Abstract BackgroundObstructive sleep apnea (OSA) is a frequent comorbid condition in patients with type 2 diabetic (T2DM). Concomitant OSA is associated with a detrimental impact on metabolic control. Both OSA and T2DM independently lead to increased cardiovascular disease and mortality. The impact of OSA on the acceleration of organ dysfunction leading to increased healthcare utilization is unknown.MethodsThis is a retrospective case–control cohort study, a secondary analysis utilizing a nationwide dataset. Patients who underwent elective surgical procedures from 2009 to 2014 were identified. Among these patients, we compared patients with obstructive sleep apnea and those without obstructive sleep apnea. Exact 1:1 matching was performed based on similar characteristics such as age, sex, geographic location, surgical facility environment, performing surgeon, and severity of illness during hospitalization. The subgroup of patients with T2DM with or without OSA was analyzed for post-discharge hospital admissions, intensive care unit (ICU) admissions, emergency room (ER) visits, and outpatient visits.ResultsAmong 47,719 matched patients of the initial study, this subgroup included 4,567 patients with diabetes and OSA and 3,842 patients with diabetes but no OSA. In the presence of comorbid OSA, patients with T2DM had higher odds of increased healthcare utilization among all the outcomes: inpatient visits increased with an odds ratio of 2.50 (confidence interval (CI) 2.28–2.74) and ICU admissions 1.96 (CI 1.73–2.25) ER 1.93 **(CI 1.75–2.12) and outpatient visits 2.18 (CI 2.00–2.38). Future healthcare utilization per 100 patient-years was also increased significantly among all outcomes (p < 0.0001).ConclusionsIn patients with diabetes undergoing elective surgery, the presence of OSA was associated with higher future healthcare utilization.

OBJECTIVETo examine the impact of urine culture testing on day 1 of admission on inpatient antibiotic use and hospital length of stay (LOS).DESIGNWe performed a retrospective cohort study using a national dataset from 2009 to 2014.SETTINGThe study used data from 230 hospitals in the United States.PARTICIPANTSAdmissions for adults 18 years and older were included in this study. Hospitalizations were matched with coarsened exact matching by facility, patient age, gender, Medicare severity-diagnosis related group (MS-DRG), and 3 measures of disease severity.METHODSA multilevel Poisson model and a multilevel linear regression model were used to determine the impact of an admission urine culture on inpatient antibiotic use and LOS.RESULTSMatching produced a cohort of 88,481 patients (n=41,070 with a culture on day 1, n=47,411 without a culture). A urine culture on admission led to an increase in days of inpatient antibiotic use (incidence rate ratio, 1.26; P<.001) and resulted in an additional 36,607 days of inpatient antibiotic treatment. Urine culture on admission resulted in a 2.1% increase in LOS (P=.004). The predicted difference in bed days of care between admissions with and without a urine culture resulted in 6,071 additional bed days of care. The impact of urine culture testing varied by admitting diagnosis.CONCLUSIONSPatients with a urine culture sent on day 1 of hospital admission receive more days of antibiotics and have a longer hospital stay than patients who do not have a urine culture. Targeted interventions may reduce the potential harms associated with low-yield urine cultures on day 1.Infect Control Hosp Epidemiol 2018;39:547-554.

Background. Overuse of urine testing is a driver of inappropriate antimicrobial use. Limiting wasteful testing is important for patient safety. We examined the national prevalence and patterns of urine testing during adult inpatient admission in the United States. Methods. We performed a retrospective cohort study using a national dataset of inpatient admissions from 263 hospitals in the United States from 2009 to 2014. We included all adult inpatient admissions, excluding those related to pregnancy, urology procedures, and with lengths of stay >30 days. A facility-level fixed-effects quasi-Poisson regression model was used to examine the incidence of urinalysis and urine culture testing for select diagnoses and patient factors. Results. The cohort included 4473655 admissions. Charges for urinalysis were present for 2086697 (47%) admissions, with 584438 (13%) including >1 urinalysis. Charges for urine culture were present for 1197242 (27%) admissions, with 246211 (6%) having >1 culture. Urine culture testing varied by principal diagnosis. Heart failure and acute myocardial infarction had 29% and 35% fewer cultures sent on the first day of admission compared to all other admissions (P < .001). Female sex and receipt of antibiotics during the hospital admission consistently predicted increased culture testing, regardless of principal diagnosis or age. Conclusions. Urine testing was common and frequently repeated during inpatient admission, suggesting large-scale overuse. The variation in testing by diagnosis suggests that clinical presentation modifies test use. The sex bias in urine testing is not clinically supported and must be addressed in interventions aimed at reducing excess urine testing.

