The experience of infection prevention and control nurse (IPCN) in conducting post-discharge surveillance (PDS) of surgical site infections (SSI): A qualitative study.

BACKGROUND: Surgical Site infections (SSI) are healthcare-associated infections (HAI) resulting from surgical procedures, which can increase morbidity, mortality, and economic burden. SSI surveillance is useful for detecting the magnitude of SSI cases and evaluating the impact of SSI prevention implementation. Post-discharge surveillance (PDS) of SSIs may identify more significant cases. To the best of our knowledge, there is no research exploring the experiences of Infection Prevention and Control Nurse (IPCN) in conducting PDS of SSI. METHODS: To explore the experience of IPCN in conducting PDS of SSI. A qualitative transcendent phenomenological (descriptive) research, using a purposive sampling technique with 15 informants from 9 hospitals in Indonesia. Data were collected through in-depth direct and semi-structured interviews and analyzed using thematic analysis through Nvivo 12 plus software. RESULTS: Five themes were generated, including the stages of PDS of SSI, the collaborative role of PDS of SSI officers, inhibiting factors of PDS of SSI, supporting factors of PDS of SSI, and optimization of PDS of SSI. CONCLUSION: This study provides a deep understanding of the implementation PDS of SSI through an exploration of IPCN experiences, offering insights into the execution and various challenges faced by hospitals in conducting PDS of SSI.

Post-Discharge Clostridioides difficile Infection after Arthroplasties in Poland, Infection Prevention and Control as the Key Element of Prevention of C. difficile Infections.

Clostridioides difficile is still one of the most common causes of hospital-acquired infectious diarrhea (CDI), and the incidence of CDI is one of the indicators that allows conclusions to be derived on the correctness of antibiotic administration. The objective of this observational study was the analysis of post-discharge CDI incidence in patients undergoing hip or knee arthroplasty, in order to specify optimum conditions for the surgical procedures and outpatient postoperative care. One-year observational study. Public Polish hospitals. Retrospective records for 83,525 surgery patients having undergone hip or knee arthroplasty were extracted from the Polish National Health Fund databases. CDI and/or antibiotic prescriptions in the 30 day post-surgery period were expressed per 1000 surgeries with antibiotic prescription on discharge or in ambulatory care, respectively. The CDI incidence rate was 34.4 per 10,000 patients, and 7.7 cases per 100,000 post-surgery patient-days. Patients who were prescribed at least one antibiotic were diagnosed with CDI more often than patients who had no antibiotic treatment (55.0/1000 patients vs. 1.8/1000 patients). In the multifactorial analysis, the following factors were significant: being at least 65 years of age, trauma as the cause of surgery, length of stay over 7 days, HAIs other than CDI and taking beta-lactams and/or quinolones but not macrolides in the post-discharge period. Postoperative antibiotic prescription in patients undergoing joint replacement surgery is the main risk factor for CDI. These observations indicate the necessity of improvement of infection control programs as the key factor for CDI prevention.

Emerging Insight in the Use of an Active Post Discharge Surveillance Program in Spine Surgery: A Retrospective Pilot Study.

BACKGROUND: With smartphones being present in everyday life, we have witnessed an increasing use of applications designed for mobile communication devices that are aimed at facilitating patient engagement in different medical arenas. Such applications are meant to improve communications with patients and ultimately improve patient care. The aim of this study was to report on our early experiences using Active Post Discharge Surveillance (APDS) relative to invasiveness of the spine surgery and patient age and gender. METHODS: A retrospective chart review was performed including all patients who volunteered to use application-based APDS between September 1, 2017, and September 30, 2018. The primary outcome was the number of APDS uses. Secondary outcomes were inquiries that led to a change of treatment or induced a readmission and patient satisfaction. Regression analysis was performed regarding the influence of invasiveness, age, and gender on the incidence of APDS use. RESULTS: The average number of individual APDS communications was 3.6 with no difference between degrees of severity of invasive surgery, age, or gender. APDS inquiries induced unexpected readmissions in 4 patients (66.6% of all readmissions) and postoperative treatment regimen changes in 4 other patients. Thirty-three patients (86.8%) reported being satisfied with APDS usage. CONCLUSIONS: This is the first study to investigate use of interactive APDS in patients undergoing elective spine surgery. Our data suggest that patient age, gender, or invasiveness of surgery is not associated with the usage of APDS.

