Cancellation of elective surgical procedures in the university teaching hospital center Yalgado Ouedraogo in Burkina Faso: incidence, reasons and proposals for improvement

Background: Cancellation of scheduled surgery leads to operating theatre under-occupancy and is recognised as a major cause of emotional trauma to patients and their families. This study aimed to assess the incidence of elective surgery cancellation in order to make proposals for healthcare improvement.Methods: A prospective study was undertaken on cancellation of scheduled surgery in the general surgery service. Cancellation is considered to have occurred when planned surgery did not take place on the day it was scheduled and recognised as ‘final’ when it was no longer considered at a later date. Cancellations were classed as ‘avoidable’ or ‘unavoidable’.Results: A total of 103 surgeries were scheduled for patients with an average age of 41.1 years. Abdominal surgery (36.9%) dominated and 63.1% (n = 65) of the operations were scheduled. Some 36.9% (n = 38) of interventions were delayed, of which 9.7% (n = 10) were definitively cancelled and 27.2% (n = 28) were carried forward. Half of the cancellations (47.4%) were related to equipment and 31.6% related to patient factors. Hospital-related cancellation accounted for 63.9%. Cancellation was avoidable in 68.5% of cases. A financial cause was relevant for 16.6% (n = 6) and 2.6% of cancellations were due to a ‘long preceding intervention’.Conclusion: The impact of cancellation is high and better organisation and communication between relevant role players within the operating theatre should reduce unnecessary cancellation.Keywords: cancellation, elective surgery, operating theatr

Low birth weight in newborns: epidemiological aspects and neonatal prognosis within Bogodogo teaching hospital, Burkina Faso

Background: Low birthweight is one of the main causes of neonatal death, after asphyxia and infections. This study purpose is to determine the epidemiological aspects and prognosis of this condition. Methods: This was a descriptive and analytical cross-sectional study. Data were collected prospectively from July 1st to September 30th, 2021 within Bogodogo Teaching Hospital. The study population included the overall newborns and their mothers. Results: The low birthweight frequency was estimated at 17.26% of live births. The average age was 26.06±5.8 years. Housewives accounted for 68.6% of cases against 78.9% for mothers in union. Unschooled mothers accounted for 38.3%. Mothers having medium socio-economic status accounted for 83.1% of cases. The average number of gesture was 2.60±1.62 and average parity was 2.72±1.76. Premature newborns accounted for 51.1% of cases. Females represented 55.6% of cases, giving a sex ratio of 0.80. The average weight was 1970.64±375.21 g with extremes of 900g and 2450g. The neonatal mortality rate was estimated at 9.4%. Occupation (p=0.003), marital status (p=0.001), place of residence (p=0.011), socioeconomic level (p=0.000), body mass index (p=0.001) and multiple pregnancy (p= 0.01) were statically associated with low birthweight at term. Conclusions: At the end of this study, it appears that further action is still needed to reduce low birthweight frequency, which implies improving the socio-economic conditions of the population.

Modélisation et simulation d’un champ photovoltaïque utilisant un convertisseur élévateur de tension (boost) avec le logiciel MATLAB /SIMULINK

International audienceCe travail présente une contribution pour une meilleure conception d’un convertisseur boost permettant à l’aide d’une commande de recherche du point de puissance maximale MPPT (Maximum Power Point Tracking) de retrouver la puissance maximale du champ photovoltaïque (PV) à tout moment.En effet à partir des modèles de convertisseur boost existant dans la littérature nous avons développé une variante de convertisseur et calculé ses différents paramètres. Les simulations réalisées avec Matlab/Simulink ont permis d’optimiser la production du champ PV et d’élucider le fait que le champ PV peut fonctionner à son point maximal de puissance s’il est interfacé par un convertisseur qui recherche à tout instant la puissance maximale
