Prevalence, Perceptions, and Patterns of Cannabis Use Among Cardiac Inpatients at a Tertiary-Care Hospital: A Cross-Sectional Survey.

Background: Cannabis use may adversely affect cardiovascular health. Patterns of use by cardiac patients are unknown. We evaluated the prevalence, perceptions, and patterns of cannabis use among cardiac inpatients. Methods: A consecutive cross-section of cardiac inpatients, hospitalized between November 2019 and May 2020, were surveyed in-person or via telephone. Descriptive statistics and logistic regression were used to examine the characteristics of cannabis use. Results: The prevalence of past-12-month cannabis use was 13.8% (95% confidence interval [CI]: 11.8%-16.0%). Characteristics independently associated with cannabis use were as follows: age < 64 years (< 44 years, odds ratio [OR] = 3.96 [95% CI: 1.65-9.53]; age 45-64 years, OR = 2.72 [95% CI: 1.65-4.47]); tobacco use in the previous 6 months (OR = 1.91 [95% CI: 1.18-3.07]); having a cannabis smoker in one's primary social group (OR = 4.17 [95% CI: 2.73-6.38]); and a history of a mental health diagnosis (OR = 1.82 [95% CI: 1.19-2.79]). Among those using cannabis, 70.5% reported smoking or vaping it; 47.2% reported daily use. Most did not know the tetrahydrocannabinol (THC; 71.6%) or cannabidiol (CBD; 83.3%) content of their cannabis, or the dose of cannabis in their edibles (66.7%). As defined by Canada's Lower Risk Cannabis Use Guidelines, 96.7% of cannabis users reported ≥ 1 higher-risk use behaviour (mean = 2.3, standard deviation = 1.2). Over 60% of patients expressed no intention to quit or reduce cannabis use in the next 6 months. Conclusions: Cannabis use appears prevalent among cardiac patients. Most users demonstrated higher-risk use behaviours and low intentions to quit. Further work is needed to understand the impacts of cannabis use on the cardiovascular system and to develop guidelines and educational tools relating to lower-risk use, for cardiac patients and providers.

Contexte: L'utilisation du cannabis peut nuire à la santé cardiovasculaire, mais les habitudes d'utilisation des patients atteints de troubles cardiaques ne sont pas connues. Nous avons évalué la prévalence, les perceptions et les habitudes d'utilisation du cannabis chez des patients hospitalisés présentant des troubles cardiaques. Méthodologie: Une analyse transversale a été réalisée en interrogeant en personne ou au téléphone des patients hospitalisés consécutivement entre novembre 2019 et mai 2020 et présentant des troubles cardiaques. Des statistiques descriptives et une régression logistique ont été utilisées pour examiner les caractéristiques liées à l'utilisation du cannabis. Résultats: La prévalence de l'utilisation du cannabis au cours des 12 mois précédents était de 13,8 % (intervalle de confiance [IC] à 95 % : 11,8 % à 16,0 %). Les caractéristiques indépendamment associées à l'utilisation du cannabis étaient les suivantes : âge < 64 ans (< 44 ans, rapport de cotes [RC] = 3,96 [IC à 95 % : 1,65 à 9,53]; âge de 45 à 64 ans, RC = 2,72 [IC à 95 % : 1,65 à 4,47]); tabagisme dans les six mois précédents (RC = 1,91 [IC à 95 % : 1,18 à 3,07]); présence d'un consommateur de cannabis au sein du cercle social principal (RC = 4,17 [IC à 95 % : 2,73 à 6,38]); et diagnostic antérieur lié à la santé mentale (RC = 1,82 [IC à 95 % : 1,19 à 2,79]). Parmi les utilisateurs de cannabis, 70,5 % d'entre eux ont rapporté qu'ils fumaient ou vapotaient et 47,2 % ont déclaré en consommer quotidiennement. La plupart ne connaissaient pas le contenu en tétrahydrocannabinol (THC; 71,6 %) ou en cannabidiol (CBD; 83,3 %) du cannabis consommé, ou la dose contenue dans les aliments à base de cannabis consommés (66,7 %). Au total, 96,7 % des utilisateurs de cannabis ont rapporté ≥ 1 comportement(s) à risque élevé (moyenne = 2,3, écart-type = 1,2) selon les Recommandations canadiennes pour l'usage du cannabis à moindre risque. Par ailleurs, plus de 60 % des patients n'ont exprimé aucune intention d'interrompre ou de diminuer leur consommation de cannabis au cours des six prochains mois. Conclusions: L'utilisation du cannabis semble courante chez les patients qui présentent des troubles cardiaques. La plupart des utilisateurs ont démontré des comportements à risque élevé, et une faible intention de mettre fin à leur consommation. D'autres études sont requises pour caractériser les répercussions de l'utilisation du cannabis sur l'appareil cardiovasculaire et élaborer des lignes directrices et des outils éducatifs à l'intention des patients atteints de troubles cardiaques et des professionnels de la santé en vue de favoriser un usage à moindre risque.

