Relação entre a magnitude de sintomas e a qualidade de vida: análise de agrupamentos de pacientes com câncer de pulmão no Brasil

OBJECTIVE: Lung cancer patients often experience profound physical and psychosocial changes as a result of disease progression or treatment side effects. Fatigue, pain, dyspnea, depression, and sleep disturbances appear to be the most common symptoms in such patients. The objective of the present study was to examine the prevalence of symptoms in lung cancer patients in order to identify subgroups (clusters) of patients, grouped according to the magnitude of the symptoms, as well as to compare the quality of life among the identified subgroups. METHODS: A cross-sectional study involving agglomerative hierarchical clustering. A total of 50 lung cancer patients were evaluated in terms of their demographic characteristics and their scores on three quality of life questionnaires, namely the 30-item European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30), the Functional Assessment of Cancer Therapy-Lung, and the Medical Outcomes Study 36-item Short-form Survey. The cluster analysis took into account the magnitude of the most prevalent symptoms as assessed by the EORTC QLQ-C30 symptom scale scores; those symptoms were fatigue, pain, dyspnea, and insomnia. RESULTS: Three clusters (subgroups)_of patients were identified on the basis of the magnitude of the four most prevalent symptoms. The three subgroups of patients were as follows: patients with mild symptoms (n = 30; 60%); patients with moderate symptoms (n = 14; 28%); and patients with severe symptoms (n = 6; 12%). The subgroup of patients with severe symptoms had the worst quality of life, as assessed by the total scores and by the integrated domains of all three instruments. CONCLUSIONS: This study highlights the importance of symptom cluster assessment as an important tool to assess the quality of life of patients with chronic diseases, such as lung cancer.OBJETIVO: Muitas vezes pacientes com câncer de pulmão vivenciam mudanças físicas e psicossociais profundas que resultam da progressão da doença ou dos efeitos colaterais do tratamento. Fadiga, dor, dispneia, depressão e distúrbios do sono parecem ser os sintomas mais comuns nesses pacientes. O objetivo deste estudo foi examinar a prevalência de sintomas em pacientes com câncer de pulmão a fim de identificar subgrupos (clusters) de pacientes, agrupados de acordo com a magnitude dos sintomas, bem como comparar os subgrupos quanto à qualidade de vida. MÉTODOS: Estudo transversal utilizando agrupamento hierárquico aglomerativo. Foram avaliadas as características demográficas de 50 pacientes com câncer de pulmão, bem como sua pontuação em três questionários de qualidade de vida: o 30-item European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30), o Functional Assessment of Cancer Therapy-Lung e o Medical Outcomes Study 36-item Short-form Survey. A análise de agrupamentos (clusters) levou em conta a magnitude dos sintomas de maior prevalência de acordo com as escalas de sintomas do EORTC QLQC-30; esses sintomas foram fadiga, dor, dispneia e insônia. RESULTADOS: Foram identificados três agrupamentos (subgrupos) de pacientes, baseados na magnitude dos quatro sintomas mais prevalentes. Os três subgrupos de pacientes foram os seguintes: pacientes com sintomas leves (n = 30; 60%); pacientes com sintomas moderados (n = 14; 28%) e pacientes com sintomas graves (n = 6; 12%). O subgrupo de pacientes com sintomas graves apresentou a pior qualidade de vida, conforme mensurada pelos escores totais e pelas dimensões integradas dos três instrumentos. CONCLUSÕES: Este estudo destaca a importância da avaliação de agrupamentos de sintomas como uma ferramenta relevante para medir a qualidade de vida de pacientes com doenças crônicas, como o câncer de pulmão.Universidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

METHODS: Twenty-nine patients from a rehabilitation center were assessed with the ICF Core Set for low back pain, Roland Morris Questionnaire (RMQ) and SF-36. RESULTS: All Body structures categories of this ICF Core Set were impaired in at least 80% of the patients, thus they were considered validated. Among the 19 Body functions categories, only four were impaired in less than 80%, thus not-validated, the same was observed in five out of the 29 Activities and participation categories and five of the 25 Environmental factors categories. CONCLUSIONS: The selected categories of the ICF Core Set for low back pain were empirically validated, and together, they allowed the description of functioning of those patients. This ICF Core Set can be used to guide interdisciplinary therapeutic interventions

Distance between residence and the dialysis unit does not impact self-perceived outcomes in hemodialysis patients

<p>Abstract</p> <p>Background</p> <p>Patients have to travel long distances to undergo hemodialysis (HD) in some regions. We aimed to search for an association of the distance between patients’ residence and the dialysis unit with quality of life, depression and coping among end-stage renal disease (ESRD) patients undergoing maintenance HD.</p> <p>Methods</p> <p>We studied 161 ESRD patients undergoing HD during April 2009. Quality of life, depression and coping were assessed by the SF-36, the 10-item CES-D and the Jalowiec Coping Scale, respectively. The sample was stratified in three groups: I-patients residing in Sobral (where the dialysis unit is located); II-patients residing in towns up to 100 km from Sobral; and III-patients residing in towns distant greater than 100 km from Sobral. Analysis of variance was used to detect differences in quality of life and coping scores between the groups. Logistic regression was used to test distance as a predictor of depression.</p> <p>Results</p> <p>There were 47 (29.2%) patients residing in Sobral, 46 (28.6%) up to 100 km away and 68 (42.2%) greater than 100 km from Sobral. There were no differences related to quality of life and coping scores between the groups. Distance was not a predictor of depression.</p> <p>Conclusions</p> <p>Social and cultural factors may explain the lack of differences. Studies from other regions are needed to clarify the distance effects on self-perceived outcomes among HD patients.</p

