The Bundle approach to reduce SSI rate of colon surgery, Piedmont (Italy): experience of 2012-2017

Background

According to ECDC, Surgical Site Infections (SSI) are the second most frequent type of Healthcare Associated Infections (HAI) in Europe and in USA, and 9.5% of colon surgical procedures develop SSI. SSIs are associated with prolonged hospital stay, higher costs burden and higher attributable morbidity and mortality. Interventional programs can reduce the risk of SSI. Care bundles are a complex of EBM-based interventions on a specific population and setting, in order to improve clinical outcomes. A bundle is successful only if all its items are properly applied, through the ‘all-or-none’ method. Application of a bundle does not exclude other good clinical practices.

Methods

Data from 37 hospitals participating in the Regional SSI surveillance of Piedmont (Italy) were collected from 2012 to 2017. In hospitals applying the bundle, 4 bundle items had to be used in all the procedures: Temperature control, preoperative shower, trichotomy, antimicrobial prophylaxis. 6909 patients undergoing colon surgery were followed for 30 post-operative days to detect SSI events (According to ECDC 2016 Protocol). For some procedures, compliance to Bundle item application was ≤ 75%.

Results

6909 procedures were assessed: 3631 with no bundle application and 3278 with bundle application; in particular 974 were compliant to all bundle items (100%), while 2304 were compliant to 3 items or less (≤ 75%). We report a SSI risk of 11.20% for surgical procedures performed without bundle application; this risk decreases to 5.63% (OR: 0.49, 95% CI: 0,36-0,67; p < 0.001) when compliance to bundle is 100%. When compliance to bundle is ≤ 75% instead of 100%, SSI risk raises to 8.47% (OR: 1.49, 95% CI: 1.07-2.04; p = 0.002).

Conclusions

Care bundle, if properly applied, is associated to statistically significant reduction of SSI rate (51%) for colon surgical procedures. Bundle programs should be encouraged and improved in hospitals to reduce healthcare costs and burden of HAIs.

Key messages

The use of the 4-item Surgical Care Bundle is associated to statistically significant reduction (51%) of SSI rate for colon surgical procedures. Surgical Care Bundle programs should be recommended and improved in every hospital to reduce healthcare costs and burden of HAIs.

Compulsory vaccination policies: a systematic review about knowledge, attitudes and believes

Background

Vaccine hesitancy is a considerable issue in European Countries and leads to low coverage rates. Consequently, the implementation of national immunization programmes including the introduction of compulsory vaccination are required. It is interesting to determine citizens’ knowledge, attitudes and believes about vaccination policies, in order to more effectively define vaccination programs.

Methods

The present study systematically reviewed published studies evaluating attitudes towards mandatory vaccination programs. PubMed and Scopus scientific databases were searched and 4,198 results were returned, of these 29 met the inclusion criteria. PRISMA statements were followed.

Results

Twenty-two studies assessed attitudes towards mandatory vaccination programs in general, while 9 papers focused specifically on the Human Papilloma Virus (HPV) vaccine. Most of the studies were performed in Europe and North America. According to the assessed studies, the majority of the population seems to be in favour of compulsory vaccinations, from 53% to 97% for different vaccination programs. More resistance has been recorded for the HPV vaccination: the percentage of agreement for mandatory HPV vaccinations ranged from 27% to 63.5%. Furthermore, some studies investigated healthcare workers’ attitudes towards childhood and adult vaccinations. They pointed out that the general population is generally more in favour of mandatory vaccination policies than healthcare workers. The studies highlighted that the support to mandatory policies increased after their implementations.

Conclusions

The results presented in this review could be an important starting point to further understand the issue of vaccine hesitancy and support the implementation of effective vaccination strategies in Europe.

Key messages

Mandatory vaccination policies are generally well accepted among general population. More resistance is recorded for specific vaccination (HPV) or among specific population (healthcare workers).

The conventional protocol vs. a protocol including illumination with a fabric-based biophotonic device (the Phosistos protocol) in photodynamic therapy for actinic keratosis: a randomized, controlled, noninferiority clinical study

BACKGROUND

Topical photodynamic therapy (PDT) using methyl aminolaevulinate is a noninvasive treatment option suitable to treat clinical and subclinical actinic keratosis (AK) over a large area (field cancerization). The most widely used, conventional protocol in Europe includes illumination with a red-light lamp. This illumination commonly causes pain, and patients often cannot complete the treatment.

OBJECTIVES

The aims of this paper are twofold. The first aim is to introduce a novel protocol, the Phosistos protocol (P-PDT), which includes illumination with a fabric-based biophotonic device. The second and major aim is to assess the noninferiority, in terms of efficacy for PDT of AK, of P-PDT compared with the conventional protocol (C-PDT).

METHODS

A randomized, controlled, multicentre, intraindividual clinical study was conducted. Forty-six patients with grade I-II AK of the forehead and scalp were treated with P-PDT on one area (280 AK lesions) and with C-PDT on the contralateral area (280 AK lesions). The primary end point was the lesion complete response (CR) rate at 3 months, with an absolute noninferiority margin of -10%. Secondary end points included pain scores, incidence of adverse effects and cosmetic outcome.

RESULTS

Three months following treatment, the lesion CR rate of P-PDT was noninferior to that of C-PDT (79·3% vs. 80·7%, respectively; absolute difference -1·6%; one-sided 95% confidence interval -4·5% to infinity). The noninferiority of P-PDT to C-PDT in terms of the lesion CR rate remained at the 6-month follow-up (94·2% vs. 94·9%, respectively; absolute difference -0·6%; one-sided 95% confidence interval -2·7% to infinity). Moreover, the pain score at the end of illumination was significantly lower for P-PDT than for C-PDT (mean ± SD 0·3 ± 0·6 vs. 7·4 ± 2·3; P < 0·001).

CONCLUSIONS

P-PDT is noninferior to C-PDT in terms of efficacy for treating AK of the forehead and scalp and resulted in much lower pain scores and fewer adverse effects. What's already known about this topic? Topical photodynamic therapy using methyl aminolaevulinate is effective for treating actinic keratosis. In Europe, the conventional protocol involves illumination with a red-light lamp. Unfortunately, pain is often experienced by patients undergoing this protocol. An alternative protocol that uses daylight illumination has recently been shown to be as effective as the conventional protocol while being nearly painless. However, this alternative protocol can be conducted only in suitable weather conditions. What does this study add? The Phosistos protocol is demonstrated to be as effective as the conventional protocol, nearly as painless as the daylight protocols and suitable year round for treatment of actinic keratosis.

Knowledge, attitudes and beliefs towards compulsory vaccination: a systematic review

Currently, many countries are dealing with groups refusing available recommended vaccinations. Despite several studies having demonstrated the efficacy of mandatory vaccinations in ensuring herd immunity, opposition is widespread. The aim of our study was to systematically review published studies evaluating attitudes towards mandatory vaccination programs. PubMed and Scopus scientific databases were searched and 4,198 results were returned, of these 29 met the inclusion criteria. Twenty-two studies assessed attitudes towards mandatory vaccination programs in general, while 9 papers focused specifically on the Human Papilloma Virus (HPV) vaccine. Most of the studies were performed in Europe and North America. According to the assessed studies, the majority of the population seems to be in favour of compulsory vaccinations, although attitudes differed among studies. The results presented in this review could be an important starting point to further understand the issue of vaccine hesitancy and support the implementation of effective vaccination strategies.
