Revisión sistemática de la literatura: efecto de los rellenos inyectables en la región periorbitaria

Introducción: El conocimiento actual de la fisiopatología del envejecimiento periorbitario justifica la aplicación de materiales de relleno inyectables, dado que se enfocan en la restauración del volumen perdido en esta zona, convirtiéndose en una excelente alternativa a procedimientos quirúrgicos que remueven el tejido excedente. Sin embargo los efectos y la seguridad de esta naciente tendencia terapéutica aún no se sustentan en una sólida base científica. El objetivo de esta revisión es identificar el material de relleno inyectable más adecuado para el manejo de los defectos volumétricos estéticos de la región periorbitaria. Metodología: Se realizó una búsqueda exhaustiva de los artículos indexados publicados del 1º de enero de 2.000 al 30 de septiembre de 2.013, en diversas bases de datos electrónicas, se seleccionaron catorce publicaciones, se extrajo la información referente a datos demográficos, la intervención, el seguimiento y los desenlaces y se realizó un análisis de 14 estudios que cumplieron los criterios. Resultados: Todos los artículos incluidos poseían un bajo nivel de evidencia y del grado de recomendación. Todos los materiales de relleno se asociaron a altos niveles de satisfacción para el paciente, adecuada mejoría de la apariencia estética y similares efectos colaterales, el ácido hialurónico fue el material de relleno inyectable más utilizado en la región periorbitaria. Discusión: Los materiales de relleno inyectable mejoran los defectos volumétricos estéticos de la región periorbitaria pero es necesaria mayor evidencia para determinar el tipo relleno más apropiado para esta condición.

Experiencia en nefrectomía: serie de casos de cuatro años

Introducción: Las indicaciones por las cuales un paciente requiere una nefrectomía son múltiples: las neoplasias, la hidronefrosis y la exclusión funcional son las principales. En manos expertas la nefrectomía es un procedimiento seguro, especialmente porque en la actualidad el abordaje por excelencia es realizar una técnica mínimamente invasiva con conservación de nefronas. Se presenta el análisis de la experiencia en Mederi, Hospital Universitario Mayor en esta intervención. Metodología: Se realizó una serie de casos de pacientes llevados a nefrectomía entre mayo de 2008 y mayo de 2012. Se incluyeron la totalidad de los casos. Resultados: Se analizaron 72 registros, 49 mujeres y 25 hombres; 13 de ellas fueron laparoscópicas. La edad promedio fue de 58,6 años. El tiempo medio operatorio fue 169,23 minutos (118-220 minutos). El sangrado operatorio promedio fue de 680,63 ml (IC95%: 2,83-1358 ml). El tiempo de hospitalización promedio fue de 4,88 días IC95%. La mayoría de los pacientes se distribuyeron en estadios medios de la enfermedad tumoral, con poco compromiso ganglionar y metástasis; el diagnóstico histológico y estadio dominante fueron el carcinoma de células renales grado 3 de Fuhrman respectivamente. Se reportan 13 casos de compromiso de la capsula de Gerota y 11 con compromiso del hilio. Discusión: La experiencia en nefrectomía de la institución es muy positiva por el bajo número de mortalidad y complicaciones. En cuanto a la técnica, es importante promover la técnica laparoscópica

Medical Student’s Use of Time During Clinical Clerkships and the Credits Based System

Introduction: Comprehensive undergraduate education in clinical sciences is grounded on activities developed during clerkships. To implement the credits system we must know how these experiences take place. Objectives: to describe how students spend time in clerkships, how they assess the educative value of activities and the enjoyment it provides. Method: We distributed a form to a random clustered sample of a 100 students coursing clinical sciences, designed to record the time spent, and to assess the educative value and the grade of enjoyment of the activities in clerkship during a week. Data were registered and analyzed on Excel® 98 and SPSS. Results: mean time spent by students in clerkship activities on a day were 10.8 hours. Of those, 7.3 hours (69%) were spent in formal education activities. Patient care activities with teachers occupied the major proportion of time (15.4%). Of the teaching and learning activities in a week, 28 hours (56%) were spent in patient care activities and 22.4 hours (44.5%) were used in independent academic work. The time spent in teaching and learning activities correspond to 19 credits of a semester of 18 weeks. The activities assessed as having the major educational value were homework activities (4.6) and formal education activities (4.5). The graded as most enjoyable were extracurricular activities, formal educational activities and independent academic work. Conclusion: our students spend more time in activities with patients than the reported in literature. The attending workload of our students is greater than the one reported in similar studies.

