Vascularity and pain in the patellar tendon of adult jumping athletes : a 5 month longitudinal study

Background: This study investigated changes in tendon vascularity in 102 (67 men and 35 women) volleyball players over a 6 month competitive season.

Methods: Athletes were examined with both grey scale ultrasound and standardised colour Doppler settings. Vessel length and pain were measured each month on five separate occasions. Vascular tendons were divided into (i) those that were vascular on all occasions (persistent vascularity) and (ii) those that were vascular on more than two but less than five occasions (intermittent vascularity).

Results: A total of 41 of the 133 abnormal tendons were vascular on two or more occasions. Of these, 16 had persistent vascularity and 25 had intermittent vascularity. There was no significant difference in the prevalence of vascularity between men and women. None of the tendons had a pattern of vascularity over the season that could be clearly interpreted as the onset or resolution of vascularity. Subjects with changes in both tendons were more likely to have persistent vascularity (p = 0.045). Vessels were longer in tendons with persistent vascularity (p<0.000) and pain was significantly greater (p = 0.043) than in tendons with intermittent vascularity. Tendons with intermittent vascularity had similar pain scores on all days, whether or not they had detectable blood flow.

Observation of pain assessment and management- the complexities of clinical practice

• Pain assessment and management are complex issues that embrace physiological, emotional, cognitive, and social dimensions.

• This observational study sought to investigate nurse–patient interactions associated with pain assessment and management in hospitalized postsurgical patients in clinical practice settings.

• Twelve field observations were carried out on Registered Nurses' activities relating to pain with their assigned patients. All nurses were involved in direct patient care in one surgical unit of a metropolitan teaching hospital in Melbourne, Australia. Six observation times were identified as key periods for activities relating to pain, which included change of shift and high activity periods. Each observation period lasted 2 hours and was examined on two occasions.

• Four major themes were identified as barriers to effective pain management: nurses' responses to interruptions of activities relating to pain, nurses' attentiveness to patient cues of pain, nurses' varying interpretations of pain, and nurses' attempts to address competing demands of nurses, doctors and patients.

• These findings provide some understanding of the complexities impacting on nurses' assessment and management of postoperative pain. Further research using this observational methodology is indicated to examine these influences in more depth. This knowledge may form the basis for developing and evaluating strategic intervention programmes that analyse nurses' management of postoperative pain and, in particular, their administration of opioid analgesics.

Patients' decision-making strategies for managing postoperative pain

Despite technological advances, many postoperative patients continue to suffer unrelieved pain. The aim of this study was to identify the strategies used by postoperative patients to bring about pain management decisions. A single-group noncomparative study design was chosen using observations as the means of examining pain activities in 2 surgical units of a metropolitan teaching hospital in Melbourne, Australia. A total of 52 nurses and 312 patients participated in the study, and 316 pain activities were observed. The most common strategy used was patients acting as a passive recipient for pain relief (60%), whereas problem solving (23%) and active negotiation (17%) were less commonly used. Patients in this study were admitted for surgical treatment of a particular condition, and their subsequent pain was specifically related to this acute event. Therefore, the lack of familiarity of the situation and the severity of pain experienced may have encouraged passivity. Patients may have also felt uncertain about how to approach the pain decision, preferring to defer to nurses. Because increased pain levels can be associated with fear, patients could have been unwilling to speak with nurses to discuss their need for pain relief.

Nurses' reassessment of postoperative pain after analgesic administration

Objectives: To identify when and how nurses reassess patients' pain after analgesic administration in the postoperative context.
Methods: Fifty-two nurses were observed caring for postoperative patients (N = 364) in 2 surgical settings in a major metropolitan hospital. Seventy-four observation periods of 2 hours duration were studied. The research assistant observed nurses' activities in caring for the allocated patients'. detailing behavioral and verbal responses onto audiotape.
Results: Of the 316 pain activities Ihat occurred in 74 observation periods. 14 (4.4%) were reassessments after analgesic administration. Four themes were evident from the 14 reassessments: opportunistic reassessment. the use of simple questioning, a focus on surgical wound pain not procedural
pain, and nurse-initiated reassessment.
Conclusions: Despite the focus on meeting standards of care in the area of pain management, there was an extraordinary lack of patient reassessment by nurses after the administration of analgesics. Given Ihe raised awareness internationally on assessment generally and a lack of evidence focused on reassessment after an intervention, this may explain why research is failing to identify shifts in pain severity scores and indeed patient pain.

