RESUMO
Abstract Background Telemedicine allows Parkinson disease (PD) patients to overcome physical barriers to access health care services and increases accessibility for people with mobility impairments. Objective To investigate the feasibility indicators of a telehealth intervention for PD patients, including patient recruitment, attendance, technical issues, satisfaction, and benefits on levels of physical activity and sleep. Methods We conducted a single-center, single-arm study of telehealth video consultations using WhatsApp (Meta Platforms, Inc., Menlo Park, CA, USA). Also, we collected the feasibility indicators as the primary endpoints. All the patients in the study were previously evaluated in person by the same team. Results Patient recruitment, attendance, and technical issues rates were 61.3%, 90.5%, and 13.3%, respectively, with good scores of patient acceptance and satisfaction with the study intervention. The telehealth intervention improved physical activity, including the number of walks for at least 10 continuous minutes (p = 0.009) and the number of moderate-intensity activities lasting at least 10 continuous minutes (p = 0.001). The Pittsburgh sleep quality index (PSQI) scores also improved for one of its components: perceived sleep duration (p < 0.001) and for total Pittsburgh score (p < 0,001). The average travel time saving was 289.6 minutes, and money-saving was R$106.67 (around USD 18; almost 10% of the current minimum wage in Brazil). Conclusions Direct-to-patient telehealth video consultations proved to be feasible and effective and had a positive impact on physical activity levels and sleep in PD patients.
Resumo Antecedentes A telemedicina permite que pacientes com doença de Parkinson (DP) superem barreiras físicas para acessar serviços de saúde e aumenta a acessibilidade para pessoas com mobilidade reduzida. Objetivo Investigar indicadores de viabilidade de uma intervenção em telessaúde para pacientes com DP, incluindo recrutamento, atendimento, aderência, problemas técnicos, satisfação e benefícios nos níveis de atividade física e sono. Métodos Foi conduzido um estudo de centro e braço únicos baseado em consultas por telessaúde com utilização do WhatsApp (Meta Platforms, Inc., Menlo Park, CA, EUA). Foram calculados indicadores de viabilidade como desfechos primários. Resultados As taxas de recrutamento, atendimento e problemas técnicos foram 61,3%, 90,5% e 13,3%, respectivamente, com bons escores de aceitação e satisfação com a intervenção. A intervenção melhorou os níveis de atividade física, incluindo o número de passos por pelo menos 10 minutos contínuos (p = 0,009) e o número de atividades intensas e moderadas com duração de pelo menos 10 minutos contínuos (p = 0,001). O Índice de Qualidade do Sono de Pittsburgh melhorou nos seguintes componentes: duração percebida do sono (p < 0,001) e escore total (p < 0,001). A média do tempo de viagem médio poupado foi de 289,6 minutos, e a economia financeira foi de R$ 106,67 reais (por volta de USD 18; quase 10% do salário mínimo atual do Brasil). Conclusões As consultas por vídeo provaram ser viáveis e efetivas, com impacto positivo nos níveis de atividade física e sono de pacientes com DP.
RESUMO
Abstract Introduction: It is challenging to diagnose syncope in patients with pacemakers. Because these patients have increased morbidity and mortality risks, they require immediate attention to determine the causes in order to provide appropriate treatment. This study aimed to investigate the causes and predictive factors of syncope as well as the methods used to diagnose syncope in cardiac pacemaker patients. Methods: Patients with pacemakers implanted owing to sinus node disease or atrioventricular block were evaluated with standardized questionnaires, endocavitary electrograms, and other tests based on the suspected causes of syncope. Mann-Whitney U tests were used to analyze continuous variables and Chi-squared or Fisher's exact tests were used for categorical variables. Logistic regression was used for multivariate analyses. Statistical significance was P<0.05. Results: The study included 95 patients with pacemakers: 47 experienced syncope in the last 12 months and 48 did not. Of the 100 documented episodes of syncope, 48.9% were vasovagal syncopes, 17% had cardiac-related causes, 10.6% had unknown causes, and 8.5% had pacemaker failure. The multivariate analysis showed that a New York Heart Association (NYHA) Functional Class II was a significant factor for developing syncope (P<0.01). Conclusion: While the most common type of syncope in pacemaker patients was neurally mediated, it is important to perform detailed evaluations in this population as the causes of syncope can be life-threatening. The best diagnostic methods were stored electrogram analysis and the tilt table test. NYHA Functional Class II patients were found to have a higher risk for syncope.
