ABSTRACT

BACKGROUND OBJECTIVES: In malaria infection, quantifying blood parasitemia is a critical step for evaluating the severity of the disease. This has generally been conducted manually, and thus, its accuracy depends on the expertise of technicians. There is an urgent need for an automated technique to overcome manual errors. The aim of the study is to find an alternative method for counting malaria blood parasitemia.

METHODS: This study evaluated the accuracy of automated counting using QuPath compared to manual counting. GraphPad Kappa evaluated agreement between high and low parasitemia in both counting methods using Cohen’s test.

RESULTS: QuPath was revealed to be a promising method that has fair agreement and no statistically significant differences compared to manual counting.

INTERPRETATION CONCLUSION: In conclusion, automated quantification is suggested to be a time- and effort-saving technique and, therefore, a worthwhile alternative to manual counting.

ABSTRACT

BACKGROUND: Patient transitions in critical care require coordination across provider roles and rely on the quality of providers’ actions to ensure safety. Studying the behavior of providers who transition patients in critical care may guide future interventions that ultimately improve patient safety in this setting.

OBJECTIVE: To establish the feasibility of using the Theory of Planned Behavior in a trauma environment and to describe provider behavior elements during trauma patient transfers (de-escalations) to non-critical care units.

METHODS: This cross-sectional study surveyed a convenience sample of 103 multidisciplinary providers who do the cognitive and physical work of transitioning trauma patients from critical care to another non-critical care unit at a U.S. Level I trauma center. Descriptive methods for survey development, analysis, and administration were evaluated.

RESULTS: A total of 72 respondents completed the survey; they included registered nurses, nurse practitioners, and medical doctors, demonstrating a 70% response rate. Statistically significant differences among ICU roles were observed in perceived control (Eta-squared = 0.09, p = .001) and in several anchors in the attitude, subjective norms, and behavioral intent theoretical domains (Cohen’s d ranging from 0.36 to 2.03, p < .05).

CONCLUSIONS: This study demonstrated variability in theory domains, signaling an opportunity to study a representative sample. It can serve as a blueprint for future behavioral studies designed to examine the Theory of Planned Behavior elements in trauma critical care providers.

ABSTRACT

BACKGROUND: Acute care hospitalization has been associated with older adult home falls after discharge, but less is known about the effects of hospital- and patient-related factors on home fall risk.

OBJECTIVES: This study compares the effects of hospital length of stay, medical condition, history of falls, and home health care on period rates of home falls after discharge from acute care hospitalization.

METHODS: This was a retrospective cohort study comparing period rates of home injury falls among older adults (age ≥ 65) occurring after discharge from an acute care hospitalization. Data were collected from state health care utilization administrative records between January 1, 2016, and December 31, 2018. We used log-linear Poisson regression to model post-discharge injury fall incidence rates as a function of days since discharge and patient-level covariates.

RESULTS: A total of 736,230 older adults were included in the study cohort. Absolute risk for post-discharge home falls was 7%. Fall rates were highest the first week after discharge at 0.05 per 100 person-days, with a period incidence rate 74.29 times higher than the >90-day discharge period. Fall risk increased with age, with the highest risk in the ≥85 age group. Fall risk increased for a 2-day hospital stay but decreased for 5- to 30-day stays, compared to a 1-day length of stay. Discharge to home health care and history of falls were associated with increased risk.

CONCLUSIONS: Older adults are at highest risk for a home fall the first 7 days after discharge from acute care hospitalization. These findings describe patient-related risk factors that acute care hospitals can use to develop geriatric-specific discharge guidelines intended to reduce home fall risk during the early care transition to home.

ABSTRACT

There are multiple surveillance systems working to address the issue of maternal mortality in Missouri. These surveillance systems have key methodological differences in their definitions, terminology, inclusion criteria, and purpose. This study aims to provide an understanding of the practical effects of these programmatic differences regarding what cases are included and how this can impact the interpretations of the data and influence policy decisions. To accomplish this, death certificates identified by the Missouri Vital Statistics program, the Pregnancy Mortality Surveillance System, and the Pregnancy-Associated Mortality Review (PAMR) program were compared. Commonalities and differences were noted, demonstrating the real-world effects of the methodological differences between programs. In particular, the PAMR program includes injury deaths in the count of pregnancy-related deaths, which are not included by other surveillance systems. These differences highlight the importance of understanding the methodology and limitations of a dataset.

