Self-rated health: a predictor of mortality among the elderly

Data from the Manitoba Longitudinal Study on Aging (MLSA) were used to test the hypothesis that self-rated health (SRH) is a predictor of mortality independent of "objective health status" (OHS). Subjects were a random sample of non-institutionalized residents of Manitoba aged 65+ in 1971 (n = 3,128). A single item measure of SRH was obtained during a survey conducted in 1971; a baseline measure of OHS was derived from physician and self-reported conditions and health service utilization data. Occurrence and date of death during the years 1971-1977 were known. Analyses of the data revealed that, controlling for OHS, age, sex, life satisfaction, income and urban/rural residence, the risk of early mortality (1971-1973) and late mortality (1974-1977) for persons whose SRH was poor was 2.92 and 2.77 times that of those whose SRH was excellent. This increased risk of death associated with poor self-rated health was greater than that associated with poor OHS, poor life satisfaction, low income and being male. These findings provide empirical support for the long held, but inadequately substantiated, belief that the way a person views his health is importantly related to subsequent health outcomes.

Dignity therapy: a novel psychotherapeutic intervention for patients near the end of life

PURPOSE

This study examined a novel intervention, dignity therapy, designed to address psychosocial and existential distress among terminally ill patients. Dignity therapy invites patients to discuss issues that matter most or that they would most want remembered. Sessions are transcribed and edited, with a returned final version that they can bequeath to a friend or family member. The objective of this study was to establish the feasibility of dignity therapy and determine its impact on various measures of psychosocial and existential distress.

PATIENTS AND METHODS

Terminally ill inpatients and those receiving home-based palliative care services in Winnipeg, Canada, and Perth, Australia, were asked to complete pre- and post-intervention measures of sense of dignity, depression, suffering, and hopelessness; sense of purpose, sense of meaning, desire for death, will to live, and suicidality; and a post-intervention satisfaction survey.

RESULTS

Ninety-one percent of participants reported being satisfied with dignity therapy; 76% reported a heightened sense of dignity; 68% reported an increased sense of purpose; 67% reported a heightened sense of meaning; 47% reported an increased will to live; and 81% reported that it had been or would be of help to their family. Post-intervention measures of suffering showed significant improvement (P = .023) and reduced depressive symptoms (P = .05). Finding dignity therapy helpful to their family correlated with life feeling more meaningful (r = 0.480; P = .000) and having a sense of purpose (r = 0.562; P = .000), accompanied by a lessened sense of suffering (r = 0.327; P = .001) and increased will to live (r = 0.387; P = .000).

CONCLUSION

Dignity therapy shows promise as a novel therapeutic intervention for suffering and distress at the end of life.

Mortality and reoperation after open and transurethral resection of the prostate for benign prostatic hyperplasia

As part of an ongoing effort to evaluate alternative treatments for benign prostatic hyperplasia, we compared the outcomes of transurethral resection of the prostate with those of open prostatectomy. Men undergoing prostatectomy in Denmark (n = 36,703), Oxfordshire, England (n = 5284), and Manitoba, Canada (n = 12,090), were identified retrospectively through administrative data and followed for up to eight years. The cumulative percentage of patients undergoing a second prostatectomy was substantially higher after transurethral than after open prostatectomy (12.0 vs. 4.5 percent in Denmark, 12.0 vs. 1.8 percent in Oxfordshire, and 15.5 vs. 4.2 percent in Manitoba). The long-term age-specific mortality rates associated with transurethral prostatectomy as compared with open prostatectomy were also elevated in each country. The data on 1650 Canadian patients were used to investigate the contribution of coexisting morbid conditions to the elevated risk of death. The relative risk was 1.45 (95 percent confidence interval, 1.15 to 1.83) before risk adjustment and 1.45 (95 percent confidence interval, 1.15 to 1.84) after adjustment; the higher mortality was seen among low-risk as well as high-risk patients. These findings suggest that transurethral prostatectomy is less effective in overcoming urinary obstruction than the open operation. Our data also raise the possibility that transurethral prostatectomy may result in higher long-term mortality, although we cannot rule out potential confounding effects of unmeasured characteristics of patients.

