Drug take-back program: assessment of knowledge, practices, and barriers to safe disposal of unused medication among healthcare students in a Nigerian university.

BACKGROUND: The safe disposal of unused medication is a critical public health issue, with risks including environmental pollution, accidental ingestion, and misuse. Inadequate adherence to proper disposal methods among healthcare students could affect the practice of safe disposal of unused medicines as future healthcare professionals. This study, conducted at a Nigerian university, aimed to assess the knowledge, adherence to safe disposal practices, and barriers faced by healthcare professional students regarding unused medication disposal. METHODS: A cross-sectional study was carried out among 930 healthcare students in a Nigerian University, comprising medical and surgery, nursing, pharmacy, physiotherapy, and medical laboratory science students. Information was gathered from respondents using a self-administered questionnaire. Multivariate analyses were used to evaluate the relationship between specific variables and participants' knowledge and practice scores, while chi-square and logistic regression tests were used for categorical variables at p < 0.05. RESULTS: A total of 930 students participated in this study. The results revealed a significant gap in knowledge, with (67.7%; 630) of the participants unaware of proper disposal methods and most scoring either 0 (31.9%; 297) or 1 (46.0%; 428) out of 4 on a knowledge-based questionnaire. Pharmacy students were the most knowledgeable, with 44.4% falling into the high knowledge category. However, their knowledge did not always correspond to correct practices, with only (10.1%; 94) of participants reporting use of recommended disposal methods such as returning unused medicine to a pharmacy or a drug take-back program. Significant associations were found with course of study (χ²=12.14, p = 0.033) and awareness of correct disposal methods (χ²=4.035, p = 0.045). Those aware of the correct disposal method had a higher odds ratio of high knowledge score (OR = 1.62, 95% CI: 1.1-2.41, p = 0.018) compared to those who were not aware. In terms of disposal practices, those who had received training on safe disposal had significantly higher odds of good practice score (OR = 2.25, 95% CI: 1.36-3.74, p = 0.002). Major barriers identified included lack of access to drug take-back programs (50.4%; 469), lack of knowledge (36.8%; 342), and inconvenience (10.3%; 14). CONCLUSION: A knowledge gap was revealed among the respondents regarding the safe disposal of unused medications. Despite the presence of knowledge and awareness, these do not necessarily translate into good disposal practices. This call for strategies to overcome identified barriers, with the aim to bridge the knowledge-practice gap and promote safe disposal of unused medication. The study underscores the urgent need for improved public health policies and educational programs on safe medication disposal.

Antimicrobial stewardship: Assessment of knowledge, awareness of antimicrobial resistance and appropriate antibiotic use among healthcare students in a Nigerian University.

BACKGROUND: Inappropriate use of antibiotics is a major cause of antimicrobial resistance (AMR). Inadequate knowledge about AMR among healthcare students could affect their practice of antimicrobial stewardship as future healthcare professionals. This study aims to assess the use of antibiotics and knowledge of AMR among future healthcare professionals of a Nigerian University. METHODS: Respondents' knowledge of antimicrobial resistance, use of antibiotics, and source of antibiotics in the past 12 months was explored using a self-administered questionnaire. Multivariate analyses were used to evaluate the relationship between specific variables and respondents' knowledge. RESULTS: Of the 939 questionnaires administered to the students, 866 were filled given a response rate of 92.2 %. A total of (765; 88.3 %) of the respondents were aware that antimicrobial resistance makes it harder to eliminate the infection from the body as existing drugs become less effective. In all 824, (95.2 %) of the respondents had use antibiotics in the past 12 months. The use of antibiotics to treat malaria was self-reported by (175; 21.2 %). About half (432; 52.4 %) purchased the antibiotics from community pharmacies, while others obtained their antibiotics from the hospitals (192; 23.3 %), patent medicine stores (150; 18.2 %), and friends and family (50; 6.1 %) in the last 12 months. In all 506, (58.4 %) had good knowledge of antimicrobial resistance. Logistic regression shows that students in 3rd to 6th year 9.29 [AOR = 9.29, 95 % CI: (3.7-22.96)], had greater knowledge of antimicrobial resistance. CONCLUSIONS: The healthcare students demonstrated a moderate knowledge of AMR. This underscores the need to adopt several educational tactics to introduce the concepts of AMR to the students and ensure there are strict policies to regulate the flow of antibiotics.

