Development and validation of a diverticular clinical score for symptomatic uncomplicated diverticular disease after acute diverticulitis in a prospective patient cohort.

ABSTRACT:

Background

Following an attack of acute diverticulitis (AD), many patients continue to suffer from a complex of symptoms, titled 'symptomatic uncomplicated diverticular disease (SUDD)'. To date, there is no validated clinical score for standardized assessment of patients with SUDD, thereby hampering the interpretation of observational studies and the conductance of clinical trials.We aimed to develop a validated SUDD clinical score.

Methods

Data from previous prospective study of patients after AD was used to devise the score's first version. Validation was first performed using a focus group of patients after AD SUDD who underwent a structured cognitive personal interview. Thereafter, the diverticular clinical score (DICS) was applied for a second validation cohort. DICS scores of validation cohort were compared with physicians' global assessment for disease severity and inflammatory markers.

Results

In DICS second validation using 48 patients prospectively recruited after AD SUDD, a correlation matrix demonstrated strong correlation between total questionnaire's score and the presence of elevated inflammatory markers (??=?0.84). Mean score in patients with elevated inflammatory markers compared with those without inflammation was 17.8 versus 6.2, respectively, p?ConclusionsPatients suffering from post-AD SUDD exhibit a wide range of symptoms. The newly developed DICS accurately and reproducibly quantitates SUDD-related symptom severity. The DICS may prove useful for monitoring SUDD in clinical practice and in research settings, as well as facilitating patient stratification and therapeutic decisions.

Project description:ObjectiveTo derive and validate an objective clinical prediction rule for the presence of uncomplicated ureteral stones in patients eligible for computed tomography (CT). We hypothesized that patients with a high probability of ureteral stones would have a low probability of acutely important alternative findings.DesignRetrospective observational derivation cohort; prospective observational validation cohort.SettingUrban tertiary care emergency department and suburban freestanding community emergency department.ParticipantsAdults undergoing non-contrast CT for suspected uncomplicated kidney stone. The derivation cohort comprised a random selection of patients undergoing CT between April 2005 and November 2010 (1040 patients); the validation cohort included consecutive prospectively enrolled patients from May 2011 to January 2013 (491 patients).Main outcome measuresIn the derivation phase a priori factors potentially related to symptomatic ureteral stone were derived from the medical record blinded to the dictated CT report, which was separately categorized by diagnosis. Multivariate logistic regression was used to determine the top five factors associated with ureteral stone and these were assigned integer points to create a scoring system that was stratified into low, moderate, and high probability of ureteral stone. In the prospective phase this score was observationally derived blinded to CT results and compared with the prevalence of ureteral stone and important alternative causes of symptoms.ResultsThe derivation sample included 1040 records, with five factors found to be most predictive of ureteral stone: male sex, short duration of pain, non-black race, presence of nausea or vomiting, and microscopic hematuria, yielding a score of 0-13 (the STONE score). Prospective validation was performed on 491 participants. In the derivation and validation cohorts ureteral stone was present in, respectively, 8.3% and 9.2% of the low probability (score 0-5) group, 51.6% and 51.3% of the moderate probability (score 6-9) group, and 89.6% and 88.6% of the high probability (score 10-13) group. In the high score group, acutely important alternative findings were present in 0.3% of the derivation cohort and 1.6% of the validation cohort.ConclusionsThe STONE score reliably predicts the presence of uncomplicated ureteral stone and lower likelihood of acutely important alternative findings. Incorporation in future investigations may help to limit exposure to radiation and over-utilization of imaging.Trial registrationwww.clinicaltrials.gov NCT01352676.
