Evaluation of satisfaction and reasons for participation in a Covid-19 vaccine clinical trial: A single-centre, observational study

BACKGROUND In May 2020, WHO recognized the role of extensive immunization for interrupting the transmission of the SARS-CoV-2 virus. The development of such vaccines in clinical trials relies upon participants who are expected to be vested in the research process. Assessment of participant factors such as motivation and satisfaction are hence important to gauge perspective and ensure successful conduct and completion of these trials. METHODS We administered a validated three-domain questionnaire to and documented the binary categorical responses (yes/no) of participants (after informed consent) who had taken both doses of COVOVAX™ in a phase 3 trial at our institute. Association of the dependent variables (participant responses) with the independent variables (participant demographics and socioeconomic strata) was computed using Chi-square test at 5% significance. In case of a significant association, Bonferroni post-hoc test was applied for multiple comparisons. RESULTS Of the 78 participants who were administered the questionnaire, two-thirds were highly satisfied with their experience at our site. Gaining access to a new vaccine was a primary motivation overall (74%) and also in graduates (p=0.03) and middle-class population (p=0.002), whereas the lower-middle class population (p<0.0001) and those educated till secondary school (p=0.003) took part due to the long wait for government-approved vaccines. CONCLUSION Participants in a Covid-19 vaccine trial at Mumbai were largely satisfied with the care given to them though altruism did not feature as a primary reason for participation.

Medical case reports published in PubMed-indexed Indian journals in 2015: Adherence to 2013 CARE guidelines

In 2013, an independent group of researchers developed the CARE guidelines, a checklist to standardise reporting of case reports. This study assesses adherence to CARE guidelines among PubMed-indexed Indian medical journals in 2015 and the extent of endorsement of these guidelines by the journals. Case reports published in 2015 in journals indexed by PubMed, belonging to the medical stream, currently active, and that had an impact factor were included for analysis. Case series and journals that were published from India but for another country were excluded. Total adherence score and classification of adherence as “excellent”, “very good”, “good”, and “poor” as also adherence to individual components of the checklist were the outcome measures. A total of 162 journals were identified by the search strategy, of which 36 satisfied the selection criteria. In these 36 journals, 1178 case reports were published. We tested the association between the type of journal and impact factor with adherence by using the chi-squared test and generated crude odds ratios. All analyses were done at 5% significance. Based on the total percent score, no case report had excellent adherence, and 19% had good, 70.7% average, and 10% poor adherence, respectively. Among the sub-items, the best adherence was seen in the clinical findings [97.9%], followed by keywords [88.5%], and introduction [71.5%]. The items with extremely poor adherence were patient perspective [0%], informed consent [2.8%], and timeline [4.6%]. Journals with an impact factor of more than 1 had better adherence, relative to those with an impact factor lower than 1. Only one journal’s website mentioned the CARE guidelines. Greater awareness needs to be created among authors, peer reviewers, and editors about using these guidelines. As informed consent is a metric of autonomy, all stakeholders must ensure its reporting.

Use of computerized tests to evaluate psychomotor performance in children with specific learning disabilities in comparison to normal children.

Background & objectives: Children with specific learning disabilities (SpLD) have an unexplained difficulty in acquiring basic academic skills resulting in a significant discrepancy between their academic potential and achievements. This study was undertaken to compare the performance on a battery of six psychomotor tests of children with SpLD and those without any learning disabilities (controls) using computerized tests. Methods: In this study, 25 children with SpLD and 25 controls (matched for age, socio-economic status and medium of instruction) were given three training sessions over one week. Then children were asked to perform on the six computerized psychomotor tests. Results were compared between the two groups. Results: children with SpLD fared significantly worse on finger tapping test, choice reaction test, digit picture substitution test and card sorting test compared to the controls (p<0.05). Interpretation & conclusions: Children with SpLD have impairment of psychomotor skills like attention, sensory-motor coordination and executive functioning. Further research is needed to evaluate if the remedial education plan results in improvement in psychomotor performance of children with SpLD on these selected tests.

