The role of high-flow nasal therapy in bronchiectasis: a post hoc analysis.

High-flow nasal therapy significantly reduces exacerbation rates and improves quality of life in patients with stable bronchiectasis. High-flow nasal therapy is therefore a potential treatment option for patients with bronchiectasis. https://bit.ly/2JFXuQc.

Population health in New Zealand 2000-2013: From determinants of health to targets.

OBJECTIVE: To determine how 'population health' has been understood in practice and policy and has influenced health system restructuring in New Zealand since 2000. METHODS: Interviews in 2007-2008 with managers, clinicians, government policy advisors and academics were undertaken to explore the relationships between population health, determinants of health, and health system restructuring. This was augmented by a review of major government health policies from 2009 to 2013 to establish which notions of population health were reflected. RESULTS: Population health shifted from a broad notion of health determinants to focus on a small number of quantifiable health targets driven by financial incentives. Meantime, an emphasis on 'quality and safety' impeded population health activities. District Health Board programmes to identify high risk individuals, by disease or hospital service utilisation, diverted attention from broader population health outcomes. District Health Boards were not held accountable for integrating a population health approach in service planning and did not initiate or lead intersectoral work. Community consultation was limited. Primary Health Organisations, although mandated to address population health, typically aligned with the small-business model of general practice making service integration difficult to achieve. In policy, 'population health' dropped from favour in the mid-2000s, although many documents, outside the health sector, carried forward these values. CONCLUSION: A progressively narrower focus on a small number of health targets and on organisational processes undermined earlier policy intentions and health system restructuring that sought to improve broader population health outcomes.

Patients' engagement in primary care: powerlessness and compounding jeopardy. A qualitative study.

BACKGROUND: Primary health care does not adequately respond to populations known to have high needs such as those with compounding jeopardy from chronic conditions, poverty, minority status and age; as such populations report powerlessness. OBJECTIVE: To explore what poor older adults with chronic conditions who mostly belong to ethnic minority groups say they want from clinicians. SETTING AND PARTICIPANTS: Participants were older adults whose chronic conditions were severe enough to require hospital admission more than twice in the previous 12 months. All participants lived in poor localities in Auckland, New Zealand's largest city. METHODS: Forty-two in-depth interviews were conducted and analysed using qualitative description. RESULTS: An outward acceptance of health care belied an underlying dissatisfaction with low engagement. Participants did not feel heard and wanted information conveyed in a way that indicated clinicians understood them in the context of their lives. Powerlessness, anger, frustration and non-concordance were frequent responses. DISCUSSION AND CONCLUSIONS: Despite socio-cultural and disease-related complexity, patients pursue the (unrealised) ideal of an engaged therapeutic relationship with an understanding clinician. Powerlessness means that the onus is upon the health system and the clinician to engage. Engagement means building a relationship on the basis of social, cultural and clinical knowledge and demonstrating a shift in the way clinicians choose to think and interact in patient care. Respectful listening and questioning can deepen clinicians' awareness of patients' most important concerns. Enabling patients to direct the consultation is a way to integrate clinician expertise with what patients need and value.

Helplessness, self blame and faith may impact on self management in COPD: a qualitative study.

AIMS: To explore how patients with COPD experience helplessness. METHODS: In-depth interviews with 29 patients with moderate to very severe COPD. Data were analysed using a general inductive approach. RESULTS: All patients focused on acute symptoms and expressed feelings of helplessness in the management of their condition; little attention was paid to longer-term strategies. For one group of patients, mostly European, self blame appeared to intensify feelings of helplessness. For a second group, mostly Pacific, a focus on faith in God, Church and family provided a more positive affect and existed alongside helplessness. CONCLUSIONS: Clinicians seeking to support patients to include longer term strategies in their self management will need to coach patients to experiences of short-term success, and be aware of the ways that patients experience and interpret their helplessness. Clinicians need to address self blame, and recognise patients' priorities of faith and family.

The clinical utility of long-term humidification therapy in chronic airway disease.