Post-discharge surveillance and positive virus detection in two medical staff recovered from coronavirus disease 2019 (COVID-19), China, January to February 2020.

Since December 2019, 62 medical staff of Zhongnan Hospital in Wuhan, China have been hospitalised with coronavirus disease 2019. During the post-discharge surveillance after clinical recovery, swabs were positive in two asymptomatic cases (3.23%). Case 1 had presented typical clinical and radiological manifestations on admission, while manifestation in Case 2 was very mild. In conclusion, a small proportion of recovered patients may test positive after discharge, and post-discharge surveillance and isolation need to be strengthened.

Service improvement study to improve care for patients who developed a surgical site infection after discharge.

BACKGROUND: many patients develop surgical site infection (SSI) after they have been discharged from hospital. SSI rate is a quality measure intended to support healthcare providers with useful information to improve service and patient outcomes. AIM: the purpose of the study was to gain some local insight into current practice and to inform and improve clinical practice for patients who develop SSIs after they have been discharged. METHOD: a quantitative approach was taken, using retrospective data collection and analysis of patient records, of patients reviewed by the tissue viability service after discharge over a 1-year period. FINDINGS: a total of 112 patients were included in the study. Of these, 59 were assessed as having developed an SSI, of whom 39 patients presented after discharge. Most of these patients had shorter inpatient stays and many were under the care of community nurses, but referral to the specialist tissue viability service to seek expert advice was often delayed. CONCLUSION: the study has highlighted the potential value of post-discharge surveillance in contributing to more accurate SSI rates, and the importance of patients and community nurses being provided with clear, understandable information to ensure patients receive timely and effective management, which could reduce the severity of, and duration of treatment for, SSIs.

Surgical site infection in elective clean and clean-contaminated surgeries in developing countries.

BACKGROUND: Surgical site infection (SSI) is both the most frequently studied healthcare-associated infection and the most common healthcare-associated infection in the developing world. A systematic review and meta-analysis was conducted to evaluate the relative size of this burden and to estimate the prevalence of SSI in clean and clean-contaminated surgeries in a large sample of countries in the developing world. METHODS: A systematic search of the MEDLINE/PubMed, Scopus, and LILACS databases was conducted to identify studies providing the prevalence of SSI in elective clean and clean-contaminated surgeries in 39 countries or regions around the world. Data of interest were limited to publications from January 2000 to December 2017. Studies with information on the number of cases of SSI and number of total elective clean and clean-contaminated surgeries during the same period were included in this evaluation. Studies lacking clear definition of the total number of exposed patients were excluded. RESULTS: Based on the combined data from the 99 articles evaluated in this analysis, the overall prevalence of SSI in elective clean and clean-contaminated surgeries was estimated to be 6% (95% confidence interval (CI) 5-7%). This increased to 15% (95% CI 6-27%) when considering only those reports with post-discharge surveillance data. The overall prevalence of SSI in Africa/Middle East, Latin America, Asia, and China was 10% (95% CI 6-15%), 7% (95% CI 5-10%), 4% (95% CI 4-5%), and 4% (95% CI 2-6%), respectively. Significant variability in the data was confirmed by both the funnel plot and the Egger test (p=0.008). CONCLUSIONS: Although the data are variable, it is clear that the incidence of SSI in the developing world is higher than that in the developed world.

Benchmarking for surgical site infections among gastrointestinal surgeries and related risk factors: multicenter study in Kuwait.

