How academia can help to grow-and sustain-a robust nursing workforce

This panel paper is the second installment in a six-part Nursing Outlook special edition based on the 2022 Emory Business Case for Nursing Summit. The 2022 summit convened national nursing, health care, and business leaders to explore possible solutions to nursing workforce crises, including the nursing shortage. Each of the summit's four panels authored a paper in the special edition on their respective topic(s), and this panel paper focuses on the topic of nursing workforce growth. It discusses priority areas for academia to help ameliorate nursing shortages, including through changes to nursing curricula and/or programming, greater attention to nursing financial needs (including nursing student loans), and regulatory reforms.

Addressing Veteran Health-Related Social Needs: How Joint Commission Standards Accelerated Integration and Expansion of Tools and Services in the Veterans Health Administration

BACKGROUND

The Joint Commission recently named reduction of health care disparities and improvement of health care equity as quality and safety priorities (Leadership [LD] Standard LD.04.03.08 and National Patient Safety Goal [NPSG] Standard NPSG.16.01.01). As the largest integrated health system, the Veterans Health Administration (VHA) sought to leverage these new accreditation standards to further integrate and expand existing tools and initiatives to reduce health care disparities and address health-related social needs (HRSNs).

INITIATIVES AND TOOLS

A combination of existing data tools (for example, Primary Care Equity Dashboard), resource tools (for example, Assessing Circumstances and Offering Resources for Needs tool), and a care delivery approach (for example, Whole Health) are discussed as quality improvement opportunities to further integrate and expand how VHA addresses health care disparities and HRSNs. The authors detail the development timeline, building, limitations, and future plans for these tools and initiatives.

COORDINATION OF INITIATIVES

Responding to new health care equity Joint Commission standards led to new implementation strategies and deeper partnerships across VHA that facilitated expanded dissemination, technical assistance activities, and additional resources for VHA facilities to meet new standards and improve health care equity for veterans. Health care systems may learn from VHA's experiences, which include building actionable data platforms, employing user-centered design for initiative development and iteration, designing wide-reaching dissemination strategies for tools, and recognizing the importance of providing technical assistance for stakeholders.

FUTURE DIRECTIONS

VHA continues to expand implementation of a diverse set of tools and resources to reduce health care disparities and identify and address unmet individual veteran HRSNs more widely and effectively.

Efferent limb stimulation prior to loop ileostomy closure: a systematic review and meta-analysis

BACKGROUND

Postoperative ileus (POI) remains a common phenomenon following loop ileostomy closure. Our aim was to determine whether preoperative physiological stimulation (PPS) of the efferent limb reduced POI incidence.

METHODS

A PRISMA-compliant meta-analysis searching PubMed, EMBASE and CENTRAL databases was performed. The last search was carried out on 30 January 2023. All randomized studies comparing PPS versus no stimulation were included. The primary endpoint was POI incidence. Secondary endpoints included the time to first passage of flatus/stool, time to resume oral diet, need for nasogastric tube (NGT) placement postoperatively, length of stay (LOS) and other complications. Random effects models were used to calculate pooled effect size estimates. Trial sequential analyses (TSA) were also performed.

RESULTS

Three randomized studies capturing 235 patients (116 PPS, 119 no stimulation) were included. On random effects analysis, PPS was associated with a quicker time to resume oral diet (MD - 1.47 days, 95% CI - 2.75 to - 0.19, p = 0.02), shorter LOS (MD - 1.47 days, 95% CI - 2.47 to - 0.46, p = 0.004) (MD - 1.41 days, 95% CI - 2.32 to - 0.50, p = 0.002, I2 = 56%) and fewer other complications (OR 0.42, 95% CI 0.18 to 1.01, p = 0.05). However, there was no difference in POI incidence (OR 0.35, 95% CI 0.10 to 1.21, p = 0.10), the requirement for NGT placement (OR 0.50, 95% CI 0.21 to 1.20, p = 0.12) or time to first passage of flatus/stool (MD - 0.60 days, 95% CI - 1.95 to 0.76, p = 0.39). TSA revealed imprecise estimates for all outcomes (except LOS) and further studies are warranted to meet the required information threshold.

CONCLUSIONS

PPS prior to stoma closure may reduce LOS and postoperative complications albeit without a demonstrable beneficial effect on POI. Further high-powered studies are required to confirm or refute these findings.

