A virtual multi-disciplinary meeting is a cost-effective method of triaging referrals to a regional musculoskeletal oncology service.

BACKGROUND AND AIMS: In 2010, a virtual sarcoma referral model was implemented, which aims to provide a centralised multidisciplinary team (MDT) to provide rapid advice, avoiding unnecessary appointments and providing a streamlined service. The aim of this study is to examine the feasibility of this screening tool in reducing the service burden and expediting patient journey. METHODS AND RESULTS: All referrals made to a single tertiary referral sarcoma unit from January 2010 to December 2018 were extracted from a prospective database. Only 26.0% events discussed required review directly. 30.3% were discharged back to referrer. 16.5% required further investigations. 22.5% required a biopsy prior to review. There was a reduction in the rate of patients reviewed at the sarcoma clinic, and a higher discharge rate from the MDT in 2018 versus 2010 (p < 0.001). This gives a potential cost saving of 670,700 GBP over the 9 year period. CONCLUSION: An MDT meeting which triages referrals is cost-effective at reducing unnecessary referrals. This can limit unnecessary exposure of patients who may have an underlying diagnosis of cancer to a high-risk environment, and reduces burden on services as it copes with increasing demands during the COVID-19 pandemic.

The Impact of FASTPASS: A Collaboration With Emergency Department to Improve Management of Patients With Gallbladder Disease and Acute Appendicitis.

BACKGROUND: Efficient Emergency Department (ED) throughput depends on several factors, including collaboration and consultation with surgical services. The acute care surgery service (ACS) collaborated with ED to implement a new process termed "FASTPASS" (FP), which might improve patient-care for those with acute appendicitis and gallbladder disease. The aim of this study was to evaluate the 1-year outcome of FP. METHODS: FASTPASS is a joint collaboration between ACS and ED. ED physicians were provided with a simple check-list for diagnosing young males (<50-year old) with acute appendicitis (AA) and young males or females (<50-year old) with gallbladder disease (GBD). Once ED deemed patients fit our FP check-list, patients were directly admitted (FASTPASSed) to the observation unit. The ACS then came to evaluate the patients for possible surgical intervention. We performed outcome analysis before and after the institution of the FP. Outcomes of interest were ED length of stay (LOS), time from ED to the operating room (OR) (door-to-knife), hospital LOS (HLOS), and cost. RESULTS: During our 1-year study period, for those patients who underwent GBD/AA surgery, 56 (26%) GBD and 27 (26%) AA patients met FP criteria. Compared to the non-FP patients during FP period, FP halved ED LOS for GBD (7.4 ± 3.0 versus 3.5 ± 1.7 h, P < 0.001) and AA (6.7 ± 3.3 versus. 1.8 ± 1.6 h, P < 0.001). Similar outcome benefits were observed for door-to-knife time, HLOS, and costs. CONCLUSIONS: In this study, the FP process improved ED throughput in a single, highly-trained ER leading to an overall improved patient care process. A future study involving multiple EDs and different disease processes may help decrease ED overcrowding and improve healthcare system efficiency.

Developing a tool that could reliably refute total thyroidectomy for solitary Bethesda IV thyroid nodules.

PURPOSE: To assess the reliability of a simple, accessible, cost-effective rule-out tool, for use in triaging patients with Bethesda IV nodules to appropriate surgery. METHODS: The diagnostic tool was assembled by combining the negativity for suspicious ultrasound features (irregular margins, microcalcification, and a taller-than-wide orientation), and mutational marker negativity (BRAF and NRAS). The tool, (US-/mutation-), was tested on 167 patients with solitary Bethesda IV nodules. The primary outcome was its negative predictive value (NPV) for lesions requiring total thyroidectomy (TT). The impact of mutational marker negativity, as part of the tool, was evaluated by comparing the NPV of (US-/mutation-) to that of (US-/mutation+). RESULTS: 10 out of 167 lesions were positive for a mutational marker. These underwent TT, and only 2/10 (20%) were benign, on final histology. In 6/8 malignant lesions, TT was concordant with current clinical guidelines. 157 patients comprised the negative study cohort, for both mutational markers and suspicious US features. These underwent thyroid lobectomy, and 17 cases resulted in malignancy, only 8 of which required completion thyroidectomy. Accordingly, the NPV of (US-/mutation-) for malignancy was 89% (140/157), and 95% (149/157) for malignancy requiring TT. However, the NPV of (US-/mutation+) was 20% for malignancy, and 40% for malignancy requiring TT. These differences were statistically significant (89% vs. 20%; p < 0.0001, and 95% vs. 40%; p < 0.0001). CONCLUSION: US-/mutation- is a reliable rule-out tool, with sufficient diagnostic accuracy to spare patients, with Bethesda IV nodules, an overly radical TT.

