Authors: Alsheameri Aliyaa M. , Alsaad Aymen J. , Rasheed Laith Sh.
Published: April 2023

This paper presents and evaluates a new method for producing Slurry Infiltrated Fiber Concrete (SIFCON). A study was carried out to investigate the impact on the mechanical properties of SIFCON, where several cubes, cylinders, and prisms were cast to compare the proposed gradual and the traditional multi-layer method using the same mixing proportions: 6% straight steel fiber, cement, sand, 10% silica fume replacement, and 2.4% superplasticizer. The results showed that when using the proposed gradual mix method, compressive strength, splitting tensile strength, modulus of elasticity, and modulus of rupture improved by 15.21%, 8.06%, 9.07%, and 5.26% compared to the traditional multi-layer method.

Authors: Hiremath Neelambika B. , Dayananda Pruthviraja
Published: April 2023

Differential gene expression is an analysis of gene data, in which the RNA sequence data after next-generation sequencing are to be visualized for any quantitative changes in the levels of the experimental data set. This work aims to derive the transcript statistics on a gene transcript file with a fold change of genes on a normalized scale, in order to identify quantitative changes in gene expression of the difference between the reference genome and Non-Small Cell Lung Cancer (NSCLC) samples. This insight makes a clinical impact in assessing and characterizing candidate genes. The pipeline comprises tuxedo protocol and programming language R with the standard ballgown package. The resultant data set and the plot displays depict the candidate genes in their respective location which are significant in expressing their changes in NSCLC samples. The samples are compared with prominent gene labels of NSCLC samples. The results explain the differential expression of particular samples across samples from both genders.

Published: April 2023

The coronavirus outbreak (COVID-19) has caused a sharp increase in the use of Single-Use Surgical Face Masks (SUSFMs) as personal protective equipment. These eventually end up in waste disposal facilities causing environmental pollution. Those that end up in the water bodies fragment into microplastics that affect marine life. Since the SUSFM materials are made from polypropylene, a thermoplastic polymer material that takes a long time to degrade, it is important to develop sustainable mitigation measures to remove them from the environment. This study investigated the feasibility of reutilizing SUSFMs in concrete. SUSFMs were shredded and added to C30/37 grade concrete in various percentages, 0%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, and 3.0%, by mass of cement content. The specimens were cured for 28 days before being tested for compressive strength, splitting tensile strength, and ultrasonic pulse velocity. The compressive strength decreased with an increase in the length and dosage content. The least decrease of 10.4% was observed at 0.5% content of 30mm length of SUSFM material. The results showed that concrete improved regarding splitting tensile strength, with the highest increase of 15.2% at 0.5% content of 30mm SUSFM. In addition, the overall quality of concrete remains at UPV values of more than 4000m/s registering good quality concrete. The results underscore the use SUSFM material in concrete in order to improve its quality while at the same time reducing waste.

Indian Railway’s: Finance and Revenue Management Approach
Authors: Mohhammed Wasim Khan  , Dr. Harish Purohit
Published: April 2023

Indian Railways has the fourth largest rail network in the world after the United States, China and Russia. In the last few decades, traffic has been moving to other transport modes such as roads and air, which has led to declining rail traffic, and consequently declining revenue generation for the Railways. Deteriorating finances of the Railways have translated into lower investment in infrastructure, poor infrastructure maintenance, and poor services. Poor infrastructure has also had serious implications in the form of train accidents. The Comptroller and Auditor General of India conducted a compliance audit for the year 2016-17, which has been tabled in Parliament. In this context, the note looks at the Railways finances and challenges to financing, the Railways infrastructure, and the current organizational structure of the Railways and the reforms suggested to restructure it. In 2021-22, the total revenue expenditure by Railways was estimated at Rs. 2, 10,899 crore which was an annual increase of 10% over 2019-20. While the total proposed capital expenditure for 2021-22 was Rs 2, 15,058 crore. This was an annual increase of 21% over 2019-20.
Феномен пантоміми та проблема перевтілення актора-міма у сценічний образ
Authors: KUZMENKO Halyna , SPODONEIKO KATERYNA
Published: April 2023

Основним завданням статті є спроба актуалізувати питання, що постали навколо пантоміми, – одного з видів сценічного мистецтва, який в історії театру відіграє особливе значення, оскільки вважається одним із найважливіших факторів у його створенні та становленні. Висвітлено питання термінологізації, смислового наповнення категорій: «пантоміма», «сценічний образ артиста-міма», «стилізація». Розкрито специфічні властивості пантоміми як особливого типу видовищної культури сьогодення та особливості її художньої мови. Зазначено, що особлива – органічна й унікальна художня мова цього виду мистецтва служать засобом комунікації між артистом-мімом і глядачем. Автори підкреслюють, що сучасний мім – це універсальний артист-перформер, якому підвладні як невимушені комедійні скетч-шоу, короткі естрадні моно-сценки з уявними предметами й нехитрим розвитком подій, так і вистави зі складними хитросплетеними сюжетами драматичного змісту у складі мімічного ансамблю.

