Preventing falls among older people : current practice and attitudes among community pharmacists

Objective: Falls among older people are a major cause of injury and death in Australia Urgent action is required if we are to stem the .epidemic' increase in falls as our population ages. This paper describes current practice and attitudes of community pharmacists in Northern Rivers, New South Wales, in relation to preventing falls. .. Method: Comm~typhannacists in the Northern Rivers area ofNew South Wales were surveyed to detennine their current activities to reduce the risk of falls in older clients and to gauge awareness of the successful 1992-96 falls prevention program- 'Stay on Your Feet'. Results: Response rate was 79% (53/67). Seventy-two per cent reported that they urge 'most' or 'almost all' older clients to bring in out-of-date medications for disposal, 66% give them falls prevention advice at least 'sometimes', 57% refer at least 'some' older clients to allied health practitioners for assessment or treatment of falls risk. and 92% are interested in receiving more written information regarding falls prevention. Conclusion: The fmdings suggest that while community pharmacists are both ready and keen to play a role in future falls prevention initiatives. their current involvement varies considerably. Specific ways in which they might further help to reduce falls are: regularly checking the potential of client. medications to connibute to falls. giving more verbal or written advice, promoting 'falls safe' products, referring older clients to allied health practitioners for assessment or treatment of falls risk, and training staff [Q provide falls prevention advice

Older adults' neuromuscular adaptations to resistence training and effects on challenging gait tasks

Community locomotion is threatened when older individuals are required to negotiate obstacles, which place considerable stress on the musculoskeletal system. The vulnerability of older adults during challenging locomotor tasks is further compromised by age-related strength decline and muscle atrophy. The first study in this investigation determined the relationship between the major muscle groups of the lower body and challenging locomotor tasks commonly found in the community environment of older adults. Twenty-nine females and sixteen males aged between 62 and 88 years old (68.2 ±6.5) were tested for the maximal voluntary contraction (MVC) strength of the knee extensors and 1-RM for the hip extensors, flexors, adductors, abductors, knee extensors and flexors and ankle plantar flexors. Temporal measurements of an obstacle course comprising four gait tasks set at three challenging levels were taken. The relationship between strength and the obstacle course dependent measures was explored using linear regression models. Significant associations (p≤0.05) between all the strength measures and the gait performances were found. The correlation values between strength and obstructed gait (r = 0.356-0.554) and the percentage of the variance explained by strength (R2 = 13%-31%), increased as a function of the challenging levels, especially for the stepping over and on and off conditions. While the difficulty of community older adults to negotiate obstacles cannot be attributed to a single causal pathway, the findings of the first study showed that strength is a critical requirement. That the magnitude of the association increased as a function of the challenging levels, suggests that interventions aimed at improving strength would potentially be effective in helping community older adults to negotiate environmental gait challenges. In view of the findings of the first study, a second investigation determined the effectiveness of a progressive resistance-training program on obstructed gait tasks measured under specific laboratory conditions and on an obstacle course mimicking a number of environmental challenges. The time courses of strength gains and neuromuscular mechanisms underpinning the exercise-induced strength improvements in community-dwelling older adults were also investigated. The obstructed gait conditions included stepping over an obstacle, on and off a raised surface, across an obstacle and foot targeting. Forty-three community-living adults with a mean age of 68 years (control =14 and experimental=29) completed a 24-week progressive resistance training program designed to improve strength and induce hypertrophy in the major muscles of the lower body. Specific laboratory gait kinetics and kinematics and temporal measures taken on the obstacle course were measured. Lean tissue mass and muscle activation of the lower body muscle groups were assessed. The MVC strength of the knee extensors and 1-RM of the hip extension, hip flexion, knee extension, knee flexion and ankle plantar flexion were measured. A 25% increase on the MVC of the knee extensors (p≤0.05) was reported in the training group. Gains ranging between 197% and 285% were recorded for the 1-RM exercises in the trained subjects with significant improvements found throughout the study (p≤0.05). The exercise-induced strength gains were mediated by hypertrophic and neural factors as shown by 8.7% and 27.7% increases (p≤0.05) in lean tissue mass and integrated electromyographic activity, respectively. Strength gains were accompanied by increases in crossing velocity, stride length and reductions in stride duration, stance and swing time for all gait tasks except for the foot targeting condition. Specific kinematic variables associated with safe obstacle traverse such as vertical obstacle heel clearance, limb flexion, horizontal foot placements prior to and at post obstacle crossing and landing velocities resulted in an improved crossing strategy in the experimental subjects. Significant increases in the vertical and anterior-posterior ground reaction forces accompanied the changes in the gait variables. While further long-term prospective studies of falls rates would be needed to confirm the benefits of lower limb enhanced strength, the findings of the present study provide conclusive evidence of significant improvements to gait efficiency associated with a systematic resistance-training program. It appears, however, that enhanced lower body strength has limited effects on gait tasks involving a dynamic balance component. In addition, due to the larger strength-induced increases in voluntary activation of the leg muscle compared to relatively smaller gains in lean tissue mass, neural adaptations appear to play a greater contributing role in explaining strength gains during the current resistance training protocol.

