Assessing COVID-19 Vaccine Hesitancy and Trust in Home Health Workers in New York City: A Pilot Study

OBJECTIVE

This study aimed to identify characteristics surrounding COVID-19 vaccine hesitancy and trust in home health workers (HHWs) in New York City.

METHODS

Data were collected from HHWs through focus group sessions conducted via Zoom. We developed a facilitator guide using the 5C Scale, a validated psychometric tool for assessing vaccine hesitancy. We performed qualitative thematic analysis using a combined inductive and deductive approach.

RESULTS

Major themes that emerged included the following: conflicting information decreased vaccine confidence; individualized outreach is valued when information gathering; mandates and financial incentives may increase skepticism; low health literacy and conflict in personal relationships are barriers to acceptance; and experiencing a severe infection and fear of exposure at work increase acceptance.

CONCLUSIONS

Based on our study, personalized yet consistent messaging may be key to reaching hesitant HHWs.

Like Frying Multiple Eggs in One Pan: a Qualitative Study Exploring the Understanding of Inter-speciality Training in Cancer Care

H igh-quality cancer care is a key priority worldwide. Caring for people affected by cancer requires a range of specific knowledge, skills and experience to deliver the complex care regimens both within the hospital and within the community environment. In June 2022, the European Cancer Organisation along with 33 European cancer societies began working together to develop a curriculum for inter-speciality training for healthcare professionals across Europe. As part of the project, this research consisted of a qualitative survey distributed to the European Union societies via email. The aim of this paper is to disseminate the qualitative findings from healthcare professionals across Europe. Questionnaires were sent out to a convenience sample of 219 healthcare professionals and patient advocates with a response rate of 55% (n = 115). The findings identified that there were four key themes: 'What is inter-speciality training?', 'Barriers and challenges', 'Support throughout the cancer journey' and 'New ways of working'. These results are part of a larger needs analysis and scoping review to inform the development of a core competency framework which will be part of an inter-speciality curriculum for specialist cancer doctors, nurses and other healthcare professionals across Europe. Healthcare professionals will be able to access education and training through the virtual learning environment and workshops and by clinical rotations to other specialties.

Human papillomavirus vaccination at the first opportunity: An overview

The Advisory Committee on Immunization Practices (ACIP) has recommended human papillomavirus (HPV) vaccination for adolescents in the United States since 2006. Though recommended at a similar time to the routine recommendations for adolescent tetanus, diphtheria, and acellular pertussis vaccination (Tdap) and quadrivalent meningococcal vaccination (MCV4), HPV vaccine uptake has consistently lagged behind these other adolescent vaccines. The ACIP recommends HPV vaccination at 11-12 y, with vaccination starting at 9 y of age included as an option that is routinely encouraged by the American Academy of Pediatrics and American Cancer Society. To support efforts to increase HPV vaccination at the first opportunity, this commentary summarizes the current HPV vaccination recommendations and available evidence regarding HPV vaccination starting at 9 y - including recent studies and trials documenting the effectiveness of HPV vaccination at 9 in supporting vaccine series completion, while providing future directions for research and implementation to improve HPV vaccination.

Anticipating & assessing adverse consequences of public health interventions - CONSEQUENT framework

Introduction

Despite the best intentions, public health (PH) interventions can have adverse and other unintended consequences (AUCs). AUCs may arise in novel PH interventions, as well as from known and tested PH interventions implemented in a new context. Despite their importance, this topic has been largely overlooked. Therefore, we used a structured value-guided as well as evidence-based approach, to develop a framework to support researchers, practitioners, and policy-makers in anticipating and assessing AUCs of PH interventions.

Methods

We employed the ‘best-fit’ synthesis approach starting with an a priori framework and iteratively revising this based on systematically identified evidence. The a priori framework was derived from both the WHO-INTEGRATE framework and the Behaviour Change Wheel, to root the framework in global health norms and values, established mechanisms of PH interventions, and a complexity perspective. The a priori framework was advanced based on theoretical and conceptual publications and systematic reviews on the topic of AUCs in PH. Thematic analysis was used to revise the framework and identify new themes. To validate the framework, it was coded against four selected systematic reviews of AUCs of PH interventions.