Pharmacists' knowledge and counselling on fall risk increasing drugs in a tertiary teaching hospital in Nigeria.

BACKGROUND: Falls and fall-related injuries are a foremost health concern among older adults aged 60 years and above. Fall-risk-increasing drugs (FRIDs) use by older adults is one related cause of falling, and it is frequently used among older adults. Pharmacist-led counselling is an aspect of patient education that has been associated with improved therapeutic outcome and quality of life in high income countries with scarcity of information in low-middle income countries. This study therefore aims to assess hospital pharmacists' knowledge and counselling on fall-related medications using the list compiled by the Swedish National Board of Health and Welfare on FRIDs and orthostatic drugs (ODs). METHODS: A cross-sectional survey was carried out among 56 pharmacists working in a teaching hospital in Nigeria, between July and August 2019, using a self-administered questionnaire. Data were summarized with descriptive statistics while chi-square test was used for categorical variables at p < 0.05. RESULTS: Thirty-five (62.5%) were within 10 years of practice experience. Two-third (62.5%) of the pharmacists possessed an additional qualification to Bachelor of Pharmacy degree. Twenty-two (40.0%) were aware of the FRIDs and ODs list. In all, (89.3%) had "unsatisfactory" knowledge of classes of medications and specific medicines that could cause a fall. Most pharmacists 42 (80.8%) focused counsel on appropriate medication use, adverse effects of drugs and storage of medications. Knowledge score of both FRIDs and ODs were neither significantly associated with pharmacists' years of qualification (χ2 = 1.282; p = 0.733), (χ2 = 2.311; p = 0.510) nor with possession of additional qualification (χ2 = 0.854; p = 0.836), (χ2 = 2.996; p = 0.392). Majority, 53 (98.1%) believed that patients will benefit from effective counselling on FRIDs and ODs. About half (25; 51.0%) suggested training through seminar presentation as a measure for FRIDs and ODs sensitization. CONCLUSION: A substantial gap in knowledge and awareness of FRIDs and ODs was noted among the hospital pharmacists. However, engagement of pharmacists on counsel that focus on medication use, adverse effect and storage was relatively better. Thus, there is a general need to create awareness about fall-risk-increasing drugs among hospital pharmacists, so as to help improve the therapeutic outcome particularly in the older adults.

Extent of misuse and dependence of codeine-containing products among medical and pharmacy students in a Nigerian University.

BACKGROUND: Misuse and dependency of opioids especially codeine-containing products is of increasing global concern. Inappropriate use of opioids among healthcare students could affect quality of service and ethical conducts of these future professionals, thereby putting the society at risk. This study aimed to evaluate knowledge and perception of medical and pharmacy students in a Nigerian tertiary University on use of opioids with focus on codeine-containing products. METHODS: A cross-sectional survey among 335-medical and 185-pharmacy students from University of Ibadan, Nigeria, between September and December 2018, using a self-administered semi-structured questionnaire. RESULTS: A total of 178 (34.2%) in multiple responses had used opioid-containing products among the respondents, of this, 171 (96.1%) used codeine-containing formulation. Precisely, 146 (28.1%) of the students had used codeine-containing products before, of this, 16 (11.0%) used the products for non-medical or recreational purpose regarded as a misuse/abuse. In all, 201 (38.7%) had good knowledge of opioid use, with 51 (34.9%) among those who had used opioids and 150 (40.1%) among those who had not used opioids (X2 = 1.186; p = 0.276). Majority (469; 90.2%) had good perception of risks associated with opioid use; comprising (130; 89.0%) among those who had taken opioids and (339; 90.6%) among those who had not taken opioids before (X2 = 0.304; p = 0.508). Logistic-regression shows that students who experienced some side effects to be experienced again 22.1 [AOR = 22.1, 95% CI: (5.98-81.72)] as well as those pressured into using codeine-containing products 10.6 [AOR = 10.6, 95% CI: (1.36-82.39)] had more tendency of misuse. CONCLUSION: There is a potential for misuse of codeine-containing products among medical and pharmacy students. Peer-influence and experience of some side effects are possible predictors of misuse among the students. Thus, healthcare students' curriculum should incorporate preventive programme, while public education and policy that favours peer-support programme on medication misuse is advocated for healthcare students.

