Personality, Healthcare Use and Costs-A Systematic Review

The relationship between personality traits and health-related quality of life after mild-to-moderate traumatic brain injury

BACKGROUND

Traumatic brain injury (TBI) causes major societal burden and may negatively influence an individual's health-related quality of life (HRQoL). Personality factors have been linked to persistent post-concussion symptoms (PPCS), and PPCS have been found to affect HRQoL. However, there is a knowledge gap concerning the association between personality traits and HRQoL after mild-to-moderate TBI. Thus, this study aims to investigate the association between personality traits and HRQoL in patients with mild-to-moderate TBI at 15 months post-injury, while controlling for socio-demographic characteristics, injury-related factors and symptom burden.

METHODS

Data from 86 participants with mild- to-moderate TBI from a previous randomised controlled trial were analysed. Sociodemographic, injury-related and psychological factors were recorded 2-3 months post-injury. Personality traits were measured at 15 months post-injury with The NEO Five-factor Inventory-3. The Quality of Life after Brain Injury- Overall Scale (QOLIBRI-OS) and the EuroQol-visual analogue scale (EQ-VAS) were used to measure HRQoL at 15 months post-injury. Two separate multiple linear regression models were performed for the outcome variables; QOLIBRI-OS (model 1) and EQ-VAS (model 2).

RESULTS

The factors associated with lower HRQoL were more severe PPCS, higher levels of the personality traits neuroticism and conscientiousness (model 1), female sex and being single/living alone (model 2). Higher levels of the personality trait extraversion were associated with higher HRQoL in both models.

CONCLUSION

The results highlight how non-injury factors may be associated with recovery and HRQoL after TBI. Considering personality factors may be helpful when identifying individual risk and protective factors for outcomes after mild-to-moderate TBI.

Determinants of the number of dental visits in the general adult population in Germany during the COVID-19 pandemic

BACKGROUND

Oral health is essential to general health and well-being. The utilization of oral health care services represents an important factor in reducing oral health morbidities. In order to understand the disparities in the frequency of dental visits, it is necessary to identify determinants that influence the use of those services. The aim of the current study was to investigate the determinants of the number of dental visits in Germany during the COVID-19 pandemic.

METHODS

We used data from the general adult population in Germany with n = 2,807 individuals in the analytical sample. Average age was 46.5 years (SD: 15.2 years, range 18 to 74 years) and 48.2% of the individuals were female. The number of dental visits in the preceding 12 months served as outcome measure. Grounded on the extended Andersen model, various determinants were included in regression analysis. Multiple negative binomial regressions were used.

RESULTS

Negative binomial regressions showed that a higher number of dental visits was significantly associated with personality-related (higher conscientiousness, IRR: 1.09, 95% CI: 1.03-1.15; higher neuroticism, IRR: 1.06, 95% CI: 1.00-1.12) and psychosocial factors (higher loneliness, IRR: 1.12, 95% CI: 1.02-1.22). In contrast, only very few predisposing characteristics, and none of the enabling resources and need factors were significantly associated with the outcome measure.

CONCLUSIONS

This study particularly emphasized the importance of personality-related factors and psychosocial factors (in terms of loneliness) for the number of dental visits during the pandemic. These factors, often overlooked in prior research, deserve further attention in upcoming studies dealing with the number of dental visits.

Determinants of Patient Use and Satisfaction With Synchronous Telemental Health Services During the COVID-19 Pandemic: Systematic Review

BACKGROUND

Several recent studies examined patient use and satisfaction with synchronous telemental health services in response to the widespread implementation during the COVID-19 pandemic. However, a systematic review of recent literature on the determinants of these outcomes is missing.

OBJECTIVE

The aim of this systematic review was to give an extensive overview of the literature on and highlight the influential determinants of patient use and satisfaction with synchronous telemental health services during the COVID-19 pandemic.

