RESUMEN

This observational case series in 65 premenopausal women with abnormal uterine bleeding evaluated whether transvaginal ultrasound followed by saline infusion sonohysterography (SIS) prevented unnecessary hysteroscopy. Although SIS indicated that hysteroscopy was unnecessary in eight women, this benefit was offset by the invasive nature of the scan, the number of endometrial abnormalities falsely detected by SIS and the cost of the additional investigation.

RESUMEN

Background and context An increasing number of drugs and blood products need to be delivered by intravenous infusion. In the Canterbury region of New Zealand, these have historically been delivered at a hospital site; however, some infusions could be delivered in a community setting without compromising patient safety. Assessment of problem The Canterbury health system has a key strategic objective of delivering care close to patients' homes. In 2018, Canterbury district health board (DHB) put out a tender for a community infusion service that would deliver blood products and other intravenous drugs with appropriate medical oversight. Strategies for improvement Following an interview and selection process, a fee-for-service contract was developed with a group of general practices with partial common ownership. It was nurse-led with medical oversight available. In July 2018, a Community Infusion Service (CIS) was started in two urban sites in Canterbury. It later expanded to two more sites, one urban and one rural. Results From July 2018 to May 2021, over 3000 infusions and blood transfusions were delivered by the CIS across seven infusion types (blood; immunoglobulin; infliximab; natalizumab; pamidronate; toculizumab; zoledronic acid). Both general practice and hospital services referred patients to the CIS. No major incidents were reported. Patients reported satisfaction with the service. Lessons Infusions and blood products can be delivered safely nearer to patients' homes in primary care in a New Zealand setting. Medical input was rarely required; however, the transition was resource-intensive; it required both overall process and criteria negotiations, as well as individual patient discussions. In its initial stages, the CIS did not have adequate clinical governance and operational support, which affected the speed and scale of its development.

RESUMEN

AIMS: The New Zealand "Standards for Adult Respiratory and Sleep Services" were published by the Ministry of Health in 2004. A 2006 survey demonstrated major gaps in the staffing and service provision and significant variation between district health boards (DHBs). We repeated this survey in 2019/20 in order to highlight issues which should be addressed as part of health service reforms. METHODS: Survey of all adult DHB respiratory services assessing staffing and service provision. RESULTS: There is marked regional variation in staffing levels for all specialist clinicians. There are 1.18 FTE/100,000 population respiratory physicians, which is well below Australian and United Kingdom levels. Two hundred thousand people in New Zealand do not have access to a local respiratory physician. For provided services we found a four-fold variation between DHBs for CPAP treatments, six-fold for oxygen services, and eight-fold for pulmonary rehabilitation. CONCLUSION: The place of residence of New Zealanders determines access to respiratory services. There are inequities in access, with little progress made since 2006. Data on health outcomes are required. The restructure of the health service must rectify this situation. The need to end a "postcode lottery" is demonstrated when reviewing current respiratory services in New Zealand.

RESUMEN

AIM: To describe the establishment of a national prostate cancer clinical quality registry (PCOR-NZ) within the New Zealand healthcare system and discuss the challenges encountered and achievements obtained during its development. Additionally, to provide a descriptive snapshot of the patients enrolled thus far. METHODS: A review of the processes underpinning the start-up and maintenance of the registry was undertaken. We also extracted data from PCOR-NZ in April 2021 to report on patients diagnosed between 2016 and 2019 that had at least 12 months of follow-up. RESULTS: Following ethical approval in 2015, a steering committee made up of clinicians, public health specialists and patient representatives was constituted, and site recruitment commenced. Men aged ≥18 years with a diagnosis of incident prostate cancer from participating sites are eligible for enrolment in PCOR-NZ. The registry functions with an opt-out consent model and captures diagnosis, treatment and short-term outcomes, with a particular focus on quality-of-life measures. As of January 2021, 100% of public hospitals and 36% of private urology clinics in New Zealand are actively participating in the registry. 5,858 men, including 411 who identified as Maori (7.0%), were diagnosed between 2016 and 2019 and enrolled in the registry. Population coverage is currently estimated to be almost 70%. Opt-out is estimated to be 2.8%. CONCLUSIONS: PCOR-NZ is providing quality diagnostic, treatment and outcome data for promoting enhancements in the care of men with prostate cancer. The registry resources are therefore valuable for informing and supporting quality improvement resourcing of this common cancer.

