Mobile application-based oximetry: a potential toolfor appropriate referral of patients with respiratory symptoms examined via telemedicine.

OBJECTIVE: To calculate the positive likelihood ratio to determine whether telemedicine is able to optimize referral to the emergency department. METHODS: Unicenter study with 182 consecutive patients admitted to Hospital Israelita Albert Einstein due to respiratory symptoms. All patients were submitted to oxygen saturation measurement using the standard method Welch Allyn finger device vital sign monitor and a 2-minute evaluation (Binah.ai mobile application). The reproducibility of oxygen saturation measurements made with both methods was investigated using interclass correlation coefficients and analysis of dispersion. Bland-Altman plots were constructed and kappa concordance coefficients used to examine data normality. Accuracy was also estimated. RESULTS: Oxygen saturation measurement differences between methods were ≤2% in more than 85% of cases. The mean difference (bias) between methods was near zero (0.835; Bland-Altman analysis). Oxygen saturation measurements made using the Binah.ai mobile application had an average ability to detect patients with altered oxygen saturation levels compared to the conventional method (ROC analysis). The positive likelihood ratio of the mobile application was 6.23. CONCLUSION: Mobile applications for oxygen saturation measurement are accessible user-friendly tools with moderate impact on clinical telemedicine evaluation of patients with respiratory symptoms, and may optimize referral to the emergency department.

Retinal exams requested at Primary Care Unit: indications, results and alternative strategies of evaluation.

OBJECTIVE: To evaluate indications, results and strategy of retinal exams requested at Primary Care Units. METHODS: A retrospective study that analyzed the indications and results of retinal exams, in the modalities clinical dilated fundus exams and color fundus photographs. In the following situations, patients were considered eligible for color fundus photographs if visual acuity was normal and ocular symptoms were absent: diabetes mellitus and/or hypertension, in use of drugs with potential retinal toxicity, diagnosis or suspicion of glaucoma, stable and asymptomatic retinopathies, except myopia greater than -3.00 diopters. RESULTS: A total of 1,729 patients were evaluated (66% female, age 63.5±15.5 years), and 1,190 underwent clinical dilated fundus exam and 539 underwent color fundus photographs. Diabetes was present in 32.2%. The main indications were diabetes (23.7%) and glaucoma evaluation (23.5%). In 3.4% of patients there was no apparent indication. The main results were a large cup/disc ratio (30.7%) and diabetic retinopathy (13.2%). Exam was normal in 9.6%, detected peripheral changes in 7% and could not be performed in 1%. Considering patients eligible for fundus photographs (22.4%), more than half underwent clinical dilated fundus exams. CONCLUSION: Regarding exam modality, there were no important differences in the distribution of indications or diagnosis. Color fundus photograph is compatible with telemedicine and more cost-effective, and could be considered the strategy of choice in some scenarios. Since there are no clear guidelines for retinal exams indications or the modality of choice, this study may contribute to such standardization, in order to optimize public health resources.

Structural and functional analyses of the optic nerve and lateral geniculate nucleus in glaucoma.

PURPOSE: To analyze the correlation between structural characteristics of intraorbital optic nerve (ION) and lateral geniculate nucleus (LGN) measured by 3-Tesla magnetic resonance imaging (3T MRI), and the severity of glaucomatous damage. METHODS: In this cross-sectional study, 41 glaucoma patients and 12 age- and sex-matched controls underwent standard automated perimetry (SAP) and frequency doubling technology (FDT) as functional evaluation; optic disc stereophotograph, spectral-domain optical coherence tomography (OCT) and confocal scanning laser tomography as ocular structural evaluation; and 3T MRI. Structure-structure and structure-function correlation were performed using bootstrap resampling method for clustered data. RESULTS: The ION mean diameter and cross-sectional area were different between glaucoma and control groups at 5mm and 10mm (all, p≤0.011) from the globe, but not at 15mm (both, p≥0.067). LGN height was significantly lower in glaucoma group (p = 0.005). OCT rim area and functional parameters (SAP and FDT) correlated significantly with all ION segments, showing stronger correlations at 10 and 15 mm. ION parameters at 10 and 15 mm presented mild-to-moderate correlation with OCT peripapillary nerve fiber layer thickness, and ION at 15mm had mild association with the neuroretinal rim area on stereophotographs. Although LGN height was significantly smaller in glaucoma group (p = 0.005), LGN parameters were not associated with any ocular structural or functional parameter. CONCLUSION: Assessment of central and peripheral nervous systems using 3T MRI confirmed that glaucoma patients had smaller ION dimensions and LGN height compared to the control group. In general, ION dimensions presented mild to moderate correlations with functional and ocular structural parameters. Although ION had significant correlations at any distance from the eye, the ION distal locations correlated better with OCT results and functional parameters. However, LGN parameters were not associated with functional or ocular structural parameters.