Nicotine replacement therapy 'gift cards' for hospital inpatients who smoke: a prospective before-and-after controlled pilot evaluation.

INTRODUCTION: A common barrier identified by individuals trying to quit smoking is the cost of cessation pharmacotherapies. The purpose of this evaluation was to: (1) Assess the feasibility of offering nicotine replacement therapy (NRT) 'gift cards' to hospitalised smokers for use posthospitalisation; and, (2) Estimate the effect of providing NRT gift cards on 6-month smoking abstinence. METHODS: A prospective, quasi-experimental, before-and-after controlled cohort design with random sampling was used to compare patients who had received the Ottawa Model for Smoking Cessation (OMSC) intervention ('control') with patients who received the OMSC plus a $C300 Quit Card ('QCI'), which they could use to purchase any brand or form of NRT from any Canadian pharmacy. RESULTS: 750 Quit Cards were distributed to the three participating hospitals of which 707 (94.3%) were distributed to patients. Of the cards received by patients, 532 (75.2%) were used to purchase NRT. A total of 272 participants completed evaluation surveys (148 control; 124 QCI).Point prevalence abstinence rates adjusted for misreporting among survey responders were 15.3% higher in the QCI group, compared with controls (44.4% vs 29.1%; OR 1.95, 1.18-3.21; p=0.009). Satisfaction was high among participants in both groups, and among staff delivering the QCI. QCI participants rated the intervention as high in terms of motivation, ease of use and helpfulness. CONCLUSIONS: The NRT gift card appears to be a feasible and effective smoking cessation tool that removes a primary barrier to the use of evidence-based smoking cessation pharmacotherapies, while motivating both patients and health providers.

Deprescribing Interventions by Palliative Care Clinical Pharmacists Surrounding Goals of Care Discussions.

Background: Palliative care (PC) pharmacists can play an important role in optimizing medications for patients with serious illnesses by aligning patients' goals with their treatment regimens. Objectives: The objectives of this study were to (1) quantify successful pharmacist deprescribing interventions incorporated in the hospital discharge plan and (2) describe deprescribing interventions by medication class, reason for discontinuation, and perception of patient/caregiver understanding and acceptance. Methods: This pilot study included 45 inpatient PC consultations and collected data on deprescribing interventions performed by PC clinical pharmacists in Maryland and Washington, D.C., U.S. Descriptive statistics were used to analyze outcomes. Results: Eighty-two percent of recommendations were successfully implemented during hospitalization and included in the discharge plan. Medication classes recommended for discontinuation included vitamins/supplements (20%), antidiabetics (13%), antiplatelets (10%), anticoagulants (10%), statins (10%), antihypertensives (7%), proton pump inhibitors/H2 blockers (7%), antibiotics (5%), dementia medications (1%), and antidepressants (1%). Top reasons for discontinuation included pill burden, unacceptable treatment burden, and potential harm outweighs potential benefit. Conclusions: Results of this study demonstrate PC pharmacists' deprescribing recommendations have a high rate of successful implementation by the primary inpatient care team.