Defining the safety of early ileostomy closure after ileal pouch anal anastomosis

PURPOSE

The safety of early ileostomy reversal after ileal pouch anal anastomosis (IPAA) has not been established. Our hypothesis was that ileostomy reversal before 8 weeks is associated with negative outcomes.

METHODS

This was a retrospective cohort study from a prospectively maintained institutional database. Patients who underwent primary IPAA with ileostomy reversal between 2000 and 2021 from a Pouch Registry were stratified on the basis of timing of reversal. Those reversed before 8 weeks (early) and those reversed from 8 weeks to 116 days (routine) were compared. The primary outcome was overall complications according to timing and reason for closure.

RESULTS

Ileostomy reversal was performed early in 92 patients and routinely in 1908. Median time to closure was 49 days in the early group and 93 days in the routine group. Reasons for early reversal were stoma-related morbidity in 43.3% (n = 39) and scheduled closure in 56.7% (n = 51). The complication rate in the early group was 17.4% versus 11% in the routine group (p = 0.085). When early patients were stratified according to reason for reversal, those reversed early for stoma-related morbidity had an increased complication rate compared to the routine group (25.6% vs. 11%, p = 0.006). Patients undergoing scheduled reversal in the early group did not have increased complications (11.8% vs. 11%, p = 0.9). There was a higher likelihood of pouch anastomotic leak when reversal was performed early for stoma complications compared to routinely (OR 5.13, 95% CI 1.01-16.57, p = 0.049).

CONCLUSIONS

Early closure is safe but could be delayed in stoma morbidity as patients may experience increased complications.

What is the real morbidity after emergency colectomy for Crohn's disease? A propensity score matched study

BACKGROUND

In the inflammatory bowel disease literature, emergency surgery for Crohn's disease (CD) is associated with worse postoperative outcomes as compared to elective surgery. Previous studies have compared heterogeneous groups only. We hypothesized that this association would be lost after matched analysis. We aimed to compare matched CD patients undergoing elective vs emergency surgery.

METHODS

The National Surgical Quality Improvement database (01/2005-12/2019) was utilized to identify adult CD surgical patients. Univariate and conditional logistic regression models were used to analyze unmatched and matched cohorts. Propensity-score matching was performed to match emergency to non-emergency patients 1:1. Our primary outcome was a composite of any complication. Our secondary endpoints were hospital readmission, unplanned reoperation and 30-day morbidity and mortality.

RESULTS

In the unmatched analyses (n = 12,181/95.28% elective and n = 603/4.72% emergency) of Crohn's patients undergoing colectomy, 20% of elective and 42% of emergency patients experienced a complication (p < 0.001). Over 20 outcomes measured including length of stay (LOS), readmission, infections and respiratory, cardiovascular and renal complications, were worse in the emergency cohort. In the matched analyses (n = 400 emergency/400 elective patients) only the categories of any complication (OR 1.44, 1.06-1.96 95% CI, p = 0.02), any surgical site infection (SSI, OR 1.53, 1.07-2.19 95% CI, p = 0.02), superficial SSI (OR 2.25, 1.14-4.44 95% CI, p = 0.02), organ space SSI (1.58 OR 1.04-2.4 95% CI, p = 0.03), unplanned intubation (OR 5.0, 1.45-17.27 95% CI, p = 0.01), ventilation > 48 h (OR 9.0, 1.4-38.79 95% CI, p = 0.003) and septic shock (OR 4.5, 1.86-10.9 95% CI, p < 0.001) were higher in the emergency cohort.

CONCLUSIONS

Matching CD patients resulted in a loss of the observed increase in cardiovascular and renal complications, reoperation and LOS following emergency surgery; however, SSIs and respiratory complications remained increased despite matching.

341 ROLE AND TOLERANCE OF LUMBAR PUNCTURE TESTS FOR CSF BIOMARKERS OF ALZHEIMER'S DEMENTIA IN A SPECIALIZED MEMORY CLINIC

Background

People living with mild cognitive symptoms often require clarity on the underlying aetiology of their symptoms, and with the advent of disease modifying therapies for Alzheimer’s Disease (AD), establishing diagnostic accuracy for amyloid and tau pathology in AD will become more clinically relevant. CSF biomarker analysis via Lumbar Puncture (LP) is the most accurate and cost-effective means of establishing AD pathology. This study aimed to assess memory clinic patients’ tolerance of LP as a diagnostic tool in the work-up of memory symptoms.

