Abstract:
Background: Skin diseases are a common cause of ill health in developing countries like
Tanzania. The effect of a skin disorder on quality of life of a patient which is ignored many
times is often of more importance than the presence of skin lesions. To adequately meet the
dermatologic needs of the growing population, it is necessary to have a better knowledge
of local skin disease spectrum and their impact on quality of life. This will inform on better
clinical practice and health planning.
Objectives: To describe types of skin diseases, their distribution and impact on quality of
life among medical patients at Muhimbili National Hospital and Muhas Academic Medical
Center (MAMC) in Dar es Salaam, Tanzania.
Methodology: A descriptive hospital based cross-sectional study was conducted from July
2018 to December 2018. All patients admitted to the tertiary dermatology units on account
of skin disease and those attending skin clinic for the first time at the two hospitals were
recruited. A total of 608 patients aged ≥14 years were enrolled. Socio-demographic and
clinical data was collected using a questionnaire. Diagnosis was made on clinical grounds
and laboratory investigations were done whenever necessary. Dermatology life quality
index questionnaire was used to assess the impact of skin disease on quality of life. Data
was analyzed using SPSS version 20.0 and a p-value of ≤ 0.05 with 95% Confidence
interval were considered to be significant. Ethical clearance was sought from MUHAS
ethical committee of research and communication.
Results: There were 580 (95.4%) outpatients of which 56.4% (327/580) were females.
The common diseases among outpatients were atopic dermatitis 31.2%, acne 13.6%,
pityriasis versicolor 8.3% and tinea 7.4%. There were 28 (4.6%) admitted patients of
which 82.1% (23/28) were females and autoimmune disorders (32.1%) was the commonest
diagnosis. The most common reason for admission was severity and extent of illness
(65.4%). The mean length of hospital stay days (SD) was highest in autoimmune disorders
22.18(9.7). Females had significantly high mean dermatology life quality index scores
(SD) than males among outpatients (11.05(6.8) vs 9.58(6.7), p=0.023) as compared to
inpatients (17.9(8.4) vs 15.8 (4.1), p=0.594). Highest mean dermatology life quality index
scores (SD) were seen in inflammatory dermatoses and autoimmune disorders among both
vii
outpatients and inpatients. The proportion of dermatology life quality index scores
(SD)>10 was high among inpatients than outpatients (67.9% vs 47.1%, p=0.012).
Conclusion: Eczematous dermatitis and autoimmune disorders were most common skin
diseases seen among outpatients and inpatients respectively. Different types of skin
diseases varied on effect of quality of life. Further studies are needed to pinpoint root
causes of the disease spectrum and to widen up knowledge on inpatient dermatology.
