Effects of the discharge plan on the caregiving load of people with chronic disease: Quasi-experimental study

OBJECTIVE

To determine the effect of an anticipated care plan, structured around hospital discharge (PC-AH-US), regarding the caregiving load of people with NTCD residing in Colombia, 2019-2021.

METHOD

This is a quasi-experimental study with pre- and post-intervention measurements. It includes 1170 participants who represented 585 chronic disease patient-caregiver pairs. We compared the PC-AH-US intervention, to the regular intervention.

RESULTS

The PC-AH-US intervention group showed better results in all dimensions when compared to the regular intervention group: Awareness 8.7 (SD: 0.7) and 6.8 (SD: 1.7); Acknowledgement of their unique conditions 11.3 (SD: 1.0) and 9.4 (SD: 1.8); Capacity to fulfill care tasks 8.8 (SD: 0.7) and 7.5 (SD: 1.5); Wellbeing 11.4 (SD: 0.90) and 8.87 (SD: 2.3); Anticipation 5.88 (SD: 0.4) and 4.7 (SD: 1.1) and Support Network 11.4 (SD: 0.8) and 9.9 (SD: 2.5).

CONCLUSION

The PC-AH-US intervention group showed a statistically significant decrease in the caregiving load for people with NTCD (p < 00). There were no significant institutional differences in readmissions or deaths. The PC-AH-US intervention backs institutional policies meant to care for people with NTCD.

The Pre-Operative Evaluation Clinic: An Underutilized Service in Optimizing Analgesic Outcomes in Patients on Buprenorphine, Methadone, and Naltrexone for Substance Use Disorder or Chronic Pain

Background

Patients receiving methadone, buprenorphine, and naltrexone for either chronic pain or substance use disorder (SUD) pose perioperative challenges. Due to their complex pharmacology, perioperative recommendations continue to evolve. Deviations from these recommendations may result in worse perioperative outcomes. A formal preoperative evaluation (POE) and optimization of patients on these medications are recommended to address these concerns.

Methods

A single-center retrospective electronic health record review was performed with adult patients on methadone, buprenorphine, and naltrexone undergoing elective surgery between January 1, 2010 and December 31, 2020. The primary outcome of interest was the percentage of patients referred to the POE clinic for evaluation prior to the scheduled elective surgery. In addition, we assessed differences in variables (perioperative opioid, hospital length of stay, perioperative multimodal analgesics, perioperative complications, inpatient pain service consult, readmission within 30 days, cancellation of surgery, addiction medicine consult) based on POE clinic evaluation. This analysis was performed separately for patients prescribed these medications for SUD versus chronic pain. Continuous outcomes were analyzed using linear regression with generalized estimating equations (GEE) and robust variance estimates.

Results

A total of 714 patients were included in the final analysis, of which 572 (80%) took buprenorphine, methadone, or naltrexone for chronic pain and 142 (20%) took these medications for SUD. Within the chronic pain and SUD subpopulations, 193 (34%) and 35 (25%) patients had formal POE clinic assessments, respectively. Among those taking these medications for chronic pain, POE clinic evaluation was associated with a higher likelihood for receiving non-opioid multimodal analgesics perioperatively (p = 0.016).

Conclusion

Formal preoperative evaluations are currently underutilized in patients who take buprenorphine, methadone, or naltrexone for chronic pain or SUD. These patients may benefit from POE clinic assessment to optimize perioperative outcomes.

Integrating mechanistic-based and classification-based concepts into perioperative pain management: an educational guide for acute pain physicians

Chronic pain begins with acute pain. Physicians tend to classify pain by duration (acute vs chronic) and mechanism (nociceptive, neuropathic and nociplastic). Although this taxonomy may facilitate diagnosis and documentation, such categories are to some degree arbitrary constructs, with significant overlap in terms of mechanisms and treatments. In clinical practice, there are myriad different definitions for chronic pain and a substantial portion of chronic pain involves mixed phenotypes. Classification of pain based on acuity and mechanisms informs management at all levels and constitutes a critical part of guidelines and treatment for chronic pain care. Yet specialty care is often siloed, with advances in understanding lagging years behind in some areas in which these developments should be at the forefront of clinical practice. For example, in perioperative pain management, enhanced recovery protocols are not standardized and tend to drive treatment without consideration of mechanisms, which in many cases may be incongruent with personalized medicine and mechanism-based treatment. In this educational document, we discuss mechanisms and classification of pain as it pertains to commonly performed surgical procedures. Our goal is to provide a clinical reference for the acute pain physician to facilitate pain management decision-making (both diagnosis and therapy) in the perioperative period.

