Camilleri-Brennan et al reported the Patient Generated Index (PGI) to monitor the quality of life in patients with rectal cancer. It can be used for other illnesses as well. The authors are from Ninewells Hospital in Dundee, Scotlan.
Steps to generating the PGI:
(1) Identify up to 5 items affected by the disease that are important to the patient.
(2) Add 2 items – comorbid health conditions and nonhealth issues.
(3) Score each of the items (up to 7) from 0 to 10, with 0 being worse imaginable and 10 ideal.
(4) Tell the patient that s/he has 14 points to distribute over the 7 items based on how important they are to the patient.
subscore for each item =
= (score from 0 to 10) * (number of points assigned) / 14
total PGI =
= SUM(all 7 subscores)
Interpretation:
• minimum score: 0
• maximum score: 10
• The higher the score the better the quality of life.
• The score can be used pre- or post-operatively or monitored over time.
