The reliability and predictive accuracy of the falls risk for older people in the community assessment (FROP-Com) tool

BACKGROUND the Falls Risk for Older People in the Community assessment (FROP-Com) tool was designed for use in targeted multi-factorial falls prevention programmes. It fills the gap between the short screening tools and the longer assessment tools, e.g. the physiological profile assessment (PPA). The aim of this study was to determine the reliability and predictive accuracy of the FROP-Com. METHODS the intra-rater and inter-rater reliability studies were performed with 20 participants each. The prospective study was performed with 344 community-dwelling older people presenting to an emergency department after a fall and being discharged directly home. Following a home-based assessment, including the FROP-Com, Timed Up and Go (TUG) and functional Reach (FR), participants were monitored for falls for 12 months. RESULTS the intra-class correlation coefficient (ICC) for intra-rater reliability and inter-rater reliability for the FROP-Com was 0.93 (95% CI 0.84-0.97) and 0.81 (95% CI 0.59-0.92) respectively. The AUC for the FROP-Com was 0.68 (95% CI 0.63-0.74). At the cut-off 18/19, sensitivity was 71.3% (95% CI 64.4-78.3) and specificity was 56.1% (95% CI 48.9-63.4). The AUC for the TUG was 0.63 (95% CI 0.57-0.69) and for the FR was 0.60 (95% CI 0.54-0.66). CONCLUSION the FROP-Com demonstrated good reliability and a moderate capacity to predict falls.

Development of the Falls Risk for Older People in the Community (FROP-Com) screening tool*

BACKGROUND the aim of this study was to develop a brief screening tool for use in the emergency department (ED), to identify people who require further assessment and management. METHODS this prospective study included 344 community-dwelling older people presenting to an ED after a fall. After direct discharge participants had a home-based assessment performed that included the Falls Risk for Older People in the Community (FROP-Com), a comprehensive, yet simple, multifactorial falls risk assessment tool. They were then monitored for falls for 12 months. The items from the FROP-Com assessment tool predictive of falls in a multifactorial logistic regression were used to develop the FROP-Com screen. RESULTS the items significantly predictive of falls and combined to form the FROP-Com screen were: falls in the previous 12 months, observation of the persons balance and the need for assistance to perform domestic activities of daily living. At the cut-off with the highest Youden index sensitivity was 67.1% (95% CI 59.9-74.3) and specificity was 66.7% (95% CI 59.8-73.6). CONCLUSION the FROP-Com screen has a relatively good capacity to predict falls. It can be used in time-limited situations to classify those at high risk of falls who require more detailed assessment and management.

Effectiveness of general practice based, practice nurse led telephone coaching on glycaemic control of type 2 diabetes: the Patient Engagement And Coaching for Health (PEACH) pragmatic cluster randomised controlled trial

Objective To evaluate the effectiveness of goal focused telephone coaching by practice nurses in improving glycaemic control in patients with type 2 diabetes in Australia. Design Prospective, cluster randomised controlled trial, with general practices as the unit of randomisation. Setting General practices in Victoria, Australia. Participants 59 of 69 general practices that agreed to participate recruited sufficient patients and were randomised. Of 829 patients with type 2 diabetes (glycated haemoglobin (HbA1c) >7.5% in the past 12 months) who were assessed for eligibility, 473 (236 from 30 intervention practices and 237 from 29 control practices) agreed to participate. Intervention Practice nurses from intervention practices received two days of training in a telephone coaching programme, which aimed to deliver eight telephone and one face to face coaching episodes per patient. Main outcome measures The primary end point was mean absolute change in HbA1c between baseline and 18 months in the intervention group compared with the control group. Results The intervention and control patients were similar at baseline. None of the practices dropped out over the study period; however, patient attrition rates were 5% in each group (11/236 and 11/237 in the intervention and control group, respectively). The median number of coaching sessions received by the 236 intervention patients was 3 (interquartile range 1-5), of which 25% (58/236) did not receive any coaching sessions. At 18 months’ follow-up the effect on glycaemic control did not differ significantly (mean difference 0.02, 95% confidence interval −0.20 to 0.24, P=0.84) between the intervention and control groups, adjusted for HbA1c measured at baseline and the clustering. Other biochemical and clinical outcomes were similar in both groups. Conclusions A practice nurse led telephone coaching intervention implemented in the real world primary care setting produced comparable outcomes to usual primary care in Australia. The addition of a goal focused coaching role onto the ongoing generalist role of a practice nurse without prescribing rights was found to be ineffective.

A Randomized Controlled Trial of a Multifactorial Falls Prevention Intervention for Older Fallers Presenting to Emergency Departments

OBJECTIVES: To investigate the effect of a referral‐based targeted multifactorial falls prevention intervention on the occurrence of recurrent falls and injuries in older people presenting to an emergency department (ED) after a fall and discharged directly home from the ED.

