Randomized Trial Comparing Instructor-Delivered Feedback with Self-Assessment Using Video During Basic Skills Training

Feedback has been shown to be one of the most powerful and effective influences on student achievement; however, the optimal method for providing feedback to trainees during veterinary skills training has yet to be determined. A prospective mixed-methods study was undertaken to evaluate student perceptions and performance outcomes with self-assessment using video- or instructor-delivered feedback during skills training using a model. Forty participants naïve to intravenous (IV) catheter placement were randomly assigned either to self-assessment using video or to instructor-directed feedback. A questionnaire probing participants’ perceptions of their knowledge level and confidence in their skills was completed before and after the training, and an interview was done at study completion. Final skill performance was recorded using video capture to permit blind evaluations using a standard assessment tool. A quantitative evaluation of the performance and questionnaire scores, as well as a qualitative assessment of the interviews, was performed. Questionnaire scores were significantly higher in the post-study questionnaire for 12 of the 14 questions in both groups. Students assigned to the instructor-directed group had significantly higher scores than students in the self-directed group on the skill performance ( p < .05). Self-reported confidence in knowledge and skill related to the IV catheterization technique improved with both self-directed feedback using video and instructor-directed feedback. Skill performance, however, was superior following instructor-directed feedback. Participants expressed positive experiences associated with use of the models for skills training, the value of the learning materials including the video, and guidance during learning.

Incidence of urinary tract infection in neonates with significant indirect Hyperbilirubinemia of unknown etiology: case-control study

Background Indirect hyperbilirubinemia is frequently encountered during neonatal period. Although it has different causes, in some cases it can’t be explained. Previous studies have illustrated that jaundice could be a major sign of urinary tract infection (UTI) in neonates. Aim of the work We aimed to determine the association between UTI and significant unexplained neonatal indirect hyperbilirubinemia. Methods This prospective controlled study was performed on 150 neonates divided in two groups (100 as cases and 50 as controls) to investigate the incidence of UTI in neonates with significant unexplained hyperbilirubinemia. Urine sample was obtained using urine catheterization technique from neonates and full urine analysis was done and cases with pyuria had urine culture to confirm UTI. Immediate renal ultrasonography (USG) was performed for neonates with UTI. Results UTI incidence was 11% in cases while none of neonates in control group had UTI with statistical significance between cases and controls (P value < 0.05). The most common (36.4%) pathogen was Escherichia coli. Posterior urethral valve with mild hydronephrosis was diagnosed in 18.2% of UTI positive patients by renal ultrasonography. Conclusion In neonates with unexplained indirect hyperbilirubinemia, UTI should be considered as a pathological cause.

INCIDENCE OF URINARY TRACT INFECTION AFTER CYSTOGRAPHY

ABSTRACT Objective: Cystography an invasive procedure with potential complications such as urinary infection (UI). There are few studies about the incidence of complications associated with this procedure. The purpose of this study is to evaluate the incidence of post-cystography urinary infection (UI.). Methods: Retrospective study with a review of clinical records of patients under 15 years of age, followed in this hospital, who underwent cystography (radiologic or indirect radionuclide) between 2009 and 2018. Post-cystography UI was defined when it occurred until seven days after the procedure. Descriptive and nonparametric statistics were applied to assess possible predictive factors related with post-cystography UI. Results: In the study period, 531 cystograms were undertaken (55% indirect radionuclide and 45% radiologic). The mean age at the procedure was 11.5 months; 62% were boys. Every patient had a previous negative urine culture; 50% were under antibiotic prophylaxis at the time of the procedure. The most common indication for the procedure was the post-natal study of congenital hydronephrosis/other nephrological malformation (53%), followed by the study of febrile UI (31%). Vesicoureteral reflux (VUR) was diagnosed in 40% of procedures. Post-cystography UI occurred in 23 cases (incidence of 4.3%). The most frequent microorganism was E. coli (52%). The presence of VUR was significantly associated with the occurrence of post-cystography IU. Conclusions: The incidence of post-cystography UI was low in our sample. The presence of VUR was significantly associated with the occurrence of post-cystography UI. The authors highlight the importance of an adequate catheterization technique and the need for clinical surveillance after the procedure.

