RESUMO

There is an urgent need for consensus on what defines a chronic obstructive pulmonary disease (COPD) self-management intervention. We aimed to obtain consensus regarding the conceptual definition of a COPD self-management intervention by engaging an international panel of COPD self-management experts using Delphi technique features and an additional group meeting.In each consensus round the experts were asked to provide feedback on the proposed definition and to score their level of agreement (1=totally disagree; 5=totally agree). The information provided was used to modify the definition for the next consensus round. Thematic analysis was used for free text responses and descriptive statistics were used for agreement scores.In total, 28 experts participated. The consensus round response rate varied randomly over the five rounds (ranging from 48% (n=13) to 85% (n=23)), and mean definition agreement scores increased from 3.8 (round 1) to 4.8 (round 5) with an increasing percentage of experts allocating the highest score of 5 (round 1: 14% (n=3); round 5: 83% (n=19)).In this study we reached consensus regarding a conceptual definition of what should be a COPD self-management intervention, clarifying the requisites for such an intervention. Operationalisation of this conceptual definition in the near future will be an essential next step.

RESUMO

BACKGROUND: The data on cost savings with disease management (DM) in chronic obstructive pulmonary disease (COPD) is limited. A multicomponent DM program in COPD has recently shown in a large randomized controlled trial to reduce hospitalizations and emergency department visits compared to usual care (UC). The objectives of this study were to determine the cost of implementing the DM program and its impact on healthcare resource utilization costs compared to UC in high-risk COPD patients. MATERIALS AND METHODS: This study was a post-hoc economic analysis of a multicenter randomized, adjudicator-blinded, controlled, 1-year trial comparing DM and UC at 5 Midwest region Department of Veterans Affairs (VA) medical centers. Health-care costs (hospitalizations, ED visits, respiratory medications, and the cost of the DM intervention) were compared in the COPD DM intervention and UC groups. RESULTS: The composite outcome for all hospitalizations or ED visits were 27% lower in the DM group (123.8 mean events per 100 patient-years) compared to the UC group (170.5 mean events per 100 patient-years) (rate ratio 0.73; 0.56-0.90; p < 0.003). The cost of the DM intervention was $241,620 or $650 per patient. The total mean ± SD per patient cost that included the cost of DM in the DM group was 4491 ± 4678 compared to $5084 ± 5060 representing a $593 per patient cost savings for the DM program. CONCLUSIONS: The DM intervention program in this study was unique for producing an average cost savings of $593 per patient after paying for the cost of DM intervention.

RESUMO

Deep venous thrombosis and pulmonary embolism are associated with approximately 250,000 hospitalizations each year. Nearly seventy percent of patients who die of a pulmonary embolism do so within the first hour after onset of symptoms, so prompt and appropriate treatment is needed. Pulmonary embolectomy is a viable alternative for massive and submassive pulmonary embolism. We report 3 cases of successful pulmonary embolectomy.

RESUMO

Although noninvasive ventilation (NIV) has been used since the 1950s in the polio epidemic, the development of modern bilevel positive airway pressure (BPAP) devices did not become a reality until the 1990s. Over the past 25 years, BPAP technology options have increased exponentially. The number of patients receiving this treatment both in the acute setting and at home is growing steadily. However, a knowledge gap exists in the way the settings on these devices are adjusted to achieve synchrony and match the patient's unique physiology of respiratory failure. This issue is further complicated by differences in pressure and flow dynamic settings among different types of NIV devices available for inpatient and home care.

RESUMO

OSA is a common chronic disorder that is associated with significant morbidity and mortality including cardiovascular, metabolic, and neurocognitive disease and increased cancer-related deaths. OSA is characterized by recurrent episodes of apneas and hypopneas associated with repetitive episodes of intermittent hypoxemia, intrathoracic pressure changes, and arousals. Intermittent hypoxemia (IH) is now being recognized as a potential major factor contributing to the pathogenesis of OSA-related comorbidities. OSA-related high-frequency IH is characterized by cycles of hypoxemia with reoxygenation that is distinctly different than sustained low-frequency hypoxia and contributes to ischemia-reperfusion injury. Data from both animal and human studies support mechanistic links between IH and its adverse impact at the tissue level. IH promotes oxidative stress by increased production of reactive oxygen species and angiogenesis, increased sympathetic activation with BP elevation, and systemic and vascular inflammation with endothelial dysfunction that contributes to diverse multiorgan chronic morbidity and mortality affecting cardiovascular disease, metabolic dysfunction, cognitive decline, and progression of cancer. Data from observational studies in large population groups also support the role for hypoxia in the pathogenesis of OSA comorbidity. Treatment with CPAP to reverse OSA-related symptoms and comorbidities has been shown to provide variable benefit in some but not all patient groups. Early treatment with CPAP makes intuitive sense to promote maximal functional recovery and minimize residual injury. More studies are needed to determine the interacting effects of IH and obesity, differential effects of both short-term and long-term hypoxemia, and the effect of CPAP treatment.

RESUMO

BACKGROUND: Most interventions aimed at reducing hospitalizations and emergency department (ED) visits in patients with chronic obstructive pulmonary disease (COPD) have employed resource-intense programs in high-risk individuals. Although COPD is a progressive disease, little is known about the effectiveness of proactive interventions aimed at preventing hospitalizations and ED visits in the much larger population of low-risk (no known COPD-related hospitalizations or ED visits in the prior year) patients, some of whom will eventually become high-risk. METHODS: We tested the effect of a simple educational and self-efficacy intervention (n = 2243) versus usual care (n = 2182) on COPD/breathing-related ED visits and hospitalizations in a randomized study of low-risk patients at three Veterans Affairs (VA) medical centers in the upper Midwest. Administrative data was used to track VA admissions and ED visits. A patient survey was used to determine health-related events outside the VA. RESULTS: Rates of COPD-related VA hospitalizations in the education and usual care group were not significantly different (3.4 versus 3.6 admissions per 100 person-years, respectively; 95% CI of difference -1.3 to 1.0, P = 0.77). The much higher patient-reported rates of non-VA hospitalizations for breathing-related problems were lower in the education group (14.0 versus 19.0 per 100 person-years; 95% CI -8.6 to -1.4, P = 0.006). Rates of COPD-related VA ED visits were not significantly different (6.8 versus 5.3; 95% CI -0.1 to 3.0, P = 0.07), nor were non-VA ED visits (32.4 versus 36.5; 95% CI -9.3 to 1.1, P = 0.12). All-cause VA admission and ED rates did not differ. Mortality rates (6.9 versus 8.3 per 100 person-years, respectively; 95% CI -3.0 to 0.4, P = 0.13) did not differ. CONCLUSION: An educational intervention that is practical for large numbers of low-risk patients with COPD may reduce the rate of breathing-related hospitalizations. Further research that more closely tracks hospitalizations to non-VA facilities is needed to confirm this finding.
