Abstract: Osteoporosis is a major health problem throughout the world. Despite the serious consequences of osteoporosis and fractures, many people with low bone mass and those with osteoporosis are unaware of it, and as a result are not taking preventive actions and are receiving no treatment. Nurses have a major role in prevention, assessment, and teaching related to osteoporosis. This review presents what is currently known about osteoporosis and identifies specific activities that fall within the scope of nursing practice. Evidence-based recommendations are presented and summarized.

Introduction

Osteoporosis, or porous bone, is the most common disease of bone and is characterized by low bone mass, deterioration of bone tissue, and compromised bone strength, leading to bone fragility and fractures.1,2 Osteoporosis may be due to too little bone formation or excessive bone loss.3,4 When bone loss is mild or moderate, it is referred to as osteopenia. More severe bone loss is referred to as osteoporosis, and osteoporosis in the presence of one or more fragility fractures is referred to as severe osteoporosis.5 Osteoporosis can be categorized as primary or secondary.69

The most common sites of fracture are the hip, spine, and wrist. Although osteoporosis and fracture are commonly thought of as limited to post-menopausal women, such fractures also occur at an earlier age in women and in men as well.1 Osteoporosis can occur at younger ages in individuals who did not achieve optimal bone mass during childhood and adolescence for a variety of causes, eg, poor nutrition, underlying disease, prolonged immobility, and extreme exercise leading to amenorrhea.3,9

Osteoporosis is a major public health issue because of the personal consequences of fracture and its resulting economic burden. Osteoporosis can be prevented, detected, and treated.1 Equally important, treatment can prevent subsequent fractures after a first osteoporosis-related fracture occurs.8 Many of the measures needed to prevent or minimize bone loss and fracture are within the scope of practice of nurses, nurse practitioners, and nurse midwives.

This article presents an overview of information needed by nurses to provide effective care for people at risk of osteoporosis and those receiving treatment for it. In addition to review of key publications from authoritative bodies concerned with osteoporosis and its treatment, such as the National Osteoporosis Foundation8 and World Health Organization (WHO),5 an extensive review of databases (ProQuest, PubMed, Cochrane Database) was conducted to identify articles related to osteoporosis and implications for nursing practice.

Epidemiology

The International Osteoporosis Foundation10 estimates that osteoporosis affects over 200 million people worldwide, although there is considerable variation in hip fracture risk and fractures across regions of the world. The National Osteoporosis Foundation8 estimates that more than 10 million Americans have osteoporosis and an additional 33.6 million have low bone density at the hip. It is predicted that by 2050, the worldwide incidence of hip fracture in women will increase by 240% and by 310% in men.11 The majority of fractures occur in individuals with low bone mass (osteopenia) rather than osteoporosis,8,12 suggesting the need to address bone loss and prevention of fractures early rather than late in life. Although bone loss and osteoporosis occur in all races and ethnic groups, some populations (eg, Asians and Caucasians) are at higher risk than others because of genetic differences, smaller body frames than other groups, and low consumption of calcium in Asians because of lactose intolerance.13

Reduction in estrogen production that occurs with natural or early menopause (younger than 45 years of age) is a major contributor to osteoporosis in women.14 Although approximately 30% of post-menopausal women have osteoporosis, it also occurs in older men, typically at around the age of 70 years,15,16 and the mortality rate in men is double that in women of similar age.10 It has been estimated that one in every two women and one in every five men are at risk for fractures related to osteoporosis during their lifetime.10,17 Because of the importance of osteoporosis as a factor that affects the quality of life of a large number of people, the US Surgeon General’s office issued its first report on bone health and osteoporosis in 2004.18

Pathophysiology

Osteoporosis is characterized by low bone mass or density and structural deterioration of bone tissue, leading to bone fragility and an increased risk of fractures of the hip, spine, wrist, and other bones.1,11 Bone density is determined by peak bone mass and the amount of bone loss. Peak bone mass refers to an individual’s maximum bone density and strength.1,19,20