Results

The CONSEQUENT framework includes two components: the first focuses on AUCs and serves to categorise them; the second component highlights the mechanisms through which AUCs may arise. The first component comprises eight domains of consequences - health-related, health system, human and fundamental rights, acceptability- and adherence-related, equality- and equity-related, social and institutional, economic and resource-related, and environmental.

Conclusions

Both over- and underestimation of AUCs of PH intervention poses risks. The CONSEQUENT framework may facilitate classification and conceptualization of AUCs of PH interventions during their development or evaluation to support evidence-informed decision-making.

Disparities in Marijuana and Tobacco Smoke Incursions Among New York City Families During Early Months of the COVID-19 Pandemic

OBJECTIVES

Once the COVID-19 pandemic arrived in New York City (NYC), stay-at-home orders led to more time spent indoors, potentially increasing exposure to secondhand marijuana and tobacco smoke via incursions from common areas or neighbors. The objective of this study was to characterize housing-based disparities in marijuana and tobacco incursions in NYC housing during the pandemic.

DESIGN

We surveyed a random sample of families from May to July 2020 and collected sociodemographic data, housing characteristics, and the presence, frequency, and pandemic-related change in incursions.

SETTING

Five pediatric practices affiliated with a large NYC health care system.

PARTICIPANTS

In total, 230 caregivers of children attending the practices.

MAIN OUTCOME MEASURES

Prevalence and change in tobacco and marijuana smoke incursions.

RESULTS

Tobacco and marijuana smoke incursions were reported by 22.9% and 30.7%, respectively. Twenty-two percent of families received financial housing support (public housing, Section-8). Compared with families in private housing, families with financial housing support had 3.8 times the odds of tobacco incursions (95% CI, 1.4-10.1) and 3.7 times the odds of worsening incursions during pandemic (95% CI, 1.1-12.5). Families with financially supported housing had 6.9 times the odds of marijuana incursions (95% CI, 2.4-19.5) and 5 times the odds of worsening incursions during pandemic (95% CI, 1.9-12.8). Children in financially supported housing spent more time inside the home during pandemic (median 24 hours vs 21.6 hours, P = .02) and were more likely to have asthma (37% vs 12.9%, P = .001) than children in private housing.

CONCLUSIONS

Incursions were higher among families with financially supported housing. Better enforcement of existing regulations (eg, Smoke-Free Public Housing Rule) and implementation of additional policies to limit secondhand tobacco and marijuana exposure in children are needed. Such actions should prioritize equitable access to cessation and mental health services and consider structural systems leading to poverty and health disparities.

Factors associated with COVID-19 vaccine receipt at two integrated healthcare systems in New York City: a cross-sectional study of healthcare workers

OBJECTIVES

To examine the factors associated with COVID-19 vaccine receipt among healthcare workers and the role of vaccine confidence in decisions to vaccinate, and to better understand concerns related to COVID-19 vaccination.

DESIGN

Cross-sectional anonymous survey among front-line, support service and administrative healthcare workers.

SETTING

Two large integrated healthcare systems (one private and one public) in New York City during the initial roll-out of the COVID-19 vaccine.

PARTICIPANTS

1933 healthcare workers, including nurses, physicians, allied health professionals, environmental services staff, researchers and administrative staff.

PRIMARY OUTCOME MEASURES

The primary outcome was COVID-19 vaccine receipt during the initial roll-out of the vaccine among healthcare workers.

RESULTS

Among 1933 healthcare workers who had been offered the vaccine, 81% had received the vaccine at the time of the survey. Receipt was lower among black (58%; OR: 0.14, 95% CI 0.1 to 0.2) compared with white (91%) healthcare workers, and higher among non-Hispanic (84%) compared with Hispanic (69%; OR: 2.37, 95% CI 1.8 to 3.1) healthcare workers. Among healthcare workers with concerns about COVID-19 vaccine safety, 65% received the vaccine. Among healthcare workers who agreed with the statement that the vaccine is important to protect family members, 86% were vaccinated. Of those who disagreed, 25% received the vaccine (p<0.001). In a multivariable analysis, concern about being experimented on (OR: 0.44, 95% CI 0.31 to 0.6), concern about COVID-19 vaccine safety (OR: 0.39, 95% CI 0.28 to 0.55), lack of influenza vaccine receipt (OR: 0.28, 95% CI 0.18 to 0.44), disagreeing that COVID-19 vaccination is important to protect others (OR: 0.37, 95% CI 0.27 to 0.52) and black race (OR: 0.38, 95% CI 0.24 to 0.59) were independently associated with COVID-19 vaccine non-receipt. Over 70% of all healthcare workers responded that they had been approached for vaccine advice multiple times by family, community members and patients.

