The effects of improved sanitation on diarrheal prevalence, incidence, and duration in children under five in the SNNPR State, Ethiopia: study protocol for a randomized controlled trial.

BACKGROUND: Diarrhea is one of the leading causes of death, killing 1.3 million in 2013 across the globe, of whom, 0.59 million were children under 5 years of age. Globally, about 1 billion people practice open defecation, and an estimated 2.4 billion people were living without improved sanitation facilities in 2015. Much of the previous research investigating the effect of improved sanitation has been based on observational studies. Recent studies have executed a cluster-randomized controlled trial to investigate the effect of improved sanitation. However, none of these recent studies achieved a sufficient level of latrine coverage. Without universal or at least a sufficient level of latrine coverage, a determination of the effect of improved latrines on the prevention of diarrheal disease is difficult. This cluster-randomized trial aims to explore the net effect of improved latrines on diarrheal prevalence and incidence in children under five and to investigate the effect on the diarrheal duration. METHOD/DESIGN: A phase-in and factorial design will be used for the study. The intervention for improving latrines will be implemented in an intervention arm during the first phase, and the comparable intervention will be performed in the control arm during the second phase. During the second phase, a water pipe will be connected to the gotts (villages) in the intervention arm. After the second phase is completed, the control group will undergo the intervention of receiving a water pipe connection. For diarrheal prevalence, five rounds of surveying will be conducted at the household level. The first four rounds will be carried out in the first phase to explore the effect of improved latrines, and the last one, in the second phase to examine the combined effects of improved water and sanitation. For documentation of diarrheal incidence and duration, the mother or caregiver will record the diarrheal episodes of her youngest child on the "Sanitation Calendar" every day. Of 212 gotts in the project area, 48 gotts were selected for the trial, and 1200 households with a child under 5 will be registered for the intervention or control arm. Informed consent from 1200 households will be obtained from the mother or caregiver in written form. DISCUSSION: To our knowledge, this is the second study to assess the effects of improved latrines on child diarrheal reduction through the application of Community-Led Total Sanitation.

Exploring the influence of trust relationships on motivation in the health sector: a systematic review.

BACKGROUND: Dedicated and motivated health workers (HWs) play a major role in delivering efficient and effective health services that improve patients' experience of health care. Growing interest in HW motivation has led to a global focus on pay for performance strategies, but less attention has been paid to nurturing intrinsic motivation. Workplace trust relationships involve fair treatment and respectful interactions between individuals. Such relationships enable cooperation among HWs and their colleagues, supervisors, managers and patients and may act as a source of intrinsic motivation. This paper presents findings from a qualitative systematic review of empirical studies providing evidence on HW motivation, to consider what these studies suggest about the possible influence of workplace trust relationships over motivation. METHODS: Five electronic databases were searched for articles reporting research findings about HW motivation for various cadres published in the 10-year period 2003 to 2013 and with available full free text in the English language. Data extraction involved consideration of the links between trust relationships and motivation, by identifying how studies directly or indirectly mention and discuss relevant factors. RESULTS: Twenty-three articles from low- and middle-income countries and eight from high-income countries that met predetermined quality and inclusion criteria were appraised and subjected to thematic synthesis. Workplace trust relationships with colleagues, supervisors and managers, employing organisation and patients directly and indirectly influence HW motivation. Motivational factors identified as linked to trust include respect; recognition, appreciation and rewards; supervision; teamwork; management support; autonomy; communication, feedback and openness; and staff shortages and resource inadequacy. CONCLUSION: To the authors' knowledge, this is the first systematic review on trust and motivation in the health sector. Evidence indicates that workplace trust relationships encourage social interactions and cooperation among HWs, have impact on the intrinsic motivation of HWs and have consequences for retention, performance and quality of care. Human resource management and organisational practices are critical in sustaining workplace trust and HW motivation. Research and assessment of the levels of motivation and factors that encourage workplace trust relationships should include how trust and motivation interact and operate for retention, performance and quality of care
