Qualitative research contribution to a randomized clinical trial.

Qualitative research may be combined fruitfully with intervention studies, but few examples provide detailed methodological strategies for doing so. In this article, we describe the qualitative component of a randomized clinical trial (RCT) of the PRO-SELF(c) Pain Control Program, an intervention that provides individualized education, coaching, and support for cancer pain management. We conducted three qualitative analyses of verbatim transcripts of "real-time" audiotaped intervention sessions. As a result, we were better able to ascertain the nature of the individualized coaching component of the intervention, patient and family caregiver use of selected intervention tools, and reasons the intervention did not work for some patients. Study results were used to increase the specificity with which the coaching portion of the intervention is described in the intervention protocol.

Patient-controlled modalities for acute postoperative pain management.

Although numerous clinical practice guidelines for pain management have been published throughout the last 12 years, inadequate pain relief remains a significant health care issue. Several patient-controlled analgesia (PCA) modalities are currently available for the treatment of acute postoperative pain, including intravenous (IV) PCA, epidural (PCEA), and oral PCA. Although PCEA and IV PCA are both commonly used modalities, IV PCA is considered the standard of care for postoperative pain management. Limitations of this modality do exist, however. Consequently, noninvasive PCA systems are under development to circumvent many of these limitations, including the fentanyl hydrochloride patient-controlled transdermal system (PCTS); (IONSYS Ortho-McNeil Pharmaceutical, Raritan, NJ) and a number of patient-controlled intranasal analgesia (PCINA) delivery systems. The objective of this article is to review the PCA modalities currently in use and to discuss those in development for the treatment of acute postoperative pain.

Are there phases to the vaso-occlusive painful episode in sickle cell disease?

The purpose of this study was to describe the pain experience of children with sickle cell disease who were hospitalized for vaso-occlusive painful episodes. The pain experience, and signs and symptoms prior to admission and during hospitalization, are presented in the context of whether there is evidence to support the existence of phases to a vaso-occlusive painful episode. Children were interviewed about the onset of the painful episode and were asked to describe their pain from the day of admission to the day of discharge from the hospital. They were also observed for the absence or presence of signs and symptoms associated with the painful vaso-occlusive episode. Findings from this study provide some evidence to support previous observations related to changes during the evolution of painful episodes that may be occurring in phases (e.g., evolving, inflammatory, resolving), as previously described in adults and children. These phases had different names, although the concepts were similar.

Predictors of quality of life in oncology outpatients with pain from bone metastasis.

The relationship between pain and quality of life (QOL) in cancer patients is complex due to the number and the diversity of factors that can influence pain and QOL. The aims of this study of oncology outpatients with pain from bone metastasis were: 1) to determine the extent to which pain characteristics (i.e., severity, duration, meaning of pain, and perceived availability and efficacy of pain relief), psychological distress (i.e., depression), physical functioning, social functioning and QOL are intercorrelated, and 2) to determine which of these variables are important predictors of QOL. A total of 157 oncology outpatients completed questionnaires that evaluated pain, QOL, depression, physical functioning, and social functioning at the time of enrollment into a randomized clinical trial that evaluated the effectiveness of a psychoeducational intervention to improve cancer pain management. Pearson product moment correlation coefficients were calculated to examine the relationships among the study variables. A blockwise, hierarchical multiple regression analysis was performed to determine which variables were the most important predictors of QOL. Meaning of pain was significantly correlated with all the other variables, in particular pain intensity and duration. The most important factors that predicted QOL were depression, social functioning, and physical functioning. Depression proved to be the most important predictor of QOL.

Categorizing the severity of cancer pain: further exploration of the establishment of cutpoints.