Dignity in the terminally ill: a developing empirical model

Despite use of the term dignity in arguments for and against a patient's self-governance in matters pertaining to death, there is little empirical research on how this term has been used by patients who are nearing death. The objective of this study was to determine how dying patients understand and define the term dignity, in order to develop a model of dignity in the terminally ill. A semi-structured interview was designed to explore how patients cope with their advanced cancer and to detail their perceptions of dignity. Interviews were audiotaped and transcribed verbatim. A consecutive sample of 50 consenting patients with advanced terminal cancer were recruited over a 15-month period of time from an urban extended care hospital housing a specialized unit for palliative care. This unit provides both inpatient services. and coordinates end-of-life care community based programming. Data were analysed using latent content analysis and constant comparison techniques. Four members of the research team independently coded the transcribed data, to develop conceptually meaningful categories of responses. Operational definitions were written for major categories, themes and sub-themes. Three major categories emerged from the qualitative analysis, including illness-related concerns; dignity conserving repertoire; and social dignity inventory. These broad categories and their carefully defined themes and sub-themes form the foundation for an emerging model of dignity amongst the dying. The concept of dignity and the dignity model offer a way of understanding how patients face advancing terminal illness. This will serve to promote dignity and the quality of life of patients nearing death.

Risk of developing colorectal cancer following a negative colonoscopy examination: evidence for a 10-year interval between colonoscopies

CONTEXT

Limited evidence exists to guide the optimal frequency of repeat endoscopic examination for colorectal cancer screening after a negative colonoscopy.

OBJECTIVE

To determine the duration and magnitude of the risk of developing colorectal cancer following performance of a negative colonoscopy.

DESIGN, SETTING, AND PATIENTS

Population-based retrospective analysis of individuals whose colonoscopy evaluations did not result in a diagnosis of colorectal neoplasia. Patients who had been evaluated between April 1, 1989, and December 31, 2003, were identified using Manitoba Health's physician billing claims database (N = 35 975). Standardized incidence ratios (SIRs) were calculated to compare colorectal cancer incidence in our cohort with colorectal cancer incidence in the provincial population. Stratified analysis was performed to determine the duration of the reduced risk. Patients with a history of colorectal cancer prior to the index colonoscopy, inflammatory bowel disease, resective colorectal surgery, and lower gastrointestinal endoscopy within the 5 years before the index colonoscopy were excluded. Cohort members were followed up from the time of the index colonoscopy until diagnosis of colorectal cancer, death, out-migration from Manitoba, or end of the study period on December 31, 2003.

MAIN OUTCOME MEASURE

Incidence of colorectal cancer.

RESULTS

A negative colonoscopy was associated with SIRs of 0.69 (95% confidence interval [CI], 0.59-0.81) at 6 months, 0.66 (95% CI, 0.56-0.78) at 1 year, 0.59 (95% CI, 0.48-0.72) at 2 years, 0.55 (95% CI, 0.41-0.73) at 5 years, and 0.28 (95% CI, 0.09-0.65) at 10 years. The proportion of colorectal cancer located in the right side of the colon was significantly higher in the colonoscopy cohort than the rate in the Manitoba population (47% vs 28%; P<.001).

CONCLUSIONS

The risk of developing colorectal cancer remains decreased for more than 10 years following the performance of a negative colonoscopy. There is a need to improve the early detection rate of right-sided colorectal neoplasia in usual clinical practice.

An examination of psychometric properties of the mini-mental state examination and the standardized mini-mental state examination: implications for clinical practice

The Mini-Mental State Examination (MMSE), as developed by Folstein, Folstein, and McHugh (1975), is the most widely used of cognitive screening tools. An examination of the psychometric properties of the MMSE seems warranted because the accurate and comprehensive assessment of mental status can yield profound implications for the quality of life of cognitively impaired older adults (Danner, Beck, Heacock, & Modlin, 1993). In clinical practice, nurses must not only use a valid and reliable screening tool for assessing cognitive impairment, but they must also assess the physical disabilities that may affect client performance and, hence, the cognitive impairment score. The purpose of this study is to examine the psychometric properties of the MMSE in comparison to a more standardized tool and to identify implications of the tool for clinical practice.

