- QI = quality improvement; PROM = patient-reported outcome measure; SD = standard deviation; NPRS = Numeric Pain Rating Scale; PSFS = Patient Specific Functional Scale; SBST = STarT Back Screening Tool; QBPDS = Quebec Back Pain Disability Scale; GPE-DV = Global Perceived Effect—Dutch Version. *The process indicator reflects a repeated measurement; pretreatment and posttreatment. †The process indicator reflects a single measurement; posttreatment. ‡The process indicator reflects a single measurement; pretreatment. §The outcome indicator reflects the change score between a pretreatment and posttreatment measurement. ||The outcome indicator reflects a single posttreatment measurement. #1 (absolutely satisfied) to 7 (absolutely unsatisfied). **The average reflects the scores of seven participants, as GPE-DV outcome scores were not accessible in the clinical registry for three participants. ††Reflects the number of closed treatment episodes on which process and outcome indicators are based
