Abstract
BACKGROUND The clinical presentation of acute pulmonary embolism (PE) can range from mild symptoms to severe shock, circulatory arrest and even death, thereby presenting with a significant high mortality when undiagnosed. Computed tomography pulmonary angiography (CTPA) is the gold-standard imaging modality for diagnosing PE, however, it has several practical limitations and is not widely available in low-income country settings. In this context, point-of-care ultrasound (POCUS) has emerged as a valuable bedside, non-invasive diagnostic tool. This meta-analysis assesses the accuracy of multi-organ POCUS for diagnosing PE in critical care settings. STUDY DESIGN AND METHODS We conducted a systematic search of Pubmed, Embase, Scopus and the Cochrane Library databases for studies comparing multi-organ POCUS with CTPA or ventilation-perfusion scans for PE diagnosis in critical care departments. Two reviewers independently completed search, data abstraction and conducted quality assessment with QUADAS-2 tool. Heterogeneity was examined with I2 statistics. We used a bivariate model of random effects to summarize pooled diagnostic odds ratio (DOR), sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR) and summary receiver operating characteristic (SROC). RESULTS Four studies met the inclusion criteria, comprising 594 patients. The mean age of participants ranged from 55.2 to 71 years. Prevalence of PE ranged from 28 to 66.2%. CTPA was the primary reference standard used in most studies. Multi-organ POCUS for PE diagnosis demonstrated a pooled DOR of 25.3 (95% CI 4.43-82.9) with a pooled sensitivity of 0.90 (95% CI 0.85-0.94; I2 = 0%) and specificity of 0.69 (95% CI 0.42-0.87; I2 = 95%). The PLR was 3.35 (95% CI 1.43-8.02) and the NLR was 0.16 (95% CI 0.08-0.32). The SROC curve showed an AUC of 0.89 (95% CI 0.81-0.94). CONCLUSIONS Multi-organ POCUS has high diagnostic accuracy for PE diagnosis in critically ill patients. Further research is needed to validated these findings across different patient populations.

Abstract
Background Falls are frequent among people with chronic obstructive pulmonary disease (COPD) and are associated with increased morbidity, mortality, and health care costs. Understanding modifiable medication factors that contribute to fall risk is an important step to developing fall prevention strategies for this highly susceptible group. Methods This is a retrospective cohort study using electronic health record data from a single health system linked to Washington State death certificates of adults ages 40 or older who died between 2014-2018 with COPD. We identified demographics, comorbidities, fall-risk increasing drug (FRID) burden, and the occurrence of injurious falls within the 2 years prior to the date of death. We defined injurious falls using published algorithms of the International Classification of Diseases codes. Results Of 8204 decedents with COPD, 2454 (30%) had an injurious fall in the 2 years before death, and FRID use was common among 65%. A higher percentage of patients with falls received prescriptions for anticonvulsants (35% versus 26%), antipsychotics (24% versus 13%), atypical antidepressants (28% versus 19%), and tricyclic antidepressants (10% versus 5%) versus those without a fall. In multivariable logistic regression, after adjusting for confounders, FRID burden was associated with greater odds of an injurious fall (odds ratio 1.07 [95% confidence interval 1.04-1.09]). Conclusion Our findings highlight an opportunity for collaboration between pharmacists, pulmonologists, and patients to develop new processes to potentially deprescribe and optimize the use of FRIDs among patients with COPD to increase safety.

Supplemental Oxygen Use, Outcomes, and Spending in Patients With COPD in the Medicare Competitive Bidding Program. JAMA Intern Med 2024:2825456. [PMID: 39466279 PMCID: PMC11581493 DOI: 10.1001/jamainternmed.2024.5738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Accepted: 09/03/2024] [Indexed: 10/29/2024]
Abstract
Importance The Medicare Competitive Bidding Program (CBP), a policy that reduced durable medical equipment prices, was implemented starting in 2011. Legislation introduced in 2024 aims to remove supplemental oxygen from the CBP because of concerns that recent decreases in oxygen prescribing are due to lower prices set by the CBP, which may have decreased supply and, in turn, limited oxygen access for patients with chronic lung diseases. However, low-value prescribing of oxygen is also prevalent in practice, and decreased oxygen prescription rates may not have necessarily caused harm. Little is known about the association of the CBP with patient use, outcomes, or spending. Objective To examine the association between the 2011 and 2013 implementation of the CBP and supplemental oxygen use, clinical outcomes, and supplemental oxygen spending among patients with chronic obstructive pulmonary disease (COPD). Design, Setting, and Participants This cohort study used a difference-in-differences (DID) method to evaluate the association between implementation of the CBP and the outcomes of interest. Patients aged 65 to 100 years with COPD living in CBP areas were compared with those living in areas where the CBP was not yet or never implemented. The study included 100% fee-for-service Medicare data of beneficiaries enrolled between July 1, 2009, and December 31, 2015. The data analysis was performed between June 6, 2023, and August 16, 2024. Exposure The 2011 and 2013 implementation cycles of the Medicare CBP. Main Outcomes and Measures The primary outcomes were new prescriptions of oxygen during a 6-month period among beneficiaries with COPD and discontinuation of oxygen during a 6-month period among beneficiaries with COPD previously prescribed oxygen. Secondary outcomes included switches between oxygen types (gas, liquid, or concentrator), all-cause mortality, all-cause unplanned hospitalizations, COPD hospitalizations, and mean monthly allowed charges (total spending) over a 6-month period. The analysis was performed using the Callaway-Sant'Anna method, a dynamic DID model for policies with staggered implementation. Results Among 5 753 308 Medicare beneficiaries with COPD (mean [SD] age, 79.2 [8.4] years; 55.1% female), 25.9% received supplemental oxygen for at least one 6-month period during the study. The CBP was not associated with differential changes in new oxygen prescribing (DID estimate, -0.19 percentage points; 95% CI, -2.45 to 2.08 percentage points) or oxygen discontinuations (DID estimate, -0.77 percentage points; 95% CI, -8.15 to 6.60 percentage points). Similarly, differential changes were not observed in the secondary outcomes of oxygen switches (DID estimate, -0.04 percentage points; 95% CI, -0.44 to 0.37 percentage points), all-cause mortality (DID estimate, 0.16 percentage points; 95% CI, -7.52 to 7.84 percentage points), all-cause unplanned hospitalizations (DID estimate, -0.20 percentage points; 95% CI, -10.94 to 10.53 percentage points), or COPD hospitalizations (DID estimate, -0.04 percentage points; 95% CI, -2.57 to 2.48 percentage points). Differential changes were observed for mean monthly allowed charges (DID estimate, -$326.22; 95% CI, -$434.76 to -$217.68). Conclusions and Relevance In this study, among beneficiaries with COPD, the Medicare CBP was associated with differentially lower spending but not differential changes in oxygen use or clinical outcomes. This study did not find evidence supporting ongoing policy efforts to remove supplemental oxygen from the CBP.

Abstract
This Thoracic Society of Australia and New Zealand Guideline on the provision of home oxygen therapy in adults updates a previous Guideline from 2015. The Guideline is based upon a systematic review and meta-analysis of literature to September 2022 and the strength of recommendations is based on GRADE methodology. Long-term oxygen therapy (LTOT) is recommended for its mortality benefit for patients with COPD and other chronic respiratory diseases who have consistent evidence of significant hypoxaemia at rest (PaO2 ≤ 55 mm Hg or PaO2 ≤59 mm Hg in the presence of hypoxaemic sequalae) while in a stable state. Evidence does not support the use of LTOT for patients with COPD who have moderate hypoxaemia or isolated nocturnal hypoxaemia. In the absence of hypoxaemia, there is no evidence that oxygen provides greater palliation of breathlessness than air. Evidence does not support the use of supplemental oxygen therapy during pulmonary rehabilitation in those with COPD and exertional desaturation but normal resting arterial blood gases. Both positive and negative effects of LTOT have been described, including on quality of life. Education about how and when to use oxygen therapy in order to maximize its benefits, including the use of different delivery devices, expectations and limitations of therapy and information about hazards and risks associated with its use are key when embarking upon this treatment.

