Series Information
This survey is part of the Service Delivery Indicators (SDI) project, an initiative of the World Bank, the African Economic Research Consortium, and the African Development Bank. Started in 2012, SDI tracks performance and quality of service delivery in primary schools and frontline health facilities across Africa. Kenya was the first SDI country, following the pilot surveys in Tanzania and Senegal. In 2012-2013, surveys were conducted in Mozambique, Nigeria, Togo and Uganda; in 2014-2016, in Madagascar, Tanzania and Niger. The surveys are repeated every two years.

SDI initiative is a unique 10-year program and the World Bank is the implementing partner for the first five years.

The data distributed here has been harmonized to a common standard to facilitate comparisons across countries and time. The data also has been anonymized to preserve confidentiality of respondents. The harmonization and anonymization work is done by the World Bank's SDI team.

SDI surveys are documented in the Microdata Library as Service Delivery Indicators Health Surveys and Service Delivery Indicators Education Surveys.
Abstract
The SDI provides a set of metrics to benchmark the performance of schools and health facilities in Africa. The Indicators can be used to track progress within and across countries over time, and aim to enhance active monitoring of service delivery to increase public accountability and good governance. Ultimately, the goal of this effort is to help policymakers, citizens, service providers, donors, and other stakeholders enhance the quality of services and improve development outcomes. The perspective adopted by the Indicators is that of citizens accessing a service. The Indicators assemble objective and quantitative information from a survey of frontline service delivery units, using modules from the Public Expenditure Tracking Survey (PETS), Quantitative Service Delivery Survey (QSDS), and Staff Absence Survey (SAS). The SDI initiative is a partnership of the World Bank, the African Economic Research Consortium (AERC), and the African Development Bank.

Sampling

Sampling Procedure
The sampling frame that the Tanzania health SDI used was the 2012 list of health facilities obtained from the services of the MoHSW before the start of the field work. The original sample frame contained 7,472 health facilities with geographic identifier variables such as region, the division, the ward and even the street. This sample frame was merged with the list of wards from the most recent 2012 census to obtain the size of the population a specific facility is serving which will be later used as a weight for selecting facilities. The sample frame was then purged of 899 facilities which were not functional because they were either closed or under construction. A further 91 facilities were deleted from the frame because they were not eligible for the SDI i.e. regional hospitals, dental clinics, specialized clinics, etc. Two more facilities were suppressed because they served prison's population. This process left us with a final sample frame of 6,480 health facilities. With 995 (15 percent) of health facilities with missing information on ownership (i.e. public/private), the sample frame had an important challenge to offer. Because there was no way to determine the ownership status of those health facilities before going to the field, the facilities were left in the frame but categorized as unknown for ownership. During the data collection the head of facility was asked about their facility's ownership status and the data collected. This new information will be used for post-stratification adjustment. Although the SDI is usually representative at the national and urban and rural areas, in Tanzania it was requested that the survey be also representative of the traditional strata in household surveys which are (1) Dar es Salaam, (2) other urban areas, and (3) rural areas.

Sampling was done using a two-stage sampling method. First, in each stratum districts are drawn with probability proportional to size (PPS). Then the allocated number of health facilities are drawn using PPS again within the set of selected districts in the stratum. Once at a selected health facility, the enumerator selected health workers from the staff roster filled out by the head of facility. The facilities were chosen using PPS, where size is the population served by the facility as provided by the 2012 census database. As for the selection of the cluster, the use of PPS implies that each individual within a stratum has an equal probability for her facility to be selected. Finally within each health facility, up to 10 health workers are selected. There are 2 different procedures for measuring absenteeism or assessing knowledge. For absence, 10 health workers are selected in the staff roster using a random numbers table and the whereabouts of those health workers is ascertained in a return surprise visit. For the assessment, however, only health workers who actually see patients i.e. provide a diagnostic and treatment are eligible. These procedures imply that facilities across strata as well as health workers across strata and within facility (for assessment) do not all have the same probability of selection. It is therefore warranted to compute weights for reporting the survey results.
Deviations from the Sample Design
None.
Weighting
To be representative of the population of interest, sample estimates from the 2014 Tanzania SDI have to be properly weighted using a sampling weight, or expansion factor. Note that different weights will need to be applied depending on the relevant level for the variable which can be the facility or the staff. The basic weight for each entity is equal to the inverse of its probability of selection which is computed by multiplying the probabilities of selection at each sampling stage. All the weights have been computed and included in the dataset.

Questionnaires

Questionnaires
Four modules were used, with multiple sections under the following themes:
• Module 1: Facility information
• Module 2: Staff roster
• Module 3: Patient case simulations (to measure provider knowledge)
• Module 4: Facility expenditure, resources and governance (not included in public release files)

Data Processing

Data Editing
Data entry and editing was done with CSPro.
Other Processing
Data sets are harmonized to a common questionnaire and subsequently anonymized. For more information on both procedures, please refer to the technical documents: Note to Users (readme_sdi_health.pdf/lisezmoi.pdf), Tanzania Health - Harmonization Information (tanzania_health_20150824.xlsx) as well as the SDC report provided as external resources.
