Prognostic Indicators of Delayed Surgical Recovery in Patients Undergoing Cardiac Surgery.

PURPOSE: The purpose of this study was to analyze the prognostic capacity of the clinical indicators of a delayed surgical recovery nursing diagnosis throughout the hospital stay of patients having cardiac surgery. DESIGN: A prospective cohort design was adopted. A sample of inpatients undergoing elective cardiac surgery was followed during the immediate preoperative period and hospitalization. This research was conducted in the southeast region of Brazil at a national reference institution that treats highly complex diseases and performs cardiac surgeries. Data were collected from July 2017 to July 2018. METHODS: At the end of 1 year of data collection, 181 patients were followed in this study. The Kaplan-Meier method was used to calculate the survival time related to delayed surgical recovery. In addition, an extended Cox model of time-dependent covariates was adjusted to identify the clinical signs that influenced the change in the nursing diagnosis status. RESULTS: A delayed surgical recovery nursing diagnosis was present in 23.2% of the sample studied. With an expected length of stay of 8 to 10 days, most new cases of delayed surgical recovery were observed on the 10th postoperative day, and the survival rate after this day was decreased until the 29th postoperative day, when the nursing diagnosis no longer appeared. Interrupted healing of the surgical area, loss of appetite, and atrial flutter were indicators related to an increased risk for delayed surgical recovery. CONCLUSIONS: Timely recognition of selected clinical indicators demonstrates a promising prognostic capacity for delayed surgical recovery. CLINICAL RELEVANCE: Accurate identification of prognostic factors allows nurses to identify early signs of postoperative complications. Consequently, the professional can develop an individualized plan of care, aiming at the satisfactory clinical recovery of the patient.

The factors related to a sedentary lifestyle: A meta-analysis review.

AIMS: To compare factors associated with the sedentary lifestyle described in the literature with the factors listed in NANDA International. DESIGN: Systematic review with meta-analysis of factors associated with a sedentary lifestyle in adolescents, adults and older people. DATA SOURCES: An electronic search of PubMed, Scopus, CINAHL and Latin America and the Caribbean Literature on Health and Science databases conducted in May 2016. REVIEW METHODS: Descriptive data were extracted according to a standardized form. The odds ratios for each etiological factor associated with a sedentary lifestyle were extracted directly from the articles or calculated from the data described therein. The meta-analysis was conducted for factors that were investigated in more than one study. RESULTS: Thirty-five articles were included. The statistically significant factors were: lack of social support, of physical space, of time, of motivation, of sports skills and of interest in physical activity, intolerance to activity, being retired, living in a low-income country, laziness, not having a job/studying, low socioeconomic status and level of knowledge about physical activity, female gender, living in an urban area, negative self-perception of health, using public transportation, being in the oldest age group in the study and perceived physical disability. CONCLUSION: The new factors associated with a sedentary lifestyle and those already included in the NANDA International classification will lead to better clinical guidance for nurses. IMPACT: Knowledge about these factors can contribute directly to public health policies.

Clinical indicators and aetiological factors of sedentary lifestyle in patients with arterial hypertension.

AIMS: The aim of this study is to verify the clinical validity of clinical indicators and aetiological factors of sedentary lifestyle in individuals with arterial hypertension. BACKGROUND: Diagnostic validation is performed to expand nursing taxonomies and to revise or confirm the described concepts. New elements listed in the literature and those identified by the NANDA International definition for sedentary lifestyle need to be evaluated. DESIGN: This is a cross-sectional and diagnostic validation study. The STROBE guidelines were used in this study. METHODS: Two hundred and fifty subjects aged over 18 years were evaluated. The diagnostic status of the participants was obtained by latent class analysis. Logistic regression was used to identify aetiological factors with the manifestation of sedentary lifestyle, considering a significance level of 5%. RESULTS: A total of 57.8% of the study participants met the diagnostic criteria for sedentary lifestyle. The clinical indicators with high sensitivity were as follows: "Average daily physical activity is less than recommended for gender and age"; "Does not perform physical activity during leisure time"; "Preference for activity low in physical activity" and "Overweight." The significantly related factors associated with the diagnosis of sedentary lifestyle were as follows: "Insufficient knowledge on physical activity," "Lack of time," "Negative self-perception of health," "Lack of security," "Lack of appropriate place," "Lack of motivation," "Activity intolerance," "Lack of sports ability," "Having a partner," "Using public transportation," "Perception of physical disability," "Pain," "Having a job/studying," "Laziness," "Impaired mobility," "Living in an urban area," "Education in a public institution," "Female gender," "Lack of confidence to practice physical exercise," "Education level," "Age" and "Lack of social support for the practice of physical exercise." CONCLUSION: Four out of eight clinical indicators had a good adjustment by the latent class analysis. Of the 27 aetiological factors, 22 were significantly associated with sedentary lifestyle. RELEVANCE TO PRACTICE: The correct identification of sedentary lifestyle and its elements supports care planning, especially for health promotion and disease prevention.

