Factors related to health literacy among Brazilian adolescents: cross-sectional study.

OBJECTIVE: To analyze the relationship between sociodemographic and clinical factors with health literacy in Brazilian adolescents. METHOD: This is a cross-sectional study with 526 adolescents aged 14 to 19. Data were collected virtually between July and September 2021 using a sociodemographic characterization questionnaire, clinical profile and the Health Literacy Assessment Tool - Portuguese version. The variables were evaluated by multiple linear regression with normal response, with significance p < 0.05. RESULTS: The average age was 16.9 years (±1.6), the average health literacy score was 25.3 (±5.4). Female gender (p = 0.014), university educational level (p = 0.002) and use of medication (p = 0.020) were related to higher levels of health literacy. Adolescents with chronic illnesses had a higher total literacy score, on average 1.51 points, compared to those without chronic illnesses. CONCLUSION: Male adolescents and those with less education performed worse in health literacy and, therefore, deserve special attention in health promotion actions.

Factors associated with the evolution of COVID-19 in pregnant women: a Brazilian population-based study.

OBJECTIVE: To assess the evolution of COVID-19 among Brazilian pregnant women, identifying sociodemographic and clinical predictors related to admission to ICU - Intensive Care Unit and death. METHOD: Cross-sectional, population-based study, carried out with a secondary database, based on data from the Influenza Epidemiological Surveillance Information System. Descriptive analysis was performed, followed by multiple linear regression with Poisson response, adopting critical p < 0.05. RESULTS: Intensive care admission rates of 28.2% and death rates of 9.5% were identified. Region of residence, gestational trimester, number of comorbidities and respiratory signs and symptoms were associated with the risk of admission to intensive care. Age over 34 years, comorbidities, oxygen saturation equal to or less than 95%, admission to intensive care and ventilatory support, invasive or not, increased the risk of death. CONCLUSION: Sociodemographic and clinical predictors showed an association with hospitalization in intensive care and death of pregnant women with COVID-19.

Effect of a Physical Exercise Program on the Inflammatory Response, Cardiac Functions, Functional Capacity, and Quality of Life in Patients with Sickle Cell Disease.

INTRODUCTION: The beneficial effects of physical exercise on functional capacity and inflammatory response are well-known in cardiovascular diseases; however, studies on sickle cell disease (SCD) are limited. It was hypothesized that physical exercise may exert a favorable effect on the inflammatory response of SCD patients, contributing to an improved quality of life. This study aimed to evaluate the effect of a regular physical exercise program on the anti-inflammatory responses in SCD patients. METHODS: A non-randomized clinical trial was conducted in adult SCD patients. The patients were divided into two groups: 1-Exercise Group, which received a physical exercise program three times a week for 8 weeks, and; 2-Control Group, with routine physical activities. All patients underwent the following procedures initially and after eight weeks of protocol: clinical evaluation, physical evaluation, laboratory evaluation, quality of life evaluation, and echocardiographic evaluation. STATISTICAL ANALYSIS: Comparisons between groups were made using Student's t-test, Mann-Whitney test, chi-square test, or Fisher's exact test. Spearman's correlation coefficient was calculated. The significance level was set at p < 0.05. RESULTS: There was no significant difference in inflammatory response between the Control and Exercise Groups. The Exercise Group showed an improvement in peak VO2 values (p < 0.001), an increase in the distance walked (p < 0.001), an improvement in the limitation domain due to the physical aspects of the 36-Item Short Form Health Survey (SF-36) quality of life questionnaire (p = 0.022), and an increase in physical activity related to leisure (p < 0.001) and walking (p = 0.024) in the International Physical Activity Questionnaire (IPAQ). There was a negative correlation between IL-6 values and distance walked on the treadmill (correlation coefficient -0.444, p = 0.020) and the estimated peak VO2 values (correlation coefficient -0.480; p = 0.013) in SCD patients in both groups. CONCLUSIONS: The aerobic exercise program did not change the inflammatory response profile of SCD patients, nor did it show unfavorable effects on the parameters evaluated, and patients with lower functional capacity were those with the highest levels of IL-6.

Evolution of Myocardial Hypertrophy Associated With Pregnancy in Hypertensive Women Six Months Postpartum.

