The prevalence of foot problems in older women: a cause for concern

BACKGROUND: Painful feet are an extremely common problem amongst older women. Such problems increase the risk of falls and hamper mobility. The aetiology of painful and deformed feet is poorly understood. METHODS: Data were obtained during a pilot case-control study about past high heel usage in women, in relation to osteoarthritis of the knee. A total of 127 women aged 50-70 were interviewed (31 cases, 96 controls); case-control sets were matched for age. The following information was obtained about footwear: (1) age when first wore shoes with heels 1, 2 and 3 inches high; (2) height of heels worn for work; (3) maximum height of heels worn regularly for work, going out socially and for dancing, in 10-year age bands. Information about work-related activities and lifetime occupational history was gathered using a Life-Grid. The interview included a foot inspection. RESULTS: Foot problems, particularly foot arthritis, affected considerably more cases than controls (45 per cent versus 16 per cent, p = 0.001) and was considered a confounder. Cases were therefore excluded from subsequent analyses. Amongst controls, the prevalence of any foot problems was very high (83 per cent). All women had regularly worn one inch heels and few (8 per cent) had never worn 2 inch heels. Foot problems were significantly associated with a history of wearing relatively lower heels. Few work activities were related to foot problems; regular lifting was associated with foot pain (p = 0.03). CONCLUSION: Most women in this age-group have been exposed to high-heeled shoes over many years, making aetiological research difficult in this area. Foot pain and deformities are widespread. The relationship between footwear, occupational activities and foot problems is a complex one that deserves considerably more research.     

90—150型作训鞋预防足踝部军训伤的交叉对照人群试验

为进一步评价90-150型作训鞋预防足踝部军训伤的效果,1991年6月～7月,在某步兵团的8个连队战士中进行了交叉对照人群试验.以班序之奇偶分为甲乙2个人群组,分两个观察阶段进行.每阶段3周,间隔2周.观察阶段内实施强化训练,第一阶段甲组穿作训鞋(试穿组),乙组穿解放鞋(对照组),第二阶段互换.结果表明足踝部损伤的发生率:第一阶段试穿组为2.9%,对照组为14.3%;第二阶段试穿组为6.2%,对照组为16.6%;合计试穿组为4.5%,对照组为15.4%.无论从研究人群总体,人群组或是从不同阶段都发现试穿组与对照组的伤率相差非常显著,作训鞋使足踝部损伤的发生率减少了70.8%(56.6%～82.5%).本试验各种偏倚得到了有效控制,效果肯定,结论可靠.     

Does calcium supplementation prevent bone stress injuries? A clinical trial.

This study investigated the effect of calcium supplementation in preventing bone stress injuries. Healthy male military recruits (N = 1,398) served as subjects, of which 247 were randomly allocated to an experimental group (E) while 1,151 served as a control group (C). For 9 weeks both groups wore the same footwear and had the same physical training program. The baseline dietary intake of calcium in 50 randomly selected subjects of each group was assessed using a 24-hr dietary record. The E group received a daily calcium supplement while the C group did not. Injuries were monitored in all subjects by a panel of doctors who followed specific diagnostic criteria. The mean weekly injury incidence for all overuse injuries, but specifically tibial stress syndrome and stress fractures, was similar in both groups. Mean baseline daily dietary calcium intake was above 800 mg in both subgroups. This study demonstrated that large-scale calcium supplementation (500 mg/day) beyond usual dietary intake did not influence the risk of developing bone stress injuries during a 9-wk physical training program in these young military recruits.     