Self-medication with over-the-counter drugs among consumers: a cross-sectional survey in a Southwestern State in Nigeria.

OBJECTIVES: This study set out to assess the knowledge, perception and practices of consumers regarding self-medication with over-the-counter (OTC) drugs, the prevalence of risky practices and their associated factors in pharmacy outlets in Ibadan, Southwestern Nigeria. SETTING: A cross-sectional study was conducted using an interviewer administered questionnaire. Descriptive statistics and multivariate analysis were performed by using SPSS V.23 with statistical significance set at p<0.05. PARTICIPANTS: 658 adult consumers aged 18 years and above. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was self-medication, measured using the following question: A positive answer indicates a self-medicated participant. Do you practise self-medication? RESULTS: Respondents who had practised self-medication with OTC drugs were 562 (85.4%), of which over 95% were involved in risky practice. Consumers agreed (73.4%) that OTC drugs can be recommended by pharmacists and perceived (60.4%) that OTC drugs are harmless regardless of how they are used. Reasons for practising self-medication with OTC drugs include: if it is a minor condition, I can take the initiative (90.9%), visiting a hospital wastes my time (75.5%) and ease accessibility of the pharmacy (88.9%). Overall, (83.7%) respondents had good practices of handling and use of OTC drugs, while (56.1%) had good knowledge of OTC drugs and identification of OTC drugs. Factors associated with consumer handling and use of OTC drugs in self-medication were older participants (p=0.01), those with postsecondary education (p=0.02), and who possessed good knowledge (0.02), were more likely to practise self-medication with OTC drugs. CONCLUSION: The study revealed a high prevalence of self-medication, good practices towards handling and use of OTC drugs, and moderate knowledge of OTC drugs by the consumers. This underscores the need for policy-makers to introduce measures to enforce consumer education by community pharmacists to minimise the risks of inappropriate self-medication with OTC drugs.

Antimicrobial stewardship: knowledge, perceptions, and factors associated with antibiotics misuse among consumer's visiting the community pharmacies in a Nigeria Southwestern State.

BACKGROUND: In middle-income countries like Nigeria, the misuse of antibiotics by consumers is posing serious threats to public health. This is contributing to the alarming increase in antimicrobial resistance, which is reducing the effectiveness of antibiotics against common infections. This study therefore aimed to assess the knowledge, perceptions, and factors associated with antibiotics misuse among consumers visiting selected community pharmacies. METHODS: This cross-sectional study conducted in Ibadan, Nigeria, aimed at determining factors influencing antibiotics misuse among consumers. The questionnaires were completed by 509 consumers. The analysis was done using SPSS version 26 and the results were presented using descriptive statistics. The associations between categorical variables were analysed using Pearson's Chi-square with statistical significance set at p < 0.05. RESULTS: Results showed that 95.9% of the consumers believed that antibiotics prevent bacterial growth, and 60.7% thought they treat all infections. However, 57.4% were unaware of antibiotic resistance, while only 14.7% had adequate knowledge about antibiotics. Most of the consumers, 72.5% had used antibiotics in the last 12 months and, amoxicillin 42.4% was the most commonly used with, malaria 38.9% as the primary condition for which antibiotics were used. Some of the significant factors influencing antibiotics misuse included delays in test reports (p-value = 0.007), the belief in antibiotics' quick relief (p-value = 0.001), proximity of the pharmacy to their house or workplace (p-value = 0.028), amongst others. CONCLUSION: Most of the consumers had inadequate knowledge about rational antibiotic use which contributed to their misuse of antibiotics. Thus, targeted educational interventions are needed to improve knowledge and promote appropriate antibiotic use among consumers. Policies regulating the dispensing and selling of antibiotics with adequate counselling should be further enforced.

