In reply: How to prevent glucocorticoid-induced osteoporosis
In Reply: I thank Drs. Bachmeyer and Gauthier for their kind comments. My review was limited to therapies currently available by prescription in the United States; therefore, strontium ranelate was not included. I agree with their comment that prospective studies are required to consider strontium ranelate as an effective therapy for glucocortocoid-induced osteoporosis.

Electronic medical records
To the Editor: Like Dr. Hanlon (Cleve Clin J Med 2010; 77:408–411), I too am alarmed by the inability of electronic medical records to incorporate whole language. Physicians can make treatment errors when they fail to include contextual factors in their diagnosis and treatment plans. The social and circumstantial complexities of a patient’s life cannot be parsed by computer systems that can only “search” bullet points. The current template-driven systems were originally designed for billing and now are touted for “quality measurements.” They could tell us whether a patient’s hemoglobin A1c was at goal, or if she was “noncompliant” and hadn’t filled a prescription; they could not tell us that a psychologically abusive husband would not allow her to purchase her diabetes medications (this actually happened to one of my patients). I would argue that addressing the abuse is more important to her health. Yet we are all being pushed, like teachers teaching to a standardized test, to hit certain “benchmarks,” in order to be called “quality” physicians.
Since it is unlikely that the tide will turn back to a written record, physicians should be demanding rapid deployment of computer systems, now in development, that can analyze whole language and find information in context. This technology is out there and needs aggressive support.
Texting contractions, Twitter, and the rest are chipping away at the concept of narrative. Our patients’ lives are worthy of a narrative, not the bullet points and cut-and-paste we are forcing their lives and health into.

Kidney stones
To the Editor: Thanks for the excellent review articles on nephrolithiasis in your October 2009 issue.1,2
Dr. Hall1 cites studies in which patients given the alpha blocker tamsulosin (Flomax) or the calcium channel blocker nifedipine (Procardia) had improved rates of kidney stone passage compared with placebo. As a primary care physician, I am often confronted with the challenge of managing a patient who is waiting for a kidney stone to pass while taking tamsulosin. Is Dr. Hall aware of any clinical studies, or at least theoretical reasons, which would support adding nifedipine in such cases?
Secondly, Dr. Hall cites studies that demonstrated that a higher intake of dietary calcium is actually associated with fewer calcium stone events in both men and women. An unanswered question is whether patients taking calcium supplements for osteoporosis or osteopenia can safely continue to do so after a calcium stone event, or indeed, whether calcium supplementation might actually be helpful in preventing a recurrent calcum stone.
If there is an absence of randomized studies to answer these questions, Dr. Hall’s recommendations based on his expert experience would be most welcome.

In reply: Kidney stones
In Reply: I thank Dr. Keller for his kind letter.
With respect to expulsive therapy, Dellabella et al1 randomly assigned 210 patients to receive nifedipine, tamsulosin, or phloroglucinol. All the patients also received a corticosteroid. The most effective therapy was tamsulosin, though this was not a placebo-controlled study. In a separate study, Borghi et al2 compared methylprednisolone plus nifedipine and methylprednisolone plus placebo. The nifedipine-methylpednisolone combination seemed to result in more prompt stone passage.
With respect to calcium supplements in calcium kidney stone disease, Curhan et al3 prospectively examined stone risk associated with dietary calcium as well as calcium supplements. This seemed to show that with calcium supplements there was no increased risk, and there may have even been some benefit. In another study by Borghi et al,4 normal dietary calcium intake was shown to be associated with lower stone risk than a low calcium intake. Further, the study by Curhan et al3 seemed to indicate the same.