Основна увага приділяється специфіці творчого процесу та творення сценічного образу артиста-міма. Під поняттям «сценічний образ артиста-міма» автори розуміють узагальнений та максимально конкретизований зовнішній вияв внутрішньої сутності, характеру персонажа, його внутрішнього «Я», що знаходяться у невід’ємному зв’язку й цілісній єдності одне з одним і транслюють те, що хоче донести артист до глядача. Підкреслено, що сценічний образ артист пантоміми відтворює завдяки пластичній виразності свого тіла, передачі характеру рухів у позі, змістових жестів та емоційної міміки, через інтеграцію компетенцій драматичного й комедійного актора, хореографічні й імпровізаційні вміння, відповідно до жанрово-стильових ознак цього виду мистецтва. Зазначено, що фестивалі пaнтоміми стали плaтфoрмoю для дiaлoгу мiж різними жанрaми сценiчного мистецтвa, а розмаїття форм дозволяє артистам-мімам експериментувати та освоювати не лише традиційний сценічний простір, а й нові, нестандартні й несподівані тимчасові майданчики, завдяки чому пантоміма сьогодні стає більш доступною та наближеною для широкого кола глядачів, має надзвичайно широкі можливості для свого розвитку.

Published: April 2023

Метою статті є висвітлення специфічних рис роботи звукорежисера циркового мистецтва, характеристика звукорежисерських практик у цирковій роботі, аналіз акустичних властивостей циркового приміщення, вивчення і визначення існуючих проблем і методи їх вирішення на основі сучасних звукотехнічних інновацій і власного звукорежисерського й педагогічного досвіду. Методологія дослідження ґрунтується на філософсько-естетичних засадах музично-звукових концепцій циркового дійства й осмислення музично-комунікативного процесу, що дозволяє підбити підсумки й обґрунтувати висновки окресленої проблематики. Висвітлюючи звукорежисуру в цирковому мистецтві як один зі специфічних і найпізніших напрямків у загальній звукорежисурі, можна окреслити певні вимоги до людей, які займаються цією професією. Вони повинні: професійно оперувати наявною звукотехнікою; доцільно володіти усіма технічними засобами художньої виразності, які застосовуються для звукового оформлення циркових номерів; добре знати акустичні властивості глядацької зали цирку; уміти запобігти та за потреби вчасно усунути виниклі шуми та спотворення у вигляді різного ступеня відлуння, ранніх багаторазових віддзеркалень та ін. 

Робота звукорежисера цирку потребує належного, прискіпливого й критичного ставлення до неї на усіх етапах підготовки нового творчого номера. Йому необхідно спиратись на сучасні цифрові технології та інноваційні звукотехнічні засоби, а вони, у свою чергу, передбачають базис практичної роботи й технічні знання. Звукорежисер, який працює для арени, не може бути тільки технічним працівником, він мусить володіти музично-естетичним смаком, розуміти психологію поведінки тварин і птахів на манежі, уміти знаходити спільну мову з артистами й поважати їхню працю.

Published: April 2023

Aims: Kyphoplasty (KP) surgeries are commonly performed under local, general and regional anesthesia. The purpose of our study was to compare the perioperative and postoperative effects of ultrasound (USG) guided erector spinae plane blocks (ESPB) and paravertebral blocks (PVB) in patients with KP. Methods: Forty patients who underwent kyphoplasty were evaluated retrospective as Group 1 (ESPB, n=20) and Group 2 (PVB,n=20). Perioperative additional opioid, hemodynamic parameters, complications, postoperative analgesia requirement, pain with visual analog scale (VAS) at specified times, amount of analgesic used within 24 hours, first mobilization and discharge time, and complications were compared. Results: There was no difference between the study groups regarding demographic data, ASA, preoperative analgesic use, mean arterial pressure (MAP), heart rate (HR), SpO2, additional opioid requirement, perioperative complication rates, VAS and surgical level. A significant difference was observed between Group 1 and Group 2 regarding the VAS score and paracetamol dose at 6 hours postoperatively (p:0.023 and p:0.006, respectively). There was no statistical difference between the groups first mobilization and discharge time, postoperative complications, postoperative intensive care needs (PICU), and tramadol dose rates used (p>0.05). Conclusion: The USG-guided ESPB and PVB did not appear superior to one another in kyphoplasty procedures regarding 12 and 24-hour VAS scores, first mobilization and discharge time, postoperative complications, PICU needs and tramadol dose. The analgesic effect of ESPB in KP surgery was superior to that of PVB, 6hours postoperatively. Therefore, it is possible to consider them a safe and alternative method of anesthesia and analgesia.

