Prospective assessment of Cleveland Global Quality of Life (CGQL) as a novel marker of quality of life and disease activity in Crohn's disease

Motivational interviewing to change quality of life for people with chronic heart failure: A randomised controlled trial

BACKGROUND

Patients with chronic heart failure have a reduced quality of life due in part to their limited range of physical activity and independence.

OBJECTIVES

The paper examines whether a physical activity 'lifestyle' intervention, based on motivational interviewing, will improve quality of life at five months from baseline, compared with conventional treatment.

METHODS

Sixty older patients with chronic heart failure were randomly assigned to either a 'standard care', 'motivational interviewing' or 'both' treatment groups for five months in 2002. The primary outcome measures were the Medical Outcomes Short Form-36 Health Survey, the disease-specific Minnesota Living with Heart Failure questionnaire and the Motivation Readiness for Physical Activity scale.

RESULTS

There were non-significant differences between the groups at baseline for age, coronary risk factors, severity of chronic heart failure, ejection fraction, specific laboratory tests, length of hospitalisation, medication and social support. Following treatment there was a significant increase (p<0.05) for three of the dimensions of the health survey in the 'motivational interviewing' group. All groups improved their scores (p<0.05) on the heart failure questionnaire. Over the five month period there was a general trend towards improvements in self-efficacy and motivation scores.

CONCLUSIONS

This study has demonstrated that a 'motivational interviewing' intervention, incorporating behaviour change principles to promote physical activity, is effective in increasing selected aspects of a general quality of life questionnaire and a disease-specific quality of life questionnaire. Thus a 'motivational interviewing' approach is a viable option compared with traditional exercise programming. It is important to test these motivational interviewing interventions more widely, especially to match individuals to treatments.

Quality of life of patients with ulcerative colitis: past, present, and future

Quality of life (QoL) is vitally important to patients with chronic illnesses such as ulcerative colitis (UC) and has been assessed in observational, cross-sectional, and cohort studies. However, relatively few clinical trials have evaluated the QoL of patients with UC. Recently, greater availability of the necessary tools has facilitated the undertaking of studies showing that QoL of patients with UC is reduced significantly compared with that of the general population. Studies using disease-specific instruments have identified disease severity as the strongest predictor of QoL, with other disease-related predictors including type of medical or surgical treatment and the efficacy, tolerability, and acceptability to patients of particular types of medical or surgical treatments. Other factors, such as comorbid medical or psychosocial problems and adherence to treatment, also affect QoL. Combined use of generic and disease-specific instruments in clinical trials can ensure that all clinically relevant unexpected events (generic instrument) and important improvement or deterioration (disease-specific instrument) are captured. For accurate outcomes assessment, the use of comprehensively validated instruments is critical. The need for the development and evaluation of new instruments will be determined by the mechanisms and targets of novel therapies. Ultimately, QoL assessment of effective therapies will play a strong role in pharmacoeconomic evaluations, providing health policy makers with the evidence to support the treatments that can most effectively normalize QoL through complete symptom resolution, minimal side effects, and convenient administration.

Postoperative complications have little influence on long-term quality of life in Crohn's patients

PURPOSE

The purpose of the study was to determine the influence of postoperative complications on long-term quality of life in patients after abdominal operations for Crohn's disease.

MATERIALS AND METHODS

From 1996 to 2002, 305 Crohn's patients underwent abdominal surgery, and 66 patients developed postoperative complications. Quality of life was studied using a standardized questionnaire and four quality of life instruments. Sixty-six Crohn's patients with uneventful postoperative course matched for age, and follow-up time served as controls.

RESULTS

Forty-eight patients (81%) in the complication group (32 major and 16 minor) and 43 patients (75%) in the control group answered the questionnaire. Postoperative follow-up time was 42 (10-94) and 41 months (13-94; median (range)). Quality of life was comparable between groups, except on the subscale "physical functioning" of the Short-form 36 on which patients with minor and major complications showed impaired quality of life compared to controls (67+/-6, 69+/-4, and 84+/-2%; mean+/-standard error of the mean; both p<0.05 vs controls). The incidence of Crohn's disease-related symptoms at follow-up was unaffected by complications (minor 63%, major 56% vs controls 70%; both not significant).

CONCLUSION

Postoperative complications after abdominal operations for Crohn's disease do not impair long-term quality of life in general but may affect specific dimensions of quality of life like patients' physical function.