Family caregiver burden: the burden of caring for lung cancer patients according to the cancer stage and patient quality of life

ABSTRACT Objective: Patients with lung cancer experience different feelings and reactions, based on their family, social, cultural, and religious backgrounds, which are a source of great distress, not only for the patients but also for their family caregivers. This study aimed to evaluate the impact that lung cancer stage and quality of life (QoL) of lung cancer patients have on caregiver burden. Methods: This was a prospective cross-sectional study. Consecutive patient-caregiver dyads were selected and asked to complete the Hospital Anxiety and Depression Scale and the Medical Outcomes Study 36-item ShortForm Health Survey (SF-36). Family caregivers also completed the Caregiver Burden Scale. Group-based modeling was used in order to identify patients with early- or advanced-stage cancer (IA to IIIA vs. IIIB to IV) plus non-impaired or impaired QoL (SF36 total score > 50 vs. &#8804; 50). Patient-caregiver dyads were stratified into four groups: early-stage cancer+non-impaired QoL; advanced-stage cancer+non-impaired QoL; early-stage cancer+impaired QoL; and advanced-stage cancer+impaired QoL. Results: We included 91 patient-caregiver dyads. The majority of the patients were male and heavy smokers. Family caregivers were younger and predominantly female. The burden, QoL, level of anxiety, and level of depression of caregivers were more affected by the QoL of the patients than by their lung cancer stage. The family caregivers of the patients with impaired QoL showed a higher median burden than did those of the patients with non-impaired QoL, regardless of disease stage. Conclusions: Caregiver burden is more affected by patient QoL than by lung cancer stage

Depression and quality of life of hemodialysis patients living in a poor region of Brazil Depressão e qualidade de vida entre pacientes em hemodiálise de uma região pobre do Brasil

OBJECTIVE: To determine the correlation between depression and quality of life (QOL) of patients in hemodialysis (HD). METHOD: One hundred and sixty six patients over 18 years of age who had been in HD for at least three months and had no history of transplant. QOL was assessed using the SF-36. To categorize depression, a score > 10 was used on the 10-item version of the Center for Epidemiologic Studies Depression Scale (CES-D). Comparisons between depressed and nondepressed patients were performed using the chi-square test, Student's t-test, and Mann-Whitney test. Multiple regression was performed to assess the predictive variables of patients' QOL. RESULTS: Symptoms of depression were found in 13 (7.8%) patients. The only variable that differed among depressed patients was QOL. Depressed patients presented lower scores in vitality (40.7 vs. 57.3; p = 0.010), role-emotional (25.6 vs. 62.5; p = 0.006), and mental health (50.1 vs. 65.4; p = 0.023). Regression analysis demonstrated that depression was a predictor of role-emotional (OR = 0.981, CI = 0.967-0.996; p = 0.010) and mental health (OR = 0.970, CI = 0.946-0.996; p = 0.022). CONCLUSION: Depressed patients experience a poor QOL because, in addition to their chronically affected physical aspects, they also feel limited in the mental dimensions, which usually have the highest score among non-depressed HD patients.<br>OBJETIVO: Determinar a correlação entre depressão e qualidade de vida (QV) de pacientes submetidos à hemodiálise (HD). MÉTODO: Foram estudados 166 pacientes com idade superior a 18 anos, em HD por pelo menos três meses e sem transplante prévio. O nível de QV foi medido pelo questionário SF-36. Para categorizar depressão foi utilizada a versão de 10 itens do Center for Epidemiologic Studies Depression Scale (CES-D; escore > 10). As comparações entre pacientes com e sem depressão foram realizadas pelos testes do qui-quadrado, t de Student e Mann-Whitney. Regressão múltipla foi realizada para testar variáveis preditivas de QV. RESULTADOS: Sintomas depressivos estavam presentes em 13 (7,8%) pacientes. A única variável que diferiu entre os pacientes com depressão foi QV. Pacientes depressivos apresentaram menor pontuação referente a vitalidade (40,7 vs. 57,3; p = 0,010), aspectos emocionais (25,6 vs. 62,5; p = 0,006) e saúde mental (50,1 vs. 65,4; p = 0,023). A análise de regressão demonstrou que depressão foi preditiva de aspectos emocionais (OR = 0,981, IC = 0,967-0,996; p = 0,010) e de saúde mental (OR = 0,970, CI = 0,946-0,996; p = 0,022). CONCLUSÃO: Pacientes com depressão vivenciam um nível baixo de QV porque, além dos aspectos físicos afetados cronicamente, esses pacientes são afetados nas dimensões mentais que costumam ser as dimensões com melhores pontuações entre os pacientes em HD sem depressão
