We recommend that endoscopy in children be performed by pediatric-trained endoscopists whenever possible. We recommend that adult-trained endoscopists coordinate their services with pediatricians and pediatric specialists when they are needed to perform endoscopic procedures in children. We recommend that endoscopy be performed within 24 hours in symptomatic pediatric patients with known or suspected ingestion of caustic substances. We recommend emergent foreign-body removal of esophageal button batteries, as well as 2 or more rare-earth neodymium magnets. We recommend that procedural and resuscitative equipment appropriate for pediatric use should be readily available during endoscopic procedures. We recommend that personnel trained specifically in pediatric life support and airway management be readily available during sedated procedures in children. We recommend the use of endoscopes smaller than 6 mm in diameter in infants and children weighing less than 10 kg. We recommend the use of standard adult duodenoscopes for performing ERCP in children who weigh at least 10 kg. We recommend the placement of 12F or 16F percutaneous endoscopic gastrostomy tubes in children who weigh less than 50 kg.

We conducted a longitudinal study of a community-based cohort of HIV-infected indigent adults to examine smoking behaviors and factors associated with quitting. We assessed "hardcore" smoking behaviors associated with a low probability of quitting. Of the 296 participants, 218 were current smokers (73.6 %). The prevalence of "hardcore" smoking was high: 59.6 % smoked ≥15 cigarettes per day, and 67.3 % were daily smokers. During the study interval, 20.6 % made at least one quit attempt. Of these, 53.3 % were abstinent at 6 months. The successful quit rate over 2 years was 4.6 %. Illegal substance use (adjusted odds ratio, AOR 0.2, 95 % CI 0.1-0.6) and smoking within 30 min of waking (AOR 0.2, 95 % CI 0.1-0.7) were associated with lower likelihood of making a quit attempt. Interventions that reduce nicotine dependence prior to smoking cessation and those that are integrated with substance use treatment may be effective for this population.

BACKGROUND

Online patient portals are being widely implemented, but their impact on health behaviors are not well-studied.

OBJECTIVE

To determine whether statin adherence improved after initiating use of the portal refill function.

RESEARCH DESIGN

Observational cohort study within an integrated health care delivery system.

SUBJECTS

Diabetic patients on statins who had registered for online portal access by 2010. A total of 8705 subjects initiated the online refill function use within the study window, including "exclusive" and "occasional" users (ie, requesting all vs. some refills online, respectively). Using risk-set sampling, we temporally matched 9055 reference group patients who never used online refills.

MEASURES

We calculated statin adherence before and after refill function initiation, assessed as percent time without medications (nonadherence defined as a gap of >20%). Secondary outcome was dyslipidemia [low-density lipoprotein (LDL)≥ 100]. Difference-in-differences regression models estimated pre-post changes in nonadherence and dyslipidemia, comparing refill function users to the reference group and adjusting for age, sex, race/ethnicity, medications, frequency of portal use, and outpatient visits.

RESULTS

In unadjusted examinations, nonadherence decreased only among patients initiating occasional or exclusive use of the refill function (26%-24% and 22%-15%, respectively). In adjusted models, nonadherence declined by an absolute 6% (95% confidence interval, 4%-7%) among exclusive users, without significant changes among occasional users. Similar LDL decreases were also seen among exclusive users.

CONCLUSIONS

Compared with portal users who did not refill medications online, adherence to statin medications and LDL levels improved among diabetic patients who initiated and exclusively used the patient portal for refills, suggesting that wider adoption of online refills may improve adherence.
