Validity, sensitivity and specificity of a measure of medication adherence instrument among patients taking oral anticoagulants.

Although self-report instruments are currently considered a valuable tool for measuring adherence, due to their low cost and ease of implementation, there are still important factors that impact measurement accuracy, such as social desirability and memory bias. Thus, the Global Assessment of Medication Adherence Instrument (GEMA) was developed to provide an accurate measure of this construct. The aim of this study was to evaluate the properties of the measurement of the Global Evaluation of Medication Adherence Instrument (GEMA) among patients with chronic diseases. A methodological study was conducted in the public hospital of the state of São Paulo, Brazil. The adherence to anticoagulants as well as the international normalized ratio (INR) was assessed on 127 patients. Besides GEMA, two other instruments were used to assess adherence: the Morisky Medication Adherence Scale-8 (MMAS-8) and the Measurement of Adhesion to Treatments (MAT). The GEMA presented a satisfactory level of specificity (0.76) to identify adherents among those with a stable INR, low sensitivity (0.43) for the identification of non-adherents among those with an unstable INR, and a Positive Predictive Value of 0.70. Positive and weak to moderate correlations were observed between the proportion of doses assessed with GEMA and the scores on the MMAS-8 (r = .26 and r = .22, respectively) and the MAT (r = .22 and r = .30, respectively). The GEMA presented good practicality, acceptability, and evidence of specificity regarding the stability of the INR. The validity of the construct was partially supported by the relationship with self-reported measures of adherence.

Driveline dressings used in heartmate patients and local complications: A retrospective cohort.

BACKGROUND: Patients with long-term ventricular assist devices (VAD) are predisposed to infection, bleeding, and pressure injuries at the insertion of the driveline. There is no consensus on a driveline dressing protocol. Chlorhexidine is often used to clean the driveline exit site and has been associated with lower rates of infection. For driveline coverage, bacteriostatic agents and transparent film have shown good results, but are costly. The same issue was associated with anchorage devices. OBJECTIVES: The purpose of this study was to evaluate the types of dressings used in the driveline of patients using HeartMate (HM) and to describe the incidence density of local complications (infection, bleeding, and pressure injury) within 30 days postoperatively. METHODS: A retrospective cohort study was conducted and included 22 patients admitted to the Intensive Care Unit after implantation of HM II and III in a Brazilian private hospital. RESULTS: Several types of dressings were used in the drivelines. There were 22 different types of dressings. Dressing type 6 (Chlorhexidine, Excilon, Gauze and IV3000) were the most used (45.4%). Subjects using the Flexi-Trak anchoring device had a higher rate of local bleeding (50.0%) and those who used the Hollister device had more infection (61.1%) and pressure injury associated with a medical device (11.1%), compared to others. Infection was the primary complication (45.4%), followed by local bleeding (27.7%). CONCLUSION: Despite the high variability of products used in the driveline of patients using HeartMate, the dressing made with chlorhexidine, silver-impregnated absorbent foam and transparent film, and the use of anchoring devices was the most frequently used. Infection was the most common complication.

Communicating bad news in the practice of nursing: an integrative review.

OBJECTIVE: To analyze current scientific knowledge about communication of bad news by nurses. METHODS: This is an integrative literature review carried out by searching articles published in national and international journals indexed at SciELO, MEDLINE® (PubMed®), Scopus, Bireme and CINAHL, from 2010 to 2020, by crossing the controlled descriptors "communication", "revelation of the truth", and "nursing", and the uncontrolled descriptor "bad news". RESULTS: Ten articles with qualitative and cross-sectional design, as well as case reports were included. The analysis indicated the evidence available in the literature showed the nurses' lack of ability to communicate bad news, although they are professionals who have close contact with patients and families and who establish a strong bond with them, and often face challenging situations for communicating bad news. CONCLUSION: There is an evident need to invest in training of nurses on skills to communicate bad news and establish a nurse-patient bond when dialoguing with the family. There are few studies in the literature addressing this issue; therefore, it is recommended to perform research that can contribute to improvements in the clinical practice and developing protocols to promote such care.

Impact of a Theory-Based Intervention to Promote Medication Adherence in Patients With a History of Myocardial Infarction.

BACKGROUND: Patient discontinuation of cardioprotective medications after a cardiac ischemic event commonly occurs early after hospital discharge. Theory-based interventions could be effective in promoting better patient self-regulation of health-related behaviors and positive intentions to adhere to the recommended medical regimen. OBJECTIVE: The aim of this study was to evaluate the potential efficacy and feasibility of a theory-based intervention to promote adherence to cardioprotective medications. METHODS: In this mixed-methods quasi-experimental study with 3 time points, we recruited 45 participants with a positive intention to adhere and a history of myocardial infarction. They were recruited in primary care units in Brazil. Data collection occurred in 2 waves (Tb and T60). The intervention consisted of developing action and coping plans, delivered in a 30-minute face-to-face session, with face-to-face reinforcement at a 30-day interval. Quantitative data were submitted to descriptive, Wilcoxon, and McNemar analyses; qualitative data were submitted to content analysis. RESULTS: An increase in the proportion of patients adhering to medications at the end of follow-up was found (T60 - Tb, +60.0%; P < .001). In addition, a significant reduction was found for blood pressure (T60 - Tb, -8.6 mm Hg; P < .001), heart rate (T60 - Tb, -6.6 bpm; P < .001), and low-density lipoprotein (T60 - Tb, -6.2 mg/dL; P < .05). Qualitative results revealed that the intervention was feasible, with an attrition rate of zero. The intervention was found to be easy to apply to patients' daily lives, and there was adequate time for implementation. CONCLUSIONS: Our data confirm the potential efficacy of a theory-based intervention on the promotion of adherence to cardioprotective medications and on the related clinical end points, as well as its feasibility in the clinical context (Universal Trial Number: U1111-1189-9967).

