Perceptions of artificial intelligence in healthcare: findings from a qualitative survey study among actors in France.

BACKGROUND: Artificial intelligence (AI), with its seemingly limitless power, holds the promise to truly revolutionize patient healthcare. However, the discourse carried out in public does not always correlate with the actual impact. Thus, we aimed to obtain both an overview of how French health professionals perceive the arrival of AI in daily practice and the perception of the other actors involved in AI to have an overall understanding of this issue. METHODS: Forty French stakeholders with diverse backgrounds were interviewed in Paris between October 2017 and June 2018 and their contributions analyzed using the grounded theory method (GTM). RESULTS: The interviews showed that the various actors involved all see AI as a myth to be debunked. However, their views differed. French healthcare professionals, who are strategically placed in the adoption of AI tools, were focused on providing the best and safest care for their patients. Contrary to popular belief, they are not always seeing the use of these tools in their practice. For healthcare industrial partners, AI is a true breakthrough but legal difficulties to access individual health data could hamper its development. Institutional players are aware that they will have to play a significant role concerning the regulation of the use of these tools. From an external point of view, individuals without a conflict of interest have significant concerns about the sustainability of the balance between health, social justice, and freedom. Health researchers specialized in AI have a more pragmatic point of view and hope for a better transition from research to practice. CONCLUSION: Although some hyperbole has taken over the discourse on AI in healthcare, diverse opinions and points of view have emerged among French stakeholders. The development of AI tools in healthcare will be satisfactory for everyone only by initiating a collaborative effort between all those involved. It is thus time to also consider the opinion of patients and, together, address the remaining questions, such as that of responsibility.

[The myth of virgin cleansing: Latest news on an archaic magico-religious practice]. / Le mythe du nettoyage par les vierges : actualité d'un archaïsme magico-religieux.

BACKGROUND: In the medical anthropology section of the Nanterre Hospital (France) for migrants and refugees, three cases were recorded of "virgin cleansing" in sub-Saharan African countries. PATIENTS AND METHODS: These consisted of sexual assaults (2 instances of rape and 1 of sexual interference) on sexually immature females (young girls) by patients with sexually transmitted infections (mainly HIV, syphilis) hoping they might thereby be cured. DISCUSSION: These particularly atrocious hetero-aggressive sexual practices based on magical arguments are unfortunately universal and are not limited to a specific culture. At the medical anthropology level, the belief in cleansing by virgins is based on the notion that the patient is dirty and impure. In the same way that emetics and/or laxatives are prescribed in the case of intestinal disorders (to "eliminate" the disease), some subjects use diuretics for urinary abnormalities or, literally, "clean vaginas (or anuses)" to purge their own miasma. The rising tide of population migrations (some of whom carry chronic infections), refugee camps, prolonged incarcerations, etc., makes observations of such phenomena increasingly frequent. Belief in cleansing by virgins (and the fatal consequences thereof) will be difficult to eradicate. The education of populations and health professionals should promote absolute respect for the body of children, and, more generally, of others, particularly since at this time of increasingly marked migratory flows, this problem sadly risks becoming widespread.

Mycobacterium avium complex disseminated infection in a kidney transplant recipient.

Mycobacterium avium-intracellulare complex (MAC) infections are well known in immunocompromised patients, notably in human immunodeficiency virus infection, but remain scarcely described in kidney transplantation. Moreover, cutaneous involvement in this infection is very unusual. We describe here a disseminated infection caused by MAC in a kidney transplant recipient revealed by cutaneous lesions. This case highlights the need for an exhaustive, iterative microbiologic workup in the context of an atypical disease presentation in a renal transplant patient, regardless of the degree of immunosuppression.

How nonverbal communication shapes the doctor-patient relationship: from paternalism to the ethics of care in oncology.

The purpose of this research, led in the wake of years of pressure to reject paternalism, was to study whether controlled practice of nonverbal communication by doctors inheres a continued risk of paternalistic attitudes in oncology clinic interviews (chosen to illustrate the doctor-patient relationship). This study involved qualitative descriptive research based on interview observations and questionnaires and mobilized recognized theory borrowed from sociology and anthropology. We found that the legislative framework governing the doctor-patient relationship has simply shifted the paternalism issue from verbal communication over to a new area that doctors have not yet mastered and patients have not yet understood, i.e., nonverbal communication. This study shows that all the laws framing the doctor-patient relationship can be circumvented, and that by controlling nonverbal communication, the doctor can fall back into paternalism. The rejection of paternalism therefore needs to lead to an appropriate reading of the patient's story, which in ethical terms can only happen if hospital structures are made non-paternalizing by design, if doctors learn to understand the patient's different chronemic timeframe, and if doctors committedly engage in the Hippocratic Oath codified through the ethics of care.