Indicadores del desempeño clínico fisioterapéutico en el manejo hospitalario temprano del accidente

Las oportunidades conocidas de intervenciones tempranas en los accidentes cardiocerebrovasculares (ACV) desde el punto de vista médico y de rehabilitación hacen necesario avanzar en la formulación de indicadores del desempeño clínico en el manejo fisioterapéutico hospitalario de una persona con ACV. Objetivo: identificar los indicadores de desempeño clínico fisioterapéutico en el manejo hospitalario temprano de personas sobrevivientes de ACV. Materiales y métodos: se trata de un estudio exploratorio descriptivo que indaga sobre las pruebas y prácticas fisioterapéuticas existentes, la evidencia científica sobre indicadores clínicos en ACV, los indicadores estándar y los posibles indicadores clínicos en el escenario. Se llevó a cabo una revisión sistemática de estudios descriptivos, guías de práctica clínica, revisiones sistemáticas, estudio de casos clínicos basados en la evidencia en bases de datos como Pubmed, Proquest, Pedro y en revistas electrónicas, además del análisis de datos epidemiológicos de la prevalencia del ACV en Colombia y en Chile, en páginas web de la Organización Mundial de la Salud, Ministerio de Salud y Departamento AdministrativoNacional de cada país. Resultados: la evidencia señala que la rehabilitación temprana del ACV debe iniciarse durante la hospitalización, tan pronto como el diagnóstico se establezca y los problemas que ponen en riesgo la vida del paciente estén controlados. Las prioridades en la intervención fisioterapéutica en ACV son prevenir las complicaciones (trombosis venosa, infecciones y dolor) y facilitar la movilización temprana. Actualizaciones recientes de estas directrices incluyen la rehabilitación temprana, en particular la movilidad luego de las veinticuatro horas posteriores al ACV.Las pruebas que sustentan los indicadores de desempeño en rehabilitación para la atención en la etapa subaguda del ACV son escasas. Conclusiones: se hace notoria la importancia de la atención temprana fisioterapéutica en el proceso agudo del paciente con ACV, puesto que la evidencia disponible resalta un mejor pronóstico para pacientes que son intervenidos por el área dentro de las primeras veinticuatro horas posteriores al evento y la importancia de los indicadores de atención del paciente, como la calidad y el tiempo de atención, la periodicidad y el aprovechamiento de la intervención dentro de la ventana temporal aguda de recuperación del paciente.

Comparación de indicador “demanda no atendida” en urgencias, antes y después del especialista en emergencias

El presente estudio evalúa si hay cambios importantes en el indicador DNA, sin pretender demostrar causalidad, durante dos años antes y tres años después de la participación del EE, mediante un análisis comparativo pareado entre grupos con recolección retrospectiva. Durante el desarrollo de la formación de la primera cohorte de residentes del programa de especialización en Medicina de Emergencias en Bogotá, el hospital base del posgrado contrató un especialista en emergencias graduado en Medellín del Instituto de Ciencias de la Salud (CES), como Jefe del SU, lo que fue visto como una oportunidad única para notar los cambios posteriores a su participación, si bien el estudio no se diseñó para evaluar causalidad directa, pues los múltiples factores que intervendrían y el riesgo de modificación del factor a estudiar eran muy altos como para proponerse un análisis multivariado prospectivo.

