A Nation-Wide Study of Prevalence and Risk Factors for Fecal Impaction in Nursing Homes

Background There are no existing studies that provide data regarding the epidemiology of, and risk factors for, fecal impaction, either in the general population or in any sub-group of people. Objective Estimate the prevalence of and factors associated with fecal impaction on a representative sample of the institutionalized elderly population. Design Two-phase study. Phase 1: pilot study validating the methodology in which all residents of a single nursing home participated. Phase 2: national multi-center cross-sectional study. Setting 34 randomly selected nursing homes. Measurements The presence of fecal impaction and associated factors were evaluated using three different tools: data collected from medical records; a self-completion questionnaire filled out by the subjects or a proxy; and a rectal examination. Subjects Older subjects living in nursing homes. Results The prevalence of chronic constipation was 70.7% (95%CI: 67.3–74.1%), of which 95.9% of patients were properly diagnosed and 43.1% were properly controlled. The prevalence of FI according to patient history was 47.3% (43.6–51.0%) and 6.6% (4.7–8.5%) according to rectal examination. Controlled constipation (OR: 9.8 [5.2–18.4]) and uncontrolled constipation (OR: 37.21 [19.7–70.1]), the number of medications (OR: 1.2 [1.1–1.3]), reduced functional capacity (OR: 0.98 [0.97–0.99]) and the occasional use of NSAIDs were independent risk factors for fecal impaction. Conclusions Constipation affects more than 70% of people living in nursing homes. Although it is properly diagnosed in more than 95% of cases, the disease is only controlled in less than 50%. Constipation, especially when not controlled, is the most significant risk factor leading to fecal impaction, which is prevalent in almost 50% of this population.

Translation, cultural adaptation and validation of a Spanish version of the Irritable Bowel Syndrome Severity Score

BACKGROUND the Irritable Bowel Syndrome Severity Score (IBSSS) is a questionnaire only available in English that classifies IBS patients according to the severity of their symptoms and can be used to guide and monitor the treatment. AIMS to adapt and validate into Spanish the English version of the IBSSS questionnaire. METHODS the Spanish version of the questionnaire was obtained through a process of translation-evaluation of the comprehensibility and back translation. In a later phase we evaluated the applicability(n = 15), reproducibility (n = 31) and sensitivity to change (n = 40) of the Spanish version of the questionnaire. Finally we evaluated an alternative version of the ISBSS using a numerical scoring system instead of the original analog visual scale (n = 40). RESULTS the Spanish version of the IBSSS showed an excellent reproducibility (r = 0.81 for global score) and an adequate sensitivity to change: a decrease of 45 points or more identified worsening of IBS with a 70.6% sensitivity and 87.5% specificity; an increase of 45 points or more identified improvement of IBS with a 85.7% sensitivity and 87.5% specificity. The severity score was practically the same regardless of the scoring system used (r = 0.96). CONCLUSIONS the Spanish version of the IBSSS is a reproducible tool that is able to identify relevant changes over the course of the disease. The use of a numerical scoring system is a valid alternative to the visual scale that improves the applicability of the questionnaire to situations when the written communication is limited or not possible.

Is the reflux disease questionnaire useful for identifying GERD according to the Montreal definition

BackgroundScales for aiding physicians diagnose gastro-oesophageal reflux disease (GERD) have not been evaluated in terms of their ability to discriminate between troublesome symptoms (TS) and non-troublesome symptoms (NTS). Our objective is to evaluate the ability of the Reflux Disease Questionnaire (RDQ) to identify GERD according to referral of TS, in patients without previous proton pump inhibitor (PPI) treatment and in patients on PPI treatment.MethodsPatients consulting physicians because of heartburn or acid regurgitation were recruited at 926 primary-care centres in Spain. They were asked to complete several questionnaires including the RDQ, and to define which of their symptoms were troublesome. Information on drug treatment was collected by the physician. We performed a receiver operating characteristic (ROC) curve analysis to ascertain the RDQs optimum cut-point for identifying TS.Results4574 patients were included, 1887 without PPI and 2596 on PPI treatment. Among those without PPI treatment, 1722 reported TS. The area under the curve (AUC) was 0.79 for the RDQ, and the optimum RDQ cut-point for identifying TS was 3.18 (sensitivity, 63.2%; specificity, 80.2%). A total of 2367 patients on PPI treatment reported TS, and the optimum RDQ cut-off value was 3.06 (sensitivity, 65.4%; specificity, 71.8%).ConclusionsAn RDQ score higher than 3 shows good sensitivity and specificity for differentiating TS from NTS among patients without PPI or on PPI treatment. The RDQ is useful in primary care for diagnosis of GERD based on the Montreal definition.