Validating a blood donation awareness tool created using general practitioner and patient acceptability and preferences.

BACKGROUND: There is a need to develop an awareness raising tool for GPs to reach out their patients in order to increase blood donation. The main objective was to create and validate a tool to raise awareness about blood donation that meets acceptability and preference criteria and is applicable in general practice. MATERIAL AND METHODS: This cross-sectional study was conducted in three phases. 1. Tool creation: A stakeholder meeting co-developed three potential tools to raise awareness about blood donation: a consulting room poster, a waiting room poster and a lapel badge for the doctor. Three GPs pilot-tested each tool for one day during their regular consultations. Then, once the pilot was completed each GP assessed acceptability and preference using a semi-structured interview, and patients were also interviewed. 2. Consensual tool selection: An appropriate tool was selected based on pilot data using nominal group technique and expert review. 3. The tool was validated for its acceptability in practice via a quantitative questionnaire distributed electronically to GPs. RESULTS: The consensual tool selected by the nominal group was a combination of elements from all three tools trialled in the pilot, reported to be non-intrusive and convenient for both GPs and patients. Patient responses indicated a high level of acceptability and indicated a strong preference for self-generated discussion of the topic with their GP. In the validation step, 217 responses to the quantitative questionnaire were received: 74.5% of responses fulfilled the acceptability criteria for using this combined tool in general practice. Furthermore, 93.1% of GPs indicated they would use the tool in the proposed format for the purpose of raising awareness. DISCUSSION: The validation of our blood donation awareness tool for use in general practice justifies its evaluation on a larger scale as part of a wider blood donation awareness campaign.

Incidence, risk factors and clinical consequences of neutropenia following kidney transplantation: a retrospective study.

Neutropenic episodes in kidney transplant patients are poorly characterized. In this retrospective study, neutropenia was experienced by 112/395 patients (28%) during the first year posttransplant. The only factor found to be significantly associated with the occurrence of neutropenia was combined tacrolimus-mycophenolate therapy (p < 0.001). Neutropenic patients experienced more bacterial infections (43% vs. 32%, p = 0.04). Grade of neutropenia correlated with the global risk of infection. Discontinuation of mycophenolic acid (MPA) due to neutropenia was associated with an increased incidence of acute rejection (odds ratios per day 1.11, 95% confidence intervals 1.02-1.22) but not with reduced renal function at 1 year. The time from onset of neutropenia to MPA discontinuation correlated with the duration of neutropenia. Granulocyte colony-stimulating factor (G-CSF) administration was safe and effective in severely neutropenic kidney graft recipients, with absolute neutrophil count >1000/microL achieved in a mean of 1.5+/-0.5 days. Neutropenia is an important and frequent laboratory finding that may exert a significant influence on outcomes in kidney transplantation. As well as leading to an increased incidence of infection, it is associated with a higher rate of allograft rejection if MPA is discontinued for >6 days (p = 0.02). G-CSF accelerates recovery of neutropenia and may be a good therapeutic alternative for severely neutropenic patients.

[Place of nephrectomy in patients with autosomal dominant polycystic kidney disease waiting for renal transplantation]. / Place de la néphrectomie chez les patients atteints de polykystose rénale autosomique dominante de l'adulte en attente de transplantation rénale.

