Highlights Abstract Background: In pediatric patients, intravenous placement success may be related to predetermined vascular access difficulty. The study purpose was to examine validity and reliability of the 6-item Pediatric Intravenous Difficulty Score. Methods: We determined if a tool that assesses pediatric intravenous difficulty was associated with clinical outcomes of peripheral attempts (criterion validity), hypotheses regarding patients’ age, race, and medical diagnosis (construct validity), and reliability of difficulty levels. Results: In 596 episodes of peripheral intravenous attempts, first-attempt success, overall success, and number of staff attempting access were associated with level of intravenous access difficulty by tool score. The tool met hypothesized construct validity criteria, and in multivariable modeling, the tool was reliable based on difficulty levels of 2 user groups. Conclusions: The 6-item Pediatric Intravenous Difficulty Score has criterion and construct validity and is reliable over time among clinicians with different levels of expertise in peripheral vascular access.

Probabilistic Sample

El presente trabajo reportó el análisis de validez de un instrumento para medir la disposición hacia el estudio en estudiantes de secundaria. Se seleccionó una muestra probabilística de 306 estudiantes de una escuela secundaria pública del sur de México. Los análisis de validez de constructo arrojaron la presencia de cuatro factores que explican el 58.3% de la varianza total del constructo (motivación intrínseca hacia el estudio, compromiso con la tarea, autorregulación y adaptación). Se concluye que el instrumento cuenta con los criterios de validez para justificar la necesidad de otros estudios que fortalezcan sus propiedades psicométricas y para ser usado con precauciones en la medición de la disposición hacia el estudio.AbstractThis paper describes a validity and reliability analysis of an instrument designed to measure disposition of study in secondary school students. A probabilistic sample of 306 students was selected from a secondary public school in southern Mexico. The construct validity analysis showed the presence of four factors explaining 58.3% of total variance. It was concluded that the instrument complies with validity criteria to justify further studies to strengthen its psychometric properties and to be used with care in research regarding study disposition as well.Recibido: 6 de enero de 2010Aceptado: 6 de septiembre de 2010

AbstractThe purpose of this study is to evaluate the effectiveness of SafeBoard, a Food and Drug Administration–approved extremity stabilization device, as an assistive method in performing peripherally inserted central catheter procedures on children 0 to 3 years of age. This is a retrospective chart review (n = 59) of vascular access procedures where SafeBoard was utilized (n = 32) in comparison to those procedures which utilized a traditional approach to placement (n = 27). Statistical analysis demonstrated significant effect on length of procedure time, number of personnel needed for procedure, and success of placement when SafeBoard was utilized. Obtaining vascular access in pediatrics can be a challenging endeavor. Most young pediatric patients require procedural sedation and/or assistive personnel as a “holder” for successful vascular access placement to occur. An alternative option for extremity stabilization may provide improved workflow and improved placement success, which in turn may positively affect workflow.

AbstractTherapeutic plasma exchange (TPE) is a treatment administered with the aim of removing a pathogenic material or compound causing morbidity in a variety of neurologic, hematologic, renal, and autoimmune diseases. In this study, we aimed to assess the indications, efficacy, reliability, complications, and treatment response of pediatric patients for TPE. This retrospective study analyzed data from 39 patients aged from 0 to 18 years who underwent a total of 172 TPE sessions from January 2015 to April 2018 in a tertiary pediatric intensive care unit. Indications for TPE were, in order of frequency, macrophage activation syndrome (28.2%, n = 11), renal transplantation rejection (15.4%, n = 6), liver failure (15.4%, n = 6), Guillain–Barre's syndrome (15%, n = 6), hemolytic uremic syndrome (7.7%, n = 3), acute demyelinating disease (7.7%, n = 3), septic shock (5.1%, n = 2), and intoxication (5.1%, n = 2). No patient had any adverse event related to the TPE during the procedure. The TPE session was ended prematurely in one patient due to insufficient vascular access and lack of blood flow (2.6%). In the long term, thrombosis due to the indwelling central catheter occurred (5.1%, n = 2). TPE appears to be an effective first-stage or supplementary treatment in a variety of diseases, may be safely used in pediatric patients, and there are significant findings that its area of use will increase. In experienced hands and when assessed carefully, it appears that the rate of adverse reactions and vascular access problems may be low enough to be negligible.

This study aimed to develop an instrument for measuring the attitudes that reflect the characteristics of the pandemic (Adult Pandemic Attitude Scale (A-PAS)) and verifying its validity and reliability. This study used a methodological research design and was conducted with a development step and an evaluation step. The development step included development of preliminary items, content validity, face validity, and preliminary investigation. The evaluation step included item analysis, construct validity, convergent validity, discriminant validity, criterion validity, factor naming, reliability, and completion of the final instrument. The A-PAS developed in this study consisted of a total of 20 items in five dimensions. The internal consistency of 20 items of the A-PAS, Cronbach’s α was 0.92 for 20 items, Cronbach’s α for each factor, a subscale of instrument, was 0.61~0.87 and Raykov’s p coefficient of each factor, which is a subscale of the tool, was found to be 0.60 to 0.88. Analysis of construct validity showed the results as follows: χ2 (p) = 134.05 (p < 0.001), RMSEA = 0.02, RMR = 0.02, GFI = 0.94, CFI = 0.99. The study findings suggest that the developed instrument can be utilized to measure the attitudes of adults toward pandemics, and reflect the reality of the pandemic situation. The outcomes can be used as valuable data for intervention, prevention activities, and policy preparation. The instrument will be applied in the event of a pandemic, such as COVID-19, and will be helpful in promoting the health of the people.

AbstractThere is a new emphasis on tailoring appropriate vascular access for hemodialysis to patients and their life-plans, but there is little known about the optimal use of newer devices such as early-cannulation arteriovenous grafts (ecAVG), with studies utilising them in a wide variety of situations. The aim of this study was to determine if the outcome of ecAVG can be predicted by patient characteristics known pre-operatively. This retrospective analysis of 278 consecutive ecAVG with minimum one-year follow-up correlated functional patency with demographic data, renal history, renal replacement and vascular access history. On univariate analysis, aetiology of renal disease, indication for an ecAVG, the number of previous tunnelled central venous catheters (TCVC) prior to insertion of an ecAVG, peripheral vascular disease, and BMI were significant associates with functional patency. On multivariate analysis the number of previous TCVC, the presence of peripheral vascular disease and indication were independently associated with outcome after allowing for age, sex and BMI. When selecting for vascular access, understanding the clinical circumstances such as indication and previous vascular access can identify patients with differing outcomes. Importantly, strategies that result in TCVC exposure have an independent and cumulative association with decreasing long-term patency for subsequent ecAVG. As such, TCVC exposure is best avoided or minimised particularly when ecAVG can be considered.
