Methods: Currently employed individuals reporting chronic heartburn were selected from US household mail survey participants. Worker pro- ductivity and absenteeism were measured using the validated Work Pro- ductivity and Activity Impairment Questionnaire for Patients with Symp- toms of Gastro-Oesophageal Reflux Disease (WPAI-GORD) and quality of life was measured using the validated Quality of Life in Reflux and Dyspepsia (QOLRAD) instrument. The worker productivity score (WPS), representing lost productivity due to GERD symptoms expressed as a percent of potential total productivity, was used as the overall measure of combined absenteeism and reduced productive time. QOLRAD scores were categorized into those with low, medium and high quality of life. Lower QOLRAD scores indicate that GERD symptoms have a greater impact on quality of life. The mean WPS score for each quality of life category was calculated. Higher WPS scores indicate that symptoms are reducing overall productivity to a greater degree. Using a chi-square, patients were compared on the proportion within each quality of life category reporting lost productivity. Results: A total of 1,025 employed individuals with GERD symptoms were interviewed. Those with reduced productivity were on average more likely to be younger (p 0.001) but were similarly distributed in gender and income to those without impaired productivity. There was an associ- ation between quality of life and worker productivity, revealing that re- duced quality of life was associated with reduced worker productivity (p 0.001). GERD sufferers with a low quality of life score had the highest mean WPS, (a 33% decrease in overall work productivity). Those with a medium quality of life score had a mean WPS of 14%, followed by a WPS of 2% for those with high quality of life. Patients in the lowest category of quality of life had the highest percent (90%) of respondents reporting reduced productivity followed by those in the middle category (63.8% of individuals). Reduced productivity was reported by 21.8% of individuals measured with the highest quality of life. Conclusions: Decreased quality of life due to GERD is strongly associated with reduced worker productivity. This observed association helps to validate self-reported measures of impaired worker productivity associated with GERD. Thus, improving symptoms and quality of life of employees with GERD may reduce the overall costs to employers related to reduced productivity. 882 Treatment patterns, clinical outcomes, and resource utilization associated with sessile colorectal lesions Jane E.

Schulman 2 *. 1 Gastroenterology, Duke University Medical Center, Durham, NC, United States; 2 Duke Clinical Research Institute, Durham, NC, United States; and 3 Boston Scientific, Natick, MA, United States. Purpose: Sessile colorectal polyps often present a diagnostic and thera- peutic challenge to the endoscopist. The goals of this study were to: (1) describe treatment patterns and clinical outcomes, (2) determine factors associated with referral to surgery, and (3) estimate healthcare resource use for patients with sessile colorectal lesions. Methods: Using endoscopic and surgical databases, all patients with sessile colon lesions treated at a single academic center between 1997 and 2000 were identified and their records reviewed. Patient demographic data included age, sex, and race; polyp data included size, location, and histol- ogy (lesions T2 or greater were excluded). Number and type of procedure, procedure and anesthesia times, hospital length of stay (LOS), and com- plications were recorded. Costs were estimated using the hospital’s cost- accounting system. Bootstrapped 95% confidence intervals (95% CI) were used to compare mean procedure and anesthesia times, and LOS. Multiple regression analysis was used to identify predictors of surgical referral. Results: 280 patients were eligible for analysis. Mean age was 67 years; 61% were 65. Mean polyp size was 1.3cm (range: 0.2-6.0cm); 85% were 2.0cm, and 44% were located in the left colon. Ten patients had malig- nant polyps. 34% had 2 procedures, and 7% had 3; procedure number increased with polyp size. The most common complications were: bleeding (2.5%), small bowel obstruction (1.4%), and infection (1%); 90% occurred post-operatively, the risk increasing with age and polyp size. 24% of polyps 1.1–2.0 cm and 68% of polyps 2.1–3.0 cm were eventually referred to surgery. Referral to surgery was associated with polyp size and the pres- ence of carcinoma (adjusted RR and 95% CI, 5.88 (4.19 –7.37) and 3.54 (1.58 – 4.74), respectively). All patients treated endoscopically were dis- charged the same day. Surgery procedures took 88 minutes longer than non-surgical procedures (95% CI, 74.43–102.42). Mean LOS for transanal surgery was 3.74 days, for open resection 7.14 days, and for laparoscopic resection 5.56 days. Mean total cost of treatment was $2,038 (range:$153- $14,837); open surgical resection was the most expensive ($6,165) fol- lowed by laparoscopic resection ($5,522); piecemeal polypectomy was the most expensive endoscopic treatment ($892). Conclusions: (1) More than a third of sessile colorectal lesions in this series required 2 procedures to complete the resection. (2) Number of procedures, complication risk, and referral to surgery increased with polyp size. (3) Resource utilization, complications, and costs were significantly higher in the surgically treated patients. 883 The impact of an educational program on health related quality of life in patients with gastroesophageal reflux disease Ricardo A.

Results: In the GERD education group, score for vitality and physical functioning improved over a three month period, (Vitality 10.5 to 12.1, Physical functioning 18.5 to 20). Scores for the general education group and for the no program group worsened over the three month period, (Gen. Ed Group: Vitality 12.6 to 11.7, Physical functioning 23 to 19; No Program Group: Vitality 10.3 to 9.8, Physical functioning 19 to 14.8). There was no significant difference in medication changes between the groups. Conclusions: A well-structured educational program for GERD patients may improve health related quality of life.
