Impact of an integrated community-based model of care for older people with complex conditions on hospital emergency presentations and admissions: a step-wedged cluster randomized trial.

BACKGROUND: Health systems must reorient towards preventative and co-ordinated care to reduce hospital demand and achieve positive and fiscally responsible outcomes for older persons with complex needs. Integrated care models can improve outcomes by aligning primary practice with the specialist health and social services required to manage complex needs. This paper describes the impact of a community-facing program that integrates care at the primary-secondary interface on the rate of Emergency Department (ED) presentation and hospital admissions among older people with complex needs. METHODS: The Older Persons Enablement and Rehabilitation for Complex Health Conditions (OPEN ARCH) study is a multicentre randomised controlled trial with a stepped wedge cluster design. General practitioners (GPs; n = 14) in primary practice within the Cairns region are considered 'clusters' each comprising a mixed number of participants. 80 community-dwelling persons over 70 years of age if non-Indigenous and over 50 years of age if Indigenous were included at baseline with no new participants added during the study. Clusters were randomly assigned to one of three steps that represent the time at which they would commence the OPEN ARCH intervention, and the subsequent intervention duration (3, 6, or 9 months). Each participant was its own control. GPs and participants were not blinded. The primary outcomes were ED presentations and hospital admissions. Data were collected from Queensland Health Casemix data and analysed with multilevel mixed-effects Poisson regression modelling to estimate the effectiveness of the OPEN ARCH intervention. Data were analysed at the cluster and participant levels. RESULTS: Five clusters were randomised to steps 1 and 2, and 4 clusters randomised to step 3. All clusters (n = 14) completed the trial accounting for 80 participants. An effect size of 9% in service use (95% CI) was expected. The OPEN ARCH intervention was found to not make a statistically significant difference to ED presentations or admissions. However, a stabilising of ED presentations and a trend toward lower hospitalisation rates over time was observed. CONCLUSIONS: While this study detected no statistically significant change in ED presentations or hospital admissions, a plateauing of ED presentation and admission rates is a clinically significant finding for older persons with complex needs. Multi-sectoral integrated programs of care require an adequate preparation period and sufficient duration of intervention for effectiveness to be measured. TRIAL REGISTRATION: The OPEN ARCH study received ethical approval from the Far North Queensland Human Research Ethics Committee, HREC/17/QCH/104-1174 and is registered on the Australian and New Zealand Trials Registry, ACTRN12617000198325p .

Medical emergencies in dental practice - management requirements and international practitioner proficiency. A scoping review.

The management of medical emergencies is widely considered a requisite skill for all dentists. Timely intervention of an emergency can significantly alter the outcome for a patient's morbidity and possible mortality. This scoping review examines the prevalence of medical emergencies in dental practice, as well as dentists' attitude, confidence, and competence, of medical emergency management within a dental setting. Key findings include a lack of preparedness towards medical emergencies, despite a universal recognition of the importance and desire to improve key medical skills.

Development of a risk prediction model for Barrett's esophagus in an Australian population.

Esophageal adenocarcinoma has poor 5-year survival rates. Increased survival might be achieved with earlier treatment, but requires earlier identification of the precursor, Barrett's esophagus. Population screening is not cost effective, this may be improved by targeted screening directed at individuals more likely to have Barrett's esophagus. To develop a risk prediction tool for Barrett's esophagus, this study compared individuals with Barrett's esophagus against population controls. Participants completed a questionnaire comprising 35 questions addressing medical history, symptom history, lifestyle factors, anthropomorphic measures, and demographic details. Statistical analysis addressed differences between cases and controls, and entailed initial variable selection, checking of model assumptions, and establishing calibration and discrimination. The area under the curve (AUC) was used to assess overall accuracy. One hundred and twenty individuals with Barrett's esophagus and 235 population controls completed the questionnaire. Significant differences were identified for age, gender, reflux history, family reflux history, history of hypertension, alcoholic drinks per week, and body mass index. These were used to develop a risk prediction model. The AUC was 0.82 (95% CI 0.78-0.87). Good calibration between predicted and observed risk was noted (Hosmer-Lemeshow test P = 0.67). At the point minimizing false positives and false negatives, the model achieved a sensitivity of 84.96% and a specificity of 66%. A well-calibrated risk prediction model with good discrimination has been developed to identify patients with Barrett's esophagus. The model needs to be externally validated before consideration for clinical practice.