Evaluation of physicians' knowledge of deprescribing, deprescribing tools and assessment of factors affecting deprescribing process.

BACKGROUND : Polypharmacy is a common global health concern in the older population. Deprescribing has been acknowledged as an important aspect of medication use review that helps to reduce polypharmacy, inappropriate medication uses and medication adverse events, thus ensuring medication optimization and improving health-related quality of life. As physicians are primarily responsible for prescribing and monitoring of drug therapy, their perception of deprescribing and knowledge of available deprescribing tools is highly important. This study aimed to explore physicians' knowledge of deprescribing, deprescribing tools and factors that may affect the deprescribing process. METHODS: This was a cross-sectional survey carried out among 70 physicians in selected units of a teaching hospital in Nigeria between May and June 2022. Social-demographic information, knowledge of deprescribing and deprescribing tools were obtained using a self-administered, semi-structured questionnaire, while barriers and enablers of medication deprescribing were assessed with modified Revised Patients' Attitudes Towards Deprescribing (rPATD) Questionnaire. Descriptive and bivariate analyses were carried out using SPSS and α was set at p < 0.05. RESULTS: Most of the physicians (56; 80.0%) were aware of the term "deprescribing" and had good knowledge (53; 75.7%) of the steps to deprescribing. However, (16; 22.9%) respondents knew of the deprescribing tools, of this, (5; 31.3%) were aware of Beers criteria and STOPP/START criteria. Awareness of the term "deprescribing" was significantly associated with knowledge of deprescribing steps (p = 0.012), while knowledge of deprescribing tools was significantly associated with; awareness of the term "deprescribing" (p = 0.029), and daily encounters with older multimorbid patients (p = 0.031). Very important factor affecting physicians deprescribing decisions include benefit of the medication. The most common barrier is lack of information for a full clinical picture of the patient. CONCLUSION: The physicians had good knowledge of the term "deprescribing" and the steps to deprescribing. Specific measures to target the barriers faced by the physicians in deprescribing medications and policies to implement physicians use of existing guidelines to facilitate their deprescribing decisions are essential.

Attitude towards medication deprescribing among older patients attending the geriatric centre: a cross-sectional survey in Southwest Nigeria.

OBJECTIVES: This study set out to assess older people's perception of their medications, attitude towards medication use and their willingness to have medications deprescribed in a geriatric centre in Southwestern Nigeria. DESIGN AND SETTING: A cross-sectional study was conducted at the Chief Tony Anenih Geriatric Centre, University of Ibadan, using an interviewer-administered questionnaire. The questionnaire used was a revised version of the Patient's Attitude Towards Deprescribing Questionnaire. Descriptive statistics, and multivariate and bivariate analyses were performed using SPSS V.23. Statistical significance was set at p<0.05. PARTICIPANTS: 415 older patients aged ≥60 years who attended the geriatric centre in University College Hospital Ibadan between April and July 2022. MAIN OUTCOME MEASURE: The primary outcome was the willingness of the older person to deprescribe if recommended by the physician. RESULTS: The mean age of the participants was 69.6±6.4 years, and 252 (60.7%) were female. Overall, the willingness and positive attitude to medication deprescribing among respondents were 60.5% and 89.7%, respectively. Factors significantly associated with willingness to deprescribe were financial self-support (p=0.021), having no previous hospital admission (p=0.009), better-perceived quality of health relative to peers (p<0.0001), polypharmacy (p=0.003), and the domains burden of medication (p=0.007), medication appropriateness (p<0.0001), concerns about stopping medications (p<0.0001) and involvement with medications (p<0.0001). The predictive factors for improved willingness to deprescribe were direct involvement with medications (OR=2.463; 95% CI 1.501 to 4.043, p<0.0001), medication appropriateness (OR=0.462; 95% CI 0.254 to 0.838, p=0.011) and concerns about stopping medications (OR=2.031; 95% CI 1.191 to 3.463, p=0.009). CONCLUSION: Participants demonstrated greater willingness to deprescribe if the physicians recommended it. Predictive factors that may influence willingness to deprescribe were direct involvement with medications, appropriateness of medication and concerns about stopping medications.

