Survival Analysis of COPD Patients in a 13-Year Nationwide Cohort Study of the Brazilian National Health System.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has an appreciable socioeconomical impact in low- and middle-income countries, but most epidemiological data originate from high-income countries. For this reason, it is especially important to understand survival and factors associated with survival in COPD patients in these countries. OBJECTIVE: To assess survival of COPD patients in Brazil, to identify risk factors associated with overall survival, including treatment options funded by the Brazilian National Health System (SUS). METHODOLOGY: We built a retrospective cohort study of patients dispensed COPD treatment in SUS, from 2003 to 2015 using a National Database created from the record linkage of administrative databases. We further matched patients 1:1 based on sex, age and year of entry to assess the effect of the medicines on patient survival. We used the Kaplan-Meier method to estimate overall survival of patients, and Cox's model of proportional risks to assess risk factors. RESULT: Thirty seven thousand and nine hundred and thirty eight patients were included. Patient's survival rates at 1 and 10 years were 97.6% (CI 95% 97.4-97.8) and 83.1% (CI 95% 81.9-84.3), respectively. The multivariate analysis showed that male patients, over 65 years old and underweight had an increased risk of death. Therapeutic regimens containing a bronchodilator in a free dose along with a fixed-dose combination of corticosteroid and bronchodilator seem to be a protective factor when compared to other regimens. CONCLUSION: Our findings contribute to the knowledge of COPD patients' profile, survival rate and related risk factors, providing new evidence that supports the debate about pharmacological therapy and healthcare of these patients.

Quality of life in individuals initiating antiretroviral therapy: a cohort study.

OBJECTIVE: To assess longitudinally the change in quality of life in people living with HIV initiating antiretroviral therapy in three public reference services specialized in HIV care in Belo Horizonte, Brazil. METHODS: Prospective cohort study among people living with HIV, aged 18 years or older, and initiating antiretroviral therapy. We obtained sociodemographic, behavioral, clinical data related to pharmacological treatment and to the service by face-to-face interviews, and supplemented these data with information from clinical records and Information Systems of the Brazilian HIV/AIDS Program. We measured the quality of life using the WHOQOL-HIV bref instrument, with a minimum interval of six months between the baseline and the follow-up interviews. We used paired t-test to assess the mean change in quality of life between the two interviewsand evaluated factors associated with this outcome using multiple linear regression. RESULTS: The overall quality of life, as well as the physical, psychological, level of independence, environment and spiritual quality of life domains were statistically higher in people living with HIV using antiretroviral therapy at the end of the follow-up. Factors independently associated with the increase in quality of life were having religious belief and living with other people. Having signs or symptoms of anxiety and depression and the number of adverse drug reactions reported were predictors associated with worsening quality of life. CONCLUSIONS: These results show an improvement in the quality of life over time in people living with HIV on antiretroviral therapy. They also highlight the need to monitor and provide health care support, especially for individuals with signs and symptoms of anxiety and depression and that report adverse reactions to medicines at the beginning of treatment.

Prevalence of smoking and associated factors in people living with HIV undergoing treatment.

OBJECTIVE: To estimate the prevalence of smoking and evaluate the factors associated with this outcome in people living with HIV (PLHIV). METHODS: This is a cross-sectional study of a prospective concurrent cohort of 462 individuals initiating antiretroviral therapy at three HIV/AIDS specialized services in Belo Horizonte between 2015 and 2017. The following smoking status were used: current smoker (CS), former smoker (FS) and non-smoker (NS). Multinomial logistic regression was performed with NS as the reference category. RESULTS: Most participants were men (81.4%), young (up to 34 years old; 57.2%) and non-white (75.7%). Of the total number of individuals, 27.7% were CS, 22.9% FS, and 49.4% NS. Most smokers were light smokers (65.1%), consumed up to 10 cigarettes per day and had been smoking for more than 10 years (63.3%), starting on average at 17.2 years of age (SD = 5.1). In the multivariate analysis, higher chances of being CS were associated with: being female, having up to 9 years of schooling, current or prior use of alcohol and illicit drugs (marijuana, cocaine and crack) and presenting signs and/or symptoms of anxiety or depression. Higher chances of being FS were associated with having up to 9 years of schooling and current or prior use of alcohol and illicit drugs (marijuana and crack). CONCLUSIONS: The results show that smoking is highly prevalent among PLHIV, indicating the need for HIV specialized services to prioritize smoking cessation interventions. These interventions should consider the use of alcohol and illicit drugs and be targeted especially to young people, those with low schooling and with signs and/or symptoms of anxiety or depression.

