Defining a standard set of patient-centered outcomes for men with localized prostate cancer

Core outcomes for the evaluation of new healthcare programmes - a modified Delphi study

BACKGROUND

New healthcare programmes that focus on the encounter between patients and healthcare services, such as those advocated for in different forms on "centredness", are being pushed to the forefront of the healthcare agenda to, amongst other goals, combat rising costs. However, lack of consensus regarding which outcomes should be evaluated to cover the needs of all stakeholders creates barriers to prioritising between competing alternatives. The aim of this research was to develop a core outcome set (COS) for the evaluation of new healthcare programmes adopting centredness within the encounter between patients and healthcare services.

METHODS

A COS was developed according to the Core Outcome Measures in Effectiveness Trials guidelines, using the DelphiManager online platform. A list of outcomes was collected from literature, stakeholder group representatives and patient partners. The outcomes underwent a two-round modified Delphi method with representative groups including managerial decision-makers, researchers, health workers, and patients/patient representatives. Outcomes scored 7-9 (critical) by 70% or more participants and 1-3 (limited importance) by no more than 15% were deemed to have reached consensus at the conclusion of round two. The COS was finalised during the consensus meeting, conducted with patient partners and written input from stakeholder representatives.

RESULTS

An initial list of 65 outcomes from literature were refined to 51 items at the end of the pilot phase. At the completion of round two, eight outcomes had been scored critical by all stakeholder groups. A further 28 outcomes scored critical by at least one stakeholder group were included during the consensus meeting. The COS included 36 outcomes divided into six categories, i.e., general health, capabilities and support systems, care processes, organisational, economics, and eHealth.

CONCLUSION

This was a first attempt at developing a COS for new healthcare programmes that adopt centredness within the encounter between patients and healthcare services, resulting in 36 outcomes divided into six categories judged critical by many of the included stakeholders. While providing a first step towards understanding stakeholder needs for implementing or participating in these healthcare programmes, variation between groups highlights the difficulties in allocating resources and attributing value to healthcare programmes practicing centredness.

Evaluating an electronic patient-reported outcome monitoring system in patients with prostate cancer in routine clinical care: a prospective observational study

PURPOSE

This study evaluated the feasibility, acceptability, and clinical utility of an electronic patient-reported outcome (ePRO) system for patients undergoing radiation therapy (RT) for prostate cancer in routine clinical practice.

METHODS

A prospective observational study was conducted at the Medical University of Innsbruck among patients receiving RT for primary or recurrent prostate cancer. The ePRO system was designed to capture patient-reported symptoms and health-related quality of life throughout treatment and follow-up, aiming to standardize symptom monitoring and improve continuity of care. Patients completed questionnaires at baseline, during treatment, and in follow-up with feasibility defined as ≥ 75% of patients completing at least 75% of scheduled assessments. Patients' acceptability was evaluated at baseline and at treatment end using self-developed questionnaires. Healthcare professionals' (HCPs) perception of clinical utility of the system was measured with a self-developed questionnaire.

RESULTS

Forty patients participated in the study with a median age of 71 years. The ePRO system was feasible, with an average completion rate of 87%, exceeding the feasibility threshold. Patient acceptability was high, with 98% (39/40) expressing willingness to use it regularly. HCPs' feedback was also positive, with all HCPs (100%, 8/8) reporting usefulness of the system in clinical care and 83% reporting that the system helped them in the clinical assessment of their patients.

CONCLUSION

The ePRO monitoring system was feasible and well-accepted among both patients and HCPs, demonstrating potential for continued use in routine clinical care. Further efforts are needed to optimize clinical integration and address barriers to ensure equitable access.

Patient-reported outcome measures (PROMs) used to assess sexual functioning in prostate cancer patients: a systematic review of psychometric properties

BACKGROUND

Prostate cancer (PCa) significantly impacts patients' sexual functioning and quality of life. Patient-reported outcome measures (PROMs) are essential for accurately assessing these issues, yet a comprehensive evaluation of their psychometric properties in PCa patients is lacking.

AIMS

This systematic review aimed to provide a comprehensive evaluation of all generic and specific PROMs used to assess sexual functioning in PCa patients and make recommendations the application of PROMs in this patient group.

METHODS

Six electronic databases were searched from up to May 5, 2024. Studies reporting the development and/or validation of PROMs for PCa patients or generic instruments administered to this population were included. The COSMIN risk of bias checklist was adopted to assess the methodological quality and psychometric properties of included PROMs. Psychometric properties of the PROM in each included study were rated against the criteria for good measurement properties based on the COSMIN guideline.

OUTCOMES

The main outcome was to identify the appropriate PROM that can be adopted and used for assessing sexual functioning in PCa patients in clinical setting.

RESULTS

A total of 10 PROMs were identified across 32 studies, primarily focusing on localized PCa patients after radical prostatectomy. The Expanded Prostate Cancer Index Composite (EPIC-26) was the most frequently evaluated and widely used PROM in clinical practice. EPIC-26 (Spanish, Italian, Chinese versions) and UCLA Prostate Cancer Index (UCLA-PCI) demonstrated better psychometric properties compared to other scales. However, no PROM met all COSMIN standards.

CLINICAL IMPLICATIONS

In a clinical setting, it is crucial to utilize well-validated PROMs with good psychometric properties to effectively identify patients with PCa experiencing sexual difficulties who may require additional support.

STRENGTHS AND LIMITATIONS

We applied strict inclusion criteria related to study design and study population, ensuring the assumption of transitivity and the consistency of the analysis.

CONCLUSION

Although EPIC-26 is a shortened version with strong psychometric properties, it may still be too lengthy for patients with significant health issues. Furthermore, the included PROMs do not address issues related to partner relationships, or the psychological impact of sexual dysfunction in sufficient detail. Future research should aim to develop and validate new PROMs that fill these gaps. These tools should be both psychometrically robust and practical for routine use, enabling real-time monitoring and improved care delivery.

A controlled study of use and effectiveness of phosphodiesterase-5 inhibitors in long-term survivors after curative radiotherapy for prostate cancer (PCa)

BACKGROUND AND PURPOSE

We lack population-based data on the use and effectiveness of phosphodiesterase- 5inhibitors (PDE-5Is) in post-radiotherapy long-term prostate cancer survivors (PCaSs). In this cross-sectional survey performed 9 years after curative radiotherapy we explored PDE-5I use and the drugs'effectiveness in 1,092 nine-year PCaSs responding to the sexual items of EPIC-26. The findings from PCaSs were compared to those from 2,847 age-similar men from the general population (Norms).

RESULTS

13 % of the PCaSs and 9 % of the Norms were Current Users of PDE-5Ies, High sexual interest and, restricted to PCaSs, age below 70 years significantly increased the use of PDE-Is. In PCaSs and Norms, who used PDE-5Is the levels of the six sexual items of EPIC-26 and of the Sexual Domain Summary Score (DSS) were similar. The corresponding differences were large in Never Users of PDE-5Ies. High sexual interest in PCaSs, and use of PDE-5Is were significantly and positively associated with an acceptable level of the sexual domain in EPIC-26 (Score > 40), whereas the association was negative for age > 70 years, reduced health and obesity, CONCLUSION: At least 1 of 10 long-term post-radiotherapy PCaSs experience "some help" of their erectile dysfunction by use of PDE-5Is. These patients are identified by high sexual interest, age < 70 years and good health During long-term follow-up of PCaSs clinicians are challenged early to identify these, often relatively young men, based on their high sexual interest.

An Overview of Patient-reported Outcomes for Men with Prostate Cancer: Results from the PIONEER Consortium

Background and objective

Patient-reported outcome measures (PROMs) are increasingly being used to capture the patients' perspective of their functional status and quality of life (QoL). Big data can help us better understand patient-reported outcomes (PROs). Using prospectively collected data from the Prostate Cancer Diagnosis and Treatment Enhancement Through the Power of Big Data in Europe (PIONEER) consortium, we aimed to describe the functional status and QoL in men with prostate cancer (PCa) treated with active surveillance (AS), radical prostatectomy (RP), and radiotherapy (RT), and to demonstrate the applicability of PROM data on a large scale and at a European level.

Methods

We identified data sources that collected QoL data using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-PR25, or Expanded Prostate Cancer Index Composite (EPIC)-26/50 questionnaires. Aggregated summary scores for urinary, bowel, and sexual dysfunction, global health status, and QoL were shared for each data source.

Key findings and limitations

We identified eight data sources originating from various settings: routine hospital data, embedded research PRO collection, survey data collected by a patient organization, multi-institutional prospective cohort study, and registry data. PRO data were available for 709 men on AS, 20 508 on RP, and 3417 on RT, with a median time between diagnosis and PROM assessment ranging from 1 to 8.7 yr. Most men were diagnosed with Gleason ≤7 disease, and T1 or T2 PCa. We observed that sexual dysfunction was the most affected PRO and found large differences between data sources.

Conclusions and clinical implications

Our results support the feasibility of PRO assessment using big data in Europe. Implementation of PROMs in clinical practice and the use of standardized methods could improve value-based health care provision.

Patient summary

In this study, we combined several data sources that reported urinary, bowel, and sexual dysfunction, global health status, and quality of life. We identified eight data sources and show that sexual function is the most affected domain after treatment.

Irish Prostate Cancer Outcomes Research (IPCOR) registry: cohort profile

PURPOSE

To describe the Irish Prostate Cancer Outcomes Research (IPCOR) registry. The cohort was collected to inform and improve the prostate cancer journey of men in Ireland.