Methods

A consecutive sample of patients offered CSF analysis as part of their diagnostic plan in a tertiary memory service of a University Teaching Hospital were included. After clinician discussion, an LP for AD biomarker detection is offered to all patients with amnestic/non-amnestic mild cognitive impairment, or those with atypical motor-cognitive symptoms in this service.

Results

119 patients offered an LP from 2019-2020 were contacted, fifty-four (45%) of whom participated in this study. The average age was 70.1 (±7.5) years, 50% female. Forty-two (42/54, 78%) had an LP performed. More women declined an LP than men (8/12, 66%). Almost all of those who had an LP, (38/42, 90.4%) thought it yielded useful information and would recommend it for others. Side effects included mild back pain relieved with simple analgesia (11/42, 26%) and headache (3/42, 7%). There were no incidences of neurological sequelae or requirements for dural patch. Of the 12/54 (22%) who declined CSF analysis; reasons for same were pre-existing back pain (3/12, 25%), needle-phobia (3/12, 25%), and only 2/12, (16%) declined because they did not wish to know the results of the investigation.

Conclusion

This study highlights high levels of acceptance of CSF analysis when offered as part of routine care, with infrequent side effects. Most patients found the clinical information yielded was useful.

1003 UTILITY AND TOLERABILITY OF CSF AD BIOMARKERS IN A GERIATRICIAN-LED MEMORY SERVICE

Introduction

People with mild cognitive symptoms often require diagnostic clarity and with the advent of disease modifying therapies for Alzheimer’s disease (ad), establishing diagnostic accuracy for amyloid and tau pathology in ad will become more clinically relevant. CSF biomarker analysis via lumbar puncture (LP) is the most accurate and cost-effective means of establishing ad pathology. Despite their clinical validation, few centres offer LP biomarker analysis, frequently citing patient intolerance and reluctance as factors. This study aimed to assess memory clinic patients’ tolerance of LP as a diagnostic tool in the work-up of memory symptoms.

Method

A consecutive sample of patients offered CSF analysis as part of their diagnostic plan in a tertiary memory service of a University Teaching Hospital were included. After clinician discussion, an LP for ad biomarker detection is offered to all patients with amnestic/non-amnestic mild cognitive impairment, or those with atypical motor-cognitive symptoms in this service.

Results

119 patients offered an LP from 2019–2020 were contacted, fifty-four (45%) of whom participated in this study. The average age was 70.1 (±7.5) years, 50% female. Forty-two (42/54, 78%) had an LP performed. More women declined an LP than men (8/12, 66%). Almost all of those who had an LP, (38/42, 90.4%) thought it yielded useful information.

Conclusion

This study highlights high levels of acceptance of CSF analysis when offered as part of routine care, with infrequent side effects. Most patients found the clinical information yielded was useful.

Developing and Implementing Predictive Models in a Learning Healthcare System: Traditional and Artificial Intelligence Approaches in the Veterans Health Administration

Predicting clinical risk is an important part of healthcare and can inform decisions about treatments, preventive interventions, and provision of extra services. The field of predictive models has been revolutionized over the past two decades by electronic health record data; the ability to link such data with other demographic, socioeconomic, and geographic information; the availability of high-capacity computing; and new machine learning and artificial intelligence methods for extracting insights from complex datasets. These advances have produced a new generation of computerized predictive models, but debate continues about their development, reporting, validation, evaluation, and implementation. In this review we reflect on more than 10 years of experience at the Veterans Health Administration, the largest integrated healthcare system in the United States, in developing, testing, and implementing such models at scale. We report lessons from the implementation of national risk prediction models and suggest an agenda for research. Expected final online publication date for the Annual Review of Biomedical Data Science, Volume 5 is August 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

695 QUALITY IMPROVEMENT PROJECT ON TRANSFER TIMES OF ACUTE HIP FRACTURE PATIENTS FROM ED TO INPATIENT BED POST SIMULATION TRAINING

Introduction

The care of patients with hip fractures is a surrogate marker of trauma care. Irish hip Fracture Standard (IHFS) 1 involves patients with a hip fracture being admitted to an orthopaedic ward bed within 4 hours of attending the ED. We wanted to audit our current practice and introduce a quality improvement project to improve the timeliness and efficiency of care of our hip fracture patients compared with the gold standard IHFS 1. We introduced a 90 minute multidisciplinary simulation training programme on the hip fracture pathway to our ED in February 2021. All key stakeholders were represented; from Emergency Medicine, Orthopaedics, Nursing (EM and Orthopaedic), Radiology, Radiography, Porters (32 people overall). Because of covid-19, the training was available in person and online via zoom.

