Knowledge, attitude, and adherence to malaria control guidelines and the prevalence of Plasmodium species infection in localities across transmission and ecological zones in Cameroon.

Background: Despite a scale up of control interventions over the years, malaria remains a major public health and economic concern in Cameroon, contributing considerably to hospitalization and deaths. The effectiveness of control strategies depends on the extent of adherence by the population to national guidelines. This study assessed the influence of human knowledge, attitudes, and practices related to malaria and its control on the prevalence of malaria parasite infection, with implications for the elimination of the disease. Methodology: This is a cross-sectional community and hospital-based study, covering the five ecological and three malaria transmission zones in Cameroon. A pre-tested semi-structured questionnaire was used to document socio-demographic and clinical parameters as well as knowledge, attitudes, and practices toward malaria control and management. Consenting participants were screened for malaria parasite with rapid diagnostic test (mRDT) of the peripheral blood. Association between qualitative variables was determined using the chi-square test and logistic regression analysis. Results: A total of 3,360 participants were enrolled, 45.0% (1,513) of whom were mRDT positive, with 14.0% (451/3,216) and 29.6% (951/3,216) having asymptomatic parasitaemia and malaria, respectively. Although most participants knew the cause, symptoms, and control strategies, with 53.6% (1,000/1,867) expertly knowledgeable about malaria overall, only 0.1% (2/1,763) individuals were fully adherent to malaria control measures. Conclusion: The risk of malaria in Cameroon remains high, with the population considerably knowledgeable about the disease but poorly adherent to national malaria control guidelines. Concerted and more effective strategies aimed at improving knowledge about malaria and adherences to control interventions are necessary to ultimately eliminate the disease.

Evaluating Shifts in Perception After a Pilot Trauma Quality Improvement Training Course in Cameroon.

INTRODUCTION: Trauma is a major contributor to the global burden of disease, with low- and middle-income countries (LMICs) being disproportionately affected. Trauma Quality Improvement (QI) initiatives could potentially save an estimated two million lives each year. Successful trauma QI initiatives rely on adequate training and a culture of quality among hospital staff. This study evaluated the effect of a pilot trauma QI training course on participants' perceptions on leadership, medical errors, and the QI process in Cameroon. METHODS: Study participants took part in a three-day, eight-module course training on trauma QI methods and applications. Perceptions on leadership, medical errors, and QI were assessed pre and post-course using a 15-item survey measured on a five-point Likert scale. Median pre- and post-course scores were compared using the Wilcoxon signed-rank test. Knowledge retention and course satisfaction were also evaluated in a post-course survey and evaluation. RESULTS: A majority of the 25 course participants completed pre-course (92%) and post-course (80%) surveys. Participants' perceptions of safety and comfort discussing medical errors at work significantly increased post-course (pre-median = 5, IQR [4-5]; post-median = 5, IQR [5-5]; P = 0.046). The belief that individuals responsible for medical error should be held accountable significantly decreased after the course (pre-median = 3, IQR [2-4]; post-median = 1, IQR [1-2]; P < 0.001). Overall satisfaction with the course was high with median scores ≥4. CONCLUSIONS: These initial results suggest that targeted trauma QI training effectively influences attitudes about QI. Further investigation of the effect of the trauma QI training on hospital staff in larger courses is warranted to assess reproducibility of these findings.

Baseline Patient Safety Culture in Cameroon: Setting a Foundation for Trauma Quality Improvement.

BACKGROUND: Trauma quality improvement (QI) has resulted in decreased trauma mortality and morbidity in high-income countries and has the potential to do the same in low- and middle-income countries. Effective implementation of QI programs relies on a foundational culture of patient safety; however, studies on trauma-related patient safety culture in Sub-Saharan Africa remain scarce. This study assesses baseline patient safety culture in Cameroon to best identify opportunities for improvement. MATERIALS AND METHODS: Over a 3-week period, the Hospital Survey on Patient Safety Culture was administered in three hospitals in the Littoral region of Cameroon. Percentages of positive responses (PPRs) were calculated across 42 items in 12 survey dimensions. A mixed-effects logistic regression model was used to summarize dimension-level percentages and confidence intervals. RESULTS: A total of 179 trauma-related hospital personnel were surveyed with an overall response rate of 76.8%. High PPRs indicate favorable patient safety culture. Of the 12 dimensions evaluated by the Hospital Survey on Patient Safety Culture, nine had a PPR below 50%. Dimensions particularly pertinent in the context of QI include Nonpunitive Response to Errors with a PPR of 25.8% and Organization Learning-Continuous Improvement with a PPR of 64.7%. CONCLUSIONS: The present study elucidates an opportunity for the development of trauma patient safety culture in Cameroon. Low PPR for Nonpunitive Response to Errors indicates a need to shift cultural paradigms from ascribing individual blame to addressing systemic shortcomings of patient care. Moving forward, data from this study will inform interventions to cultivate patient safety culture in partnering Cameroonian hospitals.

Rapid assessment method for prevalence and intensity of Loa loa infection.

OBJECTIVE: To assess the validity of observations on eye worm and Calabar swellings for the rapid assessment of the prevalence and intensity of loiasis at the community level. METHOD: A total of 12895 individuals over the age of 15 years living in 102 communities in Cameroon and Nigeria took part in the study. A standardized questionnaire was administered to participants from whom finger-prick blood samples were collected and examined for Loa loa microfilariae. Rapid assessments of the prevalence and intensity of loiasis were made on the basis of a history of eye worm or Calabar swellings. FINDINGS: There was a strong correlation between the indices of the rapid assessment procedures and the parasitological indices of L. loa endemicity. The rapid assessment indices were effective in diagnosing high-risk communities (sensitivity 94-100%; specificity 66-92%). The highest sensitivity (100%) and specificity (92%) were obtained with a rapid assessment procedure based on a history of eye worm lasting 1-7 days together with confirmation by the guided recognition of a photograph of adult L. loa in the eye. CONCLUSION: Rapid assessment of the prevalence and intensity of loiasis at the community level can be achieved using a procedure based on the history of eye worm lasting 1-7 days together with confirmation by the guided recognition of a photograph of an adult L. loa in the eye.
