Motivational drivers for health professionals in a large quality improvement collaborative project in Brazil: a qualitative study.

BACKGROUND: The success of collaborative quality improvement (QI) projects in healthcare depends on the context and engagement of health teams; however, the factors that modulate teams' motivation to participate in these projects are still unclear. The objective of the current study was to explore the barriers to and facilitators of motivation; the perspective was health professionals in a large project aiming to implement evidence-based infection prevention practices in intensive care units of Brazilian hospitals. METHODS: This qualitative study was based on content analysis of semistructured in-depth interviews held with health professionals who participated in a collaborative QI project named "Improving patient safety on a large scale in Brazil". In accordance with the principle of saturation, we selected a final sample of 12 hospitals located throughout the five regions of Brazil that have implemented QI; then, we conducted videoconference interviews with 28 health professionals from those hospitals. We encoded the interview data with NVivo software, and the interrelations among the data were assessed with the COM-B model. RESULTS: The key barriers identified were belief that improvement increases workload, lack of knowledge about quality improvement, resistance to change, minimal involvement of physicians, lack of supplies, lack support from senior managers and work overload. The primary driver of motivation was tangible outcomes, as evidenced by a decrease in infections. Additionally, factors such as the active participation of senior managers, teamwork, learning in practice and understanding the reason for changes played significant roles in fostering motivation. CONCLUSION: The motivation of health professionals to participate in collaborative QI projects is driven by a variety of barriers and facilitators. The interactions between the senior manager, quality improvement teams, and healthcare professionals generate attitudes that modulate motivation. Thus, these aspects should be considered during the implementation of such projects. Future research could explore the cost-effectiveness of motivational approaches.

Improvement of quality of care for gestational syphilis in the municipality of Rio de Janeiro.

OBJECTIVE: To analyze the effect of a multifaceted intervention in the care of pregnant women with syphilis in primary health care. METHODS: This is a quality improvement project performed in 26 basic care units in the municipality of Rio de Janeiro, between January and December 2017. It has a quasi-experimental mixed design, with previous, later and time series analyses. We evaluated the care provided to all pregnant women with syphilis whose prenatal care that ended during the studied period, using ten quality criteria and one indicator. The intervention was multifaceted, covering permanent education, improvement of records and information systems, audit and feedback, patient education, organizational changes and work processes. We estimated absolute and relative improvements of the criteria and their statistical significance (α = 5%). The facilitators and hinders of the intervention were analyzed according to the Model for Understanding Success in Quality. RESULTS: After the intervention, there was a total absolute improvement of 6.7% (64.4% versus 71.0%) and relative of 28.8% (p > 0.05). Eight of the ten quality criteria had an improvement, which was significant in four of them (p < 0.05). The monthly indicator of adequate treatment also improved (p < 0.05), but maintained low performance throughout the project. The increase in the compliance of the treatment scheme with the protocol (91.4% versus 99.1%) positively stood out, but the main opportunities for improvement were testing (42.8% versus 48.5%) and treatment of sexual partnerships (42.8% versus 44.2%). Regulatory pressures to improve the monthly indicator and the political-economic crisis experienced by the municipality modulated the effect of the intervention. CONCLUSION: The project was useful to identify priorities and guide interventions to improve the quality of care for syphilis, although there is still ample room for improvement. The identified problems, as well as the contextual modulators of the effect, should be considered in future interventions.

Survival analysis of patients with sepsis in Brazil.

INTRODUCTION: This study aimed to analyze the survival of septic patients and to assess prognostic factors. METHODS: Patients with sepsis, severe sepsis, and septic shock were followed up and clinical and laboratory data were collected. The sepsis-related organ failure assessment (SOFA) score was calculated. RESULTS: The overall 30-day survival rates of patients with sepsis, severe sepsis, and septic shock were 86.3%, 72.5%, and 20%, respectively. Mortality was related to old age, septic shock, coagulopathy, lactate level, and high SOFA score among other factors. CONCLUSIONS: Identification of prognostic variables may reduce sepsis-related mortality.

Assessment of the risk of QT-interval prolongation associated with potential drug-drug interactions in patients admitted to Intensive Care Units.

OBJECTIVES: To evaluate the relationship between drug interactions and QT-interval prolongation in patients admitted to a general intensive care unit (ICU). METHODS: This study was approved by the Institutional Review Board and written informed consent was obtained from all patients. From May 2015 to July 2016, all patients over 18 years-old admitted to the ICU for more than 24 h and in whom the QT-interval on the ECG could be read were prospectively included in this observational, cross-sectional study. All medications administered in the 24 h prior to admission were recorded and the QT-interval was measured upon ICU admission and corrected with Bazzet's formula (QTc). Drug-drug interactions involving drugs potentially associated with QTc prolongation (DDIQT) were searched and QTc increase associated with pharmacokinetic (PK-DDIQT) and pharmacodynamic (PD-DDIQT) interactions was assessed with multiple regression adjusted by patient varibles. RESULTS: The study population consisted of 283 patients, 54.4% males, mean age 57.6 ±â€¯16.7 years-old. Forty five (15.9%) patients presented 65 DDIQT with predominance of pharmacodynamic (66.1%). The risk of DDIQT prescription increased with lower systolic blood pressure, in hypokalemia, in non-diabetics and with the number of medications. PK-DDIQT alone did not affect the QTc interval (7.75 ms, 95%CI: -22.4 to 37.9 ms, p = 0.61), but PD-DDIQT increased QTc by 28.4 ms (95%CI: 9.67 to 47.4 ms, p = 0.003). Most PD-DDIQT involved metoclopramide with ondansetron or amiodarone, and ondansetron with ciprofloxacin. CONCLUSIONS: In patients exposed to drugs associated with prolonged QTc in the 24 h prior to ICU admission, pharmacodynamic DDIQT are associated with increased risk of QTc prolongation.

