Objective: The objective was to describe end-of-life treatment decisions for patients dying with dementia in various stages of dementia in long-term care facilities in the Netherlands with elderly care physicians responsible for treatment and care.Methods: We present data collected in the nationally representative Dutch End of Life in Dementia study (2007-2011). Within 2 weeks after death, 103 physicians completed questionnaires about the last phase of life in 330 residents with dementia who resided in 1 of 34 participating long-term care facilities. We used descriptive statistics.Results: Advance directives were rare (4.9%). A minority was hospitalized (8.0%) in the last month (mainly for fractures) or received antibiotics (24.2%) in the last week (mainly for pneumonia). Four residents received tube feeding or rehydration therapy in the last week. In almost half of the residents (42.3%), decisions were made not to start potentially life-prolonging treatment such as hospital transfer and artificial nutrition and hydration. In more than half of the residents (53.7%), decisions were made to withdraw potentially life-prolonging treatment such as artificial nutrition and hydration and medication. Antibiotics were more frequently prescribed for residents with less advanced dementia, but otherwise there were no differences in treatment decisions between residents with advanced and less advanced dementia.Conclusions: Physicians often withhold potentially burdensome life-prolonging treatment in nursing home residents in all stages of dementia in the Netherlands. This suggests that the physicians feel that a palliative care approach is appropriate at the end of life in dementia in long-term care. Copyright © 2016 John Wiley & Sons, Ltd.

Background: The management of pain in long-term care (LTC) residents with dementia is complex. A prospective exploratory study was conducted to describe the course of pain and pain management strategies following a guideline-based pain assessment procedure in LTC residents with pain and dementia.Measures: Pain observations with the Mobilization Observation Behaviour Intensity Dementia (MOBID-2) Pain Scale, a review of the electronic patient file and pharmacy files and physical examination of LTC residents with pain and dementia.Intervention: Communication of the assessment results to the attending physician including guideline-based treatment recommendations.Outcomes: After three months, complete follow-up data were obtained for 64 residents. Pain intensity was significantly reduced (P < 0.001). The proportion of residents with persistent pain was 58% and the total number of analgesic prescriptions did not change significantly.Conclusions: There is room for improvement regarding pain management in LTC residents with pain and dementia, and performance feedback seems a promising strategy to explore further.

Physician burnout is a critical factor influencing the quality of care delivered in various healthcare settings. Although the prevalence and consequences of burnout have been well documented for physicians in various jurisdictions, no studies to date have reported on burnout in the postacute and long-term care setting. In this exploratory study, we sought to quantify the prevalence of burnout among 3 cohorts of physicians, each practicing in nursing homes in the United States (US), Canada, or The Netherlands. International comparisons were solicited to highlight cultural and health system factors potentially impacting burnout levels. Using standard survey techniques, a total of 721 physicians were solicited to participate (Canada 393; US 110; The Netherlands 218). Physicians agreeing to participate were asked to complete the “Maslach Burnout Inventory” using the Survey Monkey platform. A total of 118 surveys were completed from The Netherlands, 59 from Canada, and 65 from the US for response rates of 54%, 15%, and 59%, respectively. While US physicians demonstrated more negative scores in the emotional exhaustion subscale compared with their counterparts in Canada and The Netherlands, there were no meaningful differences on the depersonalization and personal accomplishments subscales. Factors explaining these differences are explored as well as approaches to future research on physician burnout in postacute and long-term care. [ABSTRACT FROM AUTHOR]