METHODS

This review satisfied the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and was registered in PROSPERO. Peer-reviewed, quantitative studies that observed the determinants of patient use or satisfaction with synchronous telemental health services during the COVID-19 pandemic were included. PubMed, PsycInfo, and Web of Science database searches were conducted in August 2022 for English and German language studies published from 2020 onward. Key steps were performed by 2 reviewers. Determinants were synthesized into major categories informed by the dimensions of the widely used and established Unified Theory of Acceptance and Use of Technology.

RESULTS

Of the 20 included studies, 10 studies examined determinants of patient use, 7 examined determinants of patient satisfaction, and 3 observed both outcomes. The quality of the studies was mainly good or fair. There was substantial heterogeneity in the study designs, methods, and findings. Sociodemographic characteristics and health-related determinants were mostly considered. Some of the major dimensions of the Unified Theory of Acceptance and Use of Technology were neglected in recent studies. Although most findings were mixed or nonsignificant, some indications for potential relationships were found (eg, for sex, age, and symptom severity).

CONCLUSIONS

The findings revealed potential target groups (eg, female and young patients with mild symptoms) for future postpandemic telemental health interventions. However, they also identified patient groups that were harder to reach (eg, older patients with severe symptoms); efforts may be beneficial to address such groups. Future quantitative and qualitative research is needed to secure and expand on recent findings, which could help improve services.

Personality Traits and Coping Strategies as Psychological Factors Associated with Health-Related Quality of Life in Highly Sensitive Persons

Sensory-Processing Sensitivity (SPS) is the reactivity to different stimuli that occurs in some people with sufficient intensity to cause interference in daily life. There are not many previous studies that determine the influence of adaptive and maladaptive coping strategies on health-related quality of life through indicators of mental (anxiety and depression) and physical (vitality) health and functioning in their lives in different contexts (emotional role functioning). In this sense, contexts that promote the use of successful stress-coping strategies are related to the presence of positive mental health outcomes. This study focuses on the analysis of indicators of health-related quality of life in people with SPS in relation to certain personality traits and coping strategies. Participants (N = 10,525) completed HSPS-S, NEO-FFI, CSI, and SF-36. Differences were observed between men and women. Differences indicated that women had higher SPS scores compared to men and poorer health-related quality of life. The results showed significant relationships with the three indicators of health-related quality of life. Finally, it is confirmed that neuroticism and the use of maladaptive coping strategies act as risk factors, whereas extraversion, conscientiousness, and adaptive coping strategies act as protective factors. These findings highlight the need to develop prevention programs for highly sensitive persons.

Association Between Neuroticism and Dementia on Healthcare Use: A Multi-Level Analysis Across 27 Countries from The Survey of Health, Ageing and Retirement in Europe (SHARE)

BACKGROUND

People with high levels of neuroticism are greater users of health services. Similarly, people with dementia have a higher risk of hospitalization and medical visits. As a result, dementia and a high level of neuroticism increase healthcare use (HCU). However, how these joint factors impact the HCU at the population level is unknown. Similarly, no previous study has assessed the degree of generalization of such impacts, considering relevant variables including age, gender, socioeconomic, and country-level variability.

OBJECTIVE

To examine how neuroticism and dementia interact in the HCU.

METHODS

A cross-sectional study was performed on a sample of 76,561 people (2.4% with dementia) from 27 European countries and Israel. Data were analyzed with six steps multilevel non-binomial regression modeling, a statistical method that accounts for correlation in the data taken within the same participant.

RESULTS

Both dementia (Incidence Rate Ratio (IRR): 1.537; α= 0.000) and neuroticism (IRR: 1.122; α= 0.000) increased the HCU. The effect of having dementia and the level of neuroticism increased the HCU: around 53.67% for the case of having dementia, and 12.05% for each increment in the level of neuroticism. Conversely, high levels of neuroticism in dementia decreased HCU (IRR: 0.962; α= 0.073). These results remained robust when controlling for age, gender, socioeconomic, and country-levels effects.