Efficacy and Impact of a Multimodal Intervention on CT Pulmonary Angiography Ordering Behavior in the Emergency Department. J Am Coll Radiol 2024; 21:309-318. [PMID: 37247831 DOI: 10.1016/j.jacr.2023.02.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/26/2023] [Accepted: 02/04/2023] [Indexed: 05/31/2023]
Abstract
OBJECTIVE To evaluate the efficacy of a multimodal intervention in reducing CT pulmonary angiography (CTPA) overutilization in the evaluation of suspected pulmonary embolism in the emergency department (ED). METHODS Previous mixed-methods analysis of barriers to guideline-concordant CTPA ordering results was used to develop a provider-focused behavioral intervention consisting of a clinical decision support tool and an audit and feedback system at a multisite, tertiary academic network. The primary outcome (guideline concordance) and secondary outcomes (yield and CTPA and D-dimer order rates) were compared using a pre- and postintervention design. ED encounters for adult patients from July 5, 2017, to January 3, 2019, were included. Fisher's exact tests and statistical process control charts were used to compare the pre- and postintervention groups for each outcome. RESULTS Of the 201,912 ED patient visits evaluated, 3,587 included CTPA. Guideline concordance increased significantly after the intervention, from 66.9% to 77.5% (P < .001). CTPA order rate and D-dimer order rate also increased significantly, from 17.1 to 18.4 per 1,000 patients (P = .035) and 30.6 to 37.3 per 1,000 patients (P < .001), respectively. Percent yield showed no significant change (12.3% pre- versus 10.8% postintervention; P = .173). Statistical process control analysis showed sustained special-cause variation in the postintervention period for guideline concordance and D-dimer order rates, temporary special-cause variation for CTPA order rates, and no special-cause variation for percent yield. CONCLUSION Our success in increasing guideline concordance demonstrates the efficacy of a mixed-methods, human-centered approach to behavior change. Given that neither of the secondary outcomes improved, our results may demonstrate potential limitations to the guidelines directing the ordering of CTPA studies and D-dimer ordering.

Abstract
Rationale: Interventions to promote adherence to long-term oxygen therapy (LTOT) in chronic obstructive pulmonary disease (COPD) are needed. Objectives: To examine the real-world effectiveness of phone-based peer coaching on LTOT adherence and other outcomes in a pragmatic trial of patients with COPD. Methods: In a hybrid effectiveness/implementation pragmatic trial, patients were randomized to receive phone-based proactive coaching (educational materials, five phone-based peer coaching sessions over 60 d), reactive coaching (educational materials, peer coaching when requested), or usual care. Study staff members collected baseline and outcome data via phone at 30, 60, and 90 days after randomization. Adherence to LTOT over 60 days, the primary effectiveness outcome, was defined as mean LTOT use ⩾17.7 h/d. LTOT use was calculated using information about home oxygen equipment use in worksheets completed by study participants. Comparisons of adherence to LTOT between each coaching group and the usual care group using multivariable logistic regression models were prespecified as the primary analyses. Secondary effectiveness outcomes included Patient Reported Outcome Management Information System measures for physical, emotional, and social health. We assessed early implementation domains in the reach, adoption, and implementation framework. Results: In 444 participants, the proportions who were adherent to LTOT at 60 days were 74% in usual care, 84% in reactive coaching, and 70% in proactive coaching groups. Although reach, adoption by stakeholder partners, and intervention fidelity were acceptable, complete LTOT adherence data were available in only 73% of participants. Reactive coaching (adjusted odds ratio, 1.77; 97.5% confidence interval, 0.80-3.90) and proactive coaching (adjusted odds ratio, 0.70; 97.5% confidence interval, 0.34-1.46) did not improve adherence to LTOT compared with usual care. However, proactive coaching significantly reduced depressive symptoms and sleep disturbance compared with usual care and reduced depressive symptoms compared with reactive coaching. Unexpectedly, LTOT adherence was significantly lower in the proactive compared with the reactive coaching group. Conclusions: The results were inconclusive about whether a phone-based peer coaching strategy changed LTOT adherence compared with usual care. Further studies are needed to confirm the potential benefits of proactive peer coaching on secondary effectiveness outcomes and differences in LTOT adherence between proactive and reactive peer coaching. Clinical trial registered with ClinicalTrials.gov (NCT02098369).

Sex differences in guideline-consistent diagnostic testing for acute pulmonary embolism among adult emergency department patients aged 18-49. Acad Emerg Med 2023; 30:896-905. [PMID: 36911917 PMCID: PMC10497718 DOI: 10.1111/acem.14722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 03/02/2023] [Accepted: 03/05/2023] [Indexed: 03/14/2023]
Abstract
BACKGROUND Pulmonary embolism (PE) is a frequent diagnostic consideration in emergency department (ED) patients, yet diagnosis is challenging because symptoms of PE are nonspecific. Guidelines recommend the use of clinical decision tools to increase efficiency and avoid harms from overtesting, including D-dimer screening in patients not at high risk for PE. Women undergo testing for PE more often than men yet have a lower yield from testing. Our study objective was to determine whether patient sex influenced the odds of received guideline-consistent care. METHODS We performed a retrospective cohort study at two large U.S. academic EDs from January 1, 2016, to December 31, 2018. Nonpregnant patients aged 18-49 years were included if they presented with chest pain, shortness of breath, hemoptysis, or syncope and underwent testing for PE with D-dimer or imaging. Demographic and clinical data were exported from the electronic medical record (EMR). Pretest risk scores were calculated using manually abstracted EMR data. Diagnostic testing was then compared with recommended testing based on pretest risk. The primary outcome was receipt of guideline-consistent care, which required an elevated screening D-dimer prior to imaging in all non-high-risk patients. RESULTS We studied 1991 discrete patient encounters; 37% (735) of patients were male and 63% (1256) were female. Baseline characteristics, including revised Geneva scores, were similar between sexes. Female patients were more likely to receive guideline-consistent care (70% [874/1256] female vs. 63% [463/735] male, p < 0.01) and less likely to be diagnosed with PE (3.1% [39/1256] female vs. 5.3% [39/735] male, p < 0.05). The most common guideline deviation in both sexes was obtaining imaging without a screening D-dimer in a non-high-risk patient (75% [287/382] female vs. 75% [205/272] male). CONCLUSIONS In this cohort, females were more likely than males to receive care consistent with current guidelines and less likely to be diagnosed with PE.

Abstract
This article is part of a series, Supporting Family Caregivers: No Longer Home Alone, published in collaboration with the AARP Public Policy Institute. Results of focus groups, conducted as part of the AARP Public Policy Institute's No Longer Home Alone video project, supported evidence that family caregivers aren't given the information they need to manage the complex care regimens of family members. This series of articles and accompanying videos aims to help nurses provide caregivers with the tools they need to manage their family member's health care at home. Nurses should read the articles first, so they understand how best to help family caregivers. Then they can refer caregivers to the informational tear sheet-Information for Family Caregivers-and instructional videos, encouraging them to ask questions.

Abstract
Rationale Short-term oxygen therapy (STOT) is often prescribed to allow patients with chronic obstructive pulmonary disease (COPD) to be discharged safely from hospital following an acute illness. This practice is widely accepted without being based on evidence. Purpose Our objective was to describe the characteristics and outcomes of patients with COPD who received STOT. Patients and Methods The study was a secondary analysis of the INOX trial, a 4-year randomised trial of nocturnal oxygen in COPD. The trial indicated that nocturnal oxygen has no significant effect on survival or progression to LTOT, allowing our merging of patients who received nocturnal oxygen and those who received placebo into a single cohort to study the predictors and outcomes of STOT regardless of the treatment received during the trial. Results Among the 243 participants in the trial, 60 required STOT on at least one occasion during follow-up. Patients requiring STOT had more severe dyspnoea and lung function impairment, and lower PaO2 at baseline than those who did not. STOT was associated with subsequent LTOT requirement (hazard ratio [HR]: 4.59; 95% confidence interval [CI]: 2.98–7.07) and mortality (HR: 1.93; 95% CI: 1.15–3.24). The association between STOT and mortality was confounded by age, disease severity and comorbidities. Periods of STOT of more than one month and/or repeated prescriptions of STOT increased the probability of progression to LTOT (OR: 5.07; 95% CI: 1.48–18.8). Conclusion Following an acute respiratory illness in COPD, persistent hypoxaemia requiring STOT is a marker of disease progression towards the requirement for LTOT.

