A Brief Measure of Fidelity for Mindfulness Programs: Development and Evaluation of the Concise Fidelity for Mindfulness-Based Interventions Tool.

Background: Mindfulness research and clinical programs are widespread, and it is important that mindfulness-based interventions are delivered with fidelity, or as intended, across settings. The MBI:TAC is a comprehensive system for assessing teacher competence, yet it can be complex to implement. A standardized, simple fidelity/engagement tool to address treatment delivery is needed. Objective: We describe the development, evaluation, and outcomes of a brief, practical tool for assessing fidelity and engagement in online mindfulness-based programs. The tool contains questions about session elements such as meditation guidance and group discussion, and questions about participant engagement and technology-based barriers to engagement. Methods: The fidelity rating tool was developed and tested in OPTIMUM, Optimizing Pain Treatment in Medical settings Using Mindfulness. The OPTIMUM study is a 3-site pragmatic randomized trial of group medical visits and adapted mindfulness-based stress reduction for primary care patients with chronic low back pain, delivered online. Two trained study personnel independently rated 26 recorded OPTIMUM sessions to determine inter-rater reliability of the Concise Fidelity for Mindfulness-Based Interventions (CoFi-MBI) tool. Trained raters also completed the CoFi-MBI for 105 sessions. Raters provided qualitative data via optional open text fields within the tool. Results: Inter-rater agreement was 77-100% for presence of key session components, and 69-88% for Likert ratings of participant engagement and challenges related to technology, with discrepancies only occurring within 2 categories: 'very much' and 'quite a bit'. Key session components occurred as intended in 94-100% of the 105 sessions, and participant engagement was rated as 'very much' or 'quite a bit' in 95% of the sessions. Qualitative analysis of rater comments revealed themes related to engagement challenges and technology failures. Conclusion: The CoFi-MBI provides a practical way to assess basic adherence to online delivery of mindfulness session elements, participant engagement, and extent of technology obstacles. Optional text can guide strategies to improve engagement and reduce technology barriers.

Yoga Versus Education for Veterans with Chronic Low Back Pain: a Randomized Controlled Trial.

BACKGROUND: Yoga is effective for chronic low back pain (cLBP) in civilians but understudied among Veterans. OBJECTIVE: Determine whether yoga is more effective than an educational book for improving disability and pain among Veterans with cLBP. DESIGN, SETTING, AND PARTICIPANTS: Veterans diagnosed with cLBP at a VA medical center enrolled in a randomized controlled trial from March to December of 2015. INTERVENTIONS: Twelve weekly hatha yoga classes or education using The Back Pain Helpbook. MEASURES: Co-primary outcomes were changes from baseline at 12 weeks in back-related disability on the modified Roland Morris Disability Questionnaire and pain on the Defense & Veterans Pain Rating Scale. Secondary outcomes were global improvement, patient satisfaction, pain medication use, and post-traumatic stress symptoms. An intention-to-treat approach was used in primary analyses. RESULTS: One hundred twenty Veterans (mean age, 55.5 [SD = 16.9]; 11 [9%] women; mean number of chronic conditions, 5.5) were randomized to yoga (n = 62) and education (n = 58). At 12 weeks, reductions in back-related disability in yoga (mean difference [MD] = - 3.50, 95% CI: - 5.03, - 1.97) were not significantly different than education (MD = - 2.55, 95% CI: - 4.10, - 0.99; between-group difference: - 0.95 [95% CI: - 3.14, 1.23], p = 0.39). For pain, there was no significant difference between yoga (MD = - 1.01, 95% CI: - 1.67, - 0.35) and education (MD = - 0.81, 95% CI: - 1.36, - 0.27; between-group difference: - 0.20, 95% CI: - 1.06, 0.66, p = 0.65). More yoga than education participants reported being very much or extremely improved (39% vs 19%, OR = 3.71, 95% CI: 1.37, 10.02, p = 0.01) and very satisfied with treatment (60% vs 31%, OR = 4.28, 95% CI: 1.70, 10.77, p = 0.002). No differences in pain medication use or post-traumatic stress symptoms were observed at 12 weeks. No serious adverse events were reported in either group. CONCLUSION: Twelve weekly yoga classes were not more effective than an education intervention for improving pain or disability outcomes among mostly older male Veterans with cLBP and multiple comorbid health conditions.

