RESUMO

Environmental pollution problems caused by the use of fossil fuels have led to the search for renewable energy sources to mitigate greenhouse gas emissions. In addition, constructed wetlands-microbial fuel cells (CW-MFC) could contribute to sustainable development, considering that this technology focuses on the production of bioelectricity. One of the main challenges of CW-MFCs is to potentiate their bioelectrochemical performance. Therefore, this research used the Geobacter sulfurreducens DL-1 bacterium (biofilm) as a bioelectrocatalyst to increase bioelectricity generation. For this, three bioreactors were built as CW-MFCs, using Juncus effusus root exudates and Philodendron cordatum macrophytes as endogenous substrates. The biofilm was developed in a nutrient broth acetate fumarate and directly inoculated onto the anodes of each CW-MFC. The results of bioelectrochemical analyses showed that the biofilm generated more bioelectricity when it consumed the exudates of the Juncus effusus macrophyte, resulting in a maximum performance of 107 mW/m2 power density, -361 mV anodic potential, 290 mV cathodic potential, and 124 Ω internal resistance, using a concentration of 27.5 mg/L of total organic carbon as an endogenous substrate. The results determined that the quantity of root exudates consumed by the anodic biofilm is directly related to the production of bioelectricity in CW-MFCs.

RESUMO

OBJECTIVES: There is extensive literature from various disciplines on self-care, an important aspect of nursing intervention via evaluation and education, but its meaning remains unprecise due to the difficulty integrating the diverse definitions developed over time across disciplines. Therefore, it is vital to clarify the meaning of self-care and formulate the defining attributes, antecedents, and consequences to self-care. METHODS: Walker and Avant's concept analysis approach was used to analyze the concept of self-care. A search of the literature was completed using the databases CINAHL, PubMed, and EBSCOhost for years 1975-2020; literature search included peer-review articles, full-text publications, and available in English. A total of 31 articles were reviewed, and saturation was reached. RESULTS: An extensive review of the literature revealed salient characteristics that reflected the most frequently used terms associated with the concept. Guided by Walker and Avant's method, three defining attributes emerged as common themes: awareness, self-control, and self-reliance. CONCLUSIONS: A clarified definition was identified: the ability to care for oneself through awareness, self-control, and self-reliance in order to achieve, maintain, or promote optimal health and well-being.

RESUMO

Purpose: Increasing patient activation facilitates self-management of health, improves health outcomes, and lowers health care expenditures. Extant research notes mixed findings in patient activation by race/ethnicity. The purpose of the study was to examine the relationships among patient activation, select patient characteristics, and glycemic control among Filipino Americans. Methods: A cross-sectional study was conducted with a convenience sample of Filipino Americans (n=191), with a diagnosis of diabetes mellitus type 1 or type 2, recruited from a southern California adult primary care clinic between December 2017 and March 2018. Patient activation, select characteristics, and hemoglobin A1c (HbA1c) levels were assessed. Bivariate and logistic regression analyses were used to identify correlates of glycemic control. The Strengthening the Reporting of Observational studies in Epidemiology (STROBE) checklist was used to develop the study. Results: Participants with HgbA1C≤7.0% reported statistically higher patient activation measure (13 items) (PAM-13) natural log score (mean [M]=60.32, standard deviation [SD]=13.50) compared to those with an HgbA1C>7.0%, M=52.58, SD=10.19, F(1)=11.05, p<0.001. Multivariate logistic regression using age, low-density lipoprotein, and PAM-13 natural log was statistically reliable distinguishing between A1C≤7.0 and A1C>7.0, -2 LogLikehood=1183.23, χ 2(3)=15.44, p<0.001. Conclusions: Patient activation is an important factor in supporting glycemic control. Findings support interventions to target patient activation. Providers are encouraged to use racial/ethnic-centered engagement strategies in resolving health disparity with racial and ethnic minorities to facilitate patient activation and improve health outcomes in patients with diabetes.

RESUMO

Purpose: To assess whether individuals attending a community clinic had the necessary Internet access and experience to use the patient portal, while examining covariates of education, income, and self-perception of health with past and anticipated portal use. Methods: Adults attending an urban, community primary care clinic were invited to participate in a brief survey assessing current Internet access and use, past portal use, and anticipated future portal use. Survey responses were analyzed using descriptive and multivariate statistics. Results: One hundred fifteen participants ranging in age from 18 to 84 years (mean 42.1, standard deviation 17.1) completed the survey; 6 (5%) in Spanish. Thirty-five (30%) self-identified as Latino; 12 (10%) as Asian; and 20 (17%) as other. Almost 80% reported their health as good or better. Although 38% reported some college and 47% reported being college graduates, 60% reported household incomes were <$50,000. Most (87%) used the Internet for >1 year. Fewer than half (42%) had past portal use, with significant differences associated with weekly Internet use (Fisher's exact=9.59; p=0.02) and smart phone access (Fisher's exact=6.15; p=0.02). Computer Internet access was significantly associated with income (Fisher's exact=16.91; p<0.001). Logistic regression identified that computer Internet access was a significant predictor (odds ratio 9.9 (95% confidence interval: 1.7-58.8) of future portal use, controlling for smart phone use, health status, gender, and age. Conclusions: Among this highly educated but lower economic sample, computer Internet access and smart phone access were associated with past portal use and anticipated future use.

