Factors influencing adherence to antiretroviral medication in Ilorin, Nigeria.

Background: Good adherence to highly active antiretroviral therapy (HAART) is required for viral suppression and prevention of drug resistance. Patients’ adherence to HAART has not been determined since the commencement of HAART at the University of Ilorin Teaching Hospital (UITH), Ilorin, Nigeria, over 5 years ago. Objectives: To determine the adherence level of people living with HIV/AIDS (PLWHA) to HAART and identify associated factors. Methodology: A semistructured questionnaire was administered to PLWHA, who were accessing treatment. Sociodemographic, lifestyle, HIV medical, and drug history were obtained from them. Adherence was self-reported. Good adherence was taking of 95% of the prescribed doses of HAART over the preceding 30 days before consultation. Results: Study participants were 253; majority, 58.5%, were females. About 70.8% of them had good adherence. Older age and male sex correlated better with adherence. Conclusion: People living with HIV/AIDS were quite adherent to HAART. Male sex and older age were positive predictors of adherence. Adherence among the young age and females needs strengthening.

Assessment of the Level of Asthma Control among Adult Patients in Two Tertiary Care Centers in Nigeria

Background. According to the Global Initiative for Asthma (GINA) guidelines, the goal of asthma management is to achieve clinical control. Uncontrolled asthma places a significant social and economic burden on patients. Objective. The two aims of this study were to (1) assess the level of asthma control (according to the GINA definition of “control”) among adult patients attending two tertiary care centers in Nigeria and (2) to determine the predictors associated with uncontrolled asthma. Methods. This cross-sectional study was carried out from June 2009 to December 2010. The participants were all 18 years old or older with physician-diagnosed asthma. First, the participants completed an interviewer-administered questionnaire, which included items that collected their socio-demographic information and clinical data. Second, anthropometric indices were measured and spirometry was conducted to determine each participant’s lung function. Finally, the researcher team members assessed each participant’s inhaler device technique. The outcome measures were (1) uncontrolled asthma, (2) partly controlled asthma, and (3) controlled asthma. Results. One hundred and twenty-four asthma patients participated in the study. Of these, 69.3% had uncontrolled asthma, 22.6% had partly controlled asthma, and 8.1% had controlled asthma. Multivariate analysis showed that uncontrolled asthma was strongly associated with asthma severity based on clinical features, the incorrect use of an inhaler device, the use of oral corticosteroids, an abnormal pulmonary function test, the presence of comorbidity, and the lack of adherence to inhaled corticosteroids (ICSs). The results also revealed that increasing age and a lack of tertiary education were weakly associated with asthma control. In this study, gender, marriage, smoking status, occupation, socioeconomic status, income, and the duration of the asthma were not associated with asthma control. Conclusion. A significant proportion of the sampled patients had uncontrolled asthma. To reduce this number, health care providers must reinforce the education of each asthma patient and promote the regular assessment of asthma control at every clinic visit, identify those with poor control, and institute the appropriate therapy needed to achieve clinical control.

Pain as a Symptom in Patients Living With HIV/AIDS Seen at the Outpatient Clinic of a Nigerian Tertiary Hospital.

Although the negative impact of pain on the quality of life of patients living with HIV has been documented in many Western studies, there is a paucity of data on pain in HIV-infected patients in Nigeria in spite of a large disease burden. We studied the frequency of pain as a symptom and determined the body regions often affected among our cohort of patients attending the antiretroviral (ARV) clinic. An interviewer-administered questionnaire was used to obtain information on presence of pain in the 2 weeks before the interview. Those with pain were further screened with the modified Brief Pain Inventory. There were 79 respondents-40.5% males, mean age 37.1 ± 8.6 years. Pain was present in 22 (27.8%) of the respondents. The major regions affected by pain were lower limbs (40.9%), head and neck (31.8%), and abdomen (31.8%). Only 40% of those with moderate to severe pain intensity reported being on any form of analgesia.Although the negative impact of pain on the quality of life of patients living with HIV has been documented in many Western studies, there is a paucity of data on pain in HIV-infected patients in Nigeria in spite of a large disease burden.