Characterizing Interprofessional Collaboration and Referral to Mindfulness-Based Stress Reduction Programs.

Background: In 2017, the American College of Physicians (ACP) designated Mindfulness-Based Stress Reduction (MBSR), an eight-week group program, as first-line non-pharmacological treatment for chronic low back pain. However, interprofessional collaboration between mindfulness instructors and Primary Care Providers (PCP) remains largely unknown. Objective: We developed a survey to assess communication between mindfulness instructors and PCPs, identify predictors of referral to MBSR, and determine areas where interventions could increase patient access to MBSR. Methods: The 25-question survey was sent via email to PCPs at the Division of General Internal Medicine, University of Pittsburgh, PA, the Piedmont Health Services Family Medicine Section, Chapel Hill, NC, the Boston Medical Center General Internal Medicine and Family Medicine Sections, Boston, MA, and the UMass Memorial Medical Center Family Medicine Section, Worcester, MA. We used descriptive statistics and logistic regression to analyze the data. Results: Among 118 eligible respondents, 85 (72.0%) were female PCPs, mean age was approximately 41.5±10.1, and the majority (65.2%) had been in medical practice ≤10 years. Of these PCPs, 83 (70.1%) reported familiarity with MBSR (95% CI: 62.1, 78.5), and 49 (59.0%) of them referred patients at least yearly. Of those who referred, 8 (16.3%) reported collaboration with mindfulness instructors. PCPs who were quite a bit or very much familiar with MBSR had 5.10 (1.10, 22.50) times the odds (P=.03), and those who were 50 years or younger had 3.30 times the odds (P=.04) of referring patients to MBSR. Frequency of PCPs' personal practice of mindfulness was not significantly associated with referrals (P=.30). Conclusion: This is the first study to assess interprofessional collaboration between mindfulness instructors and PCPs. Suggestions for a potential integrative health care model are included; further studies on methods to augment communication and education are warranted to improve the referral process and ultimately increase accessibility and utilization of mindfulness-based programs.

The design and methods of the OPTIMUM study: A multisite pragmatic randomized clinical trial of a telehealth group mindfulness program for persons with chronic low back pain.

Mindfulness-based stress reduction (MBSR) is an evidence-based non-pharmacological approach for chronic low back pain (cLBP), yet it is not readily available or reimbursable within primary care clinics. Primary care providers (PCPs) who wish to avoid prescribing opioids and other medications typically have few options for their cLBP patients. We present the protocol of a pragmatic clinical trial entitled OPTIMUM (Optimizing Pain Treatment In Medical settings Using Mindfulness). OPTIMUM is offered online via telehealth and includes medical group visits (MGV) with a PCP and a mindfulness meditation intervention modeled on MBSR for persons with cLBP. In diverse health-care settings in the US, such as a safety net hospital, federally qualified health centers, and a large academic health system, 450 patients will be assigned randomly to the MGV + MBSR or to usual PCP care alone. Participants will complete self-report surveys at baseline, following the 8-week program, and at 6- and 12-month follow-up. Health care utilization data will be obtained through electronic health records and via brief monthly surveys completed by participants. The primary outcome measure is the PEG (Pain, enjoyment, and general activity) at the 6-month follow-up. Additionally, we will assess psychological function, healthcare resource use, and opioid prescriptions. This trial, which is part of the NIH HEAL Initiative, has the potential to enhance primary care treatment of cLBP by combining PCP visits with a non-pharmacological treatment modeled on MBSR. Because it is offered online and integrated into primary care, it is expected to be scalable and accessible to underserved patients. Clinical Trials.gov: NCT04129450.

Risk Factors for Development of Hypocalcemia in Patients With Cancer Treated With Bone-Modifying Agents.

