Patients rate physician communication about lung cancer.

BACKGROUND: High-quality lung cancer care includes physician-patient communication about the disease and treatment, patient needs/preferences, and care goals. In this study, the authors evaluated communication with patients at all stages across multiple topics. METHODS: A standardized questionnaire asked patients with lung cancer to rate (on 5-point, verbal descriptor scale) the extent of communication with physicians on symptoms, spiritual concerns, practical needs, proxy appointment, living will preparation, prognosis, care goals, potential complications of therapy, life support preferences, and hospice. Communication was defined as inadequate if the patient reported discussing ≥5 of 11 questionnaire topics "not at all" or "a little bit." Multivariate logistic regression was used to evaluate the factors associated with inadequate communication. RESULTS: In total, 276 of 348 (79%) eligible patients were enrolled (mean age [±standard deviation], 65 ± 10 years; 55% white, 21% black, and 19% Hispanic; all disease stages). For most topics, the majority of respondents reported that physicians communicated "not at all" or "a little bit." Low ratings were frequent for discussion of emotional symptoms (56%; 95% confidence interval [CI], 49%-62%), practical needs (71%; 95% CI, 65%-76%), spiritual concerns (80%; 95% CI, 75%-85%), proxy appointment (63%; 95% CI, 57%-69%), living will preparation (90%; 95% CI, 85%-93%), life support preferences (80%; 95% CI, 75%-84%), and hospice (88%; 95% CI, 86%-94%). Communication was inadequate for patients of different ages, stages, and races, although Hispanics were less likely than non-Hispanic whites and blacks to report inadequate communication (odds ratio, 0.31; 95% CI, 0.15-0.65). CONCLUSIONS: Across all stages, patients with lung cancer reported low rates of physician-patient communication on key topics, which may increase patient distress, impair decision-making, and compromise clinical outcomes and use patterns.

Targeted Phage Display-based Pulmonary Vaccination in Mice and Non-human Primates.

BACKGROUND: The extensive alveolar capillary network of the lungs is an attractive route for administration of several agents. One key functional attribute is the rapid onset of systemic action due to the absence of first-pass metabolism. METHODS: Here we applied a combinatorial approach for ligand-directed pulmonary delivery as a unique route for systemic targeting in vaccination. FINDINGS: We screened a phage display random peptide library in vivo to select, identify, and validate a ligand (CAKSMGDIVC) that specifically targets and is internalized through its receptor, α3ß1 integrin, on the surface of cells lining the lung airways and alveoli and mediates CAKSMGDIVC-displaying phage binding and systemic delivery without compromising lung homeostasis. As a proof-of-concept, we show that the pulmonary delivery of targeted CAKSMGDIVC-displaying phage particles in mice and non-human primates elicit a systemic and specific humoral response. CONCLUSIONS: This broad methodology blueprint represents a robust and versatile platform tool enabling new ligand-receptor discovery with many potential translational applications.

Forced oscillation technique in veterans with preserved spirometry and chronic respiratory symptoms.

PURPOSE: To evaluate the utility of the forced oscillation technique (FOT) among military veterans with preserved spirometry and chronic unexplained respiratory symptoms. METHODS: 178 veterans referred for evaluation of unexplained respiratory symptoms completed pulmonary function testing and FOT. Preserved spirometry was defined as FEV1/FVC, FEV1 and FVC ≥ 5th percentile. Frequency dependence of resistance (R4-R20) and reactance area (AX) were assessed via FOT, and R4-R20 ≥ 20% and AX ≥ 95th percentile were considered abnormal. RESULTS: Spirometry was preserved in 71.3%, of whom 124 had acceptable FOT data. 93 of 124 (75.0%) veterans with preserved spirometry had one or more abnormal findings on FOT. Veterans with abnormal R4-R20 and/or AX had reduced FVC, FEV1, FEF25-75, and diffusing capacity (% predicted) in comparison to those with Normal FOT (p = 0.030 to p < 0.001). CONCLUSIONS: In our referral sample, distal airway dysfunction in the presence of preserved spirometry appears common and may represent an at-risk group requiring closer surveillance.