Impacto del horario laboral en la capacidad de atención en médicos de urgencias de la Fundación Santa Fe

Introducción: Se ha determinado que las jornadas laborales, generan un deterioro cognoscitivo y funcional en las personas, con la consecuente afectación en los servicios de salud, al ser una de las disciplinas que más se encuentran en riesgo de cometer errores durante sus procesos de atención. Es por esto que en el presente estudio se pretendió evaluar el impacto de la jornada laboral en la capacidad de atención de los médicos de urgencias. Metodología: Se realizó un estudio transversal aplicando el Psychomotor Vigilance Test, el cual evalúa la capacidad de atención de las personas después de realizar diferentes actividades según el tiempo de respuesta en milisegundos. Se tomó una muestra de la población del personal médico de urgencias de la Fundación Santa Fé de Bogotá, estableciendo una comparación del mismo paciente en los diferentes turnos. Resultados: En el presente estudio se documentó un tiempo de respuesta promedio al inicio de la jornada diurna de 436,6 ms (IC95% 401-477) y al final de 443,1 ms (IC95% 388-484). Con respecto a la jornada nocturna se documentó un tiempo de respuesta promedio inicial de 422,8 ms (IC95% 403-457) y al final de 467,44 ms (IC95% 423-501). Discusión: Encontramos diferencias estadísticamente significativas en cuanto al tiempo de respuesta entre la jornada diurna y nocturna. Por lo tanto es recomendable crear políticas de Estado que gestionen el horario laboral del personal de salud para que prime la seguridad y la calidad de atención en el paciente, evitando al máximo cualquier posibilidad de error médico

Porque a competência pedagógica conta : o reforço do papel da avaliação dos docentes na estratégia de desenvolvimento de um faculdade de medicina

“Poor teaching performance is tolerated, whereas poor quality in research or substandard patient care is not. It is time to professionalize teaching and education” (Steinert, 2005). A Faculdade de Medicina da Universidade de Coimbra (FMUC) é uma escola médica clássica, sem qualquer tradição na avaliação do ensino e com uma considerável resistência à introdução de mecanismos de auditoria de qualidade. Com o objectivo de contribuir para ultrapassar estas dificuldades, o regente da disciplina de Fisiopatologia, e membro do Departamento de Educação Médica (DEM) da FMUC, aplicou um questionário nessa disciplina. Este questionário foi concebido para cobrir dimensões relevantes na avaliação da qualidade de ensino: objectivos; conteúdos; materiais; métodos de ensino; instrumentos de avaliação; apresentação e preparação da aula. Foi pedido aos alunos que respondessem ao questionário no fim de cada aula teórica e cada aula teórico-prática. Foi recolhido um total de 2401 questionários (aulas teóricas=1210; aulas teórico-práticas= 1191). Os resultados são discutidos em termos das suas implicações para o desenvolvimento do pessoal docente, das políticas da Escola e para a promoção da qualidade de ensino, como uma contribuição tendente ao estabelecimento de um clima institucional que encoraje a liderança educacional, a inovação e a excelência.

A actuação do enfermeiro como gestor na unidade de terapia intensiva do Hospital Regional do Baixo Amazonas-Santarém-Pará-Brasil : um estudo de caso

Estudo descritivo que teve como objetivo avaliar a atuação do enfermeiro como gestor da Unidade de Terapia Intensiva do Hospital Regional do Baixo Amazonas Dr. Waldemar Pena – HRBA, o qual obteve o selo de Acreditado em Nível 1 em 2012. Para a obtenção dos dados utilizou-se um questionário elaborado com 10 perguntas subjetivas e aplicado aos enfermeiros gerentes que atuam nas Unidades de Terapia Intensiva e CTI do HRBA. Verificou-se nesse estudo que são indivíduos na faixa etária de 25 a 45 anos, com predominância do gênero feminino, com especialização em áreas diversas da enfermagem. Na atuação no setor de gerência, os enfermeiros estabelecem prioridades, direcionando sua equipe para os atendimentos assistenciais complexos aos pacientes, ficando o trabalho burocrático para ser realizado por último. Os entraves relatados são a insatisfação e o desgaste no exercício da função de gerente da unidade devido ao excesso de funcionários sem experiência em UTI, falta de autonomia, dupla jornada de trabalho, excesso de burocracia entre outras situações que se tornam motivos de estresse. Concluiu-se que a atuação do enfermeiro como gerente se respalda na função assistencial ao paciente através de cuidados diretos e indiretos e na organização dos trabalhos burocráticos na Unidade de Terapia Intensiva.

