Surgical Site Infections and Antimicrobial Resistance After Cesarean Section Delivery in Rural Rwanda.

Background: As the volume of surgical cases in low- and middle-income countries (LMICs) increases, surgical-site infections (SSIs) are becoming more prevalent with anecdotal evidence of antimicrobial resistance (AMR), despite a paucity of data on resistance patterns. Objectives: As a primary objective, this prospective study aimed to describe the epidemiology of SSIs and the associated AMR among women who delivered by cesarean at a rural Rwandan hospital. As secondary objectives, this study also assessed patient demographics, pre- and post-operative antibiotic use, and SSI treatment. Methods: Women who underwent cesarean deliveries at Kirehe District Hospital between September 23rd, 2019, and March 16th, 2020, were enrolled prospectively. On postoperative day (POD) 11 (+/- 3 days), their wounds were examined. When an SSI was diagnosed, a wound swab was collected and sent to the Rwandan National Reference Laboratory for culturing and antibiotic susceptibility testing. Findings: Nine hundred thirty women were enrolled, of whom 795 (85.5%) returned for the POD 11 clinic visit. 45 (5.7%) of the 795 were diagnosed with SSI and swabs were collected from 44 of these 45 women. From these 44 swabs, 57 potential pathogens were isolated. The most prevalent bacteria were coagulase-negative staphylococci (n = 12/57, 20.3% of all isolates), and Acinetobacter baumannii complex (n = 9/57, 15.2%). 68.4% (n = 39) of isolates were gram negative; 86.7% if excluding coagulase-negative staphylococci. No gram-negative pathogens isolated were susceptible to ampicillin, and the vast majority demonstrated intermediate susceptibility or resistance to ceftriaxone (92.1%) and cefepime (84.6%). Conclusions: Bacterial isolates from SSI swab cultures in rural Rwanda predominantly consisted of gram-negative pathogens and were largely resistant to commonly used antibiotics. This raises concerns about the effectiveness of antibiotics currently used for surgical prophylaxis and treatment and may guide the appropriate selection of treatment of SSIs in rural Rwanda and comparable settings.

Validation of a community-based survey assessing nonobstetric surgical conditions in Burera District, Rwanda.

BACKGROUND: Validated, community-based surveillance methods to monitor epidemiologic progress in surgery have not yet been employed for surgical capacity building. The goal of this study was to create and assess the validity of a community-based questionnaire collecting data on untreated surgically correctable disease throughout Burera District, Rwanda, to accurately plan for surgical services at a district hospital. METHODS: A structured interview to assess for 10 index surgically treatable conditions was created and underwent local focus group and pilot testing. Using a 2-stage cluster sampling design, Rwandan data collectors conducted the structured interview in 30 villages throughout the Burera District. Rwandan physicians revisited the surveyed households to perform physical examinations on all household members, used as the gold standard to validate the structured interview. RESULTS: A total of 2,990 individuals were surveyed and 2,094 (70%) were available for physical examination. The calculated sensitivity and specificity of the survey tool were 44.5% (95% CI, 38.9-50.2%) and 97.7% (95% CI, 96.9-98.3%), respectively. The conditions with the highest sensitivity and specificity were hydrocephalus, clubfoot, and injuries/infections. Injuries/infections and hernias/hydroceles were the conditions most frequently found on examination that were not reported during the interview. CONCLUSION: This study provides the first attempt to validate a community-based surgical surveillance tool. The finding of low sensitivity was likely related to limited access to care and poor health literacy. Accurate community-based surveys are critical to planning integrated health systems that include surgical care as a core component.

Validation of a community-based survey assessing non-obstetric surgical conditions in Burera District, Rwanda.

