Measuring Health Outcomes in HIV: Time to Bring in the Patient Experience

Development and validation of the patient-reported outcome for older people living with HIV/AIDS in China (PROHIV-OLD)

BACKGROUND

The involvement of quality of life as the UNAIDS fourth 90 target to monitor the global HIV response highlighted the development of patient-reported outcome (PRO) measures to help address the holistic needs of people living with HIV/AIDS (PLWHA) beyond viral suppression. This study developed and tested preliminary measurement properties of a new patient-reported outcome (PROHIV-OLD) measure designed specifically to capture influences of HIV on patients aged 50 and older in China.

METHODS

Ninety-three older people living with HIV/AIDS (PLWHA) were interviewed to solicit items and two rounds of patient cognitive interviews were conducted to modify the content and wording of the initial items. A validation study was then conducted to refine the initial instrument and evaluate measurement properties. Patients were recruited between February 2021 and November 2021, and followed six months later after the first investigation. Classical test theory (CTT) and item response theory (IRT) were used to select items using the baseline data. The follow-up data were used to evaluate the measurement properties of the final instrument.

RESULTS

A total of 600 patients were recruited at the baseline. Of the 485 patients who completed the follow-up investigation, 483 were included in the validation sample. The final scale of PROHIV-OLD contained 25 items describing five dimensions (physical symptoms, mental status, illness perception, family relationship, and treatment). All the PROHIV-OLD dimensions had satisfactory reliability with Cronbach's alpha coefficient, McDonald's ω, and composite reliability of each dimension being all higher than 0.85. Most dimensions met the test-retest reliability standard except for the physical symptoms dimension (ICC = 0.64). Confirmatory factor analysis supported the structural validity of the final scale, and the model fit index satisfied the criterion. The correlations between dimensions of PROHIV-OLD and MOS-HIV met hypotheses in general. Significant differences on scores of the PROHIV-OLD were found between demographic and clinical subgroups, supporting known-groups validity.

CONCLUSIONS

The PROHIV-OLD was found to have good feasibility, reliability and validity for evaluating health outcome of Chinese older PLWHA. Other measurement properties such as responsiveness and interpretability will be further examined.

Understanding clinical outcome measures reported in HIV pregnancy studies involving antiretroviral-naive and antiretroviral-experienced women

HIV infection is a clinically significant public health disease and contributes to increased risk of maternal and fetal morbidity and mortality. HIV pregnancy studies use outcome measures as metrics to show how people with HIV feel, function, or survive. These endpoints are crucial for tracking the evolution of HIV illness over time, assessing the effectiveness of antiretroviral therapy (ART), and comparing outcomes across studies. Although the need for ideal outcome measures is widely acknowledged, selecting acceptable outcome measures for these HIV pregnancy studies can be challenging. We discuss the many outcome measures that have been implemented over time to assess HIV in pregnancy studies, their benefits, and drawbacks. Finally, we offer suggestions for improving the reporting of outcome measures in HIV in pregnancy studies. Medical professionals can best care for pregnant women living with HIV receiving ART by having a thorough understanding of these outcome metrics.

Patient-Centered Core Impact Sets: What They are and Why We Need Them

A quote attributed to Mark Twain states, “What gets us into trouble is not what we don’t know. It’s what we know for sure that just ain’t so.” The growing focus on patient centricity has revealed a misalignment between what patients report as important to them about their disease and/or treatment, and the data collected in research and care. Decisions across healthcare are made using an evidence base most stakeholders acknowledge is inadequate. Patients might report that what is important to them are everyday life impacts, concepts that can be very different from the more typical clinical outcomes we often track. In this paper, we encourage expanding current thinking to all “impacts,” not only health outcomes, but also the other equally (and sometimes more important) concerns patients report as important to them. We propose that a patient-centered core impact set be developed for each disease or condition of interest, and/or subpopulation of patients. A patient-centered core impact set begins with gathering from patients and caregivers an inventory of all impacts disease and treatments have on a patient’s (and carers’ and families’) life. Then, through a formal prioritization process, a core set of impacts is derived, inclusive of but extending beyond relevant health outcomes. We offer several recommendations on how to move the goal of a patient-centered core impact set forward through collaboration, leadership, and establishment of a patient-centered core impact set development blueprint with supporting tools.

Psychometric properties of self-reported measures of health-related quality of life in people living with HIV: a systematic review

Objective

To identify and assess the psychometric properties of patient-reported outcome measures (PROMs) of health-related quality of life (HRQoL) in people living with HIV (PLWH).