Implementing healthcare professionals' training during COVID-19: a pre and post-test design for simulation training.

BACKGROUND: Coronavirus disease-19 (COVID-19) has imposed a new reality that presents several challenges for healthcare professionals. The main challenge has been the lack of proper training in relation to an unknown disease. OBJECTIVE: To investigate healthcare professionals' acquisition of knowledge of a new airway management protocol for COVID-19 through their participation in simulation training. DESIGN AND SETTING: Pre and post-test study with purpose sampling, carried out in a tertiary-level hospital in the city of Campinas, state of São Paulo, Brazil. METHODS: This was a cross-sectional pre and post-test intervention among healthcare professionals working in the intensive care unit and emergency department of a large hospital. The training was carried out using an in situ simulation scenario and the participants answered pre and post-tests consisting of a 20-item questionnaire about the new protocol. RESULTS: The paired-sample t test demonstrated that there was a significant increase in test score (t = -19.06; P < 0.001), from before the training (M = 8.62; standard deviation, SD = 3.53) to after the simulation training (M = 17.02; SD = 1.76). CONCLUSIONS: The simulated training had a positive impact on the healthcare professionals' acquisition of the COVID-19 protocol. We also demonstrated that in situ simulation training was an efficient tool for implementing new protocols, thus bringing benefits to healthcare systems, professionals and patients.

Profile of potential organ donors and factors related to donation and non- donation of organs in an Organ Procurement Service. / Perfil dos potenciais doadores de órgãos e fatores relacionados à doação e a não doação de órgãos de uma Organização de Procura de Órgãos.

OBJECTIVE: to characterize the profile of potential and effective organ donors, and to identify the factors related to non-donation. METHODS: the data was collected from the Organization of Organ Donation forms during the period of January 2013 to April 2018. The statistical analysis was done by the Biostatistic Service of the School of Medical Sciences of UNICAMP. RESULTS: the study analyzed 1,772 potential donors; the male gender was predominant (57.39%). Vascular injuries (n=996) were the main cause of brain death. The family refusal (42.8%) was the leading cause of non-donation of organs. There was statistical difference between donors and non-donors in regard to the mean age and mean systolic blood pressure. There was also a relationship between the donation of organs and the absence of diabetes and smoking. CONCLUSION: the majority of effective organ donors were young males. The main causes of brain death (BD) and family refusal of organ donation were cerebrovascular disorder and no desire to donate organs after death, respectively. Alcoholics and males were more frequently found in traumatic causes of BD. Therefore, initiatives for population awareness and discussion among the families regarding organ donation can lead to increase the number of effective organ donors.

OBJETIVO: caracterizar o perfil dos potenciais e dos efetivos doadores de órgãos, e identificar os fatores relacionados a não efetivação da doação. MÉTODOS: estudo retrospectivo transversal com coleta de dados das fichas da Organização de Procura de Órgãos do Hospital das Clínicas da Unicamp, referente ao período de janeiro de 2013 a abril de 2018. RESULTADOS: o estudo contou com 1.772 potenciais doadores; predominou-se o sexo masculino (57,39%) e o evento vascular (n=996) foi a principal causa de morte encefálica. A recusa familiar (42,8%) foi o motivo mais comum para não doação de órgãos. Houve diferença estatística entre doadores e não doadores quanto à média de idade e pressão arterial sistólica, assim como houve relação entre a doação de órgãos e a ausência de diabetes e tabagismo. CONCLUSÃO: a maioria dos doadores efetivos foi do sexo masculino e jovem. As principais causas de morte encefálica e de recusa familiar foram, respectivamente, vasculares e não manifestação da vontade de ser doador após a morte. O etilismo foi mais presente nas causas traumáticas, assim como, o sexo masculino. Assim, iniciativas de conscientização populacional e abertura de discussão dentro da família sobre o ato da doação contribuem para o aumento do índice de doadores efetivos.

Reliability and construct validity of the Instrument to Measure the Impact of Valve Heart Disease on the Patient's Daily Life.

