A study on usefulness of a set of known risk factors in predicting maternal syphilis infections in three districts of Western Province, Zambia

Introduction: Despite roll-out of cost-effective point-of-care tests, less than half antenatal attendees in rural western Zambia are screened for syphilis. This study formulated a clinical, risk-based assessment criteria and evaluated its usefulness as a non-biomedical alternative for identifying high-risk prenatal cases. Methods: We conducted a cross-sectional survey of antenatal clinic attendees in Kaoma, Luampa and Nkeyema districts to collect data on exposure to nine pre-selected syphilis risk factors. These factors were classified into major and minor factors based on their observed pre-study association strengths to maternal syphilis. Clinical disease was defined as exposure to either two major factors, one major with two minor factors or three minor factors. Sensitivity, specificity and predictive values of the clinical protocol were then calculated in comparison to rapid plasmin reagin results. Results: The observed syphilis prevalence was 9.3% (95% CI: 7.4 - 11.6%) and the overall sensitivity of the study criteria was 62.3% with positive predictive value of 72.9%. Sensitivities of individual case-defining categories were even lower; from 17.4% to 33.3%. Results confirmed that abortion history, still birth, multiple sexual partners, previous maternal syphilis infection, partner history of sexually transmitted infection and maternal co-morbid conditions of HIV and genital ulcer disease were significantly associated to maternal syphilis in study population as well. Conclusion: The criteria was not as effective as biomedical tests in identifying maternal syphilis. However, it could be a useful adjunct/alternative in antenatal clinics when biomedical tests are either inadequate or unavailable.Pan African Medical Journal 2016; 24

Establishing common leadership practices and their influence on providers and service delivery in selected hospitals in Lusaka province, Zambia

In an evolving health care environment, hospitals need managers with high levels of technical and professional expertise who do not only concentrate on patient care, but also go further to demonstrate good leadership practices. In Zambia, the health sector’s mission is “to provide equity of access to costeffective quality health services as close to the family as possible”. Only competent leadership can drive such an agenda. This study, conducted in selected 1st level Lusaka hospitals aimed at establishing the existing common leadership practices and their influence on healthcare providers and service delivery.The study employed a cross-sectional qualitative research method design, to establish and examine the leadership practices through 10 health system managers and 32 healthcare providers. The data was obtained using in-depth interviews, focus group discussion, participant observation and document review. Data analysis was done by first transcribing audio-recorded interviews and grouping them into data sets (matrixes) where emerging themes were categorized manually. The information obtained assisted in making conclusions and interpretations by providing eminent explanations pointing to specific leadership styles and influence caused on healthcare providers and service delivery. The common leadership practices obtained in this study was the transformational leadership followed by transactional leadership while laissaze-fare was rare type of leadership. This conclusion was arrived at through the practices that were pointing to transformational and transactional leadership as preferred by the leaders and perceived or experienced by providers. These practices were explained as networking, interpersonal relationships, human/material resources management, monitoring and evaluation, dictatorial tendencies and overworking of employees. Furthermore, these practices were seen to have strong influence on healthcare providers through enhanced confidence, motivation for hard work and compromised quality of care. The resultant impact on service delivery was high quality performance as well as poor performance.Leadership styles affect employees’ commitment, motivation, satisfaction, extra effort and efficiency. This in turn has a bearing on performance and directly or indirectly influences patient care and its quality. Health system managers have a significant role in using leadership styles that promote good practice. It can be safely concluded that hospital performance and quality health care delivery services is a product of several factors. The analysis of leadership practices in this study shows two of the factors influencing hospital performance. The first factor is the effectiveness of leaders within the hospital and secondly the dedication, motivation, commitment and performance of employees that will improve health care services

Evaluation of oral hygiene services in selected public health facilities in Lusaka district of Zambia

Around the globe many people are suffering from oral pain and other problems of the mouth or teeth. This public health problem is growing rapidly in developing countries where oral health services are limited. This study was conducted in the public health centers and first level hospitals with dental units (DUs) in Lusaka district. Adequacy of dental equipment, instruments and materials required for scaling and polishing (S&P) and oral hygiene instructions (OHI) was evaluated. Challenges faced by the dental therapists (DTs) in the entire DUs were also evaluated. This was a mixed method study; quantitative data was collected using a structured questionnaire which contained a standard facility assessment check list. Qualitative data was collected by conducting in-depth interviews. The study results showed that the oral hygiene services offered by the selected DUs in Lusaka district were inadequate. A fully functional dental chair was available only in fifty percent of the DUs, only twenty percent of the facilities had fully functional ultrasonic scaling unit, none of the facilities had all the instruments for polishing. The DTs work under stressful conditions as sixty percent of the facilities were understaffed; the supply of dental instruments and materials was poor; delay in repairing faulty equipment; risk of exposure to air borne infections as most of the facilities have space and ventilation problems. Recommendations of this study point towards an urgent need to improve and coordinate the oral health care system

Alcohol Consumption in Lusaka Urban District, Zambia: A Population Based Survey, 2007

