Return to work and productivity loss after surgery: A health economic evaluation

Robotic colorectal resections are associated with less postoperative pain, decreased opioid use, and earlier return to work as compared to the laparoscopic approach

While robotic and laparoscopic surgeries are both minimally invasive in nature, they are intrinsically different approaches and it is critical to understand outcome differences between the two. Studies evaluating pain outcomes and opioid requirement differences between the robotic and laparoscopic colorectal resections are conflicting and often underpowered. In this retrospective, cohort study, we compare postoperative opioid requirements, reported as morphine milligram equivalents (MME), postoperative average and highest pain scores across postoperative days (POD) 0-5, and return to work in patients who underwent robotic versus laparoscopic colorectal resections. The sample size was selected based on power calculations. Daily pain scores and MME were used as outcomes in linear mixed effect models with unstructured covariance between time points. Propensity score weighting was used to adjust for imbalances. Patients in the robotic group required significantly less opioids as measured by MME on all postoperative days (p = 0.004), as well as lower average and highest daily pain scores for POD 0-5 (p = 0.02, and p = 0.006, respectively). In a linear mixed-effects model, robotic resections were associated with a decrease in average pain scores by 0.36 over time (p = 0.03) and 35 fewer MME requirements than the laparoscopic group (p = 0.0004). Patients in the robotic arm had earlier return to work (2.1 vs 3.8 days, p = 0.036). The robotic approach to colorectal resections is associated with significantly less postoperative pain, decreased opioid requirements, and earlier return to work when compared to laparoscopy, suggesting that the robotic platform provides important clinical advantages over the laparoscopic approach.

Clinical and socioeconomic factors predicting return-to-work times after cholecystectomy

BACKGROUND

Cholecystectomy, a type of surgery commonly performed globally, has possible mutual effects on the socioeconomic conditions of different countries due to various postoperative recovery times.

AIMS

This study evaluated the medical and socioeconomic factors affecting delayed return-to-work (RTW) time after elective cholecystectomy.

METHODS

This retrospective study analysed patients who underwent elective cholecystectomy for benign gallbladder diseases from January 2022 to April 2023. The patients' medical and socioeconomic data were collected to investigate the clinical and socioeconomic factors correlated with RTW time of >30 days after surgery.

RESULTS

This study included 180 consecutive patients. Significant correlations were found between delayed RTW time (>30 days) and age (odds ratio [OR]: 1.059, 95% confidence interval [CI] 1.008-1.113, P = 0.024), lack of medical insurance (OR: 2.935, 95% CI 1.189-7.249, P = 0.02) and high-intensity labour jobs (OR: 3.649, 95% CI 1.495-8.909, P = 0.004). Patients without medical insurance (26.6 versus 18.9 days) and those with high-intensity labour jobs (23.9 versus 18.8 days) had a higher mean RTW time than those with insurance and a less-intense labour job (P < 0.001).

CONCLUSIONS

After cholecystectomy, older age, lack of medical insurance and high-intensity labour job were correlated with a delayed RTW time. Informing patients about their expected RTW time after surgery can help reduce costs.

Breast Conservation Project: Clinical Outcomes of Extreme Oncoplastic Breast-Conserving Therapy Versus Mastectomy for Large and Multiple Lesions

INTRODUCTION

Patients with multiple or large malignant breast lesions are classically considered mastectomy candidates, but extreme oncoplastic breast-conservation surgery (eOBCS) has become an alternative approach. There is a paucity of outcomes data comparing eOBCS with mastectomy.

METHODS

We reviewed our prospectively maintained, single-institution database. We included patients with non-metastatic breast cancer with multiple ipsilateral or single large (≥ 5 cm) malignant breast lesions identified preoperatively who underwent either eOBCS or mastectomy. Patient demographics, clinicopathologic features, and surgical, oncologic, and cosmetic outcomes were evaluated.

RESULTS

Seventy-six (88%) patients underwent eOBCS and 10 (12%) underwent mastectomy. Median follow-up was 24.8 months. Mastectomy patients had larger lesions than eOBCS patients (median 70 mm vs. 32.5 mm; p = 0.06). Six (60%) index mastectomy patients underwent at least one additional surgery. For eOBCS patients, 34 (44%) required re-excision, 7 of whom underwent more than one subsequent surgery to obtain negative margins, and 6 (7.9%) ultimately underwent mastectomy. For patients undergoing additional surgery (n = 40), median time between index and final operation was 315 days for mastectomy versus 21 days for eOBCS patients (p < 0.001). Mastectomy patients more frequently experienced complications (p = 0.001) and underwent cosmetic revision (p < 0.001). There was no difference in cosmetic scores, and eOBCS patients reported less pain (p = 0.009). There were two local and three distant recurrences in the eOBCS cohort and one distant recurrence in the mastectomy group.

