Diagnostic reliability of an immunochromatographic test for Chagas disease screening at a primary health care centre in a rural endemic area

Many patients with Chagas disease live in remote communities that lack both equipment and trained personnel to perform a diagnosis by conventional serology (CS). Thus, reliable tests suitable for use under difficult conditions are required. In this study, we evaluated the ability of personnel with and without laboratory skills to perform immunochromatographic (IC) tests to detect Chagas disease at a primary health care centre (PHCC). We examined whole blood samples from 241 patients and serum samples from 238 patients. Then, we calculated the percentage of overall agreement (POA) between the two groups of operators for the sensitivity (S), specificity (Sp) and positive (PPV) and negative (NPV) predictive values of IC tests compared to CS tests. We also evaluated the level of agreement between ELISAs and indirect haemagglutination (IHA) tests. The readings of the IC test results showed 100% agreement (POA = 1). The IC test on whole blood showed the following values: S = 87.3%; Sp = 98.8%; PPV = 96.9% and NPV = 95.9%. Additionally, the IC test on serum displayed the following results: S = 95.7%; Sp = 100%; PPV = 100% and NPV = 98.2%. Using whole blood, the agreement with ELISA was 96.3% and the agreement with IHA was 94.1%. Using serum, the agreement with ELISA was 97.8% and the agreement with IHA was 96.6%. The IC test performance with serum samples was excellent and demonstrated its usefulness in a PHCC with minimal equipment. If the IC test S value and NPV with whole blood are improved, then this test could also be used in areas lacking laboratories or specialised personnel.

Viral aetiology of common colds of outpatient children at primary care level and the use of antibiotics

Although antibiotics are ineffective against viral respiratory infections, studies have shown high rates of prescriptions worldwide. We conducted a study in Brazil to determine the viral aetiologies of common colds in children and to describe the use of antibiotics for these patients. Children up to 12 years with common colds were enrolled from March 2008-February 2009 at a primary care level facility and followed by regular telephone calls and medical consultations. A nasopharyngeal wash was obtained at enrollment and studied by direct fluorescence assay and polymerase chain reaction for nine different types of virus. A sample of 134 patients was obtained, median age 2.9 years (0.1-11.2 y). Respiratory viruses were detected in 73.9% (99/134) with a coinfection rate of 30.3% (30/99). Rhinovirus was the most frequent virus (53/134; 39.6%), followed by influenza (33/134; 24.6%) and respiratory syncytial virus (8/134; 13.4%). Antibiotic prescription rate was 39.6% (53/134) and 69.8% (37/53) were considered inappropriate. Patients with influenza infection received antibiotics inappropriately in a greater proportion of cases when compared to respiratory syncytial virus and rhinovirus infections (p = 0.016). The rate of inappropriate use of antibiotics was very high and patients with influenza virus infection were prescribed antibiotics inappropriately in a greater proportion of cases.

Atitudes dos enfermeiros face à família: validação da escala Families' Importance in Nursing Care - Nurses Attitudes

As atitudes que os enfermeiros adotam em relação à família condicionam o processo de cuidar. Nosso propósito com este estudo foi nesse sentido: dispor de um instrumento que nos permitisse conhecer esta variável. Assim, nossa proposta foi efetuar a adaptação transcultural e avaliar as propriedades psicométricas da versão portuguesa do instrumento Families' Importance in Nursing Care - Nurses Attitudes (FINC-NA), que visa avaliar as atitudes dos enfermeiros acerca da importância de envolver a família nos cuidados de enfermagem. Foi seguido o método preconizado pela literatura. A amostra foi constituída por 136 enfermeiros dos Cuidados de Saúde Primários. Os resultados obtidos nos testes de confiabilidade revelam uma boa consistência interna para o total dos itens (Alpha de Cronbach = 0,87). O estudo psicométrico permite-nos afirmar que a versão em português da FINC-NA, que denominamos A importância das famílias nos cuidados de enfermagem - atitudes dos enfermeiros (IFCE-AE), é um instrumento fidedigno e válido.

Dignity in care: where next for nursing ethics scholarship and research?

Dignity is recognised as both a central and also a contested value in bioethics discourse. The aim of this manuscript is to examine some of the key strands of the extensive body of dignity scholarship and research literature as it relates to nursing ethics and practice. The method is a critical appraisal of selected articles published in Nursing Ethics and other key manuscripts and texts identified by researchers in the UK and Brazil as influential. The results suggest a wide and rather confusing range of perspectives and findings albeit with some overall themes relating to objective and subjective features of dignity. In conclusion, the authors point to the need for more sustained philosophical engagement contextualising human dignity within a plurality of professional values. Future empirical work should explore what matters to patients, families, professionals and citizens in different cultural contexts rather than foregrounding qualitative research with such a contested concept.

Care in a birth center according to the recommendations of the World Health Organization

Birth centers are maternal care models that use appropriate technology when providing care to birthing women. This descriptive study aimed to characterize intrapartum care in a freestanding birth center, in light of the practices recommended by the World Health Organization (WHO), with 1,079 assisted births from 2006 to 2009 in the Sapopemba Birth Center, São Paulo, Brazil. Results included the use of intermittent auscultation (mean=7 controls); maternal positions during delivery: semi-sitting (82.3%), side-lying (16.0%), other positions (1.7%), oral intake (95.6%); companionship (93.3%); exposure to up to three vaginal examinations (85.4%), shower bathing (84.0%), walking (68.0%), massage (60.1%), exercising with a Swiss ball (51.7%); amniotomy (53.4%), oxytocin use during the first (31.0%) and second stages of labor (25.8%), bath immersion (29.3%) and episiotomy (14.1%). In this birth center, care providers used practices recommended by the WHO, although some practices might have been applied less frequently.

