Comparative effectiveness of gemcitabine plus cisplatin versus methotrexate, vinblastine, doxorubicin, plus cisplatin as neoadjuvant therapy for muscle-invasive bladder cancer.

BACKGROUND: Gemcitabine plus cisplatin (GC) has been adopted as a neoadjuvant regimen for muscle-invasive bladder cancer despite the lack of Level I evidence in this setting. METHODS: Data were collected using an electronic data-capture platform from 28 international centers. Eligible patients had clinical T-classification 2 (cT2) through cT4aN0M0 urothelial cancer of the bladder and received neoadjuvant GC or methotrexate, vinblastine, doxorubicin, plus cisplatin (MVAC) before undergoing cystectomy. Logistic regression was used to compute propensity scores as the predicted probabilities of patients being assigned to MVAC versus GC given their baseline characteristics. These propensity scores were then included in a new logistic regression model to estimate an adjusted odds ratio comparing the odds of attaining a pathologic complete response (pCR) between patients who received MVAC and those who received GC. RESULTS: In total, 212 patients (146 patients in the GC cohort and 66 patients in the MVAC cohort) met criteria for inclusion in the analysis. The majority of patients in the MVAC cohort (77%) received dose-dense MVAC. The median age of patients was 63 years, they were predominantly men (74%), and they received a median of 3 cycles of neoadjuvant chemotherapy. The pCR rate was 29% in the MVAC cohort and 31% in the GC cohort. There was no significant difference in the pCR rate when adjusted for propensity scores between the 2 regimens (odds ratio, 0.91; 95% confidence interval, 0.48-1.72; P = .77). In an exploratory analysis evaluating survival, the hazard ratio comparing hazard rates for MVAC versus GC adjusted for propensity scores was not statistically significant (hazard ratio, 0.78; 95% confidence interval, 0.40-1.54; P = .48). CONCLUSIONS: Patients who received neoadjuvant GC and MVAC achieved comparable pCR rates in the current analysis, providing evidence to support what has become routine practice.

A new multidisciplinary home care telemedicine system to monitor stable chronic human immunodeficiency virus-infected patients: a randomized study.

Background: Antiretroviral therapy has changed the natural history of human immunodeficiency virus (HIV) infection in developed countries, where it has become a chronic disease. This clinical scenario requires a new approach to simplify follow-up appointments and facilitate access to healthcare professionals. Methodology: We developed a new internet-based home care model covering the entire management of chronic HIV-infected patients. This was called Virtual Hospital. We report the results of a prospective randomised study performed over two years, comparing standard care received by HIV-infected patients with Virtual Hospital care. HIV-infected patients with access to a computer and broadband were randomised to be monitored either through Virtual Hospital (Arm I) or through standard care at the day hospital (Arm II). After one year of follow up, patients switched their care to the other arm. Virtual Hospital offered four main services: Virtual Consultations, Telepharmacy, Virtual Library and Virtual Community. A technical and clinical evaluation of Virtual Hospital was carried out. Findings: Of the 83 randomised patients, 42 were monitored during the first year through Virtual Hospital (Arm I) and 41 through standard care (Arm II). Baseline characteristics of patients were similar in the two arms. The level of technical satisfaction with the virtual system was high: 85% of patients considered that Virtual Hospital improved their access to clinical data and they felt comfortable with the videoconference system. Neither clinical parameters [level of CD4 + T lymphocytes, proportion of patients with an undetectable level of viral load (p = 0.21) and compliance levels 90% (p = 0.58)] nor the evaluation of quality of life or psychological questionnaires changed significantly between the two types of care. Conclusions: Virtual Hospital is a feasible and safe tool for the multidisciplinary home care of chronic HIV patients. Telemedicine should be considered as an appropriate support service for the management of chronic HIV infection.