RESUMO

OBJECTIVES: Globally, healthcare systems are using the Electronic Health Record (EHR) and elements of clinical decision support (CDS) to facilitate palliative care (PC). Examination of published results is needed to determine if the EHR is successfully supporting the multidisciplinary nature and complexity of PC by identifying applications, methodology, outcomes, and barriers of active incorporation of the EHR in PC clinical workflow. METHODS: A systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The data sources PubMed, CINAL, EBSCOhost, and Academic Search Premier were used to identify literature published 1999 - 2017 of human subject peer-reviewed articles in English containing original research about the EHR and PC. RESULTS: The search returned 433 articles, 30 of which met inclusion criteria. Most studies were feasibility studies or retrospective cohort analyses; one study incorporated prospective longitudinal mixed methods. Twenty-three of 30 (77%) were published after 2014. The review identified five major areas in which the EHR is used to support PC. Studies focused on CDS to: identify individuals who could benefit from PC; electronic advanced care planning (ACP) documentation; patient-reported outcome measures (PROMs) such as rapid, real-time pain feedback; to augment EHR PC data capture capabilities; ,and to enhance interdisciplinary communication and care. DISCUSSION: Beginning in 2015, there was a proliferation of articles about PC and EHRs, suggesting increasing incorporation of and research about the EHR with PC. This review indicates the EHR is underutilized for PC CDS, facilitating PROMs, and capturing ACPs.

RESUMO

BACKGROUND: Little is known about the health care utilization patterns of individuals with pediatric autism spectrum disorder (ASD). OBJECTIVES: Electronic health record (EHR) data provide an opportunity to study medical utilization and track outcomes among children with ASD.  Methods: Using a pediatric, tertiary, academic hospital's Epic EHR, search queries were built to identify individuals aged 2-18 with International Classification of Diseases, Ninth Revision (ICD-9) codes, 299.00, 299.10, and 299.80 in their records. Codes were entered in the EHR using four different workflows: (1) during an ambulatory visit, (2) abstracted by Health Information Management (HIM) for an encounter, (3) recorded on the patient problem list, or (4) added as a chief complaint during an Emergency Department visit. Once individuals were identified, demographics, scheduling, procedures, and prescribed medications were extracted for all patient-related encounters for the period October 2010 through September 2012. RESULTS: There were 100,000 encounters for more than 4,800 unique individuals. Individuals were most frequently identified with an HIM abstracted code (82.6%) and least likely to be identified by a chief complaint (45.8%). Categorical frequency for reported race (2 = 816.5, p < 0.001); payor type (2 = 354.1, p < 0.001); encounter type (2 = 1497.0, p < 0.001); and department (2 = 3722.8, p < 0.001) differed by search query. Challenges encountered included, locating available discrete data elements and missing data. CONCLUSIONS: This study identifies challenges inherent in designing inclusive algorithms for identifying individuals with ASD and demonstrates the utility of employing multiple extractions to improve the completeness and quality of EHR data when conducting research.

RESUMO

The patient portal, increasingly available to patients, allows secure electronic communication with physicians. Although physician attitude toward the portal plays a crucial role in patient adoption, little information regarding physician opinion of the portal is available, with almost no information gathered in the pediatric environment. Using a mixed-methods approach, physicians in a large pediatric medical facility and integrated delivery network were surveyed using an online quantitative questionnaire and structured interviews. Physicians reported the portal's role in more communication efficiency for patients, parents, and providers. The portal's acceptance also introduces new challenges such as frequent questions from some parents and medical visit avoidance.

RESUMO

BACKGROUND: This study assessed the current state of knowledge regarding the use of the integrated electronic health record (EHR) patient portal for pediatric clinical care. A systematic examination of the research on implementation, utilization, and evaluation of the integrated EHR patient portal among pediatric patients has not been previously conducted. Therefore, the purpose of the present study was to systematically review existing research on the state of the science, describe the way others have defined the patient portal, and examine pediatric patient portal utilization. MATERIALS AND METHODS: Covering a period from 1992 to 2014 a literature search was conducted on four electronic databases. Only articles in English were reviewed. Studies were included if they reported the use of a patient portal integrated with an electronic health record and captured pediatric medial encounters. Qualitative or quantitative studies of any design were eligible as long as they focused on patients (or parents) who access their health records through an electronic portal tied to an EHR and reported measures of satisfaction, attitudes on use, barriers and facilitators, adherence, or clinical and health outcomes. Content analysis of each article was performed independently by at least two authors using an extraction grid of study qualities, and quality and relevance of the studies were also assessed. RESULTS: Of a total of 189 potentially relevant publications identified, 31 full-text publications were obtained after screening titles and abstracts. After a full review, 11 publications corresponding to seven studies met the inclusion criteria. The methodological approaches included cross-sectional surveys, retrospective analysis, qualitative studies, and usability testing. In general, feedback was positive. The most frequent negative comments about the portal reflected concern about teenager interaction with the portal and how that might affect communication among patient, parent, and provider. Some users were frustrated with the complexity of medical terminology used. CONCLUSIONS: Reflecting the additional considerations of pediatric proxy access and fewer chronically ill patients, pediatric medicine has yet to use the patient portal as a modality for outcomes measurement. Given the paucity of studies within this age group, it is difficult to measure outcome improvements or the effect of patient record access on healthcare behaviors. This systematic review presents innovative research on the general acceptance of the patient portal among parents and highlights that the implementation of the portal is still in its early stages and has yet to be used widely in diverse populations or studies in a longitudinal manner. Further studies should confirm that protected access to health information and secure communication and information sharing with healthcare providers have an impact in the pediatric population on healthcare outcomes.
