Usefulness of the Diagnosis "Decreased Cardiac Output (00029)" in Patients With Chronic Heart Failure

Using Principles of Digital Development for a Smartphone App to Support Data Collection in Patients With Acute Myocardial Infarction and Physical Activity Intolerance: Case Study

BACKGROUND

Advances in health have highlighted the need to implement technologies as a fundamental part of the diagnosis, treatment, and recovery of patients at risk of or with health alterations. For this purpose, digital platforms have demonstrated their applicability in the identification of care needs. Nursing is a fundamental component in the care of patients with cardiovascular disorders and plays a crucial role in diagnosing human responses to these health conditions. Consequently, the validation of nursing diagnoses through ongoing research processes has become a necessity that can significantly impact both patients and health care professionals.

OBJECTIVE

We aimed to describe the process of developing a mobile app to validate the nursing diagnosis "intolerance to physical activity" in patients with acute myocardial infarction.

METHODS

We describe the development and pilot-testing of a mobile system to support data collection for validating the nursing diagnosis of activity intolerance. This was a descriptive study conducted with 11 adults (aged ≥18 years) who attended a health institution for highly complex needs with a suspected diagnosis of coronary syndrome between August and September 2019 in Floridablanca, Colombia. An app for the clinical validation of activity intolerance (North American Nursing Diagnosis Association [NANDA] code 00092) in patients with acute coronary syndrome was developed in two steps: (1) operationalization of the nursing diagnosis and (2) the app development process, which included an evaluation of the initial requirements, development and digitization of the forms, and a pilot test. The agreement level between the 2 evaluating nurses was evaluated with the κ index.

RESULTS

We developed a form that included sociodemographic data, hospital admission data, medical history, current pharmacological treatment, and thrombolysis in myocardial infarction risk score (TIMI-RS) and GRACE (Global Registry of Acute Coronary Events) scores. To identify the defining characteristics, we included official guidelines, physiological measurements, and scales such as the Piper fatigue scale and Borg scale. Participants in the pilot test (n=11) had an average age of 63.2 (SD 4.0) years and were 82% (9/11) men; 18% (2/11) had incomplete primary schooling. The agreement between the evaluators was approximately 80% for most of the defining characteristics. The most prevalent characteristics were exercise discomfort (10/11, 91%), weakness (7/11, 64%), dyspnea (3/11, 27%), abnormal heart rate in response to exercise (2/10, 20%), electrocardiogram abnormalities (1/10, 9%), and abnormal blood pressure in response to activity (1/10, 10%).

CONCLUSIONS

We developed a mobile app for validating the diagnosis of "activity intolerance." Its use will guarantee not only optimal data collection, minimizing errors to perform validation, but will also allow the identification of individual care needs.

Decreased cardiac output: an integrative review

OBJECTIVE

to identify, in the scientific literature, the defining characteristics and contributing factors (related factors, associated conditions and populations at risk) for nursing diagnosis decreased cardiac output.

METHOD

an integrative literature review, conducted between September and October 2020, with an update in March 2022, in the MEDLINE via PubMed, LILACS, SciELO, CINAHL and EMBASE databases. Using acronym PEO, studies published in the last 10 years in Portuguese, English and Spanish were included. A descriptive analysis was carried out to present the elements mapped in the literature.

RESULTS

analysis of 31 articles identified different elements, highlighting 4 new related factors: hyperglycemic stress, prone position, left lateral position, sleep deprivation. Individuals with a history of cardiovascular disease and males were identified as possible populations at risk.

FINAL CONSIDERATIONS

the elements for decreased cardiac output, identified in the literature, add evidence that justifies the permanence of this diagnosis in the NANDA-I classification.

Cross-mapping of nursing diagnoses and interventions in decompensated heart failure

OBJECTIVE

To map the terms recorded in medical records of patients with decompensated heart failure for nursing diagnoses and interventions from the NANDA International and Nursing Interventions Classification.

METHOD

This is an exploratory and descriptive research, carried out by a cross-mapping study. Data were collected from 107 medical records of a Hospital Institute in the city of Rio de Janeiro/Brazil, in a period between October 2017 to February 2019. The diagnoses and interventions mapped were assessed by four clinical experts. Data analysis was performed using the content validation index and the Fleiss Kappa.

RESULTS

The most frequent nursing diagnoses were: risk for infection (74.8%), decreased cardiac output (55.1%) and excessive fluid volume (49.5%). The interventions were: vital signs monitoring (79.4%), fluid monitoring (72.9%) and positioning (52.3%).