QTc interval prolongation in critically ill patients: Prevalence, risk factors and associated medications.

PURPOSE: To investigate the prevalence and risk factors of acquired long QT syndrome (LQTS) on admission to a general Intensive Care Unit (ICU), and to assess the risk of LQTS associated with prescribed medications. METHODS: Prospective observational, cross-sectional study approved by the Institutional Review Board. Between May 2014 and July 2016, 412 patients >18 years-old consecutively admitted to the ICU of a university hospital were included. LQTS was defined as a QT interval on the admission electrocardiogram corrected using Bazett's formula (QTc) >460 ms for men and >470 ms for women. All medications administered within 24 hours before admission were recorded. Logistic regression was used. RESULTS: LQTS prevalence was 27.9%. In LQTS patients, 70.4% had ≥ 1 LQTS-inducing drug prescribed in the 24 hours prior to ICU admission versus 70.4% in non-LQTS patients (p = 0.99). Bradycardia and Charlson morbidity index score are independent risk factors for LQTS. Haloperidol (OR 4.416), amiodarone (OR 2.509) and furosemide (OR 1.895) were associated with LQTS, as well as another drug not yet described, namely clopidogrel (OR 2.241). CONCLUSIONS: The LQTS is highly prevalent in critically ill patients, ICU patients are often admitted with LQTS-inducing medications, and patients with slow heart rate or with high Charlson comorbidity index should be evaluated for LQTS.

Effects of a Physical Activity Program on Cardiorespiratory Fitness and Pulmonary Function in Obese Women after Bariatric Surgery: a Pilot Study.

BACKGROUND: In severely obese individuals, reducing body weight induced by bariatric surgery is able to promote a reduction in comorbidities and improve respiratory symptoms. However, cardiorespiratory fitness (CRF) reflected by peak oxygen uptake (VO2peak) may not improve in individuals who remain sedentary post-surgery. The objective of this study was to evaluate the effects of a physical training program on CRF and pulmonary function in obese women after bariatric surgery, and to compare them to a control group. METHODS: Twelve obese female candidates for bariatric surgery were evaluated in the preoperative, 3 months postoperative (3MPO), and 6 months postoperative (6MPO) periods through anthropometry, spirometry, and cardiopulmonary exercise testing (CPX). In the 3MPO period, patients were divided into control group (CG, n = 6) and intervention group (IG, n = 6). CG received only general guidelines while IG underwent a structured and supervised physical training program involving aerobic and resistance exercises, lasting 12 weeks. RESULTS: All patients had a significant reduction in anthropometric measurements and an increase in lung function after surgery, with no difference between groups. However, only IG presented a significant increase (p < 0.05) in VO2peak and total CPX duration of 5.9 mL/kg/min (23.8%) and 4.9 min (42.9%), respectively. CONCLUSIONS: Applying a physical training program to a group of obese women after 3 months of bariatric surgery could promote a significant increase in CRF only in the trained group, yet also showing that bariatric surgery alone caused an improvement in the lung function of both groups.

Unraveling microbial biofilms of importance for food microbiology.

The presence of biofilms is a relevant risk factors in the food industry due to the potential contamination of food products with pathogenic and spoilage microorganisms. The majority of bacteria are able to adhere and to form biofilms, where they can persist and survive for days to weeks or even longer, depending on the microorganism and the environmental conditions. The biological cycle of biofilms includes several developmental phases such as: initial attachment, maturation, maintenance, and dispersal. Bacteria in biofilms are generally well protected against environmental stress, consequently, extremely difficult to eradicate and detect in food industry. In the present manuscript, some techniques and compounds used to control and to prevent the biofilm formation are presented and discussed. Moreover, a number of novel techniques have been recently employed to detect and evaluate bacteria attached to surfaces, including real-time polymerase chain reaction (PCR), DNA microarray and confocal laser scanning microscopy. Better knowledge on the architecture, physiology and molecular signaling in biofilms can contribute for preventing and controlling food-related spoilage and pathogenic bacteria. The present study highlights basic and applied concepts important for understanding the role of biofilms in bacterial survival, persistence and dissemination in food processing environments.

Current knowledge and perspectives on biofilm formation: the case of Listeria monocytogenes.