Dignity in the terminally ill: a cross-sectional, cohort study

BACKGROUND

Considerations of dignity are often raised in reference to the care of dying patients. However, little research that addresses this issue has been done. Our aim was to identify the extent to which dying patients perceive they are able to maintain a sense of dignity, and to ascertain how demographic and disease-specific variables relate to the issue of dignity in these individuals.

METHODS

We did a cross-sectional study of a cohort of terminally ill patients with cancer, who had a life expectancy of less than 6 months. We enrolled 213 patients from two palliative care units in Winnipeg, Canada, and asked them to rate their sense of dignity. Our main outcome measures included: a 7-point sense of dignity item; the symptom distress scale; the McGill pain questionnaire; the index of independence in activities of daily living (IADL); a quality of life scale; a brief battery of self-report measures, including screening for desire for death, anxiety, hopelessness, and will to live; burden to others; and requirement for social support.

FINDINGS

16 of 213 patients (7.5%; 95% CI 4-11) indicated that loss of dignity was a great concern. These patients were far more than likely than the rest of the cohort to report psychological distress and symptom distress, heightened dependency needs, and loss of will to live.

INTERPRETATION

Loss of dignity is closely associated with certain types of distress often seen among the terminally ill. Preservation of dignity should be an overall aim of treatment and care in patients who are nearing death.

What do patients receiving palliative care for cancer and their families want to be told? A Canadian and Australian qualitative study

OBJECTIVE

To obtain feedback from patients receiving palliative care and their relatives from various ethnic backgrounds about their experiences of the disclosure process and their satisfaction with information sharing during the illness.

DESIGN

A qualitative study with semistructured single interviews.

SETTING

Perth, Western Australia, and Winnipeg, Manitoba, Canada.

PARTICIPANTS

72 participants registered with palliative care: 21 patient-family dyads in Perth and 14 dyads and 2 patients in Winnipeg.

RESULTS

Participants described their experiences in great detail. The analysis indicates that in information sharing the process is as important as the content. The timing, management, and delivery of information and perceived attitude of practitioners were critical to the process. This applied to information interactions at all stages of the illness. Main content areas mentioned related to prognosis and hope. Hope can be conveyed in different ways. Secondary information from various sources is accessed and synthesised with the primary information. All patients, regardless of origin, wanted information about their illness and wanted it fully shared with relatives. Almost all patients requested prognostic information, and all family members respected their wishes. Information was perceived as important for patient-family communication. Information needs of patient and family changed and diverged as illness progressed, and communication between them became less verbally explicit.

CONCLUSIONS

Information delivery for patients needs to be individualised with particular attention to process at all stages of illness. Patients and families use secondary sources of information to complement and verify information given by health carers.

Assessing ecologic proxies for household income: a comparison of household and neighbourhood level income measures in the study of population health status

This paper examines the validity of using ecologic measures of socioeconomic status as proxies for individual-level measures in the study of population health. Based on a representative 5% sample of households in a Canadian province, the study integrated three sources of information: administrative records of individual health care utilization, records of deaths and 1986 census records which contained information on household income and average neighbourhood income. Thirteen measures of health status were developed from these sources of information. The hypothesis that risk estimates derived from ecologic income measures will be attenuated relative to estimates obtained from household income was not supported. These results provide evidence for the use of ecologic-level measures of income in studies which do not have access to individual-level income measures.

How do individuals expect to be viewed by members of lower status groups? Content and implications of meta-stereotypes

Three studies demonstrated that meta-stereotypes held by members of dominant groups about how their group is viewed by a lower status group have important implications for intergroup relations. Study 1 confirmed that White Canadians hold a shared negative meta-stereotype about how they are viewed by Aboriginal Canadians; Studies 2 and 3 extended these results to people's beliefs about an individual out-group member's impressions of them. Feeling stereotyped was associated with negative emotions about intergroup interaction as well as decreases in current self-esteem and self-concept clarity. The perceptions of low- and high-prejudiced persons (LPs and HPs) diverged in a manner consistent with their distinct personal values and group identifications. LPs held a more negative meta-stereotype than did HPs. However, in a one-on-one interaction, HPs sensed that they were stereotyped, whereas LPs felt that they conveyed a counterstereotypical impression.

