The "bundle" approach to reduce the surgical site infection rate

RATIONALE, AIMS, AND OBJECTIVES

In Italy, since 2008, the surveillance of surgical site infections (SSIs) has been conducted following ECDC recommendations, according to the protocol of the National System of Surveillance of Surgical Site Infections. In 2009, in Piedmont region, where the study was conducted, it was introduced a survey of a "bundle" for every patient under SSIs surveillance. The bundle includes 5 items: infection risk index calculation, preoperative shower, trichotomy, antibiotic prophylaxis, and body temperature control. The aim of this study is the evaluation of the incidence rate of the SSIs in relation to the implementation of the bundle from January 1st to December 31st, 2012.

METHOD

This study is an observational study (retrospective cohort). The regional surveillance system collected 3314 surgical operations during the year 2012 from 37 hospitals. The represented surgical categories were hip prosthetic surgery (HPRO: 1992 cases) and colon surgery (COLO: 1322 cases). The bundle was implemented in 1114 and 671 operations, respectively. Univariate and multivariate analysis were conducted stratifying the sample for hip surgery and colorectal surgery, with the purpose to identify an association between the implementation of the bundle and a decrease of the rate of SSIs.

RESULTS

From the analysis, the bundle resulted as a protective factor for the infection risk in colon surgery (odds ratio [OR], 0.55; 95% confidence interval [CI], 0.38-0.78). The main risk factors were American Society of Anesthesiologists score ≥ 3 (OR, 1.57; 95% CI, 1.10-2.24) and contamination class ≥ 3 (OR, 2.02; 95% CI, 1.37-2.97). In the hip surgery, the application of the bundle was not statistically associated to a decrease of the risk of infection.

CONCLUSION

The use of surgical bundle seems to reduce significantly the SSIs rate in the colon surgery.

Delivery of written and verbal information on healthcare-associated infections to patients: opinions and attitudes of a sample of healthcare workers

Background

Patients education is considered a valuable mean to prevent and control healthcare-associated infections (HAIs). This cross-sectional study aims to assess declared practices of healthcare workers (HCWs) regarding the delivery of information about HAIs to patients.

Methods

A 14-item multiple-choice questionnaire was designed to assess the attitudes and declared practices of HCWs (physicians, nurses and nursing assistants). Between October 2012 and October 2013, we surveyed a sample of HCWs from 4 acute hospitals in Piedmont (North-western Italy). Written information was available at three hospitals (A, B and C) and verbal information at the last one (hospital D).

Results

We surveyed 288 HCWs (79 physicians, 124 nurses and 85 healthcare assistants). At hospital A, B and C, 128 (71.6%) HCWs declared that written information was usually delivered to any patient and 145 (66.5%) that nurses usually delivered it. Only 42 (26.3%) of them – 97.6% nurses –declared that they usually delivered written information to patients. Among all surveyed HCWs, 210 (72.9%) declared that patients also receive verbal information on HAI – mainly by nurses (70.8%) and physicians (50%) – but only 88 (29,2%) – 23.8% physician and 48.8% nurses – declared that they usually informed patients. Finally, 83 (27.7%) HCWs believed that they should decide whether or not to deliver information to patient case by case.

Conclusions

A formal policy requiring to deliver written information is most likely not enough to induce HCWs to better inform patients about HAIs. Health Trusts might introduce more target actions to reinforce HCWs’ practices, such as training and internal auditing.

[Knowledge, attitudes, and training needs of residents in Preventive Medicine and Hygiene in Italy, in the context of Primary Health Care]

In June 2015, the working group "Primary Health Care" of the Italian Society of Hygiene Representatives of Hygiene and Preventive Medicine Residents, performed an online questionnaire survey among residents of this specialty in Italy, to analyze their training needs regarding primary health care. In total, 730 residents in 32 schools were invited to participate by email, of whom 40.7% (297/730) completed the questionnaire. Most of the respondents were female (66.7%) and 40.1% were enrolled in a school in northern Italy. Almost half of participating residents were enrolled in the second or third year of the five-year program. Over 65% reported interest in deepening their knowledge in each of the proposed thematic areas of primary healthcare. For each area, less than one quarter of respondents (range 5-22%) considered satisfactory the skillsets acquired in that area. Eighty-seven percent reported that the option to do electives in primary health care during the residency was available to them.