Long-term quality of life in patients with Crohn's disease and perianal fistulas: influence of fecal diversion

PURPOSE

Symptomatic perianal fistulas impair quality of life in patients with Crohn's disease. Fecal diversion improves symptoms but may impair quality of life. This study was designed to compare long-term quality of life in patients with Crohn's disease with symptomatic perianal fistulas who were treated with or without fecal diversion.

METHODS

From 1996 to 2002, perianal fistulas were treated in 116 patients with Crohn's disease. A questionnaire, including four quality of life instruments, was mailed to each patient (Short-Form General Health Survey, Gastrointestinal Quality of Life Index, Cleveland Global Quality of Life Score, Short Inflammatory Bowel Disease Questionnaire).

RESULTS

Questionnaires were returned by 77 of 116 patients (66 percent). Thirty-four of these patients had undergone fecal diversion, whereas 43 had not. Median follow-up was 49 (range, 18-97) months in diverted and 44 (range, 14-98) months in undiverted patients (not significant). In the diverted group, 44 percent complained of Crohn's disease-related symptoms, which was less compared with 79 percent in undiverted patients (P < 0.05). Diverted patients achieved 68 +/- 1 percent of the maximum possible score on the Gastrointestinal Quality of Life Index compared with 60 +/- 2 percent in undiverted patients (mean +/- standard error of the mean; P < 0.001); diverted patients scored better on the subscale "gastrointestinal symptoms" of the Gastrointestinal Quality of Life Index (81 +/- 1 percent vs. 67 +/- 2 percent; P < 0.001). There was no difference in the Short Inflammatory Bowel Disease Questionnaire between diverted and undiverted patients except for the subscale "bowel function" (91 +/- 2 percent vs. 76 +/- 2 percent; P < 0.0001). No difference in quality of life was detected by the Short-Form General Health Survey and Cleveland Global Quality of Life Score.

CONCLUSIONS

In the investigated population of patients with Crohn's disease, quality of life seems to be similar or potentially superior in diverted patients suffering from perianal fistulas compared with undiverted patients. A diverting stoma, therefore, may improve quality of life in patients with severe perianal Crohn's disease.

Crohn's disease: systematic review of assessment of disease severity and its relevance to surgery

BACKGROUND

The aims of treatments for Crohn's disease are symptom control by medical or surgical means and improvement in health-related quality of life (HRQOL). A wide number of classification systems, instruments of disease activity measurement (DAM) and HRQOL are available, but few are used in routine surgical practice.

OBJECTIVE

To review the validity of DAM and HRQOL instruments and their applicability to surgically treated patients.

METHOD

A systematic literature search was undertaken to identify these instruments. Qualifying articles were used to determine the construct, content and criterion validity of the instruments identified with respect to surgically treated patients.

RESULTS

Thirteen disease activity indices and 11 HRQOL assessment tools were identified. Construct validity was demonstrated throughout but concerns of content and criterion validity were noted.

CONCLUSION

None of the current disease activity or HRQOL tools can be used without potential bias in a trial of surgical vs medical therapy as the items included favour the outcomes experienced following medical therapy. A more balanced assessment tool in the setting of a multidisciplinary trial is needed.

Clinical features and quality of life in patients with different phenotypes of Crohn's disease of the ileal pouch

PURPOSE

Crohn's disease of the pouch can occur in patients with colectomy and ileal pouch-anal anastomosis performed for ulcerative colitis. The clinical features of inflammatory, fibrostenotic, and fistulizing Crohn's disease have not been characterized.

METHODS

A total of 73 eligible patients with Crohn's disease of the pouch, who were seen in the Pouchitis Clinic, were enrolled: 25 with inflammatory Crohn's disease, 17 with fibrostenotic Crohn's disease, and 31 with fistulizing Crohn's disease. The clinical phenotypes of Crohn's disease were based on a combined assessment of clinical, endoscopic, radiographic, and histologic features. Clinical symptoms, endoscopic and histologic features, and health-related quality-of-life scores were assessed.

