The minimal important change for the EQ VAS based on the SF-36 health transition item: observations from 25772 spine surgery procedures

Patient-reported outcomes after minimally invasive sacro-iliac joint surgery: a cohort study based on the Swedish Spine Registry

BACKGROUND AND PURPOSE

There is conflicting evidence regarding treatment outcomes after minimally invasive sacroiliac joint fusion for long-lasting severe sacroiliac joint pain. The primary aim of our cohort study was to investigate change in patient-reported outcome measures (PROMs) after minimally invasive sacroiliac joint surgery in daily practice in the Swedish Spine Registry. Secondary aims were to explore the proportion of patients reaching a patient acceptable symptom score (PASS) and the minimal clinically important difference (MCID) for pain scores, physical function, and health-related quality of life outcomes; furthermore, to evaluate self-reported satisfaction, walking distance, and changes in proportions of patients on full sick leave/disability leave and report complications and reoperations.

METHODS

Data from the Swedish Spine Registry was collected for patients with first-time sacroiliac joint fusion, aged 21 to 70 years, with PROMs available preoperatively, at 1 or 2 years after last surgery. PROMs included Oswestry Disability Index (ODI), Numeric Rating Scale (NRS) for low back pain (LBP) and leg pain, and EQ-VAS, in addition to demographic variables. We calculated mean change from pre- to postoperative and the proportion of patients achieving MCID and PASS.

RESULTS

68 patients had available pre- and postoperative data, with a mean age of 45 years (range 25-70) and 59 (87%) were female. At follow-up the mean reduction was 2.3 NRS points (95% confidence interval [CI] 1.6-2.9; P < 0.001) for LBP and 14.8 points (CI 10.6-18.9; P < 0.001) for ODI. EQ-VAS improved by 22 points (CI 15.4-30.3, P < 0.001) at follow-up. Approximately half of the patients achieved MCID and PASS for pain (MCID NRS LBP: 38/65 [59%] and PASS NRS LBP: 32/66 [49%]) and physical function (MCID ODI: 27/67 [40%] and PASS ODI: 24/67 [36%]). The odds for increasing the patient's walking distance to over 1 km at follow-up were 3.5 (CI 1.8-7.0; P < 0.0001), and of getting off full sick leave or full disability leave was 0.57 (CI 0.4-0.8; P = 0.001). In the first 3 months after surgery 3 complications were reported, and in the follow-up period 2 reoperations.

CONCLUSION

We found moderate treatment outcomes after minimally invasive sacroiliac joint fusion when applied in daily practice with moderate pain relief and small improvements in physical function.

Patient-reported Outcome After Surgical Evacuation of Postoperative Spinal Epidural Hematomas at One-year Follow-up

STUDY DESIGN

Retrospective analysis of prospectively collected data from the National Swedish Spine Register (Swespine).

OBJECTIVE

The objective of this study was to evaluate the effects of symptomatic spinal epidural hematoma (SSEH) requiring reoperation on one-year patient-reported outcome measures (PROMs) in a large cohort of patients treated surgically for lumbar spinal stenosis.

SUMMARY OF BACKGROUND DATA

Studies exploring the outcomes of reoperations after SSEH are scarce and often lack validated outcome measures. As SSEH is considered a serious complication, understanding of the outcome after hematoma evacuation is important.

MATERIALS AND METHODS

After retrieving data from 2007 to 2017 from Swespine, we included all patients with lumbar spinal stenosis without concomitant spondylolisthesis who were treated surgically with decompression without fusion. Patients with evacuated SSEH were identified in the registry. Back/leg pain numerical rating scales (NRSs), the Oswestry Disability Index (ODI), and EuroQol Visual Analogue Scale were used for the outcome assessment. PROMs before and one year after decompression surgery were compared between evacuated patients and all other patients. Multivariate linear regression was performed to determine whether hematoma evacuation predicted inferior one-year PROM scores.