CONCLUSIONS

Our data demonstrated high overall receipt among healthcare workers. Even among healthcare workers with concerns about COVID-19 vaccine safety, side effects or being experimented on, over 50% received the vaccine. Attitudes around the importance of COVID-19 vaccination to protect others played a large role in healthcare workers' decisions to vaccinate. We observed striking inequities in COVID-19 vaccine receipt, particularly affecting black and Hispanic workers. Further research is urgently needed to address issues related to vaccine equity and uptake in the context of systemic racism and barriers to care. This is particularly important given the influence healthcare workers have in vaccine decision-making conversations in their communities.

Factors Associated with SARS-CoV-2 Infection in Physician Trainees in New York City during the First COVID-19 Wave

Occupational and non-occupational risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported in healthcare workers (HCWs), but studies evaluating risk factors for infection among physician trainees are lacking. We aimed to identify sociodemographic, occupational, and community risk factors among physician trainees during the first wave of coronavirus disease 2019 (COVID-19) in New York City. In this retrospective study of 328 trainees at the Mount Sinai Health System in New York City, we administered a survey to assess risk factors for SARS-CoV-2 infection between 1 February and 30 June 2020. SARS-CoV-2 infection was determined by self-reported and laboratory-confirmed IgG antibody and reverse transcriptase-polymerase chain reaction test results. We used Bayesian generalized linear mixed effect regression to examine associations between hypothesized risk factors and infection odds. The cumulative incidence of infection was 20.1%. Assignment to medical-surgical units (OR, 2.51; 95% CI, 1.18-5.34), and training in emergency medicine, critical care, and anesthesiology (OR, 2.93; 95% CI, 1.24-6.92) were independently associated with infection. Caring for unfamiliar patient populations was protective (OR, 0.16; 95% CI, 0.03-0.73). Community factors were not statistically significantly associated with infection after adjustment for occupational factors. Our findings may inform tailored infection prevention strategies for physician trainees responding to the COVID-19 pandemic.

More harm than good? Building a framework to identify adverse effects of public health interventions

Background

While the importance of adverse events of medical interventions is widely recognized, adverse effects of public health interventions remain a neglected topic. This project aims to develop a framework to guide researchers and decision-makers to systematically reflect on and identify potential adverse effects of public health interventions.

Methods

We conducted a mixed-method systematic review of theoretical and conceptual publications on adverse events of public health interventions to develop a preliminary framework employing best-fit framework synthesis. We used the WHO-INTEGRATE framework as a starting point for the synthesis, a multidimensional evidence-to-decision framework developed for complex interventions in complex systems.

Results

The framework includes two interlinked parts: The first maps domains in which potential adverse events might arise. Drawing on the WHO-INTEGRATE framework, these domains include aspects related to health, but also domains related to societal, economic, and environmental implications. The second part maps general mechanisms through which public health interventions can lead to adverse effects (e.g. reactive behaviour change, increase of labelling and stigmatization, and exposure to environmental risk-factors).

Conclusions

The framework will be advanced in the second phase of the project through empirical studies of harmful effects in public health interventions, which we will identify through an overview of systematic reviews. Adverse effects of public health interventions are currently not sufficiently considered in research and practice. Taking them into account is essential for informed decision-making and establishing appropriate countermeasures. Our framework could be a valuable asset for researchers and policy makers in developing, implementing and evaluating public health interventions.

Key messages

Awareness of the adverse effects of public health interventions is essential for informed decision-making and establishing countermeasures. This framework supports researchers and decision-makers in systematically reflecting on and identifying adverse events when developing, piloting, implementing or evaluating public health interventions.

