Effectiveness of IT-based diabetes management interventions: a review of the literature

Background : Information technology (IT) is increasingly being used in general practice to manage health care including type 2 diabetes. However, there is conflicting evidence about whether IT improves diabetes outcomes. This review of the literature about IT-based diabetes management interventions explores whether methodological issues such as sample characteristics, outcome measures, and mechanisms causing change in the outcome measures could explain some of the inconsistent findings evident in IT-based diabetes management studies.

Methods : Databases were searched using terms related to IT and diabetes management. Articles eligible for review evaluated an IT-based diabetes management intervention in general practice and were published between 1999 and 2009 inclusive in English. Studies that did not include outcome measures were excluded.

Results : Four hundred and twenty-five articles were identified, sixteen met the inclusion criteria: eleven GP focussed and five patient focused interventions were evaluated. Nine were RCTs, five non-randomised control trials, and two single-sample before and after designs. Important sample characteristics such as diabetes type, familiarity with IT, and baseline diabetes knowledge were not addressed in any of the studies reviewed. All studies used HbA1c as a primary outcome measure, and nine reported a significant improvement in mean HbA1c over the study period; only two studies reported the HbA1c assay method. Five studies measured diabetes medications and two measured psychological outcomes. Patient lifestyle variables were not included in any of the studies reviewed. IT was the intervention method considered to effect changes in the outcome measures. Only two studies mentioned alternative possible causal mechanisms.

Conclusion : Several limitations could affect the outcomes of IT-based diabetes management interventions to an unknown degree. These limitations make it difficult to attribute changes solely to such interventions.

The impact of patient sex on paramedic pain management in the prehospital setting

Objective: The aim of this study was to establish the impact of patient sex on the provision of analgesia by paramedics for patients reporting pain in the prehospital setting.
Methods: This retrospective cohort study of paramedic patient care records included all adult patients with a Glasgow Coma Score higher than 12 transported to hospital by ambulance in a major metropolitan area over a 7-day period in 2005. Data collected included demographics, patient report of pain and its type and severity, provision of analgesia by paramedics, and type of analgesia provided. The outcomes of interest were sex differences in the provision of analgesia. Data analysis was by descriptive statistics, χ2 test, and logistic regression.
Results: Of the 3357 patients transported in the study period, 1766 (53%) reported pain; this forms the study sample. Fifty-two percent were female, median age was 61 years, and median initial pain score (on a 0-10 verbal numeric rating scale) was 6. Forty-five percent of patients reporting pain did not receive analgesia (791/1766) (95% confidence interval [CI], 43%-47%), with no significant difference between sexes (P = .93). There were, however, significant sex differences in the type of analgesia administered, with males more likely to receive morphine (17%; 95% CI, 15%-20%) than females (13%; 95% CI, 11%-15%) (P = .01). The difference remains significant when controlled for type of pain, age, and pain severity (odds ratio, 0.61, 95% CI, 0.44-0.84).
Conclusion: Sex is not associated with the rate of paramedic-initiated analgesia, but is associated with differences in the type of analgesia administered.

Relationship between hypoactive sexual desire disorder and aging

Objective: Explore the association between Hypoactive Sexual Desire Disorder (HSDD) and aging. The American Foundation of Urologic Disease and the American Psychiatric Association stipulate that HSDD is only diagnosed when both low sexual desire and sexually related personal distress are present.
Design : Community-based, cross-sectional study.
Setting : Europe (UK, Germany, France, Italy) and the USA.
Patient(s) Women aged 20-70 in sexual relationships participating in the Women’s International Study of Health and Sexuality (n=1998 Europe, n=1591 USA).
Intervention(s) : No interventions were administered.
Main Outcome Measures : Self-administered questionnaire that included two validated instruments: Profile of Female Sexual Function© measured sexual desire; Personal Distress Scale© measured sexual distress. Women with low desire and distress were considered to have HSDD.
Results : The proportion of European women with low desire increased from 11% amongst women aged 20-29 years to 53% amongst women aged 60-70 years. The proportion of American women with low desire displayed a trend towards an increase with age. In the 20-29 year age group 65% of European women and 67% of American women with low sexual desire were distressed by it. This decreased to 22% and 37%, respectively, in the 60-70 year age group. In Europe and the USA the prevalence of HSDD in the population did not change significantly with age (6-13% in Europe, 12-19% in the USA).
Conclusions: The proportion of women with low desire increased with age while the proportion of women distressed about their low desire decreased with age. Consequently, the prevalence of HSDD remained essentially constant with age. This may explain why no association between HSDD and age is often reported in the literature.

