Self-efficacy measurement instruments for individuals with coronary artery disease: A systematic review

INTRODUCTION

Over the past decade, there has been a heightened interest in evaluating self-efficacy among patients with coronary artery disease (CAD). A significant number of instruments have been developed and validated, yet the need remains to assess the quality of their studies and their properties.

OBJECTIVES

To evaluate the measurement properties and link the content extracted from self-efficacy instrument items for individuals with CAD to the International Classification of Functioning, Disability, and Health (ICF).

METHODOLOGY

The study was conducted following the Cochrane systematic review guidelines and COnsensus norms for Selection of health Measuring INstruments (COSMIN), registered under CRD42021262613. The search was carried out on MEDLINE (Ovid), Web of Science, EMBASE, and PsycINFO, including studies involving the development and validation of self-efficacy instruments for individuals with CAD, without language or date restrictions. Data extraction was performed in May 2022 and updated in January 2023 and all the steps of this review were carried out by two different collaborators and reviewed by a third when there were divergences. Modified Grading of Recommendations, Assessment, Development and Evaluation (GRADE) recommended by COSMIN was used to determine the quality of evidence as high, moderate, low, or very low. Instrument categorization was carried out per COSMIN recommendations, according to the construct of interest and study population into three categories (A, B, or C).

RESULTS

A total of 21 studies from 12 instruments were identified. The best-rated instruments received a recommendation of B, which means, additional validation studies are needed. Barnason Efficacy Expectation Scale (BEES) showed high-quality evidence for structural, construct, criterion, and internal consistency validity; Cardiac Self-Efficacy Scale (CSES) demonstrated high quality for content, structural, cross-cultural validity, and internal consistency; Self-efficacy for Appropriate Medication Use (SEAMS) achieved a high level for structural, criterion, and internal consistency validity; Cardiovascular Management Self-Efficacy Scale exhibited high-level validity for structural, criterion, construct, and internal consistency. The CSES showed content linkage with all domains of the ICF, as well as the highest number of linkages with the categories.

CONCLUSIONS

Instruments with a B-level recommendation hold potential for use. More studies assessing measurement properties are needed to reinforce or improve these recommendations. The CSES stands out as the most comprehensive instrument concerning the ICF.

Barriers to and facilitators of populational adherence to prevention and control measures of COVID-19 and other respiratory infectious diseases: a qualitative evidence synthesis

AIMS

To summarise the evidence on barriers to and facilitators of population adherence to prevention and control measures for coronavirus disease 2019 (COVID-19) and other respiratory infectious diseases.

METHODS

A qualitative synthesis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis and the Cochrane Effective Practice and Organization of Care: Qualitative Evidence Synthesis. We performed an electronic search on MEDLINE, Embase and PsycINFO from their inception to March 2023.

RESULTS

We included 71 studies regarding COVID-19, pneumonia, tuberculosis, influenza, pertussis and H1N1, representing 5966 participants. The measures reported were vaccinations, physical distancing, stay-at-home policy, quarantine, self-isolation, facemasks, hand hygiene, contact investigation, lockdown, infection prevention and control guidelines, and treatment. Tuberculosis-related measures were access to care, diagnosis and treatment completion. Analysis of the included studies yielded 37 barriers and 23 facilitators.

CONCLUSIONS

This review suggests that financial and social support, assertive communication, trust in political authorities and greater regulation of social media enhance adherence to prevention and control measures for COVID-19 and infectious respiratory diseases. Designing and implementing effective educational public health interventions targeting the findings of barriers and facilitators highlighted in this review are key to reducing the impact of infectious respiratory diseases at the population level.

Translation and cross-cultural adaptation of the Model Disability Survey (MDS) for Brazil

OBJECTIVE

This study has as objective the translation and cross-cultural adaptation of the Model Disability Survey (MDS), a World Health Organization instrument that provides comprehensive information on disability/functioning, for Brazil.