Bone is comprised of collagen and calcium phosphate. Collagen provides a flexible framework and calcium phosphate strengthens and hardens the framework.1 Changes in bone occur throughout the life span. As older bone is removed through resorption by osteoclasts, new bone is formed and added to the skeleton by osteoblasts.21 Hormonal factors that regulate mineral metabolism and mechanical loading on bone (as in weight-bearing exercise) along with local damage stimulate the process of remodeling.18 During childhood and adolescence, bone is added more rapidly than old bone is removed. As a result, during childhood, adolescence, and young adulthood, bones become heavier, larger, and denser. Peak bone mass is typically reached before 30 years of age. At that time, bone formation slows and eventually is exceeded by removal, or resorption, of bone.1 Greater resorption of bone without formation of new bone results in low bone density and increased risk for fractures. Factors that affect bone remodeling include hormonal influences, stress to the skeleton through load-bearing physical activities, and weight-bearing exercise. In the absence of adequate amounts of mechanical loading and weight-bearing for sufficient periods, bone loss will occur. When the mechanical force produced by muscle is lost, as occurs in paralysis and immobilization, bone mass and strength are also rapidly lost.18

Although primary osteoporosis is common, secondary osteoporosis is also important. Secondary osteoporosis refers to osteoporosis that occurs as a result of other conditions or diseases or with the use of certain medications.6,7 It is characterized by bone loss greater than what would be expected for an unaffected individual of the same age, gender, and race.1,6,7 Causes include hypothyroidism, type 1 diabetes mellitus, malabsorption syndromes (eg, inflammatory bowel disease or following a gastric bypass), eating disorders (eg, anorexia nervosa), some genetic disorders (eg, cystic fibrosis), rheumatic and autoimmune disorders (eg, lupus, rheumatoid arthritis), and amenorrhea that occurs with extreme exercise. Other causes include high alcohol consumption, inadequate intake of calcium and vitamin D, lack of sun exposure, sedentary lifestyle, and lack of weight-bearing exercise. Medications that have been implicated in bone loss include corticosteroids, anticoagulants, proton pump inhibitors, diuretics, lithium, anticonvulsants, thyroxin, and chemotherapeutic agents.68,22,23

Consequences of osteoporosis

Fractures are the most significant consequence of low bone mass and osteoporosis.18 A fracture occurs when a force such as trauma is applied to osteoporotic bone. Fractures due to osteoporosis, which are commonly referred to as fragility fractures when they occur with falls from a standing position or occur spontaneously, are likely to affect mobility, quality of life, morbidity, and mortality. The most common fractures are those of the vertebrae (spine), proximal femur (hip), and distal forearm (wrist). Although hip fractures account for less than 20% of osteoporosis fractures,24 they are associated with serious disability and mortality; only one third of patients who experience hip fracture regain their prefracture level of function, one third require nursing home placement, and one fifth are likely to die within one year. Additionally, hip fractures are followed by a 2.5-fold increased risk of future fractures.8

Although the consequences of hip fracture are well known, less attention has been given to the effects of other types of osteoporotic fractures, including vertebral fractures, which often occur without an individual being aware of them. Such fractures can result in loss of height, kyphosis, and chronic back pain. Changes in posture associated with kyphosis may decrease an individual’s participation in everyday activities, such as bending and reaching, and in usual social activities.8 Restrictive lung disease can be a consequence of multiple vertebral fractures in the thoracic region, leading to increased risks associated with respiratory function. Constipation, abdominal pain and distention, reduced appetite, and early satiety may occur with vertebral fractures in the lumbar area because of alterations in abdominal anatomy.8

Although wrist fractures are generally less disabling than hip and vertebral fractures, they can nevertheless interfere with activities of daily living. Fractures of the pelvis and proximal humerus (shoulder) are also associated with increased morbidity and mortality.8 Wrist fracture and loss of height due to vertebral fractures strongly suggest low bone mass, and should prompt referral of the patient for evaluation for bone loss. Further, the occurrence of one fracture is highly predictive of subsequent fractures.25,26

In addition to the loss of mobility, function, and independence, other quality of life issues include isolation and decreased social interaction with others, depression, loss of self-esteem due to changes in lifestyle and appearance, anxiety, fear, and anger. Although outcomes such as depression are frequently reported in women with established osteoporosis, they may be overlooked by health care providers despite their significance in the lives of those who experience them.27