Short-term psychodynamic psychotherapy: review of recent process and outcome studies

Short-term psychodynamic psychotherapy (STPP) is a widely practised form of psychological intervention. Given that the Roth and Fonagy (1996) review concluded that there was a lack of confirming evidence for STPP, the current review is focused on studies published between 1996 and 2006 that evaluate the efficacy of STPP. As a result of a systematic literature review, 18 studies were found that met inclusion criteria consistent with those used by Roth and Fonagy (1996) for selection of studies, patient groupings and definition of therapeutic method. In general these studies add to an increasing body of evidence suggesting that STPP can be an effective psychological treatment for individuals experiencing mental health problems. Specifically, for depression STPP can be equal in effects to other psychological treatments and is significantly better than no treatment in the short term. Furthermore, emerging process data indicate that there is a significant relationship between the use of specific psychodynamic therapeutic techniques and the alleviation of depressive symptoms. Increasing evidence has emerged to support STPP as a treatment for generalized anxiety disorder, panic disorder and some personality disorders. There remains limited evidence for the use of STPP treatment for patients with anxiety disorders that relate more to stress. Very limited and inconclusive evidence currently exists to support STPP as a treatment for bipolar disorder, eating disorders and drug dependency. Future research needs to include broader assessment measures, long-term follow up, studies that maintain an identifiable focus, and research that includes a focus on psychotherapy process variables as they interact with outcomes.

Is phase-specific, community-oriented treatment of early psychosis- an economically viable method of improving outcome?

Objective: The Early Psychosis Prevention and Intervention Centre (EPPIC) provides a comprehensive 'real-world' model of early intervention to young people experiencing an emerging psychotic disorder. A prospective study has already provided evidence of improved clinical outcome at 12 months after entry. The present study examined whether the service was also cost-effective.

Method: A cost-effectiveness analysis compared EPPIC with its immediate precursor service, from the perspective of the government funding agency. Only direct costs were included.

Results: EPPIC proved to be more cost-effective. The weighted average cost per patient for the first 12 months was cheaper (by äD 7110 per patient), while treatment outcomes were superior. The savings were due to the marked reduction in in-patient costs outweighing substantial increases in the costs of community care.

Conclusion: These results, while encouraging in terms of the further development of integrated, phase-specific intervention programmes for early psychosis, are not conclusive, and further research is required.

Australian patient safety survey

The national telephone survey found that 6.5% of respondents reported experiencing a medical adverse event during the preceding 12 months. Most reported were medication incidents, with misdiagnosis or wrong treatment second most common. Predictors of adverse event reporting included health status, hospital admission, and length of time seeing regular doctor.

Patient recall of receiving lifestyle advice for overweight and hypertension from their general practitioner

Background
Overweight, obesity and hypertension can be prevented through improvements in lifestyle including nutrition and physical activity. General practitioners (GPs) in Australia have access to over 90% of the population in the course of a year and therefore, the general practice setting may be ideal to assist patients with lifestyle change for weight management and hypertension. The present study aimed to determine the proportion of overweight/obese patients that recalled receiving advice by their GP to make lifestyle changes for weight loss. Recall of advice received by hypertensive patients to reduce salt intake was also measured.

Methods
A face to face survey was conducted on a representative sample (urban, suburban and rural) of South Australian residents. Respondents provided information on height and weight (self-report), whether they had received lifestyle advice from their GP for weight loss, and for those with self reported hypertension if they had received advice to reduce dietary salt.

Results
The sample included 2947 South Australian adult residents (58% female; BMI (mean (SD)), 26.6 (5.3) kg/m2; age, 50.7 (18.0) years). Ninety-six percent had visited their GP in the past 12 months. Forty-one percent of males and 25% of females were overweight and 19% of males and 20% of females were obese. Twenty-seven percent of overweight/obese respondents reported receiving lifestyle advice for weight loss purposes. Of the 33% who reported they had hypertension, 34% reported receiving advice to reduce salt intake.

Conclusions
Less than 1/3 of overweight/obese patients reported that they had received lifestyle advice that could assist with weight loss from their GP. About a third of respondents with hypertension reported that they received advice to reduce salt intake. There are potentially missed opportunities in which GPs could provide re-enforcement of benefits of lifestyle changes with respect to weight and blood pressure control.

Evaluation of a community pharmacy-based intervention for improving patient adherence to antihypertensives: a randomised controlled trial

Background
The majority of patients using antihypertensive medications fail to achieve their recommended target blood pressure. Poor daily adherence with medication regimens and a lack of persistence with medication use are two of the major reasons for failure to reach target blood pressure. There is no single intervention to improve adherence with antihypertensives that is consistently effective. Community pharmacists are in an ideal position to promote adherence to chronic medications. This study aims to test a specific intervention package that could be integrated into the community pharmacy workflow to enable pharmacists to improve patient adherence and/or persistence with antihypertensive medications - Hypertension Adherence Program in Pharmacy (HAPPY).

