Assessment of drug use in primary health centers in Lagos State, Nigeria.

Introduction: rational drug use prevents wastage of resources, loss of confidence in healthcare system and drug-related morbidity and mortality. This study aims to assess drug use in Primary Health Centers (PHCs) in Lagos State, Nigeria using the World Health Organization in collaboration with the International Network of Rational Use of Drugs core drug use indicators. Methods: the study was conducted between February to October 2021 as a comparative observational survey of selected PHCs. It included a retrospective and prospective cross-sectional design for prescribing and patient care indicators assessing 2640 prescriptions and clients respectively. Data were analyzed and presented as frequency with percentage or mean with standard deviation, as applicable. The performances of the types of PHCs were compared using two-sample t-test. A 2-tailed p-value < 0.05 was considered statistically significant. Results: average number of drugs per prescription, drugs prescribed by the generic name, percentage of encounters with prescribed antibiotics and injections were 3.6 ± 0.9%, 76.5 ± 18.5%, 63.3 ± 19.1% and 21.1 ± 24.1% respectively with no significance difference between the comprehensive and basic PHCs. For all the facilities, the average consultation and dispensing times were 10.5 ± 6.0 minutes, 244.9 ± 179.2 seconds respectively. In this study, the percentage of patients' knowledge of the correct dosage was 72.4 ± 38.3%. There is statistically significant difference in availability of key drugs in stock between the comprehensive and basic PHCs (p-value 0.0001). Conclusion: irrational drug use practices exist in comprehensive and basic PHCs. There is a need to implement interventions aimed at strengthening good prescribing and patient-care practices across the PHCs in Lagos State.

Adolescents and Young Adults Knowledge, Adherence and Experiences While on Antiretroviral Therapy in a Tertiary Hospital in Lagos, Nigeria: A Mixed-Method Study.

In Nigeria, there is a paucity of data on knowledge and experiences of adolescents and young adults (AYAs) with HIV and ART, as well as their challenges maintaining optimal adherence. A mixed-method study was carried out between August and September 2018 among AYAs attending Lagos University Teaching Hospital, Nigeria. Data collection was via AYAs' hospital records, standardized questionnaires, and in-depth interviews (IDIs). The 4-day ACTG tool was used to measure adherence. Collected data were analyzed descriptively. Assessment of 34 AYAs comprising 18 (52.9%) males with 28 (82.4%) students revealed an overall knowledge score about ART and its effect of 73.6%. Twenty-five (73.5%) had poor knowledge of the development of resistant strains of HIV due to non-adherence recorded. Optimal adherence (≥95%) was recorded in 20 (58.8%) AYAs. IDI produced 4 themes: (i) reasons for non-adherence, (ii) ensuring optimal adherence, (iii) Social support systems and disclosure, and (iv) stigmatization. Our study provided formative data and revealed areas for intervention to improve knowledge and adherence to ART.

Impact of pharmacist-led care on glycaemic control of patients with uncontrolled type 2 diabetes: a randomised controlled trial in Nigeria.

BACKGROUND: Diabetes mellitus is a chronic, degenerative disease, requiring a multi-dimensional, multi-professional care by healthcare providers and substantial self-care by the patients, to achieve treatment goals. OBJECTIVE: To evaluate the impact of pharmacist-led care on glycaemic control in patients with uncontrolled Type 2 Diabetes. METHODS: In a parallel group, single-blind randomised controlled study; type 2 diabetic patients, with greater than 7% glycated haemoglobin (A1C) were randomised into intervention and usual care groups and followed for six months. Glycated haemoglobin analyzer, lipid analyzer and blood pressure monitor/apparatus were used to measure patients' laboratory parameters at baseline and six months. Intervention group patients received pharmacist-structured care, made up of patient education and phone calls, in addition to usual care. In an intention to treat analysis, Mann-Whitney U test was used to compare median change at six months in the primary (A1C) and secondary outcome measures. Effect size was computed and proportion of patients that reached target laboratory parameters were compared in both arms. RESULTS: All enrolled participants (108) completed the study, 54 in each arm. Mean age was 51 (SD 11.75) and majority were females (68.5%). Participants in the intervention group had significant reduction in A1C of -0.75%, compared with an increase of 0.15% in the usual care group (p<0.001; eta-square= 0.144). The proportion of those that achieved target A1C of <7% at 6 months in the intervention and usual care group was 42.6% vs 20.8% (p=0.02). Furthermore, intervention patients were about 3 times more likely to have better glucose control; A1C<7% (aOR 2.72, 95% CI: 1.14-6.46) compared to usual care group, adjusted for sex, age, and duration of diabetes. CONCLUSIONS: Pharmacist-led care significantly improved glycaemic control in patients with uncontrolled T2DM.

Drug therapy problems identified among patients receiving antiretroviral treatment in a HIV clinic: a prospective study in North Central, Nigeria.

