Urinary Tract Infections and Associated Factors among Patients with Indwelling Urinary Catheters Attending Bugando Medical Centre a Tertiary Hospital in Northwestern Tanzania

Catheter-associated urinary tract infections in Africa: Systematic review and meta-analysis

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) account for the majority of device-associated healthcare-acquired infections with significant morbidity and mortality worldwide. In developing countries with limited resources, the burden of CAUTI have substantial burden owing to the lack of well-organized infection prevention and control. Although there are studies in African countries, the magnitude of CAUTI is inconsistent. Therefore this systematic review and meta-analysis aimed to determine the pooled prevalence of CAUTI in Africa and identify the pathogens involved.

METHODS

Systematic review of articles from different databases and search engines such as Medline/PubMed, Google Scholar, Science Direct, and African Journal online were systematically searched to identify potential studies. Data were extracted on Microsoft Excel spreadsheet and analyzed using STATA 17.0. The pooled prevalence of CAUTI was estimated using a random effects model, inverse of variance was used to assess statistical heterogeneity across studies. Egger's tests was performed to identify possible publication bias.

RESULTS

This systematic review and meta-analysis incorporated twenty studies, revealing a pooled prevalence of CAUTI at 43.28%. Gram-negative bacteria were the leading cause of CAUTI accounts for 82.9%. Escherichia coli (45.06%) was the most frequent gram-negative bacterial isolate involved in CAUTI followed by Klebsiella spp (24.17%). Staphylococcus aureus was the predominant gram-positive bacterial isolate, accounting for 53.24% of gram-positive associated cases in CAUTI.

CONCLUSION AND RECOMMENDATIONS

In conclusion, the high prevalence of CAUTI in Africa underlines a pressing healthcare challenge. Addressing this issue requires a concerted effort, encompassing health education, infection prevention measures, resource allocation, and collaborative initiatives to enhance patient safety and mitigate the impact of CAUTI on healthcare systems in the region. As prolonged catheterization increases the risk of infection, catheters should only be used for proper indications and removed promptly when no longer needed.

The Impact of Urinary Catheterization on the Antibiotic Susceptibility of ESBL-Producing Enterobacterales: A Challenging Duo

INTRODUCTION

Antimicrobial resistance (AMR) is currently a growing concern among healthcare providers, underscoring the importance of describing the regional susceptibility profile for common microorganisms that are associated with urinary tract infections (UTIs). This knowledge serves as the foundation for proper empirical therapeutic recommendations tailored to local susceptibility patterns.

RESULTS

We found a high prevalence of ESBL-producing strains (36.9%), with Escherichia coli and Klebsiella spp. being the most prevalent isolated bacteria. Among the catheterized patients, Klebsiella spp. emerged as the primary etiology, with a significant correlation between catheterization and Proteus spp. (p = 0.02) and Providencia stuartii (p < 0.0001). We observed significant correlations between urinary catheterization and older age (68.9 ± 13.7 years vs. 64.2 ± 18.1 years in non-catheterized patients, p = 0.026) and with the presence of an isolate with extensive drug resistance (p < 0.0001) or even pandrug resistance (p < 0.0001). Susceptibility rates significantly decreased for almost all the tested antibiotics during the study period. Notably, susceptibility was markedly lower among catheterized patients, with the most pronounced differences observed for carbapenems (59.6% versus 83.4%, p < 0.0001) and aminoglycosides (37.1% versus 46.9%, p = 0.0001).

MATERIALS AND METHODS

We conducted a retrospective study analyzing the susceptibility profiles of 724 extended-spectrum beta-lactamases (ESBL)-producing Enterobacterales isolated from urine cultures. Our focus was on highlighting susceptibility profiles among isolates associated with urinary catheterization and assessing the shifts in the susceptibility rates over time.

CONCLUSIONS

The constant rise in AMR rates among Enterobacterales presents significant challenges in treating severe infections, particularly among urinary catheterized patients. This trend leaves clinicians with limited or no effective treatment options. Consequently, the development and implementation of personalized treatment protocols are imperative to ensure efficient empirical therapies.

Patterns and outcomes of health-care associated infections in the medical wards at Bugando medical centre: a longitudinal cohort study

BACKGROUND

The burden of healthcare associated infections (HCAIs) in low- and middle-income countries (LMICs) remains underestimated due to diagnostic complexity and lack of quality surveillance systems. We designed this study to determine clinical diagnosis, laboratory-confirmed, associated factors and risks of HCAIs.

METHODS

This hospital-based longitudinal cohort study was conducted between March and June 2022 among adults (≥ 18 years) admitted in medical wards at BMC in Mwanza, Tanzania. Patients who were negative for HCAIs by clinical evaluations and laboratory investigations during admission were enrolled and followed-up until discharge or death. Clinical samples were collected from patients with clinical diagnosis of HCAIs for conventional culture and antimicrobial sensitivity testing.