CONCLUSION

Contrary to previous findings, neuroticism trait in people with dementia decreases the HCU across sociodemographic, socioeconomic, and country heterogeneity. These results, which take into account this personality trait among people with dementia, are relevant for the planning of health and social services.

Recovery from chronic depression and structural change: 5-year outcomes after psychoanalytic and cognitive-behavioural long-term treatments (LAC depression study)

OBJECTIVE

Psychotherapy of chronic depression has remained a challenge due to limited prognosis and high rates of recurrence. We present 5-year outcome data from a multicentre trial comparing psychoanalytic (PAT) and cognitive-behavioural (CBT) long-term treatments with randomized and preferred allocations analysing symptom (N = 227) and structural change (N = 134) trajectories.

METHOD

Self- and blinded expert ratings of depression symptoms were performed at yearly intervals using the Beck Depression Inventory-II (BDI-II) and Quick Inventory of Depressive Symptoms (QIDS-C). Blinded expert ratings of Operationalized Psychodynamic Diagnosis (OPD) and the Heidelberg Restructuring Scale (HRS) at baseline, 1, 3, and 5 years assessed structural change in a subsample.

RESULTS

Lasting and comparable symptom changes were achieved by PAT and CBT. However, compared to CBT, PAT was more successful in restructuring, a major goal of long-term psychodynamic treatments with high frequency and duration.

LIMITATIONS

Due to practical reasons, the time criterion for chronic depression of an acute phase had to be defined for over 1 year in the present study, which does not correspond to the DSM-5 criterion of 2 years. Therapy duration and session frequency were not incorporated into the statistical models.

CONCLUSION

Long-term psychotherapy helps patients with a yearlong history of depression and often multiple unsuccessful treatment attempts to achieve lasting symptom changes. Future follow-up will clarify whether restructuring promotes further sustainable improvements.

The Role of Country-Level Availability and Generosity of Healthcare Services, and Old-Age Ageism for Missed Healthcare during the COVID-19 Pandemic Control Measures in Europe

Objectives: The effects of the COVID-19 outbreak on non-COVID-19-related healthcare need further investigation. Methods: Using the Survey of Health, Ageing and Retirement in Europe's COVID-19 module (2020) (N = 57,025), country-level data from the European Social Survey (2008) and OECD (2020), and logistic regressions, this study examines predictors of older Europeans' forgone, postponed, and denied healthcare during the pandemic. Results: Country-level availability of physicians, healthcare systems' generosity, and beliefs that older persons burden healthcare systems all increased forgone healthcare. Healthcare system generosity increased postponed and denied healthcare. Greater medical resources decreased denied healthcare. Furthermore, missed healthcare varied by individual-level gender (higher rates among women), age, education, and health. Discussion: This study reveals predictors of missed healthcare during the pandemic. To decrease unintended health consequences of a pandemic, both individual-level determinants, such as gender and health, and contextual-level determinants, such as healthcare systems' characteristics, should be considered in research and practice.

The impact of the level of anxiety and temperament in asymptomatic or mildly symptomatic patients requesting implant removal surgery after tibia intramedullary nailing

BACKROUND

Implant removal (IR) surgery is one of the most frequent procedures in orthopedic practice. Many of the IR surgeries result from patient request rather than a medical necessity. The purpose of the study was to investigate the association between the level of anxiety, type of temperament and psychopathological status, and the willingness to receive IR surgery in asymptomatic or mildly symptomatic patients. We also aimed to compare pre- and postoperative pain scores and document the complication rates after IR surgery.

