Inclusion criteria
Inclusion criteria: 1. Developed a prosthetic joint infection as a primary or secondary discharge diagnosis (ICD-10 codes M00.0, M00.1, M00.2, M00.8, M00.9) 2. >3 months after having had a prosthetic joint inserted (OPCS-4 codes W37-W51)
Exclusion criteria
Exclusion criteria: Current exclusion criteria as of 12/11/2018: 1. NHS number is missing or cannot be derived using established algorithms from their other personally identifying data (name, date of birth, gender, address etc.). Any missing or corrupt records are also excluded 2. Prosthetic joint was inserted <3 months before the prosthetic joint infection are also excluded 3. Patients that do not want the confidential patient information held on them by NHS Digital (or NHSBSA) to be used in this, or other research, can use the National data opt-out programme (https://digital.nhs.uk/services/national-data-opt-out-programme ) to have it excluded. Patients can find out more and set their opt-out choice at: https://www.nhs.uk/your-nhs-data-matters/. Previous exclusion criteria: 1. NHS number is missing or cannot be derived using established algorithms from their other personally identifying data (name, date of birth, gender, address etc.). Any missing or corrupt records are also excluded 2. Prosthetic joint was inserted <3 months before the prosthetic joint infection are also excluded 3. Notified NHS Digital or NHSBSA that they do not wish their data to be shared for purposes other than their own direct care (known as a 'Type 2 Opt-Out')
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Incidence of invasive dental procedures in the 3 months immediately preceding a late prosthetic joint infection (LPJI) (case period) compared to the frequency of invasive dental procedures in earlier 3 month control periods (3-6, 6-9 and 9-12 month before LPJI), measured by linking national hospital diagnosis and procedure data with national dental treatment data | — |
Secondary
| Measure | Time frame |
|---|---|
| LPJI free survival following a course of dental treatment involving an invasive dental procedure (cases) compared to LPJI free survival following a course of dental treatment NOT involving an invasive dental procedure (controls) measured by linking national hospital diagnosis and procedure data with national dental treatment data. Invasive dental procedures are defined as extractions, dental scaling and endodontic (root canal) treatment. | — |
