Project objectives
• Expand the evidence base in support of effective use of mid-level health workers within an enabling environment through the generation of new evidence and a critical analysis of existing evidence;
• Increase recognition and effective use of mid-level health workers among national, regional, and global policymakers to address the human resources crisis in district health systems based on project evidence;
• Advocate for an enabling environment that optimises performance of mid-level providers in order to strengthen health systems; and
• In partnership with African institutions, deepen local capacity to research and analyse human resource and health systems problems, develop innovative solutions, influence policymakers at local and global levels, and sustainably implement new strategies; and build the capacity of northern institutions to successfully engage in and support partnerships of this kind.
Research Advocacy
Review of previous DCE work
• Previous studies mostly with students• Prior experience influences choice – important to focus
on established health workers as their choices may be very different
• All except one previous study conducted with doctors and nurses – yet health systems staffed by mid-level providers
• Most studies - single country• Previous DCE work tells us little about the factors that
are important in motivating and retaining this majority component of human resources for health.
Distinctive features of this study
• Large sample (2,072)• Across three countries (Malawi, Tanzania,
Mozambique)• Health workers in the health system• Includes mid-level cadres• Variables – human resource management and
continuing professional development

Table 2. Descriptive statistics for the demographic characteristics and cadre breakdown of participants in Malawi, Tanzania, and Mozambique
DCE - Basic Approach• Present different composite jobs• Respondents evaluate jobs relative to each other
– Rate, rank, discrete choices
• Analyse choices– Infer underlying value system from the choices made about jobs
• Can provide estimation of:– Relative importance of different attributes – Willingness of respondents to trade-off between attributes– Relative benefit/utility scores of different combinations– Values of different subgroups
Selection of Attributes
• Key attributes which define job • Limited by experimental design consideration• Attributes and levels should be actionable
• Based on:– Literature review– Expert opinion– Key informant interviews– Focus group discussions– Surveys– Policy relevance– Findings from previous studies (MaxHR)
Job Attributes
Geographic Location• This attribute specifies whether your place of work is in an urban or rural
area. Net Monthly Pay (including regular allowances)• Base represents the base salary for a health worker at an “average” grade
in the civil service pay scale, while higher levels are multiples (1.5 times and 2 times) of this average base level. Note that the base salary does not necessarily reflect your current actual salary.
Government-provided Housing• None means there is no housing provided by the government as part of the
conditions of employment. • Basic housing means the government provides housing for the health
worker, but that it is rudimentary, having no electricity or running water, and with at best an outside toilet.
• Superior housing means the government provides housing of higher quality, including the presence of electricity and running water, including an inside flush toilet.
Job Attributes (cont.)
Availability of Equipment and Drugs
• Inadequate is the standard of equipment and availability of drugs that you might expect in a poorly equipped public facility in the given location.
• Improved is the level of supplies that would result from a doubling of the budget currently spent on equipment and drugs.
Access to Continuing Professional Development
• This attribute measures the availability of continuing professional development, in terms of access to further education and upgrading. Limited access means there are very few opportunities, with no clear guidelines on who can avail of them.
• Improved access means there are sufficient opportunities available, with clear policies on the criteria needed to qualify for places.
Job Attributes (cont.)
Human Resources Management Systems
• Poor describes a management system with either no mechanisms or poorly administered mechanisms for staff support, supervision and appraisal.
• Functioning describes a system where there are transparent, accountable and consistent systems for staff support, supervision and appraisal.
Design
• Fractional factorial design• 15 choice sets• 6 attributes
– 4 with two levels– 2 with three levels
• Job 1 held constant

Section L: Discrete Choice Experiment
If your circumstances permitted it, which of the two jobs described would you choose?
Tick one: Job 1 Job 2
Analysis
• Initially data was analyzed using the conditional logit model (CLM).
• The CLM allows observing how the characteristics of the alternatives affect individuals’ likelihood of choosing them; it has been extensively used in the discrete choice model literature (Louviere & Lancsar, 2009; Lanscar & Louviere, 2008; Guttman et al., 2009).
• The baseline model tested assumed linear effects across all attribute parameters.
Analysis (2)
• Additionally, to test for non-linear relationship between an attribute and utility, three dummy variables were included to represent each level of the three-level attributes (housing and net monthly pay).
• The design above was then merged with the dataset containing the choices made by respondents, and the other socio-economic and job related information.
• control variables representing socio-economic and demographic characteristics are also included in the final dataset that was analyzed: zone, gender, education, age and edu_level.
Dataset (Malawi as example)
• The original dataset contained 631 respondents and the DCE answers were identified by dce_1, dce_2,…, dce_15, indicating the respondents choices for each of the 15 choice sets presented to them.
• The final dataset has 9,465 choices made (15 X 631). 74.84% of the choices were for alternative one (job1, constant alternative) and 20.1% for alternative 2 (job 2).
• Approximately 5% of choice sets were not answered and these were dropped from the final dataset.
• The final dataset therefore contained 8,986 choices made.
Results
• All coefficients are statistically significant indicating all attributes have influence on the choice between job1 or job 2.
• They have positive values, indicating that increases in the level of the attributes increases the utility of choice. These are in accordance with the a priori expectations (external validity).

Table 5: Conditional logit model results (Tanzania) – baseline model
Attributes with highest part-worth utilities were professional development (pdev=1,199) and human resources management (hrm =1,181).
An improvement in any of these two attributes impacts more on the utility than any other attribute in the design.

Table 6: Conditional logit model results (Mozambique)– baseline model
Attributes with greater utility were professional development (pdev=1,534) and human resources management (hrm =1,332).
Testing for non-linear effects
• Two of the six attributes had 3 levels, net monthly pay and housing,
• To test for non-linear effects– including in the model the dummy variables for housing and pay attributes (Test
for non-linear effects allows observing whether the effect on utility from an increasing in the salary level (or housing) from the basic salary to 1,5 the basic (or from no housing to basic housing) is different from an increase from 1,5 the basic to 2 times the basic (or from basic housing to superior housing).)
• They were included separately and the goodness of fit was compared with the baseline model of linear effect of each three levels attribute
• a Wald test was applied to check whether or not the dummy variables included were different from zero. If so, it implies that there are non-linear effects on the three levels attributes, i.e., the impact on utility is different when moving from pay1 to pay2 compared to a change from pay2 to pay3 (or houseno to houseba compared to houseba to housesu).
Results
• Expanded model did not provide a better fit for the data.
• Non-linearity detected for pay only in Malawi

In Summary• Consistent results across three countries• Strongest predictors of job choice - access to CPD and HRM• Strong preferences for functioning HRM and available professional
development that operates with clear policies• Consistent with other studies – pay is important but perhaps not as
fundamental as suggested by previous studies• Further analysis – differences between cadres, demographic
profiles of health worker.
Additional data
Demographics
• Job title• Employment status• Employer type• Employer location• Gender• Age• Education• Professional affiliations• Length of time with employer• Work pattern• Payment patterns
Provider survey
• Job satisfaction• Burnout levels• Work environment• Commitment• Intention to leave• Organisational justice• Supervision• Career progression
opportunities
Limitations of DCE• Stated vs actual preferences
– Artificial / hypothetical constructs may not predict real choices
• Limited number of attributes and levels– Significant design constraints
• Have the most influential attributes been selected?– Different results with different attributes
In this study qualitative and quantitative data collected using a variety of instruments are consistent with DCE findings.
