Occupational injury prevalence and predictors among small-scale sawmill workers in the Sokoban Wood Village, Kumasi, Ghana.

BACKGROUND: Sawmill workers are at increased risk of occupational injuries due to their exposure to workplace hazards. However, little is known about the burden of occupational injuries among them in Ghana. Understanding its prevalence and associated factors is necessary to design appropriate interventions to improve workers' health and safety. This study sought to determine the prevalence and factors associated with occupational injuries among small-scale sawmill workers at Sokoban Wood Village, Kumasi. METHODS: A cross-sectional study was conducted among 138 small-scale sawmill workers from December 2020 to January 2021. Data was collected on demographic and work-related characteristics including age, sex, personal protective equipment (PPE), workspace design, and lighting. The primary outcome was the prevalence of occupational injuries in the 12 months preceding the survey. Logistic regression method was used to assess for independent predictors of occupational injuries, and associations were deemed statistically significant at p < 0.05. RESULTS: Approximately 66.7% of the workers experienced occupational injuries within the 12 months preceding the study. Cuts (69.6%) were the most commonly reported injuries. Injuries were mainly caused by machine parts/sharp objects (47.8%) and being hit by logs/objects (46.8%). Only 40.7% of the workers reported always using PPE while legs (38.0%) and hands (37.0%) were the most common body parts injured. The worker's monthly income, poor workspace design and poor lighting had increased odds of occupational injuries while an increase in age was associated with a 5% decreased odds of occupational injuries. CONCLUSION: The prevalence of occupational injuries among the sawmill workers at the Sokoban Wood Village was high, and this calls for prioritization of health and safety at the workplace. Essential measures required include improvements in the safety of machine tools, workspace design and lighting.

Prevalence and associated factors of occupational injuries in an industrial city in Ghana.

BACKGROUND: Workers are exposed to workplace hazards which increase their risk of occupational injury. Data on occupational injuries and associated factors are important for planning and informing national policy regarding workplace health and safety. This study sought to estimate the prevalence and factors associated with occupational injuries among workers in an industrial city in Ghana. METHODS: A community-based cross-sectional survey was conducted among 459 workers in the Tema industrial enclave in Ghana from 22nd December 2020 to 27th February 2021. Participants were recruited using a two-stage sampling technique. Eight communities were randomly selected from twenty-five communities in the first stage while households in each community were randomly selected in the second stage. Data on socio-demographic characteristics, occupational health and safety and occupational injuries were collected. Logistic regression was used to examine the relationship between occupational injuries and associated factors. RESULTS: The mean age of the workers was 33.9 (±6.8) years with a range of 21-53 while over 18.1% of them were working at the Port and Harbour. The prevalence of occupational injury among the workers in the preceding twelve months was 64.7%. The mechanism of injury was mainly the use of working tools (45.8%) and hot surfaces, substances or chemicals (14.1%). Being a casual staff (AOR: 2.26, 95%CI: 1.04-4.92), working at Port and Harbour (AOR: 3.77, 95%CI: 1.70-8.39), no health and safety training (AOR: 2.18, 95%CI: 1.08-4.39), dissatisfaction with health and safety measures (AOR: 4.31, 95%CI: 2.12-8.78) and tertiary education (AOR: 0.03, 95%CI: 0.01-0.10) were significantly associated with occupational injuries. CONCLUSION: The prevalence of occupational injuries in this study was high. Promoting machine tools' safety, health and safety training, and satisfaction with health and safety measures through rewarding workers who do not sustain injuries could be key to employees' health and safety.

Contamination of groundwater by petroleum hydrocarbons: Impact of fuel stations in residential areas.