The financial consequences of osteoporosis and fractures are daunting. Direct financial expenditures for treatment of osteoporotic fracture are estimated at $10–$15 USD billion annually.2830 A majority of these costs are related to inpatient hospital care and do not include the costs of treatment for individuals without fractures, or the indirect costs of lost wages or productivity of either individuals with osteoporosis or their caregivers. Osteoporosis-related fractures create a heavy economic burden, causing more than 432,000 hospital admissions, almost 2.5 million medical office visits, and about 180,000 nursing home admissions annually in the USA. Although hip fractures account for 14% of osteoporotic fractures, they account for 72% of fracture costs.8

Osteoporosis is often ignored by health care providers, even when the individual has experienced a hip or other fracture with a high probability of it being due to bone loss and osteoporosis.12,31,32 Fewer than 20% of women with fractures likely due to low bone density are subsequently assessed for and treated for osteoporosis in the US and other countries.3133 Equally important is that among patients who experience hip fracture, almost half have a history of previous bone fracture without subsequent follow-up or treatment.33 Lack of health care providers’ attention to these issues strongly suggests the need to identify patients at increased risk for or with osteoporosis so that follow-up testing and treatment can be initiated. Assessment of risk factors is key to early detection and treatment.

Risk factors for osteoporosis

Many factors associated with osteoporosis cannot be modified, ie, gender, age, low body mass index, ethnicity, family history of osteoporosis and fractures, presence of some health conditions, and some medications essential for an individual’s health and well-being. Other risk factors, however, can be identified and modified.22 These are summarized in Table 1, along with actions that can be recommended by nurses to patients. If medications that increase the risk of bone loss cannot be modified, other strategies (eg, calcium and vitamin D supplementation, weight bearing exercise, balance exercises) should be initiated to reduce the risk of osteoporosis, falls, and fractures.22,27

Table 1 Modifiable osteoporosis risk factors and recommended

Because of the serious consequences of fracture due to low bone mass or osteoporosis described above, several assessment tools have been developed to assess the individual’s risk for osteoporosis and fracture. It is recommended that patients be assessed using one of these assessment tools yearly.5,14 The Fracture Risk Assessment Tool (FRAX), developed by the WHO5 in 2008 (Geneva, Switzerland), is a computer-generated algorithm that provides an estimate of the risk for fracture in order to guide treatment decisions. An individual between 40 and 90 years of age is assessed for risk of major osteoporotic fracture in the next 10 years based on validated clinical risk factors and bone mineral density (BMD) test results if available.3437 The clinical risk factors include age, body mass index, history of fracture, high alcohol intake, smoking, and presence of rheumatoid arthritis or any other secondary causes of osteoporosis. QFracture® (ClinRisk Ltd., Leeds, UK) and FORE 10-Year Fracture Risk Calculator (Foundation for Osteoporosis Research and Education, Oakland, CA, USA) are other algorithms developed to predict the risk of osteoporotic fracture.38,39 The Male Osteoporosis Risk Estimation Score (MORES)40 is used to identify men 60 years and older who are at risk for osteoporosis and who should be referred for confirmatory diagnostic dual-energy X-ray absorptiometry. MORES includes three variables, ie, age, weight, and history of chronic obstructive pulmonary disease. A MORES score of 6 or greater has been shown to have an overall sensitivity of 93%,16,41 indicating that it predicts osteoporosis in men correctly 93% of the time. These fracture risk assessment tools are used to assess risk rather than to monitor treatment. Assessment of frailty in elderly patients with the Study of Osteoporosis index, which is based on weight loss, the subject’s inability to rise from a chair five times without using the arms, and a reduced energy level, has been found to be useful in assessing risk for falls due to frailty.42

The Surgeon General’s report18 on bone health identifies nurses as being in an ideal position to administer an osteoporosis risk factor assessment and to use the results to identify at-risk individuals. An important nursing role is the identification of those factors that increase a patient’s risk for osteoporosis and for falls and discussion of strategies to address modifiable risk factors with the patient. Further, if a patient is identified as at increased risk for bone loss and osteoporosis based on assessment of risk factors, nurses are in a position to refer the patient to the primary care provider for appropriate follow-up testing and treatment. Diagnostic testing and treatments are discussed later in this paper.