Potentially inappropriate medication use in the elderly: physicians' and hospital pharmacists knowledge, practice, confidence, and barriers.

BACKGROUND: Inappropriate medication prescribing and dispensing by physicians and pharmacists is a preventable cause of morbidity and mortality in the elderly. Signifying the importance of healthcare professionals' knowledge of potentially inappropriate prescribing tools/ guidelines which would improve overall health outcomes. Beers Criteria is one of the most used guidelines that list specific potentially inappropriate medications (PIMs). This study aimed to investigate physicians' and hospital pharmacists' awareness, knowledge, practice, confidence, and barriers to the use of Beers criteria. METHODS: A cross-sectional survey was carried out among 66 hospital pharmacists and 31 family medicine physicians working in a teaching hospital in Nigeria, between May and September 2021 using a self-administered questionnaire. Knowledge of PIMs was assessed using 11 clinical vignettes based on the 2019 Beers Criteria. Practice behavior towards elderly patients was assessed using a 5-item statement with a 5-point Likert scale. Perceived barriers to the appropriate use of Beers Criteria were assessed using a 15-item statement. Descriptive and inferential statistics were used to analyze the data. RESULTS: A total of 66 hospital pharmacists and 31 family medicine physicians participated in the study. Only (24; 36.4%) pharmacists and (4; 12.9%) physicians knew guidelines that listed specific PIMs. In all (21; 31.8%) pharmacists and (11; 35.4%) physicians demonstrated good knowledge of Beers Criteria, while most pharmacists (55; 83.3%) and physicians (29; 93.5%) reported good practice when dealing with elderly patients in terms of asking relevant questions and considering their ages while dispensing medications. Knowledge scores were not significantly associated with hospital pharmacists' socio-demographics. Most of the physicians and pharmacists were confident in the care provided for geriatric patients. The majority (66; 100.0%) pharmacists and (28; 93.5%) physicians suggested training through seminar presentations as a measure to improve the use of Beers' criteria. Lack of time to counsel patients was a major barrier recounted by both physicians and pharmacists. CONCLUSION: Healthcare professionals that participated in this study had satisfactory practice, although a gap in the knowledge of hospital pharmacists and family medicine physicians was noted. In addition to creating awareness among healthcare professionals and training on PIMs and Beers' criteria, a multidisciplinary approach to reduce potentially inappropriate prescribing and dispensing would greatly help reduce the incidence of potentially inappropriate medication use among elderly patients.

Prevalence, knowledge and perception of self-medication practice among undergraduate healthcare students.