PARTICIPANTS

Established in 2015, IPCOR was a unique large-scale prospective cohort study registering men with prostate cancer in Ireland. From 2016 to 2020, IPCOR collected data on 6816 men who were newly diagnosed with prostate cancer across 16 hospitals, both public and private. A comprehensive clinical dataset was collected, capturing detailed information on men's diagnosis, treatments and follow-up. In addition, a subset of 873 men completed patient-reported outcome measures.

FINDINGS TO DATE

The IPCOR study has revealed several key insights into prostate cancer diagnosis and treatment in Ireland. The data indicate a high rate of diagnosis through opportunistic Prostate-Specific Antigen screening, with many cases identified at an early stage.

FUTURE PLANS

IPCOR invites collaboration from the global cancer research community to use this resource to advance prostate cancer research and improve patient outcomes worldwide. IPCOR aims to continue updating long-term survival follow-up data for this cohort. It also plans to continue its collaborative approach with patients, engaging with the Lived Experience Advisory Panel in interpreting results emerging from this dataset. Moving forward, IPCOR is planning its next phase of the project, IPCOR 2.0. This will be a prospective, longitudinal, multi-centre clinical quality registry and biorepository.

Patient-reported Outcome Measures and Experience Measures After Active Surveillance Versus Radiation Therapy Versus Radical Prostatectomy for Prostate Cancer: A Systematic Review of Prospective Comparative Studies

BACKGROUND AND OBJECTIVE

Current management options for localized prostate cancer (PCa) include radical prostatectomy (RP), radiotherapy (RT), and active surveillance (AS). Despite comparable oncological outcomes, there is still lack of evidence on their comparative effectiveness in terms of patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs). We conducted a systematic review of studies comparing PROMs and PREMs after all recommended management options for localized PCa (RP, RT, AS).

METHODS

A literature search was performed in the MEDLINE, EMBASE, and Cochrane CENTRAL databases in accordance with recommendations from the European Association of Urology Guidelines Office and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. All prospective clinical trials reporting PROMs and/or PREMs for comparisons of RP versus RT versus AS were included. A narrative synthesis was used to summarize the review findings. No quantitative synthesis was performed because of the heterogeneity and limitations of the studies available.

KEY FINDINGS AND LIMITATIONS

Our findings reveal that RP mostly affects urinary continence and sexual function, with better results for voiding symptoms in comparison to other treatments. RT was associated with greater impairment of bowel function and voiding symptoms. None of the treatments had a significant impact on mental or physical quality of life. Only a few studies reported PREMs, with a high rate of decision regret for all modalities (up to 23%).

CONCLUSIONS AND CLINICAL IMPLICATIONS

All recommended treatments for localized PCa have an impact on PROMs and PREMs, but for different domains and with differing severity. We found significant heterogeneity in PROM collection, so standardization in real-world practice and clinical trials is warranted. Only a few studies have reported PREMs, highlighting an unmet need that should be explored in future studies.

PATIENT SUMMARY

We reviewed differences in patient reports of their outcomes and experiences after surgical prostate removal, radiotherapy, or active surveillance for prostate cancer. We found differences in the effects on urinary, bowel, and sexual functions among the treatments, but no difference for mental or physical quality of life. Our results can help doctors and prostate cancer patients in shared decision-making.

Urologist communication is a primary factor leading to erectile dysfunction treatment postprostatectomy

BACKGROUND

Studies have shown insufficient utilization of care for patients with erectile dysfunction (ED) after radical prostatectomy (RP).

AIM

The aim of this study was to evaluate variables associated with barriers to seeking and receiving ED treatment.

METHODS

In this multicenter prospective cross-sectional study, the functional outcomes of 936 patients were assessed 10 to 15 years after RP. A total of 525 patients with ED or incontinence were asked about their treatment experiences or lack thereof. The data were analyzed using the chi-square test, t test, and multivariate logistic analyses.

OUTCOMES

Patients answered validated questionnaires regarding information sources, communication with their partner and urologist, and barriers to ED treatment.

RESULTS

Of the 525 patients, 80 were not available to survey. A total of 304 patients answered the survey (response: 68.0%). A total of 246 patients had ED and were included in this study. The mean age at surgery was 64.4 ± 6.1 years, and the mean age at the time of this survey was 77.1 ± 6.2 years. The mean follow-up duration was 12.7 ± 1.5 years. Forty-six percent (n = 114 of 246) of the patients had never received ED treatment. The most important conversation partners regarding the ED were the partner (69% [n = 169 of 246]) and the urologist (48% [n = 118 of 246]). Patients who never received ED treatment were less likely to have conversations with their urologist (34% vs 60%; P < .001), had less support (51% vs 68%; P = .01), and had less interest in sex from their partner (20% vs 40%; P = .001). Communication with other groups (general practitioners, other physicians, family, friends, and the Internet) had no influence on ED treatment utilization. The most relevant barrier to receiving ED treatment was the belief that treatment would not help (65%). No interest in sex from their partner (odds ratio, 3.9) and no conversation with their urologist about ED (odds ratio, 2.9) were found to be independent predictors of not receiving ED treatment.

CLINICAL IMPLICATIONS

Urologists should have enhanced awareness of how to approach patients directly about their ED and actively offer them treatment options.

STRENGTHS AND LIMITATIONS

These results should be further validated in a multicenter, prospective study. Response bias may have affected the results. Furthermore, the current cohort was relatively old.

CONCLUSION

This study revealed that no interest in sex from one's partner and insufficient communication with a urologist were relevant barriers to insufficient utilization of ED treatment after RP.

A review of core outcome sets (COS) developed for different settings finds there is a subset of outcomes relevant for both research and routine care

OBJECTIVES

To compare the outcomes selected for the same condition in core outcome sets (COSs) for research with those in COS for the routine care setting.

METHODS

A sample of COS was created from the most frequent five health areas within previous systematic reviews of COS for research and COS for routine care. Outcomes were extracted and categorized using an outcome taxonomy. Frequency of outcome domains included within COS were analyzed in subgroups according to research or care setting, patient involvement in COS development and health area. Matched sets of COS were created, where at least one research COS and one routine care COS exist for the same health condition, to identify the outcomes that were recommended for both settings. A similar process was used for a subset of paired COS matched in scope for both intervention and population as well as health condition.

RESULTS

The sample of COS comprised: 246 COS for research only, 76 COS for routine care only and 55 COS for both research and routine care. Across the 18 sets matched by health condition the median number (range) of outcomes included in both research COS and routine care COS was 6 (3-15), with differences noted across health areas. For the 11 paired COS matched by scope and health condition, the corresponding figures were 2 (2-8). Across all settings, COS that did not include patients as participants were less likely to include life impact outcomes.

CONCLUSION

Within a given health condition, a small number of core outcomes were found to be relevant for both research and care, offering a meaningful starting point for linking research and real-world evaluation.

Online decision aid for patients with prostate cancer evaluated by 11 290 patients and 91 urologists in Germany

OBJECTIVE

To evaluate the nationwide online decision aid 'Entscheidungshilfe Prostatakrebs' (established in 2016, >11.000 users and 60 new users/week) for patients with non-metastatic prostate cancer (PCa), from the perspective of patients and urologists.

PATIENTS AND METHODS

To provide personalised information, the tool collects most of the International Consortium for Health Outcomes Measurement standard set, personal preferences, psychological features, and a validated rating of the tool. To evaluate urologists' opinions, we developed a structured two-page questionnaire. All data were collected anonymously.

RESULTS

From June 2016 to December 2020, 11 290 patients used the PCa decision aid. Their median (interquartile range [IQR]) age was 67 (61-72) years. The median (IQR) time from initial diagnosis to using the tool was 4 (3-7) weeks. In all, 87.7% of users reported high satisfaction. In a multivariable model, predictors for considering observation were higher knowledge, using the decision aid alone, lower oncological risk, normal erectile function, and respective personal preferences. Of 194 urologists, 91 (47%) had implemented the decision aid in their clinical practice. The urologists' mean (SD) satisfaction score (1 'very good'; 6 'unsatisfactory') with it was 1.45 (0.55), and 92% recommended it. Half of the urologists reported time savings.

CONCLUSION

Patients and urologists report a very high level of acceptance and satisfaction with this online tool. It offers advantages in shared decision-making and time efficiency. The usage of the decision aid might improve the adoption of active surveillance and watchful waiting when indicated.

International Variations in Surgical Quality of Care in Men With Prostate Cancer: Results From the TrueNTH Global Registry

PURPOSE

Functional problems such as incontinence and sexual dysfunction after radical prostatectomy (RP) are important outcomes to evaluate surgical quality in prostate cancer (PC) care. Differences in survival after RP between countries are known, but differences in functional outcomes after RP between providers from different countries are not well described.

METHODS

Data from a multinational database of patients with PC (nonmetastatic, treated by RP) who answered the EPIC-26 questionnaire at baseline (before RP, T0) and 1 year after RP (T1) were used, linking survey data to clinical information. Casemix-adjusted incontinence and sexual function scores (T1) were calculated for each country and provider on the basis of regression models and then compared using minimally important differences (MIDs).

RESULTS

A total of 21,922 patients treated by 151 providers from 10 countries were included. For the EPIC-26 incontinence domain, the median adjusted T1 score of countries was 76, with one country performing more than one MID (for incontinence: 6) worse than the median. Eighteen percent of the variance (R2) of incontinence scores was explained by the country of the providers. The median adjusted T1 score of sexual function was 33 with no country performing perceivably worse than the median (more than one MID worse), and 34% (R2) of the variance of the providers' scores could be explained by country.