Comprehensive Community Screening of Otological Patients by Trained Technicians Using a Telemedicine Device: An Efficient and Cost-Effective Way to Triage Patients With Ear Diseases.

OBJECTIVE: To emphasize the benefits of tele-otology in community screening of patients with ear diseases. METHODS: A retrospective study of all patients screened and treated under the Shruti tele-otology program between 2013 and 2019 was conducted. It involved screening, diagnosis, medical management, surgical intervention, and rehabilitation using hearing aid. The study focused on underprivileged and underserved community of rural and urban slums across 12 states of India. The study was conducted using a telemedicine device called ENTraview, that is, a camera-enabled android phone integrated with an otoscope and audiometry screening. RESULT: A total of 810 746 people were screened, and incidence of various ear diseases was recorded. Ear problems were found in 265 615 (33%) patients, of which 151 067 (57%) had impacted wax, 46 792(18%) had chronic suppurative otitis media, 27 875 (10%) had diminished hearing, 12 729 (5%) had acute otitis media and acute suppurative otitis media (ASOM), and 27 152 (10%) had problems of foreign body, otomycosis, and so on. Of the total 265 615 referred patients, 20 986 (8%) reported for treatment and received treatment at a significantly reduced cost through Shruti program partners. The conversion rate of nonsurgical and surgical procedure was also compared, and it was found that, while 9% of the patients opted for nonsurgical treatment, only 3% opted for surgery in the intervention group giving a significant P value of .00001. CONCLUSION: The potential for telemedicine to reduce inequalities in health care is immense but remains underutilized. Shruti has largely been able to bridge this gap as it is an innovative, fast, and effective programs that address the ear ailment in the community.

Association of Practitioner Interfacility Triage Performance With Outcomes for Severely Injured Patients With Fee-for-Service Medicare Insurance.

Importance: Despite evidence that treatment of severely injured patients at trauma centers is associated with reduced mortality, nearly half of all such patients are treated at nontrauma centers (undertriaged). Little is known about whether interfacility undertriage occurs because of practitioner decision-making or institutional and regional factors. Objectives: To assess the associations between variation in triage practitioners at nontrauma centers and between practitioner-level variation and patient outcomes after injury. Design, Setting, and Participants: This retrospective cohort study used Medicare claims data from severely injured patients presenting to nontrauma centers and the practitioners who evaluated them in the emergency department from January 1, 2010, to October 15, 2015. Data analysis was performed from January 15, 2018, to March 21, 2019. Main Outcomes and Measures: Proportion of variation in undertriage associated with practitioners, practitioner rates of undertriage, practitioner characteristics associated with undertriage, and 30-day case-fatality rate. Results: A total of 124 008 severely injured patients (mean [SD] age, 81 [8.4] years; 67 253 [54.2%] female) and the 25 376 practitioners (5564 [21.9%] female) who evaluated the patients in the emergency department of nontrauma centers were included in the study. Undertriage occurred among 85 403 patients (68.9%), with 40.6% of total variation associated with practitioners, 37.8% with hospitals, and 6.7% with regions. Compared with physicians with National Provider Identification (NPI) enumeration before 2007, those with an NPI enumerated between 2007 and 2010 had an undertriage risk ratio (RR) of 0.98 (95% CI, 0.97-0.99), and those with an NPI enumerated after 2010 had an undertriage RR of 0.96 (95% CI, 0.94-0.99). Hospitals with neurosurgeons had an undertriage RR of 1.51 (95% CI, 1.45-1.57) compared with those that did not; hospitals with spine surgeons had an undertriage RR of 1.10 (95% CI, 1.06-1.13); hospitals with general surgeons had an undertriage RR of 1.13 (95% CI, 1.09-1.17). Compared with practitioners who undertriaged 25% or less of patients, a statistically significant increase was found in the odds of death for patients treated by practitioners with a triage rate of less than 25% to 50% (odds ratio [OR], 1.08; 95% CI, 1.05-1.20) and less than 50% to 75% undertriage (OR, 1.12; 95% CI, 1.09-1.26) but not undertriage at greater than 75% (OR, 1.03, 95% CI, 1.00-1.18). In sensitivity analyses to adjust for unmeasured confounding, the association between triage practices and the case fatality rate became monotonic; compared with patients treated by practitioners with an undertriage rate of 25% or less, the odds of case fatality were 1.13 (95% CI, 1.05-1.21; P = .001) among patients treated by practitioners with undertriage rates less than 25% to 50%, 1.22 (95% CI, 1.13-1.32; P < .001) for patients treated by practitioners with undertriage rates less than 50% to 75%, and 1.20 (95% CI, 1.10-1.30; P < .001) for patients treated by practitioners with undertriage rates greater than 75%. Conclusions and Relevance: The findings suggest that individual practitioner practices are an important source of variation in triage and represent a potential locus of intervention to reduce preventable deaths after injury.

