Association of Primary Care Physician Supply with Population Mortality in South Korea: A Pooled Cross-Sectional Analysis

BACKGROUND

Primary care physicians perform a comprehensive role by providing continuous, patient-centered, and accessible healthcare and establishing connections with specialized care. However, the association between the supply of primary care physicians and mortality rates in South Korea has not been thoroughly investigated.

METHODS

This study utilized data from 229 si-gun-gu in South Korea from 2016 to 2020. The densities of primary care physicians, physicians in functional primary clinics, specialists in primary care facilities, and active physicians per 100,000 people were independent variables. Age-adjusted all-cause mortality and cause-specific mortality rates per 100,000 individuals were the dependent variables. Negative binomial regression, negative binomial regression with a pseudo-panel approach, and geographically weighted regression were used to analyze the data.

RESULTS

Our study revealed a significant negative association between the density of primary care physicians and all-cause mortality. An increase in a primary care physician per 100,000 population was significantly linked to a 0.11% reduction in all-cause mortality (incidence rate ratio, 0.9989; 95% confidence interval, 0.9983-0.9995). Similar associations have been observed between mortality rates owing to cardiovascular diseases, respiratory tract diseases, and traffic accidents.

CONCLUSION

This study provides evidence that having a higher number of primary care physicians in South Korea is associated with lower mortality rates. Future research should consider better indicators that reflect the quality of primary care to better understand its impact on population health outcomes. These findings emphasize the significance of strengthening primary care in the South Korean healthcare system to improve the overall health and wellbeing.

Few Primary Care Physicians Lead Hospitals, Despite Their Immense Value: Systems Change and Delivery System Evolution Can Reverse This Trend

Primary care physicians (PCPs) inherently offer a tremendous range of skills that would serve them well as chief executive officers in hospitals. Despite their immense value, very few serve in these top posts for a variety of reasons. Making changes in how we train, mentor, and support PCPs throughout their careers can reverse this trend.

Modeling patients' choice between a primary care physician or a diabetes specialist for the management of type-2 diabetes using a bivariate probit analysis

AIMS

To determine the prevalence of type-2 diabetes patients that were initially and currently being treated by primary care physicians (PCPs) or diabetes specialists and assess predictors influencing their choice.

METHODS

This cross-sectional study was conducted in nine Greek primary healthcare units. Patients' choices were modeled using a bivariate probit analysis.

RESULTS

A total of 225 patients participated (84% response rate). Only 15.9% and 11.9% of the respondents acknowledged having chosen a diabetes specialist for their initial or current treatment, respectively. The family history of diabetes in siblings and the screening for diabetic retinopathy during the past year were significantly positively associated with choosing a diabetes specialist (initially p=0.033 or currently p=0.007), and resulted in a statistically significant reduction of the joint probabilities of choosing a PCP by 15.6% and 13.6%, respectively. Younger age (p=0.040), female sex (p=0.017), higher HbA1c (p=0.004), experience of hypoglycemia (p=0.029) and low cardiovascular morbidity index (p=0.016) emerged as important predictors for choosing a diabetes specialist for their treatment.

CONCLUSIONS

Our findings provide a better insight in diabetes patients' choices regarding the category of their treating physicians and their predictors. More studies are required to replicate them and identify patient subpopulations that may favor diabetes specialists' guidance.

Primary care physicians' utilization of type 2 diabetes screening guidelines and referrals to behavioral interventions: a survey-linked retrospective study

OBJECTIVE

To assess primary care physicians' (PCPs) knowledge of type 2 diabetes screening guidelines (American Diabetes Association (ADA) and 2008 US Preventive Services Task Force (USPSTF)), the alignment between their self-reported adherence and actual practice, and how often PCPs recommended diabetes prevention and self-management education programs (DPP/DSME).

RESEARCH DESIGN AND METHODS

An online survey of PCPs to understand knowledge and adherence toward use of USPSTF/ADA guidelines and recommendation of DPP/DSME. Patient data from electronic medical records (EMRs) for each PCP were used to identify rates of screening in eligible patients as per guidelines and the two sources were compared to assess concordance.

RESULTS

Of 305 surveyed physicians, 38% reported use of both guidelines (33% use ADA only, 25% USPSTF only). Approximately one-third of physicians who reported use of USPSTF/ADA guidelines had non-concordant EMR data. Similarly, while most PCPs reported they are 'very likely' to screen patients with risk factors listed in guidelines, for each criterion at least one-fourth (24%) of PCPs survey responses were non-concordant with EMRs. PCPs reported they provide referral to DPP and DSME on average to 45% and 67% of their newly diagnosed patients with pre-diabetes and diabetes, respectively.

CONCLUSION

Findings show disconnect between PCPs' perceptions of adherence to screening guidelines and actual practice, and highlight limited referrals to DPP/DSME programs. More research is needed to understand barriers to guideline consistent screening and uptake of DPP/DSME, particularly in light of recent policy changes such as the linking USPSTF criteria to reimbursement and expected Medicare DPP reimbursement in 2018.
