Discharge prescribing and subsequent opioid use after traumatic musculoskeletal injury.

OBJECTIVE: To investigate the effects of discharge opioid supply after surgery for musculoskeletal injury on subsequent opioid use. STUDY DESIGN: Instrumental variables analysis of retrospective administrative data. METHODS: Data were acquired on 1039 patients treated operatively for a musculoskeletal injury between 2011 and 2015 at 2 level I trauma centers. State registry data were used to track all postoperative opioid prescription fills. Discharge surgical resident was identified for each patient. We categorized residents in the top one-third of opioid prescribing as high-supply residents and others as low-supply residents, with adjustment for service attending physician and month. The primary outcome was subsequent opioid use, defined as new opioid prescriptions and cumulative prescribed opioid supply 7 to 8 months after injury. RESULTS: On average, patients of high-supply residents received an additional 96 morphine milligram equivalents (MME) at discharge (95% CI, 29-163 MME; P < .01), or 16% more, compared with patients of low-supply residents, which is equivalent to an additional 2-day supply at a typical dosage. In the seventh or eighth month after surgery, patients of high-supply residents received a greater total MME volume than patients of low-supply residents (difference, 13.0 MME; 95% CI, 3.1-22.9 MME; P < .01) despite receiving a greater cumulative supply of opioid medications through the sixth month after surgery. CONCLUSIONS: After surgery for musculoskeletal injury, patients discharged by residents who prescribe greater supplies of opioid pain medications received higher supplies of opioids 7 to 8 months after surgery than patients discharged by residents who tend to prescribe less. Thus, limiting postoperative supplies of opioid pain medication may help reduce chronic opioid use.

Novel hybrid biocomposites for tendon grafts: The addition of silk to polydioxanone and poly(lactide-co-caprolactone) enhances material properties, in vitro and in vivo biocompatibility.

Biopolymers play a critical role as scaffolds used in tendon and ligament (TL) regeneration. Although advanced biopolymer materials have been proposed with optimised mechanical properties, biocompatibility, degradation, and processability, it is still challenging to find the right balance between these properties. Here, we aim to develop novel hybrid biocomposites based on poly(p-dioxanone) (PDO), poly(lactide-co-caprolactone) (LCL) and silk to produce high-performance grafts suitable for TL tissue repair. Biocomposites containing 1-15% of silk were studied through a range of characterisation techniques. We then explored biocompatibility through in vitro and in vivo studies using a mouse model. We found that adding up to 5% silk increases the tensile properties, degradation rate and miscibility between PDO and LCL phases without agglomeration of silk inside the composites. Furthermore, addition of silk increases surface roughness and hydrophilicity. In vitro experiments show that the silk improved attachment of tendon-derived stem cells and proliferation over 72 h, while in vivo studies indicate that the silk can reduce the expression of pro-inflammatory cytokines after six weeks of implantation. Finally, we selected a promising biocomposite and created a prototype TL graft based on extruded fibres. We found that the tensile properties of both individual fibres and braided grafts could be suitable for anterior cruciate ligament (ACL) repair applications.

Diagnosing malignant melanoma in ambulatory care: a systematic review of clinical prediction rules.

OBJECTIVES: Malignant melanoma has high morbidity and mortality rates. Early diagnosis improves prognosis. Clinical prediction rules (CPRs) can be used to stratify patients with symptoms of suspected malignant melanoma to improve early diagnosis. We conducted a systematic review of CPRs for melanoma diagnosis in ambulatory care. DESIGN: Systematic review. DATA SOURCES: A comprehensive search of PubMed, EMBASE, PROSPERO, CINAHL, the Cochrane Library and SCOPUS was conducted in May 2015, using combinations of keywords and medical subject headings (MeSH) terms. STUDY SELECTION AND DATA EXTRACTION: Studies deriving and validating, validating or assessing the impact of a CPR for predicting melanoma diagnosis in ambulatory care were included. Data extraction and methodological quality assessment were guided by the CHARMS checklist. RESULTS: From 16 334 studies reviewed, 51 were included, validating the performance of 24 unique CPRs. Three impact analysis studies were identified. Five studies were set in primary care. The most commonly evaluated CPRs were the ABCD, more than one or uneven distribution of Colour, or a large (greater than 6 mm) Diameter (ABCD) dermoscopy rule (at a cut-point of >4.75; 8 studies; pooled sensitivity 0.85, 95% CI 0.73 to 0.93, specificity 0.72, 95% CI 0.65 to 0.78) and the 7-point dermoscopy checklist (at a cut-point of ≥1 recommending ruling in melanoma; 11 studies; pooled sensitivity 0.77, 95% CI 0.61 to 0.88, specificity 0.80, 95% CI 0.59 to 0.92). The methodological quality of studies varied. CONCLUSIONS: At their recommended cut-points, the ABCD dermoscopy rule is more useful for ruling out melanoma than the 7-point dermoscopy checklist. A focus on impact analysis will help translate melanoma risk prediction rules into useful tools for clinical practice.

Hospital-based, Multidisciplinary, youth mentoring and medical exposure program positively influences and reinforces health care career choice: "The Reach One Each One Program early Experience".

BACKGROUND: According to the National Center for Educational Statistics, underrepresented minorities (URMs) are more likely to leave science, technology, engineering and mathematics (STEM) fields at higher rates than their peers during undergraduate studies. Many institutions of higher learning have implemented pipeline programs aimed at preparing and inspiring high school and college aged students in select careers in health sciences with varying levels of success. Research has shown that a health care workforce that mirrors the community they serve is more effective in reducing health disparities and increasing positive health outcomes. We hypothesize that a hospital-based, multidisciplinary youth mentoring and medical exposure program will enhance the decision of URM high school students to choose healthcare careers. MATERIALS AND METHOD: A retrospective analysis of the Reach One Each One Program (ROEO) was performed. ROEO is a hospital based, 11-week multidisciplinary youth mentoring and medical exposure program for inner-city high school students. The analysis was based on a phone survey of the twenty-six (26) seniors who completed the program and subsequently graduated from high school between May 2013 and May 2015 to assess the following: 1) College enrollment/attendance, 2) Health profession majors, and 3) Pre-med status. The study was approved by the Morehouse School of Medicine Institutional Review Board. RESULTS: Of the twenty-six students, 23 were female and 3 were male; 25 (96%) of the students were African American and one student was a Caucasian female. Twenty-four (92.3%) of the students were enrolled in college and 2 (7.7%) were scheduled to begin in the spring semester of 2016. Twenty-one of the 24 attending college at the time of the survey (87.5%) were enrolled in a health science degree program and 16 (66.7%) confirmed that they were enrolled in pre-medical (Pre-med) curriculum. CONCLUSION: Hospital-based, multidisciplinary medical mentoring programs can have a positive impact on the lives and health care career decisions of aspiring URM high school students. Further study will be necessary to validate the most influential components needed for the success of such programs.
