Mortality and years of life lost related to adverse drug events in Brazil

OBJECTIVE

To assess regional and national mortality and years of life lost (YLL) related to adverse drug events in Brazil.

METHODS

This is an ecological study in which death records from 2009 to 2018 from the Mortality Information System were analyzed. Codes from the International Classification of Diseases 10th revision (ICD-10) that indicated drugs as the cause of death were identified. The number of deaths and the YLL due to adverse drug events were obtained. Crude, age- and gender-specific, and age-adjusted mortality rates and YLL rates per 100,000 inhabitants were formed by year, age group, gender, and Brazilian Federative Unit. Rate ratios were calculated by comparing rates from 2009 to 2018. A joinpoint regression model was applied for temporal analysis.

RESULTS

For the selected ICD-10 codes, a total of 95,231 deaths and 2,843,413 YLL were recorded. Mortality rates from adverse drug events increased by a mean of 2.5% per year, and YLL rates increased by 3.7%. Increases in rates were observed in almost all age groups for both genders. Variations in rates were found between Federative Units, with the highest age-adjusted mortality and YLL rates occurring in the Distrito Federal.

CONCLUSIONS

The numbers and rates of deaths and YLL increased during the study period, and variations in rates of deaths and YLL were observed between Brazilian Federative Units. Information on multiple causes of death from death certificates can be useful for quantifying adverse drug events and analyzing them geographically, by age and by gender.

Concordance analysis of two databases to search for potential drug interactions in onco-hematologic patients

INTRODUCTION

Potential drug interactions exert a significant impact on patient safety, especially within intricate onco-hematological treatments, potentially resulting in toxicity or treatment failures. Despite the availability of databases for potential drug interaction investigation, persistent heterogeneity in concordance rates and classifications exists. The additional variability in database agreement poses further complexity, notably in critical contexts like onco-hematology.

AIM

To analyze the concordance of two databases for researching potential drug interaction in prescriptions for hematological patients at a University Hospital in the Midwest region of Brazil.

METHOD

Cross-sectional study developed in a Brazilian hospital. The search for potential drug interaction was conducted in Micromedex® and UpToDate®. The variables were: the presence of potential drug interaction, severity, mechanism, management, and documentation. Data was analyzed in terms of frequency (absolute and relative), Cohen's kappa, and Fleiss kappa.

RESULTS

The presence of potential drug interaction, showed a lack of concordance between the databases (k = -0.115 [95% CI: 0.361-0.532], p = 0.003). Regarding the mechanism, a strong agreement was observed (k = 0.805, p < 0.001 [95% CI: 0.550-0.941]). The management concordance showed a fair agreement, 46.8% (k = 0.22, p < 0.001 [95% CI: 0.099-0.341]). Stratifying the categories, significant concordance was observed in "Adjustment of dose + Monitoring" (k = 0.302, p = 0.018) and "Monitoring" (k = 0.417, p = 0.001), while other categories did not reach statistical significance.

CONCLUSION

Our study emphasizes the variability in potential drug interaction research, revealing disparities in severity classification, management recommendations, and documentation practices across databases.

Hospitalizations and adverse drug events in the Brazilian unified health system: a ten-year retrospective analysis of routine data

OBJECTIVE

To describe the frequency and characteristics of hospitalizations for/with adverse drug events in the Brazilian unified health system routine data.

METHODS

Nationwide retrospective study using data obtained from a period of ten years from the Brazil Hospital Information System (SIH-SUS), an administrative database that registers hospitalizations in the unified health system. We selected hospitalizations with primary and/or secondary diagnosis related to adverse drug events according to a list of validated International Classification Disease 10th edition (ICD-10) codes. These events were described according to year, age group, sex, length of hospital stay, mortality, hospital costs, Brazilian geographical region, and category of ICD-10 codes. Crude hospitalization rates of adverse drug events per 100,000 inhabitants were obtained and Joinpoint Regression was used to analyze temporal changes in these rates along the years. The most frequent ICD-10 codes were also identified.

RESULTS

Over ten years, 603,663 hospitalizations in Brazil were found in the database, out of which 2.5% of the patients died. Though 2009 had the highest prevalence of hospitalization per 100,000 inhabitants (32.57), no significant annual change in rates was found for the entire period. All age groups and sexes presented a jointpoint in temporal series; however, only women had a significative increase trend. The most frequent codes were from the chapter of mental and behavioral disorders (F19.2, F19.0, and F19.5 codes).

CONCLUSIONS

The database methodology can be useful to estimate frequencies of adverse drug events and perform characterization nationwide and to help monitor morbidity along the years.

"A lack of information keeps us from medicine, well-being, harmony…": a mixed method study with plaintiffs requesting medicines in administrative cases

The need to request public health managers to ensure the right of access to medicines characterizes an administrative case and the method to do so is called the administrative route. This mixed method study aimed to analyze the perceptions of plaintiffs requesting medications by the administrative route about barriers to access medicines in the Brazilian public health sector. Data were gathered through focus groups and questionnaires. The results point to the interdependence of pharmaceutical services with the interfacing areas to ensure access. The barriers related to individuals reflect the commitment to develop citizenship, justifying the cost of the medicine to motivate the demand. Barriers to service provision include irregular availability of medicines, insufficient resources, and unsatisfactory quality of services. The difficulty in obtaining medical consultations and prescriptions originating in the public sector are barriers to the health sector. The barriers above the health sector are compliance with administrative procedures, corruption, and clientelism. The administrative route intensifies inequities in access to healthcare in Brazil.

Hospitalizations and deaths related to adverse drug events worldwide: Systematic review of studies with national coverage

PURPOSE

Adverse drug events are related to negative outcomes in healthcare, including hospitalization, increased duration of hospital stay and death. The aim of this study was to conduct a systematic review to evaluate hospitalizations and deaths related to adverse drug events worldwide, reported in studies with national coverage.