BACKGROUND: Globally, self-medication is a common practice, and an increasingly perceived necessity to relieve burdens on health services. However, inappropriate self-medication may result to reduced health outcomes, increased antimicrobial resistance and economic waste. Healthcare students are the future health professionals who will be consistently responsible for educating the public on rational use of medication. This study therefore aimed to assess the prevalence, knowledge and perception of self-medication practices among healthcare students. METHODS: A cross-sectional study was carried out among 866 healthcare students in a Nigerian University, comprising medical, nursing and pharmacy students. Information was garnered from respondents using a self-administered questionnaire. Data were summarized with descriptive statistics, while Chi-square and logistic regression tests were used for categorical variables at p < 0.05. RESULTS: Mean age was 21 ± 2.8 years, and female respondents were 447 (51.6%). Prevalence of self-medication among respondents was 473 (54.6%). A total of 288 (55.3%) demonstrated good knowledge of self-medication practices, comprising 250 (52.2%) among those who have previously self-medicated and 229 (47.8%) among those who had not. Reasons for engaging in self-medication practices were mentioned to include treatment of minor ailments (357; 32.4%), while 248 (22.5%) believed they had the medical knowledge of what to use. Analgesic (353; 30.1%), antimalarial (352; 30.0%), and antibiotics (182; 15.5%) were the commonest classes of medication used for self-medication. Headache (363; 18.4%), malaria (334; 16.9%), and cough (184; 9.3%) were the most frequently treated conditions. More than half (281; 59.4%) of the respondents' purchased their self-medicated drugs from the community pharmacy. Gender and respondents' disciplines were found to be the independent predictors for good knowledge of self-medication practice. CONCLUSION: Prevalence of self-medication among the studied healthcare students is moderately high, while approximately half demonstrates good knowledge and perception of self-medication practices. Stimulation for self-medication practice largely arise from the perception of treating minor ailments. This underscores a need for advocacy on responsible self-medication practice during the formal training of these future health professionals, in order to avert its imminent/widespread negative consequences.

Medications and the risk of falls among older people in a geriatric centre in Nigeria: a cross-sectional study.

Background Falls are a major cause of morbidity and hospitalization in older people. Many drugs have been shown to increase the risk of falls in this population. Few empirical data exist on the use of fall-risk-increasing drugs among older people of sub-Saharan Africa countries. Objective This study aimed to assess the prevalence and predictors of falls, and the association between FRIDs, drugs causing orthostatic hypotension and falls. Setting Geriatric center, University College Hospital, Ibadan, Nigeria. Methods A cross-sectional study of 400 older patients aged ≥ 60 years selected consecutively at the geriatric centre, between September and November 2019, were interviewed using a semi-structured questionnaire. Socio-demographic information, medication utilization, and history of falls were obtained. Bivariate and multivariate analyses were carried out using SPSS 23. Alpha was set at 0.05. Main outcome measure Prevalence and predictors of falls among ambulatory older patients. Results The mean age of the older patients was 72.4 ± 7.3 years and 255 (63.7%) were females. The total number of FRIDs and ODs used by older patients was 578 (35.2%). The prevalence of fall was 181 (45.3%) which was significantly higher among the females compared with the males (51.8% vs 33.8%) p = 0.01. Classes of medications such as anti-Parkinson's (p = 0.027), sedatives (p = 0.033), antipsychotics (p = 0.011) and anticholinergic (p = 0.027) were significantly associated with fall. Predictive factors for falls on logistic regression were female [OR = 2.375; 95% CI 0.274-3.704, p = 0.001] and use of antipsychotics [OR = 5.132; 95% CI 1.352-19.480, p = 0.016]. Conclusion The prevalence of falls was high and being a woman ≥ 60 years is a major risk factor for falling. Interventions to decrease falls in older patients by drug modification and deprescribing of FRIDs and ODs might reduce fall-related injuries. Thus, a multidisciplinary approach is essential for intervention to reduce the risk of falls and improve therapeutic outcomes among older patients.

When it is available, will we take it? Social media users' perception of hypothetical COVID-19 vaccine in Nigeria.

