Use of antibiotics in long-term care facilities for the elderly in Germany – point prevalence as a possible first step for data-based antibiotic stewardship

Abstract

Introduction: In Germany, hospitals, rehabilitation facilities and outpatient surgery facilities are required by law to perform antibiotic-consumption surveillance. Established IT programs are available for recording the defined daily doses. These do not exist for long-term care facilities (LTCFs). Antibiotic stewardship is also recommended for LTCFs. In view of the lack of IT solutions for consumption surveillance, this study investigated whether point prevalence studies could be a suitable basis for a data-based antibiotic stewardship program in LTCFs. Method: In May 2023, 18 elderly-care facilities in Berlin, Germany, participated in a point prevalence survey on antibiotic consumption according to the established HALT (healthcare-associated infections in long-term care facilities) method. The number of residents present and their risk factors (including the use of catheters and antibiotic therapy) were recorded. The results were compared with comparable data from previous surveys in LTCFs in Berlin, Germany as well as with the HALT data for Europe as a whole and for Germany.Results: On the day of the survey, 2040 residents were present, 7.7% of whom bore a urinary catheter and 0.5% a vascular catheter. 0.2% of the residents had a port access, 0.4% a dialysis catheter and one resident (0.05%) a tracheostoma. Twenty-seven (1.3%) residents were receiving an antibiotic on the day of the survey. Of these, 29.6% had a urinary tract catheter. 63.0% of the antibiotics were given for a urinary tract infection, 14.8% for a respiratory tract infection and 11.1% for a wound/soft tissue infection. The overall prevalence of antibiotics was in the range of previous surveys from Germany (1.2–2.4%) and significantly lower than in the Europe-wide HALT survey overall (4.3–4.5%).Discussion: The survey showed low use of antibiotics in the LTCFs in comparison with Europe-wide surveys. The time required was less than 2 hours for a 100-bed facility. Until appropriate IT programs to determine the defined daily doses are also available for LTCFs, such easy-to-perform and standardized point-prevalence surveys – if repeated several times a year – can be a suitable method for recording the use of antibiotics in nursing homes for the elderly.