Ontology modeling for generation of clinical pathways

Purpose: Increasing costs of health care, fuelled by demand for high quality, cost-effective healthcare has drove hospitals to streamline their patient care delivery systems. One such systematic approach is the adaptation of Clinical Pathways (CP) as a tool to increase the quality of healthcare delivery. However, most organizations still rely on are paper-based pathway guidelines or specifications, which have limitations in process management and as a result can influence patient safety outcomes. In this paper, we present a method for generating clinical pathways based on organizational semiotics by capturing knowledge from syntactic, semantic and pragmatic to social level. Design/methodology/approach: The proposed modeling approach to generation of CPs adopts organizational semiotics and enables the generation of semantically rich representation of CP knowledge. Semantic Analysis Method (SAM) is applied to explicitly represent the semantics of the concepts, their relationships and patterns of behavior in terms of an ontology chart. Norm Analysis Method (NAM) is adopted to identify and formally specify patterns of behavior and rules that govern the actions identified on the ontology chart. Information collected during semantic and norm analysis is integrated to guide the generation of CPs using best practice represented in BPMN thus enabling the automation of CP. Findings: This research confirms the necessity of taking into consideration social aspects in designing information systems and automating CP. The complexity of healthcare processes can be best tackled by analyzing stakeholders, which we treat as social agents, their goals and patterns of action within the agent network. Originality/value: The current modeling methods describe CPs from a structural aspect comprising activities, properties and interrelationships. However, these methods lack a mechanism to describe possible patterns of human behavior and the conditions under which the behavior will occur. To overcome this weakness, a semiotic approach to generation of clinical pathway is introduced. The CP generated from SAM together with norms will enrich the knowledge representation of the domain through ontology modeling, which allows the recognition of human responsibilities and obligations and more importantly, the ultimate power of decision making in exceptional circumstances.

Intra-tumor heterogeneity: lessons from microbial evolution and clinical implications

Multiple subclonal populations of tumor cells can coexist within the same tumor. This intra-tumor heterogeneity will have clinical implications and it is therefore important to identify factors that drive or suppress such heterogeneous tumor progression. Evolutionary biology can provide important insights into this process. In particular, experimental evolution studies of microbial populations, which exist as clonal populations that can diversify into multiple subclones, have revealed important evolutionary processes driving heterogeneity within a population. There are transferrable lessons that can be learnt from these studies that will help us to understand the process of intra-tumor heterogeneity in the clinical setting. In this review, we summarize drivers of microbial diversity that have been identified, such as mutation rate and environmental influences, and discuss how knowledge gained from microbial experimental evolution studies may guide us to identify and understand important selective factors that promote intra-tumor heterogeneity. Furthermore, we discuss how these factors could be used to direct and optimize research efforts to improve patient care, focusing on therapeutic resistance. Finally, we emphasize the need for longitudinal studies to address the impact of these potential tumor heterogeneity-promoting factors on drug resistance, metastatic potential and clinical outcome.

Training on the use of a bespoke continuing professional development framework improves the quality of CPD records

BACKGROUND: Using continuing professional development (CPD) as part of the revalidation of pharmacy professionals has been proposed in the UK but not implemented. We developed a CPD Outcomes Framework (‘the framework’) for scoring CPD records, where the score range was -100 to +150 based on demonstrable relevance and impact of the CPD on practice. OBJECTIVE: This exploratory study aimed to test the outcome of training people to use the framework, through distance-learning material (active intervention), by comparing CPD scores before and after training. SETTING: Pharmacy professionals were recruited in the UK in Reading, Banbury, Southampton, Kingston-upon-Thames and Guildford in 2009. METHOD: We conducted a randomised, double-blinded, parallel-group, before and after study. The control group simply received information on new CPD requirements through the post; the active intervention group also received the framework and associated training. Altogether 48 participants (25 control, 23 active) completed the study. All participants submitted CPD records to the research team before and after receiving the posted resources. The records (n=226) were scored blindly by the researchers using the framework. A subgroup of CPD records (n=96) submitted first (before-stage) and rewritten (after-stage) were analysed separately. MAIN OUTCOME MEASURE: Scores for CPD records received before and after distributing group-dependent material through the post. RESULTS: Using a linear-regression model both analyses found an increase in CPD scores in favour of the active intervention group. For the complete set of records, the effect was a mean difference of 9.9 (95% CI = 0.4 to 19.3), p-value = 0.04. For the subgroup of rewritten records, the effect was a mean difference of 17.3 (95% CI = 5.6 to 28.9), p-value = 0.0048. CONCLUSION: The intervention improved participants’ CPD behaviour. Training pharmacy professionals to use the framework resulted in better CPD activities and CPD records, potentially helpful for revalidation of pharmacy professionals. IMPACT: • Using a bespoke Continuing Professional Development outcomes framework improves the value of pharmacy professionals’ CPD activities and CPD records, with the potential to improve patient care. • The CPD outcomes framework could be helpful to pharmacy professionals internationally who want to improve the quality of their CPD activities and CPD records. • Regulators and officials across Europe and beyond can assess the suitability of the CPD outcomes framework for use in pharmacy CPD and revalidation in their own setting.

