BACKGROUND: Characterization of the prognostic variables for persistent @entity9 (PNP) remains incomplete despite multiple articles addressing this topic. To provide more insight into the recovery and prognosis of @entity9 , high-quality data are required that provide information about the predictors that contribute to the development of PNP. OBJECTIVE: To determine the methodological quality of studies about predictors for PNP and to summarize findings of predictors found in high-quality studies. STUDY DESIGN: A systematic review. SETTING: VU University Medical Center, Amsterdam, The Netherlands. METHODS: Studies were identified by searching the electronic databases PubMed, Embase, and Cochrane Library. Methodological quality of each article was independently assessed by 2 reviewers. RESULTS: Forty-six relevant studies were identified, classified into 4 different @entity9 ( @entity9 )-syndromes: @entity14000 (n = 35), @entity158 and sciatica (n = 3), postsurgical @entity158 (n = 6), and other types of @entity9 (n = 2). Seven studies were of high quality. The 3 high-quality studies found for PHN reported male gender, older age, smoking, @entity130 at the site of lesion, missed antiviral prescriptions, higher @entity12761 severity, higher rash severity, more neuropathic characteristics, @entity1910 , and a lower health status as predictors for PNP. For persistence of @entity158 one high-quality study reported negative outcome expectancies, @entity158 -related fear of movement, and passive @entity158 coping as predictors for PNP. @entity458 , @entity12761 , @entity0 surgery, higher body mass index, area of secondary @entity1931 , neuropathic characteristics, @entity1183 , and @entity17401 were found to be predictive for postsurgical @entity158 in 3 high-quality studies. LIMITATIONS: Some publications may have been missed during literature search. The low-quality of the studies could be the result of an incomplete description of their methods. CONCLUSIONS: High-quality studies mainly assessed factors related to disease functions and structures. Due to shortcomings in methodological quality and limited areas of predictor selection, there is a need for high-quality studies focusing on predictor measurement, statistical analysis and the use of a standardized set of predictors.