RESUMEN

A nationwide program to promote preparation of advance care plans (AC Plans) was introduced in Canterbury, New Zealand, in 2013. The program was developed by local facilitators who provided support and organised education seminars and an accredited training program for health-care professionals. Information and templates for an AC Plan were available to these professionals and the community on local health-care websites and secure online systems designed to allow plans to be viewed across all health-care sectors. The number of AC Plans prepared has increased steadily, although people in minority ethnic populations or in the most deprived socioeconomic quintile are less likely to have a plan. While nurses have become the predominant group guiding people through the process of preparing an AC Plan, the involvement of staff in residential care homes has remained low. Local audit showed that 82% of people with an AC Plan died in a community setting, frequently their preferred place of death.

RESUMEN

AIM: To evaluate prospectively a clinical pathway for investigation of haematuria that involves an initial screening using a urinary biomarker of bladder cancer (Cxbladder Triage™ (CxbT)) in combination with either a renal ultrasound or a computed tomography imaging. Only test-positive patients are referred for specialist assessment and flexible cystoscopy. METHODS: The clinical outcomes of 884 patients with haematuria who presented to their general practitioner were reviewed. Outcome measurements included the findings of laboratory tests, imaging, cystoscopies, specialist assessment and histology. RESULTS: Forty-eight transitional cell carcinomas (TCC) and three small cell carcinomas were diagnosed in the study cohort. The clinical pathway missed a solitary, small, low-risk TCC. When combined, imaging and CxbT had a sensitivity of 98.1% and a negative predictive value of 99.9% to detect a bladder cancer. Follow-up for a median of 21 months showed no further new cases of bladder cancer had occurred in the patient cohort. Review of all new bladder cancers diagnosed in the 15 months following the study showed that none had been missed by haematuria assessment using the clinical pathway. CONCLUSIONS: The combination of CxbT and imaging reliably identifies patients with haematuria who can be managed safely in primary care without the need for a secondary care referral and a flexible cystoscopy.

RESUMEN

AIM: This retrospective review examined the influence of age and severity of comorbidities on goals-of-care in advance care plans (ACPlans) and concordance between these wishes and care received during hospital admission. METHODS: The medical records of 149 people with an ACPlan admitted to a public hospital were reviewed to evaluate concordance with treatment. The associations between age and comorbidities and goals-of-care were determined using contingency tables and logistic regression analyses. RESULTS: The majority of the review cohort were Caucasian and elderly, with people from minority ethnic groups under-represented compared to census data. Increasing age had a measurable influence on the choice of goal-of-care, whereas comorbidity severity had less influence on this decision. In 60 of the 411 hospital admissions the patient was classified as incompetent, with the goal-of-care adhered to in 59 of these cases and treatment preferences adhered to in six of seven cases. Fifty-five people had died since writing their ACPlan, with 63% dying at their preferred place or with no preference stated. CONCLUSIONS: Age and to a lesser extent the severity of comorbidities influence the choice of goal-of-care in an ACPlan. Our review also showed that end-of-life care appeared to adhere to the instructions in the plan.

RESUMEN

Objectives HealthPathways, pioneered in Canterbury, New Zealand, in 2008, is a web-based tool designed to promote health care integration and patient management in primary care and to reduce fragmentation in the delivery of health services. This cross-sectional study evaluated the utilisation and perceptions of this tool among health professionals in Australia and New Zealand. Methods A cross-sectional survey was administered online through Research Electronic Data Capture (REDCap) to general practitioners (GPs), practice nurses and managers, nurse practitioners, specialist and community nurses, hospital clinicians, nurses, managers, and allied health professionals between April and September 2018. The frequency of HealthPathways use in the previous month was modelled as an ordered response using an ordered logistic regression model after adjusting for the possible effects of sex, age, years in clinical practice, location and time spent in practice. Results Health professionals perceived HealthPathways to be useful in primary care management and referral, as well as in the prereferral treatment of patients. GPs in New Zealand, New South Wales and Victoria were 73%, 47% and 27% more likely to have used HealthPathways ≥10 times in the previous month respectively. Conclusion The results suggest that HealthPathways is having a positive effect on healthcare systems in New Zealand and Australia. However, differences in uptake suggests the need for focused implementation, integration into eReferral software and expanding the tool to medical students, registrars, allied health professionals and potentially patients to encourage behavioural change. What is known about the topic? Early evaluations suggest that HealthPathways is a useful tool for health professionals, although uptake and utilisation may be limited. However, there is no comparative evidence regarding uptake and implementation of the tool. What does the paper add? This study is among the first to provide a comparative narrative of the literature assessing the implementation and uptake of HealthPathways across Australia and New Zealand. It is also among the first to compare the perceptions of allied health professionals in the use of HealthPathways across Australia and New Zealand. What are the implications for practitioners? The results of this study suggest the need for focused implementation, integration into eReferral software and expanding the tool to medical students, registrars, allied health professionals and potentially patients to encourage behavioural change.