Objectives Burdensome symptoms frequently develop as part of the dementia trajectory and influence quality of life. We explore the course of symptoms and their treatment during nursing home stay to help target adequate symptom management. Design Data were collected as part of the Dutch End of Life in Dementia study, a longitudinal observational study with up to 3.5 years of follow-up. Physicians performed assessments at baseline, semiannually, and shortly after death of pain, agitation, shortness of breath, and treatment provided for these symptoms. Setting Long-term care facilities (28) in the Netherlands. Participants Newly admitted nursing home residents (372) in variable stages of dementia. Measurements We described prevalence and course of symptoms, and treatment provided for these symptoms. We used generalized estimating equations to evaluate the longitudinal change in symptoms and their treatment, and the associations between the symptoms of pain and agitation, as well as between stage of dementia and symptoms. Results Pain was common (varying from 47% to 68% across the semiannual assessments) and frequently persistent (36%–41% of all residents); it increased to 78% in the last week of life. Agitation was the most common symptom (57%–71%), and also frequently persistent (39%–53%), yet it decreased to 35% in the last week of life. Shortness of breath was less common (16%–26%), but it increased to 52% at the end of life. Pain was not significantly associated with agitation. Advanced dementia was associated with more pain only. Treatment changed in particular at the end of life. Pain was treated mostly with acetaminophen (34%–52%), and at the end of life with parenteral opioids (44%). Agitation was mostly treated nonpharmacologically (78%–92%), and at the end of life anxiolytics were the most frequently prescribed treatment (62%). Overall, aerosolized bronchodilators were the most frequently prescribed treatment for shortness of breath (29%–67%), but at the end of life, this was morphine (69%). Conclusion Pain and agitation were common and frequently persisted in residents with dementia during nursing home stay, but symptom management intensified only at the end of life. Symptom control may be suboptimal from admission, and a stronger focus on symptom control is needed at an earlier stage than the end of life. [ABSTRACT FROM AUTHOR]

Objectives The objective of this study is to explore factors that elucidate reasons for psychotropic drug (PD) prescription for neuropsychiatric symptoms (NPS) in nursing home (NH) residents with dementia. Design A qualitative study using a grounded theory approach. Setting Twelve NHs in The Netherlands. Participants Fifteen physicians and 14 nurses. Measurements Individual, face-to-face, in-depth semistructured interviews. Interviews were audio recorded, transcribed, and qualitatively analyzed using Atlas.ti. Results The qualitative analysis revealed 4 emerging themes with factors either or both enhancing or limiting PD prescription, which we used to develop a conceptual framework. First, the mindset of physicians and nurses toward NPS and PDs appeared to contribute. Second, inadequate knowledge of and experience with NPS and limited people skills of nurses may induce PD prescription. Also, knowledge of effectiveness and side effects of PDs from education, literature, and guidelines, and previous personal experiences was considered relevant. Third, effective communication and cooperation between professionals and with family may improve the appropriateness of PD prescription. Fourth, external factors including staffing issues, nursing home setting, access to consultants, national and local policies, and zeitgeist were considered to affect PD prescription. Conclusion We have developed a conceptual framework explaining how different factors influence PD prescription. This provides opportunities for improving PD prescription in NH residents with dementia. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: To determine the prevalence of antibiotic resistance and multiresistance of Escherichia coli and Staphylococcus aureus in nursing homes and to determine which factors are associated with this prevalence. Design: Cohort study. Setting: Nursing homes. Participants: Residents of long-stay somatic care wards and rehabilitation patients were recruited from five nursing homes and two rehabilitation wards in hospitals in the central region of the Netherlands. Measurements: From each included patient, an anal swab was analyzed for E. coli and its antibiotic susceptibility and extended spectrum β-lactamase-producing Enterobacteriaceae. Nasal swabs were analyzed for S. aureus and its susceptibility, including methicillin-resistant S. aureus (MRSA). Associations were determined between resistance of E. coli to amoxicillin/co-amoxiclav and recent use (previous 6 months) of these antibiotics, hospital admission (previous 3 months), and presence of a urinary catheter. Results: A total of 125 patients were included in the study. The resistance and intermediate susceptibility of E. coli varied from 4% (ceftriaxone) to 43% (amoxicillin). Extended spectrum β-lactamase-producing Enterobacteriaceae were found in 6% of the patients. Amoxicillin and/or co-amoxiclav users were significantly more resistant to these antibiotics (69%) than nonusers (38%). No associations were found between amoxicillin and/or co-amoxiclav resistance and hospital admission or presence of a urine catheter. The resistance of S. aureus varied from 0% to 69% (penicillin). No MRSA was found. The ciprofloxacin resistance in E. coli and S. aureus was 14% and 39%, respectively. Conclusion: The prevalence of antibiotic-resistant E. coli and S. aureus in nursing homes was considerably high in this study, although no MRSA was found. This may lead to failing of empiric therapy of infections in patients in nursing homes. In particular, the high resistance to ciprofloxacin may make empiric quinolone therapy unreliable. Antibiotic use was associated with antibiotic resistance of E. coli. Therefore, antibiotic use should be restricted as much as possible. Analysis of risk factors for antibiotic resistance should be extended to be able to prevent further development of antibiotic resistance in nursing homes. [Copyright &y& Elsevier]

