Regarding the allegation: Staff dispensed medication that was not prescribed to the client. It was alleged that S2 had given C1 medication that was not prescribed. To investigate the allegation, LPA attempted interviews with four (4) clients and fourteen (14) staff members. LPA attempted to interview C1-C3 but due to their various medical diagnosis, they could not be interviewed. LPA terminated the interviews. LPA attempted to interview C4, but they were not present during LPA’s initial visit. LPA’s interview with seven (7) of the fourteen (14) staff members stated they have not witnessed any staff members to give C1 or any other client’s medication that is not prescribed to them. LPA attempted to interview S2 but S2 is currently on a leave of absence and could not be contacted. LPA attempted to contact S12-S14 but was unsuccessful.

During LPA’s physical plant tour, LPA observed the medication to be kept locked in a kitchen cabinet. LPA observed all client’s medication to be kept stored in their own individualized containers labeled with their corresponding information. LPA observed C1’s Medication Administration Records (MARS) to not contain the said medication per the Reporting Party (RP).

Based on interviews and record review, 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 client’s personal rights. It was alleged that staff have violated C1’s personal rights such as but not limited to: being disrespectful, mocking and reframing from allowing C1 to receive telephone calls. To investigate the allegation, LPA attempted interviews with four (4) clients and ten (10) staff members. LPA’s interview with all staff members revealed that they have not, nor witnessed staff members violating C1’s personal rights. When questioned regarding the alleged photo that was displayed to offend C1, nine (9) of the ten (10) staff members denied ever witnessing such photo. LPA’s interview with an additional Co-Reporting Party claimed to have seen the photo in question but did not witness who may have placed said photo.

LPA’s interview with S1 revealed that C1 has various behavioral tendencies that can lead to other medical episodes. Due to these episodes, S1 has informed C1’s Case Worker from North Los Angeles Regional Center (NLARC) of such incidents and how staff have responded to help defuse the situations for the health and safety of C1. LPA’s interview with C1’s Consumer Service Coordinator (CSC) confirmed that they have been made aware of such situations resulting in C1’s Individual Program Plan (IPP) to be updated reflecting such incidents. LPAs record review of C1’s IPP confirmed such exhibited behaviors due to isolated incidents involving C1 notated. (continue to LIC 9099-C)

During LPA’s physical plant tour, LPA observed C1’s bedroom to be neat, clean and organized. LPA did not observe any offensive photographs to be displayed within the facility. LPA observed C1 interacting with various staff members. LPA observed C1 to seem at ease with staff members and did not display any behaviors indicating them not to be so. LPA observed C1 to be coloring, watching television and taking a nap throughout their initial visit.

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

Regarding the allegation: Staff did not seek timely medical attention for the client. It was alleged that staff failed to seek medical attention for C1 in an appropriate timeframe. To investigate the allegation, LPA attempted interviews with four (4) clients and ten (10) staff members. LPA’s interview with all staff members confirmed that all clients are attended to in a timely manner for any medical situations. LPA’s record review of C1’s medical visitations confirmed that C1 was seen on 10/26/2025. Further record review of the facility’s Unusual Incident/Injury Report (SIRs) confirmed the facility had self-reported C1’s medical visit to Community Care Licensing Division (CCLD) on 10/28/2025. Additional record review of the facility’s SIRs revealed that C1’s behaviors and medical situations have been reported between the dates of 4/8/2025 to 12/15/2025.

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

Regarding the allegation: Licensee did not maintain staffing ratios as required. It was alleged that the facility has not met their required staff ratios. To investigate the allegation, LPA conducted an interview with one (1) staff member. LPA’s interview with S1 revealed that three (3) of the four (4) clients require a 2:1 staff ratio. S1 stated the facility’s staff schedule is posted along the common area for review. On 12/01/2005, LPA spoke with a staff member from NLARC where it was confirmed that three (3) of the four (4) clients require a 2:1 staff ratio. LPA’s record review of the staff schedule pertaining to each client revealed that C2’s staff ratio did not reflect the required 2 to 1 staff ratio. However, on 1/12/2026, LPA received information from C2’s CSC where it was revealed that the facility is in the process of phasing out to a one (1) to one (1) staffing ratio for C2.
