Admission profile and management of community acquired pneumonia in Nigeria-5 year experience in a tertiary hospital

SummaryBackgroundStudies examining the prevalence, baseline characteristics and outcome of patients admitted with Community Acquired Pneumonia (CAP) are not readily available in Nigeria. This study aims to evaluate the management of CAP at a tertiary hospital in Nigeria with a view to determining the prevalence, characteristics, severity and outcome of the admitted patients.MethodsWe retrospectively collected data from 160 admitted patients with final diagnosis of CAP who met the inclusion criteria. Data relating to their age, gender, clinical details, severity assessment using CURB65 score, laboratory results, initial antibiotics prescribed, and outcome (length of stay, hospital mortality) were collected. Descriptive statistics of demographic and clinical variables were calculated and presented as frequencies, percentage, means, standard deviation and range.ResultsCAP accounted for 2.5% of all medical admissions during the study period. The mean age of the admitted patients was 52.9 ± 18.98 years with about 35% of the patients being at least 65years and above. Sputum culture, Fasting blood sugar and HIV screening were requested for in 49(30.6%), 50(31.3%) 56(35%) patients respectively. None of the patients had severity score documented on admission and only 32(20%) patients had severity score of ≥3 when calculated. Commonly prescribed antibiotics were a combination of intravenous ceftriaxone and metronidazole. Hospital mortality rate was 11.9%ConclusionWe suggest multicenter prospective studies to determine the prevalence and burden of CAP in Nigeria. There is need for an improved assessment and appropriate use of guidelines in the management of patients presenting with CAP

Examining catastrophic costs and benefit incidence of subsidized antiretroviral treatment (ART) programme in south-east Nigeria.

OBJECTIVES: To examine the extent to which costs of subsidized antiretrovirals treatment (ART) programmes are catastrophic and the benefit incidence that accrues to different population groups. METHODS: Data on expenditures to patients for receiving treatment from a government subsidized ART clinic was collected using a questionnaire. The patient costs excluded time and other indirect costs. Catastrophic cost was determined as the percentage of total expenditure on ART treatment as a proportion of household non-food expenditures on essential items. RESULTS: On average, patients spent 990 Naira (US$8.3) on antiretroviral (ARV) drugs per month. They also spent an average of$8.2 on other drugs per month. However, people that bought ARV drugs from elsewhere other than the ART clinic spent an average of $88.8 per month. Patients spent an average of$95.1 on laboratory tests per month. Subsidized ARV drugs depleted 9.8% of total household expenditure, other drugs (e.g. for opportunistic infections) depleted 9.7%, ARV drugs from elsewhere depleted 105%, investigations depleted 112.9% and total expenditure depleted 243.2%. The level of catastrophe was generally more with females, rural dwellers and most poor patients. Females and urbanites had more benefit incidence than males and rural dwellers. CONCLUSION: Subsidized ART programme lowers the cost of ARV drugs but other major costs are still incurred, which make the overall cost of accessing and consuming ART treatment to be excessive and catastrophic. The costs of laboratory tests and other drugs should be subsidized and there should also be targeting of ART programme to ensure that more rural dwellers and the most-poor people have increased benefit incidence

Bronchoscopy in Nigerian Clinical Practice: A Survey of Medical Doctors’ Perception, Use and Associated Challenges