Diagnosis of osteoporosis

Many people are unaware that they have low bone mass or osteoporosis until their first fragility (low-impact) fracture occurs. Measurement of BMD by dual-energy X-ray absorptiometry scan is used as a proxy for bone strength; BMD accounts for approximately 70% of bone strength.43 BMD test results reflect comparison of an individual’s bone density with the ideal or peak bone density of a healthy 30-year-old adult. BMD is reported as a T-score, which reflects the standard deviation from the norm of a healthy young adult. Thus, T-scores of +1 to −1 are interpreted as normal bone density. Scores between −1 and −2.5 indicate low bone mass or osteopenia. Osteoporosis is defined by the WHO as T-scores of −2.5 and below.25 T-scores lower than −2.5 with one or more osteoporotic fractures are indicative of severe osteoporosis.5 T-scores and their interpretation are summarized in Table 2. Z-scores are also reported and reflect comparison of a patient’s BMD with an age-matched and gender-matched sample. Because low BMD is common in older adults, the Z-score can be misleading and is less valuable than the T-score.44

Although BMD scores are used widely, controversy exists about the BMD T-score of −2.5 or below as a criterion for osteoporosis and as a threshold for treatment. Further, it is not known if this is an appropriate diagnostic criterion for men, children, and across ethnic groups. The WHO25 emphasizes the need to consider other factors in addition to T-scores when determining need for treatment of low bone density. It is important to note that research has demonstrated that BMD test results obtained one year before a fracture occurred were not diagnostic of osteoporosis in a cohort of 149,524 white post-menopausal women aged 50–104 years recruited from primary care practices in the USA. In fact, only 18% of women who experienced fractures of the wrist or forearm, hip, rib, or spine met the threshold of −2.5 for treatment.12 Thus, the results of BMD testing need to be interpreted with caution.

The recommendations for testing for low bone density and osteoporosis have changed over time and differ slightly between organizations making recommendations.8,14,17 The National Osteoporosis Foundation8 recommends BMD testing for all women 65 years of age and older and post-menopausal women under 65 years of age, based on their risk factor profile as well as all men 70 years of age and older and men aged between 50 and 69 years of age who are at risk for osteoporosis. An expert panel convened by the National Institutes of Health2 in 2000 recommended BMD testing for people taking corticosteroids for 2 or more months and those at high risk for osteoporosis fractures. BMD should be tested no more frequently than every 2 years.41

Although the majority of cases of osteoporosis are considered primary and related to decreased estrogen production in women with menopause and aging in both men and women, testing for causes of secondary osteoporosis may be indicated because the treatment of secondary osteoporosis differs from that of primary osteoporosis, and usually involves treatment of the causes of secondary osteoporosis. Laboratory tests that may be used for initial evaluation of a patient for osteoporosis and for diagnosis of secondary osteoporosis are identified in Table 3.

Treatment of low bone mass/osteoporosis

Treatment of patients with low bone mass or osteoporosis includes both pharmacologic and nonpharmacologic approaches. Both approaches have implications for nurses, including ensuring that patients are knowledgeable about the medications that are prescribed and their correct administration to ensure that they are as effective as possible, as well as instructing them about the nonpharmacologic management of low bone mass or osteoporosis. Nonpharmacologic intervention includes modification of general lifestyle factors, such as a healthy diet containing calcium and vitamin D, participation in weight-bearing exercise and exercises that enhance strength and balance, and avoidance of smoking and high alcohol consumption (see Table 4).

Nurses’ role in osteoporosis

Patients with osteoporosis or low bone mass are generally treated, if they are diagnosed and treated at all, in outpatient settings. However, because of the high prevalence of osteoporosis, many hospitalized patients are likely to have low bone mass or osteoporosis but are often unaware of it and are often untreated. Several studies have demonstrated that more than 80% of older patients with new fractures, including hip fracture, do not receive treatment for osteoporosis despite the strong likelihood that the fractures are due to low bone mass, the wide availability of effective medications, and the likelihood of future fractures in both men and women.3133 A recent study revealed that 64.3% of 65,344 women aged 55 years and older from a US managed care population received no pharmacologic treatment within one year after receiving a diagnosis of osteoporosis.31 Research has also shown that long-term care residents, most of whom are at high risk for osteoporosis and falls, do not receive the recommended assessments of risk factors or BMD. As a result, undertreatment and lack of treatment are common.45 Inadequate attention to detection and treatment of osteoporosis presents an opportunity for hospital-based nurses and those in long-term care facilities to address the issue.