A Content Analysis of Clinical Indicators and Etiological Factors of Ineffective Infant Feeding Patterns.

PURPOSE: To analyze the content of the concepts present in the nursing diagnosis of Ineffective infant feeding pattern. DESIGN AND METHODS: Content validation of nursing diagnosis based on the predictive diversity model. A methodological study of the content validation of a nursing diagnosis was based on the predictive diversity model and performed in the following three stages: conceptual definition of the phenomenon of interest; organization of the phenomenon of interest; and analysis by judges of the concepts of the phenomenon of interest. RESULTS: The first two stages identified 13 clinical indicators and 12 etiological factors, which were evaluated by 23 judges. The analyses of judgments were performed according to the level of expertise of the judges. All the clinical indicators were relevant to nursing diagnosis under study. Nine causal factors were analyzed, including the level of importance to the occurrence of Ineffective infant feeding pattern. CONCLUSIONS: This study analyzed the diagnostic structure of Ineffective infant feeding pattern, which were considered representative of the phenomenon of interest after evaluation by the judges. PRACTICE IMPLICATIONS: The use of nursing diagnosis with accurate elements facilitates clinical reasoning and favors the development of an adequate care plan.

Validation of Clinical Indicators of Imbalanced Nutrition: Less Than Body Requirements in Early Childhood.

This is a clinical validation study of the nursing diagnosis of imbalanced nutrition: less than body requirements based on the diagnostic accuracy measures. Measures of sensitivity and specificity were calculated based on the latent class analysis method using a random effects model in a sample of 123 children between 0 and 6 years old. The prevalence of the diagnosis was estimated to be 27.6% using the latent class model. Indicators that exhibited the best measures of diagnostic accuracy included insufficient interest in food and satiety immediately upon ingesting food. A total of seven clinical indicators were validated clinically.

Clinical validation of the NANDA-I diagnosis of impaired memory in elderly patients.

PURPOSE: The aim of this study was to perform a clinical validation of the defining characteristics of impaired memory (IM) in elderly patients at a long-term care institution. METHODS: A sample of 123 elderly patients was evaluated with a questionnaire designed to identify IM according to the NANDA-I taxonomy. Accuracy measures were calculated for the total sample and for males and females separately. RESULTS: Sensitivity and specificity values indicated that: (1) inability to learn new skills is useful in screening IM, and (2) forgets to perform a behavior at a scheduled time, forgetfulness, inability to learn new information, inability to recall events, and inability to recall factual information are confirmatory indicators. CONCLUSION: Specific factors can affect the manifestation of IM by elderly patients. The results may be useful in improving diagnostic accuracy and efficiency of the IM nursing diagnosis.

Diagnostic accuracy of clinical indicators of Imbalanced nutrition in pediatric patients submitted to chemotherapy.

To analyze the accuracy of clinical indicators of nursing diagnosis, Imbalanced nutrition: less than the body requirements in pediatric patients undergoing chemotherapy. A cross-sectional study was carried out in a pediatric oncohematology unit. A total of 123 children aged 5-18 years were evaluated. The Standards for Reporting Diagnostic Accuracy Studies (STARD) protocol was used. Latent class analysis was performed to obtain sensitivity and specificity of clinical indicators. The diagnosis was identified in six children (5.23%). The most frequent clinical indicator in the study was report of food intake less than recommended daily allowance (n = 61; 49.6%), followed by excessive hair loss (n = 49; 39.8%), misperception (n = 42; 34.1%), satiety immediately upon ingesting food (n = 32; 26%), lack of information (n = 30; 24.4%), and pale mucous membranes (n = 22; 17.9%). The 10 indicators that sensitivity and specificity were statistically superior to 50% were food intake less than recommended daily allowance, misperception, insufficient interest in food, lack of food, hyperactive bowel sounds, body weight 20% or more below ideal weight range, insufficient muscle tone, food aversion, abdominal cramping, and misinformation. The clinical indicators Food intake less than recommended daily allowance and Misperception can be considered the most important indicators for the initial inference of the diagnosis due to their high values of specificity and sensitivity. It is essential that nurses provide targeted and qualified assistance based on the signs and symptoms presented by patients, as they will be able to design appropriate interventions to obtain the desired results.

