Can an office practice telephonic response meet the needs of a pandemic?

INTRODUCTION: the H1N1 (subtype hemagglutinin 1 neuraminidase 1) influenza pandemic of 2009 was associated with a large increase in demand for primary care office visits. However, many patients with H1N1 symptoms or exposure could be assessed and treated with telephone protocols. METHODS: specific H1N1 influenza telephone protocols were developed by Mayo Clinic physicians using Centers for Disease Control recommendations. Using symptom calls to a primary care practice in the United States, we captured nurse telephone triage recommendations, telephone antiviral prescriptions, and what callers would have done without telephone advice. We retrospectively analyzed all symptom calls from July 2009 through January 2010. RESULTS: call volume was 5,596 calls monthly during the peak influenza months, which was 56% above the monthly average of 3,595 calls for the nonpeak months (p < 0.001). The calls during October 2009 were 111% over the nonpeak months (p < 0.001). In October 2009, telephone triage nurses gave 412 prescriptions for antivirals accounting for 5.4% of calls and 39% of all telephonic prescriptions for that month. In the peak H1N1 month of October, there were 1,522 callers who intended to stay home for their care. For the same month, triage nurses suggested 3,250 of the callers stay home. For an October 2009 appointment capacity of 35,126 visit slots, a potential 5% capacity was preserved. CONCLUSIONS: a telephone triage solution for the acute demands of influenza H1N1 demonstrated how patients had needs met telephonically while preserving medical access for others.

Improved blood pressure control with a physician-nurse team and home blood pressure measurement.

OBJECTIVE: To assess whether a physician-nurse team model could improve long-term hypertension control rates by active intervention and modification of antihypertensive drug regimens based on home blood pressure (BP) measurements. PATIENTS AND METHODS: This study consisted of patients referred to a hypertension specialty clinic between July 1999 and June 2002 for the evaluation and management of uncontrolled hypertension. Patients were evaluated initially by a physician. A treatment plan was designed and implemented subsequently by a hypertension nurse specialist. Each patient was given an automated digital home BP monitor and requested to provide 42 BP readings taken during 7 days at intervals of 1, 3, 6, 9, and 12 months after dismissal from the clinic. The mean of these weekly values was reviewed by the physician-nurse team, and the treatment regimen was adjusted to achieve a goal BP of less than 135/85 mm Hg. RESULTS: One hundred six consecutively referred patients were enrolled in the study (mean+/-SD age, 64+/-14 years; 58% female; baseline BP, 156+/-16/85+/-11 mm Hg). Ninety-four patients submitted BP data after 1 month, and 78 patients completed the entire 12-month study period. Overall, mean BP decreased to 138+/-17/78+/-8 mm Hg at 1 month and to 131+/-9/75+/-7 mm Hg at 12 months (P<.01 vs baseline). The percentage of patients who achieved BP control to less than 135/85 mm Hg increased from 0% at baseline to 63% at 12 months. Intensification of antihypertensive drug therapy was required, on average, in 24% of patients at each study interval. The mean number of drugs increased from 1.2 at baseline to 2.0 at 12 months (P<.01). CONCLUSION: The use of home BP measurement by a physician-nurse team has the potential to significantly improve long-term hypertension control rates in a geographically dispersed patient population. This model should reduce both cost and inconvenience associated with the treatment of hypertension.
