Patient Preference and Adherence | Year: 2016
Background: Patient expectations have been recognized as a factor for patient satisfaction in medical consultations. Although various studies explored the relationship between patient expectations and patient satisfaction in developed countries, there is a lack of research evidence in Ethiopia where the meeting of patient expectations could relate to satisfaction. Objective: To assess the relationship between patients’ expectations and their satisfaction in the consultation of patients at the outpatient department. Study design: Data were collected regarding preconsultation expectations and postconsultation experiences of adult patients attending nine public hospitals. A systematic random sampling method was used where every fifth patient attending an outpatient department was selected. The patients were interviewed before consultation and after consultation to assess whether their pre-consultation expectations were met and to assess how satisfied they were with the consultation. Cronbach’s alpha statistic was used to assess the reliability of the expectation questionnaires, and paired t-test was used to assess any differences between previsit expectations and postvisit experiences. Logistic regression techniques were used to assess variables considered as independent factors for patient satisfaction. Results: A total of 776 patients were interviewed, giving a response rate of 92.3%. About 93.7% mentioned a diagnosis for their condition as a reason for their current hospital visits. There is a significant difference between preconsultation expectation and postconsultation expectation. Postconsultation expectation, perceived health status, and perceived control on health were factors identified as increasing patient satisfaction. In addition, the presence of any disappointments or worries, previous experience in health care, and extent of influence on the consultation had a negative influence on satisfaction. Conclusion: Postconsultation expectation impacts patient satisfaction. Health care service providers should emphasize the actual experience of consultation. © 2016 Berhane and Enquselassie.

This 90 days vermicomposting work was conducted to evaluate the performance of epigeic earthworms E.andrei to alter and change four commonly dumped and littered solid wastes in Ethiopian cities and towns in to a high quality vermicompost. All wastes were mixed with cow dung in 3:1 ratio and treated with earthworm E.andrei in the following waste and worm mass proportion. 9kg of vegetable waste treated with 130gm of worms, 9kg of enset waste treated with 130gm of worms, 5kg of coffee husk treated with 70gm of worms, 8kg of khat waste treated with 115gm of worms. Results from all beddings treated by this species of earthworms showed that TKN increased b/n 50.3 - 56%, TK increased between 29.6 - 43.6 %, TP increased between 58.9% - 73.2%, Ca increased between 39.6 % - 61.5%, while TOC decreased between 35% - 38.4 % and the C:N ratio reduced between 60 - 68 %. The findings from this experiment generally indicated that vermicomposting could be one good option to improve solid waste management performance of Ethiopian cities and towns through the production of excellent biofertilizer for agronomic purpose.

The cost of nutrient media is the major challenge for biomass production of Spirulina. Although much effort has been made to use enriched seawater for the cultivation of this microalga, little attention has been given to the potential of water of soda lakes. In this study, growth (μ, day-1) and biomass production (B) of Arthrospira fusiformis cultivated using waters of the soda lakes Chitu and Shala with or without supplementation were evaluated. Comparable μ and B values were achieved in both Lake Chitu water-based media (CBM) and Lake Shala water-based media (SBM), with slightly higher values in the latter. Both CBM and SBM supplemented with the standard Spirulina medium (SM) by 25 % and 50 % supported considerably higher μ and B. The pH and salinity of the cultures showed significant variations (P < 0.05) among the media and had considerable effect on μ and B. The observed higher μ and B were probably associated with the reduction in pH and salinity of the supplemented media due to addition of bicarbonate-carbonates and dilution, and provision of the limiting nutrient nitrogen. The higher μ and B in SBM may have resulted from some of their aggregate chemical parameters, which were closer to those in the SM, and abundant PO4-P. This seems to suggest that Lake Shala water is more conducive to Arthrospira. We contend that 25 % and 50 % supplemented Lake Shala water can be preferably used to produce Arthrospira biomass, thereby reducing the cost of nutrients by 75 % and 50 %, respectively. © 2014 Springer Science+Business Media Dordrecht.

