A microbiology study of the surgical site infection, at a hospital in northern Portugal

Surgical site infections (SSIs) remain a major clinical problem in terms of morbidity, mortality, time spent in hospital and overall direct and indirect costs. Objectives: To measure the prevalence of the SSI, by type of surgery and microbiologically characterization, in adult patients undergoing surgery during 2015 at a public hospital in northern Portugal. Methods: A prospective study, attended by 609 adult patients, undergoing surgery. The sociodemographic and clinical data of the population, as well as the surgical procedure and microbiological study were analyzed using Microsoft Access 2013. Results: In the sample of 609 adults undergoing surgery, it was found that 62.89% of surgical wound were cleaned, 15.8% were clean-contaminated, 8.70% were contaminated and 9.36% infected. About 62.52% of the intervened patients had antibiotic prophylaxis prior to surgery. Out of all surgeries, 33.3% were laparoscopic. The percentage of SSI was 5.74%; In these positive cases, only 3.61% was identiied the responsible bacteria. The urgent surgeries have more infections when compared to the programmed ones. In colon surgery the number of infections was 60% after cholecystectomy (22.86%). In hernioplasty, infection occurred in only 2.86% of the patients. The most isolated bacteria was Escherichia coli with 59%, in which 30% are -producing-lactamases of extended spectrum, followed by Pseudomonas aeruginosa (13.6%) and Serratia marcescens (13.6%). The mortality rate was 14.8%. Pseudomonas aeruginosa was isolated in 3 of 4 patients who died. Conclusions: The most microorganisms belong to the group of Gram-negative and are usually linked to infections associated with health care.

Surgical site infection in colorectal surgery

Surgical Site Infection is one of the most common infection associated with health care, but can also be the most preventable situation. Surgical site infection in patients undergoing colorectal surgery varies according to the literature, from 3.5 to 21.3%, being identiied as the highest rate of infection among elective procedures and emergency. Objectives: To identify and characterize the occurrence of surgical site infection in patients undergoing colorectal surgery at a hospital in northern Portugal. Methods: A prospective study in a hospital in the north of Portugal in 2015, patients admitted to the surgical service who underwent colorectal surgery. Patients were selected more than 24 hours of admission, obtaining a sample of 102 participants. The characterization of the patient and the surgery was done using a search in the irst 24 hours after surgery and the registration of the infection at the time of occurrence and 30 days after the intervention. Results: 102 participants, 67 (65.7%) were male with a mean age of 71.92 years (37-93 years) and 40.2% underwent emergency surgery. There was a prevalence of surgical site infection in 21 patients (20.6%). Among these 15 were male (71.4%) with mean age of 72.24 years. They were hospitalized on average 22 days, with an average of 19 days of hospitalization after surgery. Escherichia-coli was the microorganism most frequently isolated in culture studies with 13 (60.0%) cases of surgical site infection and organ/space was the main site identiied with infection - 38.1%. Conclusions: The prevalence of surgical site infection was 5.1% and Escherichia coli most common etiologic agent. It is suggested that other studies can analyze the associated factors with this type of infection.

Prevalence of surgical wound infection after surgery for breast cancer: systematic review

One of the known risk factors for abuse and neglect of the elderly is the decrease in functionat capacity, contributíng to self care dependency of instrumental actívities of daily living and basic activities of daily Itving (OMS, 2015). Methods: Cross-sectional study with non probabilistíc sample of 333 elderly, performed in a hospital, homes and day centers for the elderly. The data collectíon protocol tncluded socio-demographic data, Questíons to elicit Elder Abuse (Carney, Kahan B Paris, 2003 adap. By Ferreira Alves & Sousa, 2005), scale of instrumental actívi - ties of daily living Lawton and Brody and Katz index to assess the levei of independence in actívities of daily living. Objectives: To evaluate the assodation between abuse and neglect in the elderly, instrumental actívitíes of daily living and levei of independence in actívitíes of daily living. Results: Emotional abuse is signifícantty correlated with the levei of independence in activities of daity Uving (p = 0. 000), older peopie with less independence tend to have higher leveis of emotional abuse. The total abuse is signtficantly correlated with the leveis of independence in activittes of daily living (p = 0. 002), less independent elderty tend to suffer greater abuse and neglect. There were no statistically significant associations between abuse and neglect and instrumental activities of daily l1v1ng. Conclusions: The less independent elderly are more vulnerable to situatíons of abuse and neglect, being more exposed to emotional abuse. These results point to the need for health professionals/ nurses develop prevention interventions, including strategies to support carers and early screentng tn less independent elderly.

Antãoa "Polythecnic Institute o f Bragança, Bragança, Portugal; bEPI Unit, Public Health Institute, University of Porto, Portugal. Contact details: catarinaisabeln.amaraliSsmaU.com Introduction: Breast câncer is one of the most common mahgnant pathology in European countries, as Portugal, where annual inddence is around 90 new cases per 100,000 women. Breast surgery is the usual treatment for this pathology, however such procedure can be complicated by the infection of surgical site. Objectives: To know the prevalence and determtnants of surgtcal wound infection after breast surgery. Methods: We conducted a systematic review by searching of the Web of Sdence electronic database for articles published over the last s1x years 1n developed countries. Over three hundred dtatíons were obtained and after excludtng citations with reasons, fíve artícles met our inclusion criteria and were included in the present review. Results: Prevalence of surgical wound infection varied across studies between 0. 1% and 12. 5%. Bilateral mastectomy is assodated with higher prevalence of wound infectíon than unilateral mastectomy (3. 6% vs 3, 3%), lumpectomy with immediate breast reconstruction (IBR) is related with higher frequency of wound infectíon than surgery with no IBR (0, 5% vs 0, 1%), also, mastectomy with IBR is associated with higher prevalence of wound infectíon than mastectomy wtth no IBR (1, 5% vs 0, 3%) and breast surgery followed by axiltary lymph nade dissectíon is related with higher prevalence of wound infection than surgical procedures wtth no axillary lymph node dissection (2, 82% vs 1, 66%). Conclusions: Nurses that provide post-operatíve care to women after breast surgery should be aware about risk of wound tnfectíon, partícularly after more invasive procedures.
