Different Perspectives of Spanish Patients and Professionals on How a Dialysis Unit Should Be Designed.

Aim: The opinion of hemodialysis patients, professionals and family members is rarely considered in the design of a hemodialysis unit. Purpose: To know and compare the opinion and preferences of patients, family members and professionals regarding the design of a dialysis unit and the potential activities they believe should be carried out during the session in order to provide architects with real information for the construction of a dialysis center. Patients and Methods: Anonymous and voluntary survey in electronic format addressed to patients, relatives and professionals belonging to the 18 hemodialysis centers of the renal foundation and to ALCER and its different delegations, in relation to leisure activities to be carried out in the dialysis center and preferred design of the treatment room. The results obtained between the patient-family group and the professionals were compared. Results: We received 331 responses, of which 215 were from patients and family members (65%) and 116 (35%) from professionals. The most represented category among professionals was nursing (53%), followed by assistants (24%) and physicians (12.9%). A higher proportion of patients (66%) preferred rooms in groups of 10-12 patients as opposed to professionals who preferred open-plan rooms (p<0.001). The options that showed the most differences between patients and professionals were chatting with colleagues and intimacy (options most voted by patients/families), versus performing group activities and visibility (professionals). Conclusion: The professionals' view of patients' needs does not always coincide with the patients' perception. The inclusion of the perspective of people with kidney disease continues to be a pending issue in which we must improve both patient organizations and professionals, and the opinion of professionals and patients must be included in the design of a dialysis unit and the activities to be developed in it.

Impacto de la pandemia por SARS-CoV2 en la actividad asistencial y en la salud del personal de hemodiálisis en las diferentes oleadas / Impact of the SARS-CoV-2 Pandemic on Dialysis Care Activity and the Health of Dialysis Staff During Different Waves

Introducción: Además de las consecuencias del SARS-CoV-2 sobre los pacientes renales infectados, mantener la actividad durante la pandemia ha supuesto todo un reto dada la escasez de personal por las ausencias por enfermedad. Objetivo: Analizar la incidencia de contagios por Covid-19 entre los profesionales de hemodiálisis, sus características y su repercusión en bajas laborales en las diferentes oleadas.Material y Método: Estudio observacional longitudinal desde el 3/03/2020 hasta el 23/04/2022 (776 días) en una media de 406 profesionales sanitarios y no sanitarios de 18 unidades de diálisis y dos unidades administrativas de apoyo de la Fundación Renal Iñigo Álvarez de Toledo.La recogida de datos se realizó a través de la comunicación de las distintas supervisoras al departamento de recursos humanos. Resultados: 179 profesionales de un promedio de 406 (44,1%) se infectaron en el periodo de estudio, siendo el 52% enfermeras, 25% auxiliares, 11% nefrólogos y 12% otros profesionales. Un 40,2% de los casos presentaron síntomas. Un total de 160 contagiados estuvo ausente por enfermedad (89,3%), con una media de 15,9±14,3 días. En el 71,6% se detectó un contacto estrecho (todos fuera de las unidades) y esta identificación de contactos fue creciente según avanzaban las oleadas, pasando de un 6,7% en la 1ª ola a un 40% en la 6ª ola (p=0,016). Conclusiones: La sintomatología ha sido leve, al menos de dos semanas de ausencia por enfermedad; los contactos estrechos detectados han sido fundamentalmente comunitarios, sin registrarse contagios a través de los pacientes renales en las unidades.

Introduction: In addition to the consequences of SARS-CoV-2 infection in renal patients, maintaining dialysis activity during the pandemic has been a significant challenge due to staff shortages resulting from illness-related absences. Objetives: To analyze the incidence of COVID-19 infections among hemodialysis professionals, their characteristics, and their impact on work absences during different waves of the pandemic.Material and Method: Longitudinal observational study conducted from March 3, 2020, to April 23, 2022 (776 days), involving an average of 406 healthcare and non-healthcare professionals from 18 dialysis units and two administrative support units of the Renal Foundation. Data collection was carried out through communication from various supervisors to the human resources department.Results: During the study period, 179 professionals out of an average of 406 (44.1%) became infected. Among these, 52% were nurses, 25% were nursing assistants, 11% were nephrologists, and 12% were other professionals. 40.2% of cases exhibited symptoms. A total of 160 infected individuals were absent from work due to illness (89.3%), with an average duration of 15.9 ± 14.3 days. In 71.6% of cases, close contacts were identified outside the dialysis units, and this contact identification increased with each wave of the pandemic, rising from 6.7% in the 1st wave to 40% in the 6th wave (p=0.016).Conclusions: The symptoms have generally been mild, with absences from work lasting at least two weeks. Close contacts were mainly identified within the community, and there were no recorded infections transmitted through renal patients in the units. (AU)