BACKGROUND: Bronchoscopy is a vital diagnostic and therapeutic procedure in pulmonological practice. The aim of this study was to determine the perception, use and challenges encountered by Nigerian medical doctors involved in this procedure.MATERIALS AND METHODS: A cross-sectional study was conducted among 250 medical doctors recruited from three major tertiary institutions in Nigeria between September 2013 and June 2014. A semi-structured questionnaire was self-administered to adult physicians, paediatricians, and surgeons as well as their trainees to obtain their perception, use and associated challenges in the use of bronchoscopy in clinical practice.RESULTS: The majority (91.6%) of the respondents perceived bronchoscopy as a beneficial procedure to respiratory medicine. However, 59.2% of them were not aware of the low mortality rate associated with this procedure. The commonest indications for bronchoscopic use were foreign body aspiration (88.8%) and management of lung tumors (75.6%). Only 21 (8.4%) of the respondents had received formal training in bronchoscopy. Very few procedures (1-5 cases per month) were performed. The respondents identified the lack of formal training in the art of bronchoscopy as the foremost challenge facing its practice in Nigeria. In addition, availability of bronchoscopes, level of awareness, knowledge of the procedure among medical doctors and the cost of the procedure were the challenges faced by the medical doctors.CONCLUSION: There is an urgent need to equip training centers with modern bronchoscopic facilities. In addition,well-structured bronchoscopic training programme is imperative to enhance the trainees’ proficiency for the furtherance of bronchoscopic practice.KEYWORDS: Bronchoscopy, Nigeria, Respiratory medicine, Interventional pulmonology, Trainin

Knowledge and use of asthma control measurement tools in the management of asthma: a survey of doctors working in family and internal medicine practice in Nigeria.

Objective: To investigate the knowledge and use of asthma control measurement (ACM) tools in the management of asthma among doctors working in family and internal medicine practice in Nigeria. Method: A questionnaire based on the global initiative on asthma (GINA) guideline was self-administered by 194 doctors. It contains 12 test items on knowledge of ACM tools and its application. The knowledge score was obtained by adding the correct answers and classified as good if the score 65 9, satisfactory if score was 6-8 and poor if < 6. Results: The overall doctors knowledge score of ACM tools was 4.49\ub12.14 (maximum of 12). Pulmonologists recorded the highest knowledge score of 10.75\ub11.85. The majority (69.6%) had poor knowledge score of ACM tools. Fifty (25.8%) assessed their patients\u2019 level of asthma control and 34(17.5%) at every visit. Thirty-nine (20.1%) used ACM tools in their consultation, 29 (15.0%) of them used GINA defined control while 10 (5.2 %) used asthma control test (ACT). The use of the tools was associated with pulmonologists, having attended CME within six months and graduated within five years prior to the survey. Conclusion: The results highlight the poor knowledge and use of ACM tools and the need to address the knowledge gap

Identifying patients at high risk for obstructive sleep apnoea syndrome in Nigeria: A multicentre observational study

Background: Obstructive sleep apnoea is associated with significant health consequences. A significant proportion of hospitalized patients at risk for obstructive sleep apnoea were never identified and referred for polysomnography for diagnosis. The objective of this study was to determine the factors associated with high risk for obstructive sleep apnoea and use it to identify patients at risk for the condition in tertiary hospitals in Nigeria.Methods: This was a multicentre observational study of adult patients hospitalized in three selected hospitals from 15th January to 17th March 2015. Berlin questionnaire and Epworth sleepiness scale were used to assess for obstructive sleep apnoea risk and excessive daytime sleepiness respectively. Additional questions on traditional risk factors for obstructive sleep apnoea were also obtained.Results: Nine hundred and twenty-six patients were recruited into the study. Respondents’ mean age was 44.3 years ± 15.2years, 486 (52.5%) were females and 556 (60.0%) had one or more medical co-morbidity and none of the patients had a previous diagnosis of obstructive sleep apnoea. Factors that were independently associated with high risk for obstructive sleep apnoea include systemic hypertension(aOR-10.33;95%: CI 6.42-16.61), obesity(aOR-7.87;95% CI: 4.33-14.29); excessive daytime sleepiness (aOR-3.77;95% CI:2.28-6.22), tobacco smoking (aOR-2.99;95% CI: 1.76-5.07), snoring in a first-degree relative (aOR-1.83;95% CI: 1.19-2.81); and the use of sedative (aOR-1.82;95% CI: 1.06-3.15).Conclusions: This study shows that patients with systemic hypertension, obesity, excessive daytime sleepiness, history of smoking, snoring in a firstdegree relative and use of sedatives are at high risk of obstructive sleep apnoea. None of the patients at high risk had a previous diagnosis of sleep apnoea by a physician, highlighting the diagnostic challenges of this condition. The results of this study will assist health care professionals in early identification of individuals at risk of obstructive sleep apnoea and subsequent referral for a sleep study

