This document provides guidelines for evaluating patients with pulmonary nodules from the American College of Chest Physicians. It summarizes the guideline objectives, target population, diagnostic and management interventions considered, major outcomes, methodology, recommendations, and validation process. The guideline was developed through a systematic review of literature and expert consensus to provide evidence-based recommendations. It defines solitary pulmonary nodules and provides 12 major recommendations on pre-test probability assessment, imaging tests, PET scanning, discussion of risks/benefits with patients, and tissue diagnosis.

Improving Inclusion/Exclusion Criteria for Clinical TrialsBrook White, PMP
Adherence to inclusion and exclusion criteria is essential to the successful execution of a clinical trial. Deviations from these criteria must be avoided because they can jeopardize scientific integrity, regulatory acceptability, or the safety of subjects in the study. This presentation provides suggestions and advice on formulating inclusion and exclusion criteria to enhance the quality of subject selection, minimize protocol violations, and avoid protocol amendments.

Comparison of Frenotomy Techniques for the Treatment of Ankyloglossia in Chil...JaimePlazasRomn
Objective. To compare the effectiveness of conventional (CF),
laser (LF), and Z-plasty (ZF) frenotomies for the treatment
of ankyloglossia in the pediatric population.
Data Sources. A comprehensive search of PUBMED,
EMBASE, and COCHRANE databases was performed.
Review Methods. Relevant articles were independently assessed
by 2 reviewers according to the Preferred Reporting Items for
Systematic Reviews and Meta-Analysis (PRISMA) guidelines.
Results. Thirty-five articles assessing CF (27 articles), LF (4
articles), ZF (3 articles), and/or rhomboid plasty frenotomy
(1 article) were included. A high level of outcome heterogeneity
prevented pooling of data. All 7 randomized controlled
trials (RCTs) were of low quality. Both CF (5 articles with
589 patients) and LF (2 articles with 78 patients) were independently
shown to reduce maternal nipple pain on a visual
analog or numeric rating scale. There were reports of
improvement with breastfeeding outcomes as assessed on
validated assessment tools for 88% (7/8) of CF articles (588
patients) and 2 LF articles (78 patients). ZF improved
breastfeeding outcomes on subjective maternal reports (1
article with 18 infants) only. One RCT with a high risk of
bias concluded greater speech articulation improvements
with ZF compared to CF. Only minor adverse events were
reported for all frenotomy techniques.
Conclusions. Current literature does not demonstrate a clear
advantage for one frenotomy technique when managing children
with ankyloglossia. Recommendations for future research
are provided to overcome the methodological shortcomings in
the literature. We conclude that all frenotomy techniques are
safe and effective for treating symptomatic ankyloglossia.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Description of Methods Used to Collect/Select the Evidence
Overview
The American College of Chest Physicians (ACCP) chose the Duke University Center for Clinical Health Policy Research
to perform formal systematic reviews of the current evidence in the five new non-small cell lung cancer (NSCLC) topic
areas, as well as to provide a search for the existing guidelines, systematic reviews, and meta-analyses in all of the
topics areas. In addition, the Agency for Healthcare Quality and Research) AHRQ agreed to fund the BlueCross
BlueShield Association Technology Evaluation Center to perform the formal systematic review of literature on small cell
lung cancer (SCLC). The Health Outcomes Research Group of the Department of Epidemiology and Biostatistics at
Memorial Sloan-Kettering Cancer Center conducted a full-scale review of the literature since the first set of guidelines
in the area of screening for lung cancer to assist that particular writing group.
The formal systematic reviews of the five new topic areas were guided by the appropriate chapter editors and their
writing committees, in concert with the Executive Committee of the panel.
The two EPC research teams conducted a variety of systematic computerized bibliographic database searches including
the following: (1) a search for systematic reviews, guidelines, and meta-analyses published since the last ACCP lung
cancer guideline (MEDLINE, The Cochrane Library, National Guidelines Clearinghouse); (2) targeted searches for reviews
in each of five selected treatment sections (solitary pulmonary nodules, stage I and II, stage IIIA, stage IIIB, stage
IV); these searches, run in OVID version of MEDLINE, were performed in July and August 2005 and were limited to
publication years since 1995, English language, and human subjects; and (3) searches related to SCLC are described in
the evidence chapter on SCLC.
Search terms included the medical subject heading terms lung neoplasms (exploded) and bronchial neoplasms for the
lung cancer concept. Each topic search utilized key words specific to the key questions of interest (complete search
strategies are available on request from the authors).
Strategy Specific for the Treatment of Patients with Pulmonary Nodules
To update previous recommendations on the evaluation of patients with pulmonary nodules, guidelines on lung cancer
diagnosis and management that were published between 2002 and May 2005 were identified by a systematic review of
the literature (see the "Availability of Companion Documents" field in this summary for "Methodology for Lung Cancer
Evidence Review and Guidelines Development"). Those guidelines, which include recommendations that are specific to
the treatment of patients with pulmonary nodules, were identified for inclusion in this chapter. Supplemental material
that is appropriate to this topic was obtained by literature search of a computerized database (MEDLINE), as described
in the chapter of these guidelines by Wahidi et al. In addition, we identified articles by searching our own files and by
reviewing reference lists provided by the Thoracic Oncology NetWork of the American College of Chest Physicians
(ACCP). A multidisciplinary writing committee composed of three pulmonologists, two thoracic surgeons, and two
radiologists developed the recommendations and graded the strength of the recommendations and the quality of the
supporting evidence by using a standardized method (see "Methodology for Lung Cancer Evidence Review and Guideline
Development").

