Cost-effectiveness of dolutegravir vs. efavirenz-based combined antiretroviral therapies in HIV-infected treatment-naive patients in a Nigerian treatment centre.

Background: Dolutegravir (DTG) based antiretroviral therapy (ART) has largely replaced Efavirenz (EFV) based therapy as the preferred first-line regimen in the treatment of adults with HIV. This study was carried out to evaluate the comparative cost-effectiveness of DTG and EFV-based ART in HIV-infected treatment-naïve patients in a treatment centre in Nigeria. Methods: This was a retrospective case-control study of patients initiated on DTG vs. EFV-based regimens from January 2018 to December 2019 at the APIN/HAVARD clinic of Nigeria's Jos University Teaching Hospital. The current viral load result was used to determine treatment effectiveness using a benchmark of ≤200 copies/mL. Sensitivity analysis was carried out to ensure the robustness of the benchmark. The total cost of treatment was obtained by summing up the relevant cost components. Appropriate descriptive and inferential statistics were employed in data analysis using Statistical Product and Services Solutions (SPSS) V.25. The incremental cost-effectiveness ratio of DTG compared to EFV was presented as cost/effectiveness. Results: Treatment was effective in 42(51.9%) and 58(71.6%) patients initiated on DTG and EFV-based regimen, respectively. The incremental cost-effective ratio (ICER) of patients on DTG compared to those on EFV was $10.5076 per effectiveness, which was less than 1% of the Nigerian 2019 per capita Gross Domestic Product. Sensitivity analysis showed the robustness of the result. Conclusion: Efavirenz based regimen had higher treatment effectiveness than DTG-based regimen in treatment-naive patients after initiating treatment in a short term. Compared to EFV, DTG-based regimen is cost-effective in the management of treatment naïve HIV patients.

A qualitative study of patients' and carers' perspectives on factors influencing access to hypertension care and compliance with treatment in Nigeria.

OBJECTIVE: We explored patients' and carers' perspectives on factors influencing access to hypertension care and compliance with treatment. METHODS: This was a qualitative study using in-depth interviews with hypertensive patients and/or family carers receiving care at a government-owned hospital in north-central Nigeria. Eligible participants were patients who had hypertension, receiving care in the study setting, were aged 55 years and over and had given their written/thumbprint consent to participate in the study. An interview topic guide was developed from the literature and through pretesting. All the interviews were held face-to-face by a member of the research team. This study was conducted between December 2019 and February 2020. NVivo version 12 was used to analyse the data. RESULTS: A total of 25 patients and 13 family carers participated in this study. To understand the barriers to compliance with hypertension self-management practices, three themes were explored, namely: personal factors, family/societal factors and clinic/organization factors. Support was the key enabling factor for self-management practices, which were categorized to emerge from three sources namely: family members, community and government. Participants reported that they do not receive lifestyle management advice from healthcare professionals, and do not know the importance of eating low-salt diets/engaging in physical activities. CONCLUSION: Our findings show that study participants had little or no awareness of hypertension self-management practices. Providing financial support, free educational seminars, free blood pressure checks, and free medical care for the elderly could improve hypertension self-management practices among patients living with hypertension.

Health-related quality of life associated with different cervical cancer therapies received by patients in two Nigerian tertiary hospitals.

Background: There are important consequences from cervical cancer (CC) disease and its treatment among survivors, especially the impact on quality of life (QoL). Objective: To evaluate the health-related QoL associated with different CC therapies received by patients in two Nigerian tertiary hospitals. Methods: This study employed a prospective longitudinal design. It was conducted at Usmanu Danfodiyo University Teaching Hospital, Sokoto and Ahmadu Bello University Teaching Hospital Zaria, North-Western Nigeria. Data of all the 157 eligible CC patients were collected at baseline and after therapy. Data analysis was done with appropriate descriptive and inferential statistics using SPSS V. 20 for windows. P<0.05 was considered statistically significant. Results: Chemotherapy (CT) was the major therapy option received by 78(49.7%) of the patients. Patients who received chemoradiation therapy (CRT) and adjuvant chemotherapy (CTS) had the highest increase in mean overall health-related QoL of 0.138 (t=8.456, p<0.001) and 0.138 (t=6.489, p<0.001) higher than their respective baseline scores. Patients who received CT had the least increase in mean overall health-related QoL of 0.095 (t=4.574, p<0.001) from baseline. Conclusion: Chemoradiation therapy and adjuvant chemotherapy were associated with highest increase in mean overall health-related QoL. Chemotherapy was associated with the least increase in mean overall health-related QoL.

