Targeted education for clinicians and clinical coding staff improves the accuracy of clinical coding: A quality improvement project.

The allocation of healthcare resources is reliant upon accurate information generated through clinical coding. Several factors contribute to coding inaccuracies, one of which is interpreting medical documentation. A lack of awareness among medical staff of the clinical coding process and the importance of detailed documentation exacerbates this problem. To investigate this further, 1 month of inpatient clinical coding data from a single hospital ward was reviewed by clinicians experienced in the coding and auditing process. If the reviewing clinician identified inaccuracies in the initial clinical coding, Healthcare Resource Group (HRG) codes were changed. Education sessions were then provided both to junior clinicians working on the hospital ward and to clinical coding staff and a further month of clinical coding data was again reviewed to assess for any difference after the sessions. HRG changes were made in 58.5% of 94 cases initially. Following the educational sessions, 20.5% of HRGs changed in 73 cases (p<0.0001), indicating more accurate initial clinical coding. There were also statistically significant reductions in the extent to which the primary and secondary diagnoses were changed. This study demonstrates that targeted education sessions for both junior clinicians and clinical coding staff can improve the accuracy of inpatient clinical coding.

Establishing continuum in Transcranial Doppler characteristics of IIH, migraine and healthy controls- An exploratory study.

BACKGROUND: IIH is a severe form of headache that often has superimposed migraine and often it is very difficult to distinguish the two forms of headache. Intracranial hemodynamics is a relatively unexplored means of distinguishing between the two forms of headache. OBJECTIVES: We aimed to study intracranial flow dynamics using Transcranial Doppler in patients with IIH, migraine, and normal controls. MATERIALS AND METHODS: It was a hospital-based observational study that included 51 people with IIH, 87 people with migraine, and 101 healthy controls and all were subjected to TCD study after detailed clinical examination. RESULTS: Mean age of patients in three groups were similar with the mean age in IIH being 33.41 ± 10.75 (age in years ± SD). Vision loss was present in 66.67% of patients with IIH, and most common field defect was generalized constriction (27.5%). Neuroimaging was abnormal in 94.11% of patients of IIH with mean CSF pressure was 31.27±5.32 cm of water. Of all the TCD-measured velocities, mean flow velocity (MFV) showed a significant difference in all three groups with (p-value <0.001). The pulsatility index, both for middle cerebral arteries as well as ophthalmic arteries showed a significant difference in the three groups with the highest values in IIH patients (p-value<.001). The mean VMR in IIH (1.11±0.32) was lower than the mean VMR in migraine (1.34±0.43) as well as controls (1.49±0.46). CONCLUSION: TCD parameters like MFV and PI are useful parameters that show considerable variation and can be used to differentiate between IIH and migraine.

A Neurological Complication in Rheumatoid Arthritis - A Scenario of Catastrophic Proportions.

Background: Rheumatoid Arthritis (RA) is a common systemic inflammatory disease that can present with a plethora of extraarticular manifestations. Many patients with RA from low- and middle-income countries do not get timely and adequate treatment with disease-modifying therapies. This results in the perpetuation of a chronic inflammatory state. Focus: Rheumatoid vasculitis (RV) is one of the most aggressive complications of RA resulting from a prolonged proinflammatory milieu. Usually, it has the involvement of multiple organ systems, with cutaneous manifestations being the most common. Neurological presentation is uncommon but severe when present. Highlight: We present a case of severe RV presenting with an unexpected neurological complication consisting of cranial and peripheral neuropathy with small vessel disease and intracerebral haemorrhage. We intend to highlight the morbidity and long-term consequences of inadequately treated RA, the most common inflammatory disease of the connective system especially in light of the neurological presentation.

Smartphone-Based Telestroke Vs"Stroke Physician" led Acute Stroke Management (SMART INDIA): A Protocol for a Cluster-Randomized Trial.