Drug-associated hospital admissions in older medical patients

A survey of drug-related admissions of patients aged 50 years and older was conducted at the Health Sciences Centre, Winnipeg to determine the interrelationship of risk factors, and isolate the effect of age. All nonelective medical admissions were prospectively assessed to determine the role of drug therapy as a contributory factor. Of the 863 eligible admissions, 162 exhibited at least one drug-related adverse patient event (DRAPE) at the time of hospitalization. This accounted for 19% of the admissions (23% of 718 admissions that involved prescription drugs). Although adverse drug reactions were responsible for many DRAPEs (48%), intentional noncompliance (27%), treatment failure (19%), alcohol (14%), and medication error (10%) were also frequent contributing causes. Drugs commonly implicated in DRAPEs were systemic steroids, digoxin, nonsteroidal anti-inflammatory agents, alpha-methyldopa, calcium channel blockers, beta-blockers, theophylline, furosemide, sympathomimetics, thiazides, and benzodiazepines. The risk of a DRAPE was related to the number of diseases prior to admission (r = 0.81; P less than .026) and the number of drugs used (r = 0.77; P less than .001). Age was not correlated with the risk of a DRAPE. Females had significantly more adverse drug reactions, although sex was not a predictor for overall DRAPE risk.

Registries and administrative data: organization and accuracy

In this article the organization and accuracy of the population registry and administrative data base in Manitoba, Canada are discussed. The overall data management strategy and a framework for analyzing the accuracy of such data are presented. The generally high quality of the Manitoba registry file (necessary to track individuals over time) and the hospital claims is supported by comparisons with other data sources. Hospital claims' main quality problems concern the reliability of certain secondary diagnoses and the level of aggregation necessary for reasonable agreement with other data collection methods (such as chart reviews). Finally, some of the research possibilities associated with population registries and administrative data are outlined.

Isomers of dechlorane plus in Lake Winnipeg and Lake Ontario food webs

The extent of bioaccumulation of the syn- and anti-isomers of Dechlorane Plus (DP) is assessed in archived food web samples from Lake Winnipeg and Lake Ontario. Concentrations of the isomers were determined using purified analytical solutions of individual isomers as opposed to the technical mixture. The syn-isomer was consistently detected in all samples from both lakes; the anti-isomer was detected in all Lake Ontario samples, but only 45% of the samples from Lake Winnipeg. The pattern of bioaccumulation was different for the isomers in Lake Winnipeg. The anti-isomer was dominant in higher trophic level (TL) organisms like walleye [arithmetic mean +/- 1 x standard error: 730 +/- 120 pg/g, lipid weight (1w)] and goldeye (760 +/- 170 pg/g, Iw) while the syn-isomer dominated the lower TL organisms like zooplankton (550 +/- 40 pg/g, Iw) and mussels (430 +/- 140 pg/g, Iw). In Lake Ontario, the extent of bioaccumulation of the isomers and concentrations was greatest in the lower TL benthic organism, Diporeia (syn, 1307 +/- 554; and anti, 3108 +/- 898 pg/g Iw) and also high in zooplankton (syn, 719; and anti, 1332 pg/g Iw). This suggests that the isomers are bioavailable in sediment and that, despite their molecular size, diffusion from the water column into zooplankton can occur. Differences in the mean fractional abundance of the anti-isomer (mean fanti = mean concentration of the anti-isomer divided by sum of mean syn- and anti-concentrations) were pronounced in sediments between lakes (Lake Winnipeg mean fanti = 0.610, Lake Ontario mean fanti = 0.860) and the extent of enrichment (anti-) and depletion (syn-) of the isomers were more marked in Lake Winnipeg biota. There were also differences in the biomagnification potentials, as measured bythe trophic magnification factor (TMF), between the isomers in the Lake Winnipeg food web; no statistically significant TMFs for either isomer were found for the

The Manitoba Project: a re-examination of the link between menopause and depression

This paper re-examines the association between menopause and depression using data from a study in which 477 women were interviewed 6 times over a 3-year period. Menopause is examined as one of a series of factors which may increase the risk of depression for women in middle age, such as children leaving home, the death and illness of family members, the stresses of daily living, health and the onset of chronic disease. Rather than hormonal changes, it seems to be her health coupled with the shifts and stresses of family life in a woman's menopausal years which may trigger her depression.