In an effort to address the gap in management of osteoporosis in high-risk hospitalized patients, bone health teams, also referred to as fracture follow-up teams or fracture liaison services, consisting of members of a variety of health care professionals, are being implemented to raise awareness among health care providers about osteoporosis, ensure that patients are assessed for risk of low bone density and risk of fracture, and provide preventive and therapeutic management of osteoporosis.4649 Again, nurses are key to the success of these interdisciplinary efforts. They are positioned to take the lead in addressing this issue by assessing bone health and osteoporosis risk factors in all age groups and in all settings in which they interact with patients.

The role of nurses in caring for patients with osteoporosis or at risk for osteoporosis, regardless of setting, includes enhancing patients’ knowledge about osteoporosis and promoting behavior change. Specific nursing actions include: providing patient education across the lifespan about bone health and prevention of osteoporosis and fractures, including discussing strategies to ensure bone health in adolescents as well as young adults and older patients;14 assessing patients’ risk for low bone density or osteoporosis; providing education to patients with or at risk of osteoporosis and their families about pharmacologic and nonpharmacologic treatment strategies; educating patients and their family caregivers about the risk for falling and strategies to prevent falls at home; assessing the risk factors for falls and implementing strategies during a patient’s hospitalization to decrease the risk of falls and fracture in those with or at risk for osteoporosis; providing nursing care for patients at risk for complications of osteoporosis; and promoting adherence to medication and lifestyle changes.

Enhancing patients’ knowledge

Many interventional studies have shown that enhanced knowledge encourages patients to seek additional information about osteoporosis and leads to lifestyle changes.5053 Studies conducted in the USA and other countries have shown a low level of knowledge about osteoporosis among general groups of women and men and those at increased risk for osteoporosis because of age, having first-degree relatives with osteoporosis or fracture, having a disability, or receiving chemotherapeutic agents or other medications that negatively affect bone density or other risk factors.5462 Research has shown that although participants may have good knowledge of what osteoporosis is, they generally have a low level of understanding of the role of medication in reducing fracture risk, various concerns about the side effects of medication, poor understanding of the causes of osteoporosis, and uncertainty about how it can be controlled.63

Demographic and social factors have been linked to a low level of knowledge about osteoporosis. Studies have found that being male, having English as a second language, and not exercising are associated with a lower level of knowledge.51 Prior studies have also shown that those who are unemployed or have a lower income are at greater risk for osteoporosis and low-impact fractures.64,65 These findings may reflect a lack of opportunity to participate in behaviors known to affect bone health. Although men have a high mortality rate after sustaining a low-impact fracture,66 most osteoporosis educational efforts up to this point target women and are delivered in English. The findings of these studies suggest the need to target educational interventions to men, those with low income, those who are unemployed, and groups in which English is not the primary language to reduce the risk of future fractures in these high-risk groups.67 Studies are needed to evaluate the effectiveness of such interventions in these populations.

Some osteoporosis education materials have been translated literally to reach those who do not speak English or those for whom English is a second language. However, there may be issues with cultural translation that limit the understanding and applicability of the information provided for these populations.67 Therefore, nurses need to tailor their educational interventions to the culture, language, and needs of specific ethnic groups.

In providing information about osteoporosis to patients, including explanations of what osteoporosis is, its consequences, and the factors that increase its likelihood and the risk for falls, nurses need to have an adequate breadth and depth of knowledge about osteoporosis and its treatment. Research, however, has demonstrated inadequate knowledge about osteoporosis among nursing students in the final year of their nursing education and prior to their clinical internship.68,69 In order to provide accurate information about medications prescribed to treat osteoporosis, nurses must also be knowledgeable about the correct method of administration. Although bisphosphonates have been shown to be effective in increasing BMD and reducing the risk for fractures, these medications are effective only when administered correctly. A recent study70 demonstrated that in a sample of nurses and patient support workers from long-term care facilities, only 52% of the nurses and 8.7% of the patient support workers responsible for administration of medications administered bisphosphonates correctly (ie, gave the medication before meals, with water, separated from all other medications, with the patient in an upright position for at least 30 minutes).