RESUMEN

OBJECTIVE: Metabolic abnormalities in patients with bipolar disorder may be secondary to obesity, aspects of the disorder or its treatment. To investigate this further, the purpose the present study was to compare insulin resistance, components of the metabolic syndrome and adiponectin levels in a group of overweight bipolar patients taking sodium valproate and a group of non-psychiatric control subjects. METHODS: Data were collected from 60 overweight bipolar patients who had experienced clinically significant weight gain thought to be related to sodium valproate treatment and from 60 control subjects without psychiatric illness matched for age, gender, body mass index and ethnicity. RESULTS: The frequency of the metabolic syndrome was high in both groups (50% and 32%, respectively), although not significantly different between groups (p = 0.06). Similar frequencies of insulin resistance (HOMA-IR), abdominal obesity, hypertriglyceridaemia, hypertension and fasting hyperglycaemia were found in both groups. High-density lipoprotein cholesterol levels were lower in patients (p = 0.006), while adiponectin was unexpectedly higher than in control subjects (9.6+/-5.9 microg mL(-1) vs 7.4+/-4.3 microg mL(-1), p = 0.03). The frequencies of insulin resistance (HOMA-IR), the metabolic syndrome and its individual components were not significantly different in patients taking atypical antipsychotic medication and patients not on these medications. CONCLUSIONS: Frequencies of insulin resistance and the metabolic syndrome were similar in bipolar patients taking sodium valproate and matched control subjects, but dyslipidaemia was more frequent. Adiponectin levels were higher in patients. Further research is required to clarify the reasons for these findings.

RESUMEN

AIM: To examine prospectively the impact of adding a urinary biomarker of bladder cancer (Cxbladder TriageTM, CxbT) to a clinical pathway for investigating haematuria. METHODS: The clinical outcome of 571 patients with haematuria who presented to their general practitioner was reviewed. Outcome measurements included the findings of laboratory tests, imaging, cystoscopies, histology and specialist assessments. The data were used to model a theoretical clinical pathway that involved initial screening using CxbT in combination with imaging, and only test positive patients being referred for specialist assessment and cystoscopy. RESULTS: All patients underwent cystoscopy and 44 transitional cell carcinomas were diagnosed in the study cohort, with two low-risk cancers missed by CxbT, one of which was also not detected by imaging. When combined, imaging and CxbT had a sensitivity of 97.7% and negative predictive value of 99.8%. CONCLUSIONS: In our series, all significant bladder cancers were diagnosed by imaging and CxbT before cystoscopy was undertaken. The high negative predictive value of this clinical pathway would allow approximately one-third of patients with haematuria to be managed without cystoscopy.

RESUMEN

BACKGROUND: Growth in emergency department (ED) attendance and acute medical admissions has been managed to very low rates for 18 years in Canterbury, New Zealand, using a combination of community and hospital avoidance strategies. This paper describes the specific strategies that supported management of acutely unwell patients in the community as part of a programme to integrate health services. INTERVENTION: Community-based acute care was established by a culture of close collaboration and trust between all sectors of the health system, with general practice closely involved in the design and management of the services, and support provided by hospital specialists, coordination and diagnostic units, and competent informatics. Introduction of the community-based services was aided by a clinical guidance website and an education programme for general practice teams and allied health professionals. OUTCOMES: Attendance at EDs and acute medical admission rates have been held at low growth and, in some cases, shorter lengths of hospital stay. This trend was especially evident in elderly patients and those with ambulatory care sensitive or chronic disorders. CONCLUSIONS: A system of community-based care and education has resulted in sustained gains for the Canterbury health system and freed-up hospital resources. This outcome has engendered a sense of empowerment for general practice teams and their patients.