Effect of a general practitioner management plan on health outcomes and hospitalisations in older patients with diabetes.

BACKGROUND: Little is known about the impact of a general practitioner management plan (GPMP) on health outcomes of patients with diabetes. AIM: To examine the impact of a GPMP on the risk of hospitalisation for diabetes. METHODS: A retrospective study using administrative data from the Australian Government Department of Veterans' Affairs was conducted (1 July 2006 to 30 June 2014) of diabetes patients either exposed or unexposed to a GPMP. The primary end-point was the risk of first hospitalisation for a diabetes-related complication and was assessed using Cox proportional hazard regression models with death as a competing risk. Secondary end-points included rates of receiving guideline care for diabetes, with differences assessed using Poisson regression analyses. RESULTS: A total of 16 214 patients with diabetes were included; 8091 had a GPMP, and 8123 did not. After 1 year, 545 (6.7%) patients with a GPMP and 634 (7.8%) of patients without a GPMP were hospitalised for a diabetes complication. There was a 22% reduction in the risk of being hospitalised for a diabetes complication (adjusted hazard ratio (HR) 0.78, 95% confidence interval (CI) 0.69-0.87, P < 0.0001) for those who received a GPMP by comparison to those who did not. Increased rates of diabetes guideline care, HbA1c claims (adjusted HR 1.29, 95% CI 1.25-1.33) and microalbuminura claims (adjusted HR 1.65, 95% CI 1.58-1.72) were observed after a GPMP. CONCLUSION: Provision of a GPMP in older patients with diabetes resulted in improved health outcomes, delaying the risk of hospitalisation at 12 months for diabetes complications. GPMP should be included as part of routine primary care for older patients with diabetes.

Management of Indigenous patients presenting with non ST-segment elevation acute coronary syndrome in South Australia: a retrospective cohort study.

AIM: Using Australian guidelines for management of acute coronary syndromes, we assessed the probability of an Indigenous patient receiving interventional and therapeutic care after presenting in two metropolitan hospitals. METHODS: A retrospective case note review of patients admitted through two Adelaide public tertiary hospital emergency departments from December 2007 to December 2009. The study cohort was 488 patients with high-risk clinical features without ST-segment elevation. RESULTS: Indigenous patients were significantly younger, present later in the disease process and have a higher burden of cardiovascular risk factors when compared with non-Indigenous patients. Indigenous patients were 54% more likely to receive angiography (Risk ratios (RR) = 1.54; 95% CI 1.31; 1.81) than non-Indigenous patients, however, this difference disappeared after adjustment for age, sex and propensity score. Indigenous patients were 20% more likely to receive the recommended medications (RR = 1.19, 95% CI 1.01; 1.40) compared with non-Indigenous patients. Patients over 65 years were 53% less likely to receive an angiogram (RR = 0.47, 95% CI 0.38; 0.56) and were 35% less likely to receive the recommended medications (RR = 0.65, 95% CI 0.54; 0.78) than a patient at the ages of 18-49. Women were almost 20% less likely to receive an angiogram (RR = 0.81, 95% CI 0.66; 0.99) and 20% less likely to receive the recommended medications (RR = 0.80, 95% CI 0.71; 0.91) when compared with men. The likelihood of receiving medications on discharge was significantly influenced by age, gender, ethnicity, comorbid burden and revascularisation. CONCLUSIONS: The younger age and significantly higher-risk profile of Indigenous adults presenting to SA hospitals with acute coronary syndromes appears to lead to different management decisions, which may well be led by patient factors. Many of these risk conditions can be better managed in the primary care setting.

Love, faith and hope - a secondary analysis of prostate cancer survivors and their partners.

