The ambulatory care of patients with post-acute sequelae of COVID-19.

backgroundThere is an increasing number of patients that do not make a rapid or full recovery from a SARS-CoV-2 infection, the Coronavirus Disease 2019 (COVID-19) and suffer from the so-called "long-COVID" or post-acute sequelae of COVID-19 (PASC). The long-term implications for health services are expected to be substantial. The objective of this analysis was to estimate the utilization of outpatient services from primary and secondary care. Further, we evaluated the multidisciplinary ambulatory care management of PASC patients in Germany.

methodsAll members of the Physician network "MEDI Baden-Württemberg e.V.", i.e., 1,263 primary care physicians (PCPs) and 1,772 specialists working in secondary care were invited to participate in a questionnaire surveying routine data regarding the general care situation at the physician practice level of patients suffering from PASC. Bivariate analyses were applied to consider potential differences between primary and secondary care.

resultsIn total, 194 physicians participated in this survey (response rates of 9.6% (primary care) and 4.1% (secondary care). On average, each physician treated 31.9 PASC patients. Most PASC patients (61.2%) had three or more long-COVID symptoms. On average, 10.6 PASC patients visited a physicians' practice per quarter. The additional consulting effort for treating PASC patients was 34.1 min (median: 20 min) and higher in primary care. Most PCPs (71.1%) integrated secondary care in the treatment of their PASC patients. Less than half of the PASC patients (42.0%) sought secondary care with a referral from primary care. 5.7 patients visited the physicians' practices per week, who were concerned about suffering from PASC without any following medical confirmation. This caused an average additional effort for the physicians of 17.5 min per visit. There were no differences between rural and urban areas.

conclusionOur results reveal that there is a substantial additional consulting effort for treating PASC patients that is especially high in primary care. The additional consulting effort results from the consultation of a particular high number of patients that are concerned about suffering from PACS without a following medical confirmation. To guarantee a high quality and adequate provision of care for a potentially further increasing number of concerned patients, the ambulatory health services should be strengthened and adequately compensated.