BACKGROUND: This retrospective analysis describes the prevalence of and risk factors associated with the development of hypocalcemia in patients with cancer receiving bone-modifying agents (BMAs) as supportive care. PATIENTS AND METHODS: Patients with cancer treated with an intravenous or subcutaneous BMA, including pamidronate, zoledronic acid, or denosumab, at a tertiary care/safety net hospital in 2005 through 2015 were included in this retrospective review. We reviewed the medical records for predictive clinical and laboratory parameters and for patient outcomes. RESULTS: A total of 835 patients with cancer received at least one dose of a BMA during the specified time frame; 205 patients (25%) developed hypocalcemia of CTCAE grade ≥1 within 8 weeks of BMA initiation, 18 of whom (8.8%) had grade ≥3, and 3 patients died as a result. Multivariate analysis showed that patients with hematologic malignancy (odds ratio [OR], 1.956; P=.025), bone metastases (OR, 2.443; P=.017), inpatient status (OR, 2.592; P<.001), and deficient baseline vitamin D levels (OR, 2.546; P<.023) were more likely to develop hypocalcemia. Hypercalcemia before BMA administration (OR, 0.474; P=.032) was protective. CONCLUSIONS: Certain patient populations, including those with hematologic malignancies and/or bone metastases, warrant closer monitoring of calcium levels while receiving BMAs because of the high rate of hypocalcemia. Low pretreatment vitamin D levels are associated with the development of hypocalcemia. These data support close monitoring of calcium levels in patients with cancer receiving BMAs, in addition to adequate repletion of vitamin D before initiation of BMAs when possible.

Yoga, Physical Therapy, or Education for Chronic Low Back Pain: A Randomized Noninferiority Trial.

BACKGROUND: Yoga is effective for mild to moderate chronic low back pain (cLBP), but its comparative effectiveness with physical therapy (PT) is unknown. Moreover, little is known about yoga's effectiveness in underserved patients with more severe functional disability and pain. OBJECTIVE: To determine whether yoga is noninferior to PT for cLBP. DESIGN: 12-week, single-blind, 3-group randomized noninferiority trial and subsequent 40-week maintenance phase. (ClinicalTrials.gov: NCT01343927). SETTING: Academic safety-net hospital and 7 affiliated community health centers. PARTICIPANTS: 320 predominantly low-income, racially diverse adults with nonspecific cLBP. INTERVENTION: Participants received 12 weekly yoga classes, 15 PT visits, or an educational book and newsletters. The maintenance phase compared yoga drop-in classes versus home practice and PT booster sessions versus home practice. MEASUREMENTS: Primary outcomes were back-related function, measured by the Roland Morris Disability Questionnaire (RMDQ), and pain, measured by an 11-point scale, at 12 weeks. Prespecified noninferiority margins were 1.5 (RMDQ) and 1.0 (pain). Secondary outcomes included pain medication use, global improvement, satisfaction with intervention, and health-related quality of life. RESULTS: One-sided 95% lower confidence limits were 0.83 (RMDQ) and 0.97 (pain), demonstrating noninferiority of yoga to PT. However, yoga was not superior to education for either outcome. Yoga and PT were similar for most secondary outcomes. Yoga and PT participants were 21 and 22 percentage points less likely, respectively, than education participants to use pain medication at 12 weeks. Improvements in yoga and PT groups were maintained at 1 year with no differences between maintenance strategies. Frequency of adverse events, mostly mild self-limited joint and back pain, did not differ between the yoga and PT groups. LIMITATIONS: Participants were not blinded to treatment assignment. The PT group had disproportionate loss to follow-up. CONCLUSION: A manualized yoga program for nonspecific cLBP was noninferior to PT for function and pain.

Yoga versus education for Veterans with chronic low back pain: study protocol for a randomized controlled trial.