RESULTS

A total of 113 patients with an evacuated SSEH were compared with 19527 patients with no evacuation. One-year after decompression surgery, both groups showed significant improvement in all PROMs. When comparing the two groups' one-year improvement, there were no significant differences in any PROM. The proportion of patients achieving the minimum important change was not significantly different for any PROM. Multivariate linear regression found that hematoma evacuation significantly predicted inferior one-year ODI (β=4.35, P =0.043), but it was not a significant predictor of inferior NRS Back (β=0.50, P =0.105), NRS Leg (β=0.41, P =0.221), or EuroQol Visual Analogue Scale (β=-1.97, P =0.470).

CONCLUSIONS

A surgically evacuated SSEH does not affect the outcome in terms of back/leg pain or health-related quality of life. Commonly used PROM surveys may not capture neurological deficits associated with SSEH.

Key Psychosocial Health Outcomes and Association With Resilience Among Patients With Adult Congenital Heart Disease

BACKGROUND

Adult congenital heart disease (ACHD) can negatively impact quality of life (QOL). Strengthening resilience may improve this and other psychosocial outcomes important for living a meaningful life.

OBJECTIVES

The purpose of this study was to describe resilience and key psychosocial health outcomes in ACHD and evaluate the associations between resilience and these outcomes.

METHODS

We conducted a prospective cohort study of outpatients with moderate or complex ACHD between May 2021 and June 2022. Participants completed surveys at baseline and 3 months, evaluating resilience (Connor-Davidson Resilience Scale-10), health-related QOL (EQ5D-3L, linear analog scale), health status (Euroqol visual analog scale), self-competence (Perceived Competence Scale), and psychological symptom burden (Hospital Anxiety and Depression Scale) and distress (Kessler-6).

RESULTS

The mean participant age (N = 138) was 41 ± 14 years, 51% were female, and 83% self-identified as non-Hispanic White. ACHD was moderate for 75%; 57% were physiologic class B. Mean baseline resilience score (Connor-Davidson Resilience Scale-10) was 29.20 ± 7.54. Participants had relatively good health-related QOL, health status, and self-competence, and low psychological symptom burden and distress. Higher baseline resilience was associated with better values of all outcomes at 3 months (eg, 1 point higher resilience was associated with 0.92 higher linear analog scale; 95% CI: 0.52-1.32) with or without adjustment for demographics. After further adjusting for the baseline psychosocial measure, only the association between resilience and QOL measures at 3 months remained statistically significant.

CONCLUSIONS

Resilience is positively associated with health-related QOL for outpatients with moderate or complex ACHD, though relationships are small in magnitude. Study findings can guide the application of resilience-building interventions to the ACHD population.

Long-Term (>24 Months) Duration of Symptoms Negatively Impacts Patient-Reported Outcomes Following Anterior Cervical Discectomy and Fusion for Cervical Radiculopathy

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To investigate the impact of long symptom duration (>24 mo) on patient self-reported outcomes for pain, function, and quality of life following anterior cervical discectomy and fusion (ACDF) for cervical radiculopathy.

SUMMARY OF BACKGROUND DATA

ACDF is an effective treatment to relieve the symptoms of cervical radiculopathy. However, there is no consensus on whether prolonged preoperative length of symptoms negatively impacts postoperative outcomes.

METHODS

This study included consecutive patients who underwent ACDF for cervical radiculopathy from May 1, 2012 to Dec 1, 2019 by a single surgeon. Patients were stratified by short (<24 mo) and long (>24 mo) duration of symptoms. Outcomes including visual analog scale (VAS) neck and arm, neck disability index (NDI), EuroQol-5D (EQ-5D), and overall state of health (EQ-VAS) were compared between cohort both for absolute values and percentage of patients achieving minimal clinically important difference.