Psychophysical Measurements of Luminance Contrast Sensitivity and Color Discrimination with Transparent and Blue-Light Filter Intraocular Lenses.

INTRODUCTION: The purpose of this study was to measure luminance contrast sensitivity and color vision thresholdfs in normal subjects using a blue light filter lens and transparent intraocular lens material. METHODS: Monocular luminance grating contrast sensitivity was measured with Psycho for Windows (version 2.36; Cambridge Research Systems) at 3.0, 6.0, 12.0, 20.0, and 30.0 cycles per degree of visual angle (cpd) in 15 normal subjects (eight female), with a mean age of 21.6 years (SD = 3.8 years). Chromatic discrimination was assessed with the Cambridge colour test (CCT) along the protan, deutan, and tritan color confusion axes. Both tests were performed in a darkened room under two situations: with a transparent lens and with blue light filter lens. Subjective impressions were taken by subjects regarding their visual experience under both conditions. RESULTS: No difference was found between the luminance contrast sensitivity measured with transparent and blue light filter. However, 13/15 (87%) of the subjects reported more comfortable vision with the blue filter. In the color vision test, tritan thresholds were significantly higher for the blue filter compared with the transparent filter (p = 0.003). For protan and deutan thresholds no differences were found. CONCLUSION: Blue-yellow color vision is impaired with the blue light filter, and no impairment occurs with the transparent filter. No significant differences in thresholds were found in the luminance contrast sensitivity comparing the blue light and transparent filters. The impact of short wavelength light filtering on intrinsically photosensitive retinal ganglion cells is also discussed.

Vision status, ophthalmic assessment, and quality of life in the very old.

PURPOSE: To determine the vision status, ophthalmic findings, and quality of life among the very elderly. METHODS: This was a cross-sectional observational study of individuals aged 80 years and above. A comprehensive ophthalmic exam was performed with mea surement of both the presenting (PVA) and best-corrected visual acuity. The Quality of Life Short Form-36 (SF-36) and the Visual Function Questionnaire (VFQ-25) were also administered. RESULTS: A total of 150 non-institutionalized participants were assigned to three age groups: 80-89 years (n=70), 90-99 years (n=50), and 100 years and older (n=30). PVA and best-corrected visual acuity were normal (≥20/30) in 20 (13.3%) and 37 participants (24.7%), respectively. Regarding PVA, mild visual impairment (<20/30 to ≥20/60) was found in in 53 (35.4%), moderate visual impairment (<20/60 to ≥20/200) in 50 (33.3%), severe visual impairment (<20/200 to ≥20/400) in 8 (5.3%), and blindness (<20/400) in 19 (12.7%) participants. Regarding best-corrected visual acuity, mild, moderate, and severe visual impairments were present in 55 (36.7%), 38 (25.3%), and 5 (3.3%) participants, respectively, and blindness was present in 15 (10%). The main causes of visual impairment/blindness were cataract (43.8%), refractive errors (21.5%), age-related macular degeneration (17.7%), and myopic degeneration (3.8%). SF-36 scores were worse in those with low visual acuity, while VFQ-25 domain scores were poorer in those with vision impairment/blindness. CONCLUSION: Vision impairment and blindness was present in three-quarters of this sample, but it was notable that adequate correction with spectacles improved visual acuity. This reinforces the need for regular ophthalmic care in elderly patients to improve their quality of life by optimizing vision.