Methods

We performed a retrospective audit of patients presenting to TUH ED with a proximal third of femur fracture between 4th February and 31st March inclusive in 2020 and 2021, pre and post introduction of multidisciplinary simulation based medical education on the hip fracture pathway. Data was collected from the electronic record database (symphony). We recorded the following data;

Results

2020 n = 31 Average time to ward—8 hrs 29 mins. 26% patients reached ward <4 hours. (8/31) 2021 n = 25 Average time to ward—5 hrs 58 mins (32% reduction vs 2020) 72% patients reached ward <4 hours. (18/25) (46% increase vs 2020).

Conclusion

Simulation based medical education is a successful intervention to improve compliance with our hip fracture pathway, time from presentation to transfer to an orthopaedic ward bed and achieve IHFS 1.

Assessment of the microbial load of airway clearance devices used by a cohort of children with cystic fibrosis

Background

Positive expiratory pressure (PEP) devices are an important element of the management of cystic fibrosis, and of other respiratory diseases. Whereas there have been reports in the literature of contamination of airway clearance devices and their surfaces by microbial pathogens, there is little evidence available regarding such contamination and its contribution to respiratory infection.

Aim

To establish whether pathogenic bacteria can contaminate PEP devices in the context of normal cleaning and maintenance practices.

Methods

Patients' home-use clearance devices were brought to a routine clinic appointment and collected for microbiology sampling and analysis. The patients were provided with replacement devices. Nineteen such devices were collected from 17 patients, reflecting use of multiple devices by some patients. Swabs were taken and cultured from each patient's used device, the patient's airway, as well as from new unopened and unused devices that acted as controls.

Results

Seven of 19 devices (37%) tested positive for presence of pathogenic bacteria. Device-cleaning methods varied among patients and non-sterilization methods were found to be ineffective at removing pathogens. Microbial species found on the devices did not correlate with those identified from airway swabs.

Conclusion

This study demonstrates the presence of pathogens on positive expiratory pressure devices. The potential for transmission of these pathogens to the patient's airway and the risk of infection remains unclear and requires further study.

Creating World-Class Care and Service for Our Nation's Finest: How Veterans Health Administration Diffusion of Excellence Initiative Is Innovating and Transforming Veterans Affairs Health Care

As the largest integrated health care system in the US, the Veterans Health Administration is dedicated to continually innovating its systems, technology, and practices to provide high-quality care to US veterans. In this article, I describe the Veterans Health Administration's Diffusion of Excellence Initiative, which involves an annual, systemwide competition to recognize Department of Veterans Affairs employees and identify promising practices for implementation in other Department of Veterans Affairs facilities or Veterans Integrated Service Networks. To demonstrate the reach and impact of the initiative, I highlight practices that are being implemented in 4 areas: 1) direct scheduling, 2) access to health care in rural areas, 3) access to mental health care, and 4) interactive and patient-centered care. In addition, I outline the primary components of the current transition plan to elevate lessons learned and transform the initiative from a nascent start-up to a sustainable part of the Veterans Health Administration's culture.

Diffusion of Excellence: Accelerating the Spread of Clinical Innovation and Best Practices across the Nation's Largest Health System

The time it takes for clinical innovation and evidence-based practices to reach patients remains a major challenge for the health care sector. In 2015, the Veterans Health Administration (VHA) launched the Diffusion of Excellence Initiative aimed at aligning organizational resources with early-stage to midstage promising practices and innovations to replicate, scale, and eventually spread those with greatest potential for impact and positive outcomes. Using a 5-step systematic approach refined over time, frontline VHA staff have submitted more than 1676 practices since the initiative's inception, 47 of which have been selected as high-impact, Gold Status practices. These Gold Status practices have been replicated more than 412 times in Veterans Affairs hospitals across the country, improving care for more than 100,000 veterans and approximately $22.6 million in cost avoidance for the VHA. More importantly, practices such as Project HAPPEN (Hospital-Acquired Pneumonia Prevention by Engaging Nurses to complete oral care) and rapid availability of intranasal naloxone have saved veterans' lives. Several practices are now being implemented across the country, and the Diffusion of Excellence Initiative is playing a pivotal role as the VHA works to modernize its health care system. This initiative serves as a promising model for other health care systems seeking to accelerate the spread and adoption of clinical innovation and evidence-based practices.