Systemic arterial hypertension (SAH) is one of the principal risk factors for developing cardiovascular disease. When a hypertensive woman becomes pregnant, new hemodynamic condition is installed, with addition from chronic pressure overload to chronic volume overload. This new hemodynamic condition can provide greater myocardial hypertrophy(LVH), whose postpartum evolution has been little studied in the literature. To evaluate LVH in hypertensive women in the third trimester of pregnancy and 6 months postpartum and to establish which clinical variables are associated with elevated risk of LVH. Prospective longitudinal study including 41 pregnant women beyond 35 gestational weeks and with previous SAH. They were submitted to clinical and echocardiographic evaluation at the gestational period and 6 months postpartum. Statistical analysis: multivariate logistic regression with the exposures most strongly associated with maintenance of hypertrophy in univariate analysis. Significance level: P<0.05. The mean age was 29±6.2 years. The majority of the women were white(85.4%). Before pregnancy 23(59%) women used antihypertensive drugs and 28(71.8%) used during pregnancy. At the end of gestation, all women presented LVH, 79% maintained hypertrophy 6 months postpartum. In multivariate analysis, exposures significantly associated with hypertrophy maintenance: systolic blood pressure(SBP) at the end of gestation, OR=1.16(1.03-1.30);P=0.013 and SBP increase at 6 months postpartum in relation to end of gestation, OR=22.9(1.8-294);P=0.016. In hypertensive pregnant women, LVH frequency is elevated at the end of pregnancy, and recovery frequency of this hypertrophy, at 6 months postpartum, is very low. The increase of SBP 6 months postpartum was associated with maintenance of hypertrophy.

Association of health literacy, COVID-19 threat, and vaccination intention among Brazilian adolescents.

OBJECTIVE: investigate the influence of health literacy on the assessment of COVID-19 threat to health and the intention not to be vaccinated among Brazilian adolescents. METHOD: cross-sectional study with 526 Brazilian adolescents aged 14 to 19 years. Socioeconomic aspects, health-disease profile, health literacy, health threat by COVID-19 and intention not to be vaccinated were analyzed by bivariate association and multiple linear regression with Poisson response. RESULTS: higher health literacy score (p=0.010), cardiovascular disease (p=0.006), lower income (p=0.000), and living in the North region (p=0.007) were factors that contributed to feeling more threatened by COVID-19. Health literacy did not influence the intention not to be vaccinated (p=0.091), whose prevalence was lower among adolescents in the Southeast region when compared to those in the North region (p=0.010), among those who attended higher education (p=0,049) and those with higher income (p=0.000). CONCLUSION: health literacy influenced the perception of COVID-19 threat, but not the intention not to be vaccinated. Assessment of COVID-19 threat to health and prevalence of the intention not to be vaccinated were influenced by the region of residence, income, and education, which reinforces the importance of social determinants of health in this context. KEYPOINTS: (1) Average health literacy (HL) score of Brazilian adolescents: 25.3 (p-HLAT-8). (2) Adolescents in the Southeast region felt less threatened by COVID-19. (3) Higher HL score indicated adolescents felt more threatened by COVID-19. (4) Intention not to be vaccinated was observed among adolescents with higher income and education. (5) About 87% of Brazilian adolescents want to be vaccinated against COVID-19.

Factors associated with COVID-19 severity among Brazilian pregnant adolescents: a population-based study. / Fatores associados à gravidade da COVID-19 em gestantes adolescentes brasileiras: estudo de base populacional.

OBJECTIVE: to identify the factors associated with need for intensive care unit admission of Brazilian pregnant adolescents with COVID-19. METHOD: population-based non-concurrent cohort study using secondary databases. Brazilian pregnant adolescents who had laboratory confirmation of SARS-CoV-2 by RT-PCR, between March 14, 2020 and April 11, 2021 were included in the study. Statistical analysis using the Poisson multiple regression model, estimating the relative risk and respective 95% confidence intervals, with values of p <0.05 considered significant. RESULTS: in total, 282 pregnant women were included in the study, with median age of 17 years, most with brown skin, in the third trimester of pregnancy, and living in urban or peri-urban areas. The intensive care unit admission rate was 14.5%, associated with living in the Southeast region of Brazil (RR=5.03, 95%CI=1.78-14.24, p=0.002), oxygen saturation below 95% (RR=2.62, 95%CI=1.17-5.87, p=0.019), and having some comorbidity (RR=2.05, 95%CI=1.01-4.16, p=0.047). CONCLUSION: the intensive care unit admission rate was high among Brazilian pregnant adolescents and was associated with living in the Southeast region of Brazil, having some comorbidity and/or presenting low oxygen saturation.(1) The ICU admission rate of pregnant adolescents was high: 14.5%. (2) Low oxygen saturation was a predictor of COVID-19 severity. (3) Living in the Southeast region in Brazil increased the risk of ICU admission by five times. (4) Having some comorbidity increased the risk of ICU admission by two times.

