313 STREAMLINING A ZOLEDRONIC ACID SERVICE TO A LEVEL TWO HOSPITAL

Background

Approximately, 350-400 patients are admitted to a level 4 hospital for hip-fractures yearly (2019). According to the Irish Hip Fracture Database (2020) the average age for a hip-fracture is 81 years old. Patients post-hip fractures are commenced on Zoledronic acid; a bisphosphonate which is given intravenously 10 days post-surgery and then annually in year two and three. Zoledronic acid is a first line choice of bisphosphonate for the ≥65 population with a fragility fracture.

Methods

274 patients were transferred from the level 4 Hospital waiting list to a level 2 hospital waiting list to streamline the service. Meetings occurred to establish a pathway for the transition of services. A rapid improvement of the level 2 Day Hospital (DH) was commenced. Essential resources, training and information leaflets were developed in order to begin the service. A policy review, procedure guidelines and referral pathway were implemented. An excel database of patient information was transferred between organisations. The 274 patients were triaged by the DH. Pre-assessment phone calls were conducted determining if patients were still eligible for Zoledronic acid.

Results

Of the 274 referrals; 24 had died; 30 refused; 37 were on other bone treatments and another 7 patients haven’t made creatinine clearance, leaving 176. All 176 patients were allocated an appointment for 2022. Of the 176 patients; currently 57 patients have received their Zoledronic acid infusion in the DH. 69 of these referrals had an indicative date for their next Zoledronic acid infusion for dates after April 2022. There are 50 patients yet to receive their treatment which is overdue.

Conclusion

With the prospect of service demands increasing due to Irelands aging population inevitably placing extra pressures on infusion suites in a level 4 hospital. The level 2 hospital has effectively managed to focus on tackling the backlog, streamlining referrals to the bone health service and thus reducing the risk of subsequent hip fractures.

Strategies for developing preparedness and building legacy – learning from the experience of building Health System Resilience in Ireland

Health system resilience to shocks is perhaps the biggest global challenge facing health systems in the 21st Century. Health systems face an increasing prevalence and likelihood of a broad range of shocks (including economic crises, pandemics, climate-related events, political upheavals, mass migration, conflicts and cyberterrorism) that can each undermine the ability of a health system to function well. In particular, the twin processes of dealing with the legacy of a health system shock and preparing for the next shock are distinct but related challenges that face policy makers today. In this presentation the authors will present key findings on improving preparedness and building a constructive legacy drawing from:

• the results of a recent systematic review on how health system resilience has been measured in high income countries over the last twenty years;

• the results of a recent realist review exploring the legacy of the economic crisis for the resilience of the response of the health system to COVID-19, and

• analysis of interviews with Irish policy makers, managers and analysts as they reflect on the different shocks encountered by the Irish system over the last fourteen years.

Triangulating these findings, the authors will reflect on the merits and challenges of measuring resilience and what the focus should be moving forward. Key strategies and approaches will be outlined to best prepare a system for a shock and to leave a positive legacy for the future.

Application of a decision analytic framework for adoption of clinical trial results: are the data regarding TARGIT-A IORT ready for prime time?

The results from randomized clinical trials are often adopted slowly. This practice potentially prevents many people from benefiting from more effective care. Provide a framework for analyzing clinical trial results to determine whether and when early adoption of novel interventions is appropriate. The framework includes the evaluation of three components: confidence in trial results, impact of early, and late adoption if trial results are reversed or sustained. The adverse impact of early adoption, and the opportunity cost of late adoption are determined using Markov modeling to simulate the impact of early and late adoption in terms of quality of life years and resources gained or lost. We applied the framework to the TARGIT-A randomized clinical trial comparing intraoperative radiation (IORT) to standard external beam radiation (EBRT) and considered these results in the context of trials comparing endocrine therapy with and without radiation therapy in postmenopausal women. Confidence in the TARGIT-A trial 4 year results is high because the peak hazard for local recurrence in the trial is between 2 and 3 years. This is consistent with most trials, and no second peak has been observed in similar patient populations, suggesting that the TARGIT-A trial results are stable. The interventions offer approximately equivalent life expectancy. If IORT local recurrences rate were as high as 10 % at 10 years (which is higher than expected), we would project only 0.002 fewer expected life years (less than 1 day) compared to EBRT if IORT is adopted early. However, there is a $1.7 billion opportunity cost of waiting an additional 5 years to adopt IORT in low risk, hormone-receptor-positive, postmenopausal women. EBRT costs an additional $1467 in indirect costs per patient. Applying an evaluative framework for the adoption of clinical trial results to the TARGIT-A IORT therapy trial results in the assessment that the trial results are stable, early adoption would lead to minimal adverse impact, and substantially less resource use. Both IORT and no radiation are reasonable strategies to adopt.