Background: One of the major challenges is to deliver adequate health care in rural India, where more than two-thirds of India's population lives. There is a severe shortage of specialists in rural areas with one of the world's lowest physician/population ratios. There is only one neurologist per 1.25 million population. Stroke rehabilitation is virtually nonexistent in most district hospitals. Two innovative solutions include training physicians in district hospitals to diagnose and manage acute stroke ('Stroke physician model') and using a low-cost Telestroke model. We will be assessing the efficacy of these models through a cluster-randomized trial with a standard of care database maintained simultaneously in tertiary nodal centers with neurologists. Methods: SMART INDIA is a multicenter, open-label cluster-randomized trial with the hospital as a unit of randomization. The study will include district hospitals from the different states of India. We plan to enroll 22 district hospitals where a general physician manages the emergency without the services of a neurologist. These units (hospitals) will be randomized into either of two interventions using computer-generated random sequences with allocation concealment. Blinding of patients and clinicians will not be possible. The outcome assessment will be conducted by the blinded central adjudication team. The study includes 12 expert centers involved in the Telestroke arm by providing neurologists and telerehabilitation round the clock for attending calls. These centers will also be the training hub for "stroke physicians" where they will be given intensive short-term training for the management of acute stroke. There will be a preintervention data collection (1 month), followed by the intervention model implementation (3 months). Outcomes: The primary outcome will be the composite score (percentage) of performance of acute stroke care bundle assessed at 1 and 3 months after the intervention. The highest score (100%) will be achieved if all the eligible patients receive the standard stroke care bundle. The study will have an open-label extension for 3 more months. Conclusion: SMART INDIA assesses whether the low-cost Telestroke model is superior to the stroke physician model in achieving acute stroke care delivery. The results of this study can be utilized in national programs for stroke and can be a role model for stroke care delivery in low- and middle-Income countries. (CTRI/2021/11/038196).

Seronegative panencephalitis complicated by viral encephalomyelitis in a case of Good's syndrome - a neuropathological report.

BACKGROUND: The role of thymus in the immune cascade of the body is still under active clinical scrutiny. Meanwhile, there is an unravelling of myriad presentations of thymoma with effects on various organ systems. These effects arise both due to autoimmunity or a paraneoplastic process secondary to thymoma. However, an occasional patient can be a conundrum and may give no clue regarding the pathogenesis and etiology of its clinical profile. MATERIAL AND METHODS: We present an enigmatic case of a 30-year-old male presenting with superficial fungal infections followed by multiaxial neurological involvement against a background of thymoma. Extensive workup for bacterial, viral, autoimmune and paraneoplastic etiologies were negative. Thymectomy confirmed thymoma (Type AB) but failed to ameliorate the progression of symptoms. He developed recurrent episodes of severe sepsis which remitted with sensitive antibiotics only to reappear again. Immunological profile showed complete absence of peripheral circulating B-cells with reversal of CD4/CD8 ratio, findings compatible with Good's syndrome. Radiological findings showed only progressive brain atrophy without any hyperintensity. He was also treated with intravenous immunoglobulins but failed to respond with the same. RESULTS: Autopsy revealed features of panencephalitis (neuronophagia, neuronal loss, perivascular lymphocytic cuffing and microglial nodules) with virus particles detected ultrastructurally. Although the distinction between seronegative autoimmune encephalitis versus a viral encephalomyelitis often blurs histologically, we speculated viral encephalomyelitis to have happened toward the latter part of his long illness. To our knowledge, this is a case of Good's syndrome presenting with seronegative autoimmune panencephalitis superimposed with a viral infection.

Tolosa-Hunt Syndrome and IgG4 Diseases in Neuro-Ophthalmology.

Tolosa-Hunt syndrome (THS) remains a challenging diagnosis for many neurologists. Often believed to be a rare presentation, the classical presentation is known to involve cranial nerves and tissues surrounding the cavernous sinus. Traditionally, a diagnosis of THS is considered when all secondary conditions have been ruled out. Yet, newer findings have elaborated a complex pathogenetic process with some overlap from the IgG4 spectrum of disorders, with which it shares many phenotypic similarities. In this narrative review, we present an updated picture of the condition focusing on the latest developments in the pathogenesis, diagnosis, and clinical management of these two conditions and use illustrative examples to highlight the salient features of this rare presentation.