RESULTS

Demographic and clinical features, including preoperative and postoperative parameters, were similar between the three phenotypes of Crohn's disease of the pouch. The use of nonsteroidal anti-inflammatory drugs, neuropsychiatric drugs, antidiarrheal agents, and Crohn's disease medicines was not different between the three groups. Predominant symptoms, as expected, were significantly different between the three phenotypes: diarrhea and/or pain in 92 percent of patients with inflammatory Crohn's disease, obstructive symptoms in 64.7 percent of patients with fibrostenotic Crohn's disease, and fistular drainage in 51.6 percent of those with fistulizing Crohn's disease (P < 0.0001). There was no statistical difference in quality-of-life scores between the three phenotypes, adjusted for disease activity. There was no significant correlation between quality-of-life and symptom scores in any of the three groups. Although not statistically significant, patients with fistulizing Crohn's disease (16.1 percent) tended to have an increased risk for pouch failure compared with inflammatory (8 percent) or fibrostenotic (5.9 percent) Crohn's disease.

CONCLUSIONS

Predominant symptoms were different in clinical phenotypes of Crohn's disease. Each of the three phenotypes of Crohn's disease similarly affected quality-of-life. Fistulizing Crohn's disease may be associated with a higher risk for pouch failure.

Health-related quality of life after ileocolonic resection for Crohn's disease: long-term results

BACKGROUND

Crohn's disease (CD) is a chronic illness that interferes with the daily life of those affected. The aim of the present study was to evaluate long-term health-related quality of life (HRQL) outcome and its clinical predictors in CD patients who have had ileocolonic resection.

METHODS

Ninety-seven CD patients, with a mean follow-up of 47.1 months (95% CI, 40.7-53.5 months) after ileocolonic resection, were interviewed by telephone and responded to the generic Cleveland Global Quality of Life (CGQL) questionnaire, and 63 of them also agreed to come to our outpatient clinic to have a Crohn's Disease Activity Index (CDAI) assessment and blood test and to answer the disease-specific Padova Inflammatory Bowel Diseases Quality of Life (PIBDQL) questionnaire. Control groups also were enrolled.

RESULTS

The CGQL scores of the 97 CD patients were similar to those of 69 healthy controls. Only the item on current quality of health was scored significantly lower by patients with CD. In contrast, the PIBDQL item and total scores of the CD patients were all significantly lower than those of the respective healthy controls (P < 0.05). Multivariate analysis showed that the CGQL and PIBDQL scores both had a strong linear relationship with number of daily stools and with CDAI score (P < 0.05).

CONCLUSIONS

Despite CD patients who have undergone ileocolonic resection having an apparently normal quality of life with a good energy level, as shown by the CGQL, their long-term HRQL is still affected by a significantly impaired quality of health. In fact, the PIBDQL questionnaire showed significant impairment of bowel and systemic symptom domains with important consequences for emotional and social functions. HRQL seems to be significantly related only to current disease activity.

Quality of life after proctocolectomy with ileoanal anastomosis for patients with ulcerative colitis

Ulcerative colitis, a chronic inflammatory disease of the rectal and colonic mucosa, affects approximately 250,000 to 500,000 people in the United States, with 30% to 40% of patients requiring some form of surgical intervention during the course of their disease. The predominant reason for total proctocolectomy is for symptoms refractory to currently available medical therapy. Less common reasons are dysplasia or cancer. The goal of colectomy is to prevent recurrence of systemic inflammatory disease. Consequently, surgery with total proctocolectomy and creation of an ileal J-pouch-anal anastomosis has become the procedure of choice for many patients without other therapeutic options. Health-related quality of life (QOL) in patients with severe ulcerative colitis is so poor that, after ileal J-pouch-anal anastomosis, QOL is considered to improve in most clinical studies (8 studies, improved QOL; 1 study, no change; 1 study, QOL worse than general population). However, QOL and bowel function after such surgery cannot be considered "normal" in all patients, because a substantial number still have problems with urgency, leakage, nocturnal soiling, sexual dysfunction, and pouchitis, and some require conversion to a permanent ileostomy after ileal J-pouch-anal anastomosis failure. Thus, despite the availability of ileal J-pouch-anal anastomosis, surgery does not always restore all aspects of QOL to normal.

Relevance of the phenotypic characteristics of Crohn's disease in patient perception of health-related quality of life

BACKGROUND

Crohn's disease (CD) has a negative impact on patients' perception of health. Several factors, such as disease activity, influence HRQOL impairment. However, the effect of the phenotypic CD characteristics recognized in the Vienna classification on health-related quality of life (HRQoL) remains unknown.