Footwear modification following hallux valgus surgery: The all-or-none phenomenon

AIM: To define footwear outcomes following hallux valgus surgery, focusing on patient return to comfortable and heeled footwear and patterns of post-operative footwear selection. METHODS: Surgical intervention is indicated for symptomatic cases of hallux valgus unresponsive to conservative methods, with favourable reported outcomes. The return to various types of footwear post-operatively is reflective of the degree of correction achieved, and corresponds to patient satisfaction. Patients are expected to return to comfortable footwear post-operatively without significant residual symptoms. Many female patients will additionally attempt to return to high-heeled, narrow toe box shoes. However, minimal evidence exists to guide their expectations. Sixty-five female hallux valgus patients that had undergone primary surgery between 2011 and 2013 were retrospectively identified using our hospital surgical database. Patients were reviewed using a footwear-specific outcome questionnaire at a mean 18.5 mo follow-up. RESULTS: Eighty-six percent of patients were able to return to comfortable footwear post-operatively with minimal discomfort. Of those intending to resume wearing heeled footwear, 62% were able to do so, with 77% of these patients wearing these as or more frequently than pre-operatively. No significant difference was observed between pre- and post-operative heel size. Mean time to return to heeled footwear was 21.4 wk post-operation. Cosmetic outcomes were very high and did not adversely impact footwear selection. CONCLUSION: We report high rates of return to both comfortable and heeled shoes in female patients following primary hallux valgus surgery. We observed an “all-or-none phenomenon” where patients rejected a return to heeled footwear unless able to tolerate them at the same frequency and heel size as pre-operatively. A minority of patients were unable to return to comfortable footwear post-operatively, which had adverse ramifications on their quality-of-life. We recommend that the importance of managing patient expectations through appropriate pre-operative counselling be emphasized in forefoot surgery.     

Medical costs of fourteen occupational illnesses in the United States in 1999

OBJECTIVES: This study estimated the annual medical costs associated with 14 occupational illnesses in the United States in 1999. METHODS: National data sets collected by the National Center for Health Statistics, the Health Care Financing Administration, and the Agency for Healthcare Research and Quality were aggregated and analyzed. The cost assessment began with estimates of national health expenditures. These included categories for hospital care, professional services, nursing homes, and medical products, including drugs, administration, public health activities, research and construction. The total disease burden was assessed from estimates of hospital days and number of outpatient visits. The occupational disease burden was assessed by multiplying the total disease burden by a given percentage of the proportionate attributable risk for the disease in question. The occupational burden was then combined with costs for each disease. Adjustments were made for unique inpatient and outpatient costs. RESULTS: In the preferred model, the 14 diseases generated USD 14.5 billion in medical costs in 1999. Roughly USD 10.7 billion was attributed to men and USD 3.8 billion to women. The diseases generating the most costs were as follows: circulatory diseases in the age group 24-64 years (USD 4.7 billion), cancer (USD 4.3 billion), chronic obstructive pulmonary disease (USD 2.2 billion), and asthma (USD 1.5 billion). A sensitivity analysis generated alternative estimates. An upper age limit of 74 years increased the circulatory disease estimate by USD 3.7 billion. The range of the sensitivity analysis was USD 9.6-19.7 billion. CONCLUSION: This study significantly improves over the methodology of previous literature. Our methods were transparent. Occupational illnesses were a major contributor to the total cost of medical care.     

Overuse injury syndromes of the locomotor system

Related either to athletic activities and recreation or to various professional activities, overuse injuries of the musculoskeletal system are common in the life of modern humans. Various studies indicate that approximately 30% to 50% of all sports injuries are caused by overuse. Therefore, it is not surprising that overuse injuries are frequently discussed. The mode of this discussion is usually limited to the analysis of different individual painful syndromes, specific localization of the painful syndrome in the musculoskeletal system, or the specific tissues affected by overuse injuries (tendinitis, bursitis, stress fractures, etc.). The purpose of this article is to systematically present today's knowledge of overuse injuries which affect the musculoskeletal system as a whole. Regardless of the localisation and the affected tissue, all clinical entities are presented in the same manner: the name and the definition of the syndrome, aetiopathogenesis, clinical picture, diagnostic, non operative, and surgical treatment, and the possibility of prevention. Beside presenting the newest discoveries reported in medical literature, this article also brings a wealth of individual cases and experiences encompassing histopathological examination, x-ray analysis, and the results of both conservative and surgical procedures.

