chronic obstructive pulmonary disease ( copd ) is a progressive yet preventable and treatable disease characterized by incompletely reversible airway obstruction , cough , dyspnea , and phlegm . copd is often associated with tobacco smoking and/or air - borne particulate exposures ( eg , workplace contaminants , biomass smoke , or urban air pollution ) but may also reflect inherited -antitrypsin deficiency and/or idiopathic causes.1,2 current care patterns for copd reflect reactive  rescue care ,  in which health professionals and patients seldom interact except during episodes of acute illness,3 such as exacerbations ( worsening of copd symptoms , which affect patients functioning and require a change in management ) . an exacerbation emergency is often the first presentation of previously undiagnosed but symptomatic copd , which may progress to severe disease before patients seek care,4,5 especially in patients who seldom attend or have insufficient access to primary care . because copd exacerbations are major drivers of copd progression,6 functional deficits,7 health care utilization,8 and cost burden,9 rescue care alone is not optimal for copd.10 acute care for emergent copd exacerbations is insufficient to maintain patients functioning or affect the disease course,10 a punctuated equilibrium in which each successive exacerbation can accelerate respiratory decline.6 proactive diagnosis and management before the first exacerbation occurs can reduce exacerbation incidence and severity and improve outcomes.10 chronic care redesign , to refocus primary practice toward proactive maintenance , can improve care for copd and other ambulatory - care - sensitive conditions ( in which hospitalization rates rise as primary care becomes less accessible and/or adequate).11 proactive , multifactorial copd care  including smoking cessation , vaccinations , physical activity , and maintenance pharmacotherapy to reduce future exacerbations can lessen the physical , care - utilization , and financial burdens of copd.1,2 physicians can uncover unacknowledged symptoms of copd by inquiring about patients reductions in activity as well as overt dyspnea.12 primary care questionnaires and other tools aid identification of candidates for spirometry.13,14 spirometry can be effectively performed in primary care practices to conclusively diagnose copd,15 and is an essential tool for confirming copd and distinguishing it from other respiratory diseases . primary care of copd can benefit from application of wagner s chronic care model ( ccm)16 as implemented in the patient - centered medical home ( pcmh).17 these approaches seek to transform care delivery from a rescue orientation to a planned - care orientation3 and to empower patients and families to collaborate actively with the health care team.18 core aspects of the ccm within a practice include delivery system redesign ( eg , for advanced access to same - day primary care appointments ) , clinical information systems , decision support for clinicians ( such as point - of - care guideline reminders ) , and support for patient self - management.18 additional aspects concern coordination with health care organizations outside the practice ( eg , accountable care organizations integrating specialty and inpatient care with chronic primary care to achieve care coordination and cost savings)19,20 and linkage to community resources.18 the medical home concept has existed since 1967 , when it was developed to coordinate pediatric care for children with special needs.17 more recently the pcmh has been articulated as a broad framework for transforming primary care for patients of all ages . society signatories to the 2007 joint principles of the pcmh17 include the american academy of family practice , american academy of pediatrics , american college of physicians ( acp ) , and american osteopathic association;17 the american medical association subsequently ratified the joint principles.21 through the patient - centered primary care collaborative , a multitude of other professional organizations support the pcmh ; just a few examples include the american colleges of osteopathic family physicians and osteopathic internists , acp , american academies of nurse practitioners and physician assistants , and american board of internal medicine . additionally , in 2010 the acp enunciated principles for the pcmh neighbor,22 a conceptual framework for specialty practices collaborating with the pcmh in patient care . ccm implementations for copd including at least two aspects of wagner s model have been shown to reduce inpatient and emergency utilization.23 successful chronic care requires both practice redesign and patient engagement . third - party disease management programs or other interventions targeted purely to patients are attractive to payers because of perceived cost savings and to practices because of perceived economy of effort . however , chronic care programs that also transform practice organizational culture have greater impact than those requiring the patients to do all the changing.24 collaborative multidisciplinary care teams within a practice and care coordination with inpatient , emergency , and specialty services beyond primary care practice walls are particularly important for improving copd management . this review article aims to provide practical methods and examples for implementing proactive primary care workflows for patients with copd , focusing particularly on the ccm principles of multidisciplinary team collaboration , care coordination , and patient activation . the ccm was developed to free primary care from the  tyranny of the urgent,18,25 in which acute concerns crowd out chronic conditions for priority in time - limited primary care visits . proactive maintenance of chronic disease including copd requires protected resources : multidisciplinary care teams allowing division of labor