[Antibiotic consumption surveillance - state of implementation in Munich hospitals : Latest survey by the Munich public health department on the implementation of § 23 Infection protection act].

BACKGROUND: On 4 August 2011 a modification of the infection protection act became law, meaning that antibiotic consumption surveillance and evaluation of data on the local resistance situation became obligatory for hospitals. Four years after the modification of the infection protection act became law, the Munich public health department aimed to evaluate the state of implementation of antibiotic consumption surveillance in Munich hospitals and to ascertain which antibiotic stewardship (ABS) structures have already been established.

METHODS: A questionnaire was sent to Munich hospitals about their antibiotic management structural data and state of implementation of legal requirements.

RESULTS: Only 32 % of the hospitals have qualified ABS-experts available. In 76 % of the hospitals persons responsible for antibiotic consumption surveillance are appointed, while in 12 % persons responsible for antibiotic consumption surveillance are at least partly released from their normal work for this activity. Twenty-one hospitals (21 %) conduct antibiotic consumption surveillance taking into account all antiinfective agents mentioned in the Robert Koch-Institute (RKI) guidelines. Of these, 19 (76 %) did this on basis of World Health Organizations ATC/DDD-system (anatomical therapeutic chemical [ATC] classification system which uses defined daily doses [DDD]). The data on antibiotic consumption is evaluated in 72 % of the hospitals, 68 % take account of the local resistance situation. In 96 %, in-house lists of antiinfectives are available; in 80 %, in-house guidelines for antibiotic treatment are available. Fourty-four percent of the hospitals take part in a national surveillance.

CONCLUSIONS: For the first time data were collected on implementation of antibiotic consumption surveillance in hospitals, which has been required by law since 2011. An incomplete implementation of legal requirements was demonstrated. It was found that structural and personnel prerequisites are often missing, that release from normal work for this additional duty is rarely granted and that the evaluation of data is often either missing or does not correspond to the legal requirements by omitting to take account of the local resistance situation. The hygienic control of hospitals by the public health service was extended by an additional subject. To carry out this very specialized task in a competent way, an ABS-qualification for public health staff is essential from the perspective of the authors.