Economic evaluation of a community based exercise programme to prevent falls

OBJECTIVE: To assess the incremental costs and cost effectiveness of implementing a home based muscle strengthening and balance retraining programme that reduced falls and injuries in older women. DESIGN: An economic evaluation carried out within a randomised controlled trial with two years of follow up. Participants were individually prescribed an exercise programme (exercise group, n=116) or received usual care and social visits (control group, n=117). SETTING: 17 general practices in Dunedin, New Zealand. PARTICIPANTS: Women aged 80 years and older living in the community and invited by their general practitioner to take part. MAIN OUTCOME MEASURES: Number of falls and injuries related to falls, costs of implementing the intervention, healthcare service costs resulting from falls and total healthcare service costs during the trial. Cost effectiveness was measured as the incremental cost of implementing the exercise programme per fall event prevented. MAIN RESULTS: 27% of total hospital costs during the trial were related to falls. However, there were no significant differences in health service costs between the two groups. Implementing the exercise programme for one and two years respectively cost $314 and $265 (1995 New Zealand dollars) per fall prevented, and $457 and $426 per fall resulting in a moderate or serious injury prevented. CONCLUSIONS: The costs resulting from falls make up a substantial proportion of the hospital costs for older people. Despite a reduction in falls as a result of this home exercise programme there was no significant reduction in healthcare costs. However, the results reported will provide information on the cost effectiveness of the programme for those making decisions on falls prevention strategies.     

Incidence and costs of injuries in The Netherlands

BACKGROUND: Injuries are a major and persistent public health problem, but a comprehensive and detailed overview of the economic burden is missing. We therefore estimated the number of emergency department (ED) attendances and health care costs as a result of injury. METHODS: We estimated lifetime health care costs of injuries occurring in The Netherlands in the year 1999. Patient groups were defined that are homogeneous in terms of health service use. Health service use and costs per patient group was estimated with data from national databases and a prospective study among 5755 injury patients. RESULTS: Total health care costs due to injury in 1999 were euro 1.15 billion, or 3.7% of the total health care budget. Major cost peaks were observed among males between ages 15 and 44 due to a high incidence, and among females from age 65 onwards due to a high incidence and high costs per patient. For the age groups 0-14, 15-44, 45-64, and 65+ ED attendances per 1000 person years were 85, 85, 43, and 49, respectively, and costs per capita were euro 38, euro 59, euro 43, and euro 210, respectively. Costs per patient rise about linearly up to age 60 and about exponentially thereafter. From age 25 onwards, females have higher costs per patient than males. Hip fracture (20%), superficial injury (13%), open wounds (7%), and skull-brain injury (6%) had the highest total costs. Most costs were attributable to falls (44%) and traffic injuries (19%). CONCLUSION: Young adult males, elderly females, falls, hip fractures, and minor injuries without medical need for hospitalization account for a substantial share of health care costs.     

Economic analysis of a school-based obesity prevention program

OBJECTIVE: To assess the cost-effectiveness and cost-benefit of Planet Health, a school-based intervention designed to reduce obesity in youth of middle-school age children. RESEARCH METHODS AND PROCEDURES: Standard cost-effectiveness analysis methods and a societal perspective were used in this study. Three categories of costs were measured: intervention costs, medical care costs associated with adulthood overweight, and costs of productivity loss associated with adulthood overweight. Health outcome was measured as cases of adulthood overweight prevented and quality-adjusted life years (QALYs) saved. Cost-effectiveness ratio was measured as the ratio of net intervention costs to the total number of QALYs saved, and net-benefit was measured as costs averted by the intervention minus program costs. RESULTS: Under base-case assumptions, at an intervention cost of $33,677 or $14 US dollars per student per year, the program would prevent an estimated 1.9% of the female students (5.8 of 310) from becoming overweight adults. As a result, an estimated 4.1 QALYs would be saved by the program, and society could expect to save an estimated $15,887 USD in medical care costs and $25,104 USD in loss of productivity costs. These findings translated to a cost of $4305 USD per QALY saved and a net saving of $7313 USD to society. Results remained cost-effective under all scenarios considered and remained cost-saving under most scenarios. DISCUSSION: The Planet Health program is cost-effective and cost-saving as implemented. School-based prevention programs of this type are likely to be cost-effective uses of public funds and warrant careful consideration by policy makers and program planners.     

