An assessment of equity in the distribution of non-financial health care inputs across public primary health care facilities in Tanzania

Abstract

BackgroundThere is limited evidence on how health care inputs are distributed from the sub-national level down to health facilities and their potential influence on promoting health equity. To address this gap, this paper assesses equity in the distribution of health care inputs across public primary health facilities at the district level in Tanzania.MethodsThis is a quantitative assessment of equity in the distribution of health care inputs (staff, drugs, medical supplies and equipment) from district to facility level. The study was carried out in three districts (Kinondoni, Singida Rural and Manyoni district) in Tanzania. These districts were selected because they were implementing primary care reforms. We administered 729 exit surveys with patients seeking out-patient care; and health facility surveys at 69 facilities in early 2014. A total of seventeen indices of input availability were constructed with the collected data. The distribution of inputs was considered in relation to (i) the wealth of patients accessing the facilities, which was taken as a proxy for the wealth of the population in the catchment area; and (ii) facility distance from the district headquarters. We assessed equity in the distribution of inputs through the use of equity ratios, concentration indices and curves.ResultsWe found a significant pro-rich distribution of clinical staff and nurses per 1000 population. Facilities with the poorest patients (most remote facilities) have fewer staff per 1000 population than those with the least poor patients (least remote facilities): 0.6 staff per 1000 among the poorest, compared to 0.9 among the least poor; 0.7 staff per 1000 among the most remote facilities compared to 0.9 among the least remote. The negative concentration index for support staff suggests a pro-poor distribution of this cadre but the 45 degree dominated the concentration curve. The distribution of vaccines, antibiotics, anti-diarrhoeal, anti-malarials and medical supplies was approximately proportional (non dominance), whereas the distribution of oxytocics, anti-retroviral therapy (ART) and anti-hypertensive drugs was pro-rich, with the 45 degree line dominating the concentration curve for ART.ConclusionThis study has shown there are inequities in the distribution of health care inputs across public primary care facilities. This highlights the need to ensure a better coordinated and equitable distribution of inputs through regular monitoring of the availability of health care inputs and strengthening of reporting systems.Electronic supplementary materialThe online version of this article (doi:10.1186/s12939-017-0620-0) contains supplementary material, which is available to authorized users.

Prenatal HIV Test Uptake and Its Associated Factors for Prevention of Mother to Child Transmission of HIV in East Africa

“…It could be argued that lower HIV testing service use amongst women living in rural areas, could be related to unequal access to society's resources that include education, employment and health care services [60][61][62][63][64] and existing systematic socioeconomic disparities between urban-rural dwellers. Additionally, increased stigma and discrimination in rural communities [65] and shortages of qualified health professionals and supplies in the rural health facilities [60,66] may lead to lower utilization of HIV testing services amongst pregnant women from rural areas. This suggests that strategies targeting rural areas must be strengthened to reduce barriers to prenatal HIV testing for PMTCT of HIV.…”

“…Meaningfully, more than 90% of women in this study reported that their pregnancy was planned and of those, approximately 75% had been tested for HIV. Furthermore, educated women are more likely to make decisions to seek health care [69] and reside in urban areas where there is easier access to health facilities that provide quality PMTCT of HIV services [63,66].…”

Development and upgrading of public primary healthcare facilities with essential surgical services infrastructure: a strategy towards achieving universal health coverage in Tanzania

“…Health system infrastructure ranges from the physical facilities, information systems to medical equipment and also involves construction of new infrastructure as a strategy to achieving UHC [4]. To provide quality health services required for universal health coverage, health facilities should be structured to meet health care needs and equipped with utilities such as electricity, water and skilled health workforce and also to construct or renovate primary health facilities that are able to offer quality services [5,6]. Furthermore, improvement in geographical access of health services provision through strategic infrastructure development strengthens the referral system, increase service utilization and, in so doing, improve health outcome indicators at individual and community level.…”

Bank accounts for public primary health care facilities: Reflections on implementation from three districts in Tanzania

“…Adequate and equitable financing remains a challenge for many low income country health systems', constraining access to services of sufficient quality [1][2][3][4][5]. As a result, some countries have embarked on a series of reforms to raise additional revenue [1][2][3][4][5][6], change how services are paid for, as well as how funds flow through the system and are managed. Decentralisation of financial management from central or local government level to facility level is one among many reforms that are gaining popularity in a number of African countries and has been found to increase the availability and accessibility of funds at the service delivery level [7,8].…”