Limb-girdle muscular dystrophy type 2H associated with mutation in TRIM32, a putative E3-ubiquitin-ligase gene

Limb-girdle muscular dystrophy type 2H (LGMD2H) is a mild autosomal recessive myopathy that was first described in the Manitoba Hutterite population. Previous studies in our laboratory mapped the causative gene for this disease to a 6.5-Mb region in chromosomal region 9q31-33, flanked by D9S302 and D9S1850. We have now used additional families and a panel of 26 microsatellite markers to construct haplotypes. Twelve recombination events that reduced the size of the candidate region to 560 kb were identified or inferred. This region is flanked by D9S1126 and D9S737 and contains at least four genes. Exons of these genes were sequenced in one affected individual, and four sequence variations were identified. The families included in our study and 100 control individuals were tested for these variations. On the basis of our results, the mutation in the tripartite-motif-containing gene (TRIM32) that replaces aspartate with asparagine at position 487 appears to be the causative mutation of LGMD2H. All affected individuals were found to be homozygous for D487N, and this mutation was not found in any of the controls. This mutation occurs in an NHL (named after the proteins NCL1, HT2A, and LIN-41) domain at a position that is highly conserved. NHL domains are known to be involved in protein-protein interactions. Although the function of TRIM32 is unknown, current knowledge of the domain structure of this protein suggests that it may be an E3-ubiquitin ligase. If proven, this represents a new pathogenic mechanism leading to muscular dystrophy.

Health care utilization in males with obstructive sleep apnea syndrome two years after diagnosis and treatment

OBJECTIVE

To document changes in health care utilization (physician claims and hospitalizations) two years after diagnosis and treatment of patients with OSAS.

DESIGN

Prospective observational cohort study.

SETTING

The study was done in the Canadian Province of Manitoba. OSAS patients were selected from a University-based sleep disorders center. Control subjects were selected from the general population.

PATIENTS AND CONTROLS

There were 344 OSAS patients on whom there was utilization data for the period of the study. They were matched to controls from the general population by gender, age, and geographic location.

MEASUREMENTS AND RESULTS

The difference in physician claims between the patients and their matched controls two years after diagnosis and treatment ($174+/-32.4 (SE) per year in Canadian dollars) was significantly less than the difference in the year before diagnosis ($260+/-35.7 (SE), p=0.038). Examining the subgroups of patients adhering (PAT) or not adhering (PNAT) to treatment revealed that the changes were only significant in the patients adhering to treatment. Hospital stays for the entire OSAS group decreased from 1.27 days+0.25(SE) per patient per year one year before diagnosis to 0.54+0.13 per patient per year (p=0.01). The changes in the PAT group (1.25+0.28 per patient per year one year before diagnosis to 0.53+0.14 per patient per year (p=0.034) were significant while in the PNAT group they were not.

CONCLUSIONS

Adherence to treatment in patients with OSAS results in a significant reduction in physician claims and hospital stays.

The use of health-care resources in obesity-hypoventilation syndrome

OBJECTIVE

To document health-care utilization (ie, physician claims and hospitalizations) in patients with obesity-hypoventilation syndrome (OHS), for 5 years prior to the diagnosis and for 2 years after the diagnosis and initiation of treatment.

DESIGN

Retrospective observational cohort study.

SETTING

University-based sleep disorders center in Manitoba, Canada.

PATIENTS AND CONTROL SUBJECTS

Twenty OHS patients (mean [+/- SD] age, 52.7 +/- 9.5 years; body mass index [BMI], 47.3 +/- 11.0 kg/m(2); PaCO(2), 59.7 +/- 13.8 mm Hg; PaO(2), 51.6 +/- 12.4 mm Hg) were matched to two sets of control subjects. First, each case was matched to 15 general population control subjects (GPCs) by age, gender, and geographic location, and, second, each case was matched to a single obese control subject (OBC) who was matched using the same criteria as for the GPCs, plus the measurement of BMI.

