An Evaluation of the Greater Glasgow & Clyde Osteoporosis and Falls Strategy Dr Dawn Skelton & Fiona Neil, School of Health
The Process Jan 2008, Fiona Neil, OT within the Falls Service, was seconded to the GCAL 0.5 FTE for one year. Visits to representatives of all parts of the service (Jan 2008-Aug 2008) –Record current Protocols and Processes –Discuss and gather previous audits –Discuss potential data collection –Advise on relevant up to date guidelines/evidence base Any previously gathered audit or outcome information (for presentations at conferences etc) was collected as well as raw data where possible. Data blinded by the relevant service, permission sought from the Caldicott Guardian for NHSGGC. Some small audit projects and 2 Masters Project (GCU OT & PT student, with full NHS ethical approval)

Strength & Balance Programmes Evidence based exercises –(Skelton 2005; Robertson 2001; Campbell 1999) Evidence based “deliverers” –Physiotherapists and trained Postural Stability Instructors (Skelton 2004) Evidence based duration –Dose of 50 hours of balance challenging exercise (Sherrington 2008)
Attendance at classes
Evaluation of effect N= 274 clients considered over a time period in Attended on average 11.9 (sd 3.8) weeks Outcome measures: –Duration of attendance –Functional tests Tinetti Mobility and Balance Score Timed Up and Go 180 degree turn Functional Reach Confidence in Maintaining Balance Tinetti’s Falls Efficacy Scale (FES) –Patient Satisfaction Questionnaires (N=91) Same assessor throughout - not all tests completed on all clients
Outcome measures Test Mean (sd) Number of clients Before exercise sessions After exercise sessions P-value Tinetti Balance Score (3.3)24.8 (3.1) deg turn (deg) (1.9)5.0 (1.6)0.000 Functional Reach (cm) (5.9)20.9 (6.9)0.000 TUAG (sec) (6.7)16.3 (5.9)0.000 ConFBal (3.9)16.9 (3.4)0.000 Tinetti FES (16.5)21.5 (11.6)0.0002
Balance improvements are duration dependent The Tinetti Mobility and Balance Score showed considerable improvement, but the change was dependent on duration of exercise attendance. Those attendees that drop out of sessions before 12 weeks are unlikely to see clinically significant changes in their balance. This is in line with the recent systematic review of exercise (Sherrington et al. 2008) where a dose of at less than 50 hours confers little benefit to fall risk reduction.
Client Satisfaction Satisfaction forms at week 10 of their exercise programme (n=117 issued). 91 patients returned the forms (response rate 78%). 85% had received information about the class before the sessions started and most (83%) found the pre-class information useful. Only 1% thought the class was not in a suitable location; the staffs were not helpful; the exercises were rushed, too short or not well explained (showing a high degree of satisfaction with facilities and delivery). 98% felt the exercise classes were beneficial and 94% thought the sessions were good or very good. Open response questions showed good improvements to wellbeing (see next slide) however, many people just wrote “enjoyed” in this section!
Open responses to feedback
Summary The CFPP exercise service to prevent falls in Glasgow does improve many of the known risk factors for falls The benefits are duration dependent –clients should be encouraged to adhere for at least 12 weeks, ideally to the maximum 18 weeks and then to move into normal community exercise sessions for older people to maintain the improvements High degree of client satisfaction (though questionnaire could have been designed better)
WHAT ARE THE EFFECTS OF THE GGC FALLS EXERCISE SESSIONS ON FEAR OF FALLING, BALANCE CONFIDENCE AND QUALITY OF LIFE IN GLASWEGIAN FALLERS? Gaynor McGrath MSc Rehabilitation Science Glasgow Caledonian University Submitted Oct 2009
Aims and Methods Objectives: To examine whether a 12 week strength and balance exercise class improved an individual’s perception of their fear of falling, balance confidence and quality of life and whether there was an inter-relationship between outcome measures pre and post the exercise intervention. Methods: Prospective cohort study. Participants: Female fallers (n=13) aged >=65 years Questionnaires specific to fear of falling (SFES-I), balance confidence (CONFbal) and quality of life (SF-12) were completed prior to and on completion of the 12 week exercise intervention.
Results and Conclusion Results: following completion of the 12 week exercise intervention there was a significant reduction in fear of falling (p<0.05) together with a significant improvement in balance confidence (p<0.05) and quality of life (p<0.05). However, the only significant inter-relationship between outcome measures was between fear of falling and balance confidence post exercise intervention (p<0.05). Conclusion: An exercise intervention is effective in reducing fear of falling whilst improving balance confidence and quality of life in community dwelling older females 65 years and older. It also improves the inter- relationship between fear of falling and balance confidence post intervention.
