Materials and Methods: In this study, six configurations using cold vaccine boxes or bags made with different materials, with and without insulation, of different sizes, and number of coolant-packs were used to simulate the configuration used by the pharmaceutical wholesalers for transportation of vaccine. Model vaccines (vial, n=10) were packed using these six configurations which then stored in an incubator at 38℃ and monitored for 24 hours. Each configuration was tested repeatedly for 5 times.
Results: In term of compliance to 2℃-8℃, four out of six tested configurations are effective in cold chain transportation. The effectiveness is highly dependent on the type of passive containers used, size of cold boxes, insulation, and number of coolant-packs. The configuration with a larger polystyrene foam box with five coolant-packs maintained the required temperature up to 23 hours. In contrast, configurations using a polystyrene foam box with four coolant-packs and a large vaccine cold box with two coolant-packs failed to reach below 8℃ throughout the 24 hours.
Conclusion: Packaging method, the material and size of the container could have a direct impact on the effectiveness of cold chain temperature maintenance. Polystyrene foam box, cold box with polyethylene interior lining and polypropylene insulation, a cooler bag with proper number of ice packs could be effectively used for transportation of vaccines within their respective transportation duration allowance.
AIM: The study aimed to understand the experiences of parents of children with thalassemia related to their family, financial, social, treatment, and psychological issues in Pakistan.
METHODS: This descriptive phenomenological study recruited 21 parents of children with thalassemia through purposive sampling until data saturation was achieved. Analysis of transcribed interviews was performed through Colaizzi's method and themes and subthemes revolving around diagnosis, challenges, and treatment issues were extracted.
FINDINGS: A total of 21 Pakistani parents participated in this study. Most of the participants were females (n = 16, 76.19%), housewives/stay-at-home moms (n = 13 (61.90%), and were uneducated (n = 6, 28.57%). Regarding genetic traits, only three (14.28%) parents declared that they had genetic traits of thalassemia. The findings of our study revealed that thalassemia is enormously influenced by psychosocial and economic problems because of this disease in their families.
CONCLUSION: Our findings indicated that parents of these children face multi-faceted challenges, such as physical, socio-emotional, financial, and familial. These findings may lead to an adequate understanding of their individual needs and efficient utilization of supportive and care programs.
PRACTICE IMPLICATIONS: An understanding of such experiences, involving those distinctive to Pakistani culture, is especially vital to inform the care of these children and enhance their quality of life.
