The acute pain service: Present and future role

Using Time-Driven Activity-Based Costing to Model the Costs of Various Process-Improvement Strategies in Acute Pain Management

EXECUTIVE SUMMARY

Pain control for patients undergoing thoracic surgery is essential for their comfort and for improving their ability to function after surgery, but it can significantly increase costs. Here, we demonstrate how time-driven activity-based costing (TDABC) can be used to assess personnel costs and create process-improvement strategies.We used TDABC to evaluate the cost of providing pain control to patients undergoing thoracic surgery and to estimate the impact of specific process improvements on cost. Retrospective healthcare utilization data, with a focus on personnel costs, were used to assess cost across the entire cycle of acute pain medicine delivery for these patients. TDABC was used to identify possible improvements in personnel allocation, workflow changes, and epidural placement location and to model the cost savings of those improvements.We found that the cost of placing epidurals in the preoperative holding room was less than that of placing epidurals in the operating room. Personnel reallocation and workflow changes resulted in mean cost reductions of 14% with epidurals in the holding room and 7% cost reductions with epidurals in the operating room. Most cost savings were due to redeploying anesthesiologists to duties that are more appropriate and reducing their unnecessary duties by 30%. Furthermore, the change in epidural placement location alone in 80% of cases reduced costs by 18%. These changes did not compromise quality of care.TDABC can model personnel costs and process improvements in delivering specific healthcare services and justify further investigation of process improvements.

Improved Outcomes Associated with the Liberal Use of Thoracic Epidural Analgesia in Patients with Rib Fractures

Objective

Each year, more than 150,000 patients with rib fractures are admitted to US trauma centers; as many as 10% die. Effective pain control is critical to survival. One way to manage pain is thoracic epidural analgesia. If this treatment reduces mortality, more frequent use may be indicated.

Methods

We analyzed the patient registry of a level II trauma center. All patients admitted with one or more rib fractures (N = 1,347) were considered. Patients who were not candidates for epidural analgesia (N = 382) were eliminated. Mortality was assessed with binary logistic regressions.

Results

Across the total population, mortality was 6.7%; incidence of pneumonia was 11.1%; mechanical ventilation was required in 23.8% of patients, for an average duration of 10.0 days; average stay in the hospital was 7.7 nights; and 49.7% of patients were admitted to the ICU for an average of 7.2 nights. Epidural analgesia was administered to 18.4% of patients. After matching samples for candidacy, patients who received epidurals were 3.7 years older, fractured 2.6 more ribs, had higher injury severity scores, and were more likely to present with bilateral fractures, flail segments, pulmonary contusions, hemothoraces, and pneumothoraces. Despite greater injury severity, mortality among these patients was lower (0.5%) than those who received alternative care (1.9%). Controlling for age, injury severity, and use of mechanical ventilation, epidural analgesia predicted a 97% reduction in mortality.

Conclusion

Thoracic epidural analgesia associates with reduced mortality in rib fracture patients. Better care of this population is likely to be facilitated by more frequent reliance on this treatment.

Role of WhatsApp-based discussions in improving residents' knowledge of post-operative pain management: a pilot study

Background

To provide a platform for the dissemination of basic knowledge of pain management, a WhatsApp group was created by residents and consultants. Common clinical scenarios, resident queries, and important instructions to be followed by residents with respect to running the Acute Pain Service were discussed in the group. This study evaluates the benefits of this interaction.

Methods

This study was approved by the hospital ethics board and was registered with the Clinical Trial Registry of India. Second- and third-year anesthesia residents were included in a WhatsApp group, along with consultants (board certified anesthesiologists with a special interest in pain). Pain knowledge assessment was performed pre- and post-discussion using a standard 22-point questionnaire. A feedback form, which included self-rated confidence scores (1–10, 10-most confident) and opinions about the 3-month WhatsApp discussion, was collected. Improvements in the documentation in clinical sheets post-discussion were also analyzed.

Results

A total of 38 residents were included in the WhatsApp group. An improvement in the percentage of correct answers from 69.1% (pre-discussion) to 73.6% (post-discussion) was observed (P = 0.031). Improvements in the self-rated residents' confidence levels were also noted (P < 0.05). A total of 37 residents felt that the WhatsApp-based discussion was useful. Documentation of the details of epidural blockade in clinical sheets improved from 30% to 100%.

Conclusions

The WhatsApp discussion improved residents' knowledge and confidence levels, and also resulted in improved documentation of essential details in the clinical notes. This form of education is promising and should be explored in future studies.

Post-operative pain treatment in Denmark from 2000 to 2009: a nationwide sequential survey on organizational aspects

BACKGROUND

In Denmark, the first acute pain service (APS) was introduced in 1993. An important objective became to facilitate implementation of accelerated post-operative rehabilitation programmes (ACC) in selected procedures in abdominal, gynaecological and orthopaedic surgery. Therefore, it is of considerable interest to study the association between the developments of post-operative pain management and the ACC by sequential analyses from 2000 to 2009.

METHODS

In 2000, 2003, 2006 and 2009, a questionnaire was mailed to all Danish anaesthesiology departments. The headings of the questionnaire were demographics of responder departments, resources allocated to pain management methods, quality assessment methods, research activities and implementation of ACC.

RESULTS

The responder rates varied between 80% and 94% (mean 88%) representing a mean number of anaesthetics of 340.000 per year. The number of APSs in the study period varied in university hospitals between 52% and 71% (P = 0.01), regional hospitals between 8% and 40% (P < 0.01), and local hospitals between 0% and 47% (P < 0.01). The prevalences of departments actively engaged in ACC were 40% in 2000, 54% in 2003, 73% in 2006 and 80% in 2009 (P < 0.01).

CONCLUSIONS

The study, spanning nearly a decade, illustrates that following an increase in number of APSs from 2000 to 2006, followed by a significant decline, a steadily increasing number of departments implemented ACC.

Development of acute pain service in an Indian cancer hospital

Postoperative pain relief continues to be a major challenge for all health care professionals caring for such patients in India. Acute pain services are almost nonexistent, even in large private and university hospitals. As per our estimate not more than 10 such services are available. Tata Memorial Hospital is a tertiary care cancer center that started one of the first Acute Pain Services (APS) in India in 2002 to provide safe and effective postoperative pain management. APS guidelines and protocols have since been implemented and patients are monitored by a team of a consultant physician, a nurse, and a medical resident. Audits are done at regular intervals to evaluate the efficacy of service and patient satisfaction. Pain scores declined yet the patient satisfaction has not improved. Postoperative outcome studies are yet to be undertaken. The development and current activities of the APS that can be implemented in a country that does not have sophisticated acute pain management teams are described.
