Evaluating the efficacy of the infection control liaison nurse in the hospital.

The infection control liaison nurse (ICLN) is a nurse in the ward, appointed to participate in education for infection control, and to liaise between the ward and the infection control nurse (ICN). The efficacy of ICLNs was evaluated when a guideline on urinary catheter care was introduced in a 1000-bed hospital in Hong Kong. The 27 public wards were divided randomly into a test (24 wards) and control group (three wards), and ICLNs were appointed in the test group by the nursing administration. For education, the ICN conducted in-service lectures for both groups, while in the test group, the ICLNs also conducted tutorials for all ward nurses. Before and after the education programme, prevalence surveys were conducted to detect incorrect practices on urinary catheter care. Three practices were evaluated: the securing of catheters, presence of kinking and the use of urinary bags with a drainage spigot. Before education, the percentage of incorrect practices in the test groups was 63%, which was comparable to the 68% of the control group (P = 0.40, chi 2 = 0.71). After education, the percentage of incorrect practices in the test group (36%) was significantly lower than the 48% in the control group (P less than 0.05, chi 2 = 4.25). This indicates that ICLNs can indeed enhance the education programme for infection control.

The employment of ward opinion leaders for continuing education in the hospital.

Opinion leaders (OLs) are members within a social group with significant social influence over others. A guideline on urinary catheter care was introduced in three groups (A, B and C) of two randomly allocated wards. Two OLs per ward were identified by nurses in groups A and B, using a sociometric method. For education, inservice lectures for 30% of nurses and OLs tutorials for all nurses were used in group A; OLs tutorials in B, lectures in C and ward nurses were in turn responsible for educating new arrivals of student nurses. Before and after the education programme, the guideline's frequency of practice was assessed by surveying 30% of randomly selected nurses and by direct observation for incorrect practices. A student's quiz on the guideline was also conducted. For all three methods of measurement, the best results were in group A followed by B and C; and the differences for the three groups were significant (p less than 0.05). This indicates that continuing education in the hospital can be effectively conducted by the enlistment of ward OLs.

Hospital use of chlorine disinfectants in a hepatitis B endemic area--a prevalence survey in twenty hospitals.

A survey was conducted to assess the uses of chlorine disinfectants in twenty hospitals in Hong Kong. In the 149 areas visited, the charge nurses were interviewed on the use of chlorine disinfectants. A high proportion of uses (44%) were not at the recommended dilution and only 88 (57%) of the 154 samples were within +/- 10% of the manufacturers quoted chlorine content. Samples with inadequate chlorine were found among all six types of chlorine disinfectants, although sodium dichloroisocyanurate tablets conformed to the quoted strength on 88% occasions. Higher usage frequency and better dilution practices were noted for hospitals with a disinfectant policy.

Educational needs in patient care practices in Hong Kong.

We conducted a survey on staff perceptions of what the educational needs would be for an infection surveillance and control program in patient care practices in 10 hospitals in Hong Kong. Seven hundred twenty nurses were interviewed and were requested to select their needs from six topics: isolation procedures, disinfection of environment and instruments, surgical wound care, urinary catheter care, prevention of hospital-acquired pneumonia, and prevention of infusion therapy sepsis. According to their pattern of needs, the clinical units could be divided into three groups. Staff members in the "medically oriented units," consisting of the medical, geriatric, obstetric, and intensive care units, indicated that their greatest needs were in the areas of isolation procedures and disinfection of environment and instruments, whereas nurses in the "surgically oriented units," consisting of surgical, orthopedic, and gynecologic units, indicated that surgical wound care was the area where education was most needed. The pattern in the third group, the pediatric units, was similar to that of medical units in indicating isolation procedures and disinfection of environment and instruments as the greatest needs but differed in having a higher score for prevention of hospital-acquired pneumonias and a lower score for surgical wound care. An effective educational program should take these needs into consideration. We discuss the application of the survey findings in planning in-service education in infection control.