Anthropogenic factors such as leakages from fuel storage facilities contribute to the release of petroleum hydrocarbons into groundwater. Following the proliferation of fuel stations in residential areas, this research assessed physicochemical parameters, salinity, and levels of total petroleum hydrocarbons (TPH) in groundwater sources within selected residential areas. From the study, mean values of temperature (30.5 °C), pH (5.8), EC (181.5 µs/cm), TDS (90.7 mg/L), and salinity (0.1 ppm) were recorded. The highest mean concentration of TPH (9.5 mg/L) was recorded at location A, while three sampling points (J, L, and M) exhibited 0.0 mg/L. Notably, TPH concentrations exceeding permissible limits were observed at three sampling points (A, B, and R). Strong positive correlations were observed between EC and TDS (r = 0.9), as well as salinity and EC (r = 0.9) and TDS (r = 0.9). Matrix plots demonstrated non-linear relationships, except for TDS and EC, although TPH and temperature exhibited a slightly linear pattern. The distance from USTs to the groundwater sources varied in the area. At location H, this distance (25 m) was measured as the shortest, where the mean TPH concentration was 3.71 mg/L. However, site Q exhibited the longest distance of 535 m, accompanied by a mean TPH concentration of 1.1 mg/L. Though the proximity of USTs to groundwater sources exerted some level of influence on the groundwater system, multiple linear regression, ANOVA, and cluster analysis showed that this did not pose direct and major impacts on the concentrations of TPH. However, approaches are needed to remediate the affected groundwater sources.

Spatial distribution of potentially toxic elements in e-waste contaminated site at Akwatia-Line, Kumasi, Ghana.

E-waste processing sites abound with potentially toxic elements (PTE) that negatively affect the environment and human health. The study determined the presence of selected PTE (Cu, Zn, Pb, Hg, and Al) and their spatial distribution in an e-waste processing site in a developing country setting. pH, moisture, organic matter/carbon, and particle size were determined in 30 soil samples. The spatial position of each sampling point was picked with a GPS device, and the area was mapped in a GIS environment. The concentrations of PTE were determined with an atomic absorption spectrophotometer. Findings from the study indicate that the soil is polluted with PTE, rich in organic carbon/matter but has low pH. The Geoaccumulation Indices ranged from unpolluted (Al) to strongly/extremely polluted (Cu). Pollution Load Index showed about 77 % of the samples as extremely/heavily polluted, 10 % as heavily polluted, and 13 % as moderately polluted. Contamination Factors of Zn, Pb, and Cu were very high but considerably low for Hg and Al. Regular monitoring and remediation are required for the soil to be restored and put into productive use.

Prevalence and determinants of occupational injuries among emergency medical technicians in Northern Ghana.

BACKGROUND: Emergency Medical Technicians (EMTs) are the primary providers of prehospital emergency medical services. The operations of EMTs increase their risks of being exposed to occupational injuries. However, there is a paucity of data on the prevalence of occupational injuries among EMTs in sub-Saharan Africa. This study, therefore, sought to estimate the prevalence and determinants of occupational injuries among EMTs in the northern part of Ghana. METHODS: A cross-sectional study was conducted among 154 randomly recruited EMTs in the northern part of Ghana. A pre-tested structured questionnaire was used to collect data on participants' demographic characteristics, facility-related factors, personal protective equipment use, and occupational injuries. Binary and multivariate logistic regression analyses with a backward stepwise approach were used to examine the determinants of occupational injuries among EMTs. RESULTS: In the 12 months preceding data collection, the prevalence of occupational injuries among EMTs was 38.6%. Bruises (51.8%), and sprains/strains (14.3%) were the major types of injuries reported among the EMTs. The key determinants of occupational injury among EMTs were male sex (AOR: 3.39, 95%CI: 1.41-8.17), an absence of a health and safety committee at the workplace (AOR: 3.92, 95%CI: 1.63-9.43), absence of health and safety policy at the workplace (AOR: 2.76, 95%CI: 1.26-6.04) and dissatisfaction with health and safety measures at the workplace (AOR: 2.51, 95%CI: 1.10-5.71). CONCLUSION: In the twelve months before to the data collection for this study, the prevalence of occupational injuries among EMTs of the Ghana National Ambulance Service was high. The creation of health and safety committees, the creation of health and safety rules, and the strengthening of current health and safety procedures for EMTs are all possible ways to lessen this.

Determinants of burnout among nurses and midwives at a tertiary hospital in Ghana: A cross-sectional study.