Chronic Kidney Disease-Associated Pruritus and Quality of Life: Learning from Our Patients.

Chronic kidney disease-associated pruritus is itching directly related to kidney disease that cannot be explained by any other condition. Despite technological advances in the different aspects of dialysis sessions and the best treatment for chronic kidney disease patients, it is still a common problem in our patients. The many complex physiological mechanisms involved, the different hypotheses made over the years on the aetiology of the condition, and the great clinical variability may partially explain the limited knowledge about this problem and the difficulties in treating it. The presence of all these factors leads to the persistence of unpleasant symptoms, which must affect the disease burden and quality of life of kidney patients. Through the presentation of an illustrative clinical case, the aim of this review article is to highlight the need for adequate diagnosis and an improved approach to all aspects of chronic kidney disease-associated pruritus, in view of the heavy burden of the disease and the huge impact on the patient's quality of life.

Perception of Spanish nephrologists on an old unsolved problem: Pruritus associated with chronic kidney disease (CKD-aP).

INTRODUCTION: Pruritus associated with chronic kidney disease is defined as the sensation of itching, in people with chronic kidney disease, in a one area or all over the body that causes the need to scratch, after having ruled out other dermatological or systemic causes. It is an old and known problem whose prevalence has been able to decrease with the improvement of dialytic techniques but which still persists and is underdiagnosed. OBJECTIVES: The objective of this study was to analyse the current perception of nephrologists about this problem that influences the quality of life of people with chronic kidney disease through a survey. RESULTS: 135 nephrologists, most of them engaged in haemodialysis, participated. 86% considered that pruritus associated with chronic kidney disease is still a problem today that affects the quality of life. Most nephrologists believe that the main pathophysiological cause is uremic toxins (60%) and only 16% believe that it is due to the dysregulation of the opioid system/endorphins-dynorphins. Only 16% comment that the prevalence of pruritus in their centre is greater than 20%. 40% believe that the diagnosis is made because it is manifested by the patient and only 27% because it is asked by the doctor. Moreover, it is not usual to use scales to measure it or the codification in the medical records. The main treatment used is antihistamines (96%), followed by moisturizers/anaesthetics (93%) and modification of the dialysis regimen (70%). CONCLUSIONS: Pruritus associated with chronic kidney disease is still a current problem, it is underdiagnosed, not codified and with a lack of indicated, effective and safe treatments. Nephrologists do not know its real prevalence and the different pathophysiological mechanisms involved in its development. Many therapeutic options are used with very variable results, ignoring their efficacy and applicability at the present time. The new emerging kappa-opioid-receptor agonist agents offer us an opportunity to reevaluate this age-old problem and improve the quality of life for our patients with chronic kidney disease.

Percepción de los nefrólogos españoles sobre un problema antiguo no resuelto: Prurito asociado a la enfermedad renal crónica (Pa-ERC) / Perception of Spanish nephrologists on an old unsolved problem: Pruritus associated with chronic kidney disease (CKD-aP)

