Is the p-value properly interpreted by critical care professionals? Online survey. / O valor de p é adequadamente interpretado pelos profissionais de terapia intensiva? Uma pesquisa on-line.

OBJECTIVE: To determine the prevalence of and risk factors for insufficient knowledge related to p-values among critical care physicians and respiratory therapists in Argentina. METHODS: This cross-sectional online survey contained 25 questions about respondents' characteristics, self-perception and p-value knowledge (theory and practice). Descriptive and multivariable logistic regression analyses were conducted. RESULTS: Three hundred seventy-six respondents were analyzed. Two hundred thirty-seven respondents (63.1%) did not know about p-values. According to the multivariable logistic regression analysis, a lack of training on scientific research methodology (adjusted OR 2.50; 95%CI 1.37 - 4.53; p = 0.003) and the amount of reading (< 6 scientific articles per year; adjusted OR 3.27; 95%CI 1.67 - 6.40; p = 0.001) were found to be independently associated with the respondents' lack of p-value knowledge. CONCLUSION: The prevalence of insufficient knowledge regarding p-values among critical care physicians and respiratory therapists in Argentina was 63%. A lack of training on scientific research methodology and the amount of reading (< 6 scientific articles per year) were found to be independently associated with the respondents' lack of p-value knowledge.

OBJETIVO: Determinar a prevalência e os fatores de risco para conhecimento insuficiente sobre valores de p entre médicos e terapeutas respiratórios atuantes em terapia intensiva na Argentina. MÉTODOS: Levantamento transversal on-line com 25 questões relativas às características dos participantes, autopercepção e conhecimento sobre valores de p (teoria e prática). Realizaram-se análises de estatística descritiva e regressão logística multivariada. RESULTADOS: Analisaram-se 376 participantes. Não tinham conhecimento a respeito dos valores de p 237 participantes (63,1%). Segundo análise de regressão logística multivariada, falta de treinamento em metodologia científica (RC ajustadas 2,50; IC95% 1,37 - 4,53; p = 0,003) e a quantidade de leitura (< 6 artigos científicos por ano; RC ajustadas 3,27; IC95% 1,67 - 6,40; p = 0,001) foram identificados como independentemente associados com a falta de conhecimento sobre valores de p por parte dos participantes. CONCLUSÃO: A prevalência de conhecimento insuficiente com relação a valores de p entre médicos e terapeutas respiratórios na Argentina foi de 63%. Falta de treinamento em metodologia científica e quantidade de leitura (< 6 artigos científicos por ano) foram identificados como independentemente associados com a falta de conhecimento sobre valores de p por parte dos participantes.

Correlation between timed up and go, usual gait speed and dizziness handicap inventory in elderly with vestibular disorders: a retrospective and analytical study.

BACKGROUND: This study was done to verify the associations between the usual gait speed (UGS), the Timed Up and Go test (TUG), and the perception of disability in elderly vestibular patients and to identify factors associated with TUG results. METHODS: This was a descriptive, analytical, and retrospective study that used data from the clinical records of vestibular patients aged 65 years or older at a rehabilitation service in Buenos Aires, Argentina. The records were examined for the following information: sex, age, type of vestibular disorder, dizziness handicap inventory (DHI) score and performance in the TUG and UGS tests before treatment. Pearson's or Spearman's correlation coefficient was used depending on the distribution of data. Age and the DHI were factored into multiple linear regression models in order to model the tests. A Receiver Operating Characteristic (ROC) curve was used to analyze the predictive power of age, the DHI total, and the UGS for the sample's TUG results. The level of significance was 5%. RESULTS: We evaluated 118 clinical records, of which 26 were excluded due to incomplete information, leaving data from 92 vestibular patients (73 females; 78.3 ± 5.8 years old). Unilateral vestibular hypofunction and Benign Paroxysmal Positional Vertigo presented the highest prevalence. The total score and the DHI domains showed a significant association with the TUG and UGS values. The age-adjusted DHI had a low predictive power for these same values. CONCLUSIONS: The total score and DHI domains have a significant association with the TUG and UGS values for elderly adults with vestibular disorders. The age-adjusted DHI has a low predictive power for TUG and UGS values.

Patient-Reported and Performance Outcomes Significantly Improved in Elderly Patients with Vestibular Impairment following Rehabilitation: A Retrospective Study.

OBJECTIVE: To describe the results of a vestibular rehabilitation (VR) program in the timed up and go (TUG), gait speed (GS), and dizziness handicap inventory (DHI) scores for elderly vestibular patients in a developing country. METHODS: Descriptive study with retrospective data collected from the clinical records of vestibular patients. The following information was recorded: sex, age, type of vestibular disorder, DHI score, and performance in TUG and GS, before and after participation in a VR program taking place from January 1 to August 30, 2017. The VR program consisted of 10 twice weekly sessions in the clinic and daily exercises at the patient's home. We used Student's t-test for paired and Wilcoxon's test according to the data distribution. The level of significance was 5%. RESULTS: Data from 57 patients (49 females; 78 ± 5.8 years old) were used. There were statistically significant differences in TUG (12.52 versus 11.56), GS (0.81 versus 0.90 m/s), DHI total handicap (46 versus 24), physical (14 versus 8), emotional (14 versus 6), and functional (18 versus 12) domains. CONCLUSION: The functional outcome measures reported, including TUG, gait speed, and DHI, reflect statistically significant improvements in elderly patients after vestibular rehabilitation; the DHI improvements are clinically relevant.
