Anxiety enhances the detrimental effect of depressive symptoms on health status following percutaneous coronary intervention.

OBJECTIVE: We examined whether anxiety has incremental value to depressive symptoms in predicting health status in patients undergoing percutaneous coronary intervention (PCI) treated in the drug-eluting stent era. METHODS: A series of consecutive patients (n=692) undergoing PCI as part of the Rapamycin-Eluting Stent Evaluated at Rotterdam Cardiology Hospital registry completed the Hospital Anxiety and Depression Scale at 6 months and the Short-Form Health Survey (SF-36) at 6 and 12 months post-PCI. RESULTS: Of 692 patients, 471 (68.1%) had no symptoms of anxiety nor depression, 62 (9.0%) had anxiety only, 59 (8.5%) had depressive symptoms only, and 100 (14.5%) had co-occurring symptoms. There was an overall significant improvement in health status between 6 and 12 months post-PCI (P<.001); the interaction effect for time by psychological symptoms was also significant (P=.003). Generally, patients with co-occurring symptoms reported significantly poorer health status compared with the other three groups (Ps <.001). Patients with co-occurring symptomatology were also at greater risk of impaired health status on six of the eight subdomains of the SF-36 compared with the other three symptom groups, adjusting for baseline characteristics and health status at 6 months. CONCLUSION: Patients with co-occurring symptoms of anxiety and depression reported poorer health status compared with anxious or depressed-only patients and no-symptom patients, showing that anxiety has incremental value to depressive symptoms in identifying PCI patients at risk for impaired health status treated in the drug-eluting stent era.

Health status measurement. Implementation strategies.

The creation of valid instruments of health status measurement does not guarantee their use in the clinical setting. Traditional continuing medical education has not been shown to effect physician behavioral change. Examination of the literature on the dissemination of new technology underscores the need for the acceptance and use of new methods by local opinion leaders whose behavior serves as a model for their colleagues. Since health status measurement will require a new way of evaluating the patient visit and the creation of new provider behaviors, widespread implementation will require the recruitment of local clinical leaders to serve as spokesmen for reconsideration of office care procedures. Advocates of health status measurement should seize on a variety of opportunities to disseminate their work. Medical school curricula in courses such as physical diagnosis could expose different approaches to the patient encounter to a new generation of physicians in a fairly painless and seamless manner. Academic practice plans, by virtue of their increasing trend to centralization, could commit to patient-oriented data collection--if not for instructional purposes, then for the overall health of the delivery system. The instruction of nurses and paraprofessionals in the collection of these data could expand the measures and help drive the system when physicians are not embracing the technology. There is need to exploit the enhanced capacity of computer hardware and software in the service of efficient data collection and trend analysis of health status.(ABSTRACT TRUNCATED AT 250 WORDS)

The impact of pediatric tracheotomy on parental caregiver burden and health status.

OBJECTIVE: To explore the effects of the placement of a pediatric tracheotomy tube on the degree of caregiver burden and overall health status of parents using general and disease-specific instruments. METHODS: Between January and July 2001, the Medical Outcomes Study Short Form 12 (SF-12) and the Pediatric Tracheotomy Health Status Instrument (PTHSI) were administered to 154 families of children requiring tracheotomy. Summary scores were generated for each of the 2 scales of the SF-12 (the Physical Component Score [PCS] and the Mental Component Score [MCS]) as well as for the 4 previously established domains of the PTHSI: domain 1, physical symptoms of the child (7 items); domain 2, medical visits and cost (7 items); domain 3, parental rating of the child's psychological health status (3 items); and domain 4, parental rating of their own caregiver burden (17 items). Correlations between responses from the individual domains and between domain 4 of the PTHSI (reflecting caregiver burden) and the SF-12 were performed. RESULTS: The mean +/- SD summary scores for the 4 domains of the PTHSI were domain 1, 22.7 +/- 5.3; domain 2, 24.9 +/- 6.2; domain 3, 10.5 +/- 4.4; and domain 4, 48.3 +/- 9.5 (lower scores reflect "poorer" health status). The mean +/- SD summary scores of PCS and MCS were 50.5 +/- 11.3 and 35.8 +/- 11.4, respectively. There existed a significant correlation between parental caregiver burden (as expressed by domain 4) and the child's physical health status (domain 1) (0.32; P<.001) as well as between parental caregiver burden and increasing economic costs associated with this care (0.27; P<.001). A strong correlation was found between the domain measuring parental caregiver burden (domain 4) and the MCS-12 (r = 0.43; P<.001), while a poor correlation existed with the PCS-12 (r = -0.17; P =.14). Nevertheless, in contrast to caregiver burden, the health status of the caregivers as measured by the SF-12 did not alter according to the severity of illness for the children (P =.17). CONCLUSIONS: Parents caring for children with tracheotomy tubes experience significant caregiver burden. These parents appear to experience increased burden with respect to the child's severity of illness and increased costs associated with caring for their children. Overall, the mental health status for an adult caring for a child with a tracheotomy tube is significantly reduced and appears to be more affected than physical health status.