Shared Decision-Making in Acute Pain Services

PURPOSE OF REVIEW

The implementation of shared decision-making (SDM) in acute pain services (APS) is still in its infancies especially when compared to other medical fields.

RECENT FINDINGS

Emerging evidence fosters the value of SDM in various acute care settings. We provide an overview of general SDM practices and possible advantages of incorporating such concepts in APS, point out barriers to SDM in this setting, present common patient decisions aids developed for APS and discuss opportunities for further development. Especially in the APS setting, patient-centred care is a key component for optimal patient outcome. SDM could be included into everyday clinical practice by using structured approaches such as the "seek, help, assess, reach, evaluate" (SHARE) approach, the 3 "MAking Good decisions In Collaboration"(MAGIC) questions, the "Benefits, Risks, Alternatives and doing Nothing"(BRAN) tool or the "the multifocal approach to sharing in shared decision-making"(MAPPIN'SDM) as guidance for participatory decision-making. Such tools aid in the development of a patient-clinician relationship beyond discharge after immediate relief of acute pain has been accomplished. Research addressing patient decision aids and their impact on patient-reported outcomes regarding shared decision-making, organizational barriers and new developments such as remote shared decision-making is needed to advance participatory decision-making in acute pain services.

Association of preoperative pain catastrophizing with postoperative pain after lower limb trauma surgery

OBJECTIVES

To evaluate an association between preoperative Nepali pain catastrophizing scale (N-PCS) scores and postoperative pain intensity and total opioid consumption.

METHODS

In this prospective cohort study we enrolled 135 patients with an American Society of Anaesthesiologists physical status I or II, aged between 18 and 65 years, and scheduled for surgery for lower-extremity fracture under spinal anaesthesia. Maximum postoperative pain reported during the 24 h was classified into two groups, no-mild pain group (Numeric rating scale [NRS] scores 1-3) and a moderate-severe pain group (NRS 4-10). The Pearson's correlation coefficient was used to compare the association between the baseline N-PCS scores and outcome variables, i.e., the maximum NRS pain score and the total tramadol consumption within the first 24 h after surgery. Logistic regression models were used to identify the predictors for the intensity of postoperative pain.

RESULTS

As four patients violated the protocol, the data of 131 patients were analyzed. Mean N-PCS scores reported by the moderate-severe pain group was 27.39 ± 9.50 compared to 18.64 ± 10 mean N-PCS scores by the no-mild pain group (p < 0.001). Preoperative PCS scores correlated positively with postoperative pain intensity (r = 0.43, [95% CI 0.28-0.56], p < 0.001) and total tramadol consumption (r = 0.36, [95% CI 0.20-0.50], p < 0.001). Preoperative pain catastrophizing was associated with postoperative moderate-severe pain (odds ratio, 1.08 [95% confidence interval, 1.02-1.15], p = 0.006) after adjusting for gender, ethnicity and preoperative anxiety.

CONCLUSION

Patients who reported higher pain catastrophizing preoperatively were at increased risk of experiencing moderate-severe postoperative pain.

The Burden of Opioid-Related Adverse Drug Events on Hospitalized Previously Opioid-Free Surgical Patients

OBJECTIVE

Opioid analgesics are a mainstay for acute pain management, but postoperative opioid administration has risks. We examined the prevalence, risk factors, and consequences of opioid-related adverse drug events (ORADEs) in a previously opioid-free surgical population.

METHODS

A retrospective, observational, cohort study using administrative, billing, clinical, and medication administration data from two hospitals. Data were collected for all adult patients who were opioid-free at admission, underwent surgery between October 1, 2015, and September 30, 2016, and received postoperative opioids. Potential ORADEs were determined based on inpatient billing codes or postoperative administration of naloxone. We determined independent predictors of ORADE development using multivariable logistic regression. We measured adjusted inpatient mortality, hospital costs, length of hospital stay, discharge destination, and readmission within 30 days for patients with and without ORADEs.

