Can a naturally depauperate Ephemeroptera, Plectoptera and Trichoptera (EPT) fauna track river degradation in south-western Australia?

Freshwater aquatic ecosystems are threatened globally. Biological monitoring is required to deliver rapid and replicable assessment of changes in habitat quality. The Ephemeroptera, Plectoptera, Trichoptera (EPT) index is a globally recognised rapid bioassessment that measures taxa richness of three insect orders whose larvae are considered sensitive to freshwater habitat degradation. South-western Australia contains threatened freshwater ecosystems but has depauperate EPT fauna and high endemism, potentially reducing the capacity of the EPT index to track degradation. This study investigated if EPT species richness, composition or individual species tracked physical or chemical river degradation in three catchments in south-western Australia. We sampled EPT fauna and measured water chemistry, erosion, sedimentation, riparian vegetation cover and instream habitat at 98 sites in the winters of 2007 and 2023. We found 35 EPT taxa across the study area with a median number of species per site of two. EPT species richness had weak positive associations with a composite water quality index and dissolved oxygen and weak negative associations with electrical conductivity and total nitrogen. No association was found between physical and fringing zone degradation measures and EPT species richness. EPT community structure generally did not distinguish between sites with high or low degradation levels. The presence of the mayfly Nyungara bunni tracked salinity, dissolved oxygen and nitrogen levels, but its usefulness as a bioindicator could be limited by its restricted range. This study suggests that the EPT index would need modification or combination with other indices to be a useful rapid bioassessment in south-western Australia.

Single-Blinded Randomized Controlled Study on Use of Interactive Distraction Versus Oral Midazolam to Reduce Pediatric Preoperative Anxiety, Emergence Delirium, and Postanesthesia Length of Stay.

PURPOSE: The purpose of this study was to compare effects of tablet-based interactive distraction (TBID; 1 minute preseparation) with oral midazolam (15 to 45 minutes of preseparation) on preoperative anxiety, emergence delirium, and postanesthesia length of stay in children, 4 to 12 years undergoing outpatient surgery. DESIGN: Single-blinded prospective design with randomized assignment to TBID or oral midazolam group was conducted at a large pediatric hospital in southwestern United States. METHODS: A total of 102 children and caregivers were enrolled. Outcome measures included anxiety scores at baseline, separation, and mask induction; postemergence delirium scores; caregiver ratings of child anxiety and satisfaction; and time from postanesthesia care unit arrival to discharge and posthospital behaviors. FINDINGS: The TBID group demonstrated significantly lower anxiety at separation and mask induction (P < .001) and emergence delirium at 15 minutes postawakening (P = .001), were extubated earlier (P = .007), arrived to phase II earlier (P = .03), and discharged earlier (P = .0001). CONCLUSIONS: TBID was more effective than oral midazolam in reducing preoperative anxiety, emergence delirium, and postanesthesia length of stay.

Behaviours and attitudes of recreational fishers toward safety at a 'blackspot' for fishing fatalities in Western Australia.

Issue addressed Recreational fishing, particularly rock fishing, can be dangerous; 30 fatalities were recorded in Western Australia from 2002-2014. This study investigates differences in behaviours and attitudes towards safety among fishers at a fishing fatality 'black spot' in Australia. Methods A total of 236 fishers were surveyed at Salmon Holes, Western Australia in 2015. Fishers were grouped by country of origin and significant differences among groups for behaviours and attitudes towards personal safety were identified. Results Of fishers surveyed, 53% were born in Asia. These fishers self-assessed as poorer swimmers (F=23.27, P<0.001), yet were more likely to have fished from rocks (χ2=20.94, P<0.001). They were less likely to go close to the water to get a snagged line (χ2=15.44, P<0.001) or to drink alcohol while fishing ( χ2 = 8.63, P<0.001), and were more likely to agree that they would drown if swept into the sea (χ2=9.49, P<0.001). Although most respondents agreed that wearing a life jacket made fishing safer, 78% 'never' wore a life jacket while fishing. Conclusions Some fishers who were poor swimmers and were aware of the dangers of rock fishing still choose to fish from rocks. So what? Our results support the proposal that the wearing of life jackets should be promoted, if not made mandatory, while water safety education campaigns should be continued and target vulnerable communities.

Multisite Randomized Controlled Trial to Compare Two Methods of Tinnitus Intervention to Two Control Conditions.