Effect of two combinations of low-dose oral contraceptives on adolescent bone mass: A clinical trial with 2 years follow-up.

INTRODUCTION: Most contraceptive combinations can interfere with the processes of bone formation and resorption. AIM: The aim of this study was to evaluate the effect of 2 combinations of low-dose oral hormonal contraceptives (20 µg ethinyl estradiol [EE]/150 mg desogestrel [COC1] or 30 µg EE/3 mg drospirenone [COC2]) on bone mass acquisition in adolescents over 2 years by means of bone densitometry and measurement of biomarkers of bone remodeling. METHODS: Parallel-group, non-randomized controlled clinical trial of 127 adolescents divided into a control group and 2 groups receiving either COC1 or COC2. The participants were submitted to anthropometric assessment and evaluation of secondary sexual characteristics (Tanner criteria) and bone age. Bone densitometry by dual-energy X-ray absorptiometry and measurement of bone biomarkers (bone alkaline phosphatase, osteocalcin, and C-terminal telopeptide) were performed at baseline and after 24 months. RESULTS: No significant differences in the variables analyzed were observed between COC1 or COC2 users and the control group at baseline. After 24 months, non-users had incorporated more bone mass (content and density) than either group of contraceptive users. This negative impact was more pronounced in the COC2 group than in the COC1 group. A significant reduction in the percentage values of bone alkaline phosphatase and osteocalcin was observed in users of oral contraceptives. CONCLUSION: Bone mass acquisition was compromised in adolescent users of combined hormonal contraceptives. The negative impact was more pronounced in adolescents using contraceptives that contain 30 µg EE/3 mg drospirenone.

Qualidade da Anticoagulação Oral em Pacientes com Fibrilação Atrial em um Hospital Terciário no Brasil / Quality of Oral Anticoagulation in Atrial Fibrillation Patients at a Tertiary Hospital in Brazil

Resumo Fundamento A fibrilação atrial (FA) afeta de 0,5% a 2,0% da população geral e geralmente está associada a doenças estruturais cardíacas, comprometimento hemodinâmico e complicações tromboembólicas. A anticoagulação oral previne eventos tromboembólicos e é monitorada pela razão normalizada internacional (RNI). Objetivos Avaliar a estabilidade do RNI em pacientes com FA não valvar tratados com anticoagulante varfarina, avaliar complicações tromboembólicas ou hemorrágicas e identificar o grupo com risco mais alto de eventos tromboembólicos ou hemorrágicos. Métodos Dados de prontuários médicos de 203 pacientes atendidos em um hospital terciário no Brasil foram analisados e o tempo de intervalo terapêutico (TTR) foi calculado usando-se o método Rosendaal. Em seguida possíveis fatores que influenciam o TTR foram analisados e a relação entre TTR e eventos tromboembólicos ou hemorrágicos foi calculada. O nível de significância foi 5%. Resultados O TTR médio foi 52,2%. Pacientes com instabilidade de RNI na fase de adaptação tinham um TTR médio mais baixo (46,8%) do que aqueles sem instabilidade (53,9%). Entre os pacientes estudados, 6,9% sofreram eventos hemorrágicos e 8,4% tiveram um acidente vascular cerebral. O grupo com risco mais alto de acidente vascular cerebral e sangramento era composto de pacientes com instabilidade de RNI na fase de adaptação. Conclusões A qualidade da anticoagulação nesse hospital terciário no Brasil é semelhante à de centros de países em desenvolvimento. Pacientes com instabilidade de RNI maior na fase de adaptação evoluíram para um TTR médio mais baixo durante o acompanhamento, tinham uma chance de acidente vascular cerebral 4,94 vezes maior e uma chance de sangramento 3,35 vezes maior. Portanto, para esse grupo de pacientes, individualizar a escolha de tratamento anticoagulante seria recomendado, considerando-se a relação custo-benefício.

