Improving pain management for trauma patients at two Rwandan emergency departments.

Background: Little is known regarding the effectiveness of pain protocols and guideline use in Emergency Departments (ED) in Sub-Saharan Africa. Therefore, to shed light on this research gap, this study had the following objectives: 1) to evaluate if the implementation of the Essential Pain Management (EPM) course combined with mentorship to use the World Health Organization (WHO) pain ladder-based protocol improves the quality of pain management among trauma patients at the ED of two teaching hospitals in Rwanda; and 2) to determine barriers to implementing the WHO pain ladder-based protocol among trauma patients in the same settings. Methods: This was a pre- and post-intervention study. The intervention was 1-day essential pain management training for ED clinical staff followed by 1 week mentorship on the use of the WHO pain ladder-based protocol. Results: We enrolled 261 patients (47.5% pre versus 52.5% post intervention), most of them were aged between 21 and 40 (60% pre versus 33% post intervention), and male (76% pre versus 73% post intervention). The quality of pain management at the ED improved as shown by the decrease of the number of patients with undocumented pain scores from 58% to 24% after the intervention (p-value > 0.001) and the increase of the number of patients with mild pain from 37% to 62% (p-value > 0.001). In addition, patients who were satisfied with the quality of pain management increased significantly from 42% before the intervention to 80% (p-value > 0.001). Barriers to the implementation of the WHO pain ladder-based protocol were identified related to staff (i.e. inadequate experience), to the hospital (i.e. poor documentation), and to patients (i.e. reluctance to report pain). Conclusion: The implementation of the EPM course along with mentorship to use the WHO pain ladder-based protocol significantly improved the quality of pain management for trauma patients in EDs of both referral hospitals. Despite this, some barriers remain unfixed such as inadequate staff experience, poor documentation, and patient's reluctance to report pain. Appropriate interventions should be implemented to address the identified barriers and ensure adequate pain management for patients admitted at EDs in public hospitals in Rwanda.

Investigating the Association Between a Risk-Directed Prophylaxis Protocol and Postoperative Nausea and Vomiting: Validation in a Low-Income Setting.

BACKGROUND: The efficacy of postoperative nausea and vomiting (PONV) prevention protocols in low-income countries is not well known. Different surgical procedures, available medications, and co-occurring diseases imply that existing protocols may need validation in these settings. We assessed the association of a risk-directed PONV prevention protocol on the incidence of PONV and short-term surgical outcomes in a teaching hospital in Rwanda. METHODS: We compared the incidence of PONV during the first 48 hours postoperatively before (April 1, 2019-June 30, 2019; preintervention) and immediately after (July 1, 2019-September 30, 2019; postintervention) implementing an Apfel score-based PONV prevention strategy in 116 adult patients undergoing elective open abdominal surgery at Kigali University Teaching Hospital in Rwanda. Secondary outcomes included time to first oral intake, hospital length of stay, and rate of wound dehiscence. Interrupted time series analyses were performed to assess the associated temporal slopes of the outcome before and immediately after implementation of the risk-directed PONV prevention protocol. RESULTS: Compared to just before the intervention, there was no change in the odds of PONV at the beginning of the postintervention period (odds ratio [OR], 0.23; 95% confidence interval [CI], 0.05-1.01). There was a decreasing trend in the odds of nausea (OR, 0.60; 95% CI, 0.36-0.97) per month. However, there was no difference in the incidence of nausea immediately after implementation of the protocol (OR, 0.96; 95% CI, 0.25-3.72) or in the slope between preintervention and postintervention periods (OR, 1.48; 95% CI, 0.60-3.65). In contrast, there was no change in the odds of vomiting during the preintervention period (OR, 1.01; 95% CI, 0.61-1.67) per month. The odds of vomiting decreased at the beginning of the postintervention period compared to just before (OR, 0.10; 95% CI, 0.02-0.47; P = .004). Finally, there was a significant decrease in the average time to first oral intake (estimated 14 hours less; 95% CI, -25 to -3) when the protocol was first implemented, after adjusting for confounders; however, there was no difference in the slope of the average time to first oral intake between the 2 periods ( P = .44). CONCLUSIONS: A risk-directed PONV prophylaxis protocol was associated with reduced vomiting and time to first oral intake after implementation. There was no substantial difference in the slopes of vomiting incidence and time to first oral intake before and after implementation.

Correlation of Malaria Rapid Test and Peripheral Blood Smear Microscopy among Patients attending Byumba Health Centre.

Background: Malaria presents a diagnostic challenge in most tropical countries including Rwanda. Microscopy remains the gold standard for diagnosing malaria, however, it is labour intensive and depends upon the skill of the examiner. Malaria rapid diagnostic tests (MRDTs) have been developed as an easy, convenient alternative to microscopy. Methods: A cross sectional study was conducted from October to November 2019 on 130 febrile patients who were directed to the laboratory department for blood screening for malaria parasites at Byumba Health centre. The main objective of this study was to correlate Microscopy and MRDTs in diagnosis of malaria. Results: After signing a consent form, blood samples were collected and screened for malaria parasites microscopically and by using MRDTs. Data collection forms were filled with relevant information and obtained results for MRDTs and for peripheral blood smear were recorded. The collected data were statistically analyzed using GraphPad Prism 9 software. The mean age found to be 16 years old. In this study peripheral blood smear microscopy was considered as a reference method. The sensitivity and specificity of RDT Histidine-Rich Protein 2 (HRP-2) were calculated and found to be 96.6% and 60% respectively. The negative predictive value was found to be 92.85% where positive predictive value was 73.3%. Conclusion: MRDTs should be used along with microscopy to avert complications associated with delayed diagnosis and similar studies are required to identify alternative techniques with high specificity for the diagnosis of malaria.

Influenza-like illness during pregnancy: results from a study in the eastern townships, Province of Quebec.

OBJECTIVES: (1) To assess the frequency of influenza and influenza-like illness (ILI) during pregnancy; (2) to explore the associated risk of adverse maternal and fetal outcomes. METHODS: All women who delivered at the Sherbrooke University Hospital in the province of Quebec during the period of February 15 to April 30, 2002, were invited to complete a questionnaire. Medical records of participating women and of their infants were reviewed. Complement-fixing antibody titres against influenza A were measured in paired sera drawn during antenatal screening and at delivery. RESULTS: The study participation rate was 96.3%. Nine of 517 women stated that they had received the influenza vaccine during pregnancy, and only 3 of 47 women with a chronic pulmonary disease had been immunized. Overall, 464 ILI episodes were reported by 331 women, and a significant maternal complication occurred in 8 cases. ILI episodes resulted in medical consultations in 55.4% of cases, and in antibiotic prescriptions in 13.8% of cases. There was no indication of an increased frequency of adverse perinatal outcomes associated with ILI during pregnancy. Paired sera were available for 156 participants and seroconversion was observed in 6.6%. CONCLUSIONS: ILI during pregnancy was associated with health services utilization but complications were infrequent. More studies are needed to demonstrate the usefulness of routine vaccination of healthy pregnant women against influenza.