Advantages of early cholecystectomy in clinical practice of a terciary care center

BACKGROUND Despite a number of studies show the superiority of early over delayed cholecystectomy in the treatment of acute cholecystitis, there is still controversy over the time for intervention. This study aimed to assess the use of early versus delayed cholecystectomy for the treatment of acute cholecystitis in terms of complications, conversion to open surgery and mean hospital stay. METHOD We collected patients with acute cholecystitis treated at a referral center for a year, and retrospectively analyzed the chosen therapeutic approach, the percentage of conversion of early cholecystectomy to open surgery, appearance of surgical complications, and mean hospital stay. RESULTS The study included 117 patients, 44 women and 73 men, who had a mean age of 67.36+/-15.74 years. Early cholecystectomy was chosen in 31 (26.5%) and delayed cholecystectomy in 74 patients (63.2%). Of the 74 patients, 28 (37.8%) required emergency performance of delayed cholecystectomy, and 19 (25.7%) had not undergone surgery by the end of the study. While no differences were observed between early and delayed cholecystectomy in terms of surgical complications and conversion to open surgery, mean hospital stay was nevertheless significantly shorter in the early versus the delayed cholecystectomy group (8.32+/-4.98 vs 15.96+/-8.89 days). CONCLUSION Under the routine working conditions of a hospital that is neither specially dedicated to the surgical treatment of acute cholecystitis nor provided with specific management guidelines, early cholecystectomy can reduce the hospital stay without increase of the conversion rate or complications.

Validation of a questionnaire for assessing fecal impaction in the elderly: impact of cognitive impairment, and using a proxy

BackgroundStudies on the epidemiology of fecal impaction are limited by the absence of a valid and reliable instrument to identify the condition in the elderly. Our aim is to validate a questionnaire for identifying fecal impaction in the elderly and to assess the impact of cognitive impairment and the aid of a proxy on its reliability.MethodsWe developed a 5 questions’ questionnaire. The questionnaire was presented to twenty doctors to test its face validity. Feasibility was pre-tested with ten non institutionalized subjects who completed the questionnaire twice, once alone or with the help of a proxy, and another along with the researcher.For the validation of the questionnaire all residents in a single nursing-home were invited to participate, allowing the self-decision of using a proxy. Medical records of all subjects were abstracted without knowledge of subjects’ answers and agreement between fecal impaction according to self-reported and medical records analyzed. Physical impairment was measured with the Barthel’s test and cognitive impairment with the mini-mental test.ResultsIn the face validity only minor changes in wording were suggested. In the feasibility pre-test all subjects were able to understand and complete the questionnaire and all questions were considered appropriate and easily understandable.One-hundred and ninety-nine of the 244 residents participated in the study (mean age 86,1 ± 6,6). One hundred and forty two subjects understood all questions; not understanding them was inversely associated with cognitive impairment score (aOR: 0.86; 95% CI: 0.82-0.91). One hundred and sixty decided to use a proxy; the use of a proxy was inversely associated with educative level (0.13 (0.02-0.72), minimental’s score (0.85; 0.76-0.95) and Barthel’s score (0.96; 0.94-0.99). Agreement between medical records and self-completed questionnaire was 85.9% (kappa 0.72 (0,62- 0,82). Disagreement was unrelated to education and cognitive impairment.ConclusionsOur simple questionnaire is reliable for identifying fecal impaction in the elderly by self-report. Limitation imposed by cognitive impairment is minimized with the aid of a proxy.

The Prevalence of Fecal Impaction in Nursing Homes: A Pilot Study

[48], fistula [32], stricture [3]) 246 occurred within 7 days and 277 within 30 days, while 209 occurred 30 or more days after the incident episode. The risk of complications was associated with age (hazard ratio [95% CI per decade] 1.14 [1.07, 1.21]), but not gender or time period. The estimated overall survival at 20 years (49%) did not differ significantly (p=0.76) from that expected for the MN white population generally. Conclusions. This population-based study demonstrates that the incidence of diverticulitis has increased by almost 50%between 1990-1997 and 2000-2007. Contrary to current concepts, complications were more frequent in older than younger people but overall survival was not affected. Further studies are necessary to identify patients at the greatest risk of diverticulitis complications. Diverticulitis Summary Table