BACKGROUND: Chronic low back pain is the most frequent pain condition in Veterans and causes substantial suffering, decreased functional capacity, and lower quality of life. Symptoms of post-traumatic stress, depression, and mild traumatic brain injury are highly prevalent in Veterans with back pain. Yoga for low back pain has been demonstrated to be effective for civilians in randomized controlled trials. However, it is unknown if results from previously published trials generalize to military populations. METHODS/DESIGN: This study is a parallel randomized controlled trial comparing yoga to education for 120 Veterans with chronic low back pain. Participants are Veterans ≥18 years old with low back pain present on at least half the days in the past six months and a self-reported average pain intensity in the previous week of ≥4 on a 0-10 scale. The 24-week study has an initial 12-week intervention period, where participants are randomized equally into (1) a standardized weekly group yoga class with home practice or (2) education delivered with a self-care book. Primary outcome measures are change at 12 weeks in low back pain intensity measured by the Defense and Veterans Pain Rating Scale (0-10) and back-related function using the 23-point Roland Morris Disability Questionnaire. In the subsequent 12-week follow-up period, yoga participants are encouraged to continue home yoga practice and education participants continue following recommendations from the book. Qualitative interviews with Veterans in the yoga group and their partners explore the impact of chronic low back pain and yoga on family relationships. We also assess cost-effectiveness from three perspectives: the Veteran, the Veterans Health Administration, and society using electronic medical records, self-reported cost data, and study records. DISCUSSION: This study will help determine if yoga can become an effective treatment for Veterans with chronic low back pain and psychological comorbidities.

Coagulase-negative staphylococcal bloodstream infections: Does vancomycin remain appropriate empiric therapy?

OBJECTIVES: It is unknown if vancomycin minimal inhibitory concentrations (MICs) have increased in coagulase-negative staphylococci (CoNS) or whether vancomycin remains appropriate empiric therapy. METHODS: We performed a retrospective study at a single tertiary care center over 8 years. Adult inpatients with ≥2 positive blood cultures for CoNS within a 48-h period were eligible. Susceptibilities were performed by automated broth based-microdilution. Changes in antimicrobial susceptibility were analyzed using logistic regression. The clinical characteristics and outcomes of patients with bloodstream infections (BSI) were compared by MIC. RESULTS: Of 308 episodes of possible CoNS bacteremia, the vancomycin MIC was ≤1 µg/mL in 80 (26%) isolates, 2 µg/mL in 223 (72.4%) isolates and 4 µg/mL in 5 (1.6%) isolates. No isolates were resistant. We observed an 11-fold increased chance of having an isolate with a vancomycin MIC ≤1 µg/mL in 2009-2011 compared with 2004-2008 (OR 10.8, 95% CI 6.0-19.5, p < 0.05). In 152 patients with BSI, the median days of bacteremia, hospital mortality and readmissions at 30 days were similar in BSI caused by isolates with high vancomycin MICs (2-4 µg/mL) and low vancomycin MICs (≤1 µg/mL). CONCLUSIONS: We conclude vancomycin is still appropriate empiric therapy for CoNS BSIs. CoNS vancomycin MICs decreased over the study period despite widespread use of vancomycin.

Preference and Expectation for Treatment Assignment in a Randomized Controlled Trial of Once- vs Twice-weekly Yoga for Chronic Low Back Pain.

BACKGROUND: In studies involving nonpharmacological complementary and alternative medicine interventions, participant blinding is very difficult. Participant expectations may affect perceived benefit of therapy. In studies of yoga as treatment for chronic low back pain, little is known about the relationship between patient expectations and preferences on outcomes. This study was designed to identify baseline predictors of preference and to determine if expectations and preferences for different doses of yoga affect back-related function and low back pain intensity. METHODS: This was a secondary data analysis of a 12-week randomized controlled trial comparing once-weekly vs twice-weekly yoga for treatment of chronic low back pain in 93 adults from a predominantly low-income minority population. At baseline, participants were asked about back function, back pain, treatment expectations, and treatment preferences. We created a variable "concordance" to describe the matching of participant preference to randomized treatment. Our outcome variables were change in back function and pain intensity after 12 weeks of yoga instruction. We performed logistic regression to identify predictors of preference for once- or twice-weekly yoga instruction. We created linear regression models to identify independent associations between expectations, preference, concordance, and outcomes. RESULTS: Worse back function at baseline was associated with 20% higher odds of preferring twice-weekly yoga (OR 1.2, CI 1.1, 1.3). Individuals with higher expectation scores for twice-weekly yoga had 90% higher odds of preferring twice-weekly vs once-weekly yoga (OR 1.9, CI 1.3, 2.7). Individuals with higher expectation scores for once-weekly yoga had 40% less odds of preferring twice-weekly yoga (OR 0.6, CI 0.5, 0.9). After controlling for baseline characteristics, we found no statistically significant relationship between treatment outcomes, preference, expectation scores, or concordance. CONCLUSION: In a population of predominantly low-income minority participants with chronic low back pain, worse back function was associated with preference for more frequent yoga classes. Those who preferred more yoga classes had higher expectations for those classes. Twelve-week change in back pain intensity and back function were not affected by dosing preference, expectation score, or concordance. More research is needed to better measure and quantify preference, expectations, and their relationship to outcomes in yoga research.