Simultaneous concept analysis of nursing diagnoses related to respiratory function.

AIM: To perform a simultaneous concept analysis of the concepts associated to nursing diagnoses ineffective airway clearance, ineffective breathing pattern, and impaired gas exchange. BACKGROUND: Concepts about respiratory manifestations need to be well defined, especially in the current pandemic scenario. For that, the simultaneous concept analysis can help in the clarity and differentiation of similar concepts. METHODS: A concept analysis using the Walker and Avant approach and an integrative review. Data were collected by a group of nurses through a literature review. The group identified 10 articles that met the inclusion criteria and complemented the understanding of the concepts analysed through the sequential description of respiratory physiology in technical books. RESULTS: The final list included 28, 22, and 21 clinical indicators for ineffective breathing pattern, impaired gas exchange, and ineffective airway clearance, respectively. The former, the final proposal incorporated 13 indicators that were pointed out by the group and 15 defining characteristics of NANDA-International. For Impaired gas exchange, the indicator "decreased oxygen saturation" was included; among the defining characteristics of NANDA-International, "abnormal arterial blood gases" was excluded, and "abnormal breathing pattern" was subdivided into "alterations in respiratory depth," "bradypnea," "tachypnea," and "change in respiratory rhythm." The latter, only the "wide-eyed" was removed from the final list of clinical indicators, which subsequently consisted of nine indicators suggested by the group and 12 defining characteristics. CONCLUSION: This concept analysis may aid in the process of differentiation for ineffective airway clearance, ineffective breathing pattern, and impaired gas exchange, and aid in safer diagnostic inference. This concept analysis can support the understanding of respiratory nursing diagnoses, helping nurses to identify and differentiate them more safely.

Nutritional Deficits In Children With Cancer: A Situation-Specific Theory.

PURPOSE: To construct a situation-specific theory (SST) to represent nutritional deficits for assessing children with cancer. DATA SOURCES: Literature review. DATA SYNTHESIS: The SST included the definition of key concepts, a pictorial scheme, propositions, causal relationships, and evidence for nursing practice. CONCLUSIONS: It was possible to characterize the elements as antecedent and consequent clinical factors to allow for an understanding of the existing relationships between them and their temporality. These elements differed considerably from those included in NANDA International. IMPLICATIONS FOR NURSING PRACTICE: This study provides additional information so that nurses in clinical practice can infer the presence of nutritional deficits in children with cancer early, given the risk already inherent in the diagnosis of cancer and treatment.

A Middle-Range Theory for Nurses to Diagnose Ineffective Infant Feeding Patterns.

PURPOSE: To construct a middle-range theory, based on the Roy adaptation model, for nurses can diagnose an ineffective infant feeding pattern. DATA SOURCE: Scientific findings were used through a literature review and the concepts of the Roy model. DATA SYNTHESIS: The theory indicated new elements for the diagnosis: 12 etiological factors and 13 clinical indicators. Most of those are not contained in the NANDA taxonomy. CONCLUSION: The middle-range theory for these diagnoses highlights the need for a review of the components present in the taxonomy. IMPLICATIONS FOR NURSING PRACTICE: This approach guides research on nursing diagnoses to revise the content of the theory and to expand its concepts and elements for the diagnosis of an ineffective infant feeding pattern.

A Content Analysis of Clinical Indicators of the Nursing Diagnosis Ineffective Breathing Pattern.

PURPOSE: To verify the relevance of the clinical indicators, the clarity and precision of the conceptual, and operational definitions for Ineffective breathing pattern (IBP). METHODS: A content analysis by 39 judges. FINDINGS: The results showed 28 clinical indicators for IBP. However, only seven were not considered relevant for the diagnosis. These are not listed in NANDA International taxonomy. All conceptual and operational definitions were adequate, according to the analysis of the judges. CONCLUSION: The list of 28 clinical indicators of IBP was submitted for analysis by judges, which then resulted in the validation of 21 of these elements. IMPLICATIONS FOR NURSING PRACTICE: This study clarifies that gaps in the structure of diagnoses, helping nurses' diagnostic reasoning process in clinical practice.

Unidimensional analysis of the nursing diagnoses of situational low self-esteem and chronic low self-esteem.

PURPOSE: To analyze the unidimensionality of the nursing diagnoses low situational self-esteem and low chronic self-esteem proposed by NANDA-I. DESING AND METHODS: Diagnostic accuracy study carried out with 180 patients with depressed mood in a psychiatric hospital in northeastern Brazil. FINDINGS: The analysis of the latent class considered the hypothesis of low self-esteem as a unique construct and included the indicators: Excessive seeking of reassurance, repeatedly unsuccessfulness in life events, rejection of positive feedback, insomnia, solitude, and nonassertive behavior. PRACTICE IMPLICATIONS: The recognition of low self-esteem as a unique diagnostic construct allows nurses to be more assertive in the provision of care.

