Action plans for COPD: strategies to manage exacerbations and improve outcomes

Abstract

COPD is the third-largest killer in the world, and certainly takes a toll on the health care system. Recurrent COPD exacerbations accelerate lung-function decline, worsen mortality, and consume over US$50 billion in health care spending annually. This has led to a tide of payment reforms eliciting interest in strategies reducing preventable COPD exacerbations. In this review, we analyze and discuss the evidence for COPD action plan-based self-management strategies. Although action plans may provide stabilization of acute symptomatology, there are several limitations. These include patient-centered attributes, such as comprehension and adherence, and nonadherence of health care providers to established guidelines. While no single intervention can be expected independently to translate into improved outcomes, structured together within a comprehensive integrated disease-management program, they may provide a robust paradigm.

Introduction

COPD is a leading cause of death worldwide, with an estimated prevalence of almost 10% in adults aged ≥40 years.¹ Approximately 50% of patients with COPD have at least one exacerbation per year, and over 20% are readmitted within 30 days, with a total of nearly 800,000 hospitalizations and US$50 billion in health care costs annually.^2–4 This has led the Centers for Medicare and Medicaid Services to impose financial penalties for hospitals with 30-day readmissions after COPD exacerbations, as part of the Hospital Readmissions Reduction Program. Consequently, it is not surprising that last few years have seen a significant interest in self-management strategies to reduce recurrent exacerbations and hospitalizations. The aim of this review was to examine the utility of COPD action plan-based self-management strategies in acute exacerbations of COPD (AECOPD) and discuss its impact on outcomes.

Action plans: definitions and components

Action plans have been well studied in asthma for decades, and have had more of an established role compared to COPD. A PubMed search (conducted November 2015) for “action plans” along with “asthma” yielded over 400 results compared to 69 results for “COPD”. Traditionally defined as a personalized document generated by health professionals, action plans are intended to promote self-management of exacerbations that may otherwise necessitate acute care, via the patient’s early recognition of an exacerbation and self-initiation of interventions (typically antibiotics and oral corticosteroids). Asthma action plans rely on the variability in symptomatology and peak expiratory flow thought to reflect changes in asthma severity. Although not shown to improve mortality and morbidity, these appear to be protective against severe asthma exacerbations.^5,6 More recent data, however, suggest that asthma action plans may not confer additional benefit to patients already receiving subspecialty care.⁷ COPD action plans on the other hand have been sparsely investigated.

Role of steroids in COPD exacerbations

For decades, oral steroids have played a quintessential role in the management of hospitalized patients with AECOPD. Two previous randomized controlled trials – a Veterans Affairs study⁸ and a similar study⁹ – demonstrated that corticosteroids played an integral role in treating inpatient AECOPD. A recent review by Self et al¹⁰ specifically investigating the role of oral steroids in the setting of COPD action plans found that two^11,12 (of five) published randomized controlled trials containing a total of 933 patients provided evidence of reduced rates of hospitalization by the use of comprehensive COPD action plans, while the others^13–15 showed no differences in rates of rehospitalization. While there was no effect on overall mortality, oral steroids appeared to increase time to next exacerbation.

COPD action plans universally integrate oral steroids in the self-management of AECOPD. However, there is no consensus on the length of corticosteroid therapy. Among hospitalized patients, prior studies have shown that a 2-week therapy course was equivalent or noninferior to extended 6-week tapers of corticosteroids after COPD exacerbations.¹⁶ More recently, a randomized controlled trial enrolled 314 COPD patients that had presented to the emergency room (ER) for acute exacerbations (289 were admitted), and randomized them to 5 days versus 14 days of 40 mg prednisone therapy. The authors reported that a 5-day course of prednisone was noninferior to a 14-day course in terms of likelihood of exacerbation in the subsequent 180 days, time to next exacerbation, and hospital readmissions.¹⁷ A systematic review comparing different durations of oral steroids similarly concluded that a 5-day course might be comparable to a 14-day course for most patients.¹⁸ These data suggest that a 5-day course may be adequate in treating AECOPD. While oral steroids have been shown to be equally efficacious to systemic steroids in hospitalized patients,¹⁹ few studies have compared the efficacy of inhaled corticosteroids to oral steroids.²⁰ Inhaled steroids have not been studied in the setting of an action plan for AECOPD, which typically utilizes short courses of oral steroids.

