Infections nosocomiales en médecine ambulatoire: importance et prévention [Importance and prevention of nosocomial infections in the outpatient setting]

The concept of nosocomial infections (or healthcare-related infections) applies to the outpatients clinics. However, data are scarce and imprecise in this setting compared with hospitals. The choice of preventive measures is therefore difficult. A lower risk in the outpatient facilities does not justify the complete implementation of hospital precautions. The latter can nevertheless be adapted since infection may be acquired during an ambulatory consultation through the same mechanisms as in hospitals. We propose a preventive strategy derived from standard precautions to be applied in every case, transmission-based precautions that are more rarely needed, and asepsis in case of invasive procedure.

Androgen dependence of hirsutism, acne, and alopecia in women : retrospective analysis or 228 patients investigated for hyperandrogenism

RAPPORT DE SYNTHESE : L'hirsutisme, l'acné et l'alopécie chez la femme sont souvent associés à des troubles menstruels et à une production excessive d'androgènes, raison pour laquelle ces symptômes cutanés font l'objet d'évaluation endocrinienne. L'hyperandrogénie affecte 5 à 10 % des femmes en âge de reproduction et constitue un motif fréquent de consultation. Récemment, les sociétés d'endocrinologie ont émis des recommandations sur l'investigation et le traitement de l'hyperandrogénie. Longtemps confrontés à la demande de patientes souffrant d'hirsutisme, d'acné ou d'alopécie, nous avons décidé d'effectuer une approche diagnostique et thérapeutique comportant des dosages hormonaux et un traitement antiandrogénique. Un grand nombre de patientes a été ainsi étudié au fil des années. Les paramètres mesurés incluaient la testostérone plasmatique totale, l'androstènedione, le sulfate de déhydroépiandrostérone (DHEAS), la sex hormone-binding globulin (SHBG) et la testostérone salivaire. Cette dernière est considérée comme un bon reflet de la testostérone libre plasmatique, indépendamment des protéines de liaison. L'analyse rétrospective des dossiers nous a permis de comparer nos données avec celles de la littérature. Des 318 dossiers de patientes ayant consulté notre Service pour hirsutisme, acné ou alopécie pendant 6 ans, 228 ont pu être retenus pour une évaluation adéquate. Chez les patientes présentant ces symptômes de façon isolée, les taux d'androgènes et la prévalence de l'oligo-aménorhée étaient plus élevés en cas d'hirsutisme qu'en cas d'alopécie, avec des valeurs intermédiaires en cas d'acné. Aucun des androgènes mesurés ne permettait, à lui seul, d'identifier tous les cas d'hyperandrogénie, mais la testostérone salivaire a montré la meilleure corrélation positive avec l'hirsutisme, alors que la testostérone plasmatique totale montrait la moins bonne corrélation, et l'androstènedione, le DHEAS et la SHBG des corrélations intermédiaires (corrélation négative pour la SHBG). De plus, au cours du traitement antiandrogénique, la testostérone salivaire a montré l'abaissement proportionnel le plus marqué de tous les androgénes mesurés. Comparées aux patientes originaires d'Europe centrale, les patientes originaires d'Europe du sud consultaient avec des degrés d'hirsutisme supérieurs, mais aucune différence n'a été observée dans les corrélations entre l'hirsutisme et les taux hormonaux de ces deux groupes. En l'absence d'un nombre suffisant d'échographies ovariennes, .la prévalence du syndrome des ovaires polykystiques a été probablement sous-estimée (63 patientes, 27.6 % des cas), au bénéfice du diagnostic d'hyperandrogénie avec euménorrhée (101, 44.3 %); les autres diagnostics étaient: androgénes normaux (51, 22.4%), SHBG basse isolée (7, 3.1%), hyperplasie surrénalienne congénitale non-classique (4, 1.8%), et tumeur ovarienne (2, 0.9%). Nous avons comparé les divers traitements médicaux de l'hirsutisme publiés au cours des 25 dernières années, quant à leur efficacité et leur coût. La sensibilisation à l'insuline avec metformin est moins efficace, mais aussi moins chère. L'anti-androgène flutamide et l'inhibiteur de la 5-α reductase finastéride figurent parmi les traitements les plus performants, mais ils sont aussi les plus chers. Le traitement anti-androgénique et de suppression hormonale avec acétate de cyprotérone et éthinyloestradiol, utilisé dans cette étude, est également parmi les plus efficaces, tout en étant nettement moins cher. Cette étude est la première comparant directement les taux d'androgènes et la prévalence de l'oligoaménorrhée dans les 3 symptômes cutanés d'hyperandrogénie, hirsutisme, acné et alopécie, et elle démontre leur différente dépendance aux androgènes. La salive apparait comme un milieu de choix pour identifier ces patientes et la recommandation actuelle de doser la testostérone plasmatique totale en premier, pour distinguer l'hyperandrogénie de l'hirsutisme idiopathique, nous paraît inadéquate. Nous proposons, au contraire, d'abandonner ce dosage au profit de celui de la testostérone salivaire. Par ailleurs, notre étude infirme l'hypothèse d'une sensibilité cutanée accrue aux androgènes chez les femmes originaires du sud de l'Europe. Finalement, elle est la seule à comparer les effets cliniques, les changements biologiques et le coût annuel des traitements publiés de l'hirsutisme.