METHODS

HRQOL was measured in CD patients using three questionnaires: the Spanish version of the Inflammatory Bowel Disease Questionnaire (IBDQ-36), the Psychological General Well-Being Index (PGWBI), and the EuroQol.

RESULTS

One hundred ninety-eight CD patients were included. Scores for the IBDQ-36, PGWBI, and EuroQol dimensions did not differ according to age at diagnosis (177 patients under 40 yr and 21 over 40 yr), disease location (53 in terminal ileum, 62 in colon, 72 in ileocolon, and 11 in upper gastrointestinal tract) or disease behavior (99 nonstricturing-nonpenetrating, 32 stricturing, and 67 penetrating). Multivariate analysis identified as significant independent variables for worse HRQoL: female sex (t: -3.70), higher number of relapses per year (t: -2.71), and worse clinical disease activity (t: -7.82). None of the three Vienna variables reached statistical significance.

CONCLUSIONS

HRQoL impairment in CD patients is independent of the clinical variables established in the Vienna classification for phenotypic type of disease.

Review article: psychosocial factors in the quality of life of patients with inflammatory bowel disease

Information on quality of life in inflammatory bowel disease is limited. Despite the clear importance of this topic to patients, quality of life measurement is seldom undertaken in day-to-day management of patients or included in clinical trials. Although previous reviews have dealt with quality of life, the area of psychosocial functioning has not been specifically addressed. The aim of this study was to review the psychosocial factors affecting quality of life in patients with inflammatory bowel disease, using an electronic search of MEDLINE, EMBASE, CINAHL and psycINFO. Of the 751 articles identified by the search, 107 were considered relevant and included in the review. A number of psychosocial factors appear to be important, including gender, socioeconomic status, ethnicity and perceived stress. To improve the quality of life in patients with inflammatory bowel disease, clinicians' attention needs to be drawn towards this subject, with an awareness of those patient groups more vulnerable to impaired quality of life. These identified variables also represent important factors, which should be adjusted for when conducting research into quality of life in these patients.

Dynamic color Doppler sonography of intestinal wall in patients with Crohn disease compared with healthy subjects

OBJECTIVE

Chronic inflammatory bowel diseases are characterized by inflammatory hyperperfusion of the intestinal wall in affected bowel segments. We applied a novel method to quantify color Doppler signals dynamically along a complete heart cycle inside the bowel wall. The aim was to describe bowel wall perfusion in Crohn disease patients in comparison with healthy probands and to compare a conventional activity index (Pediatric Crohn Disease Activity Index) with perfusion measurements as an indicator of inflammatory activity.

METHOD

Color Doppler sonographic videos of bowel wall perfusion from 34 healthy children (aged 5 to 18 years) and from 14 patients with Crohn disease (aged 8.2 to 15.9 years) were recorded under defined conditions. Perfusion signals (color hue, color area) were automatically measured inside the bowel wall. Specific tissue perfusion was calculated as mean flow velocity of a region of interest during one full heart cycle. Bowel wall perfusion was compared using the Pediatric Crohn Disease Activity Index in 12 patients.

RESULTS

Specific bowel wall perfusion was significantly elevated in bowel segments of Crohn disease patients compared with healthy subjects (P < 0.001). Specific flow in small bowel was 0.025 cm/s in healthy probands and 0.095 cm/s in patients with Crohn disease, whereas large bowel wall perfusion of 0.012 cm/s in healthy probands clearly differed from 0.082 cm/s in patients with Crohn disease. No differences of perfusion between moderate and high Pediatric Crohn Disease Activity Index levels could be demonstrated despite a weak significant overall correlation.

CONCLUSION

The new method of dynamic, automatic noninvasive perfusion quantification is useful to describe local inflammatory activity in bowel segments affected by Crohn disease and adds new information to activity evaluation by Pediatric Crohn Disease Activity Index. Specific wall perfusion in intestines of Crohn patients is significantly elevated and reaches up to sevenfold intensity compared with healthy subjects.

Analysis of the outcome of ileal pouch-anal anastomosis in patients with Crohn's disease

PURPOSE

Ileal pouch-anal anastomosis has come to represent the procedure of choice for patients requiring surgery for mucosal ulcerative colitis. In contrast, a proven diagnosis of Crohn's disease is generally held to preclude ileal pouch-anal anastomosis. However, patients with ileal pouch-anal anastomosis for apparent mucosal ulcerative colitis who are subsequently found to have Crohn's disease have a variable course. We reviewed our experience in this scenario to determine whether selected patients with Crohn's disease may be candidates for ileal pouch-anal anastomosis.