Abstract Background Atrial fibrillation (AF) affects 0.5% to 2.0% of the general population and is usually associated with cardiac structural diseases, hemodynamic damage, and thromboembolic complications. Oral anticoagulation prevents thromboembolic events and is monitored by the international normalized ratio (INR). Objectives To evaluate INR stability in nonvalvular AF patients treated with warfarin anticoagulation, to evaluate thromboembolic or hemorrhagic complications, and to identify the group at higher risk for thromboembolic or hemorrhagic events. Methods Data from the medical records of 203 patients who received medical care at a tertiary hospital in Brazil were reviewed, and the time in therapeutic range (TTR) was calculated using the Rosendaal method. The possible TTR influencing factors were then analyzed, and the relationship between the TTR and thromboembolic or hemorrhagic events was calculated. The level of significance was 5%. Results The mean TTR was 52.2%. Patients with INR instability in the adaptation phase had a lower mean TTR (46.8%) than those without instability (53.9%). Among the studied patients, 6.9% suffered hemorrhagic events, and 8.4% had a stroke. The higher risk group for stroke and bleeding consisted of patients with INR instability in the adaptation phase. Conclusions The quality of anticoagulation in this tertiary hospital in Brazil is similar to that in centers in developing countries. Patients with greater INR instability in the adaptation phase evolved to a lower mean TTR during follow-up, had a 4.94-fold greater chance of stroke, and had a 3.35-fold greater chance of bleeding. Thus, for this patient group, individualizing the choice of anticoagulation therapy would be advised, considering the cost-benefit ratio.

Effect of Robot-Assisted Training on Unilateral Spatial Neglect After Stroke: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Several studies have shown that robotic devices can effectively improve motor function in stroke patients through limb activation. However, the effects of robot-assisted therapy on perceptual deficits after stroke is unclear. OBJECTIVE: This review aimed to evaluate the effectiveness of robotic limb activation in patients with unilateral spatial neglect (USN) after stroke. METHODS: In this systematic review, a literature search was performed using MEDLINE, EMBASE, CENTRAL, CINAHL, and LILACS databases without language restrictions. Randomized controlled trials (RCTs) and quasi-RCTs of robot-assisted therapy for USN after stroke were selected. Two reviewers independently assessed the risk of bias and certainty of the evidence of the included studies. RESULTS: A total of 630 studies were identified, including five studies for qualitative synthesis and four meta-analyses. The results of RCTs comparing robotic limb activation with a control group suggested an improvement in the degree of USN measured by the line bisection test (standardized mean difference [SMD], -0.64; 95% confidence interval [CI], -1.13 to -0.15; P = .01). There were no differences between the groups in the motor-free visual perception test 3rd edition (SMD, 0.27; 95% CI, -0.25-0.79; P = .31), star cancellation test (SMD, 0.26; 95% CI, -0.42-0.94; P = .54), Albert's test (SMD, -0.67; 95% CI, -2.01-0.66; P = .32), and Catherine Bergego Scale (SMD, -0.81; 95% CI, -2.07-0.45; P = .21). CONCLUSION: The study demonstrated that limb activation through robotic therapy can improve midline perception. However, there was no impact on tasks assessing visual scanning, functionality, or activities of daily living.

Progression of COVID-19 Among Black Pregnant Women: Population-Based Study.

The aim of this study was to evaluate the evolution of COVID-19 related to race/skin color among Brazilian pregnant women registered on the Sistema de Informação de Vigilância da Gripe (SIVEP Gripe). This is a population-based study, based on the data from SIVEP Gripe, with data collected at two time points, August 2020 and February 2021. From the complete database (575,935 cases on August 8, 2020 and 1,048,576 cases on January 2, 2021), the weeks 13 to 32 (563,851 cases) and 33 to 53 (469,241 cases) were selected. We selected cases of pregnant women with white, brown and black skin color and final evolution (1,884 and 1,286 cases). The final sample (939 and 858 cases) was defined by including participants who had all the targeted information recorded. The outcome variables were hospitalization, Intensive Care Unit (ICU) admission and COVID-19 deaths. The present study identified that there was a drop of approximately two-thirds in the proportion of pregnant women who required ICU care or died, when comparing the first and second periods. In the second period, black pregnant women had approximately five times higher risk of death compared to white and brown women.

The impact of disease changes and mental health illness on readapted return to work after repeated sick leaves among Brazilian public university employees.

