Other medical institutions are healthcare facilities that provide clinical services but do not fit a more specific category, such as a hospital, GP surgery or dental practice. Their work varies according to the services offered and may include consultations, assessments, diagnosis, treatment, monitoring and follow-up care. Some are run by the NHS, while others operate independently or as charitable organisations. Customers may find specialist outpatient clinics, medical assessment or diagnostic centres, rehabilitation services, day-treatment facilities, hospices and other forms of community-based care in this category. Services can include nursing support, physical or occupational therapy, tests and scans, wound care, symptom management and support for people with long-term or serious conditions. The staff, treatments and referral arrangements differ between institutions; some accept self-referrals, while others require a referral from a GP or another healthcare professional.