Impact of geographical and cultural factors on clinical trials in acute mania: lessons from a ziprasidone and haloperidol placebo-controlled study

Clinical trials today are conducted in multiple countries to enhance patient recruitment and improve efficiency of trials. However, the demographic and cultural diversity may contribute to variations in study outcomes. Here we conducted post-hoc analyses for a placebo-controlled study with ziprasidone and haloperidol for the treatment of acute mania to address the demographic, dosing, and outcome disparities in India, Russia and the USA. We compared the baseline characteristics, outcomes and discontinuations in patients and explored the relationship between the outcome measures across these countries. We found substantial differences in baseline characteristics of subjects, administered dosage and disease severity in India compared to the USA and Russia. Conversely, US subjects had a higher placebo response compared to subjects in Russia and India. These results are probably due to demographic differences in patient populations and psychiatric clinical practice across countries. While we offer initial ideas to address the disparities identified in this analysis, it is clear that further research to improve our understanding of geographical differences is essential to ensure globally applicable results for clinical trials in psychiatry.

Drug-eluting stents compared to bare-metal stents improve short-term survival in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention: a nationwide prospective analysis of the AMIS Plus registry.

BACKGROUND: Recently, it has been suggested that the type of stent used in primary percutaneous coronary interventions (pPCI) might impact upon the outcomes of patients with acute myocardial infarction (AMI). Indeed, drug-eluting stents (DES) reduce neointimal hyperplasia compared to bare-metal stents (BMS). Moreover, the later generation DES, due to its biocompatible polymer coatings and stent design, allows for greater deliverability, improved endothelial healing and therefore less restenosis and thrombus generation. However, data on the safety and performance of DES in large cohorts of AMI is still limited. AIM: To compare the early outcome of DES vs. BMS in AMI patients. METHODS: This was a prospective, multicentre analysis containing patients from 64 hospitals in Switzerland with AMI undergoing pPCI between 2005 and 2013. The primary endpoint was in-hospital all-cause death, whereas the secondary endpoint included a composite measure of major adverse cardiac and cerebrovascular events (MACCE) of death, reinfarction, and cerebrovascular event. RESULTS: Of 20,464 patients with a primary diagnosis of AMI and enrolled to the AMIS Plus registry, 15,026 were referred for pPCI and 13,442 received stent implantation. 10,094 patients were implanted with DES and 2,260 with BMS. The overall in-hospital mortality was significantly lower in patients with DES compared to those with BMS implantation (2.6% vs. 7.1%,p < 0.001). The overall in-hospital MACCE after DES was similarly lower compared to BMS (3.5% vs. 7.6%, p < 0.001). After adjusting for all confounding covariables, DES remained an independent predictor for lower in-hospital mortality (OR 0.51,95% CI 0.40-0.67, p < 0.001). Since groups differed as regards to baseline characteristics and pharmacological treatment, we performed a propensity score matching (PSM) to limit potential biases. Even after the PSM, DES implantation remained independently associated with a reduced risk of in-hospital mortality (adjusted OR 0.54, 95% CI 0.39-0.76, p < 0.001). CONCLUSIONS: In unselected patients from a nationwide, real-world cohort, we found DES, compared to BMS, was associated with lower in-hospital mortality and MACCE. The identification of optimal treatment strategies of patients with AMI needs further randomised evaluation; however, our findings suggest a potential benefit with DES.

Outcome of patients admitted with acute coronary syndrome on palliative treatment: insights from the nationwide AMIS Plus Registry 1997-2014.