Role of antibiotics in COPD exacerbations

The majority of patients with AECOPD are treated with antibiotics. However, the efficacy of antibiotics remains less certain for outpatient (versus inpatient) treatment of AECOPD, partly due to the available data being mainly from prospective nonrandomized studies (Table 1). Earlier studies have shown an overall decrease in treatment failures (resolution of symptoms), as well as relapse rates, in patients with AECOPD that received antibiotics when compared to patients that did not receive outpatient antibiotics.^21,22 Also the presence of green (purulent) sputum was found to be 94.4% sensitive and 77% specific for the yield of a high bacterial load and the likelihood of patients to benefit most from antibiotic therapy.²³ A subsequent study by Allegra et al indicated that change in sputum color, especially from yellowish to brownish, was associated with bacterial exacerbations, and their study found an increased yield of Gram-negative and Pseudomonas aeruginosa/Enterobacteriaceae-type organisms.²⁴ In contrast, in a smaller study (n=22), Brusse-Keizer et al found a weak association between bacterial load and sputum color in patients admitted with AECOPD.²⁵

More recently, Llor et al showed in a randomized trial of antibiotics for exacerbations of mild-to-moderate COPD that antibiotic use was associated with a higher chance of clinical cure, as well as longer time to next exacerbation.²⁶ Using data from the placebo arm of this trial, Miravitlles et al evaluated predictors of failure (defined as incomplete resolution, persistence, or worsening of symptoms that require treatment or hospitalization) without antibiotics. They reported that increase in sputum purulence and elevated C-reactive protein concentration was associated with an increased risk of failure without antibiotics.²⁷ Roede et al reported in a population-based cohort study that adding antibiotics to oral steroids was associated with a reduced risk of subsequent exacerbation, especially in patients with recurrent exacerbations, and also reduced risk of all-cause mortality.²⁸

Overall, while these data do not suggest robust efficacy, they do justify the clinical practice of addition of antibiotics for the management of AECOPD, particularly when recurrent and associated with sputum purulence (Table 1). Choosing an optimal antimicrobial agent remains one of the challenges, since a third to two-thirds of exacerbations may be caused by viruses, while bacterial infections appear to trigger about half of AECOPD.^29,30

Self-management using COPD action plans and outcomes

Although COPD action plans have not been formally investigated, several studies have included them as part of a comprehensive-care program (in patients with at least one exacerbation in the preceding year), and reported their effects on reducing ER visits, hospital admissions, and/or overall effect on quality of life (Table 2). A recent Cochrane review concluded that self-management interventions in patients with COPD are associated with improved health-related quality of life and reduction in respiratory-related hospital admissions.³¹

In a prospective randomized controlled trial, Bourbeau et al evaluated the effect of disease-specific self-management intervention on hospitalizations in COPD patients.¹¹ COPD patients with at least one hospitalization for COPD in the previous year were divided into a usual-care group and a self-management group. Patients in the self-management group received comprehensive patient education along, with a customized action plan that consisted of a symptom-monitoring list and prescriptions consisting of antibiotics and oral steroids for 10–14 days to be initiated promptly when symptom changes were noted. The study noted a significant decrease in hospital admissions and exacerbation rates in the self-management group when compared to the usual-care group.

In another randomized controlled trial, Sridhar et al used a hospital database to identify patients admitted for AECOPD in the 4 years prior to the study who had not previously undergone pulmonary rehabilitation (PR).¹³ All patients randomized to the intervention group (versus usual care) underwent PR and self-management education and were given a written COPD action plan. Nurses made monthly telephone calls and quarterly home visits for a period of 2 years and reinforced self-management education. While the authors found no difference in the rate of hospital readmissions, there was an overall reduction in the number of urgent outpatient physician visits, with a number needed to treat of 1.79. Interestingly, there was a significant reduction in COPD-related deaths in the intervention group (one of six deaths) compared to the control group (eight of 12 deaths; P=0.015).

In a retrospective analysis by Sedeno et al, COPD patients were randomly assigned to usual care or to a comprehensive self-management program that included a written action plan with prescription of antibiotics and prednisone for self-administration in the event of an exacerbation, and case-manager support with scheduled phone calls.³² There were a total of 661 exacerbations among the 166 patients studied. While the authors did not find any difference in the frequency of exacerbations between the two groups, there was a significant decrease in exacerbations that led to hospitalizations in the action-plan group (17.2% vs 36.3%, P<0.001). This was associated with a change in patient behavior as part of self-management (more than 50% patients promptly self-treated their exacerbations with prescribed antibiotics and prednisone).

Effing et al prospectively studied the effects of self-management along with an action plan on severity of COPD exacerbations in patients that underwent a mandatory smoking-cessation program prior to randomization.¹⁴ A total of 142 moderate-to-severe COPD patients were randomized to the control group (received self-management education alone) or the intervention group (also received action plan). There was a trend toward fewer exacerbation days and hospital admissions, which was statistically significant only in patients with high exacerbation days per year. Although the frequency of exacerbations was identical in both groups, the authors found a significant reduction in health care contact in the intervention group (P=0.043) that seemed to translate into cost savings.