Improved earthquake response via simulation and integrated space- and ground-based technologies: the TREMOR proposal

Earthquakes occurring around the world each year cause thousands ofdeaths, millions of dollars in damage to infrastructure, and incalculablehuman suffering. In recent years, satellite technology has been asignificant boon to response efforts following an earthquake and itsafter-effects by providing mobile communications between response teamsand remote sensing of damaged areas to disaster management organizations.In 2007, an international team of students and professionals assembledduring theInternational Space University’s Summer Session Program in Beijing, Chinato examine how satellite and ground-based technology could be betterintegrated to provide an optimised response in the event of an earthquake.The resulting Technology Resources for Earthquake MOnitoring and Response(TREMOR) proposal describes an integrative prototype response system thatwill implement mobile satellite communication hubs providing telephone anddata links between response teams, onsite telemedicine consultation foremergency first-responders, and satellite navigation systems that willlocate and track emergency vehicles and guide search-and-rescue crews. Aprototype earthquake simulation system is also proposed, integratinghistorical data, earthquake precursor data, and local geomatics andinfrastructure information to predict the damage that could occur in theevent of an earthquake. The backbone of these proposals is a comprehensiveeducation and training program to help individuals, communities andgovernments prepare in advance. The TREMOR team recommends thecoordination of these efforts through a centralised, non-governmentalorganization.

L'intégration de la sexualité en consultation gynécologique : discordances entre les perceptions des femmes et celles des gynécologues.