Introducción: El prurito asociado a enfermedad renal crónica se define como la sensación desagradable que provoca la necesidad de rascarse en una parte del cuerpo o en todo en personas con enfermedad renal crónica, tras haberse descartado otras causas dermatológicas o sistémicas. Es un problema antiguo y conocido cuya prevalencia ha podido disminuir con la mejoría de la eficacia dialítica pero que todavía persiste y está infradiagnosticado. Objetivos: El objetivo de este estudio fue analizar la percepción y práctica actual de los nefrólogos sobre este problema que impacta en la calidad de vida de las personas con enfermedad renal crónica a través de una encuesta anónima. Resultados: Participaron 135 nefrólogos, la mayoría dedicados a hemodiálisis. Un 86% consideró que el prurito asociado a enfermedad renal crónica sigue siendo un problema en la actualidad que afecta a la calidad de vida. La mayoría de los nefrólogos opinan que la principal causa fisiopatológica son las toxinas urémicas (60%) y solo un 16% cree que se debe a la desregulación del sistema opioide/endorfinas-dinorfinas. Únicamente un 16% comenta que la prevalencia de prurito en su centro es mayor del 20%. Un 40% cree que el diagnóstico se realiza porque lo manifiesta el paciente y solo un 27% porque lo pregunta el facultativo. Además, no es habitual usar escalas ni codificarlo en la historia clínica. El tratamiento más común son los antihistamínicos (96%), seguido de las cremas hidratantes/anestésicas (93%) y la modificación de la pauta de diálisis (70%). (AU)

A cost-effectiveness analysis of the introduction of a specialised consultation with duplex ultrasound assessment prior to vascular access surgery for haemodialysis.

INTRODUCTION: Duplex ultrasound (DUS) is increasingly used before vascular access (VA) surgery for haemodialysis. However, the cost-effectiveness of this approach is unknown. Our objective was to assess whether the introduction of a specialised consultation with DUS assessment modifies the cost and the time delay to achieve a first VA valid for haemodialysis. PATIENTS AND METHODS: Prospective cohort of patients undergoing a first VA (June 2014-July 2017) after a specialised consultation with DUS (ECO group). They were compared with a historical cohort (January 2012-May 2014) where VA was indicated exclusively by clinical evaluation (CLN group). We analysed the cost related to visits, DUS assessments, interventions, hospital admissions and graft materials to achieve a first VA valid for haemodialysis at least during 1 month. RESULTS: 86 patients in the CLN group were compared with 92 in the ECO group. Patients in the ECO group were younger (68.4 vs. 64.0 years; P=.038) but no other differences were seen among groups. The average cost to achieve a first AV valid for haemodialysis was significantly lower in the ECO group (2707 vs. 3347€; P=.024). There was a higher cost associated with DUS assessments in the ECO group yet the CLN group had a higher cost related to follow-up visits, successive surgical interventions, prosthetic material, days of hospital admission and catheters. The mean time needed to achieve a first AV valid for haemodialysis was also shorter in the ECO group (49.9 vs. 82.9 days, P=.002). CONCLUSION: The introduction of a specialised vascular access consultation with DUS prior to VA surgery has reduced the cost necessary to achieve a first VA valid for haemodialysis. From the patient's point of view this has meant less interventions and hospital admissions and a shortening of the time delay.

Impact of the COVID pandemic on vascular access creation for haemodialysis in 16 Spanish haemodialysis centres.

Background: The coronavirus disease (COVID) pandemic has resulted in a major disruption in healthcare that has affected several medical and surgical specialties. European and American Vascular Societies have proposed deferring the creation of an elective vascular access (VA) [autologous or prosthetic arteriovenous fistula (AVF) or arteriovenous graft (AVG)] in incident patients on haemodialysis (HD) in the era of the COVID pandemic. The aim of this study is to examine the impact of the COVID pandemic on VA creation and the central venous catheter (CVC)-related hospitalizations and complications in HD patients dialyzed in 16 Spanish HD units of three different regions. Methods: We compared retrospectively two periods of time: the pre-COVID (1 January 2019-11 March 2020) and the COVID era (12 March 2020-30 June 2021) in all HD patients (prevalent and incident) dialyzed in our 16 HD centres. The variables analysed were type of VA (CVC, AVF and AVG) created, percentage of CVC in incident and prevalent HD patients, CVC-related hospitalizations and complications (infection, extrusion, disfunction, catheter removal) and percentage of CVC HD sessions that did not reach the goal of Kt (>45) as a marker of HD adequacy. Results: A total of 1791 VAs for HD were created and 905 patients started HD during the study period. Patients who underwent vascular access surgery during the COVID period compared with pre-COVID period were significantly younger, with a significant decrease in surgical activity to create AVFs and AVGs in older HD patients (>75 and >85 years of age). There was a significant increase in CVC placement (from 59.7% to 69.5%; P < 0.001) from the pre-COVID to the COVID period. During the COVID pandemic, a significantly higher number of patients started HD through a CVC (80.3% versus 69.1%; P < 0.001). The percentage of CVC in prevalent HD patients has not decreased in the 19 months since the start of the pandemic [414 CVC/1058 prevalent patients (39.4%)]. No significant changes were detected in CVC-related hospitalizations between the pre-COVID and COVID periods. In the COVID period, a significant increase in catheter replacement and the percentage of HD session that did not reach the HD dose objective (Kt > 45) was observed. Conclusions: COVID has presented a public health system crisis that has influenced VA for HD, with an increase in CVCs relative to AVFs. A decrease in HD sessions that did not reach the HD dose objective was observed in the COVID period compared with a pre-COVID period.