Listeriosis is a rare, serious, and mainly food-borne infection caused by the bacterium Listeria monocytogenes. This food-borne infection primarily affects pregnant women and immunologically compromised individuals. L. monocytogenes is recognized as a problem for the food industry, mainly due to its environmental persistence, attributed in part to its ability to form biofilms. Biofilms are microbial communities adhered to biotic or abiotic surfaces coated by self-produced extracellular polymers. These structures confer protection to bacterial cells and decrease the efficiency of cleaning and disinfection procedures. This article presents a brief review of current perspectives on the formation of biofilms, with emphasis on L. monocytogenes, highlighting the importance of cell-to-cell communication and structural composition of the microbial communities. The techniques currently used to study biofilms and the need to develop new strategies for the prevention and control of biofilm-forming pathogens are also discussed.

Intensidades de treinamento resistido e pressão arterial de idosas hipertensas - um estudo piloto / Resistance training intensities and blood pressure of hypertensive older women - a pilot study

INTRODUÇÃO: Observa-se que a literatura apresenta uma lacuna acerca da intensidade ideal de treinamento resistido para idosos hipertensos, os poucos estudos existentes utilizam treinamentos com diferentes intensidades. OBJETIVO: Verificar o efeito de duas intensidades de treinamento resistido sobre a pressão arterial de idosas hipertensas controladas. Métodos: Dezesseis idosas hipertensas, controladas por medicação anti-hipertensiva, foram divididas em dois grupos através de sorteio. Nove pacientes foram submetidas a treinamento resistido moderado (G1) e sete, a treinamento resistido leve (G2). As pacientes realizaram oito semanas de treinamento resistido, com frequência de três vezes por semana em dias alternados, no período vespertino. Os exercícios realizados foram respectivamente: leg press, supino reto, extensão de joelhos, puxada frontal, flexão de joelhos, abdução de ombro, abdução unilateral de quadril com cross over e rosca direta com barra. RESULTADOS: As pacientes do G1 apresentaram redução tanto nos valores de repouso da pressão arterial diastólica (PAD) p < 0,03, como da pressão arterial média (PAM) p < 0,03. O G2, por sua vez, apresentou redução nos valores de repouso da PAM (p < 0,03) e uma tendência à redução na PAD (p < 0,06). A magnitude de queda em ambos os grupos foi superior aos valores apresentados na literatura. CONCLUSÂO: Tanto o treinamento resistido moderado quanto o leve, mesmo quando iniciados na terceira idade, promoveram benefícios cardiovasculares. Ambos podem ser indicados como tratamento coadjuvante para idosas hipertensas controladas por medicação.

BACKGROUND: The optimum intensity of resistance training for hypertensive elderly has not been studied yet and the few studies in the literature used training with distinct intensities. Objective: To verify the effect of two resistance training intensities on blood pressure (BP) of elderly women with controlled hypertension. METHODS: Sixteen older women with hypertension controlled by anti-hypertensive drug were randomly divided into two groups. Nine patients were submitted to moderate resistance training (G1) and seven patients were submitted to mild resistance training (G2). The patients underwent eight weeks of resistance training, with frequency of three times per week on alternate days in the afternoon. The exercises performed were: leg press, bench press, knee extension, lat pull-down, knee flexion, shoulder abduction, standing cable hip abduction and biceps curl. RESULTS: G1 patients presented reduction in both resting values in diastolic blood pressure (DBP) p<0.03 and mean arterial pressure (MAP) p<0.03. G2 presented decrease in resting values of MAP (p<0.03) and a tendency to decrease in DBP (p<0.06). Magnitude of values decrease in both groups was higher than the ones reported in the literature. CONCLUSION: Both light and moderate training promoted cardiovascular benefits, even when initiated at old age. Moreover, both can be indicated as supporting treatment for older women with hypertension controlled by medication.

Analysis of heart rate variability in polycystic ovary syndrome.

OBJECTIVE: To compare the modulation of heart rate in a group of volunteers with polycystic ovary syndrome (PCOS) to that of a group of healthy ovulatory women on the basis of R-R interval variability and analyze the relationships between heart rate variability (HRV) and other cardiovascular risk factors. METHODS: In a cross-sectional study, HRV and anthropometric, biochemical and hormonal parameters were measured in 23 women with PCOS and 23 age-matched controls. Mean outcomes measures: HRV indexes in the time (SDNN and rMSSD) and frequency domain (low frequency-LF and high frequency-HF). Differences between groups and correlation analysis were performed. RESULTS: Intergroup analysis showed significant differences (p < 0.05) between groups, with lower SDNN, rMSSD, LF and HF indexes in PCOS women when compared to the control group. There was significant negative correlation between BMI and SDNN, LF and HF, indicating a decrease in the autonomic modulation of heart rate with increasing weight. A negative correlation was also found between the high-sensitivity C-reactive protein level and the rMSSD index. CONCLUSION: Our results show that PCOS is associated with alterations in the autonomic modulation of heart rate, possibly due to the influence of weight gain.