Principles of sample size calculation.

In most areas in life, it is difficult to work with populations and hence researchers work with samples. The calculation of the sample size needed depends on the data type and distribution. Elements include consideration of the alpha error, beta error, clinically meaningful difference, and the variability or standard deviation. The final number arrived at should be increased to include a safety margin and the dropout rate. Over and above this, sample size calculations must take into account all available data, funding, support facilities, and ethics of subjecting patients to research.

Off-label drug use in a pediatric intensive care unit.

Objective. To determine the extent and nature of off-label drug use in children admitted to a Pediatric Intensive Care Unit (PICU) Methods. This prospective exploratory study was conducted in a tertiary care hospital in a metropolitan city in India after obtaining clearance from the institutional ethics committee. Subjects admitted in PICU from February-August 2006 were enrolled in the study. In addition to the demographic data and diagnosis, details of drugs prescribed (name, dose and route and frequency of administration) were obtained from hospital records. British National Formulary 2005 was used to determine if the prescriptions were off-label and if so, they were categorized as off-label for age, indication, dosage or frequency and route of administration. Descriptive statistics was used to determine the proportion of off-label drug use. Fischer’s exact test was used to determine if there was significant difference (P<0.05) in off-label use between patients with multiple system affection and those with single system affection and between those requiring artificial ventilatory support and those not requiring it. Results. Three hundred subjects received 2237 analyzable prescriptions. Of these 1579 (70.58%) prescriptions were offlabel in nature. Off-label drug use was prevalent in all age-groups and in all systemic afflictions. The proportion of off-label drug use was not influenced by severity of illness, as judged by involvement of multiple systems or need for ventilatory support. The list of off-label drugs used included old as well as new molecules. Most commonly used drugs in PICU were also the most common off-label drugs. Conclusion. Off-label drug use is highly prevalent in PICU settings.

A retrospective analysis of adverse events in the elderly in a tertiary referral center in Mumbai (Bombay), India.

Background : Adverse events (AEs) account for significant morbidity and mortality in elderly. Inappropriate medication usage has been regarded as an important factor contributing to AEs in them. Beers criteria are a set of standard criteria for guiding drug prescription in elderly. Objective : To estimate the burden of AEs in the elderly in India and use of Beers criteria for assessing appropriateness of drug prescription in them. Materials and Methods : Data on AEs collected by our tertiary referral center for the years 2005 and 2006 was analyzed. The term 'elderly individuals' was defined as those aged ≥58 years. An AE was defined as any untoward medical occurrence with a medicinal product in a patient or a clinical investigation, whether or not causally related. Results : In 2005, 321 AEs were reported, and in 2006 there were 673. Of them, those in the elderly constituted 60 (18.9%) and 44 (11.8%) AEs in the 2 years, respectively. About 7 (11.6%) of the AEs in elderly in 2005 were due to medications fulfilling Beers criteria but none in 2006. Two thirds of the AEs in both years were found to be due to antidiabetics, oral anticoagulants and antiplatelets and drugs with a narrow therapeutic index. Warfarin, digoxin and insulin accounted for a quarter of the AEs. Conclusions : Some commonly used medications account for a major proportion of AEs in elderly. Prospective studies of similar nature could further help us assess the burden of AEs in elderly.

Off-label drug use in children.

OBJECTIVE: To determine the extent and nature of off-label drug use in children admitted to a pediatric general ward in a tertiary health care centre METHODS: Consecutive patients aged 1 mo-12 years admitted to the general wards in a tertiary care center in Mumbai over a two-month period were prospectively enrolled in the study. British National Formulary [BNF] version 2005 was used to ascertain if the drug use was "off-label". The off-label use was categorized as: administration of a greater/lesser dose, administration at a higher/lower frequency than indicated, administration for indications not described, administration of a drug not licensed for use in that age group and/ or use of alternative routes of administration. Descriptive statistics was used for calculating the off-label drug use. RESULTS: Two thousand prescriptions received by 600 subjects (M:F= 1.47:1) were analyzed. One thousand and forty-five (50.62%) prescriptions were off-label. The off-label drug use rate was 1.74+/-1.56 per patient. The maximum rate of off-label drugs was in infants (2.33/patient). 'alteration in dosage' was by far the commonest reason for off-label use; followed by 'age' and 'indication'. Furosemide (i. v.), diazepam (i.v), cefotaxime (i.v), ethambutol (tab) and prednisolone (tab) were the five commonest off-label drugs used in the study population. CONCLUSIONS: Off-label drug use was highly prevalent in general pediatric ward of a tertiary care hospital in India.