Abstract
PURPOSE This study evaluated clinician adherence to the American College of Physicians Best Practice Advice for diagnosis of pulmonary embolism. DESIGN A prospective, single-center, descriptive design was utilized. METHODS A heterogeneous sample of 111 hemodynamically stable adult inpatients with a computed tomography pulmonary angiogram ordered was consented. Electronic medical records were reviewed for demographic and clinical variables to determine adherence. The 6 individual best practice statements and the overall adherence were evaluated by taking the sum of "yes" answers divided by the sample size. RESULTS Overall adherence was 0%. Partial adherence was observed with clinician-recorded clinical decisions rules and obtaining d-dimer (3.6% [4/111] and 10.2% [9/88], respectively) of low/intermediate probability scorers. Age adjustment of d-dimer was not recorded. Computed tomography pulmonary angiogram was the first diagnostic test in 89.7% (79/88) in low/intermediate probability patients. CONCLUSION In hemodynamically stable, hospitalized adults, adherence to best practice guidelines for diagnosis of pulmonary embolism was minimal. Clinical utility of the guidelines in hospitalized adults needs further evaluation. Systems problems (eg, lack of standardized orders, age-adjusted d-dimer values, information technology support) likely contributed to poor guideline adherence.

Abstract
Rationale: Hypoxemia associated with acute exacerbations of chronic obstructive pulmonary disease (COPD) often resolves with time. Current guidelines recommend that patients recently discharged with supplemental home oxygen after hospitalization should not have renewal of the prescription without assessment for hypoxemia. Understanding patterns of home oxygen reassessment is an opportunity to improve quality and value in home oxygen prescribing and may provide future targets for deimplementation.Objectives: We sought to measure the frequency of home oxygen reassessment within 90 days of hospitalization for COPD and determine the potential population eligible for deimplementation.Methods: We performed a cohort study of patients ≥40 years hospitalized for COPD at five Veterans Affairs facilities who were prescribed home oxygen at discharge. Our primary outcome was the frequency of reassessment within 90 days by oxygen saturation (SpO2) measurement. Secondary outcomes included the proportion of patients potentially eligible for discontinuation (SpO2 > 88%) and patients in whom oxygen was discontinued. Our primary exposures were treatment with long-acting bronchodilators, prior history of COPD exacerbation, smoking status, and pulmonary hypertension. We used a mixed-effects Poisson model to measure the association between patient-level variables and our outcome, clustered by site. We also performed a positive deviant analysis using chart review to uncover system processes associated with high-quality oxygen prescribing.Results: A total of 287 of 659 (43.6%; range 24.8-78.5% by site) patients had complete reassessment within 90 days. None of our patient-level exposures were associated with oxygen reassessment. Nearly half of those with complete reassessment were eligible for discontinuation on the basis of Medicare guidelines (43.2%; n = 124/287). When using the newest evidence available by the Long-Term Oxygen Treatment Trial, most of the cohort did not have resting hypoxemia (84.3%; 393/466) and would be eligible for discontinuation. The highest-performing Veterans Affairs facility had four care processes to support oxygen reassessment and discontinuation, versus zero to one at all other sites.Conclusions: Fewer than half of patients prescribed home oxygen after a COPD exacerbation are reassessed within 90 days. New system processes supporting timely reassessment and discontinuation of unnecessary home oxygen therapy could improve the quality and value of care.

Abstract
BACKGROUND Pulmonary embolism (PE) diagnosis can sometimes be challenging due to the disease having nonspecific signs and symptoms at the time of presentation. The present study aimed to evaluate the validity of the D-dimer in combination with the revised Geneva score (RGS) in the prediction of pulmonary embolism. PATIENTS AND METHODS This is a retrospective study of 2010 patients with suspected PE who had undergone both D-dimer testing followed by chest CT angiography (CTPA), irrespective of the D-dimer test results, at King Abdulaziz Medical City, Riyadh, Saudi Arabia, over 3 years, from Jan. 2016 to Jan. 2019. The predictive accuracy of D-dimer, adjusted D-dimer, and RGS was calculated. The receiver operating characteristic "ROC" curve was applied to allocate the optimum RGS cutoff for PE prediction. RESULTS The overall prevalence of PE was 16%. It was 0%, 25.8%, and 88.9% in low, intermediate, and high clinical probability categories of RGS, respectively. Both conventional and age-adjusted D-dimer thresholds showed significant level of agreement (kappa=0.81, p<0.001), high sensitivity (94% and 92.8%), high negative predictive value "NPV" (91.2% and 91.4%), low specificity (12.3% and 15.3%), and low positive predictive value "PPV" (17.5% and 17.8%), respectively. Combination of the age-adjusted D-dimer threshold and RGS at a cut-off of 5 points would provide 100% sensitivity and 61.7% specificity 34.1% PPV, 100% NPV, and 0.87 area under the curve "AUC". At an RGS cutoff <5 points, PE could have been ruled out in more than one-half (1036, 51.5%) of all suspected cases, and would have saved the cost of CTPA. CONCLUSION Conventional and age-adjusted D-dimer tests showed high levels of agreement in the prediction of PE, high sensitivity, and low specificity. RGS has a good performance in PE prediction. Using the revised Geneva score alone rules out PE for more than one-half of all suspected without further imaging.

Abstract
Background: Evidence-based guidelines are needed for effective delivery of home oxygen therapy to appropriate patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD).Methods: The multidisciplinary panel created six research questions using a modified Delphi approach. A systematic review of the literature was completed, and the Grading of Recommendations Assessment, Development and Evaluation approach was used to formulate clinical recommendations.Recommendations: The panel found varying quality and availability of evidence and made the following judgments: 1) strong recommendations for long-term oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe chronic resting hypoxemia, 2) a conditional recommendation against long-term oxygen use in patients with COPD with moderate chronic resting hypoxemia, 3) conditional recommendations for ambulatory oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe exertional hypoxemia, 4) a conditional recommendation for ambulatory liquid-oxygen use in patients who are mobile outside the home and require >3 L/min of continuous-flow oxygen during exertion (very-low-quality evidence), and 5) a recommendation that patients and their caregivers receive education on oxygen equipment and safety (best-practice statement).Conclusions: These guidelines provide the basis for evidence-based use of home oxygen therapy in adults with COPD or ILD but also highlight the need for additional research to guide clinical practice.

Abstract
IMPORTANCE In response to calls to reduce unnecessary diagnostic testing with computed tomographic pulmonary angiography (CTPA) for suspected pulmonary embolism (PE), there have been growing efforts to create and implement decision rules for PE testing. It is unclear if the use of advanced imaging tests for PE has diminished over time. OBJECTIVE To assess the use of advanced imaging tests, including chest computed tomography (CT) (ie, all chest CT except for CTPA), CTPA, and ventilation-perfusion (V/Q) scan, for PE from 2004 to 2016. DESIGN, SETTING, AND PARTICIPANTS Cohort study of adults by age group (18-64 years and ≥65 years) enrolled in 7 US integrated and mixed-model health care systems. Joinpoint regression analysis was used to identify years with statistically significant changes in imaging rates and to calculate average annual percentage change (growth) from 2004 to 2007, 2008 to 2011, and 2012 to 2016. Analyses were conducted between June 11, 2019, and March 18, 2020. MAIN OUTCOMES AND MEASURES Rates of chest CT, CTPA, and V/Q scan by year and age, as well as annual change in rates over time. RESULTS Overall, 3.6 to 4.8 million enrollees were included each year of the study, for a total of 52 343 517 person-years of follow-up data. Adults aged 18 to 64 years accounted for 42 223 712 person-years (80.7%) and those 65 years or older accounted for 10 119 805 person-years (19.3%). Female enrollees accounted for 27 712 571 person-years (52.9%). From 2004 and 2016, chest CT use increased by 66.3% (average annual growth, 4.4% per year), CTPA use increased by 450.0% (average annual growth, 16.3% per year), and V/Q scan use decreased by 47.1% (decreasing by 4.9% per year). The use of CTPA increased most rapidly from 2004 to 2006 (44.6% in those aged 18-64 years and 43.9% in those ≥65 years), with ongoing rapid growth from 2006 to 2010 (annual growth, 19.8% in those aged 18-64 years and 18.3% in those ≥65 years) and persistent but slower growth in the most recent years (annual growth, 4.3% in those aged 18-64 years and 3.0% in those ≥65 years from 2010 to 2016). The use of V/Q scanning decreased steadily since 2004. CONCLUSIONS AND RELEVANCE From 2004 to 2016, rates of chest CT and CTPA for suspected PE continued to increase among adults but at a slower pace in more contemporary years. Efforts to combat overuse have not been completely successful as reflected by ongoing growth, rather than decline, of chest CT use. Whether the observed imaging use was appropriate or was associated with improved patient outcomes is unknown.