OBJECTIVE: Compliance with guidelines is increasingly used to benchmark the quality of hospital care, however, very little is known on patients admitted with acute coronary syndromes (ACS) and treated palliatively. This study aimed to evaluate the baseline characteristics and outcomes of these patients. DESIGN: Prospective cohort study. SETTING: Eighty-two Swiss hospitals enrolled patients from 1997 to 2014. PARTICIPANTS: All patients with ACS enrolled in the AMIS Plus registry (n=45,091) were analysed according to three treatment groups: palliative treatment, defined as use of aspirin and analgesics only and no reperfusion; conservative treatment, defined as any treatment including antithrombotics or anticoagulants, heparins, P2Y12 inhibitors, GPIIb/IIIa but no pharmacological or mechanical reperfusion; and reperfusion treatment (thrombolysis and/or percutaneous coronary intervention during initial hospitalisation). The primary outcome measure was in-hospital mortality and the secondary measure was 1-year mortality. RESULTS: Of the patients, 1485 (3.3%) were palliatively treated, 11,119 (24.7%) were conservatively treated and 32,487 (72.0%) underwent reperfusion therapy. In 1997, 6% of all patients were treated palliatively and this continuously decreased to 2% in 2013. Baseline characteristics of palliative patients differed in comparison with conservatively treated and reperfusion patients in age, gender and comorbidities (all p<0.001). These patients had more in-hospital complications such as postadmission onset of cardiogenic shock (15.6% vs 5.2%; p<0.001), stroke (1.8% vs 0.8%; p=0.001) and a higher in-hospital mortality (25.8% vs 5.6%; p<0.001).The subgroup of patients followed 1 year after discharge (n=8316) had a higher rate of reinfarction (9.2% vs 3.4%; p=0.003) and mortality (14.0% vs 3.5%; p<0.001). CONCLUSIONS: Patients with ACS treated palliatively were older, sicker, with more heart failure at admission and very high in-hospital mortality. While refraining from more active therapy may often constitute the most humane and appropriate approach, we think it is important to also evaluate these patients and include them in registries and outcome evaluations.

Belgian experience with triple therapy with boceprevir and telaprevir in genotype 1 infected patients who inject drugs.

No data have been reported yet on treatment outcome in persons who inject drugs (PWID) infected with hepatitis C virus treated with boceprevir or telaprevir in combination with peginterferon (Peg IFN) and ribavirin (RBV). Additionally, there are concerns about the safety of boceprevir and telaprevir in some subgroups of patients with hepatitis C (HCV). In a cohort of HCV patients infected with genotype 1 in Belgium, treatment outcome of patients infected due to IV drug use was analyzed and compared with patients who have no history of substance use. The study population consisted of 179 patients: 78 PWID and 101 controls treated with boceprevir (n = 79) or telaprevir (n = 100) additional to Peg IFN and RBV; 53 (30%) had advanced disease (F3, F4) and 79 (44%) had an antiviral therapy previously. There were no significant differences in the baseline characteristics between both groups, except that PWID patients were more frequently infected with genotype 1a (67% vs 21%), were younger and were predominantly male. Psychiatric complaints during follow-up occurred more frequently in the PWID patients: 24% versus 11% (P = .02). Treatment failure for other reasons than absence of viral response was 70% and 64% in PWID and non-PWID respectively. The sustained viral response (SVR) rates were similar in both groups (71% in PWID vs 72% in non-PWID); with a non-inferiority test with -5% margin there is a difference of -1% (95% CI [-15%, 13%]) and P = 0.30. There are no reasons to exclude PWID from treatment with boceprevir, telaprevir and novel antiviral therapies. J. Med. Virol. 88:94-99, 2016. © 2015 Wiley Periodicals, Inc.

The impact of an enhanced recovery pathway on nursing workload: A retrospective cohort study.