RESULTS

A total of 350 adult patients with a median [IQR] age of 54 [38-68] years were enrolled in the study. Males accounted for 54.6% (n = 191). The prevalence of clinically diagnosed HCAIs was 8.6% (30/350) of which 26.7% (8/30) had laboratory-confirmed HCAIs by a positive culture. Central-line-associated bloodstream infection (43.3%; 13/30) and catheter-associated urinary tract infection (36.7%; 11/30) were the most common HCAIs. Older age was the only factor associated with development of HCAIs [mean (± SD); [95%CI]: 58.9(± 12.5); [54.2-63.5] vs. 51.5(± 19.1); [49.4-53.6] years; p = 0.0391) and HCAIs increased the length of hospital stay [mean (± SD); [95%CI]: 13.8 (± 3.4); [12.5-15.1] vs. 4.5 (± 1.7); [4.3-4.7] days; p < 0.0001].

CONCLUSION

We observed a low prevalence of HCAIs among adult patients admitted to medical wards in our setting. Central-line-associated bloodstream infections and catheter-associated urinary tract infections are common HCAIs. Significantly, older patients are at higher risk of acquiring HCAIs as well as patients with HCAIs had long duration of hospital stays.

Prospective cohort study of incidence and risk factors for catheter-associated urinary tract infections in 145 intensive care units of 9 Latin American countries: INICC findings

PURPOSE

Identify urinary catheter (UC)-associated urinary tract infections (CAUTI) incidence and risk factors (RF) in Latin American Countries.

METHODS

From 01/01/2014 to 02/10/2022, we conducted a prospective cohort study in 145 ICUs of 67 hospitals in 35 cities in nine Latin American countries: Argentina, Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Panama, and Peru. To estimate CAUTI incidence, we used the number of UC-days as the denominator, and the number of CAUTIs as numerator. To estimate CAUTI RFs, we analyzed the following 10 variables using multiple logistic regression: gender, age, length of stay (LOS) before CAUTI acquisition, UC-days before CAUTI acquisition, UC-device utilization (DU) ratio, UC-type, hospitalizationtype, ICU type, facility ownership, and time period.

RESULTS

31,631 patients, hospitalized for 214,669 patient-days, acquired 305 CAUTIs. The pooled CAUTI rate per 1000 UC-days was 2.58, for those using suprapubic catheters, it was 2.99, and for those with indwelling catheters, it was 2.21. The following variables were independently associated with CAUTI: age, rising risk 1% yearly (aOR = 1.01; 95% CI 1.01-1.02; p < 0.0001 female gender (aOR = 1.28; 95% CI 1.01-1.61; p = 0.04), LOS before CAUTI acquisition, rising risk 7% daily (aOR = 1.07; 95% CI 1.06-1.08; p < 0.0001, UC/DU ratio (aOR = 1.14; 95% CI 1.08-1.21; p < 0.0001, public facilities (aOR = 2.89; 95% CI 1.75-4.49; p < 0.0001. The periods 2014-2016 and 2017-2019 had significantly higher risks than the period 2020-2022. Suprapubic catheters showed similar risks as indwelling catheters.

CONCLUSION

The following CAUTI RFs are unlikely to change: age, gender, hospitalization type, and facility ownership. Based on these findings, it is suggested to focus on reducing LOS, UC/DU ratio, and implementing evidence-based CAUTI prevention recommendations.

Prospective Cohort Study of Incidence and Risk Factors for Catheter-associated Urinary Tract Infections in 212 Intensive Care Units of Nine Middle Eastern Countries

Objectives

To identify urinary catheter (UC)-associated urinary tract infections (CAUTI) incidence and risk factors (RF) in nine Middle Eastern countries.

Methods

We conducted a prospective cohort study between 1 January 2014 and 2 December 2022 in 212 intensive care units (ICUs) of 67 hospitals in 38 cities in nine Middle Eastern countries (Bahrain, Egypt, Jordan, Kuwait, Lebanon, Morocco, Saudi Arabia, Turkey, and the UAE). To estimate CAUTI incidence, we used the number of UC days as denominator and the number of CAUTIs as numerator. To estimate CAUTI RFs, we analyzed the following 10 variables using multiple logistic regression: patient sex, age, length of stay (LOS) before CAUTI acquisition, UC-days before CAUTI acquisition, UC-device utilization (DU) ratio, hospitalization type, ICU type, facility-ownership, country income level classified by World Bank, and time period.