OBJECTIVES: In this four-site clinical trial, we evaluated whether tinnitus masking (TM) and tinnitus retraining therapy (TRT) decreased tinnitus severity more than the two control groups: an attention-control group that received tinnitus educational counseling (and hearing aids if needed; TED), and a 6-month-wait-list control (WLC) group. The authors hypothesized that, over the first 6 months of treatment, TM and TRT would decrease tinnitus severity in Veterans relative to TED and WLC, and that TED would decrease tinnitus severity relative to WLC. The authors also hypothesized that, over 18 months of treatment, TM and TRT would decrease tinnitus severity relative to TED. Treatment effectiveness was hypothesized not to be different across the four sites. DESIGN: Across four Veterans affairs medical center sites, N = 148 qualifying Veterans who experienced sufficiently bothersome tinnitus were randomized into one of the four groups. The 115 Veterans assigned to TM (n = 42), TRT (n = 34), and TED (n = 39) were considered immediate-treatment subjects; they received comparable time and attention from audiologists. The 33 Veterans assigned to WLC were, after 6 months, randomized to receive delayed treatment in TM, TRT, or TED. Assessment of outcomes took place using the Tinnitus Handicap Inventory (THI) at 0, 3, 6, 12, and 18 months. RESULTS: Results of a repeated measures analysis of variance using an intention-to-treat approach showed that the tinnitus severity of Veterans receiving TM, TRT, and TED significantly decreased (p < 0.05) relative to Veterans in the WLC group at 3 months (effect sizes = 0.44, 0.52, and 0.27, respectively) and at 6 months (effect sizes = 0.52, 0.56, and 0.40, respectively). Analyses comparing effectiveness of TM, TRT, and TED over 18 months revealed that the three conditions were not significantly different, but that tinnitus severity in the combined groups significantly decreased (p < 0.01) from baseline to 3 months (5.6 THI points) and from 3 to 6 months (3.7 THI points). With respect to clinically significant change, about half of Veterans who received TM (55%), TRT (59%), or TED (46%) showed strong or modest improvement on the THI by 18 months. Without treatment, the WLC group did not show significant change. Treatment effectiveness did not differ by study site. CONCLUSIONS: Audiologists who provided interventions to Veterans with bothersome tinnitus in the regular clinic setting were able to significantly reduce tinnitus severity over 18 months using TM, TRT, and TED approaches. These results suggest that TM, TRT, and TED, when implemented as in this trial, will provide effectiveness that is relatively similar by 6 months and beyond.

An internal quality improvement collaborative significantly reduces hospital-wide medication error related adverse drug events.

OBJECTIVE: To reduce the rate of harmful adverse drug events (ADEs) of severity level D-I from a baseline peak of 0.24 ADE/1000 doses to 0.08 ADE/1000 doses. STUDY DESIGN: A hospital-wide, quasi-experimental time series quality improvement (QI) initiative to reduce ADEs was implemented. High-reliability concepts, microsystem-based multidisciplinary teams, and QI science methods were used. ADEs were detected through a combination of voluntary reporting, trigger tool analysis, reversal agent review, and pharmacy interventions. A multidisciplinary ADE Quality Collaborative focused on medication use processes, not on specific classes of medications. Effective interventions included huddles and an ADE prevention bundle. RESULTS: The rate of harmful ADEs initially increased by >65% because of increased error reporting, temporally associated with the implementation of a program focused on high reliability and an improved safety culture. The quarterly rate was 0.17 ADE/1000 dispensed doses in Q1 2010. By the end of Q2 2013, the rate had decreased by 76.5%, to 0.04 ADE/1000 dispensed doses (P < .001). CONCLUSION: Using an internal collaborative model and QI methodologies focused on medication use processes, harmful ADEs were reduced hospital-wide by 76.5%. The concurrent implementation of a high-reliability, safety-focused program was important as well.

How Concurrent Services Obscured Detection of Intervention Benefits: Part 2: Secondary Analysis of the PREP Trial for Frail Older Adults and Family Caregivers.