between acute and chronic care , and scheduled well - care visits supported by previsit planning and providing dedicated chronic care time.3 additionally , since office visits represent a tiny fraction of patients time,25 the ccm strives to activate and educate patients to take care of themselves between visits in the community they live in . planned copd visits should be dedicated solely to copd maintenance and may include individual patients or groups of patients ; visits involving medication management or patient education may be conducted by a nurse or clinical pharmacist using physician - written protocols or standing orders.3 each chronic care visit should have a specific agenda ( eg , spirometry and disease staging , pharmacotherapy initiation , inhaler training , patient education , establishment of smoking cessation pharmacotherapy and support , and physical activity planning ) , so that all aspects of copd management are consciously targeted . copd maintenance in primary care should reflect current copd guidelines.1,2,26 practices can create simple tools ( eg , visit templates and task grids ) to embody guideline essentials in daily workflow ; use of electronic medical records ( emrs ) linking each visit to patients known histories also facilitates opportunistic respiratory follow - up when patients with known or suspected copd visit the practice for other reasons.25 guideline - based management of spirometrically diagnosed stable copd comprises risk reduction , symptomatic and maintenance pharmacotherapy , and pulmonary rehabilitation , as well as additional interventions for severe or very severe disease ( oxygen therapy , surgery , and palliative care ) . the global initiative for obstructive lung disease ( gold ) 20101 and american thoracic society / european respiratory society ( ats / ers ) 2004 guidelines2 address management of stable copd and exacerbations , whereas the 2011 acp/ american college of chest physicians / ats / ers update ( acp / accp / ats / ers)26 focuses on diagnosis and management of stable copd . risk reduction measures appropriate throughout the course of copd include smoking cessation and influenza vaccination for all patients and pneumonia vaccination for senior patients.1,2 pharmacotherapy is generally prescribed according to copd severity and symptoms . short - acting bronchodilators ( gold 2010 specifies short - acting -adrenergic agonists ) may be used for symptom relief at any stage of copd.1,2 maintenance therapy with long - acting antimuscarinic or -adrenergic agents is recommended beginning at moderate disease ( gold 2010),1 for persistent symptoms ( ats / ers 2004),2 or at forced expiratory volume in 1 second ( fev1 ) < 60% predicted ( acp / accp / ats/ ers 2011).26 the latter guidelines also suggest maintenance treatment in symptomatic patients with fev1 between 60% and 80% predicted , while calling for further research in this disease stage.26 inhaled corticosteroids are not preferred as monotherapy,1,26 but may be added to maintenance treatment for more advanced disease and repeated exacerbations.1,2 acp / accp / ats / ers 2011 suggests that clinicians may administer combination therapies to symptomatic patients with fev1 < 60% predicted while weighing potential benefits and harms on a case - by - case basis.26 gold 2010 includes the recently us - approved oral phosphodiesterase inhibitor roflumilast and states that ,  in patients with stage iii : severe copd or stage iv : very severe copd and a history of exacerbations and chronic bronchitis , roflumilast reduces exacerbations treated with oral glucocorticosteroids.1 pulmonary rehabilitation is recommended by gold 20101 to begin in moderate disease , by ats 20042 for patients with respiratory symptoms and functional limitations , and by acp acp / accp / ats / ers 201126 further states that clinicians may consider pulmonary rehabilitation for symptomatic or exercise - limited patients with fev1 > 50% . all three guidelines provide additional therapies for severe and very severe copd : long - term oxygen in hypoxic severe disease , and possible surgical referral in very severe emphysematous copd.1,2,26 gold - recommended long - acting maintenance treatments include the long - acting -adrenergic bronchodilators salmeterol or formoterol , their corticosteroid combinations salmeterol / fluticasone or formoterol / budesonide , and the long - acting antimuscarinic agent tiotropium . two of these maintenance regimens , tiotropium and salmeterol/ fluticasone , are approved by the us food and drug administration to reduce exacerbations of copd . tiotropium is approved  for the once - daily , maintenance treatment of bronchospasm associated with copd27 and  to reduce exacerbations in copd patients,27 and salmeterol / fluticasone is approved  for the twice - daily maintenance treatment of airflow obstruction in patients with copd28 and  to reduce exacerbations of copd in patients with a history of exacerbations.28 indacaterol , a long - acting -adrenergic agonist , received fda approval in 2011  for the long term , once - daily maintenance bronchodilator treatment of airflow obstruction in patients with copd , including chronic bronchitis and/or emphysema.29 tools for proactive primary care of copd include a time - line of care tasks for the first year or more after diagnosis , task grids for division of labor among a multidisciplinary care team , checklists for assuring that the right care takes place at the right time , metrics for tracking improvement in copd care processes and outcomes , and an intrapractice copd patient registry that can be readily developed from meaningful emr use . a basic model of the copd patient journey used in the author s practices can customize a workflow to fit their available resources and patients needs ; core features include spirometric diagnosis when a patient presents with suspected copd , a physician - directed