Developing and validating a Japanese version of the Assessment of Pain in Elderly People with Communication Impairment

Validation of the Japanese version of Algoplus® for the assessment of acute postoperative pain in older patients with cancer

AIM

This study aimed to validate a Japanese version of the Algoplus® tool by assessing postoperative pain in older Japanese patients with cancer and examining the scale's psychometric properties.

METHODS

After translating Algoplus® into Japanese, we conducted a cross-sectional study of patients aged 65 years or older who underwent surgery to remove malignant tumors. Two registered nurse-certified investigators used the Numerical Rating Scale, the Japanese version of Algoplus®, and the Japanese version of the Abbey Pain Scale before and after analgesic use on postoperative days 3 and 5 to evaluate response to pharmacologic therapy. Validity was tested by a correlation analysis between the Japanese version of Algoplus®, two pain scales, and nine hypotheses related to demographic variables and surgical invasions. The Kuder-Richardson-20 test and Cohen's Kappa coefficient were used for internal consistency and inter-rater reliability, respectively.

RESULTS

The total score of the Japanese version of Algoplus® showed strong to moderate correlations with the two pain scales. Demographic characteristics were not associated with the total score of the Japanese version, but significant correlations with operative time and postoperative analgesia administration existed. The scale demonstrated good internal consistency (Kuder-Richardson-20 α: .70) and inter-rater reliability (Kappa coefficient .72). The total score of the Japanese version decreased significantly after analgesic use in both postoperative assessments.

CONCLUSIONS

The Japanese version of Algoplus® is a reliable and valid instrument for nurses to easily assess acute postoperative pain in older Japanese patients with cancer and shows good responsiveness for detecting the change in pain status.

Pain assessment tools in adults with communication disorders: systematic review and meta-analysis

BACKGROUND

Verbal communication is the "gold standard" for assessing pain. Consequently, individuals with communication disorders are particularly vulnerable to incomplete pain management. This review aims at identifying the current pain assessment instruments for adult patients with communication disorders.

METHODS

A systematic review with meta-analysis was conducted on PubMed, PEDRO, EBSCOhost, VHL and Cochrane databases from 2011 to 2023 using MeSH terms "pain assessment, "nonverbal communication" and "communication disorders" in conjunction with additional inclusion criteria: studies limited to humans, interventions involving adult patients, and empirical investigations.

RESULTS

Fifty articles were included in the review. Seven studies report sufficient data to perform the meta-analysis. Observational scales are the most common instruments to evaluate pain in individuals with communication disorders followed by physiological measures and facial recognition systems. While most pain assessments rely on observational scales, current evidence does not strongly endorse one scale over others for clinical practice. However, specific observational scales appear to be particularly suitable for identifying pain during certain potentially painful procedures, such as suctioning and mobilization, in these populations. Additionally, specific observational scales appear to be well-suited for certain conditions, such as mechanically ventilated patients.

CONCLUSIONS

While observational scales dominate pain assessment, no universal tool exists for adults with communication disorders. Specific scales exhibit promise for distinct populations, yet the diverse landscape of tools hampers a one-size-fits-all solution. Crucially, further high-quality research, offering quantitative data like reliability findings, is needed to identify optimal tools for various contexts. Clinicians should be informed to select tools judiciously, recognizing the nuanced appropriateness of each in diverse clinical situations.

Measuring Pain in Aphasia: Validity and Reliability of the PACSLAC-D

BACKGROUND

Post-stroke pain in patients with an inability to communicate is not systematically assessed and therefore not sufficiently treated. This stresses the need to study pain assessment instruments that do not require good communication skills.

AIM

To examine the validity and reliability of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate - Dutch version (PACSLAC-D) in stroke patients with aphasia.