CONCLUSION

Breast conservation was attainable in over 90% of eOBCS patients. Increased postoperative complications and discomfort and longer duration of surgical treatment in mastectomy patients without oncologic superiority should drive informed patient discussions.

Impact of Postoperative COVID-19 Infection Status on Outcomes in Elective Primary Total Joint Arthroplasty

BACKGROUND

Although Coronavirus disease 2019 (COVID-19) infection causes major morbidity and mortality, it is unclear what the impact of postoperative COVID-19 infection is on 30-day outcomes after total joint arthroplasty (TJA).

METHODS

There were 2,340 patients who underwent TJA in 2021, identified using the National Surgical Quality Improvement Program database, with 925 total hip arthroplasty (THA) patients (39.5%) and 1,415 total knee arthroplasty (TKA) patients (60.5%), overall. Propensity score matching was implemented using patient demographics and preoperative medical conditions to compare outcomes for postoperative COVID-19-positive and COVID-19-negative patients who underwent TKA or THA.

RESULTS

Postoperative COVID-19-positive THA patients were found to have a significantly increased risk of pneumonia (odds ratio [OR] 42.57), sepsis (OR 12.77), readmission (OR 12.06), non-home discharge (OR 3.78), and longer length of stay (hazard ratio 1.62). Postoperative COVID-19-positive TKA patients had an increased risk of 30-day mortality (OR 14.17), superficial infection (OR 3.17), pneumonia (OR 34.68), unplanned intubation (OR 18.31), ventilator use for more than 48 hours (OR 18.31), pulmonary embolism (OR 11.98), urinary tract infection (OR 5.16), myocardial infarction (OR 16.02), deep vein thrombosis (OR 4.69), non-home discharge (OR 1.79), reoperation (OR 3.17), readmission (OR 9.61), and longer length of stay (hazard ratio 1.49).

CONCLUSIONS

Patients who contracted COVID-19 within 30 days after TJA were at increased risk of mortalities, medical complications, readmissions, reoperations, and non-home discharges. It is important for orthopedic surgeons to understand these adverse outcomes to better counsel patients and mitigate these risks, particularly in higher risk populations.

Effectiveness of the Coordinated Return to Work model after orthopaedic surgery for lumbar discectomy and hip and knee arthroplasty: a register-based study

OBJECTIVES

This study examined the effectiveness of an individualised Coordinated Return to Work (CRtW) model on the length of the return to work (RTW) period compared with a standard prescription of 2-3 months RTW during recovery after lumbar discectomy and hip and knee arthroplasty among Finnish working-age population.

METHODS

Cohorts on patients aged 18-65 years old with lumbar discectomy or hip or knee arthroplasty were extracted from the electronic health records of eight Finnish hospital districts in 2015-2021 and compiled with retirement and sickness benefits. The overall effect of the CRtW model on the average RTW period was calculated as a weighted average of area-specific mean differences in RTW periods between 1 year before and 1 year after the implementation. Longer-term effects of the model were examined with an interrupted time series design estimated with a segmented regression model.

RESULTS

During the first year of the CRtW model, the average RTW period shortened by 9.1 days (95% CI 4.1 to 14.1) for hip arthroplasty and 14.4 days (95% CI 7.5 to 21.3) for knee arthroplasty. The observed differences were sustained over longer follow-up times. For lumbar discectomy, the first-year decrease was not statistically significant, but the average RTW had shortened by 36.2 days (95% CI 33.8 to 38.5) after 4.5 years.

CONCLUSIONS

The CRtW model shortened average RTW periods among working-age people during the recovery period. Further research with larger samples and longer follow-up times is needed to ensure the effectiveness of the model as a part of the Finnish healthcare system.

Improvement in functional outcome 1 year after nonsurgical multidisciplinary treatment for chronic pain after total knee arthroplasty: A prospective cohort study

PURPOSE

The purpose of this study was to evaluate a multidisciplinary intervention developed for patients with debilitating chronic pain after total knee arthroplasty (TKA) unresponsive to existing treatment options.