Rating Scheme for the Strength of the Evidence
High Randomized controlled trials (RCTs) without important limitations or overwhelming evidence from observational
studies*
Moderate RCTs with important limitations (inconsistent results, methodologic flaws, indirect, or imprecise) or
exceptionally strong evidence from observational studies*
Low or very low Observational studies or case series
*Although the determination of magnitude of the effect based on observational studies is often a matter of judgment, the guideline
developers offer the following suggested rule to assist this decision: a large effect would be a relative risk >2 (risk ratio < 0.5) [which would
justify moving from weak to moderate], and a very large effect is a relative risk > 5 (risk ratio < 0.2) [which would justify moving from weak
to strong]. There is some theoretical justification in the statistical literature for these thresholds (the magnitude of effect that is unlikely or
very unlikely to be due to residual confounding after adjusted analysis). However, once the decision is made, authors should be explicit in
justifying their decisions.
Methods Used to Analyze the Evidence
Review of Published Meta-Analyses
Systematic Review
Description of the Methods Used to Analyze the Evidence
Quality of evidence is scored in three categories with high-quality evidence obtained from randomized controlled trials
(RCTs) without important methodologic limitations based on the study design, the consistency of the results, and the
directness of the evidence. In extraordinary circumstances, significant and consistent evidence from observational
studies could also be ranked as high quality. RCTs with important methodologic limitations or flaws, inconsistent
results, or indirect or imprecise results would be scored as medium quality, as well as exceptionally strong evidence
from observational studies. Other observational studies or case-series data would fall into the low quality of evidence
category. It is the interface of the quality of the evidence and the balance of benefits to harms or burdens that
determines the strength of the recommendation, with a 1A recommendation being the strongest and 2C the weakest.
Methods Used to Formulate the Recommendations
Expert Consensus
Informal Consensus
Description of Methods Used to Formulate the Recommendations
Writing committees studied the evidence and summary tables or reviewed the literature for their assigned topics,
developing their arguments for the recommendations and suggested grading of those recommendations that were put
forth for early drafts. The Executive Committee of the panel, composed of the Chair, Vice-Chair, methodologist, and
both project managers, reviewed drafts of each chapter of the manuscript during the writing process. Sections that
were determined to be potentially overlapping were shared among the appropriate chapter editors, and conference calls
were organized to coordinate the placement of these sections and to confirm that there would be no conflicting
information or recommendations.
A conference of the panel was convened in July 2006, prior to which time all panelists, including representatives from
the invited organizations, were requested to review the complete manuscript and identify recommendations for which
the proposal, wording, or grading were determined to be controversial or could be interpreted as controversial by
others, incorrectly evolved from the evidence, disagreement existed with regard to the proposal or the grading, or
required full panel discussion and further review for any reason. When the panelists who were present were not in
unanimous agreement with the proposed recommendations or the grading of the recommendations, informal group
consensus techniques were employed. After the meeting, a series of conference calls were convened to finish the
discussions and finalize the recommendations. There were a few chapters for which there was insufficient time for full
dialogue during the meeting; in the interest of ensuring that the recommendations followed the evidence, the
conference calls were necessary. This process ensured the "buy-in" of the panelists and was deemed to be a worthwhile
effort.