Clinical profile and outcome of non-COVID strokes during pandemic and the pre pandemic period: COVID-Stroke Study Group (CSSG) India.

BACKGROUND: As the health systems around the world struggled to meet the challenges of COVID-19 pandemic, care of many non-COVID emergencies was affected. AIMS: The present study examined differences in the diagnosis, evaluation and management of stroke patients during a defined period in the ongoing pandemic in 2020 when compared to a similar epoch in year 2019. METHODS: The COVID stroke study group (CSSG) India, included 18 stroke centres spread across the country. Data was collected prospectively between February and July 2020 and retrospectively for the same period in 2019. Details of demographics, stroke evaluation, treatment, in-hospital and three months outcomes were collected and compared between these two time points. RESULTS: A total of 2549 patients were seen in both study periods; 1237 patients (48.53%) in 2019 and 1312 (51.47%) in 2020. Although the overall number of stroke patients and rates of thrombolysis were comparable, a significant decline was observed in the month of April 2020, during the initial period of the pandemic and lockdown. Endovascular treatment reduced significantly and longer door to needle and CT to needle times were observed in 2020. Although mortality was higher in 2020, proportion of patients with good outcome were similar in both the study periods. CONCLUSIONS: Although stroke admissions and rates of thrombolysis were comparable, some work flow metrics were delayed, endovascular stroke treatment rates declined and mortality was higher during the pandemic study period. Reorganization of stroke treatment pathways during the pandemic has likely improved the stroke care delivery across the globe.

Infectious ophthalmoplegias.

Though infections account for a significant proportion of patients with ocular motor palsies, there is surprising paucity of literature on infectious ophthalmoplegias. Almost all types of infectious agents (bacteria, viruses, fungi and parasites) can lead to ocular motor palsies. The causative infectious agent can be diagnosed in most cases using an orderly stepwise approach. In this review we discuss how to approach a patient with ophthalmoplegia with main focus on infectious etiologies.

Mechanical Thrombectomy in Embolic Cardiac Myxoma: Case Report and Literature Review.

Myxomas are the most common cardiac tumors and present clinically with cardiac manifestations, systemic constitutional symptoms, and embolic events. Posterior circulation involvement occurs in approximately 20 percent of cerebral ischemic events.The endovascular technique is an established life-saving therapy for eligible patients upto 24 hours from symptom onset. However, the role of endovascular management in embolic atrial myxoma remains unknown with no international consensus guidelines for the management of stroke in such patient population. Here, we present a case report of an embolic posterior circulation stroke in a young female treated with mechanical thrombectomy at 23 hours from symptom onset. To the best of our knowledge, this is the first thrombectomy case in posterior circulation with embolism from myxoma. Further workup confirmed an atrial myxoma which was resected. We also review the previous cases with mechanical thrombectomy done in such cases.

Temporal lobe epilepsy with amygdala enlargement: A systematic review.

Temporal lobe epilepsy (TLE) with enlargement of the amygdala (AE) is a distinct clinical entity with contrasting clinical features from TLE with hippocampal sclerosis (HS). The objectives of this systematic analysis were to study the clinical characteristics and treatment outcome of people with TLE with AE. Pubmed, Embase, Cochrane, Web of Science, Scopus, and Medline were searched using the keywords amygdala enlargement, temporal lobe epilepsy, epilepsy, and seizure in November 2020. We found 18 studies that satisfied the inclusion criteria. A total of 361 patients were included in this analysis. The mean age of onset was 36.2 years, and febrile seizure was uncommon compared to TLE with HS subjects. The type of aura and automatism was similar to TLE with HS, though less prevalent. Electroencephalography (EEG) was usually concordant with the side of AE. Anti-seizure medications (ASM), surgical, and immunotherapy were used in different studies. 86 patients underwent surgery with Engel I outcome in 69.7%. Histopathology of the resected samples was predominantly dysplasia and gliosis. A group of patients that responded well to immunotherapy with subsequent reduction of amygdala volume (AMV) purported an autoimmune etiology of AE. Heterogeneity was the main drawback that prevented comparability among the studies. The methods of measurement of AMV also differed widely in the included studies, and standardization of its method is still lacking. This analysis suggests TLE with AE as a distinctive group of patients either due to a developmental anomaly or autoimmune etiology.