CONCLUSION

To our knowledge, this is the first comparison of functional outcomes 1 year after surgical treatment of patients with PC between different countries. Country is a relevant predictor for providers' incontinence and sexual function scores. Although the results are limited because of small samples from some countries, they should be used to enhance cross-country initiatives on quality improvement in PC care.

Individualized center-based analysis of urinary and sexual functional outcome after radical prostatectomy based on the prostate cancer outcome study: a post hoc pathway to patient outcome measurement analysis for quality improvement

PURPOSE

We evaluate differences of patient-reported outcome measurements (PROM) based urinary continence and sexual function 12 months after radical prostatectomy (RPE) based on perioperative, surgical, and patient-specific characteristics in a large European academic urology center.

MATERIALS AND METHODS

All men enrolled in the Prostate Cancer Outcome Study (PCO) study who were treated with RPE between 2017 and 2021 completed EPIC-26 information surveys before and 12 months after RPE. Survey data were linked to clinical data of our institution. Logistic regression analyses were performed to examine the correlation between individual surgeons, patient characteristics, patient clinical data, and their urinary continence and sexual function.

RESULTS

In total, data of 429 men were analyzed: unstratified mean (SD) EPIC-26 domain score for urinary function decreased from 93.3 (0.7) to 60.4 (1.5) one year after RPE, respectively for sexual function from 64.95 (1.6) to 23.24 (1.1). Patients with preoperative adequate urinary function (EPIC-26 score > 80) reported significantly different mean urinary function scores between 53.35 (28.88) and 66.25 (25.15), p= 0.001, stratified by surgeons experience. On binary logistic regression analyses, only nerve sparing techniques (OR: 1,83, 95% CI: 1.01;3.21; p = 0.045) and low body mass index (OR: 0.91, CI: 0.85;0.99, p= 0.032) predicted adequate postoperative urinary function.

CONCLUSIONS

The results show how using provider-specific data from a larger cohort study enables to develop institution-specific analysis for functional outcomes after RPE. These models can be used for internal quality improvement as well as enhanced and provider-specific patient communication and shared decision making.

Surgical approach affecting long-term urinary continence status after robot-assisted laparoscopic prostatectomy prospectively evaluated using self-reported functional status (Expanded Prostate Cancer Index Composite, EPIC-26)

Purpose

The aim of the study was to examine the influence of the surgical approach for robot-assisted laparoscopic prostatectomy (RALP) on long-term urinary continence status in the era of self-reported functional status measures using the Expanded Prostate Cancer Index Composite 26.

Materials and methods

This is a prospective evaluation of 232 patients undergoing RALP between September, 2019 and September, 2020. Urinary continence status and postoperative incontinence (pad usage) were evaluated 12 months after RALP using Expanded Prostate Cancer Index Composite 26 questionnaires. Patients were categorized according to their surgical approach and outcome into the following groups: successful nerve sparing (NS), primarily without nerve sparing (prim. NNS), and no nerve sparing by secondary resection (NNS by SR). The median levels of their questionnaire outcomes were evaluated and compared using the Wilcoxon rank sum test with continuity correction.

Results

Urinary continence status 12 months after RALP differed significantly between the NS and prim. NNS (p = 0.0071) and the NS and NNS by SR (p = 0.0076) groups. There was no significant difference between the prim. NNS and NNS by SR (p = 0.53) groups. Pad usage 12 months after RALP had no significant difference with regard to SR of the neurovascular bundle (p = 0.14).

Conclusions

Patient-reported outcomes of long-term urinary continence status seem to show no difference in postoperative continence, regardless of whether a non-nerve-sparing result was planned or reached through SR. Instead, preservation of neurovascular bundle seems to lead to better long-term continence rates.

Radiation therapy margin reduction for patients with localized prostate cancer: A prospective study of the dosimetric impact and quality of life

OBJECTIVES

To investigate the impact of reducing Clinical Target Volume (CTV) to Planning Target Volume (PTV) margins on delivered radiation therapy (RT) dose and patient reported quality-of-life (QOL) for patients with localized prostate cancer.

METHODS

Twenty patients were included in a single institution IRB-approved prospective study. Nine were planned with reduced margins (4 mm at prostate/rectum interface, 5 mm elsewhere), and 11 with standard margins (6/10 mm). Cumulative delivered dose was calculated using deformable dose accumulation. Each daily CBCT dataset was deformed to the planning CT (pCT), dose was computed, and accumulated on the resampled pCT using a parameter-optimized, B-spline algorithm (Elastix, ITK/VTK). EPIC-26 patient reported QOL was prospectively collected pre-treatment, post-treatment, and at 2-, 6-, 12-, 18-, 24-, 36-, 48-, and 60-month follow-ups. Post -RT QOL scores were baseline corrected and standardized to a [0-100] scale using EPIC-26 methodology. Correlations between QOL scores and dosimetric parameters were investigated, and the overall QOL differences between the two groups (QOLMargin-reduced -QOLcontrol ) were calculated.

RESULTS

The median QOL follow-up length for the 20 patients was 48 months. Difference between delivered dose and planned dose did not reach statistical significance (p > 0.1) for both targets and organs at risk between the two groups. At 4 years post-RT, standardized mean QOLMargin-reduced -QOLcontrol were improved for Urinary Incontinence, Urinary Irritative/Obstructive, Bowel, and Sexual EPIC domains by 3.5, 14.8, 10.2, and 16.1, respectively (higher values better). The control group showed larger PTV/rectum and PTV/bladder intersection volumes (7.2 ± 5.8, 18.2 ± 8.1 cc) than the margin-reduced group (2.6 ± 1.8, 12.5 ± 8.3 cc), though the dose to these intersection volumes did not reach statistical significance (p > 0.1) between the groups. PTV/rectum intersection volume showed a moderate correlation (r = -0.56, p < 0.05) to Bowel EPIC domain.

CONCLUSIONS

Results of this prospective study showed that margin-reduced group exhibited clinically meaningful improvement of QOL without compromising the target dose coverage.

Regional Collaboration and Trends in Clinical Management of Thyroid Cancer

OBJECTIVE

This study examines the trends in the management of thyroid cancer and clinical outcomes in the Southwestern region of The Netherlands from 2010 to 2021, where a regional collaborative network has been implemented in January 2016.

STUDY DESIGN

Retrospective cohort study.

SETTING

This study encompasses all patients diagnosed with thyroid cancer of any subtype between January 2010 and June 2021 in 10 collaborating hospitals in the Southwestern region of The Netherlands.

METHODS

The primary outcome of this study was the occurrence of postoperative complications. Secondary outcomes were trends in surgical management, centralization, and waiting times of patients with thyroid cancer.

RESULTS

This study included 1186 patients with thyroid cancer. Median follow-up was 58 [interquartile range: 24-95] months. Surgery was performed in 1027 (86.6%) patients. No differences in postoperative complications, such as long-term hypoparathyroidism, permanent recurrent nerve paresis, or reoperation due to bleeding were seen over time. The percentage of patients with low-risk papillary thyroid carcinoma referred to the academic hospital decreased from 85% (n = 120/142) in 2010 to 2013 to 70% (n = 120/171) in 2014 to 2017 and 62% (n = 100/162) in 2018 to 2021 (P < .01). The percentage of patients undergoing a hemithyroidectomy alone was 9% (n = 28/323) in 2010 to 2013 and increased to 20% (n = 63/317; P < .01) in 2018 to 2021.

CONCLUSION

The establishment of a regional oncological network coincided with a de-escalation of thyroid cancer treatment and centralization of complex patients and interventions. However, no differences in postoperative complications over time were observed. Determining the impact of regional oncological networks on quality of care is challenging in the absence of uniform quality indicators.

[Urinary incontinence after radical prostatectomy for prostate cancer-data from 17,149 patients from 125 certified centers]

BACKGROUND

In addition to erectile dysfunction, urinary incontinence is the most common functional limitation after radical prostatectomy (RPE) for prostate cancer (PCa). The German S3 guideline recommends informing patients about possible effects of the therapy options, including incontinence. However, only little data on continence from routine care in German-speaking countries after RPE are currently available, which makes it difficult to inform patients.

OBJECTIVE

The aim of this work is to present data on the frequency and severity of urinary incontinence after RPE from routine care.

MATERIALS AND METHODS

Information from the PCO (Prostate Cancer Outcomes) study is used, which was collected between 2016 and 2022 in 125 German Cancer Society (DKG)-certified prostate cancer centers in 17,149 patients using the Expanded Prostate Cancer Index Composite Short Form (EPIC-26). Changes in the "incontinence" score before (T0) and 12 months after RPE (T1) and the proportion of patients who used pads, stratified by age and risk group, are reported.

RESULTS

The average score for urinary incontinence (value range: 0-worst possible to 100-best possible) was 93 points at T0 and 73 points 12 months later. At T0, 97% of the patients did not use a pad, compared to 56% at T1. 43% of the patients who did not use a pad before surgery used at least one pad a day 12 months later, while 13% use two or more. The proportion of patients using pads differs by age and risk classification.

CONCLUSION

The results provide a comprehensive insight into functional outcome 12 months after RPE and can be taken into account when informing patients.

Comparative effectiveness of new treatment modalities for localized prostate cancer through patient-reported outcome measures

Purpose

There is scarce comparative effectiveness research on the new treatment modalities for localized prostate cancer. We aim to compare through Patient-Reported Outcome Measures (PROMs) the impact of active surveillance, robot-assisted radical prostatectomy (RARP), intensity-modulated radiotherapy (IMRT), and real-time brachytherapy, considering side effects (incontinence, irritative/obstructive urinary symptoms, sexual dysfunction and bowel symptoms) and physical and mental health.

