ABSTRACT

Childhood, adolescent, and young adult (CAYA) cancer survivors are at risk of developing late effects associated with their cancer and its treatment. Survivors' engagement with recommended follow-up care to minimize these risks is suboptimal, with many barriers commonly reported. This scoping review aims to summarize the barriers to accessing follow-up care, using the dimensions of Levesque's framework for accessing healthcare. We retrieved quantitative studies addressing barriers and facilitators to accessing survivorship care in CAYA survivors from PubMed, EMBASE and CINAHL. Data was categorized into the five healthcare access dimensions outlined in Levesque's framework: i) approachability, ii) acceptability, iii) availability and accommodation, iv) affordability, and v) appropriateness. We identified 27 quantitative studies in our review. Commonly reported barriers to accessing care included a lack of survivor and provider knowledge of cancer survivorship, poor health beliefs, low personal salience to engage in follow-up care, high out-of-pocket costs and survivors living long distances from clinical services. Many studies reported increased barriers to care during the transition from paediatric to adult-oriented healthcare services, including a lack of developmentally appropriate services, lack of appointment reminders, and a poorly defined transition process. Healthcare-related self-efficacy was identified as an important facilitator to accessing follow-up care. The transition from pediatric to adult-oriented healthcare services is a challenging time for childhood, adolescent, and young adult cancer survivors. Optimizing CAYAs' ability to access high-quality survivorship care thus requires careful consideration of the quality and acceptability of services, alongside financial and physical/practical barriers (eg distance from available services, appointment-booking mechanisms). Levesque's model highlighted several areas where evidence is well established (eg financial barriers) or lacking (eg factors associated with engagement in follow-up care) which are useful to understand barriers and facilitators that impact access to survivorship for CAYA cancer survivors, as well as guiding areas for further evaluation.

ABSTRACT

Chemokines and chemokine receptors have been implicated in the pathogenesis of bronchiolitis. CXCR3 ligands (CXCL10, CXCL9, and CXCL11) were elevated in patients with bronchiolitis obliterans syndrome (BOS) and chronic allorejection. Studies also suggested that blockage of CXCR3 or its ligands changed the outcome of T-cell recruitment and airway obliteration. We wanted to determine the role of the chemokine CXCL10 in the pathogenesis of bronchiolitis and BOS. In this study, we found that CXCL10 mRNA levels were significantly increased in patients with BOS. We generated transgenic mice expressing a mouse CXCL10 cDNA under control of the rat CC10 promoter. Six-month-old CC10-CXCL10 transgenic mice developed bronchiolitis characterized by airway epithelial hyperplasia and developed peribronchiolar and perivascular lymphocyte infiltration. The airway hyperplasia and T-cell inflammation were dependent on the presence of CXCR3. Therefore, long-term exposure of the chemokine CXCL10 in the lung causes bronchiolitis-like inflammation in mice.

ABSTRACT

BACKGROUND: Growing numbers of critically ill patients receive prolonged mechanical ventilation. Little is known about the patterns of care as patients transition from acute care hospitals to postacute care facilities or about the associated resource utilization. OBJECTIVE: To describe 1-year trajectories of care and resource utilization for patients receiving prolonged mechanical ventilation. DESIGN: 1-year prospective cohort study. SETTING: 5 intensive care units at Duke University Medical Center, Durham, North Carolina. PARTICIPANTS: 126 patients receiving prolonged mechanical ventilation (defined as ventilation for >or=4 days with tracheostomy placement or ventilation for >or=21 days without tracheostomy), as well as their 126 surrogates and 54 intensive care unit physicians, enrolled consecutively over 1 year. MEASUREMENTS: Patients and surrogates were interviewed in the hospital, as well as 3 and 12 months after discharge, to determine patient survival, functional status, and facility type and duration of postdischarge care. Physicians were interviewed in the hospital to elicit prognoses. Institutional billing records were used to assign costs for acute care, outpatient care, and interfacility transportation. Medicare claims data were used to assign costs for postacute care. RESULTS: 103 (82%) hospital survivors had 457 separate transitions in postdischarge care location (median, 4 transitions [interquartile range, 3 to 5 transitions]), including 68 patients (67%) who were readmitted at least once. Patients spent an average of 74% (95% CI, 68% to 80%) of all days alive in a hospital or postacute care facility or receiving home health care. At 1 year, 11 patients (9%) had a good outcome (alive with no functional dependency), 33 (26%) had a fair outcome (alive with moderate dependency), and 82 (65%) had a poor outcome (either alive with complete functional dependency [4 patients; 21%] or dead [56 patients; 44%]). Patients with poor outcomes were older, had more comorbid conditions, and were more frequently discharged to a postacute care facility than patients with either fair or good outcomes (P < 0.05 for all). The mean cost per patient was $306,135 (SD, $285,467), and total cohort cost was $38.1 million, for an estimated $3.5 million per independently functioning survivor at 1 year. LIMITATION: The results of this single-center study may not be applicable to other centers. CONCLUSION: Patients receiving prolonged mechanical ventilation have multiple transitions of care, resulting in substantial health care costs and persistent, profound disability. The optimism of surrogate decision makers should be balanced by discussions of these outcomes when considering a course of prolonged life support. PRIMARY FUNDING SOURCE: None.