METHODS

This is a cross-sectional methodological study, carried out through five stages - initial translation, synthesis of translations, reverse translation, review by a specialist committee, and pre-test -, considering properties such as semantic, idiomatic, experimental, and conceptual equivalence. Translators, researchers, a mediating team, health professionals, a methodologist and a language specialist were needed to pass through the stages. Statistical analysis was produced from absolute and relative frequencies, measures of central tendency and dispersion, normality tests and content validity index (CVI) > 0.80.

RESULTS

The MDS has 474 items, which generated 1,896 analyzes of equivalence. Of these, 160 items had a CVI < 0.80 in at least one of the four types of equivalence and required adjustments. After adaptations and approval by the judges, the pre-final version went on to the pre-test with 30 participants from four regions of the Brazilian Northeast. Regarding this sample, 83.3% are women, single, with an average age of 33.7 years (SD 18.8), self-declared as black or brown, active workers, with technical education and living with three residents. Interviews lasted 123 minutes on average, where 127 health conditions were mentioned, and the most frequent cited were anxiety and back pain. Answers were analyzed and 63 items were cited as needing some adjustment, two of which were submitted for analysis by the committee because they presented a CVI < 0.80. The instrument, guide and presentation cards were adjusted after a new pre-test.

CONCLUSIONS

The MDS was translated and cross-culturally adapted to Brazilian Portuguese and showed adequate content validity.

Effects of home healthcare for adults with chronic respiratory diseases and post-COVID-19 syndrome on hospital bed turnover rate: a protocol of systematic review with meta-analysis

INTRODUCTION

Chronic respiratory diseases (CRDs) have a high prevalence, morbidity and mortality worldwide. After the COVID-19 pandemic, the number of patients readmitted after hospital discharge increased. For some populations, early hospital discharge and home healthcare may reduce health costs in patients treated at home when compared with those hospitalised. This study aims to systematically review the effectiveness of home healthcare for patients with CRDs and post-COVID-19 syndrome.

METHODS AND ANALYSIS

We will search on MEDLINE, CENTRAL, Embase and PsycINFO. We will include randomised controlled trials (RCTs) and non-RCT studies reported in full text and abstracts. No language restriction will be applied. We will include studies related to adults with a diagnosis of CRDs or post-COVID-19 syndrome that compared in-patient hospital care with any home healthcare. We will exclude studies with participants with neurological, mental diseases, cancer or pregnant women. Two review authors will screen abstracts and select the eligible studies. To investigate the risk of bias, we will use the Cochrane 'Risk of Bias' tool for RCT, and the Risk of Bias In Non-randomised Studies-of Interventions for non-RCT. We will use the five Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) considerations to assess the quality of the evidence. Patients and the public will be involved in the preparation, execution and implementation phases of the review.

ETHICS AND DISSEMINATION

No ethical approval is required because only published data will be analysed. The publication of the results in peer-reviewed journals and at relevant conferences will guide the direction of future research in the field and healthcare practice. The results will also be disseminated in plain language on social media to disseminate the knowledge to society and the public interested in the topic.

Co-Design of an Intervention to Increase the Participation in Leisure Activities Including Adolescents with Cerebral Palsy with GMFCS Levels IV and V: A Study Protocol

The participation of adolescents with cerebral palsy (CP) within the community is reduced compared to their peers and is a barrier to their socialization, self-determination and quality of life. Patient and Public Involvement (PPI) is a key strategy for successful interventions, especially when involvement of the stakeholders takes place at all stages of the research. Co-design can be crucial for success as researchers, patients with CP and their families work together to bring the necessary elements to the interventions to be designed. The objectives will be: (1) To co-design an intervention aimed at improving the participation of adolescents with significant motor disabilities within the community in partnership with adolescents with CP, families and rehabilitation professionals. (2) To assess the feasibility of the co-design process in partnership with interested parties. The study will be based on Participatory Action Research (PAR) and will be held in Spain and Brazil. In both countries, the study will be carried out remotely with nine adolescents aged 12 to 17 years with CP, Gross Motor Function Classification System (GMFCS) levels IV-V, their families and six health professionals (physiotherapists and occupational therapists). Different dialogue groups will be created to involve adolescents, families and health professionals to the research's project. To manage their involvement in the co-design process, the Involvement Matrix (IM) will be used, and according to the IM phases, four steps will be included in the research: (1) Preparation; (2) Co-design; (3) Analysis: results of the intervention protocol and the study's feasibility and (4) Dissemination of results. Partnering with the public to design an intervention to improve participation can bring better results compared to protocols designed only by health professionals. In addition, it will allow for knowing the needs of adolescents with CP in terms of participation within the community. The study will also explore which roles were chosen by all participants and how they felt while actively participating in the process of co-designing an intervention protocol and their own perspectives on the use of the involvement matrix.