METHODS

The protocol was registered in PROSPERO (CRD42020157008). We performed a systematic search on Medline, Embase, CINAHL, LILACS, and the Cochrane Library (until March 2020) using pre-specified terms. We included published studies that reported data on hospitalizations and/or deaths related to adverse drug events from a national perspective and the use of secondary data as a source of information. Two reviewers independently extracted and synthesized data. The quality of the studies was assessed using an adapted version of the Joanna Briggs Institute critical appraisal checklist for prevalence studies. Narrative summaries of findings were undertaken.

RESULTS

Among 59,336 citations, 62 studies were included for data extraction and synthesis. Among these studies, 41 studies included the outcome of hospitalization, 16 included the death outcome, and five included both outcomes. Administrative databases regarding discharges and registries of vital statistics were the most common sources of information. The relative frequency of hospitalizations ranged from 0.03% to 7.3%, and from 9.7 to 383.0/100,000 population, whereas mortality rate ranged from 0.1 to 7.88/100,000 population.

CONCLUSION

Our study highlights information about adverse drug events using large administrative databases in a national scenario and provides an overview of databases and methods implemented to detect adverse drug events.

Institutional strategies as a mechanism to rationalize the negative effects of the judicialization of access to medicine in Brazil

Background

Recently, the Executive Branch and Judiciary in Brazil increased spending due to larger numbers of lawsuits that forced the State to provide health goods and services. This phenomenon, known as health judicialization, has created challenges and required the Executive Branch and Judiciary to create institutional strategies such as technical chambers and departments to reduce the social, economic and political distortions caused by this phenomenon. This study aims to evaluate the effects of two institutional strategies deployed by a Brazilian municipality in order to cope with the economic, social and political distortions caused by the phenomenon of health judicialization regarding access to medicines.

Methods

A longitudinal study was carried out in a capital in the Central-West Region of Brazil. A sample of 511 lawsuits was analyzed. The variables were placed into three groups: the sociodemographic characteristics and the plaintiffs’ disease, the characteristics of the claimed medical products and the institutional strategies. To analyze the effect of the interventions on the total cost of the medicines in the lawsuits, bivariate and multivariate linear regressions with variance were performed. For the categorical outcomes, Poisson regressions were performed with robust variance, using a significance level of 5%.

Results

A reduction in the costs of medicines in the lawsuits and of the requests for medicines within the SUS formulary was verified after the deployment of the Department of Assessment of Nonstandardized Medicines (DAMNP) and the Technical Chamber of Health Assessment (CATS); an increase in processed prescriptions from the Brazilian Universal Health System was observed after the deployment of the CATS; and an increase in medicines outside the SUS formulary without a therapeutic alternative was verified after the CATS.

Conclusion

The institutional strategies deployed were important tools to reduce the high costs of the medicines in the lawsuits. In addition, they represented a step forward for the State, provided a benefit to society and indicated a potential path for the health and justice systems of other countries that also face problems caused by the judicialization of health.

Evaluation of a method for drug-related problems identification and classification in hospital setting: applicability and reliability

Background Prescription evaluation by pharmacists has potential to improve pharmacotherapy management. It requires the use of robust methods to identify drug-related problems (DRP), which are important issues in pharmacotherapy. Objective To evaluate the applicability and reliability of Grupo de Investigação em Cuidados Farmacêuticos (GIGUF) method for prescription analysis, identification and classification of drug-related problems in inpatients prescriptions. Setting Department of Medical Clinic of a tertiary and teaching Brazilian hospital. Method An observational and retrospective study of identification and classification of drug-related problems. GIGUF method was used to evaluate prescriptions of hematological patients hospitalized between August and October 2015. The problems were categorized using GICUF-method classification. Three pharmacists performed inter-rater agreement analysis of the method using Kappa. Differences in prevalence of DRP was calculated by age, sex, pharmacotherapy complexity, length of stay and number of drugs. Main outcome measure (a) frequency and characteristics and (b) inter-rater agreement in identification and classification of the drug-related problems. Results A total of 211 problems were identified and 'inadequate dosing' was the most common problem. There was an association between the occurence of a drug-reklated problem and complexity of pharmacotherapy (p = 0.001) and number of drugs used (p = 0.010). The overall inter-rater agreement was moderate (k = 0.44 IC 95% 0.34-0.55) and the problem 'not suitable drug' (k = 0.55 IC 95% 0.44-0.66) had greater inter-rater agreement. Conclusion The method "Evaluation Drug Use Process" was useful for prescription analysis since it made the identification and classification of DRPs possible. The method demonstrated a moderate inter-rater agreement, and can contribute to pharmacotherapy management by hospital pharmacists.

Performance of Laboratories after 10 Years of Participating in External Quality Monitoring in Cervical Cytology

OBJECTIVE

To evaluate the performance of laboratories accredited by the National Health System that perform cytopathology examination of the uterine cervix after 10 years of participation in external quality monitoring (eQM).

STUDY DESIGN

Seven laboratories were assessed in this study. To assess the concordance of the representation of epithelia and results, 6,536 examinations (3,433 in 2007 and 3,103 in 2017) were reviewed. Statistical analysis was performed using the κ coefficient as well as the χ2 and the Fisher exact test (p < 0.05).

RESULTS

All laboratories showed adequate infrastructure and internal quality monitoring. Regarding the representation of the epithelia, the concordance remained excellent (κ between 0.84 and 0.94). In 2007, 26 false-negative results (FN), 157 false-positive results (FP), and 79 delays in clinical conduct (DCC) were identified (κ = 0.80). In 2017, 24 FN, 42 FP, and 38 DCC were identified (κ = 0.90). Five laboratories showed improvement in concordance from 2007 to 2017. We observed significant improvement in cytomorphological criteria of the results: atypical squamous cells of undetermined significance (p < 0.001), atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (p < 0.016), and low-grade squamous intraepithelial lesion (p < 0.001). We also observed a considerable improvement in the results of cellular abnormalities in glandular epithelium (p < 0.0504).

