Normal Risk Ovarian Screening Study: 21-Year Update.

PURPOSE: The Normal Risk Ovarian Screening Study (NROSS) tested a two-stage screening strategy in postmenopausal women at conventional hereditary risk where significantly rising cancer antigen (CA)-125 prompted transvaginal sonography (TVS) and abnormal TVS prompted surgery to detect ovarian cancer. METHODS: A total of 7,856 healthy postmenopausal women were screened annually for a total of 50,596 woman-years in a single-arm study (ClinicalTrials.gov identifier: NCT00539162). Serum CA125 was analyzed with the Risk of Ovarian Cancer Algorithm (ROCA) each year. If risk was unchanged and <1:2,000, women returned in a year. If risk increased above 1:500, TVS was undertaken immediately, and if risk was intermediate, CA125 was repeated in 3 months with a further increase in risk above 1:500 prompting referral for TVS. An average of 2% of participants were referred to TVS annually. RESULTS: Thirty-four patients were referred for operations detecting 15 ovarian cancers and two borderline tumors with 12 in early stage (I-II). In addition, seven endometrial cancers were detected with six in stage I. As four ovarian cancers and two borderline tumors were diagnosed with a normal ROCA, the sensitivity for detecting ovarian and borderline cancer was 74% (17 of 23), and 70% of ROCA-detected cases (12 of 17) were in stage I-II. NROSS screening reduced late-stage (III-IV) disease by 34% compared with UKCTOCS controls and by 30% compared with US SEER values. The positive predictive value (PPV) was 50% (17 of 34) for detecting ovarian cancer and 74% (25 of 34) for any cancer, far exceeding the minimum acceptable study end point of 10% PPV. CONCLUSION: While the NROSS trial was not powered to detect reduced mortality, the high specificity, PPV, and marked stage shift support further development of this strategy.

Autoantibodies, antigen-autoantibody complexes and antigens complement CA125 for early detection of ovarian cancer.

BACKGROUND: Multiple antigens, autoantibodies (AAb), and antigen-autoantibody (Ag-AAb) complexes were compared for their ability to complement CA125 for early detection of ovarian cancer. METHODS: Twenty six biomarkers were measured in a single panel of sera from women with early stage (I-II) ovarian cancers (n = 64), late stage (III-IV) ovarian cancers (186), benign pelvic masses (200) and from healthy controls (502), and then split randomly (50:50) into a training set to identify the most promising classifier and a validation set to compare its performance to CA125 alone. RESULTS: Eight biomarkers detected ≥ 8% of early stage cases at 98% specificity. A four-biomarker panel including CA125, HE4, HE4 Ag-AAb and osteopontin detected 75% of early stage cancers in the validation set from among healthy controls compared to 62% with CA125 alone (p = 0.003) at 98% specificity. The same panel increased sensitivity for distinguishing early-stage ovarian cancers from benign pelvic masses by 25% (p = 0.0004) at 95% specificity. From 21 autoantibody candidates, 3 AAb (anti-p53, anti-CTAG1 and annt-Il-8) detected 22% of early stage ovarian cancers, potentially lengthening lead time prior to diagnosis. CONCLUSION: A four biomarker panel achieved greater sensitivity at the same specificity for early detection of ovarian cancer than CA125 alone.

A Multicenter Allelic Analysis of Diffuse Idiopathic Skeletal Hyperostosis: Nature Versus Nurture?