Development of high-throughput ATR-FTIR technology for rapid triage of brain cancer.

Non-specific symptoms, as well as the lack of a cost-effective test to triage patients in primary care, has resulted in increased time-to-diagnosis and a poor prognosis for brain cancer patients. A rapid, cost-effective, triage test could significantly improve this patient pathway. A blood test using attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectroscopy for the detection of brain cancer, alongside machine learning technology, is advancing towards clinical translation. However, whilst the methodology is simple and does not require extensive sample preparation, the throughput of such an approach is limited. Here we describe the development of instrumentation for the analysis of serum that is able to differentiate cancer and control patients at a sensitivity and specificity of 93.2% and 92.8%. Furthermore, preliminary data from the first prospective clinical validation study of its kind are presented, demonstrating how this innovative technology can triage patients and allow rapid access to imaging.

Evaluating a risk assessment tool to improve triaging of patients to colonoscopies.

BACKGROUND: Colonoscopy is the gold standard in the diagnosis of significant bowel disease (SBD), including colorectal cancer, high-risk adenoma and inflammatory bowel disease. As the demand for colonoscopy services is placing significant pressure on hospital resources, new solutions are needed to manage patients more efficiently and effectively. AIM: We investigated the impact of using a risk assessment tool (RAT) to improve selection of patients for colonoscopy procedures to detect SBD. METHODS: A hybrid simulation model was constructed to replicate the current patient triage bookings and waiting times in a large metropolitan hospital. The model used data on 327 patients who were retrospectively assessed for risk of SBD. Risk assessment incorporated blood and faecal immunochemical test results, gender and age in addition to patient symptoms. The model was calibrated over 12 months to current outcomes and was compared with the RAT and a third scenario where low-risk patients did not proceed to a colonoscopy. One-way sensitivity analyses were undertaken. RESULTS: Using the RAT was expected to shorten waiting times by 153 days for moderately-urgent patients and 138 days for non-urgent patients. If low-risk patients did not proceed to colonoscopy, waiting times were expected to reduce for patients with SBD by 17 days producing cost-savings of AU$373 824 through avoided colonoscopies. CONCLUSIONS: A hybrid model that combines patient-level characteristics with hospital-level resource constraints can demonstrate improved efficiency in a hospital clinic. Further research on risk assessment is required to improve quality patient care and reduce low-value service delivery.

Modelling the impact of chest X-ray and alternative triage approaches prior to seeking a tuberculosis diagnosis.

BACKGROUND: Tuberculosis is a major challenge to health in the developing world. Triage prior to diagnostic testing could potentially reduce the volume of tests and costs associated with using the more accurate, but costly, Xpert MTB/RIF assay. An effective methodology to predict the impact of introducing triage prior to tuberculosis diagnostic testing could be useful in helping to guide policy. METHODS: The development and use of operational modelling to project the impact on case detection and health system costs of alternative triage approaches for tuberculosis, with or without X-ray, based on data from Porto Alegre City, Brazil. RESULTS: Most of the triage approaches modelled without X-ray were predicted to provide no significant benefit. One approach based on an artificial neural network applied to patient and symptom characteristics was projected to increase case detection (82% vs. 75%) compared to microscopy, and reduce costs compared to Xpert without triage. In addition, use of X-ray before diagnostic testing for HIV-negative patients could maintain diagnostic yield of using Xpert without triage, and reduce costs. CONCLUSION: A model for the impact assessment of alternative triage approaches has been tested. The results from using the approach demonstrate its usefulness in informing policy in a typical high burden setting for tuberculosis.