INTRODUCTION: COVID-19 pandemic is a global public health threat facing mankind. There is no specific antiviral treatment for COVID-19, and many vaccine candidates are currently under clinical trials. This study aimed to understand the perception of social media users regarding a hypothetical COVID-19 vaccine in Nigeria. METHODS: we conducted a cross-sectional survey among social media users in Nigeria in August 2020 using an online questionnaire. The questionnaire includes sections on the demographic characteristics of the respondents and their perception regarding a hypothetical COVID-19 vaccine. A total of 517 respondents completed and returned the informed consent along with the questionnaire electronically. Data were coded and abstracted into Microsoft Excel spreadsheet and loaded into the STATA 14 software for final analysis. RESULTS: the results showed that more than half of the respondents were male 294 (56.9%). Most of the respondents 385 (74.5%) intend to take the COVID-19 vaccine when it becomes available. Among the 132 respondents that would not take the COVID-19 vaccine, the major reason for non-acceptance was unreliability of the clinical trials 49 (37.1%), followed by the belief that their immune system is sufficient to combat the virus 36 (27.3%). We found a significant association between the age of the respondents and the COVID-19 vaccine acceptance (P-value=0.00) as well as geographical location and COVID-19 vaccine acceptance (P-value=0.02). CONCLUSION: it was observed that most of the respondents were willing to take the COVID-19 vaccine. Our findings also reiterate the need to reassure the public the benefits an effective and safe COVID-19 vaccine can reap for public health. There is a need for national health authorities in Nigeria to ensure public trust is earned and all communities, including the marginalized populations, are properly engaged to ensure an optimal COVID-19 vaccine acceptance.

The impact of COVID-19 pandemic on medicine security in Africa: Nigeria as a case study.

COVID-19 is an unprecedented pandemic posing major threat to global public health. In the past decades of years or so, one could have heard of how dangerous it is to be virtually reliant on medicine supply from other countries. Nonetheless, no action was taken because it seemed to many that the global trade system was operational and Nigerians as well as citizens of African countries appear to have sufficient supply of the medications required at quite appealing cost. Currently in 2020, this apprehension has revolved from an imaginary problem to an actual challenge that might have consequences for millions nationwide due to COVID-19 pandemic. Now, African countries can realize that putting all our eggs in one basket was not such a good idea. In Nigeria, over 70% of the prescribed medications are produced from active ingredients (API) primarily sourced from firms in China and India. Access to medicine is an integral part of healthcare systems, uninterrupted access to medicine is much needed and essential for the well-being of the population. We are now approaching the conclusion that it is more reasonable to probably invest a little more to resuscitate a domestic pharmaceutical synthesis and herbal medicine research capacity in Nigeria and across African countries to improve public health.

Evaluation of prescription pattern of analgesic use among ambulatory elderly in South-Western Nigeria.

Background: Inappropriate prescribing of analgesics has a global impact on the health of elderly patients and the society. Empirical evidence on the prescription of analgesics among elderly Nigerians is scarce. Objectives: The objective of the study was to evaluate the prescription pattern of analgesics and describe the co-prescribing of gastroprotective agents with non-steroidal anti-inflammatory drugs (NSAIDs) among elderly patients at the geriatric center, University College Hospital, Ibadan. Methods: A retrospective cross-sectional, hospital-based study was carried out among elderly patients (≥60 years) who were prescribed analgesics. Using a data extraction sheet, information on demographic characteristics, drug utilization pattern, and morbidities was obtained from patients' case files via electronic health records. Results: A total of 337 patients case files were reviewed, the mean age was 72 ± 8.8 years, and 210 (62.3%) were females. There were a total of 2074 medications prescribed, with 733 (35.3%) being analgesics. Majority of the elderly patients (259, 76.9%) were on nonopioids, with 252 (74.8%) on NSAIDs. Paracetamol was the most commonly prescribed analgesics (181, 24.6%), followed by diclofenac/misoprostol (177, 24.1%), opioid analgesic prescribed was 88 (12.0%), with paracetamol/codeine 58 (65.9%), and tramadol 16 (18.2%) being the most prescribed opioid. A significant proportion of the hypertensive elderly patients (160, 78.8%; P < 0.036) were on NSAIDs. The oral route of administration (302, 89.6%) was the most common route of administration. Majority (310, 92%) of elderly patients taking NSAIDs had a co-prescription for gastroprotective agents. Conclusions: Majority of hypertensive patients were on NSAIDs. This calls for prompt awareness of rational analgesic use among the elderly to improve management and their survival.