Impacto de la introducción de una consulta específica con valoración eco-doppler en el costo asociado a la obtención de un primer acceso vascular para hemodiálisis / A cost-effectiveness analysis of the introduction of a specialised consultation with duplex ultrasound assessment prior to vascular access surgery for haemodialysis

Introducción: La valoración mediante eco-doppler (ED) previa a la realización de un acceso vascular (AV) está cada vez más extendida, pero existen pocos estudios que aborden su coste/efectividad. Nuestro objetivo fue evaluar si la introducción de una consulta específica de AV con ED modifica el coste, los tiempos de demora, el número de re-intervenciones e ingresos para lograr un primer AV útil.Pacientes y métodosCohorte prospectiva de pacientes sometidos a un primer AV (junio 2014-julio 2017), a quienes se practicó un ED preoperatorio (grupo ECO). Se compararon con una cohorte histórica (enero 2012-mayo 2014) de primeros AV indicados exclusivamente mediante valoración clínica (grupo CLN). Se calcularon los costes de realización y el seguimiento para lograr un AV útil para hemodiálisis durante como mínimo un mes sin complicaciones.ResultadosSe compararon 86 pacientes del grupo CLN con 92 del ECO, siendo estos últimos más jóvenes (68,4 vs. 64,0 años; p=0,038). El coste medio del grupo ECO fue significativamente inferior (ECO=2.707 vs. CLN=3.347€; p=0,024). El grupo ECO tuvo un coste mayor en ecografías preoperatorias y de seguimiento. El grupo CLN tuvo un coste superior respecto a consultas de seguimiento, intervenciones quirúrgicas sucesivas, material protésico, días de ingreso y catéteres. Se disminuyó el tiempo de demora para la realización del AV (CLN=82,9 vs. ECO=49,9 días; p=0,002).ConclusiónLa introducción de una consulta específica de AV para hemodiálisis con valoración ED, ha permitido disminuir el coste para lograr un primer AV útil, como consecuencia de una reducción en los tiempos de demora, visitas de control, re-intervenciones, días de ingreso e implantación de catéteres.

Mortality in Hemodialysis Patients with COVID-19, the Effect of Paricalcitol or Calcimimetics.

BACKGROUND: In COVID-19 patients, low serum vitamin D (VD) levels have been associated with severe acute respiratory failure and poor prognosis. In regular hemodialysis (HD) patients, there is VD deficiency and markedly reduced calcitriol levels, which may predispose them to worse outcomes of COVID-19 infection. Some hemodialysis patients receive treatment with drugs for secondary hyperparathyroidism, which have well known pleiotropic effects beyond mineral metabolism. The aim of this study was to evaluate the impact of VD status and the administration of active vitamin D medications, used to treat secondary hyperparathyroidism, on survival in a cohort of COVID-19 positive HD patients. METHODS: A cross-sectional retrospective observational study was conducted from 12 March to 21 May 2020 in 288 HD patients with positive PCR for SARS-CoV2. Patients were from 52 different centers in Spain. RESULTS: The percent of HD patients with COVID-19 was 6.1% (288 out of 4743). Mortality rate was 28.4% (81/285). Three patients were lost to follow-up. Serum 25(OH)D (calcidiol) level was 17.1 [10.6-27.5] ng/mL and was not significantly associated to mortality (OR 0.99 (0.97-1.01), p = 0.4). Patients receiving active vitamin D medications (16/94 (17%) vs. 65/191(34%), p = 0.003), including calcimimetics (4/49 (8.2%) vs. 77/236 (32.6%), p = 0.001), paricalcitol or calcimimetics (19/117 (16.2%) vs. 62/168 (36.9%); p < 0.001), and also those on both paricalcitol and calcimimetics, to treat secondary hyperparathyroidism (SHPTH) (1/26 (3.8%) vs. 80/259 (30.9%), p < 0.001) showed a lower mortality rate than patients receiving no treatment with either drug. Multivariate Cox regression analysis confirmed this increased survival. CONCLUSIONS: Our findings suggest that the use of paricalcitol, calcimimetics or the combination of both, seem to be associated with the improvement of survival in HD patients with COVID-19. No correlation was found between serum VD levels and prognosis or outcomes in HD patients with COVID-19. Prospective studies and clinical trials are needed to support these findings.