Description of Method of Guideline Validation
Following final chapter revisions and incorporation of these ultimate recommendations and grading, a concluding review
was conducted by the guideline panel Executive Committee. The guidelines were then submitted for review and
approval to the American College of Chest Physicians Health and Science Policy Committee (ACCP HSP) Committee, as
well as the Thoracic Oncology Network of the college.
Recommendations
Major Recommendations
Definitions for the strength of evidence and recommendation grades (1A-2C) follow the recommendations.
1. In every patient with a solitary pulmonary nodule (SPN), we recommend that clinicians estimate the pretest
probability of malignancy either qualitatively by using their clinical judgment or quantitatively by using a validated
model. Grade of recommendation, 1C
2. In every patient with an SPN that is visible on chest radiography (CXR), we recommend that previous CXRs and
other relevant imaging tests be reviewed. Grade of recommendation, 1C
3. In patients who have an SPN that shows clear evidence of growth on imaging tests, we recommend that tissue
diagnosis should be obtained unless specifically contraindicated. Grade of recommendation, 1C
4. In a patient with an SPN that is stable on imaging tests for at least 2 years, we suggest that no additional
diagnostic evaluation be performed, except for patients with pure ground-glass opacities on CT, for whom a longer
duration of annual follow-up should be considered. Grade of recommendation, 2C
5. In a patient with an SPN that is calcified in a clearly benign pattern, we recommend no additional diagnostic
evaluation. Grade of recommendation, 1C
6. In every patient with an indeterminate SPN that is visible on CXR, we recommend that CT of the chest should be
performed, preferably with thin sections through the nodule. Grade of recommendation, 1C
7. In every patient with an indeterminate SPN that is visible on chest CT, we recommend that previous imaging
tests should be reviewed. Grade of recommendation, 1C
8. In a patient with normal renal function and an indeterminate SPN on CXR or chest CT, we recommend that CT
with dynamic contrast enhancement be considered in centers with experience performing this technique. Grade of
recommendation, 1B
9. In patients with low-to-moderate pretest probability of malignancy (5 to 60%) and an indeterminate SPN that
measures at least 8 to 10 mm in diameter, we recommend that F-18 fluorodeoxyglucose (FDG)-positron emission
tomography (PET) imaging should be performed to characterize the nodule. Grade of recommendation, 1B
10.
In patients with an SPN that has a high pretest probability of malignancy (> 60%), or patients with a
subcentimeter nodule that measures < 8 to 10 mm in diameter, we suggest that FDG-PET not be performed to
characterize the nodule. Grade of recommendation, 2C
11.
In every patient with a SPN, we recommend that clinicians discuss the risks and benefits of alternative
management strategies and elicit patient preferences. Grade of recommendation, 1C
12.
In patients with an indeterminate SPN that measures at least 8 to 10 mm in diameter and who are candidates
for curative treatment, observation with serial CT scans is an acceptable management strategy in the following
circumstances:
l When the clinical probability of malignancy is very low (< 5%)
l When clinical probability is low (< 30 to 40%) and the lesion is not hypermetabolic by FDG-PET or does not
enhance > 15 Hounsfield units (HU) on dynamic contrast CT
l When needle biopsy is nondiagnostic and the lesion is not hypermetabolic by FDG-PET
l When a fully informed patient prefers this nonaggressive management approach
Grade of recommendation, 2C
13.
In patients who have an indeterminate SPN that measures at least 8 to 10 mm in diameter and undergo
observation, we suggest that serial CT scans be repeated at least at 3, 6, 12, and 24 months. Grade of
recommendation, 2C
14.
In patients who have an indeterminate SPN that measures at least 8 to 10 mm in diameter and are candidates
for curative treatment, it is appropriate to perform a transthoracic needle biopsy or bronchoscopy in the following
circumstances:
l When clinical pretest probability and findings on imaging tests are discordant; for example, when the pretest
probability of malignancy is high and the lesion is not hypermetabolic by FDG-PET
l When a benign diagnosis requiring specific medical treatment is suspected
l When a fully informed patient desires proof of a malignant diagnosis before surgery, especially when the risk
of surgical complications is high
In general, we suggest that transthoracic needle biopsy be the first choice for patients with peripheral nodules
unless the procedure is contraindicated or the nodule is inaccessible. We suggest that bronchoscopy be performed

