I've never worked in a clinic, so I cannot accurately convey clinic work to you.
I've worked as an LVN/LPN in LTC throughout the past 2 years, and it has its remarkable advantages and drawbacks. The benefits of LTC include the ability to build ongoing relationships with residents and family members, the routine nature of the job, the pay, and learning about hundreds of different meds.
The disadvantages of LTC include the lack of respect from the rest of the medical community, difficult family members who think you're out to abuse Grandma, understaffing, high employee turnover rates, high patient loads, and the rising acuity level of these elderly people.
I work on the rehab unit of a nursing home, and it is hellish due to the acuity level of the residents. My patients have all had recent surgeries and/or afflictions such as laminectomies, arthroplasties, kyphoplasties, hysterectomies, CABGs, CVAs, acute MIs, amputations, pneumonia, fractures, and the list goes on. The nursing home does not maintain adequate staffing, supplies, or amenities to care for these very sick people, yet their unreasonable family members expect the nursing staff to work wonders.
Though I've never worked in a clinic, it must be nice to not have to see the same patient 8 to 16 hours per day, every day, for several weeks. The clinic patients tend to be in and out, like a revolving door. In LTC, if I have a disgusting patient, I must deal with them every waking moment until they get discharged from the facility.
