Parent Experiences and Perceptions of Safety When Transporting Children With Autism Spectrum Disorder

Am J Occup Ther. 2021 Sep 1;75(5):7505205010. doi: 10.5014/ajot.2021.041749.

ABSTRACT

IMPORTANCE: Motor vehicle accidents are the leading cause of unintentional deaths of children ages 1 and older, particularly children with health care needs.

OBJECTIVE: To explore family caregivers’ experiences and current practices while transporting children diagnosed with autism spectrum disorder (ASD).

DESIGN: A concurrent nested mixed-methods approach was used to gain insight into caregiver experiences.

SETTING: Participants completed an online Qualtrics survey.

PARTICIPANTS: A convenience sample of 54 caregivers of children with ASD from 17 U.S. states.

RESULTS: Themes that emerged include sensory behaviors of children, education related to child passenger safety, and participation in the community. Statistically significant findings suggest a correlation between caregivers (n = 39) being less likely to participate in activities away from home if the child had attempted to elope (p = .013), displayed aggressive behaviors (p = .005), or demonstrated self-injurious behaviors (p = .001).

CONCLUSIONS AND RELEVANCE: The findings suggest a correlation between caregivers limiting the distance traveled during vehicular transportation and behavioral safety concerns. If caregivers must limit travel, they may refrain from accessing the community and engaging in leisure pursuits. What This Article Adds: The findings suggest that therapists who treat children with ASD should be familiar with child passenger safety restraints, particularly for elopement.

Occupational Therapist Treatment of Patients in the Neurological Critical Care Unit: Utilization and Patient Characteristics

Am J Occup Ther. 2021 Sep 1;75(5):7505205020. doi: 10.5014/ajot.2021.041087.

ABSTRACT

IMPORTANCE: Occupational therapy use in the neurological critical care unit (NCCU) may relate to patient factors, but data about these relationships remain unpublished.

OBJECTIVE: To examine how patient factors predict NCCU occupational therapy use and intervention types.

DESIGN: Retrospective cohort study of electronic health records data from adults admitted to the NCCU between May 2013 and September 2015.

SETTING: NCCU in a large, urban academic hospital.

PARTICIPANTS: Adults (age ≥18 yr; N = 1,134) admitted to the NCCU.

MEASURES: Using length of stay (LOS), number of comorbidities, Glasgow Coma Scale (GCS) score, gender, age, and racial-ethnic minority status as independent variables, separate regression models identified predictors for each dependent variable: receipt of NCCU occupational therapy, occupational therapy onset (days after admission), and receipt of self-care or home management (ADL-Home); functional activities or cognitive training (Func-Cog); and therapeutic exercise (Ther-Ex).

RESULTS: Four hundred twenty patients (37.0%) received occupational therapy in the NCCU. Receipt of occupational therapy was positively associated with LOS, number of comorbidities, GCS score, and age. Earlier occupational therapy onset was associated with higher GCS score and shorter LOS. Receipt of ADL-Home or Func-Cog interventions was significantly predicted by number of occupational therapy sessions, but patients with longer LOS were less likely to receive ADL-Home interventions. Receipt of Ther-Ex interventions became less likely as GCS score increased.

CONCLUSIONS AND RELEVANCE: Patients are more likely to receive occupational therapy services if they are older and have a longer NCCU LOS, more comorbidities, and a higher level of consciousness. What This Article Adds: A patient’s level of consciousness is clearly associated with occupational therapy utilization and hospital outcomes, but it should not be the only factor considered when prioritizing patients for NCCU occupational therapy services. Compared with patients who were more awake and alert, patients with a lower level of consciousness had a later onset of occupational therapy, which suggests an opportunity for NCCU occupational therapists to collaborate with physicians in the modification of sedation protocols to enable early rehabilitation.

Effects of Self-Regulated Physical Activity in Premature Infants on Bone Density and Length of Stay: A Pilot Study

Am J Occup Ther. 2021 Sep 1;75(5):7505205040. doi: 10.5014/ajot.2021.039487.

ABSTRACT

IMPORTANCE: Premature infants are not prepared developmentally, physically, or cognitively with the multiple survival skills of the typical newborn.

OBJECTIVE: To determine whether physical activity generated spontaneously by premature infants stretching against the resistance of “prepod” garments is as effective as exercises provided by therapists in slowing bone density loss.