Influenza immunization among resident physicians in an urban teaching hospital.

We surveyed resident physicians (RPs) at an academic medical center to determine the rate of influenza vaccination and reasons for nonvaccination. The overall self-reported immunization rate of RPs in 2013-2014 was 76.7%, and the most common reason for not being vaccinated was lack of time to get immunized (38.6%). Making flu vaccination available in training hospitals and at convenient locations and times that take into account varying work schedules may increase compliance.

A Man in His 20s With Diffuse Lung Opacities and Acute Respiratory Failure After Hookah Smoking.

A man in his 20s with no medical history presented with 2 days of progressively worsening shortness of breath accompanied by subjective fevers, chills, body aches, decreased appetite, night sweats, and cough producing nonbloody sputum. He denied childhood lung diseases, allergies, or a family history of lung disease. He did not smoke cigarettes but had smoked hookah in Saudi Arabia before moving to the United States 1 month before presentation and had restarted 2 days before the start of symptoms. He denied travel outside of the northeastern United States. He did not take medications, use illicit drugs, or engage in high-risk behavior.

Palliative and end-of-life educational practices in US pulmonary and critical care training programs.

PURPOSE: To describe educational features in palliative and end-of-life care (PEOLC) in pulmonary/critical care fellowships and identify the features associated with perceptions of trainee competence in PEOLC. METHODS: A survey of educational features in 102 training programs and the perceived skill and comfort level of trainees in 6 PEOLC domains: communication, symptom control, ethical/legal, community/institutional resources, specific syndromes, and ventilator withdrawal. We evaluated associations between perceived trainee competence/comfort in PEOLC and training program features, using regression analyses. RESULTS: Fifty-five percent of program directors (PDs) reported faculty with training in PEOLC; 30% had a written PEOLC curriculum. Neither feature was associated with trainee competence/comfort. Program directors and trainees rated bedside PEOLC teaching highly. Only 20% offered PEOLC rotations; most trainees judged these valuable. Most PDs and trainees reported that didactic teaching was insufficient in communication, although sufficient teaching of this was associated with perceived trainee competence in communication. Perceived trainee competence in managing institutional resources was rated poorly. Program directors reporting significant barriers to PEOLC education also judged trainees less competent in PEOLC. Time constraint was the greatest barrier. CONCLUSION: This survey of PEOLC education in US pulmonary/critical care fellowships identified associations between certain program features and perceived trainee skill in PEOLC. These results generate hypotheses for further study.

Diagnosis and treatment of pulmonary embolism in the elderly.

Pulmonary embolism (PE) is a difficult diagnosis in patients of all ages, but more so in the elderly. Nonspecific symptoms and laboratory results are often misattributed to common diseases or to age itself, and can delay or even deter the diagnosis and treatment of PE. Advanced age is sometimes mistakenly seen as a contraindication to anticoagulation and thrombolysis. Together, these factors contribute to the higher morbidity and mortality associated with PE in the elderly than in younger patients. This article reviews the risk factors, diagnosis, and treatment of PE as it applies to the elderly.

Impact of critical care medicine training programs' palliative care education and bedside tools on ICU use at the end of life.

BACKGROUND: Intensive care unit (ICU) use at the end of life is rising. Little research has focused on associations among critical care fellows' training, institutional support, and bedside tools with ICU use at the end of life. OBJECTIVE: We evaluated whether hospital and critical care medicine program interventions were associated with ICU use in the last 6 months of life for patients with chronic illness. METHODS: Our observational, retrospective study explored associations between results from a survey of critical care program directors and hospital-level Medicare data on ICU use in the last 6 months of life. Program directors evaluated quality of palliative care education in their critical care fellowships and reported on the number of bedside tools and the presence or absence of an inpatient palliative care consultation service. RESULTS: For the 89 hospitals and 71 affiliated training programs analyzed, there were statistically significant relationships between 2 of the explanatory variables-the quality of palliative care education and the number of bedside tools-in ICU use. Each level of increased educational quality (1-5 Likert scale) was associated with a 0.57-day decrease in ICU days, whereas, for each additional, evidence-based bedside tool, there was a 0.31-day decrease. The presence of an inpatient palliative care program was not a significant predictor of ICU use. CONCLUSIONS: We found that the quality of palliative care training in critical care medicine programs and the use of bedside tools were independently associated with reduced ICU use at the end of life.

