Awareness and outlook of health-care professionals regarding materiovigilance in a tertiary care teaching hospital in South Rajasthan

Background: Post-marketing surveillance regulates the safety, quality, and performance of medical devices (MDs). Medical professionals play a key role in the monitoring and reporting of MD Adverse Events (AEs). Since the launch of Materiovigilance (MV) Programme of India, very few published studies were found regarding reporting of MDAE. Aim and Objective: This study aims to know about awareness and outlook of medical professionals regarding MV. Materials and Methods: A cross-sectional study done among medical professionals of various specialties in a tertiary care teaching hospital in South Rajasthan. A pre-validated questionnaire was circulated to 200 doctors containing questions related to knowledge, attitude and practice of MV. Results: About 58.6% of the doctors came to know about the term MV during this study. About 76.7% of participants knew that MD could lead to an AE, but only 11.2% of the participants had the correct knowledge of how to report an AE related to MD. About 66.8% of participants had positive attitude regarding reporting of AE, 23.7% reported the event and 66.6% did not report as they found them mild. Conclusion: Majority of doctors had the knowledge about reporting of AEs, but they were largely unaware of the term MV. Knowledge regarding where to report is very limited. Despite adequate level of knowledge, reporting practices are very limited. Hence, there is a need for regular sensitization and training programs to foster the habit of reporting AE related to MD even if they are mild.

Trombocitopenia severa inducida por un oclusor para DAP: reporte de caso en tecnovigilancia

Introducción: El ductus arterioso persistente (DAP) es una cardiopatía congénita de especial interés. La oclusión intervencionista es el tratamiento de elección, no obstante, el dispositivo médico "oclusor para DAP", usado en este procedimiento, puede dar lugar a la aparición de eventos adversos de rara frecuencia como hemorragia, trombocitopenia, entre otros. Reporte de caso: Se presenta un caso de una paciente pediátrica con trombocitopenia severa posterior a la intervención. Durante su hospitalización, la paciente mantuvo niveles bajos de plaquetas hasta que logra su recuperación y sale de alta sin una nueva manifestación hematológica. El caso fue reportado como sospecha de incidente adverso asociada al oclusor para DAP. Conclusión: Al realizarse el análisis causa-raíz, se concluye que el tamaño del oclusor para DAP podría ser la principal causa de la trombocitopenia. El presente caso es una muestra que los dispositivos médicos pueden causar eventos adversos severos, por lo que, es necesaria la implementación de tecnovigilancia, principalmente a los dispositivos médicos de alto riesgo.

Introduction: Patent ductus arteriosus (PDA) is a congenital heart condition of special interest. Interventional occlusion is the treatment of choice; however, a PDA occlude, used in this procedure, is a medical device that rarely could lead to adverse events such as hemorrhage, thrombocytopenia, etc. Case report: We present a case of a pediatric patient with severe thrombocytopenia after surgery. During her hospitalization, platelet levels remained lower and, finally, she was fully recovered without any hematological manifestation. The case was reported as a suspected adverse incident related to PDA occlude. Conclusion: After performing a cause-root analysis, we concluded that the size of the PDA occlude may be the main cause of thrombocytopenia. This case demonstrates that medical devices could lead to adverse events. Thus, it is important for clinicians to implement medical device surveillance, mainly for high-risk medical devices.

Changes in Registration Status of Identification Codes on PMDA’s Information Search Site of Pharmaceuticals for Prescription / 医薬品情報学

The identification code of a drug is defined as “a code for identifying tablets, etc.” and is described in the “Composition/Properties” section of the package insert. We investigated whether the Pharmaceuticals and Medical Devices Agency (PMDA) website, which allows users to search package insert information, can be used for drug identification using identification codes in 2019 before the new package insert guidelines were implemented, and in 2022, during the revision period. Approximately 30% of the investigated high-risk drugs were unidentifiable in both years. The most common reason was that images were used to register identification codes on the PMDA website, and character strings were not searchable. We then conducted a questionnaire survey of pharmaceutical companies, and only approximately half of the respondents opined that it would be preferable if the registration format for identification codes was established within the pharmaceutical industry. However, hospital pharmacists urged for more simplified identification of drugs on the PMDA website.