Effects of respiratory physiotherapy interventions on pulmonary mechanics of newborns: a protocol for a systematic review

INTRODUCTION

Although respiratory physiotherapy techniques may reduce respiratory load in newborns, manual contact with the ribcage may interfere with pulmonary mechanics. Therefore, this systematic review aims to evaluate the effects of conventional and non-conventional respiratory physiotherapies on pulmonary mechanics of newborns.

METHODS AND ANALYSIS

We will search PubMed, LILACS, SciELO, ScienceDirect, Cochrane Central and Web of Science databases. Searches will be conducted from September 2022. We will include randomised clinical trials reporting thoracoabdominal synchrony, lung volumes and capacities, respiratory discomfort and pain in newborns aged between 1 hour and 28 days and admitted to neonatal intensive care units. We will exclude studies not fully available or incomplete and studies conducted with newborns presenting structural alterations. Two independent researchers will perform the study selection, data extraction and quality assessment. After consensus, one reviewer will proceed with the process. We will include studies published in English or Portuguese, without publication date restriction. An overview of the included studies and extracted information will be reported and the quality of studies will be assessed. A meta-analysis will be conducted if data regarding between-group comparisons are available.

ETHICS AND DISSEMINATION

Ethics approval is not required for this systematic review. Results will be presented in journals and national and international conferences, and findings will be shared on social media using accessible language.

Self-efficacy instruments for individuals with coronary artery disease: a systematic review protocol

INTRODUCTION

Self-efficacy is associated with management of diseases, psychological well-being, improved quality of life and rehabilitation adherence. Several instruments related to behaviour or specific disease (eg, coronary artery disease (CAD)) assess self-efficacy. The evaluation of cardiac self-efficacy in individuals with CAD will support healthcare professionals to improve self-efficacy via interventions; therefore, a suitable instrument is crucial. This systematic review aims to assess measurement properties, methodological quality and content of outcome measures of cardiac self-efficacy instruments for individuals with CAD.

METHODS AND ANALYSIS

The study has been developed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol and Consensus Norms for Selection of Health Measuring Instruments (COSMIN). The following databases will be searched: MEDLINE (Ovid), Web of Science, EMBASE and PsycINFO. Studies assessing measurement properties of cardiac self-efficacy instruments for individuals with CAD will be included. No date or language restrictions will be applied to the search. Two independent authors will be responsible for assessing the eligibility of studies. Methodological quality of studies will be assessed using the COSMIN RoB Checklist, and the Grading of Recommendations, Assessment, Development and Assessment will be used to assess the quality of each study. Two authors will independently evaluate the content of instruments and link this to the International Classification of Functioning, Disability and Health.

ETHICS AND DISSEMINATION

This study does not require ethics committee approval since it is based on previously published data. Evidence from this systematic review will be disseminated through publication in peer-reviewed journals and presentation at scientific conferences.

Translation, cross-cultural adaptation and psychometric evaluation of the Brazilian version of the Cystic Fibrosis Knowledge Scale (CFKS)

BACKGROUND

Information on the level of knowledge about cystic fibrosis (CF) among affected people and their families is still scarce.

OBJECTIVE

This study aimed to translate, cross-culturally adapt and analyze the psychometric properties of the Brazilian version of Cystic Fibrosis Knowledge Scale (CFKS).