Abstract
Application of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) using positive blood cultures (BCs) is a revolution in identification of microorganisms in clinical microbiology laboratories. Although there are several commercial pretreatment protocols they are expensive. Here, we evaluated the performance of a locally produced Bioyong pre-treatment kit for the direct identification of microorganisms in positive BCs by MALDI-TOF MS method. The mocked positive BCs were performed using 200 Thermo aerobic blood culture bottles and 200 aerobic Scenker blood culture bottles. A total of 200 organisms were invovled, including 91 strains of Gram-positive bacteria, 97 strains of Gram-negative bacteria and 12 strains of Candida. The positive BCs were subcultured and identified by classical biochemical Vitek II testing as the gold standard of identification. The Bioyong pre-treatment kit could successfully identify microorganisms in 189 (94.5%) Thermo positive BCs and 189 (94.5%) Scenker positive blood cultures, respectively. In total, 94 (96.9%) Gram-negative bacteria, 86 (94.5%) Gram-positive bacteria and 9 (75.0%) candida isolated from Thermo positive BCs were correctly identified to species level and 95 (97.9%) Gram-negative bacteria, 86 (94.5%) Gram-positive bacteria and 8 (66.7%) candida isolated from Scenker positive BCs were correctly identified to species level. This method provides a rapid, accurate identification of bacteria and Candida within one hour in positive blood cultures. Routine application of this technique will improve the antimicrobial treatment within 24 h among the patients with bacteremia and candidemia.

Abstract
BACKGROUND Use of phosphodiesterase-5 inhibitors (PDE5i) for groups 2 and 3 pulmonary hypertension (PH) is rising nationally, despite guidelines recommending against this low-value practice. Although receiving care across healthcare systems is encouraged to increase veterans' access to specialists critical for PH management, receiving care in 2 systems may increase risk of guideline-discordant prescribing. We sought to identify factors associated with prescribing of PDE5i for group 2/3 PH, particularly, to test the hypothesis that veterans prescribed PDE5i for PH in the community (through Medicare) will have increased risk of subsequently receiving potentially inappropriate treatment in Veterans Health Administration (VA). METHODS AND RESULTS We constructed a retrospective cohort of 34 775 Medicare-eligible veterans with group 2/3 PH by linking national patient-level data from VA and Medicare from 2006 to 2015. We calculated adjusted odds ratios (ORs) of receiving daily PDE5i treatment for PH in VA using multivariable models with facility-specific random effects. In this cohort, 1556 veterans received VA prescriptions for PDE5i treatment for group 2/3 PH. Supporting our primary hypothesis, the variable most strongly associated with PDE5i treatment in VA for group 2/3 PH was prior treatment through Medicare (OR, 6.5 [95% CI, 4.9-8.7]). Other variables strongly associated with increased likelihood of VA treatment included more severe disease as indicated by recent right heart failure (OR, 3.3 [95% CI, 2.8-3.9]) or respiratory failure (OR, 3.7 [95% CI, 3.1-4.4]) and prior right heart catheterization (OR, 3.8 [95% CI, 3.4-4.3]). CONCLUSIONS Our data suggest a missed opportunity to reassess treatment appropriateness when pulmonary hypertension patients seek prescriptions from VA-a relevant finding given policies promoting shared care across VA and community settings. Interventions are needed to reinforce awareness that pulmonary vasodilators are unlikely to benefit group 2/3 pulmonary hypertension patients and may cause harm.

Abstract
Adherence to therapy for pulmonary arterial hypertension is essential to optimize patient outcomes, but data on real-world adherence to different pulmonary arterial hypertension drug classes are limited. This retrospective database analysis evaluated relationships between adherence, hospitalization, and healthcare costs in pulmonary arterial hypertension patients treated with endothelin receptor antagonists or phosphodiesterase type-5 inhibitors. From the IQVIA Adjudicated Health Plan Database, patients with pulmonary arterial hypertension were identified based on diagnostic codes and prescriptions for endothelin receptor antagonists (ambrisentan, bosentan, macitentan) or phosphodiesterase type-5 inhibitors (sildenafil, tadalafil) approved for pulmonary arterial hypertension. Patients were assigned to the class of their most recently initiated (index) pulmonary arterial hypertension therapy between 1 January 2009 and 30 June 2015. Medication adherence was measured by proportion of days covered; patients with proportion of days covered ≥80% were considered adherent. The proportion of adherent patients was higher for endothelin receptor antagonists (571/755; 75.6%) than for phosphodiesterase type-5 inhibitors (970/1578; 61.5%; P < 0.0001). In both groups, hospitalizations declined as proportion of days covered increased. Among adherent patients, those on endothelin receptor antagonists had a significantly lower hospitalization rate than those on phosphodiesterase type-5 inhibitors (23.1% versus 28.5%, P = 0. 0218), fewer hospitalizations (mean (standard deviation) 0.4 (0.8) versus 0.5 (0.9); P = 0.02), and mean hospitalization costs during the six-month post-index ($9510 versus $15,726, P = 0.0318). Increasing adherence reduced hospitalization risk more for endothelin receptor antagonists than for phosphodiesterase type-5 inhibitors (hazard ratio 0.176 versus 0.549, P = 0.001). Rates and numbers of rehospitalizations within 30 days post-discharge were similar between groups. Mean total costs were higher with endothelin receptor antagonists than phosphodiesterase type-5 inhibitors in all patients ($91,328 versus $72,401, P = 0.0003) and in adherent patients ($88,867 versus $56,300, P < 0.0001), driven by higher drug costs.

Abstract
More than 1.5 million adults in the United States use supplemental oxygen for a variety of respiratory disorders to improve their quality of life and prolong survival. This document describes recommendations from a multidisciplinary workshop convened at the ATS International Conference in 2017 with the goal of optimizing home oxygen therapy for adults. Ideal supplemental oxygen therapy is patient-specific, provided by a qualified clinician, includes an individualized prescription and therapeutic education program, and offers oxygen systems that are safe, promote mobility, and treat hypoxemia. Recently, patients and clinicians report a growing number of problems with home oxygen in the United States. Oxygen users experience significant functional, mechanical, and financial problems and a lack of education related to their oxygen equipment-problems that impact their quality of life. Health care providers report a lack of readily accessible resources needed to prescribe oxygen systems correctly and efficiently. Patients with certain lung diseases are affected more than others because of physically unmanageable or inadequate portable systems. Analysis is needed to quantify the unintended impact that the Centers for Medicare and Medicaid Services Competitive Bidding Program has had on patients receiving supplemental oxygen from durable medical equipment providers. Studies using effectiveness and implementation research designs are needed to develop and evaluate new models for patient education, identify effective ways for stakeholders to interface, determine the economic benefit of having respiratory therapists perform in-home education and follow-up testing, and collaborate with technology companies to improve portable oxygen devices. Generation of additional evidence of the benefit of supplemental oxygen across the spectrum of advanced lung diseases and the development of clinical practice guidelines should both be prioritized.