DESIGN: Preterm very low birth weight infants were placed in two nonrandomized parallel groups according to birth age.

SETTING: Infants routinely started in a traditional intense intervention setting and graduated to a special care section with private rooms that allowed parents to remain with their child.

PARTICIPANTS: Healthy infants without medical complications, born between 28 and 32 wk postmenstrual age.

INTERVENTION: The control group received traditional exercises. The experimental group wore a prepod almost 24 hr a day. Outcomes and Measures: An ultrasound of the tibia was obtained at 31 to 32 wk and 4 wk later. Weight gain, head circumference growth, and length of stay (LOS) were also measured.

RESULTS: Although not statistically significant, the ultrasound results showed that the prepod group had less loss of bone density than the traditional therapy exercise group. The desired outcome was for pods to be as effective at reducing bone loss as traditional exercise, so the results exceeded expectations. The unexpected, and more notable, finding was a striking drop in LOS for the prepod group.

CONCLUSIONS AND RELEVANCE: Spontaneous exercise by premature infants decreases bone loss and LOS. Better bone health and increased developmental maturity increase the chances of a positive developmental outcome and save the hospital significant expense. What This Article Adds: The prepod is a simple, cost-effective, noninvasive treatment tool occupational therapy practitioners can use to support a premature infant’s development. This study has considerable potential to affect how infants are served, both developmentally and financially.

Applied aerial spectroscopy: A case study on remote sensing of an ancient and semi-natural woodland

PLoS One. 2021 Nov 15;16(11):e0260056. doi: 10.1371/journal.pone.0260056. eCollection 2021.

ABSTRACT

An area of ancient and semi-natural woodland (ASNW) has been investigated by applied aerial spectroscopy using an unmanned aerial vehicle (UAV) with multispectral image (MSI) camera. A novel normalised difference spectral index (NDSI) algorithm was developed using principal component analysis (PCA). This novel NDSI was then combined with a simple segmentation method of thresholding and applied for the identification of native tree species as well as the overall health of the woodland. Using this new approach allowed the identification of trees at canopy level, across 7.4 hectares (73,934 m2) of ASNW, as oak (53%), silver birch (37%), empty space (9%) and dead trees (1%). This UAV derived data was corroborated, for its accuracy, by a statistically valid ground-level field study that identified oak (47%), silver birch (46%) and dead trees (7.4%). This simple innovative approach, using a low-cost multirotor UAV with MSI camera, is both rapid to deploy, was flown around 100 m above ground level, provides useable high resolution (5.3 cm / pixel) data within 22 mins that can be interrogated using readily available PC-based software to identify tree species. In addition, it provides an overall oversight of woodland health and has the potential to inform a future woodland regeneration strategy.

Utilization of growth monitoring and promotion services and associated factors among children aged 0-23 months in Banja District, Northwest Ethiopia 2020: A cross-sectional study

PLoS One. 2021 Nov 15;16(11):e0259968. doi: 10.1371/journal.pone.0259968. eCollection 2021.

ABSTRACT

BACKGROUND: Growth monitoring and promotion are the basic malnutrition preventive strategies usually used to assess the growth of children using anthropometric measurements in comparison with world health organization standards. However, the utilization of growth monitoring and promotion services is inadequate in most developing countries. Therefore, this study aimed to assess the utilization of growth monitoring and promotion service and associated factors among children aged 0-23-month in Banja District, Northwest Ethiopia, 2020.

METHODS: A community-based cross-sectional study was conducted from February 2 to April 1, 2020. A total of 572 children were selected using a simple random sampling technique. Data were collected using structured and pre-tested interviewer-administered questionnaires. Data were entered into Epi data version 4.6 and analyzed using the statistical package for social science (SPSS) version 25. Both binary and multivariable logistic regression analyses with a 95% confidence level were used to identify the associated factors. Statistical significance was set at p <0.05.