PURPOSE: To measure surgical site infection (SSI) rates among gastrointestinal surgeries and to identify the associated risk factors. PATIENTS AND METHODS: We conducted a multicenter, retrospective, surveillance-based study of adults undergoing gastric, colon, and small bowel (SB) procedures from January to December 2016. Univariate and multivariate analyses were conducted to determine the predictive variables in each surgery. RESULTS: In total, 71 of 2,099 patients developed SSI - 0.8%, 19.8%, and 10.8% following gastric, colon, and SB surgeries, respectively. In gastric surgery, the risk factors identified by univariate analysis were age, duration, wound class, risk index, emergency, and scope use (P<0.05). Logistic regression analysis revealed that the laparoscopic approach was the only significant predictor, with an inverse relationship of SSI rate vs open gastric surgery (P<0.05). Prolonged duration was a significant risk factor for developing SSI in colon surgery, and emergency was a significant risk for development of SSI in SB surgery. Gram-negative bacilli were the main causative pathogens, with a high percentage of multidrug-resistant organisms. CONCLUSION: Variances in SSI rates and risk factors among gastric, colon, and SB surgery were detected. The use of an endoscope in gastric surgeries exhibited a protective effect against the development of SSI. The reduction of the SSI rate can be achieved by targeted preventive interventions for the identified risk factors.

Surgical site infection surveillance following total knee arthroplasty: Tertiary care hospital experience.

INTRODUCTION: Surgical Site Infection (SSI) after knee arthroplasty is a major cause of morbidity and mortality that increases the hospital stay, financial burden and mental anguish of the patient. Infection Control Unit at Aga Khan University Hospital (AKUH) incorporated total knee arthroplasty in its surgical care surveillance program and started collecting data in June 2012. The purpose of this study is to review Surgical Site Infection (SSI) rates in patients undergoing primary total knee replacement (TKR) surgery. PATIENTS AND METHODOLOGY: All patients from June 2012 to December 2013 undergoing knee arthroplasty at our hospital were included. Data was acquired from the hospital SSI database for knee arthroplasty surgery. Data was collected by SSI nurses for inpatients a well as post-discharge monitoring in clinics till 90 days post-op follow-up. The work has been reported in line with the PROCESS criteria. RESULTS: During this time period a total of 164 patients had primary TKR at AKUH. Out of these, 85 patients (52%) had bilateral TKR while 79 (48%) had unilateral TKR. The overall SSI was in 2 patients (1.2%). CONCLUSION: Identifying SSIs is multidimensional. Since our 2 infected cases after TKR occurred after discharge, this highlights the importance of post-discharge surveillance and not limiting the surveillance for inpatients only. Furthermore, the SSI program may be effective in controlling postoperative wound infections.

Identifying the Infection Control Areas Requiring Modifications in Thoracic Surgery Units: Results of a Two-Year Surveillance of Surgical Site Infections in Hospitals in Southern Poland.

BACKGROUND: Surgical site infection (SSI) is considered to be a priority in infection control. The objective of this study is the analysis of results of active targeted surveillance conducted over a two-year period in the Department of Thoracic Surgery at the Pulmonology and Thoracic Surgery Center in Bystra, in southern Poland. PATIENTS AND METHODS: The retrospective analysis was carried out on the basis of results of active monitoring of SSI in the 45-bed Department of Thoracic Surgery at the Pulmonology and Thoracic Surgery Center in Bystra between April 1, 2014 and April 30, 2016. Surgical site infections were identified based on the definitions of the European Centre for Disease Prevention and Control (ECDC) taking into account the time of symptom onset, specifically, whether the symptoms occurred within 30 d after the surgical procedure. Detection of SSI relied on daily inspection of incisions by a trained nurse, analysis of medical and nursing entries in the computer system, and analysis of all results of microbiologic tests taken in the unit and in the operating room. RESULTS: In the study period, data were collected regarding 1,387 treatment procedures meeting the registration criteria. Forty cases of SSI were detected yielding an incidence rate of 3%. Most cases (55%) were found in the course of hospitalization and 45% were detected after the patient's discharge. The SSIs were classified as follows: superficial, 37.5%; deep infections, 7.5%; and organ/space infection, 55%. Among patients who were diagnosed with SSI, most were male (77.5%). For patients with an American Society of Anesthesiologists (ASA) score I-II the incidence rate was 2%; ASA score III or more, 3.7%. The incidence rate varied from 0.3% in clean surgical site to 6.5% in clean-contaminated site. CONCLUSIONS: The study validated the usefulness of targeted surveillance in monitoring SSIs in patients hospitalized in thoracic surgery departments. Surgical site infection surveillance identified areas of care requiring modifications, namely, organization of post-discharge and microbiologic diagnostics of infection cases.