ABSTRACT

OBJECTIVE: The study examines: 1) impacts of COVID-19 on the work of Supplemental Nutrition Assistance Program – Education (SNAP-Ed) implementers, 2) facilitators and barriers experienced in making adaptations, and 3) factors that would have helped with preparedness to adapt.

DESIGN, SETTING, AND PARTICIPANTS: A purposive sample of 181 SNAP-Ed program implementers from across five states completed a survey or interview based on the study aims. Quantitative data was summarized with descriptive statistics and qualitative data was analyzed thematically.

RESULTS: Direct education activities were found to be most impacted during COVID-19 while working to change policies, systems, and environments and indirect education were less impacted. Both positive and negative impacts surfaced. Respondents were most likely to say they were moderately or slightly prepared to make adaptations. Elements of internal organizations, technology, and partners both helped and hindered adapting. Pre-established virtual capacity, formal preparation and planning protocols and procedures, and better and more frequent communication with partners and program leadership would have helped with preparedness.

CONCLUSION: SNAP-Ed needs assessment and implementation processes should integrate and expand upon the lessons learned in the study to enhance future emergency preparedness among program implementers. Program policy should be updated to allow for implementation flexibility during future emergencies.

ABSTRACT

OBJECTIVES: The aims of the study were to identify the characteristics of medication-related malpractice claims occurring in the ambulatory setting across 2 time periods.

METHODS: A retrospective, descriptive study was used. Ambulatory medication-related closed malpractice events from loss years of 2011-2021 were analyzed. Analysis included gender and age, injury severity, location, major injury, medications, primary and secondary services, roles, contributing factors, primary drivers, indemnity paid, and disposition status. Findings were analyzed using the Candello Explore tool.

RESULTS: Five hundred four ambulatory medication-related closed malpractice events were included. Family medicine (19.4%) and internal medicine (10.4%) services had the largest number of claims. The top medications were anti-infectants (16.4%), narcotics (15.6%), and anticoagulants (14.4%). Medication-related claims were multifactorial, averaging 4.1 contributing factors per claim. Clinical judgment issues were found in over 55% of the claims, and communication factors were observed in almost 48% of the claims. In the comparison analysis, 433 claims from 2011 to 2015 and 161 claims from 2016 to 2021 were evaluated. A statistical decrease in claims involving anticoagulants and narcotics (P = 0.01) was seen in the second period. There was a statistical increase in claims involving pharmacy dispensing errors during the 2016-2021 period (P = 0.03).

CONCLUSIONS: Adverse drug events in ambulatory care are multifactorial. Errors in the technical process of ordering and managing medications, patient education, patient adherence, and pharmacy dispensing were the primary drivers of ambulatory medication malpractice claims in this study.

ABSTRACT

BACKGROUND: Research data on the extent of and protocols related to physical restraint (PR) in pediatric intensive care units (PICUs) are scarce. Most previous studies in China on this topic have focused on the prevalence, reasons, and background of PR use among adult patients.

PURPOSE: This study was designed to delineate the application of PR and the factors associated with PR use in PICUs in China.

METHODS: A cross-sectional study was conducted in one PICU at West China Hospital, Sichuan University, from January 2020 to December 2020. A total of 1,086 pediatric patients in the PICU were included in this study. Data collection was performed over 11 months, utilizing PR observation forms and patient records. Descriptive statistical analysis was used to obtain the data, and logistic regression models were used to analyze the independent risk factors for PR.

RESULTS: Of the 1,086 participants, 750 (69.1%) experienced being restrained, and 83.5% of the restrained participants who were pediatric patients were restrained for more than 50% of their time during their PICU stay. The results of logistic regression analysis identified age (1-6 years: OR = 2.090, 95% CI [1.508, 2.897], p < .001; 7-17 years: OR = 0.523, 95% CI [0.358, 0.765], p = .001), use of mechanical ventilation (OR = 2.126, 95% CI [1.480, 3.055], p < .001), use of drainage tubes (OR = 1.916, 95% CI [1.445, 2.541], p < .001), and sedation (OR = 1.494, 95% CI [1.101, 2.026], p = .010) as significantly correlated with the use of PR in the PICU. For the 750 patients who experienced being restrained, PR initiation was documented with a written medical order, and in 604 cases (80.5%), the restraints were removed without similar documentation.

