Medical Device Design Education: Identifying Problems Through Observation and Hands-On Training

Experiential learning, which may include hands-on learning paired with observation and reflection, has been applied in several industries; however, the impact of experiential learning in design education is not well known. We investigated how the type of simulation-based learning could affect the acquisition of knowledge and the ability to synthesize that understanding into insights for medical design innovation. One workshop included observational learning and the other experiential learning with hands-on training. Each course included 14-16 multidisciplinary undergraduate and graduate students. During both workshops, we measured student comprehension of two procedures— infant resuscitation and management of maternal hemorrhage. We focused on the first two phases of design thinking: “Understanding” and “Defining the Problems”. Although the course focused on “medical device design”, we encouraged students to look beyond the tool to imagine how their design change could impact the entire system. We did not find a significant difference between the scores given to students in the two courses by industry experts. Although the quality of the ideas and execution were similar between both workshops, the instructors noticed that the integration of hands-on training into the second workshop created a higher level of excitement in the class. The methodology and the approach adopted may be relevant to many design problems. In order to better understand the impact of observational learning versus hands-on training, both workshops could be expanded into full quarter classes that allow students to expand their design thinking skills to prototype and test their ideas in the real world

Microbiological Evaluation of Water Quality from Urban Watersheds for Domestic Water Supply Improvement

Agricultural and urban runoffs may be major sources of pollution of water bodies and major sources of bacteria affecting the quality of drinking water. Of the different pathways by which bacterial pathogens can enter drinking water, this one has received little attention to date; that is, because soils are often considered to be near perfect filters for the transport of bacterial pathogens through the subsoil to groundwater. The goals of this study were to determine the distribution, diversity, and antimicrobial resistance of pathogenic Escherichia coli isolates from low flowing river water and sediment with inputs from different sources before water is discharged into ground water and to compare microbial contamination in water and sediment at different sampling sites. Water and sediment samples were collected from 19 locations throughout the watershed for the isolation of pathogenic E. coli. Heterotrophic plate counts and E. coli were also determined after running tertiary treated water through two tanks containing aquifer sand material. Presumptive pathogenic E. coli isolates were obtained and characterized for virulent factors and antimicrobial resistance. None of the isolates was confirmed as Shiga toxin E. coli (STEC), but as others, such as enterotoxigenic E. coli (ETEC). Pulsed field gel electrophoresis (PFGE) was used to show the diversity E. coli populations from different sources throughout the watershed. Seventy six percent of the isolates from urban sources exhibited resistance to more than one antimicrobial agent. A subsequent filtration experiment after water has gone through filtration tanks containing aquifer sand material showed that there was a 1 to 2 log reduction in E. coli in aquifer sand tank. Our data showed multiple strains of E. coli without virulence attributes, but with high distribution of resistant phenotypes. Therefore, the occurrence of E. coli with multiple resistances in the environment is a matter of great concern due to possible transfer of resistant genes from nonpathogenic to pathogenic strains that may result in increased duration and severity of morbidity

Self-Compassion, Anticipatory Anxiety, and Fear of Evaluation in Social Anxiety

Self-compassion involves treating yourself with kindness instead of judgement, understanding that pain and failure is experienced by everyone instead of isolating oneself, and being mindfully aware of painful thoughts and feelings instead of ruminating on them (Neff, 2003). The present study is interested in self-compassion\u27s effect on social anxiety; it is a replication of a recent study (Harwood & Kocovski, 2017) and an attempt to extend its findings. Harwood and Kocovski (2017) found that, among participants higher in social anxiety, those who completed a self-compassion writing task experienced less anticipatory anxiety before a speech task in comparison to those who had completed a control writing task. The present study includes the addition of two dependent variables, fear of positive and negative evaluation, in order to examine how the same self-compassion exercise may also impact the fear of evaluation that individuals with social anxiety may experience before the same socially stressful speech task. Some research has already shown a correlation between self-compassion and fear of evaluation; less self-compassion is associated with greater fear of both positive and negative evaluation (Werner et al., 2012; Long & Neff, 2018). The following has been hypothesized, and will be tested once data collection has been completed: (1) In line with previous research (Harwood & Kocovski 2017), the self-compassion writing task will reduce anticipatory anxiety more for those higher in social anxiety (2) The self-compassion writing task will reduce fear of negative evaluation for those higher in social anxiety, and (3) The self-compassion writing task will reduce fear of positive evaluation for those higher in social anxiety. The current literature has evidence that the self-compassion exercise can lower anticipatory anxiety (Harwood & Kocovski, 2017), so if it is shown that it also lowers fear of evaluation, the literature may have even stronger evidence that self-compassion exercises could potentially play a role in making exposure easier for those with social anxiety

A prospective clinical study of Primo-Lacto: A closed system for colostrum collection.