Comparison of Wait Times for New Patients Between the Private Sector and United States Department of Veterans Affairs Medical Centers

IMPORTANCE

Concerns have been raised about the adequacy of health care access among patients cared for within the United States Department of Veterans Affairs (VA) health care system.

OBJECTIVES

To determine wait times for new patients receiving care at VA medical centers and compare wait times in the VA medical centers with wait times in the private sector (PS).

DESIGN, SETTING, AND PARTICIPANTS

A retrospective, repeated cross-sectional study was conducted of new appointment wait times for primary care, dermatology, cardiology, or orthopedics at VA medical centers in 15 major metropolitan areas in 2014 and 2017. Comparison data from the PS came from a published survey that used a secret shopper survey approach. Secondary analyses evaluated the change in overall and unique patients seen in the entire VA system and patient satisfaction survey measures of care access between 2014 and 2017.

MAIN OUTCOMES AND MEASURES

The outcome of interest was patient wait time. Wait times in the VA were determined directly from patient scheduling. Wait times in the PS were as reported in Merritt Hawkins surveys using the secret shopper method.

RESULTS

Compared with the PS, overall mean VA wait times for new appointments in 2014 were similar (mean [SD] wait time, 18.7 [7.9] days PS vs 22.5 [7.3] days VA; P = .20). Department of Veterans Affairs wait times in 2014 were similar to those in the PS across specialties and regions. In 2017, overall wait times for new appointments in the VA were shorter than in the PS (mean [SD], 17.7 [5.9] vs 29.8 [16.6] days; P < .001). This was true in primary care (mean [SD], 20.0 [10.4] vs 40.7 [35.0] days; P = .005), dermatology (mean [SD], 15.6 [12.2] vs 32.6 [16.5] days; P < .001), and cardiology (mean [SD], 15.3 [12.6] vs 22.8 [10.1] days; P = .04). Wait times for orthopedics remained longer in the VA than the PS (mean [SD], 20.9 [13.3] vs 12.4 [5.5] days; P = .01), although wait time improved significantly between 2014 and 2017 in the VA for orthopedics while wait times in the PS did not change (change in mean wait times, increased 1.5 days vs decreased 5.4 days; P = .02). Secondary analysis demonstrated an increase in the number of unique patients seen and appointment encounters in the VA between 2014 and 2017 (4 996 564 to 5 118 446, and 16 476 461 to 17 331 538, respectively), and patient satisfaction measures of access also improved (satisfaction scores increased by 1.4%, 3.0%, and 4.0% for specialty care, routine primary care, and urgent primary care, P < .05).

CONCLUSIONS AND RELEVANCE

Although wait times in the VA and PS appeared to be similar in 2014, there have been interval improvements in VA wait times since then, while wait times in the PS appear to be static. These findings suggest that access to care within the VA has improved over time.

Surgical management of a giant hepatic cyst with suspicious radiological features

Cysts in the liver have a wide variety of aetiologies. Important features of malignancy based on various imaging techniques must be considered prior to any intervention. Perioperative decision making in complex or difficult cysts is key to appropriate patient management. A 66-year-old woman was referred to the outpatient department with a one-year history of intermittent, sharp, right upper quadrant pain, radiating to her back. Computed tomography and magnetic resonance imaging showed a large cyst in the right and left lobes of the liver with portal inflow closely related. Features such as wall thickening suspicious for cystadenocarcinoma were present. An open resection was planned but, based on perioperative findings, the cyst had features making it unsafe to perform excision. De-roofing, carefully controlled drainage and assessment of the internal aspect of the cyst were performed, which revealed an extremely close relationship to portal inflow. This case describes the decision-making process when faced with complex indeterminate pathology of the liver and proximity of critical structures.

An Evaluation of the First Public Health Service Primary Care Policy Fellowship

In June 1991, the U.S. Public Health Service sponsored a 3-week Primary Care Policy Fellowship to establish an interdisciplinary cadre of primary care leaders. The fellowship was designed to introduce senior-level practitioners, academicians, researchers, and adrninistrators to the dynamics of primary care policy development, the legislative process, and resource identification. An evaluation was conducted to determine expectations and reasons whyfellows participated in the fellowship, analyze the degree ofperceived learning, identify the sessions of most value, and describe the personal goals achieved by thefellows relating to their future leadership responsibilities in primary care. The 18 fellows most highly valued the networking across primary care disciplines, the sessions with constituency groups, and discussions about influencing decision makers. The leadership skills development activities particularly met their expectations. Theirskills were improved in identifying ways to influence policymakers, in locating resources for primary care research, and in networking with primary care leaders.