Health status and heterogeneity of cost-sharing responsiveness: how do sick people respond to cost-sharing?

This paper examines whether the responsiveness of health care utilization to cost-sharing varies by health status and the implications of such heterogeneity. First, we show theoretically that if health care utilization of those in poor health is less responsive to cost sharing, this, combined with the skewness of health expenditures in health status, leads to overestimates of the effect of cost sharing. This bias is exacerbated when elasticities are generalized to populations with greater expenditure skewness. Second, we show empirically that cost-sharing responsiveness does differ by health status using data from the Medicare Current Beneficiary Survey. Medicare beneficiaries are stratified into health status groups based on activity of daily living (ADL) impairments and self-reported health status. Separately, for each of the health status groups, we estimate the effect of Medigap insurance on Part B utilization using a two-part expenditure model. We find that the change in expenditures associated with Medigap is smaller for those in poorer health. For example, when stratified using ADLs, Medigap insurance increases expenditures for 'healthy' groups by 36.4%, while the increase for the 'sick' group is 12.7%. Results are qualitatively the same for different forms of supplemental insurance and different methods of health status stratification. We develop a test to demonstrate that adjusting our results for selection bias would result in estimates of greater heterogeneity. Our results imply that a lowerbound estimate of the bias from neglecting heterogeneity is about 2-7%.

Regional variations in health status.

CONTEXT: Knowledge about variations in the health status of patients seeking primary care in different parts of the United States is limited. OBJECTIVE: To examine regional variations in the physical and mental health of patients receiving primary care in the largest integrated health care system in the United States which is operated by the Department of Veteran Affairs (VA). STUDY DESIGN AND SETTING: We performed a mailed, cross sectional survey of 54,844 patients who were enrolled in seven VA General Internal Medicine clinics. RESULTS: Among the 30,690 patients who returned an initial set of screening questionnaires, the prevalence of common chronic conditions varied by as much as 60% among the seven clinics. Moreover, patients' general health (measured by the SF-36) also varied significantly in a pattern that mirrored the observed differences in the prevalence of chronic conditions. After adjustment for important comorbid illnesses and sociodemographic factors, geographic site accounted for a small percentage of the explained variance in patient assessed health status. CONCLUSIONS: The substantial differences in the health of patients enrolled in different VA primary clinics have important implications for the evaluation of clinical performance and health outcomes. Most of these differences can be attributed to sociodemographic and comorbid factors.

Performance of health status measures with a pen based personal digital assistant.

