UC DAVIS (US) — Patients with greater access to three specific attributes of high-quality primary care have a reduced risk of death, research shows.
A new study published in the Annals of Family Medicine is the first to link comprehensiveness, a patient-centered approach, and extended office hours to lower mortality.
“There are a number of studies that found lower mortality risk in geographic areas with relatively high concentrations of primary-care physicians, but these associations were not necessarily applicable to individual patients within those geographic areas,” says lead author Anthony Jerant, professor of family and community medicine at the University of California, Davis.
“These studies also defined ‘primary care’ by physician specialty rather than by specific aspects of health care. We wanted to know if patients who reported having access to critical elements of primary care had lower mortality risk.”
To conduct the study, Jerant and colleagues used data from the 2000-05 Medical Expenditure Panel Surveys—large-scale surveys of people living in the U.S. and their health and health care. The study used data for 52,241 respondents aged 18 to 90 years for whom mortality information was available and who had one particular doctor’s office or clinic they visited for health information and treatment.
The researchers analyzed respondents’ reported access to three primary health-care attributes:
- Comprehensiveness, which includes the provision of care for new health problems, preventive care, and referrals to other health-care professionals
- The availability of evening and weekend office hours
- Patient-centeredness, meaning that their health-care provider listened to and sought the patient’s advice when deciding on treatments
The researchers found that after adjusting for age, health status, weight, tobacco use, and other health characteristics, greater reported access to the primary-care attributes was associated with significantly lower mortality (hazard ratio 0.79) during up to six years of follow-up.
“Our findings suggest that ongoing efforts to provide all Americans with a ‘medical home’ offering the primary-care attributes we studied could yield major public health benefits,” says Jerant, referring to the national movement to ensure access to patient-centered, comprehensive, and continuously available primary-care services.
Racial/ethnic minorities, poorer and less educated individuals, and those lacking health insurance reported significantly lower access to the primary-care attributes than others, the study reports.
“Although the wider adoption of primary care attributes may have promise for mitigating health disparities, interventions to promote equitable access to such attributes may be required to fulfill this promise.”
