ABSTRACT

Introduction: The study of mortality is an indicator that allows a control and a review of the therapeutic measures in the hospital environment. The purpose of this work was to determine the epidemiological profile of the patients who died and analyse the circumstances of the death in a hospital service. Material and Methods: It is a retrospective descriptive study conducted in the service of Stomatology, maxillofacial and plastic surgery of the face over a period of 10 years (from January 1999 to December 2008). Seventy-two cases have been taken into account. Results: The crude death rate was 4.29%. Higher level of male has been noted with a sex ratio of 1.77. The most affected age groups were the 3rd and 2nd decades, respectively with 20.8% and 19.4% with an average age of 39 years. Cellulitis of the face and their complications were responsible for deaths in 58.33% of cases. The majority of deaths occurred between 6 p.m. and 6 a.m. (65.28%). These deaths were preventable in 5.6% of cases. Conclusion: Facing the lack of description of the ultimate circumstances of death in the medical records, the conclusion of this study has been the establishment of a regular medical audit in the service, which would track mortality in order to reduce its rate.

1. Introduction

The study of mortality in a community allows defining the lines of death prevention and readjusting health policy [1] . In a hospital service, such a study allows a control and a review of the therapeutic measures; these are likely to degradation in their implementation over the years, which requires a periodic criticism [2] [3] . If in developed countries this periodic review is systematic in different hospital services, in our tropics, it is practically not the case [4] [5] [6] . Although deaths are numerous, no study makes it possible to focus on the factors and main causes of mortality. This would suggest improvements in the management of personnel and equipment in order to provide care of quality [7] [8] .

The Service of Stomatology, maxillofacial and plastic surgery of the face alike the other services of this reference hospital have no unit of death audit. That’s why it appeared appropriate to initiate this work which has for objectives:

1) the determination of the epidemiological profile of the patients who died in our service;

2) and the analysis of the death circumstances.

2. Material and Method

It is a retrospective descriptive study which took place in the Department of Stomatology, maxillofacial and plastic surgery of the face from January 1999 to December 2008, which is 10 years.

Were included in this study all patients who died during their hospital stay with a medical record to date. However the patients who died before admission and those whose medical record was missing or incomplete were excluded. At the end of the vote count there were 114 deaths and only 72 fulfills our inclusion criteria have been selected for the study.

The information was collected from registers (admissions, hospitalization, and death) and the patient’s medical record.

The studied parameters were:

・ Mortality indicators [9] : the number of death (number of deaths per year), the crude death rate (number of deaths during a given period reported to the number), the specific rate of mortality (mortality rate calculated according to different variable, ex: age, sex, ...), and the proportional mortality (share that is a cause or a group of causes in general mortality).

・ Analysis of the death concerned; the time of occurrence, the length of stay in the service, the immediate cause of death (clinical picture at the time of death), the period of occurrence within one month and the concept of avoidability (fatal outcome which should not have happened if it had wisely been applied the appropriate health technology to the nature of the disease and the level of care).

Data were analyzed from the software epi info 2000 in its 6.2.4 version.

3. Results Indicators of Death

Over 1675 inpatients, 114 deaths were recorded, but only 72 cases have been the subject of our study. The crude mortality rate is then 4.29%. The highest rates were observed in 2008 (15 cases; 6.91%) and lowest in 2001 (1 case; 0.34%) (Figure 1).

The specific rate of mortality by sex is 63.9% for men and 36.1% for women, which a sex ratio of 1.77.

Age groups who have recorded high rates were: 31-40 years old (20.8%) and 21-30 years (19.4%). The average age was 39 years and the standard deviation 18.5. This rate was low among adults over the age of 70 years (4.2%) (Figure 2).

More than half of the patients who died (51.4%) were without profession, followed by the liberal professions (30.6%).

Cellulitis have been responsible for deaths in 58.33% cases followed by malignant

tumours, Burkitt Lymphoma included (20.83%) (Table 1).

Analysis of the Deaths

The deaths occurred most often within 48 hours after admission in the service (37.50%) (Table 2).

About 65.3% of deaths occurred in the evening and at night, between 6 p.m and 6 a.m.

The circumstances of death were as follows: septic shock (43.05%) and decompensation of severe anemia (16.66%) (Table 3).

These deaths were inevitable in 83.3% of the cases, avoidable in 5.6% of cases and in 11.1% of cases we could not reach a conclusion.

4. Discussion

The hospital mortality during the study period was 4.29% with peaks in the years 1999 (5.66%), 2007 (6.4%) and 2008 (6.91%). This rate seems high compared to that found by Ftouhi et al. 1.56% in internal medicine service in Tunis and Dony et al. 1.1% in surgery service [1] [10] . The study showed a gradual growth of the curve of mortality from 2001 in our service. It is an unsatisfactory trend unlike most hospital services practicing heavy surgery [2] [3] . This high mortality rate could be explained by several factors: the impoverishment of the population in General causing late consultations, the deficit of means of diagnosis and treatment, the lack of maintenance of the existing equipment and the absence of an unit of audit of deaths.

The most affected age groups were those between 31 and 40 years (20.8%) and between 21 and 30 years (19.4%) with an average age of 39 years. It is about young and active people. Elsewhere in Africa, Takongmo [7] and Rakotondrabe [6] found respectively 43 and 33 years in Yaounde and Madagascar, while Proye in Lille, France [1] found an average age of 63 years.

The men were most affected with a sex ratio of 1.77. This result was in line with the excess male mortality found in almost all studies. The majority of the patients who died were without profession (51.4%), it was in general about poor people with difficulties of support. Cellulitis were the leading causes of death (58.33%) followed by the malignancies including lymphoma Burkitt (20.83%). Bakary et al. [11] in a previous study in the same Department had found the cellulitis as being the first cause of hospitalization. These results were almost identical to those of the WHO that classified the causes of mortality as follows in the developing countries by decreasing order: infectious and parasitic diseases, the respiratory system diseases, cancers [12] .

Deaths were more frequent between 6 p.m. and 6 a.m. (65.28%). This period corresponds to the time of activity of the guard team. It was a small team with a doctor, a nurse and an aid who was responsible for inpatients as well as those admitted in an emergency. Sometimes this team is inexperienced and the workload is disproportionate to the size of the team. For Takongmo [7] , who found superposable results, this would allow to accuse a deficiency in the quality of care at the period of guards.

In 37.50% of cases death occurred within 48 hours after admission. This could be explained by the fact that our patients usually arrived in arrays of complications. The traditional treatment of the traditional healers is also an aggravating factor because patients for reasons of insufficient financial mean begin with this kind of treatment.

Septic shock has been the immediate cause of death in 43% of cases followed by decompensated anemia in 16.66% cases. These deaths were preventable in 4 cases (5.6%) and 8 cases (11.1%) the conclusion was impossible. These different situations denote the inadequacy of our intensive care in terms of material and human resources to deal with severe complications of hemodynamic and septic shock [13] .

This study shows some limits; In fact, it is about a retrospective study in which we were confronted to some difficulties. In particular, the bad position of dossiers. So, it would be imperious to establish an audit protocol of death in order to describe them well.

5. Conclusion

The assessment of mortality remains a permanent concern in day-to-day politics of medicine. This study although limited to one single service allows drawing the attention of the medical team on its shortcomings. There is a need to establish a medical audit system in hospitals whose mission will be to improve quality care.