MATERIALS AND METHODS

The translation and cross-cultural adaptation involved the stages of translation, synthesis of translations, reverse translation, synthesis of reverse translations, review by a multi-professional committee of experts and pre-testing. The reliability, viability, construct, predictive, concurrent and discriminant validity were investigated.

RESULTS

The sample consisted of 40 individuals with cystic CF, 47 individuals with asthma, 242 healthcare workers and 81 students from the health area. The Brazilian version of the CFKS presented high internal consistency (α = 0.91), moderate floor and ceiling effects, without differences in the test-retest scores. An analysis of factorial exploration identified three dimensions. Confirmatory factor analysis led to an acceptable data-model fit. There was good predictive validity, with a difference in the scores among all the evaluated groups (p <0.001), as well as good discriminant validity since individuals with asthma had greater knowledge of asthma compared to CF (r = 0.401, p = 0.005; r2 = 0.162). However, there was no difference between the diagnosis time and knowledge about CF (r = -0.25, p = 0.11; r2 = 0.06), either between treatment adherence and knowledge about CF (r = -0.04, p = 0.77; r2 = 0.002).

CONCLUSION

The Brazilian version of the CFKS indicated that the scale is able to provide valid, reliable and reproducible measures for evaluating the knowledge about CF.

Buteyko method for people with asthma: a protocol for a systematic review and meta-analysis

INTRODUCTION

Buteyko method is recommended as a non-pharmacological treatment for people with asthma. Although the worldwide interest in the Buteyko method, there is a paucity of studies gathering evidence to support its use. Therefore, we aim to conduct a systematic review and meta-analysis to assess the effects of the Buteyko method in children and adults with asthma.

METHODS AND ANALYSIS

We will search on Cochrane Central Register of Controlled Trials, MEDLINE, Embase, US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov and WHO International Clinical Trials Registry Platform for studies focusing on the Buteyko method for children and adults with asthma. The searches will be carried out in September 2021 from database's inception to the present. We will include randomised controlled trials comparing Buteyko method alone with asthma education or inactive control intervention. There will be no restriction on language. Primary outcomes include quality of life, asthma symptoms and adverse events/side effects. Two review authors will independently screen the studies for inclusion and extract data. We will assess the quality of the included studies using the 'Risk of Bias' tool. The certainty of the evidence will be assessed using the GRADE approach. Data synthesis will be conducted using Review Manager software. Reporting of the review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance and the Cochrane Handbook for Systematic Reviews of Interventions.

ETHICS AND DISSEMINATION

This study will assess and provide evidence for the use of the Buteyko method in people with asthma. We will analyse secondary data and this does not require ethics approval. The findings will be published in peer-reviewed journals, at relevant conferences and will be shared in plain language in social media. Moreover, the findings of this review could guide the direction of healthcare practice and research.

Relationship between anxiety symptoms, clinical control and quality of life of children with asthma: A cross-sectional study

OBJECTIVE

To investigate the relationship between anxiety symptoms and factors related to clinical control and quality of life of children with asthma aged 7-12 years.

METHODS

A cross-sectional comparative study involving children recruited from a reference center for asthma treatment in the city of Natal-RN. Diagnosis, control and severity were performed following GINA recommendations (2019). Sociodemographic information and spirometry results from a bronchodilator test were collected. Modified Fisher's scale, clinical control questionnaires (c-ACT and ACT), quality of life assessment (PAQLQ) (total score and domains) and anxiety symptoms assessment (SCAS) (total score and domains) were applied.

RESULTS

The sample consisted of 42 children with asthma. Symptoms of social phobia (as identified by SCAS), and household head education were related to clinical asthma control (p = .006; R ²  = .19). Total SCAS score, guardian's education and physical activity were related to total PAQLQ (p < .0001; R ²  = .33). SCAS was related to the activity limitation domain of PAQLQ (p = .004; R ²  = .17). SCAS, gender, and physical activity were related to the PAQLQ symptoms domain (p = .003; R ²  = .32). The guardian's education, physical activity practice, and the symptoms of separation anxiety, panic attack and agoraphobia (as identified by SCAS) were related to the emotional domain of PAQLQ (p = .004; R ²  = .45).