BACKGROUND: Increasing use of self reported health status in clinical practice and research, as well as patient appreciation of monitoring fluctuations of health over time, suggest a need for more frequent collection of data. Electronic use of health status measures in the follow up of patients is a possible way to achieve this. OBJECTIVE: To compare self reported health status measures in a personal digital assistant (PDA) version and a paper/pencil version for test-retest reliability, agreement between scores, and feasibility. METHODS: 30 patients with stable rheumatoid arthritis (mean age 61.6 years, range 49.8 to 70.0; mean disease duration, 16.7 years; 63% female; 67% rheumatoid factor positive; 46.6% on disease modifying antirheumatic drugs) completed self reported health status measures (pain, fatigue, and global health on visual analogue scales (VAS), rheumatoid arthritis disease activity index, modified health assessment questionnaire, SF-36) in a conventional paper based questionnaire version and on a PDA (HP iPAQ, model h5450). Completion was repeated after five to seven days. RESULTS: Test-retest reliability was similar, as evaluated by the Bland-Altman approach, the coefficient of variation, and intraclass correlation coefficients. The scores showed acceptable agreement, but with a slight tendency to higher scores on VAS with the PDA than the paper/pencil version. No significant differences were seen for measures of feasibility (time to complete, satisfaction score), but 65.5% preferred PDA, 20.7% preferred paper, and 13.8% had no preference. CONCLUSIONS: The clinimetric performance of paper/pencil versions of self reported health status measures was similar to an electronic version, using an inexpensive PDA.

An empirical analysis of the dimensions of health status measures.

The objective of this study is to verify empirically the existence of separate dimensions in the overall concept of health status by analyzing 10 variables included in a questionnaire that was applied to all adults in a simple random sample of households in St John's, Newfoundland. The response rate was 85% for a total of 3300 subjects. These data were analyzed by frequencies and by associations with sex, age and education. Nonparametric correlation, factor and cluster analyses on variables were used to verify if health status had identifiable dimensions. All these methods produced similar results showing five distinct factors. The first factor is composed of variables related to disease (disability/chronic conditions/worry about health); the second, to happiness (happiness/emotional); the third, to subjective appraisal of health (physical condition/comparative level of energy/self-rated health status). Finally, the fourth and fifth factors were single variables; restriction of normal activities and social contacts. An interesting finding was that self-rated health status was distributed with almost equal weight in both the first and third factors. A validation of the 10 variables and the 5 factors was undertaken by studying their association with health care utilization. Two measures of utilization were used; number of physicians' visits in a year and number of hospital days in a 4-year period. Number of chronic conditions, disability and self-rated health status were associated with both measures of utilization; factor 1 was the only summary construct showing association with utilization. This paper demonstrates that self-rated health status is valid as a single measure of overall health status in this sample, being associated with both disease and subjective assessment components.

Does the health status of chronically ill patients predict their judgements of the quality of general practice care?

Patients' health status as well as patients' judgements of care are used for assessing patients' perspectives, but the relation between those two concepts is unclear. In this study we explored whether health status predicts patients' judgements of the quality of general practice care. Hand-distributed and mailed surveys were performed by 28 general practitioners in The Netherlands. Chronically ill patients were approached when visiting the general practice or drawn from the practice registers. Health status was measured by WONCA/COOP charts, and patients' judgements by the CEP, a previously validated questionnaire. The response rate was 63% (n = 762). When controlled for other patient characteristics, a poor overall health predicted less positive judgements of medical care, information, counselling, relation and communication, continuity of care and the organization of appointments (p < 0.01). Poor mental well-being predicted less positive judgements of the cooperation between care providers and a stronger need for more care (p < 0.001). The four other aspects of health status did not predict the patients' judgements. Judgements about the premises and the availability for emergencies were not predicted by health status. It can be concluded that a multidimensional approach should be used for interpreting the relations between patients' health status and their judgements of general practice care.

HIV prevalence, risk behaviors, health care use, and mental health status of transgender persons: implications for public health intervention.