care plan , a designated copd coordinator who handles patient intake , follow - up , and copd registry use by means of the emr , and provision of comprehensive in - person and online patient education within the first year after diagnosis . task assignment across the care team will look different depending on practice size and resources . even a solo practice with one physician and one nurse benefits from regular planned shared reflection and conscious division of labor.30 a large group practice will have available many types of professionals , eg , physicians , medical assistants , registered nurses , nurse practitioners , physician assistants , registered respiratory therapists and physical therapists , dieticians , and/ or clinical pharmacists . successful collaborative care teams assign tasks based on actual skill sets and ensure that every team member works at the highest skill level permitted by licensing . nursing professionals ( from medical assistants through licensed practical nurses , registered nurses , and nurse practitioners ) have many potential touch points with patients , such as autonomous office visits or home visits not requiring a physician , electronic visits , and/or group copd education sessions . an ideal task apportionment amongst the copd team distributes tasks throughout the care team rather than concentrating them upon physicians . additionally , nurses can provide needed follow - up to patients between visits , answering questions , teaching and monitoring inhaler technique , and assisting adherence . a copd coordinator ( the author s practice places a registered nurse in this role ) can handle new copd patient intake , treatment planning under long - range physician guidance , emr use , and health literacy assessment and follow - up comprising self - management teaching , medication adherence assessment , and depression screening . assignment of respiratory care specialists and specially trained registered respiratory therapists or registered nurses to management of copd at baylor university s lung program multiplied rates of spirometry use ( 26% to 100% in internal medicine and 4% to 100% in geriatrics ; p < 0.05 for both ) and documented inhaler training ( 13% to 90% in internal medicine , p < 0.05).31 staff members who themselves are coping with asthma or copd ( or have affected relatives ) make excellent peer - educators and champions for inhaler technique . a practice copd registry facilitates planned care , longitudinal follow - up , and improvement at the level of the practice s copd population . registry contents can be developed by using emr capabilities to identify all patients with diagnosed or suspected copd and to track copd - care - related metrics , such as receipt of spirometry , lung function parameters , guideline - appropriate treatment , physical activity levels , exacerbation incidence / frequency , and resulting care utilization . patients may be allowed to access their own registry information via a secure web portal to facilitate self - management ; patients may even be allowed to enter patient - reported information , eg , on exacerbation triggers and incidence , as - needed inhaler usage levels , and physical activities . web views for care team members within the practice can be configured to allow viewing and management of benchmark indicators for the entire copd patient population . metrics allow the practice to track important processes and outcomes of copd care and provide continuous feedback that permits continuous improvement . plan - do - study - act cycles can be as simple as a solo physician and practice nurse discussing a process improvement , trying it immediately , and discussing the results a week later.30 plan - do - study - act is useful for incremental process improvements;32 however , practice - wide transformation to pcmh methodology often entails multiple interdependent changes exceeding the scope of plan - do - study - act.33 within - practice metrics facilitate process and outcome improvement ; externally visible metrics often inform compensation . currently , copd care has fewer publicly reportable metrics than , for example , diabetes care , placing copd at a disadvantage in pay - for - performance programs.34 ideally , metrics should be selected on the basis of evidence for their contribution to clinical improvement . the diabetes experience indicates that ease of measurement does not necessarily predict impact on patient outcomes.35 possible metrics for copd care include levels of utilization of the copd - population screener13 or other risk - awareness questionnaires , spirometry utilization , treatment guideline adherence ( eg , maintenance inhaler treatment for patients at or beyond moderate copd),1 and primary care follow - up rates promptly after an exacerbation - related emergency room ( er ) or inpatient episode.36 presentation of metrics in chronological order with effective graphics allows immediate visualization of trends and areas needing improvement . the author s practice uses a copd dashboard visualizing patients individual metrics for the patient - accessible web portal and the practice s copd population metrics for the in - clinic professional view . whether metrics measure care processes or the resulting outcomes , all should contribute to the ultimate goal of improving outcomes for patients with copd ( eg , increased activity levels and medication adherence , reduced exacerbation rates , reduced er and hospital visits , and improved follow - up during transitions to and from hospital ) . ccm and pcmh methods invite practices to reconceptualize their workflow to make optimal use of the unique combination of skills in each practice s multidisciplinary care team . this team comprises not only the practice s various professionals but also enlists patients themselves . tools for proactive primary care of copd include a time - line of care tasks for the first year or more after diagnosis , task grids for division of labor among a multidisciplinary care team , checklists for assuring that the right care takes place at the right time , metrics for tracking improvement in copd care processes and outcomes , and an intrapractice copd patient registry that can be readily developed from meaningful emr use . a basic model of the copd patient journey used in the author s work with the educational group practice forum is shown in figure 2 . practices can customize a workflow to fit their available resources and patients needs ;