ABSTRACT Objective To describe retinal diseases found in patients who were waiting for treatment at a tertiary care hospital in Rio Branco, Acre, Brazil. Methods Patients underwent slit lamp biomicroscopy, dilated fundus exam and ocular ultrasound. Patients were classified according to phakic status and retinal disease of the most severely affected eye. Results A total of 138 patients were examined. The mean age was 51.3 years. Diabetes was present in 35.3% and hypertension in 45.4% of these patients. Cataract was found in 23.2% of patients, in at least one eye. Retinal examination was possible in 129 patients. The main retinal diseases identified were rhegmatogenous retinal detachment (n=23; 17.8%) and diabetic retinopathy (n=32; 24.8%). Out of 40 patients evaluated due to diabetes, 13 (32.5%) had absent or mild forms of diabetic retinopathy and did not need further treatment, only observation. Conclusion Diabetic retinopathy was the main retinal disease in this population. It is an avoidable cause of blindness and can be remotely evaluated, in its initial stages, by telemedicine strategies. In remote Brazilian areas, telemedicine may be an important tool for retinal diseases diagnosis and follow-up.

Georeferencing deaths from stroke in São Paulo: an intra-city stroke belt?

BACKGROUND: The role of socioeconomic status in the worldwide stroke burden has been studied with various methods using vital statistics and research-generated data. AIM: The objective of our study was to describe the stroke mortality rates and the stroke mortality distribution, and to evaluate the association between stroke mortality rates and geographical distribution with the human development index in São Paulo, Brazil. METHODS: This ecological study evaluated a historical series of stroke mortality in São Paulo, Brazil, from 2004 to 2010. Standard stroke mortality rate per 100 000 inhabitants at each year, the address of residence assumed as the place of living, and the human development index applied as a social indicator were used in order to evaluate if stroke mortality correlated with socioeconomic status. RESULTS: The mean standardized stroke mortality in São Paulo decreased from 66 to 46·7 per 100 000 inhabitants from 2004 to 2010. Stroke mortality differed according to human development index strata with an almost three times higher stroke mortality in the lowest when compared with the highest human development index stratum. Visual inspection of the map of the districts with high stroke mortality disclosed regional clusters with high mortality in the east, northwest, and south regions, a finding suggestive of the presence of a stroke belt inside the city of São Paulo. CONCLUSIONS: In conclusion, between 2004 and 2010, stroke mortality rates decreased by 28·5% in São Paulo. A geographical pattern in stroke mortality could be observed, with considerable differences according the human development index level of the place of living.

Association between participation and compliance with Continuing Medical Education and care production by physicians: a cross-sectional study.

OBJECTIVE: Physician participation in Continuing Medical Education programs may be influenced by a number of factors. To evaluate the factors associated with compliance with the Continuing Medical Education requirements at a private hospital, we investigated whether physicians' activity, measured by volumes of admissions and procedures, was associated with obtaining 40 Continuing Medical Education credits (40 hours of activities) in a 12-month cycle. METHODS: In an exclusive and non-mandatory Continuing Medical Education program, we collected physicians' numbers of hospital admissions and numbers of surgical procedures performed. We also analyzed data on physicians' time since graduation, age, and gender. RESULTS: A total of 3,809 credentialed, free-standing, private practice physicians were evaluated. Univariate analysis showed that the Continuing Medical Education requirements were more likely to be achieved by male physicians (odds ratio 1.251; p=0.009) and who had a higher number of hospital admissions (odds ratio 1.022; p<0.001). Multivariate analysis showed that age and number of hospital admissions were associated with achievement of the Continuing Medical Education requirements. Each hospital admission increased the chance of achieving the requirements by 0.4%. Among physicians who performed surgical procedures, multivariate analysis showed that male physicians were 1.3 time more likely to achieve the Continuing Medical Education requirements than female physicians. Each surgical procedure performed increased the chance of achieving the requirements by 1.4%. CONCLUSION: The numbers of admissions and number of surgical procedures performed by physicians at our hospital were associated with the likelihood of meeting the Continuing Medical Education requirements. These findings help to shed new light on our Continuing Medical Education program.