Antecedentes: En estudios que incluyen intervenciones complementarias no farmacológicas y de medicina alternativa es muy difícil realizar estas de manera ciega para los participantes. Las expectativas de los participantes pueden afectar el beneficio percibido de la terapia. En estudios del yoga como tratamiento del dolor lumbar crónico, se sabe poco de la relación entre las expectativas del paciente y las preferencias sobre los resultados. Este estudio se diseñó para identificar los predictores iniciales de preferencia y para determinar si las expectativas y preferencias para dosis diferentes de yoga afectaban la funcionalidad relativa a la espalda y la intensidad de dolor lumbar.Métodos: Este fue un análisis de datos secundarios de un ensayo aleatorio controlado de 12 semanas que comparó yoga una vez a la semana frente a dos veces a la semana para el tratamiento del dolor lumbar crónico en 93 adultos de una población minoritaria predominantemente de ingresos bajos. En el momento inicial, se les preguntó a los participantes sobre el dolor y la funcionalidad de sus espaldas, las expectativas del tratamiento y las preferencias del mismo. Creamos una "concordancia" variable para describir la correspondencia entre las preferencias del paciente y el tratamiento aleatorizado. Nuestras variables de resultados fueron el cambio de la funcionalidad de la espalda y la intensidad del dolor después de 12 semanas de sesiones de yoga. Realizamos una regresión logística para identificar los predictores de preferencias para las sesiones semanales o bisemanales de yoga. Creamos modelos de regresión lineal para identificar las asociaciones independientes entre expectativas, preferencias, concordancia y resultados.Resultados: Una peor funcionalidad de la espalda en el inicio se asoció con un 20% de mayor probabilidad de preferir yoga dos veces a la semana (TP 1,2, IC 1,1, 1,3). Los individuos con mayores escalas de expectativas de yoga dos veces a la semana tuvieron un 90% más de probabilidades de preferir yoga dos veces a la semana que una vez a la semana (TP 1,9, IC 1,3, 2,7). Los individuos con mayores escalas de expectativas de yoga una vez a la semana tuvieron un 40% menos de probabilidades de preferir yoga dos veces a la semana (TP 0,6, IC 0,5, 0,9). Después de controlar las características iniciales, no hallamos relación estadísticamente significativa entre los resultados del tratamiento, preferencias, escalas de expectativas o concordancia.Conclusión: En una población de participantes de minorías predominantemente con bajos ingresos con dolor lumbar crónico, se asoció una peor funcionalidad de la espalda con la preferencia por una mayor frecuencia de clases de yoga. Aquellos que prefirieron más clases de yoga tenían más expectativas para esas clases. El cambio de doce semanas en la intensidad del dolor de espalda y la funcionalidad de la misma no se vio afectado por la preferencia de dosis, escala de expectativas o concordancia. Se necesita realizar más investigaciones para medir mejor y cuantificar las preferencias, las expectativas y su relación con los resultados en la investigación del yoga.

Participant Characteristics Associated with Symptomatic Improvement from Yoga for Chronic Low Back Pain.