Effectiveness of Maintenance Immunosuppression Therapies in a Matched-Pair Analysis Cohort of 16 Years of Renal Transplant in the Brazilian National Health System.

The maintenance of patients with renal transplant typically involves two or more drugs to prevent rejection and prolong graft survival. The calcineurin inhibitors (CNI) are the most commonly recommended medicines in combinations with others. While immunosuppressive treatment regimens are well established, there is insufficient long-term effectiveness data to help guide future management decisions. The study analyzes the effectiveness of treatment regimens containing CNI after renal transplantation during 16 years of follow-up with real-world data from the Brazilian National Health System (SUS). This was a retrospective study of 2318 SUS patients after renal transplantion. Patients were propensity score-matched (1:1) by sex, age, type and year of transplantation. Kaplan-Meier analysis was used to estimate the cumulative probabilities of survival. A Cox proportional hazard model was used to evaluate factors associated with progression to graft loss. Multivariable analysis, adjusted for diabetes mellitus and race/color, showed a greater risk of graft loss for patients using tacrolimus plus mycophenolate compared to patients treated with cyclosporine plus azathioprine. In conclusion, this Brazilian real-world study, with a long follow-up period using matched analysis for relevant clinical features and the representativeness of the sample, demonstrated improved long-term effectiveness for therapeutic regimens containing cyclosporine plus azathioprine. Consequently, we recommend that protocols and clinical guidelines for renal transplantation should consider the cyclosporine plus azathioprine regimen as a potential first line option, along with others.

Does switching from multiple to single-tablet regimen containing the same antiretroviral drugs improve adherence? A group-based trajectory modeling analysis.

Combination Antiretroviral Therapy (cART) in single-tablet regimens (STR) is a simplification strategy that can potentially improve medication adherence and clinical outcomes. We conducted a retrospective cohort study of 1206 patients using efavirenz, tenofovir and lamivudine in multiple-tablet regimen who switched to the STR containing the same active ingredients in a southeast metropolis in Brazil. We measured adherence using the proportion of days covered (PDC≥95%) and evaluated this outcome before and after the switch using paired non-parametric statistics. Additionally, we used group-based trajectory modeling to identify adherence patterns to cART for each period and evaluate the migration behavior of patients between the trajectory groups. We observed a 14% increase in the proportion of adherent patients after switching to STR and a 6.2% increase in the proportion of patients with CD4 count>500 cells/µl (p < 0.001), without changes in viral load outcomes. We identified four adherence trajectories in each period. Most patients (60%, n = 722) migrated towards a group with better adherence trajectory or remained in the trajectory group with the highest probability of adherence after the switch. Our findings suggest that the implementation of the STR had a positive impact on adherence and CD4 count. This may potentially improve virologic outcomes later on treatment.

RESUMO OBJETIVO Avaliar longitudinalmente a alteração da qualidade de vida em pessoas que vivem com HIV iniciando a terapia antirretroviral, atendidas em três serviços públicos de referência na assistência especializada ao HIV em Belo Horizonte. MÉTODOS Estudo de coorte prospectivo, com o acompanhamento de pessoas que vivem com HIV, com 18 anos de idade ou mais, e iniciando terapia antirretroviral. Dados sociodemográficos, comportamentais, clínicos, relacionados ao tratamento farmacológico e ao serviço foram obtidos por entrevistas, complementados com informações dos prontuários clínicos e dos sistemas de informação do Programa Brasileiro de HIV/AIDS. A qualidade de vida foi avaliada utilizando o instrumento WHOQOLHIV-bref, por meio de entrevista face a face, com intervalo mínimo de seis meses entre as entrevistas. A alteração média na qualidade de vida entre as duas entrevistas foi avaliada utilizando o teste t pareado. Os fatores associados foram avaliados por meio de regressão linear múltipla. RESULTADOS A qualidade de vida global, assim como a qualidade de vida nos domínios físico, psicológico, nível de independência, ambiente e espiritual foram estatisticamente melhores em pessoas que vivem com HIV usando terapia antirretroviral no final do tempo de acompanhamento. Fatores independentemente associados ao incremento na qualidade de vida foram possuir crença religiosa e morar com outras pessoas. Enquanto ter sinais ou sintomas de ansiedade e depressão e o número de reações adversas a medicamentos reportadas foram preditores associados à piora da qualidade de vida. CONCLUSÕES Os resultados evidenciam melhora na qualidade de vida em pessoas vivendo com HIV iniciando a terapia antirretroviral ao longo do tempo. Evidenciam ainda a necessidade de se acompanhar e prover cuidados de saúde, em especial para indivíduos com sinais e sintomas de ansiedade e depressão e que relatam reações adversas a medicamentos no início do tratamento.