Direct and indirect costs of home healthcare in Japan: A cross‐sectional study

To tackle the rising healthcare expenditure in an ageing society in Japan, home healthcare has been promoted over the past several years. However, there is a dearth of literature on total costs incurring for home healthcare. In this study, we conducted a cross‐sectional study among patients, who received home healthcare in the month of May, 2018. Direct healthcare costs and patients’ clinical characteristics were collected from medical records and long‐term care databases (n = 166). Indirect costs were estimated using a questionnaire survey which obtained information on job absenteeism and care time from the caregiver. A total of 112 patients responded to the survey. The median age was 82 years (interquartile range: 74–88). Total per‐person per month home‐care costs averaged USD 6,163 with direct costs (USD 2,547) and indirect costs (USD 3,596) accounted for 41.3% and 58.3% of the total costs, respectively. The largest components of direct costs were long‐term care costs (48%) and medical costs (47%). Multivariable adjusted model showed that those with heavy healthcare were more likely to incur higher total as well as direct and indirect home healthcare cost (p<.05 for each). Patients aged >75 years (p = .041) were less likely and those who used oxygen at home were more likely to incur direct home healthcare cost (p = .001) than their counterpart. Our study findings show that indirect cost is a major contributor to total home healthcare costs in Japan. Also for patients who need heavy healthcare, both direct and indirect costs are large burden.     

Model-Based Evaluation of Diabetic Foot Prevention Strategies in Austria

Diabetes mellitus affects approximately 171 million individuals worldwide. The costs of the adult form of diabetic mellitus account for up to 6% of total health care expenditures in industrialized countries. About 25% of these diabetics develop disabling and most painful foot complications accounting for about 17% of the direct lifetime costs. Diabetic foot prevention programs have been recently introduced in some Austrian federal states to meet the diabetic health targets of the Austrian Health Plan and the St. Vincent Declaration. We developed a new age-group specific Markov model combined with a Monte Carlo simulation model to help policymakers analyze the cost-effectiveness of such programs compared to the status quo in terms of incremental costs per quality-adjusted life years gained (QALY). The Markov model revealed that diabetic foot prevention programs were cost saving when targeted at patients at high risk and mainly cost-effective when targeted at patients with mild symptoms. The Monte Carlo simulation showed that only large scope prevention programs would fulfill the specified reductions in the number of diabetic foot complications as defined in the Austrian Health Plan and the St. Vincent Declaration. Our results clearly indicate the enormous impact of diabetic foot prevention programs.     

Economic burden of occupational injury and illness in the United States

Context: The allocation of scarce health care resources requires a knowledge of disease costs. Whereas many studies of a variety of diseases are available, few focus on job‐related injuries and illnesses. This article provides estimates of the national costs of occupational injury and illness among civilians in the United States for 2007. Methods: This study provides estimates of both the incidence of fatal and nonfatal injuries and nonfatal illnesses and the prevalence of fatal diseases as well as both medical and indirect (productivity) costs. To generate the estimates, I combined primary and secondary data sources with parameters from the literature and model assumptions. My primary sources were injury, disease, employment, and inflation data from the U.S. Bureau of Labor Statistics (BLS) and the Centers for Disease Control and Prevention (CDC) as well as costs data from the National Council on Compensation Insurance and the Healthcare Cost and Utilization Project. My secondary sources were the National Academy of Social Insurance, literature estimates of Attributable Fractions (AF) of diseases with occupational components, and national estimates for all health care costs. Critical model assumptions were applied to the underreporting of injuries, wage‐replacement rates, and AFs. Total costs were calculated by multiplying the number of cases by the average cost per case. A sensitivity analysis tested for the effects of the most consequential assumptions. Numerous improvements over earlier studies included reliance on BLS data for government workers and ten specific cancer sites rather than only one broad cancer category. Findings: The number of fatal and nonfatal injuries in 2007 was estimated to be more than 5,600 and almost 8,559,000, respectively, at a cost of $6 billion and $186 billion. The number of fatal and nonfatal illnesses was estimated at more than 53,000 and nearly 427,000, respectively, with cost estimates of $46 billion and $12 billion. For injuries and diseases combined, medical cost estimates were $67 billion (27% of the total), and indirect costs were almost $183 billion (73%). Injuries comprised 77 percent of the total, and diseases accounted for 23 percent. The total estimated costs were approximately $250 billion, compared with the inflation‐adjusted cost of $217 billion for 1992. Conclusions: The medical and indirect costs of occupational injuries and illnesses are sizable, at least as large as the cost of cancer. Workers’ compensation covers less than 25 percent of these costs, so all members of society share the burden. The contributions of job‐related injuries and illnesses to the overall cost of medical care and ill health are greater than generally assumed.     