Quality of life and depression among older patients waiting for joint replacement surgery

Purpose: Older patients waiting for joint replacement surgery in many western countries experience lengthy waits for their surgery. Although these patients suffer with mobility problems the nature of the disability associated with waiting for surgery is unclear. The purpose of this study was to determine health-related quality of life and symptoms of depression in persons waiting for their initial orthopaedic consultation following referral for total knee or total hip replacement surgery.

Methods: All patients who were waiting for an initial orthopaedic consultation for lower-limb joint replacement as at 25 August 2005 were surveyed. Participants were mailed questionnaires concerning demographic information, medical history, health-related quality of life (the Assessment of Quality of Life (AQoL) instrument), and symptoms of depression (Center for Epidemiologic Studies – Depression (CES-D) Scale).

Results: The 84 respondents (response rate 64%) had a mean age of 68.3 (SD 11.5 years), and 60% or respondents were women. Respondents reported an average of 1.6 (SD 0.9) medical conditions, and 85% reported osteoarthritis.} The average health-related quality of life was low (mean AQoL 0.38; SD 0.27), and near death-equivalent or worse than death-equivalent health-related quality of life (AQoL<0.1 of a maximum possible 1.0) was reported by 23% of the participants.The mean depression scale score was 16.5 (SD 11.1), and symptoms of depression (CES-D>16 of a maximum possible 60) were reported by 35% of the sample. There was a strong correlation between health-related quality of life and depression (r=–0.6).

Conclusions: Almost a third of patients waiting to see an orthopaedic surgeon about joint replacement surgery for their hip or knee had symptoms of depression. Geriatric rehabilitation services often provide interventions to these patients. The very poor quality of life reported suggests that more than exercise and strengthening will be needed to reduce disability.

Biomechanics of gait determination in older adults

The majority of falls occur during routine ambulation and transfer tasks required for basic mobility such as rapid stopping. The study found that in comparison with young adults older adults more frequently used two steps to terminate walking. This is due to increased onset times in the rear leg muscles and a lower frequency of ankle and hip extensor recruitment in the front leg.

Extending double standards and stereotyping approaches to hiring older workers

This thesis examined factors underlying discrimination against older job applicants. Drawing upon stereotyping and double standards-based approaches to discrimination the thesis found that positive and negative aspects of the older worker stereotype can have cumulative effects on hiring decisions and may interact with job requirements to affect discrimination.

Interactive effects of exercise plus calcium-vitamin D3 on bone strength in older men

The findings from this 18-month, community-based study revealed that an exercise program involving strength training and jumping activities was feasible and effective for improving bone density, muscle mass and strength in older men. There were no additional skeletal benefits derived from consuming a high calcium-vitamin D milk drink.

Reducing adverse events in older Australians taking newly released drugs

The number of older Australians with one or multiple chronic diseases is increasing. This thesis presents a model to assist in identifying current older patients with multiple illnesses and taking multiple medications who are at risk of experiencing an adverse drug reaction if they are prescribed a newly released drug.

Investigations of access for people with disability and older people

The phenomenon of access was investigated in regard to people with disability and older people. Access is described as a journey which involves navigation of numerous access opportunities and barriers and achievement of an access goal. While differences existed, numerous access issues and solutions are relevant to the two groups.

Health-related beliefs, explanations and actions of older Anglo-Celtic-Australians

This thesis was an exploration of the health-related understandings and experiences of older Anglo-Celtic-Australians from a disadvantaged metropolitan locality. New insights were gained about the relationship between disadvantage and poor health outcomes; particularly the impact of limited self-care practices in combination with difficulties relating to the health care professionals.

Community nutrition : providing for older citizens

Diet quality is a contributing factor to the health of the increasing number of aged. A fortnightly small group meal program focusing on social interaction was trialled. It was concluded that the program had strong support from participants and that there is scope for expansions of existing food service programs to include alternative styles of presentations; and that the principle of the Community Meals Program should be continued and endorsed.

Passing time in Clifton Court : an ethnographic study of a unit for confused older people

An exploration of how the residents of a 30 bed unit for confused older people spent their time and a description of the impact upon this of any associated factors. The study demonstrates that it is possible for for elders with dementia and mental health problems to enjoy a range of activities, however, these need to be individualised to take into account the skills they have to meet the challenges with which they are presented. The informed contribution from the activities personnel and the support of nurses is vital to ensure a high quality of social interaction. Sound leadership at the clinical level is essential.

Illness representations and cancer screening in older women

This research investigated why some older women do not obtain screening mammograms and Pap smear tests. In-depth interviews found many beliefs which are contrary to screening and influenced the women's screening behaviour.

Older women and sternotomy

Explores the experiences of older women having a sternotomy incision following cardiac surgery. Older women account for a large proportion of patients undergoing cardiac surgery each year in Australia. The context from which they face cardiac surgery is unlike that of men and of younger women, and there has been limited exploration of their experiences.