Fear of falling in older fallers presenting at emergency departments

AIM This paper is a report of an investigation of fear of falling in older people presenting to emergency departments after a fall. BACKGROUND Falls are a common and disabling cause of attendance at emergency departments. Fear of falling is an often unrecognized consequence of falls that affects older peoples function. METHODS Sub-analysis was conducted of a randomized trial of a falls prevention programme for people aged 60 years and older presenting to emergency departments after a fall. Data were collected between 2003 and 2006 with 712 participants recruited (mean age 75, 70% female). Baseline and 12-month measurements included fear of falling (Modified Falls Efficacy Scale), falls risk, depression, and balance/mobility measures. Intervention participants received interventions based on assessment findings, while control participants received usual care. Repeated measures analysis of variance and logistic regression were used to determine change over time between groups and factors associated with fear of falling, respectively. RESULTS Sixty per cent of participants had fear of falling. Statistically significant improvement occurred in overall fear of falling (repeated measures analysis of variance -F = 37.3; P < 0.001) and 13 of 14 sub-items of the Modified Falls Efficacy Scale at 12 months, but there was no difference between groups. Multivariate logistic regression identified a number of factors associated with statistically significant increased odds of higher fear of falling persisting at12 months, including higher baseline fear of falling and multiple falls in the 12-month follow-up. CONCLUSION Nursing staff in emergency departments have an important role in identifying fear of falling, which may guide the need for referral for further assessment and management after discharge from the emergency department.

Telemedicine interventions for gestational diabetes mellitus: A systematic review and meta-analysis

OBJECTIVE To evaluate the effect of telemedicine on GDM service and maternal, and foetal outcomes. METHODS A systematic review and meta-analysis of randomised controlled trials (RCT) of telemedicine interventions for GDM was conducted. We searched English publications from 01/01/1990 to 31/08/2013, with further new publication tracking to June 2015 on MEDLINE, EMBASE, PUBMED, CINAHL, the Cochrane Central Register of Controlled Trials and the World Health Organization International Clinical Trials Registry electronic databases. Findings are presented as standardised mean difference (SMD) and odds ratios (OR) or narrative and quantitative description of findings where meta-analysis was not possible. RESULTS Our search yielded 721 abstracts. Four met the inclusion criteria; two publications arose from the same study, resulting in three studies for review. All studies compared telemedicine to usual care. Telemedicine was associated with significantly fewer unscheduled GDM clinic visits, SMD. Quality of life, glycaemic control (HbA1c, pre and postprandial blood glucose level (BGL)), and caesarean section rate were similar between the telemedicine and usual care groups. None of the studies evaluated costs. CONCLUSIONS Telemedicine has the potential to streamline GDM service utilisation without compromising maternal and foetal outcomes. Its advantage may lie in the convenience of reducing face-to-face and unscheduled consultations. Studies are limited and more trials that include cost evaluation are required.

Quit in General Practice: a cluster randomised trial of enhanced in-practice support for smoking cessation

BackgroundThis study will test the uptake and effectiveness of a flexible package of smoking cessation support provided primarily by the practice nurse (PN) and tailored to meet the needs of a diversity of patients.Methods/DesignThis study is a cluster randomised trial, with practices allocated to one of three groups 1) Quit with Practice Nurse 2) Quitline referral 3) GP usual care. PNs from practices randomised to the intervention group will receive a training course in smoking cessation followed by access to mentoring. GPs from practices randomised to the Quitline referral group will receive information about the study and the process of written referral and GPs in the usual care group will receive information about the study. Eligible patients are those aged 18 and over presenting to their GP who are daily or weekly smokers and who are able to give informed consent. Patients on low incomes in all three groups will be able to access free nicotine patches.Primary outcomes are sustained abstinence and point prevalence abstinence at the three month and 12 month follow-up points; and incremental cost effectiveness ratios at 12 months. Process evaluation on the reach and acceptability of the intervention approached will be collected through Computer Assisted Telephone Interviews (CATI) with patients and semi-structured interviews with PNs and GPs.The primary analysis will be by intention to treat. Cessation outcomes will be compared between the three arms at three months and 12 month follow-up using multiple logistic regression. The incremental cost effectiveness ratios will be estimated for the 12 month quit rate for the intervention groups compared to usual care and to each other. Analysis of qualitative data on process outcomes will be based on thematic analysis.DiscussionHigh quality evidence on effectiveness of practice nurse interventions is needed to inform health policy on development of practice nurse roles. If effective, flexible support from the PN in partnership with the GP and the Quitline could become the preferred model for providing smoking cessation advice in Australian general practice.Trial RegistrationACTRN12609001040257

Quit in general practice: a cluster randomized trial of enhanced in-practice support for smoking cessation