Rice et al conducted a randomized controlled trial at five Veterans Affairs medical centers, where 743 patients with spirometrically confirmed COPD that were at high risk (hospitalization, home oxygen use, or steroid use in the prior year) of hospital admission were randomized to usual care or a simple disease-management arm.¹² Patients in the disease-management arm received a written action plan and an educational intervention, during which they attended a single 1- to 1.5-hour group-education session conducted by a respiratory therapist. This was followed by monthly phone calls made by the case manager. The study found a significant reduction in the frequency of COPD-related hospitalizations and ER visits (0.82 per patient in usual care versus 0.48 per patient in intervention group, P<0.001). Additionally, the study also reported a statistically significant decrease in incidence of hospitalizations for cardiac or pulmonary conditions other than COPD and for all causes of hospitalizations and ER visits. In contrast, Fan et al performed a randomized controlled trial in 426 COPD patients that had required hospitalization in the prior year and randomized them to usual care or comprehensive-care intervention (comprised of educational intervention and written action plan with prescriptions).¹⁵ The education program run by case managers consisted of four individual 90-minute weekly sessions using an educational booklet, followed by group sessions, and monthly phone calls thereafter that were mainly focused on various aspects of self-management. The study found no difference in the incidence of exacerbations or COPD-related hospitalizations (27% versus 24%, P=0.62). Somewhat surprisingly, however, the study had to be prematurely terminated, due to increased mortality in the intervention group versus usual care (28 overall deaths versus ten, P=0.003; ten COPD-related deaths versus three, P=0.053; intervention group versus usual care, respectively). Of note, although the action plan was designed for patients to initiate treatment within 48 hours of onset of exacerbation symptoms, there was no difference in the actual initiation of treatment between the groups in either prednisone (6.4 days versus 7.7 days, P=0.48) or antibiotics (7 days versus 6.8 days, P=0.84). Interestingly, at a 6-month follow-up after the intervention was stopped, there was no significant difference in deaths (overall or COPD-related) between the groups.

Taken together, these data suggest that the available body of literature on use of action plans in COPD is at best inconclusive. While COPD action plans appear to improve some aspects of COPD exacerbations (reduce severity of exacerbations and/or hospitalizations), they are highly unlikely to have any impact on mortality (Table 2). Unfortunately, the studies lack standardization of action-plan constituents and are flawed with concurrent initiation of one or more self-management strategies, making it nearly impossible to determine which components may have contributed to reported benefit (or lack thereof).

Action plans and self-management strategies may be necessary but not sufficient to improve COPD outcomes

While empowering the patient to better understand the disease process and proactively collaborate with the treating generalist or specialist, self-management strategies still face several challenges limiting their ability to reduce COPD exacerbations and rehospitalizations effectively. When integrated into a multidisciplinary disease-management program, they may be effective in reducing health care utilization.³³ Limitations include patient-centered attributes, such as comprehension and what might be called emotional intelligence, which directly affect self-management abilities,^34–36 as well as other factors that may not be addressed by simplistic strategies (Figure 1).

Patient-centered attributes: psychosocial aspects of COPD

Self-management strategies in COPD often center upon the ability of the patient to identify an exacerbation and trigger the action plan. Therefore, the success of any action plan-based strategy would rely heavily on patient understanding and the ability to actually become effective self-managers. Unfortunately, patients with frequent exacerbations have been reported to have a poor understanding of the term “exacerbation”.³⁷ Just as PR improves exercise capacity but does not seamlessly translate into increased physical activity,^38,39 prescription of an action plan cannot be assumed to translate into timely implementation of the same. Indeed, even in the setting of randomized controlled trials with systematic educational interventions, the majority of COPD patients did not implement self-management strategies as prescribed.^15,40,41 In one trial, only 42% (75 of 150 enrolled patients with AECOPD) were classified as being successful self-managers demonstrating appropriate use of self-management therapies.⁴¹ It seems reasonable to assume that in clinical practice, patient adherence to action plans may be low.

Psychosocial factors may contribute to patient nonadherence toward both pharmacologic and nonpharmacological therapies. Further, exacerbations appear to take a toll on the psychosocial well-being of the patient, and this is underestimated by physicians.³⁷ Negative emotions and lack of psychosocial well-being have been strongly associated with patient nonadherence.^42,43 A recent report associated emotional intelligence (the capacity to understand and manage personal thoughts and feelings positively influencing social well-being) in patients with COPD with self-management abilities independent of age and disease severity.³⁴ Interestingly, it is a trainable skill that may be learned and acquired at any age, and may represent a novel form of rehabilitation complementing existing strategies.