Family caregivers frequently use health and social services to support their caregiving. In evaluating care-giving interventions, however, researchers rarely examine the influences of such concurrent services on intervention effectiveness. In this Part 2 secondary analysis of data from the Oregon Health & Science University/Kaiser Permanente Northwest Region Family Care Study, we examined the moderating influences of concurrent services on intervention effectiveness. The Family Care Study was a randomized controlled trial to evaluate the preparedness, skill, enrichment, and predictability (PREP) intervention with caregivers of frail older adults referred for skilled home health. Compared with control caregivers receiving usual home health care (n = 103), PREP intervention caregivers (n = 104) reported greater improvements in family care (effect size, d = 0.58). We conducted follow-up analyses to determine whether PREP was differentially effective depending on whether dyads received concurrent Social Health Maintenance Organization (SHMO) services, concurrent hospice services, or neither. In the 55% of dyads not receiving SHMO or hospice, we found that PREP's effects were large compared to usual care (d = 1.16, p < 0.001). PREP's effects were not significant for dyads receiving concurrent SHMO or hospice services. Results highlight the strong benefits of hospice for control dyads, but reveal difficulties in evaluating intervention effectiveness when dyads receive concurrent services.

How Tailoring Led to Variation in Care Issues, Dosage, and Outcomes: Part 1: Secondary Analysis of the PREP Trial for Frail Older Adults and Family Caregivers.

In family caregiving interventions for adults with health problems, tailoring has become the norm. Studies that evaluate tailored interventions, however, have rarely included intentional variation in dosage or explored the dosage-outcome association. In this Part 1 secondary analysis, we examine dosage and outcomes in intervention families (N = 116) who participated in the Oregon Health & Science University/Kaiser Permanente Northwest Region Family Care Study. The Family Care Study was a randomized controlled trial to evaluate the preparedness, skill, enrichment, and predictability (PREP) intervention with caregiving families of frail older adults referred for skilled home health. Tailoring of PREP began with assessment by the PREP nurse. Families then identified and selected care-related issues to work on with their PREP nurse; family needs and preferences guided the number and timing of nurse visits and calls. Families selected a median of 3 (range = 0 to 10) care-related issues in five categories: direct care (chosen by 57% of families), transitions (40%), caregiver strain and health (40%), arranging care (33%), and enrichment (22%). The number of issues strongly predicted number of PREP nurse visits and calls, whereas nurse visits in turn predicted caregivers' reports of improved family care and usefulness of home health assistance, highlighting the importance of visits for achieving outcomes.

The tinnitus functional index: development of a new clinical measure for chronic, intrusive tinnitus.

OBJECTIVES: Chronic subjective tinnitus is a prevalent condition that causes significant distress to millions of Americans. Effective tinnitus treatments are urgently needed, but evaluating them is hampered by the lack of standardized measures that are validated for both intake assessment and evaluation of treatment outcomes. This work was designed to develop a new self-report questionnaire, the Tinnitus Functional Index (TFI), that would have documented validity both for scaling the severity and negative impact of tinnitus for use in intake assessment and for measuring treatment-related changes in tinnitus (responsiveness) and that would provide comprehensive coverage of multiple tinnitus severity domains. DESIGN: To use preexisting knowledge concerning tinnitus-related problems, an Item Selection Panel (17 expert judges) surveyed the content (175 items) of nine widely used tinnitus questionnaires. From those items, the Panel identified 13 separate domains of tinnitus distress and selected 70 items most likely to be responsive to treatment effects. Eliminating redundant items while retaining good content validity and adding new items to achieve the recommended minimum of 3 to 4 items per domain yielded 43 items, which were then used for constructing TFI Prototype 1.Prototype 1 was tested at five clinics. The 326 participants included consecutive patients receiving tinnitus treatment who provided informed consent-constituting a convenience sample. Construct validity of Prototype 1 as an outcome measure was evaluated by measuring responsiveness of the overall scale and its individual items at 3 and 6 mo follow-up with 65 and 42 participants, respectively. Using a predetermined list of criteria, the 30 best-functioning items were selected for constructing TFI Prototype 2.Prototype 2 was tested at four clinics with 347 participants, including 155 and 86 who provided 3 and 6 mo follow-up data, respectively. Analyses were the same as for Prototype 1. Results were used to select the 25 best-functioning items for the final TFI. RESULTS: Both prototypes and the final TFI displayed strong measurement properties, with few missing data, high validity for scaling of tinnitus severity, and good reliability. All TFI versions exhibited the same eight factors characterizing tinnitus severity and negative impact. Responsiveness, evaluated by computing effect sizes for responses at follow-up, was satisfactory in all TFI versions.In the final TFI, Cronbach's alpha was 0.97 and test-retest reliability 0.78. Convergent validity (r = 0.86 with Tinnitus Handicap Inventory [THI]; r = 0.75 with Visual Analog Scale [VAS]) and discriminant validity (r = 0.56 with Beck Depression Inventory-Primary Care [BDI-PC]) were good. The final TFI was successful at detecting improvement from the initial clinic visit to 3 mo with moderate to large effect sizes and from initial to 6 mo with large effect sizes. Effect sizes for the TFI were generally larger than those obtained for the VAS and THI. After careful evaluation, a 13-point reduction was considered a preliminary criterion for meaningful reduction in TFI outcome scores. CONCLUSIONS: The TFI should be useful in both clinical and research settings because of its responsiveness to treatment-related change, validity for scaling the overall severity of tinnitus, and comprehensive coverage of multiple domains of tinnitus severity.