CONCLUSION

The present study shows evidence of an association between anxiety symptoms, poorer clinical control, and health-related quality of life in children with asthma.

Barriers and facilitators to populational adherence to prevention and control measures of COVID-19 and other respiratory infectious diseases: a rapid qualitative evidence synthesis protocol

INTRODUCTION

The current COVID-19 pandemic has increased the need for populational adherence to measures for the prevention and control of respiratory infectious diseases. However, their effectiveness depends on the population's preventive behaviour, which may be divergent from public policies. Therefore, this study aims to summarise and evaluate the evidence on barriers and facilitators to populational adherence to prevention and control measures in COVID-19 and other respiratory infectious diseases.

METHODS AND ANALYSIS

We will search on MEDLINE, Embase and PsycINFO for studies focusing on adults receiving protective behaviour recommendations to combat COVID-19 and other respiratory infectious diseases. The searches will be carried out from database's inception to the present. We will include studies that use qualitative methods in their data collection and analysis and studies that use mixed methods if they include any qualitative methods of analysis. Studies published in English, Portuguese and Spanish will be included. Two review authors will independently screen the studies for inclusion and extract data. We will assess the quality of the included studies using the Critical Skills Appraisal Programme tool. For the assessment of the confidence in the synthesised findings, we will use the GRADE-Confidence in the Evidence from Reviews of Qualitative research. Data analysis will be conducted using the best-fit framework approach based on adapted dimensions from the Health Belief Model and the Behaviour Change Wheel.

ETHICS AND DISSEMINATION

This study will be conducted on published evidence, and thus, no ethical approval is required. The findings of this rapid qualitative evidence synthesis will be disseminated to academic audiences, health policy-makers and the general population. We will publish the results in peer-reviewed journals, present our findings in conferences, and disseminate results via social media. We also aim to present the research findings in plain language and disseminate the knowledge to the general population to increase public interest.

Go Zika Go: A Feasibility Protocol of a Modified Ride-on Car Intervention for Children with Congenital Zika Syndrome in Brazil

Children with congenital Zika syndrome (CZS) present severe motor disability and can benefit from early powered mobility. The Go Zika Go project uses modified ride-on toy cars, which may advance the body functions, activities, and participation of children. This paper describes the study protocol aiming to assess the feasibility of a modified ride-on car intervention for children with CZS in Brazil. A mixed-methods design with a multiple 1-week baseline, 3-month intervention, and 1-month follow-up will be implemented. Modified ride-on car training sessions will be conducted three times a week at the participants’ home or in the clinic. The primary outcome will be a narrative description of study feasibility (photovoice method, focus groups, parent feasibility questionnaire and assessment of learning powered mobility). Secondary outcomes will be switch activation, driving sessions journal, social-cognitive interactions, mobility (pediatric evaluation of disability inventory computer adaptive test), goal attainment scaling (GAS), and participation (young children’s participation and environment measure). Go Zika Go is expected to be viable and to improve function, activity, and participation of children with CZS, providing a low-cost, evidence-based rehabilitation option that will be relevant to early child development in a global perspective.

Psychometric evaluation of the Brazilian version of the pediatric asthma control and communication instrument

BACKGROUND

There is a lack of questionnaires capable of evaluating the clinical control of Brazilian children and adolescents with asthma over a wide age range. The Pediatric Asthma Control and Communication Instrument (PACCI) has been validated, but only with English- and Spanish-speaking children in the United States.

OBJECTIVES

To evaluate the psychometric properties of the Brazilian version of the PACCI questionnaire.