acp / accp / ats/ ers 2011),26 but pulmonary rehabilitation has been shown to improve respiratory and/or physical functioning in any stage of copd.41 home - based pulmonary rehabilitation has been shown to improve patient - reported dyspnea similarly to in - center pulmonary rehabilitation in patients with moderate to severe copd.42 several long - acting inhaled maintenance therapies , eg , tiotropium,43 salmeterol,44 formoterol,45 budesonide / formoterol,46 salmeterol / fluticasone,47 or tiotropium plus salmeterol / fluticasone,48 have been shown to improve patients ability to exercise , and combining maintenance therapy with formal pulmonary rehabilitation has improved exercise outcomes beyond those obtained with pulmonary rehabilitation alone.43,49 beyond the specific interventions of patient education and pulmonary rehabilitation , clinicians face the challenge of enlisting patients to collaborate actively in managing their copd . where the concept of compliance focuses narrowly on patients following doctors orders to take medications , concordance engages patients in their daily lives and environments  where they live , work , and play  to craft a comprehensive and sustainable lung - friendly lifestyle.50 establishing concordance involves engaging patients where they currently are on the arc of acceptance of their disease . in dealing with a new copd diagnosis , patients often experience stages of grief  denial , anger , bargaining , depression  on their way to acceptance , and their decisions about smoking cessation and other self - care may be complicated by this process . anxiety and reluctance to acknowledge copd - related limitations are related to nonadherence with therapy and poor respiratory and functional coping.51 depression adversely affects coping with copd including therapy adherence ; training in problem - solving skills may improve adherence in elderly copd patients.52 smokers may often admit the risks of smoking in general but tacitly believe that they themselves are not personally susceptible to lung damage . confrontational counseling for smoking cessation , communicating spirometric evidence of airflow limitation , decreased participants denial and increased both their perception of risk and their confidence in their ability to quit ( self - efficacy ) , thus improving cessation rates versus conventional health promotion.53 motivational interviewing is an effective tool for lifestyle change ; it has been shown to help in smoking cessation54 and concurrent depression management,55 to enhance self - management of copd,56 and to improve adherence to medication.57 the most powerful self - management programs incorporate robust interventions , such as cognitive - behavioral therapy and treatment of comorbid depression.23 adherence and persistence with medication are crucial to therapeutic effectiveness . the  brown bag  technique , in which a patient brings all their medications to a primary care appointment and describes how the medications are taken , allows a care team member ( eg , clinical pharmacist ) to monitor adherence and reconcile potential interactions or errors at every visit.58 inhaler technique is important in achieving copd treatment effectiveness ; yet inhaler misuse remains prevalent even among experienced users of respiratory medications . 59 poor maintenance inhaler technique is associated with increased inpatient and emergency care utilization and greater need for systemic steroids and antibiotics . 59 practices need to assign inhaler technique teaching to a specific champion and build it consistently into their copd workflow,60 and patients need to build medication use into their own unique daily lives . routinized medication taking in tandem with a consistent daily activity ( eg , brushing of teeth ) assists adherence.61 in addition to other aspects of the ccm , care coordination and transition management beyond the confines of the primary practice are crucial to successful chronic care for copd . providing all professionals ( within the practice and in other referral or inpatient / er settings ) the same up - to - date information about each patient fosters continuity of care and reduces misunderstandings and rework . referrals ( eg , to pulmonologists , pulmonary function labs , and other specialists such as cardiologists ) are increasingly needed as copd advances ; in a pcmh , processes must be in place for arranging referrals , receiving specialists reports , and following up with patients.62 availability and efficiency of referrals does not necessarily correlate with the size or connectivity of a care organization outside the primary practice , but does depend critically on all appropriate employees having access to the same accurate information about clinicians availability and patients needs . integrated and accountable care organizations form patient - centered medical villages for the pcmh , in which specialty expertise is appropriately accessed by primary physician and patient while supply - sensitive overuse is avoided.19,20 pulmonary rehabilitation may be practice - based , accountable care organization - based , or referred externally . specialist practices that collaborate with referring pcmh primary practices may become pcmh neighbors with processes ensuring appropriate , timely consultations