Novel catheter design enables transurethral catheterization of male mice

The male mouse is underrepresented in research of the urinary tract due to the difficulty of transurethral catheterization. As a result, there is a lack of analysis of sex differences in urinary tract research. Here, we present a novel catheter design and technique that enables urethral catheterization of male mice for bladder inoculation. Our catheterization technique uses the resistance met at the level of the external urinary sphincter and prostate to guide the retraction, positioning, and advancement of the catheter into the urinary bladder. We have shown that this method can be used to reproducibly catheterize 12 male mice with minimal urogenital trauma but cannot be used as a cystometric technique. This method will facilitate the expansion of research into sex differences in various genitourinary conditions that require transurethral catheterization of mice.

Research on Stroke Rehabilitation Nursing Mode with Senior Nurses as Bond

Objective To explore the effect of rehabilitation nursing model for stroke patients with senior nurses. Methods From October 2017 to October 2018, 46 stroke patients with hemiplegia in community hospitals were selected. 23 stroke patients in community who were willing to accept rehabilitation nursing service package were included in the observation group. The elderly nurses in sinking community were the leading nurses in rehabilitation nursing and home rehabilitation nursing guidance. Community stroke patients without rehabilitation nursing package were selected as control group. Community nurses were the leading nurses in rehabilitation nursing and home-based rehabilitation nursing. The incidence of pressure sores, aspiration rate, accuracy rate of anti-spasm posture placement, and mastery rate of intermittent catheterization technique were compared between the two groups. Results After the intervention, the incidence of pressure ulcer and aspiration rate in the observation group were significantly lower than those in the control group (P < 0.05). The accuracy of anti-spasm posture placement and the mastery rate of intermittent catheterization were significantly higher in the observation group than in the control group (P < 0.05). Conclusion Stroke rehabilitation nursing model with senior nurses as a link has certain effect on rehabilitation nursing of stroke patients in community by strengthening the training, learning and guidance of rehabilitation nursing knowledge and skills of community nurses. Nurses in community hospitals have strengthened two-way linkage, which is of research value, but they are now voluntarily selected in the community. The number of patients choosing rehabilitation care packages is still relatively small, the number of senior nurses in sinking communities is relatively small, and there is still a lot of work to be done to achieve real results. This is a long-term project, which requires time and experience precipitation. Key words Senior nurses; Link; Stroke; Rehabilitation nursing

Tunneled central venous catheterization, a viable option for long-term venous access in pediatric burn patients

Introduction: Pediatric patients with severe burns often require long-term venous access over the course of their recovery. The need for long-term venous access in these critically ill patients often necessitates the placement of a central venous catheter (CVC). Many techniques exist for the establishment of a CVC in pediatric burn patients, and each technique poses its own set of inherent risks. No studies to date have clearly delineated the risk associated with tunneled central venous catheterization in the pediatric burn patient population. The primary aim of this study was to evaluate the use of tunneled CVCs in pediatric burn patients at the University Medical Center Hospital in Lubbock, Texas. Methods: To evaluate this method of central venous catheterization, we retrospectively reviewed the charts of pediatric burn patients who received a tunneled CVC to determine the incidence of specific complications associated with this catheterization technique. We present our findings here in a case series format. Results: Our initial search of patient charts yielded 86 potential candidates for inclusion in the study. After reviewing each chart, 26 pediatric patients were found to have received a CVC. Of these 26 patients, five met all of the inclusion criteria of our study. In these five patients, eight tunneled CVCs were placed. The average age of the patients in this series at the time of their respective burn injuries was 3.9 years old. Mean percent TBSA involvement was 38% with an average length of stay totaling 64.6 days. The average dwell time of the tunneled CVCs in this series was 28 days, and our analysis of the data revealed one tunneled catheterrelated infection and one hemodynamic complication. Conclusions: Overall, our data show that placement of long-term tunneled CVCs in pediatric burn patients appears to be a relatively safe practice. However, our small sample size warrants more investigation into this topic.Keywords: pediatrics, burns, central vein catheters
