RESUMO

Background: Recent guidelines on opportunistic prostate cancer screening conclude that the decision to screen with prostate-specific antigen should be made by each patient individually together with the clinician. However, there is evidence of a lack of clinicians' awareness of prostate cancer screening. This study sought to assess the recent evidence of clinicians' knowledge, beliefs, and practice regarding opportunistic prostate cancer screening comparing urologists and generals practitioners. Methods: A systematic search was conducted in 3 online databases: MEDLINE, Web of Science and EMBASE (from January 1, 2015, to January 9th, 2023). Studies that explored clinicians' knowledge, beliefs, and practices regarding opportunistic prostate cancer screening were included. Studies were assessed for quality reporting according to the Strengthening the Reporting of Observational studies in Epidemiology guidelines. Results: A total of 14 studies met the inclusion criteria: ten studies included primary care health professionals, three studies included urologists, and one study included both. Studies involving general practitioners showed a generally low level of awareness of the recommended uses of the test, and urologists showed a greater knowledge of clinical practice guidelines. General practitioners' opinion of prostate-specific antigen was generally unfavourable in contrast to urologists' who were more likely to be proactive in ordering the test. Less than half of the included studies evaluated shared-decision making in practice and 50% of clinicians surveyed implemented it. Conclusion: General practitioners had less knowledge of prostate cancer risk factors and clinical practice guidelines in the use of PSA than urologists, which makes them less likely to follow available recommendations. A need to carry out education interventions with trusted resources based on the available evidence and the current guidelines was identified.

RESUMO

Objective: To identify barriers and facilitators of the implementation of shared decision-making (SDM) on PSA testing in primary care. Design: Systematic review of articles. Data sources: PubMed, Scopus, Embase and Web of Science. Eligibility criteria: Original studies published in English or Spanish that assessed the barriers to and facilitators of SDM before PSA testing in primary care were included. No time restrictions were applied. Data extraction and synthesis: Two review authors screened the titles, abstracts and full texts for inclusion, and assessed the quality of the included studies. A thematic synthesis of the results were performed and developed a framework. Quality assessment of the studies was based on three checklists: STROBE for quantitative cross-sectional studies, GUIDED for intervention studies and SRQR for qualitative studies. Results: The search returned 431 articles, of which we included 13: five cross-sectional studies, two intervention studies, five qualitative studies and one mixed methods study. The identified barriers included lack of time (healthcare professionals), lack of knowledge (healthcare professionals and patients), and preestablished beliefs (patients). The identified facilitators included decision-making training for professionals, education for patients and healthcare professionals, and dissemination of information. Conclusions: SDM implementation in primary care seems to be a recent field. Many of the barriers identified are modifiable, and the facilitators can be leveraged to strengthen the implementation of SDM.

RESUMO

BACKGROUND: Type 2 Diabetes (T2DM) prevalence is increasing in low- and middle-income countries along with high levels of obesity which vary according to socioeconomic and contextual characteristics. We aim to estimate the prevalence of T2DM and obesity in men and women in a hard-to-reach rural area in northern Ecuador considering socio-demographic characteristics. METHODS: Cross-sectional descriptive study based on a population-based survey in the Eloy Alfaro health district of Esmeraldas between October 2020 and January 2022. We collected sociodemographic information and risk factors for non-communicable diseases with an adapted version of the STEPS survey, performed oral glucose tolerance tests, biochemistry and took physical measurements. We estimated the prevalence of T2DM, obesity, and calculated Odds Ratios (OR) with confidence intervals by logistic regression in Stata v.15. RESULTS: The overall prevalence of T2DM was 6.8% (CI95%: 4.9-8.7), markedly higher among women compared to men (10.4%, CI95% 7.3-13.4%, compared 2.0%, CI95% 0.4-3.7% respectively). The risk of having T2DM in women was 5 times higher than in men adjusting for age, ethnicity, employment, household earnings and obesity (OR: 5.03; 95%CI: 1.68-15.01). Regarding age, the risk of T2DM increased by 6% per year (adjusted OR: 1.06; 95%CI: 1.03-1.08). Obesity prevalence was 30.8% (CI95%: 27.3-34.3), in women was nearly three times higher than in men (43.2% CI95%: 38.2-48.2, compared to 14.7% prevalence, CI95%: 10.6-18.8). Indigenous women had a lower prevalence of obesity compared with the Afro-Ecuadorian women (OR: 0.05; 95%CI: 0.02-0.18) after adjusting for age, employment status, household earnings and setting. CONCLUSION: We found alarming differences between the prevalence of T2DM and obesity in women and men that may be explained by gender roles, exacerbated in the rural context. Health promotion measures with a gender perspective should be adapted according to the characteristics of isolated rural contexts.