Secondhand smoke exposure among nonsmoking adults in two Nigerian cities

BACKGROUND Tobacco control policy can only succeed if the burdens of smoking are known. The objective of this study was to determine the prevalence and correlates of secondhand smoke (SHS) exposure among nonsmoking adults in two Nigerian cities. MATERIALS AND METHODS We carried out a cross-sectional study from October 2009 to April 2010 among adult population of two Nigerian cities: Enugu and Ilorin. A semi-structured questionnaire was administered by interviewers to obtain socio-demographic information; and information regarding pattern of SHS exposure, awareness of tobacco control policy and the harmful effects of SHS. SHS exposure was defined as regular exposure to tobacco smoke in the previous 30 days in a nonsmoking adult. RESULTS Of the 585 nonsmoking adults that completed the study, 38.8% had regular exposure to SHS; mostly, in public places (24.4%). More men were exposed at public places when compared with women (27.0% vs. 19.5%). The strongest factor associated with exposure to SHS in women was having a smoking spouse [prevalence rate (PR) ratio-7.76; 95% confidence interval (CI), 3.08-9.42]; and in men, it was lack of home smoking restriction (PR ratio-6.35; 95% CI, 4.51-8.93). Among men, SHS exposure at any location was associated with lack of secondary school education, residing in slum apartment (house with many households), living with a smoking family member (non-spouse), lack of home smoking restriction, and alcohol intake. Among women, SHS exposure at any location was associated with having a smoking spouse, residing in slum apartment and lack of home smoking restriction. Seventy-two percent of respondents were aware of the harmful effects of SHS on their health. Lack of awareness of the harmful effects was significantly associated with increasing age (r = +0.45; P = <0.01), lack of secondary school education (r = -0.10; P = 0.04), residing in slum apartment (r = -0.12; P = 0.03) and being a widow/widower (r = +0.24; P < 0.01). Only 17.4% of the employees reported availability of outdoor smoking area at their workplaces. CONCLUSION Our results show that prevalence of SHS exposure was the highest in public places. These findings underscore the need for enactment of comprehensive smoke-free legislation and implementation of educational strategies to reduce SHS exposure in homes.

Asthma in Nigeria: Are the facilities and resources available to support internationally endorsed standards of care?

OBJECTIVE The objective of this study was to assess the facilities and resources available to support internationally endorsed standards of asthma care at tertiary hospitals (University teaching, Federal Medical Centre and State specialist Hospitals) in Nigeria. METHODS This cross sectional study was conducted among 68 tertiary hospitals (TH) in Nigeria from June 2009 to December 2009. Structured standards of care questionnaires on asthma based on the Global initiative for asthma (GINA) guideline were completed by physician working in each of the TH. RESULTS Most TH lacked the services of respiratory physicians, internists, and pediatricians. Available basic infrastructures were asthma clinics (0%), clinic registers (20.6%), and hospital protocol (17.6%), doctors attendance of asthma CME (8.8%) and nurse educator with a bias for asthma (14.7%). Thirty eight percent of TH had peak flow meter, 29.4% had spirometer, skin allergy test kits (15.6%), pulse oximeter (38.2%) while 17.6% had arterial blood gases analyser. Nebuliser and spacer were available in 41.2% and 20.6% of TH respectively. Oral short acting beta 2 agonist (SABA) was available in 79.4% of the hospitals, glucocorticosteroid (79.4%), theophyllines (76.5%), and SABA (metered-dose inhaler MDI: 76.5%, Nebules: 35.3%). Long acting beta 2 agonist (LABA) and steroid fixed dose combination inhaler (50%) was available in 50% of TH. Glucocorticosteroid nasal spray was available in 33.3% of TH and <10% reported the availability of anti-cholinergic and chromoglycate inhaler and oral leukotriene antagonist. Standard oxygen delivery system and self-educational support materials were available in 52.9% of TH. CONCLUSION The available facilities and human resources for asthma management in Nigerian tertiary hospitals were not enough to support the standard internationally endorsed for asthma care. Provisions of deficient infrastructures and continuous training of health care personnel in asthma management are imperative to enhance the quality of care.

Evaluation of Current Knowledge, Awareness and Practice of Spirometry among Hospital -based Nigerian Doctors

BackgroundSpirometry is a cost-effective diagnostic tool for evaluation of lung function and for case-finding in a resource-limited setting. The acceptance of this test depends on the awareness of its indications and the ability to interpret the results. No studies have assessed the knowledge of spirometry among Nigerian doctors. The aim of this study was to evaluate the current knowledge, awareness and practice of spirometry among hospital-based Nigerian doctors.MethodsWe carried out a cross-sectional survey among 321 doctors working in Nigerian hospitals between March 2008 and June 2008. Information on knowledge, awareness, practice of and barriers to spirometry were obtained using a pre-tested, self-administered structured questionnaire and the data were then analysed.ResultsOf the 321 doctors that participated, 108 (33.6%) reported that they have good knowledge of spirometry. One hundred and ninety-five (60.7%) were aware of the importance of spirometry in aiding the diagnosis of respiratory diseases; 213(66.4%) were aware of the importance of spirometry in determining the severity of diseases. Medical school was the most common source of knowledge on spirometry (64.5%). Eighty-one (25.2%) doctors reported having a spirometer in their hospitals. Doctors having access to a spirometer used it more frequently for aiding the diagnosis of COPD (40.7% vs.27.5%) and for monitoring of asthma (18.5% vs.11.3%) than those without access to a spirometer. The doctors working in University Teaching Hospitals and Federal Medical Centres (FMC) (22.4% vs. 4.5%) and those having access to a spirometer (40.7 vs.11.3%) were very confident of interpreting spirometry results compared to those working in District and General Hospitals and without access to a spirometer. Irrespective of access to a spirometer or the type of hospital they were employed in, doctors reported that unavailability of a spirometer was the greatest barrier to its use (62.5%) followed by lack of awareness about its usefulness (17.2%).ConclusionThe knowledge and practice of spirometry were poor among hospital-based Nigerian doctors because of unavailability of spirometers in most hospitals. These findings have implications for further evaluation, planning and management of patient care in respiratory disease. Spirometers should be made available in all hospitals, and the knowledge of spirometry should be improved among doctors.