Improving patient safety: how and why incidences occur in nursing care

The present investigation was a cross-sectional, quantitative research study analyzing incidents associated with nursing care using a root-cause methodological analysis. The study was conducted in a public hospital intensive care unit (ICU) in Santiago de Chile and investigated 18 incidents related to nursing care that occurred from January to March of 2012. The sample was composed of six cases involving medications and the self-removal of therapeutic devices. The contributing factors were related to the tasks and technology, the professional work team, the patients, and the environment. The analysis confirmed that the cases presented with similar contributing factors, thereby indicating that the vulnerable aspects of the system are primarily responsible for the incidence occurrence. We conclude that root-cause analysis facilitates the identification of these vulnerable points. Proactive management in system-error prevention is made possible by recommendations.

Comfort of the patient's family in an Intensive Care Unit related to welcoming

This study aimed to identify the level of comfort of families of patients in a critical health condition related to the welcoming practices performed by the hospital staff. Interviews were conducted with 250 relatives in hospitals of the state Bahia, using a Likert scale. Data were analyzed as percentages and quartiles. For nine of the 12 statements of the scale, most relatives scored their comfort level between very and totally comfortable, median of 4,revealing kindness, tranquility and friendly communication with family members. More than half of the sample scored its level as not at all to more or less comfortable, median of 3, for statements about demonstration of interest towards the relative by the staff and flexible visiting of the patient. The necessity of greater interest of the team in the condition and needs of the family was observed. Promoting comfort from the dimension of welcoming demands interdisciplinary actions grounded in humanistic philosophy, in which the nurse has an important role to play.

Evaluation of patients with stroke monitored by home care programs

The purpose of this study was to evaluate the patient with a stroke in home treatment, investigating physical capacity, mental status and anthropometric analysis. This was a cross-sectional study conducted in Fortaleza/CE, from January to April of 2010. Sixty-one individuals monitored by a home care program of three tertiary hospitals were investigated, through interviews and the application of scales. The majority of individuals encountered were female (59%), elderly, bedridden, with a low educational level, a history of other stroke, a high degree of dependence for basic (73.8%) and instrumental (80.3 %) activities of daily living, and a low cognitive level (95.1%). Individuals also presented with tracheostomy, gastric feeding and urinary catheter, difficulty hearing, speaking, chewing, swallowing, and those making daily use of various medications. It was concluded that home care by nurses is an alternative for care of those individuals with a stroke.

Ability for self-care and its association with sociodemographic factors of people with spinal cord injury

This study aimed to verify the association between self-care ability and sociodemographic factors of people with spinal cord injury (SCI). It was a cross-sectional study, conducted in 2012, in all 58 Basic Health Units of Natal/RN, Brazil. Seventy-three subjects completed a sociodemographic form andSelf-Care Agency Scale. Statistical analyses were performed using SPSS,including Cronbach’s Alpha, Chi-square, Fisher’s and contingency coefficient tests. The Cronbach's alpha was 0.788. The result verified that sex (p = 0.028), religion (p <0.001), education (p = 0.046), current age (p = 0.027), SCI time (p = 0.020) and the SCI type (p = 0.012) were variables associated with self-care ability of the subjects. It was concluded that sociodemographic factors may interfere with the self-care ability of persons with SCI, and nurses should consider this aspect during the execution of the nursing process.

Warning systems in a computerized nursing process for Intensive Care Units

A hybrid study combining technological production and methodological research aiming to establish associations between the data and information that are part of a Computerized Nursing Process according to the ICNP® Version 1.0, indicators of patient safety and quality of care. Based on the guidelines of the Agency for Healthcare Research and Quality and the American Association of Critical Care Nurses for the expansion of warning systems, five warning systems were developed: potential for iatrogenic pneumothorax, potential for care-related infections, potential for suture dehiscence in patients after abdominal or pelvic surgery, potential for loss of vascular access, and potential for endotracheal extubation. The warning systems are a continuous computerized resource of essential situations that promote patient safety and enable the construction of a way to stimulate clinical reasoning and support clinical decision making of nurses in intensive care.

Social Representations Of Violence Against Rural Women: Unveiling Senses In Multiple Views

We analyze the social representations of violence against women from the perspective of city managers, professionals and health workers in rural settings of the southern half of Rio Grande do Sul. The study has a qualitative approach and adds a theoretical/methodological perspective of social representations. The data were generated by means of the associative method, question-stimulus of words and expressions emergence. The analysis of word association was performed with EVOC software, considering frequency and order of association with inducing terms. Participants recognize violence against women as gender destination that induces consent, resignation, guilt and fear, and results in naturalization and trivialization of this social phenomenon. We highlight the need to produce ruptures in established and traditional forms of health care, in the conservative and stereotypical views of violence, favoring access to friendly service and avoiding the reproduction of gender inequalities.


Pressure Ulcers In Palliative home Care Patients: Prevalence And Characteristics

Persons in palliative care develop pressure ulcers (PU) as death approaches, but the extent of the problem is still unknown. The objectives were to identify the prevalence of pressure ulcers in people with cancer in palliative home care, compare the socio-demographic and clinical profile of patients with and without pressure ulcers, and analyze the characteristics of the ulcers. This descriptive, cross-sectional study included 64 people with advanced cancer in palliative home care. Twelve of them (18.8%) had PU, of whom 75.0% were men. The participants had one to three PU, amounting to 19 lesions, 89.4% of those developed at home and 47.4% at stage 3. The presence of PU was higher among those who had a history of previous wound. PU consisted of a significant event occurring in the studied population, indicating that preventive measures should be included in the home palliative care health team.