INTRODUCTION: despite improved life expectancy for people living with HIV (PLWH), aging, comorbidities, and associated drug treatment increase the risk for drug therapy problems (DTPs). We assessed pharmacists´ identification and resolution of DTPs among PLWH. METHODS: a prospective study was conducted among PLWH aged ≥10 years (N=100) in a Nigerian HIV clinic. Trained pharmacists delivered a six-step intervention that included the establishment of patient-provider relationship, gathering and validation of patient´s data, identification of DTPs, intervention, outcome identification, and documentation. Descriptive statistics were used to examine data collected via a pharmaceutical care assessment tool. RESULTS: in all, 215 DTPs were identified and classified as unnecessary drug therapy [27.4% (n=59)], non-adherence [21.9% (n=47)], needs additional drug therapy [16.7% (n=36)], adverse drug reaction [(14.0% (n=30)], wrong drug [(10.7% (n=23)], and dosage variation [n=20 (9.3%)]. Within each DTP class, the most common cause was addiction/recreational drug use [39.0% (n=23)], drug product not available [63.8% (n=30)], untreated condition(s) [61.1% (n=22)], undesirable effects [66.7% (n=20)], condition refractory to drug [34.8% (n=8)], and drug interaction [45.0% (n=9)], respectively. The most common interventions were medication information/recommendation to patients/prescribers (30.4%) and initiation of drug therapy (22.2%). Six-month resolution rate was 90% (n=194) with the most common outcomes being improvement in patient adherence [23.6% (n=50)], addition of a drug [18.9% (n=40)], and reduction in drug overuse [15.6% (n=33)]. CONCLUSION: pharmacists´ intervention resulted in 90% resolution of detected DTPs, implying that pharmacists are crucial in improving antiretroviral treatment outcomes.

Comparative incidence of adverse drug reaction during the first and subsequent year of antiretroviral therapy in a Nigerian HIV infected Cohort.

BACKGROUND: Despite close to two decades of antiretroviral therapy (ART) in Nigeria, data on late on-onset ART-associated adverse drug reactions (ADRs) are sparse. OBJECTIVES: To describe early and late-onset ADRs and compare their incidence in an outpatient HIV positive Cohort on ART. METHOD: We described the incidence of clinical ADRs identified and documented in an outpatient clinic cohort of HIV-positive patients treated between June 2004 and December 2015 at a tertiary health facility in Nigeria. Incidence rates of ADRs during the first and subsequent years of ART were compared. RESULTS: of the 13,983 patients' data analyzed, 9317 were females (66%), and those in the age bracket of 25 to 45 years made up 78% of the studied population. During 52,411 person-years (py) of ART, 1485 incident ADRs were recorded; Incidence rate (IR) 28.3 (95% confidence interval [CI] 26.9:29.8) ADRs per 1000 person-years (py) of ART. The IR of ADRs was about two times higher in the first year of ART compared to subsequent years of treatment; crude incidence rate ratio (IRR) 1.77 (95% CI 1.59:1.97). Anemia, hypersensitivity reactions, and nervous system disorders had 7, 23, and 5 times higher incidence, respectively, in the first year of therapy, compared to subsequent years. CONCLUSION: The first year of ART is the period of highest risk of ADRs. Individual and programmatic treatment success in resource-limited settings requires strategies for early identification and management of ADR during the period of greatest risk of ADRs.

Prevalence of ethanol and other potentially harmful excipients in pediatric oral medicines: survey of community pharmacies in a Nigerian City.

OBJECTIVE: Excipients are needed in the formulation of oral liquid medicines intended for children; they have however been reported to trigger safety issues. This study evaluated the concentrations and prevalence of ethanol and other potentially harmful excipients in pediatric formulations marketed in South Eastern Nigeria in line with international labeling guidelines and allowable daily limits (ADL). The study sampled oral pediatric formulations offered for sale in registered pharmacies. Those with accessible information leaflets were assessed for the presence and quantity of previously flagged excipients with potential to harm the pediatric population. RESULT: Of the 380 oral pediatric medicines, 140 provided access to list/quantity of ingredients. 47.9% (67) of the formulations contain at least one of the flagged excipients while the remaining only listed the active ingredients. Ethanol had the highest occurrence (62.7%) and was more in cough/cold medicines. A homeopathic cough and cold remedy had concentration of 90% v/v. Ethanol and sucrose in some formulations exhibited concentrations with a potential of crossing their approved daily intake (ADI) (1-90% v/v and 1.7 g-3.7 g/5 ml respectively). Ethanol use in studied pediatric formulations was quite high, with ethanol-containing formulations being prescribed for children 0-6 years and older. Only 26 (38.8%) completely satisfied the labelling requirements for ethanol containing formulations.

Herbal medicine use among Type 2 diabetes mellitus patients in Nigeria: understanding the magnitude and predictors of use.