CONCLUSION

The research mapped 32 titles of nursing diagnoses from NANDA-I and 21 nursing interventions from NIC. The diagnoses and interventions mapped will contribute to the quality of the nurses' records and patient safety.

Validación de constructo de la escala Zung en pacientes con falla cardíaca

Introducción: La escala Zung para depresión ha sido previamente utilizada en pacientes con falla cardíaca; sin embargo, en nuestro conocimiento no se encuentra evidencia de su validez para la versión en español y su uso en población adulta con falla cardíaca en Colombia. Objetivo: Determinar la validez de constructo de la escala Zung para depresión en su versión original y proponer una versión abreviada para pacientes adultos con falla cardíaca. Materiales y Métodos: Estudio de corte transversal, realizado en 200 pacientes de una clínica de falla y trasplante cardiaco, en quienes se aplicó Zung Self-Rating Depression Scale. Se evaluó la consistencia interna por medio del alfa de Cronbach y el  análisis factorial fue utilizado para identificar las dimensiones del instrumento. Resultados: La consistencia interna de la versión original de la escala (20 ítems) fue de α=0.811. El análisis de factores mostró una estructura compuesta por tres factores que explican el 51.59% de la varianza total. La nueva versión abreviada (13 ítems) obtuvo un α=0.819 y los ítems correlacionaron con un único factor que explicó el 33.54% de la varianza total. Discusión: Nuestros hallazgos son similares a los encontrados por otros autores en diferentes poblaciones a la estudiada. Conclusiones: Se evidenció validez de constructo tanto para la escala Zung para depresión en su versión original como para la abreviada creada en la población estudiada. Sin embargo, se requieren estudios adicionales que verifiquen estos hallazgos en una muestra representativa y que otros aspectos de la psicometría sean evaluados.

Nursing Diagnoses of hospitalized patients with heart failure: a longitudinal study

OBJECTIVE

Identifying Nursing Diagnoses of fatigue, activity intolerance and decreased cardiac output in hospitalized patients with heart failure and verifying the association between the defining characteristics and the Nursing Diagnoses.

METHOD

A longitudinal and prospective study that followed hospitalized patients with heart failure for three weeks. The data collected through interviews and physical examinations were sent to expert nurses for diagnostic inference. Descriptive and inferential statistical analyses were carried out.

RESULTS

Of the 72 patients, 68.0% were male and presented the nursing diagnosis of decreased cardiac output (62.5%) in the first week, reducing to 52.8% and 38% in the second and third weeks, respectively. Fatigue only appeared in one patient. Activity intolerance was the diagnosis that had the greatest discrepancy among the experts. Decreased cardiac output was associated to the defining characteristics: dyspnea, edema, jugular venous distension and reduced ejection fraction during all three weeks of evaluation.

CONCLUSION

Decreased cardiac output was more prevalent in hospitalized patients with heart failure, and the associated defining characteristics were determining factors for this nursing diagnosis.

OBJETIVO

Identificar os diagnósticos de enfermagem fadiga, intolerância à atividade e débito cardíaco diminuído em pacientes com insuficiência cardíaca hospitalizados e verificar a associação entre as características definidoras e os diagnósticos de enfermagem.

MÉTODO

Estudo longitudinal e prospectivo que acompanhou pacientes com insuficiência cardíaca hospitalizados por três semanas. Os dados coletados por entrevista e exame físico foram encaminhados a enfermeiros peritos para inferência diagnóstica. Realizou-se análise estatística descritiva e inferencial.

RESULTADOS

Dos 72 pacientes, 68,0% eram do sexo masculino e apresentaram o diagnóstico de enfermagem débito cardíaco diminuído (62,5%) na primeira semana, reduzindo para 52,8% e 38% na segunda e terceira semana, respectivamente. Fadiga apareceu somente em um paciente. Intolerância à atividade foi o diagnóstico que teve maior discordância entre os peritos. Débito cardíaco diminuído foi associado às características definidoras dispneia, edema, distensão da veia jugular e fração de ejeção diminuída nas três semanas de avaliação.

CONCLUSÃO

Débito cardíaco diminuído esteve mais prevalente em pacientes com insuficiência cardíaca hospitalizados, sendo as características definidoras associadas determinantes para este diagnóstico de enfermagem.