Risk and protective factors associated with depression in young people: what do Nigerian university students know?

Background: University students appear to experience a significantly higher rate of depression compared to the general population. However, there is limited data showing how much Nigerian university students know about the risk and protective factors related to depression. Objectives: To assess the knowledge of risk and protective factors associated with depression in young people among students of a Nigerian university. Methods: A cross-sectional descriptive survey was conducted among simple randomly selected students of the University of Nigeria, Nsukka. Two validated self-administered questionnaires were used for data collection. Descriptive statistics and multivariate binary logistic regression were used for the data analysis. Results: Out of 1591 participants, about 47% and 60% had good knowledge of risk and protective factors related to depression, respectively. The course of study, year of study, contact with a depressed person, and personal experience of depression significantly predicted students' knowledge of risk factors for depression. Similarly, course of study, year of study, and gender were the significant predictors of students' knowledge of protective factors against depression. Conclusions: The students had good knowledge of protective factors against depression, but were poor in knowledge of its associated risks. Therefore, provision of mental health services in the universities is recommended.

Development and reliability testing of a cervical cancer patients knowledge and practice of self-care management of treatment-related adverse events questionnaire.

INTRODUCTION: Cervical cancer (CC) treatment-related adverse events (AEs) were found to be among the major reasons for treatments delays and medication non-adherence. Knowledge and practice of self-care management of these AEs are therefore needed to complement the pharmacotherapeutic interventions. Instruments for assessing CC patients' knowledge and practice of self-care management of treatment-related Adverse Events (AEs) are lacking. Hence, the rational for this study. METHODS: A prospective, cross-sectional study was conducted on CC patients receiving chemotherapy, radiotherapy or both, with or without surgery in Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto, a tertiary hospital in North-Western Nigeria. A panel of 14 experts judged the content validity of the items initially selected. Purposive sampling technique was used, 31 CC patients were recruited and interviewed for the questionnaire pre-testing. Descriptive statistics and psychometric analysis were conducted using SPSS Version 20.0 for Windows. A Cronbach's alpha coefficient ≥0.70 was considered acceptable. RESULTS: A 12-domain questionnaire instrument was developed. Eight (57.1%) of the expert panelists rated the questions' items as "Very good for the study" and none of them rated any of the content "not relevant for the study". The reliability studies showed that the overall knowledge and practice questions response rates were 71.0% and 77.4% and Cronbach's alpha (α) values were 0.956 and 0.913, respectively. CONCLUSION: A reliable, 12-domain cervical cancer patients' knowledge and practice of self-care management of treatment-related adverse events questionnaire was developed. Further research on the psychometric qualities of the instrument is needed.

Prevalence of Low Birth Weight before and after Policy Change to IPTp-SP in Two Selected Hospitals in Southern Nigeria: Eleven-Year Retrospective Analyses.

BACKGROUND: In 2005, Nigeria changed its policy on prevention of malaria in pregnancy to intermittent preventive treatment with sulphadoxine-pyrimethamine (IPTp-SP). Indicators of impact of effective prevention and control of malaria on pregnancy (MIP) are low birth weight (LBW) and maternal anaemia by parity. This study determined the prevalence of LBW for different gravidity groups during periods of pre- and postpolicy change to IPTp-SP. METHODS: Eleven-year data were abstracted from the delivery registers of two hospitals. Study outcomes calculated for both pre- (2000-2004) and post-IPTp-SP-policy (2005-2010) years were prevalence of LBW for different gravidity groups and risk of LBW in primigravidae compared to multigravidae. RESULTS: Out of the 11,496 singleton deliveries recorded within the 11-year period, the prevalence of LBW was significantly higher in primigravidae than in multigravidae for both prepolicy (6.3% versus 4%) and postpolicy (8.6% versus 5.1%) years. The risk of LBW in primigravidae compared to multigravidae increased from 1.62 (1.17-2.23) in the prepolicy years to 1.74 (1.436-2.13) during the postpolicy years. CONCLUSION: The study demonstrated that both the prevalence and risk of LBW remained significantly higher in primigravidae even after the change in policy to IPTp-SP.