BACKGROUND: Men's experience of recovery from treatment for prostate cancer has been extensively researched with reports highlighting the physical side effects of treatments such as erectile dysfunction and incontinence. The psychological, emotional and spiritual burden of prostate cancer on men and their partners has received far less attention. DESIGN: In this study, a secondary thematic analysis of data from a series of separate but related qualitative studies with prostate cancer survivors and their partners was conducted to further explore themes of love, hope and faith within this population. RESULTS: This study identified unresolved needs related to the emotive concepts of love, hope and faith. The findings from this study can be employed to refine psychosocial assessments of men with prostate cancer, and provide a more comprehensive understanding of prostate cancer survivors supportive care needs.

Efficacy of a basal bolus insulin protocol to treat prednisolone-induced hyperglycaemia in hospitalised patients.

BACKGROUND/AIM: Few studies have specifically investigated treatment of prednisolone-induced hyperglycaemia. AIM: To determine if a basal bolus insulin (BBI) protocol for inpatient hyperglycaemia is effective in patients prescribed acute prednisolone for an inflammatory disease. METHODS: In a cross-sectional study, 66 patients with type 2 diabetes admitted to a general medical ward and treated with BBI for up to 5 days were studied. Twenty-four patients were taking prednisolone ≥10 mg/day to treat an acute inflammatory disease. The remaining 42 patients were a control group. The primary outcome was mean daily blood glucose level. RESULTS: There were no significant differences in glycosylated haemoglobin (8.1 ± 1.0 vs 8.1 ± 1.6%, P = 0.88), age (77 ± 11 vs 75 ± 14 years, P = 0.57), male sex (63 vs 60%, P = 0.81) or body mass index (30.0 ± 5.3 vs 30.2 ± 11.5 kg/m(2) , P = 0.90) between patients taking prednisolone and controls. Mean daily glucose concentration was higher in patients taking prednisolone than in controls (12.2 ± 0.3 vs 10.0 ± 0.1 mmol/L, P < 0.001). Blood glucose level was higher in patients on prednisolone at 1700 h (14.6 ± 0.6 vs 10.3 ± 0.3 mmol/L, P < 0.001) and 2100 h (14.5 ± 0.6 vs 10.5 ± 0.3 mmol/L, P < 0.001), with no significant differences at 0700 h and 1200 h. These findings occurred despite patients taking prednisolone receiving a higher daily insulin dose than controls (0.67-0.70 vs 0.61-0.65 U/kg, P = 0.001) because of higher doses of ultra-rapid-acting insulin at 1200 h and 1700 h. CONCLUSIONS: Hospitalised patients taking prednisolone had substantial afternoon and evening hyperglycaemia despite receiving BBI via a protocol for inpatient hyperglycaemia. Specific insulin regimens for prednisolone-induced hyperglycaemia are needed that recommend more insulin during this time period.

General practitioner management plans delaying time to next potentially preventable hospitalisation for patients with heart failure.

BACKGROUND: Several studies have shown that the Australian Medicare-funded chronic disease management programme can lead to improvements in care processes. No study has examined the impact on long-term health outcomes. AIMS: This retrospective cohort study assessed the association between provision of a general practitioner management plan and time to next potentially preventable hospitalisation for older patients with heart failure. METHODS: We used the Australian Government Department of Veterans' Affairs (DVA) claims database and compared patients exposed to a general practitioner management plan with those who did not receive the service. Kaplan-Meier analysis and Cox proportional hazards models were used to compare time until next potentially preventable hospitalisation for heart failure between the exposed and unexposed groups. RESULTS: There were 1993 patients exposed to a general practitioner management plan and 3986 unexposed patients. Adjusted results showed a 23% reduction in the rate of potentially preventable hospitalisation for heart failure at any time (adjusted hazard ratio, 0.77; 95% confidence interval, 0.64 to 0.92; P = 0.0051) among those with a general practitioner management plan compared with the unexposed patients. Within one year, 8.6% of the exposed group compared with 10.7% of the unexposed group had a potentially preventable hospitalisation for heart failure. CONCLUSIONS: A general practitioner management plan is associated with delayed time to next potentially preventable hospitalisation for heart failure.

Survival of bacteria on the ocular surface following double application of povidone-iodine before cataract surgery.

