The roles of gender and profession on gender role expectations of pain in health care professionals

Trends, Predictors, and Potential Disparities of Palliative Care Utilization Among Older Adults With Hip Fractures: A Retrospective Analysis of the National Inpatient Sample, 2016-2020

Objectives: To assess the trends in palliative care consultation utilization and identify associated factors among older adults hospitalized with hip fractures in the United States between 2016 and 2020. Methods: We conducted a retrospective cohort study using data from the National Inpatient Sample from 2016 to 2020. The study included patients aged 65 and older admitted to hospital with a primary diagnosis of hip fracture. We identified palliative care consultations using ICD-10 code Z51.5. Multivariate logistic regression analyses were performed to identify predictors of palliative care utilization, adjusting for demographics, clinical variables, and hospital characteristics. Results: A total of 293,749 admissions for hip fractures were identified, of which 9546 (3.2%) had palliative care consultations. A consistent upward trend was seen in the proportion of patients receiving palliative care consultations across all fracture types. Patients of color (Black: odds ratio [OR] = 0.73, 95% confidence interval [CI]: 0.65-0.83; Hispanic: OR = 0.67, 95% CI: 0.60-0.75 compared to White), those in lower-income quartiles (lowest: OR = 0.81, 95% CI: 0.76-0.87 compared to highest), smaller hospital size (OR = 0.84, 95% CI: 0.79-0.89 compared to large), and rural hospital (OR = 0.63, 95% Cl: 0.59-0.68, compared to urban teaching) were associated with fewer palliative care consultations. Conclusion: The number of palliative care consultations during hip fracture hospital admission was low, although the proportion increased over time. Significant disparities were observed and further research should explore barriers to palliative care access and develop strategies to enhance its delivery across diverse healthcare settings.

Sex bias consideration in healthcare machine-learning research: a systematic review in rheumatoid arthritis

OBJECTIVE

To assess the acknowledgement and mitigation of sex bias within studies using supervised machine learning (ML) for improving clinical outcomes in rheumatoid arthritis (RA).

DESIGN

A systematic review of original studies published in English between 2018 and November 2023.

DATA SOURCES

PUBMED and EMBASE databases.

STUDY SELECTION

Studies were selected based on their use of supervised ML in RA and their publication within the specified date range.

DATA EXTRACTION AND SYNTHESIS

Papers were scored on whether they reported, attempted to mitigate or successfully mitigated various types of bias: training data bias, test data bias, input variable bias, output variable bias and analysis bias. The quality of ML research in all papers was also assessed.

RESULTS

Out of 52 papers included in the review, 51 had a female skew in their study participants. However, 42 papers did not acknowledge any potential sex bias. Only three papers assessed bias in model performance by sex disaggregating their results. Potential sex bias in input variables was acknowledged in one paper, while six papers commented on sex bias in their output variables, predominantly disease activity scores. No paper attempted to mitigate any type of sex bias.

CONCLUSIONS

The findings demonstrate the need for increased promotion of inclusive and equitable ML practices in healthcare to address unchecked sex bias in ML algorithms.

Race and gender biases in assessing pain intensity and medication needs among Chinese observers

Introduction

Pain-related decision-making can be influenced by the caregiver and sufferer's demographic factors, such as race and gender, which are commonly considered individually. However, such factors may influence pain assessment interdependently based on caregivers' stereotypical beliefs.

Objectives

This study investigated how sufferers' race and gender affect Chinese observers' evaluations of pain intensity and medication needs and the associations with the observers' race and gender-related stereotypical beliefs.

Methods

One hundred sixty-two Chinese participants completed a pain facial expression rating task assessing the level of pain intensity and the extent to which they believe the sufferer needs pain medication for East Asian, White, and Black sufferers, followed by a battery of questionnaires measuring their gender and race role expectation of pain.