CONTEXT: Studies suggest that yoga is effective for moderate to severe chronic low back pain (cLBP) in diverse predominantly lower socioeconomic status populations. However, little is known about factors associated with benefit from the yoga intervention. OBJECTIVE: Identify factors at baseline independently associated with greater efficacy among participants in a study of yoga for cLBP. DESIGN: From September-December 2011, a 12-week randomized dosing trial was conducted comparing weekly vs. twice-weekly 75-minute hatha yoga classes for 95 predominantly low-income minority adults with nonspecific cLBP. Participant characteristics collected at baseline were used to determine factors beyond treatment assignment (reported in the initial study) that predicted outcome. We used bivariate testing to identify baseline characteristics associated with improvement in function and pain, and included select factors in a multivariate linear regression. SETTING: Recruitment and classes occurred in an academic safety-net hospital and five affiliated community health centers in Boston, Massachusetts. PARTICIPANTS: Ninety-five adults with nonspecific cLBP, ages ranging from 20-64 (mean 48) years; 72 women and 23 men. OUTCOME MEASURES: Primary outcomes were changes in back-related function (modified Roland-Morris Disability Questionnaire, RMDQ; 0-23) and mean low back pain intensity (0-10) in the previous week, from baseline to week 12. RESULTS: Adjusting for group assignment, baseline RMDQ, age, and gender, foreign nationality and lower baseline SF36 physical component score (PCS) were independently associated with improvement in RMDQ. Greater than high school education level, cLBP less than 1 year, and lower baseline SF36 PCS were independently associated with improvement in pain intensity. Other demographics including race, income, gender, BMI, and use of pain medications were not associated with either outcome. CONCLUSIONS: Poor physical health at baseline is associated with greater improvement from yoga in back-related function and pain. Race, income, and body mass index do not affect the potential for a person with low back pain to experience benefit from yoga.

Inter-method reliability of paper surveys and computer assisted telephone interviews in a randomized controlled trial of yoga for low back pain.

BACKGROUND: Little is known about the reliability of different methods of survey administration in low back pain trials. This analysis was designed to determine the reliability of responses to self-administered paper surveys compared to computer assisted telephone interviews (CATI) for the primary outcomes of pain intensity and back-related function, and secondary outcomes of patient satisfaction, SF-36, and global improvement among participants enrolled in a study of yoga for chronic low back pain. RESULTS: Pain intensity, back-related function, and both physical and mental health components of the SF-36 showed excellent reliability at all three time points; ICC scores ranged from 0.82 to 0.98. Pain medication use showed good reliability; kappa statistics ranged from 0.68 to 0.78. Patient satisfaction had moderate to excellent reliability; ICC scores ranged from 0.40 to 0.86. Global improvement showed poor reliability at 6 weeks (ICC = 0.24) and 12 weeks (ICC = 0.10). CONCLUSION: CATI shows excellent reliability for primary outcomes and at least some secondary outcomes when compared to self-administered paper surveys in a low back pain yoga trial. Having two reliable options for data collection may be helpful to increase response rates for core outcomes in back pain trials. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01761617.

Yoga vs. physical therapy vs. education for chronic low back pain in predominantly minority populations: study protocol for a randomized controlled trial.

BACKGROUND: Chronic low back pain causes substantial morbidity and cost to society while disproportionately impacting low-income and minority adults. Several randomized controlled trials show yoga is an effective treatment. However, the comparative effectiveness of yoga and physical therapy, a common mainstream treatment for chronic low back pain, is unknown. METHODS/DESIGN: This is a randomized controlled trial for 320 predominantly low-income minority adults with chronic low back pain, comparing yoga, physical therapy, and education. Inclusion criteria are adults 18-64 years old with non-specific low back pain lasting ≥ 12 weeks and a self-reported average pain intensity of ≥ 4 on a 0-10 scale. Recruitment takes place at Boston Medical Center, an urban academic safety-net hospital and seven federally qualified community health centers located in diverse neighborhoods. The 52-week study has an initial 12-week Treatment Phase where participants are randomized in a 2:2:1 ratio into i) a standardized weekly hatha yoga class supplemented by home practice; ii) a standardized evidence-based exercise therapy protocol adapted from the Treatment Based Classification method, individually delivered by a physical therapist and supplemented by home practice; and iii) education delivered through a self-care book. Co-primary outcome measures are 12-week pain intensity measured on an 11-point numerical rating scale and back-specific function measured using the modified Roland Morris Disability Questionnaire. In the subsequent 40-week Maintenance Phase, yoga participants are re-randomized in a 1:1 ratio to either structured maintenance yoga classes or home practice only. Physical therapy participants are similarly re-randomized to either five booster sessions or home practice only. Education participants continue to follow recommendations of educational materials. We will also assess cost effectiveness from the perspectives of the individual, insurers, and society using claims databases, electronic medical records, self-report cost data, and study records. Qualitative data from interviews will add subjective detail to complement quantitative data. TRIAL REGISTRATION: This trial is registered in ClinicalTrials.gov, with the ID number: NCT01343927.