AIMS: This study assessed the effectiveness of one vs two applications of povidone-iodine in decontaminating the eye before cataract surgery. METHODS: This was a prospective, interventional study of 52 patients having elective unilateral phacoemulsification cataract surgery in a tertiary care centre. Each patient had two applications of povidone-iodine before phacoemulsification cataract surgery, separated by 10 min. Conjunctival swabs were taken before and after each application and cultured in 5% CO(2) and anaerobically. Statistical analysis was performed using McNemar's test for correlated proportions. RESULTS: In all, 15 of 52 (29%) patients had positive cultures before the first application and 21 of 52 (40%) patients had positive cultures after it. This was not statistically significant (P=0.239). A total of 25 of 52 (48%) patients were culture positive before the second application. This was not statistically significantly different from 10 min earlier (P=0.423). Six of 52 (12%) patients were positive after the second application (P<0.001). CONCLUSIONS: We conclude that the initial application of povidone-iodine was not effective in decontaminating the eye. Recontamination did not take place between applications. The difference in the proportion of patients with positive results before and after the second application of povidone-iodine was statistically significant. We infer from this that double application of povidone-iodine before cataract surgery is advisable.

Tumour-infiltrating lymphocytes and survival in patients with adenocarcinoma of the oesophagus.

INTRODUCTION: Tumor-infiltrating lymphocytes (TILs) and forkhead box transcription factor positive (FoxP3(+)) regulatory T-lymphocytes (TREGs) have been analyzed in a variety of tumors but not in oesophageal adenocarcinoma. PATIENTS AND METHODS: Tissue from 130 adenocarcinomas of the oesophagus was re-evaluated in the centre and periphery of tumour, respectively, using immunohistochemical staining with anti-CD3, anti-CD4, anti-CD8, anti-CD25 and anti-FoxP3 antibodies. Patients were stratified according neoadjuvant treatment. 106 patients proceeded directly to surgery and 24 underwent pre-operative radio-chemotherapy (RCT). RESULTS: In patients without RCT, TILs were found significantly more frequently in the periphery with the exception of CD25(+) cells. Patients with centrally low counts of FoxP3(+) TREGs had higher tumour stages than patients with high counts (p < 0.011). The number of FoxP3(+) TREGs was significantly associated with the number of CD8(+) cells (centre: p < 0.001, periphery: p = 0.002). The multivariate regression analysis identified UICC stage (IIB/III vs. I/IIA, hazard ratio 2.6, p = 0.011) and completeness of resection (no vs. yes, hazard ratio 2.3, p = 0.015) as independent predictors of survival. RCT significantly reduced the number of TREGs in the centre (p = 0.016) but not the number of the other TILs. CONCLUSION: UICC stage and completeness of resection but none of the TILs were prognostic markers for long-term survival. We found no morphologic evidence that TREGs suppress immunological response, represented by the infiltration of CD8(+) cells. Preoperative RCT affected the centre of tumours more than the periphery, which may indicate that it does not inhibit the host-to-tumour reaction. RCT affects TREGs more than the other TILs.

Peri-operative use of dexmedetomidine in airway reconstruction surgery for obstructive sleep apnoea.

OBJECTIVE: To evaluate the peri-operative usefulness of dexmedetomidine in obstructive sleep apnoea surgery. METHODS: In a clinical audit, patients were divided into a study group (dexmedetomidine used; n = 125; 82.9 per cent males, 17.1 per cent females; mean age 48.1 years) and a control group (dexmedetomidine not used; n = 143; 85.5 per cent males, 14.5 per cent females; mean age 47.4 years). The selected outcome measures were mean arterial pressure, use of anti-hypertensives and use of opioids. RESULTS: Mean arterial pressure was stable (i.e. below 100 mmHg) in 93.3 per cent of the study group and 72.0 per cent of the control group (relative risk 1.30, 95 per cent confidence interval 1.14-1.47). The use of glyceryl trinitrate and hydralazine was significantly less in the study group, compared with controls (p = 0.005 and <0.001, respectively). Study group patients underwent more procedures than control patients (p < 0.001) and were more likely to require morphine. No difference was noted in the median dose of opioids. CONCLUSION: Dexmedetomidine improves haemodynamic stability in patients undergoing surgery for obstructive sleep apnoea. It is reliable and reduces the need for polypharmacy. Its opioid-sparing action has been established in the literature; however, this was not demonstrated in our study.