Results

Chinese observers were more stringent on East Asians' pain intensity and needs for medication than Whites and Blacks'. However, when Black and East Asian sufferers were perceived to have a similar level of pain, East Asians were more likely to receive medication than Blacks, which is partly due to the observers' stereotypical beliefs that Blacks would have a speedier recovery than East Asians.

Conclusions

Our results provided evidence that in addition to the in-versus-out-group preferences, one's sociocultural-related stereotypical beliefs can account for racial disparities in pain-related decision-making.

The interplay of fear of pain, emotional states, and pain perception in medical and nursing students: A cross-sectional study

BACKGROUND

Fear of pain is known to influence pain perception and worsen pain outcomes. However, its relationship with pain threshold remains unclear. Negative emotional states, namely depression, anxiety, and stress, have been found to increase fear of pain. Previous pain experiences, both undergone and observed, can also influence fear of pain. Furthermore, healthcare students' interactions with pain patients may be influenced by fear of pain and pain perception. This study aimed to assess fear of pain among Portuguese medical and nursing students, analyse its association with sex, negative emotional states, previous pain experiences, and curricular year, and evaluate the influence of fear of pain on heat pain threshold.

METHODS

A survey based on validated Portuguese questionnaires was carried out. Participants were then invited for quantitative sensory tests to assess heat pain threshold.

RESULTS

Fear of pain was similar for medical and nursing students. Female students presented a higher fear of medical pain. Stress was associated with an increased fear of severe pain. Previous painful experiences, particularly those involving medical procedures, have been found to be variably associated with fear of pain, depending on the type and characteristics of these experiences. No associations were found between fear of pain and curricular year, nor between heat pain threshold and sex or fear of pain.

CONCLUSIONS

This study highlights relevant aspects of the emotional and cognitive modulation of fear of pain and pain perception in medical and nursing students. The influence of previous pain experiences on fear of pain is also essential because healthcare students are frequently exposed to painful medical situations during their courses. As altered pain perception can influence their role as future healthcare professionals, the study of fear of pain and its modulators in healthcare students represents an important research field.

Being a woman and an orthopaedic surgeon-A primer on the challenges we face

A higher number of women are graduating from medical schools than men, yet orthopedic surgery continues to register the lowest proportion of female surgeons and residents of the surgical specialties. This trend is observed not only in North America but also globally. The presence of a more diverse workforce has been shown to lead to improved patient outcomes, enhanced efficiencies, and overall wellness within healthcare systems and would be of benefit to the orthopedic surgery profession. This primer aims to provide surgeons and leaders with evidence-based insights into diversity, equity, and equality, as well as define barriers and potential solutions pertaining to women in orthopedic surgery.

Ganoderma tsuage promotes pain sensitivity in aging mice

Advances in modern medicine have extended human life expectancy, leading to a world with a gradually aging society. Aging refers to a natural decline in the physiological functions of a species over time, such as reduced pain sensitivity and reaction speed. Healthy-level physiological pain serves as a warning signal to the body, helping to avoid noxious stimuli. Physiological pain sensitivity gradually decreases in the elderly, increasing the risk of injury. Therefore, geriatric health care receives growing attention, potentially improving the health status and life quality of the elderly, further reducing medical burden. Health food is a geriatric healthcare choice for the elderly with Ganoderma tsuage (GT), a Reishi type, as the main product in the market. GT contains polysaccharides, triterpenoids, adenosine, immunoregulatory proteins, and other components, including anticancer, blood sugar regulating, antioxidation, antibacterial, antivirus, and liver and stomach damage protective agents. However, its pain perception-related effects remain elusive. This study thus aimed at addressing whether GT could prevent pain sensitivity reduction in the elderly. We used a galactose-induced animal model for aging to evaluate whether GT could maintain pain sensitivity in aging mice undergoing formalin pain test, hot water test, and tail flexes. Our results demonstrated that GT significantly improved the sensitivity and reaction speed to pain in the hot water, hot plate, and formalin tests compared with the control. Therefore, our animal study positions GT as a promising compound for pain sensitivity maintenance during aging.