MEASUREMENTS AND RESULTS

In the 5 years before diagnosis, the 20 OHS patients had (mean +/- SE) 11.2 +/- 1.8 physician visits per patient per year vs 5.7 +/- 0.8 (p < 0.01) visits for OBCs and 4.5 +/- 0.4 (p < 0.001) visits for GPCs. OHS patients generated higher fees, $623 +/- 96 per patient per year for the 5 years prior to diagnosis compared to $252 +/- 34 (p < 0.001) for OBCs and $236 +/- 25 (p < 0.001) for GPCs. OHS patients were much more likely to be hospitalized than were subjects in either control group in the 5 years prior to diagnosis (odds ratio [OR] vs GPCs, 8.6) (95% confidence interval [CI], 5.9 to 12.7); OR vs OBCs, 4.9 (95% CI, 2.3 to 10.1). In the 2 years after diagnosis and the initiation of treatment (usually continuous positive airway pressure or bilevel positive airway pressure), there was a significant linear reduction in physician fees. In the 2 years after the initiation of treatment, there was a 68.4% decrease in days hospitalized per year (5 years before treatment, 7.9 days per patient per year; after 2 years of treatment, 2.5 days per patient per year [p = 0.01]).

CONCLUSIONS

OHS patients are heavy users of health care for several years prior to evaluation and treatment of their sleep breathing disorder; there is a substantial reduction in days hospitalized once the diagnosis is made and treatment is instituted.

Physician visits, hospitalizations, and socioeconomic status: ambulatory care sensitive conditions in a canadian setting

OBJECTIVE

To determine whether rates of physician visits for ambulatory care sensitive (ACS) conditions are lower for people of low-socioeconomic status than of high-socioeconomic status in an urban population with universal health care coverage.

DATA SOURCES/STUDY SETTING

Physician claims and hospital discharge abstracts from fiscal years 1998 to 2001 for urban residents of Manitoba, Canada. The 1996 Canadian Census public use database provided neighborhood household income information. The study included all continuously enrolled urban residents in the Manitoba Health Services Insurance Plan.

STUDY DESIGN

Twelve ACS conditions definable using 3-digit ICD-9-CM codes permitted cross-sectional and longitudinal comparison of ambulatory visits and hospitalizations. Neighborhood household income data provided a measure of socioeconomic status.

DATA COLLECTION/EXTRACTION METHODS

Files were extracted from administrative data housed at the Manitoba Centre for Health Policy.

PRINCIPAL FINDINGS

All conditions showed a socioeconomic gradient with residents of the lowest income neighborhoods having both more visits and more hospitalizations than their counterparts in higher income areas. Six of nine conditions with a sufficient N showed individuals living in the lowest income neighborhoods to have significantly more ambulatory visits before hospitalization for an ACS condition than did those in the most affluent neighborhoods. Many conditions showed a gradient in rate of hospitalization even after controlling for the number of ambulatory care visits.

CONCLUSIONS

In the Canadian universal health care plan, the poor have reasonable access to ambulatory care for ACS conditions. Ambulatory care may be more effective in preventing hospitalizations among relatively affluent individuals than among the less well off.

Validation of an electronic, population-based prescription database

BACKGROUND

The Drug Programs Information Network (DPIN), Manitoba's (Canada) new electronic prescription database, is a valuable data source for pharmacoepidemiologic research. Pharmacies are required to submit to the DPIN all prescriptions for Pharmacare, the province's drug insurance plan, but submission of prescriptions for social assistance recipients and treaty status Indians is discretionary.

OBJECTIVE

The completeness of the DPIN prescription database was assessed to determine whether treaty status Indians and social assistance recipients were underrepresented.

DESIGN

Prescriptions dispensed during March 13-17, 1995, in a stratified sample of Manitoba pharmacies were linked to DPIN by prescription number to determine the proportions submitted for Indian Affairs, Social Services, and Pharmacare recipients. Pharmacare records in the DPIN were compared with original pharmacy records to evaluate data accuracy.

RESULTS

Of 2196 Indian Affairs and 1879 Social Services prescriptions dispensed in 58 pharmacies, a corresponding prescription was found in the DPIN for 79.7% (98% CI 78.0% to 81.4%) and 90.1% (98% CI 88.8% to 91.4%) of prescriptions, respectively. These proportions were significantly lower than the estimated proportion of Pharmacare prescriptions submitted (93%, 98% CI 92.4% to 93.6%). Ninety-two percent of 8012 DPIN Pharmacare prescriptions matched the original prescription on the drug name, quantity, and days' supply.

