Prevalence and Management of Rhinosinusitis in Developing Countries: the Case of Mbingo Baptist Hospital, North West Region, Cameroon
Abstract:
Rhinosinusitis occurs worldwide and affects about 16% of the adult American population annually significantly impairing their quality of life. Allergic rhinitis and chronic rhinosinusitis are prevalent non communicable diseases increasing around the world, even in Africa.
This study is aimed at assessing the prevalence and management of rhinosinusitis in Mbingo Baptist Hospital, in children, teenagers and adults. In Cameroon, the investigator did not find any readily documented and published statistics indicating the case of rhinosinusitis. In the hospital where this study was carried out, observation made in the frequency of rhinosinusitis and knowing the possible complications prompted the investigator find out about the prevalence and its management.
Thus the following research question of “what is the prevalence and management of rhinosinusitis?”
Our main objective is to assess the prevalence and management of rhinosinusitis in Mbingo Baptist Hospital.
More specifically, the investigator will be able:
· To define and describe rhinosinusitis
· To assess the management of rhinosinusitis in MBH
· To come out with the prevalence of rhinosinusitis in MBH
· To ascertain the standard management of rhinosinusitis
The prevalence of AR is very high (>35%) among Nigerian Africans, and it is likely that environmental factors are responsible for major differences with other countries. Knowing the prevalence of Rhinosinusitis will serve as reference for many other investigations. This prevalence would tend to increase if the condition is not well managed at the level of the hospital.
This is a cross sectional study in which data are collected from the hospital registers for patients having rhinosinusitis since 2011 till 2015. With these data, we aim at giving the prevalence of rhinosinusitis during this period.
The study will also include 5 case studies met in the ENT department during the period of the study both on an in patient and outpatient basis.
We shall assess the demographic data, patient’s history and management. The aim of these case studies is to have an indepth idea on the management of rhinosinusitis in Mbingo Baptist Hospital compared to the already addressed international standards.
Statistics of all cases of rhinosinusitis were taken from the ENT department registers from the year 2011 to 2015 (January to September). It is obvious that the prevalence of adult patients with rhinosinusitis is more than two times the prevalence of both the children and teenagers mixed. The total number of children from 2011 to 2015 was 677, teenagers were 514 and adults 3477, for a final total of 4668 people with rhinosinusitis.
This may be due to the fact that adult patients have reinfections or relapsed conditions and therefore need to visit the hospital more frequently. This also may show their increase fragility and incapacity to control or to resist the allergens or causative agents. This information is better symbolized on figures 16, 17 and 18. For all of them the number of patients seen with rhinosinusitis was higher in 2014.
From the table indicating the total prevalence of Rhinosinusitis from 2011 to 2015, it is showing that the prevalence of rhinosinusitis is lowest in 2015 with a percentage of 10.5% and highest in 2011 (13.9%). The total average prevalence (from 2011 to 2015) is 11.7%. Since the department began being functional by 2011, population awareness about this condition was not well spread and resulted to an increase in prevalence in relation to the total number of patients seen in that year, which obviously is the smallest number.
As far as the management of rhinosinusitis is concerned, from the 5 case studies seen, it consisted in general of the following:Normal saline drops, Nasal decongestant, Corticosteroid spray and tablets, Antibiotics, Antihistamines, Functional Endoscopic Sinus Surgery.
To conclude, Rhinosinusitis which is the inflammation of the nasal mucosa, has proved to be a problem in the sub-Saharan African regions as described in the literature review.
It is a universal health concern in the sense that it affect anybody and anyway provided the allergens or causative agents are present.
This condition can either be acute or chronic, allergic and non-allergic, and can be managed medically and surgical, all depending on the gravity of the condition.
Though the prevalence of rhinosinusitis depends on the realities of each country and even reach up to 35% in Nigeria, the one identified by this study and representative of the whole country is lower (11.7%). The fact that this prevalence is around this average value, and considering the type of management done by the health professional which meet standard protocols and practice, we can say that rhinosinusitis is under control. Because population is dynamic, it may difficult to bring that value lower. Proper preventive measures will help reduce the prevalence of rhinosinusitis, among which the intensified education of the population and on preventive measures.
The standard guideline of management of rhinosinusitis will consist of one or the combination of the following:
1. Antihistamine (1 week to 1 month) (may continue for a period of 6 months)
2. Corticosteroids (2 weeks to 1 month)
3. Antibiotics (penicillins or cephalosporins with sometimes with an addition of anaerobes antibiotics like metronidazole) (5 days to 2 weeks dependently)
4. Nasal decongestant (1 to 2 weeks) (if associated with severe nasal congestion)
5. Nasal spray steroids (2 weeks to 1 month) (may continue for a period 6 months)
6. Surgical intervention (Functional Endoscopic Sinus Surgery) for those patients with facial sinuses polyps.