CONCLUSIONS

Ten years after the implementation of eQM, improvements in the concordance of results were observed as well as reductions in FN, FP, and DCC in all laboratories monitored.

Administrative cases: an effective alternative to lawsuits in assuring access to medicines?

BACKGROUND

Although public policy in Brazil supports access to essential medicines, the health system cannot meet all demand. Increasingly, the population has used legal demands to seek access to medicines, an approach that can undermine equitable access by creating policy inconsistencies (e.g., granting access to medicines outside the SUS formulary). In response, the Executive Branch has signed institutional agreements to create an administrative case for submitting requests for medicines directly to the Executive Branch. The objective of this study was to assess the degree to which the administrative cases for requests are in accordance with public policies and guidelines, e.g., if administrative cases results in fewer decisions to purchase outside the SUS formulary.

METHODS

This descriptive study used secondary data from lawsuits filed against the Executive Branch from 2003 to 2015 and from administrative cases granted by the Executive Branch from 2010 to 2015 in the capital of a state located in the central-western region of Brazil. The variables included plaintiffs' sociodemographic characteristics and diseases as well as the characteristics of the medical products sought via the processes.

RESULTS

Comparing the requests submitted through lawsuits and the administrative cases revealed differences in the incomes of plaintiffs and the costs of medicines. Both methods for submission recorded requests for medicines for diseases of endocrine and circulatory systems; the only difference was the prevalence of diseases of the genitourinary system in the lawsuits. A higher proportion of lawsuits sought medicines outside the SUS formulary with therapeutic alternatives, while medicines outside the SUS formulary without an alternative were more commonly requested in administrative cases.

CONCLUSION

Administrative cases adhere to the public policies and guidelines of the SUS. The administrative cases results in fewer decisions to purchase outside the SUS formulary with alternative, and more decisions to purchase drugs for which there is a formulary alternative. In addition, administrative cases provide greater equity by favoring lower income applicants. However, administrative cases also reveal deficiencies in the State's implementation of existing pharmaceutical policies. The public pressure for effective implementation of existing policies may help expand access to medicines.

Performance of rapid prescreening and 100% rapid review as internal quality control methods for cervical cytopathology

BACKGROUND

An objective of quality control for cervical cytopathology is reducing high rates of false-negative results of laboratory tests. Therefore, methods to review smears such as rapid prescreening and 100% rapid review, which have shown better performance detecting false-negative results, have been widely used. The performance of rapid prescreening and the performance of 100% rapid review as internal quality control methods for cervical cytology examinations were evaluated.

METHODS

For 24 months, 9318 conventional cervical cytology smears underwent rapid prescreening and routine screening. The 100% rapid review method was performed for 8244 smears classified as negative during routine screening. Any discordant results underwent detailed review to define the final diagnosis. This was considered the gold standard for evaluating the performance of rapid prescreening and 100% rapid review.

RESULTS

Routine screening showed increases of 13.3% and 11.5% in the detection of abnormal smears with rapid prescreening and 100% rapid review, respectively. The relative percentage variation showed a 38.1% increase in the diagnosis of atypical squamous cells of undetermined significance with routine screening and rapid prescreening and a 12.5% increase in the diagnosis of atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion with both rapid prescreening and 100% rapid review. Sensitivity rates of rapid prescreening and routine screening were 48.2% and 83.2%, respectively. Sensitivity rates of rapid prescreening and 100% rapid review were 65.7% and 57.8%, respectively, for detecting false-negative results.

CONCLUSIONS

Inclusion of rapid prescreening and/or 100% rapid review improved the diagnostic sensitivity of the cervical cytology examination and reduced false-negative results of routine screening and can provide good quality control.

Impact of Implementing 100% Rapid Review as a Quality Control Tool in Cervical Cytology

OBJECTIVE

We aimed to evaluate the impact of implementing 100% rapid review (100% RR) as a quality control tool in cervical smear cytology.

DESIGN

A cross-sectional study was conducted in which cytology findings, false-negative results, and quality indicators were evaluated. The variables were analyzed in 2004, the year in which 100% RR was implemented, and again in 2013, i.e., 10 years on.

RESULTS

Detection of atypical squamous cells of undetermined significance (ASC-US) increased from 0.90% in 2004 to 2.47% in 2013 by routine screening. Detection of atypical squamous cells, cannot exclude a high-grade squamous intraepithelial lesion (ASC-H) increased from 13.33% in 2004 to 36.27% in 2013 by 100% RR. Detection of high-grade squamous intraepithelial lesion (HSIL) increased from 0.64% in 2004 to 4.29% in 2013 by routine screening, and increased from 0% in 2004 to 19.61% in 2013 by 100% RR. There was a significant increase (p = 0.00001) in the identification of false-negative results of ASC-US, low-grade squamous intraepithelial lesion, ASC-H, HSIL, and atypical glandular cells. All quality indicators had increased in 2013 when compared to 2004 results.

CONCLUSIONS

Ten years after the implementation of the 100% RR method, improvements were found in the detection of atypia and precursor lesions and in quality indicators.

Medication dispensing as an opportunity for patient counseling and approach to drug-related problems

ABSTRACT The objective was to describe and evaluate a model of drug dispensing developed and implemented in a community pharmacy in Brazil. This was a descriptive, observational, quasi-experimental study performed in the period between 21 January 2013 and 20 April 2013. The model was evaluated and described in terms of three parameters: structure, process and outcome. The description and assessment of each parameter was performed as follows: (I) Structure: profile of patients, pharmacist's professional profile, physical facility, informational material; (II) Process: drug-related problems, pharmaceutical interventions performed, results of pharmaceutical interventions; (III) Outcome: patient knowledge of medications. Dispensing service improved patient knowledge of medications (p < 0.05), which was associated with pharmacotherapy complexity (p < 0.05). The main problems identified were related to lack of patient knowledge regarding their medication (52.9%). Pharmaceutical interventions were mostly performed directly to the patients (86.3%) by verbal (95.4%) and written (68.2%) information, and most of the problems were completely solved (62.7%). The medicine dispensing model was able to identify and solve drug-related problems and promote an improvement in patient knowledge about medication.