RESULTS

Among 13,389 hospitalizations where opioid-free patients had a single qualifying surgery, 12,218 (91%) received postoperative opioids and comprised the study cohort. Of these, we identified 1111 (9.1%) with a potential ORADE. Independent predictors of ORADEs included older age, several markers of disease severity, longer surgeries, and concurrent benzodiazepine use. Opioid-related adverse drug events were strongly associated with the route and duration of opioids administered postoperatively: 18% increased odds per day on intravenous opioids. In analyses adjusted for several covariates, presence of an ORADE was associated with 32% higher costs of hospitalization, 45% longer postoperative length of stay, 36% lower odds of discharge home, and 2.2 times the odds of death.

CONCLUSIONS

We demonstrate a high rate and severe consequences of potential ORADEs in previously opioid-free patients receiving postoperative opioids. Knowledge of risk factors and predictors of ORADEs can help develop targeted interventions to minimize the development of these potentially dangerous and costly events.

Continuous Wound Infiltration with Local Anesthetic Is an Effective and Safe Postoperative Analgesic Strategy: A Meta-Analysis

Introduction

Postoperative pain management is an essential module for perioperative care, especially for enhanced recovery after surgery programs. Continuous wound infiltration (CWI) with local anesthetic may be a promising postoperative analgesic strategy. However, its analgesic efficacy and safety remain debatable.

Methods

Embase and PubMed databases were systematically searched for relevant randomized controlled trials (RCTs). RCTs assessing the analgesic efficacy and safety of CWI with local anesthetic for postoperative analgesia were selected. The outcomes contained pain scores during rest and mobilization, total opioid consumption, time to the first request of rescue analgesia, length of hospital stay, satisfaction with analgesia, time to return of bowel function, postoperative nausea and vomiting, total complication, wound infection, hypotension, and pruritus. The weighted mean difference and risk ratio were used to pool continuous and dichotomous variables, respectively.

Results

A total of 121 RCTs were included. CWI with local anesthetic reduced postoperative pain during rest and mobilization at different time points, increased satisfaction with analgesia, shortened recovery of bowel function, and reduced postoperative nausea and vomiting compared with the placebo group, especially for laparotomy surgery. There were no significant differences in these clinical outcomes compared to epidural and intravenous analgesia. CWI with local anesthetic reduced the total opioid consumption and hypotension risk and did not increase total complications, wound infection, or pruritus. CWI with local anesthetic had a better analgesic efficacy without increased side effects for sternotomy surgery. However, CWI with local anesthetic did not translate into favorable analgesic benefits in laparoscopic surgery.

Conclusion

CWI with local anesthetic is an effective postoperative analgesic strategy with good safety profiles in laparotomy and sternotomy surgery, and thus CWI with local anesthetic may be a promising analgesic option enhancing recovery after surgery programs for these surgeries.

Continuous wound infiltration (CWI) with local anesthetic may be a promising postoperative analgesic strategy, but its effect remains debatable. We performed this meta-analysis based on 121 high-quality articles (RCTs) to evaluate the analgesic efficacy and safety of CWI with local anesthetic. We found that CWI with local anesthetic could reduce postoperative pain, increase satisfaction with analgesia, shorten recovery of bowel function, and reduce postoperative nausea and vomiting, especially for laparotomy surgery. However, CWI with local anesthetic did not show favorable analgesic benefits in laparoscopic surgery.

Chronic pain and substance abuse disorders: Preoperative assessment and optimization strategies

There is an ever-increasing number of opioid users among chronic pain patients and safely managing them can be challenging for surgeons, anesthesiologists, pain experts, and addiction specialists. Healthcare providers must be familiar with phenomena typical of opioid users and abusers, including tolerance, physical dependence, hyperalgesia, and addiction. Insufficient pain management is very common in these patients. Patient-centered preoperative communication is integral to setting realistic expectations for postoperative pain, developing successful nonopioid analgesic regimens, minimizing opioid consumption during the postoperative period, and decreasing the number of opioid pills at the risk of diversion. Preoperative evaluation should identify comorbidities and identify risk factors for substance abuse and withdrawal. Intraoperative and postoperative strategies can ensure safe and effective pain management and minimize the potential for morbidity and mortality in this high-risk patient population.