Reliability and validity of using telephone calls for post-discharge surveillance of surgical site infection following caesarean section at a tertiary hospital in Tanzania.

BACKGROUND: Surgical site infection (SSI) is a common post-operative complication causing significant morbidity and mortality. Many SSI occur after discharge from hospital. Post-discharge SSI surveillance in low and middle income countries needs to be improved. METHODOLOGY: We conducted an observational cohort study in Dodoma, Tanzania to examine the sensitivity and specificity of telephone calls to detect SSI after discharge from hospital in comparison to a gold standard of clinician review. Women undergoing caesarean section were enrolled and followed up for 30 days. Women providing a telephone number were interviewed using a structured questionnaire at approximately days 5, 12 and 28 post-surgery. Women were then invited for out-patient review by a clinician blinded to the findings of telephone interview. RESULTS: A total of 374 women were enrolled and an overall SSI rate of 12% (n = 45) was observed. Three hundred and sixteen (84%) women provided a telephone number, of which 202 had at least one telephone interview followed by a clinical review within 48 h, generating a total of 484 paired observations. From the clinical reviews, 25 SSI were diagnosed, of which telephone interview had correctly identified 18 infections; telephone calls did not incorrectly identify SSI in any patients. The overall sensitivity and specificity of telephone interviews as compared to clinician evaluation was 72 and 100%, respectively. CONCLUSION: The use of telephone interview as a diagnostic tool for post-discharge surveillance of SSI had moderate sensitivity and high specificity in Tanzania. Telephone-based detection may be a useful method for SSI surveillance in low-income settings with high penetration of mobile telephones.

Surgical site infection after caesarean section: space for post-discharge surveillance improvements and reliable comparisons.

Surgical site infections (SSI) after caesarean section (CS) represent a substantial health system concern. Surveying SSI has been associated with a reduction in SSI incidence. We report the findings of three (2008, 2011 and 2013) regional active SSI surveillances after CS in community hospital of the Latium region determining the incidence of SSI. Each CS was surveyed for SSI occurrence by trained staff up to 30 post-operative days, and association of SSI with relevant characteristics was assessed using binomial logistic regression. A total of 3,685 CS were included in the study. A complete 30 day post-operation follow-up was achieved in over 94% of procedures. Overall 145 SSI were observed (3.9% cumulative incidence) of which 131 (90.3%) were superficial and 14 (9.7%) complex (deep or organ/space) SSI; overall 129 SSI (of which 89.9% superficial) were diagnosed post-discharge. Only higher NNIS score was significantly associated with SSI occurrence in the regression analysis. Our work provides the first regional data on CS-associated SSI incidence, highlighting the need for a post-discharge surveillance which should assure 30 days post-operation to not miss data on complex SSI, as well as being less labour intensive.

The alertness, gait and mortality of severely ill patients at two months after admission to a resource poor sub-Saharan hospital--Why is post-discharge surveillance not routine everywhere?

BACKGROUND: Mortality, the first level of the first tier of the Outcomes Measures Hierarchy used to assess the value of health care, is the only hospital outcome usually measured. Gait and alertness after discharge are important to patients; they capture much of the second level of the first tier of the hierarchy, and are required to more fully assess the benefits, value and quality of care. AIM: To assess the alertness, gait and mortality of severely ill patients at two months after admission to a resource poor sub-Saharan hospital. METHODS: 193 severely ill patients admitted to a Ugandan hospital were followed up for up to 60 days. RESULTS: 34% of patients died, 52% were alert and calm with a stable independent gait, 2% had an unstable gait, 6% were bedridden and 7% were lost to follow-up within 60 days of admission: 7.4% of patients discharged alert with a stable gait died within 30 days and 13.9% within 60 days; 26.9% of patients discharged without a stable gait died within 60 days. Sixty day mortality was 5% if patients had a stable independent gait on admission, 25% if they had an unstable gait or needed help to walk, and 50% if they were bedridden. Simple logistic regression models based on cheap easily available data predicted 30 day mortality, alertness and gait (c statistic of both models 0.89 SE 0.03). CONCLUSION: In a resource poor setting gait and alertness assessments are of prognostic value, and practical and informative methods of patient follow-up.

Health insurance database for post-discharge surveillance of surgical site infection following arthroplasty.