Impact of a Nosocomial COVID-19 Outbreak on a Non-COVID-19 Nephrology Ward during the First Wave of the Pandemic in Spain.

INTRODUCTION: The aim of this study was to analyze a nosocomial coronavirus disease 2019 (COVID-19) outbreak that occurred on a polyvalent non-COVID-19 ward at a tertiary care university hospital in Spain during the first wave of the pandemic and to describe the containment measures taken. The outbreak affected healthcare workers (HCWs) and kidney disease patients including transplant patients and those requiring maintenance hemodialysis. METHODS: The outbreak investigation and report were conducted in accordance with the Orion statement guidelines. RESULTS: In this study, 15 cases of COVID-19 affecting 10 patients and 5 HCWs were identified on a ward with 31 beds and 43 HCWs. The patients had tested negative for severe acute respiratory syndrome coronavirus 2 infection on admission. One of the HCWs was identified as the probable index case. Five patients died (mortality rate, 50%). They were all elderly and had significant comorbidities. The infection control measures taken included the transfer of infected patients to COVID-19 isolation wards, implementation of universal preventive measures, weekly PCR testing of patients and HCWs linked to the ward, training of HCWs on infection control and prevention measures, and enhancement of cleaning and disinfection. The outbreak was contained in 2 weeks, and no new cases occurred. CONCLUSION: Nosocomial COVID-19 outbreaks can have high attack rates involving both patients and HCWs and carry a high risk of patient mortality. Hospitals need to implement effective infection prevention and control strategies to prevent nosocomial COVID-19 spread.

Dependencia para las actividades instrumentales de la vida diaria en pacientes en hemodiálisis: influencia sobre la calidad de vida relacionada con la salud / Disability in instrumental activities of daily living in hemodialysis patients: Influence on quality of life related to health

INTRODUCCIÓN: Las actividades instrumentales de la vida diaria (AIVD) requieren un mayor nivel de autonomía personal e interacción con el entorno que las actividades básicas de la vida diaria (ABVD). Pocos estudios analizan el déficit funcional en AIVD. La detección temprana del déficit es importante, pues una acción temprana puede retrasar la evolución del proceso de dependencia. OBJETIVO: El objetivo de este estudio fue conocer la prevalencia de déficit funcional en AIVD de pacientes en hemodiálisis (HD), su relación con el déficit funcional en la ABVD y su influencia en la calidad de vida relacionada con la salud (CVRS). MÉTODOS: Estudio transversal en 66 pacientes en HD. Se utilizaron diferentes escalas: Lawton y Brody (dependencia AIVD), Delta (dependencia ABVD), y COOP-WONCA (CVRS). Se recogieron datos clínicos (edad, sexo, etiología de la ERC, meses en HD, estado civil, situación laboral). RESULTADOS: El 80,3% de los pacientes estudiados tenía algún grado de dependencia para el AIVD (57,5% en grado moderado/severo) y 40,8% para el ABVD (9% en grado moderado/severo). Ambos tipos de dependencia mostraron correlación (R: -0.583; p = 0,000). La edad y la situación laboral influyen en la dependencia de las AIVD y las ABVD. Los pacientes con mayor dependencia de la AIVD tuvieron una peor CVRS (p < 0,000) con mayores diferencias en las dimensiones: "actividades diarias", "actividades sociales" y "apoyo social". CONCLUSIONES: Los pacientes de HD presentan más dependencia a las AIVD que a las ABVD, y con mayor severidad y ambos tipos de dependencia influyen sobre la CVRS. Detectar precozmente la discapacidad en las AIVD puede servir para iniciar programas de intervención y prevenir, revertir o retrasar la progresión