RESUMEN OBJETIVO: Estimar a prevalência do tabagismo e avaliar os fatores a ele associados em pessoas vivendo com HIV (PVHIV). MÉTODOS: Trata-se de estudo transversal de uma coorte prospectiva concorrente com 462 indivíduos em início de terapia antirretroviral atendidos em três serviços de assistência especializada ao HIV/aids em Belo Horizonte entre 2015 e 2017. Os status de tabagismo utilizados foram: fumante atual (FA), ex-fumante (EF) e não fumante (NF). Realizou-se regressão logística multinomial, sendo NF a categoria de referência. RESULTADOS: A maioria dos participantes eram homens (81,4%), jovens (de até 34 anos; 57,2%) e não brancos (75,7%). Do total de indivíduos, 27,7% eram FA, 22,9% EF, e 49,4% NF. A maioria dos tabagistas eram fumantes leves (65,1%), consumiam até 10 cigarros por dia e fumavam havia mais de 10 anos (63,3%), tendo começado em média aos 17,2 anos de idade (DP = 5,1). Na análise multivariada, maiores chances de ser FA se associaram a: ser do sexo feminino, ter até 9 anos de escolaridade, usar ou já ter usado álcool e drogas ilícitas (maconha, cocaína e crack) e apresentar sinais e/ou sintomas de ansiedade ou depressão. Maiores chances de ser EF se associaram a ter até 9 anos de escolaridade e usar ou já ter usado álcool e drogas e ilícitas (maconha e crack). CONCLUSÕES: Os resultados mostram que o tabagismo é altamente prevalente entre PVHIV, indicando a necessidade de os serviços de assistência especializada em HIV priorizarem intervenções a fim de cessá-lo, com abordagem sobre o uso de álcool e drogas ilícitas, especialmente voltadas para pessoas jovens, com baixa escolaridade e com sinais e/ou sintomas de ansiedade ou depressão.

Which antiretroviral regimen is associated with higher adherence in Brazil? A comparison of single, multi, and dolutegravir-based regimens.

We evaluated adherence to highly active antiretroviral therapy (HAART) and its associated factors according to the type of regimen in patients initiating treatment in Belo Horizonte, Minas Gerais State, Brazil. We measured adherence using the eight items Morisky Therapeutic Adhesion Scale (MMAS-8) and compared the use of "backbone" tenofovir/lamivudine plus efavirenz one tablet once-daily (STR) or dolutegravir in multi-tablet once-daily (MTR-DTG), or other multi-tablet regimens (MTR-other). We conducted a multivariate logistic regression analysis to address factors associated with adherence. A total of 393 patients were included, 254 used STR, 106 MTR-DTG, and 33 MTR-other. The overall adhesion rate was 44.8% (95%CI: 39.4; 50.1), 50% for MTR-DTG, 43.3% for STR and 39.4% for MTR-other. Multivariate analysis showed a higher chance of adherence among patients using MTR-DTG, those who received and understood counseling about their treatment and with a higher quality of life. Prior use of illicit drugs in the lifetime was associated with poorer adherence. Overall adherence was low, highlighting the need for strategies focusing on counseling about medicines and substance use. Pill burden was not an issue for patients using MTR-DTG once-daily, who achieved better results.

Health-related quality of life among HIV-infected patients initiating treatment in Brazil in the single-tablet regimen era.