METHODS

The patients who received tibia intramedullary nailing after tibia diaphyseal fracture with a minimum of 18 months follow-up were included in the study. A total of 246 asymptomatic or mildly symptomatic patients were evaluated, and all patients received detailed oral and written information about the risks of IR surgery. The patients who wished to receive IR surgery were called Group 1 (N = 104), and the patients who did not wish to have surgery were called Group 2 (N = 146). All patients were referred to a psychologist to complete the Beck anxiety inventory (BAI), Symptom checklist-90-R (SCL-R-90), and the Temperament Evaluation of Memphis, Pisa, and San Diego Autoquestionnaire (TEMPS-A).

RESULTS

The mean age of the patients was 32.31 ± 9.56. One hundred thirteen (45.9%) of the patients were male, and 133 were female (54%). Mean BAI and SCL-90-R were higher in Group 1 than Group 2 (P = 0.001). Anxious and irritable temperament was higher in Group 1 (P = 0.045 and P = 0.035 respectively), and non-dominant and hyperthymic temperament was higher in Group 2 (P = 0.02 and P = 0.04 respectively).

CONCLUSIONS

The level of anxiety and type of temperament is associated with the willingness to receive implant removal surgery in asymptomatic or mildly symptomatic patients. Measures to reduce anxiety levels may reduce the rate of unnecessary implant removal surgeries, associated patient care costs, and potential complications.

Association between purpose in life and healthcare use among women and men in Germany: cross-sectional analysis of the nationally representative German Socio-Economic Panel (GSOEP) study

OBJECTIVES

It remains almost unknown whether purpose in life is associated with healthcare use (HCU) in general. Therefore, the goal of this study was to examine the association between purpose in life and HCU (in terms of frequency of outpatient physician visits and hospitalisation) stratified by sex.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

A representative sample of the general adult population in Germany (n=1238; collected from September 2020 to February 2021); taken from the innovation sample of the German Socio-Economic Panel.

OUTCOME MEASURES

The frequency of outpatient physician visits in the past 3 months was used as first outcome measure. Hospitalisation in the last 12 months was used as the second outcome measure. Purpose in life was quantified by means of the subscale 'purpose in life' of the six-factor model of psychological well-being. Covariates were selected based on the Andersen model.

RESULTS

Average purpose in life equaled 4.5 (SD: 0.8; ranging on a scale from 1 to 6, with higher values indicating higher purpose in life). Adjusting for various potential confounders, regressions revealed that higher purpose in life was associated with an increased frequency of outpatient physician visits in the past 3 months among women (IRR 1.16, 95% CI:1.03 to 1.30), but not men (IRR 0.96, 95% CI 0.87 to 1.07). In contrast, higher purpose in life was associated with in an increased likelihood of hospitalisation among men (OR 1.40, 95% CI 1.02 to 1.93), but not women (OR 1.03, 95% CI 0.79 to 1.34).

CONCLUSION

Even after adjusting for various potential confounders, there was still a gender-specific association between higher purpose in life and increased HCU. This knowledge may assist in addressing individuals at risk for underuse or overuse of healthcare services.

Factors Contributing to Persistent Frequent Attendance in Primary Care Among the Oldest Old: Longitudinal Evidence From the AgeCoDe-AgeQualiDe Study

Objective

Since there is a lack of longitudinal studies in this area, our aim was to identify the determinants of persistent frequent attendance in primary care among the oldest old in Germany.

Methods

Longitudinal data (follow-up wave 7-9) were taken from the multicenter prospective cohort "Study on needs, health service use, costs, and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe), covering primary care patients ≥ 85 years (FU7 n = 741, mean age 88.9 years (SD 2.9; 85-100)). Persistent frequent attenders of general practitioner (GP) services (the patients in the top decile of the number of GP consultations in two or more consecutive waves) were our main outcome of interest. Logistic random-effects models were used.

Results

Our analysis included 1,891 observations (766 individuals). Across three waves, we identified 56 persistent frequent attenders. Results of random-effects logistic regressions showed that the odds of being persistent frequent attender were higher for widowed individuals (OR = 4.57; 95% CI [1.07-19.45]). Moreover, a one-point increase in the frailty score and having one more chronic condition increased the odds of being a persistent frequent attender by 68% (OR =1.68; 95% CI [1.05-2.69]) and 23% (OR=1.23, 95% CI [1.05-1.44]), respectively.