RESUMO

This qualitative study aims to explore how the COVID-19 pandemic impacted healthcare access for patients with chronic conditions in Ecuador from the patient's perspective. We interviewed 19 patients diagnosed with arterial hypertension or type 2 diabetes in rural and urban areas of Ecuador during August and September 2020. We used the Framework Method to analyse the interview transcripts with ATLAS.Ti 8.4 and organised the ideas discussed using categories from the World Health Organization Commission on the Social Determinants of Health conceptual framework. Reorganization of health services during the pandemic meant that patients with arterial hypertension or diabetes could no longer attend face-to-face appointments for disease follow-up. System failures related to medication supply led to increased out-of-pocket payments, which, together with reduced or absent earnings, and in a context with limited social protection policies, meant that patients frequently went for prolonged periods without medication. Rural health initiatives, support from family and use of traditional medicine were reported as ways to manage their chronic condition during this time. Barriers to disease management disproportionately affected individuals with low socioeconomic positions. Stock shortages, lack of protective labour policies and limited reach of anticipatory policies for health emergencies likely worsened pre-existing health inequities in Ecuador.

RESUMO

BACKGROUND: There is general agreement regarding the relevance of community involvement in public health policy, practice, and research to reduce health inequities. OBJECTIVE: This review aims to analyse the experiences of community engagement in public health actions, with particular attention to methodologies used and how community participation is articulated. METHOD AND ANALYSIS: We searched the Web of Science, EBSCO, and ProQuest for scientific articles published in peer-reviewed journals. We recorded methodological aspects, the approach to equity, actors that participated in the actions, and participation of the community in different phases (agenda setting, design, implementation, and evaluation). RESULTS: Of 4331 records, we finally included 31 studies published between 1995 and 2021. Twelve studies referred to Community-Based Participatory Research as the framework used. The actions addressed equity, mainly by tackling economic vulnerability (n = 20, 64%) and racial discrimination (n = 18, 58%). Workshops were the most used method. Participation was frequently observed in the design and implementation phases of the action, but it was reduced to community feedback in the evaluation. CONCLUSIONS: Co-created public health actions offer the opportunity to reduce health inequity and promote social change; yet, further effort is needed to involve communities in the entire cycle of decision making.

RESUMO

(1) Background: The frequency of imaging tests grew exponentially in recent years. This increase may differ according to a patient's sex, age, or socioeconomic status. We aim to analyze the impact of the Council Directive 2013/59/Euratom to control exposure to radiation for men and women and explore the impact of patients' age and socioeconomic status; (2) Methods: The retrospective observational study that includes a catchment population of 234,424. We included data of CT, mammography, radiography (conventional radiography and fluoroscopy) and nuclear medicine between 2007-2021. We estimated the associated radiation effective dose per test according using previously published evidence. We calculated a deprivation index according to the postcode of their residence. We divided the study in 2007-2013, 2014-2019 and 2020-2021 (the pandemic period). (3) Results: There was an increase in the number of imaging tests received by men and women after 2013 (p < 0.001), and this increase was higher in women than in men. The frequency of imaging tests decreased during the pandemic period (2020-2021), but the frequency of CT and nuclear medicine tests increased even during these years (p < 0.001) and thus, the overall effective mean dose. Women and men living in the least deprived areas had a higher frequency of imaging test than those living in the most deprived areas. (4) Conclusions: The largest increase in the number of imaging tests is due to CTs, which account for the higher amount of effective dose. The difference in the increase of imaging tests carried out in men and women and according to the socioeconomic status could reflect different management strategies and barriers to access in clinical practice. Given the low impact of the available recommendations on the population exposure to radiation and the performance of high-dose procedures such as CT, deserve special attention when it comes to justification and optimization, especially in women.

