Abstract
Objective
To verify microbiological culture positivity of hospitalized patients, with a nursing prescription for bed bath, in three disjoint and sequential periods of bed bath modalities: conventional (CBB), disposable (DBB) and disposable plus 2% chlorhexidine degerming (DBB-CX).
Methods
This is an ecological, time series study of 48 months, in three periods (P1=CBB; P2=DBB; P3=DBB-CX), with secondary data from electronic medical records of patients who were admitted to a hospital in the state of São Paulo, Brazil.
Results
In the periods of disposable baths, the percentage of culture positivity was, on average, 14.6% lower when compared to the months in which bed bath was conventional. In the DBB-CX period, the percentage of culture positivity was, on average, 19.3% lower when compared to the CBB period months. However, there is no evidence of difference in the percentage of culture positivity between DBB (b = -14.6%; 95%CI = (-18.9% to -10.3%) and DBB-CX (b = - 19.3%;95%CI = (-24.4% to -14.22%) For each year more in patients’ mean age, the percentage of culture positivity increases by an average of 0.3% (p=0.060). There was no seasonal association for microbiological culture positivity in bath modalities.
Conclusion
Microbiological culture positivity in patients with a nursing prescription for bed bath is lower when disposable modalities are used. It is recommended to routinely adopt DBB, leaving the prescription of DBB-CX only for skin degermation for invasive and operative procedures and hand hygiene of health professionals.
