Raise the Flag II: sepsis mortality before and after the introduction of a whole-of-system quality improvement programme at a tertiary hospital in New Zealand.

AIMS: To study in-patient mortality before and after the introduction of a whole-of-system sepsis quality improvement programme at a tertiary hospital in New Zealand. METHODS: The "Raise the Flag" sepsis quality improvement programme was launched in 2018. Discharge coding data were used to identify sepsis cases between May 2015 and July 2021. RESULTS: Of 4,268 cases of sepsis identified, 81% were over 55 years old, 34% were of Maori or Pacific Island ethnicity, 61% had significant co-morbid illness and over two thirds (68%) lived in the two highest quintiles of socio-economic deprivation. The adjusted odds of in-patient mortality were lower in the post-launch period (adjusted odds ratio [aOR] 0.83, 95% confidence interval [CI] 0.7-0.98, p<0.05), and were higher in association with age (aOR 1.04 for every additional year of age, 95% CI 1.03-1.05, p<0.01), socio-economic status (aOR 1.47 comparing the highest quintile of socio-economic deprivation with the lowest, 95% CI 1.06-2.04, p=0.02) and comorbidity (aOR 2.42 comparing a comorbidity score of 1 with a score of 0, 95% CI 2.1-3.52, p<0.01). CONCLUSION: In patients with a sepsis diagnosis, the odds of in-patient death were lower following the launch of the Raise the Flag sepsis quality improvement programme.

Raise the Flag I: the impact of a sepsis quality improvement programme on delivery of a sepsis resuscitation bundle at a tertiary hospital in New Zealand.

AIMS: To study changes in sepsis resuscitation practice at a tertiary hospital before and after the introduction of a quality improvement programme, and to identify variables associated with its delivery. METHODS: "Raise the Flag", a quality sepsis programme, including the Sepsis Six, was launched in 2018. Adult patients with sepsis were sampled prior to the intervention and during two subsequent periods. RESULTS: Clinicians were more likely to deliver the resuscitation bundle in the post-implementation period (adjusted odds ratio [aOR] 2.20, 95% confidence interval [CI] 1.27-3.79, p=0.005). This was not sustained at 18-30 months (aOR 1.22, 95% CI 0.89-1.66, p=0.21). After adjusting for potential confounders, each additional decade of patient age was associated with reduced odds of receiving the bundle (aOR 0.83, 95% CI 0.73-0.95, p=0.005). Admission to intensive care increased in the combined post-implementation periods (aOR 2.81, 95% CI 1.13-6.97, p=0.03). CONCLUSION: The odds of receiving a resuscitation bundle improved immediately following the launch of the Raise the Flag programme. Resuscitation practice differed based on patient age. Odds of admission to intensive care were increased.

Counting the cost of major infection and sepsis in New Zealand: an exploratory study using the National Minimum Data Set.

AIM: To explore the population-at-risk and potential cost of a sepsis episode in New Zealand. METHOD: Retrospective analysis of the National Minimum Data Set using two code-based algorithms selecting (i) an inclusive cohort of hospitalised patients diagnosed with a 'major infection' with the potential to cause sepsis and (ii) a restricted subset of these patients with a high likelihood of clinical sepsis based on the presence of both a primary admission diagnosis of infection and at least one sepsis-associated organ failure. RESULTS: In 2016, 24% of all inpatient episodes were associated with diagnosis of a major infection. The sepsis coding algorithm identified a subset of 1,868 discharges. The median (IQR) reimbursement associated with these episodes was $10,381 ($6,093-$10,964). In both groups, 30-day readmission was common (26.7% and 11% respectively). CONCLUSIONS: Infectious diseases with the potential to cause sepsis are common among hospital inpatients. Direct treatment costs are high for those who present with or progress to sepsis due to these infections.

The burden of Legionnaires' disease in New Zealand (LegiNZ): a national surveillance study.