BACKGROUND: Community-based surveillance methods to monitor epidemiological progress in surgery have not yet been employed for surgical capacity building. The aim of this study was to create and assess the validity of a questionnaire that collected data for untreated surgically correctable diseases throughout Burera District, northern Rwanda, to accurately plan for surgical services. METHODS: A structured interview to assess for the presence or absence of ten index surgically treatable conditions (breast mass, cleft lip/palate, club foot, hernia or hydrocele [adult and paediatric]), hydrocephalus, hypospadias, injuries or wounds, neck mass, undescended testes, and vaginal fistula) was created. The interview was built based on previously validated questionnaires, forward and back translated into the local language and underwent focus group augmentation and pilot testing. In March and May, 2012, data collectors conducted the structured interviews with a household representative in 30 villages throughout Burera District, selected using a two-stage cluster sampling design. Rwandan physicians revisited the surveyed households to perform physical examinations on all household members, used as the gold standard to validate the structured interview. Ethical approval was obtained from Boston Children's Hospital (Boston, MA, USA) and the Rwandan National Ethics Committee (Kigali, Rwanda). Informed consent was obtained from all households. FINDINGS: 2990 individuals were surveyed, a 97% response rate. 2094 (70%) individuals were available for physical examination. The calculated overall sensitivity of the structured interview tool was 44·5% (95% CI 38·9-50·2) and the specificity was 97·7% (96·9-98·3%; appendix). The positive predictive value was 70% (95% CI 60·5-73·5), whereas the negative predictive value was 91·3% (90·0-92·5). The conditions with the highest sensitivity and specificity, respectively, were hydrocephalus (100% and 100%), clubfoot (100% and 99·8%), injuries or wounds (54·7% and 98·9%), and hypospadias (50% and 100%). Injuries or wounds and hernias or hydroceles were the conditions most frequently identified on examination that were not reported during the interview (appendix). INTERPRETATION: To the best of our knowledge, this study provides the first attempt to validate a community-based surgical surveillance tool. The finding of low sensitivity limits the use of the tool, which will require further revision, and calls into question previously published unvalidated community surgical survey data. To improve validation of community-based surveys, community education efforts on common surgically treatable conditions are needed in conjunction with increased access to surgical care. Accurate community-based surveys are crucial to integrated health system planning that includes surgical care as a core component. FUNDING: The Harvard Sheldon Traveling Fellowship.

Using electronic technology to improve clinical care - results from a before-after cluster trial to evaluate assessment and classification of sick children according to Integrated Management of Childhood Illness (IMCI) protocol in Tanzania.

BACKGROUND: Poor adherence to the Integrated Management of Childhood Illness (IMCI) protocol reduces the potential impact on under-five morbidity and mortality. Electronic technology could improve adherence; however there are few studies demonstrating the benefits of such technology in a resource-poor settings. This study estimates the impact of electronic technology on adherence to the IMCI protocols as compared to the current paper-based protocols in Tanzania. METHODS: In four districts in Tanzania, 18 clinics were randomly selected for inclusion. At each site, observers documented critical parts of the clinical assessment of children aged 2 months to 5 years. The first set of observations occurred during examination of children using paper-based IMCI (pIMCI) and the next set of observations occurred during examination using the electronic IMCI (eIMCI). Children were re-examined by an IMCI expert and the diagnoses were compared. A total of 1221 children (671 paper, 550 electronic) were observed. RESULTS: For all ten critical IMCI items included in both systems, adherence to the protocol was greater for eIMCI than for pIMCI. The proportion assessed under pIMCI ranged from 61% to 98% compared to 92% to 100% under eIMCI (p < 0.05 for each of the ten assessment items). CONCLUSIONS: Use of electronic systems improved the completeness of assessment of children with acute illness in Tanzania. With the before-after nature of the design, potential for temporal confounding is the primary limitation. However, the data collection for both phases occurred over a short period (one month) and so temporal confounding was expected to be minimal. The results suggest that the use of electronic IMCI protocols can improve the completeness and consistency of clinical assessments and future studies will examine the long-term health and health systems impact of eIMCI.
