Assessment of the needs of critically ill / injured patients' famalies in an accident and emergency unit

The critical illness/injury of a family member warranting an admission to an A&E unit can predispose a family to psychological and physiological needs. The patient-centred-care approach rendered in an A&E unit focuses on the patient as a priority, resulting in the family’s needs being neglected during a crisis situation. Based on the Family Resilience Framework, the aim of this study was to assess the needs of the families of the critically ill/injured patients in an A&E unit. Based on the identified needs, recommendations were made with regard to a family-centred-care approach as a relevant resilience-based strategy suitable to these families. The research adopted a quantitative, non-experimental, exploratory and descriptive design. A purposive convenience sample of 100 participants was recruited over a period of four months. The data were collected by means of a structured interview schedule. The study revealed that the five main domains of family needs identified by the respondents as very important was, in order of priority, the need for communication, support, meaning, comfort and proximity. The findings supported the need to initiate and foster a family-centred-care approach in the A&E unit, which could guide the nurse practitioners in supporting the affected families, which in turn could enable these families to become resilient.

Modelling the relationship between groundwater depth and NDVI using time series regression with Distributed Lag M

Groundwater plays a key role in hydrological processes, including in determining aboveground vegetal growth characteristics and species distribution. This study aimed at estimating time-series data of Normalized Difference Vegetation Index (NDVI) using groundwater depth as a predictor in two land cover types: grassland and shrubland. The study also investigated the significance of past (lagged) groundwater and NDVI in estimating the current NDVI. Results showed that lagged groundwater depth and vegetation conditions influence the amount of current NDVI. It was also observed that first lags of groundwater depth and NDVI were significant predictors of NDVI in grassland. In addition, first and second lags of NDVI were consistently significant predictors of NDVI in shrubland. This shows the importance of vegetation type when modelling the relationship between groundwater depth and NDVI.Keywords: Groundwater depth; Landsat NDVI; Time-series analysis; Distributed Lag Model

Integration of ICT into Education: Lessons Learnt at the State University of Zanzibar and the Midlands State University in Zimbabwe

The provision of education using ICT has been adopted by many institutions in Africa. The use of ICT is critical in knowledge-based societies such as those in Zanzibar and Zimbabwe. This study looks at how the Midlands State University (MSU) and State University of Zanzibar (SUZA) have adopted the use of ICT in many ways. ICTs do not work for everyone in the same way. It has become inevitable, in the current digital era for educators to integrate ICT in their teaching and gradually replace traditional teaching methods with modern ones which are ICT led. The main objective of this study is to find out challenges and opportunities of using ICT in education

Medication omissions in the first 48 hours after admission: failure in prescribed medicines reaching in-patients in paediatrics wards at the University Teaching Hospitals, Children’s Hospital in Lusaka, Zambia

Background: The first few days of in-patient care are possibly the most significant in a patient’s recovery and any omitted medications during this period may harm the patient or increase their hospital length of stay. Therefore, our study aimed at assessing the frequency of medication administration omission errors and their reasons for the omission in the paediatric wards after admission at University Teaching Children’s Hospital.Methods: This was a descriptive study in which 259 patient files and drug charts were reviewed. Admission prescription charts were studied in detail over a period of four weeks and all drugs prescribed but then not given in the first 48 hours were recorded as omitted medications, along with the reason given for their omission.Results: From the 259 drug charts, a total of 1598 doses of drugs were ordered within 48 hours of admission. However, from this, only a total of 1132 doses were administered with the remaining 466 doses omitted, which accounted for a frequency of 29.2%. When the frequency of medication omission errors was compared, parenteral drugs (70.8% vs. 25.3%, [p=0.0001]), afternoon shift (48.5% vs. 15.8%, [p=0.0001]), and anti-infective medications (69.1% vs. 39.4%, [p=0.0001]) were found to be the most frequently omitted medications. There were also considerably more medication omissions in patients prescribed with more medications (median number: 4, I QR [2, 6] vs. median number: 2, IQR [2, 4], [p=0. 0.001]). The most common reason for the omission was medication unavailability (89.3%), followed by work overload (71.4%), and the patient is off the ward (71.4%).Conclusions: This study revealed that medication omissions are a continuing problem and this may result in increased morbidity and mortality rates. There is a need to put in place specific strategies to reduce this problem.

Temporal Trends and Predictors of Modern Contraceptive Use in Lusaka, Zambia, 2004-2011.

INTRODUCTION: Although increasing access to family planning has been an important part of the global development agenda, millions of women continue to face unmet need for contraception. MATERIALS AND METHODS: We analyzed data from a repeated cross-sectional community survey conducted in Lusaka, Zambia, over an eight-year period. We described prevalence of modern contraceptive use, including long-acting reversible contraception (LARC), among female heads of household aged 16-50 years. We also identified predictors of LARC versus short-term contraceptive use among women using modern methods. RESULTS AND DISCUSSION: Twelve survey rounds were completed between November 2004 and September 2011. Among 29,476 eligible respondents, 17,605 (60%) reported using modern contraception. Oral contraceptive pills remained the most popular method over time, but use of LARC increased significantly, from less than 1% in 2004 to 9% by 2011 (p < 0.001). Younger women (OR: 0.46, 95% CI: 0.34, 0.61) and women with lower levels of education (OR: 0.70, 95% CI: 0.56, 0.89) were less likely to report LARC use compared to women using short-term modern methods. CONCLUSIONS: Population-based assessments of contraceptive use over time can guide programs and policies. To achieve reproductive health equity and reduce unmet contraceptive need, future efforts to increase LARC use should focus on young women and those with less education

