  1. Hip Fracture & Vitamin D Update November 2007 Gregory Gahm, MD

  2. Informational Tidbits • 60-90% of NH residents fall annually • 20-50% of LTC pts who fall DIE the following year • 33% who have a hip fracture never walk again • From start (ambulance) to finish (therapy ends), the average direct cost of treating a hip fracture in Colorado is about $30,000(Taxpayers pay most of it…) • Falls and hip fractures account for a significant percentage of malpractice suits and formal complaints against NHs

  3. Statistics Review • RR = Relative Risk • CI = Confidence Interval • RR is reported with a Confidence Interval statistically calculated based on magnitude of measured difference, # of study subjects, time… • RRs w/ CIs: • < 1.0: Result less likely to happen w/ Intervention • > 1.0: Result more likely to happen w/ Intervention • When CI includes 1.0: Can’t tell • If CI does not include 1.0, there is a 95%chance the same result would occur no matter how many times you repeat the study

  4. Falls and Fractures Interventions shown to decrease falls in community-dwelling elderly: • Muscle strengthening / balance retraining [RR 0.80*; CI* 0.66-0.98] • 15 Week Tai Chi group exercise [RR 0.51; CI 0.36-0.73] - only for active participants; benefits disappeared when exercise stopped • Withdrawal of psychotropic medication [RR 0.34; CI 0.16-0.74] • Multidisciplinary, multifactorial, health/environment RF screening /intervention trials {No Rx changes} [RR 0.79; CI 0.67-0.94] • Same interventions in LTCFs are markedly less effective

  5. Hip Fractures and PPIs • Pts >50 yo on Proton Pump Inhibitors • (eg, Prilosec, Prevacid, Aciphex, Nexium, Omeprazole, Protonix) • 13,556 hip fracture cases compared to 135,000 matched controls in the UK • RR of hip fracture increased with dose, duration and age • >1 year: RR = 1.44[CI = 1.3-1.6] • High Dose*: RR = 2.65[CI = 1.8-3.9] *(>1.75x avg qd dose) JAMA, Dec 27, 06; Vol 296: 2947-53

  6. Clinical Trials of External Hip Protectors Early studies with < 50% compliance: • Lauritzen (Lancet, 1993) 31 hip fxs in 418 controls [7.5%] vs 8 in 247 [3.2%] in treatment group. • NONE on a pad protected hip. • Kannus (NEJM, 2000) 21 hip fxs / 1000 pt-yrs [protected] vs 46 in the control group. • 4 fxs on a pad protected hip. • Ekman (Lancet, 1997) 21 hip fxs during study period • NONE on a pad protected hip.

  7. Clinical Trials of EHPs • Wiener & Birge (02): 19 fractures / 310 patient-years on unprotected hips - vs - 1 fracture / 320 patient-years on protected hips • Pooled data from 6 major trials: • 3553 subjects • Hip fxs in 2.2% of those with EHPs vs 6.2% of control group • Average compliance rates estimated to be about 40% • NNTto prevent 1 fracture / year is  25-40 with 40% compliance or  10-12 with 85% compliance

  8. NH Chain National Hip Protector Study 14,000 patients in facilities were given the opportunity to wear hip protectors - 7000 chose NOT to wear them. - 7000 chose to wear hip protectors Compliance was estimated to be 55-70%

  9. NH Chain National Hip Protector Study At the end of 1 year / 3500 pt-years: In those NOT wearing Hip Protectors… 115 Fractures (= 33 Fractures per 1000 residents annually) In the Hip Protector Intention to Treat group… 45 Fractures(= 13 Fractures per 1000 residents annually) Only 3 were in patients wearing EHPs Comparing ‘Wearers’ to ‘NON-wearers’ –> 3 vs 42 Fxs or 0.8 vs 12 Fractures / 1000 Patient-Years

  10. The HIP PRO RCT Efficacy of a Hip Protector to Prevent Hip Fracture in NH Residents • 1042 NH Residents, Mean age 85 • Left or Right Pad Only • 8 month avg participation • Compliance checked 3x/wk: 60-80% avg Results: Same incidence of fractures on padded vs unpadded hips JAMA; July 25, 2007; Vol 298: 413-22