Health-related quality of life (HRQoL) is a multidimensional concept involving an individual's self-perception about how a disease or treatment impacts their daily life. In this study, we evaluated the HRQoL and factors associated with this outcome in 366 patients initiating combination Antiretroviral Therapy (cART) in Belo Horizonte, Brazil.We measured HRQoL using the EuroQoL-5D 3 level (EQ-5D) and the HIV instrument of the World Health Organization (WHOQOL-HIV BREF) and identified factors associated with HRQoL using multilevel linear regression. Participants had been on cART treatment a median of 65.5 days at the time the instruments were completed. The median HRQoL of patients on the single-tablet regimen containing efavirenz/ tenofovir/ lamivudine and the multi-tablet regimen containing dolutegravir and tenofovir/ lamivudine were high, with no significant difference between groups. Factors consistently associated with lower HRQoL were being single (unmarried), having a lower educational level, recent cigarette smoking, recent signs and symptoms of anxiety or depression, comorbid disease and the occurrence of adverse drug reactions. We observed high levels of HRQoL in cART-treated people and no differences between dolutegravir and efavirenz-based regimens. This study provides inputs to future economic analysis and identifies opportunities to increase the HRQoL of patients by targeting modifiable factors.

Resumo: Avaliamos a adesão à terapia antirretroviral (TARV) e fatores associados de acordo com o tipo de esquema em pacientes no início do tratamento em Belo Horizonte, Minas Gerais, Brasil. Mensuramos a adesão com a Escala de Adesão Terapêutica de Morisky, de oito itens (MMAS-8), e comparamos o uso de tenofovir/lamivudina com efavirenz, um comprimido uma vez ao dia (STR), ou dolutegravir em múltiplos comprimidos uma vez ao dia (MTR-DTG), com outros esquemas com múltiplos comprimidos ao dia (MTR-outros). Conduzimos uma análise de regressão logística multivariada para avaliar os fatores associados à adesão. Foram incluídos 393 pacientes: 254 em uso de STR, 106 MTR-DTG e 33 MTR-outros. A taxa global de adesão foi 44,8% (IC95%: 39,4; 50,1), sendo 50% para MTR-DTG, 43,3% para STR e 39,4% para MTR-outros. A análise multivariada mostrou chances maiores de adesão em pacientes em uso de MTR-DTG, pacientes que haviam recebido e compreendido o aconselhamento sobre o tratamento e pacientes com melhor qualidade de vida. Uso anterior de drogas ilícitas em qualquer período da vida está associada à pior adesão. A adesão global foi baixa, enfatizando a necessidade de estratégias focadas no aconselhamento sobre medicamentos e uso de drogas. A quantidade de comprimidos não foi um problema para pacientes em uso de MTR-DTG uma vez ao dia, os quais alcançaram melhores taxas de adesão.

Resumen: Evaluamos la adherencia a la terapia antirretroviral altamente activa (TARAA) y sus factores asociados, según el tipo de tratamiento en pacientes que comenzaron su tratamiento en Belo Horizonte, Minas Gerais, Brasil. La adherencia se mensuró por la Escala de Adhesión Terapéutica de Morisky, de ocho ítems (MMAS-8), y se comparó el uso del "eje" tenofovir/lamivudina, además de un comprimido de efavirenz una vez al día (STR) o dolutegravir con varios comprimidos una vez al día (MTR-DTG), u otros tratamientos con múltiples comprimidos (MTR-otros). Se realizó un análisis multivariado de regresión logística para evaluar los factores asociados a la adherencia. Se incluyeron un total de 393 pacientes, 254 usaron STR, 106 MTR-DTG, y 33 MTR-Otros. La tasa de adherencia general fue de un 44,8% (95%CI: 39,4; 50,1), 50% en el MTR-DTG, 43,3% en el STR y 39,4% en el MTR-otros. El análisis multivariado mostró una probabilidad más alta de adherencia entre pacientes usando MTR-DTG, quienes recibieron y comprendieron las orientaciones acerca de sus tratamientos y los que disfrutaban de una calidad mejor de vida. El consumo previo de drogas ilícitas a lo largo de la vida estuvo asociado con una adherencia más escasa. La adherencia general fue baja y resalta la necesidad de estrategias que se enfoquen en brindar orientación sobre el uso de la medicación y de sustancias. El número de comprimidos no fue un problema para los pacientes que tomaban MTR-DTG una vez al día, que obtuvieron mejores resultados.

Effectiveness of antiretroviral therapy in the single-tablet regimen era.

