Worst experiences of pain and conceptions of worst pain imaginable among nursing students

How and Why Patient Concerns Influence Pain Reporting: A Qualitative Analysis of Personal Accounts and Perceptions of Others' Use of Numerical Pain Scales

Complex factors influence how people report and interpret numerical pain ratings. Such variability can introduce noise and systematic bias into clinical pain assessment. Identification of factors that influence self-rated pain and its interpretation by others may bolster utility of these scales. In this qualitative study, 338 participants described motivations for modulating their own pain reports relative to a numerical pain scale (0–10), as well as perceptions of others’ pain reporting modulation. Responses indicated that people over-report pain to enhance provider belief/responsiveness or the likelihood of pain relief, and out of fear of future pain or potential illness. Concerns of how one’s pain affects and is perceived by others, and financial concerns motivated pain under-reporting. Unprompted, many participants reported never modulating their pain ratings, citing trust in providers and personal ethics. Similar reasons were assumed to motivate others’ pain ratings. However, participants often attributed others’ over-reporting to internal causes, and their own to external. This bias may underlie common assumptions that patients over-report pain for nefarious reasons, distort interpretation of pain reports, and contribute to pain invalidation. Recognition of patient concerns and one’s own personal biases toward others’ pain reporting may improve patient-provider trust and support precision of numerical pain ratings.

Determining Pain Detection and Tolerance Thresholds Using an Integrated, Multi-Modal Pain Task Battery

Human pain models are useful in the assessing the analgesic effect of drugs, providing information about a drug's pharmacology and identify potentially suitable therapeutic populations. The need to use a comprehensive battery of pain models is highlighted by studies whereby only a single pain model, thought to relate to the clinical situation, demonstrates lack of efficacy. No single experimental model can mimic the complex nature of clinical pain. The integrated, multi-modal pain task battery presented here encompasses the electrical stimulation task, pressure stimulation task, cold pressor task, the UVB inflammatory model which includes a thermal task and a paradigm for inhibitory conditioned pain modulation. These human pain models have been tested for predicative validity and reliability both in their own right and in combination, and can be used repeatedly, quickly, in short succession, with minimum burden for the subject and with a modest quantity of equipment. This allows a drug to be fully characterized and profiled for analgesic effect which is especially useful for drugs with a novel or untested mechanism of action.

Healthcare professionals' descriptions of care experiences and actions when assessing postoperative pain - a critical incident technique analysis

BACKGROUND

Pain is a common postoperative symptom, and length of hospital stay after surgery is short which highlights the importance of pain assessments. Experiences of assessing pain are mainly described from the perspective of nurses. In postoperative care, enrolled nurses and physicians also assess pain. It is therefore important to take note of their experiences to improve postoperative pain assessments.

OBJECTIVES

The aim of this study was, through considering critical incidents, to describe care experiences and actions taken by healthcare professionals when assessing postoperative pain.

METHODS

An explorative design employing critical incidents technique analysis was used. A total of 24 strategically selected enrolled nurses, nurses and physicians employed at orthopaedic or general surgery wards in four Swedish hospitals were interviewed. The intention was to reach variation in age, sex, profession and professional experience.

FINDINGS

In pain assessments, patient-related facilitators were patients' verbal and emotional expressions including pain ratings, while lack of consistency with observed behaviours was a barrier. Clinical competence, continuity in care and time were healthcare-related facilitators. The actions healthcare professionals took were gathering facts about patients' pain manifestations and adapting to patients' communication abilities. Patient observations, either passive or active were used to confirm or detect pain. Collaboration between healthcare professionals, including consultations with pain experts, social workers and relatives, strengthened understanding of pain.

CONCLUSIONS

Communication skills and working conditions have an impact on performance of pain assessment. Patient comfort without compromising safety is reached by including healthcare professionals' dissimilar responsibilities when collecting patients' and relatives' perspectives on current pain.

Nursing students' assessment of pain and decision of triage for different ethnic groups: An experimental study

BACKGROUND

Pain management is a priority in nursing care but little is known about the factors that affect nursing students' assessment of pain expressed by patients of different ethnic backgrounds.