Dès les années 2000, l'Office Fédéral de la Santé Publique recommande aux médecins de premier recours, dont les gynécologues, d'aborder activement la sexualité en consultation, en raison notamment de l'augmentation des infections sexuellement transmissibles asymptomatiques (1ST). Dans le même sens, comme le montrent nombre d'études, plus de 70% des patientes souhaiteraient être interrogées au sujet de leur sexualité en consultation gynécologique. Or, il semble que peu de médecins intègrent systématiquement des questions de sexualité dans leur anamnèse. La revue de la littérature relève que les recherches réalisées à ce jour ont été menées principalement à l'aide de questionnaire selon une perspective naturaliste, qui étudie la sexualité de manière décontextualisée et qui la conçoit comme un invariant biologique et par conséquent universel. Notre objectif est de saisir en profondeur les perceptions et le vécu des gynécologues et des femmes, face à l'intégration de la sexualité en consultation gynécologique. Nous avons adopté une perspective critique en psychologie de la santé (Santiago-Delefosse & Chamberlain, 2008 ; Murray, 2004a ; Lyons & Chamberlain, 2006) qui permet de privilégier d'une part, l'étude de la signification que les sujets donnent à la sexualité dans leur contexte socio-historique et, d'autre part, une vision de l'être humain comprenant des dimensions corporelles, psychologiques et sociétales (Santiago-Delefosse, 2011). Pour ce faire, nous avons utilisé un dispositif de méthodes mixtes en deux phases. Dans la première phase, nous avons mené 21 entretiens semi directifs avec des gynécologues hommes et femmes. Puis, nous avons réalisé 3 groupes focalisés (N=16) avec des femmes âgées de 23 à 65 ans. La seconde phase a consisté à créer un questionnaire, élaboré à partir des résultats de la première phase, afin d'élargir l'expérience de l'intégration de la sexualité en consultation, à une population plus diversifiée de femmes (N=421). Les données récoltées par le biais de ces trois méthodes nous ont permis d'esquisser un modèle présentant les processus en jeu dans la situation de non intégration de la sexualité en consultation gynécologique. Celui-ci relève non seulement des lacunes dans le cursus universitaire de médecine en matière de sexualité, mais également d'importantes discordances entre les gynécologues et les femmes interviewés concernant le rôle du gynécologue, la perception de l'intime, la perception d'introduire le sujet de la sexualité en consultation, ainsi que de la définition même de la sexualité. Nos résultats ouvrent sur des perspectives pratiques pour la consultation gynécologique, ainsi que sur des pistes pour des recherches futures dans l'étude de la sexualité, selon une perspective plus intégrative. -- Since the 2000's, the Swiss Federal Office of Public Health recommended primary care physicians, including gynaecologists, to actively address sexuality issues in consultation, namely because of the increasing incidence of Sexually Transmitted Infections (STI). In line with this, studies have shown that more than 70% of patients would like to be asked about their sexuality by their gynaecologist. However, physicians do not take systematically sexual histories from their patients. Literature in the field has highlighted that most research has been restricted to using questionnaires following a naturalist theoretical perspective according to which sexual behaviour is defined as biologically invariant, hence, universal. Our objective is to deepen understand perceptions from gynaecologists and women with regard to the integration of sexuality in consultations. A critical health psychology approach allows us to consider on the one hand sexuality as a construct that is inseparable from a given socio-historical context. On the other hand, this approach takes into consideration an embodied, social and psychological definition of human beings. Therefore, we used a mixed methods design that included two main research steps : First, we conducted 21 semi-structured interviews with male and female gynaecologists. In this phase, we also led 3 focus groups made up of 16 women aged from 21 to 65. Second, a survey was implemented (N= 421) based on findings stemming from the first phase. This allowed us to further analyse experiences on the integration of sexuality and to extend findings to a more diversified population of women. The data analysis allowed us to create a model that highlights the processes involved in the non integration of sexuality during gynaecological consultation. It shows a lack of training in sexology within medical programs. Moreover, it emphasises the mismatches on perceptions between gynaecologists and women concerning the gynaecologist's role ; intimacy, the issue of whether introducing sexuality topics, and finally, on the actual definition of sexuality itself. Our findings open new research perspectives for the study of sexuality by proposing a more integrative approach. They also provide practical and clinical perspectives concerning consultations in gynaecology.

"INTERMED": a method to assess health service needs. I. Development and reliability.

The purpose of this paper is to describe the development and to test the reliability of a new method called INTERMED, for health service needs assessment. The INTERMED integrates the biopsychosocial aspects of disease and the relationship between patient and health care system in a comprehensive scheme and reflects an operationalized conceptual approach to case mix or case complexity. The method is developed to enhance interdisciplinary communication between (para-) medical specialists and to provide a method to describe case complexity for clinical, scientific, and educational purposes. First, a feasibility study (N = 21 patients) was conducted which included double scoring and discussion of the results. This led to a version of the instrument on which two interrater reliability studies were performed. In study 1, the INTERMED was double scored for 14 patients admitted to an internal ward by a psychiatrist and an internist on the basis of a joint interview conducted by both. In study 2, on the basis of medical charts, two clinicians separately double scored the INTERMED in 16 patients referred to the outpatient psychiatric consultation service. Averaged over both studies, in 94.2% of all ratings there was no important difference between the raters (more than 1 point difference). As a research interview, it takes about 20 minutes; as part of the whole process of history taking it takes about 15 minutes. In both studies, improvements were suggested by the results. Analyses of study 1 revealed that on most items there was considerable agreement; some items were improved. Also, the reference point for the prognoses was changed so that it reflected both short- and long-term prognoses. Analyses of study 2 showed that in this setting, less agreement between the raters was obtained due to the fact that the raters were less experienced and the scoring procedure was more susceptible to differences. Some improvements--mainly of the anchor points--were specified which may further enhance interrater reliability. The INTERMED proves to be a reliable method for classifying patients' care needs, especially when used by experienced raters scoring by patient interview. It can be a useful tool in assessing patients' care needs, as well as the level of needed adjustment between general and mental health service delivery. The INTERMED is easily applicable in the clinical setting at low time-costs.

