factors for cardiac complications included an American Society of Anesthesiologists grade ≥ 3 (OR 3.19, 95% CI 1.44-7.08, p = 0.004) and pre-existing cardiac comorbidities (OR 5.56, 95% CI 3.35-9.25, p < 0.001). Risk factors for 1-year mortality were a long time to surgery (aOR 1.15, 95% CI 1.06-1.25, p = 0.001), a greater age (aOR 1.05, 95% CI 1.00 to 1.10, p = 0.040), a low body mass index (BMI; aOR 0.89, 95% CI 0.81-0.98, p = 0.015), and the presence of renal disease (aOR 4.43, 95% CI 1.71-11.46, p = 0.002). DISCUSSION: Preoperative DTS was not associated with reductions in the rates of 90-day cardiac complications or 1-year mortality in patients with a femoral neck fracture undergoing hemiarthroplasty. The necessity for DTS should be re-evaluated in elderly patients with femoral neck fractures, given that this increases the length of the delay until surgery. LEVEL OF EVIDENCE: Prognostic level III.

Is thyroid excision mandatory with laryngectomy in carcinoma larynx?

BACKGROUND: Advanced stage operable cancers of larynx are treated with total laryngectomy including thyroid resection in most of the cases, which may expose patient to hypothyroidism and hypoparathyroidism. The requirement of thyroidectomy during Total Laryngectomy is controversial. METHODS: A cross sectional observational study was set out to review preoperative clinical and radiological assessment; intraoperative and histopathological findings; and follow-up data to predict thyroid gland invasion in the setting of squamous cell carcinoma of the Larynx. RESULTS: 11 (16%) out of 69 patients had thyroid gland involvement on histopathological examination with mean age 63 years. Out of these 11 cases, 8 (72%) underwent primary total laryngectomy. 90% patients with thyroid gland involvement were male. 9 cases with thyroid gland involvement were staged as T4a preoperatively. CONCLUSION: Invasion of thyroid gland by laryngeal cancer is uncommon. Unnecessary hemithyroidectomies lead to hypothyroidism and hypoparathyroidism. The study points out the clear indications of thyroid excision in patients undergoing total laryngectomy. We can suggest that total thyroidectomy should be done with total laryngectomy in cases which have gross clinical, radiological or intraoperative thyroid gland involvement, subglottic extension and thyroid cartilage invasion. This can save the patients from the brunt of unnecessary morbid hypothyroidism and hypoparathyroidism.

Effect of an Interactive Training on Choosing Delivery Method among Primiparous Pregnant Women: An Interventional Study.

OBJECTIVES: To evaluate the effect of interactive training conducted during pregnancy on choosing delivery method among primiparous women. METHODS: Quasi-experimental study carried out in 2017 in two hospitals in the city of Bushehr (Iran), with the participation of 108 primiparous pregnant women in an educational program consisting of eight 2-hour sessions every two weeks in which interactive training activities were performed (group discussions, classroom sessions, and delivery of printed educational material) on themes related with physiological delivery, painless vaginal delivery methods, and complications of cesarean delivery without indication, among others. Before and after the intervention, the Knowledge and Preferred Method of Delivery Questionnaire by Moradabadi et al., was used to obtain information. RESULTS: The results indicated that the level of knowledge in the group of mothers increased significantly between the pre-intervention and post-intervention assessment (13.2 versus 19.4, of 20 possible maximum points; p < 0.001). Additionally, significant difference was observed in the selection of the vaginal delivery method before and after the intervention (74.1% versus 98.1%; p < 0.001). CONCLUSIONS: Implementation of interactive training increased knowledge of pregnant women on the delivery and induced a positive effect to encourage the primiparous mothers to have a vaginal delivery.

Unindicated hysterectomies in India: the aftermath.

Unindicated hysterectomy is a disturbing problem in India. Women are counselled into the procedure by the fear of cancer, and by reinforcing their notion that unrelated somatic problems are solved by the removal of the uterus. This is a case of a woman from the state of Bihar, India, who was referred to us after an unindicated hysterectomy at the age of 24, performed as a first-line treatment for lower abdominal pain. This highlights the problem of rising hysterectomy in India and the lack of integrated treatment for women with the debilitating condition of chronic pelvic pain. Pelvic pain and vaginal discharge are often not indicative of pelvic inflammatory disease, and need a more considerate and broad-minded approach. Public health initiatives should take more account of women's lack of knowledge of reproductive health and make efforts to disseminate such information by the use of television, radio and newspapers in local languages.