Abstract
RATIONALE Care of patients with pulmonary hypertension is complex. Although pulmonary vasodilators are effective for Group 1 pulmonary hypertension, clinical guidelines and the Choosing Wisely Campaign recommend against routine use for Groups 2 and 3 pulmonary hypertension (the most common types of pulmonary hypertension) because of a lack of benefit, potential for harm, and high cost ($10,000-$13,000 per patient per year treated). Little is known about how these medications are used in practice. OBJECTIVES To determine national patterns of phosphodiesterase-5 inhibitor prescribing for pulmonary hypertension in the Veterans Health Administration. METHODS Retrospective analysis of Veterans prescribed phosphodiesterase-5 inhibitor for pulmonary hypertension between 2005 and 2012 at any Veterans Health Administration site. Patients were identified by presence of an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for pulmonary hypertension and one or more outpatient prescriptions for daily phosphodiesterase-5 inhibitor therapy. We developed and validated, using gold-standard chart abstraction, an International Classification of Diseases, Ninth Revision, Clinical Modification-based algorithm to assign pulmonary hypertension group. Our primary outcome was the proportion of patients who received potentially inappropriate phosphodiesterase-5 inhibitor, as determined by guideline recommendations (Group 1 pulmonary hypertension: appropriate; Groups 2/3: potentially inappropriate; Groups 4/5: uncertain value), among all patients prescribed phosphodiesterase-5 inhibitor for pulmonary hypertension. Secondary outcomes included proportion of treated patients who received guideline-recommended right heart catheterization. RESULTS Among 108,777 Veterans with pulmonary hypertension, 2,790 (2.6% [95% confidence interval, 2.5-2.7%]) received daily phosphodiesterase-5 inhibitor therapy. Among treated patients, 541 (19.4% [95% confidence interval, 18.0-20.9%]) received appropriate treatment, 1,711 (61.3% [95% confidence interval, 59.5-63.1%]) potentially inappropriate treatment, and 358 (12.8% [95% confidence interval, 11.6-14.1%]) treatment of uncertain value. The number of potentially inappropriately treated patients per year increased substantially over the study period (53 in 2005, 748 in 2012). On the basis of chart abstraction in a randomly selected subset of patients treated with phosphodiesterase-5 inhibitor, half (110 of 230, 47.8% [95% confidence interval, 41.3-54.5%]) had documented right heart catheterization to confirm presence or type of pulmonary hypertension. After factoring presence of and data from right heart catheterization into our treatment appropriateness algorithm, only 11.7% (95% confidence interval, 8.0-16.8%) received clearly appropriate treatment. CONCLUSIONS Most Veterans with pulmonary hypertension do not receive phosphodiesterase-5 inhibitor therapy. However, among treated Veterans, almost two-thirds of phosphodiesterase-5 inhibitor prescriptions are inconsistent with pulmonary hypertension guidelines, exposing patients to potential harm and creating a financial burden on the healthcare system. Further study is warranted to clarify the effects of these prescription patterns on pulmonary hypertension outcomes.

Abstract
Two landmark trials conducted more than 35 years ago provided scientific evidence that, under very specific circumstances, long-term oxygen therapy (LTOT) may prolong life. These two trials enrolled 290 patients with chronic obstructive pulmonary disease and severe daytime hypoxemia documented by direct arterial blood gas measurement. From that time, LTOT became a standard of care, and the indications for oxygen therapy expanded to include nocturnal oxygen therapy for isolated nocturnal oxygen desaturation, ambulatory oxygen to correct exercise-induced desaturation, and short-burst oxygen to relieve dyspnea. In most cases, the rationale for broadening the indications for oxygen therapy is that, if hypoxemia exists, correcting it by increasing the FiO2 should help. However, with the exception of LTOT in severely hypoxemic patients with chronic obstructive pulmonary disease, randomized controlled trials of oxygen therapy have failed to demonstrate clinically significant benefits. Also, adherence to LTOT is usually suboptimal. Important areas for future research include improving understanding of the mechanisms of action of supplemental oxygen, the clinical and biochemical predictors of responsiveness to LTOT, the methods for measuring and enhancing adherence to LTOT, and the cost-effectiveness of oxygen therapy. A standardization of terminology to describe the use of supplemental oxygen at home is provided.

Abstract
BACKGROUND Accurate risk stratification of pulmonary embolism (PE) can reduce unnecessary imaging. We investigated the extent to which the American College of Physicians (ACP) guideline for evaluation of patients with suspected PE could be applied to cancer patients in the emergency department of a comprehensive cancer center. MATERIALS AND METHODS Data from cancer patients who underwent CT pulmonary angiography (CTPA) between August 1, 2015, and October 31, 2015, were collected. We assessed each patient's diagnostic workup for its adherence to the ACP guideline in terms of clinical risk stratification and age-adjusted d-dimer level and the degree to which these factors were associated with PE. RESULTS Of the 380 patients identified, 213 (56%) underwent CTPA indicated per the ACP guideline, and 78 (21%) underwent CTPA not indicated per the guideline. Only one of the patients who underwent nonindicated CTPA had a PE. Fifty-seven patients underwent unnecessary d-dimer evaluation, and 71 patients with negative d-dimer test results underwent nonindicated CTPA. PEs were found in 6 of 108 (6%) low-risk patients, 22 of 219 (10%) intermediate-risk patients, and 13 of 53 (25%) high-risk patients. The ACP guideline had negative predictive value of 99% (95% confidence interval: 93%-100%) and sensitivity of 97% (95% confidence interval: 86%-100%) in predicting PE. CONCLUSION The ACP guideline has good sensitivity for detecting PE in cancer patients and thus can be applied in this population. Compliance with the ACP guideline when evaluating cancer patients with suspected PE could reduce the use of unnecessary imaging and laboratory studies.

Abstract
This article reviews four key clinician strategies to improve the care of adult patients receiving supplemental oxygen in the outpatient setting in the United States. The current barriers to adequate oxygen services are substantial and complex and include decreased reimbursement to durable medical equipment (DME) companies; a substantially lower number of available DME suppliers; difficult communication with DME suppliers; rigid patient testing, prescription, and documentation requirements; and unclear patient benefit and adherence. Recent data documenting frequent and varied problems reflect the significant impact of supplemental oxygen therapy on patients and caregivers. Areas where clinicians can improve patient oxygen experiences are highlighted in this review and include understanding Centers for Medicare and Medicaid Services oxygen prescription requirements, matching oxygen equipment to patient needs, providing essential patient education, and understanding mechanisms for patients and clinicians to report unresolved oxygen problems.

Abstract
PURPOSE The aim of this study was to determine rates of and possible reasons for guideline-discordant ordering of CT pulmonary angiography for the evaluation of suspected pulmonary embolism (PE) in the emergency department. METHODS A retrospective review was performed of 212 consecutive encounters (January 6, 2016, to February 25, 2016) with 208 unique patients in the emergency department that resulted in CT pulmonary angiography orders. For each encounter, the revised Geneva score and two versions of the Wells criteria were calculated. Each encounter was then classified using a two-tiered risk stratification method (PE unlikely versus PE likely). Finally, the rate of and possible explanations for guideline-discordant ordering were assessed via in-depth chart review. RESULTS The frequency of guideline-discordant studies ranged from 53 (25%) to 79 (37%), depending on the scoring system used; 46 (22%) of which were guideline discordant under all three scoring systems. Of these, 18 (39%) had at least one patient-specific factor associated with increased risk for PE but not included in the risk stratification scores (eg, travel, thrombophilia). CONCLUSIONS Many of the guideline-discordant orders were placed for patients who presented with evidence-based risk factors for PE that are not included in the risk stratification scores. Therefore, guideline-discordant ordering may indicate that in the presence of these factors, the assessment of risk made by current scoring systems may not align with clinical suspicion.

Abstract
Modern medicine provides almost infinite diagnostic and therapeutic possibilities if compared to the past. As a result, patients undergo a multiplication of tests and therapies, which in turn may trigger further tests, often based on physicians' attitudes or beliefs, which are not always evidence-based. The Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO) adhered to the Choosing Wisely Campaign to promote an informed, evidence-based approach to gastroenterological problems. The aim of this article is to report the five recommendations of the AIGO Choosing Wisely Campaign, and the process used to develop them. The AIGO members' suggestions regarding inappropriate practices/interventions were collected. One hundred and twenty-one items were identified. Among these, five items were selected and five recommendations were developed. The five recommendations developed were: (1) Do not request a fecal occult blood test outside the colorectal cancer screening programme; (2) Do not repeat surveillance colonoscopy for polyps, after a quality colonoscopy, before the interval suggested by the gastroenterologist on the colonoscopy report, or based on the polyp histology report; (3) Do not repeat esophagogastroduodenoscopy in patients with reflux symptoms, with or without hiatal hernia, in the absence of different symptoms or alarm symptoms; (4) Do not repeat abdominal ultrasound in asymptomatic patients with small hepatic haemangiomas (diameter < 3 cm) once the diagnosis has been established conclusively; (5) Do not routinely prescribe proton pump inhibitors within the context of steroid use or long-term in patients with functional dyspepsia. AIGO adhered to the Choosing Wisely Campaign and developed five recommendations. Further studies are needed to assess the impact of these recommendations in clinical practice with regards to clinical outcome and cost-effectiveness.

