Physician attitudes and beliefs about use of morphine for cancer pain.

The recent literature asserts that mistaken physician beliefs and attitudes are critical barriers to adequate cancer pain relief. To determine the prevalence of 12 proposed myths or misconceptions about morphine use in cancer pain management (CPM), we surveyed all physicians engaged in direct patient care in Duluth, Minnesota (N = 243). A 62% response was obtained. Many physicians misunderstood concepts of morphine tolerance, both to analgesia (51%) and to side effects (39%). Many were unaware of the use of adjuvant analgesics (29%), efficacy of oral morphine (27%), and nonexistent risk of addiction in CPM (20%). Analysis of result by physician age and specialy groups confirmed significant levels of misunderstanding in all subsets. Strategies to change physician attitudes and beliefs regarding morphine in CPM should focus on tolerance concepts, dosing schemes, safety, efficacy, lack of addictive risk, use of drug combinations, and the fact that cancer pain can be relieved.

Physician knowledge and attitudes about cancer pain management: A survey from the Minnesota cancer pain project

The purposes of the study were to determine the knowledge and attitudes about cancer pain management (CPM) among practicing physicians in six Minnesota communities and to determine the physician-related barriers to optimal CPM. Eligible community physicians were surveyed by telephone. The study analyzed responses of 145 physicians (response rate, 87%). The majority of the physicians were primary care specialists (73%). Significant knowledge deficits were identified in nine of 14 CPM principles, but inappropriate attitudes were found in only two of nine CPM concepts. Medical specialty had the strongest influence on knowledge and attitudes, with primary care physicians having significantly better outcomes than surgeons or medical subspecialists. Effective education strategies must address knowledge deficits, attitudes, and motivations of the relevant peer group influencing physicians, as well as those of individual physicians. The Minnesota Cancer Pain Project is testing strategies to enhance CPM by physicians and improve patient outcomes.

Chronic use of opioid medications before and after bariatric surgery.

IMPORTANCE Obesity is associated with chronic noncancer pain. It is not known if opioid use for chronic pain in obese individuals undergoing bariatric surgery is reduced. OBJECTIVES To determine opioid use following bariatric surgery in patients using opioids chronically for pain control prior to their surgery and to determine the effect of preoperative depression, chronic pain, or postoperative changes in body mass index (BMI) on changes in postoperative chronic opioid use. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study in a distributed health network (10 demographically and geographically varied US health care systems) of 11,719 individuals aged 21 years and older, who had undergone bariatric surgery between 2005 and 2009, and were assessed 1 year before and after surgery, with latest follow-up by December 31, 2010. MAIN OUTCOMES AND MEASURES Opioid use, measured as morphine equivalents 1 year before and 1 year after surgery, excluding the first 30 postoperative days. Chronic opioid use is defined as 10 or more opioid dispensings over 90 or more days or as dispensings of at least a 120-day supply of opioids during the year prior to surgery. RESULTS Before surgery, 8% (95% CI, 7%-8%; n = 933) of bariatric patients were chronic opioid users. Of these individuals, 77% (95% CI, 75%-80%; n = 723) continued chronic opioid use in the year following surgery. Mean daily morphine equivalents for the 933 bariatric patients who were chronic opioid users before surgery were 45.0 mg (95% CI, 40.0-50.1) preoperatively and 51.9 mg (95% CI, 46.0-57.8) postoperatively (P < .001). For this group with chronic opiate use prior to surgery, change in morphine equivalents before vs after surgery did not differ between individuals with loss of more than 50% excess BMI vs those with 50% or less (>50% BMI loss: adjusted incidence rate ratio [adjusted IRR, 1.17; 95% CI, 1.07-1.28] vs ≤50% BMI loss [adjusted IRR, 1.03; 95% CI, 0.93-1.14] model interaction, P = .06). In other subgroup analyses of preoperative chronic opioid users, changes in morphine equivalents before vs after surgery did not differ between those with or without preoperative diagnosis of depression or chronic pain (depression only [n = 75; IRR, 1.08; 95% CI, 0.90-1.30]; chronic pain only [n = 440; IRR, 1.17; 95% CI, 1.08-1.27]; both depression and chronic pain [n = 226; IRR, 1.11; 95% CI, 0.96-1.28]; neither depression nor chronic pain [n = 192; IRR, 1.22; 95% CI, 0.98-1.51); and P values for model interactions when compared with neither were P = .42 for depression, P = .76 for pain, and P = .48 for both. CONCLUSIONS AND RELEVANCE In this cohort of patients who underwent bariatric surgery, 77% of patients who were chronic opioid users before surgery continued chronic opioid use in the year following surgery, and the amount of chronic opioid use was greater postoperatively than preoperatively. These findings suggest the need for better pain management in these patients following surgery.

Educating Generalist Physicians about Chronic Pain: Live Experts and Online Education Can Provide Durable Benefits

OBJECTIVE Determine whether lectures by national experts and a publicly available online program with similar educational objectives can improve knowledge, attitudes, and beliefs (KAB) important to chronic pain management. DESIGN A pretest-posttest randomized design with two active educational interventions in two different physician groups and a third physician group that received live education on a different topic to control for outside influences, including retesting effects, on our evaluation. PARTICIPANTS A total of 136 community-based primary care physicians met eligibility criteria. All physicians attended the educational program to which they were assigned. Ninety-five physicians (70%) provided complete data for evaluation. MEASUREMENTS Physician responses to a standardized 50-item pain management KAB survey before, immediately after, and 3 months following the interventions. RESULTS The study groups and the 41 physicians not providing outcomes information were similar with respect to age, sex, race, percent engaged in primary care, and number of patients seen per week. Physician survey scores improved immediately following both pain education programs (live: 138.0-->150.6, P < 0.001; online: 143.6-->150.4, P = 0.007), but did not change appreciably in the control group (139.2-->142.5, P > 0.05). Findings persisted at 3 months. Satisfaction measures were high (4.00-4.72 on 1-5 scale) and not significantly different (P = 0.072-0.893) between groups. CONCLUSIONS When used under similar conditions, national speakers and a publicly available online CME program were associated with improved pain management KAB in physicians. The benefits lasted for 3 months. These findings support the continued use of these pain education strategies.

