BACKGROUND AND PURPOSE OF RESEARCH: Nigeria’s National Health Insurance Scheme (NHIS) was setup to secure universal access to affordable quality care. However, after 11yrs, and despite launching different programs, NHIS coverage is still less than 3% nationally, and out-of-pocket payments (OOP) remain the major health financing mechanism. The reasons for the low level of enrollment in NHIS are not well understood. Quality of care may be a factor in enrolment. This study compares technical and perceived quality of care between NHIS enrollees and the uninsured, using diabetes as a tracer condition. It also compares OOP and generic prescription patterns by health insurance enrollment status. METHODS: We conducted a cross sectional clinic-based intercept study. Subjects were adult diabetes patients recruited from 10 NHIS accredited hospitals in Abuja, Nigeria. Data collection included survey and chart review, covering technical aspects of quality – performance of eye and feet exam and HbA1c request; perception of quality, generic medication prescribing pattern and OOP. We performed logistic regression analysis to evaluate the effect of NHIS enrollment status on the technical quality of care, perceived quality of care, generic prescribing and OOP. RESULTS: Out of 455 participants, 149 (33%) were NHIS enrollees, 10 (2%) were enrolled in private health insurance and 296 (65%) had no insurance. After adjusting for correlated data and controlling for facility, BMI, chronic disease score, age, sex, and education, patients under NHIS coverage were 0.85 times less likely to have eye exam (Cl=0.4–1.8), 0.98 times less likely to have feet exam (Cl= 0.4–2.2), and 0.98 times less likely to have A1c test requested (Cl= 0.7–1.3), compared to those without insurance. These findings were not statistically significant at alpha=0.05. On the other hand, compared to the uninsured, NHIS covered patients perceived care to be worse even though they spent significantly less, 56% (Cl=45%–69%) in OOP in public hospitals. DISCUSSION/CONCLUSION: Perception of care quality under the NHIS could be a contributory factor to the reluctance of prospective enrollees. To advance towards the goal of universal health coverage, NHIS must strengthen policy to overcome identified barriers such as medication stock outs and wait times at the facility level.

Non-monetary deprivation indicators are now widely used for studying and measuring poverty in Europe. However, despite their prevalence, the empirical performance of existing deprivation scales has rarely been examined. This thesis i) identifies possible conceptual problems of existing deprivation scales such as indexing, missing dimensions and threshold; ii) empirically assesses the extent of possible error in measurement related to these conceptual problems; and iii) offer an alternative way for constructing deprivation measures to mitigate the identified conceptual problems. The thesis consists of four stand-alone papers, accompanied by an overarching introduction and conclusion. The first three papers provide empirical evidence on the empirical consequences of the missing dimensions and threshold problems for the measurement and analysis of poverty, while the fourth paper exemplifies a concept-led multidimensional design that can reduce the error introduced by these conceptual problems. The analysis is generally held for 25 EU countries using European Survey of Income and Living Conditions (EU-SILC); only in the second paper, the analysis is done for the UK using British Household Panel Survey (BHPS).
