Gesundheitskompetenz und Hausarztbindung nicht dringlicher Patientinnen und Patienten in Notaufnahmen: Ergebnisse der PiNo-Studie in Hamburg und Schleswig-Holstein

INTRODUCTION: High utilization of emergency departments by low-acuity patients remains a major challenge for the health care system. Surveys of treatment urgency show that a considerable part of the emergency department population could also be cared for in the outpatient sector. Little is known about the contributing circumstances of non-utilization of outpatient care (despite indication). The expression of health literacy is often called to explain non-urgent use of emergency departments. The extent to which a distinguished commitment to primary care might have a moderating effect is currently not known.

METHODS: The data for this secondary evaluation of a non-urgent emergency department population were taken from the cross-sectional observational study PiNo Nord ("Patients in the emergency departments of hospitals in Northern Germany") (Scherer et al. 2017). In five hospitals in Hamburg and the federal state of Schleswig-Holstein, health literacy and 'intensity of the commitment to a general practitioner' were measured by self-assessment questionnaires (HLS-EU-Q16, F-HaBi). In addition to descriptive data analysis, linear regression was used to estimate the 'intensity of the commitment to a general practitioner' and other somatic, psychological, and sociodemographic characteristics of the population on health literacy.

RESULTS: 548 non-urgent adult patients (mean age 41.5 years, 54.4% men) were included in the evaluation: 55.5% had sufficient, 31.4% problematic and 13.1% inadequate health literacy. 88.3% of the population had a general practitioner. A higher 'intensity of the commitment to a general practitioner', female gender, a higher subjective urgency for treatment, better self-efficacy and better social support were associated with higher health literacy. No associations were found with regard to age, household income, education and migration background, current pain or the degree of physical complaints.

DISCUSSION: The extent of health literacy of a non-urgent sample of the PiNo North study population, responding to the HLS-EU-Q16, was comparable to the health literacy of the general population. Health literacy and intensity of commitment to a general practitioner were positively associated. However, the intensity of GP commitment was rather low. The fact that younger respondents were more likely to provide information about their health literacy and the availability of specialists in urban areas could explain these findings.

CONCLUSION: Improving commitment to primary care physicians could include providing individualized information on how to navigate the health care system. This could make it easier for patients to choose an adequate level of care - and thus have a steering effect on emergency department utilization.