Objective To determine the impact of depression and anxiety on well being, disability and use of health care services among nursing patients. Methods The study-population consisted of 350 elderly nursing home patients from 14 nursing homes in the Netherlands. Well being, disability, use of health care services (i.e. assistance in ADL, paramedical care, number of medications) and depression and anxiety and other relevant characteristics (gender, age, education, marital status, urbanization, cognition, morbidity, social support) were measured cross-sectionally. Associations of well being, disability and use of health care services with independent baseline characteristics were assessed with bivariate and with multivariate analyses. Results Presence of depression and/or anxiety was associated with significantly less well being, but not with more disability. Presence of depression and/or anxiety was also significantly associated with four of the seven indicators of health care service use measured in this study: less assistance in ADL, more consultation of medical specialists, a higher mean number of medications and more use of antidepressants. Conclusion Presence of depression and/or anxiety has a statistically and clinically significant negative impact on well being, but not on disability. Future studies should focus on interventions for improving the detection, diagnosis and treatment of depression and/or anxiety in the nursing home. Copyright © 2006 John Wiley & Sons, Ltd.

Medical providers in long-term care (LTC) use a unique skillset in delivering comprehensive resident care. Publicly reported quality measures (QMs) do not directly emphasize medical provider competency and their role in care. The impact of providers is understudied and to a large extent, unknown. Our objective was to define, test, and validate QMs to pragmatically measure the practice-based quality of medical providers in a pilot study. We included 7 North American LTC homes with data from practicing medical providers for LTC residents. We engaged in a 4-phased approach. In phase 1, experts rated 95 candidate QMs using 5 pragmatic-focused criteria in a RAND-modified Delphi process. Phase 2 involved specifying 37 QMs for collection (4 QMs were dropped during pilot testing). We created an abstraction manual and data collection tool for all QMs. Phase 3 involved a retrospective chart review in 7 LTC homes on 33 QMs with trained data abstractors. Data were sufficient to analyze performance for 26 QMs. Lastly, in phase 4 results and psychometric properties were reviewed with an expert panel. They ranked the tested measures for validity and feasibility for use by a nonphysician auditor to evaluate medical provider performance based on medical record review. In total, we examined data from 343 resident charts from 7 LTC homes and 49 providers. Our process yielded 10 QMs as being specified for measurement, feasible to collect, and had good test performance. This is the only study to systematically identify a subset of QMs for feasible collection from the medical record by various data collectors. This pragmatic approach to measuring practice-based quality and quantifying select medical provider competencies allows for the evaluation of individual and facility-level performance and facilitates quality improvement initiatives. Future work should perform broader testing and validate and refine operationalized QMs. [ABSTRACT FROM AUTHOR]

Objectives Physician treatment orders (PTOs) prevent burdensome unnecessary medical treatment of frail nursing home patients. The aim was to determine the prevalence of PTOs and time duration between nursing home admittance and PTO completion. Design Population-based, retrospective cohort study. Setting Nursing homes across the Netherlands. Data Collection Digital medical records of patients who subsequently were submitted to 14 Dutch nursing homes across The Netherlands were studied between 2010 and 2013. The prevalence's of do-resuscitate, do-not-resuscitate, life-sustaining, and palliative care PTOs and the time intervals between nursing home admittance and documentation of PTOs were measured. Information regarding demographic patient characteristics, type of nursing home ward, and mention of a discussion of PTOs with the patient or caregivers was obtained. Results Eighty-two percent of the nursing home patients received a PTO regarding resuscitation, life-sustaining, or palliative care treatment. Twenty-four percent of the patients received a do-resuscitation PTO, 55% received a do-not-resuscitate PTO, 44% a life-sustaining PTO, and 16% a palliative care PTO. The median duration between nursing home admittance and documentation of the first PTO was 1 day. Most nursing home patients had PTOs within 1 week after admittance. Conclusion A minority (18%) of Dutch nursing home patients has no documented PTOs during their nursing home stay, which could have negative effects on end-of-life care of nursing home residents.