BACKGROUND & AIMS: The importance of nursing for surgical patients has been frequently underestimated. The success of enhanced recovery programs after surgery (ERAS) depends on preferably complete fulfilment of the protocol and nurses are an important part of it. Due to the additional nursing action required, such protocols are suspected to increase the nursing workload. The aim of the present study was to observe and measure objectively nursing workload before, during and after systematic implementation of a comprehensive enhanced recovery pathway in colorectal surgery. METHODS: The program ERAS was introduced systematically in our tertiary academic centre 2011, since then our experience is based on more than 1500 ERAS patients. Nursing workload was prospectively assessed for all patients on a routine basis by means of a standardized and validated point system (PRN). In a retrospective cohort study, we compared nursing workload based on prospective data before, during and after ERAS implementation and correlated nursing workload to the compliance with the ERAS protocol. RESULTS: The study cohort included 50 patients before ERAS implementation (2010) and 69 (2011) and 148 (2012) consecutive patients after implementation; the baseline characteristics of the 3 groups were similar. Mean PRN values were 61.2 ± 19.7 per day in 2010 and decreased to 52.3 ± 13.7 (P = 0.005) and 51.6 ± 18.6 (P < 0.002) in 2011 and 2012, respectively. Increasing compliance with the ERAS protocol was significantly correlated to decreasing nursing workload (ρ = -0.42; P < 0.001). CONCLUSIONS: Nursing workload is - against a common belief - decreased by systematic implementation of enhance recovery protocol. The higher the compliance with the pathway, the lower the burden for the nurses!

CONVERSION TO AFLIBERCEPT THERAPY VERSUS CONTINUING WITH RANIBIZUMAB THERAPY FOR NEOVASCULAR AGE-RELATED MACULAR DEGENERATION DEPENDENT ON MONTHLY RANIBIZUMAB TREATMENT.

PURPOSE: To compare the effects of converting to aflibercept therapy with continuing ranibizumab therapy in eyes with neovascular age-related macular degeneration requiring monthly ranibizumab treatment. METHODS: Patients were selected from the 104 patients (115 eyes) already enrolled in an "Observe and Plan" prospective case series that included treating neovascular age-related macular degeneration with ranibizumab for 24 months. Patients who still needed monthly retreatment at the end of a 2-year study were randomized to either continue ranibizumab therapy or to convert to aflibercept therapy. Outcome measures included average interval between treatments, resolution of exudative signs, number of retreatments, and change in visual acuity over 12 months (the third treatment year). RESULTS: Nineteen patients (21 eyes) met the inclusion criteria. Ten eyes were randomized to receive aflibercept, and 11 eyes remained on ranibizumab. Groups were balanced for baseline characteristics. Outcomes were similar in the 2 groups over a 12-month study duration, with no statistical difference. CONCLUSION: This comparative pilot study suggests that neovascular age-related macular degeneration requiring monthly retreatment with ranibizumab may respond in similar ways to both ranibizumab and aflibercept treatment. Larger sample sizes would be needed to confirm this observation.

Predictors of psychiatric hospitalization during 6 months of maintenance treatment with olanzapine long-acting injection: post hoc analysis of a randomized, double-blind study.

BACKGROUND: Hospitalization is a costly and distressing event associated with relapse during schizophrenia treatment. No information is available on the predictors of psychiatric hospitalization during maintenance treatment with olanzapine long-acting injection (olanzapine-LAI) or how the risk of hospitalization differs between olanzapine-LAI and oral olanzapine. This study aimed to identify the predictors of psychiatric hospitalization during maintenance treatment with olanzapine-LAI and assessed four parameters: hospitalization prevalence, incidence rate, duration, and the time to first hospitalization. Olanzapine-LAI was also compared with a sub-therapeutic dose of olanzapine-LAI and with oral olanzapine. METHODS: This was a post hoc exploratory analysis of data from a randomized, double-blind study comparing the safety and efficacy of olanzapine-LAI (pooled active depot groups: 405 mg/4 weeks, 300 mg/2 weeks, and 150 mg/2 weeks) with oral olanzapine and sub-therapeutic olanzapine-LAI (45 mg/4 weeks) during 6 months' maintenance treatment of clinically stable schizophrenia outpatients (n=1064). The four psychiatric hospitalization parameters were analyzed for each treatment group. Within the olanzapine-LAI group, patients with and without hospitalization were compared on baseline characteristics. Logistic regression and Cox's proportional hazards models were used to identify the best predictors of hospitalization. Comparisons between the treatment groups employed descriptive statistics, the Kaplan-Meier estimator and Cox's proportional hazards models. RESULTS: Psychiatric hospitalization was best predicted by suicide threats in the 12 months before baseline and by prior hospitalization. Compared with sub-therapeutic olanzapine-LAI, olanzapine-LAI was associated with a significantly lower hospitalization rate (5.2% versus 11.1%, p < 0.01), a lower mean number of hospitalizations (0.1 versus 0.2, p = 0.01), a shorter mean duration of hospitalization (1.5 days versus 2.9 days, p < 0.01), and a similar median time to first hospitalization (35 versus 60 days, p = 0.48). Olanzapine-LAI did not differ significantly from oral olanzapine on the studied hospitalization parameters. CONCLUSIONS: In clinically stable schizophrenia outpatients receiving olanzapine-LAI maintenance treatment, psychiatric hospitalization was best predicted by a history of suicide threats and prior psychiatric hospitalization. Olanzapine-LAI was associated with a significantly lower incidence of psychiatric hospitalization and shorter duration of hospitalization compared with sub-therapeutic olanzapine-LAI. Olanzapine-LAI did not differ significantly from oral olanzapine on hospitalization parameters.