Introduction: Health affects work absenteeism and productivity of workers, making it a relevant marker of an individual's professional development. Objectives: The aims of this article were to investigate whether changes in the main cause of the sick leaves and the presence of mental health illnesses are associated with return to work with readaptation. Materials and methods: A historical cohort study was carried out with non-work-related illnesses suffered by statutory workers of university campuses in a medium-sized city in the state of São Paulo, Brazil. Two exposures were measured: (a) changes, throughout medical examinations, in the International Classification of Diseases (ICD-10) chapter regarding the main condition for the sick leave; and (b) having at least one episode of sick leave due to mental illness, with or without change in the ICD-10 chapter over the follow-up period. The outcome was defined as return to work with adapted conditions. The causal model was established a priori and tested using a multiple logistic regression (MLR) model considering the effects of several confounding factors, and then compared with the same estimators obtained using Targeted Machine Learning. Results: Among workers in adapted conditions, 64% were health professionals, 34% had had changes in the ICD-10 chapter throughout the series of sick leaves, and 62% had diagnoses of mental health issues. In addition, they worked for less time at the university and were absent for longer periods. Having had a change in the illness condition reduced the chance of returning to work in another function by more than 30%, whereas having had at least one absence because of a cause related to mental and behavioral disorders more than doubled the chance of not returning to work in the same activity as before. Conclusion: These results were independent of the analysis technique used, which allows concluding that there were no advantages in the use of targeted maximum likelihood estimation (TMLE), given its difficulties in access, use, and assumptions.

Effect of transcranial direct current stimulation in addition to visuomotor training on choice reaction time and cognition function in amateur soccer players (FAST trial): A randomized control trial.

OBJECTIVES: This study aimed to evaluate the effect of anodal transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) in addition to visuomotor training (VMT) on choice reaction time (CRT) and cognitive function in amateur soccer players. DESIGN: Single-center, randomized, placebo-controlled, double-blind, parallel-group study. SETTING: Neuroscience and Motor Control Laboratory. PARTICIPANTS: Thirty Brazilian male amateur soccer players, aged 18-30 years. MAIN OUTCOME MEASURES: Participants were allocated to the intervention or control groups. Both groups performed VMT, but the intervention group additionally underwent anodal tDCS over the left dorsolateral prefrontal cortex (DLPFC; F3). The cathodal electrode was positioned in the right supraorbital region (Fp2). The tDCS was applied at 2 mA for 20 min for five consecutive sessions (24 h intervals). The VMT protocol was delivered during the application of tDCS and was composed of kicking a ball for 10 min (between the fifth and fifteenth minutes of the 20 min of tDCS application). The primary outcome was assessed based on changes in CRT during reaching (non-trained limb) and kicking (trained limb) tasks. Secondary outcomes were overall cognitive function measured by the Trail Making Test part A (TMT-A) and part B (TMT-B), and Digit Span Test forward (DSF) and backward (DSB) scores. All outcomes were evaluated before and after the intervention. RESULTS: In the primary outcomes, compared with the control group, the anodal tDCS combined with VMT group had greater reduction in CRT for the rectus femoris (p = 0.007) adjusted for age and baseline performance (F (1,26) = 22,23; p < 0,001) and for the triceps (p = 0.039) adjusted for training frequency (days/week) and baseline performance (F (1,26) = 5,70; p = 0,016). No differences were observed in the CRT of other muscles (anterior deltoid [p = 0.181], brachial biceps [p = 0.130], and vastus medialis [p = 0.074]). And, there were no differences between the groups in terms of cognitive function (TMT-A [p = 0.062]; TMT-B [p = 0.320]; DSF [p = 0.102]; DSB [p = 0.345]). CONCLUSION: Anodal tDCS over the left DLPFC in addition to visuomotor training of a functional task can be an efficient tool for athletes to decrease the CRT of the rectus femoris (trained limb) and triceps (non-trained limb); however, there were no differences between the groups in the others muscles (anterior deltoid, brachial biceps, and vastus medialis), and in terms of cognitive function.

Positividade de culturas por modalidades de banho no leito hospitalar: estudo ecológico / Positividad de culturas por modalidades de baño en cama hospitalaria: estudio ecológico / Culture positivity by hospital bath bed modalities: an ecological study