CONCLUSIONS

This study established that the DPIN is a valid and reliable data source for studying prescription use among the majority of Manitoban residents. However, the DPIN database has differential validity and underrepresents prescriptions dispensed for the aboriginal population.

Living in a world of our own: the experience of parents who have a child with autism

In this article, we discuss findings of a hermeneutic phenomenological study that sought to describe the experiences of parents who have a child with autism. Qualitative interviews were conducted with parents from 16 families of children with autism residing in a western Canadian province. "Living in a world of our own" emerged as the essence of the parents' experiences. In "living in a world of our own," parents described a world of isolation. Three themes representing the essential challenging elements of the parents' experiences included vigilant parenting, sustaining the self and family, and fighting all the way. Although much is known about the fundamental importance of support to parents of children with chronic conditions and/or disabilities, findings from this study indicate that knowledge has not been adequately transferred to the care of children with autism.

Predictors of successful aging: a twelve-year study of Manitoba elderly

In Manitoba, Canada, a representative cohort of elderly individuals ages 65 to 84 (n = 3,573) were interviewed in 1971 and the survivors of this cohort were reinterviewed in 1983. This analysis assesses the determinants of successful aging--whether or not an individual will live to an advanced age, continue to function well at home, and remain mentally alert. Over 100 separate indicators of demographic and socio-economic status, social supports, health and mental status in 1971 were available as potential predictors of successful aging. Indicators of access to health care over the period 1970-82 and indicators of diseases over this period were also available as predictors. Those who aged successfully were shown to have greater satisfaction with life in 1983 and to have made fewer demands on the health care system than those who aged less well. Despite the large number of potential predictors of successful aging which were examined, only age, four measures of health status, two measures of mental status, and not having one's spouse die or enter a nursing home were shown to be predictive of successful aging.

Pill count, self-report, and pharmacy claims data to measure medication adherence in the elderly

OBJECTIVE

To compare medication adherence calculated from four different data sources including a pill count and self-report obtained during a home medication history, as well as calculations based on refill frequency derived from a provincial prescription claims database (manual and electronic).

DESIGN

Baseline medication adherence was collected as part of a prospective, randomized, controlled study. Mean medication adherence results obtained from the four data sources were compared using repeated-measures ANOVA followed by a Tukey's multiple range test.

SETTING

A pharmacy consultation service located at an interdisciplinary wellness center for noninstitutionalized elderly.

PATIENTS

65 years or older, noninstitutionalized, taking one or more prescribed or nonprescribed medications. Clients would either present to the wellness center or be referred by the Provincial Home Care program.

RESULTS

When calculated from self-report or manual or electronic prescription claims data, mean percent adherence by drug was high and not statistically different (95.8% +/- 17.1%, 107.6% +/- 40.3%, and 94.6% +/- 24.0%, respectively), whereas the pill count adherence was significantly lower at 74.0% +/- 41.5% (p < 0.0001).

CONCLUSIONS

An unexpected finding was that the pill count technique used in this study of elderly clients using chronic, repeat medications appeared to underestimate medication adherence. Numerous other limitations of pill count, self-report, and a province-wide prescription claims database in estimating medication adherence are presented. When using medication adherence as a process measure, the researcher and practitioner should be aware of the limitations unique to the data source they choose, and interpret data cautiously.

What are obstructive sleep apnea patients being treated for prior to this diagnosis?

BACKGROUND

Patients with obstructive sleep apnea syndrome (OSAS) use health-care resources at higher rates than control subjects for years prior to diagnosis. Although obesity and certain cardiovascular disorders are more common in OSAS patients, the precise cause of increased health-care utilization is unclear.

OBJECTIVES

To examine the causes of increased utilization, and what patients with OSAS were being treated for prior to this diagnosis.

METHODS

We compared the records of 773 patients with OSAS to those of age-, gender-, geographic-, and physician-matched control subjects from the general population.