US Medical Trainees' Knowledge of Human Papilloma Virus and Head and Neck Cancer

Given the increasing incidence of human papilloma virus (HPV)-positive head and neck cancers (HNCs), discussion of this oncologic outcome should be incorporated into HPV vaccine counseling practices. Yet, preliminary evidence shows that knowledge of the association between HPV and HNC is lacking among most medical trainees. To better characterize this deficit, we nationally assessed knowledge of HPV's association with HNC among medical students and residents across 4 specialties (pediatrics, obstetrics and gynecology, family medicine, and otolaryngology). A total of 3141 responses from 46 states were obtained (n = 402 pediatric residents, n = 346 obstetrics/gynecology residents, n = 260 family medicine residents, n = 87 otolaryngology residents, and n = 2045 medical students). Only 40.3% of surveyed medical students and 56.1% of surveyed obstetrics/gynecology, pediatrics, and family medicine residents identified associations between persistent HPV infection and HNC. When counseling on the vaccine, nonotolaryngology residents more often discussed cervical cancer (99.8%) as compared with HNC (39.7%), commonly because of less HNC knowledge (61.5%). These results suggest that it is imperative to develop educational interventions targeted at medical students and resident trainees on the front line of HPV vaccine counseling and administration.

Improving HPV vaccine delivery at school-based health centers

OBJECTIVE

To identify characteristics associated with human papillomavirus (HPV) vaccination rates, describe barriers and facilitators to vaccine uptake and the potential role for clinician-to-clinician Assessment, Feedback, Incentives, and eXchange (AFIX) visits in school-based health centers (SBHCs). Methods: We conducted clinician-to-clinician AFIX visits at 24 New York City (NYC) high-school and middle-school SBHCs with up-to-date adolescent vaccination rates below 40%. Using NYC's immunization information system, we assessed HPV initiation and series completion rates at the time of AFIX visit and follow-up three to five months later. We analyzed responses to a questionnaire and summarized interviews to identify barriers and facilitators to HPV immunization practices and quality improvement (QI) implementation. Results: Baseline initiation and completion rates were 76% and 43% for high schools, and 81% and 45% for middle schools. SBHCs that allowed adolescent self-consent or did not require separate vaccine consent had higher baseline rates, but was not statistically significant. Barriers to series completion included challenges with scheduling and appointment compliance. At follow-up, high school SBHCs increased HPV vaccine initiation by 2.9 percentage points (p < 0.01) and series completion by 2.7 percentage points (p < 0.05). There was no statistically significant increase at middle school SBHCs. Most SBHCs (88%) chose reminder/recall systems as a QI strategy. Fewer than half (42%) implemented their QI strategy. Conclusions: We identified barriers to HPV vaccine series completion at our sample of SBHCs. Clinician-to-clinician AFIX visits may help improve vaccination rates and encourage providers to address barriers, including streamlining consent processes for HPV vaccination. Abbreviations: School-based health (SBH); quality improvement (QI).

Using Veterans Affairs Medical Center (VAMC) data to identify missed opportunities for HPV vaccination

Despite high HPV prevalence and low vaccination rates in the military, HPV vaccination is not required upon military service initiation. Given that national HPV vaccination rates remain low among people age 19-26 years, military service may represent an opportune time for intervention. The purpose of this study was to quantify the rate of HPV vaccination among young patients entering primary care at a single Veterans Affairs Medical Center (VAMC). Vaccination rates among veterans age ≤ 26 years old at first primary care visit were identified from the institutional data warehouse. Among 1,258 eligible patients, most were male (n = 782). The HPV vaccine initiation rate was 21.2%. Overall, 10.4% of patients received at least 1 HPV vaccine prior to initiating care at the VA (25.2% females and 1.4% males). An additional 10.8% of patients received their first HPV vaccine upon initiating care at the VA. Median age of first HPV vaccination was 21.4 years among patients that initiated the vaccine in the military versus 24.8 years among those that initiated vaccination at the VA. In conclusion, this study demonstrated low HPV vaccination rates both prior to transitioning to VA primary care and once receiving care at the VA. Additionally, among veterans that had not received vaccination upon initiating care at the VA, older age at vaccination was observed. Older age at vaccination may reduce HPV vaccine effectiveness given higher risk of exposure. Addition of HPV to the list of mandated vaccines upon military service initiation should be considered.

Goodpasture disease as a consequence of melioidosis

We describe a case of anti-glomerular basement membrane (GBM) antibody-mediated disease in association with concomitant Burkholderia pseudomallei (melioidosis) bacteraemia. The temporal profile of the illness and initial absence of circulating anti-GBM antibodies, in light of the subsequent definitive histological diagnosis of anti-GBM disease, makes this case interesting and unusual. Additionally, there have been no prior case reports suggesting melioidosis as a cause of biopsy-proven glomerulonephritis.