AIM: This study determined the prevalence and key determinants of burnout among nurses and midwives in Kumasi, Ghana. DESIGN: Hospital-based cross-sectional study. METHOD: A questionnaire was used to obtain data from 391 nurses and midwives at a tertiary hospital in Kumasi, Ghana using simple random sampling. RESULTS: About 84.4% of the participants were females. The majority of the study participants experienced low burnout for all dimensions (58% in emotional exhaustion, 55.5% poor personal accomplishment and 38.3% depersonalization). Multiple regression analysis revealed that high emotional exhaustion was independently predicted by post-graduate education (ß = 6.42, p = .003), lack of support from management (ß = 2.07, p = .024), dislike for leadership style, (ß = 3.54, p < .001) and inadequate number of staff (ß = 2.93, p = .005). Age (ß = 0.35, p = .004), lack of support from management (ß = 1.60, p = .012), and inadequate number of staff (ß = 1.49, p = .034) independently predicted high depersonalisation. Female sex (ß = 4.36, p < .001) and years of practice (ß = -0.26, p < .001) independently predicted low personal accomplishment.

Factors Influencing Turnover Intention among Nurses and Midwives in Ghana.

Background: Nurse turnover intention, defined as a measure of nurses' desire to leave their positions, is a global public health issue with a grave impact on the healthcare workforce. However, literature on it is limited in sub-Saharan Africa, an at-risk region. This study aimed to determine the predictors of turnover intention among nursing staff at a tertiary hospital in Kumasi, Ghana. Methods: This was an institution-basedcross-sectional study conducted among 226 randomly selected nurses and midwives working at a tertiary healthcare center in Kumasi, Ghana. Data were collected by using a structured questionnaire. Significant predictors of turnover intention were analyzed by using multivariate logistic regression analysis. Adjusted odds ratio (AOR) with a 95% confidence interval (CI) and p value <0.05 was used. Results: The prevalence of turnover intention among study participants was 87.2% (197/226). About two-thirds (61.5%, 139/226) of the participants were exposed to a high level of workplace hazards. Management support (AOR = 3.09, 95% CI = 1.09-8.75), salary (AOR = 0.07, 95% CI = 0.01-0.46), inadequate number of staff on duty per shift (AOR = 3.36, 95% CI = 1.08-10.47) and participants' rank (AOR = 6.81, 95% CI = 1.18-39.16) were significantly associated with turnover intention. Conclusion: Overall, the turnover intention was high. Hence, there is a need for policymakers, health administrators, and nurse managers to implement strategies such as increasing staff strength, providing adequate support, incentives, and other forms of motivation for nurses and midwives to help reduce the rate of turnover intention.

Attrition of Nursing Professionals in Ghana: An Effect of Burnout on Intention to Quit.

Background: Burnout among nursing professionals at the workplace and how it influences their decision to quit the profession is crucial to the delivery of quality health service. The shortage of nursing professionals has serious consequences on the healthcare system. Aim: To examine the effect of burnout on intention to quit the profession among nursing professionals. Methods: A cross-sectional study among 375 randomly selected nursing professionals in active service at a tertiary healthcare setting in Kumasi, Ghana. The Maslach Burnout Inventory was used to determine burnout, and their intention to quit the profession was assessed by asking participants whether they ever thought about quitting the profession in the past 12 months. The effect of burnout on intention to quit was analyzed using logistic regression analysis. Results: The overall prevalence of burnout among participants was 2.1% (8/375) with 10.1% (38/375), 24.0% (90/375), and 56.3% (211/375) experiencing high emotional exhaustion, depersonalisation, and low personal accomplishment, respectively. Nearly half (49.3%, 185/375) of the participants had intention to quit the profession. Emotional exhaustion (adjusted odds tatio, AOR = 5.46; 95% CI = 2.25-13.20), depersonalisation (AOR = 1.77 95% CI = 1.07-2.95), and personal accomplishment (AOR = 2.27; 95% CI = 1.30-3.96) were associated with intention to quit the profession. Conclusion: Burnout has a negative effect causing intention to quit nursing profession. It is imperative to identify strategies such as occupational health surveillance that will aim at reducing the incidence of burnout at the workplace due to its consequences, one of them being the intention to quit.

Post COVID-19 recovery: Challenges and opportunities for solid waste management in Africa.

