Abstract - Text


Effective infection prevention (IP) succeeds with health care professionals" adherence to infection prevention guidelines, which currently showed to be not sufficient. The BMG-funded intervention study HygArzt (ZMVI1-2516FSB111) aims at postoperative, nosocomial infection reduction in trauma surgery and orthopedics through implementing infection prevention measures (IPM). Effective implementation requires promotion of desired behavior by considering psychological predictors of adherence, this present study aimed to identify.


Based on Ajzen's theory of planned behavior, a Likert-scaled questionnaire was developed, piloted, and distributed to physicians and nurses in three trauma surgical and orthopedic wards (N = 83). Results were generated using factor- (VARIMAX rotation), reliability- (Cronbach's alpha), correlation- (Pearson), and descriptive analyses.


The response rate was 52% (N=43). Relevant questionnaire items were bundled to content categories (scales) with scale reliability coefficients ranging between α = .67 and α = .89. Preliminary physician-specific results reflect the initial situation: 70% show positive attitude to IP, 78% very good to good knowledge about IPM, 53% value the priority of IP, 56% score commitment of supervisors as high, 56% rate satisfaction with implementation of IPM as moderate. 94% intend to adhere to IPM, which succeeds, at 34% always, at 42% almost always. In 72%, work environment is experienced as implementation-favorable. Adherence-relevant correlations were identified between: Adherence and internal control (r=.67, p<.002), negative emotions regarding IPM (r=-47, p<.04), behavioral intention (r=.56, p<.002), knowledge about IPM (r=.63, P<.004), and priority of IP (r=.49, p<.05), between satisfaction with implementation of IPM and priority of IP (r=.75, p<.000), supervisors" commitment (r=.74, p<.000), supervisors" commitment and priority of IP (r=.65, p<.003).


Most physicians reported positive attitude, good knowledge, high implementation intention, and implementation-favorable work environment. Potential for optimization exists with satisfaction with implementation of IPM, the priority of IP, supervisors" commitment, and adherence. The promotion of these, also of adherence-relevant personal characteristics, control expectancy, emotions, behavioral intention, knowledge, should be targeted in intervention phase for effective implementation of IPM.
