Audit tool for external beam radiation therapy departments

PurposeDevelopment of a self-contained audit tool for external beam radiation therapy to assess compliance with the major recommendations from professional organizations and generally accepted standards of practice. Intensity modulated radiation therapy, stereotactic body radiation therapy, stereotactic radiosurgery, and volumetric modulated arc therapy were included in this review.Methods and MaterialsA physics quality working group developed a department vision, distinguished and summarized key references, and condensed important elements of good documentation practices. The results were then compiled in a checklist format and used to perform audits at 3 sites.ResultsThe final audit tool contains 65 items spanning a wide range of external beam radiation therapy practices. Several of the audit items address issues not commonly identified by other authoritative sources. A total of 48 process improvements were identified at the 3 sites audited.ConclusionsThe enclosed self-inspection list may be useful to a site as an annual review tool, as an aid in preparation for the American College of Radiology-American Society for Therapeutic Radiology and Oncology practice accreditation, or as a catalyst for general quality improvement. Sites can quickly identify opportunities for improvement by concentrating on high importance items and commonly identified areas of noncompliance.     

Study of mycotoxin calibration approaches on the example of trichothecenes analysis from flour

The aim of this study was to evaluate the applicability of different calibration approaches in trichothecenes analysis from wheat flour. Concretely eight trichothecenes (five type B trichothecenes and three type A trichothecenes) were analyzed by matrix solid-phase dispersion (MSPD) and liquid chromatography–tandem mass spectrometry (LC–MS/MS). In the first set of experiments the presence of matrix effects was evaluated; values ranged between 59% and 79%. In the second set of experiments, solutions to compensate these signal suppressions were examined. Different calibration methods showed to tackle matrix effects obtaining values between 69% and 85% for external matrix matched calibration and values from 76% to 111% and from 78% to 108% by analog and deuterated internal standard calibrations, respectively. Trueness of the method was studied using quality control material and certificated reference material (DON 1062 ± 110 μg kg⁻¹). The values were compared by matrix-matched, analog internal standard (deepoxydeoxynivalenol (DOM-1)) and deuterated internal standard (DON-d₁).     

The Architecture of a Software System for Supporting Community-based Primary Health Care with Mobile Technology: The Mobile Technology for Community Health (MoTeCH) Initiative in Ghana

This paper describes the software architecture of a system designed in response to the health development potential of two concomitant trends in poor countries: i) The rapid expansion of community health worker deployment, now estimated to involve over a million workers in Africa and Asia, and ii) the global proliferation of mobile technology coverage and use. Known as the Mobile Technology for Community Health (MoTeCH) Initiative, our system adapts and integrates existing software applications for mobile data collection, electronic medical records, and interactive voice response to bridge health information gaps in rural Africa. MoTeCH calculates the upcoming schedule of care for each client and, when care is due, notifies the client and community health workers responsible for that client. MoTeCH also automates the aggregation of health status and health service delivery information for routine reports. The paper concludes with a summary of lessons learned and future system development needs.     

Peri-operative outcomes of patients with stage IV endometriosis undergoing robotic-assisted laparoscopic surgery

We analyzed peri-operative outcomes of 80 patients who underwent robotic-assisted laparoscopic surgery and were diagnosed with stage IV endometriosis (revised American Society for Reproductive Medicine) between January 2007 and December 2010 at a tertiary gynecologic oncology referral center with a fellowship training program. Eligible women had a combination of one or more factors: pelvic mass, sub-acute or chronic pelvic pain, dysmenorrhea, dyspareunia, elevated serum CA-125, diagnosed with stage IV endometriosis at surgery with robotic-assisted gynecologic procedures using the da Vinci^? Surgical System. The mean age was 43.7?±?7.0?years, body mass index 27.5?±?7.4?kg/m², and 23 (28.9%) patients had prior endometriosis surgery. Presenting symptoms included: chronic pelvic pain (48.8%), dysmenorrhea (40.3%), and dyspareunia (33.8%). Sixty-nine (86%) patients had pelvic masses (43 unilateral and 26 bilateral). Thirty-seven (46.3%) had elevated CA-125 levels (mean 97.9?±?71.6 U/ml). Forty-eight (60%) underwent robotic-assisted laparoscopic hysterectomy (RALH)/bilateral salpingo-oophorectomy (BSO), 9 (11.3%) RALH/unilateral salpingo-oophorectomy (USO), 5 (6.3%) modified radical hysterectomy, and 10 (13%) USO or BSO only. Four (5%) had ovarian cystectomies with excision of endometriotic implants. Three (3.8%) underwent appendectomy and no patient required bowel resection. Four (5%) patients required conversion to laparotomy during the first 15 cases of this series [dense adhesions (3) and ureteral injury (1)]. Mean operative time was 115?±?46?min, blood loss 88?±?67?ml, and length of stay 1.0?±?0.4?days. There were four (5%) complications (ureteral injury, cuff abscess, cuff hematoma, re-admission for nausea and vomiting secondary to narcotics) and no transfusions. One (1.3%) patient underwent a second surgery for pain (dyspareunia). Robotic-assisted surgery for stage IV endometriosis resulted in excellent pain relief, with few laparotomy conversions or complications during a robotic learning-curve experience.
