This study was performed retrospectively, increasing the potential of missing data, especially from outside the VA health care system. Patients were not randomly assigned to rural or urban clinics, so differences in patient characteristics could exist. Alcohol and addictive disorders were more common in urban patients, which might affect adherence to prescribed medications. In addition, lower rate of obstructive sleep apnea was found in the rural population, which has been linked to increased airway inflammation and COPD exacerbations resulting in hospitalization.32,33 Mortality was not assessed as all patients were alive and seen in clinic at time of enrollment.
The authors were not able to record a patients’ residence in a long-term care facility or institutionalization, use of home care, or palliative care services due to limitations in the EMR system. Whether patients received comanaged primary care or underwent pulmonary rehabilitation could not be obtained from the EMR. Most patients never had lung volumes or diffusion capacity and thus were not included. The authors could not report whether inhaler therapy was appropriate compared with the Global Initiative for Chronic Obstructive Lund Disease(GOLD)severity score because most of the spirometry was done at a discordant time to when inhaler therapy was assessed, and new GOLD guidelines include patient symptoms that were not reliably recorded in the EMR. Last, the authors had hoped to include smoking status and cessation practices as part of the quality measures, but due to significant variability in patients’ documented smoking status in the same period, the data were deemed unreliable.
Conclusion
No disparities were found between rural and urban clinics in the quality of health care for patients with COPD in the MVAHCS except that fewer rural patients had prior spirometry; a difference that is likely due to the fact that only recently has spirometry been implemented in the MVAHCS rural clinics. Overall the quality of COPD care was high and above the previously reported rates. Further larger studies of rural and urban quality of health care for patients with COPD are needed in other VA and non-VA systems to determine whether disparities exist and whether they are associated with clinical outcomes, including ED visits, hospitalizations, and mortality.