Reducing Cancer Costs Through Symptom Management and Triage Pathways.

PURPOSE: Value-based care infers care that is high quality at a comparatively low total cost. A key strategy for value-based oncology care is to avoid unnecessary emergency room (ER) visits and associated hospitalizations of patients receiving treatment for cancer. Early experience with this strategy showed that symptom management in patients with cancer can result in the reduction of ER events and hospitalizations. However, quantifying the actual savings achieved has been elusive. In this article, we present the impact of symptom management and triage pathways programs deployed at two midsize community oncology practices. We then quantify the actual dollar saving in their Medicare and commercial populations. METHODS: Symptom management records generated through the ER triage programs at the two practices were screened to identify avoided ER events. This approach was validated with an independent analysis using Medicare claim data from the Oncology Care Model program in which both practices participate. Bootstrap simulations were used to test for statistical significance of the ER event rate changes before and after the launch of the program. Average event and annual total cost savings from avoided ER incidents and ER-related hospitalizations were then calculated. RESULTS: Two hundred twenty-two avoided ER events were identified, for an estimated net annualized savings generated by the two practices of $3.85 million. Although the ER rate reduction was not statistically significant, these findings are consistent with the observed reduction of ER event rates among a subset of Oncology Care Model beneficiaries at the two practices. CONCLUSION: ER events and associated hospitalizations can be avoided as well as quantified as a result of the deployment of a practice-level integrated platform that incorporates physician-scripted symptom management protocols and telephone triage pathways.

Helistroke: neurointerventionalist helicopter transport for interventional stroke treatment: proof of concept and rationale.

BACKGROUND AND PURPOSE: It is increasingly recognized that time is one of the key determinants in acute stroke outcome when interventional stroke therapy is applied. With increasing device efficacy and understanding of imaging triage options, reducing pre-treatment time loss may be a critical component of improving interventional stroke outcomes for the population at large. Time sensitive procedures such as organ harvest have transported physicians to the patient site to improve time to procedure. Applying this same principle to interventional stroke management may be a valid paradigm. METHODS: Previous logistical deliberation with hospital and Medevac companies was carried out to provide the rationale and funding for helicopter transfer of a neurointerventionalist to an in-network hospital with an on-site angiographic suite. An appropriate patient with large vessel occlusion and an NIH Stroke Scale score >8 was identified. MRI was performed, then the Medevac transport system was activated and the intervention was carried out. Times were collected during the case and assessed for time efficiency. RESULTS: The proof of concept case was identified and Medevac was consulted at 12:13 after verifying that no in-house emergencies would prevent physician departure. Weather clearance was obtained and stroke intervention confirmed as a go at 12:24. Groin puncture occurred at 13:07 and the intervention was completed at 13:41. The total time from decision-to-treat to groin puncture was 43 min and groin closure was completed at 77 min from decision-to-treat. CONCLUSIONS: This proof of concept case is presented for logistical, financial and use-case analysis. As it is a first case, times can likely be improved. We assert that this model may be another option in the spoke-and-hub design of stroke systems of care.

High laboratory cost predicted per tuberculosis case diagnosed with increased case finding without a triage strategy.

SETTING: Cape Town, South Africa. OBJECTIVE: To model the effects of increased case finding and triage strategies on laboratory costs per tuberculosis (TB) case diagnosed. METHODS: We used a validated operational model and published laboratory cost data. We modelled the effect of varying the proportion with TB among presumptive cases and Xpert cartridge price reductions on cost per TB case and per additional TB case diagnosed in the Xpert-based vs. smear/culture-based algorithms. RESULTS: In our current scenario (18.3% with TB among presumptive cases), the proportion of cases diagnosed increased by 8.7% (16.7% vs. 15.0%), and the cost per case diagnosed increased by 142% (US$121 vs. US$50). The cost per additional case diagnosed was US$986. This would increase to US$1619 if the proportion with TB among presumptive cases was 10.6%. At 25.9-30.8% of TB prevalence among presumptive cases and a 50% reduction in Xpert cartridge price, the cost per TB case diagnosed would range from US$50 to US$59 (comparable to the US$48.77 found in routine practice with smear/culture). CONCLUSION: The operational model illustrates the effect of increased case finding on laboratory costs per TB case diagnosed. Unless triage strategies are identified, the approach will not be sustainable, even if Xpert cartridge prices are reduced.