Awareness of the Warning Signs, Risk Factors, and Treatment for Tuberculosis among Urban Nigerians

Objectives. To determine the awareness of the warning signs, risk factors, and treatment of tuberculosis among urban Nigerians. Methods. This was a cross-sectional survey among 574 adults in Ilorin, Nigeria. Semistructured questionnaire was administered by trained interviewers to obtain information about awareness of tuberculosis warning signs, risk factors, and treatment. Results. Majority of the subjects (71.4%) were aware of at least one warning sign of tuberculosis. Cough (66.2%), weight loss (38.0%), and haemoptysis (30.7%) were the most identified warning signs. The predictors of awareness of warning sign were increasing age (r + 0.12), higher family income (r + 0.10), higher level of education (r + 0.10), and belonging to Christian faith (r + 0.11). Awareness of risk factors for tuberculosis was higher for tobacco smokers (77.0%) and history of contact with a case of TB (76.0%). Less than half were aware of HIV infection (49.8%), alcohol consumption (42.5%), chronic kidney disease (40.4%), extremes of ages (39.4%), cancers (36.9%), and diabetes mellitus (27.5%) as risk factors for TB. Tuberculosis was reported to be curable by 74.6% of the subjects and 67.9% knew that there are medications for treatment of tuberculosis, while 11.5% knew the duration of treatment. Conclusion. This study has revealed that the awareness of HIV and noncommunicable diseases as risk factors for TB is poor. This study has therefore demonstrated the need for health education programs that will emphasize recognition, identification, and modification of risk factor for TB.

An audit of spirometry at the University of Ilorin Teaching Hospital, Ilorin, Nigeria (2002-2009)

BACKGROUND Spirometry is a noninvasive and cost-effective physiologic test that greatly complements other investigative procedures in evaluation of respiratory conditions. This study was aimed at auditing the spirometry performed at the University of Ilorin Teaching Hospital (UITH) Ilorin, Nigeria, and highlighting some of the challenges associated with the procedure. METHODS We reviewed and analyzed the record of spirometry performed at the cardiopulmonary unit of the hospital from June 2002 to December 2009. RESULTS A total of 119 patients had spirometry tests from 2002 to 2009 and their age ranged from 15 to 85 years with a mean of 47.6 +/- 14.8 years. There were 69 (58%) males and the male:female ratio was 1.4:1. More than half (65%) of the tests were in patients <50 years old. The rate of spirometry performed annually increased from 12 (10.1%) in 2002 to 31 (26.1%) in year 2009. Evaluation of bronchial asthma was the most common indication for spirometry (43 patients; 36.1%). Majority of the requests (84 patients; 70.6%) were from adult respiratory physicians. The identified challenges were lack of awareness of the range of diseases that could be investigated by spirometry, lack of skills in interpreting the results, lack of time and delays in replacing exhausted consumables and faulty components of spirometer. CONCLUSION Gradually, the trend of spirometry request is increasing in UITH; however, a wider acceptability could be achieved for this test by raising the level of awareness and improving the skills of all doctors on the usefulness and interpretation of spirometry.

METODOS: Foram avaliados 498 individuos com 20-44 anos de idade em Ilorin, Nigeria, utilizando-se o questionario European Community Respiratory Health Survey (ECRHS), administrado por entrevistadores treinados. RESULTADOS: A tosse noturna apresentou associacoes com asma (OR = 10,87; p 0,05). CONCLUSOES: A prevencao precoce e o tratamento de condicoes associadas a tosse, assim como a modificacao de fatores sociais comumente associados a tosse, sao necessarios a fim de reduzir a morbidade respiratoria.

General practitioner reported follow–up visits among asthma patients in North Central Nigeria

BACKGROUND Despite the benefits of regular follow-up in the long-term care of asthma, no previous study has reported on it among asthma patients in Nigeria. OBJECTIVE This survey was designed to evaluate GP-reported follow-up visits among asthma patients in North Central Nigeria. METHODS It was a cross-sectional survey conducted among GPs in three North Central states of Nigeria. RESULTS Overall, 48.3% of the GPs reported that their patients usually come for follow-up visits. About 63.6%, 40.0%, and 55.3% of the GPs in Kwara, Kogi, and Niger states, respectively, reported that their patients came for follow-up visits in the month prior to this study. Less than two-third of GPs in both private (55.1%) and public (56.8%) hospitals reportedly attended to patients on follow-up visits. About 46.5%, 37.5%, and 52.0% of the GPs who attended to patients <1 week, 1-2 weeks and >2 weeks prior to the study reported that their patients came for follow-up visits. There was significant difference (P = 0.04) in the reported follow-up visits by GPs who attended to ≥10 asthma patients compared to others. None of the nine GPs who reportedly treated ≥ 10 patients in the preceding month of the study attended to any patient on follow-up visits. CONCLUSION The GP-reported rates of follow-up visits in patients that are accessing asthma care from GPs practicing in the North Central part of Nigeria are low. Further studies to identify barriers to follow-up visits and how to correct them are therefore recommended.