Integrated taxonomy reveals new threatened freshwater mussels (Bivalvia: Hyriidae: Westralunio) from southwestern Australia.

The freshwater mussel Westralunio carteri (Iredale, 1934) has long been considered the sole Westralunio species in Australia, limited to the Southwest and listed as vulnerable on the IUCN Red List and under Australian legislation. Here, we used species delimitation models based on COI mtDNA sequences to confirm existence of three evolutionarily significant units (ESUs) within this taxon and conducted morphometric analyses to investigate whether shell shape differed significantly among these ESUs. "W. carteri" I was found to be significantly larger and more elongated than "W. carteri" II and "W. carteri" II + III combined, but not different from "W. carteri" III alone. We recognise and redescribe "W. carteri" I as Westralunio carteri (Iredale, 1934) from western coastal drainages and describe "W. carteri" II and "W. carteri" III as Westralunio inbisi sp. nov. from southern and lower southwestern drainages. Two subspecies are further delineated: "W. carteri" II is formally described as Westralunio inbisi inbisi subsp. nov. from southern coastal drainages, and "W. carteri" III as Westralunio inbisi meridiemus subsp. nov. from the southwestern corner. Because this study profoundly compresses the range of Westralunio carteri northward and introduces additional southern and southwestern taxa with restricted distributions, new threatened species nominations are necessary.

Persistence of virus-specific immune responses in the central nervous system of mice after West Nile virus infection.

BACKGROUND: West Nile virus (WNV) persists in humans and several animal models. We previously demonstrated that WNV persists in the central nervous system (CNS) of mice for up to 6 months post-inoculation. We hypothesized that the CNS immune response is ineffective in clearing the virus. RESULTS: Immunocompetent, adult mice were inoculated subcutaneously with WNV, and the CNS immune response was examined at 1, 2, 4, 8, 12 and 16 weeks post-inoculation (wpi). Characterization of lymphocyte phenotypes in the CNS revealed elevation of CD19+ B cells for 4 wpi, CD138 plasma cells at 12 wpi, and CD4+ and CD8+ T cells for at least 12 wpi. T cells recruited to the brain were activated, and regulatory T cells (Tregs) were present for at least 12 wpi. WNV-specific antibody secreting cells were detected in the brain from 2 to 16 wpi, and virus-specific CD8+ T cells directed against an immunodominant WNV epitope were detected in the brain from 1 to 16 wpi. Furthermore, these WNV-specific immune responses occurred in mice with and without acute clinical disease. CONCLUSIONS: Virus-specific immune cells persist in the CNS of mice after WNV infection for up to 16 wpi.

An assessment of the impacts of timber plantations on water quality and biodiversity values of Marbellup Brook, Western Australia.

Despite the fact that the establishment and maintenance of blue gum plantations can potentially result in the removal of riparian vegetation, the presence of increased levels of sediments, pesticides, and nutrients, and consequently, the loss of in-stream biodiversity, few studies exist that have looked at the impacts of timber plantations on in-stream biota. The goals of this study were thus to determine water quality, riparian condition, and in-stream biodiversity values of local streams draining blue gum plantations in the Marbellup Brook catchment in Western Australia and to compare these values with those of streams associated with other land uses. Selected water quality and habitat variables and in-stream macroinvertebrate biodiversity were measured in 2006 and 2007 at 28 sites falling into five broad categories based on the predominant land use within 200 m of each study reach. Overall, the results indicated that "blue gum plantation" sites often had better water quality, riparian condition, and biodiversity values than "pasture unfenced," and sometimes "pasture fenced" sites, but water quality and biodiversity values at these sites were not as good as those associated with "remnant" native vegetation sites. The location of the blue gum plantation sites along the disturbance gradient investigated was attributed to both present management and past land uses in the subcatchments investigated. As this study was conducted at a time when blue gum plantations were in an on-growing phase, it was recommended that future research on the impact of blue gum plantations on waterways in southwestern Australia should include an investigation of the impacts of timber clear-cutting and extraction. Longer-term cumulative and downstream effects of blue gum plantations on local waterways also need to be investigated.