Content analysis of clinical indicators for Impaired gas exchange.

OBJECTIVE: To analyze the relevance of clinical indicators and the clarity and precision of conceptual and operational definitions of the diagnosis Impaired gas exchange. METHODS: Content analysis, by 39 nurse judges, divided into the phases of conceptual definition of the phenomenon of interest, construction of the structure of the phenomenon of interest and analysis of the judges on the built structure. RESULTS: From the 22 indicators, 21 were considered relevant Impaired gas exchange. The indicators that obtained absolute relevance were Cyanosis, Hypercapnia, Hypoxemia and Tachycardia. The indicator Headache upon waking did not show any statistically significant relevance for the diagnosis. All conceptual and operational definitions were clear and precise. CONCLUSION: The indicators listed for Impaired gas exchange were relevant to the phenomenon, except Headache upon waking because it does not correspond to a safe manifestation to identify the diagnosis, according to the analysis of the judges. Each conceptual and operational definition was adequate for its indicator.

Pentacam Scheimpflug evaluation of corneal volume after LASIK.

PURPOSE: To assess the change in corneal volume and laser ablation volume over time after LASIK using a rotating Scheimpflug camera. METHODS: Twenty-six patients (49 eyes) underwent LASIK. Pentacam Scheimpflug measurements were performed pre- and postoperatively at 1, 3, 7, 15, and 30 days. Central corneal thickness, total corneal volume (10-mm diameter), and partial corneal volumes (3, 5, and 7 mm) based on the apex of the cornea, were measured. Main outcome measures were differences between pre- and postoperative volume measurements of total and partial corneal regions, volume changes over time postoperatively, and comparison between laser ablation volume and corneal volume. RESULTS: A strong linear relationship was noted between spherical equivalent refraction and laser ablation volume (r = -0.931, P < .0001). Furthermore, 30 days after LASIK, a strong linear relationship was noted between planned thickness and achieved thickness (r = 0.9457, P < .001). Corneal volumes for 3-, 5-, and 7-mm diameter regions significantly decreased over time postoperatively (one-way analysis of variance, P < .05). CONCLUSIONS: Alterations in corneal volume correlated with laser ablation volume when the diameter of the region considered was 3, 5, or 7 mm from the corneal apex.

Principais motivos de descarte de córneas para transplante na Paraíba: por que o anti-HBc merece atenção?* / Main reasons for discarding corneas for transplant in Paraíba: why does anti-HBc deserve attention?*

RESUMO Objetivo: Identificar o perfil dos doadores de tecidos oculares humanos na área de atuação do Banco de Olhos da Paraíba, destacando o impacto da sorologia positiva para hepatite B no descarte dos tecidos para transplante. Métodos: O estudo é transversal e utilizou dados do Banco de Olhos da Paraíba entre janeiro de 2013 e dezembro de 2022. Dados sobre procedência, idade, sexo, causa do óbito, tempo entre óbito e enucleação, resultados sorológicos e motivo de descarte das córneas dos doadores foram coletados. Resultados: O maior motivo de descarte foi por sorologia positiva (56,5%), sendo positivadas as sorologias positivas para hepatite B e HBsAg em 11,1% e 4,75% dos pacientes, respectivamente. Conclusão: A sorologia positiva para hepatite B como um critério de descarte absoluto é responsável por grande parcela de descartes, apesar da pouca informação sobre suas repercussões e representação de infectividade nos receptores do transplante.

ABSTRACT Objective: To identify the profile of human ocular tissue donors in the area covered by the Eye Bank of Paraíba (PB), highlighting the impact of positive serology for hepatitis B (anti-HBc) in the disposal of tissues for transplantation. Methods: This is a cross-sectional that uses data from the Eye Bank of Paraíba (PB) between January 2013 and December 2022. Data on origin, age, sex, cause of death, time between death and enucleation, serological results, and reason for discarded donor corneas were collected. Results: The main reason for discarding was due to positive serology (56.5%), with positive anti-HBc and HBsAg serology in 11.1% and 4.75% of patients, respectively. Conclusion: Anti-HBc positive serology as an absolute disposal criterion is responsible for great part of disposals, despite little information about its repercussions and representation of infectivity in transplant recipients.

RESULTS: Concordance ratio >0.8 for all propositions related to design, practicality and most of the propositions related to error prevention. CONCLUSION: According to the opinion of the nursing team, the implemented technology has an adequate design, as well as being practical and useful in the prevention of medication errors in the population at the ICU.

