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.

A short intervention targeting psychosomatic care in older adults with complex health care needs-results of a randomized controlled trial.

OBJECTIVE: The aim of this randomized controlled trial (RCT) was to assess the efficacy of a short intervention targeting psychosomatic care in older adults with complex health care needs. METHODS: Participants were recruited in the frame of the 11-year follow-up of a large population-based study by means of the INTERMED interview. The INTERMED interview is an integrative assessment method to identify bio-psycho-social health care needs. Persons with high health care needs (interview score ≥ 17) were invited to take part. Participants were randomized with a 1:1 ratio to a control and an intervention group. The intervention group received a home visit conducted by a doctor trained in psychosomatic medicine. The primary hypothesis stated that the intervention group would have a better outcome with respect to health related quality of life (HRQOL) measured by the 12-item short-form health survey (mental component score, MCS) 6 months after randomization (T1). Secondary outcomes were physical HRQOL, health care needs, depression, anxiety, and somatic symptom severity. RESULTS: In total, 175 participants were included. At the three-year follow-up (T2), 97 participants (55.4%) were included. At T1, we did not find a difference regarding MCS between the intervention and control groups. At T2, the intervention group showed significantly lower health care needs compared with the control group. Regarding HRQOL, depression, and somatic symptom severity the two groups did not differ at T2. CONCLUSIONS: The primary hypothesis was not confirmed. However, results indicate that a short intervention with complex patients could lead to reduced bio-psycho-social health care needs.

Caring for the elderly: A person-centered segmentation approach for exploring the association between health care needs, mental health care use, and costs in Germany.

BACKGROUND: Person-centered care demands the evaluation of needs and preferences of the patients. In this study, we conducted a segmentation analysis of a large sample of older people based on their bio-psycho-social-needs and functioning. The aim of this study was to clarify differences in health care use and costs of the elderly in Germany. METHODS: Data was derived from the 8-year follow-up of the ESTHER study-a German epidemiological study of the elderly population. Trained medical doctors visited n = 3124 participants aged 57 to 84 years in their home. Bio-psycho-social health care needs were assessed using the INTERMED for the Elderly (IM-E) interview. Further information was measured using questionnaires or assessment scales (Barthel index, Patients Health Questionnaire (PHQ) etc.). The segmentation analysis applied a factor mixture model (FMM) that combined both a confirmatory factor analysis and a latent class analysis. RESULTS: In total, n = 3017 persons were included in the study. Results of the latent class analysis indicated that a five-cluster-model best fit the data. The largest cluster (48%) can be described as healthy, one cluster (13.9%) shows minor physical complaints and higher social support, while the third cluster (24.3%) includes persons with only a few physical and psychological difficulties ("minor physical and psychological complaints"). One of the profiles (10.5%) showed high and complex bio-psycho-social health care needs ("complex needs") while another profile (2.5%) can be labelled as "frail". Mean values of all psychosomatic variables-including the variable health care costs-gradually increased over the five clusters. Use of mental health care was comparatively low in the more burdened clusters. In the profiles "minor physical and psychological complaints" and "complex needs", only half of the persons suffering from a mental disorder were treated by a mental health professional; in the frail cluster, only a third of those with a depression or anxiety disorder received mental health care. CONCLUSIONS: The segmentation of the older people of this study sample led to five different clusters that vary profoundly regarding their bio-psycho-social needs. Results indicate that elderly persons with complex bio-psycho-social needs do not receive appropriate mental health care.

Association of hypertension with depression and generalized anxiety symptoms in a large population-based sample of older adults.

OBJECTIVE: The aim of the study was to assess the association of hypertension and symptoms of depression and generalized anxiety in a large cohort of elderly people. METHODS: Data were derived from the 8-year follow-up (2008-2010) of the epidemiological ESTHER-cohort study. A total of 3124 randomly chosen participants aged 57-84 were visited at their homes by trained study doctors. General practitioner based diagnosis, self-reported status of hypertension, medication, and blood pressure measurement were considered to define the existence of hypertension. Depression and general anxiety severity were assessed using validated questionnaires. Logistic regression analyses were performed to determine cross-sectional associations between hypertension and clinically significant symptoms of depression (CSD) and generalized anxiety. Well known lifestyle risk factors for hypertension such as obesity were included in multivariate cross-sectional analyses. RESULTS: Hypertension was prevalent in 1659 participants [53.1%; 95% confidence interval (CI) = (51.3; 54.9)]. CSD was detected in 163 participants [5.2%; 95%-CI = (4.4; 6.0)]. Symptoms of generalized anxiety were found in 434 participants [13.9%; 95%-CI = (12.7; 15.1)]. Patients with CSD showed significantly higher odds of being hypertensive [odds ratio (OR) = 1.76; 95%-CI = (1.14; 2.74)]. Participants with symptoms of generalized anxiety were found to have no higher odds for a hypertension diagnosis [OR = 1.1; 95%-CI = (0.85; 1.44)]. Overweight [OR = 1.86; 95%-CI = (1.53; 2.25)] as well as obesity [OR = 3.58; 95%-CI = (2.84; 4.52)] was significantly associated with hypertension. CONCLUSION: CSD appear to be related to hypertension in elderly adults. No association was found between symptoms of generalized anxiety and hypertension.

Measurement of skull bone thickness for bone-anchored hearing aids: an experimental study comparing both a novel ultrasound system (SonoPointer) and computed tomographic scanning to mechanical measurements.

HYPOTHESIS: A-mode ultrasound scanning with coded signals allows bone thickness measurements at the site of bone-anchored hearing aid surgery as compared to computed tomographic scanning and mechanical measurements. BACKGROUND: Adequate bone thickness is a prerequisite for successful, long-lasting osseointegration of titanium fixtures for bone-anchored hearing aids. Computed tomography can be used to measure bone thickness but has several drawbacks. MATERIAL: Bone thickness was measured at the site of bone-anchored hearing aids surgery in 28 formaldehyde-preserved human cadaver temporoparietal bones. Four blinded investigators used a hand-held, A-mode ultrasound system with direct coupling at 2.25 MHz transducer using coded signals (SonoPointer) and repeated the measurements twice. Comparisons were made with high-resolution computed tomographic scanning and mechanical micrometer caliper measurements. RESULTS: There was significant anatomical variation in the temporoparietal bones. Computed tomography was in good agreement with the mechanical reference. All specimens could be measured by the SonoPointer. The mean difference between the mechanical control and ultrasound scanning averaged for all measurements by all investigators was 0.3 mm (standard deviation, 1.2 mm). Trained ultrasound experts yielded better results (mean difference, 0.3 mm; standard deviation, 1.0 mm). Agreement was best for bone thickness up to 5 mm. Outliers occurred in bones thicker than 7.5 mm. CONCLUSION: The SonoPointer is a promising, noninvasive, hand-held tool for real-time measurement of bone thickness in bone-anchored hearing aid surgery, especially for children. Even disregarding the absolute thickness reading, the SonoPointer could be used to search intraoperatively for a local maximum of bone thickness.
