ARE TRAUMATOLOGISTS TREATING OSTEOPOROSIS TO PREVENT NEW FRACTURES IN BRAZIL?

OS TRAUMATOLOGISTAS TRATAM OSTEOPOROSE, PARA PREVENIR UMA NOVA FRATURA, NO BRASIL?

ABSTRACT

Objectives:

To determine the proportion of traumatologists who investigate osteoporosis in elderly patients with fractures and recommend secondary prevention of osteoporotic fractures.

Methods:

We distributed questionnaires to 244 physicians attending the 2015 Brazilian Congress of Orthopedic Trauma. We determined the respondents’ profiles and assessed how they investigated and treated osteoporosis in elderly patients with fractures.

Results:

Overall, 32% of the respondents reported that their knowledge level regarding osteoporosis ranged from 0-5 (out of 0-10). In total, 42% of the participants reported that they usually requested DXA for elderly patients with fractures and less than 30% reported prescribing supplemental calcium and/or vitamin D. We considered physicians conducting a complete treatment for the patient as those who in addition to requesting DXA prescribed supplemental calcium, vitamin D, and specific medications for their elderly patients, and recommended non-pharmacological measures. Only 0.8% of the participants fulfilled all these criteria. In addition, 47% of the traumatologists reported that they did not treat osteoporosis directly but instead, referred osteoporotic patients to a qualified physician.

Conclusion:

Less than 50% of the surveyed traumatologists investigated and performed secondary prevention against osteoporotic fractures after treating an elderly patient with a fracture. Level of evidence III, Economic and Decision Analyses - Developing an Economic or Decisions Model.

RESUMO

Objetivo:

Avaliar a proporção de traumatologistas que investigam a osteoporose nos pacientes idosos com fraturas e recomendam a prevenção secundária das fraturas osteoporóticas.

Métodos:

Distribuímos questionários para 244 médicos participantes do Congresso Brasileiro de Traumatología Ortopédica em 2015. Determinamos o perfil dos mesmos e avaliamos como os entrevistados investigam e tratam a osteoporose nos pacientes idosos com fraturas.

Resultados:

Entre os entrevistados, 32% relataram que seu nível de conhecimento sobre osteoporose seria algo entre 0 e 5 (de 0 a 10). No total, 42% dos participantes relataram que frequentemente solicitam DXA para pacientes idosos com fraturas, mas menos de 30% relataram prescrever suplementação com cálcio e/ou vitamina D. Consideramos como prescritores do tratamento completo para o paciente aqueles médicos que, além de solicitar DXA, prescrevem suplementação de cálcio, vitamina D e medicamentos específicos para seus pacientes idosos, além de recomendar medidas não farmacológicas. Apenas 0,8% dos participantes preencheram todos esses critérios. Além disso, 47% dos traumatologistas relataram que não tratam a osteoporose, mas encaminham seus pacientes com osteoporose para um médico que o faz.

Conclusão:

Menos de 50% dos traumatologistas pesquisados investigam e realizam prevenção secundária contra fraturas osteoporóticas após tratamento de paciente idoso com fratura. Nível de evidência III, Análises econômicas e de decisão - Desenvolvimento de modelo econômico ou de decisão.

INTRODUCTION

Osteoporosis is characterized by decreased bone mineral density and disruption of the bone microarchitecture leading to increased bone fragility.¹ It is defined by the World Health Organization as a bone mineral density T-score below −2.5 standard deviations determined by dual-energy x-ray absorptiometry (DXA).² According to current estimates, osteopenia and osteoporosis affect millions of individuals worldwide.^2–5 Osteoporosis, which often affects elderly patients, may be a silent disease until complicated by a fracture, which may occur with minimal trauma or even in its absence. Fractures of the vertebra, proximal femur, and distal radius are considered sentinel events.⁵ Up to 50% of women and 20% of men older than 50 years are estimated to have an osteoporotic fracture throughout life.³

In this context, it is important to consider the costs associated with hospital admissions, outpatient care, and medical procedures to treat these fractures, which are potentially preventable in a large proportion of patients.^5–8

We must understand the importance of properly treating osteoporosis to prevent serious complications such as new fractures and secondary deformities, chronic pain, and loss of independence. These measures may also reduce mortality in the elderly population. Still, we observe that the diagnosis and treatment of this disease are flawed in many countries worldwide.^1,4,9

The aim of this study was to assess the percentage of orthopedic traumatologists in Brazil who investigate and treat osteoporosis with the objective of preventing new fractures in elderly patients.

MATERIALS AND METHODS

We invited participants of the 21^st Brazilian Congress of Orthopedic Trauma (Congresso Brasileiro de Trauma Ortopédico, CBTO), held in May 2015 in Belém (Pará, Brazil), to fill out an anonymous questionnaire. The questionnaire consisted of multiple-choice questions and was answered by 244 physicians, of whom 184 were orthopedic traumatologists and 60 were residents in orthopedics and traumatology. The data obtained were analyzed and correlated using the programs Excel 2011 and EpiInfo, version 3.5.2.