OBJECTIVE: To evaluate the effectiveness of antiretroviral therapy and the associated factors according to the type of regimen used: Single Tablet Regimen or Multiple Tablet Regimen. METHODS: Prospective cohort of 440 patients (male, 74.3%, median age, 36 years old) who initiated antiretroviral therapy between Jan/14 and Dec/15 at a referral service in Belo Horizonte. Efficacy was defined as viral suppression (viral load, VL < 50 copies/ml) and evaluated after six and twelve months of treatment. Sociodemographic, clinical and behavioral data were collected from clinical charts and from Information Systems. Multivariate analysis of overall effectiveness was performed by logistic regression. RESULTS: Most patients initiated Multiple Tablet Regimen antiretroviral therapy (n = 255, 58%). At six months, overall viral suppression was 74.6%, being higher among patients who used Single Tablet Regimen (80.6%, p = 0.04). At twelve months, 83.2% of patients reached viral suppression, with no difference between groups (p = 0.93). Factors independently associated with viral suppression at six and twelve months varied, being negatively associated with effectiveness: VL ≥ 100,000 copies/ml, symptoms of AIDS, longer interval time between diagnosis and initiation of antiretroviral therapy, antiretroviral switching, smoking or current illicit drugs usage (p < 0.05). Factors positively associated with viral suppression included adherence to antiretroviral therapy and category of risk/exposure of men who have sex with men (p < 0.05). Reaching viral suppression at six months was the main predictor of effectiveness at one year (OR = 8.96 and p < 0.01). CONCLUSIONS: Viral suppression was high and better results were achieved for patients who used Single Tablet Regimen regimens at six months. Clinical, behavioral, and antiretroviral therapy -related factors influence viral suppression and highlight the need for interventions to increase early diagnosis and initiation of antiretroviral therapy, patient's adherence, and to reduce illicit drugs and cigarette smoking in this population.

Prevalence of Entamoeba histolytica and other enteral parasitic diseases in the metropolitan region of Belo Horizonte, Brazil. A cross-sectional study.

BACKGROUND: Enteral parasitic diseases are a public health problem in nations with low economic development and in settings with poor sanitation. Amebiasis is the second most frequent form of parasitosis, with a high burden of disease. Knowledge of the prevalence of enteroparasitoses in a given region is useful for planning clinical decision-making. Thus, the aim of this study was to estimate the prevalence of enteral parasitic diseases, especially amebiasis, through analysis on stool samples from public and private laboratories in a metropolitan area in southeastern Brazil. DESIGN AND SETTING: Cross-sectional study conducted in the metropolitan region of Belo Horizonte, Brazil. METHODS: We evaluated 6,289 fecal samples from one private and one public laboratory. The samples were concentrated by means of spontaneous sedimentation, and those that were positive for Entamoeba histolytica or Entamoeba dispar in optical microscopy analyses were processed to obtain deoxyribonucleic acid, with subsequent identification through the polymerase chain reaction. RESULTS: Among the stool samples, 942 (15.0%) had parasitic infections; 73 (1.2%) of these were helminthic infections and 847 (13.5%) were protozoan infections, caused mainly by Escherichia coli (6.0%), Endolimax nana (5.2%) and Giardia lamblia (1.2%). Infections due to Entamoeba histolytica or Entamoeba dispar occurred in 36 samples (0.6%) and the polymerase chain reaction revealed five (13.9%) as Entamoeba histolytica. CONCLUSION: The prevalence of enteral parasitic diseases is high in the metropolitan region of Belo Horizonte, although amebiasis may not be a problem.

Costs in the Treatment of Schizophrenia in Adults Receiving Atypical Antipsychotics: An 11-Year Cohort in Brazil.

BACKGROUND: Schizophrenia is associated with significant economic burden. In Brazil, antipsychotic drugs and outpatient and hospital services are provided by the Brazilian National Health System (SUS) for patients with schizophrenia. However, few studies capture the cost of managing these patients within the Brazilian NHS. This is important to appraise different management approaches within universal healthcare systems. OBJECTIVE: Our objective was to use real-world data to describe the costs associated with the treatment of schizophrenia in adults receiving atypical antipsychotics in Brazil from 2000 to 2010. METHODS: We integrated three national databases for adult patients with schizophrenia receiving one or more atypical antipsychotics. We assessed only direct medical costs and the study was conducted from a public-payer perspective. A multivariate log-linear regression model was performed to evaluate associations between costs and clinical and demographic variables. RESULTS: We identified 174,310 patients with schizophrenia, with mean ± standard deviation (SD) annual costs of $US1811.92 ± 284.39 per patient. Atypical antipsychotics accounted for 79.7% of total costs, with a mean annual cost per patient of $US1578.74 ± 240.40. Mean annual costs per patient were $US2482.90 ± 302.92 for psychiatric hospitalization and $US862.96 ± 160.18 for outpatient psychiatric care. Olanzapine was used by 47.7% of patients and represented 62.8% of the total costs of atypical antipsychotics. Patients who used clozapine had the highest mean annual cost per patient for outpatient psychiatric care and psychiatric hospitalization. CONCLUSIONS: Atypical antipsychotics were responsible for the majority of the schizophrenia treatment costs, and psychiatric hospitalization costs were the highest mean annual cost per patient. Authorities should ensure efficient use of atypical antipsychotics and encourage outpatient psychiatric care over psychiatric hospitalization where possible.