Quality Indicators of Cervical Cytopathology Tests in the Public Service in Minas Gerais, Brazil

OBJECTIVE

The objective of this study is to assess the performance of cytopathology laboratories providing services to the Brazilian Unified Health System (Sistema Único de Saúde - SUS) in the State of Minas Gerais, Brazil.

METHODS

This descriptive study uses data obtained from the Cervical Cancer Information System from January to December 2012. Three quality indicators were analyzed to assess the quality of cervical cytopathology tests: positivity index, percentage of atypical squamous cells (ASCs) in abnormal tests, and percentage of tests compatible with high-grade squamous intraepithelial lesions (HSILs). Laboratories were classified according to their production scale in tests per year ≤ 5,000; from 5,001 to 10,000; from 10,001 to 15,000; and ≥ 15,001. Based on the collection of variables and the classification of laboratories according to production scale, we created and analyzed a database using Microsoft Office Excel 97-2003.

RESULTS

In the Brazilian state of Minas Gerais, 146 laboratories provided services to the SUS in 2012 by performing a total of 1,277,018 cervical cytopathology tests. Half of these laboratories had production scales ≤ 5,000 tests/year and accounted for 13.1% of all tests performed in the entire state; in turn, 13.7% of these laboratories presented production scales of > 15,001 tests/year and accounted for 49.2% of the total of tests performed in the entire state. The positivity indexes of most laboratories providing services to the SUS in 2012, regardless of production scale, were below or well below recommended limits. Of the 20 laboratories that performed more than 15,001 tests per year, only three presented percentages of tests compatible with HSILs above the lower limit recommended by the Brazilian Ministry of Health.

CONCLUSION

The majority of laboratories providing services to the SUS in Minas Gerais presented quality indicators outside the range recommended by the Brazilian Ministry of Health.

Medication adherence in patients in treatment for rheumatoid arthritis and systemic lupus erythematosus in a university hospital in Brazil

Medication adherence is essential for the control of symptoms and progression of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). The aim of the study was to investigate medication adherence in outpatients in treatment for RA and SLE in a university hospital in Brazil. This was a quantitative, cross-sectional analytical study. A total of 92 patients (55 RA patients and 37 SLE patients) were included in the study. A structured questionnaire for patients' interview and a form for collecting data from medical records were used for data collection. Adherence to drug treatment was assessed by the Morisky scale questionnaire. Data storage and analysis were performed using Epi Info 3.5.4 and statistical analysis by Stata/SE 12.0. The Pearson's chi-squared test and Fisher's exact test were applied for statistical and bivariate analyses. For multivariate data analysis the Poisson regression and the Wald test were used. The prevalence of adherence to drug treatment was 16.4% in RA patients and 45.9% in SLE patients. The final model of the multivariate analysis demonstrated associations between medication adherence and the following covariates for both RA and SLE groups: duration of therapy for rheumatic disease at the institution greater than 15 years and presence of more than six chronic comorbidities. The parameter "acquisition of medication at the high-cost pharmacy" was differently associated with medication adherence by group, and for the SLE group, living outside the city of Goiânia was a protective factor associated with adherence. This study demonstrated a low prevalence of medication adherence in patients in treatment for RA and SLE treated at this institution. These findings will serve as a base for future studies to elucidate what factors may positively or negatively affect medication adherence in this population. In addition, multidisciplinary approaches are needed to enhance adherence to drug treatment in patients in treatment for rheumatic disease.

Conclusão: A maioria dos laboratórios que apresentaram indicadores dentro dos parâmetros recomendados participa do monitoramento externo da qualidade.

Internal quality control for cervical cytopathology: comparison of potential false-negatives detected at rapid prescreening and at 100% rapid review

OBJECTIVE

To evaluate the performance of rapid prescreening (RPS) and 100% rapid review (RR-100%) as internal quality control (IQC) methods assessed by outcome at colposcopy, histopathology and repeat cytopathology for cases with false-negative results on cervical cytopathology at routine screening (RS).

STUDY DESIGN

Out of 12,208 cytology smears analyzed, 900 were abnormal. Of these, 656 were identified at RS, and 244 were false-negative, with 90.2% identified at RPS and 57.4% at RR-100%. Of the 900 abnormal cases, 436 were submitted for additional testing.

RESULTS

Of the 244 women with cytopathological abnormalities identified only by the IQC methods, 114 had supplementary examinations: 35 were submitted for colposcopy, 22 for biopsy and 99 for repeat cytopathology. The sensitivity of RPS for the detection of abnormalities identified on colposcopy, histopathology and repeat cytopathology was 87.5% (95% CI 67.6-97.3), 82.4% (95% CI 56.6-96.2) and 95.7% (95% CI 85.2-99.5), respectively. The sensitivity of RR-100% was 54.2% (95% CI 32.8-74.4), 52.9% (95% CI 27.8-77.0) and 47.8% (95% CI 32.9-63.1), respectively. RPS was more sensitive than RR-100% when compared to the findings on colposcopy (p = 0.011) and repeat cytopathology (p = 0.000). When compared to colposcopy, histopathology and repeat cytopathology, the sensitivity of RS was 83.2% (95% CI 76.1-88.9), 85.7% (95% CI 78.1-91.5) and 73.3% (95% CI 66.0-79.7), respectively.

CONCLUSION

RPS performed better than RR-100% when compared to the results of colposcopy and repeat cytopathology.