An investigation of the subtype diversity of clinical isolates of Irish Clostridium difficile ribotypes 027 and 078 by repetitive-extragenic palindromic PCR

A repetitive-extragenic palindromic PCR (rep-PCR) subtyping method (DiversiLab) in conjunction with ribotyping, toxinotyping and antimicrobial-susceptibility testing was used to detect subtypes within Clostridium difficile ribotypes 027 and 078. Clinical isolates of ribotypes 027 (toxinotype III) (n = 30) and 078 (toxinotype V) (n = 23) were provided by health-care facilities across the Republic of Ireland over 2 months in 2006 and 1 month in 2009. Ribotype 027 isolates were significantly more related to each other (9 different subtype profiles) when compared to ribotype 078 isolates (14 different profiles) (P = 0.001; cut-off >90 % similarity). Almost half of ribotype 078 isolates (45.5 %) showed no relationship to each other. The clonality of ribotype 027 isolates suggests effective adaptation to the human niche, whereas the considerable genetic diversity within ribotype 078 isolates suggests that they may have originated from a variety of sources. Subtyping correlated well with antimicrobial susceptibility, in particular clindamycin susceptibility for ribotype 027, but diverse antimicrobial-susceptibility profiles were seen in ribotype 078 isolates, even within a single health-care facility. Between 2006 and 2009, a change in the predominant subtype of ribotype 027 was seen, with the recent clone representing half of all ribotype 027 isolates studied. This strain exhibited 89 % similarity to a rep-PCR profile of the North American NAP-1 strain.

A change from the top. One system self-manages its reorganization project

Changes in healthcare arising from economic, legislative, social, and medical pressures will place greater demands on senior managers' future decision making. To maintain its position as a healthcare leader during these volatile times, the Sisters of Charity of the Incarnate Word Health Care System (SCH), Houston, embarked on a self-managed reorganization project in January 1989. The system's senior management team (SMT) established guiding principles that served as the basis for its goals and objectives. A mission statement helped keep the team focused on its goals. A revised SCH Strategic Direction served as the foundation for change. After analyzing the corporate office organizational chart in light of the new strategic direction, the SMT began a reorganization process. This involved the redefinition of many roles, elimination of some positions, and relocation of some functions. Staff attended workshops to adjust to the reorganization. At the workshops employees were given the opportunity to ask questions and participate in the organization's reshaping. The new collaborative management style has been in place two years. As staff develop more supportive cross-functional teams and specialized committees, they are able to tap deeper into their extensive creative resources and collaborate on a vision for SCH.

Heparin kinetics in vascular surgery

Currently there is little information available about the efficacy of heparin during vascular surgery or of the effects of surgical trauma on heparin kinetics. This study was undertaken to evaluate the kinetics of heparin therapy during vascular surgery. Nine patients undergoing major vascular surgery (one carotid, one common iliac and seven aortic operations) were studied both preoperatively and intra-operatively, each patient acting as his own control. Following determination of control activated partial thromboplastin time (APTT) and plasma heparin levels, heparin (100 u/kg body weight) was administered intravenously. Heparin dosage ranged form 4500 units to 8600 units with a mean dose of 6500 units. Plasma heparin and APTT levels were then measured at 10 minute intervals for 1 hour and 20 minute intervals for a second hour. The mean pre-operative and intra-operative APTT levels at ten minutes attained maximal values of 6.6 +/- 3.7 and 8.8 +/- 1.7 times the control respectively. At the end of 2 hours the mean APTT remained greater than 2.5 times the control in both groups. Mean plasma heparin level was 0.83 +/- 0.04 units at 10 minutes and was almost identical in both groups. Heparin level was not a reliable indicator of anticoagulant effect as most patients achieved the same levels but had markedly differing APTT results. The results of this study suggest that excessive doses of heparin may be used in vascular surgery and that surgical trauma does not significantly alter sensitivity to heparin.(ABSTRACT TRUNCATED AT 250 WORDS)

The acute geriatric psychiatry service: a suggested model

In general hospitals, especially on acute medical-surgical, and general psychiatric units, geriatric patients are often exposed to attitudes of resentment or rejection. Individuals with treatable mental illnesses may be relatively neglected or dismissed as "senile," and their special needs not attended to. This tends to occur when the particular psychological issues of elderly patients are not shared by most of the other patients, and also when staff members are prejudiced about old people, either because of fear about their own aging or because of unresolved difficulties with parents or grandparents. The authors believe that age-specific geriatric units are the most effective treatment format for the elderly in need of psychiatric care. One example of such a unit opened in 1980, the Geriatric Psychiatry Unit currently in operation at the Johnston R. Bowman Health Center for the Elderly, a part of Rush-Presbyterian-St. Luke's Medical Center in Chicago, is described.
