Objectives:
The primary objective of this study was to determine the effect of a pharmacist-provided spirometry service within a federally qualified health center on the percentage of spirometry referrals completed with results reviewed by the ordering provider. Secondary objectives evaluated differences between internal and external referrals, medication recommendations made by the pharmacist, and revenue brought in by the service.
Methods:
Chart reviews were completed to determine the referral completion rates between patients who received a spirometry referral before (December 2014-September 2015) and after (January 2016-October 2016) the implementation of the pharmacy-provided spirometry service. Chart reviews were also used to determine the number and completion rate among referrals for internal and external services in the postimplementation time frame. Chart reviews also assessed medication recommendations made by the pharmacist.
Results:
The results demonstrate an increase in referral completion rate from 38.1% to 47.0% ( P = .08) between the pre- and postimplementation time frames. In the postimplementation time frame, there was a statistically significant difference in the percentage of referrals completed between in-house referrals and external referrals (70.0% and 40.9%, respectively, P = .0004). Comparing clinics with and without the spirometry service, there was a statistically significant difference in the total number of spirometry referrals (1.13% and 0.59%, respectively, P < .0001) and the percent of referrals completed (0.55% and 0.27%, respectively, P = .0002).
Conclusion:
The results suggest that offering spirometry within the primary care setting helps to increase the rate of completed spirometry tests with results available to the primary care provider. Additionally, the results show that there is an increased completion rate in patients who receive an internal spirometry referral, which may be due to reduced barriers in obtaining this testing. Overall, these results demonstrate that providing spirometry in the primary care setting helps to increase spirometry results obtained and could be beneficial in other primary care settings.

Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