In general, we suggest that transthoracic needle biopsy be the first choice for patients with peripheral nodules
unless the procedure is contraindicated or the nodule is inaccessible. We suggest that bronchoscopy be performed
when an air bronchogram is present or in centers with expertise in newer guided techniques.
Grade of recommendation, 2C
15.
In surgical candidates with an indeterminate SPN that measures at least 8 to 10 mm in diameter, surgical
diagnosis is preferred in most circumstances, including:
l When the clinical probability of malignancy is moderate to high (> 60%)
l When the nodule is hypermetabolic by FDG-PET imaging
l When a fully informed patient prefers undergoing a definitive diagnostic procedure
Grade of recommendation, 1C
16.
In patients with an indeterminate SPN in the peripheral third of the lung and chose surgery, we recommend that
thoracoscopy be performed to obtain a diagnostic wedge resection. Grade of recommendation, 1C
17.
In a patient who chooses surgery with an indeterminate SPN that is not accessible by thoracoscopy,
bronchoscopy, or transthoracic needle aspiration (TTNA), we recommend that a diagnostic thoracotomy be
performed. Grade of recommendation, 1C
18.
In patients who undergo thoracoscopic wedge resection for an SPN that is found to be cancer by frozen section,
we recommend that anatomic resection with systematic mediastinal lymph node sampling or dissection be
performed during the same anesthetic. Grade of recommendation, 1C
19.
In patients who have an SPN who are judged to be marginal candidates for lobectomy, we recommend definitive
treatment by wedge resection/segmentectomy (with systematic lymph node sampling or dissection). Grade of
recommendation, 1B
20.
For the patient who has an SPN and is not a surgical candidate and prefers treatment, we recommend that the
diagnosis of lung cancer be confirmed by biopsy, unless contraindicated. Grade of recommendation, 1C
21.
For the patient who has a malignant SPN and is not a surgical candidate and prefers treatment, we recommend
referral for external-beam radiation or to a clinical trial of an experimental treatment such as stereotactic
radiosurgery or radiofrequency ablation. Grade of recommendation, 2C
22.
For surgical candidates who have subcentimeter nodules and no risk factors for lung cancer, the frequency and
duration of follow-up (preferably with low-dose CT) should depend on the size of the nodule. We suggest the
following:
l Nodules that measure up to 4 mm in diameter not be followed up, but the patient must be fully informed of
the risks and benefits of this approach
l Nodules that measure > 4 to 6 mm be re-evaluated at 12 months without additional follow-up if unchanged
l Nodules that measure > 6 to 8 mm be followed up sometime between 6 and 12 months, and then again
between 18 and 24 months if unchanged
Grade of recommendation, 2C
23.
For surgical candidates who have subcentimeter nodules and one or more risk factors for lung cancer, the
frequency and duration of follow-up (preferably with low-dose CT) should depend on the size of the nodule. We
suggest the following:
l Nodules that measure up to 4 mm in diameter be re-evaluated at 12 months without additional follow-up if
unchanged
l Nodules that measure > 4 to 6 mm should be followed up sometime between 6 and 12 months and then again
between 18 and 24 months if unchanged
l Nodules that measure > 6 to 8 mm be followed up initially sometime between 3 months and 6 months, then
subsequently between 9 and 12 months, and again at 24 months if unchanged.
Grade of recommendation, 2C
24.
For surgical candidates with subcentimeter nodules that display unequivocal evidence of growth during follow-
up, we recommend that definitive tissue diagnosis be obtained by surgical resection, transthoracic needle biopsy, or
bronchoscopy. Grade of recommendation, 1C
25.
For individuals who have subcentimeter nodules and are not candidates for curative treatment, we recommend
limited follow-up (in 12 months) or follow-up when symptoms develop. Grade of recommendation, 1C
26.
In patients who are candidates for curative treatment with a dominant SPN and one or more additional small
nodules, we recommend that each nodule be evaluated individually, as necessary and curative treatment should not
be denied unless there is histopathologic confirmation of metastasis. Grade of recommendation, 1C
27.
In surgical candidates with a solitary pulmonary metastasis, we recommend that pulmonary metastasectomy be
performed if there is no evidence of extrapulmonary malignancy and there is no better available treatment. Grade
of recommendation, 1C
28.
In surgical candidates with an SPN that has been diagnosed as small cell lung cancer (SCLC), we recommend
surgical resection with adjuvant chemotherapy, provided that noninvasive and invasive staging exclude the
presence of regional or distant metastasis. Grade of recommendation, 1C
29. In patients who have an SPN and in whom SCLC is diagnosed intraoperatively, we recommend anatomic
resection (with systematic mediastinal lymph node sampling or dissection) under the same anesthesia when there
is no evidence of nodal involvement and when the patient will tolerate resection. Surgery should be followed by
adjuvant chemotherapy. Grade of recommendation, 1C