Faecal immunochemical tests to triage patients with lower abdominal symptoms for suspected colorectal cancer referrals in primary care: a systematic review and cost-effectiveness analysis.

BACKGROUND: Colorectal cancer (CRC) is the third most common cancer in the UK. Presenting symptoms that can be associated with CRC usually have another explanation. Faecal immunochemical tests (FITs) detect blood that is not visible to the naked eye and may help to select patients who are likely to benefit from further investigation. OBJECTIVES: To assess the effectiveness of FITs [OC-Sensor (Eiken Chemical Co./MAST Diagnostics, Tokyo, Japan), HM-JACKarc (Kyowa Medex/Alpha Laboratories Ltd, Tokyo, Japan), FOB Gold (Sentinel/Sysmex, Sentinel Diagnostics, Milan, Italy), RIDASCREEN Hb or RIDASCREEN Hb/Hp complex (R-Biopharm, Darmstadt, Germany)] for primary care triage of people with low-risk symptoms. METHODS: Twenty-four resources were searched to March 2016. Review methods followed published guidelines. Summary estimates were calculated using a bivariate model or a random-effects logistic regression model. The cost-effectiveness analysis considered long-term costs and quality-adjusted life-years (QALYs) that were associated with different faecal occult blood tests and direct colonoscopy referral. Modelling comprised a diagnostic decision model, a Markov model for long-term costs and QALYs that were associated with CRC treatment and progression, and a Markov model for QALYs that were associated with no CRC. RESULTS: We included 10 studies. Using a single sample and 10 µg Hb/g faeces threshold, sensitivity estimates for OC-Sensor [92.1%, 95% confidence interval (CI) 86.9% to 95.3%] and HM-JACKarc (100%, 95% CI 71.5% to 100%) indicated that both may be useful to rule out CRC. Specificity estimates were 85.8% (95% CI 78.3% to 91.0%) and 76.6% (95% CI 72.6% to 80.3%). Triage using FITs could rule out CRC and avoid colonoscopy in approximately 75% of symptomatic patients. Data from our systematic review suggest that 22.5-93% of patients with a positive FIT and no CRC have other significant bowel pathologies. The results of the base-case analysis suggested minimal difference in QALYs between all of the strategies; no triage (referral straight to colonoscopy) is the most expensive. Faecal immunochemical testing was cost-effective (cheaper and more, or only slightly less, effective) compared with no triage. Faecal immunochemical testing was more effective and costly than guaiac faecal occult blood testing, but remained cost-effective at a threshold incremental cost-effectiveness ratio of £30,000. The results of scenario analyses did not differ substantively from the base-case. Results were better for faecal immunochemical testing when accuracy of the guaiac faecal occult blood test (gFOBT) was based on studies that were more representative of the correct population. LIMITATIONS: Only one included study evaluated faecal immunochemical testing in primary care; however, all of the other studies evaluated faecal immunochemical testing at the point of referral. Further, validation data for the Faecal haemoglobin, Age and Sex Test (FAST) score, which includes faecal immunochemical testing, showed no significant difference in performance between primary and secondary care. There were insufficient data to adequately assess FOB Gold, RIDASCREEN Hb or RIDASCREEN Hb/Hp complex. No study compared FIT assays, or FIT assays versus gFOBT; all of the data included in this assessment refer to the clinical effectiveness of individual FIT methods and not their comparative effectiveness. CONCLUSIONS: Faecal immunochemical testing is likely to be a clinically effective and cost-effective strategy for triaging people who are presenting, in primary care settings, with lower abdominal symptoms and who are at low risk for CRC. Further research is required to confirm the effectiveness of faecal immunochemical testing in primary care practice and to compare the performance of different FIT assays. STUDY REGISTRATION: This study is registered as PROSPERO CRD42016037723. FUNDING: The National Institute for Health Research Health Technology Assessment programme.

Using novel biomarkers to triage young adult women with minor cervical lesions: a cost-effectiveness analysis.