RESUMO

Work-related communication volume within the United Kingdom's National Health Service (NHS) has had little systematic research previously. The impact of communication volume on work-life balance of healthcare staff in the NHS is also not known and has not been an area of focus or governance. COVID-19 led to a shift to non-physical work, with greater reliance on digital communication for clinical decision making. We sought to elucidate the relationship between communication, work-life balance, and COVID-19. An online survey was conducted to assess the platforms used to communicate professionally, the volume of and time spent on work-related communications, how this has changed from before to during COVID-19, and the effect on work-life balance. A total of 3047 healthcare staff provided consent and evaluable data. Emails were reported as the most frequently used communication tool, and the majority of staff asked, reported increased work-related communications due to COVID-19. Staff estimated receiving 14 emails on an average day before COVID-19. During the pandemic, staff estimated getting approximately 17 emails on an average day and 29 emails on a busy day. Work communications reportedly took up increased amounts of family and home time during COVID-19. A large proportion (36%) of staff were unable to switch off from work-related communications already before COVID-19, worsening (57%) during the pandemic. Work-related digital communication is a vital component of working in the NHS. We provide the first detailed data on the types, volume, and impact of such communication on NHS staff during the COVID-19 pandemic, compared to pre-pandemic levels. We found that 82% of staff support the need for NHS guidance on work-related communications to help manage overload, protect emotional wellbeing, and increase resilience. Further work is urgently needed in this area to tackle the negative impact of communication technologies (technostress) on work-life balance to reduce staff stress, burnout, and turnover or early retirement of some staff.

RESUMO

Background: Opportunistic prostate-specific antigen (PSA) screening may reduce prostate cancer mortality risk but is associated with false positive results, biopsy complications and overdiagnosis. Although different organisations have emphasised the importance of shared decision making (SDM) to assist men in deciding whether to undergo prostate cancer screening, recent evaluations show that the available decision aids fail to facilitate SDM, mainly because they do not consider the patients' perspective in their design. We aim to systematically develop and test a patient decision aid to promote SDM in prostate cancer screening, following the Knowledge to Action framework. Methods: (1) Feasibility study: a quantitative survey evaluating the population and clinician (urologists and general practitioners) knowledge of the benefits and risks derived from PSA determination and the awareness of the available recommendations. Focus groups to explore the challenges patients and clinicians face when discussing prostate cancer screening, the relevance of a decision aid and how best to integrate it into practice. (2) Patient decision aid development: Based on this data, an evidence-based multicomponent SDM patient decision aid will be developed. (3) User-testing: an assessment of the prototype of the initial patient decision aid through a user-testing design based on mix-methods (questionnaire and semi-structured review). The decision aid will be refined through several iterative cycles of feedback and redesign. (4) Validation: an evaluation of the patient decision aid through a cluster-randomised controlled trial. Discussion: The designed patient decision aid will provide balanced information on screening benefits and risks and should help patients to consider their personal preferences and to take a more active role in decision making. Conclusions: The well-designed patient decision aid (PDA) will provide balanced information on screening benefits and risks and help patients consider their personal preferences.

RESUMO

We aimed to review strategies for identifying SARS-CoV-2 infection before the availability of molecular test results, and to assess the reporting quality of the studies identified through the application of the STARD guideline. We screened 3,821 articles published until 30 April 2021, of which 23 met the inclusion criteria: including at least two diagnostic variables, being designed for use in clinical practice or in a public health context and providing diagnostic accuracy rates. Data extraction and application of STARD criteria were performed independently by two researchers and discrepancies were discussed with a third author. Most of the studies (16, 69.6%) included symptomatic patients with suspected infection, six studies (26.1%) included patients already diagnosed and one study (4.3%) included individuals with close contact to a COVID-positive patient. The main variables considered in the studies, which included symptomatic patients, were imaging and demographic characteristics, symptoms, and lymphocyte count. The values for area under the receiver operating characteristic curve (AUC)ranged from 53-97.4. Seven studies (30.4%) validated the diagnostic model in an independent sample. The average number of STARD criteria fulfilled was 17.6 (maximum, 27 and minimum, 5). High diagnostic accuracy values are shown when more than one diagnostic variable is considered, mainly imaging and demographic characteristics, symptoms, and lymphocyte count. This could offer the potential to identify individuals with SARS-CoV-2 infection with high accuracy when molecular testing is not available. However, external validation for developed models and evaluations in populations as similar as possible to those in which they will be applied is urgently needed. IMPORTANCE According to this review, the inclusion of more than one diagnostic test in the diagnostic process for COVID-19 infection shows high diagnostic accuracy values. Imaging characteristics, patients' symptoms, demographic characteristics, and lymphocyte count were the variables most frequently included in the diagnostic models. However, developed models should be externally validated before reaching conclusions on their utility in practice. In addition, it is important to bear in mind that the test should be evaluated in populations as similar as possible to those in which it will be applied in practice.