Harnessing the epic electronic medical record to track indwelling ureteral stents in a pediatric population.

INTRODUCTION: Retention of indwelling ureteral stents due to loss to follow-up can result in significant harm to patients, often requiring multiple trips to the operating room. Despite widespread use of electronic medical records, there are few standardized options for urologists to track ureteral stents and no data on the rate of retained stents in a pediatric population. OBJECTIVE: This pilot quality improvement project aims to: 1) develop a simple process to track indwelling ureteral stents using the Epic electronic medical record and 2) determine the incidence of forgotten stents in a pediatric population. METHODS: We identified that operating room staff scan a barcode for ureteral stents at the time of surgery to log the stent as "Implanted" in the patient's medical record. The stent can later be marked as "Explanted" at the time of removal. A report was designed within Epic to identify all patients with a ureteral stent implanted from April 2014 to June 2019 at our hospital. We reviewed the records of patients whose stents had never been marked as "Explanted" to determine if any had a retained stent. A workflow was then designed to ensure staff would mark stents as "Explanted" at the time of removal and to periodically run the report within Epic to ensure that all patients with ureteral stents in place have appropriate follow-up. RESULTS: Our report identified 152 ureteral stents with a status of "Implanted". 3 patients did not have evidence of stent removal documented in their medical record. Follow up with these patients revealed stent removal at an outside location. DISCUSSION: Current approaches to stent tracking are laborious with limitations to adherence. The Epic software directly incorporates stent tracking into the individual patient chart allowing for easy implementation and follow up. Our study revealed no retained stents in our pediatric population. CONCLUSIONS: All patients with ureteral stents placed at a single institution over a 5-year period were easily identified using an automated Epic report. Through this report, we will prevent morbidity associated with stent retention. This technique could easily be implemented at other hospital systems that use Epic, and similar reporting tools could be designed within other electronic medical record systems. The incidence of ureteral stent retention in the pediatric population is likely significantly lower than for their adult counterparts.

The INITIATE trial protocol: a randomized controlled trial testing the effectiveness of a "quit card" intervention on long-term abstinence among tobacco smokers presenting to the emergency department.

BACKGROUND: Smoking cessation interventions implemented in emergency department (ED) settings have resulted in limited success, owing to factors such as lack of time, motivation, and incentives. A dynamic yet simple and effective approach that addresses the fast-paced nature of acute-care ED settings is needed. This study proposes a multi-center randomized controlled trial (RCT) to compare the effectiveness of an easy to deliver proactive, multi-component tobacco treatment intervention to usual care in the ED setting. METHODS: This will be a prospective four-site, single-blind, blinded-endpoint (PROBE) RCT. Participants will be recruited directly in the ED and will be approached strictly in order of arrival time. Those randomized to the Quit Card Intervention (QCI) group will receive a "quit kit" which will include: a "Quit Card" worth $300 that can be used at any Canadian pharmacy to purchase any form of nicotine replacement therapy (NRT); a self-help booklet; and proactive enrolment in 6 months of telephone follow-up counseling. The usual care (UC) group will receive a "quit kit" which will include a brochure for a local smoking cessation program. Quit kits for both groups will be delivered in opaque, sealed envelopes, and identical in size and weight so to conceal group allocation from the blinded research coordinator. Randomization will be stratified by site and by the Canadian Triage Acuity Scale (CTAS), a value assigned to each ED patient based on the severity of the condition. An equal number of quit kits will be prepared for each CTAS level. The primary outcome will be bio-chemically verified smoking abstinence at 26 weeks. Secondary outcomes include smoking behavior at weeks 4, 52, and 104 as well as mortality and health care utilization outcomes. Investigators, outcome assessors, and data analysts will be blinded to group allocation until after primary analyses are completed. It is hypothesized that the QCI group will have higher a abstinence rate, improved health outcomes, and decreased healthcare utilization. DISCUSSION: There are few examples of hospital EDs in Canada that systematically initiate tobacco cessation interventions for patients who smoke. Given the high smoking prevalence among ED patients and the relation of tobacco smoking to the majority of ambulatory care sensitive conditions, EDs are a missed opportunity in the initiation of tobacco treatment interventions. We have designed and will test an evidence-based tobacco treatment intervention that is simple and highly scalable. TRIAL REGISTRATION: ClinicalTrials.gov NCT04163081 .