The research project of this study was approved by the Ethics Committee in Research (CAAE 39276614.5.0000.5479). The physicians who filled out the questionnaires signed a Free and Informed Consent Form. We determined the profile of the participating physicians by including two questions in the survey: (1) For how long (in years) have you been practicing orthopedics? and (2) In which region of Brazil do you practice? The answers to these questions were compared with deidentified data from the Brazilian Society of Orthopedic Trauma (Sociedade Brasileira de Trauma Ortopédico, SBTO) in order to evaluate how the participants would compare with the actual profile of the overall sample of orthopedic traumatologists in Brazil.

We assessed the degree of knowledge of the participants regarding osteoporosis, and whether they investigate and treat the disease, and if they do so, how they conduct the investigation and treatment. We also questioned the degree of knowledge that the surveyed traumatologists consider to have regarding the disease, and how much they wish they knew about it. In order to assess the knowledge about the disease, we asked the participants to select among six options the correct T-score cutoff value that establishes the diagnosis of osteoporosis, as defined by the World Health Organization.² To evaluate if the participants performed any investigation or treated osteoporosis, we asked them if after diagnosing and treating a fracture in an elderly patient, whether they request any additional tests to identify or confirm the occurrence of osteoporosis. We also asked if they recommend non-pharmacological measures and prescribe supplemental calcium, vitamin D, or any specific medication (antiresorptive agents or bone forming agents) to at least 50% of their patients.

For the purpose of this research, we considered as managing osteoporosis adequately those physicians who:

• Requested DXA to investigate or confirm a diagnosis of osteoporosis;

• Answered the correct T-score value that establishes the diagnosis of osteoporosis (-2.5 standard deviations);

• Prescribed supplemental calcium and vitamin D to at least 50% of their elderly patients diagnosed with a fracture;

• Prescribed any medication specifically to treat osteoporosis to at least 50% of their elderly patients diagnosed with the disease;

• Recommended some type of non-pharmacological treatment/prevention (such as fall prevention, smoking cessation, decrease in alcohol consumption, or regular physical activity);

• Referred the patient to a specialist qualified to treat osteoporosis (for those participants who did not treat osteoporosis).

RESULTS

Table 1 shows the distribution of the participants according to the region in Brazil where they practice orthopedics. Excluding the residents who answered the questionnaire, 40% of the participants reported to have been practicing orthopedics for less than 10 years, whereas the remaining 60% reported more than 10 years of practice. Data obtained from the SBTO showed that 27% of the members of the society had concluded training less than 10 years before the data were collected, whereas 73% had done so more than 10 years before.

• Total n - Total number of participants; % - Percentage; ER n - All participants, excluding residents. SBTO - Percentage of members of the Brazilian Society of Orthopedic Trauma (Sociedade Brasileira de Trauma Ortopédico) distributed by geographical region of practice.

When questioned about their degree of knowledge about osteoporosis on a scale between 0 (zero) and 10 (ten), 32% of the participants responded knowing between 0-5, and 68% reported knowing between 6-10. A total of 97.5% of those who reported knowing between 0-5 answered that they would like their degree of knowledge about osteoporosis to increase to 6-10.

When we asked if the physicians would be interested in participating in a workshop/seminar if promoted by the SBTO, Brazilian Society of Orthopedics and Traumatology (Sociedade Brasileira de Ortopedia e Traumatología, SBOT), or some other medical society or recognized educational institution, 91% responded that they would. When we assessed the degree of knowledge of the participants about osteoporosis, 76.5% of the residents and 66% of the traumatologists answered the correct T-score cutoff value. A total of 42% of the participants responded that they request DXA to investigate or diagnose osteoporosis in an elderly patient with a fracture, but when we analyzed only the responses given by residents, the corresponding rate was much lower (16%). Among the physicians who reported requesting DXA, 35% answered incorrectly the T-score cutoff value that determines the diagnosis of osteoporosis.

When we excluded the responses by residents, we found that 18% of the respondents prescribe vitamin D, 24% prescribe calcium, and 27% prescribe antiresorptive/bone forming agents during follow-up of elderly patients diagnosed with a fracture. Among medical residents, the corresponding percentages are 3.4% for supplemental calcium and vitamin D and 1.6% for specific medications. The corresponding values are 3.4% for supplemental calcium and vitamin D, and 1.6% for specific medications.

As for non-pharmacological treatment, 41% of the participants reported as offering this recommendation, with similar rates between traumatologists and residents (45.7% and 38.9% respectively).

Overall, 47% (n=103 out of 244) of the respondents reported requesting DXA, of whom 65% (n=67 out of 103) knew the correct T-score value. A total of 34 respondents (52% of 67 or 14% of 244) also prescribe supplemental calcium and vitamin D, and nine of these (26% of 34 or 3.6% of 244) prescribe a medication specifically to treat osteoporosis. Only two respondents (22% of 9 or 0.8% of 244) reported that they conduct a complete treatment in which they request and interpret the tests, prescribe supplemental calcium, vitamin D and appropriate medications, and recommend non-pharmacological treatment (Figure 1).