METHODS

A cross-sectional psychometric study conducted with children and adolescents aged 01 to 19 years with a clinical diagnosis of asthma, and their respective parents/guardians. The following assessments were conducted: socioeconomic status; clinical control using the Childhood Asthma Control Test (c-ACT), Asthma Control Test (ACT); caregiver quality of life using the Pediatric Asthma Caregivers Quality of Life Questionnaire (PACQLQ); and pulmonary function test (spirometry). Validity was evaluated as follows: exploratory and confirmatory factor analysis; Cronbach's alpha analysis (α); floor and ceiling effects; receiver operator characteristic curve analysis.

RESULTS

A total of 128 participants were included, most of them male (54.7%). The Brazilian version of PACCI had adequate internal consistency (α = .76) and moderate floor and ceiling effects. The internal structure presented acceptable adjustment indices, considering the extraction of four factors. The factors presented adequate α values. Asthma control factor 1 correlated with c-ACT/ACT and PACQLQ. Control domain scores greater than four points (sum of score) and above 1 point (problem index) were indicative of uncontrolled asthma.

CONCLUSION

The Brazilian version of PACCI was able to provide valid and reliable measures in evaluating the clinical control of asthma in Brazilian children and adolescents.

Patient- and proxy-reported outcome measures instruments for the assessment of asthma control among adult and pediatric population: A protocol for systematic review

BACKGROUND

Asthma is a chronic airways inflammatory disease considered as a serious public health problem. Since asthma is a lifelong condition, the assessment of its control is important to achieve a better self-management. Based on the advances of the assessment tools, many instruments have been developed to assess asthma control. Therefore, this systematic review aims to assess the measurement properties, the methodological quality, and the content of outcome measures of the available patient- and proxy-reported asthma control instruments.

METHODS

This is a systematic review protocol of the measurement properties of asthma control patient- and proxy-reported outcome instruments. Database searches will be primarily performed on MEDLINE, EMBASE, Web of Science, ScienceDirect and PsycINFO. A manual search of websites considered databases for questionnaires and reference lists will also be conducted. The methodological quality of the studies and the measurement properties will be critically appraised using the COSMIN risk of bias (RoB) checklist. The content of all measurement instruments will be compared based on the International Classification of Functioning, Disability and Health framework.

RESULTS

The findings from this systematic review will be disseminated through publication in a peer-reviewed journal and presented at scientific conferences.

CONCLUSION

The proposed systematic review will produce a comprehensive evaluation of the measurement properties of the currently available asthma control instruments for both adult and pediatric populations. We aim to help researchers and practitioners in their choice of an adequate instrument and to highlight the gaps in currently available tools.

Effects of aerobic interval training on glucose tolerance in children and adolescents with cystic fibrosis: a randomized trial protocol

Background

Individuals with cystic fibrosis (CF) may develop CF-related diabetes (CFDR). This comorbidity is related to a poorer quality of life, microvascular complications, a decline in lung function, and an increase in exacerbations, as well as delayed growth and puberty. Evidence exists that physical exercise contributes to glycemic control in individuals with non-CF-related diabetes. This exercise is usually continuous with moderate intensity and long duration, which can cause muscle dyspnea and fatigue in CF individuals. Aerobic interval training (AIT) emerges as a safe and effective alternative for treating these individuals. The objective of this study is to evaluate the effects of AIT on glucose tolerance in children and adolescents with CF.

Methods

This study will be a two-arm, prospectively registered, randomized controlled trial with blind assessors and twenty 6- to 18-year-old individuals with cystic fibrosis (CF) from two different Brazilian states. People with CF will be randomly allocated to either the experimental or control group using block randomization, stratified by puberty stage,. Participants from both groups will receive an educational intervention and will be asked to continue their usual daily treatment for the full duration of the study. Those in the experimental group will perform AIT on a cycle ergometer at home three times a week, for 8 consecutive weeks. The sample characterization will include an assessment of puberty stage, socioeconomic status, dyspnea, and anthropometry. The primary outcome will be the change in glucose tolerance, while the secondary outcomes will include lung function, exercise tolerance, respiratory muscle strength, quality of life, and CF exacerbations. All outcomes will be assessed at baseline, week 9, and week 17.