Performance Obligations to Improve Delivery of Hospital-Initiated Smoking Cessation Interventions: A Before-and-After Evaluation.

INTRODUCTION: This study evaluated whether introducing performance obligations (a policy intervention) to service agreements between hospitals (n = 15) and their local health authority: (1) improved provision of an evidence-based tobacco cessation intervention (the "Ottawa Model" for Smoking Cessation) and (2) changed the quality of the cessation intervention being delivered. METHODS: Interrupted time series analysis was used to evaluate the change in the proportion of smoker patients provided the Ottawa Model 3 years before and 3 years after introducing the performance obligations. Changes in secondary outcomes related to program quality were described using mean differences, risk differences, and risk ratios, as appropriate. RESULTS: The proportion and number of patients provided the Ottawa Model doubled in the 3-year period following introduction of the new policy-from 3453 patients (33.7%) in the year before to 6840 patients (62.8%) in the final assessment year. This resulted in a signification slope change (+9.2%; 95% confidence interval [CI] 4.5%, 13.9%; p = .01) between the pre- and post-obligation assessment periods, signifying the policy had a positive impact on performance. Quality and effectiveness of the in-hospital intervention remained steady. CONCLUSIONS: Implementation of performance obligations by a healthcare funder increased delivery of an evidence-based smoking cessation intervention across multiple hospitals. Given the known health and economic impacts of smoking cessation interventions, health authorities and hospitals should consider pairing adoption of systematic interventions, like the Ottawa Model, with policy to enhance reach and impact. IMPLICATIONS: • The hospital-based Ottawa Model for Smoking Cessation (OMSC) intervention has been shown to increase smoking abstinence, while reducing mortality and healthcare utilization.• The uptake of systematic, evidence-based interventions, like the OMSC, by hospitals has been relatively low despite the known positive impacts.• The introduction of smoking cessation performance obligations by a healthcare funder resulted in more patients receiving an OMSC intervention while in hospital, with no corresponding change in intervention quality or effectiveness.• Healthcare funders and hospitals should consider pairing the adoption of effective, systematic interventions, like the OMSC, with policy to enhance reach and impact.

A novel "embryo-endometrial" adhesion model can potentially predict "receptive" or "non-receptive" endometrium.

OBJECTIVE: To establish a model of human implantation that responds to hormonal stimuli and can differentiate between endometrium from fertile women and those with idiopathic infertility. DESIGN: A trophoblast stem cell (trophectodermal) line (TSC; derived from human pre-implantation embryo) was used to form trophectodermal spheroids (TS). TS attachment to monolayers of endometrial epithelial cell lines or primary endometrial epithelial cells (pHEECs) was determined. SETTING: Independent Medical Research Institute with close clinical linkages INTERVENTIONS: Spheroid attachment and outgrowth was determined with added hormones (estradiol 17ß (E), E + medroxyprogesterone acetate (MPA) or E + MPA + human chorionic gonadotropin (hCG)). Spheroid attachment to E/MPA treated pHEEC prepared from fertile women or those with idiopathic infertility tested. MAIN OUTCOME MEASURE: Firmly attached spheroids counted after co-culture for 6 h. Outgrowth was determined by quantitation of area covered by spheroid after firm adhesion. RESULTS: Functional adhesion of TS to two endometrial epithelial cell lines, Ishikawa and ECC-1 cells, was hormonally responsive, with adhesion/outgrowth increased by E/MPA (ECC-1; p < 0.01, Ishikawa; p < 0.01) and E/MPA/hCG (ECC-1; p < 0.001, Ishikawa p < 0.01) versus E alone. The same pattern of hormone responsiveness was observed in pHEEC obtained from fertile women (E vs, E/MPA; p < 0.01, E vs. E/MPA/hCG; p < 0.001). TS adhered to 85% of pHEEC obtained from fertile women (11/13) and 11% of pHEEC obtained from women with unexplained infertility (2/18, p < 0.001). CONCLUSION: This new model of "embryo" implantation largely discriminates between endometrial epithelial cells obtained from fertile vs. infertile women based on adhesion; this holds potential as an in vitro "diagnostic" tool of endometrial infertility.