[Impact of training about cervical cancer screening on health professionals working in basic health care units]

PURPOSE

To evaluate the impact of training professionals involved in the screening for cervical cancer in Basic Health Units in the city of Goiânia (GO).

METHODS

This was and intervention study in which the following data contained in the cervical cytopathology test form were examined: the woman's personal data, anamnesis, clinical examination and identification of the professional responsible for the collection. Professional training was evaluated by comparing the forms referring to the period from January 2007 to April 2009, before training, with the forms referring to the period from July 2010 to December 2012, after training. The Pearson χ2 test was used to analyze the results of training, with the 5% level of significance.

RESULTS

After training, there was a significantly increased frequency of recording patient schooling (from 67.2 to 92.6%, p<0.001), telephone number (from 78.9 to 98.7%, p<0.001), cervical inspection (from 86.8 to 96.6%, p<0.001), and signs suggestive of sexually transmitted diseases (from 80.8 to 93.5%, p<0.001). There was a reduction in the frequency of performing the exam within an interval of less than one year (p<0.001) and of one year (p<0.001). There was a reduction in the frequency of Pap smear testing in women under 25 years of age, from 22.0 to 17.9% (p<0.001). There was a significant increase in the proportion of satisfactory samples from 70.4 to 80.2% (p<0.001). A reduction of confounding factors was observed. The desiccation frequency was 2.9% before training and 2.0% after training (p<0.001). There was an increase in the frequency of representation of endocervical cells from 79.5 to 88.5% (p<0.001).

CONCLUSION

After training, there was a significant improvement in completing the application form, the performance of such tests regarding frequency and the age range recommended by the Ministry of Health, and the adequacy of the sample.

Das 24 mulheres com resultado citopatológico classificado como células glandulares atípicas/adenocarcinoma invasor, 20,83% realizaram citopatologia de seguimento, e 16,67% e 12,50% das mulheres realizaram colposcopia e biópsia, respectivamente. Conclusão: A maioria das mulheres com exames citopatológicos alterados possivelmente não foi submetida às condutas preconizadas conforme as recomendações do Ministério da Saúde.

External quality control of cervical cytopathology: interlaboratory variability

OBJECTIVE

To compare the variability of screening tests held at laboratories with the Unit for External Quality Control (UEQC), checking the frequency of cases that were discordant, false-positive, false-negative, unsatisfactory or that had a delay in clinical management and diagnostic agreement.

MATERIALS AND METHODS

The study analyzed 10,053 screening tests from January 2007 to December 2008, including all positive cases, all those that fall under unsatisfactory and at least 10% of negative screening tests. The magnitude of the agreement was analyzed using the kappa coefficient.

RESULTS

Out of the 10,053 cases analyzed, 7.59% were considered disagreeing, and it was estimated that 1.1% were false-negative. There was a delay in the clinical procedure regarding 2.44% cases. There were 2.82% of cases identified as false-positive and 1.24% as unsatisfactory. The diagnostic agreement was excellent (kappa = 0.81). The agreement of most laboratories concerning screening tests was classified as very good. The agreement of the sample adequacy was reasonable (kappa = 0.30) and the agreement regarding the representation of epithelia was considered excellent.

CONCLUSION

Most laboratories showed very good agreement; however, it is worthy of note that to establish the standardization of diagnostic criteria, and enhance the accuracy of screening and improve the quality of cytopathology test results, it is necessary to perform external quality control.

Pharmaceutical Care for hypertensive patients provided within the Family Health Strategy in Goiânia, Goiás, Brazil

The aim of Pharmaceutical Care programs is to improve patients' quality of life, and such programs are particularly effective in the case of chronic diseases such as hypertension. The objective of this longitudinal study was to analyze a Pharmaceutical Care model for hypertensive patients receiving care within the Family Health Strategy (FHS). All patients were being seen by an FHS team affiliated to a primary healthcare unit in Goiânia, Goiás, Brazil. Fourteen patients participated in the study, with each patient receiving six home visits during the Pharmaceutical Care. Overall, 142 drug-related problems were reported, the most common concerning the ineffectiveness of treatment (33.8%). A total of 135 pharmaceutical interventions were performed, 92.6% of which involved pharmacist-patient communication, with 48.8% of these interventions being implemented. Cardiovascular risk decreased in three patients and remained unchanged in nine. In hypertensive patients with diabetes, fasting glucose levels were reduced in six out of nine cases. The Pharmaceutical Care model proposed here was effective in detecting drug-related problems and in proposing interventions to resolve or prevent these problems. Consequently, this may have contributed towards improving clinical parameters, such as fasting glucose levels and cardiovascular risk in hypertensive patients receiving care within the FHS.

Social inequalities in lawsuits for drugs

The aim of this study was to characterize the lawsuits requesting drugs considering the economic profile of their petitioners. All lawsuits (1378) accepted against Goiânia, GO from 2003 to 2007 were analyzed. Petitioners' demographic characteristics, reported diseases, requested drugs, origin of healthcare service, and lawsuit agent were described. Complainants' addresses were georeferenced and distributed into 4 regional groups classified in accordance with the population's average income. Dwellers of wealthier regions filed court actions requesting drugs more frequently, with an average rate of 1.7 lawsuits/1000 inhabitants versus 0.55/1000 in the poorer region. Lawsuit costs were 4-fold higher in wealthier regions compared with the poorest region. Chronic diseases were involved in most lawsuits, where acute and low complexity diseases predominated among complainants living in poorer regions. Thus, social differences were reflected in the granting of health rights.