Gender-based differences in assessment and management of acute abdominal pain in the emergency department: A retrospective audit

BACKGROUND

Previous research has identified gender-based differences in acute pain management in the emergency department [ED]. The aim of this study was to compare pharmacological management of acute abdominal pain in the ED by gender.

METHODS

A retrospective chart audit was conducted at one private metropolitan ED including adult patients (18-80 years) who presented with acute abdominal pain in 2019. Exclusion criteria included: pregnancy, repeat presentation within the study period, pain-free at initial medical review or documented refusal of analgesia, and oligo-analgesia. Comparisons by gender included: (1) analgesia type and (2) time to analgesia. Bivariate analysis was undertaken using SPSS.

RESULTS

There were 192 participants: 61 (31.6 %) men and 131 (67.9 %) women. Men were more likely to get combined opioid and non-opioid medication as first line analgesia (men: 26.2 % n = 16; women: 14.5 % n = 19, p = .049). Median time from ED presentation to analgesia was 80 min for men (IQR: 60) versus 94 min for women (IQR: 58), (p = .119). Women (25.2 % n = 33) were more likely to receive their first analgesic after 90 min from ED presentation compared to men versus men (11.5 %, n = 7 p = .029). In addition, women waited longer before receiving second analgesia (women: 94, men: 30 min, p = .032).

CONCLUSION

Findings confirm there are differences in pharmacological management of acute abdominal pain in the ED. Larger studies are required to further explore differences observed in this study.

Veterinary education and experience shape beliefs about dog breeds Part 1: Pain sensitivity

Over 95% of veterinarians report believing that dog breeds differ in pain sensitivity. Ratings made by veterinarians differ from those of the general public, suggesting these beliefs may be learned during veterinary training or clinical experiences. Therefore, the current study's primary objective was to evaluate dog breed pain sensitivity ratings during veterinary training and compare these ratings to those of the general public and undergraduates in animal-health related fields. Using an online survey, members of the general public, undergraduates, veterinary students across all four years, and veterinary faculty and staff rated pain sensitivity of 10 different dog breeds, identified only by their pictures. Compared to the general public and undergraduates, veterinary students rated pain sensitivity across breeds of dog more similarly to veterinary faculty and staff. Further, when undergraduates had clinical experience, they also rated certain dog breeds in a similar way to the veterinary students and professionals. Our findings suggest that veterinary education and clinical experiences influence pain sensitivity ratings across dog breeds. Future research should identify how these pain sensitivity beliefs are communicated and whether these beliefs affect recognition and treatment of pain by veterinarians.

Pain sensitivity differs between dog breeds but not in the way veterinarians believe

Background

Veterinarians hold distinct breed-specific pain sensitivity beliefs that differ from the general public but are highly consistent with one another. This is remarkable as there is no current scientific evidence for biological differences in pain sensitivity across dog breeds. Therefore, the present study evaluated whether pain sensitivity thresholds differ across a set of dog breeds and, if so, whether veterinarians' pain sensitivity ratings explain these differences or whether these ratings are attributed to behavioral characteristics.

Methods

Pain sensitivity thresholds [using quantitative sensory testing (QST) methods] and canine behaviors (using owner questionnaires and emotional reactivity tests) were prospectively measured across selected dog breeds. Adult, healthy dogs from 10 dog breeds/breed types were recruited, representing breeds subjectively rated by veterinarians as high (chihuahua, German shepherd, Maltese, Siberian husky), average (border collie, Boston terrier, Jack Russell terrier), or low (golden retriever, pitbull, Labrador retriever) pain sensitivity. A final sample of 149 dogs was included in statistical analyses.

Results

Veterinarians' pain sensitivity ratings provided a minimal explanation for pain sensitivity thresholds measured using QST in dogs; however, dog breeds did differ in their pain sensitivity thresholds across the QST methods evaluated. Breed differences were observed for some aspects of emotional reactivity tests; however, these behavioral differences did not explain the differences in pain sensitivity thresholds found. Veterinarians' pain sensitivity ratings were positively associated with dog approach scores for the disgruntled stranger test suggesting that the way dogs greet strangers may be a factor influencing veterinarians' ratings of pain sensitivity across dog breeds.