Abstract
Overuse of computed tomography pulmonary angiography to diagnose pulmonary embolism in people who have only a low pre-test probability of pulmonary embolism has received significant attention in the past. The issue of overdiagnosis of pulmonary embolism, a potential consequence of overtesting, has been less explored. The term “overdiagnosis”, used in a narrow sense, describes a correct (true positive) diagnosis in a person but without any associated harm. The aim of this review is to summarise literature on the topic of overdiagnosis of pulmonary embolism and translate this epidemiological concept into the clinical practice of respiratory professionals. The review concludes that the location of pulmonary embolism at a subsegmental level, rather than whether a diagnosis was made incidentally or following an investigation for suspected pulmonary embolism, is the best predictor for situations in which anticoagulation may not be necessary. In the absence of strong evidence of the optimal management of subsegmental pulmonary embolism, treatment decisions should be made case by case, taking into account the patient's situation and preference. A suggested definition of overdiagnosis of pulmonary embolism: a diagnosis of pulmonary embolism that, if left untreated, would not lead to more harm than if it were treated with anticoagulation therapy, independent of symptomshttp://ow.ly/wgAK30nr5IV

Abstract
BACKGROUND Critically ill patients are at high risk for pulmonary embolism (PE). Specific PE prediction rules have not been validated in this population. The present study assessed the Wells and revised Geneva scoring systems as predictors of PE in critically ill patients. METHODS Pulmonary computed tomographic angiograms (CTAs) performed for suspected PE in critically ill adult patients were retrospectively identified. Wells and revised Geneva scores were calculated based on information from medical records. The reliability of both scores as predictors of PE was determined using receiver operating characteristic (ROC) curve analysis. RESULTS Of 138 patients, 42 (30.4%) were positive for PE based on pulmonary CTA. Mean Wells score was 4.3 (3.5) in patients with PE versus 2.7 (1.9) in patients without PE (P < .001). Revised Geneva score was 5.8 (3.3) versus 5.1 (2.5) in patients with versus without PE (P = .194). According to the Wells and revised Geneva scores, 56 (40.6%) patients and 49 (35.5%) patients, respectively, were considered as low probability for PE. Of those considered as low risk by the Wells score, 15 (26.8%) had filling defects on CTA, including 2 patients with main pulmonary artery embolism. The area under the ROC curve was 0.634 for the Wells score and 0.546 for the revised Geneva score. Wells score >4 had a sensitivity of 40%, specificity of 87%, positive predictive value of 59%, and negative predictive value of 77% to predict risk of PE. CONCLUSIONS In this population of critically ill patients, Wells and revised Geneva scores were not reliable predictors of PE.

Comparison of the age-adjusted and clinical probability-adjusted D-dimer to exclude pulmonary embolism in the ED. Am J Emerg Med 2018; 37:845-850. [PMID: 30077494 DOI: 10.1016/j.ajem.2018.07.053] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 07/23/2018] [Accepted: 07/29/2018] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Diagnosing pulmonary embolism (PE) in the emergency department (ED) can be challenging because its signs and symptoms are non-specific. OBJECTIVE We compared the efficacy and safety of using age-adjusted D-dimer interpretation, clinical probability-adjusted D-dimer interpretation and standard D-dimer approach to exclude PE in ED patients. DESIGN/METHODS We performed a health records review at two emergency departments over a two-year period. We reviewed all cases where patients had a D-dimer ordered to test for PE or underwent CT or VQ scanning for PE. PE was considered to be present during the emergency department visit if PE was diagnosed on CT or VQ (subsegmental level or above), or if the patient was subsequently found to have PE or deep vein thrombosis during the next 30 days. We applied the three D-dimer approaches to the low and moderate probability patients. The primary outcome was exclusion of PE with each rule. Secondary objective was to estimate the negative predictive value (NPV) for each rule. RESULTS 1163 emergency patients were tested for PE and 1075 patients were eligible for inclusion in our analysis. PE was excluded in 70.4% (95% CI 67.6-73.0%), 80.3% (95% CI 77.9-82.6%) and 68.9%; (95% CI 65.7-71.3%) with the age-adjusted, clinical probability-adjusted and standard D-dimer approach. The NPVs were 99.7% (95% CI 99.0-99.9%), 99.1% (95% CI 98.3-99.5%) and 100% (95% CI 99.4-100.0%) respectively. CONCLUSION The clinical probability-adjusted rule appears to exclude PE in a greater proportion of patients, with a very small reduction in the negative predictive value.

Abstract
PURPOSE This study evaluated the long-term effectiveness of mandatory assignment of both a clinical decision rule (CDR) and highly sensitive d-dimer in the evaluation of patients with suspected pulmonary embolism (PE). MATERIALS AND METHODS Institutional guidelines with a CDR and highly sensitive d-dimer were embedded in an order entry menu with mandatory assignment of key components before ordering a CT pulmonary angiogram (CTPA). Data were retrospectively extracted from the electronic health record. RESULTS This was a retrospective review of 1,003 CTPA studies (905 patients, 845 male and 60 female patients, age 63.7 ± 13.5 years). CTPAs were positive for PE in 170 studies (17%), representing an average yield of 15% (year [average]; 2007 [15%], 2008 [18%], 2009 [15%], 2010 [15%], 2011 [17%], 2012 [15%], 2013 [23%]). The increased yield represented efforts of mandatory order entry assignments, educational sessions, and clinical champions. Different d-dimer thresholds with or without age adjustments in combination with the CDR identified about 10% of patients who may have been managed without CTPA. CONCLUSION Mandatory assignment of a CDR and highly sensitive d-dimer clinical decision pathway can be successfully incorporated into an order entry menu and produce a sustained increase in CTPA yield of patients with suspected PE.

Abstract
OBJECTIVES To identify areas for improvement, using a local list of interventions with low diagnostic and therapeutic usefulness for the 5 Related Diagnostic Groups, as well as the 5 main diagnoses most frequently seen in the hospital outpatient clinic. METHOD A literature review method was used, supplemented with a Delphi process with 2 rounds. In the first round, participants in the selection process identified low-value interventions in relation to the most frequently observed diagnoses. In the second round, those interventions with lower usefulness were selected based on their frequency, cost, and risk to the patient. RESULTS Out of a total of 100 recommendations made by 19 scientific societies, 23 received the highest number of votes in the first round. In the second round, 5 recommendations were selected for inpatients and 5 recommendations for outpatients. CONCLUSIONS A simple method is described for developing a local guide to reduce the use of unnecessary medical interventions.

Abstract
Background To identify practices that do not add value, cause harm, or subject patients with chronic obstructive pulmonary disease (COPD) to a level of risk that outweighs possible benefits (overuse). Methods A qualitative approach was applied. First, a multidisciplinary group of healthcare professionals used the Metaplan technique to draft and rank a list of overused procedures as well as self-care practices in patients with stable and exacerbated COPD. Second, in successive consensus-building rounds, description files were created for each "do not do" (DND) recommendation, consisting of a definition, description, quality of supporting evidence for the recommendation, and the indicator used to measure the degree of overuse. The consensus group comprised 6 pulmonologists, 2 general practitioners, 1 nurse, and 1 physiotherapist. Results In total, 16 DND recommendations were made for patients with COPD: 6 for stable COPD, 6 for exacerbated COPD, and 4 concerning self-care. Conclusion Overuse poses a risk for patients and jeopardizes care quality. These 16 DND recommendations for COPD will lower care risks and improve disease management, facilitate communication between physicians and patients, and bolster patient ability to provide self-care.

Qualitative Study to Understand Ordering of CT Angiography to Diagnose Pulmonary Embolism in the Emergency Room Setting. J Am Coll Radiol 2017; 15:1276-1284.