Entero-enteric fistula from the stump of an end-to-side ileocolic anastomosis mimicking cancer recurrence

Enteric fistulae are a complex and technically frustrating complication of any bowel surgery. The constellation of associated non-specific symptoms often leads to extensive investigation and, in this case, suspicion of disease recurrence. A 71-year-old gentleman with a history of previous colorectal cancer presented with chronic diarrhoea, weight loss and left lower quadrant pain. Elective exploratory laparoscopy was performed to investigate possible disease recurrence due to elevated carcinoembryonic antigen levels and a positron emission tomography positive area within the mesentery. A jejunal-ileal fistula was found at laparotomy where the blind ileal stump of the end-to-side ileocolic anastomosis had fistulated into the jejunum. Resection of the affected jejunum was performed with end-to-end jejuno-jejunal re-anastomosis and stapling of the ileal stump. Specimen histology was negative for recurrence. Intestinal fistulae represent a diagnostic challenge. This is the first case report describing an enteric fistula mimicking cancer recurrence.

A meta-analysis to determine the oncological implications of conversion in laparoscopic colorectal cancer surgery

AIM

Laparoscopic colon and rectal cancer surgery is oncologically equivalent to open resection, but the impact of conversion is undetermined. The aim of this study was to assess the oncological outcome and predictive factors associated with conversion.

METHOD

A comprehensive search for published studies examining the associated factors and outcome of conversion from laparoscopic to open colorectal cancer resection was performed adhering to PRISMA (Preferred Reporting Items in Systematic Reviews and Meta-analyses) guidelines. Only randomized control trials and prospective studies were included. Each study was reviewed and the data extracted. Random effects methods were used to combine data.

RESULTS

Fifteen studies, including 5293 patients, met the inclusion criteria. Of these 4391 patients had a completed laparoscopic resection and 902 were converted to an open resection. The average conversion rate of the studies was 17.9 ± 10.1%. Meta-analysis showed completed laparoscopic surgery favoured lower 30-day mortality (OR 0.134, 95% CI 0.047-0.385, P < 0.0001), lower long-term disease recurrence (OR 0.634, 95% CI 0.421-0.701, P < 0.023) and lower overall mortality (OR 0.512, 95% CI 0.417-0.629, P < 0.0001). Factors negatively associated with completion of laparoscopic surgery were male gender (P = 0.011), rectal tumour (P = 0.017), T3/T4 tumour (P = 0.009) and node-positive disease (P = 0.009). Completed laparoscopic surgery was also associated with a lower body mass index (BMI; mean difference -0.93 kg/m(2) , P = 0.004).

CONCLUSION

The results suggest that conversion from laparoscopic to open colorectal cancer resection is influenced by patient and tumour characteristics and is associated with an adverse perioperative outcome. Although confounding factors such as advanced tumour stage and elevated BMI are present, unsuccessful laparoscopic surgery appears to be associated with an adverse long-term oncological outcome.

Reasons for recall following conditional discharge: explanations given by male patients suffering from dual diagnosis in a London Forensic Unit

Patients who have been discharged from forensic services often have conditions they have to abide by as part of their discharge, and failure to do so leads to recall. We interviewed six men who had been conditionally discharged from forensic services and then been recalled into hospital to find out what they thought went wrong. The reasons they gave for why things went wrong included feeling that the system was unfair and made them feel like criminals even though they did not feel they had put anyone at risk. Some of them were not fully aware of the conditions they needed to adhere to, and some of them had breached the conditions but did not take responsibility for what had happened. In addition, supervision was felt to be very controlling and disruptive rather than supportive when patients were often lonely, bored and needing support. Most participants reported that they experienced poor standards of aftercare in hostels they were required to reside in. In the future, care of patients after conditional discharge should include better communication between patients and their supervisory team, recognition of the need for more support and improvements in the standards of care in hostels, as well as a collaborative approach to risk assessment that might reduce the frequency of relapse and readmission. This study explores how male patients suffering from dual diagnosis in a forensic unit perceive being recalled and readmitted following conditional discharge and their views about how services might be improved. A qualitative approach was used drawing on grounded theory techniques. Audiotaped semistructured interviews collected data from a purposefully selected sample of six participants who had been recalled and met the inclusion criteria of the study. Data were analysed using the constant comparative method. Most participants perceived the recall system as unfair, inappropriately criminalized their behaviour and was based on an assessment of risk that they did not understand or accept. Participants were not fully aware of the conditions of their discharge, and most did not accept responsibility for their role in being recalled and blamed the system. Care following discharge was rarely seen as positive, and poor standards in hostels were reported by most participants. Supervision was often seen as disruptive and controlling, and focused more on surveillance rather than support. Better communication might have helped them understand and adhere to the conditions of their discharge. Participants identified the importance of family and friends to their recovery, the importance of having their own accommodation, and the need to be more independent.