[Quality of life in individuals exposed to cesium-137 in Goiânia, Goiás State, Brazil]

This cross-sectional observational study in Goiânia, Goiás State, Brazil in a sample of 56% of 111 individuals exposed to cesium-137 aimed to evaluate their quality of life and associations with socio-demographic factors. The study used the WHOQOL-BREF and the Monitoring System for Radiation Victims. Participants were divided according to international criteria: Group I - radiation dermatitis and / or cytogenetic dosimetry above 20 rads (n = 33) and Group II - cytogenetic dosimetry ≤ 20 rads (n = 29), totaling 62 subjects. Among the WHOQOL-BREF domains, environment showed the highest mean scores (59.88, SD = 20.39) and psychological the lowest (53.02, SD = 17.98). Associations between the physical, psychological, and social domains were significant for the age variable. There was no difference between groups. The association between socio-demographic factors and quality of life was not significant. Radiation victims suffer considerable impact on quality of life, with persistent psychosocial problems, especially among those older than 41 years.

Consumo de medicamentos por idosos, Goiânia, Brasil

OBJETIVO: Analisar o padrão de consumo de medicamentos entre idosos e sua associação com aspectos socioeconômicos e autopercepção de saúde. MÉTODOS: Estudo de base populacional e delineamento transversal com 934 idosos de Goiânia, GO, Brasil, entre dezembro de 2009 e abril de 2010. Os dados foram coletados por meio de questionário. As variáveis estudadas foram: número de medicamentos consumidos, sexo, estado civil, escolaridade, tipo de moradia, idade, renda e autopercepção de saúde. Os medicamentos foram classificados segundo o Anatomical Therapeutic and Chemical Classification. Os medicamentos impróprios para idosos foram identificados segundo o Critério de Beers-Fick. Os testes utilizados foram Qui-quadrado (X²) e exato de Fisher e p foi considerado significativo quando < 0,05. RESULTADOS: Os idosos consumiam 2.846 medicamentos (3,63 medicamentos/idoso). Os mais usuais atuavam no aparelho cardiovascular (38,6%). A prevalência de polifarmácia foi de 26,4% e da automedicação de 35,7%. Os medicamentos mais ingeridos por automedicação foram os analgésicos (30,8%); 24,6% dos idosos consumia medicamento considerado impróprio. Mulheres, viúvos, idosos com 80 anos ou mais e com pior autopercepção de saúde praticavam mais a polifarmácia. A maior prática da automedicação esteve associada com menor escolaridade e pior autopercepção de saúde. CONCLUSÕES: O padrão do consumo de medicamentos por idosos foi semelhante ao encontrado em idosos de outras regiões do Brasil. O número de medicamentos usados, a prevalência das práticas da polifarmácia e automedicação e consumo de medicamentos impróprios estiveram dentro da média nacional.

[Women with atypical, precursor lesions and invasive cervical cancer: behaviors according to the recommendations of the Ministry of Health]

PURPOSE

To verify whether women with atypias of undetermined significance and precursor lesions or invasive cervical outcomes were referred to Medium Complexity Units (MCU) following the guidelines recommended by the Brazilian Ministry of Health.

METHODS

Retrospective study based on the cytopathological outcomes of users of the Unified Health System, seen at Basic Health Assistance Units (BHAU) and referred to MCUs in the municipality of Goiânia, state of Goiás, from 2005 to 2006. We assessed 832 records according to the recommendations of the Brazilian Ministry of Health, as established by the Brazilian Nomenclature for Cervical Cytopathologic Outcomes and Recommended Clinical Practice. To check the distribution of variables such as reasons for referral, results of colposcopy and histopathology and clinical procedures we calculated absolute and relative frequencies, mean, minimum and maximum values.

RESULTS

We understood 72.7% of the referrals were not in accordance with the recommendations of the Ministry of Health. There were 605 women with test results classified as atypical squamous cells of undetermined significance, possibly non-neoplasms, and squamous intraepithelial lesion of low level which were sent to MCU, and of these 71.8% were submitted to colposcopy, and 64.7% had histopathological examination which results were classified as 31.0% with non-neoplasms and 44.6% as NIC I. Out of 211 women with results classified as more severe squamous lesions, 86.3% were submitted to colposcopy and 68.7% of these had histopathological examinations.

CONCLUSIONS

The results of this study revealed high rates of inappropriate referrals to MCU, which required a high percentage of unnecessary procedures. The recommendations of the Ministry of Health were followed by BHAU and the majority of women received counseling/treatment as recommended.

Atendimento pelo SUS na percepção de mulheres com lesões de câncer cervicouterino em Goiânia-GO

O câncer de colo do útero é prioridade nas políticas de saúde no Brasil. Apesar da existência do fluxo de atendimento estabelecido pelo Sistema Único de Saúde (SUS), fragilidades são observadas na sua operacionalização. Objetivou-se analisar a percepção de mulheres com lesões de colo do útero acerca do atendimento pelo SUS em Goiânia-GO. Estudo descritivo, exploratório de abordagem qualitativa. Os dados foram obtidos por meio de entrevistas, utilizando-se a técnica de incidente crítico e análise de conteúdo. Na percepção das mulheres, o atendimento é permeado por falhas no acolhimento, comunicação, assistência do profissional de saúde, falta de efetividade e pelo desconhecimento do próprio fluxo de atendimento. Evidenciou-se a necessidade de reorientação do atual modelo assistencial de atendimento, com abordagens conscientizadoras, que permitam aos profissionais e aos gestores desenvolverem habilidades de ouvir, acolher e de se responsabilizar pelo cuidado, a fim de promover a transformação dessa realidade.Descritores: Neoplasias do colo do útero; Saúde Pública; Percepção; Saúde da Mulher.