Reporting ethical processes in two Indian journals.

Background: In biomedical journals, authors are expected to report if the study was carried out in accordance with international and national ethical guidelines and inform readers if approval from ethics committee was obtained and if written informed consent was taken from the participant or legal guardian. Aims: To determine the proportion of research manuscripts in two pediatric journals published from India reporting on ethical clearance, obtaining of informed consent and/or assent. Settings and Design: Retrospective study for analysis of research articles published. Materials and Methods : Research articles published in the issues of Indian Pediatrics and Indian Journal of Pediatrics in 2006 were reviewed for reporting regarding ethical clearance, obtaining written informed consent from guardians or parents, and obtaining assent from research participants. Statistical Analysis Used: Descriptive statistics was used. The number of articles according to their types; the number of research designs employed according to their types; and the number of research studies mentioning ethical clearance, consent, and assent were expressed as percentages mentioning ethical clearance, consent and assent were expressed as percentages. Results: Of the 132 manuscripts reporting biomedical research, 39 (29.53%) reported having obtained approval from the ethics committee. Forty-six of the 98 (46.94%) manuscripts reporting on prospective studies indicated that informed consent was obtained from parents or lawful guardians. Neither ethical approval nor informed consent was mentioned in 45 (34.10%) published articles reporting prospective studies. A total of 54/98 (55.1%) studies enrolled children aged 7 years or more and hence were assessed for reporting of assent; eight (14.81%) reported that children's assent was obtained. Only four (7.41%) eligible studies reported ethics committee's approval, informed consent, as well as assent. Conclusions: A significant proportion of research articles published in the two pediatric journals did not provide information regarding ethical approval, written informed consent, and obtaining of assent.

Anticonvulsant hypersensitivity syndrome to lamotrigine confirmed by lymphocyte stimulation in vitro.

Anticonvulsant hypersensitivity syndrome (AHS) developing to lamotrigine, a non-aromatic anticonvulsant, has rarely been reported. We present a two-year-old boy with refractory epilepsy on valproic acid and lamotrigine therapy who developed fever and a maculopapular itchy rash. Blood investigations detected lymphocytosis and thrombocytopenia. With a presumptive diagnosis of AHS, lamotrigine was discontinued. The fever and rash resolved over the next three days and the child was discharged on valproic acid and clobazam. The diagnosis was confirmed by in vitro lymphocyte toxicity assay, which not only demonstrated increased cell death following exposure to lamotrigine, but also to the three first-line aromatic anticonvulsants: phenytoin, phenobarbital and carbamazepine. The potential of first-line aromatic anticonvulsants to cause AHS should be remembered in a patient who has developed AHS on exposure to lamotrigine. Timely recognition of this rare but potentially fatal drug reaction is important.

Improving drug safety monitoring.

Drug safety monitoring is important in children. Young age, polypharmacy, prolonged hospitaliza-tion, being critically ill and use of unlicensed and off-label drugs have been identified as risk factors which predispose a child to experience an adverse drug reaction. In our country, the HIV/AIDS epidemic, setting up of intensive care units, increasing availability of imaging studies, and the introduction of several new drugs and vaccines have accentuated the need for improving drug safety monitoring in children. To achieve this aim, establishing in-hospital computerized event monitoring program in major hospitals and an effective national post- marketing drug surveillance network are the need of the hour.