INTRODUCTION: Instrumental Activities of Daily Life (IADL) requires a higher level of personal autonomy and interaction with the environment than the basic activities of daily life (BADL). Few studies analyze the deficit on IADL. Early detection is important because an early action can delay the evolution of the dependency process. AIM: to know the prevalence of functional deficit in IADL of hemodialysis patients, its relationship with the functional deficit in the BADL and its influence on the health related quality of life (HRQoL). METHODS: Cross-sectional study in 66 patients on HD. Different scales were used: Lawton and Brody (AIVD dependency), Delta (BADL dependency), and COOP-WONCA (HRQOL). Clinical data were collected (age, sex, CKD etiology, months in HD, marital status, employment situation). RESULTS: 80.3% of the patients had some degree of dependence for the IADL (57.5% in moderate/severe degree) and 40.8% for the BADL (9% in moderate/severe degree). There was a correlation between dependence to the BADL and AIVD. Age and employment status influence the dependence on IADL and BADL. Patients with greater dependence on IADL had worse HRQoL (P < .000). The dimensions in which they showed greater differences were "Daily activities", "Social activities" and "Social support". CONCLUSIONS: HD patients are more dependent on IADL than on ADL and with a higher degree of severity and the level of dependence in both types of activities has important influence on HRQoL. Early detection of the occurrence of disability in the realization of IADL can be used to initiate intervention programs that help to prevent, reverse or delay the progression

Estrategias para aumentar la seguridad del paciente en hemodiálisis: Aplicación del sistema de análisis modal de fallos y efectos (sistema AMFE) / Strategies to increase patient safety in Hemodialysis: Application of the modal analysis system of errors and effects (FEMA system)

Antecedentes: La población en hemodiálisis (HD) es de alto riesgo. En estos pacientes un fallo puede tener consecuencias catastróficas, por lo que son necesarios sistemas que garanticen su seguridad en un entorno con alta tecnología y gran interacción del factor humano. Objetivos: Mostrar una sistemática de trabajo, reproducible en cualquier unidad de HD, que consiste en registrar las complicaciones y fallos ocurridos durante la sesión, definir cuáles de estas complicaciones podrían ser consideradas eventos adversos (EA) y, por tanto, prevenibles y realizar un análisis sistemático tanto de ellos como de los fallos reales o potenciales subyacentes, evaluando su gravedad, frecuencia y detección, y estableciendo prioridades de actuación (sistema de análisis modal de fallos y efectos [AMFE]). Métodos: Examen retrospectivo de las gráficas de diálisis de todas las sesiones practicadas durante un mes (octubre de 2015) en 97 pacientes, y análisis de las complicaciones registradas. La consideración de estas complicaciones como EA se basó en el consenso entre 13 profesionales y 2 pacientes. Se valoró la severidad, frecuencia y detección de cada fallo real o potencial mediante el sistema AMFE. Resultados: Se practicaron 1.303 sesiones de HD en 97 pacientes en las que se registraron un total de 383 complicaciones (1 cada 3,4 tratamientos). De ellas, el 87,9% fueron consideradas EA y el 23,7% complicaciones relacionadas con la enfermedad de base. Se detectó un EA cada 3,8 tratamientos. Los EA más frecuentes fueron la hipertensión y la hipotensión (42,7 y 27,5% del total de EA registrados, respectivamente). Los EA relacionados con el acceso vascular fueron uno de cada 68,5 tratamientos. Se registraron un total de 21 fallos en la asistencia (1 cada 62 tratamientos), los cuales estaban relacionados con fallos en la aplicación de la técnica y en la administración de la medicación. El mayor número de prioridad de riesgo lo obtuvieron los fallos relacionados con errores en el peso, disfunción o rotura del catéter y salida de agujas. Conclusiones: Las complicaciones en HD son frecuentes y la consideración de algunas de ellas como EA podría mejorar la seguridad en la asistencia, al poner en marcha medidas preventivas. La implementación del sistema AMFE permite estratificar y priorizar los posibles fallos de las unidades de diálisis, y actuar con mayor o menor premura, desarrollando las acciones de mejora necesarias (AU)

