A patient-centered framework for health systems engineering in gastroenterology: improving inpatient colonoscopy bowel preparation.

BACKGROUND: Inpatient colonoscopy bowel preparation (ICBP) is frequently inadequate and can lead to adverse events, delayed or repeated procedures, and negative patient outcomes. Guidelines to overcome the complex factors in this setting are not well established. Our aims were to use health systems engineering principles to comprehensively evaluate the ICBP process, create an ICBP protocol, increase adequate ICBP, and decrease length of stay. Our goal was to provide adaptable tools for other institutions and procedural specialties. METHODS: Patients admitted to our tertiary care academic hospital that underwent inpatient colonoscopy between July 3, 2017 to June 8, 2018 were included. Our multi-disciplinary team created a protocol employing health systems engineering techniques (i.e., process mapping, cause-effect diagrams, and plan-do-study-act cycles). We collected demographic and colonoscopy data. Our outcome measures were adequate preparation and length of stay. We compared pre-intervention (120 ICBP) vs. post-intervention (129 ICBP) outcomes using generalized linear regression models. Our new ICBP protocol included: split-dose 6-L polyethylene glycol-electrolyte solution, a gastroenterology electronic note template, and an education plan for patients, nurses, and physicians. RESULTS: The percent of adequate ICBPs significantly increased with the intervention from 61% pre-intervention to 74% post-intervention (adjusted odds ratio of 1.87, p value = 0.023). The median length of stay decreased by approximately 25%, from 4 days pre-intervention to 3 days post-intervention (p value = 0.11). CONCLUSIONS: By addressing issues at patient, provider, and system levels with health systems engineering principles, we addressed patient safety and quality of care provided by improving rates of adequate ICBP.

Endoscopic sleeve gastroplasty versus high-intensity diet and lifestyle therapy: a case-matched study.

BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) is a safe and effective minimally invasive bariatric procedure. This study compared weight loss in patients undergoing ESG with that of matched patients undergoing high-intensity diet and lifestyle therapy (HIDLT). METHODS: In this case-matched study, patients were matched 2/3:1 (HIDLT/ESG) by age, sex, and body mass index (BMI). One hundred five patients (30 men) who underwent ESG + low-intensity diet and lifestyle therapy (LIDLT) between 2016 and 2018 were compared with 281 patients (92 men) who underwent HIDLT at the Johns Hopkins Medical Institutions from 2013 to 2014. Weight was evaluated 1, 3, 6, and 12 months after beginning HIDLT or post-ESG to determine the mean percent total body weight loss (%TBWL). RESULTS: Mean age across both cohorts was 48.0 ± 12.1, and baseline BMI was 40.0 ± 7.7 kg/m2. In multivariable analysis controlling for age, sex, and baseline BMI, the mean %TBWL at 1, 3, 6, and 12 months was significantly higher in patients undergoing ESG than matched patients undergoing HIDLT. Specifically, at 3 months, the mean %TBWL in the ESG cohort was 14.0% compared with 11.3% in the HIDLT cohort (P <.011), and at 12 months the mean %TBWL in the ESG cohort was 20.6% versus 14.3% in the HIDLT cohort (P < .001). ESG patients with baseline BMI ≤40 kg/m2 continued to show significantly greater %TBWL than those of the same BMI group in the HIDLT group at 1, 3, 6, and 12 months after intervention (3 months, coefficient = 3.43 [P < .001]; 12 months, coefficient = 8.14 [P < .001]). CONCLUSIONS: Through 12 months of follow-up, patients who underwent ESG achieved significantly greater weight loss than patients enrolled in HIDLT. ESG appears to be a valuable alternative for patients who experience difficulty complying with HIDLT.

Early Hemoconcentration Is Associated With Increased Opioid Use in Hospitalized Patients With Acute Pancreatitis.

OBJECTIVES: Opioids are commonly required for abdominal pain in hospitalized patients with acute pancreatitis (AP). The factors associated with increased opioid requirements are unknown. METHODS: The medical records of adult inpatients with AP from 2006 to 2016 were reviewed. Patients with chronic pancreatitis, psychiatric comorbidities, intubation, chronic opioid, and illicit drug use were excluded. The total quantity of opioids required during the first 7 days of hospitalization was converted to oral morphine equivalents (OME), divided by the number of days opioids were required to obtain the mean OME per day(s) of treatment (MOME). Multiple regression analysis was performed to identify factors associated with MOME. RESULTS: A total of 267 patients were included. The mean (standard deviation) age was 46.9 (13.9) years and 56% were males. The most common etiology was alcohol (55.4%). The mean (standard deviation) MOME was 59.1 (54.5) mg. Although age (P = 0.008), black race (P = 0.004), and first episode of AP (P = 0.049) were associated with a lower MOME, early hemoconcentration (hematocrit ≥44%) (P < 0.001) was associated with an increased MOME. CONCLUSIONS: Early hemoconcentration is associated with an increased opioid requirement in hospitalized patients with AP. The impact of fluid therapy in these patients merits prospective study.
