Short-term dynamics and long-term relationship between natural gas consumption and economic growth in Nigeria: an ARDL approach with breaks.

This paper investigates the short-term dynamics as well as the long-term relationship between natural gas consumption and economic growth in Nigeria, taking breaks into account. The techniques employed include Shahbaz-Omay-Roubaud unit root test with sharp and smooth breaks and autoregressive distributed lag (ARDL) model with breaks. The results revealed that natural gas consumption is positively related to growth both in the short-term and long-term but only significant in the latter. However, there is evidence of bidirectional causality in the long-term and unidirectional causality in the short-term, from growth to natural gas consumption. The implication of the findings is that natural gas is a contributing factor to the growth of the Nigerian economy, and any energy policy aimed at increasing the consumption of natural gas could lead to the increase in economic growth and that Nigerian authorities could adopt energy conservation policies in the short-term so as to take the issue of global warming into consideration. Therefore, the paper recommends stepping up efforts to increase natural gas consumption by building more gas storage facilities, pipeline installations, exploring alternative energy sources, raising awareness/enlightenment about the uses of natural gas, suitability in its use, economic and environmental benefits of its use, ensuring its affordable availability, and beeping up security against pipelines vandalization. Moreover, in the short-term, the country could enact energy conservation policies to combat global warming.

Cost of Illness of Diabetic Foot Ulcer in a Resource Limited Setting: A Study from Northwestern Nigeria.

INTRODUCTION: Diabetic foot ulcer is a major complication of diabetes with a high economic cost of managing. Data from resource limited setting will bring to light how patients in these localities suffer financially in addition to poverty and lack of health insurance. This study estimated cost of illness among patients with diabetic foot ulcer in northwestern Nigeria. METHODS: It was a hospital based cross-sectional study. Questionnaire was used to take the bio data and medical history. Direct medical, direct non-medical and indirect cost were estimated. RESULT: Majority of the patients were males with the mean age of 59.3 ± 15.1 yrs. About 60% of the patients earn less than $100 monthly. The total cost of illness of diabetic foot ulcer was estimated at $140,735.56 (median = $1381.55[IQR 1002.42-]). Direct cost of illness was $107,797.06 (median = $1023.27[IQR 773.93-1568]), while the indirect cost was $32,938.49 (median = $209.90[IQR 128.74-357.08]). Out of pocket payment accounted for 90% of the payment. CONCLUSION: The cost of diabetic foot ulcer is very exorbitant and the patients affected are mostly poor, unemployed and the breadwinners of their families.

Assessment of level of satisfaction of national health insurance scheme enrolees with services of an accredited health facility in Northern Nigerian

Introduction: Consumer satisfaction is one of the driving goals of goods and service production. Patient satisfaction surveys, as a means of periodic evaluation of the quality of services offered by the National Health Insurance Scheme (NHIS) accredited facilities, is necessary to ensure that the goals of the scheme are achieved and sustained. Materials and Methods: This was a cross-sectional study of 202 respondents randomly selected from NHIS enrolees attending the Staff Clinic of Aminu Kano Teaching Hospital. It assessed respondents' perceived waiting time, level of satisfaction at the clinic's service units, and overall clinic satisfaction using a modified general practice assessment questionnaire. Results: The mean age of respondents was 36.4 ± 8.1 with a near equal sex ratio. They were predominantly civil servants (79.2%) with tertiary education (75.7%). Most respondents (70.3%) felt waiting time was too long; with 79.7% of those, feeling they spend at least 30 min after arrival at the registration unit to see their doctor. A majority of respondents: 90.1%, 86.8%, 79%, 76.8%, 75.9%, 77.5%, and 80.6% were satisfied with the consultation time, doctors' consultation, medical records, pharmacy, laboratory, accounts, and nursing services, respectively. However, 65.8% were satisfied with the overall clinic services. The perceived sufficiency of the consultation time was associated with overall satisfaction (χ2 = 6.199, P = 0.013). Conclusion: Although 65.8% of respondents were satisfied with the clinic services, the perceived clinic waiting time was dissatisfactory; therefore, further studies on the determinants of overall satisfaction may be required if improvement in the proportion of satisfied service consumers is desired by the clinic managers