Relation between health status of female assemblers and the degree of occupational fatigue]

Fatigue, the functional status and morbidity of women-assemblers of the watches and shoes have been investigated. Assessment of fatigue was based on the subjective parameters. Reliable changes in morbidity were not observed in women of 20-30 years of age with a high degree of fatigue, while in the group of women of 31-40 years of age an increase in the frequency of diseases of cardio-vascular, bone-muscular and peripheral nervous systems were observed. Correlation coefficients of the degree of fatigue were 0.42 for the frequency, and 0.37 for the number of days of staying at home due to the loss of the working ability. In the group of women of 41-50 years of age this correlation is less expressed, though the morbidity level is high. The leading factors of fatigue and morbidity in these professional groups are as follows: volume and intensity of work, visual stress and low-mobility position.     

One pair must last a lifetime. Case studies of foot care in diabetes

Neuropathy is the second most important of the four major 'traffic light' warnings for future foot problems (vascular, neuropathy, structural, self care). Peripheral neuropathy is a significant clinical problem in 20% of patients with diabetes. Painful neuropathy can disrupt patients lives but simple effective interventions are available. Painless neuropathy is often not perceived to be a problem by the patient or their doctor but puts the foot at risk from trauma (physical, chemical and thermal). Patients with neuropathy need systematic reassessment of self and professional diabetes care, and education about footwear and foot care. A podiatrist can be invaluable in prescribing appropriate footwear and orthotics to distribute foot pressure and in educating patients about self care. Patients with the 'double whammy' of neuropathy and vascular disease are at extreme risk of limb threatening problems and should have a regular monitoring program by themselves (or their carers) and their professionals as well as an 'action plan' to detect and deal with problems early.     

Controlling healthcare costs by removing waste: what American doctors can do now

Healthcare costs are unsustainable. The authors propose a solution to control costs without rationing (deliberate withholding of effective care) or payment reductions to doctors and hospitals. Three physician-led strategies comprise this solution: reduce (1) overuse of health services, (2) preventable complications and (3) waste within healthcare processes. These challenges know no borders.     

Characteristics of fallers who fracture at the foot, distal forearm, proximal humerus, pelvis, and shaft of the tibia/fibula compared with fallers who do not fracture

This case-control study examined the relation of circumstances of falls and characteristics of fallers with risk of fractures at five sites among persons 45 years of age or older from five Kaiser Permanente Medical Centers in Northern California from 1996 to 2001. Included were distal forearm (n = 1,016), foot (n = 574), proximal humerus (n = 467), pelvis (n = 150), and shaft of the tibia/fibula (n = 141) cases who fell at the time of their fracture, and controls (n = 512) who reported falling in the year before the interview but did not fracture. Interviewers collected information by using a standardized questionnaire. Medium-/high-heeled shoes and shoes with a narrow heel increased the risk of all fractures, and slip-on shoes (adjusted odds ratio = 2.3, 95% confidence interval: 1.4, 4.0) and sandals (adjusted odds ratio = 3.1, 95% confidence interval: 1.5, 6.3) increased the risk of foot fractures. Falling from more than a standing height increased the risk of all fractures by two- to fivefold, while breaking the fall was associated with lower risks of all fractures except the distal forearm. Physical activity and hormone therapy were associated with lower risks of most fractures. These results suggest ways in which risks of fractures in older persons can be reduced.     