Results

Among 50 637 patients hospitalized for 434 523 patient days, there were 580 cases of acquired CAUTIs. The pooled CAUTI rate per 1000 UC days was 1.84. The following variables were independently associated with CAUTI: age, rising risk 1.0% yearly (adjusted odds ratio [aOR] = 1.01, 95% CI: 1.01-1.02; p < 0.0001); female sex (aOR = 1.31, 95% CI: 1.09-1.56; p < 0.0001); LOS before CAUTI acquisition, rising risk 6.0% daily (aOR = 1.06, 95% CI: 1.05-1.06; p < 0.0001); and UC/DU ratio (aOR = 1.11, 95% CI: 1.06-1.14; p < 0.0001). Patients from lower-middle-income countries (aOR = 4.11, 95% CI: 2.49-6.76; p < 0.0001) had a similar CAUTI risk to the upper-middle countries (aOR = 3.75, 95% CI: 1.83-7.68; p < 0.0001). The type of ICU with the highest risk for CAUTI was neurologic ICU (aOR = 27.35, 95% CI: 23.03-33.12; p < 0.0001), followed by medical ICU (aOR = 6.18, 95% CI: 2.07-18.53; p < 0.0001) when compared to cardiothoracic ICU. The periods 2014-2016 (aOR = 7.36, 95% CI: 5.48-23.96; p < 0.001) and 2017-2019 (aOR = 1.15, 95% CI: 3.46-15.61; p < 0.001) had a similar risk to each other, but a higher risk compared to 2020-2022.

Conclusions

The following CAUTI RFs are unlikely to change: age, sex, ICU type, and country income level. Based on these findings, it is suggested to focus on reducing LOS, UC/DU ratio, and implementing evidence-based CAUTI prevention recommendations.

The Quality of Life of Patients Living with a Urinary Catheter and Its Associated Factors: A Cross-Sectional Study in Egypt

BACKGROUND

In Arabic countries, no research has focused on the experience of patients with indwelling urinary catheters. This cross-sectional study is the first to evaluate the catheter-specific quality of life (QoL) of patients living with a urinary catheter in Egypt.

METHODS

This study was conducted from April to September 2017, using a convenience sample of patients from a University Hospital. Data were collected using the International Consultation on Incontinence Questionnaire-Long-Term Catheter QoL (ICIQ-LTCQoL) instrument, along with a demographic datasheet.

RESULTS

141 were enrolled, with 47.5% inpatients, 52.5% outpatients. A total of 70.9% reported problems with catheter function, and 92.2% reported that the catheter affected their daily lives. Place (inpatient or outpatient) was significantly associated with the total score of the ICIQ-LTCQoL (mean difference (MD) 6.34 (95% CI: 3.0 to 9.73)) and both subscales (catheter function subscale: MD = 4.92 (95% CI: 2.12 to 7.73) and lifestyle impact subscale: MD = 1.44 (95% CI: 0.3 to 2.63)), suggesting that outpatients have poorer QoL than inpatients. Moreover, catheter material was significantly related to the catheter function domain with Silicone Foley Catheter (100% Silicon) users experiencing poorer QoL related to catheter function than those with Latex Foley Catheter (Silicon-coated) (MD 4.43 (95% CI: 0.62 to 8.24). Workers/employees were found to have poorer QoL than those who were retired (MD = 4.94 (95% CI: 0.3 to 9.63)).

CONCLUSION

The results highlight the necessity of assessing function and concern regarding urinary catheter use and its impact on QoL, as well as its determinants. Evidence-based educational programs should be designed to enhance patients' self-care abilities to relieve their sense of distress and enhance their confidence in caring for their catheters.

Life with an Indwelling Urinary Catheter: Experiences from Male Patients Attending the Urology Clinic at a Tertiary Hospital in Northwestern Tanzania-A Qualitative Study

Experiences from patients living with a long-term indwelling urinary catheter (IUC) at home among men attending urology clinics have not been reported. Evidence-based information on such experiences is important for improving nursing care in low- and middle-income countries such as Tanzania. Using a descriptive phenomenological qualitative research design, we observed two main themes: "Adjustments to positive living with a catheter at home", denoting that social interaction and psychological and spiritual support are important to positively live with the catheter, and "The home environment influences negative or positive living", considering intimacy and altered body image to significantly influence the ability to practice sex, leading to wives' self-sacrifice. Respondents experienced difficulties in living with a long-term IUC at home due to a lack of information from healthcare professionals on how to manage their catheters and urine bags. In adjusting to positive or negative living with a catheter at home, respondents had to figure out strategies to minimize psychological and emotional trauma and hasten the adjustment process. A clear guideline or checklist is needed to ensure that all important information is provided by health professionals at the time of discharge and during subsequent visits to patients on how to care for the catheter insertion sites and help them adjust to living with a long-term IUC.