Acute pain management: Implications of scientific evidence for nursing practice in the postoperative context

Unrelieved acute pain remains prevalent in hospitalized patients despite advances in pain management. A decade after the Australian National Health and Medical Research Council called for improved pain management practices by health professionals, it released clinical guidelines to provide clinicians with current scientific evidence to augment their clinical decision-making. This paper examines the implications of national guidelines on nursing practice and highlights the inadequacies of current implementation policies. Pain management guidelines have failed to decrease patients' postoperative pain because organizations and researchers have ignored the impact of contextual influences on clinicians' decision-making. It is recommended that for successful implementation of national guidelines to occur at the local level of practice, organizations must assist clinicians to identify local influences on their decision-making, to address the issues specific to their own work environment and to evaluate any changes in practice.

2001 Volvo Award winner in clinical studies : effects of a media campaign on back pain beliefs and its potential influence on management of low back pain in general practice

Study Design. Quasi-experimental, nonrandomized, nonequivalent, parallel group-controlled study involving before and after telephone surveys of the general population and postal surveys of general practitioners was conducted, with an adjacent state used as a control group.


Objectives. To evaluate the effectiveness of a population-based intervention designed to alter beliefs about back pain, influence medical management, and reduce disability and workers’ compensation–related costs.


Summary of Background Data. A multimedia campaign begun during 1997 in Victoria, Australia, positively advised patients with back pain to stay active and exercise, not to rest for prolonged periods, and to remain at work.


Methods. The campaign’s impact on population beliefs about back pain and fear-avoidance beliefs was measured in telephone surveys, and the effect of the campaign on the potential management of low back pain by general practitioners was assessed by eliciting their likely approach to two hypothetical scenarios in mailed surveys. Demographically identical population groups in Victoria and the control state, New South Wales, were surveyed at three times: before, during, and after intervention in Victoria.


Results. The studies were completed by 4730 individuals in the general population and 2556 general practitioners. There were large statistically significant improvements in back pain beliefs over time in Victoria (mean scores on the Back Beliefs Questionnaire, 26.5, 28.4, and 29.7), but not in New South Wales (26.3, 26.2, and 26.3, respectively). Among those who reported back pain during the previous year, fear-avoidance beliefs about physical activity improved significantly in Victoria (mean scores on the Fear-Avoidance Beliefs Questionnaire for physical activity, 14, 12.5, and 11.6), but not in New South Wales (13.3, 13.6, and 12.7, respectively). General practitioners in Victoria reported significant improvements over time in beliefs about back pain management, as compared with their interstate colleagues. There were statistically significant interactions between state and time for 7 of 10 responses on management of acute low back pain, and for 6 of 10 responses on management of subacute low back pain.


Conclusion. A population-based strategy of providing positive messages about back pain improves the beliefs of the general population and general practitioners about back pain and appears to influence medical management.

Malingering pain in the medicolegal context

Malingering—the willful, deliberate, and fraudulent feigning or exaggeration of illness—was originally described as a means of avoiding military service. In present-day clinical practice, malingering may occur in circumstances where the person wishes to avoid legal responsibility or in situations where compensation or some other benefit might be obtained. In law, the term malingering is used in relation to persons to whom military regulations apply; in other situations, malingering is regarded as fraud and may lead to charges of perjury or criminal fraud. Assertions that an individual is malingering are particularly common in clinical settings where the complaint is of a subjective nature and is not accompanied by objectively demonstrable organic abnormalities. This may occur in relation to complaints of pain in situations where the person is entitled to receive pain-contingent compensation or is suing for damages. In this article, we will review the literature on pain and malingering and discuss attempts that have been made to develop methods and guidelines for the detection of malingered pain. There are, however, no valid clinical methods of assessment of possible malingering of pain. In our view, the ultimate issue of the veracity of the plaintiff is for the Court to decide, and epithets such as “malingerer” have no place in reports prepared for legal purposes by health care professionals.

Assessment of patient pain in the postoperative context

Because of its subjective nature, the assessment of pain requires the use of comprehensive practices that accurately reflect a patient’s experiences of pain. The purpose of this study was to determine how nurses make decisions in their assessment of patients’ pain in the postoperative clinical setting. An observational design was chosen as the means of examining pain activities in two surgical units of a metropolitan teaching hospital in Melbourne, Australia. Six fixed observation times were selected. Each 2-hour observation period was examined 12 times thus resulting in 74 observations. In total, 316 pain activities were determined. Five themes relating to assessment were identified from the data analysis: simple questioning, use of a pain scale, complex assessment, the lack of pain assessment, and physical examination for pain. The study identified how nurses’ prioritization of work demands created barriers in conducting timely and comprehensive pain assessment decisions.