BACKGROUND: Legionnaires' disease is under-diagnosed because of inconsistent use of diagnostic tests and uncertainty about whom to test. We assessed the increase in case detection following large-scale introduction of routine PCR testing of respiratory specimens in New Zealand. METHODS: LegiNZ was a national surveillance study done over 1-year in which active case-finding was used to maximise the identification of cases of Legionnaires' disease in hospitals. Respiratory specimens from patients of any age with pneumonia, who could provide an eligible lower respiratory specimen, admitted to one of 20 participating hospitals, covering a catchment area of 96% of New Zealand's population, were routinely tested for legionella by PCR. Additional cases of Legionnaires' disease in hospital were identified through mandatory notification. FINDINGS: Between May 21, 2015, and May 20, 2016, 5622 eligible specimens from 4862 patients were tested by PCR. From these, 197 cases of Legionnaires' disease were detected. An additional 41 cases were identified from notification data, giving 238 cases requiring hospitalisation. The overall incidence of Legionnaires' disease cases in hospital in the study area was 5·4 per 100 000 people per year, and Legionella longbeachae was the predominant cause, found in 150 (63%) of 238 cases. INTERPRETATION: The rate of notified disease during the study period was three-times the average over the preceding 3 years. Active case-finding through systematic PCR testing better clarified the regional epidemiology of Legionnaires' disease and uncovered an otherwise hidden burden of disease. These data inform local Legionnaires' disease testing strategies, allow targeted antibiotic therapy, and help identify outbreaks and effective prevention strategies. The same approach might have similar benefits if applied elsewhere in the world. FUNDING: Health Research Council of New Zealand.

Evidence of High Mortality and Increasing Burden of Sepsis in a Regional Sample of the New Zealand Population.

BACKGROUND: Sepsis is a life-threatening complication of infection. The incidence of sepsis is thought to be on the increase, but estimates making use of administrative data in the United States may be affected by administrative bias. METHODS: We studied the population-based incidence of sepsis in the Waikato region of New Zealand from 2007 to 2012 using International Classification of Diseases, Tenth Revision, Australian Modification, which lacks a specific code for sepsis. RESULTS: Between 2007 and 2012, 1643 patients met coding criteria for sepsis in our hospitals. Sixty-three percent of patients were 65 or over, 17% of cases were admitted to an intensive care unit, and the in-hospital and 1-year mortality with sepsis was 19% and 38%, respectively. Age-standardized rate ratios (ASRRs) demonstrated that sepsis was associated with male sex (ASRR 1.4; 95% confidence interval [CI], 1.23-1.59), Maori ethnicity (ASRR 3.22 compared with non-Maori; 95% CI, 2.85-3.65), study year (ASRR 1.62 comparing 2012 with 2008; 95% CI, 1.18-2.24), and socioeconomic deprivation (ASRR 1.72 comparing the highest with the lowest quintile of socioeconomic deprivation; 95% CI, 1.5-1.97). Multiorgan failure was present in approximately 20% of cases in all age groups. Intensive care unit admission rate fell from 30% amongst 25- to 34-year-olds to less than 10% amongst those aged 75 and over. CONCLUSIONS: In a 9% sample of the New Zealand population, the incidence of sepsis increased by 62% over a 5-year period. Maori, elderly, and disadvantaged populations were most affected.

Medication discrepancies and associated risk factors identified among elderly patients discharged from a tertiary hospital in Singapore.