Impact of a 2-year intervention program on cardiometabolic profile according to the number of goals achieved

We investigated the impact of lifestyle goal achievement on cardiovascular risk factors after a 2-year behavioral intervention program applied to 394 adults (113 with diabetes, mean age 60.2 ± 11.4 years, 56% women) and targeting four goals: ≥5% weight loss; ≥150 min/week physical activities; <10% saturated fat intake/day; ≥400 g fruit and vegetable intake/day. Baseline characteristics and changes in variables after intervention among the four categories of number of goals achieved (none, 1, 2, and ≥3) were compared by independent ANOVA or the Kruskal-Wallis test. Individuals without diabetes achieving a higher number of goals were more likely to be older (3 or 4 goals: 61.8 ± 12.6 years vs none: 53.3 ± 10.3 years, P < 0.05) and to have a lower mean BMI (3 or 4 goals: 21.7 ± 2.6 kg/m² vs none: 29.0 ± 4.8 kg/m², P < 0.05), diastolic blood pressure (3 or 4 goals: 77.3 ± 2.1 mmHg vs none: 85.4 ± 9.6 mmHg, P < 0.05), triglyceride (3 or 4 goals: 116.1 ± 95.1 mg/dL vs none: 144.8 ± 65.5 mg/dL, P < 0.05) and insulin levels (3 or 4 goals: 3.6 ± 2.4 μU/L vs none: 5.7 ± 4.0 μU/L, P < 0.05) than those achieving fewer goals. The absolute changes in cardiovascular risk factors tended to be more pronounced with increasing number of goals achieved in individuals without diabetes. The intervention had a beneficial impact on the cardiometabolic profile of individuals with normal or altered glucose metabolism. The number of goals achieved in this lifestyle intervention was associated with the magnitude of improvement of cardiovascular risk factors in individuals without diabetes. Participants with a better cardiometabolic profile seemed to be more likely to have a healthy lifestyle.

Fibrillation auriculaire et insuffisance cardiaque : une analyse de coût comparant la stratégie de contrôle de la fréquence à celle du contrôle du rythme