Methods/Design
The HAPPY trial is a multi-centre prospective randomised controlled trial. Fifty-six pharmacies have been recruited from three Australian states. To identify potential patients, a software application (MedeMine CVD) extracted data from a community pharmacy dispensing software system (FRED Dispense®). The pharmacies have been randomised to either 'Pharmacist Care Group' (PCG) or 'Usual Care Group' (UCG). To check for 'Hawthorne effect' in the UCG, a third group of patients 'Hidden Control Group' (HCG) will be identified in the UCG pharmacies, which will be made known to the pharmacists at the end of six months. Each study group requires 182 patients. Data will be collected at baseline, three and six months in the PCG and at baseline and six months in the UCG. Changes in patient adherence and persistence at the end of six months will be measured using the self-reported Morisky score, the Tool for Adherence Behaviour Screening and medication refill data.

Discussion
To our knowledge, this is the first research testing a comprehensive package of evidence-based interventions that could be integrated into the community pharmacy workflow to enable pharmacists to improve patient adherence and/or persistence with antihypertensive medications. The unique features of the HAPPY trial include the use of MedeMine CVD to identify patients who could potentially benefit from the service, control for the 'Hawthorne effect' in the UCG and the offer of the intervention package at the end of six months to patients in the UCG, a strategy that is expected to improve retention.

Attitudes of mental health staff to routine outcome measurement

Background: Routine outcome measurement is mandated in public mental health services in Australia, but uptake and compliance are variable. This may be because of uncertainties and resistances among clinicians.
Aims: To survey attitudes and practices to routine outcome measurement among staff in adult area mental health services and to elucidate their correlates.
Method: As part of a larger study, a specifically designed questionnaire was distributed to all staff.
Results: A high return rate was achieved. A wide range of opinion was found. Staff who had attended training reported the measures as easier to use than those who had not. Staff who had recently seen feedback rated outcome measures as more valuable but less easy to use than those who had not seen feedback. Compared to other disciplines, medical staff and psychologists tended to rate outcome measures as less useful.
Conclusions: The results have implications for the implementation and sustainability of routine outcome measurement. They highlight the need for staff to receive targeted training and usable reports, and to have access to resources to extract meaning and value from outcome measures.

The Early Prevention of Obesity in CHildren (EPOCH) collaboration : an individual patient data prospective meta-analysis

Background
Efforts to prevent the development of overweight and obesity have increasingly focused early in the life course as we recognise that both metabolic and behavioural patterns are often established within the first few years of life. Randomised controlled trials (RCTs) of interventions are even more powerful when, with forethought, they are synthesised into an individual patient data (IPD) prospective meta-analysis (PMA). An IPD PMA is a unique research design where several trials are identified for inclusion in an analysis before any of the individual trial results become known and the data are provided for each randomised patient. This methodology minimises the publication and selection bias often associated with a retrospective meta-analysis by allowing hypotheses, analysis methods and selection criteria to be specified a priori.

Methods/Design
The Early Prevention of Obesity in CHildren (EPOCH) Collaboration was formed in 2009. The main objective of the EPOCH Collaboration is to determine if early intervention for childhood obesity impacts on body mass index (BMI) z scores at age 18-24 months. Additional research questions will focus on whether early intervention has an impact on children's dietary quality, TV viewing time, duration of breastfeeding and parenting styles. This protocol includes the hypotheses, inclusion criteria and outcome measures to be used in the IPD PMA. The sample size of the combined dataset at final outcome assessment (approximately 1800 infants) will allow greater precision when exploring differences in the effect of early intervention with respect to pre-specified participant- and intervention-level characteristics.

Discussion
Finalisation of the data collection procedures and analysis plans will be complete by the end of 2010. Data collection and analysis will occur during 2011-2012 and results should be available by 2013.

The 6-PACK programme to decrease fall-related injuries in acute hospitals: protocol for a cluster randomised controlled trial

Background and aims In-hospital fall-related injuries are a source of personal harm, preventable hospitalisation costs, and access block through increased length of stay. Despite increased fall prevention awareness and activity over the last decade, rates of reported fall-related fractures in hospitals appear not to have decreased. This cluster randomised controlled trial (RCT) aims to determine the efficacy of the 6-PACK programme for preventing fall-related injuries, and its generalisability to other acute hospitals.