Authors: Endraputra Pristiawan Navy , Kuntaman  , Khoendori Eko Budi
Published: April 2023

Background: Nosocomial infection is derived from the patient itself or transmitted across patients, healthcare workers, or the hospital environment. Carbapenem-resistant Acinetobacter baumannii (CRAB) and Pseudomonas aeruginosa (CRPA) have been recognized as the most common pathogen for nosocomial infections in Southeast Asia. Afterward, CRAB and CRPA infections increase morbidity, mortality, length of stay, and cost. This study examined the prevalence of CRAB and CRPA at Dr. Soetomo Hospital, Surabaya, from January to June 2020.
Methods: This descriptive study was conducted retrospectively by collecting data from the first isolate per specimen per patient of Acinetobacter baumannii and Pseudomonas aeruginosa, resistant either to meropenem or imipenem from urine, blood, pus, or sputum in Dr. Soetomo Hospital, Surabaya within January to June 2020.
Results: A total of 311 Acinetobacter baumannii and 425 Pseudomonas aeruginosa were collected with 134 CRAB and 79 CRPA. The resistance rate of CRAB was ≥90% except for amikacin, cefoperazone-sulbactam, levofloxacin, tigecycline, trimethoprim-sulfamethoxazole, and fosfomycin. Moreover, CRPA had resistance ≥90% regardless of intrinsic resistance against imipenem and colistin. There was an increase in CRAB and CRPA, with the highest incidence in June 2020 in early 2020.
Conclusion: The prevalence of CRAB and CRPA were 43% and 19%, respectively, in the early six months of 2020 at Dr. Soetomo Hospital, Surabaya.

Authors: Fahman Aulia Novariza , Nusjirwan Rama , Maryani Euis , Laksmono Navy
Published: April 2023

Background: Traumatic diaphragmatic rupture (TDR) is a life-threatening condition due to the herniation of abdominal organs into pleural cavities. Rupture can occur in patients with major blunt or penetration trauma of the lower chest. Blunt TDR is usually caused by momentary high energy damage and is associated with severe trauma. This study aims to evaluate our hospital's experience with managing patients with blunt TDR, including its incidence, modes of diagnosis, operative treatments, postoperative outcomes, and factors predictive of patient outcomes.
Case Report: A 44 years old man was referred to our hospital complaining of dyspnea. Eleven hours before his admission, he was riding his motorcycle, fell to the road, and hit the tree on his left chest. After the accident, he feels dyspnea, chest pain, and abdominal pain. The patient was brought to the nearest hospital and underwent a chest x-ray and left chest tube insertion, with initial production was blood 1700 ml. On examination, there was an increased respiratory rate, a visible bruise of the posteroinferior left chest near the left flank and a pre-installed chest tube thoracostomy on the left chest. Chest x-ray showed an intrathoracic herniation of abdominal viscera, the "collar sign" appeared, and the abdomen x-ray showed the left upper quadrant abdominal organ displaced into the left thorax cavity. Thus suspected, the underlying condition of TDR in this patient. We decided to perform left anterolateral thoracotomy and continued with laparotomy and splenectomy
Conclusion: TDR is a rare case. The trauma may include shearing a stretched diaphragm, avulsion from a muscular insertion point, or increased abdominal pressure exceeding the bursting pressure of the diaphragm. Intra-abdominal organ injuries are more common than intrathoracic injuries. Initial operative approaches were laparotomy and thoracotomy.