Background: Haemodialysis (HD) patients are a high-risk population group. For these patients, an error could have catastrophic consequences. Therefore, systems that ensure the safety of these patients in an environment with high technology and great interaction of the human factor is a requirement. Objectives: To show a systematic working approach, reproducible in any HD unit, which consists of recording the complications and errors that occurred during the HD session; defining which of those complications could be considered adverse event (AE), and therefore preventable; and carrying out a systematic analysis of them, as well as of underlying real or potential errors, evaluating their severity, frequency and detection; as well as establishing priorities for action (Failure Mode and Effects Analysis system [FMEA systems]). Methods: Retrospective analysis of the graphs of all HD sessions performed during one month (October 2015) on 97 patients, analysing all recorded complications. The consideration of these complications as AEs was based on a consensus among 13 health professionals and 2 patients. The severity, frequency and detection of each AE was evaluated by the FMEA system. Results: We analysed 1303 HD treatments in 97 patients. A total of 383 complications (1 every 3.4 HD treatments) were recorded. Approximately 87.9% of them was deemed AEs and 23.7% complications related with patients'underlying pathology. There was one AE every 3.8 HD treatments. Hypertension and hypotension were the most frequent AEs (42.7 and 27.5% of all AEs recorded, respectively). Vascular-access related AEs were one every 68.5 HD treatments. A total of 21 errors (1 every 62 HD treatments), mainly related to the HD technique and to the administration of prescribed medication, were registered. The highest risk priority number, according to the FMEA, corresponded to errors related to patient body weight; dysfunction/rupture of the catheter; and needle extravasation. Conclusions: HD complications are frequent. Consideration of some of them as AEs could improve safety by facilitating the implementation of preventive measures. The application of the FMEA system allows stratifying real and potential errors in dialysis units and acting with the appropriate degree of urgency, developing and implementing the necessary preventive and improvement measures (AU)

Gestión de calidad en nefrología en España / Quality management of nephrology in Spain

Quality control and management systems have gradually been incorporated into Spanish health care system. Ambulatory dialysis centers have been pioneers of this kind of systems in nephrology, on the one hand, due to professional needs to establish the utmost control of each process of the activity, and on the other, urged by the requirements of government services. This has given rise to the recent creation of a multidisciplinary task force for Quality Management fostered by the Sociedad Española de Nefrología (Spanish Nephrology Association). Work started by receiving information of the initial stages of nephrology services and dialysis units in the country by means of a survey regarding the use of quality management systems and a follow up of the indicators. In addition, the goal was to stimulate hospital units and peripheral dialysis centers so as to incorporate proper tools for quality management in their practices and to define health care procedures and their indicators. This work also aimed at establishing consensual monitoring plans to allow comparisons of the results between different centers that might become a reference for future areas of improvement bridging the gap between the development of guides and their later follow up. In this article the advances made in this regard are reviewed.

Los sistemas de control y gestión de la calidad se han incorporado progresivamente al mundo sanitario en España y los centros de hemodiálisis extrahospitalarios concertados han sido pioneros en este campo en el terreno de la Nefrología; por un lado, por una necesidad profesional de asegurar al máximo el control de cada proceso de la actividad que realizan, y por otro, impulsados por los requerimientos de la administración pública. Todo esto ha motivado la reciente creación de un grupo de trabajo multidisciplinario sobre Gestión de la Calidad, impulsado por la Sociedad Española de Nefrología, el cual inició su andadura evaluando, mediante una encuesta, la situación de partida en los servicios de Nefrología y las unidades de hemodiálisis de ámbito nacional, con respecto a la utilización de sistemas de gestión de calidad y al seguimiento de indicadores. Además, tenía como objetivo estimular a las unidades hospitalarias y a los centros de diálisis periféricos a incorporar las herramientas de gestión de la calidad en su práctica, definir los diferentes procesos asistenciales y sus indicadores, y establecer planes de monitorización consensuados que permitieran comparar resultados entre diferentes centros y que sirvieran como punto de referencia para futuras áreas de mejora, dando el salto entre la elaboración de guías y su monitorización posterior. En este trabajo se resumen los avances realizados en este sentido.