  11. The Rebuttal • The JAMA article used a Hip Protector that has not been available since 2003! • The study pad and the one that replaced it were tested using a drop weight system in 2004. The study pad absorbed 30% of peak force, the replacement 75-90% • Most brands currently available still absorb only 25-35% of peak force, which may not be adequate to prevent a fracture • Human volunteer fallers using the new pad in 2004 did > 400 falls without pain or hip injury • Fall reflex characteristics (the baby / ice argument)

  12. So, are the major brands of EHPs available equivalent? No. Brand makes a difference. • Some brands tested in RCTs have shown dramatic reductions in hip fractures (FallGard) or at least statistically significant decreases (HipSavers) • Some have shown NO difference or even MORE fractures (usu due to poor design, inadequate pad, or pad placement) • Many have never been studied in RCTs

  13. Evercare ColoradoHip Protector Study 3 Facilities chosen that historically [98-2001] had the highest number of hip fractures. There were16hip fractures among 200 patients in the previous 7 months (Annually, 27.5 hip fractures would be expected to occur in this group, a number that was consistent from 1998-2001) 180 of these patients were identified as being at highest risk and given Hip Protectors (FallGard) The 20 patients deemed to be at lowest risk for falls were excluded from the study

  14. Evercare Hip Protector Study There were 3 hip fractures among these 180 pts the following year… …none of them were wearing their hip protectors at the time of their fall / fracture PS. There were also 3 fractures among the 20 persons excluded from the study…

  15. Implementation Issues Lost Briefs • Mark them well / Inservice Staff Acceptance by Facilities • Significant financial savings from keeping census up and patients alive • Fewer Complaint Surveys / Law suits • Improved MDS data (better surveys?) • No F Tags for ‘acceptable’ noncompliance rates • SIGNIFICANT findings studies all had only 35-60% compliance Acceptance by Patients & Familes • Nonpharmacologic treatment that works • Families / patients appreciate the risk reduction in death, permanent disability, hospitalization / surgery, loss of Ambulation & Independent skills… Noncompliance • Takes about 2-6 weeks for patients to get used to them • Routine Checks + immediate feedback to nursing & CNAs • Assistance from families – use information sheets

  16. Ordering FallGard Hip Protectors FallGard 631 Alexandria Dr Naperville, IL 60565 800-828-0702 Fax 630-369-5219 www.fallgard.com Sizes: XS, S, M, L, XL, XXL, XXXL Order the “Sewn-In Pad” version

  17. Vitamin D: The Basics • Essential for adequate intestinal absorption of Ca++ • Vitamin D insufficiency: • Can compromise muscle strength & impair lower extremity function • Associated with Increased Arterial Calcification • Occurs in 75-85% of patients with Chronic Kidney Disease (Prevalence of CKD in NHs is likely >60-75%) • Leads to Increased PTH -–> Higher Bone Turnover

  18. Vitamin D: The Problem Most LTC residents have insufficient / deficient levels of Vitamin D –> 70-98% in recently published studies

  19. Vitamin D and FallsMeta-analysis of RCTs in elderly (n=1237) -> 700 IU D2 = Avg Dose Vitamin D reduced risk of falling by22% (OR 0.78; 95% CI (0.64-0.92) compared to Ca++ or placebo JAMA, April 28, 2004; Vol 291: 1999-2005

  20. Dosage of Vitamin D Needed to Reduce Falls • N=125 LTC residents • 5 months of D2 supplements 200, 400, 600 or 800 IU qd • 800 IU supplement was not enough to achieve “sufficient” Serum 25(OH) levels in 50% of those treated Units / day 25 (OH) Vit D ng/ml RR falls 0 24 +13 1.0 200 24+8 1.10 400 22+9 1.05 600 24+9 1.21 800 30+60.28* (.10-.75) JAGS 2007; 55:234

  21. Vitamin D2 vs D3 Most standard Ca++ combinations contain 200 IU of Vit D2 -> Available as 400 IU Caps & usu given 3 qd -> D2 is only  2/3 as effective in raising Vit D levels as D3 -> 200 U Vitamin D2 =~ 140 U D3 -> Daily rec for Vit D2 would be 1500 IU qd Vitamin D3 Caps of 50,000 & 5,000 units are available and can be given monthly (always with a meal) -> Give with meals that contain fats or oils to stimulate bile acids & improve absorption

  22. Vitamin D3 • Supplementation with 800-1200 IU qd of Vit D3 in seniors reduces both falls and fractures by 20-30% • Alternatively, give 50,000 IU q month of Vitamin D3 • Lower doses have much less effect & do not correlate with decreased fracture rates with or without Ca++ supplementation • 800 IU of Vitamin D3 qd undertreats 50% of pts • Current AMDA guideline: 1000 IU of Vitamin D3 qd