BACKGROUND:Colostrum is the first nutritional liquid that comes out of the breast during lactation. Colostrum collection can be challenging due to the small volume produced, and because breast pumps are not designed for colostrum collection. Besides pumping colostrum, the generally accepted practice is to use any available container to hand-express colostrum. Transfer between containers may lead to contamination, higher chance of infection and loss of colostrum. Our aim was to understand if a dedicated colostrum collection system (Primo-Lacto, Maternal Life, LLC, Palo Alto, CA) is more effective than standard hospital practice. METHODS:Mothers who delivered preterm infants < 34 weeks gestation and mothers with non-latching infants were approached within 24 hours of delivery. Surveys were distributed to participating patients (n = 67), and nurses or lactation consultants (n = 89). Mothers compared ease of use, their confidence level and satisfaction with the amount collected during standard practice vs. the colostrum collection system. Nurses or lactation consultants compared ease of use, differences in colostrum loss and time invested collecting. Quantitative data were analyzed using the Wilcoxon signed rank test and qualitative data were analyzed with grounded theory methods. RESULTS:For mothers, ease of use and confidence were significantly better when they used the colostrum collection system than when they used the standard collection procedure, and this difference was true for both hand and pump expression (p<0.01). Nurses and lactation consultants perceived that ease of use was better, and percent of colostrum lost was significantly less with the colostrum collection system for both hand and pump expression. The collection times were not significantly different between the colostrum collection system and standard practice. CONCLUSION:The colostrum collection system is a tool to help facilitate successful colostrum collection and improve the experience both for clinicians and patients

Pharmacist Engagement within a Hepatitis C Ambulatory Care Clinic in the Era of a Treatment Revolution

Objectives: To describe an innovative hepatitis C virus (HCV) care program and treatment outcomes resulting from pharmacist services. Setting: Adult ambulatory care HCV clinic within the Miami Veteran Affairs Healthcare System. Practice description: Pharmacists with limited prescriptive authority are integrated into a medical hepatology care team. Practice innovation: Pharmacists screen patients with HCV infection for treatment eligibility, counsel patients upon treatment initiation, assess ongoing treatment success and toxicity through patient appointments, telephone calls, and the ordering of pertinent laboratory data, and provide oversight of all patients on HCV therapies. Treatment outcomes are reported to the institutional Antimicrobial Stewardship Program. Evaluation: Data produced from a continuous quality assurance initiative were utilized. Descriptive statistics were used to present data. Results: From January 2014 through September 2015 there were 1619 pharmacist encounters for 532 unique patients and 597 screenings (including 578 approvals) were completed by a pharmacist. During this time 555 patients were initiated on at least 1 HCV treatment course, with 565 total treatment courses initiated. As new agents became available for use, fluctuation in regimen selection was seen. The most commonly prescribed medications were sofosbuvir (46%), ledipasvir/sofosbuvir (37%), and simeprevir (33%). Of the 565 HCV treatment courses initiated, 360 were completed, 29 were stopped early during treatment, and 176 were ongoing. Of the 360 completed courses, 249 had sustained virologic response at week 12 results available, of which 225 (90%) achieved treatment success and 24 (10%) relapsed. Of the 29 courses stopped early, 11 were due to poor medication adherence and 8 were due to adverse drug reaction. Conclusion: Through a structured process employing a scope of practice, pharmacists can extend the capacity of medical hepatology providers and provide pharmacotherapy services to enhance care. Information provided here may serve beneficial to others looking to initiate or expand existing HCV pharmacist services

Systematic review of school-based interventions to prevent smoking for girls.

BackgroundThe purpose of this review is to study the effect of school-based interventions on smoking prevention for girls.MethodsWe performed a systematic review of articles published since 1992 on school-based tobacco-control interventions in controlled trials for smoking prevention among children. We searched the databases of PubMed, Embase, Web of Science, The Cochrane Databases, CINAHL, Social Science Abstracts, and PsycInfo. Two reviewers independently assessed trials for inclusion and quality and extracted data. A pooled random-effects estimate was estimated of the overall relative risk.ResultsThirty-seven trials were included, of which 16 trials with 24,210 girls were included in the pooled analysis. The overall pooled effect was a relative risk (RR) of 0.96 (95&nbsp;% confidence interval (CI) 0.86-1.08; I (2)=75&nbsp;%). One study in which a school-based intervention was combined with a mass media intervention showed more promising results compared to only school-based prevention, and four studies with girl-specific interventions, that could not be included in the pooled analysis, reported statistically significant benefits for attitudes and intentions about smoking and quit rates.ConclusionsThere was no evidence that school-based smoking prevention programs have a significant effect on preventing adolescent girls from smoking. Combining school-based programs with mass media interventions, and developing girl-specific interventions, deserve additional study as potentially more effective interventions compared to school-based-only intervention programs.Systematic review registrationPROSPERO CRD42012002322

Analyzing the heterogeneity of labor and delivery units: A quantitative analysis of space and design.

This study assessed labor and delivery (L&D) unit space and design, and also considered correlations between physical space measurements and clinical outcomes. Design and human factors research has increased standardization in high-hazard industries, but is not fully utilized in medicine. Emergency department and intensive care unit space has been studied, but optimal L&D unit design is undefined. In this prospective, observational study, a multidisciplinary team assessed physical characteristics of ten L&D units. Design measurements were analyzed with California Maternal Quality Care Collaborative (CMQCC) data from 34,161 deliveries at these hospitals. The hospitals ranged in delivery volumes (5000 annual deliveries) and cesarean section rates (19.6%-39.7%). Within and among units there was significant heterogeneity in labor room (LR) and operating room (OR) size, count, and number of configurations. There was significant homogeneity of room equipment. Delivery volumes correlated with unit size, room counts, and cesarean delivery rates. Relative risk of cesarean section was modestly increased when certain variables were above average (delivery volume, unit size, LR count, OR count, OR configuration count, LR to OR distance, unit utilization) or below average (LR size, OR size, LR configuration count). Existing variation suggests a gold standard design has yet to be adopted for L&D. A design-centered approach identified opportunities for standardization: 1) L&D unit size and 2) room counts based on current or projected delivery volume, and 3) LR and OR size and equipment. When combined with further human factors research, these guidelines could help design the L&D unit of the future