Physiotherapy management of patients with major chest trauma: Results from a global survey

Aim

Major chest trauma is associated with significant morbidity and mortality. Management of patients with major chest trauma includes pain relief, ventilatory management, surgical fixation and early rehabilitation to improve both short- and long-term outcomes. Physiotherapy is widely considered an integral component of the multidisciplinary trauma team and aims to improve respiratory status and reduce the sequelae associated with immobility and reduced physical function. Despite this there is scarce evidence describing or investigating physiotherapy interventions and how these practices vary worldwide. The aim of this study was to ascertain the current physiotherapy management of patients having sustained major chest trauma and to investigate how such practices varied internationally.

Methods

A purpose designed online survey was administered to a group of experienced physiotherapists who work in the field of trauma.

Results

Response rate was 51% ( n = 49) and respondents represented all five continents. Respondents reported focussing on active coughing ( n = 46, 96%, r = 0.5, p = 0.98), body positioning ( n = 43, 94%, r = 0.7, p = 0.41), deep breathing exercises ( n = 44, 94%, r = 0.8, p = 0.66) and early mobilisation ( n = 47, 98%, r = 1, p = 0.64). Ambulation in hospital was reported to be common ( n = 46, 98%, r = 0.2, p = 0.99) but rehabilitation to address longer term sequelae following hospital discharge was reported to be rare ( n = 4, 8%).

Conclusion

This survey has highlighted those practices used by physiotherapists worldwide which aim to address the complications associated with major chest trauma. Having established global practice, the study provides a platform for future research investigating the efficacy of such interventions in improving both short- and long-term outcomes for patients following major chest injury.

A Dashboard for Monitoring Opioid-Related Adverse Drug Events Following Surgery Using a National Administrative Database

Opioid-related adverse drug events (ORADEs) include a range of complications, from respiratory arrest to ileus and urinary retention. ORADEs correlate to morbidity, mortality, and increased costs. The Centers for Medicare & Medicaid Services database, which represents approximately 35% of hospital discharges. The authors searched for previously published ICD-9 codes that defined ORADEs. A group of surgical diagnosis-related groups (DRGs) were selected. Recurring queries were programmed using these ICD codes and DRGs and used to update an online dashboard. The dashboard presents an estimate of the burden of ORADEs to frontline clinicians and hospital leadership and allows users to compare local data on ORADEs rates to other hospitals. Users are able to refine their search by surgery type or ORADE type. An interface was created, using national administrative claims data, to allow hospitals to access their ORADEs and benchmark local data against national trends.

Comprehensive Acute Pain Management in the Perioperative Surgical Home

The careful coordination of care throughout the perioperative continuum offered by the perioperative surgical home (PSH) is important in the treatment of postoperative pain. Physician anesthesiologists have expertise in acute pain management, pharmacology, and regional and neuraxial anesthetic techniques, making them ideal leaders for managing perioperative analgesia within the PSH. Severe postoperative pain is one of many patient- and surgery-specific factors in the development of chronic postsurgical pain. Delivering adequate perioperative analgesia is important to avoid this development, to decrease perioperative morbidity, and to improve patient satisfaction.

Chronification of Pain: Mechanisms, Current Understanding, and Clinical Implications

PURPOSE OF REVIEW

The development of acute to chronic pain involves distinct pathophysiological changes in the peripheral and central nervous systems. This article reviews the mechanisms, etiologies, and management of chronic pain syndromes with updates from recent findings in the literature.

RECENT FINDINGS

Chronic post-surgical pain (CPSP) is not limited to major surgeries and can develop after smaller procedures such as hernia repairs. While nerve injury has traditionally been thought to be the culprit for CPSP, it is evident that nerve-sparing surgical techniques are not completely preventative. Regional analgesia and agents such as ketamine, gabapentinoids, and COX-2 inhibitors have also been found to decrease the risks of developing chronic pain to varying degrees. Yet, given the correlation of central sensitization with the development of chronic pain, it is reasonable to utilize aggressive multimodal analgesia whenever possible. Development of chronic pain is typically a result of peripheral and central sensitization, with CPSP being one of the most common presentations. Using minimally invasive surgical techniques may reduce the risk of CPSP. Regional anesthetic techniques and preemptive analgesia should also be utilized when appropriate to reduce the intensity and duration of acute post-operative pain, which has been correlated with higher incidences of chronic pain.