Contexte : La fibrillation auriculaire est commune chez les insuffisants cardiaques. L’efficacité des stratégies de contrôle de la fréquence et du rythme s’équivalent. Nous avons comparé l’impact économique des deux stratégies de traitement chez les patients avec fibrillation auriculaire et insuffisance cardiaque. Méthode : Dans cette sous-étude de l’essai Atrial Fibrillation and Congestive Heart Failure, la consommation de soins de santé des patients Québécois ainsi que leurs coûts ont été quantifiés grâce aux banques de données de la Régie de l’assurance-maladie du Québec et de l’Ontario Case Costing Initiative. Résultats : Trois cent quatre patients ont été inclus, âgés de 68±9 ans, fraction d’éjection de 26±6%. Les caractéristiques de base étaient bien réparties entre le contrôle du rythme (N=149) et de la fréquence (N=155). Les patients soumis au contrôle de la fréquence ont eu moins de procédures cardiovasculaires (146 versus 238, P<0.001) en raison du plus faible nombre de cardioversions et de moindres coûts reliés aux antiarythmiques (48 $±203 versus 1319 $±1058 par patient, P<0.001). Ces différences ont été compensées par un surplus de dépenses dues aux hospitalisations non-cardiovasculaires, aux dispositifs cardiaques implantables et aux médicaments non-cardiovasculaires dans le groupe du contrôle de la fréquence. Au total, les coûts par patient avec les stratégies du contrôle de la fréquence et du rythme s’élèvent à 78 767 $±79 568 et 72 764 $±72 800 (P=0.49). Interprétation : Chez les patients avec fibrillation auriculaire et insuffisance cardiaque, le contrôle de la fréquence est associé avec moins de procédures cardiovasculaires et une pharmacothérapie cardiovasculaire moins coûteuse. Toutefois, les coûts associés aux arythmies représentent moins de la moitié des dépenses de santé et le total des coûts s’équilibre entre les 2 stratégies.

El efecto de los anti inflamatorios no esteroideos sobre el espesor retiniano, inflamación y agudeza visual posterior a la extracción de catarata: un estudio prospectivo comparando nepafenac y dexametasona

Objetivos: Comparar el volumen macular total (VMT) y espesor retiniano, la agudeza visual mejor corregida (AVCC) y la incidencia de edema macular post cirugía de catarata, en ojos tratados con nepafenac 0.1%, dexametasona 0.1% o la combinación de los dos. Métodos: En una estudio prospectivo, aleatorizado, controlado y ciego para el observador, se aleatorizaron 147 ojos con catarata para recibir dexametasona 0.1% cada 6 horas por 12 días de forma postoperatoria, nepafenac 0.1% cada 8 horas antes de cirugía y por 15 días postoperatorios o la combinación de los dos. Los desenlaces medidos fueron presión intraocular a la primera y sexta semana, AVCC, VMT (medido por OCT), espesor foveal y perifoveal, y la presencia o ausencia de edema macular (espesor foveal > 240 micras, medido por OCT) a las 6 semanas. Resultados: En la primera semana, la presión intraocular fue significativamente mayor en el Grupo de dexametasona (p<0.05), y luego fue similar entre grupos a la sexta semana. No se presentaron diferencias significativas en agudeza visual. El espesor perifoveal fue significativamente menor en el grupo de nepafenac (p<0.05). La incidencia de edema macular medido por OCT fue de 7.5% (11 ojos); de estos 5 pertenecían al grupo dexametasona, tres al Grupo de Nepafenac y 3 ojos al Grupo de la combinación (p>0.05) Conclusión:. Los resultados demuestran que el nepafenac es por lo menos igual de efectivo para evitar la inflamación postoperatoria al compararlo con dexametasona, y adicionalmente podría ser útil para evitar el edema macular post cirugía de catarata.

Comparación de la severidad y extensión de la enfermedad coronaria multivaso por Syntax Score en una poblaciòn de las Antillas Holandesas vs controles nacionales