Comparison of the effectiveness of two-dose versus three-dose sulphadoxine-pyrimethamine in preventing adverse pregnancy outcomes in Nigeria.

BACKGROUND & OBJECTIVES: : Three doses of intermittent preventive treatment with sulphadoxine-pyrimethamine (IPTp-SP) has been adopted as the new recommendation for prevention of malaria in pregnancy. This study evaluated the effectiveness of two-dose versus three-dose of SP for IPTp-SP in the prevention of low birth weight (LBW) and malaria parasitaemia. METHODS: : An open, randomized, controlled, longitudinal trial was conducted in a secondary level hospital in Nsukka region of Enugu State, Nigeria. A sample of 210 pregnant women within gestational ages of 16-24 wk were recruited at antenatal clinics and equally randomized to either a two-dose SP or three-dose SP group. The primary endpoints were LBWs, peripheral, and placental parasitaemia, while the secondary endpoints were maternal anaemia, pre-term birth, clinical malaria and adverse effects of SP. RESULTS: : Among 207 cases followed till delivery, the prevalence of parasitaemia was lower in three-dose group than in two-dose group for both peripheral (9.3% versus 27.8%) and placental (10.6% versus 25.6%) parasitaemia. The adjusted odds ratios (aOR) were 0.15 [95% confidence interval (CI), 0.05 - 0.45] and 0.17 (95% CI, 0.06-0.51), respectively. The prevalence of LBW was also lower in three-dose (3.5%) than in two-dose (12.2%) group (aOR, 0.15; 95% CI, 0.04-0.63); however, the prevalence of maternal anaemia, pre-term births, clinical malaria and SP adverse effects were similar between the two arms of treatment. INTERPRETATION & CONCLUSION: : Addition of a third SP dose to the standard two-dose SP for IPTp led to improved reductions in the risk of some adverse pregnancy outcomes.

Awareness, Knowledge and Attitudes Towards Cervical Cancer Amongst HIV-Positive Women Receiving Care in a Tertiary Hospital in Nigeria.

The incidence of cervical cancer (CC) in the sub-Saharan Africa region, where Nigeria is located, is amongst the highest in the world; it is estimated that 70,722 new cases of invasive cervical cancer occur annually in sub-Saharan Africa. Immunosuppression, especially due to human immunodeficiency virus (HIV) infection, is a predisposing factor for persistent infection with high-risk human papilloma virus (HR-HPV) and the development of squamous intraepithelial lesions. Four hundred and fifty women who attended the HIV clinic at the Nnamdi Azikiwe University Teaching Hospital, Nnewi, and who consented to participate in the study were randomly selected. They were given self-administered questionnaires which sought to determine their awareness and knowledge of cervical cancer and attitudes towards cervical cancer screening and prevention. The media 23% (n = 103) was the most common source of information amongst respondents who had heard about cervical cancer. For all the women surveyed, the average percentage knowledge was 9.95%. Having attitude scores greater than or equal to the mean attitude score of 55.16% was regarded as having a positive attitude while a score lower than that was regarded as negative attitude. About 43.5% (n = 195) respondents had a positive attitude towards cervical cancer screening and prevention. Cervical cancer awareness and knowledge amongst women attending the HIV clinic in the Nnamdi Azikiwe University Teaching Hospital, Nnewi, were very poor. Their attitude towards cervical cancer screening practices and prevention was also very poor.

Medication adherence in type 2 diabetes patients in Nigeria.