OBJECTIVE: To evaluate the short-term consequences and cost-effectiveness associated with the use of novel biomarkers to triage young adult women with minor cervical cytological lesions. DESIGN: Model-based economic evaluation using primary epidemiological data from Norway, supplemented with data from European and American clinical trials. SETTING: Organised cervical cancer screening in Norway. POPULATION: Women aged 25-33 years with minor cervical cytological lesions detected at their primary screening test. METHODS: We expanded an existing simulation model to compare 12 triage strategies involving alternative biomarkers (i.e. reflex human papillomavirus (HPV) DNA/mRNA testing, genotyping, and dual staining) with the current Norwegian triage guidelines. MAIN OUTCOME MEASURES: The number of high-grade precancers detected and resource use (e.g. monetary costs and colposcopy referrals) for a single screening round (3 years) for each triage strategy. Cost-efficiency, defined as the additional cost per additional precancer detected of each strategy compared with the next most costly strategy. RESULTS: Five strategies were identified as cost-efficient, and are projected to increase the precancer detection rate between 18 and 57%, compared with current guidelines; however, the strategies did not uniformly require additional resources. Strategies involving HPV mRNA testing required fewer resources, whereas HPV DNA-based strategies detected >50% more precancers, but were more costly and required twice as many colposcopy referrals compared with the current guidelines. CONCLUSION: Strategies involving biomarkers to triage younger women with minor cervical cytological lesions have the potential to detect additional precancers, yet the optimal strategy depends on the resources available as well as decision-makers' and women's acceptance of additional screening procedures. TWEETABLE ABSTRACT: Women with minor cervical lesions may be triaged more accurately and effectively using novel biomarkers.

The association of insurance status on the probability of transfer for pediatric trauma patients.

BACKGROUND/PURPOSE: The purpose of this study was to evaluate the association of insurance status on the probability of transfer of pediatric trauma patients to level I/II centers after initial evaluation at lower level centers. METHODS: A retrospective review of all pediatric trauma patients (age<16years) registered in the 2007-2012 National Trauma Data Bank was performed. Multiple regression techniques controlling for clustering at the hospital level were used to determine the impact of insurance status on the probability of transfer to level I/II trauma centers. RESULTS: Of 38,205 patients, 33% of patients (12,432) were transferred from lower level centers to level I/II trauma centers. Adjusting for demographics and injury characteristics, children with no insurance had a higher likelihood of transfer than children with private insurance. Children with public or unknown insurance status were no more likely to be transferred than privately insured children. There were no variable interactions with insurance status. CONCLUSIONS: Among pediatric trauma patients, lack of insurance is an independent predictor for transfer to a major trauma center. While burns, severely injured, and younger patients remain the most likely to be transferred, these findings suggest a triage bias influenced by insurance status. Additional policies may be needed to avoid unnecessary transfer of uninsured pediatric trauma patients. LEVEL OF EVIDENCE: Case-control study, level III.

Treatment strategies for stage IB cervical cancer: A cost-effectiveness analysis from Korean, Canadian and U.S. perspectives.

OBJECTIVES: To assess the cost-effectiveness of two commonly used strategies and an alternative triage strategy for patients with Stage IB cervical cancer in the U.S., Canada, and Korea. METHODS: A Markov state-transition model was constructed to compare three strategies: (1) radical hysterectomy followed by tailored adjuvant therapy (primary surgery), (2) primary chemoradiation, and (3) an MRI-based triage strategy, in which patients without risk factors in preoperative MRI undergo primary surgery and those with risk factors undergo primary chemoradiation. All relevant literature was identified to extract the probability data. Cost data were calculated from the perspective of U.S., Canadian, and Korean payers. Strategies were compared using an incremental cost-effectiveness ratio (ICER). Cost-effectiveness ratios were analyzed separately using data from each country. RESULTS: Base case analysis showed that the triage strategy was the most cost-effective of the three strategies in all countries at usual willingness-to-pay threshold (Korea: $30,000 per quality-adjusted life year (QALY), Canada and US: $100,000 per QALY). Monte Carlo simulation acceptability curves from Korea indicated that at a willingness-to-pay threshold of $30,000/QALY, triage strategy was the treatment of choice in 71% of simulations. Monte Carlo simulation acceptability curves from US and Canada indicated that at a willingness-to-pay threshold of $100,000/QALY, triage strategy was the treatment of choice in more than half of simulations. CONCLUSIONS: An MRI-based triage strategy was shown to be more cost-effective than primary surgery or primary chemoradiation in the US, Canada, and Korea.

Successful melanoma triage by a virtual lesion clinic (teledermatoscopy).