RESUMEN

We investigated whether the adipocytokine, adiponectin, protected the endothelium against damage induced by oxidised low-density lipoprotein cholesterol (oxLDL). Human umbilical vein endothelial cells were cultured with either 200 or 350 microg/ml oxLDL, with or without adiponectin purified from human serum (12 microg/ml). Cellular oxidative status was assessed by measuring reactive oxygen species (ROS), peroxynitrite and glutathione (GSH) levels, while cell function was evaluated by measuring nitric oxide (NO) levels and immunohistochemical examination of proteins in the adherens cell junction. At a concentration of 200 microg/ml, oxLDL induced a small increase in ROS and peroxynitrite levels, a two-fold increase in GSH levels and no changes in NO levels or localisation of proteins in the adherens junction. However, 350 microg/ml of oxLDL induced a marked increase in ROS and peroxynitrite levels, a four-fold reduction in GSH levels and a significant decrease in NO levels and disruption of the adherens junctions. Addition of adiponectin to the cultures resulted in maintenance of normal ROS, peroxynitrite and GSH levels, with no change in either NO levels or protein localisation in the adherens junction. This study demonstrates that adiponectin protects against endothelial dysfunction and cellular disruption induced by oxLDL, with this effect being due, in part, to maintenance of intracellular GSH levels.

RESUMEN

OBJECTIVES: A programme was introduced in Canterbury, New Zealand to evaluate the diagnosis and treatment of frenulum releases in newborn infants with suspected tongue-tie (ankyloglossia). The primary goals were to support breastfeeding and ensure that unnecessary surgery was avoided. METHODS: Local healthcare professionals reached consensus on a pathway for improving management of infants with tongue-tie and breast-feeding difficulties. This embedded an expert breast-feeding review and assessment of lingual function using a validated method, the Bristol Tongue-tie Assessment Tool (BTAT). Infants with breastfeeding problems related to tongue-tie had a frenotomy at a hospital outpatient clinic. An education programme was developed to support introduction of the new clinical pathway and included seminars and online information for healthcare professionals and the general public. RESULTS: Frenotomy intervention rate reduced markedly from 11.3% in 2015 to 3.5% by mid-2017. Feeding methods were not different before or after surgery between infants who received a frenotomy and those who did not. Initially, the BTAT threshold for frenotomy was set at ≤5, however the final clinical pathway combined a breastfeeding assessment and a BTAT threshold of ≤4. The education programs assisted with the changes in practice, while increased use of the clinician guidance and public health information websites confirmed growing awareness of tongue-tie and community breastfeeding support. CONCLUSIONS: Establishing consistent multidisciplinary assessment of tongue-tie in infants with feeding difficulties led to a marked reduction in frenotomy intervention rate. 23% of the frenotomy group in the 2016 audit showed a significant improvement in the ability to breastfeed, but overall there was no difference in the feeding pattern of infants who either received or were declined a frenotomy. The development of a supportive education programme and availability of online information about tongue-tie for health professionals and consumers contributed to successful uptake of the new clinical pathway.

RESUMEN

The devastating 2011 earthquake in Christchurch destroyed or badly damaged healthcare infrastructure, including Christchurch Hospital. This forced change in management of exacerbations of chronic obstructive pulmonary disease (COPD), which until that point had frequently led to admission to hospital and focused attention on providing safe community options for care. This paper describes the process of understanding factors contributing to high admission frequency with exacerbations of COPD and also describes a process of change, predominantly to healthcare delivery systems and philosophies, and the subsequent outcomes. What became clear in understanding admissions with COPD to Christchurch Hospital was that the behaviour of the patient, in the context of exacerbations, and the subsequent response of the system to the patient, led to admission being the default option, in spite of low severity of the exacerbation itself. By altering systems' responses to exacerbations, with a linked care process between ambulances, community care and hospitals, we were able to safely reduce admissions for COPD, with a sustained overall reduction in bed-day occupancy for COPD of ~48%. We would encourage these discussions and changes to occur without the stimulus of an earthquake in your healthcare environment!