Does age make a difference in caregiver strain? Comparison of young versus older caregivers in early-stage Parkinson's disease.

Family care research has identified negative outcomes of providing care to a spouse with Parkinson's disease (PD), such as declining physical and mental health. Research has also identified protective variables that decrease negative outcomes such as high mutuality and rewards of meaning. It is important for clinicians to identify "at risk" family caregivers and provide earlier interventions. Despite the importance of age and developmental stage there is a paucity of research comparing young versus older spouse caregivers. This study compared the difference in negative aspects of strain and modulators of strain in young and older PD spouse caregivers. A series of hierarchical multiple regressions were used to examine the contribution of age on both positive and negative aspects of the care situation for 65 (37 young, 28 old) PD spouse caregivers. Negative variables included 3 dimensions of strain; strain from lack of personal resources, strain from worry, and global strain. Positive or protective variables included mutuality, preparedness, and rewards of meaning. Even in early stage disease before significant care is required, young spouses (40-55) were found to be at greater risk for negative consequences of the care situation reporting significantly more strain from lack of personal resources, and lower levels of mutuality and rewards of meaning than older (greater than 70) spouses. As expected, young spouses were more likely to be working, caring for children in the home, and in better physical health than older spouses. Clinicians are well-situated to identify the unique needs of young spouses and intervene early in the caregiving trajectory. These findings provide ideas for targeted interventions. Future larger studies that compare young and older spouses should include later stage disease to more fully understand the developmental differences raised by the present findings.

Effectiveness of an aspiration risk-reduction protocol.

BACKGROUND: Aspiration of gastric contents is a serious problem in critically ill, mechanically ventilated patients receiving tube feedings. OBJECTIVES: The purpose of this study was to evaluate the effectiveness of a three-pronged intervention to reduce aspiration risk in a group of critically ill, mechanically ventilated patients receiving tube feedings. METHODS: A two-group quasi-experimental design was used to compare outcomes of a usual care group (December 2002-September 2004) with those of an Aspiration Risk-Reduction Protocol (ARRP) group (January 2007-April 2008). The incidence of aspiration and pneumonia was compared between the usual care group (n = 329) and the ARRP group (n = 145). The ARRP had three components: maintaining head-of-bed elevation at 30 degrees or higher, unless contraindicated; inserting feeding tubes into distal small bowel, when indicated; and using an algorithmic approach for high gastric residual volumes. RESULTS: Two of the three ARRP components were implemented successfully. Almost 90% of the ARRP group had mean head-of-bed elevations of 30 degrees or higher as compared to 38% in the usual care group. Almost three fourths of the ARRP group had feeding tubes placed in the small bowel as compared with less than 50% in the usual care group. Only three patients met the criteria for the high gastric residual volume algorithm. Aspiration was much lower in the ARRP group than that in the usual care group (39% vs. 88%, respectively). Similarly, pneumonia was much lower in the ARRP group than that in the usual care group (19% vs. 48%, respectively). DISCUSSION: Findings from this study suggest that a combination of a head-of-bed position elevated to at least 30 degrees and use of a small-bowel feeding site can reduce the incidence of aspiration and aspiration-related pneumonia dramatically in critically ill, tube-fed patients.

Development of the Ways Of Helping Questionnaire: a measure of preferred coping strategies for older African American cancer survivors.

Although researchers have identified beneficial coping strategies for cancer patients, existing coping measures do not capture the preferred coping strategies of older African American cancer survivors. A new measure, the Ways of Helping Questionnaire (WHQ), was evaluated with 385 African American cancer survivors. Validity evidence from factor analysis resulted in 10 WHQ subscales (Others There for Me, Physical and Treatment Care Needs, Help from God, Church Family Support, Helping Others, Being Strong for Others, Encouraging My Healthy Behaviors, Others Distract Me, Learning about Cancer, and Distracting Myself). Reliability evidence was generally strong. Evidence regarding hypothesized relationships with measures of well-being and another coping measure was mixed. The WHQ's content coverage makes it especially relevant for older African American cancer survivors.