Adverse reactions associated with first-line regimens in patient initiating antiretroviral therapy.

OBJECTIVE: To evaluate the prevalence of adverse drug reactions (ADR) and associated factors during the use of Highly Active Antiretroviral Therapy (HAART) in patients initiating treatment. METHODS: This is a cross-sectional analysis of a prospective study conducted in three public referral services specialized in HIV/AIDS care in Belo Horizonte, Brazil. Self-reported ADR and explanatory variables were obtained from face-to-face interview and from Information Systems. Associated factors with ADR were evaluated by logistic regression in SPSS software v.22. RESULTS: We included 399 patients, of which 85.5% reported at least one and 72.7% up to 5 ADRs after HAART initiation. Neurological reactions were the most frequent, with self-reported ADRs being distinct according to HAART regimen used. The global model showed higher chance of ADRs among females (OR = 3.52) and illicit drug users (OR = 2.28). Lower chance of ADRs was found for patients aged > 33 years (OR = 0.37), DTG/TDF/3TC users (OR = 0.41), and higher physical domain of quality of life (OR = 0.78). The model restricted to patients using the single-tablet regimen EFV/TDF/3TC showed lower ADRs among patients with CD4+ T lymphocyte count > 200 cells/mm3 (OR = 0.23) and higher independence domain of quality of life (OR = 0.74). The model restricted to DTG/TDF/3TC and to other regimens showed lower ADRs with higher physical domain of quality of life (OR = 0.74 and OR = 0.55, respectively). CONCLUSIONS: The prevalence of self-reported ADRs to first-line antiretroviral regimens was high and patients using DTG/TDF/3TC had a smaller number of ADRs. In addition to HAART regimen, sociodemographic, clinical, and quality of life characteristics were associated with ADRs.

Effectiveness of antiretroviral therapy in the single-tablet regimen era / Efetividade da terapia antirretroviral na era de medicamentos em dose fixa combinada

RESUMO OBJETIVO Avaliar a efetividade da terapia antirretroviral e fatores associados segundo o tipo de esquema utilizado: medicamento em dose fixa combinada ou múltiplos medicamentos e doses. MÉTODOS Coorte prospectiva não concorrente de 440 pacientes que iniciaram terapia antirretroviral entre janeiro de 2014 e dezembro de 2015 em Belo Horizonte, MG. A efetividade foi definida como supressão viral (carga viral [CV] < 50 cópias/ml) e avaliada após seis e 12 meses de tratamento. Dados sociodemográficos, clínicos e comportamentais foram coletados de prontuário clínico e de sistemas de informação. A análise múltipla da efetividade global foi realizada por regressão logística. RESULTADOS A maioria dos pacientes iniciou terapia antirretroviral com múltiplos medicamentos e doses (58%). Aos seis meses, a supressão viral global foi 74,6%, maior entre pacientes que utilizaram dose fixa combinada (80,6%; p = 0,04). Aos 12 meses, 83,2% dos pacientes atingiram supressão viral, sem diferença entre os grupos (p = 0,93). Fatores independentemente associados à supressão viral em seis e 12 meses variaram, e foram negativamente associados à efetividade: CV ≥ 100.000 cópias/ml, sintomas definidores de aids, maior intervalo de tempo entre diagnóstico e início da terapia antirretroviral, troca de antirretroviral e consumo de tabaco ou drogas ilícitas (p < 0,05). Fatores positivamente associados à supressão viral incluíram adesão à terapia antirretroviral e categoria de risco/exposição de homens que fazem sexo com homens (p < 0,05). Atingir supressão viral aos seis meses foi o principal preditor de efetividade em um ano (OR = 8,96; p < 0,01). CONCLUSÕES A supressão viral foi elevada e superior para pacientes que utilizaram esquemas de dose fixa combinada aos seis meses. Fatores clínicos, comportamentais e relacionados à terapia antirretroviral influenciaram a supressão viral e evidenciam a necessidade de intervenções para aumentar o diagnóstico, o início precoce e a adesão dos pacientes à terapia antirretroviral, bem como reduzir o uso de drogas ilícitas e tabaco nesta população.