RESUMEN

OBJECTIVES: Plasma retinol-binding protein (RBP) has been linked to insulin resistance and cardiovascular risk, yet little is know of its natural variation in plasma. We examined this in normal subjects and compared plasma levels and variability in lean subjects and subjects with the metabolic syndrome. METHODS: We established an "in house" ELISA for plasma RBP and measured levels in 20 normal subjects over daylight hours and 2 subject groups, either lean or classified with the metabolic syndrome. RESULTS: Plasma RBP in normal subjects did not vary over the day with no differences between males and females. There was also no difference in plasma RBP levels and between the age- and sex-matched lean subjects compared to the metabolic syndrome group. CONCLUSION: The lack of variation in plasma RBP in normal subjects and the lack of difference between plasma RBP in normal and metabolic syndrome subjects suggest the link between plasma RBP and insulin resistance is tenuous. Investigating a large cohort over the diabetic non-diabetic spectrum may clarify this issue.

RESUMEN

INTRODUCTION Unmet needs are a key indicator of the success of a health system. Clinicians and funders in Christchurch, Canterbury, New Zealand were concerned that unmet health need was hidden. AIM The aim of this survey was to estimate the proportion of patients attending general practice who were unable to access clinically indicated referred services. METHODS The survey used a novel method to estimate unserviced health needs. General practitioners (GPs, n = 54) asked their patients (n = 2135) during a consultation about any health needs requiring a referred service. If both agreed that a service was potentially beneficial and not available, this was documented on an e-referral system for review. The outcomes of actual referrals were also reviewed. RESULTS The patient group was broadly representative of the Canterbury population, but over-sampled female and middle-aged people and under-sampled Maori. Data adjusted to regional demographics showed that 3.6% of patients had a GP-confirmed unserviced health need. Elective orthopaedic surgery, general surgery and mental health were areas of greatest need. Unserviced health needs were significantly (P ≤ 0.05) associated with greater deprivation, middle-age, and receiving high health-use subsidies. DISCUSSION To our knowledge, this is the first survey of GP and patient agreement on unserviced referred health needs. Measuring unserviced health needs in this way is directly relevant to service planning because the gaps identified reflect clinically indicated services that patients want and need. The survey method is an improvement on declined referral rates as a measure of need. Key factors in the method were using a patient-initiated GP consultation and an e-referral system to collect data.

RESUMEN

Prior to 2007, increasing demand for sleep services, plus inability to adequately triage severity, led to long delays in sleep assessment and accessing continuous positive airway pressure. We established a community sleep assessment service carried out by trained general practices using a standardised tool and overnight oximetry. All cases were discussed at a multi-disciplinary meeting, with four outcomes: severe obstructive sleep apnoea treated with continuous positive airway pressure; investigation with more complex studies; sleep physician appointment; no or non-severe sleep disorder for general practitioner management. Assessment numbers increased steadily (~400 in 2007 vs. 1400 in 2015). Median time from referral to assessment and multi-disciplinary meeting was 28 and 48 days, respectively. After the first multi-disciplinary meeting, 23% of cases were assessed as having severe obstructive sleep apnoea. More complex studies (mostly flow based) were required in 49% of patients, identifying severe obstructive sleep apnoea in a further 13%. Thirty-seven percent of patients had obstructive sleep apnoea severe enough to qualify for funded treatment. Forty-eight percent of patients received a definitive answer from the first multi-disciplinary meeting. Median time from referral to continuous positive airway pressure for 'at risk' patients with severe obstructive sleep apnoea, e.g., commercial drivers, was 49 days, while patients with severe obstructive sleep apnoea but not 'at risk' waited 261 days for continuous positive airway pressure. Ten percent of patients required polysomnography, and 4% saw a sleep specialist. In conclusion, establishment of a community sleep assessment service and sleep multi-disciplinary meeting led to significantly more assessments, with short waiting times for treatment, especially in high-risk patients with severe obstructive sleep apnoea. Most patients can be assessed without more complex studies or face-to-face review by a sleep specialist. SLEEP DISORDERS: MORE ASSESSMENTS, SHORTER WAITS WITH COMMUNITY SLEEP SERVICE: A community-based service for common sleep disorders can provide rapid and easily accessed sleep assessment and treatment. A team led by Michael Hlavac and Michael Epton from Christchurch Hospital describe the creation of a sleep assessment service within the Canterbury district of New Zealand, in which initial assessments are conducted throughout the community by general practice teams under guidance and advice from sleep specialists at the region's largest hospital. Before the service, there were around 300 sleep assessments per year in all of Canterbury, a region with a population of around 510,000. Now, that number has more than tripled, with shorter waiting times for treatment, especially for people with severe sleep apnoea. The authors conclude that most patients can be assessed for a suspected sleep disorder without needing to visit a hospital's sleep unit.