Challenging the handover : recommendations for research and practice

Communicating nursing care during the patient's total hospital stay is a difficult task to achieve within the context of high patient turnover, a lack of overlap time between shifts, and time constraints. Clear and accurate communication is pivotal to delivering high quality care and should be the gold standard in any clinical setting. Handover is a commonly used communication medium that requires review and critique. This study was conducted in five acute care settings at a major teaching hospital. Using a grounded theory approach, it explored the use of three types of handover techniques (verbal in the office, tape-recorded, and bedside handovers). Data were obtained from semi-structured interviews with nurses and participant field observations. Textual data were managed using NUD-IST. Transcripts were critically reviewed and major themes identified from the three types of handovers that illustrated their strengths and weaknesses. The findings of this study revealed that handover is more than just a forum for communicating patient care. It is also used as a place where nurses can debrief, clarify information and update knowledge. Overall, each type of handover had particular strengths and limitations; however, no one type of handover was appraised as being more effective. Achieving the multiple goals of handover presents researchers and clinicians with a challenging task. It is necessary to explore more creative ways of conducting the handover of patient care, so that an important aspect of nursing practice does not get classified as just another ritual.

Who, when and where? Identification of patients at risk of an in-hospital adverse event: Implications for nursing practice

Patients who suffer an adverse event (AE) are more likely to die or suffer permanent disability. Many AEs are preventable. Nurses have long played a pivotal role in the prevention of AEs. Much of the literature to date pertains to the role of nurses in the prevention of AEs such as falls, pressure areas and deep vein thrombosis. Prominent risk factors for AEs are the presence of physiological abnormality, failure to recognize or correct physiological abnormality, advanced patient age and location of patient room. Ongoing physiological assessment of patients is a nursing responsibility and the assessment findings of nurses underpin many patient care decisions. The early recognition and correction of physiological abnormality can improve patient outcomes by reducing the incidence of AEs, making nurses' ability to identify, interpret and act on physiological abnormality a fundamental factor in AE prediction and prevention. This paper will examine the role of nurses in AE prevention, using cardiac arrest as an example, from the perspective of physiological safety; that is, accurate physiological assessment and the early correction of physiological abnormality.

Tensions and constraints for nurses in hospital-in-home programmes

Economic necessity constrains health-care expenditure and waiting lists for hospital treatments remain high. As a result, more care is delivered via alternative means, such as same-day surgery initiatives and home-care programmes. Acute care delivered in the home to patients who would otherwise require hospitalization is becoming an increasingly acceptable means of treatment. These Hospital-in-the-Home programmes offer increased comfort while delivering comparable outcomes to many patient groups. The purpose of this paper is to generate discussion concerning the tensions that exist for nurses who practice in the home under the auspices of acute-care institutions. Data drawn from field work that formed part of a critical ethnography is used to generate the discussion. The larger research project explored the constructions of the role of the nurse in four Hospital-in-the-Home programmes in Victoria, Australia. It will be argued that there is significant pressure exerted upon nurses to support the imperative to reduce bed days in acute hospitals by transferring people to their home. At times, this agenda clashes with the nurses’ professional commitment to provide holistic patient care yet the dilemmas are largely unacknowledged and/or unrecognized by the nurses despite the tension they generate.