RESULTS

We found that sleep apnea patients used 23 to 50% more resources (defined by physician fees, physician visits, and hospital nights) in the 5 years prior to diagnosis than did control subjects. We examined the diagnoses made and found that apnea patients are at higher risk for hypertension (odds ratio [OR], 2.5; 95% confidence interval [CI], 2.0 to 3.3), congestive heart failure (OR, 3.9; 95% CI, 1.7 to 8.9), cardiac arrhythmias (OR, 2.2; 95% CI, 1.2 to 4.0), cardiovascular disease (OR, 2.6; 95% CI, 2.0 to 3.3), chronic obstructive airways disease (OR, 1.6; 95% CI, 1.2 to 2.0), and depression (OR, 1.4; 95% CI, 1.0 to 1.9). To control for the confounding effects of obesity and to determine the independent effects of body mass index (BMI), gender, age, degree of hypoxemia, apnea-hypopnea index, and sleepiness in the 773 patients, we performed a logistic regression analysis with the dependent variable being diagnosis, and a linear regression analysis with the dependent variable being measures of health-care utilization. Age and BMI were significant independent predictors of most cardiovascular diagnoses and arthropathy. Male gender predicted ischemic heart disease (OR, 2.98; 95% CI, 1.36 to 6.54), and female gender was predictive of chronic obstructive airways disease (OR, 2.63; 95% CI, 1.85 to 3.72) and depression (OR, 2.24; 95% CI, 1.45 to 3.44). The best model predicting health-care utilization measures was comprised of age, gender, and BMI, and explained 9%, 14%, and 8% of the variability in physician fees, number of physician claims, and number of physician visits, respectively.

CONCLUSION

Of all comorbid diagnoses, significantly increased utilization was found for cardiovascular disease and especially hypertension in the OSAS patients.

Adaptive and maladaptive perfectionism in medical students: a longitudinal investigation

OBJECTIVES

The personality of medical students may have an important impact on both their academic performance and emotional adjustment during medical school. There has been little systematic study of the impact of perfectionism on medical students. The present study sought to compare the perfectionism profile of medical students with that of a general arts student group and to examine the relationship among perfectionism, distress symptoms and academic expectations and satisfaction.

DESIGN

Medical students (n=96) and arts students (n=289) completed a baseline assessment including two multidimensional perfectionism scales. The medical students also completed measures of distress symptoms, personality (neuroticism, conscientiousness) and questions about their perceptions of their academic performance. Of the medical students, 58 completed a second set of questionnaires 6 months later (time 2).

SUBJECTS

First-, second- and third year medical students and first-year arts students.

RESULTS

In comparison with arts students, the perfectionism profile of medical students showed higher personal standards, lower doubts about actions and lower maladaptive perfectionism scores. In the medical students adaptive perfectionism (achievement striving) was significantly correlated with baseline academic performance expectations and conscientiousness and was predictive of dissatisfaction with academic performance at time 2. Maladaptive perfectionism (excessive evaluative concerns) was significantly correlated with baseline distress symptoms and neuroticism and was predictive of symptoms of depression and hopelessness at time 2.

CONCLUSIONS

Perfectionism in medical students differs systematically from perfectionism in general arts students. Distinguishing adaptive and maladaptive aspects of perfectionism is important in understanding the cross-sectional and longitudinal implications of perfectionism for medical students.

Feasibility of dialectical behavior therapy for suicidal adolescent inpatients

OBJECTIVE

To evaluate the feasibility of dialectical behavior therapy (DBT) implementation in a general child and adolescent psychiatric inpatient unit and to provide preliminary effectiveness data on DBT versus treatment as usual (TAU).

METHOD

Sixty-two adolescents with suicide attempts or suicidal ideation were admitted to one of two psychiatric inpatient units. One unit used a DBT protocol and the other unit relied on TAU. Assessments of depressive symptoms, suicidal ideation, hopelessness, parasuicidal behavior, hospitalizations, emergency room visits, and adherence to follow-up recommendations were conducted before and after treatment and at 1-year follow-up for both groups. In addition, behavioral incidents on the units were evaluated.

RESULTS

DBT significantly reduced behavioral incidents during admission when compared with TAU. Both groups demonstrated highly significant reductions in parasuicidal behavior, depressive symptoms, and suicidal ideation at 1 year.

CONCLUSIONS

DBT can be effectively implemented in acute-care child and adolescent psychiatric inpatient units. The promising results from this pilot study suggest that further evaluation of DBT for adolescent inpatients appears warranted.