RESUMEN

Chronic smoking is associated with endothelial dysfunction and inflammation, with oxidative stress contributing to both these processes. In this study, we investigated the effect of combined antioxidant treatment with Enzogenol, a flavonoid extract from the bark of Pinus radiata and vitamin C, over and above vitamin C alone, on endothelial function, plasma markers of inflammation and oxidative stress, blood pressure (BP) and anthropometrics. Forty-four chronic smokers without established cardiovascular disease were assigned randomly to receive either 480 mg Enzogenol and 60 mg vitamin C, or 60 mg vitamin C alone daily for 12 weeks. Endothelial function in the brachial artery was assessed by flow-mediated vasodilation (FMD). FMD improved in both treatment groups (p < 0.001), with no significant difference between the two groups (p = 0.84). In the group receiving Enzogenol and vitamin C, protein carbonyl levels were significantly reduced compared to the group taking vitamin C alone (p = 0.03). Enzogenol and vitamin C resulted in a significant reduction in fibrinogen levels in heavy smokers compared with vitamin C alone (p < 0.009). These findings demonstrated that co-supplementation with Enzogenol and vitamin C in smokers conferred no additional beneficial effect on macrovascular endothelial function over and above that seen in the vitamin C alone group. However, Enzogenol did demonstrate additional favourable effects on protein oxidative damage and fibrinogen levels.

RESUMEN

AIM: To evaluate the safety and effectiveness of a clinical pathway for investigation of postmenopausal bleeding (PMB), managed primarily by general practitioners. Women with an endometrial thickness (ET) ≥5mm on transvaginal ultrasound (TVUS) require either a pipelle biopsy in primary care or referral for specialist care. METHOD: Data on 241 women with PMB were reviewed retrospectively over a 5-year follow-up period. Twenty-five women were excluded as they did not satisfy PMB clinical pathway criteria. RESULTS: TVUS showed 121 women had an ET <5mm, 83 an ET ≥5mm, and 12 an endometrial polyp. In the women with ET ≥5mm, 38 had a pipelle biopsy performed in primary care, 36 were referred directly to secondary care, and 9 declined further investigations. Only 17 pipelle biopsies provided sufficient tissue, with the remaining 21 women referred to secondary care. Seven cases of endometrial cancer were identified, 4 by pipelle biopsy and 3 by hysteroscopy. Of the study cohort, 68% were managed solely by their general practitioner to the point of diagnosis, while 81% with an ET ≥5mm required management in secondary care at some stage. No further cases of endometrial cancer were identified in reviews of patient medical records and cancer registries. CONCLUSION: Community-based investigation of PMB is an alternative model of care with no evidence of additional risks to the patient. Targeted education of general practitioners on pipelle biopsies is essential to maximise the effectiveness of the pathway.

RESUMEN

AIM: An online survey was used to determine the perceptions of healthcare professionals in Canterbury on HealthPathways, a website that provides clinical and referral information for general practice teams, relevant to locally available health services and resources. METHOD: The survey questionnaire included questions on the effectiveness and ease-of-use of the website, computer literacy and use of online clinical guidance systems. Differences in the responses between work groups were analysed using the Mann-Whitney test. RESULTS: 249/480 (52%) of general practitioners, 72/156 (46%) of practice nurses, and 43/66 (65%) of hospital clinicians completed the questionnaire. Approximately 90-95% of general practice teams considered the website was easy to use and had contributed to both an increase and improvement of care in the community, with about 50% stating that it had improved their relationships with patients and hospital clinicians. Minor concerns included the website's increasing size and prescriptive nature and that it increased the duration of a patient consultation. Approximately 60% of hospital clinicians reported improvements in referral quality and triage and working relationships with general practices since the introduction of HealthPathways. CONCLUSION: HealthPathways has achieved a high level of acceptance in both primary and secondary care, and has therefore acted as a valuable change management tool increasing healthcare integration in Canterbury.
