Resumo
Introdução: A fase avançada de pneumopatias, cardiopatias e doenças sistêmicas está associada com o desenvolvimento de insuficiência respiratória crônica (IRespC). O tratamento desta complicação inclui o uso de oxigenoterapia domiciliar prolongada. Na literatura nacional poucos estudos avaliaram a sobrevida em pacientes com doença pulmonar obstrutiva crônica (DPOC) ou com IRespC recebendo oxigenoterapia domiciliar prolongada (ODP). Objetivo: O objetivo deste estudo foi avaliar os fatores de predição de mortalidade em pacientes com IRespC tratados com ODP no período de um, dois e três anos. Pacientes e Métodos: Foram avaliados e acompanhados pelo período mínimo de três anos ou até o óbito, 142 pacientes cadastrados no ambulatório de oxigenoterapia da Faculdade de Medicina de Botucatu (FMB) até julho de 2005. Na avaliação inicial, foram coletados dados de identificação pessoal, história de tabagismo, o uso de medicação, composição corporal, força de preensão manual, função pulmonar, gases sanguíneos e hemograma. Também foram aplicados a escala de dispnéia de Borg, o índice de dispnéia basal (BDI) e o questionário de qualidade de vida na doença respiratória do Hospital Saint George (SGRQ). Resultados: Durante os três anos de estudo; 83 pacientes (58%) morreram: 37 (26%) durante o primeiro ano de acompanhamento, 23 (16%) no segundo ano e 23 (16%) no período de três anos. O grupo óbito apresentou valores de hematócrito e hemoglobina significativamente menores, maior sensação de dispnéia, avaliada pelo BDI e Borg, e apresentou maior 18 comprometimento do estado de saúde, avaliado pelos domínios, impacto, atividade e total do SGRQ. Os principais preditores de mortalidade, na avaliação que incluía todos os pacientes, no período de três anos foram: gênero masculino (HR=2,67, CI=1,15-6,18, p=0,02), menores valores de hemoglobina...
Introduction: The advanced stage of lung, heart and systemic diseases is associated with the development of chronic respiratory failure (CRF). The treatment of this complication includes the use of long term oxygen therapy (LTOT). In the national literature few studies have assessed the survival of patients with chronic obstructive pulmonary disease (COPD) or with chronic respiratory failure treated with LTOT. Aim: The aim of this study was to evaluate the predictors of mortality in patients with CRF treated with oxygen in the period of one, two and three years. Patients and Methods: One hundred forty two patients were evaluated and followed for the minimum period of three years or until death. The study group consisted of patients with CRF, clinically stable, seen at the Oxygen Therapy Outpatient Clinic of Botucatu School of Medicine Hospital. Information about the demographic characteristics, smoking history, comorbidity conditions and treatment were collected during the first visit; evaluation of body composition, handgrip strength, lung function and blood gases and blood counts were also undertaken at this time. In addition, the dyspnea sensation (basal dyspnea index - BDI - and Borg scale) and health related quality of life (Saint George Respiratory Questionnaire) scores were calculated. Results: During the follow-up, 83 (58%) patients died; 37 (26%) during the first year of follow-up, 23 (16%) in the second year and 23 (16%) considering in three years. The group of death showed significantly lower 20 hematocrit and hemoglobin, increased sensation of breathlessness, measured by BDI and Borg, and showed greater impairment of health status as measured by impact, activity and total score of SGRQ. The main predictors of mortality, after three years of follow-up were male gender (HR=2.67, CI=1.15-6.18, p=0.02), lower values of hemoglobin (HR=0.85, CI=0.74-0.98, p=0.02), and PaCO2...