Laboratory test costs: attitudes and awareness among staff in a regional hospital

There continues to be an unrelenting rise in the volumes of laboratory tests ordered in medicine, which is both expensive and has the potential for over-investigation. We performed a quantitative, observational, cross-sectional study of staff with the authority to initiate a laboratory test, using a voluntary, anonymous questionnaire. Our aim was to assess the awareness of and attitudes towards laboratory test costs. 226 surveys were completed over 2 weeks in June, 2012. Most numerous respondents were Staff nurses 125 (55.3%) followed by senior house officers (SHOs) 26 (11.5%) and clinical nurse managers/specialists (CNMs and CNSs) 23 (10.2%). The majority of staff, 191(85.6%), felt unaware of the cost of laboratory tests, which they ordered. For non urgent tests, the majority of respondents, 136 (61.8%) felt cost was either quite of very important. For urgent tests, the majority of respondents, 188 (84.6%) felt cost was of minor or of no importance. Doctors felt more aware of costs than nurses (26.9% vs. 9.3%) and doctors test cost estimates were correct more often than nurses (33% vs. 21%). The results indicate poor awareness of laboratory test cost amongst doctors and nurses. Given the expenditure incurred by a rise in the volume of tests and the potential for over-investigation for patients, strategies for improving the awareness of and attitudes towards laboratory tests need to be developed.

Implementing health reform: improved data collection and the monitoring of health disparities

The relative lack of standards for collecting data on population subgroups has not only limited our understanding of health disparities, but also impaired our ability to develop policies to eliminate them. This article provides background about past challenges to collecting data by race/ethnicity, primary language, sex, and disability status. It then discusses how passage of the Affordable Care Act has provided new opportunities to improve data-collection standards for the demographic variables of interest and, as such, a better understanding of the characteristics of populations served by the U.S. Department of Health and Human Services (HHS). The new standards have been formally adopted by the Secretary of HHS for application in all HHS-sponsored population health surveys involving self-reporting. The new data-collection standards will not only promote the uniform collection and utilization of demographic data, but also help the country shape future programs and policies to advance public health and to reduce disparities.

BRAF mutation is associated with distinct clinicopathological characteristics in colorectal cancer: a systematic review and meta-analysis

AIM

Colorectal cancer is a heterogeneous disease with multiple underlying genetic mutations resulting in different phenotypes. Mutation in the v-Raf murine sarcoma viral oncogene homolog B1 (BRAF) proto-oncogene is an important event in the methylator pathway. There is no consensus, however, on the clinicopathological characteristics associated with BRAF mutation.

METHOD

A comprehensive search for published studies examining the effect of BRAF mutation on colorectal cancer was performed. Random effects methods were used to combine data.

RESULTS

Data were retrieved from 21 studies describing 9885 patients. BRAF associated colorectal cancer is associated with proximal tumour location (OR 5.222, 95% CI 3.801-7.174, P < 0.001), T4 tumours (OR 1.761, 95% CI 1.164-2.663, P = 0.007) and poor differentiation (OR 3.816, 95% CI 2.714-5.365, P < 0.001) and is negatively associated with male sex (OR 0.623, 95% CI 0.505-0.769, P < 0.001), age of diagnosis under 60 years (OR 0.453, 95% CI 0.280-0.733, P = 0.001) and rectal cancer (OR 0.266, 95% CI 0.122-0.422, P < 0.001).

CONCLUSION

BRAF mutation appears to be associated with distinct, unfavourable clinicopathological characteristics in colorectal cancer.

