ABSTRACT
BACKGROUND: Training nursing students on quality and patient safety (PS) is crucial to ensuring safe healthcare practices given the key role nurses play on the healthcare team. The aim of this study was to evaluate the impact of quality and PS course on the knowledge, and system thinking of students at different stages of the undergraduate nursing course. METHODS: A 4.5-day quality improvement and PS course was conducted at the Aga Khan University School of Nursing and Midwifery for 146 second- and 139 fourth-year students. Students' knowledge, self-assessment of knowledge and skills, and system thinking were assessed using pretest and posttest. RESULTS: Of the total of 20 points, the course significantly improved students' knowledge by a mean of 4.91 points for second-year students (95% confidence interval [CI], 4.32-5.51) and 3.46 points for fourth-year students (95% CI, 2.90-4.02) between pretest and posttest. For systems thinking, the Systems Thinking Scale scores increased by 0.41 points (95% CI, 0.29-0.52) for second-year students and 0.33 points (95% CI, 0.22-0.44) for fourth-year students out of the total of 5 points. The self-assessment scores significantly increased on postcourse assessment for second (P < 0.05) and fourth-year students (P < 0.001). Positive experience reported by students in the narrative reflections complemented these results. CONCLUSIONS: There was a significant increase in nursing students' knowledge, self-efficacy, and system thinking after participating in this short PS course. Replication at a national level may improve safety knowledge and skills among nursing students with subsequent gains in the safety of healthcare delivery in Pakistan.

Objectives: To evaluate the feasibility of a novel and simple smart phone-based Retinopathy of Prematurity (ROP) screening approach in a resource-constrained setting. Methods: This cross-sectional validation study was conducted at the Department of Ophthalmology and Neonatal Intensive Care Unit (NICU) of The Aga Khan University Hospital, Pakistan, from January 2022 to April 2022. A total of 63 images of eyes with active ROP (stage-1, 2, 3, 4 and/or plus or pre-plus disease) were included in this study. The stage of ROP was documented by the principal investigator using an indirect ophthalmoscope and retinal images were obtained using this novel technique. These images were shared with two masked ROP experts who rated the image quality and determined the stage of ROP and presence of plus disease. Their reports were compared with the initial findings reported by principal investigator using indirect ophthalmoscope. Results: We reviewed 63 images for image quality, stage of ROP and presence of plus disease. There was significant agreement between the gold standard and the Rater-1 and 2 for the presence of plus disease (Cohen's kappa was 0.84 and 1.0) and the stage of the disease (Cohen's kappa 0.65 and 1.0). There was significant agreement between the Rater for presence of plus disease and any stage of ROP (Cohen's κ: 0.84 and 0.65 for plus disease and any stage of the ROP, respectively). Rater-1 and 2 rated 96.83% and 98.41% images as excellent / acceptable respectively. Conclusions: High quality retinal images can be captured with a smartphone and 28D lens without using any additional adapter equipment. This approach of ROP screening can form basis of telemedicine for ROP in resource constrained areas.
ABSTRACT
AIM: To evaluate the recently described optical coherence tomography (OCT) based classification of epiretinal membrane (ERM) and its usefulness in predicting the functional outcome. METHODS: A retrospective observational review of OCT scans of patients with the diagnosis of idiopathic ERM was carried out from January 2016 to June 2021. All consecutive images diagnosed with any stage of idiopathic ERM and fulfilled the eligibility criteria were included in the analysis. ERM was identified on OCT scans as a thin hyperreflective layer over the inner layers of retina. OCT scans of patients with ERM who underwent vitrectomy, were independently staged as per the new classification by two independent retinal surgeons to form a consensus on stage. Best corrected visual acuity (BCVA) in logMAR scale and central subfield thickness (CST) on pre- and post-operative spectral domain OCT scans were the variables noted for all patients at the time of diagnosis and at 6 and 12mo follow up visit after undergoing intervention. Partial correlation coefficient was computed between BCVA (logMAR) and CST by ERM stage adjusting by baseline measures. RESULTS: Clinical charts of 74 patients with idiopathic ERM were assessed. Clinically significant improvement in BCVA overtime was observed with significant difference in median visual acuity of patients with Stage II-IV ERM with P<0.001. The median CST of all patients with stage II-IV ERM showed similar consistent improvement with P<0.001 from baseline to 12th month. Our results showed not only gain in visual acuity but also shift from baseline to anatomical normalization of CST in stage II. We found a decrease in CST with difference of 166 µm and 151 µm in stage III and stage IV respectively. Our results remained consistent with the hypothesis of improved visual outcomes with all stages of ERM with adjusted moderate linear correlation between visual acuity and CST in stage II-IV (r>0.3). CONCLUSION: Equally significant visual outcomes of patients with ERM staged II-IV and therefore can be counselled for improved visual acuity after surgical removal of ERM with improvement up to 5 lines on Snellen's chart from the baseline.
ABSTRACT
A female patient in early 50s presented to us several months after developing severe visual loss in her right eye. The patient was diagnosed with resolved central retinal vein occlusion (CRVO) based on the clinical picture at the time of presentation, however, retroactive evaluation of fundus imaging and further multi-disciplinary workup led to the rare diagnosis of combined central retinal artery and vein occlusion associated with antiphospholipid syndrome (APS). Only a few cases reporting retinal arterial and venous occlusions in patients with APS are found in the literature. To the best of our knowledge, no case of simultaneous CRAO and CRVO has been reported with APS. The patient was started on lifelong warfarin therapy to prevent a similar episode in the left eye. It is important to properly evaluate patients presenting with retinal vascular occlusions, as a missed diagnosis of APS can lead to recurrent and more devastating vascular events.