Cascades of Care After Incidental Findings in a US National Survey of Physicians.

Importance: Incidental findings on screening and diagnostic tests are common and may prompt cascades of testing and treatment that are of uncertain value. No study to date has examined physician perceptions and experiences of these cascades nationally. Objective: To estimate the national frequency and consequences of cascades of care after incidental findings using a national survey of US physicians. Design, Setting, and Participants: Population-based survey study using data from a 44-item cross-sectional, online survey among 991 practicing US internists in a research panel representative of American College of Physicians national membership. The survey was emailed to panel members on January 22, 2019, and analysis was performed from March 11 to May 27, 2019. Main Outcomes and Measures: Physician report of prior experiences with cascades, features of their most recently experienced cascade, and perception of potential interventions to limit the negative consequences of cascades. Results: This study achieved a 44.7% response rate (376 completed surveys) and weighted responses to be nationally representative. The mean (SE) age of respondents was 43.4 (0.7) years, and 60.4% of respondents were male. Almost all respondents (99.4%; percentages were weighted) reported experiencing cascades, including cascades with clinically important and intervenable outcomes (90.9%) and cascades with no such outcome (94.4%). Physicians reported cascades caused their patients psychological harm (68.4%), physical harm (15.6%), and financial burden (57.5%) and personally caused the physicians wasted time and effort (69.1%), frustration (52.5%), and anxiety (45.4%). When asked about their most recent cascade, 33.7% of 371 respondents reported the test revealing the incidental finding may not have been clinically appropriate. During this most recent cascade, physicians reported that guidelines for follow-up testing were not followed (8.1%) or did not exist to their knowledge (53.2%). To lessen the negative consequences of cascades, 62.8% of 376 respondents chose accessible guidelines and 44.6% chose decision aids as potential solutions. Conclusions and Relevance: The survey findings indicate that almost all respondents had experienced cascades after incidental findings that did not lead to clinically meaningful outcomes yet caused harm to patients and themselves. Policy makers and health care leaders should address cascades after incidental findings as part of efforts to improve health care value and reduce physician burnout.

Predicting Biopsy Outcomes During Active Surveillance for Prostate Cancer: External Validation of the Canary Prostate Active Surveillance Study Risk Calculators in Five Large Active Surveillance Cohorts.

BACKGROUND: Men with prostate cancer (PCa) on active surveillance (AS) are followed through regular prostate biopsies, a burdensome and often unnecessary intervention, not without risks. Identifying men with at a low risk of disease reclassification may help reduce the number of biopsies. OBJECTIVE: To assess the external validity of two Canary Prostate Active Surveillance Study Risk Calculators (PASS-RCs), which estimate the probability of reclassification (Gleason grade ≥7 with or without >34% of biopsy cores positive for PCa) on a surveillance biopsy, using a mix of months since last biopsy, age, body mass index, prostate-specific antigen, prostate volume, number of prior negative biopsies, and percentage (or ratio) of positive cores on last biopsy. DESIGN, SETTING, AND PARTICIPANTS: We used data up to November 2017 from the Movember Foundation's Global Action Plan (GAP3) consortium, a global collaboration between AS studies. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: External validity of the PASS-RCs for estimating reclassification on biopsy was assessed by calibration, discrimination, and decision curve analyses. RESULTS AND LIMITATIONS: Five validation cohorts (Prostate Cancer Research International: Active Surveillance, Johns Hopkins, Toronto, Memorial Sloan Kettering Cancer Center, and University of California San Francisco), comprising 5105 men on AS, were eligible for analysis. The individual cohorts comprised 429-2416 men, with a median follow-up between 36 and 84 mo, in both community and academic practices mainly from western countries. Abilities of the PASS-RCs to discriminate between men with and without reclassification on biopsy were reasonably good (area under the receiver operating characteristic curve values 0.68 and 0.65). The PASS-RCs were moderately well calibrated, and had a greater net benefit than most default strategies between a predicted 10% and 30% risk of reclassification. CONCLUSIONS: Both PASS-RCs improved the balance between detecting reclassification and performing surveillance biopsies by reducing unnecessary biopsies. Recalibration to the local setting will increase their clinical usefulness and is therefore required before implementation. PATIENT SUMMARY: Unnecessary prostate biopsies while on active surveillance (AS) should be avoided as much as possible. The ability of two calculators to selectively identify men at risk of progression was tested in a large cohort of men with low-risk prostate cancer on AS. The calculators were able to prevent unnecessary biopsies in some men. Usefulness of the calculators can be increased by adjusting them to the characteristics of the population of the clinic in which the calculators will be used.