OBJECTIVE: To define the indications, results and place of nephrectomy for autosomal dominant polycystic kidney disease (ADPKD) in relation to renal transplantation. MATERIAL AND METHODS: Between October 1998 and February 2006, 145 patients with ADPKD were followed in our institution; 38 of them underwent nephrectomy via a subcostal incision, mainly in preparation for renal transplantation. The decision to perform nephrectomy in preparation for renal transplantation was based on clinical examination and CT findings. RESULTS: Indications for nephrectomy were preparation for renal transplantation (n=28, 68%), severe urological complications (n=12) and malignant tumour (n=1). Forty-one nephrectomies were performed, pretransplantation in 36 cases (88%) and five post-transplantation nephrectomies in three patients. The nephrectomy rate was 26%. The median kidney weight was 2800 grams. The mean operating time was 100 minutes and mean blood loss was 76 ml. The overall morbidity was 36.6% with 7.3% of serious complications. The mean hospital stay was 14.5 days. No patient nephrectomized before transplantation (n=13) developed any complications of the contralateral native kidney with a mean follow-up of 33 months. The mean interval between initiation of dialysis and transplantation and between nephrectomy and transplantation was 30 and 16 months, respectively. CONCLUSIONS: The optimal timing and incision for nephrectomy for ADPKD are still a subject of debate. In the absence of urological complications, nephrectomy, associated with considerable morbidity, should only be performed when very large kidneys truly interfere with graft implantation. Systematic unilateral or bilateral nephrectomy must therefore no longer be proposed. To avoid the complications of the anephric state, it is preferable to wait, whenever possible, until the patient is placed on dialysis, but the development of pre-emptive transplantation raises the issue of concomitant nephrectomy and transplantation, which may be a feasible option.

[Not-for-profit: A report from the fourth annual symposium of ethics held by the National Institute for Blood Transfusion (France)]. / À propos du non-profit : rapport du quatrième symposium annuel d'éthique transfusionnelle de l'Institut national de la transfusion sanguine.

The not-for-profit issue has been debated in November 2016 in Paris; this issue is one of the four canonical pillars of ethical blood donation. It is intimately bound to benevolence though it is distinct, as not-for-profit calls for institutions while benevolence calls for individuals. It is indeed intended that voluntary blood donors do not benefit from their donation and are thus non-remunerated. Not-for-profit is essential since it refers to the public character of blood as a putative public resource aimed at being shared as a tribute of solidarity. A central question however is linked to the capacity- or not -of public sectors to ensure that blood components are universally available, with special mention to plasma derived drugs, without the contribution of the for profit, private sector.

Hepatitis C virus-related fibrosing cholestatic hepatitis after renal transplantation.

Fibrosing cholestatic hepatitis is a well-described syndrome in patients with immunodeficiency and chronic hepatitis B. It is clinically, biologically, and histologically characterized by rapidly progressive hepatic failure, a mildly elevated serum aminotransferase level, an extensive periportal fibrosis associated with intense cholestasis, mild inflammatory cellular infiltrate, no cirrhosis, and a high hepatocellular level expression of B viral antigens. This syndrome reflected a direct hepatocytopathic injury linked to high intrahepatic viral antigen expression. Because the syndrome of fibrosing cholestatic hepatitis has not been described in chronic hepatitis C, we report the first well-characterized case in a renal transplant patient with chronic hepatitis C and discuss the clinical and pathogenic implications of such a syndrome in this setting.

Kidney transplantation at Necker Hospital: the most recent 5-year period (2004-2009).

The results of our last 5 years activity in kidney transplantation clearly show that it is possible to perform high-risk transplantations with very acceptable results: ECD kidneys, dual transplantation, recipients with DSAs. In depth statistical analysis of these data should allow a clearer definition of the best strategies to use in these situations.

Arterial and mixed venous acid-base status in patients with cirrhosis. Influence of liver failure.

Although it has been established that liver failure is associated with arterial hypocapnia and alkalaemia (i.e., respiratory alkalosis), the influence of liver failure on mixed venous acid-base status has not yet been studied. Thus, arterial and mixed venous acid-base status were simultaneously measured in controls and in a large series of patients with cirrhosis. Grade B patients (n = 28) or Grade C patients (n = 21) had significantly lower arterial and mixed venous carbon dioxide tensions than controls (n = 29). Grade B or Grade C patients also had significantly higher arterial, mixed venous pH, and lower mixed venous bicarbonate concentrations than controls. Among Grade A patients (n = 27), those with the lowest Pugh's score (i.e., equal to five) had significantly lower mixed venous carbon dioxide tension than controls. The other arterial and mixed venous acid-base values did not differ significantly between Grade A patients with the lowest Pugh's score and controls. Grade A patients with a Pugh's score equal to six and Grade B patients had similar acid-base disorders. No significant differences were found between groups concerning the anion gap and plasma chloride concentrations. In conclusion, this study shows that in Grade B or C patients, respiratory alkalosis was responsible for mixed venous hypocapnia, alkalaemia and hypobicarbonataemia. In addition, in Grade A patients with the lowest Pugh's score (equal to five), analysis of arterial and mixed venous blood revealed that mixed venous hypocapnia was the sole anomaly of the acid-base status. This last finding suggests that mixed venous hypocapnia might be an early event preceding the onset of arterial hypocapnia.

