Regarding the allegation: Staff restrained client in care resulting in multiple bruises. It was alleged staff did not implement proper Crisis Prevention Intervention (CPI) on C1 resulting in bruising. To investigate the allegation, LPA attempted interviews with four (4) clients and four (4) staff members. LPA attempted to interview C1, C2, C3, and C4 but due to their inability to validate the questions being asked, LPA terminated the interview. LPA’s interview with S1 revealed the facility is only approved for, “…standing and sitting” Crisis Prevention Intervention (CPIs) holds. When questioned if C1 had ever been restrained by staff on the floor, resulting in bruising, S1 denied the allegation. When questioned if staff ever reported an improper CPI hold being done on C1 while on the floor, S1 stated, “No”. Additionally, S1 stated if C1 were to throw themselves on the floor the staff is to, “disengage”. When questioned if C1 had been observed with bruising prior to the complaint investigation, S1 stated they were made aware of C1 having a chest bruise but stated C1 could have possibly “self-injured” themselves due to becoming “super aggressive” while staff was conducting a CPI. When questioned if the bruise may have been caused by a CPI hold, S1 stated, “No there is no reason we would ever have bruising on the chest”. When questioned if they had submitted an Unusual Incident Report (SIR) regarding C1’s bruising, S1 stated, “No, it is my bad”.

However, LPA’s interview with both S3 and S5 confirmed C1 had been placed on a CPI hold while on the floor. LPA’s interview with S5 revealed they had conducted a hold on C1 while having them on the floor. When questioned as to why this was conducted, S5 stated they were told by a former staff member (S9) it was allowed. S5 stated the hold on C1 occurred sometime in October of 2025. When questioned if the improper hold resulted in C1 to have bruises, S5 stated, “No”. When questioned if S1 was made aware of the incident, S5 stated, “Yes”. LPA’s interview with S3 correlated with S5’s interview. When questioned if the incident involving C1 was reported to S1, S3 stated, “Yes”. LPA attempted to interview S9, but they no longer work at the facility and could not be contacted.

LPA’s supplementary record review of photographic images sent to Community Care Licensing Division, (CCLD) correlated with both S3’s and S5’s interviews. LPA’s record review of said images showcased C1 to be restrained on the floor by staff members. The images showcased C1 to be laying on the floor with their back against the tile floor. Additionally, S5 is shown to be physically restraining C1 by their legs using their arms and legs to wrap themselves around C1’s legs. Another two (2) unknown staff members are shown to be controlling C1’s upper body. Additional images provided to CCLD showcased bruising on C1’s arms and chest.

Regarding the allegation: Staff hit client in care. It was alleged staff (S10 and S11) chased C3 around the facility and struck them on the forehead. To investigate the allegation, LPA attempted interviews with four (4) clients and nine (9) staff members. LPA attempted to interview C1, C2, C3, and C4 but due to their inability to validate the questions being asked, LPA terminated the interview. LPA’s interview with seven (7) of the nine (9) staff members confirmed they have not witnessed staff being offensive or inappropriate to the clients nor have they done so. LPA’s interview with S7 revealed C3 would never allow themselves to be mistreated. LPA attempted to interview S10 and S11, but they were not present during LPA’s visit. During LPA’s physical plant tour, LPA observed C3 to be in their room with staff listening to music. LPA did not observe C3 to be in distress or appear uncomfortable around staff.

Based on interviews and observations, there is not enough information to verify the allegation. Therefore, the allegation is UNSUBSTANTIATED at this time.

Regarding the allegation: Staff are in violation of clients’ personal rights. It was alleged that staff placed a sheet over C2’s head, pretended to perform an exorcism, staff members (S12 and S13) pulled C2 into their room by their arm while staff observed, recorded and laughed. To investigate the allegation, LPA attempted interviews with nine (9) staff members. LPA’s interview with all seven (7) staff members confirmed they have not witnessed staff being offensive or inappropriate to the clients nor have they done so. LPA attempted to interview S12 and S13, but they were not present during LPA’s visit.

During LPA’s visit, LPA observed C2 to be interacting with staff. LPA observed staff assisting C2 with grooming and participating in activities such as coloring and listening/singing to music. However, LPA did observe C2 to have behavioral episodes where staff were able to redirect and defuse C2’s behaviors. LPA did not observe the staff to treat or speak to C2 in derogatory or offensive manners even though C2 was verbally aggressive towards them.

Based on interviews and observations, there is not enough information to verify the allegation. Therefore, the allegation is UNSUBSTANTIATED at this time.