Blood-nourishing and hard-softening capsule costs less in the management of osteoarthriticknee pain : A randomized controlled trial

The blood-nourishing and hard-softening (BNHS) capsule is a traditional Chinese formula used in the symptomatic treatment of inflammation and pain. We conducted this randomized controlled trial to compare the efficacy of BNHS with other commonly prescribed drugs. We recruited 120 patients from two teaching hospitals; 30 patients in each hospital were randomly assigned to receive BNHS. In one hospital, the 30 controls were given another traditional Chinese drug; whereas a Western medicine (chondroprotection drug/Viartril-s) was used as the control in the other hospital. Intervention was carried out over a period of 4 weeks. Primary outcome measures included self-reported pain level, and changes in stiffness and functional ability as measured by the Western Ontario McMaster Universities Osteoarthritis (WOMAC) index. Mixed models were used for statistical analysis. Substantial improvements in disease-specific symptoms were observed, after 4 weeks of treatment, in patients taking BNHS capsules. As assessed by the WOMAC index, pain level of the BNHS group decreased by 57% [95% confidence interval (CI) = 50, 63], stiffness by 63% (95% CI = 55, 71) and functional ability increased by 56% (95% CI = 50, 63). No significant differences were found in any of the outcome measures between the BNHS group and either of the comparison groups. No severe adverse effects were reported. However, this study lacked a placebo group; therefore, we conclude that BNHS appears to be as effective as commonly prescribed medicines for the relief of pain and dysfunction in knee osteoarthritis patients, but costs a lot less than other Western and herbal drugs in the study.

Ice and pulsed electromagnetic field to reduce pain and swelling after distal radius fractures

Objective: To examine the relative effectiveness of ice therapy and/or pulsed electromagnetic field in reducing pain and swelling after the immobilization period following a distal radius fracture.Methods: A total of 83 subjects were randomly allocated to receive 30 minutes of either ice plus pulsed electromagnetic field (group A); ice plus sham pulsed electromagnetic field (group B); pulsed electromagnetic field alone (group C), or sham pulsed electromagnetic field treatment for 5 consecutive days (group D). All subjects received a standard home exercise programme. A visual analogue scale was used for recording pain; volumetric displacement for measuring the swelling of the forearm; and a hand-held goniometer for measuring the range of wrist motions before treatment on days 1, 3 and 5.Results: At day 5, a significantly greater cumulative reduction in the visual analogue scores as well as ulnar deviation range of motion was found in group A than the other 3 groups. For volumetric measurement and pronation, participants in group A performed better than subjects in group D but not those in group B.Conclusion: The addition of pulsed electromagnetic field to ice therapy produces better overall treatment outcomes than ice alone, or pulsed electromagnetic field alone in pain reduction and range of joint motion in ulnar deviation and flexion for a distal radius fracture after an immobilization period of 6 weeks.

Nurses' strategies for managing pain in the postoperative setting

Acute pain is a significant problem in the postoperative setting. Patients report a lack of information about pain-control measures and ineffective pain control. Nurses continue to rely on pharmacologic measures and tend to under-administer analgesics. The purpose of this study was to determine the strategies nurses used to manage patients’ pain in the postoperative setting. It also sought to examine the effect of context, including organization of care, nurses’ prioritization of work activities, and pressures during a working shift, on their pain-management strategies. An observational design was used in two surgical units of a metropolitan teaching hospital in Melbourne, Australia. Six fixed observation times were identified as key periods for pain activities, each comprising a 2-hour duration. An observation period was examined at least 12 times, resulting in the completion of 74 observations and the identification of 316 pain cases. Fifty-two nurses were observed during their normal day’s work with postoperative patients. Six themes were identified: managing pain effectively; prioritizing pain experiences for pain management; missing pain cues for pain management; regulators and enforcers of pain management; preventing pain; and reactive management of pain. The findings highlighted the critical nature of communication between clinicians and patients and among clinicians. It also demonstrated the influence of time on management strategies and the relative importance that nurses place on nonpharmacologic measures in actual practice. This research, which portrays what happens in actual clinical practice, has facilitated the identification of new data that were not evident from other research studies.