Strengthening patients’ health beliefs and promoting behavior change

Studies have shown that appropriate pharmaceutical care improved osteoporosis-related knowledge, quality of life, and satisfaction in post-menopausal osteoporotic women.70 Pharmaceutical care includes a medication review, education on osteoporosis, risk factors, lifestyle modifications, goals of therapy, side effects, and the importance of medication adherence.70 Despite the efficacy of treatments in reducing fracture risk, poor adherence among patients is a problem in osteoporosis.71 Factors that influence health behaviors related to osteoporosis include lack of knowledge related to osteoporosis, lack of belief in the benefits associated with prevention, lack of motivation to overcome barriers to osteoporosis prevention, lack of social support, inadequate access to care and behavior change opportunities, and language barriers. The majority of the successful interventions involved more than one type of intervention (eg, education combined with self-management) and use of strategies for engaging patients to influence their health beliefs and attitudes about osteoporosis and recommended medications.72,73 Many studies have demonstrated that health beliefs or self-efficacy play an important role in adoption and maintenance of healthy behaviors for osteoporosis prevention and treatment adherence.51,74,75

Studies have shown that both self-efficacy and outcome expectations play an important role in exercise, dietary behaviors, and medication adherence in adults.50,51,7678 Nurses can apply these intervention strategies in practice to promote behavior changes.58,7981 Nurses can be part of the efforts to prevent second fractures in patients who have experienced a first fracture.4649

Research51,58,62,8287 has demonstrated that well planned and executed theory-based educational interventions can be effective in increasing consumption of foods rich in calcium and vitamin D or use of supplements, increasing participation in exercise, increasing BMD testing, and modifying other lifestyle behaviors that increase the risk for bone loss. However, few patients receive adequate education unless they are participants in research studies. Information developed for the public and guidelines for assessing and treating patients with osteoporosis are available from many agencies and organizations, such as the National Institutes of Health and the National Osteoporosis Foundation,1–3,8 and can be used effectively to introduce the topic to patients and to follow up accordingly.

Another major challenge is that many patients with osteoporosis take their prescription medications incorrectly, infrequently or not at all, delay obtaining their medications, or take them in the wrong dosage or at the wrong time.88 Poor compliance with osteoporosis treatment and resistance to use of osteoporosis medications significantly lower treatment-related outcomes, including slowed bone loss in elderly patients, and result in large groups of patients being untreated. As a result, the public health objective to reduce fractures is not met. The role of nurses in improving adherence and persistence includes understanding the factors that affect nonadherence, monitoring the effects and side effects of medication, and identifying patients who are at high risk of poor adherence over time.36,71,88 Studies are needed to identify strategies for improving adherence with medication regimens, recommending BMD testing, and improving lifestyle behaviors over time.

Research has shown that although patient education is necessary to effect behavior change, it is not sufficient.89 If patients undergo BMD testing and have the results explained to them, they are more likely to take measures to reduce their risks, such as increasing their intake of calcium and vitamin D, than patients who do not undergo BMD testing.90 Thus, encouraging patients to undergo BMD testing and interpreting their BMD scores to them may increase the likelihood that they will follow the treatment plan and comply with recommendations for medications and lifestyle changes.

In addition to educating patients about osteoporosis and risk factors for bone loss, nurses also need to focus on prevention of falls in those at risk. Several specific approaches have demonstrated benefits, including muscle strengthening and balance retraining, professional home hazard assessment and modification, vision check, and medication review. Nurses need to take responsibility for monitoring patients’ arrays of medications to identify those that affect bone health or increase the risk of falls. Nurses then need to bring these medications to the attention of the patient’s primary care provider to determine if all are needed or others with less potential to cause bone loss can be substituted, along with the need for supplemental calcium and vitamin D if warranted. Table 5 identifies specific strategies designed to reduce the risk for falls.

Table 5 Falls prevention

Conclusion

The number of people with low bone mass or osteoporosis around the world is high and increasing rapidly with the aging of the population. Many people are unaware that they are at risk for developing osteoporosis or already have it. Prevention of bone loss and falls is a major goal that if implemented will prevent fractures, decrease morbidity related to fractures, improve quality of life, and reduce mortality. Nurses who are knowledgeable about osteoporosis and its prevention are in a key position to make a significant difference to the quality of life of people who might otherwise experience life-threatening fractures, disability, and premature death. As stated earlier, many measures needed to prevent or minimize bone loss are within the scope of nursing. All patients deserve to learn about the often preventable risks of osteoporosis so that they can live their lives with the quality of life they desire.
