A qualitative study of patients' goals and expectations for self-management of COPD.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is an illness that affects patients on multiple levels, both physically and psychologically. While there is a growing body of evidence for the efficacy of self-management among patients with COPD, little evidence is available on the optimal content and methods for delivering self-management support. AIMS: The purpose of this study was to address gaps in the literature on self-management support by examining patients' responses to questions about goals, needs, and expectations regarding self-management using qualitative methods in a broadly representative sample of patients with moderate to severe COPD. By focusing on patients' perceptions of their needs, we hoped to guide development of cognitive-behavioural interventions for self-management support. METHODS: Patients >45 years of age with a physician diagnosis of COPD were recruited as part of a larger randomised controlled trial designed to determine the effectiveness of a lifestyle behavioural intervention to increase physical activity. In-depth interviews were conducted at baseline data collection using 10 standardised open-ended questions tailored to examine factors relevant to self-management support including concerns, fears, learning needs, barriers, facilitators, and goals. All interviews were audio recorded and analysed using qualitative methods. Responses were coded by three raters into thematic categories. RESULTS: A sample of 47 interviews with patients of mean age 68.4 years, 53% male, 87% white were used in the analysis. The distribution of spirometric impairment based on percent predicted forced expiratory volume in 1 second (FEV1) was moderate (57.5%), severe (31.9%), and very severe (10.6%). In response to questions targeting needs and goals for care, three main themes (loss, fear, and desire for improved care) and seven associated sub-themes were identified. Because of breathlessness and fatigue as well as symptoms from conditions other than COPD, patients reported the loss of ability to participate in pleasurable and necessary activities of daily living and the desire to recover at least some of their functioning. They expressed problems with social isolation and uncertainty about their prognosis, as well as the hope to improve. In addition, fearful experiences associated with uncontrolled breathlessness and a wish for greater understanding and knowledge about treatment were major concerns. CONCLUSIONS: These qualitative results suggest that the content of self-management support for patients with COPD should focus on addressing patients' fears associated with the uncertainty, progression, and suffering of their disease, their expectations about overcoming or replacing losses, their needs for improved health literacy and their desire for improved care. These responses indicate areas where cognitive-behavioural intervention should focus in order to enhance patient self-efficacy, motivation, and behavioural change for improved self-management.

Ground-level falls: 9-year cumulative experience in a regionalized trauma system.

Ground-level falls (GLFs) are the leading cause of nonfatal hospitalized injuries in the US. We hypothesized that risk-adjusted mortality would not vary between levels of trauma center verification if regional triage functioned appropriately. Data were collected from our regional trauma registry for the years 2001 through 2009. A multilevel mixed-effects logistic regression model was developed to compare risk-adjusted mortality rates by trauma center level and by year. GLF patients numbered 8202 over 9 years with 2.1% mortality. Mean age was 74.5 years and mean probability of death was 0.021 (95% confidence interval [CI], 0.020-0.021). The level I center-treated patients had the highest probability of death (0.033) compared to levels II and III/IV patients (0.023 and 0.018, respectively; P < 0.001), with the highest mortality (6.0%, 3.1%, and 1.1% for levels I, II, and III/IV; P < 0.001). The adjusted odds ratio of mortality was lowest at the level I center (0.71; 95% CI, 0.56-0.91), while no difference existed between level II (1.17; 95% CI, 0.90-1.51) and level III/IV centers (1.22; 95% CI, 0.90-1.66). The 95% CIs for risk-adjusted mortality by year overlapped the 1.0 reference line for each year from 2002 to 2009. In conclusion, regional risk-adjusted mortality for GLF has varied little since 2002. More study is warranted to understand the lower risk-adjusted GLF mortality at the level I center for this growing patient population.

An RGS-containing sorting nexin controls Drosophila lifespan.

The pursuit of eternal youth has existed for centuries and recent data indicate that fat-storing tissues control lifespan. In a D. melanogaster fat body insertional mutagenic enhancer trap screen designed to isolate genes that control longevity, we identified a regulator of G protein signaling (RGS) domain containing sorting nexin, termed snazarus (sorting nexin lazarus, snz). Flies with insertions into the 5' UTR of snz live up to twice as long as controls. Transgenic expression of UAS-Snz from the snz Gal4 enhancer trap insertion, active in fat metabolic tissues, rescued lifespan extension. Further, the lifespan extension of snz mutants was independent of endosymbiont, e.g., Wolbachia, effects. Notably, old snz mutant flies remain active and fertile indicating that snz mutants have prolonged youthfulness, a goal of aging research. Since mammals have snz-related genes, it is possible that the functions of the snz family may be conserved to humans.