Spirometry underutilization

Physician adherence to recommended use of spirometry remains poor and poses a major challenge, especially since three of every four patients with obstructive lung disease have never had spirometry.^44–46 How do we reconcile literature that suggests both underdiagnosis^47–50 and overdiagnosis^45,51–53 of COPD? It is conceivable that there might in fact be an element of misdiagnosis. This had been well reported in the outpatient setting in patients with symptomatology of obstructive lung disease that were clinically diagnosed as COPD.^54–56 More recently, we have reported misdiagnosis in patients with frequent exacerbations (more than two hospitalizations or ER visits in the prior year) of severe COPD and asthma.⁴⁵ Misdiagnosis was found in 26% (87 of 333) of patients, while another 12% (41 of 333) had obstructive lung diseases other than asthma and COPD. Interestingly, spirometry underutilization was found to be an independent risk factor for misdiagnosis. Uptake of major society guidelines requiring a spirometry confirmation of a diagnosis of COPD is disappointingly low.^44,57 Prescribing empiric therapies with a clinical diagnosis of COPD (without spirometric confirmation) is the norm and not the exception in current clinical practice. In the real world (versus clinical trials), it may be unrealistic to expect self-management strategies designed for COPD to work in a population where the component of “O” (obstruction) and the very diagnosis is in doubt!

Comorbidities

The past decade has improved our understanding of COPD as more of a complex and polygenic disease. Most patients with COPD have major concomitant medical comorbidities that directly or indirectly worsen outcomes.⁵⁸ Up to 94% of patients have at least one comorbid disease, and almost half of all patients have more than three comorbidities.^58,59 High prevalence of obstructive sleep apnea,⁶⁰ pulmonary embolism,⁶¹ and heart failure⁶² has been reported in a quarter to a half of patients with AECOPD. Although there is a distinct urge to diagnose (and treat) a smoker with cough as COPD, smoking-related pulmonary diseases themselves are a large group of distinct diseases, all of which may present with clinical symptomatology of COPD.^63–65 An interesting study investigating the “comorbidome” of COPD evaluated the relationship between 79 comorbidities and risk of death in patients with COPD over a median of 51 months.⁶⁶ They found 12 comorbidities that negatively influenced survival and increased risk of death. Anxiety and depression have been increasingly identified in frequent exacerbators of COPD, and have recently been implicated to have a direct association with exacerbations and health care utilization.^67–69 Patients on long-term oxygen therapy appear to be at risk.⁷⁰ Depression is a known risk factor for noncompliance with medical treatment and poor outcomes.⁴² Unfortunately, data suggest that up to two-thirds of patients with concomitant COPD and depression may not receive treatment for their depression.⁷¹ Overall, these are missed opportunities for improving outcomes by addressing potentially treatable conditions, possibly within a multidisciplinary program.³³

These data beg the question of whether a subset of COPD patients with recurrent hospitalizations have COPD exacerbations or rather exacerbations of symptoms that mimic COPD. Interestingly, a recent investigation using Medicare-claim data from over 26 million inpatient admissions (of which 3.5% were COPD admissions) reported a 30-day COPD readmission rate of 20.2%.² Only half the readmitted COPD patients were admitted for respiratory-related illnesses, with COPD accountable for only 27.6% of readmissions. These data suggest that a subset of patients with COPD exacerbations may not get readmitted for COPD, and further emphasize the possibility of comorbidities playing an important role in recurrent hospitalizations in patients with COPD. Action plan-based self-management strategies are unlikely to be effective when the driving pathology of the exacerbation is indeed an undiagnosed comorbidity.

Phenotypes: asthma–COPD overlap syndrome

Finally, while phenotypic differentiation of asthma and COPD remains challenging, recent data have now well described an asthma–COPD overlap syndrome that may exist in nearly 20% of patients with obstructive lung disease.^72,73 Unfortunately, this phenotype is thought to have increased disease severity and exacerbations than either condition alone.⁷⁴ It is likely that patients with this phenotype would have systematically been excluded from research investigations of asthma as well as COPD, further complicating extrapolation of existing data to this phenotype. Although not well understood, there has recently been an increasing recognition of a distinct phenotype with coexistence of upper lobe-dominant emphysema and pulmonary fibrosis, termed combined pulmonary fibrosis and emphysema.^75,76 While our current understanding of clinically different phenotypes of COPD is growing,^77,78 these patients may need stratified medicine and personalized care above and beyond simplistic self-management strategies.

Conclusion

COPD is a multisystem comorbid syndrome and the third-leading cause of death in the US. A transformational change to holistic strategies may be necessary to improve outcomes for this complex multisystem disease. While there is certainly a role for COPD action plan-based self-management strategies, the burden remains on the physician. An accurate diagnosis of COPD with objective confirmation of airflow obstruction is critical prior to consideration of any self-management. Identifying and addressing concomitant comorbidities cannot be overemphasized. Optimizing psychosocial well-being and mental health may be necessary for improving patient adherence and the success of any interventions. Strategies are more likely to be effective when the focus of care is patient-oriented (versus disease-oriented or COPD-specific). This may require a truly multidisciplinary approach. A well-structured integrated program may provide such a platform to improve outcomes in frequent exacerbators of COPD.