RESUMO

BACKGROUND: Rwanda is a sub-Saharan country, where intestinal parasite infections, anemia and undernutrition coexist. The purpose of this research is to study the relationship between intestinal parasite infections and undernutrition/anemia to clarify the priorities of intervention in the rural area of Gakenke district in the Northern Province of Rwanda. MATERIALS AND METHODS: A total of 674 students from Nemba I School, participated in a cross-sectional study, in which their parasitological and nutritional status were analysed. Statistical analysis was performed by χ2 test, univariate analysis and Odds ratios (OR). RESULTS: A total of 95.3% of children presented intestinal parasitism, most of whom (94.5%) infected by protozoa and 36.1% infected by soil-transmitted helminths (STH), with Trichuris trichiura (27.3%) being the most prevalent. Multiple infections were found to be high (83.8%), with protozoa and STH co-infections in 30.6%. STH infections were mainly of low/moderate intensity. Neither infection nor STH infection of any intensity profile, was significantly related to anemia. In addition, STH infection, regardless of the intensity profile, was not associated with stunting, underweight or thinness. There was no difference between genders nor among ages in odds of anemia and nutritional status in STH-infected schoolchildren. CONCLUSION: Multiparasitism remains high among Rwandan schoolchildren and is likely to cause nutritional problems. This work emphasizes the importance of keeping up health programs to reduce the prevalence of infection.

RESUMO

OBJECTIVES: This study aimed to understand therapists' lived experiences of delivering mentalisation-based therapy (MBT), including their experiences of service user change. METHOD: One-to-one semi-structured interviews or focus groups were conducted with 14 MBT therapists and analysed using interpretative phenomenological analysis (IPA). RESULTS: Four superordinate themes were identified: (1) experiencing the challenges and complexities of being with service users during MBT; (2) being on a journey of discovery and change; (3) being an MBT therapist: a new way of working and developing a new therapeutic identity; and (4) being a therapist in the group: seeing it all come together. CONCLUSION: Our findings highlight the complexity, challenges and individualised experience of working therapeutically with service users with a diagnosis of BPD. The study provides a perspective of service use change that is enriched by idiosyncrasies within the therapeutic encounter. We conclude with a consideration of implications for MBT research and clinical practice.

RESUMO

(1) Background: There are no real-world data evaluating the incidence of false-positive results. We analyzed the clinical and analytical factors associated with the presence of false-positive results in PSA determinations in practice. (2) Methods: A prospective cohort study of patients with a PSA test was performed in clinical practice. We followed the patients by reviewing their medical records for 2 years or until the diagnosis of PCa was reached, whichever came first. (3) Results: False-positive PSA rate was 46.8% (95% CI 44.2-49.2%) and false-negative PSA rate was 2.8% (95% CI 2-3.5%). Patients aged 61-70 years and those over 70 years were more likely to have a false-positive result than those under 45 years (aOR 2.83, 95% CI 1.06-7.55, p = 0.038, and aOR 4.62, 95% CI 1.75-12.22, p = 0.002, respectively). Patients with urinary tract infection were more likely to have a false-positive result (aOR 8.42, 95% CI 2.42-29.34, p = 0.001). Patients with diabetes mellitus were less likely to have a false-positive result (aOR 0.63, 95% CI 0.41-0.98, p = 0.038); (4) Conclusions: This study has generated relevant information that could be very useful for shared decision making in clinical practice.