ABSTRACT

OBJECTIVE: To compare prolonged mechanical ventilation decision-makers' expectations for long-term patient outcomes with prospectively observed outcomes and to characterize important elements of the surrogate-physician interaction surrounding prolonged mechanical ventilation provision. Prolonged mechanical ventilation provision is increasing markedly despite poor patient outcomes. Misunderstanding prognosis in the prolonged mechanical ventilation decision-making process could provide an explanation for this phenomenon. DESIGN: Prospective observational cohort study. SETTING: Academic medical center. PATIENTS: A total of 126 patients receiving prolonged mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Participants were interviewed at the time of tracheostomy placement about their expectations for 1-yr patient survival, functional status, and quality of life. These expectations were then compared with observed 1-yr outcomes measured with validated questionnaires. The 1-yr follow-up was 100%, with the exception of patient death or cognitive inability to complete interviews. At 1 yr, only 11 patients (9%) were alive and independent of major functional status limitations. Most surrogates reported high baseline expectations for 1-yr patient survival (n = 117, 93%), functional status (n = 90, 71%), and quality of life (n = 105, 83%). In contrast, fewer physicians described high expectations for survival (n = 54, 43%), functional status (n = 7, 6%), and quality of life (n = 5, 4%). Surrogate-physician pair concordance in expectations was poor (all kappa = <0.08), as was their accuracy in outcome prediction (range = 23%-44%). Just 33 surrogates (26%) reported that physicians discussed what to expect for patients' likely future survival, general health, and caregiving needs. CONCLUSIONS: One-year patient outcomes for prolonged mechanical ventilation patients were significantly worse than expected by patients' surrogates and physicians. Lack of prognostication about outcomes, discordance between surrogates and physicians about potential outcomes, and surrogates' unreasonably optimistic expectations seem to be potentially modifiable deficiencies in surrogate-physician interactions.

ABSTRACT

High practice variability in critical care medicine contributes to medical errors and the high cost of ICU care. Clinical guidelines and protocol-based strategies can reduce the variation and cost of ICU medicine, increase adherence to evidence-based interventions, and reduce error, thereby improving the morbidity and mortality of critically ill patients. There are various barriers to guideline adherence, and protocols often are more successful when implemented by nonphysicians. However, this has potential consequences for house-staff knowledge and education. This article discusses the implications of mechanical ventilation protocols on patient care and medical education, and this article offers suggestions for synchronizing the processes for improving patient care to improve medical education.

ABSTRACT

BACKGROUND: Despite the frequent occurrence of pleural effusions in lung transplant recipients, little is known about early posttransplant pleural space infections. We sought to determine the predictors and clinical significance of pleural infection in this population. METHODS: We analyzed 455 consecutive lung transplant recipients and identified patients who had undergone sampling of pleural fluid within 90 days posttransplant. A case-control analysis was performed to determine the characteristics that predict infection and the impact of infection on posttransplant survival. RESULTS: Pleural effusions undergoing drainage occurred in 27% of recipients (124 of 455 recipients). Ninety-six percent of effusions were exudative. Pleural space infection occurred in 27% of patients (34 of 124 patients) with effusions. The incidence of infection did not differ significantly by native lung disease or type of transplant operation. Fungal pathogens accounted for > 60% of the infections; Candida albicans was the predominant organism found. Bacterial etiologies were present in 25% of cases. Infected pleural effusions had elevated lactate dehydrogenase levels (p = 0.036) and markedly increased neutrophil levels in the pleural space (p < 0.0001) compared to noninfected effusions. A pleural neutrophil percentage of > 21% provides a sensitivity of 70% and a specificity of 79% for correctly identifying an infection. Patients with pleural space infection had a diminished 1-year survival rate compared to those without infection (67% vs 87%, respectively; p = 0.002). CONCLUSION: Pleural infection with fungal or bacterial pathogens commonly complicates lung transplantation, and an elevated neutrophil level in the pleural fluid is the most sensitive and specific indicator of infection.