Septic shock in patients with cirrhosis: hemodynamic and metabolic characteristics and intensive care unit outcome.

OBJECTIVES: To examine the hemodynamic and metabolic characteristics and ICU outcome of septic shock in patients with cirrhosis. DESIGN: Prospective, comparative study. Measurements performed in the first 24 hrs of septic shock. SETTING: A general hospital ICU. PATIENTS: Twelve patients with cirrhosis and 23 patients without cirrhosis admitted for septic shock. MEASUREMENTS AND MAIN RESULTS: Arterial pressure was measured using an arterial catheter. Pulmonary arterial and right atrial pressures were measured by using a pulmonary artery catheter. Cardiac output was determined by using the thermodilution method. Pulmonary arterial L-lactate plasma concentrations were measured using an automated spectrophotometer, and blood temperature was measured using a cardiac output computer. Arterial and mixed venous PO2, PCO2, and pH values were measured by using specific electrodes. Oxygen saturations and hemoglobin concentrations were measured using a hemoximeter. Patients with cirrhosis had decompensated liver disease (grade C of the Child-Pugh classification). The number of Gram-negative infections and therapeutic interventions were similar in both groups. Patients with cirrhosis had higher cardiac indices (5.14 +/- 0.52 [SE] vs. 3.91 +/- 0.30 L/min/m2, p less than .05), plasma lactate concentrations (9.0 +/- 2.0 vs. 5.2 +/- 0.7 mmol/L, p less than .05) and ICU mortality rates (100% vs. 43%, p less than .05), and lower blood temperatures (35.5 +/- 0.6 vs. 37.6 +/- 0.2 degrees C, p less than .05) than patients without cirrhosis. Systemic vascular resistance, arterial pressure, pulmonary arterial pressure, oxygen delivery and consumption, and arterial and mixed venous acid-base status were not significantly different between the two groups. CONCLUSIONS: In patients with cirrhosis, septic shock was characterized by severe liver dysfunction, low blood temperature, marked increases in cardiac index and lactic acidemia, and a 100% ICU mortality rate. These findings should be taken into account if patients with cirrhosis are to be included in controlled studies on septic shock.

Use of tunneled femoral catheters to prevent catheter-related infection. A randomized, controlled trial.

BACKGROUND: The risk for catheter-related infection seems higher with femoral catheters than with catheters inserted at other sites. OBJECTIVE: To evaluate the effect of catheter tunneling on femoral catheter-related infection in critically ill patients. DESIGN: Randomized, controlled trial. SETTING: Three intensive care units at academic hospitals in Paris, France. PATIENTS: 345 adult patients requiring a femoral venous catheter for more than 48 hours. INTERVENTION: Tunneled or nontunneled femoral catheters. MEASUREMENTS: Time to occurrence of systemic catheter-related sepsis, catheter-related bloodstream infection, and quantitative catheter tip culture with a cutoff of 10(3) colony-forming units/mL. RESULTS: Of 345 randomly assigned patients, 336 were evaluable. Probable systemic catheter-related sepsis occurred in 15 of 168 patients who received a nontunneled femoral catheter (controls) and in 5 of 168 patients who received a tunneled femoral catheter (estimated absolute risk reduction, 6% [95% CI, 0.9% to 11%]). Time to occurrence of catheter-related bloodstream infection was not significantly modified (relative risk, 0.28 [CI, 0.03 to 1.92]; P = 0.18); 3 events occurred in the control group and 1 event occurred in the tunneled-catheter group. After stratification by treatment center and adjustment for variables that were prognostic (use of broad-spectrum antimicrobial agents at catheter insertion) or imbalanced between both groups (mechanical ventilation at insertion), tunnelized catheterization reduced the proportion of patients who developed systemic catheter-related sepsis (relative risk, 0.25 [CI, 0.09 to 0.72]; P = 0.005) and positive quantitative culture of the catheter tip (relative risk, 0.48 [CI, 0.23 to 0.99]; P = 0.045). CONCLUSION: The incidence of femoral catheter-related infections in critically ill patients can be reduced by using subcutaneous tunneling.
