Access points to different levels of health care over 13 years. Utilization behaviour in a changing health care system. Results of a three-wave cross-sectional series in Austria

Providing health care is a balancing act among human resources, financial pressures and system-intrinsic factors. Understanding the utilization behaviour of primary and secondary care facilities [general practitioners (GPs) vs. specialists, as well as in- and outpatient hospital care] is crucial for a country like Austria, which has free access to all levels of care. The aim of this study was to reassess access point consultations in relation to sociodemographic variables over time. The databases used for this cross-sectional analysis were the Austrian Health Interview Surveys 2006/07, 2014, and 2019, with sample sizes of 15 474, 15 770, and 15 461 persons, respectively. Analyses included patterns of utilization behaviour, multivariable logistic regression models, and diff-in-diff analyses highlighting differences between the observation periods. GP and secondary care consultations increased from 2014 to 2019. While there were fewer GP visits in 2014 than in 2006/07, GP consultation rates grew by 3.2% between 2014 and 2019. Secondary care utilization increased by 5.4%-8.2% between 2006/07 and 2019, with the highest growth in older and less-educated persons. Secondary-level utilization without prior GP visits decreased again in 2019 after peaking in 2014. Utilization of all access points increased over the entire observation period, especially regarding secondary-level care. Higher GP visit rates do not seem to result in a drop in secondary-level consultations. These results emphasize the coordinator role of primary care in ongoing structural health reforms in European countries, such as Austria.