Abstract
PURPOSE To better understand the decision making behind the ordering of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) in the emergency department. METHODS We conducted semistructured interviews with our institution's emergency medicine (EM) providers and radiologists who read CTPAs performed in the emergency department. We employed the Theoretical Domains Framework-a formal, structured approach used to better understand the motivations and beliefs of physicians surrounding a complex medical decision making-to categorize the themes that arose from our interviews. RESULTS EM providers were identified as the main drivers of CTPA ordering. Both EM and radiologist groups perceived the radiologist's role as more limited. Experience- and gestalt-based heuristics were the most important factors driving this decision and more important, in many cases, than established algorithms for CTPA ordering. There were contrasting views on the value of d-dimer in the suspected PE workup, with EM providers finding this test less useful than radiologists. EM provider and radiologist suggestions for improving the appropriateness of CTPA ordering consisted of making this process more arduous and incorporating d-dimer tests and prediction rules into a decision support tool. CONCLUSION EM providers were the main drivers of CTPA ordering, and there was a marginalized role for the radiologist. Experience- and gestalt-based heuristics were the main influencers of CTPA ordering. Our findings suggest that a more nuanced intervention than simply including a d-dimer and a prediction score in each preimaging workup may be necessary to curb overordering of CTPA in patients suspected of PE.

Abstract
OBJECTIVES Hospitalists request 'complete' pulmonary function tests (PFTs), typically comprising of spirometry, diffusion capacity of the lung for carbon monoxide (DLCO) and absolute lung volumes (ALVs), the results of which assist in the management of patients with respiratory disorders. Recently, concerns have been raised about over-requesting of 'complete' PFTs, but there is a paucity of information on the proportion of requests that can be considered clinically inappropriate. This study prospectively evaluated the 'complete' PFTs requested in a hospital service and assessed the impact of medical review of the requests. METHODS A six-month prospective study on requests to two teaching hospital PFT laboratories from non-respiratory doctors was undertaken. Requests at one laboratory underwent review by a respiratory doctor ('intervention laboratory') while requests at the second laboratory were not reviewed ('control laboratory'). The appropriateness of requests was measured against pre-specified criteria. RESULTS PFT requests for 335 subjects were included in the study. In the intervention laboratory, 8 of 110 ALV and 122 of 134 DLCO requests fulfilled pre-specified criteria for appropriate test indications. Fewer ALV (7% vs. 100%, p < 0.001) and DLCO tests (91% vs. 100%, p = 0.031) could have been performed in the intervention laboratory compared to the control laboratory. CONCLUSION A considerable proportion of 'complete' PFT requests from non-respiratory hospital doctors may be unwarranted. Using a simple screening method, the number of unnecessary PFTs could be reduced, resulting in substantial time and cost savings for hospital PFT laboratories.

Abstract
Purpose of review: The purpose of this review is to contribute to the Choosing Wisely Canada campaign and develop a list of 5 items for nephrology health care professionals and patients to re-evaluate based on evidence that they are overused or misused. Sources of information: A working group was formed from the Canadian Society of Nephrology (CSN) Clinical Practice Guidelines Committee. This working group sequentially used a multistage Delphi method, a survey of CSN members, a modified Delphi process, and a comprehensive literature review to determine 10 candidate items representing potentially ineffective care in nephrology. An in-person vote by CSN members at their Annual General Meeting was used to rank each item based on their relevance to and potential impact on patients with kidney disease to derive the final 5 items on the list. Key messages: One hundred thirty-four of 609 (22%) CSN members responded to the survey, from which the CSN working group identified 10 candidate-misused items. Sixty-five CSN members voted on the ranking of these items. The top 5 recommendations selected for the final list were (1) do not initiate erythropoiesis-stimulating agents in patients with chronic kidney disease (CKD) with hemoglobin levels greater than or equal to 100 g/L without symptoms of anemia; (2) do not prescribe nonsteroidal anti-inflammatory drugs for individuals with hypertension or heart failure or CKD of all causes, including diabetes; (3) do not prescribe angiotensin-converting-enzyme inhibitors in combination with angiotensin II receptor blockers for the treatment of hypertension, diabetic nephropathy or heart failure; (4) do not initiate chronic dialysis without ensuring a shared decision-making process between patients, their families, and their nephrology health care team; and (5) do not initiate dialysis in outpatients with CKD category G5-ND in the absence of clinical indications. Limitations: A low survey response rate of both community and academic nephrologists could contribute to sampling bias. However, the purpose of this report is to generate discussion, rather than study practice variation. Implications: These 5 evidence-based recommendations aim to improve outcomes and individualize care for patients with kidney disease, while reducing inefficiencies and preventing harm.

Abstract
Before the introduction of modern imaging techniques and the recent developments in molecular diagnosis, tumor markers (TMs) were among the few available diagnostic tools for the management of cancer patients. Easily obtained from serum or plasma samples, TMs are minimally invasive and convenient, and the associated costs are low. Single TMs were traditionally used but these have come under scrutiny due to their low sensitivity and specificity when used, for example, in a screening setting. However, recent research has shown superior performance using a combination of multiple TMs as a panel for assessment, or as part of validated algorithms that also incorporate other clinical factors. In addition, newer TMs have been discovered that have an increased sensitivity and specificity profile for defined malignancies. The aim of this review is to provide a concise overview of the appropriate uses of both traditional and newer TMs and their roles in diagnosis, prognosis, and the monitoring of patients in current clinical practice. We also look at the future direction of TMs and their integration with other diagnostic modalities and other emerging serum based biomarkers, such as circulating nucleic acids, to ultimately advance diagnostic performance and improve patient management.

Abstract
BACKGROUND Reducing low-value care is a core component of healthcare reforms in many Western countries. A comprehensive and sound set of low-value care measures is needed in order to monitor low-value care use in general and in provider-payer contracts. Our objective was to review the scientific literature on low-value care measurement, aiming to assess the scope and quality of current measures. METHODS A systematic review was performed for the period 2010-2015. We assessed the scope of low-value care recommendations and measures by categorizing them according to the Classification of Health Care Functions. Additionally, we assessed the quality of the measures by 1) analysing their development process and the level of evidence underlying the measures, and 2) analysing the evidence regarding the validity of a selected subset of the measures. RESULTS Our search yielded 292 potentially relevant articles. After screening, we selected 23 articles eligible for review. We obtained 115 low-value care measures, of which 87 were concentrated in the cure sector, 25 in prevention and 3 in long-term care. No measures were found in rehabilitative care and health promotion. We found 62 measures from articles that translated low-value care recommendations into measures, while 53 measures were previously developed by institutions as the National Quality Forum. Three measures were assigned the highest level of evidence, as they were underpinned by both guidelines and literature evidence. Our search yielded no information on coding/criterion validity and construct validity for the included measures. Despite this, most measures were already used in practice. CONCLUSION This systematic review provides insight into the current state of low-value care measures. It shows that more attention is needed for the evidential underpinning and quality of these measures. Clear information about the level of evidence and validity helps to identify measures that truly represent low-value care and are sufficiently qualified to fulfil their aims through quality monitoring and in innovative payer-provider contracts. This will contribute to creating and maintaining the support of providers, payers, policy makers and citizens, who are all aiming to improve value in health care.

Abstract
Purpose To evaluate the variation among U.S. hospitals in overall use and yield of in-hospital computed tomographic (CT) pulmonary angiography (PA) in patients undergoing total hip replacement (THR) or total knee replacement (TKR) surgery. Materials and Methods Patients in the Premier Research Database who underwent elective TKR or THR between 2007 and 2011 were enrolled in this HIPAA-compliant, institutional review board-approved retrospective observational study. The informed consent requirement was waived. Hospitals were categorized into low, medium, and high tertiles of CT PA use to compare baseline patient- and hospital-level characteristics and pulmonary embolism (PE) positivity rates. To further investigate between-hospital variation in CT PA use, a hierarchical logistic regression model that included hospital-specific random effects and fixed patient- and hospital-level effects was used. The intraclass correlation coefficient (ICC) was used to measure the amount of variability in CT PA use attributable to between-hospital variation. Results The cohort included 205 198 patients discharged from 178 hospitals (median of 734.5 patients discharged per hospital; interquartile range, 316-1461 patients) with 3647 CT PA studies (1.8%). The crude frequency of CT PA scans among the hospitals ranged from 0% to 6.2% (median, 1.6%); more than 90% of the hospitals performed CT PA in less than 3% of their patients. The mean hospital-level PE positivity rate was 12.3% (median, 9.1%); there was no significant difference in PE positivity rate across low through high CT PA use tertiles (11.3%, 11.9%, 12.9%, P = .37). After adjustment for hospital- and patient-level factors, the remaining amount of interhospital variation was relatively low (ICC, 9.0%). Conclusion Limited interhospital variation in use and yield of in-hospital CT PA was observed among patients undergoing TKR or THR in the United States. © RSNA, 2016 Online supplemental material is available for this article.