INTRODUCTION: Medication discrepancies and poor documentation of medication changes (e.g. lack of justification for medication change) in physician discharge summaries can lead to preventable medication errors and adverse outcomes. This study aimed to identify and characterise discrepancies between preadmission and discharge medication lists, to identify associated risk factors, and in cases of intentional medication discrepancies, to determine the adequacy of the physician discharge summaries in documenting reasons for the changes. METHODS: A retrospective clinical record review of 150 consecutive elderly patients was done to estimate the number of medication discrepancies between preadmission and discharge medication lists. The two lists were compared for discrepancies (addition, omission or duplication of medications, and/or a change in dosage, frequency or formulation of medication). The patients' clinical records and physician discharge summaries were reviewed to determine whether the discrepancies found were intentional or unintentional. Physician discharge summaries were reviewed to determine if the physicians endorsed and documented reasons for all intentional medication changes. RESULTS: A total of 279 medication discrepancies were identified, of which 42 were unintentional medication discrepancies (35 were related to omission/addition of a medication and seven were related to a change in medication dosage/frequency) and 237 were documented intentional discrepancies. Omission of the baseline medication was the most common unintentional discrepancy. No reasons were provided in the physician discharge summaries for 54 (22.8%) of the intentional discrepancies. CONCLUSION: Unintentional medication discrepancies are a common occurrence at hospital discharge. Physician discharge summaries often do not have adequate information on the reasons for medication changes.

Proton pump inhibitors: Are we still prescribing them without valid indications?

BACKGROUND: Evidence from several Western studies has shown an alarmingly high and inappropriate rate of prescription of proton pump inhibitors (PPIs), which may be associated with increased healthcare costs and adverse outcomes. PPI prescribing patterns remain largely unknown in well-developed healthcare systems in Southeast Asia. AIMS: We aimed to determine the prevalence of inappropriate prescription of PPI among elderly patients without documentation of valid indications, in a tertiary teaching hospital in Singapore. METHOD: We carried out a retrospective clinical records review of 150 elderly patients aged ≥65 years that had been admitted to two internal medicine wards between 25 May 2011 and 28 June 2011 to determine the appropriateness of indications for PPIs prescribed at hospital discharge. PPI indications were categorised as "valid", "likely invalid", and "probable" based on current clinical literature. Pre-admission and discharge prescriptions were reviewed to determine continuation of pre-admission and new PPI prescriptions at discharge. Data on clinical characteristics and concurrent use of ulcerogenic medications were collected. RESULTS: From a total of 150 patients, 80 (53 per cent) received prescriptions for PPIs. Of these, 65 (81.2 per cent) had no valid documented indications (i.e., the indication was classed as "likely invalid"); 10 (12.5 per cent) had valid indications; and in five cases (6.2 per cent) the indication was "probable". The most common "likely invalid" indication was primary gastrointestinal bleeding prophylaxis (GIP) among low-dose aspirin users in 28 patients (43 per cent) of invalid PPI prescriptions. CONCLUSION: Inappropriate prescribing of PPIs without documented valid indications was prevalent among elderly patients at our tertiary teaching hospital in Singapore, providing evidence that shows a similar trend to PPI prescribing to data from Western countries.

When traditional model meets competencies in Singapore: beyond conflict resolution.

INTRODUCTION: The implementation of competency-based internal medicine (IM) residency programme that focused on the assurance of a set of 6 Accreditation Council for Graduate Medical Education (ACGME) core competencies in Singapore marked a dramatic departure from the traditional process-based curriculum. The transition ignited debates within the local IM community about the relative merits of the traditional versus competency-based models of medical education, as well as the feasibility of locally implementing a training structure that originated from a very different healthcare landscape. At the same time, it provided a setting for a natural experiment on how a rapid integration of 2 different training models could be achieved. MATERIALS AND METHODS: Our department reconciled the conflicts by systematically examining the existing training structure and critically evaluating the 2 educational models to develop a new training curriculum aligned with institutional mission values, national healthcare priorities and ACGME-International (ACGME-I) requirements. RESULTS: Graduate outcomes were conceptualised as competencies that were grouped into 3 broad areas: personal attributes, interaction with practice environment, and integration. These became the blueprint to guide curricular design and achieve alignment between outcomes, learning activities and assessments. The result was a novel competency-based IM residency programme that retained the strengths of the traditional training model and integrated the competencies with institutional values and the unique local practice environment. CONCLUSION: We had learned from this unique experience that when 2 very different models of medical education clashed, the outcome may not be mere conflict resolution but also effective consolidation and transformation.

Presentation and outcome amongst older Singaporeans living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS): does age alone drive excess mortality?