METHOD

Sixty stroke patients (mean age 79.3 years, standard deviation [SD] 8.0), of whom 27 had aphasia were observed during rest, activities of daily living (ADL), and physiotherapy using the Pain Assessment Checklist for Seniors with Limited Ability to Communicate - Dutch version (PACSLAC-D). The observations were repeated after two weeks. To examine convergent validity, correlations between the PACSLAC-D, self-report pain scales, and the clinical judgment of a health care professional (pain present yes/no) were used. To examine discriminative validity, differences in pain were investigated between rest and ADL, in patients who use pain medication and those who do not, and in patients with and without aphasia. Internal consistency and test-retest reliability were assessed to determine reliability.

RESULTS

Convergent validity failed to meet the acceptable threshold during rest but was adequate during ADL and physiotherapy. Discriminative validity was only adequate during ADL. The internal consistency was 0.33 during rest, 0.71 during ADL, and 0.65 during physiotherapy. Test-retest reliability varied from poor during rest (intraclass correlation coefficient [ICC] = 0.07; 95% confidence interval [CI]: -0.40-0.51) to excellent during physiotherapy (ICC = 0.95; 95% CI: 0.83-0.98).

CONCLUSIONS

The PACSLAC-D captures pain in patients with aphasia who are unable to self-report, during ADL and physiotherapy, but may be less accurate during rest.

Validation of Pain Assessment Checklist for Seniors with Limited Ability to Communicate-II (PACSLAC-II) in Iranian older adults with dementia living in nursing homes

BACKGROUND

Some dementia patients can self-report pain although the reports are not valid in severe dementia. Observational scales have been developed for pain assessment in these patients. This study aimed to assess the psychometric properties of the Persian version of Pain Assessment Checklist for Seniors with Limited Ability to Communicate-II (PACSLAC-II).

METHODS

This validation study was conducted on 138 older adults with dementia suffering from chronic pain who lived in nursing homes. The PACSLAC-II Persian version was applied through observations during activity and rest. Reliability of the PACSLAC-II was evaluated by Cronbach's alpha and intra-class correlation coefficients. Construct validity was determined by confirmatory factor analysis, divergent and convergent validity. The Spearman's rank correlation between PACSLAC-II scores and Faces Pain Scale was calculated for concurrent validity. Known-group validity during activity and rest was calculated by Wilcoxon signed ranks test.

RESULTS

Cronbach's alpha coefficient for facial expression (0.82), verbalisation (0.72), and body movement (0.84) subscales indicated good internal consistency. The intra-class correlation coefficients between two raters was 0.76 and in three times evaluation, the value was 0.76. Convergent validity with Iranian Brief Pain Inventory and divergent validity with 15-item Geriatric Depression Scale confirmed the construct validity of PACSLAC-II. Three factors structure of PACSLAC-II was approved, and most of the variance was explained by facial expressions. The PACSLAC-II can discriminate between pain and non-pain events and has a moderate correlation with Faces Pain Scale (r = 0.33).

CONCLUSIONS

PACSLAC-II Persian version is a valid and reliable scale for pain assessment in older adults with dementia.

[Validity and reliability of the Korean version of the pain assessment checklist for seniors with limited ability to communicate]

PURPOSE

This study was done to develop and test the validity and reliability of the Korean version of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC-K) in assessing pain of elders with dementia living in long-term care facilities.

METHODS

The PACSLAC-K was developed through forward-backward translation techniques. Survey data were collected from 307 elders with dementia living in 5 long-term care facilities in Korea. Data were analyzed using descriptive statistics, Pearson correlation, Spearman's rho, paired t-test, ROC (receiver operation characteristic) curve with the SPSS/WIN (20.0) program.

RESULTS

The PACSLAC-K showed high internal consistency (.90), inter-rater reliability (.86), intra-rater reliability (.93), and high concurrent validity (.74) in paired t-test with PAINAD. Discriminant validity also showed a significant difference compared with no pain. The PACSLAC-K showed a sensitivity of .93, specificity of .88, and Area Under the Curve of .95 in the ROC curve.

CONCLUSION

The findings of this study demonstrate that PACSLAC-K is useful in assessing pain for elders with dementia living in long-term care facilities.