Medical futility at the end of life: the perspectives of intensive care and palliative care clinicians.

Objectives Medical futility at the end of life is a growing challenge to medicine. The goals of the authors were to elucidate how clinicians define futility, when they perceive life-sustaining treatment (LST) to be futile, how they communicate this situation and why LST is sometimes continued despite being recognised as futile. Methods The authors reviewed ethics case consultation protocols and conducted semi-structured interviews with 18 physicians and 11 nurses from adult intensive and palliative care units at a tertiary hospital in Germany. The transcripts were subjected to qualitative content analysis. Results Futility was identified in the majority of case consultations. Interviewees associated futility with the failure to achieve goals of care that offer a benefit to the patient's quality of life and are proportionate to the risks, harms and costs. Prototypic examples mentioned are situations of irreversible dependence on LST, advanced metastatic malignancies and extensive brain injury. Participants agreed that futility should be assessed by physicians after consultation with the care team. Intensivists favoured an indirect and stepwise disclosure of the prognosis. Palliative care clinicians focused on a candid and empathetic information strategy. The reasons for continuing futile LST are primarily emotional, such as guilt, grief, fear of legal consequences and concerns about the family's reaction. Other obstacles are organisational routines, insufficient legal and palliative knowledge and treatment requests by patients or families. Conclusion Managing futility could be improved by communication training, knowledge transfer, organisational improvements and emotional and ethical support systems. The authors propose an algorithm for end-of-life decision making focusing on goals of treatment.

Delay of extubation in neonates and children after cardiac surgery: impact of ventilator-associated pneumonia.

OBJECTIVE: This study was undertaken to determine the delay of extubation attributable to ventilator-associated pneumonia (VAP) in comparison to other complications and complexity of surgery after repair of congenital heart lesions in neonates and children. METHODS: Cohort study in a pediatric intensive care unit of a tertiary referral center. All patients who had cardiac operations during a 22-month period and who survived surgery were eligible (n = 272, median age 1.3 years). Primary outcome was time to successful extubation. Primary variable of interest was VAP Surgical procedures were classified according to complexity. Cox proportional hazards models were calculated to adjust for confounding. Potential confounders comprised other known risk factors for delayed extubation. RESULTS: Median time to extubation was 3 days. VAP occurred in 26 patients (9.6%). The rate of VAP was not associated with complexity of surgery (P = 0.22), or cardiopulmonary bypass (P = 0.23). The adjusted analysis revealed as further factors associated with delayed extubation: other respiratory complications (n = 28, chylothorax, airway stenosis, diaphragm paresis), prolonged inotropic support (n = 48, 17.6%), and the need for secondary surgery (n = 51, 18.8%; e.g., re-operation, secondary closure of thorax). Older age promoted early extubation. The median delay of extubation attributable to VAP was 3.7 days (hazards ratio HR = 0.29, 95% CI 0.18-0.49), exceeding the effect size of secondary surgery (HR = 0.48) and other respiratory complications (HR = 0.50). CONCLUSION: VAP accounts for a major delay of extubation in pediatric cardiac surgery.

Androgen dependence of hirsutism, acne, and alopecia in women: retrospective analysis of 228 patients investigated for hyperandrogenism.