Comparing Once- versus Twice-Weekly Yoga Classes for Chronic Low Back Pain in Predominantly Low Income Minorities: A Randomized Dosing Trial.

Background. Previous studies have demonstrated that once-weekly yoga classes are effective for chronic low back pain (cLBP) in white adults with high socioeconomic status. The comparative effectiveness of twice-weekly classes and generalizability to racially diverse low income populations are unknown. Methods. We conducted a 12-week randomized, parallel-group, dosing trial for 95 adults recruited from an urban safety-net hospital and five community health centers comparing once-weekly (n = 49) versus twice-weekly (n = 46) standardized yoga classes supplemented by home practice. Primary outcomes were change from baseline to 12 weeks in pain (11-point scale) and back-related function (23-point modified Roland-Morris Disability Questionnaire). Results. 82% of participants were nonwhite; 77% had annual household incomes <$40,000. The sample's baseline mean pain intensity [6.9 (SD 1.6)] and function [13.7 (SD 5.0)] reflected moderate to severe back pain and impairment. Pain and back-related function improved within both groups (P < 0.001). However, there were no differences between once-weekly and twice-weekly groups for pain reduction [-2.1 (95% CI -2.9, -1.3) versus -2.4 (95% CI -3.1, -1.8), P = 0.62] or back-related function [-5.1 (95% CI -7.0, -3.2) versus -4.9 (95% CI -6.5, -3.3), P = 0.83]. Conclusions. Twelve weeks of once-weekly or twice-weekly yoga classes were similarly effective for predominantly low income minority adults with moderate to severe chronic low back pain. This trial is registered with ClinicalTrials.gov NCT01761617.

The effect of Reiki on work-related stress of the registered nurse.

PURPOSE: The Reiki Master Teacher group at a large academic, urban medical center studied the effects of Reiki on work-related stress in Registered Nurse Reiki I class participants. Research suggests that work-related stress is an influential factor in nursing burn out and retention. Reiki, an ancient form of Oriental "energy work" or healing, has been found to decrease stress. METHODS: The Perceived Stress Scale tool was administered prior to the Reiki I class and after three weeks of practicing self-Reiki. FINDINGS: Seventeen participants returned follow-up data. Results indicated that practicing Reiki more often resulted in reduced perceived stress levels. CONCLUSIONS: Data from this small pilot study supports educating nurses about Reiki practice to decrease work-related stress.

A higher dose of vitamin d reduces the risk of falls in nursing home residents: a randomized, multiple-dose study.

OBJECTIVES: To determine the effect of four vitamin D supplement doses on falls risk in elderly nursing home residents. DESIGN: Secondary data analysis of a previously conducted randomized clinical trial. SETTING: Seven hundred twenty-five-bed long-term care facility. PARTICIPANTS: One hundred twenty-four nursing home residents (average age 89). INTERVENTION: Participants were randomly assigned to receive one of four vitamin D supplement doses (200 IU, 400 IU, 600 IU, or 800 IU) or placebo daily for 5 months. MEASUREMENTS: Number of fallers and number of falls assessed using facility incident tracking database. RESULTS: Over the 5-month study period, the proportion of participants with falls was 44% in the placebo group (11/25), 58% (15/26) in the 200 IU group, 60% (15/25) in the 400 IU group, 60% (15/25) in the 600 IU group, and 20% (5/23) in the 800 IU group. Participants in the 800 IU group had a 72% lower adjusted-incidence rate ratio of falls than those taking placebo over the 5 months (rate ratio=0.28; 95% confidence interval=0.11-0.75). No significant differences were observed for the adjusted fall rates compared to placebo in any of the other supplement groups. CONCLUSION: Nursing home residents in the highest vitamin D group (800 IU) had a lower number of fallers and a lower incidence rate of falls over 5 months than those taking lower doses. Adequate vitamin D supplementation in elderly nursing home residents could reduce the number of falls experienced by this high falls risk group.