Single- Versus Multiple-Site Harvesting Techniques for Bone Marrow Concentrate: Evaluation of Aspirate Quality and Pain

BACKGROUND

Bone marrow concentrate (BMC) is growing in popularity as an alternative treatment option in orthopaedics. The regenerative capacity of BMC has been linked to the number of mesenchymal stem cells (MSCs) present in the graft at the time of its clinical application. MSC counts in bone marrow aspirate (BMA) are affected by harvest technique, but controversy exists over which aspiration method optimizes cellular yield while taking patient comfort and risk into consideration.

PURPOSE

To compare a single- versus multiple-site bone marrow aspiration technique to determine which would generate a sufficient volume of high-quality BMA for concentration into a BMC graft. The level of pain experienced by the patient was monitored, since patient comfort should be included in the determination of a safe and effective aspiration technique.

STUDY DESIGN

Controlled laboratory study and cohort study; Level of evidence, 2.

METHODS

BMC samples from 6 patients were sent to an outside source for laboratory analysis. All 6 participants underwent bilateral bone marrow aspiration. Each patient received both techniques at the posterior iliac crest: one side underwent a multiple-site aspiration technique, and the contralateral side underwent a single-site technique with needle redirection. BMA and BMC samples were analyzed for concentrations white blood cells, total nucleated cells, red blood cells, neutrophils, and hematopoietic stem cells. One BMC sample was cultured, and MSC analysis was performed via flow cytometry. All patients underwent monitoring of pain scores during and after the procedure through a visual analog pain scale at 24 hours, 72 hours, and 7 days after BMA.

RESULTS

No significant difference was found between the cell ratios of the single- and multiple-site groups. Both aspiration techniques were found to provide ample colony-forming units without a marked difference in appearance. Additionally, no significant difference was found between groups with regard to MSC numbers. Pain during and 24 hours after the procedure was significantly greater with the multiple-site method than the single-insertion method.

CONCLUSION

The single-insertion method produced final cellular concentrations and culture results that were not significantly different from those of a multiple-insertion method. Additionally, the single-insertion site technique was significantly less painful to the patient at the time of the procedure as well as 24 hours after aspiration.

CLINICAL RELEVANCE

The results of this study indicated that a high-quality bone marrow aspirate is possible with a single-stick aspiration method.

HPV vaccination: Population approaches for improving rates

OBJECTIVE

To review the literature on interventions to increase HPV vaccinations and assess whether The Community Preventive Services Task Force recommendations are supported by current evidence.

METHODS

We used a PubMed search to identify studies that assessed interventions that looked at provider assessment and feedback, provider reminders, client reminder and recall, and clinic based education programs.

RESULTS

Of the 13 studies identified, 8 included client reminder and recall interventions, 4 included provider assessment and feedback and/or provider reminders and 2 included clinic based education. 11 of the 13 studies demonstrated a positive effect on HPV vaccine initiation or completion. Provider assessment and feedback studies were more likely to report a positive effect on HPV vaccine initiation than on series completion, while client reminder recall interventions more frequently produced an effect on series completion than on initiation.

CONCLUSIONS

There is evidence to support the application of the Community Preventive Services Task Force recommendations specifically to HPV vaccination both for client reminder and recall programs and for provider assessment and feedback interventions. Multiple targeted approaches will be needed to substantially impact HPV vaccine rates.

Design challenges for electronic medication administration record systems in residential aged care facilities: a formative evaluation

INTRODUCTION

Electronic medication administration record (eMAR) systems are promoted as a potential intervention to enhance medication safety in residential aged care facilities (RACFs). The purpose of this study was to conduct an in-practice evaluation of an eMAR being piloted in one Australian RACF before its roll out, and to provide recommendations for system improvements.

METHODS

A multidisciplinary team conducted direct observations of workflow (n=34 hours) in the RACF site and the community pharmacy. Semi-structured interviews (n=5) with RACF staff and the community pharmacist were conducted to investigate their views of the eMAR system. Data were analysed using a grounded theory approach to identify challenges associated with the design of the eMAR system.