Authors: Suryadi Taufik , Kulsum
Published: April 2023

Background: Blunt violence on the head often occurs in the community, which often causes fatal conditions and even death. Death due to blunt force on the head can be caused by intracranial bleeding or destruction of brain tissue.
Case description: A case of suspected murder was reported due to blunt violence on the victim's head with the initials RA, 16 years old, a student at an official school. On forensic medical examination found signs of blunt violence in the form of bruises on the forehead and face, and the results of an autopsy found the destruction of the bones forming the face, fracture of the skull with the release of brain tissue. In the police investigation, the suspect admitted to committing violence with a kick on the head of the victim using shoes without other tools. There was a mismatch between the strength of the violence recognized by the suspect and the autopsy findings so that the forensic examination focused on seeing whether blunt violence that occurred on the victim could result in death or not.
Conclusion: It is necessary to deepen police checks on suspects about how violence was carried out, how the power of violence was carried out, and what were the motives for violence. During the trial, the panel of judges stated that there was a possibility that the perpetrators would use hard objects to attack the victim.

Published: April 2023

Introduction: Platelet rich plasma (PRP) contains not only several growth factors but also proinflammatory cytokines that promote the healing process of tendon ruptures. Therefore, this study aimed to determine the effect of PRP administration on TGF- β1 expression during the healing process of Achilles tendon rupture in white rats (Rattus norvegicus).
Method: This study was an experimental research with a Posttest-Only Control Group Design approach. This study enrolled 30 male white rats with a ruptured Achilles tendon, aged 3-4 months and weighing 200-250 grams.  The rats were randomly divided into 2 groups. The first (I) group as the control group included rats with Achilles tendon rupture without PRP administration, and group II as the experimental group included rats with Achilles tendon rupture with PRP 100 ul administration. Equal number of white rats from both groups were observed in 3 different times (on the day 7th, 14th, and 21st) after intervention. Part of the substance of the right Achilles tendon of each white rat was taken for examination of TGF-β1 expression by immunohistochemical examination with anti-TGF- β1 primary antibody. The data were analyzed by using SPSS 25.0. The descriptive data were provided in table, and the analytic data were analyzed by using unpaired t-test. The significant p value was <0.05.
Results: We established that the intensity of TGF- β1 expression of Achilles tendon in the experimental group (with PRP administration) was statistically significant (P<0.05) compared to the control group. TGF- β1 expression in the experimental group established stronger and more extensive staining at weeks 1 and 2 (P < 0.05), while the control group established more extensive staining at week 3 (P < 0,05).
Conclusion: PRP administration can increase TGF-β1 expression during the healing process of Achilles tendon rupture in white rats (Rattus norvegicus) and its statistically significant.
Herpes Zoster on a bladder cancer patient – a rare case
Authors: Widasmara Dhelya , Sitaresmi Adya , Basuki Santosa , Daryanto Besut , Seputra Kurnia Penta
Published: April 2023

Introduction: Herpes zoster (HZ) is caused by reactivation of latent varicella-zoster virus (VZV) infection due to disturbance in T-cell mediated immunity. Risk factors include malignancy and therapy related to malignancy. Bladder cancer has a moderate association with HZ, with a risk increment of 10-50%. The rate of HZ in bladder cancer patients is 8/1000.
Case description: A 57-years-old man with bladder cancer T4bN3M0 complained of a painful erythematous vesicular rash on the left front abdomen extended to the back 1 week prior, accompanied by fever and burning sensation. He has had regular chemotherapy using Gemcitabine and Cisplatin, and radiotherapy with 2 Gray doses each session. Dermatological examination showed multiple well-defined erythematous-based vesicles, clustered on the left abdominal, flank, and posterior thorax region at T7-T9 dermatome. Tzanck-smear examination showed multinucleated giant cells. The patient was given acyclovir, paracetamol, and wet dressing on vesicles. His chemoradiotherapy was also halted. On the 7th day of evaluation, there were no new lesions and his complaints improved.
In cancer patients, CD4+ and CD8+ levels decreased, accompanied by lymphocyte proliferation impairment. Cytotoxic chemotherapy agents work by attacking proliferation cells, affecting immune-related cells. Ion radiation in radiotherapy interferes with a regional cellular immune response that inhibits viral reactivation.
Conclusion: Principal HZ management in cancer patients includes antiviral and analgesics. In cancer patients, the occurrence of HZ can disturb and postpone management related to malignancy. The postponement of chemoradiotherapy is based on the patient's conditions and the severity of the disease.

Méthodes d’assimilation des observations : application aux prévisions météorologiques
Authors: TALAGRAND Olivier
Published: April 2023

L’assimilation des observations météorologiques combine les observations avec un modèle numérique décrivant l’évolution de l’écoulement. Deux classes d’algorithmes, extensions heuristiques de principes linéaires et gaussiens à des situations faiblement non-linéaires et non-gaussiennes, sont utilisées dans la pratique météorologique : le filtre de Kalman d’ensemble et l’assimilation variationnelle. Les filtres particulaires, plus généraux dans leur principe, font l’objet de recherches actives.