The aim of this study was to validate a novel technique that predicts stopping of disease-modifying anti-rheumatic drugs (DMARDs) and biologic agents (BA) from the Veterans Affairs (VA) database and compare infection risks of rheumatoid arthritis patients who stopped versus continued DMARDs/BA perioperatively. We identified 6,024 patients on 1 DMARD or BA in the perioperative period between 1999 and 2009. Time gap between medication stop date and the next start date predicted drug stoppage (
X
). Time gap between surgery date and stop date predicted whether stoppage was before surgery (
Y
). Chart review from Houston VA was used for validation. ROC analyses were performed on chart review data to obtain
X
and
Y
cutoffs. The primary endpoints were wound infections and other infections within 30 days. ROC analyses found
X
≥ 33 (AUC = 0.954) and
Y
≥ −11 (AUC = 0.846). Risk of postoperative infections was not different when stopping and continuing DMARDs/BA preoperatively. Stopping BA after surgery was associated with higher odds of postoperative wound (OR 14.15, 95 % CI 1.76–113.76) and general infection (OR 9.2, 95 % CI 1.99–42.60) compared to not stopping. Stopping DMARDs after surgery was associated with increased risk of postoperative general infection (OR 1.84, 95 % CI 1.07–3.16) compared with not stopping. There was positive association between stopping DMARDs after surgery and postoperative wound infection but failed to achieve statistical significance (OR 1.67, 95 % CI 0.96–2.91). There was no significant difference in postoperative infection risk when stopping or continuing DMARD/BA. Our new validated method can be utilized in the VA and other databases to predict drug stoppage.

The use of sedation allows medical procedures to be performed outside the operating room while ensuring patient comfort and a controlled environment to increase the yield of the procedure. There is concern about a higher risk of adverse events with use of sedation in patients with obstructive sleep apnea.
We aimed to determine if the presence of obstructive sleep apnea increased the risk of hospitalization and/or health care use after patients received moderate conscious sedation for an elective, ambulatory colonoscopy.
We conducted a retrospective case-control database and chart review study. We compared hospital admissions, intensive care unit (ICU) admissions, and emergency room visits at 24 hours, 7 days, and 30 days in patients with obstructive sleep apnea (n = 3,860) and without obstructive sleep apnea (n = 2,374) who had undergone an elective, ambulatory colonoscopy with sedation.
We found no significant differences in hospital admissions, ICU admissions, or emergency room visits between the two groups at any time point within the 30 days following the procedures. In a sensitivity analysis in which we compared 827 individuals with polysomnographically confirmed sleep apnea with control subjects, there was still no difference in hospital admissions, ICU admissions, or emergency room visits in the 30 days after receiving sedation for the procedure. Outcomes were not different in individuals with various severities of obstructive sleep apnea.
The presence of obstructive sleep apnea was not associated with increased early hospital admissions, ICU admissions, or emergency room visits after colonoscopy with sedation.

To describe the visual outlook and quality of life of service members after combat ocular trauma.
In a single-center, prospective observational study of service members sustaining ocular trauma, participants underwent a series of ocular examinations and noninvasive tests, including the National Eye Institute Visual Functioning Questionnaire (VFQ-25).
Of the 165 enrolled participants, 137 completed the VFQ-25. The mean VFQ-25 composite score was 74.4 ± 20.7 (range: 1.4-100). Among 118 participants with visual acuity assessment, 92% had best corrected visual acuity (BCVA) of 20/20 or better in at least one eye. Among participants with severe vision loss (BCVA ≤20/200), there was no statistically significant difference in self-reported general health compared to those without severe vision loss (p = 0.17). However, there was a significantly lower visual quality of life reported in the composite score and all of the 11 subscales of the VFQ-25.
While this study provides evidence that combat ocular trauma is associated with a lower visual quality of life, limitations include the relatively small sample size and the limited documentation of the use of eye protection at time of injury among participants.
