RESUMEN
BACKGROUND: Early detection and intervention for chronic obstructive pulmonary disease (COPD) could potentially slow disease progress and minimize harm. OBJECTIVES: To assess the effectiveness of early intervention by a practice nurse-GP team on quality of life (QoL) and process of care in patients with newly diagnosed COPD, compared with usual care. Nurses and GPs in intervention practices were educated to develop and implement disease management plans for COPD. METHODS: A 12-month, multicentre, pragmatic randomized controlled trial with blinded outcome assessment was conducted. Participants were current and former smokers aged 40 to 85 years newly identified as having COPD on post-bronchodilator spirometry. The primary outcome was health-related QoL, assessed with the St George's Respiratory Questionnaire (SGRQ). Secondary outcome measures were other QoL measures, lung function, disease knowledge, smoking and immunization status, inhaler technique and health service use. RESULTS: Of the 10 234 patients from 36 practices in Sydney invited to a case-finding appointment, 1641 (16%) attended and 287 (18%) were diagnosed with COPD. Nineteen practices (144 patients) were randomized to the intervention group and 17 practices (110 patients) to the control group. Only 15.3% (n = 22) patients in the intervention group saw the nurse for COPD care following case finding. There was no between-group difference in SGRQ score at follow-up (mean difference -0.21; P = 0.86). Influenza vaccination was higher in the intervention group (OR 2.31: P = 0.035), but there were no other significant between-group differences in outcomes. CONCLUSION: Intervention uptake was low and had no additional beneficial effect, over usual care, on participants' health-related QoL.

OBJECTIVE: In 2002, New South Wales (NSW) Health introduced an updated policy for occupational screening and vaccination against infectious diseases. This study describes healthcare worker (HCW) immunity to hepatitis B, measles, mumps, rubella (MMR) and varicella based on serological screening, following introduction of this policy. METHODS: HCW screening serology performed at two healthcare facilities in south western Sydney (Bankstown and Fairfield) was extracted for the period September 2003 to September 2005. Immunity to hepatitis B, MMR and varicella was quantitated and cross-tabulated against age, sex and staff risk category. RESULTS: A total of 1,320 HCWs were screened. Almost two thirds were immune to hepatitis B while immunity to MMR and varicella ranged from 88% to 94%. Age stratification showed lower levels of measles immunity in those born after 1965. CONCLUSIONS: Despite availability of vaccination for over two decades, a significant proportion of HCWs at these two facilities were non-immune to hepatitis B. This is of concern for those non-immune staff involved in direct clinical care, who are at risk of blood and body fluid exposures. The small group of HCWs non-immune to MMR and varicella pose a risk to themselves and others in the event of an outbreak. IMPLICATIONS: There is a need for improved implementation of the occupational screening and vaccination policy, including better education of HCWs about the risks of non-immunity to vaccine preventable diseases. The revised 2007 NSW Health policy may assist this process and will need evaluation to determine whether HCW immunity improves in the coming years.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of disability, hospitalization, and premature mortality. General practice is well placed to diagnose and manage COPD, but there is a significant gap between evidence and current practice, with a low level of awareness and implementation of clinical practice guidelines. Under-diagnosis of COPD is a world-wide problem, limiting the benefit that could potentially be achieved through early intervention strategies such as smoking cessation, dietary advice, and exercise. General practice is moving towards more structured chronic disease management, and the increasing involvement of practice nurses in delivering chronic care. DESIGN: A pragmatic cluster randomised trial will test the hypothesis that intervention by a practice nurse-general practitioner (GP) team leads to improved health-related quality of life and greater adherence with clinical practice guidelines for patients with newly-diagnosed COPD, compared with usual care. Forty general practices in greater metropolitan Sydney Australia will be recruited to identify patients at risk of COPD and invite them to attend a case finding appointment. Practices will be randomised to deliver either practice nurse-GP partnership care, or usual care, to patients newly-diagnosed with COPD.The active intervention will involve the practice nurse and GP working in partnership with the patient in developing and implementing a care plan involving (as appropriate), smoking cessation, immunisation, pulmonary rehabilitation, medication review, assessment and correction of inhaler technique, nutritional advice, management of psycho-social issues, patient education, and management of co-morbidities.The primary outcome measure is health-related quality of life, assessed with the St George's Respiratory Questionnaire 12 months after diagnosis. Secondary outcome measures include validated disease-specific and general health related quality of life measures, smoking and immunisation status, medications, inhaler technique, and lung function. Outcomes will be assessed by project officers blinded to patients' randomization groups. DISCUSSION: This study will use proven case-finding methods to identify patients with undiagnosed COPD in general practice, where improved care has the potential for substantial benefit in health and healthcare utilization. The study provides the capacity to trial a new model of team-based assessment and management of newly diagnosed COPD in Australian primary care. TRIAL REGISTRATION: ACTRN12610000592044\