OBJECTIVES

This study examined undergraduate nursing students' assessment of pain and decision of triage when pain was expressed in different languages and their relation to students' empathy and social identity. Comparison between students with and without clinical experience was also carried out.

DESIGN

This is a cross-sectional quantitative design.

SETTING

This study took place at a university in Hong Kong.

PARTICIPANTS

74 female undergraduate nursing students.

METHODS

Students listened to eight audio recordings in which an individual expressed pain in one of the two dialects of Chinese, either Cantonese or Putonghua. For each dialect, two recordings depicted mild pain and two depicted severe pain. After listening to each recording, students rated the pain level and indicated their decision of triage. Subsequently, students completed a questionnaire that measured their empathy and social identity and reported their demographics. The data were analyzed by descriptive statistics, correlational analyses, and t-tests.

RESULTS

Severe pain described in Putonghua was rated as more intense than that described in Cantonese but it was not classified as more urgent. Students with clinical experience tended to perceive mild pain as less painful and less urgent than those without clinical experience. For mild pain described in Cantonese, students with clinical experience evaluated it as more urgent than those without such experience. The empathy level of students with and without clinical experience was comparable. Students with more empathy, especially those without clinical experience, reported heightened perceived intensity of severe pain described in Putonghua.

CONCLUSIONS

Nurse educators should note that empathy, social identity, and clinical experience may alter students' pain assessment of patients from different ethnicities. Pain education needs to be reinforced.

Midwifery students' conceptions of worst imaginable pain

BACKGROUND

The Visual Analogue Scale (VAS) is one of the most widely used pain assessment scales in clinical practice and research. However, the VAS is used less frequently in midwifery than in other clinical contexts. The issue of how people interpret the meaning of the VAS endpoints (i.e. no pain and worst imaginable pain) has been discussed. The aim of this study was to explore midwifery students' conceptions of 'worst imaginable pain'.

METHODS

A sample of 230 midwifery students at seven universities in Sweden responded to an open-ended question: 'What is the worst imaginable pain for you?' This open-ended question is a part of a larger study. Their responses underwent manifest content analysis.

RESULTS

Analysis of the midwifery students' responses to the open-ended question revealed five categories with 24 sub-categories. The categories were Overwhelming pain, Condition-related pain, Accidents, Inflicted pain and Psychological suffering.

CONCLUSIONS

The midwifery students' conceptions of 'worst imaginable pain' are complex, elusive and diverse.

Registered nurses' personal responses to postoperative pain: a descriptive qualitative study

This paper explores if nurses' personal responses to postoperative pain contribute to its continuing poor management. A descriptive qualitative design used a purposive sample of 16 registered nurses (RNs), from inpatient surgical areas in the United Kingdom, to participate in one semistructured interview. These were recorded and transcribed verbatim. Analysis used Morse and Field's four stages. A complex picture of collective and individual responses emerged; uncritical adoption of the medical model, with pain as normal and focus on technical aspects of management conforming to a "reference typology." However, individual RNs were also influenced by other personal factors, and findings indicate that scrutinizing individual competency is essential to improve individual and collective practice.

The impact of experience on undergraduate preregistration student nurses' responses to patients in pain: a 2-year qualitative longitudinal study

The management of pain is consistently reported as a problematic area of practice, with limited evidence of improvements in the past 30 years. This study explores the impact of experience on student nurses' responses to patients in pain. Sixteen volunteers from a cohort of undergraduate student nurses in the U.K. participated in a qualitative longitudinal study that used two semistructured interviews 18 months apart. Interview transcripts were analyzed with the use of thematic content analysis for each individual interview stage and then additionally to identify relationships between each stage. Participants revealed an initial lack of interest in nearly all aspects of pain. At the second stage of interviews, some participants expressed increasing discernment and empathy toward patients in pain, although some continued to have minimal interest. Findings suggest that an active interest in pain is essential so that individuals can react critically to assumptions of the clinical culture they are exposed to. Further research is needed to identify how an active interest can by developed among those students for whom experience has little positive impact. Without active interest, apathy, aversion to change, and continued poor pain management practices are likely to continue.