BACKGROUND: Diffuse idiopathic skeletal hyperostosis (DISH) is an incompletely defined disease process with no known unifying pathophysiological mechanism. OBJECTIVE: To our knowledge, no genetic studies have been performed in a North American population. To summarize genetic findings from previous studies and to comprehensively test for these associations in a novel and diverse, multi-institutional population. METHODS: Cross-sectional, single nucleotide polymorphism (SNP) analysis was performed in 55 of 121 enrolled patients with DISH. Baseline demographic data were available on 100 patients. Based on allele selection from previous studies and related disease conditions, sequencing was performed on COL11A2, COL6A6, fibroblast growth factor 2 gene, LEMD3, TGFB1, and TLR1 genes and compared with global haplotype rates. RESULTS: Consistent with previous studies, older age (mean 71 years), male sex predominance (80%), a high frequency of type 2 diabetes (54%), and renal disease (17%) were observed. Unique findings included high rates of tobacco use (11% currently smoking, 55% former smoker), a higher predominance of cervical DISH (70%) relative to other locations (30%), and an especially high rate of type 2 diabetes in patients with DISH and ossification of the posterior longitudinal ligament (100%) relative to DISH alone (100% vs 47%, P < .001). Compared with global allele rates, we found higher rates of SNPs in 5 of 9 tested genes ( P < .05). CONCLUSION: We identified 5 SNPs in patients with DISH that occurred more frequently than a global reference. We also identified novel environmental associations. We hypothesize that DISH represents a heterogeneous condition with both multiple genetic and environmental influences.

Disparities from bedside to "webside": barriers to achieving equity in telemedicine in obstetrics.

Given the urgency of the COVID-19 pandemic, telehealth was swiftly implemented in the United States and shifted from an optional to an essential modality of care. This was important in both maintaining continuity of care, especially for those with chronic illnesses, and in evaluating individuals presenting with illness or acute needs. One of the primary benefits of telemedicine is convenience; however, this is juxtaposed with the various downsides that result from a lack of physical appointments and accessible technology. Notably, there are large barriers to achieving equity for certain communities, of which the most apparent is the "digital divide" that results from a lack of adequate broadband infrastructure and lower technology literacy among members of certain communities and those in rural areas. Without attention to factors that can improve availability, uptake, and experience, disparities will increase with telemedicine. As this technology becomes common practice, it will be important to provide equal reimbursement for in-person and telehealth visits, center patient design and cultural competency in telemedicine programs, and improve broadband and technology access, ensuring that the highest-quality care is delivered to all patients.

The disproportionately large contribution of the Maori and Pacific Islander community to the healthcare burden of gout in Western Sydney.

BACKGROUND: Gout is a common chronic inflammatory disorder due to monosodium urate deposition, which results in severe inflammatory arthritis. It is particularly common in those of Maori or Pacific Islander heritage. There is a significant number of this at-risk ethnic group in western Sydney. AIMS: To determine the healthcare burden of gout in Western Sydney. METHODS: We characterised patients managed in the emergency departments (EDs) of the four Western Sydney Local Health District (WSLHD) hospitals and those admitted for gout as the primary or secondary diagnosis from 1 January 2017 to 31 December 2018. RESULTS: There were 472 patients managed in ED on 552 occasions at a direct cost to the LHD of A$367 835. Those of Maori or Pacific Islander ethnicity comprised 25.2% (n = 119/472), while half (n = 39/80) of those managed in ED for gout on two or more occasions were of Maori or Pacific Islander ethnicity. Overall, 310 patients were admitted with gout as the principal diagnosis on 413 occasions at a cost of A$1.73 million. Seventy-five (24.2%) of the 310 patients were of Maori or Pacific Islander heritage. A total of 584 WSLHD inpatients had gout as a secondary diagnosis. This was associated with 714 admissions. CONCLUSIONS: The disproportionately large healthcare burden of gout in Western Sydney from the relatively small Maori and Pacific Islander population needs attention. Urgent culturally appropriate interventions to address gout are required to address this inequality.

Chasing the Cup: A Comprehensive Review of Spinal Cord Injuries in Hockey.