METHODS

A treatment-based prospective cohort study was caried out in 30 TKA patients with debilitating chronic pain at least 1 year after TKA. The treatment was a multidisciplinary intervention. Main inclusion criteria: no indication for surgery. Primary outcome was function measured by KOOS-PS, OKS, OKS-APQ and WORQ. Secondary outcome measures were pain, fear of movement, self-efficacy, quality of life (QoL), health care and pain medication use, work rehabilitation and patient satisfaction. The assessments took place pre- and directly posttreatment, at 1, 3 and 12 months follow-up. The clinical relevance was assessed by predefined minimal important clinical change (MCIC).

RESULTS

At baseline patients were on average 64.7 (±7.9) years old, 67% were female, and they had knee pain for 42 (10-360) months. The results at 12-month follow-up: first, a significant improvement was shown in function, pain, fear of movement, self-efficacy and QoL. Second, in 38.5%-69.2% of patients clinical relevant improvement was shown for functional outcome, 31% for pain, and 50% for self-efficacy. Third, 42% of patients reported 'no healthcare use in the past three months'.

CONCLUSION

One year after a multidisciplinary treatment a clinically relevant improvement was shown in terms of function, pain, self-efficacy and QoL. It seems to be a promising treatment option in this difficult-to-treat patient group with debilitating chronic pain after TKA. Future research should examine the effect of the treatment in a larger study population, considering a control group, and focusing on the working population and evaluating cost-efficacy.

The long-term impacts of opioid use before and after joint arthroplasty: matched cohort analysis of New Zealand linked register data

BACKGROUND

Opioids are commonly used both before and after total joint arthroplasty (TJA).

OBJECTIVE

The objective of this study was to estimate the long-term effects of pre- and perioperative opioid use in patients undergoing TJA.

METHODS

We used linked population datasets to identify all (n =18,666) patients who had a publicly funded TJA in New Zealand between 2011 and 2013. We used propensity score matching to match individuals who used opioids either before surgery, during hospital stay, or immediately post-discharge with individuals who did not based on a comprehensive set of covariates. Regression analysis was used to estimate the effect of opioid use on health and socio-economic outcomes over 5 years.

RESULTS

Opioid use in the 3 months prior to surgery was associated with significant increases in healthcare utilization and costs (number of hospitalizations 6%, days spent in hospital 14.4%, opioid scripts dispensed 181%, and total healthcare costs 11%). Also increased were the rate of receiving social benefits (2 percentage points) and the rates of opioid overdose (0.5 percentage points) and mortality (3 percentage points). Opioid use during hospital stay or post-discharge was associated with increased long-term opioid use, but there was little evidence of other adverse effects.

CONCLUSIONS

Opioid use before TJA is associated with significant negative health and economic consequences and should be limited. This has implications for opioid prescribing in primary care. There is little evidence that peri- or post-operative opioid use is associated with significant long-term detriments.

Severity of Prior Coronavirus Disease 2019 is Associated With Postoperative Outcomes After Major Inpatient Surgery

OBJECTIVE

To determine how the severity of prior history (Hx) of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection influences postoperative outcomes after major elective inpatient surgery.

BACKGROUND

Surgical guidelines instituted early in the coronavirus disease 2019 (COVID-19) pandemic recommended a delay in surgery of up to 8 weeks after an acute SARS-CoV-2 infection. This was based on the observation of elevated surgical risk after recovery from COVID-19 early in the pandemic. As the pandemic shifts to an endemic phase, it is unclear whether this association remains, especially for those recovering from asymptomatic or mildly symptomatic COVID-19.

METHODS

Utilizing the National COVID Cohort Collaborative, we assessed postoperative outcomes for adults with and without a Hx of COVID-19 who underwent major elective inpatient surgery between January 2020 and February 2023. COVID-19 severity and time from infection to surgery were each used as independent variables in multivariable logistic regression models.

RESULTS

This study included 387,030 patients, of whom 37,354 (9.7%) were diagnosed with preoperative COVID-19. Hx of COVID-19 was found to be an independent risk factor for adverse postoperative outcomes even after a 12-week delay for patients with moderate and severe SARS-CoV-2 infection. Patients with mild COVID-19 did not have an increased risk of adverse postoperative outcomes at any time point. Vaccination decreased the odds of respiratory failure.

CONCLUSIONS

Impact of COVID-19 on postoperative outcomes is dependent on the severity of illness, with only moderate and severe disease leading to a higher risk of adverse outcomes. Existing perioperative policies should be updated to include consideration of COVID-19 disease severity and vaccination status.

