Does payment for performance increase performance inequalities across health providers? A case study of Tanzania.

The impact of payment-for-performance (P4P) schemes in the health sector has been documented, but there has been little attention to the distributional effects of P4P across health facilities. We examined the distribution of P4P payouts over time and assessed whether increased service coverage due to P4P differed across facilities in Tanzania. We used two service outcomes that improved due to P4P [facility-based deliveries and provision of antimalarials during antenatal care (ANC)], to also assess whether incentive design matters for performance inequalities. We used data from 150 facilities from intervention and comparison areas in January 2012 and 13 months later. Our primary data were gathered through facility survey and household survey, while data on performance payouts were obtained from the programme administrator. Descriptive inequality measures were used to examine the distribution of payouts across facility subgroups. Difference-in-differences regression analyses were used to identify P4P differential effects on the two service coverage outcomes across facility subgroups. We found that performance payouts were initially higher among higher-level facilities (hospitals and health centres) compared with dispensaries, among facilities with more medical commodities and among facilities serving wealthier populations, but these inequalities declined over time. P4P had greater effects on coverage of institutional deliveries among facilities with low baseline performance, serving middle wealth populations and located in rural areas. P4P effects on antimalarials provision during ANC was similar across facilities. Performance inequalities were influenced by the design of incentives and a range of facility characteristics; however, the nature of the service being targeted is also likely to have affected provider response. Further research is needed to examine in more detail the effects of incentive design on outcomes and researchers should be encouraged to report on design aspects in their evaluations of P4P and systematically monitor and report subgroup effects across providers.

Who benefits from increased service utilisation? Examining the distributional effects of payment for performance in Tanzania.

BACKGROUND: Payment for performance (P4P) strategies, which provide financial incentives to health workers and/or facilities for reaching pre-defined performance targets, can improve healthcare utilisation and quality. P4P may also reduce inequalities in healthcare use and access by enhancing universal access to care, for example, through reducing the financial barriers to accessing care. However, P4P may also enhance inequalities in healthcare if providers cherry-pick the easier-to-reach patients to meet their performance targets. In this study, we examine the heterogeneity of P4P effects on service utilisation across population subgroups and its implications for inequalities in Tanzania. METHODS: We used household data from an evaluation of a P4P programme in Tanzania. We surveyed about 3000 households with women who delivered in the last 12 months prior to the interview from seven intervention and four comparison districts in January 2012 and a similar number of households in 13 months later. The household data were used to generate the population subgroups and to measure the incentivised service utilisation outcomes. We focused on two outcomes that improved significantly under the P4P, i.e. institutional delivery rate and the uptake of antimalarials for pregnant women. We used a difference-in-differences linear regression model to estimate the effect of P4P on utilisation outcomes across the different population subgroups. RESULTS: P4P led to a significant increase in the rate of institutional deliveries among women in poorest and in middle wealth status households, but not among women in least poor households. However, the differential effect was marginally greater among women in the middle wealth households compared to women in the least poor households (p = 0.094). The effect of P4P on institutional deliveries was also significantly higher among women in rural districts compared to women in urban districts (p = 0.028 for differential effect), and among uninsured women than insured women (p = 0.001 for differential effect). The effect of P4P on the uptake of antimalarials was equally distributed across population subgroups. CONCLUSION: P4P can enhance equitable healthcare access and use especially when the demand-side barriers to access care such as user fees associated with drug purchase due to stock-outs have been reduced.

Estimating the costs for the treatment of abortion complications in two public referral hospitals: a cross-sectional study in Ouagadougou, Burkina Faso.

