This document provides evidence-based clinical practice guidelines on the management of adult patients with community-acquired pneumonia.
A multidisciplinary panel conducted pragmatic systematic ...reviews of the relevant research and applied Grading of Recommendations, Assessment, Development, and Evaluation methodology for clinical recommendations.
The panel addressed 16 specific areas for recommendations spanning questions of diagnostic testing, determination of site of care, selection of initial empiric antibiotic therapy, and subsequent management decisions. Although some recommendations remain unchanged from the 2007 guideline, the availability of results from new therapeutic trials and epidemiological investigations led to revised recommendations for empiric treatment strategies and additional management decisions.
The panel formulated and provided the rationale for recommendations on selected diagnostic and treatment strategies for adult patients with community-acquired pneumonia.
Annual lung cancer screening (LCS) has mortality benefits for eligible participants; however, studies demonstrate low adherence to follow-up LCS.
What are patients’ perspectives on barriers and ...facilitators to adherence to annual LCS?
Forty participants enrolled in the University of Washington/Seattle Cancer Care Alliance LCS program completed a demographic questionnaire and a semistructured interview based on the Tailored Implementation in Chronic Diseases framework to determine attitudes, barriers, and facilitators to longitudinal LCS. Interviews were coded using principles of framework analysis to identify and compare themes between adherent and nonadherent participants.
The 40 participants underwent initial LCS in 2017 with negative results. Seventeen were adherent to follow-up annual LCS, whereas 23 were not. Seven overall themes emerged from qualitative analysis, which are summarized as follows: (1) screening experiences are positive and participants have positive attitudes toward screening; (2) provider recommendation is a motivator and key facilitator for most patients; (3) many patients are influenced by personal factors and symptoms and do not understand the importance of asymptomatic screening; (4) common barriers to longitudinal screening include cost, insurance coverage, accessibility, and other medical conditions; (5) patients have variable preferences about how they receive their screening results, and many have residual questions about their results and future screening; (6) reminders are an important facilitator of annual screening; and (7) most patients think a navigator would be beneficial to the screening process, with different aspects of navigation thought to be most helpful. Those who were not adherent more commonly reported individual barriers to screening, competing health concerns, and less provider communication.
Key facilitators (eg, patient reminders, provider recommendations) may improve long-term screening behavior, and a number of barriers to the screening process could be addressed through patient navigation.
Abstract Objective To estimate the survival and quality-adjusted life-years (QALYs) of Full Code versus Do Not Intubate (DNI) advance directives in patients with severe chronic obstructive pulmonary ...disease and to evaluate how patient preferences and place of residence influence these outcomes. Methods A Markov decision model using published data for COPD exacerbation outcomes. The advance directives that were modeled were as follows: DNI, allowing only noninvasive mechanical ventilation, or Full Code, allowing all forms of mechanical ventilation including invasive mechanical ventilation with endotracheal tube (ETT) insertion. Results In community-dwellers, Full Code resulted in a greater likelihood of survival and higher QALYs (4-year survival: 23% Full Code, 18% DNI; QALYs: 1.34 Full Code, 1.24 DNI). When considering patient preferences regarding complications, however, if patients were willing to give up >3 months of life expectancy to avoid ETT complications, or >1 month of life expectancy to avoid long-term institutionalization, DNI resulted in higher QALYs. For patients in long-term institutions, DNI resulted in a greater likelihood of survival and higher QALYs (4-year survival: 2% DNI, 1% Full Code; QALYs: 0.29 DNI, 0.24 Full Code). In sensitivity analyses, the model was sensitive to the probabilities of ETT complication and noninvasive mechanical ventilation failure and to patient preferences about ETT complications and long-term institutionalization. Conclusion Our model demonstrates that patient preferences regarding ETT complications and long-term institutionalization, as well as baseline place of residence, affect the advance directive recommendation when considered in terms of both survival and QALYs. Decision modeling can demonstrate the potential trade-off between survival and quality of life, using patient preferences and disease-specific data, to inform the shared advance directive decision.
Advance directives (AD) may promote preference-concordant care yet are absent in many patients with Chronic Obstructive Pulmonary Disease (COPD). In order to begin to inform AD discussions between ...clinicians and COPD patients, we constructed a decision tree to estimate the impact of alternative AD decisions on both quality and quantity of life (quality adjusted life years, QALYs).
Two aspects of the AD were considered, Do Not Intubate (DNI; i.e., no invasive mechanical ventilation) and Full Code (i.e., may use invasive mechanical ventilation). Model parameters were based on published estimates. Our model follows hypothetical patients with COPD to evaluate the effect of underlying COPD severity and of hypothetical patient-specific preferences (about long-term institutionalization and complications from invasive mechanical ventilation) on the recommended AD.
Our theoretical model recommends endorsing the Full Code advance directive for patients who do not have strong preferences against having a potential complication from intubation (ETT complications) or being discharged to a long-term ECF. However, our model recommends endorsing the DNI advance directive for patients who do have strong preferences against having potential complications of intubation and are were willing to tradeoff substantial amounts of time alive to avoid ETT complications or permanent institutionalization. Our theoretical model also recommends endorsing the DNI advance directive for patients who have a higher probability of having complications from invasive ventilation (ETT).
Our model suggests that AD decisions are sensitive to patient preferences about long-term institutionalization and potential complications of therapy, particularly in patients with severe COPD. Future work will elicit actual patient preferences about complications of invasive mechanical ventilation, and incorporate our model into a clinical decision support to be used for actual COPD patients facing AD decisions.

Background. Weight gain after antiretroviral therapy (ART) initiation is common, but its implication for mortality is unknown. We evaluated weight change in the first year after ART initiation and ...its association with subsequent mortality. Methods. Human immunodeficiency virus-infected patients from the Veterans Aging Cohort Study (VACS) who initiated ART between 2000 and 2008, with weight recorded at baseline and 1 year later, were followed another 5 years for mortality. Baseline body mass index (BMI) was classified as underweight (<18.5 kg/m2), normal (18.5–24.9 kg/m2), overweight (25–29.9 kg/m2), and obese (≥30 kg/m2). We used multivariable Cox models to assess mortality risk with adjustment for disease severity using the VACS Index. Results. The sample consisted of 4184 men and 127 women with a mean age of 47.9 ± 10.0 years. After 1 year of ART, median weight change was 5.9 pounds (2.7 kg) (interquartile range, −2.9 to 17.0 pounds, −1.3 to 7.7 kg). Weight gain after ART initiation was associated with lower mortality among underweight and normal-weight patients. A minimum threshold of 10- to 19.9-pound (4.5 to 9.0 kg) weight gain was beneficial for normal-weight patients (hazard ratio, 0.56; 95% confidence interval, .41–.78), but there was no clear benefit to weight gain for overweight/obese patients. Baseline weight, CD4 cell count status, and hemoglobin level were strongly associated with weight gain. Risk for weight gain was higher among those with greater disease severity, regardless of weight at initiation. Conclusions. The survival benefits of weight gain after ART initiation are dependent on starting BMI. Weight gain after ART is associated with lower mortality for those who are not initially overweight.