Fast and slow thinking; and the problem of conflating clinical reasoning and ethical deliberation in acute decision-making.

Expertise in a medical specialty requires countless hours of learning and practice and a combination of neural plasticity and contextual case experience resulting in advanced gestalt clinical reasoning. This holistic thinking assimilates complex segmented information and is advantageous for timely clinical decision-making in the emergency department and paediatric or neonatal intensive care units. However, the same agile reasoning that is essential acutely may be at odds with the slow deliberative thought required for ethical reasoning and weighing the probability of patient morbidity. Recent studies suggest that inadequate ethical decision-making results in increased morbidity for patients and that clinical ethics consultation may reduce the inappropriate use of life-sustaining treatment. Behavioural psychology research suggests there are two systems of thinking - fast and slow - that control our thoughts and therefore our actions. The problem for experienced clinicians is that fast thinking, which is instinctual and reflexive, is particularly vulnerable to experiential biases or assumptions. While it has significant utility for clinical reasoning when timely life and death decisions are crucial, I contend it may simultaneously undermine the deliberative slow thought required for ethical reasoning to determine appropriate therapeutic interventions that reduce future patient morbidity. Whilst health-care providers generally make excellent therapeutic choices leading to good outcomes, a type of substitutive thinking that conflates clinical reasoning and ethical deliberation in acute decision-making may impinge on therapeutic relationships, have adverse effects on patient outcomes and inflict lifelong burdens on some children and their families.

Did Bioethics Matter? A History of Autonomy, Consent, and Intersex Genital Surgery.

This article argues that the rise of bioethics in the post-WWII era and the emergence of the legal doctrine of informed consent in the late 1950s should have had a greater impact on patients with intersex traits (atypical sex development) than they did, given their emphasis on respect for autonomy and beneficence toward patients. Instead, these progressive trends collided with a turn in intersex management toward infants, who were unable to provide autonomous consent about their medical care. Patient autonomy took a back seat as parents heeded physicians' advice in an environment even more hierarchical than we know today. Intersex care of both infants and adults continues to need improvement. It remains an open question whether the abstract ideals of bioethics-respect, patient autonomy, and the requirement of informed consent-are alone adequate to secure that improvement, or whether legal actions (or the threat of litigation) or some other reforms will be required to effect such change.

The Unacceptable Morbidity of Negative Laparoscopic Appendicectomy.

BACKGROUND: One of the most common acute conditions managed by general surgeons is acute appendicitis. Laparoscopic appendicectomy (LA) is the surgical technique used by many surgeons. The aims of this study were to define our unit's negative appendicectomy rate and compare the outcomes associated with removal of a normal appendix with those for acute appendicitis in patients having LA. METHODS: A single-centre retrospective case note review of patients undergoing LA for suspected acute appendicitis was performed. Patients were divided into positive and negative appendicectomy groups based on histology results. The positive group was subdivided into uncomplicated and complicated (perforated and/or gangrenous) appendicitis. Outcomes were compared between groups. RESULTS: There were 1413 patients who met inclusion criteria, 904 in the positive group and 509 in the negative group, an overall negative appendicectomy rate of 36.0%. Morbidity rates (6.3% vs. 6.9%; P = 0.48) and types of morbidity were the same for negative appendicectomy and uncomplicated appendicitis. There was no significant difference in complication severity (all P > 0.17) or length of stay (2.3 vs. 2.6 days; P = 0.06) between negative appendicectomy and uncomplicated appendicitis groups. Patients with complicated appendicitis had a significantly higher morbidity rate compared to negative and uncomplicated groups (20.1% vs. 6.3% and 20.1% vs. 6.9%; both P < 0.001). CONCLUSION: The morbidity of negative LA is the same as LA for uncomplicated appendicitis. The morbidity of LA for complicated appendicitis is significantly higher. The selection criteria for LA in our unit needs to be reviewed to address the high negative appendicectomy rate and avoid unnecessary surgery and its associated morbidity.

Interventions targeted at health professionals to reduce unnecessary caesarean sections: a qualitative evidence synthesis.