OBJECTIVES: This study described HIV prevalence, risk behaviors, health care use, and mental health status of male-to-female and female-to-male transgender persons and determined factors associated with HIV. METHODS: We recruited transgender persons through targeted sampling, respondent-driven sampling, and agency referrals; 392 male-to-female and 123 female-to-male transgender persons were interviewed and tested for HIV. RESULTS: HIV prevalence among male-to-female transgender persons was 35%. African American race (adjusted odds ratio [OR] = 5.81; 95% confidence interval [CI] = 2.82, 11.96), a history of injection drug use (OR = 2.69; 95% CI = 1.56, 4.62), multiple sex partners (adjusted OR = 2.64; 95% CI = 1.50, 4.62), and low education (adjusted OR = 2.08; 95% CI = 1.17, 3.68) were independently associated with HIV. Among female-to-male transgender persons, HIV prevalence (2%) and risk behaviors were much lower. Most male-to-female (78%) and female-to-male (83%) transgender persons had seen a medical provider in the past 6 months. Sixty-two percent of the male-to-female and 55% of the female-to-male transgender persons were depressed; 32% of each population had attempted suicide. CONCLUSIONS: High HIV prevalence suggests an urgent need for risk reduction interventions for male-to-female transgender persons. Recent contact with medical providers was observed, suggesting that medical providers could provide an important link to needed prevention, health, and social services.

The design and use of a health status index for family physicians.

This paper describes a Health Status Index (HSI) which is part of a patient encounter form in a family practice center. The Index, which is used to profile a patient's health status longitudinally, combines physical and psychosocial measures of health. Based on its use in the center and through the presentation of data on patient health status, the authors illustrate how the Index can facilitate the evaluation of care and the management of practice. More specifically, they suggest that such data assist physicians in: (1) evaluating the effect of different modes of treatment on the duration and severity of ill-defined symptoms and complaints; (2) identifying high-risk patients for special attention; (3) indicating treatment modalities which produce more desirable outcomes; (4) determining the efficiency of different modes of treatment and of continued care; and (5) addressing chronological, as well as interpersonal and interprofessional, questions of providing continuous care for the chronically ill.

Factors associated with perceived oral health status in older individuals.

AIM: To assess factors associated with perception of oral health in older individuals. DESIGN: A cross sectional study. SETTING: A densely populated urban area in Sri Lanka. PARTICIPANTS: 585 older adults aged 60 years and above of which 475 were living at home and 110 in institutions. The present analysis is limited to 235 subjects who were subjected to a clinical oral examination. METHOD: The data were collected by means of an interviewer-administered questionnaire and a clinical oral examination. RESULTS: Overall, 48% of the dentate and 42% of the edentate perceived their oral health as poor. The final model of the hierarchical logistic regression analysis for the dentate revealed that presence of retained roots, mobile teeth, >20 missing teeth and perceived need for dental care were significantly associated with poor perceived oral health status. For the edentate, perceived need for dental care, loss of taste sensation and difficulty in eating were significantly associated with poor perceived oral health status. CONCLUSIONS: Factors associated with perceived oral health status differed between the dentate and the edentate. Clinical oral health indicators emerged as significant predictors of perceived oral health status in the dentate although the explanatory power of these indicators on perception of oral health was low.

The short form-12 and the measurement of health status in patients with cerebral aneurysms: performance, validity, and reliability.

OBJECT: Cerebral aneurysms can affect a patient's health status by rupture and stroke, impingement on neural structures, treatment side effects, or psychological stress. The authors assessed the performance, validity, and reliability of the Short Form-12 (SF-12), a self-administered written survey instrument, to assess health status in patients with cerebral aneurysms. METHODS: A cohort of 170 patients with cerebral aneurysms who were seen at a neurosurgery clinic underwent structured interviews including measurement of their health statuses (SF-12 physical component summary [PCS] and mental component summary [MCS]), functional status (Glasgow Outcome Scale score, modified Rankin Scale score, and Barthel Index), and mental health (Hospital Anxiety and Depression Scale score). The SF-12 scores were compared with US population norms by performing t-tests with unequal variances. The validity of the SF-12 was assessed by comparing the PCS and MCS scores with each patient's functional status and mental health scores by using rank-order methods. Inter-item reliability was assessed using the Cronbach alpha statistic. Patients with cerebral aneurysms had decreased health status PCS and MCS scores when compared with population norms (p < 0.001 for all). A history of subarachnoid hemorrhage (SAH) (p = 0.006) and previous surgical or endovascular treatment (p = 0.047) was associated with worse PCS scores. The validity of the SF-12 was supported by the relationship between the PCS and MCS scores and the patient's functional status and mental health (p < 0.001 for all). The reliability of the SF-12 was documented by the Cronbach alpha statistic (alpha = 0.76). CONCLUSIONS: Patients with cerebral aneurysms have a diminished physical and mental health status as measured using the SF-12. The presence of SAH and aneurysm treatment are associated with a worse physical health status. The SF-12 is a valid and reliable instrument for measuring health status in patients with cerebral aneurysms.

