16-Year Study Indicates Rising Patient Complexity and Fewer Patients Seen Per Day in Alberta Primary Care

Background and goal: In this study, researchers examined changes over time in characteristics of adults cared for by family physicians from 2004 to 2020 in Alberta, Canada, along with trends in family physicians and their practice patterns for adults over 18 years old.

Study approach: Using linked administrative health data, including physician billing claims and hospital/ambulatory data, the researchers created annual, population-based snapshots from 2004 to 2020 of adults seeing family physicians providing comprehensive care. They tracked patient mix (age, number of chronic conditions, mental health and substance-use conditions) and physician workload (number of clinic days providing primary care, patient contacts per clinic day, and unique adult patients cared for per year).

Main results

The number of female physicians increased from 39% in 2004 to 46.7% in 2020, and graduates trained in low- and middle-income countries rose from 6.3% to 17.2%.

The proportion of individuals aged 61-80 grew from 16.1% to 22.1%, and those with more than five chronic conditions nearly doubled.

There were changes in physician practice over time including decreases in average days worked each year (167 in 2004, 156 in 2020), and the average number of adult visits per clinic day fell from 23 to 20.

Why It Matters: These system level shifts help explain access pressures in primary care and offer a clear signal for health systems to use in workforce planning and resource allocation to meet rising patient complexity.

More low-income adults reported having a usual source of care after the Affordable Care Act

2025-09-22

Research Brief More Low-Income Adults Reported Having a Usual Source of Care After the Affordable Care Act Background and Goal: Before the Affordable Care Act (ACA), uninsured and low-income adults were less likely to have a usual source of care due to cost, coverage, and access barriers. This study evaluated changes in the prevalence of usual sources of care and the reasons for lacking one before and after ACA implementation. Study Approach: Researchers analyzed 2010 to 2017 data from the Medical Expenditure Panel Survey-Household ...

Combining Medicare wellness visits with problem-based visits reduces no-show rates and closes screening gaps

2025-09-22

Original Research Combining Medicare Wellness Visits With Problem-Based Visits Reduces No-Show Rates and Closes Screening Gaps Background and Goal: A recurrent barrier to Medicare annual wellness visits, which provide preventative medicine guidance for older and disabled patients, occurs when patients introduce medical concerns to physicians during these preventative visits. In this study, researchers scheduled combined visits in a single, longer slot with patients’ regularly seen clinicians and used allowed billing rules so both visits could count to see if they could increase the percentage of ...

Penn State Health’s patient-centered quality metric reframing project may serve as a model for presenting future quality metrics

2025-09-22

Innovations in Primary Care Penn State Health’s Patient-Centered Quality Metric Reframing Project May Serve as a Model for Presenting Future Quality Metrics Quality metrics aim to improve patient outcomes by setting evidence-based targets, but many are neither patient centered nor physician centered. A team at Penn State Health’s Department of Family and Community Medicine ran a project across 13 ambulatory clinics to make quality data more meaningful by presenting patient-oriented outcomes in plain, natural language. Using 24 months of electronic health record data, they ...

Heatwaves in US rivers increasing up to four times faster than air heatwaves

2025-09-22

UNIVERSITY PARK, Pa. — As the frequency and intensity of heatwaves increase across the U.S., a similar but more striking phenomenon is occurring in American rivers. Analysis of data from nearly 1,500 sites in the contiguous United States between 1980 and 2022 revealed that heatwaves in rivers are accelerating faster than and lasting nearly twice as long air heatwaves, according to a new study by researchers at Penn State. “Rivers are often thought of as safe and cool havens protected from extreme temperatures,” said Li ...