Previous work by Serlin and colleagues [Serlin R C, Mendoza T R, Nakamura Y, Edwards K R, Cleeland C S. When is cancer pain mild, moderate, or severe? Grading pain severity by its interference with function. Pain 1995;61:277-84] established cutpoints for mild, moderate, and severe cancer pain based on the pain's level of interference with function. Recent work [Jensen M P, Smith D G, Ehde D M, Robinson L R. Pain site and the effects of amputation pain: further clarification of the meaning of mild, moderate, and severe pain. Pain 2001;91:317-22; Zelman D C, Hoffman D L, Seifeldin R, Dukes, E. Development of a metric for a day of manageable pain control: derivation of pain severity cutpoints for low back pain and osteoarthritis. Pain 2003;106(1/2):35-42]found differences in cutpoints for pain severity for different pain-related conditions. Reasons for these discrepancies may relate to the methods used to determine the cutpoints or to differences based on the type or the cause of the pain. The purposes of this study were to determine the optimal cutpoints for mild, moderate, and severe pain based on patients' ratings of average and worst pain severity, using a larger range of potential cutpoints, and to determine if those cutpoints distinguished among the three pain severity groups on several outcome measures. Results from a homogenous sample of oncology outpatients with pain from bone metastasis confirm a non-linear relationship between cancer pain severity and interference with function and also confirm that the boundary between a mild and a moderate level of cancer pain is at 4 on a 0-10 numeric rating scale. However, this analysis did not confirm the boundary between moderate and severe cancer pain previously described by Serlin and colleagues [Serlin R C, Mendoza T R, Nakamura Y, Edwards K R, Cleeland C S. When is cancer pain mild, moderate, or severe? Grading pain severity by its interference with function. Pain 1995;61:277-84]. In addition, these results were not consistent with the cutpoints that were found for back pain, phantom limb pain, pain 'in general', or osteoarthritis pain reported by Jensen and colleagues and Zelman and colleagues [Jensen M P, Smith D G, Ehde D M, Robinson L R. Pain site and the effects of amputation pain: further clarification of the meaning of mild, moderate, and severe pain. Pain 2001;91:317-22; Zelman D C, Hoffman D L, Seifeldin R, Dukes, E. Development of a metric for a day of manageable pain control: derivation of pain severity cutpoints for low back pain and osteoarthritis. Pain 2003;106(1/2):35-42]. Possible explanations for these differences are discussed, as well as implications for future research.

Time-contingent dosing of an opioid analgesic after tonsillectomy does not increase moderate-to-severe side effects in children.

As part of a randomized clinical trial that compared three different analgesic dosing regimens ( Sutters et al., 2004 ), the purpose of this study, in children who underwent tonsillectomy, was to determine whether around-the-clock (ATC) dosing of acetaminophen with codeine, compared with as-needed (PRN) dosing, increased the frequency of moderate-to-severe opioid-related side effects (i.e., daytime sedation, lightheadedness, nightmares, nausea, vomiting, and constipation) in the first 3 days after surgery. Because no differences were found in pain intensity scores and in the amount of analgesic administered between the two ATC groups (i.e., with and without coaching), for these analyses, the two groups were combined ( n = 52) and compared with the PRN group ( n = 28). Each side effect was recoded into a dichotomous response (i.e., 0 = did not have symptoms or had slight symptoms; 1 = symptoms that were moderate, severe, or very severe) to provide an adequate sample size in each cell for the statistical analyses. No differences were found in the frequency of moderate-to-severe side effects between the ATC and PRN groups at any of the postoperative assessments. The number of children who reported moderate-to-severe daytime sedation decreased over time in both the PRN ( p = .02) and ATC groups ( p = .01). Children in the ATC groups reported a statistically significant decrease over time in vomiting ( p = .001) and feeling lightheaded or dizzy ( p = .003), and a significant increase in constipation ( p = .018). Except for daytime sedation, changes, over time, in the frequency of moderate-to-severe side effects were not observed in the PRN group.

The use of 'as-needed' range orders for opioid analgesics in the management of acute pain: a consensus statement of the American Society for Pain Management Nursing and the American Pain Society.

The use of "as-needed" or "PRN" range orders for opioid analgesics in the management of acute pain is a common clinical practice. This approach provides flexibility in dosing to meet individual patients' unique analgesic requirements. Range orders enable necessary and safe dose adjustments based on an individual's response to treatment. This paper presents the consensus statement of the American Society for Pain Management Nursing and the American Pain Society on the use of "as-needed" range orders for opioid analgesics in the management of acute pain.

The PRO-SELF pain control program improves patients' knowledge of cancer pain management.

PURPOSE/OBJECTIVES: To evaluate the effectiveness of a psychoeducational program (i.e., PRO-SELF Pain Control Program) compared to standard care in increasing patients' knowledge regarding cancer pain management. DESIGN: Randomized clinical trial. SETTING: Seven outpatient settings in northern California. SAMPLE: 174 outpatients with cancer and pain from bone metastasis. METHODS: Following randomization into either the PRO-SELF or standard care group, patients completed the Pain Experience Scale (PES) prior to and at the completion of the intervention. MAIN RESEARCH VARIABLES: Total and individual item scores on the PES. FINDINGS: Total PES knowledge scores increased significantly in the PRO-SELF group (21%) compared to the standard care group (0.5%). Significant improvements in knowledge scores for patients in the PRO-SELF group were found on five of the nine PES items when compared to baseline scores. CONCLUSIONS: The PRO-SELF Pain Control Program was an effective approach to increase patients' knowledge of cancer pain management. IMPLICATIONS FOR NURSING: The use of a structured paper-and-pencil questionnaire, such as the PES, as part of a psychoeducational intervention provides an effective foundation for patient education in cancer pain management. Oncology nurses can use patients' responses to this type of questionnaire to individualize the teaching and to spend more time on the identified knowledge deficits. This individualized approach to education about pain management may save staff time and improve patient outcomes.

