Overall, the algorithm correctly identified the presence of diabetes in up to 81 percent of patients in two separate datasets. When the algorithm was tested in an additional dataset of patients enrolled from in-person clinics, it correctly identified 82 percent of patients with diabetes.
In the Nature Medicine study, UCSF researchers obtained nearly 3 million PPG recordings from 53,870 patients in the Health eHeart Study who used the Azumio Instant Heart Rate app on the iPhone and reported having been diagnosed with diabetes by a health care provider. This data was used to both develop and validate a deep-learning algorithm to detect the presence of diabetes using smartphone-measured PPG signals.
Among the patients that the algorithm predicted did not have diabetes, 92 to 97 percent indeed did not have the disease across the validation datasets. When this PPG-derived prediction was combined with other easily obtainable patient information, such as age, gender, body mass index and race/ethnicity, predictive performance improved further.
From 2019 to 2020, there was a substantial increase in the proportion of older adults who reported that their health care providers offered telehealth visits. In May 2019, 14% of older adults said that their health care providers offered telehealth visits, compared to 62% in June 2020.
Similarly, the percentage of older adults who had ever participated in a telehealth visit rose sharply from 4% in May 2019 to 30% in June 2020. Of those surveyed in 2020, 6% reported having a telehealth visit prior to March 2020, while 26% reported having a telehealth visit in the period from March to June 2020.
Over the past year, some concerns about telehealth visits decreased among adults age 50–80 whether or not they had a telehealth visit. Older adults’ concerns about privacy in telehealth visits decreased from 49% in May 2019 to 24% in June 2020, and concerns about having difficulty seeing or hearing health care providers in telehealth visits decreased from 39% in May 2019 to 25% in June 2020. Concerns about not feeling personally connected to the health care provider decreased slightly (49% to 45%).
The Best Hospitals Honor Roll highlights 20 hospitals that excel across most or all types of care evaluated by U.S. News. Hospitals received points if they were nationally ranked in the 16 specialties – the more specialties and the higher their rank, the more points they got – and if they were rated high performing in any of the 10 procedures and conditions. The top point-scorers made the Honor Roll.