RESUMO

INTRODUCTION: The Diabetes Health Profile (DHP-18), structured in three dimensions (psychological distress (PD), barriers to activity (BA) and disinhibited eating (DE)), assesses the psychological and behavioural burden of living with type 2 diabetes. The objectives were to adapt the DHP-18 linguistically and culturally for use with patients with type 2 DM in Ecuador, and to evaluate its psychometric properties. METHODS: Participants were recruited using purposive sampling through patient clubs at primary health centres in Quito, Ecuador. The DHP-18 validation consisted in the linguistic validation made by two Ecuadorian doctors and eight patient interviews. And in the psychometric validation, where participants provided clinical and sociodemographic data and responded to the SF-12v2 health survey and the linguistically and culturally adapted version of the DHP-18. The original measurement model was evaluated with confirmatory factor analysis (CFA). Reliability was assessed through internal consistency using Cronbach's alpha and test-retest reproducibility by administering DHP-18 in a random subgroup of the participants two weeks after (n = 75) using intraclass correlation coefficient (ICC). Convergent validity was assessed by establishing previous hypotheses of the expected correlations with the SF12v2 using Spearman's coefficient. RESULTS: Firstly, the DHP-18 was linguistically and culturally adapted. Secondly, in the psychometric validation, we included 146 participants, 58.2% female, the mean age was 56.8 and 31% had diabetes complications. The CFA indicated a good fit to the original three factor model (χ2 (132) = 162.738, p < 0.001; CFI = 0.990; TLI = 0.989; SRMR = 0.086 and RMSEA = 0.040. The BA dimension showed the lowest standardized factorial loads (λ) (ranging from 0.21 to 0.77), while λ ranged from 0.57 to 0.89 and from 0.46 to 0.73, for the PD and DE dimensions respectively. Cronbach's alphas were 0.81, 0.63 and 0.74 and ICCs 0.70, 0.57 and 0.62 for PD, BA and DE, respectively. Regarding convergent validity, we observed weaker correlations than expected between DHP-18 dimensions and SF-12v2 dimensions (r > -0.40 in two of three hypotheses). CONCLUSIONS: The original three factor model showed good fit to the data. Although reliability parameters were adequate for PD and DE dimensions, the BA presented lower internal consistency and future analysis should verify the applicability and cultural equivalence of some of the items of this dimension to Ecuador.

RESUMO

Scientific societies have provided guidelines to reduce PSA-specific harms. We studied the potential non-compliance of PSA testing with current guidelines in general practice. A cross-sectional study of a random sample of 1291 patients with a PSA test was performed between January and April 2018 in primary health care. Patients with a previous prostate cancer diagnosis or those who were being followed-up for previous high PSA values were excluded. Two independent researchers classified whether each test was potentially non-compliant with recommendations. We estimated frequencies of potentially non-compliant PSA determinations and calculated prevalence ratios (PR) to assess their relationship with possible explanatory variables. A total of 66% (95% CI: 62-69%) of PSA requests in asymptomatic patients were potentially non-compliant with the current guideline. This was associated with having a previous diagnosis of neoplasm (PR adjusted by age and life expectancy: 1.18; 95% CI: 1.02-1.37) as well as being a current consumer of tobacco, alcohol, or other drugs (PR: 0.80; 95% CI: 0.67-0.97). Real world data shows that patients are still frequently exposed to overdiagnosis risk with a PSA potentially non-compliant with recommendations. Patients diagnosed with another neoplasm or non-consumers of toxic substances were more exposed, probably due to increased contact with doctors or health-seeking behaviour.

RESUMO

Cysticercosis is a parasitic infection caused by the metacestode larval stage (cysticercus) of Taenia solium. In humans, cysticercosis may infect the central nervous system and cause neurocysticercosis, which is responsible for over 50,000 deaths per year worldwide and is the major cause of preventable epilepsy cases, especially in low-income countries. Cysticercosis infection is endemic in many less developed countries where poor hygiene conditions and free-range pig management favor their transmission. A cross-sectional study was conducted in 680 children from a rural primary school in Gakenke district (Northern province of Rwanda). Stool samples were collected from participants and analyzed using the Kato-Katz method (KK), formol-ether concentration (FEC), and/or copro-antigen enzyme-linked immunosorbent assay (CoAg-ELISA) to detect taeniasis. Blood samples were collected and analyzed using enzyme-linked immunoelectrotransfer blot (EITB) and antigen enzyme-linked immunosorbent assay (Ag-ELISA) to detect human cysticercosis. The overall proportion of taeniasis positivity was 0.3% (2/680), and both cases were also confirmed by CoAg-ELISA. A total of 13.3% (76/572) of the children studied were positive to cysticercosis (T. solium-specific serum antibodies detected by EITB), of whom 38.0% (27/71) had viable cysticercus (T. solium antigens by Ag-ELISA). This study provides evidence of the highest cysticercosis prevalence reported in Rwanda in children to date. Systematic investigations into porcine and human cysticercosis as well as health education and hygiene measures for T. solium control are needed in Gakenke district.