BACKGROUND: A Virtual Lesion Clinic (VLC) using teledermatoscopy was established to improve efficiency of the melanoma referral pathway. OBJECTIVES: To assess diagnostic accuracy and to compare wait-times and costs of VLC and conventional clinics. METHODS: Patients with suspected melanoma referred from primary care into a publicly funded health system attended local skin imaging centres, rather than hospital outpatient clinics. A teledermatologist assessed each lesion choosing specialist assessment/excision, General Practitioner (GP) follow-up, to re-image in 3 months, or self-monitoring/no concern. RESULTS: 613 skin lesions in 310 patients were evaluated over 12 months. Median time between receipt of referral and attendance at the VLC was 9 days compared to 26.5 days for standard outpatient assessment. Sixty-six percent (404/613) of lesions were considered benign, and 12% (73/613) were suspicious for melanoma. Of 129 lesions excised, 98 were skin cancers including 48 histologically confirmed melanomas with one spitzoid tumour of unknown malignant potential (STUMP), i.e. one melanoma per 1.59 suspected lesions biopsied and one melanoma in every 12.8 referred to the service. There were 49 non-melanoma skin cancers (NMSC). Teledermatoscopic diagnosis of melanomas was found to have a positive predictive value (PPV) of 63%. Compared to the conventional clinic, cost reductions from running the VLC for 1 year were in excess of NZ$364,000 (or NZ$1174/patient seen). CONCLUSIONS: The VLC offered an efficient, accurate and cost effective way of processing suspected melanoma referrals to the public health system.

Redesigned geriatric emergency care may have helped reduce admissions of older adults to intensive care units.

Charged with transforming geriatric emergency care by applying palliative care principles, a process improvement team at New York City's Mount Sinai Medical Center developed the GEDI WISE (Geriatric Emergency Department Innovations in Care through Workforce, Informatics, and Structural Enhancements) model. The model introduced workforce enhancements for emergency department (ED) and adjunct staff, including role redefinition, retraining, and education in palliative care principles. Existing ED triage nurses screened patients ages sixty-five and older to identify those at high risk of ED revisit and hospital readmission. Once fully trained, these nurses screened all but 6 percent of ED visitors meeting the screening criteria. Newly hired ED nurse practitioners identified high-risk patients suitable for and desiring palliative and hospice care, then expedited referrals. Between January 2011 and May 2013 the percentage of geriatric ED admissions to the intensive care unit fell significantly, from 2.3 percent to 0.9 percent, generating an estimated savings of more than $3 million to Medicare. The decline in these admissions cannot be confidently attributed to the GEDI WISE program because other geriatric care innovations were implemented during the study period. GEDI WISE programs are now running at Mount Sinai and two partner sites, and their potential to affect the quality and value of geriatric emergency care continues to be examined.

Lower cost strategies for triage of human papillomavirus DNA-positive women.

Using human papillomavirus (HPV) testing for cervical cancer screening in lower-resource settings (LRS) will result in a significant number of screen-positive women. This analysis compares different triage strategies for detecting cervical precancer and cancer among HPV-positive women in LRS. This was a population-based study of women aged 25-65 years living in China (n = 7,541). Each woman provided a self-collected and two clinician-collected specimens. The self-collected and one clinician-collected specimen were tested by two HPV DNA tests-careHPV™ and Hybrid Capture 2; the other clinician-collected specimen was tested for HPV16/18/45 E6 protein. CareHPV™-positive specimens were tested for HPV16/18/45 DNA. HPV DNA-positive women underwent visual inspection with acetic acid (VIA) and then colposcopic evaluation with biopsies. The performance for detection of cervical intraepithelial neoplasia grade 3 or cancer (CIN3+) among HPV DNA-positive women was assessed for different triage strategies: HPV16/18/45 E6 or DNA detection, VIA, colposcopic impression, or higher signal strength (≥10 relative light units/positive control [rlu/pc]). The percent triage positive ranges were 14.8-17.4% for VIA, 17.8-20.9% for an abnormal colposcopic impression; 7.9-10.5% for HPV16/18/45 E6; 23.4-28.4% for HPV16/18/45 DNA; and 48.0-62.6% for higher signal strength (≥10 rlu/pc), depending on the HPV test/specimen combination. The positivity for all triage tests increased with severity of diagnosis. HPV16/18/45 DNA detection was approximately 70% sensitive and had positive predictive values (PPV) of approximately 25% for CIN3+. HPV16/18/45 E6 detection was approximately 50% sensitive with a PPV of nearly 50% for CIN3+. Different triage strategies for HPV DNA-positive women provide important tradeoffs in colposcopy or treatment referral percentages and sensitivity for prevalent CIN3+.