Ice hockey is a high-speed sport with a high rate of associated injury, including spinal cord injury (SCI). The incidence of hockey-related SCI has increased significantly in more recent years. A comprehensive literature search was conducted with the PubMed, Medline, Google Scholar, and Web of Science databases using the phrases "hockey AND spinal cord injuries" to identify relevant studies pertaining to hockey-related SCIs, equipment use, anatomy, and biomechanics of SCI, injury recognition, and return-to-play guidelines. Fifty-three abstracts and full texts were reviewed and included, ranging from 1983 to 2021. The proportion of catastrophic SCIs is high when compared to other sports. SCIs in hockey occur most commonly from a collision with the boards due to intentional contact resulting in axial compression, as well as flexion-related teardrop fractures that lead to spinal canal compromise and neurologic injury. Public awareness programs, improvements in equipment, and rule changes can all serve to minimize the risk of SCI. Hockey has a relatively high rate of associated SCIs occurring most commonly due to flexion-distraction injuries from intentional contact. Further investigation into equipment and hockey arena characteristics as well as future research into injury recognition and removal from and return to play is necessary.

Review of Cerebrospinal Fluid Physiology and Dynamics: A Call for Medical Education Reform.

BACKGROUND: The flow of cerebrospinal fluid (CSF) has been described as a unidirectional system with the choroid plexus serving as the primary secretor of CSF and the arachnoid granulations as primary reabsorption site. This theory of neurosurgical forefathers has been universally adopted and taught as dogma. Many neuroscientists have found difficulty reconciling this theory with common pathologies, and recent studies have found that this "classic" hypothesis may not represent the full picture. OBJECTIVE: To review modern CSF dynamic theories and to call for medical education reform. METHODS: We reviewed the literature from January 1990 to December 2020. We searched the PubMed database using key terms "cerebrospinal fluid circulation," "cerebrospinal fluid dynamics," "cerebrospinal fluid physiology," "glymphatic system," and "glymphatic pathway." We selected articles with a primary aim to discuss either CSF dynamics and/or the glymphatic system. RESULTS: The Bulat-Klarica-Oreskovic hypothesis purports that CSF is secreted and reabsorbed throughout the craniospinal axis. CSF demonstrates similar physiology to that of water elsewhere in the body. CSF "circulates" throughout the subarachnoid space in a pulsatile to-and-fro fashion. Osmolarity plays a critical role in CSF dynamics. Aquaporin-4 and the glymphatic system contribute to CSF volume and flow by establishing osmolarity gradients and facilitating CSF movement. Multiple studies demonstrate that the choroid plexus does not play any significant role in CSF circulation. CONCLUSION: We have highlighted major studies to illustrate modern principles of CSF dynamics. Despite these, the medical education system has been slow to reform curricula and update learning resources.

Hannover Classification of Vestibular Schwannomas: A Reliability Study.

BACKGROUND: The Hannover classification of vestibular schwannomas is designed to stratify tumors based on extrameatal extension and compression of the brainstem. We have previously reported the reliability of the Koos system, but to date, no study has assessed the reliability of the similar Hannover classification. OBJECTIVE: We present an assessment of the intrarater and interrater reliability of the Hannover classification system. METHODS: After institutional review board approval was obtained, a cross-sectional group of the magnetic resonance imaging of 40 patients with vestibular schwannomas varying in size comprised the study sample. Four raters were selected to assign a Hannover grade to 50 total scans. Interrater and intrarater reliability was calculated and reported using Fleiss's kappa, Kendall's W, and intraclass correlation coefficient (ICC). RESULTS: Interrater observer reliability was found to be moderate when measured using Fleiss' kappa (0.49), extremely strong using Kendall's W (0.93), and excellent as calculated by ICC (0.88). The results were all statistically significant (P < 0.05). Intrarater reliability for Hannover grade ranged from 0.77 to 1.00 (substantial to perfect). By Kendall's W and ICC, all raters had near perfect or excellent agreement. The results were all statistically significant (P < 0.05). CONCLUSIONS: The Hannover classification is a reliable system for grading the size of vestibular schwannomas. This supports its continued use and previously published results of the literature in studies relying on this classification. Further studies are needed to evaluate its validity and determine its role in preoperative counseling and determining microsurgery and radiosurgery outcomes.

Are Regulations Safe? Reflections From Developing a Digital Cancer Decision-Support Tool.

