A nurse-delivered intervention to reduce insomnia in cancer survivors: Study protocol for a randomized-controlled trial.

Insomnia has been frequently reported as one of the most burdensome symptoms among cancer survivors. To date, little research exists on strategies to effectively reduce insomnia in cancer survivors, especially in the application of cognitive behavioral therapy for insomnia (CBTI) at the bedside by nurses. The current objective is to determine efficacy and durability of a streamlined, individually delivered version of CBTI, specifically Brief Behavioral Therapy for Insomnia (BBTI) versus a healthy eating attention control, using a large heterogeneous sample of 158 cancer survivors. Study participants will be adults ≥18 years of age; ≥1 month from treatment (except hormones and targeted therapies are acceptable) for stages I through III breast, colorectal, lung or prostate cancers; meet criteria for insomnia defined by Insomnia Severity Index (ISI) >7; screen negative for obstructive sleep apnea <15 events/h; and ability to complete data collection instruments in English. Baseline, and then 1-, 3-, and 12-month objective (i.e., actigraphy) and subjective sleep, mood, and quality of life assessments after the interventions are planned. The primary outcome will be measured with the ISI, a psychometrically-sound instrument used to measure perceived insomnia severity. The results of this trial will demonstrate the application of BBTI in a larger heterogenous sample of cancer survivors for the first time and may lead to implementation strategies that will promote the dissemination and sustainability of this intervention.

Validation of the Behavioral Risk Factor Surveillance System Sleep Questions.

STUDY OBJECTIVES: leep problems may constitute a risk for health problems, including cardiovascular disease, depression, diabetes, poor work performance, and motor vehicle accidents. The primary purpose of this study was to assess the validity of the current Behavioral Risk Factor Surveillance System (BRFSS) sleep questions by establishing the sensitivity and specificity for detection of sleep/ wake disturbance. METHODS: Repeated cross-sectional assessment of 300 community dwelling adults over the age of 18 who did not wear CPAP or oxygen during sleep. Reliability and validity testing of the BRFSS sleep questions was performed comparing to BFRSS responses to data from home sleep study, actigraphy for 14 days, Insomnia Severity Index, Epworth Sleepiness Scale, and PROMIS-57. RESULTS: Only two of the five BRFSS sleep questions were found valid and reliable in determining total sleep time and excessive daytime sleepiness. CONCLUSIONS: Refinement of the BRFSS questions is recommended.

Radiographic resolution of community-acquired bacterial pneumonia in the elderly.

OBJECTIVES: To investigate the radiographic clearance of proven community-acquired nontuberculous bacterial pneumonia in nonimmunocompromised older patients to provide working estimates of the rate of radiographic resolution as a function of the patient cumulative comorbidities, extent of initial radiographic involvement, functional status, and causative pathogens. DESIGN: A prospective study. PARTICIPANTS: Seventy-four patients aged 70 and older, consecutively admitted to a hospital for community-acquired bacterial pneumonia. SETTING: A university-affiliated teaching hospital. MEASUREMENTS: Chest radiographs were performed every 3 weeks from the date of admission for a total period of 12 weeks or until all radiographic abnormalities had resolved or returned to baseline. RESULTS: Sixty-four patients (86%) completed the study. The rate of radiographic clearance was estimated at 35.1% within 3 weeks, 60.2% within 6 weeks, and 84.2% within 12 weeks. Radiographic resolution was significantly slower for those with high comorbidity index, bacteremia, multilobar involvement, and enteric gram-negative bacilli pneumonias. Multivariate regression analysis demonstrated that the comorbidity index (relative risk for clearance=0.67 per class index, P<.001) and multilobar disease (relative risk for clearance=0.24 for more than one lobe, P<.001) had independent predictive value (Cox proportional hazards regression model) on the rate of resolution. CONCLUSION: The radiographic resolution of nontuberculous bacterial pneumonia in the elderly should take into account the extent of lobar disease and the burden of underlying illnesses. A waiting period of 12 to 14 weeks is recommended for slowly resolving pneumonia to be considered nonresolving.

Microbiology of severe aspiration pneumonia in institutionalized elderly.

We sought to investigate prospectively the microbial etiology and prognostic indicators of 95 institutionalized elders with severe aspiration pneumonia, and to investigate its relation to oral hygiene in using quantitative bronchial sampling. Data collection included demographic information, Activity of Daily Living, Plaque Index, antimicrobial therapy, and outcome. Out of the 67 pathogens identified, Gram-negative enteric bacilli were the predominant organisms isolated (49%), followed by anaerobic bacteria (16%), and Staphylococcus aureus (12%). The most commonly encountered anaerobes were Prevotella and Fusobacterium species. Aerobic Gram-negative bacilli were recovered in conjunction with 55% of anaerobic isolates. The Plaque Index did not differ significantly between the aerobic (2.2 +/- 0.4) and the anaerobic group (2.3 +/- 0.3). Functional status was the only determinant of the presence of anaerobic bacteria. Although seven cases with anaerobic isolates received initially inadequate antimicrobial therapy, six had effective clinical response. The crude mortality was 33% for the aerobic and 36% for the anaerobic group (p = 0.9). Stepwise multivariate analysis identified hypoalbuminemia (p < 0.001) and the burden of comorbid diseases (p < 0.001) as independent risk factors of poor outcome. In view of the rising resistance to antimicrobial agents, the importance of adding anaerobic coverage for aspiration pneumonia in institutionalized elders needs to be reexamined.

Impact of invasive strategy on management of antimicrobial treatment failure in institutionalized older people with severe pneumonia.

The aim of the study was to investigate the etiology and the impact of invasive quantitative sampling on the management of severe pneumonia in institutionalized older people with antimicrobial treatment failure. Fifty-two institutionalized patients aged 70 years and older hospitalized with a presumptive diagnosis of severe pneumonia and failure to respond to treatment after 72 hours of initiation of outpatient antimicrobial therapy were enrolled. Microbial investigation included blood culture, serology, pleural fluid, and bronchoalveolar samples. A definite etiology could be established in 24 of 52 (46%) patients. Methicillin-resistant Staphylococcus aureus (33%), enteric Gram-negative bacilli (24%), and Pseudomonas aeruginosa (14%) accounted for most isolates. Atypical infections (2%) were uncommon. Invasive bronchial sampling directed a change of microbial therapy in 8 (40%) and discontinuation of antibiotics in 2 of 20 cases (10%) of definite pneumonia. Overall hospital mortality was 42%. There was no difference in mortality among definite or unverified cases or those who had invasive bronchial sampling-guided change in therapy. We conclude that antimicrobial therapy should be targeted toward "nosocomial" pathogens in those institutionalized patients who received prior antibiotic treatment. When combined with microbial investigation, direct visualization of the tracheobronchial tree might be useful in determining the presence of bacterial pneumonia.