RESULTS: This finding revealed that the proportion of growth monitoring and promotion services utilization was 38.9% [95%CI: 34.8%, 43.0%]. Child age from 0-11 months [AOR = 4.98 (95% CI: 2.75,8.37)], mothers who can read and write Amharic language [AOR = 2.04 (95%CI: 1.02,4.08)], know the benefits of weighing their child monthly [AOR = 2.9 (95%CI: 1.23, 6.94)], presence of growth monitoring service nearby [AOR = 3.2 (95%CI: 1.59,6.31)] and monthly income ≥2000 Ethiopian birr [AOR = 1.75(95% CI = 1.08, 3.02)] were some of the factors significantly associated with utilization of growth monitoring and promotion services.

CONCLUSION AND RECOMMENDATION: The findings indicate that utilization of growth monitoring and promotion services is mainly affected by child age, mother/caregiver ability to read and write Amharic language, having maternal information on the benefit of the weighing child, presence of service nearby health facility, and mother/caregiver monthly income. Preparation of growth monitoring charts in local language (Awigna) and creating awareness on the proper utilization of growth monitoring and promotion services is strongly recommended.

Management practices and their relation to success of Polish SMEs: The empirical verification

PLoS One. 2021 Nov 15;16(11):e0259892. doi: 10.1371/journal.pone.0259892. eCollection 2021.

ABSTRACT

PURPOSE: The aim of the paper is to identify management practices that are characteristic for SMEs that achieve market success measured by their business performance in last their years of their operation analyze the relationships between management practices applied in small and medium-sized enterprises and their success measured by their business performance drawing on the data from 2710 SMEs operating on the Polish market.

APPROACH/METHODOLOGY/DESIGN: A cluster analysis was used to distinguish homogenous SME groups in view of their management practices. We examined differences between groups in terms of their business performance. The HINoV algorithm allowed six variables to be selected out of 32 management practices chosen initially for testing, with these variables providing the basis for grouping. Modal values and medians were calculated for 17 business performance measures in the three clusters produced. The subsequent analysis of those findings was focused on capturing significant differences.

FINDINGS: In the group of 2710 Polish SMEs, it was possible to verify that there existed an association between management practices in the field of modern HRM, computer systems supporting management and the company’s economic performance, as measured by an increase in net revenue and number of customers over the last three years. In clusters where the above mentioned practices were appreciated, modal and median values of the increase reported in net revenue and number of customers were significantly higher.

PRACTICAL IMPLICATIONS: The research has shown that at a time marked by a shortage of highly skilled personnel one should pay particular attention to building an integrated and committed team of workers and to employee empowerment. The research has also shown that SME managers monitor only a fraction of basic business performance measures, which may prove to be a major risk to SMEs.

ORIGINALITY/VALUE: Previous studies have been largely conducted in a fragmentary manner, i.e. they were concerned with the relationships between the application of some practices (strategic management, BPR, entrepreneurial orientation, monitoring, etc.) and selected business effectiveness measures. In this paper, the research covered SME management practices from a variety of areas which were then compared with the entrepreneurs’ assessment as to whether the company’s economic condition changed over the last three years. It is also the first attempt in post-socialist economies to identify those SME management practices that are related to better economic results.

The aggregate effect of implementation strength of family planning programs on modern contraceptive use at the health systems level in rural Malawi

PLoS One. 2021 Nov 15;16(11):e0232504. doi: 10.1371/journal.pone.0232504. eCollection 2021.

ABSTRACT

To explore the association between the strength of implementation of family planning (FP) programs on the use of modern contraceptives. Specifically, how strongly these programs are being implemented across a health facility’s catchment area in Malawi and the odds of a woman in that catchment area is using modern contraceptives. This information can be used to assess whether the combined impact of multiple large-scale FP programs is leading to change in the health outcomes they aim to improve. We used data from the 2017 Implementation Strength Assessment (ISA) that quantified how much of family planning programs at the health facility and community health worker levels were being implemented across every district of Malawi. We used a summary measure developed in a previous study that employs quantitative methods to combine data across FP domains and health system levels. We tested the association of this summary measure for implementation strength with household data from the 2015 Malawi Demographic Health Survey (DHS). We found that areas with stronger implementation of FP programs had higher odds of women using modern contraceptives compared with areas with weaker implementation. The association of ISA with use of modern contraception was different by education, marital status, and geography. After controlling for these factors, we found that the adjusted odds of using a modern contraceptive was three times higher in catchment areas with high implementation strength compared to those with lower strength. Metrics that summarize how strongly FP programs are being implemented were used to show a statistically significantly positive relationship between increasing implementation strength and higher rates of modern contraceptive use. Decisionmakers at the various levels of health authority can use this type of summary measure to better understand the combined impact of their diverse FP programming and inform future programmatic and policy decisions. The findings also reinforce the idea that having a well-supported and supplied cadre of community health workers supplementing FP provision at the health facility can be an important health systems mechanism, especially in rural settings and to target youth populations.