Gender differences and psychotropic polypharmacy in psychiatric patients in Brazil: a cross-sectional analysis of the PESSOAS Project.

We aimed to estimate the prevalence and correlates of psychotropic polypharmacy in Brazilian psychiatric patients by gender. Sociodemographic, behavioral and clinical data were obtained through face-to-face interviews and medical charts of 2,475 patients. Psychotropic polypharmacy was defined as the use of two or more psychotropic drugs and occurred in 85.7% of men (95%CI: 83.6%-87.6%) and 84.9% of women (95%CI: 82.8%-86.8%; p > 0.05). The mean number of psychotropic drugs/patient was 2.98 ± 1.23 and most common combinations included antipsychotics. Multivariate analysis showed that for both genders, previous hospitalization, severe mental illness, multiple psychiatric diagnoses and an insufficient number of professionals in the health care unit was associated with psychotropic polypharmacy. However, other correlates such as inpatient care, use of non-psychotropic drugs, living in unstable conditions and current smoking vary among them. Psychotropic polypharmacy was a common practice in this national sample. The results highlighted the need for national guidelines to manage patients with mental illness, considering the difference among genders and disease severity, to reduce the burden of polyphamacy in this population.

Resumo: Os autores tiveram como objetivo estimar a prevalência da polifarmácia psicotrópica e fatores associados entre pacientes psiquiátricos brasileiros, segundo o gênero. Foram obtidos dados sociodemográficos, comportamentais e clínicos por meio de entrevistas presenciais e prontuários médicos de 2.475 pacientes. A polifarmácia psicotrópica foi definida como o uso de dois ou mais medicamentos psicotrópicos, e foi constatada em 85,7% dos homens (IC95%: 83,6%-87,6%) e 84,9% das mulheres (IC95%: 82,8%-86, 8%; p > 0,05). A média de medicamentos psicotrópicos por paciente foi 2,98 ± 1,23, e as combinações mais comuns incluíam os antipsicóticos. A análise multivariada mostrou que, para ambos os gêneros, internação hospitalar prévia, doença psiquiátrica grave, múltiplos diagnósticos psiquiátricos e número insuficiente de profissionais na unidade de saúde foram associados à polifarmácia psicotrópica. Entretanto, fatores como cuidados hospitalares, uso de drogas não-psicotrópicas, condições de vida instáveis e tabagismo atual variaram de acordo com o gênero. A polifarmácia psicotrópica foi uma prática comum nessa amostra nacional. Os resultados evidenciam a necessidade de diretrizes nacionais para o manejo de pacientes com transtornos mentais, considerando a diferença entre gêneros e a gravidade da doença, para reduzir a carga da polifarmácia nessa população de pacientes.

Resumen: El objetivo de los autores fue estimar la prevalencia de la polifarmacia psicotrópica y factores asociados entre pacientes psiquiátricos brasileños, según con el género. Se obtuvieron datos sociodemográficos, comportamentales y clínicos, a través de entrevistas presenciales y registros médicos de 2.475 pacientes. La polifarmacia psicotrópica se definió como el uso de dos o más medicamentos psicotrópicos, y fue constatada en un 85,7% de los hombres (IC95%: 83,6%-87,6%) y en un 84,9% de las mujeres (IC95%: 82,8%-86,8%; p > 0,05). La media de medicamentos psicotrópicos por paciente fue de 2,98 ± 1,23, y las combinaciones más comunes incluían los antipsicóticos. El análisis multivariado mostró que, para ambos géneros, el internamiento hospitalario previo, enfermedad psiquiátrica grave, múltiples diagnósticos psiquiátricos, y número insuficiente de profesionales en la unidad de salud, estuvieron asociados a la polifarmacia psicotrópica. Asimismo, otros correlatos, tales como cuidados hospitalarios, uso de medicamentos no-psicotrópicos, condiciones de vida inestables y tabaquismo actual variaron de acuerdo con el género. La polifarmacia psicotrópica fue una práctica común en esa muestra nacional. Los resultados destacan la necesidad de directrices nacionales para cuidar de pacientes con trastornos mentales, considerando la diferencia entre géneros y la gravedad de la enfermedad, para reducir la carga de la polifarmacia en esa población de pacientes.