Providing reviews of evidence to COPD patients: controlled prospective 12-month trial.

The aim of this study was to evaluate a novel patient-held manual designed to reduce the evidence-practice gap in chronic obstructive pulmonary disease (COPD). The intervention manual contained summaries of research evidence. It was developed using current best practice for patient information materials and designed to cause discussion of evidence between patient and doctor. A controlled before-and-after study was employed in two similar but geographically separate regions of metropolitan Adelaide, South Australia. Participants had moderate to severe COPD, with 249 included at baseline and 201 completing the study. Evidence-based COPD management was measured using an indicator with three components: rates of influenza vaccination, bone density testing, and pulmonary rehabilitation. A survey of behavioral steps leading to practice change was conducted with the trial. Analysis, by median split of socioeconomic disadvantage, showed significant difference between study arms for only one component of the indicator of evidence-based practice, enrollment in pulmonary rehabilitation and only for the most socioeconomically disadvantaged stratum. For both socioeconomic strata, more intervention participants than control participants reported remembering being given the information material, reading part or all, and finding it very or quite helpful. Other significant differences were restricted to the stratum of greatest socioeconomic disadvantage: reading all of the material, learning from it, referring back, and talking to a doctor about a topic from the material. Above 90% of all participants who received the manual reported reading from it, 42% reported discussing topics with a doctor, but only 10% reported treatment change attributable to the manual. We have found that people with COPD will read an evidence manual developed using current best practice. However, the study demonstrated improvement for only one of the three components of an indicator of evidence-based disease management for only the most socioeconomically disadvantaged stratum of participants. Future interventions should be designed to better translate reading uptake into evidence-based disease management.

Nocturnal non-invasive nasal ventilation in stable hypercapnic COPD: a randomised controlled trial.

BACKGROUND: Sleep hypoventilation has been proposed as a cause of progressive hypercapnic respiratory failure and death in patients with severe chronic obstructive pulmonary disease (COPD). A study was undertaken to determine the effects of nocturnal non-invasive bi-level pressure support ventilation (NIV) on survival, lung function and quality of life in patients with severe hypercapnic COPD. METHOD: A multicentre, open-label, randomised controlled trial of NIV plus long-term oxygen therapy (LTOT) versus LTOT alone was performed in four Australian University Hospital sleep/respiratory medicine departments in patients with severe stable smoking-related COPD (forced expiratory volume in 1 s (FEV1.0) <1.5 litres or <50% predicted and ratio of FEV1.0 to forced vital capacity (FVC) <60% with awake arterial carbon dioxide tension (PaCO2) >46 mm Hg and on LTOT for at least 3 months) and age <80 years. Patients with sleep apnoea (apnoea-hypopnoea index >20/h) or morbid obesity (body mass index >40) were excluded. Outcome measures were survival, spirometry, arterial blood gases, polysomnography, general and disease-specific quality of life and mood. RESULTS: 144 patients were randomised (72 to NIV + LTOT and 72 to LTOT alone). NIV improved sleep quality and sleep-related hypercapnia acutely, and patients complied well with therapy (mean (SD) nightly use 4.5 (3.2) h). Compared with LTOT alone, NIV (mean follow-up 2.21 years, range 0.01-5.59) showed an improvement in survival with the adjusted but not the unadjusted Cox model (adjusted hazard ratio (HR) 0.63, 95% CI 0.40 to 0.99, p = 0.045; unadjusted HR 0.82, 95% CI 0.53 to 1.25, p = NS). FEV1.0 and PaCO2 measured at 6 and 12 months were not different between groups. Patients assigned to NIV + LTOT had reduced general and mental health and vigour. CONCLUSIONS: Nocturnal NIV in stable oxygen-dependent patients with hypercapnic COPD may improve survival, but this appears to be at the cost of worsening quality of life. TRIAL REGISTRATION NUMBER: ACTRN12605000205639.

Pain versus bleeding risk following tonsillectomy: do patients and doctors agree?

