Background Prompt, complete, and accurate information transfer at the time of discharge between hospital-based and primary care providers (PCPs) is needed for the provision of safe and effective care. Purpose of the Study To evaluate timeliness, quality, and interventions to improve timeliness and quality of hospital discharge summaries. Data Sources PubMed, MEDLINE, EMBASE, CINAHL, Web of Science, and Scopus database published in English between January 2007 and February 2014 were searched. We also hand-searched bibliographies of relevant articles. Study Selection Observational studies investigating transfer of information at hospital discharge (n = 7) and controlled studies evaluating interventions to improve timeliness and quality of discharge information (n = 12) were included. Data Extraction We extracted data on availability, timeliness, and content of hospital discharge summaries and on the effectiveness of interventions targeting discharge summaries. Results of studies are presented narratively and using descriptive statistics. Data Synthesis Across the studies, discharge summaries were completed within 48 hours in a median of 67% and were available to PCPs within 48 hours only 55% of the time. Most of the time, discharge summaries included demographics, primary diagnosis, hospital course, and discharge instructions. However, information was limited to pending test results (25%), diagnostic tests performed (60%), and postdischarge medications (78%). In 6 interventional studies, implementation of electronic discharge summaries was associated with improvement in timeliness but not quality. Conclusions Delayed or insufficient transfer of discharge information between hospital-based providers and PCPs remains common. Creation of electronic discharge summaries seems to improve timeliness and availability but does not consistently improve quality.

SummaryBackgroundThyroid ultrasound to assess for nodular growth is commonly performed during the follow‐up of patients with benign thyroid nodules, with the goal of identifying patients with a missed diagnosis of thyroid cancer. The objective of this study was to summarize the evidence regarding the diagnostic accuracy of growth during follow‐up of benign thyroid nodules for thyroid cancer.MethodsWe searched multiple electronic databases using a search strategy designed by an experienced medical librarian from inception to March 2015. Eligible studies included patients with benign thyroid nodules assessed for growth during follow‐up and evaluated for thyroid cancer either by surgical histology or a repeat fine needle aspiration biopsy. Reviewers working independently and in duplicate recorded data and assessed each study.ResultsThe seven eligible studies lacked safeguards against bias and generated results that were imprecise with wide confidence intervals and inconsistent across studies. This warrants very low confidence in these results. The odds of nodule growth in patients with thyroid cancer on histopathology over these odds in patients without thyroid cancer (diagnostic odds ratio) was 0·58 (95% CI: 0·26–1·3); the diagnostic odds ratio was 2·2 (95% CI: 0·26–18) when an abnormal repeat biopsy was the reference standard.ConclusionThe body of evidence linking nodule growth with thyroid cancer during the follow‐up of benign nodules warrants very low confidence. In the era of high‐value health care, the commonplace practice of following benign thyroid nodules with serial ultrasound assessment of growth to diagnose cancer can be questioned, calling for imminent evaluation.

AbstractBackgroundAsthma guidelines suggest reducing controller medications when asthma is stable.MethodsThe purpose of the study is to estimate the risk of asthma exacerbation in stable asthmatics who reduce inhaled corticosteroids (ICS) compared to those who maintain a stable ICS dose. We identified articles from a systematic review of English and non‐English articles using MEDLINE, EMBASE, Web of Science, and CENTRAL (inception to May 25, 2013). We included randomized controlled trials (RCTs) with a stable asthma run‐in period of 4 weeks or more, an intervention to reduce ICS, and a follow‐up period of at least 3 months.ResultsThe search strategy identified 2253 potential articles, of which 206 were reviewed at the full‐text level and 6 met criteria for inclusion. The relative risk of an asthma exacerbation in individuals who reduced ICS compared to those who maintained the same ICS dose was 1.25 (95% CI 0.96, 1.62; P = 0.10; I2 = 0%) in studies with a mean follow‐up of 22 weeks. Individuals who reduced ICS had a decreased% predicted FEV1 of 0.87% (95% CI −1.58%,3.33%; P = 0.49, I2 = 58%) and a decreased mean morning peak expiratory flow of 9.57 l/min (95% CI 1.25, 17.90; P = 0.02; I2 = 74%) compared to those individuals who maintained a stable ICS dose.ConclusionsAsthma exacerbations were statistically no more likely among individuals who reduced ICS compared to those who maintained their ICS dose, supporting current guidelines which recommend decreasing ICS by 50% after a period of asthma stability.