WHAT ARE OLDER PEOPLE’S VIEWS ON THEIR FORTHCOMING TRANSITION BETWEEN THE PHYSIOTHERAPY-LED FALLS PREVENTION EXERCISE CLASS AND THE INSTRUCTOR-LED FALLS PREVENTION EXERCISE CLASS? Aisling O’Connor MSc Rehabilitation Science Glasgow Caledonian University 31st January 2009
Falls Intervention Programme GG & C – tiered exercise programme: Physiotherapist-led community class (12-18 weeks) Postural Stability Instructor (PSI)-led class Benefits of Falls Prevention Exercise Programmes (Hauer et al., 2003; Skelton et al., 1995; Narici et al., 2004; Mazzeo & Tanaka, 2001) Exercise intervention greater than 6 months in duration is necessary (Skelton, 2007). PSI-led class: low uptake & high drop-out rates
Aims Explore older people’s views on falls exercise classes Transition from physiotherapist-led classes to PSI-led classes Motivators & Barriers to the uptake and adherence Increase attendance rates at PSI-led classes
Methods – Qualitative Research Design: Principles of grounded theory. Sample: 5 participants from physiotherapist-led class (saturation point reached) Recruitment: Visit by researcher to classes Data Collection: Semi-structured interviews: 7 open questions Analysis of data: Transcription of interviews -Open coding >> axial coding >> selective coding (+ memo writing)
Findings MOTIVATORS Benefits of Exercise (physical & psychological) Desire to Improve Social Interaction Confidence in Class Set-Up BARRIERS Knowledge of PSI-led Class Low Self Efficacy Low Outcome Expectations
New themes.…Motivator CONFIDENCE IN CLASS SET-UP -Not previously discussed in the literature -“...But I mean these people, whether it ’ s this class or the next advanced class, presumably they are experts in their own field. ” (P4, pg.10, L )
New themes….Barrier KNOWLEDGE OF PSI-LED CLASS Not previously discussed in the literature “…What’s this other class?” (P1, pg.1, L5-6) “...What time would it be? ” (P2, pg.3, L109) “...Where would I have to go in the first place? ” (P5, pg.11, L419)
Clinical Implications Lack of knowledge of PSI-led classes Increase awareness of Falls Prevention Services - booklet? - DVD? - reinforce information every week? Essential if attendance rates at PSI-led classes are to be increased and the risk of falling reduced
Future Research… …on the transition between classes with larger sample sizes & bigger geographical area …strategies to encourage older people with low self efficacy But most importantly… Effective strategy to inform older people of their options within Falls Prevention Programmes urgently needed!
How useful is the fracture Risk Assessment Tool (FRAX) in a falls clinic population? McCarthy C, Skelton DA, Gallacher S, Mitchell LE Abstract presented at 10 th National Conference on Postural Stability and Falls, Blackpool, 07/09/09
So what about case finding for bone fragility? Used to determine 10 year fracture risk in community dwelling adults – then NOGG suggests guidance on treatment
NOGG Advice based on FRAX
Research Questions What are the implications of using FRAX / NOGG in a falls clinic Setting? Can they identify those patients who would benefit from BMD assessment? Can they be used to determine treatment without the use of DEXA?
Methods 44 consecutive patients (33 F) attending a falls clinic –Mean age 78.0 (sd 6.0) years BMD measured –Lunar Prodigy, L2-L4 and neck of femur FRAX and NOGG assessed Statistics –Sensitivity, specificity, negative predictive values, positive predictive value, false negative and false positive rate for each FRAX cut off and NOGG advice to treat or not – before and after BMD measurement
Demographic Results After DEXA –Total 29.5% (n=13) had Osteoporosis (T < -2.5) –4 at hip and spine, 1 at spine alone, 8 at hip alone –A further 47% (n=21) had Osteopenia at spine and/or hip (T < -1) MeanSt Dev Tinetti (score) TUG (sec) FRAX score major OP (%) FRAX score hip (%) BMD at Spine BMD at hip
Results pre-DEXA NOGG advice (DEXA or treat) followed: –46% (n=6) of those with OP at either spine and/or hip would not be treated or advised a DEXA –Of those where DEXA was advised (n=18), 72% did not have osteoporosis (n=13) –Treatment advised in 2 patients both of whom had osteoporosis on subsequent DEXA
FRAX and NOGG not good in falls clinic at predicting need for DEXA and treatment Pre-FRAX NOGG Advice Sensitivity % Specificity % NPV % PPV % FP % FN % DXA advised and has OP DXA advised and has OP or OS