Methods 24 acute medical and surgical wards from six to eight hospitals throughout Australia will be recruited for the study. Wards will be matched by type and fall-related injury rates, then randomly allocated to the 6-PACK intervention (12 wards) or usual care control group (12 wards). The 6-PACK programme includes a nine-item fall risk assessment and six nursing interventions: ‘falls alert’ sign; supervision of patients in the bathroom; ensuring patient’s walking aids are within reach; establishment of a toileting regime; use of a low-low bed; and use of bed/chair alarm. Intervention wards will be supported by a structured implementation strategy. The primary outcomes are fall and fall-related injury rates 12 months following 6-PACK implementation.

Discussion This study will involve approximately 16 000 patients, and as such is planned to be the largest hospital fall prevention RCT to be undertaken and the first to be powered for the important outcome of fall-related injuries. If effective, there is potential to implement the programme widely as part of daily patient care in acute hospital wards where fall-related injuries are a problem.

An audit of clinical outcomes and client and referrer satisfaction with a mood and anxiety Disorders unit

Objective To evaluate outcome and client and referrer satisfaction with the service provided by a Mood and Anxiety Disorders Unit (MADU).

Method MADU was a specialized clinical service for the assessment and management of individuals suffering with affective and anxiety disorders. Clients were referred to MADU from a variety of health service providers. A telephone survey of 30 clients and 20 referrers who have used the services of MADU was conducted, investigating outcome satisfaction with the service provided by MADU.

Results Clients and referrers reported a high level of satisfaction with the service provided by MADU. There was a high degree of adherence to treatment recommendations. The mean Patient Global Impression of Improvement (PGI) rating by the clients before the MADU assessment was 2.74 (SD = 1.27). In comparison the mean PGI rating at the time of follow-up was 6.64 (SD = 1.91).

Conclusions Specialist mood disorders units are a useful and potentially cost-effective additional service included as a part of a mental health service.

The validity of the 21-item version of the depression anxiety stress scales as a routine outcome measure

Objective: This study aimed to test the validity of the 21-item Depression Anxiety Stress Scales (DASS-21) as a routine clinical outcome measure in the private in-patient setting. We hypothesized that it would be a suitable routine outcome instrument in this setting.

Method: All in-patients treated at a private psychiatric hospital over a period of 24 months were included in the study. Data were collected on demographics, service utilization, diagnosis and a set of four routine measures both at admission and discharge. These measures consisted of the Clinical Global Impressions (CGI) scales, Health of the Nation Outcome Scales (HoNOS), the Mental Health Questionnaire (MHQ-14) and DASS-21. The results of these measures were compared.

Results: Of 786 admissions in total, the number of fully completed (ie paired admission and discharge) data sets for the DASS-21 depression, anxiety and stress subscales were 337, 328 and 347, respectively. All subscales showed statistically significant reductions in mean scores from admission to discharge (P < 0.001) and were significantly correlated with all MHQ-14 subscales and significantly related to CGI scale categories. The total DASS-21 and total HoNOS scores were also significantly correlated.

Conclusions: The findings from the present study support the validity of DASS-21 as a routine clinical outcome measure in the private in-patient setting.

Effectiveness of vertebroplasty using individual patient data from two randomised placebo controlled trials : meta-analysis

Objective To determine whether vertebroplasty is more effective than placebo for patients with pain of recent onset (≤6 weeks) or severe pain (score ≥8 on 0-10 numerical rating scale).

Design Meta-analysis of combined individual patient level data.

Setting Two multicentred randomised controlled trials of vertebroplasty; one based in Australia, the other in the United States.

Participants 209 participants (Australian trial n=78, US trial n=131) with at least one radiographically confirmed vertebral compression fracture. 57 (27%) participants had pain of recent onset (vertebroplasty n=25, placebo n=32) and 99 (47%) had severe pain at baseline (vertebroplasty n=50, placebo n=49).

Intervention Percutaneous vertebroplasty versus a placebo procedure.

Main outcome measure Scores for pain (0-10 scale) and function (modified, 23 item Roland-Morris disability questionnaire) at one month.

Results For participants with pain of recent onset, between group differences in mean change scores at one month for pain and disability were 0.1 (95% confidence interval −1.4 to 1.6) and 0.2 (−3.0 to 3.4), respectively. For participants with severe pain at baseline, between group differences for pain and disability scores at one month were 0.3 (−0.8 to 1.5) and 1.4 (−1.2 to 3.9), respectively. At one month those in the vertebroplasty group were more likely to be using opioids.

Conclusions Individual patient data meta-analysis from two blinded trials of vertebroplasty, powered for subgroup analyses, failed to show an advantage of vertebroplasty over placebo for participants with recent onset fracture or severe pain. These results do not support the hypothesis that selected subgroups would benefit from vertebroplasty.