The researchers aimed to (1) explore the occurrence of psychological resilience in the face of a major life stressor and conflict in older residents of long-term care facilities (LTCFs), and (2) identify factors associated with resilience in this population. Longitudinal cohort study using the Dutch InterRAI-LTCF cohort. Older residents (≥60 years old) of 21 LTCFs in the Netherlands. The researchers selected 2 samples of residents who had at least 2 assessments surrounding (1) an incident major life stressor, or (2) incident conflict with other resident or staff. A resilient outcome was operationalized as not having clinically meaningful mood symptoms at the post-stressor assessment and equal or fewer mood symptoms at the post-stressor relative to the pre-stressor assessment. The researchers used 2 resilience outcomes per stressor: 1 based on observer-reported mood symptoms and 1 based on self-reported mood symptoms. The most important factors from among 21 potential resilience factors for each of the 4 operationalizations of resilience were identified using a backward selection procedure with 2-level generalized estimating equations analyses. Forty-eight percent and 50% of residents were resilient in the face of a major life stressor, based on observer-reported (n = 248) and self-reported (n = 211) mood, respectively. In the face of conflict, 26% and 51% of the residents demonstrated resilience, based on the observer-reported (n = 246) and self-reported (n = 183) mood, respectively. Better cognitive functioning, a strong and supportive relationship with family, participation in social activities, and better self-reported health were most strongly associated with resilience in the face of a major life stressor. Better communicative functioning, absence of psychiatric diagnoses, a strong and supportive relationship with family, not being lonely, social engagement, and not reminiscing about life were most strongly associated with resilience in the face of conflict. Factors with a social aspect appear to be particularly important to psychological resilience in older LTCF residents, and provide a potential target for intervention in the LTCF setting.

Abstract: Objectives: The Grip on Challenging Behavior care program was developed using the current guidelines and models on managing challenging behavior in dementia in nursing homes. It was hypothesized that the use of the care program would lead to a decrease in challenging behavior and in the prescription of psychoactive drugs without increase in use of restraints. Design: A randomized controlled trial was undertaken using a stepped-wedge design to implement the care program and to evaluate the effects. An assessment of challenging behavior and psychoactive medication was undertaken every 4 months on all participating units followed by the introduction of the care program in a group of 3 to 4 units. A total of 6 time assessments took place over 20 months. Setting: Seventeen dementia special care units of different nursing homes. Participants: A total of 659 residents of dementia special care units. All residents with dementia on the unit were included. Units were assigned by random allocation software to 1 of 5 groups with different starting points for the implementation of the care program. Intervention: A care program consisting of various assessment procedures and tools, which ensure a multidisciplinary approach and which structure the process of managing challenging behavior in dementia. Measurements: Challenging behavior was measured using the Cohen-Mansfield Agitation Inventory (CMAI) and the Neuropsychiatric Inventory. Research assistants (blinded for intervention status of the unit) interviewed nurses on the units about challenging behavior. Data on psychoactive drugs and restraints were retrieved from resident charts. Results: A total of 2292 assessments took place involving 659 residents (1126 control measurements, 1166 intervention measurements). The group of residents who remained in the intervention condition compared with the group in the control condition differed significantly in the CMAI change scores between successive assessments [–2.4 CMAI points, 95% confidence interval (CI) –4.3 to –0.6]. No significant effects were found for the control-to-intervention group compared with the group who remained in the control group (0.0 CMAI points, 95% CI –2.3 to 2.4). Significant effects were found on 5 of the 12 Neuropsychiatric Inventory items and on the use of antipsychotics (odds ratio 0.54, 95% CI 0.37– 0.80) and antidepressants (odds ratio 0.65, 95% CI 0.44–0.94). No effect on use of restraints was observed. Conclusions: The Grip on Challenging behavior program was able to diminish some forms of challenging behavior and the use of psychoactive drugs.

