Background: Advanced posttraumatic osteoarthritis (PTOA) of the knee is a cause of substantial disability, particularly in younger individuals, and the treatment of choice is total knee arthroplasty (TKA). Racial and socioeconomic disparities exist in the use of TKA, but, to our knowledge, there have been no studies examining these disparities among patients with PTOA. Methods: We performed chi-square and logistic regression analyses on data from the Nationwide Inpatient Sample (NIS). The outcome of interest was the rate of TKA utilization, and the primary predictors were racial/ethnic group and insurance status. The regression models were adjusted for age, sex, household income, and Charlson Comorbidity Index (CCI). Results: The odds of receiving TKA for Black patients (odds ratio [OR] = 0.55; 95% confidence interval [CI], 0.48 to 0.62) and Hispanic patients (OR = 0.53; 95% CI, 0.46 to 0.62) were lower compared with White patients. Patients with Medicare (OR = 0.51; 95% CI, 0.46 to 0.57), those with Medicaid (OR = 0.48; 95% CI, 0.42 to 0.55), and those who self-paid (OR = 0.91, 95% CI: 0.14 to 0.25) had significantly lower odds of TKA compared with those with private insurance. Conclusions: Black and Hispanic patients are less likely than White patients to utilize TKA, and patients with private insurance are more likely to utilize TKA. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Aim: This study aimed to compare the effect of spinal anesthesia on QT interval in severe pre-eclamptic and normotensive parturients who underwent cesarean section in a Nigerian tertiary hospital. Patients and Methods: Twelve-lead electrocardiogram (ECG) was obtained before, and at intervals after spinal anaesthesia on fifty severe pre-eclamptic (Group A) and fifty normotensive parturients (Group B) who underwent caesarean section. The effect of spinal anaesthesia on QT interval was compared. Results: The preoperative (baseline) mean QT interval was longer in group A than in group B; 453.10 ± 34.11 ms versus 399 ± 18.79 ms, P < 0.001. The prevalence of prolonged QT interval in the severe pre-eclamptic group before spinal anesthesia was 80% while in the normotensive group it was 0%, P < 0.001. At 5, 30, 60, and 120 min after the establishment of spinal anesthesia, the mean QT interval in the severe pre-eclamptic group was shortened and maintained within normal limits; 414.74 ± 28.05, 418.28 ± 30.95, 411.18 ± 19.21 and 401.36 ± 17.52 ms with P < 0.001 throughout. In the normotensive group, there was no significant change in the mean QT interval. Conclusions: This study demonstrated that the QT interval was more prolonged among the severe pre-eclamptic parturients. Spinal anesthesia using 0.5% hyperbaric bupivacaine normalized the QT interval and maintained it within normal limits during the study period.

Purpose Oxygen may cause serious consequences when administered wrongly. This study aimed to assess doctors’ and nurses’ knowledge of acute oxygen therapy and perceived delivery barriers. Participants and Methods We conducted a cross sectional study among 202 healthcare providers (134 doctors and 68 nurses) in a Nigerian hospital. The validated Acute Oxygen Therapy Questionnaire (AOTQ), which consisted of 21 knowledge assessment questions, was self administered by participants. Provider’s knowledge was classified as good if the score was≥80% and poor if < 60%. Results Overall, 26.7% (37.3% doctors and 5.9% nurses) had good knowledge of acute oxygen therapy (AOT), 35.9% were aware, and 19.3% used the AOT guidelines. The commonest source of knowledge on oxygen therapy was medical /nursing school (75.2%). The participants’ mean knowledge score was 14.75 ± 2.83(possible score of 0–21). Doctors in postgraduate (PG) training obtained the highest score (15.96±2.48) among the participants (F=12.45, df=4, p<0.001). Most doctors (62%) and 23.5% of nurses considered oxygen as a drug. More doctors (52.2%) than nurses (14.7%) believed that a doctor’s order was mandatory before oxygen administration, contrary to guidelines recommendations. Most nurses did not know that breathlessness does not always signify hypoxemia and that asymptomatic anemia was not an indication for oxygen. Concerning oxygen prescription, 39.7% of nurses and 64.2% of doctors knew that it should be prescribed to achieve a target saturation range rather than a fixed dose. In acute oxygen delivery in COPD, doctors and nurses exhibited poor knowledge of the appropriate device and flow rate. The reported barriers to oxygen delivery were: a shortage of oxygen supply, inadequate delivery devices, power outages and out of pocket costs. Conclusion A significant proportion of doctors and nurses had poor knowledge of acute oxygen therapy, poor awareness and infrequently used AOT guidelines, and reported pertinent delivery barriers that warrant educational and administrative interventions.

Background 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.

Background: Lumbosacral radicular pain is a common cause of chronic low back pain. Despite published reports of effectiveness of transforaminal epidural steroid for lumbosacral radicular pain, it is underutilised in many tertiary hospitals in sub-Saharan Africa. This study assessed the clinical effects of transforaminal epidural steroid injections in patients with lumbosacral radicular pain at a major tertiary health facility in Nigeria. Methods: This is a prospective observational study carried out between March 2012 and February 2016. Under fluoroscopy, the epidural space was accessed through the neuroforamen using 22G spinal needles in 47 adult patients with lumbosacral radicular pain; and a mixture of 10 mg triamcinolone acetonide and 0.25% plain bupivacaine (2 mLs per level) was injected. Pain intensity and functional impairment were assessed with the Numeric Pain Rating Scale (NPRS) and the Oswestry Disability Index (ODI) scores respectively at three and six months. Results: The pain and ODI scores at baseline and at six months’ follow-up improved significantly; 8.49 ± 1.28 vs. 3.6 ± 1.5 (p = 0.002) and 45.1 ± 11.5 vs. 32.4 ± 11.5 (p = 0.001) respectively. Conclusion: Transforaminal epidural steroid injections provided significant pain relief and improved function in patients with lumbar radicular pain due to intervertebral disc herniations.

OBJECTIVE Although opioid analgesics are effective in the treatment of moderate to severe acute, cancer and chronic non-malignant pains, they are under-prescribed in Nigeria. The objective of this study was to assess the prescription pattern of opioids among physicians in a north central State, Nigeria.. DESIGN This was a descriptive cross sectional study. SETTING The study was conducted at the International Association for the Study of Pain (IASP)-sponsored workshops on pain and palliative care at the University of Ilorin Teaching Hospital, Ilorin, Nigeria. PARTICIPANTS These were physicians at the monthly workshops organized by the Pain and Palliative Care Unit of the hospital between August 2011 and July, 2012. INTERVENTIONS Pre-tested semi-structured questionnaires were used to obtain responses to questions on pain management including opioids utilization in the various hospitals of the 114 participants. MAIN OUTCOME MEASURES The main outcome measure was opioid prescription by the participants. RESULTS Out of the 114 questionnaires distributed, 113 were returned with complete information giving a response rate of 99.1%. The mean age of the respondents was 42.0±10.8 years. Although 97.3% of the respondents reported that pain was a frequent complaint in their practice, 69.5% of those who reported seeing patients with moderate to severe pain on a daily basis rarely or never prescribed opioid analgesics. The reasons given for poor opioid prescription were fear of respiratory depression (86.8%), fear of addiction (85.1%) and non-availability (28.9%). CONCLUSION Opioid prescription rate for patients with moderate-severe pain is low possibly due to myths and misconceptions about their adverse effects.
