Outpatients vs Inpatients

Medline:

Outpatients:

"Outpatients"[Mesh] OR "Outpatient Clinics, Hospital"[Mesh] OR "Ambulatory Care"[Mesh] OR "Ambulatory Care Facilities"[Mesh] OR "Community Health Services"[Mesh] OR "Community Health Centers"[Mesh] OR "Community Health Planning"[Mesh] OR "Community Medicine"[Mesh] OR "Primary Health Care"[Mesh:NoExp] OR "General Practice"[Mesh] OR "House Calls"[Mesh] OR "Day Care, Medical"[Mesh]

Now, some of these terms are narrower terms of Ambulatory Care Facilities. So you may be thinking, why not clean this up a bit? However, sometimes if you go too broad, you lose some of the narrowest terms (see my post about this) so I kept them in just to be sure to get everything.

Keywords: outpatient*[tiab] OR out-patient*[tiab] OR ambulatory[tiab] OR communit*[tiab] OR family practi*[tiab] OR "general practice"[tiab] OR general practitioner*[tiab] OR "primary care"[tiab] OR "primary health care"[tiab] OR "primary healthcare"[tiab] OR "family medicine"[tiab] OR "family health"[tiab] OR "office based"[tiab] OR officebased[tiab]

Additional MesH which may or may not be relevant to your question:
"Ambulatory Surgical Procedures"[Mesh] OR "Community Psychiatry"[Mesh] OR "Community Dentistry"[Mesh] OR "Community Health Workers"[Mesh] OR "Nurses, Community Health"[Mesh] OR "Primary Care Nursing"[Mesh] OR "Physicians, Primary Care"[Mesh] OR "Physicians, Family"[Mesh] OR "General Practitioners"[Mesh]

Nursing Homes and Group Homes are usually considered Outpatient rather than Inpatient, but make the best decision for your question:
"Residential Facilities"[Mesh]

These are sometimes inpatient and sometimes outpatient:
"Residential Treatment"[Mesh] OR "Long-Term Care"[Mesh]

Inpatients:

"Inpatients"[Mesh] OR "Hospitalization"[Mesh] OR "Hospital Units"[Mesh] OR Hospitals[Mesh] OR "Hospital Departments"[Mesh:NoExp] OR "Institutionalization"[Mesh] OR "Child, Hospitalized"[Mesh] OR "Child, Institutionalized"[Mesh] OR "Adolescent, Hospitalized"[Mesh] OR "Adolescent, Institutionalized"[Mesh]

Keywords: inpatient*[tiab] OR in-patient*[tiab] OR hospitaliz*[tiab] OR hospitalis*[tiab] OR residential*[tiab] OR institutionaliz*[tiab] OR institutionalis*[tiab] OR admitted[tiab] OR admission[tiab] OR readmission[tiab]

Additional MeSH which may or may not be relevant to your question:
"Health Facility Environment"[Mesh] OR "Anesthesia Department, Hospital"[Mesh] OR "Cardiology Service, Hospital"[Mesh] OR "Emergency Service, Hospital"[Mesh] OR "Nuclear Medicine Department, Hospital"[Mesh] OR "Obstetrics and Gynecology Department, Hospital"[Mesh] OR "Oncology Service, Hospital"[Mesh] OR "Psychiatric Department, Hospital"[Mesh] OR "Radiology Department, Hospital"[Mesh] OR "Surgery Department, Hospital"[Mesh] OR "Urology Department, Hospital"[Mesh]

This list does not include all of the departments listed under the MeSH term Hospital Departments – it focusses on the clinical ones. You may wish to check the list to make sure that nothing relevant has been missed.

Again, I selected the most clinical-sounding Health Facility Departments.