PURPOSE: Informatics solutions to early diagnosis of cancer in primary care are increasingly prevalent, but it is not clear whether existing and planned standards and regulations sufficiently address patients' safety nor whether these standards are fit for purpose. We use a patient safety perspective to reflect on the development of a computerized cancer risk assessment tool embedded within a UK primary care electronic health record system. METHODS: We developed a computerized version of the CAncer Prevention in ExetER studies risk assessment tool, in compliance with the European Union's Medical Device Regulations. The process of building this tool afforded an opportunity to reflect on clinical concerns and whether current regulations for medical devices are fit for purpose. We identified concerns for patient safety and developed nine practical recommendations to mitigate these concerns. RESULTS: We noted that medical device regulations (1) were initially created for hardware devices rather than software, (2) offer one-shot approval rather than supporting iterative innovation and learning, (3) are biased toward loss-transfer approaches that attempt to manage the fallout of harm instead of mitigating hazards becoming harmful, and (4) are biased toward known hazards, despite unknown hazards being an expected consequence of health care as a complex adaptive system. Our nine recommendations focus on embedding less-reductionist and stronger system perspectives into regulations and standards. CONCLUSION: Our intention is to share our experience to support research-led collaborative development of health informatics solutions in cancer. We argue that regulations in the European Union do not sufficiently address the complexity of healthcare information systems with consequences for patient safety. Future standards and regulations should continue to follow a system-based approach to risk, safety, and accident avoidance.

The Validity of the Koos Classification System With Respect to Facial Nerve Function.

BACKGROUND: The Koos classification of vestibular schwannomas is designed to stratify tumors based on extrameatal extension and compression of the brainstem. Our prior study demonstrated excellent reliability. No study has yet assessed its validity. OBJECTIVE: To present a retrospective study designed to assess the validity of the Koos grading system with respect to facial nerve function following treatment of 81 acoustic schwannomas. METHODS: We collected data retrospectively from 81 patients with acoustic schwannomas of various Koos grades who were treated with microsurgical resection or stereotactic radiosurgery. House-Brackmann (HB) scores were used to assess facial nerve function and obtained at various time points following treatment. We generated Spearman's rho and Kendall's tau correlation coefficients along with a logistic regression curve. RESULTS: We found no significant difference in the presence or absence of facial dysfunction by Koos classification when looking at all patients. There was a positive but fairly weak correlation between HB score and Koos classification, which was only significant at the first postoperative clinic appointment. There was a statistically significant difference in the presence or absence of facial dysfunction between patients treated with surgery vs radiation, which we expected. We found no statistically significant difference when comparing surgical approaches. Logistic regression modeling demonstrated a poor ability of the Koos grading system to predict facial nerve dysfunction following treatment. CONCLUSION: The Koos grading system did not predict the presence of absence of facial nerve dysfunction in our study population. There were trends within subgroups that require further exploration.

Initial clinical characteristics of gravid severe acute respiratory syndrome coronavirus 2-positive patients and the risk of progression to severe coronavirus disease 2019.