Materials and Methods

Prospective cohort of men diagnosed with clinically localized prostate cancer (age 50-75y, T1-T2, and low risk including Gleason 3 + 4 in T1c) from 18 Spanish hospitals, followed up to 24 months. Treatment decisions were jointly made by patients and physicians (n = 572). The Expanded Prostate cancer Index Composite (EPIC-26) and Short-Form 36 (SF-36v2) were administered through telephone interviews before and three, six, 12, and 24 months after treatment. To account for correlation among repeated measures, generalized estimating equation models were constructed. All analyses were performed with propensity score weights to solve treatment selection bias.

Results

The PROMs completion rate at 24 months was 95.0 %. Active surveillance entails the fewest side effects, but with significant sexual (0.4 standard deviations [SD], p < 0.001) and physical health deterioration (0.5 SD, p < 0.001); and moderate mental health improvement (0.4 SD, p = 0.001) at 24 months. Compared with active surveillance, RARP presented greater urinary incontinence (p = 0.030), and IMRT and real-time brachytherapy worse bowel symptoms (p = 0.027 and p = 0.007) at 24 months.

Conclusions

Most side effects of the new treatment modalities seem to be limited to short-term deteriorations, except for moderate-large urinary incontinence in patients who had undergone RARP and moderate bowel deterioration in patients treated with IMRT or with real-time brachytherapy. Furthermore, patients under active surveillance, IMRT, and real-time brachytherapy showed a moderate improvement in mental health.

Psychometric validation of the Spanish version of the Expanded Prostate Cancer Index Composite-26

PURPOSE

To assess the validity, reliability, and responsiveness of the Spanish version of the Expanded Prostate cancer Index Composite (EPIC) with 26 items.

METHODS

Multicentric longitudinal study of patients diagnosed with localized or locally advanced prostate cancer (any T, any N, M0) treated with active surveillance, surgery, external radiotherapy, or brachytherapy. The EPIC-50 was administered initially to the cohort (n = 324 patients), until it was replaced in November 2019 by the EPIC-26 (n = 543), in both groups before treatment and 12 months after. We assessed confirmatory factor analysis (CFA), reliability with Cronbach's alpha coefficient, criterion validity with the intraclass correlation coefficient (ICC), and responsiveness by testing a priori hypotheses on deterioration effect size (ES).

RESULTS

The CFA confirmed the five-domain structure of the EPIC-26 proposed by the original instrument (comparative fit index = 0.95). The agreement between EPIC-50 (gold standard) and EPIC-26 domains was excellent (ICC > 0.90). Cronbach's alpha was > 0.7 in almost all domains, and the floor effect was near zero, although ceiling effect was higher than 50% in urinary incontinence and bowel domains. Hypothesized changes between before and 12 months after treatment were confirmed: ES > 0.8 in both urinary incontinence and sexual domains among patients who underwent surgery; and ES ranging 0.44-0.48 for bowel and sexual domains in patients treated with external radiotherapy.

CONCLUSION

The Spanish version of the EPIC-26 has demonstrated adequate metric properties, similar to those of the original version, with acceptable goodness-of-fit indices, good criterion validity, reliability, and responsiveness to detect changes after radical prostatectomy or external radiotherapy.

Prediction models of incontinence and sexual function one year after radical prostatectomy based on data from 20 164 prostate cancer patients

BACKGROUND

Incontinence and sexual dysfunction are long-lasting side effects after surgical treatment (radical prostatectomy, RP) of prostate cancer (PC). For an informed treatment decision, physicians and patients should discuss expected impairments. Therefore, this paper firstly aims to develop and validate prognostic models that predict incontinence and sexual function of PC patients one year after RP and secondly to provide an online decision making tool.

METHODS

Observational cohorts of PC patients treated between July 2016 and March 2021 in Germany were used. Models to predict functional outcomes one year after RP measured by the EPIC-26 questionnaire were developed using lasso regression, 80-20 splitting of the data set and 10-fold cross validation. To assess performance, R2, RMSE, analysis of residuals and calibration-in-the-large were applied. Final models were externally temporally validated. Additionally, percentages of functional impairment (pad use for incontinence and firmness of erection for sexual score) per score decile were calculated to be used together with the prediction models.

RESULTS

For model development and internal as well as external validation, samples of 11 355 and 8 809 patients were analysed. Results from the internal validation (incontinence: R2 = 0.12, RMSE = 25.40, sexual function: R2 = 0.23, RMSE = 21.44) were comparable with those of the external validation. Residual analysis and calibration-in-the-large showed good results. The prediction tool is freely accessible: https://nora-tabea.shinyapps.io/EPIC-26-Prediction/.

CONCLUSION

The final models showed appropriate predictive properties and can be used together with the calculated risks for specific functional impairments. Main strengths are the large study sample (> 20 000) and the inclusion of an external validation. The models incorporate meaningful and clinically available predictors ensuring an easy implementation. All predictions are displayed together with risks of frequent impairments such as pad use or erectile dysfunction such that the developed online tool provides a detailed and informative overview for clinicians as well as patients.

Patient-reported outcomes before treatment for localized prostate cancer: are there differences among countries? Data from the True North Global Registry

INTRODUCTION

Similar Patient-Reported Outcomes (PROs) at diagnosis for localized prostate cancer among countries may indicate that different treatments are recommended to the same profile of patients, regardless the context characteristics (health systems, medical schools, culture, preferences…). The aim of this study was to assess such comparison.

METHODS

We analyzed the EPIC-26 results before the primary treatment of men diagnosed of localized prostate cancer from January 2017 onwards (revised data available up to September 2019), from a multicenter prospective international cohort including seven regions: Australia/New Zealand, Canada, Central Europe (Austria / Czech Republic / Germany), United Kingdom, Italy, Spain, and the United States. The EPIC-26 domain scores and pattern of three selected items were compared across regions (with Central Europe as reference). All comparisons were made stratifying by treatment: radical prostatectomy, external radiotherapy, brachytherapy, and active surveillance.

RESULTS

The sample included a total of 13,483 men with clinically localized or locally advanced prostate cancer. PROs showed different domain patterns before treatment across countries. The sexual domain was the most impaired, and the one with the highest dispersion within countries and with the greatest medians' differences across countries. The urinary incontinence domain, together with the bowel and hormonal domains, presented the highest scores (better outcomes) for all treatment groups, and homogeneity across regions.

CONCLUSIONS

Patients with localized or locally advanced prostate cancer undergoing radical prostatectomy, EBRT, brachytherapy, or active surveillance presented mainly negligible or small differences in the EPIC-26 domains before treatment across countries. The results on urinary incontinence or bowel domains, in which almost all patients presented the best possible score, may downplay the baseline data role for evaluating treatments' effects. However, the heterogeneity within countries and the magnitude of the differences found across countries in other domains, especially sexual, support the need of implementing the PRO measurement from diagnosis.

Late, persistent, substantial treatment-related symptoms (LAPERS) following low-dose-rate brachytherapy for prostate cancer

PURPOSE

We aim to report 1) prevalence, 2) incidence, and 3) late, persistent, substantial treatment-related symptoms (LAPERS) after low-dose-rate brachytherapy (LDRBT) for prostate cancer.

METHODS AND MATERIALS

The study comprised men treated with LDRBT in a single Australian institution between 2014 and 2019. All men completed the Expanded Prostate Cancer Index Composite 26 (EPIC-26) questionnaire pretreatment, and at regular intervals posttreatment. 'Substantial' symptoms were defined as 'moderate' or 'big' problems in EPIC-26 which assesses the degree of symptom bother for each functional domain. 'Persistent' symptoms were defined as 'substantial' symptoms that present in at least half of the 'late' followup assessments. This provided a binary LAPERS outcome (yes/no). Prevalence (at each time point) and cumulative incidence of substantial symptoms were also reported.

RESULTS

A total of 172 men with 'baseline' and at least three 'late' followup EPIC-26 were included in the study. The median followup was 60 months (IQR: 36-74 months). For overall urinary function, prevalence of substantial symptoms was highest at 10% 6-month posttreatment, with 5-year cumulative incidence of 18%, but only 2% had LAPERS. For overall bowel function, prevalence of substantial symptoms was highest at 7% 12-months posttreatment, with 5-year cumulative incidence of 15%, and only 2% had LAPERS. For sexual function, prevalence of substantial symptoms was highest at 28% 6-months posttreatment, with 5-year cumulative incidence of 49%, and 22% had LAPERS (baseline-adjusted LAPERS 17%).

CONCLUSIONS

There were considerable differences in late toxicities using different toxicity-reporting approaches. LAPERS approach is more reflective of 'true' late toxicities considering duration and persistence of symptoms.

Identification of Key Elements in Prostate Cancer for Ontology Building via a Multidisciplinary Consensus Agreement

BACKGROUND

Clinical data collection related to prostate cancer (PCa) care is often unstructured or heterogeneous among providers, resulting in a high risk for ambiguity in its meaning when sharing or analyzing data. Ontologies, which are shareable formal (i.e., computable) representations of knowledge, can address these challenges by enabling machine-readable semantic interoperability. The purpose of this study was to identify PCa-specific key data elements (KDEs) for standardization in clinic and research.

METHODS

A modified Delphi method using iterative online surveys was performed to report a consensus agreement on KDEs by a multidisciplinary panel of 39 PCa specialists. Data elements were divided into three themes in PCa and included (1) treatment-related toxicities (TRT), (2) patient-reported outcome measures (PROM), and (3) disease control metrics (DCM).