Freshwater tributaries provide refuge and recolonization opportunities for mussels following salinity reversal.

Reversing the effects of secondary salinization, and its impacts on aquatic biodiversity, is a growing global challenge, and particularly prevalent in Mediterranean-climate regions. Remnant freshwater tributaries in salinized landscapes provide significant biodiversity values, including discrete areas of refuge, dilution of salinized reaches, and potential source populations for recolonisation. The importance of these areas for aquatic fauna is widely accepted but rarely evaluated in the field. This study explored how spatial distribution of southwestern Australia's only freshwater mussel species, Westralunio carteri, has responded to the ongoing salinity trend in the Kent River catchment. Our results showed that salinity in the river has begun to reverse following improved catchment management, and also detected the first evidence of an associated recovery of the freshwater mussel population. Mussels in the mainstem were limited to sites around and downstream of a permanently flowing freshwater tributary, suggesting that dilution from this source provides a refuge in the lower reach. At two of those sites, all individuals were <15 years of age, indicative of recolonisation coinciding with salinity reversal around the turn of the century. Interestingly, mussels clearly persisted in other parts of the lower reach throughout the peak salinity period, when salinities regularly exceeded laboratory derived toxicity thresholds for the species. Mussels were not found in the majority of the mainstem or in highly acidic parts of the freshwater tributaries. The presence of old shells at those sites shows that the species was once widespread, and that the current distribution probably reflects a contraction due to historical salinization as well as acidification. Overall, our results show that the W. carteri population in the catchment has taken a first step towards recovery, and highlights the importance of freshwater tributaries in providing both refuge from disturbance and a source of new recruits.

Paramedics providing palliative care at home: A mixed-methods exploration of patient and family satisfaction and paramedic comfort and confidence.

OBJECTIVE: Paramedics Providing Palliative Care at Home was launched in two provinces, including a new clinical practice guideline, database, and paramedic training. The aim of this study was to evaluate patient/family satisfaction and paramedic comfort and confidence. METHODS: In Part A, we gathered perspectives of patients/families via surveys mailed at enrolment and telephone interviews after an encounter. Responses were reported descriptively and by thematic analysis. In Part B, we surveyed paramedics online pre- and 18 months post-launch. Comfort and confidence were scored on a 4-point Likert scale, and attitudes on a 7-point Likert scale, reported as the median (interquartile range [IQR]); analysis with Wilcoxon ranked sum/thematic analysis of free text. RESULTS: In Part A, 67/255 (30%) enrolment surveys were returned. Three themes emerged: fulfilling wishes, peace of mind, and feeling prepared for emergencies. In 18 post-encounter interviews, four themes emerged: 24/7 availability, paramedic professionalism and compassion, symptom relief, and a plea for program continuation. Thematic saturation was reached with little divergence. In Part B, 235/1255 (18.9%) pre- and 267 (21.3%) post-surveys were completed. Comfort with providing palliative care without transport improved post launch (p = < 0.001) as did confidence in palliative care without transport (p = < 0.001). Respondents strongly agreed that all paramedics should be able to provide basic palliative care. CONCLUSIONS: After implementation of the multifaceted Paramedics Providing Palliative Care at Home Program, paramedics describe palliative care as important and rewarding. The program resulted in high patient/family satisfaction; simply registering provides peace of mind. After an encounter, families particularly noted the compassion and professionalism of the paramedics.