and referrals , sharing information bidirectionally with a pcmh , and determining responsibility for each aspect of collaborative patient care.22 interactions between the specialty clinic and pcmh will vary in duration , intensity , and division of labor . curbside consult  for the primary care physician to ask questions informally , through a formal time - limited consultation to an ongoing shared management arrangement . in certain severe life - limiting diseases the specialist may take on responsibility for principal care . collaboration between a pcmh and specialist neighbor can be facilitated by a care coordination agreement that specifies contents of a patient transition record , defines expectations of information sharing , sets accountability and which practice does what care tasks , and clarifies transition processes for hospitalization and discharge.22 attention to transitions to and from the er or hospital can improve care for patients who experience emergent exacerbations of copd . provision of information from primary care to the er or hospital and proper information sharing within inpatient venues can avoid redundant questioning of patients or failure to act on important health problems.32 in turn , hospitals and ers should alert primary care physicians when patients with known chronic respiratory conditions are admitted.32 an 18-month program of guided primary care for multimorbid elderly patients led by specially trained registered nurses63 achieved significant improvements in coordination of care by making the guided - care nurse responsible for transition arrangements . hospitalization for an exacerbation may be an opportunity to begin guideline - appropriate maintenance treatment.10,64 conversely , sometimes hospitalization may interrupt an existing maintenance regimen for copd . careful medication reconciliation , and preserving or resuming regimens appropriately , is important when patients enter and leave the hospital.32 pcmh methodology can improve primary care follow - up after a copd - related er visit or inpatient stay , which in turn can improve postexacerbation outcomes for patients . a pcmh demonstration project significantly improved the proportion of patients who received follow - up communications from their primary care physician within 3 days after an er visit.36 integrated postdischarge care after hospitalization for an exacerbation , consisting of an individualized plan shared with the primary care team and provision of telephone patient support from a nurse case manager , improved patients recognition and self - care of exacerbations and their medication adherence and inhaler technique.65 recent literature indicates that copd chronic care programs implementing two or more components of the original ccm effectively reduce er and inpatient utilization . advanced primary care access scheduling and robust self - management support were the ccm components showing most evidence for benefit in copd according to a 2007 systematic review.23 multidisciplinary collaborative team care will be implemented differently in practices of different sizes and skill sets ; each primary care practice can devise a team copd care workflow that implements essential tasks of risk awareness , spirometric diagnosis , guideline - based treatment and rehabilitation , and equipping patients for self - management . chronic care for copd must reach beyond the primary care practice into patients lives in the community on the one hand , and into practices linkages with specialty , er , and inpatient care on the other . continuity and communication in care transitions are essential , especially when patients are treated for exacerbations in the hospital or er , to maintain ongoing care regimens and respond to changes in patients respiratory and physical prognosis . primary care practices that expend the effort to transform their approach to chronic diseases , including copd , by using ccm and pcmh concepts , reduce utilization burdens and physical/ psychosocial sequelae more effectively than the default reactive primary care approach . patient - centered chronic care for copd promises to improve health - related quality of life for patients .
current primary care patterns for chronic obstructive pulmonary disease ( copd ) focus on reactive care for acute exacerbations , often neglecting ongoing copd management to the detriment of patient experience and outcomes . 
 proactive diagnosis and ongoing multifactorial copd management , comprising smoking cessation , influenza and pneumonia vaccinations , pulmonary rehabilitation , and symptomatic and maintenance pharmacotherapy according to severity , can significantly improve a patient s health - related quality of life , reduce exacerbations and their consequences , and alleviate the functional , utilization , and financial burden of copd . 
 redesign of primary care according to principles of the chronic care model , which is implemented in the patient - centered medical home , can shift copd management from acute rescue to proactive maintenance . 
 the chronic care model and patient - centered medical home combine delivery system redesign , clinical information systems , decision support , and self - management support within a practice , linked with health care organization and community resources beyond the practice . 
 copd care programs implementing two or more chronic care model components effectively reduce emergency room and inpatient utilization . 
 this review guides primary care practices in improving copd care workflows , highlighting the contributions of multidisciplinary collaborative team care , care coordination , and patient engagement . 
 each primary care practice can devise a copd care workflow addressing risk awareness , spirometric diagnosis , guideline - based treatment and rehabilitation , and self - management support , to improve patient outcomes in copd .