Reliability and validity of the Acceptance Symptom Assessment Scale in assessing labour pain

OBJECTIVE

to investigate the reliability and validity of the Acceptance Symptom Assessment Scale (ASAS) in assessing labour pain.

DESIGN

a test-retest approach was used to assess reliability and validity.

SETTING

labour ward with approximately 2,400 deliveries annually in western part of Sweden.

PARTICIPANTS

forty-seven pregnant women in the latent or active phase of labour.

METHODS

a total of five pain assessments with both the ASAS and the VAS were conducted in three sessions.

MAIN OUTCOME MEASURES

correlation between ASAS and VAS.

FINDINGS

both scales demonstrated high and significant test-retest correlations (r=0.83-0.92; p<0.001). High and significant alternative-form reliability correlations (r=0.76-0.93, p<0.001) were found between ASAS and VAS ratings at all five assessments. Construct validity was established when both the ASAS and the VAS identified a pain reduction (p<0.001) 2 hrs after birth, compared to the previous assessment. Over two-thirds of the women preferred the ASAS to the VAS, mainly (n=30) because the ASAS provided more choices relating to the pain experience, making it possible to label pain acceptable/unacceptable.

CONCLUSIONS

the ASAS is interchangeable with the VAS for assessing labour pain. Over two-thirds of the women preferred it to the VAS.

What does the answer mean? A qualitative study of how palliative cancer patients interpret and respond to the Edmonton Symptom Assessment System

The Edmonton Symptom Assessment System (ESAS) is a well-known self-reporting tool for symptom assessment in palliative care. Research has shown that patients experience difficulties in the scoring and interpretation, which may lead to suboptimal treatment. The aims were to examine how palliative care cancer patients interpreted and responded to the ESAS. Eleven patients (3 F/8 M), median age 65 (34-95) with mixed diagnoses were interviewed by means of cognitive interviewing, immediately after having completed the ESAS. The highest mean scores were found with tiredness (6.3) and oral dryness (5.7). The results showed that sources of error were related to interpretation of symptoms and differences in the understanding and use of the response format. The depression and anxiety symptoms were perceived as difficult to interpret, while the appetite item was particularly prone to misunderstandings. Contextual factors, such as mood and time of the day, influenced the answers. Lack of information and feedback from staff influenced the scores. Some patients stated that they scored at random because they did not understand why and how the ESAS was used. The patients' interpretation must be considered in order to minimize errors. The ESAS should always be reviewed with the patients after completion to improve symptom management, thereby strengthening the usability of the ESAS.

Comparison of the PainMatcher and the Visual Analogue Scale for assessment of labour pain following administered pain relief treatment

OBJECTIVE

during childbirth, it is necessary to assess and monitor experienced pain and to evaluate the effect of pain relief treatment. The aim of this study was to compare the PainMatcher (PM) with the Visual Analogue Scale (VAS) for the assessment of labour pain and the effect of pain relief treatment.

DESIGN

randomised controlled trial.

SETTING

labour ward with approximately 2500 childbirths per year in western Sweden.

PARTICIPANTS

57 women with labour pain treated with acupuncture or sterile water injections scored their electrical pain threshold and pain intensity with the PM. Pain intensity was also assessed with the VAS. Electrical pain threshold and pain intensity were assessed immediately after a uterine contraction before and 30, 60, 90, 120, 150 and 180 minutes after treatment.

MEASUREMENTS AND FINDINGS

the results showed a weak correlation (r=0.13, p<0.05) between the pain intensity scores on the PM and the VAS. The PM detected changes (decrease) in pain intensity to a lower degree than the VAS. Surprisingly, in over 10% of sessions, women scored their pain intensity during a uterine contraction lower than their electrical pain threshold with the PM. However, electrical pain thresholds with the PM correlated well throughout all measurements.

CONCLUSIONS

the PM is a reliable tool for the assessment of electrical pain threshold; however, the VAS is more sensitive than the PM for recording changes in pain intensity when assessing the effects of treatment on labour pain.

IMPLICATIONS FOR PRACTICE

the PM and the VAS are not interchangeable in the case of labour pain, and there is still a need for research in this area to find a more suitable assessment instrument for the evaluation of labour pain.
