ABSTRACT
SUMMARY OBJECTIVE: The objectives of this study were to translate and cross-culturally adapt the telehealth usability questionnaire into Brazilian Portuguese and to evaluate its psychometric properties. METHODS: This was a methodological validation study carried out in two phases. In phase 1, the telehealth usability questionnaire was cross-culturally adapted with 10 participants comprising the expert committee members, including 5 healthcare professionals with theoretical and practical knowledge of telehealth, 1 methodologist, and 4 translators. This phase was performed at Universidade Federal de Juiz de Fora Physiotherapy Clinic School. In phase 2, the psychometric properties of telehealth usability questionnaire Brazil were analyzed. This phase included in-person assessments at Márcio Cunha Hospital, Minas Gerais. The recruitment period for both phases was from April 2020 to February 2021. Content validity, reliability, internal consistency, and criterion validity were analyzed. The criterion validity was evaluated using correlation with a validated instrument: the system usability scale. RESULTS: The telehealth usability questionnaire was adequately translated and cross-culturally adapted. The telehealth usability questionnaire Brazil presented an excellent content validity index of 0.96 with percentages of understanding higher than 90%. The telehealth usability questionnaire Brazil demonstrated great internal consistency (α=0.94 and ω=0.94), excellent intra-rater reliability (intraclass correlation coefficient=0.85, 95%CI 0.75-0.91), no difference between the test and retest [T (0.425), p>0.673], and no proportional bias (p=0.205). There was a moderate correlation between telehealth usability questionnaire Brazil and the system usability scale (r=0.52, p<0.0001). CONCLUSION: The telehealth usability questionnaire was adequately translated and cross-culturally adapted into Brazilian Portuguese and showed adequate psychometric properties for use in telehealth clinical practice and research in Brazilian-Portuguese-speaking individuals.
ABSTRACT
Introdução: A doença pulmonar obstrutiva crônica (DPOC) possui alta prevalência e gera altos custos aos sistemas de saúde. A reabilitação pulmonar (RP) é uma intervenção não-farmacológica que gera benefícios clínicos para os pacientes e economia de gastos para o sistema de saúde devido a redução do número de exacerbações da doença e internações hospitalares. Embora fortemente recomendada, a RP tem sido subutilizada havendo um baixo índice de indicações. Objetivo: Identificar as barreiras e os facilitadores para o encaminhamento de pacientes com DPOC à RP e à prática de atividade física. Métodos: Estudo qualitativo, realizado com médicos atuantes na atenção primária à saúde (APS) e uso de entrevistas semiestruturadas. As entrevistas foram gravadas e transcritas literalmente e submetidas a análise de conteúdo. Itens (trechos) identificados nos discursos e relacionados ao encaminhamento de pacientes com DPOC à RP e à prática de atividade física foram classificados como barreiras ou facilitadores. Tal classificação se baseou entre os quatorze domínios da Theoretical Domains Framework (TDF) e suas definições para identificar determinantes de comportamento entre os participantes relevantes para a mudança na prática clínica. Resultados: Setecentos e cinquenta e seis itens foram identificados nos discursos de vinte e um participantes e classificados como sendo barreiras (n= 279, 37%) ou facilitadores (n= 477, 63%) relacionados principalmente aos domínios da TDF de "Conhecimento" (n= 245, 32%), "Contexto e recursos ambientais" (n= 124, 16%) e "Papel e identidade social/profissional" (n= 107, 14%). Conclusão: As principais barreiras identificadas foram relacionadas aos programas de RP devido ao conhecimento restrito dos profissionais médicos sobre programas de RP, a disponibilidade reduzida de locais que oferecem estes programas e as dificuldades de acesso dos pacientes à RP. Os principais facilitadores identificados foram relacionados a orientação e o conhecimento pelos médicos sobre os benefícios da atividade física e a presença dos grupos de exercícios fornecidos na APS.
Introduction: Chronic obstructive pulmonary disease (COPD) has a high prevalence and entails high costs to health systems. Pulmonary rehabilitation (PR) is a non-pharmacological intervention that generates clinical benefits for patients and cost savings for the health system due to a reduced number of exacerbations and hospitalizations. Although strongly recommended, PR has been underutilized, with a low rate of indications. Objective: To identify barriers and facilitators for referring patients with COPD to PR and physical activity. Method: Qualitative study was carried out with medical staff working in primary health care using semi-structured interviews. The interviews were recorded, transcribed literally and underwent content analysis. Items (text excerpts) identified in the speeches and related to the referral of patients with COPD to PR and physical activity were classified according to as barriers or facilitators, and among the fourteen domains of the Theoretical Domains Framework (TDF) and its definitions; aiming to identify the determinants of behaviour which were relevant to change in clinical practice. Results: Seven hundred and fifty-six items were identified in the speeches of twenty-one participants and classified as barriers (n= 279, 37%) or facilitators (n= 477, 63%) mainly related to the TDF domains of "Knowledge" (n= 245, 32%), "Context and environmental resources" (n=124, 16%) and "Role and social/professional identity" (n= 107, 14%). Conclusion: The main barriers identified were related to referring patients PR due to lack of knowledge by medical staff about PR programs, the limited number of programs available, and the restricted access to PR program locations. The main facilitators were related to physical activity, mainly the medical staff's knowledge on physical activity benefits and availability of exercise group activities delivered at primary health care centres.