Purpose Open fractures are considered orthopedic emergencies that are traditionally treated with surgical debridement within 6 h of injury to prevent infection. However, this proclaimed “6-h rule” is arbitrary and not based on rigorous scientific evidence. The aim of our study was to systematically review the literature that compares late (>6 h from the time of injury) to early (<6 h from the time of injury) surgical debridement of pediatric open fractures. Methods We searched several databases from 1946 to 2013 for any observational or experimental studies that evaluated late and early surgical debridement of pediatric open fractures. We performed a meta-analysis using a random effects model to pool odds ratios for a comparison of infection rates between children undergoing late versus early surgical debridement. We also investigated the infection rates in upper- and lower-limb pediatric open fractures. Descriptive, quantitative, and qualitative data were extracted. Results Of the 12 articles identified, three studies (retrospective cohort studies) were eligible for the meta-analysis, encompassing a total of 714 open fractures. The pooled odds ratio (OR = 0.79) for infection between late and early surgical debridement was in favor of late surgical debridement but was not statistically significant (95 % CI 0.32, 1.99; p = 0.38, I 2 = 0 %). No significant difference in infection rate was detected between pediatric open fractures in the upper and lower limbs according to the time threshold in the included studies (OR = 0.72, 95 % CI 0.29, 1.82; p = 0.40, I 2 = 0 %). Conclusions The cumulative evidence does not, at present, indicate an association between late surgical debridement and higher infection rates in pediatric open fractures. However, initial expedient surgical debridement of open fractures in children should always remain the rule. Thus, multi-center randomized controlled trials or prospective cohort studies will be able to answer this question with more certainty and a higher level of evidence. Level of evidence Level III.

Objective: We conducted a systematic review and meta-analysis to assess the efficacy of continuous glucose monitoring (CGM) in improving glycemic control and reducing hypoglycemia compared to self-monitored blood glucose (SMBG). Methods: We searched MEDLINE, EMBASE, Cochrane Central, Web of Science, and Scopus for randomized trials of adults and children with type 1 or type 2 diabetes mellitus (T1DM or T2DM). Pairs of reviewers independently selected studies, assessed methodological quality, and extracted data. Meta-analytic estimates of treatment effects were generated using a random-effects model. Results: Nineteen trials were eligible and provided data for meta-analysis. Overall, CGM was associated with a significant reduction in mean hemoglobin A1c [HbA1c; weighted mean difference (WMD) of −0.27% (95% confidence interval [CI] −0.44 to −0.10)]. This was true for adults with T1DM as well as T2DM [WMD −0.50% (95% CI −0.69 to −0.30) and −0.70 (95% CI, −1.14 to −0.27), respectively]. No significant effect was noted in children and adolescents. There was no significant difference in HbA1c reduction between studies of real-time versus non-real-time devices (WMD −0.22%, 95% CI, −0.59 to 0.15 versus −0.30%, 95% CI, −0.49 to −0.10; p for interaction 0.71). The quality of evidence was moderate due to imprecision, suggesting increased risk for bias. Data for the incidence of severe or nocturnal hypoglycemia were sparse and imprecise. In studies that reported patient satisfaction, users felt confident about the device and gave positive reviews. Conclusion: Continuous glucose monitoring seems to help improve glycemic control in adults with T1DM and T2DM. The effect on hypoglycemia incidence is imprecise and unclear. Larger trials with longer follow-up are needed to assess the efficacy of CGM in reducing patient-important complications without significantly increasing the burden of care for patients with diabetes.