RESULTS

The panel reached consensus on a thirty-item, two-tiered list of KDEs focusing mainly on urinary and rectal symptoms. The Expanded Prostate Cancer Index Composite (EPIC-26) questionnaire was considered most robust for PROM multi-domain monitoring, and granular KDEs were defined for DCM.

CONCLUSIONS

This expert consensus on PCa-specific KDEs has served as a foundation for a professional society-endorsed, publicly available operational ontology developed by the American Association of Physicists in Medicine (AAPM) Big Data Sub Committee (BDSC).

A joint international consensus statement for measuring quality of survival for patients with childhood cancer

The aim of treating childhood cancer remains to cure all. As survival rates improve, long-term health outcomes increasingly define quality of care. The International Childhood Cancer Outcome Project developed a set of core outcomes for most types of childhood cancers involving relevant international stakeholders (survivors; pediatric oncologists; other medical, nursing or paramedical care providers; and psychosocial or neurocognitive care providers) to allow outcome-based evaluation of childhood cancer care. A survey among healthcare providers (n = 87) and online focus groups of survivors (n = 22) resulted in unique candidate outcome lists for 17 types of childhood cancer (five hematological malignancies, four central nervous system tumors and eight solid tumors). In a two-round Delphi survey, 435 healthcare providers from 68 institutions internationally (response rates for round 1, 70-97%; round 2, 65-92%) contributed to the selection of four to eight physical core outcomes (for example, heart failure, subfertility and subsequent neoplasms) and three aspects of quality of life (physical, psychosocial and neurocognitive) per pediatric cancer subtype. Measurement instruments for the core outcomes consist of medical record abstraction, questionnaires and linkage with existing registries. This International Childhood Cancer Core Outcome Set represents outcomes of value to patients, survivors and healthcare providers and can be used to measure institutional progress and benchmark against peers.

[The interoperability of IIEF-5 with EPIC-26 : Sexual function after radical prostatectomy]

BACKGROUND

In the past, the IIEF‑5 (International Index of Erectile Function 5 ) was predominantly used to measure erectile function in prostate cancer patients. Following international developments, the domain "sexuality" of the EPIC-26 (Expanded Prostate Cancer Index Composite 26) is increasingly used in Germany.

OBJECTIVE

The aim of this work is to create a practicable comparison of the domain "sexuality" of the EPIC-26 with the IIEF‑5 for treatment in Germany. This is particularly necessary for the evaluation of historical patient collectives.

MATERIALS AND METHODS

For the evaluation, 2123 patients with prostate cancer confirmed by biopsy from 2014-2017 who completed both the IIEF‑5 and the EPIC-26 were considered. Linear regression analyses are calculated to convert IIEF‑5 sum scores to EPIC-26 sexuality domain scores.

RESULTS

The correlation between IIEF‑5 and the EPIC-26 domain score "sexuality" was 0.74, suggesting a high degree of content convergence between the constructs measured. While the standard error of the predicted values is relatively small, the prediction intervals are very wide. For example, for the critical IIEF‑5 value of 22, the predicted value is 78.88 with a 95% prediction interval of 55.09 to 102.66.

CONCLUSION

IIEF‑5 and the Sexuality scale of the EPIC-26 measure a similar construct. The analysis shows that conversion of individual values is associated with great uncertainty. However, at the group level, the observed EPIC-26 "sexuality" score could be predicted quite accurately. This opens up the possibility of comparing the erectile function of cohorts of patients/test persons, even if this was collected with different measuring instruments.

Selecting a PRO-CTCAE-based subset for patient-reported symptom monitoring in prostate cancer patients: a modified Delphi procedure

BACKGROUND

Clinician-based reporting of adverse events leads to underreporting and underestimation of the impact of adverse events on prostate cancer patients. Therefore, interest has grown in capturing adverse events directly from patients using the Patient-Reported Outcomes (PROs) version of the Common Terminology Criteria for Adverse Events (CTCAE). We aimed to develop a standardized PRO-CTCAE subset tailored to adverse event monitoring in prostate cancer patients.

MATERIALS AND METHODS

We used a mixed-method approach based on the 'phase I guideline for developing questionnaire modules' by the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life group, including a literature review, and interviews with patients (n = 30) and health care providers (HCPs, n = 16). A modified Delphi procedure was carried out to reach consensus on the final subset selected from the complete PRO-CTCAE item library.

RESULTS

Fourteen multidisciplinary HCPs and 12 patients participated in the Delphi rounds. Ninety percent agreed on the final subset, consisting of: 'ability to achieve and maintain erection', 'decreased libido', 'inability to reach orgasm', 'urinary frequency', 'urinary urgency', 'urinary incontinence', 'painful urination', 'fecal incontinence', 'fatigue', 'hot flashes', 'feeling discouraged', 'sadness', and 'concentration'. From 16 articles identified in the literature review, the following adverse events for which no PRO-CTCAE items are available, were included to the recommendation section: 'nocturia', 'blood and/or mucus in stool', 'hemorrhoids', 'hematuria', 'cystitis', 'neuropathy', and 'proctitis'.

CONCLUSIONS

The obtained PRO-CTCAE-subset can be used for multidisciplinary adverse event monitoring in prostate cancer care. The described method may guide development of future PRO-CTCAE subsets.

Mortality and biochemical recurrence after surgery, brachytherapy, or external radiotherapy for localized prostate cancer: a 10-year follow-up cohort study

To compare the effectiveness at ten years of follow-up of radical prostatectomy, brachytherapy and external radiotherapy, in terms of overall survival, prostate cancer-specific mortality and biochemical recurrence. Cohort of men diagnosed with localized prostate cancer (T1/T2 and low/intermediate risk) from ten Spanish hospitals, followed for 10 years. The treatment selection was decided jointly by patients and physicians. Of 704 participants, 192 were treated with open radical retropubic prostatectomy, 317 with ¹²⁵I brachytherapy alone, and 195 with 3D external beam radiation. We evaluated overall survival, prostate cancer-specific mortality, and biochemical recurrence. Kaplan–Meier estimators were plotted, and Cox proportional-hazards regression models were constructed to estimate hazard ratios (HR), adjusted by propensity scores. Of the 704 participants, 542 patients were alive ten years after treatment, and a total of 13 patients have been lost during follow-up. After adjusting by propensity score and Gleason score, brachytherapy and external radiotherapy were not associated with decreased 10-year overall survival (aHR = 1.36, p = 0.292 and aHR = 1.44, p = 0.222), but presented higher biochemical recurrence (aHR = 1.93, p = 0.004 and aHR = 2.56, p < 0.001) than radical prostatectomy at ten years of follow-up. Higher prostate cancer-specific mortality was also observed in external radiotherapy (aHR = 9.37, p = 0.015). Novel long-term results are provided on the effectiveness of brachytherapy to control localized prostate cancer ten years after treatment, compared to radical prostatectomy and external radiotherapy, presenting high overall survival, similarly to radical prostatectomy, but higher risk of biochemical progression. These findings provide valuable information to facilitate shared clinical decision-making.

Balancing adaptability and standardisation: insights from 27 routinely implemented ICHOM standard sets

BACKGROUND

Healthcare systems around the world experience increasing pressure to control future growth of healthcare expenditures. Among other initiatives, quality and value-based benchmarking has become an important field to inform clinical evaluation and reimbursement questions. The International Consortium for Health Outcomes Measurement (ICHOM) has become one of the driving forces to translate scientific evidence into standardized assessments that are routinely applicable in day-to-day care settings. These aim to provide a benchmarking tool that allows the comparison and competition of health care delivery on the basis of value-based health care principles.

METHODS

This work focuses on the consolidation of the ICHOM methodology and presents insights from 27 routinely implemented Standard Sets. The analysis is based on a literature review of the ICHOM literature repository, a process document review and key informant interviews with ICHOM's outcomes research and development team.

RESULTS

Key findings are that the scope of ICHOM Standard Sets shifted from a more static focus on burden of disease and poorly standardized care pathways to a more dynamic approach that also takes into account questions about the setting of care, feasibility of implementing a benchmarking tool and compatibility of different Standard Sets. Although certain overlaps exist with other initiatives in the field of patient reported outcomes (PRO), their scopes differ significantly and they hence rather complement each other. ICHOM pursues a pragmatic approach to enable the benchmarking and the analysis of healthcare delivery following the principles of value-based healthcare.

CONCLUSION

The ICHOM Standard Sets complement other initiatives in the field of patient-reported outcomes (PRO) and functional reporting by placing a particular focus on healthcare delivery, while other initiatives primarily focus on evaluation of academic endpoints. Although ICHOM promotes a pragmatic approach towards developing and devising its Standard Sets, the definition of standardized decision making processes emerged as one of the key challenges. Furthermore, the consolidation of core metrics across number of disease areas to enable the parallel implementation of different Standard Sets in the same care setting is an important goal that will enable the widespread implementation of patient-reported outcome measures (PROM).

Real-world utilisation of brachytherapy boost and patient-reported functional outcomes in men who had external beam radiation therapy for prostate cancer in Australia

Background and purpose

We aimed to evaluate utilisation of brachytherapy (BT) boost in men who had external beam radiation therapy (EBRT) for prostate cancer, and to compare patient-reported functional outcomes (PRO) following each approach in a population-based setting in Australia.