Conclusions and clinical relevance

Overall, these findings highlight a need to investigate biological mechanisms that may explain breed differences in pain sensitivity because this may inform pain management recommendations. Further, future research should focus on when and how these breed-specific pain sensitivity beliefs developed in veterinarians, as veterinarians' beliefs could impact the recognition and treatment of pain for canine patients.

How gender affects the decoding of facial expressions of pain

OBJECTIVES

Gender has been suggested to play a critical role in how facial expressions of pain are perceived by others. With the present study we aim to further investigate how gender might impact the decoding of facial expressions of pain, (i) by varying both the gender of the observer as well as the gender of the expressor and (ii) by considering two different aspects of the decoding process, namely intensity decoding and pain recognition.

METHODS

In two online-studies, videos of facial expressions of pain as well as of anger and disgust displayed by male and female avatars were presented to male and female participants. In the first study, valence and arousal ratings were assessed (intensity decoding) and in the second study, participants provided intensity ratings for different affective states, that allowed for assessing intensity decoding as well as pain recognition.

RESULTS

The gender of the avatar significantly affected the intensity decoding of facial expressions of pain, with higher ratings (arousal, valence, pain intensity) for female compared to male avatars. In contrast, the gender of the observer had no significant impact on intensity decoding. With regard to pain recognition (differentiating pain from anger and disgust), neither the gender of the avatar, nor the gender of the observer had any affect.

CONCLUSIONS

Only the gender of the expressor seems to have a substantial impact on the decoding of facial expressions of pain, whereas the gender of the observer seems of less relevance. Reasons for the tendency to see more pain in female faces might be due to psychosocial factors (e.g., gender stereotypes) and require further research.

Gender and ethnicity bias in medicine: a text analysis of 1.8 million critical care records

Gender and ethnicity biases are pervasive across many societal domains including politics, employment, and medicine. Such biases will facilitate inequalities until they are revealed and mitigated at scale. To this end, over 1.8 million caregiver notes (502 million words) from a large US hospital were evaluated with natural language processing techniques in search of gender and ethnicity bias indicators. Consistent with nonlinguistic evidence of bias in medicine, physicians focused more on the emotions of women compared to men and focused more on the scientific and bodily diagnoses of men compared to women. Content patterns were relatively consistent across genders. Physicians also attended to fewer emotions for Black/African and Asian patients compared to White patients, and physicians demonstrated the greatest need to work through diagnoses for Black/African women compared to other patients. Content disparities were clearer across ethnicities, as physicians focused less on the pain of Black/African and Asian patients compared to White patients in their critical care notes. This research provides evidence of gender and ethnicity biases in medicine as communicated by physicians in the field and requires the critical examination of institutions that perpetuate bias in social systems.

The Experiences of Persistent Pain Among Women With a History of Intimate Partner Violence: A Systematic Review

Women experience persistent pain at higher rates than men; however, women are less likely to be provided with adequate or appropriate care and more likely to have their pain experiences dismissed. The purpose of this review is to consider the complex interaction of the biopsychosocial factors in the experience of persistent pain in order to inform improved models of care. Given persistent pain is among the most frequently reported health consequences of intimate partner violence (IPV), this review focused on studies exploring the association between persistent pain and IPV. Three reviewers independently and systematically searched seven databases. Qualitative and quantitative studies describing the association between IPV and persistent pain published between January 2000 and June 2018 were included. Twelve studies met the inclusion criteria. The included studies demonstrated that a history of IPV places an additional burden on women who experience persistent pain that cannot be explained by an underlying psychological condition. Health care practitioners should be aware of this phenomena to ensure diagnosis, assessment, and treatment plans are targeted accordingly. Future policy directives and research should account for and seek to elucidate this additional burden.