En la Enfermedad Coronaria (EC) existen factores genéticos, socioculturales, medioambientales y raciales adicionales a los factores de riesgo cardiovascular mayores que podrían influir en su presentación. Se desconoce el impacto de la raza en la severidad de la enfermedad coronaria en los pacientes extranjeros que son enviados a nuestro Servicio. Objetivos: Comparar la severidad de la EC multivaso en una población de pacientes de las Antillas y Nacionales, pareados por la escala Framingham. Metodología: Realizamos un estudio de corte transversal, comparando pacientes colombianos contra pacientes provenientes de las Antillas holandesas con similares factores de riesgo según escala de Framingham, catalogándolos por grupos de riesgo bajo, intermedio, alto y muy alto. Todos con EC severa multivaso documentada por angiografía coronaria desde enero del 2009 hasta Junio de 2011. Se excluyeron pacientes con antecedentes de intervención percutánea o quirúrgica previa. Resultados: Ingresaron 115 pacientes internacionales y 115 pacientes nacionales. La relación hombres/mujeres 3:1. La proporción de grupos de riesgo fue de bajo riesgo 2.5%, intermedio 15%, alto 19.3%, y muy alto 63.4%. El Syntax Score en pacientes nacionales fue 14.3+/-7.4 y en internacionales 22.2+/-10.5 p: 0.002. Conclusiones: En pacientes provenientes de las Antillas Holandesas, valorados en nuestra institución, se observó una mayor severidad de la enfermedad coronaria comparada con una población nacional con factores de riesgo similares. Estos hallazgos sugieren la influencia de la raza y factores genéticos en la severidad y extensión de la EC

Complicaciones postoperatorias tempranas de la colporrafia anterior por técnica tradicional versus técnica de sitio específico

El prolapso del piso pélvico es una entidad frecuente, especialmente en pacientes postmenopáusicas y en su gran mayoría requiere tratamiento quirúrgico. En este estudio comparamos la aparición de complicaciones postoperatorias tempranas entre la colporrafia anterior con técnica clásica (TC) versus la colporrafia anterior con técnica de sitio especifico (CSE). Se realizó un estudio observacional analítico, retrospectivo, de dos cohortes de pacientes que requirieron colporrafia anterior entre agosto de 2009 hasta junio de 2012. Las características de cada grupo fueron homogéneas y comparables. El desenlace de mayor frecuencia fue dehiscencia de la línea de sutura, sin embargo, no se encontraron diferencias estadísticamente significativas entre las dos técnicas. La aparición de reprolapso temprano y el diagnóstico de abscesos o hematomas presentaron frecuencias que carecen de diferencia significativa. No hubo complicaciones tempranas graves tales como sangrado intraoperatoria mayor o lesiones vesicouretrales. Los resultados sugieren que las dos técnicas tienen una incidencia baja de complicaciones postoperatorias tempranas y por lo tanto parecen ser seguros dentro del manejo quirúrgico del prolapso del componente anterior del piso pélvico.

Delirium. Los factores de riesgo propios de los pacientes en la Fundación Cardioinfantil - Instituto de Cardiología. Estudio de casos y controles

Introducción: el delirium es el trastorno neuropsiquiátrico más frecuente entre pacientes hospitalizados, se asocia con aumento en el tiempo de hospitalización, complicaciones nosocomiales e incluso se le atribuye aumento de la mortalidad de forma independiente. Existen estudios acerca de factores de riesgo para la condición, enfocados en las patologías, medicaciones y antecedentes de los pacientes; sin embargo son escasos los que buscan identificar los factores propios de los pacientes y del proceso de hospitalización, el cual es el objetivo del presente. Metodología: se realizó un estudio con diseño de casos y controles, incluyendo pacientes de la Fundación Cardioinfantil - Instituto de Cardiología con diagnóstico de delirium, hospitalizados entre marzo de 2011 y marzo de 2013. Con una muestra calculada de 201 pacientes, 67 casos y 134 controles (2:1), se equiparó los grupos para edad, piso de hospitalización, tipo de habitación hospitalaria y la fecha de hospitalización, obteniendo las variables de interés. Resultados: se encontró distintas variables relacionadas con delirium, algunas de estas clásicamente asociadas con la condición, posterior al análisis de los datos, las variables más fuertemente relacionadas con la condición fueron el tipo de ingreso, escala visual análoga del dolor, índice de Barthel y el tiempo de estancia en urgencias. Discusión: en nuestra revisión, el presente estudio es el primero de nuestro medio que busca identificar los factores de riesgo dados por la condición basal de los pacientes en su ingreso al hospital, estos factores fácilmente identificables son de utilidad para la prevención de la condición.