RESULTS

The current eMAR system does not offer an end-to-end solution for medication management. Many steps, including prescribing by doctors and communication with the community pharmacist, are still performed manually using paper charts and fax machines. Five major challenges associated with the design of eMAR system were identified: limited interactivity; inadequate flexibility; problems related to information layout and semantics; the lack of relevant decision support; and system maintenance issues. We suggest recommendations to improve the design of the eMAR system and to optimize existing workflows.

DISCUSSION

Immediate value can be achieved by improving the system interactivity, reducing inconsistencies in data entry design and offering dedicated organisational support to minimise connectivity issues. Longer-term benefits can be achieved by adding decision support features and establishing system interoperability requirements with stakeholder groups (e.g. community pharmacies) prior to system roll out. In-practice evaluations of technologies like eMAR system have great value in identifying design weaknesses which inhibit optimal system use.

Audit and feedback of antibiotic use: utilising electronic prescription data

BACKGROUND

There is now little doubt that improving antimicrobial use is necessary for the containment of resistance.

OBJECTIVE

To determine whether providing individualised feedback to doctors about their recent compliance with the hospital's antibiotic policy improves compliance with the policy.

METHODS

This study was conducted at a teaching hospital in Sydney, Australia. Computerised alerts integrated into the electronic prescribing system (ePS) inform prescribers of the local antibiotic policy. We utilised prescribing data extracted from the ePS for 'audit and feedback'. Thirty-six prescribers were sent feedback letters via email. We also interviewed doctors who had received letters to explore their views of the feedback and the policy in general.

RESULTS

There was no significant change in compliance with the policy following implementation of the feedback intervention (0% compliant vs 11.9%; p = 0.07). Several problems with the policy and the approval process were identified by researchers during auditing and by prescribers during interviews. Some problems identified made it difficult to accurately assess compliance and for doctors to comply with the policy.

CONCLUSION

Our intervention did not result in improved compliance with the antibiotic policy but revealed practical problems with the policy and approval process that had not been identified prior to the trial. Greater support for the policy by senior doctors and the assignment of more clearly defined roles and responsibilities associated with antibiotic use and approval may result in improved compliance. Harnessing the full potential of technology would streamline the antimicrobial approval process and allow more efficient and reliable monitoring of antibiotic use and compliance. Many of the problems we identified are generic issues of importance to all organisations seeking to integrate antimicrobial stewardship into ePS.

Information literacy of U.S. and Indian engineering undergraduates

To be competitive, contemporary engineers must be capable of both processing and communicating information effectively. Available research suggests that Indian students would be disadvantaged in information literacy in their language of instruction (English) compared to U.S. students because English is not Indian students' native language. Compared to U.S. students, Indian students (a) were predicted to apply practical text processing strategies to a greater extent than analytic strategies and (b) endorse the direct transmission of information over critical, interpretive analysis of information. Two validated scales measuring self-reported use of reading strategies and beliefs about interpreting and critiquing written information were administered to engineering students at an Indian Institute of Technology in their freshman to senior years. Neither prediction was supported: Indian students reported applying analytic strategies over pragmatic strategies and were more disposed to critically analyze information rather than accept it passively. Further, Indian students reported being more analytic and more reflective in their reading behaviors than U.S. engineering students. Additional data indicated that U.S. and Indian students' text-processing strategies and beliefs are associated with the texts that they read and their academic behaviors.

Venous thromboembolic events following foot and ankle surgery in the English National Health Service

Diagnostic and operative codes are routinely collected for every patient admitted to hospital in the English NHS. Data on post-operative complications following foot and ankle surgery have not previously been available in large numbers. Data on symptomatic venous thromboembolism events and mortality within 90 days were extracted for patients undergoing fixation of an ankle fracture, first metatarsal osteotomy, hindfoot fusions and total ankle replacement over a period of 42 months. For ankle fracture surgery (45 949 patients), the rates of deep-vein thrombosis (DVT), pulmonary embolism and mortality were 0.12%, 0.17% and 0.37%, respectively. For first metatarsal osteotomy (33 626 patients), DVT, pulmonary embolism and mortality rates were 0.01%, 0.02% and 0.04%, and for hindfoot fusions (7033 patients) the rates were 0.03%, 0.11% and 0.11%, respectively. The rate of pulmonary embolism in 1633 total ankle replacement patients was 0.06%, and there were no recorded DVTs and no deaths. Statistical analysis could only identify risk factors for venous thromboembolic events of increasing age and multiple comorbidities following fracture surgery.

