Predictors of Surgical Site Infections among Patients Undergoing Open Urological Surgery at a Tertiary Hospital, Tanzania: A Cross Sectional Study

Prevalence, risk factors, and antimicrobial resistance of endemic healthcare-associated infections in Africa: a systematic review and meta-analysis

BACKGROUND

Healthcare-associated infections (HCAI) place a significant burden on healthcare systems globally. This systematic review and meta-analysis aimed to investigate the prevalence, risk factors, and aetiologic agents of endemic HCAI in Africa.

METHODS

MEDLINE/PubMed, CINAHL, and Global Health databases (EBSCOhost interface) were searched for studies published in English and French describing HCAI in Africa from 2010 to 2022. We extracted data on prevalence of HCAI, risk factors, aetiologic agents, and associated antimicrobial resistance patterns. We used random-effects models to estimate parameter values with 95% confidence intervals for risk factors associated with HCAI. This study was registered in PROSPERO (CRD42022374559) and followed PRISMA 2020 guidelines.

RESULTS

Of 2541 records screened, 92 were included, comprising data from 81,968 patients. Prevalence of HCAI varied between 1.6 and 90.2% with a median of 15% across studies. Heterogeneity (I2) varied from 93 to 99%. Contaminated wound (OR: 1.75, 95% CI: 1.31-2.19), long hospital stay (OR: 1.39, 95% CI: 0.92-1.80), urinary catheter (OR: 1.57, 95% CI: 0.35-2.78), intubation and ventilation (OR: 1.53, 95% CI: 0.85-2.22), vascular catheters (OR: 1.49, 95% CI: 0.52-2.45) were among risk factors associated with HCAI. Bacteria reported from included studies comprised 6463 isolates, with E. coli (18.3%, n = 1182), S. aureus (17.3%, n = 1118), Klebsiella spp. (17.2%, n = 1115), Pseudomonas spp. (10.3%, n = 671), and Acinetobacter spp. (6.8%, n = 438) being most common. Resistance to multiple antibiotics was common; 70.3% (IQR: 50-100) of Enterobacterales were 3rd -generation cephalosporin resistant, 70.5% (IQR: 58.8-80.3) of S. aureus were methicillin resistant and 55% (IQR: 27.3-81.3) Pseudomonas spp. were resistant to all agents tested.

CONCLUSIONS

HCAI is a greater problem in Africa than other regions, however, there remains a paucity of data to guide local action. There is a clear need to develop and validate sustainable HCAI definitions in Africa to support the implementation of routine HCAI surveillance and inform implementation of context appropriate infection prevention and control strategies.

Mentoring approaches in a safe surgery program in Tanzania: Lessons learned during COVID-19 and recommendations for the future

Background

COVID-19 has dramatically affected the delivery of health care and technical assistance. This is true in Tanzania, where maternal mortality and surgical infection rates are significantly higher than in high-income countries. This paper describes lessons learned about the optimal application of in-person and virtual mentorship in the Safe Surgery 2020 program to improve the quality of surgical services in Tanzania before and after the COVID-19 pandemic.

Methods

From January 2018 through December 2020, Safe Surgery 2020 supported 40 health facilities in Tanzania's Lake Zone to improve the quality of surgical care. A blended surgical mentorship model, employing both onsite and virtual mentorship, was central to the program's capacity development approach. With COVID-19, the program pivoted to full virtual mentorship. Through continuous learning and adaptation processes, including a human-centered design workshop, surveys assessing mentors' confidence with different competencies, and focus group discussions with mentors, mentees and safe surgery program staff, the program distilled the optimal use of mentorship models.

Results

Developing complex surgical skills, addressing contextual considerations, problem-solving, and building trusting relationships were best suited to in-person mentorship, whereas virtual mentorship was most effective in supporting mentees' quality improvement projects, data use, case discussions, and reinforcing clinical practices. Leading successful virtual learning required enhanced facilitation skills and active engagement of health facility leadership.

Conclusions

In-person and virtual mentorship offer distinct benefits and complement each other when combined. Investing more in-person mentorship at the beginning of programs allows for the establishment of trust that is foundational to effective mentorship.