OBJECTIVES To evaluate the uptake and effectiveness of tailored smoking cessation support, provided primarily by the practice nurse (PN), and compare this to other forms of cessation support. METHODS Three arm cluster randomized controlled trial conducted in 101 general practices in Sydney and Melbourne involving 2390 smokers. The Quit with PN intervention was compared to Quitline referral and a usual care control group. Smoking cessation pharmacotherapy was recommended to all groups. Outcomes were assessed by self-report at 3- and 12-month follow-up. Uptake of the interventions is also reported. RESULTS The three groups were similar at baseline. Follow-up at 12 months was 82%. The sustained and point prevalence abstinence rates, respectively, at 3 months by group were: PN intervention 13.1% and 16.3%; Quitline referral 10.8% and 14.2%; Usual GP care 11.4% and 15.0%. At 12 months, the rates were: PN intervention 5.4% and 17.1%; Quitline referral 4.4% and 18.8%; Usual GP care 2.9% and 16.4%. Only 43% of patients in the PN intervention group attended to see the nurse. Multilevel regression analysis showed no effect of the intervention overall, but patients who received partial or complete PN support were more likely to report sustained abstinence [partial support odds ratio (OR) 2.27; complete support OR 5.34]. CONCLUSION The results show no difference by group on intention to treat analysis. Those patients who received more intensive PN intervention were more likely to quit. This may have been related to patient motivation or an effect of PN led cessation support.

Roles and relationships between health professionals involved in insulin initiation for people with type 2 diabetes in the general practice setting: a qualitative study drawing on relational coordination theory

BackgroundThe majority of care for people with type 2 diabetes occurs in general practice, however when insulin initiation is required it often does not occur in this setting or in a timely manner and this may have implications for the development of complications. Increased insulin initiation in general practice is an important goal given the increasing prevalence of type 2 diabetes and a relative shortage of specialists. Coordination between primary and secondary care, and between medical and nursing personnel, may be important in achieving this. Relational coordination theory identifies key concepts that underpin effective interprofessional work: communication which is problem solving, timely, accurate and frequent and relationships between professional roles which are characterized by shared goals, shared knowledge and mutual respect. This study explores roles and relationships between health professionals involved in insulin initiation in order to gain an understanding of factors which may impact on this task being carried out in the general practice setting.Method21 general practitioners, practice nurses, diabetes nurse educators and physicians were purposively sampled to participate in a semi-structured interview. Transcripts of the interviews were analysed using framework analysis.ResultsThere were four closely interlinked themes identified which impacted on how health professionals worked together to initiate people with type 2 diabetes on insulin: 1. Ambiguous roles; 2. Uncertain competency and capacity; 3. Varying relationships and communication; and 4. Developing trust and respect.ConclusionsThis study has shown that insulin initiation is generally recognised as acceptable in general practice. The role of the DNE and practice nurse in this space and improved communication and relationships between health professionals across organisations and levels of care are factors which need to be addressed to support this clinical work. Relational coordination provides a useful framework for exploring these issues.

An exploratory trial of basal and prandial insulin initiation and titration for type 2 diabetes in primary care with adjunct retrospective continuous glucose monitoring: INITIATION study

AIMS To evaluate basal and prandial insulin initiation and titration in people with type 2 diabetes mellitus (T2DM) in primary care and to explore the feasibility of retrospective-continuous glucose monitoring (r-CGM) in guiding insulin dosing. The new model of care features General Practitioners (GPs) and Practice Nurses (PNs) working in an expanded role, with Credentialed Diabetes Educator - Registered Nurse (CDE-RN) support. METHODS Insulin-naïve T2DM patients (HbA1c >7.5% [>58 mmol/mol] despite maximal oral therapy) from 22 general practices in Victoria, Australia commenced insulin glargine, with glulisine added as required. Each was randomised to receive r-CGM or self-monitoring of blood glucose (SMBG). Glycaemic control (HbA1c) was benchmarked against specialist ambulatory patients referred for insulin initiation. RESULTS Ninety-two patients mean age (range) 59 (28-77) years; 40% female; mean (SD) diabetes duration 10.5 (6.1) years participated. HbA1c decreased from (median (IQR)) 9.9 (8.8, 11.2)%; 85 (73, 99) mmol/mol to 7.3 (6.9, 7.8)%; 56 (52, 62) mmol/mol at 24 weeks (p < 0.0001). Comparing r-CGM (n = 46) with SMBG (n = 42), there were no differences in major hypoglycaemia (p=0.17) or ΔHbA1c (p = 0.31). More r-CGM than SMBG participants commenced glulisine (26/48 vs. 7/44; p < 0.001). Results were comparable to 82 benchmark patients, with similar low rates of major hypoglycaemia (2/89 vs. 0/82; p = 0.17) and less loss to follow up in the INITIATION group (3/92 vs. 14/82; p = 0.002). CONCLUSIONS Insulin initiation and titration for T2DM patients in primary care was safe and improved HbA1c with low rates of major hypoglycaemia. CDE-RNs were effective in a new consultant role. r-CGM use in primary care was feasible and enhanced post-prandial hyperglycaemia recognition. Trial registration ACTRN12610000797077.