Although variability of Arthrospira morphology, widely used in taxonomy and other valuable aspects, as a response to changes in environmental variables has been studied in laboratory cultures, little is known about such responses in the natural habitats. In this study, Arthrospira fusiformis was characterized morphologically in relation to selected environmental variables in the natural ecosystem. Three distinct morphotypes, tightly coiled (H-type), spiral or loosely coiled (S-type), and intermediately coiled (C-type) were observed and described. They varied largely in the degree of coiling, trichome and helix dimensions, coils, shape of trichome end and trichome abundance. The H-type was the most dominant (50%) followed by the S-type (40%). The dominance of H-type and tightening of helix pitch were strongly associated with NO3 - and HCO3 - deficiencies, and high levels of photosynthetically active radiation (PAR) and temperature of the lake. The abundance of S-type was more strongly but negatively related to the high salinity of the lake, probably indicating that decreasing salinity may favor the S-type. In conclusion, the variability in abundance and morphology seem to suggest that A. fusiformis could show morphological modifications in response to environmental stresses in their natural soda lakes, resulting in occurrence of various morphotypes of the same species. © 2014 Springer International Publishing Switzerland.

Introduction. Health care workers are exposed to different kinds of occupational hazards due to their day to day activities. The most common occupational exposure like body fluids is a potential risk of transmission of blood-borne infection like human immunodeficiency virus.Objective. To assess the prevalence and determinants of occupational exposure to human immunodeficiency virus infection.Methods and Materials. A descriptive cross-sectional institution based study was conducted in selected four health institutions in Debre Berhan town. Quantitative and qualitative data were collected using semistructured interviewer administered questionnaire. The frequency distribution of dependent and independent variables was worked out and presented using frequency table, graph, and chart.Result. The overall prevalence of occupational exposure of the health care workers was found to be 88.6% (n = 187) in the past 12 months. Contact to potentially infectious body fluids accounts for the largest proportion (56.7%) followed by needle stick injury (31.5%) and glove breakage (28.8%).Conclusion. In this study majority (88.6%) of the health care workers had a risky occupational hazard that exposed them to human immunodeficiency virus infection during the past 12 months. The statistically significant determinant factors were professional status, working room, and time of personal protective equipment usage. © 2014 Filmawit Aynalem Tesfay and Tesfa Dejenie Habtewold.

Depression Research and Treatment | Year: 2015
Background. The emotional consequences of diabetes have been scrutinized by a number of investigative teams and there are varying reports about the association of depression with type 2 diabetes mellitus. However, there is limited data about this in Ethiopia. Therefore, the purpose of this study was to assess the prevalence of comorbid depression among type 2 diabetic outpatients. Methods and Materials. Institution based cross-sectional study design was conducted on a random sample of 276 type 2 diabetic outpatients from Black Lion General Specialized Hospital. Systematic random sampling technique was used to get these individual patients from 920 type 2 diabetic outpatients who have an appointment during the data collection period. Patients' depression status was measured using Patient Health Questionnaire 9 (PHQ 9). Result. Totally 264 type 2 diabetic outpatients were interviewed with a response rate of 95.6%. The prevalence of depression among type 2 diabetic outpatients was 13%. Based on PHQ 9 score, 28.4% (75) fulfilled the criteria for mild depression, 12.1% (32) for moderate depression, 2.7% (7) for moderately severe depression, and 1.5% (4) for severe depression. But 45.8% (121) of patients had no clinically significant depression. Conclusion. This study demonstrated that depression is a common comorbid health problem in type 2 diabetic outpatients with a prevalence rate of 13%. © 2015 Tesfa Dejenie Habtewold et al.