Hirsutism, acne, alopecia, and oligo-amenorrhea are clinical expressions of hyperandrogenism, one of the most frequent endocrine disorders in women of reproductive age. Women referred to our endocrine clinics for skin symptoms of hyperandrogenism underwent a laboratory workup to evaluate hormone measurements and received antiandrogen therapy. We retrospectively analyzed the outcome of 228 consecutive patients investigated over 6 years.Patients with hirsutism had higher levels of androstenedione, dehydroepiandrosterone sulfate (DHEAS), and salivary testosterone; lower levels of sex hormone-binding globulin (SHBG); and a higher prevalence of oligo-amenorrhea than patients with alopecia, while patients with acne showed intermediate values. Hirsutism score correlated positively with androstenedione, DHEAS, and salivary testosterone, and correlated negatively with SHBG; salivary testosterone showed the highest correlation coefficient. Total testosterone was not significantly different among patients with hirsutism, alopecia, or acne, and did not significantly correlate with hirsutism score. Hirsutism and oligo-amenorrhea were the most sensitive symptoms of hyperandrogenism, and no androgenic parameter alone allowed us to identify all cases of hyperandrogenism.Patients of central European origin sought consultation with milder hirsutism scores than patients of southern European origin. There was, however, no difference in the clinical-biological correlation between these groups, arguing against differences in skin sensitivity to androgens.Polycystic ovary syndrome, defined as hyperandrogenism (hirsutism or elevated androgens) and oligo-amenorrhea, was diagnosed in 63 patients (27.6%), an underestimate compared with other reports that include systematic ovarian ultrasound studies. Neither pelvic ultrasound, used in a limited number of cases, nor the luteinizing hormone/follicle-stimulating hormone ratio helped to distinguish patients with polycystic ovary syndrome from the other diagnostic groups. These included hyperandrogenism (hirsutism or elevated androgens) and eumenorrhea (101 patients; 44.3%); normal androgens (acne or alopecia and eumenorrhea) (51 patients; 22.4%); isolated low SHBG (7 patients; 3.1%); nonclassical congenital adrenal hyperplasia (4 patients; 1.8% of total, 4.9% of patients undergoing cosyntropin stimulation tests); and ovarian tumor (2 patients; 0.9%).Ethinylestradiol and high-dose cyproterone acetate treatment lowered the hirsutism score to 53.5% of baseline at 1 year, and was also effective in treating acne and alopecia. The clinical benefit is ascribed to the peripheral antiandrogenic effect of cyproterone acetate as well as the hormone-suppressive effect of this combination. Salivary testosterone showed the most marked proportional decrease of all the androgens under treatment. Cost-effectiveness and tolerance of ethinylestradiol and high-dose cyproterone acetate compared well with other antiandrogenic drug therapies for hirsutism. The less potent therapy with spironolactone only, a peripheral antiandrogen without hormone-suppressive effect, was effective in treating isolated alopecia in patients with normal androgens.

The representations of adolescents about gynecological consultation

Objective: To analyze the social representation of adolescents about gynecological consultation and the influence of those in searching for consultations. Method: Qualitative descriptive study based on the Social Representations Theory, conducted with 50 adolescents in their last year of middle school. The data was collected between April and May of 2010 by Evocations and a Focal Group. The software EVOC and contextual analysis were used in the data treatment. Results: The elements fear and constraint, constant in the central nucleus, can justify the low frequency of adolescents in consultations. The term embarrassment in the peripheral system reinforce current sociocultural norms, while prevention, associated with learning about sex and clarifying doubts, allows to envision an educative function. Obtained testimonies in the focal groups exemplify and reinforce those findings. Conclusion: For an effective health education, professionals, including nurses, need to clarify the youth individually and collectively about their rights to privacy, secrecy, in addition to focus the gynecological consultation as a promotion measure to sexual and reproductive health.

Research priorities for nursing care of infants, children and adolescents: a West Australian Delphi study.

This paper describes a study that aimed to identify research priorities for the care of infants, children and adolescents at the sole tertiary referral hospital for children in Western Australia. The secondary aim was to stimulate nurses to explore clinical problems that would require further inquiry. Background. Planning for research is an essential stage of research development; involving clinicians in this exercise is likely to foster research partnerships that are pertinent to clinical practice. Nursing research priorities for the paediatric population have not previously been reported in Australia. Design. Delphi study. Method. Over 12 months in 2005-2006, a three-round questionnaire, using the Delphi technique, was sent to a randomly selected sample of registered nurses. This method was used to identify and prioritise nursing research topics relevant to the patient and the family. Content analysis was used to analyse Round I data and descriptive statistics for Round II and III data. Results. In Round I, 280 statements were identified and reduced to 37 research priorities. Analysis of data in subsequent rounds identified the top two priority research areas as (1) identification of strategies to reduce medication incidents (Mean = 6 center dot 47; SD 0 center dot 88) and (2) improvement in pain assessment and management (Mean = 6; SD 1 center dot 38). Additional comments indicated few nurses access the scientific literature or use research findings because of a lack of time or electronic access. Conclusions. Thirty-seven research priorities were identified. The identification of research priorities by nurses provided research direction for the health service and potentially other similar health institutions for children and adolescents in Australia and internationally. Relevance to clinical practice. The nurse participants showed concern about the safety of care and the well-being of children and their families. This study also enabled the identification of potential collaborative research and development of pain management improvement initiatives.