Objective: evaluate the practicality, acceptability and the floor and ceiling effects, estimate the reliability and verify the convergent construct's validity with the instrument called the Heart Valve Disease Impact on daily life (IDCV) of the valve disease in patients with mitral and or aortic heart valve disease. Method: data was obtained from 86 heart valve disease patients through 3 phases: a face to face interview for a socio-demographic and clinic characterization and then other two done through phone calls of the interviewed patients for application of the instrument (test and repeat test). Results: as for the practicality and acceptability, the instrument was applied with an average time of 9,9 minutes and with 110% of responses, respectively. Ceiling and floor effects observed for all domains, especially floor effect. Reliability was tested using the test - repeating pattern to give evidence of temporal stability of the measurement. Significant negative correlations with moderate to strong magnitude were found between the score of the generic question about the impact of the disease and the scores of IDCV, which points to the validity of the instrument convergent construct. Conclusion: the instrument to measure the impact of valve heart disease on the patient's daily life showed evidence of reliability and validity when applied to patients with heart valve disease.

Factor analysis of an instrument to measure the impact of disease on daily life. / Análise de fatores do instrumento de medida do impacto da doença no cotidiano.

OBJECTIVE: to verify the structure of factors of an instrument to measure the Heart Valve Disease Impact on Daily Life (IDCV) when applied to coronary artery disease patients. METHOD: the study included 153 coronary artery disease patients undergoing outpatient follow-up care. The IDCV structure of factors was initially assessed by means of confirmatory factor analysis and, subsequently, by exploratory factor analysis. The Varimax rotation method was used to estimate the main components of analysis, eigenvalues greater than one for extraction of factors, and factor loading greater than 0.40 for selection of items. Internal consistency was estimated using Cronbach's alpha coefficient. RESULTS: confirmatory factor analysis did not confirm the original structure of factors of the IDCV. Exploratory factor analysis showed three dimensions, which together explained 78% of the measurement variance. CONCLUSION: future studies with expansion of case selection are necessary to confirm the IDCV new structure of factors.

Adaptation and evaluation of the measurement properties of the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale.

OBJECTIVES: to undertake the cultural adaptation of, and to evaluate the measurement properties of, the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale in coronary heart disease (CHD) patients, with outpatient monitoring at a teaching hospital. METHOD: the process of cultural adaptation was undertaken in accordance with the international literature. The data were obtained from 147 CHD patients, through the application of the sociodemographic/clinical characterization instrument, and of the Brazilian versions of the Morisky Self-Reported Measure of Medication Adherence Scale, the General Perceived Self-Efficacy Scale, and the Self-efficacy for Appropriate Medication Adherence Scale. RESULTS: the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale presented evidence of semantic-idiomatic, conceptual and cultural equivalencies, with high acceptability and practicality. The floor effect was evidenced for the total score and for the domains of the scale studied. The findings evidenced the measure's reliability. The domains of the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale presented significant inverse correlations of moderate to strong magnitude between the scores of the Morisky scale, indicating convergent validity, although correlations with the measure of general self-efficacy were not evidenced. The validity of known groups was supported, as the scale discriminated between "adherents" and "non-adherents" to the medications, as well as to "sufficient dose" and "insufficient dose". CONCLUSION: the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale presented evidence of reliability and validity in coronary heart disease outpatients.

Construct Validity of the Brazilian Version of the Self-Efficacy for Appropriate Medication Adherence Scale.

BACKGROUND AND PURPOSE: This study aimed to evaluate the reliability and the construct validity of the Brazilian version of the Self-Efficacy for Appropriate Medication Adherence Scale (SEAMS). METHODS: One hundred forty-seven patients with coronary artery disease participated in the study. Reliability was estimated by composite reliability (CR). Convergent validity was estimated by the factor loading and average variance extracted (AVE). The discriminant validity was assessed by cross-factor loadings, comparing the square roots of AVEs by correlation coefficients between latent constructs and disattenuated correlation. RESULTS: The values of CR of .88 and .99 for Factors 1 and 2, respectively, indicate internal consistency reliability. Values of AVE = 0.52 for Factor 1 and 0.69 for Factor 2 to the convergent validity of the model. Cross-factor loadings were found ≥.50 for all items of the scale in areas that were allocated in the original instrument, square roots of AVEs higher than the correlations between the constructs and desatenuada correlation (r = .83), suggesting discriminant validity fashion model. CONCLUSION: Confirmatory factor analysis partially yielded the construct validity of the Brazilian version of the SEAMS.

Influence of sociodemographic and clinical characteristics at the impact of valvular heart disease.

OBJECTIVE: to analyze the sociodemographic and clinical characteristics of patients with valvular heart disease and to verify the influence of these variables on the impact of valve disease in daily life. METHOD: the study involved 86 outpatients. Data collection was performed in two stages - face-to-face interview for sociodemographic and clinical characterization and through telephone contact for the application of the Instrument to Measure the Impact of Valvular Heart Disease on Patient's Everyday Life (IDCV). Data were analyzed through descriptive statistics and multiple regression analysis. RESULTS: it was noticed that the total score of IDCV and its domains were influenced by age, schooling, presence or absence of symptoms, use or not of diuretic. CONCLUSION: The impact of the disease was influenced by sociodemographic and clinical variables. The results provide subsidies for the design of nursing interventions aimed at reducing the impact of the disease on the patient's daily life with valve disease.
