Medical kits should be evaluated and updated for each trip taking into consideration factors such as duration, terrain to be encountered, distance to medical facility/care, diseases endemic to travel destination, as well as level of expertise of personnel on trip.
Supplies generally divided into five categories:
avoid bringing equipment that requires a high level of skill, as misuse or mismanagement of medical condition/injury may lead to more harm than utilizing basic interventions or doing nothing at all until evacuation and transport to proper medical facility can be acquired.
Important to label and organize kit in a way that allows for quick location of medications/tools if need for their use should arise.
Store commonly-used items and those to be used in life-threatening situation in more easily accessible places in pack.  Less frequently used items can be stored deeper in pack if necessary to optimize  space.
Type of container used depends on user preference as well as travel factors such as duration of trip and environment to be encountered.
When determining how much of each supply (e.g. medication or bandages) to bring, take into consideration factors such as duration of trip, access to formal medical care, likelihood of illness/injury requiring use of item, maximum number of participants that may require resource at one time, to name a few.