Objetivo A participação de médicos em programas de Educação Médica Continuada pode ser influenciada por inúmeros fatores. Para avaliar os fatores associados ao cumprimento dos requisitos para Educação Médica Continuada em um hospital privado, investigamos se a atividade médica, medida por volume de internações e procedimentos, esteve relacionada à obtenção de 40 créditos (40 horas-aula) em um ciclo do programa de 12 meses. Métodos Em um programa exclusivo e não obrigatório de Educação Médica Continuada, coletamos o número de admissões e de procedimentos realizados por médico. Analisamos dados como tempo de formado, idade e sexo. Resultados Foram analisados dados de 3.809 médicos credenciados e autônomos. A análise univariada mostrou que os requisitos de Educação Médica Continuada eram mais preenchidos por médicos do sexo masculino (odds ratio de 1,251; p=0,009) e que eles apresentavam números de internações mais significativos (odds ratio de 1,022; p<0,001). A análise multivariada mostrou que idade e número de admissões estiveram associados ao cumprimento das metas estabelecidas. Cada admissão aumentou a chance de atingir a meta em 0,4%. Entre os que realizaram procedimentos cirúrgicos, a análise multivariada mostrou que médicos do sexo masculino eram 1,3 vez mais propensos a atingir a meta estabelecida que seus pares do sexo feminino. Cada procedimento cirúrgico realizado elevou a chance de atingir a meta em 1,4%. Conclusão O número de admissões e de procedimentos cirúrgicos realizados por médicos em nosso hospital foi associado à probabilidade de alcançar a meta de Educação Médica Continuada. Estes achados lançaram uma nova luz sobre o nosso programa de Educação Médica Continuada. .

Os indicadores propostos para a avaliação do atendimento foram: taxa de óbito no pronto atendimento; tempo médio de permanência dos pacientes dentro da unidade; taxa de consulta de retorno não programado; taxa de internação dos pacientes com triagem 1 segundo o Índice de Severidade de Emergência; taxa de atendimento médico não finalizado; taxa de reclamações; e tempo porta-eletrocardiograma. Resultados A taxa de óbito no pronto atendimento foi zero. Cinco dos 22 pacientes triados como 1 segundo o Índice de Severidade de Emergência (22,7%) chegaram em situação de parada cardiorrespiratória. Todos foram submetidos ao tratamento de reanimação cardiopulmonar com o reestabelecimento de suas funções vitais. O tempo médio de permanência dos pacientes dentro da unidade foi de 3 horas, 33 minutos e 7 segundos. A taxa de retornos em consulta médica não programados no Pronto Atendimento da Unidade Ibirapuera foi de 13,64%. Foi observada taxa de reclamações de 2,8/1.000 atendimentos realizados (183 reclamações) no período analisado. Conclusão O modelo de atendimento de urgência e emergência de unidades avançadas ...

Advanced units: quality measures in urgency and emergency care.

OBJECTIVE: To evaluate, through care indicators, the quality of services rendered to patients considered urgency and emergency cases at an advanced emergency care unit. METHODS: We analyzed data from managerial reports of 64,891 medical visits performed in the Emergency Care Unit of the Ibirapuera Unit at Care during the period from June 1st, 2012 through May 31st, 2013. The proposed indicators for the assessment of care were rate of death in the emergency care unit; average length of stay of patients in the unit; rate of unplanned return visits; admission rate for patients screened as level 1 according to the Emergency Severity Index; rate of non-finalized medical consultations; rate of complaints; and door-to-electrocardiogram time. RESULTS: The rate of death in the emergency care unit was zero. Five of the 22 patients classified as Emergency Severity Index 1 (22.7%) arrived presenting cardiac arrest. All were treated with cardiopulmonary resuscitation and reestablishment of vital functions. The average length of stay of patients in the unit was 3 hours, 33 minutes, and 7 seconds. The rate of unscheduled return visits at the emergency care unit of the Ibirapuera unit was 13.64%. Rate of complaints was 2.8/1,000 patients seen during the period. CONCLUSION: The model of urgency and emergency care in advanced units provides an efficient and efficaious service to patients. Both critically ill patients and those considered less complex can receive proper treatment for their needs.