Published: April 2023

Le comportement des feux de forêt à grande échelle est largement modélisé comme un problème de propagation du front de feu, où la principale grandeur physique d'intérêt est la vitesse de propagation du front de feu. Cette dernière est partiellement connue lors d'un incendie en raison des incertitudes des paramètres de combustible et des interactions feu/atmosphère induisant des erreurs de position du front de feu dans les prédictions du modèle. Ce chapitre présente un aperçu des approches d'assimilation de données infrarouges thermiques proposées dans la littérature et les perspectives pour la prévision et/ou la réanalyse du comportement des feux de forêt.

Abstract. As peatlands are a major terrestrial sink in the global carbon cycle, gaining understanding of their development and changes throughout time is essential to predict their future carbon budget and potentially mitigate negative influences of climate change. With this aim to understand peat development, many studies have investigated the paleoecological dynamics through the analysis of various proxies, including pollen, macrofossil, elemental, and biomarker analyses. However, as each of these proxies are known to have their own benefits and limitations, examining them in parallel potentially allows for a deeper understanding of these paleoecological dynamics at the peatland and for a systematic comparison of the power of these individual proxies. In this study, we therefore analyzed soil cores from a peatland in Germany (Beerberg, Thuringia) to a) characterize the vegetation dynamics over the course of the peatland development during the late Holocene and b) evaluate to what extent the inclusion of multiple proxies, specifically pollen, macrofossil, and biomarkers, contributes to a deeper understanding of those dynamics and interaction among factors. We found that, despite a major shift in regional forest composition from primarily beech to spruce as well as many indicators of human impact in the region, the local plant population in the Beerberg area remained stable over time following the initial phase of peatland development up until the last couple of centuries. Therefore, little variation could be derived from the paleobotanical data alone. The combination of pollen and macrofossil analyses with the elemental and biomarker analyses enabled further understanding of the site development as these proxies added valuable additional information including the occurrence of climatic variations, such as the Little Ice Age, and more recent disturbances such as drainage and dust deposition.
Chemical abrasion: the mechanics of zircon dissolution
Authors: McKanna Alyssa J. , Koran Isabel , Schoene Blair , Ketcham Richard A.
Published: April 2023

Abstract. Chemical abrasion is a technique that combines thermal annealing and partial
dissolution in hydrofluoric acid (HF) to selectively remove
radiation-damaged portions of zircon crystals prior to U–Pb isotopic
analysis, and it is applied ubiquitously to zircon prior to U–Pb isotope
dilution thermal ionization mass spectrometry (ID-TIMS). The mechanics of
zircon dissolution in HF and the impact of different leaching conditions on
the zircon structure, however, are poorly resolved. We present a
microstructural investigation that integrates microscale X-ray computed
tomography (µCT), scanning electron microscopy, and Raman
spectroscopy to evaluate zircon dissolution in HF. We show that µCT
is an effective tool for imaging metamictization and complex dissolution
networks in three dimensions. Acid frequently reaches crystal interiors via
fractures spatially associated with radiation damage zoning and inclusions
to dissolve soluble high-U zones, some inclusions, and material around
fractures, leaving behind a more crystalline zircon residue. Other acid paths
to crystal cores include the dissolution of surface-reaching inclusions and
the percolation of acid across zones with high defect densities. In highly
crystalline samples dissolution is crystallographically controlled with
dissolution proceeding almost exclusively along the c axis. Increasing the
leaching temperature from 180 to 210 ∘C results in
deeper etching textures, wider acid paths, more complex internal dissolution
networks, and greater volume losses. How a grain dissolves strongly depends
on its initial radiation damage content and defect distribution as well as
the size and position of inclusions. As such, the effectiveness of any
chemical abrasion protocol for ID-TIMS U–Pb geochronology is likely
sample-dependent. We also briefly discuss the implications of our findings
for deep-time (U-Th)/He thermochronology.
Evaluation of the Opinions of the Parents with Disabled and Healthy Children about Third Hand Smoke
Authors: Köksoy Serkan , Can Belkıs
Published: April 2023