We aimed to explore the effects of the Dutch COVID-19 lockdown (March 20–May 25, 2020) on mood, behavior, and social and cognitive functioning of older residents of long-term care facilities (LTCFs) prospectively. Mixed methods: historically controlled longitudinal cohort study and focus groups. Residents of Dutch LTCFs. Residents who were assessed during and prior to the lockdown were compared to residents of the same wards with 2 assessments prior to the lockdown. We used mixed models and generalized estimating equation analyses to explore differences in changes in mood, withdrawal and aggressive behavior, loneliness and conflict, and cognition and delirium. We also explored whether the effect of the lockdown differed for different subgroups. In 2 online focus groups, LTCF care professionals, ranging from care staff to physicians, reflected on their experiences of the effect of the lockdown and the cohort study results. The lockdown group of 298 residents was compared to the control group of 625 residents. Self-reported mood symptoms showed a slightly greater increase during the lockdown. During the first half of the lockdown, the level of conflict with other residents decreased whereas it increased in the control group. The subgroup with moderate-severe cognitive impairment showed a decrease in withdrawal during the lockdown, whereas the group with no-mild cognitive impairment showed a statistically nonsignificant relative increase. Professionals described great individual variation in the effects of the lockdown on residents. Facilities attempted to preserve the experienced positive effects, for example, by promoting tranquility in shared rooms and continuing to organize individualized ward-based activities. We did not find clinically relevant negative effects of the lockdown on mood, behavior, and social and cognitive functioning in older residents of LTCFs at the group level. Possibly, staff mitigated the negative effects at the group level. Meanwhile, they learned lessons that they continue to apply to enhance resident well-being. [ABSTRACT FROM AUTHOR]

Objective: Pain is a frequent long-term consequence of stroke, but its relation to emotional and social well-being is poorly studied in stroke populations. We aimed to identify the prevalence of substantial pain among institutionalized stroke patients and to explore its relation to emotional distress (ED) and low social engagement (SE).Methods: In a cross-sectional design, we collected data of 274 chronic stroke patients in Dutch nursing homes. Observation lists were filled out in structured interviews with qualified nurse assistants who knew the residents well. Pain and SE were measured with the Resident Assessment Instrument for Long-term Care Facilities, and ED was measured with the Neuropsychiatric Inventory Questionnaire (NPIQ).Results: Substantial pain was present in 28% of the residents, mostly located in the affected body side (68%). Multilevel regression analyses revealed that this pain was independently related to a 60% increase in NPIQ score (β 3.18 [1.84-4.53]) and to clinically relevant symptoms of delusions (odds ratio [OR] 8.45 [1.82-39.05]), agitation/aggression (OR 3.82 [1.76-8.29]), depression (OR 3.49 [1.75-6.98]), and anxiety (OR 2.32 [1.08-4.97]). Substantial pain was associated with low SE when adjusted for clinical covariates (OR 4.25 [1.72-10.53]), but only in residents with no/mild or severe cognitive impairment. This relation disappeared when additionally corrected for NPIQ score (OR 1.95 [0.71-5.39]).Conclusions: Pain is a serious and multidimensional problem among institutionalized stroke patients. It is related to increased ED, which in turn can be a pathway to low SE as an indicator of social vulnerability. Future research should reveal how pain management in nursing homes can be tailored to the needs of this patient group. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: In view of the development of an integrated care and treatment program for institutionalized stroke patients tailored to their needs, we aimed to explore their status of functioning in the physical, cognitive, emotional, communicative and social domains. In addition, we explored the relation between status of functioning and stroke characteristics. Design: A cross-sectional, observational study. Setting: Dutch nursing homes (NHs). Participants: Residents with stroke as main diagnosis for NH-admission, who experienced a stroke ≥3 months ago and stayed ≥1 month in a long term care ward. Measurements: Attending physicians provided information about stroke subtype, stroke location and time post-stroke. Status of functioning was measured through an observation list comprising the Barthel Index, the Neuropsychiatric Inventory Questionnaire, and sections of the Resident Assessment Instrument for Long-Term Care Facilities. The list was filled out in a structured interview with a qualified nurse assistant who knew the resident well. Results: We included 274 residents (mean age 76.6, 58.4% female). The stroke that caused NH-dependency was in 81.3% ischemic, and in 49.8% right-sided. Median time post-stroke was 47 months; 90.9% of the residents were severely dependent in basic activities of daily living and 58% were in pain. Nearly half of the residents showed moderate (24.4%) or severe (23%) cognitive impairment. Irritability (52.9%), depressive symptoms (52.6%) and apathy (34.3%) occurred as the most frequent neuropsychiatric symptoms; 27.7% had a poor ability to express themselves and 30.3% had a low social engagement. We found more severe cognitive impairment, agitation/aggression and poor expression in left-sided strokes, more nighttime behavioral disturbances and delusions in right-sided strokes, and lower social engagement in residents with the largest time-interval post-stroke. Conclusion: This study among institutionalized stroke patients in Dutch NHs revealed very high prevalence of impairments on all domains of functioning, above the well-known severe disabilities in basic activities of daily living. The monitoring and management of both pain and neuropsychiatric symptoms should be key elements in an integrated care and treatment program. [Copyright &y& Elsevier]