Materials and methods

This is a population-based cohort of men with localised prostate cancer enrolled in the Victorian Prostate Cancer Outcomes Registry, who had EBRT between 2015 and 2020. Primary outcomes were proportion who had BT-boost, and PRO (assessed using the EPIC-26 questionnaires) 12 months post-treatment. Multivariable logistic regressions were used to evaluate factors associated with BT-boost, and linear regressions were used to estimate differences in EPIC-26 domain scores between EBRT alone and EBRT + BT.

Results

Of the 1,626 men in the study, 88 (5.4 %) had BT-boost. Factors independently associated with BT-boost were younger age, higher socioeconomic status, and treatment in public institutions. 1,555 men completed EPIC-26 questionnaires. No statistically or clinically significant differences in EPIC-26 urinary, sexual and bowel functional domain scores were observed between men who had EBRT + BT vs EBRT alone, with adjusted mean differences in urinary incontinence, urinary irritative/ obstruction, sexual, and bowel domain of 1.28 (95 %CI = -3.23 to 5.79), -2.87 (95 %CI = -6.46 to 0.73), 0.49 (95 %CI = -4.78 to 5.76), and 2.89 (95 %CI = -0.83 to 6.61) respectively.

Conclusion

1-in-20 men who had EBRT for prostate cancer had BT-boost. This is the first time that PRO following EBRT+/-BT is reported at a population-based level in Australia, with no evidence to suggest worse PRO with addition of BT-boost 12 months post-treatment.

Medium-term Oncological Efficacy and Patient-reported Outcomes After Focal High-intensity Focused Ultrasound: The FOXPRO Trial

BACKGROUND

Multiparametric magnetic resonance imaging (mpMRI)/transrectal ultrasound (TRUS) fusion-guided high-intensity focused ultrasound (HIFU) is a focal treatment option for MRI-visible localized prostate cancer (PCa). High-quality evidence regarding the clinical efficacy remains limited.

OBJECTIVE

To assess medium-term oncological efficacy along with patient-reported outcome measures (PROMs).

DESIGN, SETTING, AND PARTICIPANTS

This prospective single-center cohort study was performed from 2014 to 2020. Patients with primary International Society of Urological Pathologists (ISUP) grade group (GG) ≤2 by combined MRI/TRUS fusion and systematic prostate biopsy and prostate-specific antigen (PSA) <10 ng/ml were included.

INTERVENTION

MRI/TRUS fusion-guided focal HIFU therapy.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The primary outcome was the cancer-free rate of the HIFU-treated lesion by biopsy after 1 yr. Secondary endpoints included salvage treatment-free survival (STFS), metastasis-free survival (MFS), overall survival (OS), and PROMs according to International Consortium for Health Outcomes Measurement recommendations.

RESULTS AND LIMITATIONS

Fifty patients were included (median [range] age 68 [48-80] yr; median PSA 6.5 [1.2-9.9] ng/ml; GG 1 54% [n = 27], and GG 2 46% [n = 23]). The median (range) PSA decrease from baseline to 12 mo was 51% (35.9-72.7%). In total, 37/50 patients (74%) underwent a 1-yr biopsy. PCa was detected in 23 patients (46%; GG 1 20% [n = 10]; GG >1 26% [n = 13]; infield 40% [n = 20]). At a median follow-up of 42 (13-73) mo, PCa was detected in 30 men (60%). Among all patients, 19 (38%) underwent salvage treatments (median [95% confidence interval] STFS 53 [44.3-61.7] mo). MFS and OS were 100% and 98%, respectively. The Expanded Prostate Cancer Index Composite-26 sexual domain decreased by 20.8 points (p = 0.372).

CONCLUSIONS

MRI/TRUS-guided focal HIFU therapy results in complete cancer ablation in only half of the treated patients after 1 yr, with further recurrences at medium-term follow-up. A decline of potency occurs in a subset of patients.

PATIENT SUMMARY

Focal image-guided high-intensity focused ultrasound therapy controls cancer in one of two patients. Its impact on urinary continence and erectile function is low.

High Neuroticism Is Related to More Overall Functional Problems and Lower Function Scores in Men Who Had Surgery for Non-Relapsing Prostate Cancer

The personality trait of neuroticism is associated with adverse health outcomes after cancer treatment, but few studies concern men treated for prostate cancer. We examined men with high and low neuroticism treated with radical prostatectomy for curable prostate cancer without relapse. We compared overall problems and domain summary scores (DSSs) between these groups, and if high neuroticism at pre-treatment was a significant predictor of overall problems and DSSs at follow-up. A sample of 462 relapse-free Norwegian men self-rated neuroticism, overall problems, and DSSs by the EPIC-26 before surgery and at three years’ follow-up. Twenty-one percent of the sample had high neuroticism. Patients with high neuroticism reported significantly more overall problems and DSSs at pre-treatment. At follow-up, only overall bowel problems and urinary irritation/obstruction and bowel DSSs were different. High neuroticism was a significant predictor of overall bowel problems and bowel and irritation/obstruction DSSs at follow-up. High neuroticism at pre-treatment was significantly associated with a higher rate of overall problems both at pre-treatment and follow-up and had some significant predictions concerning bowel problems and urinary obstruction at follow-up. Screening for neuroticism at pre-treatment could identify patients in need of more counseling concerning later adverse health outcomes.

Quality measurement for cardiovascular diseases and cancer in hospital value-based healthcare: a systematic review of the literature

BACKGROUND

This systematic literature review identifies hospital value-based healthcare quality measures, measurement practices, and tools, as well as potential strategies for improving cardiovascular diseases and cancer care.

METHODS

A systematic search was carried out in the PubMed, Embase, CINAHL, and MEDLINE (OvidSP) databases. We included studies on quality measures in hospital value-based healthcare for cardiovascular diseases and cancer. Two reviewers independently screened titles and abstracts, conducted a full-text review of potentially relevant articles, assessed the quality of included studies, and extracted data thematically. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and four validated tools were used for methodological quality assessment.

RESULTS

The search yielded 2860 publications. After screening the titles and abstracts, 60 articles were retrieved for full-text review. A total of 37 studies met our inclusion criteria. We found that standardized outcome sets with patient involvement were developed for some cardiovascular diseases and cancer. Despite the heterogeneity in outcome measures, there was consensus to include clinical outcomes on survival rate and disease control, disutility of care, and patient-reported outcome measures such as long-term quality of life.

CONCLUSION

Hospitals that developed value-based healthcare or are planning to do so can choose whether they prefer to implement the standardized outcomes step-by-step, collect additional measures, or develop their own set of measures. However, they need to ensure that their performance can be consistently compared to that of their peers and that they measure what prioritizes and maximizes value for their patients.

Late Adverse Health Outcomes and Quality of Life after Curative Radiotherapy+ long-term ADT in Prostate Cancer Survivors:Comparison with men from the General Population

•

More than 5 years after radiotherapy for prostate cancer ) 54 % elderly patients report at least one moderate or big problem within the urinary, bowel or sexual domain. (Controls : 30%)

•

Such problems reduce Quality of Life., which, however ,is similar in the two cohorts , the least difference observed within the sexual domain.

Background

Few studies have described the impact of urinary, bowel and sexual Adverse Health Outcomes (AHOs) on Quality of Life (QoL) in Prostate Cancer Survivors living for more than 5 years after curative radiotherapy (“long-term PCaSs”), and compared the findings with those in men from general population. Here we assess self-reported AHOs in such PCaSs focusing on the association between problem experience and QoL. The findings are compared to corresponding symptoms in age-similar men from the general population without a PCa diagnosis (Norms).

Methods

Nine years (mean) after curative radiotherapy 1231 PCaSs and 3156 Norms completed the EPIC-26 questionnaire and the EORTC QLQ-C30 instrument. Domain Summary Scores (DSSs) for the urinary, bowel and sexual domains, the percentages of moderate/big dysfunctions and the proportions of overall problems were determined. Inter-cohort differences were interpreted based on cut-off values for published Minimal Clinically Important Differences (MCIDs). Multivariable linear regression models analyzed the associations between QoL and domain-related overall problems.

Results

Only the inter-cohort differences regarding bowel and sexual DSSs exceeded the respective MCIDs. Among PCaSs 54% had at least one moderate/big problem (Norms: 30%). In PCaSs and Norms, QoL increased with decreasing urinary and bowel problems, For sexuality this association was weaker in Norms and was almost lacking in PCaSs. Multivariable-adjusted QoL was similar in PCaSs and Norms, with general health being the strongest covariate.

Conclusions

During follow-up of long-term PCaSs health professionals should be aware of the survivors’ persisting moderate/big urinary, bowel or sexual problems associated with reduced QoL. In particular , alleviation of urinary and bowel problems can increase the men’s QoL.

The first patient-reported outcomes from the Utrecht Prostate Cohort (UPC): the first platform facilitating 'trials within cohorts' (TwiCs) for the evaluation of interventions for prostate cancer

Purpose

To describe the development and first outcomes of the Utrecht Prostate Cohort (UPC): the first ‘trials within cohorts’ (TwiCs) platform for prostate cancer (PCa).

Methods

All non-metastasized, histologically proven PCa patients who are planned to receive standard of care are eligible for inclusion in UPC. Patients provide informed consent for the collection of clinical and technical patient data, physician-reported outcomes, and patient-reported outcomes (PROs) up to 10 years post-treatment. Additionally, patients may provide broad consent for future randomization for experimental-intervention trials (TwiCs). Changes in PROs (EPIC-26 questionnaire domains) of the participants who received standard of care were analyzed using Wilcoxon signed-rank tests.