Getting to the Heart of the Matter: A Regional Survey of Current Hospice Practices Caring for Patients With Heart Failure Receiving Advanced Therapies.

BACKGROUND:: No guidelines exist regarding care for patients with advanced heart failure (HF) receiving hospice care while continuing advanced HF therapies such as left ventricular assist devices (LVADs) or continuous inotropes. OBJECTIVE:: We surveyed hospice providers in our tristate region to determine hospice demographics, current practices for care of patients with advanced HF, and perceived challenges of providing advanced HF therapies. DESIGN:: Cross-sectional survey of hospice clinical and administrative leaders. RESULTS:: Forty-six respondents representing 23 hospices completed the survey. Over half (27/46) held leadership administrative roles, and most (37/46) had more than 5 years of hospice experience. Although lack of experience and cost were cited as primary barriers to providing inotrope therapy in home hospice, about half of respondents (24/46) said they would manage inotropes. All participants said their respective hospices accept patients with implantable cardioverter-defibrillators; over half (28/46) said they accept patients with LVADs into hospice care. Lack of experience with LVADs was the most frequently cited barrier. Most participants were interested in training and support by an advanced HF program to facilitate hospice care of patients receiving these advanced therapies. General access to hospice services for patients with HF at their organization was considered adequate by 30 of 46 participants. Most (32/46) reported that referrals are made too late. CONCLUSIONS:: Hospice specialists reported widely varied practice experiences caring for patients with HF receiving advanced therapies, noted specific challenges for care of these patients, and expressed a desire for targeted HF education.

Safe and Appropriate Use of Methadone in Hospice and Palliative Care: Expert Consensus White Paper.

Methadone has several unique characteristics that make it an attractive option for pain relief in serious illness, but the safety of methadone has been called into question after reports of a disproportionate increase in opioid-induced deaths in recent years. The American Pain Society, College on Problems of Drug Dependence, and the Heart Rhythm Society collaborated to issue guidelines on best practices to maximize methadone safety and efficacy, but guidelines for the end-of-life scenario have not yet been developed. A panel of 15 interprofessional hospice and palliative care experts from the U.S. and Canada convened in February 2015 to evaluate the American Pain Society methadone recommendations for applicability in the hospice and palliative care setting. The goal was to develop guidelines for safe and effective management of methadone therapy in hospice and palliative care. This article represents the consensus opinion of the hospice and palliative care experts for methadone use at end of life, including guidance on appropriate candidates for methadone, detail in dosing, titration, and monitoring of patients' response to methadone therapy.

Effectiveness of integration of palliative medicine specialist services into the intensive care unit of a community teaching hospital.

