RESUMEN
BACKGROUND: Abnormal laboratory values are a common reason for the exclusion of participants in clinical studies, increasing the recruitment time and cost during conduct. The use of sample-specific reference intervals (RIs) may help to address this issue. Hence, the present study derived site-specific RIs using the department laboratory database and compare the proportion of "out of range" (OOR) values between the new and the old RIs used by the trial site. METHODS: Institutional ethics committee approval was obtained. Data for hematology and biochemistry parameters were analyzed. Normality was assessed and RIs computed using nonparametric method. Data were partitioned for gender and descriptive statistics applied for demographics. The OOR values based on new RIs were compared with old RIs using Chi-squared tests. Between gender OOR proportions compared using Chi-squared test (significance at P< 0.05). Post hoc analysis was performed with Beasley's technique. RESULTS: Data of 601 participants were analyzed. The median (Inter Quartile Range) age was 22 (47) years and 64.72% were male. New RIs for key parameters were: Haemoglobin (9.3-16.5 g/dl), alanine aminotransferase (11.4-47.74 U/I), aspartate aminotransferase (8.8-58 U/I), total bilirubin (0.27-1.4 mg/dl), and creatinine (0.59-1.36 mg/dl). Post partitioning, the RI for hemoglobin (g/dl) was lower (8.72-15.72) in females. The proportion of OOR values were lower with new RIs relative to old laboratory RIs (P < 0.0001). CONCLUSION: A reduction in the proportion of OORs and a change in the upper and lower bound laboratory intervals with new RIs emphasize the need for sample-specific ranges to prevent unnecessary exclusions of volunteers from trials.
RESUMEN
PURPOSE: Clinical research in India has been besieged by controversies. While studies have addressed other stakeholders, few have addressed the patient. The present study was conducted to assess the extent of awareness and understanding about the nature and conduct of CR among people of Mumbai. METHODS: Institutional Ethics Committee approval was taken (EC/OA-12/15) and written informed consent was obtained. Adults who were residents of Mumbai were enrolled. A prevalidated and published 48-item questionnaire based on six themes, namely awareness and participation, voluntariness and autonomy, compensation, confidentiality, safety, and involvement in CR were administered. Perception based on themes and association of variables such as age, gender, socioeconomic class, and education on this perception was assessed. Descriptive statistics along with Chi-square test/Chi-square test for trend and crude odds ratio (cOR) were assessed. RESULTS: Of the 453 participants approached, 400 (age 32 [18-96]) consented. Only 210/400 (52.5%) were aware of CR and 194/400 (48.5%) said they needed permission for participation. Only 226/400 (56.5%) were aware of their rights and 111/400 (27.75%) felt that clinical trial participants received compensation. The socioeconomic class influenced awareness of CR (P < 0.00001; r 2= 0.495) as did the age (P < 0.0001; r 2= 0.82). Men were less likely to need permission to participate relative to women (cOR [95% confidence interval (CI)] 2.47 [1.6, 3.6] [P < 0.00001]). Those who had heard of CR were twice more willing to participate (cOR [95% CI] 1.72 (1.2, 2.6); P = 0.008). CONCLUSIONS: There is a greater need to improve awareness, especially about safety, compensation, and confidentiality in CR.
RESUMEN
PURPOSE: In pharmaceutical industry funded clinical studies (PIS), there is rigorous monitoring to ensure adequate and accurate data documentation. In comparison, the investigator-initiated studies (IIS) often lack in resources and may not follow such quality checks. At present, very limited data on the existing deficiencies in documentation for IIS are available. Hence, the present study assessed data quality in IIS relative to those funded by the industry to identify and address issues in data documentation. MATERIALS AND METHODS: We evaluated records of 1276 participants in 13 studies (5 - industry sponsored and 8 - investigator initiated) conducted during 2009-2015 using a prevalidated checklist. The percentage total scores for overall documentation and general trial-related and patient-specific documents were calculated. The percentage total scores within the patient-specific documents were also calculated and compared. Between-group score analysis was done by Student's t-test using GraphPad InStat version 5.0. RESULTS: The mean (standard deviation [SD]) percentage total score for the IIS was 80.96 (13.26) and that for PIS was 98.77 (1.84) (P = 0.01). For IIS, the total percentage scores ranged from 63% to 100% while it was above 95% for all PIS. For general trial-related documents, the mean (SD) percentage total score for IIS was 90.39 (13.26) while that for PIS was 97.38 (0.92) (P > 0.05). In the patient-specific documents, IIS scored 80.52 [14.41] versus 98.95 (1.98) for PIS (P = 0.016). The scores for IIS versus PIS (70.22 [21.6] and 99.36 [1.43]) within patient-specific documents were significant only for admission criteria (P = 0.016). CONCLUSION: Quality of IIS needs to be addressed by greater oversight and periodic quality control assessments.
RESUMEN
The quality of the written informed consent process is one of the most important aspects of clinical research, as it is the single tool that serves as a metric of autonomy. Several challenges have been identified with the informed consent process in developing countries the most important of which is the ability to assimilate and understand the information presented in the consent form. In India, a unique aspect of the informed consent process is the need for audio-video [AV] recording of the process for vulnerable populations and new chemical entities. The present narrative summates authors' experiences as investigators with A-V recording of the informed consent process as also providing a brief narrative review of relevant literature. It also offers potential solutions for challenges faced during this process.