Figure 1
Percentages of physicians who conduct a complete treatment of osteoporosis. Among all participants, the percentages of those who request DXA (DXA), also knows the correct T-score cutoff value (DXA + T-score), also prescribes supplemental calcium and vitamin D (DXA + T-score + Ca + Vit D), also prescribes specific medications (DXA + T-score + Ca + Vit D + Sp Med [antiresorptive or bone forming agents]), and also recommends non-pharmacological measures to their patients (DXA + T-score + Ca + Vit D + Sp Med + Recomm).

Overall, 47% of the traumatologists and 43% of the residents reported not treating osteoporosis but instead, referring their patients to a medical professional who is qualified to do so.

DISCUSSION

When we compared the profile of the participants, we observed that they share similar characteristics with members of the SBTO in terms of the region of the country where they practice. The values remained within 95% confidence intervals for the Midwest, Southeast, and Northeast regions, but were above the interval for the Northern region and below it for the Southern region. This may be explained by the fact that the meeting was located in the Northern region of Brazil (Belém, PA) and also by the continental dimensions of our country. Still, the similarities between the groups confirm that our cohort was representative of the overall members of SBTO.

There was a greater participation of physicians who had finished training less than 10 years before the survey when compared with data provided by SBTO. In our understanding, this is due to the fact that individuals who have been practicing for less time tend to participate more frequently in workshops and meetings, seeking to improve knowledge to make up for a shorter experience, and possibly a greater academic commitment, availability, and disposition to participate in the study and fill out the questionnaire. Regarding secondary prevention, traumatologists in practice for more than 10 years have a greater commitment to research, knowledge, and treatment of osteoporosis, and are more prone to recommend secondary prevention, whereas those with a shorter practice experience refer their patients to specialized care (Figure 2).

Figure 2
Distribution of follow-up scenarios according to the duration of orthopedics practice. The bars show the percentages of participants who reported requesting DXA (DXA), knowing the correct T-score to establish a diagnosis of osteoporosis (T-score); recommending supplemental calcium and vitamin D (Ca + Vit D), prescribing specific medications for osteoporosis (Spec Med), recommending non-pharmacological measures (Recomm), and referring the patient when not performing treatment (Referr).

The large difference observed between the numerical values obtained with the questions “How much do you think you know?” (average = 6) and “How much would you like to know?” (average = 9.3) suggests that the participants are interested in osteoporosis and are willing to learn about it, a fact that was confirmed when 90% answered that they would have an interest in participating in a workshop/meeting organized on this subject by a recognized medical society or institution.

When we assessed specifically the participants’ technical knowledge about osteoporosis treatment, most traumatologists and residents knew the correct T-score value; however, less than half of them reported requesting additional tests to investigate the diagnosis or support the treatment, with only 16% of the residents having reported doing so. This finding is concerning because it demonstrates an inconsistency in the process of specialized medical training that needs to be corrected. The National Osteoporosis Foundation and the World Health Organization recommend that all adults older than 50 years who are diagnosed with a fracture should be investigated with DXA.^2,10

The treatment of osteoporosis involves both pharmacological and non-pharmacological measures. Medical entities such as the Brazilian Society of Endocrinology and Metabolism (Sociedade Brasileira de Endocrinología e Metabologia) and the World Health Organization have demonstrated that the amount of calcium and vitamin D consumed by the population usually falls short of the actual requirement, and their supplementation is often necessary.^2,5,11,12 Regarding specific medications to treat osteoporosis, such as antiresorptive and bone forming agents, several studies and systematic reviews have demonstrated their efficacy in secondary prevention.^13–16

We considered as appropriately recommending secondary prevention those traumatologists who reported that they investigated the occurrence of osteoporosis, knew the definition of the disease according to current and established criteria, prescribed pharmacological treatment and supplementation, and recommended non-pharmacological measures.¹⁷ Only 0.8% of the traumatologists and none of the residents fulfilled all these criteria.

We also considered as appropriately managing the patients those surgeons who after treating an osteoporotic fracture, referred the patient to a specialist qualified to treat the osteoporosis. Less than half of the traumatologists (47%) and residents (43%) reported doing that. This fact is concerning, considering that many fractures could be avoided if the underlying disease were treated correctly.^5,7,13,18,19 Although this is a global problem, it has some particularities in Brazil, as reflected by a study among physicians members of the Brazilian Society of Internal Medicine (Sociedade Brasileira de Clínica Médica) that has shown that only 35% of the general practitioners believe that osteoporosis treatment is effective.²⁰

CONCLUSION

Our results show that less than half of the traumatologists in Brazil diagnose and recommend secondary prevention for osteoporotic fractures, only 0.8% of them treat these patients correctly, and 47% refer the patients to specialized care.