INTRODUCTION: There is little detailed information on human immunodeficiency virus (HIV) amongst older adults in Singapore. MATERIALS AND METHODS: A retrospective study of 121 consecutive referrals of patients presenting for HIV care was conducted. Demographic, clinical and laboratory variables were collected. A prognostic model derived from the North American Veterans' Affairs Cohort Study (VACS) was used to estimate prognosis. RESULTS: The median age at presentation was 43 (range, 18 to 76). Thirty-eight patients (31%) were aged 50 or older and 106 patients (88%) were male. Older patients were more likely to be of Chinese ethnicity (P = 0.035), married (P = 0.0001), unemployed or retired (P = 0.0001), and to have acquired their infection heterosexually (P = 0.0002). The majority of patients in both groups were symptomatic at presentation. Eighty-one (67%) had CD4 counts less than 200 at baseline with no observable differences in HIV ribonucleic acid (RNA) or clinical stage based on age. Non-Acquired Immunodeficiency Syndrome (AIDS) morbidity was observed more frequently amongst older patients. The estimated prognosis of patients differed significantly based on age. Using the VACS Index and comparing younger patients with those aged 50 and above, mean 5 year mortality estimates were 25% and 50% respectively (P <0.001). A trend towards earlier antiretroviral therapy was noted amongst older patients (P = 0.067) driven mainly by fewer financial difficulties reported as barriers to treatment. CONCLUSION: Older patients form a high proportion of newly diagnosed HIV/AIDS cases and present with more non-AIDS morbidity. This confers a poor prognosis despite comparable findings with younger patients in terms of clinical stage, AIDS-defining illness, CD4 count and HIV viral load.

The successful, rapid transition to a new model of graduate medical education in Singapore.

Graduate medical education (GME) in Singapore recently underwent major reform (2009-2012), leading to accreditation of residency programs by the Accreditation Council for Graduate Medical Education-International (ACGME-I) within two years of the initial commitment to change. The main aims of the reforms were to implement best practices in GME, to provide better support structures for program administration, and to bring all specialty training under one administrative umbrella. The authors outline the historic development of GME in Singapore, the complexities of the model in place immediately prior to ACGME-I accreditation, and the difficulties addressed by the proposed changes, leading to a description of implementation efforts at the National University Hospital of Singapore, a university-affiliated academic medical center. The authors describe the institutional factors uniting hospital leaders in support of reform, the recruitment of a team to manage change within the institution, the inauguration of a new office for GME, and the faculty development initiatives needed to educate faculty leading the change process. The preparation and execution of specific initiatives designed to improve GME and the communication strategies needed to coordinate and publicize change efforts are outlined, as well as strategies for sustaining improvements and building them into the culture of the institution. The authors demonstrate that external accreditation can be a powerful driver of educational reform and summarize key lessons derived from Kotter principles, a current model of change management.

Fusobacterial infections: clinical spectrum and incidence of invasive disease.

OBJECTIVES: Clinically significant infections caused by members of the genus Fusobacterium are rare. We sought to describe the spectrum of clinical disease and epidemiology of these conditions presenting to an acute hospital over a five year period. METHODS: Clinical records relating to consecutive laboratory isolates of Fusobacterium species were reviewed and cases classified according to pre-specified definitions of primary site and invasive infection. RESULTS: 78 Fusobacterium isolates were identified, 25 of which were associated with invasive disease, most commonly in men (76% of cases). Invasive Fusobacterium necrophorum infection of the head and neck was not observed in patients over 50. Invasive intra-abdominal disease was not observed amongst those under 60. 2 cases of Fusobacterium nucleatum bacteraemia were identified in neutropenic children. One retroperitoneal abscess may have represented secondary infection due to periodontitis. Obstetric infections were the most common clinical syndromes associated with isolates from the female genital tract. The incidence of invasive head and neck disease in the population aged 15-50 was 6.7 per million/year. There were no deaths. CONCLUSIONS: Invasive fusobacterial infections are rare, affect distinct patient groups and are associated with good clinical outcomes in the majority of cases.