Conclusion

Our study stressed the longitudinal association between frailty and widowhood as well as chronic diseases and persistent frequent attendance among the oldest old in Germany.

On the Relative Importance of Different Factors Explaining Health Plan Choices: Evidence From Mandatory Health Insurance in Switzerland

Many factors influence health plan choices. Classical individual-level determinants include socioeconomic and health-related characteristics, and risk attitudes. However, little is known to what extent personality traits can determine insurance choices. Using representative survey data from Switzerland, we investigate the associations between choices of health plans and traditional individual factors as well as personality traits. We employ dominance analysis to explore the relative importance of the different predictors. We find that personality traits play an at least equally important role in predicting health plan choices as common factors like age, health status, and income. Our results have implications regarding recent efforts to empower people in making better health plan choices and support theoretical models that integrate insights from behavioral sciences.

Determinants of health care use among homeless individuals: evidence from the Hamburg survey of homeless individuals

BACKGROUND

To identify the determinants of health care use among homeless individuals.

METHODS

Data were taken from the Hamburg survey of homeless individuals (n = 100 individuals in the here used model, mean age 44.8 years, SD 12.5) focusing on homeless individuals in Hamburg, Germany. The number of physician visits in the past 3 months and hospitalization in the preceding 12 months were used as outcome measures. Drawing on the Andersen model of health care use as a conceptual framework, predisposing characteristics, enabling resources and need factors as well as psychosocial variables were included as correlates.

RESULTS

Negative binomial regressions showed that increased physician visits were associated with being female (IRR: 4.02 [95% CI: 1.60-10.11]), absence of chronic alcohol consume (IRR: 0.26 [95% CI: 0.12-0.57]) and lower health-related quality of life (IRR: 0.97 [95% CI: 0.96-0.98]). Furthermore, logistic regressions showed that the likelihood of hospitalization was positively associated with lower age (OR: 0.93 [95% CI: 0.89-0.98]), having health insurance (OR: 8.11 [2.11-30.80]) and lower health-related quality of life (OR: 0.97 [95% CI: 0.94-0.99]).

CONCLUSIONS

Our study showed that predisposing characteristics (both age and sex), enabling resources (i.e., health insurance) and need factors in terms of health-related quality of life are main drivers of health care use among homeless individuals. This knowledge may assist in managing health care use.

Determinants of Frequent Attendance in Primary Care. A Systematic Review of Longitudinal Studies

Introduction: There is a lack of a systematic review synthesizing longitudinal studies investigating the determinants of frequent attendance in primary care. The goal of our systematic review was to fill this gap in knowledge.

Methods: Three electronic databases (Medline, PsycINFO, and CINAHL) were searched. Longitudinal observational studies analyzing the predictors of frequent attendance in primary care were included. Data extraction covered methods, sample characteristics, and main findings. Selection of the studies, extracting the data and evaluation of study quality was performed by two reviewers. In the results section, the determinants of frequent attendance were presented based on the (extended) Andersen model.

Results: In total, 11 longitudinal studies have been included in our systematic review. The majority of studies showed that frequent attendance was positively associated with the predisposing characteristics lower age, and unemployment. Moreover, it was mainly not associated with enabling resources. Most of the studies showed that need factors, and in particular worse self-rated health, lower physical functioning and physical illnesses were associated with an increased likelihood of frequent attendance. While most studies were of good quality, several of the included studies did not perform sensitivity analysis or described how they dealt with missing data.

Discussion: Our systematic review showed that particularly lower age, unemployment and need factors are associated with the likelihood of becoming a frequent attender. Enabling resources are mainly not associated with the outcome measure. Future research should concentrate on the determinants of persistent frequent attendance due to the high economic burden associated with it.