Comparing cost effects of two quality strategies to improve test ordering in primary care: a randomized trial.

OBJECTIVE: To determine the costs and cost reductions of an innovative strategy aimed at improving test ordering routines of primary care physicians, compared with a traditional strategy. DESIGN: Multicenter randomized controlled trial with randomization at the local primary care physicians group level. SETTING: Primary care: local primary care physicians groups in five regions of the Netherlands with diagnostic centers. STUDY PARTICIPANTS: Twenty-seven existing local primary care physicians groups, including 194 primary care physicians. INTERVENTION: The test ordering strategy was developed systematically, and combined feedback, education on guidelines, and quality improvement sessions in small groups. In regular quality meetings in local groups, primary care physicians discussed each others' test ordering behavior, related it to guidelines, and made individual and/or group plans for change. Thirteen groups engaged in the entire strategy (complete intervention arm), while 14 groups received feedback only (feedback arm). MAIN OUTCOME MEASURE: Running costs, development costs, and research costs were calculated for the intervention period per primary care physician per 6 months. The mean costs of tests ordered per primary care physician per 6 months were assessed at baseline and follow-up. RESULTS: The new strategy was found to cost 702.00, while the feedback strategy cost 58.00. When including running costs only, the intervention was found to cost 554.70, compared with 17.10 per primary care physician per 6 months in the feedback arm. When excluding opportunity costs for the physicians' time spent, the intervention was found to cost 92.70 per physician per 6 months in the complete intervention arm. The mean costs reduction that physicians in that arm achieved by reducing unnecessary tests was 144 larger per physician per 6 months than the physicians in the feedback arm (P = 0.048). CONCLUSION: On the basis of our findings, including the expected non-monetary benefits, we recommend further long-term effect and cost-effect studies on the implementation of the quality strategy.     

Costs of occupational injuries and illnesses in California

OBJECTIVES: The purpose of this study was to estimate the annual incidence, the mortality, and the direct and indirect costs associated with occupational injuries and illnesses in California in 1992. To achieve this, we performed aggregation and analysis of national and California data sets collected by the U.S. Bureau of Labor Statistics, California Workers' Compensation Insurance Rating Bureau, California Division of Industrial Relations, the National Center for Health Statistics, and the U.S. Health Care Financing Administration. METHODS: To assess incidence of and mortality from occupational injuries and illnesses, we reviewed data from state and national surveys and applied an attributable risk proportion method. To assess costs, we used the cost-of-illness, human capital, method that decomposes costs into direct categories such as medical expenses and insurance administration expenses as well as indirect categories such as lost earnings, lost home production, and lost fringe benefits. Some cost estimates were drawn from California data, whereas others were drawn from a national study but were adjusted to reflect California's differences. Cost estimates for injuries were calculated by multiplying average costs by the number of injuries. For the majority of diseases, cost estimates relied on the attributable risk proportion method. RESULTS: Approximately 660 job-related deaths from injury, 1.645 million nonfatal injuries, 7,079 deaths from diseases, and 0.133 million illnesses are estimated to occur annually in the civilian California workforce. The direct ($7.04 billion, 34%) plus indirect ($13.62 billion, 66%) costs were estimated to be $20.7 billion. Injuries cost $17.8 billion (86%) and illnesses $2.9 billion (14%). These estimates are likely to be low because: (1) they ignore costs associated with pain and suffering, (2) they ignore home care provided by family members, and (3) the numbers of occupational injuries and illnesses are likely to be undercounted. CONCLUSION: Occupational injuries and illnesses are a major contributor to the total cost of health care and lost productivity in California. These costs are on a par with those of all cancers combined and only slightly less than the cost of heart disease and stroke in California. Workers' compensation covers less than one-half of the costs of occupational injury and illness.
