OAR 333-600-0030: Need Methodology

The method for estimating the needed number of beds or service capacity for each type of chemical dependency treatment setting consists of the following steps: (1) For a service which is designed to serve persons in the present service area of a given hospital or hospitals, determine the hospital service area according to OAR 333-590-0040. (2) For a service with a geographical targeting different from section (1) of this rule, evaluate the proposed service area according to OAR 333-600-0020(7) and (8), considering also the likelihood of contractual commitments to serve specific groups of potential clients. (3) Determine the estimated population for the service area for the calendar year five years beyond the letter of intent year of the application. (4) Obtain the estimated number of problem drinkers in the service area in five years for adults by calculating seven percent of the service area’s population age 19 and over; and for adolescents by calculating 19 percent of the 12–18 year old population. (5) Determine the estimated number of problem drinkers who will seek treatment in a one-year period, by calculating 15 percent of the number derived in section (4) of this rule. (6) Determine the specific levels and kinds of services required to meet the need, for all services other than outpatient: Multiply the number derived in section (5) of this rule by the beds per contact figure from Table 1, for the particular type of chemical dependency treatment service requested and divide by .90 to allow for occupancy variations. For outpatient service, utilize the service ratios figures in Table 1: Table 1 Chemical Dependency Beds per Service Treatment Services Contact Ratios Medical facility-based detoxification .0014 1 Nonmedical facility-based detoxification .0127 9 Inpatient hospital services .0072 5 Residential treatment, 24-hour .00689 49 Residential treatment, partial .00641 46 (day, night, or weekend) Rehabilitation (long-term) .00336 24 Residential maintenance care .01160 83 Outpatient care --- 781 (7) Determine the number of existing beds or service capacity for each of the service elements in the service area. (8) Subtract the level of existing services determined in section (7) of this rule from the projected need for services derived in section (6) of this rule. (9) Evaluate the estimated need against the principles in OAR 333-600-0020 to determine need for proposed service. (10) Although separate bed need standards are not established for specialty types of chemical dependency beds, the division recognizes that chemical dependency beds could be used to deliver various subspecialty services, such as adolescent or geriatric chemical dependency programs, and programs for patients with both a mental illness and a chemical dependency problem (“dual diagnosis” patients).