Mapeamento dos bancos de dados em dispositivos médicos: revisão narrativa e o cenário brasileiro para avaliação com dados de mundo real (RWD) / Mapping of database in medical devices: review and the Brazilian scenario for evaluation with real world data (RWD)

Objetivo: Pretendeu-se mapear os bancos de dados governamentais em dispositivos médicos, na perspectiva pública com o intuito de contribuir como fonte para gerar dados de mundo real (RWD) e potencial para subsidiar estudos de Avaliação de Tecnologias em Saúde (ATS). Métodos: Realizada revisão narrativa na base de dados do Embase. Os critérios para inclusão de elegibilidade foram: i) dimensão ampla de RDW nos processos de gestão de tecnologias; e ii) aplicação de RDW em processos regulatórios, cobertura e ATS. Também foram consultados os sistemas do Ministério da Saúde e da Anvisa. Resultados: A busca retornou 1.185 resultados; após leitura dos resumos, foram selecionados 29 artigos, sendo 5 incluídos. Na consulta ao catálogo do Datasus, foram localizados 262 sistemas informatizados; após análise da descrição sumária e principais objetivos, foram selecionados 12 sistemas que geram dados sobre dispositivos médicos. A falta de interoperabilidade dos sistemas é recorrente e a ausência de uma nomenclatura padronizada é um desafio a mais. Conclusão: Há crescente discussão do uso de RWD para subsidiar ATS em todo o ciclo de vida tecnológico, desde regulação até monitoramento do uso, como também para subsidiar análises de custo-efetividade e benefícios clínicos. Assim como nos demais países, o Brasil sistematizou inicialmente os dados administrativos para atender às demandas comerciais e financeiras. Os sistemas não geram dados dos resultados clínicos. São disponibilizados dados das tecnologias dispensadas e dos valores repassados e não são coletadas as informações dos benefícios do uso dessas tecnologias. Com a evolução dos métodos de ATS, a utilização de RWD tornou-se relevante.

Objective: It was intended to map government databases on medical devices, in the public perspective, in order to contribute as a source to generate real world data (RWD) and potential to subsidize Health Technology Assessment (HTA) studies. Methods: A narrative review was carried out in the Embase database. The criteria for inclusion of eligibility were: i) broad dimension of RDW in technology management processes; and ii) application of RDW in regulatory processes, coverage and HTA. The systems of the Ministry of Health and Anvisa were also consulted. Results: Results: The search returned 1,185 results, after reading the abstracts, 29 articles were selected, 5 of which were included. The catalog of Datasus database were consulted, 262 summaries with the description and the main objectives were analyzed, 12 systems were selected systems that generate medical devices. The lack of interoperability of systems is recurrent and the absence of a standardized nomenclature is an additional challenge. Conclusion: There is a growing discussion about the use of RWD to subsidize HTA throughout the technological life cycle, from regulation to monitoring of use, as well as to subsidize the examination of cost-effectiveness and clinical benefits. As in other countries, Brazil has systematized administrative data for commercial and financial data demands. The systems do not generate data on clinical outcomes. Data provided are on dispensed technologies, on transferred values and are not collected on the benefits of using these technologies. With the evolution of HTA methods, the use of RWD has become relevant.

Medical devices associated adverse events under Materiovigilance Programme of India in a Tertiary Care Hospital of Tribal District of Odisha

Background: A materiovigilance program is a system that is used for the identification, collection, and reporting of possible adverse reactions resulting from the use of medical devices. This monitoring program ensures the safety of patients and aids the post-marketing surveillance process. The Materiovigilance Programme of India (MvPI) was launched on July 6, 2015. Aims and Objectives: The primary objective of the study was to generate evidence based data on the safety of the medical devices used in our institute and to analyze the risk benefit ratio of reported adverse events of medical devices and to communicate the safety information to the stake holders. The secondary objective was to educate and advocate the concept of MvPI and creating a culture of adverse events reporting among health workers. Materials and Methods: A retrospective study was conducted after receiving clearance from the Institutional Ethical Committee, Saheed Laxman Nayak Medical College and Hospital (SLN MCH), Koraput. Data about Medical Device-Associated Adverse Events (MDAEs) were collected from MDMC, SLN MCH, Koraput, for the period from October 2019 to February 2022. MDAE reports were collected by a materiovigilance associate during the period from October 2019 to February 2022. Events were reviewed to verify whether or not they were documented in patient’s electronic records and a database of devices was created, which included the events associated with each device. Device-related MDAEs were classified by patient characteristics and the medical devices used. Results: In the 15-month study period, a total of 56 cases of MDAE were reported to MDMC, SLN MCH, Koraput. Of these, 17.9% MDAEs (10 cases) were adverse events related to surgical gloves, 8.9% (five cases) were associated with pulse oximeters, 7.14% of cases (4 cases) were due to glucometer malfunctioning, and 7.1% were related to HIV diagnostic kits such as false positives and false negatives. Adverse events such as skin rashes, irritation on skin, itching, redness of eyes, and gum bleeding in patients with dental braces were reported. A majority of device defects involved inaccuracy in the data reported by the devices (seen in 10.7% of cases), while six cases were due to device malfunctioning. Conclusion: This study shows only the tip of iceberg of the reporting trends of MDME. There is inequality in reporting by different grades of health care workers and from different departments. It highlights the necessity of conducting awareness programs, training and workshops regularly. Device-related safety and reporting of device-related adverse events should be subject of attention and further research.