METHODS

A retrospective review of the prospectively maintained ileal pouch-anal anastomosis database was undertaken to identify patients with a diagnosis of Crohn's disease after ileal pouch-anal anastomosis. Clinical outcome and quality-of-life data were obtained from the database and chart review. End points were the development of recrudescent Crohn's disease, pouch failure, and quality of life and functional outcome at the time of data collection. Differences between groups were calculated using the chi-squared test. Cumulative incidence of recrudescent Crohn's disease and pouch loss were calculated by the Kaplan-Meier method. Factors predictive of development of recrudescent Crohn's disease and pouch loss were examined by univariate analysis.

RESULTS

Sixty patients (32 females; median age, 33 (range, 15-74) years) who underwent ileal pouch-anal anastomosis for mucosal ulcerative colitis subsequently had that diagnosis revised to Crohn's disease. Median follow-up of all patients was 46 (range, 4-158) months at time of data collection by which time 21 patients (35 percent) had developed recrudescent Crohn's disease. No pre-ileal pouch-anal anastomosis factors examined were predictors of the development of recrudescent Crohn's disease on univariate analysis. Median follow-up of the latter group was 63 (range, 0-132) months from time of diagnosis, by which time six patients underwent pouch excision and another patient was permanently defunctioned. The overall pouch loss rate for the entire cohort was 12 percent and 33 percent for those with recrudescent Crohn's disease. Median daily bowel movements in those with ileal pouch-anal anastomosis in situ at the time of data collection was 7 (range, 3-20), with 50 percent of patients rarely or never experiencing urgency and 59 percent reporting perfect or near perfect continence. Median quality of life, health, and happiness scores were 9.9 and 10 of 10.

CONCLUSIONS

The secondary diagnosis of Crohn's disease after ileal pouch-anal anastomosis is associated with protracted freedom from clinically evident Crohn's disease, low pouch loss rate, and good functional outcome. Such results only can be improved by the continued development of medical strategies for the long-term suppression of Crohn's disease. These data support a prospective evaluation of ileal pouch-anal anastomosis in selected patients with Crohn's disease.

Quality of life improves within 30 days of surgery for Crohn's disease

BACKGROUND

The effect of surgery on quality of life (QOL) in the early postoperative period is important in Crohn's disease because of the multiple surgical procedures that patients undergo and the acute QOL benefits that might occur as a result of modifications of medical treatment. Earlier studies of the effect of surgery on QOL have been retrospective and assessed changes 3 to 24 months after surgery. This study prospectively assesses the effect of surgery on QOL in the early postoperative period.

STUDY DESIGN

Patients requiring surgical management of sequelae of Crohn's disease were obtained from a prospectively entered database including data on QOL. Preoperative and 30-day postoperative QOL were determined in 82 patients using Cleveland Global Quality of Life (CGQL) scores (range from 0 [worst] to 10 [best possible] QOL). Preoperative and postoperative scores were compared using a paired t-test to determine the significance of any change in QOL after surgery. The effect of other variables on change in QOL after surgery was assessed using the t-test or analysis of variance. Multifactor analysis of variance was used to assess the effect of several independent variables.

RESULTS

Eighty-two patients (41 women) of 142 patients who had had surgery (58%) had complete preoperative and 30-day postoperative scores. The incidence of complications was 23% (11% were major). There was a significant improvement in QOL 30 days after surgery as measured by CGQL (0.6 +/- 0.2 preoperative to 0.7 +/- 0.2 postoperative; mean +/- SD; p < 0.001). The mean preoperative CGQL was 0.56 +/- 0.24 and the mean improvement was 0.11 +/- 0.20 toward a better QOL. Female patients (p < 0.05) and those who did not develop complications within 30 days of surgery (p < 0.05) had a significantly greater improvement in CGQL after surgery than other groups. No other factor was predictive of improved outcomes.

CONCLUSIONS

QOL as measured by CGQL improves early after surgery (30 days postoperatively). Improvement in CGQL is greater in female patients and patients who do not develop complications in the postoperative period. It is not affected by other patient characteristics, nature of disease, indication, or procedure performed. Most patients who undergo surgery for Crohn's disease feel that surgery has helped them and would undergo surgery again.
