Connective tissue disease for Charlson index (primary care)
Name connective_charlson_gprd
Chapter Musculoskeletal diseases/Systemic connective tissue disorders
Definition
Acording to Charlson (1987), this category includes patients with SLE, polymyositis, MCTD, polymyalgia rheumatica, and moderate to severe rheumatoid arthritis.

Note that the ICD-10 codes (Sundararajan) are:
M050, M051, M052, M053, M058, M059 (rheumatoid arthritis),
M060, M063, M069 (rheumatoid arthritis, rheumatoid nodule),
M32 SLE,
M332 Polymyositis,
M34 Systemic sclerosis,
M353 Polymyalgia rheumatica,
but NOT: 
   M06.1 Adult-onset Still's disease,
   M06.2 Rheumatoid bursitis,
   M06.4 Inflammatory polyarthropathy,
   M06.8 Other specified rheumatoid arthritis.

Sjogren and dermatomyositis are also excluded. For this code list we will include dermatomyositis in category 4 (as it is a systemic disease) but not Sjogren as it is less commonly a multisystem disease. Category 3 is to be used for calculating the Charlson index.