Fragility fractures in chronic kidney disease: A clarification of views
To the Editor: I was pleased to see my article on fragility fractures in patients with chronic kidney disease (CKD) in the Cleveland Clinic Journal of Medicine1 and your preamble Letter from the Editor.2
However, Dr. Coco’s accompanying editorial3 misquoted a particular point I cautiously and consistently make—not only in the CCJM article, but in other invited papers on the topic of fractures in CKD. I specifically state that bisphosphonates should only be considered in stage 4–5 CKD in fracturing patients, not just those with “low bone mineral density,” who have clear-cut osteoporosis by exclusion of other causes of fractures in this population. Hence, Dr. Coco’s statement that “… the author advocates the use of bisphosphonate therapy in patients with chronic kidney disease who have low bone mineral density” is inaccurate.
If one carefully reads the last four paragraphs of my paper on page 721, one will see that I emphasize this caution repeatedly and even specifically state: “Treating only on the basis of low bone mineral density and other risk factors seems to be associated with greater risk than benefit.”
Thank you for your consideration.

In reply: Fragility fractures in chronic kidney disease: A clarification of views
In Reply: Bone disease in the patient with chronic kidney disease (CKD), especially in the presence of a fracture, is indeed a vexing problem. Clinically, it is very difficult to differentiate between low bone turnover—not uncommon in patients with CKD—and patients who have osteoporosis. Clinically, these patients present similarly: both can have abnormal bone density measurements (usually low bone mineral density with T scores less than −2.5 standard deviation), and both can have fractures. But both should not be treated the same without further evidence.
In Dr. Miller’s article, bisphosphonate and other therapies are named as possible treatments for “osteoporosis” in patients with CKD stages 1 through 3. “Treatment decisions are more difficult … in stage 4 and especially stage 5 chronic kidney disease with fragility fractures…."
Dr. Miller indeed states that “patients without fractures with stage 5 … should not be given bisphosphonates …” He also states, “Treating only on the basis of low bone mineral density … seems to be associated with greater risk than benefit.” In Dr. Miller’s opinion, the latter group of patients may be treated with a bisphosphonate if there has been a fracture. However, many of these patients may have fractured because of low turnover bone disease; unfortunately, they cannot have “clear-cut osteoporosis by exclusions of other causes.” Bisphosphonate therapy may further suppress bone activity (if there is any activity left) and may predispose to extraosseous and cardiovascular calcifications and further non-bone pathology.
Dr. Miller does caution regarding unknown risks in these patients with advanced kidney disease.
Treating metabolic bone disease is certainly not straightforward, especially when present in the fracturing renal patient. We need more evidence before making treatment paradigms.

Letter to the Editor
Prado et al.'s1 insightful analysis on a rapid response system failure draws attention to afferent limb system failures of medical emergency teams (METs). The article also serves to highlight several key quality improvement (QI) educational points. The authors demonstrate a thorough grasp of the literature concerning METs. The case description reveals a detailed investigation that is thorough enough to create a timeline of events. I applaud the literature review and construction of a timeline, as these represent the first several steps of a root‐cause analysisbut they are somewhat insufficient. More work can be done here.
Extending their line of inquiry may uncover specific system factors involved in the afferent limb failure. To further the analysis, careful interviews of all involved personnel (including patients, family members, and nurses) may help identify the factors that compromise afferent limbs of METs and thereby make necessary improvements, as in the innovative Josie King Safety Program at Johns Hopkins Hospital (Baltimore, MD). Prado et al.1 are extremely fortunate in that their institution has a monitoring system in place to track MET activations. A more ambitious, though potentially more fruitful project, would be to, examine previous afferent limb failures in an effort to identify systems factors that are more generalizable to other institutions.
The difficulties in obtaining data are 2‐fold: first in gathering the data, and second in extending the data beyond one's own institution. The very nature of QI data, eg, data that are locally obtained and relevant to a particular institution, hinders its generalizability. However, afferent limb failures are real and perhaps ubiquitous.2, 3 The challenge then, is to develop strategies that can improve the functioning of METs (both afferent and efferent limbs) regardless of the institution.
As afferent limbs of METs have been identified as a priority for future attention for the greatest benefit,2, 4 the process of analyzing root‐causes of systems failures seems to be analogous to identifying risk factors for a novel disease. Once identified, the appropriate risk‐factor modifications can be undertaken. Only by careful examination of the data can true, relevant factors be identified. For this reason, I feel that Prado et al.'s1 excellent work should be expanded upon and replicated in other institutions.
Should these types of QI projects become more amenable to extrapolation to other institutions, a predominant reporting format may be needed. The Standards for Quality Improvement Reporting Excellence (SQUIRE) guideline

In reponse to: Optimization of antiviral prescribing for influenza
We thank Dr. Aldaja for the comments on our work. We agree that delays in laboratory diagnosis, and the inability to identify influenza viral subtype may further undermine the low rates of appropriate prescription of oseltamivir noted in our study. Additionally, we also suspect that improved diagnostic and treatment practices for patients with seasonal influenza are likely to benefit patients if an influenza pandemic were to arise.

