RESUMO
Purpose: Statistical literacy is the ability of a patient to apply basic statistical concepts to their health care. Understanding statistics is a critical component of shared decision making. The purpose of this investigation was to define levels of statistical literacy in an upper-extremity (UE) patient population. We aimed to determine if patient demographics would be associated with statistical literacy. Methods: An electronic survey was administered to a consecutive series of UE patients at a single institution. We recorded baseline demographics, Single Assessment Numeric Evaluation scores, the Berlin Numeracy Test (BNT), and General Health Numeracy Test. We also included a surgical risk question, which asked: "Approximately 3% of patients who get carpal tunnel surgery develop an infection. If 100 patients get this surgery, how many would you expect to develop an infection?" A covariate-controlled adjusted odds ratio reflecting the association between each statistical literacy outcome measure and patient characteristics was reported. Results: A total 254 surveys were administered, 148 of which were completed and included. Fifty percent of respondents had a high-school education or less. For the BNT, 78% scored in the bottom quartile, and 52% incorrectly answered all questions. For the General Health Numeracy Test, 34% answered 0 or 1/6 questions correctly. For the surgical risk question, 24% of respondents answered incorrectly. Respondents who had a college or graduate degree had 2.62 times greater odds (95% confidence interval, 1.09-6.32) of achieving a BNT score in a higher quartile than patients who did not have a college or graduate degree. Conclusions: Overall levels of statistical literacy are low for UE patients. Clinical relevance: When engaging in management discussions and shared decision making, UE surgeons should assume low levels of statistical literacy. Consideration of alternative formats, such as frequencies, video-based materials, and pictographs, may be warranted when discussing outcomes and risks of surgical procedures.
RESUMO
Pacientes com diabetes mellitus requerem um autocuidado extenso, com tratamentos complexos e comportamentos de saúde adequados, sendo, essas habilidades, fator chave. Frente a tal complexidade surge a importância do letramento funcional em saúde. O objetivo do estudo foi analisar fatores associados ao letramento em saúde e sua relação com controle glicêmico em pacientes diabéticos. Este estudo foi realizado com 82 pacientes diabéticos tipo 2, atendidos em um ambulatório de endocrinologia de um hospital público, de ambos os sexos e com idade entre 19 e 59 anos, que responderam à versão abreviada e traduzida do Test of Functional Health Literacy in Adults (b-TOFHLA). Valores de glicemia de jejum e hemoglobina glicada foram coletados dos prontuários dos participantes. Foram realizadas correlações, comparações de médias e modelos de regressão linear. O letramento inadequado foi encontrado em 65,9% dos pacientes. Foram fatores associados à pontuação do b-TOFHLA, a idade e os anos de estudos. O letramento global não explicou o controle glicêmico, mas o numeramento apresentou associação com tal controle. Nossos resultados apontam para a necessidade de melhorar o numeramento em saúde dos pacientes para obter seu melhor controle glicêmico, principalmente naqueles com maior idade e menos anos de estudo.
Diabetes mellitus patients must concentrate on self-care, with complex treatments and adequate health behavior in which such habits are a key factor. Due to the complexity of this issue, the importance of literacy in health arises. The goal of the study was to analyze factors associated with literacy in health and its relation with glycemic control in diabetic patients. It involved a study with 82 type 2 diabetic patients of both sexes and aged between 19 and 59 attended in the outpatient endocrinology ward of a public hospital, who filled out an abbreviated and translated version of the Test of Functional Health Literacy in Adults (b-TOFHLA). Fasting glycaemia values and glycated hemoglobin were collected from the clinical history of the participants. Correlations, mean comparisons and linear regression models were tested. Inadequate literacy in health was encountered in 65.9% of the patients. The issues involved factors associated with the b-TOFHLA point scores were age and years of schooling. Global literacy did not explain the glycemic control, but the level of numeracy presented an association with this control. The results point to the need to improve the numeracy in health of the patients to obtain enhanced glycemic control, mainly in those with more advanced age and less years of schooling.