BACKGROUND: Medication adherence is a major universal factor influencing patient health outcomes, particularly in chronic diseases such as diabetes. Poor adherence to antidiabetes medication can cause therapeutic failure, leading to manifestation of diabetes-related complications, such as retinopathy, neuropathy, nephropathy, etc., reduced quality of life, and increased healthcare costs. To forestall these, likely predictors of medication nonadherence should be assessed and addressed appropriately. The purpose of this work was therefore to assess medication adherence among type 2 diabetes patients and to identify patient characteristics and probable factors associated with nonadherence. SUBJECTS AND METHODS: A descriptive, cross-sectional research design was used. The study was conducted on 360 ambulatory type 2 diabetes patients attending an endocrinology clinic between June 2012 and February 2013. The eight-item Modified Morisky Adherence Scale was used to assess medication adherence; sociodemographic information and respondents' opinion on the possible barrier(s) to medication adherence were also obtained. Data were analyzed using SPSS version 14.0 software (SPSS, Inc., Chicago, IL). RESULTS: Of the 303 patients included in the final analysis, 19.8% of respondents were judged to be highly adherent. Medium and low adherers were 30.0% and 50.2%, respectively. The median adherence score was 5.75 (interquartile range, 4.5-7.0). Adherence to medication correlated with low literacy level (P=0.008), forgetfulness (P=0.009), high cost of medication (P=0.014), limited access to care (P=0.001), complexity of regimen (P=0.001), poor patient-provider communication (P=0.000), lack of trust in the provider (P=0.046), and depression (P=0.031). No statistically significant relationship was found between patients' characteristics and medication adherence. CONCLUSIONS: Medication adherence was generally poor among the cohorts studied.

Knowledge of self-care among type 2 diabetes patients in two states of Nigeria.

OBJECTIVE: To assess the knowledge of self-care practices, as well as factors responsible for such knowledge among type 2 diabetes patients in two states of Nigeria. METHODS: Descriptive, cross sectional survey research design was employed. The study was conducted on type 2 diabetes out-patients attending Endocrinology Clinic at the University of Uyo Teaching Hospital (UUTH) and University of Calabar Teaching Hospital (UCTH) between June 2012 and February 2013. The Diabetes Self-care Knowledge (DSCK-30) was used in evaluating knowledge of self-care practices. Socio-demographic information and respondents' opinion on the possible barrier(s) to knowledge of self-care were also obtained. Data were analysed using Microsoft Excel and SPSS version 14.0. Statistical significance for all analyses was defined as a p value less than 0.05. RESULTS: A total of 303 out of 380 questionnaires distributed were completed and returned (response rate =79.7%). The majority of the study sample (79.5%) had 70% or more overall knowledge level about self-care. Self-care knowledge was associated with level of education (p<0.001), monthly income (p<0.001) and duration of diabetes (p=0.008). Negative attitude to disease condition was the only factor associated with knowledge (chi-square value at one degree of freedom =6.215; p=0.013). CONCLUSION: Diabetes self-care knowledge was generally high among the population studied. Educational status, monthly income, duration of diabetes and negative attitude to disease condition predicted knowledge level.

Student pharmacists' career choices: a survey of three Nigerian schools of pharmacy.

BACKGROUND: There is little data on the preferences of pharmacy students as regards their future pharmacy job choices in Africa and this has created concerns amongst licensing bodies, employers and also the institutions they graduate from. OBJECTIVE: Career choices and factors that influence these choices of pre-registration pharmacists were assessed. METHODS: Final and fourth year students from three schools of pharmacy were approached with a previously validated and employed questionnaire comprising questions on future job choices and reasons for that job choice. Data collected were subjected to descriptive and inferential analysis. RESULTS: Four hundred and eighty eight students took part in the study (response rate 71.5%). Majority (78.8%) was younger than 26 years and had a work experience (68.2%). Job flexibility was significantly more important to females, while younger students considered salary most important (p<0.05). Hospital and community practice were most preferred career choices. Other demographic factors (especially gender, marital status, previous degree and previous work experience) significantly affected career choices. CONCLUSIONS: Age, gender, and previous work experience affect career choices of graduating pharmacy students. Patient-oriented practices (e.g. hospital and community) remain the most preferred careers.

Cost-Utility Analysis of Pharmaceutical Care Intervention Versus Usual Care in Management of Nigerian Patients with Type 2 Diabetes.