Utility of Imaging of Nigrosome-1 on 3T MRI and Its Comparison with 18F-DOPA PET in the Diagnosis of Idiopathic Parkinson Disease and Atypical Parkinsonism.

BACKGROUND: Loss of nigrosome-1 on 3T and 7T magnetic resonance imaging (MRI) is a recently explored imaging biomarker in the diagnosis of neurodegenerative parkinsonism. OBJECTIVES: This study was undertaken to evaluate the utility of imaging of nigrosome in the diagnosis of neurodegenerative parkinsonism on 3T MRI. METHODS: An institution-based prospective case-control study was conducted at a tertiary care center in North India. 3T venous blood oxygen level-dependent (VenoBOLD) and high-resolution susceptibility-weighted imaging (SWI) imaging sequences in MRI were performed in 100 patients with parkinsonism (56 with idiopathic Parkinson's disease [IPD], 30 with young onset Parkinson's disease [YOPD], 12 with progressive supranuclear palsy, and 2 patients with multiple system atrophy) and 15 controls. Grading of nigrosome was done in both the sequences. Each patient underwent 18F-DOPA positron emission tomography (PET), detailed neurological examination including Hoen and Yahr (H&Y) staging and Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) scoring. RESULTS: The diagnostic sensitivity and specificity of the detection of loss of nigrosome-1 on VenoBOLD and SWI sequence at 3T MR imaging were 90% and 66.7% and 94% and 80%, respectively. A weak negative correlation was found between the grading of the nigrosome and clinical parameters (H&Y and UPDRS III). There was no correlation between the side of nigrosome loss and clinical asymmetry. However, nigrosome imaging was not able to differentiate between Parkinson's disease and atypical parkinsonism. CONCLUSIONS: The loss of nigrosome-1 on 3T MRI on SWI and VenoBOLD sequences may serve as a potential imaging marker in the diagnosis of degenerative parkinsonian syndromes. However, it cannot differentiate between idiopathic Parkinson's disease and atypical parkinsonian syndromes.

Magnetic resonance imaging (MRI) versus computed tomographic scan (CT scan) of brain in evaluation of suspected cavernous sinus syndrome.

BACKGROUND AND PURPOSE: The cavernous sinus is a unique region owing to anatomical factors and the pathologies affecting it. The diagnosis of cavernous sinus syndrome (CSS) predominantly relies on clinicoradiological correlation. We studied the utility of computed tomographic (CT) scan versus magnetic resonance imaging (MRI) in the diagnosis of CSS. METHODS: A prospective observational study was conducted in a tertiary care center in north India. All patients presenting with a clinical syndrome of cavernous sinus involvement with radiologically confirmed lesions were enrolled in the study. MRI and CT scan with cavernous sinus cuts were done and reviewed by experienced neuroradiologists for cavernous sinus lesions and compared with the final diagnosis. Sensitivity and specificity were calculated. RESULTS: We included 48 patients in our study. A final diagnosis was achieved in 41 out of 48 (85.6%) patients. Fungal infections (16 (33.3%)) constituted the commonest cause of CSS, followed by neoplastic involvement (13 (27.1%)) and Tolosa-Hunt syndrome (12 (25%)). Vascular involvement was seen in three (6.3%) patients. Other rare causes were seen in four (8.3%) patients. CT scan had an overall sensitivity of 14.6% in achieving a final diagnosis, whereas MRI had an overall sensitivity of 70.7%, with a statistically significant difference (p < 0.001). CONCLUSIONS: Although CT scan is a relatively cheap and accessible resource, its role in CSS diagnosis and management is limited because of poor yield. Hence, it is prudent to do an MRI as an initial investigation in cases of CSS.
