title: [Highly resistant pathogens in patients with diabetic foot syndrome with special reference to methicillin-resistant Staphylococcus aureus infections].
abstract: OBJECTIVE
  Patients with diabetic foot infection (DFI) have a high rate of infection, up to 40%, with methicillin-resistant Staph. aureus (MRSA). Having noticed a definite increase of such patients in our special unit, we initiated a drastic change of hygienic measures and here report the results.
  
  
  METHODS
  788 patients with DFI (mean age 67.3 [32-90] years, 62% males) were admitted between 1.1.1999 and 31.7.2000. Before 31.7.1999, the following hygienic measures had been in place: cohort isolation, protective closing, implementation of general hygienic rules. Since 1.8.1999, modified measures have been undertaken: primary single-patient isolation, concentration in one ward of all patients with MRSA, medical care only by trained personnel, admission of patients only after microbiological results were known or primary solitary isolation. Algorithms were used for the transmission of all necessary information.
  
  
  RESULTS
  MRSA was demonstrated in 64 patients. The number of infections during the hospital stay, before and after the change of hygienic measures were 9 (27%) and 2 patients (8%), respectively. The sites of MRSA colonisation and proven eradication were: nasopharynx only, 3 with 67% eradication; MRSA in a wound, 25 with 28% eradication. In comparison to the yearly statistic on wound healing in DFI 1999 (n=613) the following results are shown (patients with MRSA in brackets): healing rate with conservative treatment 61.5% (20%), minor-amputation 30.5% (52%), major-amputation 4.5% (22%), death 3.5% (6%).
  
  
  CONCLUSIONS
  The rate of new infections were dramatically reduced by changing the hygienic measures. The rate of successful sanitation was unsatisfactoy. Patients with MRSA showed markedly poorer treatment results in respect to wound healing.