Wide distribution of Trypanosoma cruzi-infected triatomines in the State of Bahia, Brazil.

BACKGROUND: The identification of Trypanosoma cruzi and blood-meal sources in synanthropic triatomines is important to assess the potential risk of Chagas disease transmission. We identified T. cruzi infection and blood-meal sources of triatomines caught in and around houses in the state of Bahia, northeastern Brazil, and mapped the occurrence of infected triatomines that fed on humans and domestic animals. METHODS: Triatominae bugs were manually captured by trained agents from the Epidemiologic Surveillance team of Bahia State Health Service between 2013 and 2014. We applied conventional PCR to detect T. cruzi and blood-meal sources (dog, cat, human and bird) in a randomized sample of triatomines. We mapped triatomine distribution and analyzed vector hotspots with kernel density spatial analysis. RESULTS: In total, 5906 triatomines comprising 15 species were collected from 127 out of 417 municipalities in Bahia. The molecular analyses of 695 triatomines revealed a ~10% T. cruzi infection rate, which was highest in the T. brasiliensis species complex. Most bugs were found to have fed on birds (74.2%), and other blood-meal sources included dogs (6%), cats (0.6%) and humans (1%). Trypanosoma cruzi-infected triatomines that fed on humans were detected inside houses. Spatial analysis showed a wide distribution of T. cruzi-infected triatomines throughout Bahia; triatomines that fed on dogs, humans, and cats were observed mainly in the northeast region. CONCLUSIONS: Synanthropic triatomines have a wide distribution and maintain the potential risk of T. cruzi transmission to humans and domestic animals in Bahia. Ten species were recorded inside houses, mainly Triatoma sordida, T. pseudomaculata, and the T. brasiliensis species complex. Molecular and spatial analysis are useful to reveal T. cruzi infection and blood-meal sources in synanthropic triatomines, identifying areas with ongoing threat for parasite transmission and improving entomological surveillance strategies.

Nursing diagnoses associated with the national policy for health promotion.

OBJECTIVES: To identify the relationships between nursing diagnoses proposed by NANDA-I taxonomy II and the priority themes (PT) of the National Policy for Health Promotion (PNPS in Portuguse). METHODS: An integrative literature review was carried out in the Scopus, Cinahl and SciELO databases, using the descriptors: health promotion, food habits, traffic accidents, drugs abuse, environment and public health. The search considered scientific articles published between 2000 and 2016. RESULTS: Twelve articles were selected to identify and explore nursing actions related to PT. It was identified that although the said taxonomy offers a Domain called Health promotion, there is a need to relate the diagnoses of other domains to include the health actions described in the aforementioned Policy. It was observed that there is an attention and concern of the nursing professionals to address topics such as the training of managers and the promotion of healthy eating. In relation to the priority themes promotion of safe mobility and sustainable development, no nursing diagnoses were identified due to the scarcity of diagnoses related to them in the mentioned taxonomy. CONCLUSIONS: Although the NANDA-I taxonomy presents a specific domain on health promotion, these are not sufficient to meet the needs of the priority themes proposed by PNPS.

The construction and evaluation of new educational software for nursing diagnoses: a randomized controlled trial.

BACKGROUND: Student nurses often have difficulties with diagnostic inferences. To achieve high accuracy nursing diagnoses, effective learning strategies are required. OBJECTIVE: To describe the construction and evaluation of new educational software called Wise Nurse, which was developed to increase the capacity of student nurses to identify nursing diagnoses (NDx) and to establish relationships between NDx, defining characteristics (DC), and related factors (RF). DESIGN: Randomized controlled trial. SETTING AND PARTICIPANTS: Participants were 2nd to 4th year student nurses from an undergraduate program at a university in Brazil. Of the 47 recruited students, 37 completed the survey. METHODS: Students were randomly assigned to test the software (experimental group) and to solve printed clinical cases (comparison group). A pretest and post-test were applied before and after the experiment. Statistical analyses of the students' performance in the tests were conducted. The primary outcome was the students' progress in solving questions and clinical cases regarding NDx. The System Usability Scale was used to measure the software's ease of use. RESULTS: No significant difference was found between the experimental and comparison groups before and after the experiment. The average students' performance in identifying RF and NDx was higher than in identifying DC. The post-test score was higher than the pretest score in both groups (P=0.022). The usability score was good (average score 83.75, N=20). CONCLUSION: The use of Wise Nurse supported an improvement in student diagnostic reasoning equivalent to that of the traditional NDx training, but the software stands out as an innovative teaching tool.
