AI Article Synopsis

  • A recent systematic review and meta-analysis showed that palliative care doesn't improve quality of life (QOL) for patients with terminal noncancer illnesses, leading to questions about the measures used to evaluate QOL in these populations.
  • The review specifically examined whether patient-reported outcome measures (PROMs) for QOL had been derived or validated in adults with advanced life-limiting illnesses, finding that only 47% of the 15 PROMs studied were linked to these populations.
  • The majority of these PROMs were validated primarily among cancer patients, suggesting that the current tools for measuring QOL in palliative care may not be appropriate for noncancer terminal illnesses, which could affect the interpretation of findings in related research.

Article Abstract

A recent systematic review and meta-analysis found that palliative care was not associated with improvement in quality of life (QOL) in terminal noncancer illness. Among potential reasons for a null effect, it is unclear if patient-reported outcome measures (PROMs) measuring QOL were derived or validated among populations with advanced life-limiting illness (ALLI). To systematically review the derivation and validation of QOL PROMs from a recent meta-analysis of randomized controlled trials (RCT) of palliative care interventions in people with terminal noncancer illness. EMBASE, MEDLINE, and PsycINFO were searched from inception to January 8, 2023 for primary validation studies of QOL PROMs in populations with ALLI, defined as adults with a progressive terminal condition and an estimated median survival of less than or equal to one year. The primary outcome was the proportion of PROMs that were derived or validated in ≥1 ALLI population. Twenty-one unique studies of derivation ( = 13) and validation ( = 11, 3 studies evaluated both) provided data on 9657 participants (mean age 63 years, 50% female) across 15 unique QOL PROMs and subscales. Among studies of validation, 9 were in people with cancer ( = 2289,  = 5 PROMs), 1 in neurodegenerative disease ( = 23,  = 1 PROM), and 1 with mixed diseases ( = 248,  = 1 PROM). Across 15 QOL PROMs and subscales, 47% ( = 7) were derived or validated in an ALLI population. The majority of these seven PROMs were exclusively derived or validated among people with cancer (57%,  = 4). QOL PROMs such as Quality of Life at End of Life, EuroQoL-5 Dimension 5-level, and 36-item Short Form Survey demonstrated validity in more than one terminal noncancer illness. Most QOL PROMs that measured the effect of palliative care on QOL in RCTs were neither derived nor validated in an ALLI population. These findings raise questions about the inferences that palliative care does not improve QOL among people with terminal noncancer illness.

Introduction: The minimal clinically important difference (MCID), patient-acceptable symptom state (PASS), and substantial clinical benefit (SCB) are designed to prioritise clinically significant outcomes that demonstrate true clinical benefit rather than relying solely on statistical significance. These instruments aid clinicians in understanding the patient's perspective, allowing healthcare professionals to set treatment goals that align with patients' desires and expectations. This systematic review analysed tools to estimate the clinical relevance of the most commonly used PROMs to assess patients following surgical knee ligament reconstruction.

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.

Dry eye disease (DED) is a multifactorial, chronic, and often relapsing condition with a significant impact on patient quality of life (QoL). Symptoms such as ocular discomfort and visual disturbances are diverse and frequently misaligned with objective clinical signs, complicating diagnosis and management. DED not only interferes with daily activities like reading, driving, and computer use but also imposes a substantial economic burden due to direct healthcare costs and reduced work productivity.

Sphenoid wing meningiomas (SWM) frequently compress structures of the optic pathway, resulting in significant visual dysfunction characterized by vision loss and visual field deficits, which profoundly impact patients' quality of life (QoL), daily activities, and independence. The objective of this study was to assess the impact of SWM surgery on patient-reported outcome measures (PROMs) regarding postoperative visual function. The Visual Function Score Questionnaire (VFQ-25) is a validated tool designed to assess the impact of visual impairment on quality of life.

Background: Evidence-based medicine and patient-reported outcome measures (PROMs) are helpful tools in the wound care field, but few studies correlating quality of life (QoL) changes with objective changes exist.

Objective: To investigate the QoL changes following the shift from primary dressings alone to elastic compression bandages in patients with a new diagnosis of vascular skin ulcer, and to evaluate a possible correlation between objective and subjective changes.

Materials And Methods: This study included 122 patients with a new diagnosis of vascular skin ulcer, who had previously used only primary dressings alone.