Abstract The initiative described here aims to identify quality indicators (QIs) germane to the international practice of primary care providers (PCP) in post-acute and long-term care in order to demonstrate the added value of medical providers in nursing homes (NHs). A 7-member international team identified and adapted existing QIs to the AMDA competencies for medical providers. QI sources included the ACOVE 3 Quality Indicators (2007), NH Quality Indicators (2004), NH Residential Care Quality Indicators (2002), and AGS Choosing Wisely (2014). We recruited a technical expert panel (TEP) consisting of 11 panelists from the US, Canada, and the European Union, selected for their knowledge and leadership in post-acute and long-term care. The TEP, using a RAND Modified Delphi approach, provided pre-meeting ratings, discussed items in-person for clarification, and re-rated items following discussion. When panelists rated more than 1 option for a particular QI as valid and feasible, the most stringent option was selected for inclusion in the final candidate set of QIs. Panelists confidentially rated an initial 103 items on validity and feasibility of implementation. During the meeting, panelists added 18 QIs and modified 18. In post-meeting analysis, we eliminated 7 QIs rated not valid and 9 QIs for which a more stringent QI was rated valid and feasible. This resulted in a final set of 97 QIs rated valid and feasible and 8 rated valid but not feasible. This set of QIs for PCPs in the NH identified practices in which provider engagement adds value through expertise in geriatric syndromes, employing evidence-based practice, advocating for residents, delivering person-centered care, facilitating advance care planning, and communicating effectively to coordinate care. Next steps include pilot testing and evaluating the association between adherence to QIs, PCP staffing models, and better outcomes. [ABSTRACT FROM AUTHOR]

Background: Current guidelines and theories on the origin of challenging behaviour in dementia indicate that a structured multidisciplinary approach to its management is necessary. In the Grip on Challenging Behaviour study, a care programme was developed to improve the management of challenging behaviour. Method: In developing the care programme, the overlapping parts of dementia care guidelines were supplemented with discipline-specific parts. Three meetings with experts were arranged to further develop the structure of the care programme and to ensure a good fit with practice. Results: The care programme consists of four steps: detection, analysis, treatment, and evaluation. For each step, forms were developed to guide and structure the process and assign responsibilities for each discipline. As well as a description of the development and the content of the care programme, this paper presents two case studies in which the programme was used. Conclusion: The Grip on Challenging Behaviour care programme provides a way for dementia special care units to manage challenging behaviour in a structured way and with a multidisciplinary approach making use of their own resources.

Abstract: Background: A multidisciplinary, evidence-based care program to improve the management of depression in nursing home residents was implemented and tested using a stepped-wedge design in 23 nursing homes (NHs): “Act in case of Depression” (AiD). Objective: Before effect analyses, to evaluate AiD process data on sampling quality (recruitment and randomization, reach) and intervention quality (relevance and feasibility, extent to which AiD was performed), which can be used for understanding internal and external validity. In this article, a model is presented that divides process evaluation data into first- and second-order process data. Methods: Qualitative and quantitative data based on personal files of residents, interviews of nursing home professionals, and a research database were analyzed according to the following process evaluation components: sampling quality and intervention quality. Setting: Nursing home. Results: The pattern of residents’ informed consent rates differed for dementia special care units and somatic units during the study. The nursing home staff was satisfied with the AiD program and reported that the program was feasible and relevant. With the exception of the first screening step (nursing staff members using a short observer-based depression scale), AiD components were not performed fully by NH staff as prescribed in the AiD protocol. Conclusion: Although NH staff found the program relevant and feasible and was satisfied with the program content, individual AiD components may have different feasibility. The results on sampling quality implied that statistical analyses of AiD effectiveness should account for the type of unit, whereas the findings on intervention quality implied that, next to the type of unit, analyses should account for the extent to which individual AiD program components were performed. In general, our first-order process data evaluation confirmed internal and external validity of the AiD trial, and this evaluation enabled further statistical fine tuning. The importance of evaluating the first-order process data before executing statistical effect analyses is thus underlined. [Copyright &y& Elsevier]