Alcohol use is an important preventable risk factor for several non-communicable diseases (NCDs) and injuries that is related to lifestyle choices. The objective of the study was to determine the prevalence of alcohol consumption and its correlates. A cross sectional study utilizing a WHO stepwise approach to surveillance of NCDs was conducted in Lusaka district, Zambia. Current alcohol consumption was defined as having consumed alcohol in the previous 30 days to the survey. Complex samples logistic regression was used to determine independent predictors. A total of 1928 individuals participated in the survey. A third of the participants were males and 53.2% were in the age group 25 to 34 years. Overall, 35.8% of the respondents had attained secondary level of education. The prevalence for current consumption of alcohol was 20.7% (37.9% of males and 12.2% of females). Sex was associated with alcohol consumption, with females being 68% (AOR = 0.32, 95%CI [0.20, 0.51]) less likely to consume alcohol compared to male respondents. Age, education, body mass index and sedentary were not independently associated with alcohol consumption. The high prevalence of alcohol use among Zambian adults indicates an urgent need for specific measures such as public awareness campaigns, policies, and regulations

HIV-positive demonstrate more salt sensitivity and nocturnal non-dipping blood pressure than HIV-negative individuals

Background: High dietary salt and a lack of reduced blood pressure (BP) at night (non-dipping) are risk factors for the development of hypertension which may result in end-organ damage and death. The effect of high dietary salt on BP in black people of sub-Saharan Africa living with HIV is not well established. The goal of this study was to explore the associations between salt sensitivity and nocturnal blood pressure dipping according to HIV and hypertension status in a cohort of adult Zambian population. Methods: We conducted an interventional study among 43 HIV-positive and 42 HIV-negative adults matched for age and sex. Study participants were instructed to consume a low (4 g) dietary salt intake for a week followed by high (9 g) dietary salt intake for a week. Salt resistance and salt sensitivity were defined by a mean arterial pressure difference of ≤5 mmHg and ≥ 8 mmHg, respectively, between the last day of low and high dietary salt intervention. Nocturnal dipping was defined as a 10–15% decrease in night-time blood pressure measured with an ambulatory blood pressure monitor. Results: The median age was 40 years for both the HIV-positive and the HIV-negative group with 1:1 male to female ratio. HIV positive individuals with hypertension exhibited a higher BP sensitivity to salt (95%) and nondipping BP (86%) prevalence compared with the HIV negative hypertensive (71 and 67%), HIV positive (10 and 24%) and HIV-negative normotensive (29 and 52%) groups, respectively (p < 0.05). Salt sensitivity was associated with non-dipping BP and hypertension in both the HIV-positive and HIV-negative groups even after adjustment in multivariate logistic regression (< 0.001). Conclusions: The results of the present study suggest that high dietary salt intake raises blood pressure and worsens nocturnal BP dipping to a greater extent in hypertensive than normotensive individuals and that hypertensive individuals have higher dietary salt intake than their normotensive counterparts. Regarding HIV status, BP of HIV-positive hypertensive patients may be more sensitive to salt intake and demonstrate more non-dipping pattern compared to HIV-negative hypertensive group. However, further studies with a larger sample size are required to validate this

Immediate pressor response to oral salt and its assessment in the clinic: a time series clinical trial

Background: High blood pressure (BP) is associated with high-salt consumption especially in sub-Saharan Africa. Although the pressor efect of salt is viewed as a chronic efect, some studies suggest that a salty meal may increase BP immediately in some individuals, and that this efect may cause endothelial dysfunction. Therefore, the aim of our research was to study the immediate pressor response to oral salt (IPROS) and its determinants, with the expectation that a simple methodology may be devised to diagnose it in the clinic or in low-resource environments. Methods: We conducted a time series trial at Livingstone Central Hospital. We present data in 127 normotensive participants who ingested 2g of sodium chloride; their BP was monitored for 120minutes in intervals of 10minutes. Sociodemographic and clinical data were collected. Descriptive and inferential statistics were used for analyses of data. Results: Median age was 30 years (interquartile range, 22–46 years) and 52% were female patients. An increase of ≥10mmHg in mean arterial pressure (MAP), considered a clinically signifcant IPROS, was present in 62% of participants. Systolic BP 30minutes after the salt load was a signifcant predictor of IPROS, avoiding the need to calculate MAP in the clinic setting. Conclusions: We confrm the presence of an IPROS in a high proportion (62%) of otherwise normotensive participants. The average time course for this response was 30minutes and its duration was sustained for the 120-minutes period of study in most of the participants. Prediction of IPROS by ∆SBP (change in systolic blood pressure) at 30minutes allows for easy assessment of possible responder status in the clinic. Our data indicate that the IPROS to oral saltloads in the range currently consumed by the Western world and African populations in single meals may increase the 24-hour BP load, which is a risk factor for hypertension and target organ damage. The relevance of our fndings indicates the need to include dietary sodium assessment in the diagnosis, prevention, and management of high BP