BACKGROUND: Available data suggest that the obstetric population is particularly vulnerable to severe respiratory syndrome coronavirus 2 infection, with a variable clinical course leading to severe respiratory failure. However, established early warning scores designed to identify patients at risk of clinical deterioration were never validated in the obstetric population. OBJECTIVE: This retrospective cohort study sought to evaluate the initial clinical characteristics of pregnant patients diagnosed with severe acute respiratory syndrome coronavirus 2 infection and to develop a pregnancy-specific early warning score to identify patients at risk for clinical deterioration and requiring advanced respiratory support. STUDY DESIGN: This was a single center, retrospective cohort study of pregnant patients diagnosed with severe acute respiratory syndrome coronavirus 2 infection between April 2020 and December 2020. A total of 50 patients with severe acute respiratory syndrome coronavirus 2 infection between April 2020 and November 2020 were used to create the prediction model. Initial clinical characteristics identified at the time of diagnosis were compared between patients who required advanced respiratory support and those who were asymptomatic or had mild symptoms for those diagnosed during the period of April 2020 to November 2020. Risk factors associated with a requirement for advanced respiratory support were used to create the Obstetric Warning Score system. The Obstetric Warning Score system was then validated using 30 patients diagnosed with severe acute respiratory syndrome coronavirus 2 infection in December 2020. A receiver operating characteristic curve was generated to evaluate the test characteristics of the Obstetric Warning Score system compared with other scoring systems including the Early Warning Score, the National Early Warning Score 2, and the Maternal Early Warning Criteria. RESULTS: Women who required advanced respiratory support were more likely to present with dyspnea (100% vs 33.3%; P<.001), have a higher heart rate (113.4 beats per minute vs 93 beats per minute; P<.001), respiratory rate (23.5 breaths per minute vs 17.7 breaths per minute; P<.001), temperature (99.1°F vs 98.3°F; P=.004), and C-reactive protein level (7.4 mg/dL vs 2.4 mg/dL; P<.001). Furthermore, 88.2% of patients requiring advanced respiratory support showed chest x-ray findings consistent with pneumonia, compared with 20.0% of the patients not requiring advanced respiratory support (P<.001). All patients requiring advanced respiratory support presented with at least 1 coronavirus disease 2019 symptom, whereas only 51.5% of patients not requiring advanced respiratory support were symptomatic (P<.001). The Obstetrical Warning Score model allocated 1 point each for a hazard ratio of >100 beats per minute, temperature of >99.0°F, C-reactive protein level of >2.0 mg/dL, respiratory rate between 20 and 24 breaths per minute, complaints of dyspnea, and a positive chest x-ray. A respiratory rate of >24 breaths per minute was assigned 2 points. The area under the curve for the Obstetric Warning Score system was 0.97 compared with 0.72 for the Early Warning Score system, 0.92 for the National Early Warning Score 2 system, and 0.85 for the Maternal Early Warning Criteria system. An Obstetric Warning Score of ≥3 was predictive of a requirement for advanced respiratory support with a sensitivity of 100%, specificity 64%, and a positive predictive value of 36%. CONCLUSION: The Obstetric Warning Score system presents a validated method for providers to identify pregnant patients who are at risk for respiratory failure and a requirement for advanced respiratory support.

Adverse neonatal outcomes associated with pregestational diabetes mellitus in infants born preterm.

BACKGROUND: Pregestational diabetes mellitus is associated with a higher risk of adverse pregnancy outcomes. Based on the available data, it is unclear whether infants born preterm to mothers with pregestational diabetes mellitus are at a higher risk of adverse outcomes than other preterm infants. OBJECTIVE: This study aimed to quantify the neonatal complications associated with pregestational diabetes mellitus in infants born preterm. STUDY DESIGN: This was a retrospective cohort study of all nonanomalous singleton neonates born in Texas from 2006 to 2014. Analysis was limited to births between 24 and 36 weeks' gestation and excluded multiple births, stillbirths, fetal congenital anomalies, neonates born to mothers with gestational diabetes mellitus, and neonates born to mothers with chronic hypertension. Results were stratified by pregestational diabetes mellitus status. Neonatal outcomes of interest included infant death, neonatal intensive care unit admission, low 5-minute Apgar scores, assisted ventilation of >6 hours, surfactant administration, and seizures. Multivariate logistic regression analysis was performed to estimate the association between pregestational diabetes mellitus and neonatal outcomes controlling for potential confounding variables. RESULTS: After predefined exclusions, 277,210 births were analyzed, 4164 of which were to mothers with pregestational diabetes mellitus. The comparison group consisted of mothers without pregestational diabetes mellitus. The preterm infant mortality rates between the pregestational diabetic and nondiabetic groups were similar. However, after adjusting for confounding variables, there was an increased risk of infant mortality for preterm neonates born to mothers with pregestational diabetes mellitus. In infants born preterm, pregestational diabetes mellitus was associated with an increased risk of infant death, low 5-minute Apgar score, prolonged assisted ventilation, surfactant requirement, and neonatal intensive care unit admission. Neonates born before 34 weeks' gestation had an increased risk of assisted ventilation of >6 hours, neonatal intensive care unit admission, and seizure. Neonates born to mothers with pregestational diabetes mellitus in the late preterm period between 34 and 36 weeks' gestation had an increased risk of low Apgar score at 5 minutes, assisted ventilation of >6 hours, surfactant use, and neonatal intensive care unit admission. CONCLUSION: Pregestational diabetes mellitus is associated with a higher risk of adverse neonatal outcomes in infants born preterm.