Results

In two years, 626 patients were enrolled, 503 (80.4%) of whom provided broad consent for future randomization. Among these, 293 (46.8%) patients underwent magnetic resonance-guided adaptive radiotherapy (MRgRT), 116 (18.5%) CT-guided external beam radiation therapy (EBRT), 109 (17.4%) robot-assisted radical prostatectomy (RARP), and 65 (10.4%) patients opted for active surveillance. Patients treated with MRgRT and CT-guided EBRT showed a transient but significant decline in urinary irritative/obstructive and bowel domain scores at 1-month follow-up. RARP patients showed a significant deterioration of urinary incontinence domain scores between baseline and all follow-up moments and significant improvement of urinary irritative/obstructive domain scores between baseline and 9- and 12-month follow-up. All radical treatment groups showed a significant decline in sexual domain scores during follow-up. Active surveillance patients showed no significant deterioration over time in all domains.

Conclusion

The first results from the UPC study show distinct differences in PROs between treatment options for PCa.

Variation across operating sites in urinary and sexual outcomes after radical prostatectomy in localized and locally advanced prostate cancer

PURPOSE

The extent of variation in urinary and sexual functional outcomes after radical prostatectomy (RPE) between prostate cancer (PC) operating sites remains unknown. Therefore, this analysis aims to compare casemix-adjusted functional outcomes (EPIC-26 scores incontinence, irritative/obstructive function and sexual function) between operating sites 12 months after RPE.

MATERIALS AND METHODS

Analysis of a cohort of 7065 men treated with RPE at 88 operating sites (prostate cancer centers, "PCCs") between 2016 and 2019. Patients completed EPIC-26 and sociodemographic information surveys at baseline and 12 months after RPE. Survey data were linked to clinical data. EPIC-26 domain scores at 12 months after RPE were adjusted for relevant confounders (including baseline domain score, clinical and sociodemographic information) using regression analysis. Differences between sites were described using minimal important differences (MIDs) and interquartile ranges (IQR). The effects of casemix adjustment on the score results were described using Cohen's d and MIDs.

RESULTS

Adjusted domain scores at 12 months varied between sites, with IQRs of 66-78 (incontinence), 89-92 (irritative/obstructive function), and 20-29 (sexual function). Changes in domain scores after casemix adjustment for sites ≥ 1 MID were noted for the incontinence domain (six sites). Cohen's d ranged between - 0.07 (incontinence) and - 0.2 (sexual function), indicating a small to medium effect of casemix adjustment.

CONCLUSIONS

Variation between sites was greatest in the incontinence and sexual function domains for RPE patients. Future research will need to identify the factors contributing to this variation.

Experience Measures after Radical Prostatectomy: A Register-Based Study Evaluating the Association between Patient-Reported Symptoms and Quality of Information

Patient-reported data are important for quality assurance and improvement. Our main aim was to investigate the association between patient-reported symptoms among patients undergoing radical prostatectomy and their perceived quality of information before treatment. In this single-centre study, 235 men treated with robotic-assisted radical prostatectomy (RARP) between August 2017 and June 2019, responded to a follow-up questionnaire 20−42 months after surgery. A logistic regression analysis was performed to assess the association between patient-reported symptoms, measured with Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP), and the perceived quality of information. Adverse effects were defined as a higher EPIC score at follow-up than at baseline. The majority (77%) rated the general information as good. Higher EPIC-CP at follow-up was significantly associated with lower perceived quality of information, also after adjustment for age and level of education (bivariate model OR 1.12, 95% CI 1.07; 1.16, p < 0.001 and multiple model OR 1.12 95% CI 1.08; 1.17, p < 0.001). The share who rated information as good was almost identical among those who reported more symptoms after treatment and those who reported less symptoms (78.3% and 79.2%). Consequently, adverse effects could not explain the results. Our findings suggest a need for improvement of preoperative communication.

Implementation of patient-reported outcome measures into health care for men with localized prostate cancer

Measuring treatment-related quality of life (QOL) has become an increasingly requisite component of delivering high-quality care for patients with prostate cancer. Patient-reported outcome measures (PROMs) have, therefore, become an important tool for understanding the adverse effects of radical prostate cancer treatment and have been widely integrated into clinical practice. By providing real-time symptom monitoring and improved clinical feedback to patients and providers, PRO assessment has led to meaningful gains in prostate cancer care delivery and quality improvement worldwide. By providing an avenue for benchmarking, collaboration and population health monitoring, PROMs have delivered substantial improvements beyond providing individual symptom feedback. However, multilevel barriers exist that need to be addressed before the routine implementation of PROMs is achieved. Improvements in collection, interpretation, standardization and reporting will be crucial for the continued implementation of PROM instruments in prostate cancer pathways.

PROM a contemporary approach to assessing the quality of life of patients with cancer

PRO (patient reported outcomes) is a patient's subjective assessment of health and quality of life, without interpretation by a specialist. PROM (patient reported outcomes measure) questionnaires are used to analyzing this data. Assessment of the quality of life is a perspective direction, which allows to improve the quality of medical care and treatment results. Today, there are many questionnaires PROM, their reliability and validity has been proven in numerous studies. Unified standards and methods for developing and evaluating questionnaires have been developed. Interest in the use of quality of life questionnaires is increasing constantly. However, studies analyzing the data of the PROM questionnaires are rarely found in the national literature. Quality of life is also poorly researched in clinical practice. The aim of the literature review is to present modern methods for assessing the quality of life of patients, especially with cancer. A review of the most widespread and reliable questionnaires and assessment instruments for the quality of life of a patient has been carried out. The analysis of world experience of their use in clinical practice, for patients with cancer has been performed. Examples of both general and specific questionnaires are given. PROM questionnaires are widely used among patients with cancer. However, incorrect use of PROMs is found in the literature, and in patients with certain nosologies PROM data studied poorly. Further analysis of the potential of PROM questionnaires implementation is required, as well as their translation and adaptation for use in Russian health care.

Patient activation and patient-reported outcomes of men from a community pharmacy lifestyle intervention after prostate cancer treatment

PURPOSE

To report patient activation, which is the knowledge, skills, and confidence in self-managing health conditions, and patient-reported outcomes of men after prostate cancer treatment from a community pharmacy lifestyle intervention.

METHODS

The 3-month lifestyle intervention was delivered to 116 men in nine community pharmacies in the UK. Patient Activation Measure (PAM) was assessed at baseline, 3 and 6 months. Prostate cancer-related function and quality of life were assessed using the European Prostate Cancer Index Composite (EPIC-26) and EuroQOL 5-dimension 5-level (EQ5D-5L) questionnaires at baseline and 6 months. Lifestyle assessments included Mediterranean Diet Adherence Screener (MEDAS) at baseline, 3 and 6 months and Godin Leisure Time Exercise Questionnaire (GLTEQ) at baseline and 3 months.

RESULTS

PAM score increased from 62 [95% CI 59-65] at baseline to 66 [64-69] after the intervention (p = 0.001) and remained higher at 6 months (p = 0.008). Scores for all the EPIC-26 domains (urinary, bowel and hormonal) were high at both assessments, indicating good function (between 74 [70-78] and 89 [86-91]), except sexual domain, where scores were much lower (21 [17-25] at baseline, increasing to 24 [20-28] at 6 months (p = 0.012)). In EQ5D-5L, 3% of men [1-9] reported self-care problems, while 50% [41-60] reported pain and discomfort, and no significant changes over time. Men who received androgen deprivation therapy, compared with those who did not, reported higher (better) urinary incontinence scores (p < 0.001), but lower (worse) scores in the urinary irritative/obstructive (p = 0.003), bowel (p < 0.001) and hormonal (p < 0.001) domains. Poor sexual function was common across all age groups irrespective of prostate cancer treatment.

CONCLUSIONS

The intervention led to significant improvements in patient activation, exercise and diet. Community pharmacy could deliver effective services to address sexual dysfunction, pain and discomfort which are common after prostate cancer.

Clinical Outcome Assessment in Cancer Rehabilitation and the Central Role of Patient-Reported Outcomes

The aim of cancer rehabilitation is to help patients regain functioning and social participation. In order to evaluate and optimize rehabilitation, it is important to measure its outcomes in a structured way. In this article, we review the different types of clinical outcome assessments (COAs), including Clinician-Reported Outcomes (ClinROs), Observer-Reported Outcomes (ObsROs), Performance Outcomes (PerfOs), and Patient-Reported Outcomes (PROs). A special focus is placed on PROs, which are commonly defined as any direct report from the patient about their health condition without any interpretation by a third party. We provide a narrative review of available PRO measures (PROMs) for relevant outcomes, discuss the current state of PRO implementation in cancer rehabilitation, and highlight trends that use PROs to benchmark value-based care. Furthermore, we provide examples of PRO usage, highlight the benefits of electronic PRO (ePRO) collection, and offer advice on how to select, implement, and integrate PROs into the cancer rehabilitation setting to maximize efficiency.

Bridging health technology assessment and healthcare quality improvement using international consortium of health outcomes measurement standard sets

Objective

Although health technology assessment (HTA) and healthcare quality improvement are distinct processes, a greater level of alignment in outcome measures used may increase the quality and efficiency of data collection. This study evaluates the agreement in outcome measures used in oncology for healthcare quality improvement and HTAs, and how these align to the International Consortium for Health Outcomes Measurement (ICHOM) standard sets.

Methods

We conducted a cross-sectional comparative analysis of ICHOM sets focusing on oncological indications and publicly available measures for healthcare quality and HTA reports published by the National Health Care Institute from the Netherlands and the National Institute for Health and Care Excellence from the United Kingdom.