Effect of implementing an acute myocardial infarction guideline on quality indicators.

OBJECTIVE: To evaluate the compliance rates to quality of care indicators along the implementation of an acute myocardial infarction clinical practice guideline. METHODS: A clinical guideline for acute myocardial infarction was introduced on March 1st, 2005. Patients admitted for acute myocardial infarction from March 1st, 2005 to December 31st, 2012 (n=1,431) were compared to patients admitted for acute myocardial infarction before the implementation of the protocol (n=306). Compliance rates to quality of care indicators (ASA prescription on hospital admission and discharge, betablockers on discharge and door-to-balloon time) as well as the length of hospital stay and in-hospital mortality were compared before and after the implementation of the clinical guideline. RESULTS: The rates of ASA prescription on admission, on discharge and of betablockers were higher after guideline implementation: 99.6% versus 95.8% (p<0.001); 99.1% versus 95.8% (p<0.001); and 95.9% versus 81.7% (p<0.001), respectively. ASA prescription rate increased over time, reaching 100% from 2009 to 2012. Door-to-balloon time after versus before implementation was of 86(32) minutes versus 93(51) (p=0.20). The length of hospital stay after the implementation versus before was of 6(6) days versus 6(4) days (p=0.34). In-hospital mortality was 7.6% (before the implementation), 8.7% between 2005 and 2008, and 5.3% between 2009 and 2012, (p=0.04). CONCLUSION: The implementation of an acute myocardial infarction clinical practice guideline was associated with an increase in compliance to quality of care indicators.

Efeito da implementação de um protocolo assistencial de infarto agudo do miocárdio sobre os indicadores de qualidade / Effect of implementing an acute myocardial infarction guideline on quality indicators

OBJETIVO: Avaliar a adesão aos indicadores de qualidade assistencial ao longo da implementação de um protocolo assistencial de infarto agudo do miocárdio. MÉTODOS: Em 1º de março de 2005 foi implementado o protocolo assistencial de infarto agudo do miocárdio. Foram selecionados pacientes admitidos de 1ºde março de 2005 a 31 de dezembro de 2012 (n=1.431). Para comparação, utilizamos os dados de pacientes admitidos por infarto na fase pré-protocolo (n=306). Comparamos a taxa de adesão aos indicadores (taxa de prescrição de AAS na admissão hospitalar e na alta hospitalar, betabloqueador na alta e tempo porta-balão) entre as fases pré e pós-implementação do protocolo, além de tempo de permanência hospitalar e mortalidade intra-hospitalar nas diferentes fases. RESULTADOS: As taxas de prescrição de AAS na admissão e na alta hospitalar, e de betabloqueador foram maiores na fase pós versus a pré-implementação do protocolo: 99,6% versus 95,8% (p<0,001); 99,1% versus 95,8% (p<0,001) e 95,9% versus 81,7% (p<0,001), respectivamente. A taxa de prescrição de AAS aumentou ao longo da implementação do protocolo, atingindo 100% de 2009 a 2012. O tempo porta-balão pós versus pré foi de 86(32) minutos versus 93(51), respectivamente (p=0,20). O tempo de permanência hospitalar foi semelhante na fase pré versus pós-protocolo: 6(6) dias versus 6(4) dias (p=0,34). A mortalidade intra-hospitalar foi de 7,6% no pré-protocolo, 8,7% entre 2005 e 2008 e 5,3% entre 2009 e 2012 (p=0,04). CONCLUSÃO: A implementação do protocolo assistencial refletiu-se na maior adesão aos indicadores de qualidade.