OBJECTIVE: To establish the views and experiences of healthcare professionals in relation to interventions targeted at them to reduce unnecessary caesareans. DESIGN: Qualitative evidence synthesis. SETTING: Studies undertaken in high-income, middle-income and low-income settings. DATA SOURCES: Seven databases (CINAHL, MEDLINE, PsychINFO, Embase, Global Index Medicus, POPLINE and African Journals Online). Studies published between 1985 and June 2017, with no language or geographical restrictions. We hand-searched reference lists and key citations using Google Scholar. STUDY SELECTION: Qualitative or mixed-method studies reporting health professionals' views. DATA EXTRACTION AND SYNTHESIS: Two authors independently assessed study quality prior to extraction of primary data and authors' interpretations. The data were compared and contrasted, then grouped into summary of findings (SoFs) statements, themes and a line of argument synthesis. All SoFs were Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) assessed. RESULTS: 17 papers were included, involving 483 health professionals from 17 countries (nine high-income, six middle-income and two low-income). Fourteen SoFs were identified, resulting in three core themes: philosophy of birth (four SoFs); (2) social and cultural context (five SoFs); and (3) negotiation within system (five SoFs). The resulting line of argument suggests three key mechanisms of effect for change or resistance to change: prior beliefs about birth; willingness or not to engage with change, especially where this entailed potential loss of income or status (including medicolegal barriers); and capacity or not to influence local community and healthcare service norms and values relating to caesarean provision. CONCLUSION: For maternity care health professionals, there is a synergistic relationship between their underpinning philosophy of birth, the social and cultural context they are working within and the extent to which they were prepared to negotiate within health system resources to reduce caesarean rates. These findings identify potential mechanisms of effect that could improve the design and efficacy of change programmes to reduce unnecessary caesareans. PROSPERO REGISTRATION NUMBER: CRD42017059455.

Non-clinical interventions to reduce unnecessary caesarean section targeted at organisations, facilities and systems: Systematic review of qualitative studies.

OBJECTIVE: When medically indicated, caesarean section can prevent deaths and other serious complications in mothers and babies. Lack of access to caesarean section may result in increased maternal and perinatal mortality and morbidity. However, rising caesarean section rates globally suggest overuse in healthy women and babies, with consequent iatrogenic damage for women and babies, and adverse impacts on the sustainability of maternity care provision. To date, interventions to ensure that caesarean section is appropriately used have not reversed the upward trend in rates. Qualitative evidence has the potential to explain why and how interventions may or may not work in specific contexts. We aimed to establish stakeholders' views on the barriers and facilitators to non-clinical interventions targeted at organizations, facilities and systems, to reduce unnecessary caesarean section. METHODS: We undertook a systematic qualitative evidence synthesis using a five-stage modified, meta-ethnography approach. We searched MEDLINE, CINAHL, PsychINFO, EMBASE and grey literature databases (Global Index Medicus, POPLINE, AJOL) using pre-defined terms. Inclusion criteria were qualitative and mixed-method studies, investigating any non-clinical intervention to reduce caesarean section, in any setting and language, published after 1984. Study quality was assessed prior to data extraction. Interpretive thematic synthesis was undertaken using a barriers and facilitators lens. Confidence in the resulting Summaries of Findings was assessed using GRADE-CERQual. RESULTS: 8,219 studies were identified. 25 studies were included, from 17 countries, published between 1993-2016, encompassing the views of over 1,565 stakeholders. Nineteen Summary of Findings statements were derived. They mapped onto three distinct themes: Health system, organizational and structural factors (6 SoFs); Human and cultural factors (7 SoFs); and Mechanisms of effect to achieve change factors (6 SoFs). The synthesis showed how inter- and intra-system power differentials, and stakeholder commitment, exert strong mechanisms of effect on caesarean section rates, independent of the theoretical efficacy of specific interventions to reduce them. CONCLUSIONS: Non-clinical interventions to reduce caesarean section are strongly mediated by organisational power differentials and stakeholder commitment. Barriers may be greatest where implementation plans contradict system and cultural norms. PROTOCOL REGISTRATION: PROSPERO: CRD42017059456.

Human Penile Transplantation: An Unjustified Ethical Dilemma?

Vascularized composite allotransplantation has enabled the performance of five reported penile transplantations across the world with additional transplantations planned. Penile transplantation raises ethical questions concerning aesthetics, morbidity, function, and cost-burden given the more readily available and less morbid alternative of phalloplasty.