OBJECTIVE: To assess the cost-effectiveness of pharmaceutical care (PC) intervention versus usual care (UC) in the management of type 2 diabetes. METHODS: This study was a randomized, controlled study with a 12-month patient follow-up in two Nigerian tertiary hospitals. One hundred and ten patients were randomly assigned to each of the "intervention" (PC) and the "control" (UC) groups. Patients in the UC group received the usual/conventional care offered by the hospitals. Patients in the PC group received UC and PC in the form of structural self-care education and training for 12 months. The economic evaluation was based on patients' perspective. Costs of management of individual complications were calculated from activities involved in their management by using activity-based costing. The impact of the interventions on quality of life was estimated by using the HUI23S4EN.40Q (Mark index 3) questionnaire. The primary outcomes were incremental cost-utility ratio and net monetary benefit. An intention-to-treat approach was used. Two-sample comparisons were made by using Student's t tests for normally distributed variables data at baseline, 6 months, and 12 months. Comparisons of proportions were done by using the chi-square test. RESULTS: The PC intervention led to incremental cost and effect of Nigerian naira (NGN) 10,623 ($69) and 0.12 quality-adjusted life-year (QALY) gained, respectively, with an associated incremental cost-utility ratio of NGN 88,525 ($571) per QALY gained. In the cost-effectiveness acceptability curve, the probability that PC was more cost-effective than UC was 95% at the NGN 250,000 ($1613) per QALY gained threshold and 52% at the NGN 88,600 ($572) per QALY gained threshold. CONCLUSIONS: The PC intervention was very cost-effective among patients with type 2 diabetes at the NGN 88,525 ($571.13) per QALY gained threshold, although considerable uncertainty surrounds these estimates.

The Impact of Pharmaceutical Care Intervention on the Quality of Life of Nigerian Patients Receiving Treatment for Type 2 Diabetes.

OBJECTIVES: To evaluate the impact of pharmaceutical care (PC) intervention on health-related quality of life (HRQOL) of patients with type 2 diabetes. METHODS: This study was a randomized, controlled study with a 12-month patient follow-up. The study protocol was approved by the Research Ethical Committees of the institutions in which this study was conducted. A total of 110 patients were randomly assigned to each of the "intervention" (PC) and "control" (usual care [UC]) groups. Patients in the UC group received the usual/conventional care offered by the hospitals. Patients in the PC group received UC and additional PC for 12 months. The HUI23S4EN.40Q (developed by HUInc - Mark index 2&3) questionnaire was used to assess the HRQOL of the patients at baseline, 6 months, and 12 months. Two-sample comparisons were made by using Student's t tests for normally distributed variables or Mann-Whitney U tests for nonnormally distributed data at baseline, 6 months, and 12 months. Comparisons of proportions were done by using the chi-square test. RESULTS: The overall HRQOL (0.86 ± 0.12 vs. 0.64 ± 0.10; P < 0.0001) and single attributes except "hearing" functioning of the patients were significantly improved at 12 months in the PC intervention arm when compared with the UC arm. The HRQOL utility score was highly negatively (deficit ≥10%) associated with increasing age (≥52 years), diabetes duration (>4 years), emergency room visits, comorbidity of hypertension, and stroke in both PC and UC groups. CONCLUSION: Addition of PC to UC improved the quality of life in patients with type 2 diabetes.

Health state utilities of a population of Nigerian hypertensive patients.

BACKGROUND: Establishment of the health impact of hypertension on quality of life of Nigerians is a step towards controlling the disease. The study aimed to provide a Nigerian specific reference list of utility scores of hypertensive patients with various interacting conditions. FINDINGS: An interviewer-based, cross-sectional study was conducted using hypertensive patients in two purposively selected tertiary hospitals located in South-Eastern Nigeria. Health Utility Index Mark 3 (HUI3) was used.A total of 384 participants with either hypertension alone or with hypertension-associated complications were interviewed in the two tertiary hospitals.The overall mean utility score was 0.35 +/- 0.42. Patients with hypertension alone had the highest overall mean utility score (0.57 +/- 0.29) while hypertensive patients with stroke had the lowest overall mean score (0.04 +/- 0.36). Being a male, increase in age and mean arterial blood pressure, emergency visit and loss of work due to illness were associated with significant decrease in overall utility scores. CONCLUSIONS: This study presented a reference for health state utilities of a population of Nigerian hypertensive patients.