RESULTS

A total of 111 consecutive patients were included in our study, including 59 patients in the short symptom duration group and 52 patients in the long symptom duration group. The mean age of the patients was 51.4±9.4 and 41 (36.9%) were female. The baseline VAS neck and arm, NDI, EQ-5D, and EQ-VAS were similar between groups. Patients in both long and short symptom duration groups had clinical improvement following surgery. However, patients with short symptom duration had better VAS Neck and EQ-5D outcomes, and were more likely to meet minimal clinically important difference for NDI, EQ-5D, or any outcome. Multivariate analysis confirmed symptom duration <24 months as an independent predictor for better patient-reported outcomes.

CONCLUSION

We appreciated better clinical outcomes in patients with shorter symptom duration who received ACDF for cervical radiculopathy. On the basis of this data, we advocate for prompt treatment of cervical radiculopathy to avoid the potential for long-term impairment.

How do survivors after out-of-hospital cardiac arrest perceive their health compared to the norm population? A nationwide registry study from Norway

Introduction

Self-perceived health status data is usually collected using patient-reported outcome measures. Information from the patients' perspective is one of the important components in planning person-centred care. The study aimed to compare EQ-5D-5L in survivors after out-of-hospital cardiac arrest (OHCA) with data for Norwegian population controls. Secondary aim included comparing characteristics of respondents and non-respondents from the OHCA population.

Methods

In this cross-sectional survey, 714 OHCA survivors received an electronic EQ-5D-5L questionnaire 3-6 months following OHCA. EQ-5D-5L assesses for five dimensions of health (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) with five-point descriptive scales and overall health on a visual analogue scale from 0 (worst) to 100 (best) (EQ VAS). Results are used to calculate the EQ index ranging from -0.59 (worst) to 1 (best). Patient responses were matched for age and sex with existing data from controls, collected through a postal survey (response rate 26%), and compared with Chi-square tests or t-tests as appropriate.

Results

Of 784 OHCA survivors, 714 received the EQ-5D-5L, and 445 (62%) responded. Respondents had higher rates of shockable first rhythm and better cerebral performance category scores than the non-respondents. OHCA survivors reported poorer health compared to controls as assessed by EQ-5D-5L dimensions, the EQ index (0.76 ± 0.24 vs 0.82 ± 0.18), and EQ VAS (69 ± 21 vs 79 ± 17), except for the pain/discomfort dimension.

Conclusions

Norwegian OHCA survivors reported poorer health than the general population as assessed by the EQ-5D-5L. PROMs use in this population can be used to inform follow-up and health care delivery.

Use of EQ-5D-5L for Assessing Patient-Reported Outcomes in a National Register for Specialized Rehabilitation

OBJECTIVE

To compare problems reported on EQ-5D-5L dimensions, index, and EQ visual analog scale (VAS) scores in patients receiving specialized rehabilitation in Norway with general population norms.

DESIGN

Multicenter observational study.

SETTING

Five specialist rehabilitation facilities participating in a national rehabilitation register between March 11, 2020, and April 20, 2022.

PARTICIPANTS

1167 inpatients admitted (N=1167), with a mean age of 56.1 (range, 18-91) years; 43% were female.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

EQ-5D-5L dimension, index, and EQ VAS scores.

RESULTS

At admission, mean±SD EQ-5D-5L index scores were 0.48 (0.31) compared to 0.82 (0.19) for general population norms. EQ VAS scores were 51.29 (20.74) compared to 79.46 (17.53) for population norms. Together with those for the 5 dimensions, these differences were all statistically significant (P<.01). Compared to population norms, patients undergoing rehabilitation had more health states as assessed by the 5 dimensions (550 vs 156) and EQ VAS (98 vs 49). As hypothesized, EQ-5D-5L scores were associated with number of diagnoses, admission to/from secondary care, and help with completion. At discharge there were statistically significant improvements in all EQ-5D-5L scores that compare favorably with available estimates for minimal important differences.

CONCLUSIONS

The large deviations in scores at admission and score changes at discharge lend support to EQ-5D-5L application in national quality measurement. Evidence for construct validity was found through associations with number of secondary diagnoses and help with completion.