RésuméContexte: La prescription inappropriée d'analgésiques a un impact mondial sur la santé des patients âgés et la société. Les preuves empiriques sur la prescription d'analgésiques chez les Nigérians âgés sont rares. Objectifs: L'objectif de l'étude était d'évaluer le schéma de prescription des analgésiques et de décrire la co-prescription d'agents gastroprotecteurs avec des anti-inflammatoires non stéroïdiens (AINS) chez les patients âgés du centre gériatrique, University College Hospital, Ibadan. Méthodes: Une étude rétrospective transversale en milieu hospitalier a été menée auprès de patients âgés (≥ 60 ans) à qui l'on avait prescrit des analgésiques. À l'aide d'une feuille d'extraction de données, des informations sur les caractéristiques démographiques, le mode d'utilisation des médicaments et les morbidités ont été obtenues à partir des dossiers des patients via les dossiers de santé électroniques. Résultats: Un total de 337 dossiers de patients ont été examinés, l'âge moyen était de 72 ± 8,8 ans et 210 (62,3%) étaient des femmes. Au total, 2074 médicaments ont été prescrits, dont 733 (35,3%) étaient des analgésiques. La majorité des patients âgés (259, 76,9%) étaient sous nonopioïdes, avec 252 (74,8%) sous AINS. Le paracétamol était l'analgésique le plus couramment prescrit (181, 24,6%), suivi du diclofénac / misoprostol (177, 24,1%), l'analgésique opioïde prescrit était de 88 (12,0%), avec le paracétamol / codéine 58 (65,9%) et le tramadol 16 (18,2%) étant l'opioïde le plus prescrit. Une proportion importante des patients âgés hypertendus (160, 78,8%; P <0,036) étaient sous AINS. La voie d'administration orale (302, 89,6%) était la voie d'administration la plus courante. La majorité (310, 92%) des patients âgés prenant des AINS avaient une co-prescription d'agents gastroprotecteurs. Conclusions: La majorité des patients hypertendus étaient sous AINS. Cela nécessite une prise de conscience rapide de l'utilisation rationnelle des analgésiques chez les personnes âgées pour améliorer la prise en charge et leur survie.

Potentially inappropriate medication use among older patients attending a geriatric centre in south-west Nigeria.

OBJECTIVES: To determine the prevalence and describe factors associated with the use of potentially inappropriate medication (PIM) among older patients. METHODS: Cross sectional study of 400 older patients selected systematically at the geriatric centre, University College Hospital, Ibadan between July and September 2016. With the aid of semi-structured questionnaires, information on the socio-demographic characteristics, lifestyle habits, healthcare utilisation and morbidities was obtained. The Beer's criteria 2015 update was used to identify the PIMs. Predictors of PIMs were determined using multivariate analyses at alpha 0.05. RESULTS: Age was 70.2 (SD=5.9) years and 240 (60%) were females. General prescription pattern showed antihypertensives (34.7%) as the commonest medications used. The point prevalence of PIMs use was 31%. In all, 10 PIMs were used by the respondents. The majority (81.5%) were using one PIM, while (17.7%) used two PIMs and (0.8%) 3 PIMs. NSAIDs (72.6%) were the commonest PIMs identified, followed by the benzodiazepines (24.2%). Respondents had an average of 1.9 morbidities, and mulitmorbidity found in 60.5%. Logistic regression analysis showed self-rated health assessed as better compared with age-mates [OR =1.718 (1.080-2.725)] and being physically active [OR =1.879 (1.026-3.436)] as the most significantly associated with PIMs use. CONCLUSIONS: The use of PIMs among older patients in our setting was high with NSAIDs being the most frequently used medications. An interdisciplinary approach, of medication review by pharmacists', working with physicians may improve prescribing practices among older persons. Therefore, it is necessary to create public health awareness on the use of PIMs among older persons.