Definitions:
Quality of Evidence Scale
High - Randomized controlled trials (RCTs) without important limitations or overwhelming evidence from observational
studies*
Moderate - RCTs with important limitations (inconsistent results, methodologic flaws, indirect, or imprecise) or
exceptionally strong evidence from observational studies*
Low or very low - Observational studies or case series
*Although the determination of magnitude of the effect based on observational studies is often a matter of judgment, the guideline
developers offer the following suggested rule to assist this decision: a large effect would be a relative risk > 2 (risk ratio < 0.5) [which would
justify moving from weak to moderate], and a very large effect is a relative risk > 5 (risk ratio < 0.2) [which would justify moving from weak
to strong]. There is some theoretical justification in the statistical literature for these thresholds (the magnitude of effect that is unlikely or
very unlikely to be due to residual confounding after adjusted analysis). However, once the decision is made, authors should be explicit in
justifying their decisions.

l Recommended management algorithm for patients with subcentimeter pulmonary nodules that measure < 8 mm
in diameter
Evidence Supporting the Recommendations
Type of Evidence Supporting the Recommendations
The type of supporting evidence is identified and graded for each recommendation (see "Major Recommendations").
Benefits/Harms of Implementing the Guideline Recommendations
Potential Benefits
Appropriate diagnosis and management of patients with pulmonary nodules
Potential Harms
Diagnosis
Risks for false-positive and false-negative test results
Complications of Transthoracic Needle Aspiration
Complications include minor pneumothorax in approximately 25% of procedures and major pneumothorax that requires
chest tube drainage in approximately 5% of procedures. Identified risk factors for pneumothorax include smaller lesion
size, deeper location, proximity to fissures, the presence of emphysema, lateral pleural puncture site, and a smaller
angle of entry between the needle and the pleura. Risk factors for chest tube drainage include emphysema, proximity
to fissures, and the need to traverse aerated lung.
Contraindications
Contraindications
Transthoracic needle aspiration is contraindicated in the patient with a single lung. Relative contraindications to this
procedure are the patient with pulmonary hypertension, coagulopathy or a bleeding diathesis, severe chronic
obstructive pulmonary disease (COPD), or vascular malformations.

Implementation of the Guideline
Description of Implementation Strategy
The publication of the Diagnosis and Management of Lung Cancer: ACCP Evidence-Based Clinical Practice Guidelines;
Second Edition in CHEST is the first of two dissemination vehicles. The circulation of the journal is 23,000 subscribers
and libraries, including six translations and distribution to 107 countries. All subscribers received a copy of this full-text
guideline. The American College of Chest Physicians (ACCP) Clinical Resource on Lung Cancer is composed of a printed
publication and an accompanying CD-ROM, containing a quick reference guide for physicians and other health-care
providers, patient-targeted educational materials, and a set of slides for use in educational or clinical contexts. In
addition, the recommendations and grading are personal digital assistant downloadable from the clinical resource. This
product is available for purchase from the ACCP. The patient education materials are accessible free of charge on
www.chestnet.org .
The implementation and translation of evidence-based clinical practice guidelines facilitates knowledge uptake, critical
for practice change, and should ultimately lead to better patient-focused care. The HSP Subcommittee on
Implementation has proposed to collaborate with the Governors, Thoracic Oncology Network, and other groups within
the ACCP to disseminate and implement the guidelines in their local communities. Residency and specialty training
programs are encouraged to use the guidelines in journal clubs and grand rounds. Other organizations that were invited
to send representatives to the final conference and review the proposed drafts were also requested to endorse the
guidelines and market them to their membership through their own communication channels.

Funding for both the evidence review and guideline development was supported by educational grants from
AstraZeneca LP, Bristol-Myers Squibb Company, Eli Lilly and Company, Genentech, and Sanofi-Aventis. Representatives
from these companies were neither granted the right of review, nor were they allowed participation in any portion of
the guideline development process. This precluded participation in either conference calls or conferences. No panel
members or ACCP reviewers were paid any honoraria for their participation in the development and review of these
guidelines.
The ACCP approach to the issue of potential or perceived conflicts of interest established clear firewalls to ensure that
the guideline development process was not influenced by industry sources. This policy is published on the ACCP Web
site at www.chestnet.org . All conflicts of interest within the preceding 5 years were required to be disclosed by all
panelists, including those who did not have writing responsibilities, at all face -to-face meetings, the final conference,
and prior to submission for publication. The most recent of these conflict of interests are documented in this guideline
Supplement. Furthermore, the panel was instructed in this matter, verbally and in writing, prior to the deliberations of
the final conference. Any disclosed memberships on speaker's bureaus, consultant fees, grants and other research
monies, and any fiduciary responsibilities to industry were provided to the full panel in writing at the beginning of the
conference and at submission for publication.