Reproductive Health | Year: 2014
Background: Ethiopia is the second most populous country in Africa with high fertility and fast population growth rate. It is also one of the countries with high maternal and child mortality rate in sub-Saharan Africa Family planning is a crucial strategy to halt the fast population growth, to reduce child mortality and improve maternal health Millennium Development Goal 4 and 5. Therefore, this study aimed to assess the prevalence and determinants of modern contraceptive utilization among married women of reproductive age group. Methods. A community based cross-sectional study was conducted from August 15 to September 1, 2010 among married women aged 15-49 years in Debre Birhan District. Multistage sampling technique was used to select a total of 851 study participants. A pre-tested structured questionnaire was used for gathering data. Bivariate and multivariate logistic regression analyses were performed using SPSS version 16.0 statistical package. Results: Modern contraceptive prevalence rate among currently married women was 46.9%. Injectable contraceptives were the most frequently used methods 62.9%, followed by intrauterine device 16.8%, pills 14%, norplant 4.3%, male condom 1.2% and female sterilization 0.8%. Multiple logistic regression model revealed that the need for more children AOR 9.27, 95% CI 5.43-15.84, husband approve AOR 2.82, 95% CI 1.67-4.80, couple's discussion about family planning issues AOR 7.32, 95% CI 3.60-14.86. Similarly, monthly family income and number of living children were significantly associated with the use of modern contraceptives. Conclusion: Modern contraceptive use was high in the district. Couple's discussion and husband approval of contraceptives use were significantly associated with the use of modern contraceptives. Therefore, district health office and concerned stakeholders should focus on couples to encourage communication and male involvement for family planning. © 2014 Mohammed et al.; licensee BioMed Central Ltd.

Background: Diarrheal disease is widely recognized as a major cause of child morbidity and mortality in developing countries, particularly in sub-Saharan Africa including Ethiopia. There exist variations in explanatory variables of diarrhea depending on the context of the study. Objective: To examine the effects of selected environmental, socio-economic and behavioral factors on childhood diarrhea in Mecha District, West Gojjam, Ethiopia. Methods: A community based cross-sectional study was carried out in February 2009. A proportionate stratified random sampling technique was used to select 768 households that had at least one under-five child. Data was collected using a pre-tested structured questionnaire by trained data collectors. Bivariate and multivariate logistic regression analyses were undertaken to identify predictors of childhood diarrhea. Results: The prevalence of diarrhea among mothers and under-five children was 8.2% and 18.0%, respectively. Maternal education (AOR=5.6, 95% CI: 1.5-19.4), maternal history of recent diarrhea (AOR, 5.5; 95% CI, 2.9-9.8), availability of latrine facility (AOR, 1.9; 95% CI, 1.1-3.4), duration of breast feeding (AOR=2.7, 95% CI: 1.1-7.3), and age of the child (AOR=2.8; 95% CI: 1.3-5.9) had a significant association. Conclusion: From this study, variation in the level of diarrheal morbidity is well explained by maternal factors and presence of latrine facility. Educating mothers focusing on sustained behavioral changes in the use of latrine integrated with personal hygiene is an important intervention for the prevention and control of diarrhea among children.

The species composition, distribution and diversity of macrophytes in Lake Ziway were determined at the end of dry and wet seasons along nine littoral sites during 2010 using a belt transect method. Some physicochemical parameters were also measured. Fourteen macrophyte species were identified with low species diversity for the lake (H' value of 1.805). The macrophyte species composition of the lake has undergone many changes during the last few decades. Arundo donax, which was never reported earlier, attained the highest relative density (30.7%) and frequency (30.5%) in this study, followed by Echinochloa colona, Potamogeton schweinfurthii, Cyperus articulatus, Typha latifolia and Cyperus papyrus. The average densities of A.donax, C.articulatus, E.colona and Pistia stratiotes were positively correlated with nutrients, whereas the density of the other species had negative correlation with physicochemical variables (CCA). Generally, the present macrophyte composition and abundance indicates healthy ecological condition of the lake. But if nutrient levels continue to increase and water levels continue to decline, we expect further changes in macrophyte composition and especially a shift towards invasive floating species. © 2012 Blackwell Publishing Ltd.