OBJECTIVE: To investigate the differing opinions of patients and medical practitioners regarding the relative priorities of pain relief versus bleeding prevention following tonsillectomy. METHODS: Questionnaires were mailed out to adult patients, paediatric patients' parents, general practitioners and ENT surgeons. RESULTS: A total of 72/112 (64.3 per cent) questionnaires were returned. Adult patients, paediatric patients' parents, general practitioners and ENT surgeons all ranked bleeding as the most important factor when assessing risks related to tonsillectomy. Most adult patients indicated that they would accept a bleeding risk of 2 per cent; however, parents indicated that they would accept a higher bleeding risk (3 per cent) for their children in exchange for better pain control. CONCLUSIONS: Adult patients, paediatric patients' parents and doctors were slightly more inclined to 'trade-off' an increased post-tonsillectomy bleeding risk in exchange for better post-tonsillectomy pain control, although concerns about post-operative haemorrhage remained the main priority for all groups.

Risk prediction scores for postoperative mortality after esophagectomy: validation of different models.

BACKGROUND: Different prediction models for operative mortality after esophagectomy have been developed. The aim of this study is to independently validate prediction models from Philadelphia, Rotterdam, Munich, and the ASA. METHODS: The scores were validated using logistic regression models in two cohorts of patients undergoing esophagectomy for cancer from Switzerland (n = 170) and Australia (n = 176). RESULTS: All scores except ASA were significantly higher in the Australian cohort. There was no significant difference in 30-day mortality or in-hospital death between groups. The Philadelphia and Rotterdam scores had a significant predictive value for 30-day mortality (p = 0.001) and in-hospital death (p = 0.003) in the pooled cohort, but only the Philadelphia score had a significant prediction value for 30-day mortality in both cohorts. Neither score showed any predictive value for in-hospital death in Australians but were highly significant in the Swiss cohort. ASA showed only a significant predictive value for 30-day mortality in the Swiss. For in-hospital death, ASA was a significant predictor in the pooled and Swiss cohorts. The Munich score did not have any significant predictive value whatsoever. CONCLUSION: None of the scores can be applied generally. A better overall predictive score or specific prediction scores for each country should be developed.

Influence of rheumatoid arthritis on work participation in Australia.

BACKGROUND: The aim of the study was to determine the prevalence of work disability in a cohort of Australians with rheumatoid arthritis. METHODS: A cross-sectional study of a sample of 497 individuals aged 18-65 years with rheumatoid arthritis in Adelaide, South Australia, was carried out. RESULTS: Of those employed, 130 (51%) were in full-time employment (> or= 35 h per week) work and 124 (49%) were in part-time employment (average 20 h per week). Overall, the observed/expected numbers working were 254/316 (relative risk 0.8 (0.69-0.91)). Using a comparator adjusted by removing those on the disability support pension, the relative risk of the working was 0.74. The observed/expected numbers working part time in the study group were 124/89 (relative risk 1.4 (1.25-1.65)). Those who continued to work had lower Health Assessment Questionnaire scores, less morning stiffness, superior scores for patient assessed level of function, lower pain scores, lower joint counts, a lower C-reactive protein, better measures of 'patient global assessment' and higher levels of education compared with the group who had ceased work. Overall, of those working at the time of diagnosis, 20% had ceased work within 5 years and approximately 40% had ceased work by 20 years. Of those who ceased work, the mean duration from time of diagnosis to work cessation was 7 years with half the subjects who ceased work doing so within 4 years of diagnosis. CONCLUSION: Work disability associated with rheumatoid arthritis in Australia is very significant and costly. Work disability occurs relatively early in the disease and is associated with several identifiable variables, many of which may be amenable to intervention strategies.

The effect of rheumatoid arthritis on personal income in Australia.