Internal and external drivers for compliance with the COVID-19 preventive measures in Slovenia: The view from general deterrence and protection motivation

PLoS One. 2021 Nov 15;16(11):e0259675. doi: 10.1371/journal.pone.0259675. eCollection 2021.

ABSTRACT

The emergence of a pandemic is usually accompanied by different measures-economic, social, preventive, and (self)protective. In the case of the COVID-19, several preventive measures were formally enforced by state authorities in the majority of countries worldwide. Thus, during the COVID-19 pandemic, the intertwining of formal and informal social control could be observed. Hence, in this study a cross-sectional design was chosen to explore the issue in Slovenia. To the best of our knowledge, this research is the first in the current literature to empirically test the general deterrence theory in pandemic circumstances (as external factors predicting individuals’ compliance with the COVID-19 preventive measures). The results suggest an important role of informal punishment, with perceived informal severity being the only statistically significant factor from the general deterrence theory. In contrast to external factors, internal factors play a significantly greater role in promoting people’s self-protective behavior in pandemic circumstances. During the unknown, the uncertain and delicate situations with which people have no previous experience, both personal beliefs about the effectiveness of measures and perceived self-efficacy are more important than fear of formal sanctions.

Antimicrobial resistance profiles and associated factors of Acinetobacter and Pseudomonas aeruginosa nosocomial infection among patients admitted at Dessie comprehensive specialized Hospital, North-East Ethiopia. A cross-sectional study

PLoS One. 2021 Nov 15;16(11):e0257272. doi: 10.1371/journal.pone.0257272. eCollection 2021.

ABSTRACT

INTRODUCTION: Hospital admitted patients are at increased risk of nosocomial infections (NIs) with multi-drug resistant (MDR) pathogens which are prevalent in the hospital environment. Pseudomonas aeruginosa (P. aeruginosa) and Acinetobacter baumannii (A. baumannii) are common causes of NIs worldwide. The objective of this study is to determine antimicrobial resistance profiles and associated factors of Acinetobacter spp and P. aeruginosa NIs among hospitalized patients.

METHODS: A cross-sectional study was conducted at Dessie comprehensive specialized hospital, North-East Ethiopia, from February 1 to April 30, 2020. A total of 254 patients who were suspected of the bloodstream, urinary tract, or surgical site nosocomial infections were enrolled consecutively. Socio-demographic and other variables of interest were collected using a structured questionnaire. Specimens were collected and processed following standard microbiological procedures. Antimicrobial susceptibility was determined using the Kirby-Bauer disk diffusion method following Clinical and Laboratory Standards Institute guidelines. Data were analyzed with SPSS version 23 and p-value < 0.05 was considered statistically significant.

RESULTS: Overall, 13% of patients had nosocomial Acinetobacter spp and/or P. aeruginosa infections. The culture positivity rate was 16(6.3%) for Acinetobacter spp and 18(7.1%) for P. aeruginosa. Patients admitted in the surgical ward (Adjusted odds ratio (AOR):10.66;95% confidence interval (CI):1.22-93.23), pediatric ward (AOR:14.37;95%CI:1.4-148.5), intensive care unit (AOR:41.93;95%CI:4.7-374.7) and orthopedics (AOR:52.21;95%CI:7.5-365) were significantly at risk to develop NIs compared to patients admitted in the medical ward. Patients who took more than two antimicrobial types at admission were 94% (AOR:0.06; 95% CI:0.004-0.84) times more protected from NIs compared to those who did not take any antimicrobial. About 81% of Acinetobacter spp and 83% of P. aeruginosa isolates were MDR. Amikacin and meropenem showed promising activity against Acinetobacter spp and P. aeruginosa isolates.

CONCLUSION: The high prevalence of MDR Acinetobacter spp and P. aeruginosa nosocomial isolates enforce treating of patients with NIs based on antimicrobial susceptibility testing results.