BACKGROUND: Collaboration between palliative medicine and the intensive care unit (ICU) represents best practice and offers important benefits. However, achieving effective collaboration between these two specialties can be challenging. OBJECTIVE: Assess effectiveness of integrating palliative medicine specialists in the ICU. DESIGN: Retrospective chart review. RESULTS: Of 201 patients who qualified for palliative consultation using a palliative screening tool, 92 were referred and 109 were not referred for palliative medicine consultation. The number of screening criteria met was similar between the two groups. Palliative medicine consult volume increased significantly compared with preintegration (7.7±3.4 versus 4.4±2.8 consults per month, p=0.04). No significant difference in hospital mortality was found between the referred and unreferred groups (32/92 [35%] versus 26/109 [24%], p=0.09). ICU length of stay was significantly shorter in the referred group (7 versus 11 days, p<0.001). Referred patients were more frequently enrolled in hospice compared with unreferred patients (32/92 [37%] versus 3/109 [3%], p<0.001). ICU physicians referred patients significantly more often for dementia and ventilator withdrawal (13/16, p=0.003; 24/29, p<0.001, respectively) and significantly less often for ICU stay longer than 10 days (21 versus 49, p=0.001). CONCLUSIONS: Integrating palliative medicine specialists into intensive care was associated with a significant increase in use of palliative medicine services and a significant decrease in ICU length of stay for referred patients without a significant increase in mortality. The screening tool effectively identified patients at high risk of death. Given the high mortality rate of the unreferred patients, the criteria could be more widely adopted by ICU physicians to consider expanding palliative medicine referrals.

50 practical medication tips at end of life.

Patients with a life-limiting illness frequently experience pain and other symptoms. It is important to pay close attention when medication therapy is used to manage these symptoms. Occasionally, practitioners need to be creative in selecting, dosing, administering, and discontinuing medications at the end of life because of the patient's changing health care needs. This article offers practical end-of-life medication tips including, but not limited to, medication administration; guidance on how to increase and decrease doses; medication selection for difficult-to-treat patients; alternative dosage formulations; routes of medication administration; debridement medication regimens; and appropriate drug therapy selection.

Systematic review: conservative treatments for secondary lymphedema.

BACKGROUND: Several conservative (i.e., nonpharmacologic, nonsurgical) treatments exist for secondary lymphedema. The optimal treatment is unknown. We examined the effectiveness of conservative treatments for secondary lymphedema, as well as harms related to these treatments. METHODS: We searched MEDLINE®, EMBASE®, Cochrane Central Register of Controlled Trials®, AMED, and CINAHL from 1990 to January 19, 2010. We obtained English- and non-English-language randomized controlled trials or observational studies (with comparison groups) that reported primary effectiveness data on conservative treatments for secondary lymphedema. For English-language studies, we extracted data in tabular form and summarized the tables descriptively. For non-English-language studies, we summarized the results descriptively and discussed similarities with the English-language studies. RESULTS: Thirty-six English-language and eight non-English-language studies were included in the review. Most of these studies involved upper-limb lymphedema secondary to breast cancer. Despite lymphedema's chronicity, lengths of follow-up in most studies were under 6 months. Many trial reports contained inadequate descriptions of randomization, blinding, and methods to assess harms. Most observational studies did not control for confounding. Many studies showed that active treatments reduced the size of lymphatic limbs, although extensive between-study heterogeneity in areas such as treatment comparisons and protocols, and outcome measures, prevented us from assessing whether any one treatment was superior. This heterogeneity also precluded us from statistically pooling results. Harms were rare (< 1% incidence) and mostly minor (e.g., headache, arm pain). CONCLUSIONS: The literature contains no evidence to suggest the most effective treatment for secondary lymphedema. Harms are few and unlikely to cause major clinical problems.

Impact of standardized palliative care order set on end-of-life care in a community teaching hospital.

BACKGROUND: We evaluated use of medications and interventions in patients receiving a new standardized palliative care order set (PCOS) compared with patients receiving no palliative care orders and those with an order for comfort measures only (CMO), the largely ineffective method used at our institution before implementation of the order set. METHODS AND RESULTS: We conducted a retrospective chart review of all patients who died at our community teaching hospital between November 2006, 8 months after PCOS implementation, and May 2007. Of 106 patients in the study group, 31 (29%) were treated using the PCOS, 6 (6%) received the CMO order, and 69 (65%) did not receive either. Patients in the PCOS group had significantly more orders for every palliative medication (p ≤ 0.05). Opioids and anxiolytics were made available to every patient in the PCOS group. Most PCOS patients received orders for antiemetic, antipsychotic, antisecretion, and laxative medication during the end-of-life period. No CMO patients and few patients in the no palliative care orders group received orders for these medications. The PCOS and CMO group similarly limited nonpalliative interventions, whereas the nonpalliative group had relatively high use of these interventions until death. CONCLUSION: The palliative care order set implemented at our community teaching hospital significantly improved adherence to accepted palliative care treatment principles for patients at the end of life.

