The term "hospitals" as used in this act shall include hospitals, sanatoria and other institutions operated for the purposes mentioned in section 2 of this act.

     Hereafter it shall be competent and lawful for the board of supervisors of any county in this state now or hereafter having a population of more than 100,000 as determined by the last federal decennial census or by any federal decennial census hereafter taken, to acquire, own, construct, establish, maintain and operate a hospital for the treatment of persons suffering from contagious and infectious diseases and for the treatment of indigent persons suffering from any physical ailment or impairment, and may contain a psychiatric ward for mentally ill patients, both non-indigent and indigent, provided that such a ward has been approved by the state department of mental health.

In no case shall a tax for the original acquisition and construction exceed in any 1 year 1 mill on each dollar of the assessed valuation of said county. If deemed expedient by said board, moneys for acquisition or construction purposes hereunder may be raised by taxation during successive years, and said board of supervisors may also appropriate from any unexpended moneys in the general fund of the county for such purposes. All money raised by taxation within the county, and all moneys appropriated by said board of supervisors for such purposes, shall constitute a special fund for acquisition or construction and equipment of the hospital. Moneys raised by taxation or appropriated by the board of supervisors for acquisition or construction purposes, and subsequently found not to be needed therefor, may be used to defray the expenses of operation and maintenance.

     A board of trustees for the management of any hospital created hereunder shall be appointed by the board of supervisors of the county in which such hospital is to be acquired, maintained and operated. Said trustees shall be residents and freeholders of the county and may be members of the board of supervisors. Said board shall consist of 5 members to be appointed for terms of 3 years each: Provided, That of the members first appointed 1 shall be appointed for a term of 3 years, 2 for terms of 2 years each, and 2 for terms of 1 year each.

Each such trustee shall file with the county clerk the constitutional oath of office. It shall be the duty of said board of trustees to cooperate and advise with the state health commissioner and with the board of supervisors of the county, or with any committee selected thereby, in the equipping of the hospital.

In all cases where the cost of construction or the purchasing of equipment exceeds the sum of $500.00, bids shall be advertised for in 1 or more newspapers published or circulated within the county concerned not less than 2 weeks prior to the date when bids are to be received. The board of supervisors may adopt reasonable rules and regulations concerning the manner of advertising for bids and the letting of contracts. In all cases the right to reject any and all bids presented shall be reserved. Each contract let hereunder shall provide, that the work shall be done or the material purchased subject to the approval of the board of supervisors of the county or by any committee of said board of supervisors selected for that purpose.

     Subject to the provisions of this act each such board of trustees shall operate the hospital or institution under its charge and may employ, within appropriations made by the board of supervisors of the county, a medical superintendent, physicians, nurses, and such other employees as may be necessary. The medical staff of the hospital shall with the approval of the board of trustees adopt rules, regulations and policies governing the professional work of the hospital and the eligibility and qualifications of its medical staff, which may conform, as nearly as practicable, to the applicable standards recommended by the American College of Surgeons. Money to defray the expenses of maintenance and operation subject to audit as in section 8 provided shall be paid by the county treasurer having such funds in its custody on the warrant of the president of the board of trustees of the hospital, countersigned by the secretary.

     If the facilities of the hospital or institution will permit, the board of trustees, in its discretion, may accept other persons afflicted with contagious or infectious diseases and other indigent persons suffering from any physical ailment or impairment, and for temporary detention of mentally ill patients, both non-indigent and indigent, and upon such terms and conditions as may be fixed by the board of supervisors of the county.

     The board of trustees may make regulations governing the conduct of patients and may exclude any person or persons wilfully violating such regulations.

     No member of the board of trustees of any hospital established or maintained hereunder shall be entitled to receive compensation for his services. Any such trustee, however, shall be reimbursed on account of any expense necessarily incurred by him in the performance of his official duties. All claims against the hospital shall be submitted to the board of trustees thereof, and, if approved, shall be subject to audit by the board of supervisors, and shall be paid in the manner other claims against the county are paid. Any vacancy occurring on the board of trustees shall be filled for the remainder of the term by the board of supervisors of the county. Any trustee may be summarily removed by the board of supervisors for misfeasance or malfeasance in office or for failure to follow any direction or resolution of the board of supervisors or any committee of said board of supervisors empowered to make such direction or resolution.

     Any person or persons, firm, organization, corporation or society may make donations of money, personal property or real estate for the benefit of such hospital, and shall have the right to vest title of the property so donated in the county. Such gifts, when accepted, shall be used in accordance with the terms of the deed, gift, devise or bequest of such property, if any; otherwise, the same shall be used in such manner as the board of supervisors shall direct for the benefit of said hospital or institution.

     Prior to the regular October session of the board of supervisors in each year, it shall be the duty of the board of trustees of the hospital or institution to make and present to the board a full and detailed report of the operations during the preceding year and of the receipts and disbursements. Said board of trustees shall present to said board of supervisors any information said board of supervisors may request concerning said hospital or institution. Said board of trustees shall present to the board of supervisors an estimate of the funds necessary to be raised in such county for the ensuing year. Thereupon, the board of supervisors, subject to the provisions of this act, shall vote such amount as it shall deem necessary to be raised by taxation. No moneys shall be expended by the board of trustees, except as appropriated by the board of supervisors. In case it is deemed expedient by any board of supervisors to raise in any 1 year, either for acquisition, construction, maintenance or operation purposes, an amount in excess of 1 mill on each dollar of assessed valuation of said county, the question of raising by taxation or borrowing such amounts as may be deemed necessary, shall be submitted to the electors of the county at any general election or at a special election called for that purpose. Said question shall be submitted and election held and conducted and returns thereof canvassed and declared in the same manner as is or may be provided by the general election law for the submission and determination of the question of issuing county bonds. If a majority of the electors of the county voting thereon authorize the raising of such additional sum or sums, the board of supervisors shall by resolution direct the raising of the same by taxation.