CONTEXTE: Un programme de prestation de soins palliatifs à domicile par des ambulanciers paramédicaux a été lancé dans deux provinces, précédé de l'extension d'un guide de pratique clinique, de la mise à jour d'une base de données et de l'élaboration d'une formation particulière à l'intention des ambulanciers paramédicaux. Ont été évalués le degré de satisfaction des patients et des familles ainsi que le degré d'aisance et de confiance des ambulanciers paramédicaux. MÉTHODE: Dans la partie A, il y a eu collecte de données sur le point de vue des patients et des familles à l'aide d'un questionnaire d'enquête envoyé par la poste au moment de la sélection et d'entrevues téléphoniques après les rencontres. Les réponses ont été présentées en style descriptif et sous forme d'analyse thématique. Dans la partie B, une enquête en ligne a été menée parmi les ambulanciers paramédicaux avant le lancement du programme et 18 mois après celui-ci. Le degré d'aisance et de confiance a été évalué sur une échelle de Likert de 4 points, et les attitudes, sur une échelle de Likert de 7 points; les résultats ont été exprimés sous forme d'intervalles interquartiles (IQ) médians; l'analyse des données, calculée à l'aide du test de Wilcoxon, et les textes libres, présentés sous forme d'analyse thématique. RÉSULTATS: Dans la partie A, 67 questionnaires sur 255 (30%) ont été remis. Trois thèmes importants se sont dégagés des réponses : la satisfaction des désirs, la tranquillité d'esprit et le sentiment de préparation à toute éventualité. Par ailleurs, il y a eu 18 entrevues après les rencontres, desquelles se sont dégagés quatre grands thèmes : la disponibilité des soins 24 h sur 24, 7 jours sur 7; le professionnalisme et la compassion des ambulanciers paramédicaux; le soulagement des symptômes et un appel pressant en faveur de la poursuite du programme. La saturation thématique s'est obtenue avec un faible degré de divergence. Dans la partie B, 235 questionnaires sur 1255 (18,9%) ont été remplis avant le lancement du programme, et 267 sur 1255 (21,3%), après la mise en œuvre. Le degré d'aisance et la prestation de soins palliatifs, dans le contexte d'absence de transport des malades, se sont améliorés après le lancement (p ( 0,001); il en allait de même pour le degré de confiance dans la prestation de soins palliatifs, dans le même contexte (p ( 0,001). Les répondants étaient fortement d'avis que tous les ambulanciers paramédicaux devraient être en mesure de fournir des soins palliatifs de base. CONCLUSION: Après la mise en œuvre de ce programme à volets multiple, les ambulanciers paramédicaux considéraient la prestation de soins palliatifs comme un geste important et gratifiant. Le programme a donné lieu à un degré élevé de satisfaction tant des patients que des familles, et la facilité d'inscription a procuré la tranquillité d'esprit. Enfin, après une rencontre, les familles ont souligné tout particulièrement le professionnalisme et la compassion des ambulanciers paramédicaux.

Do motor and nonmotor symptoms in PD patients predict caregiver strain and depression?

Our objective was to understand the impact of motor and nonmotor symptoms of patients with early and middle stage Parkinson's disease (PD) on their spouses' caregiver strain and depression. A sample of 219 spouse caregivers of PD patients participating in a clinical trial was evaluated for six dimensions of caregiver strain and depression using the Family Care Inventory. Motor and nonmotor (i.e., psychological) clinical symptoms collected from PD patients as part of the clinical trial protocol were used as predictors. Seven hierarchical regression analyses were used to determine the contribution of the motor and nonmotor clinical symptoms in explaining variation in each of the seven caregiver-dependent variables. Clinical symptoms explained 9-16% of the variance in caregiver strain and 10% of depression. Motor symptoms explained 0-6% of the variance and nonmotor psychological symptoms explained 7-13% of the variance in caregiver strain. Comparing our findings with literature that is deemed clinically relevant for patient symptoms that predict caregiver strain, we concluded that PD patient symptoms are important predictors of caregiver strain and depression. Patient nonmotor psychological symptoms have a much greater impact on caregiver strain and depression than patient motor symptoms.

Tinnitus outcomes assessment.

Over the past two decades, recognition has grown that measures for evaluating treatment outcomes must be designed specifically to have high responsiveness. With that in mind, four major types of tinnitus measures are reviewed, including psychoacoustic measures, self-report questionnaires concerning functional effects of tinnitus, various rating scales, and global outcome measures. Nine commonly used tinnitus questionnaires, developed in the period 1980-2000, are reviewed. Because of many similarities between tinnitus and pain, comparisons between pain and tinnitus measures are discussed, and recommendations that have been made for developing a core set of measures to evaluate treatment-related changes in pain are presented as providing a fruitful path for developing a core set of measures for tinnitus. Finally, the importance of having both immediately obtainable outcome measures (psychoacoustic, rating scales, or single global measures) and longer term measures (questionnaires covering the negative effects of tinnitus) is emphasized for further work in tinnitus outcomes assessment.