  23. Vitamin D: Resident Safety • Residents with Stage IV Kidney disease (GFR <15) may not benefit from getting Vitamin D3 • History of Kidney Stones is generally not a contraindication, but history must be reviewed carefully • Recent studies show that doses of 100,000 - 130,000 IU / mo did not lead to adverse effects • No need to test Vit D-25(OH) routinely! • Lab test is MUCH more expensive (circa $50) than years of treatment • Prevalence is high enough to assume >4 of 5 elderly patients are deficient • Treating pts who aren’t deficient is very unlikely to cause harm & may have benefits • Malabsorption syndromes may require higher doses & measurement of 25 (OH) Vit D levels to find effective dose

  24. Vit D Deficiency & Prostate Cancer • 14,916 men in Physicians' Health Study initially cancer-free • After 18 yrs of F/U, 1,066 subjects were identified with incident Prostate CA & compared their Vit D status with that of 1,618 cancer-free, age- and smoking-matched controls • Men with below-median levels of Vit D had a significantly higher risk of aggressive Prostate CA (OR 2.1) • Men with below-median levels of Vit D & the Vit D receptor polymorphism FokI ff had a higher risk of total and aggressive Prostate CA than those with above-median levels and the Ff or FF genotype (OR 1.9 & 2.5, respectively). 
 • Overall, 13-51% of the physicians in the study were Vit D deficient in the summer/fall & 36-77% were deficient in the winter/spring Li H, Stampfer MJ, Hollis JBW, Mucci LA, Gaziano JM, et al. (2007) A Prospective Study of Plasma Vitamin D Metabolites, Vitamin D Receptor Polymorphisms, and Prostate Cancer. PLoS Med 4(3): e103 doi:10.1371/journal.pmed.0040103

  25. Link Between Serum Vit D & Heart Disease Risk • Levels of serum 25-OH D & CVD risk examined in 15,088 individuals age >20 • 7,186 men / 7,902 women • versampling of blacks, Hispanics & individuals aged > 60 • Mean 25-OH D level = 30 ng/mL. Levels lower in women, older individuals, ethnic minorities, obese subjects & those with HTN or DM • OR of CVD comparing those w/ serum OH 25 D in lowest (<21) vs highest (>37) quartiles: – HTN: 1.30 – DM: 1.98 – Obesity: 2.28 – High serum triglyceride: 1.47 • Good safety at doses of 2000-3000 IU per day • Vit D level < 21 assoc w/ immunological abnormalities, HTN & CHF • Author emphasized that 2000 IU/day is more likely to achieve adequate blood levels of Vit D for prevention of CVD & that there is compelling evidence that it reduces inflammation, lowers renin & angiotensin, may lower BP or blood vessel proliferation and may improve insulin sensitivity! Norris, et al. Archives of Internal Medicine; June 11, 2007

  26. Calcium Ca++ should still be given at doses of 1000-1500 mg qd as multiple doses –> never more than 500-600 mg at a time because people can’t absorb more from a single dose May give Ca++ with or without Vit D, as safety profile shows that the additional D2 will not cause harm (Norris study recommended 2000 IU / d or 60,000 IU q mo)

  27. Conclusions • Falls are bad • Hip Fractures are worse • We can have an immediate & long term impact with very little cost or effort • Every patient should be on the equivalent of ±1000-1500 IU of Vitamin D3 daily, given most easily as: • 50,000 units monthly, or • 10,000 units (2 x 5000 u caps) weekly • Every patient possible should be in GOOD Hip Protectors (eg, FallGard) • Continue Ca++ supplements at 500 mg bid - tid

  28. Obtaining Vitamin D3 • OTC? I’m still researching this… • Biotech-Pharmacal • 50,000 IU capsule • NDC # 53191-362-01 (Product ID 362A) • Bottles of 100 by prescription only for $15 • 5000 IU capsule • NDC # 53191-244-50 (Product ID 2445000A) • Bottles of 250 by prescription only for$7.85 • Contact Brad Smith • 1-800-345-1199 • Fax: 479-443-5643 • Brad@bio-tech-pharm.com • Cardinal will drop ship the item, but you'll have to speak with a representative and tell them you need to have it "drop shipped from “Biotech-Pharmacal"
