Content validation of a self-report daily diary in patients with sickle cell disease

Daily Loneliness Affects Quality of Life in Sickle Cell Disease

BACKGROUND

Loneliness is related to psychosomatic challenges in chronic illnesses; however, very little research focuses on loneliness in sickle cell disease (SCD), the most common genetic blood disorder. This study used a daily diary method to illustrate how loneliness and quality of life co-occur in the day-to-day lives of people living with SCD.

METHOD

Seventy-nine adults living with SCD (63 women; mean age = 31.76 years) completed daily electronic surveys comprised of a brief loneliness scale and a single-item measure of quality of life. Participants completed each survey once per day for up to 42 consecutive days. We evaluated the effects of daily changes in loneliness on next-day quality of life through multilevel regression models.

RESULTS

Central findings indicated that there were significant between-person (b = - .993, p < .001, 95% CI = - 1.26, - .725) and within-person (b = - .202, p < .005, 95% CI = .327, - .089) effects. Specifically, participants who reported higher mean levels of loneliness also reported lower quality of life. Further, days on which participants reported higher loneliness were followed by days on which they reported lower quality of life.

CONCLUSIONS

These results may be the first to suggest a connection between loneliness and psychological outcomes in adults living with SCD. Daily fluctuations in loneliness appear to be associated with decrements in next-day quality of life. Future studies should elucidate the clinical relevance and broader health-related implications of these findings.

Systematic Review of the Effect of a One-Day Versus Seven-Day Recall Duration on Patient Reported Outcome Measures (PROMs)

BACKGROUND

There is ongoing uncertainty around the most suitable recall period for patient-reported outcome measures (PROMs).

METHOD

This systematic review integrates quantitative and qualitative literature across health, economics, and psychology to explore the effect of a one-day (or '24-h') versus seven-day (or 'one week') recall period. The following databases were searched from database inception to 30 November 2021: MEDLINE, EMBASE, PsycINFO, Web of Science, EconLit, CINAHL Complete, Cochrane Library, and Sociological Abstracts. Studies were included that compared a one-day (or '24-h') versus seven-day (or weekly) recall period condition on patient-reported scores for PROM and Health-Related Quality-of-Life (HRQoL) instrument scores in adult populations (aged 18 and above) or combined paediatric and adult populations with a majority of respondents aged over 18 years. Studies were excluded if they assessed health behaviours only, used ecological momentary assessment to derive an index of daily recall, or incorporated clinician reports of patient symptoms. We extracted results relevant to six domains with generic health relevance: physical functioning, pain, cognition, psychosocial wellbeing, sleep-related symptoms and aggregated disease-specific signs and symptoms. Quantitative studies compared weekly recall scores with the mean or maximum score over the last seven days or with the same-day recall score.

RESULTS

Overall, across the 24 quantitative studies identified, 158 unique results were identified. Symptoms tended to be reported as more severe and HRQoL lower when assessed with a weekly recall than a one-day recall. A narrative synthesis of 33 qualitative studies integrated patient perspectives on the suitability of a one-day versus seven-day recall period for assessing health state or quality of life. Participants had mixed preferences, some noted the accuracy of recall for the one-day period but others preferred the seven-day recall for conditions characterised by high symptom variability, or where PROMs concepts required integration of infrequent experiences or functioning over time.

CONCLUSION

This review identified a clear trend toward higher symptom scores and worse quality of life being reported for a seven-day compared to a one-day recall. The review also identified anomalies in this pattern for some wellbeing items and a need for further research on positively framed items. A better understanding of the impact of using different recall periods within PROMs and HRQoL instruments will help contextualise future comparisons between instruments. Questionnaires ask patients about their health over different time periods (e.g., "what were your symptoms like over the last week?" versus "what were your symptoms like today?"). Studies find that people may report their symptoms as more severe when they are asked to think about their symptoms over the last week compared to the last day. Understanding how different time periods influence patient responses will allow researchers to compare and develop new questionnaires and may help clinicians to choose the best questionnaire to understand their patient's condition. We conducted a systematic literature review on studies which had looked at the impact of using different recall periods on patient responses. We found 24 studies that compared patient scores from questionnaires asking their health "over the last day" compared to "over the last week". Overall, symptoms tended to be reported as more severe and health as poorer when they were reported over the last week compared to the last day on average. We also found 33 studies that asked patients to describe which recall period they preferred. Patients had mixed preferences with more preferring a seven-day recall where symptoms and health impacts varied a lot.

Detecting the Effect Size of Weather Conditions on Patient-Reported Outcome Measures (PROMs)

One of the next frontiers in medical research, particularly in orthopaedic surgery, is personalized treatment outcome prediction. In personalized medicine, treatment choices are adjusted for the patient based on the individual's and their disease's distinct features. A high-value and patient-centered health care system requires evaluating results that integrate the patient's viewpoint. Patient-reported outcome measures (PROMs) are widely used to shed light on patients' perceptions of their health status after an intervention by using validated questionnaires. The aim of this study is to examine whether meteorological or light (night vs. day) conditions affect PROM scores and hence indirectly affect health-related outcomes. We collected scores for PROMs from questionnaires completed by patients (N = 2326) who had undergone hip and knee interventions between June 2017 and May 2020 at the IRCCS Orthopaedic Institute Galeazzi (IOG), Milan, Italy. Nearest neighbour propensity score (PS) matching was applied to ensure the similarity of the groups tested under the different weather-related conditions. The exposure PS was derived through logistic regression. The data were analysed using statistical tests (Student's t-test and Mann-Whitney U test). According to Cohen's effect size, weather conditions may affect the scores for PROMs and, indirectly, health-related outcomes via influencing the relative humidity and weather-related conditions. The findings suggest avoiding PROMs' collection in certain conditions if the odds of outcome-based underperformance are to be minimized. This would ensure a balance between costs for PROMs' collection and data availability.