CONCLUSIONS: The use of PR is common in PICUs in China, with more than half of pediatric patients being restrained during their stay. Age, mechanical ventilation, use of drainage tubes, and use of sedative drugs were identified as significantly associated with PR use. Developing standardized procedures/guidelines for PR use in Chinese PICUs and enhancing medical staff education on PR practices are imperative.

ABSTRACT

In recent decades there has been significant interest among policy makers in supporting entrepreneurship among university students, with the goal to improve labor market outcomes and contribute to the economy through venture creation. Drawing from the 2018 National Graduate Survey in Canada, our study examines who engages in entrepreneurial activity after graduation, investigating differences among demographic groups and between those who participated in entrepreneurship education on campus and those who did not participate. We find that those graduates who participated in entrepreneurship education are more likely to be self-employed and own their own business three years after graduating than the general population of university graduates. We also find differences according to gender, citizenship, and socio-economic status in entrepreneurial activity. Our results are consistent with previous studies documenting demographic disparities in entrepreneurship and provide more generalizable evidence about the relationship between entrepreneurship education and subsequent entrepreneurship.

ABSTRACT

OBJECTIVE: Blood urea nitrogen (BUN) is a commonly used biomarker for assessing kidney function and neuroendocrine activity. Previous studies have indicated that elevated BUN levels are associated with increased mortality in various critically ill patient populations. The focus of this study was to investigate the relationship between BUN and 28-day mortality in intensive care patients.

METHODS: This was a multi-centre retrospective cohort study that made use of data from the eICU Collaborative Research Database. The primary exposure variable was BUN, and the outcome was 28-day mortality. The following variables were included as covariates: age, gender, BMI, white blood cell count, creatinine, GCS score, APACHE IV score, and diabetes. The statistical analyses included univariate and multivariate logistic regression, as well as generalized additive modelling, which was employed to assess the non-linear relationship between BUN and mortality.

RESULTS: A total of 63,757 elderly patients were included in the study, with a 28-day mortality of 6.5%. The univariate analysis indicated that elevated BUN quartiles were associated with an increased risk of mortality. The results of the multivariate analysis further confirmed the non-linear relationship between BUN and mortality. When BUN was less than 32 mg/dL, there was a significant positive association, with an adjusted odds ratio of 1.230 (95% CI: 1.154-1.311, p<0.0001) for every 10 mg/dL increase in BUN. However, when BUN was greater than or equal to 32 mg/dL, BUN level had no significant effect on mortality.

CONCLUSION: BUN showed a nonlinear, threshold correlation with 28-day mortality in critically ill patients. The higher the BUN, the greater the risk of death if the BUN is below the threshold.

ABSTRACT

Chronic pain is a wide-spread condition that is debilitating and expensive to manage, costing the United States alone around $600 billion in 2010. In a common symptom of chronic pain called allodynia, non-painful stimuli produce painful responses with highly variable presentations across individuals. While the specific mechanisms remain unclear, allodynia is hypothesized to be caused by the dysregulation of excitatory-inhibitory (E-I) balance in pain-processing neural circuitry in the dorsal horn of the spinal cord. In this work, we analyze biophysically-motivated subcircuit structures that represent common motifs in neural circuits in laminae I-II of the dorsal horn. These circuits are hypothesized to be part of the neural pathways that mediate two different types of allodynia: static and dynamic. We use neural firing rate models to describe the activity of populations of excitatory and inhibitory interneurons within each subcircuit. By accounting for experimentally-observed responses under healthy conditions, we specify model parameters defining populations of subcircuits that yield typical behavior under normal conditions. Then, we implement a sensitivity analysis approach to identify the mechanisms most likely to cause allodynia-producing dysregulation of the subcircuit’s E-I signaling. We find that disruption of E-I balance generally occurs either due to downregulation of inhibitory signaling so that excitatory neurons are “released” from inhibitory control, or due to upregulation of excitatory neuron responses so that excitatory neurons “escape” their inhibitory control. Which of these mechanisms is most likely to occur, the subcircuit components involved in the mechanism, and the proportion of subcircuits exhibiting the mechanism can vary depending on the subcircuit structure. These results suggest specific hypotheses about diverse mechanisms that may be most likely responsible for allodynia, thus offering predictions for the high interindividual variability observed in allodynia and identifying targets for further experimental studies on the underlying mechanisms of this chronic pain symptom.