Evaluation of Pain After Mohs Micrographic Surgery: A Prospective Study

BACKGROUND

Mohs micrographic surgery (MMS) is a widely used technique for removal of cutaneous tumors. The procedure is well-tolerated with little surgical or postoperative pain.

OBJECTIVE

This study examined pain levels after Mohs surgery throughout the first week of recovery and the relation to patient demographics, lesion characteristics, surgery details, and postoperative analgesia.

METHODS

A 2-year prospective observational study included patients who underwent MMS. Patients rated the severity of postoperative pain once daily until removal of sutures and documented analgesics used. Analyses of patient and lesion characteristics along with reconstruction methods were conducted.

RESULTS

A total of 2,178 patients were included in the study. Pain levels were strongest on the first postoperative day (POD) and were significantly different between genders on POD 3. Site of skin lesion, method of reconstruction, and number of stages of MMS were significantly related to postoperative pain levels on univariate and multivariate analyses. Postoperative consumption of analgesics differed significantly between men and women and was not correlated to age.

CONCLUSION

Mohs surgery is generally nonpainful and is well-tolerated by men and women across all ages. The site of the lesion and method of reconstruction are the major determinants affecting the perception of pain.

Effects of Exercise-induced Hypoalgesia and Its Neural Mechanisms

PURPOSE

Exercise-induced hypoalgesia is frequently documented in the literature. However, the underlying neural mechanism of this phenomenon remains unclear. Here, we explored the effects of different intensities of isometric exercise on pain perception with a randomized controlled design and investigated its neural mechanisms through tracing the dynamic changes of heat-evoked brain responses.

METHODS

Forty-eight participants were randomly assigned to one of the three groups with different exercise intensities (i.e., high, low, and control). Their subjective pain reports and brain responses elicited by heat stimuli before and after exercise were assessed.

RESULTS

We observed 1) the increased pressure pain thresholds and heat pain thresholds on the dorsal surface of the hand and the biceps brachii muscle of the exercised limb (closed to the contracting muscle), and the decreased pressure pain ratings at the indexed finger of the unexercised limb; 2) more reduction of pain sensitivity on both the biceps brachii muscle and the dorsal surface of the hand induced by the high-intensity isometric exercise than the low-intensity isometric exercise; and 3) both the high-intensity and the low-intensity isometric exercise induced the reduction of N2 amplitudes and N2-P2 peak-to-peak amplitudes, as well as the reduction of event-related potential magnitudes elicited by the heat stimuli on the exercised limb.

CONCLUSIONS

The hypoalgesic effects induced by the isometric exercise were not only localized to the moving part of the body but also can be extended to the distal part of the body. The exercise intensities play a vital role in modulating these effects. Exercise-induced hypoalgesia could be related to the modulation of nociceptive information transmission via a spinal gating mechanism and also rely on a top-down descending pain inhibitory mechanism.

Community Capacity Building for HIV and Addiction Service Integration: An Intervention Trial in Vietnam

Scientific findings and policy guidelines recommend integrating HIV and drug addiction prevention and care into community-based settings. Systematic capacity-building efforts are warranted to provide technical support for community health workers and improve their confidence in the integrated service provision. An intervention trial was conducted between 2018 and 2019 with 120 community health workers (CHW) from 60 communes in Vietnam’s four provinces. The 60 intervention CHW received in-person training to enhance their HIV/addiction-related service knowledge and skills. Online support groups were established between trained CHW and local HIV and addiction specialists. The intervention outcomes were assessed using mixed-effects regression models with the data collected at baseline and every 3 months for 1 year. Adjusted analyses showed that intervention CHW reported a significant increase in the interaction with other treatment providers than the control group at 6 months and remained at the 12-month follow-up. The difference in the improvement of confidence in HIV/addiction-related service delivery between the intervention and control groups was significant at 6-month but became insignificant at the 12-month. Male CHW were more confident in providing services than female CHW at baseline, and gender differences in the changing patterns were observed over time. This capacity-building intervention demonstrated promising outcomes on CHW inter-agency collaborations and confidence in service delivery. Gender divides in healthcare professionals should be attended to in future studies.

