A inclusão da equipe de saúde bucal na Estratégia Saúde da Família: entraves, avanços e desafios

The aim of this study was to examine the procedures of primary dental health care performed by oral health teams (OHTs) adhering to the second cycle of the ‘National Programme for Improving Access and Quality of Primary Care’ (PMAQ-AB) in Brazil. A cross-sectional descriptive analysis was performed, across 23 dental procedures comprising preventive, restorative/prosthetic, surgical, endodontic and oral cancer monitoring. Descriptive analysis shows that most of the oral health teams carry out basic dental procedures. However, most of the time, they do not keep adequate records of suspected cases of oral cancer, diagnosis tests or follow-ups, and do not perform dental prosthetic procedures. Data also showed disparities in the average number of procedures performed in each Brazilian geographical region in 2013–2014, ranging from 13.9 in the northern to 16.5 in the southern and south-eastern regions, reinforcing the great social disparities between them. Brazilian regions with the highest volume of dental need deliver the lowest number of dental procedures. The need to tackle inequalities and further shape the supply of appropriate primary health care (PHC) is evident.

Comprehensiveness relates both to the scope of services offered and to a holistic clinical approach. The aim of this study was to identify the perception of Brazilian dentists regarding key concepts of comprehensiveness and its importance in primary health care oral health services performed in the public sector. Focus groups were conducted to explore three main concepts, 'patient welcoming', 'bonding' and 'quality of care', as well as their aspects. In total, there were four focus groups comprising seven general dentists, all of whom had at least two years of experience in primary care, from municipalities of varying sizes. Discussions of approximately 60 minutes were conducted, audio-recorded and transcribed. The data were analysed by qualitative thematic analysis, in line with the framework approach. The general dentists reported that they are aware that in the Brazilian Health System, the onset of patient care by primary health care services must happen through 'patient welcoming.' Nevertheless, they suggested that this action is often performed poorly due to the large volume of patients. Although they knew the importance of 'bonding', they realised that there is a lack of education preparing professionals to address interpersonal and social issues. They were aware that 'quality of care' is related to multiple factors. Comprehensiveness, as an approach in dental public health practices, needs to be enhanced, and there is evidence that primary care dentists are aware of the need for such an approach.

Objectives First, to assess the psychometric properties of key questions included in a public sector evaluation of primary dental care in Brazil; and second, to evaluate the performance of dental teams in relation to these items. Methods Secondary analysis of a national primary care dataset monitoring quality and access to dental care. Data were collected through face-to-face interviews with representatives of dental teams participating in the ‘National Programme for Improving Access and Quality of Primary Care’. Twenty-three mandatory questions about the dentists’ reported delivery of dental procedures were included in the analysis. Item Response Theory (IRT) modelling was applied to measure the psychometric properties of the instrument—level of difficulty and discrimination parameter of each item—and then to estimate dental team performance scores based on these parameters. Based on IRT, possible scores ranged from -4 to +4. Results Three of the 23 mandatory items were removed due to poor internal consistency, resulting in a scale of 20 items for assessing dental team performance. The results showed variation in procedures delivered by the dental teams; whilst more than a half of the procedures were executed by at least 80% of the dental teams, those relating to dentures (partial/total) and frenectomy (lingual/labial) were performed by less than 30%. Amongst the 20 items included in the model, those related to partial/total dentures and oral cancer follow-up presented higher levels of difficulty and were less frequently provided. The items relating to the treatment of deciduous teeth and access to the dental pulp of permanent teeth had the highest discrimination parameters and, consequently, greater weight in the performance’s score estimation; therefore, dental teams that did not perform these items had the lowest performance scores. In the present study, dental team performance scores ranged from -3.66 to +1.87 with a mean/median of -0.06/+0.01. Conclusion The findings suggest that whilst the items within the instrument demonstrated some potential to discriminate between poor and very poor teams, they were ineffective in discriminating between poor and good teams. Whilst Brazilian dental teams perform many mandatory procedures, variation in the nature of their delivery of care requires further investigation to enhance service provision to the population.

This study aimed to evaluate the psychometric properties of an instrument to assess comprehensiveness of care from dentists using a combination of classical test theory and item response theory. A 46-item instrument was developed and tested by a panel of experts, followed by a pilot test and administration to 187 primary care dentists in a large Brazilian city. The 46 items were evaluated using the following criteria: acceptability, internal consistency, temporal stability, inter-item correlation, and tetrachoric correlation. This evaluation led to a shortened version consisting of 11 items that met all the criteria previously described. The temporal stability was measured using Cohen's kappa, and all 11 items presented values greater than 0.5. The Cronbach's alpha value was 0.72. None of the 11 items had missing data on the distribution of responses, and the model considering the discrimination as varying fit the data better than the model considering discrimination as a constant parameter (p<0.001). Item characteristic curves showed that 54.5% of items could be considered difficult, i.e., only dentists with a good understanding of comprehensiveness responded favorably. The 11-item instrument to assess comprehensiveness of care by dentists is considered to have good psychometric properties.E v a l u a t i n g P s y c h o m e t r i c P r o p e r t i e s o f a n I n s t r u m e n t Addressing Comprehensiveness o f C a r e A m o n g D e n t i s t s