Visual Health Information Profile (VHIP). A quantitative approach for analysing the health status of a population.

A new approach for illustrating and analysing the health status of a given population is presented. The concept takes the multi-dimensional nature of health into account. It is based on a clearly out-lined indicator hierarchy, a decile reference system and a computerised information system. The instrument displays the health status of a population and allows comparisons to be made of various health aspects for a given population at different times and allows comparisons to be made of different populations during given time periods. It is possible to represent quantitative and qualitative aspects of health, to monitor the impact of interventions, and to assess the extent to which objectives in the health field have been achieved. Therefore, it can serve as an instrument for communication between policy makers and scientists to manage and to co-ordinate programs that aim at an improvement of the health status and to assist in the priority setting process. The method was applied to several countries using the World Health Organisation's (WHO) "Health For All Global Indicator Database" as the main data source. Country and region specific health status patterns could be generated showing the practicability of the approach. Using a computerised information system, a high degree of transparency and flexibility with respect to the input data and the choices of measurables was achieved.

Impact of maternal mental health status on child mental health treatment outcome.

This study examined the effect of maternal depression and anxiety on child treatment outcome. Psychiatric assessments were conducted on 180 mother-child pairs when the child entered treatment in a community mental health center and six months later. Children whose mothers were depressed or anxious were significantly more impaired than children of mentally healthy mothers at both time points. Both groups of children improved at approximately the same rate. The findings suggest that early mental health screening of children and their mothers may be important preventive practices. Addressing the mental health needs of mothers and children simultaneously may be an effective method of reducing their mental health problems.

Evidence for the sensitivity of the SF-36 health status measure to inequalities in health: results from the Oxford healthy lifestyles survey.

OBJECTIVES: The short form 36 (SF-36) health questionnaire may not be appropriate for population surveys assessing health gain because of the low responsiveness (sensitivity to change) of domains on the measure. An hypothesised health gain of respondents in social class V to that of those in social class I indicated only marginal improvement in self reported health. Subgroup analysis, however, showed that the SF-36 would indicate dramatic changes if the health of social class V could be improved to that of social class I. DESIGN: Postal survey using a questionnaire booklet containing the SF-36 and a number of other items concerned with lifestyles and illness. A letter outlining the purpose of the study was included. SETTING: The sample was drawn from family health services authority (FHSA) computerised registers for Berkshire, Buckinghamshire, Northamptonshire, and Oxfordshire. SAMPLE: The questionnaire was sent to 13,042 randomly selected subjects between the ages of 17-65. Altogether 9332 (72%) responded. OUTCOME MEASURES: Scores for the eight dimensions of the SF-36. STATISTICS: The sensitivity of the SF-36 was tested by hypothesising that the scores of those in the bottom quartile of the SF-36 scores in class V could be improved to the level of the scores from the bottom quartile of SF-36 scores in class I using the effect size statistic. RESULTS: SF-36 scores for the population at the 25th, 50th, and 75th centiles were provided. Those who reported worse health on each dimension of the SF-36 (ie in the lowest 25% of scores) differ dramatically between social class I and V. Large effect sizes were gained on all but one dimension of the SF-36 when the health of those in the bottom quartile of the SF-36 scores in class V were hypothesised to have improved to the level of the scores from the bottom quartile of SF-36 scores in class I. CONCLUSIONS: Analysis of SF-36 data at a population level is inappropriate; subgroup analysis is more appropriate. The data suggest that if it were possible to improve the functioning and wellbeing of those in worst health in class V to those reporting the worst health in class I the improvement would be dramatic. Furthermore, differences between the classes detected by the SF-36 are substantial and more dramatic than might previously have been imagined.