Resumo Objetivo Verificar positividade de culturas microbiológicas de pacientes hospitalizados, com prescrição de enfermagem para banho no leito, em três períodos disjuntos e sequenciais das modalidades de banho no leito: convencional (BLC), descartável (BLD) e descartável acrescido de clorexidina degermante à 2% (BLD-CX). Métodos Estudo ecológico, tipo séries temporais de 48 meses, em três períodos (P1=BLC; P2=BLD; P3=BLD-CX), com dados secundários de prontuário eletrônico, de pacientes que estiveram internados em hospital do estado de São Paulo, Brasil. Resultados Nos períodos de banhos descartáveis, o percentual de positividade foi, em média, 14,6% menor quando comparado aos meses cujo banho de leito foi convencional. No período de BLD-CX o percentual de positividade foi, em média, 19,3% menor quando comparado aos meses do período de BLC. Contudo, não há evidências de diferença no percentual de positividade entre o BLD (b = -14,6%; IC95% = (-18,9% a -10,3%) e o BLD-CX (b = - 19,3%; IC95% = (-24,4% a -14,22%). A cada ano a mais na idade média do paciente, o percentual de positividade aumenta, em média 0,3% (p=0,060). Não houve associação sazonal para positividades das culturas microbiológicas nas modalidades de banho. Conclusão A positividade de culturas microbiológicas, em pacientes com prescrição de enfermagem para banho no leito, é menor quando se utiliza as modalidades descartáveis. Recomenda-se adotar rotineiramente o BLD, deixando a prescrição de BLD-CX, somente para degermação da pele para procedimentos invasivos, operatórios e higienização das mãos de profissionais de saúde.

Resumen Objetivo Verificar los resultados positivos de culturas microbiológicas de pacientes hospitalizados, con prescripción de enfermería de baño en cama, en tres períodos disjuntos y secuenciales de las modalidades de baño en cama: convencional (BCC), descartable (BCD) y descartable con clorhexidina al 2 % (BCD-CX). Métodos Estudio ecológico, tipo series temporales de 48 meses, en tres períodos (P1=BCC; P2=BCD; P3=BCD-CX), con datos secundarios de historia clínica electrónica, de pacientes que estuvieron internados en hospital del estado de São Paulo, Brasil. Resultados En los períodos de baños descartables, el porcentaje de resultados positivos presentó un promedio 14,6 % inferior en comparación con los meses en que el baño en cama fue convencional. Durante el período de BCD-CX el porcentaje de resultados positivos fue, en promedio, 19,3 % inferior en comparación con los meses del período de BCC. Sin embargo, no hay evidencias de diferencias en el porcentaje de resultados positivos entre el BCD (b = -14,6 %; IC95 % = (-18,9 % a -10,3 %) y el BLD-CX (b = - 19,3 %; IC95 % = (-24,4 % a -14,22 %). Por cada año que se suma a la edad promedio del paciente, el porcentaje de resultados positivos aumenta en promedio 0,3 % (p=0,060). No se verificó una asociación estacional en las respuestas positivas de las culturas microbiológicas en las modalidades de baños. Conclusión Los resultados positivos de culturas microbiológicas de pacientes con prescripción de enfermería de baño en cama son menores cuando se utilizan las modalidades descartables. Se recomienda adoptar de forma rutinaria el BCD y dejar la prescripción de BCD-CX solo para la eliminación de los gérmenes de la piel en procedimientos invasivos, quirúrgicos e higienización de manos de los profesionales de salud.

Abstract Objective To verify microbiological culture positivity of hospitalized patients, with a nursing prescription for bed bath, in three disjoint and sequential periods of bed bath modalities: conventional (CBB), disposable (DBB) and disposable plus 2% chlorhexidine degerming (DBB-CX). Methods This is an ecological, time series study of 48 months, in three periods (P1=CBB; P2=DBB; P3=DBB-CX), with secondary data from electronic medical records of patients who were admitted to a hospital in the state of São Paulo, Brazil. Results In the periods of disposable baths, the percentage of culture positivity was, on average, 14.6% lower when compared to the months in which bed bath was conventional. In the DBB-CX period, the percentage of culture positivity was, on average, 19.3% lower when compared to the CBB period months. However, there is no evidence of difference in the percentage of culture positivity between DBB (b = -14.6%; 95%CI = (-18.9% to -10.3%) and DBB-CX (b = - 19.3%;95%CI = (-24.4% to -14.22%) For each year more in patients' mean age, the percentage of culture positivity increases by an average of 0.3% (p=0.060). There was no seasonal association for microbiological culture positivity in bath modalities. Conclusion Microbiological culture positivity in patients with a nursing prescription for bed bath is lower when disposable modalities are used. It is recommended to routinely adopt DBB, leaving the prescription of DBB-CX only for skin degermation for invasive and operative procedures and hand hygiene of health professionals.