In response to: A quality conundrum: Well done but not enough—Quality improvement conundrums: Looking back before moving forward
If clinician‐quality improvers are to gain traction as academicians,1 their first objective should be to bring quality improvement (QI) sandly into the world of scientific method. We believe that Dr. Chakraborti's 2 pointsthat the reasons for afferent limb failure need to be more closely investigated, and that lessons learned from 1 hospital's rapid response system (RRS) may not generalize to other hospitalsreflect the immaturity of QI as a science. In clinical science, 3 well‐defined testing phases bring 1 homogeneous, rigorously tested product to market that is monitored in a fourth phase. While Dr. Chakraborti urges us to examine our afferent limb failures more closely, the monitoring and reporting strategies used in the Josie King Patient Safety Program2 resonate with the postmarketing surveillance of Phase IV trials.
Although necessary and valid, we believe that the majority of the QI conundrum of RRS lies in the lack of premarket, stepwise testing of QI products. QI initiatives are often promulgated before an appropriate evidence base has been established. This lack of scientific rigor has resulted in RRS with calling criteria that have poor operating characteristics,3 undetermined methods for achieving afferent success,4 and efferent response arms of varying sizes and compositions.5 Consequently, a heterogeneous group of RRS have produced equivocal outcomes6 and diminished the applicability of lessons learned across institutions.
Indeed, while it is important to ask, What do we do now?, it may be more informative to answer the question, How did we get here?

Menopause, vitamin D, and oral health
To the Editor: Buencamino and colleagues1 reviewed the association between menopause and periodontal disease. However, they did not mention the role of vitamin D status in this setting.
Vitamin D status is usually divided into three categories based on serum 25-hydroxyvitamin D levels: “deficient” (≤ 15 ng/mL), “insufficient” (15.1–29.9 ng/mL), and “sufficient” (≥ 30 ng/mL). Serum 25-hydroxyvitamin D levels have been decreasing significantly for more than a decade, and as a result, a majority of the US population has a vitamin D insufficiency.
In the third National Health and Nutrition Examination Survey (NHANES III), a large US population survey, a low serum 25-hydroxyvitamin D concentration was independently associated with periodontal disease.2 In particular, it was significantly associated with loss of alveolar attachment in persons older than 50 years of both sexes, independent of race or ethnicity; women in the highest 25-hydroxyvitamin D quintile had, on average, 0.26 mm (95% confidence interval 0.09–0.43 mm) less mean attachment loss than did women in the lowest quintile. Furthermore, in a randomized trial, supplementation with vitamin D (700 IU/day) plus calcium (500 mg/day) has been shown to significantly reduce tooth loss in older persons over a 3-year treatment period.3
Osteoporosis and periodontal disease share several risk factors, and it might be speculated that these pathologic conditions are biologically intertwined.4 The decreased bone mineral density of osteoporosis can lead to an altered trabecular pattern and more rapid alveolar bone resorption, thus predisposing to periodontal disease. On the other hand, periodontal infections can increase the systemic release of inflammatory cytokines, which accelerate systemic bone resorption. Indeed, vitamin D deficiency has been associated with a cytokine profile that favors greater inflammation (eg, higher levels of C-reactive protein and interleukin 6, and lower levels of interleukin 10), and vitamin D supplementation decreases circulating inflammatory markers.5 This might break the vicious circle of osteoporosis, periodontal disease development, and further systemic bone resorption.
Therefore, we suggest that menopausal women should maintain an adequate vitamin D status in order to prevent and treat osteoporosis-associated periodontal disease.