Association of patient-provider communication domains with lung cancer treatment.

BACKGROUND: Patient-physician communication is critical for helping patients understand and complete the complex steps needed to diagnose stage and treat lung cancer. We assessed which domains of patient-physician communication about lung cancer and its treatment are associated with receipt of disease-directed, stage-appropriate treatment. METHODS: Patients with recently diagnosed lung cancer were recruited from four medical centers in New York City from 2008 to 2011. Participants were surveyed about discussions with physicians regarding treatment, symptoms, and needs. Multiple regression analysis and structural equation modeling were used to assess which communication factors were associated with disease treatment. RESULTS: Of the 352 participants, 191 (54%) received disease-directed, stage-appropriate treatment. Unadjusted associations between communication items and treatment found that participants who felt that their physicians explained the risks and disadvantages of lung cancer treatment (p < 0.01), discussed their chances of cure (p = 0.02), discussed goals of treatment (p < 0.01), or who were warm and friendly (p = 0.04) were more likely to undergo treatment. Three communication domains were identified: treatment information, physician support, and patient symptoms/needs. After adjusting for known determinants of lung cancer treatment, increased treatment information was associated with higher probability of cancer-directed treatment (p = 0.003). Other communication domains (physician support or patient symptoms/needs) were not independent predictors of treatment (p > 0.05 for both comparisons). CONCLUSION: These data suggest that treatment information is particularly important for increasing the probability of cancer-directed therapy among lung cancer patients. Clinicians should ensure that they clearly discuss treatment goals and options with patients while maintaining empathy, supporting patient needs, and addressing symptoms.

Cultural factors associated with racial disparities in lung cancer care.

RATIONALE: Minority patients with lung cancer are less likely to receive stage-appropriate treatment. Along with access to care and provider-related factors, cultural factors such as patients' lung cancer beliefs, fatalism, and medical mistrust may help explain this disparity. OBJECTIVES: To determine cultural factors associated with disparities in lung cancer treatment. METHODS: Patients with newly diagnosed lung cancer were recruited from four medical centers in New York City from 2008 to 2011. Using validated tools, we surveyed participants about their beliefs regarding lung cancer, fatalism, and medical mistrust. We compared rates of stage-appropriate treatment among blacks, Hispanics, and nonminority patients. Multiple regression analyses and structural equation modeling were used to assess whether cultural factors are associated with and/or mediate disparities in care. MEASUREMENTS AND MAIN RESULTS: Of the 352 patients with lung cancer in the study, 21% were black and 20% were Hispanic. Blacks were less likely to receive stage-appropriate treatment (odds ratio [OR], 0.50; 95% confidence interval [CI], 0.27-0.93) compared with whites, even after adjusting for age, sex, marital status, insurance, income, comorbidities, and performance status. No differences in treatment rates were observed among Hispanics (OR, 1.05; 95% CI, 0.53-2.07). Structural equation modeling showed that cultural factors (negative surgical beliefs, fatalism, and medical mistrust) partially mediated the relationship between black race and lower rates of stage-appropriate treatment (total effect: -0.43, indirect effect: -0.13; 30% of total effect explained by cultural factors). CONCLUSIONS: Negative surgical beliefs, fatalism, and mistrust are more prevalent among minorities and appear to explain almost one-third of the observed disparities in lung cancer treatment among black patients. Interventions targeting cultural factors may help reduce undertreatment of minorities.