Abstract
OBJECTIVE To determine the prevalence of arterial stump thrombosis (AST) after pulmonary resection surgery for lung cancer and to describe subsequent radiological follow-up and treatment. MATERIAL AND METHODS Observational, descriptive study of AST detected by computerized tomography angiography (CT) using intravenous contrast. Clinical and radiological variables were compared and a survival analysis using Kaplan-Meier curves was performed after dividing patients into 3 groups: patients with AST, patients with pulmonary embolism (PE), and patients without AST or PE. RESULTS Nine cases of AST were detected after a total of 473 surgeries (1.9%), 6 of them in right-sided surgeries (67% of AST cases). Median time to detection after surgery was 11.3 months (interquartile range 2.7-42.2 months), and range 67.5 months (1.4-69.0 months). Statistically significant differences were found only in the number of CTs performed in AST patients compared to those without AST or PE, and in tumor recurrence in PE patients compared to the other 2 groups. No differences were found in baseline or oncological characteristics, nor in the survival analysis. CONCLUSIONS In this series, AST prevalence was low and tended to occur in right-sided surgeries. Detection over time was variable, and unrelated to risk factors previous to surgery, histopathology, and tumor stage or recurrence. AST had no impact on patient survival.

Abstract
Most patients with lung cancer are diagnosed when they present with symptoms, they have advanced stage disease, and curative treatment is no longer an option. An effective screening test has long been desired for early detection with the goal of reducing mortality from lung cancer. Sputum cytology, chest radiography, and computed tomography (CT) scan have been studied as potential screening tests. The National Lung Screening Trial (NLST) demonstrated a 20% reduction in mortality with low-dose CT (LDCT) screening, and guidelines now endorse annual LDCT for those at high risk. Implementation of screening is underway with the desire that the benefits be seen in clinical practice outside of a research study format. Concerns include management of false positives, cost, incidental findings, radiation exposure, and overdiagnosis. Studies continue to evaluate LDCT screening and use of biomarkers in risk assessment and diagnosis in attempt to further improve outcomes for patients with lung cancer.

Abstract
OBJECTIVE To identify Choosing Wisely items for the American Board of Internal Medicine Foundation. METHODS The Society for Healthcare Epidemiology of America (SHEA) elicited potential items from a hospital epidemiology listserv, SHEA committee members, and a SHEA-Infectious Diseases Society of America compendium with SHEA Research Network members ranking items by Delphi method voting. The SHEA Guidelines Committee reviewed the top 10 items for appropriateness for Choosing Wisely. Five final recommendations were approved via individual member vote by committees and the SHEA Board. RESULTS Ninety-six items were proposed by 87 listserv members and 99 SHEA committee members. Top 40 items were ranked by 24 committee members and 64 of 226 SHEA Research Network members. The 5 final recommendations follow: 1. Don't continue antibiotics beyond 72 hours in hospitalized patients unless patient has clear evidence of infection. 2. Avoid invasive devices (including central venous catheters, endotracheal tubes, and urinary catheters)and, if required, use no longer than necessary. They pose a major risk for infections. 3. Don't perform urinalysis, urine culture, blood culture, or Clostridium difficile testing unless patients have signs or symptoms of infection. Tests can be falsely positive leading to overdiagnosis and overtreatment. 4. Do not use antibiotics in patients with recent C. difficile without convincing evidence of need. Antibiotics pose a high risk of C. difficile recurrence. 5. Don't continue surgical prophylactic antibiotics after the patient has left the operating room. Five runner-up recommendations are included. CONCLUSIONS These 5 SHEA Choosing Wisely and 5 runner-up items limit medical overuse. Infect Control Hosp Epidemiol 2016;37:755-760.

Abstract
RATIONALE Annual low-radiation-dose computed tomography (LDCT) screening for lung cancer has been shown to reduce lung cancer mortality among high-risk individuals and is now recommended by multiple organizations. However, LDCT screening is complex, and implementation requires careful planning to ensure benefits outweigh harms. Little guidance has been provided for sites wishing to develop and implement lung cancer screening programs. OBJECTIVES To promote successful implementation of comprehensive LDCT screening programs that are safe, effective, and sustainable. METHODS The American Thoracic Society (ATS) and American College of Chest Physicians (ACCP) convened a committee with expertise in lung cancer screening, pulmonary nodule evaluation, and implementation science. The committee reviewed the evidence from systematic reviews, clinical practice guidelines, surveys, and the experience of early-adopting LDCT screening programs and summarized potential strategies to implement LDCT screening programs successfully. MEASUREMENTS AND MAIN RESULTS We address steps that sites should consider during the main three phases of developing an LDCT screening program: planning, implementation, and maintenance. We present multiple strategies to implement the nine core elements of comprehensive lung cancer screening programs enumerated in a recent ACCP/ATS statement, which will allow sites to select the strategy that best fits with their local context and workflow patterns. Although we do not comment on cost-effectiveness of LDCT screening, we outline the necessary costs associated with starting and sustaining a high-quality LDCT screening program. CONCLUSIONS Following the strategies delineated in this policy statement may help sites to develop comprehensive LDCT screening programs that are safe and effective.

Meeting the milestones. Strategies for including high-value care education in pulmonary and critical care fellowship training. Ann Am Thorac Soc 2016; 12:574-8.

Abstract
Physician decision making is partially responsible for the roughly 30% of U.S. healthcare expenditures that are wasted annually on low-value care. In response to both the widespread public demand for higher-quality care and the cost crisis, payers are transitioning toward value-based payment models whereby physicians are rewarded for high-value, cost-conscious care. Furthermore, to target physicians in training to practice with cost awareness, the Accreditation Council for Graduate Medical Education has created both individual objective milestones and institutional requirements to incorporate quality improvement and cost awareness into fellowship training. Subsequently, some professional medical societies have initiated high-value care educational campaigns, but the overwhelming majority target either medical students or residents in training. Currently, there are few resources available to help guide subspecialty fellowship programs to successfully design durable high-value care curricula. The resource-intensive nature of pulmonary and critical care medicine offers unique opportunities for the specialty to lead in modeling and teaching high-value care. To ensure that fellows graduate with the capability to practice high-value care, we recommend that fellowship programs focus on four major educational domains. These include fostering a value-based culture, providing a robust didactic experience, engaging trainees in process improvement projects, and encouraging scholarship. In doing so, pulmonary and critical care educators can strive to train future physicians who are prepared to provide care that is both high quality and informed by cost awareness.

Abstract
BACKGROUND In Canada, although medical insurance is generally universal, significant differences exist in the provision of home oxygen therapy across the country. OBJECTIVE To systematically compare the terms of reference for home oxygen across Canada, with a focus on the clinical inclusion criteria to the programs. METHODS The authors searched the terms of reference of the 10 Canadian provinces and three territories, focusing on general eligibility criteria for home oxygen (including blood gas criteria, and eligibility criteria for ambulatory and nocturnal oxygen), and compared the eligibility criteria to the widely accepted criteria of the Nocturnal Oxygen Therapy Trial (NOTT) trial, the clinical recommendations of the Canadian Thoracic Society and the results of Cochrane reviews. RESULTS The terms of reference for nine provinces were retrieved. All jurisdictions have similar criteria for long-term oxygen therapy, with slight differences in the thresholds of prescription and the clinical criteria defining 'pulmonary hypertension' or 'cor pulmonale'. The use of oxyhemoglobin saturation as a criterion for funding is inconsistent. All nine provinces fund nocturnal oxygen, all with different clinical criteria. Funding for portable oxygen widely varies across provinces, whether the ambulatory equipment is offered to patients on long-term oxygen therapy or to those who have isolated exercise-induced desaturation. The terms of reimbursement are very heterogeneous. CONCLUSIONS Heterogeneity exists in the criteria for eligibility to home oxygen programs and funding across Canada. Terms of prescription and reimbursement of oxygen are not necessarily supported by available evidence from the current literature in several Canadian jurisdictions.