Recent advances in understanding pain mechanisms provide future directions for pain management.

PURPOSE/OBJECTIVES: To review current knowledge of neurobiologic mechanisms that generate and maintain chronic pain and to explain how they might be applied in targeting treatment of chronic, inflammatory, and neuropathic pain syndromes. DATA SOURCES: Published research, literature review articles, and abstracts as well as national statistics. DATA SYNTHESIS: Treatment for chronic pain associated with cancer and other syndromes remains suboptimal and falls significantly short of clinical needs. Data highlight the role that multiple neurobiologic mechanisms play in modulating and maintaining pain at various levels of the central and peripheral nervous systems. Novel agents have been developed that use a more targeted approach to treating chronic pain. CONCLUSIONS: A growing body of evidence highlights the critical role that neurobiologic mechanisms play in the initiation and maintenance of chronic pain. A thorough understanding of these mechanisms ultimately may result in targeted treatment approaches that focus on the central and peripheral mechanisms involved in mediation of chronic, inflammatory, and neuropathic pain syndromes. IMPLICATIONS FOR NURSING: A majority of patients undergoing active treatment for cancer experiences unrelieved pain. By gaining a better understanding of the mechanisms that generate and maintain chronic pain, oncology nurses can promote targeted pain management strategies that incorporate novel therapeutic agents.

Randomized clinical trial of the effectiveness of a self-care intervention to improve cancer pain management.

PURPOSE: This randomized clinical trial tested the effectiveness of the PRO-SELF Pain Control Program compared with standard care in decreasing pain intensity scores, increasing appropriate analgesic prescriptions, and increasing analgesic intake in oncology outpatients with pain from bone metastasis. PATIENTS AND METHODS: Patients were randomly assigned to the PRO-SELF intervention (n = 93) or standard care (n = 81). Patients in the standard care arm were seen by a research nurse three times and were called three times by phone between the home visits. PRO-SELF group patients were seen by specially trained intervention nurses and received a psychoeducational intervention, were taught how to use a pillbox, and were given written instructions on how to communicate with their physician about unrelieved pain and the need for changes in their analgesic prescriptions. Patients were coached during two follow-up home visits and three phone calls on how to improve their cancer pain management. RESULTS: Pain intensity scores decreased significantly from baseline (all P <.0001) in the PRO-SELF group (ie, least pain, 28.4%; average pain, 32.5%; and worst pain, 27.0%) compared with the standard care group (ie, least increased by 14.6%, average increased by 1.9%, and worst decreased by 1.2%). The percentage of patients in the PRO-SELF group with the most appropriate type of analgesic prescription increased significantly from 28.3% to 37.0% (P =.008) compared with a change from 29.6% to 32.5% in the standard care group. CONCLUSION: The use of a psychoeducational intervention that incorporates nurse coaching within the framework of self-care can improve the management of cancer pain.

Prevalence and characteristics of chronic pain in the general Norwegian population.

BACKGROUND: Population-based studies suggest that prevalence of chronic pain is increasing. The purpose of this study was to determine the prevalence of chronic pain in a sample drawn from the general Norwegian population. In addition, the characteristics of chronic pain, as well as differences in demographic characteristics and health-related variables between persons with and without chronic pain were evaluated. METHODS: A total of 4000 Norwegian citizens, were randomly drawn from the National Register, by Statistics Norway and were mailed a questionnaire. RESULTS: The response rate was 48.5%. The majority of the sample was female (51%), married (59%), and working for pay (69%) with a mean age of 45.2 years. The prevalence of chronic pain in the total sample was 24.4%, and 65% of the participants with chronic pain indicated that they had experienced chronic pain for over 5 years. The cause of the pain was not specified by 57% of the participants in chronic pain, and 31% reported no pain treatments. Women, older individuals, persons with less education, and those who were pensioned, reported chronic pain more frequently. The results of a logistic regression analysis indicate that the variables that provide unique contributions to predicting pain group memberships were: gender, education, being frequently ill, or having a chronic illness. CONCLUSIONS: These findings suggest that chronic pain is a significant problem in the general Norwegian population, and that gender, education, being frequently ill, or having a chronic illness are important variables in predicting pain group membership.

No evidence for sex differences in the severity and treatment of cancer pain.