Venous thromboembolism following foot and ankle surgery is extremely rare, but this subset of fracture patients is at a higher risk. However, there is no evidence that thromboprophylaxis reduces this risk, and these national data suggest that prophylaxis is not required in most of these patients.

Improving the use of venous thromboembolism prophylaxis in an Australian teaching hospital

INTRODUCTION

Hospital-acquired venous thromboembolism (VTE) is a potentially fatal complication of hospitalisation, with meta-analyses and guidelines supporting the use of proven prophylactic measures (graduated compression stockings (GCS) and anticoagulants). Despite this, prophylaxis is underutilised and represents one of the largest gaps between evidence and current clinical practice.

METHODS

All episodes of VTE complicating hospitalisation were ascertained prospectively as part of a quality improvement programme over 3.5 years with a view to designing interventions to improve the use of prophylaxis and reduce the rate of VTE. Interventions initially centred upon highlighting the burden of VTE, the extent of failure to apply guideline evidence into practice, and the development and application of a hospital-wide risk assessment tool. Later interventions sought to build the risk-assessment tool into routine clinical care and enhanced feedback on VTE to clinical teams.

RESULTS

The annual rate of VTE fell in all the years following the intervention (2001), from 2.57 per 1000 cost-weighted separations to a nadir of 1.87 in 2003, with the difference being statistically significant (RR 0.68, 0.47 to 0.99, p = 0.04). The proportion of patients receiving anticoagulant prophylaxis increased (48% to 74%, p = 0.01) but there was no change in the measured use of GCS. There was a marked increase in the use of risk assessment for VTE in the ward setting (7.7% to 100%, p<0.001) during the programme.

CONCLUSION

Affordable and accessible interventions can improve the application of VTE prophylaxis guidelines into daily hospital care and are associated with reductions in this potentially life-threatening complication.

A phase I study of capecitabine, oxaliplatin (CapOx), and lapatinib (L) in metastatic or advanced solid tumors

2579

Background: CapOx is a standard treatment for patients (pts) with metastatic colorectal cancer (mCRC) and has been shown to be equivalent to FOLFOX in a phase III study. L is a tyrosine kinase inhibitor with targeting of the EGF and Her-2 receptors. Preclinical data suggest there may be synergy between L and Cap as well as L and Ox. This phase I study was designed to determine the maximum tolerated dose (MTD) of CapOx and L. Methods: Pts eligible for treatment included those with advanced or metastatic cancers, ECOG PS 2 or less, adequate renal and liver function, and ≤ 3 prior chemotherapy regimens. Treatment over a 21-day cycle was as follows: Ox, single IV infusion on Day 1; Cap, twice-daily oral administration on Days 1 through 14; L, continuous once-daily oral administration. Pts were treated with escalating doses of L (starting at 1000 mg daily) and Cap (starting at 1500 mg/m2/day), while Ox was kept at 130 mg/m2. The primary endpoint was determination of MTD. Results: Ten pts (9/10 female, median age 62 yrs.) were enrolled. One pt had breast cancer and the remainder had non- colorectal GI malignancies (esophagus, hepatobiliary, and pancreas). One pt at dose level 0 experienced dose-limiting toxicity (DLT) (dehydration, elevated bilirubin, hypokalemia). Two pts at dose level 1 (L 1000, Ox 130, Cap 2000) had DLTs of hypokalemia and diarrhea. At an intermediate dose level of L 1000, Cap 1700, Ox 130, two pts experienced DLTs (grade 2 fatigue/anorexia, grade 3 fatigue and dizziness). The MTD was determined to be L 1000 mg daily, Cap 1500 mg/m2/day, Ox 130 mg/m2. There were no treatment-related grade 4 toxicities. The most common grade 3 toxicity was diarrhea (4 pts). There were no grade 3 neuropathies, hematologic toxicities, or rash, and only one case of grade 3 fatigue. One pt with pancreatic cancer had a confirmed partial response (PR) to treatment, and 3 others had stable disease for > 90 days. Conclusions: The regimen of CapOx and L has efficacy in the treatment of solid tumors with established responsiveness to fluoropyrimidines or Ox. The MTD was L 1000 mg daily, Ox 130 mg/m2, and Cap 1500 mg/m2/day. This regimen will be investigated further in a Phase II study involving pts with mCRC.