Discussion

This is the first study to evaluate the effects of AIT on glucose tolerance in children and adolescents with CF. This study will serve as a basis for guiding clinical practice and decision-making in treating glucose intolerance and CF-related diabetes (CFRD) in children and adolescents with CF.

How data provided by the Brazilian information system of primary care have been used by researchers

In this article, we have investigated how researchers use the data provided by the Brazilian Information System of Primary Care . We also searched, for the first time, studies that evaluated the quality and reliability of the information provided by the Primary Care Information System. An integrative review of the literature was performed using the keywords 'information systems, primary care and SIAB' on search databases, and 53 of 174 articles were selected. These publications were classified into two large subgroups: those using the Primary Care Information System as 'data source' and those that took it as the 'object of study'. The first group included 35 studies, 18 of which used demographic and social health data records, and nine described data about diseases, specifically hypertension and diabetes. These data were used by researchers for association with health indicators (20%) or comparison with other information systems (17%), sample or population calculus (9%), estimation of prevalence and characterization of the epidemiological profile of a population (26%) or, more generally, to carry out the assessment of health status (29%). The Primary Care Information System as the 'object of study' group included 18 works, describing the knowledge and practices of professionals in relation to the information system. These researchers pointed out issues in the process of production and information consolidation, mainly due to the lack of training and supervision of community health workers and bureaucratization of their work process. Although some issues in the quality of data provided by the Primary Care Information System were reported by researchers, these findings were not corroborated by two studies that assessed the reliability of information disclosed by this system. Despite changes in the Brazilian health policies, the issue of data quality in health information systems continues to be a challenge preventing data from being used for decision-making and knowledge production.

Reliability of information on people with disabilities gathered by community health workers in highly consanguineous communities of Northeastern Brazil

BACKGROUND

In Brazil, community health workers have gathered monthly information on people with disabilities to maintain the Primary Care Information System since 1998; however, few studies have used this database for scientific or public health policy purposes.

OBJECTIVES

This study aimed to evaluate the reliability of information on people with disabilities gathered by community health workers in primary care services.

METHOD

This was a cross-sectional population-based study conducted in two highly consanguineous communities, involving a population of 18,458 inhabitants in Northeastern Brazil. To study the prevalence of people with disabilities, estimations performed by health workers were compared with those obtained by researchers who interviewed 15.6% of the total population. To study the agreement of the information, data on 106 people with disabilities completed independently by researchers and health workers were compared to evaluate the degree of agreement for 28 variables analysed. Kappa statistics (κ) were used to calculate the inter-rater agreement.

RESULTS

The prevalence of disability estimated by community health workers was 3.01 and 2.00% for city A and B, respectively, while the percentages obtained by researchers were 6.72 and 5.65%, respectively, showing an underestimation of prevalence according to community health workers. The Kappa index value obtained for all data analysed (2,589 items excluding losses) was 0.808 (p < 0.01), indicating an almost perfect consistency of information collected by health workers compared to by researchers.

CONCLUSION

Community health workers collected information with a high degree of reliability, although the identification of the prevalence of disabled individuals was potentially impaired due to the work process.

[Assessment of competencies of community health workers for epidemiological data collection]

The scope of this study was to assess competencies in terms of reading, comprehension and problem-solving using educational material created for epidemiological research on people with disabilities. A form with twenty multiple-choice questions was prepared and distributed to a sample of 348 community health workers (CHWs) in the State of Paraíba. The socioeconomic profile revealed that, within the sample, most of these CHWs are female, between 30-49 years of age, married or in a stable relationship, with two children and have graduated from high school. Over 98% of CHWs are government employees and more than half have been working for more than eight years in the same community, predominantly in the urban area. The score for overall performance evaluation ranged from 33 to 60 points, with the mean score of 53.44 ± 4.88 points. This means that the CHWs were able to resolve over 65% of the questions properly. The overall performance was positively correlated with education and negatively with age, having children and the time taken to complete high school education. The overall results indicate the increasing professionalization and education of the CHWs and their potential role as collaborators in basic scientific research to make generalizations about public health.