Background Patients with chronic diseases exploit complementary and alternative treatment options to manage their conditions better and improve well-being. Objective To determine the prevalence and predictors of herbal medicine use among Type 2 Diabetes patients in Lagos, Nigeria. Setting Secondary healthcare facilities in Lagos state, Nigeria. Method The study design was a cross sectional survey. A two-stage sampling approach was used to select the health facilities and patients were recruited consecutively to attain the sample size. Data was collected using a structured and standardized interviewer-administered questionnaire. Characteristics, prevalence and predictors of herbal medicine use were assessed using descriptive statistics and multivariate regression analyses. Main outcome measure Herbal medicine use among Type 2 diabetes mellitus patients. Results 453 patients were surveyed, 305 (67.3%) reported herbal medicine use, among whom 108 (35.4%) used herbal and conventional medicines concurrently; 206 (67.5%) did not disclose use to their physician. Herbal medicine use was significantly associated with age (p = 0.045), educational level (p = 0.044), occupation (p = 0.013), duration of diabetes disease (p = 0.007), mode of diabetes management (p = 0.02), a positive history of diabetes (p = 0.011) and presence of diabetes complication (p = 0.033). Formulations or whole herbs of Vernonia amygdalina, Moringa oleifera, Ocimum gratissimum, Picralima nitida, and herbal mixtures were the commonest herbal medicine. Beliefs and perceptions about herbal medicine varied between the users and non-users. Conclusion The use of herbal medicine among Type 2 diabetes mellitus patients in Lagos, Nigeria is high. There is dire need for health care practitioners to frequently probe patients for herbal medicine use and be aware of their health behaviour and choices, with a view to manage the disease better.

Effect of 2 Models of Care and Factors Predicting Patients' Adherence to Doctor's Appointment Attendance in Lagos State University Teaching Hospital, Ikeja, Lagos, Nigeria.

BACKGROUND: Provision of antiretroviral therapy in resource limited settings has put pressure on the available infrastructure. OBJECTIVES: The study examined patients' adherence to Doctor's appointment attendance after an intervention changing the model of care and factors that predicted adherence. METHODS: Observational study was carried out over four years. The model of care was changed in the last year and the effect assessed. SPSS version 15.0 was used for analysis. Predictors of adherence were determined using logistic regression model. RESULTS: Over half 148 (59.7%) of the patients were females, with a mean age of 40.4±8.8 years and baseline CD4 cells of 143.5±92.7cells/microliters. "Adherence" rates were 51.3% in 2007, 35.9% in 2008 and 14.9% in 2009 giving patients' average adherence to Doctor's appointment attendance of 34.03%. Intervention changing the model of care in 2010 recorded an adherence rate of 93.1%. CONCLUSIONS: The change in model of care greatly improved patients' "adherence". Patients' knowledge of management, adherence, and smoking and drinking habits were identified as statistically significant predictors of adherence.

Management of acute diarrhea in children by community pharmacists in Lagos, Nigeria.

BACKGROUND: Acute diarrhea in children leads to dehydration and death if not appropriately managed. World Health Organization (WHO) recommends treating diarrhea with oral rehydration therapy (ORT), fluids and foods. Proper management is hinged on accurate assessment of patients to identify the acute watery diarrhea. OBJECTIVE: To compare the knowledge and attitude of community pharmacists in the management of acute diarrhea in children with their observed practice. METHODS: THIS STUDY WAS CARRIED OUT USING TWO INSTRUMENTS: structured self-administered questionnaire to assess knowledge and attitude of community pharmacists in the management of acute diarrhea in children and simulated patient visits to evaluate assessment of patients, recommendation of products and instructions on feeding and fluid intake. The simulated patient visits were done in 186 pharmacies in the city of Lagos, Nigeria. RESULTS: The study reveals that the knowledge and attitude of community pharmacists in the management of acute diarrhea in children was different from their observed practice. The difference was statistically significant (p<0.05). During the simulations, 23% carried out appropriate assessment before recommending any products, and 15% recommended ORT alone. Although information to the pharmacists indicated non-dysentery, non-cholera, acute watery diarrhea, antibiotics and antidiarrheals were irrationally recommended and these were the mainstay of symptoms' management in practice. Questionnaire data revealed that 24% of pharmacists knew the correct instructions to give on food and fluid intake during diarrhea, whereas 8% followed WHO guideline on food and fluid intake during the visits. CONCLUSIONS: Assessment of patients to determine acute diarrhea was inadequate. Observed practice in managing acute diarrhea in children was inappropriate and significantly different from their claims in the questionnaire. The recommendation of ORT was scanty and advice on food and fluid intake was inadequate and sometimes inappropriate. This study shows that only 15% of community pharmacists managed acute diarrhea in children according to the WHO guidelines.