A Bibliometric Analysis of Neurosurgical Practice Guidelines.

BACKGROUND: In the last 20 yr, the rate of neurosurgical guideline publication has increased. However, despite the higher volume and increasing emphasis on quality there remains no reliable means of measuring the overall impact of clinical practice guidelines (CPGs). OBJECTIVE: To utilize citation analysis to evaluate the dispersion of neurosurgical CPGs. METHODS: A list of neurosurgical guidelines was compiled by performing electronic searches using the Scopus (Elsevier, Amsterdam, Netherlands) and National Guideline Clearinghouse databases. The Scopus database was queried to obtain current publication and citation data for all included documents and categorized based upon recognized neurosurgical specialties. The h-index, R-index, h2-index, i10-index, and dissemination index (D-Index) were manually calculated for each subspecialty. RESULTS: After applying screening criteria the search yielded 372 neurosurgical CPGs, which were included for bibliometric analysis. The overall calculated h-index for neurosurgery was 56. When broken down by subspecialty trauma/critical care had the highest value at 35, followed by spine and peripheral nerve at 30, cerebrovascular at 28, tumor at 16, pediatrics at 14, miscellaneous at 11, and functional/stereotactic/pain at 6. Cerebrovascular neurosurgery was noted to have the highest D-Index at 3.4. CONCLUSION: A comprehensive framework is useful for guideline impact analysis. Bibliometric data provides a novel and adequate means of evaluating the successful dissemination of neurosurgical guidelines. There remains a paucity of data regarding implementation and clinical outcomes of individual guidelines.

Loss of consciousness at onset of aneurysmal subarachnoid hemorrhage in good-grade patients.

Loss of consciousness (LOC) at presentation with aneurysmal subarachnoid hemorrhage (aSAH) has been associated with early brain injury and poor functional outcome. The impact of LOC on the clinical course after aSAH deserves further exploration. A retrospective analysis of 149 aSAH patients who were prospectively enrolled in the Cerebral Aneurysm Renin Angiotensin Study (CARAS) between 2012 and 2015 was performed. The impact of LOC was analyzed with emphasis on patients presenting in excellent or good neurological condition (Hunt and Hess 1 and 2). A total of 50/149 aSAH patients (33.6%) experienced LOC at presentation. Loss of consciousness was associated with severity of neurological condition upon admission (Hunt and Hess, World Federation of Neurosurgical Societies (WFNS), Glasgow Coma Scale (GCS) grade), hemorrhage burden on initial head CT (Fisher CT grade), acute hydrocephalus, cardiac instability, and nosocomial infection. Of Hunt and Hess grade 1 and 2 patients, 21/84 (25.0%) suffered LOC at presentation. Cardiac instability and nosocomial infection were significantly more frequent in these patients. In multivariable analysis, LOC was the predominant predictor of cardiac instability and nosocomial infection. Loss of consciousness at presentation with aSAH is associated with an increased rate of complications, even in good-grade patients. The presence of LOC may identify good-grade patients at risk for complications such as cardiac instability and nosocomial infection.

Developing Physician Leadership in Hospital Policy Development: A Case Study of Resident-Driven Policy Initiatives in the Department of Neurosurgery at the University of Alabama at Birmingham.