BACKGROUND: The aim of this study was to estimate the effect of rheumatoid arthritis (RA) on the personal income of a cohort of individuals with RA in Australia. METHODS: A cross-sectional study of a sample of 497 working age people with RA in Adelaide, South Australia was carried out. RESULTS: The average personal income of an individual with RA in our cohort in 2003-2004 was $A22 400 compared with the Australian mean annual income of $A38 000. When standardized, the income of our cohort was 66% that of the average income of the Australian population. Overall one-third of the RA cohort relied principally on the social security system for their income and more than 75% of the cohort estimated they had lost greater than $A10 000 per annum in personal income as a result of their disease. Individuals with RA who were not working had annual incomes on average of more than $A20 000 less than those who continued to work. CONCLUSION: The personal income loss associated with RA in Australia is of enormous significance. It reduces a large population of individuals to relative financial poverty and potentially limits their access to a range of services including private health services.

An advance notification letter increases participation in colorectal cancer screening.

OBJECTIVES: To determine the impact of novel invitation strategies on population participation in faecal immunochemical test (FIT)-based colorectal cancer (CRC) screening. SETTING: A community screening programme in Adelaide, South Australia. METHODS: In total, 2400 people aged 50-74 years were randomly allocated to one of four CRC screening invitation strategies: (a) CONTROL: standard invitation-to-screen letter explaining risk of CRC and the concept, value and method of screening; (b) Risk: invitation with additional messages related to CRC risk; (c) Advocacy: invitation with additional messages related to advocacy for screening from previous screening programme participants and (d) Advance Notification: first, a letter introducing CONTROL letter messages followed by the standard invitation-to-screen. Invitations included an FIT kit. Programme participation rates were determined for each strategy relative to control. Associations between participation and sociodemographic variables were explored. RESULTS: At 12 weeks after invitation, participation was: CONTROL: 237/600 (39.5%); Risk: 242/600 (40.3%); Advocacy: 216/600 (36.0%) and Advance Notification: 290/600 (48.3%). Participation was significantly greater than CONTROL only in the Advance Notification group (Relative risk [RR] 1.23, 95% confidence interval [CI] 1.06-1.43). This effect was apparent as early as two weeks from date of offer; Advance Notification: 151/600 (25.2%) versus CONTROL: 109/600 (18.2%, RR 1.38, 95% CI 1.11-1.73). CONCLUSIONS: Advance notification significantly increased screening participation. The effect may be due to a population shift in readiness to undertake screening, and is consistent with the Transtheoretical Model of behaviour change. Risk or lay advocacy strategies did not improve screening participation. Organized screening programmes should consider using advance notification letters to improve programme participation.

Screening for colorectal cancer by faecal occult blood test: why people choose to refuse.

To better understand the personal barriers that limit participation in faecal occult blood test (FOBT) screening for colorectal cancer, non-participants from a recent screening initiative were sent detailed questionnaires, defining their reasons for not participating, as well as how to make screening more attractive. The important barrier was procrastination. The type of FOBT kit offered influenced the reasons for not participating. Convenient FOBT and greater general practitioner involvement may be important for optimizing community acceptance of FOBT-based screening.

Providing patients with reviews of evidence about COPD treatments: a controlled trial of outcomes.

Studies in many countries have identified gaps between what is known from research evidence and what is done in clinical practice. Merely making research evidence available to practitioners does not cause much change in their behaviour, and researchers are now looking for more effective ways to improve the implementation of evidence. We report outcomes at three months of a parallel group trial of an evidence based patient manual designed to improve implementation of evidence by the patient's doctors. The patient manual was produced with extensive patient and professional input. It contained summaries of the evidence for treatments used in COPD (chronic obstructive pulmonary disease) and prompted discussion of evidence with doctors. Participants in the intervention arm of the trial (n = 125) were supplied with the manual and participants in the control arm (n = 124) were supplied with a pamphlet about COPD produced by the Australian Lung Foundation. The primary outcome measure (rates of current influenza vaccination and bone density testing) was an indicator of evidence based management of COPD. Secondary outcomes were quality of life (mastery component), satisfaction with information, communication with usual doctor, and anxiety. At three months no pattern of benefit in outcome measures was found for either group. Process measures showed high levels of personal use of the manual but progression to conversations with doctors for fewer than half of participants, and little treatment change. The findings highlight the difficulties of promoting changes in health behaviour and show that even when all stakeholders are consulted success is not guaranteed. Further research is required to identify those patients most likely to use manuals such as the one reported here, and how to make patient mediated interventions more effective for a greater proportion of the target population.