Atenção Farmacêutica em Goiânia: inserção do farmacêutico na Estratégia Saúde da Família

Com vistas no estabelecido na Política Nacional de Medicamentos, a Faculdade de Farmácia da UFG implantou, em parceria com a Secretaria Municipal de Saúde de Goiânia/Goiás, projeto de extensão universitária que propõe a inserção do farmacêutico na Estratégia Saúde da Família. Encontros foram realizados para sensibilização e apresentação do projeto às respectivas unidades de saúde, e a equipe de farmacêuticos local foi treinada para o exercício da atenção farmacêutica. Em 12 meses de desenvolvimento do projeto, 50 pacientes (70% femininos), com idade média de 50 anos, foram assistidos. Entre estes, 40 (80%) apresentavam mais de uma enfermidade associada e 46 (92%) faziam o uso de dois ou mais fármacos, simultaneamente prescritos. Foram detectados 154 Problemas Relacionados com Medicamentos (PRM), com incidência de 3,1 PRM por paciente. O PRM mais frequente foi a falta de efetividade na terapêutica (49%), sendo 26,3% desses devido à falta de adesão ao tratamento. Conclui-se que a problemática envolvida na assistência à saúde devido à falta de eficiência da farmacoterapia assume dimensões importantes. Atenção Farmacêutica como estratégia de Assistência Farmacêutica mostrou-se, potencialmente, capaz de melhorar a assistência à saúde dos usuários do SUS.

Avaliação da Eficiência de Três Métodos Utilizados como Controle da Qualidade dos Exames Citopatológicos Cervicais Classificados como Negativos no Escrutínio de Rotina

O exame citopatológico é o método mais utilizado para prevenção e detecção precoce de câncer cervical. Mas os resultados falso-negativos ainda são um dos grandes problemas dos laboratórios de citopatologia. O método de revisão aleatória de 10% dos esfregaços interpretados previamente como negativos tem sido o mais utilizado como controle interno da qualidade, no entanto, com pouca eficiência. Assim, o objetivo deste estudo foi comparar a eficiência da revisão rápida de 100%, revisão de esfregaços selecionados com base em critérios clínicos e revisão aleatória de 10% como métodos de controle interno da qualidade dos esfregaços cervicais negativos no escrutínio de rotina. Teve como base a população feminina usuária do Sistema Único de Saúde de Goiânia-GO, que se submeteu ao exame citopatológico realizado no Laboratório de Análises Clínicas Rômulo Rocha da Faculdade de Farmácia da Universidade Federal de Goiás. Os 5.530 esfregaços classificados como negativos no escrutínio de rotina foram submetidos ao método de revisão rápida de 100%, em seguida, foram selecionados os esfregaços com base em critérios clínicos e, por último, 10% do total de esfregaços negativos e submetidos aos respectivos métodos de revisões. Todas as etapas foram às cegas e os resultados classificados de acordo com o Sistema de Bethesda. A revisão rápida de 100% identificou 141 esfregaços suspeitos, desses, 84 (59,6%) foram considerados alterados pelo diagnóstico final, dos quais 36 (25,5%) foram classificados como células escamosas atípicas de significado indeterminado (ASC-US), cinco (3,5%) como células escamosas atípicas, não podendo excluir lesão de alto grau (ASC-H), 34 (24,1%) como lesão intra-epitelial escamosa de baixo grau (LSIL), seis (4,3%) como lesão intra-epitelial de alto grau (HSIL) e três (2,1%) células glandulares atípicas (AGC). Dos 1.279 esfregaços revisados com base em critérios clínicos, 19 (79,2%) foram confirmados como alterados pelo diagnóstico final, sendo nove (47,3%) classificados como ASC-US, um (5,3%) ASC-H, oito (42,1%) LSIL e um (5,3%) HSIL. Dos 560 esfregaços analisados pela revisão de 10%, seis (46,2%) foram confirmados pelo diagnóstico final, sendo quatro (30,8%) classificados como ASC-US, um (7,7%) LSIL e um (7,7%) HSIL. Portanto a revisão rápida de 100% é um método de controle interno da qualidade mais eficiente na detecção de resultados falso-negativos dos exames citopatológicos, do que a revisão com base em critérios clínicos e revisão aleatória de 10%.

Controle da Qualidade em Citopatologia Cervical: Revisão de Literatura

O exame citopatológico é importante ferramenta para a detecção das lesões precursoras do câncer do colo uterino que, naquele momento, são tratáveis, resultando em significante decréscimo da mortalidade. Entretanto, o exame citopatológico apresenta falhas, pois a taxa de resultados falso-negativos pode variar de 2% a 50%. Os resultados falso-negativos ocorrem principalmente devido a erro de coleta, de escrutínio e de interpretação. O controle interno e o externo da qualidade na rotina dos laboratórios têm como objetivo final melhorar o desempenho diagnóstico do exame citopatológico, além de possibilitar a avaliação do desempenho do escrutinador e a identificação de causas de erros relacionados à coleta. O controle interno da qualidade pode ser realizado regularmente e abrange o monitoramento da adequabilidade da amostra, a observação do tempo de escrutínio, o controle da carga de trabalho do escrutinador, a revisão hierárquica dos esfregaços e a revisão dos esfregaços negativos. O controle interno de qualidade também pode compreender a análise da correlação cito-histológica, a revisão de exames anteriores, o monitoramento estatístico da freqüência das lesões e da adequabilidade da amostra, a inclusão proposital de esfregaços anormais na rotina. Educação continuada, qualificação do pessoal e exame de proficiência periódico são estratégias a serem adotadas. Revisão aleatória ou total dos exames, revisão rápida ou detalhada são métodos que têm vantagens e desvantagens na detecção dos resultados falso-negativos. Cabe ao laboratório definir a melhor estratégia de controle interno da qualidade que permita a melhoria do processo técnico e, conseqüentemente, da qualidade do serviço dos laboratórios de citopatologia.  

Whole, Turret and step methods of rapid rescreening: is there any difference in performance?