BACKGROUND: Surgical site infection surveillance (SSI) is important for the improvement of care and patient safety. Most SSI surveillance systems focus on hospital settings, whereas numerous infectious events occur after discharge. AIM: To evaluate the patient care trajectory after discharge, we linked the hospital discharge database and the National Health Insurance Cross-Schemes Information System (NHI-CIS) to trace hip or knee arthroplasty infection (HKAI). METHODS: A retrospective analysis was performed using the permanent 1/97th sample of the whole NHI-CIS database. A total of 1739 patients underwent hip or knee arthroplasty between January 1st, 2011 and December 31st, 2011. Patients rehospitalized for HKAI were detected using a specific published algorithm. Non-rehospitalized HKAI patients were identified using a novel tracking algorithm based on ambulatory care consumption: nurse intervention, antibiotics and bandage purchase. FINDINGS: Of the 1739 studied patients, 20 patients (1.1%) were rehospitalized for HKAI. Fourteen (70%) of the HKAI events occurred within the first two months after surgery, two occurring during the patients' surgical hospital stay. Using ambulatory care data, 10 additional cases were suspected of developing HKAI in the year following their surgery. HKAI incidence rate was then estimated to be 1.76% (95% confidence interval: 1.14-2.38%). CONCLUSION: Although the study sample was limited, we demonstrated that each HKAI occurring after discharge could not be traced by the in-hospital information system alone. This result emphasizes the need for having a passive routine tool for post-discharge surveillance such as the NHI-CIS database.

Postdischarge surveillance for infection following cesarean section: A prospective cohort study comparing methodologies.

OBJECTIVE: To assess how enhanced postdischarge telephone follow-up calls would improve case finding for surgical site infection (SSI) surveillance after cesarean section. METHODS: We conducted a prospective cohort study of all patients who delivered by cesarean section between April 22 and August 22, 2010. In addition to our routine surveillance, using clinical databases and electronic patient records, we also made follow-up calls to the patients at 7, 14, and 30 days postoperation. A standard questionnaire with questions about symptoms of SSI, health-seeking behaviors, and treatment received was administered. Descriptive statistics and univariate analysis were performed to assess the effect of the enhanced surveillance. RESULTS: One hundred ninety-three patients underwent cesarean section during this study period. Standard surveillance identified 14 infections with telephone follow-ups identifying an additional 5 infections. Using the call as a gold standard, the sensitivity of the standard methodology to capture SSI was 73.3%. The duration of the calls ranged from 1 to 5 minutes and were well received by the patients. CONCLUSIONS: Results suggest that follow-up telephone calls to patients following cesarean section identifies 26.3% of the total SSIs. Enhanced surveillance can provide more informed data to enhance performance and avoid underestimation of rates.

The mortality of acutely ill medical patients for up to 60days after admission to a resource poor hospital in sub-Saharan Africa compared with patients of similar illness severity admitted to a Danish Regional Teaching Hospital--an exploratory observational study.

BACKGROUND: The outcomes of patients with the same severity of illness in the developed and developing countries have not been compared. Illness severity can now be measured anywhere by the National Early Warning Score (NEWS). METHODS: An exploratory observational study that compared the 7, 30 and 60 days mortality of 195 Ugandan and 588 Danish acutely ill medical patients that had a NEWS >6 at the time of their admission to the hospital. The association of vital sign changes, alertness and mobility at admission on subsequent outcome was explored. RESULTS: More Kitovu (34.4%) than Danish patients (22.1%) died within 60 days of admission (OR 1.85, 95% CI 1.27-2.71, p 0.001). However, the survival of non-comatose patients admitted without severely deranged vital signs or who were able to stand without help was identical in both cohorts (Chi square 0.32, p 0.57): these patients made up 50% of all Ugandan and 60% of all Danish patients. In contrast the survival curves of patients admitted in a coma were widely divergent within a week of hospital admission and remained so for a further 60 days (Chi square 10.29, p 0.001). CONCLUSION: This small hypothesis generating observational study with huge selection and treatment bias found no survival difference at 60 days after admission to resource rich and resource poor hospitals for patients without severely deranged vital signs or who were able to stand without help.