The current COVID-19 pandemic has significantly altered the quantity and composition of waste generated on the African continent. This new phenomenon, coupled with the indiscriminate disposal of used personal protective equipment (PPEs), poses serious challenges to local authorities, most of whom have limited experience or lack the strategy to handle this occurrence. These PPEs, like the face masks, are made up of polymeric materials that are liquid resistant and remain for a long time in the environment after discard. Thus, they are considered as a significant source of plastic pollution in the environment. Notwithstanding the environmental challenges associated with COVID-19, if Africa is to be ready for the expected growth in waste generation and variation in waste composition in the coming century as predicted by the African waste management outlook report in 2018, she has to have a renewed focus and seize the unique opportunities that COVID-19 presents. The continent has to indulge in introspection of its shortfalls in managing waste and consciously make efforts that would ensure social and technological innovation and investment in services and infrastructure in the waste and secondary resources sector than never before seen in Africa. This approach would help the continent achieve its waste management vision of extending regular and reliable waste collection services to all while valorizing waste generated. This critical review paper reveals the silver lining in the dark cloud of the COVID-19 pandemic by highlighting some of the noticeable environmental challenges in Africa due to the current pandemic and elucidating the rare opportunities that African countries can harness to improve the waste management sector.

Levels of Lead, Copper, and Zinc in Cabbage (Brassica oleracea sp.) and Lettuce (Lactuca sativa sp.) Grown on Soil Amended with Sewage Sludge.

The study focused on levels of selected heavy metals (Pb, Zn, and Cu) in sewage sludge, soil, and in lettuce and cabbage grown on sewage sludge amended soil. Also, the effect of sewage sludge on soil properties (pH, soil organic matter, and soil conductivity) was studied. Three treatments were used based on nitrogen application rates of the sewage sludge: 100, 150, and 200 kg N/ha for lettuce while 160, 210, and 260 kg N/ha for cabbage. A pot experiment was conducted with pots arranged in a completely randomized design and under local climatic conditions. The study revealed that soil organic matter content and conductivity increased significantly with increasing nitrogen application rates. Levels of heavy metals in the soil increased significantly with increasing application rates. The controls for both plants recorded the lowest heavy metal uptake. Cabbage had an uptake of 0.48 ± 0.13, 1.36 ± 0.23, and 2.60 ± 0.29 mg/kg for Pb, Zn, and Cu, respectively, while lettuce had 0.34 ± 0.19, 1.35 ± 0.31, and 2.30 ± 0.14 mg/kg uptake for Pb, Zn, and Cu, respectively. Highest metal uptake was recorded at the highest application rate in both plants (0.66 ± 0.17, 2.66 ± 0.09, and 4.33 ± 0.14 mg/kg for Pb, Zn, and Cu, respectively, for cabbage and 0.54 ± 0.01, 2.24 ± 0.17, and 3.88 ± 0.19 mg/kg of Pb, Zn, and Cu, respectively, for lettuce). The uptake of Zn and Cu was significant, while Pb uptake was insignificant for both plants. Yields increased significantly with increasing application rates. The study provides information on yield enhancement resulting from cultivating plants on soil amended with sewage sludge and the associated health risk implication.

Potential sites for landfill development in a developing country: A case study of Ga South Municipality, Ghana.

Landfilling, which sits at the bottom of the waste management hierarchy, is the most employed option for managing waste in many emerging economies. In view of the numerous environmental and public health challenges associated with operation of landfills, proper siting would require inputs that overcome the challenges. This study sought to use Geographic Information System application through multi-criteria decision technique to spatially locate suitable sites that fulfill standard landfill guidelines, for waste disposal. Spatial Analyst extension within ArcGIS software was employed for the suitability analysis. Three processes were involved: (1) digitizing to determine boundaries around built up areas, (2) buffering for proximity analysis in order to generate zones around features such as roads, streams, etc. and (3) overlay analysis to determine areas suitable for landfilling. The findings from this study revealed that about 2.62% of the total area was considered as most suitable for landfilling, 2.74% deemed suitable and a large portion (94.64%), considered unsuitable. The study identified 6 most suitable sites that can be used for landfill development in the study area burdened with urbanization. GIS has been used to determine suitable sites for landfill development. Findings from the study serve as guideline for environmentally friendly landfill siting with efficient land-use planning.
