Longitudinal association between panic disorder and health care costs in older adults.

BACKGROUND: To analyze whether probable panic disorder (PD) is associated with health care costs in older age over time. METHODS: Data regarding individuals aged 65 and over were derived from two waves of the ESTHER cohort study (nt1 = 2,348, nt2 = 2,090). Probable PD was assessed using the panic screening module from the Patient Health Questionnaire. Health care costs were obtained through monetary valuation of self-reported health care use data. Fixed effects regressions analyzed the association between transitions in probable PD status and change in health care costs, while adjusting for potential confounders. RESULTS: On a descriptive level, study participants with a positive PD screening displayed higher three-month health care costs compared to those without (incremental costs: € 259 for t1 , € 1,544 for t2 ). Transitions in probable PD were associated with an approximate increase of 65% in outpatient health care costs (ß = 0.50, p < .05). There was no significant association between probable PD transition and change in any other cost category. CONCLUSIONS: Using longitudinal data, our results highlight the economic consequences of probable PD in older adults. Future research should address whether reducing PD in older adults may reduce the associated economic burden and analyze underlying mechanisms.

Association of anxiety symptoms with health care use and costs in people aged 85 and over.

OBJECTIVE: To analyze the association of anxiety symptoms with health care use and costs in people aged 85 and older. METHODS: Baseline data from AgeQualiDe (N = 856), a multicenter prospective cohort study of primary care patients aged 85 and older, were analyzed. Anxiety symptoms (Geriatric Anxiety Inventory-Short Form) and health care use were assessed via questionnaires. Health care use was monetarily valued using German unit costs to obtain sectoral (inpatient, outpatient, nursing care, medical supplies, and medication) and total costs. Health care use and costs were analyzed in regression models as a function of anxiety symptoms, as well as relevant covariates (predisposing, enabling, and other need characteristics based on the Behavioral Model of Health Care Use). RESULTS: On a descriptive level, people with increased anxiety symptoms (12% of the sample) incurred on average € 10 909 (SD: 16 023) in the last 6 months, 31% more than those without increased anxiety (€ 8303, SD: 11 175; P = 0.12). Adjusting for predisposing, enabling, and other need characteristics, anxiety symptoms were not significantly associated with health care use or costs. Specifically, need characteristics (morbidity, cognitive decline, and functional impairment) were associated with total or sectoral costs, depending on the cost category analyzed. CONCLUSION: In a sample of people of the oldest-old age group, the severity of anxiety symptoms was not associated with health care use or costs, when adjusting for relevant covariates. A longitudinal analysis could assess whether a change in anxiety symptom severity is associated with health care use or costs in old age.

A systematic review of the association of anxiety with health care utilization and costs in people aged 65 years and older.

THEORETICAL BACKGROUND: In older people, anxiety disorders are among the most prevalent mental disorders and a high proportion suffers from clinically relevant anxiety symptoms. Despite studies suggesting an association of anxiety with health care utilization (HCU) and a resulting economic burden to the health care system, we found no review systematically analyzing evidence on this association in older people. OBJECTIVE: To analyze and synthesize evidence on the association of anxiety disorders and symptoms with HCU and costs in people aged 65 years and over in a systematic review. METHODS: A systematic search of peer-reviewed literature was conducted in three electronic databases. Additional references were identified through reference lists of included studies. Inclusion criteria were: studies reporting the association of anxiety disorders or symptoms with HCU or costs, specifically in people aged 65 years and over, with observational study design, in German or English language. Findings were synthesized qualitatively and study quality was assessed. RESULTS: N = 15 studies (HCU n = 10, costs n = 5) were included in the final synthesis. Overall, studies either reported significantly increased HCU in anxiety disorders compared to a healthy comparison group/according to degree of symptoms, or found no significant association between these variables. Total excess costs for anxiety disorders ranged from -116 to 19,003 $PPP per year. LIMITATIONS: Differences in methodology limited the comparability of included studies. CONCLUSION: Most studies suggest an increased economic burden due to anxiety in older people. Studies using standardized instruments are needed.