Attentional Biases Towards Body Expressions of Pain in Men and Women

This study investigated whether there are gender differences in attention to bodily expressions of pain and core emotions. Three experiments are reported using the attentional dot probe task. Images of men and women displaying bodily expressions, including pain, were presented. The task was used to determine whether participants' attention was drawn towards or away from target expressions. Inconsistent evidence was found for an attentional bias towards body expressions, including pain. While biases were affected by gender, patterns varied across the Experiments. Experiment 1, which had a presentation duration of 500 ms, found a relative bias towards the location of male body expressions compared to female expressions. Experiments 2 and 3 varied stimulus exposure times by including both shorter and longer duration conditions (e.g., 100 vs. 500 vs. 1250 ms). In these experiments, a bias towards pain was confirmed. Gender differences were also found, especially in the longer presentation conditions. Expressive body postures captured the attention of women for longer compared to men. These results are discussed in light of their implications for why there are gender differences in attention to pain, and what impact this has on pain behaviour. PERSPECTIVE: We show that men and women might differ in how they direct their attention towards bodily expressions, including pain. These results have relevance to understanding how carers might attend to the pain of others, as well as highlighting the wider role that social-contextual factors have in pain.

The gender context of pain

Pain is a major source of global suffering, with women bearing the greatest burden. Alongside biology, psychological and social factors, including gender, help explain these differences. However, there has been no direct attempt to develop a unified social psychological model of men and women's pain. By drawing on approaches to both gender and pain, a gender context model of pain is presented. It proposes that pain is partly influenced by the gender context in which it occurs, which operates at both individual and interpersonal levels. The model is used to structure an appraisal of the existing evidence around gender and pain, and explore whether the model helps explain why such variation occurs. It is argued that despite evidence for an association between gender and pain, there are empirical gaps that need to be addressed. Implications and directions for future investigations into sex, gender and pain are considered.

Health social workers' assessments as part of a specialized pain rehabilitation: a clinical data-mining study

This study examines how health social workers (HSWs) assess the rehabilitation needs of patients with long-term pain. Data were extracted from 66 patient assessments through a retrieval form based on the International Classification of Functioning, Disability, and Health. The assessments included information about relations, work, and recreation. Stress management, problem solving, self-care, participation in community life, and providing personal care were missing in parts of or all assessments. Differences in assessments suggest that information was registered based on traditional gender roles and age. Therefore, HSWs need standardized assessment tools to ensure that assessments are relevant for all patients with long-term pain irrespective of gender or age.

Exploring the role of gender and gendered pain expectation in physiotherapy students

Introduction: Gender and gender role pain expectations may influence how health care providers interact with and manage their patients' symptoms. Purpose: The purpose of this study was to describe gendered traits and gender role pain expectations among physical therapy students. Method: A survey assessing gendered traits and gender role expectations in relation to pain was completed by a sample of 171 physical therapy students (120 women, 51 men). Data were analyzed using descriptive statistics and differences between men and women were tested with chi-square or Kruskal-Wallis. Results: Men and women in physical therapy training were not different on 13 out of 16 of the gendered traits. The exceptions were that men rated themselves as more "decisive" compared to women (mean rank = 103.8 vs. mean rank = 78.4, P = 0.001) and women rated themselves as more "emotional" (mean rank = 91.95 vs. mean rank = 72.01, P = 0.009) and more "nurturing" (mean rank = 90.89 vs. mean rank = 72.91, P = 0.020). No significant differences were found in terms of gendered expectations of pain sensitivity, endurance, or in terms of personal experience of pain between the men and women in the sample. However, the majority (75%) of participants reported that women were more willing to report pain compared to men. Finally, both groups rated themselves as no different in handling pain compared to a typical man or woman. Conclusion: In conclusion, men and women in training to be physical therapists demonstrate similar gendered trait profiles and little gender bias in relation to pain expectations.