AIM: Persistent airway inflammation with mucus retention in patients with chronic airway disorders such as COPD and bronchiectasis may lead to frequent exacerbations, reduced lung function and poor quality of life. This study investigates if long-term humidification therapy with high flow fully humidified air at 37 degrees C through nasal cannulae can improve these clinical outcomes in this group of patients. METHOD: 108 patients diagnosed with COPD or bronchiectasis were randomised to daily humidification therapy or usual care for 12 months over which exacerbations were recorded. Lung function, quality of life, exercise capacity, and measures of airway inflammation were also recorded at baseline, 3 and 12 months. RESULTS: Patients on long-term humidification therapy had significantly fewer exacerbation days (18.2 versus 33.5 days; p = 0.045), increased time to first exacerbation (median 52 versus 27 days; p = 0.0495) and reduced exacerbation frequency (2.97/patient/year versus 3.63/patient/year; p = 0.067) compared with usual care. Quality of life scores and lung function improved significantly with humidification therapy compared with usual care at 3 and 12 months. CONCLUSION: Long-term humidification therapy significantly reduced exacerbation days, increased time to first exacerbation, improved lung function and quality of life in patients with COPD and bronchiectasis.

Cardiovascular risk factors after antenatal exposure to betamethasone: 30-year follow-up of a randomised controlled trial.

BACKGROUND: Antenatal betamethasone treatment is widely used for the prevention of neonatal respiratory distress syndrome in preterm infants and substantially reduces neonatal mortality and morbidity. Fetal exposure to excess glucocorticoids has been proposed as one of the core mechanisms of the fetal origins of adult disease hypothesis. We assessed whether antenatal exposure to betamethasone for the prevention of neonatal respiratory distress syndrome affects cardiovascular risk factors at 30 years of age. METHODS: We followed up at age 30 years 534 individuals whose mothers participated in a double-blind, placebo-controlled, randomised trial of antenatal betamethasone for the prevention of neonatal respiratory distress syndrome. Mothers received two doses of betamethasone or placebo given by intramuscular injection 24 h apart. Follow-up assessments included anthropometry; measurement of blood pressure, blood lipids (after overnight fasting), and early morning cortisol levels; and a 75 g oral glucose tolerance test. FINDINGS: There were no differences between those exposed to betamethasone and to placebo in body size, blood lipids, blood pressure, plasma cortisol, prevalence of diabetes, or history of cardiovascular disease. After a 75 g oral glucose tolerance test, participants exposed to betamethasone had higher plasma insulin concentrations at 30 min (60.5 vs 52.0 mIU/L; ratio of geometric means 1.16 [95% CI 1.03 to 1.31], p=0.02) and lower glucose concentrations at 120 min (4.8 vs 5.1 mmol/L; difference -0.26 mmol/L [-0.53 to 0.00], p=0.05) than did those exposed to placebo. INTERPRETATION: Antenatal exposure to betamethasone might result in insulin resistance in adult offspring, but has no clinical effect on cardiovascular risk factors at 30 years of age. Thus, obstetricians should continue to use a single course of antenatal betamethasone for the prevention of neonatal respiratory distress syndrome.

The development and implementation of the Chronic Care Management Programme in Counties Manukau.

AIMS: To develop an effective and efficient process for the seamless delivery of care for targeted patients with specific chronic diseases. To reduce inexplicable variation and maximise use of available resources by implementing evidence-based care processes. To develop a programme that is acceptable and applicable to the Counties Manukau region. METHODS: A model for the management of people with chronic diseases was developed. Model components and potential interventions were piloted. For each disease project, a return on investment was calculated and external evaluation was undertaken. The initial model was subsequently modified and individual disease projects aligned to it. RESULTS: The final Chronic Care Management model, agreed in September 2001, described a single common process. Key components were the targeting of high risk patients, organisation of cost effective interventions into a system of care, and an integrated care server acting as a data warehouse with a rules engine, providing flags and reminders. Return on investment analysis suggested potential savings for each disease component from $277 to $980 per person per annum. CONCLUSIONS: For selected chronic diseases, introduction of an integrated chronic care management programme, based on internationally accepted best practice processes and interventions can make significant savings, reducing morbidity and improving the efficiency of health delivery in the Counties Manukau region.
