Electronic health records and improved nursing management of chronic obstructive pulmonary disease

The important role of primary care providers in the detection of alpha-1 antitrypsin deficiency

OBJECTIVE

Alpha-1 antitrypsin deficiency (AATD) is an underrecognized genetic disorder that can cause chronic obstructive pulmonary disease (COPD) and liver cirrhosis, two clinical conditions commonly seen by primary care physicians. AATD is estimated to affect 1/4000-1/5000 people in the United States and 1-2% of all COPD cases.

METHODS

PubMed was searched for relevant articles using AAT/AATD-related terms.

RESULTS

Unfortunately, <10% of symptomatic individuals have been properly diagnosed primarily due to the underdiagnosis of COPD and the lack of awareness of AATD as a possible underlying cause. Because primary care providers are most likely to be the first to encounter symptomatic individuals, their role in the identification and early diagnosis of AATD patients is instrumental, particularly since therapy to slow lung disease progression is available. The diagnosis of AATD is laboratory-based rather than clinical. Testing for AATD should be part of the reflex testing that follows any COPD diagnosis or unexplained liver disease and can be performed by determining the AAT phenotype or genotype along with serum AAT levels. Both nonpharmacological and pharmacological approaches are recommended for treatment of lung disease, including smoking cessation, bronchodilators or supplemental oxygen as needed. Specific augmentation of AAT levels with regular purified AAT infusions has been found to slow lung function decline and emphysema progression in patients with moderate airflow obstruction and severely low serum AAT levels.

CONCLUSIONS

Improving primary care provider awareness and promoting regular reflex testing all COPD patients for AATD may significantly improve the care of COPD patients.

Coordination of care for patients with COPD: Clinical points of interest

The management of care of chronic obstructive pulmonary disease improved over the last years but is still very complex. Both over- and underdiagnosis are often reported and misclassification of disease severity is common. Differentiating between chronic obstructive pulmonary disease, asthma and asthma-chronic obstructive pulmonary disease overlap syndrome remains difficult. Much is known about the effectiveness of treatment approaches in chronic obstructive pulmonary disease, but patients are often not treated according to the guidelines, and we need more evidence on effectiveness in phenotypes of chronic obstructive pulmonary disease. Care coordination is of great importance and can help to further improve care for chronic obstructive pulmonary disease patients. Pulmonary rehabilitation and self-management are considered important aspects of chronic obstructive pulmonary disease care. In our opinion, there is a major role for eHealth to improve coordination of care of chronic obstructive pulmonary disease.