We compared the performance of the Whole, Turret and Step techniques of 100% rapid rescreening (RR) in detection of false-negatives in cervical cytology. We tested RR performance with cytologists trained and among those without training. We revised 1,000 consecutive slides from women participating in an ongoing international screening trial. Two teams of experienced cytologists performed the RR techniques: one trained in RR procedures and the other not trained. The sensitivities in the trained group were Whole 46.6%, Turret 47.4% and Step 50.9%; and in the non-trained group were 38.6, 31.6 and 47.4%, respectively. The kappa coefficient showed a weak agreement between the two groups of cytologists and between the three RR techniques. The RR techniques are more valuable if used by trained cytologists. In the trained group, we did not observe significant differences between the RR techniques used, whereas in the non-trained group, the Step technique had the best sensitivity.

Evaluation of 100% rapid rescreening of negative cervical smears as a quality assurance measure

OBJECTIVE

The objective of this study was to compare the performance of 100% rapid rescreening, 10% random rescreening and the review of smears selected on the basis of clinical criteria, as a method of internal quality control of cervical smears classified as negative during routine screening.

METHODS

A total of 3149 smears were analysed, 173 of which were classified as positive and 2887 as negative, while 89 smears were considered unsatisfactory. The smears classified as negative were submitted to 100% rapid rescreening, 10% random rescreening, and rescreening based on clinical criteria. The rescreening stages were blinded and results were classified according to the Bethesda 2001 terminology. Six cytologists participated in this study, two of whom were responsible for routine screening while the other four alternated in carrying out rescreening so that no individual reviewed the same slide more than once.

RESULTS

The 100% rapid rescreening method identified 92 suspect smears, of which 42 were considered positive at final diagnosis. Of the 289 smears submitted to the 10% rescreening method, four were considered abnormal but only one was confirmed positive in the final diagnosis. Of the 690 smears rescreened on the basis of clinical criteria, 10 were considered abnormal and eight received a positive final diagnosis.

CONCLUSIONS

The 100% rapid rescreening method is more efficient at detecting false-negative results than 10% random rescreening or rescreening on the basis of clinical criteria, and is recommended as an internal quality control method.

Quality assurance in cervical smears: 100% rapid rescreening vs. 10% random rescreening

OBJECTIVE

To compare 100% rapid rescreening of cervical smears with 10% random rescreening as a method of quality assurance.

STUDY DESIGN

A total of 5215 smears, randomly selected from smears reported as negative by cytotechnologists during routine screening, underwent 100% rapid rescreening by senior cytotechnologists. Ten percent of these smears, selected at random, were rescreened by other senior cytotechnologists. The gold standard was defined by cytopathologists, who rescreened all 5215 smears. After excluding unsatisfactory smears detected by cytopathologists, 4271 were included in the analysis.

RESULTS

The 100% rapid rescreening method identified 69.9%, 95.7% and 100%, respectively, of atypical squamous cells of undetermined significance, low grade squamous intraepithelial lesion and high grade squamous intraepithelial lesion cases reported by the cytopathologists. The 100% rapid rescreening method showed a sensitivity of 73.5% and specificity of 98.6%. The 10% rescreening method showed sensitivity of 40.9% and specificity of 98.8%.

CONCLUSION

One hundred percent rapid rescreening is an efficient method of internal quality assurance in cervical smear diagnosis. It can reduce the false negative rate and therefore can provide greater certainty to women who have received negative results. Well-trained cytotechnologists are able to identify abnormal smears in 1-minute rapid rescreening.

Human papillomavirus prevalence among women with cervical intraepithelial neoplasia III and invasive cervical cancer from Goiânia, Brazil

This study estimated the prevalence and distribution of human papillomavirus (HPV) types among women with cervical intraepithelial neoplasia (CIN) grade III and invasive cervical cancer from Goi s (Brazil Central Region). Seventy-four cases were analyzed and consisted of 18 CIN III, 48 squamous cell carcinomas, 4 adenocarcinomas, 1 adenosquamous carcinoma and 3 undifferentiated carcinomas. HPV-DNA sequences were examined in formalin-fixed and paraffin-embedded tissues using primers from L1 region GP5+/GP6+. Polymerase chain reaction products were typed with dot blot hybridization using probes for HPV 16, 18, 31, 33, 45, 54, 6/11, 42/43/44, 51/52, 56/58. The prevalence of HPV was estimated to be 76% (56/74). HPV 16 was the most frequently found type, followed by HPV 33, 18 and 31. The prevalence of untyped HPV was 6%; 79% percent of the squamous cell carcinoma cases and 61% percent of the CIN III were positive for HPV and the prevalence rate of HPV types was the same for the total number of cases. According to other studies, HPV type 16 is the most prevalent virus in all Brazilian regions, but there is variation regarding to other types. Type 18 is the second most prevalent HPV in North, Southeast and South Brazil regions and types 31 and 33 are the second most prevalent HPV in Northeast and Central Brazil, respectively.

Subcellular localization of myosin-V in the B16 melanoma cells, a wild-type cell line for the dilute gene

The discovery that the dilute gene encodes a class V myosin led to the hypothesis that this molecular motor is involved in melanosome transport and/or dendrite outgrowth in mammalian melanocytes. The present studies were undertaken to gain insight into the subcellular distribution of myosin-V in the melanoma cell line B16-F10, which is wild-type for the dilute gene. Immunofluorescence studies showed some degree of superimposed labeling of myosin-V with melanosomes that predominated at the cell periphery. A subcellular fraction highly enriched in melanosomes was also enriched in myosin-V based on Western blot analysis. Immunoelectron microscopy showed myosin-V labeling associated with melanosomes and other organelles. The stimulation of B16 cells with the alpha-melanocyte-stimulating hormone led to a significant increase in myosin-V expression. This is the first evidence that a cAMP signaling pathway might regulate the dilute gene expression. Immunofluorescence also showed an intense labeling of myosin-V independent of melanosomes that was observed within the dendrites and at the perinuclear region. Although the results presented herein are consistent with the hypothesis that myosin-V might act as a motor for melanosome translocation, they also suggest a broader cytoplasmic function for myosin-V, acting on other types of organelles or in cytoskeletal dynamics.