Reducing inappropriate accident and emergency department attendances: a systematic review of primary care service interventions.

BACKGROUND: Inappropriate attendances may account for up to 40% of presentations at accident and emergency (A&E) departments. There is considerable interest from health practitioners and policymakers in interventions to reduce this burden. AIM: To review the evidence on primary care service interventions to reduce inappropriate A&E attendances. DESIGN AND SETTING: Systematic review of UK and international primary care interventions. METHOD: Studies published in English between 1 January 1986 and 23 August 2011 were identified from PubMed, the NHS Economic Evaluation Database, the Cochrane Collaboration, and Health Technology Assessment databases. The outcome measures were A&E attendances, patient satisfaction, clinical outcome, and intervention cost. Two authors reviewed titles and abstracts of retrieved results, with adjudication of disagreements conducted by the third. Studies were quality assessed using the Scottish Intercollegiate Guidelines Network checklist system where applicable. RESULTS: In total, 9916 manuscripts were identified, of which 34 were reviewed. Telephone triage was the single best-evaluated intervention. This resulted in negligible impact on A&E attendance, but exhibited acceptable patient satisfaction and clinical safety; cost effectiveness was uncertain. The limited available evidence suggests that emergency nurse practitioners in community settings and community health centres may reduce A&E attendance. For all other interventions considered in this review (walk-in centres, minor injuries units, and out-of-hours general practice), the effects on A&E attendance, patient outcomes, and cost were inconclusive. CONCLUSION: Studies showed a negligible effect on A&E attendance for all interventions; data on patient outcomes and cost-effectiveness are limited. There is an urgent need to examine all aspects of primary care service interventions that aim to reduce inappropriate A&E attendance.

Efficacy of anatomic and physiologic indicators versus mechanism of injury criteria for trauma activation in pediatric emergencies.

BACKGROUND: In pediatric trauma patients, adult triage criteria that use mechanism of injury (MOI) have been shown to result in overactivation of trauma teams. Anatomy- and physiology-based (APB) triage criteria have been recommended to improve the accuracy of trauma activations. At our Level 1 academic tertiary pediatric trauma referral center, we recently changed our triage criteria by emphasizing APB criteria and de-emphasizing MOI. This study was conducted to analyze the resulting change in accuracy of activations. METHODS: This was a criterion standard, cohort-controlled retrospective study comparing patients triaged by MOI criteria (January 2006 to March 2009) to those triaged by APB criteria (April 2009 to June 2010). Patients were subdivided according to trauma activation level as major (TMaj), minor (TMin), or consult (TC). Demographic, vital sign, injury pattern, trauma activation level, and emergency department disposition data were collected. Triage criteria were retrospectively applied to the patients according to the criteria that were in effect when they arrived. Patients were assigned to either high-risk (HR) or low-risk (LR) groups based on the need for urgent intervention (emergency department procedure, emergent operation, or blood transfusion), admission to intensive care unit, Injury Severity Score [ISS] of greater than 12, or death. Sensitivity and specificity of major activations were calculated using the following groups: true positive, trauma activation and HR; false positive, trauma activation and LR, false negative, no trauma activation and HR; true negative, no trauma activation and LR. Comparisons were then made between the MOI to the APB patients. RESULTS: The MOI and APB patients were similar in race (p = 0.201), sex (p = 0.639), and age (p = 0.643). The APB criteria resulted in 14% TMaj, 35% TMin, and 51% TC, compared with 41%, 23%, and 36%, respectively, for MOI. Median ISS in the APB group was 16 for TMaj, 5 for TMin, and 4 for TC compared with 8, 4, and 4, respectively, for MOI. Sensitivity for trauma activation of HR patients was 89.2% versus 89.1% (equivalent), while specificity increased from 45.8% to 65.8% for MOI versus APB, respectively. CONCLUSION: For pediatric trauma patients, the emphasis on APB triage criteria and de-emphasis on MOI results in selection of higher-acuity patients for major activation while maintaining acceptable undertriage and overtriage rates overall. This improved accuracy of major activation results in a more cost-efficient resource use and fewer unnecessary disruptions for the surgeon, operating room, and other staff while maintaining appropriate capture and evaluation of trauma patients. The low sensitivity noted in both the MOI and APB groups is largely caused by the broad definition of HR patients used in this study. We recommend the use of APB criteria for pediatric trauma triage. LEVEL OF EVIDENCE: Therapeutic study, level IV.
