A Novel Large Scale Integrated Telemonitoring Program for COVID-19.

Introduction: Coronavirus disease 2019 (COVID-19) has forced health care systems to rethink the optimal delivery of health care services and has dramatically increased demand for general medicine providers (internal medicine, family medicine, emergency medicine), while simultaneously reducing demand for many subspecialty services. At Kaiser Permanente, we implemented a program wherein health care providers drawn from multiple disciplines perform daily telemedicine check-ins on COVID-19 patients, allowing us to both maintain social distancing and make use of providers in specialties who otherwise may have had lower in-clinic volumes. Methods: Kaiser Permanente patients testing positive for COVID-19 between March and October 2020 were referred to our program. Physicians and nurses (RNs) were invited to participate in our program and were trained using Microsoft Teams™ meetings. Patients receive daily phone calls by a physician or RN. Select patients receive portable pulse oximeter devices based on standardized criteria incorporating age and comorbidities. When patients are determined to be clinically stable, they are discharged back to their primary care physician for ongoing management. Results: Descriptive results for the virtual home care program (VHCP) are reported through October 2020, though these results do not represent a planned statistical analysis. Forty-two percent of the patients were male, 43% were black, and 30% were Hispanic. The most common comorbidities of patients in our program were obesity (body mass index >30 kg/m2; 35%), followed by hypertension (32%) and diabetes mellitus (19%). Then, 8.2% of patients ultimately required hospital admission. Mortality rate for patients in our program was 1.33%. Discussion: Our program was able to provide virtual care for thousands of COVID-19 positive Kaiser members in the Washington, DC, and Baltimore Metro regions. We did so by utilizing physicians and RNs from specialties experiencing a decrease in clinic volume attributable to the COVID-19 pandemic. The experiences of our program may be valuable to clinicians wishing to establish similar programs of their own.

Lower resource utilization for patients with healed diabetic foot ulcers during participation in a prevention program with foot temperature monitoring.

INTRODUCTION: We assessed the impact of a diabetic foot ulcer prevention program incorporating once-daily foot temperature monitoring on hospitalizations, emergency department and outpatient visits, and rates of diabetic foot ulcer recurrence and lower extremity amputations for patients with recently healed foot ulcers. RESEARCH DESIGN AND METHODS: In this retrospective analysis of real-world data, we enrolled 80 participants with a healed diabetic foot ulcer in a year-long foot ulcer recurrence prevention program. Four outpatient centers within a large integrated healthcare system in the USA contributed to enrollment. We evaluated diabetic foot-related outcomes and associated resource utilization for participants during three periods: the 2 years before the program, the year during the program, and after the program ended. We reported unadjusted resource utilization rates during the program and the periods before and after it. We then adjusted rates of outcomes in each phase using an interrupted time series approach, explicitly controlling for overall trends in resource utilization and recurrence during the three periods. RESULTS: Our unadjusted data showed high initial rates of resource utilization and recurrence before enrollment in the program, followed by lower rates during the program, and higher rates of resource utilization and similar rates of recurrence in the period following the end of the program. The adjusted data showed lower rates of hospitalizations (relative risk reduction (RRR)=0.52; number needed to treat (NNT)=3.4), lower extremity amputations (RRR=0.71; NNT=6.4), and outpatient visits (RRR=0.26; absolute risk reduction (ARR)=3.5) during the program. We also found lower rates of foot ulcer recurrence during the program in the adjusted data, particularly for wounds with infection or greater than superficial depth (RRR=0.91; NNT=4.4). CONCLUSIONS: We observed lower rates of healthcare resource utilization for high-risk participants during enrollment in a diabetic foot prevention program incorporating once-daily foot temperature monitoring.
