Pain in Advanced Stages of Dementia: The Perspective of Medical Students

Rasch development and validation of a new faces scale for measuring pain, and its comparison with a gold standard: the Balparda-Herrera Pain Scale

Aim: Faces pain scales are widely used to measure pain. So far, no faces pain scale has ever been constructed by Rasch modeling. Hence the authors aimed to construct a new scale by this method. Methods: Rasch modeling was used to provide an initial calibration and development of the 'Balparda-Herrera Pain Scale' (BHPS) and this scale was compared with the existing Faces Pain Scale - Revised. The scale was later refined. Results: Both the existing scale and the initial version of the BHPS required category collapsing. Statistical tests demonstrated an excellent concordance between both scales. The final version of the BHPS was found to behave excellently and to be capable of adequately measuring pain. Conclusion: The BHPS provides an excellent instrument for measuring pain in the adult population.

Pain in People with Advanced Dementia: The Opinions of Kazakh Medical Students

Purpose

The medical students’ attitude toward pain in people with advanced dementia, while constituting an important factor in care, has rarely been assessed to date. The aim of our study was thus to perform such assessment in medical students in Kazakhstan, to enable an improvement of the existing curriculum (like we previously did in Poland).

Materials and Methods

We analyzed the knowledge about pain using a short anonymous questionnaire, which was completed by 112 students of the Medical University of Aktobe, Kazakhstan.

Results

On average, students listed symptoms of 1.4 ± 1.2 (out of 6 analyzed) pain areas (median 2.0). The symptoms related to changes in mental status were suggested the most often (57 students: 50.9%). The students who indicated these symptoms also listed a higher number of symptoms from the remaining domains (1,1 ± 1.0 [median 1.0] vs 0.6 ± 0.8 [median 0.0]; p<0.01). Observational methods in the assessment of the severity of pain in people with dementia were indicated by 44 students (39.3%), but only one participant (0.9%) was able to name an observational scale for pain assessment. Correct answers regarding pain treatment rules were presented by 18 students (16.0%), and the answers of the next 47 participants (42.0%) were very general but suggested the same treatment no matter what the cognitive status.

Conclusion

The study revealed gaps in the knowledge of Kazakh medical students regarding pain in advanced stages of dementia. Demographic changes, combined with the coexistence of pain with dementia, indicate that medical students worldwide must have sufficient knowledge and skills to adequately care for the continually growing number of people with these conditions. It is imperative in countries like Kazakhstan, where the dementia burden was unrecognized until now, but it will blow up in the near future.

Acute and Chronic Pain Learning and Teaching in Medical School-An Observational Cross-Sectional Study Regarding Preparation and Self-Confidence of Clinical and Pre-Clinical Medical Students

Background and objectives: Adequate pain management is a major challenge of public health. The majority of students graduating from medical schools has insufficient education and experience with patients suffering pain. Not enough is being taught regarding pain in non-verbal patients (children, critically ill in the intensive care unit, demented). Chronic pain is the most difficult to optimize and requires appropriate preparation at the level of medical school. Our aim was to evaluate attitudes, expectations and the actual knowledge of medical students at different levels of their career path regarding the assessment and treatment of acute and chronic pain. Materials and Methods: We performed an observational cross-sectional study that was based on a survey distributed among medical students of pre-clinical and post-clinical years at the Pomeranian Medical University in Szczecin, Poland. The survey included: demographic data, number of hours of formal pain teaching, actual knowledge of pain assessment, and pain treatment options in adults and children. Results: We received responses from 77/364 (21.15%) students and 79.2% of them rated the need to obtain knowledge regarding pain as very important (10/10 points). Post-clinical group declared having on average 11.51 h of acute pain teaching as compared to the 7.4 h reported by the pre-clinical group (p = 0.012). Graduating students also reported having significantly more classes regarding the treatment of chronic pain (6.08 h vs. 3.79 h, p = 0.007). The average level of comfort in the post-clinical group regarding treatment of acute pain was higher than in the pre-clinical group (6.05 vs. 4.26, p = 0.006), similarly with chronic pain treatment in adults (4.33 vs. 2.97, p = 0.021) and with pain treatment in children (3.14 vs. 1.97, p = 0.026). Conclusions: This study shows that education about pain management is a priority to medical students. Despite this, there continues to be a discrepancy between students’ expectations and the actual teaching and knowledge regarding effective pain management, including the vulnerable groups: chronic pain patients, children, and critically ill people.