The Minnesota cancer pain project: Design, methods, and education strategies

The Minnesota Cancer Pain Project (MCPP) is a community-based research project to test various innovative education strategies for improving cancer pain management (CPM) in Minnesota. The main hypothesis is that community-based, multidisciplinary and integrated education programs can improve CPM and change knowledge, attitudes, and behaviors regarding CPM in cancer patients, their families, and community physicians and nurses. The specific aim of the MCPP is to demonstrate effective methods to improve CPM in communities. The MCPP design is a randomized trial with before- and after-intervention assessments of cancer pain and CPM knowledge, attitudes, and behaviors among cancer patients and their families, physicians, and nurses. The unit of randomization and study is the community, with six Minnesota communities participating in the MCPP. This paper describes the hypotheses, design, methods, and education strategies of the MCPP. Baseline data from the participating communities and the cancer patient sample are reported.

Physician acquisition of cancer pain management knowledge

Insufficient physician education in cancer pain management (CPM) is one of the major factors contributing to inadequate pain relief of cancer patients throughout the world. A survey of all physicians in direct patient care in Duluth, MN, (N = 243) was conducted to determine where they learned about CPM and how they would like to further their knowledge. Responses from 150 physicians (62%) have been analyzed, especially focusing on physician age and specialty. Statistically significant differences (p less than 0.001) document that residency training programs have been including CPM in their curricula since 1978 and that medical schools have not. Additional significant sources of CPM have been consultations with expert physicians, conferences and the literature. When asked how they would like to learn more about CPM, 84% of all physicians indicated that local conferences would be most effective. Physicians in various specialties indicated their differing preferences, too. This study suggests that improvements in CPM can occur through these mechanisms.

Two hospice quality of life surveys: A comparison

This study’s objective tested the utility of two quality of life (QOL) forms in a hospice setting. The compared forms were the McGill Quality of Life Questionnaire (MQOL) and the Hospice Quality of Life Index-Revised (HQLI). Using a crossover design, hospice nurses first administered one survey to eligible patients and then, in the study’s second phase, administered the other survey to newly enrolled eligible patients. Nurses were interviewed regarding each form and possible changes in patient care that were made due to the assessment. Hospice care plans were reviewed looking for specific changes as a result of the surveys. The results showed that the QOL assessments were useful for the nurses in planning the care of the hospice patients and that the MQOL was preferred by the nurses over the HQLI.

Chronic opioid use emerging after bariatric surgery.

Little is known about opioid use after bariatric surgery among patients who did not use opioids chronically before surgery. Our purpose was to determine opioid use the year after bariatric surgery among patients who did not use opioids chronically pre‐surgery and to identify pre‐surgery characteristics associated with chronic opioid use after surgery.

Pharmacologic management of cancer pain in rural Minnesota

Use of analgesic medications for cancer pain was assessed in six Minnesota communities. In our survey, cancer patients were treated primarily by family practice physicians. Approximately 70% were given one or more analgesics; 84% received a nonsteroidal antiinflammatory drug and 73% received an opioid. Most patients given an antiinflammatory drug received less than the maximal recommended dose for the drug. The most common opioid for cancer pain was oral morphine. Approximately 40% of the patients treated with opioids took the drug only when needed; the remainder took the drug around-the-clock, with or without additional opioids for breakthrough pain. Only 14% of patients who received analgesics received a coanalgesic and only 13% received a nonanalgesic adjuvant. The patterns of analgesic use in these communities corresponded well with accepted principles of cancer pain management: liberal use of opioids, use of oral morphine as the predominant agent, and avoidance of meperidine and opioid agonist/ antagonists.

Clinical research data warehouse governance for distributed research networks in the USA: a systematic review of the literature

OBJECTIVE To review the published, peer-reviewed literature on clinical research data warehouse governance in distributed research networks (DRNs). MATERIALS AND METHODS Medline, PubMed, EMBASE, CINAHL, and INSPEC were searched for relevant documents published through July 31, 2013 using a systematic approach. Only documents relating to DRNs in the USA were included. Documents were analyzed using a classification framework consisting of 10 facets to identify themes. RESULTS 6641 documents were retrieved. After screening for duplicates and relevance, 38 were included in the final review. A peer-reviewed literature on data warehouse governance is emerging, but is still sparse. Peer-reviewed publications on UK research network governance were more prevalent, although not reviewed for this analysis. All 10 classification facets were used, with some documents falling into two or more classifications. No document addressed costs associated with governance. DISCUSSION Even though DRNs are emerging as vehicles for research and public health surveillance, understanding of DRN data governance policies and procedures is limited. This is expected to change as more DRN projects disseminate their governance approaches as publicly available toolkits and peer-reviewed publications. CONCLUSIONS While peer-reviewed, US-based DRN data warehouse governance publications have increased, DRN developers and administrators are encouraged to publish information about these programs.