The bulk of a resident's daily work is patient care related; however, other aspects of residency training are vital both to a resident's education and to the advancement of the field. Basic science and clinical research are the more common academic activities in which residents participate after completion of daily patient care objectives. Less frequently, residents participate in a process vital to the delivery of efficient, cost-effective, and safe patient care: hospital policy development. Two policies were identified as outdated or absent: (1) the process for the declaration of brain death and (2) a policy for the use of hypertonic saline in the Neurosciences Intensive Care Unit. The policies were rewritten after review of the existing policy (when applicable), other institutions' examples, national guidelines, and state and federal laws. Once written, proposals were reviewed by department leadership, hospital ethics, legal counsel, ad hoc specialty committees, the Medical Directors Council, and the Medical Executive Committee. After multiple revisions, each proposal was endorsed by the above bodies and ratified as hospital policy. Residents may make a substantial impact on patient care through active participation in the authorship and implementation of hospital policy. The inclusion of residents in policy development has improved the process for declaring brain death and management of patients with devastating neurological pathology. Resident involvement in hospital policy initiatives can be successful, valuable to the institution, and beneficial to patient care. Resident involvement is predicated on faculty and institutional support of such endeavors.

Reserved Bed Program Reduces Neurosciences Intensive Care Unit Capacity Strain: An Implementation Study.

BACKGROUND: Neurosciences intensive care units (NICUs) provide institutional centers for specialized care. Despite a demonstrable reduction in morbidity and mortality, NICUs may experience significant capacity strain with resulting supraoptimal utilization and diseconomies of scale. We present an implementation study in the recognition and management of capacity strain within a large NICU in the United States. Excessive resource demand in an NICU creates significant operational issues. OBJECTIVE: To evaluate the efficacy of a Reserved Bed Pilot Program (RBPP), implemented to maximize economies of scale, to reduce transfer declines due to lack of capacity, and to increase transfer volume for the neurosciences service-line. METHODS: Key performance indicators (KPIs) were created to evaluate RBPP efficacy with respect to primary (strategic) objectives. Operational KPIs were established to evaluate changes in operational throughput for the neurosciences and other service-lines. For each KPI, pilot-period data were compared to the previous fiscal year. RESULTS: RBPP implementation resulted in a significant increase in accepted transfer volume to the neurosciences service-line (P = .02). Transfer declines due to capacity decreased significantly (P = .01). Unit utilization significantly improved across service-line units relative to theoretical optima (P < .03). Care regionalization was achieved through a significant reduction in "off-service" patient placement (P = .01). Negative externalities were minimized, with no significant negative impact in the operational KPIs of other evaluated service-lines (P = .11). CONCLUSION: Capacity strain is a significant issue for hospital units. Reducing capacity strain can increase unit efficiency, improve resource utilization, and augment service-line throughput. RBPP implementation resulted in a significant improvement in service-line operations, regional access to care, and resource efficiency, with minimal externalities at the institutional level.

Practice patterns in the conservative treatment of carpal tunnel syndrome: Survey results from members of the American Society of Hand Therapy.

STUDY DESIGN: A cross-sectional descriptive design was used. INTRODUCTION: Carpal tunnel syndrome (CTS) is a complex combination of symptoms resulting from compression of the median nerve within the carpal tunnel. A study that compares the conservative interventions identified in the literature with the actual conservative interventions being implemented by therapists for the treatment of CTS is not presently available. PURPOSE OF THE STUDY: The purpose of this study was to examine conservative interventions for CTS as reported by certified hand therapists (CHTs) within various clinical settings. The study also aimed to identify the decision-making process for the selection of CTS interventions. METHOD: CHT members of the American Society of Hand Therapists were surveyed electronically to obtain quantitative data. RESULTS: Patient education, nocturnal orthosis, and ergonomic modifications ranked among the top conservative interventions utilized for CTS, whereas treatments such as magnet therapy, C-TRAC, and heating lamps ranked among the least utilized interventions. When selecting interventions, clinical expertise, research evidence, and patient preferences were all highly valued considerations for CHT. DISCUSSION: Our study offers a unique summary of CHT practice patterns for CTS interventions and the associated decision-making processes. It compares findings with existing literature on this topic, offering researchers and clinicians a glimpse of the CTS practice trends. CONCLUSION: This study may serve to prioritize future research studies based on the prevalence of intervention usage among the experts. It also serves as a guide to those seeking to understand the most common interventions utilized for conservative CTS treatment.