While chronic pain is experienced by approximately 50-90% of patients with metastatic cancer, little is known about sex differences in chronic cancer pain. Therefore, the purposes of this study, in a sample of oncology outpatients (n=187) who were experiencing pain from bone metastasis, were: 1) to determine if there were sex differences in various pain characteristics, including pain intensity, and 2) to determine if there were sex differences in the prescription and consumption of analgesic medications. No significant sex differences were found in any of the baseline pain characteristics. In addition, no significant sex differences were found in analgesic prescriptions or intake of analgesic medications. Of note, men reported significantly higher pain interference scores for sexual activity than women. The study findings are important because they suggest that, unlike in acute pain, sex may not influence patients' perceptions of and responses to chronic cancer pain.

A randomized clinical trial of the effectiveness of a scheduled oral analgesic dosing regimen for the management of postoperative pain in children following tonsillectomy.

The purpose of this study was to determine whether around-the-clock (i.e. ATC) dosing of acetaminophen with codeine, with or without nurse coaching, compared to standard care with as needed (i.e. PRN) dosing: reduced children's reports of pain intensity with and without swallowing; increased pain relief, and increased analgesic consumption. Eighty children, 6-15 years, undergoing tonsillectomy were randomized to one of three treatment groups to receive acetaminophen with codeine (120 mg/12 mg/5 ml) for 3 days after surgery: PRN group (N = 28)-every 4 h PRN, with standard postoperative instructions, without nurse coaching; ATC group (N = 26)-every 4 h ATC, with standard postoperative instructions, without nurse coaching; and ATC+coaching group (N = 26)-every 4 h ATC, with standard postoperative instructions and nurse coaching. In all three groups, significant decreases were found over time in pain intensity scores at rest (P < 0.001) and with swallowing (P < 0.001). However, mean pain scores at rest and with swallowing were >3/10 until the fourth evening after tonsillectomy. Children in both ATC dosing groups received significantly greater amounts of acetaminophen and codeine than children in the PRN group (P < 0.003). No significant differences were found in the amount of analgesic administered between the ATC dosing groups with and without nurse coaching. No significant differences were found in the amount of nausea and vomiting among the three groups. Scheduled dosing of acetaminophen with codeine did not provide adequate pain relief for children following tonsillectomy. Nurse coaching does not increase parent's adherence with an ATC dosing schedule.

Gender differences in chronic pain--findings from a population-based study of Norwegian adults.

The purpose of this study was to evaluate for gender differences in the experience of chronic pain and the impact of chronic pain on quality of life (QOL). A total of 1,912 out of 4,000 Norwegian citizens returned a mailed questionnaire, and 24.4% reported chronic pain. More women than men reported chronic pain, and women reported significantly higher pain intensity scores than men did. Although the duration of chronic pain was similar in women and men, women more often received treatment for their chronic pain. Men in chronic pain reported a poorer QOL than women did. Although specific variables that predicted present pain intensity in women and men differed, the variables that explained the largest percentage of the variance in pain for both genders were the disease and the pain location variables. These findings support previously published studies that document gender differences in chronic pain and extend the work to the impact of chronic pain on QOL.

The use of "as-needed" range orders for opioid analgesics in the management of acute pain: a consensus statement of the American Society for Pain Management Nursing and the American Pain Society.

The use of "as needed" or "PRN" range orders for opioid analgesics in the management of acute pain is a common clinical practice. This approach provides flexibility in dosing to meet individual patients' unique analgesic requirements. Range orders enable necessary and safe dose adjustments based on an individual's response to treatment. The purpose of this paper is to present the consensus statement of the American Society for Pain Management Nursing and the American Pain Society on the use of "as-needed" range orders for opioid analgesics in the management of acute pain. The implementation of this statement should promote quality pain management through safe medication practices and the appropriate use of range orders for opioid analgesics in acute pain management.

Impaired sleep and rhythms in persons with cancer.

This review includes research findings from sleep-related studies on specific types of cancers, on specific types of treatment protocols, and on persons with end-stage cancer regardless of treatment protocol. Since treatment protocols have evolved in the past decade, literature since 1990 is emphasized. We conclude that researchers should design studies that attend to prior sleep history, gender, type of cancer and treatment modalities, and the specific type of sleep problems experienced over the course of diagnosis, treatment, and recovery. More research is also needed to understand sleep problems in children with cancer and sleep problems in family caregivers. Research is also needed on effective pharmacological and non-pharmacological interventions. Daytime functioning, daytime sleepiness, and altered circadian rhythms should be considered salient outcomes in addition to severity of cancer-related fatigue. Clinicians should consider whether a patient's sleep problem has been chronic and unrelated to cancer, or precipitated by diagnosis and treatment. The specific type of sleep problem should be ascertained so that appropriate interventions can be prescribed. Appropriate interventions can include either pharmacological medication or behavioral strategies, and each has the potential to promote restorative sleep and thereby improve the patient's quality of life, daytime functioning, and well-being.