Prevalence, awareness and reporting of symptoms of obstructive sleep apnoea among hospitalized adult patients in Nigeria: A multicenter study

Background: Obstructive sleep apnoea is the most common form of sleep- disordered breathing in adults and children. It is associated with many adverse  health consequences. The objectives this study were to determine the prevalence, awareness and reporting of symptoms of obstructive sleep apnoea among  hospitalized adult patients in Nigeria.Methods: This was a multicenter cross-sectional study involving 1420 adult patients admitted to general medical and surgical wards of selected hospitals from March to April 2013. A questionnaire embedded with Berlin questionnaire, Epworth sleepiness scale and questions on level of awareness and reporting of symptoms of sleep apnoea was used for data collection.Results: One-third of the patients (33.4%) reported snoring, 16.3% had excessive daytime sleepiness, 10.0% experienced daytime fatigue, and 8.0% experienced  drowsy driving. Approximately 5% reported witnessed apnoea and 18.0% had high risks for obstructive sleep apnoea. The frequency of high risk for sleep apnoea  increased with age and declined after 65 years and also increased with the body  mass index. Snoring, excessive daytime sleepiness and high risk for obstructive  sleep apnoea were more common in patients with chronic medical conditions and  who were admitted to the urban hospitals. The majority were not aware that snoring (77.3%) and excessive daytime sleepiness (65.8%) constitute a medical problem, and only 4.5% reported these symptoms to their doctors.Conclusions: The level of awareness and under-reporting of sleep apnoea symptoms are poor. The high prevalence of obstructive sleep apnoea symptoms from this study should form the basis for screening hospitalized patients with chronic medical condition across the country.Keywords: Obstructive sleep apnoea, Nigeria, Snoring, Prevalence, Awareness, Under-reportin

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

<p>Abstract</p> <p>Background</p> <p>Spirometry 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.</p> <p>Methods</p> <p>We 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.</p> <p>Results</p> <p>Of 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%).</p> <p>Conclusion</p> <p>The 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.</p

Prevalence of drug-resistant tuberculosis in Nigeria: A systematic review and meta-analysis

<div><p>Background</p><p>Drug-resistant tuberculosis (TB) undermines control efforts and its burden is poorly understood in resource-limited settings. We performed a systematic review and meta-analysis to provide an up-to-date summary of the extent of drug-resistant TB in Nigeria.</p><p>Methods</p><p>We searched PubMed, Scopus, Embase, HINARI, AJOL, the Cochrane library, Web of Science, and Google Scholar for reports published before January 31 2017, that included any resistance, mono-resistance or multidrug resistance to anti-TB drugs in Nigeria. Summary estimates were calculated using random effects models.</p><p>Results</p><p>We identified 34 anti-TB drug resistance surveys with 8002 adult TB patients consisting of 2982 new and 5020 previously-treated cases. The prevalence rate of any drug resistance among new TB cases was 32.0% (95% CI 24.0–40.0%; 734/2892) and among previously-treated cases, the rate was 53.0% (95% CI 35.0–71.0%; 1467/5020). Furthermore, multidrug resistance among new and previously-treated cases was 6.0% (95% CI 4.0–8.0%;161/2502)and 32.0% (95%CI 20.0–44.0; 357/949), respectively. There was significant heterogeneity between the studies (p<0.001, I² tests). The prevalence of drug-resistant TB varied according to methods of drug susceptibility testing and geographic region of Nigeria.</p><p>Conclusion</p><p>The burden of drug-resistant TB in Nigeria is high. We recommend that a national anti-TB drug resistance survey be carried out, and strategies for case detection and programmatic management of drug-resistant TB in Nigeria need to be strengthened.</p></div