BACKGROUND: Treatment costs of induced abortion complications can consume a substantial amount of hospital resources. This use of hospitals scarce resources to treat induced abortion complications may affect hospitals' capacities to deliver other health care services. In spite of the importance of studying the burden of the treatment of induced abortion complications, few studies have been conducted to document the costs of treating abortion complications in Burkina Faso. Our objective was to estimate the costs of six abortion complications including incomplete abortion, hemorrhage, shock, infection/sepsis, cervix or vagina laceration, and uterus perforation treated in two public referral hospital facilities in Ouagadougou and the cost saving of providing safe abortion care services. METHODS: The distribution of abortion-related complications was assessed through a review of postabortion care-registers combined with interviews with key informants in maternity wards and in hospital facilities. Two structured questionnaires were used for data collection following the perspective of the hospital. The first questionnaire collected information on the units and the unit costs of drugs and medical supplies used in the treatment of each complication. The second questionnaire gathered information on salaries and overhead expenses. All data were entered in a spreadsheet designed for studying abortion, and analyses were performed on Excel 2007. RESULTS: Across six types of abortion complications, the mean cost per patient was USD45.86. The total cost to these two public referral hospital facilities for treating the complications of abortion was USD22,472.53 in 2010 equivalent to USD24,466.21 in 2015. Provision of safe abortion care services to women who suffered from complications of unsafe induced abortion and who received care in these public hospitals would only have cost USD2,694, giving potential savings of more than USD19,778.53 in that year. CONCLUSIONS: The treatment of the complications of abortion consumes a significant proportion (up to USD22,472.53) of the two public hospitals resources in Burkina Faso. Safe abortion care services may represent a cost beneficial alternative, as it may have saved USD19,778.53 in 2010.

Costs and consequences of abortions to women and their households: a cross-sectional study in Ouagadougou, Burkina Faso.

Little is known about the costs and consequences of abortions to women and their households. Our aim was to study both costs and consequences of induced and spontaneous abortions and complications. We carried out a cross-sectional study between February and September 2012 in Ouagadougou, the capital city of Burkina Faso. Quantitative data of 305 women whose pregnancy ended with either an induced or a spontaneous abortion were prospectively collected on sociodemographic, asset ownership, medical and health expenditures including pre-referral costs following the patient's perspective. Descriptive analysis and regression analysis of costs were performed. We found that women with induced abortion were often single or never married, younger, more educated and had earlier pregnancies than women with spontaneous abortion. They also tended to be more often under parents' guardianship compared with women with spontaneous abortion. Women with induced abortion paid much more money to obtain abortion and treatment of the resulting complications compared with women with spontaneous abortion: US$89 (44 252 CFA ie franc of the African Financial Community) vs US$56 (27 668 CFA). The results also suggested that payments associated with induced abortion were catastrophic as they consumed 15% of the gross domestic product per capita. Additionally, 11-16% of total households appeared to have resorted to coping strategies in order to face costs. Both induced and spontaneous abortions may incur high expenses with short-term economic repercussions on households' poverty. Actions are needed in order to reduce the financial burden of abortion costs and promote an effective use of contraceptives.

Using incentives to attract nurses to remote areas of Tanzania: a contingent valuation study.

This article analyses (1) how financial incentives (salary top-ups) and non-financial incentives (housing and education) affect nurses' willingness to work in remote areas of Tanzania and (2) how the magnitude of the incentives needed to attract health workers varies with the nurses' geographic origin and their intrinsic motivation. A contingent valuation method was used to elicit the location preferences of 362 nursing students. Without any interventions, 19% of the nurses were willing to work in remote places. With the provision of free housing, this share increased by 15 percentage points. Better education opportunities increased the share by 28 percentage points from the baseline. For a salary top-up to have the same effect as provision of free housing, the top-up needs to be between 80 and 100% of the base salary. Similarly, for salary top-ups to have the same effect as provision of better education opportunities, the top-up should be between 120 and 140%. Our study confirms results from previous research, that those with a strong intrinsic motivation to provide health care are more motivated to work in a remote location. A more surprising finding is that students of older age are more prepared to take a job in remote areas. Several studies have found that individuals who grew up in a remote area are more willing to work in such locations. A novel finding of our analysis is that only nursing students with a 'very' remote origin (i.e. those who grew up farther from a district centre than the suggested remote working place) express a higher willingness to take the remote job. Although we do control for nursing school effects, our results could be biased due to omitted variables capturing individual characteristics.

Overworked? On the relationship between workload and health worker performance.

The shortage of health workers in many low-income countries poses a threat to the quality of health services. When the number of patients per health worker grows sufficiently high, there will be insufficient time to diagnose and treat all patients adequately. This paper tests the hypothesis that high caseload reduces the level of effort per patient in the diagnostic process. We observed 159 clinicians in 2095 outpatient consultations at 126 health facilities in rural Tanzania. Surprisingly, we find no association between caseload and the level of effort per patient. Clinicians appear to have ample amounts of idle time. We conclude that health workers are not overworked and that scaling up the number of health workers is unlikely to raise the quality of health services. Training has a positive effect on quality but is not in itself sufficient to raise quality to adequate levels.
