Evaluation of Pain Assessment and Management in Critically Ill Intubated Patients in a Referral University Hospital in Iran

Pain management of adult sedated and ventilated patients in the intensive care units: A survey with free text responses

BACKGROUND

Pain management of sedated and ventilated patients in intensive care units lacks consistency.

OBJECTIVES

To investigate nurses' training, governance, practices, knowledge and attitudes relating to pain management in consideration of published guidelines and explore nurses' perspectives.

METHODS

A survey design, using an online questionnaire with free text responses, was employed. Quantitative and qualitative data from nurses working across different hospitals were collated and saved on Qualtrics platform. Quantitative data were analysed non-parametrically and narrative responses thematically. CROSS and SRQR reporting guidelines were adhered to.

OUTCOME MEASURES

Demographics, training, governance, clinical practice, knowledge, and attitudes.

RESULTS/FINDINGS

108 nurses participated with ninety-two completed surveys analysed. Analgesia was used to complete nursing tasks regardless of comfort needs (n = 49, 53.3 %). Changes in vital signs prompted opioid administration (n = 48, 52.1 %). Choice of analgesia depended on doctor's preference (n = 63, 68.5 %). Non-opioid therapy was administered before opioids (n = 42, 45.7 %). Sedatives were used to alleviate agitation(n = 50,54.3 %). No statistically significant difference in nurses' knowledge existed between hospitals. Weak positive relationship: r = [0.081], p = [0.441] between "knowledge scores" and "years of ICU experience" and weak negative relationship r = [-0.119], p = [0.260] between "knowledge scores" and "hours of clinical practice" was detected. Lack of training, resources, policies, high patient acuity and casual employment were acknowledged barriers to pain management. Two overarching themes emerged from narrative responses: "Pain assessment, where is it?" And "Priorities of critical illness."

CONCLUSION

The study uncovered pain management situation and examined nurses' demographics, training, governance, practices, knowledge and attitudes. Narrative responses highlighted barriers to pain management.

IMPLICATIONS FOR CLINICAL PRACTICE

Health organisations should provide education, institute governance and develop policies to inform pain management. Nurses' role encompasses updating knowledge, adhering to interventions and overcoming biases. This subsequently manifests as improvement in patient outcomes.

The Association between Socio-Demographic Characteristics and Using Pain Assessment Tools among Critically Ill Patients

Background and Objectives: Pain is still undertreated among ICU patients, especially cognitively impaired patients. Nurses play a crucial role in their management. However, previous studies found that nurses had insufficient knowledge about pain assessment and management. Some nurses' socio-demographic characteristics, such as being female; age; years of experience; type of unit, either medical or surgical; education level; years of nursing experience; qualification; position; and hospital level, were found to be associated with their practices of pain assessment and management. This study aimed to examine the association between nurses' socio-demographic characteristics and the use of pain assessment tools for critically ill patients. Materials and Methods: A convenience sample of 200 Jordanian nurses responded to the Pain Assessment and Management for the Critically Ill questionnaire to achieve the study's aim. Results: The type of hospital, academic qualification, years of experience as a critical care nurse, and hospital affiliation were significantly associated with increased use of self-report pain assessment tools for verbal patients, while the type of hospital and hospital affiliation was significantly associated with an increased use of observational pain assessment tools for nonverbal patients. Conclusion: Examining the association between socio-demographic characteristics and the use of pain assessment tools for critically ill patients is essential for quality pain practice.

A nationwide study on consumption of opioid analgesics in Iran from 2000 to 2018

BACKGROUND

Opioid analgesics play a unique role in pain management. National opioid consumption studies could provide indirect evidence of pain management in a country. National, regional, and global opioid consumption have been studied in other countries so far; however, conducting a focused study to illuminate the consumption of opioid analgesics over the past decades in Iran seemed necessary.

AIM

The main objective of this study was to determine the consumption of opioid analgesics and explore the trend of their use during 19 years in Iran.

METHOD

Iran pharmaceutical wholesale data were used to extract the annual consumption figures of the opioid analgesics in group N02A of the World Health Organization (WHO) Anatomical Therapeutic Chemical classification and were available in Iran (morphine, fentanyl, pethidine, and oxycodone as strong opioids and, tramadol and pentazocine as weak opioids), from 2000 to 2018. Using Defined Daily Dose (DDD) by WHO and Oral Morphine Equivalent (OMEQ), the amount of annual consumption was determined in DDD/1000 inhabitants/Day (DID) and OMEQ (mg)/1000 inhabitants/Day (OID).

RESULTS

Total opioid analgesic utilization based on DID and OID increased 31.12-fold (from 0.0196 to 0.61) and 21.06-fold (from 1.97 to 41.5 mg) over 19 years, respectively with a significant sharp increase from 2003 to 2006 (ß = 1.78 (DID), P value < 0.001). Medications that constituted 70% of annual opioid analgesics utilization were morphine in 2000, compared to tramadol in 2018. The annual weak and strong opioids share were 86.7% and 13.2% in 2018, respectively.

CONCLUSION

Despite considerable growth in the consumption of opioid analgesics in Iran over nearly two decades, the consumption amount remained low, which might signal sub-optimal pain management. On the other hand, misuse and abuse seem to be the main reason behind significant increases in the consumption of opioid analgesics with less controlled distribution.

Validity of Pulse Oximetry-derived Peripheral Perfusion Index in Pain Assessment in Critically Ill Intubated Patients

OBJECTIVES

Evaluation of pain in critically ill intubated patients is difficult and subjective. This study aimed to evaluate the accuracy of oximetry-derived peripheral perfusion index (PPI) in pain assessment in critically ill intubated patients using the behavioral pain scale (BPS) as a reference.

MATERIALS AND METHODS

This prospective observational study included 35 adult mechanically ventilated surgical patients during their first 2 postoperative days in the intensive care unit. Values of PPI, BPS, Richmond Agitation Sedation Scale (RASS), heart rate, and blood pressure were obtained before and after a standard painful stimulus (changing the patient position) and the ratio between the second and the first reading was calculated to determine the change (Δ) in all variables. The outcomes were the correlation between ΔBPS and ΔPPI as well as other hemodynamic parameters. The ability of the PPI to detect pain (defined as BPS ≥6) was analyzed using the area under receiver operating characteristic curve.

RESULTS

Paired readings were obtained from 35 patients. After the standard painful stimulus, the PPI decreased while the BPS and the Richmond agitation sedation scale increased. The Spearman correlation coefficient (95% confidence interval) between Δ PPI and Δ BPS was 0.41 (0.09-0.65). PPI values showed poor accuracy in detecting pain with area under receiver operating characteristic curve (95% confidence interval): 0.65 (0.53-0.76), with best cutoff value of ≤2.7.

CONCLUSION

The PPI decreased after application of a standard painful stimulus in critically ill intubated patients. ∆PPI showed a low correlation with ∆BPS, and a PPI of ≤2.7 showed a low ability to detect BPS ≥6. Therefore, PPI should not be used for pain evaluation in critically ill intubated surgical patients.