Results

All ICHOM sets and HTAs used overall survival, whereas quality improvement used different survival estimates. Different progression estimates for cancer were used in HTAs, ICHOM sets, and quality improvement. Data on health-related quality of life (HRQoL) was recommended in all ICHOM sets and all HTAs, but selectively for quality improvement. In HTAs, generic HRQoL questionnaires were preferred, whereas, in quality improvement and ICHOM sets, disease-specific questionnaires were recommended. Unfavorable outcomes were included in all HTAs and all ICHOM sets, but not always for quality improvement.

Conclusions

Although HTA and quality improvement use outcome measures from the same domains, a greater level of alignment seems possible. ICHOM may provide input on standardized outcome measures to support this alignment. However, residual discrepancies will remain due to the different objectives of HTA and quality improvement.

Standardising the Assessment of Patient-reported Outcome Measures in Localised Prostate Cancer. A Systematic Review

CONTEXT

Prostate cancer (PCa) is the second most common cancer among men worldwide. Urinary, bowel, and sexual function, as well as hormonal symptoms and health-related quality of life (HRQoL), were prioritised by patients and professionals as part of a core outcome set for localised PCa regardless of treatment type.

OBJECTIVE

To systematically review the measurement properties of patient-reported outcome measures (PROMs) used in localised PCa and recommend PROMs for use in routine practice and research settings.

EVIDENCE ACQUISITION

The psychometric properties of PROMs measuring functional and HRQoL domains used in randomised controlled trials including patients with localised PCa were assessed according to the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology. MEDLINE and Embase were searched to identify publications evaluating psychometric properties of the PROMs. The characteristics and methodological quality of the studies included were extracted, tabulated, and assessed according to the COSMIN criteria.

EVIDENCE SYNTHESIS

Overall, 27 studies evaluating psychometric properties of the Expanded Prostate Cancer Index Composite (EPIC), University of California-Los Angeles Prostate Cancer Index (UCLA-PCI), European Organisation for Research and Treatment of Cancer (EORTC) quality of life core 30 (QLQ-C30) and prostate cancer 25 (QLQ-PR25) modules, International Index of Erectile Function (IIEF), and the 36-item (SF-36) and 12-item Short-Form health survey (SF-12) PROMs were identified and included in the systematic review. EPIC and EORTC QLQ-C30, a general module that assesses patients' physical, psychological, and social functions, were characterised by high internal consistency (Cronbach's α 0.46-0.96 and 0.68-0.94 respectively) but low content validity. EORTC QLQ-PR25, which is primarily designed to assess PCa-specific HRQoL, had moderate content validity and internal consistency (Cronbach's α 0.39-0.87). UCLA-PCI was characterised by moderate content validity and high internal consistency (Cronbach's α 0.21-0.94). However, it does not directly assess hormonal symptoms, whereas EORTC QLQ-PR25 does.

CONCLUSION

The tools with the best evidence for psychometric properties and feasibility for use in routine practice and research settings to assess PROMs in patients with localised PCa were EORTC QLQ-C30 and QLQ-PR25. Since EORTC QLQ-C30 is a general module that does not directly assess PCa-specific issues, it should be adopted in conjunction with the QLQ-PR25 module.

PATIENT SUMMARY

We reviewed and appraised the measurement properties of patient-reported outcome measure questionnaires used for patients with localised prostate cancer. We found good evidence to suggest that two questionnaires (EORTC QLQ-C30 and QLQ-PR25) can be used to measure urinary, bowel, and sexual functions and health-related quality of life.

Predictors for the utilization of social service counseling by prostate cancer patients

PURPOSE

Social service counseling (SSC) is an important instrument to support cancer patients, for example, regarding legal support, or rehabilitation. Several countries have established on-site SSC in routine care. Previous analyses have shown that SSC utilization varies across cancer centers. This analysis investigates patient and center-level predictors that explain variations in SSC utilization between centers.

METHODS

Logistic multilevel analysis was performed with data from 19,865 prostate cancer patients from 102 prostate cancer centers in Germany and Switzerland. Data was collected within an observational study between July 2016 and June 2020 using survey (online and paper) and tumor documentation.

RESULTS

The intraclass correlation coefficient for the null model implies that 51% of variance in SSC utilization is attributable to the center a patient is treated in. Patients aged 80 years and older, with higher education, private insurance, without comorbidities, localized intermediate risk, and undergoing androgen deprivation therapy before study inclusion were less likely to utilize SSC. Undergoing primary radiotherapy, active surveillance, or watchful waiting as compared to prostatectomy was associated with a lower likelihood of SSC utilization. Significant negative predictors at the center level were university hospital, center's location in Switzerland, and a short period of certification.

CONCLUSION

The results show that patient and center characteristics contribute to explaining the variance in SSC utilization in prostate cancer centers to a large extent. The findings may indicate different organizational processes in the countries included and barriers in the sectoral structure of the healthcare system. In-depth analyses of processes within cancer centers may provide further insights into the reasons for variance in SSC utilization.

Mapping the Patient-Oriented Prostate Utility Scale From the Expanded Prostate Cancer Index Composite and the Short-Form Health Surveys

OBJECTIVES

This study aimed to develop mapping algorithms from the Expanded Prostate Cancer Index Composite (EPIC) and the Short-Form (SF) Health Surveys to the Patient-Oriented Prostate Utility Scale (PORPUS), an econometric instrument specifically developed for patients with prostate cancer.

METHODS

Data were drawn from 2 cohorts concurrently administering PORPUS, EPIC-50, and SF-36v2. The development cohort included patients who had received a diagnosis of localized or locally advanced prostate cancer from 2017 to 2019. The validation cohort included men who had received a diagnosis of localized prostate cancer from 2014 to 2016. Linear regression models were constructed with ln(1 - PORPUS utility) as the dependent variable and scores from the original and brief versions of the EPIC and SF as independent variables. The predictive capacity of mapping models constructed with all possible combinations of these 2 instruments was assessed through the proportion of variance explained (R²) and the agreement between predicted and observed values. Validation was based on the comparison between estimated and observed utility values in the validation cohort.

RESULTS

Models constructed with EPIC-50 with and without SF yielded the highest predictive capacity (R² = 0.884, 0.871, and 0.842) in comparison with models constructed with EPIC-26 (R² = 0.844, 0.827, and 0.776). The intraclass correlation coefficient was excellent in the 4 models (>0.9) with EPIC and SF. In the validation cohort, predicted PORPUS utilities were slightly higher than those observed, but differences were not statistically significant.

CONCLUSIONS

Mapping algorithms from both the original and the abbreviated versions of the EPIC and the SF Health Surveys allow estimating PORPUS utilities for economic evaluations with cost-utility analyses in patients with prostate cancer.

The Key Role of Patient Involvement in the Development of Core Outcome Sets in Prostate Cancer

Patients are the stewards of their own care and hence their voice is important when designing and implementing research. Patients should be involved not only as participants in research that impacts their care, as the recipients of that care and any associated harms, but also as research collaborators in prioritising important questions from the patient perspective and designing the research and the ways in which is it most appropriate to involve patients. The PIONEER Consortium, an international multistakeholder collaboration lead by the European Association of Urology, has developed a core outcome set (COS) for localised and metastatic prostate cancer relevant to all stakeholders in particular patients. Throughout the work of PIONEER, patient representatives were involved as collaborators in setting the research agenda, and a wider group of patients was involved as participants in developing COSs, for instance in consensus meetings on choosing important outcomes and appropriate definitions. This publication showcases the process for COS development and highlights the most important recommendations to ultimately inform future research projects co-created between patients and other stakeholders. PATIENT SUMMARY: An important step in involving patients in the selection of outcomes for clinical trials, clinical audits, and real-world evidence is the development of a core outcome set (COS) that is relevant to all stakeholders. This report highlights the patient participation throughout our PIONEER COS development. TAKE HOME  MESSAGE: An important step in involving patients in the selection of outcomes for clinical trials, clinical audits, and real-world evidence is to develop a core outcome set (COS) that is relevant to all stakeholders. As part of the work of the PIONEER Consortium, we aim to highlight the patient participation throughout our PIONEER COS development.

Common patient-reported outcomes across ICHOM Standard Sets: the potential contribution of PROMIS®

BACKGROUND

The International Consortium for Health Outcomes Measurement (ICHOM) develops condition-specific Standard Sets of outcomes to be measured in clinical practice for value-based healthcare evaluation. Standard Sets are developed by different working groups, which is inefficient and may lead to inconsistencies in selected PROs and PROMs. We aimed to identify common PROs across ICHOM Standard Sets and examined to what extend these PROs can be measured with a generic set of PROMs: the Patient-Reported Outcomes Measurement Information System (PROMIS®).

METHODS

We extracted all PROs and recommended PROMs from 39 ICHOM Standard Sets. Similar PROs were categorized into unique PRO concepts. We examined which of these PRO concepts can be measured with PROMIS.

RESULTS

A total of 307 PROs were identified in 39 ICHOM Standard Sets and 114 unique PROMs are recommended for measuring these PROs. The 307 PROs could be categorized into 22 unique PRO concepts. More than half (17/22) of these PRO concepts (covering about 75% of the PROs and 75% of the PROMs) can be measured with a PROMIS measure.

CONCLUSION

Considerable overlap was found in PROs across ICHOM Standard Sets, and large differences in terminology used and PROMs recommended, even for the same PROs. We recommend a more universal and standardized approach to the selection of PROs and PROMs. Such an approach, focusing on a set of core PROs for all patients, measured with a system like PROMIS, may provide more opportunities for patient-centered care and facilitate the uptake of Standard Sets in clinical practice.