Chest radiograph findings and time to culture conversion in patients with multidrug-resistant tuberculosis and HIV in Tugela Ferry, South Africa.

BACKGROUND: The majority of patients with multidrug-resistant tuberculosis (MDR-TB) in South Africa are co-infected with HIV, but the radiographic features of MDR-TB and their relationship with time to sputum culture conversion in the antiretroviral therapy era have not been described. METHODS: We reviewed baseline chest radiographs for 56 patients with MDR-TB from a rural area of South Africa. We analyzed the association of cavities, consolidation, pleural effusion and hilar lymphadenopathy with time to sputum culture conversion, adjusting for HIV status, baseline sputum smear and CD4 count. RESULTS: Of the 56 subjects, 49 (88%) were HIV-positive, with a median CD4 count of 136 cells/mm(3) (IQR 65-249). Thirty-two (57%) patients were sputum smear positive. Twenty-two (39%) patients had a cavity and 37 (66%) patients had consolidations. Cavitary disease and consolidations were each associated with longer time to culture conversion on bivariate analysis but not after adjusting for sputum smear status (aORs 1.79 [0.94-3.42] and 1.09 [0.67-1.78], respectively). Positive baseline sputum smear remained independently associated with longer time to conversion (aOR 3.45 [1.39-8.59]). We found no association between pleural effusion or hilar lymphadenopathy and time to conversion. Seventy-nine percent of patients were cured at the end of treatment. CONCLUSIONS: Despite high rates of HIV co-infection and advanced immunodeficiency, the majority of patients had severe pathology on baseline chest radiograph. Nevertheless, culture conversion rates were high and treatment outcomes were favorable. Cavitation and consolidation do not appear to have an independent association with time to culture conversion beyond that of baseline sputum smear status.

Racial and ethnic differences in beliefs about lung cancer care.

BACKGROUND: Disparities in lung cancer treatment and palliative care are well documented. However,the mechanisms underlying these disparities are not fully understood. In this study, we evaluated racial and ethnic differences in beliefs and attitudes about lung cancer treatment and palliative care among patients receiving a new diagnosis of lung cancer. METHODS: Patients were recruited from four medical centers in New York City and surveyed about their beliefs regarding lung cancer care, including disease-directed treatments, palliative and end-of-life care, and fatalistic and spiritual beliefs. We used univariate and multiple regression analyses to compare the distribution of beliefs among minority (black and Hispanic) and nonminority patients. RESULTS: Of the 335 patients, 21% were black, 20% were Hispanic, and 59% were nonminority. Beliefs about chemotherapy and radiotherapy were similar across the three groups ( P > .05),whereas black patients were more likely to believe that surgery might cause lung cancer to spread( P =.008). Fatalistic beliefs potentially affecting cancer treatment were more common among both minority groups ( P ≤ .02). No signifi cant differences were found in attitudes toward clinician communication about cancer prognosis ( P > .05). However, both blacks and Hispanics were more likely to have misconceptions about advance directives and hospice care ( P ≤ .02). CONCLUSIONS: Similarities and differences in beliefs about disease-directed treatment were observed between minority and nonminority patients with lung cancer. Minority patients hold more fatalistic views about the disease and misperceptions about advance care planning and hospice care. Further research is needed to assess the impact of these beliefs on decisions about lung cancer care and patient outcomes.

Management of patients with end-stage chronic obstructive pulmonary disease.

Patients with end-stage chronic obstructive pulmonary disease (COPD) have poor quality of life, with limited activity, breathlessness, dependence on others, and recurrent needs for medical evaluation and treatment. Such patients demonstrate significant and progressive impairments in physical, mental, and social functioning. Because the rate of decline is variable, however, it is difficult to predict prognosis of survival. Currently available treatments only partially relieve symptoms, and patients become increasingly more disabled. This article reviews quality of life issues, proposed prognostic indicators, and pharmacologic and nonpharmacologic treatments in advanced COPD. Palliative measures to address breathlessness and unmet needs among patients with end-stage COPD are discussed.