Methods

Nine databases were searched from January 1996 to October 2020. Methodological quality was assessed by using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) Risk of Bias Checklist. We used the COSMIN criteria to summarize and rate the psychometric properties of each PROM. A modified Grading, Recommendations, Assessment, Development, and Evaluation (GRADE) system was used to assess the certainty of evidence.

Results

Sixty-nine studies reported on the psychometric properties of 30 identified instruments. All studies were considered to have adequate methodological quality in terms of content validity, construct validity, and internal consistency. Limited information was retrieved on cross-cultural validity, criterion validity, reliability, hypothesis testing, and responsiveness. High-quality evidence on psychometric properties was provided for the Medical Outcomes Study HIV Health Survey (MOS-HIV), the brief version of the World Health Organization's Quality of Life Instrument in HIV Infection (WHOQoL-HIV-BREF), 36-Item Short Form Survey (SF-36), Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQoL-HIV), and WHOQoL-HIV.

Conclusions

The findings from the included studies highlighted that among HIV-specific and generic HRQoL PROMs, MOS-HIV, WHOQoL-HIV-BREF, SF-36, MQoL-HIV, and WHOQoL-HIV are strongly recommended to evaluate HRQoL in PLWH in research and clinics based on the specific aims of assessments and the response burden for participants.

Development of the HIV360 international core set of outcome measures for adults living with HIV: A consensus process

OBJECTIVES

HIV outcomes centre primarily around clinical markers with limited focus on patient-reported outcomes. With a global trend towards capturing the outcomes that matter most to patients, there is agreement that standardizing the definition of value in HIV care is key to their incorporation. This study aims to address the lack of routine, standardized data in HIV care.

METHODS

An international working group (WG) of 37 experts and patients, and a steering group (SG) of 18 experts were convened from 14 countries. The project team (PT) identified outcomes by conducting a literature review, screening 1979 articles and reviewing the full texts of 547 of these articles. Semi-structured interviews and advisory groups were performed with the WG, SG and people living with HIV to add to the list of potentially relevant outcomes. The WG voted via a modified Delphi process - informed by six Zoom calls - to establish a core set of outcomes for use in clinical practice.

RESULTS

From 156 identified outcomes, consensus was reached to include three patient-reported outcomes, four clinician-reported measures and one administratively reported outcome; standardized measures were included. The WG also reached agreement to measure 22 risk-adjustment variables. This outcome set can be applied to any person living with HIV aged > 18 years.

CONCLUSIONS

Adoption of the HIV360 outcome set will enable healthcare providers to record, compare and integrate standardized metrics across treatment sites to drive quality improvement in HIV care.

Self-management: A comprehensive approach to improve quality of life among people living with HIV in Indonesia

Background

People living with HIV (PLWH) today have to deal with a chronic condition that requires efficient self-management due to increased longevity. Self-management interventions have been shown to improve physical and psychological symptoms as well as clinical results in chronic diseases. However, few studies have investigated the effect of self-management on quality of life (QOL) among PLWH in Indonesia.

Objective

To examine the effect of a self-management program on QOL among PLWH in Indonesia.

Methods

This was a quasi-experimental study with a comparison group in a general hospital in Jakarta, Indonesia. Of the 114 recruited PLWH, 57 were assigned to the intervention group and 57 to the comparison group. The self-management group attended a four-week program workshop. The intervention consisted of five sessions: need assessment and goal setting, maintaining a healthy lifestyle, educational participation to increase communication and self-esteem, and evaluation. The comparison group received standard educational material throughout the leaflet regarding HIV prevention. The post-test assessment was conducted immediately after intervention (T1) and two months (T2) after the intervention in both groups. QOL was measured using the World Health Organization Quality of Life (WHOQOL)-HIV brief Bahasa version. The estimations were obtained using fixed-effect regressions. The differences between T0, T1, and T2 for the intervention and comparison groups were evaluated and compared using the DI Differences method (DID).

Results

The self-management program improved outcomes relative to the comparison group at T1: 1) overall QOL score increased 8.7% (95% CI 0.021-0.149), 2) physical domain saw a modest increased 8.8% (95% CI 0.017-0.125), 3) psychological domain increased 23.5 % (95% CI 0.085-0.689), and 4) environmental domain showed a modest increase of 18.7% (95% CI 0.053-0.371). At T2, the total QOL score and the physical, psychological, and environmental dimensions were significantly improved compared to the comparison group.

Conclusion

The self-management program appears to improve the QOL of the life of PLWH. Nurses are advised to provide PLWH with self-management training. Future research on self-management intervention would need to be refined further to ensure that each community achieves consistent intervention outcomes.