Objective: The objectives of this study were to assess the opinions of parents with disabled children (PDC) and parents with healthy children (PHC) about thirdhand smoke (THS).
Method: This study was designed as a cross-sectional study. Study data were collected from the province of Burdur between October and November 2022. Data collection form consists of sociodemographic form, Beliefs about Thirdhand Smoke Scale (BATHS) and Fagerström Test for Nicotine Dependence (FTND).
Results: Totally 365 (100%) people participated in the study, 99 (27.1%) of which were PDC and 266 (72.9%) of which were PHC. A statistical difference was found between the BATHS health and BATHS persistence means of PDC and PHC. The existence of rules about not smoking in the environment they live in was in a way that there is a rule for 62 (63%) people, partially there is a rule for 10 (10%) people and no rule for 27 (27%) people for the PDC. For the PHC, it was 138 (51.9%), 43 (16.2%), and 85 (31.9%) (respectively).
Conclusion: The means of BATHS health and BATHS persistence in PDC were lower than the mean of PHC. In the whole population; BATHS (including its sub-dimensions) scores were associated with participants' economic and educational status. More than half of the population had rules prohibiting tobacco use in their residence. The existence of these rules was higher in PDC. In particular, the opinions of the PDC on THS should be intervened with basic public health approaches and they should be provided with sufficient information on the subject.
Percepciones, reflexiones y aprendizajes de estudiantes de Medicina sobre una experiencia de educación basada en la comunidad de tres años.
Authors: Granero Mariano , Rousseau Portalis Juan C. , Mercadal María A. , Gonzalez Candela V. L.
Published: April 2023

Introducción: La Educación Basada en la Comunidad (EBC) representa una estrategia educativa que acerca la formación médica a la práctica real, y promueve una atención médica de mayor aceptabilidad que contempla la esfera social de los procesos de salud/enfermedad y aborda de forma adecuada las necesidades reales de la población.
Existen, a la fecha, escasas publicaciones a nivel regional en las cuales los propios estudiantes reflexionen sobre este tipo de experiencias formativas. 
Objetivos: Identificar y comunicar los principales aprendizajes obtenidos de una experiencia de EBC por parte de estudiantes de grado de Medicina.
Metodología: Se revisaron las sistematizaciones de experiencias confeccionadas por la primera cohorte que completó esta experiencia en el Instituto Universitario del Hospital Italiano de Buenos Aires. Se reflexionó sobre las principales dificultades observadas y los aprendizajes más significativos obtenidos a partir de dicha experiencia. Se establecieron dominios y codificaron los textos de las sistematizaciones generadas durante la cursada. Finalmente, se generó un mapa de conceptos a partir del cual se escribió este artículo. 
Resultados: Esta experiencia tuvo para los estudiantes tres momentos bien definidos: una etapa inicial, caracterizada por incertidumbre y malestar; una intermedia, con aprendizaje estratégico y algo de transformación; y una avanzada, con aprendizaje profundo y situado.
Conclusión: Es recomendable que a las experiencias de EBC se les asigne el tiempo suficiente en las planificaciones y que finalicen con un proceso de reflexión promovido por el equipo docente.

Authors: De Masi Noelia S. , Rochina Esteban C. , Schpilberg Mónica G. , Puga María C. , Garfi Leonardo G.
Published: April 2023

Introducción: El NPS (Net Promoter Score) es un indicador que se utiliza en los programas de experiencia del cliente para medir la satisfacción de dicho público objetivo y su lealtad. Nuestra finalidad fue consolidar el NPS por primera vez en una prepaga de un hospital de alta complejidad de Buenos Aires (PS-HIBA) en busca de establecer un indicador objetivo desde la perspectiva del cliente.

Métodos: Se realizó un estudio observacional analítico, de corte transversal.  Se incluyeron en el estudio los datos obtenidos a partir de las respuestas de los afiliados al PS-HIBA.

Resultados: Se consolidó el primer indicador NPS del PS-HIBA: 22 puntos. Se visualizaron los tres perfiles de clientes, obteniendo un 45,7% promotores, 22,3% detractores y 32% pasivos o neutros. Complementariamente se identificaron los motivos de dichas calificaciones; las tres principales fueron: la problemática de accesibilidad a los turnos, la atención y los profesionales valorados positivamente.

Conclusión: Este estudio aporta un indicador objetivo, que facilita un lenguaje común en la organización y una comparación con el mercado desde la mirada del cliente.

El NPS, como sistema, busca impulsar la construcción de una cultura centrada en el cliente, con el fin de mejorar su lealtad y permitir una retroalimentación donde se logra tener presente la voz del cliente, e identificar, priorizar y abordar los problemas percibidos. Nos permite establecer los lineamientos de oportunidades de mejora desde la perspectiva de los pacientes.