Investigation of the migration of triclabendazole residues to milk products manufactured from bovine milk, and stability therein, following lactating cow treatment

Triclabendazole (TCB) is a flukicide used in the treatment of liver fluke in cattle; however, its use is currently prohibited in lactating dairy cows. In this study, following administration of 10% Fasinex (triclabendazole, Novartis Animal Health UK Ltd., Camberley, UK) the milk of 6 animals was used to manufacture dairy products, to ascertain if TCB residues in milk migrate into dairy products. The detection limit of the ultra-high-performance liquid chromatography-tandem mass spectrometry method used was 0.67 μg/kg. The highest concentrations of TCB residue measured, within the individual cow milk yield, was 1,529 ± 244 µg/kg (n=6), on d 2 posttreatment. Days 2 and 23 posttreatment represented high and low residue concentrations, respectively. At each of these 2 time points, the milk was pooled into 2 independent aliquots and refrigerated. Milk products, including cheese, butter, and skim milk powder were manufactured using pasteurized and unpasteurized milk from each aliquot. The results for high residue milks demonstrated that TCB residues concentrated in the cheese by a factor of 5 (5,372 vs. 918 µg/kg for cheese vs. milk) compared with the starting milk. Residue concentrations are the sum of TCB and its metabolites, expressed as keto-TCB. Residues were concentrated in the butter by a factor of 9 (9,177 vs. 1,082 μg/kg for butter vs. milk) compared with the starting milk. For milk, which was separated to skim milk and cream fractions, the residues were concentrated in the cream. Once skim milk powder was manufactured from the skim milk fraction, the residue in powder was concentrated 15-fold compared with the starting skim milk (7,252 vs. 423 µg/kg for powder vs. skim milk), despite the high temperature (185 °C) required during powder manufacture. For products manufactured from milk with low residue concentrations at d 23 posttreatment, TCB residues were detected in butter, cheese, and skim milk powder, even though there was no detectable residue in the milk used to manufacture these products. Triclabendazole residues were concentrated in some milk products (despite manufacturing treatments), exceeding residue levels in the starting milk and, depending on the storage conditions, may be relatively stable over time.

Diagnosing peritoneal tuberculosis

A 37-year-old male healthcare worker presented to the medical assessment unit complaining of a 3-month history of lethargy, weight loss, night sweats and intermittent abdominal discomfort. On examination there was some dullness to percussion at the right lung base and decreased breath sounds. He had mild generalised tenderness in his abdomen. Blood tests were normal. Chest x-ray and CT of the thorax showed small bilateral pleural effusions with no other abnormality. CT of the abdomen and pelvis however, showed ascites with extensive thickening of the peritoneum and marked induration of the mesentery and omentum. Mantoux test was positive. Laparoscopy was undertaken to outrule intra-abdominal malignancy and confirmed the diagnosis of tuberculosis. Peritoneal wall biopsies were taken from which Mycobacterium was isolated confirming peritoneal tuberculosis. He was started on rifampicin, isoniazid, pyrazinamide and ethambutol and completed a 6-month course without further complications.

Impact of the fall 2009 influenza A(H1N1)pdm09 pandemic on US hospitals

BACKGROUND

Understanding how hospitals functioned during the 2009 influenza A(H1N1)pdm09 pandemic may improve future public health emergency response, but information about its impact on US hospitals remains largely unknown.

RESEARCH DESIGN

We matched hospital and emergency department (ED) discharge data from the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project with community-level influenza-like illness activity during each hospital's pandemic period in fall 2009 compared with a corresponding calendar baseline period. We compared inpatient mortality for sentinel conditions at high-surge versus nonsurge hospitals.

RESULTS

US hospitals experienced a doubling of pneumonia and influenza ED visits during fall 2009 compared with prior years, along with an 18% increase in overall ED visits. Although no significant increase in total inpatient admissions occurred overall, approximately 10% of all study hospitals experienced high surge, associated with higher acute myocardial infarction and stroke case fatality rates. These hospitals had similar characteristics to other US hospitals except that they had higher mortality for acute cardiac illnesses before the pandemic. After adjusting for 2008 case fatality rates, the association between high-surge hospitals and increased mortality for acute myocardial infarction and stroke patients persisted.

CONCLUSIONS

The fall 2009 pandemic period substantially impacted US hospitals, mostly through increased ED visits. For a small proportion of hospitals that experienced a high surge in inpatient admissions, increased mortality from selected clinical conditions was associated with both prepandemic outcomes and surge, highlighting the linkage between daily hospital operations and disaster preparedness.