Improving pathways to care through interventions cocreated with communities: a qualitative investigation of men’s barriers to tuberculosis care-seeking in an informal settlement in Blantyre, Malawi

Introduction Men have a higher prevalence of undiagnosed tuberculosis (TB) than women and can spend up to a year longer contributing to ongoing transmission in the community before receiving treatment. Health outcomes are often worse for patients with TB living in informal settlements especially men. This study aimed to understand the barriers preventing men from seeking care for TB and cocreate interventions to address these barriers. Methods We used qualitative research methods including in-depth interviews and participatory workshops. Researchers worked with women and men living in Bangwe, an informal settlement in Blantyre, Malawi to develop interventions that reflected their lived realities. The study took place over two phases, in the first phase we undertook interviews with men and women to explore barrier to care seeking, in the second phase we used participatory workshops to cocreate interventions to address barriers and followed up on issues emerging from the workshops with further interviews. In total, 30 interviews were conducted, and 23 participants joined participatory workshops. The team used a thematic analysis to analyse the data. Results Three interconnected thematic areas shaped men’s health TB seeking behaviour: precarious socioeconomic conditions; gendered social norms; and constraints in the health system. Insecurity of day labour with no provision for sick leave; pressure to provide for the household and a gendered desire not to appear weak and a severely under-resourced health system all contributed to men delaying care in this context. Identified interventions included improved patient–provider relations within the health-system, improved workers’ health rights and broader social support for households. Conclusion Improving mens’ pathways to care requires interventions that consider contextual issues by addressing individual level socioeconomic factors but also broader structural factors of gendered social dynamics and health systems environment

Bacterial vaginosis and the risk of trichomonas vaginalis acquisition among HIV-1 negative women.

Centre for the AIDS Programme of Research In South Africa.Background: The vaginal microbiota may play a role in mediating susceptibility to sexually transmitted infections, including Trichomonas vaginalis (TV). Methods: Data were analyzed from HIV-1-seronegative women participating in HIV Prevention Trials Network Protocol 035. At quarterly visits for up to 30 months, participants completed structured interviews and specimens were collected for genital tract infection testing. T. vaginalis was detected by saline microscopy. Bacterial vaginosis (BV) was characterized by Gram stain using the Nugent score (BV = 7Y10; intermediate = 4Y6; normal = 0Y3 [reference group]). Cox proportional hazards models stratified by study site were used to assess the association between Nugent score category at the prior quarterly visit and TV acquisition. Results: In this secondary analysis, 2920 participants from Malawi, South Africa, United States, Zambia, and Zimbabwe contributed 16,259 follow-up visits. Bacterial vaginosis was detected at 5680 (35%) visits,and TV was detected at 400 (2.5%) visits. Adjusting for age, marital status, hormonal contraceptive use, unprotected sex in the last week and TV at baseline, intermediate Nugent score, and BVat the prior visit were associated with an increased risk of TV (intermediate score: adjusted hazard ratio [aHR], 1.73; 95% confidence interval [CI], 1.21Y2.19; BV: aHR, 2.40; 95% CI, 1.92Y3.00). Sensitivity analyses excluding 211 participants with TV at baseline were similar to those from the full study population (intermediate score: aHR, 1.54; 95% CI, 1.10Y2.14; BV: aHR, 2.23; 95% CI, 1.75Y2.84). Conclusions: Women with a Nugent score higher than 3 were at an increased risk for acquiring TV. If this relationship is causal, interventions that improve the vaginal microbiota could contribute to reductions in TV incidence

Risk Factors of Porcine Cysticercosis in the Eastern Cape Province, South Africa

There is a high prevalence of Taenia solium taeniosis/cysticercosis in humans and pigs in the Eastern Cape Province (ECP) of South Africa. The objective of this study was to identify risk factors of porcine cysticercosis in select districts of the ECP. Data were collected in 2003 by interviewing 217 pig producers from the area. Blood samples were collected from 261 of their pigs, which were tested using two enzyme-linked immunosorbent assays (ELISA) for the presence of antibodies to cysticercosis. Frequencies of both owner- and pig-level characteristics were determined. For pig-level analysis, all bivariable and multivariable associations were determined using the surveylogistic procedure of the SAS/STAT® software to accommodate for the intraclass correlation that exists for clusters of pigs within one owner and for clusters of owners within a district. All tests for significance were performed at the α = 0.05 level, and adjusted odds ratios (aOR) and 95% confidence intervals (CI) were determined. Among the respondents, 48% of their households lacked a latrine, 98% slaughtered pigs at home, and 99% indicated that meat inspection services were not available. On bivariable analysis, there was a significant association between porcine infection and district (p = 0.003), breed (p = 0.041) and the absence of a latrine (p = 0.006). On multivariable analysis, the absence of a latrine was the only variable significantly associated with porcine infection (aOR = 1.89; 95% CI = 1.07, 3.35) (p = 0.028). The increased odds of porcine infection with households lacking a latrine contributes to our understanding of the transmission of this parasite in the ECP. Determining and addressing the risk factors for T. solium infection can potentially lower the very high prevalence in humans and pigs in this endemic area

Marked Reduction in Prevalence of Malaria Parasitemia and Anemia in HIV-Infected Pregnant Women Taking Cotrimoxazole With Or Without Sulfadoxine-Pyrimethamine Intermittent Preventive Therapy during Pregnancy in Malawi

Background. Effectiveness of cotrimoxazole (CTX) compared with sulfadoxine-pyrimethamine (SP) intermittent-preventive-therapy (IPTp) for malaria in HIV-infected pregnant women is unknown. We examined effectiveness of CTX with or without SP-IPTp versus SP-IPTp at reducing malaria parasitemia and anemia