Fifty reasons to love your palliative care pharmacist.

Pharmacists have much to offer in caring for patients with an advanced illness. To celebrate the role of pharmacists in palliative care, we wanted to share 50 excellent reasons to love your pharmacist. This list was compiled by 3 pharmacists specializing in end-of-life care spanning from inpatient palliative care to home-based hospice. Our goal is to increase awareness among other hospice and palliative care practitioners by recognizing the skills pharmacists contribute in caring for patients at the end of life. We divided the list into categories: provision of pharmaceuticals, optimizing medication regimens, education and drug information, patient safety, and administration/formulary management.

Impact of writing "comfort measures only" orders in a community teaching hospital.

OBJECTIVES: We compared end-of-life care for patients with and without orders for "comfort measures only" (CMO) and evaluated whether standards for palliative medicine were met. DESIGN: We retrospectively reviewed the charts of 40 patients, 20 with and 20 without a CMO order, who died in our community teaching hospital from October 2003 through September 2004. Appropriate use of medications and interventions and documentation of symptoms and family consultation were examined. RESULTS: There were no significant demographic differences between the groups. Family meeting (18/20 versus 7/20, p < 0.001) and do-not-resuscitate/do-not-intubate (DNR/DNI) code status (20/20 versus 8/20; p < 0.001) occurred significantly more frequently in the CMO group. There were no other significant differences in prescribing medications or treatments. Notation of symptoms common at the end of life did not differ between the groups except for nausea/vomiting, which was more common in the non-CMO group. In the CMO group, opioids were significantly more available and antibiotics and routine laboratory work were significantly less common after the CMO order, but no other differences were observed. CONCLUSION: CMO orders alone were insufficient for redirecting changes in care at the end-of-life.

Complementary and alternative medicine in back pain utilization report.

OBJECTIVES: This systematic review was undertaken to evaluate which complementary and alternative medicine (CAM) therapies are being used for persons with back pain in the United States. DATA SOURCES: MEDLINE, CINHAHL, EMBASE, and Cochrane Central, and a variety of CAM specific databases were searched from 1990 to November 2007. A grey literature search was also undertaken, particularly for clinical practice guidelines (CPG) related to CAM. REVIEW METHODS: Standard systematic review methodology was employed. Eligibility criteria included English studies of adults with back pain, and a predefined list of CAM therapies. RESULTS: A total of 103 publications were evaluated; of these 29 did not present CAM therapy use stratified for back pain. There were a total of 65 utilization studies, 43 of which were American. Four publications evaluated the concurrent use of four or more CAM therapies and these suggest that chiropractic/manipulation is the most frequently used modality followed by massage and acupuncture. A limited number of publications evaluated utilization rates within multiple regions of the back and show that CAM was used least for treating the thoracic spine and most for the low back. However, rates of the use of massage were similar for neck and lower back regions. Concurrent use of different CAM or conventional therapies was not well reported. From 11 eligible CPG, only one (for electro-acupuncture) provided recommendations for frequency of use for low back pain of all acuity levels. Eighteen cost publications were reviewed and all but one publication (cost-effectiveness) were cost identification studies. There is limited information on the impact of insurance coverage on costs and utilization specific to back pain. CONCLUSIONS: There are a few studies evaluating the relative utilization of various CAM therapies for back pain. For those studies evaluating utilization of individual CAM therapies, the specific characteristics of the therapy, the providers, and the clinical presentation of the back pain patients were not adequately detailed; nor was the overlap with other CAM or conventional treatments.
