Abstract

Introduction: This study examined whether patients’ perceptions of their primary care providers’ (PCP) listening frequency were associated with emergency department (ED) utilization, including a comparison to patients without PCPs.

Methods: Data were obtained from the 2015 California Health Interview Survey. Respondents were asked if they had a PCP and how often their PCPs listened, resulting in five groups: patients without a PCP (n=4,407), and patients with a PCP who perceived the PCP’s listening frequency to be never (n=254), sometimes (n=1,282), usually (n=3,440), or always (n=11,651). Multiple linear regression was performed to determine if patient-perceived listening frequency of the PCP was associated with the patient’s number of ED visits in the prior year, adjusting for various demographic, social, and health factors.

Results: Compared to patients without a PCP, patients with a PCP had on average 0.15 more ED visits in a year, highest among those whose PCPs were perceived as listening the least: never=0.55 more visits per year (95% CI: 0.09-1.02, P=.02), sometimes=0.26 (0.01-0.51, P=.04), usually=0.03 (-0.17-0.24, P=.73), and always=0.16 (-0.05-0.36, P=.13). Other significant increases in ED visits were associated with public insurance, African-American race, English proficiency, younger age, self-rated fair-to-poor health, asthma, and hypertension.

Conclusions: Patients who perceived their PCP as listening less frequently had more ED visits than patients whose PCPs were perceived as listening more frequently, and compared to patients without a PCP.

Introduction

There are over 140 million visits annually to emergency departments (ED) in the United States.1 An estimated 13%-27% are considered preventable, costing $4.4 billion annually.2 Research is mixed on whether having a primary care provider (PCP) is associated with increased or decreased ED utilization,3-8 with prior studies showing confounding variables regarding demographics, health, and socioeconomic status.3-5,8

Listening is crucial to the provider-patient relationship.9-12 We hypothesized that patients’ perceptions of provider listening may contribute to the disparate results of previous studies regarding PCP status and ED utilization. To our knowledge, no prior studies have assessed perceived listening and ED utilization. This study examined if ED utilization is associated with patients’ perceptions of how often their PCPs listen, including a comparison to patients without a PCP.

 

Methods

We obtained data from the online 2015 California Health Interview Survey (CHIS)13 and its associated public use data files. CHIS is a large, telephone-based, cross-sectional survey of Californians about various health topics with data freely-accessible online for public analysis. The information was publicly available and subjects were unidentified, therefore institutional review board approval was not required. CHIS screeners obtained informed consent prior to proceeding with interviews.

The survey asked adult participants the question “Do you have a personal doctor or medical provider who is your main provider?” Perceptions of PCP listening frequency were determined by the question: "How often does your doctor or medical provider listen carefully to you?" Responses included “never,” “sometimes,” “usually,” or “always.” The survey asked participants how many times they had used the ED in the past 12 months, ranging from 0 to 5 or more than 5 times. Potential confounding variables were predefined based on previous studies.1,7,14-16 These included age, gender, race/ethnicity, English proficiency, insurance status, income, education, general health status, and health conditions, including asthma, diabetes, heart failure, and hypertension.

We performed statistical analysis using SAS Studio 3.71.17 Baseline characteristics were compared using one-way analysis of variance and χ2 test for continuous and categorical/ordinal variables, respectively. We performed a multiple linear regression using a zero-inflated Poisson distribution was performed to determine if the patient-perceived listening frequency of the PCP was associated with the number of ED visits in the prior year, adjusting for the predefined demographic, socioeconomic, and health factors mentioned.

Results

There were 21,034 respondents divided between five groups: those without a PCP, and, among those with a PCP, four groups of patient-perceived listening frequency of their PCPs. There were significant differences between the groups’ baseline characteristics (Table 1).

Adjusting for demographics, (age, sex, and race), social factors (education, income, English proficiency, and insurance status), and health factors (general health rating, asthma, heart failure, hypertension, and diabetes), respondents with a PCP had on average 0.15 more ED visits in a year. The highest rate of ED visits was among patients whose PCPs were perceived as listening the least: never=0.55 more visits per year (95% CI: 0.09-1.02, P=.02), sometimes=0.26 (0.01- 0.51, P=.04), usually=0.03 (-0.17- 0.24, P=.73), and always=0.16 (-0.05- 0.36, P=.13; Table 2). These results were only significantly different from the non-PCP group at the lower levels of perceived listening. Other significant increases in ED visits were associated with public insurance, African-American race, English proficiency, younger age, self-rated fair-to-poor health, asthma, and hypertension (Table 2).

Conclusions

The purpose of this study was to assess whether the frequency that a patient perceives their primary care provider to listen is associated with ED utilization in the prior year, adjusting for demographics, social factors, and health factors. There were two major conclusions: (1) compared to patients without a PCP, those with a PCP tended to have more ED visits, and (2) there were more ED visits associated with PCPs perceived to listen less, though this was only significant at the lower listening frequencies (never and sometimes).

This study found younger age, African-American race, English proficiency, public insurance, poor-to-fair general health status, asthma, and hypertension were associated with an increased number of ED visits in the prior year. The effects of income, diabetes, heart failure, and education were not statistically significant. This somewhat correlates with other studies suggesting chronic disease leads to increased ED utilization,7,8 however certain chronic diseases were statistically significant while others were not. The diseases included all tended toward increased ED visits. Hypertension had a greater prevalence, thus making it more likely for the results to be significant. As asthma can be highly symptomatic with rapid onset of exacerbations, this may lead patients to be more likely to seek care emergently. We postulate patients with limited English proficiency may be less likely to access the health care system due to language barriers. In some studies, younger patients were found to be more likely to use the ED.7,18 However, other studies described both older and younger patients being more likely to use the ED than middle-aged patients,19 so there may be a bimodal effect that is not well characterized by the linear regression analysis of this study.

The strengths of the study include the large, diverse sample and a multiple linear regression controlling for many confounding variables. Unlike past studies, this study investigated ED utilization relating to a component of the qualitative nature of the patient-PCP relationship. Limitations of this study include unknown generalizability beyond California and potential reporting bias from the telephone survey. Listening is only one facet of patient-PCP relationships and may not reflect the entire quality of the relationship. There may be additional components of the patient-PCP relationship contributing to ED utilization that were not assessed in this study. Provider listening as reported by patients is subject to multiple biases and may not reflect if the provider was actually listening. However, providers often overestimate their own listening skills,20 so these findings may more closely align with the patients’ perspectives. This study was limited by the survey capping ED visits’ maximum at “5 or more,” so coefficient results may be underestimated.

This study provides insight into factors relating to increased ED utilization from a large diverse sample, and suggests that having a PCP perceived as being a less frequent listener is associated with increased ED use. We hope this study inspires PCPs to consider how their patients perceive their listening, and consider strategies to improve their listening skills.21,22