RESUMO

Diabetes is a major public health problem, increasingly affecting low- and middle-income countries. The project CEAD (Contextualizing Evidence for Action in Diabetes in low-resource settings) aims to evaluate the implementation of comprehensive diabetes care in two low-resource settings in Ecuador and to stimulate context-led health systems innovations to improve diabetes care and reduce inequity. The mixed-methods approach includes a 24-month retrospective study to assess the current level of implementation of comprehensive diabetes care and participants will be followed up prospectively for two years to assess changes in healthcare and clinical outcomes from the outset of the research. We will include individuals diagnosed with type-2 diabetes aged over 18 years, who are accessing diabetes care in health facilities in the study districts. Varied stakeholders (patients and family members, community members, healthcare workers and decision-makers) will interpret the underlying causes of the observed weaknesses and propose solutions to strengthen diabetes-related healthcare in focus group discussions (FG). A second set of FG will analyze perceived improvements in healthcare based on prospective cohort findings and consider the success/failure of any context-led innovations occurring throughout the research. Our study will demonstrate how evidence can be contextualized to stimulate local innovations and overcome weaknesses of diabetes-related healthcare in low resource settings.

RESUMO

Background: Visceral leishmaniasis (VL) is one of the most important parasitic diseases in the world. The domestic dog is the main reservoir of zoonotic VL and a high prevalence of canine leishmaniasis (CanL) is associated with transmission of infection to humans. Here we describe the methodology used to obtain a rapid and representative sample of domestic dogs in the city of Posadas, Misiones, and compare the prevalence of Leishmania infection with a sample of shelter dogs. Methodology: We used the city land registry to make a random selection of homes and systematically recruited 349 domestic dogs from the selected properties. We also included all dogs from the main canine shelter within the city. Dogs were examined by two experienced veterinarians who recorded the presence of clinical signs common in CanL using a standardized protocol. We extracted a blood sample from each dog and performed four different serological tests to reveal the presence of anti-Leishmania antibodies. Results: After clinical examination, 145 domestic dogs (41.5%) and 63 (90%) shelter dogs had clinical signs compatible with CanL (p < 0.001). The seroprevalence among domestic dogs was 20.1% (95% CI 16.1-24.6) which was significantly lower than among the abandoned dogs (38.6%, 95% CI 27.7-50.6, p < 0.001). The spatial distribution of infected dogs was fairly homogenous throughout the city. Among domestic dogs, we observed a positive association between where the dog slept and presence of anti-Leishmania antibodies (p = 0.034). Of the seropositive domestic dogs 38 (54.4%) were asymptomatic. Conclusions: Our findings demonstrate how seroprevalence results can be highly influenced by sampling methodology. We demonstrate how the land registry can be used to estimate the prevalence of CanL in representative sample of domestic dogs in an urban setting, allowing decision makers to deepen their understanding the epidemiology of CanL in a timely and efficient manner for the development of plans to address both human and canine disease.

RESUMO

BACKGROUND: Given that most evidence-based recommendations for managing type 2 diabetes mellitus (T2DM) are generated in high-income settings, significant challenges for their implementation exist in Latin America and the Caribbean region (LAC), where the rates of T2DM and related mortality are increasing. The aim of this study is to identify the facilitators and barriers to successful management of T2DM in LAC, from the perspectives of patients, their families or caregivers, healthcare professionals, and/or other stakeholders. METHODS: We conducted a systematic review in MEDLINE, Web of Science, SciELO, and LILACS. We included studies of disease management, prevention of complications and risk factor management. We qualitatively synthesized the verbatim text referring to barriers and/or facilitators of diabetes management according to the Theoretical Domain Framework and described their relative frequencies. FINDINGS: We included 60 studies from 1,595 records identified. 54 studies (90%) identified factors related to the environmental context and resources, highlighting the importance of questions related to health care access or lack of resources in the health system, and the environmental context and living conditions of the patients. Issues related to "social influences" (40 studies) and "social/professional role and identity" (37 studies) were also frequently addressed, indicating the negative impact of lack of support from family and friends and clinicians' paternalistic attitude. 25 studies identified patients beliefs as important barriers, identifying issues such as a lack of patients' trust in the effectiveness of the medication and/or the doctor's advice, or preferences for alternative therapies. CONCLUSIONS: Successful diabetes management in LAC is highly dependent on factors that are beyond the control of the individual patients. Successful disease control will require emphasis on public policies to reinforce health care access and resources, the promotion of a patient-centred care approach, and health promoting infrastructures at environmental level.
