Reliability, validity, and responsiveness of multidimensional pain assessment tools used in postoperative adult patients: a systematic review of measurement properties

Which Patients With Chronic Pain Do The Primary Care Refers to a Tertiary Hospital in a Developing Country? Experience From a University Hospital

PURPOSE

The study aimed to profile patients with uncontrolled chronic pain referred from primary care to a tertiary hospital in a developing country, and identify factors associated with pain intensity, interference, and its link with mental health.

DESIGN

Cross-sectional design.

METHODS

Data from 906 adult patients with nonmalignant chronic pain during their first visit to the multidisciplinary pain center at the State University of Rio de Janeiro in 2019 were used. The brief pain inventory and the Hospital Anxiety and Depression Scale questionnaire assessed pain intensity, its impact on daily activity, and symptoms of anxiety and depression.

RESULTS

The population was predominantly female (68.8%), over 50 (66.3%), with less than 11 years of education (86.5%), and 75.2% were overweight or obese. Most (81.9%) reported moderate or severe pain, significantly interfering with daily activities (>50%). The lower back was the most commonly affected site. Widespread pain was present in 43.6% of patients. High scores for anxiety (67.4%) and depression (52.2%) were observed. Severe pain was predominantly seen in middle-aged women and individuals with high levels of anxiety and depression.

CONCLUSION

Patients with uncontrolled chronic pain referred from primary care to a tertiary hospital were predominantly female, overweight or obese, and exhibited a high prevalence of depression and anxiety. Their pain significantly interfered with daily activities.

CLINICAL IMPLICATIONS

The study provides valuable insight into the biopsychosocial characteristics of uncontrolled chronic pain patients in primary care, emphasizing the importance of implementing multidisciplinary approaches to manage chronic pain effectively within primary care settings.

Prevalence and risk factors of fatigue and its association with quality of life among patients with chronic pancreatitis: A cross-sectional study

BACKGROUND

Fatigue is a debilitating symptom found in various chronic diseases and is associated with more severe symptoms and worse quality of life (QoL). However, this symptom has not been adequately addressed in chronic pancreatitis (CP), and there have been no studies on fatigue in patients with CP.

METHODS

This cross-sectional study was conducted at the Changhai Hospital in Shanghai, China. Data on the patients' sociodemographic, disease, and therapeutic characteristics were collected. Fatigue was assessed using the Multidimensional Fatigue Inventory-20. QoL was assessed utilizing the European Organization for the Research and Treatment of Cancer of QoL questionnaire (EORTC-QLQ-C30). Sleep quality, anxiety and depression, and pain was assessed using Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, and the Brief Pain Inventory, respectively.

RESULTS

The prevalence of fatigue among Chinese patients with CP was 35.51 % (87/245). Multivariate analysis showed that steatorrhea (OR = 2.638, 95 % CI: 1.117-6.234), history of smoking (OR = 4.627, 95 % CI: 1.202-17.802), history of endoscopic treatment (OR = 0.419, 95 % CI: 0.185-0.950), depression (OR = 5.924, 95 % CI: 2.462-14.255), and sleep disorder (OR = 6.184, 95 % CI: 2.543-15.034) were influencing factors for the presence of fatigue. The scores for global health and all functional dimensions in the EORTC-QLQ-C30 significantly decreased, whereas the scores for all symptom dimensions significantly increased in patients with fatigue.

CONCLUSIONS

This study indicated that Fatigue is a common symptom and has a negative impact on the QoL of patients with CP. Steatorrhea, smoking history, endoscopic treatment, depression, and sleep disorders were associated with fatigue.

Utility of unidimensional and functional pain assessment tools in adult postoperative patients: a systematic review

BACKGROUND

We aimed to appraise the evidence relating to the measurement properties of unidimensional tools to quantify pain after surgery. Furthermore, we wished to identify the tools used to assess interference of pain with functional recovery.

METHODS

Four electronic sources (MEDLINE, Embase, CINAHL, PsycINFO) were searched in August 2020. Two reviewers independently screened articles and assessed risk of bias using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist.

RESULTS

Thirty-one studies with a total of 12 498 participants were included. Most of the studies failed to meet the methodological quality standards required by COSMIN. Studies of unidimensional assessment tools were underpinned by low-quality evidence for reliability (five studies), and responsiveness (seven studies). Convergent validity was the most studied property (13 studies) with moderate to high correlation ranging from 0.5 to 0.9 between unidimensional tools. Interpretability results were available only for the visual analogue scale (seven studies) and numerical rating scale (four studies). Studies on functional assessment tools were scarce; only one study included an 'Objective Pain Score,' a tool assessing pain interference with respiratory function, and it had low-quality for convergent validity.

CONCLUSIONS

This systematic review challenges the validity and reliability of unidimensional tools in adult patients after surgery. We found no evidence that any one unidimensional tool has superior measurement properties in assessing postoperative pain. In addition, because promoting function is a crucial perioperative goal, psychometric validation studies of functional pain assessment tools are needed to improve pain assessment and management.