Development and validating an educational booklet for childbirth companions

Objective The article describes the steps in producing and validating an educational booklet for childbirth companions. Method Methodological study conducted in 2011 consisting of the following steps: situational assessment; establishing brochure content; content selection and referencing; drafting the text; design of illustrations; layout; consultation of specialists; consultation of target audience; amendments; proofreading; evaluation using the Flesch Reading Ease Formula. The topics portrayed the sequence of events involving support from gestation to the postpartum period. Results The concordance rate among companions was greater than or equal to 81.8% for the topics organisation, writing style, presentation and motives. The overall Content Validity Index of the booklet was 0.94. The booklet was classified as easy reading or very easy reading according to the results of the Flesch Reading Ease Formula. Conclusion The presentation and content of the manual were validated for use with the target audience by the specialists and representatives of the target audience.

Doubts of caregivers of children with cleft lip and palate on postoperative care after cheiloplasty and palatoplasty

Objective To identify the main doubts of caregivers of children with cleft lip and palate on postoperative care after cheiloplasty and palatoplasty. Method Cross-sectional study carried out in a reference hospital, between September and November 2012. The sample was composed of 50 individuals divided in two groups, of which 25 caregivers of children submitted to cheiloplasty, and 25 of children submitted to palatoplasty. The doubts were identified by an interview applied during the preoperative nursing consultation and were then categorized by similarity. Descriptive statistics was used for analysis of the outcomes. Results Concerning cheiloplasty, the doubts were related to feeding (36%), hygiene and healing (24% each), pain and infection (8% each). With regard to palatoplasty, the doubts were related to feeding (48%), hygiene (24%), pain (16%), bleeding (8%) and infection (4%). Conclusion The study evidenced the concern of caregivers in relation to feeding and care of the postoperative wound.

Implementing the intermed in a post-acute care rehabilitation clinic for traumatic injuries: Obstacles and benefits

In 2003, the INTERMED, an instrument to assess biopsycho- social case complexity and to direct care, was introduced in daily clinical practice in the .Clinique romande de réadaptation suvaCare., a national rehabilitation hospital for traumatic injuries, located in the French speaking part of Switzerland. The introduction of the INTERMED was easy to realize and no major obstacles hampered its systematic implementation. Up to now, about 2,000 patients have been evaluated with the INTERMED and are followed for different outcomes. The INTERMED improved not only patients. assessment by including relevant psychosocial aspects of the clinical situation, it also favoured interdisciplinary communication, enhanced work satisfaction of the nursing staff and allowed early identification and adaptation of treatment for the injured patient showing a high degree of case complexity. Upon follow up, patients with a high degree of case-complexity showed a less favourable outcome, i.e. more health care utilization and lower rates of return to work. In conclusion, the systematic implementation of the INTERMED enabled the reorganization of medical rehabilitation, anchored it in a bio-psycho-social framework, improving interdisciplinary communication and collaboration and ameliorated treatment outcome.

Opportunistic screening actions for breast cancer performed by nurses working in primary health care

Abstract OBJECTIVE To identify opportunistic screening actions for breast cancer performed by nurses working in primary health care units in Ribeirão Preto, São Paulo. METHOD Cross-sectional study with 60 nurses from 28 units, who had been working for at least one year in the public municipal health care network. Data were collected between December 2013 and March 2014, by means of a questionnaire, using descriptive analysis and the software IBM SPSS version 20 and Microsoft Excel 2010. RESULTS The results showed that 71.7% of the participants questioned their female patients as for risk factors for breast cancer, mainly during nursing consultation; 70.0% oriented users about the age to perform clinical breast exam, whereas 30.0% did not due to lack of knowledge and time; 60.0% explained about the age to perform mammogram; 73.3% did not refer patients with suspicious breast exam results to the referral department, citing scheduling as the main obstacle to referral. Educational activities were not performed by 78.3% of participants. CONCLUSION Investment is needed in professional training and management of breast cancer screening.