Assessment of the scope of practice of physicians participating in the Mais Médicos (More Doctors) Program, and associated factors. / Avaliação do escopo de prática de médicos participantes do Programa Mais Médicos e fatores associados.

The purpose of this study was to characterize the scope of practice of physicians working in primary healthcare participating in the Mais Médicos (More Doctors) Program ('PMM') and investigate the factors associated with execution of a larger number of clinical activities. It is an exploratory study carried over January to March 2016, through a self-applied questionnaire containing a list of 49 procedures, activities and actions carried out in primary healthcare. A total of 1,241 physicians took part in the study, most of them female, between age 40 and 49, and of Cuban nationality. The physicians carried out an average of 22.8 ± 8.2 procedures; they reported knowing how to carry out a larger number of procedures. Factors associated with executing a larger number of procedures were: being male, having graduated more recently, two years or less practicing in their primary healthcare unit, practicing in the North or South geographical regions, in small towns and more distant from the regional health headquarters. The main reason for not carrying out the procedures and activities that they reported knowing how to do was the lack of materials and inadequate infrastructure. The results show that the scope of practice of the physicians of the PMM is lower than their capacities, and that interventions with the intention of widening their scope are necessary.

Avaliação do escopo de prática de médicos participantes do Programa Mais Médicos e fatores associados / Assessment of the scope of practice of physicians participating in the Mais Médicos (More Doctors) Program, and associated factors

Resumo O objetivo deste estudo foi caracterizar o escopo de prática de médicos inseridos na Atenção Primária em Saúde (APS), participantes do Programa Mais Médicos (PMM) e investigar os fatores associados à execução de maior número de atividades clínicas. Trata-se de um estudo exploratório transversal realizado entre janeiro e março de 2016, por meio de questionário autoaplicável, contendo uma lista de 49 procedimentos, atividades e ações realizadas na APS. Participaram do estudo 1.241 médicos, a maioria do sexo feminino, entre 40-49 anos de idade, de nacionalidade cubana. Os médicos realizaram uma média de 22,8 ± 8,2 procedimentos, porém, relataram saber fazer um número maior. Fatores associados à realização de maior número de procedimentos foram sexo masculino, menor tempo de graduação, dois anos ou menos de atuação na UBS, atuar na região geográfica Norte ou Sul, em municípios de pequeno porte e mais distantes da sede da região de saúde. O principal motivo para não realizar os procedimentos e atividades que relataram saber fazer foi a falta de materiais e a infraestrutura inadequada. Os resultados revelam que o escopo de prática dos médicos do PMM está abaixo de suas capacidades, sendo necessárias intervenções para o ampliar.

Non-prescription sale and dispensing of antibiotics in community pharmacies in Zambia.

BACKGROUND: In Zambia, antibiotics are categorized as prescription-only medicines. Antibiotics dispensed without a prescription pose a public health threat, which is a concern. Consequently, the aim is to ascertain the extent of non-prescription sales and dispensing of antibiotics in community pharmacies in Zambia. METHODS: The practice of non-prescription sale and dispensing were assessed in 73 randomly selected community retail pharmacies, using a structured interviewer-administered questionnaire with simulated case scenarios. RESULTS: Majority (97%) stated that clients frequently requested non-prescribed antibiotics. Interviewees usually asked clients' indications (94%), counselled on dosing (96%) and suggested changes to antibiotic choices (97%). All (100%) dispensed non-prescribed antibiotics. Commonly dispensed antibiotics included amoxicillin (52%), cotrimoxazole (25%) and metronidazole (23%). Non-prescription sale and dispensing of antibiotics was significantly associated with interviewees' professional qualification in four out of five simulations. CONCLUSION: Non-prescription sale and dispensing of antibiotics is widespread in Zambia. Concerted public and professional interventions are needed coupled with stronger regulatory enforcement to reduce this.
