Item Development and validation of a questionnaire to assess the doctors and nurses knowledge of acute oxygen therapy(PLoS ONE, 2019-02-04) Desalu, Olufemi; Aladesanmi, Adeniyi; Ojuawo, Olutobi; Opeyemi, Christopher; Ibraheem, Rasheedah; Suleiman, Zakari; Oyedepo, Olanrewaju; Adesina, Kikelomo; Oloyede, Taofeek; Sanya, EmmanuelBackground: Prescription and administration of oxygen in emergencies by healthcare providers are reported to be inappropriate in most settings. There is a huge gap in the knowledge of health care providers on various aspects of oxygen therapy, and this may be a barrier to optimal oxygen administration. Hence, it is essential to ascertain providers’ knowledge of acute oxygen therapy so that appropriate educational interventions are instituted for better delivery. There is no available validated instrument to assess knowledge of acute oxygen therapy. The study aimed to develop, validate and evaluate the test-retest reliability of a questionnaire to determine the doctors and nurses understanding of acute oxygen therapy. Methods: This study involved the development of the questionnaire contents by a literature review, assessment of face validity (n = 5), content validity, using a panel of experts (n = 10), item analysis and test-retest reliability among a sample (n = 121) of doctors and nurses. Results: Face validity indicated that the questionnaire was quick to complete (10–15 min), most items were easy to follow and comprehensible. The global content validity index (S-CVI) was 0.85. The test-retest reliability statistics showed a kappa coefficient of 0.546–0.897 (all P<0.001) and percentage agreement of 80–98.3% indicating high temporal stability in the target population. In total, 90% of the items fulfilled the reliability acceptance criteria. Item discrimination analysis showed that most questions were at an acceptable level. The final questionnaire included 37 item questions and eight sections. Conclusion: The designed questionnaire is a reliable and valid tool for assessing knowledge of acute oxygen therapy among doctors and nurses.Item Physicians' prescribing pattern, perceived safety of asthma medications and management of asthma during pregnancy in Nigeria(Wolters Kluwer - Medknow, 2015) Desalu, Olufemi; Adesina, Kikelomo; Adeoti, Adekunle; Fadare, Joseph; Sanya, Emmanuel; Shorunmu, Teslim; Okere, RaymondBackground: Under‑treatment of asthma in pregnancy can result in adverse fetal and maternal outcomes. The potential risk of teratogenicity may limit prompt and adequate management of medical disorders in pregnancy. Objectives: The objective of this study was to investigate the physicians’ prescribing pattern, their perceived safety of asthma medications and management of asthma during pregnancy in obstetric care units of a developing country. Materials and Methods: A self‑administered questionnaire containing case vignettes and multiple choice questions were used to evaluate the physicians prescribing practices, their perceived safety of medications and approach to asthma management in pregnancy. Result: Of the 144 doctors that participated in the study; 76 (52.8%) would prefer inhaled long‑acting β2 agonist and inhaled corticosteroids combination (LABA/ICSs) while 10 (6.9%) would prefer leukotriene antagonists (LTA) as a controller medication in the first trimester of pregnancy. Short‑acting β2 agonists, LABA, and theophylline were perceived to be safest throughout pregnancy, corticosteroids and cromoglycates were considered unsafe in first trimester while LTA were considered unsafe in all the trimesters by a majority of respondents. To gain asthma control in a patient already on low dose LABA/ICS, 94 (65.3%) of the doctors would refer their to a respiratory specialist instead of increasing the dose of LABA/ICS. Less than half (42.3%) were willing to address medication compliance in nonconforming patients. The majority (72.2%) of the doctors’ self‑reported nonadherence to the asthma treatment guideline. Conclusion: Even though, most of the physicians caring for pregnant women seem to prefer LABA/ICS combination for asthma control, there exist a knowledge gap in the stepwise management of asthma, perceived safety of most asthma medications and tackling poor medication adherence.Item Prevalence of asthma and respiratory symptoms during pregnancy in the middle belt of Nigeria.(Taylor & Francis Group`123456789]\-563z, 2019) Desalu, Olufemi; Adesina, Kikelomo; Ojuawo, Olutobi; Ogunlaja, Idowu; Alaofin, Wemimo; Aladesanmi, Adeniyi; Opeyemi, Christopher; Oguntoye, Micheal; Salami, AlakijaBackground: Information about the burden of asthma during pregnancy in Africa is scarce. Objectives: To determine the prevalence of asthma and respiratory symptoms in pregnancy in Ilorin, Nigeria. Methods: This study uses the European Community Respiratory Health Survey (ECRHS) questionnaire and definitions to screen 870 pregnant women attending three hospitals for asthma. Results: The prevalence of possible asthma (i.e. awakened by shortness of breath, asthma attack(s) in the last 12 months, or currently taking asthma medication) was 2.1% (95% CI: 1.3–3.1%), physician-diagnosed asthma was 1.0% (95% CI: 0.5–1.7%), and current asthma (asthma attack in the last 12 months and currently taking asthma medication) was 0.7% (95% CI: 0.2–1.3%). The prevalence of respiratory symptoms ranged from 0.6% (95% CI: 0.1–1.1%) for wheezing without cold to 12.9% (95% CI: 10.7–15.2%) for nasal allergies. Less than 1% reported an asthma attack and using asthma medication in the last 12 months. None of the pregnant women smoked tobacco during pregnancy. Pregnant women with possible asthma experienced more respiratory symptoms and worsening symptoms than those without asthma (15.8% vs. 3.9%), and the most reported symptom was being awakened by shortness of breath. The majority (55.6%) with physician-diagnosed asthma had suffered an asthma attack in the current pregnancy with a median of two attacks. Conclusion: The prevalence of asthma and respiratory symptoms in pregnancy in this sample was low, but we observed an increase and worsening of respiratory symptoms during pregnancy in those with asthma. Hence, the priority of clinicians should be disease control to prevent feto-maternal morbidity and mortality.