Does Consulting an Occupational Medicine Specialist Decrease Time to Return to Work Among Total Knee Arthroplasty Patients? A 12-Month Prospective Multicenter Cohort Study

PURPOSE

The aim of this study is to investigate whether total knee arthroplasty (TKA) patients who consulted an occupational medicine specialist (OMS) within 3 months after surgery, return to work (RTW) earlier than patients who did not consult an OMS.

METHODS

A multi-center prospective cohort study was performed among working TKA patients, aged 18 to 65 years and intending to RTW. Time to RTW was analyzed using Kaplan Meier and Mann Whitney U (MWU), and multiple linear regression analysis was used to adjust for effect modification and confounding.

RESULTS

One hundred and eighty-two (182) patients were included with a median age of 59 years [IQR 54-62], including 95 women (52%). Patients who consulted an OMS were less often self-employed but did not differ on other patient and work-related characteristics. TKA patients who consulted an OMS returned to work later than those who did not (median 78 versus 62 days, MWU p < 0.01). The effect of consulting an OMS on time to RTW was modified by patients' expectations in linear regression analysis (p = 0.05). A median decrease in time of 24 days was found in TKA patients with preoperative high expectations not consulting an OMS (p = 0.03), not in patients with low expectations.

CONCLUSIONS

Consulting an OMS within 3 months after surgery did not result in a decrease in time to RTW in TKA patients. TKA patients with high expectations did RTW earlier without consulting an OMS. Intervention studies on how OMSs can positively influence a timely RTW, incorporating patients' preoperative expectations, are needed.

Cost Analysis of Intramedullary Screw versus Plate Osteosynthesis for Phalangeal and Metacarpal Fractures: An Observational Study

Background: To compare the observed healthcare and societal costs of intramedullary screw (IMS) and plate fixation of extra-articular metacarpal and phalangeal fractures in a contemporary Australian context. Methods: A retrospective analysis, based on previously published data, was performed utilising information from Australian public and private hospitals, the Medicare Benefits Schedule (MBS) and the Australian Bureau of Statistics. Results: Plate fixation demonstrated longer surgical lengths (32 minutes, compared to 25 minutes), greater hardware costs (AUD 1,088 vs. AUD 355), more extended follow-up requirements (6.3 months, compared to 5 months) and higher rates of subsequent hardware removal (24% compared to 4.6%), resulting in an increased healthcare expenditure of AUD 1,519.41 in the public system, and AUD 1,698.59 in the private sector. Wage losses were estimated at AUD 15,515.78 when the fracture cohort is fixed by a plate, and AUD 13,542.43 when using an IMS - a differential of AUD 1,973.35. Conclusions: There is a substantial saving to both the health system and the patient when using IMS fixation over dorsal plating for the fixation of extra-articular metacarpal and phalangeal fractures. Level of Evidence: Level III (Cost Utility).

Factors contributing to the utilization of robotic colorectal surgery: a systematic review and meta-analysis

BACKGROUND

Some studies have suggested disparities in access to robotic colorectal surgery, however, it is unclear which factors are most meaningful in the determination of approach relative to laparoscopic or open surgery. This study aimed to identify the most influential factors contributing to robotic colorectal surgery utilization.

METHODS

We conducted a systematic review and random-effects meta-analysis of published studies that compared the utilization of robotic colorectal surgery versus laparoscopic or open surgery. Eligible studies were identified through PubMed, EMBASE, CINAHL, Cochrane CENTRAL, PsycINFO, and ProQuest Dissertations in September 2021.

RESULTS

Twenty-nine studies were included in the analysis. Patients were less likely to undergo robotic versus laparoscopic surgery if they were female (OR = 0.91, 0.84-0.98), older (OR = 1.61, 1.38-1.88), had Medicare (OR = 0.84, 0.71-0.99), or had comorbidities (OR = 0.83, 0.77-0.91). Non-academic hospitals had lower odds of conducting robotic versus laparoscopic surgery (OR = 0.73, 0.62-0.86). Additional disparities were observed when comparing robotic with open surgery for patients who were Black (OR = 0.78, 0.71-0.86), had lower income (OR = 0.67, 0.62-0.74), had Medicaid (OR = 0.58, 0.43-0.80), or were uninsured (OR = 0.29, 0.21-0.39).

CONCLUSION

When determining who undergoes robotic surgery, consideration of factors such as age and comorbid conditions may be clinically justified, while other factors seem less justifiable. Black patients and the underinsured were less likely to undergo robotic surgery. This study identifies nonclinical disparities in access to robotics that should be addressed to provide more equitable access to innovations in colorectal surgery.
