Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, the frequency of sleep record will be compared six months prior to the renovations and six months after renovations have been completed. Each resident's sleep status is recorded on an hourly basis throughout the night. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Aggressive Behaviour Scale (ABS) will be compared six months prior to the renovations and six months after renovations have been completed. Behaviour items used to calculate the ABS are: verbally abusive, physically abusive, socially inappropriate/disruptive behaviour, and resists care. Indicators of behavioural symptoms are recorded as part of the MDS assessments and are based upon the frequency of the behaviour within the last 7 days. The outcome scores range from 0-12 which are indicative of the following aggressive behaviour categories: 0=non, 1-2=moderate, 3-5=severe, and 6-12=very severe. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Cognitive Performance Scale (CPS) will be compared six months prior to the renovations and six months after renovations have been completed. The CPS is based on a predictive algorithm validated against the Mini-Mental State Examination. Scores of this scale range from 0 to 6, and identify the resident's level of impairment for the following 5 elements: comatose, short-term memory, cognitive skills for daily decision-making, making self understood, and eating. A higher score indicates increased impairment in cognitive function. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Pain Scale will be compared six months prior to the renovations and six months after renovations have been completed. This was developed to examine the prevalence of pain experienced by residents in nursing homes. It has been validated against the Visual Analogue Scale and has been shown to be valid in detecting pain. Scores range 0-3 with higher scores indicating a more severe pain experience. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Falls Risks Assessment Scale will be compared six months prior to the renovations and six months after renovations have been completed.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Index of Social Engagement Scale will be compared six months prior to the renovations and six months after renovations have been completed. Scores range 0-6 with higher scores indicating a higher level of social engagement. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the PAL Tool will be compared six months prior to the renovations and six months after renovations have been completed. THE PAL Tool determines the person's current level of engagement and includes 4 activity levels: planned, exploratory, sensory, reflex. The PAL Checklist covers nine everyday activities: bathing/washing; getting dressed; eating; contact with others; group work skills; communication skills; practical activities (for example: craft, domestic chores, gardening); use of objects; and looking at a newspaper/magazine. Four descriptive statements are provided for each activity. The caregiver ticks the one that most accurately describes the individual's performance of that activity over the preceding two weeks. The number of statements selected for each level is totaled and the highest 'scoring' one indicates the individual's activity level.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Index of Depression Rating Scale will be compared six months prior to the renovations and six months after renovations have been completed. This scale suggests possible clinical depression warranting further investigation. Scores range 0-14 with a score of 3 or more may indicate a potential or actual problem with depressions. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final score of the Activities of Daily Living (ADL) Self-performance Hierarchy Scale will be compared six months prior to the renovations and six months after renovations have been completed. This scale reflects the disablement process by grouping ADL performance levels into discrete stages of loss (this is, early loss: personal hygiene; middle loss: toileting and locomotion; late loss: eating). Scores range 0-6 with higher scores indicating greater decline (progressive loss) in ADL performance. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Activities of Daily Living (ADL) Short Form Scale will be compared six months prior to the renovations and six months after renovations have been completed. This scale provides a measure of the resident's ADL self-performance status based on items that reflect stages of loss (early, middle and late loss). Scores range 0-16 with higher scores indicating more impairment of self-sufficiency in ADL Performance. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Using the Resident Assessment Inventory - Minimum Data Set 2.0 (RAI-MDS) data, final scores of the Activities of Daily Living (ADL) Long Form Scale will be compared six months prior to the renovations and six months after renovations have been completed. This scale provides measure of the resident's ability to perform ADLs. The ADL Long Form is more sensitive to clinical changes than the other ADL scales. Scores range from 0-28 with higher scores indicating more impairment of self-sufficiency in ADL performance. RAI-MDS is a standardized measurement tool that is used in long term care facilities across Canada.

Aggregated human resources data will be gathered of the number and type of worker's compensation board claims of staff working on the special care unit from pre- to post-renovation.

Aggregated human resources data will be gathered of the total number of hours and average number of hours when staff have been absent from work due to illness from pre- to post-renovation

Aggregated human resources data will be gathered of the total number of hours staff have taken a leave of absence for any reason from pre- to post-renovation.

Aggregated human resources data will be gathered on the total number of staff who worked on the special care unit prior to the renovations and were still working on the unit at post-renovation.

Aggregated human resources data will be gathered on the total number of staff who worked on the special care unit prior to the renovations but were no longer working on the unit at post-renovation.

Quality of Life in Late stage Dementia (QUALID) questionnaire total score will be compared before and after renovations. The QUALID is completed by family who have visited a resident at least three of the last seven days. This is an 11-item interview that asks a family member or caregiver to rate how often a specific resident exhibits behaviours associated with quality of life (e.g., smiling, enjoying a meal). A 5-point scale captures the frequency of each item (total score ranging from 11 to 55). Lower scores reflected a higher quality of life (QOL). This interview takes 5-10 minutes to complete for each resident for whom we have consent/assent.

Dementia Care Mapping (DCM) involves observing residents over several hours. The goal of this assessment is to collect in-depth data regarding resident's behaviours and use of space/time during a discrete time period. Mapping takes place using a designated instrument by a certified mapper, and in communal care and living spaces. One to twenty four different domains are tracked that can be said to account for a high level or a low level of well-being or quality of life. Observations of family members may also occur for those who have provided consent. Observational data will be entered into a computer program that provides profiles of residents' mood, engagement and well-being. This provides a useful index of the relative well-being or detriments that affect an individual in a given space and given specific relational and care activities.

Key staff informants will participate in a walk-through interview where the informant and investigator walk through the unit and discuss the physical space. This is a qualitative interview.

Measures will be taken of dry bulb temperature at pre- and post-renovations. Optimum comfort for sedentary work is between 20°C and 26°C, depending on the time of year and clothing worn.

Measures will be taken of air speed at pre- and post-renovations. For an all air systems, air velocity (speed) should be typically 20 fpm (0.1m/sec) to 40 fpm (.2 m/sec) to be experienced by the occupant. 40 fpm would be experienced in a laboratory environment whereas 15-20 fpm would be typical for an office space.
